DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0048] In the present application, the terms "upper", "lower", and the like indicate the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0049] In addition, the above-mentioned partial terms can be used to represent other meanings in addition to the orientation or positional relationship, for example, the term "upper" can also be used to represent a certain dependent relationship or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in this application can be understood according to the specific circumstances.

[0050] In addition, the terms "set", "connected" should be broadly understood. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or internal communication between two devices, elements or components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0051] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of "multiple" is two or more.

[0052] Too soft and too hard mattress will cause the spine twist, and choose soft and hard mattress, the user's body can get full support, help to adapt to the human body curve, the degree of spinal twist is also the smallest.

[0053] The support layer structure mainly affects the softness and hardness of the entire mattress, and springs are usually used as support layer materials, for example, whole-face springs or independent pocket springs.

[0054] In the related art, the spring is fixed in the mattress, so that the hardness of the mattress is set at the time of factory shipment. If you want to change the hardness of the mattress, you can only replace the springs in the mattress as a whole, but this way is more troublesome to operate, affecting the user's experience.

[0055] Therefore, the application discloses a softness-adjustable mattress, a mattress assembly and a bed.

[0056] In addition, the mattress of the application is also connected with an adjusting assembly, the driving part of the adjusting assembly can drive the lifting part to move the first linkage assembly along the first direction, so as to change the compression degree of the first linkage assembly to the elastic member, and the adjusting assembly is arranged to realize the electric control of the movement of the first linkage assembly, so as to help improve the convenience and accuracy of the softness adjustment of the mattress.

[0057] The technical solutions of the application will be further described below with reference to the embodiments and the drawings.

[0058] Please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic view of the mattress disclosed by the embodiments of the application, Figure 2 is a structural schematic view of the mattress from another perspective disclosed by the embodiments of the application. The softness-adjustable mattress comprises a mattress frame 1, a first linkage assembly 3, a second linkage assembly 2 and an elastic member 4. The mattress frame 1 is formed with a mounting space 11, the mounting space 11 has an upward opening, the first linkage assembly 3 is located in the mounting space 11, and along the first direction X, the first linkage assembly 3 is movably arranged at the bottom of the mounting space 11. The second linkage assembly 2 is at least partially located in the mounting space 11, and along the first direction X, the second linkage assembly 2 is arranged corresponding to the first linkage assembly 3 and located above the first linkage assembly 3. Along the first direction X, the elastic member 4 is located between the first linkage assembly 3 and the second linkage assembly 2, and one end of the elastic member 4 is connected to the first linkage assembly 3, and the other end is connected to the second linkage assembly 2. The first linkage assembly 3 is configured to be movable along the first direction X to change the compression degree of the elastic member 4. The first direction X is the height direction of the mattress frame 1.

[0059] By arranging the elastic member 4 between the first linkage assembly 3 and the second linkage assembly 2 along the first direction X, and connecting the two ends of the elastic member 4 with the first linkage assembly 3 and the second linkage assembly 2 respectively, the compression degree of the elastic member 4 by the first linkage assembly 3 can be adjusted by adjusting the position of the first linkage assembly 3 along the first direction X, so as to change the elastic force of the elastic member 4, and further help to change the softness of the overall mattress 100. For example, the more the first linkage assembly 3 moves upward along the first direction X (i.e. upward along the paper surface direction as shown in the figure), that is, the closer the first linkage assembly 3 moves to the direction of the second linkage assembly 2, the greater the compression degree of the elastic member 4, and the harder the touch of the elastic member 4. When the second linkage assembly 2 is compressed, the compressibility of the elastic member 4 is smaller, so as to increase the hardness of the overall mattress 100. Conversely, the less the first linkage assembly 3 moves upward along the first direction X, the smaller the compression degree of the elastic member 4, and the softer the touch of the elastic member 4, so as to make the overall mattress 100 softer. Figure 1

[0060] It can be understood that the coverage of the first linkage assembly 3 or the second linkage assembly 2 on the mattress frame 1 can be integral coverage or split coverage. Taking the integral coverage as an example, the size of the first linkage assembly 3 or the second linkage assembly 2 is substantially matched with the size of the mattress frame 1, and the projection of the first linkage assembly 3 or the second linkage assembly 2 on the bottom surface of the mattress frame 1 is substantially coincident with the bottom surface of the mattress frame 1. That is, the first linkage assembly 3 or the second linkage assembly 2 is a block structure. Such an integral structure helps to improve the processing simplicity of the first linkage assembly 3 and the second linkage assembly 2, and helps to directly adjust the overall first linkage assembly 3, which helps to improve the convenience of adjusting the softness of the mattress 100 compared with the structure of multiple split first linkage assemblies 3. At this time, the elastic member 4 can be a whole spring or a plurality of independent coil springs connected together.

