System for power management and preventing unexpected acceleration of remote-controlled toy car

Abstract

The system for power management and preventing unexpected acceleration contains a microcontroller unit, a tact switch, an electronic regulation device for preventing unexpected acceleration, a voltage detection switch, one or more light emitting diodes, resistors, capacitors, transistors, and an inductor. After a battery is installed on the remote-controlled toy car, the battery's electricity will flow through the electronic regulation device and the voltage detection switch. On the other hand, the microcontroller unit receives signals from a detection and reception circuit and controls the throttle through a servo motor. As such, the battery power and the received signals are monitored to prevent the remote-controlled toy car from unexpected acceleration.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention generally relates to remote-controlled toy cars, and especially relates to a system for remote-controlled toy cars for efficient power management and for the prevention of unexpected acceleration.DESCRIPTION OF THE PRIOR ART[0002]Remote-controlled toy cars are popular among both adults and children. By a remote control console, the toy car is instructed to accelerate and turn at the player's will. Conventionally, inside the toy car, there is a detection and reception circuit for detecting and receiving instruction signals issued from the remote control console so that the toy car can perform acceleration, braking, turning, or backing up accordingly.[0003]Preferably, when not playing, the remote-controlled toy car is turned off to save the power of its battery. However, if the player forgets to switch off the power, the battery would soon be consumed. On the other hand, the remote-controlled toy car may has its throttle set ...

AI Technical Summary

Benefits of technology

[0005]Therefore, a main purpose of the present invention is to provide a system that will automatically make the remote-controlled toy car to enter a power saving mode when it is inoperative for a period of time, or when a low battery voltage is detected and an alarm is issued for a period of time.

[0006]Another purpose of the prevent invention is to provide a system to prevent the remote-controlled toy car's unexpected acceleration so that it is much safer to play.

[0008]The electronic regulation device contains inductors, a variable-frequency regulation circuit, and a regulation integrated circuit, for effective voltage stabilizing effect.

Problems solved by technology

However, if the player forgets to switch off the power, the battery would soon be consumed.

On the other hand, the remote-controlled toy car may has its throttle set in its last state and, when the battery is replaced and the power is turned on, a large instantaneous current could cause unexpected acceleration of the remote-controlled toy car.

This unexpected acceleration not only may cause damage to the remote-controlled toy car, but also may hurt the player or bystanders.
