Description
The present invention relates to toy car, this toy car can surmount in same runway reposefully mutually.
For the toy car that travels is played at special-purpose racetrack, except that radio controlled toy car match, making some kinds of rules aspect runway design and the competition method, interfering with each other between match period before this to prevent many vehicles.Promptly as shown in figure 15, the runway of employing makes that the traveling lane 101 and 103 of toy car is separated from one another.Perhaps as shown in figure 16, make many toy vehicles from the relevant position start of a race spaced from each other, because this segment distance is arranged, a toy car is not easy to be caught up with in its back vehicle by another very much.
In recent years, a kind of method in back has become main flow.As shown in figure 16, adopt the runway of this method to make and can form single files sealing closed tracks by the runway grade separation part 105 that is formed on the endless track, clearly, this endless track can have many side by side traveling lanes each other.
Yet when adopting above-mentioned runway, even when beginning a toy car and toy car thereafter between separate suitable distance, if but the velocity contrast of two cars is very big, then vehicle is before running through by the predetermined number of turns of laws of the game, just back vehicle can catch up with the vehicle of front.In this case, because the width of conventional runway can only pass through a car well-to-doly, the car of back can not surpass the car of front.So just influence match.Therefore made laws of the game, regulation is in this case taken the car of front away run into the car of front from behind at the car of back before, and preceding vehicle is stood down.
In these cases, vehicle can be travelled side by side, then allow back vehicle to surmount the vehicle of front if increase the width of runway.Yet because conventional toy car lacks the driveability of keeping straight on forward, so if runway is widened, vehicle also may travel or backward going with zigzaggery.On the common runway with flat running ground, when along the negotiation of bends shown in Figure 17 (a), all vehicles travel along the runway outermost regions owing to be subjected to centrifugal action, so vehicle can not surpass the vehicle of front.
In addition, because the travel route of the travel route of a vehicle and other vehicle is consistent each other basically, so on conventional runway, be not easy to surmount very much preceding vehicle.Even back vehicle is had the honor parallel with the vehicle of front, shown in Figure 17 (b) and 17 (d), the recessed and ledge of front-wheel and trailing wheel and two car body both sides also may block each other.Vehicle is turn-taked or block runway.In this case, match just can not be carried out.
Therefore, the conventional toy car that travels on travelling except that with the radio controlled toy car, is difficult in the vehicle that surmounts the front in same the runway, and wherein reason is the shape of above-mentioned running rail and vehicle.Yet originate from real racetrack because of playing and for example originate from the Formula One match with toy car, wish also in this toy car match, can carry out surmounting of toy car so participate in the personal unconscious ground of toy car match, because this surmounting is unforgettable in the actual car match.The surmounting of carrying out of travelling side by side each other on the different runways that make this match seem separating with wall compared with two toy cars is more exciting surmounting on same the runway.Therefore a kind of surmounting to make player more enthusiasm and excitement before.
Therefore the objective of the invention is to improve the shape of toy car, this shape is to cause one of reason that conventional toy car can not surmount in play mutually, the present invention also aims to provide a kind of toy car that can steadily surmount another car on same runway that allows to surmount.
For achieving the above object, the invention provides a kind of toy car of running on track, this car longitudinally has elongated vehicle body.Support unit is configured in the front-end and back-end of vehicle body, with the supporting vehicle body.At least one is a driving wheel in the support unit.Vehicle body has very sharp head and very sharp afterbody.At least the both sides of vehicle body have level and smooth curved surface.The center of gravity of toy car be positioned at the driving wheel rotating shaft below.
Because vehicle body has very sharp head and very sharp afterbody, so when the head of back car was run into the afterbody of front car, this head or afterbody can be swung to the right or left, make head and afterbody to overlap in side direction.Subsequently, the car of back changes runway, and like this, the car of back just surmounts the car of front easily.
In addition because the both sides at least of vehicle body are level and smooth curved surface, so when the car of back when the side of front car surmounts, can prevent that two vehicle bodies from blocking each other.Can surmount stably thus.
In addition, because the center of gravity of toy car is lower than the driving wheel rotating shaft,, can steadily surmount so toy car can not overturn during travelling.
