Description

Mattress and electric bed using the same Technical Field

[0001] The present invention relates to the field of bedding, in particular to a mattress and an electric bed using the mattress. Background Art

[0002] Existing mattresses are often equipped with airbag structures based on user needs. The airbag structure includes an airbag assembly and a control box that controls the air pressure within the airbag assembly. By adjusting the air pressure within the airbag assembly, the softness and hardness can be adjusted to provide comfortable support for the user. The mattress includes a cushion body and an outer cover that wraps the cushion body. The cushion body includes a base layer, a sponge layer disposed on the base layer, and a comfort layer disposed on the sponge layer. Existing mattresses have the following problems:

[0003] 1. The sponge layer is an integrated structure, in which unit grooves for installing the control box and the airbag assembly are formed by hollowing out and cutting. The sponge processing process is complicated and easily scrapped due to cutting errors, resulting in high processing costs and low processing efficiency.

[0004] 2. The control box is equipped with pipelines connected to various functional parts, and the pipelines are scattered on the surface of the sponge layer. The pipelines are easily damaged due to repeated bending, and the air path may be blocked due to local compression, affecting the user experience.

[0005] 3. When the outer cover needs to be opened for disassembly and repair of a local area of ​​the mattress, the various layers of the mattress will spread out due to the loss of the outer cover. The user needs to re-install the mattress after completing the repair and resetting it. This not only increases the difficulty of assembly and the length of repair, but also increases the maintenance cost. In addition, the mattress comfort and user experience will be affected due to misalignment and other errors during assembly.

[0006] 4. The frame of the mattress body is generally square, and the frame includes two transverse edges (i.e., the second edges) and a longitudinal edge (i.e., the first edge) spanning the corresponding ends of the two transverse edges. The longitudinal edges have flat top and bottom edges. When the mattress is bent in conjunction with the electric bed, it is easy for the longitudinal edges to fail to bend synchronously with the mattress body and become detached from the mattress body. The top surface of the mattress body and the edges are misaligned, resulting in an uneven top surface of the mattress, which affects both the comfort of use and the visual effect and overall quality of the mattress. Summary of the Invention

[0007] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art and to provide a mattress and an electric bed using the same, which utilizes a plurality of sponge blocks to assemble to form an assembly cavity and a wiring channel, thereby protecting the functional parts and pipelines, reducing the processing difficulty of the sponge layer, improving the assembly / processing efficiency, and reducing the processing cost by reducing waste; in addition, by providing an upper cavity and a lower cavity to independently wrap the comfort layer, the functional layer and the base layer, respectively, it is ensured that the various parts of the mattress body can be quickly maintained and reset through independent disassembly and assembly, and the assembly operation is effectively simplified; by providing a groove on the first side edge of the mattress, etc., the first side edge and the mattress body are prevented from being misaligned when bending, which is beneficial to improving the comfort of use and the visual effect and quality of the mattress.

[0008] The above technical objectives of the present invention are mainly solved by the following technical solutions: A mattress, comprising a base layer and a sponge layer arranged above the base layer, the sponge layer comprising a plurality of sponge blocks and functional parts, characterized in that the sponge blocks are stacked and assembled to enclose and form an assembly cavity for hiding the functional parts and a wiring channel spanning the assembly cavity, and the functional parts are connected by pipelines laid along the wiring channel. The sponge blocks are independently processed and stacked to form assembly cavities and wiring channels, which effectively simplifies the difficulty of sponge block processing, improves processing efficiency, reduces waste caused by incorrect cutting, and effectively reduces processing costs. It also provides assembly cavities and wiring channels for convenient embedded assembly of various functional parts and pipelines, plays a role in positioning and protecting the functional parts and pipelines, and effectively improves the user experience.

[0009] As a further improvement and supplement to the above-mentioned technical solution, the present invention employs the following technical measures: the wiring channel comprises an air channel arranged along the side of the sponge layer and an electrical channel arranged along the middle of the sponge layer. The functional components include an airbag assembly, a sensing assembly, and a control box. The control box and the airbag assembly are connected by air pipes running along the air channel, and the control box and the sensing assembly are connected by electrical wires running along the electrical channel. The air channel is used for routing the air pipe, leaving ample space for the pipe to prevent blockage caused by compression and deformation. The electrical wires are routed along a predetermined path to prevent damage from repeated bending. The air channel and electrical wires are independently located to effectively prevent interference and ensure proper operation of the air and electrical wires. The sensing assembly and the control box are connected by electrical wires, which provide power and signal transmission. The airbag assembly and the control box are connected by air pipes, allowing the control box to control the air pressure within the airbag assembly, thereby adjusting the cushion's firmness.

