Swinging device, underwater bionic propeller and use thereof

Abstract

The application relates to a swinging device, underwater bionic propeller and use thereof. The swinging device can include a swing mechanism including a swing arm. A driving end of a steering mechanism can be in transmission connection with the swing arm so as to drive the swing arm to swing in a reciprocating manner. A reciprocating mechanism can be provided which is in transmission connection with a fixed end of a steering driving component so as to drive the swing arm to rotate in a reciprocating manner by driving the steering mechanism to move. The steering mechanism drives the swing arm independently and changes the swinging area that the reciprocating mechanism drives the swing arm to swing in a reciprocating manner.

What is claimed is: 
     
         1 . A swinging device, comprising:
 a swing mechanism, comprising a swing arm;   a steering mechanism comprising a driving end in transmission connection with the swing arm so as to drive the swing arm to swing in a reciprocating manner; and   a reciprocating mechanism, which is in transmission connection with a fixed end of the steering mechanism so as to drive the swing arm to rotate in a reciprocating manner by driving the steering mechanism to move;   wherein, the steering mechanism drives the swing arm to swing independently to change a swinging area of the reciprocating mechanism driving the swing arm to swing in a reciprocating manner, or the reciprocating mechanism drives the swing arm to swing independently to change a swinging area of the steering mechanism driving the swing arm to swing in a reciprocating manner.   
     
     
         2 . The swinging device of  claim 1 , wherein the swing mechanism further comprises a swing gear, the swing arm is connected to the swing gear, and a length direction of the swing arm is disposed at an angle to a rotation axis direction of the swing gear;
 the steering mechanism comprises a rack and a steering drive assembly, the swing gear is in transmission connection with the rack, and a driving end of the steering drive assembly is connected to the rack so as to drive the rack to reciprocate in a first direction and drive the swing gear to rotate in a reciprocating manner.   
     
     
         3 . The swinging device of  claim 2 , wherein the reciprocating mechanism comprises a reciprocating drive assembly and an output member, the reciprocating drive assembly drives the output member to reciprocate in the first direction, the output member is connected to a fixed end of the steering drive assembly to drive the steering drive assembly and the rack to move together in the first direction. 
     
     
         4 . The swinging device of  claim 3 , wherein the reciprocating drive assembly comprises an adjustable-amplitude sinusoidal mechanism, and an output end of which reciprocates in the first direction and is connected to the output member. 
     
     
         5 . The swinging device of  claim 3 , wherein the steering drive assembly comprises a screw assembly, the screw assembly comprising:
 a screw rod, which is in transmission connection with the rack, and one end of the screw rod is in rotary connection with the output member; and   a steering driving member, which is in transmission connection with one end of the screw rod deviating from the output member.   
     
     
         6 . The swinging device of  claim 3 , wherein the swing mechanism further comprises a transmission gear, and the rack is in transmission connection with the swing gear through the transmission gear. 
     
     
         7 . The swinging device of  claim 6 , wherein the swing mechanism further comprises a transmission assembly, the transmission gear is in transmission connection with the swing gear through the transmission assembly, and the transmission assembly comprises a belt transmission assembly or a chain transmission assembly. 
     
     
         8 . An underwater bionic propeller, comprising the swinging device of  claim 1 . 
     
     
         9 . A use of the swinging device of  claim 1  in a bionic bird.
