The charging connector locking device 30 locks the charging connector 100 connected to the charging inlet 22.

At the tip of the charging connector 100, a cylindrical insertion side connection port 101 is provided. By inserting the insertion-side connection port 101 of the charging connector 100 into the reception-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.

A lock arm 102 is provided on the upper surface of the charging connector 100 to prevent the charging connector 100 from coming off the charging inlet 22 when the charging connector 100 is inserted into the charging inlet 22. At the center of the lock arm 102, there is a swing shaft (not shown) extending in a direction orthogonal to the longitudinal direction of the lock arm 102. The lock arm 102 is swingable around a swing shaft. 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 that projects downward is provided at the tip of the lock arm 102, and an operating portion 102b that is pressed by an operator is provided at the base end of the lock arm 102. When the insertion side connection port 101 of the charging connector 100 is inserted into the reception side connection port 23 of the charging inlet 22, the lock arm 102 has the engaging claw 102 a of the lock arm 102 which is biased by the biasing force of the torsion spring. The charging connector 100 is prevented from coming off from the charging inlet 22 by engaging with the engaging concave portion 22a provided on the upper part of the. Further, the lock arm 102 releases the retainer of the charging connector 100 from the charging inlet 22 when the operating portion 102b is pressed against the biasing 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 the present embodiment, the charging connector locking device 30 is, as shown in FIG. 3, a wheel house outer 14 joined to a rear quarter panel 12 of the vehicle 10, and a wheel arranged inside the wheel house outer 14 than the wheel house outer 14. It is arranged in a space defined by the house inner 16 and the wheel 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 for converting 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 rotary member 35 that integrally rotates coaxially with the worm wheel 34. On the side surface of the rotating member 35, a guide groove 35a that is inclined with respect to the axial direction and the circumferential direction of the rotating member 35 is provided.

As shown in FIGS. 4 and 5, the lock pin 40 has a shaft portion 41 that is inserted into an insertion hole 38 a formed in the bottom wall of the shaft portion 41 in a state where the tip portion is exposed from the housing 38, and a base end of the shaft portion 41. A head portion 42 provided on the portion, and an engagement protrusion 43 extending from the head portion 42 in the radial direction (left side in the drawing). The engagement protrusion 43 is engaged with the guide groove 35 a of the rotating member 35. When the rotation member 35 is rotated in one direction by the motor 31 with the engagement claw 102a of the lock arm 102 engaged with the engagement recess 22a of the charging inlet 22, the engagement protrusion is formed on the upper surface of the guide groove 35a. The lock pin 40 is lowered by pushing down 43. As a result, the tip of the lock pin 40 presses the upper surface of the lock arm 102 in the direction in which the engagement claw 102a is pressed against the engagement recess 22a, and the charging connector 100 is locked to the charging inlet 22. In the locked state, since the lock arm 102 cannot swing, the operation portion 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 engagement pin 43 is pulled up on the lower surface of the guide groove 35a, and the lock pin 40 is moved up. As a result, the tip end of the lock pin 40 is separated from the lock arm 102, and thus the operation claw 102a is separated from the engagement recess 22a by pushing down the operation part 102b, and the charging connector 100 is pulled out from the charging inlet 22. It becomes possible.

The release lever 52 is for releasing the locked state of the charging connector lock device 30 by a manual operation, 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. Accordingly, even when the motor 31 fails and the charging connector locking device 30 cannot release the locking state of the charging connector 100, the charging connector 100 can be forcibly released by the 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 using a rod-shaped tool 200 having a pressing portion 201 at the tip and a grip portion 202 at the base. In this embodiment, as shown in FIG. 7, an insertion opening 19a (entrance) of the tool 200 is formed on the deck side 19 (side surface) of the luggage space at the rear of the vehicle. The wheel house inner 16 (inner panel) separating the luggage space (vehicle compartment) and the lock release mechanism 50 is provided with an insertion hole 16a into which the tool 200 is inserted. In the present 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 that covers 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 radially protruding 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 it in until the protruding piece 62 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 opening 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 opening 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 of the tool 200 penetrates the inside of the attachment 60 attached to the insertion hole 16a of the wheel house inner 16. Then, as shown in FIG. 11, the tool 200 is penetrated through the inside of the attachment 60 and further pushed. As a result, the tip end of the tool 200 is guided toward the release lever 52 by the attachment 60 extending in a cylindrical shape along the straight line connecting the insertion port 19a and the release lever 52, and abuts against the pressed surface 52a. Then, the tool 200 is further pushed so that the shaft 54 rotates in the unlocking direction (the direction of the thick line arrow in the figure), and the pushing portion 201 at the tip portion pushes the pushed surface 52a of the release lever 52. This allows the release lever 52 to be operated to forcibly release the locked state of the charging connector 100.

The lock release structure of the above-described embodiment has the lock release mechanism 50 arranged outside the vehicle compartment 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 lock state of the charging connector lock device 30 is released by inserting the rod-shaped tool 200 into the insertion port 19a and abutting and pressing the release lever 52 through the inside of the attachment 60. As a result, the tip of the tool 200 can be guided 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.
