Abstract
Description
Technical Field
[0001] This utility model relates to a battery box protective plate. Background Technology
[0002] Battery protection plates are a crucial component of battery protection in modern electric vehicles. Their airtightness is paramount, ensuring no leaks after assembly. Furthermore, the battery protection assembly is a welded system of individual parts, and in automotive manufacturing, it's integrated with the chassis using screws. It's a specially designed barrier, requiring meticulous attention to airtightness; otherwise, product performance will be compromised. For assembly purposes, existing protection plates have clearance notches. To ensure airtightness after welding, a sealing cover is welded to the notch, followed by PVC coating. The original system involved numerous individual components and multiple production steps (stamping followed by welding), increasing costs. Summary of the Invention
[0003] The problem to be solved by this utility model is a battery box protective plate with high airtightness requirements. This battery box protective plate has a simple production process and low cost.
[0004] The technical solution provided by this utility model is: a battery box protective plate, including a protective plate body, with flanges on both sides of the protective plate body. Each flange is composed of two sections, and each section of the flange is formed by bending after zero-gap punching, and a lug is formed between the flanges.
[0005] The flange is L-shaped.
[0006] This invention features a simple structure, a simple production process, and low cost. While meeting performance requirements, it improves production efficiency, reduces production costs, and optimizes product quality, making production more efficient and economical.

[0011] The present invention will be further described below with reference to the accompanying drawings.
[0012] See Figures 1 to 4The present invention includes a protective plate body 1, and the protective plate body 1 has L-shaped flanges 2 on both sides. Each flange 2 is composed of two sections. Each flange section is formed by punching with zero gap and bending. Lugs 3 are formed between the flanges.
[0013] This utility model eliminates the welded sealing cover plate, employing a zero-gap punched notch 4. The edge of the notch 4 is flush with the surface of the flange 2. The flange 2 is formed by bending after zero-gap punching, eliminating the need for a welded sealing cover plate. The protective plate is directly welded to other parts of the battery box body, and the lugs, flange, and other edges form a sealed connection with the battery box body. This utility model improves production efficiency, reduces production costs, and optimizes product quality while meeting performance requirements, making production more efficient and economical.
