Description

Technical Field

[0001] This utility model relates to the field of mattresses, and more specifically to a bendable mattress core and mattress. Background Technology

[0002] As an indispensable household item in people's daily lives, the performance of mattresses directly affects people's rest experience. In the current mattress market, polyurethane foam and springs are the main materials used for mattress cores. However, the uniformity of the spring or polyurethane foam material in the same layer results in a highly consistent overall structure and uniform support performance, making it difficult to allow the mattress to bend. This fails to meet the differentiated support needs of different areas of the body, leading to poor body-to-mattress fit. It also limits the use of mattresses with bending functions such as electric bed frames, making it difficult to meet users' needs for improved sleep comfort and sleeping posture.

[0032] Example 1

[0033] See Figure 1 and Figure 2 As shown, this embodiment discloses a bendable mattress core 1, applied to a mattress 10. The bendable mattress core 1 of this embodiment includes: a support layer 11 made of sponge material; the upper surface of the support layer 11 is provided with a first support area 111, a second support area 112 and a third support area 113 along the length direction of the mattress core 1. The first support area 111, the second support area 112 and the third support area 113 are respectively provided with a plurality of first grooves 1111, second grooves 1121 and third grooves 1131. The distance between adjacent second grooves 1121 is greater than the distance between adjacent first grooves 1111 and the distance between adjacent third grooves 1131.

[0034] The bendable mattress core 1 of this embodiment divides the support layer 11 into a first support area 111, a second support area 112, and a third support area 113, and correspondingly opens grooves with different spacings. This improves the adaptability and deformation capacity of the mattress core 1 while ensuring overall support, thereby enhancing the bendability of the mattress 10. It can provide different support levels according to the weight differences of different parts of the body, thus meeting the differentiated support and comfort needs of different areas of the body. Specifically, when a person lies on the mattress 10 in a lying position, the mattress core 1 is compressed. Due to the greater weight in the waist and hip areas, the second grooves 1121 located in the middle of the support layer 11 are sparsely distributed, ensuring that the second support area 112 is used for… The larger sponge area supporting the human body provides better support, while the head, shoulders, and legs, being lighter, have their first groove 1111 and third groove 1131 closely distributed at both ends of the support layer 11, reducing the support force on the human body and making the first support area 111 and third support area 113 softer, providing a more comfortable effect. At the same time, compared with the traditional support structure of springs, sponges, or a combination of both, the sponge support layer 11 with the first groove 1111, second groove 1121, and third groove 1131 makes it easier for the mattress core 1 to bend, significantly improving its compatibility with devices that require bending functions, such as electric bed frames, helping users improve their sleeping posture and further enhancing their sleep experience.

[0035] In a further embodiment, see Figure 1 and Figure 2As shown, the first groove 1111, the second groove 1121, and the third groove 1131 penetrate the support layer 11 along the width direction of the mattress core 1. It can be understood that when the mattress core 1 is bent under force, the first groove 1111, the second groove 1121, and the third groove 1131 can fully stretch and compress with the change in the bending angle of the mattress core 1. Because the first groove 1111, the second groove 1121, and the third groove 1131 penetrate the support layer 11, the mattress core 1 can be subjected to more even force in the width direction. During bending, the deformation of each area of ​​the support layer 11 becomes more coordinated, reducing localized excessive stretching or compression, and improving the smoothness and stability of bending. Furthermore, when a person lies on the mattress 10, body pressure acts on the support layer 11. The first groove 1111, the second groove 1121, and the third groove 1131 that penetrate the support layer 11 will contract towards the middle of the support layer 11 due to the pressure. This causes the edge sponge of the support layer 11 in the width direction to be squeezed towards the middle, making the space of the first groove 1111, the second groove 1121, and the third groove 1131 smaller. Air is discharged from both ends of the grooves. When the pressure disappears, the first groove 1111, the second groove 1121, and the third groove 1131 return to their original shape, and air flows in again. Therefore, the first groove 1111, the second groove 1121, and the third groove 1131 form a relatively long through channel, which is conducive to the flow of air in the width direction of the mattress core 1, enhances air circulation, and improves the breathability of the mattress 10.

