Description

Technical Field

[0001] This utility model relates to the field of mailbox structures, and more particularly to a foldable mailbox. Background Technology

[0002] A mailbox is a structure placed at the door of a residence or on a street to store newspapers, letters, and packages. However, it should be noted that because mailboxes need to hold items, they often require a relatively large space, resulting in higher space and costs during transportation and storage, which is not conducive to the transport and storage of mailboxes. Utility Model Content

[0003] Therefore, there is a need for a foldable mailbox to solve the problem that the existing mailboxes require a large space, resulting in high space and cost during transportation or storage, which is not conducive to the transportation and storage of mailboxes.

[0004] To achieve the above objectives, this utility model provides a foldable mailbox, including a back panel assembly, a first side panel, a second side panel, a door panel, a top panel, and a bottom panel;

[0005] The back panel assembly includes a back panel, a first upright plate, and a second upright plate. The first upright plate and the second upright plate are located on two opposite sides of the back panel and extend forward from the back panel. The extension length of the second upright plate is greater than the extension length of the first upright plate.

[0006] The first side plate is hinged to the first upright plate, so that the first side plate can be stacked on the back plate or unfolded relative to the back plate, and when the first side plate is stacked on the back plate, there is a space between the two to accommodate the bottom plate.

[0007] The second side plate is hinged to the second upright plate, so that the second side plate can be stacked on the back plate or unfolded relative to the back plate, and when the second side plate is stacked on the back plate, there is a space between them to accommodate the first side plate;

[0008] The door panel is detachably hinged to the first side panel or the second side panel;

[0009] The top plate is detachably connected to at least one of the following structures: the back plate, the first upright plate, the second upright plate, the first side plate, and the second side plate.

[0010] The base plate is hinged to the bottom edge of the back plate or the first side plate, so that the base plate can be stacked on the back plate or unfolded relative to the back plate.

[0011] In a preferred embodiment of this application, the length of the first upright plate extending beyond the back plate is the same as the thickness of the bottom plate. By setting the length of the first upright plate extending beyond the back plate to be the same as the thickness of the bottom plate, it is convenient to form a receiving space for the bottom plate between the first side plate and the back plate, which facilitates the close-fitting folding and assembly of the bottom plate. Furthermore, when the bottom plate and the first side plate are stacked on the back plate, they can both be arranged parallel to the back plate to form a flat stacking structure.

[0012] In a preferred embodiment of this application, the length of the second upright plate extending beyond the back plate is the same as the sum of the thicknesses of the first side plate and the bottom plate. By setting the length of the second upright plate extending beyond the back plate to be the same as the sum of the thicknesses of the first side plate and the bottom plate, it is convenient that when the second side plate is stacked on the back plate, the second side plate, the first side plate, and the bottom plate can all be parallel to the back plate, realizing the ability to sequentially adhere and stack the back plate, the bottom plate, the first side plate, and the second side plate.

[0013] In a preferred embodiment of this application, the back panel is rectangular, and the first and second upright panels are located on the two sides of the back panel corresponding to the long side of the rectangle. By setting the back panel to be rectangular, and the first and second upright panels being located on the two sides of the back panel corresponding to the long side of the rectangle, it is convenient to stack the two first and second side panels corresponding to the long side on the back panel using the arrangement of the first and second upright panels, so that the main structure of the mailbox can be conveniently and quickly stacked or unfolded.

[0014] In a preferred embodiment of this application, the width of the second side panel is smaller than the width of the first side panel. By making the width of the second side panel smaller than the width of the first side panel, it is convenient to keep the sum of the widths of the first upright panel and the first side panel consistent with the sum of the widths of the second upright panel and the second side panel when the first side panel and the second side panel are unfolded relative to the back panel.

[0015] In a preferred embodiment of this application, the first side plate is hinged to the first upright plate via multiple hinges, the second side plate is hinged to the second upright plate via multiple hinges, and the bottom plate is hinged to the back plate or the bottom edge of the first side plate via multiple hinges. By using multiple hinges for hinged connections, rotation of the first side plate, the second side plate, and the bottom plate is facilitated.

