Gear 13 is fixedly connected to the outer side of the transmission shaft 12. Gear 11 and gear 13 mesh. In use, the rack 8 at the front end is moved by starting the cylinder 9. When the rack 8 moves, it can drive the sliders 6 at both ends to move synchronously. The slider 6 slides along the upper end of the slide rod 5 inside the groove 7. When the rack 8 reaches the front end, it contacts gear 11. Under the action of the rack 8, gear 11 is fixed, thereby completing the fixation of the angle adjustment component.

[0020] Reference Figure 3 This utility model discloses an angle-adjustable automotive lighting device, comprising a round rod 20 rotatably connected to the lower rear end of the inner side of a fixed frame 1, a lampshade 2 fixedly connected to the upper end of the round rod 20, the upper end of the lampshade 2 being fixedly connected to a drive shaft 10, a lamp assembly 19 fixedly connected to the rear end of the inner side of the lampshade 2, a lens 15 fixedly connected to the front end of the lampshade 2, a steering groove 17 formed at the upper and lower ends of the inner side of the fixed frame 1, a limit block 18 slidably connected to the inner side of the steering groove 17, a connecting rod 16 fixedly connected to the upper end of the limit block 18, the connecting rod 16 being fixedly connected to the lampshade 2, and fixed blocks 22 fixedly connected to the left and right sides of the front end of the fixed frame 1, with grooves formed inside the fixed blocks 22, and a rotating rod 21 rotatably connected inside the grooves. During use, gears... The second gear 13 adopts a fan-shaped structure. During use, it rotates by the second transmission shaft 12. When rotating, it drives the second gear 13 to rotate synchronously. The second gear 13 adopts a fan-shaped structure. When the second gear 13 rotates, it drives the first gear 11 to rotate, which in turn drives the inner transmission shaft 10 to rotate. Under the rotation of the first transmission shaft 10, the lamp cover 2 rotates. When the lamp cover 2 rotates, the lower end of the round rod 20 rotates synchronously, which drives the lower end of the connecting rod 16 to move synchronously. Under the action of the connecting rod 16, the limiting block 18 rotates along the inner side of the turning groove 17. During use, the limiting of the limiting block 18 by the turning groove 17 and the cooperation of the round rod 20 make the lamp cover 2 more stable when moving.

[0021] Reference Figure 4 This utility model discloses an angle-adjustable automotive lighting device, comprising: a rotating rod 21 with a pull rod 14 fixedly connected to its upper end; a fixed frame 1 with rotating rods 4 rotatably connected to its left and right ends at the rear end; a lamp cover 2 with a connecting wire 23 fixedly connected to its rear end, the connecting wire 23 passing through the fixed frame 1; and a connecting port 24 fixedly connected to the rear end of the connecting wire 23. In use, the connecting port 24 can connect to an outer connecting end, and power is supplied to the lamp assembly 19 by contact between the connecting port 24 and the connecting end. When the height of the lamp cover 2 needs to be adjusted, the pull rod 14 is pulled to move, thereby moving the fixed frame 1. The movement of the fixed frame 1 causes the rotating rods 4 at both ends to rotate, thus completing the height adjustment.

[0022] Working principle: When the angle of the lighting device needs to be adjusted, the cylinder 9 is activated, causing the piston rod inside the cylinder 9 to move inward. This drives the rack 8 to move the slider 6, disengaging the rack 8 from the gear 11. At this time, the transmission shaft 12 rotates, driving the lower gear 13 to rotate. Under the meshing action, the gear 11 rotates synchronously, driving the inner transmission shaft 10 to rotate. When the transmission shaft 10 rotates, it drives the lampshade 2 to rotate. As the lampshade 2 rotates, its lower rear end moves along the round rod 20. The cylinder rotates synchronously, driving the connecting rod 16 at the front end to rotate synchronously. Under the action of the connecting rod 16, the limiting block 18 at the lower end rotates synchronously. When the limiting block 18 moves, it moves along the inner side of the turning groove 17, thereby completing the adjustment of the angle of the lamp cover 2. After the left and right angles are adjusted, the cylinder 9 is activated. Under the action of the cylinder 9, the rack 8 at the front end is pushed to move. When the rack 8 moves, it drives the sliders 6 at both ends to slide along the inner side of the sliding groove 7 on the upper end of the sliding rod 5. When the rack 8 moves to the front end, it meshes with the gear 11, thereby completing the fixation of the gear 11 and realizing the limiting of the angle adjustment component.
