[0001] The present invention relates to the technical field of lighting devices, and in particular to a vehicle lamp dimming drive mechanism and a vehicle lamp having the same. Background Art

[0002] The headlights provide high and low beam lighting for the car. Due to assembly reasons, the headlights need to be adjusted after installation, that is, the illumination angle of the headlights needs to be changed so that the illumination of the light meets the national standards. The principle of the commonly used dimming structure is to change the relative angle of the lamp group or the lamp frame with the lamp group by driving the rotation of one or more adjustment screws to achieve the change of the illumination angle of the lamp group.

[0003] In the prior art, such as a dimming device for an automobile lamp and an automobile lamp with application number 202322120250.6, it is disclosed that a first threaded rod is driven to rotate by rotating a rotating shaft to drive a connecting block to slide inside a lamp housing, and a connecting ball of the connecting block cooperates with a spherical groove of the adjustment block to drive the lamp on the adjustment block to adjust the distance. However, in terms of specific structure, the assembly and coordination between the screws and the installation of the various components are relatively complicated, which makes the overall driving mechanism relatively complicated, which not only occupies a large space, but also is not easy to assemble quickly. Summary of the invention

[0004] The object of the present invention is to provide a vehicle light dimming drive mechanism and a vehicle light having the same, wherein a pair of L-shaped plates are fixed in the card slots by means of a pair of card slots that squeeze a pair of L-shaped plates on the fasteners, and a rotating shaft in the rotating slot is limited by an arc-shaped plate. Through the use of fasteners, the assembly structure is simpler and more effective, and the rotating shaft and the fasteners are easier to install, thereby improving the assembly efficiency.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a vehicle light dimming driving mechanism, comprising:

[0006] A base plate is provided with an open rotating groove, and a pair of slots are symmetrically provided above and below the rotating groove. A positioning seat is provided on one side of the base plate, and a mounting seat is provided on the positioning seat. The mounting seat is provided with a first mounting hole and a second mounting hole arranged perpendicular to the first mounting hole.

[0007] The rotating part comprises a rotating shaft and a rotating sleeve, wherein the rotating shaft is rotatably arranged in the rotating groove, one end of the rotating shaft is connected to a driving block, and the other end is connected to the rotating sleeve, and the rotating sleeve is rotatably arranged in the first mounting hole.

When the convex portions are embedded in the embedding grooves, an expansion zone and a rotation zone are formed on the portion of the rotating sleeve where the insertion rod is extended, and the outer diameter of the expansion zone is greater than the outer diameter of the rotation zone. The rotation zone is rotatably located in the first mounting hole. By forming the expansion zone, the rotating sleeve can be limited in the first mounting hole to prevent it from lateral movement.

The arc-shaped plate limits the rotating shaft in the rotating groove. Through the use of the fastener, the assembly structure is simpler and more effective, and the rotating shaft and the fastener are easier to install, which can improve the assembly efficiency.

[0021] 2.

[0034] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0035] like Figures 1 to 5 , combined Figure 7 As shown, a headlight dimming drive mechanism includes a substrate 10, a driving rod 20, a rotating part 30 and a fastener 40. The substrate 10 is provided with an open rotating groove 101, and a pair of clamping grooves 1021 are symmetrically provided above and below the rotating groove 101. A positioning seat 11 is provided on one side of the substrate 10, and a mounting seat 12 is provided on the positioning seat 11. The mounting seat 12 is provided with a first mounting hole 121 and a second mounting hole 122 arranged perpendicular to the first mounting hole 121. The rotating part 30 includes a rotating shaft 31 and a rotating sleeve 32. The rotating shaft 31 is rotatably arranged in the rotating groove 101, and one end is connected to a driving block 3 for connecting to the headlight frame 50. 121, and the other end is connected to the rotating sleeve 32. The rotating sleeve 32 is rotatably arranged in the first mounting hole 121. The driving rod 20 is rotatably arranged in the second mounting hole 122, and is meshed with one end of the rotating sleeve 32 away from the rotating shaft 31, that is, the first gear ring 201 on the driving rod 20 is meshed with the second gear ring 321 on the rotating sleeve 32 to realize rotation transmission. The fastener 40 includes an arc plate 41, and a pair of L-shaped plates 42 symmetrically arranged at both ends of the arc plate 41. The arc plate 41 is provided with a profiling groove 410. The ends of the pair of L-shaped plates 42 are respectively clamped in a pair of clamping grooves 1021 and make the profiling grooves 410 abut against the rotating shaft 31.

