DETAILED DESCRIPTION

[0057] The following will clearly and completely describe the technical solutions of the present disclosure in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present disclosure, not all of them. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0058] In the description of this disclosure, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" and the like indicate positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate the description of this disclosure and simplify the description, and are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0059] In the description of this disclosure, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on the specific circumstances.

[0060] Definition of orientation in this embodiment: see Figure 1 and Figure 10 As shown, the arrow direction X represents the length direction of the bed box and the length direction of the side panels mounted on the bed box, the arrow direction Y represents the width direction of the bed box and the width direction of the side panels mounted on the bed box, and the arrow direction Z represents the height direction of the bed box and the height direction of the side panels.

[0061] See also Figures 1 to 24 As shown, this embodiment provides a cover body 1, which includes a side portion 11, which is used to wrap around the outer periphery of the bed box 2, and at least part of the side portion 11 can be bent inward to reduce the circumference of the side portion 11.

[0062] The cover body 1 provided in this embodiment can be used on bed boxes of different sizes (for example, large-sized bed boxes and small-sized bed boxes). When in use, the cover body 1 is placed on the large-sized bed box, and the side parts 11 can be wrapped around the outer periphery of the bed box; when the cover body 1 is placed on the small-sized bed box, at least part of the side parts 11 are bent inward so that the circumference of the side parts 11 is reduced to adapt to the circumference of the small-sized bed box, thereby fittingly wrapping around the outer periphery of the small-sized bed box.

[0063] The cover body 1 is made of a flexible material, such as cloth, to ensure that after the cover body 1 is placed on the bed box 2 , the side surrounding parts 11 can be wrapped around the outer periphery of the bed box 2 .

[0064] It should be understood that bed boxes of different sizes refer to bed boxes with different circumferences, which can be different widths, different lengths, or different widths and lengths. A large-sized bed box has a first circumference, and a small-sized bed box has a second circumference, with the first circumference being greater than the second circumference. Normally, when the cover 1 is placed on a large-sized bed box, at least a portion of the side portions 11 need not be bent, thereby achieving the effect of wrapping the side portions 11 around the outer periphery of the bed box. When the cover 1 is placed on a small-sized bed box, at least a portion of the side portions 11 are bent inward, reducing the circumference of the side portions 11 to accommodate the circumference of the small-sized bed box, thereby wrapping around the outer periphery of the small-sized bed box.

[0065] In one embodiment, the side surrounding portion 11 is a flexible annular structure. Figure 1 As shown, the height of the flexible annular structure in the arrow direction Z is greater than the thickness of the bed box, and at least a portion of the annular edge of the flexible annular structure is provided with a tightening member so that the outer peripheral side of the bed box 2 can be wrapped in the flexible annular structure.

[0066] It should be understood that the flexible annular structure in this embodiment refers to a circumferentially enclosed space within the side panel 11, rather than a flexible belt. Before the cover is positioned over the bed box 2, the contour of this enclosed space is not fixed. After the cover is positioned over the bed box 2, the contour of this enclosed space conforms to the contour of the outer periphery of the bed box 2.

[0067] Exemplarily, the flexible annular structure has a first annular edge 111 and a second annular edge 112. When the side surrounding portion 11 is wrapped around the outer peripheral side of the bed box 2, the first annular edge 111 is located above the upper surface of the bed box 2, and the second annular edge 112 is located below the lower surface of the bed box 2. The first annular edge 111 and the second annular edge 112 are both provided with tightening parts (not shown in the figure) to wrap the upper and lower edges of the bed box 2 in the side surrounding portion 11 to prevent the side surrounding portion 11 from slipping off the bed box 2.

[0068] Exemplarily, the tightening member may be an elastic band or a drawstring.

[0069] In one embodiment, see Figure 3 As shown, in order to prevent the side parts 11 from sliding off the bed box 2, the cover body 1 also includes a top cover 12, which is connected to the side parts 11 and is provided with an opening 120, which corresponds to the bendable part of the side parts 11.

[0070] In this embodiment, the top cover portion 12 is connected to the first annular edge 111 of the side surrounding portion 11 . In this case, the tightening member may be provided only on the second annular edge 112 .

