Description

Technical Field

[0001] This utility model relates to the field of storage devices, and in particular to a portable mobile storage device. Background Technology

[0002] In the field of baby products, portable baby storage boxes can store baby bottles, clothes, diapers and other baby supplies. They are equipped with a carrying strap so that parents can easily take them from home to the outdoors or to the car. Existing portable baby storage boxes are generally divided into two categories. One type of storage box uses sturdy materials for all parts, focusing on support and user experience, while the other type uses soft materials for all parts and can be folded for storage. However, both types of products have their own shortcomings.

[0003] Baby storage boxes made of rigid materials offer advantages such as structural stability and strong support, allowing for the storage of heavier items without the bottom collapsing or getting damaged. They also maintain an upright position, preventing side collapse and making it easier and more convenient to place and retrieve items without interference from the sides. However, these products are not foldable. For users, they occupy fixed space when not in use, and their volume cannot be compressed. For manufacturers, the packaging and transportation volume is large, with most of the volume being wasted, resulting in high packaging and transportation costs.

[0004] Baby product storage boxes designed with all-soft materials have the advantage of being able to be folded for storage when not in use, and significantly reducing packaging and transportation costs; however, they have problems such as difficulty in keeping upright, side collapse hindering use, poor support capacity, and easy deformation.

[0005] Currently, the market is basically dominated by two types of products. One type is storage boxes made of thick felt, which are more supportive than other soft materials. The other type is storage boxes with folding structures, such as hinges, while maintaining a sturdy material. Although these products have solved the above problems to some extent, they have also created new problems such as increased costs. Summary of the Invention

[0006] To address the aforementioned technical problems, this utility model provides a portable mobile storage device, comprising a base plate and an enclosure. The enclosure consists of at least three side supports that enclose the base plate, with at least two being variable supports. Each variable support includes a vertical plate and a flexible outer casing. The outer casing has an opening and closing structure to allow the vertical plate to move in and out. When the vertical plate is inside the outer casing, it can support the outer casing, allowing the enclosure to stand upright on the base plate, forming an open storage space at the top. After the vertical plate is removed, the flexible outer casing folds the enclosure onto the base plate. The device switches between states by assembling and disassembling the vertical plate: when supported by the vertical plate, it presents a three-dimensional storage form; when unsupported, it becomes a flat, folded form. This facilitates storage and transportation, significantly reduces the space occupied when not in use, and features a simple structure and high portability.

[0007] The technical solution of this utility model is implemented as follows: A portable mobile storage device includes a base plate with an enclosure connected to it. The enclosure includes at least three side supports that enclose the base plate along its contour. At least two of the side supports are variable supports. Each variable support includes a vertical plate and a flexible outer casing covering the vertical plate. The outer casing has an opening and closing structure configured such that opening the structure allows the outer casing to open, enabling the vertical plate to enter or leave the outer casing. When the vertical plate is inside the outer casing, it supports the flexible outer casing, causing the enclosure to stand upright on the base plate, forming a storage space for placing items between the base plate and the enclosure. When the vertical plate leaves the outer casing, the flexibility of the outer casing allows the enclosure to fold onto the base plate.

[0008] The enclosure is a closed-loop structure, with its lower end connected to the base plate and closed, while its upper end remains open for users to place items. During transport, the base plate needs to support these items; therefore, the base plate is rigid compared to the flexible outer casing. Within the enclosure, the vertical panels of the variable support are detachable, meaning they can be inserted into or removed from the outer casing. Thus, the variable support has two variable states: a flexible state and a rigid state. In the rigid state, the vertical panels are located within the outer casing to support it, keeping the entire storage device upright and preventing collapse. When all the side supports on the base plate are upright, because their outer casings are... The components are connected, thus maintaining the overall upright position of the enclosure on the base plate. In the flexible state, the uprights are located outside the outer casing, and the outer casing regains its flexibility. As a result, the other side supports cannot be restricted or supported and cannot remain upright. Therefore, the side supports collapse onto the base plate to achieve folding, reducing the volume of the storage device. In this solution, the storage device forms a box, container, or basket for storage through the support provided by each upright in the three-dimensional direction. The outer casing is the receiver of the three-dimensional support. When the three-dimensional support is lost, the flexibility of the outer casing causes the other side supports to fall down, thereby allowing the enclosure to fold onto the base plate, reducing the space occupied by the storage device.

