Abstract

The utility model relates to the technology field of toy product, more particularly a toy vehicle provided with tracking, which comprises a vehicle body frame, wheels mounted on the frame and a driving mechanism for driving wheels. The wheels comprise a group of steering wheels. The steering wheels are composed of two wheels with a certain included angle, wherein the wheels are provided with smooth wheel faces. During the rotation of the two steering wheels in the utility model, due to the included angle existing between the wheel axles of the two steering wheels, deflection will appear if the accepted frictional resistance is inconsistent with each other. Therefore, when the vehicle body in the utility model arrives at the bending position of the crayon track, one of the steering wheels will firstly contact the crayon track. At this time, the accepted friction force of the wheel in the bending angle is more than the friction force of the outer wheel. The vehicle body driven by the steering wheels will deflect along the crayon track. The utility model has great fun, simple structure and comparatively strong market competitive power.

Description

Toy car with track following

Technical field:

The utility model relates to the toy product technical field, refers in particular to a kind of toy car with track following.The track that this toy car can be drawn with wax crayon in the plane according to the user from this track of motion tracking, moves along track.

Background technology:

Our common seen toy car generally includes two types at present: a kind of is mechanically driver type, adopts clockwork spring or other elastic materials as power source usually.Another kind is an electrodynamic type, drives wheel by motor and advances.Common mechanical toy car structure is comparatively simple; and the toy car operational mode is comparatively single; running orbit is a straight line; interesting relatively poor; if need toy car track operation according to the rules; usually can only adopt track pattern, be about to vehicle and be placed on the track of making, make vehicle orbit.DYN dynamic toy car is owing to adopt battery as power source, and its driving force can steadily be exported, and just can realize that in conjunction with other circuit (as the remote sensing circuit etc.) remote control of automobile turns to, and track following etc. are all multi-functional.But adopt the electronics mode to realize that above-mentioned functions can make the total complexity, the cost of product improves.

The utility model content:

Technical problem to be solved in the utility model just is to overcome the deficiency of present like product, and a kind of toy car that adopts mechanical system to realize track following is provided.The utility model can move along the wax crayon track that the user draws in the plane.

For solving the problems of the technologies described above, the utility model has adopted following technical scheme: it comprises car body frame, rack-mounted wheel, and the driving mechanism that drives wheel, described wheel comprises one group of deflecting roller, this deflecting roller is made of two wheels in a certain angle, and wheel has smooth wheel face.

Described wheel also comprises an independent wheel, and two wheels in this independent wheel and the deflecting roller are isosceles triangle and distribute, and promptly wheel is positioned on the two wheel medium lines separately.

Two wheels in the described deflecting roller are by gears engaged, and one of them gear is connected with driving mechanism, and described deflecting roller is synchronous rotation with independent wheel.

Described driving mechanism adopts clockwork spring and gear train to drive.Perhaps also can adopt electro-motor and gear train to drive.

Be coated with all-purpose card moulding cladding on the described car body frame.Overall image of the present utility model so just becomes casper, increases the interest of product.

After the utility model adopts this structure, have certain angle between its two deflecting roller, and wheel face is smooth flat, but not adopts rubber tyre in the conventional toy car with decorative pattern.It is bigger to adopt this mode can make deflecting roller influenced by frictional force, and two deflecting rollers are in running, if suffered frictional resistance occurs deflection will occurring, when both sides frictional force unanimity, then along straightaway when inconsistent.The utility model utilizes this principle just and designs, when car body when the wax crayon track is advanced, in the ideal case, car body will advance along rectilinear direction, but when car body arrives the crooked place of wax crayon track, a wheel of deflecting roller will at first touch the wax crayon track this moment, be in this moment the wheel of bending interior angle suffered frictional force will be greater than the frictional force of outside wheel, thereby reach the purpose of car body along the wax crayon trajectory deflection.