[0071] By providing the opening 120 on the top cover 12, a space for escape can be reserved, and when the side parts 11 are bent inward, they will not fold onto the top cover 12, thereby not affecting the flatness of the top cover and ensuring a beautiful appearance. At the same time, the opening 120 facilitates the bending operation.

[0072] The material of the top cover 12 can also be a flexible material. Optionally, the material of the top cover is the same as that of the side surrounding parts 11; in other embodiments, the material of the top cover is different from that of the side surrounding parts 11, specifically, the material of the top cover is non-woven fabric, and the material of the side surrounding parts 11 is jacquard fabric.

[0073] For example, the top cover portion 12 may be sewn onto the side surrounding portion 11 .

[0074] In one embodiment, see Figure 3 As shown, the top cover portion 12 includes a first top cover portion 121 and a second top cover portion 122, and the first top cover portion 121 and the second top cover portion 122 are spaced apart along the width direction of the side surrounding portion 11. The space between the first top cover portion 121 and the second top cover portion 122 forms an opening 120 so that the portion of the side surrounding portion 11 corresponding to the width of the bed box 2 can be bent inward.

[0075] Exemplarily, the first top cover portion 121 is rectangular in shape and has a first long side and a second long side that are opposite to each other, as well as a first short side and a second short side that are opposite to each other, wherein the first long side and the second long side are parallel to the arrow direction X, and the first short side and the second short side are parallel to the arrow direction Y. The first long side, the first short side, and the second short side are all connected to the first annular edge 111 of the side surrounding portion 11; the second top cover portion 122 has a third long side and a fourth long side that are opposite to each other, as well as a third short side and a fourth short side that are opposite to each other, the third long side, the third short side, and the fourth short side are all connected to the first annular edge 111 of the side surrounding portion 11, the second long side and the fourth long side are substantially parallel to each other, and the space between the second long side and the fourth long side forms an opening 120.

[0076] When the side surrounding portion 11 needs to be bent inward to reduce the width, the portion of the side surrounding portion 11 corresponding to the opening 120 may be bent.

[0077] In one embodiment, see Figure 4 and Figure 5 As shown, the cover body 1 further includes a shielding portion 13 , which is connected to the second long side of the first top cover portion 121 . The shielding portion 13 is detachably connected to the second top cover portion 122 to cover the opening 120 .

[0078] For example, the shielding portion 13 is integrally formed with the first top cover portion 121. The shielding portion 13 can be tilted relative to the side surrounding portion 11. When the shielding portion 13 is tilted, the opening 120 is exposed, facilitating inward bending of the side portions. When the shielding portion 13 is lowered, it can be detachably connected to the second top cover portion 122, thereby covering the opening 120 and ensuring an aesthetically pleasing and consistent appearance.

[0079] In one embodiment, a connecting portion 131 is provided on the lower surface of the shielding portion 13 , and a connecting mating portion 1221 is provided on the upper surface of the second top cover portion 122 . The connecting mating portion 1221 cooperates with the connecting portion 131 to connect the shielding portion 13 to the second top cover portion 122 .

[0080] Exemplarily, the connecting portion 131 and the connecting fitting portion 1221 may be Velcro, snap fasteners, or magnetic components that attract each other.

[0081] The connecting portion 131 and the shielding portion 13 may be connected together by sewing or bonding, and the connecting fitting portion 1221 and the second top cover portion 122 may be connected together by sewing or bonding.

[0082] See also Figure 6 and Figure 7 As shown, after the portion of the side surrounding portion 11 corresponding to the opening 120 is bent inward, the shielding portion 13 can cover the second top cover portion 122 .

[0083] In one embodiment, the inner surface of the side surrounding portion 11 is provided with a fixing piece, and the fixing piece is used to maintain the tightened state of the side surrounding portion 11 so that the side surrounding portion 11 is wrapped around the outer periphery of the bed box 2 .

[0084] Specifically, after the side surrounding parts 11 are bent inward, they need to be fixed by fixing parts to ensure that the side surrounding parts 11 are in a tightened state so as to better wrap around the outer periphery of the smaller-sized bed box 2.

[0085] In a possible design, the fixing member includes a strap, which is used to be connected to the bed box 2 to pull the portion of the side panel 11 that extends beyond the bed box 2 toward the inside of the bed box 2 .