[0036] In the present invention, the rotating shaft 31 and the rotating sleeve 32 are connected to form a rotating part 30. The rotating sleeve 32 is driven to rotate by rotating the driving rod 20, and the rotating shaft 31 is driven to rotate by the rotating sleeve 32. Since the lamp frame 50 is rotatably arranged in the lamp housing structure (combined with Figure 7 As shown in the figure, the middle position of the lower end of the lamp frame 50 is hinged on the lamp housing structure, and the driving block 3121 is rotatably connected to one side of the lamp frame 50). When the rotating shaft 31 rotates, it drives the driving block 3121 to swing so that the other end of the driving block 3121 moves upward or downward, so that the lamp frame 50 is driven by the driving block 3121 to swing on the lamp housing structure to complete the dimming action. The fastener 40 is a plastic or metal part that can be deformed under pressure and can recover after the external force disappears. In particular, a pair of L-shaped plates 42 on the fastener 40 form a larger gap on the side of the arc-shaped plate 41, which is conducive to deformation. After the rotating shaft 31 is positioned in the rotating groove 101, the pair of L-shaped plates 42 extend into the card slot 1021. The pair of card slots 1021 can act on the pair of L-shaped plates 42 so that the pair of L-shaped plates 42 can be deformed and supported in the card slot 1021 after being compressed, which facilitates the installation of the fastener 40 on the substrate 10, and the matching of the contoured groove 410 of the arc-shaped plate 41 and the rotating groove 101 can ensure the normal rotation of the rotating shaft 31. Through the use of the fastener 40, the assembly structure is simpler and more effective, and the rotating shaft 31 and the fastener 40 are easier to install, which can improve the assembly efficiency.

[0037] Specifically, the rotating shaft 31 includes a rotating rod 311, and a ball head 312 and an insert rod 313 respectively arranged at both ends of the rotating rod 311. The rotating rod 311 is an optical axis structure, which can be rotatably arranged between the rotating groove 101 and the contoured groove 410, and can effectively reduce the resistance generated during rotation to ensure smooth rotation. The ball head 312 is connected to the driving block 3121, and the insert rod 313 is arranged in the rotating sleeve 32.

[0038] Combined with Figure 6 As shown, a concave cavity 3201 is provided on the rotating sleeve 32, and a plurality of embedding grooves 3202 are provided on the side wall of the concave cavity 3201. A plurality of convex portions 3131 matching the embedding grooves 3202 are provided on the side wall of the insertion rod 313. After the insertion rod 313 is extended into the concave cavity 3201, the convex portions 3131 are embedded in the embedding grooves 3202. Through the cooperation between the convex portions 3131 and the embedding grooves 3202, the rotating shaft 31 can be rotated synchronously with the rotating sleeve 32.

