[0065] Furthermore, unless otherwise defined, the technical and scientific terms used in this invention have the same meanings as commonly understood by one of ordinary skill in the art. The terminology used in this invention is for the purpose of describing particular embodiments only and not for limiting the invention. It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or collections thereof.

[0066] Example 1: As Figures 1-12As shown, a folding structure includes a rear panel 1 and two sets of side panels mounted on the rear panel 1. The rear panel 1 has U-shaped seats 101 on both sides. Each side panel includes a first side panel 201 and a second side panel 202, which are respectively mounted on the two sets of U-shaped seats 101. The lengths of both the first and second side panels are less than or equal to the width of the rear panel 1. When the side panels are folded towards the rear panel 1, both the first and second side panels 201 are located between the two sets of U-shaped seats 101. By using the rear panel 1 as the storage base, folding can be achieved even when the shorter side of the base plate 3 needs to be longer than the height of the side panels. By limiting the relationship between the lengths of the first and second side panels 201 and the width of the rear panel 1, it is ensured that the two sets of side panels are completely located between the two sets of U-shaped seats 101 during folding, compressing the storage volume. Furthermore, the folding order of the two sets of side panels is unrestricted, improving usability.

[0067] The first side plate 201 is provided with a first rotating part 29 protruding towards the rear plate 1. The first rotating part 29 includes a first mounting post 5 and a set of U-shaped seats 101 with a recessed groove 4. The first mounting post 5 is slidably mounted in the recessed groove 4. Through the sliding assembly design of the first mounting post 5 and the recessed groove 4, the first side plate 201 can be folded and moved into the interior of the U-shaped seat 101 to prevent the second side plate 202 from getting stuck with the first side plate 201 when it is folded.

[0068] The first rotating part 29 also includes a first movable column 30. The U-shaped seat 101 has a first movable groove 31. The first movable groove 31 and the recessed groove 4 are located on the same side. The first movable column 30 is slidably assembled in the first movable groove 31. The sliding assembly of the first movable column 30 and the first movable groove 31 makes the movement of the folded first side plate 201 in the U-shaped seat 101 more stable.

[0069] The first movable groove 31 has a first limiting protrusion 32 on the side wall near the first rotating part 29. The first limiting protrusion 32 is used to limit the first movable column 30. The setting of the first limiting protrusion 32 improves the assembly stability of the first side plate 201 and the U-shaped seat 101, and prevents the first movable column 30 from moving out of the first movable groove 31 when it is restored to the unfolded state, which would cause the structure to loosen.

[0070] Two sets of first limiting protrusions 32 are provided and are arranged opposite to each other on the side wall of the first movable groove 31. The assembly stability of the first side plate 201 and the U-shaped seat 101 is further improved by the two sets of first limiting protrusions 32 arranged opposite to each other.

[0071] The first side panel 201 includes a first folding plate 203 and a third folding plate 205 hinged to the first folding plate 203. The first rotating part 29 is disposed on the third folding plate 205. By dividing the first side panel 201 into two folding plates that are hinged to each other, the length of the first side panel 201 can be significantly increased, which makes it easier to increase the storage space on the side where the first side panel 201 is located before folding.

[0072] The first folding plate 203 has a first connecting part 33 protruding towards the rear plate 1. The first connecting part 33 has two sets of first rotating holes 34. The third folding plate 205 has a first connecting groove 35 that is adapted to the first connecting part 33. The top and bottom walls of the first connecting groove 35 are both provided with first rotating shafts 36. The first rotating shafts 36 are rotatably assembled in the first rotating holes 34. By assembling the two sets of first rotating shafts 36 in the upper and lower sets of first rotating holes 34, the rotational stability of the first folding plate 203 and the third folding plate 205 is improved.

[0073] The first connecting part 33 and the first connecting groove 35 are each provided in two sets and are distributed on the upper and lower sides of the first side plate 201. By providing two sets of rotating structures, the rotational stability of the first folding plate 203 and the third folding plate 205 is further improved.

[0074] The first folding plate 203 is provided with a first mating groove 37 on the same side as the first connecting part 33. The first mating grooves 37 are distributed at intervals on the upper and lower sides of the first connecting part 33. The third folding plate 205 is provided with a first mating protrusion 38 on the same side as the first connecting groove 35. The first mating protrusion 38 is connected to the first mating groove 37. Through the mating arrangement of the first mating groove 37 and the first mating protrusion 38, a buffering force is provided when the first folding plate 203 and the third folding plate 205 rotate, thereby improving the stability of the rotating structure.

