Description

Technical Field

[0001] This application relates to the field of storage device technology, and more particularly to a storage cabinet. Background Technology

[0002] Lockers, as a basic storage device, are widely used in offices, public places, logistics warehouses, and homes. Traditional lockers typically consist of a frame structure and doors. The frame structure includes side panels and shelves, with the doors rotating and connected to the side panels. The shelves are used to place items, and the side panels are located on the left and right sides of the shelves. Lockers are mainly divided into open lockers and closed lockers. Open lockers are open from front to back and can be used as bookshelves. Closed lockers are closed at the back and open / close at the front via rotating doors, and can be used as wardrobes for storing clothing.

[0003] In related technologies, both open and closed lockers use rigidly connected frame structures. The components are fixedly connected by welding or bolts, making it impossible to switch between the two. They have a single purpose, and the rigid frame structure cannot be folded for storage, takes up a large area, and is inconvenient for transportation and storage. Utility Model Content

[0004] The purpose of this application is to provide a locker that allows the locker to switch freely between a folded state, an open state, and a closed state.

[0005] This application discloses a locker, which includes:

[0006] A side panel assembly, comprising a first side panel and a second side panel, both extending vertically, the first side panel and the second side panel being spaced apart from each other in the left-right direction, the first side panel and the second side panel being able to move closer to each other and further away in the left-right direction, so as to be able to switch between a folded state and an unfolded state, and when the side panel assembly is in the unfolded state, a front-to-back open accommodating space is formed between the first side panel and the second side panel.

[0007] Multiple shelves are arranged vertically between the first side panel and the second side panel. The shelves can switch between a stowed state and a flat state. When the side panel assembly is in the unfolded state, the shelves can be in the flat state and laid flat. When the side panel assembly is in the folded state, the shelves can be in the stowed state.

[0008] A front door panel, which is hinged to the front end of the first side panel, is rotatable about its hinge point and has a first position that closes the front side of the accommodating space and a second position that opens the front side of the accommodating space.

[0009] The rear plate is hinged to the rear end of the second side plate and is rotatable about its hinge point, having a third position that closes the rear side of the accommodating space and a fourth position that opens the rear side of the accommodating space.

[0010] Specifically, when the front door panel is in the first position, the free end of the front door panel can abut against the front end of the second side panel; when the rear panel is in the third position, the free end of the rear panel can abut against the rear end of the first side panel, thus closing the accommodating space front and back; when the front door panel is in the second position, the front door panel can fit against the side of the first side panel facing away from the second side panel; when the rear panel is in the fourth position, the rear panel can fit against the side of the second side panel facing away from the first side panel.

[0011] The above-mentioned technical features have at least the following technical effects:

[0012] In this application, by setting up a side panel assembly, shelves, a rear panel, and a front door panel, the first and second side panels in the side panel assembly are arranged opposite each other to form an accommodating space. The two can move closer or further apart to have an unfolded state and a folded state. The front door panel is hinged to the front end of the first side panel and can rotate around the first side panel to open or close the front side of the accommodating space. The rear panel is hinged to the rear end of the second side panel and can rotate around the second side panel to open or close the rear side of the accommodating space. By setting up rotatable front and rear door panels and making them rotate in opposite directions, the front and rear sides of the accommodating space can be opened or closed, thereby realizing the free switching between the closed and open states of the storage cabinet.

[0013] Meanwhile, the shelves themselves can switch between a folded state and a flat state. When the locker is in the open state, by switching the shelves to the folded state and the side panel assembly from the unfolded state to the folded state, the side panel assembly, shelves, front door panel and back panel can be stacked together along the left and right direction of the locker, thus switching the locker from the open state to the folded state. This realizes the free switching between the folded state, open state and closed state of the locker, improves the use of the locker, and facilitates the transportation and storage of the locker in the folded state.

[0014] In one exemplary embodiment of this disclosure, the first side plate includes a first plate body, a first front longitudinal beam disposed at the front end of the first plate body, and a first rear longitudinal beam disposed at the rear end of the first plate body.

[0015] The second side plate includes a second plate body, a second front longitudinal beam disposed at the front end of the second plate body, and a second rear longitudinal beam disposed at the rear end of the second plate body;

[0016] The left and right ends of the plate abut against the first plate and the second plate, respectively;

[0017] The front door panel is hinged to the first front longitudinal beam. When the front door panel is in the first position, the free end of the front door panel abuts against the second front longitudinal beam. When the front door panel is in the second position, the front door panel is attached to the first panel.

