Problems solved by technology

The problem of direct drive is that there are many restrictions on space layout, insufficient motor torsional torque, and poor self-locking performance
The link drive can have more space options, and can provide a larger torque at a specific angle, and it is easy to realize the self-locking of the mechanism itself, but the problem of many link drive devices is that they are large in size and heavy in weight

Abstract

The invention relates to a wearable power knee joint rehabilitation device which is characterized by comprising an upper supporting plate and a lower supporting plate. A push rod driving mechanism is arranged on the upper supporting plate, a push rod outputting linear motion is arranged at an output end of the push rod driving mechanism, the end of the push rod is tightly connected with a cross connecting rod, two ends of the cross connecting rod are hinged to ends of connecting rods, the other ends of the connecting rods are hinged to the lower supporting plate, a first gear is fixedly arranged at the lower end of the upper supporting plate, and a second gear is fixedly arranged at the upper end of the lower supporting plate and engaged with the first gear.

Description

technical field [0001] The invention relates to a joint rehabilitation device, in particular to a wearable dynamic knee joint rehabilitation device. Background technique [0002] Auxiliary rehabilitation devices for the knee joint can generally be divided into wearable and non-wearable, power-driven and non-power-driven. Wearable auxiliary rehabilitation devices refer to devices worn outside the legs of the human body, which limit the extension and flexion of the joints within a suitable angle range, or maintain the knee joints at a certain angle, so as to promote early recovery of knee joint function. At present, the structure of wearable non-power-assisted rehabilitation devices is relatively simple, and generally supports and stabilizes the patient's damaged knee joint, and is relatively simple to use. Many power-assisted knee rehabilitation devices are non-wearable. This auxiliary rehabilitation device is more powerful than the wearable device. It can increase the pati...