[0036] In a further embodiment, see Figure 1 and Figure 2 As shown, the first support area 111 and the third support area 113 are symmetrically arranged on both sides of the second support area 112. It can be understood that the first support area 111 and the third support area 113 have the same proportion in the length direction of the support layer 11, and the first groove 1111 and the third groove 1131 are also symmetrically arranged due to the symmetry of the first support area 111 and the third support area 113. When a person lies on the mattress 10, the weight of the head and shoulders acts on the first support area 111, and the weight below the legs acts on the third support area 113. Due to the symmetrical arrangement of the two areas and the relatively balanced weight distribution of the head, shoulders, and legs, the pressure on the first support area 111 and the third support area 113 is similar. This results in the first groove 1111 and the third groove 1131 having basically the same degree of deformation, and the support force output also remains symmetrical. This allows the overall support force of the support layer 11 to present a symmetrical distribution, which is compatible with the relatively balanced weight distribution of the human body's head, shoulders, and legs. This ensures that the support force of the first support area 111 and the third support area 113 matches the weight it bears, avoiding imbalance of force distribution and providing a good lying experience for the user. Furthermore, this symmetrical arrangement allows the support layer 11 to bear more even force, reducing localized excessive pressure.

[0037] In a further embodiment, see Figure 1 and Figure 2 As shown, the first support area 111, the second support area 112, and the third support area 113 are divided into three equal parts along the length of the mattress core 1. It can be understood that the length direction of the support layer 11 is consistent with the length direction of the mattress core 1, and the width direction of the support layer 11 is consistent with the width direction of the mattress core 1. The first support area 111 is located between the starting end of the support layer 11 and a distance of one-third of the length of the support layer 11 from the starting end; the second support area 112 is located between one-third and two-thirds of the length of the support layer 11 from the starting end; and the third support area 113 is located between two-thirds and the ending end of the support layer 11. This equal division design of the first, second, and third support areas 111 and 113 allows each support area to obtain a balanced deformation space when bent. When the mattress 10 is used with an electric bed frame and needs to be bent, the support layers 11 corresponding to the three support areas can deform according to preset requirements, improving the flexibility of the mattress core 1 when bent. For example, when the second support area 112 needs to be adjusted to accommodate the lumbar support requirements, the trisection structure allows the first support area 111 and the third support area 113 on either side of the second support area 112 to bend symmetrically during the protrusion process. This ensures the overall bending coordination and prevents overstretching or insufficient deformation due to one support area being too long or too short, thus helping to achieve the matching accuracy between the mattress 10 and the electric bed frame. It is understood that in other embodiments, the proportions of the first support area 111, the second support area 112, and the third support area 113 can be adjusted according to actual needs. For example, dividing the first support area 111, the second support area 112, and the third support area 113 in a 3:4:3 ratio can provide a larger area of ​​strong support for the hips and lower back.

[0038] In a preferred embodiment, see Figure 2As shown, several first grooves 1111 are evenly spaced, preferably with a distance of 2-3 cm between adjacent first grooves 1111. During the process of the user pressing down on the first support area 111 with their head and neck, the sponge corresponding to the first support area 111 bends at a large angle and has many bending surfaces, thus requiring a fine grooving method to accommodate the bending angle. Setting the distance between adjacent first grooves 1111 to 2-3 cm, this small-space design makes the sponge strips between the first grooves 1111 narrower, allowing them to easily bend and indent into the first grooves 1111 under pressure. This allows the first support area 111 to conform well to the contour of the head and neck. The first grooves 1111 also deform due to the compression of the sponge, with changes in depth and width, providing a soft and comfortable feeling for the head and neck. At the same time, this small-space design does not excessively weaken the support force of the support layer 11, ensuring softness while providing appropriate support for the head and neck, avoiding discomfort caused by insufficient support.

