Abstract

The invention discloses a wearable hooped pneumatic air inflation bent flexible actuator which comprises a front end cover, a tail end cover, an upper-side corrugated structure, a bottom layer, hoops, ropes and a hose. The front end cover and the tail end cover are located at the two ends of the corrugated structure correspondingly, and the bottom layer is located at the lower end of the corrugated structure. A cavity structure with the interior in a corrugated shape is formed by the front end cover, the tail end cover, the corrugated structure and the bottom layer. Each hoop is of a semicircular structure, and the hoops are arranged at the wave crest positions of the corrugated structure and the outer portion of the bottom layer in a hooping and sleeving manner. The ropes are mounted at the two ends of the lower end of the bottom layer, and the length direction of the ropes is consistent with the axial direction of the corrugated structure. The hose is mounted on the front end cover and communicates with an inner cavity of the corrugated structure. The front end cover, the tail end cover and the corrugated structure are each made of an elastic material. The actuator has good flexibility and is high in pressure bearing capacity, large in tail end output force and especially suitable for the field of medical rehabilitation.

Description

technical field [0001] The invention belongs to the technical field of pneumatics, in particular to a wearable hoop-type pneumatic inflatable bending flexible driver. Background technique [0002] Pneumatic flexible actuator is a new type of driving device gradually developed in recent years. It is driven by air pressure, has good flexibility, and the driving process is stable and safe, so it is especially suitable for medical rehabilitation, pneumatic clamping and other fields. JosephL.McKibben designed the earliest flexible actuator, known as the McKibben type PMA (Pneumatic MuscleActuator), which consists of a rubber tube and a fiber mesh, both ends of which are sealed by metal clamps. When the tube is filled with gas, the rubber tube will expand radially and contract axially to generate driving force, but this kind of driver cannot produce bending deformation and cannot be used to drive wrists and fingers to produce bending movements. [0003] The Chinese patent with th...