[0016] In a preferred embodiment of this application, an electronic lock is provided on the door panel, and a photovoltaic panel is provided on the upper surface of the top panel, with the photovoltaic panel electrically connected to the electronic lock. By providing an electronic lock in conjunction with the photovoltaic panel on the upper surface of the top panel, power is supplied to the electronic lock.

[0017] In a preferred embodiment of this application, the top plate has an internal storage slot that can accommodate a controller electrically connected to the electronic lock. By providing a storage slot inside the top plate, the storage space for items is increased. Furthermore, when the mailbox forms its box structure, it insulates part of the heat from the top, reduces the heat received by the inner space of the mailbox, and blocks the battery storage space of the photovoltaic panel and some of the wiring.

[0018] In a preferred embodiment of this application, the base plate is provided with a reinforcing beam, and the mailbox further includes a mounting column with bolt fixing plates at both ends. One end of the mounting column is detachably connected to the reinforcing beam of the base plate via the bolt fixing plate. By providing a reinforcing beam, the supporting capacity of the base plate is strengthened. Furthermore, the mounting column, connected to the reinforcing beam with bolt fixing plates at one end, and the overall structure elevated via bolt fixing plates at the other end, accommodates different loading and unloading heights and provides waterproofing.

[0019] In a preferred embodiment of this application, a plug is further included. One end of the plug is detachably connected to a bolt fixing plate at the other end of the mounting post, and the other end of the plug has a pointed structure. By providing the plug, it is convenient to fix the object to the ground when the ground is soil, by inserting the pointed end of the plug into the ground.

[0020] Unlike existing technologies, the above technical solution has the following advantages: By setting up a back panel assembly and using first and second uprights with different extension lengths, it is easy to keep the bottom plate, first side plate, and second side plate connected to the back panel assembly for storage. This creates space for the bottom plate and first side plate, optimizing the space occupied by the mailbox in the folded state. It avoids the inconvenience of disassembly and reassembly caused by disassembling and re-stacking all the panels of conventional detachable boxes. It adapts to the thickness of each panel. The bottom plate, first side plate, and second side plate are all connected to the back panel assembly by hinges to achieve unfolding and stacking. This facilitates transportation when folded and unfolding and installation upon arrival at the destination. Therefore, based on the technical solution of this application, space occupation can be reduced, and the space and cost during transportation or storage can be lowered, facilitating the transportation and storage of mailboxes.

[0048] Please refer to the following: Figures 1 to 5 This utility model provides a foldable mailbox, including a back panel assembly 10, a first side panel, a second side panel, a door panel 40, a top panel 50, a bottom panel 60, and a mounting post 70.

[0049] The back panel assembly 10 includes an integrally formed back panel 11, a first upright plate 12, and a second upright plate 13. The first upright plate 12 and the second upright plate 13 are located on two opposite sides of the back panel 11 and extend forward from the back panel 11. The extension length of the second upright plate 13 is greater than the extension length of the first upright plate 12.

[0050] Here, "front" refers to the side of the mailbox facing the user when in use. Based on this orientation, the door panel 40 is located in front of the back panel 11. The back panel assembly 10 can be a single, integral structure, where the back panel 11, the first upright panel 12, and the second upright panel 13 are integrally formed; the different names used here are merely for ease of description. Alternatively, the back panel assembly 10 can be an assembled structure, where the back panel 11, the first upright panel 12, and the second upright panel 13 are formed separately, and then the first upright panel 12 and the second upright panel 13 are respectively connected and fixed to the back panel 11; the specific connection and fixing method is not limited. The first upright panel 12 and the second upright panel 13 are preferably perpendicular to the back panel 11, but depending on the actual design requirements, the first upright panel 12 and the second upright panel 13 can also extend forward at an angle relative to the back panel 11, meaning the angle between the first upright panel 12 and the back panel 11, and the angle between the second upright panel 13 and the back panel 11, can be a predetermined obtuse or acute angle. Overall, the back panel assembly 10 forms a U-shaped cross-section.

