Description

Technical Field

[0001] This utility model relates to the field of mattress technology, and in particular to a mattress and bed that prevents back compression. Background Technology

[0002] As people increasingly pursue healthy and comfortable sleep, smart mattresses and electric beds with posture adjustment functions have become popular products on the market. These products typically use built-in drive mechanisms to raise and lower different areas of the bed to adapt to the user's posture needs in different scenarios such as resting, reading, and watching movies.

[0003] However, adjustable mattresses currently on the market still have some issues in actual use, which can affect the user experience. Specifically, when adjusting the back posture, users often feel their body being compressed, and this discomfort disrupts the smoothness and comfort of the adjustment process.

[0004] Therefore, how to provide a mattress that can eliminate the feeling of pressure during dynamic adjustment is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The main purpose of this utility model is to provide a mattress and bed that prevents back compression, so as to solve the above-mentioned technical problems.

[0006] In a first aspect, this utility model provides a mattress that prevents back compression, comprising: A support frame, the support frame including a back frame and a seat frame that can rotate relative to each other; A drive mechanism, including a back drive mechanism connected to the back frame, for driving the back frame to rotate relative to the seat frame; The back frame includes at least two support beams extending along their length, and an elastic element arranged laterally between the support beams. The elastic element forms a flexible support surface for supporting the user's back. The flexible support surface is configured to elastically deform in response to the pressure on the user's back during the process of the back drive mechanism driving the back frame to rotate and rise, so as to adapt to the user's back contour and buffer the pressure.

[0007] The elastic element is an S-shaped spring.

[0008] The back frame includes two longitudinally extending support beams spaced apart along its width, and the two ends of the S-shaped spring are respectively fixed to the corresponding support beams.

[0009] The back frame includes four longitudinally extending support beams spaced apart along its width; multiple S-shaped springs are provided and are respectively disposed between two support beams on each side along the width direction.

[0010] The S-shaped spring has hook-shaped portions at both ends, and the support beam has hook portions that cooperate with the hook-shaped portions. The hook-shaped portions are hooked onto the corresponding hook portions.

[0011] The support frame further includes a head frame, which is rotatably connected to the back frame; the drive mechanism further includes a head drive mechanism, which is connected to the head frame and is used to drive the head frame to rotate relative to the back frame.

[0012] The support frame further includes a leg frame, which is rotatably connected to the seat frame; the drive mechanism further includes a leg drive mechanism, which drives the leg frame to rotate relative to the seat frame.

[0013] The seat frame includes a first seat and a second seat that can be folded relative to each other; the back frame is rotatably connected to the first seat, and the leg frame is rotatably connected to the second seat.

[0014] The support frame is topped with a mattress body, which includes at least one elastic layer.

[0015] It also includes a base frame, and the seat frame is detachably connected to the top of the base frame.

[0016] The bottom of the base frame is provided with multiple bed legs.

[0017] Secondly, this utility model also provides a bed, including the mattress as described in the first aspect.

[0018] The beneficial technical effects of this utility model are as follows: The anti-pressure back mattress provided by this utility model has a flexible support surface in the back frame, which is composed of support beams and horizontally arranged elastic elements.

[0026] Please also refer to Figures 1-6 This utility model provides a mattress 50 designed to prevent back compression. The mattress 50 aims to address the problem in existing adjustable mattresses where the user's body is easily compressed during backrest elevation, leading to decreased comfort. The mattress 50 includes a support frame comprising a backrest frame 11 and a seat frame 12 that are rotatable relative to each other; and a drive mechanism including a backrest drive mechanism 21 connected to the backrest frame 11 for driving the backrest frame 11 to rotate relative to the seat frame 12. The backrest frame 11 includes at least two support beams 111 extending along its length, and elastic elements 112 laterally disposed between the support beams 111. The elastic elements 112 form a flexible support surface for supporting the user's back. This flexible support surface is configured to elastically deform in response to pressure from the user's back during the backrest drive mechanism 21's rotation and elevation of the backrest frame 11, adapting to the user's back contour and cushioning the pressure. The mattress 50 provided in this embodiment provides a flexible support surface composed of elastic elements 112 in the back frame 11, which allows the mattress 50 to better conform to and adapt to the user's body contour during dynamic adjustment, thereby effectively eliminating the feeling of pressure and improving the user experience.

[0027] In this embodiment, the mattress includes a support frame and a drive mechanism.

