Abstract

The invention relates to a compact type lower limb exoskeleton driving device. The compact type lower limb exoskeleton driving device comprises a high-rotation-speed direct current brushless motor (1), a planetary speed reducer (2), a worm (5), a worm wheel (12) and an output shaft (9), wherein the worm (5) is fixedly installed in an input end outer shell (4) through a bearing (6), the worm wheel (12) is fixed in an output outer shell (7) through baffles (10) on the two sides, the worm (5) is tightly meshed with the worm wheel (12) through worm teeth (11) on the worm (5) and, the high-rotation-speed direct current brushless motor (1) is connected with the planetary speed reducer (2) through a shaft, the planetary speed reducer (2) is synchronously connected with the worm (5) through a fixing connecting seat (3), a concentric bearing (8) is installed in the middle of the worm wheel (12), and the output shaft (9) is installed in the concentric bearing (8) through a spline coupler (13). The compact type lower limb exoskeleton driving device is compact in structure, can provide large joint driving moment, and has a reverse self-locking function.

Description

technical field [0001] The invention relates to an exoskeleton robot, in particular to a compact lower limb exoskeleton driving device. Background technique [0002] The joint drive of the lower extremity exoskeleton has the characteristics of large driving torque and small volume and weight as much as possible. However, most of the existing lower extremity exoskeleton joint drive devices are realized by directly installing the drive motor at the joint, which not only drives the torque It cannot be improved, and the installation space is relatively large, which makes it inconvenient to wear the exoskeleton robot. Contents of the invention [0003] The purpose of the present invention is to provide a compact lower limb exoskeleton driving device, which solves the problems of limited application range of torque of the current lower limb exoskeleton driving device, large space occupied by the whole device and inconvenient loading and unloading. [0004] In order to solve the...
