Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery packaging, and more specifically, it relates to an explosion-proof lithium battery protective case. Background Art

[0002] Lithium batteries are a type of battery with lithium metal or lithium alloy as the negative electrode material and using non-aqueous electrolyte solutions. However, with the development of science and technology and the widespread use of digital products such as mobile phones and laptop computers, lithium batteries have been widely used in these products due to their excellent performance. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have now become the mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. In order to store lithium batteries for a long time, special packaging boxes are generally required for packaging to minimize the wear of lithium batteries.

[0003] The existing packaging boxes (as shown in Figure 1 ) are generally made of polyethylene and sealed at both ends. Such packaging boxes are squeezed during transportation, and during the use of lithium batteries, if used improperly, the lithium batteries may explode. Due to the insufficient strength of the polyethylene material, it will be damaged when impacted, resulting in the flying of packaging box fragments and causing harm to the human body. Moreover, the packaging box is square, which is not convenient for operators to fix it. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an explosion-proof lithium battery protective case that is convenient to fix.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An explosion-proof lithium battery protective case includes a main body with a cavity inside. It is characterized in that: the main body is made of metal material, an opening communicating with the cavity is provided at one end of the main body, a connecting plate one is fixedly connected to the other end of the main body, a cover body is provided on the opening, and the cover body is detachably connected to the main body.

[0007] The cover body includes a main board and partitions arranged around the main board. The partitions extend into the opening. A connecting plate two is provided on the main board. At least two fixing holes are provided on the end faces of the connecting plate one and the connecting plate two. The connecting plate one and the connecting plate two are arranged flush.

[0008] Sealing glue is filled between the partition and the main body.

[0009] The present utility model is further configured such that: the partition plate and the main board are integrally formed, two sets of connection holes are symmetrically formed on the partition plate, the second connecting plate is disposed between the two docking holes, docking holes corresponding to the connection holes are formed on the main body, threads are formed in both the connection holes and the docking holes, and screws are disposed in the docking holes.

[0010] The present utility model is further configured such that: a through hole communicating with the cavity is formed on the end face of the main board, and the through hole is disposed below the second connecting plate.

[0011] The present utility model is further configured such that: the first connecting plate is welded to the outer wall of the main body, and the second connecting plate is welded to the end face of the main board.

[0012] The present utility model is further configured such that: antirust coatings are provided on the outer walls of the main body, the cover body, the first connecting plate, and the second connecting plate.

[0013] The present utility model is further configured such that: the sealant is made of silicone rubber.

[0014] Compared with the deficiencies of the prior art, the beneficial effects of the present utility model are as follows:

[0015] By changing the material to a metal material, the strength of the lithium battery packaging box is enhanced, preventing the fragments of the packaging box from splashing when the lithium battery explodes and causing potential safety hazards. Further, silicone rubber is filled between the cover body and the main body, enhancing the sealing performance of the lithium battery packaging box and having a certain waterproof function. Moreover, connecting plates are provided at both ends of the main body, facilitating the fixation of the main body through the fixing holes on the connecting plates.
