Definitions
- the invention relates to a motor vehicle door lock, with a locking mechanism, at least one locking lever, further at least one motor drive for the locking lever, and with a clutch lever which "unlocked” in its position connects a handle with the locking mechanism to the opening and in its position "locked” the handle separates from the locking mechanism.
- a motor vehicle door lock of the embodiment described above is described in DE 102 47 842 A1.
- a central locking arrangement and a clutch arrangement are realized, wherein the clutch assembly is equipped with a quick release lever.
- the arrangement of the lock mechanism is taken overall so that an adjustment of the central locking arrangement from the locked to the unlocked state initially causes an adjustment of the coupling arrangement from the locked to the unlocked state and then an adjustment of an mecanicverriegelungsele- ment from the locked to the unlocked state.
- the motor drive has an actuating element, which brings a locking lever and the aforementioned quick release lever respectively in an unlocked and in a locked state.
- the single control element has two actuating arrangements which are coupled on the one hand to the locking lever and on the other hand to the quick release lever.
- the locking lever and the quick release lever are pivotally mounted about the same axis in an associated housing.
- the quick-release lever and also the locking lever is rotated radially to its adjustment, which with Disadvantages associated with the reliability.
- the known motor vehicle door lock is limited by the chosen topology of the possible variations ago and has a relatively complicated structure.
- EP 1 288 408 A2 likewise describes a motor vehicle door lock with a quick-release function. This requirement is well known and not limiting in motor vehicle door closures equipped with a keyless entry system. Because here it is necessary, especially with additional use of an anti-theft device to set the time required from the initiation of the opening process to the ability to open the equipped with the door locks motor vehicle doors as low as possible. Usually, here time periods of less than 40 msec. required to avoid any restriction of comfort.
- the procedure is such that the locking mechanism is connected to the locking lever via the quick-release lever.
- the quick release lever releases the locking mechanism in the course of the quick release by means of the motor drive, essentially independent of the position of the locking lever. That is, the locking lever and the Schnellentriegelungshebel be operated independently, resulting in a significant design effort.
- EP 1 226 325 B1 proposes a motor vehicle door lock with a quick-release function, in which a locking lever engaged with the locking lever is provided for quick unlocking.
- the locking lever is separated from the locking lever by means of the motor drive in the course of the quick release, so that the locking mechanism lever can be transferred to its unlocked position.
- the invention aims to provide a total remedy.
- the invention is based on the technical problem of further developing a motor vehicle door lock of the embodiment described at the beginning in such a way that a simple and cost-effective solution exists, with at the same time achieving increased functional reliability.
- a generic motor vehicle door lock in the invention is characterized in that the motor drive operates directly on both the locking lever and on the clutch lever to "unlocked” this at least in each case in their functional position and / or " locked “and to have an actuator with each locking lever actuator assembly and clutch lever actuator assembly.
- the clutch lever for capturing its position "unlocked" by means of the clutch lever actuator assembly can be adjusted linearly against spring force.
- the clutch lever can otherwise undergo an adjustment, for example, radially or rotationally.
- the clutch lever and the locking lever are structurally separated from each other and an additional quick release lever according to DE 102 47 842 A1 is eliminated.
- the structure is simple, compact and inexpensive, because fewer moving levers are realized.
- the locking lever can be pivoted regularly about an axis, whereas the clutch lever preferably a linear adjustment in bei- For example, learns linear guides against a housing.
- This is in detail at the locking lever to a central locking lever, which is equipped as usual with a fork receptacle for one or more engaging therein control cam.
- These control cams are a component or form the locking lever actuating arrangement. With their help, the locking lever at least the positions "unlocked” and "locked” occupy.
- the locking lever or central locking lever can be additionally transferred to the position "anti-theft" in which all the actuators (essentially inside lever and external operating lever) go empty or ineffective and in addition unlocking from the inside, for example by pulling a mecanicverriegelungsknopfes, not possible is. That is, the entire vehicle door lock can be basically transferred to the position "theft-proof” using the locking chain.
- time sequence can also be designed differently by the clutch lever and the locking lever more or less simultaneously take their position "unlocked”. In general, however, one will make the interpretation so that the clutch lever takes the position "unlocked” first and the locking lever follows him.
- the one guide cam is guided in the housing for the motor vehicle door lock and thus operates as a housing guide cam.
- the other guide cam regularly learns a guide in the locking lever and can therefore be referred to as a locking lever guide cam.
- the clutch lever in its "unlocked" position ensures a continuous mechanical connection to the handle, an L-shaped guide slot is provided in the housing for the housing guide cam.
- an additional spring may be provided which biases the clutch lever in the direction of its rest position. In this rest position - and usually only in this - the locking lever is able to take the positions "unlocked” and "locked” can.
- a motor vehicle door lock which is characterized by a simple structure and a cost-effective realization.
- this is due to the fact that no special quick-release facilities are provided, but almost always existing clutch lever as it assumes the function of the quick release lever.
- the motor vehicle door lock according to the invention can be easily adapted to different circumstances and is characterized by special reliability.
