Problems solved by technology
[0003] However, the above-mentioned ankle joint rehabilitation robot has the following disadvantages when in use: 1. The movement of the first link and the second link in the transmission member is non-directional, resulting in abnormal noise and jamming of the link mechanism during use. ;2. The first shaft hole and the second shaft hole in the second connecting rod are both blind holes, and the lubrication effect is not good

The invention provides a transmission assembly, an ankle joint turnover mechanism and an ankle joint rehabilitation trainer, and relates to the technical field of ankle joint rehabilitation equipment. The invention provides a first connecting rod, a force conduction sleeve, a second connecting rod and a force storage elastic piece. One end of the first connecting rod is slidably and rotatably connected to one end of the force conduction sleeve, and the other end of the first connecting rod is used for being connected with a foot bracket; one end of the second connecting rod is slidably and rotatably connected to the other end of the force transmission sleeve, and the other end of the second connecting rod is fixedly mounted on a shell of a rotating motor or an ankle-foot bracket; the two ends of the force storage elastic piece abut against the end, away from the force transmission sleeve, of the first connecting rod and the end, away from the force transmission sleeve, of the first connecting rod respectively. The transmission assembly provided by the invention not only can keep the telescopic freedom degree of the force conduction sleeve, but also can break the zero stress state of the force conduction sleeve, so that the force conduction sleeve has the preferential movement directivity, and the jamming phenomenon is greatly improved.
Description
technical field [0001] The invention relates to the technical field of ankle joint rehabilitation equipment, in particular to a transmission assembly, an ankle joint turning mechanism and an ankle joint rehabilitation training device. Background technique [0002] The invention patent with the existing application number CN202111225228.7 discloses an ankle joint rehabilitation robot, which includes a first bracket, a second bracket, a third bracket and a transmission member to form a space linkage mechanism, and the second bracket is on the first bracket. The left and right rotation of the third bracket and the left and right turning of the third bracket on the second bracket constitute a linkage. When the second driving device drives the second bracket to rotate left and right on the first bracket, it also drives the third bracket to turn left and right on the second bracket. The two driving devices can realize the synergistic action of the ipsilateral ankle joint in intern...
