Abstract
A vehicle shutter device includes first and second flaps, one actuator, and a link mechanism. The link mechanism includes a connecting rod that couples the flaps to each other such that the flaps rotate in synchronization with each other. The shutter device is provided with stoppers configured to prohibit each of the flaps from being displaced beyond a normal opening and closing range when the link mechanism is in a normal state. When coupling between the connecting rod and the first flap is released in the first pivotally attaching portion in a state where coupling between the connecting rod and the second flap is maintained in the second pivotally attaching portion, the actuator is allowed to rotate beyond a normal rotation range of the actuator corresponding to the normal opening and closing ranges of the first and second flaps.
Claims4
A vehicle shutter device comprising:
- a support frame;
- a first flap attached to the support frame so as to be rotatable about a first rotation axis;
- a second flap attached to the support frame so as to be rotatable about a second rotation axis parallel to the first rotation axis;
- one actuator configured to generate a driving force for rotating the first flap and the second flap;
- a link mechanism configured to transmit the driving force generated by the actuator to the first flap and the second flap, the link mechanism including a connecting rod that couples the first flap and the second flap to each other such that the first flap and the second flap rotate in synchronization with each other, a first pivotally attaching portion of the connecting rod being pivotally attached to the first flap, a second pivotally attaching portion being pivotally attached to the second flap;
- and
- a stopper configured to, when the link mechanism is in a normal state, prohibit each of the first flap and the second flap from being displaced beyond a normal opening and closing range between a fully open position and a fully closed position,
- wherein the link mechanism is configured such that when coupling between the connecting rod and the first flap is released in the first pivotally attaching portion in a state where coupling between the connecting rod and the second flap is maintained in the second pivotally attaching portion, the actuator is allowed to rotate beyond a normal rotation range corresponding to the normal opening and closing ranges of the first flap and the second flap.
