Abstract

The utility model discloses a driving mechanism of a toy car. The driving mechanism comprises a car frame, wherein four independent driving motors are arranged on the car frame; each driving motor is connected with wheels by a retarding mechanism; the retarding mechanism adopts the general mechanism such as a gear reducer; more than three rolling wheels are uniformly distributed on the outer surfaces of the wheels; the axes of the rolling wheels are not in parallel to the axes of the wheels; the axes of the rolling wheels on the same wheel have the same positions corresponding to the axis of the wheel; the axes of the rolling wheels on the four wheels are arranged in offset angles; the left wheels are symmetrical to the right wheels; and the front wheels are symmetrical to the rear wheels. In the driving mechanism, the eccentric rolling wheels are uniformly distributed on the surfaces of the wheels, so as to realize multi-direction forward motion; when the motors of the front wheels and the rear wheels as well as the left wheels and the right wheels have the opposite rotating directions and the same rotating speed, the toy car can do the left-and-right translation along the offset directions of the rolling wheels, therefore, by controlling the rotating directions and speeds of the driving motors, the toy car can move forward along any angle direction, the operability is enhanced greatly, and the gameplay is higher.

Description

The toy car driving mechanism

Technical field

The utility model relates to a kind of toy mechanical ﹠ electrical technology field, especially a kind of toy car driving mechanism.

Background technology

In existing toy, mostly toy car is can only advance, retreat or turn, can not the more direction of advance of the parallel mobile realization in the left and right sides, higher enjoyment can not be provided.

The utility model content

But problem to be solved of the present utility model provides the progressive toy car driving mechanism of a kind of each side.

The technical scheme that the utility model adopted is: the toy car driving mechanism comprises vehicle frame, four drive motors independently separately are housed on the described vehicle frame, described drive motors is connected with wheel by a reducing gear separately, reducing gear can adopt current mechanisms such as gear reduction unit, described wheel outer surface is evenly equipped with three with upper roller, described roller axle center is not parallel with axis wheel, each roller axle center relative wheel shaft core position is identical on the same wheel, roller axle center angle of eccentricity revolver and trailing wheel symmetry, front-wheel and trailing wheel symmetry on four wheels.

The uniform roller of described wheel outer surface preferably is dolioform, also can be elongated cylinder, and roller preferably adopts the rubber elastomeric material to make.

The beneficial effects of the utility model are: the utility model is by the roller in the uniform off-centre of wheel outer surface, realize the forward travel of a plurality of directions, when equating as and rotating speed opposite when the direction of motor rotation of front-wheel and trailing wheel, revolver and right wheel, can make the biased direction left and right sides translation of toy car along roller, like this by controlling the rotation direction and the rotating speed of each drive motors, the any angular orientation of realization toy car is advanced, and operability strengthens greatly, and playability is higher.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

Fig. 1 is the perspective view of the utility model specific embodiment;

Fig. 2 is the internal structure front-view schematic diagram;

Fig. 3 is the internal structure schematic top plan view;

Fig. 4 is the overall structure schematic perspective view of wheel;

Fig. 5 is the decomposition texture schematic diagram of wheel.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the toy car driving mechanism comprises vehicle frame 1, four drive motors 11 independently separately are housed on the vehicle frame 1, drive motors 11 is connected with wheel 13 by a gear reduction unit 12 separately, the wheel outer surface is evenly equipped with 8 rollers 14, roller adopts the rubber elastomeric material to make, as Fig. 4, shown in Figure 5, roller 14 axle center not with wheel 13 axis parallels, each roller 14 axle center relative wheels 13 axle center inflection point is identical on the same wheel, roller axle center angle of eccentricity revolver and trailing wheel symmetry on four wheels, front-wheel and trailing wheel symmetry, be the near front wheel upper roller axle center angle of eccentricity and the near front wheel left-right symmetry, simultaneously with left rear wheel front and back symmetry, by that analogy.

Because of each drive motors 11 relatively independent, by controlling turning to and rotating speed of each drive motors 11, can control the direction of advance of toy car, for example when front-wheel and trailing wheel, when opposite the and rotating speed of the direction of motor rotation of revolver and right wheel equates, the driving force that moves forward and backward is cancelled out each other, revolver then produces the power that advances along the direction of roller angle of eccentricity with right wheel, realize left and right sides translation, when the same side front and back wheel rotation direction and rotating speed identical, and the left and right wheels direction is when opposite, can realize the rotation of toy car original place, for example the near front wheel is identical with the left rear wheel rotating speed and turn round, and off-front wheel is also identical with left side wheel with the off hind wheel rotating speed and change forward, then can realize the rotation of counterclockwise original place, so also can realize arbitrarily angled the advancing of 360 degree by the rotating speed difference of each drive motors of control.

Above embodiment is a better embodiment of the present utility model; to set forth basic structure of the present utility model, principle, method; but can not limit protection domain of the present utility model; under the prerequisite that does not break away from the utility model main idea; according to above-described inspiration; those of ordinary skills can not need to pay creative work can implement multiple conversion/alternative form or combination, also belongs within the protection domain of claim of the present utility model.
