[0031] as follows:

[0032] Please see attached Figure 1-8 ,

[0033] The main structure includes a middle frame component 2 arranged between the two shells 1, and an internal component 3 is arranged in the middle frame component 2. The internal component 3 includes a control area 31 and a component area 32 with various components. The control area 31 and the component area 32 are arranged vertically in an "L" shape and connected. The control area 31 is composed of a PCB 310 and a contact 311 arranged on one side of the PCB 310. The middle frame component 2 includes a frame body 20, and a card slot 21 arranged on one side of the frame body 20 for connecting to an external interface 24. The other side of the card slot 21 is in close contact with the PCB 310. The other side of the frame body 20 is provided with a connection seat 25 for plugging and connecting plug bodies 4 of various specifications. The battery pack 3 of the internal component 3 0 is located in the enclosed area in the middle of the frame body 20, one side of the battery pack 30 is connected to the contact 311, and large areas on both sides of the battery pack 30 are in contact with the inner surfaces of the two shells 1, wherein the connecting seat 25 includes two parallel plug-ins 250 fixed to one side of the frame body 20, a guide column 252 is provided between the two plug-ins 250, and an adapter seat body 40 is provided on one side of the plug body 4 by three-side enclosure, and slots 42 for sleeved on the plug-ins 250 are provided on both sides of the adapter seat body 40, and a guide groove 43 for plugging and fixing with the guide column 252 is provided between the two slots 42, and the top of the two slots 42 is limited by a limiting member 41 to limit the top of the plug-in 250.

[0034] Here’s how it works:

[0035] The current national standard socket has a bendable structure with a plug 250, but if it is to be connected to an international standard plug, multiple conversion sockets (heads) are required. Due to the bendable nature, it is easy to shake, and the conductive sheet is exposed, and the safety does not meet international standards. This solution uses a fixed connection seat 25, and through the provided plug 250 and guide column 252, it can be conveniently and installably connected with the adapter seat 40 on the plug body 4. The slot 42 is sleeved on the plug 250, the guide groove 43 in the middle inserts and fixes the guide column 252, and the top limiter 41 closes the top of the plug 250 to prevent it from falling out, and then the fixing member 44 can be used to fix the positioning hole 251, that is, the installation of the plug body 4 and the connection seat 25 is completed.

[0036] When assembling the power source body, first separately place the control area 31 and the component area 32 vertically connected to one end of the control area 31 (the component area 32 can be fixed by the bottom plate, or fixed by the partition 22, or directly fixed to the shell 1 on one side), ensure that the contact 311 is reserved on the inside of the PCB 310, and then place the battery pack 30 (the battery pack 30 can be single-layer or multi-layer) in the middle space, connect one end of the battery pack 30 to the contact 311, and finally clamp the two sides of the shell 1 to the two sides of the frame body 20 (or fix it by screws) to complete the packaging. Since there is basically no wire inside, there is no need to open solder joints, connection points, etc. The large areas on both sides of the battery pack 30 are fitted with the shell 1 to dissipate the working heat as much as possible. The overall structure is easy to assemble, disassemble and maintain. The shell 1 includes a front shell 10 and a back shell 11 that are clamped on both sides of the frame body 20 respectively. The integrated frame body 20 is not easy to deform, and the shell 1 on both sides has anti-fall and shock absorption properties.

[0037] A preferred embodiment of the present invention: the front shell 10 and the back shell 11 are both aluminum shell structures, and a phase change heat conductive structure is filled between the aluminum shell structure and the battery pack 30.

[0038] A phase-change heat-conducting structure is used for filling to ensure that the surface of the battery pack 30 is in full contact with the inner surface of the shell 1 .

[0039] In a preferred embodiment of the present invention, each component in the component area 32 is fixed by a partition plate 22 disposed in the frame body 20 .

[0040] The partition 22 can be used to fix the components in the component area 32 and isolate the components from direct contact with the battery pack 30 .

[0041] A preferred embodiment of the present invention: the middle frame assembly 2 also includes a connection seat 25 and a connection head 26 arranged outside the frame body 20, the connection seat 25 is a female socket structure, and the connection head 26 is a charging and discharging head connected to the PCB 310 through a wire.

[0042] A preferred embodiment of the present invention: a receiving groove for receiving the connector 26 is provided on one side of the frame body 20 .

[0043] A preferred embodiment of the present invention: a switch 23 and an interface 24 are provided on the side of the frame body 20 , and the interface 24 is fixed by the other side of the card slot 21 and communicated with the PCB 310 .

[0044] The universal contact connection is adopted, which does not require wires and dot processing, and reduces electrical losses.

[0045] The above are only preferred embodiments of the technical solution of the utility model, and do not limit the patent scope of the technical solution of the utility model. All equivalent structural changes made by using the contents of the technical solution description and drawings of the utility model under the conception of the technical solution of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the technical solution of the utility model.
