Abstract

The present invention relates to a door lock device for a child protection vehicle, and an operating lever connected to the rear end of the operating lever for releasing the latch arm installed in a conventional door locking system, and a control switch for operating the actuator for operating the operating lever; The actuator is operated by the drive switch and the control switch by installing the above control switch next to the driver with a drive switch connected in parallel to the control switch and a collision and rollover detection sensor providing an input signal to the drive switch.

Description

Door lock for car infant protection

Conventional vehicle child protection door lock device as shown in Figure 1 as the structure to manually operate the operation lever of the rear door, after closing the door can not be released by the operation of the inner handle in the room not only must be opened outside. In the event of a car crash or rollover, even if the passengers were conscious, they could not grab the operating lever hidden in the gap of the door, so they could not escape and had to be rescued from the outside. I'm doing it.

The present invention, in view of the above-mentioned shortcomings, the driver sits in the driver's seat and locks or releases the child protection door lock device by simple switch operation to improve the convenience of getting on and off in the adult, and the locking device is detected by the sensor detection in case of overturn or collision It is released and the child protection door lock device driven by the switch operation in order to enable the escape of the internal rider without external rescue work, including a rollover and a collision detection sensor is completed as a child protection door lock device that is automatically released at this time.

Hereinafter, the gist of the present invention will be described in detail with reference to FIG.

As in the normal door locking system, the operation lever 2 for releasing the latch arm 1 is operated by the shaft 3, and the operation lever 4 at the rear end of the operation lever 2 is operated. The actuator 5 is connected to the latch arm side of the operation lever 2.

The actuator 5 is ground to one side, the input terminal is released and the lock is a connection across the contacts of the control switch (SW ₁₎ and a control switch (SW ₁₎ is connected to the power supply and simultaneously a driving switch (SW ₂₎ The drive switch SW ₂ is connected in parallel with the input terminal of the actuator 5.

In addition, the drive switch SW ₂ is configured in a circuit such that the drive switch SW ₂ is turned on by the collision and rollover detection sensor 6 installed at any place of the vehicle body.

The operation of the present invention thus described will be described.

When all the passengers normally ride in the room and there is an infant, when the infant rides, the driver contacts the adjustment switch (SW ₁ ) to the lock side to operate the actuator 5 in the forward direction and pulls the latch arm (1).

Then, the latch arm 1 locks the infant restraint so that safety measures are taken so that the door does not open even when the infant pulls the mermaid handle of FIG. 1.

When the vehicle arrives at the destination, the driver switches the control switch SW ₁ to the release position.

Then, the actuator 5 operates in the reverse direction to push the latch arm 1 to release the infant restraint device so that the door can be opened by the mermaid handle (FIG. 1).

If the vehicle is overturned or crashed due to an accident, even if the driver loses consciousness and cannot operate the control switch SW ₁ , the collision and rollover detection sensor 6 signals and drives the drive switch SW ₂ . By contacting, the power is applied in parallel to the actuator 5 to operate the actuator 5 in the reverse direction (release) so that the door can be opened both inside and outside.

Of course, it can also be operated manually as in the prior art outside the operation lever (4).

In the present invention as described above, safety measures are established once in a vehicle in which an infant rides, and the inconvenience of manually opening and closing the door from the outside is eliminated daily, and in particular, the door lock is automatically released in a crash and rollover accident. It can be put into practical use as a second third safety device in preparation for a safety accident.

The present invention relates to an automobile child protection door lock device, and more specifically, to allow the rear seat occupant or driver to get on and off to electrically open and close the infant protection door lock device without the need for opening and closing operation, thereby improving the convenience and convenience of getting on and off the rear seat. In the event of an accident such as side rollover or complete rollover, it is possible to prevent the occurrence of second and third accidents by allowing the internal rider to escape directly and take follow-up measures without external rescue work.

Claims (1)

On the control lever to operate the actuator which is connected to the rear end of the operation lever for unlocking the latch arm installed in the normal door lock system, and the actuator to operate the operation lever, and the drive switch and the drive switch connected in parallel to this control switch. And a collision and rollover detection sensor that provides an input signal, and the actuator is operated by the drive switch and the control switch by installing the control switch next to the driver.
