Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to an installation and positioning structure for automobile taillights. Background Technology

[0002] The mounting and positioning structure of automotive taillights plays a crucial role in vehicle design, primarily ensuring the stable installation and accurate positioning of the taillights at the rear of the vehicle. With the development of the automotive industry, the function of taillights has expanded beyond simply providing nighttime illumination to include brake warning, turn signals, and reversing lights, among other functions. The design of the taillight positioning structure directly affects the proper functioning of these features and the aesthetic appeal of the vehicle's exterior.

[0003] Traditional taillight installation typically relies on manual adjustment and fixing. Due to errors in manual operation, the connection between the taillight and the vehicle body may not be tight enough, making it prone to loosening or even detachment during vehicle operation due to vibration or impact, affecting driving safety. In addition, manual operation makes it difficult to ensure that the installation position and angle of each taillight are consistent, affecting the stability of product quality. Furthermore, the angle adjustment of traditional taillights usually depends on manual adjustment, which requires repeated attempts and calibrations, making the operation complex and time-consuming. It is particularly inefficient in scenarios requiring precise angle matching. At the same time, manual adjustment makes it difficult to control the slight changes in angle, which can easily lead to deviations in the illumination angle of the taillights, affecting the lighting effect and safety. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an installation and positioning structure for automobile taillights.

[0005] This utility model is achieved using the following technical solution: a mounting and positioning structure for a car taillight, comprising a mounting housing, a fixing housing fixedly connected to the top of the mounting housing, a mounting plate fixedly connected to the top of the mounting housing, and a sliding groove formed on the top of the mounting housing, and further comprising:

[0006] An adjustment mechanism, comprising an electric push rod fixedly connected to the right side of the mounting plate, and a rotating housing rotatably connected inside the mounting housing;

[0007] The positioning mechanism includes a limiting sleeve fixedly connected inside the rotating housing, a moving block slidably connected inside the limiting sleeve, and an insert block fixedly connected to the left side of the moving block.

[0008] As a further improvement to the above solution, a connecting block is fixedly connected to the right end of the electric push rod, a rack is fixedly connected to the front of the connecting block, a sliding block is fixedly connected to the bottom of the rack, a rotating column is fixedly connected to the top of the rotating housing, and a gear is fixedly connected to the outside of the rotating column.

[0009] Through the above technical solution, the cooperation between the electric push rod and the gear and rack mechanism transforms linear motion into rotational motion, simplifies the mechanical structure of angle adjustment, improves transmission efficiency and stability, and avoids the cumbersome operation of traditional manual adjustment.

[0010] As a further improvement to the above solution, the rack and gear mesh with each other, the sliding block is slidably connected inside the sliding groove, and the rotating column is rotatably connected inside the mounting housing.

[0011] Through the above technical solution, the cooperation between the sliding groove and the sliding block restricts the movement trajectory of the rack, prevents rack deviation caused by external force or error, ensures precise meshing of gear and rack, and improves the accuracy and reliability of angle adjustment.

[0012] As a further improvement to the above solution, a connecting shell is fixedly connected to the back of the rotating shell, a servo motor is fixedly connected to the left side of the connecting shell, a first transmission column is fixedly connected to the output end of the servo motor, and a first bevel gear is fixedly connected to the outside of the first transmission column.

[0013] Through the above technical solution, the cooperation between the servo motor and the bevel gear set provides stable power output and precise transmission ratio, ensuring the accurate insertion of the insert during the taillight fixing process and avoiding problems of insecure fixing caused by insufficient power or transmission error.

[0014] As a further improvement to the above solution, a rotating disk is rotatably connected inside the limiting sleeve, a guide block is fixedly connected inside the limiting sleeve, a sliding column is slidably connected inside the rotating disk, and a second transmission column is fixedly connected inside the rotating disk.

[0015] Through the above technical solution, the cooperation between the guide block and the sliding column ensures the linear movement of the sliding column inside the rotating disk, avoiding the offset of the insertion block caused by shaking or tilting, and improving the accuracy and stability of the taillight fixing.

[0016] As a further improvement to the above solution, a second bevel gear is fixedly connected to the outside of the second transmission column, a limit post is inserted into the inside of the limit sleeve, and a taillight is fixedly connected to the front of the limit post.

[0017] Through the above technical solution, the cooperation between the second bevel gear and the second transmission column transmits the power of the servo motor to the inside of the limiting sleeve, ensuring that the insert block is firmly fixed to the limiting column, and enhancing the vibration resistance and safety of the taillight.

[0018] As a further improvement to the above solution, the first bevel gear and the second bevel gear mesh with each other, the sliding column is slidably connected inside the guide block, the moving block is rotatably connected outside the sliding column, and the second transmission column is rotatably connected inside the rotating housing.

