[0035] The following is a combination of the appended examples 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. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0036] like Figure 1-3 As shown, a foldable backrest structure is proposed, which includes a backrest body, and the backrest body includes a foldable backrest board 1.

[0037] 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.

[0038] 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-shaped structure.

[0039] 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 are rectangular boards. In the packaged 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.

[0040] The sponge 6 is formed as a whole and covers the support surface of the upper backrest plate 1a and the lower backrest plate 1b at the same time. The flexible connection structure is a flexible handle 5 (usually made of 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 passes through 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.

[0041] like Figure 3 、 4 As 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 together, and the sponge 6 of the upper backrest board 1a and the sponge 6 of the lower backrest board 1b are pressed against each other (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.

[0042] 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 and right directions, and the upper ends of the two backrest columns 2 support the upper support bar 3.

[0043] like Figure 6As 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 tube (such as a rectangular steel tube or other types of tubes), and a pipe plug 2c made of a flexible material is sealed and inserted at its lower end. The pipe plug 2c can be a structure made of rubber, which is used to seal the lower end of the column body 2a.

[0044] 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.

[0045] 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. The excess part of the column cloth cover 2b can be stuffed into the pipe opening, and then the pipe plug 2c is stuffed into the pipe opening of the column body 2a, and the column cloth cover 2b is sealed at the same time; the packaging of the backrest column 2 is completed at this point.

[0046] Compared with traditional wooden backrest columns, the backrest column 2 of this embodiment has higher strength and a simpler assembly process, without the need for glue, nail guns, installation tools, etc.

[0047] 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.

[0048] like Figure 7 As shown, the pipe plug 2c includes:

[0049] The exposed portion 201 is exposed outside the column body 2a and is used to contact the ground and support the column body 2a;

[0050] 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.

[0051] 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 .

[0052] After the pipe plug 2c is inserted, the lateral pressure generated by the lateral protrusion 202 is used to press a portion of the column cloth cover 2b against the inner wall of the column body 2a, and the end of the column body 2a presses against the exposed portion 201 to form a seal.

[0053] This patent also proposes a soft-pack bed structure, which is equipped with the above-mentioned foldable backrest structure. The soft-pack bed includes:

[0054] 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;

[0055] The bottom panel 7 is located at the foot of the bed. 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.

[0056] A plurality of ribs 10 are spaced apart along the length of the bed and extend horizontally along the width of the bed. The ribs 10 are made of steel pipes, replacing traditional solid wood boards, which are stronger and cheaper.

[0057] Two wooden rib strip mounting rods 9, which extend along the length of the side panels 8 and are fixedly connected to the inner side of the side panels 8. The two ends of the rib strip 10 are detachably connected to the two rib strip mounting rods 9;

[0058] The cross brace 11 is composed of two crisscross rods that can be detachably assembled. One rod (longitudinal rod) extends horizontally along the length of the bed and is located in the middle of the width of the bed. The other rod (transverse rod) is mounted on the longitudinal rod, and the transverse rod is located in the middle of the length of the bed. The longitudinal rod supports the ribs 10.

[0059] 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 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.

[0060] like Figure 8 As shown, the rib bar mounting rod 9 has a plurality of rib bar mounting grooves 9a with upward openings. The rib bar mounting grooves 9a correspond one to one with the rib bar 10. The rib bar 10 is detachably inserted into the rib bar mounting grooves 9a, which reduces installation noise. The rib bar mounting grooves 9a are used to locate the installation position of the rib bar 10, eliminating the need for any fasteners, making installation easy and ensuring the strength of the installed structure. After completing the assembly of the main frame, the rib bar 10 is clamped into the rib bar mounting grooves 9a of the rib bar mounting rod 9 to complete the product assembly. This step does not require installation screws and is quick and convenient.

[0061] A specific installation method is proposed for the foldable backrest structure, which includes the following steps:

[0062] 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;

[0063] S2. Place the sponge 6 on the support surfaces of the upper backrest plate 1a and the lower backrest plate 1b, and cut a through seam 6a with a knife at a position on the sponge 6 that is opposite to the gap between the upper backrest plate 1a and the lower backrest plate 1b. The through seam 6a runs through the front and back.

[0064] S3. Wrap the upper backrest plate 1a, the lower backrest plate 1b and the sponge 6 with the backrest cover 4, driving the handle 5 backward through the through-slit 6a during wrapping;

[0065] S4. Tighten the handle 5 and fix the handle 5 on the back of the upper backrest plate 1a or the lower backrest plate 1b.

[0066] 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 where the handle piece 5 is located, driving the part 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 part 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.

[0067] 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 5 of the backrest cover 4, different concave shapes can be formed on the backrest surface.

[0068] 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.

[0069] The entire soft-pack bed is configured as a detachable and disassembled structure, which is disassembled and reassembled into a rectangular installation structure during packaging (similar to several previous patents of the applicant). The packaging size is small and can meet packaging and transportation requirements.
