[0003] For example, Chinese patent CN217863141U discloses a lightweight fire-resistant and heat-insulating pad, which includes a glass fiber layer, a first silicone foam layer, an aerogel layer and a second silicone foam layer stacked in sequence.

[0004] Although the aforementioned patents have solved the problems of unsatisfactory heat insulation effect and heavy weight of the heat insulation pad by using glass fiber layer and aerogel layer, the heat insulation pad is directly glued and fixed during use, making it difficult to disassemble and reuse. When disassembling and maintaining the battery, the existing heat insulation pad can only be damaged, which easily leads to waste of resources. Utility Model Content

Therefore, this invention proposes an environmentally friendly, high-temperature resistant automotive heat insulation pad.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an environmentally friendly, high-temperature resistant automotive heat insulation pad, comprising a heat insulation pad body, a limiting plate overlapping one side of the heat insulation pad body, a limiting mechanism provided on one side of the limiting plate, the limiting mechanism comprising frame one, frame four and an extension frame, frame two slidably connected to one end of frame one, frame three slidably connected to one end of frame two, the inner wall of frame three slidably connected to frame four, and one end of frame four slidably connected to the inner wall of frame one, frame one, frame two, frame three and frame four forming a fixed frame, one side of the two extension frames being fixedly connected to frame two and frame three respectively, and an arc-shaped spring piece fixedly connected to the inner wall of the extension frame, one side of the arc-shaped spring piece overlapping the heat insulation pad body.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Refer to Figures 1-4 As shown: An environmentally friendly, high-temperature resistant automotive heat insulation pad includes a heat insulation pad body 3. A limiting plate 6 overlaps one side of the heat insulation pad body 3, and a limiting mechanism is provided on one side of the limiting plate 6. The limiting mechanism includes a first frame 1, a fourth frame 5, and an extension frame 7. A second frame 2 is slidably connected to one end of the first frame 1, and a third frame 4 is slidably connected to one end of the second frame 2. The inner wall of the third frame 4 is slidably connected to the fourth frame 5, and one end of the fourth frame 5 is slidably connected to the inner wall of the first frame 1. The first frame 1, the second frame 2, the third frame 4, and the fourth frame 5 are assembled. The frame is fixed, and one side of the two extension frames 7 is fixedly connected to the second frame 2 and the third frame 4 respectively. The inner wall of the extension frame 7 is fixedly connected to the arc-shaped spring piece 701. One side of the arc-shaped spring piece 701 overlaps with the heat insulation pad body 3. The limiting plate 6 is connected to the first frame 1 and the fourth frame 5 by bolts. The fourth frame 5 and the third frame 4 are connected by a pin. The fourth frame 5 and the first frame 1 are also connected by a pin. One side of the first frame 1 and the fourth frame 5 is fixedly connected to the insertion strip 9. One end of the insertion strip 9 is inserted into the heat insulation pad body 3.

[0024] The length of the fixing frame can be adjusted by sliding between frames 1, 2 and 4, and frames 5. The width of the fixing frame can also be adjusted by sliding between frames 1, 4 and 5, and frames 2 and 4, thus adapting to batteries and heat insulation pad bodies 3 of different sizes. The extension frame 7 and the arc-shaped spring 701 can guide the installation of the heat insulation pad body 3. The heat insulation pad body 3 moves along the inner wall of the extension frame 7 towards the side close to the insertion strip 9, so that one side of the heat insulation pad body 3 is inserted into the insertion strip 9, realizing the initial installation of the heat insulation pad body 3. By rotating the bolts, the upper and lower symmetrical limiting plates 6 apply pressure to the heat insulation pad body 3, which can fix the heat insulation pad body 3, thereby reducing the loosening of the heat insulation pad body 3 during use.

[0025] Example 2: Figures 1-4 As shown, mounting blocks 8 are snapped onto one side of frames 1, 2, 4, and 5. Bolts are inserted through the mounting blocks 8. The heat insulation pad body 3 includes a surface protective layer 301, a main heat insulation layer 303, and a substrate bottom layer 305. A high-temperature resistant reflective layer 302 is laminated on one side of the surface protective layer 301. The thickness of the surface protective layer 301 is half that of the high-temperature resistant reflective layer 302. The high-temperature resistant reflective layer 302 is laminated with the main heat insulation layer 303 on one side. The thickness of the high-temperature resistant reflective layer 302 is the same as that of the main heat insulation layer 303. A flame-retardant buffer layer 304 is laminated on one side of the main heat insulation layer 303. The flame-retardant buffer layer 304 is laminated with the substrate bottom layer 305 on one side.

[0026] The mounting block 8 and bolts can be used to assist in the installation of the entire device on the battery side. The surface protective layer 301 can wrap and protect the top of the high temperature resistant reflective layer 302. The high temperature resistant reflective layer 302 can be used to connect the surface protective layer 301 and the main heat insulation layer 303. The flame retardant buffer layer 304 can assist in the connection between the main heat insulation layer 303 and the substrate bottom layer 305. The substrate bottom layer 305 can be used to support and reinforce the bottom of the flame retardant buffer layer 304. Through the composite of multiple layers, the functionality of the heat insulation pad body 3 can be guaranteed during use.

[0027] The usage and working principle of this device are as follows: First, adjust the length and width of the fixing frame according to the size of the battery. After adjustment, install pins to fix the device between frame 1 and frame 2, frame 2 and frame 3, frame 3 and frame 4, and frame 1 and frame 4. Then, insert one end of the heat insulation pad body 3 into the extension frame 7. The arc-shaped spring 701 drives the heat insulation pad body 3 to move away from the extension frame 7, so that the other side of the heat insulation pad body 3 is in contact with frame 1 and frame 4. Then, rotate the bolts on the limiting plate 6 so that the upper and lower symmetrical limiting plates 6 are in contact with the surface protective layer 301 and the substrate bottom layer 305, respectively, to limit the heat insulation pad body 3. Install the heat insulation pad body 3 on one side of the battery. The mounting block 8 engages with the side wall of the battery. Rotate the bolts on the mounting block 8. Under the action of the threads, the end of the bolt abuts against the side wall of the battery. The overall installation of the heat insulation pad consists of a surface protective layer 301 made of basalt fiber cloth with an environmentally friendly silicone coating. The silicone coating forms an inert surface, preventing fiber scattering and environmental pollution, while also improving fire resistance. The high-temperature reflective layer 302 is made of vacuum-aluminized fiberglass cloth, which uses the principle of heat reflection to block high-temperature radiation, such as the radiant heat during thermal runaway of a battery pack, reducing heat transfer to the inner layer. The main heat insulation layer 303 is made of ceramic fiber aerogel composite material, which uses the ultra-low thermal conductivity of aerogel to block conductive heat, and the ceramic fiber enhances the structural strength, allowing it to withstand high compressive loads. The flame-retardant buffer layer 304 is made of intumescent flame-retardant polyurethane foam, which expands to form a carbonized layer when exposed to high temperatures, blocking heat penetration and buffering mechanical vibration and absorbing low-frequency noise. The bottom substrate 305 has a hot melt adhesive film on its surface, achieving hot-pressing bonding between the flame-retardant buffer layer 304 and the substrate.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