[0018] The rear plate is hinged to the second rear longitudinal beam. When the rear plate is in the third position, the free end of the rear plate abuts against the first rear longitudinal beam. When the rear plate is in the fourth position, the rear plate is attached to the second plate.

[0019] The above-mentioned technical features have at least the following technical effects:

[0020] By setting the first front longitudinal beam and the first rear longitudinal beam, it is easy to connect the first side panel with the shelf and the front door panel. By setting the second front longitudinal beam and the second rear longitudinal beam, it is easy to connect the second side panel with the shelf and the rear panel. The left and right ends of the shelf abut against the first panel and the second panel respectively. Its left end is connected to the first front longitudinal beam and the first rear longitudinal beam respectively, and its right end is connected to the second front longitudinal beam and the second rear longitudinal beam respectively, so that the shelf can remain stable in the flat state.

[0021] In one exemplary embodiment of this disclosure, the first front longitudinal beam is provided with at least two first hinges spaced apart along its length, and one end of the front door panel is connected to the first hinges to be hinged to the first front longitudinal beam via the first hinges.

[0022] The second rear longitudinal beam is provided with at least two second hinges at intervals along its length, and one end of the rear plate is connected to the second hinges so as to be hinged to the second rear longitudinal beam through the second hinges.

[0023] The above-mentioned technical features have at least the following technical effects:

[0024] By incorporating multiple first hinges, the front door panel can rotate more stably around the first front longitudinal beam, resulting in better connectivity. Similarly, by incorporating multiple second hinges, the rear panel can rotate more stably around the second rear longitudinal beam, also resulting in better connectivity.

[0025] In one exemplary embodiment of this disclosure, when the front door panel is in the second position, the free end of the front door panel does not extend beyond the first rear longitudinal beam in the front-rear direction;

[0026] When the rear plate is in the fourth position, the free end of the rear plate does not extend beyond the second front longitudinal beam in the front-rear direction.

[0027] The above-mentioned technical features have at least the following technical effects:

[0028] By ensuring that the free end of the front door panel does not extend beyond the first rear longitudinal beam in the front-back direction, the front door panel will not protrude beyond the first rear longitudinal beam in the rear direction of the storage cabinet. Similarly, by ensuring that the free end of the rear panel does not extend beyond the second front longitudinal beam in the front-back direction, the rear panel will not protrude beyond the second front longitudinal beam in the front direction of the storage cabinet. This makes the storage cabinet more organized and aesthetically pleasing when it is in an open or folded state.

[0029] In one exemplary embodiment of this disclosure, the front door panel includes a plurality of front door sub-panels that are hinged sequentially along its width direction. One end of the front door sub-panel located at the first end is hinged to the first front longitudinal beam. Each front door sub-panel can be rotated sequentially so that all the front door panels are located on the same plane, thereby making the front door panel in an unfolded state. Furthermore, each front door panel can be rotated sequentially so that the front door panels are stacked together, thereby making the front door panel in a folded state.

[0030] The width of the front door panel is less than or equal to the distance between the first front longitudinal beam and the first rear longitudinal beam. When the front door panel is in the unfolded state, the front door panel is connected to the second front longitudinal beam. When the front door panel is in the folded state, the front door panel is attached to the first panel.

[0031] The above-mentioned technical features have at least the following technical effects:

[0032] By setting multiple front door panels, adjacent front door panels are hinged together, allowing the front door panels to switch between an unfolded state and a folded state. When unfolded, they can close the front side of the storage space, while when folded, they can fit against the first side panel to prevent them from extending beyond the first rear longitudinal beam. Ultimately, this makes the storage cabinet more neat and aesthetically pleasing when in an open or folded state.

[0033] In one exemplary embodiment of this disclosure, the rear plate includes a plurality of rear sub-plates that are sequentially hinged along its width direction. One end of the rear sub-plate located at the first end is hinged to the second rear longitudinal beam. Each rear sub-plate can be rotated sequentially so that all the rear sub-plates are located on the same plane, thereby making the rear plate in an unfolded state. Furthermore, each rear sub-plate can be rotated sequentially so that the rear sub-plates are stacked together, thereby making the rear plate in a folded state.

[0034] The width of the rear sub-plate is less than or equal to the distance between the second front longitudinal beam and the second rear longitudinal beam. When the rear plate is in an unfolded state, the rear plate is connected to the first rear longitudinal beam. When the rear plate is in a folded state, the rear plate is attached to the second plate.

