Description

A rolling toy car

technical field

This field relates to the field of toy cars, in particular to a rolling toy car.

Background technique

There are many toys on the market whose design inspiration comes from life, such as toy cars and toy guns. As a relatively common children's toy, toy cars are generally loved by children because of their mobility. In order to improve the fun of toy cars, many manufacturers change the appearance of toy cars or the internal driving mechanism to make toy cars look more beautiful and can move forward and backward to attract consumers.

The traditional toy car structure is to place the steering mechanism at the front of the car, the driving mechanism at the rear of the car, and the battery in the middle of the car. The toy car with this structure is inflexible, not very interesting, and the assembly process is cumbersome. Substandard products are prone to occur, and the driving mechanism and steering mechanism lack necessary protection measures, are easily damaged, and have a high repair rate, which increases production costs.

In view of this, it is necessary to study a rolling toy car whose structure should be simple and reasonable, can effectively realize the rolling action of the toy car, and is easy to process and not easy to damage the internal structure.

Contents of the invention

In order to solve the problems of unreasonable structure, inflexible driving, high cost and lack of interest of the toy car, the specific technical solutions provided by the present invention are as follows:

A rolling toy car, including a vehicle frame, front wheels and rear wheels, it also includes a driving mechanism, a steering mechanism, a battery box and a soft leather wheel, the driving mechanism drives the rear wheels to rotate, the steering mechanism drives the front wheels to turn, the driving mechanism, the steering The mechanism is arranged on the left side of the rear wheel, the battery box is arranged on the right side of the rear wheel, and the outer peripheral side of the rear wheel is sleeved with a barrel-shaped soft leather wheel. One-piece structure and set at the rear of the frame.

The drive mechanism includes a drive motor and a drive tooth box, the output shaft of the drive motor is connected to the drive tooth box, and the drive tooth box is connected to the central shaft of the rear wheel.

The steering mechanism includes a steering motor, a steering tooth box and a steering tie rod. The output shaft of the steering motor is connected to the steering tooth box, the steering tooth box is connected to the steering tie rod, and the steering tie rod is connected to the front wheels.

As a preferred solution of the present invention, the diameters at both ends of the buff wheel are smaller than the diameter at the middle.

As a preferred solution of the present invention, the outer periphery of the soft leather wheel is provided with horn-shaped patterns to increase friction.

As a preferred solution of the present invention, a rear wheel alignment frame is provided on the side of the battery box.

As a preferred solution of the present invention, the toy car is also provided with a control circuit board.

As a preferred solution of the present invention, a return torsion spring is provided at the joint between the steering tie rod and the front wheel.

As a preferred solution of the present invention, the frame includes a left frame and a right frame.

Beneficial effects of the present invention: the toy car of the present invention is reasonable in structure and ingenious in design, and the soft leather wheel integrates the rear wheel, driving mechanism, steering mechanism, and battery box and is arranged behind the frame, which is easy to assemble and soft leather wheel The internal structure is protected, the production process is reduced, and the production cost is reduced. At the same time, the center of gravity of the car is located at the rear. When the car is moving forward at high speed, the steering of the driving motor of the driving mechanism is changed through the control circuit board. The toy car is under the action of huge torque. Down, a 180-degree rollover occurs, the original upper surface of the car becomes the lower bottom surface, and the lower bottom surface becomes the upper surface, which increases the fun and avoids the boring feeling of the user. The steering mechanism changes the forward direction of the front wheels through the steering rod. The toy car can be turned flexibly. In addition, the diameters of the two ends of the soft leather wheel are smaller than the diameter of the middle part, which is beneficial to the rolling of the car.

detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:

As shown in Fig. 1 and Fig. 2, a kind of rolling toy car comprises vehicle frame 1, front wheel 2 and rear wheel 3, and vehicle frame 1 comprises left vehicle frame 11 and right vehicle frame 12, and toy vehicle also comprises driving mechanism 4, Steering mechanism 5, battery box 6 and soft leather wheel 7, driving mechanism 4 drives rear wheel 3 to rotate, and steering mechanism 5 drives front-wheel 2 to turn, and driving mechanism 4, steering mechanism 5 are arranged on the left side of rear wheel 3, and battery box 8 It is arranged on the right side of the rear wheel 3, and the outer peripheral side of the rear wheel 3 is sleeved with a barrel-shaped soft-skinned wheel 7. The soft-skinned wheel 7 integrates the rear wheel 3, the driving mechanism 4, the steering mechanism 5, and the battery box 6 into an integrated structure. Be arranged on the rear of the vehicle frame 1, the outer circumference of the bum wheel 7 is provided with a castellated pattern that increases friction, and the bum wheel 7 has a buffering and protective effect.

As shown in Figure 3, described driving mechanism 4 comprises drive motor 41 and drive tooth box 42, the output shaft of drive motor 41 is connected to drive tooth box 42, is provided with the gear set that meshes with each other in the drive tooth box 42, drives tooth box 42 Connect the central axis of trailing wheel 3, and trailing wheel 3 rotates and is installed on the trailing wheel spacer of battery case 6 sides. When the drive motor 41 rotates, the drive tooth box 42 drives the rear wheel 3 to rotate, supplying the power that the toy car advances.

The steering mechanism 5 includes a steering motor 51, a steering gear box 52 and a steering pull rod 53, the output shaft of the steering motor 51 is connected to the steering gear box 52, and the steering gear box 52 is provided with a gear set that meshes with each other, and the steering gear box 52 is connected to the steering gear box 52.
