Definitions
- the invention relates to a door arrester for detecting a motor vehicle door or a method for blocking a door arrester.
- the door arrester comprises a spindle rod which is pivotally connected at one end to a vehicle body and received at the other end in the vehicle door, where a braking or locking device is arranged.
- the braking or locking device is accommodated in a holding housing, wherein the holding housing surrounds the spindle rod substantially rotationally symmetrical.
- the spindle rod passes through a central recess of the holding housing.
- the spindle rod has an external thread, which is in engagement with an internal thread of a spindle nut, wherein the spindle nut is rotatably mounted in the holding housing by means of a rolling bearing.
- a longitudinally displaceable electromagnet which is designed as a coil arrangement in a housing, displaces the braking surfaces counter to the force application direction of the spring during energization, so that the brake pad is brought out of material contact with the spindle nut, whereby the spindle nut can rotate freely and the vehicle door is no longer detected, but is released.
- the longitudinally displaceable electromagnet can be triggered by means of sensors.
- DE 10 2007 026 796 A1 shows an electrically controllable door lock for vehicle doors.
- a rack support rod gear housing accommodated, wherein the rack is connected to the body via a bearing.
- the rack is in engagement with a gear of the gear housing, said gear being non-rotatably connected to a transmission gear, which is in engagement with another gear.
- On one end side of the further gear discs are arranged.
- a spring element is received in a coil housing and spaced from an end face of the coil housing, which is designed as a bearing surface, of the brake discs.
- an annular coil is further arranged in an outer region of the coil housing, whereas the spring element is arranged in an inner region of the coil housing.
- the brake discs and the coil housing made of a magnetizable material.
- the magnetization of the material follows in that the brake discs are pressed against the support surface of the bobbin case, so that a frictional connection is formed and the door stops moving. Even with a termination of the energization of the coil, the magnetization is maintained and the vehicle door is secured in position, so that only an oppositely energized coil the brake disc again spaced from the support surface of the coil housing and the door release releases. It is intended to trigger the energization of the door detection by external sensors.
- DE 10 2011 056 225 A1 shows a stepless door arrester, in which a transmission housing is fixed in a holding housing, wherein the holding housing is fixed to a vehicle door.
- the door arrester comprises a spindle rod having a threaded portion and a non-threaded end portion, wherein the spindle rod at its end portion portion comprises a bearing for pivotal connection with the body and at the end portion facing away from the end stop.
- the end stop limits a maximum opening travel of the vehicle door.
- a spindle nut which is rotatably received in the transmission housing, engages with an internal thread in an external thread of the spindle rod. In the area of the unthreaded end section, the spindle nut slides over the spindle rod.
- a displacement of the spindle nut over the spindle rod is Designed as frictionless as possible, so that the vehicle door can open unintentionally, for example, in a gust of wind.
- the spindle nut is additionally provided with an external thread, which is in the manner of a bevel gear with a pinion of a power transmission element engaged.
- a shaft connected to the force transmission element is connected to a cup-shaped friction element, which is resiliently received in a cup-shaped braking surface. If the vehicle door is now moved, the spindle nut rotates about the spindle rod and displaces the spindle rod relative to the transmission housing by generated axial forces.
- a coefficient of friction between the cup-shaped friction member and the braking surface may be selected such that movement of the door has a desired resistance such that, for example, a sudden gust of wind is unable to inadvertently open the vehicle door.
- the end portion of the spindle rod is provided so that during a closing operation of the vehicle door, the spindle nut does not have to rotate about the last distance to the thread of the spindle rod, but can slide over the end portion, so that a braking effect can not engage and closes the vehicle door reliably.
- DE 10 2011 106 664 A1 shows a stepless door lock, in which a trained as a spindle rod support rod is axially displaceably mounted in a holding housing.
- a spindle nut is received in the holding housing.
- the spindle nut is in this case mounted in the manner of a rolling bearing rotatable about an axis of rotation of the spindle rod and has on an inner side a threaded bore which engages with a threaded bore of the spindle rod.
- the holding housing comprises a permanent magnetic material and a cavity, which is formed coaxially to the axis of rotation of the spindle rod, so that an inner Wall with a smaller radius of the holding housing surrounds the spindle rod and an outer wall is arranged with a larger radius spaced from the axis of rotation of the spindle rod.
- the mutually facing sides of the inner wall and the outer wall are magnetically differently polarized.
- the holding housing and the brake shoes are permanently magnetically formed such that in a rest position of the vehicle door, the brake shoes are pressed by magnetic forces on the inner wall of the holding housing, which is arranged rotationally symmetrically between the spindle rod and the holding jaws.
- the brake shoes By resting the brake shoes on the spindle rod facing inner wall of the holding housing of a rotational movement of the spindle nut is opposed to a frictional force.
- the brake shoes By overcoming a breakaway torque, the brake shoes are lifted by means of a centripetal force despite the magnetically attractive effect of the inner wall of the housing and are displaced in a kind of floating state in the cavity between the inner wall and the outer wall.
- the outer wall of the housing is designed as a permanent magnet such that its magnetic force acts repulsively on the brake shoes. If the axial displacement of the spindle clasp, for example, by a gust of wind, significantly increased, so does the rotational speed of the spindle nut and thereby the centripetal force on the brake shoes, so that the repulsion of the outer support housing is overcome and the brake shoes by the increased centripetal force in a material contact reach the outer wall, whereby a frictional force is generated which slows down the rotational speed of the spindle nut and thereby also a displacement speed of the spindle rod.
- the door lock works according to the principle of the centrifugal brake and works without an external power supply.
- FR 2 830 893 A1 describes a lock for a vehicle door, which is hingedly connected to a body part, in which a hingedly connected to the body part holding rod passes through a holder housing which is arranged in the flap, wherein the support rod has a toothed with a gear of the holder housing in Gear engagement is, wherein the gear is coupled to a permanent magnetic armature disc with a plurality of poles, which rotates with the gear opposite a fixed permanent magnetic armature disc.
- oppositely poled portions of the armature discs tend to attract each other and thus counteract further rotation of the movable armature disc, so that for a rotational movement first a force must be applied, which acts as a braking force.
- DE 199 21 213 A1 shows a stepless vehicle door arrester, in which a holding housing is connected via a hinge to a vehicle door or a body, and a spindle rod, which passes through the holding housing in the middle.
- the spindle rod is rotatably connected to the vehicle door or the vehicle body.
- the spindle rod engages in a thread of a spindle nut, wherein the spindle nut is rotatably received in a radial bearing.
- two cup springs are supported on both inner sides of the holding housing in an extension direction of the spindle rod, wherein the disc springs are supported with their concave sides on support surfaces of the holding housing and supported on the opposite convex sides of the spindle nut.
- balls are arranged in ball grooves on the disc springs.
- the ball acts as a pivot point of a lever, so that a peripheral contact surface of the plate spring is lifted from the housing wall, so that the corresponding plate spring is no longer in direct contact with the holding housing, whereby a frictional force between the plate spring and the housing is reduced and the spindle nut is easier to rotate than at the beginning of a sliding process of the spindle rod.
- the disc springs are mounted only by means of the balls on a corresponding holding housing side. It follows that when opening a vehicle door first an increased force must be expended, but that after applying this increased force, a vehicle door is easier to open, as the friction coefficient between disc spring and the spindle nut is lowered.
- DE 44 35 720 A1 or. DE 198 32 502 C2 show a stepless locking device for a vehicle door, wherein in a closing or opening operation, a spindle rod with an external thread is displaced by an internal thread of a rotatable spindle nut.
- the spindle nut is rotatably mounted on a bearing within a holding housing.
- the spindle nut is encompassed by a rope, wherein the two ends of the rope are fastened to a pivoting lever at an attachment point or a plurality of attachment points.
- the pivot lever is subjected to such a force by a compression spring that a biasing force is exerted on the rope.
- the pivot lever By means of an electric motor, which is controllable by external sensors, the pivot lever can be pivoted to the effect that a tension of the rope around the spindle nut dissolves, whereby the braking moments caused by the rope are minimized. In this state, a determination of the vehicle door is released, so that the vehicle door can be closed or opened.
- a door fastener for a vehicle door comprising a support bar connectable to one of both door assembly parts door and door frame, wherein a support housing is connectable to the other door assembly part.
- a spindle rod in a cavity of the support rod is axially displaceable received or received.
- the spindle rod is advantageously protected by the surrounding support rod, so that, for example, prevents dust or dirt settle in a thread of the spindle rod and thereby inhibit movement of the spindle rod ,
- a space is optimally utilized by the spindle rod is received axially displaceable in the support rod and takes no additional space outside the support rod for the axial displacement to complete.
- the axial displaceability ensures that the spindle rod is coupled to an opening and / or closing movement of the vehicle door.
