[0025] The specific implementation process is as follows: when the seat is in a locked state, the latching teeth at both ends of the locking plate are inserted into the tooth grooves of the floor 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 rotating shaft is rotated by the driving member, and the rotation of the rotating 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 up, and the latching 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 floor rail to adjust the front and rear position of the seat. After adjusting to the appropriate position, the driving member drives the rotating shaft back, the linkage shaft and the locking plate move downward, and the latching 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.

[0026] The driving component adopts a combination of an unlocking handle and a foot pedal, which can meet the needs of different in-vehicle spaces and unlocking requirements to complete the unlocking of the seat. The unlocking handle method can meet the needs of people adjusting the seat while sitting on the seat, or adjust the seat when the space in the car is small and it is inconvenient for the passengers to move to other places; the foot pedal unlocking method allows people to unlock the seat and the floor rail behind the seat and move the seat, which is convenient for moving the seat over a longer distance.

[0027] The energy-absorbing component can absorb the impact when the vehicle is subjected to an explosion or severe bumps reaching a certain value, thereby ensuring the relative stability of the seat.

[0028] The rotating mechanism can rotate the seat direction according to riding requirements, and the seat back can be adjusted according to the needs and comfort of the passengers.
