<Configuration of door handle device>
As shown in FIG. 1, an outside handle 10 (vehicle door handle) is disposed on an outer panel 9 forming a vehicle door 8 (vehicle door). The outside handle 10 is operated to open (close) the door 8 with respect to the vehicle body (not shown).

  As shown in FIG. 2, the door handle device 1 includes an outside handle 10, a door lock device 2 having a latch mechanism 2a (door opening / closing mechanism) and a lock mechanism 2b, an outside handle 10 and a latch mechanism 2a. A mechanical actuating part 3 that is electrically connected, and an electrical actuating part 4 that electrically connects the outside handle 10 to the latch mechanism 2a and the lock mechanism 2b. The latch mechanism 2 a is a mechanism that holds the door 8 in a closed state. The lock mechanism 2b can change between a locked state in which the operation of the latch mechanism 2a is inhibited and an unlocked state in which the operation of the latch mechanism 2a is permitted in a state in which the latch mechanism 2a holds the door 8 in the closed state. Mechanism.

<Configuration of outside handle (mechanical connection)>
As shown in FIG. 2, the outside handle 10 includes a handle grip 11 (gripping part) extending in the vehicle front-rear direction and a handle frame 12 extending in the vehicle front-rear direction. The handle frame 12 is disposed on the vehicle inner side of the outer panel 9. The handle frame 12 includes a curved portion 12a that is aligned with the concave portion 9a of the outer panel 9 in the vicinity of the center in the extending direction.

  The handle frame 12 is formed with a frame end 12d and a frame opening 12e on both sides in the extending direction across the curved portion 12a. On the other hand, in the outer panel 9, panel openings 9d and 9e are formed. In the state in which the handle frame 12 is fixed to the outer panel 9, the frame end 12d and the frame opening 12e are in the same positional relationship with the panel opening 9d and the panel opening 9e, respectively. A base 20 having an insertion hole 20c is connected to the frame end 12d.

  The handle grip 11 is disposed on the outer side of the outer panel 9 in the vehicle. The outside handle 10 includes a support arm 31 at the vehicle front end of the handle grip 11 and an operation arm 32 at the vehicle rear end.

  The operating arm 32 extends into the door 8 through the panel opening 9 e of the outer panel 9. Further, the operating arm 32 is engaged with a bell crank arm 33 (mechanical operating unit) at the inner end of the vehicle. The bell crank arm 33 is mechanically connected to the latch mechanism 2a of the door lock device 2 disposed in the door 8 by mechanical connection (mechanical operation part) such as a rod. That is, the bell crank arm 33 and a mechanical connection such as a rod constitute the mechanical operating unit 3.

  The support arm 31 extends into the door 8 through the insertion hole 20 c of the base 20 and the panel opening 9 d of the outer panel 9. The support arm 31 is rotatably supported by the shaft portion 20f of the support portion 20b of the base 20 held by the handle frame 12.

  A fixing portion 21 is disposed in the frame opening 12e at the vehicle rear end of the handle frame 12. The fixing portion 21 has a key cylinder 22. The key cylinder 22 is mechanically connected to the door lock device 2, and the lock mechanism 2b can be mechanically switched between a locked state and an unlocked state by a mechanical key. Here, the lock mechanism 2b is set to be unlocked when the vehicle receives an impact of a predetermined value or more in the locked state. The rear panel 9 of the handle frame 12 and the key cylinder 22 sandwich the outer panel 9. The front end of the handle frame 12 is fixed to the outer panel 9 via the base 20. In this way, the handle frame 12 is fixed to the outer panel 8. For this reason, the fixing portion 21 is provided on the outer panel 9 adjacent to the rear end of the handle grip 11 in the vehicle.

<Door opening operation (mechanical connection)>
When the door 8 is opened by the mechanical operating unit 3, the handle grip 11 is rotated to the outside of the vehicle with respect to the handle frame 12. At this time, since the handle grip 11 rotates around the shaft portion 20f of the support portion 20b, the operating arm 32 is moved in the vehicle outer direction, and the bell crank arm 33 engaged with the operating arm 32 is operated. As a result, the latch mechanism 2a of the door lock device 2 is mechanically operated, and the door 8 is opened with respect to the body.