- a spatially fixed spindle rod can not be coupled to a movement process.
- the spindle rod is mounted centrally by a receptacle in the support rod within the door arrester, so that occurring forces attack evenly on the spindle rod.
- the door arrester can be used to quickly and reliably stop the movement of the vehicle door by means of a sensor system. This is necessary, for example, if the vehicle door would otherwise collide with another vehicle, a stationary object such as a wall, or a mobile road user.
- a spindle nut rotatably disposed, wherein in the spindle nut, a spindle rod is connected.
- the spindle nut is arranged on the dimensionally stable support rod, it is achieved that a rotationally fixed arrangement of the spindle nut at an axial pressure exerted by the spindle rod, the support rod is not damaged, it may for example be the case with a more unstable component ,
- the axial movement of the support rod is converted by means of the spindle nut in a rotational movement of the spindle rod.
- a braking mechanism specially designed to stop the rotational movements.
- Such a braking mechanism offers the possibility of being able to be built in addition to an axially acting brake mechanism of the door arrester, which leads to an increase in redundancy.
- the axial displacement can be transformed by means of a suitably selected gear ratio into a rotational movement, which in principle can be freely selected.
- the number of turns of the spindle rod per unit length determines the number of rotations of the spindle rod.
- the spindle nut is arranged on an end region of the support rod.
- this provides the ability to easily install the spindle nut but easy to replace even if damaged.
- a dimension of the support rod can be made smaller, otherwise the spindle nut would have to be completely absorbed into the cavity of the support rod. Inevitably, this leads to a larger dimension of the support rod.
- this arrangement has the advantage that the length of the spindle rod is kept as small as possible, since the opening movement of the vehicle door of a certain Displacement of the spindle rod corresponds. If the spindle nut were connected inside the support rod, then the spindle rod would have to be extended by a distance from the end portion of the support rod to the bearing of the spindle nut inside the support rod.
- the spindle rod is proportional to a pivoting of the door out of the support bar moved out. This ensures that a pivoting movement of the vehicle door is directly coupled to the movement of the spindle rod, so that stopping the movement of the spindle rod also stops the pivoting movement of the vehicle door.
- the spindle rod essentially has a straight extension. This ensures that the spindle rod can move axially within the support rod, and thereby lateral dimensions of the support rod are kept small.
- a curved, flexible spindle rod can be used.
- the holding rod essentially has a straight extension.
- the spindle rod which is preferably also formed in a straight extension, is axially displaceable within the support rod, and thereby lateral dimensions of the support rod are kept small.
- a curved support bar may be used, which is a curved one adapted spindle rod is adapted and / or the pivotal movement of the vehicle door is adjusted.
- the support rod offset a stationary mounted disc in a rotary motion, wherein the disc can be locked without contact by an electrically driven locking means.
- an opening movement of the vehicle door is coupled to the rotational movement of the stationary mounted disc, so that advantageously the opening movement of the vehicle door can be stopped by an electrically driven rotational movement blocking means.
- the contactless locking of the disc ensures advantageous that no material wear or abrasion takes place and the lock works consistently and reliably, even after numerous processes.
- the disc is designed as a permanent magnetic armature disc with at least two magnetic poles, wherein the electrically driven blocking means acts by means of electromagnetic force on the acting as a permanent magnetic armature disc.
- the electrically driven blocking means acts by means of electromagnetic force on the acting as a permanent magnetic armature disc.
- the permanent magnetic armature disc is non-rotatably connected to a spindle rod. It follows that the rotational speed of the spindle rod is transmitted directly to the armature disk, so that both the armature disk and the spindle rod have the same rotational speed. It follows that at a locking the anchor plate at the same time the spindle rod is locked.
- the permanent magnet armature disc has a signal-generating sensor, wherein the signal-generating sensor detects revolutions of the permanent magnet armature disc.
- the signal-generating sensor detects revolutions of the permanent magnet armature disc.
- a measurement of the number of revolutions of the permanent magnet armature disk can be converted to a current opening position of the vehicle door.
- the axial displacement of the spindle rod in turn is in a functional relationship with an opening angle of the vehicle door.
- the number of rotations can thus be converted to the currently occupied position of the vehicle door, thus it can be calculated how far away the vehicle door from other objects that are detected by means of a sensor.
- the electrically driven blocking means is designed as an electromagnet, wherein the electromagnet is provided as a coil arrangement which forms at least four magnetic poles.
- the electrically drivable blocking means can act without contact, and also that the electrically drivable blocking means can interact with the permanent magnetic armature disk.
- an electrically driven blocking agent can be activated as needed, so that, for example, sensors trigger the electrically driven blocking agent.
- the provision of at least four magnetic poles of the electromagnet, in combination with the two poles of the permanent magnetic armature disk makes it possible to lock a rotational movement of the armature disk after at least 45 °, if a magnetic field strength is correspondingly strong.
- two, four, six or eight magnetic poles of the electromagnet can be provided, wherein the number of magnetic poles affects an angular range, which sweeps over the armature disc to the lock.
- the electromagnet and the permanent magnetic armature disk form a so-called wrap-around turntable, wherein the wrap-around turntable locks a rotational movement of the permanent-magnet armature disk contactlessly.
- the winding turntable allows that the permanent magnet armature disc can rotate at most by 45 ° when energizing the electromagnet. It follows that the more the number of turns per unit length along the extension of the spindle rod, the more the pivoting of the vehicle door can be stopped, because in this case the number of rotations of the armature disk is increased for a certain displacement.
- a bearing for a spindle rod is arranged on the holding housing.
- the bearing advantageously allows the spindle rod to rotate reliably and uniformly and perpendicular to the axis of rotation and in the direction of the axis of rotation acting forces can be absorbed by the bearing of the holding housing.
- the spindle rod is held stationary and is rotated by the associated spindle nut in a rotary motion.
- a door arrester for a vehicle door wherein a support rod is connectable to one of both door assembly parts door and door frame, wherein a holding housing is connectable to the other door assembly part.
- a cup portion is connected to the holding housing, in which the support rod is at least partially inserted.
- the cup portion allows the movable or rotationally movable parts to be received in the cup portion and thereby protected.
- the cup portion is preferably arranged on the holding housing via legs.
- the legs thereby form a holding device for the cup portion.
- the legs are arranged along an extension direction of the support rod, so that the legs cover portions of the support rod, which need not be protected to the same extent against dirt storage as a thread of the spindle rod.
- the spindle rod is mounted in a deep groove ball bearing in the cup section. This advantageously makes it possible for the spindle rod to be mounted with as little rotation as possible in the cup portion, wherein the cup portion receives forces which run and act perpendicular to the axis of rotation of the spindle rod.
- a mechanical Brake arrangement arranged in the holding housing, wherein an acting on the support rod electric brake assembly is provided outside the also acting on the support rod mechanical brake assembly. It is advantageously achieved by this manner that the pivoting of the vehicle door can be braked by two different mechanisms, both of which act on the support rod.
- the mechanical brake arrangement brakes the pivoting of the vehicle door evenly and in accordance with an actuation by a user, wherein the electrical brake arrangement by means of sensors is able to carry out an emergency locking of the vehicle door, if the vehicle door otherwise fails, for example, against another vehicle, would beat another road user or other objects.
- the mechanical brake arrangement outside the electronic brake arrangement, it is advantageously achieved that both can act at different positions of the door arrester.
- the mechanical brake assembly along the extension of the support rod is guided offset parallel to a surface side of the support rod.
- the parallel offset guidance of the mechanical brake assembly along the extension of the support rod ensures that the mechanical brake assembly can act on the support rod over an entire range of motion of the door arrester. During a pivoting movement thus takes place a relative movement between the support rod and the mechanical brake assembly in the way that both components have consistent material contact.
- the mechanical brake arrangement preferably acts on a broad surface side.
- the mechanical brake assembly is biased by at least one of the surface sides by means of a spring member.
- This bias opposes the opening movement with a frictional resistance that prevents the vehicle door from striking too strongly at an end position of the pivoting.
- the spring member may be formed as a gas spring, a coil spring or another type of spring his. The spring member allows a reliable, safe and inexpensive bias, which generates the frictional resistance between the mechanical brake assembly and one of the surface sides, so that the pivoting of the vehicle door is opposed to a braking torque.
- the holding bar preferably has a profiling along its extension, at least on one of the surface sides.
- the profiling has, for example, two raised sections and two recessed sections.
- the profiling is formed by three raised sections and by three recessed sections.
- the number of recessed and raised sections can also be unequal.

Description
Die Erfindung betrifft einen Türfeststeller zum Feststellen einer Kraftfahrzeugtür bzw. ein Verfahren zum Blockieren eines Türfeststellers.The invention relates to a door arrester for detecting a motor vehicle door or a method for blocking a door arrester.