[0075] The second side plate 202 has a second rotating part 39 protruding towards the rear plate 1. The second rotating part 39 includes a second mounting post 28. Another set of U-shaped seats 101 has a recessed hole 27. The second mounting post 28 is rotatably assembled with the recessed hole 27. By rotatably assembling the second mounting post 28 with the recessed hole 27, the second side plate 202 can be folded and fixed to the outside of the first side plate 201 to prevent the first side plate 201 from shifting outward, thereby preventing the folding structure from loosening.

[0076] The second rotating part 39 also includes a second movable column 40. The U-shaped seat 101 has a second movable groove 41. The second movable groove 41 and the sink hole 27 are located on the same side. The second movable column 40 is rotatably assembled in the second movable groove 41. The rotational assembly of the second movable column 40 and the second movable groove 41 makes the rotation of the folded second side plate 202 in the U-shaped seat 101 more stable.

[0077] The second movable groove 41 has a second limiting protrusion 42 protruding on the side wall near the second rotating part 39. The second limiting protrusion 42 is used to limit the second movable column 40. The setting of the second limiting protrusion 42 improves the assembly stability of the second side plate 202 and the U-shaped seat 101, and prevents the second movable column 40 from rotating out of the second movable groove 41 in the restored unfolded state, which would cause the structure to loosen.

[0078] Two sets of second limiting protrusions 42 are provided and are arranged opposite to each other on the side wall of the second movable groove 41. The assembly stability of the second side plate 202 and the U-shaped seat 101 is further improved by the two sets of second limiting protrusions 42 arranged opposite to each other.

[0079] The second side panel 202 includes a second folding plate 204 and a fourth folding plate 206 hinged to the second folding plate 204. The second rotating part 39 is disposed on the fourth folding plate 206. By dividing the second side panel 202 into two folding plates that are hinged to each other, the length of the second side panel 202 can be significantly increased, which makes it easier to increase the storage space on the side where the second side panel 202 is located before folding.

[0080] The second folding plate 204 has a second connecting part 43 protruding towards the rear plate 1. The second connecting part 43 has a second rotating hole 44. The fourth folding plate 206 has a second connecting groove 45 that is adapted to the second connecting part 43. The top and bottom walls of the second connecting groove 45 are both provided with a second rotating shaft 46. The second rotating shaft 46 is rotatably assembled in the second rotating hole 44. By assembling the second rotating shaft 46 in the upper and lower sets of second rotating holes 44, the rotational stability of the second folding plate 204 and the fourth folding plate 206 is improved.

[0081] The second connecting part 43 and the second connecting groove 45 are each provided in two sets and are distributed on the upper and lower sides of the second side plate 202. By providing two sets of rotating structures, the rotational stability of the second folding plate 204 and the fourth folding plate 206 is further improved.

[0082] The second folding plate 204 is provided with a second mating groove 47 on the same side as the second connecting part 43. The second mating grooves 47 are distributed at intervals on the upper and lower sides of the second connecting part 43. The fourth folding plate 206 is provided with a second mating protrusion 48 on the same side as the second connecting groove 45. The second mating protrusion 48 is connected to the second mating groove 47. The mating of the second mating groove 47 and the second mating protrusion 48 provides a buffer force when the second folding plate 204 and the fourth folding plate 206 rotate, thereby improving stability.

[0083] It also includes a base plate 3 rotatably connected to the bottom wall of the rear plate 1. The bottom of the side plate has an inward protrusion with a first fastener 6. The two sides of the base plate 3 are provided with first fastening grooves 7. The first fastener 6 and the first fastening grooves 7 are engaged and assembled. The quick assembly and disassembly between the side plate and the base plate 3 are achieved through the cooperation of the first fastener 6 and the first fastening grooves 7.

[0084] The sum of the thicknesses of the first side plate 201, the second side plate 202, and the base plate 3 is less than or equal to the length of the U-shaped seat 101. By limiting the ratio of the sum of the thicknesses of the first side plate 201, the second side plate 202, and the base plate 3 to the length of the U-shaped seat 101, it is ensured that the layers of panels fit tightly after folding, thus optimizing space utilization.

[0085] Among them, the sum of the thicknesses of the first folding plate 203, the second folding plate 204, the third folding plate 205, the fourth folding plate 206 and the base plate 3 is less than or equal to the length of the U-shaped seat 101. By limiting the ratio of the sum of the thicknesses of the first folding plate 203, the second folding plate 204, the third folding plate 205, the fourth folding plate 206 and the base plate 3 to the length of the U-shaped seat 101, it is ensured that the layers of plates fit tightly after folding, thus optimizing space utilization.

[0086] The height of the back panel 1 is greater than or equal to the width of the back panel 1. By adopting the design that the height of the back panel 1 is greater than the width, the vertical support stability is enhanced, and the higher back panel 1 can provide a larger effective vertical storage space.

