Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model
Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
Obtained all other embodiment is put, the range that the utility model is protected is belonged to.
In the description of the present invention, it should be understood that term " center ", " lateral ", " length ", " width ", " height
Degree ", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outside", " side " etc. refer to
The orientation or positional relationship shown be based on orientation or positional relationship shown in FIG. 1, be merely for convenience of description the utility model and
Simplify description, rather than the equipment of indication or suggestion meaning or element must have a particular orientation, with specific orientation construction
And operation, therefore should not be understood as limiting the present invention.
As shown in Figure 1, the utility model provides a kind of pack case body, including box body 1 and end cap 2, box body 1 is hollow
Structure, inner cavity are used for placing battery group, and the side of box body 1 has the opening being put into for battery pack, and end cap 2 is removably connected to
Opening offers the threading hole 3 of connection external loading on end cap 2.
The cassette bottom face of box body 1 is an integral structure with box body ontology in the present invention.
Cassette bottom face and box body ontology setting is into a single integrated structure, and box body 1 is only put into battery pack, Ci Zhongjie there are open at one end
Structure reduces the seam quantity of pack case body, and waterproof performance is good, is put into after battery pack when doing water-proofing treatment again, need to only consider end
The sealing of the seaming position of lid 2 and box body 1, simplifies operating process, reduces human cost；Since box body 1 is one
Body structure keeps its more resistant.
As optional embodiment, end cap 2 includes base 21 and convex block 22, as shown in Fig. 2, base 21 is in convex block 22
Staircase structural model, end cap 2 are fastened on box body 1 by convex block 22.Wherein the side wall of convex block 22 and the inner wall of box body 1 offset, convex
Bottom surface 23 and the battery pack of block 22 offset.
End cap 2 is arranged to staircase structural model, and fixed effect is more preferable when connecting end cap 2 with box body 1, i.e., not only leans on colloid
Cohesive force base 21 is connect with box body 1, moving radially between end cap 2 and box body 1 is also limited by convex block 22, reaches double
Fixed effect again, and then leakproofness is effectively ensured.
The side wall of convex block 22 and the inner wall of box body 1 offset, and bottom surface and the battery pack of convex block 22 offset, can be to convex block 22
The whole circle of the inner wall of outer wall and box body 1 seals, and waterproofness is more preferable, while the contact surface of end cap 2 offsets with battery pack, and battery pack is consolidated
It is scheduled in box body 1, battery pack will not be made the work of wobble effects battery or to influence electricity in box body 1 due to the movements such as shaking, moving
Pond service life.
As preferred embodiment, the height of convex block 22 is more than or equal to the height of base 21.
Such structure is set, after end cap 2 is fixed with box body 1, is avoided since 22 height of convex block is too small, by external force
When effect, the case where convex block 22 is routed up out of box body 1.
As preferred embodiment, end cap 2 is hollow structure.
End cap 2 is hollow structure, when gluing is fixed, in addition to will end cap 2 and 1 open end of box body it is fixed other than, it is also necessary to wearing
Handled at string holes 3, around 3 surrounding gluing of threading hole, allow part colloid get into middle vacancy prevent water from threading hole 3 into
Enter in box body 1, while reducing the weight of pack case body entirety, keeps battery pack lighter in use.
As optional embodiment, box body 1 and the bottom edge of base 21 are fixed by marine glue.
Preferably, marine glue is hot melt adhesive.
It is cheap since hot melt adhesive has waterproof performance, and colloid can soften when temperature reaches 80 ° or so, it can will
End cap 2 is separated with box body 1 in the case where operating without destroying, while room temperature is in solid state, and performance is stablized, and facilitates storage
It deposits；It is non-toxic and tasteless, meet the requirement of environment-friendly type colloid.
In the present embodiment, box body 1 is cuboid or cylindrical body.
1 type shape of box body carrys out blow molding production by the type shape of battery pack, can be blow molded into according to the battery pack size, shape difference
Box body of corresponding size, can be cuboid or cylindrical body, and when use is in the majority with cuboid-type shape.
Preferably, pack case body is manufactured using high-density polyethylene material.
The abrasion resistance, heat resistance and cold resistance of high-density polyethylene material are preferable, and chemical property is stablized, and mechanical strength is good；
At room temperature, any organic solvent, the corrosion of acid and alkali resistance and various salts are not dissolved in.
As optional embodiment, 1 outer surface of box body is provided with label or LOGO pattern layer, convenient for users to reading product
