Battery cover

Abstract

The invention dicloses a battery cover, which is arranged on a radio frequency emitter, and is charged in a noncontact inductive way. The battery cover comprises a cover body covering a battery jar of an electric product, a terminal group electrically connected with a charge battery and arranged towards the battery jar on the cover body, a power generation unit in a nontouch way arranged in the cover body. The nontouch power generation unit can induce radio-frequency signal of the radio frequency emitter so as to produce power and charge the charge battery through the terminal group. When an electric product adopts the battery cover disclosed by the invention, the change battery does not need be assembled or disassembled frequently; the electric product adopting the battery cover disclosed by the invention supplements power in a wireless inductive way; the problem that collecting wires is not easy is eliminated; consumers can supplement power to an electric product purchased in marketin a wireless inductive way simply by putting the battery cover disclosed by the invention on the electric product, and reequipping the electric product is not required.

Description

technical field

[0001] The invention relates to a device for charging rechargeable batteries of electric appliances. Background technique

[0002] Many items and tools often need to use batteries to supply the power needed for their operation, such as game controllers, remote controls, mobile phones, multimedia players, wireless mice, flashlights, PDAs, digital cameras and other electrical products, and The use of batteries and the recycling of waste batteries often cause a considerable degree of environmental protection problems. In recent years, reusable rechargeable batteries have gradually been used by people. In addition to reducing the number of waste batteries, it can also reduce consumer purchases. The cost of new batteries.

[0003] Generally speaking, when the rechargeable battery is exhausted, the rechargeable battery can be charged by an external power source, so that the electrical energy is converted into chemical energy and stored (the rechargeable battery wi...
