Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted refrigerators, in particular to a thermal insulation structure of a vehicle-mounted cold and warm 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 and saves space, including a box with an open side, a refrigerated box with an open top is arranged in the box, and a slide groove / slider is arranged 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 arranged at 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 refrigeration box of the refrigerator is slidably arranged in the box body. In actual conditions, in order for the refrigeration box to be able to slide relative to the box body, there is a gap between the refrigeration box and the box body. The cold air in the refrigeration box will enter the box body through the gap. The temperature in the refrigeration box cannot reach the expected effect, which easily causes energy waste. After the refrigerator stops working, the temperature in the refrigeration box changes rapidly, and the refrigeration effect in the refrigeration box cannot be guaranteed.

[0005] Therefore, a thermal insulation structure of a vehicle-mounted cold and warm 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 utility model is to provide a thermal insulation structure of a vehicle-mounted cold and warm 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 cold and warm 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 arranged in the push-pull box, and an insulation component and a power mechanism movably connected to the inner side of the top of the main body; when the push-pull box is closed, the power mechanism drives the insulation plate to move downward a certain distance and seal the accommodating cavity; when the push-pull box is opened, the power mechanism drives the insulation plate to move upward a certain distance and open the accommodating cavity.

[0008] As a further improvement of the above technical solution, the power mechanism includes a pressure spring and a driving rod, the pressure spring is obliquely arranged between the main body and the insulation board, one end of the pressure spring is fixedly connected to the inner wall of the main body, and the other end of the pressure spring is fixedly connected to the rear side wall of the insulation board; the driving rod is fixedly connected to the insulation board, the driving rod is rotatably connected to the inner side of the top of the main body, and the lower end of the driving rod is provided with an abutment, which is located on the outside of the push-pull box; when the push-pull box is closed, the rear side surface of the push-pull box abuts against the abutment, and the pressure spring is squeezed by the insulation board; when the push-pull box is opened, the rear side surface of the push-pull box is disengaged from the abutment, and the insulation board moves obliquely upward under the influence of the elastic force of the pressure spring, and the insulation board opens the accommodating cavity.

[0009] As a further improvement of the above technical solution, the top of the main body is recessed inwardly with an installation groove, the end of the driving rod is rotatably connected in the installation groove, the rear end of the insulation board is provided with a through groove, the middle part of the driving rod is fixedly connected to the inner wall of the through groove, and the abutment portion is located below the through groove.

[0010] As a further improvement of the above technical solution, the driving rod is U-shaped as a whole.

[0011] As a further improvement of the above technical solution, an abutting protrusion is fixedly connected to 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, and the material of the abutting protrusion is rubber.

[0012] As a further improvement of the above technical solution, a groove is arranged around the bottom of the insulation board, a sealing ring is arranged in the groove, and the sealing ring abuts against the top edge of the push-pull box.

[0013] The beneficial effects of the present utility model are as follows: when the push-pull box is closed, the power mechanism drives the heat-insulating component to move downward a certain distance to block the accommodating cavity, which can effectively prevent the loss of cold air in the accommodating cavity. After the refrigerator stops working, the heat-insulating effect can be started to 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 power mechanism drives the heat-insulating component to move upward a certain distance and open 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.