[0039] In a further embodiment, see Figure 2 As shown, several third grooves 1131 are evenly spaced. Preferably, the distance between adjacent third grooves 1131 is the same as the distance between adjacent first grooves 1111. When the legs and below of the human body press on the third support area 113, since the spacing between the third grooves 1131 is also the same as the spacing between the first grooves 1111 (i.e., 2-3 cm), the resulting deformation is similar to that of the first support area 111. This ensures that the support and bending characteristics of the first support area 111 and the third support area 113 are consistent. Users can change the usage direction of the mattress core 1, so that the first support area 111 is used to support the legs and below, and the third support area 113 is used to support the head and neck, improving the user's convenience and experience. Furthermore, the consistency between the spacing of the first grooves 1111 and the third grooves 1131 ensures that the air passages of the first support area 111 and the second support area 112 are distributed in the same way, making the air circulation effect of the first support area 111 and the second support area 112 consistent, and ensuring the overall uniformity of air permeability.

[0040] In a further embodiment, see Figure 2 As shown, several second grooves 1121 are evenly distributed, with a distance of 10-12 cm between adjacent second grooves 1121. The larger spacing allows for wider intervals between the sponge segments in the second support area 112, resulting in relatively smaller deformation under greater pressure from the hips and waist, maintaining good structural stability and providing strong support for the hips and waist, preventing insufficient support due to excessive deformation. The large spacing design of the second grooves 1121 retains a certain degree of flexibility in the support layer 11 to accommodate slight deformation, without weakening the support force due to overly dense grooves, perfectly meeting the high support requirements of the hips and waist.

[0041] Understandably, see Figure 2 As shown, the distance between adjacent second grooves 1121 is greater than the distance between adjacent first grooves 1111. To accommodate the wider distance, the width of the second groove 1121 is greater than the width of the first groove 1111. The width of the third groove 1131 is the same as or substantially the same as the width of the first groove 1111. The smaller size and smaller spacing of the first groove 1111 and the third groove 1131 allow for more flexible and subtle deformation of the first support area 111 and the third support area 113 during bending, significantly improving bending flexibility. The larger size and larger spacing of the second groove 1121 provide strong support while retaining a larger deformation space. During bending, the second support area 1121 provides stable support without excessively hindering the overall bending, making the overall bending of the mattress core 1 more coordinated and stable. The density design of the first groove 1111, the second groove 1121 and the third groove 1131 prevents problems such as bulging and wrinkling of the upper surface of the support layer 11 and the material above the support layer 11 when bending, thus providing support for a good user experience.

[0042] In a further embodiment, see Figure 2 As shown, the lower surface of the support layer 11 is provided with a plurality of deformation grooves 114 along the length of the mattress core 1. These deformation grooves 114 effectively reduce the possibility of the mattress core 1 breaking due to tensile stress when it is bent under stress. When the mattress core 1 is bent under stress, the deformation grooves 114 contract or stretch along the bending direction of the mattress core 1, cooperating with the first groove 1111, the second groove 1121, and the third groove 1131 on the upper surface, reducing bending resistance and improving the smoothness of bending the mattress core 1.

[0043] In a preferred embodiment, see Figure 2 As shown, the groove depth of the deformation groove 114 is 4-8 cm, and the groove width is 1-2 cm. Setting the groove depth of the deformation groove 114 to 4-8 cm allows for sufficient deformation space during bending. The groove width of 1-2 cm causes slight expansion or contraction under pressure or bending, resulting in a small change in groove width. Due to the narrow groove width, its variation range is limited, maintaining the overall structural stability of the support layer 11 and ensuring moderate flexibility of the lower surface of the support layer 11. This prevents the bending effect from being too shallow or the structural strength of the support layer 11 from being too deep, thus improving the reliability of bending. Furthermore, it ensures sufficient airflow space within the deformation groove 114, enhancing air circulation and further improving breathability.

[0044] It is understood that the groove depths of the plurality of deformation grooves 114 may be consistent or inconsistent. In a preferred embodiment, such as this embodiment, the groove depths of the plurality of deformation grooves 114 are inconsistent. More specifically, the deformation grooves 114 on the lower surface of the support layer 11 have two depths, and the two different depths of deformation grooves 114 are arranged alternately. Figure 2 As shown, the deformation groove 114 includes a fourth groove 1141 and a fifth groove 1142, with the fifth groove 1142 having a greater depth than the fourth groove 1141. The deformation grooves 114 of different depths play different roles when the mattress core 1 is bent. For example, the shallower fourth groove 1141 can deform first when the mattress core 1 undergoes a small bend, absorbing some stress and allowing the mattress core 1 to adapt to the initial bending action more easily. The deeper fifth groove 1142, on the other hand, provides greater deformation space when the mattress core 1 needs to be bent more significantly, further alleviating stress concentration and allowing the mattress core 1 to complete a more smooth bend without being damaged by excessive pressure. This layered deformation mechanism greatly improves the adaptability of the support layer 11 to different degrees of bending and enhances the flexibility of the mattress core 1.

