Description

Technical Field

[0001] This utility model belongs to the field of automotive seat manufacturing technology, and relates to an assembly fixture for automotive seats. Background Technology

[0002] For the sake of spatial flexibility and functional expansion, existing car rear seats usually adopt a split design. The split design of the car rear seat includes a seat cushion frame and a backrest frame. The backrest frame includes a left backrest frame and a right backrest frame. The left backrest frame and the right backrest frame are independently hinged to the seat cushion frame, so that the left backrest frame and the right backrest frame can rotate independently relative to the seat cushion frame.

[0003] However, the split design of the rear seats in cars increases the difficulty of assembling the seat cushion frame and backrest frame. When assembling the left and right backrest frames with the seat cushion frame, the angles between the left and right backrest frames and the seat cushion frame are often inconsistent. In other words, after the left and right backrest frames are assembled with the seat cushion frame, there is a step difference between the front and rear, making the assembly of the left and right backrest frames with the seat cushion frame time-consuming and laborious. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an assembly fixture for automotive seats. The technical problem this invention aims to solve is how to improve the assembly efficiency of the left and right backrest frames with the seat cushion frame.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An assembly fixture for an automobile seat includes a workbench, characterized in that a plurality of positioning blocks are fixedly connected to the top of the workbench, the top of each positioning block has a positioning post, a fixed frame that is inclined backward is also fixedly connected to the workbench, and a support frame is connected to the top of the fixed frame. The support frame is inverted L-shaped and can rotate back and forth relative to the fixed frame and be locked.

[0007] The assembly fixture for this car seat uses positioning posts on a workbench to position the seat cushion frame, while an inverted L-shaped support frame supports both backrest frames and adjusts the angle between them. The vertical and horizontal parts of the inverted L-shaped support frame form a rigid angle. When the horizontal end is subjected to force, the resulting bending moment is effectively transferred to the vertical part through this angle. This allows the inverted L-shaped support frame to effectively resist bending deformation caused by cantilever loads, preventing excessive bending of the support downwards or upwards and ensuring the stability of the support. This overcomes the problem of a step difference between the front and rear of the backrest frames and the seat cushion frame after assembly, thereby improving the assembly efficiency of the left and right backrest frames with the seat cushion frame.

[0008] In the aforementioned assembly fixture for an automotive seat, two angle adjusters are installed on the bottom sides of the support frame. These two angle adjusters are fixedly connected to the top sides of the fixed frame via mounting plates. A linkage shaft for synchronously rotating the two angle adjusters is threaded through each adjustment. An angle adjustment motor is also installed on the support frame. The output end of the angle adjustment motor passes through the linkage shaft and is fixedly connected, snapped, or engaged with it to drive the linkage shaft to rotate. This allows the support frame to rotate more effectively relative to the fixed frame.

[0009] In the aforementioned assembly fixture for an automotive seat, a clamping block is further provided on the worktable. The clamping block and at least one positioning block are located in front of the fixing frame. The clamping block is positioned directly above the positioning block and offset from the positioning post. The clamping block can move up and down relative to the positioning block. This allows for better positioning of the seat cushion frame and prevents displacement of the seat cushion frame during assembly.

[0010] In the aforementioned assembly fixture for an automotive seat, a cylinder with a vertically oriented output shaft is fixedly connected to the worktable, and a swing arm is hinged to it. One end of the swing arm is hinged to the output shaft of the cylinder, and the other end of the swing arm is fixedly connected to the clamping block. This structure allows the up-and-down movement of the clamping block to be controlled by the up-and-down movement of the cylinder's output shaft, thereby better driving the clamping block to press against or disengage from the seat cushion frame's support legs, facilitating the positioning and placement of the seat cushion frame.

[0011] In the aforementioned assembly fixture for an automotive seat, there are two positioning blocks and two clamping blocks located in front of the fixing frame, with positioning pins on the positioning blocks positioned between the two clamping blocks. This allows for better positioning of the seat cushion frame, preventing displacement of the seat cushion frame during assembly.

[0012] Compared with existing technologies, the advantages of this automotive seat assembly fixture are as follows: This automotive seat assembly fixture uses positioning posts on the worktable to position the seat cushion frame, and simultaneously uses a support frame to support and adjust the angle between the two backrest frames and the seat cushion frame. This overcomes the problem of a step difference between the front and rear sides after the two backrest frames are assembled with the seat cushion frame, thereby improving the assembly efficiency of the left and right backrest frames with the seat cushion frame. Furthermore, the vertical and horizontal parts of the inverted L-shaped support frame form a rigid angle. When the end of the horizontal part is subjected to force, the resulting bending moment is effectively transferred to the vertical part through this angle. This allows the inverted L-shaped support frame to effectively resist bending deformation caused by cantilever loads, preventing excessive downward or upward bending of the support and ensuring the stability of the support.

