Abstract

The utility model relates to a flying small angel toy, which comprises three direct current motors, two screw propellers 1, 3, a battery box 7, and a direct injection power transformer 6, wherein, a control knob is arranged on the battery box, the motors of the flying small angel toy are connected by electric wires, and the screw propellers can be controlled for inclining forwards and backwards. After flying to the sky, the flying small angel toy can fly forwards, fly reversely and turn in the sky. The utility model has the advantage of simple structure, and can simulate the flying action of a helicopter. Meanwhile, the utility model can cultivate the acute reactive skill of children, and can develop children's intelligence.

Description

Flying small angel toy

The utility model belongs to a kind of wired automatically controlled flying toy.

In the existing flying toy, flying power has mechanical spring, rubber band and motor etc., can only do single lift-off action of simply going straight up to, landing vertically, and control flight aloft after can not rising, as the CN87103272(electric lift-up toy system), lack a kind of toy of simulating real aircraft flight.

The purpose of this utility model provides a kind of novel flying toy, can lifting again aloft forward and back turn to the toy for children of flight, this toy can be cultivated the technical ability of the sharp reaction of children, exploitation children's intelligence.

The flight cherub has three miniature cocurrent electromotor 16-1,16-2,4-1, two screws 1,3, battery case 7, the cherub 2(of a dc source transformer 7 and a hand-held bouquet such as Fig. 1,2) it is made by plastic sheeting, its left foot point has a vent plug 5, is beneficial to flight aloft after the inflation.Adorn a motor frame 17 between cherub's back two wings, motor 16-1,16-2 oppositely are fixed into a square motor piece 16, and a pair of bearing pin 13 is arranged at its top, is mounted in the motor frame upper hole.Motor 16-1 axle head installs screw 1, motor 16-2 axle head installs roller gear 18, and with the motor frame on arc tooth plate 19 engagement, meshing point equals to mesh the radius of curvature of circular arc to the distance at bearing pin 13 centers, the roller gear motion, promptly form the forward and backward of motor piece 16 and move, the forward and backward inclination of screw before flies or inverted flight the flight cherub aloft.Respectively there is link stopper 19-1(Fig. 2 b at arc tooth plate 19 two ends), prevent that gear breaks away from tooth plate, a projection 15 is respectively arranged under motor piece 16 bearing pins, with 14 corresponding the matching of three grooves on the motor frame 17, make motor piece location.Spiral paddle core 20 inserts cross propeller hub 21, and with rivet 22 that the two riveting is fixed.Three motor of flight cherub 2 can be by the powered battery in the battery case, the direct current supply after the rectification of also available dc source transformer, and its connector inserts battery case hole 8 can cut off powered battery.A reversing switch 10(such as Fig. 3 K are arranged on the battery case ₁), the potentiometer 11(R of control screw 1 ₂) and control screw 3 potentiometer 12(R ₁), electric wire 9 is a stranded wire, and an end connects battery case, and the other end connects three motor of cherub.

The utility model flight cherub has two screws, and one produces lift, a generation pulling force, and the back of can going up to the air has the flare maneuver of helicopter in the forward and backward flight of certain altitude.Certainly, very slow as the toy flying speed.

Flare maneuver is achieved in that the projection of motor piece 16 is in the intermediate groove of 17 3 grooves 14 of motor rack, motor 16-1 and 4-1 running after the energising, screw 13 rotations, flight cherub lift-off, the deflection torque that screw produces with it the cherub and the mutual balance of pulling force of screw 3, when reversing switch 10 forward pluggeds, motor 16-2 running, gear 18 moves along tooth plate, until motor piece 16 projections 15 enter in the rear groove 14. This moment, screw 1 leaned forward, and the power that rotor produces is decomposed into two. Vertical stress component and the horizontal component that the cherub is flown forward that overcomes cherub's weight. Otherwise, switch 10 is moved reverse plugged to, gear 18 reverses, and projection 15 is decided piece, screw 1 hypsokinesis, the flight cherub is inverted flight, the resistance sizes of the potentiometer 12 of regulating electric machine 4, the rotating speed of change motor 4 changes the deflection torque that acts on the cherub, thereby realize left and right turning to or circular flight, so reach the effect that the flight cherub flies arbitrarily aloft.

Embodiment 1
