  However, in the above-described conventional example, when the design cover that is manually operated is functioned as a member for inserting the first detection switch, for example, if the push-in depth of the design cover is shallow, the first detection switch is in the ON state. There is a case where it does not transition to, and there is a problem of lack of reliability. In addition, this problem can be solved by reducing the rotation stroke of the design cover until the first detection switch is turned on. However, in this case, the insertion space for the hand in the opening is narrowed. The operation space for the operation member for turning on the detection switch 2 is reduced, and the operability is lowered.

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

According to the present invention, the object is
A door opening operation device for unlocking the unlocked door latch device 1 fixed in a vehicle door,
A latch release operation portion 4 disposed at a position in the door operable from an opening 3 opened in the outer panel 2 of the door and capable of performing a latch release operation of the door latch device 1;
A cover body 5 that is movable from a closed position for closing the opening 3 into the door and is movable to an open position for opening the opening 3;
This is achieved by providing a door opening / closing operation device for a vehicle having a cover driving electric actuator 6 for driving the cover body 5 from the closed position to the open position on condition that authentication of the user's use authority is established.

  In the present invention in which the opening 3 opened in the outer panel 2 of the door is covered with a cover body 5 and the cover body 5 is retracted into the door when the door is opened, the outer panel 2 of the door is not uneven. It becomes possible to improve the aesthetics.

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

  Furthermore, since the cover body 5 is drawn into the door and does not protrude to the outside of the outer panel 2 due to the establishment of the authentication, it is not necessary to consider the restriction of the protruding dimension from the outer panel 2, so the degree of freedom in design Can be increased. An authentication signal output from a portable key possessed by the user can be used to authenticate the use authority of the user.

  In addition to the movement of the cover body 5 to the open position by the establishment of the authentication, the door latch device 1 can be configured to transition to the unlocked state. In this case, the operation of the cover body 5 is performed by 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 performed smoothly. On the other hand, when the cover body 5 does not operate, it is assumed that the battery will run out. Therefore, it can be used as a sign for prompting a manual operation described later.

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

  In the present invention, the cover body 5 can be manually rotated to the latch release position beyond the open position, and the second latch release operation portion 7 is operated by the operation up to the latch release position to latch the door latch device 1. Can be released.

  As a result, the door opening operation can be performed in an emergency evacuation manner even when the battery has run out.

  The manual movement of the cover body 5 in the direction of the latch release position is performed when authentication is established or when the movement of the cover body 5 is locked to the cover body 5 by operating the cylinder lock 8 with the key insertion hole exposed on the outer panel 2 of the door. Although it is possible to completely prevent the operation of the cover body 5 due to mischief or the like on the condition of the release, if the manual opening operation to the cover body 5 is unconditionally allowed as in the present invention, it is rarely very Since it is possible to simplify the procedure for the time operation, the usability is improved.

  Further, since the cover body 5 is rotated, if the distance between the point of application to the second latch release operation portion 7 and the center of rotation of the cover body 5 is appropriately set, the manually pressing operation force of the cover body 5 is increased. Since the lever ratio can be increased, the push-in operability is improved.

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

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

  The cylinder lock 8 can be arranged with its 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 at a position where it can be operated, the cylinder lock 8 is not exposed to the outside of the outer panel 2 except during the door opening operation, so that the degree of freedom in designing the door is improved.

  The latch release operation unit 4 may be, for example, a lever that is manually operated. However, if a drive switch of an electric actuator is arranged, the operation becomes simple.

Furthermore, as another aspect of the present invention for achieving the above object,
The cover body 5 constitutes a door opening / closing operation device for a vehicle in which an electrode 11 of a capacitance sensor 10 for opening the door that serves as an authentication operation start switch by contact with an exposed surface of the cover body 5 is arranged. can do.

  According to the present invention, an authentication operation is started simply by touching the cover body 5 by the user, and when the authentication is established, the cover body 5 is moved to the open position. When the capacitance sensor 10 is arranged on the back surface of the cover body 5, exposure to the outside can be prevented, 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.

