Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted refrigerators, and particularly relates to a sealing assembly of a vehicle-mounted refrigerator. Background Art

[0002] With the development of the automotive industry and the improvement of people's living standards, vehicle-mounted refrigerators, as important equipment in outdoor activities such as traveling and camping, are increasingly favored by consumers. To ensure the refrigeration effect of food or beverages, a vehicle-mounted refrigerator must have good heat preservation performance, and a key link is the sealing performance between the box body and the box cover.

[0003] Existing vehicle-mounted refrigerators usually use fixed sealing strips to seal the box body. This design aims to prevent cold air from leaking out to maintain a low-temperature environment inside the refrigerator. However, in actual use, this sealing method often faces a dilemma: on the one hand, if the sealing force provided by the sealing strip is too large, although it can effectively prevent cold air leakage, it may bring inconvenience to users. For example, users need to apply greater force when closing the refrigerator door, which not only may affect the user experience but may also pose operational difficulties for some people. On the other hand, if the sealing force is reduced to facilitate users to close the refrigerator door, it may not be possible to ensure sufficient sealing. This will cause cold air to gradually leak, thereby affecting the refrigeration efficiency of the refrigerator, increasing energy consumption, and even affecting the freshness and safety of food. How to ensure the sealing effect while reducing the force required for users to close the refrigerator door is an issue that people in this field have been discussing.

[0004] The present utility model is made based on the above situation. Summary of the Utility Model

[0027] The following further describes the present utility model in conjunction with the drawings:

[0028] As Figures 1 to 7A sealing assembly of a vehicle-mounted refrigerator as shown includes a box body 1 with an open top. A left box cover 2 is hinged to the left side of the upper end of the box body 1, and a right box cover 3 is hinged to the right side of the upper end of the box body 1. When the left box cover 2 and the right box cover 3 are closed, a sealing structure is provided between the left box cover 2 and the right box cover 3 to seal the gap therebetween. The sealing structure includes a first sealing roller 4 rotatably connected to the right side of the left box cover 2 and a second sealing roller 5 rotatably connected to the left side of the right box cover 3. The first sealing roller 4 and the second sealing roller 5 can rotate in opposite directions by squeezing when the left box cover 2 and the right box cover 3 are closed to seal the gap.

[0029] In this case, when the left box cover 2 and the right box cover 3 are closed, the first sealing roller 4 and the second sealing roller 5 are pressed against each other and rotate in opposite directions. After the left box cover 2 and the right box cover 3 are closed, the first sealing roller 4 and the second sealing roller 5 are pressed against each other to seal the gap between the left box cover 2 and the right box cover 3, thereby preventing the cold air in the refrigerator from leaking. Compared with the sliding friction of the fixed sealing strip when the existing refrigerator door is closed, the frictional resistance of the rolling friction between the first sealing roller 4 and the second sealing roller 5 will be greatly reduced, so that the refrigerator door can be closed with a smaller force, and at the same time, the sealing material on the surfaces of the first sealing roller 4 and the second sealing roller 5 is not easily worn and has a longer service life.

[0030] Specifically, the first sealing roller 4 includes a first roller shaft 41 rotatably connected to the left box cover 2 and a first elastic sealing sleeve 42 sleeved outside the first roller shaft 41.
