DETAILED DESCRIPTION

[0055] The technical solution of the present disclosure will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present disclosure.

[0056] In the description of the present disclosure, it should be noted that, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present disclosure and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present disclosure. In addition, if the terms "first", "second", "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0057] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0058] The orientation definition in this embodiment is: Figure 1 and Fig.10 As shown, the arrow direction X represents the length direction of the bed box and the length direction of the side enclosure mounted on the bed box, the arrow direction Y represents the width direction of the bed box and the width direction of the side enclosure 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 enclosure.

[0059] See also Figures 1 to 24 As shown, this embodiment provides a cover body 1, which includes a side surrounding portion 11, which is used to wrap around the outer periphery of the bed box 2, and at least part of the side surrounding portion 11 can be bent inward to reduce the circumference of the side surrounding portion 11.

[0060] The cover body 1 provided in this embodiment can be used on bed boxes of different sizes (for example, a large-sized bed box and a small-sized bed box). When in use, the cover body 1 is placed on the large-sized bed box, and the side surrounding portion 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 surrounding portion 11 is bent inwardly so that the circumference of the side surrounding portion 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.

[0061] 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 wrap around the outer peripheral side of the bed box 2 .

[0062] It should be understood that bed boxes of different sizes refer to bed boxes with different circumferences, which may be different in width, different in length, or different in width and length. A large-sized bed box has a first circumference, and a small-sized bed box has a second circumference, and the first circumference is greater than the second circumference. Normally, when the cover body 1 is mounted on a large-sized bed box, at least a portion of the side surrounding portion 11 does not need to be bent, so that the effect of the side surrounding portion 11 being wrapped around the outer circumference of the bed box can be achieved. When the cover body 1 is mounted on a small-sized bed box, at least a portion of the side surrounding portion 11 is bent inwardly, so that the circumference of the side surrounding portion 11 is reduced to adapt to the circumference of the small-sized bed box, thereby wrapping around the outer circumference of the small-sized bed box.

[0063] In one embodiment, the side surrounding portion 11 is a flexible annular structure. Figure 1 As shown, the height of the flexible annular structure along 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.

[0064] It should be understood that the flexible annular structure in this embodiment means that the side surrounding portion 11 has a circumferentially closed space, rather than a flexible belt. Before the cover is installed on the bed box 2, the outline of the closed space is not determined. After the cover is installed on the bed box 2, the outline of the closed space is adapted to the outline of the outer peripheral side of the bed box 2.

[0065] 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 sliding off the bed box 2.

[0066] Exemplarily, the tightening member may be an elastic band or a drawstring.

[0067] In one embodiment, see Figure 3 As shown, in order to prevent the side enclosure 11 from sliding off the bed box 2 , the cover body 1 further includes a top cover 12 , which is connected to the side enclosure 11 and has an opening 120 corresponding to the bendable portion of the side enclosure 11 .

[0068] 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 only provided on the second annular edge 112 .

[0069] By providing the opening 120 on the top cover 12, a space for avoiding can be reserved, and when the side surrounding part 11 is bent inward, it will not be folded to the top cover 12, thereby not affecting the flatness of the top cover, ensuring a beautiful appearance. At the same time, the opening 120 is convenient for the bending operation.

[0070] 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.

[0071] Illustratively, the top cover portion 12 may be sewn onto the side surrounding portion 11 .

[0072] 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, and 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.

[0073] Exemplarily, the first top cover portion 121 is in a rectangular shape, and has a first long side and a second long side opposite to each other, and a first short side and a second short side 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 opposite to each other, and a third short side and a fourth short side 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 is substantially parallel to the fourth long side, and the space between the second long side and the fourth long side forms an opening 120.

[0074] 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.

[0075] 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 , and the shielding portion 13 is detachably connected to the second top cover portion 122 to cover the opening 120 .

[0076] For example, the shielding portion 13 is integrally formed with the first top cover portion 121, and the shielding portion 13 can be tilted relative to the side surrounding portion 11. When the shielding portion 13 is lifted, the opening 120 is exposed, which facilitates the inward bending of the side portion. When the shielding portion 13 falls, it can be detachably connected to the second top cover portion 122, thereby covering the opening 120, ensuring a beautiful appearance and consistency.

