In order to achieve the above-mentioned object, the present invention provides a piston for a vehicle, comprising: a piston storage face portion 40; a front wire connection hole 42 provided at a central portion of the piston storage face portion 40; A piston shaft center stopper 410 integrally formed with the piston axial end surface stopper 410 and a piston shaft rear stopper 450 installed at a rear surface of the piston shaft center portion 440, The piston moving body 400 installed in the piston cylinder 50 is in close contact with the inner wall of the air cylinder 50 and the piston shaft center portion 440 is provided between the piston storage face stopper 410 and the piston shaft rear face stopper 450, A piston moving body 400 in which a central shaft cylinder 440 is installed so as to move forward and backward and a piston moving body front wheel shaft 402 installed in a front edge of the piston moving body 400, And a piston-shaft rear booth A spring insertion groove portion 460 provided on the rear surface of the piston shaft rear portion stopper 450 and a piston insertion hole portion 460 formed on the rear surface of the spring insertion groove portion 460. [ And a rear wire connecting through hole (47) provided at a central portion of the rear portion (46) of the piston shaft, and a sliding door semiautomatic door using the piston.

In the piston of the present invention, a piston moving body portion 400 having a central cylinder is installed so that the central portion 440 of the piston rod is installed at the center,

When the piston center 440 is moved back and the piston moving body 440 having a greater diameter than the piston center 440 is attached to the front face of the piston center 440 and the piston moving body 440 moves The front and rear portions of the air are blocked or separated around the piston 4 by the body front flap 402,

On the other hand, when the piston shaft center portion 440 advances and the piston moving body portion 400 reaches the piston shaft rear stopper 450, the air provided on the front surface of the piston 4 flows outside the rim of the piston power storage surface stopper 410 Passes through the space between the piston shaft center portion 440 and the piston moving body portion 400 and is moved to the rear portion of the piston 4 so that the lower portion of the wire guide roller support and guide guide 21-2 provided at the rear portion of FIG. The air is discharged to the air discharge port 21 - 20 installed in the air conditioner 20 and smoothly opens the door.

The hanger of the present invention is a frame hanging a door,

The air cylinder of the present invention is provided with an air control valve at an end thereof,

On the contrary, when the hand is released from the door (FIG. 8), the piston is moved backward (FIG. 10) by the compression force of the spring (FIG. 10), and the air existing in front of the piston flows into the air cylinder So that the air pressure inside and outside of the air cylinder is made the same, and the door is closed slowly and smoothly.

When the door is opened, the piston (Fig. 5) is advanced by the force of hand-pushing (Fig. 2). At this time, air in the front surface of the piston passes between the center of the piston shaft and the piston moving body part 400, And thus receives only the resistance of the spring without the resistance of air,

When the door is closed (Fig. 8), the piston is retracted by the force of the expansion spring being contracted (Fig. 10), the pressure in the air on the front surface of the piston of the air cylinder is lowered, And the pressure inside the air cylinder is equal to the pressure of the outside and the rear surface of the piston to smoothly close the door to adjust the closing speed.

Hangs the door, hanging the door, and locks the door in the door hanger Laura.

Hereinafter, the present invention will be described in detail with reference to the drawings.