[0010] The sponge block includes a lower block disposed at the rear of the sponge layer, and a front block and a rear block disposed above the lower block and separated front and rear. The front block is a split structure and includes two symmetrically arranged unit blocks; the assembly cavity includes a first cavity for embedding and installing the control box. The middle of the top surface of the lower block forms a limiting groove by downward depression. The space enclosed by the limiting groove of the lower block, the rear edge of the front block, and the front edge of the rear block, and the space enclosed between the unit block and the rear block form the first cavity. The front block and the rear block are respectively disposed at the front edge and the rear edge of the top surface of the lower block, so that the rear side wall of the front block, the front side wall of the rear block, and the middle of the top surface of the lower block enclose to form a first cavity for embedding and positioning the control box. During processing, there is no need to hollow out the lower block, the front block, and the rear block, which reduces the processing difficulty, effectively improves the processing efficiency, and also reduces the processing cost by reducing waste products. The limiting groove is for the vertical embedding of the bottom of the control box, which plays a role in vertically supporting and horizontally limiting the control box. The front block and the rear block are separated in front of and behind the control box, which not only plays a role in horizontally limiting the control box, but also ensures that the rear part of the sponge layer has a flat top surface, effectively eliminates the foreign body sensation, ensures that the comfort layer is laid flat above the sponge layer, and improves the lying comfort. The front block is divided into unit blocks for independent processing, which can not only play a role in positioning the control box, but also play a role in supporting the comfort layer, and can also form a circuit channel for laying wires between the unit blocks, effectively shortening the circuit laying distance.

[0011] The unit block is in a U-shaped with an opening facing the rear, and the rear block is in an E-shaped with an opening facing the front. The openings of the unit block and the rear block face each other and form the side wall of the first cavity; alternatively, the space enclosed between the opposite sides of the unit block and the front edge of the rear block forms a T-shaped circuit channel, and both ends of the circuit channel are respectively connected to the corresponding first cavity and extend forward at the other end and are connected to the induction component; alternatively, the induction component is disposed on the top surface of the airbag component. There are two openings for the control box to be clamped and positioned on the front side wall of the rear block, and there is an opening for the control box to be clamped and positioned on the rear side wall of the unit block. By setting the openings facing each other to enclose and form the side wall of the first cavity, it plays a role in horizontally limiting the control box. One end of the wire is connected to the control box disposed in the first cavity, and the other end sequentially passes through the gap between the rear block and the unit block and the gap between the unit blocks and then is connected to the induction component or an external power source, ensuring that the wire is embedded and hidden in the circuit channel, which plays a role in limiting and protecting the wire.

[0012] The sponge block includes a central limit block disposed in the middle of the sponge layer and a front limit block disposed in front of the sponge layer. The assembly cavity also includes a second cavity disposed between the central limit block and the front limit block and for embedding and installing the airbag assembly. The airbag assembly is clamped and positioned between the front limit block and the central limit block, or the airbag assembly is adhered and fixed to the top surface of the base layer via Velcro provided on the bottom surface of the airbag cover. The central limit block and the front limit block are separated in a front-to-back direction and enclose a second cavity for installing the airbag assembly therebetween. The central limit block and the front limit block not only clamp and position the airbag assembly in a front-to-back direction, but are also arranged at the same height as the top surface of the airbag assembly to ensure that the comfort layer can be laid flatly.

[0013] The mattress includes an annular perimeter, and the air passage is L-shaped, comprising a transverse section formed by the front and rear edges of the rear and front blocks, and a longitudinal section formed by the side edges of the front blocks, the side edges of the central stopper, and the perimeter. The air passage is positioned along the unit blocks near the edges of the base layer, effectively avoiding the area of ​​the sponge layer that supports the user and preventing the air passage from deforming under pressure and causing tracheal collapse and blockage. The transverse and longitudinal sections are connected to form an L-shaped air passage, with both ends of the air passage spanning the first and second chambers, respectively, facilitating tracheal connection between the control box and the airbag assembly.

[0014] The side edge of the front block and the surrounding edge together form a partial longitudinal section, and the longitudinal section is formed by the front block and the surrounding edge; or, the side edge of the middle limit block is provided with a through groove running through the front and back, and the through groove and the surrounding edge together form a partial longitudinal section, the through groove is arranged at the bottom edge of the side wall of the middle limit block, and is formed by the surrounding edge. The longitudinal section does not require hollowing out the sponge layer, which is convenient for processing. The longitudinal section setting method can also use the deformation of the sponge layer itself to offset the weight of the user, thereby protecting the trachea; or, the surrounding edge completely covers the side walls of the base layer and the sponge layer, which not only plays a role in horizontally limiting the sponge layer and the base layer, but also is used to shield the sponge layer and the side walls of the base layer to improve the aesthetics.

[0015] The mattress also includes an outer cover and a cushion body disposed within the outer cover. The cushion body includes an inner cover, a comfort layer, a functional layer, and a base layer. The inner cavity of the inner cover includes an upper cavity and a lower cavity separated by a partition. The comfort layer is enclosed in the upper cavity, and the functional layer and base layer are enclosed in the lower cavity. The functional layer includes the base layer and the sponge layer, and the comfort layer is disposed on the sponge layer. The comfort layer, functional layer, and base layer are respectively enclosed in the upper and lower cavities, providing each layer with a dedicated installation location, effectively improving production assembly efficiency and installation accuracy, and reducing the possibility of installation misalignment. Each layer can also be independently disassembled as needed for maintenance, ensuring that only the components to be repaired are disassembled and assembled, improving maintenance efficiency and user experience.