[0009] When the variable support is supported in three dimensions, the storage device is three-dimensional. When the three-dimensional support is lost, the storage device changes from three-dimensional to a relatively flat surface and loses its storage space.

[0010] Preferably, each side support includes at least a vertical plate, and the lower edge of the enclosure is connected to the base plate. The inclusion of a vertical plate in each side support ensures the enclosure can stand upright.

[0011] Preferably, each side support includes an outer casing covering the vertical plate; the base plate includes a support plate and an outer casing covering the support plate, with the outer casing of the base plate connected to the outer casing of the side supports. The enclosure of the enclosure is achieved through the outer casing, that is, the connection between the side supports is achieved through the connection of the outer casing. The vertical plate is the supplier of the three-dimensional support, and the outer casing is the receiver of the three-dimensional support. At the same time, the connection between the outer casings causes each side support to influence each other. Therefore, the outer casing is also a linkage for state switching. When the outer casing receives three-dimensional support, each side support can remain upright. When the outer casing loses three-dimensional support, neither side support can remain upright (the outer casing without the vertical plate becomes soft, collapses, and deforms, and the side support still with the vertical plate loses support and falls down), thus realizing the switching between use and folding of the storage device; the outer casing is made of a flexible material, such as flexible fabric, which can maintain the consistency of the appearance of the storage device and facilitate sewing connections.

[0012] Preferably, the base plate is rectangular, and the enclosure includes four side supports. One set of opposing side supports are variable supports, and the other set of opposing side supports are closed supports. When the upright plate of the variable support detaches from the outer casing, the two closed supports can fall towards each other and rest against the base plate. When the base plate is rectangular, once the two opposing variable supports lose their three-dimensional support, the closed supports also lose their lateral support and cannot remain upright, falling over in an upright posture. Regardless of the shape of the base plate, the folding of this solution cannot be achieved when the closed supports are two adjacent side supports.

[0013] Preferably, the base plate is rectangular, with two long sides and two short sides. Variable supports are side supports located on the two long sides, and closed supports are side supports located on the two short sides. The length of the long sides is greater than or equal to twice the height of the side supports. When the uprights are removed from the outer casing, the two closed supports fall towards each other and each abuts against the base plate. In this design, the folding mechanism is more efficient, as the two closed supports cannot overlap, resulting in a folded thickness that is only the thickness of the base plate plus the thickness of a single closed support. Even after folding and then adding the removed uprights, the overall thickness remains relatively thin.

[0014] Preferably, the base plate is rectangular, with two long sides and two short sides. The variable supports are side supports located on the two short sides, and the closed supports are side supports located on the two long sides. When the uprights are removed from the outer casing, the two closed supports fall towards each other and stack sequentially on the base plate. In this design, the assembly and disassembly of the uprights in the variable supports are more convenient because the overall dimensions of the uprights are smaller.

[0015] A portable mobile storage device includes a flexible body comprising at least four outer casings: a bottom outer casing and at least three side outer casings surrounding the bottom outer casing. Each outer casing contains a panel. The bottom outer casing and at least one side outer casing have opening and closing structures configured such that opening the structures allows the corresponding outer casing to open, enabling the panel to enter or leave the corresponding outer casing. When all panels are within the outer casings, the side outer casings stand upright on the bottom outer casing, forming a storage space for placing items between the bottom and side outer casings. The bottom outer casing is located at the bottom to support the items. When the panel leaves the bottom outer casing and the side outer casing with the opening and closing structure, the side outer casing without the opening and closing structure can be folded closed. This solution is another way to achieve folding of portable mobile storage devices. It mainly involves removing the plates of the bottom outer casing and the side outer casing, so that the remaining two side outer casings and their plates can move relative to each other. These two side outer casings and their plates can achieve close folding by rotating or moving closer to each other. Even if the plates in multiple side outer casings cannot be removed, they can still be folded after multiple movements.

