Description

A kind of model helicopter

Technical field

The utility model relates to the electronic toy field, refers to a kind of electronic model helicopter especially.

Background technology

The model plane aircraft is subjected to liking of numerous children even adult deeply with its good interest, recreational.The model plane aircraft can steadily circle in the air in the high-altitude, and conversion direction needs it can overcome self gravitation flexibly and comfortably, also needs the heading control loop of precise control.

Because the model plane aircraft is the aircraft that overweights air, when the model plane aircraft flies, will produce the air force that acts on aircraft aloft, various model plane aircraft are by air force lift-off flight.Utilize two fluid theorems: continuity theorem and Bernoulli's theorem, the model plane aircraft that overweights air overcomes self because of the gravity that terrestrial gravitation forms by the lift that obtains, and just can hover on blue sky.

Yet the heading control loop of traditional model plane aircraft adopts two paddle structures usually, needs two grip assemblies to rotate the flight that realizes body to control two oars accordingly, and rise and fall, forward-reverse and the left-right rotation of control body.Corresponding model plane aircraft volume is bigger, and weight is heavier, causes body volume bigger, and body weight is heavier, and assembling is relatively complicated, the assembling difficulty.

Therefore, in order to address the above problem, it is necessity to overcome the deficiencies in the prior art in fact that a kind of single-rotor helicopter simple in structure, that have a smooth flight is provided.

Summary of the invention

At the deficiencies in the prior art, main purpose of the present utility model is to provide a kind of simple in structure, single-rotor helicopter of having a smooth flight.

The utility model adopts following technical scheme:

Described T shape frame top is provided with the blade folder, and the middle part of described T shape frame is provided with balancing pole, and the outside of described T shape frame is with the frame ring, and described balancing pole connects blade folder, a pull bar link ring with a pull bar simultaneously through described T shape frame;

Described pitch comprises inner disc and outer dish;

The two ends of described ring are connected and fixed on the inner disc of described pitch with pull bar.

Further, described rotary components also comprises blade, and described vanes fixed is pressed from both sides in described blade.

Further, described rotary components also comprises counterweight, and described counterweight is fixed in described balancing pole end.

Preferably, described Power Component comprises motor, motor master gear and battery, and described motor master gear is fixed in described main shaft, the described motor master gear of described driven by motor.

Another is preferred, described empennage comprises tail motor, tail transmission shaft, tail gear, tailing axle and caudal lobe sheet, described tail motor is fixed in described main body, fixedly connected with the tail motor with the tail gear respectively in described tail transmission shaft two ends, described tailing axle is connected with described tail gear shaft, and described caudal lobe sheet is fixed in described tailing axle.

Preferably, described model helicopter also comprises a steering wheel, and described steering wheel is connected by pull bar with the outer dish of described pitch.

Preferably, described model helicopter also comprises a receiver, and described recipient is controlled described steering wheel.

The model helicopter that the utility model provides, its rotary components comprise main shaft, be arranged at the T shape frame of described main shaft upper end and be arranged at the pitch at described main shaft middle part, and T shape frame top is provided with the blade folder, and blade folder two ends are fixing a slice blade respectively.Middle part at described T shape frame is provided with balancing pole, the outside of described T shape frame is with the frame ring, and described balancing pole connects the blade folder with a pull bar simultaneously through described T shape frame, one pull bar link ring, the two ends of frame ring are connected and fixed on the inner disc of described pitch with pull bar.Therefore, this model helicopter has only a width of cloth oar, i.e. single-blade structure.Correspondingly, balancing pole, counterweight, Power Component and the pull bar etc. of controlling this oar have also reduced, and therefore, this model helicopter is simple in structure, handling ease.Compare two paddle structures, the model plane aircraft of the single-blade structure that the utility model provides, its Control Component has reduced half at least, therefore, body weight is lighter really, and volume is littler, and fuselage is light, and center of gravity is handy during operation, be difficult for breaking, crash resistance can be superior, and it is simple and safe to fly.

To sum up analyze, single-blade model helicopter of the present utility model has that destructing is simple, volume is gently little, have a smooth flight, control easy characteristics.
