Abstract
The utility model discloses a track racing car which comprises a car body, a car wheel drive transmission mechanism and a guide device. The car moves under the action the car wheel drive transmission mechanism. The track racing car is characterized in that the guide device comprises a track locking apparatus, a drive track locking apparatus rotating part and an energy storage spring. At least one track locking apparatus is installed on a chassis of the car body in a rotating mode; the upper end of one track locking apparatus is a rotating drive portion matched with the drive track locking apparatus rotating part, and the lower end of the track locking apparatus is provided with a pair of guide wheels which are clamped in T-shaped track grooves and can rotate; and the track locking apparatus is driven by the drive track locking apparatus rotating part and can rotates by 90 degrees, and when not being driven by the drive track locking apparatus rotating part, the track locking apparatus can rotate backwards by 90 degrees under the action of the spring. On the basis of driving on a traditional road surface, the track racing car has the advantages of self-locking the track, and being capable of avoiding a derailing phenomenon especially when turning and meanwhile automatically derailing after the car body is stricken by a car behind.
Description
Technical field
The utility model relates to a kind of track racing car, specifically a kind of track racing car with lock rail and automatic derailing function.
Background technology
The function mode of traditional track racing car is, slip when the chassis of track racing car downside is provided with the contact of downward extension, this slip cooperates with groove on the track, obtain electric energy, driving racing car moves, the speed of racing car is to be controlled by the variation of electric current, is that disclosed electric current mechanism for picking has just represented this mode among the CN14044008 as publication number.Common, we think that when track racing car turned to, because action of inertia, laterally offset or drift can take place vehicle body, and traditional guide finger easily comes off in groove.For preventing that track racing car from de-orbiting, generally be to be provided with a simple guide finger on the racing car chassis, be that disclosed guidance mode is exactly typical case representative among the CN14044008 as publication number, be the cooperation by guide finger and orbital groove realizes leading.Disclosed directive wheel design among the design of directive wheel such as the US publication US3016024A is also arranged, and is that the cooperation by directive wheel and orbital groove realizes leading.But no matter be guide finger or directive wheel, all have the problem that comes off easily, especially when turning around a curve, this possible shape that comes off increases especially greatly.
That is to say that the groove on traditional guide rail has two effects, one provides electric current, and another is to prevent derailing.
Another is self-powered track racing car, and for example Guangzhou Austria flies and overflows a kind of toy galloping car of design, adopts powered battery, and directive wheel and Ke Ka embrace and along the wheel of rail running on the car body, and make car body move along the track of circle.But the racing car of this kind structure need depend on self-designed cylindric track, and is different with traditional road surface racing car, broken away from the road surface, reduced the authenticity of recreation itself, reduced player's experience effect.
