[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] Example 1, please refer to Figure 1-Figure 4This embodiment provides a vehicle lighting device based on embodiment 1, including: a base 1; the base 1 is the basic component of the entire lighting device, which plays a role in supporting the entire system. It fixes the lamp on the vehicle to ensure that the lamp is stable and does not deviate or damage during movement; a mounting plate 2, which is arranged at the upper end of the base 1; a lamp body 3, which is assembled at the bottom of the mounting plate 2. The lamp body 3 is the core part of the lighting device and is responsible for providing light source; the upper end of the base 1 is fixedly connected to a mounting seat 41, and the outer wall of the mounting seat 41 is provided with a mounting groove 42, and the interior of the mounting groove 42 is fixedly installed with an electric Turntable 411, the output shaft of the electric turntable 411 is fixedly connected to the ratchet 43, and the two sides of the mounting base 41 are rotatably connected to the magnet A44 and the magnet B47, the inner side of the magnet A44 is hinged with a pawl 45, and the outer walls of the ratchet 43 and the magnet B47 are respectively fixedly connected to the reciprocating screw A46 and the reciprocating screw B48, and the outer walls of the reciprocating screw A46 and the reciprocating screw B48 are both threadedly connected to the moving block 412, and the side of the moving block 412 is hinged with a connecting rod A49, and the upper end of the base 1 is hinged with a connecting rod B410, the top of the connecting rod B410 is hinged to the middle part of the connecting rod A49, and the top of the connecting rod A49 is hinged to the bottom of the mounting plate 2. A spring 413 is fixedly attached to the inner wall of magnet A44. The other end of spring 413 is fixedly connected to pawl 45. Spring 413 and pawl 45 work together to provide a restoring force, ensuring that pawl 45 always firmly engages the gear of ratchet 43, preventing reverse rotation. Magnet A44 and magnet B47 are symmetrically positioned on either side of mounting base 41 and magnetically connected to each other. The exterior of mounting plate 2 is equipped with an adjustment assembly 5 and a dust removal assembly 6.

[0028] When in use, first install the base 1 on the vehicle. When the height of the lamp body 3 needs to be adjusted, start the electric turntable 411 to drive the ratchet 43 (to adjust the height of the lamp body 3). Figure 3As an example, the ratchet 43 rotates counterclockwise, and under the action of the pawl 45, the ratchet 43 can drive the magnet A44 to rotate together. When the magnet A44 rotates, the magnet B47 magnetically connected thereto will rotate at the same time. Then, the reciprocating screw A46 and the reciprocating screw B48 on the outer wall of the ratchet 43 and the magnet B47 will rotate at the same time, and the thread directions of the reciprocating screw A46 and the reciprocating screw B48 are opposite, so that the moving block 412 threadedly connected to the outer wall of the reciprocating screw A46 and the reciprocating screw B48 can move outward at the same time, thereby driving the bottom of the connecting rod A49 to approach the bottom of the connecting rod B410. The other end is hinged to the middle of the connecting rod A49 and is of the same length as the connecting rod B410. When the connecting rod A49 approaches the connecting rod B410, the top of the connecting rod B410 will increase the supporting force for the connecting rod A49, and the tilt state of the connecting rod A49 will tend to be vertical. Then, the top of the connecting rod A49 can lift the mounting plate 2, thereby increasing the height of the lamp body 3. When the moving block A412 moves to the outermost end of the reciprocating screw rod A46 and the reciprocating screw rod B48, the moving block A412 will move inward. At this time, the height of the mounting plate 2 can be lowered. If the pitch angle of the lamp body 3 needs to be adjusted, the electric turntable 411 drives the ratchet 43 (to Figure 3 For example, when the mounting plate 2 is rotated clockwise, only the ratchet 43 rotates, and only the reciprocating screw A46 rotates, and only the moving block A412 on that side moves. Similarly, only the height of the mounting plate 2 on that side will be adjusted, and the mounting plate 2 can be tilted, thereby realizing the adjustment of the pitch angle of the lamp body 3. When the mounting plate 2 needs to be rebalanced, the moving block A412 on the outer wall of the reciprocating screw A46 is moved to a symmetrical position with the moving block A412 on the other side.