[0016] Preferably, the opening and closing structure includes an opening and a switch structure disposed at the opening. The outer casing is a layered structure with at least two flexible layers and a receiving space for accommodating the upright plate is formed between the different flexible layers. The opening is disposed on the outer casing and communicates with the receiving space. The switch structure is configured to control the opening to open or close. When the opening is open, the receiving space is open. When the opening is closed, the receiving space is closed.

[0017] Preferably, the switch structure is a Velcro structure, a snap structure, or a button structure.

[0018] Preferably, the opening is located on the side of the outer casing, and the outer contour of the outer casing is closed by stitches, with the stitches breaking at the opening.

[0019] The design starting point, concept, and beneficial effects of this utility model, which adopts the above technical solution, are as follows: The enclosure is a closed-loop structure. Its lower end is connected to the base plate and then closed, while its upper end remains open for users to place items. During transportation, the base plate needs to support these items, so the base plate is rigid compared to the flexible outer casing. In the enclosure, the vertical plates of the variable support are detachable and can be installed inside or removed from the outer casing. Therefore, the variable support has two variable states: a flexible state and a rigid state. In the rigid state, the vertical plates are located in the outer casing to support it, thus keeping the entire storage device upright and preventing it from collapsing. When all the side supports on the base plate are upright, since their outer casings are connected, the enclosure as a whole can remain upright on the base plate. In the flexible state, the uprights are located outside the outer casing. The outer casing regains its flexibility, and the other side supports are therefore unable to be restricted or supported, and also cannot remain upright. As a result, the side supports fall onto the base plate to achieve folding, reducing the volume of the storage device. In this solution, the storage device forms a box, container, or basket for storage through the support provided by each upright in the three-dimensional direction. The outer casing is the receiver of the three-dimensional support. When the three-dimensional support is lost, the flexibility of the outer casing causes the other side supports to fall down, thereby allowing the enclosure to fold onto the base plate. That is, when the variable support is supported in the three-dimensional direction, the storage device is three-dimensional; when the three-dimensional support is lost, the storage device changes from three-dimensional to a relatively flat surface and loses its storage space.

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0024] In the description of this utility model, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] The specific embodiments of this utility model are as follows: Example

[0026] like Figure 1-8 As shown, this utility model provides a portable mobile storage device, including a base plate 1, with an enclosure 2 connected to the base plate 1. The enclosure 2 includes at least three side supports 3 that enclose the base plate 1 along its contour. At least two of the side supports 3 are variable supports 31. Each variable support 31 includes a vertical plate 4 and a flexible outer casing 5 covering the vertical plate 4. The outer casing 5 is provided with an opening and closing structure 6, which is configured such that when the opening and closing structure 6 is opened, the outer casing 5 is open, allowing the vertical plate 4 to enter or leave the outer casing 5. When the vertical plate 4 is inside the outer casing 5, the vertical plate 4 supports the flexible outer casing 5, causing the enclosure 2 to stand upright on the base plate 1, forming a storage space 7 for placing items between the base plate 1 and the enclosure 2. When the vertical plate 4 leaves the outer casing 5, the flexibility of the outer casing 5 allows the enclosure 2 to fold onto the base plate 1.

