Description

Technical Field

[0001] The utility model belongs to the technical field of thermal insulation pads, and in particular relates to a thermal insulation pad using a breakpoint film material packaging structure. Background Art

[0002] In order to ensure the safety of passengers, new energy power battery packs usually use flame-retardant insulation materials between battery cells to delay or block the transfer of heat and flames during thermal runaway, buy time for passengers to escape, and reduce property losses. In addition, during the charging and discharging process, the volume of new energy power battery cells will repeatedly expand and contract, and if the battery cells are squeezed during expansion, it will affect the cycle life of the battery cells, so the insulation pads also need to have a certain buffering capacity.

[0003] In the current production process of thermal insulation pads, large pieces of thermal insulation core material need to be cut into small pieces and then packaged individually, which is inefficient. Utility Model Content

[0004] The utility model provides a thermal insulation pad using a breakpoint film packaging structure, using a packaging film material with an easy-tear line to package an insulating core material, multiple thermal insulation pads can be processed at one time, and the desired number of thermal insulation pads can be obtained by simply removing them along the easy-tear line, eliminating the cutting process, reducing production costs and improving efficiency.

[0005] The technical solution adopted by the utility model is:

[0006] A thermal insulation pad using a breakpoint film material packaging structure includes a breakpoint packaging film material and a thermal insulation core material, wherein the breakpoint packaging film material packages the thermal insulation core material, and the breakpoint packaging film material includes at least two sub-packaging films, and an easy-tear line is provided between adjacent sub-packaging films. The sub-packaging films can be separated by the easy-tear line as needed.

[0007] As a preferred solution of the utility model, the corners of the sub-packaging film are chamfered, and the distance between the two chamfers in the length direction of the sub-packaging film is equal to the length of the thermal insulation core material. The chamfer is easy to tear when pulling, without damaging the main body.

[0008] As a preferred solution of the present invention, the thermal insulation core material is an aerogel thermal insulation core material.

[0009] As a preferred solution of the utility model, a heat insulating core material is placed on each sub-packaging film, and each sub-packaging film wraps and packages its own heat insulating core material. Each sub-packaging film can wrap itself to package the heat insulating core material, and multiple packaged heat insulating pads can be produced at one time.

[0010] As a preferred solution of the utility model, two adjacent sub-packaging films package one heat insulating core material. The heat insulating core materials are placed one by one, and the adjacent sub-packaging film without heat insulating core material is covered on the sub-packaging film with heat insulating core material for edge sealing around the perimeter.

[0011] As a preferred solution of the utility model, the spacing between the two chamfers in the width direction of the sub-packaging film is equal to the width of the thermal insulation core material. For the thermal insulation pad with sealed edges all around, the four corners of the sub-packaging film are chamfered, and the uniform specifications facilitate production.

[0012] The utility model adopts breakpoint packaging film materials to package aerogel insulation core materials in different structures (winding, four-edge sealing, etc.), which is convenient for placing the core material in a central position and multiple pieces can be packaged at the same time, and the operability is strong; after the packaging is completed, a single piece of insulation pad can be directly separated from the breakpoint, and multiple pieces can be linked according to needs, eliminating the cutting process, reducing production costs and improving efficiency.
