[0026] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0027] As Figures 1 to 3 shown in combination with Figure 5 , an optical element rotation adjustment structure in a headlight includes an inner shell 10, a rotating structure 20 and an outer shell 30. A lighting module 40 and an optical element 50 are provided on the inner shell 10. A slot 102 is provided on one side of the inner shell 10, and a pair of rotating columns 101 are symmetrically provided on opposite sides of the inner shell 10. A pair of rotating grooves 301 are symmetrically provided on the inner side wall of the outer shell 30, and a protrusion 302 corresponding to the rotating groove 301 is formed on the outer side wall of the outer shell 10. The pair of rotating columns 101 are respectively inserted into the pair of rotating grooves 301 to rotatably arrange the inner shell 10 in the outer shell 30. The rotating mechanism 20 includes a first rotating rod 21, a second rotating rod 22 and a swinging member 23. The first rotating rod 21 and the second rotating rod 22 are respectively rotatably arranged on the outer shell 30, and the ends of the two close to each other are engaged. The swinging member 23 includes a nut block 231 and an extension block 232 provided at one end of the nut block 231. The nut block 231 is screwed on the second rotating rod 22, and the extension block 232 at least partially extends into the slot 102.

[0028] In the present utility model, a first rotation hole 3031 and a second rotation hole 3032 are provided on the outer shell 30. The first rotation rod 21 and the second rotation rod 22 are respectively rotatably arranged in the first rotation hole 3031 and the second rotation hole 3032. The first gear disk 211 on the first rotation rod 21 meshes with the second gear disk 221 on the second rotation rod 22. By adjusting the rotation of the first rotation rod 21, the rotation of the second rotation rod 22 can be driven. In the swinging member 23, an extension block 232 at one end extends into the slot 102, and a nut block 231 at the other end meshes with the external thread 222 in the middle of the second rotation rod 22 through its internal thread 2311. When the second rotation rod 22 rotates, the external thread 222 acts on the internal thread 2311 of the nut block 231. Since the extension block 232 is limited, the extension block 231 connected to the extension block 232 moves up and down, driving the extension block 232 to move up and down. And since the extension block 232 cannot rotate, the angle between the extension block 232 and the slot 102 changes, driving the inner shell 10 to rotate relative to the outer shell 30 through its rotating column 101, realizing the rotation of the optical element inside the vehicle lamp.

[0029] In the rotation structure of the present utility model, the connection between the second rotation rod 22 and the inner shell 10 is realized through the swinging member 23 (the integrally formed nut block 231 and extension block 232). The structure of the swinging member 23 itself is simpler and easier to prepare and form. Moreover, the connection relationships between the nut block 231 and the second rotation rod 22, and between the extension block 232 and the slot 102 (insertion) enable the swinging member 23 to be assembled quickly, improving the assembly efficiency and assembly stability.

[0030] Continue as Figure 3 shown, to ensure the limiting stability between the swinging member 23 and the inner shell 10, a convex portion 2321 is provided at one end of the extension block 232 away from the nut block 231. Through the convex portion 2321, the extension block 232 (the swinging member 23) can be prevented from disengaging from the slot 102 and thus from detaching from the inner shell 10.

[0031] Further, a concave surface 2322 with an arc-shaped structure is provided in the middle of at least one of the upper and lower end surfaces of the extension block 232. Preferably, the concave surface 2322 is formed on the lower end surface of the extension block 232. The convex portion 2321 is connected to the concave surface 2322 in a linear structure. The concave surface 2322 has the following two functions: First, the concave surface 2322 enables the extension block 232 to change its position relative to the slot 102 more easily, such as translation and rotation. The concave surface 2322 provides a clearance, avoiding jamming when the extension block 232 rotates relative to the housing 10. On the other hand, the concave surface 2322 enables the extension block 232 to extend into the slot 102 more smoothly. First, the convex portion 2321 is inserted into the slot 102 through an inclined angle, and then the extension block 232 is inserted into the slot 102 by the clearance of the concave surface 2322 and in cooperation with the rotation and translation of the swing member 23.

[0032] To ensure that the end of the extension block 232 can rotate relative to the slot 102 during the up and down movement of the swing member 23, a relief groove 103 allowing the end of the extension block 232 to extend into it is provided on the inner housing 10 beside the slot 102 (especially on the extension side of the slot 102 and the upper and lower sides of the extension side). The existence of the relief groove 103 can avoid jamming during relative rotation.

[0033] The vertical cross-sections of the rotating column 101 and the rotating groove 301 are both frustum of a cone structures, which is convenient for nesting after the two are matched, and can also achieve precise positioning to ensure concentricity.

[0034] The lighting module 40 can be conventionally arranged, such as including a control board 41 provided on the inner housing 10 and a light source 42 provided on the control board 41. The control board 41 is connected to an external power source.

[0035] As Figure 4 As shown, the optical element 50 can be conventionally arranged, and it at least includes an inner lens 51. The inner lens 51 is provided on the inner housing 10 for changing the light. The optical element 50 further includes a reflector 52 and an outer cover 53. The reflector 52 is provided on the inner housing 10 and is located inside the inner lens 51. The reflector 52 at least covers the upper and lower sides of the light source 42 and can be used to reflect the light emitted by the light source 42 to the inner lens 51. The outer cover 53 is provided on the inner housing 10 and encloses the inner lens 51.

[0036] As Figure 5 As shown, the present invention also provides a vehicle lamp, including an outer lens 60 and the above-mentioned optical element rotation adjustment structure inside the vehicle lamp. The outer lens 60 is fixedly provided on the outer housing 30 and encloses the optical element 50.

[0037] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but they will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