[0016] The inner cover includes a built-in upper cover and a built-in lower cover connected to the interlayer via a zipper. The interlayer is connected to the built-in upper cover and the built-in lower cover respectively via a zipper, thereby enclosing the upper and lower cavities. The functional layer and the base layer are vertically stacked and tightly wrapped by the built-in lower cover and the interlayer to limit the deformation of the functional layer and the base layer. A heating pad installed via a zipper is provided on the top surface of the inner cover. The outer cover includes an external upper cover and an external lower cover, which are connected by a zipper and completely wrap the pad body. The built-in upper cover and the built-in lower cover are connected by an interlayer, so that the upper inner cover and the lower inner cover can be independently disassembled and the upper or lower cavity can be opened independently, which facilitates independent maintenance of the components in the upper or lower cavity, ensures that the intact components are always tightly wrapped and precisely positioned, and prevents assembly offset due to disassembly. The functional layer and base layer are stacked vertically to form a rectangular parallelepiped that can be tightly enclosed by the lower cavity. This ensures that the functional layer and base layer are vertically aligned and prevent horizontal offset between them. The heating pad is removably mounted on the top surface of the inner cover, allowing for efficient disassembly and maintenance of the heating pad by opening the outer cover without opening the inner cover, ensuring the relative positions of the comfort layer, functional layer, and base layer are fixed. The outer upper cover and the outer lower cover are independently manufactured and connected by a zipper, facilitating processing and assembly while also providing protection for the pad and the heating pad mounted on its top surface.

[0017] The airbag assemblies comprise at least two equal-height cubes, arranged sequentially along the front-to-back direction of the functional layer. Each airbag assembly comprises a capsule body and an airbag cover enclosing the capsule body. Adjacent airbag assemblies are connected via zippers located at the corresponding top and bottom edges of the airbag cover. The sequential arrangement of the airbag assemblies creates a flat top surface, enhancing sleeping comfort and facilitating quick and precise assembly and disassembly. Adjacent airbag assemblies are connected via zippers, ensuring connection reliability and improving assembly precision, aligning them at equal heights during zipper connection. The airbag cover protects the capsule body and facilitates zipper installation, allowing for precise positioning of the capsule body.

[0018] The surrounding edge includes two first surrounding edges, which are respectively arranged on both sides of the mattress in the longitudinal direction. A plurality of grooves are arranged at the upper end of the first surrounding edge, and the grooves penetrate the first surrounding edge along the thickness direction of the first surrounding edge. At least the grooves are arranged on the first surrounding edge, so that when the mattress is bent in the longitudinal direction, the first surrounding edge can bend synchronously with the cushion body, avoiding misalignment between the first surrounding edge and the cushion body, and can always keep the top surface of the first surrounding edge and the top surface of the cushion body on the same plane / curved surface, which is beneficial to improving the comfort of use and the visual effect and quality of the mattress. The arrangement of the grooves on the first surrounding edge is compatible with the arrangement of the folding plate on the bed board. The folding plate pushes the mattress to bend, and the deformation of the grooves changes the force on the first surrounding edge, which facilitates the first surrounding edge to bend synchronously with the cushion body, and keeps the top surface of the first surrounding edge and the upper surface of the cushion body on the curved surface.

[0019] When the mattress bends, the tangent of the bend is often parallel to the width of the mattress, that is, parallel to the second surrounding edge of the mattress. To this end, a plurality of grooves are provided on the upper edge of the first surrounding edge. The grooves are arranged in parallel. The grooves are cylindrical with an open groove at the top. The open groove is located at the upper edge of the first surrounding edge and is exposed. The grooves are connected to the space above the first surrounding edge through the open groove. Along the length of the first surrounding edge, from one end of the first surrounding edge to the other end of the first surrounding edge, the diameter of the groove gradually increases from small to large and then gradually decreases from large to small, and this cycle repeats at least twice. The provision of the open grooves and the opening at the upper edge of the first surrounding edge facilitate smooth bending of the first surrounding edge and help maintain the flatness of the top surface of the first surrounding edge.

[0020] To further enable the first edge to bend smoothly along the length of the mattress, a plurality of deformable holes are provided in the middle portion of the first edge. These deformable holes are arranged along the length of the first edge, and each deformable hole extends through the thickness of the first edge. Along the length of the first edge, from one end to the other, the cross-sectional dimensions of the deformable holes gradually increase from small to large and then decrease from large to small, repeating this cycle at least twice. If the corresponding portion of the first edge bends less, the groove diameter is smaller. Conversely, if the corresponding portion of the first edge bends more, the groove diameter is larger. The deformable holes are provided to free up space, facilitating the bending of the first edge. The edge material at the bending portion presses against the deformable holes, freeing up space. The corresponding material on the edge then occupies the space freed by the deformation of the deformable holes, thereby facilitating the bending of the first edge.

