Description

Technical Field

[0001] This application relates to the field of sleep aids technology, and in particular to an adaptive adjustable pillow and an adaptive adjustment method. Background Technology

[0002] Traditional self-adjusting pillows mainly come in two types: one uses foam material for the pillow core, utilizing the elastic deformation properties of the foam to achieve passive support; the other has air bladders inside the pillow core, achieving active adjustment through the active inflation and deflation of the air bladders. However, both types of self-adjusting pillows have relatively poor adaptability and are difficult to accommodate individual differences and sleeping postures among different users. Summary of the Invention

[0003] Therefore, it is necessary to provide an adaptive adjustable pillow to improve its adaptability and accommodate individual differences and sleeping posture differences.

[0004] This application provides an adaptive adjustable pillow, including a pillow body and a support structure disposed inside the pillow body. Multiple support structures are arranged along the extension direction of the pillow surface of the pillow body. Each support structure includes a sensor, a power component, and a support member. The sensor is disposed below the pillow surface and is used to detect the pressure on the corresponding pillow surface. The power component is electrically connected to the sensor to control the action of its power output end based on the pressure signal detected by the sensor. Each power component in each support structure is independently controlled. The support member is drivenly connected to the power output end of the power component and moves up and down under the drive of the power component. The support member is located below the corresponding sensor.

[0006] In one embodiment, the support area includes a central area and an edge transition area. The edge transition area includes a left edge transition area and a right edge transition area. The left edge transition area is located to the left of the central area along the length direction of the pillow body, and the right edge transition area is located to the right of the central area along the length direction of the pillow body.

Each of the headrest area, the cervical spine support area, the left sleeping support area, and the right sleeping support area is provided with at least one of the support structures.

[0007] In one embodiment, the arrangement density of the support structure in the headrest area is greater than the arrangement density of the support structure in the edge transition area; and / or, the arrangement density of the support structure in the cervical spine support area is greater than the arrangement density of the support structure in the edge transition area.

[0008] In one embodiment, the support structure is provided in 8 to 20 units.

[0009] In one embodiment, eleven support structures are provided, each consisting of two edge support structures and nine center support structures. The two edge support structures are spaced apart along the length of the pillow body. Along the length of the pillow body, the nine center support structures are located between the two edge support structures, and the nine center support structures are arranged in a rectangular distribution of three rows and three columns, with the row and column extension directions of the rectangular distribution parallel to the length and width directions of the pillow body, respectively.

[0010] In one embodiment, along the thickness direction of the pillow body, an elastic layer is provided between the support member and the sensor. The elastic layer includes a support layer, a buffer layer and an adhesive layer arranged sequentially from bottom to top. The hardness of the buffer layer is less than that of the support layer and greater than that of the adhesive layer.

[0014] S1: The sensor completes zero-point calibration and parameter initialization, and the support structure is reset to the reference position;

[0015] S2: The sensor collects pressure data in real time;

[0016] S3: Based on the pressure data collected by the sensor, the corresponding power component drives the support to move up and down until the distance the support moves up and down matches the pressure data collected by the sensor.

[0035] Please see Figures 1 to 9This application provides an adaptive adjustable pillow for improving a user's sleep quality. Specifically, the adaptive adjustable pillow can adaptively adjust its support for the user's head and cervical spine according to individual differences and sleeping posture. The adaptive adjustable pillow includes a pillow body 10 and support structures 11 disposed inside the pillow body 10. Multiple support structures 11 are provided and arranged along the extension direction of the pillow surface 13 of the pillow body 10, thereby supporting multiple parts of the pillow surface 13 through the support structures 11 to meet more support needs.

[0036] Each support structure 11 includes a sensor 12, a power assembly 14, and a support member 15. The sensor 12 is located below the pillow surface 13 and is used to detect the pressure on the corresponding pillow surface 13. Specifically, the sensor 12 is used to detect the pressure on a certain area of ​​the pillow surface 13, and this area corresponds to the sensor 12. This arrangement prevents the sensor 12 from being exposed from the pillow surface 13, thereby avoiding direct contact between the user's head and neck and the sensor 12, improving aesthetics and user comfort.

