Problems solved by technology

[0002] At present, joint assist technology is more and more widely used in human rehabilitation, industry, construction, fire protection and other fields. The power drive of joint assist technology usually realizes functions through DC servo motors, hydraulic pressure, air pressure, flexible cables, etc., but the equipment itself Too heavy (generally more than 20KG), due to the heavy equipment, the power provided by the battery is generally only enough to use for about 2 hours; the equipment structure is complex, it is easy to interfere with the wearer's own activities; the bulky size limits the wide range of application environments Sex; high cost of equipment, can not be applied to the mass population

Abstract

The present invention provides a distributed drive variable stiffness joint booster mechanism, which includes: a shape memory polymer; a heating device, which is attached to the surface of the shape memory polymer in the longitudinal direction; a temperature sensor, which is pasted on the heating device. The surface of the device; the hinge layer, which is pasted on the upper and lower surfaces of the shape memory polymer; the cover layer, which is pasted on the surface of the hinge layer opposite to the shape memory polymer; elastic breathable fabric, It houses the cover layer, the hinge layer, the temperature sensor, the heating device, and the shape memory polymer next to the cover layer. The use of shape memory polymers to drive the variable stiffness joint booster mechanism can change the problem of a single drive source for the booster, and develop the booster into a distributed drive. The drive of each joint is more accurate and the degree of mutual interference is smaller, making the equipment lighter and more efficient. The effect of prolonged working hours.

Description

technical field [0001] The invention relates to a booster mechanism, in particular to a distributed drive variable stiffness joint booster mechanism. Background technique [0002] At present, joint assist technology is more and more widely used in human rehabilitation, industry, construction, fire protection and other fields. The power drive of joint assist technology usually realizes functions through DC servo motors, hydraulic pressure, air pressure, flexible cables, etc., but the equipment itself Too heavy (generally more than 20KG), due to the heavy equipment, the power provided by the battery is generally only enough to use for about 2 hours; the equipment structure is complex, it is easy to interfere with the wearer's own activities; the bulky size limits the wide range of application environments Sex; equipment cost is high, can not be applied to popular crowd. Contents of the invention [0003] According to the technical problem raised above, a distributed drive v...
