[0043] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0044] Please see Figures 1 to 3 This application provides a mattress 100, which includes a mattress base 1, a knee airbag assembly 2, and an air source assembly 3.

[0045] The mattress base 1 can be square, for example, rectangular flat. It is understood that the mattress base 1 includes a knee area 1a, a torso area 1b, a leg area 1c, and a head area 1d. When the user lies flat on the mattress 100, the knee area 1a, torso area 1b, leg area 1c, and head area 1d correspond to the user's knees, torso, legs, and head, respectively. The knee area 1a is at least partially located within the leg area 1c.

[0046] The knee airbag assembly 2 is located in the knee region 1a. The knee airbag assembly 2 is used to inflate when inflated and to deflate when deflated, so that the knee airbag assembly 2 is used to controllably support the user's knee.

[0047] The air source component 3 is located on the mattress base 1 and is in fluid communication with the knee airbag component 2. The air source component 3 is used to inflate and deflate the knee airbag component 2. Please refer to [link / reference]. Figure 4 The air source component 3 includes an air valve assembly 31 and an air pump 32. The air valve assembly 31 controls the opening and closing of the air passage between the air pump 32 and the knee airbag assembly 2, thereby controlling whether the knee airbag assembly 2 is inflated. The air valve assembly 31 also has a vent (not shown), which is used to control the opening and closing of the air passage between the vent and the knee airbag assembly 2, thereby controlling the deflation of the knee airbag assembly 2. When the air passage between the knee airbag assembly 2 and the air pump 32 and the vent is disconnected, the knee airbag assembly 2 is in a pressure-holding state, which can be either inflated to support the user's knee or in a deflated state.

[0048] The knee airbag assembly 2 inflates and deflates under the action of the air source assembly 3, providing support for the user's knee when needed, allowing the knee to lift upwards and the hip bone to rotate backwards, thereby simultaneously releasing the muscles in the user's lower back and the back of the knee. This improves the problem of muscle tension in the user's lower back and the back of the knee, enhances the user's sleep comfort, and alleviates the muscle soreness caused by the mattress 100.

[0049] For the knee airbag assembly 2 mentioned above, please refer to Figure 5The knee airbag assembly 2 includes multiple knee sub-airbags 21, arranged sequentially along the length of the mattress base 1. It is understandable that when the knee airbag assembly 2 includes only one large airbag, the inflated height of the knee airbag assembly 2 is relatively high, and the top is curved, resulting in a small contact area with the user's knee and excessive support height, leading to a poor user experience. Reducing the inflation volume of the knee airbag assembly 2 can decrease its inflated height and increase the contact area with the user, but this results in insufficient support and a poor user experience. By using multiple knee sub-airbags 21, the top of the inflated knee airbag assembly 2 forms a supporting plane, and the inflated height of each individual knee sub-airbag 21 is reduced, thus lowering the overall inflated height of the knee airbag assembly 2. This increases the contact area between the knee airbag assembly 2 and the user's knee while reducing the support height, improving the user experience. Optionally, the knee airbag assembly 2 includes three knee sub-airbags 21.

[0050] It is understandable that the length of the mattress base 1 is the length of the user's body when the user lies flat on the mattress 100 in the preset sleeping position. The preset sleeping position is the position intended for the user to lie flat when the mattress 100 is manufactured. When the user lies flat in the preset sleeping position, they usually have the best sleep experience.

[0051] In some embodiments, please refer to Figure 5 The knee airbag assembly 2 also includes a first layer 22, on which multiple knee sub-airbags 21 are arranged sequentially and at intervals along the length of the mattress base 1. The multiple knee sub-airbags 21 are connected as a single unit through the first layer 22, thus fixing their relative positions and facilitating the arrangement and disassembly of the knee airbag assembly 2. Optionally, the first layer 22 may be a rubber layer or a rigid plastic plate.

