[0002] With economic and technological development and improved living standards, the comfort of daily necessities, especially bedding, is constantly improving. Mattresses, as the primary bedding item, are a strong guarantee for high-quality sleep. Ordinary mattresses have poor conformation, offer few points of support for the body, and leave many unsupported areas, preventing the muscles from fully relaxing and affecting sleep quality. Summary of the Invention

[0003] This application provides a support device to improve the support effect on the buttocks and waist of the human body.

[0004] This application provides a carrier, including:

[0005] A matrix, wherein a tough core is disposed within the matrix, and both the matrix and the tough core are filled with fluid;

[0006] The height variation range of the resilient core is smaller than that of the matrix, and the resilient core is configured to be at least opposite to the waist and hips of the human body.

[0007] In some possible implementations, at least one connector is provided between the top and bottom surfaces of the resilient core;

[0008] The at least one connector divides the tough core into a plurality of semi-enclosed pillars, with two adjacent semi-enclosed pillars sharing one connector. The connector is used to limit the maximum distance between the top surface and the bottom surface of each semi-enclosed pillar of the tough core.

[0009] In some possible implementations, the at least one connector includes at least one short connector;

[0010] The height of at least one short connector is less than one-quarter of the cross-sectional perimeter of the semi-enclosed column in which the short connector is located.

[0011] In some possible implementations, the length of the top surface of the semi-enclosed column where the short connector is located on the cross-section is greater than one-quarter of the perimeter of the cross-section;

[0012] After the resilient core is filled with fluid, the top surfaces of the two adjacent semi-enclosed columns where the short connector is located bend at the connection point with the short connector, forming a pressure-adaptive concave groove.

[0013] The pressure-adaptive grooves extend along the width of the resilient core and are designed to unfold under pressure on the buttocks of the human body to conform to the curve of the buttocks.

[0014] In some possible implementations, the connector has at least two members, and the at least two connectors further include a high connector located on one side of the low connector;

[0015] The height of the high connector is greater than or equal to one-quarter of the cross-sectional perimeter of the semi-enclosed column where the high connector is located.

[0016] In some possible implementations, the maximum distance from the top surface to the bottom surface of the semi-enclosed column where the high connector is located is the same as the maximum distance from the top surface to the bottom surface of the semi-enclosed column where the low connector is located.

[0017] In some possible implementations, the carrier further includes:

[0018] A pillow module is disposed within the substrate or on one side of the substrate, and the pillow module is configured to face the head and neck of the human body.

[0019] In some possible implementations, the support device further includes edge guards;

[0020] The edge guard is disposed at the edge of the substrate and at least partially surrounds the substrate; or,

[0021] The edge guard is disposed inside the substrate and located on at least one of the two opposite sides of the tough core along the width direction of the substrate.

[0022] In some possible implementations, when the edge protector is disposed at the edge of the substrate, the pillow module is integrated with the edge protector; when the edge protector is disposed inside the substrate, the tough core is also connected to the edge protector; and / or,

[0023] The pillow module is spaced apart from the resilient core.

[0024] In some possible implementations, at least one of the tough cores is disposed within the matrix;

[0025] When two tough cores are provided in the matrix, the two tough cores are arranged side by side along the width direction of the matrix.

[0026] The load-bearing device provided in this application includes a base body with a resilient core disposed within it. Both the base body and the resilient core are filled with fluid. The height variation range of the resilient core is smaller than that of the base body, and the resilient core is configured to be at least opposite to the waist and hips of the human body. The resilient core has higher overall stiffness and is less prone to deformation, thus providing reliable support for the waist and hips of the human body. Attached Figure Description

[0054] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0055] In the load-bearing device provided in this application embodiment, a resilient core is provided within the matrix, and both the matrix and the resilient core are filled with fluid; the height variation range of the resilient core is smaller than that of the matrix. The resilient core has higher overall stiffness, is less prone to deformation, and is positioned opposite the waist and hips of the human body, thus providing reliable support for the waist and hips.

