Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of battery heat insulation, and in particular relates to a box-mounted auxiliary packaged aerogel heat insulation pad. Background Art
[0002] The key technologies of new energy vehicles lie in the three major systems of battery system, motor system and electronic control system. As the power source of the vehicle, the battery system will often cause immeasurable losses once safety problems such as thermal runaway occur. In order to solve the thermal runaway problem of the battery system, thermal insulation pads are widely set between battery cells / modules. On the one hand, they play a role of heat insulation, and on the other hand, they prevent adjacent battery modules from squeezing and rubbing against each other, thereby avoiding the occurrence of thermal runaway to a certain extent.
[0003] The frameless thermal insulation pad includes a thermal insulation core material, and upper and lower packaging films that encapsulate the thermal insulation core material. The finished packaging film is a multi-layer structure, including an organic film layer, an adhesive film layer and a release film layer laminated from top to bottom. When in use, the release film layer is peeled off, and the upper and lower end surfaces of the thermal insulation core material are laminated and covered, and then vacuum hot pressing is performed using a vacuum hot press machine to complete the production of the frameless thermal insulation pad.
[0004] However, the packaging film used in existing thermal insulation pads has insufficient viscosity, and it is difficult to control the thickness of the finished product during the lamination process, which leads to problems such as poor appearance, poor edge sealing and poor thickness, seriously affecting work efficiency. Utility Model Content
[0005] The utility model provides a boxed auxiliary packaged aerogel heat insulating pad, which is used to solve the deficiencies described in the above-mentioned prior art.
[0006] The technical solution adopted by the utility model is:
[0007] An aerogel thermal insulation pad with box-mounted auxiliary packaging includes a packaging box, a thermal insulation core material, and an adhesive layer; the packaging box includes a box body and a packaging cover, the box body is provided with a core material placement cavity, an adhesive layer is provided at the bottom of the core material placement cavity, the thermal insulation core material is placed in the core material placement cavity and one working end face of the thermal insulation core material is in contact with the adhesive layer, the inner wall of the packaging cover is provided with an adhesive layer, the packaging cover is located on the box body and covers the core material placement cavity; and the adhesive layer on the packaging cover is in contact with the other working end face of the thermal insulation core material. A split box structure is used as the packaging layer of the thermal insulation core material, the adhesive layer is located in the packaging box, and an adhesive layer with sufficient viscosity can be used. The box packaging method can completely seal the thermal insulation core material to avoid the poor edge sealing state of film packaging.
[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 present utility model, the packaging box is a PET packaging box.
[0010] As a preferred solution of the present invention, the thickness of the packaging box is 0.1-0.5 mm.
[0011] As a preferred solution of the utility model, the packaging box is a PP packaging box.
[0012] As a preferred solution of the utility model, the thickness of the packaging box is 0.25-1 mm.
[0013] As a preferred solution of the utility model, the packaging box is a PE packaging box.
[0014] As a preferred solution of the utility model, the thickness of the packaging box is 0.02-0.06 mm.
[0015] The utility model uses a split box structure as the packaging layer of the heat insulation core material. The glue layer is located in the packaging box. A glue layer with sufficient viscosity can be used. The packaging box itself has low viscosity. The glue layer can be well bonded to the heat insulation core material. The box packaging method can completely seal the heat insulation core material to avoid the poor edge sealing state of film packaging. The packaging box does not need to be stacked in multiple layers. It only needs to put the heat insulation core material into vacuum pressing. The finished product has uniform thickness and neat appearance. The packaging method is simple and improves work efficiency. The thickness of the packaging box varies according to the material. BRIEF DESCRIPTION OF THE DRAWINGS
[0016] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Example:
[0020] A box-installed auxiliary packaged aerogel thermal insulation pad comprises a packaging box 1, a thermal insulation core material 2, and an adhesive layer 3; the thermal insulation core material used can be any material as long as it can achieve thermal insulation, and an aerogel thermal insulation core material is preferably used, and the packaging box 1 comprises a box body 11 and a packaging cover 12, the box body 11 is provided with a core material placement cavity, an adhesive layer 2 is provided at the bottom of the core material placement cavity, the thermal insulation core material 2 is placed in the core material placement cavity and one working end face of the thermal insulation core material contacts the adhesive layer, an inner wall of the packaging cover 12 is provided with an adhesive layer, the packaging cover is located on the box body and covers the core material placement cavity; and the adhesive layer on the packaging cover contacts the other working end face of the thermal insulation core material.
[0021] The placement order is to prepare the packaging box first, and open the packaging cover, place the insulation core material flatly from the top into the core material placement cavity and contact with the glue layer in the core material placement cavity, and the edge of the insulation core material does not contact the side wall of the core material placement cavity, which can avoid friction loss of the edge of the insulation core material, and then cover the packaging cover to make the glue layer contact with the working end face of the insulation core material, and finally apply vacuum negative pressure to make the whole into an insulation pad.
[0022] The packaging box can be made of PET, PP or PE. When PET is used, the thickness is 0.1-0.5mm; when PP is used, the thickness is 0.25-1mm; when PE is used, the thickness is 0.02-0.06mm.
[0023] The use of packaging boxes to package the thermal insulation core material reduces the tolerance for the thickness rebound of the core material due to insufficient adhesive layer adhesion, greatly improving the qualified rate of the product; and according to the packaging object, the packaging structure can be optimized, which can not only ensure the packaging strength, but also reduce the poor appearance and poor edge sealing of the product; it can also effectively control the thickness range of the finished product, greatly improving the finished product yield, and can effectively ensure the packaging strength of different thermal insulation core materials, and ensure the effective use of powder-type thermal insulation core materials.
