[0044] Implementation methods of this application

[0045] As shown in Figures 1 to 31, according to a first aspect of this application, the provided vehicle refrigerator includes: a first housing 10 having a first receiving cavity 11, and the first housing 10 having a first opening 12 communicating with the first receiving cavity 11; and a second housing 20 having a second receiving cavity 21, and the second housing 20 being detachably connected to the first housing 10.

[0046] The above technical solution sets the vehicle refrigerator as two shells, and the first receiving cavity 11 and the second receiving cavity 21 are interconnected to form an internal circulation channel. When the space inside the vehicle is insufficient, since the second shell 20 is detachably connected to the first shell 10, only the second shell 20 needs to be removed to convert the two refrigerators into a single refrigerator. This enables the conversion between a single-layer refrigerator and a double-layer refrigerator, making the refrigerator compatible with more vehicle models, greatly saving production and manufacturing costs, and meeting the user's needs.

[0047] Optionally, the second housing 20 includes an outer shell, the lower part of which is provided with a flange structure, and the second housing 20 is detachably connected to the first housing 10 through the flange structure. The above structure is simple and easy to manufacture, which not only reduces the manufacturing difficulty of the outer shell, but also facilitates the assembly and disassembly of the second housing 20 and the first housing 10.

[0048] Optionally, the second housing 20 is connected to the first housing 10 by screws. Screw connections are relatively simple to operate, requiring only basic torque tools to join threaded components such as screws. This connection method does not require complex equipment or specialized knowledge, making installation and disassembly easy. Furthermore, screw connections are not permanent, meaning they can be disassembled and reused as needed. This is particularly useful for maintenance, quick inspections, or parts replacement, and also improves resource utilization.

[0049] Optionally, the vehicle refrigerator 1 further includes an air supply assembly 30, which connects the first receiving cavity 11 and the second receiving cavity 21. This enables the double-layer refrigerator to function normally, meeting the usage requirements of the vehicle refrigerator 1.

[0050] Optionally, the air supply assembly 30 includes a flow guide 32, which includes a flow guide channel 321. The two ends of the flow guide channel 321 are respectively connected to the first receiving cavity 11 and the second receiving cavity 21. By setting the above structure, the gas can flow in a directional manner, which can improve the gas flow efficiency between the first receiving cavity 11 and the second receiving cavity 21, thereby facilitating the cooling or heating of the vehicle refrigerator 1.

[0051] Optionally, the air supply assembly 30 further includes a fan 31, which has an air inlet 311 and an air outlet 312. One end of the flow guide channel 321 is connected to one of the air inlet 311 or the air outlet 312, and the other of the air inlet 311 or the air outlet 312 is connected to the first receiving cavity 11. The other end of the flow guide channel 321 is used to connect to the second receiving cavity 21. Through the above technical solution, the vehicle refrigerator 1 is configured with two shells, and the first receiving cavity 11, the second receiving cavity 21, the first opening 12, and the flow guide channel 321 are interconnected to form an internal circulation channel. Combined with the air supply function of the fan 31, the gas circulation between the two shells can be realized to meet the heating and cooling functions of the two shells.

[0052] Optionally, the first housing 10 is provided with a first opening 12 communicating with the first receiving cavity 11, and the bottom of the second housing 20 is provided with a second opening 22 corresponding to the first opening 12. When the first housing 10 and the second housing 20 are connected, the first receiving cavity 11 and the second receiving cavity 21 are connected through the first opening 12 and the second opening 22. This arrangement can meet the gas flow requirements between the first housing 10 and the second housing 20, thereby ensuring the normal use of the vehicle refrigerator 1.

[0053] Optionally, the vehicle refrigerator 1 further includes a partition 40, which is disposed between the first housing 10 and the second housing 20, and the first receiving cavity 11 and the second receiving cavity 21 are selectively connected through the partition 40. By setting the above structure, the vehicle refrigerator 1 can switch between single-layer and double-layer configurations, thereby improving the applicability and scope of application of the vehicle refrigerator 1.