[0045] It is also understood that the groove shapes of the plurality of deformation grooves 114 may be identical or inconsistent. In a preferred embodiment, such as this embodiment, the groove shapes of the plurality of deformation grooves 114 are inconsistent. More specifically, the deformation grooves 114 on the lower surface of the support layer 11 have two groove shapes, and the deformation grooves 114 with the two different groove shapes are arranged alternately. Figure 2 As shown, the fourth groove 1141 is a square groove, and the fifth groove 1142 is a combination of a square groove and a circular groove. That is, the end of the fifth groove 1142 furthest from its opening is a circular groove, and the end closest to its opening is a square groove connected to the circular groove. Under different usage scenarios or bending requirements, the way the fourth groove 1141 and the fifth groove 1142 distribute stress also differs. For example, a square groove can evenly distribute stress in four directions when subjected to force, while the combination of the square and circular grooves in the fifth groove 1142 combines the stability of a square groove with the arc-shaped stress-dispersing characteristics of a circular groove. This allows for more effective stress dispersion into the surrounding foam, reducing the risk of localized damage and improving the adaptability of the support layer 11 to different pressure distributions.

[0046] In a further embodiment, see Figure 2 As shown, the distance between adjacent deformation grooves 114 is greater than the distance between adjacent second grooves 1121. It can be understood that the distribution of deformation grooves 114 on the lower surface of the support layer 11 is sparser than the distribution of second grooves 1121 in the second support area 112 on the upper surface. This makes the support structure on the lower surface of the support layer 11 more stable, preventing insufficient support due to overly dense deformation grooves 114 during bending, thus improving the overall pressure-bearing capacity of the mattress core 1.

[0047] In a preferred embodiment, see Figure 2 As shown, the distance between adjacent deformation grooves 114 is 16cm. The 16cm interval makes the distribution of deformation grooves 114 sparse, which allows the lower surface of the support layer 11 to provide greater support and ensure the overall structural stability of the mattress core 1. At the same time, this spacing ensures that the sponge between adjacent deformation grooves 114 can form an effective force transmission chain. When a certain area is subjected to force, the pressure can be orderly diffused to the surrounding deformation groove 114 area through the sponge, avoiding local stress concentration and achieving a seamless connection from precise local support to uniform overall force distribution, thereby improving the comfort of the mattress core 1.

[0048] In a further embodiment, see Figure 2 As shown, the deformation groove 114 penetrates the support layer 11 along the width direction of the mattress core 1. The through-type deformation groove 114 improves the bending flexibility of the support layer 11. When bending the mattress core 1 along its length direction, for example, by lifting the area corresponding to the starting end of the support layer 11, so that the first support area 111 is bent relative to the second support area 112, the lower surface of the support layer 11 is stretched. The groove walls of the deformation groove 114 along the length direction of the support layer 11 will gradually extend to both sides, and the width of the groove opening will also increase to a certain extent due to the stretching. At the same time, the groove depth of the fourth groove 1141 will become shallower. Furthermore, due to the unevenness of the overall bending and stretching, the deformation degree of the fourth groove 1141 near the bending center may be greater than that away from the bending center, so that the lower surface of the support layer 11 can adapt to the folding changes of the mattress core 1. In addition, the deformation groove 114 on the lower surface and the first groove 1111, the second groove 1121 and the third groove 1131 on the upper surface form a vertically continuous air passage, which increases the air circulation channel. When the user lies down, the support layer 11 is compressed, which can build an air circulation system and greatly improve the air permeability of the mattress core 1.

[0049] In a preferred embodiment, see Figure 2 As shown, the support layer 11 is an integrated structure made of polyurethane high-support foam. Polyurethane high-support foam possesses excellent support performance and resilience, effectively dispersing pressure and ensuring comfort and stability during use. Compared to traditional spring mattresses, it is lightweight and easier to move. The integrated structure avoids the gap problems caused by splicing multiple foam pieces, not only enhancing the overall strength and durability of the support layer 11 but also preventing gaps from affecting support performance and usability, greatly improving the quality and lifespan of the mattress core 1.

