Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an automotive seat slide rail assembly. Background Technology

[0002] In the automotive manufacturing industry, the car seat slide rail assembly, as a key component for adjusting seat position, directly affects the user's riding experience and the overall quality of the vehicle due to its structural rationality and performance stability. Among these components, the bridge bracket, as a crucial part connecting the two slide rail assemblies and housing the slide rail motor, has always been a focus of research in this field due to its design and manufacturing process. Traditionally, the bridge bracket in car seat slide rail assemblies commonly uses plastic parts, such as… Figure 1 As shown. While plastic parts offer certain advantages in molding, they also present several significant drawbacks during manufacturing. First, plastic parts have relatively low strength, making them prone to deformation and even damage under complex vibration and stress environments during vehicle operation. This affects the structural stability and lifespan of the entire seat rail assembly. Second, to ensure sufficient strength, the plastic bridge bracket often needs to be designed to be thick, increasing material costs and occupying considerable space for seat height arrangement. This restricts the vertical layout of the seat, hindering the optimal design of the vehicle's interior space. Furthermore, manufacturing plastic parts typically requires mold making, which is costly to develop and results in a relatively high scrap rate, further increasing manufacturing costs. Traditional methods for installing the rail motor also have significant shortcomings. In the traditional approach, the rail motor is fixed to the pre-drilled mounting holes on the bridge bracket by the deformation of the plastic part. This installation method suffers from poor stability; under vibration and impact during vehicle operation, the rail motor is prone to vertical movement within the mounting holes. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model aims to provide an automotive seat slide rail assembly with a bridge bracket that has higher strength, occupies less space, and has lower cost. Furthermore, the installation stability between the slide rail motor and the bridge bracket is better, which can effectively improve the overall performance and reliability of the automotive seat slide rail assembly.

[0004] To achieve the above objectives, this utility model proposes an automotive seat slide rail assembly, including two slide rail components arranged opposite to each other, a bridge bracket connecting the two slide rail components, and a slide rail motor mounted on the bridge bracket. The bridge bracket is a sheet metal part, and the bridge bracket has a recessed design at the position corresponding to the slide rail motor to form a groove. Two vertical clamping plates with upward openings are arranged at intervals on the left and right sides in the groove. The protruding parts at both ends of the slide rail motor are tightly clamped in the two vertical clamping plates, thereby limiting and fixing it in the two vertical clamping plates in the front and rear. The two ends of the slide rail motor are also respectively attached to the inner walls of the two vertical clamping plates, thereby limiting and fixing it in the left and right sides between the two vertical clamping plates. When the slide rail motor is installed in the two vertical clamping plates, the upper end of the vertical clamping plate is bent to the left or right to abut against the upper end face of the slide rail motor, so as to limit and fix the slide rail motor in the two vertical clamping plates in the upper and lower sides.

[0005] In the above solution: the protruding portions at both ends of the slide rail motor are T-shaped, forming T-shaped ends. The rods of the T-shaped ends are clamped in the vertical clamping plate, and the heads of the T-shaped ends abut against the inner wall of the vertical clamping plate. The rods of the T-shaped ends clamped in the vertical clamping plate can effectively limit the slide rail motor in the front-back direction, preventing the slide rail motor from moving back and forth due to inertia and other factors during slide rail operation. The outward abutment of the heads of the T-shaped ends against the inner wall of the vertical clamping plate further restricts the displacement of the slide rail motor in the left-right direction. This multi-directional limiting design makes the installation of the slide rail motor in the vertical clamping plate more stable.

[0006] In the above solution: the openings of the two vertical clamping plates are a "U"-shaped opening and an "O"-shaped opening, respectively. The two ends of the slide rail motor are clamped in the "U"-shaped opening and the "O"-shaped opening, respectively. The "O"-shaped opening prevents the corresponding end of the slide rail motor from coming off upwards. During installation, the corresponding end of the slide rail motor needs to be inserted into the "O"-shaped opening from the side, and then the other end of the slide rail motor needs to be pressed downwards into the "U"-shaped opening. The side insertion of the "O"-shaped opening and the downward pressing of the "U"-shaped opening are simple and straightforward, requiring no complicated tools or operating skills, reducing the debugging and adjustment time during the installation process, simplifying the entire installation process, and helping to improve the assembly speed of the production line.

[0007] In the above scheme: the upper ends of the two vertical clamps are bent in the same direction, the vertical clamp where the "U"-shaped opening is located is bent to abut against the upper end face of the slide rail motor, and the vertical clamp where the "O"-shaped opening is located is bent to abut against the rod of the T-shaped end, forming limiting points in both the upper and lower directions, effectively preventing the slide rail motor from moving up and down.

[0008] In the above scheme: the vertical clamp and the bridge support are an integral structure, which can be formed by setting a "U"-shaped tear on the bridge support and bending it upward.

[0009] In the above scheme: the slide rail motor is a dual-axis motor, both ends of the bridge bracket are provided with outward-facing "U"-shaped notches, and the top surfaces of the two slide rail assemblies are provided with abutment posts. The "U"-shaped notches on both sides abut against the abutment posts on the corresponding sides, thereby limiting and fixing the bridge bracket between the two slide rail assemblies.

[0010] When the output shaft of the slide rail motor extends to the left or right, it first passes through the platform on the bridge bracket from the front to the back of the bridge bracket, and then connects to the gearbox of the slide rail assembly. The front of the bridge bracket is provided with a "U"-shaped support frame for supporting the output shaft. Therefore, this structural design has a certain downward limiting effect on the bridge bracket, which can prevent the bridge bracket from coming off upward. This structure, together with the aforementioned "U"-shaped notch and abutment post, can achieve stable fixation of the bridge bracket.

