The bottom end of the mounting plate 4 is fixedly mounted on the vehicle floor, the upper end of the mounting plate 4 is fixedly connected to the telescopic mechanism, one end of the telescopic mechanism is fixedly connected to the lifting mechanism, and the lifting mechanism for driving the push rod 3 to move up and down is fixedly connected to the telescopic mechanism.

[0035] The lifting mechanism includes a dual-axis motor 5, a slide 6, and two movable parts. Two guide plates 7 are fixedly connected to both sides of one end of the mounting plate 4. The two sides of the bottom of the slide 6 are slidably arranged on the two guide plates 7. The telescopic mechanism is fixedly connected to one side of the slide 6. The two movable parts are respectively arranged on both sides of the slide 6. The dual-axis motor 5 for driving the two movable parts to move is fixedly connected to the slide 6.

[0036] The movable parts include a connecting rod 29, a disc 9, a connecting rod 8, a sliding shaft 14, a movable plate 15 and a slide rail 16. One end of the connecting rod 8 is fixedly connected to the output end of the dual-axis motor 5, the other end of the connecting rod 8 is fixedly connected to the center of one side of the disc 9, and a movable shaft 10 is fixedly connected to the edge of the other side of the disc 9.

At this time, the fixed guide rail 1 does not lock the movable guide rail 2. At this time, the telescopic mechanism is started to drive the lifting mechanism and the push rod 3 to adjust the front and rear positions. After the adjustment is completed, the dual-axis motor 5 rotates half a circle again to drive the connecting rod 29 to reset. At this time, the push rod 3 is reset, and the fixed guide rail 1 locks the movable guide rail 2 again, completing the limit of the movable guide rail 2;

They are embedded in the inner wall of the fixed guide rail 1 and in contact with the outer wall of the movable guide rail 2 to reduce the friction of the movable guide rail 2 during the sliding process, ensuring that the seat can slide back and forth smoothly and easily.

[0040] A locking rod 22 is provided for sliding inside the fixed guide rail 1, one end of the locking rod 22 is fixedly connected to one end of the push rod 3, the upper end of the middle portion of the locking rod 22 is rotatably provided on the inner wall of the movable guide rail 2, and an elastic element 23 is clamped on the upper end of the movable guide rail 2, and the other end of the elastic element 23 is clamped on one side of the locking rod 22, and the elastic element 23 is used to apply a pulling force to the locking rod 22 to make it in a horizontal state, and two locking tooth plates 24 are relatively provided at the other end of the locking rod 22, and a plurality of locking tooth grooves 25 are provided on the locking tooth plate 24, and a plurality of hook-shaped teeth 26 provided on the bottom side of the movable guide rail 2 are respectively clamped in the plurality of locking tooth grooves 25, and the plurality of locking tooth grooves are movably clamped with positioning teeth 20 provided on the inner side of the fixed guide rail 1;

[0041] It should be noted that when the push rod 3 is subjected to an upward thrust, the locking rod 22 will drive the locking tooth plate 24 to deflect downward, so that the locking tooth groove on the locking plate disengages from the positioning tooth 20 on the fixed guide rail 1. At this time, the telescopic mechanism starts to drive the lifting mechanism and the push rod 3 to adjust the front and rear positions. After the adjustment is completed, the lifting mechanism drives the push rod 3 to descend, and the push rod 3 drives the locking rod 22 to reset, so that the locking tooth groove on the locking plate is stuck in the positioning tooth 20 on the fixed guide rail 1, completing the limit of the movable guide rail 2.

[0042] Two stoppers 27 are provided on both sides of the interior of the fixed guide rail 1 , and two limit blocks 28 are provided on both sides of the bottom of the movable guide rail 2 to ensure that the movable guide rail 2 slides inside the fixed guide rail 1 .
