Description

Technical Field

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

[0002] Storage boxes create independent, enclosed spaces and are common household storage tools for storing clothing, shoes, books, and documents. Pull-out storage boxes have a pull-out structure for easy access to items. However, pull-out boxes typically have a non-foldable drawer structure, making them inconvenient to store, taking up considerable space during transport, and prone to damage from bumps and knocks. Some technologies disassemble pull-out storage boxes into multiple sections, requiring users to assemble them piece by piece upon receipt. While the process is simple, it's highly repetitive, and the more boxes there are, the longer it takes. When users need to transport or store the boxes later due to moving, they must disassemble them, repeating the assembly process for future use. This is tedious and time-consuming, and parts or sections are easily lost during disassembly, rendering the storage box useless. Utility Model Content

[0053] It should be noted that, for ease of description, the side of the folding storage box that faces the user when it is in normal use is called the front side, and the opposite side is called the back side; the left and right sides are distinguished by the direction the user faces when the folding storage box is in normal use; and the top and bottom are distinguished by the top and bottom sides of the folding storage box when it is in normal use.

[0054] like Figures 1 to 3 As shown in the figure, a folding storage box 100 of this utility model embodiment has a folded state and an unfolded state. The folding storage box 100 includes a bottom plate 110, a top plate 120, a pull-out plate 130, a door panel assembly 150, a back plate 160 and at least two side panel assemblies 140.

[0055] Specifically, the top plate 120 and the bottom plate 110 are arranged opposite to each other. A pull-out plate 130 is located on the side of the bottom plate 110 facing the top plate 120 and is connected to the bottom plate 110. The pull-out plate 130 can move relative to the bottom plate 110 in the front-back direction. For example, as... Figure 1As shown, the base plate 110 has a mounting hole 113 extending in the front-rear direction. A limiting strip 117 is provided on the side wall of the mounting hole 113 extending in the front-rear direction, and the limiting strip 117 has a mounting notch 118. The bottom side of the pull-out plate 130 has an L-shaped limiting block 133. One end of the limiting block 133 is connected to the bottom surface of the pull-out plate 130, so that a U-shaped limiting groove is formed between the limiting block 133 and the bottom surface of the pull-out plate 130. The end of the limiting block 133 away from the pull-out plate 130 can move from the upper side of the base plate to the lower side of the base plate through the mounting notch 118, so that the limiting strip 117 can be embedded in the limiting groove, so that the pull-out plate 130 is connected to the base plate 110. When the pull-out plate 130 moves in the front-rear direction relative to the base plate 110, the limiting groove slides along the limiting strip 117 to limit the pull-out plate. When it is necessary to disassemble the pull-out plate 130 and the base plate 110, move the pull-out plate 130 relative to the base plate 110 to the position where the limiting block 133 is opposite to the mounting notch 118, move the pull-out plate 130 upward, and the end of the limiting block 133 away from the pull-out plate 130 moves upward through the mounting notch 118 and disengages from the limiting strip 117.

[0056] The top end of the side panel assembly 140 is rotatably connected to the top panel 120, and the bottom end of the side panel assembly 140 is rotatably connected to the bottom panel 110. The side panel assembly 140 is foldable so that its top and bottom ends are close to each other. The door panel assembly 150 is rotatably connected to the top panel 120, and the back panel 160 is rotatably connected to the top panel 120. The side panel assembly 140, door panel assembly 150, and back panel 160 are distributed circumferentially along the top panel, wherein the door panel assembly 150 is located on the front side of the top panel 120, the back panel 160 is located on the rear side of the top panel 120, the side panel assembly 140 is located between the door panel assembly 150 and the back panel 160, and at least one side panel assembly 140 is located on the left side of the top panel 120, and at least one side panel assembly 140 is located on the right side of the top panel 120.