[0086] For example, see Figure 8 As shown, the strip is annular, that is, the strip can be an annular strip 113, and the annular strip 113 can be mounted on the set position of the bed box 2. For example, the bed box 2 is provided with a protrusion at the set position, and the protrusion can be a butterfly nut. The annular strip 113 can be mounted on the butterfly nut to pull the part of the side panel 11 that extends beyond the bed box 2 toward the inside of the bed box 2.

[0087] The number of the annular strip 113 can be one or more. Figure 8 As shown, two groups of annular strips are symmetrically provided on the inner surface of the side surrounding portion 11 , each group includes two annular strips 113 , and the two annular strips 113 are spaced apart along the height of the side surrounding portion 11 .

[0088] In other embodiments, each group includes four annular strips 113, wherein two annular strips 113 are arranged on the side surrounding portion 11 near the first annular edge 111, and the other two annular strips 113 are arranged on the side surrounding portion 11 near the second annular edge 112. Figure 21A 、 Figure 21B and Figure 21C As shown, the annular strip 113 can also be a drawstring arranged around the side part 11. By pulling the drawstring, the side part 11 can be tightened to wrap the outer side of the bed box 2, and then the free end of the drawstring is put on the butterfly nut.

[0089] It should be noted that a group of annular strips may also be provided on the inner surface of the side surrounding portion 11 .

[0090] Of course, the strip may also include two straps, which are tied to the support rods of the bed box 2 to achieve the purpose of pulling the portion of the side panel 11 that extends beyond the bed box 2 toward the inside of the bed box 2 .

[0091] In another possible design, see Figure 2 As shown, the fixing member may also include a first adhesive member 114a and a second adhesive member 114b, the first adhesive member 114a is connected to the portion of the side surrounding portion 11 that can be bent inward, and the second adhesive member 114b is connected to other portions of the side surrounding portion 11, and the first adhesive member 114a can be bonded to or separated from the second adhesive member 114b.

[0092] This method can achieve the fixation of the side panel 11 itself without the need for a bed box.

[0093] For example, the first adhesive member 114a and the second adhesive member 114b may be Velcro.

[0094] See also Figure 9 As shown, this embodiment also provides a bed box assembly, including a bed box 2 and a cover body 1 provided in this embodiment. The circumference of the bed box 2 is adjustable, and the side parts 11 are wrapped around the outer periphery of the bed box 2. At least part of the side parts 11 can be bent inward to reduce the circumference of the side parts 11 to match the circumference of the bed box 2.

[0095] The bed box assembly provided in this embodiment utilizes the cover 1 provided in this embodiment. Therefore, regardless of the circumference of the bed box 2, the side panels 11 can wrap around the outer periphery of the bed box 2. Specifically, the cover 1 can be directly placed over a large bed box 2. When the cover 1 is placed over a small bed box 2, at least a portion of the side panels 11 is bent inward, reducing the circumference of the side panels 11 to accommodate the circumference of the smaller bed box 2, thereby wrapping around the smaller bed box 2.

[0096] In this embodiment, the circumference of the bed box 2 is adjustable, which can be achieved by adjusting the width of the bed box 2 or by adjusting the length of the bed box 2. Of course, it can also be achieved by adjusting both the width and length of the bed box 2.

[0097] In one embodiment, see Figure 10 As shown, the bed box 2 includes a first box frame 21, a second box frame 22 and a widened portion. The widened portion is detachably connected between the first box frame 21 and the second box frame 22 to make the width of the bed box 2 adjustable.

[0098] See also Figure 10As shown, when the first box frame 21 and the second box frame 22 are connected together through the widened portion, the bed box 2 has a larger width; see Figure 16 As shown, after the widened portion is separated from the first and second box frames 21, 22, the first and second box frames 21, 22 are placed side by side to form a smaller bed box 2. When the bed box is smaller in width, the first and second box frames 21, 22 are placed side by side with a slight gap between them. When at least a portion of the side frame 11 is bent inward, the bent portion can be positioned between the gaps.

[0099] It should be noted that the structures of the first box frame 21 and the second box frame 22 are existing technologies.

