Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulating buffer pads, and more specifically to a heat-insulating buffer pad. Background Art

[0002] The thermal insulation cushion is a material with thermal insulation and cushioning functions. It is usually composed of a thermal insulation layer and a buffer layer. It is mainly used to protect battery cells and other equipment from thermal damage and mechanical shock. The application of thermal insulation cushions in new energy vehicle batteries is mainly to prevent the mechanical stress caused by expansion and contraction of the battery during charging and discharging, and in extreme cases such as thermal runaway, to prevent heat from diffusing to surrounding battery cells, thereby protecting the safety and stability of the battery pack. At present, when the thermal insulation cushion is used for a long time, there is usually no protective measure on the outside, which makes it inconvenient to protect the thermal insulation buffer layer, which can easily affect the service life of the thermal insulation cushion, which needs to be improved.

[0016] Next, the technical solutions in the utility model will be clearly and completely described in conjunction with the drawings in the utility model. In addition, the forms of each structure recorded in the following embodiments are only examples, and a heat insulation and buffer pad related to the utility model is not limited to the structures recorded in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the utility model.

[0017] Embodiment 1:

[0018] As Figures 1-3 shown, a heat insulation and buffer pad includes a heat insulation and buffer layer 1. A protective fabric layer 4 is provided outside the heat insulation and buffer layer 1. The protective fabric layer 4 wraps around the outside of the heat insulation and buffer layer 1. The protective fabric layer 4 includes nylon fibers 5 and aramid fibers 6, and the protective fabric layer 4 is woven by interlacing nylon fibers 5 and aramid fibers 6.

[0019] In this embodiment, both the polyamide fiber 5 and the aramid fiber 6 have good wear resistance, high temperature resistance, corrosion resistance, and can withstand large external forces without being easily deformed or broken. The protective fabric layer 4 formed by cross-weaving the polyamide fiber 5 and the aramid fiber 6 facilitates the protection of the heat insulation and buffer layer 1.

[0020] Embodiment Two:

[0021] As Figures 1-3 shown, the heat insulation and buffer layer 1 includes an aerogel heat insulation layer 2 and a polyurethane foam buffer layer 3. A metal fiber mesh 21 is embedded inside the aerogel heat insulation layer 2. The metal fiber mesh 21 is formed by cross-weaving multiple copper wires. The thickness of the aerogel heat insulation layer 2 is 15 mm to 20 mm. The number of the polyurethane foam buffer layers 3 is two. The two polyurethane foam buffer layers 3 are adhesively bonded to both sides of the aerogel heat insulation layer 2 through hot melt adhesive. The thickness of both of the two polyurethane foam buffer layers 3 is 8 mm to 10 mm.

[0022] In this embodiment, the material of the polyurethane foam buffer layer 3 is polyurethane foam. The polyurethane foam has excellent buffering performance and can absorb and disperse the impact force, facilitating buffer protection. The material of the aerogel heat insulation layer 2 is aerogel. The aerogel has the dual functions of heat insulation and electromagnetic shielding and can effectively isolate the heat generated by the battery pack and protect the surrounding components from the influence of high temperature. As an electromagnetic shielding material, the metal fiber mesh 21 has the function of shielding electromagnetic radiation. By embedding the metal fiber mesh 21 inside the aerogel heat insulation layer 2, the electromagnetic shielding ability of the aerogel heat insulation layer 2 can be effectively improved.

[0023] In summary, as Figures 1-3 shown, when protecting the battery of a new energy vehicle with this heat insulation and buffer pad, the heat insulation and buffer layer 1 is protected by the protective fabric layer 4, and the battery is protected by the excellent buffering and shock-absorbing performance of the polyurethane foam buffer layer 3. At the same time, the heat generated by the battery pack is isolated by the aerogel heat insulation layer 2 to protect the surrounding components from the influence of high temperature. Both the aerogel heat insulation layer 2 and the metal fiber mesh 21 have the function of electromagnetic shielding. By embedding the metal fiber mesh 21 inside the aerogel heat insulation layer 2, the electromagnetic shielding ability of the aerogel heat insulation layer 2 can be effectively improved, and the electromagnetic interference of the battery pack on the surrounding electronic devices can be reduced.