[0057] When the folding storage box 100 is in the unfolded state, the door panel assembly 150 and the back panel 160 abut against the bottom plate 110 to support the top plate 120. A first storage space 111 is formed between the top plate 120 and the bottom plate 110. The side panel assembly 140, the door panel assembly 150, and the back panel 160 constitute the sidewalls of the first storage space 111. In some embodiments, when the folding storage box 100 is in the unfolded state, the door panel assembly 150 is connected to the unfolded side panel assembly 140 to fix the side panel assembly 140 and prevent the side panel assembly 140 from folding during use. For example, the door panel assembly 150 and the side panel assembly 140 can be engaged by a snap-fit.

[0058] When the folding storage box 100 is in the folded state, the top plate 120 and the bottom plate 110 abut against each other, forming a second storage space 115 between them. The side plate assembly 140 rotates into the second storage space 115 and folds in, and the door panel assembly 150 and the back panel 160 also rotate into the second storage space 115. The height of the folding storage box 100 is reduced, making it easier to store and transport. Furthermore, in the folded state, the side plate assembly 140, the door panel assembly 150, the back panel 160, and the pull-out panel 130 can all be stored in the second storage space 115, preventing any parts of the folding storage box 100 from being missing.

[0059] like Figure 1 As shown, the folding storage box 100 is in the unfolded state, and the pull-out panel 130 can hold items. The pull-out panel 130 includes a panel 132 and a handle 131. The user can operate the pull-out panel 130 to move relative to the base plate 110 through the handle 131. Figure 1 In the example, the plate 132 is completely located within the first storage space 111, and the plate 132 forms the bottom of the first storage space 111, while at least a portion of the handle 131 is located outside the storage space 111. Figure 2 As shown, the folding storage box 100 is in the unfolded state, and the pull-out panel 130 moves forward relative to the bottom plate 110 away from the first storage space 111, so that part of the panel 132 is located outside the first storage space 111, so as to bring the items out of the storage space 111 for easy access by the user. Compared with the existing drawer structure storage box, the pull-out panel 130 is thinner and occupies less space. The top plate 120 and the bottom plate 110 can be close to each other to reduce the height of the folding storage box 100 and to fold the folding storage box 100 for storage.

[0060] The upper end of the side panel assembly 140 is rotatably connected to the top plate 120, and the lower end is rotatably connected to the bottom plate 110. This allows the side panel assembly 140 to fold over through relative rotation between the sub-panels and between the sub-panels and the top and bottom plates 120, bringing the bottom plate 110 and top plate 120 closer together, thereby compressing and folding the storage box 100. The sub-panel connected to the top plate 120 is the first sub-panel 141, and the sub-panel connected to the bottom plate 110 is the second sub-panel 142.

[0061] Side panel assembly 140, door panel assembly 150, and back panel 160 are distributed circumferentially along the storage space 111. When the folding storage box 100 is in the unfolded state, the side panel assembly 140, door panel assembly 150, and back panel 160 constitute the sidewalls of the first storage space 111. The back panel 160 and door panel assembly 150 are arranged opposite each other. For example, the door panel assembly 150 is located on the front side of the storage space 111, and the back panel 160 is located on the rear side of the storage space 111. When the folding storage box 100 is in the unfolded state, the bottom end of the door panel assembly 150 abuts against the bottom plate 110, and the bottom end of the back panel 160 abuts against the bottom plate 110 to support the top plate 120 and the bottom plate 110 to form a stable first storage space 111. When the folding storage box 100 is in the folded state, there is a second storage space 115 between the bottom plate 110 and the top plate 120, which can accommodate the pull-out panel 130, the door panel assembly 150, the back plate 160, and the side panel assembly 140. The door panel assembly 150, the back plate 160, and the side panel assembly 140 are all connected to the top plate 120 and rotate relative to the top plate 120 and are stored in the second storage space 115. The bottom plate 110 and the top plate 120 are connected through the side panel assembly 140, thereby preventing the loss of parts during the folding storage box 100 during storage and transportation. The second storage space 115 also serves to store and protect the pull-out panel 130, the door panel assembly 150, the back plate 160, and the side panel assembly 140 from being squeezed and damaged.

