Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted refrigerators, in particular to a heat preservation structure of a vehicle-mounted cooling and heating box. Background Art

[0002] With the development of society and the continuous improvement of people's quality of life, automobile companies will install on-board refrigerators in cars so that car users on long-distance trips can enjoy iced drinks at any time.

[0003] For example, the patent with publication number CN217636372U discloses a pull-out car refrigerator that is convenient for taking and placing while saving space. It includes a box with an open side, a refrigerated box with an open top is arranged in the box, and a slide groove / slider is provided on the bottom wall of the inner cavity of the box. The length direction of the slide groove / slider is located in the horizontal plane and is arranged perpendicular to the surface where the box opening is located. The slider / slide groove provided on the bottom of the refrigerated box and the slide groove / slider on the bottom wall of the box form a sliding fit in the length direction of the groove. In the above scheme, the refrigerated box is slidably arranged in the box.

[0004] The problem with the above-mentioned prior art is that the refrigerator box of the refrigerator is slidably arranged in the box body. In actual conditions, in order for the refrigerator box to slide relative to the box body, there is a gap between the refrigerator box and the box body. The cold air in the refrigerator box will enter the box body through the gap. The temperature in the refrigerator box cannot reach the expected effect, which easily causes energy waste. Moreover, after the refrigerator stops working, the temperature in the refrigerator box changes rapidly, and the refrigeration effect in the refrigerator box cannot be guaranteed.

[0005] Therefore, a thermal insulation structure of a vehicle-mounted cooling and heating box is proposed to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the purpose of the present invention is to provide a thermal insulation structure for a vehicle-mounted cooling and heating box, which can prevent the loss of cold air and save energy.

[0007] The technical solution adopted by the utility model to solve the problem is: an insulation structure of a vehicle-mounted cooling and heating box, including a main body with an opening on the front side, a push-pull box slidably connected to the main body, a accommodating cavity with an upper opening is provided in the push-pull box, and also including a heat preservation plate and a connecting rod, the end of the connecting rod is rotatably connected to the top of the main body, and the other end of the connecting rod is rotatably connected to the heat preservation plate, a torsion spring is provided between the connecting rod and the main body, and the rear side edge of the heat preservation plate extends downward with an abutment portion; when the push-pull box is closed, the rear side wall of the push-pull box abuts against the abutment portion and drives the heat preservation plate to rotate downward by a certain angle, so that the heat preservation plate is blocked in the accommodating cavity; when the push-pull box is opened, the torsion spring drives the connecting rod to rotate so that the heat preservation plate rotates upward by a certain angle and opens the accommodating cavity.

[0008] As a further improvement of the above technical solution, a mounting groove is provided on the top of the main body, a first shaft rod is provided in the mounting groove, the end of the connecting rod is rotatably connected to the first shaft rod, and the torsion spring is sleeved on the first shaft rod; a second shaft rod is provided on the outer edge of the insulation board, and the other end of the connecting rod is rotatably connected to the second shaft rod.

[0009] As a further improvement of the above technical solution, an abutting protrusion is fixedly provided on the inner side surface of the abutting portion, and when the push-pull box is closed, the abutting protrusion abuts against the outer side surface of the push-pull box.

[0010] As a further improvement of the above technical solution, the abutting protrusion is made of rubber.

[0011] As a further improvement of the above technical solution, the cross-section of the insulation board is L-shaped.

[0012] As a further improvement of the above technical solution, an annular groove is provided around the bottom surface of the insulation board, and a sealing ring is provided in the annular groove. When the push-pull box is closed, the sealing ring abuts against the top edge of the accommodating cavity.

[0013] The beneficial effects of the present invention are as follows: when the push-pull box is closed, the rear side wall of the push-pull box abuts against the abutment and drives the insulation plate to rotate downward by a certain angle, so that the insulation plate is sealed in the accommodating cavity, which can effectively prevent the loss of cold air in the accommodating cavity. After the refrigerator stops working, it can start the insulation effect, slow down the temperature change in the accommodating cavity, prolong the refrigeration effect of the items in the accommodating cavity, and save energy at the same time. When the push-pull box is opened, the torsion spring drives the connecting rod to rotate so that the insulation plate rotates upward by a certain angle and opens the accommodating cavity, which can prevent the damping of opening the push-pull box from being too large, reduce the user's sense of frustration when pulling the push-pull box, and give the user a better user experience.
