[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This multi-angle adjustable in-vehicle auxiliary lighting device utilizes a dual-motor collaborative drive architecture to achieve multi-dimensional precise control through its adjustable structure. The first motor drives a rotating frame via a meshing transmission gear and an incomplete gear to achieve basic angle adjustment. The second motor drives a rotating plate via a two-stage reduction transmission of a rotating gear and a rotary gear to fine-tune the illumination direction. The two transmission systems achieve a wide range of stepless adjustment of the lighting angle through mechanical linkage. The gear transmission system adopts industrial-grade precision machining standards, with meshing clearance controlled at the micron level to ensure the accuracy of angle adjustment and smooth operation. The special tooth profile design of the incomplete gear expands the adjustment range and avoids transmission dead points. The bearing fit structure between the rotating shaft and the support frame effectively reduces friction loss, enabling the system to maintain long-term stability even under frequent adjustments. This solution efficiently transforms the motor rotational motion into multi-dimensional angle adjustment through modular mechanical design, meeting the precise positioning requirements in complex lighting scenarios and ensuring absolute fixation of the working state through the gear self-locking characteristic, significantly improving the practicality and reliability of the lighting system.

[0016] 2. This multi-angle adjustable in-vehicle auxiliary lighting device, through a fixed structure, allows the rotating plate to rotate under control. The rotating shaft drives the active gear, which in turn drives the bidirectional transmission rack to achieve symmetrical displacement. Rapid positioning is achieved through the rigid connection between the moving frame and the support plate. The buffer design of the first spring effectively absorbs contact impact, and the sliding fit of the guide rod ensures displacement accuracy. The mechanical interlocking structure of the limiting shaft and the limiting hole forms a rigid constraint, eliminating the risk of vibration displacement during operation. The position adjustment mechanism adopts a spring-locking design. The moving rod achieves instantaneous release and automatic reset of the sliding block through the elastic energy storage of the second spring. The precise fit between the guide rail and the locking hole ensures positioning reliability. The entire system integrates the precision of gear transmission, the buffering effect of elastic elements, and the stability of mechanical interlocking, meeting the multi-dimensional adjustment needs of the lighting position. The dual locking mechanism ensures long-term operational reliability. Its modular design significantly improves maintenance convenience, and the precise movement of the kinematic pairs makes operation smooth and accurate. Attached Figure Description

The guide frame 306 is mounted inside the fixed frame 1. The transmission block 307 is movably mounted on the guide frame 306. The transmission rack 308 is mounted on the transmission block 307 and meshes with the driving gear 305. The movable frame 309 is mounted on the transmission block 307, and one end of the movable frame 309 penetrates the side wall of the fixed frame 1. The guide rod 311 is movably mounted on the movable frame 309. The abutment plate 312 is mounted on the fixed frame 1. On the guide rod 311, the first spring 313 is mounted on the movable frame 309 and connected to the abutment plate 312. The guide rail 314 is mounted on the fixed frame 1. The locking hole 315 is provided on the guide rail 314. The sliding block 316 is movably mounted on the guide rail 314. The work box 317 is mounted on the sliding block 316. The sliding plate 318 is movably mounted inside the work box 317. The moving rod 319 is mounted on the sliding plate 318, and one end of the moving rod 319 away from the sliding plate 318 passes through the side wall of the work box 317. The second spring 320 is mounted on the guide rod 311. The sliding plate 318 and the second spring 320 abut against the inner wall of the work box 317. The transmission rod 321 is mounted on the sliding plate 318, and the end of the transmission rod 321 away from the sliding plate 318 passes through the side wall of the work box 317. A pair of guide frames 306, transmission blocks 307, transmission racks 308, moving frames 309, abutment plates 312, and first springs 313 are provided. Several guide rods 311 are provided, all symmetrically arranged. When the lighting lamp 4 needs to be turned on, the rotating plate 303 is manually operated to make it rotate around the rotating shaft 301. Due to the rigid connection characteristics, the rotating shaft 301 rotates synchronously and drives the drive gear 305 to rotate accordingly. The drive gear 305 drives a pair of transmission racks 308 to move linearly in opposite directions through precise meshing transmission. Under the constraint of the guide mechanism formed by the transmission block 307 and the guide frame 306, the transmission racks 308 achieve smooth linear displacement, thereby pulling a pair of moving frames 309 to move synchronously.The movable frame 309 drives the abutment plate 312 to abut against the side walls of the carriage. During this process, the first spring 313 is compressed and deformed, playing a buffering and shock-absorbing role, effectively mitigating the contact impact force. At the same time, the guide rod 311 slides on the movable frame 309 following the abutment plate 312 to complete the position adaptation; the limiting shaft 304 is precisely inserted through the side wall of the rotating plate 303 and embedded in the corresponding limiting hole 302 to form a mechanical locking structure. Through this double limiting mechanism, a stable support is provided for the rotating shaft 301, effectively preventing the fixed frame 1 from shifting due to vibration or external force during equipment operation, ensuring the structural stability and reliability of the lighting lamp 4 in the working state. When it is necessary to adjust the position of the lighting lamp 4, the movable rod 319 is pulled, and the movable rod 319 can drive the sliding plate 31 8 moves within the working box 317, compressing the second spring 320. The sliding plate 318 can drive the transmission rod 321 away from the locking hole 315 on the guide rail 314. At this time, the position of the sliding block 316 on the guide rail 314 can be adjusted, thereby adjusting the position of the lighting lamp 4. After adjustment, the moving rod 319 is released, the second spring 320 returns to its original position, and the second spring 320 drives the sliding plate 318 to move. Under the action of the sliding plate 318, the transmission rod 321 moves into the locking hole 315 on the guide rail 314, thereby fixing the sliding block 316 and stabilizing the lighting lamp 4 during operation.

