Description

Technical Field

[0001] This utility model relates to the field of folding furniture technology, and in particular to a folding cabinet. Background Technology

[0002] Wardrobes, shoe cabinets, and other storage cabinets are often bulky, making them inconvenient to move and store. To improve their portability and space adaptability, some storage cabinets have adopted a foldable design.

[0003] Existing folding cabinets generally adopt a folding method where the side panels are folded in the middle. This method results in a relatively large overall thickness after folding, and the structure is usually quite complex, lacking stability and durability, which affects the user experience. Utility Model Content

[0004] Therefore, it is necessary to provide a folding cabinet to address the above problems, thereby reducing the size of the folding cabinet in the folded state and improving its structural stability.

[0005] This utility model provides a folding cabinet, including at least two folding units arranged sequentially along a first preset direction; each folding unit includes two support structures and two side panels, the two support structures are stacked along the first preset direction, and the two side panels are arranged opposite to each other on both sides of the support structures along a second preset direction, forming a frame with the two support structures, the second preset direction being perpendicular to the first preset direction, and the two sides of the side panels are rotatably connected to the two support structures respectively, so as to switch between an unfolded state and a folded state. In the unfolded state, an accommodating space is formed within the frame; two folding units adjacent to each other along the first preset direction share one support structure, and the side panels of the two folding units sharing the same support structure can be rotated in opposite directions relative to the support structure to the folded state.

[0006] In the aforementioned folding cabinet, since adjacent folding units share a common support structure, and the two side panels sharing the same support structure fold in opposite directions, the thickness of the support structure and side panels in the folded state is minimized. This significantly reduces the overall thickness of the folding cabinet in the folded state, achieving more efficient space compression for easier transportation and storage. Furthermore, since the side panels themselves cannot be folded, the stability and reliability of the folding cabinet in the unfolded state are also improved. In addition, the simple structure simplifies the folding and unfolding operation steps, enhancing the user experience.

[0007] In one embodiment, the folding cabinet includes at least two groups of folding units arranged sequentially along a second preset direction, each group of folding units being formed by at least two folding units arranged sequentially along a first preset direction; two adjacent folding units along the second preset direction share a side panel.

[0008] In one embodiment, the support structure includes a shelf and a frame surrounding the shelf. The frame includes a support member and two connectors. The support member extends along the second preset direction. The two connectors are respectively disposed at both ends of the support member and form a U-shaped structure with the support member. The side plate is rotatably connected to the connectors. The support structures of two adjacent folding units along the second preset direction share one connector.

[0009] In one embodiment, the frame is detachably connected to the shelf; and / or, the connector is detachably connected to the support.

[0010] In one embodiment, the side of the side plate connected to the support structure is provided with an anti-rotation surface and a guide surface arranged sequentially along the second preset direction.

[0012] In one embodiment, the folding unit further includes a rear plate, which is disposed on one side of the frame along a third preset direction, the third preset direction being perpendicular to both the first preset direction and the second preset direction; in the unfolded state, the four sides of the rear plate are respectively connected to two of the supporting structures and two of the side plates.

[0013] In one embodiment, one side of the rear plate is rotatably connected to one of the supporting structures, and the other three sides of the rear plate are detachably connected to another supporting structure and / or two of the side plates, respectively; in the folded state, the rear plate can be rotated to be stacked with the supporting structures.

[0014] In one embodiment, the support structure rotatably connected to the rear plate is provided with a receiving groove, and in the folded state, the rear plate is received in the receiving groove; and / or, the side of the rear plate detachably connected to the support structure is provided with a third snap-fit ​​portion, and the support structure is provided with a fourth snap-fit ​​portion capable of snapping into the third snap-fit ​​portion; in the unfolded state, the third snap-fit ​​portion and the fourth snap-fit ​​portion snap into each other, and in the folded state, the third snap-fit ​​portion and the fourth snap-fit ​​portion separate; and / or, the side of the support structure opposite to the receiving space is provided with an anti-rotation portion, and in the unfolded state, the rear plate contacts the anti-rotation portion.

[0015] In one embodiment, the folding unit further includes a door that is closable on the side of the frame away from the rear panel. Attached Figure Description

[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application.

