[0043] <Example 1>

[0044] This embodiment proposes a folding storage device, such as Figures 1-4 As shown, the cabinet body is formed by a first component and a folding unit 100. The folding unit includes a second component, a front wall portion, a rear wall portion and two side wall portions located between the first component and the second component. In this embodiment, the first component, the second component, the front wall portion, the rear wall portion and the side wall portion are all plate-like structures, so the first component, the second component, the front wall portion, the rear wall portion and the side wall portion can also be referred to as the top plate 1, the bottom plate 2, the front plate 4, the rear plate 3 and the two side plates. Among them, the two side plates have the same structure and are symmetrically arranged, and are divided into a left side plate 5 and a right side plate 6. The top ends of the left side plate 5 and the right side plate 6 are slidably arranged on the left and right sides of the bottom surface of the top plate 1 through a sliding assembly, and the bottom ends are rotatably arranged on the bottom plate 3 through a side wall rotating assembly; the top ends of the rear plate 3 and the front plate 4 can be detachably arranged on the top plate 1, and the bottom ends are rotatably arranged on the bottom plate 2 through the rear wall rotating assembly and the front wall rotating assembly respectively.

[0045] This embodiment has a folding state and a use state. When in the storage state, a storage space is formed between the top plate 1, the bottom plate 2, the front plate 4, the back plate 3 and the two side plates; when folded, as shown in FIG. Figure 4 As shown, first rotate and fold the front panel 4 into the cabinet so that the front panel 4 is stacked on the bottom panel 2, and then rotate and fold the back panel 3 into the cabinet so that the back panel 3 is stacked on the front panel 4. Finally, press down the top panel 1, causing the upper ends of the left and right panels 5 and 6 to slide along the length direction of the top panel 1, and rotate the lower ends into the cabinet so that the left and right panels 5 and 6 are folded until they are stacked on the back panel 3. At the same time, the top panel 1 is covered on the folded side panels, back panel 3 and front panel 4, and finally a panel is formed as shown in FIG. Figure 3 On the contrary, when the cabinet needs to be assembled, first pull up the top plate 1, causing the upper ends of the left and right panels 5 and 6 to slide along the length direction of the top plate 1, and the lower ends to rotate and unfold outside the cabinet. After the left and right panels 5 and 6 are turned to the vertical state, the rear panel 3 and the front panel 4 are turned outward to the vertical state to complete the assembly, forming the following Figure 1Shown in assembled state of use.

[0046] like Figure 5 As shown, taking the left side panel 5 as an example, the sliding assembly has sliding parts 51 formed on both sides of the top of the side panel 5, and sliding grooves 11 opened on both sides of the inner side of the top panel 1. The sliding part 51 is a cylindrical shaft, and the sliding groove 11 is a strip groove opened along the length direction of the top panel 1. The sliding part 51 is inserted into the sliding groove 11 and can slide along the sliding groove 11. When in use, the side of the front panel 4 and the rear panel 3 facing the left side panel 5 and the right side panel 6 can be pressed against the inner side of the edge of the left side panel 5 and the right side panel 6 to prevent the left side panel 5 and the right side panel 6 from moving (moving and rotating) or collapsing when in use, which greatly improves the stability of the structure (such as Figure 8 As shown, the side edge of the rear panel 3 abuts against the rear edge of the inner side of the left side panel 5).

[0047] In order to further improve the stability in use, a first limiting portion is provided on the top plate 1 at a position corresponding to the side plate to limit the top end of the side plate to prevent the side plate from moving or collapsing. The first limiting portion is a first limiting rib 12 formed on the inner side of the top plate 1. A first hook 13 is formed on the first limiting rib 12. The outer side of the first hook 13 forms a first blocking surface 131, and the inner side forms a first inclined guide surface 132. Figure 5 As shown, when the left side panel 5 and the top panel 1 are in the unfolded state (perpendicular to each other), the first blocking surface 131 abuts against the top inner edge of the left side panel 5, thereby limiting and supporting the left side panel 5 and enhancing the stability of the structure. The first inclined guide surface 132 can guide the left side panel 5 into the position between the first hook 13 and the edge of the top panel 1 during assembly, so that the first blocking surface 131 abuts against the top inner edge of the left side panel 5, forming a perpendicular state between the left side panel 5 and the top panel 1.

[0048] like Figure 5-Figure 7 As shown, the top plate 1 has a plate body 14 and a frame 15. In this embodiment, the plate body 14 and the frame 15 are integrally formed. The frame 15 is formed by extending the edge of the plate body 14 toward the side where the bottom plate 2 is located. The inner side of the frame 15 is provided with a slide groove portion 11. The inner side of the frame 15 is located below the slide groove portion 11 and has a step surface 151 formed thereon, which abuts against the top edge of the bottom plate 2 in the folded state. Figure 7 As shown, when in the folded state, the left side panel 5, right side panel 6, rear panel 3, and front panel 4 are placed in the space enclosed between the top panel 1 and the bottom panel 2, so that the folded state can be stable and the internal panels cannot fall out. In actual situations, the panel body 14 and the frame 15 can also be provided separately. For example, the panel body 14 can be rotatably or detachably connected to the hollow portion in the middle of the frame 15. In this way, the top panel 1 can be opened from the top, making it convenient for users to place items from top to bottom.