<Configuration of outside handle (electrical connection)>
The latch mechanism 2a of the door lock device 2 is connected to an actuator 41 (electrical operation unit) that operates the latch mechanism 2a. The actuator 41 is controlled by an ECU 42 (electrical operating unit), and operates the latch mechanism 2a by an input signal from the ECU 42. The input signal is based on detection of a user operation of the opening operation switch 11a (detection unit) provided on the handle grip 11. That is, the actuator 41 and the ECU 42 constitute the electrical operating unit 4. Here, when the user having the electronic key operates the opening operation switch 11a, if the lock mechanism 2b is in the locked state, the ECU 42 activates the actuator 41 by authenticating the electronic key to lock the lock mechanism 2b. It is set to cancel the state at the same time.

<Door opening operation (electrical connection)>
When the door 8 is opened by the electrical operating unit 4, the opening operation switch 11a of the handle grip 11 is operated. At this time, the operation of the opening operation switch 11 a is recognized by the ECU 42, and the ECU 42 sends an input signal to the actuator 41. In response to the input signal, the actuator 41 operates the latch mechanism 2a, so that the door 8 opens with respect to the body.

<Outside handle configuration (detailed configuration)>
As shown in FIGS. 3 to 5, the fixing portion 21 has a stopper 50 (a rotation restricting portion, an engaging portion) that rotates as the key cylinder 22 is rotated by a mechanical key. The handle grip 11 has an engaged portion 51 (rotation restricting portion) with which the stopper 50 engages at the rear end of the vehicle, and the fixing portion 21 unlocks the stopper 50 (counterclockwise direction in FIG. 3). A rotation permission portion 52 that allows the rotation of the rotation.

  The vehicle rear ends of the fixed portion 21 and the handle grip 11 communicate with each other and have a substantially rectangular common hole portion 53 from the vehicle lower side to the upper side. A portion of the hole 53 located on the handle grip 11 is the non-engaging portion 51, and a portion located on the fixing portion 21 is the rotation allowing portion 52.

  As shown in FIG. 5, the stopper 50 extends from the key cylinder 22 toward the handle grip 11 in a normal state where the latch mechanism 2 a is operated by the opening operation switch 11 a to open the door 8, and the engaged portion 51 is engaged. And the fixing | fixed part 21 and the handle grip 11 are made into an engagement state, and rotation with respect to the outer panel 9 of the handle grip 11 is suppressed. Further, as shown in FIG. 4, the stopper 50 is disengaged from the engaged portion 51 in conjunction with the rotation of the key cylinder 22 in the unlocking direction. And the fixing | fixed part 21 and the handle grip 11 are made into a non-engagement state, and rotation with respect to the outer panel 9 of the handle grip 11 is accept | permitted. Thus, the stopper 50 and the engaged portion 51 constitute a rotation restricting portion 55, and the rotation restricting portion 55 rotates the key cylinder 22 from the outside of the vehicle to engage and disengage the engagement state. The state can be switched. Note that the key cylinder 22 has a well-known structure inside the key cylinder 22, and the stopper 50 does not move even when the key cylinder 22 is rotated in the locking direction using a mechanical key with the stopper 50 engaged with the engaged portion 51. Only the key cylinder 22 rotates in the locking direction without rotating in the locking direction (clockwise direction in FIG. 3) from the engaged state.

  Moreover, the stopper 50 has the fracture | rupture part 50a which fractures | ruptures when the force beyond a predetermined value is applied. Here, the force equal to or greater than the predetermined value is greater than the inertial force generated in the grip portion due to a side collision with the vehicle, and is, for example, a force of the mass of the handlebar grip 11 × about 30 N. As shown in FIG. 3, the breaking part 50a is configured to be more easily broken than other parts by providing a notch. Further, as shown in FIG. 5, the breaking portion 50 a is located at a portion of the stopper 50 corresponding to a position where the handle grip 11 and the fixing portion 21 are close to each other. Here, the breaking portion 50a does not necessarily need to be provided with a notch, and may be configured to be easier to break than other portions of the stopper 50 by changing the material or the like, and not only the breaking portion 50a but also the stopper 50 as a whole. You may comprise easily to fracture | rupture.

