However, in the above-mentioned conventional example, when the manually operated design cover functions as a member for turning on the first detection switch, for example, when the push-in depth of the design cover is shallow, the first detection switch is in the ON state. There is a problem that it lacks reliability because it may not transition to. Further, this problem can be solved by reducing the rotational stroke of the design cover until the first detection switch is turned on, but in this case, the space for inserting the hand in the opening is narrowed, so that the first detection switch is used. The operation space for the operation member for turning on the detection switch of 2 is reduced, and the operability is deteriorated.

The present invention has been made to eliminate the above drawbacks, and an object of the present invention is to provide a vehicle door opening / closing operation device having high operation reliability.

According to the present invention, the above object is
A door opening / closing operation device that is fixed inside the door of a vehicle and that unlatch-operates the unlocked door latch device 1.
A latch release operation unit 4 that is arranged at a position inside the door that can be operated from the opening 3 opened in the outer panel 2 of the door and that can operate the latch release of the door latch device 1.
A cover body 5 that can move from the closed position that closes the opening 3 to the open position that opens the opening 3 by moving into the door.
It has a cover drive electric actuator 6 that drives the cover body 5 from a closed position to an open position on condition that authentication for the user's usage authority is established.
The cover body 5 is provided with a vehicle door opening / closing operation device in which an electrode 11 of a door opening capacitance sensor 10 that serves as an authentication operation start switch by contact with an exposed surface of the cover body 5 to the outside is arranged. Achieved by doing.

In the present invention in which the opening 3 opened in the outer panel 2 of the door is covered with the cover body 5 and the cover body 5 retracts into the door during the door opening operation, the outer panel 2 of the door is not formed with irregularities. It becomes possible to improve the aesthetics of the door.

Further, the cover body 5 is moved from the closed position to the open position by the cover drive electric actuator 6 driven on the condition that the certification is established, and the stroke of the cover body 5 is not set as the certification operation start condition, so that the operation reliability is improved. Can be made to.

Further, since the cover body 5 is pulled into the door and does not protrude to the outside of the outer panel 2 due to the establishment of the certification, it is not necessary to consider the regulation of the protrusion dimension from the outer panel 2, so that the degree of freedom in design is high. Can be enhanced. An authentication signal output from the user's mobile key can be used to authenticate the user's usage authority.

Further, by establishing the certification, in addition to moving the cover body 5 to the open position, it is also possible to configure the door latch device 1 to transition to the unlocked state. In this case, the operation of the cover body 5 is the door latch. It also serves as a sign indicating the transition of the device 1 to the unlocked state, and subsequent operations can be smoothly performed. On the contrary, when the cover body 5 does not operate, it is assumed that the battery is dead, so that it can be used as a sign for prompting a manual operation described later.

Further, as another aspect of the present invention for achieving the above object,
The cover body 5 can be manually rotated from the closed position beyond the open position to the latch release position where the second latch release operation unit 7 arranged in the door is operated to release the latch of the door latch device 1. A vehicle door opening / closing operation device formed in the vehicle can be configured.

In the present invention, the cover body 5 is manually formed so as to be rotatable up to a latch release position beyond the open position, and the operation up to the latch release position activates the second latch release operation unit 7 to latch the door latch device 1. Can be released.

As a result, even when the battery is dead, the door opening operation can be performed as an emergency evacuation.

The manual movement operation of the cover body 5 in the latch release position direction is a state in which authentication is established or the movement to the cover body 5 is locked by operating the cylinder lock 8 having the key insertion hole exposed on the outer panel 2 of the door. It is possible to completely prevent the operation of the cover body 5 due to mischief or the like on the condition that the cover body 5 is released. Usability is improved because it is possible to simplify the procedure for operating the time.

Further, since the cover body 5 is rotated, if the distance between the point of action on the second latch release operation unit 7 and the rotation center of the cover body 5 is appropriately set, the manual pushing operation force of the cover body 5 can be obtained. Since it can be increased by using the lever ratio, the pushing operability is improved.

Furthermore, as another aspect of the present invention for achieving the above object,
It is possible to configure a door opening / closing operation device for a vehicle having a cylinder lock 8 that is arranged at a position inside a door that can be operated when the cover body 5 is in the open position and that causes the door latch device 1 to transition to the unlocked state. ..

A cylinder lock 8 that can be rotated by a genuine unlock key can be used for the operation of shifting the door latch device 1 to the unlocked state, which is necessary for the manual latch release operation.

The cylinder lock 8 can be arranged with the head exposed on the outer panel 2 of the door, but as in the present invention, the cylinder lock 8 is shielded by the cover body 5 in the closed position, and the cover body 5 rotates to the open position. If it is arranged in a position where it can be operated when the door is opened, the cylinder lock 8 is not exposed to the outside of the outer panel 2 except when the door is opened, so that the degree of freedom in door design is improved.

Further, the latch release operation unit 4 may be, for example, a lever or the like that is manually operated, but if the drive switch of the electric actuator is arranged, the operation becomes easy.

Further, in the present invention
An electrode 11 of the door opening capacitance sensor 10 that serves as an authentication operation start switch by contacting the exposed surface of the cover body 5 to the outside is arranged on the cover body 5.

According to the present invention, the authentication operation is started only by the user touching the cover body 5, and when the authentication is established, the cover body 5 is moved to the open position, so that the usability is improved and the door is opened. When the capacitance sensor 10 is arranged on the back surface of the cover body 5, it is possible to prevent exposure to the outside, so that the degree of freedom in design is improved.

According to the present invention, since the stroke of the cover body is not used as the authentication operation start condition, the operation reliability can be improved.