Es ist die Aufgabe der Erfindung, einen Türfeststeller zu schaffen, der ein zuverlässiges und sicheres automatisiertes Feststellen einer Fahrzeugtür ermöglicht.It is the object of the invention to provide a door arrester, which allows a reliable and safe automated locking a vehicle door.
Diese Aufgabe wird erfindungsgemäß durch einen Türfeststeller bzw. ein Verfahren zum Blockieren eines Türfeststellers mit den Merkmalen eines unabhängigen Anspruchs gelöst.This object is achieved by a door arrester and a method for blocking a door arrester with the features of an independent claim.
Gemäß der Erfindung ist ein Türfeststeller für eine Fahrzeugtür geschaffen, der eine Haltestange, die an einem von beiden Türanordnungsteilen Tür und Türrahmen anschließbar ist, umfasst, wobei ein Haltegehäuse an dem anderen Türanordnungsteil anschließbar ist. Hierbei ist eine Spindelstange in einem Hohlraum der Haltestange axial verschiebbar aufnehmbar bzw. aufgenommen. Dadurch, dass die Spindelstange in dem Hohlraum der Haltestange axial verschiebbar aufgenommen ist, wird vorteilhaft die Spindelstange durch die umgebende Haltestange geschützt, sodass beispielsweise vermieden wird, dass sich Staub bzw. Dreck in ein Gewinde der Spindelstange festsetzen und dadurch eine Bewegung der Spindelstange hemmen kann. Zudem wird vorteilhaft erreicht, dass ein Raumangebot optimal ausgenutzt wird, indem die Spindelstange in der Haltestange axial verschiebbar aufgenommen ist und keinen zusätzlichen Raum außerhalb der Haltestange für die axiale Verschiebung in Anspruch nimmt. Vorteilhaft gewährleistet die axiale Verschiebbarkeit, dass die Spindelstange an eine Öffnungs- und/oder Schließbewegung der Fahrzeugtür gekoppelt ist. Eine räumlich fixierte Spindelstange kann nicht an einen Bewegungsvorgang gekoppelt werden. Weiter vorteilhaft ist die Spindelstange durch eine Aufnahme in der Haltestange mittig innerhalb des Türfeststellers gelagert, sodass auftretende Kräfte gleichmäßig an der Spindelstange angreifen. Der Türfeststeller kann mittels einer Sensorik die Bewegung der Fahrzeugtür schnell und zuverlässig zu stoppen. Dies ist beispielsweise notwendig, wenn die Fahrzeugtür andernfalls mit einem anderen Fahrzeug, einem feststehenden Gegenstand, wie beispielsweise einer Mauer, oder einem beweglichen Verkehrsteilnehmer kollidieren würde.According to the invention, there is provided a door fastener for a vehicle door comprising a support bar connectable to one of both door assembly parts door and door frame, wherein a support housing is connectable to the other door assembly part. Here, a spindle rod in a cavity of the support rod is axially displaceable received or received. Characterized in that the spindle rod is received axially displaceable in the cavity of the support rod, the spindle rod is advantageously protected by the surrounding support rod, so that, for example, prevents dust or dirt settle in a thread of the spindle rod and thereby inhibit movement of the spindle rod , In addition, it is advantageously achieved that a space is optimally utilized by the spindle rod is received axially displaceable in the support rod and takes no additional space outside the support rod for the axial displacement to complete. Advantageously, the axial displaceability ensures that the spindle rod is coupled to an opening and / or closing movement of the vehicle door. A spatially fixed spindle rod can not be coupled to a movement process. Further advantageously, the spindle rod is mounted centrally by a receptacle in the support rod within the door arrester, so that occurring forces attack evenly on the spindle rod. The door arrester can be used to quickly and reliably stop the movement of the vehicle door by means of a sensor system. This is necessary, for example, if the vehicle door would otherwise collide with another vehicle, a stationary object such as a wall, or a mobile road user.
Weiterhin ist beim erfindungsgemäßen Türfeststeller an der Haltestange eine Spindelmutter drehfest angeordnet, wobei in der Spindelmutter eine Spindelstange angeschlossen ist. Hierdurch wird vorteilhaft erreicht, dass die Spindelmutter bei einer axialen Bewegung der Spindelstange bei dem Öffnungs- und/oder Schließvorgang der Fahrzeugtür fest an dem Türfeststeller angeschlossen ist und der Spindelstange dadurch ein Kraftmoment entgegensetzt, sodass die Spindelstange in eine Rotationsbewegung versetzt wird, wenn die Haltestange und das Haltegehäuse gegenseitig axial verschoben wird. Hierbei ist die Rotationsgeschwindigkeit der Spindelstange durch die Anzahl der Windungen auf der Spindelstange pro Streckeneinheit festgelegt. Je mehr Windungen pro Streckeneinheit vorhanden sind, desto höher ist die Rotationsgeschwindigkeit der Spindelstange bei gleichbleibender Öffnungsgeschwindigkeit der Fahrzeugtür. Dadurch, dass die Spindelmutter an der formstabilen Haltestange angeordnet ist, wird erreicht, dass eine drehfeste Anordnung der Spindelmutter bei einem axialen Druck, welcher durch die Spindelstange ausgeübt wird, ein die Haltestange nicht beschädigt, wies es beispielsweise bei einem instabileren Bauteil der Fall sein könnte.Furthermore, in the door lock according to the invention on the support rod, a spindle nut rotatably disposed, wherein in the spindle nut, a spindle rod is connected. This advantageously achieves that the spindle nut during an axial movement of the spindle rod is firmly connected to the door lock in the opening and / or closing operation of the vehicle door and thereby the spindle rod opposes a moment of force, so that the spindle rod is set in a rotational movement when the support rod and the support housing is mutually displaced axially. Here, the rotational speed of the spindle rod is determined by the number of turns on the spindle rod per track unit. The more turns per track unit are present, the higher the rotational speed of the spindle rod is at a constant opening speed of the vehicle door. Characterized in that the spindle nut is arranged on the dimensionally stable support rod, it is achieved that a rotationally fixed arrangement of the spindle nut at an axial pressure exerted by the spindle rod, the support rod is not damaged, it may for example be the case with a more unstable component ,
Die axiale Bewegung der Haltestange wird mittels der Spindelmutter in eine Rotationsbewegung der Spindelstange umgewandelt. Vorteilhaft ist es dadurch möglich, einen Bremsmechanismus anzuwenden, welche speziell darauf ausgelegt sind, die Rotationsbewegungen zu stoppen.Ein solcher Bremsmechanismus bietet die Möglichkeit, dass er zusätzlich zu einem axial wirkenden Bremsmechanismus des Türfeststellers verbaubar ist, was zu einer Erhöhung der Redundanz führt. Natürlich kann auch nur der auf die Rotationsbewegung wirkender Bremsmechanismus verbaut sein, um die Bewegung der Fahrzeugtür zu stoppen. Insbesondere kann die axiale Verschiebung mittels einer geeignet gewählten Übersetzung in eine im Prinzip freiwählbare Rotationsbewegung transformiert werden. Im vorliegenden Fall legt die Windungsanzahl der Spindelstange pro Längeneinheit die Anzahl der Rotationen der Spindelstange fest. Um einen möglichst präzisen Stoppvorgang bei der Öffnungs- und/ oder Schließbewegung der Fahrzeugtür zu erzielen, ist es vorteilhaft die Übersetzung so zu wählen, dass sich eine hohe Anzahl an Rotationen der Spindelstange ergibt, sodass eine große Zahl von Umdrehungen der Spindelstange einer kleinen axialen Verschiebung der Haltestange entspricht.The axial movement of the support rod is converted by means of the spindle nut in a rotational movement of the spindle rod. Advantageously, it is thereby possible to apply a braking mechanism specially designed to stop the rotational movements. Such a braking mechanism offers the possibility of being able to be built in addition to an axially acting brake mechanism of the door arrester, which leads to an increase in redundancy. Of course, only the braking mechanism acting on the rotational movement can be installed to stop the movement of the vehicle door. In particular, the axial displacement can be transformed by means of a suitably selected gear ratio into a rotational movement, which in principle can be freely selected. In the present case, the number of turns of the spindle rod per unit length determines the number of rotations of the spindle rod. In order to achieve a precise stopping operation in the opening and / or closing movement of the vehicle door, it is advantageous to choose the translation so that there is a high number of rotations of the spindle rod, so that a large number of revolutions of the spindle rod of a small axial displacement the handrail corresponds.
