After the heat preservation piece is mounted in the mounting space 11, the heat preservation cover 10 can effectively reduce the heat exchange between the heat preservation piece and the external environment, thereby reducing the heat loss, so as to keep the temperature of the heat preservation piece constant.

Moreover, the shape and size of the installation groove 21 can be adjusted to adapt to the heat preservation requirements of to-be-preserved parts of different shapes and sizes, improving the flexibility and applicability of the heat preservation cover 10.

[0036] According to some embodiments of the utility model, as shown in Figure 1 The first heat preservation cover 20 can include a heat preservation cover end cover 22 and a heat preservation cover side cover 23, the heat preservation cover end cover 22 and the heat preservation cover side cover 23 are integrally formed, the heat preservation cover end cover 22 is opposite to the second heat preservation cover 30 and spaced apart, and the heat preservation cover side cover 23 is arranged around the heat preservation cover end cover 22 along the peripheral edge of the heat preservation cover end cover 22 to define the installation groove 21.

[0038] The end cover 22 of the heat preservation cover is opposite and spaced apart from the second heat preservation cover 30, and the side cover 23 of the heat preservation cover is arranged around the circumferential edge of the end cover 22 of the heat preservation cover to define the mounting groove 21, so that the second heat preservation cover 30 cooperates with the first heat preservation cover 20 to define the mounting space 11, forming a relatively closed space, reducing the path of heat transfer to the outside through air convection and radiation, thereby further improving the heat preservation performance. And the first heat preservation cover 20 and the second heat preservation cover 30 are designed separately, which can facilitate independent disassembly and maintenance of the first heat preservation cover 20 and the second heat preservation cover 30, can reduce the maintenance cost of the heat preservation cover 10, and can facilitate installation and disassembly of the heat preservation cover 10.

[0039] According to some embodiments of the present application, as shown in Figure 1 The side cover 23 of the heat preservation cover can include a plurality of sub-side covers 231, for example, two, three, four or the like, but the present application is not limited thereto, and there can be other numbers of sub-side covers 231. The present application takes four sub-side covers 231 as an example for description. The plurality of sub-side covers 231 are arranged around the circumferential edge of the end cover 22 of the heat preservation cover, and any two adjacent sub-side covers 231 are adhered to each other, so that the plurality of sub-side covers 231 cooperates with the end cover 22 of the heat preservation cover to define the mounting groove 21, which can enhance the strength of the first heat preservation cover 20, help to resist the pressure and impact of the external environment, and ensure the stability and durability of the heat preservation device 100.

[0040] It can be explained that the number and shape of the sub-side cover 231 can be changed to adapt to different sizes and shapes of the to-be-heat-preserved member, thereby improving the versatility of the heat preservation device 100.

[0041] According to some embodiments of the present application, as shown in

[0042] It can be explained that the number and shape of the sub-side cover 231 can be changed to adapt to different sizes and shapes of the to-be-heat-preserved member, thereby improving the versatility of the heat preservation device 100. Figure 1As shown, the heat preservation device 100 can further comprise a second fixing structure 13, and any two adjacent sub-lateral covers 231 are fixedly connected through the second fixing structure 13 to limit the relative position between the two adjacent sub-lateral covers 231.

[0043] The second fixing structure 13 can be configured as a magic tape. The magic tape can be connected and detached very conveniently through the special Velcro design, without the need of additional tools or complex operations. The second fixing structure 13 can comprise a plurality of second sub-fixing structures 131, and any two adjacent sub-lateral covers 231 can be connected through the plurality of second sub-fixing structures 131 to limit the relative position between the two adjacent sub-lateral covers 231.

[0044] According to some embodiments of the present application, as shown in Figure 1 The first heat preservation cover 20 and the second heat preservation cover 30 can be attached to each other to reduce the gap therebetween and reduce heat loss. The attachment design can form a more airtight heat preservation environment for the heat preservation cover 10, thereby significantly improving the heat preservation performance of the heat preservation cover 10. The attachment of the first heat preservation cover 20 and the second heat preservation cover 30 allows the first heat preservation cover 20 and the second heat preservation cover 30 to support each other and form a more solid structure, thereby enhancing the structural stability of the entire heat preservation device 100.

[0045] Further, the first heat preservation cover 20 and the second heat preservation cover 30 can be connected through a plurality of first sub-fixing structures 121 to ensure the relative position between the first heat preservation cover 20 and the second heat preservation cover 30 is stable and prevent deformation or misplacement due to external force, so that the first heat preservation cover 20 and the second heat preservation cover 30 form a relatively closed mounting space 11 for mounting the heat preservation object, thereby effectively improving the heat preservation effect of the heat preservation device 100.

[0046] According to some embodiments of the present application, as shown in Figure 2 The first heat preservation cover 20 can comprise a flame-retardant layer 24, a heat preservation layer 25 and a corrosion-resistant layer 26 which are stacked, and the heat preservation layer 25 is located between the flame-retardant layer 24 and the corrosion-resistant layer 26.

