Description

Adjusting system for a vehicle lamp, vehicle lamp and motor vehicle

Technical Field

The invention relates to an adjustment system for a vehicle lamp, a vehicle lamp and a motor vehicle.

Background

In a vehicle, it is generally necessary to adjust the position of a light emitting module of a vehicle lamp about a horizontal axis or a vertical axis in order to make a beam irradiation position of light emitted from the light emitting module meet a regulatory requirement. For this purpose, the actuator acts on the light module of the vehicle lamp, in particular on a support body of the light module, via the adjusting element, so that the light module can be pivoted about the respective axis, thereby adjusting the light module. The adjusting element is coupled, for example by means of a ball and socket joint, to a support body arranged on the housing of the light module, so that the operation of the actuator is converted via the adjusting element into a pivoting movement of the light module.

Disclosure of Invention

The invention aims to provide an adjusting system for a vehicle lamp, which can improve the universality of the adjusting system and reduce the cost.

According to the invention, a regulating system is proposed, which has: a support; a drive member; an adjustment member for acting on the vehicle lamp to move the vehicle lamp; a conducting structure arranged between the driving member and the adjusting member to conduct the movement of the driving member to the adjusting member. The drive element, the adjusting element and the conducting structure are held on a carrier, the conducting structure being configured such that its length can be adjusted. By means of the length-adjustable conducting structure, the same adjusting system can be used for different vehicle lamps while keeping the other structures of the adjusting system substantially unchanged. The adjusting system can meet the requirements of different transmission lengths, the applicability is wide, the universality is strong, and a large amount of development cost and time can be saved.

According to some embodiments, the conductive structure may be constituted by a first conductive rod having a first engagement section engaging with the driving member and a first docking section, and a second conductive rod having a second engagement section engaging with the adjusting member and a second docking section, the first and second docking sections being docked to each other to form a form-fitting and length-variable force-transfer connection.

The first and second docking sections are complementary to each other in cross-sectional shape at the joint in order to achieve a force-fitting connection. The complementary overall cross-sectional shape may be, for example, circular, etc. Thus, after the first and second docking sections of the conductive rod are docked, the length of the formed conductive structure may vary within a predetermined range in the axial direction, however the force transmission properties of the conductive structure are not adversely affected.

In one embodiment, the respective butt sections of the first or second conductor bar are provided in pairs diametrically opposite from each other with notches starting from the end side and extending in the axial direction, whereby a catch is formed between adjacent notches. When the butt joint is carried out, the claw of the first conducting rod is inserted into the notch of the second conducting rod, the claw of the second conducting rod is accommodated in the notch of the first conducting rod, and therefore the force transmission connection in a shape matching mode is achieved, wherein the claw of one conducting rod can move axially within a preset range in the notch of the other conducting rod, and therefore the axial length is adjusted. Preferably, the cross-sections of the jaws and notches are the same.

In a further embodiment, the first docking section of the first conductive rod has a polygonal cross section, and the second docking section of the second conductive rod has a polygonal opening in cross section, the cross section of the opening matching the polygonal cross section of the first docking section. In this case, the first docking section of the first conductive rod is inserted into the second docking section of the second conductive rod, the insertion depth being adjustable within a predetermined range, thereby resulting in conductive rods of different lengths. Here, the cross section may be a cross, a triangle, a quadrangle, or a spline, etc.

It should be noted that any suitable cross-sectional shape is conceivable for the first and second docking sections, as long as a form-fitting force-transmitting connection is possible and the docking length can be adjusted in the axial direction.

The first and second conductor bars can be embodied in one piece, for example injection-molded from plastic. In the case where the engagement locations for the respective mating members of the first conductive rod and the second conductive rod are the same, the first conductive rod and the second conductive rod may be identically implemented, thereby enabling further cost reduction.

According to some embodiments, the conductive structure is constituted by a first conductive rod having a first engagement section engaged with the driving member and a first docking section, and a second conductive rod having a second engagement section engaged with the adjusting member and a second docking section, the first and second docking sections being docked to each other by a flexible force-transmitting member. Here, a "flexible force transmission element" can be understood in this way: it can be deformed so as to vary the linear distance between its two ends, but the deformed force-transmitting member can still accomplish the transmission of force from the first conducting rod to the second conducting rod. The flexible force transmission element can be embodied, for example, as a metal hose, the two ends of which are fixedly connected to the abutting sections of the first and second conductor bars, respectively.

According to some embodiments, the conducting structure and the drive element and/or the adjusting element are force-fit connected to each other via a toothing. The engagement section of the conductor bar of the conductor structure is provided with a toothing. The transmission rod and the drive element and/or the adjusting element can be arranged coaxially or at an angle. In the case of an angled arrangement, the toothing can be a conical toothing and is therefore suitable for the case of a non-linear power flow direction. In the case of identical teeth of the drive element and the adjusting element, the transmission rod of the transmission structure can be embodied identically.

