In this embodiment, referring to fig. 1, the general mobile power supply has an approximately rectangular structure, and is internally formed by connecting 5 single batteries in parallel and series, and the rectangular structure of the general mobile power supply has a length of about 88-108 mm, a width of about 72-88 mm, and a height of about 19.8-24.2 mm. It should be noted that the size of the universal mobile power supply is not limited to this range, and the size thereof varies with the number and arrangement of the internal single cells, and the like, and can be used as an embodiment of the present invention. In the present embodiment, the battery pack is composed of a plurality of single cells 1 of a cylinder (see fig. 4), the cylinder includes one side surface and two circular bottom surfaces, the side surface of the cylinder is a cell wall 5, one bottom surface of the cylinder is a positive electrode end 7a of the single cell, the other bottom surface is a negative electrode end 7b of the single cell, and the positive electrode end 7a and the negative electrode end 7b are collectively referred to as an extreme 7. The two bottom surfaces of the single cell 1 each have a central axis 9, which central axis 9 corresponds to the central axis 9 of the cylinder (single cell). In this embodiment, the plurality of unit cells are drawn close to each other along the cell walls, the respective central axes are parallel to each other, the plurality of unit cells are arranged side by side and are assembled closely parallel to each other to form a single assembled battery structure approximating to a rectangular parallelepiped 11 (see fig. 5), and a plane defining the upper and lower faces of the rectangular parallelepiped 11, where the area formed by the cell walls is large, is a first wall face 11a, a plane defining the left and right faces of the rectangular parallelepiped, where the area formed by the cell walls is small, is a second wall face 11b, a plane defining the front and rear faces of the rectangular parallelepiped, where the extreme components of the cells are extreme faces 11c, and the area of the extreme faces 11c is smaller than that of the first wall face 11a.
In this embodiment, referring to fig. 1, the housing 300 is a flat, approximately rectangular housing, the interface 201 is disposed in the housing, the opening 301 is disposed on the housing smoothly, and there are no protruding hooking bosses on each surface, so as to ensure the holding comfort of the universal mobile power supply, and the appearance is similar to that of the mobile power supply. Specifically, the rectangular parallelepiped housing 300 has 6 housing surfaces, namely, a top surface, a bottom surface and four other side surfaces having the largest area, wherein the top surface and the bottom surface are a pair of flat surfaces parallel to each other, and are free of any stepped protrusions, one pair of opposite side surfaces is a flat curved surface, the other pair of opposite side surfaces is a flat surface, the top surface and the bottom surface support portions of the two first wall surfaces 11a of the battery, and the four side surfaces support portions of the second wall surface 11b and the extreme surface 11c of the battery.
Further, the circuit board is arranged on one side of one extreme surface 11c and is positioned between the battery pack and one side surface of the shell corresponding to the extreme surface 11c, and the plane of the circuit board is orthogonal to the central axis 9 of the single battery. It is easily conceivable that the circuit board may also be arranged on one side of one second wall surface 11b, between the battery pack and one side surface of the housing corresponding to this second wall surface 11b, the plane of the circuit board being parallel to the central axis 9 of the single cell. The side surface area of the shell is smaller than the top surface/bottom surface, the volume of the shell is smaller than that when the circuit board is arranged on the top surface/bottom surface, the appearance of the shell is lengthened and thinned, and therefore the whole volume of the universal mobile power supply is more compact and smaller. It is easy to understand by those skilled in the art that the single battery is not limited to a cylindrical single battery, and other single batteries with other shapes such as cuboid, flat, etc. capable of realizing energy storage can be arranged and combined into a battery pack similar to cuboid according to a certain method, and in this case, the shape of the shell is still cuboid suitable for the battery pack, two surfaces with the largest area of the cuboid shell are a top surface and a bottom surface, and other surfaces are side surfaces, and accordingly, the circuit board is arranged between the battery pack and one side surface, which is all the embodiments of the invention.
