[0004] In summary, lithium battery boxes have drawbacks such as being difficult to assemble and maintain, and being inconvenient to use. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing lithium battery boxes, such as difficult assembly and maintenance, and inconvenient use, and provides a lithium battery box assembly structure that is easy to assemble, maintain, and use.

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

[0007] A lithium battery box assembly structure, 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] The socket assembly has a positioning groove at one end of both the upper and lower shells, and the socket assembly is connected to the positioning groove.

[0013] Anti-slip grooves are located at the other end of the lower shell;

[0014] Place the connector and connect it to the lower shell;

[0015] The reinforcing components are connected to both the upper and lower shells.

[0016] The lithium battery box is assembled from an upper and lower shell to form a single outer casing, creating an enclosed cavity for housing 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. It is also detachable for easy maintenance of the battery box's interior. The upper and lower shells are connected by a sealing ring to improve sealing and achieve waterproofing and dustproofing. A socket assembly is used for external power output, and the socket assembly is positioned and connected via a positioning slot. The lithium battery case is secured to facilitate insertion and removal. Anti-slip grooves are positioned opposite the positioning grooves on the lower shell, preventing the lithium battery case from slipping during insertion and removal, thus improving insertion efficiency and ease of use. This prevents the connector from connecting to the outside of the lower shell, allowing for quick insertion and placement of the connector in a suitable location for easy storage and preventing loss of the lithium battery case. Reinforcing components connect to the upper and lower shells, increasing their structural strength and overall rigidity, preventing the lithium battery case from breaking. The overall design achieves the following benefits: improved lithium battery placement stability, easier lithium battery maintenance, high sealing performance, easy quick insertion and removal, convenient storage, and enhanced overall structural strength.

[0017] Preferably, the upper shell has a connecting groove, into which the sealing ring engages, and the lower shell has a connecting retaining ring that engages with the connecting groove. The upper shell inserts the sealing ring through the connecting groove to connect with the retaining ring in the lower shell, so that the retaining ring presses against the sealing ring during connection, achieving a tight seal between the upper and lower shells. This ensures the sealing performance of the lithium battery box and thus extends its service life.

[0018] 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 convenience of assembly and disassembly.

[0019] Preferably, the positioning groove includes an upper positioning groove and a lower positioning groove. The upper positioning groove is located on the end face of the upper shell, and the lower positioning groove is located on the end face of the lower shell. The socket assembly includes a connecting seat and a slot plate. The slot plate is connected to the connecting seat. The upper end of the connecting seat is inserted into the upper positioning groove, and the lower end of the connecting seat is inserted into the lower positioning groove. The positioning groove includes an upper positioning groove formed in the upper shell and a lower positioning groove formed in the lower shell. One side of the connecting seat in the socket assembly is fitted into the upper positioning groove, and the other side is fitted into the lower positioning groove, so that the slot plate connected to the connecting seat can be fixed in the upper and lower shells. The slot plate is provided with several slots to output lithium battery power. This achieves the effect of improving the structural connection positioning and connection strength.

[0020] 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.

[0021] Preferably, the reinforcing assembly includes several upper stiffening plates, lower stiffening plates, and ribs. The upper stiffening plates are connected to the bottom surface and side walls of the upper shell's inner cavity, the ribs are connected to the upper stiffening plates, and the lower stiffening plates are connected to the bottom surface and side walls of the lower shell's inner cavity. The upper stiffening plates in the reinforcing assembly are connected at the bends in the bottom surface and side walls of the upper shell's inner cavity, and the lower stiffening plates are connected at the bends in the bottom surface and side walls of the lower shell's inner cavity, preventing the upper and lower shells from breaking under stress. The upper stiffening plates of the upper shell are connected as a single unit by the ribs in a grid pattern to enhance structural strength and prevent deformation of the upper shell under stress. This achieves the effect of enhancing structural strength and preventing deformation of the lithium battery box.

[0022] Preferably, the upper shell has several pre-drilled holes, and a mounting plate is connected to the inner cavity of the upper shell. The mounting plate has a mounting slot for the power display element, and the position of the mounting slot for the power display element matches the position of the pre-drilled holes. The upper shell has several regularly arranged pre-drilled holes, and the mounting plate has a pre-drilled mounting slot for the power display element to facilitate the stable assembly of the power display module later. The pre-drilled holes are reserved holes for the indicator lights of the power display module. This improves the practicality of the lithium battery box.

[0023] The beneficial effects of this utility model are: the lithium battery box improves the stability of lithium battery placement; facilitates lithium battery maintenance; has high sealing performance; facilitates quick insertion and removal and use; facilitates placement and storage; improves the overall structural strength of the lithium battery box; improves the connection strength between structures and the convenience of assembly and disassembly; prevents lithium battery box deformation; and improves the practicality of the lithium battery box.