In order to hold the conducting structure on the holder, the holder has at least one pair of first holding portions for the conducting structure to determine the axial length of the conducting structure. The holder also has at least one pair of second holding portions for the conducting structure to prevent the conducting structure from moving in a direction transverse to its axial direction. The retaining portion does not restrict rotational movement of the mounted conducting structure. For this purpose, at least some sections of the conductive structure have a circular cross section.

Of course, it is also possible to provide a holder on the holder which is capable of simultaneously determining the axial length of the conducting structure and preventing the conducting structure from moving in a direction transverse to its axial direction. The holding part may be in the form of a clamping pair, have a cylindrical surface sheet-like inner surface which is in contact with a section of the conducting structure having a cylindrical surface, which section may be a groove in which the holding part is accommodated and is not axially movable within the groove, wherein the holding part is elastically deformable when accommodated in the groove.

The first coupling section and the first docking section of the first transfer bar may also be implemented separately and then connected together, for example by gluing, welding, screwing or other means.

The invention also aims to propose a vehicle lamp with an adjustment system for a vehicle lamp as described above.

The object of the invention is also to propose a vehicle, in particular a motor vehicle, having a lamp as described above.

Detailed Description

Embodiments of the present invention are exemplarily described below. As will be realized by those skilled in the art, the illustrated embodiments can be modified in various different ways, without departing from the spirit of the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive. In the following, the same reference numerals generally denote functionally identical elements.

Fig. 1 shows an adjusting system 1 for a vehicle lamp according to the invention, having a drive element 40, on which drive element 40 an actuator, not shown, acts. The actuator is for example an electric motor, the output shaft of which acts for example in a recess of the drive member 40 to transmit the rotational movement of the output shaft of the electric motor to the drive member 40. The actuator may also be a manual adjustment tool, such as a wrench, which is inserted into a polygonal recess of the driving member 40, the rotational movement of the driving member 40 in the direction T being achieved by manually rotating the adjustment tool. The adjusting system 1 also has an adjusting element 50 which can convert a rotary movement into a horizontal movement, in particular into a horizontal movement of an adjusting lever 52 connected to the housing of the vehicle lamp, for example by means of a ball-and-socket joint, thereby effecting a pivoting movement of the vehicle lamp about a corresponding axis in order to adjust the angle of the vehicle lamp. The manner of functioning of the adjustment member 50 is known in the art and will not be described in detail here. Fig. 1 also shows a conducting structure 60 arranged between the drive element 40 and the adjusting element 50, which conducts the movement of the drive element 40 to the adjusting element 50, wherein the conducting structure 60 has conducting

rods

20, 30 and a holder 10 holding the conducting rods. The transmission rod is formed by a first transmission rod 20 and a second transmission rod 30, the first transmission rod 20 having a first engagement section 21 and a first docking section 22 which are engaged with the drive element 40, for example, by toothing, and the second transmission rod 30 having a second engagement section 31 and a second docking section 32 which are engaged with the adjusting element 50, for example, by toothing, wherein the first docking section 22 and the second docking section 32 are docked in the axial direction of the transmission rod to form a form-fitting force-fitting docking, so that a transmission rod of variable length is formed.

As can be seen in fig. 1, the conducting structure 60 is arranged at an angle, for example 90 degrees, to the driving element 40 and the adjusting element 50. Of course, the conducting structure 60 may also be arranged linearly with at least one of the driving element 40 and the adjusting element 50.

Fig. 2 shows a perspective view of a first one of the conductive rods 20 of the conductive structure 60. The structure of the second conductive bar 30 may be implemented similarly to the structure of the first conductive bar 20.

As can be seen from fig. 2, the first transmission rod 20 has, from left to right, a first engagement section 21, a first connection 23, a first recess 24, a first stop 25 and a first docking section 26. As can also be seen from fig. 2, the first docking sections 26 are provided in pairs diametrically opposite from each other with notches 262 starting from their ends and extending in the axial direction, whereby between adjacent said notches 262 a pawl 261 is formed. Since the structure of the second conductive rod 30 is implemented in a structure similar to the first conductive rod 20, the second mating section of the second conductive rod 30 is also provided with notches and claws. Here, the cross-sectional shape of the notch 262 of the first docking section 26 of the first conductive rod 20 matches the cross-sectional shape of the claw of the second docking section of the second conductive rod 30, and the cross-sectional shape of the claw 261 of the first docking section 26 of the first conductive rod 20 matches the cross-sectional shape of the notch of the second docking section of the second conductive rod 30. When mated, the notches and catches of the respective conductor bars engage each other, thereby forming a form-fitting force-transmitting connection, wherein the first conductor bar 20 and the second conductor bar 30 are movable relative to each other in the axial direction within a predetermined range, thereby forming a variable-length conductor bar. The length determination of the conductive rods will be described in detail below.

