Abstract

The invention relates to a miniature sonar two-degree-of-freedom servo mechanism based on a crank and sliding block mechanism, and belongs to the technical field of miniature sonar servo, and the problem that an existing servo mechanism is not suitable for miniature sonar installation is solved. The two-degree-of-freedom servo mechanism comprises a transverse transmission part and a longitudinal transmission part, wherein the transverse transmission part and the longitudinal transmission part are identical in structure; the transverse transmission part comprises a crank, a rocker and a slidingblock which are sequentially hinged, the crank of the transverse transmission part, a crank of the longitudinal transmission part and the miniature sonar are fixedly connected together, and the connection part is hinged to an installation carrier of the miniature sonar through a fixed ball; the sliding block of the transverse transmission part and a sliding block of the longitudinal transmissionpart can move away from or close to the miniature sonar independently in the parallel direction; and the transverse transmission part and the longitudinal transmission part are arranged orthogonally.According to the miniature sonar two-degree-of-freedom servo mechanism, the structure layout is reasonable, the height integration is realized, the rear-end installation space of the miniature sonar is fully utilized, the motions of the miniature sonar in the pitching and yawing directions can be achieved simultaneously, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of miniature sonar servo, in particular to a miniature sonar two-degree-of-freedom servo mechanism based on a slider crank mechanism. Background technique [0002] Sonar is an electronic device that uses the characteristics of sound waves to propagate underwater, through sound-to-electric conversion, to realize functions such as underwater detection and underwater communication. It is the most commonly used navigation and positioning technology for underwater vehicles and underwater robots. Sonar emits some form of acoustic signal, which is detected by the echo reflected by obstacles or targets on the way of signal propagation in water. [0003] The traditional installation method of sonar is fixedly installed at the front end of the underwater vehicle or underwater robot. There are limitations in emitting sound waves and receiving echoes, which seriously restricts the effective detection area of ​​sonar. T...
