[0035] Please refer to Figures 1 and 2. This utility model provides a portable energy storage power supply 100, including a mounting housing 1. The mounting housing 1 includes a top cover 11, a bottom plate 12, and a side plate 13. The top cover 11, the bottom plate 12, and the side plate 13 form a receiving cavity 10 for mounting an energy storage component. A first connecting structure 2 is provided between the side plate 13 and the top cover 11, and a second connecting structure 3 is provided between the side plate 13 and the bottom plate 12. The side plate 13 includes two opposing first side plates 131 and two opposing second side plates 132. A third connecting structure 4 is provided between the first side plates 131 and the second side plates 132. At least one of the first connecting structure 2, the second connecting structure 3, and the third connecting structure 4 is a snap-fit ​​structure. The energy storage component includes a plurality of battery cells.

[0036] Please refer to Figures 1 to 3. In this embodiment, the mounting housing 1 is basically rectangular, composed of an upper cover 11, a bottom plate 12, and side plates 13. The interior of the mounting housing 1 is a hollow receiving cavity 10, used to accommodate several cells and other components of the energy storage module. The side plates 13 include two opposing first side plates 131 and two opposing second side plates 132. The upper cover 11, bottom plate 12, and side plates 13 can be made of engineering plastics. Engineering plastics can improve the strength of the mounting housing 1 and protect the components inside the receiving cavity 10. Furthermore, engineering plastics have strong creep resistance. Engineering plastics are lightweight, which can reduce the overall weight of the portable energy storage power supply and improve the user experience. Of course, the above is only an example; the specific materials can be determined according to actual needs, and this utility model does not impose any limitations.

[0037] In some embodiments, the first connecting structure 2 may be a snap-fit ​​structure or the like. For example, the first connecting structure 2 is a snap-fit ​​structure, and the upper cover 11 is detachably connected to the side plate 13. When assembling the upper cover 11 and the side plate 13, the snap-fit ​​structure of the first connecting structure 2 allows them to be joined together without the need for screws, achieving rapid assembly. Furthermore, it facilitates quick disassembly when either is damaged or when the components within the receiving cavity 10 need repair or replacement.

[0038] In some embodiments, the second connecting structure 3 can be a snap-fit ​​structure. For example, the second connecting structure 3 is a snap-fit ​​structure, and the base plate 12 is detachably connected to the side plate 13. When assembling the mounting housing 1, the snap-fit ​​structure of the second connecting structure 3 allows the base plate 12 and the side plate 13 to be joined together first, without the need for screws, achieving rapid assembly. Finally, the top cover 11 is joined to the side plate 13 to complete the assembly of the entire mounting housing 1. When any component of the mounting housing 1 is damaged or needs repair or replacement within the receiving cavity 10, it can be quickly disassembled and replaced.

[0039] In some embodiments, the third connecting structure 4 may be a snap-fit ​​structure. For example, the third connecting structure 4 is a snap-fit ​​structure. When assembling the side panel 13, one of the first side panels 131 is snap-fitted to the second side panel 132, the other side of the second side panel 132 is snap-fitted to another first side panel 131, and then both sides of the last second side panel 132 are snap-fitted to the two first side panels 131 respectively. This completes the assembly of the side panel 13 without the need for additional screws or tools, reducing workload and improving work efficiency.

[0040] During assembly, the portable energy storage power supply 100 of this utility model is assembled by fastening the independent first side plate 131 and second side plate 132 together through a third connecting structure 4. The independent base plate 12 is then fastened to the side plate 13 through a second connecting structure 3, and the top cover 11 is fastened to the side plate 13 through a first connecting structure 2. This eliminates the need for frequent use of screwdrivers and other tools, improving assembly efficiency. Furthermore, the fastening method reduces the use of screws, preventing screw loss that could reduce the connection stability of the housing 1, and minimizing the impact of screws on internal electrical components, thus enhancing the user experience of the portable energy storage power supply 100.

[0041] In some embodiments, the portable energy storage power supply 100 further includes an inverter assembly 6, which is installed within the receiving cavity 10. Specifically, the inverter assembly 6 is connected to the inner wall of the upper cover 11. When assembling the portable energy storage power supply 100, the upper cover 11 is usually the last part to be assembled, at which point numerous components are installed within the receiving cavity 10. By connecting the inverter assembly 6 to the inner wall of the upper cover 11, the entire portable energy storage power supply 100 can be assembled directly by fastening the upper cover 11 to the side plate 13 via the first connecting structure 2, eliminating the need to separately assemble the inverter assembly 6 within the receiving cavity 10, thus avoiding component crowding and improving the portability of the assembly.

[0042] Please refer to Figures 4, 5 and 10. In some embodiments, the first connecting structure 2 includes a plurality of first fasteners 21 disposed on the edge of the upper cover 11 and a plurality of first positioning members 22 disposed on the side plate 13 opposite to one end of the upper cover 11. The first fasteners 21 are detachably connected to the first positioning members 22.

[0043] In some embodiments, the first fastener 21 is a cantilevered fastener, disposed on the edge of the upper cover 11. Exemplarily, there are eight first fasteners 21. Three first fasteners 21 are disposed on each of the longer sides of the upper cover 11, and two first fasteners are disposed on the shorter side of the upper cover 11, which can evenly distribute the force on each individual first fastener 21. Correspondingly, a consistent number of first positioning members 22 are disposed on the side plate 13. The addition of the first positioning members 22 facilitates positioning during assembly, improves assembly efficiency, and allows the first positioning members 22 to cooperate with the first fasteners 21 to secure the upper cover 11 and the side plate 13 together.

[0044] In some embodiments, the first latching member 21 includes a first latching portion 211 protruding from the edge of the upper cover 11 to connect to the first positioning member 22. The first positioning member 22 is provided with a first opening 221 opposite to the first latching portion 211 so that the first latching portion 211 passes through the first opening 221 and abuts against the first positioning member 22.