In bevorzugter Ausgestaltung ist die Spindelmutter an einem Endbereich der Haltestange angeordnet. Vorteilhaft bietet dies die Möglichkeit, die Spindelmutter leicht einzubauen aber auch bei einer Beschädigung leicht auszutauschen zu können. Zudem kann dadurch eine Abmessung der Haltestange kleiner gewählt werden, da andernfalls die Spindelmutter gänzlich in den Hohlraum der Haltestange aufgenommen werden müsste. Zwangsläufig führt die zu einer größeren Abmessung der Haltestange. Zusätzlich bietet diese Anordnung den Vorteil, dass die Länge der Spindelstange möglichst klein gehalten ist, da die Öffnungsbewegung der Fahrzeugtür einer bestimmten Verlagerung der Spindelstange entspricht. Wäre die Spindelmutter im Inneren der Haltestange angeschlossen, so müsste die Spindelstange um einer Streckenlänge von dem Endbereich der Haltestange bis zur Lagerung der Spindelmutter im Inneren der Haltestange verlängert werden.In a preferred embodiment, the spindle nut is arranged on an end region of the support rod. Advantageously, this provides the ability to easily install the spindle nut but easy to replace even if damaged. In addition, thereby a dimension of the support rod can be made smaller, otherwise the spindle nut would have to be completely absorbed into the cavity of the support rod. Inevitably, this leads to a larger dimension of the support rod. In addition, this arrangement has the advantage that the length of the spindle rod is kept as small as possible, since the opening movement of the vehicle door of a certain Displacement of the spindle rod corresponds. If the spindle nut were connected inside the support rod, then the spindle rod would have to be extended by a distance from the end portion of the support rod to the bearing of the spindle nut inside the support rod.
Zweckmäßigerweise ist die Spindelstange proportional zu einem Verschwenkweg der Tür aus der Haltestange herausfahrbar. Hierdurch wird erreicht, dass eine Schwenkbewegung der Fahrzeugtür direkt an die Bewegung der Spindelstange gekoppelt ist, sodass ein Stoppen der Bewegung der Spindelstange ebenfalls die Schwenkbewegung der Fahrzeugtür stoppt. Weiter zweckmäßig weist die Spindelstange im Wesentlichen eine gerade Erstreckung auf. Hierdurch wird erreicht, dass sich die Spindelstange innerhalb der Haltestange axial verschieben kann, und dass dadurch seitliche Abmessungen der Haltestange klein gehalten sind. Alternativ kann eine gekrümmte, flexible Spindelstange verwendet werden.Appropriately, the spindle rod is proportional to a pivoting of the door out of the support bar moved out. This ensures that a pivoting movement of the vehicle door is directly coupled to the movement of the spindle rod, so that stopping the movement of the spindle rod also stops the pivoting movement of the vehicle door. Further expediently, the spindle rod essentially has a straight extension. This ensures that the spindle rod can move axially within the support rod, and thereby lateral dimensions of the support rod are kept small. Alternatively, a curved, flexible spindle rod can be used.
Weiter zweckmäßig weist die Haltestange im Wesentlichen eine gerade Erstreckung auf. Hierdurch ist sichergestellt, dass sich die Spindelstange, welche bevorzugt ebenfalls in einer geraden Erstreckung ausgebildet ist, innerhalb der Haltestange axial verschiebbar ist, und dass dadurch seitliche Abmessungen der Haltestange klein gehalten sind. Alternativ kann eine gekrümmte Haltestange verwendet werden, welche eine gekrümmt ausgestalteten Spindelstange angepasst ist und/oder der Schwenkbewegung der Fahrzeugtür angepasst ist.Further expediently, the holding rod essentially has a straight extension. This ensures that the spindle rod, which is preferably also formed in a straight extension, is axially displaceable within the support rod, and thereby lateral dimensions of the support rod are kept small. Alternatively, a curved support bar may be used, which is a curved one adapted spindle rod is adapted and / or the pivotal movement of the vehicle door is adjusted.
Gemäß einer bevorzugten Weiterbildung der Erfindung versetzt die Haltestange eine ortsfest gelagerte Scheibe in eine Drehbewegung, wobei die Scheibe durch ein elektrisch antreibbares Blockiermittel berührungslos arretierbar ist. Indem die Haltestange die ortsfest gelagerte Scheibe in eine Drehbewegung versetzt, wird eine Öffnungsbewegung der Fahrzeugtür an die Drehbewegung der ortsfest gelagerten Scheibe gekoppelt, sodass vorteilhaft die Öffnungsbewegung der Fahrzeugtür durch ein elektrisch antreibbares Rotationsbewegungsblockiermittel gestoppt werden kann. Das berührungslose Arretieren der Scheibe gewährleistet vorteilhaft, dass kein Materialverschleiß oder Abrieb stattfindet und die Arretierung auch nach zahlreichen Vorgängen gleichbleibend und zuverlässig funktioniert.According to a preferred embodiment of the invention, the support rod offset a stationary mounted disc in a rotary motion, wherein the disc can be locked without contact by an electrically driven locking means. By the holding rod sets the stationary mounted disc in a rotational movement, an opening movement of the vehicle door is coupled to the rotational movement of the stationary mounted disc, so that advantageously the opening movement of the vehicle door can be stopped by an electrically driven rotational movement blocking means. The contactless locking of the disc ensures advantageous that no material wear or abrasion takes place and the lock works consistently and reliably, even after numerous processes.
Bevorzugt ist die Scheibe als permanentmagnetische Ankerscheibe mit zumindest zwei magnetischen Polen ausgebildet, wobei das elektrisch antreibbare Blockiermittel mittels elektromagnetischer Kraftwirkung auf die als permanentmagnetische Ankerscheibe wirkt. Dies gewährleistet vorteilhaft, dass magnetische Kräfte eingesetzt werden können, um die permanentmagnetische Ankerscheibe zu stoppen. Durch die Ausbildung von zumindest zweier magnetischer Pole der Ankerscheibe kann die permanentmagnetische Ankerscheibe in einem Magnetfeld an bevorzugten Positionen festgestellt werden, indem an diesen Positionen Energieminima ausgebildet sind. Permanentmagneten weisen die Eigenschaft auf, dass sie über lange Zeiträume ihre permanentmagnetischen Eigenschaften im Wesentlichen unverändert beibehalten. Daraus folgt, dass die Ankerscheibe unabhängig von einer Stromzufuhr, was beispielsweise bei einem Elektromagneten der Fall ist, funktioniert. Zudem bietet die elektromagnetische Wechselwirkung die Möglichkeit einer berührungslosen Arretierung. Hierbei ist es möglich vier, sechs oder acht magnetische Pole zu verwenden. Wird eine Anzahl der magnetischen Pole zu groß, folgt hieraus jedoch eine Abnahme der elektromagnetischen Kraftwirkung auf die Ankerscheibe, da sich die elektromagnetischen Felder gegenseitig zu stark beeinflussen und dadurch, je nach Anordnung, auch schwächen könnten.Preferably, the disc is designed as a permanent magnetic armature disc with at least two magnetic poles, wherein the electrically driven blocking means acts by means of electromagnetic force on the acting as a permanent magnetic armature disc. This advantageously ensures that magnetic forces can be used to stop the permanent magnet armature disk. By forming at least two magnetic poles of the armature disk, the permanent magnet armature disk can be detected in a magnetic field at preferred positions by energy minima are formed at these positions. Permanent magnets have the property that they maintain their permanent magnetic properties substantially unchanged over long periods of time. It follows that the armature disc operates independently of a power supply, which is the case for example with an electromagnet. In addition, the electromagnetic interaction offers the possibility of a contactless locking. Here it is possible four, to use six or eight magnetic poles. However, if a number of the magnetic poles becomes too large, this will result in a decrease in the electromagnetic force acting on the armature disk, since the electromagnetic fields would influence one another too strongly and thereby also weaken, depending on the arrangement.
In einer bevorzugten Ausgestaltung ist die permanentmagnetische Ankerscheibe drehfest mit einer Spindelstange verbunden. Hieraus folgt, dass die Rotationsgeschwindigkeit der Spindelstange direkt auf die Ankerscheibe übertragen wird, sodass sowohl die Ankerscheibe als auch die Spindelstange dieselbe Rotationsgeschwindigkeit aufweisen. Hieraus folgt, dass bei einem arretieren der Ankerscheibe zugleich die Spindelstange arretiert wird.In a preferred embodiment, the permanent magnetic armature disc is non-rotatably connected to a spindle rod. It follows that the rotational speed of the spindle rod is transmitted directly to the armature disk, so that both the armature disk and the spindle rod have the same rotational speed. It follows that at a locking the anchor plate at the same time the spindle rod is locked.
