Description

Technical Field

[0001] This invention relates to the field of vehicle refrigerator technology, and in particular to a portable insulated box for vehicle refrigerators and a vehicle refrigerator. Background Technology

[0002] With the development of the vehicle industry and people's increasing demands for driving comfort, the application of in-vehicle refrigerators in the vehicle field is becoming increasingly widespread.

[0003] In order to optimize the interior space layout and improve the convenience of users accessing items, the current design trend is to integrate the car refrigerator into the center console of the vehicle, replacing the traditional center armrest box. This design allows both the driver and front passenger to easily access the refrigerated or warmed food and beverages in the car refrigerator, meeting the quality requirements of modern driving and travel.

[0004] However, when users need to take items out of the car refrigerator (such as for a picnic), they must take the items out one by one. This process is not only inconvenient, but more importantly, once the items are removed from the car refrigerator, their original insulation or cooling effect is immediately interrupted, causing the items to be unable to maintain a suitable temperature in the outdoor environment. In other words, the current technology cannot simultaneously meet the dual requirements of long-term insulation of items inside the car and insulation for carrying items outside the car, thus reducing the user experience. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the first objective of the present invention is to provide a portable insulated box for a car refrigerator, which can simultaneously meet the dual needs of long-term insulation of items inside the vehicle and insulation for carrying items outside the vehicle, and can also keep items cold and warm for a long time outside the vehicle, thereby improving the user experience.

[0006] A second objective of this invention is to provide a vehicle refrigerator having the aforementioned insulated box.

[0007] A portable insulated box for a vehicle refrigerator according to an embodiment of the present invention includes: a box body and a cover plate. The box body is adapted to be movably disposed in the receiving cavity of the vehicle refrigerator. A storage cavity with a top opening is formed in the box body. The cover plate is detachably installed at the opening of the storage cavity and is used to open or close the storage cavity. The box body and / or the cover plate include a heat insulation layer and a cold storage layer. The heat insulation layer and the cold storage layer are disposed opposite to each other in the thickness direction of the box body and / or the cover plate. The insulated box has a cold storage state and a cold release state. When the insulated box is placed in the receiving cavity of the vehicle refrigerator, the vehicle refrigerator cools down and simultaneously dissipates cold to the insulated box. At this time, the insulated box switches to the cold storage state, and the cold storage layer continuously stores cold. When the insulated box finishes storing cold and is removed from the vehicle refrigerator, the insulated box switches to the cold release state, and the cold storage layer continuously dissipates cold to the storage cavity.

[0008] According to an embodiment of the present invention, a portable insulated box for a car refrigerator is movably disposed within the receiving cavity of the car refrigerator. This allows the insulated box to not only be placed in the receiving cavity but also to be removed from it. This eliminates the need for users to individually remove items from the car refrigerator when taking them out of the vehicle (e.g., for a picnic), improving portability. Furthermore, by configuring the box body and / or cover to include an insulation layer and a cold storage layer, and by ensuring that the cold storage layer continuously stores cold when the box is in cold storage mode and continuously dissipates cold to the receiving cavity when the box is in cold release mode, the temperature inside the receiving cavity can be maintained at the temperature required for cooling and insulation of the items for an extended period. This enhances the cooling effect when the box is removed from the car refrigerator, allowing items to maintain a suitable temperature even in outdoor environments, thereby improving the user experience.

[0009] In some embodiments, the insulation layer includes a first shell and an insulation medium, wherein an insulation space is formed within the first shell, and the insulation medium is filled within the insulation space.

[0010] In some embodiments, the cold storage layer includes a second shell and a cold storage agent, wherein a cold storage space is formed within the second shell, and the cold storage agent is filled into the cold storage space.

[0011] In some embodiments, the housing includes a bottom plate and a plurality of side plates, the plurality of side plates being disposed on top of the bottom plate and sequentially connected along the circumference of the bottom plate, the plurality of side plates and the bottom plate cooperating to define the holding cavity.

[0012] In some embodiments, the insulated box is configured such that, in the cold storage state, the cold storage layer directly exchanges heat with the refrigeration system of the vehicle refrigerator.

[0013] In some embodiments, the enclosure further includes a door, and the bottom plate and / or the side plate are provided with a through mounting opening. The door is rotatably mounted to the mounting opening via a pivot. The insulated box is configured to control the rotation of the door to enable the cold storage layer to directly exchange heat with the refrigeration system of the vehicle refrigerator.