[0056] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0057] See Figures 1 to 17 This application provides a support device, such as a mattress, which can be a single mattress or a double mattress. The support device includes a base 10, within which a resilient core 20 is disposed. Both the base 10 and the resilient core 20 are filled with fluid. The height variation range of the resilient core 20 is smaller than that of the base 10, and the resilient core 20 is configured to be at least opposite to the waist and hips of the human body.

[0058] The matrix 10 is hollow, with a first accommodating space for housing the tough core 20 and the fluid. The matrix 10 is made of materials including polyvinyl chloride (PVC), thermoplastic polyurethanes (TPU), and rubber. The matrix 10 is equipped with corresponding inlets, such as... Figure 2 As shown in F1, the inlet is connected to the first accommodating space to allow fluid to enter or flow out. The inlet can also be sealed to keep the substrate 10 in a certain shape.

[0059] The tough core 20 can deform under external force without fracturing, thus providing load-bearing capacity. The tough core 20 is disposed within the substrate 10 and can be fixedly connected to it. For example, the tough core 20 is disposed within a first receiving space and fixed relative to the top wall, side wall, or bottom wall of the first receiving space. The tough core 20 is hollow internally, forming a second receiving space for containing fluid. The tough core 20 is made of materials including polyvinyl chloride, polyether-type polyurethane thermoplastic elastomers, rubber, etc. The material of the tough core 20 can be the same as or different from that of the substrate 10; the fluid within the tough core 20 can be the same as or different from the fluid within the substrate 10.

[0060] In some possible examples, the resilient kernel 20 is configured with corresponding imports, such as Figure 2 As shown in F2. This inlet communicates with the second accommodating space to allow fluid to enter or exit. The inlet can also be sealed to maintain the shape of the tough core 20. For example, the inlet of the tough core 20 extends to and connects with the substrate 10, thereby fixing the tough core 20 relative to the substrate 10. In this way, the tough core 20 is connected to a fixed position on the substrate 10, and there is essentially no relative movement between the tough core 20 and the substrate 10.

[0061] In some possible examples, the fluid can be an incompressible fluid, meaning the fluid density is constant and its volume is incompressible, so that its internal pressure can better balance the pressure on the human body. For example, the fluid within the matrix 10 can be water, which offers good safety. In other examples, since air can be considered an incompressible fluid at low speeds (Mach number not exceeding 0.3), the fluid within the matrix 10 can also be air.

[0062] Continue reading Figure 1 Along the length of the support device, the size of the base 10 is larger than the size of the resilient core 20. At least one end of the resilient core 20 is spaced from the corresponding end of the base 10, allowing the resilient core 20 to support the waist and hips of the human body. Along the height of the support device, the size of the base 10 is greater than or equal to the size of the resilient core 20. The size of the base 10 and the resilient core 20 are the same or very similar to ensure the resilient core 20 can bear the load. The length of the support device is also the length of the base 10, and it aligns with the direction from the head to the legs when the human body lies on the support device. The human body, from top to bottom, includes the head and neck, shoulders and back, waist, hips, and legs.

[0063] like Figure 1 As shown, the left end of the substrate 10 is spaced apart from the left end of the toughening core 20, and the right end of the substrate 10 is spaced apart from the right end of the toughening core 20. The position of the toughening core 20 within the substrate 10 can be adjusted; for example, the distance between the left end of the toughening core 20 and the left end of the substrate 10 can be adjusted as needed to accommodate different human bodies. Figure 10 As shown, the distance between the left end of the resilient core 20 and the left end of the substrate 10 is shortened, making the support device suitable for infants, toddlers, and young children.

[0064] Understandably, the shapes of the matrix 10 and the tough core 20 are determined by their internal support. When not filled with fluid, the matrix 10 and the tough core 20 are soft, deformable shells with variable shapes, capable of being folded and rolled up. After being filled with a certain amount of fluid, the matrix 10 takes on the shape of a supporting device; when fully filled with fluid, the tough core 20 forms a support with specific shape, function, and structural rigidity, its shape determined by the internal fluid pressure and its own structure, and the tough core 20 is in a tensioned state. For example, the tough core 20 may be a cuboid or cube in shape.