[0100] In one embodiment, in order to enhance the stability of the bed box 2 , the first box frame 21 can be connected to the second box frame 22 via a fastener 23 when the widened portion is separated from the first box frame 21 and the second box frame 22 .

[0101] In addition, by providing the fasteners 23 , it is also convenient to connect the strips on the side surrounding portion 11 with the fasteners 23 .

[0102] In one embodiment, see Figures 16 to 19 As shown, the fastener 23 includes a bolt 231 and a nut 232 . The first box frame 21 and the second box frame 22 are both provided with a through hole 2111 . The bolt 231 passes through the through hole 2111 and is threadedly connected to the nut 232 .

[0103] For example, see Figure 19 and Figure 20 As shown, the bolt 231 is a butterfly bolt and the nut 232 is a butterfly nut, so that the annular strip 113 can be mounted on the heads of the butterfly bolt and the butterfly nut to pull the part of the side panel 11 that exceeds the circumference of the bed box 2 toward the inside of the bed box 2. At the same time, it can effectively prevent the annular strip 113 from falling off.

[0104] See also Figure 21A 、 Figure 21B and Figure 21C As shown, when the annular strip 113 is a drawstring arranged around the side portion 11, the side portion 11 can be tightened by pulling the drawstring to wrap the outer peripheral side of the bed box 2, and then the free end of the drawstring is placed on the head of the butterfly bolt and the butterfly nut.

[0105] For example, taking the first box frame 21 as an example, see Figure 11As shown, the first box frame 21 includes a rectangular parallelepiped frame structure assembled from multiple rods. The first box frame 21 has two opposing long sides, each of which includes two parallel rods 211. The two parallel rods 211 allow the outer side of the first box frame 21 to form a plane that can support the side panels. The rods 211 can be hollow rods, each of which is provided with a through hole 2111. There are at least two through holes 2111, and the two through holes 2111 are spaced apart along the length of the rods 211. There are at least two bolts 231 and nuts 232 to enhance the stability of the first box frame 21 and the second box frame 22 after connection. Figure 14 As shown, two adjacent rods in the same plane are connected by a corner connecting sleeve 213, wherein the corner connecting sleeve is a prior art. Specifically, the ends of the rods are inserted into the corner connecting sleeve 213. Of course, the adjacent rods can also be directly connected.

[0106] The second box frame 22 has the same structure as the first box frame 21. During production, there are fewer types of parts. During assembly, there is no need to distinguish the placement positions of the first box frame 21 and the second box frame 22. As long as the first box frame 21 and the second box frame 22 are placed side by side, the through holes 2111 on the first box frame 21 and the second box frame 22 can be aligned and connected, which is convenient for the bolts 231 to pass through, thereby improving production efficiency and assembly efficiency.

[0107] In one embodiment, see Figure 19 、 Figure 21A 、 Figure 21B and Figure 21C As shown, in order to prevent collision between the first box frame 21 and the second box frame 22, the fastener 23 also includes a sleeve 233. The sleeve 233 is sleeved on the outside of the bolt 231 and is located between the first box frame 21 and the second box frame 22. The material of the sleeve 233 can be plastic or rubber. By providing the sleeve 233, after tightening the bolt 231 and the nut 232, the first box frame 21 and the second box frame 22 can be separated by the sleeve 233, avoiding defects such as wear and noise caused by direct contact between the first box frame 21 and the second box frame 22. In addition, by providing the sleeve 233, a fixed gap can be formed between the first box frame 21 and the second box frame 22, see Figure 20 As shown, after at least a portion of the side surrounding portion 11 is bent inwardly, the bent portion can be placed between the gaps.

[0108] In one embodiment, the widened portion includes an end support member 241, which is arranged at one end of the bed box 2 in the longitudinal direction. The bed box 2 has two wide and high surfaces arranged opposite to each other along the longitudinal direction. Figure 10As shown, the two end faces of the bed box 2 in the YZ plane are the width and height faces; the end support member 241 has a flat surface 2411a, which is located on the side of one width and height face of the bed box 2 away from the other width and height face.

[0109] It should be understood that the width and height of the bed box 2 refers to the farthest surface of the bed box along its length direction.