[0014] In some embodiments, the pivot is located near the end of the door in the length or width direction of the door body, so that the door body can be rotated at a certain angle relative to the bottom plate and / or the side plate, thereby opening the mounting port. The refrigeration system of the vehicle refrigerator is adapted to transfer cold energy directly to the cold storage layer through the mounting port.

[0015] In some embodiments, the door body includes the heat insulation layer and the cold storage layer disposed opposite to each other. The pivot is located in the middle of the door body in the length or width direction, so that the door body can rotate 360° relative to the bottom plate and / or the side plate, thereby allowing the cold storage layer inside the door body to directly contact the refrigeration system of the vehicle refrigerator.

[0016] In some embodiments, the pivot is a damped pivot, so that the door can be suspended at any position within the rotation range.

[0017] In some embodiments, the insulated box further includes a first sealing element, which is disposed on the inner peripheral wall of the mounting port and / or on the outer periphery of the door body to achieve a sealing fit between the door body and the mounting port.

[0018] In some embodiments, the insulation box further includes a thermometer disposed on the surface of the cold storage layer, the thermometer being used to detect the temperature of the cold storage layer.

[0019] In some embodiments, the cover plate is a transparent cover plate.

[0020] In some embodiments, the insulated box further includes a second seal disposed between the box body and the cover plate.

[0021] In some embodiments, the insulated box further includes a first handle and / or a second handle, the first handle being rotatably connected to the top of the box body and the second handle being connected to the top of the cover plate.

[0022] According to an embodiment of the present invention, a vehicle refrigerator includes: a main body having a receiving cavity with a top opening; and a heat preservation box, wherein the heat preservation box is the aforementioned heat preservation box, and the heat preservation box is movably disposed within the receiving cavity through the opening of the receiving cavity.

[0023] According to the embodiments of the present invention, the in-vehicle refrigerator, by adopting the aforementioned insulated box, on the one hand, allows users to take items out of the in-vehicle refrigerator without having to take the items out of the refrigerator one by one when they need to take them out of the vehicle (such as for a picnic), thus improving the portability of the items; on the other hand, it allows the items to continue to maintain a suitable temperature in the outdoor environment after leaving the in-vehicle refrigerator, thereby improving the user experience.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0029] The portable insulated box 100 for a vehicle refrigerator 1000 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0030] Combination Figure 1 , Figure 2 and Figure 3 As shown, the portable insulated box 100 for the vehicle refrigerator 1000 according to an embodiment of the present invention includes: a box body 110 and a cover plate 120.

[0031] Among them, combined Figure 1 , Figure 2 and Figure 3 As shown, the cabinet 110 is adapted to be movably disposed in the receiving cavity 210 of the vehicle refrigerator 1000. A storage cavity 111 with a top opening is formed inside the cabinet 110. A cover plate 120 is detachably installed at the opening of the storage cavity 111. The cover plate 120 is used to open or close the storage cavity 111.

[0032] It should be noted that the box body 110 is suitable for being movably installed in the receiving cavity 210 of the car refrigerator 1000. This means that the box body 110 of the insulated box 100 is not fixed relative to the receiving cavity 210 of the car refrigerator 1000, but can be moved and removed. Simply put, there is an insulated box 100 that can be flexibly taken in and out in the receiving cavity 210 of the car refrigerator 1000, which makes it easier for users to classify, store or retrieve items more freely. In this way, when users need to take the items in the car refrigerator 1000 out of the car (such as for a picnic), they do not need to take the items out of the car refrigerator 1000 one by one, which improves the portability of the items and enhances the user experience.

[0033] Meanwhile, by providing a top-opening storage cavity 111 inside the body 110 of the insulated box 100, and detachably installing a cover plate 120 at the opening of the storage cavity 111, the storage cavity 111 can be in both a closed and open state. When the storage cavity 111 is in the closed state, it is convenient to protect the items inside the storage cavity 111. When the storage cavity 111 is in the open state, it is convenient for the user to take out the items inside the storage cavity 111, and it is also convenient to clean the storage cavity 111.

[0034] In some embodiments, the cover plate 120 can be rotatably connected to the opening of the container cavity 111 via a rotating shaft, or the cover plate 120 can be snapped into the opening of the container cavity 111 via a snap-fit ​​structure, so that the cover plate 120 can open or close the container cavity 111.