[0049] like Figure 8 As shown, the top of the rear panel 3 abuts against the inner side of the frame 15 of the top panel 1. A first stopper is provided on the panel body 14 at a position corresponding to the top of the rear panel 3, preventing the top of the rear panel 3 from moving or collapsing. This first stopper is a first stopper rib 12 formed on the inner side of the panel body 14. This first stopper rib 12 is formed with a first hook 13. The outer side of this first hook 13 forms a first blocking surface 131, and the inner side forms a first inclined guide surface 132. When the rear panel 3 and the top panel 1 are in the deployed position (perpendicular to each other), the first blocking surface 131 abuts against the inner edge of the top of the rear panel 3, thereby limiting and supporting the rear panel 3 and enhancing the stability of the structure. During assembly, the first inclined guide surface 132 guides the top of the rear panel 3 between the first hook 13 and the frame 15, allowing the first stopper 131 to abut against the inner edge of the top of the rear panel 3, thereby achieving a perpendicular position between the rear panel 3 and the top panel 1.

[0050] At the same time, the top cover of the rear panel 3 is provided on the side where the opening of the chute portion 11 is located. The left side panel 5 is provided with a second limiting portion near the rear panel 3 for limiting the side of the rear panel 3 to prevent the rear panel 3 from moving or collapsing. The second limiting portion is a second limiting rib 52 formed on the inner side of the left side panel 5. A second hook 53 is formed on the second limiting rib 52. The outer side of the second hook 53 forms a second blocking surface 531, and the inner side forms a second inclined guide surface 532. Figure 8 As shown, when the rear panel 3 and the left side panel 5 are in the unfolded state (perpendicular to each other), the second blocking surface 531 abuts against the side edge of the rear panel 3, thereby limiting and supporting the rear panel 3 and enhancing the stability of the structure. The second inclined guide surface 532 can guide the rear panel 3 to the position between the second hook 53 and the edge of the left side panel 5 during assembly, so that the second blocking surface 531 abuts against the side edge of the rear panel 3, thereby forming a perpendicular state between the rear panel 3 and the left side panel 5.

[0051] like Figure 9 As shown, the front panel 4 comprises a frame 41 and a panel 42. The bottom end of the frame 41 is pivotally mounted on the bottom panel 2 via a front wall pivot assembly, and the top end is detachably mounted on the top panel 1. The bottom end of the panel 42 is pivotally mounted on the bottom of the frame 41 via a panel pivot assembly, and the top end is coupled to the top of the frame 41 via a positioning assembly. A handle 7 is provided on the panel 42. The handle 7 is preferably made of silicone or soft rubber, which is soft and easy to fold.

[0052] like Figure 11As shown, the top of the frame 41 abuts against the inner side of the frame 15 of the top panel 1. A first stopper is provided on the panel 14, corresponding to the top of the frame 41, to prevent the frame 41 from moving or collapsing. This first stopper is a first stopper rib 12 formed on the inner side of the panel 14. This first stopper rib 12 has a first hook 13 formed on it. The outer side of this first hook 13 forms a first blocking surface 131, and the inner side forms a first inclined guide surface 132. When the frame 41 and the top panel 1 are in the deployed position (perpendicular to each other), the first blocking surface 131 abuts against the inner edge of the top of the frame 41, thereby limiting and supporting the rear panel 3 and enhancing the stability of the structure. During assembly, the first inclined guide surface 132 guides the top of the frame 41 between the first hook 13 and the frame 15, allowing the first stopper 131 to abut against the inner edge of the top of the frame 41, thereby achieving a perpendicular position between the rear panel 3 and the top panel 1.

[0053] At the same time, the left side plate 5 is provided with a second limiting portion near the frame 41 for limiting the side of the frame 41 to prevent the frame 41 from moving or collapsing. The second limiting portion is a second limiting rib 52 formed on the inner side of the left side plate 5. A second hook 53 is formed on the second limiting rib 52. The outer side of the second hook 53 forms a second blocking surface 531, and the inner side forms a second inclined guide surface 532. Figure 11 As shown, when the frame 41 and the left side panel 5 are in the expanded state (perpendicular to each other), the second blocking surface 531 abuts against the side edge of the frame 41, thereby limiting and supporting the frame 41 and enhancing the stability of the structure. The second inclined guide surface 532 can guide the frame 41 into the position between the second hook 53 and the edge of the left side panel 5 during assembly, so that the second blocking surface 531 abuts against the side edge of the frame 41, forming a perpendicular position between the frame 41 and the left side panel 5.