[0065] It is also understandable that when a person lies down (e.g., on their side) on the support device, the top surfaces of the matrix 10 and the resilient core 20 are subjected to external pressure. This external pressure is transmitted to the fluid, generating internal pressure to balance the external pressure and support the person. Under the combined action of external and internal pressure, the fluid within the matrix 10 and the resilient core 20 migrates. The area of ​​the matrix 10 corresponding to the person's shoulder forms a depression because some of the fluid within it migrates to the unpressurized area under the pressure of the person's shoulder. Consequently, the person's shoulder sinks, bringing the spine and head and neck to the same level, eliminating the need for a pillow. The area of ​​the resilient core 20 corresponding to the person's buttocks forms a depression because some of the fluid migrates directionally to the lumbar region under the pressure of the buttocks. Consequently, the person's buttocks sink, and the lumbar region is slightly raised and its resilience is enhanced, improving the lumbar support. Furthermore, the resilient core 20 with pressure-adaptive concave 21 expands under the pressure of the human buttocks, eliminating the surface tension of the resilient core 20 from hindering the sinking of the human buttocks, making the buttocks sink more easily and to a greater extent. Correspondingly, the resilience of the waist area is further enhanced, further improving the waist support.

[0066] Continue reading Figure 1 The height variation range of the resilient core 20 is smaller than that of the base 10, and the resilient core 20 is configured to be at least opposite the waist and hips of the human body. This results in higher overall stiffness of the resilient core 20, making it less prone to deformation and providing reliable support for the waist and hips. The aforementioned height variation range refers both to the maximum height range of the base 10 and the resilient core 20 from 0 to when filled with fluid, and to the height variation range of the load-bearing device after it supports the human body; that is, when the load-bearing device is in use, the height variation value of the resilient core 20 is no greater than the height variation value of the base 10.

[0067] When not supporting a human body, the height range of the tough core 20 and the substrate 10 can be 3cm-22cm, for example, 5cm-15cm, providing good support. The height of the tough core 20 is basically the same as the height of the substrate 10, or the height of the tough core 20 is slightly smaller than the height of the substrate 10, for example, the height difference is less than or equal to 1cm.

[0068] Along the length of the supporting device, a portion of the substrate 10 is directly opposite the tough core 20. This portion of the substrate 10 is influenced by the tough core 20, and its height variation range is basically consistent with that of the tough core 20. Another portion of the substrate 10 is offset from the tough core 20, located on both sides of the tough core 20. This portion of the substrate 10 has greater flexibility, and its height variation range is greater than that of the tough core 20.

[0069] The resilient core 20 is positioned at least opposite the waist and hips of the human body, thus supporting at least the waist and hips. For example, the resilient core 20 is positioned opposite the waist and hips of the human body. Another example is that the resilient core 20 is positioned opposite the waist, hips, and part of the legs. Yet another example is that the resilient core 20 is positioned opposite the waist, hips, and part of the back.

[0070] To better support the human body, the top surface of the resilient core 20 has pressure-adaptive grooves 21, which are at least opposite to the buttocks. The extension direction of these pressure-adaptive grooves 21 is substantially consistent with the width direction of the base 10 (which is also the width direction of the supporting device), and the extension direction of the pressure-adaptive grooves 21 is within a reasonable error range, for example, 5°. The pressure-adaptive grooves 21 ensure the necessary extension of the top surface of the resilient core 20 when fitting the curve of the buttocks. See also... Figure 3 When the buttocks ( Figure 3 (As shown at point B) When the pressure-adaptive groove 21 is located in the area, it expands, making it easier for the buttocks to sink.

[0071] In some possible examples, such as Figures 4 to 7 As shown, the pressure-adaptive groove 21 is located at one end of the top surface of the resilient core 20, providing support for the buttocks of the human body. In other possible examples, such as Figure 8 As shown, the pressure-adaptive grooves 21 can also be distributed across the entire top surface of the tough core 20, providing support for the hips and waist of the human body.