The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0043] Wardrobes, shoe cabinets, and other storage cabinets are bulky, making them inconvenient to move and store. To improve their portability and space adaptability, some storage cabinets adopt a foldable design. Existing folding cabinets generally use a folding method where the side panels fold in the middle. This method still results in a relatively large overall thickness after folding, and the structure is usually quite complex, lacking stability and durability, thus affecting the user experience.

[0044] To solve the above problems, such as Figures 1 to 20 As shown, this utility model provides a folding cabinet to reduce the size of the folding cabinet in the folded state and improve structural stability.

[0045] like Figures 1 to 3 As shown, the first preset direction is defined as the Z-axis, the second preset direction as the X-axis, and the third preset direction as the Y-axis. All three preset directions are perpendicular to each other. For ease of description, the following explanation uses +Z as the top, -Z as the bottom, Y as the left and right, +X as the front, and -X as the back. However, in actual use, users can adjust the placement of the folding cabinet according to their needs; no specific restrictions are imposed here.

[0046] like Figures 1 to 3As shown, specifically, the folding cabinet includes at least two folding units 100 arranged sequentially along a first preset direction; each folding unit 100 includes two support structures 10 and two side panels 20. The two support structures 10 are stacked along the first preset direction, and the two side panels 20 are arranged opposite to each other on both sides of the support structure 10 along a second preset direction, forming a frame with the two support structures 10. The upper and lower sides of the side panels 20 are rotatably connected to the two support structures 10 respectively, so as to switch between an unfolded state and a folded state. In the unfolded state, a storage space 30 for storing clothing, shoes and other items is formed inside the frame; two adjacent folding units 100 along the first preset direction share a support structure 10, and the side panels 20 of the two folding units 100 sharing a support structure 10 can be rotated in opposite directions relative to the support structure 10 to the folded state.

[0047] by Figures 4 to 5 For example, when there are two folding units 100, the two folding units 100 share a common support structure 10. In the unfolded state, the side plate 20 of the upper folding unit 100 can rotate relative to the support structure 10 in the +W direction to the folded state, and the side plate 20 of the lower folding unit 100 can rotate relative to the support structure 10 in the -W direction to the folded state. Conversely, in the folded state, the side plate 20 of the upper folding unit 100 can rotate relative to the support structure 10 in the -W direction to the unfolded state, and the side plate 20 of the lower folding unit 100 can rotate relative to the support structure 10 in the +W direction to the unfolded state. The two side plates 20 of the same folding unit 100 rotate in the same direction relative to the support structure 10.

[0048] In the folding cabinet provided by this utility model embodiment, since adjacent folding units 100 share a support structure 10, and the two side panels 20 sharing the support structure 10 are folded in opposite directions, the thickness of the support structure 10 and the side panels 20 in the folded state is minimized, thereby significantly reducing the overall thickness of the folding cabinet in the folded state and achieving more efficient space compression for easier transportation and storage. Furthermore, since the side panels 20 themselves cannot be folded, the stability and reliability of the folding cabinet in the unfolded state can also be improved. Moreover, the structure is simple, simplifying the folding and unfolding operation steps and enhancing the user experience.

[0049] Furthermore, when unfolded, the support structure 10 of the uppermost folding unit 100 is lifted, causing the entire folding cabinet to leave the ground. Under the action of gravity, the support structure 10 and the side panels 20 will separate from each other. Each side panel 20 rotates to a vertical position and is supported between the upper and lower support structures 10, thus stabilizing the folding cabinet in the unfolded state. The operation is simple and convenient.

[0050] like Figures 1 to 3As shown, the folding cabinet includes at least two sets of folding unit groups 1000 arranged sequentially along a second preset direction. Each folding unit group 1000 is formed by at least two folding units 100 arranged sequentially along a first preset direction. Two adjacent folding units 100 along the second preset direction share a side panel 20. In this way, users can choose the arrangement of the folding units 100 according to their actual needs and increase the overall storage capacity of the folding cabinet. Having two adjacent folding units 100 share a side panel 20 improves the integrity and consistency of the folding cabinet, ensuring that multiple folding unit groups 1000 can be unfolded or folded simultaneously, while also reducing the overall size of the folding cabinet in the folded state.