[0029] Example 2, please refer to Figures 1-6 Based on Example 1, the adjustment assembly 5 includes a through slot 51 formed in the outer wall of the mounting plate 2. A rotating shaft 52 is rotatably connected to the inner wall of the through slot 51. A linkage rod 53 is fixedly mounted on the outer wall of the rotation shaft 52. A curved baffle 54 is fixedly mounted on the bottom of the linkage rod 53. A ☐-shaped seat 56 is fixedly mounted on the upper end of the mounting plate 2. A through hole is formed in the middle of the ☐-shaped seat 56, and a lifting rod 57 is slidably mounted within the through hole. A support plate 58 is fixedly mounted on the bottom of the lift rod 57. An L-shaped rod 59 is fixedly mounted on the bottom of the support plate 58. The other end of the L-shaped rod 59 slides through the mounting plate 2. A torsion spring 510 is movably mounted on the outer wall of the rotation shaft 52. The ends of the torsion spring 510 are respectively fixedly mounted on the through slot 51 and the linkage rod 53. An elastic baffle 55 is installed between the curved baffles 54.

[0030] During use, when the mounting plate 2 descends, since the bottom of the L-shaped rod 59 contacts the upper surface of the base 1, when the distance between the mounting plate 2 and the base 1 shrinks, the L-shaped rod 59 will slide upward. Then, the pressing plate 58 at the top of the L-shaped rod 59 will rise accordingly, and further squeeze the top of the linkage rod 53, so that the linkage rod 53 can rotate around the rotating shaft 52. Since the top of the linkage rod 53 rotates outward, the arc-shaped baffle 54 at the bottom of the linkage rod 53 will close towards the middle, and the elastic cloth 55 between the arc-shaped baffles 54 will be tightened. When the distance between the mounting plate 2 and the base 1 increases, under the action of the torsion spring 510, the top of the linkage rod 53 will rotate inward, and then the arc-shaped baffle 54 at the bottom of the linkage rod 53 will rotate outward, so that the arc-shaped baffle 54 opens and the elastic cloth 55 between the arc-shaped baffles 54 is stretched. When the mounting plate 2 descends, the height of the lamp body 3 decreases, and at this time the irradiation range will shrink. Then, when the arc-shaped baffles 54 around the lamp body 3 open a little, the irradiation range can be restored. On the contrary, when the lamp body 3 rises, the arc-shaped baffles 54 contract, which can prevent the height from being too high and the light from being scattered.

[0031] Embodiment 3, please refer to Figure 1-Figure 7 , on the basis of Embodiment 1, the dust removal component 6 includes a guiding groove 61, which is opened on the outer wall of the lifting rod 57. The upper end of the U-shaped seat 56 is rotatably connected with a rotating ring 62. The inner wall of the rotating ring 62 is fixedly connected with a sliding shaft 63. The upper end of the mounting plate 2 is provided with an airbag 64. The bottom of the airbag 64 is assembled with an air outlet pipe 65 through a rotary joint. The outer wall of the rotating ring 62 is fixedly connected with a connecting rod 66. The other end of the connecting rod 66 is fixedly connected with the air outlet pipe 65. The bottom of the lifting rod 57 is fixedly connected with a pressing plate 69. An activity groove 68 is opened at the upper end of the mounting plate 2, and an activity cavity 67 is opened inside the mounting plate 2. The connecting rod 66 is slidably connected with the inner wall of the activity groove 68. The air outlet pipe 65 is movably connected inside the activity cavity 67. The sliding shaft 63 is slidably connected with the guiding groove 61. The bottom of the pressing plate 69 is in contact with the upper surface of the airbag 64.

[0032] During use, when the pressing plate 58 moves downward under the extrusion of the linkage rod 53, the lifting rod 57 at the bottom of the pressing plate 58 will descend accordingly, and then the pressing plate 69 at the bottom of the lifting rod 57 will descend accordingly. Thus, the pressing plate 69 will squeeze the airbag 64, and then the bottom end of the air outlet pipe 65 assembled with the airbag 64 through the rotary joint will blow air to the outside, so that the dust on the surface of the lamp body 3 can be blown away. At the same time, when the lifting rod 57 descends, since the sliding shaft 63 on the inner wall of the rotating ring 62 is slidably connected inside the guiding groove 61, the rotating ring 62 will rotate accordingly. Then, the rotating ring 62 can drive the air outlet pipe 65 to rotate through the connecting rod 66, so that the air outlet pipe 65 can blow dust around the lamp body 3 evenly.

[0033] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
