Abstract

The invention aims to provide a flexible cable driving unit. The driving unit comprises a driving unit bracket, a revolving flexible cable guide device, a permanent magnet direct current moment motor, a fixed flexible cable guide device, a flexible cable traction wheel and a guide shaft, wherein the permanent magnet direct current moment motor is arranged outside the driving unit bracket; the flexible cable traction wheel is arranged in the driving unit bracket; an output shaft of the permanent magnet direct current moment motor is connected with the flexible cable traction wheel; the revolving flexible cable guide device is connected with the fixed flexible cable guide device through the guide shaft; the fixed flexible cable guide device is fixed in the driving unit bracket; the revolving flexible cable guide device and the guide shaft are arranged outside the driving unit bracket; and a flexible cable is wound on the flexible cable traction wheel and passes through the fixed flexible cable guide device, the guide shaft and the revolving flexible cable guide device. The flexible cable driving unit can drive the flexible cable in a spatial multi-degree-of-freedom mode, is modular,has a compact integral structure and light weight, and is convenient to transport, assemble and disassemble spatially.

Description

technical field [0001] The invention relates to a mechanical device for driving ropes in rehabilitation training. Background technique [0002] In the manned spaceflight industry, exploring long-term and effective comprehensive countermeasures against the physiological effects of weightlessness is a key issue that needs to be solved urgently in manned spaceflight. With the extension of space mission time and the increasingly complex and arduous tasks, the protective measures against weightless flight are also constantly being updated. At present, the protective measures for weightless flight are mainly carried out in the following aspects: (1) using negative pressure to change the distribution of body fluids; (2) scientific sleep; (3) drug treatment; (4) acupoint stimulation; (5) physical exercise; 6) Artificial gravity. Among them, physical exercise is the core content of the existing countermeasures. Physical exercise can improve astronauts' psychological stability, red...