[0035] Combination Figure 3 , Figure 4 and Figure 5 As shown, the enclosure 110 and / or cover 120 include an insulation layer 130 and a cold storage layer 140, which are disposed opposite to each other in the thickness direction of the enclosure 110 and / or cover 120. This means that the enclosure 110 includes the insulation layer 130 and the cold storage layer 140; or, the cover 120 includes the insulation layer 130 and the cold storage layer 140; or, both the enclosure 110 and the cover 120 include the insulation layer 130 and the cold storage layer 140.

[0036] When the insulated box 100 is used in an outdoor environment away from the vehicle refrigerator 1000, the core function of the insulation layer 130 is to prevent heat exchange between the inside and outside of the insulated box 100, reduce the impact of the external ambient temperature on the inside of the insulated box 100, and at the same time retain the existing cold energy inside the insulated box 100 to maintain the stability of the temperature inside the insulated box 100; the core function of the cold storage layer 140 is to store cold energy in advance and release it slowly when needed, actively replenishing the cold energy inside the insulated box 100, offsetting the small amount of external heat that seeps in, and is the core cold source for maintaining the low temperature inside the insulated box 100.

[0037] Therefore, by configuring the box body 110 and / or cover plate 120 to simultaneously include an insulation layer 130 and a cold storage layer 140, on the one hand, the insulation layer 130 can reduce the loss of cold energy in the storage cavity 111 and reduce the release pressure of the cold storage layer 140. On the other hand, the cold storage layer 140 can actively release cold to offset a small amount of heat that seeps in and replenish the cold energy. The combination of the two enables the insulated box 100 to maintain a low temperature for a long time with high precision and without power, thereby improving the cooling effect of the insulated box 100 when it is removed from the vehicle refrigerator 1000. This allows items to continue to maintain a suitable temperature in the outdoor environment after being removed from the vehicle refrigerator 1000, thereby improving the user experience.

[0038] The insulated box 100 has a cold storage state and a cold release state. When the insulated box 100 is placed in the receiving cavity 210 of the vehicle refrigerator 1000, the vehicle refrigerator 1000 cools down and simultaneously dissipates cold to the insulated box 100. At this time, the insulated box 100 switches to the cold storage state, and the cold storage layer 140 continues to store cold. When the insulated box 100 finishes storing cold and is removed from the vehicle refrigerator 1000, the insulated box 100 switches to the cold release state, and the cold storage layer 140 continues to dissipate cold to the holding cavity 111.

[0039] In other words, when the insulated box 100 is placed in the receiving cavity 210 of the vehicle refrigerator 1000, the cold storage layer 140 stores cold energy, so that the cold storage layer 140 can form a mobile cold source. When the insulated box 100 finishes storing cold energy and is removed from the vehicle refrigerator 1000, the cold storage layer 140 can slowly release the stored cold energy according to the temperature change in the holding cavity 111. In this way, when a small amount of external heat seeps into the holding cavity 111, the cold release process of the cold storage layer 140 can quickly neutralize the heat, prevent the temperature in the holding cavity 111 from rising, maintain the low temperature in the holding cavity 111, and improve the cooling effect of the insulated box 100 when it is removed from the vehicle refrigerator 1000. This allows the items to continue to maintain a suitable temperature in the outdoor environment after being removed from the vehicle refrigerator 1000, thereby improving the user experience.

[0040] As can be seen from the above structure, the portable insulated box 100 for the car refrigerator 1000 of this embodiment can not only be placed in the receiving cavity 210 of the car refrigerator 1000, but also be taken out from the receiving cavity 210 of the car refrigerator 1000. In this way, when the user needs to take the items in the car refrigerator 1000 out of the car (such as for a picnic), there is no need to take the items out of the car refrigerator 1000 one by one, which improves the portability of the items.

[0041] Meanwhile, the enclosure 110 and / or cover 120 are configured to include both an insulation layer 130 and a cold storage layer 140. The insulation layer 130 reduces heat loss by insulating the enclosure, while the cold storage layer 140 actively releases cold to offset the small amount of heat that seeps in and replenishes the cold energy. The combination of these two features enables the insulated box 100 to maintain a low temperature for a long time with high precision and without power, thereby improving the cooling effect of the insulated box 100 when it is removed from the vehicle refrigerator 1000.

[0042] In summary, the portable insulated box 100 used with the vehicle refrigerator 1000 of this application not only improves the portability of items, but also ensures that items leaving the vehicle refrigerator 1000 can be kept cold.

