Thermal insulation mat

A thermal insulation mat, comprising:

• a main body portion, at least one folded portion, and edge portions, wherein the edge portions are arranged at edges of the main body portion, and the folded portion penetrates through the main body portion;
• the main body portion comprises:
• a first thermal insulation layer, comprising:
• an upper thermal insulation sheet, consisting of a fabric, a coating, and an aluminum foil, wherein the coating is applied between the aluminum foil and the fabric;
• and the upper thermal insulation sheet is configured as a surface of the mat and is configured to contact a heat source;
• a lower thermal insulation sheet, arranged opposite to the upper thermal insulation sheet and consisting of a fabric, a coating, and an aluminum foil, wherein the coating is applied between the aluminum foil and the fabric;
• and the lower thermal insulation sheet is configured a bottom surface of the mat, and the upper thermal insulation sheet and the lower thermal insulation sheet are arranged opposite to each other to form a receiving space;
• and
• a second thermal insulation layer, configured to be located within the receiving space of the first thermal insulation layer, made of a flexible material, and sandwiched between the upper thermal insulation sheet and the lower thermal insulation sheet;
• the upper thermal insulation sheet, the second thermal insulation layer, and the lower thermal insulation sheet are stacked from top to bottom in sequence to form the main body portion;
• and
• the edge portion comprises:
• a connecting strip, wherein the connecting strip is arranged along the edge portion, and the connecting strip fixes the upper thermal insulation sheet, the second thermal insulation layer, and the lower thermal insulation sheet from top to bottom in sequence by way of a stitching thread, such that the upper thermal insulation sheet, the second thermal insulation layer, and the lower thermal insulation sheet are aligned from top to bottom in sequence;
• and
• the upper thermal insulation sheet, the second thermal insulation layer, and the lower thermal insulation sheet are foldable along the folded portion;
• a texture is arranged on the surface of the mat or the bottom surface of the mat and comprises a concave area and a convex area, the concave area and the convex area are arranged adjacent to each other, and a shape of the convex area is at least one of a circle, a triangle, a polygon, an ellipse, and an irregular shape;
• wherein the second thermal insulation layer comprises:
• a second aluminum foil;
• a plastic or a rubber;
• and
• a third aluminum foil, wherein
• the second aluminum foil, the plastic or rubber, and the third aluminum foil are arranged in sequence and are all of sheet structures, wherein the plastic or rubber is sandwiched between the second aluminum foil and the third aluminum foil, and the second aluminum foil, the plastic or rubber, and the third aluminum foil are substantially the same in shape and size;
• wherein a thickness of the upper thermal insulation sheet and a thickness of the lower thermal insulation sheet are both 0.3-0.9 mm, and a thickness of the second thermal insulation layer is 3-12 mm;
• wherein the second aluminum foil and the third aluminum foil are laminated on a surface layer and a bottom layer of a rubber-plastic material to form a double-sided reflecting layer, a continuous sealing layer is formed between the aluminum foil and the rubber-plastic material.