[0039] Furthermore, a plurality of gaps 3203 communicating with the concave cavity 3201 are provided on the side wall of the rotating sleeve 32, and a plurality of grooves 3202 are continuously provided on the side wall of the concave cavity 3202 between a pair of adjacent gaps 3203, and a plurality of protrusions 3131 are continuously provided on the side wall of the insertion rod 313. When the protrusions 3131 are embedded in the grooves 3202, the protrusions 3131 squeeze the side wall of the rotating sleeve 32 so that the portion of the rotating sleeve 32 where the insertion rod 313 extends forms an expansion zone 322 and a rotation zone 323, the outer diameter of the expansion zone 322 is greater than the outer diameter of the rotation zone 323, and the rotation zone 323 is rotatably located in the first mounting hole 121. On the basis of the cooperation between the protrusion 3131 and the embedding groove 3202 to realize the synchronous rotation of the rotating shaft 31 and the rotating sleeve 32, the setting of the gap 3203 can make the rotating sleeve 32 have the gap 3202 after the insertion of the insertion rod 313. The position is squeezed outward to form an expansion area 322. The formation of the expansion area 322 and the common limitation of the second tooth ring 321 on the other side of the rotating sleeve 32 can position the rotating sleeve 32 along its axial direction in the first mounting hole 121, that is, the rotating area 323 can be rotatably located in the first mounting hole 121, and no horizontal displacement will occur, thereby ensuring the stability of installation and position. Based on the above arrangement, when the rotating shaft 31 and the rotating sleeve 32 of the present invention are installed on the substrate 10, the mounting seat 12 is arranged on the positioning seat 11, the positioning seat 11 is provided with a positioning hole 111, and is provided with a plurality of bayonet holes 110 connected to the positioning hole 111, and the mounting seat 12 is provided with a plurality of plug blocks 120 matching the bayonet holes 110, when the mounting seat 12 is arranged in the positioning hole 111, the plug blocks 120 are embedded in the bayonet holes 110 to prevent the two from rotating relative to each other, the side with the concave cavity 3201 on the rotating sleeve 32 is extended into the first mounting hole 121, and then the part with the rotating rod 311 on the rotating shaft 31 is embedded in the rotating groove 101, and the plug rod 313 is extended into the concave cavity 3201, and the convex portion 3131 cooperates with the embedded groove 3202 so that the plug rod 313 and The rotating sleeve 32 is accurately positioned, and in the process of continuing to insert the insertion rod 313, the side wall of the rotating sleeve 32 is squeezed outward by the protrusion 313 (due to the gap 3203) to form an expansion area 322. The formation of the expansion area 322 positions the rotating sleeve 32 in the first mounting hole 121, ensuring the precise positioning of the rotating sleeve 32 and the rotating shaft 31. The rotating shaft 31 is then positioned and fixed on the base plate 10 through the fastener 40. The above-mentioned assembly method can realize the sequential and precise installation of the rotating sleeve 32, the rotating shaft 31 and the fastener 40; after completing the above-mentioned installation, the sealing plate 13 is locked on the positioning seat 11. Of course, the driving rod 20 is rotatably set on the second mounting hole 122 and its side is covered by the sealing plate 13, and its end is at least exposed outside the sealing plate 13.

[0040] Furthermore, in order to realize the formation of the expansion zone 322, the diameter of the expansion zone 322 in the cavity 3201 is smaller than the diameter of the rotation zone 322, that is, the projection 3131 extends into the embedded groove 3202 corresponding to the rotation zone 322 and does not cause the expansion of the rotating sleeve 32 at this position, and the gap 3202 does not extend here, and is not deformed due to the limitation of the overall structure of the rotating sleeve 32 at this position. However, due to the existence of the gap and the influence of the inner diameter of the cavity 3201 (embedded groove 3202), the rotating sleeve 32 is easily supported to form the expansion zone 322 at other positions. In another embodiment of the present invention, the inner diameter of the embedded groove 3202 at each position in the cavity 3201 can also be set to remain unchanged, and the projection 3131 on the side of the insertion rod 313 close to the rotating rod 311 is set to have a larger outer diameter, which can also achieve the external support effect on the position of the rotating sleeve 32 with the gap 3203.

[0041] Furthermore, a limiting ring 314 is provided between the rotating rod 311 and the inserting rod 313 to limit the depth of the inserting rod 313 extending into the concave cavity 3201 .

[0042] For example Figure 3 and 4 As shown, a card block 1022 is provided in the card slot 1201, and a socket 421 is provided at the end of the L-shaped plate 42. The socket 421 is sleeved on the card block 1022 to prevent the fastener 40 from being laterally separated from the substrate 10; a card plate 43 is provided at the end of the L-shaped plate 42, and the card plate 43 abuts against the card slot 1031. The setting of the card plate 43 facilitates the card slot 1021 to apply pressure to the L-shaped plate 42 to deform it, and the card plate 43 has a certain height, and it itself can also produce a certain degree of deformation. It is squeezed in the card slot 1021 to improve the connection stability.