In addition, the invention provides a kind of toy car of running on track, this toy car has elongated vehicle body at longitudinal direction.Support unit is configured in the front-end and back-end of vehicle body, so that the supporting vehicle body.At least one in the support unit is driving wheel.Vehicle body has very sharp afterbody and is contained in the rotatable parts of its head.These rotatable parts can rotate when bumping against, thereby change the direction of head.At least the both sides of vehicle body have smooth surface.The center of gravity of toy car be positioned at the driving wheel rotating shaft below.
Because it is rotatable and change the rotatable parts of cephalad direction that the vehicle body head has when collision, so when the afterbody of the head of back car and front car bumped against, just rotated the rotation section of back car, the head change direction of car after this is feasible.Thereby, make the back appearance of vehicle easily surmount front truck.In addition, owing to there are rotatable parts, when the similar portions such as afterbody with front truck bumped against, rotatable parts came in contact resistance in the time of can absorbing collision, thereby can prevent that vehicle body is impaired.
On the toy car of above-mentioned running on track, the shape of cross section of vehicle body can make the toy car of running on track can recover its transport condition automatically when a rollover is fallen.
Because above-mentioned shape of cross section and toy car center of gravity are positioned at this feature below the live axle, even toy car overturns during travelling, this car itself also can erect automatically, as automatically reset tumbler, can return to its original state.Therefore unnecessary contest interruped.
In addition, the two supports parts all are to keep and the parts that can travel when running ground point contacts.
If adopt this support unit, then when side force acts on support unit, swing easily just have this part vehicle body of supporting part, thereby change the direction of vehicle body easily.If support unit is configured in the vehicle body head side, then when back car collision front truck afterbody,, thereby can easily change afterwards the car direction of travelling to the right just back headstock portion or swing left.Therefore the back car can surmount front truck at an easy rate.On the contrary, if support unit is contained in the rear side of vehicle body, then when the back car is run into the front truck afterbody,, so just form a space in the front of back headstock portion just the afterbody of front truck is swung backward or left.Thereby the back car is easy to surmount front truck.
In addition, the two supports parts all can be the balls around pivot axis.
In this case, when side force acts on the ball, the bottom of ball just on running surface to side slip, form aforesaid effect thus.
In addition, the two supports parts all can be balls, and this ball is dressed up to can freely rotating in any direction.
In this case, when lateral forces was on ball, ball is lateral rotation just.Thereby also can obtain aforesaid advantageous effects.In addition, the uneven part on the running ground also can change the travel direction of toy car.For example, on the surface of runway of travelling, form uneven part and also can make toy car, so just form a kind of novel motion that on routine is travelled runway, can not produce with respect to the travel direction lateral movement.Therefore toy car can produce infusive motion during travelling.
In addition, one of the two in the support unit can be the wheel that rotates in travel direction.This wheel has arcuate shape along the cross section that comprises the planar interception of wheel axle.
In addition, in the support unit the two one of can be rod-like members, this rod-like members is suitable for forming line with running surface and contacts.
In addition, one of the two in the support unit can be a kind of wheel, and this wheel can be swung to the right or left around pivot with respect to travel direction, and this wheel is positioned at the back of axis.
In this case, when lateral forces was on wheel, the swing of wheel can change steering angle, thereby can change the travel direction of vehicle body.In addition, thereby wheel is positioned at the back of pivot, so when toy car to overtake the time, wheel itself can forward the direction of keeping straight on forward to.When outer side when masterpiece is used for vehicle body, this wheel can automatically make vehicle body forward to break away from the direction of external force effect.

Below with reference to the description of drawings embodiments of the invention.Fig. 1 is the perspective view of the running on track toy car 1 of the present invention seen from above.This running on track toy car 1 has elongated whole vehicle body 3 for the smooth surface formation.Vehicle body 3 has the very sharp head 5 that forms at its front end.Very sharp afterbody 7 is formed on the rear end of vehicle body 3.Vehicle body 3 has level and smooth curved surface in its both sides, thereby in motion when wipe each other mutually the side of car, two toy cars can surmount mutually reposefully, can not block side each other.
Fig. 2 is the perspective view of the toy car 1 seen from the bottom.Fig. 3 is the preceding figure of toy car 1.Fig. 4 is a side view, and the internal structure of toy car 1 is shown, and Fig. 6 and 7 is perspective views, and the drive system that is applied on the toy car 1 is shown.
