Description

Technical Field

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

[0002] With the development of society and the continuous improvement of people's living quality, in order for vehicle users on long-distance trips to enjoy chilled beverages at any time, vehicle manufacturers will install vehicle-mounted refrigerators in vehicles.

[0003] For example, the patent with the publication number CN217636372U discloses a pull-out vehicle-mounted refrigerator that is convenient for taking and placing items while saving space. It includes a box body with an open side, a refrigerating box with an open top is arranged inside the box body, a chute / slider is arranged on the bottom wall of the inner cavity of the box body, the length direction of the chute / slider is located in the horizontal plane and is perpendicular to the plane where the box opening is located, and the slider / chute arranged at the bottom of the refrigerating box forms a sliding fit in the chute length direction with the chute / slider on the bottom wall of the box body. In the above solution, the refrigerating box is slidably arranged inside the box body.

[0004] The problems existing in the above prior art are as follows: The refrigerating box of this refrigerator is slidably arranged inside the box body. In actual situations, in order for the refrigerating box to slide relative to the box body, there is a gap between the refrigerating box and the box body, and the cold air inside the refrigerating box will enter the box body through the gap, and the temperature inside the refrigerating box cannot reach the expected effect, which is likely to cause waste of energy. Moreover, after the refrigerator stops working, the temperature inside the refrigerating box changes rapidly, and the refrigerating effect inside the refrigerating box cannot be guaranteed.

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

[0006] In order to solve the above technical problems, the purpose of the utility model is: a heat-insulating drawer of a vehicle-mounted cooling and heating box, which can prevent cold air from leaking and save energy.

[0007] The technical solution adopted by the utility model to solve the problem is: a heat-insulating drawer of a vehicle-mounted cooling and heating box, including a main body with an opening at the front side. A push-pull box is slidably connected inside the main body. An accommodating cavity with an open top is arranged inside the push-pull box. A heat-insulating plate is rotatably connected to the inner side of the top of the main body. A butt joint part extends downward along the rear side edge of the heat-insulating plate. A spring is arranged between the butt joint part and the inner wall of the main body. When the push-pull box is closed, the rear side wall of the push-pull box abuts against the butt joint part and drives the heat-insulating plate to rotate downward by a certain angle, so that the heat-insulating plate seals the accommodating cavity. When the push-pull box is opened, the spring drives the butt joint part to rotate, so that the heat-insulating plate rotates upward by a certain angle and opens the accommodating cavity.

[0008] As a further improvement of the above technical solution, a shaft rod is provided at the side end of the abutting portion, a shaft hole is provided at the side end of the main body, and the shaft rod is rotatably connected to the shaft hole.

[0009] As a further improvement of the above technical solution, a mounting hole is provided at the side end of the abutting portion, and the shaft rod is fixedly arranged in the mounting hole.

[0010] As a further improvement of the above technical solution, an abutting protrusion is fixedly arranged on the inner side surface of the abutting portion. When the push-pull box is closed, the abutting protrusion abuts against the outer side surface of the push-pull box.

[0011] As a further improvement of the above technical solution, the material of the abutting protrusion is rubber.

[0012] As a further improvement of the above technical solution, the cross-sectional shape of the heat preservation plate is L-shaped.

[0013] As a further improvement of the above technical solution, an annular groove is arranged around the bottom surface of the heat preservation plate, and a sealing ring is arranged in the annular groove. When the push-pull box is closed, the sealing ring abuts against the top edge of the accommodating cavity.

[0014] The beneficial effects of the present utility model are as follows: When the push-pull box is closed, the rear side wall of the push-pull box abuts against the abutting portion and drives the heat preservation plate to rotate downward by a certain angle, so that the heat preservation plate seals the accommodating cavity, which can effectively prevent the cold air in the accommodating cavity from flowing out. After the refrigerator stops working, it can play a heat preservation role, slow down the temperature change in the accommodating cavity, extend the refrigeration effect of the items in the accommodating cavity, and at the same time achieve the effect of saving energy. When the push-pull box is opened, the spring drives the heat preservation plate to rotate 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 sense of jerk generated by the user when pulling the push-pull box, and can give the user a better use experience.