  As shown in FIG. 1 and subsequent figures, the door opening / closing operation device has a base body 13 and a cover body 5 rotatably connected to the base body 13, and by fixing the base body 13 in the door by appropriate means. Mounted on the vehicle door.

  The cover body 5 has a plate portion 5a and rear surfaces of both front and rear ends of the plate portion 5a (hereinafter, in this specification, the vehicle length direction, that is, the left-right direction in FIG. The front and rear sides of the vehicle in the vehicle width direction are referred to as “front”, and the in-vehicle direction is referred to as “back”. The leg 5b is connected to the base body 13. In the connected state to the base body 13, the cover body 5 is freely rotatable around the rotation axis (C5) between the closed position shown in FIG. 3 (a) and the latch release position shown in FIG. 3 (c). The door is held in the closed position in a normal state where no opening operation to the door is performed.

  In order to hold the cover body 5 in the closed position in the normal state, the cover body 5 is urged to the closed position side by a torsion spring 5c wound around the rotation shaft (C5), and is further moved back and forth from the leg 5b. The driven blade piece 5d projecting from the base abuts against the drive pin 14a of the cover drive unit 14 mounted on the base pair 13, and the rotation stroke to the closed position side is regulated (see FIG. 4A).

  Further, as will be described later, in this example in which the latch release operation of the door latch device 1 by manual operation to the cover body 5 is allowed, the leg portion 5b has a latch generated in the cover body 5 due to inertial force due to a side collision. A weight mounting portion 5e for mounting a counterweight (W) for offsetting the moment in the release position direction is provided.

  As shown in FIG. 1A, the plate portion 5a of the cover body 5 is formed in a front view shape substantially the same as the opening 3 opened in the outer panel 2 of the door, and when the cover body 5 is in the closed position, The said opening 3 is obstruct | occluded and the design without an unevenness | corrugation as a whole is implement | achieved on the door surface in this state.

  In addition, an electrode 11 of a later-described electrostatic capacitance sensor 10 for opening the door is fixed to the central portion of the back surface of the plate portion 5a, and the electrostatic capacitance sensor 12a for closing that constitutes a switch 12 for closing operation is provided above the electrode 11. The electrode 12b is fixed.

  The cover drive unit 14 includes a motor as the cover driving electric actuator 6 and a rotating cam 14c that is driven to rotate about the rotation center by the cover driving electric actuator 6 through the gear train 14b. The drive pin 14a described above is erected.

  As described above, when the cover body 5 is in the closed position, the driven blade piece 5d of the cover body 5 is in contact with the drive pin 14a of the cover drive section 14 as shown in FIG. When the cover driving electric actuator 6 is driven, the rotating cam rotates clockwise in FIG. The driven blade piece 5d of the cover body 5 is pushed by the drive pin 14a by the movement of the drive pin 14a accompanying the rotation of the rotary cam 14c, and the cover body 5 rotates counterclockwise. FIG. 4 (b) shows the rotation end position by the cover drive unit 14, and this position is intermediate between the closed position shown in FIG. 3 (a) and the latch release position shown in FIG. 3 (c). This corresponds to the open position shown in FIG.

  When the cover driving electric actuator 6 is driven in reverse from this state to the state shown in FIG. 4A, the cover body 5 is in the closed position while maintaining the pressure contact state with the drive pin 14a by the restoring force of the torsion spring 5c. Return to.

  Furthermore, as shown in FIG. 4, the driven blade piece 5 d of the cover body 5 and the drive pin 14 a are not in a connected state, and the driven blade piece 5 d is pressed and driven by the drive pin 14 a to drive the cover body 5. Therefore, even if the cover driving electric actuator 6 is not operated due to a failure or battery exhaustion, the cover body 5 is manually operated without receiving the resistance of the cover driving electric actuator 6. Can be operated with.

  A pressing portion 15 is formed on the leg portion 5 b of the cover body 5, and a second latch release operation portion 7 that is driven by the movement of the pressing portion 15 accompanying the rotation of the cover body 5 is mounted on the base body 13. . In this example, the second latch release operation portion 7 is a lever-like member connected to the base body 13 by the rotation shaft 7a, and is vertically rotatable around the rotation shaft 7a in the connected state.

