A vehicle includes an image acquisition unit, a cap provided on a body of the vehicle and configured to open and close a replenishing port for replenishing an energy source, a driving unit allowing the cap to be separated or connected from/to the body, and a controller configured to determine an intention of a user to replenish the energy source on the basis of an image acquired by the image acquisition unit, and control the driving unit such that the cap is automatically separated from the body in response to determining that the intention of the user to replenish the energy source exists.

A lid opening/closing device includes: a base member provided with an opening; a lid configured to open/close the opening; and a positioning portion configured to position at least a vertical position of the lid relative to the base member at a closed position of the lid. The positioning portion includes an engagement recess portion provided to the base member in a recess shape, and an engagement projection portion provided to the lid in a projection shape and configured to be engaged with the engagement recess portion at least in an up-down direction at the closed position of the lid. The engagement recess portion includes a rib extending in the up-down direction at the closed position of the lid. The rib is engaged at a distal end thereof with the engagement projection portion at the closed position of the lid.

The present application provides a cover assembly comprising a housing, a cover and a cover pusher. The housing has a housing opening and has a height direction and a depth direction. The housing defines a first track groove. The cover is coupled to the housing through the first track groove and is configured to move along the height direction and the depth direction between a closed position and an open position under the guidance of the first track groove to close or open the housing opening. The cover pusher is provided with an operation structure and is operatively connected to the cover through the operation structure to push the cover to move between the closed position and the open position under the drive of a drive device. The first track groove comprises a first limit groove segment configured to prevent the cover from moving along the height direction of the housing under an external force when the cover is in the closed position. The operation structure is configured to prevent the cover from moving along the depth direction of the housing under an external force when the cover is in the closed position.

A lid opening and closing device includes a lid plate. The lid plate covers an opening portion. A switch is disposed in the opening portion. The switch performs an opening and closing drive of the lid plate. A through-hole is perforated in the lid plate at a portion facing the switch. Further, a cap is provided on the lid plate. The cap is movable forward and backward inside the through-hole in a penetration direction.
