The ball head is arranged at the first end of the mounting seat and is used to cooperate with the ball head seat arranged in the lamp housing to realize the function of a movable joint, thereby realizing the adjustment of the light output angle of the vehicle lamp. The adjusting shaft is arranged at the second end of the mounting seat, and a first adjusting thread is arranged on the adjusting shaft; the adjusting cylinder is sleeved on the adjusting shaft, and a second adjusting thread meshing with the first adjusting thread is arranged on the inner wall of the adjusting cylinder, and the adjusting shaft can be driven to move axially by rotating the adjusting cylinder, thereby driving the ball head to move, and a first transmission jump tooth is arranged on the outer wall of the adjusting cylinder; the first transmission member is sleeved on the adjusting shaft A second transmission jumping tooth is arranged on the inner wall of the adjusting cylinder and the first end of the first transmission member, and the second transmission jumping tooth meshes with the first transmission jumping tooth to realize transmission.

DETAILED DESCRIPTION

[0045] The core of the present invention is to disclose a dimming system to reduce the risk of damage to the parts of the headlights during the process of adjusting the angle of the headlights.

[0046] Another core of the present invention is to disclose a vehicle lamp including the dimming system.

[0047] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0048] Combination Figure 1-Figure 13 The dimming system disclosed in the present invention includes a sliding bracket 100, an adjusting cylinder 200, a first transmission member 300 and a second transmission member 500. The sliding bracket 100 includes a mounting seat 120, a ball head 110 and an adjusting shaft 130. The ball head 110 is arranged at the first end of the mounting seat 120, and is used to cooperate with the ball head seat arranged in the lamp housing to realize the function of a movable joint, thereby realizing the adjustment of the light output angle of the vehicle lamp. The adjusting shaft 130 is arranged at the second end of the mounting seat 120, and a first adjusting thread 131 is arranged on the adjusting shaft 130; the adjusting cylinder 200 is sleeved on the adjusting shaft 130, and a second adjusting thread 210 meshing with the first adjusting thread 131 is arranged on the inner wall of the adjusting cylinder 200. The adjusting shaft 130 can be driven to move axially by rotating the adjusting cylinder 200, thereby driving the ball head 110 to move. A first transmission jump tooth 220 is arranged on the outer wall of the adjusting cylinder 200; the first transmission The member 300 is sleeved on the adjusting cylinder 200, and a second transmission jumping tooth 310 is provided on the inner wall of the first end of the first transmission member 300, and the second transmission jumping tooth 310 is meshed with the first transmission jumping tooth 220 to realize transmission. At the same time, a deformation release groove is provided on at least one of the adjusting cylinder 200 and the first transmission member 300, and the deformation release groove is used for allowing the adjusting cylinder 200 and / or the first transmission member 300 to undergo elastic deformation, so that the second transmission jumping tooth 310 can jump relative to the first transmission jumping tooth 220, thereby realizing relative rotation between the adjusting cylinder 200 and the first transmission member 300; a first transmission bevel tooth 320 is provided on the outer wall of the second end of the first transmission member 300, and a second transmission bevel tooth 510 is provided on the first end of the second transmission member 500, and the second transmission bevel tooth 510 is meshed with the first transmission bevel tooth 320 for transmission, so as to drive the first transmission member 300 to rotate through the rotation of the second transmission member 500.

[0049] The rotation axes of the first transmission member 300 and the second transmission member 500 are usually arranged vertically, that is, the rotation axes of the first transmission bevel gear 320 and the second transmission bevel gear 510 are usually arranged vertically, so as to reduce the size of the dimming system along the axial direction of the adjustment shaft 130. The extension direction of the first transmission skipping tooth 220 is parallel to the axial direction of the adjustment cylinder 200, and the extension direction of the second transmission skipping tooth 310 is parallel to the axial direction of the first transmission member 300.

[0050] The dimming system disclosed in the present invention can be applied to the horizontal adjustment of vehicle headlights. During normal adjustment, the second transmission member 500 is rotated by adjusting the second transmission member 500, and the second transmission member 500 drives the first transmission member 300 to rotate through the engagement of the second transmission bevel gear 510 with the first transmission bevel gear 320. The first transmission member 300 drives the adjustment cylinder 200 to rotate through the engagement of the second transmission jump tooth 310 with the first transmission jump tooth 220. The rotation of the adjustment cylinder 200 is converted into an axial position movement of the ball head 110 through the cooperation of the second adjusting thread 210 and the first adjusting thread 131 on the adjusting shaft 130. The ball head 110 then cooperates with the ball head seat to adjust the light output angle of the vehicle lamp. When the sliding bracket 100 moves axially to the extreme position, and then the second transmission member 500 is forcibly operated to rotate, under the action of the deformation release groove, among the various components of the dimming system, the adjusting cylinder 200 and / or the first transmission member 300 will undergo elastic deformation first, and cause the second transmission tooth 310 to jump relative to the first transmission tooth 220. At this time, the first transmission member 300 rotates relative to the adjusting cylinder 200, and the transmission chain is cut off and cannot be further transmitted by the adjusting cylinder 200, thereby realizing the limitation of the axial movement of the sliding bracket 100 and realizing the anti-adjustment function.