[0037] The power assembly 14 is electrically connected to the sensor 12, enabling the power assembly 14 to control the action of the power output end based on the pressure signal detected by the sensor 12. Each power assembly 14 in each support structure 11 is independently controlled; that is, the power assembly 14 in the same support structure 11 controls its operation based on the detection results of the sensor 12 in the same support structure 11. The supporting function of each support structure 11 is not the same, achieving multi-point and differentiated support adjustment of the pillow surface 13. Furthermore, the connection between the power assembly 14 and the sensor 12 can be wired or wireless; this application does not limit this connection.

[0038] The support member 15 is driven and connected to the power output end of the power assembly 14, and moves up and down under the drive of the power assembly 14. The support member 15 is located below the corresponding sensor 12. The function of the support member 15 is to support the pillow surface 13. Generally, the support member 15 needs to be made of high-strength materials or structures to prevent deformation of the support member 15 when supporting the pillow surface 13, which would affect the support effect. The power assembly 14 drives the support member 15 to realize the up and down movement of the support member 15. That is, the power assembly 14 adopts a linear drive component, such as an electric push rod, a lifting screw, or a linear electrode, etc., as long as it can drive the support member 15 to move up and down. This application does not limit the specific structure of the power assembly 14.

[0039] When a portion of the pillow surface 13 is compressed, the sensors 12 on that portion detect the pressure in their respective areas and feed the results back to the corresponding power components 14. Based on the detection results, the power components 14 drive the corresponding support members 15 to rise, thereby supporting the pillow surface 13 and applying pressure to the user's head and cervical spine. Generally, the greater the pressure on the area of ​​the pillow surface 13, the greater the pressure detected by the sensors 12, and the greater the distance the power components 14 drive the support members 15 to rise, thus providing a greater supporting force to the pillow surface 13. The specific correspondence between the pressure detected by the sensors 12 and the distance the power components 14 drive the support members 15 to rise is not specifically limited in this application.

[0040] In some embodiments of this application, a control module (not shown) is also included. Each power component 14 is provided with a control module, and the power component 14 is electrically connected to the corresponding sensor 12 through its respective control module. After receiving the pressure data collected by the sensor 12, the control module controls the distance by which the corresponding power component 14 drives the support member 15 to rise.

[0041] In some other embodiments of this application, the control module is electrically connected to all the sensors 12 and the power components 14. That is, an integrated control module is used to receive and process the data collected by the sensors 12 and to control all the power components 14. Of course, the distance that each power component 14 drives the support 15 to rise is still based on the pressure data collected by the corresponding sensor 12.

[0042] Please participate Figure 3 and Figure 9 In some embodiments of this application, the pillow body 10 has a cavity 37 for accommodating the mounting shell 32. The mounting shell 32 includes a detachably connected bottom shell 33 and a top shell 34. The bottom shell 33 and the top shell 34 are connected and form an inner cavity 36. The support structures 11 are all built into the inner cavity 36, providing protection for the support structures 11. In addition, the top shell 34 has a through hole 35 running vertically through it, allowing the support member 15 to enter and exit the inner cavity 36. After the support member 15 moves upward and moves out of the inner cavity 36 through the through hole 35, it can provide support for the pillow surface 13.

[0043] For example, please refer to Figure 1The pillow body 10 is a flat hexahedron with dimensions of 70cm × 40cm × 10cm. The upper surface of the pillow body 10 is the pillow surface 13, which comes into contact with the user's head and neck. The pillow body 10 is typically made of flexible materials, such as memory foam, latex, or polyurethane foam, to provide basic elastic support for the user's head and neck and ensure comfort. The pillow body 10 has an internal cavity 37, which is adapted to the shape of the mounting shell 32, which has dimensions of 30cm × 19cm × 7cm. Of course, in other embodiments, the dimensions of the pillow body 10 and the mounting shell 32 can be adjusted as needed, and this application does not limit them.

