Abstract

The utility model discloses an electronic toy helicopter, which comprises a helicopter body, a propeller and a tail wing, wherein the helicopter body is fixed with a driving motor of which the output shaft is sleeved and fixed with an active gear, the active gear is in a tooth bonding with a slave gear which is provided with a slave shaft, the propeller is sleeved and fixed at the upper end of the slave shaft, the upper end of the propeller is further provided with an adjustable shelf which is fixed with a balance bar, the balance bar and the propeller are connected via the adjustable shelf and driven by the slave shaft. In the process of propeller's rotation, the balance bar can be adjusted automatically to enable the helicopter body to keep balance. The toy helicopter further has the advantages that the helicopter has simple and reasonable structure, and the propeller and the balance bar can be driven by only one driving motor.

Description

The electronic toy helicopter

Technical field

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

Background technology

Electronic toy helicopter on the market, its great variety of models with its stabilized flight be easy to control, is liked by people always and is subjected to.Manufacturer is the demand that satisfies the player, constantly develops the helicopter model of various styles and the improvement that continues.But existing toy helicopter still has the following disadvantages: at present popular toy helicopter is changed by prominent wind or heading when flight to be influenced, and causes the propeller swing, and the security of helicopter is relatively poor; For this reason, also the someone is designed to the model copter of double-vane, its structure generally is that two drive motors are set on fuselage, and drive corresponding rotor respectively by two drive motors, the model copter of this structure has improved the stability of flight to a certain extent, still, two drive motors is set on fuselage, not only increased manufacturing cost, its structure is also comparatively complicated.

The utility model content

The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and provides a kind of simple and reasonable for structure, and cost is low, can be driven the electronic toy helicopter of propeller and balancing pole thereof by a drive motors.

The purpose of this utility model is achieved in that

A kind of electronic toy helicopter, comprise fuselage, propeller and empennage, be fixed with drive motors on the described fuselage, cover has driving gear surely on the output shaft of drive motors, driving gear toe joint one driven gear, driven gear is provided with driven shaft, and the propeller cover fixes on the upper end of driven shaft, described propeller upper end also is equiped with travel(l)ing rest, is fixed with balancing pole on the travel(l)ing rest.Balancing pole is connected by travel(l)ing rest with propeller, and is driven by driven shaft, and in the process of propeller rotation, balancing pole can be adjusted automatically, so that the whole balance that keeps of fuselage.

The utility model can also adopt following technical measures to solve:

Drive propeller and balancing pole simultaneously as a drive motors, described propeller is made up of rotary sleeve and rotor, rotor is arranged on the lower end of travel(l)ing rest, balancing pole is installed in the upper end of travel(l)ing rest, rotary sleeve lower end cover fixes on the driven shaft, and travel(l)ing rest is arranged on the driven shaft upper end by central shaft.

Described balancing pole is made up of left and right balancing pole, and divides the relative both sides that are located at travel(l)ing rest, is convenient to debugging.

The beneficial effects of the utility model are: the electronic toy helicopter of utility model, by on propeller, setting up balancing pole, flexibly connect by travel(l)ing rest between balancing pole and the propeller, when flight, meet prominent wind or heading change, balancing pole can be swung along with propeller, to keep the whole machine balancing degree of helicopter; Moreover propeller and balancing pole drive by a drive motors, and it is simple and reasonable for structure, and adult is low.

The specific embodiment

As depicted in figs. 1 and 2, a kind of electronic toy helicopter, comprise fuselage 1, propeller 2 and empennage 3, be fixed with drive motors 4 on the fuselage 1, cover has driving gear 6, driving gear 6 toe joints one driven gear 7 surely on the output shaft 5 of drive motors 4, driven gear 7 is provided with driven shaft 8, propeller 2 covers fix on the upper end of driven shaft 8, and described propeller 2 upper ends also are equiped with travel(l)ing rest 10, are fixed with balancing pole 11 on the travel(l)ing rest 10.This structure electronic toy helicopter, be by on propeller 2, setting up balancing pole 11, flexibly connect by travel(l)ing rest 10 between balancing pole 11 and the propeller 2, when flight, meeting prominent wind or heading change, balancing pole 11 can be swung along with propeller 2, to keep the whole machine balancing degree of helicopter

Described propeller 2 is made up of rotary sleeve 201 and rotor 202, rotor 202 is arranged on the lower end of travel(l)ing rest 10, balancing pole 11 is installed in the upper end of travel(l)ing rest 10, rotary sleeve 201 lower ends cover fixes on the driven shaft 8, travel(l)ing rest 10 is arranged on driven shaft 8 upper ends by central shaft 12, sees Fig. 3 and shown in Figure 4.Because driven shaft 8 is driven by driven gear 7, the rotary sleeve 201 that cover is fixed on the driven shaft 8 rotates, rotor 202 and balancing pole 11 also rotate thereupon, because balancing pole 11 flexibly connects by travel(l)ing rest 10 and rotor 202, therefore, rotor 202 when rotated, balancing pole 11 is swing automatically, makes propeller 2 whole machine balancings.Described balancing pole 11 can be selected to be made up of left and right balancing

pole

1101,1102, and divides the relative both sides that are located at travel(l)ing rest 10.
