Description

Technical Field

[0001] The invention relates to the field of toys, in particular to a remote control toy car. Background Art

[0002] With the improvement of living standards, remote control toy cars have become popular in ordinary families. Since the users of remote control toy cars are children, the flexibility of operation and novel functions of remote control toy cars are more popular among children. At present, general remote control cars have the functions of moving forward, moving backward, turning left and turning right. In order to realize the above functions, two gear boxes are generally set. The front gear box can realize the steering function, and the rear gear box is the forward and backward functions. The gear box includes upper and lower covers of the gear box, a transmission gear wheel, and a drive motor. After the remote control car is powered on, the remote control sends a command, and the remote control car receives it and decodes and sends a signal to the drive motor to work. The defects of the above-mentioned traditional remote control car are: because there are only two gear boxes, the function is single, the turning angle is large, the turning diameter of the 1:14 car model is about 2.5 meters, the factory site requirements are high, and the car needs to be played in a very spacious environment. In addition, since the existing toy car only uses rear-wheel drive when moving forward and backward, the playable terrain of the toy car is limited, especially the degree of climbing of the toy car will be greatly limited, which reduces the game experience of the player.

[0003] In order to improve the gaming experience, a solution is provided in the prior art, in which the four wheels of a remote-controlled toy car are set to rotate independently of each other, so that when turning, the two front wheels and the two rear wheels rotate in different directions respectively, so that the toy car can turn at a smaller angle. However, this structure is relatively complicated, and it is also necessary to control the two front wheels and the two rear wheels to rotate synchronously in order to make the toy car turn more smoothly. This solution will significantly increase the cost of the toy car. Summary of the invention

[0004] The purpose of the present invention is to solve the above-mentioned technical problems and provide a remote-controlled toy car. The present application is to provide a remote-controlled toy car structure with four-wheel drive and front and rear wheels that can turn in the same or different directions, thereby improving the terrain adaptability of the toy car and enriching the gameplay of the toy car.
