In a further improvement, the plug outlet 7 is a DC series socket.

In a further improvement, the DC series socket is a 7.4V aircraft carrier plug outlet.

The utility model has the advantages that:

the utility model can meet the power supply requirements of LED photography lamps, cameras, single-lens reflex and alternative mobile power supplies, and can also meet the charging requirements of NP-F series batteries; meanwhile, the NP-F series battery box adopts the design of a plurality of quarter nuts on the design, so that the use range and the use flexibility are greatly improved, the problem of industrial pain is solved, and the use cost of the externally-hung NP-F series battery is reduced for users.

Description of the drawings:

FIG. 1 is a schematic view of a battery pack;

fig. 2 is a circuit configuration diagram of the present invention;

FIG. 3 is a circuit diagram of a charging circuit;

fig. 4 is a circuit diagram of the step-down circuit.

The specific implementation mode is as follows:

a battery case for charging NP-F series batteries as shown in fig. 1, comprising a battery case body 1, an upper quarter nut 2 fixed to the upper part of the battery case body 1, and a lower quarter nut 3 fixed to the lower part; the battery box body 1 is provided with a charging input interface 4, the charging input interface 4 is electrically connected with an NP-F series battery 6 in the battery box body 1 through a charging circuit 5, the NP-F series battery 6 is electrically connected with a plug output port 7 and a voltage reduction circuit 8, and the voltage reduction circuit 8 is electrically connected with a USB output port.

Input interface 4 charges is Type _ C terminal, mini android terminal or iphone terminal.

Input interface 4 charges is Type _ C terminal. Type _ C terminal is 5V Type _ C terminal.

The plug outlet 7 is a DC series outlet. The DC series socket is a 7.4V aircraft carrier plug outlet.

The circuit framework adopts a framework mode that 5V is input through Type _ C, the battery is charged through a charging circuit, a voltage reduction circuit outputs 5V through a USB, and a DC series socket outputs 7.4V. The structure adopts a framework mode of upper and lower double quarter nuts. The circuit has the advantages of simple and reliable structure, wide applicability, low use cost of users and the like.

Fig. 1 is a system block diagram of a specific embodiment of the circuit of the present invention. Type _ C is the input terminal of battery case, can also be mini android terminal and iphone terminal except with Type _ C terminal. The charging circuit is the core part of the battery charging function of the system, and can automatically identify the output current of the charging head or the charging treasure so as to adjust the proper charging current for the NP-F series battery. The NP-F series battery only provides one bayonet corresponding to the NP-F series battery in the system. The buck circuit and USB output are another core part of the system, whose function is to buck the NP-F series battery to 5V for output via the USB terminal for use by other suitable devices. The output of the DC series socket is 7.4V, mainly for supplying power to single-lens reflex and video cameras and other devices requiring 7.4V, and the conventional DC series socket is, for example: DC044, DC005, etc., but some special DC series outlets are of course possible.

Figure 2 is a specific embodiment of the structural frame of the utility model. The upper quarter nut and the lower quarter nut are respectively arranged at the upper part and the lower part of the drawing, and the quarter nuts at the right lower part are used for fixing the battery box on the bracket; the quarter nut right above is used for fixing other electric equipment (such as pocket lamps, mobile phones and other suitable electric equipment), and the design of the whole battery box brings great convenience and flexibility to users.

The whole system integrates charging and discharging, can reduce the use cost for users (a special full electric appliance and a switching battery box are needed to be matched for a common plug-in NP-F series battery), and can also adapt to a wide use range (for example, the system can replace the functions of a traditional large-capacity charger and can also supply power for a single lens reflex and a camera). Meanwhile, the use flexibility of the product is improved (the design of upper and lower double quarter nuts is adopted).

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
