The connector assemblies 20, explosion-proof assembly 30, and side panels 10 are slidably assembled to form a case 100 having a cylindrical chamber. The number of connector assemblies 20, explosion-proof assembly 30, and side panels 10 can be selected as needed, thereby enabling the case 100 to be assembled into different sizes, improving versatility to meet a variety of needs. The sliding assembly method facilitates installation and disassembly, improves production assembly efficiency, and reduces costs. The connector assembly 20 is formed with a slide rail 21 extending longitudinally within the case 100 to facilitate the installation and replacement of the electronic device 200. The explosion-proof assembly 30 includes an explosion-proof valve 31 connecting the inside and outside of the case 100, which can quickly respond to the need for rapid smoke, air, and heat dissipation when unexpected situations such as thermal runaway occur. In addition, the modular case 100 can be processed using small basic equipment, facilitating flexible production line adjustments and reducing the cost of single-piece processing.

[0046] The number of connector assemblies 20, explosion-proof assemblies 30, and side panels 10 can be set as needed. In this embodiment, the housing 100 is composed of a plurality of side panels 10, one connector assembly 20, and one explosion-proof assembly 30 that are slidably assembled, with the connector assembly 20 and the explosion-proof assembly 30 located on two adjacent side walls of the housing 100. In other embodiments, the housing 100 can be composed of a plurality of side panels 10, one connector assembly 20, and two explosion-proof assemblies 30 that are slidably assembled, with the two explosion-proof assemblies 30 located on two adjacent side walls of the housing 100, with one explosion-proof assembly 30 and the connector assembly 20 located on the same side wall of the housing 100.

[0047] The sliding assembled battery box further includes a bottom plate 40 and a top cover, wherein the bottom plate 40 is arranged at the bottom of the box body 100 and the top cover is arranged at the top of the box body 100. The side plate 10 is detachably connected to the bottom plate 40, and the side plate 10 is detachably connected to the top cover, and the detachable connection can be a screw connection.

[0049] In this embodiment, adjacent side panels 10 are plugged into each other in the longitudinal direction. During assembly, the corresponding side panels 10, connector assemblies 20, and explosion-proof assemblies 30 are selected according to the required dimensions and then slid together in the longitudinal direction, enabling quick assembly and high adaptability. In other embodiments, adjacent side panels 10 are plugged into each other in the transverse direction.

[0050] Specifically, a groove 101 is provided on one edge of the side panel 10, and a protrusion 102 is provided on the other edge of the side panel 10. The protrusion 102 of one side panel 10 is longitudinally plugged into the groove 101 of the other side panel 10. The groove 101 longitudinally extends through the upper and lower ends of the side panel 10, and the protrusion 102 is at the same height as the side panel 10 along the longitudinal direction.

[0051] In this embodiment, the opening of the groove 101 faces the inner side of the box body 100, so that the appearance of the box body 100 is neat. In other embodiments, the opening of the groove 101 can face the outer side of the box body 100.

[0052] An adhesive layer is sandwiched between the outer wall of the protrusion 102 and the inner wall of the groove 101, thereby sealing the protrusion 102 and the groove 101. The adhesive layer can be formed by solidifying a liquid adhesive. Before assembly, the liquid adhesive is applied to the inner wall of the groove 101. The fluidity of the liquid reduces the friction when the protrusion 102 is inserted into the groove 101, thereby achieving rapid assembly. After the protrusion 102 and the groove 101 are plugged in, the liquid adhesive solidifies to form an adhesive layer, thereby sealing the protrusion 102 and the groove 101 tightly.
