Detailed Description

The invention will be further described with reference to the accompanying drawings:

in the drawings of the present application: the safety seat comprises a gear mechanism 1, a plane four-bar mechanism 2, a control panel 3, a gear motor 4, a rotary armrest 5, a chassis support 6, wheels 7, a wheel motor 8, a folding pedal 9 and a telescopic safety belt 10.

Example 1

As shown in fig. 1-2, the device of the present invention is composed of a chassis part, an auxiliary force arm and a control device. Wherein the chassis part comprises a chassis bracket 6, wheels 7 and a wheel motor 8. Four wheels 7 are fixed on the chassis bracket 6, and a wheel motor 8 is arranged beside each wheel 7. A foldable pedal 9 is fixedly arranged on the chassis bracket 6 through a hinge, and when the foldable pedal 9 is unfolded and placed parallel to the ground, a user can stand on the foldable pedal to move along with the device; after the foldable pedal 9 is rotated by 90 degrees and folded, a user can stand on the ground to carry out walking rehabilitation training. The auxiliary force arm comprises a gear mechanism 1, a planar four-bar linkage mechanism 2, a control panel 3, a gear motor 4 and a rotary handrail 5. The rotary armrest 5 is also provided with a telescopic safety belt 10, and the telescopic safety belt 10 can be tied to the waist and the hip of a user to play a role in protection and force assistance.
