Description

Technical Field

[0001] The utility model belongs to the technical field of thermal insulation pads, in particular to an aerogel thermal insulation pad with support angles. Background Art

[0002] Aerogel insulation pads are a new type of material with excellent thermal insulation properties. Aerogel itself is a solid material with a nanoporous structure. Its porosity is extremely high and it is filled with a large amount of air, which greatly reduces heat conduction. When aerogel is made into an insulation pad, it can effectively prevent heat transfer.

[0003] At the same time, the patent application number 202223377735.5 discloses an aerogel insulation pad with support angles, which includes an outer shell, an aerogel piece and a packaging film; a receiving groove is provided on the outer shell, and at least one support angle is protruding from the side of the outer shell, and a deformation space is formed between two adjacent support angles; the aerogel piece is arranged in the receiving groove; the packaging film is attached to the outer shell and covers the opening of the receiving groove.

[0004] However, in the implementation of relevant technologies, it was found that the side of the aerogel insulation pad with support angles mentioned above is in contact with the battery cell. When the aerogel of the insulation pad expands due to heat, the elastic silicone shell also expands and squeezes the battery cell, causing the battery cell shell to deform and then rupture, thereby reducing the service life of the aerogel insulation pad. Utility Model Content

[0005] To address the issues raised in the aforementioned background technology, the present invention provides an aerogel thermal insulation mat with support angles. This mat is lightweight and thin, thus minimizing the burden on users. Compared to traditional insulation materials, it maintains excellent insulation performance while taking up less space. This also prevents the mat from squeezing the battery cell, potentially causing deformation or rupture.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an aerogel insulation pad with support angles, comprising a top packaging film, an outer shell and an aerogel piece, a notch being provided inside the outer shell, a support angle body being provided on the outer side of the outer shell, a buffer area being provided between two groups of the support angle bodies, the aerogel piece being provided inside the notch, and the bottom end of the top packaging film being provided at the top end of the notch.

[0007] Preferably, the aerogel piece is configured as a nanoporous SiO2 aerogel.

[0008] Preferably, the top end of the top packaging film is fixedly connected with a first glue, the top end of the first glue is fixedly connected with a first heat insulation layer, and the first heat insulation layer is set to be a PET material.

[0009] Preferably, a bottom packaging film is attached to the bottom end of the notch, a second glue is fixedly connected to the bottom end of the bottom packaging film, and a second heat insulation layer is fixedly connected to the bottom end of the second glue.

[0010] Preferably, the bottom packaging film is made of PET material.

[0011] Preferably, the material of the first thermal insulation layer and the second thermal insulation layer is nano-silica aerogel.

[0012] Preferably, the shell is made of silicone material, and at least one supporting angle body is protruding from the front side, rear side, left side and right side of the shell.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The utility model utilizes aerogel, a solid material with a nanoporous structure. Its porosity is extremely high and the interior is filled with a large amount of air, which greatly reduces heat conduction. The aerogel insulation pad is light and thin, and does not bring excessive burden to the user. Compared with traditional insulation materials, it takes up less space while maintaining thermal insulation performance. The design of the two support angles arranged at intervals not only creates deformation space, but also reduces the contact area between the battery cell and the insulation pad, making it more difficult for the battery cell to deform.

[0015] 2. In the present invention, when the aerogel component is heated and expanded, the outer shell also expands accordingly, and the buffer area provides sufficient expansion gap for the outer shell. The aerogel insulation pad has extremely low thermal conductivity, good flexibility and fire resistance. With the action of the aerogel core layer arranged at the bottom of the insulation layer, the aerogel insulation pad has high temperature resistance, thereby achieving heat insulation during use and extending the service life of the aerogel component.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 5 As shown, the utility model provides an aerogel insulation pad with support angles, including a top packaging film 1, an outer shell 4 and an aerogel piece 7. When the aerogel piece 7 expands due to heat, the outer shell 4 also expands accordingly, and the buffer area 6 provides sufficient expansion gap for the outer shell 4. A notch 11 is opened inside the outer shell 4, and a support angle body 5 is provided on the outside of the outer shell 4. A buffer area 6 is provided between two groups of support angle bodies 5. The aerogel piece 7 is arranged inside the notch 11, and the bottom end of the top packaging film 1 is arranged at the top of the notch 11 and is fitted therewith.

