Description

Technical Field

[0001] This utility model belongs to the technical field of power battery heat insulation pads, specifically relating to an aerogel heat insulation pad with a sandwich structure. Background Technology

[0002] With the continuous increase in sales of new energy vehicles, incidents of battery pack spontaneous combustion and collision-induced fires are becoming increasingly common. Global users are no longer primarily concerned about driving range, but rather the safety of the power batteries. Currently used pure aerogel encapsulation products cannot meet the mechanical performance requirements of battery packs, such as compression, and are also unsuitable for the needs of various irregularly shaped batteries. Utility Model Content

[0003] This invention provides an aerogel thermal insulation pad with a sandwich structure to solve the technical problem of simultaneously meeting the thermal insulation and mechanical requirements of battery packs.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An aerogel thermal insulation pad with a sandwich structure includes an aerogel thermal insulation core, an encapsulation layer, and an elastomer. The aerogel thermal insulation core is encapsulated by the encapsulation layer to obtain an encapsulated core. An elastomer is adhered to at least one working end face of the encapsulated core. This invention adds an elastomer to the encapsulated aerogel core, giving it a sandwich structure. The shape can be changed as needed, with a square shape being the most common. The encapsulated core does not shed powder, and the elastomer adhered to the outside of the encapsulation layer allows for better fixation of the thermal insulation pad to the battery cells and better mechanical deformation.

[0006] As a preferred embodiment of this utility model, the aerogel insulation core material is a folded core material.

[0007] As a preferred embodiment of this utility model, an elastomer is attached to the two working end faces of the encapsulation core material.

[0008] In a preferred embodiment of this utility model, the encapsulation layer is an encapsulation film.

[0009] As a preferred embodiment of this utility model, the encapsulation film is a PET film or a PI film.

[0010] In a preferred embodiment of this utility model, the elastic body is a U-shaped frame.

[0011] As a preferred embodiment of this utility model, the spiral frame is any one of a rubber spiral frame, a PC spiral frame, or a foam spiral frame.

[0012] As a preferred embodiment of this utility model, the elastic body can also be an elastic strip, which is attached to the working end face of the encapsulation core material at intervals or in a spliced ​​manner.

[0013] This utility model uses an encapsulation core material as the inner core, and an elastomer is separately glued to the outside of the inner core to meet the heat insulation pad requirements of different types of battery packs. The encapsulation core material can be mass-produced, and the elastomer can be glued to the outside of different types of battery packs, thus improving the applicability of this utility model.

[0018] Example:

[0019] A sandwich-structured aerogel insulation pad, such as Figure 1 and 2 As shown, it includes an aerogel insulation core material, an encapsulation layer, and an elastomer 2. The aerogel insulation core material is encapsulated by the encapsulation layer to obtain an encapsulated core material 1. The aerogel insulation core material can be aerogel insulation materials such as ceramic aerogel, pre-oxidized fiber aerogel, and glass fiber aerogel. The encapsulation layer is encapsulated using an encapsulation film, such as PET film or PI film. The encapsulation method can be edgeless encapsulation, four-sided encapsulation, etc. The aerogel insulation core material is a folded core material, which can be folded by wrapping or stacked vertically. After folding, it is encapsulated by the encapsulation layer to form an encapsulated core material.

[0020] Then, elastomers 2 are attached to the two working ends of the encapsulated core material. In this embodiment, the elastomers used are U-shaped frames, which can be rubber U-shaped frames, PC U-shaped frames, or foam U-shaped frames. Of course, the thickness and width of the elastomers are made according to the heat insulation pad requirements of different battery packs. Elastic strips can also be used for intermittent pasting or assembled into a frame shape, as long as it can achieve elastic protection for the core material.

[0021] This invention adds an elastomer to the encapsulated aerogel core material, giving it a sandwich structure. The shape can be changed as needed, with a square shape being the most common. The encapsulated core material does not shed powder, and the elastomer is attached to the outside of the encapsulation layer, allowing for better adjustment of the elastomer's shape according to the type of battery pack.
