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 first fixing holes 21 corresponding to the first fixing plate 4. A second fixing hole 23 corresponding to one fixing hole 21 ; the first fixing hole 21 and the second fixing hole 23 are both through holes, and the first fixing hole 21 and the second fixing hole 23 corresponding to it are provided 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 1 is fixed. The lower surface of the plate 4 is bonded and fixed with the second sealing plate 5 when the lower ends of ...

Embodiment 2

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

[0053] During packaging, apply glue to the inner walls of the first positioning hole 21 and the second positioning hole 23 and the outer wall of the battery 3, and then use a bracket to keep the first fixing plate 2 and the second fixing plate 4 at a certain distance, and the first fixing plate 2 and the second fixing plate 4. The two fixing plates 4 are arranged in ...

Abstract

The invention discloses a battery pack packaging structure and a packaging method. The packaging structure of the battery pack includes a first fixing plate and a second fixing plate; the first fixing plate is provided with a plurality of first fixing holes, and the second fixing plate is opened with a plurality of fixing holes corresponding to the first fixing plate. The holes are one-to-one corresponding second fixing holes; the first fixing holes and / or the second fixing holes are through holes, and the upper surface of the first fixing plate is placed on the corresponding first fixing holes at the upper ends of the batteries of the battery pack. In the fixing holes and the lower surface of the second fixing plate, when the lower ends of the batteries of the battery pack are placed in the corresponding second fixing holes, a sealing plate is fixed outside the fixing plate with through holes. The invention can ensure that no matter how many batteries there are, all the batteries can be packaged at one time without correction, and at the same time, the dimensional accuracy of the assembled battery pack can be ensured, and the finally formed battery pack has a stable and reliable 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] The power battery is the core component of the electric vehicle, and the cylindrical battery has been widely used in the electric vehicle due to the high energy density of the overall structure. When electric vehicles want to achieve long-range battery life, they need more batteries. The energy contained in the cylindrical battery is certain, which means that the car will need a larger number of cylindrical lithium batteries to run further. When assembling cylindrical lithium batteries, the more the number of batteries, the more difficult it is to package the battery pack. [0003] Chinese patent CN201020242094.0 discloses a battery fixing connection device, which includes a lower bracket and an upper bracket assembled on the lower bracket, wherein the lower bracket includes a low...
