Abstract
A lock device locks a lid, which protects the inlet, and a power supplying plug. The lock device includes a helical gear rotated by the motor. A helical gear is connected to a control shaft. The control shaft is moved to a hook lock bar lock position when the helical gear rotates counterclockwise from the reference position. The helical gear is connected by a transmission member to a lid lock bar. The lid lock bar is constantly urged toward a lid lock position by a coil spring. When the helical gear rotates clockwise from the reference position, the lid lock bar moves to the lid unlock position against the urging force of the coil spring.
Claims9
A lock device that locks a lid and a power supplying plug, wherein the lid protects a power reception connector, the lock device comprising:
- a plug restriction member that moves between a plug lock position and a plug unlock position, wherein the plug restriction member restricts removal of the power supplying plug from the power reception connector at the plug lock position, and the plug restriction member permits removal of the power supplying plug from the power reception connector at the plug unlock position;
- a lid restriction member that moves between a lid lock position and a lid unlock position, wherein the lid restriction member engages the lid and restricts opening of the lid at the lid lock position, the lid restriction member permits opening of the lid at the lid unlock position, and the lid restriction member is constantly urged toward the lid lock position;
- and
- a drive mechanism including a drive source and a rotating body, wherein the drive source generates drive force and rotates the rotating body in first and second directions from a reference position,
- wherein the drive mechanism is directly or indirectly connected to the plug restriction member to move the plug restriction member from the plug unlock position to the plug lock position when the rotating body rotates from the reference position in the first direction,
- the drive mechanism is directly or indirectly connected to the lid restriction member to move the lid restriction member from the lid lock position to the lid unlock position against an urging force acting on the lid restriction member when the rotating body rotates from the reference position in the second direction,
- when closing the lid with the lid restriction member held at the lid lock position, the lid restriction member engages the closing lid and moves toward the lid unlock position thereby permitting the lid to close, and
- the lid restriction member is formed to be returned to the lid lock position by the urging force at a timing at which the lid reaches a close position.
A lock device mounted on a vehicle, wherein the vehicle includes a battery, a travel motor powered by the battery, a power reception connector for a power supplying plug that charges the battery, and a lid for closing the power reception connector, the lock device comprising:
- a movable stopper pivotally supported by the power reception connector to engage with and disengage from a power supplying plug connected to the power reception connector;
- a rotating body connected to a drive source and rotated by the drive source in first and second directions from a reference position;
- a control shaft coupled to the movable stopper and the rotating body and rotated by the rotating body from a plug unlock position to a plug lock position when the rotating body rotates from the reference position in the first direction, wherein the control shaft is shaped to move the movable stopper to a position at which the movable stopper engages the power supplying plug when the control shaft rotates to the plug lock position;
- and
- a lid lock bar coupled to the rotating body and linearly moved by the rotating body from a lid lock position to a lid unlock position against an urging force acting on the lid restriction member when the rotating body rotates from the reference position in the second direction, wherein
- when the lid is manually operated to close the power reception connector while the lid lock bar is held at the lid lock position, the lid lock bar is urged toward the lid unlock position by the closing lid thereby permitting the lid to close, and
- the lid lock bar is formed to be returned to the lid lock position by the urging force at a timing at which the lid reaches a close position.
