When operated in the position P1, a signal is sent to the solenoid valve 23 of the door 5 to be opened while the compressed air generated by the operation of the compressor 1 is stored in the air tank 2. It becomes.

When the open signal is sent to the solenoid valve 23 corresponding to the door 5 to be opened as described above, the air is supplied through the air hose 22 while the port position of the solenoid valve 23 is switched to the open position. The air is supplied to the door lock cylinder 10 and the door lock cylinder 16 at the same time through the air suction nipple 29 installed in the door 5 to be opened.

As described above, the rods 17 and 13 of the door lock cylinder 10 and the door lock cylinder 16 are operated by the pressure of the air supplied through the solenoid valve 23 to open the door 5. When the rod 17 of the door lock cylinder 16 operates first and pulls the actuator 42 installed in the door lock 18, the auxiliary lock 18b is operated upward to release the lock state of the door lock 18. The rod 13 of the door lock cylinder 10 is pulled out to open the door 5 in a hinged manner, and the time for the door lock cylinder 10 to operate after the door lock cylinder 16 operates is about 1 second. Because it operates with a short time difference of, it can be seen that it works almost together.

Referring to FIGS. 3 and 4, the operational relationship between the door lock cylinder 16 and the door lock cylinder 10 will be described in detail as follows.

When the door 5 is to be opened while the door 5 is closed, the solenoid valve 23 opens to open the door lock cylinder 16 when the switch 3a of the switch operation unit 3 is in the open position P1. Air is supplied to the rod to pull the rod 17 of the door lock cylinder 16, the front end of the rod 17, the pull rod 20 connecting the door lock 18 and the inner handle 19 is connected to the rod Since the pull rod 20 is pulled from the actuator 42 included in the door lock 18 since the state is connected by the 21, the auxiliary lock 18b is operated upward to open the door lock 18, thereby opening the door lock 18. ) Is locked to the door lock striker 26 is hanging.

In this state, the solenoid valve 23 is opened after a short time of about 1 second. Air is supplied to the door cylinder 10 through the air suction nipple 29, and the rod 13 of the door cylinder 10 is withdrawn. It pushes the door 5, the rod 13 of the door cylinder 10 is hingedly connected to the door hinge 15 installed on the door frame 4, the door cylinder ( The cylinder barrel 11 of 10) is hingedly installed by a hinge pin 12a on a hinge bracket 9 fixed to an inner surface of the inner panel 6 of the door 5 as shown in FIGS. 4 and 5. As the door hinge 15 and the rod 13 are installed on the outside of the cylinder barrel 11 and the hinge bracket 9 rather than the hinge portion 12 hinged, the door 5 is moved outward. Will be opened.

At this time, the cylinder barrel 11 is hingedly coupled to the hinge bracket 9 when the door 5 is opened to the outside, and the hinge part hinges according to the opening angle of the door when the door is rotatably opened. Will open smoothly.

In the case of manually opening and closing the door of a passenger car equipped with the present invention, when the switch 3a of the switch control unit 3 is selected as the neutral position N, the door lock cylinder 16 and the door lock cylinder 16 are respectively provided. Since compressed air has not been introduced, it is possible to open and close the door manually in the same way as opening and closing the door of a general passenger car.

In the present invention, as shown in Figure 2a is provided with a check valve 33 for allowing only air into the air tank at the inlet of the air tank supplied air from the compressor (1), each door (5) A check valve 33a for supplying air to each door 5 is provided at the outlet of the air tank 2 for supplying air, so that the engine is stopped and the air tank 2 is stopped even when the vehicle is stopped. The air filled in the air is not discharged to the compressor 1 side by the check valve 33 on the inlet side, and air is discharged from the air hose 22 connected between the door 5 and the air tank 2. Even when leakage occurs, the check valve 33a provided at the outlet side of the air tank 2 allows air to be supplied only to each door 5 side, so that the door 5 can be opened while the vehicle is stopped. will be.