It is to be understood by those skilled in the art that the shape of the rectangular parallelepiped of the housing is not limited to a standard rectangular parallelepiped defined mathematically, and may be a rectangular parallelepiped having smooth curved sides as in the first embodiment, and any rectangular parallelepiped having an overall shape of substantially a rectangular parallelepiped and having no irregular portion such as a protruding step on the housing may be used as the embodiment of the present invention. It should be noted that, in the prior art, the top surface of the battery pack is not a plane, but is a high-step top surface with a protrusion due to the discharging interface of the tool, which does not fall into the protection scope of the present invention. The battery pack includes a holder 3 for fixedly supporting a plurality of single cells in an approximately rectangular integrated structure. In this embodiment, the support is a split support, including a first support 3a and a second support 3b, see fig. 3, where the first support and the second support are respectively fixed on the upper and lower extreme surfaces 11c of the battery pack, so as to fix the single battery. It will be appreciated by those skilled in the art that the bracket may be an integral bracket, not separable, and that the securing of the individual batteries may be accomplished as well.
A flaky insulating plate 13 is arranged between the battery pack and the circuit board to prevent the circuit board from conducting electricity near the positive and negative electrode plates of the single battery. It should be noted that the insulating plate may not be provided when the circuit board and the pole piece of the battery are far enough away from the pole piece of the battery to not affect the circuit board.
Referring to fig. 7, in the present embodiment, the interface 201 of the universal mobile power supply includes 3 independent interface units, namely, the charging interface unit 15, the first discharging interface unit 17 and the second discharging interface unit 19, which are disposed on the circuit board 300. The charging interface unit 15 can be connected with a charger, the charger is connected with a wall power socket, and when the electric quantity of the universal mobile power supply is insufficient and needs to be charged, the universal mobile power supply is charged through the charging interface; the first discharging interface unit 17 is connected with an external portable electronic device to supply power to the external portable electronic device, a corresponding interface unit is arranged outside the portable electronic device, an energy storage unit and a working circuit are arranged inside the portable electronic device, the energy storage unit supplies power to the working circuit, when the portable electronic device is connected with the universal mobile power supply, the universal mobile power supply can charge the energy storage unit inside the portable electronic device, and when the portable electronic device is not provided with the energy storage unit or a user selects not to charge the energy storage unit, the universal mobile power supply can directly supply power to the working circuit; the second discharging interface unit 19 can output the electric energy required by the electric tool to supply power to the electric tool.
In this embodiment, the charging interface is a USB interface, and the charger is a charger capable of charging the portable electronic device, for example, a USB charging stand capable of charging a mobile phone produced by a manufacturer for a mobile phone, a digital camera, and the like.
In the present invention, the second discharging interface unit 19 of the universal mobile power supply cannot be directly connected to the interface unit on the electric tool to supply electric power thereto, and needs to pass through an adapter. The second discharging interface unit 19 has a mechanical structure of a first configuration, and an interface capable of directly coupling an external power source outputting electric power with an interface unit on the electric tool has a mechanical structure of a second configuration, the first configuration being different from the second configuration, so that the universal mobile power source 400 cannot be directly connected with any electric tool 35.
Further, in this embodiment, the top surface and the bottom surface of the housing define a space, that is, a space region (not shown) is formed between two parallel planes of the top surface and the bottom surface, and the second discharge interface unit 19 is located in the space region, so that there is no discharge interface structure protruding outwards on the top surface and the bottom surface of the housing, and the top surface and the bottom surface also have no uneven protruding portion of the shell surface caused by the discharge interface structure, thereby further ensuring smoothness and flatness of the overall shape of the universal mobile power supply.

Furthermore, the general mobile power supply internally comprises a control module, and when the general mobile power supply charges or supplies power for the portable electronic equipment, abnormal states such as over-temperature, over-charge, over-discharge, over-current and the like occur, so that the charging or discharging process of the general mobile power supply can be controlled. It should be noted that the battery voltage of the general mobile power supply and the output voltage of the second discharging interface are not limited to 20V, the voltage varies with the design requirement, and the corresponding internal voltage boosting circuit and voltage dropping circuit also vary, which can be used as the embodiments of the present invention and are within the protection scope of the present invention.
