Description

Technical Field

[0001] An embodiment of the present invention relates to a container, particularly an insulated box. Background Art

[0002] Existing insulated containers are generally made of EPS or EPP foaming materials. Such materials have good toughness but poor rigidity. When using, after placing goods in the container, the lid is covered on the box body and then the goods are delivered. For such insulated boxes, the general external dimensions are 600*400*300mm and the internal volume is about 45 liters. Such insulated containers are mainly used for fresh food delivery. After sorting pre-cooled fresh food or frozen products in a cold storage, they are loaded into the insulated box together with cold storage plates and then delivered to households. Such an insulated container is a single box body. Since the heat preservation performance of the insulated container depends on the adiabatic coefficient of the material itself and the thickness of the box body, and the box body often needs to consider the usable volume, when the adiabatic coefficient is certain, the thickness of the box body is relatively fixed, and finally the heat preservation performance is poor. The external environmental temperature of the insulated container causes the temperature inside the insulated container to drop slowly due to the consumption of cold energy, and the heat preservation time limit is also short. The temperature inside the insulated box cannot be reduced to a very low temperature, so it cannot meet the needs of objects that need to be stored at a very low temperature. In addition, the short heat preservation time limit and poor heat preservation performance also result in the inability to store and transport objects for a long time, and the use is relatively limited.

[0073] As used in this specification and the appended claims, the singular forms "a" and "the" include plural referents unless the context clearly dictates otherwise. It should be noted that the term "or" is generally used in its inclusive sense of "and / or" unless the context clearly dictates otherwise.

[0074] In the following description, in order to clearly show the structure and working mode of the present invention, many directional terms will be used for description. However, terms such as "front", "rear", "left", "right", "outer", "inner", "outward", "inward", "up", "down", etc. should be understood as convenient terms and should not be construed as limiting terms.

[0075] The embodiments of the present invention are described below with reference to the accompanying drawings. As Figure 1 , Figure 2 , Figure 3 andFigure 4 As shown in the figure, the incubator 900 includes an inner box 100 and an outer box 9 that houses the inner box 100. The inner box 100 has an inner box body 20 with a first opening, a first lid 4 that operably covers the first opening, and a first cold storage member 42 disposed inside the inner box. The inner box body 20 has a first base 1 and two pairs of opposite first side plates 2 and 3 that are foldably connected to the first base 1. The outer box 9 has an outer box body 90 with a second opening 9030 and a second lid 904 that operably covers the second opening 9030. The outer box body 90 has a second base 901 and two pairs of opposite second side plates 902 and 903 that are foldably connected to the second base 901. At each longitudinal end of the first side plates 2 and 3, there are engaging portions 202 and 302. When each side plate is erected relative to the first base 1, the first side plates 2 and 3 are connected to each other by engaging the engaging portions 202 and 302, thereby jointly forming the internal volume of the inner box 100 with the first base 1. The first lid 4 can cover the first opening 30 of the inner box 100. In order to save transportation and storage space, as Figure 4 、 Figure 5 and Figure 6 shown, the inner box 100 and the outer box 90 are separated and folded for transportation and storage respectively.

[0076] As can be seen from the above, the inner box 100 is nested inside the outer box 9. The outer box 9 places the inner box 100 in a more enclosed environment, reducing the influence of the external temperature on the temperature inside the inner box 100, improving the long-term heat preservation effect of the inner box 100, making the heat preservation effect of the inner box 100 better. Thus, the temperature inside the inner box can be reduced to a lower temperature, objects that require a lower temperature can be placed, and the time for storing and transporting objects in the incubator 900 can be extended, ensuring the quality of the objects inside the incubator and also giving the incubator a wider range of uses. In addition, the inner box body 100 can be folded, and the outer box body 9 can also be folded. Therefore, when simply transporting and storing the incubator 900, the space occupied by the incubator 900 is reduced, saving transportation costs.

[0077] The structure of the outer box 9 refers to the Chinese patent application with the invention name "Foldable Container" and the publication number CN111453133A. The full text of the above application is incorporated herein by reference.

[0078] There is a second cold storage member inside the outer box body 90. The second cold storage member is disposed on the side of the second lid 904 facing the inside of the outer box body 90. The second cold storage member can be fixed to the second lid 904 through a fixing plate or directly locked to the lid through bolts. The second cold storage member can also be disposed on the second base 901 or on the second side plates 902 and 903.

[0079] Such as Figure 2 、 Figure 3As shown, the second side plate 902 is disposed opposite to the first side plate 2, and the second side plate 903 is disposed opposite to the first side plate 3. The second side plate 902 covers the docking area between the first side plate 2 and the first base 1, and the second side plate 903 covers the docking area between the first side plate 3 and the first base 1. Specifically, the height of the first base 1 is higher than that of the second base 901, so that the upper edge of the first base 1 is higher than the upper edge of the second base 901, thereby better preventing the influence of the external temperature on the temperature inside the inner box 100.

[0080] At least one second side plate covers the docking areas of two adjacent first side plates. The first side plate 2 and the first side plate 3 are engaged and connected, and the first side plate 903 covers the engaged area between the first side plate 2 and the first side plate 3, further reducing the influence of the external temperature on the temperature inside the inner box 100.

