As shown in FIG. 1, the vehicle inlet device 20 is provided at a charging port formed on the rear side surface of the vehicle 10, and a charging connector connected to the charging equipment via a charging cable is connected to the charging equipment from the charging equipment. It is for charging the battery of the vehicle 10 with electric power. The vehicle 10 is configured as an electric vehicle or a hybrid vehicle equipped with a traveling motor and a battery that supplies electric power to the motor.

As shown in FIG. 2, the vehicle inlet device 20 includes a charging lid 21 that opens and closes a charging port, a charging inlet 22 to which a charging connector 100 connected to a charging facility via a charging cable is connected, and a charging inlet 22. The charging connector lock device 30 for locking the charging connector 100 connected to the charging inlet 22 is provided.

A cylindrical insertion-side connection port 101 is provided at the tip of the charging connector 100. By inserting the insertion side connection port 101 of the charging connector 100 into the receiving side connection port 23 of the charging inlet 22, the internal terminal of the charging connector 100 and the internal terminal of the charging inlet 22 are electrically connected.

The upper surface of the charging connector 100 is provided with a lock arm 102 for preventing the charging connector 100 from coming off to the charging inlet 22 when the charging connector 100 is inserted into the charging inlet 22. The central portion of the lock arm 102 has a swing axis (not shown) extending in a direction orthogonal to the longitudinal direction of the lock arm 102. The lock arm 102 is configured to be swingable with the swing shaft as a fulcrum. A torsion spring that urges the lock arm 102 to one side in the swing direction is arranged on the swing shaft of the lock arm 102. An engaging claw 102a projecting downward is provided at the tip of the lock arm 102, and an operation portion 102b pressed by the operator is provided at the base end of the lock arm 102. In the lock arm 102, when the insertion side connection port 101 of the charging connector 100 is inserted into the receiving side connection port 23 of the charging inlet 22, the engaging claw 102a of the lock arm 102 is charged by the urging force of the torsion spring. By engaging with the engaging recess 22a provided in the upper part of the above, the charging connector 100 is prevented from coming off to the charging inlet 22. Further, the lock arm 102 releases the locking of the charging connector 100 from the charging inlet 22 by pressing the operating portion 102b against the urging force of the torsion spring.

The charging connector lock device 30 is a device for locking the charging connector 100 to the charging inlet 22. In this embodiment, the charging connector lock device 30 is a wheel house outer 14 joined to the rear quarter panel 12 of the vehicle 10 and a foil arranged on the vehicle interior side of the wheel house outer 14 as shown in FIG. It is arranged in the space defined by the house inner 16 and the foil house cover 18. As shown in FIGS. 4 and 5, the charging connector lock device 30 includes a lock pin 40, a motor 31, a conversion mechanism 32 that converts the rotational movement of the motor 31 into vertical movement of the lock pin 40, and a release lever 52. And.

The conversion mechanism 32 includes a worm 33 attached to the output shaft of the motor 31, a worm wheel 34 meshed with the worm 33, and a rotating member 35 that rotates integrally with the worm wheel 34. A guide groove 35a that is inclined in the axial direction and the circumferential direction of the rotating member 35 is provided on the side surface of the rotating member 35.

As shown in FIGS. 4 and 5, the lock pin 40 has a shaft portion 41 inserted into an insertion hole 38a formed in the bottom wall of the housing 38 with the tip portion exposed from the housing 38, and a base end of the shaft portion 41. It has a head portion 42 provided in the portion and an engaging projection 43 extending radially (on the left side in the drawing) from the head portion 42. The engaging protrusion 43 is engaged with the guide groove 35a of the rotating member 35. When the rotating member 35 is rotated in one direction by the motor 31 while the engaging claw 102a of the lock arm 102 is engaged with the engaging recess 22a of the charging inlet 22, the engaging protrusion is formed on the upper surface of the guide groove 35a. When the 43 is pushed down, the lock pin 40 is lowered. As a result, the tip of the lock pin 40 presses the upper surface of the lock arm 102 in the direction of pressing the engaging claw 102a against the engaging recess 22a, and locks the charging connector 100 to the charging inlet 22. In the locked state, since the lock arm 102 cannot swing, the operation unit 102b cannot be pressed, and the charging connector 100 cannot be pulled out from the charging inlet 22. On the other hand, when the rotating member 35 is rotated in the other direction by the motor 31, the lock pin 40 is raised by pulling up the engaging projection 43 on the lower surface of the guide groove 35a. As a result, the tip of the lock pin 40 is separated from the lock arm 102. Therefore, by pressing the operation unit 102b, the engaging claw 102a is separated from the engaging recess 22a, and the charging connector 100 is pulled out from the charging inlet 22. It becomes possible.

