Background technique

With the continuous expansion of market demand, the electric bicycle industry has also been developing rapidly, and there is a tendency to catch up with the popularity of bicycles. In order to distinguish themselves from competitors, various electric bicycle manufacturers have launched their own exclusive interface connection methods, which are not compatible with each other. At present, the existing electric bicycle chargers in the market are battery charging cables and charger circuits integrated. Soldering method. What's more, such as the situation that the interface is the same but the positive and negative polarities are reversed, there is a direct danger of damaging the battery, but the country's promotion and implementation of technical standards for the electric bicycle industry is relatively lagging behind.

At present, if a user needs to purchase a 48V charger in the market, he must find a charger that matches its interface and electrodes, and there are as many as 4 or 5 types of such interfaces, which has caused many problems for the majority of users and supporting service providers. inconvenient. To deal with this important problem that needs to be improved urgently, it is necessary to study and explore a universal electric bicycle charger that is compatible with various interface connection methods.

Utility model content

The utility model provides a universal charger for electric bicycles. The purpose of the utility model is to solve the problems that there are many interface connection modes in the existing electric bicycle industry, it is inconvenient to charge batteries of different electric bicycles, and there is no safety guarantee.

The electric bicycle universal charger of the utility model will be realized through the following technical solutions:

A universal charger for electric bicycles, which includes a charger circuit, a charger case, a 220V power cable and its plug, and a battery charging cable, wherein the battery charging cable has corresponding charging interfaces for different interface connection methods, and is characterized in that: The connection between the battery charging cable and the charger circuit described above is movable.

Further, the movable type means that the battery charging cable and the charger circuit realize the charging work by plugging and unplugging, and the battery charging cables corresponding to different interface connection modes can be freely replaced.

Furthermore, the charger circuit provides 48V DC voltage, and is suitable for 20AH and 12AH storage batteries.

Still further, the charger circuit has an overcharge protection module and a short circuit protection module.

The universal charger for electric bicycles of the utility model has the beneficial effects that it can well solve the problem that charger products are difficult to match with different charging interfaces of electric bicycles. Only one kind of charger is needed, coupled with cheap cables with different interfaces, the matching of charging interfaces can be realized flexibly, which has good economic and social benefits.

Detailed ways

The embodiments of the universal charger for electric bicycles of the present invention will be further described in a non-limiting manner in conjunction with the accompanying drawings, so as to deepen the understanding of the essence of the invention in a more intuitive manner.

A universal charger for electric bicycles comprises a charger circuit, a charger case, a 220V power supply cable and its plug, and a battery charging cable, wherein the battery charging cable is provided with corresponding charging interfaces for different interface connection modes. In particular, the connection of the battery charging cable to the charger circuit is movable.

As shown in FIG. 1 , it is a three-dimensional appearance view of an embodiment of the universal charger for electric bicycles of the present invention. It can be clearly seen from the figure that the electric bicycle universal charger of the utility model is mainly composed of a charger case 1, a 220V power supply cable 2 and a battery charging cable 3, wherein:

The charger box shell 1 is fixedly provided with a charger circuit 11, and one end of the charger circuit 11 is welded with a 220V power cable 2, which provides a 48V DC voltage, and is suitable for batteries of 20AH and 12AH. The other end is specially designed with a charging cable connection base 12 for plugging in the battery charging cables 3 that match different interface connection modes.

As shown in FIG. 2 , the independent appearance of the battery charging cable of the embodiment, wherein the two ends of the battery charging cable 3 are respectively provided with a charging cable connector 31 and a charging interface 32 . The charging cable connector 31 is corresponding to the charging cable connecting seat 12 on the charger circuit 11, and can realize the charging work through simple plugging and unplugging, and freely replace the battery charging cables 3 corresponding to different interface connection modes. It should be noted that the charging cable connectors 31 for different interface connection modes are completely consistent, while the charging interface 32 at the other end has different forms according to the different interface connection modes. That is to say, through this design scheme, the differentiation of the entire charger can be unified by a simple change of the very cheap battery charging cable 3 .

In addition, as shown in FIG. 3 , the independent appearance diagram of the charger circuit of the embodiment, in addition to the common voltage conversion unit of the general charger, the charger circuit 11 also adds an overcharge protection module 111 and a short circuit protection module. 112. These user-friendly designs can further prolong the service life of electric vehicle rechargeable batteries. In particular, it is different from the welding connection method of charging cables of general chargers. The universal charger of the present invention is specially designed with a charging cable connection seat 12 in the connection part of the charger circuit 11, which is convenient for the conversion of charging cables 3 with different charging interfaces 32. Plug and play.

To sum up, the utility model solves the problem that the charger product is difficult to match with different charging interfaces of electric bicycles. It only needs a charger with strong compatibility and is equipped with cheap cables with different interfaces, that is, The matching of the charging interface can be realized flexibly, and the utility model has good economic and social benefits, and its application prospect is very broad.
