Description

Technical Field

[0001] This application relates to the technical field of storage cabinets, and particularly to a foldable self-adaptive storage cabinet. Background Art

[0002] Storage cabinets are an indispensable part of modern home environments. With the accelerating urbanization process and the increasingly tight living space, people's requirements for storage cabinets are not only for storage functions, but also for space-saving and flexibility. Although traditional fixed storage cabinets have stable and reliable structures, they are difficult to meet diverse living needs in limited spaces. Especially in small-sized apartments or temporary living places, fixed storage furniture often becomes one of the factors restricting the space utilization efficiency.

[0003] To address the above problems, various design solutions for foldable storage cabinets have emerged in the market. These designs usually achieve spatial changes by changing the connection methods of cabinet components. For example, hinge connections, slide rail fittings, etc. are used to enable the cabinet to be unfolded during use and folded up when not in use, thus greatly reducing the floor area. Common means include but are not limited to: 1) Using rotary joints to connect the side panels to the bottom panel so that they can rotate freely around a certain axis; 2) Setting telescopic rods or cable systems inside the cabinet to facilitate quick adjustment of the height and width of the cabinet; 3) Utilizing elastic elements such as springs to assist the cabinet door or other movable parts to automatically close or open. For example, the patent with publication number CN221083088U discloses a foldable wardrobe.

[0004] However, most existing products fail to fully consider the actual demand changes in different scenarios, resulting in relatively single functionality and being unable to well adapt to diverse storage requirements. Therefore, how to design a new type of foldable storage cabinet that is both simple and practical has become an urgent technical problem to be solved. Summary of the Invention

[0005] To meet the requirements in different scenarios, this application provides a foldable self-adaptive storage cabinet.

[0006] The foldable self-adaptive storage cabinet provided by this application adopts the following technical solutions: A foldable self-adaptive storage cabinet includes a horizontal plate, side panels, connecting frames, and adjusting plates. The side panels are located between the horizontal plate and the connecting frames. The side panels and the horizontal plate are hinged around axis X1, and the side panels and the connecting frames are hinged around axis X2. Axis X1 is parallel to axis X2 and parallel to the horizontal plate. One end of the adjusting plate is slidably connected to the connecting frame in the X direction, and the X direction is parallel to axis X1. When the side plate is perpendicular to the horizontal plate: The other end of the adjusting plate is used for sliding connection with the side plate in the Z direction, and the Z direction is perpendicular to the horizontal plate.

[0007] By adopting the above technical solution, in the unused state, the adjusting plate can be moved to be parallel to the horizontal plate, and then the side plate can be flipped so that the horizontal plate is close to the adjusting plate, reducing the occupied space.

[0008] Usage state 1: Expand until the side plate is perpendicular to the horizontal plate, and the adjusting plate remains parallel to the horizontal plate, that is, the adjusting plate is used as a shelf board, and items can be placed on the adjusting plate.

[0009] Usage state 2: Expand until the side plate is perpendicular to the horizontal plate, one end of the adjusting plate moves in the X direction, and the other end of the adjusting plate moves in the Z direction (vertically), so that the adjusting plate is perpendicular to the horizontal plate, that is, the adjusting plate is used as a back board, and items (such as long coats) can be hung in the storage cabinet.

[0010] Preferably, it further includes a support rod, a magnetic member and a magnetic attraction member. The support rod and the adjusting plate are hinged around an axis L1, and the axis L1 is parallel to the adjusting plate. The magnetic member is connected to the support rod. The magnetic attraction member is connected to the side plate. When the side plate is perpendicular to the horizontal plate and the adjusting plate is parallel to the horizontal plate: The magnetic force between the magnetic attraction member and the magnetic member is used to make the support rod abut against the side plate.

[0011] By adopting the above technical solution, during the process of expanding until the side plate is perpendicular to the horizontal plate, the magnetic force between the magnetic attraction member and the magnetic member makes the support rod automatically lift, so that the support rod automatically provides a support function when the storage cabinet switches to usage state 1.

[0012] At the same time, when the storage cabinet switches to usage state 1, the side plate is usually held to move the storage cabinet, then the support rod is used to prevent the side plate from tipping over, which is beneficial to the safe movement of the storage cabinet.

[0013] Preferably, the axis L1 is perpendicular to the Y direction, the Y direction is perpendicular to the X direction, and the Y direction is parallel to the horizontal plate. The side plate includes an upper plate and a lower plate. The upper plate and the horizontal plate are hinged around an axis X1, the lower plate and the connecting frame are hinged around an axis X2, and the upper plate and the lower plate are hinged around an axis X3, and the axis X3 is parallel to the axis X1. The magnetic member includes an upper magnetic block and a lower magnetic block. Both the upper magnetic block and the lower magnetic block are connected to the support rod. The magnetic attraction member includes an upper magnetic attraction block and a lower magnetic attraction block. The upper magnetic attraction block is connected to the upper plate, and the lower magnetic attraction block is connected to the lower plate. When the lower plate is parallel to the horizontal plate and the adjusting plate is parallel to the horizontal plate: the lower magnetic attraction block and the lower magnetic block attract each other. When the upper plate and / or the lower plate is perpendicular to the horizontal plate and the adjusting plate is parallel to the horizontal plate: the upper magnetic attraction block and the upper magnetic block attract each other, and the lower magnetic attraction block and the lower magnetic block attract each other.

