Abstract

The invention discloses a wearable flexible auxiliary operating arm, and relates to a flexible operating arm. The wearable flexible auxiliary operating arm comprises a gas chamber cover, a base, an inner spring and three flexible inflatable gas tubes, wherein each flexible inflatable gas tube is a guide tube which is sealed in one end and is open in the other end; the inner spring is arranged on the middle part of the base; the three flexible inflatable gas tubes are arranged in the peripheral direction of the spring; the sealed ends of the flexible inflatable gas tubes abut against the base;a gas chamber which is matched with the flexible inflatable gas tubes is arranged on the gas chamber cover; opening ends of the flexible inflatable gas tubes are fixedly arranged in the gas chamber; and a gas inlet and a gas outlet are formed in the gas chamber. The wearable flexible auxiliary operating arm is flexible in structure, can realize various motion forms, has very good convenience, is convenient to expand, and can be applied to different occasions according to the needs.

Description

technical field [0001] The invention relates to a flexible operating arm, in particular to a wearable flexible auxiliary operating arm based on a pneumatically driven continuum structure. Background technique [0002] From the perspective of application prospects, the flexible auxiliary manipulator arm has broad application prospects in post-disaster rescue, medical surgery, individual combat, and assisting the human body in complex operations. At present, most of the existing manipulator arms are mainly designed with rigid structures, which are bulky, have limited range of motion and poor flexibility, and the invariable stiffness leads to poor environmental adaptability. Therefore, it is necessary to design a flexible manipulator. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a wearable and flexible auxiliary operation arm based on pneumatic drive with flexible structure, good environmental adapt...
