Abstract
The utility model discloses a steering wheel capable of returning automatically. The steering wheel capable of returning automatically comprises a steering wheel body, and the steering wheel body is connected with a self-return device through a steering yoke. The self-return device comprises an upper cover and a bottom plate, a hole seat is arranged in the middle of the bottom plate, a hollow cylinder capable of rotating is arranged in the hole seat, two symmetrical return sheets extend outwards from the outer surface of the hollow cylinder, a first screw is arranged on the end portion of one of the return sheets, a second screw is arranged on the end portion of the other return sheet, the middle portions of two edges, corresponding to each other, of the bottom plate are provided with a third screw and a fourth screw respectively, the first screw is connected with the third screw through a first spring, the third screw is connected with the second screw through a second spring, the second screw is connected with the fourth screw through a third spring, and the fourth screw is connected with the first screw through a fourth spring. When the steering wheel is controlled to turn, the hollow cylinder connected with the steering wheel rotates to enable a vehicle to turn; and when the steering wheel is loosened, the steering wheel returns because the hollow cylinder is stressed by elastic force and pulling force of the springs.
Description
Technical field
The utility model relates to children's electric children vehicle, but particularly a kind of bearing circle that is used for the self-return of children's electric children vehicle.
Background technology
At present, the bearing circle of existing children's electric motor vehicle all is that the direction of passage bar directly is connected with the cross bar of front-wheel, after turning, car needs with artificial or remote controller operation return, the inconvenience when operator operates, be difficult to make the car location to keep straight on, the easy wigwag motion of car brings the scaring of double swerve for the child who is sitting on the car.
The utility model content
The purpose of this utility model is, at the above-mentioned defective of prior art, but provides a kind of bearing circle of self-return of the children's of being used for electric children vehicle.
For solving the above-mentioned deficiency of prior art, technical scheme to be solved in the utility model is: but a kind of bearing circle of self-return, comprise a bearing circle, described bearing circle direction of passage bar is connected with automatic resetting device, described automatic resetting device comprises loam cake and base plate, described base plate middle part is provided with a hole seat, described hole seat is provided with a rotating hollow cylinder, the through hole of the corresponding loam cake of the other end of described hollow cylinder stretches out, the outside face of described hollow cylinder extends outward two symmetrical return sheets, the end of one of them return sheet is provided with first screw, the end of another one return sheet is provided with second screw, middle part, the corresponding both sides of described base plate is respectively equipped with the 3rd screw, the 4th screw, described first screw is connected by first spring with described the 3rd screw, described the 3rd screw is connected by second spring with described second screw, described second screw is connected by the 3rd spring with described the 4th screw, described the 4th screw is connected by the 4th spring with described first screw, described first spring, second spring, the 3rd spring and the 4th spring surround a rectangle.
But as a kind of improvement of the bearing circle of the utility model self-return, the end that the through hole of the corresponding loam cake of described hollow cylinder stretches out is provided with and direction lever bonded assembly pin hole.Pin hole helps being connected of direction lever and hollow cylinder, in the time will keeping in repair and change to returning device, and easy disassembly.
But as a kind of improvement of the bearing circle of the utility model self-return, described first spring, second spring, the 3rd spring are identical with the specification of the 4th spring.First spring, second spring, the 3rd spring are identical with the specification of the 4th spring, and what each that makes the return sheet was subjected to force direction is subjected to force intensity identical, and each that guarantee the return sheet is subjected to force direction to keep balance.
Compared with prior art, the utility model has the advantages that: the utility model adopts bearing circle to be connected with automatic resetting device, realize the revert action of car by first spring in the automatic resetting device, second spring, the 3rd spring and the 4th spring, when the control bearing circle is turned, rotate with bearing circle bonded assembly hollow cylinder, car is turned.When unclamping bearing circle,, make car fixing along straight-line travelling because hollow cylinder is subjected to the effect of spring force and pulling force to make return sheet return.The utility model is simple in structure, processing ease, simple and convenient assembly, advantage such as safe in utilization.
Description of drawings
