The water bag is made of rubber or a new generation of polymer composite materials and filled with water.

[0075] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0076] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0077] The inventor of the present application provides an adaptive pressure bearing method, which does not require the design of an additional receiving device that forms a communicating vessel with the pressure bearing body in addition to the pressure bearing body such as a water bag, but designs the pressure bearing part of the pressure bearing body so that it can achieve adaptive pressure adjustment by itself. The adaptive pressure bearing method is described in detail below.

[0078] The adaptive pressure-bearing method includes constructing a flexible pressure-bearing body, so that the flexible pressure-bearing body includes an active part and an inert part, and the expandable amplitude of the active part is greater than the expandable amplitude of the inert part. The expandable amplitude described in this application refers to the maximum offset of the inert part / active part of the flexible pressure-bearing body from the initial position under the maximum rated load. When the force-applying object acts on the pressure-bearing body, both the active part and the inert part of the pressure-bearing body are deformed, the expansion amplitude of the active part is large, the expansion amplitude of the inert part is small, the pressure-bearing surface of the active part and the pressure-bearing surface of the inert part are different in the sunken position, and finally the surface stress of the pressure-bearing surface of the active part is close to the surface stress of the pressure-bearing surface of the inert part, and the surface of the force-applying object in contact with the pressure-bearing surface of the active part and the surface of the pressure-bearing surface of the inert part obtains an indifferent supporting force. From the above, it can be seen that the flexible pressure-bearing body supports the force-applying object through the differentiated position change of the active part and the inert part, so that the force-applying object obtains an indifferent supporting effect.

[0079] In a method for constructing a pressure-bearing body, the pressure-bearing body is a first pressure-bearing body 100. The first pressure-bearing body 100 is stretched over a part or all of the area above the open side of an open cavity. The first pressure-bearing body 100 includes a first flexible region and a second flexible region having different surface stresses. The surface stress of the first flexible region is greater than the surface stress of the second flexible region. The first flexible region with large surface stress constitutes an inert portion, and the second flexible region with small surface stress constitutes an active portion.

[0080] The first pressure-bearing body 100 may be constructed in various ways:

[0081] 1. See Figure 2 The two strips with different surface stresses are stretched and flattened on an open cavity. The two strips with different surface stresses are arranged adjacent to each other, and the strips with the same surface stress are arranged alternately. The strip with large surface stress constitutes the first flexible area 110 of the first pressure-bearing body 100, and the strip with small surface stress constitutes the second flexible area 120 of the first pressure-bearing body 100.

[0082] 2. See Figure 3 , multiple strips with the same surface stress are stretched and flattened on an open cavity, and the strips are arranged at intervals. The strips constitute the first flexible area 110 of the first pressure-bearing body 100, and the pores between the strips constitute the second flexible area 120 of the first pressure-bearing body 100.

[0083] 3. See Figure 4 The flexible cloth-like material is stretched and flattened on an open cavity, and a plurality of through holes having a predetermined shape, such as an oblong, circular, elliptical or polygonal shape, are provided on the flexible cloth-like material. The area through the through holes constitutes the second flexible area 120 of the first pressure-bearing body 100, and the flexible cloth around the through holes constitutes the first flexible area 110 of the first pressure-bearing body 100.

[0084] 4. See Figure 5 The first pressure-bearing body 100 includes a first pressure-bearing plane 111 and a second pressure-bearing plane 112. The first pressure-bearing plane 111 is stretched. The first pressure-bearing plane 111 can be a piece of integral flexible cloth, on which a plurality of through holes penetrating the first pressure-bearing plane 111 are opened. The first pressure-bearing plane 111 can also be a plurality of belt-shaped objects with the same surface stress spaced a predetermined distance apart and stretched. Figure 5 The gaps between the strips shown in the figure can also be considered as square through holes on the first pressure-bearing plane 111. The second pressure-bearing plane 112 is another piece of integral flexible fabric, and its surface stress can be the same as or different from the surface stress of the first pressure-bearing plane 111. The second pressure-bearing plane 112 is superimposed on the first pressure-bearing plane 111, and the through holes on the first pressure-bearing plane 111 and the part in contact with the second pressure-bearing plane 112 together constitute the second flexible region 120 of the first pressure-bearing body 100, and the part of the first pressure-bearing plane 111 other than the through holes and the part in contact with the second pressure-bearing plane 112 together constitute the first flexible region 110 of the first pressure-bearing body 100.