[0052] In some other embodiments, please refer to Figure 5 The knee airbag assembly 2 includes a first layer 22 and multiple second layers 23. The multiple second layers 23 are sequentially spaced apart from the first layer 22 along the length of the mattress base 1, forming a sealed cavity with the first layer 22. Exemplarily, the edges of the second layers 23 are bonded to the first layer 22, for example, by adhesive or heat-pressing, thereby forming a sealed cavity between the first layer 22 and the second layers 23, thus forming the knee sub-airbag 21. Forming the knee airbag assembly 2 by bonding layered materials reduces the production cost of the knee airbag assembly 2; and the multiple knee sub-airbags 21 are connected as one unit through the first layer 22, making the positions of the multiple knee sub-airbags 21 relatively fixed, facilitating the arrangement and disassembly of the knee airbag assembly 2. Optionally, the first layer 22 and the second layer 23 are rubber layers.

[0053] In some embodiments, multiple knee sub-airbags 21 are fluidly connected to the air source assembly 3, which independently controls the inflation and deflation of each knee sub-airbag 21. By independently controlling the inflation and deflation of each knee sub-airbag 21, the knee airbag assembly 2 can adjust its support position according to the user's knee position, improving the problem of the knee airbag assembly 2's support position being inaccurate or failing to support the user's knee. For example, different users have different heights. Taking the user's head position as being aligned with the head area 1d of the mattress base 1, taller users can be supported by knee sub-airbags 21 that are farther away from the head area 1d, while shorter users can be supported by knee sub-airbags 21 that are closer to the head area 1d. Alternatively, if there is a deviation between the user's position and the preset sleeping position, the user's knee can be supported by knee sub-airbags 21 corresponding to the user's knee position. For example, if the user's position is closer to the head region 1d, support can be provided by the knee sub-airbag 21, which is closer to the head region 1d; if the user's position is closer to the leg region 1c, support can be provided by the knee sub-airbag 21, which is farther from the head region 1d. The knee sub-airbag 21 closer to the user's knee can be controlled to have a higher support height, thus forming a mountain-shaped support structure to conform to the user's elevated knee position.

[0054] In some embodiments, please refer to Figure 2 The knee region 1a extends into the trunk region 1b, meaning that part of the knee airbag assembly 2 is located within the trunk region 1b.

[0055] In some embodiments, please refer to Figure 2 and Figure 3 At least two knee airbag assemblies 2 are spaced apart along the width of the mattress base 1. It is understood that the width of the mattress base 1 is perpendicular to its length, and when two users are lying flat in a preset sleeping position, the distance between them is along the width of the mattress base 1. By providing at least two knee airbag assemblies 2 spaced apart along the width of the mattress base 1, they can be used to support the knees of two or more users, allowing each user to receive knee support according to their needs. Optionally, the mattress 100 includes two knee airbag assemblies 2.

[0056] In some embodiments, please refer to Figure 1 and Figure 2 The mattress 100 also includes a mattress body 4, which is positioned above the mattress base 1 and covers the knee airbag assembly 2. The knee airbag assembly 2 has a relatively high firmness when inflated, resulting in a poor user experience due to direct contact with the user. The mattress body 4 is designed to address this issue of poor user experience caused by direct contact with the knee airbag assembly 2. The mattress body 4 is made of a soft material, such as sponge or fabric.

[0057] In some embodiments, please refer to Figure 6 The mattress 100 also includes a sensor group 5, which is disposed within the mattress body 4 and electrically connected to the air source assembly 3. The sensor group 5 is used to detect the pressure distribution of the mattress body 4. Exemplarily, the sensor group 5 is layered, and the mattress body 4 includes a third layer 41 and a fourth layer 42. The sensor group 5 is sandwiched between the third layer 41 and the fourth layer 42. The sensor group 5 has multiple pressure sensors distributed on it, thereby collecting pressure data of the mattress body 4 to determine the user's sleeping posture. The air source assembly 3 can determine the position of the user's knees based on the user's sleeping posture.

[0058] In some embodiments, please refer to Figure 6 The pad 4 also includes a cover 43, which covers the third layer 41 and the fourth layer 42. The cover 43 is used to enclose the third layer 41 and the fourth layer 42 into a whole, and the cover 43 can be made of a waterproof and dustproof material to enhance the waterproof and dustproof properties of the pad 4. Alternatively, the cover 43 can be made of a breathable and dustproof material, that is, the cover 43 has micropores to allow air to pass through, but can block larger dust particles.