[0081] Specifically, both the second side plates 903 and 902 are straight plates. The first side plate 2 has a bent portion 23 that bends toward the adjacent first side plate 3. There is an engaging portion 202 on the bent portion 23, and there is an engaging portion 301 on the side plate 3. The bent portion 23 extends by bending from the edge in the length direction of the first side plate 2 toward the first side plate 3. There is an engaging portion 202 on the bent portion 23. The engaging portion 202 is a plurality of bosses facing the inside of the inner box body 20. An insertion groove is formed between two adjacent bosses, and the bosses are arranged along the height direction of the inner box body 20. Similarly, the engaging portion 302 is a plurality of bosses facing the outside of the inner box body 20. An insertion groove is formed between two adjacent bosses, and the bosses are arranged along the height direction of the inner box body 20. The bosses of the engaging portion 302 are inserted into the insertion grooves of the engaging portion 202, and the bosses of the engaging portion 202 are inserted into the insertion grooves of the engaging portion 302, thereby realizing the engaging and fixing of the first side plates 2 and 3. When folding, the first side plate 3 can be folded downward first, and the first side plate 3 is located between the two edge guards 13. As Figure 11 、 Figure 13 and Figure 20 shown, the first side plate 2 is then folded downward. After folding, one of the first side plates 2 is located above the other first side plate 2. The first side plate 3 is folded first, and then the first side plate 2 is folded. The engaging portion 202 will not interfere with the engaging portion 303. The length of the second side plate 902 is greater than the length of the first side plate 3, and the second side plate 902 shields the engaging and docking area between the first side plate 3 and the first side plate 2. It can be understood that one second side plate 902 can shield the engaging and docking area between the first side plate 3 and the first side plate 2, or both second side plates 902 can shield the engaging and docking area between the first side plate 3 and the first side plate 2. It should be understood that the connection method between the first side plates 2 and 3 is not limited to the above-mentioned engaging method, as long as they can be connected end to end to enclose the internal space.

[0082] As Figure 7 、 Figure 8 and Figure 20As shown, at least one first connecting member 5 is embedded at the bottom of the first side plate 2 and the bottom of the first side plate 3. At least one second connecting member 6 is embedded on two pairs of opposite sides of the first base 1. A plurality of first connecting members 5 are respectively hinged to a plurality of second connecting members 6. It can be understood that the first connecting member 5 is integrally formed with the first side plates 2 and 3, being an independent integral part. Or the second connecting member 6 and the first base 1 are also integrally formed, being an independent integral part.

[0083] As Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, the first base 1 has a bottom plate 11 and two pairs of opposite side guards extending upward from two pairs of opposite edges of the bottom plate 11, namely side guard 12 and side guard 13. The second connecting member 6 is embedded in the side guard 12. The number of second connecting members 6 in one side guard 12 can be one or multiple. The second connecting member 6 is embedded in the side guard 13. The number of second connecting members 6 in one side guard 13 can be one or multiple. Among them, when the first side plate 2 is upright relative to the first base 1, a section extending downward from the top edge of the first side guard 12 overlaps with a section extending upward from the bottom edge of the corresponding first side plate 2. When the first side plate 3 is upright relative to the first base 1, a section extending downward from the top edge of the side guard 13 overlaps with a section extending upward from the bottom edge of the corresponding first side plate 3, thereby ensuring the sealing between the first side plate and the first base 1, reducing the energy loss in the inner box body 20, and ensuring the overall heat insulation effect of the inner box body 20. In this embodiment, when the first side plate 2 and the first side plate 3 are upright, it can be understood as the state of the first side plate 2 and the first side plate 3 under the normal use state of the inner box 100.

[0084] To make the heat preservation effect of the inner box 100 better, the inner box body 20 and the first lid 4 are generally made of EPS or EPP foaming materials. And this kind of material has good toughness and poor rigidity. The first connecting member 5 and the second connecting member 6 are thicker than ordinary engineering plastic parts to ensure the realization of their strength and functions, as Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, now the first connecting member 5 is embedded in the first side plate 2 and the first side plate 3, and the second connecting member 6 is embedded in the first base 1. By the first side plate covering a part of the first connecting member 5 and the first base 1 covering a part of the second connecting member 6, the first connecting member 5 is firmly connected to the first side plate, and the second connecting member 6 is firmly connected to the first base 1, realizing the foldability of the inner box body 20.

[0085] As Figure 7 , Figure 8As shown, the first side plate 2 is a long first side plate with a longer length, and the first side plate 3 is a short first side plate with a shorter length. The folding structure of the first side plate 2 and the edge guard 12 is similar to the folding structure of the first side plate 3 and the edge guard 13. Now, taking the folding structure of the first side plate 2 and the edge guard 12 as an example, a specific description is given. The first side plate 2 includes: a first side plate body 21 and an extension part 22 extending downward from the lower edge of the first side plate body 21, and the first connecting member 5 is at least partially embedded in the extension part 22. When each first side plate 2 is upright relative to the first base 1, the edge guard 12 overlaps with the extension part 22 of the corresponding first side plate 2, that is, the extension part 22 is located on the inner side surface of the edge guard 12 and is in contact with the inner side surface of the edge guard 12.

[0086] Further, as Figure 11 and Figure 18 shown, the extension part 22 has a groove with an opening 30 facing outward and downward, and the edge guard 12 is operably embedded in the groove 221. When the first side plate 2 is upright, the top of the edge guard 12 abuts against the downward side of the groove 221, and the inner side surface of the edge guard 12 is in contact with the side wall of the groove 221 facing it.

[0087] Further, as Figure 9 、 Figure 10 shown, each second connecting member 6 has a second inlay part 61 at least partially embedded in the corresponding edge guard 12 and a hinge part 62 connected to the second inlay part 61, and the hinge part 62 is arranged on the side of the corresponding edge guard 12 facing the inside of the inner box body 20. There are multiple extension parts 22, and at least two adjacent extension parts 32 are spaced apart to form a spacing area 220. The first connecting member 5 has a first inlay part 51 at least partially embedded in the extension part 33 and a hinge shaft 52 connected to the first inlay part 51, and the hinge shaft 52 is arranged in the spacing area 220. Among them, the hinge shaft 52 is rotatably and slidably connected to the hinge part 62.

