Embodiment Construction

[0019] The intelligent tracking electric vehicle of the present invention will be described in detail below in conjunction with examples and accompanying drawings.

[0020] Such as figure 1 As shown, the 220v AC power is connected to the DC stabilized power supply (2), and the 12v DC output is realized to the transmitter (3) after rectification and step-down. In the transmitter device, the AC voltage signal is converted into an AC voltage signal after high-frequency inversion, and loaded into the compensation The primary side of the loosely coupled transformer (tracking coil (4)) realizes resonant coupling with the receiving coil (5) loaded under the chassis of the electric vehicle, thereby supplying electric energy to the electric vehicle, and the electric vehicle can follow the track The coil drives automatically.

[0021] Such as figure 2 As shown, the 220v AC is stepped down by a transformer and sent to a rectifier bridge composed of 4 diodes, and then through the LM781...

Abstract

The invention relates to a design of an intelligent tracking electric toy car based on the non-contact power transmission technology, which comprises a direct-current stabilized-voltage power source (provided with a primary rectifying circuit), a transmitting device (comprising an intelligent tracking coil) and an electric toy car (carrying a receiving device and a secondary rectifying circuit). After the electric toy car is connected with a 220v general home lighting power source and provided with a wireless remote controller, the electric toy can run around the tracking coil with the diameter of 2m intelligently, and can run freely within the circumference in the diameter of 5m. The design of the intelligent tracking electric toy car based on the non-contact power transmission technology is light in structure and flexible in operation. The electric toy car can run continuously by means of non-contact power transmission without use of batteries, is suitable for the group of children to play widely and is energy-saving and environment-friendly.

Description

technical field [0001] "Wireless power transmission" is to use a special device to convert the electric energy of the power supply into energy that can be transmitted wirelessly, and then convert this energy back to electric energy at the receiving end, so as to reach the wireless power supply for electrical appliances. [0002] The invention belongs to the brand-new application field of the non-contact energy transmission technology, especially on the basis of intelligent tracking, it realizes the non-contact electric energy transmission to the electric vehicle, thereby eliminating the drawbacks of the previous toy electric vehicles needing to be powered by batteries. Simple, intelligent and flexible, realizing the technical concept of energy saving and environmental protection. Background technique [0003] Traditional toy electric vehicles require battery power, which can cause environmental pollution, difficulty in sustainable use, and poor contact caused by the aging of...