[0043] In specific examples, combined Figure 3 , Figure 4 and Figure 5 As shown, the box 110 includes an insulation layer 130 and a cold storage layer 140, and the cover plate 120 includes an insulation layer 130. This not only allows the insulation layer 130 and the cold storage layer 140 to be combined to achieve long-term, high-precision, and unpowered low-temperature maintenance of the insulated box 100, but also simplifies the structure of the cover plate 120, thereby reducing the molding difficulty of the cover plate 120.

[0044] In some embodiments, combined with Figure 3 , Figure 4 and Figure 5 As shown, the box 110 includes an insulation layer 130 and a cold storage layer 140. In the thickness direction of the box 110, the insulation layer 130 and the cold storage layer 140 are arranged opposite to each other. When the insulated box 100 finishes cold storage and is removed from the vehicle refrigerator 1000, the cold storage layer 140 is located on the side of the insulation layer 130 facing the container cavity 111. The insulation layer 130 can prevent the cold storage layer 140 from releasing cold energy to the outside of the container cavity 111, so that the cold energy released by the cold storage layer 140 can effectively act on the container cavity 111, thereby maintaining the low temperature inside the container cavity 111.

[0045] In some embodiments, combined with Figure 3 , Figure 4 and Figure 5As shown, the insulation layer 130 includes a first shell 131 and an insulation medium 132. An insulation space is formed inside the first shell 131, and the insulation medium 132 is filled into the insulation space. The insulation medium 132 is used to ensure the performance of the insulation layer 130, so that the insulation layer 130 can, to a certain extent, prevent the heat exchange between the cold air inside the insulation box 100 and the heat outside, slow down the rate of temperature rise inside the insulation box 100, and facilitate providing a low-temperature environment for the items inside the insulation box 100 for a long time.

[0046] Meanwhile, by filling the insulation medium 132 into the insulation space, the insulation medium 132 is filled into the first shell 131. This not only enables the first shell 131 to support the insulation medium 132 and improve the positional stability of the insulation medium 132, but also enables the first shell 131 to protect the insulation medium 132, thereby extending the service life of the insulation medium 132 and avoiding frequent replacement of the insulation medium 132, thus reducing the usage cost of the insulation layer 130.

[0047] It should be noted that filling the insulation medium 132 into the insulation space can be understood as: injecting the insulation medium 132 into the interior of the insulation space through a certain process and filling it with the entire insulation space, so as to improve the insulation effect of the insulation layer 130 by using the insulation medium 132.

[0048] In some embodiments, the insulation medium 132 is foam, which is filled in the insulation space to ensure the insulation performance of the insulation layer 130.

[0049] Of course, in other embodiments, the insulation medium 132 may be other insulation components, and no specific limitation is made here.

[0050] In some embodiments, the first housing 131 may be made of materials such as polyurethane or polystyrene, so that the first housing 131 itself also has excellent thermal insulation performance, thereby maximizing the thermal insulation performance of the insulation layer 130.

[0051] In some embodiments, the insulation layer 130 may also be an integral insulation structure.

[0052] In some embodiments, combined with Figure 3 , Figure 4 and Figure 5 As shown, the cold storage layer 140 includes a second shell 141 and a cold storage agent 142. A cold storage space is formed inside the second shell 141, and the cold storage agent 142 is filled into the cold storage space. The cold storage agent 142 is used to ensure the cold storage effect of the cold storage layer 140, so that the cold storage layer 140 can effectively maintain the low temperature inside the insulated box 100 placed outside the vehicle refrigerator 1000, delay the temperature rise inside the insulated box 100, and thus extend the preservation time of the items.

[0053] Meanwhile, by filling the cold storage space with the cold storage agent 142, the cold storage agent 142 is filled into the second shell 141. This not only allows the second shell 141 to support the cold storage agent 142 and improve the positional stability of the cold storage agent 142, but also allows the second shell 141 to protect the cold storage agent 142, thereby extending the service life of the cold storage agent 142 and avoiding frequent replacement of the cold storage agent 142, thus reducing the cost of using the cold storage agent 142.

[0054] It should be noted that the filling of the cold storage space with the cold storage agent 142 can be understood as: injecting the cold storage agent 142 into the entire interior of the cold storage space through certain process means, so as to ensure the cold storage effect of the cold storage layer 140.

