Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent assistance for the disabled, and specifically relates to an exoskeleton robot telescopic adjustment device. Background Art

[0002] The exoskeleton consists of two robotic legs that are mounted on a person's legs to help the person's legs move in a balanced manner. The device is designed to help the elderly and those with disabilities who may have nerve or muscle damage and difficulty walking, thereby preventing them from falling or getting injured due to movement. With the increasing proportion of the aging population, it is important for the elderly and people with physical disabilities to be able to walk normally like ordinary people.

[0003] Currently, most products on the market use aluminum alloy as the frame. In order to match people of different heights and leg lengths, installation holes are punched in the aluminum alloy to achieve telescopic movement. Aluminum alloy itself is heavy, and under certain strength requirements, the thickness of the aluminum alloy must be increased. When worn by different groups of people, the telescopic mechanism installed by punching holes sometimes has a poor match, resulting in discomfort after wearing, which seriously affects the customer experience.
