[0002] Car seats can be categorized by shape into split seats and bench seats; by function into fixed, removable, and adjustable seats; and by the number of passengers into single, double, and multi-person seats. Based on performance, they have evolved from the earliest fixed seats to multi-functional power-adjustable seats, including air-cushioned seats, electric seats, stereo seats, recovery seats, and even electronically adjustable seats. They can also be categorized by material into leather seats and cloth seats, as well as seats for special purposes such as child seats and racing seats. The main body of the car seat backrest frame is an indispensable component, and it needs to be fixed during the manufacturing process.

[0003] In the existing technology, the main body of the car seat back frame needs to be fixed during processing. However, the current fixing mechanism can usually only fix the car seat back, which is inconvenient when the angle of the seat back needs to be adjusted, and affects the processing efficiency of the main body of the back frame. Therefore, a fixing mechanism for the car seat back frame is needed. Utility Model Content

Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figures 1-4 As shown, the present invention provides a car seat back frame fixing mechanism, including a mounting plate 1, and a quick fixing mechanism 2 is provided on the rear side of the mounting plate 1.

[0024] The quick-fixing mechanism 2 includes a bidirectional screw 9. During rotation, the bidirectional screw 9 can drive the threaded blocks 8 to move closer or further apart. Threaded blocks 8 are threadedly connected to both sides of the outer periphery of the bidirectional screw 9. The threaded blocks 8 are fixedly connected to the middle of the front wall of the U-shaped rod 7. During the movement of the threaded blocks 8, the U-shaped rod 7 and the slider 4 move synchronously. The upper and lower parts of the front end of the U-shaped rod 7 are fixedly connected to the slider 4. The front wall of the slider 4 is fixedly connected to the L-shaped plate 5. The inner side wall of the L-shaped plate 5 is fixedly connected to the pressure-applying inclined block 12. The pressure-applying inclined block 12 can apply a pushing force to the backrest frame body 13 to move towards the side of the mounting plate 1, which facilitates better fixation of the backrest frame body 13. The sliders 4 are respectively passed through and slidably connected to the left and right sides of the outer periphery of the limiting rod 6. The backrest frame body 13 is provided on the front side of the front wall of the mounting plate 1.

[0025] The left and right L-shaped plates 5 are symmetrically arranged about the middle of the mounting plate 1. The limiting rods 6 are fixedly connected to the middle of the inner side of the mounting groove 3. The mounting groove 3 is respectively set on the upper and lower sides inside the mounting plate 1. The middle of the left and right walls of the mounting plate 1 is fixedly connected to the rotating shaft 14. The rotating shaft 14 is set so that the mounting plate 1 can rotate and adjust the processing angle of the front backrest frame body 13 of the mounting plate 1.

[0026] The rotating shaft 14 passes through and is rotatably connected to the middle of the support rod 15. A rotary cylinder 16 is fixedly connected to the middle of the right side wall of the right support rod 15. The output end of the rotary cylinder 16 is fixedly connected to the right rotating shaft 14. The support rod 15 is fixedly connected to the left and right ends of the middle of the top wall of the base plate 18. Reinforcing rods 17 are fixedly connected to the bottom of the front and rear walls of the support rod 15. The other end of the reinforcing rod 17 is fixedly connected to the left and right ends and the front and rear parts of the top wall of the base plate 18. The reinforcing rod 17 can improve the connection strength between the support rod 15 and the base plate 18.

[0027] The bidirectional screw 9 is rotatably connected between two sets of fixed plates 10. The fixed plates 10 are respectively fixedly connected to the left and right ends of the middle of the rear wall of the mounting plate 1. The right wall of the right mounting plate 1 is fixedly connected to the drive motor 11. The output end of the drive motor 11 is fixedly connected to the bidirectional screw 9. The drive motor 11 is the power component for the rotation of the bidirectional screw 9.

[0028] Working principle: When the main body 13 of the car seat backrest frame needs to be processed, it is placed in front of the mounting plate 1 and the drive motor 11 is started. The output shaft of the drive motor 11 rotates, causing the bidirectional screw 9 to rotate. During the rotation of the bidirectional screw 9, the threaded blocks 8 on both sides move away from each other. During the movement of the threaded blocks 8, the U-shaped rod 7 and the slider 4 move. During the movement of the slider 4, the L-shaped plate 5 moves. With the cooperation of the two sets of L-shaped plates 5 and the pressure inclined block 12, the main body 13 of the backrest frame is fixed. When processing the main body 13 of the backrest frame, the rotary cylinder 16 is started. The output end of the rotary cylinder 16 rotates, causing the rotating shaft 14 to rotate. During the rotation of the rotating shaft 14, the mounting plate 1 rotates, and the angle of the mounting plate 1 is adjusted to facilitate the processing of the main body 13 of the car seat backrest frame and improve the processing efficiency of the main body 13 of the backrest frame.
