[0028] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. Among them, the detachable mounting mode has many kinds, for example, it can be matched by plug-in and buckle, and for example, it can be connected by bolts and the like.

[0029] The present application will be described in more detail below with reference to specific embodiments, but the embodiments of the present application are not limited thereto, and the embodiments are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application. For process parameters or conditions not specifically mentioned, conventional techniques can be referred to.

[0030] Please refer to Figures 1-7 The technical scheme adopted in the present embodiment is: a foldable storage box, comprising: a box body 1, comprising a bottom 11, a top 12, a side wall blocking assembly 13 and a cover 14, the side wall blocking assembly 13 comprising a plurality of side wall blocking parts distributed circumferentially around the bottom 11; a crease structure 6 connected between the bottom 11 and each of the side wall blocking parts, between the top 12 and at least one side wall blocking part, and between the cover 14 and the top 12, and switching the box body 1 between the unfolded state and the folded state by bending; a restraint assembly 3 comprising at least one restraint member 31, the restraint member 31 being connected to the box body 1 and being fixed by a detachable connecting structure 32 to constrain the box body 1 in the folded state.

[0031] In the present embodiment, PP hollow plate is used as the substrate 8, and cloth 9 is used to wrap the bottom 11, the top 12, the side wall blocking assembly 13 and the cover 14. The components are fixed by sewing thread, thereby forming the crease structure 6 on the cloth 9, so that the box body 1 can be bent at a predetermined angle in the unfolded and folded states. In addition, the restraint assembly 3 is installed outside the box body 1, and the restraint member 31 can be a strap, which is passed through the perforations provided on each side wall blocking part and then fixed by the detachable connecting structure 32, thereby forming a closed fixed path in the folded state to ensure that the components are tightly combined without loosening. However, the closed fixed path formed by the restraint assembly 3 effectively prevents the box body 1 from loosening or accidentally unfolding when folding; moreover, the storage box can be unfolded into a flat shape, greatly saving storage and transportation space; and the crease structure 6 ensures smooth and reliable conversion between unfolding and folding.

[0032] It should be noted that the crease structure 6 can be replaced by a punched groove or a flexible pivot scheme instead of a sewing line; the fixing method of the constraint member 31 can be replaced by a buckle or magnetic attraction assembly instead of a magic tape; the substrate material can also be selected from PET, EVA and other hard and environmentally friendly materials.

[0033] The crease structure 6 is one of a sewing line, a punched groove or a flexible pivot; in this embodiment, the crease structure 6 is formed on the cloth 9 by using a sewing line fixing method, but a V-shaped or U-shaped groove can also be made on the substrate 8 by using a punching method, or a flexible pivot can be used to realize the bending between components to achieve the same folding effect. However, different technical solutions can flexibly meet the production process requirements to ensure that the products under each scheme can realize stable folding and recovery; the sewing line scheme is simple and low-cost, while the punching or pivot is suitable for mass production to improve consistency.

[0034] It should be noted that according to the production equipment conditions and product positioning, the user can freely select or combine one or more of the above three methods.

[0035] The crease structure 6 is a sewing line, and the bottom 11, the top 12, the side wall blocking assembly 13 and the cover 14 all include a substrate 8 and a cloth 9 wrapped around the substrate 8; in this embodiment, all the components of the box body 1 use PP hollow plates as substrates 8 and are covered with corresponding cloths 9. The connection between each component is fixed by sewing, that is, after aligning each substrate 8, sewing along the contact edge of the two substrates 8, a crease is formed on the cloth 9, thereby forming a crease on the surface of the cloth 9, realizing the bending function in the folding process. The composite structure ensures the combination of rigidity and flexibility, thereby realizing smooth folding and unfolding; and the crease fixed by the sewing line makes the product easy to operate and has high durability in repeated use.

[0036] It should be noted that the substrate material can be replaced by other hard plastics; and the style and color of the wrapping cloth 9 can be adjusted according to user needs and market positioning.

