Portable flexible walking assisting equipment
The invention discloses portable flexible walking assisting equipment. The portable flexible walking assisting equipment comprises knee joint flexible actuating mechanisms (1), air pressure forming mechanisms (2), flexible fixing bands (3) and air pipes (4). In the walking process of a person, the air pressure forming mechanisms (2) make the air pressure of air bags of the knee joint flexible actuating mechanisms (1) rapidly increased or decreased, and the knee joint flexible actuating mechanisms (1) generate torque assisting the knees in bending and stretching. The weight of the person is adopted as the driving force of the equipment, and no other additional energy is needed; the flexible driving mode combining the pneumatic driving force of the air bags and the elastic force of torsion springs is adopted for the actuating parts, and the pneumatic driving force and the elastic force compensate for each other in the walking process of the person. By adopting the flexible driving mode combining the pneumatic driving force and the elastic force of the torsion springs, the structural inertia is small, the defects that a rigid mechanism like a common leg assistance device or an exoskeleton robot is large in inertia, likely to injure the knee joints of a person, poor in comfort and the like are overcome, and the safety and comfort of the equipment are improved.