[0021] The distances between the head end and the end of the first surrounding edge and the adjacent groove are L1 and L2, 165mm≤L1≤170mm, 170mm≤L2≤175mm; the distance between the lower edge of the groove and the first surrounding edge is the height H of the groove, 15mm≤H≤25mm, and the distance between adjacent grooves is A, 43mm≤A≤64mm; the distances between the head end and the end of the first surrounding edge and the adjacent deformable through hole are L3 and L4, 660mm≤L3≤680mm, 270mm≤L4≤360mm.

[0022] When the mattress bends, a certain length remains flat at both ends, providing support for the head, back, and legs. The bend is often located in the middle of the mattress's length, allowing twisting forces to be applied smoothly to the grooves. The height H of the groove from the top of the first side surround is the depth of the groove, which corresponds to the bending amplitude of the first side surround: a larger bending amplitude results in a deeper groove; a smaller bending amplitude results in a shallower groove. The distance between the deformable holes and the mattress ends also ensures a certain length remains flat at both ends, providing support for the head, back, and legs.

[0023] To ensure smoother bending of the first edge, the distance from the bottom edge of the groove to the first edge is the groove height H, which ranges from 15mm ≤ H ≤ 25mm. The distance between adjacent grooves is A, which ranges from 43mm ≤ A ≤ 64mm. The groove depth is determined by the height H of the groove from the top of the first edge. The groove depth corresponds to the bending amplitude of the first edge: a larger bending amplitude results in a deeper groove; a smaller bending amplitude results in a shallower groove.

[0024] Preferably, the first surrounding edge is provided with a plurality of cutting lines, the two walls of which are bonded together by an adhesive structure. The cutting lines are provided in a one-to-one correspondence with the deformable through holes. The lower openings of the cutting lines are located at the lower edge of the first surrounding edge, and the upper openings of the cutting lines are connected to the deformable through holes. The deformable through holes are cylindrical, with a diameter B of 15 mm ≤ B ≤ 75 mm. The distance between adjacent cutting lines is C, with a distance C of 20 mm ≤ C ≤ 80 mm. The provision of the cutting lines facilitates cutting the deformable through holes in the first surrounding edge, and the bonding of the two walls of the cutting lines by the adhesive structure helps to improve the strength of the first surrounding edge.

[0025] An electric bed includes a bed plate and a mattress arranged on the bed plate, characterized in that it also includes a power drive mechanism, wherein the bed plate includes at least a fixed plate, a first flip plate pivotally connected to one end of the fixed plate, and / or a second flip plate pivotally connected to the other end of the fixed plate, the power drive mechanism is used to drive the first flip plate and / or the second flip plate to flip or lay flat, and the mattress is the aforementioned bendable mattress, and flipping or laying flat the first flip plate and / or the second flip plate causes the mattress to bend or lay flat. A mattress whose edges bend along with the mattress body is arranged on a bed plate with a folding plate, and the folding plate is driven by the power drive mechanism to flip upward, thereby pushing the corresponding part of the mattress to bend upward, and structures such as the grooves and deformation through holes on the first edge help the first edge to bend smoothly and synchronously with the mattress body, always keeping the upper surface of the mattress flat, which not only helps to improve user comfort, but also helps to improve the overall visual effect and overall quality.

[0026] The present invention has the following beneficial effects: 1. The sponge blocks are independently processed and stacked to form assembly cavities and wiring channels, which effectively simplifies the difficulty of sponge block processing, improves processing efficiency, and reduces waste caused by incorrect cutting. It can also provide convenient embedded assembly cavities and wiring channels for various functional parts and pipelines, positioning and protecting the functional parts and pipelines, and effectively improving the user experience. 2. An inner cover with an upper cavity and a lower cavity is provided in the outer cover, and the comfort layer, functional layer, and base layer are respectively wrapped in the upper cavity and the lower cavity, which not only groups the components and sets up exclusive installation chambers, but also effectively improves production and assembly efficiency, improves installation accuracy, and prevents installation misalignment. It can also independently disassemble each component according to maintenance needs to ensure that only the components to be repaired are disassembled and assembled, thereby improving maintenance efficiency and user experience. 3. A groove is provided on at least the first surrounding edge. When the mattress is bent in the length direction, the first surrounding edge can bend synchronously with the mattress body, and the top surface of the first surrounding edge and the top surface of the mattress body can always be kept on the same plane / curved surface, which is beneficial to improving the comfort of use and the visual effect and quality of the mattress.

Modes for Carrying Out the Invention

[0043] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0044] Example 1: As shown in Figures 1-6, a mattress comprises a base layer 114 and a sponge layer disposed above the base layer 114. The sponge layer includes a plurality of sponge blocks 213 and functional components. The sponge blocks 213 are stacked and assembled to form an assembly cavity for hiding the functional components and a wiring channel 217 spanning the assembly cavity. The functional components are connected via pipelines laid along the wiring channel 217. The sponge blocks 213 are independently processed and stacked to form the assembly cavity and wiring channel 217. This effectively simplifies the processing of the sponge blocks 213, eliminates the need for hollowing operations, improves processing efficiency, and reduces waste due to incorrect cutting. It also provides an assembly cavity and wiring channel 217 for convenient embedded assembly of the functional components and pipelines, positioning and protecting the functional components and pipelines, effectively improving the user experience. Furthermore, by stacking the sponge blocks 213, a sponge layer with a flat surface is obtained, facilitating assembly of the sponge layer within the mattress.

