Abstract

The invention discloses a double-motor parallelly-driven human body activity assisting device, and relates to a human body activity assisting device. The device is capable of solving the existent contradiction between the high-power output demand and the compact structure mass light-weight demand in a current robot driving system, and the problem that the system mass is increased and the load and energy consumption of the human body are increased under the same power while the current robot driving system is applied to the human body activity assistance. The double-motor parallelly-driven human body activity assisting device comprises a power unit, a transmission unit and an executing unit. The power unit comprises a support frame, a sun gear driving motor, a sun gear driving motor output bevel gear, a driving shaft, a sun gear driving motor driving bevel gear, an annular gear output bevel gear, an annular gear, an annular gear driving motor output bevel gear, an annular gear driving motor and a sun gear. The sun gear driving motor and the annular gear driving motor which are axially and vertically installed are parallelly arranged on the support frame. The double-motor parallelly-driven human body activity assisting device is used for driving the exoskeleton robot joint, and assisting the human body activity.

Description

technical field [0001] The invention relates to a human body activity assisting device, in particular to a human body activity assisting device driven in parallel by double motors. Background technique [0002] At present, the use of motors in robot systems is to use one motor alone as a fixed drive device for a single joint. When there are more than one drive joints in the robot system, if a joint works alone, its maximum input power depends on Its corresponding drive motor limits the maximum output power of the joint. At present, if the robot joint needs to obtain more power, it is necessary to consider matching a motor with a higher power as the drive, but this will lead to an increase in the overall size and quality of the robot system. There is a contradiction between the need for high power output and the need for compact structure and light weight. If this driving method is applied to assist human body activities, under the same power, it will increase the system qu...