- the actuating element of the motorized drive can be made split and on the one hand can carry the locking lever actuating arrangement and, on the other hand, the clutch lever actuating arrangement. Both parts of the control element can be coupled together by a (form-fitting) operative connection and move together or separately from a motor or electric motor of the motor drive.
- Fig. 5 is a rear view of the motor vehicle door lock and Fig. 6 shows the motor vehicle door lock according to the invention in its arrangement in the motor vehicle door.
- a motor vehicle door lock 19 which has a not explicitly shown locking mechanism of pawl and rotary latch. On this locking mechanism operates in a known manner, a release lever which lifts the pawl, so that the rotary latch spring-assisted release a locking pin.
- the release lever acts on the one hand with a locking lever 1 and on the other hand with a clutch lever 2 together, which is “unlocked” in its functional position with a handle 3 in mechanical operative connection.
- the position "unlocked” of the clutch lever 2 is shown in Figs. 2, 3 and 4 and corresponds to a position A of a guide cam or housing guide cam 4, while in Fig. 1, its position "locked” is shown.
- the clutch lever 2 has yet another guide cam 5, namely the lock lever guide cam 5.
- the clutch lever 2 is guided linearly, between its two Positions “unlocked” (position A) and “locked” (position B).
- position A the clutch lever 2 is guided linearly, between its two Positions “unlocked” (position A) and “locked” (position B).
- position B the clutch lever 2 is guided in a housing 6, more precisely in an L-shaped guide contour or guide slot 7 of the housing 6.
- the housing guide cam 4 in the "locked” position (position B) Pivoting movements of the clutch lever 2 to a coincident with the locking lever guide cam 5 axis of rotation not (see, the dot-dash line illustration in Fig. 2 and the associated double arrow).
- the locking lever guide cam 5 is guided in a recess or longitudinal recess 8 in the locking lever or central locking lever 1.
- the locking lever guide cam 5 of the clutch lever 2 moves during the transition from the position “locked” in the position "unlocked” from a foot-side to the head end of the recess 8 in the locking lever 1. This is true as long as the locking lever 1 in his position "locked” is, which is shown in Figs. 1 and 2.
- the motor drive 10, 11, 12 is composed of an electric motor 10, an adjusting element 11 or an adjusting disk 11 rotatable about an axis 13 and finally one or more control cams 12 arranged on the adjusting disk 11.
- two control cams 12 are realized on the one side of the adjusting disk 11, as best seen in viewing the rear view of FIG. 5.
- the control cams 12 dive into a fork receptacle 14 of the locking lever or central locking lever 1, in order to transfer it at least into the positions "unlocked” (compare FIGS. 3 and 4) or "locked” (compare FIGS. 1 and 2).
- the control cams 12 function as a latch actuating arrangement 12 of the control element 11 and consequently operate on the locking lever 1.
- the adjusting element or adjusting disk 11 is equipped with a clutch lever actuating arrangement 15 which can be found in the context of the exemplary embodiment and not restricting on the other side of the adjusting element 11 or the adjusting disk 11 in comparison to the locking lever actuating arrangement 12.
- the clutch lever actuating assembly 15 has a control contour 15, by means of which the clutch lever 2 is transferred from its "locked” position in FIG. 1 to the "unlocked” position according to FIG. 2. This makes a comparison of Figs. 1 and 2 clearly.
- the adjusting element or the adjusting disk 11 rotates in the counterclockwise direction, specifically by about a quarter turn (cf., the transition from Fig. 1 to Fig. 2).
- the clutch lever 2 is adjusted linearly against spring force, which is exerted by a leg spring 16 on the clutch lever 2.
- the spring or leg spring 16 which is arranged on the locking lever 1, is supported with one leg 16a on a stop 17 of the locking lever 1, while its other leg 16b supports the locking lever guide cam guided in the recess 8 of the locking lever 1 5 biased toward the position "locked" of the clutch lever 2.
- the clutch lever 2 is pulled pulling and not sliding with the help of the control contour 15.
- the clutch lever 2 is L-shaped with Betrelinshebelarm 2a and Verstellhebelarm 2b in the context of the embodiment and not restrictive.
- the actuating lever arm 2a carries the locking lever guide cam 5, while the adjusting lever arm 2b engages the adjusting lever actuating arrangement 15 or the control contour 15 there.
- the clutch lever 2 is transferred in time before the locking lever 1 in its "unlocked” position.
- the desired quick release can be represented, which corresponds to the fact that there is a mechanical connection between the handle 3 and the locking mechanism, not shown, with the interposition of the coupling lever 2, even if the locking lever or central locking lever 1 not yet in its position "locked” is located. This shortens the total unlocking time.
- Fig. 3 shows a variant in such a way that an additional spring 18 is provided, which biases the clutch lever 2 in the direction of an actuating rest position. That is, as long as the handle 3 is not pulling or whatever, the spring in question ensures that the clutch lever 2 occupies the functional position shown. As a result, the locking lever 1 is able to easily assume its positions “unlocked” and "locked”.
- clutch lever actuator assembly 15 and / or the locking actuator assembly 12 may optionally operate on intermediate lever on the one hand the clutch lever 2 and on the other hand, the locking lever 1.