[0045] In actual operation, the wiring channel 217 includes an air path channel 101 arranged along the side of the sponge layer and a circuit channel 102 arranged along the middle of the sponge layer. The functional parts include an airbag assembly 103, a sensing assembly and a control box 104. The control box 104 is arranged at the rear of the sponge layer, effectively away from the user's head, thereby reducing the impact of the operation of the control box 104 on the user's sleep. The airbag assembly 103 is arranged at the front of the sponge layer and can support and adjust each part of the user's torso so that each part of the user's torso can obtain appropriate support. The sensing assembly is arranged on the top surface of the sponge layer, which facilitates the sensing assembly to monitor the specific position of the user, thereby obtaining the user's physiological data and position data, etc. The control box 104 and the airbag assembly 103 are connected through an air tube laid along the air path channel 101, so that the control box 104 can adjust the air pressure in the airbag assembly 103 through the air tube, thereby adjusting the hardness of the airbag assembly 103. The control box 104 is connected to the sensing component via wires laid along the circuit channel 102 . The control box 104 provides the sensing component with power required for operation and receives signals from the sensing component via the wires.

[0046] In actual operation, the sponge block 213 is a plurality of sponge layers that can be stacked to form a rectangular parallelepiped shape. It can not only overlap the base layer 114 with its flat bottom surface, but also provide comfortable support for the user with its flat top surface. The sponge block 213 includes a lower block 105 arranged at the rear of the sponge layer, and a front block and a rear block 106 arranged above the lower block 105 and arranged front and back. It also includes a central limit block 110 arranged in the middle of the sponge layer and a front limit block 111 arranged at the front of the sponge layer. The vertical projections of the central limit block 110 and the front limit block 111 fall completely into the base layer 114, ensuring that the sponge layer and the base layer 114 are vertically stacked and form a rectangular parallelepiped shape.

[0047] In actual operation, the assembly cavity includes a first cavity 107 (as shown in Figure 3) for the control box 104 to be embedded and installed. The middle part of the top surface of the lower block 105 forms a limiting groove 109 by being recessed downward (as shown in Figure 6). The first cavity 107 is formed by enclosing between the limiting groove 109 of the lower block 105, the trailing edge of the front block, and the leading edge of the rear block 106. The assembly cavity further includes a second cavity 112 provided between the middle limiting block 110 and the front limiting block 111 for the airbag assembly 103 to be embedded and installed. The first cavity 107 and the second cavity 112 are respectively used to install the control box 104 and the airbag assembly 103 (as shown in Figure 5). It ensures that the control box 104 and the airbag assembly 103 are clamped and positioned by the adjacent sponge blocks 213 after being installed in place, effectively restricting the control box 104 and the airbag assembly 103 from shifting due to external forces, not only ensuring that the air pipe can be effectively connected and preventing disconnection, but also effectively reducing noise and improving the use experience. The front block, the rear block 106, the middle limiting block 110, and the front limiting block 111 are all formed by independent cutting, and both the first cavity 107 and the second cavity 112 are formed by the sponge blocks 213 enclosing, eliminating the operation of hollow cutting.

[0048] In actual operation, an air path channel 101 formed by enclosing the sponge blocks 213 along the way is provided between the first cavity 107 and the second cavity 112. The air pipe is laid along the air path channel 101 to ensure the air path connection between the control box 104 and the airbag assembly 103, not only preventing the end of the air pipe from detaching from the control box 104 or the airbag assembly 103 due to the force-induced offset of the air pipe, but also preventing the air pipe from being blocked due to the pressure-induced deformation.

[0049] In actual operation, the front block is a split structure, including two unit blocks 108 symmetrically arranged, so as to form two symmetrically arranged first cavities 107 between the unit blocks 108 and the rear block 106. Specifically, the unit block 108 is in a U-shaped with an opening facing backward, and the rear block 106 is in an E-shaped with an opening facing forward. The openings of the unit block 108 and the rear block 106 face each other and form the side walls of the first cavity 107. The openings of the unit block 108 and the rear block 106 face each other and enclose to form the first cavity 107, not only ensuring that the inner contour of the first cavity 107 matches the control box 104, but also improving the limiting effect by eliminating the gap between the control box 104 and the wall surface of the first cavity 107.

[0050] In actual operation, the facing sides of the unit blocks 108 and the front edge of the rear block 106 enclose a T-shaped circuit channel 102 (as shown in Figure 4). The two ends of the circuit channel 102 are connected to the corresponding first cavity 107, and the other end extends forward and connects to the sensing component. The front block includes two separate unit blocks 108. This ensures that each unit block 108 can enclose the first cavity 107 with the rear block 106, while also leaving gaps between the unit blocks 108 and between the unit blocks 108 and the rear block 106. The T-shaped circuit channel 102 is enclosed, facilitating the routing of wires and bridging the control box 104 and the sensing component.

