Abstract
Description
Technical Field
[0001] This utility model belongs to the field of exoskeletons, specifically relating to a novel modular passive lumbar exoskeleton. Background Technology
[0002] The passive lumbar exoskeleton is a wearable device focused on assisting the movement of the human lumbar spine. It is specifically designed to relieve the burden on the lumbar muscles and reduce the risk of lumbar muscle strain, making it particularly suitable for industrial and logistics work scenarios that require frequent bending and lifting of heavy objects. The passive lumbar exoskeleton achieves passive assistance through a purely mechanical structure, eliminating the need for external power sources such as electricity, air pressure, or hydraulic pressure. This effectively avoids the pain points of traditional active lumbar assist devices, such as large weight, complex systems, high costs, and dependence on power sources, while also ensuring flexibility and wide applicability.
[0003] However, the existing passive lumbar exoskeleton structure has the following drawbacks:
[0004] Commonly used bearing frames and spring housings have limited rotation angles, which can easily cause pulling during large leg movements (such as obstacle crossing and squatting); the fixing straps need to be tightened to ensure synchronization, and long-term wear can easily compress the body, while loosening them can lead to equipment displacement and assist failure, and there is no cushioning or adaptive adjustment design.
[0005] The springs and steel wires used in exoskeletons are prone to fatigue under long-term stress. In addition, the design of bending springs to store energy in some exoskeletons is not very useful when the bending range is small, but it will affect the human body's bending when the bending range is large.