[0051] In the illustrated embodiment, the folding cabinet includes two sets of folding unit groups 1000, each set of folding unit groups 1000 including six folding units 100. Of course, in other embodiments, the number of folding unit groups 1000 can also be one, three, four or more, and each set of folding unit groups 1000 can include two, three, four, five, six or more folding units 100. The specific number can be adjusted according to actual storage needs, and this embodiment of the present invention does not impose specific limitations.

[0052] like Figure 1 and Figure 10 As shown, the support structure 10 includes a shelf 1 and a frame 2 surrounding the shelf 1. The frame 2 includes a support member 21 and two connectors 22. The support member 21 extends along a second preset direction, and the two connectors 22 are respectively disposed at both ends of the support member 21, forming a U-shaped structure with the support member 21. The side plate 20 is rotatably connected to the connectors 22. The frame 2 is used to connect each folding unit 100, ensuring the overall stability of the folding cabinet. The shelf 1 is used to carry items such as clothing and shoes, and can divide the folding cabinet into sections for user convenience. Specifically, the support structures 10 of two adjacent folding units 100 along the second preset direction share a connector 22 to improve the integrity and consistency of the folding cabinet and reduce the number of parts. Furthermore, the number of support members 21 can also be two, with the two support members 21 and the two connectors 22 forming a square structure.

[0053] like Figure 11As shown, in one embodiment, the shelf 1 and the frame 2 are detachably connected. This allows the user to choose whether or not to install the shelf 1 as needed. For example, when the volume of an item exceeds the capacity of the folding unit 100's storage space 30, the shelf 1 can be removed, allowing two or more folding units 100 to form a single integrated space, thereby expanding the applicability of the folding cabinet. Furthermore, the detachable connection between the shelf 1 and the frame 2 increases the modularity of the folding cabinet, facilitating cleaning, maintenance, or replacement of individual components, extending the overall lifespan of the cabinet. It also facilitates disassembly, packaging, and transportation of the shelf 1 and frame 2, reducing space requirements and lowering transportation costs. Of course, in other embodiments, the shelf 1 and frame 2 can also be a single unit, such as integrally molded, or fixedly connected by adhesives, fasteners, or other methods.

[0054] like Figures 10 to 12 As shown, in one embodiment, the connector 22 includes a first connecting portion 222 and a first supporting portion 223. The first connecting portion 222 extends along a third preset direction and includes a first side surface 2221 facing the support member 21. The first supporting portion 223 is disposed on the first side surface 2221 and is used to support the shelf 1 of the folding cabinet. The support member 21 includes a second connecting portion 213 and a second supporting portion 214 disposed on the side of the second connecting portion 213 facing the connector 22. The second connecting portion 213 is connected to the first connecting portion 222. The shelf 1 is supported on the first supporting portion 223 and the second supporting portion 214 and is detachably connected to the first supporting portion 223 and the second supporting portion 214. The first support part 223 and the second support part 214 support the shelf 1 from below, which can improve the stability and reliability of the shelf 1 and distribute the load of the shelf 1. The first connecting part 222 and the second connecting part 213 are connected to each other and located outside the first support part 223 and the second support part 214. While ensuring a reliable connection between the support member 21 and the connecting member 22, they can also prevent the shelf 1 from sliding relative to the frame 2, thereby avoiding the shelf 1 from tilting or falling.

[0055] Of course, in other embodiments, the shelf 1 may be mounted on the first support portion 223 and the second support portion 214 and detachably connected to the first connecting portion 222 and the second connecting portion 213; the frame 2 may only include the first support portion 223 and the second support portion 214 connected to each other, the shelf 1 may be mounted on the first support portion 223 and the second support portion 214 and detachably connected to the first support portion 223 and the second support portion 214; or, the frame 2 may only include the first connecting portion 222 and the second connecting portion 213 connected to each other, and the outer periphery of the shelf 1 may be detachably connected to the first connecting portion 222 and the second connecting portion 213.

[0056] like Figures 11 to 15As shown, in one embodiment, the shelf 1 and the frame 2 are detachably snapped together. This simplifies the connection between the shelf 1 and the frame 2, allowing for quick assembly and disassembly without the need for external tools, thus facilitating user operation and improving the usability and convenience of the folding cabinet.