[0061] Taking the split type as an example, a plurality of first linkage assemblies 3 or second linkage assemblies 2 are arranged along the length or width direction of the mattress frame 1, each first linkage assembly 3 or second linkage assembly 2 is a long strip, and each first linkage assembly 3 can move along the first direction X. Such a split structure helps to adjust the position of each first linkage assembly 3 along the first direction X respectively, so as to adjust the compression degree of the elastic member 4 at different positions respectively, and helps to improve the flexibility of the softness of the mattress 100, which can be adjusted in zones. At this time, the elastic member 4 can be an independent coil spring.

[0062] In this embodiment, the first linkage assembly 3 and the second linkage assembly 2 are both split type, and the elastic member 4 is an independent coil spring as a subsequent unfolding mode.

[0063] It can be understood that the material of the mattress frame 1 can be wood, iron, steel, etc., which is not limited in this embodiment.​

[0064] In addition, in order to improve the lying comfort of the user, a comfort layer can also be arranged on the upper surface of the second linkage assembly 2, and the material of the comfort layer can be latex, sponge, etc. The present embodiment does not make specific limitation on this.

[0065] In some embodiments, please refer to Figure 1 and Figure 2 , in combination with Figure 3 and Figure 4 , Figure 3 is a side view of the mattress frame disclosed in the embodiments of the present application, Figure 4 is Figure 2 the partial enlarged view of A in FIG. 1. The first limiting portion 12 is arranged on the side wall of the mattress frame 1, and the first limiting portion 12 is configured to limit the movement range of the first linkage assembly 3 along the first direction X. By arranging the first limiting portion 12 to limit the movement range of the first linkage assembly 3 along the first direction X, it is helpful to avoid the collision between the first linkage assembly 3 and the second linkage assembly 2 due to the excessive movement of the first linkage assembly 3 along the first direction X, and to avoid the damage of the elastic member 4 due to the excessive compression of the elastic member 4.

[0066] Optionally, please refer to Figure 1 and Figure 2 , in combination with Figure 5 , Figure 5 is Figure 2 the partial enlarged view of B in FIG. 1. The second limiting portion 13 is arranged on the side wall of the mattress frame 1, and the second limiting portion 13 is configured to limit the movement range of the second linkage assembly 2 along the first direction X. By arranging the second limiting portion 13 to limit the movement range of the second linkage assembly 2 along the first direction X, on the one hand, it is helpful to provide a certain sagging range when a person lies on the second linkage assembly 2, and on the other hand, it is helpful to keep the position of the second linkage assembly 2 when the first linkage assembly 3 moves along the first direction X, so as to avoid the movement of the second linkage assembly 2.

[0067] In some embodiments, please refer to Figure 1 and Figure 2 , in combination with Figure 3 and Figure 4, the first limiting part 12 comprises a groove part provided on the side edge of the mattress frame 1 along the first direction X, the groove part is arranged adjacent to the bottom of the mattress frame 1, and the first linkage assembly 3 is arranged in the groove part. By arranging the groove part on the side edge of the mattress frame 1, the first linkage assembly 3 is arranged in the groove part, which helps to guide the movement of the first linkage assembly 3 along the first direction X through the groove part, so that the movement path of the first linkage assembly 3 is more accurate. On the other hand, it helps to limit the movement range of the first linkage assembly 3 along the first direction X through the groove part. In addition, since the first linkage assembly 3 is arranged in the groove part, the user can adjust the part of the first linkage assembly 3 located outside the mattress frame 1, so that the first linkage assembly 3 can move along the first direction X.