[0055] In some embodiments, the cold storage medium of the cold storage agent 142 is at least one of paraffin, polyol, hydrated salt and eutectic solution to ensure the thermal insulation performance of the cold storage layer 140.

[0056] In some embodiments, the cold storage agent 142 is a gel-like cold storage agent, which is formed by combining a cold storage medium with a polyvinyl alcohol-borax crosslinking system. Compared with traditional liquid cold storage agents, the gel-like cold storage agent can reduce the risk of leakage of the cold storage agent 142, and can store more cold energy in the same volume, maintaining the low temperature for a longer time, which is convenient for providing a low temperature environment for items in the insulation box 100 for a long time.

[0057] In some embodiments, the second housing 141 may be made of metal materials (such as stainless steel) or engineering plastics (such as high-density polyethylene, polypropylene) to give the second housing 141 excellent thermal conductivity, which allows the refrigerant 142 inside the second housing 141 to absorb and release cold energy more quickly, thereby improving the overall performance of the cold storage layer 140.

[0058] In the description of this invention, features defined as "first" and "second" may explicitly or implicitly include one or more of the features, used to distinguish and describe features, without any order or importance.

[0059] In some embodiments, combined with Figure 3 , Figure 4 and Figure 5 As shown, the box 110 includes a bottom plate 112 and multiple side plates 113. The multiple side plates 113 are disposed on the top of the bottom plate 112 and connected sequentially along the circumference of the bottom plate 112. The multiple side plates 113 and the bottom plate 112 cooperate to define a storage cavity 111. This reduces the molding difficulty of the storage cavity 111, thereby facilitating the storage of items using the box 110.

[0060] It should be noted that the connection between the side plate 113 and the base plate 112 mentioned here can be welding, bonding, snap-fitting, or integral molding, etc.

[0061] In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0062] In some embodiments, the insulated box 100 is configured such that, in a cold storage state, the cold storage layer 140 directly exchanges heat with the refrigeration system of the vehicle refrigerator 1000. That is, when the insulated box 100 is placed in the receiving cavity 210 of the vehicle refrigerator 1000, the cold storage layer 140 is controlled to directly exchange heat with the refrigeration system of the vehicle refrigerator 1000, thereby improving the heat exchange efficiency between the cold storage layer 140 and the refrigeration system of the vehicle refrigerator 1000, thus increasing the cold storage speed and cold storage capacity of the cold storage layer 140. This allows the cold storage layer 140 to release cold energy into the holding cavity 111 when the insulated box 100 is removed from the vehicle refrigerator 1000, preventing the temperature inside the holding cavity 111 from rising, maintaining a low temperature, and improving the cooling effect of the insulated box 100 when it is removed from the vehicle refrigerator 1000.

[0063] In some embodiments, combined with Figures 3-7 As shown, the enclosure 110 also includes a door 114, and a mounting opening 115 is provided on the bottom plate 112 and / or side plate 113. The door 114 is rotatably mounted to the mounting opening 115 via a pivot 191. The insulated box 100 is configured to control the rotation of the door 114 to achieve direct heat exchange between the cold storage layer 140 and the refrigeration system of the vehicle refrigerator 1000. In other words, the insulated box 100 of this application can achieve direct heat exchange between the cold storage layer 140 and the refrigeration system of the vehicle refrigerator 1000 by controlling the rotation of the door 114, reducing the difficulty of direct heat exchange between the cold storage layer 140 and the refrigeration system of the vehicle refrigerator 1000, thereby improving the cold storage speed and cold storage capacity of the cold storage layer 140.

[0064] In some embodiments, a drive unit may be provided to enable the door body 114 to rotate using the drive unit, or to directly drive the door body 114 to rotate manually.

[0065] It should be noted that the mounting opening 115 through the base plate 112 and / or the side plate 113 means that the base plate 112 has a mounting opening 115 through it; or, the side plate 113 has a mounting opening 115 through it; or, both the base plate 112 and the side plate 113 have mounting openings 115 through them.

[0066] In specific examples, combined Figure 3 , Figure 4 and Figure 5As shown, the side panel 113 is provided with a through mounting opening 115. The door body 114 is rotatably mounted to the mounting opening 115 via a pivot 191, so that the door body 114 can be rotatably mounted on the side panel 113 via the pivot 191. Compared with mounting the door body 114 on the base plate 112, this reduces the difficulty of opening and closing the door body 114.