[0085] 5. See Fig.16 , shows another construction method of the first pressure-bearing body, in which the flexible fabric is stretched and flattened as the first pressure-bearing body 100. Two cutouts 121 are provided on the flexible fabric. The area between the two cutouts 121, i.e., the flexible fabric within the dotted line, has a surface stress smaller than that of the area outside the dotted line due to the existence of the cutouts. When subjected to the force-applying object, the sinking degree thereof is greater than the sinking degree of the fabric in the area outside the dotted line. In this embodiment, the area enclosed by the two cutouts 121 and the two dotted lines constitutes the second flexible area 120 of the first pressure-bearing body 100, and the area enclosed by the two cutouts 121 and the two dotted lines constitutes the first flexible area 110 of the first pressure-bearing body 100.

[0086] It should be noted that the above construction method of the first pressure-bearing body 100 is only exemplary, and any method that can construct two different surface stress areas falls within the protection scope of this application.

[0087] In another method for constructing a pressure-bearing body, the pressure-bearing body includes a first pressure-bearing body 100 and a second pressure-bearing body 200. The construction method of the first pressure-bearing body 100 is detailed in the above-mentioned various construction methods, which will not be repeated here.

[0088] The second pressure-bearing body 200 contains a flowing medium. The second pressure-bearing body 200 has two structures:

[0089] 1. The second pressure-bearing body 200 has a single and undivided cavity for enclosing the flowing medium.

[0090] 2. The second pressure-bearing body 200 encloses the cavity of the flowing medium and is divided into a plurality of partitions 210, see Figure 6 Schematic diagram of the structure of the second pressure-bearing body 200.

[0091] The undivided volume in the first structural form or each partition 210 in the second structural form is defined as a pressure-bearing area.

[0092] Figure 7 FIG. 1 is a schematic diagram of a pressure-bearing body according to an embodiment of the present application. Figure 7 The second pressure-bearing body 200 is filled in an open cavity, and the entire cavity of the second pressure-bearing body 200 is a pressure-bearing area. The first pressure-bearing body 100 is arranged above the pressure-bearing area, and the first pressure-bearing body 100 can be in direct or indirect contact with the second pressure-bearing body 200.

[0093] In the area where the pressure-bearing zone is located, the first flexible area 110 of the first pressure-bearing body 100 and the second pressure-bearing body 200 in the projection area below it together constitute the inert part of the pressure-bearing body, and the second flexible area 120 and the second pressure-bearing body 200 in the projection area below it together constitute the active part of the pressure-bearing body.

[0094] The working principle of the pressure-bearing body composed of the first pressure-bearing body 100 and the second pressure-bearing body 200 is as follows: when a force-applying object acts on it, the flow medium in the second pressure-bearing body 200 migrates. The inert part supports the force-applying object through the liquid pressure transmitted to the first flexible area 110 by the flow medium in the second pressure-bearing body 200 and the surface stress of the first flexible area 110 itself, and the active part supports the force-applying object through the elastic force transmitted to the second flexible area 120 by the flow medium in the second pressure-bearing body 200 and the surface stress of the second flexible area 120 itself. Finally, the resultant force of the liquid pressure and the surface stress in the inert part is close to the resultant force of the elastic force and the surface stress in the active part, so the force-applying object obtains an indifferent support force on the surface in contact with the active part and the inert part.

[0095] Figure 8 FIG. 1 is a schematic diagram of another pressure-bearing body according to an embodiment of the present application. Figure 8 , the second pressure-bearing body 200 is filled in an open cavity, and each partition is defined as a pressure-bearing area. The first pressure-bearing body 100 is arranged above at least one pressure-bearing area, and in each pressure-bearing area where the first pressure-bearing body 100 is arranged, the first pressure-bearing body 100 can be in direct or indirect contact with the second pressure-bearing body 200. The construction method of the first pressure-bearing body 100 corresponding to each partition is the same as the above-mentioned method 1, method 2, method 3 or method 4, etc., which will not be repeated here.

