Abstract

The invention discloses a bionic fish swinging joint integrated driving device. The bionic fish swinging joint integrated driving device comprises a waist joint outer rotor integration motor and a steering joint outer rotor integration motor, wherein a waist joint outer rotor integration motor rotor serves as a machine base for a bionic fish tail framework and the steering joint outer rotor integration motor, a steering joint outer rotor integration motor stator is fixed to the waist joint outer rotor integration motor rotor, and a steering joint outer rotor integration motor rotor serves as atail fin framework of a bionic fish. The driving device serves as a power system of the bionic fish to achieve the function of propelling and steering of the bionic fish. Compared with a traditionaldriving device with a speed reducing mechanism, the bionic fish swinging joint integrated driving device has the advantages of being low in noise, modularized, low in fault rate and high in efficiency.

Description

technical field [0001] The invention relates to an integrated drive device for a bionic fish swing joint, belonging to the technical field of underwater bionic fish drive devices. Background technique [0002] At present, the underwater bionic fish drive system mostly adopts the scheme of high-speed motor and large reduction ratio reducer. This scheme can have the characteristics of small weight and large output torque, but because it needs to work underwater, it is necessary to use a sealed structure to ensure the drive system. Therefore, the cost of the driving device is high, and because the bionic fish needs multi-joints to work together, it leads to problems of high noise and poor stability. At the same time, the use of a large reduction ratio reducer results in low system efficiency, which in turn leads to the battery life of the underwater bionic fish. Short time issue. Contents of the invention [0003] The present invention aims at the technical problems of the e...
