[0042] Specifically, the first drive member 3 is disposed at a position close to the middle of the first housing 1. The first transmission gear 41 is disposed at the middle part of the first housing 1 and is located below the first output gear 31.

[0043] The first drive member 3 is specifically a drive motor. The drive motor drives the first output gear 31 to rotate, thereby driving the eleventh transmission gear 41 to rotate, and further driving the two twelfth transmission gears 42, the two thirteenth transmission gears 43, and the two fourteenth transmission gears 44 to rotate, so as to drive the two first output shafts 2 to rotate.

[0044] The drive gearbox further includes a second housing 5, a first output wheel 22, a second output shaft 6, a second output wheel 62, and a second transmission assembly.

The first output shaft 2 can drive the second output shaft 6 to rotate through the second transmission assembly, and then make the output wheel rotate.

[0048] Wherein the second output wheel 62 is also the output wheel of the toy car. Both the first output wheel 22 and the second output wheel 62 are ordinary transverse wheels. At this time, four output wheels are provided on both sides of the toy car, that is, the toy car is an eight - wheel toy car.

[0049] Although the toy car in this embodiment is an eight - wheel toy car, this is not a limitation on the present utility model.

[0053] A fourth input gear 111 is provided on the third output gear 11, and the fourth input gear 111 meshes with the thirty-first transmission gear 91.

[0054] Specifically, the second driving member 8 is specifically a driving motor. The driving motor drives the fourth output gear 81 to rotate, and then drives the thirty-first transmission gear 91, the thirty-second transmission gear 92, the thirty-third transmission gear 93, the thirty-fourth transmission gear, and the thirty-fifth transmission gear 95 to rotate, so that the third output gear 11 rotates to drive the second housing 5 to rotate.

[0055] Third output gears 11 are provided at both ends of the driving gearbox, and the second driving member 8 is only in transmission connection with the third output gear 11 at the first end.

[0056] The two driving gearboxes are respectively a first driving gearbox and a second driving gearbox. The third output gear 11 at the first end of the first driving gearbox is connected to the third output gear 11 at the second end of the second driving gearbox through a connecting shaft, so that the second driving member 8 can drive the third output gear 11 at the first end and the third output gear 11 of another driving gearbox to rotate simultaneously. Thus, the two second housings 5 at one end of the toy car can rotate.

[0057] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
