Power source transmission structure

Abstract

The invention discloses a power source transmission structure which comprises a power source, a transmission shell and a screw rod assembly, wherein the transmission shell comprises a front end cover,a middle shell and a rear end shell; an adjusting cover is in threaded connection with the front end cover; a front end screw rod nut set is fixed at one end of a screw rod screw nut; the front end screw rod nut set is rotationally connected in the front end cover through a first bearing on a first connection section and is used for implementing axial limiting on the first bearing through the adjusting cover and a first limiting section; the other end of a screw rod nut is rotationally connected in the rear end shell; a threaded section of the transmission screw rod is connected in the screwrod nut; the power source is connected with the screw rod nut; and the screw rod nut rotates under driving of the power source to drive the transmission screw rod to move along a straight line. In theembodiment of the invention, the power source transmission structure has the advantages that the overall structure is compact and the transmission structure is tight, fit clearance of the transmission structure can be adjusted, stable operation of the transmission structure is ensured, and different transmission requirements can be met.

Description

technical field [0001] The invention relates to the technical field of rehabilitation equipment, in particular to a power source transmission structure. Background technique [0002] With the aging population and the increase of patients with lower extremity movement disorders caused by various diseases, rehabilitation robot technology combining rehabilitation medicine and robotics is gradually becoming a research hotspot at home and abroad. Currently, there are not many types of medical rehabilitation robots put into clinical use. Many, and immature in terms of mechanism design, modular design and computer control. [0003] The gait training rehabilitation robot is a device specially designed to restore the walking function of patients with walking impairments in the lower limbs. The biofeedback of the system can track the patient's gait during the lower limb training process in real time, and display it in the form of data and graphics; according to the biofeedback Based ...

AI Technical Summary

Problems solved by technology

[0005] The existing power source transmission structure has the problems of uncompact structure and untight transmission structure, which leads to the large volume of the power source transmission structure, and the problem of inconvenient installation and connection with mechanical legs or manipulators; in addition, the power source transmission structure takes a long time After operation, the transmission structure will produce a fit clearance, which will affect the transmission efficiency of the transmission structure, resulting in problems such as reduced rigidity, reduced torque, and easy vibration of the transmission structure.