[0054] In this embodiment, the positioning component at the top of the panel 42 is a magnetic component, which includes a first magnetic block provided on the panel and a second magnetic block provided on the frame 41, and the first magnetic block and the second magnetic block attract each other. Figure 11 As shown, a first mounting position 421 is formed at the top of the panel 42, and a second mounting position 411 is formed at a corresponding position on the frame 41. A first magnetic block is fixed in the first mounting position 421, and a second magnetic block is fixed in the second mounting position 411. By pulling the handle 7, the attraction between the first and second magnetic blocks is overcome, and the panel 42 can be rotated outward, opening the panel 42, allowing the user to place items inside the cabinet. In actual situations, the positioning components can also be used as mutually interlocking snap components.

[0055] The bottom ends of the left side plate 5 and the right side plate 6 are respectively rotatably arranged on both sides of the bottom plate 2 through the side wall rotating assembly, and the side wall rotating assembly has a first rotating seat 21 and a first rotating shaft 54, as shown in FIG. Figure 12 As shown, the first rotating seat 21 is formed on the bottom plate 2 and has coaxially arranged first rotating holes 211 on both sides; Figure 5 As shown, taking the left side plate 5 as an example, a first slot 55 is provided at the bottom end of the left side plate 5 corresponding to the first rotating seat 21, and coaxially arranged first rotating shafts 54 are formed on opposite sides of the first slot 55. The two first rotating shafts 54 extend into the two first rotating holes 211 respectively to realize the rotation connection between the left side plate 5 and the bottom plate 2. Figure 12 As shown, the first rotation hole 211 is further provided with a first notch 212 on the side (upper side) facing the left side panel 5, allowing the first rotation shaft 54 ​​to engage with the first rotation hole 211 from top to bottom. The first rotation seat 21 and the two first rotation shafts 54 together form a side wall rotation assembly. In this embodiment, a pair of side wall rotation assemblies are respectively provided between the left and right side panels 5, 6, and the base 2. The number of side wall rotation assemblies can be selected based on the actual dimensions of the left and right side panels 5, 6, and base 2 to ensure a relatively stable structure.

[0056] The bottom end of the rear panel 3 is rotatably arranged at the rear bottom of the bottom panel 2 through the rear wall rotating assembly. The rear wall rotating assembly has a similar structure to the above-mentioned side wall rotating assembly. Specifically, the rear wall rotating assembly has: a second rotating seat 22 and a second rotating shaft 32. Figure 12 As shown, the second rotating seat 22 is formed on the bottom plate 2 and has coaxially arranged second rotating holes 221 on both sides; Figure 11 As shown, the bottom end of the rear plate 3 is provided with a second slot 31 corresponding to the second rotating seat 22, and the second slot 31 is formed with coaxially arranged second rotating shafts 32 on opposite sides. The two second rotating shafts 32 extend into the two second rotating holes 221 respectively to realize the rotation connection between the rear plate 3 and the bottom plate 2. Figure 12 As shown, the second rotation hole 221 is further provided with a second notch 222 on the side (upper side) facing the rear panel 3, for the second rotation shaft 32 to engage with the second rotation hole 221 from top to bottom. The aforementioned second rotation seat 22 and two second rotation shafts 32 together form a rear wall rotation assembly. In this embodiment, four rear wall rotation assemblies are respectively disposed between the rear panel 3 and the base 2. The number of rear wall rotation assemblies can be selected based on the actual size of the rear panel 3 and the base 2 to ensure a relatively stable structure.

[0057] The bottom end of the frame 41 is rotatably arranged at the front bottom of the bottom plate 2 through the front wall rotating assembly. The front wall rotating assembly has a similar structure to the above-mentioned side wall rotating assembly. Specifically, the front wall rotating assembly has: a third rotating seat 23 and a third rotating shaft 43, as shown in FIG. Figure 13As shown, the third rotating seat 23 is formed on the bottom plate 2 and has coaxially arranged third rotating holes 231 on both sides; Figure 11 As shown, the bottom end of the frame 41 is provided with a third slot 44 corresponding to the third rotating seat 23, and coaxially arranged third rotating shafts 43 are formed on opposite sides of the third slot 44. The two third rotating shafts 43 extend into the two third rotating holes 231 respectively to realize the rotation connection between the frame 41 and the bottom plate 2. Figure 13 As shown, the third rotation hole 231 has a third notch 232 on the side (upper side) facing the frame 41, allowing the third rotation shaft 43 to engage with the third rotation hole 231 from top to bottom. The third rotation seat 23 and the two third rotation shafts 43 together form a front wall rotation assembly. In this embodiment, four front wall rotation assemblies are respectively disposed between the frame 41 and the base 2. The number of front wall rotation assemblies can be selected based on the actual size of the frame 41 and base 2 to ensure a relatively stable structure.

