Refrigerator door body heat preservation structure

The utility model belongs to the technical field of vehicle-mounted refrigerators, and particularly relates to a refrigerator door body heat preservation structure, a heat preservation core material is arranged in a cavity defined by a bottom shell and a top shell, the heat preservation core material comprises a concave part, and a core body on the side or the peripheral side of the concave part is in extrusion fit with the bottom shell and the top shell in the thickness direction of a door body. In the production process, the heat preservation core material and the refrigerator shell can be machined respectively, the foaming forming time does not need to be waited, the door shell does not need to be assembled and disassembled on a foaming mold, the production efficiency is greatly improved, and the bad appearance caused by collision and scratching can be effectively avoided. In addition, the heat preservation core material can be separated from the refrigerator door body shell, and maintenance of the refrige
