Description

Technical Field

[0001] This invention relates to the field of furniture technology, and in particular to a detachable modular upholstered bed frame and bed. Background Technology

[0002] Currently, upholstered bed frames are widely popular among consumers due to their aesthetic appeal, comfortable feel, and ability to effectively prevent collisions. However, existing upholstered bed frames generally suffer from the following technical pain points: (1) Difficult transportation and handling; traditional upholstered bed frames are mostly integral structures or only partially disassembled, making them bulky and heavy. This makes them extremely inconvenient to pass through residential corridors, elevators, or entrance doors, resulting in high transportation costs and limiting online sales. (2) Non-removable or complex internal structure; many upholstered beds use glued or complex mortise and tenon structures for their internal wooden frames, making it difficult to disassemble them without damage after assembly, which is not conducive to moving or storage. For the few beds that use metal frames, the connection method is often not optimized for quick disassembly and assembly, and the assembly tools are complex and the steps are cumbersome. (3) Difficult cleaning and maintenance; the outer fabric and internal filling sponge of most upholstered beds are sewn or glued to the bed frame and cannot be disassembled. After long-term use, the fabric is prone to absorbing dust, breeding mites, or getting stained. Therefore, users can only wipe the surface and cannot clean it thoroughly, which affects the hygiene of the bedroom environment and the health of the user. (4) High personalization and maintenance costs; when the upholstery is partially damaged or the user wants to change the style, the entire bed frame often needs to be replaced or complex professional repairs are required, resulting in high costs.

[0003] Therefore, there is a current need to develop a bed frame that can balance stable load-bearing capacity, convenient disassembly and transportation, and allow for complete removal and washing of the external upholstery, so that it has significant market value and application prospects.

[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] In the description of this invention, it should be understood that the use of terms such as "first" and "second" may explicitly or implicitly include one or more of those features. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] The following is for reference. Figures 1 to 12 A detachable modular upholstered bed frame and bed are described according to embodiments of the present invention.

[0024] like Figures 1 to 12As shown, the detachable modular upholstered bed frame according to the first aspect of the present invention can be applied to bed products. This embodiment combines a structurally stable and detachable metal load-bearing frame 100 with independent and washable upholstered components to achieve convenient disassembly and assembly, efficient transportation, and thorough cleaning and maintenance of the detachable modular upholstered bed frame throughout the entire process.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the detachable modular upholstered bed frame includes a load-bearing frame 100 and upholstered components.

[0026] The load-bearing frame 100 is a detachable metal structure, which can be made of high-strength metal profiles such as stainless steel, offering the advantage of strong load-bearing capacity. The detachable nature of the load-bearing frame 100 facilitates packaging, transportation, and handling after disassembly. The load-bearing frame 100 has a headboard, a footboard, and two side panels, with the headboard and footboard facing each other front-to-back, and the two side panels facing each other left-to-right.

[0027] The soft-pack assembly includes an outer cover and a sponge core, with the sponge core detachably located inside the outer cover. Specifically, the outer cover has a hollow internal structure, meaning it has a storage cavity with an opening allowing the sponge core to enter and be contained within it. The opening of the storage cavity is equipped with a storage zipper, a long zipper sewn onto the outer cover, which can be opened and closed. By opening the storage zipper, the sponge core can be easily placed into or removed from the outer cover's storage cavity. After the sponge core is placed inside the storage cavity, the zipper can be closed. The storage zipper can be located on the lower surface of the outer cover.

[0028] Understandably, the upholstered component consists of an independent, high-density, compressible sponge core and a removable, washable cover. The sponge core serves as the filling material of the upholstered component, and is encased in a cover with a storage zipper. The zipper's closure protects the sponge core. Users can easily open the zipper to remove the sponge core or remove the entire cover for washing, solving the hygiene problem of traditional upholstered bed frames being difficult to clean. Furthermore, when the modular upholstered bed frame is in its unassembled state, the upholstered component can be compressed to less than 30% of its original volume, significantly saving packaging space. Of course, in other embodiments, snaps or Velcro may be used instead of storage zippers at the opening of the storage cavity.

[0029] There are four upholstered components, each with an independent design. The four upholstered components are headboard upholstery 210, footboard upholstery 220, and two sideboard upholstery 230.

[0030] like Figure 6As shown, for the headboard upholstery 210, the bottom surface of the cover has a first storage zipper 211. The first storage zipper 211 extends in the left and right direction. By opening the first storage zipper 211, the sponge core can be removed, making it convenient to replace the cover or the sponge core, and also convenient to wash the cover; as shown Figure 5 As shown, for the bedside upholstery 230, the bottom surface of the cover has a second storage zipper 231. The second storage zipper 231 extends in the front-to-back direction, and its length is less than the length of the cover. By opening the second storage zipper 231, the foam core can be removed, allowing for washing and replacement of the cover or the foam core. Similarly, for the bed foot upholstery 220, the storage zipper is also located on the bottom surface of the cover.