[0037] The detachable connection structure 32 includes a first connecting member and a second connecting member, the first connecting member is arranged on one free end of the constraint member 31, the second connecting member is arranged on the other free end of the constraint member 31, and the first connecting member and the second connecting member are detachably connected. The first connecting member can be the hook surface or the hair surface of the magic tape, the second connecting member can be the hair surface or the hook surface of the magic tape, and the first connecting member and the second connecting member are fixed by magic tape adhesion. The detachable connection structure 32 can also be a buckle or a magnetic attraction assembly, and the first connecting member is a buckle male head or a magnetic attraction piece, and the second connecting member is a buckle female head or a magnetic attraction piece.

[0038] In this embodiment, the constraint member 31 can be a strap, and two free ends of the strap are respectively provided with a first connecting member and a second connecting member. Here, a magic tape connection mode is adopted, that is, one end is a magic tape hook surface, and the other end is a magic tape fluff surface. The constraint member 31 is fixed by using the self-adhesive function of the magic tape to achieve connection and disassembly, so as to ensure that the components of the box body 1 are reliably combined when the box body 1 is folded. The connection mode is simple to operate and quick to disassemble and assemble, and meets the needs of users to flexibly switch between the folded and unfolded states. After being fixed, the constraint member 31 can be firmly fixed in the folded state to prevent the structure from being loose.

[0039] It should be noted that, in addition to the magic tape, other modes such as buckles, magnetic attraction, plug-in buckles, or pressing buckles can be used to achieve detachable fixing to adapt to the fixing strength requirements in different occasions.

[0040] The outer surface of the first connecting member or the second connecting member is provided with a replaceable pattern layer 33, and the pattern layer 33 is used to display the category identification of the items in the storage box. In this embodiment, in order to enhance the product personalization function, the outer surface of the first or second connecting member provided on the constraint member 31 is provided with a pattern layer 33. When the user replaces the items in the box, the pattern layer 33 can be replaced with a pattern matching the current item category to intuitively display the content information. The design of the pattern layer 33 not only improves the appearance of the product, but also facilitates the user to quickly identify the category of the items in the box. The replaceable pattern layer 33 scheme enables the product to have certain intelligent prompting function, thereby enhancing the market competitiveness. It should be noted that the pattern layer 33 can be realized by color printing, laser engraving, or film technology. Moreover, a detachable magnetic pattern piece can also be used to facilitate frequent replacement and update of information.

[0041] The side wall blocking assembly 13 includes a first side wall blocking part 131 distributed on the left side of the bottom 11, a second side wall blocking part 132 distributed on the right side of the bottom 11, and a third side wall blocking part 133 distributed on the rear side of the bottom 11. The constraint member 31 passes through the through hole of the third side wall blocking part 133 and extends to the through holes of the first side wall blocking part 131 and the second side wall blocking part 132 to form a closed fixing path around the circumference of the box body 1.

[0042] In this embodiment, the side wall blocking assembly 13 is divided into at least three parts: the first side wall blocking part 131 on the left side of the bottom 11, the second side wall blocking part 132 on the right side of the bottom 11, and the third side wall blocking part 133 on the rear side of the bottom 11. The constraint member 31, for example, a strap, passes through the through hole of the third side wall blocking part 133 and extends to the through holes of the first side wall blocking part 131 and the second side wall blocking part 132, thereby forming a complete closed fixing path on the side of the box body 1 to constrain the box body 1 in the folded state to keep close combination. Thus, the closed fixing path can effectively keep the components of the box body 1 from being separated in the folded state, thereby ensuring the stability of the whole. This structure is simple in arrangement and easy to manufacture, and can improve the fixing effect of the product.

[0043] It should be noted that the position and number of the perforations can be optimized according to the size and fixing requirements of the box body 1; the material and fixing method of the constraint member 31 can be adjusted according to the use environment, such as selecting high-strength fibers or elastic materials.

