Description

Technical Field

[0001] The utility model relates to a refrigerator, in particular to a plug-in position detection structure of a plug-in vehicle-mounted refrigerator. Background Art

[0002] With the development of social economy and automobile industry, the comfort requirements of vehicles are gradually increasing. In order to provide passengers with cool drinks or fresh food refrigeration and freezing functions during the journey, some cars are designed with on-board refrigerators during the body design, integrating the on-board refrigerator with the interior space and structure of the car, that is, front-mounted car refrigerators. This kind of front-mounted refrigerator needs to be integrated into the design during the early stage of the car design, and generally has a small volume and a fixed position, and cannot be used without the car; there are also portable car refrigerators in existing products, that is, rear-mounted car refrigerators. Existing portable car refrigerators cannot be simply fixed on the car. To prevent tipping, most of them are fixed on the car through additional mechanical connections. Car refrigerators can be powered on or charged and discharged with the car. The plug interface of the car refrigerator may not be properly plugged into the plug interface on the car during installation. During the driving process of the car, the plug interface of the car refrigerator and the plug interface on the car may also be displaced, resulting in a misconnection, resulting in the refrigerator being unable to refrigerate normally.