[0054] Optionally, the partition 40 is provided with an opening 41 that communicates with the first opening 12 and the second opening 22, and the opening 41 is correspondingly arranged with the first opening 12 and the second opening 22. The first receiving cavity 11 and the second receiving cavity 21 are connected through the opening 41. By setting the above structure, hot and cold air can circulate between the first receiving cavity 11 and the second receiving cavity 21, so that the first receiving cavity 11 and the second receiving cavity 21 can achieve the cooling and heating effect simultaneously to meet the user's needs.

[0055] Optionally, the vehicle refrigerator also includes a cover plate 100, which is used to cover the first opening 12 after the second housing 20 is disassembled from the first housing 10. When there is insufficient space in the vehicle and only one refrigerator is needed, the second housing 20 can be disassembled, and other components can be used to block the connecting ventilation channel between the two inner liner to prevent foreign objects from entering and energy loss. Finally, a cover plate 100 can be reinstalled on the outside, and the two refrigerators can be converted into a single refrigerator. This can improve the applicability and scope of the device to meet the user's needs.

[0056] Optionally, the vehicle refrigerator also includes a cover plate 100. After the second housing 20 is disassembled from the first housing 10, the cover plate 100 covers the other end of the flow channel 321 and the first opening 12. The other end of the flow channel 321 is connected to the first receiving cavity 11 through the first opening 12. By setting the above structure, when the second housing 20 is disassembled from the first housing 10, the vehicle refrigerator is a single-layer refrigerator. At this time, the flow channel 321 can be used to connect the first inner liner 13 with the first receiving cavity 11, so that the gas in the first inner liner 13 can be circulated to improve the cooling and heating effect of the vehicle refrigerator.

[0057] Optionally, the second housing 20 further includes a second inner liner 23 having a second receiving cavity 21, and the first receiving cavity 11 being connected to the second receiving cavity 21. This configuration not only allows the second inner liner 23 to maintain the temperature within the second receiving cavity 21, but also provides a second opening 22 to allow communication between the first receiving cavity 11 and the second receiving cavity 21, thereby meeting the usage requirements of a double-layer refrigerator.

[0058] Optionally, the partition 40 includes: a body 42 having an opening 41; a first protruding structure 43 disposed on one side of the body 42, and the first protruding structure 43 is arranged circumferentially along the body 42, the first protruding structure 43 being used for limiting engagement with the second inner liner 23; and a second protruding structure 44 disposed on the other side of the body 42, and the second protruding structure 44 being arranged circumferentially along the opening 41, the second protruding structure 44 being used for limiting engagement with the first housing 10. This arrangement can improve the tightness of the connection between the partition 40 and the first housing 10 and the second inner liner 23, ensuring the normal operation of the vehicle refrigerator 1.

[0059] Optionally, the thickness at the opening 41 of the partition 40 is greater than the thickness of the rest of the partition 40. This arrangement facilitates the fitting of the partition 40 with the first housing 10 and the second inner liner 23, thereby improving installation efficiency.

[0060] Optionally, the first housing 10 includes a first inner liner 13, which has a first receiving cavity 11 and a first opening 12. The vehicle refrigerator 1 also includes an inner liner cover 14, which is disposed above the first inner liner 13. The inner liner cover 14 has an inner liner opening 15 corresponding to the first opening 12, and a second protruding structure 44 is used to limit and cooperate with the inner liner opening 15. This arrangement ensures the tightness of the connection between the partition 40 and the first inner liner 13, thereby ensuring the normal operation of the vehicle refrigerator 1.

[0061] Optionally, at least one end of the air guide 32 is provided with a filter 50, which covers the opening of the air guide channel 321. This arrangement allows the filter 50 to filter out dust, particles, and other impurities from the air, preventing these impurities from entering and accumulating within the air guide channel 321. This effectively reduces the risk of blockage in the air guide channel 321, ensuring smooth airflow. Blockage in the air guide channel 321 leads to poor airflow, which in turn affects the operating efficiency of the equipment. The use of the filter 50 can prevent this from happening, thus ensuring the equipment can operate continuously and efficiently.