Zweckmäßigerweise weist die permanentmagnetische Ankerscheibe einen signalerzeugenden Sensor auf, wobei der signalerzeugende Sensor Umdrehungen der permanentmagnetischen Ankerscheibe detektiert. Dadurch kann der signalerzeugende Sensor Signale an ein angeschlossenes elektronisches System weitergeben, in dem Signale weiter verarbeitet werden können. Eine Messung der Anzahl der Umdrehungen der permanentmagnetischen Ankerscheibe kann auf eine momentane Öffnungsstellung der Fahrzeugtür umgerechnet werden. Vorteilhaft ist es dadurch möglich zu berechnen, wie weit die Fahrzeugtür geöffnet ist, da die Anzahl der Rotationen in einem funktionalen Zusammenhang mit der axialen Verschiebung der Spindelstange steht. Die axiale Verschiebung der Spindelstange steht wiederum in einem funktionalen Zusammenhang mit einem Öffnungswinkel der Fahrzeugtür. Die Anzahl der Rotationen lässt sich also auf die momentan eingenommene Position der Fahrzeugtür umrechnen, somit kann berechnet werden, wie weit die Fahrzeugtür von anderen Gegenständen, die mittels einer Sensorik detektiert werden, entfernt ist.Conveniently, the permanent magnet armature disc has a signal-generating sensor, wherein the signal-generating sensor detects revolutions of the permanent magnet armature disc. This allows the signal-generating sensor to pass signals to a connected electronic system in which signals can be further processed. A measurement of the number of revolutions of the permanent magnet armature disk can be converted to a current opening position of the vehicle door. Advantageously, it is thereby possible to calculate how far the vehicle door is opened, since the number of rotations is in a functional relationship with the axial displacement of the spindle rod. The axial displacement of the spindle rod in turn is in a functional relationship with an opening angle of the vehicle door. The number of rotations can thus be converted to the currently occupied position of the vehicle door, thus it can be calculated how far away the vehicle door from other objects that are detected by means of a sensor.
Bevorzugt ist das elektrisch antreibbare Blockiermittel als ein Elektromagnet ausgebildet, wobei der Elektromagnet als eine Spulenanordnung, welche zumindest vier magnetische Pole ausbildet, vorgesehen ist. Dies ermöglicht, dass das elektrisch antreibbare Blockiermittel berührungslos wirken kann, und auch, dass das elektrisch antreibbare Blockiermittel mit der permanentmagnetischen Ankerscheibe interagieren kann. Zudem kann ein elektrisch angetriebenes Blockiermittel bei Bedarf aktiviert werden, sodass beispielsweise Sensoren das elektrisch antreibbare Blockiermittel triggern. Das Vorsehen von zumindest vier magnetischen Polen des Elektromagnet ermöglicht in Kombination mit den zwei Polen der permanentmagnetischen Ankerscheibe, dass eine Rotationsbewegung der Ankerscheibe nach wenigstens 45° arretierbar ist, wenn eine magnetische Feldstärke entsprechend stark ausgebildet ist. Alternativ können auch zwei, vier, sechs oder acht magnetische Pole des Elektromagneten vorgesehen sein, wobei die Anzahl der magnetischen Pole einen Winkelbereich beeinflusst, welchen die Ankerscheibe bis zur Arretierung überstreicht.Preferably, the electrically driven blocking means is designed as an electromagnet, wherein the electromagnet is provided as a coil arrangement which forms at least four magnetic poles. This makes possible, in that the electrically drivable blocking means can act without contact, and also that the electrically drivable blocking means can interact with the permanent magnetic armature disk. In addition, an electrically driven blocking agent can be activated as needed, so that, for example, sensors trigger the electrically driven blocking agent. The provision of at least four magnetic poles of the electromagnet, in combination with the two poles of the permanent magnetic armature disk, makes it possible to lock a rotational movement of the armature disk after at least 45 °, if a magnetic field strength is correspondingly strong. Alternatively, two, four, six or eight magnetic poles of the electromagnet can be provided, wherein the number of magnetic poles affects an angular range, which sweeps over the armature disc to the lock.
Bevorzugt bilden der Elektromagnet und die permanentmagnetische Ankerscheibe einen sogenannten Einwicklungsdrehsteller aus, wobei der Einwicklungsdrehsteller eine Rotationsbewegung der permanentmagnetischen Ankerscheibe berührungslos arretiert. Hierbei ermöglicht der Einwicklungsdrehsteller, dass sich die permanentmagnetische Ankerscheibe bei einer Bestromung des Elektromagneten höchstens noch um 45° drehen kann. Hieraus folgt, dass die Verschwenkung der Fahrzeugtür umso präziser gestoppt werden kann, je höher die Anzahl der Windungen pro Streckeneinheit entlang der Erstreckung der Spindelstange ist, da in diesem Fall für einen bestimmten Verlagerungsweg die Anzahl der Rotationen der Ankerscheibe erhöht ist.Preferably, the electromagnet and the permanent magnetic armature disk form a so-called wrap-around turntable, wherein the wrap-around turntable locks a rotational movement of the permanent-magnet armature disk contactlessly. In this case, the winding turntable allows that the permanent magnet armature disc can rotate at most by 45 ° when energizing the electromagnet. It follows that the more the number of turns per unit length along the extension of the spindle rod, the more the pivoting of the vehicle door can be stopped, because in this case the number of rotations of the armature disk is increased for a certain displacement.
Gemäß einer weiteren bevorzugten Weiterbildung der Erfindung ist an dem Haltegehäuse ein Lager für eine Spindelstange angeordnet. Hierbei ermöglicht das Lager vorteilhaft, dass sich die Spindelstange zuverlässig und gleichmäßig drehen kann und senkrecht zur Rotationsachse sowie in Richtung der Rotationsachse wirkende Kräfte von dem Lager des Haltegehäuses aufnehmbar sind. Die Spindelstange ist dabei ortsfest gehalten und wird durch die zugehörige Spindelmutter in eine Drehbewegung versetzt.According to a further preferred embodiment of the invention, a bearing for a spindle rod is arranged on the holding housing. In this case, the bearing advantageously allows the spindle rod to rotate reliably and uniformly and perpendicular to the axis of rotation and in the direction of the axis of rotation acting forces can be absorbed by the bearing of the holding housing. The spindle rod is held stationary and is rotated by the associated spindle nut in a rotary motion.
Gemäß einem Aspekt ist ein Türfeststeller für eine Fahrzeugtür geschaffen, wobei eine Haltestange an einem von beiden Türanordnungsteilen Tür und Türrahmen anschließbar ist, wobei ein Haltegehäuse an dem anderen Türanordnungsteil anschließbar ist. Hierbei ist an dem Haltegehäuse ein Napfabschnitt angeschlossen, in den die Haltestange zumindest teilweise einführbar ist. Vorteilhaft ermöglicht der Napfabschnitt, dass die beweglichen beziehungsweise rotationsbeweglichen Teile in dem Napfabschnitt aufgenommen sind und dadurch geschützt werden.According to one aspect, a door arrester for a vehicle door is provided, wherein a support rod is connectable to one of both door assembly parts door and door frame, wherein a holding housing is connectable to the other door assembly part. Here, a cup portion is connected to the holding housing, in which the support rod is at least partially inserted. Advantageously, the cup portion allows the movable or rotationally movable parts to be received in the cup portion and thereby protected.
Bevorzugt ist der Napfabschnitt über Schenkel an dem Haltegehäuse angeordnet. Vorteilhaft bilden die Schenkel hierdurch eine Haltevorrichtung für den Napfabschnitt aus. Die Schenkel sind entlang einer Erstreckungsrichtung der Haltestange angeordnet, sodass die Schenkel Teilbereiche der Haltestange abdecken, welche nicht in demselben Maße vor Schmutzeinlagerung geschützt werden müssen wie ein Gewinde der Spindelstange. Mittels der Schenkel kann der Napfabschnitt zuverlässig gelagert werden, sodass dieser rotationsbeweglichen Teile sicher in seinem Inneren aufnimmt und zugleich schützt.The cup portion is preferably arranged on the holding housing via legs. Advantageously, the legs thereby form a holding device for the cup portion. The legs are arranged along an extension direction of the support rod, so that the legs cover portions of the support rod, which need not be protected to the same extent against dirt storage as a thread of the spindle rod. By means of the legs of the cup portion can be stored reliably, so that this rotatable movable parts safely accommodates in its interior and at the same time protects.
Bevorzugt ist die Spindelstange in einem Rillenkugellager in dem Napfabschnitt gelagert. Hierdurch wird vorteilhaft ermöglicht, dass die Spindelstange möglichst rotationsarm in dem Napfabschnitt gelagert ist, wobei der Napfabschnitt Kräfte aufnimmt, welche senkrecht zur Rotationsachse der Spindelstange verlaufen und wirken.Preferably, the spindle rod is mounted in a deep groove ball bearing in the cup section. This advantageously makes it possible for the spindle rod to be mounted with as little rotation as possible in the cup portion, wherein the cup portion receives forces which run and act perpendicular to the axis of rotation of the spindle rod.
