Description

A kind of toy car for convenience detach

The utility model relates to a kind of electric toy car.

Now, the electric toy car that occurs on the market, its reduction box generally are to be positioned on the car body, make one with car body, reduction box inside parts such as reduction gearing are installed; Because existing toy car reduction box is to fixedly install, make it can't integral replacing, as the travel speed of need conversion toy car, can only and change its inner reduction gearing and realize by dismounting, do the comparatively difficulty that can waste time and energy also like this, therefore, toy car just keeps single speed to travel; Owing to lack the variation of speed, easily make the consumer feel dull, dull, thereby lose to toy car interest.And other parts of toy car also are to be fixedly mounted on the car body as motor, wheel, switch etc., and above-mentioned a certain part is in case aging or when being damaged because of reasons such as collisions, because each parts are closely to be fixed on the car body, inconvenient dismounting and change, therefore whole toy car can only be discarded, and will cause unnecessary loss and waste like this.

The purpose of this utility model provides and a kind ofly can adjust easily, the electric toy car of conversion travel speed.

Another one purpose of the present utility model provides a kind of dismounting, replacing main parts size electric toy car be convenient to.

The utility model comprises car body, is arranged on the front-wheel of Vehicular body front, switch, be arranged on the car body middle part the battery case that has contact chip, be arranged on motor assembly, trailing wheel and decelerator in the rear vehicle motor installation cavity, described decelerator is arranged on independently in the driving box, driving box is installed in hull back, and described trailing wheel is installed in driving box two sides.

Be convenient to dismounting for making motor, change, described motor assembly comprises the conducting strip on the motor installation cavity header board that is arranged on rear vehicle, vertical holding is at the preceding buckle of motor installation cavity front portion, the motor cover plate of holding on the motor installation cavity, wherein conducting strip is arranged on and the corresponding position of motor electrode contact chip, preceding buckle is provided with the groove that matches with motor tail end shape, motor is installed in the motor installation cavity of car body, before embedding, supports in the buckle groove and by preceding buckle its tail end, the electrode contact plate of motor contacts with conducting strip, and the motor cover plate buckles on motor.

Therefore the utility model can dismantle, change driving box and inner parts such as reduction gearing thereof easily because decelerator is arranged on one independently in the driving box, adjusts the speed of toy car as needs, as long as simply with the driving box integral replacing; Make toy car by only having single speed originally, become by providing for simple replacement of driving box and have multiple different speed, like this, both increased children's entertainment interest, can cultivate the ability of starting, beat one's brains that improves children again.Because of the main parts size of toy car all is detachable, so toy car is as causing the damage of individual parts because of aging or collision, can be by the parts of changing damage with its reparation, perhaps with after intact parts are pulled down on the toy car that damages, part is installed on other toy car as an alternative, so just can reduce unnecessary waste.
