A kind of novel toy motorcycle
Technical field
The utility model relates to toy for children field, is specifically related to a kind of novel toy motorcycle.
Background technology
In the market, the power shaft of toy motorcycle directly drives tyre rotation by wheel hub, owing to being and being fixedly connected with between tire, wheel hub and power shaft three, when the rotating speed of power shaft is slack-off or stop, tire and wheel hub are also thereupon slack-off or stop, cause the motional inertia of toy motorcycle poor, be difficult to maintain straight-line inertia, be difficult to keep holding up the balance in direction, toy motorcycle can be toppled over to both sides, particularly when toy motorcycle is in the time turning, cannot simulates real car in the bend action of turning that tilts, and be easy to topple over.
It is all to drive steering spindle by steer-drive that existing toy motorcycle turns to driving, drives front-wheel to swing and realizes and turning to, and this toy motorcycle lacks playability.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of rational in infrastructure, by controlling the centre-of gravity shift of toy motorcycle, realizes turning to of motorcycle, without drive deflecting roller to turn to by steering spindle.
The technical scheme that the utility model adopted is for achieving the above object:
A kind of novel toy motorcycle, it comprises vehicle body, front-wheel, trailing wheel, and be located at the moulding human body on vehicle body; Wherein, be provided with Power Drive Unit in a side of described trailing wheel, in described moulding human body, be provided with steer-drive, and this steer-drive makes moulding human body be connected with the afterbody of described vehicle body.
Described steer-drive comprises successively the motor A connecting, and turns to driving gear set and centre-of gravity shift parts, and wherein, described motor A is provided with output gear, and this motor A is located in described moulding human body, and output gear is located at the afterbody of vehicle body; Described turn to driving gear set and centre-of gravity shift parts are located at the afterbody of described vehicle body.
The described driving gear set that turns to comprises intermeshing one-level travelling gear and secondary transmission gear, and wherein, described one-level travelling gear engages with described output gear, and described secondary transmission gear is provided with groove, and described output gear is located in this groove.
Described centre-of gravity shift parts are provided with tooth bar, this tooth bar with described in turn to the secondary transmission gear of driving gear set to engage.
Described Power Drive Unit comprises motor B, and the power transmission gear group being connected with this motor B.
On the nave boss of described front-wheel and trailing wheel, be equipped with counterweight iron ring.
Described body bottom both sides are also provided with auxiliary wheel.
In described vehicle body, be also provided with battery case and control circuit board.
The beneficial effects of the utility model are: the utility model is realized and being turned to without control front-wheel steer axle, but drives moving left and right of centre-of gravity shift parts by steer-drive, changes the position of centre of gravity of car, and car is tilted, and realizes turning function.By counterweight iron ring is set on nave boss, greatly increase the quality of wheel, the inertia while having increased rotating of wheel, has kept the extraordinary degree of balance when car is travelled, even in the situation that speed is lower, still can keep balance.Respectively installed an auxiliary wheel in vehicle body both sides additional, played a supportive role, make product stop time unlikely fall down, in the time that remote controller continues to send the instruction of advancing, can move on.By groove is set on gear wheel, pinion is located in this groove, greatly save mechanism's requisite space.
