Abstract

The invention discloses a wireless charging device for an electric bicycle. The device comprises an electric bicycle and a charging pile for wirelessly charging the electric bicycle; the electric bicycle comprises a wireless charging receiver, a controller, a rechargeable battery and a power drive; the charging pile comprises a wireless charging transmitter and a control box; the wireless charging receiver is of a tubular structure and is arranged on a grip of the electric bicycle, the wireless charging transmitter is of a cylindrical structure, and the wireless charging transmitter and the wireless charging receiver are used in a matched mode; the control box is connected with the wireless charging transmitter and is used for supplying power to the wireless charging transmitter and controlling the wireless charging transmitter; the wireless charging receiver is electrically connected with the rechargeable battery and is used for generating induced electromotive force according to the electromagnetic waves emitted by the wireless charging emitter to supply power to the rechargeable battery; and the controller controls the rechargeable battery to supply power to the power drive and controls the power drive to work. The invention achieves the effects of reducing the cost, improving the usability of wireless charging of the electric bicycle and improving the charging reliability.

Description

technical field [0001] Embodiments of the present invention relate to electric bicycle technology, and in particular to a wireless charging device for electric bicycles. Background technique [0002] As a kind of efficient, easy to use, and cheap public transport, electric bicycle is more and more popular. At the same time, electric bicycles have low environmental pollution and can better solve the problem of fossil energy shortages, so they are a very important link in the low-carbon economy. At present, most electric vehicles use wired charging, and the charging adapter is bulky and inconvenient to carry. The installation of wired public electric bicycle charging piles requires high environmental requirements and poor versatility. At the same time, frequent plugging and unplugging of power cables is not safe, and it is easy to cause equipment aging and wear. Destroying the waterproofness of the electrical parts of the vehicle, and the charging equipment that transmits ele...