Gemäß einer weiteren bevorzugten Weiterbildung der Erfindung ist eine mechanische Bremsanordnung in dem Haltegehäuse angeordnet, wobei eine auf die Haltestange wirkende elektrische Bremsanordnung außerhalb der ebenfalls auf die Haltestange wirkenden mechanischen Bremsanordnung vorgesehen ist. Vorteilhaft wird durch diese Art und Weise erreicht, dass die Verschwenkung der Fahrzeugtür durch zwei unterschiedliche Mechanismen gebremst werden kann, welche beide auf die Haltestange wirken. Hierbei ist vorteilhaft vorgesehen, dass die mechanische Bremsanordnung die Verschwenkung der Fahrzeugtür gleichmäßig und gemäß einer Betätigung durch einen Benutzers bremst, wobei die elektrische Bremsanordnung mittels Sensoren in der Lage ist, eine Notarretierung der Fahrzeugtür auszuführen, falls die Fahrzeugtür andernfalls beispielsweise gegen ein anderes Fahrzeug, einen anderen Verkehrsteilnehmer oder sonstige Gegenstände schlagen würde. Indem die mechanische Bremsanordnung außerhalb der elektronischen Bremsanordnung angeordnet ist, wird vorteilhaft erreicht, dass beide an unterschiedlichen Positionen des Türfeststellers wirken können.According to another preferred embodiment of the invention is a mechanical Brake arrangement arranged in the holding housing, wherein an acting on the support rod electric brake assembly is provided outside the also acting on the support rod mechanical brake assembly. It is advantageously achieved by this manner that the pivoting of the vehicle door can be braked by two different mechanisms, both of which act on the support rod. In this case, it is advantageously provided that the mechanical brake arrangement brakes the pivoting of the vehicle door evenly and in accordance with an actuation by a user, wherein the electrical brake arrangement by means of sensors is able to carry out an emergency locking of the vehicle door, if the vehicle door otherwise fails, for example, against another vehicle, would beat another road user or other objects. By arranging the mechanical brake arrangement outside the electronic brake arrangement, it is advantageously achieved that both can act at different positions of the door arrester.
Bevorzugt ist die mechanische Bremsanordnung entlang der Erstreckung der Haltestange parallel versetzt zu einer Oberflächenseite der Haltestange geführt. Die parallel versetzte Führung der mechanischen Bremsanordnung entlang der Erstreckung der Haltestange gewährleistet, dass die mechanische Bremsanordnung über einen gesamten Bewegungsbereich des Türfeststellers auf die Haltestange wirken kann. Während einer Schwenkbewegung findet also eine Relativbewegung zwischen der Haltestange und der mechanischen Bremsanordnung in der Art statt, dass beide Bauteile beständig Materialkontakt haben. Vorzugsweise beaufschlagt die mechanische Bremsanordnung eine breite Oberflächenseite.Preferably, the mechanical brake assembly along the extension of the support rod is guided offset parallel to a surface side of the support rod. The parallel offset guidance of the mechanical brake assembly along the extension of the support rod ensures that the mechanical brake assembly can act on the support rod over an entire range of motion of the door arrester. During a pivoting movement thus takes place a relative movement between the support rod and the mechanical brake assembly in the way that both components have consistent material contact. The mechanical brake arrangement preferably acts on a broad surface side.
Vorzugsweise ist die mechanische Bremsanordnung mittels eines Federglieds gegen zumindest eine der Oberflächenseiten vorgespannt. Diese Vorspannung setzt der Öffnungsbewegung einen Reibungswiderstand entgegen, der verhindert, dass die Fahrzeugtür zu stark an einer Endposition der Verschwenkung anschlägt. Hierbei kann das Federglied als eine Gasdruckfeder, eine Spiralfeder oder einem sonstigen Federtyp ausgebildet sein. Das Federglied ermöglicht eine zuverlässige, sichere und preisgünstige Vorspannung, welche den Reibungswiderstand zwischen der mechanischen Bremsanordnung und einer der Oberflächenseiten erzeugt, sodass der Verschwenkung der Fahrzeugtür ein Bremsmoment entgegengesetzt wird.Preferably, the mechanical brake assembly is biased by at least one of the surface sides by means of a spring member. This bias opposes the opening movement with a frictional resistance that prevents the vehicle door from striking too strongly at an end position of the pivoting. Here, the spring member may be formed as a gas spring, a coil spring or another type of spring his. The spring member allows a reliable, safe and inexpensive bias, which generates the frictional resistance between the mechanical brake assembly and one of the surface sides, so that the pivoting of the vehicle door is opposed to a braking torque.
Bevorzugt weist die Haltestange entlang ihrer Erstreckung zumindest auf einer der Oberflächenseiten eine Profilierung auf. Die Profilierung weist bspw. zwei erhöhte Abschnitte und zwei vertiefte Abschnitte auf. Alternativ ist die Profilierung ist durch drei erhöhte Abschnitte und durch drei vertiefte Abschnitte ausgebildet. Ebenso ist es bei Bedarf auch möglich, weitere vertiefte oder erhöhte Abschnitte vorzusehen. Insbesondere kann die Anzahl der vertieften und erhöhten Abschnitte auch ungleich sein. Vorteilhaft folgt hieraus, dass die Profilierung die Vorspannung durch das Federglied entlang der Erstreckung der Haltstange verändert, sodass unterschiedliche Bremsmoment erzeugt werden.The holding bar preferably has a profiling along its extension, at least on one of the surface sides. The profiling has, for example, two raised sections and two recessed sections. Alternatively, the profiling is formed by three raised sections and by three recessed sections. Likewise, if necessary, it is also possible to provide further recessed or raised sections. In particular, the number of recessed and raised sections can also be unequal. Advantageously follows from this that the profiling changes the bias of the spring member along the extension of the support rod, so that different braking torque can be generated.
Bevorzugt umfasst die Profilierung zumindest abschnittsweise einen Reib- oder Bremsbelag. Hierdurch wird erreicht, dass der Reibungskoeffizient zwischen der mechanischen Bremsanordnung und einer der Oberflächenseiten variabel ausgestaltet werden kann.Preferably, the profiling at least partially comprises a friction or brake lining. This ensures that the coefficient of friction between the mechanical brake assembly and one of the surface sides can be made variable.
Zweckmäßigerweise weist die Profilierung wenigstens eine Rastposition für die Fahrzeugtür auf. Hierdurch wird erreicht, dass die Fahrzeugtür an einem bevorzugten Öffnungswinkel festgestellt wird.The profiling expediently has at least one latching position for the vehicle door. This ensures that the vehicle door is detected at a preferred opening angle.
Gemäß einer weiteren bevorzugten Weiterbildung der Erfindung ist an die Haltestange und/oder das Haltegehäuse ein Lenkergetriebe angeschlossen, wobei zumindest ein Teil des Lenkergetriebes durch ein elektrisch antreibbares Blockiermittel arretierbar ist. Hierbei kann eine Schwenkbewegung der Fahrzeugtür durch eine Viergelenk ausgeführt werden, wobei das Viergelenk das Lenkergetriebe umfasst. Durch eine Arretierung des Lenkerbetriebes wird hierbei auch die Schwenkbewegung der Fahrzeugtür blockiert.According to a further preferred embodiment of the invention, a link mechanism is connected to the support rod and / or the holding housing, wherein at least a part of the link mechanism can be locked by an electrically driven blocking means. Here, a pivoting movement of the vehicle door can be performed by a four-bar link, wherein the four-bar linkage comprises the linkage gear. By locking the handlebar operation here is also the pivoting movement the vehicle door is blocked.
Gemäß einem Aspekt der Erfindung wird ein Verfahren zum Blockieren eines Türfeststellers angegeben, wobei eine elektromagnetisch wirkende Bremse eine von dem Türfeststeller angetriebene Scheibe blockiert. Vorteilhaft wird dadurch ermöglicht, dass die elektromagnetisch wirkende Bremse durch einen externen Sensor gesteuert werden kann und gleichbleibende Bremseigenschaften über ihre gesamte Lebensdauer aufweist.In accordance with one aspect of the invention, a method of locking a door arrester is disclosed wherein an electromagnetic brake blocks a disk driven by the door arrester. Advantageously, this makes it possible that the electromagnetically acting brake can be controlled by an external sensor and has constant braking properties over its entire life.
Bevorzugt löst ein Entfernungs- bzw. Hindernissensor die elektromagnetische Bremse aus. Hierdurch kann die Schwenkbewegung der Tür automatisch gestoppt werden, wenn die Schwenkbewegung der Tür ansonsten mit einem anderen Verkehrsteilnahme oder einem Gegenstand kollidieren würde.Preferably, a distance or obstacle sensor triggers the electromagnetic brake. As a result, the pivotal movement of the door can be stopped automatically if the pivoting movement of the door would otherwise collide with another traffic participation or an object.