[0088] Further, as Figure 11 、 Figure 12 、 Figure 13 、 Figure 15 shown, a longitudinal groove 621 with an open top is formed on the hinge part 62, and the hinge shaft 52 is at least partially received in the longitudinal groove 621. When the first side plate 2 is folded into the inner box body 20, the hinge shaft rotates in the longitudinal groove 621 and can slide along the longitudinal groove 621, so as to change the height of the first side plate 2 after folding.

[0089] Further, as Figure 16 、 Figure 17 shown, the first inlay part 51 is detachably connected to the hinge shaft 52. When the hinge shaft 52 is damaged, the hinge shaft 52 can be directly replaced, saving costs.

[0090] In addition, as Figure 12, Figure 16 , Figure 17 As shown in Figure 16 and Figure 17 , at least part of the first inlay portion 51 is located within the spacer 220. An installation position 533 is provided on the part of the first inlay portion 51 located within the spacer 220, and the hinge shaft 52 is arranged on the installation position 533.

[0091] Optionally, as Figure 12 , Figure 16 shown, the installation position 533 is a protrusion extending along the height direction of the first side plate. The hinge shaft 52 has a shaft body 521 and an installation sleeve 522 connected to the shaft body 521, and the installation sleeve 522 is slidably sleeved on the protrusion, making the installation and replacement of the hinge shaft 52 more convenient. It can be understood that the installation position 533 can also be a notch, and a boss can be provided on the hinge shaft 52 to be snapped into the notch.

[0092] Furthermore, as Figure 12 , Figure 17 shown, at least part of the first inlay portion 51 abuts against the side of the extension portion 22 that constitutes the spacer 220 facing the spacer 220. A fixing recess 530 is provided on the side of the part of the first inlay portion 51 abutting against the extension portion 22 facing the spacer 220. The top of the hinge portion 62 has a hook body 622 that snaps into the fixing recess 530. After the first side plate 2 is erected, the first side plate 2 and the first side plate 3 are engaged, the hook body 622 snaps into the fixing recess 530, and the edge guard 12 abuts against the downward side of the groove 221.

[0093] Optionally, the second inlay portion 61 and the hinge portion 62 connected to the second inlay portion 61 are integrally formed and can be a plastic or metal part. The first inlay portion 51 and the hinge shaft 52 connected to the first inlay portion 51 can also be integrally formed and can be a plastic or metal part.

[0094] Furthermore, the inner box body 20 is generally made of EPS or EPP foaming material. To ensure the heat preservation effect, the inner box body 20 is maintained at a certain thickness. To not change the volume size inside the inner box body 20 and yet ensure a certain thickness of the inner box body 20, the second connector 6 is embedded in the first base 1. And this material has good toughness and poor rigidity. To ensure the connection strength and stability between the second connector 6 and the first base 1. As Figure 9 , Figure 10 , Figure 12 shown, each second inlay portion 61 has a second hollow portion 610, and the edge guard 12 is partially filled in the second hollow portion 610, thereby reducing the material and weight of the second inlay portion 61 while making the connection between the second inlay portion 61 and the edge guard 12 closer. In addition, the first inlay portion 51 occupies less area of the edge guard 12, leaving more material for the edge guard 12, making the inner box body 20 have a better heat preservation effect.

[0095] Furthermore, asFigure 9 , Figure 10 , Figure 12 As shown in Figure 12 , the second embedding part 61 is provided with a second limiting member 612 for inserting the edge guard 12. The second limiting member 612 has second branch portions 613 extending in different directions, so that the connection strength between the second connecting member 6 and the first base 1 is higher.

[0096] In addition, as Figure 9 , Figure 10 , Figure 12 shown, on the region where the second embedding part 61 is embedded in the edge guard 13, there is also a second protruding part 611 extending outward from the second hollow part 610. The second protruding part 611 is embedded in the edge guard 13 filling the second hollow part 610. It can be understood that the second connecting member 6 embedded in the edge guard 12 can have the second protruding part 611 inserted into the edge guard 12.

[0097] Optionally, the second connecting member 6 and the first base 1 can be injection molded, and the second embedding parts 61 of the second connecting members 6 are embedded in the first base 1. Or, in other embodiments, the second connecting member 6 and the first base 1 are also an integral whole.

[0098] In addition, in order to ensure the connection strength and stability between the first connecting member 5 and the first base 1. As Figure 16 , Figure 17 shown, the first embedding part 51 has a first hollow part 510, and a part of the first side plate 2 is filled in the first hollow part 510. The extending part 22 of the first side plate 2 is partially filled in the first hollow part 510, and a part of the first side plate body 21 is also filled into the first hollow part 510. It can be understood that only the extending part 22 can be partially filled in the first hollow part 510. Thus, while reducing the material and weight of the first embedding part 51, the first embedding part 51 is more closely connected to the first side plate 2. In addition, the first embedding part 51 occupies less area of the first side plate 2, leaving more material for the first side plate 2, so that the inner box body 20 has a better heat preservation effect.

[0099] Furthermore, as Figure 13 , Figure 15As shown, the structure of the first side plate 3 is substantially the same as that of the first side plate 2. The first side plate 3 includes: a first side plate body 31 and an extension portion 32 extending downward from the lower edge of the first side plate body 31, and at least a part of the first connecting member 5 is embedded in the extension portion 32. The structure of the embedded first connecting member 5 is substantially the same as that of the first connecting member 5 embedded in the first side plate 2. In the structure of the first connecting member 5 embedded in the first side plate 3, the first inlay portion 51 further has a first protrusion 511 extending outward toward the first hollow portion 510, and the first protrusion 511 is embedded in the first side plate 2 filling the first hollow portion 510, so that the connection strength between the first connecting member 5 and the first side plates 2 and 3 is higher. It can be understood that the first connecting member 5 embedded in the first side plate 2 may also have the first protrusion 511 inserted into the first side plate 2. The technical detail structures of the first connecting member 5 embedded in the first side plate 2 and the first connecting member 5 embedded in the first side plate 3 can be applied to each other, and are not limited to being in one first side plate.

