Description

Row two-bladed micro helicopter

Technical field

The utility model relates to remote controlled model plane control technology field, relates in particular to a kind of row two-bladed helicopter structure.

Background technology

At present, row two-bladed helicopter in the remote controlled model plane, be with the vertical takeoff and landing (VTOL) device of rotor as its main lift source, existing row two-bladed helicopter flight attitude is controlled, the normal employing changes two sidespin wing angles and controls, and general rotor is to be handled by physical construction, make rotor forward, backward, left, be tilted to the right, produce forward, backward, left, horizontal component of force to the right, thereby make helicopter left and right sides all directions flight forwards, backwards.But the existing physical construction more complicated of handling the variation of rotor angle, as drawing horse etc. for a short time on the market, and the remote controlled model plane miniaturization becomes a kind of trend gradually, its consumer group mainly is the beginner, so this series products must be a low price, yet complex mechanical construction must cause the increase of cost, is unfavorable for popularizing of this series products, and the while complex mechanical construction also is not easy to helicopter and controls.

The utility model content

The utility model is in order to solve above-mentioned technical matters, and the row two-bladed helicopter at the bottom of a kind of simple to operate, cost is provided.

For addressing the above problem, the technical solution of the utility model is a kind of row two-bladed micro helicopter of structure, comprise the fuselage of the promising battery of inner encapsulation, laterally be located at the wing of waist, laterally be located at the flat wing of afterbody, the wing left and right side respectively is provided with one group of rotor assemblies, motor in the rotor assemblies signal receiver interior with being located at fuselage is connected, and motor is a variable speed motor.

Wherein, described rotor assemblies comprises body skin, be located at connecting arm in the body skin, be located at motor in the connecting arm, be located at motor gear on the motor drive shaft, with the big gear wheel of the parallel motor drive shaft axis of motor gear ingear rotation axis, comprise that also top is equipped with the rotor shaft of rotor, rotor shaft is set in the axis hole and connecting arm of big gear wheel, its end is resisted against on the main shaft block, rotor shaft and big gear wheel are flush fit, on the rotor shaft between big gear wheel and connecting arm, be equipped with the plain bearing of radial force between connecting arm and main shaft block.

The described rotor assemblies of described wing left and right side becomes to be symmetrical arranged.

The utility model sends the rotating speed of motor in the rotor assemblies of instruction control both sides by signal receiver, controls the inclination of helicopter by controlling variation that two motor rotary speeds control anti-torsion, reaches the purpose that helicopter flight turns to; The lifting of model copter increases simultaneously or reduces by the both sides motor rotary speed to be controlled.The utility model is simple to operate, can realize flicon by the control to motor rotary speed, makes the beginner who does not have the manipulation basis also can handle the helicopter smooth flight.The mechanics of helicopter is simple simultaneously, and it is low to have reduced productive costs, and aeroplane performance stability is improved greatly.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further, wherein:

Fig. 1 is the schematic perspective view of the utility model preferred embodiment;

Fig. 2 is the decomposing schematic representation of the utility model preferred embodiment.

The specific embodiment

Show the basic structure of the utility model preferred embodiment as Fig. 1,2, a kind of row two-bladed micro helicopter, comprise the fuselage 2 of the promising battery 1 of inner encapsulation, laterally be located at the wing 3 at fuselage 2 middle parts, laterally be located at the flat wing 4 of fuselage 2 afterbodys, wing 3 left and right sides respectively are provided with one group of rotor assemblies, and the motor 5 in the rotor assemblies is connected with signal receiver 6 in being located at fuselage 2.In the present embodiment, fuselage 2 is made up of left and

right body housing

15,16 butt joints, is provided with the chamber that battery 1 and signal receiver 6 are installed in the fuselage 2; Wing 3 two ends are provided with the pipe link that connects rotor assemblies; Because of the flicon of helicopter depends on the rotation speed change of motor 5, so motor 5 adopts variable speed motor.

In the present embodiment, the rotor assemblies of wing 3 left and right sides becomes to be symmetrical arranged, and the part in the rotor assemblies of both sides is formed identical.As shown in Figure 2, rotor assemblies comprises body skin 7, be located at the connecting arm 8 in the body skin 7, be located at the motor 5 in this connecting arm 8, be located at the motor gear 9 on this motor drive shaft, big gear wheel 10 with the parallel motor drive shaft axis of these motor gear 9 ingear rotation axiss, comprise that also top is equipped with the rotor shaft 12 of rotor 11, this rotor shaft 12 is set in the axis hole and connecting arm 8 of big gear wheel 10, its end is resisted against on the main shaft block 13, rotor shaft 12 is a flush fit with big gear wheel 10, on the rotor shaft 12 8 of big gear wheel 10 and connecting arms, 13 of connecting arm 8 and main shaft blocks are equipped with the plain bearing 14 of radial force.When rotor assemblies was installed, wing 3 two ends penetrated in the body skin 7, and the pipe link of its end inserts in the connecting arm 8.When motor 5 energisings, the motor drive shaft rotation, motor gear 9 on the motor drive shaft drives big gear wheel 10 rotations, drive rotor 11 rotations with big gear wheel 10 friction tight rotor shaft 12, rotor 11 can produce corresponding reactive torque when rapidly rotating, signal receiver 6 can send different instruction with control motor 5 rotating speeds, and the rotor 11 that is driven by motor 5 has respective change according to the different anti-torsion of motor 5 rotating speeds.