[0058] The height of the rotation axis of the above-mentioned side wall rotation assembly (that is, the height of the first rotation hole 211 and the first rotation axis 54) is h1, the height of the rotation axis of the rear wall rotation assembly (that is, the height of the second rotation hole 221 and the second rotation axis 32) is h2, and the height of the rotation axis of the front wall rotation assembly (that is, the height of the third rotation hole 231 and the third rotation axis 43) is h3, wherein h1>h2>h3, and the height difference between h2 and h1 is close to the edge thickness of the rear panel 3, and the height difference between h3 and h2 is close to the edge thickness of the frame 41, so that when folded, the side panel, the rear panel 3 and the front panel 4 can be stacked together in sequence to form a folded shape. Figure 7 The status shown.

[0059] The frame 41 and the bottom of the panel 42 are connected by a panel rotating assembly. Figures 9-11 As shown, the panel rotation assembly includes a central rotation group 45 and a side rotation group 46. The central rotation group 45 has a central rotation seat 451 formed at the bottom end of the frame 41 and a central rotation shaft 452 formed on the panel 41. The central rotation seat 451 has a C-shaped central opening 453 for the central rotation shaft 452 to be inserted into on one side facing the inside of the cabinet. A socket 454 is formed between the central rotation shaft 452 and the panel 42 for the upper edge of the C-shaped central opening 453 to be inserted into. Figure 11 As shown, the upper edge of the middle opening 453 is protruded toward the side where the middle shaft 452 is located to form a guide limit protrusion 455, which is used to abut against the middle shaft 452 to ensure the stability of the middle shaft 452 being stuck in the middle opening 453. Figure 9As shown, the side rotation group 46 has a side rotation hole 461 opened on the side of the frame 41 and a side rotation shaft 462 formed on the side of the panel 42. A side opening 463 for the side rotation shaft to be inserted is opened on one side of the side rotation hole 461, and the middle opening 453 and the side opening 463 are in opposite directions, the middle opening 453 faces inside the cabinet, and the side opening 463 faces outside the cabinet, so that both the inside and outside of the panel 42 can be supported and limited, further improving the stability of the structure.

[0060] like Figure 12 and Figure 13 As shown, the edge of the bottom plate 2 protrudes upward to form a rim 24, and the first rotating seat 21, the second rotating seat 22 and the third rotating seat 23 are formed on the inner side of the rim 24, so that when the cabinet is spliced ​​together, the two side panels, the back panel 3 and the bottom end of the frame 41 are all wrapped in the rim 24, as shown in FIG. Figure 1 As shown, this design can make the cabinet more stable. The height of the edge 24 where the first rotating seat 21 is located is higher than the height of the edge 24 where the third rotating seat 23 is located. This is because the front plate 4 is composed of a frame 41 and a panel 42. In order to enable the panel 42 to be opened and laid flat, the connection between the middle rotating seat 451 and the middle rotating shaft 452 is set to a structure exposed to the edge 24, so the height of the edge 24 here is lower. Figure 14 As shown, when the panel 42 is opened and laid flat, the edge can also be combined with the frame 41 to support the panel 42, so that some lighter items can be placed on the panel 42 when it is laid flat.

[0061] When this embodiment is folded, Figure 4 As shown, first push the top end of the front panel 4 into the cabinet to disengage it from the first hook 13, and then rotate and fold it so that the front panel 4 is stacked on the bottom panel 2; then push the top end of the back panel 3 into the cabinet to disengage it from the first hook 13, and rotate and fold it toward the inside of the cabinet so that the back panel 3 is stacked on the front panel 4; then push the top ends of the left side panel 5 and the right side panel 6 into the cabinet to disengage them from the first hook 13, and finally press down the top panel 1, the upper ends of the left side panel 5 and the right side panel 6 will slide along the slide groove portion 11 on the top panel 1, and the lower ends will rotate toward the inside of the cabinet, so that the left side panel 5 and the right side panel 6 are folded until they are stacked on the back panel 3. At the same time, the top panel 1 is covered on the folded side panels, back panel 3 and front panel 4, and finally a Figure 3 On the contrary, when the cabinet needs to be assembled, the top plate 1 is first pulled upwards, the upper ends of the left side plate 5 and the right side plate 6 will slide along the slide groove 11 on the top plate 1, and the lower ends are rotated and unfolded toward the outside of the cabinet. The top ends are embedded in the first hook 13 under the action of the first inclined guide surface 132, so that the left side plate 5 and the right side plate 6 are rotated to the vertical state, and then the rear plate 3 and the front plate 4 are flipped outwards to the vertical state to complete the assembly, forming a cabinet as shown.
