[0025] This specific embodiment is a lithium battery power bank casing that is easy to disassemble and assemble, and its structural schematic diagram is shown below. Figures 1-9 As shown, the device includes an upper cover 15 and a bottom box 16. The upper cover 15 matches the bottom box 16. The bottom box 16 has first screw holes 9 near the four corners of its rear side wall. The upper cover 15 has a button 1 near the right side of its front wall and an indicator light 2 near the center of its front wall. A USB interface 3 is installed near the top between the upper cover 15 and the right side wall of the bottom box 16. A Type-C interface 4 is installed near the center between the upper cover 15 and the right side wall of the bottom box 16. A power input interface 5 is installed near the bottom between the upper cover 15 and the right side wall of the bottom box 16. An input magnetic interface 11 is installed near the center of the rear side wall of the bottom box 16. A mounting base 17 is installed on the rear side of the bottom box 16. A latching mechanism is provided between the bottom box 16 and the mounting base 17. A magnetic latch 10 is installed on the rear side wall of the bottom box 16. An output magnetic interface 12 is installed on the front wall of the mounting base 17. The output magnetic interface 12 matches the magnetic latch 10.

[0026] When using this technical solution, the circuit board module needs to be placed inside the bottom box 16 to ensure the stability and safety of the circuit board module.

[0027] like Figures 5-9 As shown, the buckling mechanism includes two L-shaped buckles 13, which are symmetrically fixed on the front wall of the fixing base 17. The rear side wall of the bottom box 16 is symmetrically provided with buckle groove plates 18. The front wall of the buckle groove plates 18 penetrates the bottom box 16 and extends into the bottom box 16. The buckle groove plates 18 match the L-shaped buckles 13. The rear side wall of the fixing base 17 is provided with several evenly distributed second screw holes 14.

[0028] The L-shaped buckle 13 ensures the stability of the output magnetic interface 12 when closed, preventing accidental drops or breakage during carrying.

[0029] The upper cover 15 and the bottom box 16 are respectively provided with evenly distributed positioning buckles 6 near the edge on the opposite side. Multiple positioning buckles 6 are carefully designed on the edges of the upper cover 15 and the bottom box 16. These positioning buckles 6 effectively fix the upper and lower shells together tightly to prevent the upper cover 15 and the bottom box 16 from separating accidentally.

[0030] In addition, screw holes 7 are symmetrically arranged on the inner rear wall of the bottom box 16, and limit plates 8 are symmetrically fixedly connected to the inner rear wall of the bottom box 16. The limit plates 8 effectively improve the friction coefficient between the battery packs by increasing the friction force, so that the battery pack does not shake, and also helps to enhance the overall structural stability of the box.

[0031] The fixing seat 17 has symmetrical fixing holes 19 on its front wall. The inner wall of the fixing hole 19 is tapered. The fixing seat 17 can be installed on furniture through the fixing hole 19.

[0032] Working principle: In this technical solution, button 1 can display the remaining power of the power bank after being pressed and held for about 1 second. Indicator light 2 can effectively display the power status of the power bank, making it convenient for users to check the remaining power. USB interface 3 and Type-C interface 4 ensure stable power transmission. Power input interface 5 is tightly connected to the built-in power cord.

[0033] The structure is stable. The fixing magnetic buckle 10 can make the fixing base 17 connect with the magnetic and lock firmly, making it less prone to breakage and shaking. The input magnetic interface 11 uses magnetic force to tightly connect the power bank and the output magnetic interface 12, which simplifies the plugging and unplugging operation. Moreover, due to the magnetic connection method, physical wear caused by frequent plugging and unplugging is reduced, and the service life of the interface is extended.

[0034] In addition, the output magnetic interface 12 is tightly attached to the bottom box 16 by magnetic force, without the need for screws, adhesives or other physical fixing methods, which ensures stable current transmission between the input magnetic interface 11 and the power bank, and facilitates the disassembly and replacement of the power bank, providing convenience for users.

[0035] Multiple positioning buckles 6 are carefully designed along the edges of the top cover 15 and the bottom box 16. These positioning buckles 6 effectively and tightly fix the upper and lower shells together, preventing the top cover 15 and the bottom box 16 from accidentally separating. In addition, the magnetic position is precisely designed to be vertical to the top to facilitate the smooth use of the power cord. The magnetic connection makes the separation operation simple and quick. Compared with the traditional plug-in connection, the input magnetic interface 11 and the output magnetic interface 12 will not be worn during connection and separation, extending the product's service life. At the same time, the user only needs to bring the interface close, and the magnetic force will automatically guide the two to connect correctly without visually aligning the socket, improving the convenience of connection. In addition, the addition of the retaining plate 18 makes it less likely to break or fall off.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