<Door opening operation (detailed configuration)>
In normal times, the user opens the door 8 by the electrical operation unit 4 which is the main opening operation method. The normal time is a state in which the stopper 50 always keeps the fixing portion 21 and the handle grip 11 in an engaged state and prevents the handle grip 11 from rotating relative to the outer panel 9. At this time, since the handle grip 11 is prevented from rotating, the mechanical operating unit 3 does not operate the latch mechanism 2a. Here, when the user having the electronic key operates the opening operation switch 11a, if the lock mechanism 2b is in the locked state, the ECU 42 activates the actuator 41 by authenticating the electronic key to lock the lock mechanism 2b. Release the state at the same time. When the lock state of the lock mechanism 2b is switched to the unlocked state by the electrical operating unit 4, the key cylinder 22 is not interlocked and does not rotate in the unlocking direction. Therefore, as a result, priority is given to the opening operation of the door 8 by the electrical operating unit 4.

  When the power supply is interrupted due to a battery down or the like, the electrical operation unit 4 cannot open the door 8. Therefore, the door 8 is opened by the mechanical operating unit 3 which is an opening operation method for fail-safe. More specifically, the user inserts the mechanical key into the key cylinder and rotates it in the unlocking direction, thereby releasing the lock state of the lock mechanism 2b and switching the rotation restricting portion 55 from the engaged state to the non-engaged state. Then, the door 8 is opened by the mechanical operating unit 3 by rotating the handle grip 11 that is allowed to rotate.

  Further, in the event of a vehicle accident or the like, the third party applies a predetermined force to the handle grip 11 to break the break portion 50a of the stopper 50 and switch the rotation restricting portion 55 from the engaged state to the non-engaged state. When the vehicle receives an impact of a predetermined value or more, the lock mechanism 2b is in an unlocked state. Therefore, the handle grip 11 that is allowed to rotate is rotated to open the door 8 by the mechanical operating unit 3.

<Operational effects obtained in this embodiment>
According to this embodiment, the following effects can be obtained.

  (1) When the fixed portion 21 and the handle grip 11 are engaged with each other by the rotation restricting portion 55, the handle grip 11 cannot be rotated, and the mechanical latch mechanism 2a by the mechanical operating portion 3 is disabled. Cannot be operated. Therefore, when the operation of the electric latch mechanism 2a by the electric operation section 4 based on the operation of the opening operation switch 11a is validated in the engaged state between the fixing portion 21 and the handle grip 11, the latch mechanism 2a is operated. Since the gripping portion does not rotate when the opening operation switch 11a is operated, a high operational feeling can be imparted. And since the rotation control part 55 can be switched from the vehicle outer side to the engaged state, the handlebar grip 11 can be opened from the vehicle outer side when the electric power supply is cut off and the door 8 cannot be opened by the electric operating part 4. Can be opened and the door 8 can be opened by mechanical connection.

  (2) By providing the stopper 50 interlocking with the rotation of the key cylinder 22, the engaged state between the stopper 50 and the engaged portion 51 can be released only by using a mechanical key. Release can be suppressed. Further, when the power supply is cut off and the door cannot be opened by the opening operation switch 11a, when the lock mechanism 2b is in the locked state, the engagement state of the rotation restricting portion 55 is released and the lock mechanism 2b is released. The locked state can be released at the same time, improving operability.

  (3) Since the broken portion 50a is provided, the door 8 can be opened by breaking the broken portion 50a of the stopper 50 by turning the handle grip 11 by applying a force of a predetermined value or more. Therefore, it becomes more effective during emergency response.

  (4) Since the rotation of the handle grip 11 is always inhibited during normal operation, the handle grip 11 is rotated by inertia when an impact is applied to the periphery of the handle grip 11 due to a side collision or the like. Opening of the door 8 is suppressed. Therefore, it is necessary to provide a counterweight that causes the handlebar grip 11 to generate an inertial force in a direction opposite to the inertial force generated in the handlebar grip 11 due to the impact acceleration at the time of a side collision as described in JP 2000-145211, for example. Disappear. Here, since the counterweight is heavy, it is inefficient to set it only for the mechanical operating unit 3 that is used as an auxiliary in an emergency. Therefore, in the above configuration, the outer side handle 10 can be efficiently reduced in weight.

  (5) When the lock state of the lock mechanism 2b is switched to the unlocked state by the electrical operating unit 4, the key cylinder 22 is not interlocked and does not rotate in the unlocking direction. Therefore, it is possible to give priority to the opening operation of the door 8 by the electric operation unit 4 at normal times.