[0096] It should be noted that arranging the first pressure-bearing body 100 above at least one pressure-bearing area means that the first pressure-bearing body 100 may be set above each partition of the second pressure-bearing body 200. The specific position above the partition or partitions corresponding to the first pressure-bearing body 100 can be determined or adjusted according to specific actual needs.

[0097] In each pressure-bearing zone, the first flexible region 110 of the first pressure-bearing body 100 located in the pressure-bearing zone and the second pressure-bearing body 200 in the projection area below it together constitute the inert part of the pressure-bearing body, and the second flexible region 120 and the second pressure-bearing body 200 in the projection area below it together constitute the active part of the pressure-bearing body.

[0098] In the pressure-bearing area provided with the first pressure-bearing body 100, the working principle is as follows: when the force-applying object acts on the pressure-bearing body, the flow medium in the second pressure-bearing body 200 migrates. The inert part supports the force-applying object through the liquid pressure transmitted to the first flexible area 110 by the flow medium in the second pressure-bearing body 200 and the surface stress of the first flexible area 110 itself, and the active part supports the force-applying object through the elastic force transmitted to the second flexible area 120 by the flow medium in the second pressure-bearing body 200 and the surface stress of the second flexible area 120 itself. Finally, the resultant force of the liquid pressure and the surface stress in the inert part is close to the resultant force of the elastic force and the surface stress in the active part, so the force-applying object obtains an indifferent support force on the surface in contact with the active part and the inert part.

[0099] For a pressure-bearing body with multiple pressure-bearing zones, not every pressure-bearing zone is provided with a first pressure-bearing body 100. The corresponding pressure-bearing zones of the first pressure-bearing body 100 can be allocated according to actual needs. Figure 8 .

[0100] Fig. 9 FIG. 1 is a schematic diagram of a structure of a pressure-bearing zone according to an embodiment of the present application, see Fig. 9 In the pressure-bearing area where the first pressure-bearing body 100 is provided, the number of the first pressure-bearing body 100 can be multiple. Each first pressure-bearing body 100 includes at least one first flexible area 110, and the first flexible area 110 is in a strip shape. In a pressure-bearing area, different multiple first pressure-bearing bodies 100 can be arranged at intervals in the width direction of the strip according to actual needs.

[0101] It can be seen from the above technical scheme that the adaptive pressure-bearing method in this application does not need to set a containing device such as a communicating vessel outside the pressure-bearing body, but by providing a pressure-bearing body, the pressure-bearing body has an active part and an inert part with different surface stresses. When the force-applying object acts on the pressure-bearing body, both the active part and the inert part are deformed, but the pressure-bearing surface of the active part and the pressure-bearing surface of the inert part are at different positions of depression. Finally, the surface stress of the pressure-bearing surface of the active part is close to the surface stress of the pressure-bearing surface of the inert part, and the surface of the force-applying object in contact with the pressure-bearing surface of the active part and the pressure-bearing surface of the inert part obtains an indifferent bearing force. Therefore, when this application is applied to a carrier, it can make the human body feel comfortable, save volume, and reduce production costs.

[0102] According to the second aspect of the present application, a pressure-bearing structure adopting the above-mentioned adaptive pressure-bearing method is also provided.

[0103] The pressure-bearing structure includes a pressure-bearing body, which includes an active part and an inert part. The expandable range of the active part is greater than that of the inert part. When a force-applying object acts on the pressure-bearing body, the pressure-bearing body deforms. The pressure-bearing surface of the active part and the pressure-bearing surface of the inert part support the force-applying object through differential position changes.

[0104] See also Figure 2 to Figure 5 The pressure-bearing body includes a first pressure-bearing body 100 and a pressure-bearing body 300. The pressure-bearing body 300 is provided with an open cavity. The first pressure-bearing body 100 is stretched on the open side of the cavity. The first pressure-bearing body 100 includes a first flexible region 110 and a second flexible region 120 with different surface stresses. The surface stress of the first flexible region 110 is greater than the surface stress of the second flexible region 120. The first flexible region 110 constitutes an inert portion, and the second flexible region 120 constitutes an active portion.

[0105] The arrangement of the first flexible region 110 and the second flexible region 120 can be seen in Figure 2 to Figure 5 It should be noted that, Figure 2 to Figure 5 The arrangement of the first flexible region 110 and the second flexible region 120 is only exemplary, and any arrangement that can construct two different surface stress regions falls within the protection scope of this application.