[0031] The headboard upholstery 210 is correspondingly positioned to the headboard, and the headboard upholstery 210 and headboard are detachably connected, allowing the headboard upholstery 210 to be attached and detached from the headboard. Specifically, the back of the headboard upholstery 210 has a receiving cavity with an opening that faces vertically downwards. The headboard is configured to extend into the receiving cavity so that the headboard upholstery 210 can be fitted onto the headboard. It can be understood that by sewing a cloth bag 212 onto the back of the headboard upholstery 210, the headboard upholstery 210 can be secured by simply slipping the cloth bag 212 over the headboard during installation, thus completely concealing the headboard and achieving a neat appearance.

[0032] A footboard upholstery 220 is correspondingly positioned at the foot of the bed, and two sideboard upholstery 230s are correspondingly positioned at the two sides of the bed. The footboard upholstery 220 and the two sideboard upholstery 230s each have a first strap 310 on their outer cover. The first straps 310 are sewn onto the outer cover and are configured to form a first binding hole, the axis of which is perpendicular to the vertical direction. Specifically, the two ends of the first straps 310 are detachably connected via first Velcro. For both the footboard upholstery 220 and the sideboard upholstery 230, there is at least one first strap 310, and at least one first strap 310 is detachably connected to the load-bearing frame 100.

[0033] It is understood that the specific number of the first straps 310 on the cover can be selected according to actual design requirements and is not limited here. The first straps 310 can be made of nylon material. For the footboard upholstery 220, the axis of the first binding hole formed by the first straps 310 extends in the left-right direction, and for the sideboard upholstery 230, the axis of the first binding hole formed by the first straps 310 extends in the front-back direction, thus ensuring that the footboard upholstery 220 and the sideboard upholstery 230 are in a stable height position. Of course, it is not excluded that in other embodiments, the first straps 310 are towels, and the two ends of the first straps 310 are connected by snaps or zipper assemblies.

[0034] The first strap 310 is located on the surface of the outer cover facing the load-bearing frame 100. Multiple straps 310 are provided and spaced apart along the extension direction of the outer cover. One end of the first strap 310 has a first hook-and-loop fastener male, and the other end has a first hook-and-loop fastener female. When installing the footboard upholstery 220 and the sideboard upholstery 230, simply tighten the first strap 310 and adhesively connect the opposite ends of the first strap 310 using the first hook-and-loop fastener male and female, so that the first strap 310 forms a first binding hole and is firmly bound to the load-bearing frame 100. This ensures that the footboard upholstery 220 and the sideboard upholstery 230 can be stably attached to the outside of the load-bearing frame 100. When removing the footboard upholstery 220 and the sideboard upholstery 230, simply pull to release the adhesive of the first hook-and-loop fastener. The footboard upholstery 220 and the sideboard upholstery 230 are fixed to the load-bearing frame 100 by the first strap 310 with the first Velcro, and the headboard upholstery 210 is fixed to the load-bearing frame 100 by the way of the cloth bag 212. By using these non-destructive and reversible methods for installation and fixation, the quick installation and removal of each upholstery component can be achieved.

[0035] Each side panel upholstery 230 and the foot panel upholstery 220 are detachably connected by a zipper 400, so that the foot panel upholstery 220 and the two side panel upholstery 230 together form a U-shaped structure. Specifically, each side panel upholstery 230 and the foot panel upholstery 220 adopts a cuboid structural design. Each side panel upholstery 230 and the foot panel upholstery 220 are arranged perpendicularly. In this embodiment, one end of each side panel upholstery 230 is attached to the surface of the foot panel upholstery 220 near the load-bearing frame 100. The zipper 400 includes a first toothed chain strap 410 and a second toothed chain strap 420, which are engaged with each other. The first toothed chain strap 410 is located at the end of the bed side upholstery 230 near the end upholstery 220. The first toothed chain strap 410 extends horizontally outward from the inner side of the upper surface of the bed side upholstery 230 and vertically downward, forming an L-shape. Correspondingly, the end upholstery 220 has a second toothed chain strap 420 near the surface of the bed side upholstery 230, which is also L-shaped. Both the first toothed chain strap 410 and the second toothed chain strap 420 are sewn onto their respective outer covers.