[0072] In the two examples above, the pressure-adaptive grooves 21 can have one or more grooves. When there are multiple pressure-adaptive grooves 21, they are arranged along the length of the load-bearing device. Each pressure-adaptive groove 21 has a semi-enclosed post on each side. The pressure-adaptive grooves 21 are spaced apart to ensure that the maximum distance between the bottom and top surfaces of each semi-enclosed post is the same.

[0073] Understandably, the more pressure-adaptive grooves 21 there are, the wider the range of human heights they can accommodate. A greater number of pressure-adaptive grooves 21 also means a wider distribution along the length of the support structure, thus allowing for a greater range of hip movement and accommodating a wider range of human heights. For example... Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the number of pressure-adaptive grooves 21 are one, two, three, four, and five, respectively. Among them, the load-bearing device with five pressure-adaptive grooves 21 can be adapted to all height ranges of infants, toddlers, children, teenagers, and adults.

[0074] See Figure 3 The tough core 20 has two pressure-adaptive grooves 21, which are the first groove and the second groove, respectively. For people of different heights from low to high, the high point of the buttocks can be located on the side of the first groove away from the second groove, the first groove, between the first groove and the second groove, the second groove, and the side of the second groove away from the first groove, respectively.

[0075] It is also understandable that the number of pressure-adaptive grooves 21 can be matched with the length, position, etc. of the tough core 20 to suit different groups of people.

[0076] For example, such as Figure 4 and Figure 7 As shown, the tough core 20 has the same length and position, and the number of pressure-adaptive grooves 21 is one and four, respectively. A load-bearing device with one pressure-adaptive groove 21 can be used for adults, while a load-bearing device with four pressure-adaptive grooves 21 can be used for teenagers and adults.

[0077] For example, such as Figure 5 and Figure 9 As shown, the length and position of the resilient core 20 vary, but the number of pressure-adaptive grooves 21 is always two. A support device with a shorter resilient core 20 and a smaller distance from one end of the substrate 10 can be fitted to infants, toddlers, and young children. A support device with a longer resilient core 20 and a larger distance from one end of the substrate 10 can be fitted to adults.

[0078] Continue reading Figures 1 to 10 At least one connector 30 is provided between the top and bottom surfaces of the tough core 20; the at least one connector 30 divides the tough core 20 into multiple semi-closed pillars, and two adjacent semi-closed pillars share one connector 30. The connector 30 is used to limit the maximum distance between the top and bottom surfaces of each semi-closed pillar of the tough core 20.

[0079] The connector 30 is located inside the tough core 20, with one end connected to the top surface of the tough core 20 and the other end connected to the bottom surface of the tough core 20. The connector 30 can be made of the same sheet as the tough core 20, and its two ends are fused and fixed to the top and bottom surfaces of the tough core 20, respectively. The extension direction of the connector 30 is either consistent with or perpendicular to the width direction of the base 10.

[0080] One or more connectors 30 may be provided, which divide the tough core 20 into at least two semi-enclosed pillars, with adjacent semi-enclosed pillars sharing one connector 30. For example... Figures 4 to 8As shown, five connectors 30 are provided, dividing the tough core 20 into six semi-enclosed pillars. Each semi-enclosed pillar is formed by a portion of the surface of the tough core 20 and the connector 30. For example, the semi-enclosed pillars at both ends are formed by a portion of the top surface, a portion of the bottom surface, the corresponding side surface of the tough core 20, and a connector 30. The other semi-enclosed pillars are formed by a portion of the top surface, a portion of the bottom surface of the tough core 20, and two connectors 30.

[0081] In some possible implementations, at least one connector 30 includes at least one low connector 32, meaning that connector 30 may be partially or entirely composed of low connectors 32. The height of at least one low connector 32 is less than one-quarter of the cross-sectional perimeter of the semi-enclosed column to which the low connector 32 is located. The low connector 32 reduces the distance between the top and bottom surfaces of the tough core 20 at the connection point, thereby facilitating the formation of corresponding pressure-adaptive grooves 21 on the top surface of the tough core 20.