[0050] In a further embodiment, see Figure 2 and Figure 3As shown, the bendable mattress core 1 also includes a cushioning layer 12. The cushioning layer 12 is positioned above the support layer 11 and has several ventilation holes 121 and / or ventilation channels 122. The cushioning layer 12, placed above the support layer 11, creates a multi-layered structure for the mattress core 1. The cushioning layer 12 is designed to enhance user comfort, further optimizing the firmness of the mattress core 1. It also acts as a buffer between the support layer 11 and the human body, preventing direct contact between the body and the support layer 11, reducing discomfort that may result from the material properties of the support layer 11, and providing a softer touch for the user. The design of the ventilation holes 121 and / or ventilation channels 122 breaks the relatively closed spatial structure inside the cushioning layer 12. When the mattress core 1 is pressed down by the weight of the human body, the heat and moisture generated by the body can be quickly dissipated through these ventilation holes 121 and / or form good air convection, improve the breathability of the mattress core 1, help keep the mattress core 1 dry and comfortable, and create a healthy sleep environment for the user.

[0051] In a further embodiment, see Figure 2 and Figure 3 As shown, the buffer layer 12 includes a first buffer portion 123, and a plurality of vent holes 121 are evenly distributed on the first buffer portion 123. Preferably, the first buffer portion 123 is made of latex material; the vent holes 121 are round holes. Latex material has the characteristics of being mite-proof, antibacterial, and having good resilience. In addition, latex itself has good noise reduction properties, resulting in minimal noise from turning over during sleep, thus providing users with a healthy and comfortable sleep environment. The evenly distributed round holes can accelerate air circulation, effectively expelling moisture and heat generated during sleep, and improving sleep quality.

[0052] In a further embodiment, see Figure 2 and Figure 3 As shown, the cushioning layer 12 includes a second cushioning portion 124, and a plurality of ventilation grooves 122 are disposed on the second cushioning portion 124. Preferably, the second cushioning portion 124 is made of soft sponge material. Soft sponge material is soft and skin-friendly, conforms to the curves of the human body, provides a soft wrapping feeling to the body, and reduces body pressure, while the design of the ventilation grooves 122 further enhances the breathability of the mattress core 1, avoids stuffiness, and keeps the user cool and comfortable during sleep.

[0053] In a further embodiment, see Figure 2 and Figure 3As shown, several ventilation grooves 122 are staggered along the length and width of the mattress core 1 on the second cushioning part 124, dividing the second cushioning part 124 into several protrusions 125. It can be understood that the ventilation grooves 122 and the protrusions 125 give the second cushioning part 124 a chocolate-like shape, constructing a multi-dimensional and orderly three-dimensional ventilation network. This greatly increases the contact area between air and the mattress core 1, allowing air to circulate more freely within the mattress core 1, significantly improving ventilation efficiency. Meanwhile, the protrusions 125 provide a better granular massage sensation to the body, promoting blood circulation, relieving physical fatigue, and further optimizing the sleep experience.

[0054] In a further embodiment, see Figure 2 As shown, the bendable mattress core 1 also includes a filling layer 13; the filling layer 13 is located below the support layer 11. The filling layer 13, located below the support layer 11, acts as a buffer and softener, further dispersing the pressure of the body on the mattress core 1. Simultaneously, when adapted to the bending of an electric bed frame, the filling layer 13 can deform along with the support layer 11, reducing internal stress concentration, lowering the risk of damage to the mattress core 1, and extending its service life.

[0055] Example 2

[0056] See Figure 1 and Figure 2 As shown, this embodiment discloses a mattress 10, including: an outer cover 2 and a bendable mattress core 1 as described in Embodiment 1; the outer cover 2 is wrapped around the bendable mattress core 1.

[0057] The mattress 10 in this embodiment is equipped with a bendable mattress core 1, which can perfectly match the various angle adjustment functions of the electric bed frame. Whether it is raising the head, raising the legs, or bending the whole body, the mattress 10 can smoothly follow.
