[0030] The present utility model will be described in detail below with reference to the accompanying drawings.

[0031] As Figures 1 - 3 shown, a portable power supply device includes an installation housing 1, an energy storage group 3 is arranged in the installation housing 1, the energy storage group 3 includes two battery cell groups connected in series or in parallel with each other, and the battery cell group includes a plurality of batteries 35;

[0032] The installation housing 1 includes a housing 11 processed and formed from a plastic material and a cover body 12 installed at the opening of the housing 1, a circuit board 13 is installed on the cover body 12, and the circuit board 13 is connected to the battery cell group; a power supply socket 2 is installed on the circuit board 13; an installation groove 14 is recessed and formed in the cover body 12, and an installation structure for installing the power supply socket 2 is formed in the installation groove 14.

[0033] Multiple battery cell groups can provide more energy storage for the power supply device. By adopting a dual - path nominal voltage, the nominal voltage after two battery cell groups are connected in series is twice the voltage of the original single - battery cell group; or the capacity of the power supply device after two battery cell groups are connected in parallel is twice the capacity of the original single - battery cell group, and the discharge current is further increased, thereby improving the discharge efficiency. It can be output in a low - temperature environment to charge electrical equipment; in addition, by positioning and installing the power supply socket 2 through the installation groove 14, the output stability during charging can be improved, making it more stable when used outdoors.

[0034] In one embodiment, the nominal voltage of a single battery cell group in this solution is 14.4V. After being connected in series, the nominal voltage of the battery 35 can reach 28.8V. The capacity of a single - path battery cell group is: 6Ah, and after being connected in parallel, it can reach 12Ah. The maximum discharge current can reach 10A, the working environmental temperature can reach a low temperature of - 40°C, the discharge efficiency exceeds 80%, and it can be charged in an environment with a low temperature of - 20°C.

[0035] Specifically, the power supply socket 2 includes a socket body 21 and a guide sleeve 22 coaxially formed around the socket body 21. A plurality of conductive contacts 23 are installed on the outer end face of the socket body 21. When an external electrical device is inserted into the socket body 21, the stability during connection can be improved through the guide sleeve 22, preventing the interface from moving radially and maintaining electrical connection with the conductive contacts 23.

[0036] Preferably, a plurality of guide strips 24 for anti-fool connection are axially formed on the outer ring wall of the socket body 21. When the interface is connected to the power supply socket 2, the guide strips 24 can ensure that the interface does not rotate during insertion, ensuring linear axial movement to connect and contact the conductive contacts 23, and further improving the connection stability.

[0037] Preferably, the guide sleeve 22 is provided with a connecting sleeve 25. The installation structure includes a mounting seat 15 formed in the mounting groove 14.

After the connecting sleeve 25 of the guide sleeve 22 is coaxially aligned with the connecting hole 16 of the mounting seat 15, the connecting screw 26 can be inserted into the locking nut 17, enabling the power supply socket 2 to be installed on the mounting seat 15 in the mounting groove 14.

[0039] Specifically, the battery cell group is divided into a first battery cell group 31 and a second battery cell group 32. The first battery cell group 31 includes two first insulating plates 33 for installing batteries 35. The batteries 35 of the first battery cell group 31 are installed between the two first insulating plates 33. The multiple batteries 35 are positioned and installed through the first insulating plates 33 to ensure stable storage of electrical energy. Similarly, the second battery cell group 32 includes two second insulating plates 34. The batteries 35 of the second battery cell group 32 are installed between the two second insulating plates 34. The multiple batteries 35 are positioned and installed through the second insulating plates 34 to ensure stable storage of electrical energy. The first insulating plates 33 and the second insulating plates 34 can prevent a short-circuit phenomenon from occurring between the first battery cell group 31 and the second battery cell group 32.

[0040] Among them, the second battery cell group 32 further includes a side insulating plate 36. The side insulating plate 36 is connected to one of the first insulating plates 33 of the first battery cell group 31. The first battery cell group 31 and the second battery cell group 32 are arranged vertically, the first insulating plate 33 and the second insulating plate 34 are arranged vertically, and a conductive connecting piece 37 is installed on one of the first insulating plates 33 of the first battery cell group 31. The other end of the conductive connecting piece 37 is connected to the second insulating plate 34. When the first battery cell group 31 and the second battery cell group 32 are connected in series, the conductive connecting piece 37 is used to achieve electrical connection.

[0041] Preferably, the conductive connecting piece 37 is an L-shaped conductive sheet. The L-shaped conductive sheet can be adapted according to the arrangement of the first battery cell group 31 and the second battery cell group 32, improving the overall connection stability and power supply stability.

[0042] In one embodiment, when the first battery cell group 31 and the second battery cell group 32 are connected in parallel, a positive electrode conductive sheet is installed at the positive electrode ends of the first battery cell group 31 and the second battery cell group 32, and a negative electrode conductive sheet is installed at the negative electrode ends of the first battery cell group 31 and the second battery cell group 32. The positive electrode conductive sheet and the negative electrode conductive sheet are used to achieve parallel connection.

[0043] In summary, it can be seen that the present utility model has the above-mentioned excellent characteristics, enabling it to enhance the efficiency that has never been achieved in the prior art during use and having practicality, thus becoming a product with extremely high practical value.

[0044] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