[0051] by Figure 4 The view shown is for reference only. The first upright plate 12 and the second upright plate 13 are positioned on the left and right sides of the back plate 11, respectively, with the first upright plate 12 on the left and the second upright plate 13 on the right. It is understood that in other embodiments, the extension length of the first upright plate 12 may be greater than the extension length of the second upright plate 13.

[0052] The first side plate 20 is hinged to the first upright plate 12 of the back plate assembly 10, such that the first side plate 20 is stacked on or unfolded relative to the back plate 11, and when the first side plate 20 is stacked on the back plate 11, there is a space between them to accommodate the bottom plate 60. Preferably, when the first side plate 20 is stacked on the back plate 11, the first side plate 20 and the back plate 11 are placed in a generally parallel or nearly parallel manner, and the first side plate 20 is in a folded state relative to the back plate 11. When the first side plate 20 is unfolded relative to the back plate 11, there is a preset angle between the first side plate 20 and the back plate 11, preferably 90 degrees, that is, the first side plate 20 is perpendicular to the back plate 11. Of course, in some feasible embodiments, based on the actual structural design, the preset angle is not limited to 90 degrees, such as the first side plate 20 and the back plate 11 can form an acute angle or an obtuse angle, and the first side plate 20 is in an unfolded state relative to the back plate 11.

[0053] The second side plate 30 is hinged to the second upright plate 13 of the back plate assembly 10, so that the second side plate 30 can be arranged perpendicular to the back plate 11 or parallel to the back plate 11. When the back plate 11 and the second side plate 30 are arranged parallel, there is a space between the second side plate 30 and the back plate 11 to accommodate the first side plate 20. Preferably, when the second side plate 30 is stacked on the first side plate 20, the second side plate 30 and the back plate 11 are placed in a generally parallel or nearly parallel manner. At this time, the second side plate 30 is in a folded state relative to the back plate 11. When the second side panel 30 is unfolded relative to the back panel 11, there is a preset angle between the second side panel 30 and the back panel 11. Preferably, the preset angle is 90 degrees, that is, the second side panel 30 is perpendicular to the back panel 11. Of course, in some feasible embodiments, based on the actual structural design, the preset angle is not limited to 90 degrees. For example, the second side panel 30 and the back panel 11 can form an acute angle or an obtuse angle. At this time, the state of the second side panel 30 relative to the back panel 11 is the unfolded state.

[0054] The door panel 40 is detachably hinged to the first side panel 20 or the second side panel 30.

[0055] The top plate 50 is detachably connected to at least one of the following structures: the back plate 11, the first upright plate 12, the second upright plate 13, the first side plate 20, and the second side plate 30.

[0056] The base plate 60 is hinged to the bottom edge of the back plate 11 or the first side plate 20, allowing the base plate 60 to be stacked on or unfolded relative to the back plate 11. When the base plate 60 is unfolded relative to the back plate 11, the two form a preset angle, preferably perpendicular. In this embodiment, when the base plate 60 is stacked on the back plate 11, the base plate 60 is hinged to the bottom edge of the back plate 11, and the base plate 60 fits against the back plate 11. In other embodiments, when folded, the base plate 60 may be hinged to the base plate of the first side plate 20, and then stacked on the back plate 11 as the first side plate 20 is folded toward the back plate 11.

[0057] The mounting post 70 is detachably connected to the base plate 60. In some alternative embodiments, the mounting post 70 may be omitted, and the mailbox may be installed by other feasible methods such as hooking.