[0044] The outer side of the first side wall blocking part 131, the second side wall blocking part 132 and the third side wall blocking part 133 is provided with a cover 4, and a cavity is formed between the cover 4 and the corresponding side wall blocking part, and a first perforation 41 and a second perforation 42 are arranged on each cover 4 in an interval manner; the free end of the constraint member 31 is inserted into the cavity from the first perforation 41 of the cover 4 of the first side wall blocking part 131, and then is inserted into the first perforation 41 and the second perforation 42 of the cover 4 of the second side wall blocking part 132 and the third side wall blocking part 133 in sequence, so that the insertion path of the constraint member 31 is hidden in the cavity.

[0045] In the embodiment, the cover 4 is fixed on the outer side of the first side wall blocking part 131, the second side wall blocking part 132 and the third side wall blocking part 133, and the cover 4 and the side wall blocking part form a cavity through sewing connection. Each cover 4 is provided with two perforations, i.e., a first perforation 41 and a second perforation 42, which are arranged on opposite edges of the cover 4 along the length direction. The constraint member 31 is inserted from the perforation of the third side wall blocking part 133, and then is inserted through the perforations of the covers 4 of the first side wall blocking part 131 and the second side wall blocking part 132, i.e., is inserted through the first perforation 41 and the second perforation 42 of each corresponding cover 4, to form a closed path which is mainly hidden in the cavity. Thus, most of the path of the constraint member 31 is hidden in the cavity, the exposed part is reduced, the overall appearance is improved, the reasonable perforation layout ensures the tightness of the fixing path, and thus the stability of the box body 1 in the folded state is enhanced, and the fixing effect is optimized. The hidden design of the constraint member 31 effectively reduces the risk of external wear and tear, prolongs the service life, and reduces the possibility of loosening or falling off of the constraint member 31 caused by external force, thereby playing a protection role. The overall appearance and durability of the product are improved, and the product is suitable for the positioning of high-end household products.

[0046] It should be noted that the material of the cover 4 in the embodiment is cloth, but it is not limited thereto, and the cover 4 can also be made of transparent PVC or other decorative materials, so as to improve the visual effect, which can be determined according to requirements; in addition, the cover 4 can also be replaced by a sliding rail, a guide belt groove or other fixing structures; the constraint member 31 can also be arranged in a storage bag hidden in the bottom 11 or the internal cavity. In addition, the number and distribution of the perforations can be adjusted and optimized according to the actual size.

[0047] The perforation is embedded with a protective ring 5, which is made of metal or hard plastic; in this embodiment, all perforations are embedded with protective rings 5, which are made of ABS hard plastic or metal and are installed on the inner side edge of the perforation through press-fitting or injection molding process to ensure that the restraint member 31 will not wear or damage the perforation when passing through; and the protective ring 5 greatly improves the tensile strength of the perforation to ensure structural stability during long-term use; at the same time, it makes the edge of the perforation smooth, effectively reduces the wear of the restraint member 31, is not easy to be torn, and prolongs the service life of the product.

[0048] It should be noted that stainless steel or aluminum alloy protective rings 5 can be selected to enhance strength according to actual needs; or an integral injection molding structure can be used to avoid later assembly. In addition, the installation method of the protective ring 5 can be changed to threaded fixing or buckle type installation for easy future maintenance, disassembly or replacement.

[0049] The side wall blocking assembly 13 further includes a fourth side wall blocking part 134 distributed on the front side of the bottom 11, and the fourth side wall blocking part 134 and the cover body 14 are connected through a crease structure 6 to enable the cover body 14 and the fourth side wall blocking part 134 to realize flexible rotation; in this embodiment, in order to further improve the overall closing and rotating function of the folding storage box, the side wall blocking assembly 13 is extended designed, that is, the fourth side wall blocking part 134 is arranged on the front side of the bottom 11. In specific implementation, the fourth side wall blocking part 134 adopts the same manufacturing process as other side wall blocking parts, that is, the base plate 8 is composed of hard plate material such as PP hollow plate, and is covered with cloth 9 to ensure both rigidity and the required flexibility.