[0100] In addition, the first inlay portion 51 is provided with a first limiting member for inserting the edge guard. The first limiting member is a protrusion, and the protrusion has a first branch portion extending in different directions. Further, the connection strength between the first connecting member 5 and the first base 1 is higher.

[0101] Optionally, the first connecting member 5 and the first side plates 2 and 3 can be injection molded, and the first inlay portion 51 of each first connecting member 5 is embedded in the first connecting member 5 and the first side plates 2 and 3. Or, in other embodiments, the first connecting member 5 and the first side plates 2 and 3 are also an integral whole.

[0102] In addition, in some embodiments, such as Figure 16 and Figure 17 shown, the first connecting member 5 and the first side plate 2 are detachably connected. When the first connecting member 5 needs to be replaced, the first connecting member 5 can be peeled off from the corresponding first side plate. The first connecting member 5 is arranged on the side of the first side plate facing the inner box body 20. For the convenience of installing the first connecting member 5, the side of the first side plate facing the inner box body 20 matches the outer shape of the first connecting member 5, and the side of the first side plate facing the inner box body 20 has a boss that snaps into the first connecting member 5. The first side plate 3 and the first connecting member 5 can also be detachably connected, and the connection between the first side plate 3 and the first connecting member 5 and the cooperation between the first side plate 2 and the first connecting member 5 are the same, which will not be elaborated here.

[0103] As Figure 7 、 Figure 9 、 Figure 13As shown, the first side plate 2 is a long first side plate, the first side plate 3 is a short first side plate, the height of the edge guard 12 is higher than that of the edge guard 13, the length of the edge guard 12 is greater than that of the edge guard 13, the structures of the edge guard 12 and the edge guard 13 are substantially the same, the structures of the second connectors 6 embedded in the edge guard 12 and the edge guard 13 are substantially the same, and the structures of the first connectors 5 embedded in the first side plate 2 and the first side plate 3 are substantially the same. According to the length of the first side plate, the lengths of the first connector 5 and the second connector 6 will change accordingly. Correspondingly, the number of hinge shafts 52 of the first connector 5 on the first side plate 2 is greater than the number of hinge shafts 52 of the first connector 5 on the first side plate 3; the number of hinge portions 62 of the second connector 6 on the edge guard 12 is greater than the number of hinge portions 62 of the second connector 6 on the edge guard 13. Of course, the number of hinge shafts 52 of each first connector 5 and the number of hinge portions 62 of each second connector 6 can be changed according to the actual situation.

[0104] The structures of the first side plate 3, the edge guard 13, the first connector 5 embedded in the first side plate 3, and the second connector 6 embedded in the edge guard 13 are substantially the same as those of the first side plate 2, the edge guard 12, the first connector 5 embedded in the first side plate 2, and the second connector 6 embedded in the edge guard 12, and will not be described in detail here.

[0105] More notably, as Figure 8 , Figure 18 , Figure 19As shown in the figure, the inner box 100 further includes: a plurality of reset members 7, and the reset members 7 are connected to the first base 1 and at least one first side plate. The reset member 7 can be a spring or an elastic cord. Specifically, the first side plate 2 is provided with a first reset fixing member 71, the first base 1 is provided with a second reset fixing member 72, and both ends of the reset member 7 are respectively connected to the first reset fixing member 71 and the second reset fixing member 72. The first reset fixing member 71 can be stuck on the first connecting member 5 on the first side plate 2, and the second reset fixing member 72 is embedded in the edge guard 12. And a plurality of reset members 7 connecting the first side plate 2 and the first base 1 can be provided. One is provided at each of the two ends in the length direction of the first side plate 2. Thus, when the first side plate 2 is erected, with the pulling force of the reset member 7, it is convenient to erect the first side plate 2. The first reset fixing member 71 and the second reset fixing member 72 can have the same structure and both include: a fixing block 711 and a hook ring 712 provided on the fixing block. The fixing block of the first reset fixing member 71 is snapped into the first connecting member 5, and the fixing block of the second reset fixing member 72 is snapped into the second connecting member 6. Hooks are provided at both ends of the reset member 7, and the hooks can respectively hook the hook rings 712 of the first reset fixing member 71 and the second reset fixing member 72. In addition, the first side plate 3 and the first base 1 are also connected by the reset member 7. The first reset fixing member 71 can be arranged in the first connecting member 5 on the first side plate 3, and the second reset fixing member 72 is arranged on the bottom plate 11. Thus, when the first side plate 3 is erected, with the pulling force of the reset member 7, it is convenient to erect the first side plate 3. The number of the reset members 7 on the first side plate 3 can be one or more. It can be understood that the first reset fixing member 71 can be connected to the first side plate and the first connecting member 5. The second reset fixing member 72 can be connected to the bottom plate 11, the edge guard or the second connecting member 6.

[0106] According to actual requirements, there can be a reset member 7 on only one first side plate, or there can be reset members 7 on multiple first side plates.

[0107] Furthermore, as Figure 7 , Figure 11 , Figure 13 , Figure 20As shown, the first side plate 2 has a pair of bent portions 23. The bent portions 23 extend by bending from the edges in the length direction of the first side plate 2 towards the direction of the first side plate 3. There are engaging portions 202 on the bent portions 23. The engaging portions 202 are multiple bosses facing the inner box body 2020. An insertion groove is formed between two adjacent bosses, and the bosses are arranged along the height direction of the inner box body 20. Similarly, the engaging portion 302 is multiple bosses facing the outside of the inner box body 20. An insertion groove is formed between two adjacent bosses, and the bosses are arranged along the height direction of the inner box body 20. The bosses of the engaging portion 302 are inserted into the insertion grooves of the engaging portion 202, and the bosses of the engaging portion 202 are inserted into the insertion grooves of the engaging portion 302, thereby realizing the engaging and fixing of the first side plates 2 and 3. When folding, the first side plate 3 can be folded down first, and the first side plate 3 is located between the two edge guards 13. Then the first side plate 2 is folded down. After folding, one of the first side plates 2 is located above the other first side plate 2. The first side plate 3 is folded first, and then the first side plate 2 is folded, and the engaging portion 202 will not interfere with the engaging portion 303.