[0062] Meanwhile, impurities and particulate matter in the flow channel 321 may cause wear and corrosion to the inner wall of the flow channel 321 and the inside of the equipment, thereby shortening the service life of the equipment. The use of filter screen 50 can reduce the damage of these impurities to the equipment, thereby extending the service life of the equipment.

[0063] Optionally, the vehicle refrigerator further includes: a drawer 60, movably disposed within the first receiving cavity 11, the drawer 60 having a first ventilation hole 61; wherein the first ventilation hole 61 is disposed corresponding to the air inlet 311, and the area of ​​the first ventilation hole 61 is larger than the area of ​​the air inlet 311, or the first ventilation hole 61 is disposed corresponding to the air outlet 312, and the area of ​​the first ventilation hole 61 is larger than the area of ​​the air outlet 312.

[0064] Through the above technical solution, when the vehicle refrigerator is turned on for cooling or heating, the fan 31 blows air, which causes the cold or hot air in the first receiving cavity 11 to circulate rapidly. Some of the air will pass through the first ventilation hole 61, and some air will flow into the drawer 60 through the gap between the drawer 60 and the first receiving cavity 11. The air inside the drawer 60 will then enter through the air inlet 311 of the fan 31. This accelerates the rapid flow of cold or hot air in the first receiving cavity 11, thereby achieving rapid cooling or heating of the vehicle refrigerator, improving the cooling and heating performance and efficiency of the vehicle refrigerator, and providing passengers with a good user experience.

[0065] Optionally, the fan 31 can be installed inside or outside the drawer 60. The installation method should be selected according to the usage environment of the device, so as to improve the applicability and scope of application of the device.

[0066] Optionally, drawer 60 includes a first side plate 62, a second side plate 63, and a third side plate 64 connected sequentially and arranged at an angle. The first side plate 62 and the third side plate 64 are located on the same side of the second side plate 63. The second side plate 63 is arranged opposite to the fan 31, and a first ventilation hole 61 is provided on the second side plate 63. This arrangement allows the first ventilation hole 61 to be as close as possible to the air guide 32, thereby accelerating the airflow rate inside the drawer 60 and further improving the cooling and heating performance and efficiency of the vehicle refrigerator to meet the user's needs.

[0067] Optionally, a second ventilation hole 65 is provided on the first side plate 62 and / or the third side plate 64, and the second ventilation hole 65 communicates with the first receiving cavity 11. By providing the second ventilation hole 65, the air inside the drawer 60 and the air outside can circulate, thereby further accelerating the cooling and heating performance and efficiency of the drawer 60.

[0068] Optionally, the first ventilation hole 61 and / or the second ventilation hole 65 include at least one of polygonal holes, circular holes, and oblong holes. This configuration allows for customization based on actual usage, thereby improving the applicability and scope of the drawer 60. It not only ensures the aesthetic appearance of the drawer 60 but also enhances its usability.

[0069] Of course, the first ventilation hole 61 and / or the second ventilation hole 65 can also be configured as a triangular or trapezoidal structure, as long as it can meet the usage requirements of the device.

[0070] Optionally, the first ventilation hole 61 includes multiple first ventilation sub-holes 611. The area of ​​the first ventilation sub-hole 611 near the center of the second side panel 63 is smaller than the area of ​​the first ventilation sub-hole 611 near the edge of the second side panel 63, or the areas of the multiple first ventilation sub-holes 611 are the same. Compared to a single or a few first ventilation holes 61, multiple first ventilation holes 61 can form a more uniform airflow path, allowing air to circulate more smoothly within the drawer 60. This design helps reduce airflow resistance and improve airflow efficiency. Furthermore, the cross-sectional areas of the multiple first ventilation holes 61 can be the same or different according to actual usage requirements, thus further improving the applicability and scope of use of the drawer 60.

[0071] Optionally, a plurality of first ventilation sub-holes 611 are arranged in an array on the second side plate 63. The above arrangement is simple and easy to manufacture, which not only improves the manufacturing efficiency of the structure, but also meets the usage requirements of the device.