[0082] The semi-enclosed columns containing the aforementioned short connector 32 are the two semi-enclosed columns on both sides of the short connector 32; the term "perpendicular to the short connector 32" refers to being perpendicular to the extension direction of the short connector 32, that is, taking the plane perpendicular to the extension direction of the short connector 32 as the cross-section. The perimeter of the cross-section of the semi-enclosed column perpendicular to the short connector 32 includes the sum of the cross-sectional length of the corresponding tough core 20 and the height of the connector 30.

[0083] by Figure 5 Taking the structure shown as an example, there are five connectors 30, six semi-enclosed bodies, and three short connectors 32. The semi-enclosed body containing the rightmost short connector 32 includes the rightmost semi-enclosed body and the next rightmost semi-enclosed body. The perimeter of the cross-section corresponding to the rightmost semi-enclosed body is the sum of the height of the rightmost short connector 32 and the cross-sectional lengths of part of the top surface, part of the bottom surface, and the right side surface of the tough core 20. The perimeter of the cross-section corresponding to the next rightmost semi-enclosed body is the sum of the heights of the rightmost short connector 32 and the next rightmost short connector 32, and the cross-sectional lengths of part of the top surface and part of the bottom surface of the tough core 20.

[0084] In some possible examples, the top surface of the semi-enclosed column where the short connector 32 is located has a cross-sectional length greater than one-quarter of the cross-sectional perimeter; after the tough core 20 is filled with fluid, the top surfaces of the two adjacent semi-enclosed columns where the short connector 32 is located bend at the connection point with the short connector 32 to form a pressure-adaptive groove 21; the pressure-adaptive groove 21 extends along the width direction of the tough core 20 and is used to unfold under the pressure of the human buttocks, eliminating the resistance of the surface tension of the tough core 20 to the sinking of the human buttocks, making the buttocks sink more easily.

[0085] In this configuration, the height of the short connector 32 is less than one-quarter of the cross-sectional perimeter of the semi-enclosed column to which it is located, and the length of the top surface of the semi-enclosed column to which the short connector 32 is located is greater than one-quarter of the cross-sectional perimeter. Thus, after the tough core 20 is filled with fluid, the top surface of the tough core 20 bends at the connection point with the short connector 32, forming a pressure-adaptive groove 21 between adjacent semi-enclosed columns, and reducing the distance between the short connector 32 and the adjacent connector 30.

[0086] It is understandable that, such as Figures 3 to 9 As shown, the bottom surface of the tough core 20 can also be correspondingly formed with pressure-adaptive grooves 21, which do not require load-bearing capacity. For example, after the tough core 20, manufactured using PVC technology, is filled with fluid, the bottom surfaces of the two adjacent semi-enclosed columns containing the short connector 32 bend at the connection point, forming pressure-adaptive grooves 21. In other possible examples, such as... Figure 10 As shown, the tough core 20 has pressure-adaptive grooves 21 only on its top surface. The depth of the pressure-adaptive grooves 21 can be further increased to accommodate situations where deeper grooves are required.

[0087] In some possible examples, there are at least two connectors 30, and the at least two connectors 30 also include a high connector 31 located on one side of the low connector 32; the height of the high connector is greater than the height of the low connector, and further, the height of the high connector 31 is greater than or equal to one-quarter of the cross-sectional perimeter of the semi-enclosed column in which the high connector 31 is located. In this way, the high connector 31 can avoid excessive height differences between the parts of the tough core 20, and at the same time, there is no need to form a corresponding pressure-adaptive groove 21.

[0088] The maximum distance between the top and bottom surfaces of the semi-enclosed column where the high connector 31 is located is the same as the maximum distance between the top and bottom surfaces of the semi-enclosed column where the low connector 32 is located. This ensures that no pressure-adaptive groove 21 is formed at the connection between the high connector 31 and the tough core 20. In other words, the top surface of the semi-enclosed body where the high connector 31 is located has a smooth transition, guaranteeing the length of the smooth portion of the tough core 20, allowing this portion of the tough core 20 to bear the load evenly.

[0089] See Figure 1 , Figure 11 and Figure 12 The support device also includes a pillow module 40, which is disposed within the base 10 or on one side of the base 10. The pillow module 40 is configured to face the head and neck of the human body to support the head and neck. The pillow module 40 can be at the same height as the base 10, i.e., flush with the base 10, or it can protrude from the base 10. The pillow module 40 and the resilient core 20 can be spaced apart.