[0108] As Figure 2 and 20 shown, the first lid 4 has a first lid body 41 and a first cold storage member 42 provided on the first lid body 441. The first cold storage member 42 can be a cold storage plate filled with a cold storage agent inside. The first cold storage member 42 can also be provided on the side plate or the first base of the inner box 100.

[0109] In addition, as shown in Figure 14 and

[0110] shown, a handle 8 is also connected to one of the first side plates 3. The handle 8 is partially embedded in the first side plate 3. The handle 8 has an extended hook body 80 extending and embedded in the first side plate where the handle 8 is located, so that the handle 8 is more tightly fixed to the first side plate 3. The handle 8 can be provided in the other first side plate 3 or the first side plate 2. It can be provided on one first side plate or multiple first side plates.

[0111] In some embodiments, the first side plate 2 may not have the first connecting member 5, and the first base 1 may correspondingly not have the second connecting member. The first side plate 2 is directly hinged to the first base 1.

[0112] It can be understood that the inner box can also be of other structures. Another embodiment of the inner box in the present invention will be described below with reference to the accompanying drawings.

[0113] As Figure 21 , Figure 22 , Figure 26 and Figure 27As shown in the figure, the inner box 9100 includes an inner box body 920 having a first opening 930, a first lid 94 covering the first opening 930, and a first cold storage member 942 disposed within the inner box 100. The inner box body 920 has a first base 1 and two pairs of opposite first side plates 92 and 93 that are foldable with respect to the first base 91. Both the first side plate 92 and the first side plate 93 are hinged to the first base 91 through hinge members, and the hinge members operably cover the gap between the corresponding first side plate and the first base 91. As Figure 25 shown, the first side plate 92 is hinged to the first base 91 through a hinge member 95, and the first side plate 93 is hinged to the first base 91 through a hinge member 95. At each of the longitudinal ends of the first side plate 92 and the first side plate 93, there are engaging portions 9202 and 9302. When each first side plate is erected with respect to the first base 91, the hinge member 95 is straightened to cover the docking area between the first side plate 92 and the first base 91, the hinge member 96 is straightened to cover the docking area between the first side plate 93 and the first base 91, and the first side plates 92 and 93 are connected to each other by engaging with each other through the engaging portions 9202 and 9302, thereby jointly forming the internal volume of the inner box 100 with the first base 91, and the first lid 94 can cover the first opening 930 of the inner box 100. When each of the first side plates 92, 93 and the first lid 94 is folded with respect to the first base 91, the hinge members 95 and 96 are bent, reducing the volume of the inner box body 920, making it convenient for storage and transportation. It should be understood that the connection manner between the first side plates 92 and 93 is not limited to the above-mentioned engaging manner, as long as they can be joined end to end to enclose an internal space.

[0114] From the above, it can be seen that due to the provision of hinge members, the first side plates 92 and 93 are hinged to the first base 91 through the hinge members 95 and 96, so that the first side plates 92, the first side plates 93 and the first base 91 can be folded, which is convenient for storage and transportation, reduces the occupied space when transporting and storing the insulation box, and reduces the transportation and storage costs. Moreover, the hinge members cover the gap between the corresponding first side plate and the first base 91, reducing the energy loss at the hinged part of the inner box body 920 and enhancing the overall heat insulation effect of the inner box body 20.

[0115] The structures of the two first side plates 92 hinged to the first base 91 through the hinge member 95 are the same. Now, take the structure of one first side plate 92 connected to one hinge member 95 as an example. The hinge member 95 includes: a first mounting portion 951, a second mounting portion 952, and a connecting plate 953. The first mounting portion 951 is connected to the first side plate 92, the second mounting portion 952 is connected to the first base 91, the first mounting portion 951 and the second mounting portion 952 are disposed on the upper and lower sides of the connecting plate 953, and the connecting plate 953 covers the gap between the first side plate 92 and the first base 91.

[0116] Furthermore, as Figure 21 、 Figure 22, Figure 26 and Figure 27 As shown in Figure 26 and Figure 27 , the connecting plate 953 has a first mounting plate 9531 connected to the first mounting portion 951, a second mounting plate 532 connected to the second mounting portion 952, and a flexible plate 9533 connected to the first mounting plate 9531 and the second mounting plate 9532. The first mounting plate 9531 and the second mounting plate 9532 are disposed on the upper and lower sides of the flexible plate 9533. The first mounting plate 9531, the second mounting plate 9532, and the flexible plate 9533 all extend along the length direction of the first side plate 95. The thickness of the flexible plate 9533 is less than the thicknesses of the first mounting plate 9531 and the second mounting plate 9532, so that when the first side plate 92 is folded, the flexible plate 9533 can be bent, and the thicknesses of the second mounting plate 9532 and the first mounting plate 9531 can be maintained to enable the inner box body 920 to have good cold storage performance. It can be understood that the thicknesses of the flexible plate 9533, the second mounting plate 9532, and the first mounting plate 9531 can also be the same. The flexible plate 9533 can be a plastic part, a silicone part, or a steel plate. The flexible plate 9533, the second mounting plate 9532, and the first mounting plate 9531 can be an integral part of the same material, or the second mounting plate 532 and the first mounting plate 531 can be made of different materials from the flexible plate 9533, and the flexible plate 9533 is connected and spliced with the second mounting plate 9532 and the first mounting plate 9531.