[0035] The above-mentioned technical features have at least the following technical effects:

[0036] By setting multiple rear sub-panels, adjacent rear sub-panels are hinged together, allowing the rear panel to switch between an unfolded state and a folded state. When it is unfolded, it can close the rear side of the storage space, while when it is folded, it can fit against the second side panel to prevent it from extending beyond the second front longitudinal beam. Ultimately, this makes the storage cabinet more neat and aesthetically pleasing when it is in an open or folded state.

[0037] In one exemplary embodiment of this disclosure, the shelf includes a first sub-shelf and a second sub-shelf arranged in a left-right direction. The first sub-shelf and the second sub-shelf are hinged at one end. The front and rear sides of the end of the first sub-shelf away from the second sub-shelf are respectively rotatably connected to the first front longitudinal beam and the first rear longitudinal beam. The front and rear sides of the end of the second sub-shelf away from the first sub-shelf are respectively rotatably connected to the second front longitudinal beam and the second rear longitudinal beam, so that the shelf has the flat state and the stowed state. When the shelf is in the flat state, the first sub-shelf and the second sub-shelf are located on the same plane to support items. When the shelf is in the stowed state, the first sub-shelf and the second sub-shelf are close to each other.

[0038] The above-mentioned technical features have at least the following technical effects:

[0039] By making the shelves include a first sub-shelf and a second sub-shelf, with one end of the first sub-shelf and the other end rotatably connected to the side panel assembly, the shelves can switch between a flat state and a folded state, so that the locker can switch from an open state to a folded state, which facilitates the transportation and storage of the locker.

[0040] In one exemplary embodiment of this disclosure, the locker further includes a folding mechanism, which includes a pull rod extending in a vertical direction and a rotating assembly corresponding to each of the shelves. The pull rod is disposed on the rear side of the first sub-shelf and the second sub-shelf and corresponds to the hinge joint of the first sub-shelf and the second sub-shelf.

[0041] The rotating assembly includes a rotating shaft, a first rotating block, and a second rotating block. The first rotating block is fixedly disposed at the rear end of the first sub-layer plate, and the second rotating block is fixedly disposed at the rear end of the second sub-layer plate. The rotating shaft extends in the front-back direction and is fixed to the pull rod. The ends of the first rotating block opposite to the first side plate and the ends of the second rotating block opposite to the second side plate are rotatably connected to the rotating shaft. When the pull rod is pulled upward, it can drive the ends of the first sub-layer plate opposite to the second sub-layer plate and the ends of the second sub-layer plate opposite to the first sub-layer plate to move closer to each other.

[0042] The above-mentioned technical features have at least the following technical effects:

[0043] By setting a folding mechanism, which includes a pull rod and a rotating component for the corresponding shelf, the locker can be switched from an open state to a folded state by pulling the pull rod to bring the first and second side panels together, as well as the first and second sub-shelves together. This simplifies the state switching steps of the locker and makes it easier to operate.

[0044] In one exemplary embodiment of this disclosure, the folding mechanism further includes a sliding block, a first stabilizing rod, and a second stabilizing rod. The sliding block is slidably disposed on the pull rod. One end of the first stabilizing rod is rotatably connected to the sliding block, and the other end is rotatably connected to the rear end of the first rear longitudinal beam and the first sub-layer plate. One end of the second stabilizing rod is rotatably connected to the sliding block, and the other end is rotatably connected to the rear end of the second rear longitudinal beam and the second sub-layer plate. The first sub-layer plate rotatably connected to the first stabilizing rod and the second sub-layer plate rotatably connected to the second stabilizing rod belong to the same layer plate.

[0045] When the side panel assembly is in the deployed state, the first stabilizer bar and the second stabilizer bar are set at acute angles to the tie rod.

[0046] The above-mentioned technical features have at least the following technical effects:

[0047] By setting a first stabilizer bar, a second stabilizer bar, and a sliding block, when the side panel assembly is in the unfolded state, the first and second stabilizer bars and the tie rod are all set at acute angles, so that the line connecting the first stabilizer bar, the second stabilizer bar, and the shelf forms a triangle. The triangular structure is stable, which allows the shelf to be stably laid flat, enabling the shelf to bear a greater load.

[0048] In one exemplary embodiment of this disclosure, the locker further includes a top panel located above all the shelves. One end of the top panel is rotatably connected to the first side panel or the second side panel, and is capable of rotating in a vertical plane perpendicular to the first side panel or the second side panel. When the side panel assembly is in the unfolded state, the free end of the top panel abuts against the second side panel or the first side panel. When the side panel assembly is in the folded state, the top panel is attached to the first side panel or the second side panel.

[0049] The above-mentioned technical features have at least the following technical effects:

[0050] By setting a top plate that can be rotatably connected to the first or second side plate, the top plate can fit against the first or second side plate when the locker is in a folded state, allowing the locker to be folded up as much as possible, reducing its volume and making it easier to transport.

