(3) beneficial effect

The present invention provides a kind of children's tricycle based on aerodynamics, have it is following the utility model has the advantages that

(1), it is somebody's turn to do children's tricycle based on aerodynamics, when bicycle movement speed is very fast, front-wheel also can be corresponding Velocity of rotation become faster, so that the pumping exhaust velocity of air extractor is become faster, the air-flow being blown into inside ring tube can be made to become larger in this way, To apply thrust to sealing plate, makes sealing plate that internal activity ring and external activity circumferential direction be driven to move right, make fumer Exhaust outlet is located at the right side of power plate, and the right side of power plate can be made to generate biggish air-flow in this way, make the air pressure on the right side of power plate Less than the air pressure on the left of power plate, power plate is made to can produce a pulling force to the right in this way, to make the mobile speed of tricycle Degree is reduced；And the pulling force of the faster generation of movement speed of tricycle is bigger, in this way can movement speed to tricycle into Row control, reduces the damage to child leg.

(2), it is somebody's turn to do children's tricycle based on aerodynamics, when air-flow, which squeezes sealing plate, to move right, sealing plate A propulsive thrust can be equally generated to air-flow, air-flow is made to generate resistance to flabellum, so that rubber wheel be allow to generate resistance to front-wheel Power keeps the velocity of rotation of front-wheel slack-off, the movement speed of entire tricycle is made not become faster moment, so that children be made to ride It is safer in the process.

(3), it is somebody's turn to do children's tricycle based on aerodynamics, is taken out due to increasing a flabellum on tricycle Wind can consume a part of power when tricycle advances in this way, to make children can slightly laborious one when oneself is ridden Point improves the exercise effect to children, keeps the passive protective physical fitness of children more preferable.

(4), it is somebody's turn to do children's tricycle based on aerodynamics, when adult slightly pushes tricycle slowly to move ahead one After branch, the extraction wind that extractor fan can continue is clapped to ring tube, since airflow velocity is little, sealing plate will not be made to carry out Mobile, at this moment sealing plate keeps the left side of power plate continuous because stretch cord pulls the left side that fumer can be made to be located at power plate Air-flow is generated, so that air pressure on the left of power plate is less than air pressure on the right side of power plate using continual air-flow, power plate is made to generate one A thrust to the left, so that children be made not need excessive consuming physical strength during riding.

(5), it is somebody's turn to do children's tricycle based on aerodynamics, since setting sealing plate is by conical plate and circular slab structure At being preferably minimized sealing plate to the influence power of air-flow, before guaranteeing that big air-flow can drive sealing plate to carry out movement It puts, is preferably minimized influence of the sealing plate to little airflow, thus will not excessively expense when so that children's cycling tricycle is climbed Power.

(6), it is somebody's turn to do children's tricycle based on aerodynamics, multiple exhaust pipes are set in fumer, make gas in this way Flow it is more uniform flow to power plate, keep the air pressure thrust generated on power plate more average, so that it be made to apply tricycle Power be more convenient for controlling.