[0057] like Figures 14 to 15 As shown, specifically, both the first support portion 223 and the second support portion 214 include a support surface 23 for mounting the shelf 1. The support surface 23 is provided with a fifth engaging portion 231, such as a first engaging groove 2311. The shelf 1 is provided with a first engaging block 11 that can engage with the first engaging groove 2311. From the end near the support surface 23 to the end away from the support surface 23, the cross-sectional size of the first engaging groove 2311 gradually decreases. In this way, the first engaging block 11 can automatically tighten the shelf 1, the support member 21, and the connecting member 22 during the process of engaging the first engaging groove 2311, effectively reducing or even eliminating the assembly gap between the shelf 1 and the frame 2, further improving the reliability of the connection between the shelf 1 and the frame 2, thereby improving the stability of the support structure 10 and preventing the support structure 10 from shaking or producing abnormal noise during use.

[0058] The number of first slots 2311 on the first support portion 223 can be one, two, three or more, and the multiple first slots 2311 are arranged at intervals along a third preset direction; similarly, the number of first slots 2311 on the second support portion 214 can be one, two, three or more, and the multiple first slots 2311 are arranged at intervals along a second preset direction. The first locking block 11 is arranged in a one-to-one correspondence with the first slots 2311 to ensure the stability and reliability of the connection between the shelf 1 and the frame 2.

[0059] like Figure 13 As shown, the outer surface of the first locking block 11 is further provided with a raised rib 12. The raised rib 12 increases the friction and interference between the first locking block 11 and the first locking groove 2311, making the two more firmly locked together and preventing the first locking block 11 from coming loose from the first locking groove 2311 when the shelf 1 is subjected to vibration or load, thus ensuring the long-term reliability of the connection. Of course, the friction between the first locking block 11 and the first locking groove 2311 can also be increased by making the outer surface of the first locking block 11 or the inner surface of the first locking groove 2311 a rough surface.

[0060] Of course, in other embodiments, the fifth snap-fit ​​part 231 can also be a snap-fit ​​structure such as an elastic buckle to snap-fit ​​with the frame 2; or, the shelf 1 and the frame 2 can also be detachably connected by plug-in, interference fit or detachable screws, bolts or other fasteners, as long as the stability and reliability of the two in the assembled state can be ensured. This utility model embodiment does not make specific limitations here.

[0061] like Figure 1and Figure 17 As shown, when the support structures 10 of two adjacent folding units 100 along the second preset direction share a single connector 22, the first connector 222 includes two opposing first side surfaces 2221, and the number of first support parts 223 is two, with the two first support parts 223 respectively disposed on the two first side surfaces 2221. The two first support parts 223 are respectively used to support the left and right side panels 1. In this way, the versatility and standardization of the connector 22 can be improved, the number of molds and production costs can be reduced, and the production and assembly process can be simplified.

[0062] like Figure 1 and Figure 16 As shown, when the connector 22 is located on the left and right sides of the folding cabinet, to avoid the first connecting part 222 protruding from the outer surface of the folding cabinet and affecting its aesthetics, the number of first support parts 223 is usually one, thus improving the overall aesthetics of the folding cabinet. Of course, users can also install connectors 22 with two first support parts 223 on the left and right sides of the folding cabinet according to actual needs, improving the compatibility of the connector 22.

[0063] like Figure 11 As shown, in one embodiment, the connector 22 and the support 21 are detachably connected. Specifically, the connector 22 and the support 21 are detachably connected via a second connecting portion 213 and a first connecting portion 222. In this way, each component can be replaced independently, further improving the modularity of the folding cabinet, reducing manufacturing and maintenance costs, and also facilitating the disassembly, packaging, and transportation of the connector 22 and support 21, reducing space occupation and transportation costs. Of course, in other embodiments, the connector 22 and the support 21 can also be a single unit, such as integrally molded, or fixedly connected by adhesives, fasteners, or other methods.

[0064] like Figures 16 to 17 As shown, in one embodiment, the two ends of the support member 21 are detachably snapped into two connectors 22. This simplifies the connection between the support member 21 and the connectors 22, allowing for quick assembly and disassembly without the need for external tools, thus facilitating user operation and improving the usability and convenience of the folding cabinet.