[0051] In actual operation, the mattress includes an annular edge 113 that completely covers the base layer 114 and the side walls of the sponge layer. The air passage 101 is L-shaped, comprising a horizontal section formed by the front edge of the rear block 106 and the rear edge of the front block, and a vertical section formed by the side edges of the front block, the side edges of the central stopper 110, and the edge 113. Placing the air passage 101 along the edge of the sponge layer not only facilitates enclosing the sponge block 213, but also avoids the user's lying area, preventing tracheal blockage due to compression and deformation.

[0052] In actual operation, the side edge of the front block and the surrounding edge 113 together form a partial longitudinal section, and the side edge of the central limit block 110 is provided with a through groove running through the front and back, and the through groove and the surrounding edge 113 together form a partial longitudinal section. The above-mentioned partial longitudinal sections are formed into a complete longitudinal section through corresponding connections, which is convenient for the laying of the trachea and the connection with the airbag assembly 103.

[0053] Example 2: As shown in Figures 7-11, a mattress that is easily disassembled and assembled comprises an outer cover 201 and a cushion body 202 disposed within the outer cover 201. The cushion body 202 includes an inner cover, a comfort layer 203, a functional layer 204, and a base layer 114. The inner cavity of the inner cover comprises an upper cavity and a lower cavity separated by a partition 205. The comfort layer 203 is enclosed within the upper cavity, while the functional layer 204 and base layer 114 are enclosed within the lower cavity. An inner cover with upper and lower cavities is disposed within the outer cover 201. The comfort layer 203 is disposed within the upper cavity, while the functional layer and base layer 114 are disposed within the lower cavity.

[0054] In practice, since each component group has an independent chamber, users can disassemble the corresponding chamber to inspect and repair the corresponding component. Specifically: the inner cover is installed in the outer cover 201, and the heating pad 208 can be inspected and maintained by removing the outer cover 201; the comfort layer 203 is installed in the upper chamber and can be inspected by removing the outer cover 201 and the inner upper cover 206; the functional layer 204 and the base layer 114 are stacked and enclosed in the lower chamber and can be inspected and repaired by removing the outer cover 201 and the inner lower cover 207.

[0055] In actual operation, the inner cover includes an internal upper cover 206 and an internal lower cover 207 connected to the interlayer 205 via zippers. The interlayer 205 is connected to the internal upper cover 206 and the internal lower cover 207 via zippers, thereby enclosing the upper and lower chambers. Two sets of vertically offset zippers are provided around the periphery of the interlayer 205. The interlayer 205 is connected to the corresponding internal upper and internal lower covers 207 via the two sets of zippers, so that the interlayer 205, the internal upper cover 206, and the internal lower cover 207 are connected to form the upper and lower chambers, which not only facilitates the disassembly and maintenance of the cushion body 202, but also ensures that parts that do not require maintenance are always effectively wrapped and positioned, reducing the workload of disassembly and assembly.

[0056] In actual operation, the functional layer 204 and base layer 114 are vertically stacked and tightly wrapped by the built-in lower cover 7 and the spacer 205 to limit deformation of the functional layer 204 and base layer 114. The functional layer 204 and base layer 114 are stacked and form a rectangular parallelepiped, matching the contour of the lower cavity. This acts as a position limiter for the functional layer 204 and base layer 114, ensuring that their vertical projections coincide with each other.

[0057] In actual operation, a heating pad 208 is provided on the top surface of the inner cover and is installed via a zipper. The heating pad 208 is located between the inner cover and the outer cover 201. The outer cover 201 is used to shield and protect the heating pad 208, and the heat generated by the heating pad 208 can be smoothly transferred upwards, making it convenient for the user to keep warm.

[0058] In actual operation, the outer cover 201 includes an outer upper cover 209 and an outer lower cover 210, which are connected by a zipper and completely enclose the cushion body 202. The zippered connection of the outer upper cover 209 and the outer lower cover 210 completely encloses the cushion body 202, making it easy to disassemble and clean the cushion body 202 independently, reducing the cleaning workload by reducing the frequency of cleaning, and also protecting the cushion body 202.

[0059] In practice, the functional layer 204 includes an airbag adjustment unit and a control unit, separated by a front-to-back arrangement. The airbag adjustment unit houses the airbag assembly 103, while the control unit houses the control box 104, which regulates the air pressure within the airbag assembly 103. The front-to-back arrangement of the control unit and airbag adjustment unit effectively utilizes the space within the functional layer 204. Furthermore, by placing the control unit at the rear of the functional layer 204, it increases the distance from the user's head, thereby minimizing the impact of the control box 104 on the user's sleep. The control unit adjusts the air pressure within the airbag assembly to adjust the hardness of the functional layer, thus meeting the diverse needs of users.

[0060] In actual operation, the airbag adjustment part includes a front limit block 111 and a middle limit block 110 which are arranged in a front and rear direction. The airbag assembly 103 is clamped and positioned between the front limit block 111 and the middle limit block 110. The front limit block 111 and the middle limit block 110 are used to clamp and position the airbag assembly 103, which not only ensures that the components are tightly arranged to prevent offset, but also ensures that the top surface of the airbag adjustment part is flat, thereby improving the user's lying comfort.

