Description

Technical Field

[0001] The utility model belongs to the technical field of power battery heat insulation pads, and in particular relates to a heat insulation pad whose core material is flush with a single side of a return frame. Background Art

[0002] With the continuous increase in sales of new energy vehicles, global users are gradually increasing their cost competitiveness for new energy vehicles while ensuring the driving range and power battery safety. At present, the conventionally used thermal insulation pads with return frames have both end faces of the core material recessed in the return frame. This is because during vacuum hot pressing and compounding, the two end faces of the core material are recessed in the return frame. Because there is a gap between the core material and the glue frame, after the entire surface is backed with glue, it will cause double-sided glue bubbles at the gap point. After the bubbles are heated, it will affect the thermal insulation bonding. In addition, the core material is recessed in the return frame. After backing with glue, only the double-sided glue on the surface of the glue frame starts the bonding effect, and the double-sided glue in the core material area fails and cannot contact the battery pack. Utility Model Content

[0003] In view of the problems mentioned in the prior art, the utility model provides a heat insulation pad whose core material is flush with one side of a return frame.

[0004] The technical solution adopted by the utility model is:

[0005] A heat insulation pad whose core material is flush with one side of a circular frame, comprising a circular frame, a heat insulation core material and a packaging film, wherein the heat insulation core material is arranged in the central placement hole of the circular frame, and one working end face of the heat insulation core material is flush with the end face of the circular frame, and the other working end face of the heat insulation core material is lower than the other end face of the circular frame, and the packaging film packages the combined heat insulation core material and circular frame. The structure that the single side is flush with one side of the circular frame not only satisfies the design of the thickness of the core material and the circular frame of the heat insulation pad with the heat insulation core material sunken into the circular frame, but also strengthens the effective contact area with the battery pack after the surface adhesive is flushed, thereby increasing the bonding force between the heat insulation pad and the battery pack.

[0006] As a preferred solution of the utility model, the return frame is any one of a rubber frame, a PC frame and a foam return frame.

[0007] As a preferred solution of the utility model, the thermal insulation core material is an aerogel thermal insulation core material.

[0008] As a preferred solution of the utility model, the thermal insulation core material is any one of ceramic aerogel, pre-oxidized silk aerogel and glass fiber aerogel.

[0009] As a preferred solution of the present invention, the packaging film is a PET film or a PI film, etc. The material of the packaging film is not limited to the types given above.

[0010] The thermal insulation pad of the utility model changes the structure of a conventional thermal insulation core material sunken in a return-form frame, so that one working end face of the thermal insulation core material is flush with one end face of the return-form frame. The structure of one side being flush with one side of the return-form frame not only meets the design of the thickness of the core material and the return-form frame of the thermal insulation pad thermal insulation core material sunken in the return-form frame structure, but also strengthens the effective contact area with the battery pack after the flat backing adhesive is flush, thereby increasing the adhesion between the thermal insulation pad and the battery pack.