[0067] In some embodiments, combined with Figure 5 , Figure 6 and Figure 7 As shown, a pivot 191 is provided near the end of the door 114 in the length or width direction of the door body 114, so that the door body 114 can be rotated at a certain angle relative to the bottom plate 112 and / or the side plate 113, thereby opening the mounting port 115. The refrigeration system of the vehicle refrigerator 1000 is adapted to transfer cold energy directly to the cold storage layer 140 through the mounting port 115. This refers to the following: when the door 114 is rotatably mounted to the mounting port 115 on the base plate 112 via the pivot 191, the pivot 191 is positioned close to the end of the door 114 so that the door 114 can rotate at a certain angle relative to the base plate 112; when the door 114 is rotatably mounted to the mounting port 115 on the side plate 113 via the pivot 191, the pivot 191 is positioned close to the end of the door 114 so that the door 114 can rotate at a certain angle relative to the side plate 113. After the door 114 rotates at a certain angle, the mounting port 115 can be opened, so that the refrigeration system of the vehicle refrigerator 1000 can directly transfer cold energy to the cold storage layer 140 through the mounting port 115, so that the cold storage layer 140 can directly exchange heat with the refrigeration system of the vehicle refrigerator 1000, thereby improving the cold storage speed and cold storage capacity of the cold storage layer 140.

[0068] It should be noted that when the insulated box 100 finishes storing cold and is removed from the vehicle refrigerator 1000, the door 114 remains closed at the mounting port 115 to prevent the cold energy in the storage cavity 111 from dissipating through the mounting port 115, thus maintaining the low temperature in the storage cavity 111. When the insulated box 100 is placed in the receiving cavity 210 of the vehicle refrigerator 1000, the door 114 can be rotated at a certain angle relative to the bottom plate 112 and / or the side plate 113 before the insulated box 100 is placed in the receiving cavity 210 of the vehicle refrigerator 1000, thereby opening the mounting port 115. In this way, after the insulated box 100 is placed in the receiving cavity 210 of the vehicle refrigerator 1000, the refrigeration system of the vehicle refrigerator 1000 can directly transfer cold energy to the cold storage layer 140 through the mounting port 115, thereby improving the cold storage speed and cold storage capacity of the cold storage layer 140.

[0069] In some embodiments, combined with Figures 9-15As shown, the door body 114 includes an insulation layer 130 and a cold storage layer 140 disposed opposite to each other. In the length or width direction of the door body 114, a pivot 191 is provided in the middle of the door body 114 so that the door body 114 can rotate 360° relative to the bottom plate 112 and / or the side plate 113, so that the cold storage layer 140 on the inside of the door body 114 can directly contact the refrigeration system of the vehicle refrigerator 1000. In other words, the pivot 191 is not limited to being located near the end of the door 114, but can also be located in the middle of the door 114. In this way, when the door 114 is rotated, it can rotate 360° relative to the bottom plate 112 and / or the side plate 113, so that the cold storage layer 140 inside the door 114 can directly contact the refrigeration system of the vehicle refrigerator 1000. This also allows the cold storage layer 140 to directly exchange heat with the refrigeration system of the vehicle refrigerator 1000, thereby improving the cold storage speed and cold storage capacity of the cold storage layer 140.

[0070] It should be noted that the door body 114 rotating 360° relative to the base plate 112 and / or the side plate 113 means that when the door body 114 is rotatably mounted to the mounting opening 115 on the base plate 112 via the pivot 191, the pivot 191 is located in the middle of the door body 114 so that the door body 114 can rotate 360° relative to the base plate 112; when the door body 114 is rotatably mounted to the mounting opening 115 on the side plate 113 via the pivot 191, the pivot 191 is located in the middle of the door body 114 so that the door body 114 can rotate 360° relative to the side plate 113.

[0071] Simultaneously, when the insulated box 100 finishes storing cold and detaches from the vehicle refrigerator 1000, the door 114 is rotated so that the cold storage layer 140 on the door 114 is positioned directly opposite the container cavity 111, thereby enabling the cold storage layer 140 to effectively release cold energy into the container cavity 111 and maintain the low temperature inside the container cavity 111; when the insulated box 100 is placed in the container cavity 210 of the vehicle refrigerator 1000, the insulated box 100 can be placed in the container cavity 210 of the vehicle refrigerator 1000. Previously, the control door 114 was rotated 360° relative to the base plate 112 and / or the side plate 113. This way, when the insulated box 100 was placed in the receiving cavity 210 of the vehicle refrigerator 1000, the cold storage layer 140 inside the door 114 could directly contact the refrigeration system of the vehicle refrigerator 1000, so that the refrigeration system of the vehicle refrigerator 1000 could directly transfer cold energy to the cold storage layer 140 through the mounting port 115, thereby improving the cold storage speed and cold storage capacity of the cold storage layer 140.

