In an exemplary embodiment, the control assembly 8 is provided with a control chip 81. The control chip 81 mainly receives operation instructions through radio signals. It should be understood that, the control chip 81 may also receive operation instructions through bluetooth communication. In the present disclosure, the manner in which the control chip 81 receives operation instructions is not limited. The control chip 81 controls the steering assembly, the power assembly, and the driven assembly to complete corresponding actions according to the received operation instructions. It is noted that the driving wheel 5 is used as the front wheel of the toy car and is provided with a plurality of dents in the tire surface of the driving wheel 5 to increase the friction between the driving wheel 5 and the ground. The surface of the driven wheel device of the driven assembly is provided with less dents and is relatively smooth. Since the surface of the driving wheel 5 has multiple dents and the surface of the driven wheel device has fewer dents, the friction between the driving wheel 5 and the ground is greater, while the friction between the driven wheel device and the ground is smaller. The toy car of the present disclosure may realize more drifting actions by relying on the power assembly, the steering assembly, and the driven assembly. Specifically, when the toy car is driven by the power assembly, the steering assembly controls the driven wheel device of the driven assembly to turn a preset angle, which causes the driving wheel 5 and the driven wheel device to move in different directions, as a result, the toy car drifts. It should be noted that the drift direction of the toy car is mainly determined by the turn direction of the driven wheel device controlled by the steering assembly. The housing 1 is preferred made of plastic material. Of cause, the housing 1 may also be made of other materials. In the present disclosure, the material of the housing 1 is not specifically limited.
In the above embodiment, the power assembly, the steering assembly, the control assembly 8, the driving wheel 5, and the driven assembly are provided. The power assembly is connected to the driving wheel 5, and the driving wheel 5 is configured to provide power to the toy car. The steering device of the steering assembly is connected to the driven wheel device of the driven assembly, and cooperates with an elastic device of the steering assembly to make the driven assembly turn at a preset angle. The control assembly 8 is configured to receive control commands, and control the steering assembly to make the driven wheel device steer. During the toy car moving, when the movement direction between the driven wheel device and the drive wheel 5 offset, that is, the movement direction of the driven wheel device and the movement direction of the drive wheel 5 is different, the toy car drift. The toy car of the present disclosure may achieve more angles of drift benefit from a preset angle steering of the driven assembly cooperating with the steering of the driving wheel 5, thereby increasing the user's playing experience.
Optionally, the steering assembly includes a first steering device 2, a driving gear 23, a rotating gear 22, and a connecting rod. The driving gear 23 is mounted on the driving end of the first steering device 2, and is meshed with the rotating gear 22. The rotating gear 22 is mounted on the housing 1, the connecting rod is installed below the rotating gear 22 and fixed to a fixing cover on which the drive wheel 5 is mounted, and the fixing cover is movably mounted on the housing 1. The power assembly includes a drive motor 7, a first transmission gear 71, a second transmission gear 72, a third transmission gear 73, and a fourth transmission gear 74. The drive motor 7, the first transmission gear 71, the second transmission gear 72, the third transmission gear 73, and the fourth transmission gear 74 are all installed in the fixing cover. The driving end of the drive motor 7 is connected to the first transmission gear 71, the first transmission gear 71 is meshed with the second transmission gear 72, the second transmission gear 72 is meshed with the third transmission gear 73, the third transmission gear 73 is meshed with the fourth transmission gear 74, and the fourth transmission gear 74 is connected with the driving wheel 5.
In the embodiment of the present disclosure, the first steering device 2 may control and drive the driving wheel 5 to turn from 0° to 360° through the driving gear 23. Specifically, the driving gear 23 is meshed with the transmission gear, the transmission gear is movably installed inside the housing 1, the connecting rod is installed below the transmission gear and connected with the fixing cover, and the fixing cover is connected with the driving wheel 5. The driving motor 7 drives the driving wheel 5 to rotate, specifically, when the driving motor 7 starts to work, power is provided to drive the driving wheel 5 to rotate through the transmissions between gears. The size of each gear is different, and the output end of the driving motor 7 is connected to the first transmission gear 71 having the smallest size. It is more labor-saving and electricity-saving to drive a large gear through a small gear. When the first transmission gear 71 rotates, the second transmission gear 72 is driven to rotate. The second transmission gear 72 defines more gears on its outer surface, the third transmission gear 73 is meshed with the gears in the middle of the second transmission gear 72. The second transmission gear 72 drives the third transmission gear 73 to rotate. When the third transmission gear 73 rotates, the fourth transmission gear 74 will also rotate since the fourth transmission gear 74 is meshed with the third transmission gear 73. The fourth transmission gear 74 is connected with the driving wheel 5, so the driving wheel 5 will also rotate when the fourth transmission gear 74 rotates, so as to provide forward power for the toy car.
During the toy car moving forward, if a steering is required, the control chip 81 controls the first steering device 2 to turn based on a steering command received by the control chip 81. The turning of the first steering device 2 causes the driving gear 23 to rotate, the rotation of the driving gear 23 drives the transmission gear to rotate, and the transmission gear drives the connecting rod to turn, thereby enabling the driving wheel 5 to turn. In case the driving wheel 5 turns and the driven wheel device does not turn, the toy car steer; in case the driving wheel 5 does not turn and the driven wheel device turns, the toy car drifts; and in case the driving wheel 5 and the driven wheel device turns at the same time and at a same angle, the toy car slides.

In case the second steering device 3 starts to turn, the second steering device 3 drives the connecting sleeve 32 to turn, then the fixing rod 38 is driven to move in the notch of the connecting plate 33. When the fixing rod 38 contacts the inner edge of the notch, the connecting plate 33 is powered to drive the driven wheel to turn at a preset angle.
