Vehicle door opening/close device
A vehicle door opening device that enables a door, in a lock state, to open comprises an operating unit. The operating unit comprises a first outside lever that is pivotally mounted, via a first shaft, and rotates with an outside handle; a second outside lever that is pivotally mounted, via a second shaft that differs from the first shaft, releasing action of the second outside lever is made by a release electric power source, the second outside lever is connected to the first outside lever so that the releasing action is not transmitted to the first outside lever; and a release lever that is pivotally mounted, via the second shaft, and carries out releasing action caused by the releasing action of the second outside lever so that the releasing action of the releasing lever can be transmitted to door latch units.
1. A vehicle door opening device comprising:
door latch units that hold a door closed;
a release electric driving source that releases the door latch units to enable the door to open;
a door-opening electric driving source that can open and close the door;
an outside handle provided on an external side of the door;
a locking electric driving source;
an operating unit that comprises a locking mechanism that can be shifted by the locking electric driving source between an unlock state where an action of the outside handle can be transmitted to the door latch units and a lock state where the action of the outside handle cannot be transmitted; and
a control that controls the release electric driving source, the door-opening electric driving source, and the locking electric driving source;
wherein the operating unit further comprises:
a first outside lever that is pivotally mounted to a base member via a first shaft and rotates in response to the action of the outside handle;
a second outside lever that is pivotally mounted to the base member via a second shaft differing from the first shaft, wherein the door latch units are released by a releasing action of the second outside lever caused by the release electric driving source, and wherein the second outside lever is connected to the first outside lever so that the releasing action of the second outside lever is not transmitted to the first outside lever; and
a release lever that is pivotally mounted via the second shaft, wherein a releasing action of the release lever is caused by the releasing action of the second outside lever when the locking mechanism is in the unlock state, so that the releasing action of the release lever is transmitted to the door latch units.
2. The vehicle door opening device according to claim 1 , wherein the second outside lever transmits its releasing action to the release lever via the locking mechanism when the locking mechanism is in the unlock state.
3. The vehicle door opening device according to claim 1 , wherein, when the door is in a full-closed position and the locking mechanism is in the lock state, an outside-handle detecting switch detects a return of the outside handle after the outside-handle detecting switch detects the action of the outside handle, so that the control carries out an unlocking control of the locking electric driving source, a releasing control of the release electric driving source to cause the releasing action of the second outside lever, and an opening control of the door-opening electric driving source.
4. The vehicle door opening device according to claim 3 , wherein, when the door is in the fully-closed position and the locking mechanism is in the unlock state, the outside-handle detecting switch detects the action of the outside handle, so that the control carries out the releasing control of the release electric driving source and the opening control of the door-opening electric driving source.
5. The vehicle door opening device according to claim 3 , wherein, when the door is in a fully-open position, whether the locking mechanism is in the unlock state or in the lock state, the outside-handle detecting switch detects the action of the outside handle, so that the control carries out the releasing control of the release electric driving source and a closing control of the door-opening electric driving source.
6. The vehicle door opening device according to claim 3 , wherein, when the door is in a position between a fully-open position and the fully-closed position, whether the locking mechanism is in the unlock state or the lock state, the outside-handle detecting switch detects action of the outside handle, so that the control does not carry out the releasing control of the release electric driving source, but carries out the opening control of the door-opening electric driving source.
7. The vehicle door opening device of claim 3 , wherein, when a time for detecting the action of the outside handle with the outside-handle detecting switch is shorter than a predetermined time, the control does not carry out the unlocking control of the locking electric driving source, the releasing control of the release electric driving source, and the opening control of the door-opening electric driving source.
8. The vehicle door opening device according to claim 1 , wherein the locking mechanism comprises a first lock lever that is pivotally mounted to the base member via a third shaft, a second lock lever that is pivotally mounted to the base member via the third shaft for the first lock lever and has an elongate hole, and an engagement pin that engages with the elongate hole of the second lock lever so as to be slidable relative to each other.