[0072] In some embodiments, combined with Figure 6 , Figure 7 , Figure 14 and Figure 15As shown, there are two pivots 191, which are spaced apart on opposite sides of the door body 114. The cooperation of the two pivots 191 helps to improve the stability of the door body 114 when rotating, and also avoids jamming when the door body 114 rotates, thus improving the smoothness of the door body 114 rotation.

[0073] In some embodiments, the pivot 191 is a damped pivot, allowing the door 114 to be suspended at any position within its rotation range. This achieves the function of fixing the door 114, so that when the door 114 is rotated at a certain angle relative to the base plate 112 and / or the side plate 113, the door 114 can effectively and continuously open the mounting port 115, allowing the refrigeration system of the vehicle refrigerator 1000 to effectively transfer cold energy directly to the cold storage layer 140 through the mounting port 115. At the same time, when the door 114 is rotated 360° relative to the base plate 112 and / or the side plate 113, the cold storage layer 140 inside the door 114 can effectively and continuously contact the refrigeration system of the vehicle refrigerator 1000, thereby enabling the cold storage layer 140 to directly exchange heat with the refrigeration system of the vehicle refrigerator 1000, thereby improving the cold storage speed and cold storage capacity of the cold storage layer 140.

[0074] Meanwhile, by setting a damping pivot, it is possible to avoid setting a locking device to control the suspension of the door 114, which means eliminating the need for a locking device and simplifying the structure of the insulation box 100. Furthermore, the damping pivot ensures that the rotation of the door 114 is always subject to controllable resistance, achieving a uniform and smooth opening and closing action, and preventing the door 114 from impacting the side plate 113 or the bottom plate 112.

[0075] In some embodiments, combined with Figure 4 , Figure 5 , Figure 12 and Figure 13 As shown, there are two doors 114, each mounted on a different side panel 113 and positioned opposite each other. When the refrigeration system of the vehicle refrigerator 1000 directly transfers cold energy to the cold storage layer 140 through the mounting port 115, the two oppositely positioned doors 114 facilitate simultaneous transfer of cold energy from the refrigeration system to the cold storage layer 140 through both mounting ports 115, thereby improving the cold storage efficiency of the cold storage layer 140.

[0076] Meanwhile, when the cold storage layer 140 inside the door 114 is in direct contact with the refrigeration system of the vehicle refrigerator 1000, by setting two oppositely arranged doors 114, the contact area between the cold storage layer 140 and the refrigeration system can be increased, and the cold storage efficiency can also be improved.

[0077] Of course, in other embodiments, the gate 114 may include one, three, four or more, and no specific limitation is made here.

[0078] In some embodiments, combined with Figure 5 , Figure 8 , Figure 14 and Figure 16 As shown, the insulated box 100 also includes a first sealing element 150, which is disposed on the inner peripheral wall of the mounting port 115 and / or on the outer periphery of the door 114 to achieve a sealing fit between the door 114 and the mounting port 115. This prevents the cold air inside the insulated box 100 from leaking through the gap between the door 114 and the mounting port 115 and prevents the heat outside the insulated box 100 from entering the container cavity 111 through the gap between the door 114 and the mounting port 115, thereby slowing down the rate of temperature rise inside the insulated box 100. This allows the insulated box 100 to maintain a low temperature for a long time with high precision and without power, improving the cooling effect of the insulated box 100 when it is removed from the vehicle refrigerator 1000.

[0079] In some embodiments, the first sealing element 150 is a first sealing ring, which surrounds the outer periphery of the door body 114. This not only reduces the assembly difficulty of the first sealing ring, but also facilitates the sealing fit between the door body 114 and the mounting port 115 using the first sealing ring.

[0080] Of course, in some other embodiments, the first sealing ring may also be provided on the inner peripheral wall of the mounting port 115.