[0051] Compared with the prior art, the dimming system disclosed in the present invention adds a transmission node between the adjustment cylinder 200 and the first transmission member 300, and sets the transmission node as a weak point on the transmission chain, so that after the axial stroke of the sliding bracket 100 moves to the extreme position, the second transmission jumping tooth 310 can jump the elastic position of the first transmission jumping tooth 220 to complete the anti-adjustment function, thereby reducing the risk of damage to the dimming system and other parts of the car lamp during the adjustment of the car lamp angle, thereby extending the service life of the car lamp.

[0052] Specifically, in order to ensure the reliable implementation of the anti-disengagement function, the first transmission jumping tooth 220 and the second transmission jumping tooth 310 are clearance-matched, and the first transmission jumping tooth 220 and the second transmission jumping tooth 310 are made of plastic or metal materials with a certain elasticity to facilitate the elastic deformation of the adjustment cylinder 200 and the first transmission member 300, thereby realizing the jumping of the second transmission jumping tooth 310 relative to the first transmission jumping tooth 220.

[0053] Combination Figure 5 and Figure 6In a specific embodiment disclosed in the present invention, the deformation release groove includes a first deformation release groove 203 and / or a second deformation release groove 201. The first deformation release groove 203 and / or the second deformation release groove 201 are arranged on the adjustment tube 200, and along the axial direction of the adjustment tube 200, the first deformation release groove 203 is arranged opposite to the first transmission skipping tooth 220, and the second deformation release groove 201 is arranged staggered with the first transmission skipping tooth 220. The setting of the first deformation release groove 203 facilitates the radial contraction deformation of the adjustment tube 200 at the position of the first transmission skipping tooth 220, thereby facilitating the skipping of the second transmission skipping tooth 310; the setting of the second deformation release groove 201 improves the elastic deformation performance of the adjustment tube 200 as a whole, which can further facilitate the deformation of the adjustment tube 200 as a whole, thereby facilitating the skipping of the second transmission skipping tooth 310, and at the same time can also reduce the weight and cost of the adjustment tube 200.

[0054] In other embodiments, in combination Figure 7-Figure 9 The deformation release groove includes a third deformation release groove 301, which is disposed on the first transmission member 300, and along the axial direction of the first transmission member 300, the third deformation release groove 301 is arranged opposite to the second transmission skipping tooth 310, and is arranged offset with the first transmission bevel tooth 320. The third deformation release groove 301 is used to allow the first transmission member 300 to expand and deform in the radial direction, thereby facilitating the second transmission skipping tooth 310 to skip relative to the first transmission skipping tooth 220, while not affecting the structural strength of the first transmission bevel tooth 320.

[0055] The first deformation release groove 203, the second deformation release groove 201 and the third deformation release groove 301 can be provided together, and the number is not limited to one, two or three. When there are multiple, they need to be arranged at equal intervals around the axis of the adjustment cylinder 200 and the first transmission member 300 to ensure uniform deformation of the adjustment cylinder 200 and the first transmission member 300. In addition, the first deformation release groove 203 and the third deformation release groove 301 can be provided as a structure with one end open to improve the elastic deformation capacity of the adjustment cylinder 200 and the first transmission member 300.

The first axial positioning groove 202 and the first positioning protrusion 330 are positioned so that during the adjustment process, the adjustment cylinder 200 and the first transmission member 300 can only rotate relative to each other, but cannot move relative to each other axially. In addition, the first axial positioning groove 202 and the first positioning protrusion 330 can be interchanged without affecting the realization of their functions, that is, the first positioning protrusion 330 can be arranged on the outer wall of the adjustment cylinder 200, and the first axial positioning groove 202 can be arranged on the inner wall of the first transmission member 300.

[0060] To facilitate installation, combine Figure 1-Figure 3The dimming system further includes a lamp housing fixing part 600 for connecting with the lamp housing. The lamp housing fixing part 600 is provided with a slide groove 601, which extends along the axial direction of the adjustment shaft 130.

Figure 4 In order to ensure stable sliding of the sliding bracket 100 , the sliding protrusions 121 can be symmetrically arranged on both sides of the mounting seat 120 .

[0061] Specifically, the lamp housing fixing member 600 can be connected to the adjustment housing 400 by screws.
