Description

The working direction guide device of children toy car

Technical field

The utility model relates to a kind of working direction guide device of children toy car.

Background technology

In the toy for children, a kind of wheel is in the past arranged as the children toy car that turns to driving, in the fore wheel structure design of this kind children toy car, be that its front fork is pivoted behind the wheel body, making its front fork axostylus axostyle and vehicle frame front end be pivoted, so that wheel body can freely swing, then, be horizontally set with the leader in front fork axostylus axostyle upper end,, use the course that depends on children toy car to provide the user to grip to control the swaying direction of wheel body.

For the child when driving this kind children toy car, because development is incomplete as yet in child's the sense of equilibrium, so its directivity for the space has relatively poor induction force, therefore, the child has the dangerous thing of colliding to exist everywhere when controlling toy car and advance in fact, so, the general head of a family is when child's ride-on toy car, and initiatively band draws or passes toy car mostly, collides improperly and injures the child to prevent that toy car from having.

Yet the height of children toy car is limited, when adult of imposing stature when band draws or passes toy car, its certainly will will bend over action, and when the time of bending over to implement is oversize, for child's the head of a family, reality is the torment of a misery.

Inconvenience place that is had when drawing in the child head of a family for above-mentioned known children toy car, in the domestic utility model patent case, the structure design that No. 468507 " assistant steering device of perambulator " patent case of one bulletin arranged, improve to some extent with structure known thing, this patent case is mainly in the front fork axostylus axostyle place of perambulator front fork, be fixed with a vertical passive bevel type gear, and the back segment position of frame for baby cart, be pivoted with a vertical initiatively bevel type gear, and the drive shaft mount that makes two ends have horizontal bevel type gear is located at vertical passive bevel type gear and vertical initiatively between bevel type gear, and make each gear be meshed, so that a manual bull stick is when driving vertically initiatively bevel type gear rotation, with control perambulator direction of travel.

For the design of above-mentioned patent structure, be to make the child head of a family can control the direct of travel of perambulator easily, yet it is to have following shortcoming to exist in the drive mechanism mode of transmission shaft from the perambulator rear:

1, implement inconvenience: the structure of bevel type gear is implemented in when rotational force is converted to horizontal rotational force longitudinally, and its vectorial component will consume to some extent, and is comparatively painstaking in the feasible operation.

2, cost is higher: it certainly will be added with the more horizontal bevel type gear of enforcement part with the type of drive of transmission shaft, and so, its manufacturing cost improves naturally.

3, assembling inconvenience: its driving side with transmission shaft shows that making its complicated integral structureization has inconvenience to the assembling of perambulator and the reality of setting up of transmission shaft.

Summary of the invention

The purpose of this utility model is to provide a kind of working direction guide device of children toy car, this direction guide device makes on the preceding axle again of children toy car front fork, the sheathed negative pulley wheel that is fixed with, the back segment of toy for children vehicle carriage then is pivoted with a driving pulley, and negative pulley wheel and driving pulley are worn with a flute profile belt, so that one fixedly be connected when the control lever of driving pulley axle head is rotated, the working direction of may command children toy car, and its structure design is simplified, and the reduction of stack-mounted convenience and manufacturing cost is arranged.

The utility model is to provide a kind of working direction guide device of children toy car, this children toy car is pivoted with a front fork in its vehicle frame front end, and pivot joint for a front-wheel wheel body, the front fork axostylus axostyle upper end of front fork then is horizontally set with the leader, again, the vehicle frame rear end has the trailing wheel wheel body, and this guide device comprises a negative pulley wheel, before it wears and is fixed on not only the preceding but also axostylus axostyle; One driving pulley, it is articulated in vehicle frame back segment position; One flute profile belt, it is for wearing negative pulley wheel and driving pulley; One control lever, it is connected the axle head in driving pulley.

The utility model is also to provide a kind of working direction guide device of children toy car, and the terminal curved end of this control lever is a grip part.

The utility model can make the reduction of stack-mounted convenience and manufacturing cost.

The specific embodiment

Detailed read following detailed description and cooperate appended graphicly, can further understanding be arranged other purpose advantages of the present utility model and novel feature.

See also Fig. 1, shown in 2, children toy car 1 of the present utility model mainly has a vehicle frame 11, these vehicle frame 11 front ends have one and articulate pipe 111, be pivoted with the front fork axostylus axostyle 121 that a front fork 12 is provided, 12 of this front forks also are articulated with a front-wheel wheel body 13, both sides, vehicle frame 11 rear end then are provided with trailing wheel wheel body 14, so, so that children toy car 1 has the ability of walking, and and be horizontally set with leader 15 in front fork axostylus axostyle 121 upper ends, so that but rider's holds handle 15 is controlled the rotation direction of front fork 12, promptly the swaying direction of front-wheel wheel body is used the course that depends on this children toy car 1.

And the utility model is for the working direction correcting design of children toy car 1, be the front fork axostylus axostyle 121 hypomere positions that make front fork 12, the sheathed negative pulley wheel 2 with grinding tooth 21 that is installed with, place, vehicle frame 11 back segment top positions then has a drive-connecting shaft 112, and make this drive-connecting shaft 112 that being pivoted of driving pulley 3 with grinding tooth 31 is provided, and the axle head of this driving pulley 3 is the fixing enforcement that a control lever 4 is arranged that is connected, in addition, 3 of negative pulley wheel 2 and driving pulleys also wear with a flute profile belt 5, as shown in Figure 3.

By above-mentioned structure design, when the child drives children toy car 1, the child head of a family walks to turn the hand of rotation of control lever 4, so that driving pulley 3 drives negative pulley wheel 2 by flute profile belt 5, so that wear fixing front fork 12 under the rotation of control lever 4, the swing of isogonism is in the same way arranged, so with negative pulley wheel 2, the child head of a family can control the direction that toy car is advanced easily in children toy car 1 rear, as shown in Figure 4.

Be provided with down in structure of the present utility model, it is compared down with above-mentioned patent structure thing, and reality has the simplification of structure and can reduce manufacturing cost, and the convenience in the assembling is also arranged, and the utility model has the value of utilizing on progressive and the industry in fact.

On the structure design of the utility model for negative pulley wheel 2 and driving pulley 3, be to make it take turns body diameter one suitable arc angle to have a

baffle plate

22,32, and vehicle frame 11 articulates pipe 111 belows and drive-connecting shaft 112 a suitable arc angle place on every side, be to be provided with a block seat 113,114, so can limit the anglec of rotation of negative pulley wheel 2 and driving pulley 3, be the anglec of rotation of front fork 12, control lever 4, the swing of measuring angle arranged, and have the dangerous facts of overturning to take place to prevent front fork 12.

Again, control lever 4 bendable ends are a grip part 41, can be convenient to handle control lever 4 rotations.

In sum, the utility model studies at first through actual that new discovery gets for the inventor, and the utility model can have been reached the result of use of expection, and have practical value and progressive, therefore, the utility model should meet the application important document of novel patent, is to file an application.