[0011] The beneficial effects of this utility model are:

[0012] 1. By setting a recessed groove at the position of the slide rail motor on the bridge bracket, and installing two vertical clamps in the groove, the slide rail motor is limited and fixed from multiple directions (front-back, left-right, top-bottom) to ensure stable installation on the bridge bracket. This effectively prevents the slide rail motor from shaking or shifting during use, improving the overall stability and reliability of the car seat slide rail assembly. 2. Using sheet metal parts as the bridge bracket offers advantages such as high strength, light weight, and easy processing, reducing overall weight while maintaining structural strength. 3. The thinner sheet metal parts occupy less space in the seat's height arrangement, facilitating a more rational layout of the car's interior space. 4. The vertical clamp design simplifies the installation process of the slide rail motor. Simply clamp the protruding parts at both ends of the slide rail motor tightly into the two vertical clamps, and then bend the upper ends of the vertical clamps to abut against the upper surface of the slide rail motor. This completes the installation and fixation of the slide rail motor, simplifying the operation and improving assembly efficiency. Attached Figure Description

[0015] Figure 3 This is a schematic diagram of the bridge support structure.

[0016] Figure 4 This is a schematic diagram of the installation of the slide rail motor on the bridge support. Detailed Implementation

[0017] like Figure 2As shown in Figure 4, an automotive seat slide rail assembly mainly consists of two slide rail components 1 arranged opposite to each other, a bridge bracket 2 connecting the two slide rail components 1, and a slide rail motor 3 mounted on the bridge bracket 2.

[0018] The bridge support 2 is a sheet metal part. The bridge support 2 is designed with a recessed groove 21 at the position corresponding to the slide rail motor 3. Two vertical clamping plates 22 with openings facing upwards are arranged in the groove 21 at intervals on the left and right. The protruding parts at both ends of the slide rail motor 3 are tightly clamped in the two vertical clamping plates 22, thereby limiting and fixing it in the two vertical clamping plates 22 in the front and back. The two ends of the slide rail motor 3 are also respectively attached to the inner wall of the two vertical clamping plates 22, thereby limiting and fixing it in the left and right between the two vertical clamping plates 22.

[0019] After the slide rail motor 3 is installed in the two vertical clamping plates 22, the upper end of the vertical clamping plate 22 is bent to the left or right until it abuts against the upper end face of the slide rail motor 3, so as to fix the slide rail motor 3 in the two vertical clamping plates 22 for upper and lower limit.

[0020] Ideally, the protruding portions at both ends of the slide rail motor 3 are T-shaped, forming T-shaped ends 31. The rod of the T-shaped end 31 is clamped in the vertical clamping plate 22, and the head of the T-shaped end 31 abuts against the inner wall of the vertical clamping plate 22 outward. The rod of the T-shaped end 31 clamped in the vertical clamping plate 22 can effectively limit the slide rail motor 3 in the front-back direction, preventing the slide rail motor 3 from moving back and forth due to inertia and other factors during the operation of the slide rail. The head of the T-shaped end 31 abuts against the inner wall of the vertical clamping plate 22 outward, further limiting the displacement of the slide rail motor 3 in the left-right direction. This multi-directional limiting design makes the installation of the slide rail motor 3 in the vertical clamping plate 22 more stable.

[0021] Ideally, the openings of the two vertical clamping plates 22 are a "U"-shaped opening a and an "O"-shaped opening b, respectively, and the two ends of the slide rail motor 3 are clamped in the "U"-shaped opening a and the "O"-shaped opening b, respectively. The "O"-shaped opening b can prevent the corresponding ends of the slide rail motor 3 from coming off upward.

[0022] During installation, the corresponding end of the slide rail motor 3 needs to be inserted from the side into the "O"-shaped opening b, and then the other end of the slide rail motor 3 needs to be pressed downward into the "U"-shaped opening a. The side insertion of the "O"-shaped opening b and the downward pressing of the "U"-shaped opening a are simple and straightforward, requiring no complicated tools or operating skills. This reduces the debugging and adjustment time during the installation process, simplifies the entire installation process, and helps to improve the assembly speed of the production line.

[0023] Ideally, the upper ends of the two vertical clamping plates 22 are bent in the same direction. The vertical clamping plate 22 where the "U"-shaped opening a is located is bent to abut against the upper end face of the slide rail motor 3, and the vertical clamping plate 22 where the "O"-shaped opening b is located is bent to abut against the rod part of the T-shaped end 31, forming limiting points in both the upper and lower directions, effectively preventing the slide rail motor 3 from moving up and down.

[0024] Ideally, the vertical clamp 22 and the bridge support 2 should be an integral structure, which can be formed by setting a "U"-shaped tear on the bridge support 2 and bending it upward.

[0025] Ideally, the slide rail motor 3 is a dual-axis motor, and both ends of the bridge bracket 2 are provided with outward-facing "U"-shaped notches 23. Both slide rail assemblies 1 are provided with abutment posts 11 on their top surfaces. The "U"-shaped notches 23 on both sides abut against the abutment posts 11 on the corresponding sides, thereby limiting and fixing the bridge bracket 2 between the two slide rail assemblies 1.

[0026] When the output shaft of the slide rail motor 3 extends to the left and right, it first passes through the platform on the bridge bracket 2 from the front to the back of the bridge bracket 2, and then connects with the gearbox of the slide rail assembly 1. The front of the bridge bracket 2 is provided with a "U"-shaped support frame for supporting the output shaft. Therefore, this structural design has a certain downward limiting effect on the bridge bracket 2, which can prevent the bridge bracket 2 from coming off upward. This structure, together with the "U"-shaped notch 23 and the abutment post 11, can achieve stable fixation of the bridge bracket 2.
