[0004] In summary, lithium battery boxes have drawbacks such as components being easily damaged and inconvenience during use. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing lithium battery boxes, such as easy damage to components and inconvenience in use, and provides a lithium battery box assembly with enhanced structural strength and ease of use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lithium battery box assembly, including

[0008] Top shell;

[0009] The lower shell is snapped together with the upper shell.

[0010] The upper and lower shells are detachably connected via a connecting component.

[0011] A sealing ring is used to seal the connection between the upper and lower shells.

[0012] Anti-slip ridges, which are connected to the surface of the upper shell;

[0013] Anti-slip grooves are located on one side of the surface of the lower shell.

[0014] A recessed groove is located on the other side of the surface of the lower shell.

[0015] A plug-in fixing component is connected to the upper and lower shells.

[0016] Place the connector and connect it to the lower shell;

[0017] The reinforcing components are connected to both the upper and lower shells.

[0018] The lithium battery case is assembled from an upper and lower shell to form a single outer casing. The enclosed cavity within the upper and lower shells houses the lithium battery. The upper and lower shells are initially positioned and fixed by snap-fit ​​connections, and then further secured by connecting components to prevent separation and battery loosening. This design allows for easy removal and maintenance of the battery's interior. The upper and lower shells are connected by a sealing ring to improve sealing and achieve waterproofing and dustproofing. A plug-in fixing component is used to install and secure the electronic components that provide power output. The design is adaptable to repeated insertion and removal; anti-slip protrusions are placed on the surface of the upper shell, while anti-slip grooves and recessed grooves are placed on the surface of the lower shell. This increases the friction when the lithium battery box is picked up, stored, and inserted / removed, making it easier to hold and preventing slippage. It also enhances the resistance to breakage, further improving insertion / removal efficiency and ease of use. A connector is placed to connect to the outside of the lower shell, allowing for quick insertion and placement in the desired location for easy storage and preventing loss. Reinforced components connect the upper and lower shells, increasing their structural strength and overall overall strength, preventing the lithium battery box from breaking. This achieves the effects of improving the structural strength of the lithium battery box components to prevent damage, facilitating lithium battery maintenance, providing high sealing performance, enhancing anti-slip strength, facilitating quick insertion and removal, simplifying placement and storage, and improving the overall structural strength of the lithium battery box.

[0019] Preferably, several anti-slip protrusions are provided and evenly distributed on the surface of the upper shell, with the two ends of the anti-slip protrusions close to the sides of the upper shell. The lithium battery box has a rectangular structure, and the anti-slip protrusions are long-span lines extending from one side of the longer side of the lithium battery box to the other. Several anti-slip protrusions are evenly distributed and arranged, thereby increasing the anti-slip area and fracture resistance of the lithium battery box. This achieves the effects of enhancing hand grip friction, preventing deformation, and improving ease of use.

[0020] Preferably, the anti-slip groove is located near the side of the lower shell, and its depth is close to the thickness of the lower shell. The groove wall has a wavy shape. Positioning the anti-slip groove near the side of the lower shell surface deepens the groove, preventing interference with battery placement. This increased depth also facilitates stable finger placement and allows for easy gripping of the lithium battery case from the lower shell. The wavy groove wall enhances both anti-slip properties and aesthetics. This further improves the overall friction, deformation resistance, and ease of use of the lithium battery case.

[0021] Preferably, the connector includes a left limiting plate and a right limiting plate, which are arranged mirror images of each other. Each of the opposite sides of the left and right limiting plates has a limiting groove, and each of the opposing sides of the left and right limiting plates is connected to a reinforcing rib, which is connected to the lower shell. The mirrored arrangement of the left and right limiting plates allows the two limiting grooves to form a slot for placement and insertion, facilitating the placement and storage of the lithium battery box. Simultaneously, the reinforcing ribs on the left and right limiting plates enhance the connection strength between the left and right limiting plates and the lower shell, preventing breakage of the left and right limiting plates. This achieves the effect of rapid placement and storage of the lithium battery box while maintaining structural strength.

[0022] Preferably, the recessed groove is positioned between the left and right limiting plates, and its depth is shallower than that of the anti-slip groove. This recessed groove is positioned between the left and right limiting plates to increase the grip friction of the lower casing, and its shallow depth prevents interference with the placement of the battery within the lower casing. This further enhances the ease of use and structural strength of the lithium battery box.

[0023] Preferably, the plug-in fixing assembly includes a fixing bracket and a fixing baffle. Both the fixing bracket and the fixing baffle are connected to the inner wall of the upper shell, and the fixing baffle is sleeved with the fixing bracket. The fixing bracket in the plug-in fixing assembly is connected to the upper shell to reserve a position for installing output electronic components for the lithium battery box. The fixing baffle is sleeved with the fixing bracket and connected to the upper shell to stabilize the fixing bracket and electronic components at the plug-in point. This further improves the structural connection stability.

[0024] Preferably, several connecting components are provided, including a fixing bolt, an upper connecting post, a lower connecting post, and a fixing post. The upper connecting post connects to the inner cavity of the upper shell, the lower connecting post connects to the inner cavity of the lower shell, the upper connecting post and the lower connecting post are inserted into each other, the fixing post is inserted into the upper connecting post, the fixing bolt is inserted into the lower connecting post, and the fixing bolt passes through the fixing post and is threadedly connected to the upper connecting post. The upper and lower shells are connected by several sets of connecting components. The upper connecting post in the connecting components connects to the upper shell, and the lower connecting post connects to the lower shell and is arranged opposite to each other. When the upper and lower shells are connected, the upper connecting post is inserted into the end face of the lower connecting post and is inserted into the fixing post. The fixing bolt is inserted through the outside of the lower shell into the lower connecting post and passes through the fixing post and is threadedly connected to the upper connecting post to completely fix the upper and lower shells, preventing the upper and lower shells from shifting and the internal lithium battery from shaking. It also facilitates disassembly and maintenance. The fixing post improves the connection stability of the upper and lower connecting posts and the load-bearing strength of the threaded connection. This achieves the effect of improving the connection strength between the structures and the ease of assembly and disassembly.

[0025] Preferably, the reinforcing assembly includes several stiffeners, namely, stiffener one and stiffener two. Stiffener one is connected to the bottom surface and one side wall of the lower shell inner cavity, and stiffener two is connected to the bottom surface and the other side wall of the lower shell inner cavity. Stiffener one in the reinforcing assembly connects to the bend joint between the bottom surface of the lower shell inner cavity and a pair of opposite side walls, and stiffener two connects to the bend joint between the bottom surface of the lower shell inner cavity and another opposite side wall, preventing the side plate of the lower shell from breaking under stress. This achieves the effect of enhancing structural strength and preventing deformation of the lithium battery box.

[0026] The beneficial effects of this utility model are: improving the structural strength of the lithium battery box assembly to prevent damage; facilitating lithium battery maintenance; providing high sealing performance; improving the anti-slip strength of the lithium battery box; facilitating quick insertion and removal and use; facilitating placement and storage; improving ease of assembly and disassembly; and preventing deformation of the lithium battery box.