[0061] In actual operation, there are at least two airbag assemblies 103 in the shape of cubes of equal height. The airbag assemblies 103 are arranged in sequence along the front-to-back direction of the functional layer 204. The corresponding side walls of adjacent airbag assemblies 103 are connected by a zipper. The airbag assembly 103 includes a bag body and an airbag cover that wraps the bag body. Adjacent airbag assemblies 103 are connected by zippers provided at the corresponding top and bottom edges of the airbag cover. Adjacent airbag assemblies 103 are fixed and limited by two sets of zippers to ensure that the relative positions of the two airbag assemblies 103 are fixed and fixed, thereby preventing displacement and deflection between adjacent airbag assemblies 103.

[0062] In actual operation, the airbag adjustment unit includes a base layer 114 positioned below the airbag assembly 103. The base layer 114 supports and secures the airbag assembly, ensuring its tight arrangement and ensuring that its top surfaces are aligned and aligned smoothly. The airbag assembly 103 is adhered and secured to the top surface of the base layer 114 via Velcro 214 located on the bottom surface of the airbag cover. Each airbag assembly 103 is adhered and secured to the base layer 114 via the Velcro 214, securing the relative positions of the airbag assemblies 103 and ensuring a secure bond between the airbag assemblies 103 and the base layer 114, preventing them from vertically separating from the base layer 114. The airbag cover is provided with an opening that is opened and closed by a zipper, through which the airbag assembly 103 is removably mounted within the cover.

[0063] In actual operation, the control unit includes several sponge blocks 213. The control box 104 is connected to the airbag assembly 103 and the heating pad 8 via pipelines laid along the wiring channel 217. The sponge blocks 213 provide a locking, positioning, and protective wrapping for the control box 104 and the pipelines. The pipelines include the wires between the control box 104 and the heating pad 8, and the air tubes between the control box 104 and the airbag body.

[0064] Example 3: As shown in Figures 12-14, the surrounding edge 113 includes two first surrounding edges 302, one of which is provided on either side of the length of the mattress body 202. A plurality of grooves 304 are provided at the upper end of each first surrounding edge 302, extending through the first surrounding edge 302 along its thickness. The provision of grooves 304 on at least one first surrounding edge 302 allows the first surrounding edges 302 to bend synchronously with the mattress body 202 when the mattress is bent in its length, preventing misalignment between the first surrounding edges 302 and the mattress body 202. This ensures that the top surfaces of the first surrounding edges 302 and the mattress body 202 are always aligned on the same plane / curved surface, improving both user comfort and the visual quality of the mattress. The setting mode of the groove 304 on the first edge 302 is adapted to the setting mode of the folding plate on the bed board 309. The mattress is pushed to bend by the folding plate, and the deformation of the groove 304 changes the force on the first edge 302, making it convenient for the first edge 302 to bend synchronously with the cushion body 202, keeping the top surface of the first edge 302 and the upper surface of the cushion body 202 on the curved surface.

[0065] To further explain, the groove 304 is provided at the upper edge of the first surrounding edge 302. The distances L1 and L2 between the first and end of the first surrounding edge 302 and the adjacent groove 304, respectively, are 165mm≤L1≤170mm, and 170mm≤L2≤175mm. When a mattress bends, a certain length at each end remains flat and unbends to support the head, back, and legs. The bending area is often located in the middle of the mattress's length. To ensure that twisting forces during bending are smoothly applied to the groove 304, the groove 304 is positioned a certain distance from the ends. The groove 304 is omitted within a considerable length at each end, which also helps save time and reduces manufacturing costs.

[0066] When the mattress bends, the tangent line of the bend tends to be parallel to the width of the mattress, that is, parallel to the second surrounding edge 303 of the mattress. To this end, a plurality of grooves 304 are arranged in parallel. Each groove 304 is cylindrical with an open slot 305 at the top. The open slot 305 is located at the upper edge of the first surrounding edge 302 and is exposed. The open slot 305 connects the groove 304 with the space above the first surrounding edge 302. The provision of the open slot 305 and its opening at the upper edge of the first surrounding edge 302 facilitates smooth bending of the first surrounding edge 302 and helps maintain the flatness of the top surface of the first surrounding edge 302.

[0067] To ensure smooth bending of the first edge 302 along the length of the mattress, the diameter of the groove 304 is gradually increased from one end of the first edge 302 to the other end, and this cycle is repeated at least twice. If the corresponding portion of the first edge 302 bends less, the diameter of the groove 304 will be smaller. Conversely, if the corresponding portion of the first edge 302 bends more, the diameter of the groove 304 will be larger.

[0068] To facilitate smoother bending of the first peripheral edge 302, the distance from the bottom edge of the groove 304 to the first peripheral edge 302 is defined as the height H of the groove 304, with a range of 15mm≤H≤25mm. The distance between adjacent grooves 304 is defined as A, with a range of 43mm≤A≤64mm. The height H of the groove 304 from the top of the first peripheral edge 302 is defined as the depth of the groove first peripheral edge 304. The depth of the groove first peripheral edge 304 corresponds to the bending amplitude of the first peripheral edge 302. A greater bending amplitude of the first peripheral edge 302 results in a deeper groove 304; a smaller bending amplitude results in a shallower groove 304.