[0059] In some embodiments, please refer to Figure 2 and Figure 3 The mattress 100 also includes a torso airbag assembly 6, which is located in the torso area 1b. An air source assembly 3 is fluidly connected to the torso airbag assembly 6 and is used to inflate and deflate the torso airbag assembly 6. By inflating and deflating the torso airbag assembly 6, the support height of the torso airbag assembly 6 for the user's torso can be adjusted, improving the user experience of the mattress 100. Optionally, the mattress base 1 has a torso airbag recess 11, and the torso airbag assembly 6 is installed within the torso airbag recess 11.

[0060] In some embodiments, please refer to Figure 3 The torso airbag assembly 6 includes multiple torso sub-airbags 61, arranged sequentially along the length of the mattress base 1. It is understandable that when the torso airbag assembly 6 includes only one large airbag, the inflated height of the torso airbag assembly 6 is relatively high, and the top is curved, resulting in a small contact area with the user's torso and excessive support height, leading to a poor user experience. Reducing the inflation volume of the torso airbag assembly 6 can lower its inflated height and increase the contact area with the user, but this results in insufficient support and a poor user experience. By using multiple torso sub-airbags 61, the top of the inflated torso airbag assembly 6 forms a supporting plane, and the inflated height of each individual torso sub-airbag 61 is reduced, thus lowering the overall height of the inflated torso airbag assembly 6. This increases the contact area with the user's torso and reduces the support height, improving the user experience. Optionally, the torso airbag assembly 6 includes ten torso sub-airbags 61.

[0061] In some embodiments, multiple torso sub-airbags 61 are fluidly connected to the air source assembly 3, which independently controls the inflation and deflation of each torso sub-airbag 61. By independently controlling the inflation and deflation of each torso sub-airbag 61, the torso airbag assembly 6 can form different support surfaces according to the user's needs, improving the user experience. By independently controlling the inflation and deflation of each torso sub-airbag 61, the torso airbag assembly 6 can support or massage corresponding positions of the torso according to the user's needs.

[0062] In some embodiments, please refer to Figure 2 At least two torso airbag assemblies 6 are spaced apart along the width of the mattress base 1. By providing at least two torso airbag assemblies 6 spaced apart along the width of the mattress base 1, they can be used to support the torso of two or more users, allowing each user to receive torso support according to their own needs. Optionally, the mattress 100 includes two torso airbag assemblies 6.

[0063] In some embodiments, please refer to Figure 2 and Figure 3 The mattress 100 also includes a leg airbag assembly 7, which is located in the leg area 1c. An air source assembly 3 is fluidly connected to the leg airbag assembly 7 and is used to inflate and deflate the leg airbag assembly 7. By inflating and deflating the leg airbag assembly 7, the support height of the leg airbag assembly 7 for the user's legs can be adjusted, improving the user experience of the mattress 100. Optionally, the mattress base 1 has a leg airbag recess 12, and the leg airbag assembly 7 is installed within the leg airbag recess 12.

[0064] In some embodiments, please refer to Figure 3 The leg airbag assembly 7 includes multiple leg sub-airbags 71, arranged sequentially along the length of the mattress base 1. It is understandable that when the leg airbag assembly 7 includes only one large airbag, the inflated leg airbag assembly 7 is quite tall, and its top is curved, resulting in a small contact area with the user's legs and excessive support height, leading to a poor user experience. Reducing the inflation volume of the leg airbag assembly 7 can lower its inflated height and increase the contact area with the user, but this results in insufficient support and a poor user experience. By using multiple leg sub-airbags 71, the top of the inflated leg airbag assembly 7 forms a supporting plane, and the inflated height of each individual leg sub-airbag 71 is reduced, thus lowering the overall height of the inflated leg airbag assembly 7. This increases the contact area with the user's legs and reduces the support height, improving the user experience. Optionally, the leg airbag assembly 7 includes two leg sub-airbags 71.