[0062] The folding storage box 100 according to this utility model embodiment uses a pull-out panel 130 to hold items, avoiding contact with the top panel 120 and bottom panel 110. The top panel 120 and bottom panel 110 can be brought close together to reduce the height of the folding storage box 100 and facilitate folding. The side panel assembly 140 is rotatably connected to the top panel 120 and bottom panel 110 respectively and can be folded. The door panel assembly 150 and back panel 160 are rotatably connected to the top panel 120 respectively. Thus, the folding storage box 100 can be folded or unfolded by rotating and folding the side panel assembly 140 and by rotating the door panel assembly 150 and back panel 160, saving installation steps and maintaining the connection between the various components of the folding storage box 100 after folding, preventing the loss of components during transportation or after prolonged periods of non-use. Furthermore, when the folding storage box 100 is in the folded state, there is a second storage space 115 between the bottom plate 110 and the top plate 120, which can accommodate the pull-out panel 130, the door panel assembly 150, the back panel 160 and the side panel assembly 140. This space serves to store and protect the pull-out panel 130, the door panel assembly 150, the back panel 160 and the side panel assembly 140 from being squeezed and damaged. It also ensures that the folded storage box 100 has a neat appearance after folding, making it convenient for transportation.

[0063] In some embodiments, the side panel assembly 140 includes at least two sub-panels rotatably connected in sequence. The sub-panel located at the top of the side panel assembly 140 is a first sub-panel 141, which is rotatably connected to the top panel 120. The sub-panel located at the bottom of the side panel assembly 140 is a second sub-panel 142, which is rotatably connected to the bottom panel 110. Both the first sub-panel 141 and the second sub-panel 142 can rotate between the top panel 120 and the bottom panel 110 to fold the side panel assembly 140. Thus, the side panel assembly 140 can be folded by the relative rotation between the sub-panels and between the sub-panels and the top panel 120 and the bottom panel 110, bringing the bottom panel 110 and the top panel 120 closer together, thereby compressing and folding the storage box 100. In the folded state, both the first sub-panel 141 and the second sub-panel 142 rotate into the second storage space.

[0064] Taking the side panel assembly 140, which includes two sub-panels, as an example, Figure 2 As shown, the first sub-plate 141 is located above the second sub-plate 142. The first sub-plate 141 is rotatably connected to the top plate 120, and its rotating shaft extends in the front-rear direction. The second sub-plate 142 is rotatably connected to the bottom plate 110, and its rotating shaft extends in the horizontal direction. The first sub-plate 141 and the second sub-plate 142 are rotatably connected, and their rotating shafts extend in the horizontal direction. Figure 11 As shown in the figure, the folding storage box 100 is in the process of folding. When the folding storage box 100 is folded, the first sub-plate 141 and the second sub-plate 142 both rotate into the storage space 111, the top plate 120 and the bottom plate 110 move closer to each other, and the height of the storage space 111 decreases. Figure 3 and Figure 6 As shown in the figure, the folding storage box 100 is in a folded state, and the side panel assembly 140 is stored in the storage space 111. The sub-panels are rotatably connected to the top panel 120 and the bottom panel 110 by hinges or pivots, and the sub-panels are rotatably connected to each other by hinges or pivots.

[0065] According to some embodiments of this utility model, the bottom side of the top plate 120 is provided with a first connecting part 122 and a second connecting part 124. When the folding storage box 100 is in the folded state, the door panel assembly 150 is connected to the first connecting part 122 to limit the position of the door panel assembly 150 in the vertical direction, and the back plate 160 is connected to the second connecting part 124 to limit the position of the back plate 160 in the vertical direction. On the one hand, during the folding or unfolding of the folding storage box 100, the position of the door panel assembly 150 is limited by the first connecting part 122, and the position of the back plate 160 is limited by the second connecting part 124, preventing the door panel assembly 150 and the back plate 160 from flipping downwards and affecting operation; on the other hand, it can prevent the door panel assembly 150 and the back plate 160 from flipping downwards and falling off in the folded state, thus preventing them from squeezing the pull-out plate 130 and the side panel assembly 140. Figure 11As shown in the figure, the folding storage box 100 is in the process of folding and storing. The door panel assembly 150 is connected to the first connecting part 122, and the back panel 160 is connected to the second connecting part 124, thereby limiting the position of the door panel assembly 150 and the back panel 160 in the vertical direction during the folding process.