[0065] Specifically, the first side 2221 of the connector 22 is provided with a sixth engaging portion 224, such as a second slot 2241. Both ends of the support member 21 are provided with second locking blocks 212 that can engage with the second slot 2241. The second locking blocks 212 and the second slot 2241 have simple structures, which facilitates processing and assembly. Furthermore, when the first locking block 11 engages with the first slot 2311 to tighten the shelf 1 with the support member 21 and the connector 22, the second locking blocks 212 and the second slot 2241 can also be tightened, effectively reducing or even eliminating the assembly gap between the connector 22 and the support member 21, and further improving the stability of the frame 2.

[0066] Of course, in other embodiments, the sixth snap-fit ​​part 224 can also be an elastic snap-fit ​​or other snap-fit ​​structure that snaps into the support member 21; or, the connector 22 and the support member 21 can also be detachably connected by plugging, interference fit or by detachable screws, bolts or other fasteners, as long as the stability and reliability of the two in the assembled state can be ensured. This utility model embodiment does not make specific limitations here.

[0067] like Figure 8 , Figure 15 and Figure 16 As shown, in one embodiment, the first connecting portion 222 further includes a second side surface 2222 that is perpendicular to and adjacent to the first side surface 2221. The connector 22 further includes a first mounting portion 225 disposed on the second side surface 2222. The first mounting portion 225 is provided with one of a first rotating shaft 204 and a first shaft hole 2251 extending along a third preset direction. The side plate 20 is provided with the other of the first rotating shaft 204 and the first shaft hole 2251. The first mounting portion 225 and the side plate 20 are rotatably connected by the first rotating shaft 204 and the first shaft hole 2251. In the illustrated embodiment, the first mounting portion 225 is provided with the first shaft hole 2251, and the side plate 20 is provided with the first rotating shaft 204. Thus, the connection structure between the side plate 20 and the connector 22 is simple, facilitating processing and assembly. Furthermore, the first rotating shaft 204 and the first shaft hole 2251, through their cooperation, can limit the rotation axis of the side plate 20 relative to the connector 22, improving the stability of the side plate 20 during rotation.

[0068] Furthermore, the rotation function of rotating the side panel 20, the support function of supporting the shelf 1, and the installation function with other structures are integrated into a connector 22, which improves the integration, reduces the number of parts, simplifies the overall structure of the folding cabinet, and thus reduces processing and assembly costs. In addition, the connector 22 as a whole can also prevent loosening after long-term use, thereby improving the integrity, stability and reliability of the folding cabinet, extending its service life and enhancing the user experience.

[0069] like Figure 16As shown, specifically, the first mounting part 225 includes two mounting blocks 2252, which are respectively disposed at both ends of the second side surface 2222. A first rotating shaft 204 or a first shaft hole 2251 is provided on the opposite side of the two mounting blocks 2252. The mounting blocks 2252 at both ends provide two stable and reliable hinge points for the side panel 20, effectively preventing the side panel 20 from shaking or jamming during rotation, ensuring the stability of the folding cabinet during folding and unfolding, and also preventing the side panel 20 from sliding along a third preset direction, thus improving the overall strength and stability of the folding cabinet.

[0070] Of course, in other embodiments, the side plate 20 and the connector 22 can also be connected by other structures such as hinges or joints, as long as they can be rotated together. This embodiment of the present invention does not impose any specific limitations.

[0071] like Figure 1 and Figure 16 As shown, when two adjacent folding units 100 along a first preset direction share a support structure 10, the first connecting part 222 includes two opposing second side surfaces 2222, and the number of first mounting parts 225 is two, with the two first mounting parts 225 respectively disposed on the two second side surfaces 2222. The two first mounting parts 225 are respectively used to connect the upper and lower side plates 20. In this way, the versatility and standardization of the connecting parts 22 can be improved, the number of molds and production costs can be reduced, and the production and assembly process can be simplified.

[0072] like Figure 1 and Figure 16 As shown, when the connector 22 is located on the upper and lower sides of the folding cabinet, to avoid the first mounting part 225 protruding from the outer surface of the folding cabinet and affecting its aesthetics or stability when standing on the bottom, the number of first mounting parts 225 is usually one, thus improving the overall aesthetics and stability of the folding cabinet. Of course, users can also install connectors 22 with two first mounting parts 225 on the upper and lower sides of the folding cabinet according to actual needs, improving the compatibility of the connectors 22.