As shown in Figure 2, the rear end part of toy car 1 has two driving wheels 9.This driving wheel 9 is by the drive force of motor 11, and this motor configurations is at the front end of vehicle body 3.This driving force transmits by transmission system.Motor 11 is driven by the battery 13 that is contained in vehicle body 3 central interior substantially.Power supply to motor 11 can switch on and off by switch 15.
Reach the drive system of driving wheel 9 from motor 11 below with reference to Fig. 4,6 and 7 explanations.Pinion 12 is contained on the output shaft of motor 11.This pinion 12 and first gear, 18 engagements that are contained in rotating shaft 19 1 ends.Second gear 21 is contained on the other end of this rotating shaft 19.Second gear 21 and idler gear 23 engagements.This idler gear 23 and ring gear 25 engagements, these ring gear 25 fixed configurations are on the axle 17 of driving wheel 9.
In drive system, when motor 11 rotated, rotating shaft 19 was rotated, and the rotation of rotating shaft 19 is sent to ring gear 25 by idler gear 23, thereby wheels 9 is rotated.
On toy car 1 of the present invention, the fore-end of vehicle body 3 is by the support unit supporting with peculiar structure.Promptly shown in Fig. 2 and 5, at the downside front-end configuration ball 27 of toy car 1.This ball is supported to and can freely rotates in any direction.Therefore when be subjected in addition during very slight lateral forces this head 5 also can be easily to the right or turn left.
Though in this embodiment, ball can rotate in any direction, and ball 27 also can become the pivot axis of only extending perpendicular to toy car 1 y direction around an edge in travel direction.Perhaps ball 27 can be configured to fixed state, makes it not rotate.Even be configured to and rotate or during fixed configurations, to contact in travel direction, so head 5 is being subjected to even also can easily swinging to the right or left during slight lateral forces because ball 27 forms point with the surface of driving runway at ball 27.
Because the back toy car 1 during travelling on the driving runway surmounts under the situation of front toy car 1 from behind, head 5 is sideshake easily, so the head 5 of toy car 1 is run into after the afterbody 7 of front toy car in the back, the head 5 of front toy car 1 can be swung to the right or left; Make back toy car 1 change its direction.Therefore back toy car 1 can surmount front toy car 1 from the side, goes to its front.
Fig. 8 (a) illustrates other example of supporting member to Fig. 8 (c), and as mentioned above, these supporting members are done as far as possible for a short time with driving runway surface contact area.Fig. 8 (a) illustrates the example of making support unit with wheel.In this example, wheel 31 is by the base rotatably support.This wheel 31 can rotate around the axle (not shown) in the travel direction of toy car 1.Shown in Fig. 8 (a), the surface 33 of wheel is a convexity, thus wheel 31 it is shaped as arc along the cross section of the planar interception that comprises axle.Therefore in this embodiment, when head 5 was subjected to quite little lateral forces, this head 5 also can easily be swung to the right or left.
Fig. 8 (b) illustrates the support unit of sledge shape.The cross section flatly is connected in the downside of underframe 35 for circular shaft-like supporting member 37.The part 39 that is bent upwards is formed on the far-end (i.e. front end when the travel direction of toy car 1 is seen) of rod-like element 37.This underframe 35 is connected in the downside of vehicle body 3 rotationally.Perhaps, underframe 35 can be fixedly connected on the downside of vehicle body 3.The supporting member of Xing Chenging is in the lower surface and the runway surface formation line state of contact of rod like parts 37 thus.When being subjected to lateral forces, head 5 is easily swung to the right or left because of its contact area is minimum.
Fig. 8 (c) illustrates the embodiment that only changes head part 5 embodiment illustrated in fig. 1.In this embodiment, be configured in the front end of head 5 as the rotatable roller 41 of rotatable parts, this roller is rotatable when collision, thereby changes the direction of head 5.Pivot 43 is contained in the back of roller 41.This pivot 43 extends perpendicular to driving runway surface.Tilting member 45 is connected in pivot 43 rotationally, extends in the back of this pivot, thereby can rotate around pivot 43.Tilting member 45 has the narrow of castor type and takes turns 47.Roller 41 also can be with tilting member 45 around pivot 43 swings.Should be noted that roller 41 can be configured to not swing.The outer peripheral portion of roller 41 is equipped with for example rubber of elastomeric material, and is impaired because of collision to prevent vehicle body 3.
