This disclosure describes manual release systems for electrified vehicle charge port locks. In some embodiments, a vehicle key may be used to manually override a position of the charge port lock. In other embodiments, a pull button and cable arrangement may be used to manually override the position of the charge port lock. The pull button may be packaged under a vehicle hood and, in some embodiments, may be mounted to either a cooling system component or a grille support structure.

An actuation assembly for a refueling port or charging port flip cover assembly is rotatably mounted on a base and includes a locking means, a flip cover rotating shaft, a transmission gear, a drive gear and a drive member. The locking means is movably disposed on the base and configured to lock or release a flip cover. The flip cover rotating shaft is configured to rotate the flip cover and includes a fitting portion. The transmission gear includes a receiving portion and is installed around the fitting portion. The drive gear and the drive member are configured to synchronously rotate. The drive gear is meshed with the transmission gear and the drive member is configured to drive the locking means. In moving the locking means from a release position to a locking position, the drive gear blocks the rotation of the transmission gear and prevents the flip cover from opening.

A flip cover actuation assembly for actuating a flip cover is movably mounted on a base. The flip cover actuation assembly has a locking means, a hinge means, a drive shaft and a drive member. The drive shaft has a fitting portion. The hinge means is installed around the fitting portion. An engagement structure is provided on a receiving portion of the hinge means. The engagement structure enables the receiving portion and the fitting portion to rotatably engage or separate such that the drive shaft moves the flip cover relative to the hinge means. The locking or releasing of the flip cover and the opening and closing of the flip cover is achieved by the drive shaft with the drive member. In addition, the releasing and the opening of the flip cover are achieved at different times to avoid any interferences.

In the lid opening and closing device, the rotating body at the initial position rotates to one side in the rotation direction, so that the lock member is disengaged from the first link. Further, the first link and the rotating body are provided with a differential connecting mechanism, and the differential connecting mechanism connects the rotating body and the first link to operate the link mechanism at the retracted position after the lock member is disengaged from the first link, when the rotating body is rotating. As a result, the differential connecting mechanism imparts a time difference between the two operations of the rotating body. Therefore, the lock member and the link mechanism can be operated by rotationally driving the rotating body by a single actuator.

In a lid opening and closing device for vehicle, a rod can move forward and backward between pushed-in and protruding positions, and is supported on a case so that the rod can attain a lid closed position where the rod returns from pushed-in position toward protruding position only by predetermined movement amount. An axial position-restricting groove has a pin-receiving portion and is formed on the rod or a coupling member. An elastic member has a pin inserted into the groove while being receivable by the portion when the rod is at lid closed position, the elastic member being supported on the case and exhibiting resilient force making the pin resiliently abut against the rod or coupling member. The case is provided with a restricting part capable of abutting against the elastic member, and restricting displacement of the elastic member to a side where the pin is disengaged from the groove.

A cover assembly for a charging port of an electric machine includes a head plate, a non-metallic base plate, and a flexible membrane. The head plate extends across an opening of an outer panel assembly of the machine to define an aperture. The non-metallic base plate is movable with respect to the head plate to selectively open and close the aperture. The flexible membrane is fixedly coupled to the head plate and slidably engaged to the non-metallic base plate to enable the non-metallic base plate to slide with respect to the head plate and move between a folded state and an unfolded state with respect to the head plate. In the unfolded state, the non-metallic base plate closes the aperture, and, in the folded state, the non-metallic base plate opens the aperture to allow access to the charging port from an outside through the aperture.