[0072] Optionally, the first ventilation hole 61 includes a plurality of first ventilation sub-holes 611, the plurality of first ventilation sub-holes 611 having the same shape or similar shapes. The above structure is simple, which not only facilitates the processing of the first ventilation hole 61, but also reduces the processing difficulty of the first ventilation hole 61, thereby improving the processing efficiency of the first ventilation hole 61 and facilitating the mass production of the drawer 60.

[0073] Optionally, the second ventilation hole includes multiple hole areas arranged sequentially on the first side panel and / or the third side panel. Each hole area includes multiple second ventilation sub-holes, with the area of ​​the second ventilation sub-holes near the center of the hole area being larger than the area of ​​the second ventilation sub-holes near the edge of the hole area, or the areas of the multiple second ventilation sub-holes being the same. Compared to a single or a few second ventilation holes 65, multiple second ventilation holes 65 can form a more uniform airflow path, allowing air to circulate more smoothly within the drawer 60. This design helps reduce airflow resistance and improve airflow efficiency. Furthermore, the cross-sectional areas of the multiple second ventilation holes 65 can be the same or different according to actual usage requirements, thus further improving the applicability and scope of use of the drawer 60.

[0074] Optionally, a plurality of second ventilation sub-holes 651 are arranged in an array on the first side plate 62 and / or the third side plate 64. The above arrangement is simple and easy to manufacture, which not only improves the manufacturing efficiency of the structure, but also meets the usage requirements of the device.

[0075] Optionally, the drawer 60 includes a plurality of second ventilation holes 651, which are identical in shape or similar in shape. This simple structure not only facilitates the processing of the second ventilation holes 651 but also reduces the processing difficulty, thereby improving the processing efficiency of the second ventilation holes 651 and enabling mass production of the drawer 60.

[0076] Optionally, the orthographic projection of the air inlet 311 or the air outlet 312 along the axis of the fan 31 is entirely located within the first ventilation hole 61. This arrangement allows the air from the air inlet 311 or the air outlet 312 to enter the drawer 60 as much as possible, thereby further improving the cooling and heating efficiency of the vehicle refrigerator.

[0077] Optionally, the housing includes a first inner liner 13, the first inner liner 13 having a first receiving cavity 11, and a drawer 60 movably disposed within the first receiving cavity 11. The first inner liner 13 of the vehicle refrigerator can effectively insulate against heat, preventing external heat or cold air from entering the refrigerator interior. It can also slow down the loss of heat or cold air inside the refrigerator, and maintain a stable temperature inside the drawer 60 under certain temperature conditions to meet the user's needs.

[0078] Optionally, the drawer 60 and the fan 31 are spaced apart, with the fan 31 located outside the drawer 60. By configuring the above structure, the air delivery effect of the fan 31 can be improved, thereby enhancing the cooling and heating performance of the vehicle refrigerator.

[0079] Optionally, the vehicle refrigerator also includes a refrigeration unit 70 for cooling the air in the first receiving cavity 11. This configuration meets the user's cooling needs, thereby improving the applicability of the vehicle refrigerator.

[0080] Optionally, the vehicle refrigerator also includes a heating element 80 for heating the air in the first receiving cavity 11. This configuration can meet the user's heating needs, thereby improving the applicability of the vehicle refrigerator.

[0081] Optionally, the refrigeration component 70 includes an evaporator, which is located on the side of the first inner liner 13 opposite to the drawer 60. The evaporator operates by utilizing the characteristic of refrigerant to absorb heat and vaporize at low pressure and low temperature. By absorbing external heat energy, the internal refrigerant boils and vaporizes, thereby lowering the surface temperature of the evaporator and achieving a cooling effect. The liquid refrigerant enters the evaporator after being throttled and depressurized through a throttling valve (such as an expansion valve). Due to the reduced pressure, the boiling point of the liquid refrigerant also decreases. At this time, the liquid refrigerant absorbs heat and evaporates in the evaporator, transforming into a gaseous state. During this process, the refrigerant absorbs heat from the surrounding medium, causing its temperature to drop, thus achieving cooling.

[0082] Optionally, the heating element 80 includes a heating film attached to the outer periphery of the evaporator. The heating film is a thin-film heating element, mainly composed of an electrically insulating material and a heating resistor material encapsulated within it. Heat is generated on the film by an electric current to achieve the heating function of the vehicle refrigerator. This simple structure not only reduces the production cost of the device but also meets the user's heating needs.

