Specific embodiment
The application is described in further detail below by specific embodiment and with reference to accompanying drawing.Described in text
"front", "rear", "left", "right", " on ", D score with the battery bag in accompanying drawing as reference.
As depicted in figs. 1 and 2, the embodiment of the present application provides a kind of battery bag, including casing 1, some battery modules group
Fixed mechanism 2, cover plate 3 and some battery modules group 4.Casing 1 is the element of battery bag, for accommodating battery mould
Group 4.Casing 1 includes bottom surface 10 and side wall 12, and side wall 12 is set perpendicular to bottom surface 10 around bottom surface 10, makes the structure of casing 1
Into a semi-closed structure for open top.The exterior contour of casing 1 can be the cube of standard, it is also possible to adopt as needed
With increasingly complex shape, for example, some stair-stepping structures are constituted by side wall 12, so as to reduce casing 1 stage by stage at one
Size (referring to Fig. 3) on direction, additionally, also casing 1 can be divided into multiple by way of setting dividing plate 14 in casing 1
Separate space, is easy to subregion management and control, improves security performance.
The quantity of the battery modules group 4 that the inside of casing 1 is accommodated can be determined according to the size of casing 1 and structure.
Referring to Fig. 4, each battery modules group 4 includes some battery modules 40, and battery modules 40 include major opposing side 400 and narrow side
402, as shown in figure 5, battery modules 40 stack arrangement, and stacking direction while and bottom surface along perpendicular to the direction of major opposing side 400
10 is perpendicular.So, the battery modules quantity in each battery modules group 4 can be true according to the high flexible of side wall 12 of casing 1
It is fixed, so that ensureing the height of the battery bag remaining space for being located at the top of battery modules group 4 can be less than the thickness of battery modules 40,
For the height of battery modules 40, the thickness of battery modules 40 is very small, therefore battery bag can be significantly increased
Space availability ratio, lifted energy density.
Battery modules 40 are stacked after forming battery modules group 4 to be needed to be located at the master of the top in each battery modules group 4
Cover plate 3 is covered on side 400, on the one hand the effect of cover plate 3 is the battery modules group 4 below protection, on the other hand, battery mould
Group 40 can be expanded along stacking direction in use, and if parectasis, the change in size mistake of battery modules group 4
Greatly, it is possible to have influence on and the normal of other parts of the top of battery modules group 4 is arranged in battery bag uses, therefore, cover plate 3
The degrees of expansion of battery modules group 4 can effectively be suppressed.Cover plate 3 needs to be made using the material of sufficient intensity, when necessary, also
Reinforcement 30 can be set on cover plate 3, further increase the intensity of cover plate 3.
As shown in fig. 6, the quantity of battery modules group's fixed mechanism 2 is consistent with battery modules group 4, battery modules 4 heaps of group are treated
It is folded complete and cover cover plate 3 after, all battery modules 40 in same battery modules group 4 and cover battery modules group 4
Cover plate 3 be just fixed in the lump on bottom surface 10 commonly through battery modules group's fixed mechanism 2, complete battery modules group's 4
It is fixed.
Battery modules group's fixed mechanism 2 can have various structures, as long as can be fixed with bottom surface 10 and limit battery simultaneously
The movement of module 40 and cover plate 3.Battery modules group's fixed mechanism 2 in the present embodiment includes some fixation kits, is
The movement of battery modules 40 and all directions of cover plate 3 can fully be suppressed, as shown in Figure 1 and Figure 5, this implementation
Battery modules group's fixed mechanism 2 in example includes multiple fixation kits, and preferred amount is four, using this four fixation kits just
Battery modules group 4 and cover plate 3 can be fixed by the corner of battery modules 4 projection on bottom surface 10 of group respectively.
In the present embodiment, fixation kit is not direct entirety self-contained battery module group 4, but directly self-contained battery mould
Each battery modules 40 in group 4, as shown in Figure 4 and Figure 5, the narrow side 402 of the battery modules 40 that the present embodiment is provided
On be provided with by fixed part 404, coordinated by fixed part 404 and fixation kit and fix.
Fixation kit includes bolt 20, nut 22 and pad 24, and bolt 20 mutually fixes with bottom surface 10, screw thread 20 and casing
1 can independently manufacture, and be threadably secured afterwards or be fixed on bolt 20 on casing 1 by other fixed forms.It is more simple
Just mode is that bolt 20 is embedded into bottom surface 10 during casing 1 is molded, and treats that casing 1 is manufactured while completion just
Bolt 20 can be fixed in bottom surface 10 in the lump.
Fixed via 404a is provided with fixed part 404, fixed via 404a extends along the direction perpendicular to bottom surface 10,
Bolt 20 pass through fixed via 404a so that battery modules 40 cannot along the radial direction of fixed via 404a, that is, parallel to
The direction movement of bottom surface 10.Meanwhile, fixed perforation 32 is provided with cover plate 3, bolt 20 is then passed through all of fixed via
After 404a, pad 24 can be afterwards then passed through by lower section through fixed perforation 32, top and the nut 22 of bolt 20 pass through screw thread
It is connected, battery modules 40 and cover plate 3 is limited between bottom surface 10 and nut 22, it is impossible to along the axle of bolt 20
To, that is, moved perpendicular to the direction of bottom surface 10.In the process, nut 22 is required to after being threadedly coupled with bolt 20
Apply certain pretightning force to cover plate 3, the effect of pad 24 is damaged to prevent cover plate 3 from abrasion occurring with nut 22,
There is provided certain buffer spring simultaneously.Thus, battery modules 40 and cover plate 3 are parallel to bottom surface 10 and perpendicular to bottom surface 10
Direction cannot move again so that realize to battery modules group 4 and cover plate 3 fixation.
The battery bag that the embodiment of the present application is provided is added significantly to the space availability ratio of battery bag, improves energy close
Degree.
The preferred embodiment of the application is the foregoing is only, the application is not limited to, for the skill of this area
For art personnel, the application can have various modifications and variations, based on any modification, equivalent substitution and improvements that the application is made
Deng should be included within the protection domain of the application.
