Existing projection lights are equipped with fine-tuning mechanisms to adjust the projection position. However, these mechanisms are typically complex in design, resulting in numerous parts, cumbersome assembly, and a large overall size and cost. This makes them unsuitable for installation in the confined spaces of mid-to-high-end cars, limiting their widespread application. Utility Model Content

It has a simple structure, reduces the number of parts, simplifies the assembly process, occupies little space and has a lower cost.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] An automatic adjustment device for vehicle-mounted projection lights includes a base, a module bracket rotatably disposed inside the base, and a projection module mounted on the module bracket.

[0006] A motor is provided on one side of the base, and a drive gear located inside the base is installed at the output end of the motor. A crescent-shaped gear is provided on the side of the module bracket near the motor, and the crescent-shaped gear meshes with the drive gear.

[0007] When the motor drives the crescent-shaped gear to rotate via the drive gear, the crescent-shaped gear can drive the module bracket to rotate synchronously and drive the projection module to rotate and adjust.

[0008] Furthermore, a first bushing and a second bushing are respectively formed on both sides of the module bracket, and a rotating shaft seat and a resistance device are respectively installed on both sides of the base. The resistance device has a damping shaft that cooperates with the second bushing, and the rotating shaft of the rotating shaft seat cooperates with the first bushing.

[0009] Furthermore, the crescent-shaped gear has a bushing hole, and the second bushing is fitted into the bushing hole. The bushing hole, the second bushing, and the damping shaft are coaxially assembled via key pins. The module bracket and the crescent-shaped gear hold the damping shaft and rotate synchronously.

[0010] Furthermore, a positioning platform is provided on the side wall of the module bracket, and a positioning groove is provided on the side of the crescent-shaped gear, the positioning groove being positioned and engaged with the positioning platform.

[0011] Furthermore, an angle sensor is provided on one side of the base, and a magnetic induction block that senses the angle sensor is provided on the side of the module bracket near the angle sensor.

[0012] Furthermore, an arc-shaped hole for avoiding the magnetic induction block is also provided at the position where the angle sensor is installed on the base.

[0013] Furthermore, a motor hole for mounting a motor is provided on one side of the base.

[0014] Furthermore, the module bracket has heat dissipation holes on its rear side.

[0015] Furthermore, the base has a pivot hole and a damping hole on each side.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. This utility model combines a base, module bracket, crescent-shaped gear, motor, and other components. Relying on the meshing of the drive gear and the crescent-shaped gear, the crescent-shaped gear is mounted on the side of the module bracket. The motor drives the drive gear to rotate the crescent-shaped gear and the module bracket synchronously, thereby achieving rotation adjustment of the projection module. This assembly significantly reduces the lateral space occupied, shrinks the overall lamp size, reduces the number of parts, simplifies the assembly process, saves costs, and makes it easier to install in the confined spaces of high-end cars, thus having a wide range of applications.

[0018] 2. The module bracket of this utility model is designed with a first bushing and a second bushing on both sides. The base is equipped with a rotating shaft seat and a resistance device on both sides. The first bushing cooperates with the rotating shaft of the rotating shaft seat, and the second bushing cooperates with the damping shaft of the resistance device. The second bushing is also fitted with the bushing hole on the crescent tooth gear. In this way, the module bracket can be rotated and installed. The overall structure is simpler, the assembly is more convenient, and it can further save assembly space and reduce the size of the whole lamp.

[0019] 3. This invention improves the stability and accuracy of rotation when the projection module is adjusted by the meshing of the drive gear and the crescent-shaped gear. The resistance design stabilizes the projection module during rotation, ensuring stability during adjustment and preventing projection position shift due to vibration or impact, thus improving the stability and reliability of the projection lamp.