[0019] Through the above technical solution, the meshing of the bevel gear set and the cooperation of the guide block ensure the accuracy of power transmission and the positioning accuracy of the insert, avoiding fixing failure caused by transmission error or shaking, and improving the installation reliability of the taillight.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention uses a servo motor to drive the operation of the first transmission column, which in turn drives the meshing transmission of the first and second bevel gears, thereby achieving synchronous rotation of the second transmission column. This structural operation is further transformed into the rotation of a rotating disk, which guides the sliding column to move inward through a guide block. Ultimately, the moving block slides smoothly within the limiting sleeve, allowing the insert to be accurately inserted into the limiting column. This achieves rapid fixing of the taillight without the need for manual adjustment, improving installation efficiency and accuracy. At the same time, the cooperation between the guide block and the sliding column ensures stable insertion of the insert, avoiding problems of insecure fixing caused by shaking or errors, and enhancing the installation stability and reliability of the taillight.

[0022] This invention utilizes the telescopic movement of an electric push rod to drive the linear motion of the connecting block and rack. The meshing transmission between the rack and gear further drives the rotating housing to rotate clockwise. The linkage design between the electric push rod and the rack enables precise adjustment of the taillight angle. The operation is simple and the adjustment range is controllable. The cooperation between the gear and the rotating housing ensures the smoothness and stability of the angle adjustment, avoiding the cumbersome and error-prone nature of traditional manual adjustment, and improving the practicality and safety of the taillight.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0032] Example:

[0033] Please combine Figure 1-6 This embodiment of a car taillight mounting and positioning structure includes a mounting housing 1, a fixing housing 11 fixedly connected to the top of the mounting housing 1, a mounting plate 12 fixedly connected to the top of the mounting housing 1, and a sliding groove 13 formed on the top of the mounting housing 1. It also includes:

[0034] Adjustment mechanism 2 includes an electric push rod 201 fixedly connected to the right side of the mounting plate 12, and a rotating housing 205 rotatably connected inside the mounting housing 1;

[0035] The positioning mechanism 3 includes a limiting sleeve 305 fixedly connected inside the rotating housing 205, a moving block 309 slidably connected inside the limiting sleeve 305, and an insert block 3010 fixedly connected to the left side of the moving block 309.

[0036] A connecting block 202 is fixedly connected to the right end of the electric push rod 201. A rack 203 is fixedly connected to the front of the connecting block 202. A sliding block 204 is fixedly connected to the bottom of the rack 203. A rotating column 206 is fixedly connected to the top of the rotating housing 205. A gear 207 is fixedly connected to the outside of the rotating column 206.

[0037] The rack 203 meshes with the gear 207, the sliding block 204 is slidably connected inside the sliding groove 13, and the rotating column 206 is rotatably connected inside the mounting housing 1.

[0038] A connecting housing 301 is fixedly connected to the back of the rotating housing 205. A servo motor 302 is fixedly connected to the left side of the connecting housing 301. A first transmission column 303 is fixedly connected to the output end of the servo motor 302. A first bevel gear 304 is fixedly connected to the outside of the first transmission column 303.

[0039] The limiting sleeve 305 is rotatably connected to a rotating disk 306, the limiting sleeve 305 is fixedly connected to a guide block 307, the rotating disk 306 is slidably connected to a sliding column 308, and the rotating disk 306 is fixedly connected to a second transmission column 3011.

[0040] The second transmission column 3011 is externally fixedly connected to the second bevel gear 3012, and the limiting sleeve 305 is internally inserted with the limiting column 3013. The front of the limiting column 3013 is fixedly connected to the taillight 3014.

[0041] The first bevel gear 304 and the second bevel gear 3012 mesh with each other. The sliding column 308 is slidably connected inside the guide block 307. The moving block 309 is rotatably connected outside the sliding column 308. The second transmission column 3011 is rotatably connected inside the rotating housing 205.

[0042] The implementation principle of the installation and positioning structure of a car taillight in this embodiment is as follows: During the installation process, the operator only needs to insert the limiting post 3013 into the inside of the limiting sleeve 305. This simple action lays the foundation for the subsequent fixing operation. Then, the servo motor 302 is started. As a power source, it drives the first transmission post 303 to rotate clockwise. This rotational motion is transmitted through the meshing of the first bevel gear 304 and the second bevel gear 3012, thereby driving the second transmission post 3011 to rotate synchronously. The rotation of the second transmission post 3011 is further converted into the rotation of the rotating disk 306. The sliding post 308 inside the rotating disk 306 moves inward under the guidance of the guide block 307. During this process, the moving block 309 slides smoothly inside the limiting sleeve 305 and drives the insert block 3010 to accurately insert into the inside of the limiting post 3013, thereby completing the firm fixing of the taillight 3014.

[0043] When the angle of the taillight 3014 needs to be adjusted, the electric push rod 201 is activated. Its extension and retraction action is transmitted to the rack 203 through the connecting block 202. The rack 203 moves straight to the right under the action of the sliding block 204 and meshes with the gear 207 on the top of the rotating housing 205, driving the gear 207 to rotate clockwise. This rotational motion then drives the rotating housing 205 to rotate clockwise as a whole, thereby achieving precise adjustment of the angle of the taillight 3014.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
