[0008] Furthermore, a support block is provided on the sliding seat, and the support block is located below the connecting frame. A guide cylinder is provided in the middle of the support block, and the linkage shaft is vertically slidably connected in the guide cylinder.

[0009] Furthermore, the bracket is provided with a plurality of triangular hollow holes.

[0010] The beneficial effects of this scheme are as follows: (1) The seat is installed on the bracket. When the seat is in the locked state, the teeth at both ends of the locking plate connected to the sliding seat are inserted into the tooth grooves of the ground rail, thereby limiting the movement of the sliding seat and locking the seat. When the front and rear position of the seat needs to be adjusted, the driving member rotates the shaft, and the rotation of the shaft drives the connecting frame to rotate upward. The linkage shaft located in the strip hole of the connecting frame moves upward with the connecting frame, thereby driving the locking plate to move upward, and the teeth on the locking plate are disengaged from the tooth grooves. The sliding seat loses the locking restriction of the locking plate and can slide along the ground rail to adjust the front and rear position of the seat. After adjusting to the appropriate position, the driving member drives the shaft back, the linkage shaft and the locking plate move downward, and the teeth at both ends of the locking plate are inserted into the corresponding tooth grooves to complete the locking of the seat. This scheme has a simple structure and is easy to operate.

The locking assembly includes a driving member, a rotating shaft 4, a connecting frame 5, a linkage shaft 6 and a locking plate 7, the rotating shaft 4 is rotatably connected to the bracket 3, the connecting frame 5 is fixed on the rotating shaft 4, and the connecting frame 5 is provided with a strip groove, combined with Figure 2 , Figure 3 As shown, both ends of the locking plate 7 are provided with vertically downward latching teeth 8, the bottom of the ground rail 1 is provided with a plurality of tooth grooves 9, the linkage shaft 6 passes through the strip groove and is fixedly connected to the locking plate 7, a support block 10 is provided on the sliding seat 2, the support block 10 is located below the connecting frame 5, a guide cylinder 11 is provided in the middle of the support block 10, and the linkage shaft 6 is vertically slidably connected in the guide cylinder 11; the driving member includes an unlocking handle 12, a foot pedal 13, a fixing frame 14 and a tension spring 15, one end of the rotating shaft 4 passes through the bracket 3 and is fixed to the unlocking handle 12, the fixing frame 14 is fixed on the rotating shaft 4, one end of the foot pedal 13 is fixedly connected to the fixing frame 14, and the tension spring 15 is connected between the foot pedal 13 and the bracket 3.

[0019] The specific implementation process is as follows: the seat is installed on the bracket 3. When the seat is in the locked state, the teeth 8 at both ends of the locking plate 7 connected to the sliding seat 2 are inserted into the tooth grooves 9 of the ground rail 1, thereby limiting the movement of the sliding seat 2 and realizing locking of the seat. When the front and rear position of the seat needs to be adjusted, the driving member rotates the rotating shaft 4, and the rotation of the rotating shaft 4 drives the connecting frame 5 to rotate upward. The linkage shaft 6 located in the strip hole of the connecting frame 5 moves up with the connecting frame 5, thereby driving the locking plate 7 to move upward, and the teeth 8 on the locking plate 7 are disengaged from the tooth grooves 9. The sliding seat 2 loses the locking restriction of the locking plate 7 and can slide along the ground rail 1 to realize the adjustment of the front and rear position of the seat. After adjusting to the appropriate position, the driving member drives the rotating shaft 4 to return, the linkage shaft 6 and the locking plate 7 move downward, and the teeth 8 at both ends of the locking plate 7 are inserted into the corresponding tooth grooves 9 to complete the locking of the seat. This scheme has a simple structure and is easy to operate.

[0020] The driving member of this embodiment adopts a combination of an unlocking handle 12 and a foot pedal 13, which can meet the needs of different in-vehicle spaces and unlocking requirements to complete the unlocking of the seat. The unlocking handle 12 method can meet the needs of people adjusting the seat while sitting on the seat, or the space in the vehicle is small and it is inconvenient for the passengers to move to other places. The unlocking method of the foot pedal 13 allows people to unlock the seat and the ground rail 1 behind the seat and move the seat, which is convenient for moving the seat over a long distance.
