Abstract:
1. A lower limb stretching workout device, comprising: a frame unit having two guide rails opposing each other; two sliding plates each with two edges having a plurality of rollers slidingly movable along the two guide rails and within a guiding range; a motor assembly for driving a rotating shaft through a transmission module, the motor assembly comprising a motor holder, a motor, and a motor spindle, the motor being fastened to the motor holder, the motor spindle penetrating the motor and protruding from a side of the motor to reach the motor holder, the transmission module comprising first through fourth belt pulleys, first and second belts, and an axle rod, the axle rod being fixed to the motor holder, the first belt pulley being fixed to the motor spindle, the fourth belt pulley being fixed to the rotating shaft, the second and third belt pulleys being fixed to each other, the second and third belt pulleys being pivotally connected to the axle rod, the first belt being wound around the first and second belt pulleys, the second belt being wound around the third and fourth belt pulleys; and the two cranks each having a driving end and an acting end, the driving end being pivotally connected to a cam, and the acting end being pivotally connected to a lug at a bottom surface of each of the two sliding plates, wherein, when the motor assembly drives the transmission module such that the transmission module drives the rotating shaft to rotate, a torque of the rotating shaft is converted by the cams into a push and a pull for driving the two cranks to push and pull the two sliding plates, thereby causing the two sliding plates to slidingly move toward each other and away from each other.