In this embodiment, toy car 1 surmounts under the situation of front toy car 1 from behind in the back, and the roller 41 that is contained in toy car 1 head 5 is at first run into the afterbody 7 of front toy car 1.This moment roller 41 rotations and swing, and wheel 47 is also swung with roller.As a result, make of right side or the left side swing of the head 5 of back toy car 1 to front toy car 1 afterbody.Thereby the toy car 1 of front is easy to surmount front toy car 1.
Though present embodiment has been united two kinds of parts, promptly rotatable and the roller 41 that can swing and the wheel 47 that can swing should be noted that the running on track toy car can have only parts in two parts.That is,, head 5 is swung easily when running into the front toy car to the right or left, be reached the such advantageous effects of its direction of change even the running on track toy car has only any member in two kinds of peculiar members.
For example, as the remodeling of Fig. 8 (c) illustrated embodiment, can be configurable on the position that is positioned at pivot 43 back of vehicle body 3 one sides around the roller 41 of pivot 43 swing, rather than be configured in the front end of vehicle body 3.When adopting this configuration, wheel 47 can respond roller 41 and another toy car or contacting of similar object and change its direction.Therefore toy car can move in the mode that stops the external force effect.So just, cause above-mentioned advantageous effects.
When many toy cars travel in same runway, run into second car as the roller 41 of first car, just first car moves, driving to second car as it.Therefore first car is for people's impression, and it is attacking second car.So just, produce the effect that war takes place vehicle each other.
Though the structure of running on track toy car of the present invention has been described above, the present invention not necessarily is limited to said structure.Driving wheel 9 can also be configured in the front end of toy car among the present invention, and with support unit for example ball 27, wheel 31, rod-like members 37 or take turns 47 rearward end that fit over toy car.One in front and one in back travel and the car of back surmounts under the situation of front car at two toy cars, when the head 5 of back car is run into the afterbody 7 of front car, will make afterbody 7 swings of front car with this structure.Thereby the direction of change front car.Like this, the back car just is easy to surmount the front car.Can also drive support unit for example ball 27, wheel 31, rod-like members 37 or take turns 47.
The following describes the operation of running on track toy car.Running on track toy car of the present invention can for example travel or compete on the endless track at the runway of sealing.Yet, the running on track toy car is for example travelled having the curved section shape in the runway 55 of the arc section shape shown in Fig. 9 (a)～9 (c) in order further to cause player's interest.
Have under the situation of travelling on the runway 55 of curved section shape aforesaid at running on track toy car 1, can be just like the driving mode shown in Fig. 9 (a)～9 (c).Fig. 9 (a) illustrates the mode that toy car 1 travels on the approximate straight way part of runway 55.In this case, toy car 1 travels on the part of travelling of lowermost portion.Fig. 9 (b) illustrates the mode that toy car 1 partly travels at bend, and in this case, the position that toy car 1 travels on running surface is determined by the effect centrifugal force 51 and the resultant direction of gravity 53 onboard.For example be subjected to centrifugal action because of certain reason during Fig. 9 (c) is illustrated in and travels or meet the situation that other toy vehicles car 1 has fallen to a rollover.In this case, because the center of gravity of toy car 1 is lower than rotation shaft of wheel, and as shown in Figure 3, the cross sectional shape of toy car 1 makes toy car 1 itself be easy to erect when upset, so toy car 1 itself can automatically erect as tumbler, shown in the arrow among the figure.
The various patterns that surmount between these two toy cars when illustrating that below with reference to Figure 10 (a)～14 (d) two running on track toy cars of the present invention travel on same runway 55.Each runway shown in Figure 10 (a)～14 (d) has the semicircular sectional shape shown in Fig. 9 (a)～9 (c), can evoke the match that the player more excitedly drops into toy car 1 of the present invention like this.Should be noted that the runway that travels that is used for running on track toy car 1 of the present invention not necessarily is limited to the runway with semicircular sectional shape.Can also use any other runway that travels, on these runways, no matter running on track toy car 1 also can surmount another car and the what state of the aspects such as planar configuration of the cross sectional shape of runway and runway.In the following description, say the toy car of " back vehicle " to represent before surmounting, and say the toy car of " preceding vehicle " to represent with numbering 1b with numbering 1a.