[0028] The support frame is the skeleton of the mattress, providing primary support for the user's body. This support frame includes a back frame 11 and a seat frame 12. The back frame 11 supports the user's back area, and the seat frame 12 supports the user's buttocks and nearby thigh area. The back frame 11 and the seat frame 12 are connected by hinges or other means to allow relative rotation, enabling the back frame 11 to rotate about the connection point as an axis, thereby allowing adjustment of the user's upper body posture.

[0029] The drive mechanism provides power for adjusting the posture of the support frame. The drive mechanism includes a back drive mechanism 21. This back drive mechanism 21 can be an electric actuator, a combination of a motor and linkage, or other drive devices well known to those skilled in the art. The back drive mechanism 21 is connected to the back frame 11; for example, its output end (or lifting end) can be hinged to a force point on the side of the back frame 11 away from the seat frame 12, and its input end (or fixed end) is connected to a fixed part of the mattress, such as the seat frame 12. By activating the back drive mechanism 21, the back frame 11 can be driven to rotate relative to the seat frame 12, thereby raising or lowering the backrest.

[0030] The key to this embodiment lies in the support structure of the back frame 11 itself. Unlike traditional structures that use a single rigid wooden or metal plate laid on the frame as a support surface, the back frame 11 in this embodiment includes at least two support beams 111 and multiple elastic elements 112 arranged laterally therebetween. These elastic elements 112 together constitute a flexible support surface. This flexible support surface is configured such that, during the process of the back drive mechanism 21 driving the back frame 11 to rotate and rise from a lying position, when the user's back and buttocks area experience displacement and pressure concentration due to posture changes, the elastic elements 112 constituting the flexible support surface can undergo corresponding elastic deformation in response to the pressure of the user's body (specifically, the back).

[0031] This elastic deformation serves two main purposes: firstly, it actively adapts to changes in the user's body contours, forming a more conforming support surface and avoiding rigid contact caused by a mismatch between the mattress surface and the body's shape; secondly, it effectively cushions and disperses localized pressure exerted by the user's body, redistributing concentrated pressure over a wider area. Through this adaptive deformation and pressure cushioning, the squeezing sensation on the user's body during mattress backrest adjustment is significantly reduced, making the entire adjustment process smoother, more natural, and more comfortable.

[0032] In this embodiment, the elastic element 112 can be composed of multiple S-shaped springs arranged side by side, an elastic mesh structure, or a flexible sheet, etc. As long as it can produce the expected elastic deformation when subjected to the pressure of the user's body, the purpose of this embodiment can be achieved.

[0033] In one embodiment, the elastic element 112 is an S-shaped spring.

[0034] In this embodiment, the elastic element 112 is specifically an S-shaped spring. An S-shaped spring is a metal elastic element 112 with a continuous "S"-shaped bending structure. Compared with a complete flexible plate or other elastic structures, the S-shaped spring can generate a larger range of elastic deformation through its own bending structure when subjected to external force, and has good resilience, is not prone to permanent deformation, and has a longer service life.

[0035] In practice, when the back frame 11 is raised and the user's body (back) applies pressure to the mattress surface, this pressure acts directly on the S-shaped springs on the back frame 11. The S-shaped springs then undergo downward elastic bending deformation, forming a concave arc surface to accommodate and conform to the user's body contours. This deformation actively provides buffer space for the user's body displacement and disperses the concentrated pressure, thereby effectively eliminating the squeezing sensation and discomfort caused by the rigid support surface, achieving a soft and smooth support transition.

[0036] In this embodiment, "lateral arrangement" means that the S-shaped springs extend primarily along the width of the back frame 11 (i.e., from the left to the right side of the mattress), rather than longitudinally along the length (from head to feet). This arrangement allows a smaller number of S-shaped springs to cover the width of the back frame 11, providing uniform lateral support. Specifically, the S-shaped springs can be laid laterally on the inner side of the back frame 11 in single or multiple forms, close to the user's body, so that they directly participate in forming the support surface for the user's back when the back frame 11 is raised.

[0037] With this lateral arrangement, a single or a small number of S-shaped springs can form at least part of the support surface for the user's back. This support surface is not a rigid plane, but a flexible surface formed by the elastic structure of the S-shaped springs. During the raising of the back frame 11, when pressure is applied to the user's back, these lateral S-shaped springs can undergo independent or coordinated elastic deformation, for example, producing greater downward bending in areas of higher local pressure, thereby dynamically adjusting the shape of the support surface to better conform to the curve of the user's back. Simultaneously, this lateral arrangement helps to distribute pressure evenly along the width direction, further enhancing the cushioning effect and preventing the generation of localized pressure sensations.

