[0036] As Figures 1-5 shown, this embodiment discloses a toy car, which includes a toy car drive gearbox and a car body. The drive gearbox is arranged on the car body. The drive gearbox includes two sub-gearboxes arranged axially symmetrically. The sub-gearbox includes a first housing 1, two first output shafts 2 and two first driving members 3.

[0037] The two first output shafts 2 are respectively rotatably arranged at both ends of the first housing 1 and partially exposed outside the first housing 1.

[0038] The first driving member 3 is arranged on the first housing 1. Specifically, a first accommodation chamber is arranged on the first housing 1, and the first driving member 3 is arranged in the first accommodation chamber.

[0039] The two first driving members 3 are respectively in transmission connection with the two first output shafts 2 for driving the first output shafts 2 to rotate.

[0040] The first driving member 3 at the first end is in transmission connection with the first output shaft 2 at the first end through a first transmission assembly; the first driving member 3 at the second end is in transmission connection with the first output shaft 2 at the second end through a fourth transmission assembly.

[0041] Specifically, a first output gear 31 is arranged at the output end of the first driving member 3, and a first input gear 21 is arranged on the first output shaft 2.

[0042] The first transmission assembly includes an eleventh transmission gear 411, a twelfth transmission gear 412, a thirteenth transmission gear 413, and a fourteenth transmission gear 414 that are sequentially rotatably arranged in the first housing 1. The first output gear 31 meshes with the eleventh transmission gear 411, the twelfth transmission gear 412 meshes with the eleventh transmission gear 411, the thirteenth transmission gear 413 meshes with the twelfth transmission gear 412, and the fourteenth transmission gear 414 meshes with the thirteenth transmission gear 413;

[0043] The first output gear 31 at the first end meshes with the eleventh transmission gear; the first input gear 21 at the first end meshes with the fourteenth transmission gear 414. The driving member at the first end drives the first output gear 31 to rotate, thereby driving the eleventh transmission gear 411, the twelfth transmission gear 412, the thirteenth transmission gear 413, and the fourteenth transmission gear 414 to rotate, and further driving the first input gear 21 to rotate, thereby driving the first output shaft 2 at the first end to rotate.

[0044] The fourth transmission assembly includes a forty-first transmission gear 421, a forty-second transmission gear 422, a forty-third transmission gear 423, and a forty-fourth transmission gear 424 that are sequentially rotatably arranged in the first housing 1. The first output gear 31 meshes with the forty-first transmission gear 421, the forty-second transmission gear 422 meshes with the forty-first transmission gear 421, the forty-third transmission gear 423 meshes with the forty-second transmission gear 422, and the forty-fourth transmission gear 424 meshes with the forty-third transmission gear 423;

[0045] The first output gear 31 at the second end meshes with the forty-first transmission gear; the first input gear 21 at the second end meshes with the forty-fourth transmission gear 424. The driving member at the second end drives the first output gear 31 to rotate, thereby driving the forty-first transmission gear 421, the forty-second transmission gear 422, the forty-third transmission gear 423, and the forty-fourth transmission gear 424 to rotate, and further driving the first input gear 21 to rotate, thereby driving the first output shaft 2 at the second end to rotate.

[0046] The sub - 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.

[0047] The second housing 5 is rotatably connected to the first housing 1. The first output shaft 2 is disposed through the second housing 5, and the first output shaft 2 is rotatably connected to the second housing 5.

[0048] The first output wheel 22 is arranged at one end of the first output shaft 2 away from the first housing 1. Specifically, the first output wheel 22 is the output wheel of the toy car.