FIG. 3 shows a cross-sectional view of first mating section 26 of first transfer bar 20 of FIG. 2 at position A-A, from which the pairs of jaws 261 and notches 262 can be seen. Preferably, the pawl 261 and the notch 262 are identical in cross-section. In this case, if the engaging sections of the respective conductive bars are also implemented identically, the abutting sections of the first conductive bar 20 and the second conductive bar 30 can be implemented at least identically, whereby costs can be reduced to a large extent. When both the drive element 40 and the adjusting element 50 are provided with toothed engagement sections and they are embodied identically, the first and

second transmission rods

20, 30 can be embodied identically, whereby the number of parts can be reduced.

It is also conceivable here that, in addition to the two claws and notches shown in fig. 3, a further even number of claws and notches can be provided, wherein the claws and notches are arranged alternately, the cross-sectional shapes of the claws and notches of different conductor bars being adapted correspondingly to one another, more precisely complementary to one another, with the proviso that structural strength is satisfied.

Fig. 4 shows a perspective view of the stand 10. The holder 10 has a receiving portion 11 for receiving the driving member 40. An opening 13 is provided in the receptacle 11, and the drive element 40 is rotatably but non-displaceably arranged in the opening 13 in the axial direction of the opening. A first retaining portion, for example a pair of ribs 16, is provided on the inside of another section of the holder 10 adjacent to the receptacle 11. The first conductive bar and the second conductive bar have grooves 24, respectively. In the installed position, the rib 16 is inserted into the recess 24, and both sides of the rib 16 each come into contact with a respective side of the recess, thereby setting the length of the conductor bar, which is composed of the first conductor bar and the second conductor bar. The holder 10 may also be provided on the inside with at least one pair of second holders, for example grips 15, which act on the outside of the first conductor bar 20 and/or the second conductor bar 30 to prevent the first conductor bar 20 and the second conductor bar 30 from moving in a direction transverse to the axial direction, but do not prevent the rotation of the conductor bars, for which purpose the contact surfaces of the conductor bars with the second holders are cylindrical patches.

When the first and second conduction bars 20 and 30 are butted, the butted conduction bars are pushed into the grip 15 and simultaneously the corresponding grooves are brought into contact with the fins, whereby a desired length of the conduction mechanism is set by a predetermined fin pitch and the conduction mechanism can be prevented from falling off the rack 10.

The bracket 10 may be a part of the vehicle body or be made up of multiple parts. In the case of a multi-part support, an opening 14 can be provided in the support and the support can be fastened to the vehicle body, for example by means of a screw passing through this opening 14, in order to achieve the support function.

Fig. 5 shows a perspective illustration of a further exemplary embodiment of the adjusting system according to the invention for a vehicle lamp according to fig. 1. It can be seen here that the ribs 16 of the holder 10 of fig. 5 have a greater spacing relative to one another than in the case shown in fig. 1. However, in this case, with the same conductive rods, the respective motion-conducting function can be achieved by merely moving the conductive rods relative to one another over a distance in the axial direction. It can be seen that the end side of one conductive rod is spaced apart relative to the axial end side of the notch of the other conductive rod.

The components of the adjustment system shown are preferably made of a plastic material.

Fig. 6a-6c show cross-sectional illustrations of other embodiments of the first and second conductive bars, in particular the butt sections of the conductive bars. For example, the docking section of the first conductive rod may have a polygonal cross-section, such as a quadrilateral (fig. 6a), a triangular (fig. 6b) and a spline (fig. 6c), while the second conductive rod has a central opening, the cross-section of which matches the cross-sectional shape of the docking section of the first conductive rod, so that upon docking, the docking section of the first conductive rod may be inserted into the docking section of the second conductive rod having the opening, and the docked first and second conductive rods may be moved in the axial direction relative to each other, thereby achieving a variable length and fulfilling a force transfer function.

Fig. 7 shows a further schematic representation of the conduction means of the adjusting system for a vehicle lamp according to the invention. The

transmission rods

20, 30 of the transmission mechanism are connected together by a flexible force transmission element. The flexible force transmission element can be deformed when the

transmission rods

20, 30 are adjusted, for example, the axial length is changed in the axial direction, thereby setting the length of the transmission mechanism.

The present invention is not limited to the above configuration, and various other modifications may be adopted. While the invention has been described with respect to a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that other embodiments can be devised which do not depart from the scope of the invention as disclosed herein. Accordingly, the scope of the invention should be limited only by the attached claims.
