in the locked state, the first locking assembly locks the first and second slide rails; when the seat is in the unlocking state, the first locking component releases the first slide rail and the second slide rail, and the seat body drives the first slide rail to slide relative to the second slide rail under the action of external force.

5. The kinematic seat of claim 4, wherein the rotating assembly includes a fixed portion and a rotating portion, the fixed portion being disposed on the mounting base, the rotating portion being rotatably disposed on the fixed portion, the seat body and the sliding assembly both being connected to the rotating portion and rotating synchronously with the rotating portion;

in the locked state, the second locking member locks the rotating portion and the fixing portion; when the seat is in the unlocking state, the second locking assembly releases the rotating part and the fixing part, and the seat body drives the sliding assembly and the rotating part to rotate relative to the fixing part under the action of external force.

6. The kinematic seat of claim 5, wherein the first locking assembly includes a first driving portion and a latch arm, the latch arm being rotatably disposed with respect to the second slide rail, one of the latch arm and the first slide rail having a latch slot and the other having a latch protrusion;

when the locking mechanism is in the unlocking state, the clamping arm is in the unlocking position, and the clamping protrusion is separated from the clamping groove; when the locking mechanism is in the locking state, the clamping arm is in the locking position, and the clamping protrusion is sleeved in the clamping groove;

the first driving part is in transmission connection with the clamping arm and is used for driving the clamping arm to rotate until the clamping groove is separated from or sleeved on the clamping protrusion.

7. The kinematic seat of claim 6, wherein the first drive portion includes a first drive member and a first telescoping column, the first drive member being in driving connection with the first telescoping column;

the first driving piece is controlled by the air source to inflate and drive the first telescopic column to protrude towards one side close to the clamping arm so as to drive the clamping arm to rotate to separate the clamping groove from the clamping protrusion.

8. The kinematic seat of claim 7, wherein the locking mechanism further comprises a spring that elastically deforms when the snap-in arm is in the unlocked position, storing a spring force that enables the snap-in arm to switch from the unlocked position to the locked position;

when the first driving piece drives the first telescopic column to retract towards one side far away from the clamping arm, the clamping arm is switched to the locking position from the unlocking position under the action of the elastic force, and the clamping groove is arranged in a protruding sleeved mode with the clamp.

9. The kinematic seat of claim 5, wherein the second locking assembly comprises a second driving portion and a rotation stopping assembly, and the rotation portion has a plurality of locking holes along its circumference;

when the locking mechanism is in the unlocked state, at least part of the rotation stop assembly is inserted into the locking hole; when the locking mechanism is in the locking state, the rotation stopping assembly is disengaged from the locking hole;

the second driving part is in transmission connection with the rotation stopping assembly and is used for driving the rotation stopping assembly to reciprocate along the axis direction of the locking hole until the rotation stopping assembly is partially inserted into the locking hole or the rotation stopping assembly is separated from the locking hole.

10. The kinematic seat of claim 9, wherein the second driving portion includes a second driving member and a second retractable post, the second driving member is in transmission connection with the second retractable post, and a side of the second retractable post away from the second driving member is connected with the rotation stopping assembly;

when the second driving piece is inflated by the air source, the second driving piece drives the second telescopic column to protrude towards one side far away from the fixing part;

when the second driving piece is controlled to be pumped by the air source, the second driving piece drives the second telescopic column to retract towards one side close to the fixed part so as to drive the rotation stopping assembly to move in a reciprocating manner along the axis direction of the locking hole.

11. A commercial vehicle comprising a sports seat as claimed in any one of claims 1 to 10.
