Abstract
The utility model relates to a power-driven double arm brace which comprises a lead screw, a motor connected with the lead screw in a transmission mode, a transverse beam matched with the lead screw in a screw-thread fit mode, a pair of supporting rods fixedly connected with two ends of the transverse beam, and arm brace rods connected with the bottom ends of the supporting rods in a hinged mode. A mesh gear extending outward is arranged on the outer lateral side of the top end of each arm brace rod. A mesh seat is fixed on the outer lateral sides of every two adjacent mesh gears. When the power-driven double arm brace is used, the lead screw is controlled to rotate by controlling the motor, and then the supporting rods are controlled to synchronously move up and down by controlling the transverse beam. When the supporting rods synchronously move downwards, the arm brace rods swing downwards in place under the matching action of the mesh seats and the mesh gears and are in a splayed shape. Then the supporting rods continue to move downwards until the supporting rods contact with the ground and then lift the rear end portion of an electric vehicle or a motorcycle, and the vehicle is fixed. Due to the fact that the whole process can be achieved in an electric control mode, manual work is not needed, and a user can use the arm brace conveniently. When the electric vehicle or the motorcycle is needed by the user, the user just needs to control the motor to move in the opposite direction, and then the arm brace can be folded automatically.