[0036] Understandably, the side upholstery 230 and the footboard upholstery 220 are connected at adjacent vertical corners via a first toothed chain strap 410 and a second toothed chain strap 420, ensuring a smooth and aesthetically pleasing seam between them. This connection also ensures that the upper surfaces of the side upholstery 230 and the footboard upholstery 220 are flush, preventing sagging due to gravity. Furthermore, either the footboard upholstery 220 or the side upholstery 230 can be disassembled individually, allowing for modular and personalized assembly. The footboard upholstery 220 and the two side upholstery 230 are joined by a zipper 400 to form a continuous U-shaped structure, while also allowing for easy separation by opening the zipper 400. In addition, the bottom surfaces of the left and right ends of the headboard upholstery 210 may be provided with notches so that the headboard upholstery 210 can be respectively attached to the two side upholstery 230s.

[0037] In the detachable modular upholstered bed frame provided in the first aspect embodiment of the present invention, the load-bearing frame 100 adopts a detachable metal structure, which can provide strong load-bearing capacity, ensure the stability and reliability of the bed frame structure, and facilitate transportation and handling through detachable operation; the four upholstered components correspond to the headboard, footboard and two sideboards of the load-bearing frame 100 respectively, wherein the headboard upholstery 210 is detachably connected to the headboard, the footboard upholstery 220 and the two sideboard upholstery 230 are detachably connected to the load-bearing frame 100 through the first strap 310, and each sideboard upholstery 230 is detachably connected to the footboard upholstery 220 through the zipper 400. Therefore, the upholstered components can be quickly disassembled and assembled according to the actual situation, which is convenient for packaging, transportation and maintenance. Different upholstered components can be replaced according to user preferences. Moreover, in each upholstered component, the sponge core can be removed from the inside of the outer cover, which is convenient for cleaning the upholstered component. At the same time, the upholstered components can be greatly compressed to achieve extreme flat packaging and reduce transportation and storage costs.

[0038] In one embodiment of the present invention, such as Figures 1 to 4 As shown, the load-bearing frame 100 has multiple bed legs, which can be arranged in an array. The bed legs can contact the ground to effectively support the load-bearing frame 100. The cover of the footboard upholstery 220 is provided with a second strap 320, and the covers of the two sideboard upholstery 230s are also provided with second straps 320. The second straps 320 can be fixed to the cover using a sewing process. The second straps 320 are configured to form a second binding hole, the axis of which extends vertically. Specifically, the two ends of the second straps 320 are detachably connected by second Velcro. For the footboard upholstery 220 and the sideboard upholstery 230, there is at least one second strap 320, and at least one second strap 320 is detachably connected to the corresponding bed leg.

[0039] Understandably, the specific number of the second straps 320 on the cover can be selected according to actual design requirements and is not limited here. The second straps 320 can be made of nylon material. The second straps 320 are located on the surface of the cover facing the load-bearing frame 100. One end of the second strap 320 is provided with a second hook-and-loop fastener male, and the other end is provided with a second hook-and-loop fastener female. When installing the footboard upholstery 220 and the sideboard upholstery 230, simply tighten the second straps 320 and let the opposite ends of the second straps 320 be glued together through the second hook-and-loop fastener male and female, so that the second straps 320 form a second binding hole and are firmly bound to the bed legs. When removing the footboard upholstery 220 and the sideboard upholstery 230, simply pull to release the second hook-and-loop fastener. For the side upholstery 230, the second Velcro fastener prevents it from shifting in the front-to-back direction. For the footboard upholstery 220, the second Velcro fastener prevents it from shifting in the left-to-right direction, thus ensuring that the side upholstery 230 and footboard upholstery 220 remain stable on the horizontal plane. Of course, in other embodiments, the second strap 320 may be a towel, with both ends connected by snaps or zippers.

[0040] In one embodiment of the present invention, such as Figures 1 to 4 As shown, the load-bearing frame 100 includes a headboard support 110, bed leg rods 120, a crossbeam assembly 130, a longitudinal beam assembly 140, a middle beam assembly 150, and a support rod 160.

[0041] The headboard support 110 has an inverted U-shaped structure, and at least one headboard support 110 is provided. Furthermore, at least one headboard support 110 is detachably connected to the headboard upholstery 210. In this embodiment, two headboard supports 110 are provided, spaced apart along the left-right direction. All the headboard supports 110 together form the headboard, and the headboard upholstery 210 can be fitted onto all the headboard supports 110. The headboard support 110 is made of a hollow circular steel tube.

[0042] The bed leg rods 120 extend vertically, and four bed leg rods 120 are provided, each corresponding to one of the four corners of the load-bearing frame 100. The bottom of each bed leg rod 120 is equipped with a removable anti-slip pad. In this embodiment, the bed leg rods 120 are rectangular hollow tubes made of high-quality cold-rolled steel. The bed leg rods 120 are the bed legs of the load-bearing frame 100.

[0043] The crossbeam assembly 130 has a T-shaped structure, and there are two crossbeam assemblies 130 arranged in a front-to-back configuration. One crossbeam assembly 130 is located on the headboard side of the load-bearing frame 100, and the other crossbeam assembly 130 is located on the footboard side of the load-bearing frame 100.