[0117] Furthermore, as Figure 24 and Figure 26 and Figure 27 shown, the first mounting portion 951 has a plurality of first embedding bolts 9511 that are embedded in the corresponding first side plate 92. The first embedding bolts 9511 are arranged along the length direction of the first side plate 92.

[0118] Furthermore, as Figure 6 and Figure 7 shown, the second mounting portion 952 has a plurality of second embedding bolts 9521 that are embedded in the first base 91. The second embedding bolts 9521 are arranged along the length direction of the first side plate 92.

[0119] In addition, the first mounting portion 951, the second mounting portion 952, and the connecting plate 953 are integrally formed.

[0120] Furthermore, as Figure 21 and Figure 22 and Figure 26 and Figure 27As shown, the first side plate 92 has a first side plate body 921 and a first extension plate 922 extending downward from the bottom side of the first side plate body 921. The first base 91 has a first bottom plate 911 and a pair of opposite first edge guards 912 extending upward from a pair of opposite edges of the first bottom plate 911, and one first edge guard 912 corresponds to one first extension plate 922, and each first extension plate 922 is operably engaged with the corresponding first edge guard 912. Among them, each first extension plate 922 is connected to the first mounting portion 951, and each first edge guard 912 is connected to the second mounting portion 952. And the flexible plate 953 covers at least part of the first extension plate 922 and extends from the lower edge of the first extension plate 922 to the first edge guard 912 corresponding to the first extension plate 922.

[0121] Further, the inner box body 920 is generally made of EPS or EPP foaming material. To ensure the heat preservation effect, the inner box body 920 is maintained at a certain thickness. In order not to change the volume size inside the inner box body 920 and to ensure the thickness of the inner box body 920, the hinge is embedded on the inner box body 920. That is, at least part of the first mounting plate 9531 and the top of the flexible plate 9533 are embedded on the side of the first extension portion facing the inside of the inner box body 920, and at least part of the second mounting plate 9532 and the bottom of the flexible member are embedded on the side of the first edge guard 912 facing the inside of the inner box body 20. And the hinge 95 is on the inner side of the inner box body 920, keeping the structural integrity of the outer surface of the inner box body 920. It can be understood that the hinge 95 can be provided on the outer surface of the inner box body 920.

[0122] As Figure 21 、 Figure 22 、 Figure 23 、 Figure 26 and Figure 27 As shown, a first groove 9221 with a first opening 930 facing outward and downward is provided on the outer side of each first extension plate 922. The first edge guard 912 has a first protrusion 9121, and the first protrusion 9121 is embedded in the first groove 9221 of the corresponding first extension plate 922 and abuts against the wall surface of the first groove 9221. The flexible plate 533 covers the lower edge 9220 of the side of the first extension plate 922 facing the inside of the inner box body 20, and the flexible plate 9533 also covers the upper edge 9120 of the side of the first edge guard 912 facing the inside of the inner box body 920. Thus, the gap between the lower edge 9220 and the upper edge 9120 is covered by the flexible plate 9533, and the cold air inside the inner box body 920 will not flow out between the lower edge 220 and the upper edge 120. Even though the first side plate 2 and the first base 1 are not integral parts, the cold air inside the inner box body 20 is not likely to leak.

[0123] Further, as Figure 21 、 Figure 22 、 Figure 24 、Figure 26 and Figure 27 As shown, the provision of the first extension plate 22 facilitates the formation of a through hole 222 in the first extension plate 22. The first insertion bolt 511 is inserted into the through hole 222 and penetrates through the first extension plate 22. The hook body at the end of the first insertion bolt 511 hooks onto the first extension plate 22, thereby enabling the first insertion bolt 511 and the first side plate 2 to have a large positioning and fixing area. Even though the first side plate 2 has good toughness and poor rigidity, the first insertion bolt 511 is still stably connected to the first side plate 2. The first protrusion 121 abuts against the wall surface of the first groove 221, that is, the first protrusion 121 abuts against the side surface of the first extension plate 22 facing the outside of the inner box body 20. The first protrusion 121 blocks the through hole 222, preventing the leakage of cold air from the through hole 222 and also protecting the first insertion bolt 511. When the first side plate 2 is vertical, due to the structure where the first protrusion 121 abuts against the wall surface of the first groove 221, the combined thickness of the first protrusion 121 and the first extension plate 22 is basically the same as the thickness of the first side plate body 21, ensuring the thickness of the side wall of the inner box body 20 and providing good heat preservation performance.

[0124] Furthermore, as Figure 22 、 Figure 23 、 Figure 24 and Figure 27 shown, the first edge guard 12 has a first docking portion 123 that extends upward. The upper edge 9120 is on the first docking portion 9123. The first docking portion 9123 abuts against the lower bottom surface of the first extension plate 922, and the first docking portion 9123 is spaced apart from the first protrusion 9121, thereby facilitating the formation of a through hole 9122 in the first docking portion 9123. The second insertion bolt 9521 is inserted into the through hole 9122 and penetrates through the first docking portion 123. The hook body at the end of the second insertion bolt 521 hooks onto the side of the first docking portion 9123 facing the first protrusion 9121, thereby enabling the second insertion bolt 9521 and the first edge guard 912 to have a large positioning and fixing area. Even though the first base 1 has good toughness and poor rigidity, the second insertion bolt 9521 is still stably connected to the first edge guard 912. The first protrusion 9121 completely blocks the area between the first docking portion 9123 and the first extension plate 922 and also blocks the through hole 9122, preventing the leakage of cold air from the through hole 9222 and between the first docking portion 9123 and the first extension plate 922, and also protecting the second insertion bolt 9521.

