Abstract

The invention discloses a dual-drive gear device, comprising two driving wheels, a gear box and a movable gear shaft, wherein the driving wheels are arranged on the movable gear shaft; at least two motors and a gear set are arranged in the gear box; the gear set comprises four gears, wherein the gear A and the gear B are respectively fixed on the driving shafts of the first motor and the second motor, the gear C is arranged at a middle position below the gear A and the gear B and meshed with the same, and the gear D is fixed on the movable gear shaft and meshed with the gear C. According to the dual-drive gear device, a toy car is simultaneously driven by the two small motors, so that on the basis of obtaining same torque, the size of a rear wheel drive structure is greatly reduced; meanwhile, the small motors are used, so that current in a circuit is decreased, and then the circuit is not easy to damage and the service life is greatly prolonged.

Description

Dual Drive geared system

Technical field

The present invention relates to toy car, especially relate to a kind of Dual Drive geared system for toy car.

Background technology

Having a toy car is always the dream that each children wishes to have, and toy car can be given full play to children's imagination, helps user's study, exercise, the multidisciplinary scientific knowledge of integrated use, and can improve children's creativeness and interest.Generally speaking, common toy car drive unit is mostly to drive trailing wheel with motor collocation gear train, thereby make toy body there is movable function, if need to increase the horse-power-hour of toy, its usual way is to adopt large volume, powerful motor to drive, thereby cause the bulky of toy, easily make player produce sensation dry as dust, reduced interest and the attraction of toy; After toy has adopted large motor in addition, make the electric current that passes through in circuit excessive, fragile circuit, greatly reduction of service life.So develop a kind of high-power, long service life, and the little driving structure of rear wheel of volume just becomes a kind of exigence.

Summary of the invention

The object of the invention is to, for the existing above-mentioned deficiency of existing Dual Drive geared system, provide a kind of simple in structure, circuit to be difficult for damaged, and the little Dual Drive geared system of volume.

For achieving the above object, technical scheme provided by the present invention is:

A kind of Dual Drive geared system, it comprises the moving tooth axle that two driving wheels, a gear-box and stretch out from gear-box, described driving wheel is arranged on this moving tooth axle, is at least provided with two motors and a gear train in described gear-box, and described motor drives this gear train work simultaneously.

Described motor is two, and it is all located at gear-box top and arranges near top margin.

Described gear train comprises four gears, wherein gear A, gear B are separately fixed on the driving shaft of the first motor, the second motor, described gear C is located at the centre position of gear A and gear B below and engages with gear A, gear B, and described gear D is fixed on described moving tooth axle and engages with gear C.

The invention has the beneficial effects as follows: drive toy car by two fractional motors simultaneously, obtaining on identical moment of torsion basis, greatly dwindled the volume of driving structure of rear wheel, meanwhile, owing to having adopted fractional motor, the electric current in circuit is diminished, not fragile circuit, has extended service life greatly.

Below in conjunction with the drawings and the specific embodiments, the invention will be further described.

Accompanying drawing explanation

Fig. 1 is front view of the present invention;

Fig. 2 is the three-dimensional explosive view of Fig. 1.

The specific embodiment

Embodiment: referring to Fig. 1 and Fig. 2, a kind of Dual Drive geared system that the present embodiment provides, it comprises the moving tooth axle 3 that two driving wheels 1, a gear-box 2 and stretch out from gear-box 2, described driving wheel 1 is arranged on this moving tooth axle 3, in described gear-box, be provided with two motors 4 and a gear train, described motor 4 drives this gear train work simultaneously.The first motor 41 and the second motor 42 are located at gear-box top and are arranged near top margin.Described gear train comprises four gears, wherein gear A 21, gear B 22 are separately fixed on the driving shaft of the first motor 41, the second motor 42, described gear C 23 is located at the centre position of gear A 21 and gear B 22 belows and engages with gear A 21, gear B 22, and described gear D 24 is fixed on described moving tooth axle 3 and engages with gear C 23.

When the present invention uses, turn on the power switch, circuit board starts the first motor 41 and the second motor 42 simultaneously, the first described motor 41, the second motor 42 is respectively by gear A 21, gear B 22 driven gear C23 rotate, thereby gear C 23 drives the driving wheel 1 being located on moving tooth axle 3 to rotate by gear D 24, make toy body there is movable function, the present invention drives toy car by two fractional motors simultaneously, obtaining on identical moment of torsion basis, greatly dwindle the volume of driving structure of rear wheel, fractional motor because of what adopt in addition, so the electric current by each motor is less, circuit is difficult for damaged, greatly extend service life.

As described in the above embodiment the present invention, adopt structure same or analogous with it and other Dual Drive geared system of obtaining, all in protection domain of the present invention.

Claims
