Description

A USB charging device for electric vehicles

technical field

The utility model relates to a USB charging device for an electric vehicle and relates to a charging device, in particular to a USB charging device suitable for an electric vehicle or an electric bicycle.

Background technique

Electric vehicles are the means of transportation commonly used by the majority of residents and migrant workers. The main function of electric vehicles is short-distance transportation, convenient and fast means of transportation. People have higher and higher requirements for the use of electric vehicles. Some require electric vehicles to have a long battery life and a long cruising range; some require a beautiful, generous, and dazzling appearance;

Now people have generally used digital products, such as mobile phones, ipads, digital cameras and other digital products, but often the digital products run out of power during use, thereby affecting study and work. At present, there are electric vehicles with charging devices on the market, but because they need to share electricity with the battery, the riding mileage is affected.

Utility model content

The purpose of this utility model is to provide a USB charging device for electric vehicles, which is equipped with a solar charger and installed on the faucet of an ordinary electric vehicle (or in the lower box of the seat cushion, or inside the trunk). When the mobile phone or other digital equipment is out of power, it can be charged through the data cable, which is convenient and fast to solve the urgent need.

The utility model is realized by taking the following technical solutions:

A kind of USB charging device for electric vehicle comprises device body, is provided with solar electric panel and USB socket on the main body; connected to the rechargeable battery, the rechargeable battery is connected to the charging conversion device through a wire, the charging conversion device is connected to the USB socket line, and the charging conversion device is connected to the electric vehicle battery through a wire; the charging conversion device converts the voltage of the electric vehicle battery It is the charging voltage of the digital product, and the charging voltage is provided to the digital product to be charged.

There is a selection switch between the charger conversion device and the battery of the electric vehicle and the rechargeable battery. When the selection switch is turned to the battery of the electric vehicle, the electricity of the battery of the electric vehicle is used; panels to generate electricity.

There is at least one USB socket.

The USB charging device for electric vehicles of the utility model has reasonable design, simple structure, convenient operation and low cost, which avoids the annoyance of people who especially choose electric vehicles and cannot work and study when digital products are powered off. The energy of electric vehicle batteries is organically combined, and users can freely choose what power source to use to charge digital products.
