Furthermore, the inner baffle is a push-pull type or a downward turning type. The opening and closing are convenient, the waterproof performance is enhanced, and the automobile seat is more suitable for operating places of special vehicles.

Furthermore, a patterned aluminum plate is arranged on the inner wall of the box door. The anti-skid function of the stepping of the personnel is satisfied.

Furthermore, the connection mode between heavy hinge and connecting portion, the box lower part is the spiro union, and the equal pre-buried steel sheet of junction of connecting portion, box lower part. Ensuring the strength and reliability.

The beneficial effects of the utility model are as follows:

(1) The inner baffle plate of the utility model separates the box body into two spaces, the inward part forms a new space as a tool box, the outward part of the box door can be opened and pressed down to become a pedal, and the double functions of the tool box and the pedal are considered without mutual influence; heavy hinge and air spring cooperation are closed the chamber door under normal condition, and when the footboard state, heavy hinge is spacing on the one hand, and on the other hand provides the power of upwards bearing when pedal chamber door, and the air spring is used for pulling the chamber door, upwards pulling force when providing pedal chamber door. The safety and the stability of the step are ensured.

(2) The utility model discloses be used in new car, structure integration. When the special vehicle is used for overhauling and refitting the special vehicle, the outer shape of the special vehicle can be effectively connected and unified with the refitted vehicle. When some vehicles meet, the vehicle can be completed only by welding the reinforcing ribs of the box body, additionally arranging the inner baffle, the heavy hinge and the air spring and replacing a thicker box door, and the vehicle is simple in modification operation and controllable in cost; the overall structure is reliable in locking, double-layer waterproof, and meanwhile, the functions of providing tool storage space and stepping are considered.
