Description
Technical field
This utility model relates to a kind of biomimetic features, particularly relates to the bionic fish tail structure of a kind of eccentric transmission, belongs to bionical neck
Territory.
Background technology
The continuous progress and development of subject such as aquatic bionic, robotics, new material, and the growth requirement increase at sea,
The Biomimetic Fish exactly liking equipment for fish shape becomes the study hotspot of mechanical field.Biomimetic Fish can explore and further investigate seabed animals and plants money
Source, be widely used in underwater environment detection, harbour monitoring, search and rescue, humanitarian demining, seashore safety, fisheries management,
Counterterrorism operations and military operation etc..The research of the propelling pattern of Fish becomes the basis of Biomimetic Fish, and the propelling pattern of Fish is divided into spray
Penetrate formula, BCF propulsion mode (tail fin promotion), MPF propulsion mode (pectoral fin or abdomeinal fin promote), wherein BCF propulsion mode
High thrust can be produced and can move about at a high speed.In order to realize Biomimetic Fish miniaturization, motility and range of movement, such as fruit structure
Excessively complicated, Biomimetic Fish is overweight, is limited by material simultaneously, cannot simulate the complicated fortune of the Fish such as Spanish mackerel, tuna with this
Dynamic.
Summary of the invention
The purpose of this utility model is the bionic fish tail structure providing a kind of eccentric transmission in order to solve problem of the prior art.
The purpose of this utility model is achieved in that and includes caudal peduncle height, fish tail, micromachine, eccentric, described micro electric
Machine is arranged on caudal peduncle height, and eccentric is arranged on the output shaft of micromachine, and fish tail includes afterbody, intermediate bar and body,
Body coordinates with described eccentric wheel shape, and the end that intermediate bar is high with caudal peduncle is hinged.
This utility model also includes so some architectural features:
1. the material of caudal peduncle height, eccentric and fish tail is all fibre reinforced composites.
Compared with prior art, the beneficial effects of the utility model are: this utility model have employed a kind of new material and transmission shape
Formula, it is achieved the compound movement of the Fish such as Spanish mackerel, tuna, and there is simple in construction, the advantage that lightweight, efficiency is high.This
Utility model pass through micromachine connecting eccentric wheel, eccentric carry out 360 degree rotarily drive fish tail carry out left and right-60 °～60 ° wave,
Namely this utility model can realize simulating Spanish mackerel, tuna etc. by simple structure and use BCF propulsion mode (tail fin promotion)
The compound movement of pattern Fish.

Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
In conjunction with Fig. 1 and Fig. 2, this utility model includes that caudal peduncle is high by 1, fish tail, eccentric 4, micromachine 3, and fish tail includes tail
Portion 2, intermediate bar 6 and body 5, wherein material selects: eccentric selects carbon fibre composite, and caudal peduncle is high and fish tail selects
Glass fibre compound polyurethane material, it is relative to carbon fiber epoxy composite, and elastic modelling quantity is less, rigidity is lower, flexible
More preferably, deformation is bigger.Micromachine of the present utility model uses the small direct current generator of the whole series of maxon motor company of Switzerland to drive
Dynamic, volume is little, lightweight, and torque is big.Described micro motor is supporting includes decelerator and encoder.By micromachine 2 even
Connecing eccentric 4, eccentric 4 carries out shape and coordinates the further transmission realizing motion, the centre of fish tail with the body 5 of fish tail
The end that bar 6 is high with caudal peduncle is articulated and connected, and realizes fish tail swing further, and eccentric 4 carries out 360 degree and rotarily drives fish tail 2
Carrying out-60 °～60 °, left and right to wave, caudal peduncle high 1 is to support is integrally formed, and the bionic fish tail structure of overall eccentric transmission uses pin
Position.
This utility model belongs to bionic field, studies the Fish shape end of the month such as Spanish mackerel, tuna, relates generally to the spy of composite
Point and simple drive mechanism relate to a kind of bionic fish tail, and (tail fin pushes away to simulate the employing BCF propulsion mode such as Spanish mackerel, tuna
Dynamic) pattern Fish compound movement.
This utility model is by the following technical solutions: the bionic fish tail structure of eccentric transmission include caudal peduncle height, fish tail, eccentric,
Micromachine.Described caudal peduncle is high and fish tail is that the glass fibre compound polyurethane material in fibre reinforced composites is made, wherein
Caudal peduncle senior middle school includes micromachine and eccentric, driven by motor wobbler action so that it is tail fin moves, and described motor drives permissible
Fish tail swing is made to reach-60 °～60 °.
The utility model discloses the bionic fish tail structure of eccentric transmission, including caudal peduncle height, fish tail, eccentric, micromachine.
Described caudal peduncle is high and fish tail is that fibre reinforced composites are made, and wherein caudal peduncle senior middle school includes micromachine and eccentric, motor belt motor
Movable eccentric wheel moves so that it is tail fin moves, namely fishtailing motion is to be moved by minitype motor driving eccentric.This practicality
New Energy realizes such as Spanish mackerel, tuna etc. and uses BCF propulsion mode (tail fin promotion) pattern Fish compound movement, and has effect
Rate height, low cost, lightweight, advantages of simple structure and simple.
Described caudal peduncle is high and fish tail is that the glass fibre compound polyurethane material in fibre reinforced composites is made, described eccentric
It is also adopted by fibre reinforced composites to make；Eccentric is that carbon fibre composite is made specifically.