[0077] In one embodiment, a connecting portion 131 is disposed on the lower surface of the shielding portion 13 , and a connecting mating portion 1221 is disposed 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 .

[0078] Exemplarily, the connection portion 131 and the connection matching portion 1221 may be Velcro, snap fasteners, or magnetic components that attract each other.

[0079] The connecting portion 131 and the shielding portion 13 may be connected together by sewing or bonding, and the connecting matching portion 1221 and the second top cover portion 122 may be connected together by sewing or bonding.

[0080] See also Figure 6 and Figure 7As 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 .

[0081] In one embodiment, a fixing piece is disposed on the inner surface of the side surrounding portion 11 , 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 peripheral side of the bed box 2 .

[0082] 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 peripheral side of the bed box 2 of a smaller size.

[0083] In a possible design, the fixing member includes a strip, and the strip is used to be connected to the bed box 2 to pull the portion of the side surrounding portion 11 that exceeds the bed box 2 toward the inside of the bed box 2 .

[0084] 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 surround 11 that exceeds the bed box 2 toward the inside of the bed box 2.

[0085] The number of the annular strip 113 may be one or more. Figure 8 As shown, two groups of annular strips are symmetrically arranged on the inner surface of the side surrounding portion 11 , each group includes two annular strips 113 , and the two annular strips 113 are arranged at intervals along the height of the side surrounding portion 11 .

[0086] In other embodiments, each group includes four annular strips 113, wherein two annular strips 113 are arranged at positions close to the first annular edge 111 of the side surrounding portion 11, and the other two annular strips 113 are arranged at positions close to the second annular edge 112 of the side surrounding portion 11. Fig.21 As shown, the annular strip 113 may also be a drawstring arranged around the side enclosure 11. By pulling the drawstring, the side enclosure 11 can be tightened to wrap the outer circumference of the bed box 2, and then the free end of the drawstring is sleeved on the butterfly nut.

[0087] It should be noted that a group of annular strips may also be provided on the inner surface of the side surrounding portion 11 .

[0088] 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 surround 11 that exceeds the bed box 2 toward the inside of the bed box 2 .

[0089] 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, wherein 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.

[0090] This method can achieve the fixation of the side enclosure 11 itself without the need for a bed box.

[0091] Exemplarily, the first adhesive member 114a and the second adhesive member 114b may be Velcro.

[0092] See also Fig. 9 As shown, the present embodiment further provides a bed box assembly, including a bed box 2 and a cover body 1 provided in the present embodiment, the circumference of the bed box 2 is adjustable, the side surrounding portions 11 are wrapped around the outer circumference of the bed box 2, and at least part of the side surrounding portions 11 can be bent inward to reduce the circumference of the side surrounding portions 11 to match the circumference of the bed box 2.

[0093] The bed box assembly provided in this embodiment uses the cover body 1 provided in this embodiment, so that when the circumference of the bed box 2 is different, the side surrounding parts 11 can be wrapped around the outer circumference of the bed box 2. Specifically, the cover body 1 can be directly covered on the large-sized bed box 2; when the cover body 1 is covered on the small-sized bed box 2, at least part of the side surrounding parts 11 is bent inwardly, so that the circumference of the side surrounding parts 11 is reduced to adapt to the circumference of the small-sized bed box 2, so as to be wrapped around the outer circumference of the small-sized bed box 2.

[0094] 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 .

[0095] In one embodiment, see Fig.10 As shown, the bed box 2 includes a first box frame 21, a second box frame 22 and a widened portion, and the widened portion is detachably connected between the first box frame 21 and the second box frame 22 so that the width of the bed box 2 is adjustable.

[0096] See also Fig.10 As 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 Fig.16As shown, after the widened portion is separated from the first box frame 21 and the second box frame 22, the first box frame 21 and the second box frame 22 are placed side by side to form a smaller width bed box 2. When it is a smaller width bed box, the first box frame 21 and the second box frame 22 are arranged side by side, and there is a slight gap between the first box frame 21 and the second box frame 22. When at least part of the side surrounding portion 11 is bent inward, the bent portion can be placed between the gaps.

