Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an unlocking operation device for an automobile door lock, which is particularly suitable for a driver's side door of an automobile.

[Conventional technology]

In general, a locking / unlocking mechanism of a door lock on a driver's side door of an automobile is an electric actuator composed of a motor, a reduction gear, a clutch, etc., so that the locking / unlocking operation is automatically performed by sensing the vehicle speed. Even if the locking / unlocking mechanism is in the locked state so that the door can be unlocked from the vehicle interior while being connected, the locking / unlocking operation can be performed by releasing the inside handle provided on the vehicle interior side of the door. The mechanism is canceled from the locked state to the unlocked state, and at the same time, the door can be opened from the outside of the vehicle with the override structure that allows the door to be opened by releasing the meshing of the meshing mechanism. If you close the door in the locked state with the door open to prevent it from being locked, the locked state will be canceled. And a self-canceling structure which is adapted to return operating the lock state.

[Problems to be solved by the device]

In the conventional locking / unlocking mechanism override structure as described above, the engagement of the meshing mechanism is released by the operation of the inside handle, and the operation causes a part of the locking / unlocking mechanism to interfere, forcibly unlocking. Since the cancel operation is performed in the state, there is a problem that the operation during the overriding operation becomes heavy and the operation feeling changes from that during the normal operation.

Also, in the self-cancellation structure, if the door is closed with the door open and locked, a part of the meshing mechanism vigorously collides with the locking / unlocking mechanism as the door closes, forcing the locking / unlocking mechanism. In order to cancel the operation to the unlocked state dynamically and vigorously, an impact sound may be generated, and the actuator connected to the locking / unlocking mechanism is interlocked with the canceling operation and vigorously reverses from the output side. It is indispensable to mount a clutch so that the rotation from the output side is not transmitted to the motor side, resulting in an increase in actuator cost.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to improve the ability of the override operation and the self-cancel operation and to simplify the structure of the door lock and the actuator. An object of the present invention is to provide an unlocking operation device for an automobile door lock that can be realized.

[Means for solving the problem]

In order to achieve the above-mentioned object, the device of the present invention has a lockable and unlockable position in which an outside handle provided on the vehicle exterior side of the door cannot be operated to unlock the door and an unlockable position in which the door can be unlocked. By linking the lever with the actuator, it is possible to move the locking / unlocking lever between the locking position and the unlocking position by the operation of the actuator.
Also, in the unlocking operation device of the vehicle door lock, which is capable of unlocking the door regardless of the position of the locking / unlocking lever by the door unlocking operation of the inside handle provided inside the door, the locking position of the locking / unlocking lever. A lock detection switch for detecting a door release operation of the inside handle, a handle detection switch for detecting a door release operation of the inside handle, a door opening / closing detection switch for detecting opening / closing of the door, a lock detection position of the lock detection switch, and the handle When the operation switch detects a door release operation, the actuator can be operated in the unlocking direction, the lock detection switch detects the lock position, and the door open / close detection switch changes from the door open detection state to the door close detection state. And a control circuit enabling the actuator to operate in the unlocking direction when switched to It is characterized by a door.

[Action]

When the lock detection switch detects the locking position of the lock / unlock lever, if the inside handle in the vehicle compartment is released and an override operation is performed, the door lock is released, the door is opened, and the handle detection switch is released. By detecting the release operation of the inside handle, the actuator connected to the locking / unlocking mechanism is unlocked and the locking / unlocking lever can be cancelled to the unlocked position. At this time, the operating force of the inside handle is sufficient to release the door lock.

When the door is opened and the door is closed with the locking / unlocking lever in the locked position, the lock detection switch detects the locked state, and the door open / close switch detects the door closed, causing the actuator to unlock. Upon activation, the locking / unlocking lever is moved to the unlocking position, and so-called self-cancellation is performed.

The door is restrained in the closed state. At the same time, the door switch (19) detects that the door is closed and is turned on, so that the timer (25) outputs an on signal for a predetermined time. As a result, the logical product of the AND circuit (24) is obtained, an ON signal is output from the OR circuit (22), the motor (20) is activated via the relay circuit (21), and the output of the actuator (16). When the member (16a) operates in the unlocking direction, the locking / unlocking mechanism (6) is cancelled in the unlocked state.

[Effect of device]

According to the present invention, during the override operation,
Since the operating force for canceling the locking / unlocking lever to the unlocked position is not added to the operation of the inside handle, the operability is improved.

Further, the self-cancellation operation is performed by operating the actuator by combining the states of the two switches, that is, the lock detection switch and the door opening / closing detection switch. As in the conventional case, the door closing operation is performed. Since the movement of the door at the time is not used as a power source, a part of the meshing mechanism violently collides with the locking / unlocking mechanism when the door is closed, and an impact sound is generated, or the locking / unlocking mechanism is released. In order to prevent the actuator connected to the actuator from being reversely rotated from the output side vigorously in conjunction with the cancel operation, it is necessary to provide the actuator with a clutch that blocks the transmission of rotational force from the output side to the motor side. Therefore, the structure of the actuator and the door lock can be simplified.