In einer bevorzugten Weiterbildung löst ein Neigungssensor die elektromagnetisch wirkende Bremse aus. Dies verhindert ein unabsichtliches Verschwenken der Tür, falls sich das Fahrzeug an einem steilen Hang oder dergleichen befindet.In a preferred embodiment, an inclination sensor triggers the electromagnetically acting brake. This prevents unintentional pivoting of the door if the vehicle is on a steep slope or the like.
Vorzugsweise löst ein Unfall- bzw. Überschlagssensor die elektromagnetisch wirkende Bremse aus. Hierdurch bleibt die Fahrzeugtür selbst bei einem Unfall geschlossen, was eine Stabilität einer Fahrzeugkarossiere erhöht. Zudem kann der Unfall- bzw. Überschlagssensor zugleich einen Notruf absetzen, sodass beispielsweise eine Notrufzentrale über den Unfall informiert wird.Preferably, an accident or rollover sensor triggers the electromagnetically acting brake. As a result, the vehicle door remains closed even in the event of an accident, which increases the stability of a vehicle body shell. In addition, the accident or rollover sensor can also make an emergency call, so that, for example, an emergency call center is informed about the accident.
Weiter bevorzugt blockiert die elektromagnetisch wirkende Bremse die Tür in der Art einer Kindersicherung; dies ermöglicht vorteilhaft, dass die Kindersicherung nicht an der Tür selbst aktiviert bzw. gelöst werden muss, sondern beispielsweise von dem Fahrercockpit aus oder über ein Smartphone steuerbar ist.More preferably, the electromagnetically acting brake blocks the door in the manner of a child safety device; This advantageously makes it possible for the child safety device to not be activated or released on the door itself but to be controllable, for example, from the driver's cockpit or via a smartphone.

Mittels eines Gelenks ist die Fahrzeugtür 8 schwenkbar an den Türrahmen 6 angeschlossen, sodass eine Drehachse der Fahrzeugtür 8 zumindest parallel zu einer Drehachse eines Gelenks 12 ist. In dem Gelenk 12 ist ein Nietstift 16 aufgenommen, wobei der Nietstift 16 in einer zylinderförmigen Aussparung 18 einer Haltestange 20 des Türfeststellers 10 gelagert ist. Die Haltestange 20 ist hierbei an einem ersten Endbereich 21a der Haltestange 20 drehbar an das Gelenk 12 angeschlossen. Hierbei ist die Haltstange 20 in einer geraden Erstreckung ausgebildet und weist in ihrem Inneren einen Hohlraum 23 auf. Ein dem Gelenk 12 abgekehrtes Ende der Haltestange 20 bildet hierbei einen zweiten Endbereich 21b der Haltstange 20 aus.By means of a hinge, the
Der Türfeststeller 10 umfasst ferner ein Haltegehäuse 13, welches die Haltestange 20 umgibt und in welchem die Haltestange 20 entlang ihrer Erstreckung verschiebbar aufgenommen ist. Das Haltegehäuse 13 umfasst einen oberen Abschnitt 13a und einen unteren Abschnitt 13b, die durch zwei Gehäusenietstifte 34a, 34b miteinander fixiert sind. Sowohl der obere Abschnitt 13a als auch der untere Abschnitt 13b sind hierbei als Strangpressteile gefertigt. Zwischen dem oberen Abschnitt 13a und der Haltstange 20 und zwischen dem unteren Abschnitt 13b und der Haltestange 20 ist jeweils ein als holzylinderförmiger Abstandshalter 15a, 15b ausgebildetes Strangpressteil angeordnet. An einer dem Gelenk 12 zugehrten Seite sind an die holzylinderförmiger Abstandshalter 15a, 15b jeweils Befestigungsmittelaufnahmeabschnitte 17a, 17b ausgebildet. Die holzylinderförmiger Abstandshalter 15a, 15b sind vorgesehen, um den oberen Abschnitt 13a und den unteren Abschnitt 13b parallel von der Haltestange 20 zu beabstanden.The
Sowohl der obere Abschnitt 13a als auch der untere Abschnitt 13b des Haltegehäuses 13 umfassen (siehe
Entlang einer Erstreckungsrichtung von dem ersten Endbereich 21a zum zweiten Endbereich 21b der Haltestange 20 ist auf zwei gegenüberliegenden Oberflächenseiten 19a, 19b der Haltestange 20 jeweils ein Kunststoffbelag 22a, 22b ausgebildet. Die Oberflächenseiten 19a, 19b und die Kunststoffbeläge 22a, 22b sind hierbei dem zylinderförmigen Hohlraumabschnitt 33b des oberen Abschnitt 13a und des unteren Abschnitt 13b des Haltegehäuses 13 zugekehrt. Die Kunststoffbeläge 22a, 22b bzw. die Haltestange 20 weisen zudem auf beiden Oberflächenseiten 19a, 19b jeweils zwei Rastpositionen 24a, 24b auf, die als Vertiefungen 24a, b ausgebildet sind.Along a direction of extension from the
In dem zylinderförmigen Hohlraumabschnitt 33b des Haltegehäuses 13 ist eine mechanische Bremsanordnung 26 eingebracht, welche in einem geschlossenen Zustand des Türfeststellers 10 über bzw. unter dem ersten Endbereich 21a der Haltestange 20 angeordnet ist. Der Aufbau der mechanischen Bremsanordnung 26 ist in der Explosionszeichnung der
Zusätzlich ist an dem Haltegehäuse 13 im Bereich der oberen mechanischen Bremsanordnung 26a ein Anschlagdämpfer 36 angeschlossen, welcher Geräusche reduziert und ein angenehmeres Gefühl beim Öffnen der Fahrzeugtür durch einen Benutzer gewährleistet, indem der Anschlagdämpfer am Ende des Öffnungsvorgangs an starre Bauteile des zweiten Endbereichs 21b anschlägt.In addition, a
An einer dem Gelenk 12 abgewandten Seite der Schenkel 40a, 40b ist jeweils ein stiftförmiger Hohlraum 44a, 44b angebracht, wobei eine zentrale Achse durch die stiftförmigen Hohlräume 44a, 44b parallel zu der Drehachse des Gelenks 12 verläuft. Der stiftförmige Hohlraum 44a, 44b weist die Form eines Zylinders auf, wobei der Zylinder keinen geschlossenen Mantel aufweist, sodass ein Winkelbereich entlang der Erstreckung des zylinderförmigen Hohlraums 44a, 44b ausgespart ist und ein Napfabschnitt 46 mittels stiftförmiger Fortsätze 48a, 48b in die stiftförmigen Hohlräume 44a, 44b einsetzbar ist. Hierdurch ist der Napfabschnitt 46 stabil mit dem Haltegehäuse 13 verbunden. Abmessungen der stiftförmigen Fortsätze 48a, 48b sind hierbei so angepasst, dass diese passgenau in die stiftförmigen Hohlräume 44a, 44b einbringbar sind.At a side facing away from the joint 12 of the
Im Innenbereich des Napfabschnitts 46, welcher in
Eine Spindelstange 50 ist an ihrem dem Haltegehäuse 13 zugekehrten Ende in dem Hohlraum 23 aufgenommen und an ihrem dem Haltegehäuse 13 abgekehrten Ende in einem Rillenkugellager 70 gelagert. An dem zweiten Endbereich 21b der Haltestange 20 ist die Spindelstange 50 hierbei drehbar in einer Spindelmutter 52 angeordnet, wobei die Spindelmutter 52 drehfest an den zweiten Endbereich 21b der Haltestange 20 angeschlossen ist. Entlang einer Richtung von dem ersten Endbereich 21a zum zweiten Endbereich 21b der Haltestange 13 ist im geschlossenen Zustand der Fahrzeugtür 8 hinter der Spindelmutter 52 die permanentmagnetische Ankerscheibe 56 angeordnet, welche drehfest mit der Spindelstange 50 verbunden ist.A
Durch den Schließvorgang bzw. den Öffnungsvorgang der Fahrzeugtür 8 wird die Spindelstange 50 durch die Spindelmutter 52 in eine Rotationsbewegung versetzt, sodass die permanentmagnetische Ankerscheibe 56 mit der gleichen Rotationsgeschwindigkeit wie die Spindelstange 50 rotiert. Entlang der Erstreckungsrichtung der Spindelstange 50 ist hierbei der Elektromagnet 62 angeordnet, wobei der Elektromagnet 62 eine zentrale zylinderförmige Aussparung 63 auf, welche berührungslos von der Spindelstange 50 durchsetzt ist. Der Elektromagnet ist hierbei mittels seiner Lagerung in dem Magnetgehäuse 64, welches seinerseits wiederum in dem Napfabschnitt 46 aufgenommen ist, relativ zum Haltegehäuse 13 starr in seiner Position gehalten, sodass der Elektromagnet 62 nicht mit der Spindelstange 50 in einem Materialkontakt steht. Zwischen der permanentmagnetische Ankerscheibe 56 und dem Elektromagneten 62 ist eine Anlaufscheibe 58 an der Spindelstange 50 angebracht. Die Anlaufscheibe 58 stellt hierbei einen Reibungsschutz zwischen dem Elektromagneten 62 und permanentmagnetische Ankerscheibe 56 dar. Zudem stellt die Anlaufscheibe 58 sicher, dass über die gesamte Lebensdauer des Türfeststellers 10 eine axiale Führungsgenauigkeit gewährleistet ist. An einer dem Gelenk 12 abgewandten Seite des Napfabschnitts 46 ist das Rillenkugellager 70 zur drehbaren Lagerung der Spindelstange 50 in dem Napfabschnitt 46 vorgesehen.By the closing operation or the opening operation of the