[0083] Optionally, a third opening 24 is provided on the outer wall of the second inner liner 23, which is used to communicate with the other end of the guide channel 321. In this application, the third opening 24 is located on the side of the second inner liner 23 away from the fan 31. Of course, the third opening 24 can also be located in other places of the second inner liner 23, as long as it meets the usage requirements of the device.

[0084] Optionally, the second housing 20 further includes a second inner liner 23, which has a second receiving cavity 21; the flow guide 32 is detachably connected to the second inner liner 23. With this configuration, when the first housing 10 and the second housing 20 are disassembled, the second housing 20 and the inner liner of the second inner liner 23 can be removed without disassembling the flow guide 32, thus enabling the conversion between the two refrigerators. This improves the disassembly efficiency of the second housing 20 and facilitates the assembly and disassembly of components.

[0085] Optionally, a heat insulation element is provided on the outer wall of the second inner liner 23. In this application, the heat insulation element is a vacuum heat insulation board, which is a type of vacuum insulation material. Because the interior of the vacuum heat insulation board is a near-vacuum environment, the vacuum layer does not conduct heat, thus having an extremely low thermal conductivity, typically less than 0.035 W / (m²·K), effectively preventing temperature loss within the second accommodating cavity 21. Simultaneously, its insulation effect is equivalent to 5 times that of traditional polystyrene boards, 4 times that of extruded polystyrene boards, and 2.8 times that of polyurethane. This makes the vacuum heat insulation board significantly superior to traditional insulation materials in terms of insulation performance.

[0086] Optionally, the vacuum insulation panel contains no OD (Oxide Discharge) materials, making it environmentally friendly and meeting the requirements of green ecology. Furthermore, the vacuum insulation panel is lightweight, weighing approximately 12 kg per square meter of wall, thus reducing the overall weight of the device and achieving lightweight design.

[0087] In addition, vacuum insulation panels have good thermal shock stability, high mechanical strength, high temperature and pressure resistance, long service life, and are not easy to fall off, thus providing higher safety performance.

[0088] Optionally, the vehicle refrigerator also includes a cover assembly 110, rotatably mounted on the second housing 20, which is used to open or close the second receiving cavity 21. This configuration allows the second receiving cavity 21 to be opened or closed, making it easier for the user to use and improving the ease of use of the device.

[0089] Optionally, the cover assembly 110 includes: an armrest cover 111, rotatably mounted on the second housing 20; and a door 112, fixedly connected to the armrest cover 111, the door 112 being used to open or close the second receiving cavity 21, the armrest cover 111 being located on the side of the door 112 away from the second receiving cavity 21.

[0090] Optionally, the cover includes: an armrest cover 111, rotatably connected to the second housing 20; and a door 112, rotatably connected to the second housing 20. The armrest cover 111 and the door 112 can rotate independently relative to the second housing 20. The armrest cover 111 is located on the side of the door 112 away from the second receiving cavity 21, and the door 112 is used to open or close the second receiving cavity 21. In the above structure, the armrest cover 111 and the door 112 are an integral structure. The door 112 and the armrest cover 111 are connected around their perimeter by positioning buckles and positioning posts. This allows the contents of the second receiving cavity 21 to be seen immediately upon opening the armrest cover 111, eliminating the need to open the armrest cover 111 and then the door 112 to retrieve items. This simplifies the structure of the vehicle refrigerator and increases the storage space of the second housing 20.

[0091] Optionally, a pull ring 113 is provided on the end face of the door body 112 near the armrest cover 111. The pull ring 113 is rotatably mounted on the door body 112 and is used to move the door body 112 from a position where the second receiving cavity 21 is closed to a position where the second receiving cavity 21 is open. In the above structure, the door body 112 and the armrest cover 111 are not integrated into one piece, but are separate structures. The door body 112 is set separately, that is, after opening the armrest cover 111, the door body 112 must also be opened to take out items. This can ensure the privacy of the objects in the second receiving cavity 21 and meet the user's usage needs.