[0014] By adopting the above technical solution, in the unused state, the adjusting plate moves to be parallel to the horizontal plate, and the upper plate and the lower plate both flip towards the space between the horizontal plate and the adjusting plate, and the upper plate and the lower plate do not extend out of the space between the horizontal plate and the adjusting plate, reducing the occupied area.

[0015] And in the unused state, the lower plate and the support rod attract each other by magnetic force, which is beneficial to maintaining the storage state.

[0016] In the case of usage state 1, both between the upper plate and the support rod and between the lower plate and the support rod attract each other by magnetic force, so that the support rod can provide stable support for the side plate.

[0017] Preferably, the upper magnetic attraction block is slidably connected to the upper plate. The lower plate is provided with an embedding groove for the lower end of the upper magnetic attraction block to be embedded. When the side plate is perpendicular to the horizontal plate, the adjusting plate is parallel to the horizontal plate, and the support rod abuts against the side plate: the upper magnetic attraction block is magnetized by the upper magnetic block, the lower magnetic attraction block is magnetized by the lower magnetic block, and the magnetic force between the upper magnetic attraction block and the lower magnetic attraction block causes the upper magnetic attraction block to move upward to disengage from the embedding groove. When the side plate is perpendicular to the horizontal plate, the adjusting plate is parallel to the horizontal plate, and the support rod disengages from the side plate: gravity causes the upper magnetic attraction block to move downward to be embedded in the embedding groove.

[0018] By adopting the above technical solution, when switching from usage state 1 to usage state 2, manually drive the support rod to rotate to disengage from the side plate, and gravity causes the upper magnetic attraction block to move downward to be embedded in the embedding groove to lock the upper plate and the lower plate. Furthermore, during the switching process of the usage state of the storage cabinet, the side plate will not fold; then move the adjusting plate to be used as the back panel to complete the switching to state 2.

[0019] Preferably, it further includes a locking pin. The locking pin is slidably connected to the horizontal plate along the Z direction. The side plate is provided with a locking groove for the lower end of the locking pin to be embedded. The magnetic force between the magnetic part and the locking pin is a repulsive force. When the side plate is perpendicular to the horizontal plate, the adjusting plate is parallel to the horizontal plate, and the support rod abuts against the side plate: the magnetic force between the magnetic part and the locking pin causes the locking pin to move upward to disengage from the locking groove. When the side plate is perpendicular to the horizontal plate, the adjusting plate is parallel to the horizontal plate, and the support rod is separated from the side plate: Gravity causes the locking pin to move downward and embed into the locking groove.

[0020] By adopting the above technical solution, when switching from use state 1 to use state 2, manually drive the support rod to rotate until it separates from the side plate. Gravity causes the locking pin to move downward and embed into the locking groove to lock the side plate and the horizontal plate. Thus, during the switching process of the use state of the storage cabinet, the side plate will not fold; then move the adjusting plate to be used as the back panel to complete the switching to state 2.

[0021] Preferably, an elastic member is further included. The elastic member is connected between the support rod and the adjusting plate, and the elastic member causes the support rod to have a tendency to rotate. Axis L1 is perpendicular to the Y direction, the Y direction is perpendicular to the X direction, and the Y direction is parallel to the horizontal plate.

[0022] By adopting the above technical solution, during the process of unfolding until the side plate is perpendicular to the horizontal plate, the elastic member is used to further ensure that the support rod automatically lifts, so as to automatically provide a support function for the support rod when the storage cabinet switches to use state 1.

[0023] At the same time, when switching from use state 1 to use state 2, after the adjusting plate is moved to be used as the back panel, the support rod automatically unfolds, and the support rod abuts against the horizontal plate, which is beneficial to limit the position of the adjusting plate.

[0024] Preferably, a limiting strip is further included. The limiting strip is connected to the side plate, and the length direction of the limiting strip is parallel to the X direction. When the side plate is perpendicular to the horizontal plate and the adjusting plate is perpendicular to the horizontal plate: between the limiting strip and the horizontal plate is for the support rod to embed.

[0025] By adopting the above technical solution, in use state 2, the support rod embeds between the limiting strip and the horizontal plate to limit the position of the adjusting plate, so that the adjusting plate is stably used as the back panel.

[0026] Preferably, the limiting strip is slidably connected to the side plate, and the magnetic force between the limiting strip and the magnetic member is an attractive force.

[0027] By adopting the above technical solution, in use state 2, the support rod unfolds, and the support bar embeds between the limiting strip and the horizontal plate through the magnetic force.

[0028] Preferably, a locking pin is further included. The locking pin is slidably connected to the horizontal plate along the Z direction. The side plate is provided with a locking groove for the lower end of the locking pin to embed. The locking pin is provided with a slot for the limiting strip to embed.

[0029] By adopting the above technical solution, when in the usage state 2, the support rod is unfolded, and the limiting strip is inserted into the slot to lock the position of the locking pin.