The headboard upholstery 210 is fitted onto the headboard support 110. It is understood that the threaded fasteners can be screws, or a combination of bolts and nuts.

[0045] The longitudinal beam assembly 140 has a T-shaped structure, and there are two longitudinal beam assemblies 140, which are arranged facing each other from left to right. One longitudinal beam assembly 140 is located on the left side of the load-bearing frame 100, and the other longitudinal beam assembly 140 is located on the right side of the load-bearing frame 100. In this embodiment, the upper part of the longitudinal beam assembly 140 extends in the front-to-back direction, and the lower part of the longitudinal beam assembly 140 extends in the vertical direction. The lower part of the longitudinal beam assembly 140 can abut against the ground to provide a certain degree of support. Each longitudinal beam assembly 140 is perpendicular to one end of each of the two transverse beam assemblies 130 at its opposite ends. Moreover, each longitudinal beam assembly 140 is detachably connected to the corresponding transverse beam assembly 130 via a corresponding bed leg rod 120. That is, one end of the longitudinal beam assembly 140 is detachably connected to the bed leg rod 120, and one end of the transverse beam assembly 130 is detachably connected to the same bed leg rod 120, so that the two longitudinal beam assemblies 140, the two transverse beam assemblies 130, and the four bed leg rods 120 are assembled together to form a rectangular bed frame.

[0046] The intermediate beam assembly 150 has a T-shaped structure and is located between the two longitudinal beam assemblies 140 and the two transverse beam assemblies 130. In this embodiment, the upper part of the intermediate beam assembly 150 extends in the front-to-back direction, and the lower part extends in the vertical direction. The lower part of the intermediate beam assembly 150 can abut against the ground to provide a certain degree of support. The intermediate beam assembly 150 is arranged parallel to the longitudinal beam assemblies 140, and the opposite ends of the intermediate beam assembly 150 are respectively perpendicular to the middle positions of the two transverse beam assemblies 130. Moreover, the ends of the intermediate beam assembly 150 are detachably connected to the middle positions of the corresponding transverse beam assemblies 130, and the detachable connection can be made by bolt connection or screw connection.

[0047] In this embodiment, as Figure 3 , Figure 7 and Figure 9 As shown, the longitudinal beam assembly 140 includes a first support rod 141, a second support rod 142, and a connecting seat 143. The length of the first support rod 141 extends in the vertical direction. There are two second support rods 142, which are symmetrically arranged about the first support rod 141 in the front-back direction. The upper end of the first support rod 141 is provided with a connecting seat 143, which is fixed to the first support rod 141. The connecting seat 143 is provided with a mounting groove 144, which penetrates the upper surface, two opposite sides, and part of the bottom surface at the front and rear ends of the connecting seat 143, so that the two second support rods 142 can be placed in the mounting groove 144 and the second support rods 142 can be folded. The ends of the two second support rods 142 are located in the mounting groove 144, and the ends of the two second support rods 142 are riveted to the connecting seat 143 by rivets in the vertical direction of the axis, so that the second support rods 142 can rotate upward or downward relative to the connecting seat 143. The second support rods 142 are configured to be able to rotate downward at least 90° to fold, and to rotate upward to abut against the bottom surface of the mounting groove 144.

[0048] When the second support rod 142 is rotated upwards to a horizontal position, it presses against the bottom surface of the mounting groove 144 for support, reducing the pressure on the rivets and preventing them from bending, deforming, or even breaking. This allows the first support rod 141, the connecting seat 143, and the two second support rods 142 to form a T-shaped longitudinal beam assembly 140 in its unfolded state. When the second support rod 142 is rotated downwards to a vertical position, it becomes parallel to the first support rod 141, allowing the longitudinal beam assembly 140 to be folded and reducing its space requirements for easier packaging and transportation. Of course, the rotation angle of the second support rod 142 can be greater than 90°, allowing it to be close to the lower end of the first support rod 141.

[0049] Understandably, the two second support rods 142 are connected to the connecting seat 143 on the first support rod 141 by riveting, realizing a movable connection between the second support rods 142 and the connecting seat 143. This allows the first support rod 141, the connecting seat 143, and the two second support rods 142 to form a foldable structure with the first support rod 141 as the supporting pivot. The first support rod 141 can serve as the bed leg of the load-bearing frame 100. Of course, as... Figure 10 As shown, the crossbeam assembly 130 is structurally identical to the longitudinal beam assembly 140, meaning both include a first support rod 141, a second support rod 142, and a connecting seat 143 with a mounting groove 144, which will not be described in detail here. Like the longitudinal beam assembly 140, the crossbeam assembly 130 can be unfolded or folded. For both the crossbeam assembly 130 and the longitudinal beam assembly 140, the specific dimensions of their first support rod 141, second support rod 142, and connecting seat 143 can be arbitrarily set according to actual needs, and are not limited here. For example, the length of the first support rod 141 in the crossbeam assembly 130 may be the same as or different from that in the longitudinal beam assembly 140. For the bed side upholstery 230 and the bed foot upholstery 220, the first strap 310 on the outer cover is detachably connected to the corresponding second support rod 142. Both the first support rod 141 and the second support rod 142 are made of hollow rectangular steel tubing.

