Effect.
Reference picture 1, Fig. 2 and Fig. 4, in the present embodiment, the lithium battery encapsulation housing include the square aluminum hull of both ends open
10 and fixed two metal ends 20 (can be the materials such as stainless steel or aluminium alloy) for being covered in the square both ends of aluminum hull 10, metal
There is the groove 21 towards the square inner recess of aluminum hull 10, and each side wall of groove 21 presses close to square aluminum hull 10 respectively on end cap 20
Corresponding side wall；Sealant 30 is clamped between the end face of square aluminum hull 10 and metal end 20, sealant 30 is around groove 21
Set, i.e., sealant 30 makes to keep sealing between the end face of square aluminum hull 10 and metal end 20.By setting groove 21, make lithium
Cell package housing can show the port progress just positioning that groove 21 is caught in square aluminum hull 10, be more convenient for pacifying in assembling
Dress, while can more facilitate the setting of sealant 30.
The lithium battery encapsulation housing of the present embodiment, the two-port of square aluminum hull 10, shape are covered by using metal end 20
Into the housing of all-metal, because metal end 20 is non-aging, therefore during the service life of lithium battery, can keep well
The waterproof sealing effect of lithium battery encapsulation housing, ensure the safe to use of lithium battery；Meanwhile metal end 20 and square aluminum hull 10
It is metal material, more unified in appearance luster and metal-like, profile is overall more attractive in appearance, also will not be due to severe ring
The influence in border cause two outward appearance difference it is obvious；In addition, for compared to plastic cement end cap injection molding, the production of metal end 20
Technique is simpler, and cost and difficulty are lower.
Because the wall thickness of square aluminum hull 10 will not do too thick, and the long side of the port of square aluminum hull 10 is longer, because
This, in fact it could happen that the situation for deformation of outwards arching upward, it can so cause the long side of the port of square aluminum hull 10 and sealant 30 wrong
Position, causes seal failure.For this problem, reference picture 2, Fig. 3, Fig. 5 and Fig. 6, the present embodiment is further in metal end 20
Spacing flange 22 is provided with the edge corresponding to the long side of the port of square aluminum hull 10, the spacing flange 22 is bonded square aluminum
The outer surface of shell 10, and sealed adhesive slot 23 is formed between the lateral wall of spacing flange 22 and groove 21；Two long sides of sealant 30
In sealed adhesive slot 23, the long side of the port of square aluminum hull 10 is stuck in corresponding sealed adhesive slot 23.By using square
The long side of the port of aluminum hull 10 is stuck in sealed adhesive slot 23, and spacing flange 22 is bonded the outer surface of square aluminum hull 10, that is, limits
Position flange 22 has been adjacent to the long side of the port of square aluminum hull 10, prevents the long side of the port of square aluminum hull 10 outwards to arch upward
Deformation, in this way, preferably ensure that the stability of the waterproof sealing of lithium battery encapsulation housing.
Further, since metal end 20 is provided with spacing flange 22, the outer wall of spacing flange 22 and groove 21 forms sealing
The structure of glue groove 23, the structure of the sealed adhesive slot 23 causes the bulk strength of metal end 20 to be lifted, in this way, ensuring compliance with intensity
In the case of it is required that, further metal end 20 can be designed it is thinner, to reduce cost of material.
In the present embodiment, the sealant 30 in sealed adhesive slot 23 can be colloidal binder or sealing strip etc..If fluid sealant
Sealant 30 in groove 23 uses colloidal binder, then sealant 30 can be set by coating technique, due to sealed adhesive slot 23
Set, the efficiency of gluing can be improved and reduce the loss of glue.If the sealant 30 in sealed adhesive slot 23 uses sealing strip, whole
Individual sealant 30 can use the sealing ring for being socketed in the outside of groove 21.
Preferably, reference picture 2 is to Fig. 4, and in the present embodiment, each edge of the end face of square aluminum hull 10 is equipped with installation
Screw (not shown), each edge of metal end 20 are spirally connected admittedly by the installation screw of screw 24 and square aluminum hull 10
It is fixed.Certainly, square aluminum hull 10 can also take other modes to be fixed with metal end 20.The square aluminum hull 10 of the present embodiment
It is preferred that use aluminium alloy extruded shaping.
Further, referring to Figures 1 and 2, the input of waterproof is installed on the metal end 20 in two metal ends 20
Joint 40 and out splice going splice 50；The outer end of input adapter 40 is used to connect photovoltaic panel, and the inner is used to connect lithium battery encapsulation housing
In lithium battery group；The outer end of out splice going splice 50, which is used to connect, to be loaded, the lithium electricity that the inner is used to connect in lithium battery encapsulation housing
Pond group.Certainly, a little indicator lamps, controlling switch can also be set on the metal end 20 of input adapter 40 and out splice going splice 50 by installing
Deng.
The utility model also proposes a kind of lithium battery pack, and the lithium battery pack includes lithium battery encapsulation housing and at least one peace
Lithium battery in the lithium battery encapsulation housing, concrete structure reference above-described embodiment of the lithium battery encapsulation housing, by
Whole technical schemes of above-mentioned all embodiments are employed in this lithium battery pack, therefore at least there is the technical side of above-described embodiment
All beneficial effects caused by case, this is no longer going to repeat them.
Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model,
Every equivalent structure change under inventive concept of the present utility model, made using the utility model specification and accompanying drawing content