[0051] Beneficial effects:

[0052] In this application, by setting up a side panel assembly, shelves, a rear panel, and a front door panel, the first and second side panels in the side panel assembly are arranged opposite each other to form an accommodating space. The two can move closer or further apart to have an unfolded state and a folded state. The front door panel is hinged to the front end of the first side panel and can rotate around the first side panel to open or close the front side of the accommodating space. The rear panel is hinged to the rear end of the second side panel and can rotate around the second side panel to open or close the rear side of the accommodating space. By setting up rotatable front and rear door panels and making them rotate in opposite directions, the front and rear sides of the accommodating space can be opened or closed, thereby realizing the free switching between the closed and open states of the storage cabinet.

[0053] Meanwhile, the shelves themselves can switch between a folded state and a flat state. When the locker is in the open state, by switching the shelves to the folded state and the side panel assembly from the unfolded state to the folded state, the side panel assembly, shelves, front door panel and back panel can be stacked together along the left and right direction of the locker, thus switching the locker from the open state to the folded state. This realizes the free switching between the folded state, open state and closed state of the locker, improves the use of the locker, and facilitates the transportation and storage of the locker in the folded state.

Detailed Implementation

[0064] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0065] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0066] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0067] The terms “include” and “have”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0068] In related technologies, both open and closed lockers employ rigidly connected frame structures, with components fixedly connected irreversibly via welding or bolts. They cannot be converted between the two, have limited uses, and the rigid frame structure prevents folding for storage, resulting in a large footprint and inconvenience for transportation and storage. To address these technical problems, this application proposes a new type of locker.

[0069] For ease of understanding, the side of the locker facing the user when it is placed on the ground is called the front side, and the side of the locker facing away from the user is called the back side.

[0070] See Figures 1 to 6 A storage cabinet may include a side panel assembly 1. The side panel assembly 1 may include a first side panel 10 and a second side panel 11, both extending vertically to form vertical panels. The first side panel 10 and the second side panel 11 are spaced apart from each other in the left-right direction. The first side panel 10 and the second side panel 11 may have identical structures, differing only in their relative positions. An open-plan accommodating space is formed between the first side panel 10 and the second side panel 11.

[0071] In some embodiments, the locker may further include multiple shelves 2, which are arranged vertically between the first side panel 10 and the second side panel 11. The two ends of the shelf 2 may be connected to the first side panel 10 and the second side panel 11 respectively to support the shelf 2. The shelf 2 is used to place items.

[0072] In some embodiments, the locker may include a front door panel 3. The front door panel 3 is hinged to the front end of the first side panel 10 and is rotatable about its hinge point, having a first position with the accommodating space closed and a second position with the front side of the accommodating space open. The locker may include a rear panel 4. The rear panel 4 is hinged to the rear end of the second side panel 11 and is rotatable about its hinge point, having a third position with the rear side of the accommodating space closed and a fourth position with the accommodating space open.

[0073] By setting a rotatable front door panel 3 and a rear panel 4, and making them rotate in opposite directions, the front and rear sides of the storage space can be opened or closed, thereby switching between the closed and open states of the storage cabinet.

[0074] When the front door panel 3 is in the first position, the free end of the front door panel 3 can abut against the front end of the second side panel 11. When the rear panel 4 is in the third position, the free end of the rear panel 4 can abut against the rear end of the first side panel 10, thereby closing the storage space front and back, and the storage cabinet is in a closed state. When the front door panel 3 is in the second position, the front door panel 3 can fit against the side of the first side panel 10 facing away from the second side panel 11. When the rear panel 4 is in the fourth position, the rear panel 4 can fit against the side of the second side panel 11 facing away from the first side panel 10, thereby opening the storage space front and back, and the storage cabinet is in an open state.

[0075] See Figure 5 and Figure 6In some embodiments, the first side panel 10 and the second side panel 11 can move closer to each other in the left-right direction to switch between a folded state and an unfolded state, and the shelf 2 can switch between a stowed state and a flat state. When the first side panel 10 and the second side panel 11 move further apart, maximizing the distance between them, the side panel assembly 1 is in the unfolded state. At this time, an open storage space is formed between the first side panel 10 and the second side panel 11. By controlling the front door panel 3 and the rear panel 4 to rotate in different directions, the storage cabinet can switch between an open state and a closed state. When the side panel assembly 1 is in the unfolded state, the shelf 2 can be unfolded and flattened to accommodate items.

