Abstract
Description
A silicone foam cushioning pad for a new energy vehicle battery pack Technical Field
[0001] This utility model relates to the field of new energy vehicle battery technology, and in particular to a silicone foam cushioning pad for new energy vehicle battery packs. Background Technology
[0002] Silicone foam cushioning pads are a type of high-molecular elastomer material made from silicone as the base material through a foaming process. They are specifically designed for new energy vehicle battery packs and possess excellent cushioning, heat insulation, flame retardancy, sealing, and weather resistance properties. Their closed-cell structure and high resilience can effectively absorb the stress generated by the battery pack during vibration, impact, and thermal expansion and contraction, ensuring battery safety and extending its service life. However, there are many types of silicone foam, and different types of silicone foam have significant differences in hardness and cushioning performance.
[0003] In scenarios where improved buffering performance between battery modules is required, a larger gap is usually reserved between adjacent battery modules to accommodate thicker soft silicone foam. This design can effectively absorb high-frequency vibrations and significantly enhance the buffering effect. However, while providing buffering, excessively thick soft silicone foam will significantly reduce its support performance. When new energy vehicles are driving at high speeds or braking suddenly, the battery modules are prone to displacement due to insufficient foam support. This displacement may cause the electrical connectors inside the module to loosen or break due to uneven stress, which may lead to safety hazards such as short circuits, overheating, or even fires. Summary of the Invention
[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a silicone foam cushioning pad for a new energy vehicle battery pack, comprising a first silicone foam and a second silicone foam, with a reinforcing plate fixedly disposed between the first and second silicone foams. A first locking block is fixedly installed on the right side of the first silicone foam, and a first locking groove is formed on the left side of the reinforcing plate. The first locking block and the first locking groove are movably engaged. A second locking block is fixedly installed on the left side of the second silicone foam, and a second locking groove is formed on the right side of the reinforcing plate. The second locking block and the second locking groove are movably engaged. A limiting groove is formed through the front side of the reinforcing plate, and the limiting groove is movably engaged with the limiting block. A main ventilation hole is formed at the top of the reinforcing plate, and a secondary ventilation hole is formed through the left side of the reinforcing plate. The main ventilation hole and the secondary ventilation hole are connected, and the main ventilation hole is connected to the limiting groove.
[0005] As an improvement to the above technical solution, a fixed card slot is provided in the middle of the front side of both the first card block and the second card block, and the limiting card block is movably engaged with the fixed card slot.
[0006] As an improvement to the above technical solution, there are multiple reinforcing plates, and the thicknesses of the multiple reinforcing plates are all different.
[0007] As an improvement to the above technical solution, the outer top edges of both the first and second locking slots are designed with rounded corners.
[0008] As an improvement to the above technical solution, the first card block and the second card block are misaligned.
[0009] The beneficial effects of this utility model are as follows: With the cooperation of the reinforcing plate and the limiting block, the buffering performance between the two battery modules is ensured, while the overall support and heat dissipation performance of the buffer pad is also improved. When the new energy vehicle is driving at high speed or braking suddenly, the buffer pad provides sufficient support while maintaining the buffering performance, making it difficult for the battery module to shift. This stability ensures that the electrical connectors inside the module are subjected to uniform force, avoiding loosening or breakage, thereby effectively preventing safety hazards such as short circuits, overheating, or even fires.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0016] Referring to Figure 1, in Figure 1, a points to the front view and b points to the right side view. The above views are only used to understand the scheme.
[0017] Please refer to Figures 1-4. This utility model provides a technical solution: a silicone foam cushioning pad for a new energy vehicle battery pack, including a first silicone foam 1 and a second silicone foam 2. A reinforcing plate 3 is fixedly disposed between the first silicone foam 1 and the second silicone foam 2. A first locking block 11 is fixedly installed on the right side of the first silicone foam 1. A first locking groove 31 is opened on the left side of the reinforcing plate 3. The first locking block 11 and the first locking groove 31 are movably engaged. The left side of the second silicone foam 2 is fixedly disposed on... A second locking block 21 is fixedly installed. A second locking groove 32 is opened on the right side of the reinforcing plate 3. The second locking block 21 and the second locking groove 32 are movably engaged. A limit groove 33 is opened through the front side of the reinforcing plate 3. The limit groove 33 is movably engaged with the limit block 34. A venting main hole 35 is opened on the top of the reinforcing plate 3. A venting secondary hole 36 is opened through the left side of the reinforcing plate 3. The venting main hole 35 and the venting secondary hole 36 are connected. The venting main hole 35 is connected to the limit groove 33.
[0018] In this implementation scheme, with the cooperation of the reinforcing plate 3 and the limiting block 34, the buffering performance between the two battery modules is ensured, while the overall support and heat dissipation performance of the buffer pad is also improved. When the new energy vehicle is driving at high speed or braking suddenly, the battery module is not easy to move because the buffer pad has sufficient support while maintaining the buffering performance.
[0019] Specifically, a fixed card slot is provided in the middle of the front side of the first card block 11 and the second card block 21, and the limiting card block 34 is movably engaged with the fixed card slot.
[0020] In this embodiment, the first silicone foam 1 and the second silicone foam 2 are limited by the limiting block 34.
[0021] Specifically, there are multiple reinforcing plates 3, and the thickness of each reinforcing plate 3 is different.
[0022] In this embodiment, while ensuring the buffering performance between the two battery modules, a reinforcement plate 3 of appropriate thickness can be selected, and the assembly between the reinforcement plate 3, the first silicone foam 1, and the second silicone foam 2 can be completed quickly.
[0023] Specifically, the outer top of both the first locking slot 31 and the second locking slot 32 has a rounded corner design.
[0024] In this embodiment, the first card block 11 and the second card block 21 are thus made easier to engage into the first locking slot 31 and the second locking slot 32, respectively.
[0025] Specifically, the first card block 11 and the second card block 21 are misaligned.
[0026] In this embodiment, the layout of both sides of the reinforcing plate 3 has been optimized.
[0027] In use, once the distance between the two battery modules is determined, the required thickness of the first silicone foam 1 and the second silicone foam 2 is calculated. While ensuring the buffering performance between the two battery modules, a reinforcement plate 3 of appropriate thickness is selected. The first silicone foam 1 is fixed to the left side of the reinforcement plate 3 by engaging the first locking block 11 and the first locking slot 31, with the fixing slot on the first locking block 11 aligned with the limiting slot 33. Then, the second silicone foam 2 is fixed to the right side of the reinforcement plate 3 by engaging the second locking block 21 and the second locking slot 32, with the fixing slot on the second locking block 21 aligned with the limiting slot 33. The locking block 34 is inserted into the limiting slot 33. The locking block 34 engages with the limiting slot 33 and the fixing slot to limit the first silicone foam 1 and the second silicone foam 2. The cooperation of the ventilation holes 36 and the main ventilation holes 35 increases the heat dissipation performance between the first silicone foam 1 and the second silicone foam 2. When the new energy vehicle is driving at high speed or braking suddenly, the buffer pad has sufficient support while maintaining the buffer performance, making it difficult for the battery module to shift. This stability can ensure that the electrical connectors inside the module are subjected to uniform force, avoiding loosening or breakage, thereby effectively preventing safety hazards such as short circuits, overheating or even fires.
[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
