[0041] The following will be combined with the attached embodiment of the present invention Figure 1-8 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figure 1-3 As shown, a foldable backrest structure is proposed, which comprises a backrest body, wherein the backrest body comprises a foldable backrest board 1 .

[0043] The support surface of the backrest board 1 is covered with sponge 6, and is provided with a backrest surface cover 4 covering the sponge 6. The folding hinge of the backrest board 1 is configured as a flexible connection structure.

[0044] In the packaging state, the backrest board 1 is folded to form a rectangular flat packaging structure; in the use state, the backrest board 1 is unfolded to form a plate-like structure.

[0045] As a preferred embodiment, Figure 2 , 3 As shown, the backrest board 1 is divided into an upper backrest board 1a and a lower backrest board 1b connected by a flexible connection structure, both of which are rectangular boards. In the packaging state, the backrest board 1 is folded in half so that the supporting side of the upper backrest board 1a and the supporting side of the lower backrest board 1b are relatively close to each other.

[0046] The sponge 6 is formed as a whole and covers the support surfaces of the upper backrest plate 1a and the lower backrest plate 1b at the same time. The flexible connection structure is a flexible handle member 5 (usually a cloth) connected to the inner surface of the backrest cover 4. The sponge 6 is provided with a through seam 6a (such as Figure 5 As shown), the through-slit 6a is opposite to the gap between the upper backrest plate 1a and the lower backrest plate 1b, and the handle member 5 penetrates the through-slit 6a of the sponge 6 toward the back side of the backrest plate 1 and is connected to the back of the upper backrest plate 1a or the lower backrest plate 1b.

[0047] like Figure 3 , 4As shown, when packaging, the backrest board 1 is folded in half, so that the backrest cover 4 is also folded in half and relatively fit, and the sponge 6 of the upper backrest board 1a and the sponge 6 of the lower backrest board 1b are relatively pressed (a part of the sponge 6 protrudes outward), forming a flexible contact effect, so that the flat packaging structure formed after folding has certain shock-absorbing performance.

[0048] The backrest body also includes two backrest columns 2 that support the ground when in use and are removed when packed. In the use state, the back of the backrest board 1 is detachably connected to the backrest columns 2, that is, the backrest columns 2 are detachably fixedly connected to the back of the upper backrest board 1a and the back of the lower backrest board 1b at the same time; Figure 2 As shown, an upper support bar 3 is fixedly connected to the upper side of the back of the upper backrest plate 1a. The upper support bar 3 extends horizontally in the left-right direction, and the upper ends of the two backrest columns 2 support the upper support bar 3.

[0049] like Figure 6 As shown, the backrest column 2 includes a hard column body 2a and a flexible column cloth cover 2b, the column cloth cover 2b wraps the column body 2a, and is sewn according to the shape of the column body 2a; the column body 2a is configured as a straight hollow pipe fitting (such as a rectangular steel pipe or other types of pipe fittings) as a whole, and a pipe plug 2c made of a flexible material is sealed and inserted at its lower end, and the pipe plug 2c can be a structure made of rubber, which is used to seal the lower end of the column body 2a.

[0050] One end of the column cloth cover 2b is set as an open end, and the other end is set as a closed end. The length of the column cloth cover 2b is slightly longer than the length of the column body 2a.

[0051] During assembly, put the column cloth cover 2b on the column body 2a, and insert the column body 2a from the open end of the column cloth cover 2b until the lower end of the column body 2a presses against the closed end of the column cloth cover 2b. Since the length of the column cloth cover 2b is slightly longer than the length of the column body 2a, the fabric of the open end of the column cloth cover 2b exceeds the pipe opening of the column body 2a at this time. The excess part of the column cloth cover 2b can be stuffed into the pipe opening, and then the pipe plug 2c can be stuffed into the pipe opening of the column body 2a, and the column cloth cover 2b can be sealed at the same time; the packaging of the backrest column 2 is now completed.

[0052] The backrest column 2 of this embodiment has higher strength than the traditional wooden backrest column, and the assembly process is simpler without the need to use glue, nail guns, installation tools, etc.

[0053] Compared with the iron columns on the market, this embodiment can flexibly change the surface appearance by replacing the fabric (column cloth cover 2b), and has better design plasticity.

[0054] like Figure 7 As shown, the above-mentioned pipe plug 2c includes:

[0055] An exposed portion 201, which is exposed outside the column body 2a, is used to contact the ground and support the column body 2a;

[0056] A plurality of lateral protrusions 202 laterally surround the exposed portion 201, a portion of the column cloth cover 2b is folded into the inner cavity of the column body 2a from the end opening of the column body 2a, and is pressed against the inner wall of the column body 2a by the lateral protrusions 202;

[0057] The hollow cavity 203 has an open structure on one side and faces the inner cavity of the column body 2 a . The hollow cavity 203 corresponds to the distribution area of ​​the lateral protrusions 202 .

