[0002] With the widespread application of LED technology in the field of car lights, the cool lighting mode of car lights when welcoming guests, charging, and locking the car is becoming more and more popular. At the same time, with the development of the industry and the entry of new energy fields, higher requirements are put forward for the lighting mode of car lights when welcoming guests, charging, and locking the car. The previous static lighting mode can no longer meet customer requirements and is relatively monotonous. Utility Model Content

[0003] In order to solve the above problems existing in the prior art, the utility model provides a self-rotating light-emitting structure of a car light, which realizes dynamic rotation of the car light to emit bright light through a gear assembly, satisfying customers' pursuit of cool light-emitting modes of car lights.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-rotating light-emitting structure of a vehicle lamp, comprising a bracket, a gear assembly, a light source and a plurality of optical components, wherein the gear assembly is arranged on the bracket, the light source is arranged in the middle of the gear assembly, and the optical components are arranged around the gear assembly, and the gear assembly drives the optical components to revolve around the light source while realizing self-rotation.

[0005] Furthermore, the gear assembly includes several gears 1, 2, 3, 4 and several bases, gear 3 is movably arranged on the bracket, gear 2 is fixedly arranged in the middle of the bracket, several bases are evenly arranged on the circumference of gear 3, gear 1 is movably arranged at the bottom of the base, gear 1 is meshed with gear 2, gear 4 is movably arranged on the bracket and meshed with gear 3.

[0006] Furthermore, the bracket, gear two and gear three are hollowed out in the middle, and the light source is fixed in the middle of gear three and protrudes out of the hollowed out part.

[0007] Furthermore, the optical component is fixed on the base.

[0008] Compared with the prior art, the beneficial effects of the utility model are: the utility model has a simple structure, and the motor drives gear four to rotate, thereby driving gear three to rotate. The rotation of gear three drives gear one to revolve around the light source. Since gear three is meshed with gear two and gear two is fixed, gear three rotates itself, thereby achieving the optical component rotating around the light source while also rotating itself, forming a brilliant dynamic effect; since the light source and gear three are fixed, gear three drives the light source and the optical component to rotate together, reducing the difficulty of circuit connection.

[0010] Figure 2 This is a schematic diagram of the structure of the utility model Figure 2 . DETAILED DESCRIPTION

[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0012] See also Figure 1-2 The technical solution provided by the utility model is: a self-rotating luminous structure of a car lamp, including a bracket 1, a gear assembly, a light source 8 and a plurality of optical components 7. The gear assembly is arranged on the bracket 1. After the gear assembly and the bracket 1 are matched, the middle is hollowed out. The light source 8 is arranged in the hollow part in the middle of the gear assembly. The light source 8 is connected to the high and low beam lenses behind the light source 8. The optical components 7 are arranged around the gear assembly. The gear assembly drives the optical component 7 to revolve around the light source 8 while the optical component 7 itself rotates. The self-rotating luminous structure of the car lamp can be used as a welcome mode when the car is started, or a display mode during the charging process of the car, or a farewell mode when the driver locks the car and leaves.

[0013] Specifically, the gear assembly includes a plurality of gears 1 2, gears 2 3, gears 3 4, gears 4 5 and a plurality of bases 6. The bracket 1, gears 2 3 and gears 3 4 are hollowed out in an annular shape. Gears 3 4 are movably arranged on the bracket 1. Gears 2 3 are fixedly arranged in the hollow part in the middle of the bracket 1. After the bracket 1, gears 2 3 and gears 3 4 are matched, the middle is hollowed out. A light source 8 is fixed in the middle of gears 3 4 and protrudes from the hollow part. The light source 8 can rotate synchronously with gears 3 4. A plurality of bases 6 are evenly arranged on the annular circumference of gears 3 4. Gear 1 2 is movably arranged at the bottom of the base 6. An optical component 7 is fixed on the base 6. Gear 1 2 is meshed with gears 2 3. Gears 4 5 are movably arranged on the bracket 1 and meshed with gears 3 4. Connect a DC motor or a stepper motor. When the self-rotating light-emitting structure of the car lamp works, first the DC motor or the stepper motor starts to drive gear four 5 to rotate. Gear four 5 meshes with gear three 4. Gear four 5 drives gear three 4 to rotate. Gear three 4 is fixedly connected to the light source 8, so gear three 4 drives the light source 8 to rotate together. Gear one 2 will also rotate around the light source 8 with gear three 4 on the annular circumference of gear three 4. Gear one 2 meshes with gear two 3. Gear two 3 is fixed in the middle of the bracket 1. Therefore, the position setting of gear one 2 and gear two 3 makes gear one 2 itself rotate. Gear one 2 drives the optical component 7 on it to rotate, so that the optical component 7 and the light source 8 can be synchronously rotated, reducing the difficulty of circuit connection.

[0014] Specifically, the optical component 7 is a diamond optical component, and the luminous effect is more brilliant.

[0015] Specifically, the diameter of the ring of gear three 4 is smaller than that of bracket 1.

[0016] The installation process of the utility model is as follows: first, install the gear 1 2 under the base 6 of the gear 3 4 through the bearing, then install the gear 4 5 and the gear 3 4 to the corresponding positions on the bracket 1, so that the gear 4 5 and the gear 3 4 are meshed, and then connect the DC motor or the stepper motor to the gear 4 5, and then fix the gear 2 3 to the hollow part in the middle of the bracket 1, so that the gear 2 3 is meshed with the gear 1 2, and finally install the light source 8 in the middle of the gear 3 4, and install the optical component 7 on the base 6, and the assembly is completed.

[0017] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
