[0002] The vehicle refrigerator is used for storing vehicle-related articles, refrigerating and preserving food and wine, and providing convenience for home travel, field camping and work. In recent years, the vehicle refrigerator has been favored by consumers. Under the background of consumption upgrading, the travel quality and life quality of people are changing. The vehicle refrigerator has evolved from a simple storage device to a benchmark for measuring the convenience of a car.

[0003] At present, the installation space of the embedded vehicle refrigerator is usually narrow and limited. In order to facilitate the free opening of the refrigerator door under the driving of the hinge during the opening and closing process, and to ensure that the side wall of the hinge joint during the opening process does not interfere with the environmental part (decorative part) on the refrigerator main body, a certain gap needs to be reserved between the door and the environmental part. If the gap is too large, it may cause the overall appearance of the refrigerator to be uneven. If the gap is too small, it may cause interference with the environmental part when the door is opened and closed, resulting in the door being unable to be fully opened. The traditional hinge is generally a fixed rotating shaft opening and closing hinge. The door with the traditional fixed rotating shaft opening and closing hinge cannot be rotated around the environmental part due to the fixed rotating center, which may cause interference between the door and the environmental part.

[0004] Therefore, the vehicle refrigerator with a variable shaft hinge is proposed to solve the above technical problems. UTILITY MODEL CONTENTS
