Abstract

The invention provides an active and passive energy storage combined driver which has broad application. For example, the active and passive energy storage combined driver can be used for jumping robots, wheeled mobile robots and the like. The active and passive energy storage combined driver comprises a motor mounting frame, a servo motor is fixedly mounted on the motor mounting frame, a ball screw rod is connected with an output shaft of the servo motor, a ball nut matched with the ball screw, and flange move along a guiding device, and an energy storage spring is fixed below the ball nut, the energy storage spring is mounted on the ball screw rod in a sleeved mode, a chassis is fixed to the lower end of the spring, and a clutch is further arranged between the lower end of the ball screw rod and the upper end of the chassis. The active and passive energy storage mechanism combined driver can effectively improve the utilization rate of energy.

Description

technical field [0001] The invention belongs to the technical field of robots, and in particular relates to a high-efficiency driver, which can be used for jumping robots, mobile robots and the like. Background technique [0002] Traditional robot drivers mostly adopt rigid structures, which often cause a lot of energy loss when encountering collisions, emergency braking, etc., which leads to the problem of low energy efficiency in existing robot drivers. Contents of the invention [0003] The purpose of the present invention is to solve the problem of low energy conversion efficiency in existing robot drive units, and to provide a drive with higher energy efficiency and a combination of active and passive energy storage on the premise of fully considering the passive characteristics of the spring itself. [0004] Technical scheme of the present invention is as follows: [0005] The active and passive energy storage combined drive provided by the present invention mainly ...