[0106] In the embodiment of the present application, the state of the first pressure-bearing body 100 is usually stretched and flattened.

[0112] It should be noted that Fig.10 , Fig.11 The purpose of this description is only to illustrate the method of supporting and pulling the first belt-shaped object and the second belt-shaped object through the support rod 400, and is not to limit the positional relationship between the first belt-shaped object and the second belt-shaped object.

[0115] It should be noted that the above-mentioned supporting and stretching structures are only exemplary, and any structure that can support, stretch and flatten a belt-like object or a flexible cloth-like object falls within the protection scope of this application.

[0116] In another embodiment of the pressure-bearing body, the pressure-bearing body includes a pressure-bearing body 300, a first pressure-bearing body 100 and a second pressure-bearing body 200. The structures of the pressure-bearing body 300 and the first pressure-bearing body 100 are described in detail. Figure 10 to Figure 13 The structures shown in the above are not described in detail here.

[0117] The second pressure-bearing body 200 contains a fluid medium which is filled in the open cavity of the pressure-bearing body 300. Figure 7 The second pressure-bearing body 200 encloses a single cavity of the flowing medium without partitions, see Figure 7 . Or the chamber is divided into multiple partitions, see Figure 8 .

[0118] The undivided cavity or each partition can be defined as a pressure zone.

[0119] In a pressure-bearing area, the first pressure-bearing body 100 may be disposed, or may not be disposed. For a pressure-bearing area where the first pressure-bearing body 100 is disposed, the first pressure-bearing body 100 is disposed above the second pressure-bearing body 200 and may be in direct or indirect contact with the second pressure-bearing body 200 .

[0120] The working principle of the pressure-bearing body including the first pressure-bearing body 100 and the second pressure-bearing body 200 is as follows: when a force-applying object acts on the pressure-bearing body, the flow medium in the second pressure-bearing body 200 migrates. The inert part supports the force-applying object through the liquid pressure transmitted to the first flexible region 110 by the flow medium in the second pressure-bearing body 200 and the surface stress of the first flexible region 110 itself, and the active part supports the force-applying object through the elastic force transmitted to the second flexible region 120 by the flow medium in the second pressure-bearing body 200 and the surface stress of the second flexible region 120 itself. Finally, the resultant force of the liquid pressure and the surface stress in the inert part is close to the resultant force of the elastic force and the surface stress in the active part, so the force-applying object obtains an indifferent support force on the surface in contact with the active part and the inert part.

[0121] For the layout position and layout method of the first pressure zone, please refer to Figure 8 and Fig. 9 , I will not go into details here.

[0122] According to a third aspect of the present application, a bedding is also provided, wherein the bedding comprises a cushion body, and the pressure-bearing structure in the above structure constitutes part or all of the cushion body.

[0124] The working principle of the pressure-bearing structure will be further described below by referring to the working principle of the pressure-bearing structure when the user uses the cushion body including the pressure-bearing structure.

[0125] Fig.15 This is a diagram of the deformation state of the pressure-bearing structure when the user acts on the pressure-bearing structure. Fig.15 , take the waist and hip area of ​​the human body as an example:

[0126] Case 1: The part corresponding to line segments 1 and 3 is the inert part of the pressure-bearing structure. The part corresponding to line segments 2 and 4 is the active part of the pressure-bearing structure.

[0127] The surface stress of the parts corresponding to line segments 2 and 4 is small, and the compressed parts are easy to sink to accommodate the shoulders and hips. The uncompressed parts in line segments 2 and 4 are greatly lifted, and the parts corresponding to line segments 1 and 3 are slightly lifted. The liquid level difference of the flowing medium generates a supporting force to support the neck and waist.

[0128] Case 2: The part corresponding to line segments 1 and 3 is the active part of the pressure-bearing structure. The part corresponding to line segments 2 and 4 is the inert part of the pressure-bearing structure.

[0129] The parts corresponding to line segments 2 and 4 have large surface stress, the corresponding parts are under pressure, and the whole body sinks; the parts corresponding to line segments 1 and 3 are greatly lifted up, tightly fitting the neck and waist, and the user gets an indistinguishable sense of touch at the parts in contact with the pressure-bearing structure.
