Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and in particular to a connecting component and a battery pack assembly. Background Art

[0002] Energy storage batteries mainly refer to batteries used to store electrical energy in power generation equipment such as solar and wind power. With the continuous development of the new energy industry, the technology in the field of lithium batteries is also constantly being updated. Nowadays, the application fields of lithium batteries are becoming more and more extensive. In addition to being suitable for electric vehicles, electric bicycles, electronic equipment and other tools, in recent years, lithium batteries have also gradually been converted to outdoor energy storage systems.

[0003] Currently, when users use outdoor energy storage batteries, they generally connect multiple energy storage battery packs in series and parallel to change the voltage. The upper and lower battery packs are stacked together and installed by relying on their own weight. Although this stacking combination makes the battery pack more beautiful, this combination is extremely unstable. In some other technologies, the battery pack adopts a stacking design, but the upper and lower battery packs rely on the gravity of the upper battery pack to achieve installation. This battery pack combination is extremely unstable. After the battery pack is hit by external force, the position of the battery packs will shift, and the battery pack at the top may even fall.

[0004] Therefore, how to avoid the deviation of the stacking state of battery packs is a technical problem that needs to be solved urgently in this field. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0023] See also Figures 1 to 2 , Figure 1 A three-dimensional diagram of a preferred embodiment of the connecting member of the present utility model; Figure 2 This is an exploded view of the connecting component and battery pack assembly of the utility model.

[0024] like Figures 1 to 2 As shown, at least one embodiment provides a connecting member comprising: a connecting portion 1; and mounting portions 2 fixed on both sides of the connecting portion 1 and adapted to abut against a battery pack or a fixing surface; wherein the mounting portion 2 is provided with at least one assembly hole 21, each located on a flank of the mounting portion 2. For a mounting portion 2, if more than two battery packs need to be stacked and fixed, two assembly holes 21 are provided; if only one battery pack is fixed, only one assembly hole 21 is provided. The assembly hole 21 on one mounting portion 2 is a round hole, and the assembly hole 21 on the other mounting portion 2 is an elongated hole.