[0097] It should be noted that the structures of the first box frame 21 and the second box frame 22 are prior art.

[0098] 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 by a fastener 23 when the widened portion is separated from the first box frame 21 and the second box frame 22 .

[0099] In addition, by providing the fastener 23 , it is also convenient to connect the strips on the side surrounding portion 11 to the fastener 23 .

[0100] 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 with the nut 232 .

[0101] For example, see Fig.19 and Fig. 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 easily mounted on the head of the butterfly bolt and the butterfly nut to pull the part of the side surround 11 that exceeds the circumference of the bed box 2 toward the inside of the bed box 2. At the same time, the annular strip 113 can be effectively prevented from falling off.

[0102] See also Fig.21 As shown, when the annular strip 113 is a drawstring arranged around the side enclosure 11, the side enclosure 11 can be tightened by pulling the drawstring to wrap the outer circumference of the bed box 2, and then the free end of the drawstring is sleeved on the head of the butterfly bolt and the butterfly nut.

[0103] For example, taking the first box frame 21 as an example, see Fig.11As shown, the first box frame 21 includes a rectangular parallelepiped frame structure assembled from a plurality of rods. The first box frame 21 has two opposite long sides, each of which includes two parallel rods 211. The two parallel rods 211 can form a plane on the outside of the first box frame 21 that can support the side enclosure. The rods 211 can be hollow rods, each of which is provided with a through hole 2111. The number of through holes 2111 is at least two. The two through holes 2111 are spaced apart along the length direction of the rods 211. The number of bolts 231 and nuts 232 is at least two, so as to enhance the stability of the first box frame 21 and the second box frame 22 after being connected. See Fig.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 end of the rod is inserted into the corner connecting sleeve 213, and of course, the adjacent two rods can also be directly connected.

[0104] 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.

[0105] In one embodiment, see Fig.19 and Fig.21 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, and the sleeve 233 is sleeved on the outside of the bolt 231, and the sleeve 233 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 the bolt 231 and the nut 232 are tightened, the first box frame 21 and the second box frame 22 can be separated by the sleeve 233, thereby 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 Fig. 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.

[0106] In one embodiment, the widened portion includes an end support member 241, which is disposed at one end of the bed box 2 in the length direction. The bed box 2 has two wide and high surfaces disposed opposite to each other along the length direction thereof. Fig.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.

[0107] It should be understood that the wide and high surface of the bed box 2 refers to the farthest surface of the bed box along the length direction thereof.

[0108] When two adjacent rods in the same plane are connected by the corner connecting sleeve 213, the width and height surface of the bed box is coplanar with the outer surface of the corner connecting sleeve 213 parallel to the outer side surface of the first box frame. When two adjacent rods in the same plane are directly connected, the width and height surface of the bed box is the outer side surfaces of the first box frame and the second box frame that are oppositely arranged along their length direction.

[0109] 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.

[0110] 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.

[0111] Exemplarily, the strip plate structure 2411 has a first surface and a second surface opposite to each other, see Fig.12 and Fig.14 As shown, the first surface of the strip plate structure 2411 is a flat surface 2411a, and the first buckle 2412 and the second buckle 2413 can be welded to the second surface of the strip plate structure 2411. When installing the end support member 241, the first buckle 2412 and the second buckle 2413 can be used to easily connect the end support member 241 with the first box frame 21 and the second box frame 22.

[0112] Exemplarily, the thickness of the strip plate structure 2411 is as small as possible to ensure that the flat surface 2411a can be as close as possible to the width and height of the bed box 2.

[0113] In other embodiments, the end support member 241 may also be a hollow flat tube structure, which can reduce the weight of the bed box 2.

[0114] In one embodiment, see Fig.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 of the first box frame 21 in the width direction, and the second buckle 2413 is connected to the frame of the second box frame 22 in the width direction.