Der Elektromagnet 62 und die permanentmagnetische Ankerscheibe 56 bilden zusammen den sogenannten elektromagnetischer Einwicklungsdrehsteller 60 aus, sodass die Bestromung des Elektromagneten 62, welche von der Sensorik angesteuert wird, dazu führt, dass sich die Ankerscheibe 56 maximal noch um 45° drehen kann, bevor sie durch eine elektromagnetische Kraftwirkung festgestellt wird.The
Der Öffnungsvorgang der Fahrzeugtür kann nun mittels der mechanischen Bremsanordnung 26 gestoppt werden, indem die Haltestange 20 entlang der mechanischen Bremsanordnung entlang bewegt und die mechanische Bremsanordnung 26 den Türfeststeller 10 an den bevorzugten Rastpositionen 24a, 24b arretiert.The opening operation of the vehicle door can now be stopped by means of the
Die zweite Rastposition 24b entspricht hierbei einer vollständig geöffneten Fahrzeugtür, wobei der Anschlagdämpfer 36 hierbei an dem zweiten Endbereich 21b der Haltestange 20 anschlägt.In this case, the
Detektiert die Sensorik, dass ein anderer Verkehrsteilnehmer oder ein beliebiger Gegenstand während des Öffnungsvorgangs mit der Fahrzeugtür kollidieren würde, sendet die Sensorik ein Signal, welches den Elektromagneten 62 bestromt. Die Bestromung des Elektromagneten 62 führt dazu, dass das die permanentmagnetische Ankerscheibe 56 höchsten weitere 45° rotiert, da die zweipolige permanentmagnetische Ankerscheibe 56 durch den vierpoligen Elektromagneten 62 berührungslos durch elektromagnetische Kräfte festgestellt wird. Hierdurch wird zugleich die Rotationsbewegung der Spindelstange 50, an welche die permanentmagnetische Ankerscheibe 56 drehfest angeschlossen ist, gestoppt, sodass die axiale Verlagerung der Haltestange 20 automatische gestoppt wird und der Öffnungs- bzw. Schließvorgang Fahrzeugtür 8 durch den Türfeststeller 10 arretiert ist. Je größer die Anzahl der Windungen der Spindelstange 50 pro Längeneinheit ist, desto genauer kann die Fahrzeugtür 8 festgestellt werden.If the sensors detect that another road user or any object would collide with the vehicle door during the opening process, the sensor system sends a signal which energizes the
Ferner kann die Sensorik so ausgebildet sein, dass der Türfeststeller 10 auch bei einem Schließvorgang durch die Bestromung des Elektromagneten 62 arretiert wird. Beispielsweise könnte die Sensorik detektieren, falls ein Körperteil wie etwa ein Finger bei einem Fortsetzen des Schließvorgangs zwischen Fahrzeugtür 8 und Türrahmen 6 eingeklemmt werden würde.Furthermore, the sensor system can be designed so that the
Die Erfindung ist vorstehend anhand eines bevorzugten Ausführungsbeispiels erläutert worden, bei dem die Feststellung des Türfeststellers durch eine Spindelstange 50 erfolgt, die in einem Hohlraum 23 der Haltestange 20 axial verschiebbar aufgenommen ist, wobei eine Spindelmutter 52 in der Haltestange 20 angeordnet ist, die die Spindelstange 50 bei Relativbewegung der Haltestange 20 zu dem Haltegehäuse 13 in Rotation versetzt, und wobei eine an die Spindelstange 50 angeschlossene Scheibe 58 mitgedreht wird, welche durch ein elektrisch antreibbares Blockiermittel 62 berührungslos arretierbar ist. Es versteht sich, dass die Scheibe 58 auch berührend arretiert werden kann, beispielsweise wenn das Blockiermittel einen Bremsbelag aufweist, der gegen eine Stirnfläche der Scheibe 58 bei Auslösung in Anlage gelangt. Ist das Blockiermittel hierzu elektrisch antreibbar ausgebildet, kann dies in Form eines elektromagnetischen Aktors erfolgen, der einen mit einem Anker des Aktors verbundenen Bremsbelag in Richtung auf die Scheibe 58 vorschiebt, beispielsweise nach Art eines axial verlagerbaren Ankers eines Elektromagneten. In diesem Fall gelangt der Bremsbelag gegen die eine große Oberfläche bietende Stirnfläche der rotierenden Scheibe in Anlage und blockiert diese. Ergänzend zu dem Bremsbelag können noch Formschlussmittel axial aus dem vorgeschobenen Teil vorstehen, die einen formschlüssigen Eingriff ermöglichen; hierzu weist die Scheibe dann korrespondierende Aussparungen auf, in die die Vorsprünge eindringen können und die ein Weiterdrehen der Scheibe verhindern. Um einen verbesserten Formschluss zu erreichen, kann die Scheibe auch mit Erhebungen und Vertiefungen ausgestattet sein, die mit Erhebungen und Vertiefungen des Bremsbelags korrespondieren, sodass ein gegenseitiges Verdrehen nach Erreichen einer Bremsposition verhindert ist. Hierdurch wird vorteilhaft ein besonders kleiner weiterer Drehwinkel der Scheibe erreicht, sodass ein sehr präzises Anfahren der Blockiermittel zu einem sehr schnellen Stoppen der Haltestange 20 führt.The invention has been explained above with reference to a preferred embodiment in which the determination of the door arrester by a
Die Erfindung ist vorstehend anhand eines Ausführungsbeispiels beschrieben worden, bei dem die Relativbewegung von Haltestange 20 und Haltegehäuse 13 eine Rotation der Scheibe 58 bewirkt hat, die dann durch eine Spule berührungslos arretiert wurde. Es versteht sich, dass die Relativbewegung von Haltestange 20 und Haltegehäuse 13 auch durch ein Lenkergetriebe, dessen Lenker mit dem einen oder dem anderen Teil miteinander gekoppelt sind, darstellbar ist, und dass zumindest ein Teil des Lenkergetriebes durch ein elektrisch antreibbares Blockiermittel arretierbar ist. Hierzu kann das Lenkergetriebe vergleichbar dem beschriebenen Ausführungsbeispiel eine Scheibe, oder einen Fortsatz eines Lenkers in Rotationsbewegung versetzen und durch eine Spule magnetisch arretieren. Das Lenkergetriebe kann zweidimensional oder dreidimensional ausgebildet sein und koppelt vorzugsweise den zweiten Endbereich 21b der
Haltestange 20 und das Haltegehäuse 13, wobei hierdurch vorteilhaft eine langgestreckte Erstreckung der Haltestange 20 nicht erforderlich ist, sondern diese eine aus der Praxis bekannte gekrümmte Form aufweisen kann. Ferner sind die Lenker des Lenkergetriebes in einer zu der Ebene der Haltestange im Wesentlichen parallelen Ebene verschwenkbar, sodass die Schwenkbewegung der Lenker in der Fahrzeugtür 8 ohne Behinderung der Haltestange 20 erfolgen kann. Ein umfangreiches Gehäuse mit einem Napf 46 und Schenkel 40a, 40b sind dann nicht mehr erforderlich. Es ist möglich, das Teil des Lenkergetriebes, das durch ein elektrisch antreibbares Blockiermittel arretierbar ist, berührungslos zu arretieren wie vorstehend für die Scheibe 58 beschrieben; vorzugsweise wird jedoch eine berührende Arretierung erfolgen, beispielsweise über einen durch ein Magnetventil betätigten Bremsbelag. Das von dem Blockiermittel arretierbare Teil des Lenkergetriebes kann auch als Teil einer Kolbenzylinderanordnung oder einer Spindelmutter-Spindelstangen-Anordnung ausgeführt sein.The invention has been described above with reference to an embodiment in which the relative movement of the holding