[0027] like Figure 2-5 As shown, the enclosure 2 is a closed-loop structure. Its lower end is connected to the base plate 1 and closed, while its upper end remains open for users to place items. During transport, the base plate 1 needs to support these items, so it is rigid compared to the flexible outer casing 5. In the enclosure 2, the upright plate 4 of the variable support 31 is detachable, meaning it can be inserted into or removed from the outer casing 5. Therefore, the variable support 31 has two variable states: a flexible state and a rigid state. In the rigid state, the upright plate 4 is located within the outer casing 5 to support it, thus keeping the entire storage device upright and preventing collapse. When all the side supports 3 on the base plate 1 are upright, since their outer casings 5 ​​are connected, the enclosure 2 remains upright on the base plate 1. In its normal state, the upright plate 4 is located outside the outer casing 5, and the outer casing 5 regains its flexibility. As a result, the other side supports 3 cannot be restricted or supported, and they also cannot remain upright. Therefore, the side supports 3 fall onto the base plate 1 to achieve folding, thereby reducing the volume of the storage device. In this solution, the storage device forms a box, container, or basket for storage by being supported in the three-dimensional direction by each upright plate 4. The outer casing 5 is the receiver of the three-dimensional support. When the three-dimensional support is lost, the flexibility of the outer casing 5 causes the other side supports 3 to fall down, thereby allowing the enclosure 2 to fold onto the base plate 1, thereby reducing the space occupied by the storage device. That is, when the variable support 31 is supported in the three-dimensional direction, the storage device is three-dimensional. When the three-dimensional support is lost, the storage device changes from three-dimensional to a relatively flat surface and loses the storage space 7.

[0028] like Figure 7As shown, each side support 3 includes a vertical plate 4 and an outer casing 5 covering the vertical plate 4 to ensure that the enclosure 2 can stand upright. The lower edge of the enclosure 2 is connected to the base plate 1. The base plate 1 includes a support plate 11 and an outer casing 5 (i.e., bottom outer casing 12) covering the support plate 11. The outer casing 5 (bottom outer casing 12) of the base plate 1 is connected to the outer casing 5 (side outer casing 51) of the side support 3. All outer casings 5 ​​are connected together to form a whole flexible body 8. The outer casing 5 of the side support 3 is the side outer casing 51, and the support outer casing 5 of the base plate 1 is the bottom outer casing 12. Both are made of fabric and are connected by sewing. The enclosure of the enclosure 2 is achieved through the side outer casing 51, that is, the connection between the side support 3 is through the side outer casing. The connection of the outer casing 51 is achieved. The upright plate 4 is the supplier of three-dimensional support, and the side outer casing 51 is the receiver of three-dimensional support. At the same time, the connection between the side outer casings 51 causes the support bodies 3 on each side to affect each other. Therefore, the side outer casing 51 is also a linkage for state switching. When the side outer casing 51 is supported three-dimensionally, each support body 3 on each side can remain upright. When the side outer casing 51 loses three-dimensional support, neither support body 3 on any side can remain upright (the side outer casing 51 that loses the upright plate 4 becomes soft, collapses and deforms, and the side support body 3 that still has the upright plate 4 loses support and falls down). This realizes the switching between use and folding of the storage device. All outer casings 5 ​​are made of flexible materials, such as flexible cloth, which can maintain the consistency of the appearance of the storage device and facilitate sewing.

[0029] In this embodiment, as Figure 2 , 6 As shown in Figure -8, the base plate 1 is rectangular, specifically a rectangle. The enclosure 2 includes four side supports 3. One set of oppositely arranged side supports 3 are variable supports 31, and the other set of oppositely arranged side supports 3 are closed supports 32. When the upright plate 4 of the variable support 31 leaves the corresponding outer enclosure 5, the two closed supports 32 can fall towards each other and rest against the base plate 1. When the base plate 1 is rectangular, once the two oppositely arranged variable supports 31 lose their three-dimensional support, the closed supports 32 also lose their lateral support and cannot continue to stand upright. They will fall down in an upright posture. No matter what shape the base plate 1 is, the closed supports 32 cannot achieve the folding of the two adjacent side supports 3 in this solution.

[0030] More specifically, the base plate 1 has two long sides and two short sides. The variable support 31 is a side support 3 located on the two long sides, in which the upright plate 4 is a long plate 41. The closed support 32 is a side support 3 located on the two short sides, in which the upright plate 4 is a short plate 42. The length of the long side is greater than or equal to twice the height of the side support 3. When the long plate 41 leaves the outer casing 5, the two closed supports 32 fall down towards each other and each abuts against the base plate 1. In this scheme, the folding scheme is more reasonable. The two closed supports 32 cannot be stacked together, so that the thickness after folding is only the thickness of the base plate 1 and the thickness of a single closed support 32. Even if the pulled-out long plate 41 is added after folding, the overall thickness is still relatively thin.

