[0021] In order to make the purpose, technical scheme and advantage of the utility model more clearly, below, combining with specific implementation and referring to the drawings, the utility model is further detailed. It should be understood that these descriptions are only exemplary, and are not intended to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0022] As Figures 1-4 The utility model discloses a kind of vehicle-mounted refrigerator that can prevent internal negative pressure, mainly including refrigerator body 1 and refrigerator cover body 3 composition, refrigerator body 1 as main structure, one side of its top is symmetrically provided with a pair of connecting lug 2, this pair of connecting lug 2 provides key connecting point for the installation of subsequent refrigerator cover body 3, and the tail of refrigerator cover body 3 is equipped with rotating part 30, which is accurately movably arranged between the two connecting lug 2, so that the movable connection of refrigerator cover body 3 and refrigerator body 1 is realized, so that refrigerator cover body 3 can be with rotating part 30 as shaft, relative to the smooth opening and closing action of refrigerator body 1, meet the operation demand of user to refrigerator access article;

[0023] In the bottom of refrigerator cover body 3, sealing body 31 that is perfectly matched with the shape of refrigerator body 1 loading port is provided, the outside of sealing body 31 is closely attached to sealing strip 4, and the top of sealing strip 4 is uniformly distributed with several fixed insertion columns 40, sealing strip 4 is firmly installed at the bottom of refrigerator cover body 3 by these fixed insertion columns 40, to ensure its stability in use process, and the bottom of sealing strip 4 is specially designed with foldable edge 42, and ventilation groove 43 is formed between the foldable edge 42 and sealing strip 4, and simultaneously, one side of sealing strip 4 is also provided with a pair of ventilation openings 41, and these structural designs play an important role in the pressure balance of refrigerator.

[0024] In addition, a circle of protruding rib 10 is arranged around the position corresponding to the foldable edge 42 of sealing strip 4 on the top of refrigerator body 1, when refrigerator cover body 3 is closed, the protruding rib 10 cooperates with the foldable edge 42 of sealing strip 4, and the sealing and pressure regulation function of refrigerator interior is realized ingeniously, which further improves the overall performance and use experience of refrigerator.

[0025] In the use of the refrigerator, when the refrigerator cover 3 is closed, the cover rotates around the rotating part 30, and drives the sealing body 31 to gradually close the loading port of the refrigerator body 1. In this process, the sealing strip 4 on the sealing body 31 first contacts the raised rib 10 on the edge of the loading port of the body, and as the cover continues to close, the raised rib 10 exerts an upward lifting force on the foldable edge 42 of the sealing body 31, so that the foldable edge 42 folds inward, thereby completely blocking the ventilation groove 43, and at the same time, the ventilation opening 41 is also blocked. In this way, the inside of the refrigerator body 1 is effectively isolated from the outside environment, ensuring good sealing of the inside of the refrigerator, helping to maintain a stable low-temperature environment required for refrigeration, preventing cold air leakage, reducing energy consumption, and ensuring the freshness and refrigeration effect of food;

[0026] When the refrigerator cover 3 needs to be opened, the user applies an upward turning external force to the door body. At this time, the foldable edge 42 that was originally lifted and folded quickly recovers and unfolds from the ventilation groove 43 due to the loss of the restriction of the raised rib 10 and the action of its own elasticity. This unfolding action instantaneously enhances the communication between the inside of the refrigerator refrigeration chamber and the outside environment, and the indoor and outdoor air pressures are quickly balanced, effectively eliminating the suction effect on the door body caused by the air pressure difference, so that the door body can be easily and smoothly opened, greatly improving the convenience and experience of the user when using the refrigerator, and avoiding problems such as excessive force that may damage the refrigerator components when the door body is difficult to open.

[0027] It should be understood that the above specific embodiments of the present application are only used for illustrative or explanatory purposes of the principles of the present application, and do not constitute a limitation on the present application. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present application shall be included in the protection scope of the present application. In addition, the appended claims of the present application are intended to cover all changes and modifications falling within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