[0049] A second output gear 23 is arranged on the first output shaft 2. The second transmission assembly includes a plurality of meshed second transmission gears 71. The second output gear 23 meshes with the adjacent second transmission gear 71. The second output shaft 6 is arranged at one end of the second housing 5 away from the first output shaft 2. A part of the second output shaft 6 is exposed outside the second housing 5. A second output wheel 62 is arranged on the second output shaft 6. A second input gear 61 is arranged on the second output shaft 6. The second input gear 61 meshes with the adjacent second transmission gear 71. Specifically, the second transmission assembly includes three second transmission gears arranged in sequence along the length direction of the second housing 5. The first output gear 31 and the second input gear 61 respectively mesh with the two second transmission gears 71 at both ends. 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.

[0050] Among them, 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 Mecanum wheels.

[0051] At this time, four output wheels are arranged on both sides of the toy car, that is, the toy car is an eight-wheel toy car.

[0052] Although the toy car in this embodiment is an eight-wheel toy car, this is not a limitation to the present utility model. On the premise of not deviating from the principle of the present utility model, in other embodiments, the toy car can specifically also be a six-wheel toy car. The second transmission assembly, the second output shaft, the second output gear of the first output shaft, and the output wheel on the second output shaft are not arranged on the first housing at one end of the toy car. Correspondingly, the first housing also becomes shorter. At this time, it is a six-wheel toy car. All of these do not deviate from the basic principle of the present utility model and will fall within the protection scope of the present utility model.

[0053] The gearbox further includes a third output gear 11 which is rotatably arranged on the first housing 1 and part of it is exposed outside the first housing 1. A third input gear 51 is arranged on the first housing 1 and meshes with the third output gear 11.

[0054] The second driving member 8 is in transmission connection with the third output gear 11 for driving the third output gear 11 to rotate, and then driving the first housing 1 to rotate. The rotation of the first housing 1 can make the whole toy car rise and fall, and can also cross obstacles, etc.

[0055] The child also includes a third transmission assembly, which is arranged in the first housing 1. The second driving member 8 and the first housing 1 are in transmission connection with the third output gear 11 through the third transmission assembly. A fourth output gear 81 is arranged on the second driving member 8. The third transmission assembly includes a thirty-first transmission gear 91, a thirty-second transmission gear 92, a thirty-third transmission gear 93, a thirty-fourth transmission gear 94 and a thirty-fifth transmission gear 95 arranged in sequence. The thirty-first transmission gear 91 meshes with the thirty-second transmission gear 92, the thirty-second transmission gear 92 meshes with the thirty-third transmission gear 93, the thirty-third transmission gear 93 meshes with the thirty-fourth transmission gear 94, the thirty-fourth transmission gear 94 meshes with the thirty-fifth transmission gear 95. The thirty-first transmission gear 91, the thirty-second transmission gear 92, the thirty-third transmission gear 93, the thirty-fourth transmission gear 94 and the thirty-fifth transmission gear 95 are arranged around the fourth output gear 81, and the fourth output gear 81 meshes with the thirty-fifth transmission gear 95;

[0056] A fourth input gear 111 is arranged on the third output gear 11, and the fourth input gear 111 meshes with the thirty-first transmission gear 91.

[0057] Specifically, the second driving member 8 is specifically a driving motor. The driving motor drives the fourth output gear 81 to rotate, and then the thirty-first transmission gear 91, the thirty-second transmission gear 92, the thirty-third transmission gear 93, the thirty-fourth transmission gear 94 and the thirty-fifth transmission gear 95 rotate, and then drives the third output gear 11 to rotate to drive the first housing 1 to rotate.

[0058] Third output gears 11 are arranged at both ends of the tooth box, and the second driving member 8 is only in transmission connection with the third output gear 11 at the first end.

[0059] The two tooth boxes are respectively a first tooth box and a second tooth box. The third output gear 11 at the first end of the first tooth box is connected to the third output gear 11 at the second end of the second tooth box 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 tooth box to rotate at the same time. Furthermore, the two first housings 1 at one end of the toy car can rotate, enabling the toy car to climb over obstacles.

[0060] So far, the technical solution of the present utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easily understood by those skilled in the art that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, 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 all fall within the protection scope of the present utility model.