[0058] After the pipe plug 2c is inserted, the lateral pressure generated by the lateral protrusion 202 is used to press a part of the column cloth sleeve 2b against the inner wall of the column body 2a, and the end of the column body 2a presses against the exposed part 201 to form a seal.

[0059] This patent also proposes a soft-packed bed structure, which is equipped with the above-mentioned foldable backrest structure. The soft-packed bed includes:

[0060] Two side panels 8 detachably connected to the backrest body and distributed on the left and right sides, the side panels 8 extending horizontally along the length of the bed, and the two side panels 8 are detachably fixedly connected to the two backrest columns 2 respectively;

[0061] The bottom panel 7 is located at the foot side of the bed, and the two ends of the bottom panel 7 are detachably fixedly connected to the two side panels 8 and are perpendicular to each other, thereby forming a rectangular bed structure;

[0062] A plurality of ribs 10 are spaced apart along the length of the bed, and the ribs 10 extend horizontally along the width of the bed. The ribs 10 are steel pipes, replacing traditional solid wood boards, which are stronger and cheaper.

[0063] Two wooden rib strip mounting rods 9, which extend along the length direction of the side panels 8 and are fixedly connected to the inner side of the side panels 8, and the two ends of the rib strip 10 are detachably connected to the two rib strip mounting rods 9;

[0064] The cross brace 11 is detachably assembled from two crisscrossed rods, one of which (the longitudinal rod) extends horizontally along the length of the bed and is located in the middle of the width of the bed, and the other rod (the transverse rod) is mounted on the longitudinal rod, which is located in the middle of the length of the bed. The longitudinal rod supports the ribs 10.

[0065] Among them, the backrest board 1 is connected to the backrest column 2 by screws, and the side panel 8 and the bottom panel 7 are respectively connected to the horizontal bar and the longitudinal bar of the cross support rod 11 by bolts. After the backrest column 2 and the backrest board 1 are assembled, the two backrest columns 2 are respectively connected to the two side panels 8 to complete the assembly of the main frame.

[0066] like Figure 8 As shown, the rib bar installation rod 9 has a plurality of rib bar installation grooves 9a with openings facing upwards, and the rib bar installation grooves 9a correspond to the rib bar 10 one by one. The rib bar 10 is detachably inserted into the rib bar installation grooves 9a, and the installation noise is lower. The rib bar installation grooves 9a are used to locate the installation position of the rib bar 10, and no fasteners are required. The installation is convenient and the strength of the installation structure can be guaranteed. After the main frame is assembled, the rib bar 10 is clamped in the rib bar installation grooves 9a of the rib bar installation rod 9 to complete the product assembly. This step does not require the installation of screws, which is quick and convenient.

[0067] A specific installation method is proposed for the foldable backrest structure, which includes the following steps:

[0068] S1. Fix the upper backrest plate 1a and the lower backrest plate 1b on the workbench, and reserve a certain gap between the upper backrest plate 1a and the lower backrest plate 1b;

[0069] S2, spread the sponge 6 on the supporting surfaces of the upper backrest plate 1a and the lower backrest plate 1b, and cut a through seam 6a with a knife at the position of the sponge 6 facing the gap between the upper backrest plate 1a and the lower backrest plate 1b, so that the through seam 6a runs through the front and back;

[0070] S3, wrap the upper backrest plate 1a, the lower backrest plate 1b and the sponge 6 with the backrest cover 4, and drive the handle member 5 to pass through the through slit 6a backward during wrapping;

[0071] S4, tighten the handle member 5 and fix the handle member 5 on the back of the upper backrest plate 1a or the lower backrest plate 1b.

[0072] Among them, in step S4, with the tightening action of the handle piece 5, the handle piece 5 drives the backrest cover 4 to tighten at the position of the handle piece 5, driving the portion of the sponge 6 facing the gap between the upper backrest plate 1a and the lower backrest plate 1b to deform, forming a concave shape. At the same time, the concave portion of the sponge 6 fills the gap between the upper backrest plate 1a and the lower backrest plate 1b, forming a backrest groove 4a on the supporting side of the backrest plate 1.

[0073] By adjusting the distance between the upper backrest plate 1a and the lower backrest plate 1b, the thickness of the sponge 6, and the length of the handle piece 5 of the backrest surface cover 4, different concave shapes can be formed on the backrest surface.

[0074] The flexible connection between the upper backrest plate 1a and the lower backrest plate 1b can be achieved through the sponge 6 and the backrest cover 4, which is a flexible connection relationship; therefore, the upper backrest plate 1a and the lower backrest plate 1b can be folded and packaged during packaging, thereby saving packaging space. At the same time, it is more convenient for users to assemble. They only need to unfold the upper backrest plate 1a and the lower backrest plate 1b, and then use the backrest column 2 to fix the upper backrest plate 1a and the lower backrest plate 1b together.

[0075] The entire soft-pack bed is configured as a separable and disassembled structure, which is disassembled and reassembled into a rectangular installation structure during packaging (similar to several previous patents of the applicant), and has a small packaging size, which can meet packaging and transportation requirements.
