Electric propeller toy helicopter of the present invention can be implemented in the following manner.
The rare earth steel of installing is [NdFeB, SmCo in the rare-earth electric motor (4)
5, PrSmCo
5, Ce (CoCuFe)
5, Sm

17] material, magnetic energy product is 15-37, can both satisfy motor and produce enough magnetic field, and toy motor all is a ferrite magnetic steel at present, its magnetic energy product is 3 because of a little less than the magnetic field, Motor torque is little, efficient is low, be used for helicopter, lift is very little, the rare-earth electric motor shell uses low carbon steel. and wall thickness is the 0.5-0.8 millimeter, be to consider to reduce leakage field and weight factor, rare earth watt type magnet steel, use inside and outside Different Diameter garden, electric efficiency is very high, but when adopting with the garden, footpath, obviously weight reduction of motor housing, line cutting watt type magnet steel can reduce cutting area and material-saving again, thereby reduce cost, dress three-flute rotor in the motor, coiling is the 70-80 circle, line directly is the 0.21-0.23 millimeter, silicon steel sheet is the 17-22 sheet, motor Niu Lida maximum (motor weight relatively) is chosen above wherein one group of data, the rare-earth electric motor weight of device is less than 19 grams, equate with the toy motor minimum gauge, and the common brush of the big several times of moment of torsion (relative voltage electric current) brush, adorn copper oil bearing before and after the motor, can hold up to high speed more than ten thousand rev/mins.
The electronic toy helicopter, fuselage, screw, tail-rotor, the basin gear wheel, gear, undercarriage, outer tube adopts die sinking injection molded, but impact resistance, adopt double split injection moulding assembly unit better during the fuselage die sinking, the set vivid window of fuselage (44) is used the plastic uptake good decorating effect, power transmission shaft 2-2.2 millimeter steel axle, intensity is enough, the motor lead adopts inner core multiply copper cash softer, the thin favourable weight reduction of crust, balance bracket is that can its helicopter the balance landing. the aerial stable critical component that hovers, because of screw meeting wing drop certain angle when rotating, so can not force, can only allow its free adjustment inclination angle, set counting uses the from bottom to top suitable power of latch (14) to withstand the spiral general in groove, briquetting (15) is suitable from top to bottom defeats screw as the rotating shaft situation, makes its screw tip can regulate the inclination angle automatically.
The remote controller shell, the pressure regulation button is a plastic casing, available general dry battery in it, or rechargable battery, and charger, be in series voltage 6-9 volt, the pressure regulation button is under the pulling force of elastic or spring, shell fragment and copper sheet, resistance wire or series diode (each diode can fall 0.6-0.7 volt voltage) are in open position, promote the pressure regulation button and make it begin to collapse and connect circuit turn-on, but this moment, resistance reached maximum, helicopter is in ground and rotates the preceding pressure regulation button that pushes away, resistance reduces, and circuit voltage raises, aircraft begins to rise, when reaching terminal point, resistance is zero (relatively), helicopter stops height in empty institute, depends on the adjustment of voltage.
Screw adopts various wing can both flights, wherein is light with the convex concave, easily regulates lift and centrifugal force with convexo-plane, easily causes the aircraft overall weight to increase, increases power consumption with lenticular oar, and when the screw number of sheets was the 2-3 leaf, balance bracket should be 2-3 jack mutually.
Accompanying drawing 1 tail-rotor helicopter, use tail-rotor are that symmetric screw propeller produces reaction force.
Accompanying drawing 2 tandem helicopters, the active force of front and back screw is cancelled each other.
In accompanying drawing 1, accompanying drawing 2,3 three kinds of helicopters of accompanying drawing, the device mini charger, or small size dry cell in light weight and receiver, by charger or dry cell is dc source, connect the rare-earth electric motor lead, by receiver operation voltage height (control respectively lies prostrate voltage contact and wire contact or wire contact one end and moves on resistance wire), by reequiping conventional transmitters in the remote controller housing, helicopter can be realized wireless remote control again.
Because power supply and receiver ic circuit, must increase helicopter weight, but wireless remote control can alleviate wire weight, reduce conductor resistance, helicopter lift increases, and maximum should be got in the interior three-flute rotor of motor this moment, coiling line footpath, to increase electric current, continue increasing lift and just can satisfy each helicopter flight condition, wherein used receiver and transmitter, should be the simple motion that wireless remote controller action control voltage up-down general on the model plane disconnects.
Embodiment:
Parts:
Fuselage, undercarriage (shop is on sale), 60 tooth basin gear wheels, 21 tooth basin gear wheels, 2.2 steel axles, resistance wire, shell fragment, copper sheet, No. 2 battery 6 joints, lead, aviation model propeller (replacement tail-rotor), gear 7 teeth, lines cut Nd-Fe-B magnet steel, get with garden, footpath 1.8 millimeters thick, magnetic energy product 32, motor overcoat, toy motor (bias tyre), lead, plug, socket, balance bracket (bamboo), screw (wooden) counterweight, elastic.
Press Fig. 1 assembling, the scarce parts of motor dress system time institute replenish from toy motor, the pressure regulation button should good especially slip during remote controller, after all intact, conscientiously debugging, step is: cover connects plug and socket, promote the pressure regulation button, the inspection motor rotates, screw rotates, screw is looked in sight, whether tail-rotor balance, should slowly push away the pressure regulation button during flight, heighten voltage, helicopter just can progressively raise, in-flight above, helicopter goes wrong, crucial at screw, must there be a cover feasible method to regulate, grasps rotating speed, blade angle, the heavy factor of screw can make just that aircraft flies out dynamically.
