[0028] With the increasing global attention to environmental protection and sustainable development, new energy vehicles have become an important development direction for the automotive industry. Battery packs are important components of new energy vehicles, and the performance of battery packs plays a key role. Among them, whether the battery pack has abnormal noise has also become an important topic in battery pack development. Due to the need to reduce costs, the thickness of the bottom guard plate of the battery pack is getting thinner and thinner, and the accompanying abnormal noise of the bottom guard plate is also occurring.

[0029] Based on this, the present application proposes a battery bottom guard plate 10, which can effectively reduce abnormal noise of the bottom guard plate.

[0030] Reference below Figure 1-Figure 3A battery bottom guard plate 10 according to an embodiment of the present utility model is described.

[0031] like Figure 1-Figure 3 As shown, the battery bottom guard plate 10 according to the embodiment of the utility model comprises a bottom guard plate body 1 , and a plurality of mounting holes 11 evenly spaced apart are arranged on the outer periphery of the bottom guard plate body 1 .

[0032] Exemplarily, the battery includes a battery shell, the battery shell includes a battery side panel or a battery frame, and the bottom guard plate body 1 can be installed on the battery side panel or the battery frame by screwing. Specifically, the battery side panel or the battery frame is provided with a fixing hole corresponding to the mounting hole 11, and the screw can pass through the mounting hole 11 and the fixing hole, thereby fixing the bottom guard plate body 1 to the battery side panel or the battery frame.

[0033] Furthermore, a mounting structure 12 is also provided on the bottom guard plate body 1 , and a plurality of mounting structures 12 are provided, and the plurality of mounting structures 12 are spaced apart along the length direction and / or width direction of the bottom guard plate body 1 .

[0034] like Figure 1-Figure 3 As shown, the mounting structure 12 is arranged in the middle area of ​​the bottom guard plate body 1. Thus, by fixing the middle area of ​​the bottom guard plate body 1, the structural strength of the middle area of ​​the bottom guard plate body 1 can be effectively strengthened. The arrangement of multiple mounting structures 12 can further improve the structural strength of the middle part of the bottom guard plate body 1. Thus, the bottom guard plate body 1 with improved structural strength can effectively reduce abnormal noise.

[0035] Exemplarily, the mounting structure 12 may be a fixed block having an assembly hole disposed thereon, and a fixed connection with the structure on the upper portion of the bottom guard plate body 1 is achieved through the assembly hole, and this application does not impose any limitation thereto.

[0036] According to the battery bottom guard plate 10 of the embodiment of the utility model, by arranging a plurality of mounting structures 12 in the middle area of ​​the bottom guard plate body 1, the structural strength of the middle area of ​​the bottom guard plate body 1 can be effectively strengthened, and the arrangement of the plurality of mounting structures 12 can further improve the structural strength of the middle part of the bottom guard plate body 1. Therefore, the bottom guard plate body 1 with improved structural strength can effectively reduce abnormal noise.

[0043] Optionally, multiple convex ribs or multiple concave ribs are provided. By providing multiple convex ribs or multiple concave ribs, the structural strength of the bottom guard plate can be better improved. Furthermore, multiple convex ribs or multiple concave ribs are arranged in a matrix, thereby evenly improving the structural strength of the bottom guard plate.

[0044] Optionally, the plurality of convex ribs or the plurality of concave ribs extend along the length direction of the bottom guard plate body 1 .

[0045] like Figure 2-Figure 3 As shown, the convex ribs are arranged in two columns along the length direction of the bottom guard plate body 1 and in six rows along the width direction of the bottom guard plate body 1. The plurality of convex ribs extend along the length direction of the bottom guard plate, thereby better improving the structural strength of the bottom guard plate.

Three fixed columns are arranged in the length direction of the bottom guard plate body 1, and each fixed column includes six mounting structures 12. A fixed row is arranged in the middle of the width direction of the bottom guard plate body 1, and the six mounting structures 12 of each fixed column are symmetrically arranged on both sides of the fixed row.
