[0039] A hydraulic driving member 7, used for driving the output end of the oil cylinder 5 to extend or retract;

[0040] At least one motor 8 is used to drive one of the moving wheels 6 .

[0041] Furthermore, in the present embodiment, the base 1 is arranged horizontally, and a moving wheel 6 is provided at each of its four corners. A push handle 9 is vertically provided on one side of the base 1, and the two moving wheels 6 adjacent to the push handle 9 are guide wheels for controlling the travel direction of the lifting platform 3 vehicle. Each of the two moving wheels 6 away from the push handle 9 is provided with a motor 8, which is fixedly mounted at the bottom of the base 1, and the output shaft of the motor 8 is the motor 8 shaft. A gear is installed on the motor 8 shaft, and the gear is meshed with a transmission gear 12, and the transmission gear 12 is meshed with the gear portion on the moving wheel 6. The transmission gear 12 is used to transmit the torque output by the motor 8 shaft to the moving wheel 6, thereby driving the moving wheel 6 to rotate relative to the ground, thereby realizing the automatic movement of the base 1.

[0042] Furthermore, in this embodiment, the lifting mechanism 2 includes an outer frame 21 and an inner frame 22, and the inner frame 22 and the outer frame 21 are scissor-shaped. That is, the inner frame 22 and the outer frame are distributed in an X shape, and the midpoints of the two are connected by a hinge shaft. The inner frame 22 is located on the inner side of the outer frame 21, and the lower end of the inner frame 22 is hinged to the base 1, and the upper end is slidably matched with the guide rail at the bottom of the platform 3 through an upper pulley. The lower end of the outer frame 21 is slidably matched with the guide rail at the bottom of the base 1 through a lower pulley, and the upper end is hinged to the bottom of the platform 3.

[0043] Furthermore, both sides of the inner frame 22 are provided with limiting side plates 17, and the base 1 is provided with limiting screws 16 at positions corresponding to the limiting side plates 17. The limiting screws 16 are threadedly mounted on the base 1, and the heads of the limiting screws 16 are exposed on the surface of the base 1. The thickness of the limiting side plates 17 is less than the thickness of the outer frame 21, so as to avoid interference between the limiting side plates 17 and the guide rails on the base 1. When the platform 3 is at the lowest position, the lower edge of the limiting side plates 17 abuts against the head of the limiting screws 16, so as to avoid direct contact between the edge of one side of the inner frame 22 and the base 1.

When the lifting knob 14 is rotated counterclockwise to the initial position, the hydraulic drive 7 stops working, and the platform 3 remains at a predetermined height. Manually drive the pedal rod 4 to swing, the pedal rod 4 continues to pump hydraulic oil into the oil cylinder 5, and the platform 3 continues to rise. That is, the pedal rod 4 is used to manually control the oil cylinder 5, and the hydraulic drive 7 is used to automatically control the oil cylinder 5, and both can control the extension of the piston rod at the same time. Toggle the handle 13, the handle 13 is connected to the oil drain valve 51 of the oil cylinder 5, so that the oil drain valve 51 is switched from a closed state to an open state, the oil cylinder 5 releases pressure and drains oil, the piston rod gradually retracts, the lifting mechanism 2 descends, and the platform 3 gradually decreases in height.

[0047] The travel knob 15 is rotated clockwise, and the motor 8 drives the moving wheel 6 to move forward. When the travel knob 15 is rotated counterclockwise to the initial position, the motor 8 stops working. The travel knob 15 is rotated counterclockwise continuously, and the motor 8 shaft rotates in the opposite direction to drive the moving wheel 6 to move backward.
