Abstract

The invention provides a miniature multi-degree-of-freedom moving device of a rehabilitation robot. The miniature multi-degree-of-freedom moving device comprises a linear sliding rail, wherein the linear sliding rail is provided with a longitudinal sliding block, and the longitudinal sliding block is connected with the linear sliding rail in a sliding mode; an L-shaped connecting plate is connected to the longitudinal sliding block, transverse sliding rails are connected to the upper side and the lower side of the L-shaped connecting plate respectively, transverse sliding blocks are arranged on the transverse sliding rails and connected with the transverse sliding rails in a sliding mode, and the upper transverse sliding block and the lower transverse sliding block are connected with a steering connecting plate; and the steering connecting plate is connected with a force arm of a weight reduction device; and the L-shaped connecting plate is connected with weight reduction arms. Throughtwo groups of sliding blocks (the transverse sliding blocks and the longitudinal sliding block) and a mode of coupling of movements in two directions, the precision of the weight reduction values ofthe left weight reduction arm and the right weight reduction arm is improved, so the movement of the sliding blocks becomes smooth, and comfort in weight reduction is improved.

Description

technical field [0001] The invention relates to the technical field of rehabilitation robots, in particular to a miniature multi-degree-of-freedom moving device of a rehabilitation robot. Background technique [0002] Traditional rehabilitation robots use a hoist to reduce weight, and the weight-reducing arm is connected to the linear slide rail. During the reciprocating movement of the weight-reducing arm, the steel cable is pulled to generate a lateral force. If things go on like this, the linear slide rail will be deformed and the slider will move. Due to the limitation of the weight reduction method of the hoist, the weight reduction value of the left and right weight reduction arms of the rehabilitation robot can only be controlled to be the same. When the slider is stuck, the force on the left and right weight reduction arms is uneven, which will The hoist will affect and reduce the service life. Contents of the invention [0003] In view of this, in order to solve ...