[0050] In this embodiment, the fourth side wall blocking part 134 and the cover body 14 are connected through a crease structure 6. Specifically, at the connection area of the fourth side wall blocking part 134 and the cover body 14, the base plate 8 of the fourth side wall blocking part 134 is aligned with the base plate 8 of the cover body 14, and then the two are sewn along the contact edge to form a crease on the cloth 9, which enables the cover body 14 to produce flexible rotation relative to the fourth side wall blocking part 134 during folding. This flexible rotation enables the cover body 14 and the fourth side wall blocking part 134 to remain closely attached when the box body 1 is folded or unfolded, thereby realizing the flat closing and conversion of the entire box body 1. By arranging the fourth side wall blocking part 134 on the front side of the bottom 11 and connecting it with the cover body 14 through the crease structure 6, the natural attachment of each part in the folded state is realized, further improving the overall integrated and aesthetic effect of the box body 1.

[0051] It should be noted that in addition to using a sewing line to form a crease on the cloth 9, a V-shaped or U-shaped groove can also be machined on the base plate 8 through a stamping process, or a flexible rotating shaft can be used to realize the flexible connection between the fourth side wall blocking part 134 and the cover body 14. Each method can be flexibly selected according to production process and cost requirements.

[0052] At least part of the edges of the box body 1 is provided with an edge covering structure 7 for covering the edges; specifically, the edge covering structure 7 is a flexible edge covering layer which covers the edges of the hard plate and is fixed by sewing or gluing; in the unfolded state, all edges of the box body 1 are provided with the edge covering structure 7; which can include the edges of the bottom 11, the top 12, the side wall blocking assembly 13 and the cover 14.

[0053] In the present embodiment, the box body 1 uses a PP hollow plate as the hard substrate 8, and each component constitutes the final product after being covered by cloth 9. In order to prevent the edges of the hard plate from affecting the appearance or safety of the product due to sharpness or wear during long-term use, in the unfolded state of the box body 1, the edges of all the outer periphery are covered with the edge covering structure 7.

[0054] In a specific implementation, the edge covering structure 7 uses a flexible edge covering layer, such as nylon tape, which covers the edges of the box body 1 and is fixed on the plate by sewing or gluing. This process can ensure that the edge covering layer is tightly attached and plays a protective role for the edges, while providing a smooth touch and preventing scratches on the user. The edge covering layer is continuously distributed along the periphery of the box body 1 in the finished product, maintaining the consistency of the overall appearance and making the product look more delicate in the unfolded state. However, the edge covering structure 7 not only protects the edges of the hard plate from environmental damage, but also reduces the wear and tear caused by external friction on the box body 1, helping to extend the service life of the product; the fixing method of the edge covering structure 7: the edge covering layer can be fixed by sewing, gluing, heat sealing or high-frequency welding, and the specific fixing method can be adjusted according to the production process conditions. It should be noted that although in the present embodiment, the entire periphery of the box body 1 in the unfolded state is provided with the edge covering structure 7, it is also possible to only cover specific areas, such as areas with high touch frequency or areas prone to damage, in order to reduce costs and meet specific design requirements.

[0055] In addition, in order to enhance the firmness of the combination between the first side wall blocking part 131 and the second side wall blocking part 132 and the edge covering structure 7, one side of the substrate 8 of the first side wall blocking part 131 on the left and the second side wall blocking part 132 on the right is embedded in the inner side of the edge covering structure 7 of the edge of the bottom 11, specifically: one side of the substrate 8 of the first side wall blocking part 131 and the second side wall blocking part 132 is inserted into the U-shaped groove formed by the edge covering structure 7 of the left and right edges of the bottom 11, and is fixed by sewing thread. In this way, not only is the combination of the substrate 8 and the edge covering structure 7 firm, but also the edge part of the entire box body 1 in the unfolded state appears smoother and more beautiful.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments, and other embodiments obtained by the skilled in the art without creative labor based on the embodiments of the utility model all fall within the protection scope of the utility model. In addition, all the connection relationships mentioned in the text do not mean that the components are directly connected, but that a better connection structure can be formed by adding or reducing connection auxiliary components according to the specific implementation situation.
