Technical Field
[0001] This utility model relates to the field of automotive seat back assembly technology, specifically an auxiliary tooling for automotive seat back assembly. Background Technology
[0002] With the rapid development of the automotive industry, consumers are increasingly demanding higher quality and comfort from car interiors. As a key component that comes into direct contact with passengers, the assembly precision and quality of car seats directly impact the passenger experience. The seat back, as an important part of the seat, requires a high degree of precision and stability in its assembly process to ensure the seat's comfort, safety, and reliability.
[0003] However, manual operation makes it difficult to precisely fix the position and posture of the backrest, which can easily lead to deviations in the assembly position of the backrest and other components, affecting the overall performance and appearance quality of the seat. For example, uneven gaps or insecure installation may occur at the connection between the backrest and the seat frame. This not only reduces the comfort of the seat but may also cause abnormal noises during vehicle operation and even affect the safety of the seat. Furthermore, car seat backrests typically have a certain weight and volume, and manually fixing the backrest for extended periods increases the labor intensity of workers, easily leading to worker fatigue, which in turn affects assembly efficiency and quality. Therefore, an auxiliary tooling for assembling car seat backrests is proposed to solve the above problems. Utility Model Content

The fixing frame on the left side is fixedly connected to the left side wall of the left fixing frame, and the fixing frame on the right side is fixedly connected to the right side wall of the right fixing frame.
[0010] Furthermore, the threaded block is slidably connected to the inner side of the corresponding fixed frame, and the height and width of the threaded block are equal to the height and width of the inner side of the fixed frame, respectively.
[0011] Furthermore, there are two connecting rods on both the left and right sides, with the two connecting rods on the same side located above and below the threaded rod, respectively.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 3 An auxiliary tooling for assembling a car seat backrest in this embodiment includes a base frame 1, and an auxiliary component for assisting the assembly of the backrest is provided on the top of the base frame 1.
[0023] Please see Figure 1 In this embodiment, the auxiliary components include two electric slide rails 2 fixedly connected to the top of the base frame 1. The moving part of the electric slide rail 2 is fixedly connected to the mounting shell 3. The inner bottom wall of the mounting shell 3 is fixedly connected to an electric push rod 4. The movable rod of the electric push rod 4 is fixedly connected to a fixed frame 5. Motors 6 are fixedly connected to opposite sides of the two fixed frames 5. The output shaft of the motor 6 is fixedly connected to a threaded rod 7. Threaded blocks 8 are threadedly connected to the outer side of the threaded rod 7. Connecting rods 9 are fixedly connected to opposite sides of the two threaded blocks 8. Connecting plate 10 is fixedly connected to the other end of the connecting rod 9. Elastic telescopic member 11 is fixedly connected to the other side of the connecting plate 10. Clamping block 12 is fixedly connected to the other end of the elastic telescopic member 11.
[0024] Specifically, two electric slide rails 2 are respectively arranged on the left and right sides of the top of the base frame 1.
[0025] It should be noted that this symmetrical arrangement ensures that forces are applied simultaneously from both sides of the car seat back during the subsequent assembly process.
[0026] Specifically, a fixing bracket 13 is fixedly connected to the outer side of the left and right motors 6. The left fixing bracket 13 is fixedly connected to the left side wall of the left fixing frame 5, and the right fixing bracket 13 is fixedly connected to the right side wall of the right fixing frame 5.
[0027] It should be noted that the function of the fixing frame 13 is to provide stable support for the motor 6 and prevent the motor 6 from shaking due to its own vibration or external forces during operation.
[0028] Specifically, the threaded block 8 is slidably connected to the inner side of the corresponding fixed frame 5, and the height and width of the threaded block 8 are equal to the height and width of the inner side of the fixed frame 5, respectively.
[0029] It should be noted that this design allows the threaded block 8 to move linearly along the axis of the threaded rod 7 within the fixed frame 5, without rotation or other directional deviations.
[0030] Specifically, there are two connecting rods 9 on each side, with the two connecting rods 9 on the same side located above and below the threaded rod 7, respectively.
[0031] It should be noted that the two connecting rods 9 can provide more stable support for the connecting plate 10 when the threaded block 8 drives the connecting plate 10 to move, so that the connecting plate 10 remains horizontal during the movement.
[0032] Specifically, the right side of the inner side of the left fixed frame 5 has two guide holes that are adapted to the connecting rod 9, and the left side of the inner side of the right fixed frame 5 has two guide holes that are adapted to the connecting rod 9.
[0033] It should be noted that the guide hole serves to guide and limit the movement of the connecting rod 9, preventing the connecting rod 9 from shifting or shaking during movement.
[0034] Specifically, there are four elastic telescopic components 11 on both the left and right sides. The four elastic telescopic components 11 on the left side are arranged at the four corners on the right side of the left connecting plate 10, and the four elastic telescopic components 11 on the right side are arranged at the four corners on the left side of the right connecting plate 10.
[0035] It should be noted that this multi-point arrangement enables the elastic telescopic component 11 to provide uniform elastic support force to the clamping block 12.
[0036] Specifically, each of the opposite side walls of the left and right clamping blocks 12 has an installation groove, and a pressure sensor 14 is fixedly connected to the inside of the installation groove. A rubber pad 15 is fixedly connected to the opposite side of each of the left and right clamping blocks 12.
[0037] It should be noted that the pressure sensor 14 can monitor the pressure applied by the clamp 12 to the back of the car seat in real time and feed the pressure data back to the control system so that the operator can accurately control the clamping force according to actual needs. The rubber pad 15 can increase the friction between the clamp 12 and the backrest, improve the stability of clamping, and protect the backrest surface to prevent the clamp 12 from making direct hard contact with the backrest and avoid scratching the backrest surface.
[0038] The working principle of the above embodiments is as follows:
[0039] Start the electric slide rail 2. The mover of the electric slide rail 2 drives the mounting housing 3 to move along the track of the electric slide rail 2, thereby adjusting the position of the fixed frame 5 in the horizontal direction. Next, start the electric push rod 4. The movable rod of the electric push rod 4 pushes the fixed frame 5 to move up and down in the vertical direction, so that the fixed frame 5 drives the clamping block 12 to a position that matches the height of the car seat back. Subsequently, start the motor 6. The output shaft of the motor 6 drives the threaded rod 7 to rotate. Since the threaded block 8 is threadedly connected to the threaded rod 7 and is slidably connected to the inside of the fixed frame 5, under the action of the rotation of the threaded rod 7, the threaded block 8 moves linearly along the axis of the threaded rod 7. The threaded block 8 drives the connecting rod. 9. The connecting plate 10, the elastic telescopic component 11, and the clamping block 12 move together toward the back of the car seat. As the clamping block 12 gradually approaches the backrest, the rubber pad 15 first contacts the surface of the backrest, providing cushioning and protection. As the threaded block 8 continues to move, the elastic telescopic component 11 is compressed, and the pressure sensor 14 begins to detect the pressure applied to the backrest by the clamping block 12. Based on the data fed back by the pressure sensor 14, the operator precisely controls the operation of the motor 6 through the control system to ensure that the clamping block 12 applies a suitable clamping force to the backrest, ensuring that the backrest is stably clamped. After the clamping block 12 stably clamps the backrest of the car seat, the operator can use auxiliary tools to assemble the backrest.