[0069] To further facilitate bending of the first surrounding edge 302, a plurality of deformable through-holes 306 are provided in the middle of the first surrounding edge 302. These deformable through-holes 306 are arranged along the length of the first surrounding edge 302, and each of the deformable through-holes 306 extends through the thickness of the first surrounding edge 302. The deformable through-holes 306 are provided to free up space, facilitating bending of the first surrounding edge 302. The surrounding material at the bending portion presses against the deformable through-holes 306, freeing up space. The corresponding material on the surrounding edge then occupies the space freed by the deformable through-holes 306, thereby facilitating bending of the first surrounding edge 302.

[0070] In actual applications, the distances between the first and last ends of the first peripheral edge 302 and the adjacent deformable through-holes 306 are L3 and L4, respectively, with 660mm≤L3≤680mm and 270mm≤L4≤360mm. The distances between the deformable through-holes 306 and the two ends of the mattress are also designed to ensure that the mattress has a certain length at both ends to remain flat and unbendable, thereby supporting the head, back, and legs. At the same time, L3 is greater than L1, and L4 is greater than L2, with the magnitude of the difference being adapted to the thickness of the mattress. This allows the mattress to bend so that the bending portion corresponds to the pivot point of the folding plate on the bed board 309, and reduces the number of deformable through-holes. This, combined with the placement of grooves at a certain distance from both ends and the reduction in the number of grooves, also helps save time and reduce manufacturing costs.

[0071] Preferably, in order to conform to the bending of the first surrounding edge 302, along the length direction of the first surrounding edge 302, from one end of the first surrounding edge 302 to the other end of the first surrounding edge 302, the cross-sectional size of the deformable through hole 306 gradually increases from small to large, and then gradually decreases from large to small, and this cycle is repeated at least twice, so that the mattress is adapted to the foldable bed board on the electric bed, and the hole diameter is large where the bending rate is large, and the hole diameter is small where the bending rate is small.

[0072] To facilitate the smooth and effective placement of the deformable holes 306, several cutting lines 307 are provided on the first peripheral edge 302. The two walls of each cutting line 307 are bonded together via an adhesive structure. Each cutting line 307 corresponds to each deformable hole 306. The lower opening of each cutting line 7 is located at the lower edge of the first peripheral edge 302, and the upper opening of each cutting line 307 communicates with the deformable hole 6. Each deformable hole 306 is cylindrical, with a diameter B of 15 mm ≤ B ≤ 75 mm. The distance between adjacent cutting lines 307 is C, with a distance C of 20 mm ≤ C ≤ 80 mm. The provision of cutting lines 307 facilitates the cutting of the deformable holes 306 in the first peripheral edge 302. The bonding structure bonds the two walls of each cutting line 307 together, thereby enhancing the strength of the first peripheral edge 302. The bonding structure can be a bonding layer formed by the curing of various adhesives, or alternatively, double-sided tape.

[0073] Example 4: As shown in Figures 12-15 , an electric bed is a technical solution to another technical theme of the present invention. The electric bed includes a bed frame 308, a bed board 309 mounted on the bed frame 308, a power drive mechanism 314 engaged with the bed board 309, and a mattress mounted on the bed board 309. The power drive mechanism 314 drives the bed board 309 to partially tilt upward or flatten.

[0074] The bed board 309 includes at least a fixed plate 310 fixed on the bed frame 308, a first flip plate 311 pivoted to one end of the fixed plate 310 and / or a second flip plate 312 pivoted to the other end of the fixed plate 310, the power drive mechanism 314 is used to drive the first flip plate 311 and / or the second flip plate 312 to flip up or lie flat, the mattress is the above-mentioned flexible mattress, and the first flip plate 311 and / or the second flip plate 312 flip up or lie flat so that the mattress is bent or laid flat.

[0075] The mattress described in the first technical solution of the present invention is placed on a bed board 309 with a folding plate. Driven by a power drive mechanism 314, the first folding plate 311 and / or the second folding plate 312 flip upward, bending one or both ends of the mattress upward. The grooves 304 and deformable holes 306 on the first edge 302 help the first edge 302 bend smoothly and synchronously with the mattress body 202, maintaining a flat top surface and enhancing user comfort.

[0076] In this embodiment, the bed board 309 further includes a third flip plate 313, one end of which is pivotally connected to one end of the fixed board 310, and a second flip plate 312 is pivotally connected to the other end of the third flip plate 313. The second flip plate 312 and the first flip plate 311 correspond to the two ends of the mattress, respectively. The fixed board 310 and the third flip plate 313 are located in the middle of the bed board 309. The first flip plate 311 is flipped up to position the user's head and shoulders in a sitting or semi-reclining position, while the third flip plate is flipped up to lift the user's legs. The second flip plate is located at the outer end of the third flip plate. When in a nearly flat position, it is used to rest the user's calves, facilitating relaxation.
