The adjusting cylinder 52 is threadedly connected to the screw rod 51. According to the installation requirements of the vehicle seat slide rail assembly of the vehicle, rotate the adjusting cylinder 52. The rotation of the adjusting cylinder 52 realizes the adjustment of the total length of the adjusting cylinder 52 and the screw rod 51. The adjusting cylinder 52 and the screw rod 51 both drive the corresponding mounting seat 4 to move laterally, realizing the adjustment of the distance between the two mounting seats 4. The upper ends of the mounting seats 4 slide laterally inside the connection bin 6 under the guiding action of the guiding rod 19. The lateral movement of the mounting seats 4 drives the laterally adjacent U-shaped seats 53 to move laterally. The two laterally adjacent U-shaped seats 53 move towards each other. The U-shaped seats 53 drive the corresponding first connecting rod 54 and second connecting rod 55 to move laterally away from the center of the working disk 1. At the same time, the ends of the first connecting rod 54 and the second connecting rod 55 close to the center of the working disk 1 rotate relative to each other under the action of the connecting shaft, providing assistance for the lateral distance adjustment of the mounting seat 4. When the mounting seat 4 reaches the required distance, stop rotating the adjusting cylinder 52, and then thread the locking bolts 21 into the threaded holes and the longitudinally adjacent locking holes 20 respectively, thereby realizing the locking of the relative positions of the mounting seat 4 and the working disk 1.

The input end of the motor 9 is electrically connected to the output end of the control switch group 22. When the motor 9 operates, the output shaft of the motor 9 rotates to drive the driving shaft 7 to rotate, thereby driving the driving gear to rotate. The driving gear rotates to drive the driven gear to rotate. The driven gear rotates to drive the steering shaft 8. The steering shaft 8 rotates to drive the steering seat 10 to rotate. The steering seat 10 rotates to drive the rotating seat 2 to rotate, thereby driving the sliding bins 3 to rotate. The rotation of the sliding bins 3 drives the support plate 17 to rotate through the sliding seat 12, and further drives the vehicle seat to rotate horizontally through the connecting seat 18, thereby realizing the angle adjustment of the vehicle seat;

[0025] Among them: Slide rods 11 are fixedly connected inside the sliding bins 3. Sliding seats 12 are slidably connected to the middle of the slide rods 11. The upper ends of the sliding seats 12 are fixedly connected to the lower ends of the support plates 17. Connecting seats 18 are fixedly connected to the left and right ends of the upper surface of the support plates 17. Uniformly distributed mounting holes are provided at the upper ends of the connecting seats 18. Symmetrically distributed supports are fixedly connected to the lower ends of the support plates 17. Rotating shafts 15 are rotatably connected to the lower ends of the supports. Moving wheels 14 are fixedly connected to the opposite ends of the rotating shafts 15. Guide rails 13 are fixedly connected to the upper ends of the sliding bins 3. The moving wheels 14 are slidably connected to the vertically adjacent guide rails 13. A bidirectional motor 16 is provided at the lower end of the support plate 17. The output shafts of the bidirectional motor 16 are fixedly connected to the ends of the horizontally adjacent rotating shafts 15 close to the center of the support plate 17. The input end of the bidirectional motor 16 is electrically connected to the output end of the control switch group 22. When the bidirectional motor 16 operates, the output shafts of the bidirectional motor 16 rotate to drive the horizontally adjacent rotating shafts 15 to rotate. The rotating shafts 15 rotate to drive the horizontally adjacent moving wheels 14 to rotate. The moving wheels 14 all roll longitudinally under the action of the vertically adjacent guide rails 13. Thereby, the support plate 17 longitudinally slides between the sliding bins 3 with the assistance of the sliding seat 12. The slide rods 11 provide guiding functions for the movement of the vertically adjacent sliding seats 12, and finally realize the longitudinal movement of the vehicle seat.

[0026] The working principle of a vehicle seat slide rail assembly provided by the utility model is as follows: During operation, according to the installation requirements of the vehicle seat slide rail assembly of the vehicle, the adjusting cylinder 52 is rotated. The rotation of the adjusting cylinder 52 realizes the adjustment of the total length of the adjusting cylinder 52 and the screw rod 51. Both the adjusting cylinder 52 and the screw rod 51 drive the corresponding mounting seats 4 to move horizontally, realizing the adjustment of the distance between the two mounting seats 4. The upper ends of the mounting seats 4 slide horizontally inside the connecting bin 6 under the guiding action of the guiding rod 19. The horizontal movement of the mounting seats 4 drives the horizontally adjacent U-shaped seats 53 to move horizontally. The two horizontally adjacent U-shaped seats 53 move towards each other. The U-shaped seats 53 drive the corresponding connecting rod one 54 and connecting rod two 55 to move horizontally in the direction away from the center of the working disk 1. At the same time, the ends of the connecting rod one 54 and the connecting rod two 55 close to the center of the working disk 1 rotate relative to each other under the action of the connecting shaft, providing assistance for the horizontal distance adjustment of the mounting seat 4. When the mounting seat 4 reaches the required distance, the rotation of the adjusting cylinder 52 is stopped. Then, the locking bolts 21 are threaded into the threaded holes and the longitudinally adjacent locking holes 20 respectively, thereby realizing the locking of the relative positions of the mounting seat 4 and the working disk 1. Then, the mounting holes inside the mounting seat 4 are stably connected to the threaded holes one inside the vehicle through bolts, thereby realizing the stable connection between the vehicle seat slide rail assembly and the vehicle. Then, the vehicle seat is connected to the upper end of the connecting seat 18 through the connecting bolts, realizing the installation of the vehicle seat. Then, the operator controls the two-way motor 16 to operate through the control switch group 22. The rotation of the output shaft of the two-way motor 16 drives the horizontally adjacent rotating shafts 15 to rotate. The rotation of the rotating shafts 15 drives the horizontally adjacent moving wheels 14 to rotate. The moving wheels 14 roll longitudinally under the action of the vertically adjacent guide rails 13. Thus, the support plate 17 slides longitudinally between the sliding bins 3 with the assistance of the sliding seat 12. The sliding rods 11 provide guiding effects for the movement of the vertically adjacent sliding seats 12. Finally, the longitudinal movement of the vehicle seat is realized. When the vehicle seat moves to the required position, the operator closes the two-way motor 16 through the control switch group 22 and operates the motor 9. The rotation of the output shaft of the motor 9 drives the driving shaft 7 to rotate, thereby driving the driving gear to rotate. The rotation of the driving gear drives the driven gear to rotate. The rotation of the driven gear drives the steering shaft 8. The rotation of the steering shaft 8 drives the steering seat 10 to rotate. The rotation of the steering seat 10 drives the rotating seat 2 to rotate, thereby driving the sliding bin 3 to rotate. The rotation of the sliding bin 3 drives the support plate 17 to rotate through the sliding seat 12, and then drives the vehicle seat to rotate horizontally through the connecting seat 18, thereby realizing the angle adjustment of the vehicle seat. When the vehicle seat rotates to the required angle, the operator closes the motor 9 through the control switch group 22.

[0027] It should be noted that in the above embodiments, the motor 9 disclosed can be an LS28A18 motor, the two-way motor 16 can be a 28HS3306B4K-01 stepping motor, and the control switch group 22 is provided with control buttons that correspond to the motor 9 and the two-way motor 16 one by one and control their switches.

[0028] The above are only embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall similarly be included within the patent protection scope of the present utility model.
