At present, lithium batteries are various in use scenes as standby power supplies, the lithium batteries are batteries which use non-aqueous electrolyte solution and take lithium metal or lithium alloy as a negative electrode material, and the lithium metal has very high requirements on the environment for processing, storage and use due to the very active chemical characteristics of the lithium metal, so that the lithium batteries become mainstream at present along with the development of scientific technology; nowadays, lithium cell group is applied to in various environment, wherein weak adverse circumstances, waterproof construction's design is indispensable, and protective housing is installed to current lithium cell group more, but the water-proof effects of these shells is relatively poor, though be provided with the rubber pad in shell chamber door department, nevertheless can still appear the infiltration when meetting special weather, the emergence of phenomenon such as the inside humidity of box, and the normal discharge of light person influence lithium ion battery group can lead to lithium ion battery group's damage when serious to the potential safety hazard appears.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a waterproof structure of a battery pack shell, which has the advantage of playing a waterproof effect through structural change of the shell, and solves the problems that the existing lithium battery pack is provided with a plurality of protective shells, but the waterproof effect of the shells is poor, and although a rubber pad is arranged at the door of the shell, the phenomena of water seepage, humidity inside a box body and the like can still occur in special weather, the normal discharge of the lithium battery pack is influenced by a light person, the lithium battery pack can be damaged possibly in a serious case, and potential safety hazards can occur.

In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a group battery shell waterproof construction, includes shell, sealed pad, upper cover and PG plug, the surface top of shell is equipped with first connecting plate, the upper cover has been put to the top lid of shell, the opening part terminal surface of upper cover is equipped with the second connecting plate, run through on first connecting plate and the second connecting plate and seted up the connecting hole, the centre gripping is fixed with sealed pad between the second connecting plate of shell and upper cover.

Preferably, a limiting hole is formed in the sealing gasket in a penetrating mode, and the position and the size of the limiting hole are matched with those of the connecting hole.

Preferably, the first connecting plate on the shell is positioned below the end face at the opening of the shell.

Preferably, a handle is fixed to the top end surface of the upper cover.

Preferably, one side surface of the shell is provided with two PG plugs, and the two PG plugs are symmetrically distributed on the shell.

Compared with the prior art, the utility model has the beneficial effects that: through setting up the shell, first connecting plate on the shell is located shell opening part terminal surface below, shell opening edge adopts stair structure, the ladder height is at 10mm, and the centre gripping is fixed with sealed the pad between the first connecting plate of shell and the second connecting plate of upper cover, when using, sealed pad can play primary sealed effect between first connecting plate and second connecting plate, and the opening edge of shell is higher than first connecting plate, can prevent that water from permeating the shell between first connecting plate and the second connecting plate, and then prevent that lithium ion battery group from weing the damage.
