[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-3 An embodiment of this utility model is provided: an LED vehicle light with adjustable light source angle, including a mounting plate 5 for mounting a light source body 6, which rotates under the drive of a fixing plate 15. The light source body 6 is fixedly connected to the outer wall of the mounting plate 5, and a connecting plate 4 is rotatably connected to the outer wall of the mounting plate 5. A rotating component is provided inside the connecting plate 4.

[0026] The rotating assembly includes a gear 20, a rotating disk 22, and a fixed plate 15. The outer wall of the fixed plate 15 is fixedly connected to the lower part of the mounting plate 5 and to the rotating disk 22, driving the mounting plate 5 to rotate and thus adjusting the angle of the light source body 6. The gear 20 is located inside the connecting disk 4 and rotates around the rotating shaft 21 under the drive of the rack 18, converting linear motion into circular motion and transmitting power to the rotating disk 22. The rotating disk 22 is located inside the connecting disk 4 and rotates together with the gear 20, thereby driving the fixed plate 15 to rotate. The inner wall of the rotating disk 22... A rotating shaft 21 is rotatably connected, and a support frame 19 is fixedly connected to the outer wall of the rotating shaft 21. A support plate 17 is fixedly connected to the outer wall of the support frame 19, and a rack 18 is slidably connected to the inner wall of the support plate 17. Under the push of the electric push rod 16, the rack 18 moves linearly and is converted into the circular rotation of the gear 20 through meshing with the gear 20. The rack 18 meshes with the gear 20. An electric push rod 16 is fixedly connected to the outer wall of the connecting plate 4. The output end of the electric push rod 16 is fixedly connected to the outer wall of the rack 18, and a fixing block 7 is slidably connected to the outer wall of the rack 18.

[0027] Specifically, when the electric push rod 16 is powered on, its output end extends and pushes the rack 18 to move linearly along the slide rail preset on the support plate 17. Since the rack 18 and the gear 20 are meshed, during the translation of the rack 18, the gear 20 rotates around the fixed axis under its drive. When the gear 20 rotates, it will drive the rotating disk 22 to rotate synchronously along the outer wall of the rotating shaft 21. The rotating disk 22 is fixedly connected to the fixed plate 15. Therefore, the rotation of the rotating disk 22 will drive the fixed plate 15 to rotate. Since the outer wall of the fixed plate 15 is fixedly connected to the outer wall of the mounting plate 5, the rotation of the fixed plate 15 will drive the mounting plate 5 to rotate. The light source body 6 installed on the mounting plate 5 will also change its angle accordingly, thereby achieving the effect of adjusting the angle of the light source body 6.

[0028] Reference Figure 4 and Figure 5A fixed plate 3 is fixedly connected to the lower surface of the connecting plate 4. A base 2 is fixedly connected to the lower surface of the fixed plate 3. A heat sink 1 is fixedly connected to the lower surface of the base 2. An installation component is provided on the inner wall of the connecting plate 4. The installation component includes a locking block 10, which is engaged in a slot inside the connecting plate 4 to fix the connecting plate 4 and the light source body 6. Under the action of the sliding plate 11, it disengages from the slot, releasing the fixation of the light source body 6, thus achieving quick disassembly and installation. The outer wall of the locking block 10 is slidably connected to the inner wall of the connecting plate 4. A connecting rod 9 is fixedly connected to the outer wall of the locking block 10, connecting the sliding plate 11 and the locking block 10, transmitting the movement of the sliding plate 11, so that the locking block 10 can accurately engage or disengage from the slot inside the connecting plate 4. One end of the connecting rod 9 is fixedly connected to the sliding plate 11, which moves along its outer wall under the drive of the bidirectional screw 12, driving the locking block 10 to move through the connecting rod 9. The inner wall of the sliding plate 11 is threaded. A bidirectional lead screw 12 rotates, driving two sliding plates 11 to move relative to or away from each other, thereby controlling the position of the locking block 10 and completing the fixing and disassembly of the light source body 6. A handle 13 is fixedly connected to one end of the bidirectional lead screw 12. A guide rod 8 is slidably connected to the inner wall of the sliding plate 11. A groove 14 is opened inside the fixed plate 3. The outer wall of the support plate 17 is fixedly connected to the inner wall of the fixed plate 15. The support plate 17 is used to support the rotating disk 22. The rotating disk 22 is fixedly connected to the outer wall of the fixed plate 15. The fixed plate 15 is used to drive the mounting plate 5 to rotate. Both ends of the guide rod 8 are fixedly connected to the inner wall of the fixed plate 3. The guide rod 8 is used to guide the movement of the sliding plate 11. The outer wall of the sliding plate 11 is slidably connected to the inner wall of the fixed plate 3. The sliding plate 11 is used to drive the connecting rod 9 to move. The handle 13 is located outside the fixed plate 3. The handle 13 is used to drive the bidirectional lead screw 12 to rotate.

[0029] Specifically, by rotating the handle 13, the bidirectional lead screw 12 is driven to rotate. The bidirectional lead screw 12 has two sections with opposite threads. Its rotation will drive the two sliding plates 11 to move relative to each other or in opposite directions along the outer wall of the bidirectional lead screw 12. When it is necessary to disassemble the light source body 6, the rotation of the bidirectional lead screw 12 causes the two sliding plates 11 to move in opposite directions. Through the connecting rod 9, the locking block 10 is driven to gradually move away from the locking groove inside the connecting plate 4, releasing the fixing of the connecting plate 4. Thus, the connecting plate 4 and its internal components, as well as the light source body 6 above, can be disassembled. At this time, the light source body 6 can be quickly disassembled. When installing the light source body 6, simply rotate the handle 13 in the opposite direction to drive the sliding plates 11 to move relative to each other, so that the locking block 10 is re-locked into the locking groove inside the connecting plate 4, thereby achieving a stable fixation of the light source body 6.

[0030] Working principle: When an adjustable LED headlight is needed, the output end of the electric push rod 16 can be controlled to push the rack 18 to move along the outer wall of the support plate 17. As the rack 18 moves, since the rack 18 and the gear 20 are meshed, the gear 20 rotates with the movement of the rack 18. As the gear 20 rotates, it will drive the rotating disk 22 to rotate along the outer wall of the rotating shaft 21, which in turn drives the fixing plate 15 to rotate. Since the outer wall of the fixing plate 15 is fixedly connected to the outer wall of the mounting plate 5, the rotation of the fixing plate 15 will drive the mounting plate 5 to rotate, thereby achieving the effect of adjusting the angle of the light source body 6.

[0031] Furthermore, when it is necessary to replace the mounting plate 5 and the light source body 6, firstly, by turning the handle 13, the bidirectional lead screw 12 is rotated. The rotation of the bidirectional lead screw 12 will cause the two sliding plates 11 to move relative to each other or in opposite directions along the outer wall of the bidirectional lead screw 12. When it is necessary to disassemble the light source body 6, the bidirectional lead screw 12 will cause the sliding plates 11, the connecting rod 9, and the locking block 10 to move away from the inside of the connecting plate 4, thereby releasing the fixing of the connecting plate 4 and the light source body 6, and the light source body 6 can be quickly disassembled. When installing the light source body 6, simply turn the handle 13 in the opposite direction to drive the sliding plates 11 to move relative to each other, so that the locking block 10 is locked into the inside of the connecting plate 4, thereby fixing the light source body 6.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