[0038] In other embodiments, "lateral arrangement" can be understood as the S-shaped spring being arranged within the support plane formed by the back frame 11, as opposed to a "vertical" arrangement perpendicular to the support plane. Therefore, the extension direction of the S-shaped spring can also be arranged primarily along the length direction of the back frame 11 (i.e., from the head towards the seat), and this arrangement can also form a flexible support surface in the back area.

[0039] In one embodiment, the back frame 11 includes two longitudinally extending support beams 111 spaced apart along its width, and the two ends of the S-shaped spring are respectively fixed to the corresponding support beams 111.

[0040] In this embodiment, the support beam 111 is a major structural component of the back frame 11 and is made of metal profiles, such as steel pipes. To achieve the lateral arrangement of the S-shaped springs, the back frame 11 includes two support beams 111 extending along its length (i.e., from the head to the feet), and these two support beams 111 maintain a certain distance between them. These two support beams 111 can be located on the left and right sides of the back frame 11, serving as the frame's border structure.

[0041] The S-shaped spring is horizontally positioned between the two support beams 111, with one end fixed to one support beam 111 and the other end fixed to the opposite support beam 111. In this way, the S-shaped spring is installed inside the backrest frame 11, forming an elastic support structure spanning the two support beams 111. When the user lies on the mattress, the user's back weight is transferred to the support beams 111 through these S-shaped springs, and then from the support beams 111 to the entire support frame.

[0042] This structural design is simple yet robust, ensuring that the S-spring can stably perform its elastic support function and making installation and replacement of the S-spring relatively easy. Furthermore, by adjusting the distance between the support beams 111 and the preload of the S-spring, the overall elasticity and support characteristics of the elastic element 112 can be designed and optimized to meet the comfort needs of different users.

[0043] In one embodiment, the back frame 11 includes four longitudinally extending support beams 111 spaced apart along its width direction; multiple S-shaped springs are provided and respectively disposed between two support beams 111 on each side along the width direction.

[0044] In this embodiment, the four support beams 111 extend longitudinally along the length direction of the back frame 11 (i.e., from the head to the feet) and are spaced apart along the width direction of the back frame 11 (i.e., from the left to the right). These support beams 111 are, from left to right, the first support beam 111, the second support beam 111, the third support beam 111, and the fourth support beam 111. The first and second support beams 111 form a pair on the left, and the third and fourth support beams 111 form a pair on the right. This configuration of four support beams 111 provides a zoned fixing base for the installation of the S-shaped spring.

[0045] Accordingly, multiple S-shaped springs are provided and divided into two groups. Each group of S-shaped springs is arranged laterally and fixed between corresponding pairs of support beams 111. Specifically, some S-shaped springs are arranged between the two support beams 111 on the left (e.g., the first support beam 111 and the second support beam), and other S-shaped springs are arranged between the two support beams 111 on the right (e.g., the third support beam 111 and the fourth support beam). This arrangement of left and right regions divides the support surface of the back frame 11 into two independent elastic support areas on the left and right sides, thereby providing independent elastic support and pressure buffering for two or more users using the equipment simultaneously, reducing mutual interference.

[0046] In practical use, this design with separate left and right side sections ensures that when two users are lying down, each user is primarily supported by the S-shaped spring groups in their respective areas. When the back frame 11 is raised, the pressure on the backs of the two users is applied to the S-shaped spring groups on the left and right sides respectively. Because the S-shaped spring groups on the left and right sides are independently designed, they can independently respond to the pressure of the user's body and undergo elastic deformation, thus providing personalized adaptive support for each user, reducing mutual interference caused by differences in weight, and improving comfort and stability in multi-user scenarios.

[0047] In one embodiment, the S-shaped spring is provided with hook-shaped portions 1121 at both ends, and the support beam 111 is provided with hook portions 1122 that cooperate with the hook-shaped portions 1121, and the hook-shaped portions 1121 are hooked onto the corresponding hook portions 1122.