[0066] Specifically, the door panel assembly 150 is rotatably connected to the top panel 120. When the folding storage box 100 is folded, the door panel assembly 150 can move to a first position relative to the top panel 120. At the first position, the bottom end of the door panel assembly 150 is close to the top panel 120, and the door panel assembly 150 is connected to the first connecting part 122. For example, the first connecting part 122 can be a buckle. After the door panel assembly 150 rotates upward 90° relative to the top panel 120, it can be fastened to the first connecting part 122. When the folding storage box 100 is in the folded state, the door panel assembly 150 is stored in the second storage space 115. The connection between the door panel assembly 150 and the first connecting part 122 can prevent the door panel assembly 150 from rotating or falling downward during or after folding. It should be noted that the first connecting part 122 is staggered from the connection position of the top plate 120 and the door panel assembly 150 to ensure that the door panel assembly 150 can prevent the door panel assembly 150 from rotating relative to the top plate 120 after it is connected to the first connecting part 122.

[0067] The back panel 160 is rotatably connected to the top panel 120. When the folding storage box 100 is folded, the back panel 160 can rotate relative to the top panel 120 to a second position. In this second position, the bottom end of the back panel 160 is close to the top panel 120, and the back panel 160 is connected to the second connecting part 124. This allows the back panel 160 to be stored in the second storage space 115 when the folding storage box 100 is folded. The connection between the back panel 160 and the second connecting part 124 prevents the back panel 160 from rotating relative to the top panel 120 or falling downwards during or after folding. It should be noted that the connection positions of the second connecting part 124 and the top panel 120 and back panel 160 are staggered to ensure that the connection between the back panel 160 and the second connecting part 124 prevents the back panel 160 from rotating relative to the top panel 120.

[0068] like Figure 4 and Figure 5As shown, the first connecting portion 122 has a fixing groove 123 extending in the front-to-back direction. When the folding storage box 100 is in the folded state, the door panel assembly 150 is located within the fixing groove 123. Specifically, the upper end of the door panel assembly 150 is rotatably connected to the top plate 120, and the connection position between the top plate 120 and the door panel assembly 150 is located at the end of the fixing groove 123 away from the storage space 111. When the door panel assembly 150 is folded for storage, the door panel assembly 150 first flips upward relative to the top plate 120 to a third position, so that the door panel assembly 150 is located outside the first storage space 111 and parallel to the fixing groove 123. Then, the door panel assembly 150 is pushed to slide along the fixing groove 123 into the first storage space 111, so that the left and right edges of the door panel assembly 150 are embedded in the fixing groove 123. The fixing groove 123 supports the door panel assembly 150 to limit the position of the door panel assembly 150 in the vertical direction.

[0069] like Figures 13 to 15 As shown, in some embodiments, the front end of the fixing groove 123 is provided with a fastening block 126. The fastening block 126 forms an arc-shaped surface on the side facing the first storage space 111, and the arc-shaped surface is smoothly connected to the lower side wall of the fixing groove 123. The upper end of the door frame 151 is provided with a semi-circular connector 1511, and the side of the door frame 151 facing the first storage space 111 may be provided with a groove extending vertically. When the folding storage box 100 is in the unfolded state, the connector 1511 is fastened to the fastening block 126 and fits against the arc-shaped surface of the fastening block 126. When the door panel assembly 150 is flipped upward, the connector 1511 rotates along the arc-shaped surface until the door panel assembly 150 is parallel to the fixing groove 123, which can push the door panel assembly 150 into the first storage space 111. During the sliding of the door panel assembly 150 along the fixing groove 123, the door frame 151 slides along the fixing groove 123, and the fastening block 126 is embedded in the groove of the door frame 151 and slides relative to the groove, thereby limiting the door frame 151.