[0029] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0030] like Figure 1-8As shown in this embodiment, an automatic adjustment device for vehicle-mounted projection lights is provided. It mainly consists of a base 1, a module bracket 2, a projection module 3, a motor 4, a crescent-shaped gear 5, a resistance device 6, and a rotating shaft seat 7. The module bracket 2 is rotatably mounted inside the base 1, and the projection module 3 is installed inside the module bracket 2. A heat dissipation hole 200 is provided on the rear side of the module bracket 2 for heat dissipation. A motor hole 101 is provided on one side of the base 1, and the motor 4 is mounted on one side of the base 1 and positioned through the motor hole 101. A small drive gear 40 is installed at the output end of the motor 4, located inside the base 1. The crescent-shaped gear 5 is installed on the side of the module bracket 2 closest to the motor 4, and the crescent-shaped gear 5 meshes with the drive gear 40. When the motor 4 drives the crescent-shaped gear 5 to rotate via the drive gear 40, the crescent-shaped gear 5 drives the module bracket 2 to rotate synchronously, thereby causing the projection module 3 to rotate and adjust. This combination and assembly can greatly reduce the lateral space occupied, reduce the size of the entire lamp, reduce the number of parts, simplify the assembly process, save costs, and make it easier to install in the small space of high-end cars, with a wide range of applications.

[0031] Specifically, in this embodiment, a first bushing 21 and a second bushing 22 are respectively formed on both sides of the module bracket 2. A pivot hole 103 and a damping hole 102 are respectively opened on both sides of the base 1. A pivot seat 7 and a resistance device 6 are respectively installed on both sides of the base 1. The pivot of the pivot seat 7 passes through the pivot hole 103. The resistance device 6 has a damping shaft 60 passing through the damping hole 102. The damping shaft 60 of the resistance device 6 cooperates with the second bushing 22, that is, the second bushing 22 is fitted on the damping shaft 60. The pivot of the pivot seat 7 cooperates with the first bushing 21, that is, the first bushing 21 is fitted on the pivot of the pivot seat 7. All are positioned and assembled by key pins, so that the module bracket 2 can be rotated and installed. In addition, a bushing hole 50 is provided on the crescent-shaped gear 5, and a second bushing 22 is fitted into the bushing hole 50. The bushing hole 50, the second bushing 22, and the damping shaft 60 are coaxially assembled via key pins, enabling the module bracket 2 and the crescent-shaped gear 5 to grip the damping shaft 60 and rotate synchronously. This not only improves the consistency and stability of rotation but also simplifies the overall structure, makes assembly more convenient, and further saves assembly space, reducing the overall size of the lamp.

[0032] Of course, in the above design, the meshing of the drive gear 40 and the crescent-shaped gear 5 improves the stability of rotation and the accuracy of adjustment when the motor 4 drives the projection module 3 to rotate and adjust. In this embodiment, the resistance device 6 can be a damping spring shock absorber or a magnetic damper, achieving the effects of shock absorption, stabilization, and energy recovery. Through the design of the resistance device 6, it plays a role in stabilizing the projection module 3 during rotation, ensuring that the projection module 3 remains stable during adjustment, avoiding projection position deviation due to vibration or impact, and improving the stability and reliability of the projection lamp.

[0033] To improve the assembly stability of the crescent toothed gear 5, a positioning platform 23 is formed on the side wall of the module bracket 2 in this embodiment, and a positioning groove 51 is opened on the side of the crescent toothed gear 5. The crescent toothed gear 5 is positioned and engaged with the positioning platform 23 on the module bracket 2 through the positioning groove 51, and is locked and fixed by screws, thus ensuring the stability and consistency during rotation and preventing shaking.

[0034] To more precisely control and adjust the projection position, an angle sensor 8 is also installed on one side of the base 1 in this embodiment. A magnetic induction block 80 that senses the angle sensor 8 is fixed on the side of the module bracket 2 near the angle sensor 8. An arc-shaped hole 104 is also provided on the base 1 at the location where the angle sensor 8 is installed to avoid the magnetic induction block 80. The magnetic induction block 80 extends into the arc-shaped hole 104, close to the angle sensor 8, and moves with the rotation of the module bracket 2, sensing and providing feedback to the angle sensor 8. This feedback mechanism, achieved through the sensing between the angle sensor 8 and the magnetic induction block 80, ensures that the projection module 3 can be precisely adjusted according to different vehicle models and vehicle heights, improving the applicability and adjustment accuracy of the projection lamp.
