The left slide rail 3 and the right slide rail 4 are slidably connected inside the left slideway and the right slideway. The surfaces of the left slide rail 3 and the right slide rail 4 are respectively provided with a left slide rail unlocking component 5 and a right slide rail unlocking component 6 to unlock the locking of the left slide rail 3 and the right slide rail 4. The structures of the left slide rail unlocking component 5 and the right slide rail unlocking component 6 are the same; through the above components, it is convenient for the rotation and movement of the seat.

[0025] The left slide rail unlocking assembly 5 includes a bracket 9. The bracket 9 is connected to the left slide rail 3 to fix the position of the left slide rail unlocking assembly 5. An unlocking piece rotating shaft 14 is fixedly connected inside the bracket 9 to drive the unlocking piece 10 to rotate. An unlocking piece return spring 17 is arranged on the side surface of the unlocking piece rotating shaft 14 to reset the unlocking piece 10. One end of the unlocking piece return spring 17 is fixedly connected to the inner surface of the chute to provide the power for resetting. The unlocking piece 10 is rotatably connected to the side surface of the unlocking piece rotating shaft 14 to release the locking between the left slide rail 3 and the left slideway. The unlocking piece 10 is engaged with the bayonet position inside the left slideway, so as to limit the position of the left slide rail 3 and fix the position of the left slide rail 3. A rivet 15 is fixedly connected to the side surface of the unlocking piece 10, and the side surface of the rivet 15 is fixedly connected to the side surface of the unlocking piece return spring 17 to provide the elastic force source of the unlocking piece return spring 17. A plastic sleeve 16 is fixedly connected to one end of the unlocking piece 10. A cam rotating shaft 13 is fixedly connected inside the bracket 9. A cam return spring 11 is arranged on the side surface of the cam rotating shaft 13 to reset the cam 12. One end of the cam return spring 11 is fixedly connected to the cam 12. The cam 12 is rotatably connected to the side surface of the cam rotating shaft 13. When the cam 12 rotates around the cam rotating shaft 13, it drives the rivet 15 to rotate. A chute is arranged inside the cam 12, and the unlocking piece rotating shaft 14 is located inside the chute to facilitate the movement between the cam 12 and the unlocking piece rotating shaft 14.

[0026] One end of the cable 2 away from the cam 12 is connected with an unlocking handle 1 for convenient manual operation. The unlocking handle 1 is connected to the seat cushion structure to fix the position of the unlocking handle 1;

[0027] A turntable unlocking lever 8 is arranged on the upper surface of the turntable 7 to unlock the rotation function of the turntable 7. The lower surface of the turntable 7 is rotatably connected with a chassis to be connected to the vehicle and fix the position of the seat. A locking structure is arranged between the chassis and the turntable 7. The turntable unlocking lever 8 is connected to the locking structure below the turntable 7, and the locking mechanism is the same as that of the existing vehicle seat.

[0028] Working principle: Locked state: The cam 10 is in the uppermost position under the action of the left cam return spring 11, and the unlocking piece 10, the rivet 15 and the plastic sleeve 16 are in the uppermost position under the action of the left unlocking piece return spring 17. At this time, the left slide rail 3, the right slide rail 4 and the turntable 7 are all in the locked state. The seat cannot slide forward and backward or rotate;

[0029] Slide rail unlocking state: The unlocking handle 1 is adjusted upward by a small angle, driving the cable 2 to pull the cam 12 to rotate around the cam rotating shaft 13. The cam 12 drives the rivet 15, the unlocking piece 10 and the plastic sleeve 16 to rotate downward around the unlocking piece rotating shaft 14 to unlock the slide rail. The slide rail can slide forward. At this time, the lower end contour of the cam 12 is located above the turntable unlocking lever 8 without interference, and the slide rail can slide forward for a longer stroke;

[0030] Linkage unlocking state: The unlocking handle 1 is adjusted upward by a large angle, driving the cable 2 to pull the cam 12 to rotate around the cam rotating shaft 13. The cam 12 drives the rivet 15, the unlocking piece 10 and the plastic sleeve 16 to rotate downward around the unlocking piece rotating shaft 14 to unlock the slide rail. After the slide rail is unlocked, the cam 12 can still rotate forward by a larger angle. At this time, the rivet 15, the unlocking piece 10 and the plastic sleeve 16 remain stationary. The slide rail slides forward, and the lower contour of the cam 12 contacts the turntable unlocking lever 8 and drives it to rotate forward to unlock the turntable 7. At this time, the seat can realize the rotation function.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