[0047] The fire-retardant layer 24 can be made of fiber cloth material, and the fire-retardant layer 24 can resist chemical reagents such as gasoline, diesel, electrolyte and ethanol, can protect the internal material of the first heat preservation cover 20 from being damaged by the surrounding harsh environment, and can ensure that the fire-retardant layer 24 does not burn through or break within 1 hour under the flame burning at 1200 DEG C, thereby further ensuring the safety of the vehicle battery thermal runaway.

[0048] The heat preservation layer 25 can be made of aerogel asbestos material, the aerogel asbestos material has a very low thermal conductivity, can effectively prevent heat transfer, thereby achieving high-efficiency heat preservation and insulation effect, and can effectively prevent the influence of cold air on the to-be-heat-preserved part in the installation space 11. The heat preservation layer 25 can resist low temperature below -40 DEG C and high temperature above 100 DEG C, and is not prone to separation, foaming, deformation and the like after being stored in such environment for a long time, and the heat preservation effect is not affected.

[0049] The corrosion-resistant layer 26 can be made of high-silicon oxygen cloth material, can resist the corrosion of most chemicals, including strong acid, strong alkali and the like, thereby ensuring that the heat preservation layer 25 in the first heat preservation cover 20 is not corroded, and the safety and reliability of the first heat preservation cover 20 are improved.

[0050] The fire-retardant layer 24, the heat preservation layer 25 and the corrosion-resistant layer 26 are stacked to form an integral structure, thereby enhancing the structural stability of the first heat preservation cover 20, and the first heat preservation cover 20 has good corrosion resistance, fire resistance and heat preservation effect, and can well heat preserve and protect the to-be-heat-preserved part.

[0051] According to some embodiments of the present application, as shown in Figure 2 The thickness of the first heat preservation cover 20 is D1, the thickness of the heat preservation layer 25 is D2, and the relationship 0.5D1≤D2≤0.7D1 is satisfied.

[0052] The thickness D2 of the heat preservation layer 25 can be 0.5D1, 0.55D1, 0.6D1, 0.7D1 or the like, but the present application is not limited thereto, and the thickness D2 of the heat preservation layer 25 can also be other values within the range of 0.5D1-0.7D1, as long as the relationship 0.5D1≤D2≤0.7D1 is satisfied. Thus, when the thickness of the heat preservation layer 25 occupies a large proportion of the thickness of the first heat preservation cover 20, the heat preservation cover 10 can more effectively block the internal heat loss, and the overall heat preservation and insulation performance is significantly improved.

[0053] As an example of the present application, the overall thickness dimension D1 of the first heat preservation cover 20 can be greater than or equal to 10 mm, and the thicker thickness can improve the thermal resistance of the first heat preservation cover 20 (thermal resistance is the resistance in the process of heat transfer, the greater the thermal resistance, the slower the heat transfer, and the better the heat preservation effect), thereby more effectively blocking the internal heat loss, thereby improving the overall heat preservation and insulation performance. And the thicker first heat preservation cover 20 can provide better impact resistance to prevent damage caused by external impact.

[0054] According to some embodiments of the present application, the second heat preservation cover 30 can be configured as a foam layer. The foam layer is a kind of efficient heat insulation material, and its dense pore structure can effectively form a multiple reflection and scattering heat insulation interface, increase the resistance of heat conduction, and reduce heat energy loss. When the second heat preservation cover 30 adopts the foam layer, the heat preservation performance of the heat preservation cover 10 can be significantly improved, heat transfer is reduced, and the temperature in the installation space 11 is stable. Moreover, the foam layer also has excellent wear resistance, corrosion resistance and shock resistance, so that the second heat preservation cover 30 can maintain stable performance during long-term use and is not easily damaged. In addition, the foam layer also has a certain self-repairing ability and can resist scratches and dents to a certain extent.

[0055] Further, as an example of the present application, the first fixing structure 12 can be a strap, the first fixing structure 12 can include a plurality of first sub-fixing structures 121, the second fixing structure 13 can be configured as a magic tape, the second fixing structure 13 can include a plurality of second sub-fixing structures 131, the object to be heat preserved can be a battery device, and the adapter can include a frame for mounting the battery device and a cross beam of a vehicle.

[0056] When the battery device is installed on the frame, the first heat preservation cover 20 is sleeved on the battery device from above the battery device, and the adjacent two sub-side covers 231 of the first heat preservation cover 20 can be connected by a plurality of second sub-fixing structures 131, so that the first heat preservation cover 20 is stably covered on the outer periphery of the battery device, and the first heat preservation cover 20 and the adapter can be connected by the first fixing structure 12, so that the first heat preservation cover 20 is more stably covered on the outer periphery of the battery device. The second heat preservation cover 30 can be directly pasted on the lower surface of the battery device, and the second heat preservation cover 30 covers the lower surface of the adapter and the battery device. The first heat preservation cover 20 and the second heat preservation cover 30 can be connected by a plurality of first sub-fixing structures 121, so that the first heat preservation cover 20 and the second heat preservation cover 30 seal the battery device in the heat preservation cover 10. Thus, the heat preservation cover 10 can be more firmly sleeved on the surface of the battery device, which helps to prevent the heat preservation cover 10 from being displaced or falling off under the influence of external force (such as wind force), thereby improving the heat preservation effect of the heat preservation device 100.
