During battery charging and discharging, they can effectively control battery temperature, prevent thermal runaway, and improve battery safety and performance. They are also used for thermal insulation in electronic devices.

[0003] Currently, thin aerogel insulation sheets use a buffer layer between the reinforcing layer and the aerogel core layer to buffer external impacts and pressures, reducing damage to the aerogel caused by vibration and collisions. It also provides some buffer space for the aerogel to expand and contract with temperature. However, the buffer layer is located inside the aerogel insulation sheet, so the buffering effect is not good. Utility Model Content

[0006] According to the aforementioned thin aerogel insulation sheet, there are multiple buffer pads, wedge-shaped buffer strips, circular protrusions, and semi-cylindrical buffer strips. The surfaces of the buffer pads, wedge-shaped buffer strips, circular protrusions, and semi-cylindrical buffer strips are all provided with a high-temperature resistant coating, which extends the service life of the buffer pads, wedge-shaped buffer strips, circular protrusions, and semi-cylindrical buffer strips.

[0007] According to the aforementioned thin aerogel insulation sheet, a reinforcing layer is provided on the upper surface of the second buffer layer, and an encapsulation protective layer is provided on the upper surface of the reinforcing layer, the encapsulation protective layer providing protection for the insulation sheet.

[0008] According to the aforementioned thin aerogel insulation sheet, a protective layer is provided on the lower surface of the reinforcing layer, and the protective layer provides protection for the insulation sheet.

[0009] According to the aforementioned thin aerogel insulation sheet, the side surface of the aerogel insulation layer is bonded to the protective layer, and the side surface of the second buffer layer is bonded to the protective layer.

[0010] According to the aforementioned thin aerogel insulation sheet, the side surface of the surface layer is bonded to the protective layer, and the side surface of the heat dissipation plate is bonded to the protective layer.

[0011] According to the aforementioned thin aerogel insulation sheet, the thickness of the aerogel insulation layer is 1.0-5.0 mm.

[0012] The above-mentioned solution has the following beneficial effects:

[0013] By incorporating an aerogel insulation layer, a first buffer layer, a surface layer, a second buffer layer, a heat dissipation plate, a heat dissipation groove, a buffer pad, wedge-shaped buffer strips, circular protrusions, and semi-cylindrical buffer strips, the impact force generated by external vibrations can be buffered, reducing the damage to the aerogel insulation layer and internal structure caused by vibrations and collisions. At the same time, it provides buffer space for the internal aerogel to expand and contract with temperature, improving the impact resistance and durability of the insulation sheet. Furthermore, the buffer pad, wedge-shaped buffer strips, circular protrusions, and semi-cylindrical buffer strips can raise the usable height of the heat dissipation plate and heat dissipation groove, helping to quickly dissipate the heat absorbed by the insulation sheet, resulting in good heat dissipation effect.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 This utility model discloses a thin aerogel heat insulation sheet, comprising: an aerogel heat insulation layer 1 with a thickness of 1.0-5.0 mm; a first buffer layer 2 on the lower surface of the aerogel heat insulation layer 1; and a second buffer layer 10 on the upper surface of the aerogel heat insulation layer 1. The first buffer layer 2 and the second buffer layer 10 provide a certain buffer space for the aerogel during thermal expansion and contraction. A surface layer 3 is provided on the lower surface of the first buffer layer 2, and a heat dissipation plate 4 is provided on the lower surface of the surface layer 3. A heat dissipation groove 5 is provided inside the heat dissipation plate 4, allowing the heat dissipation plate 4 and the heat dissipation groove 5 to dissipate heat in a timely manner. A buffer pad 6 is fixedly connected to the lower surface of the heat dissipation plate 4, and a wedge-shaped buffer strip 7 is fixedly connected to the lower surface of the buffer pad 6. Circular protrusions 8 and semi-cylindrical buffer strips 9 are fixedly connected to the lower surface of the buffer pad 6. When the heat insulation sheet is subjected to external shaking or impact during use, the wedge-shaped buffer strip 9... The wedge-shaped buffer strip 7, circular protrusions 8, and semi-cylindrical buffer strip 9 undergo compression deformation, converting impact energy into their own elastic potential energy, thereby slowing down the transmission of impact force. The buffer pad 6 further buffers the impact force, reducing the impact force acting directly on the surface of the aerogel insulation sheet, reducing the damage to the aerogel insulation layer 1 and its internal structure caused by vibration and collision. At the same time, it works together with the first buffer layer 2 and the second buffer layer 10 to provide buffer space for the internal aerogel when it expands and contracts with temperature. There are multiple buffer pads 6, wedge-shaped buffer strips 7, circular protrusions 8, and semi-cylindrical buffer strips 9. Multiple buffer pads 6, wedge-shaped buffer strips 7, circular protrusions 8, and semi-cylindrical buffer strips 9 provide good buffering effect. The surfaces of the buffer pads 6, wedge-shaped buffer strips 7, circular protrusions 8, and semi-cylindrical buffer strips 9 are all coated with high-temperature resistant coatings, which extends the service life of the buffer pads 6, wedge-shaped buffer strips 7, circular protrusions 8, and semi-cylindrical buffer strips 9.

[0024] The upper surface of the second buffer layer 10 is provided with a reinforcing layer 11, the upper surface of the reinforcing layer 11 is provided with an encapsulation and protective layer 12, the lower surface of the reinforcing layer 11 is provided with a protective layer 13, the side surface of the aerogel heat insulation layer 1 is adhered to the protective layer 13, the side surface of the second buffer layer 10 is adhered to the protective layer 13, the side surface of the surface layer 3 is adhered to the protective layer 13, and the side surface of the heat dissipation plate 4 is adhered to the protective layer 13. The encapsulation and protective layer 12 and the protective layer 13 provide protection for the heat insulation sheet.

[0025] Working principle: When the heat insulation sheet is subjected to external shaking and impact during use, the wedge-shaped buffer strip 7, the circular protrusion 8, and the semi-cylindrical buffer strip 9 will undergo compression deformation, converting the impact energy into their own elastic potential energy, thereby slowing down the transmission of impact force. The buffer pad 6 further buffers the impact force, reducing the impact force acting directly on the surface of the aerogel heat insulation sheet, reducing the damage to the aerogel heat insulation layer 1 and internal structure caused by vibration and collision. At the same time, together with the first buffer layer 2 and the second buffer layer 10, they work to provide buffer space for the internal aerogel when it expands and contracts with heat. In addition, during use, the buffer pad 6, wedge-shaped buffer strip 7, circular protrusion 8, and semi-cylindrical buffer strip 9 raise the working height of the heat dissipation plate 4, thereby increasing the heat dissipation space between the heat dissipation grooves 5 and improving the heat dissipation efficiency.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
