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

In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a transmission mechanism and a control method suitable for a waist rehabilitation robot. The transmission mechanism suitable for a waist rehabilitation robot includes a bracket, a pneumatic artificial muscle, a bottom plate, and a rope winding mechanism , guiding mechanism, rope, top beam, waist motion assembly and leg motion assembly. The control method can perform clamping when parking is required, so as to prevent rope disorder caused by inertia when parking suddenly. Beneficial technical effects: the present invention can supervise the state of the rope on the rope winding mechanism, prevent the rope from being messed up, and automatically provide pre-tightening force to the rope, avoiding the trouble of manually providing pre-tightening force, thereby realizing the intelligence of the mechanism, Improved safety, reliability and economic value.

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...
