[0022] The present utility model will be further described below with reference to the drawings and embodiments.

[0023] Refer to Figures 1-6 , this heat preservation structure includes a box body 1 and an inner liner 2 provided in the box body 1, and further includes a heat preservation board 3 and a foaming layer. The heat preservation board 3 surrounds the outer peripheral side of the inner liner 2. A foaming area 4 is formed between the box body 1 and the heat preservation board 3. A foaming layer is provided in the foaming area 4. The heat preservation board 3 is pressed between the inner liner 2 and the foaming layer. The foaming layer is foam. A foam injection port communicating with the foaming area 4 is provided on the box body 1.

[0024] The heat preservation board 3 is integrally formed and forms a frame structure. The heat preservation board 3 is sleeved on the outer periphery of the inner liner 2 through the frame structure. The integral formation of the heat preservation board 3 is beneficial to mass production and has relatively high structural strength.

[0025] Alternatively, multiple heat preservation boards 3 are separately arranged. Each heat preservation board 3 is respectively arranged on the outer peripheral side of the inner liner 2. The separate arrangement of the heat preservation boards 3 provides more flexible installation.

[0026] The heat preservation board 3 of this embodiment is preferably integrally formed.

[0027] The inner side of the heat preservation board 3 is mutually attached to the outer side of the inner liner 2, which can further reduce the loss of cold air inside the refrigerator and improve the refrigeration efficiency of the refrigerator.

[0028] The heat preservation board 3 is pasted or fixed on the inner liner 2 through fasteners (screws). The heat preservation board 3 of this embodiment is pasted and fixed on the inner liner 2. The pasting method is convenient for installation and has high assembly efficiency.

[0029] The heat preservation board 3 is a vacuum insulation panel, namely a VIP board. The vacuum insulation panel is composed of a filled core material and a vacuum protection surface layer. It effectively avoids heat transfer caused by air convection, so the thermal conductivity can be greatly reduced. The combination of the vacuum insulation panel + the foaming layer can effectively reduce the loss of cold air inside the inner liner 2, enabling the refrigerator to achieve the maximum heat preservation effect in a limited space. The VIP board can effectively reduce the heat loss inside the refrigerator, maintain the low-temperature environment inside the refrigerator, and extend the refrigeration effect of the refrigerator. Compared with the traditional heat preservation method that only uses foaming materials, the addition of the VIP board greatly improves the overall heat preservation performance, making it difficult for cold air to leak out and keeping the temperature inside the refrigerator more stable. In addition, by combining the use of the VIP board and the foaming layer, the thickness of the heat preservation layer can be reduced while maintaining an excellent heat preservation effect, thereby reducing the overall floor area of the refrigerator. Because the space inside the vehicle is limited, adopting this structural design makes the vehicle-mounted refrigerator more compact and practical under the same heat preservation effect.

[0030] This new energy vehicle-mounted refrigerator includes this heat preservation structure.

[0031] It further includes a door body assembly. The door body assembly is arranged on the front side of the box body 1 and the inner liner 2. It includes a door body 5 and a door frame 6. The door frame 6 is arranged between the door body 5 and the inner liner 2. A blocking part 7 is arranged on the door frame 6. The blocking part 7 is located in front of the foaming area 4. The door body 5 and the foaming area 4 are separated by the blocking part 7. The blocking part 7 can prevent the foaming foam from leaking to the door body 5 through the opening of the inner liner 2.

[0032] An extension part 8 is arranged on the front side opening of the inner liner 2. One end of the blocking part 7 is provided with a blocking portion 9. The blocking portion 9 overlaps on the extension part 8 and extends horizontally along the inner side of the extension part 8 to form a sealing structure for blocking the foam from entering the inner liner 2, that is, preventing the foaming foam from leaking into the inner liner 2 through the opening of the inner liner 2.

[0033] A seal 10 is provided between the barrier portion 7 and the door body 5. An installation groove 11 is provided on the door body 5, and the seal 10 is installed on the installation groove 11. The seal 10 can seal the gap between the door body 5 and the door frame 6, preventing the cold air inside the inner container 2 from leaking out of the refrigerator through the gap between the door body 5 and the door frame 6.