[0087] The length of the base plate 3 is less than or equal to the height of the back plate 1. By adopting the design that the length of the base plate 3 is less than or equal to the height of the back plate 1, the base plate 3 can be completely stored outside the back plate 1 when folded, avoiding outward protrusion and ensuring that the overall structure after folding is a regular cuboid or cube, which is convenient for transportation and storage.

[0088] Example 2: Figures 1-17 As shown, a folding storage box includes a folding structure as described in Embodiment 1, and also includes a front panel 10. The inner walls on both sides of the front panel 10 are provided with second snap-fit ​​grooves 9. A second snap-fit ​​member 8 is protruding on the side of the side panel away from the rear panel 1. The second snap-fit ​​member 8 is snapped into the second snap-fit ​​groove 9. The snap-fit ​​connection between the front panel 10 and the side panel is achieved through the cooperation of the second snap-fit ​​member 8 and the second snap-fit ​​groove 9, which facilitates the quick assembly and disassembly of the two.

[0089] The system also includes a top plate 11, and a first mounting protrusion 12 protruding upward on the top wall of the side plate. The inner walls on both sides of the top plate 11 are provided with first mounting grooves 13. The first mounting protrusion 12 is mounted in the first mounting grooves 13. The top plate 11 and the side plate are stably assembled through the cooperation and connection of the first mounting protrusion 12 and the first mounting grooves 13.

[0090] The side panel has a second assembly groove 14 on its outer top wall and a first assembly part 17 hinged to the side wall of the second assembly groove 14. The top panel 11 has a third assembly groove 15 on its outer side wall and a second assembly protrusion 16 protruding from the outer wall of the third assembly groove 15. The second assembly protrusion 16 is engaged with the first assembly part 17. The engagement of the hinged first assembly part 17 and the second assembly protrusion 16 achieves a snap-fit ​​connection between the side panel and the top panel 11, further improving the assembly stability and disassembly flexibility between the side panel and the top panel 11.

[0091] The front plate 10 has a first protrusion 18 on its top wall and a fifth assembly groove 21 on its inner wall. The first protrusion 18 is assembled in the fifth assembly groove 21 to achieve stable assembly between the top plate 11 and the front plate 10.

[0099] Example 4: Including the folding storage box from Example 2, this example provides a specific implementation of a folding storage box, with the following design dimensions for storing tall items:

[0100]

[0101] In this embodiment, the rear plate 1 is used as the storage base. To achieve a greater degree of folding functionality, when storing taller items, the size of the base plate 3 only needs to be set according to the actual length and width of the items. For example, to store an item with a size of (40*30*60) cm3, this embodiment only needs to set the size to (40*30*60) cm3 under extreme conditions. However, existing folding storage boxes are limited by using the base plate 3 as the storage base. To achieve the folding function, both the width and length must be greater than or equal to the height, that is, at least (60*60*60) cm3 is required. This results in some storage space being wasted. Therefore, this embodiment is suitable for storing taller items without wasting space.

[0102] The implementation principle of a folding storage box is as follows: When the folding storage box is folded, the user first flips the first assembly 17 outward to disassemble it from the second assembly protrusion 16. Then, the user sequentially separates the first protrusion 18 from the fifth assembly groove 21, the second protrusion 20 from the seventh assembly groove 23, and the first assembly protrusion 12 from the first assembly groove 13, thereby disassembling the top plate 11 from the front plate 10, the rear plate 1, and the side plate. Then, the user separates the second buckle 8 and the second buckle groove 9, thereby disassembling the front plate 10 from the side plate. Then, the user removes the first buckle 6 from the first buckle groove 7, thereby disassembling the side plate and the bottom plate 3. Then, the user folds the bottom plate 3 upward inside the rear plate 1. Then, the user folds the first folding plate 203 and the third folding plate 205 inward to fold the first side plate 201 into the rear plate 1. The first assembly post 5 is along the U-shaped seat 101 in the rear plate 1. The recessed groove 4 slides inward to the outside of the folded bottom plate 3. The first movable column 30 moves in the first movable groove 31 to abut against the first limiting protrusion 32. Then, the second folding plate 204 and the fourth folding plate 206 are folded inward, and the second side plate 202 is folded into the outside of the first side plate 201. The second assembly column 28 rotates in the recessed hole 27, thereby completing the folding process of the box. When the folding storage box is unfolded, the user first folds the second folding plate 204 and the fourth folding plate 206 outward, then unfolds the second side plate 202 to be perpendicular to the rear plate 1. Then, the first folding plate 203 and the third folding plate 205 are folded outward, and the first side plate 201 is unfolded to be perpendicular to the rear plate 1. Then, the bottom plate 3 is unfolded outward, and its two sides are snapped together with the first side plate 201 and the second side plate 202. Then, the front plate 10 and the top plate 11 are installed in sequence to complete the unfolding process of the box.
