Problems solved by technology

However, due to the characteristics of the flexible cable, the above-mentioned parallel flexible cable waist rehabilitation robot has the following disadvantages: during the movement of the reel, the rope will swing back and forth in the longitudinal direction due to the width of the reel, and even cause the rope to fall off on the pulley
The pre-tightening force of the rope needs to be manually added by the operator, which is very troublesome and imprecise
In actual operation, the motor is often stopped. Due to the inertia of the heavy object hanging at the other end of the rope, the rope is easily messed up on the drum, resulting in failure to work normally.

Abstract

To overcome the deficiencies of the prior art, the invention provides a transmission mechanism suitable for a waist rehabilitation robot and a control method. The transmission mechanism suitable for the waist rehabilitation robot includes a bracket, a pneumatic artificial muscle, a base plate, a rope winding mechanism, a guide mechanism, a rope, a top beam, a waist movement assembly and a leg movement assembly. According to the control method, the clamping can be performed when shutdown is required, and thus rope disorder caused by inertia during sudden shutdown is avoided. The transmission mechanism has the advantages that a state of a rope on the rope winding mechanism can be monitored, to prevent the rope disorder; a pretightening force is provided automatically for the rope, the trouble of manually providing the pretightening force is avoided, the mechanism intelligence is achieved, and the safety, reliability and economic value are improved.

Description

technical field [0001] The invention relates to the technical field of precise mechanical transmission, in particular to the field of automatic rope winding mechanism and control of rehabilitation robots, in particular to the transmission mechanism and control method suitable for waist rehabilitation robots. Background technique [0002] The waist is very important to the human body, and it is also a part that is very prone to health problems. In today's society, more and more people sit for a long time in work, study and life, which makes the lumbar muscles of the human body in a tight state for a long time, leading to diseases such as aging of the lumbar muscles. Waist rehabilitation training is the basic means of lumbar rehabilitation, but the existing lumbar rehabilitation treatment methods mostly rely on the trainer's experience, and the rehabilitation training equipment is relatively single. Therefore, improving the efficiency and safety of waist rehabilitation traini...