[0048] In this embodiment, the two ends of the S-shaped spring are bent to form inward or outward hook-shaped portions 1121. These hook-shaped portions 1121 can be simple hook structures, ring structures, or other forms that facilitate hooking. Correspondingly, each support beam 111 is provided with a hook portion 1122. The hook portion 1122 can be a protruding hook, hole, groove, or a metal piece fixed to the surface of the support beam 111, and its shape and size match the hook-shaped portion 1121 to achieve a reliable mating connection.

[0049] During assembly, the hook-shaped portions 1121 at both ends of the S-shaped spring are hooked onto the hook portions 1122 on the corresponding support beams 111, thereby horizontally fixing the S-shaped spring between the two support beams 111. This hook-and-hook connection method eliminates the need for screws, welding, or other complex fixing methods, making installation simple and quick, and facilitating subsequent maintenance or replacement of the S-shaped spring.

[0050] With the cooperation of the hook-shaped part 1121 and the hook part 1122, the overall structure of the elastic element 112 is more stable and reliable. Even during the repeated lifting and lowering of the back frame 11, the position of the S-shaped spring can be kept fixed, ensuring safety for long-term use.

[0051] In one embodiment, the support frame further includes a head frame 13, which is rotatably connected to the back frame 11; the drive mechanism further includes a head drive mechanism 22, which is connected to the head frame 13 and is used to drive the head frame 13 to rotate relative to the back frame 11.

[0052] In this embodiment, the head frame 13 is an extension of the support frame, used to support the user's head and neck area. The head frame 13 and the back frame 11 are connected by hinges, pivots, or other rotatable connectors, allowing the head frame 13 to rotate independently about the connection point, thus enabling angle adjustment of the head area relative to the back area. This independent connection design avoids the fixed angle limitation of traditional mattresses where the head and back are linked, providing greater adjustment freedom and better meeting ergonomic needs.

[0053] The head drive mechanism 22 can be an electric actuator, a combination of a motor and a linkage, or other drive devices well known to those skilled in the art, similar to but independently configured as the back drive mechanism 21. The head drive mechanism 22 is connected to the head frame 13; for example, its output end can be hinged to a force-bearing point on the side of the head frame 13 away from the back frame 11, while its fixed end is connected to the back frame 11. By activating the head drive mechanism 22, the head frame 13 can be driven to rotate upwards or downwards relative to the back frame 11, thus achieving the function of raising or lowering the head.

[0054] In practical use, this configuration allows users to independently adjust the angle of the head frame 13 without affecting the posture of the back frame 11. For example, when reading or watching, users can raise only the head frame 13 for more comfortable neck support. Simultaneously, the elastic element 112 on the back frame 11 allows the entire upper body support frame to better adapt to changes in user posture when both the head and back are adjusted, further reducing pressure and discomfort and improving overall comfort. Through independent control of the head drive mechanism 22, this embodiment effectively solves the problem of insufficient head adjustment freedom in the prior art, enabling more flexible multi-scenario applications.

[0055] In one embodiment, the support frame further includes a leg frame 14, which is rotatably connected to the seat frame 12; the drive mechanism further includes a leg drive mechanism 23, which is used to drive the leg frame 14 to rotate relative to the seat frame 12.

[0056] In this embodiment, the leg frame 14 is an extension of the support frame, used to support the user's legs and feet. The leg frame 14 and the seat frame 12 are connected in a rotatable manner via hinges, pivots, or other rotatable connectors, allowing the leg frame 14 to rotate independently about the connection point, thus enabling angle adjustment of the leg area relative to the seat area. This independent connection design can meet the user's support needs in different scenarios.

[0057] The leg drive mechanism 23 can be an electric push rod, a combination of a motor and a linkage, or other drive devices well known to those skilled in the art, similar to but independently configured as the back drive mechanism 21. The leg drive mechanism 23 is connected to the leg frame 14; for example, its output end can be hinged to a force-bearing point on the side of the leg frame 14 away from the seat frame 12, while its fixed end is connected to the seat frame 12. By activating the leg drive mechanism 23, the leg frame 14 can be driven to rotate upwards or downwards relative to the seat frame 12, thus achieving the function of raising or lowering the legs.

[0058] By adding a leg frame 14 and a leg drive mechanism 23, the mattress in this embodiment enables independent or coordinated adjustment of the back and legs. Users can adjust the back frame 11 or the leg frame 14 individually, or both simultaneously, to achieve a "zero-gravity" posture or other more personalized and comfortable body positions. Combined with the elastic element 112 of the back frame 11, the mattress provides continuous and comfortable support during dynamic adjustments, especially when the back is raised. The elastic element 112 effectively alleviates the pressure caused by body displacement, making the entire multi-zone adjustment process smoother and more ergonomic.