[0125] In addition, as Figure 21 、 Figure 22 、 Figure 26 and Figure 27As shown, the first side plate 93 and the first base 91 are connected by a hinge member 96. The structure of the hinge member 96 can be the same as or different from that of the hinge 95. Now, taking the hinge member 96 as another structure, the connection between the first base 91 and the first side plate 93 will be described. Among them, the structures of the two first side plates 93 hinged to the first base 91 through the hinge member 96 are the same. Now, taking the structure of one first side plate 93 connected by one hinge member 96 as an example. The hinge member 96 includes: a first mounting portion 961, a second mounting portion 962, and a connecting plate 963. The first mounting portion 961 is connected to the first side plate 92, the second mounting portion 962 is connected to the first base 91, the first mounting portion 961 and the second mounting portion 962 are arranged on the upper and lower sides of the connecting plate 963, and the connecting plate 963 covers the gap between the first side plate 92 and the first base 91.

[0126] Further, as Figure 21 , Figure 22 , Figure 24 , Figure 26 and Figure 27 shown, the connecting plate 963 has a first mounting plate 9631 connected to the first mounting portion 961, a second mounting plate 9632 connected to the second mounting portion 962, and a flexible plate 9633 connected to the first mounting plate 9631 and the second mounting plate 9632, and the first mounting plate 631 and the second mounting plate 632 are arranged on the upper and lower sides of the flexible plate 9633. Among them, the first mounting plate 9631, the second mounting plate 9632, and the flexible plate 9633 all extend along the length direction of the first side plate 96. The thickness of the flexible plate 9633 is less than the thicknesses of the first mounting plate 9631 and the second mounting plate 9632, so that when the first side plate 93 is folded, the flexible plate 9633 is deformed under tension, and the thicknesses of the second mounting plate 9632 and the first mounting plate 9631 can be maintained to enable the inner box body 920 to have good cold storage performance. It can be understood that the thicknesses of the flexible plate 9633, the second mounting plate 9632, and the first mounting plate 9631 can also be the same. The flexible plate 9633 can be a plastic part, a silicone part, or a steel plate. The flexible plate 9633, the second mounting plate 9632, and the first mounting plate 9631 can be an integral part of the same material, or the second mounting plate 9632 and the first mounting plate 9631 can be made of different materials from the flexible plate 9633, and the flexible plate 9633 is connected and spliced with the second mounting plate 9632 and the first mounting plate 9631.

[0127] Further, the first mounting portion 961 has a number of first embedding bolts 9611 that are embedded in the corresponding first side plate 93. The first embedding bolts 9611 are arranged along the length direction of the first side plate 93. It can be understood that the first mounting portion can be an adhesive layer.

[0128] Furthermore, the second mounting portion 962 has a plurality of second embedding bolts 9621 that are embedded in the first base 91. The second embedding bolts 9621 are arranged along the length direction of the first side plate 93. It can be understood that the second mounting portion can be an adhesive layer.

[0129] In addition, the first mounting portion 961, the second mounting portion 962, and the connecting plate 963 are integrally formed.

[0130] Furthermore, as Figure 21 , Figure 22 , Figure 26 and Figure 27 shown, the first side plate 93 has a second first side plate body 931 and a second extension plate 932 that extends downward from the bottom side of the second first side plate body 931. The first base 91 also has a pair of opposite second edge guards 913 that extend upward from the other pair of opposite edges of the first bottom plate 911, and one second edge guard 913 corresponds to one second extension plate 932, and each second extension plate 932 is operably latched with the corresponding second edge guard 913. Among them, each second extension plate 932 is connected to a first mounting portion 961; the flexible plate 963 is operably wrapped around the lower corner end 320 of the second extension plate 932 facing the inside of the inner box body 20, the first mounting plate 9631 wraps the side of the second extension plate 932 facing the inside of the inner box body 920, and the second mounting plate 632 wraps the side of the second extension plate 32 facing the first bottom plate 911; the second mounting portion 962 extends downward and is connected to the first bottom plate 911, and the first mounting portion 961 is connected to the second extension plate 932.

[0131] Furthermore, as Figure 21 , Figure 22 , Figure 26 and Figure 27 shown, the first mounting plate 9631 is embedded in the side of the second extension plate 932 facing the inside of the inner box body 920, and the second mounting plate 9632 is embedded in the side of the second extension plate 932 facing the first bottom plate 911.

[0132] In addition, as Figure 21 , Figure 22 , Figure 24 , Figure 26 and Figure 27As shown, the first bottom plate 11 has a receiving portion 9110 disposed opposite to the second extension plate 32, and the second mounting portion is inserted into the receiving portion 9110. A through hole 9111 is formed in the receiving portion 9110. For the convenience of processing, the through hole 9111 penetrates the receiving portion 9110, and the second extension plate 932 blocks the through hole 9111, preventing the leakage of cold from the through hole 9111. Moreover, the position of the through hole 9111 also avoids the area on the first bottom plate 911 for placing items, allowing the items to be placed in the seamless area of the first bottom plate 911, ensuring the safety of the items. The area between the lower bottom surface of the second extension plate 932 and the receiving portion 9110 is blocked by the second mounting plate 9632 and the flexible plate 9633, preventing the leakage of cold from between the lower bottom surface of the second extension plate 932 and the receiving portion 9110. And the second mounting portion 962 extends downward to block part of the gap, further making the heat preservation effect of the inner box 100 better.

