Through intact full -tooth wheel and rack subassembly meshing transmission, drive the rack subassembly, control side arm and the reciprocal swing of fish tail realization, bionical fish tail advancing device simple structure is compact, and the symmetry is good, and the while can drive fish tail production reciprocal swing at the uniform velocity.
Description
Technical field
The utility model relates to mechanical equivalent of light feeding device field, is a kind of bionic fish tail propelling unit specifically.
Background technology
Bionical fish tail propelling unit has an enormous advantage in alerting ability, manipulative capability, propulsion coefficient etc., current various bionic fish tail propelling unit patents, having many is that link mechanism such as application crank rocker, crank block etc. produces reciprocal swing to drive fish tail, realize propelling forward, but these mechanisms often take up room comparatively greatly, be difficult to realization is arranged symmetrically with, and connecting rod mechanism drives fish tail to produce the speed of reciprocally swinging close to sine curve, speed is also uneven, in theory and be unfavorable for propelling forward.
Utility model content
The purpose of this utility model is to provide a kind of bionic fish tail propelling unit, fundamentally solves that existing bionic fish tail propelling unit propulsive force is uneven, take up room the problem such as large.
For achieving the above object, the utility model provides following technical scheme: this bionic fish tail propelling unit comprises housing, side arm, tooth bar assembly, partial gear, piston slider, cylinder body, bionic fish tail, it is characterized in that: described tooth bar assembly is slidably spacing in housing, tooth bar assembly comprises oval loop configuration, the inwall on the long limit of this loop configuration is respectively provided with a tooth bar, loop configuration two ends are provided with ear's structure of bar shaped, partial gear is spacing on housing, and be meshed with one of them tooth bar of tooth bar assembly, ear's structure is fixed with piston slider, piston slider is slidably spacing being fixed in shell end cylinder body, the piston slider other end is fixed side arm and is fixed, bionic fish tail is fixed with between the arm of the left and right sides, closed loop configuration is formed between two side arms and tooth bar assembly.
Cylinder body is separately fixed at housing two ends by the screw rod that four run through cylinder body and housing.
The beneficial effects of the utility model are: by adopting partial gear to engage slidably symmetrical structure gear assembly, side arm, piston slider, simple and compact for structure, symmetry is good, fish tail can be driven to produce at the uniform velocity reciprocally swinging, thus produce stable thrust.

Description of reference numerals: arm on the left of in the of 1; 2 screw rods; 3 left cylinders; 4 left piston slide blocks; 5 left bearing pins; 6 housing I; 7 tooth bar assemblies; 8 partial gears; 9 bearings; 10 right piston sliders; 11 right cylinder bodies; 12 right arm; 13 right bearing pins; 14 bionic fish tails; 15 housing II.
Detailed description of the invention
Below in conjunction with Fig. 1 ~ 2, describe content of the present utility model in detail by specific embodiment.This bionic fish tail propelling unit comprises the parts such as housing, side arm, tooth bar assembly 7, partial gear 8, piston slider, cylinder body, bionic fish tail 14.Wherein, tooth bar assembly 7 comprises oval loop configuration, and the inwall on the long limit of this loop configuration is respectively provided with a tooth bar, and loop configuration two ends are provided with ear's structure of bar shaped, are provided with reinforced rib between ear's structure of bar shaped and loop configuration.Housing is assembled by housing I, II6,15, and is provided with chute in the cavity fastened, and tooth bar assembly 7 is slidably spacing on chute, play the guiding role to the motion of tooth bar assembly.Partial gear 8 retains the gear teeth being slightly less than half full-depth tooth number, and make the form of gear wheel shaft, be installed on housing II15 by bearing 9, partial gear 8 can engage with upper and lower tooth bar inside tooth bar assembly 7 respectively, only can engage with the wherein side tooth bar of tooth bar assembly under mode of operation, to realize tooth bar assembly not crank motion in the same way.Left and right piston slider 4,10 is respectively by the ear's anatomical connectivity held about left and right bearing pin 5,13 and tooth bar assembly, left and right piston slider is slidably spacing being fixed in the left and right cylinder body 3,11 of shell end, and left and right cylinder body is separately fixed at housing two ends by the screw rod 2 that four run through cylinder body and housing.Left and right side arm is fixedly mounted on outside left and right piston slider by bolt respectively, and bionic fish tail 14 is bolted between left and right side arm, forms closed loop configuration between two side arms and tooth bar assembly.
When partial gear engages with one of them tooth bar of tooth bar assembly, tooth bar assembly 7 to a lateral movement, and then drives left piston slide block 4, right piston slider 10, left side arm 1, right arm 12 and fish tail 14 to a lateral movement; When partial gear engages with another tooth bar of tooth bar assembly, tooth bar assembly 7 moves to opposite side, and then drive left piston slide block 4, right piston slider 10, left side arm 1, right arm 12 and fish tail 14 to opposite side motion, thus realize the torque axis of partial gear to be changed to swinging of fish tail 14.Fish tail 14 is under tooth bar assembly 7 drives in the swing process of left and right, and during except left and right commutation position, tooth bar assembly 7 all can drive fish tail 14 to remain a constant speed motion, when left and right commutation position, can obtain very large acceleration/accel instantaneously again, obtain larger propulsive force.