[0050] In this embodiment, each crossbeam assembly 130 has a first limiting groove at its middle position. The end of the intermediate beam assembly 150 extends into the first limiting groove, and the end of the intermediate beam assembly 150 is connected to the crossbeam assembly 130 by a threaded fastener. Specifically, for the crossbeam assembly 130, the connecting seat 143 has a first limiting groove at its middle position. The first limiting groove communicates with the mounting groove 144. The first limiting groove and the first support rod 141 are arranged vertically opposite each other. The first limiting groove penetrates the upper surface of the connecting seat 143 and the surface near the intermediate beam assembly 150, so that the end of the intermediate beam assembly 150 can be placed in the first limiting groove from top to bottom. The end of the intermediate beam assembly 150 fits against the two side walls of the first limiting groove. The surface of the connecting seat 143 away from the intermediate beam assembly 150 has a mounting hole 146 for bolts to pass through the mounting hole 146 and connect to the end of the intermediate beam assembly 150, thereby realizing a detachable connection between the intermediate beam assembly 150 and the crossbeam assembly 130.

[0051] Support rods 160 extend in the left-right direction. Multiple support rods 160 are provided between each longitudinal beam assembly 140 and the intermediate beam assembly 150. The multiple support rods 160 are arranged at intervals in the front-back direction. The opposite ends of the support rods 160 are detachably connected to the longitudinal beam assembly 140 and the intermediate beam assembly 150. In this embodiment, the support rods 160 are hollow rectangular steel tubes.

[0052] like Figure 3 and Figure 7As shown, each longitudinal beam assembly 140 is provided with multiple support seats 180 arranged at intervals along the front-to-back direction. The intermediate beam assembly 150 is also provided with multiple support seats 180 arranged along the front-to-back direction. Each support seat 180 has a support groove 181, the opening of which is vertically upward and can extend through the left and right sides of the support seat 180. Specifically, the support seat 180 has a U-shaped structure. A guide part can be provided at the opening of the support groove 181 to allow the end of the support rod 160 to be smoothly inserted. The support seat 180 is fixedly installed by welding. The opposite ends of the support rod 160 can be respectively inserted into the corresponding support groove 181 and abut against the bottom surface of the groove 181, so that the support rod 160 can receive the support provided by the support seat 180.

[0053] Understandably, multiple support rods 160 are installed in parallel between each longitudinal beam assembly 140 and the intermediate beam assembly 150, so that the two crossbeam assemblies 130, the two longitudinal beam assemblies 140, the intermediate beam assembly 150, and the multiple support rods 160 together form the support plane of the bed board or mattress. Furthermore, the second support rod 142 on the longitudinal beam assembly 140 and the intermediate beam assembly 150 are each provided with multiple support seats 180, allowing the two ends of the support rod 160 to be detachably engaged with the corresponding support seats 180 of the longitudinal beam assembly 140 and the intermediate beam assembly 150, respectively. The installation of the support rod 160 can be easily completed without any tools, thus forming a sturdy and flat support plane. The two ends of the intermediate beam assembly 150 are respectively engaged into the first limiting grooves of the two crossbeam assemblies 130 and fixed with bolts, which enhances the torsional strength of the load-bearing frame 100. In this embodiment, the load-bearing frame 100 uses a hybrid connection method combining rivet pre-fixation and bolt quick-installation to ensure its structural stability while enabling rapid assembly and disassembly.

[0054] In one embodiment of the present invention, the load-bearing frame 100 further includes a supporting crossbeam 170. A supporting crossbeam 170 is provided between each longitudinal beam assembly 140 and the intermediate beam assembly 150. The supporting crossbeam 170 extends in a left-right direction. One end of the supporting crossbeam 170 is connected to the middle position of the longitudinal beam assembly 140 via a threaded fastener, and the opposite end of the supporting crossbeam 170 is connected to the middle position of the intermediate beam assembly 150. In this embodiment, the supporting crossbeam 170 is a hollow rectangular steel tube. A second limiting groove 145 is provided at the middle position of the longitudinal beam assembly 140. The end of the supporting crossbeam 170 extends into the second limiting groove 145, and the end of the supporting crossbeam 170 is connected to the longitudinal beam assembly 140 via a threaded fastener.

