Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-3 , this embodiment provides a technical solution: a slide rail assembly for an automobile seat, including a base 1 and a steering drive mechanism 4;

[0023] Base 1: A steering track 2 is fixedly connected to its upper end. The upper end of the steering track 2 is rotatably connected to a turntable 3. Two sliding bins 5 are connected to the upper end of the turntable 3 through evenly distributed screws 13. Sliding seats 6 are slidably connected inside the sliding bins 5. The upper ends of the sliding seats 6 are fixedly connected to the lower ends of the drive bins 7. Guide rods 11 are fixedly connected inside the sliding bins 5. The middle parts of the guide rods 11 are slidably connected to the lower ends of the vertically adjacent sliding seats 6. Protective covers 16 are snap-connected to the rear ends of the sliding bins 5. Installation holes are evenly distributed inside the base 1. Connecting seats 12 are fixedly connected to the left and right ends of the upper surface of the drive bin 7. Symmetrically distributed connection holes are provided at the upper ends of the connecting seats 12;

[0024] Steering drive mechanism 4: It is arranged between the base 1 and the turntable 3. The steering drive mechanism 4 includes a motor 41, a drive gear 42 and an internal gear ring 43. The internal gear ring 43 is fixedly connected to the inner wall of the turntable 3. The motor 41 is arranged in the middle of the base 1. The upper end of the output shaft of the motor 41 is fixedly connected to the lower end of the drive gear 42. The drive gear 42 is meshed with the internal gear ring 43. The input end of the motor 41 is electrically connected to the output end of the control switch group 15. When the motor 41 operates, the output shaft of the motor 41 rotates to drive the drive gear 42 to rotate. The drive gear 42 rotates to drive the internal gear ring 43 to rotate. The internal gear ring 43 rotates to drive the turntable 3. The turntable 3 rotates on the upper end of the steering track 2. The turntable 3 rotates to drive the sliding bin 5 to rotate, and then drives the automobile seat to rotate horizontally through the connecting seat 12, so as to realize the angle adjustment of the automobile seat;

[0025] Among them: It also includes a control switch group 15. The control switch group 15 is located on the front side of the base 1. The input end of the control switch group 15 is electrically connected to an external power source;

[0026] Wherein: Symmetrically distributed supports are fixedly connected to both the left and right ends of the bottom wall of the driving bin 7. Two adjacent supports in the transverse direction are rotatably connected to the same rotating shaft 8. Driving wheels 9 are fixedly connected to the outer surfaces of the rotating shaft 8 facing away from each other. Slide rails 10 are fixedly connected to one end of the upper surface of the driving bin 7 close to the center of the base 1. The driving wheels 9 are slidably connected to the vertically adjacent slide rails 10. A bidirectional motor 14 is arranged in the middle of the driving bin 7. The output shafts of the bidirectional motor 14 are fixedly connected to one end of the adjacent rotating shafts 8 close to the center of the base 1. The input end of the bidirectional motor 14 is electrically connected to the output end of the control switch group 15. When the bidirectional motor 14 operates, the output shafts of the bidirectional motor 14 rotate to drive the adjacent rotating shafts 8 in the transverse direction to rotate. The rotation of the rotating shafts 8 drives the adjacent driving wheels 9 in the transverse direction to rotate. The driving wheels 9 all roll longitudinally under the action of the vertically adjacent slide rails 10. Thus, the driving bin 7 longitudinally slides between the sliding bins 5 with the assistance of the sliding seats 6. The guide rods 11 provide guiding functions for the movement of the vertically adjacent sliding seats 6, and finally realize the longitudinal movement of the vehicle seat.

[0027] The working principle of a slide rail assembly for a vehicle seat provided by the present utility model is as follows: During operation, the user stably connects the mounting holes inside the base 1 to the threaded holes in the working area through bolts, thereby realizing the stable installation of the base 1, the turntable 3, and other mechanisms. Then, the user stably connects the connection holes at the upper end of the connection seat 12 to the fixing holes at the lower end of the vehicle seat through connection bolts, thereby realizing the stable installation of the vehicle seat. After the installation is stable, the user operates the bidirectional motor 14 through the control switch group 15. The output shafts of the bidirectional motor 14 rotate to drive the adjacent rotating shafts 8 in the transverse direction to rotate. The rotation of the rotating shafts 8 drives the adjacent driving wheels 9 in the transverse direction to rotate. The driving wheels 9 all roll longitudinally under the action of the vertically adjacent slide rails 10. Thus, the driving bin 7 longitudinally slides between the sliding bins 5 with the assistance of the sliding seats 6. The guide rods 11 provide guiding functions for the movement of the vertically adjacent sliding seats 6, and finally realize the longitudinal movement of the vehicle seat. When the vehicle seat moves to the required position, the user turns off the bidirectional motor 14 through the control switch group 15. Then, the user operates the motor 41 through the control switch group 15. The output shaft of the motor 41 rotates to drive the driving gear 42 to rotate. The rotation of the driving gear 42 drives the internal gear ring 43 to rotate. The rotation of the internal gear ring 43 drives the turntable 3. The turntable 3 rotates on the upper end of the steering rail 2. The rotation of the turntable 3 drives the sliding bin 5 to rotate, and then drives the vehicle seat to rotate horizontally through the connection seat 12, so as to realize the angle adjustment of the vehicle seat. When the vehicle seat rotates to the required angle, the user turns off the motor 41 through the control switch group 15.

[0028] It should be noted that the motor 41 disclosed in the above embodiments may be an LS28A18 motor, the bidirectional motor 14 may be a 28HS3306B4K-01 stepper motor, and the control switch group 15 is provided with control buttons corresponding to the motor 41 and the bidirectional motor 14 one by one to control their switches.

[0029] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be similarly included in the patent protection scope of the present invention.
