Description

[Detailed Description of the Invention] The present invention relates to an improvement in an unlocking operation device for unlocking automobile doors all at once from a remote location.

As is well known, various proposals have been made for automatic door lock devices for automobiles, and a typical one has a configuration as shown in the first drawing. That is, in FIG. 1, the part surrounded by a broken line represents the driver's side door D, and the symbols M ₁ , M ₂ , and M ₃ represent the door lock actuators of the other passenger side doors. The actuators M ₁ , M ₂ , and M ₃ are a lock switch S ₁ and an unlock switch that are sensitive to the key cylinder position and the inside lock knob position of the driver's side door D.
The locking switch S _{1 and} the unlocking switch S 2 are actuated in the corresponding direction by the command of S 2 (the locking switch S ₁ and the unlocking switch S ₂ are
It is always open, but only momentarily when the key cylinder or inside lock knob is operated.
It is a temporary switch that closes and then opens). Therefore, in such an automatic door lock device, the door lock actuators M ₁ , M ₂ , M ₃ of the passenger side door are activated in response to a key operation or an inside lock knob operation on the driver side door D.
will be operated in the corresponding direction (see ``Automotive Engineering Complete Book Volume 13 Passenger Car Body'' published by Sankaido Co., Ltd.).

However, in such an automatic door lock device, even if only the driver's door D needs to be unlocked, all the other passenger side doors are unlocked, so the unlocking sound becomes noisy. In order to solve these problems, the applicant filed a patent application filed in 1983.
-152929 (Japanese Patent Application Laid-open No. 59-41574) discloses a two-step operation of the inside lock knob on the driver's side door, that is, by operating the inside lock knob in one step, the driver's side door is unlocked. proposed an automatic door lock device that unlocks the door lock on the other passenger seat side by further overstroke.

By the way, in recent luxury cars, the driver's side door can be opened regardless of whether it is locked by operating the inside handle while the driver's side door is locked, taking into account the convenience of the driver getting out of the car. Some models use an override door lock on the driver's side door. However, if a two-step automatic door lock device such as that of the prior invention is applied to a door lock device having such an override type door lock, when the inside handle of the driver's side door is pulled, the inside lock of the driver's side door will be locked. The knob is in the unlocked state, but this inside lock knob is in a state where it does not operate the door lock actuators M ₁ , M ₂ , M ₃ of the other passenger side doors, that is, the inside lock knob of the door lock of the driver's side door is in the unlocked state. Door lock actuators M ₁ , M ₂ , M ₃ for other passenger side doors
The driver's side door is opened while the driver's side door is kept in the "locked state", so in order to unlock the other passenger's side doors as well, after unlocking the driver's side door D using the inside handle, The inside lock knob of the driver's side door D had to be operated by overstroke each time, which was a hassle, and it was difficult to adopt it right away.

In consideration of the operability of the automatic door lock device with an override function when unlocking the passenger side door as described above, the present invention is designed to lock the passenger side door all at once by simply operating the inside handle of the driver's side door. The purpose of this system is to create a structure that can be unlocked, and a detector is installed facing the inside handle of the driver's side door that is sensitive to the overstroke position beyond the door release position, and the door is locked using the signal from the detector.・It is proposed to operate the actuator in the unlocking direction.

Embodiments of the present invention will now be described in detail with reference to FIGS. 2 and 3.

FIG. 2 is an electrical circuit diagram corresponding to FIG. 1 of the unlocking device according to the present invention, and the same reference numerals are given to the same structural parts as in FIG. 1. The feature of the present invention is that the actuator operating switch _S3 (detector) is installed electrically in parallel with the unlocking switch _S2 on the driver's side door D. That is, this actuator operating switch _S3 is built into the inside of the driver's side door D, facing the inside handle H of the door D, as shown in the third figure, and the inside handle H is located at the door opening position shown by the two-dot chain line. When it is manually operated in the direction of the arrow to the overstroke position shown by the one-dot chain line, it is closed.

Since the unlocking operation position according to the above embodiment is configured as described above, all the doors are opened and closed at the same time by opening and closing the locking switch _S1 and the unlocking switch _S2 using the key cylinder or inside lock knob of the driver's side door D. Of course, it can be locked and unlocked. When the driver exits the vehicle, the driver's side door D
By manually operating the inside handle H, the driver's side door D can be released. However, when the inside handle H is pulled beyond this door release position to the position shown by the dashed line, the actuator operation switch _S3 is activated. Close and door lock actuator
Since M ₁ , M ₂ , and M ₃ operate in the unlock direction,
The door locks of the other passenger side doors become unlocked all at once.

As is clear from the above explanation, according to the present invention, the passenger side doors other than the driver's seat can be unlocked all at once by simply operating the inside handle of the override door lock. Since the detection is performed when the inside handle overstrokes beyond the door release position, a highly safe unlocking operation can be achieved.