[0070] like Figure 4As shown, according to some embodiments of the present invention, a first surrounding plate 121 is provided on the bottom side of the top plate 120. The first surrounding plate 121 extends circumferentially along the top plate 120, and a first connecting portion 122 is provided on the inner side of the first surrounding plate 121. When the folding storage box 100 is in the folded state, the first surrounding plate 121 at least constitutes part of the side wall of the second storage space 115. Specifically, the first surrounding plate 121 has a certain height. After the folding storage box 100 is folded, the first surrounding plate 121 is located between the top plate 120 and the bottom plate 110, and abuts against the bottom plate 110, so that a second storage space 115 capable of storing the side panel assembly 140, the door panel assembly 150, and the back plate 160 is left between the top plate 120 and the bottom plate 110. The side of the first surrounding plate 121 facing the first storage space 111 or the second storage space 115 is the inner side of the first surrounding plate 121. Figure 5 As shown, the first connecting portion 122 includes an upper stiffening plate 1221 and a lower stiffening plate 1222 spaced apart vertically. Both the upper and lower stiffening plates 1221 and 1222 are located on the side of the first enclosure 121 facing the storage space 111, and a fixing groove 123 is formed between them. To improve the supporting strength of the first connecting portion 122, at least one reinforcing rib 1223 may be provided on the lower side of the lower stiffening plate 1222. In some embodiments, there are two first connecting portions 122, respectively located on the left and right sides of the first enclosure 121 of the top plate 120.

[0071] like Figure 2 and Figure 3 As shown, in some embodiments, a second surrounding plate 114 is provided on the side of the bottom plate 110 facing the top plate 120. The second surrounding plate 114 extends along the circumferential direction of the bottom plate 110. When the folding storage box 100 is in the folded state, the first surrounding plate 121 abuts against the second surrounding plate 114 to form a second storage space 115 between the top plate 120 and the bottom plate 110. The first surrounding plate 121 and the second surrounding plate 114 constitute the sidewalls of the second storage space 115. In some embodiments, a fixing groove 123 may also be formed on the second connecting portion 124. After the back plate 160 is flipped to the second position, it can slide along the fixing groove 123 for storage. The specific structure of the second connecting portion 124 can be referred to the first connecting portion 122, and will not be described again here.

[0072] According to some embodiments of this utility model, the door panel assembly 150 includes a door frame 151, a first door panel 152, and a second door panel 153. The door frame 151 is rotatably connected to the top plate 120. The first door panel 152 and the second door panel 153 are distributed in the door frame 151 in a left-right direction. The first door panel 152 and the second door panel 153 are rotatably connected to the door frame 151, and the pivots of rotation of the first door panel 152 relative to the door frame 151 and the pivots of rotation of the second door panel 153 relative to the door frame 151 both extend in a vertical direction. When the folding storage box 100 is unfolded for normal use, the first door panel 152 and the second door panel 153 can rotate relative to the door frame 151 to open the folding storage box 100, and the pull-out plate 130 can move in a front-back direction between the first door panel 152 and the second door panel 153. When the folding storage box 100 is folded, both the first door panel 152 and the second door panel 153 rotate into the door frame 151, and the door frame 151 flips upward relative to the top plate 120 so that the door panel assembly 150 rotates to the first position. In some embodiments, the first door panel 152 and the second door panel 153 can be limited to prevent them from rotating downward after the door panel assembly 150 rotates to the first position. For example, a limiting protrusion can be provided on the side of the door frame 151 facing the storage space 111 to block the first door panel 152 and the second door panel 153; or a damping ring can be provided at the connection between the first door panel 152, the second door panel 153 and the door frame 151 to increase the rotational resistance of the first door panel 152 and the second door panel 153. Figure 1 As shown, when the first door panel 152 and the second door panel 153 are folded into the door frame 151, the first door panel 152 and the second door panel 153 block the door frame 151 to separate the storage space 111 from the outside of the folding storage box 100. At this time, a through hole is formed between the first door panel 152 and the second door panel 153, and the handle 131 of the pull-out plate 130 extends out of the storage space 111 through the through hole.