[0055] Specifically, for the longitudinal beam assembly 140, a second limiting groove 145 is provided at the middle position of the connecting seat 143. The second limiting groove 145 is connected to the mounting groove 144. The second limiting groove 145 is arranged vertically opposite to the first support rod 141. The second limiting groove 145 penetrates the upper surface of the connecting seat 143 and the surface near the intermediate beam assembly 150, so that the end of the supporting crossbeam 170 can be placed in the second limiting groove 145 from top to bottom. The end of the supporting crossbeam 170 fits against the two side walls of the second limiting groove 145. The surface of the connecting seat 143 away from the intermediate beam assembly 150 is also provided with mounting holes 146, so that bolts can pass through the mounting holes 146 and connect with the end of the supporting crossbeam 170, thereby realizing the detachable connection between the supporting crossbeam 170 and the longitudinal beam assembly 140. The two supporting crossbeams 170 and the intermediate beam assembly 150 together form a reinforced support assembly.

[0056] In this embodiment, as Figure 3 , Figure 11 and Figure 12 As shown, the intermediate beam assembly 150 includes a third support rod 151, a fourth support rod 152, and a hinge seat 153. The length of the third support rod 151 extends in the vertical direction. There are two fourth support rods 152, which are symmetrically arranged about the third support rod 151 in the front-back direction. The upper end of the third support rod 151 is provided with a hinge seat 153, which is fixed to the third support rod 151. The hinge seat 153 is cross-shaped when viewed in the vertical direction. The hinge seat 153 is provided with a first hinge groove 154 and two second hinge grooves 155. The first hinge groove 154 penetrates the upper surface, two opposite sides, and part of the bottom surface at the front and rear ends of the hinge seat 153, so that the two fourth support rods 152 can be placed in the first hinge groove 154 and realize the folding function of the fourth support rods 152. The ends of the two fourth support rods 152 are located in the first hinge groove 154, and the ends of the two fourth support rods 152 are riveted to the hinge seat 153 by rivets extending in the left and right directions along the axis, so that the fourth support rods 152 can swing upward or downward relative to the hinge seat 153. The fourth support rods 152 are configured to be able to rotate downward at least 90° to fold, and to rotate upward to abut against the bottom surface of the first hinge groove 154.

[0057] Both the third support rod 151 and the fourth support rod 152 are made of hollow rectangular steel tubes. Multiple support seats 180 are provided on the left and right sides of the fourth support rod 152.

[0058] Two supporting crossbeams 170 are arranged in a one-to-one correspondence with two second hinge slots 155. The two second hinge slots 155 are located on the left and right sides of the first hinge slot 154, respectively. The second hinge slots 155 penetrate the upper surface of the hinge seat 153, the side away from the first hinge slot 154, and part of the bottom surface, so that the supporting crossbeams 170 can be placed in the second hinge slots 155 and realize the folding function of the supporting crossbeams 170. The ends of the supporting crossbeams 170 are located in the corresponding second hinge slots 155, and the ends of the supporting crossbeams 170 are riveted to the hinge seat 153 by rivets extending in the front-back direction along the axis, so that the supporting crossbeams 170 can swing upward or downward relative to the hinge seat 153. The supporting crossbeams 170 are configured to be able to rotate downward at least 90° to fold, and to rotate upward to abut against the bottom surface of the second hinge slot 155.

[0059] After the two fourth support rods 152 and the two support beams 170 have all swung upwards to a horizontal position, as follows: Figure 11 As shown, the fourth support rod 152 presses against the bottom surface of the first hinge groove 154, and the support beam 170 presses against the bottom surface of the second hinge groove 155 to provide some support, reducing the pressure of the fourth support rod 152 and the support beam 170 on the rivet, and preventing the rivet from easily bending, deforming, or even breaking. This allows the two fourth support rods 152 and the two support beams 170 to together form a cross-shaped reinforced support structure in the unfolded state. When both the two fourth support rods 152 and the two support beams 170 swing downwards to a vertical position, as... Figure 12 As shown, the fourth support rod 152 and the support beam 170 are both parallel to the third support rod 151. This allows the reinforcing support assembly to be in a folded state and reduces the space occupied by the reinforcing support assembly, facilitating packaging and transportation. Of course, the rotation angle of the fourth support rod 152 and the rotation angle of the support beam 170 can be greater than 90°, so that the fourth support rod 152 and the support beam 170 can be close to the lower end of the third support rod 151.