[0030] Preferably, it further includes a reset member. The reset member is connected between the limiting strip and the side plate, and is used to drive the limiting strip to disengage from the support rod.

[0031] By adopting the above technical solution, after manually driving the support rod to disengage from the limiting strip, the reset member automatically drives the limiting strip to reset.

[0032] In summary, the present application includes at least one of the following beneficial technical effects: The adjusting plate can be freely switched between the horizontal and vertical positions, not only used as a shelf, but also capable of hanging long items, improving the functionality and flexibility of the storage cabinet; Through the sliding connection between the adjusting plate and the side plate and the adsorption effect of the magnetic members, the stability and reliability of the adjusting plate in different states are ensured; The synergistic effect among the support rod, the magnetic members and the magnetic attraction members makes the folding and unfolding process of the storage cabinet smoother and more convenient, reducing the operation difficulty of the user and improving the user experience.

The hinge axes at both places are parallel to the X direction.

[0046] When the storage cabinet is not in use, all the side plates 3 are folded towards the inside of the storage cabinet to reduce the space occupied.

[0049] Two cylindrical pins are provided at the end of the adjusting plate 41 along the Y direction. The Y direction is horizontal and the Y direction is perpendicular to the X direction. One cylindrical pin is used to slide and fit into the connecting groove 23; when the side plate 3 is perpendicular to the horizontal plate 12, the other cylindrical pin is used to slide and fit into the side groove 33.

[0051] Usage state 2: When the side plate 3 is unfolded to be perpendicular to the horizontal plate 12, one end of the adjusting plate 41 moves along the X direction and the other end of the adjusting plate 41 moves along the Z direction (vertically), so that the adjusting plate 41 is perpendicular to the horizontal plate 12, that is, the adjusting plate 41 serves as a back plate, and items can be hung in the storage cabinet.

[0052] Refer to Figure 3 , the storage cabinet further includes a support rod 42, a magnetic member 5 and a magnetic attracting member 6.

[0053] One end of the support rod 42 is hinged to the end of the adjusting plate 41 along the Y direction around the axis L1; the axis L1 is parallel to the adjusting plate 41 and L1 is perpendicular to the Y direction.

[0054] The magnetic member 5 is connected to the support rod 42, and the magnetic attracting member 6 is connected to the side plate 3.

[0055] When the side plate 3 is perpendicular to the horizontal plate 12 and the adjusting plate 41 is parallel to the horizontal plate 12: the magnetic force between the magnetic attracting member 6 and the magnetic member 5 is used to make the support rod 42 abut against the side plate 3.

[0056] Specifically: the magnetic member 5 includes an upper magnetic block 51 and a lower magnetic block 52; the magnetic attracting member 6 includes an upper magnetic attracting block 61 and a lower magnetic attracting block 62.

[0057] Both the upper magnetic block 51 and the lower magnetic block 52 are connected to the support rod 42. The upper magnetic attracting block 61 is connected to the upper plate 31, and the lower magnetic attracting block 62 is connected to the lower plate 32.

[0060] When the side plate 3 is perpendicular to the horizontal plate 12, the adjusting plate 41 is parallel to the horizontal plate 12, and the support rod 42 abuts against the side plate 3: the upper magnetic attracting block 61 is magnetized by the upper magnetic block 51, the lower magnetic attracting block 62 is magnetized by the lower magnetic block 52, and the magnetic force between the upper magnetic attracting block 61 and the lower magnetic attracting block 62 makes the upper magnetic attracting block 61 move upward to disengage from the embedding groove 34; When the side plate 3 is perpendicular to the horizontal plate 12 , the adjustment plate 41 is parallel to the horizontal plate 12 , and the support rod 42 is separated from the side plate 3 , gravity causes the upper magnetic block 61 to move downward to be embedded in the embedding groove 34 .

[0061] Reference Figure 4 The storage cabinet also includes an elastic member, a limit strip 7 and a reset member.

[0062] The elastic member is connected between the support rod 42 and the adjustment plate 41, and the elastic member enables the support rod 42 to have a rotation tendency. In one example, the elastic member can be a torsion spring.

[0063] The limiting strip 7 is slidably connected to the upper plate 31, and the sliding direction of the limiting strip 7 is perpendicular to the upper plate 31. The length direction of the limiting strip 7 is parallel to the X direction.

[0067] The reset member is connected between the limit bar 7 and the side plate 3, and is used to drive the extension section 71 to move into the slide groove 35 along the Y direction (the limit bar 7 is separated from the support rod 42).

[0070] When the side plate 3 is perpendicular to the horizontal plate 12, the adjustment plate 41 is parallel to the horizontal plate 12, and the support rod 42 contacts the side plate 3: the magnetic force between the magnetic member 5 and the lock pin 8 causes the lock pin 8 to move upward to disengage from the lock slot 36. When the side plate 3 is perpendicular to the horizontal plate 12, the adjusting plate 41 is parallel to the horizontal plate 12, and the support rod 42 is separated from the side plate 3: Gravity causes the locking pin 8 to move downward and embed into the locking groove 36.