[0059] In one embodiment, the seat frame 12 includes a first seat 121 and a second seat 122 that can be folded relative to each other; the back frame 11 is rotatably connected to the first seat 121, and the leg frame 14 is rotatably connected to the second seat 122.

[0060] In this embodiment, the entire support frame is designed to be foldable for ease of packaging and transportation. The seat frame 12 is divided into two parts: a first seat portion 121 adjacent to the back frame 11 and a second seat portion 122 adjacent to the leg frame 14. The first seat portion 121 and the second seat portion 122 are connected by a hinge or similar folding structure, allowing the entire support frame to be folded in half in the seat area. This design reduces the length of the mattress in the folded state, making it easier for users to carry it upstairs.

[0061] Meanwhile, the back frame 11 is rotatably connected to the first seat portion 121 via a hinge; the leg frame 14 is also rotatably connected to the second seat portion 122 via a hinge. When the mattress is unfolded and in working condition, the first seat portion 121 and the second seat portion 122 together form a complete seat frame 12 for supporting the user's buttocks and nearby thigh area. When folding is required, folding is performed with the connection point of the first seat portion 121 and the second seat portion 122 as the folding axis. This segmented connection design ensures the feasibility of the folding function without affecting the independent adjustment function of each part (back and legs).

[0062] In one embodiment, a mattress body 30 is provided on top of the support frame, the mattress body 30 including at least one elastic layer.

[0063] In this embodiment, the support frame serves as the skeleton of the mattress, providing posture adjustment and basic support functions. To provide the user with a soft and comfortable lying experience, a mattress body 30 is also laid on top of the support frame. This mattress body 30 is in direct contact with the user's body.

[0064] The mattress body 30 includes at least one elastic layer. This elastic layer can be made of various materials, such as high-resilience foam, latex, or memory foam (e.g., cloud-feel memory foam). In a preferred embodiment, the mattress body 30 can be composed of multiple layers of elastic layers with different functions, for example, from top to bottom: a comfort layer (e.g., memory foam) providing a soft touch, and a support layer (e.g., high-resilience foam or latex pad) providing core support.

[0065] In this embodiment, a base frame 40 is also included, and the seat frame 12 is detachably connected to the top of the base frame 40.

[0066] In this embodiment, the bottom frame 40 is the lowest supporting structure of the entire mattress, providing stable basic support and balance. It is located below the support frame and is connected to the seat frame 12 via a detachable connection. This detachable connection can use bolts, plug-in connectors, or other quick-release structures, allowing the seat frame 12 (and the entire support frame) to be separated from or installed on the bottom frame 40.

[0067] This design simplifies mattress packaging, transportation, and after-sales maintenance. For example, during transportation, the entire mattress can be disassembled into two parts: the base frame 40 and the upper support frame, each packaged independently, reducing the overall volume. During home installation, assembly is quick and easy; simply attach the seat frame 12 to the top of the base frame 40 without the need for specialized tools.

[0068] In one embodiment, the bottom of the base frame 40 is provided with a plurality of bed legs 41.

[0069] In this embodiment, the bottom of the base frame 40 (i.e., the side away from the user) is provided with multiple bed legs 41, which are used to raise the entire mattress off the ground. The bed legs 41 can be cylindrical, square, or other shaped support legs, and are fixed to the bottom of the base frame 40 by bolts or plug-in methods. In a preferred configuration, the bottom of the base frame 40 is provided with four bed legs 41, which are located at the four corners of the base frame 40 to form a stable four-point support.

[0070] like Figure 7 As shown, corresponding to the above-mentioned anti-squeezing back mattress, this utility model embodiment also provides a bed, the bed 60 including the mattress 50 of any of the aforementioned embodiments.

[0071] In this embodiment, since the bed 60 uses the mattress described in the previous embodiment, it inherits all the advantages of that mattress. Specifically, when the user adjusts the backrest of the bed 60, the elastic element 112 on the mattress backrest frame 11 can elastically deform in response to the user's body pressure, effectively eliminating the feeling of pressure and making the entire adjustment process smoother and more comfortable. Simultaneously, the bed 60 can also have independent head and leg adjustment functions, meeting the personalized needs of users in various scenarios such as resting, reading, and watching videos.

[0072] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
