Lower limb rehabilitation training elliptical machine device

The invention provides a lower limb rehabilitation training elliptical machine device which comprises a device rack, a driving transmission unit, an elliptical trajectory implementation unit and pedal plate connecting units, wherein the device rack comprises an arm-rest frame, a base and vertical plates; the driving transmission unit mainly comprises a drive motor, a small belt wheel, a big belt wheel and a synchronous belt; the elliptical trajectory implementation unit comprises a rotating disc, an elliptical sliding groove, a sliding block, a linear sliding rail and a group of guide wheels; the pedal plate connecting units comprise connecting pieces, pedal plates, flange plates and a bearing. According to the lower limb rehabilitation training elliptical machine device, provided by the invention, a patient is driven to be rehabilitated along the elliptical trajectory, which is more aligned with normal gait of people; besides, as the synchronous belt is in transmission connection with the linear guide rail, and the sliding block is matched with the elliptical sliding groove, the lower limbs can perform rehabilitation training along the elliptical trajectory, the machine device is compact in structure, the mechanism that forms the elliptical trajectory is driven in a single degree-of-freedom manner, and a better lower limb rehabilitation training effect is achieved.