  The second latch release operating portion 7 is urged clockwise in FIG. 1B by the torsion spring 7b, and is held at the initial position shown in FIG. 1B by a stopper (not shown).

  In addition, the second latch release operation portion 7 has a pushed portion 7c bent at one end with respect to the rotating shaft 7a and a connecting portion 7d provided at the opposite end, and a rod rod is used as a transmission means to the door latch device 1. In this example used, a rod holder is used for the connecting portion 7d.

  Further, as shown in FIGS. 3 (b) and 5 (a), the pushed portion 7c of the second latch release operation portion 7 is moved to the initial position. In this state, when the cover body 5 is rotated to the open position, the pressing portion 15 of the cover body 5 is disposed at a position where it abuts.

  When the cover body 5 is further rotated from this state to reach the latch release position, the second latch release operation part 7 is pushed by the pressing part 15 and rotates counterclockwise in FIG. Then, the process shifts to the latch release position shown in FIG.

  Further, in the present example in which the lower end of the cover body 5 moves in the back direction and moves to the open position, the base body 13 is formed with a handle 16 along the lower edge of the opening 3, and the handle 16 The latch release operation unit 4 is disposed at the center of the. In this example, the latch release operation unit 4 is formed by a button switch including an oval push button 4a.

It is appropriately controlled by the unit 19.

  The authentication device 18 authenticates the use authority of the user by authenticating a portable key (not shown) possessed by the user of the vehicle, and contact with the plate portion 5a of the cover body 5 in the closed position is the electrode 11. When the door opening capacitance sensor 10 is detected, a request signal is output to the portable key. The portable key that has received the request signal outputs a response signal including ID information. If the ID information matches that registered in advance, the authentication device 18 outputs an authentication establishment signal.

  Upon receiving the authentication establishment signal from the authentication device 18, the control unit 19 drives the cover driving electric actuator 6 in the opening direction and outputs an unlocking signal to the latch releasing electric actuator 9 to unlock the door latch device 1. Transition to the state.

  As described above, by driving the cover driving electric actuator 6, as shown in FIG. 4, the cover body 5 rotates so as to be drawn into the door and moves to the open position, and the opening 3 of the outer panel 2 is externally moved. It will be in the state opened to.

  As the cover body 5 moves to the open position, as shown in FIG. 6B, the electrode 12b of the closing capacitance sensor 12a fixed to the upper end of the plate portion 5a is placed on the opening 3 of the outer panel 2. Move closer to the edge. In this state, when the user touches the upper edge of the cover body 5 and contact is detected by the closing capacitive sensor 12a, the control unit 19 reversely drives the cover driving electric actuator 6 so that the cover body 5 is moved. Move to closed position.

  The door latch device 1 is capable of transitioning between the locked state and the unlocked state, and the latch is shifted only from the unlocked state to the latch released state in which the lock with the striker is released from the locked state with the door striker. Can do. As described above, when the cover body 5 is in the open position, the door latch device 1 is in the unlocked state. When the switch that is the latch release operation unit 4 is pressed in this state, the latch release electric actuator 9 is moved. The door latch device 1 is driven to shift to the unlocked state. When the door latch device 1 shifts to the unlocked state, the door to which the back pressure is applied by packing or the like moves slightly in the opening direction, and the door is opened by pulling the handle 16 formed on the base body 13 from this state. It can be opened.

  Further, the cylinder lock 8 and the second latch release operation portion 7 are connected to the door latch device 1 through an appropriate transmission member such as a rod, and the door latch device 1 is unlocked by the unlocking operation to the cylinder lock 8. Can be migrated to.

  After the door latch device 1 shifts to the unlocked state, when the cover body 5 is further pushed in manually and rotated to the latch release position, the second latch release operation unit 7 rotates clockwise in FIG. It is possible to shift to the unlatched state.

  Therefore, in this example, even if the cover driving electric actuator 6 or the like does not operate due to battery exhaustion or failure, the cover body 5 is first pushed manually and then the cylinder lock 8 is unlocked. Furthermore, the latch release operation of the door latch device 1 can be performed by pushing the cover body 5 further.
