Electric toy car powered by rail-type wireless power supply system

Abstract

The invention discloses an electric toy car powered by a rail-type wireless power supply system. The electric toy car powered by the rail-type wireless power supply system comprises a transmitter and a receiver which have the same self-resonance frequency, an electric toy car rail is arranged above the area in which a transmitting coil of the transmitter is located, the receiver and a commutating and voltage-stabilizing module are mounted on a chassis of the electric toy car, a receiver is connected to an input end of the commutating and voltage-stabilizing module, and an output end of the commutating and voltage-stabilizing module is connected to an electric motor of the electric toy car. A power source supplies power to the transmitter, the operation of the receiver and the operation of the transmitter are of resonant coupling under the resonant frequency, and energy which is received by the receiver is converted into a voltage-stabilized direct current through the commutating and voltage-stabilizing module and is supplied to the electric motor. The toy car moves on the rail, and the speed of the electric toy car can be adjusted through changes of the power and frequency. By means of the rail-type wireless power supply system, the electric toy car gets rid of the constraint of batteries, the size of the motor is reduced, the weight of a car body is reduced, the conversion efficiency of electric energy is high, pollution to the environment caused by the usage of the storage batteries is reduced, and a good effect in energy conservation and environment protection is achieved.

Description

technical field [0001] The invention relates to the field of wireless energy transmission, in particular to an electric toy car powered by a rail-type wireless power supply system. Background technique [0002] Electric toy cars and four-wheel drive vehicles are one of the common toys that children love. At present, these products on the market are powered by batteries. This method of replacing batteries has the following disadvantages: First, frequent battery replacements cause battery resources waste and environmental pollution; second, due to the weight of the battery itself, the motor on the toy car must increase the driving power when designing, which requires the use of a larger motor, and the manufacturing cost of the motor also rises accordingly. The speed itself will be limited to a certain extent. [0003] With the continuous development of wireless power transmission technology, there have been many breakthroughs in product applications, such as mobile phones and...