[0081] In some embodiments, such as Figure 6 , Figure 11 and Figure 12 As shown, the insulated box 100 also includes a thermometer 160, which is disposed on the surface of the cold storage layer 140 and is used to detect the temperature of the cold storage layer 140. This allows the user to clearly know the current temperature of the insulated box 100, thus facilitating the user's decision on whether the insulated box 100 can be removed from the vehicle refrigerator 1000 for use. Simultaneously, when the insulated box 100 is detached from the vehicle refrigerator 1000 for outdoor use, it allows the user to determine whether the items inside the insulated box 100 need to be disposed of promptly and whether the insulated box 100 needs to be returned to the vehicle refrigerator 1000 for cold storage, improving the controllability of the insulated box 100 during use.

[0082] Meanwhile, by using a thermometer 160 to detect the temperature of the cold storage layer 140, temperature detection is simpler and easier to implement compared to using a temperature sensor.

[0083] In some embodiments, the thermometer 160 can be attached to the surface of the cold storage layer 140 by means of adhesive bonding, so as to detect the temperature of the cold storage layer 140 by means of the thermometer 160, while ensuring the positional stability of the thermometer 160.

[0084] Of course, in some other embodiments, a temperature sensor can also be provided and placed on the surface of the cold storage layer 140 to detect the temperature of the cold storage layer 140.

[0085] In some embodiments, the cover 120 is a transparent cover. This allows the user to observe the value of the thermometer 160 through the cover 120, thereby enabling the user to intuitively understand the current temperature of the incubator 100.

[0086] In some embodiments, the cover plate 120 is a glass plate, such that the cover plate 120 is formed as a transparent cover plate.

[0087] In some embodiments, such as Figure 5 As shown, the insulated box 100 also includes a second sealing element 170, which is disposed between the box body 110 and the cover plate 120. This is to prevent the cold air inside the insulated box 100 from leaking through the gap between the box body 110 and the cover plate 120, and to prevent the heat outside the insulated box 100 from entering the container cavity 111 through the gap between the box body 110 and the cover plate 120, thereby further slowing down the rate of temperature rise inside the insulated box 100. This allows the insulated box 100 to maintain a low temperature for a long time with high precision and without power, improving the cooling effect of the insulated box 100 when it is removed from the vehicle refrigerator 1000.

[0088] In some embodiments, the second sealing element 170 is a second sealing ring, which is disposed on the housing 110 or the cover plate 120 to facilitate the sealing fit between the housing 110 and the cover plate 120 by means of the second sealing ring.

[0089] In some embodiments, such as Figure 11 As shown, the insulated box 100 also includes a first handle 180 and / or a second handle 190. The first handle 180 is rotatably connected to the top of the box body 110, and the second handle 190 is connected to the top of the cover plate 120. This means that the insulated box 100 includes the first handle 180; or, the insulated box 100 includes the second handle 190; or, the insulated box 100 includes both the first handle 180 and the second handle 190. When the insulated box 100 includes the first handle 180, the first handle 180 is rotatably connected to the top of the box body 110 to facilitate removing the insulated box 100 from the receiving cavity 210 of the vehicle refrigerator 1000 via the first handle 180, and also to facilitate placing the insulated box 100 into the receiving cavity 210 of the vehicle refrigerator 1000 via the first handle 180, thereby reducing the difficulty of taking the insulated box 100 out of the vehicle refrigerator 1000.

[0090] Meanwhile, when the insulated box 100 includes a second handle 190, it facilitates the installation of the cover 120 at the opening of the container cavity 111 via the second handle 190, and also facilitates the removal of the cover 120 from the opening of the container cavity 111 via the second handle 190, thereby reducing the difficulty of opening and closing the container cavity 111 with the cover 120.

[0091] In addition, by rotatably connecting the first handle 180 to the top of the box 110, the first handle 180 is prevented from obstructing the movement of the cover 120, further reducing the difficulty of opening and closing the cover 120 to the container cavity 111.

[0092] The following description of an embodiment of the vehicle refrigerator 1000 of the present invention is based on the accompanying drawings.

The specific structure of the insulated box 100 will not be described in detail here. The insulated box 100 is movably disposed in the receiving cavity 210 through the opening of the receiving cavity 210.

[0095] As can be seen from the above structure, the vehicle refrigerator 1000 of the present invention, by adopting the aforementioned insulated box 100, on the one hand, enables users to take items out of the vehicle refrigerator 1000 one by one when they need to take the items out of the vehicle refrigerator 1000 (such as for a picnic), thus improving the portability of the items. On the other hand, it enables the items to continue to maintain a suitable temperature in the outdoor environment after leaving the vehicle refrigerator 1000, thereby improving the user experience.