The release lever 52 is for manually releasing the locked state of the charging connector lock device 30, and is attached to a shaft 54 coaxially fixed to the worm wheel 34 as shown in FIGS. 4 and 5. There is. In this embodiment, by operating the release lever 52 from the front side to the back side in the drawing, the rotating member 35 rotates in the other direction, and the lock pin 40 rises accordingly. As a result, even when the motor 31 fails and the charging connector lock device 30 cannot release the locked state of the charging connector 100, the locked state of the charging connector 100 can be forcibly released by manual operation. Here, in this embodiment, the release lever 52 and the shaft 54 correspond to the lock release mechanism 50.

As shown in FIG. 6, the release lever 52 is operated by using a rod-shaped tool 200 having a pressing portion 201 at the tip and a grip portion 202 at the base end. In this embodiment, as shown in FIG. 7, an insertion port 19a (entrance portion) for the tool 200 is formed on the deck side 19 (side surface portion) of the luggage space at the rear of the vehicle. Further, an insertion hole 16a into which the tool 200 is inserted is formed in the wheel house inner 16 (inner panel) that separates the luggage space (vehicle interior) and the unlocking mechanism 50. In this embodiment, the insertion hole 16a is formed so as to be located on a straight line connecting the insertion port 19a and the release lever 52 of the lock release mechanism 50. The insertion hole 16a is usually covered with a removable cap (not shown).

To operate the release lever 52 using the tool 200, first, the cap placed on the insertion hole 16a is removed, and then the attachment 60 is attached to the insertion hole 16a as shown in FIG. The attachment 60 is a cylindrical member having an outer diameter slightly smaller than the inner diameter of the insertion hole 16a, and has a protruding piece 62 protruding radially from the outer peripheral surface from one end to the center. The attachment 60 is attached by inserting the attachment 60 into the insertion hole 16a from the other end side and pushing the protrusion piece 62 until it hits the outer peripheral edge of the insertion hole 16a. As a result, the attachment 60 (cylindrical member) is arranged so that its central axis substantially coincides with the straight line connecting the insertion port 19a and the release lever 52 of the lock release mechanism 50.

When the attachment 60 is attached to the insertion port 16a, as shown in FIG. 9, the grip portion 202 of the tool 200 is gripped and the tip portion (pressing portion 201) of the tool 200 is inserted into the insertion port 19a formed on the deck side 19. .. Next, as shown in FIG. 10, the tool 200 is pushed in the extending direction so that the tip end portion of the tool 200 penetrates the inside of the attachment 60 attached to the insertion hole 16a of the foil house inner 16. Subsequently, as shown in FIG. 11, the tool 200 is further pushed through the inside of the attachment 60. As a result, the tip of the tool 200 is attracted toward the release lever 52 by the attachment 60 that extends cylindrically along the straight line connecting the insertion port 19a and the release lever 52, and abuts on the pressed surface 52a. Then, the tool 200 is further pushed in so that the shaft 54 rotates in the unlocking direction (in the direction of the thick arrow in the figure), and the pressed surface 52a of the release lever 52 is pressed by the pressing portion 201 at the tip portion. As a result, the lock state of the charging connector 100 can be forcibly released by operating the release lever 52.

The unlocking structure of the embodiment described above includes the unlocking mechanism 50 arranged outside the vehicle interior with the wheel house inner 16 (inner panel) separated from the vehicle interior, and the insertion port 19a (entrance portion) formed in the vehicle interior. And an insertion hole 16a formed in the wheel house inner 16 and an attachment 60 (cylindrical member) attached to the insertion hole 16a. The insertion hole 16a is formed so as to be located on a straight line connecting the insertion port 19a and the release lever 52 of the lock release mechanism 50. Further, the attachment 60 is attached to the insertion hole 16a so that its central axis substantially coincides with the straight line connecting the insertion port 19a and the release lever 52. The locked state of the charging connector lock device 30 is released by inserting the rod-shaped tool 200 into the insertion port 19a, passing through the inside of the attachment 60, and pressing the charging connector lock device 30 against the release lever 52. As a result, the tip of the tool 200 can be attracted to the release lever 52 by the attachment 60, so that the accessibility when operating the lock release mechanism from the vehicle interior can be further improved.