[0073] like Figures 7 to 10 As shown, according to some embodiments of the present invention, the back panel 160 is provided with a third connecting portion 161. When the folding storage box 100 is in the folded state, the third connecting portion 161 is connected to the second connecting portion 124. Specifically, the top end of the back panel 160 is rotatably connected to the top plate 120. The back panel 160 is flipped upward relative to the top plate 120 to a second position, so that the back panel 160 is located on the bottom side of the top plate 120, thereby connecting the second connecting portion 124 and the third connecting portion 161. In some embodiments, the second connecting portion 124 and the third connecting portion 161 are snap-fitted together. For example, as... Figure 10As shown, both the second connecting part 124 and the third connecting part 161 are snap-fit ​​structures. The ends of the second connecting part 124 and the third connecting part 161 are respectively provided with protrusions. After the back plate 160 rotates to the second position, the protrusions of the second connecting part 124 and the protrusions of the third connecting part 161 face each other and interlock. Of course, the structure of the second connecting part 124 and the third connecting part 161 is not limited to this. For example, one of the second connecting part 124 and the third connecting part 161 can be a through hole, and the other can be a connecting post with elastically deformable ends, the ends of which elastically deform to pass through the through hole for connection.

[0074] like Figure 10 As shown, according to some embodiments of the present invention, the second connecting part 124 is disposed on the first enclosure 121 and located on the inner side of the first enclosure 121, so as to avoid interference between the second connecting part 124 and the items in the storage space 111, and to prevent the second connecting part 124 from scratching the user's hand when the user reaches into the storage space 111, thereby improving safety.

[0075] According to some embodiments of this utility model, the first connecting portion 122 and the second connecting portion 124 are staggered in the vertical direction so that when the folding storage box 100 is in the folded state, the door panel assembly 150 and the back panel 160 are staggered in the vertical direction, avoiding interference between the door panel assembly 150 and the back panel 160. For example, as Figure 5 and Figure 10 As shown, the second connecting part 124 is located on the bottom side of the lower stiffener 1222 of the first connecting part 122. When the folding storage box 100 is in the folded state, the door panel assembly 150 is located on the upper side of the back panel 160 to avoid interference between the two.

[0076] like Figure 1 and Figure 3 As shown, according to some embodiments of the present invention, one of the top side of the top plate 120 and the bottom side of the bottom plate 110 is provided with a limiting protrusion 125, and the other is provided with a limiting groove 112, wherein the limiting protrusion 125 and the limiting groove 112 are adapted to each other. Figure 12 As shown, when two or more folding storage boxes 100 are stacked vertically, the limiting protrusion 125 of the lower folding storage box 100 is located within the limiting groove 112 of the upper folding storage box 100, thereby limiting the two adjacent folding storage boxes 100 in the horizontal direction and improving stability. Figure 4 and Figure 8 As shown, in some embodiments, the folding storage box 100 also includes a baffle 116, which is connected to the front side wall of the base plate 110 and can cover the gap formed by the excessive height of the front side wall of the base plate 110, making the appearance of the folding storage box 100 flatter and more beautiful.

[0077] like Figure 4 and Figure 6 As shown, an embodiment of this utility model provides a storage box assembly, comprising at least two folding storage boxes 100 stacked vertically as described above. Any two adjacent folding storage boxes 100 are designated as a first folding storage box and a second folding storage box, respectively. The bottom plate 110 of the first folding storage box and the top plate 120 of the second folding storage box are integrally formed to form a connecting plate 170. The bottom side of the connecting plate 170 constitutes the top wall of the first storage space 111 and the second storage space 115 of the second folding storage box, while the top side of the connecting plate 170 constitutes the bottom wall of the first storage space 111 and the second storage space 115 of the first folding storage box. This design allows for a more stable connection between the multiple folding storage boxes 100, and also enables simultaneous operation of multiple folding storage boxes 100 during folding or unfolding, saving time. In some embodiments, the top plate 120 of the folding storage box 100 located at the top of the storage box group is provided with a limiting protrusion 125 on the top side, and the bottom plate 110 of the folding storage box 100 located at the bottom of the storage box group is provided with a limiting groove 112 on the bottom side, so as to limit the storage box group when it is stacked with other storage box groups or with a single folding storage box 100.