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] An assembly fixture for a car seat, referring to Figure 1-5 The system includes a workbench 1, with several positioning blocks 2 fixedly connected to the top of the workbench 1. Each positioning block 2 has a positioning post 2a on its top. A fixed frame 3 that is tilted backward is also fixedly connected to the workbench 1. A support frame 4 is also connected to the top of the fixed frame 3. The support frame 4 is inverted L-shaped and can rotate back and forth relative to the fixed frame 3 and be locked.

[0021] Reference Figure 1 and Figure 3 Specifically, the support frame 4 has two angle adjusters 5 installed on its bottom sides respectively. The two angle adjusters 5 are fixed to the top sides of the fixed frame 3 by mounting plates. The two angle adjusters 5 are simultaneously connected to a linkage shaft 6 for driving the two angle adjusters 5 to rotate synchronously. The support frame 4 is also equipped with an angle adjusting motor 7. The output end of the angle adjusting motor 7 is connected to the linkage shaft 6 and fixedly connected, snapped or engaged with the linkage shaft 6 to drive the linkage shaft 6 to rotate.

[0022] Reference Figure 1 , Figure 2 and Figure 3Furthermore, the workbench 1 is also provided with a clamping block 8. The clamping block 8 and at least one positioning block 2 are respectively located in front of the fixed frame 3. The clamping block 8 is located directly above the positioning block 2 and is offset from the positioning post 2a. The clamping block 8 can move up and down relative to the positioning block 2. Specifically, the workbench 1 is fixedly connected to a cylinder 9 with its output shaft arranged vertically and a swing arm 11 is hinged to it via a hinge 10. One end of the swing arm 11 is hinged to the output shaft of the cylinder 9, and the other end of the swing arm 11 is fixedly connected to the clamping block 8.

[0023] In this embodiment, it is preferred that there are two positioning blocks 2 and two clamping blocks 8 located in front of the fixing frame 3, and the positioning posts 2a on the two positioning blocks 2 are located between the two clamping blocks 8.

[0024] The following describes the working principle of the assembly fixture for this car seat:

[0025] During assembly, the operator first places the car seat cushion frame on the workbench 1. The bottom of the car seat cushion frame has four support legs, each with mounting holes for connecting to the car's interior floor. The mounting holes of the four support legs are simultaneously fitted onto the positioning posts 2a of the positioning blocks 2 on the front and rear sides of the workbench 1, so that the positioning posts 2a limit the movement of the support legs. Then, the cylinder 9 drives the swing arm 11 to move upward, and the other end of the swing arm 11 moves downward, causing the clamping block 8 to press the support legs (see reference). Figure 4 At this point, the positioning of the car seat cushion frame is completed;

[0026] Next, the operator rotatably connects the inner side of the bottom of the left backrest frame to the car seat cushion frame, and pre-connects the outer side to the car seat cushion frame with bolts and nuts. At the same time, the backrest frame is pressed against the support frame 4. Then, the operator rotatably connects the inner side of the bottom of the right backrest frame to the car seat cushion frame, and pre-connects the outer side to the car seat cushion frame with bolts and nuts. At the same time, the backrest frame is also pressed against the support frame 4. At this time, the two backrest frames are set up adjacent to each other.

[0027] Next, the angle adjustment motor 7 drives the two angle adjusters 5 to rotate synchronously through the linkage shaft 6, so that the support frame 4 can rotate relative to the fixed frame 3. Then, the support frame 4 can push the two backrest frames to rotate synchronously relative to the seat cushion frame to adjust the included angle of the two to the standard angle at the same time. Then, the bolts and nuts that are pre-connected to the two backrest frames and the seat cushion frame are tightened respectively, thereby completing the connection between the seat cushion frame and the two backrest frames, which can improve the assembly efficiency of the left backrest frame and the right backrest frame with the seat cushion frame.

[0028] Finally, cylinder 9 drives the swing arm 11 to move downward, and the other end of the swing arm 11 moves upward to disengage from the support leg and create clearance, so that the assembled car seat frame can be lifted off the workbench and removed.

[0029] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