[0076] When the first side panel 10 and the second side panel 11 approach each other, minimizing the distance between them, the side panel assembly 1 is in a folded state. At this time, the shelf 2 can be stowed, allowing the first side panel 10, shelf 2, and second side panel 11 to retract together in the left-right direction, thus folding the locker and reducing its size for easier transport. It should be noted that when the side panel assembly 1 is folded, the front door panel 3 and the rear panel 4 rotate to the second and fourth positions respectively, fitting against the first side panel 10 and the second side panel 11. In this state, the locker is stacked as close together as possible in the left-right direction, facilitating transport.

[0077] In some embodiments, the first side panel 10 may include a first plate body 100, which is the main structure of the first side panel 10. The first plate body 100 extends vertically to form a flat plate structure. The first side panel 10 may also include a first front longitudinal beam 101 disposed at the front end of the first plate body 100 and a first rear longitudinal beam 102 disposed at the rear end of the first plate body 100. The front and rear ends of the first plate body 100 are sandwiched between the first front longitudinal beam 101 and the first rear longitudinal beam 102. By providing the first front longitudinal beam 101 and the first rear longitudinal beam 102, it is convenient for the first side panel 10 to be connected to the shelf 2 and the front door panel 3.

[0078] In some embodiments, the second side panel 11 may include a second plate body 110, which is the main structure of the second side panel 11. The second plate body 110 extends vertically and forms a flat plate structure. The second side panel 11 may also include a second front longitudinal beam 111 disposed at the front end of the second plate body 110 and a second rear longitudinal beam 112 disposed at the rear end of the second plate body 110. The front and rear ends of the second plate body 110 are sandwiched between the second front longitudinal beam 111 and the second rear longitudinal beam 112. By providing the second front longitudinal beam 111 and the second rear longitudinal beam 112, it is convenient for the second side panel 11 to be connected to the layer 2 and the rear plate 4.

[0079] In some embodiments, the left and right ends of the shelf 2 abut against the first plate 100 and the second plate 110 respectively, the left end of which is connected to the first front longitudinal beam 101 and the first rear longitudinal beam 102 respectively, and the right end of which is connected to the second front longitudinal beam 111 and the second rear longitudinal beam 112 respectively, so that the shelf 2 can be fixed in the flat state.

[0080] In some embodiments, the front door panel 3 is hinged to the first front longitudinal beam 101. When the front door panel 3 is in the first position, the free end of the front door panel 3 abuts against the second front longitudinal beam 111 to close the area between the first and second front longitudinal beams 101, thereby closing the front side of the accommodating space. When the front door panel 3 is in the second position, the front door panel 3 rotates around the first front longitudinal beam 101 and fits against the first panel 100, thereby opening the front side of the accommodating space.

[0081] In some embodiments, the rear plate 4 is hinged to the second rear longitudinal beam 112. When the rear plate 4 is in the third position, the free end of the rear plate 4 abuts against the first rear longitudinal beam 102 to close the area between the second rear longitudinal beam 112 and the first rear longitudinal beam 102, thereby closing the rear side of the accommodating space. When the rear plate 4 is in the fourth position, the rear plate 4 rotates around the second rear longitudinal beam 112 and fits against the second plate 110, thereby opening the rear side of the accommodating space.

[0082] In some embodiments, a first magnetic chuck can be provided on the free ends of both the front door panel 3 and the rear panel 4, while a second magnetic chuck can be provided on both the second front longitudinal beam 111 and the first rear longitudinal beam 102. When the free end of the front door panel 3 abuts against the second front longitudinal beam 111 and the free end of the rear panel 4 abuts against the first rear longitudinal beam 102, the front door panel 3 is magnetically connected to the second front longitudinal beam 111 through the magnetic attraction of the first and second magnetic chucks, and the rear panel 4 is magnetically connected to the first rear longitudinal beam 102 through the magnetic attraction of the first and second magnetic chucks, making it convenient for users to use the locker.

[0083] In some embodiments, the first front longitudinal beam 101 may be provided with at least two first hinges 103 at intervals along its length. One end of the front door panel 3 is connected to the first hinge 103, so as to be hinged to the first front longitudinal beam 101 through the first hinge 103. By providing multiple first hinges 103, the rotation of the front door panel 3 around the first front longitudinal beam 101 can be more stable and the connection can be better. In this embodiment, two first hinges 103 are provided along the length of the first front longitudinal beam 101, respectively near the top and bottom ends of the first front longitudinal beam 101. The first hinges 103 can be hinges.