[0073] like Figure 1 and Figure 18As shown, further, when the support structure 10 is located on the upper and lower sides of the folding cabinet as a whole, the support structure 10 may also include an end plate 4. The end plate 4 can be set above or below the original frame 2 and shelf 1. Alternatively, the end plate 4 can replace the shelf 1. In this case, one of the second sides 2222 of the connector 22 is provided with a first mounting part 225, and the other second side 2222 is provided with a third locking block 227 that can be detachably engaged with the end plate 4. In this way, the overall aesthetics and stability of the folding cabinet can be further improved. The number of third locking blocks 227 on the connector 22 can be one, two, three, four or more, and the multiple third locking blocks 227 are arranged at intervals along a third preset direction to ensure the stability and reliability of the connection between the end plate 4 and the connector 22. In addition, the support member 21 may also be provided with a third locking block 227 that can be detachably engaged with the end plate 4, or the support member 21 may be omitted.

[0074] like Figures 6 to 8 As shown, the side plate 20 connected to the support structure 10 has an anti-rotation surface 201 and a guide surface 202 arranged sequentially along a second preset direction. In the unfolded state, the anti-rotation surface 201 contacts the support structure 10; the side plate 20 can rotate relative to the support structure 10 toward the guide surface 202 to a folded state. The contact between the anti-rotation surface 201 and the support structure 10 means that they may abut against each other, or there may be no interaction force between them. Specifically, as... Figure 8 As shown, the upper side panel 20 can only rotate in the +W direction to the folded state, while the lower side panel 20 can only rotate in the -W direction to the folded state. Thus, by cooperating with the support structure 10, the anti-rotation surface 201 restricts the rotation of the side panel 20 relative to the support structure 10 towards the anti-rotation surface 201, providing clear limits and guidance for the rotation of the side panel 20. The guide surface 202 also makes the rotation of the side panel 20 smoother, preventing jamming. Furthermore, when the anti-rotation surface 201 abuts against the support structure 10, it also improves the stability of the side panel 20 in the unfolded state, reducing the possibility of accidental folding. The guide surface 202 can be the curved surface shown in the figure, or it can be an inclined surface or other guiding structures.

[0075] like Figure 7 , Figure 8 and Figure 16As shown, in one embodiment, the side panel 20 connected to the support structure 10 is provided with a first latching portion 203, and the support structure 10 is provided with a second latching portion 221 that can latch and engage with the first latching portion 203. In the unfolded state, the first latching portion 203 and the second latching portion 221 are latched and engaged; in the folded state, the first latching portion 203 and the second latching portion 221 are separated. The latching and engaging of the first latching portion 203 and the second latching portion 221 can further improve the stability and reliability of the side panel 20 in the unfolded state, prevent the side panel 20 from being accidentally folded, and reduce the shaking of the folding cabinet during use. The separation of the first latching portion 203 and the second latching portion 221 will not affect the normal rotation of the side panel 20. Furthermore, the assembly and disassembly of the first latching portion 203 and the second latching portion 221 are simple and easy for users to operate.

[0076] Specifically, one of the first latching portion 203 and the second latching portion 221 is a latching groove, and the other is a latching block that can engage with the latching groove. The number of first latching portions 203 can be one, two, three, four, or more, and multiple first latching portions 203 are arranged at intervals along a third preset direction. The second latching portions 221 are arranged in a one-to-one correspondence with the first latching portions 203 to ensure the stability and reliability of the side panel 20 in the unfolded state. Of course, the first latching portions 203 and the second latching portions 221 can also be other latching structures such as elastic buckles; this embodiment of the present invention does not impose specific limitations.

[0077] like Figure 16 As shown, in one embodiment, the first connecting part 222, the first supporting part 223, and the first mounting part 225 are integrally formed. This ensures the structural strength and dimensional accuracy of the connector 22, avoids loosening or assembly errors caused by connecting multiple parts, and also reduces assembly steps, improves production efficiency, and lowers costs. Of course, in other embodiments, the various parts of the connector 22 can also be processed separately and fixed together by adhesives, fasteners, or other methods, as long as the reliability of the connector 22 can be guaranteed. This embodiment of the present invention does not impose specific limitations here.