[0060] Understandably, the two supporting beams 170 and the two fourth support rods 152 are all connected to the hinge seats 153 on the third support rod 151 by riveting. This allows the fourth support rods 152 and the supporting beams 170 to be movably connected to the hinge seats 153, so that the two supporting beams 170, the two fourth support rods 152, and the hinge seats 153 form a foldable structure with the third support rod 151 as the support pivot. The third support rod 151 can serve as the legs of the load-bearing frame 100. The supporting beams 170 are fixedly installed on the longitudinal beam assembly 140 by snap-fit ​​and bolt connection, and fixedly installed on the intermediate beam assembly 150 by riveting. This simplifies the installation steps of the supporting beams 170, improves installation efficiency, and further enhances the torsional strength and overall rigidity of the load-bearing frame 100. The load-bearing frame 100 in this embodiment is designed to be fully modular, allowing it to be disassembled into standardized components, which facilitates packaging and transportation and reduces transportation and storage costs.

[0061] In this embodiment, each longitudinal beam assembly 140 has six support seats 180 on each of the two second support rods 142. Correspondingly, the two fourth support rods 152 in the intermediate beam assembly 150 have six support seats 180 on their left and right sides respectively. Moreover, the six support seats 180 on the front side and the six support seats 180 on the rear side are symmetrically arranged about the supporting crossbeam 170.

[0062] In one embodiment of the present invention, such as Figure 3 and Figure 8 As shown, each bed leg 120 has a first slot 121 and a second slot 122 at its upper end. The opening direction of the first slot 121 and the opening direction of the second slot 122 are perpendicular to each other and both are open in the horizontal direction. One end of the crossbeam assembly 130 extends into the first slot 121 in the left-right direction, and the other end of the crossbeam assembly 130 is connected to the bed leg 120 by a threaded fastener. One end of the longitudinal beam assembly 140 extends into the second slot 122 in the front-back direction, and the other end of the longitudinal beam assembly 140 is connected to the bed leg 120 by a threaded fastener.

[0063] Specifically, the bed leg rod 120 also includes two connecting plates 123 and a support plate 124, which are fixedly connected to the bed leg rod 120. The support plate 124 is located below the two connecting plates 123 and is connected to the two connecting plates 123, providing support for the connecting plates 123. The two connecting plates 123 are vertically arranged, corresponding to the first slot 121 and the second slot 122, respectively. One connecting plate 123 is located on the side of the opening of the first slot 121 near the longitudinal beam assembly 140, and the other connecting plate 123 is located on the side of the opening of the second slot 122 near the crossbeam assembly 130. The two connecting plates 123 are respectively arranged correspondingly to the crossbeam assembly 130 and the longitudinal beam assembly 140. Each connecting plate 123 has at least one connecting hole 125, the axis of which is perpendicular to the vertical direction. One end of each crossbeam assembly 130 abuts against the bottom surface of the corresponding first slot 121 and is detachably connected to the corresponding connecting hole 125 via threaded fasteners. One end of the longitudinal beam assembly 140 abuts against the bottom surface of the corresponding second slot 122 and is detachably connected to the corresponding connecting hole 125 via threaded fasteners.

[0064] Understandably, the second support rod 142 in the crossbeam assembly 130 is inserted into the corresponding first slot 121 and fits against the inner wall of the first slot 121. It is then detachably connected to the corresponding connecting plate 123 via threaded fasteners. Similarly, the second support rod 142 in the longitudinal beam assembly 140 is inserted into the corresponding second slot 122 and fits against the inner wall of the second slot 122. It is then detachably connected to the corresponding connecting plate 123 via threaded fasteners. This allows the pressure on the second support rod 142 to be distributed across the bed leg rod 120, the connecting plate 123, and the support plate 124, resulting in a stronger load-bearing capacity, greater torsional strength, and a more stable structure for the load-bearing frame 100.

[0065] During factory production, the crossbeam assembly 130, longitudinal beam assembly 140, intermediate beam assembly 150, and bed leg rod 120 are prefabricated. Specifically, for the crossbeam assembly 130 and longitudinal beam assembly 140, two second support rods 142 are riveted to the connecting seats 143 on the first support rod 141, and the ends of the second support rods 142 are provided with screw holes. For the longitudinal beam assembly 140, six support seats 180 with support grooves 181 are welded to each of the two second support rods 142. For the intermediate beam assembly 150, two fourth support rods 152 and two support rods 120 are prefabricated. The crossbeam 170 is hinged to the hinge seat 153 on the third support rod 151 by rivets. The end of the fourth support rod 152 away from the third support rod 151 and the end of the crossbeam 170 away from the third support rod 151 are provided with screw holes. Moreover, six support seats 180 with support grooves 181 are welded to the left and right sides of the two fourth support rods 152. The support rod 160 is supported by the support seats 180. Each bed leg rod 120 is provided with a first slot 121, a second slot 122, a support plate 124 and two connecting plates 123. The connecting plate 123 has two pre-made connecting holes 125.

