[0019] Please see Figures 1-4In this embodiment of the utility model, the automotive seat back rotation force testing fixture includes a base 1. An L-shaped fixing frame 2 is connected to the upper surface of the base 1. A cylinder 3 is installed on the inner top wall of the L-shaped fixing frame 2. A piston rod 4 is connected to the output end of the cylinder 3. A clamping block 5 is connected to the bottom end of the piston rod 4. A fixing plate 6 is connected to the upper surface of the base 1. A first pin seat 7 is connected to the front of the fixing plate 6. An electric push rod 8 is installed on the front of the first pin seat 7. A second pin seat 9 is connected to the output end of the electric push rod 8. A backrest splicing plate 10 is connected to the front of the second pin seat 9. The backrest splicing panel 10 has two threaded holes 11 inside, and two fastening screws 12 are placed on the back of each backrest splicing panel 10. A torque sensor 13 is installed on the front of the fixing plate 6, and a data storage module 14 is installed on the upper surface of the L-shaped fixing bracket 2. A touch screen 15 is installed on the front of the data storage module 14. The torque sensor 13 can detect the rotational force of the seat back in real time, which can avoid the subjective error of manual detection. At the same time, the data storage module 14 can completely store the test data, which is convenient for subsequent review and analysis of the test results, and the data traceability is strong.

[0020] The left and right sides of the fixed plate 6 are connected to reinforcing seats 16. The bottom surfaces of the two reinforcing seats 16 are connected to the upper surface of the base 1. The upper surface of the base 1 is connected to a protective pad 17. The outer surface of the protective pad 17 is provided with anti-slip texture. The bottom surface of the clamping block 5 is connected to a buffer pad 18. The buffer pad 18 is made of rubber. The reinforcing seats 16 on both sides of the fixed plate 6 enhance the connection rigidity between the fixed plate 6 and the base 1, preventing the fixed plate 6 from tilting when the electric push rod 8 applies force. This provides a stable benchmark for rotational force detection and reduces test errors caused by structural shaking. The protective pad 17 on the base 1 not only plays an anti-slip role but also buffers the impact force of the seat contacting the base 1, further protecting the appearance and structural integrity of the workpiece. The rubber buffer pad 18 on the bottom surface of the clamping block 5 can prevent hard contact damage to the seat surface when the cylinder 3 clamps, reducing the scrap rate of the workpiece after testing.

[0021] A control box 19 is installed on the left side of the L-shaped mounting bracket 2. A set of control buttons 20 is installed on the left side of the control box 19. Two operation indicator lights 21 are installed on the left side of the control box 19. Positioning plates 22 are connected to both sides of the base 1. A set of positioning holes 23 are opened inside the two positioning plates 22. The operation indicator lights 21 can intuitively reflect the operating status of the tooling, avoid operator misoperation, and improve operation safety. By using the cooperation of the positioning plates 22 and the positioning holes 23, the base 1 can be accurately positioned, so that the base 1 can be quickly fixed to the test table and the tooling can be prevented from shifting.

[0022] The working principle of this utility model is as follows: When using this device, firstly, the car seat back to be tested is placed on the protective pad 17 on the upper surface of the base 1. Then, through the two threaded holes 11 inside the backrest splicing plate 10, the seat back is rigidly connected to the backrest splicing plate 10 with the fastening screw 12. Then, the cylinder 3 on the inner top wall of the L-shaped fixing frame 2 is activated. The cylinder 3 pushes the piston rod 4 downward to extend, causing the clamping block 5 to approach the seat back until the buffer pad 18 on the bottom surface of the clamping block 5 is in close contact with the seat surface, thus completing the vertical fixation of the seat back and preventing the workpiece from moving during rotation testing. Next, the test parameters are set through the control button 20 on the control box 19 on the left side of the L-shaped fixing frame 2. After pressing the start button, the first pin seat 7 on the front of the fixing plate 6 is connected to the… The connected electric push rod 8 begins its telescopic movement; the output end of the electric push rod 8 drives the backrest splicing plate 10 and the fixed seat back to rotate around the rotation axis through the second pin seat 9, realizing the core action of applying rotational force. During the process of the electric push rod 8 driving the seat back to rotate, the torque sensor 13 installed on the front of the fixed plate 6 detects the reaction force generated when the seat back rotates in real time, and converts the detected force signal into an electrical signal and transmits it to the data storage module 14 on the upper surface of the L-shaped fixed frame 2. The data storage module 14 stores the real-time data and simultaneously transmits the data to the front touch screen 15, which intuitively displays the dynamic change curve and value of the rotational force, making it convenient for operators to monitor the test process in real time. The above is the complete operation process of this device.