On the other hand, when the door 5 is open and the door 5 is to be closed, the solenoid valve 23 is cut off when the switch 3a of the switch operating part 3 is operated to the neutral position N. Since the solenoid valve 23 is not opened, supply of air to the door lock cylinder 16 and the door lock cylinder 10 is blocked, so that the door 5 is manually closed.

In addition, when the switch 3a of the switch operating section 3 is operated to the closed position P2, a signal is supplied to the solenoid valve 23, the solenoid valve 23 is opened, and air acts on the opposite side to the door 첵 cylinder 10. Air is formed in the solenoid valve 23 through the installed air discharge nipple 28 and is discharged to the outside through the discharge port, and the rod 13 of the door cylinder 10 is caused by a sudden pressure decrease in the door cylinder 10. ) Is sucked into the cylinder barrel 10, so that the door 5 which is fastened to the door hinge 15 is closed.

Next, referring to FIGS. 6A and 6B, the driver automatically opens the driver's seat door 5 using the remote controller 40 as follows.

The door 5 can be opened or closed. In this state, the driver opens the switch control unit 3a so that the driver's door 5 can be opened from the outside using the normal remote control device 40. When the operation is performed at (P1), and then the door 5 is locked after getting off, each other door 5 is locked at the same time.

As described above, each door 5 is locked, that is, the auxiliary lock 18b connected to the actuator 42 as shown in (a) of FIG. 6A is hung on the main lock 18a. As shown in (b) of FIG. 6a, when the door open button, which is a wireless transmitter installed in the general remote control device 40, is operated, the door open signal is wirelessly transmitted by the internal circuit device of the passenger car. The door open signal transmitted wirelessly is received by the wireless receiver installed in the passenger car to drive the actuator 42 installed in the door lock 18.

Due to the driving of the actuator 42, the auxiliary lock 18b held by the main lock 18a is raised to release the lock state, and at this time, the limit switch when the auxiliary lock 18b is lifted from the main lock 18a. By pressing the contact 44 of 43, it becomes an energized state of an on state.

Therefore, as shown in FIG. 6B, when the limit switch 43 is in an energized state (on), a current of 12 V is supplied to the timer 45 to start counting the time. Until the completion is completed, the relay 46 is driven in an on state to maintain the relay switch 46a in an on-contact state to supply power of 12V to the solenoid valve 23.

When power is supplied to the solenoid valve 23, the switch operating part 3a is operated so as to be already in the open position P1, so that air is supplied to the door lock cylinder 10 and the door lock cylinder 16 installed inside the driver's door 5. By supplying the rods 13 and 17 are operated to open the door 5.

On the other hand, when the time counted by the timer 45 (for example, 6 seconds) elapses, the timer 45 stops the operation of the relay 46, so that the relay switch 46a is connected to the off contact solenoid valve. By shutting off the driving power of 23, the air supply to the door cylinder 10 is stopped, and the door 5 can be closed by hand.

That is, the time it takes for the driver to sit in the correct position from the time when the door 5 is opened is about 6 seconds, and after that, the air in the door cylinder 10 is closed so that the door 5 can be closed by hand. It should be removed.

The reason for this is that if the solenoid valve 23 is driven even after the driver is seated in the position without starting, the air remaining in the air tank 2 is continuously supplied to the door cylinder 10 so that the door ( 5) Since the state cannot be closed, the solenoid valve 23 is stopped after a predetermined time (6 seconds).

As described above, the door opening and closing device for a passenger car of the present invention is provided with an operation switch and a timer composed of three ports, the opening and closing of the door and the door lock cylinder, and a neutral, and the cylinder of the door and the cylinder. The barrel is installed inside the door hinged to reduce the installation cost by using a low cost and simple pneumatic cylinder, and the door of the passenger car can be opened and closed automatically using the existing remote control device. It can be opened and closed freely with both automatic and manual, and by opening and closing the door smoothly without interference when the door is opened and closed, there is a very useful effect that a user with a disability or object can conveniently use a car.

In the present invention, by separately installing the air withdrawal valve in the air tank by using the air filled in the air tank to clean the inside and outside of the vehicle, or by connecting the air tool, each air tool can be used, the tire is flat In this case there is another effect that can be easily carried out replacement of the tire.