[0078] like Figure 1 and Figure 6 As shown, the folding unit 100 also includes a back panel 40, which is disposed on one side of the frame along a third preset direction. In the unfolded state, the four sides of the back panel 40 are respectively connected to two support structures 10 and two side panels 20. The back panel 40 closes the rear of the accommodating space 30, preventing items inside the accommodating space 30 from falling from the rear. Furthermore, when the four sides of the back panel 40 are respectively connected to the two support structures 10 and the two side panels 20, the side panels 20 cannot rotate relative to the support structures 10, thereby enhancing the strength of the folding unit 100 and making the folding cabinet more stable and aesthetically pleasing.

[0079] like Figure 5 As shown, in one embodiment, one side of the rear plate 40 is rotatably connected to one of the support structures 10, and the other three sides of the rear plate 40 are detachably connected to another support structure 10 and two side plates 20, respectively. In the folded state, the rear plate 40 can rotate to be stacked with the support structure 10. When folding is required, the three sides of the rear plate 40 are first separated from the support structure 10 and the two side plates 20, and the rear plate 40 is controlled to rotate to the position where the support structure 10 is stacked, so that the rear plate 40 does not interfere with the rotation of the side plates 20. Then, the side plates 20 are controlled to rotate relative to the support structure 10 to the folded state. In this way, the stability and reliability of the rear plate 40 in the unfolded state can be guaranteed, and the rear plate 40 does not need to be disassembled when folding, thereby reducing the number of parts and facilitating transportation and storage. Of course, in other embodiments, the four sides of the rear plate 40 can also be detachably connected to two support structures 10 and two side plates 20, respectively. When folding is required, the rear plate 40 is first disassembled, and then the side plates 20 are controlled to rotate relative to the support structure 10 to the folded state.

[0080] like Figure 9 and Figure 12 As shown, the first side 2221 is provided with one of a second rotating shaft 402 and a second shaft hole 2223 extending along a second preset direction. The second rotating shaft 402 or the second shaft hole 2223 is disposed near the end of the first connecting part 222. The rear plate 40 is provided with the other of the second rotating shaft 402 and the second shaft hole 2223. The first connecting part 222 and the rear plate 40 are rotatably connected by the second rotating shaft 402 and the second shaft hole 2223.

[0081] In the illustrated embodiment, the first side 2221 is provided with a second shaft hole 2223, and the rear plate 40 is provided with a second rotating shaft 402. Thus, the connection structure between the rear plate 40 and the connecting member 22 is simple, facilitating processing and assembly. Furthermore, the cooperation of the second rotating shaft 402 and the second shaft hole 2223 limits the rotation axis of the rear plate 40 relative to the connecting member 22, improving the stability of the rear plate 40 during rotation. Simultaneously, the first connecting portions 222 at both ends provide two stable and reliable hinge points for the rear plate 40, effectively preventing wobbling or jamming during rotation, ensuring the stability of the folding cabinet during folding and unfolding, and also preventing the rear plate 40 from sliding along the second preset direction, thus improving the overall strength and stability of the folding cabinet.

[0082] Of course, in other embodiments, the support member 21 may have one of a second rotating shaft 402 and a second shaft hole 2223 extending in a second preset direction, and the rear plate 40 may have the other of a second rotating shaft 402 and a second shaft hole 2223. The support member 21 and the rear plate 40 may be rotatably connected through the second rotating shaft 402 and the second shaft hole 2223. Alternatively, the rear plate 40 and the connecting member 22 may be connected by other structures such as hinges or joints, as long as a rotatable connection between the two can be achieved. This embodiment of the present invention does not impose specific limitations here.

[0083] like Figure 3 and Figure 5 As shown, the support structure 10, which is rotatably connected to the rear panel 40, is provided with a receiving groove 3. In the folded state, the rear panel 40 is received in the receiving groove 3. The receiving groove 3 prevents the rear panel 40 from protruding excessively from the support structure 10 in the folded state, thereby avoiding interference of the rear panel 40 with the rotation of the side panel 20. It also further reduces the overall thickness of the folding cabinet in the folded state, making it easier to transport and store.