[0068] Optionally, referring to Figure 1 and Figure 2 , in combination with Figure 5 , the second limiting part 13 comprises a first sub-limiting part 131 and a second sub-limiting part 132, the first sub-limiting part 131 is arranged at the top end of the side wall of the mattress frame 1, and the second sub-limiting part 132 is arranged on the side wall of the mattress frame 1 and is located below the first sub-limiting part 131 along the first direction X. The first sub-limiting part 131 and the second sub-limiting part 132 are located in the installation space 11 and extend from the mattress frame 1 into the installation space 11. When the first linkage assembly 3 moves along the first direction X, the first linkage assembly 3 will generate an upward force on the elastic member 4, and the elastic member 4 will also generate an upward force on the second linkage assembly 2. At this time, the first sub-limiting part 131 limits the second linkage assembly 2 to avoid upward movement of the second linkage assembly 2. When the human body lies on the upper surface of the second linkage assembly 2, a downward force will be generated on the second linkage assembly 2. At this time, the second sub-limiting part 132 limits the second linkage assembly 2 to avoid excessive downward movement of the second linkage assembly 2 and collision with the first linkage assembly 3, or to avoid increasing the compression degree of the elastic member 4 and causing damage to the elastic member 4.

[0069] It can be understood that the first sub-limiting part 131 and the second sub-limiting part 132 described above can be limiting strips, limiting blocks, etc., which are not specifically limited in the embodiment.

[0070] In some embodiments, referring to Figure 1 and Figure 2In the first direction X, the sum of the distances that the first linkage assembly 3 and the second linkage assembly 2 can move is less than the distance between the end of the first linkage assembly 3 close to the second linkage assembly 2 and the end of the second linkage assembly 2 close to the first linkage assembly 3. The distance between the end of the first linkage assembly 3 close to the second linkage assembly 2 and the end of the second linkage assembly 2 close to the first linkage assembly 3 is the distance that the elastic member 4 can be compressed. By making the sum of the distances that the first linkage assembly 3 and the second linkage assembly 2 can move less than the distance that the elastic member 4 can be compressed, it helps the second linkage assembly 2 to move downward in the first direction X when the first linkage assembly 3 moves upward to the maximum displacement in the first direction X and the user lies on the upper surface of the second linkage assembly 2, so as to provide a certain sag range for the user.

[0071] In some embodiments, referring to Figure 1 and Figure 2 in combination with Figure 6 , Figure 6 is a top view of the mattress disclosed in the embodiments of the present application. The first linkage assembly 3 and the second linkage assembly 2 are both provided in plurality. The plurality of first linkage assemblies 3 are arranged at intervals in the third direction Y, and each second linkage assembly 2 is arranged corresponding to the first linkage assembly 3. The second direction Z and the third direction Y intersect. By arranging the plurality of first linkage assemblies 3 at intervals in the direction intersecting the extension direction of the first linkage assembly 3, it helps to make the hardness of the extension direction of each first linkage assembly 3 uniform, and the hardness between each first linkage assembly 3 adjustable, thereby helping to make the mattress 100 adjustable in hardness in different zones.

[0072] It can be understood that the above-mentioned second direction Z and third direction Y can be the length or width direction of the mattress frame 1, and there can be various embodiments. In one example, the second direction Z is the length direction of the mattress frame 1, and the third direction Y is the width direction of the mattress frame 1. At this time, the first linkage assembly 3 extends in the length direction of the mattress frame 1, and a plurality of first linkage assemblies 3 are arranged at intervals in the width direction of the mattress frame 1, which helps to realize the uniform hardness in the length direction of the mattress frame 1 and adjustable hardness in the width direction of the mattress frame 1.

[0073] In another example, the second direction Z is the width direction of the mattress frame 1, and the third direction Y is the length direction of the mattress frame 1. At this time, the first linkage assembly 3 extends in the width direction of the mattress frame 1, and a plurality of first linkage assemblies 3 are arranged at intervals in the length direction of the mattress frame 1, which helps to realize the uniform hardness in the width direction of the mattress frame 1 and adjustable hardness in the length direction of the mattress frame 1.