[0066] After delivery to the user, the user assembles the modular upholstered bed frame according to the installation instructions. During assembly, the second support rods 142 of the two crossbeam assemblies 130 and the two longitudinal beam assemblies 140 are inserted into the first slots 121 and 122 on the corresponding bed leg rods 120, and then tightened with bolts to quickly assemble the rectangular bed frame. Next, the reinforcing support components are installed. Specifically, the fourth support rod 152 of the intermediate beam assembly 150 is fixedly connected to the connecting seats 143 in the two crossbeam assemblies 130, and the two supporting crossbeams 170 are fixedly connected to the connecting seats 143 in the longitudinal beam assembly 140. Then, multiple support rods 160 are inserted into the support grooves 181 of the corresponding support seats 180, thus completing the assembly of the metal load-bearing frame 100. Next, the headboard upholstery 210 is fitted onto the headboard of the load-bearing frame 100. The two side upholsteries 230 and the footboard upholstery 220 are then joined together using zippers 400 to form a U-shaped upholstery structure. This upholstery structure is then fitted over the load-bearing frame 100, corresponding to the footboard and the two side panels, and secured to the load-bearing frame 100 using the first strap 310 and the second strap 320. Finally, the mattress is placed on the load-bearing frame 100, completing the bed assembly. Disassembly and cleaning can be performed in reverse.

[0067] It is understood that the load-bearing frame 100 in this embodiment adopts the design concept of "prefabricated components + quick connection". The main load-bearing beams (such as the crossbeam assembly 130, longitudinal beam assembly 140 and reinforcing support assembly) are pre-connected in the factory by riveting the first support rod 141, the second support rod 142 and the connecting seat 143, and the supporting crossbeam 170, the third support rod 151, the fourth support rod 152 and the hinge seat 153 are pre-connected by riveting to form stable sub-modules. The longitudinal beam assembly 140 and the intermediate beam assembly 150 are equipped with multiple support seats 180 by welding. During on-site assembly, the various sub-modules are connected by bolts or quickly connected to specially designed bed leg rods 120 to form a stable rectangular bed frame. Both ends of the support rod 160 are engaged with the support seats 180 pre-fixed to the longitudinal beam assembly 140 and the intermediate beam assembly 150, thereby enabling the crossbeam assembly 130, longitudinal beam assembly 140, intermediate beam assembly 150, support rod 160, and support crossbeam 170 to form a complete support plane. This hybrid connection method of "pre-fixing key components with rivets and completing the main body connection with bolts" ensures the overall rigidity of the load-bearing frame 100 and the strength of permanent connection points, while enabling users to quickly assemble and disassemble the load-bearing frame 100 without tools or with only simple tools.

[0068] The detachable modular upholstered bed frame provided in the first aspect embodiment of the present invention has the following advantages: (1) Extremely convenient transportation and handling: The metal load-bearing frame 100 can be completely disassembled into simple components such as pipes, and the soft packaging components can be highly compressed. The overall packaging volume can be reduced by more than 60% compared with traditional finished beds, which greatly reduces logistics costs and handling difficulties, and is perfectly adapted to modern e-commerce sales and urban living environments.

[0069] (2) Sturdy and reliable structure and quick assembly / disassembly: The internal main structure is a metal load-bearing frame 100 with strong load-bearing capacity. Moreover, the innovative hybrid connection design (such as a hybrid method of rivets + bolts + snap-fit) enables the load-bearing frame 100 to have both the stability of permanent connection and user-friendly disassembly / assembly. The snap-fit ​​connection between the support rod 160 and the support base 180 makes the installation of the support plane of the load-bearing frame 100 intuitive and simple.

[0070] (3) A complete cleaning and hygiene revolution: All upholstered components can be completely removed independently. The outer cover can be machine washed or hand washed directly, and the sponge core can also be ventilated and dried. This fundamentally solves the century-old problem of upholstered furniture being difficult to clean, greatly improving the user experience and health protection.

[0071] (4) High degree of modularity and personalization: It allows users to change the fabric color or material of any soft-pack component according to their different preferences, so as to achieve flexible changes in home style. Any damaged part (metal component of the load-bearing frame or soft-pack component) can be replaced individually, with low maintenance cost and long product life cycle.

[0072] (5) User-friendly assembly experience: The clear modular design makes the assembly process like "assembling large building blocks". The steps are clear and ordinary users can easily complete the assembly in a short time by referring to the installation instructions, without the need for professional skills or complicated tools.

[0073] like Figures 1 to 12 As shown, the bed according to a second aspect embodiment of the present invention includes a detachable modular upholstered bed frame as in the first aspect embodiment. Additionally, the bed includes a bed board or mattress, wherein the bed board or mattress can be placed on the load-bearing frame 100.

[0074] This embodiment adopts a detachable modular upholstered bed frame with the above-described structure, which makes the bed structurally stable and reliable, quick to assemble and disassemble, easy to package and transport, and convenient to maintain and clean. This helps to improve the handling convenience, maintenance convenience, and user experience of the bed product.