[0084] In some embodiments, the second rear longitudinal beam 112 may be provided with at least two second hinges 104 at intervals along its length. One end of the rear plate 4 is connected to the second hinge 104 to be hinged to the second rear longitudinal beam 112. By providing multiple second hinges 104, the rear plate 4 can rotate more stably around the second rear longitudinal beam 112, resulting in better connectivity. In this embodiment, two second hinges 104 are provided at intervals along the length of the second rear longitudinal beam 112, respectively near the top and bottom ends of the second rear longitudinal beam 112. The second hinges 104 can be the same as the first hinges 103, both being hinges.

[0085] In some embodiments, to make the locker more neat and aesthetically pleasing when in an open or folded state, when the front door panel 3 is in the second position, the free end of the front door panel 3 does not extend beyond the first rear longitudinal beam 102 in the front-rear direction, so that the front door panel 3 does not protrude from the first rear longitudinal beam 102 in the rearward direction of the locker. When the rear panel 4 is in the fourth position, the free end of the rear panel 4 does not extend beyond the second front longitudinal beam 111 in the front-rear direction, so that the rear panel 4 does not protrude from the second front longitudinal beam 111 in the frontward direction of the locker.

[0086] In some embodiments, the width of the front door panel 3 can be made less than or equal to the width of the first side panel 10, so that the current door panel 3 does not exceed the first rear longitudinal beam 102 when it is in the second position.

[0087] In some embodiments, the width of the rear plate 4 can be made less than or equal to the width of the second side plate 11, so that the rear plate 4 does not exceed the second front longitudinal beam 111 when it is in the fourth position.

[0088] See Figure 3 and Figure 4 In some embodiments, the front door panel 3 may include a plurality of front door sub-panels 30 hinged sequentially along its width. One end of the front door panel 30 at the first end is hinged to the first front longitudinal beam 101. Each front door sub-panel 30 can rotate sequentially to position all front door panels 30 on the same plane, thus placing the front door panel 3 in an unfolded state. Each front door panel 30 can also rotate sequentially to stack together, thus placing the front door panel 3 in a folded state. The width of the front door panel 30 is less than or equal to the distance between the first front longitudinal beam 101 and the first rear longitudinal beam 102. When the front door panel 3 is in the unfolded state, it connects to the second front longitudinal beam 111. When the front door panel 3 is in the folded state, it adheres to the first panel 100, ensuring that the free end of the front door panel 3 does not extend beyond the first rear longitudinal beam 102 in the front-rear direction.

[0089] In some embodiments, two, three, or more front door panels 30 may be provided. In this embodiment, two front door panels 30 are provided, and the width of the front door panel 30 is equal to the distance between the first front longitudinal beam 101 and the first rear longitudinal beam 102. When the front door panel 3 is in the folded state, the two front door panels 30 are stacked together and fit against the first panel 100. At the same time, since the front door panel 3 needs to connect with the second front longitudinal beam 111 to close the front side of the accommodating space when the front door panel 3 is in the unfolded state, the width of the front door panel 3 in the unfolded state is equal to the distance between the first front longitudinal beam 101 and the second front longitudinal beam 111. The distance between the first front longitudinal beam 101 and the second front longitudinal beam 111 is N times the width of the first panel 100, where N depends on the number of front door panels 30. For example, in this embodiment, when there are two front door panels 30, N is 2.

[0090] In some embodiments, adjacent front door panels 30 can be hinged together by connecting hinges.

[0091] In some embodiments, the rear plate 4 may include a plurality of rear sub-plates 40 that are hinged sequentially along its width. One end of the rear sub-plate 40 located at the first end is hinged to the second rear longitudinal beam 112. Each rear sub-plate 40 can be rotated sequentially so that all rear sub-plates 40 are in the same plane, thereby unfolding the rear plate 4. Each rear sub-plate 40 can also be rotated sequentially so that the rear sub-plates 40 are stacked together, thereby folding the rear plate 4. The width of the rear sub-plate 40 is less than or equal to the distance between the second front longitudinal beam 111 and the second rear longitudinal beam 112. When the rear plate 4 is in the unfolded state, the rear plate 4 is connected to the first rear longitudinal beam 102. When the rear plate 4 is in the folded state, the rear plate 4 is attached to the second plate 110, such that the free end of the rear plate 4 does not extend beyond the second front longitudinal beam 111 in the front-rear direction.