[0045] Please continue referring to Figures 5 and 10. In some embodiments, the structure of the first latching part 211 can be L-shaped, claw-shaped, etc. For example, the first latching part 211 protrudes from the edge of the upper cover 11 in an L-shape, facilitating connection with the first positioning member 22. When assembling the upper cover 11 and the side plate 13, by aligning the first latching part 211 of the upper cover 11 with the first positioning member 22 and applying force, the first latching part 211 passes through the first opening 221. The L-shaped protrusion of the first latching part 211 will hook against the first positioning member 22, thus achieving a secure connection between the upper cover 11 and the side plate 13. Of course, the above is only an example, and the specific structural design can be determined according to actual needs. This utility model does not impose any limitations here.

[0046] Please refer to Figures 6 to 9. In some embodiments, the second connection structure 3 includes a plurality of second fasteners 31 disposed on one end of the side plate 13 opposite to the bottom plate 12, and a plurality of second positioning members 32 correspondingly disposed on the bottom plate 12. The second fasteners 31 are detachably connected to the second positioning members 32.

[0047] In some embodiments, the number of second fasteners 31 is ten. Three second fasteners 31 are spaced apart on the first side plate 131, and two second fasteners 31 are spaced apart on the second side plate 132. This distributes the force evenly on each second fastener 31, extending its service life. Correspondingly, a consistent number of second positioning elements 32 are provided on the base plate 12. Through the second positioning elements 32, the second fasteners 31 and the second positioning elements 32 can be quickly positioned and connected during installation without the need for other tools, completing the assembly of the housing 1 and improving assembly efficiency.

[0048] Please continue to refer to Figures 7 and 9. In some embodiments, the second latching member 31 includes a second latching portion 311 exposed on the edge of the side plate 13. The side of the second latching portion 311 facing away from the receiving cavity 10 has a first groove 3111. The side of the second latching portion 311 facing the receiving cavity 10 and the side of the second latching portion 311 facing away from the receiving cavity 10 have a height difference to form a first engaging surface 3112. The length of the end of the second positioning member 32 near the side plate 13 is less than the length of the end of the second positioning member 32 away from the side plate 13, and forms a second engaging surface 321. The second positioning member 32 can abut against the first groove 3111.

[0049] In this embodiment, the length of the end of the second latching part 311 facing the receiving cavity 10 is greater than the length of the end facing away from the receiving cavity 10, thus forming a first latching surface 3112 with a slope. When assembling the base plate 12 and the side plate 13, the first latching surface 3112 matches the second latching surface 321, and the second latching part 311 can slide along the second positioning member 32, and finally abut the second positioning member 32 in the first groove 3111, thereby fastening the base plate 12 and the side plate 13.

[0050] Please refer to Figures 10 and 11. In some embodiments, the third connection structure 4 includes a plurality of third fasteners 41 disposed on the edge of the first side plate 131 along the height direction, and a plurality of third positioning members 42 disposed on the edge of the second side plate 132 along the height direction. The third fasteners 41 are perpendicular to the third positioning members 42, and the third fasteners 41 are detachably connected to the third positioning members 42.

[0051] In this embodiment, there are twelve third fasteners 41, with three spaced apart along the edge of the first side plate 131 in the height direction. Correspondingly, the second side plate 132 also has the same number of third positioning elements 42 spaced apart in its height direction. Through the design of the third fasteners 41 and the third positioning elements 42, the first side plate 131 and the second side plate 132 can be quickly assembled.

[0052] Please continue referring to Figures 10 and 11. In some embodiments, the third latching member 41 includes a third latching portion 411 protruding from the first side plate 131. The third latching portion 411 is L-shaped. The third positioning member 42 has a second opening 421 facing the first side plate 131 for the third latching portion 411 to pass through. When assembling the first side plate 131 and the second side plate 132, by aligning the third latching portion 411 with the second opening 421, the third latching portion 411 can pass through the second opening 421, and the barb abuts against the third positioning member 42, thus connecting the first side plate 131 and the second side plate 132.

[0053] In some embodiments, a connecting rod 5 is provided at each of the four corners of the receiving cavity 10, the bottom plate 12 is provided with a first positioning hole 121 communicating with the receiving cavity 10, the first side plate 131 is provided with a second positioning hole 133 corresponding to the first positioning hole 121 at one end near the top cover 11, and the top cover 11 is provided with a third positioning hole 111 communicating with the receiving cavity 10. After the connecting rod 5 passes through the second positioning hole 133, its two ends can respectively abut against the first positioning hole 121 and the third positioning hole 111.

[0054] Please refer to Figures 2 and 3. To further improve the connection stability of the mounting housing 1, four connecting rods 5 are provided in the receiving cavity 10, located at the four corners. The four corners of the base plate 12 are provided with first positioning holes 121 connecting to the receiving cavity 10, and the four corners of the top cover 11 are provided with third positioning holes 111 connecting to the receiving cavity 10. The two ends of the connecting rods 5 are connected to the top cover 11 and the base plate 12 respectively by screws, which can improve the connection stability of the mounting housing 1 and prevent it from loosening under external impact, thus avoiding damage to the components inside the receiving cavity 10.

[0055] Please refer to Figure 10. Furthermore, a second positioning hole 133 is provided on each of the two first side plates 131. After the connection between the bottom plate 12 and the side plate 13 is completed, the connecting rod 5 is passed through the second positioning hole 133 and the first positioning hole 121 in sequence. Finally, the top cover 11 and the side plate 13 are connected together. The third positioning hole 111 can further assist in positioning, improve assembly efficiency, and improve the connection stability of the mounting housing 1.
