It is designed so that 12 can be unlocked.

Reference numeral 14 denotes an open / close switch installed in an instrument panel or the like near the driver's seat. By operating the open / close switch 14, the control box 15 is provided with three types of signals for opening, closing, and neutral doors 2 under the passenger seat. The open / close switch 14 is a signal path for instructing the opening of the door 2.
16 is input to the delay circuit 17 in the control box 15, and the output side of the delay circuit 17 is connected to the opening operation side of the door 2 in the solenoid valve 7, and the timer of the delay circuit 17 is set when the door 2 is opened. Thus, the opening command of the opening / closing switch 14 is transmitted to the solenoid valve 7 after a predetermined time delay.

On the other hand, the signal path 18 for instructing the closing of the door 2 in the opening / closing switch 14 is directly input to the closing operation side of the solenoid valve 7 without passing through the delay circuit 17.

Reference numeral 19 denotes a rear warning indicator having a lamp to be controlled to be turned on. The rear warning indicator 19 is installed at a place where it is easily visible from the rear in the body 1 of the automobile, and "the door is opened / closed" etc. on its surface. The lighting signal path 20 for inputting to the rear warning indicator 19 is connected to the delay circuit 17 via the flicker circuit 21 provided in the control box 15. The rear warning indicator 19 is controlled to blink through the flicker circuit 21 during the operation of the delay circuit 17.

Reference numeral 22 denotes a buzzer that is connected in parallel with the rear warning indicator 19 to the lighting signal path 20 in the control box 15, and intermittently sounds in synchronization with the rear warning indicator 19 to the driver himself. It is designed to call attention before opening the door 2.

Reference numeral 23 denotes a courtesy switch installed on the pillar, and the courtesy switch 23 is connected to the delay circuit 17 so that the door 2
The door opens when the courtesy switch 23 is switched so that the delay circuit 17 does not work and the opening signal of the open / close switch 14 is directly input to the solenoid valve 7 when the detection signal is emitted. 2, the delay circuit 17 does not work during the opening operation from the middle open position, and the rear alarm indicator 19
It is made so that the warning of is not emitted.

Next, the operation of the safety device in the vehicle door opening / closing device according to the present invention will be described based on the operation chart of FIG.
First, when the open / close switch 14 is operated to the open side, such a signal is input to the delay circuit 17, the input to the solenoid valve 7 is held for a predetermined time by the action of the delay circuit 17, and the rear alarm is issued via the flicker circuit 21. An intermittent input signal is sent to the display device 19, which causes the rear warning display device 19 to blink, and allows a motorcycle or the like running behind to recognize that the door 2 is to be opened, and at the same time, it is installed in the vehicle. Buzzer 22
Sounds intermittently to call the driver's attention, and such a state continues for a predetermined time (about 2 to 3 seconds) and the delay circuit 17
When the action of is completed, the rear alarm indicator 19 and buzzer 22
At the same time when the alarm in (3) is stopped, a door open signal is sent to the solenoid valve 7 to open the door 2, and the courtesy switch 23 is switched to the open side of the door 2.

When the open / close switch 14 is operated to the neutral position during the opening operation of the door 2, the solenoid 2 controls the door 2 to stop at the open position at that time, and the door 2 is opened again from the stop position. With the courtesy switch 23, the door 2 is opened without the delay circuit 17 acting and no alarm being issued.

In order to operate the door 2 from the open state, the opening / closing switch 14 is operated to the closing side so that the circuit on the closing side does not go through the delay circuit 17, so that the door 2 is immediately closed.