Independent wheel in the utility model plays the driving effect, and adopts this independent wheel not only can guarantee the even running of whole locomotive body, and tricycle structure helps the turning of car body.

The specific embodiment:

See Fig. 1～4, the utility model comprises car body frame 1, wheel and the driving mechanism 4 that drives wheel.

Wheel comprises one group of deflecting roller 2 that is positioned at the front and the independent wheel 3 that is positioned at the rear.Deflecting roller 2 is made of two wheels in a

certain angle

21,22, and

wheel

21,22 has smooth wheel face.Two

wheels

21,22 in wheel 3 and the deflecting roller 2 are the isosceles triangle distribution separately, and promptly wheel 3 is positioned on two wheels, 21,22 medium lines separately.The utility model adopts three wheel mechanisms not only can keep the even running of car body, and helps the turning of car body.Wheel 3 adopts rubber wheel separately, can increase frictional force like this, helps advancing whole locomotive body to be moved forward.

Deflecting roller 2 and independent wheel 3 are all by driving mechanism 4 driven in synchronism.Driving mechanism 4 adopts clockwork spring 41 and gear train 42 to constitute usually, selects to have the gear train 42 of suitable gearratio according to the transmission of clockwork spring 41 dynamics sizes and speed output.Clockwork spring 41 drives deflecting roller 2 and wheel 3 separately simultaneously by gear train 42, and deflecting roller 2 and separately the rotating speed of wheel 3 be consistent, to guarantee the even running of toy car.Two

wheels

21,22 in deflecting roller 2 are by gears engaged, and promptly one-body molded on two

wheels

21,22 have a helical gear, by engagement between two

helical gears wheel

21,22 linked together.One of them gear 21 is connected with driving mechanism 4, and promptly driving mechanism 4 drives wheel 21, and wheel 21 drives another wheel 22 synchronously by gear drive.

Certainly, the rotating speed of deflecting roller 2 and wheel 3 separately also can there is some difference, and this can not influence normal use of the present utility model.

Angle between the

wheel

21,22 in the deflecting roller 2 is 90～180 degree, and its best angle is between 90～100 degree.

In addition, above-mentioned driving mechanism 4 also can adopt electro-motor, and by the electrical motor driven wheel, its structure is similar, gives unnecessary details no longer in detail here.

See Fig. 5, when using the utility model, (for example desktop) gone up and marked a running orbit 5 with wax crayon on the plane, rotate clockwork spring 41 swing handles 411 then, make clockwork spring 41 gather potential energy, unclamp swing handle 411 after, car body is placed on the track 5, and makes track 5 between steered wheel 21,22.After decontroling car body, car body will move ahead under the driving of deflecting roller 21 and independent wheel 3, and keep linear running.When first in the track 5 of car body operation turned right 51 position, because car body still keeps straightaway, the wheel face that be positioned at the wheel 21 on the right this moment will at first touch wax crayon track 5.We know, the track that wax crayon produced is the wax material marking that forms on the table in fact, frictional force between itself and the wheel wheel face is greater than the frictional force between desktop and the wheel, You Bian wheel 21 suffered frictional force will be greater than the left steering wheel 22 that does not contact wax crayon track 5 like this, add that owing to existing angle between the wheel shaft between the steered wheel, deflecting roller 2 will produce and turn to this moment.When turning to, because the wheel face of deflecting roller 2 is comparatively smooth, can do not towed by another steered wheel 21 (i.e. the steered wheel that contact with the wax crayon track) and skid so touch the steered wheel 22 of wax crayon track 5, thereby the phenomenon that car body can move along wax crayon track 5 occurs with desktop.If in like manner track 5 is to turn left, car body also will turn left along track.After the turning, car body will continue to advance according to track 5, until the next turning position place that runs to track 5.

In order to increase the interest of product, the utility model can coat the cladding 6 of a cartoon on car body frame 1.What for example adopted in the present embodiment is exactly the moulding of dog, certainly is designed to other moulding as required.
