[Technical Field]

The present invention relates to the field of toys and, more particularly, to a mad wheel. 【Background technique】

Some toy cars such as toy cars and crazy running wheels generally have two types of automatic control and wireless control. The wireless control is generally controlled by an infrared remote control. The remote control of a toy car such as a toy car or a mad running wheel has a built-in battery for power supply. Once the battery in the remote control is used up, it needs to be replaced, so you need to replace the battery frequently, which is more expensive.

I designed a crazy running wheel, including a car body and a remote controller for controlling the car body. The remote controller includes a USB connector and a plug connected to the computer and fixed in a box, and the car body includes an interface that is plugged into the plug. When the USB connector is connected to the computer, the battery in the car body and the remote control can be charged at the same time. The vehicle body comprises an upper shell, a lower shell and a gear box fixed by a limiting structure on the upper shell and the lower shell, the wheel further comprises a wheel and a driving motor connected through the gear box, the driving motor is fixed on the lower shell, and the output shaft of the driving motor A drive gear is fixed on the gearbox, and the gearbox is provided with a second gear that meshes with the drive gear. The gearbox further includes a first gear meshed by the transmission gear and the internal meshing gear of the wheel, thereby driving the drive motor to the wheel. This program is not public. Since the drive motor and the gearbox are separately fixed and fixed, the connection between the drive motor and the gearbox is not stabilized, and the drive gear on the drive motor and the second gear in the gearbox are not stably meshed.