[0074] In some embodiments, referring to Figure 1 and Figure 2 in combination with Figure 7 , Figure 7Fig. 1 is a structural schematic diagram of a first support block and a second support block disclosed by the embodiment of the present application. The first linkage assembly 3 comprises a first connecting rod 31 and a plurality of first support blocks 32 arranged at intervals along a second direction Z, and the first support block 32 is provided with a first mounting hole 321 arranged near the lower end of the first support block 32. The first connecting rod 31 is arranged through the plurality of first mounting holes 321 along the second direction Z, so that the plurality of first support blocks 32 are connected by the first connecting rod 31. It is helpful to simultaneously adjust the positions of the plurality of first support blocks 32 arranged through the first connecting rod 31 by adjusting the position of the first connecting rod 31 along the first direction X, and then it is helpful to ensure that the compression degrees of the plurality of elastic members 4 corresponding to the plurality of first support blocks 32 along the second direction Z are the same, so as to realize the uniform hardness along the second direction Z. The end of the first connecting rod 31 is located in the first limiting portion 12, so that the movement range of the first connecting rod 31 along the first direction X is limited by the first limiting portion 12. It is helpful to limit the movement range of the plurality of first support blocks 32 on the first connecting rod 31 along the first direction X by limiting the first connecting rod 31 by the first limiting portion 12, so as to avoid the case that the compression degree of the elastic member 4 by the plurality of first support blocks 32 is too large to cause damage to the elastic member 4.

[0075] The second linkage assembly 2 comprises a second connecting rod 21 and a plurality of second support blocks 22 arranged at intervals along the second direction Z, and the second support block 22 is provided with a second mounting hole 221. The second connecting rod 21 is arranged through the plurality of second mounting holes 221 along the second direction Z, so that the plurality of second support blocks 22 are connected by the second connecting rod 21, and then it is helpful to ensure that the positions of the plurality of second support blocks 22 along the first direction X are the same. Along the first direction X, each second support block 22 is arranged in one-to-one correspondence with each first support block 32, which is helpful to make each first support block 32 move along the first direction X relative to the corresponding second support block 22, so as to adjust the compression degree of the elastic member 4 at this position and avoid the case that the force in the mattress 100 is uneven. The second connecting rod 21 is arranged in the second limiting portion 13 and is clamped with the first sub-limiting portion 131 or the second sub-limiting portion 132, so that the movement range of the second connecting rod 21 along the first direction X is limited by the second limiting portion 13. It is helpful to limit the movement range of the plurality of second support blocks 22 on the second connecting rod 21 along the first direction X by limiting the second connecting rod 21 by the second limiting portion 13, so as to avoid the case that the compression degree of the elastic member 4 by the plurality of second support blocks 22 is too large to cause damage to the elastic member 4. The second direction Z can be the length direction or the width direction of the frame body of the bed frame 301, which can be set according to actual needs, and the embodiment does not make specific limitation.

[0076] It can be understood that, since the first connecting rod 31 and the plurality of first support blocks 32 will move along the first direction X, in order to ensure the movement stability and stress stability of the plurality of first support blocks 32 on the first connecting rod 31, the first connecting rod 31 can be a long rod with a square or rectangular cross section, and correspondingly, the second connecting rod 21 can also be a long rod with a circular, square or rectangular cross section, etc.

[0077] Correspondingly, the shape of the first mounting hole 321 can be square or rectangular, and the shape of the second mounting hole 221 can also be circular, square or rectangular, etc.

[0078] Optionally, the plurality of elastic members 4 are respectively arranged between the first support block 32 and the second support block 22 and connected with the corresponding first support block 32 and second support block 22. The first support block 32, the elastic member 4 and the second support block 22 are arranged one by one, which helps each first support block 32 to move along the first direction X relative to the corresponding second support block 22, so as to adjust the compression degree of the elastic member 4 at this position, and avoid the uneven stress in the mattress 100.

[0079] It can be understood that the upper side of the second support block 22 is a surface for the user to lie and sleep, and therefore the material of the second support block 22 can be softwood, memory cotton or other flexible materials. The materials of the first support block 32 and the second support block 22 can be the same or different, and the present embodiment does not make specific limitations thereon.

[0080] It can be understood that the materials of the first connecting rod 31 and the second connecting rod 21 can be the same as the material of the mattress frame 1, and the present embodiment does not make specific limitations thereon.

[0081] It can be understood that the elastic member 4 is an independent cylinder spring, and each spring is externally covered with a fabric layer, which helps to prevent mutual interference between the springs. The fabric layer can be non-woven fabric or polyester fiber, and the present embodiment does not make specific limitations thereon.
