## Abstract

A vehicle charging port locking device has a charging port and a locking mechanism. The charging port has an engaged part that engage an engaging part of a charging connector for supplying power from an external power source to the charging port when in an engaged state. A restraining member is movably mounted between a locked state in which release of the engaged part is restricted by movement of the restraining member in a locking direction to prevent the engaging part from being released from the engaging state, and an unlocked state in which release of the engaging part is permitted by movement of the restraining member in an unlocking direction that is opposite the locking direction. The restraining member can be moved in the unlocking direction by operation of an exposed part that can be operated from beneath the hood of the vehicle.

## Claims

### Claim 1

A charging port locking device comprising:
a charging port having an engaged portion configured to be engaged with an engaging portion of a charging connector by an operation of an operator;
a lock mechanism including a restraining member movably mounted with respect to the charging port between a locking state that restricts release of an engaged state by restricting a releasing operation of the engaging portion due to rotational movement of the restricting member in a locking direction and an unlock state that allows the releasing operation by movement of the restricting member in an unlocking direction that is opposite to the locking direction; and
a cover member covering the lock mechanism from an insertion and removal direction of the charging connector, the cover member having an opening for enabling the engaging portion to be inserted, the cover member has an inner periphery surface that is configured relative to a rotation locus of the restricting member such that a distance between the inner periphery surface of the cover member on a side of the lock mechanism and the rotation locus of the restricting member becomes greater as a distance of the inner periphery surface from the opening increases.

### Claim 2 (depends on 1)

The charging port locking device as claimed in claim 1, wherein
the restricting member is a swing arm that extends radially from a center of rotation.

### Claim 3 (depends on 1)

The charging port locking device as claimed in claim 1, wherein
the restricting member is a rotary plate having a disc-shape with a notch portion and a plate portion.