[0090] In some possible examples, such as Figure 1 and Figure 12 As shown, the pillow module 40 is disposed within the base 10, i.e., the pillow module 40 is built-in. The pillow module 40 and the resilient core 20 can be arranged at intervals along the length of the load-bearing device. The spacing between the pillow module 40 and the resilient core 20 can accommodate people of different heights.

[0091] In other possible examples, such as Figure 11 As shown, the pillow module 40 is disposed outside the base 10, that is, the pillow module 40 is external. The pillow module 40 and the base 10 are separately disposed, and the pillow module 40 can be disposed on either side of the base 10 as needed, so as to cooperate with the resilient core 20 to further perform segmented and continuous adaptation to people of different heights.

[0092] The pillow module 40 can be implemented in various ways. For example, the pillow module 40 can be soft and enclosed, filled with fluid, and have an inlet, such as... Figure 11 and Figure 12 As shown in F3. The pillow module 40 is made of materials including polyvinyl chloride, polyether-type polyurethane thermoplastic elastomers, rubber, etc., and the fluid inside the pillow module 40 is water or air. Alternatively, the pillow module 40 may be made of high-resilience sponge, rigid sponge, gel memory foam, etc.

[0093] See Figures 13 to 15 The support device also includes a guard edge 50, which is disposed at the edge of the substrate 10 and at least partially surrounds the substrate 10; or, the guard edge 50 is disposed inside the substrate 10 and located on at least one of the two opposite sides of the tough core 20 along the width direction of the substrate 10. The guard edge 50 can provide support for the edge of the substrate 10, prevent the edge of the substrate 10 from collapsing, and improve the stability of the substrate 10.

[0094] In some possible examples, such as Figure 13 As shown, the edge guard 50 is disposed at the edge of the substrate 10, that is, the edge guard 50 is located outside the substrate 10. The edge guard 50 may partially surround the substrate 10 or completely surround the substrate 10. For example, as shown... Figure 3 As shown, the edge guard 50 surrounds the base 10 for a full circumference, forming a four-sided guard, which can provide comprehensive edge support and improve stability.

[0095] For example, such as Figure 14As shown, the edge protector 50 can be integrated with the pillow module 40, meaning the edge protector 50 and the pillow module 40 form a single unit, and part of the protector can be used as the pillow module 40, reducing loosening. For example, both the edge protector 50 and the pillow module 40 are closed bodies filled with fluid. Alternatively, the edge protector 50 and the pillow module 40 can be separate, with the pillow module 40 embedded within the edge protector 50. For example, the edge protector 50 and the pillow module 40 are closed bodies filled with fluid; or, for example, the pillow module 40 is high-resilience sponge.

[0096] In other possible examples, such as Figure 15 As shown, the edge guard 50 is disposed inside the substrate 10 and located on opposite sides of the toughening core 20 along the width direction of the substrate 10. The edge guard 50 can also be connected to the toughening core 20 to improve stability. For example, the edge guard 50 is a closed body filled with fluid, that is, the edge guard 50 is connected to the toughening core 20 but not in communication with it.

[0097] See Figure 16 and Figure 17 The substrate 10 contains at least one resilient core 20; when two resilient cores 20 are provided within the substrate 10, they are arranged side-by-side along the width of the substrate 10. This allows the load-bearing device to support two people separately, and each resilient core 20 can be customized according to individual needs to improve the flexibility and adaptability of the load-bearing system. The two resilient cores 20 can share a single pillow module 40, or each can have its own dedicated pillow module 40.

[0098] The support device provided in this embodiment includes a base 10, within which a resilient core 20 is disposed. Both the base 10 and the resilient core 20 are filled with fluid. The height variation range of the resilient core 20 is smaller than that of the base 10, and the resilient core 20 is configured to be at least opposite to the waist and hips of the human body. The resilient core 20 has higher overall stiffness and is less prone to deformation, thus providing reliable support for the waist and hips of the human body.
