Description

Technical Field

[0001] The utility model relates to the field of lithium batteries, in particular to a protective shell for a lithium battery pack which is easy to assemble. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and a non-aqueous electrolyte solution. With the development of science and technology, lithium batteries have become mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Among them, lithium-ion batteries do not contain metallic lithium and are rechargeable. Regardless of whether it is a lithium metal battery or a lithium-ion battery, due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements.

[0003] To improve the protection of lithium batteries, the Chinese patent "Anti-destruction protective shell for lithium batteries" (patent number: CN214706103U) solves the problem that elastic pads are prone to displacement, thereby affecting the protective effect of the elastic pads on lithium batteries. However, this device only provides protection by stacking external objects. When encountering an impact, the impact force will still be directly transmitted to the internal lithium battery, which does not provide complete protection and leads to low practicality.

[0004] For example, a patent for an anti-destruction protective shell for lithium batteries (Announcement No.: CN217035820U) includes a protective shell body, wherein telescopic rods are fixedly mounted on the four sides of the interior of the protective shell body, shock-absorbing springs are fixedly mounted on the telescopic rods, and aluminum heat-conducting plates are fixedly mounted on opposite sides of the two telescopic rods. A rubber pad is fixedly mounted on the interior of the protective shell body, and adsorption magnets are provided on the four sides of the exterior of the protective shell body. Connection holes are provided on the four sides of the exterior of the protective shell body. When the lithium battery encounters a large impact, the telescopic rods and shock-absorbing springs can effectively offset the impact force, preventing the lithium battery from colliding with the inner wall of the shell due to the impact. At the same time, the aluminum heat-conducting plate that clamps the lithium battery can also quickly transfer heat from the lithium battery, reducing the temperature of the lithium battery and increasing the battery's service life.

[0005] The aforementioned patent increases the lifespan of lithium batteries by utilizing a shock-absorbing spring and an aluminum heat-conducting plate. However, in daily use, the cover plate is bolted to the protective housing body, requiring additional tools to install the bolts during lithium battery installation. This reduces assembly efficiency and makes assembly inconvenient. Therefore, it is necessary to invent a protective housing for lithium battery packs that is easy to assemble to address this issue.