[0115] Taking the first buckle 2412 as an example, for example, see Fig.12 As shown, the first buckle 2412 includes a first clamping arm 2412a, a connecting section 2412b and a second clamping arm 2412c which are integrally formed. The first clamping arm 2412a and the second clamping arm 2412c are arranged opposite to each other. The first clamping arm 2412a and the second clamping arm 2412c both have an inwardly contracted neck. The free ends of the first clamping arm 2412a and the second clamping arm 2412c form an opening, the size of the opening is larger than the size of the neck. The first clamping arm 2412a and the second clamping arm 2412c have a certain elastic deformation, which makes it convenient to directly install the end support 241 from the outside of the bed box 2 and make the end support 241 clamped on the bed box 2. When it is necessary to disassemble the end support 241, a slight force is applied to directly pull the end support 241 off the frame.

[0116] In one embodiment, the number of end supports 241 is at least two, and the widened portion also 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.

[0117] In this embodiment, see Fig.13 As shown, there are two end supports 241 and a plurality of connecting rods 242, and the plurality of 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. The plurality of connecting rods 242 and the 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 and improve the overall stability and comfort.

[0118] See also Fig.15As shown, both ends of the connecting rod 242 are provided with U-shaped grooves 2421 with openings 120 facing downwards, one of the U-shaped grooves 2421 is clamped on the rod portion 211 of the first box frame 21 close to the long side of the second box frame 22, and the other U-shaped groove 2421 is clamped on the rod portion 211 of the second box frame 22 close to the long side of the first box frame 21. During installation, the connecting rod 242 is directly installed downward from the top of the box, and the connecting rod 242 is clamped with the rod portion 211 of the long side of the first box frame 21 and the second box frame 22 located at the top.

[0119] When installing the connecting rod 242, the connecting rod 242 can be installed at a position colinear with the transverse support rod 212 on the upper surface of the first box frame 21 and the second box frame 22. At this time, the groove wall at the end of the U-shaped groove 2421 is provided with an escape notch to escape the transverse support rod 212. The escape notch of the U-shaped groove 2421 can be clamped on 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.

[0120] Of course, the connecting rod 242 can also be arranged in a staggered manner with the transverse support rod 212 .

[0121] During assembly, the two ends of the connecting rod 242 can be first 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.

[0122] 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.

[0123] For example, see Figure 22 to Figure 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 buckle 2417, and the second connecting plate 2415 is provided with a fourth buckle 2418. The third buckle 2417 is clamped with the frame of the first box frame 21 in the length direction, and the fourth buckle 2418 is clamped with the frame of the second box frame 22 in the length direction.

[0124] See also Fig.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.

[0125] 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.

[0126] The present embodiment further provides a bed, comprising a bed box and a cover body 1 provided in the present embodiment. The bed provided in the present embodiment can be adapted to bed boxes of different sizes due to the use of the cover body 1 provided in the present embodiment. The bed boxes of different sizes here can be bed boxes 2 with adjustable sizes, which can change their sizes by adjusting themselves, or can be directly replaced with bed boxes of different sizes.

[0127] For example, when the cover body 1 is placed on a large-sized bed box, the side surrounding portion 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 portion 11 is bent inward so that the circumference of the side surrounding portion 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.

[0128] The present embodiment also provides a bed, including the bed box assembly provided in the present embodiment. The bed provided in the present embodiment uses the bed box assembly provided in the present embodiment, so that when the circumference of the bed box is different, the side surrounding parts 11 can be wrapped around the outer circumference of the bed box, thereby ensuring the beautiful appearance of the bed. Specifically, the cover body 1 can be directly covered on a large-sized bed box; when the cover body 1 is covered on a small-sized bed box, at least part of the side surrounding parts 11 is bent inwardly, 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 circumference of the small-sized bed box.

[0129] 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 arranged below the bed frame.

[0130] In one embodiment, the bed further comprises supporting legs, which can be directly installed under the bed box 2. In this case, the bed frame can be omitted.

[0131] In one embodiment, the bed further comprises a mattress, which is placed above the bed box 2 .
