Many diseases can cause weakness of lower limbs, amyotrophy and hemiplegia of human body, cause walking disorder, and also often have difficulty in standing and walking unstably for some old and weak people. Currently, disabled persons (particularly those with disabled legs) need to rely on crutches to walk. However, there are some drawbacks to using a crutch to assist walking: the knee car is correspondingly developed because the user feels tired after a long time and the walking speed is very slow; however, the commercial knee-pad car is generally used for supporting the knee, the gravity center of a person is higher when in use, and the potential safety hazard exists due to unstable gravity center when the person moves; in view of this, we improve the structure of the knee car, increase the pedal structure to lower the center of gravity, and improve the safety.