[0110] When two adjacent rods in the same plane are connected by a corner connector 213, the width and height of the bed box are coplanar with the outer surface of the corner connector 213 parallel to the outer side of the first box frame. When two adjacent rods in the same plane are directly connected, the width and height of the bed box are the outer side surfaces of the first and second box frames that are opposite each other along their length.

[0111] By setting the end support member 241, the part of the cover body 1 located at this position can be supported, that is, the end support member 241 can work together with the rod portion 211 of the wide and high surfaces of the first box frame 21 and the second box frame 22 to provide sufficient support for the cover body 1, prevent the cover body 1 from sinking in, wrinkling, etc., and ensure that the overall appearance of the cover body 1 is smoother and more continuous.

[0112] In one embodiment, the end support member 241 includes a strip plate structure 2411, a first clip 2412 and a second clip 2413. The first clip 2412 and the second clip 2413 are both fixedly installed on the same side of the strip plate structure 2411. The first clip 2412 is detachably connected to the first box frame 21, and the second clip 2413 is detachably connected to the second box frame 22.

[0113] Exemplarily, the strip plate structure 2411 has a first surface and a second surface opposite to each other, see Figure 12 and Figure 14 As shown, the first surface of the strip plate structure 2411 is a flat surface 2411a, and the first clip 2412 and the second clip 2413 can be welded to the second surface of the strip plate structure 2411. When installing the end support member 241, the first clip 2412 and the second clip 2413 can be used to easily connect the end support member 241 to the first box frame 21 and the second box frame 22.

[0114] Exemplarily, the thickness of the strip-shaped plate structure 2411 is as small as possible to ensure that the flat surface 2411 a can be as close as possible to the width and height of the bed box 2 .

[0115] In other embodiments, the end support member 241 may also be a hollow flat tubular structure, which can reduce the weight of the bed box 2.

[0116] In one embodiment, see Figure 12 As shown, the first buckle 2412 and the second buckle 2413 are both U-shaped. The first buckle 2412 is connected to the frame in the width direction of the first box frame 21, and the second buckle 2413 is connected to the frame in the width direction of the second box frame 22.

[0117] Taking the first buckle 2412 as an example, see Figure 12 As shown, the first clip 2412 includes an integrally formed first clamping arm 2412a, a connecting section 2412b, and a second clamping arm 2412c. The first clamping arm 2412a and the second clamping arm 2412c are arranged opposite each other. The first clamping arm 2412a and the second clamping arm 2412c each have an inwardly constricted neck. The free ends of the first clamping arm 2412a and the second clamping arm 2412c form an opening that is larger than the neck. The first clamping arm 2412a and the second clamping arm 2412c have a certain degree of elastic deformation, which facilitates the direct installation of the end support 241 from the outside of the bed box 2 and ensures that the end support 241 is firmly fixed to the bed box 2. When the end support 241 needs to be removed, a slight force can be applied to directly pull the end support 241 off the frame.

[0118] In one embodiment, the number of end supports 241 is at least two, and the widened portion further includes at least one connecting rod 242 located between the two end supports 241. One end of the first box frame 21 and the second box frame 22 are connected through one of the end supports 241, and the other end of the first box frame 21 and the second box frame 22 are connected through the other end support 241.

[0119] In this embodiment, see Figure 13 As shown, there are two end supports 241 and multiple connecting rods 242. Multiple connecting rods 242 are spaced apart along the length direction of the bed box 2. One end of the connecting rod 242 is detachably connected to the rod portion 211 above the long side of the first box frame 21, and the other end of the connecting rod 242 is detachably connected to the rod portion 211 above the long side of the second box frame 22. Multiple connecting rods 242 and end supports 241 together form a support surface for the upper surface of the bed box 2, so as to facilitate placing a mattress on the upper surface of the bed box assembly to improve overall stability and comfort.

[0120] See also Figure 15As shown, both ends of the connecting rod 242 are provided with a U-shaped groove 2421 with the opening 120 facing downward. One of the U-shaped grooves 2421 is engaged with the rod portion 211 of the first box frame 21 near the long side of the second box frame 22, and the other U-shaped groove 2421 is engaged with the rod portion 211 of the second box frame 22 near the long side of the first box frame 21. During installation, the connecting rod 242 is installed directly downward from the top of the box body, and the connecting rod 242 is engaged with the rod portion 211 of the long side located at the top of the first box frame 21 and the second box frame 22.