[0058] According to the above structure, during the use of the foldable mailbox, when the mailbox is in the unfolded state, the first upright plate 12 and the first side plate 20 together form the left wall of the box, and the second upright plate 13 and the second side plate 30 together form the right wall of the box. The door panel 40 is connected to the first side plate 20 or the second side plate 30 by a hinge, so that the door panel 40 can be opened and closed. The top plate 50 is connected to the upper end of the back plate 11, the first upright plate 12, the second upright plate 13, the first side plate 20 and the second side plate 30 of the back plate assembly 10. The bottom plate 60 unfolds at the bottom edge of the back plate 11 and forms a preset angle with the back plate 11, and is connected to the inner space enclosed by the lower part of the first upright plate 12, the second upright plate 13, the first side plate 20 and the second side plate 30. The top plate 50 can be connected to the first upright plate 12, the second upright plate 13, the first side plate 20 and the second side plate 30 by bolts, nails or buckles. The space between the back panel 11, the first upright panel 12, the second upright panel 13, the first side panel 20, the second side panel 30, the top panel 50, and the bottom panel 60 forms a space for accommodating items. The mounting post 70 is connected to the bottom panel 60 and fixed to the area to be secured. In use, materials can be inserted through the pre-drilled slots on the door panel 40, the first side panel 20, the second side panel 30, or the back panel 11, or items can be placed directly by opening the door panel 40. To retrieve items, the preset mechanical or electronic lock 41 on the door panel 40 is unlocked.

[0059] When the collapsible mailbox is in the folded state, the mounting post 70 separates from the base plate 60, and the top plate 50 separates from the back plate 11, the first upright plate 12, the second upright plate 13, the first side plate 20, and the second side plate 30. The door panel 40 separates from either the first side plate 20 or the second side plate 30. The base plate 60 is folded so that it is stacked on the back plate 11. At this time, the base plate 60 will be located in the space reserved between the back plate 11 and the first side plate 20. The space reserved between the back plate 11 and the first side plate 20 is formed by the length of the first upright plate 12 extending from its end face. Then, the first side plate 20 is folded towards the back plate 11 along its hinge with the first upright plate 12 until the first side plate 20 is stacked on the base plate 60 already on the back plate 11. Then, the second side plate 30 is folded along its hinge with the second upright plate 13 so that the second side plate 30 is on the first side plate 20, thus realizing the folding process of the back plate assembly 10. The door panel 40 is placed on the second side panel 30, and the top panel 50 and mounting post 70 can be stacked on top of the door panel 40. The door panel 40, top panel 50, mounting post 70 and insert rod 72 can be further secured by binding them on the outside with ropes or straps.

[0060] By designing the back panel assembly 10 and employing first uprights 12 and second uprights 13 with different extension lengths, the bottom panel 60, first side panel 20, and second side panel 30 are easily connected to the back panel assembly 10 for storage. This creates storage space for the bottom panel 60 and first side panel 20, optimizing the space occupied by the mailbox in the folded state. It avoids the inconvenience of disassembly and reassembly caused by disassembling and re-stacking all panels of conventional detachable boxes. The design accommodates the thickness of each panel. The bottom panel 60, first side panel 20, and second side panel 30 are all connected to the back panel assembly 10 via hinges for unfolding and stacking. This facilitates transportation when folded and easy unfolding and installation upon arrival at the destination. Therefore, it reduces space occupation, lowers space and storage costs during transportation and storage, and facilitates the transportation and storage of mailboxes.

[0061] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the length of the first upright plate 12 extending beyond the back plate 11 is the same as the thickness of the bottom plate 60. By setting the length of the first upright plate 12 extending beyond the back plate 11 to be the same as the thickness of the bottom plate 60, it is convenient to form a receiving space for the bottom plate 60 between the first side plate 20 and the back plate 11, which facilitates the close-fitting folding and assembly of the bottom plate 60. Furthermore, when the bottom plate 60 and the first side plate 20 are stacked on the back plate 11, they can both be arranged parallel to the back plate 11 to form a flat stacking structure.

