Multifunctional lithium battery solar charger

Abstract

A multifunction lithium battery solar charger is used for charging the digital electronic products, which has a case with the shape of cuboid flat box having small volume, wherein the front is provided with a solar plate, and the back is provided with an alternating current active plug hinged with the case which can be pressed into the plug slot and is ejected when using; a lithium battery cover is also arranged on the back and the battery can be changed when opening the case cover; a joint, a switch, a charging state indicator light and an electric energy reverse indication are arranged on one side; an electronic circuit plate is arranged the case; a plurality of conversion adapters are provided. The production of the invention can be the standby after being full of electricity by the alternating current or the sun illumination. When in outgoing, only the charger is carried for the digital electronic product charging such as the mobile telephone and the digital camera. A plurality of conversion adapters are suitable for the electrical appliance with different interfaces. The invention can replace the chargers of all the 3.6 V DC production with small volume and convenient usage.

Description

technical field [0001] The invention relates to the technical field of a device for directly converting chemical energy into electrical energy, in particular to a device for charging and maintaining a secondary battery using solar energy. Background technique [0002] Mobile phones, digital cameras and other digital electronic products are equipped with chargers. When the power is insufficient, they need to be charged in time. Generally, the chargers are directly connected to the mains for power, but they cannot be connected to the mains under certain conditions. Use; In order to solve this problem, my country's utility model patent once disclosed a kind of "solar charger for mobile phone", patent No. 99202995.3, which is composed of two boards pivoted with one side of the pivot seat, and on the other The side is provided with buckles that can be buckled or separated from each other. The opposite inner side of each board is provided with a solar charging board, and a wire is c...

Problems solved by technology

[0002] Mobile phones, digital cameras and other digital electronic products are equipped with chargers. When the power is insufficient, they need to be charged in time. Generally, the chargers are directly connected to the mains for power, but they cannot be connected to the mains under certain conditions. Use; In order to solve this problem, my country's utility model patent once disclosed a kind of "solar charger for mobile phone", patent No. 99202995.3, which is composed of two boards pivoted with one side of the pivot seat, and on the other The side is provided with buckles that can be buckled or separated from each other. The opposite inner side of each board is provided with a solar charging board, and a wire is connected by an internal conversion circuit. The connector at the other end of the wire can be connected to the socket on the mobile phone. Plug and connect, and set up the cable management area; this solution only proposes the shape and connection of the charger, and the function is single, it cannot take power from the mains, and the user needs to bring an ordinary AC charger
