[0002] The common vehicle-mounted refrigerator inner cavity is a cavity, so that the temperature inside the cavity is relatively uniform. When the items placed inside need to be stored at different temperatures, it is not possible to achieve this. Therefore, a dual-temperature-cavity vehicle-mounted refrigerator appears to store items with different temperature storage requirements. However, the space inside the car is limited, and when the items do not need to be stored at different temperatures, the dual-temperature-cavity vehicle-mounted refrigerator will have one cold storage cavity idle, resulting in a waste of space and additional energy consumption. How to optimize the idle cold storage cavity of the dual-temperature-cavity vehicle-mounted refrigerator has become a new difficulty. CONTENT OF THE UTILITY MODEL

[0006] A cover member is movably connected to the temperature insulation plate. By adjusting the relative position of the cover member and the temperature insulation plate, the opening and closing states of the first through hole in the temperature insulation plate can be switched.

[0007] When the first through hole is in an open state, the strong cooling area and the weak cooling area realize air flow exchange through the first through hole, and the temperatures of the two areas gradually become consistent.

[0009] According to the technical scheme provided by some embodiments of the present application, the temperature insulation plate and the cover member are mutually attached and are relatively slidably connected.

[0010] A second through hole is formed in the cover member and is opposite to the first through hole. When the cover member is slid to the first through hole and the second through hole are in communication, the first through hole is in an open state. When the cover member is slid to the first through hole and the second through hole are completely misaligned, the first through hole is in a closed state.

[0011] According to the technical scheme provided by some embodiments of the present application, a sliding groove is arranged on the temperature insulation plate, and the cover member is connected with the temperature insulation plate through the sliding groove.

[0012] According to the technical scheme provided by some embodiments of the present application, a limiting block is arranged on the temperature insulation plate, and the limiting block protrudes from the surface of the temperature insulation plate.

[0019] The cover plate is arranged at the opening of the receiving shell, and is used for closing the opening of the receiving shell.

[0020] According to the technical scheme provided by some embodiments of the present application, the cover plate is connected with the receiving shell.

[0021] According to the technical scheme provided by some embodiments of the present application, a sealing strip is further arranged at the edge of the temperature insulation plate which is in contact with the wall of the installation position.

[0030] In the first through hole opening state, the strong cooling area and the weak cooling area realize air flow intercommunication through the first through hole, and the temperatures of the two areas gradually keep consistent;

[0031] In the first through hole closing state, the strong cooling area and the weak cooling area are separated by the thermal insulation plate, and the two areas maintain their original temperatures.

[0047] A cover piece 2 is movably connected with the thermal insulation plate 1, and the opening and closing states of the first through hole 11 in the thermal insulation plate 1 are switched by adjusting the relative position of the cover piece 2 and the thermal insulation plate 1;

[0048] In the open state of the first through hole 11, the strong cooling area 3 and the weak cooling area 4 realize air flow intercommunication through the first through hole 11, and the temperatures of the two areas gradually keep consistent;

[0051] In a preferred embodiment, the thermal insulation plate 1 and the cover piece 2 are mutually attached and relatively slidably connected.​

[0052] The cover member 2 is provided with a second through hole 21 opposite to the first through hole 11; the cover member 2 is slid to the first through hole 11 and the second through hole 21 is in communication, and the first through hole 11 is in an open state; the cover member 2 is slid to the first through hole 11 and the second through hole 21 is completely misaligned, and the first through hole 11 is in a closed state.

[0053] In a preferred embodiment, the first through hole 11 and the second through hole 21 are arranged in pairs, and there are multiple groups;

[0054] The distance between adjacent second through holes 21 on the cover member 2 is greater than the diameter of the first through hole 11, which ensures that the cover member 2 can completely block the first through hole 11.

[0055] Optionally, the cross-sectional shape and size of the first through hole 11 and the second through hole 21 are the same. The first through hole 11 and the second through hole 21 are selected to be flat openings, such as oval, crescent, rectangle, etc. (This application takes oval through holes as an example for specific description, wherein the "long axis" of the oval is the longest diameter, and the "short axis" of the oval is the shortest diameter.) The first through holes 11 are arranged at intervals on the temperature insulation plate 1, the extension directions of the first through holes 11 are parallel to each other, the extension directions of the short axes of the first through holes 11 are the same, and the distance between adjacent first through holes 11 is greater than the length of the short diameter of the first through hole 11.

[0057] In a preferred embodiment, a limiting block 17 is arranged on the temperature insulation plate 1, and the limiting block 17 protrudes from the surface of the temperature insulation plate 1;

[0058] In the length direction of the sliding groove 15, the limiting block 17 is arranged at the front end and / or the rear end of the sliding groove 15, which is used to prevent the cover member 2 from being separated from the temperature insulation plate 1.

[0059] Optionally, the upper surface of the temperature insulation plate 1 is provided with two parallel sliding grooves 15, which are arranged on the left and right sides of the temperature insulation plate 1 respectively, and the distance between the two sliding grooves 15 is equal to the length of the cover 2. The cover 2 slides relative to the sliding grooves 15 in the width direction of the cover 2 (the width direction of the cover 2 is the length direction of the two sliding grooves 15). The openings of the two sliding grooves 15 are arranged opposite to each other in the extension plane of the cover 2, and the edges of the cover 2 are covered by the C-shaped sliding grooves 15 to prevent the cover 2 from separating from the temperature insulation plate 1 in the upward direction.

The two sliding grooves 15 are arranged opposite to each other in the left and right directions to prevent the cover 2 from separating from the temperature insulation plate 1 in the left and right directions. In addition, limiting blocks 17 are arranged at the front and rear ends of the sliding grooves 15 to prevent the cover 2 from sliding too far in the front and rear directions and separating from the temperature insulation plate 1.

