In the present embodiment, only the assisted standing apparatus 100 on the right foot side will be described in detail. Since the left auxiliary standing device 100 and the right auxiliary standing device 100 have the same structure and are in mirror symmetry, they are not described in detail in this embodiment.

The foot pedal 10 is matched with the shape of the foot of a human body, and can be made of metal or plastic products.

The lower leg support plate 20 includes: a fixed plate 21, a sliding plate 22 and a clip (not shown).

The fixing plate 21 is vertically disposed at the rear of the footboard 10, and the fixing plate 21 has an arc shape and is wrapped around the edge of the rear portion of the footboard 10, thereby forming a chamber for receiving the lower leg of the user. The fixing plate 21 is provided with two sliding grooves extending in the vertical direction at the arc-shaped edge.

The sliding plate 22 is arc-shaped, and the fixed plate 21 is coaxial and has the same radian. The sliding plate 22 is disposed in the sliding groove of the fixed plate 21. When the sliding plate 22 slides to the highest point of the chute, the top of the sliding plate 22 is higher than the top of the fixed plate 21.

The catch is used to fix the slide plate 22 to the fixed plate 21 after the slide plate 22 is slid to a desired position.

A thigh support plate 30 is mounted on the top end of the sliding plate 22 for rotation by the drive mechanism 40 to push the user's thighs and assist the user in standing. The thigh support plate 30 is at a minimum 110 to the calf support plate 20 during rotation to prevent injury to the user's joint during rotation.

The drive mechanism includes: a high-torque steering engine 41, a single-chip microcomputer (not shown in the figure) and a power supply (not shown in the figure).

The large torque steering engine 41 is installed at a connection position between the thigh support plate 30 and the sliding plate 22, and is used for driving the thigh support plate 30 to rotate, and a circuit diagram of the large torque steering engine 41 used in the embodiment is shown in fig. 3.

The single chip microcomputer is arranged in the auxiliary rod 50 and used for controlling the operation of the large-torque steering engine 41.

The power supply is arranged in the auxiliary rod 50 and used for supplying power to the large-torque steering engine 41 and the single chip microcomputer. In this embodiment, the power source is a battery.

The auxiliary lever 50 includes a holding lever 51 and a grip lever 52. The rest bar 51 is vertically provided on the outer side (i.e., the instep side) of the footrest 10. The handrail 51 is in an elliptic cylinder shape, and the upper surface is in an elliptic shape. The holding rod 52 is arranged on the outer surface of the holding rod 51 in a way of being perpendicular to the holding rod, and the holding rod 52 is cylindrical. In this embodiment, the holding rod 51 and the holding rod 52 are made of nontoxic PVC polymer material.

The switch 60 is disposed on the grip 51. The user can adjust the rotation angle of the high-torque steering engine 41 through the switch 60 to help the user stand up.

The use mode of the auxiliary standing device 100 provided by the embodiment is as follows: the user's foot steps on the foot pedal 10. The user presses the heel against the lower leg support plate 20, adjusts the height of the slide plate 22 to a proper position, and fixes the slide plate 22 to the fixed plate 21 using a clip. The user sends a signal to the single chip microcomputer through the switch 60, the single chip microcomputer controls the large-torque steering engine 41 to rotate the thigh supporting plate 30, and the thigh supporting plate 30 provides an upward acting force for thighs of the user to help the user stand.