[0065] The knee airbag assembly 2 can be deflated to a thin layer. When the user needs to elevate their knee, the knee airbag assembly 2 can be inflated to elevate the knee; when the user is lying on their side, supine, or does not need to elevate their knee, the knee airbag assembly 2 can be deflated to a thin layer, without affecting the supine or flat position of the mattress 100. Furthermore, when the knee airbag assembly 2 is deflated to a thin layer, it does not affect the use of the leg airbag assembly 7.

[0066] In some embodiments, multiple leg sub-airbags 71 are all in fluid communication with the air source assembly 3, which independently controls the inflation and deflation of each leg sub-airbag 71. By independently controlling the inflation and deflation of each leg sub-airbag 71, the leg airbag assembly 7 can form different support surfaces according to the user's needs, improving the user experience. By independently controlling the inflation and deflation of each leg sub-airbag 71, the leg airbag assembly 7 can support corresponding positions of the leg according to the user's needs, or massage corresponding positions of the leg according to the user's needs.

[0067] In some embodiments, please refer to Figure 2 At least two leg airbag assemblies 7 are spaced apart along the width of the mattress base 1. By providing at least two leg airbag assemblies 7 spaced apart along the width of the mattress base 1, they can be used to support the legs of two or more users, allowing each user to receive leg support according to their own needs. Optionally, the mattress 100 includes two leg airbag assemblies 7.

[0068] In some embodiments, please refer to Figure 2 and Figure 3 The mattress 100 also includes a head airbag assembly 8, which is located in the head area 1d. An air source assembly 3 is fluidly connected to the head airbag assembly 8 and is used to inflate and deflate the head airbag assembly 8. By inflating and deflating the head airbag assembly 8, the support height of the head airbag assembly 8 for the user's head can be adjusted, improving the user experience of the mattress 100. Optionally, the mattress base 1 has a head airbag recess 13, and the head airbag assembly 8 is installed within the head airbag recess 13.

[0069] In some embodiments, please refer to Figure 2 At least two head airbag assemblies 8 are spaced apart along the width of the mattress base 1. By providing at least two head airbag assemblies 8 spaced apart along the width of the mattress base 1, they can be used to support the heads of two or more users, allowing each user to provide head support according to their own needs. Optionally, the mattress 100 includes two head airbag assemblies 8.

[0070] In some embodiments, please refer to Figure 3The head airbag assembly 8 includes a head sub-airbag 81 and a head support pad 82. The head sub-airbag 81 is located below the head support pad 82 and is used to drive the head support pad 82 to move up and down. When the head airbag assembly 8 is fully inflated, it has a high degree of rigidity, resulting in a poor user experience due to direct contact with the user; when the head airbag assembly 8 is underinflated, it has a low degree of rigidity and insufficient support. The head support pad 82 is used to contact the user, improving the problem of poor user experience caused by direct contact with the head airbag assembly 8. The head airbag assembly 8 is made of a soft material, such as sponge or fabric. Optionally, multiple head sub-airbags 81 are arranged at the bottom of the head support pad 82 to enhance the stability of the support for the head support pad 82.

[0071] In some embodiments, the cushion 4 also covers at least one of the torso airbag assembly 6, the leg airbag assembly 7, and the head airbag assembly 8. This improves the poor user experience caused by direct contact with the torso airbag assembly 6, the leg airbag assembly 7, and the head airbag assembly 8.

[0072] In some embodiments, please refer to Figure 1 and Figure 2 The mattress 100 also includes a mattress cover 9, which is placed over the mattress base 1 and covers the knee airbag assembly 2, torso airbag assembly 6, leg airbag assembly 7, and head airbag assembly 8. The mattress cover 9 encloses the mattress base 1, knee airbag assembly 2, torso airbag assembly 6, leg airbag assembly 7, and head airbag assembly 8 as a whole, and the mattress cover 9 may be made of waterproof and dustproof material to enhance the waterproof and dustproof properties of the mattress 100. The mattress body 4 is positioned above the mattress cover 9 for easy replacement and washing; alternatively, the mattress body 4 may also be enclosed within the mattress cover 9.
