Description

A walking aid for human body

technical field

The invention relates to a walker, in particular to a walker for human walking.

Background technique

Walking aids can be divided into active walking aids and passive walking aids from the principle of walking aids. Active walking aids mainly provide assistance to the walking movement of the human body by increasing the external driving force, while passive walking aids do not increase the external driving force. The energy generated during the walking process of the human body is converted, thereby assisting the walking movement of the human body.

Because of the increase of external driving force, active walking aids often add additional control methods to the external drive in advance. When the human body walks, the limbs follow the movement of the walker. Therefore, in the process of walking, it is difficult to realize the human body following the movement for different walking patterns of different people. . Since there is no external driving force in passive walking aid, the auxiliary motion of the walker is generated by the human body's own motion, so the human body can follow the motion.

The current walking aid products are mainly hand-held or exoskeleton, among which most of the hand-held walking aids are passive walking aids, and most of the exoskeletons are active walking aids. Hand-held walking aids are large in size and cannot be hidden and worn; The size of the walker product is large, it cannot be hidden and worn, it is heavy, and the external power configuration battery cannot be used for a long time.

Contents of the invention

The purpose of the present invention is to provide a walking aid for passive walking for the human body to solve the problems that the current walking aid products are large in size, unable to be hidden and worn, heavy in weight, and unable to use the battery for a long time.
