Description
Technical Field
The utility model relates to the technical field of battery pack assembly, in particular to a pressure-resistant separator for a battery pack.
Background
The battery pack is mainly applied to the field of electric automobiles and the field of energy storage, a protective baffle is required to be installed when a plurality of layers of battery cores in the battery pack are packaged, the weight of a shell is required to be strictly controlled due to the energy density requirement of the battery pack, and the protective baffle used in the prior art is a smooth baffle with larger thickness or a protective baffle which consists of an upper thin baffle, a lower thin baffle and a buffer energy absorption layer positioned in the middle and is related to a patent of CN212659633U (battery pack protective plate, a battery pack assembly and a vehicle); although the protective separator represented by the latter has a somewhat reduced weight, there is still a certain room for improvement in terms of weight reduction, and the protective separator has a complicated structure and high manufacturing cost.
The utility model provides a pressure-resistant separator for a battery pack, which solves the technical problems.
Disclosure of Invention
The utility model provides a withstand voltage baffle for battery package, includes baffle body, connecting bridge, connect through the slope between the baffle body connect, adjacent interval formula from top to bottom between the baffle body.
Preferably, the pressure-resistant separator for the battery pack is arranged in a splayed manner, wherein the inclination directions of the adjacent connecting bridges are opposite.
Preferably, in the pressure-resistant separator for a battery pack, the free edge portions of the two separator bodies at the edge are provided with L-shaped corner support portions.
Preferably, the pressure-resistant separator for the battery pack is characterized in that a thickened bearing part is arranged at the joint of the separator body and the corner supporting part.
Preferably, the pressure-resistant separator for a battery pack has opposite extending directions of the corner support portions on both sides.
Preferably, the pressure-resistant separator for the battery pack is characterized in that an extension supporting plate is arranged at the connecting line of the separator body and the connecting bridge.
Preferably, the pressure-resistant separator for a battery pack, wherein a plurality of holes are formed in the plate surface of the separator body 1.
The advantages are as follows:
the main structure of the pressure-resistant partition board is formed by the partition board body and the connecting bridge, and the weight of the partition board is greatly reduced by the grooves in the main structure, and meanwhile, the consumption of raw materials is reduced; the connecting bridge arranged in the splayed shape and corner supporting parts on two sides of the partition plate ensure the pressure resistance of the partition plate, and the connecting bridge can play a role in energy absorption through micro deformation to play a certain role in buffering. The arrangement of the extension supporting plate increases the stress area of the partition plate and improves the pressure resistance of the partition plate; the design of the holes further improves the overall light weight of the separator, ensures that the whole battery pack is ventilated and uniformly radiated, and avoids the phenomenon of local overheating. The integrated structure is convenient for quick forming and has simple structure.