[0092] In some embodiments, two, three, or more rear sub-plates 40 may be provided. In this embodiment, two rear sub-plates 40 are provided, and the width of the rear sub-plates 40 is equal to the distance between the second front longitudinal beam 111 and the second rear longitudinal beam 112. When the rear plate 4 is in the folded state, the two rear sub-plates 40 overlap together and fit against the second plate 110. At the same time, since the rear plate 4 needs to connect with the first rear longitudinal beam 102 to close the rear side of the accommodating space when the rear plate 4 is in the unfolded state, the width of the rear plate 4 in the unfolded state can be equal to the distance between the first rear longitudinal beam 102 and the second rear longitudinal beam 112. The distance between the first rear longitudinal beam 102 and the second rear longitudinal beam 112 is M times the width of the second plate 110, where M depends on the number of rear sub-plates 40. For example, in this embodiment, when there are two rear sub-plates 40, M is 2.

[0093] In some embodiments, adjacent rear sub-plates 40 can be hinged together by connecting hinges.

[0094] In some embodiments, the shelf 2 may include a first sub-shelf 20 and a second sub-shelf 21 arranged in a left-right direction. The first sub-shelf 20 and the second sub-shelf 21 are hinged at one end and can rotate about the hinge point. The front and rear sides of the end of the first sub-shelf 20 away from the second sub-shelf 21 are respectively rotatably connected to the first front longitudinal beam 101 and the second front longitudinal beam 111, and the front and rear sides of the end of the second sub-shelf 21 away from the first sub-shelf 20 are respectively rotatably connected to the second front longitudinal beam 111 and the second rear longitudinal beam 112, so that the shelf 2 has the above-mentioned flat state and folded state.

[0095] When shelf 2 is in its flat state, the first sub-shelf 20 and the second sub-shelf 21 are on the same plane, allowing shelf 2 to unfold and flatten to support items. When shelf 2 is in its folded state, the first sub-shelf 20 and the second sub-shelf 21 move closer together, stacking on top of each other in the left-right direction for easy storage. Specifically, external force can be used to bring the first side panel 10 and the second side panel 11 closer together, forcing the first sub-shelf 20 and the second sub-shelf 21 to rotate in opposite directions, thus bringing them closer together and changing shelf 2 from its flat state to its folded state.

[0096] In some embodiments, the first sub-layer plate 20 and the second sub-layer plate 21 have the same structure, and their hinge point is located on the center line of the plate 2 in the left-right direction.

[0097] See Figure 7 and Figure 8 In some embodiments, the locker may also include a folding mechanism 5. By providing the folding mechanism 5, the locker can be switched from an open state to a folded state, reducing the difficulty and burden of operation for the user.

[0098] The folding mechanism 5 may include a pull rod 50 extending in the vertical direction and a rotating component 51 corresponding to each layer plate 2. The pull rod 50 is located on the rear side of the first sub-layer plate 20 and the second sub-layer plate 21 and corresponds to the hinge of the first sub-layer plate 20 and the second sub-layer plate 21, that is, the pull rod 50 is located on the center line of the rear side of the accommodating space.

[0099] The rotating assembly 51 includes a rotating shaft 510, a first rotating block 511, and a second rotating block 512. The first rotating block 511 is fixedly disposed at the rear end of the first sub-layer plate 20, and the second rotating block 512 is fixedly disposed at the rear end of the second sub-layer plate 21. The rotating shaft 510 extends in the front-back direction and is fixed to the pull rod 50. The end of the first rotating block 511 facing away from the first side plate 10 and the end of the second rotating block 512 facing away from the second side plate 11 are both rotatably connected to the rotating shaft. When the pull rod 50 is pulled upward, it can drive the end of the first sub-layer plate 20 facing away from the second sub-layer plate 21 and the end of the second sub-layer plate 21 facing away from the first sub-layer plate 20 to move closer together, so that the first sub-layer plate 20 and the second sub-layer plate 21 gradually move closer together during the upward lifting process, so that the shelf 2 changes from a flat state to a folded state. Since one end of the first sub-layer plate 20 and the second sub-layer plate 21 are rotatably connected to the first side plate 10 and the second side plate 11, when the first sub-layer plate 20 and the second sub-layer plate 21 move closer to each other, they can drive the first side plate 10 and the second side plate 11 to move closer to each other, thereby causing the side plate assembly 1 to switch from the unfolded state to the folded state, and causing the locker to switch from the open state to the folded state.

[0100] In some embodiments, a handle may be provided at the top of the pull rod 50 so that the user can grip and pull the pull rod 50 upward. It should be noted that when it is necessary to switch the locker from a folded state to an open state, simply push the pull rod 50 downward to switch the first sub-shelf 20 and the second sub-shelf 21 from a folded state to a flat state, and drive the first side panel 10 and the second side panel 11 away from each other so that the side panel assembly 1 unfolds.

