Abstract

A toy used steering mechanism comprises a toy main body, a steering motor, a steering gear group, a left and right two-steering direction cup , a left and right two steering wheel equipped on each steering cup, and a steering bar which connects two steering wheels and is connected with the bottom degree steering gear, characterized in that the utility model also comprises a potentiometer the resistance value of which can change with the rotation, wherein the potentiometer and a second steering gear are coaxially equipped on the toy main body, the resistance output end is connected with a steering control device on a wire board and feedbacks and controls the rotation of a steering motor. Since the utility model smartly adds the structure of the potentiometer with the resistance value variable which can feedback and control the rotation of the steering motor to the prior steering mechanism, on the base of ensuring that the utility model has the advantages of the past steering mechanism, the utility model can also reliably feedback and control the rotation of the steering motor through the potentiometer to precisely control the steering angle of the two steering wheel, thereby further increasing the interest of players, and the structure is simple, the assembly is easy, and the practicability is strong.

Description

A kind of toy steering mechanism

Technical field

The utility model relates to a kind of toy steering mechanism, the automobile-used foresteerage gear of particularly a kind of remote-control toy.

Background technology

Existing toy car foresteerage gear is varied, as Chinese patent CN1141814A, CN2474202Y and U.S. Pat 5722873A disclose a kind of direction-changing device respectively, remote-controlled toy vehicle and the steering mechanism on the toy car chassis (RADIO-CONTROLLED TOY CAR WITH ANIMPROVED STEERING SYSTEM) with speed upgrading, its primary structure all is to reach the conversion of controlling the direction of two front-wheels with tooth sector group that is connected with steer motor and turning-bar by the steer motor that is controlled by the steering control device on the wiring board (PCB), but the transfer of above-mentioned these several structures all can not be by the action of its deflecting roller the FEEDBACK CONTROL steer motor accurately controlling the steering angle accurately of two deflecting rollers, not only influenced the interest of playing that turns to precision but also influence the toy person of toy car.

Summary of the invention

The purpose of this utility model is the problem at above-mentioned existence, provide a kind of can be on the basis of original toy car steering mechanism can be effectively by turning to of deflecting roller turning to of FEEDBACK CONTROL steer motor and accurately control the toy steering mechanism of the steering angle of two deflecting rollers.

The technical solution of the utility model is achieved in that

A kind of toy steering mechanism, comprise the toy main body, the steer motor of device in the toy main body and the tooth sector group that is connected with motor output shaft, about two turn to cup and device respectively turn on the cup can be with two deflecting rollers about turning to respectively that cup rotates synchronously, connect two turning-bars that turn to cup and be connected with the final stage tooth sector of tooth sector group, wherein respectively turn to cup can install rotationally in the toy main body around an axle that is nested with in the toy main body respectively, fork on the final stage gear of the middle part of turning-bar and tooth sector group is connected, its two ends respectively with two turn to cup to be connected also can to drive two-wheeled to cup around its rotation, be characterized in also including the potentiometer that a resistance can change with the rotation of deflecting roller, this potentiometer is installed on the toy main body with the secondary tooth sector of tooth sector group is coaxial, and the steering control device that its resistance output rotates by the control steer motor on electric wire and the wiring board is connected the also rotation of FEEDBACK CONTROL steer motor.

But the utility model is owing to increase the structure of resistance potentiometer that can change with the rotation of deflecting roller and the FEEDBACK CONTROL steer motor dexterously in existing steering mechanism, guaranteeing that the utility model has on the basis of advantage of original steering mechanism, can also accurately control the steering angle of two deflecting rollers reliably by coming the FEEDBACK CONTROL steer motor with the synchronous potentiometer that rotates of the secondary tooth sector of tooth sector group, thereby further improve the interest of player, and it is simple in structure, assembling is easy, practical.

Describe basic structure of the present utility model and operation principle in detail below in conjunction with accompanying drawing:

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the utility model is applied in the structural representation on the toy car;

The specific embodiment

As Fig. 1～shown in Figure 2, the utility model comprises toy main body 1, the steer motor 2 of device in toy main body 1 reaches the tooth sector group 3 that is connected with steer motor 2 output shafts, about two turn to cup 4 and device respectively turn to cup on 4 can be with two deflecting rollers 5 about turning to respectively that cup 4 rotates synchronously, connect two turning-bars 6 that turn to cup 4 and be connected with the final stage tooth sector 33 of tooth sector group 3, wherein respectively turn to cup 4 can install rotationally in toy main body 1 around an axle 41 that is nested with in toy main body 1 respectively, fork 331 on the final stage gear 33 of the middle part of turning-bar 6 and tooth sector group 3 is connected, its two ends turn to cup 4 to be connected with two respectively and can drive two-wheeled and rotate around its axle 41 to cup 4, be characterized in also including the potentiometer 7 that a resistance can change with the rotation of deflecting roller 5, secondary tooth sector 32 coaxial being installed on the toy main body 1 of this potentiometer 7 and tooth sector group 3, the steering control device that its resistance output rotates by the control steer motor on electric wire and the wiring board 2 is connected the also rotation of FEEDBACK CONTROL steer motor.Like this when steer motor 2 rotations, the primary pinion group 31 that can drive tooth sector group 3 is rotated, driving its secondary tooth sector 32 after slowing down rotates, secondary tooth sector 32 rotates potentiometer 7 by its rotating shaft synchronously, secondary tooth sector 32 also drives 33 rotations of final stage tooth sector simultaneously, the fork 331 of final stage tooth sector 33 can drive turning-bar 6 and move, during turning-bar 6 move left and right, it is the center rotation with the axle 41 of device in the toy main body that drive turns to cup 4, thereby driving two deflecting rollers 5 swings, the purpose that realization turns to, the rotation of potentiometer 7 simultaneously changes its resistance, feed back to the working time that steering control device on the wiring board (PCB) is controlled steer motor 2 by electric wire, promptly steering control device is determined the angle of two deflecting rollers, 5 swings according to the size of change in resistance.
