A kind of remote-controlled toy vehicle with front-wheel steer
Technical field
The utility model relates to the toy technique field, particularly relates to a kind of toy car with front-wheel steer.
Background technology
In the existing miniature remote controlled toy car, its steering mechanism all adopts the structure of motor and change-speed gearing, it mainly is by the motor-driven change-speed gearing, the angle that changes two front-wheels realizes the go to action of toy car, its complex structure, the cost height, be difficult to adapt to the needs of various micromachines simultaneously, at the problems referred to above, the automobile-used steering mechanism of a kind of miniature toys has appearred now on the market, it mainly adopts two coils is set in the vehicle body main body, a magnet is set on steering link, produce different magnetic directions by electric current to the logical different directions of two coils, and change the direction of toy car according to the magnetic direction of two coils on the steering link and the attraction between the magnet and repulsive force, but in the steering mechanism of this structure owing to adopt two coils and a magnet to make its active force each other not obvious, thereby the steering moment that steering link is produced is less, causes toy car to turn to unreliable and is easy to generate misoperation.
Summary of the invention
The purpose of this utility model is the problem at above-mentioned existence, a kind of micromachine that both gone for is provided, and simple in structure, cost is low, can produce bigger rotating torque again, guarantees that toy car rotates the remote-controlled toy vehicle that has front-wheel steer flexibly, reliably.
The technical solution of the utility model is achieved in that
A kind of remote-controlled toy vehicle with front-wheel steer, comprise the vehicle body main body, driving mechanism, a left side, right two trailing wheels, a left side, right two front-wheels, it is characterized in that a left side, right two front-wheels are respectively by a left side, right two preceding wheel seats are connected with the vehicle body main body versatilely with the loose fit socket of the axis hole that the vehicle body body front part is provided with, an and left side, be provided with by steering link between right two front-wheels and the vehicle body main body, the transfer and the resetting means that turn to controlling organization to form, wherein turn to controlling organization to comprise two magnet of device in vehicle body body front part cavity both sides, the coil that with control circuit be electrically connected of device in the anterior draw-in groove of steering link, wherein the relative side pole of two magnet is uniformly set, the two ends holding of steering link is on a left side, on the pin of right two preceding wheel seats, the part that its front end is equipped with coil is nested with in vehicle body body front part cavity, resetting means comprises back-moving spring and regulating rod, wherein the stiff end of back-moving spring is nested with in steering link end face front portion, its two lever arms end is positioned at the regulating rod both sides, and regulating rod is plugged in the vehicle body main body and is positioned at the steering link rear portion.
The utility model is owing to adopt two blocks of magnet and the structure of coil and steering link organic composition steering mechanism, both the displacement that makes steering link make certain distance by the relation that attracts each other and repel between coil and the magnet realized turning to flexibly of toy car, simultaneously the active force between two magnet and the coil is big, thereby make the steering moment of steering link also realize turning to of toy car greatly reliably, and the utility model is simple in structure, easy to manufacture, cost is low.
Describe basic structure of the present utility model and operation principle in detail below in conjunction with accompanying drawing:
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a decomposition texture schematic diagram of the present utility model;
Fig. 3 is a plan structure schematic diagram of the present utility model.
The specific embodiment
As Fig. 1~shown in Figure 3, the utility model comprises vehicle body main body 1, driving mechanism 2, a left side, right two trailing wheels 4, a left side, right two front-wheels 3, its characteristics are a left side, right two front-wheels 3 are respectively by a left side, the jack-post 32 of right two preceding wheel seats 31 is connected with vehicle body main body 1 versatilely with the loose fit socket of the axis hole that vehicle body main body 1 front portion is provided with, an and left side, be provided with by steering link 5 between right two front-wheels 3 and the vehicle body main body 1, the transfer and the resetting means that turn to controlling organization to form, wherein turn to controlling organization to comprise two magnet 6 of device in vehicle body body front part cavity both sides, the coil that with control circuit be electrically connected 7 of device in the anterior draw-in groove of steering link, wherein two magnet, 6 relative side poles are uniformly set, the two ends holding of steering link 5 is on a left side, on the pin 32 of right two preceding wheel seats 31, the part that its front end is equipped with coil 7 is nested with in vehicle body main body 1 front cavity, resetting means comprises back-moving spring 8 and regulating rod 9, wherein the stiff end of back-moving spring 8 is nested with in steering link 5 end face front portions, its two lever arms end is positioned at regulating rod 9 both sides, and regulating rod 9 is plugged in the vehicle body main body 1 and is positioned at steering link 5 rear portions.
Basic principle of the present utility model is:
When changing the galvanic positive-negative polarity of curved coil, the sense of current changes, then the direction in the magnetic field that coil produced also changes thereupon, and coil magnetic field was the N utmost point originally, become the S utmost point now, originally be the S utmost point, and became the N utmost point now, promptly the left side of coil is the S utmost point, the right side is the N utmost point, then the magnetic field on the left of coil this moment is opposite with the polarity of the magnetic field of the magnet of this side, and inhale mutually in two magnetic fields, produces attraction; The polarity of the magnetic field on coil right side is identical with the polarity of the magnetic field of the magnet on right side, repel each other in two magnetic fields, produce repulsive force, attraction is identical with the repulsive force direction, all,, moves to the left by coil so under the effect of these two power, driving steering link towards the left side, wheel seat swing certain angle before about steering link promotes, thereby the change of realization toy car direction.When the directionkeys of decontroling on the remote controller, then coil does not have electric current to pass through, and coil magnetic field disappears, and the magnet of both sides is inoperative to coil, and steering link is got back to meta under the effect of back-moving spring, and toy car recovers straight-line travelling.
