Problems solved by technology

[0003] Upright walking—a highly evolved performance of human beings can be improved through artificial technology. However, it is very inconvenient to use battery packs or air compression systems to reduce energy consumption because of the following reasons: First, battery packs or The air compression system itself is very heavy. If it is installed on a person, most of the energy will be consumed on the heavy machine, and the effect may be counterproductive.
Second, the battery pack is not environmentally friendly, not recyclable, and the walking distance is limited. It is not suitable for people who walk for a long time, which makes its target group significantly narrowed to smart for rehabilitation.
Third, how will the battery pack and air compression system work for non-cyclic actions, such as when people stand up, turn around, stand up, sit down, etc., they may not achieve the effect of saving energy

Embodiment

[0024] Take a cyclical walking or running movement as an example (the so-called cyclical movement refers to the process of one foot touching the ground for the first time until the same foot touches the ground again), in a cyclical movement, when one foot is in the stance phase, the other Only the pin is in the swing phase. When the swing pin finishes landing and enters the standing phase, the transmission rod 5 is lifted up under the action of gravity, and the universal ball 7 will slide relative to the ground (to prevent people from walking due to device contact with the ground). The ground friction is too large and trips), the spring 4 is pulled under the action of the transmission rod 5, causing the spring to be stretched, and a cycle of action is completed. During this process, the gravitational potential energy is stored and converted into elastic potential energy. When the foot enters the next swing period, the stored elastic potential energy is released. The device bear...

Abstract

The invention relates to the field of sports medical rehabilitation, in particular to a loaded walking aid exoskeleton, comprising an exoskeleton body and also comprising an energy conversion device, an assist buffering device and a fixture. The loaded walking aid exoskeleton is effective in assisting a user with walking difficulty, such as old people, persons with incomplete spinal cord injury or multiple sclerosis, or trekking military personnel; the loaded walking aid exoskeleton is provided to store gravitational potential energy to be consumed by walking in the form of elastic potential energy so as to assist in converting the elastic potential energy into biological energy during next action, and walking is easier and takes less effort.

Description

technical field [0001] The invention relates to the field of sports medical rehabilitation, in particular to a weight-bearing walking exoskeleton. Background technique [0002] Now exoskeleton research is in the limelight. People hope to transform human beings into robots, which can improve athletic ability without increasing the load, and can "fly over the wall". At present, most exoskeletons need to rely on motors and battery packs as power sources, and some use air compression systems to reduce energy consumption for human walking. [0003] Upright walking—the highly evolved performance of human beings can be improved through artificial technology. However, it is very inconvenient to use battery packs or air compression systems to reduce energy consumption because of the following reasons: First, battery packs or But the air compression system itself is very heavy. If it is installed on a person, most of the energy will be consumed on the heavy machine, and the effect ma...