[0101] In some embodiments, each shelf 2 may be provided with two rotating components 51, one connected to the rear end of the shelf 2 and connected to the tie rod 50, and the other connected to the front end of the shelf 2. The two rotating components 51 are symmetrically arranged about the front and rear of the shelf 2. Both rotating components 51 are used to hinge the first sub-shelf 20 and the second sub-shelf 21. The connection relationship between the rotating component 51 located at the front end of the shelf 2 and the first sub-shelf 20 and the second sub-shelf 21 can be referenced to the connection relationship between the rotating component 51 located at the rear end of the shelf 2 and the first sub-shelf 20 and the second sub-shelf 21. By symmetrically arranging the two rotating components 51, the connection between the first sub-shelf 20 and the second sub-shelf 21 is more stable and the force is more even, enabling the shelf 2 to bear a greater load when it is in a flat state.

[0102] In some embodiments, the folding mechanism 5 may further include a sliding block 52, a first stabilizing rod 53, and a second stabilizing rod 54. The sliding block 52 is slidably disposed on the pull rod 50. One end of the first stabilizing rod 53 is rotatably connected to the sliding block 52, and the other end is rotatably connected to the rear end of the first rear longitudinal beam 102 and the first sub-layer plate 20. One end of the second stabilizing rod 54 is rotatably connected to the sliding block 52, and the other end is rotatably connected to the rear end of the second rear longitudinal beam 112 and the second sub-layer plate 21. The first sub-layer plate 20 rotatably connected to the first stabilizing rod 53 and the second sub-layer plate 21 rotatably connected to the second stabilizing rod 54 belong to the same layer plate 2.

[0103] When the side panel assembly 1 is in the unfolded state, the first stabilizer bar 53 and the second stabilizer bar 54 are all set at acute angles with the tie rod 50, so that the line connecting the first stabilizer bar 53, the second stabilizer bar 54 and the shelf 2 forms a triangle. The triangle structure is stable, which allows the shelf 2 to be stably laid flat, so that the shelf 2 can bear a greater load.

[0104] In some embodiments, the folding mechanism 5 may further include a latch 55, which is fixedly connected to the sliding block 52. The pull rod 50 has a fastening portion 56. When the side panel assembly 1 is in the unfolded state, the latch 55 and the fastening portion 56 lock together, keeping the sliding block 52 and the pull rod 50 relatively fixed. This, in turn, keeps the first stabilizing rod 53 and the second stabilizing rod 54 relatively fixed, thereby improving the stability of the shelf 2 and preventing uncontrolled rotation. When it is necessary to switch the side panel assembly 1 to the folded state, the latch 55 and the fastening portion 56 can be decoupled, allowing the sliding block 52 to slide freely along the pull rod 50. This allows the shelf 2 to change from a flat state to a folded state when the pull rod 50 is pulled up.

[0105] In some embodiments, the locker may further include a top panel 6, which is used to close the top side of the accommodating space, thus sealing the locker. The top panel 6 is located above all the shelves 2, and one end of the top panel 6 is rotatably connected to the first side panel 10 or the second side panel 11, allowing it to rotate in a vertical plane perpendicular to the first side panel 10 or the second side panel 11. When the side panel assembly 1 is in the unfolded state, the free end of the top panel 6 abuts against the second side panel 11 or the first side panel 10 to close the top side of the accommodating space. When the side panel assembly 1 is in the folded state, the top panel 6 is attached to the first side panel 10 or the second side panel 11. When the side panel assembly 1 changes from the unfolded state to the folded state, the top panel 6 can rotate in the direction of being attached to the second side panel 11 or the first side panel 10.

[0106] In some embodiments, by providing a top plate 6 that is rotatably connected to the first side plate 10 or the second side plate 11, the top plate 6 can fit against the first side plate 10 or the second side plate 11 when the locker is in a folded state, so that the locker can be folded up as much as possible, reducing the volume of the locker and making it easier to transport.

[0107] In some embodiments, to facilitate rotation of the top plate 6, when the top plate 6 is rotatably connected to the first side plate 10, the top plate 6 extends between the first front longitudinal beam 101 and the first rear longitudinal beam 102, and is rotatably connected to the first front longitudinal beam 101 and the first rear longitudinal beam 102; or, the top plate 6 extends between the second front longitudinal beam 111 and the second rear longitudinal beam 112, and is rotatably connected to the second front longitudinal beam 111 and the second rear longitudinal beam 112, so that the top plate 6 can rotate relative to the first side plate 10 or the second side plate 11. When the side plate assembly 1 is in a folded state, the top plate 6 can be fitted together with the first plate body 100 or the second plate body 110.