[0062] Please refer to the following: Figures 1 to 5In a preferred embodiment of this application, the length of the second upright plate 13 extending beyond the back plate 11 is the same as the sum of the thicknesses of the first side plate 20 and the bottom plate 60. In this embodiment, since the length of the first upright plate 12 extending beyond the back plate 1 is the same as the thickness of the bottom plate 60, correspondingly, the length of the second upright plate 13 extending beyond the first upright plate 12 is the same as the thickness of the first side plate 20. By setting the length of the second upright plate 13 extending beyond the back plate 11 to be the same as the sum of the thicknesses of the first side plate 20 and the bottom plate 60, it is convenient that when the second side plate 30 is stacked on the back plate 11, the second side plate 30, the first side plate 20, and the bottom plate 60 can all be parallel to the back plate, realizing the ability to sequentially adhere and stack the back plate 11, the bottom plate 60, the first side plate 20, and the second side plate 30. It should be noted that "same" here allows for a certain difference within the error range, that is, if the corresponding values ​​are different, but the difference is within the allowable error range of actual manufacturing, they can be considered the same.

[0063] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the back panel 11 is rectangular, and the first upright panel 12 and the second upright panel 13 are located on the two sides of the back panel 11 corresponding to the long side of the rectangle. By setting the back panel 11 to be rectangular, and the first upright panel 12 and the second upright panel 13 to be located on the two sides of the back panel 11 corresponding to the long side of the rectangle, when the back panel 11 has a rectangular structure, it is convenient to stack the two first side panels 20 and the second side panels 30 on the back panel 11 using the arrangement of the first upright panel 12 and the second upright panel 13. As the main structure of the mailbox, it can be conveniently and quickly stacked or unfolded.

[0064] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the width of the second side plate 30 is smaller than the width of the first side plate 20. By making the width of the second side plate 30 smaller than the width of the first side plate 20, it is convenient to keep the sum of the widths of the first upright plate 12 and the first side plate 20 consistent with the sum of the widths of the second upright plate 13 and the second side plate 30 when the first side plate 20 and the second side plate 30 are unfolded relative to the back plate 11.

[0065] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the first side plate is hinged to the first upright plate 12 via multiple hinges, the second side plate is hinged to the second upright plate 13 via multiple hinges, and the bottom plate 60 is hinged to the bottom edge of the back plate 11 or the first side plate 20 via multiple hinges. By using multiple hinges for hinged connections, rotation of the first side plate 20, the second side plate 30, and the bottom plate 60 is facilitated.

[0066] Please refer to the following: Figures 1 to 5In a preferred embodiment of this application, the door panel 40 is provided with an electronic lock 41, and the upper surface of the top plate 50 is provided with a photovoltaic panel 51, which is electrically connected to the electronic lock 41.

[0067] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the top plate 50 is provided with a storage slot 52 inside, which can accommodate a controller electrically connected to the electronic lock 41. By providing a storage slot 52 inside the top plate 50, the storage space for items is increased, and when the mailbox forms a box structure, it insulates part of the heat at the top, reduces the heat received by part of the inner space of the mailbox, and blocks the battery storage space of the photovoltaic panel 51 and some of the wiring.

[0068] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the base plate 60 is provided with a reinforcing beam 61, and the mailbox further includes a mounting column 70. The mounting column 70 has bolt fixing plates 71 at both ends, and one end of the mounting column 70 is detachably connected to the reinforcing beam 61 of the base plate 60 via the bolt fixing plates 71. By providing the reinforcing beam 61, the supporting capacity of the base plate 60 is strengthened. Furthermore, the mounting column 70, connected to the reinforcing beam 61 by the bolt fixing plates 71 at one end, and the overall structure elevated via the bolt fixing plates 71 at the other end, accommodates different loading and unloading heights and provides waterproofing.

[0069] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, a plug rod 72 is also included. One end of the plug rod 72 is detachably connected to the bolt fixing plate 71 at the other end of the mounting post 70, and the other end of the plug rod 72 has a pointed structure. By providing the plug rod 72, it is convenient to fix the ground when the ground is soil, by inserting the pointed end of the plug rod 72 into the ground.

[0070] In the above embodiments, to ensure the assembly and connection strength of the top plate 50 and the bottom plate 60, when the mailbox is unfolded and in use, the top plate 50 can be connected to all structures of the back plate 11, the first upright plate 12, the second upright plate 13, the first side plate 20, and the second side plate 30, and the bottom plate 60 can be connected to all structures of the first upright plate 12, the second upright plate 13, the first side plate 20, and the second side plate 30.