[0084] like Figure 9 , Figures 19 to 20 As shown, in one embodiment, the side of the rear panel 40 that is detachably connected to the support structure 10 is provided with a third latching part 401, and the support structure 10 is provided with a fourth latching part 211 that can latch and engage with the third latching part 401. In the unfolded state, the third latching part 401 and the fourth latching part 211 latch and engage; in the folded state, the third latching part 401 and the fourth latching part 211 separate. The latching engagement of the third latching part 401 and the fourth latching part 211 can further improve the stability and reliability of the rear panel 40 in the unfolded state, prevent the rear panel 40 from folding accidentally, and reduce the shaking of the folding cabinet during use. The separation of the third latching part 401 and the fourth latching part 211 will not affect the normal rotation of the rear panel 40. Furthermore, the assembly and disassembly of the third latching part 401 and the fourth latching part 211 are simple and easy for users to operate.

[0085] Specifically, one of the third latching portion 401 and the fourth latching portion 211 is a latching groove, and the other is a latching block that can engage with the latching groove. The number of third latching portions 401 can be one, two, three, four, or more, and multiple third latching portions 401 are arranged at intervals along a second preset direction. The fourth latching portions 211 are arranged in a one-to-one correspondence with the third latching portions 401 to ensure the stability and reliability of the rear plate 40 in the unfolded state. Of course, the third latching portions 401 and the fourth latching portions 211 can also be other latching structures such as elastic buckles; this embodiment of the present invention does not impose specific limitations.

[0086] like Figure 20As shown, the support structure 10 has an anti-rotation part 24 on the side opposite to the receiving space 30. In the unfolded state, the rear plate 40 contacts the anti-rotation part 24. Contact between the rear plate 40 and the anti-rotation part 24 means that they may abut each other, or there may be no interaction force. Specifically, the rear plate 40 can only rotate forward to the folded state. Thus, by cooperating with the anti-rotation part 24, the rear plate 40's rearward rotation relative to the support structure 10 is restricted, providing a clear limit and guide for the rotation of the rear plate 40. Furthermore, the contact between the rear plate 40 and the anti-rotation part 24 also improves the stability of the rear plate 40 in the unfolded state, reducing the possibility of accidental folding. The anti-rotation part 24 can be provided on the connector 22 or the support member 21.

[0087] like Figure 1 As shown, the folding unit 100 also includes a door 50, which is closable and located on the side of the frame away from the back panel 40. The door 50 can close the front of the storage space 30, improving the overall aesthetics of the folding cabinet and effectively preventing dust and moisture, protecting the items inside the storage space 30, and expanding the applicability of the folding cabinet. Each folding unit 100 can have one door 50, or two, three, or more folding units 100 can share one door 50. The specific configuration can be adjusted according to actual needs, and this embodiment of the invention does not impose specific limitations.

[0088] like Figure 4 and Figure 16 As shown, in one embodiment, the connector 22 further includes a second mounting portion 226 disposed at one end of the first connecting portion 222 along a third preset direction. The second mounting portion 226 is used for rotatable connection with the door 50 of the folding cabinet. The second mounting portion 226 serves as a hub connecting the frame and the door 50, concentrating the rotatable connections of all moving parts, such as the side panel 20, the rear panel 40, and the door 50, on the connector 22, thus improving the overall integrity and assembly convenience of the folding cabinet. Furthermore, the door 50 is detachably connected to the second mounting portion 226. When folding is required, the door 50 is first detached, and then the side panel 20 is controlled to rotate relative to the support structure 10 to the folded state. Additionally, the user can choose whether to install the door 50 according to actual needs.

[0089] like Figure 11 As shown, to avoid the second mounting part 226 protruding from the outer surface of the folding cabinet and affecting its aesthetics, the second mounting part 226 can be provided only on the connector 22 where the door 50 needs to be installed, thereby improving the overall aesthetics of the folding cabinet. Of course, users can also provide the second mounting part 226 on all connectors 22 according to actual needs, improving the compatibility of the connectors 22.

[0090] Of course, in other embodiments, the door 50 can also be rotatably connected to the front side of the side panel 20 or the shelf 1. When the door 50 is rotatably connected to the front side of the shelf 1, the door 50 can also be folded in the same way as the rear panel 40, so that the door 50 does not need to be disassembled, thereby reducing the number of parts and facilitating transportation and storage.

[0091] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