[0078] The working process of this utility model is as follows:

[0079] When the folding storage box 100 needs to be folded and stored, the pull-out plate 130 is pushed into the first storage space 111 for storage. The door panel assembly 150 is flipped upward to the first position and pushed along the fixing groove 123, so that the door panel assembly 150 is stored between the bottom plate 110 and the top plate 120. The back panel 160 assembly is flipped upward to the second position, so that the back panel 160 is located between the bottom plate 110 and the top plate 120, and the third connecting part 161 is connected to the second connecting part 124, thereby fixing the back panel 160. Then, the first sub-plate 141 and the second sub-plate 142 of the side panel assembly 140 are rotated between the bottom plate 110 and the top plate 120, respectively. The first sub-plate 141 and the second sub-plate 142 rotate relative to each other, so that the side panel assembly 140 is folded between the bottom plate 110 and the top plate 120. The top plate 120 and the bottom plate 110 are close to each other, the first enclosure 121 and the second enclosure 114 abut against each other, and a second storage space 115 is formed between the bottom plate 110 and the top plate 120. The height of the folding storage box 100 is reduced, making it convenient for storage and transportation.

[0080] When the folding storage box 100 needs to be unfolded for use, the first sub-plate 141 and the second sub-plate 142 are rotated outwards, causing the side panel assembly 140 to unfold and the top plate 120 and the bottom plate 110 to move away from each other. Then, the second connecting part 124 and the third connecting part 161 are separated, and the back plate 160 is flipped downwards so that the bottom end of the back plate 160 abuts against the bottom plate 110; the door panel assembly 150 is pulled out from the fixing groove 123, and the door panel assembly 150 is flipped downwards so that the bottom end of the door panel assembly 150 abuts against the bottom plate 110 to support the top plate 120 and the bottom plate 110. It should be emphasized that, since the door panel assembly 150 is connected to the first connecting part 122 and the third connecting part 161 is connected to the second connecting part 124, when the door panel assembly 150 and the back panel 160 are stored in the storage space 111, they can be stably connected to the top panel 120, preventing the door panel assembly 150 or the back panel 160 from flipping downwards, thus avoiding affecting the user's folding or unfolding operations, and preventing the door panel assembly 150, the back panel 160 assembly from being squeezed by the side panel assembly 140 and the pull-out panel 130.

[0081] The unfolding and folding process of the storage box assembly can refer to the operation process of the single folding storage box 100 described above. During the operation, the top plate 120 and bottom plate 110 of multiple folding storage boxes 100 can be squeezed or stretched simultaneously to move closer or further apart.

[0082] In summary, this utility model embodiment provides a folding storage box 100 and a storage box assembly, which makes folding and unfolding operations more convenient. Furthermore, since no parts need to be disassembled, the probability of parts being lost or the folding storage box 100 malfunctioning during storage and transportation is significantly reduced. In addition, the connection between the first connecting part 122 and the second connecting part 124 ensures that when the door panel assembly 150 and the back panel 160 are stored in the storage space 111, they can be securely connected to the top panel 120, preventing the door panel assembly 150 or the back panel 160 from accidentally flipping downwards, thus avoiding interference with the user's folding or unfolding operations. It also prevents the door panel assembly 150 and the back panel 160 from being squeezed against the side panel assembly 140 and the pull-out panel 130.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit it. It should be pointed out that those skilled in the art can make several improvements and substitutions without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
