Description

Mini remote control toy car

TECHNICAL FIELD The present invention relates to a toy car, and in particular, to a miniature remote control toy car that can remotely control the lights and sounds of the toy car. Background technique

With the rapid development of technology and economy, and the continuous improvement of people's living standards, remote-controlled toy cars have become one of children's favorite toys. In order to enhance the reality of remote-control toy cars, at present, some remote-control toy cars are provided with headlights and sound generating devices. Chinese Patent Application No. 88211987. 7 discloses a "dual-channel remote-control toy car capable of emitting sound and light". As shown in FIG. 1 and FIG. 2, a flash device is provided on a toy car, and a sound emitting device is provided at an appropriate position on the vehicle body. The flash device is composed of a cam 3 and a group of contact pieces 4. The cam 3 is connected to the driving wheel shaft 6. The synchronous rotation with the shaft, the contact piece 4 is installed on one side of the gearbox 5, and is arranged at right angles to the cam 3. When the convex part of the cam rotates to the position of the contact piece, the convex part pushes the contact piece to connect the two contact pieces to achieve the purpose of turning on the vehicle light. When the convex part of the cam turns over the contact piece, the contact piece The elastic force of the contact returns to its original state, and the light switch is turned off, so that the lights are turned on and off. The sound generating device is composed of the integrated circuit 1 and the horn 2. After the power of the integrated circuit 1 is turned on, the sound can be output continuously through the horn 2 so that the toy car can achieve the purpose of sound. The shortcoming of the remote control toy car is that its flashing device and sound generating device are both set on the toy car. When the toy car is driving, the flashing device is driven by the cam to push the contact piece and the elastic force of the contact piece itself. The flickering light can not be controlled remotely. In addition, after the power of the integrated circuit in the sound device is turned on, the speaker will emit sound continuously, so it cannot control the sound randomly, so it is very easy to use. It is inconvenient and therefore reduces the fun of the remote control toy car.