[0031] In addition, the variable support 31 is a side support 3 located on two short sides, and the closed support 32 is a side support 3 located on two long sides, which can also achieve the function. When the short plate 42 leaves the outer casing 5, the two closed supports 32 fall down towards each other and are stacked on the base plate 1 in sequence. However, in this scheme, although the short plate 42 in the variable support 31 is smaller and easier to disassemble and assemble, the thickness after stacking is larger and not flat enough. Therefore, the first scheme is selected.

[0032] Furthermore, such as Figure 2 , 3 As shown, the opening and closing structure 6 includes an opening 61 and a switch structure 62 disposed at the opening 61. The outer casing 5 is a layered structure with at least two flexible layers 52 and a receiving space 53 for accommodating the upright plate 4 is formed between the different flexible layers 52. The opening 61 is disposed on the outer casing 5 and communicates with the receiving space 53. The switch structure 62 is configured to control the opening 61 to open or close. When the opening 61 is open, the receiving space 53 is open. When the opening 61 is closed, the receiving space 53 is closed. In this embodiment, the opening 61 is disposed on the side of the outer casing 5 of the variable support 31. The outer contour of the outer casing 5 is closed by stitching, and the stitching is broken at the opening 61. The switch structure 62 is a Velcro structure, a snap structure, or a button structure. In this embodiment, a Velcro structure is used, and the switch structure 62 is located on the inner side of the two flexible layers 52. Example

[0033] This embodiment is basically the same as embodiment 1, except that the number and position of the opening and closing structures 6 are different, and the folding method of the storage device is changed. Specifically: like Figure 9-11As shown, a portable mobile storage device includes a flexible body 8, which includes at least four outer casings 5: a bottom outer casing 12 and at least three side outer casings 51 arranged in a ring around the bottom outer casing 12. Each outer casing 5 has a plate 9 inside. The bottom outer casing 12 and at least one side outer casing 51 are provided with an opening and closing structure 6. The opening and closing structure 6 is configured such that when the opening and closing structure 6 is opened, the corresponding outer casing 5 is opened, and the plate 9 can enter or leave the corresponding outer casing 5. When the plate 9 is located inside the outer casing 5, the side outer casing 51 stands upright on the bottom outer casing 12, and a storage space 7 for placing items is formed between the bottom outer casing 12 and the side outer casing 51. The bottom outer casing 12 is located at the bottom to support the items. When the plate 9 leaves the bottom outer casing 12 and the side outer casing 51 with the opening and closing structure 6, the side outer casing 51 without the opening and closing structure 6 can be folded closed. This solution is another way to achieve folding of portable mobile storage devices. It mainly involves removing the plates 9 of the bottom outer casing 12 and the plates 9 of the side outer casing 51, so that the remaining two side outer casings 51 and their plates 9 can move relative to each other. The two side outer casings 51 and their plates 9 can achieve close folding by rotating or moving closer to each other. Even if the plates 9 in multiple side outer casings 51 cannot be removed, they can still be folded after multiple movements.

[0034] In this embodiment, the bottom outer casing 12 is rectangular, so it also has four side supports 3, two opposing variable supports 31 and two opposing closed supports 32. The top edges of the two variable supports 31 are provided with opening and closing structures 6, and the side plates of the bottom outer casing are also provided with opening and closing structures 6. When all openings 61 are open, the two plates 9 of the variable supports 31 are removed from the side outer casing 51 and the plates 9 in the bottom outer casing 12 are taken out. Then the other two opposing closed supports 32 can be brought close to each other to achieve folding.

[0035] If the bottom outer body 12 is triangular, there is only one variable support 31. The plate 9 of the bottom outer body 12 and the plate 9 of this variable support 31 can be pulled out, so that the other two closed supports 32 can be closed by rotation. This scheme is not shown in the figure.
