Resilient power device

A resilient power device adapted to drive a transmission rod of a vehicle, which extends along a first axis, said resilient power device comprising:

• a housing adapted for the transmission rod to extend rotatably thereinto;
• a rotary shaft adapted to extend and be spaced apart from the transmission rod along the first axis;
• a power release unit including a first rod and a second rod that are mounted rotatably in said housing, that extend and are spaced apart from each other along a second axis parallel to the first axis, that are spaced apart from said rotary shaft, and that are adapted to be aligned respectively with the transmission rod and said rotary shaft in a direction perpendicular to the first and second axes;
• a power storage clutch adapted to be connected between the transmission rod and said rotary shaft, so as to allow for connection and disconnection between the transmission rod and said rotary shaft;
• a power release clutch connected between said first and second rods, so as to allow for connection and disconnection between said first and second rods;
• a first gear unit mounted to said first rod and the transmission rod such that, rotation is transferred between said first rod and the transmission rod;
• a second gear unit mounted to said rotary shaft and said second rod such that, rotation is transferred between said rotary shaft and said second rod;
• and
• at least one resilient member connected between said housing and said rotary shaft;
• wherein said resilient power device is transformable between a power storage state and a power release state such that, when said resilient power device is in the power storage state, the transmission rod and said rotary shaft are interconnected by said power storage clutch, and said first and second rods are disconnected from each other by said power release clutch, so as to allow the transmission rod and said rotary shaft to rotate in a first rotational direction, thereby deforming said at least one resilient member to store an elastic potential energy, and when said resilient power device is transformed to the power release state, the transmission rod and said rotary shaft are disconnected from each other by said power storage clutch, and said first and second rods are interconnected by said power release clutch, so as to allow said rotary shaft to rotate in a second rotational direction, which is opposite to the first rotational direction, so as to return said at least one resilient member to its original shape, thereby releasing the elastic potential energy, after which the transmission rod is rotated in the first rotational direction by said second gear unit, said power release unit and said first gear unit.
