Compared with the prior, the utility model has the advantages that since the one-way clutch is adopted, the electronic toy car is in four-wheel drive when moving forward, and is in rear-wheel drive when moving backward, so the player can switch different drive modes, thereby, the electronic toy car can bring about different feels when playing the toy car, and adds the enjoyment and playability for the electronic toy.

Description

Electric toy car

Technical field

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

Background technology

Existing electric toy car, the employing four-wheel drive that has, the employing two-wheel drive that has, but the electric toy car of four-wheel drive can't change type of drive, become two-wheel drive; And the electric toy car of two-wheel drive also can't change type of drive, becomes four-wheel drive, therefore lacks interest and playability.

Summary of the invention

The purpose of this utility model is that prior art is improved, and a kind of electric toy car is provided, and can change between four-wheel drive and two-wheel drive automatically, and the technical scheme of employing is as follows:

Electric toy car of the present utility model, comprise vehicle frame, be installed in two front vehicle wheels on the vehicle frame, two rear wheels, driving mechanism, control circuit, control circuit connects driving mechanism, driving mechanism connects two rear wheels by transmission mechanism, two rotating respectively preceding half section both sides of vehicle frame that are fixed on of front vehicle wheel, and connect by rotating shaft between two front vehicle wheels, it is characterized in that: in the described rotating shaft one-way clutch is installed, driving mechanism connects one-way clutch by transmission mechanism.

Described driving mechanism can drive front vehicle wheel by transmission mechanism, one-way clutch and rotating shaft and roll forward; When driving mechanism reversed, one-way clutch inner ring and outer ring broke away from automatically, so driving mechanism can't drive front vehicle wheel and rolls backwards.Above-mentioned front vehicle wheel rolls forward, just sees front vehicle wheel from the right side of electric toy car, and front vehicle wheel rotates counterclockwise; And front vehicle wheel rolls backwards, then is to see front vehicle wheel from the right side of electric toy car, and front vehicle wheel clockwise rotates.Like this, when the user controlled electric toy car and opens forward, electric toy car was four-wheel drive, and when the user controlled electric toy car and opens backwards, electric toy car was a two-wheel drive just.Different type of drive can be brought different game-play enjoyment.And, if increased steering mechanism, can also allow electric toy car realize drifting about curved, when the user controls electric toy car and opens forward, electric toy car is four-wheel drive, for electric toy car provides enough kinetic energy, when will controlling electric toy car, the user drifted about curved the time, driving mechanism quits work or reverses, and this moment, electric toy car became rear wheel drive, and therefore this moment, front vehicle wheel can keep earth-grasping force, steering mechanism drives front vehicle wheel and turns over suitable angle, just can allow the electric toy car whipping, electric toy car just can produce sideslip like this, thereby realizes the purpose that electric toy car drift about and bends.

A kind of fairly simple scheme, described one-way clutch adopts Ratcheting one-way clutch, comprises outer ring, inner ring, and inner ring is fixed in the rotating shaft, the outer sheathed ratchet of inner ring, the outer ring is rotating to be enclosed within the rotating shaft, and the outer ring medial surface is provided with at least one ratchet, and ratchet one end is rotating to be fixed on the medial surface of outer ring, the ratchet other end connects the outer ring inner peripheral surface by spring, ratchet and ratchet engaged, the outer ring outer circumference surface is provided with annular rack, and annular rack connects transmission mechanism.When the outer ring rotates counterclockwise, ratchet and ratchet engaged, drive ratchet, inner ring rotate counterclockwise; When the outer ring clockwise rotated, ratchet was pushed open by ratchet, can't drive ratchet, inner ring clockwise rotates, and the relative inner ring in outer ring clockwise rotates, and inner ring is motionless.More than counterclockwise, the judgement that clockwise rotates, all be to see one-way clutch from the right side of electric toy car, just be as the criterion and judge with the right view of electric toy car.

Another kind of scheme, described one-way clutch comprises outer shroud, interior ring, three pinions, gear wheel, interior ring is fixed in the rotating shaft, the interior ring side center relative with outer shroud is provided with reference column, gear wheel is fixed on the reference column lower semisection, the outer shroud outer circumference surface is provided with annular rack, the side that outer shroud is relative with interior ring has circular groove, the circular groove inner peripheral surface is provided with three projections, the center of outer shroud side has locating hole, outer shroud is by the rotating reference column upper semisection that is set in of locating hole, interior ring is positioned at circular groove, form the pinion locating slot between two adjacent projections, three pinions lay respectively in three pinion locating slots, and three pinions all mesh with gear wheel, three projections circumferentially evenly distributing along circular groove, each projection is provided with the non-return salient angle towards a side of gear wheel one end, and each projection is a curved surface towards the opposite side of gear wheel one end, and the non-return salient angle of each projection is corresponding with the curved surface of adjacent projections.

Described control circuit can be a remote control circuit, also can be the automatic control circuit of having set fixed routine.Remote control circuit is fit to bigger children or the adult uses, and has set the suitable less children use of automatic control circuit of fixed routine.

In order to protect the parts on the vehicle frame, also, the car shell is installed on the described vehicle frame in order to make electric toy car more attractive in appearance.

Described driving mechanism adopts direct current generator.

The utility model beneficial effect against existing technologies is, owing to adopted one-way clutch, when therefore electric toy car advances is four-wheel drive, become rear wheel drive when retreating, the user can change between different type of drive, can bring different game-play enjoyment to the user, increase the interest and the playability of electric toy car.
