Problems solved by technology

At the same time, due to the close arrangement of multiple batteries, the structure is compact, and it is impossible to straighten a certain inclined battery
[0006] To sum up, once a battery is misaligned in the packaging structure of a large number of existing battery packs, it is difficult to eliminate the coaxiality between the fixing holes of the upper and lower brackets and the cylindrical battery, no matter what kind of automation or correction machine is used in the later stage. The deviation is too large, and the encapsulation is unsuccessful or bad.

Embodiment 1

[0048] A battery pack packaging structure, such as Figure 1-4 As shown, it includes a first fixing plate 2 and a second fixing plate 4; the first fixing plate 2 is provided with a plurality of first fixing holes 21, and the second fixing plate 4 is provided with a plurality of One fixing hole 21 corresponds to the second fixing hole 23; the first fixing hole 21 and the second fixing hole 23 are through holes, and the first fixing hole 21 and the corresponding second fixing hole 23 coaxial arrangement. The battery pack includes a plurality of cylindrical batteries 3, the upper surface of the first fixing plate 2 is bonded and fixed with the first sealing plate 1 when the upper ends of the battery pack are placed in the first fixing holes 21, and the second fixing plate 2 is fixed on the upper surface of the battery pack. The lower surface of the plate 4 is bonded and fixed with the second sealing plate 5 when the lower end of the battery pack is placed in the second fixing ho...

Embodiment 2

[0052] A battery pack packaging structure, similar to Embodiment 1, the difference is that the second positioning hole 23 on the second fixing plate 4 is a blind hole, the first fixing hole 21 on the first fixing plate 2 is a through hole, and the first fixing hole 21 is a through hole. The upper surface of the plate 2 is fixed with the first sealing plate 1, but the lower surface of the second fixing plate 4 is no longer provided with the second sealing plate 5, only at the position of the second positioning hole of the second fixing plate 4 and the first sealing plate 1 Open the battery exposure hole 11 directly.

[0053] During encapsulation, glue is applied on the inner wall of the first positioning hole 21 and the second positioning hole 23, and the outer wall of the battery 3, and then the first fixing plate 2 and the second fixing plate 4 are kept at a certain distance with a bracket, and the first fixing plate 2 and the second fixing plate 4 are kept at a certain distan...

Abstract

The invention discloses a battery pack packaging structure and a packaging method. The battery pack packaging structure comprises a first fixing plate and a second fixing plate, wherein a plurality of first fixing holes are formed in the first fixing plate; a plurality of second fixing holes corresponding to the first fixing holes are formed in the second fixing plate; the first fixing holes and / or the second fixing holes are through holes; when the upper surfaces of the first fixing plates are arranged in the corresponding first fixing holes at the upper ends of the batteries of the battery pack and the lower surfaces of the second fixing plates are arranged in the corresponding second fixing holes at the lower ends of the batteries of the battery pack, seal plates are fixing outside the fixing plates in which the through holes are formed. According to the battery pack packaging structure and the packaging method, all batteries can be packaged once regardless of the number of the batteries and the correcting process is not needed; meanwhile, the accuracy of the size of the assembled battery pack can be guaranteed, and the finally-formed battery pack is stable and firm in structure.

Description

technical field [0001] The invention relates to the field of battery assembly structures, in particular to a battery pack packaging structure and a packaging method. Background technique [0002] Power batteries are the core components of electric vehicles, and cylindrical batteries have been widely used in electric vehicles due to their high energy density in the overall structure. When electric vehicles want to achieve long range, they need more batteries. The energy contained in the cylindrical battery is certain, which means that the car will need more cylindrical lithium batteries to run farther. When assembling cylindrical lithium batteries, the more batteries there are, the more difficult it is to package the battery pack. [0003] Chinese patent CN201020242094.0 discloses a battery fixing and connecting device, which includes a lower bracket and an upper bracket assembled on the lower bracket. A number of buckle arms with buckle holes are opened. The upper bracket...
