Dual-mode self-contained walking assist device

Abstract

The invention provides a dual-mode self-contained walking assist device. An upper segment rod is connected with a lower segment rod through a knee set, the lower segment rod is connected with a sub rod through an adjusting strut, the sub rod is connected with a baseplate through an ankle set, and the leg and the foot of a user are tightened through a tightening belt; the knee set and the ankle set each comprises a stacking core, a piston rod, a return spring and a hole misplacing spring, the stacking core is meshed with the hole misplacing spring under the action of the piston rod, and the stacking core breaks away from the hole misplacing spring of the knee set by being driven by the return spring; a hydraulic gain mechanism is installed between the upper segment rod and the lower segment rod; an air bag is installed on the front portion of the baseplate, a hollow bubble is installed in a trigger on the rear portion of the baseplate, liquid is filled into the space between the trigger and the hollow bubble and used for driving the piston rods and the hydraulic gain mechanism, and the hollow bubble is communicated with the air bag. The dual-mode self-contained walking assist device is mainly used for a person to walk in mountain areas, a power supply is not needed, and the degree of fatigue of the user can be alleviated simply and conveniently with the low cost.

Description

technical field [0001] The invention belongs to the technical field of human body assisted walking, and mainly relates to a booster device, in particular to a device that generates hydraulic force by gravity and reduces the load on lower limbs through staggered hole springs. Background technique [0002] Existing walking assist devices (human body exoskeleton technology) are all powered by a series of complex sensors and servo mechanisms to provide assistance to people's walking, with loads ranging from tens of kilograms to hundreds of kilograms. Research on exoskeleton technology in the United States began in the 1960s and began to expand on a large scale in the 1990s. In 2000, the U.S. Defense Advanced Research Projects Agency invested $75 million to launch the "Exoskeleton Combat Concept for Enhanced Human Function" (EHPA) program to carry out research on exoskeleton technology through a competitive model. [0003] In the competition with the "Berkeley" lower extremity e...