[0028] Furthermore, the limiting shaft 304 is adapted to the limiting hole 302, and the rotating plate 303 is provided with anti-slip texture. The adapted limiting shaft 304 is fixed and stable in the limiting hole 302. The anti-slip texture increases the friction for the operator to use the rotating plate 303, making it easier to rotate the rotating plate 303.

[0029] Furthermore, the movable frame 309 is provided with a telescopic rod 310, and a plurality of limiting holes 302 are provided. The fixed end of the telescopic rod 310 is installed on the movable frame 309, and the movable end of the telescopic rod 310 is connected to the movable frame 309. The telescopic rod 310 can stabilize the movable frame 309 when it moves. The plurality of limiting holes 302 facilitate the use of the limiting shaft 304 to limit the rotation shaft 301 at different positions.

[0030] Furthermore, the transmission block 307 is adapted to the guide frame 306, and the end of the moving rod 319 away from the sliding plate 318 is provided with a pull plate. The adapted transmission block 307 slides stably on the guide frame 306, and the pull plate facilitates the movement of the moving rod 319.

[0031] Working principle: When the lighting lamp 4 needs to be activated, the rotating plate 303 is manually operated to rotate around the rotating shaft 301. Due to the rigid connection characteristics, the rotating shaft 301 rotates synchronously and drives the drive gear 305 to rotate accordingly. The drive gear 305 drives a pair of transmission racks 308 to move linearly in opposite directions through precise meshing transmission. Under the constraint of the guiding mechanism formed by the transmission block 307 and the guide frame 306, the transmission racks 308 achieve smooth linear displacement, thereby pulling a pair of moving frames 309 to move synchronously. The moving frames 309 drive the abutment plate 312 to come into close contact with the side walls of the carriage. During this process, the first spring 313 is compressed and deformed, playing a buffering and shock-absorbing role, effectively mitigating the contact impact force. Meanwhile, the guide rod 311 slides along the abutment plate 312 on the movable frame 309 to complete the position adaptation; the limiting shaft 304 is precisely inserted through the side wall of the rotating plate 303 and embedded in the corresponding limiting hole 302 to form a mechanical locking structure. Through this double limiting mechanism, a stable support is provided for the rotating shaft 301, effectively preventing the fixed frame 1 from shifting due to vibration or external force during equipment operation, ensuring the structural stability and reliability of the lighting lamp 4 in working condition. When the position of the lighting lamp 4 needs to be adjusted, the moving rod 319 is pulled. The moving rod 319 can drive the sliding plate 318 to move within the work box 317, compressing the second spring 320. The sliding plate 318 can drive the transmission rod 321 away from the locking hole 315 on the guide rail 314. At this time, the position of the sliding block 316 on the guide rail 314 can be adjusted, thereby adjusting the position of the lighting lamp 4. After adjustment, the moving rod 319 is released. Rod 319 resets the second spring 320, which in turn moves the sliding plate 318. Under the action of the sliding plate 318, the transmission rod 321 moves into the locking hole 315 on the guide rail 314, thereby fixing the sliding block 316 and stabilizing the lighting lamp 4 during operation. When the angle of the lighting lamp 4 needs to be adjusted, the first motor 204 is driven, which drives the transmission gear 205 to rotate. The incomplete gear 203, under the action of the transmission gear 205, drives the rotating frame 202 to rotate on the support frame 201, thereby adjusting the angle of the lighting lamp 4. The second motor 209 is driven, which drives the rotating gear 210 to rotate. The rotating gear 210 drives the rotating gear 208 to rotate. The rotating plate 207 follows the rotating gear 208 and rotates on the rotating frame 202 through the rotating shaft 206, further adjusting the angle of the lighting lamp 4.