[0060] Specifically, the sliding grooves 15 extend in a C-shaped trajectory and cover the left, right and front edges of the cover 2. Among them, the left and right sliding grooves 15 are parallel to each other, and the cover 2 slides in the front and rear directions of the cover 2 under the limitation of the left and right sliding grooves 15; the front sliding groove acts as a limiting block 17 to prevent the cover 2 from separating from the temperature insulation plate 1 from the front side. In addition, limiting blocks 17 are arranged at the opening direction of the C-shaped sliding groove, i.e. the rear side of the cover plate 14, and the limiting blocks 17 are fixedly connected with the temperature insulation plate 1 to prevent the cover 2 from separating from the temperature insulation plate 1 in the rear direction.

[0063] The foaming body is filled in the receiving cavity of the receiving shell 13.

[0064] The cover plate 14 is arranged at the opening of the receiving shell 13 to seal the opening of the receiving shell 13.

[0065] Specifically, the receiving shell 13 is provided with a vertical pipe 16 vertically arranged with an upper and lower opening, and the inner diameter of the vertical pipe 16 constitutes the first through hole 11 on the thermal insulation plate 1.

The upper end of the vertical pipe 16 is inserted into the opening of the cover plate 14. The outer diameter of the upper end of the vertical pipe 16 is provided with a boss, which is circumferentially arranged around the vertical pipe 16. When the cover plate 14 is covered on the opening of the receiving shell 13, the upper surface of the boss on the upper end of the vertical pipe 16 abuts against the lower surface of the cover plate 14.

On the other hand, it enhances the sealing between the vertical pipe 16 and the cover plate 14. Optionally, a sealing ring is arranged between the vertical pipe 16 and the opening on the cover plate 14.

[0066] In a preferred embodiment, the cover plate 14 is clamped with the receiving shell 13. Specifically, the shape of the outer edge of the cover plate 14 is consistent with the shape of the opening of the receiving shell 13, and the two are inserted into each other. The circumferential edge of the cover plate 14 is provided with a reverse triangular boss, and the inner side wall of the receiving shell 13 is provided with a groove matched with the reverse triangular boss, to prevent the cover plate 14 from being separated from the receiving shell 13 after assembly. The circumferential edge of the cover plate 14 is provided with a limiting boss, and the outer diameter of the boss is larger than the inner diameter of the opening of the receiving shell 13, to prevent the cover plate 14 from falling into the receiving shell 13.

[0068] In a preferred embodiment, the cover member 2 is also fixedly provided with a wrench 22, which is arranged on the side of the cover member 2 away from the thermal insulation plate 1 and protrudes from the outer surface of the cover member 2. The user can realize the relative movement of the cover member 2 relative to the thermal insulation plate 1 by manually rotating the wrench 22.

[0069] Optionally, a mechanical driving member is arranged between the thermal insulation plate 1 and the cover member 2. The mechanical driving member includes a controller and a contraction lever. The two ends of the contraction lever are respectively connected with the thermal insulation plate 1 and the cover member 2, and the contraction lever is electrically connected with the controller. The user can control the contraction of the contraction lever by the controller to switch the opening and closing states of the first through hole 11. In addition, a motor lead screw, a servo motor or the like can be used.

[0071] A vehicle-mounted refrigerator, wherein the vehicle-mounted refrigerator temperature adjusting device is arranged between the strong cooling area 3 and the weak cooling area 4. In the closed state of the first through hole 11, the temperature of the strong cooling area 3 is lower than that of the weak cooling area 4.

[0072] Optionally, the strong cooling area 3 and the weak cooling area 4 share one refrigeration compressor, the density of the refrigeration pipeline arrangement in unit area is greater, the refrigeration effect is stronger; the arrangement density of the refrigeration pipeline of the strong cooling area 3 is greater than the arrangement density of the refrigeration pipeline of the weak cooling area 4, and the refrigeration temperature of the strong cooling area 3 is lower than the refrigeration temperature of the weak cooling area 4. And / or,

[0073] The strong cooling area 3 and the weak cooling area 4 share one refrigeration compressor, the refrigeration pipeline in unit area, the smaller the space to be refrigerated, the stronger the refrigeration effect; the internal space of the strong cooling area 3 is smaller than the internal space of the weak cooling area 4, and the refrigeration temperature of the strong cooling area 3 is lower than the refrigeration temperature of the weak cooling area 4.

[0074] Optionally, the vehicle-mounted refrigerator is equipped with two independent refrigeration systems, the strong cooling area 3 and the weak cooling area 4 are independently cooled by the respective refrigeration systems.

[0075] Optionally, the refrigeration system of the vehicle-mounted refrigerator only performs refrigeration operation on the strong cooling area 3. The weak cooling area 4 only plays a role of a heat preservation room, and a temperature detection system is arranged in the weak cooling area 4. According to the use requirement, when the weak cooling area 4 needs to obtain a lower temperature, the first through hole 11 on the temperature adjusting device of the vehicle-mounted refrigerator is opened; when the temperature in the weak cooling area 4 reaches the use requirement, the first through hole 11 is closed; when the temperatures of the strong cooling area 3 and the weak cooling area 4 need to be the same, the first through hole 11 is kept in an open state.

[0076] In a preferred embodiment, the strong cooling area 3 is arranged above the weak cooling area 4, so that after the first through hole 11 on the temperature adjusting device of the vehicle-mounted refrigerator is opened, the cold air in the strong cooling area 3 falls to the weak cooling area 4 under the action of its own gravity.