Figure 10 (a)～10 (d) and Figure 11 (a)～11 (d) are illustrated in the mode that back vehicle 1a on the straightaway surmounts preceding vehicle 1b.In Figure 10 (a), two toy cars are that the extreme lower position of semicircular runway 55 is travelled at cross sectional shape.In Figure 10 (b), the head 5 of back car 1a is run into the afterbody 7 of front car 1b.At this moment, because supporting member has said structure, the head 5 of back car 1a rotates to the direction shown in the arrow 57 easily.
Shown in Figure 10 (c), back car 1a climbs up the curved surface of runway 55, changes its direction left subsequently, travels side by side with preceding vehicle 1b subsequently.At this moment, the power that acts on the car 1a of back makes this back vehicle be pushed the lowermost part of getting back to runway 55 curved surfaces.Thereby back car 1a pushes away the afterbody 7 of front car 1b to the right, and is as shown in arrow 59.At last, shown in Figure 10 (d), back car 1a goes to the front of front car 1b.Get back to the state that travels in semicircle runway 55 its lowermost position with latter two car.
Figure 11 (a)～11 (d) illustrates as back car 1a and knocks front car 1b, promptly is not the leading mode shown in Figure 10 (a)～10 (d) when running into afterbody 7, and the afterbody 7 of back car 1b just rotates.In this case, the afterbody 7 of front car 1b is swung to the right when collision, and is as shown in arrow 61.Subsequently, shown in Figure 11 (c), back car 1a is almost along straight ahead, and car 1b pushes away to the right with the front.Last shown in Figure 11 (d), back car 1a goes to the front of front car 1b.Then, two cars are got back to the state that travels at semicircle runway 55 lowermost parts.
It is the mode that the bend of semicircular runway 55 partly surmounts front car 1b at cross sectional shape that Figure 12 (a)～12 (b), Figure 13 (a)～13 (d) and Figure 14 (a)～14 (d) illustrate back car 1a.In Figure 12 (a), two cars travel along runway 55, are subjected to the effect of centrifugal force 63 simultaneously, and this centrifugal force trends towards to the extrapolation toy car.Figure 12 (b) illustrates back car 1a and knocks front car 1b, and the head 5 that makes back car 1a is to the inner swing of crooked runway.Subsequently, shown in Figure 12 (c), back car 1a and front car 1b travel side by side, and back car 1a pushes front car 1b to the outside along the flexure plane of runway 55 with centrifugal force 63.Because front car 1b travels in the outside of runway 55, so the operating range of front car 1b is corresponding longer, car 1b in front just enters unfavoured state all the more like this.Last shown in Figure 12 (d), back car 1a goes to the front of front car 1b, along a quite desirable route running.
Figure 13 (a)～13 (d) illustrates back car 1a and knocks front car 1b, makes the head 5 of back car 1a be flapped toward the state in runway 55 outsides.In this case, car 1a in back travels in the outside of car 1b in front.So the distance that back car 1a travels is corresponding longer.Like this, back car 1a just can not surmount front car 1b, removes not sum front car 1b and compares, and it travels with much bigger speed.Thereby under normal circumstances, two cars crosses the bend part together, makes that the head 5 of back car 1a is arranged side by side with the afterbody 7 of front car 1b, shown in Figure 13 (b)～13 (d).Back car 1a is on the straight way of subsequently runway 55 or just go to the front of front car 1b on subsequently its bending direction bend opposite with existing bending direction.
The travel speed that Figure 14 (a)～14 (d) illustrates back car 1a is significantly greater than the situation of front car 1b travel speed.In this case, act on centrifugal force 63 on the car 1a of back greater than the centrifugal force 63 that acts on the car 1b of front.Therefore on bend, back car 1a can be that the higher position of semicircular runway 55 surmounts in the cross section.Shown in Figure 14 (b)～14 (d), two cars travels along different travel routes in this case, and the car 1a of back can go to the front of front car 1b under the situation of not running into the front car.
Should be noted that the present invention not necessarily is limited to the foregoing description, can change by different way and do not deviate from spirit of the present invention.
