Description

Technical Field

[0001] The utility model relates to the technical field of toys, and more specifically, to a toy car capable of preventing from falling. Background Art

[0002] With the advancement of science and technology and the improvement of people's living standards, the types and functions of toys are becoming increasingly rich. Among them, toy cars are deeply loved by children because of their easy operation and diverse shapes. Traditional toy cars, such as remote control cars and electric cars, usually only have simple straight or turning functions and cannot adapt to complex ground environments. Especially when facing suspended ground such as table tops, they are prone to falling, causing damage to the toys or creating safety hazards.

[0003] In recent years, in order to solve this problem, some toy cars with anti-falling functions have appeared on the market. These toy cars are equipped with sensors or mechanical structures to detect and prevent falling from the suspended ground. However, these toy cars are often complex in structure, high in manufacturing cost, and difficult for children to operate and maintain.

[0004] In addition, some toy cars try to avoid falling by changing the driving route. For example, the toy car with switchable routes mentioned in the prior art (Chinese invention patent: A toy car with switchable routes, publication number: CN112190961A) controls the power transmission between the drive gear box and the steering link to switch the toy car from an S-shaped route to a straight route. Although this method improves the adaptability of the toy car to a certain extent, it still has the problem of insufficient adaptability to specific road conditions, especially when facing a suspended ground, it still cannot effectively avoid falling.

[0005] Therefore, how to design a toy car with a simple structure, easy operation and the ability to effectively prevent it from falling from the suspended ground has become a problem to be solved urgently in the current toy car technical field. Utility Model Content

[0006] The main purpose of the utility model is to achieve automatic steering of the toy car when it faces the suspended ground through a simple and effective mechanical structure, so as to prevent it from falling, in view of the above defects and shortcomings.

[0007] In order to achieve the above purpose, the specific technical solution adopted by the utility model is:

[0009] The power device is installed on the chassis, and includes a driver, a first transmission gear set, and a second transmission gear set. The wheels are transmission-connected to the driver through the first transmission gear set.

[0010] The anti-falling toy car also includes a steering wheel, which is drivably connected to the driver through a second transmission gear set, and the axis around which the steering wheel rotates is perpendicular to the axis around which the wheel rotates. The steering wheel passes through the chassis and is exposed at the bottom of the chassis, and the radius of the steering wheel is smaller than the radius of the wheel, so that in a normal running state, when the wheel contacts the ground, a gap is left between the steering wheel and the ground.

[0011] Preferably, the second transmission gear set is connected to the steering wheel via a linkage shaft.

[0012] Preferably, the chassis is provided with a wheel groove, and the steering wheel passes through the wheel groove and is exposed at the bottom of the chassis.

[0013] Preferably, the wheels include front wheels and rear wheels.

[0014] Preferably, the rear wheel comprises two wheel hubs and a wheel axle, the wheel axle is provided with a bevel gear, and the bevel gear is meshingly connected with the first transmission gear set.

[0015] Preferably, a mounting groove is provided on the chassis, and the driver is mounted on the mounting groove.

[0016] Preferably, the anti-fall toy car comprises a shell, and the shell and the chassis are fixedly connected by bolts.

[0017] Preferably, the housing is configured in a sedan shape, a truck shape or a sports car shape.

[0018] Preferably, the driver is configured as a stepper motor.

[0019] Preferably, a battery compartment is provided on the chassis, and batteries are installed in the battery compartment.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] In the utility model, when the toy car encounters a road condition with a suspended ground in front, the wheels are first suspended in the air. At this time, the steering wheel will come into contact with the ground, and the steering wheel will play a role in changing the forward direction of the toy car, so that the toy car turns around; after turning around, when the toy car re-enters the ground without suspension, the wheels come into contact with the ground again, and a gap is formed between the steering wheel and the ground again, and normal running is resumed; thereby, the toy car can be prevented from falling in the case of a suspended ground.
