Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a safety device for a vehicle equipped with an automatic door lock device.

In recent years, from the perspective of improving safety, vehicles equipped with automatic door locking devices that detect vehicle speed and automatically lock all doors have become popular. In such cases, all doors remain locked, making it extremely difficult to rescue injured people from the outside, or making emergency escape from a submerged vehicle difficult. There is.

The present invention attempts to deal with such a problem, and its main purpose is to automatically release the door lock device when a collision, fall, etc. occur, while the vehicle is stationary after the accident. In addition, if the vehicle is equipped with a power window device, this safety device automatically opens the window glass to facilitate rescue of occupants from the outside and also facilitates emergency escape from the passenger compartment. Our goal is to provide the following.

An embodiment of the present invention will be explained below with reference to the drawings.
In the figure, reference numeral 10 indicates an unlocking circuit of a known automatic door locking device installed in a vehicle, and reference numeral 30 indicates an unlocking circuit of a known door locking device for a child protector. It shows the mowing power circuit for opening the window glass in the device. Each of these circuits 10, 20 and filter 0 is a manual switch 8W1.
, Ignition switch 8 via BW216w3
W, and the ignition switch 8W4 is connected to the vehicle battery power supply B.

The lock release circuit 10 includes an electromagnetic coil 11.1 for unlocking a door lock device assembled to both doors at the front of the vehicle compartment.
2 and electromagnetic coils 13 and 14 for unlocking the door lock device assembled on both doors at the rear of the vehicle compartment, and these electromagnetic coils 11 to 14 are connected to a manual switch 8Wl.
When the door is closed, it energizes and unlocks each door lock device.

The lock release circuit 20 includes electromagnetic coils 21 and 22 for unlocking a child protector door lock device provided on each door located on both sides of the rear seat of the vehicle, and these electromagnetic coils 21 and 22 are operated by a manual switch. When SW2 is closed, electricity is applied to unlock each child protector door lock device. Window glass opening energizing circuit 3
0 is connected to electric motors 31, 32, 33, and 34 that drive power window devices assembled to each door of the vehicle interior, and these electric motors 61 to 34 are started in reverse when the manual switch 8W3 is closed. and open the windows of each door.

The safety device of the present invention includes each of the above lock release circuits 10.2.
0 and a window glass opening energizing circuit 30, and its main components include an impact detection sensor 41.
This is because a stationary state confirmation circuit 42 and a control circuit 46 are provided. In this configuration, the impact detection sensor 41 is installed in a part of the vehicle body so as to detect the impact applied to the vehicle body when the vehicle collides or falls and generates an output signal, and is connected to the power source B via the ignition switch 8W4. is connected to. The stationary state confirmation circuit 42 is connected to the impact detection sensor 41 so as to operate in response to the output signal of the impact detection sensor 41, detect when the vehicle comes to rest after a collision, and generate an output signal t'ifs. .

The control circuit 43 also includes slow-acting relays "l+R2+R3" connected to the stationary state confirmation circuit 42, and normally open switches 8W5, 8W6, and 8W7 that are closed by the operation of these slow-acting relays ttl, RQ, and R3. , 8W5, 8W6, and 8W7 serve to connect the above-mentioned lock release circuits 10.20 and the window glass opening energizing circuit 30 to the power source B when the normally open switches 8W5, 8W6, and 8W7 are closed.

According to the safety device configured as described in 1-, when the vehicle causes a collision or falls, the impact detection sensor 41 detects the impact and generates an output signal, and in response, stops the vehicle. The state confirmation circuit 42 is activated and when the vehicle comes to a standstill after a collision or fall, the stationary state confirmation circuit 42 generates an output signal.

As a result, each slow-acting relay turtle of the control circuit 43.

It2. When R3 is activated and a predetermined delay time has elapsed, each normally open switch 8W5.8W6. Close sw7. For this reason, each lock release circuit 10.20 and the window glass opening energizing circuit 60 are connected to the power source B and energized, and each lock device that has been automatically activated when the vehicle is running is released, and each The window glass of the door is opened.

As understood from the above explanation, in the safety device of the present invention, the impact detection sensor (41) exemplified in the above embodiment detects the impact when the vehicle collides or falls, and the stationary state confirmation circuit (42) is activated, and the control circuit (46) is activated after a predetermined delay time by the output signal of the stationary state confirmation circuit (42).
) and power window device window glass opening circuit (30
) It is characterized by the fact that it is energized, which allows occupants of vehicles that have collided or fallen to be easily rescued from the outside, and also allows occupants to escape from the window of a submerged vehicle in an emergency. .