[0024] Specifically, the aerogel piece 7 is configured as a nanoporous SiO2 aerogel. Due to its extremely high porosity, the interior is filled with a large amount of air, thereby greatly reducing heat conduction.

[0025] Furthermore, the top of the top packaging film 1 is fixedly connected to the first glue 2, the top of the first glue 2 is fixedly connected to the first heat insulation layer 3, and the first heat insulation layer 3 is set to be a PET material.

[0026] Furthermore, the bottom end of the notch 11 is adhered with a bottom packaging film 10 , the bottom end of the bottom packaging film 10 is fixedly connected with a second glue 9 , and the bottom end of the second glue 9 is fixedly connected with a second heat insulation layer 8 .

[0027] It is worth noting that the bottom packaging film 10 is made of PET material, and the second glue 9 is made of high-temperature resistant material, which is not easy to age and deform under long-term use.

[0028] It is worth noting that the material of the first thermal insulation layer 3 and the second thermal insulation layer 8 is nano-silicon dioxide aerogel, which occupies less space while ensuring thermal insulation performance.

[0029] It is worth mentioning that the shell 4 is made of silicone material, and at least one supporting angle body 5 is protruding from the front side, rear side, left side and right side of the shell 4, which takes up less space, and there are two supporting angle bodies 5 arranged at intervals. The design of the two supporting angle bodies 5 not only forms a deformation space, but also reduces the contact area between the battery cell and the second insulation layer 8, making it more difficult for the battery cell to deform.

[0030] Among them, the top packaging film 1, the shell 4 and the aerogel piece 7 are existing technologies and will not be described in detail; at the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail.

[0031] Working principle:

[0032] During use, a notch 11 is opened inside the shell 4, and the aerogel piece 7 is placed inside the notch 11. When the aerogel piece 7 expands due to heat, the shell 4 also expands accordingly, and the buffer area 6 provides sufficient expansion gap for the shell 4. A notch 11 is opened inside the shell 4, and a support angle body 5 is provided on the outside of the shell 4. A buffer area 6 is provided between the two groups of support angle bodies 5. The aerogel piece 7 is arranged inside the notch 11, and the bottom end of the top packaging film 1 is arranged at the top of the notch 11 and is bonded thereto. The aerogel piece 7 is set to a nanoporous structure SiO2 aerogel, and SiO2 aerogel is a high-temperature resistant aerogel that is widely studied and relatively mature in the field of thermal insulation. Because of its extremely high porosity, it is filled with a large amount of air inside, which greatly reduces heat conduction. The top of the top packaging film 1 is fixedly connected to the first glue 2, and the top of the first glue 2 is fixedly connected to the first thermal insulation layer 3 for thermal insulation. The bottom packaging film 10 is set to PET material, and the second glue 9 is set to high-temperature resistant material. Under long-term use, it is not easy to age and deform. The material of the first thermal insulation layer 3 and the second thermal insulation layer 8 is nano-silica aerogel, and the nano-silica aerogel has extremely low thermal conductivity, good flexibility and fire resistance. While ensuring thermal insulation performance, it occupies less space. The front side, rear side, left side and right side of the shell 4 are all convexly provided with at least one supporting angle body 5, which occupies less space, and there are two supporting angle bodies 5 arranged at intervals. The design of the two supporting angle bodies 5 not only forms a deformation space, but also reduces the contact area between the battery cell and the second thermal insulation layer 8, making it more difficult for the battery cell to deform.