[0121] When installing the connecting rod 242, the connecting rod 242 can be installed in a position colinear with the transverse support rod 212 on the upper surfaces of the first box frame 21 and the second box frame 22. In this case, the groove wall at the end of the U-shaped groove 2421 is provided with an avoidance notch to avoid the transverse support rod 212. The avoidance notch of the U-shaped groove 2421 can be locked onto the transverse support rod 212 to prevent the connecting rod 242 from sliding on the rod portion 211 on the long side along the length direction of the bed box.

[0122] Of course, the connecting rod 242 can also be staggered with the transverse support rod 212 .

[0123] During assembly, the two ends of the connecting rod 242 can be connected to the first box frame 21 and the second box frame 22 respectively to fix the positions of the first box frame 21 and the second box frame 22, and then the end support 241 can be installed. The first clip 2412 and the second clip 2413 can be used to easily achieve the connection between the end support 241 and the first box frame 21 and the second box frame 22.

[0124] In other embodiments, the flat surface 2411a may also be coplanar with the width and height of the bed box 2, which can further enhance the flatness and continuity of the appearance of the bed box assembly.

[0125] For example, see Figures 22 to 24 As shown, the end support member includes a U-shaped plate structure, and the U-shaped plate structure includes a first connecting plate 2414, a second connecting plate 2415 and a support plate 2416. The first connecting plate 2414 and the second connecting plate 2415 are relatively arranged at both ends of the support plate 2416, and the flat surface 2411a is the surface of the support plate 2416 away from the first connecting plate 2414 and the second connecting plate 2415; the first connecting plate 2414 is provided with a third clip 2417, and the second connecting plate 2415 is provided with a fourth clip 2418. The third clip 2417 is clipped to the frame of the first box frame 21 in the length direction, and the fourth clip 2418 is clipped to the frame of the second box frame 22 in the length direction.

[0126] See also Figure 23As shown, the flat surface 2411a is coplanar with the outer surface of the corner connecting sleeve 213 parallel to the outer side surface of the first box frame.

[0127] It should be noted that, when the bed box 2 includes three or more box frames, the number of the end supports 241 will also increase accordingly to ensure that two adjacent box frames are connected together.

[0128] This embodiment also provides a bed, comprising a bed box and a cover 1 provided in this embodiment. The bed provided in this embodiment, by utilizing the cover 1 provided in this embodiment, can accommodate bed boxes of varying sizes. The bed boxes of varying sizes can be adjustable bed boxes 2, which adjust their size through self-adjustment, or can be directly replaced with different sized bed boxes.

[0129] For example, when the cover body 1 is placed on a large-sized bed box, the side surrounding parts 11 can just be wrapped around the outer periphery of the bed box; when the cover body 1 is placed on a small-sized bed box, at least part of the side surrounding parts 11 are bent inward so that the circumference of the side surrounding parts 11 is reduced to adapt to the circumference of the small-sized bed box, thereby wrapping around the outer periphery of the small-sized bed box.

[0130] This embodiment also provides a bed, including the bed box assembly provided by this embodiment. Because the bed provided by this embodiment utilizes the bed box assembly provided by this embodiment, the side panels 11 can wrap around the outer periphery of the bed box regardless of the circumference of the bed box, thereby ensuring the bed's aesthetic appearance. Specifically, the cover 1 can be directly mounted on a large-sized bed box; when the cover 1 is mounted on a small-sized bed box, at least a portion of the side panels 11 is bent inward, reducing the circumference of the side panels 11 to accommodate the circumference of the small-sized bed box, thereby wrapping around the outer periphery of the small-sized bed box.

[0131] In one embodiment, the bed further comprises a bed frame, which is located below the bed box 2 and is used to support the bed box 2. Support legs are provided below the bed frame.

[0132] In one embodiment, the bed further includes supporting legs, which can be directly installed under the bed box 2. In this case, the bed frame can be omitted.

[0133] In one embodiment, the bed further comprises a mattress, which is placed above the bed box 2 .

[0134] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