[0133] Further, as Figure 21 、 Figure 22 、 Figure 26 and Figure 27 shown, a second groove 9321 with a first opening 930 facing outward and downward is provided on the outside of each second extension plate 932. The second edge guard 913 is embedded in the corresponding second groove 9321 and abuts against the wall surface of the second groove 9321. The second edge guard 913 extends upward to block the area between the lower bottom surface of the second extension plate 32 and the receiving portion 9110. The setting of the second extension plate 932 facilitates the formation of a second through hole on the second extension plate 9932. The first embedding bolt 9611 is inserted into the second through hole and penetrates the second extension plate 932. The hook body at the end of the first embedding bolt 9611 hooks the second extension plate 932, thereby realizing a large positioning and fixing area between the first embedding bolt 9611 and the first side plate 93. Although the first side plate 93 has good toughness and poor rigidity, the first embedding bolt 611 is also stably connected to the first side plate 93. And the second edge guard 913 abuts against the wall surface of the second groove 9321, that is, the second edge guard 913 abuts against the side surface of the second extension plate 932 facing the outside of the inner box body 920. The second edge guard 913 blocks the second through hole, preventing the leakage of cold from the second through hole and protecting the first embedding bolt 9611. And when the first side plate 93 is vertical, through the structure of the second edge guard 913 abutting against the wall surface of the second groove 9321, the combined thickness of the second edge guard 913 and the second extension plate 932 is basically the same as the thickness of the second first side plate body 931, ensuring the thickness of the side wall of the inner box body 920 and having good heat preservation. And the first mounting plate 9631 extends upward beyond the height of the first embedding bolt 9611.

[0134] Furthermore, as Figure 21 、 Figure 22 、 Figure 26 and Figure 27As shown, the height of the first edge guard 912 is higher than that of the second edge guard 913.

[0135] As Figure 26 and Figure 27 shown, the first side plate 93 is operably folded into the inner box body 920 and abuts against the first bottom plate 911 after folding. The first side plate 92 is operably folded into the inner box body 920 and is located above the first side plate 93. That is, when folding, the first side plate 93 is first folded down, and then the first side plate 92 is folded down. Since the height of the first edge guard 912 is higher than that of the second edge guard 913, the first side plate 92 can be directly on the first side plate 93 after folding and will not be interfered by the first side plate 3 and unable to fold.

[0136] Furthermore, as Figure 21 、 Figure 25 、 Figure 26 and Figure 27 shown, the first side plate 2 has a pair of bending portions 923. The bending portions 923 extend by bending from the edges in the length direction of the first side plate 92 towards the direction of the first side plate 3. There are engaging portions 9202 on the bending portions 923. The engaging portions 9202 are multiple bosses facing the inside of the inner box body 920. An embedding groove is formed between two adjacent bosses, and the bosses are arranged along the height direction of the inner box body 920. Similarly, the engaging portions 9302 are multiple bosses facing the outside of the inner box body 920. An embedding groove is formed between two adjacent bosses, and the bosses are arranged along the height direction of the inner box body 920. The bosses of the engaging portions 9302 are inserted into the embedding grooves of the engaging portions 9202, and the bosses of the engaging portions 9202 are inserted into the embedding grooves of the engaging portions 9302, so as to realize the engaging fixation of the first side plates 2 and 3. When folding, the first side plate 93 can be first folded downwards, and the first side plate 93 falls down away from the receiving portion 9110 and is located between the two second edge guards 913. After the first side plate 92 is folded, the two bending portions 923 respectively abut against the tops of the two second edge guards 913. The first side plate 92 covers the first side plate 93. And the first lid 94 is operably covered above the first side plate 92, and a pair of opposite edges of the first lid 94 overlap on the top of the first edge guard 912.

[0137] In addition, as Figure 21 、 Figure 25 、 Figure 26 and Figure 27As shown in the figure, the first lid 94 has a first lid body 941 and a first cold storage member 942 provided on the first lid body 941. The first cold storage member 942 can be a cold storage plate filled with a cold storage agent inside. One side of the first lid 94 body facing the inner box 920 has a hook body 9420 for hooking the first cold storage member 942. After the first side plates 92 and 93 are folded, the hook body 9420 can be operatively lapped in the first groove 9221. This makes the volume of the folded thermal insulation box smaller. There are protrusions 9201 at the tops of both the first side plate 92 and the first side plate 93. There is a groove 9411 inside the first lid body 941. When the first side plate 92 and the first side plate 93 are upright, the first lid 94 is covered on the tops of the first side plate 92 and the first side plate 93, and the protrusions 9201 of the first side plate 92 and the first side plate 93 are inserted into the groove 9411 of the first lid body 941 to cover the inner box 920 with the first lid body 94. In order to make the first lid 94 cover more tightly, there is a hook body 9410 on the first lid body 941 for hooking the protrusion 9201 of the first side plate 93. When the first side plate 92 and the first side plate 93 are upright, it is the state when the thermal insulation box is actually in use.

[0138] Furthermore, as Figure 26 and Figure 27 shown, after the two first side plates 92 are folded, the two first side plates 92 do not overlap, that is, the total height of the two first side plates 2 is less than or equal to the length of one first side plate 93. After the two first side plates 93 are folded, the two first side plates 93 do not overlap, that is, the total height of the two first side plates 93 is less than or equal to the length of one first side plate 93.

[0139] In addition, as Figure 21 and Figure 26 shown, the first side plate 92 is a long first side plate with a longer length, and the first side plate 93 is a short first side plate with a shorter length. It can be understood that the first side plate 93 can be a long first side plate with a longer length, and the first side plate 92 is a short first side plate with a shorter length.

[0140] In addition, the materials of the hinge members 95 and 96 are different from those of the first side plates and the first base 91. The hinge members 95 and 96 can be made of materials such as plastic and silicone, and the first side plates and the first base 91 can be made of EPS and EPP foaming materials.

[0141] In an embodiment, the hinge member 5 can also be the structure of the hinge member 96 to hinge the first side plate 92 and the first base 91, that is, the structure of the hinge member 95 hinging the first side plate 92 and the first base 91 and the structure of the hinge member 96 hinging the first side plate 93 and the first base 91 can be mutually replaced or used in combination, not limited to the above examples.

[0142] The preferred embodiments of the present invention have been described in detail above. However, it should be understood that, if desired, aspects of the embodiments can be modified to incorporate aspects, features, and concepts of various patents, applications, and publications to provide additional embodiments.
