Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, each execution mode of the present utility model is explained in detail.But, persons of ordinary skill in the art may appreciate that in each execution mode of the utility model, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following execution mode and amendment, each claim of the application technical scheme required for protection also can be realized.
First execution mode of the present utility model relates to a kind of containment vessel of soft-package battery.
As shown in Figure 1, this containment vessel is formed with battery cavities, and the sidewall 2 of battery cavities has towards the bending part of battery cavities inside; Wherein, when soft-package battery 1 is placed in battery cavities, soft-package battery 1 is held at least part of bending part, and the sidewall edge 21 of battery cavities is away from soft-package battery 1.Wherein, sidewall edge 21 refers to the trimming position of the sidewall 2 of battery cavities.This trimming position is top edge and the lateral edges of each sidewall 2 of battery cavities.As shown in Figure 2, bending part is multiple convex closures 3, and the processing technology of convex closure 3 is comparatively simple.
In present embodiment, the sidewall 2 due to battery cavities has the convex closure 3 towards battery cavities inside; When soft-package battery 1 is placed in battery cavities; soft-package battery 1 is held in convex closure 3; thus make the sidewall edge 21 of battery cavities away from soft-package battery 1; namely the sidewall edge 21 avoided due to battery cavities directly contact with soft-package battery 1 and and cause the burr of its sidewall edge to puncture the phenomenon of the battery core of soft-package battery, thus reach the object of protection soft-package battery 1.
Further, as shown in Figure 3, the height of each convex closure 3 is less than 0.2 millimeter (distance as shown in B in Fig. 3).If the excessive height of convex closure 3, can larger space be taken, the size of complete machine is had a certain impact; Be designed to be less than 0.2 millimeter by the height of convex closure 3, thus not only make to form gap between soft-package battery 1 and sidewall 2, the size of convex closure 3 is less simultaneously, impacts hardly the size of complete machine.
Further, each convex closure 3 is less than 0.25 millimeter (distance as shown in the A in Fig. 3) from the distance of the sidewall edge 21 of battery cavities, wherein, this sidewall edge 21 is top edge and the lateral edges of each sidewall 2 of battery cavities, distance shown in A in Fig. 3 is the distance of convex closure 3 from the top edge of battery cavities sidewall 2, and convex closure 3 is not shown from the distance of the lateral edges of battery cavities sidewall 2.If convex closure 3 is excessive from the distance of the sidewall edge 21 of battery cavities, now because soft-package battery has certain pliability, sidewall edge 21 still likely contacts with soft-package battery 1, the burr of sidewall edge 21 still likely can puncture the battery core of soft-package battery 1, cause battery leakage even to set off an explosion; So convex closure 3 is less than 0.25 millimeter from the distance of the sidewall edge 21 of battery cavities, can ensures that sidewall edge 21 is away from soft-package battery 1 further, thus avoid the burr of sidewall edge 21 can puncture the battery core of soft-package battery 1.
Second execution mode of the present utility model relates to a kind of containment vessel of soft-package battery.Second execution mode is roughly the same with the first execution mode, and main distinction part is: in the present embodiment, and bending part is multiple raised line.
In present embodiment, bending part is multiple raised line.Wherein, the set-up mode of raised line can, for being parallel or perpendicular to battery cavities bottom surface, simplicity of design, be easy to realize.
Such as this tab parallel is in battery cavities bottom surface, if raised line to arrange length identical with the side wall length of battery cavities, then a raised line is set on sidewall sidewall edge can be made away from soft-package battery, any restriction is not done to the number of raised line herein.
The utility model the 3rd execution mode relates to a kind of containment vessel of soft-package battery, and as shown in Figure 4, present embodiment is roughly the same with the first/bis-execution mode, and main distinction part is: in the present embodiment, and bending part is the turn-up portion of sidewall.
In present embodiment, bending part is the turn-up portion 4 of sidewall, and wherein, the turn-up portion 4 of sidewall is for being positioned at the outside turnover part of the sidewall edge parallel with battery cavities bottom surface; Preferably, the turn-up portion 4 of sidewall also comprises the outside turnover part be positioned at the sidewall edge of battery cavities plane perpendicular.
In addition, turn-up portion 4 is circular arc, and simplicity of design is easy to realize, and arcuate surface is smooth not easy to wear.
The utility model the 4th execution mode relates to a kind of containment vessel of soft-package battery.4th execution mode is roughly the same with the 3rd execution mode, and main distinction part is: in the present embodiment, and as shown in Figure 5, turn-up portion 4 is inclined-plane knuckle.
In present embodiment, because inclined-plane knuckle supports between sidewall and soft-package battery, thus make the sidewall edge of battery cavities away from soft-package battery, avoid the burr of sidewall edge to cause wearing and tearing to soft-package battery.
Persons of ordinary skill in the art may appreciate that the respective embodiments described above realize specific embodiment of the utility model, and in actual applications, various change can be done to it in the form and details, and do not depart from spirit and scope of the present utility model.
