Description

Technical Field

[0001] The utility model relates to the field of children's toy cars, in particular to a novel toy car driving structure and a toy car adopting the structure. Background Art

[0002] Existing toy car drive structures all use a central shaft to drive the wheels to achieve travel. However, this drive method is relatively complex, requiring a multi-stage transmission and connecting a drive gear to the central shaft drive gear for propulsion. When applied to a toy motorcycle, the central shaft drive method requires a central shaft, a central shaft drive gear mounted on the central shaft, and a power drive gear connected to the central shaft drive gear. This placement issue results in a wider toy motorcycle, which in turn increases its size. Furthermore, the central shaft drive method is relatively traditional and reduces playability. Utility Model Content

[0003] The purpose of this utility model is to address the deficiencies of the existing technology and provide a new toy car drive structure and a toy car using the structure, so as to solve the problems that the existing toy cars use the traditional central axis drive method, have a complex structure, and have low playability.

[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is:

[0005] A new toy car drive structure includes a power device, a power output gear set connected to the power device, and a drive gear set connected to the power output gear set. One end of the drive gear set is connected to the power output gear set, and the other end is connected to the toy car wheel. A gear ring is provided on one side of the toy car wheel, and the gear ring is connected to the power output gear set. The power output gear set drives the gear ring to rotate, thereby driving the toy car wheel to rotate.

[0006] The power device is an inertia drive device or a motor drive device.

[0007] The power output gear set includes a first power output gear and a second power output gear, wherein the first power output gear is connected to the output end of the power device, and the second power output gear is connected to the first power output gear and the driving gear set.

[0008] The driving gear set includes a first driving gear connected to the second power output gear, and a second driving gear connected to the wheel of the toy car, and the first driving gear and the second driving gear are connected through a rotating shaft.

[0009] A hub fixedly connected to the toy car frame is provided in the middle of the wheel of the toy car, and a tire movably connected to the hub is sleeved on the hub.

[0010] The gear ring is arranged on one side of the tire and corresponds to the driving gear.

[0011] A toy car includes a motorcycle-type toy car body, the motorcycle-type toy car body includes a toy car frame, front wheels and rear wheels respectively arranged at the front and rear ends of the toy car frame, and a driving structure arranged in the toy car frame, which adopts the novel toy car driving structure.

[0012] The beneficial effects of the present invention are as follows: the drive structure of the toy car of the present invention replaces the traditional method of using a central shaft to drive the rotation of the entire wheel, including the hub, with a tire mounted on the outer surface of a fixed hub. A gear ring is provided on one side of the tire to cooperate with the drive device, thereby driving the tire to rotate. This structure has fewer components, which can reduce the width of the motorcycle. At the same time, it does not require a cumbersome support structure around the inner circumference of the hub, which can significantly reduce the weight of the toy car. In addition, the drive structure of the present invention is more novel than the traditional drive method, is more playable, and is more attractive to children. BRIEF DESCRIPTION OF THE DRAWINGS