[0044] In some embodiments of this application, the pillow body 10 has a support region 16 and a non-load-bearing region 17 located around the support region 16, with multiple support structures 11 spaced apart within the support region 16. It is understood that when the user uses the pillow, their head and neck primarily rest on the support region 16; therefore, the support structures 11 are mainly provided in the support region 16, while the non-load-bearing region 17, i.e., the outer peripheral edge area of ​​the pillow body 10, may not have support structures 11, achieving a certain cost-saving effect.

[0045] At least two support structures 11 are arranged at intervals along the length of the pillow body 10. The ratio of the center distance between two adjacent support structures 11 along the length of the pillow body 10 to the length of the support area 16 along the length of the pillow body 10 is k1, where 1 / 6 ≤ k1 ≤ 1 / 4; and / or, at least two support structures 11 are arranged at intervals along the width of the pillow body 10. The ratio of the center distance between two adjacent support structures 11 along the width of the pillow body 10 to the length of the support area 16 along the width of the pillow body 10 is k2, where 1 / 8 ≤ k2 ≤ 1 / 5. Specifically, when multiple support structures 11 in the support area 16 are arranged linearly only along the length of the pillow body 10, the arrangement condition of "1 / 6 ≤ k1 ≤ 1 / 4" for the support structures 11 must be satisfied; when multiple support structures 11 in the support area 16 are arranged linearly only along the width of the pillow body 10, the arrangement condition of "1 / 8 ≤ k2 ≤ 1 / 5" for the support structures 11 must be satisfied. Preferably, the multiple support structures 11 provided in the support area 16 are arranged in a rectangular array. In this case, the arrangement conditions of the support structures 11 must be met simultaneously: "1 / 6≤k1≤1 / 4" and "1 / 8≤k2≤1 / 5". This way, the center distance between adjacent support structures 11 is more appropriate, which can provide users with a general distributed support function and avoid blind spots that fail to provide effective support due to excessive spacing. At the same time, the arrangement of the support structures 11 will not be too dense, which will increase production costs.

[0046] For more specific details, please see Figure 2 and Figure 3Let d1 be the center-to-center distance of the support structure 11 along the length of the pillow body 10, d2 be the center-to-center distance of the support structure 11 along the width of the pillow body 10, L be the length of the support area 16 along the length of the pillow body 10, and W be the length of the support area 16 along the width of the pillow body 10. Then, the ratio of the center-to-center distance of the support structure 11 along the length of the pillow body 10 to the length of the support area 16 along the length of the pillow body 10 is 1 / 6 ≤ (k1 = d1 / L) ≤ 1 / 4; the ratio of the center-to-center distance of the support structure 11 along the width of the pillow body 10 to the length of the support area 16 along the width of the pillow body 10 is 1 / 8 ≤ (k2 = d2 / W) ≤ 1 / 5.

[0047] Please combine Figure 4 In a further embodiment of this application, the support area 16 includes a central area 18 and an edge transition area 19. The edge transition area 19 includes a left edge transition area 20 and a right edge transition area 21. The left edge transition area 20 is located to the left of the central area 18 along the length of the pillow body 10, and the right edge transition area 21 is located to the right of the central area 18 along the length of the pillow body 10. Both the left edge transition area 20 and the right edge transition area 21 are provided with at least one support structure 11. The provision of support structures 11 in the edge transition area 19 enables a smooth transition from the central area 18 to the edge of the pillow body 10, preventing the edge of the pillow body 10 from being too hard or too soft, and improving the user experience.

[0048] The central area 18 includes a headrest area 22, a cervical spine support area 23, a left sleeping support area 24, and a right sleeping support area 25. The headrest area 22 and the cervical spine support area 23 are arranged along the width direction of the pillow body 10. The left sleeping support area 24 is located on the left side of the headrest area 22 and the cervical spine support area 23 along the length direction of the pillow body 10. The right sleeping support area 25 is located on the right side of the headrest area 22 and the cervical spine support area 23 along the length direction of the pillow body 10. Each of the headrest area 22, the cervical spine support area 23, the left sleeping support area 24, and the right sleeping support area 25 is provided with at least one support structure 11. Understandably, the support structure 11 in the headrest area 22 is mainly used to support the user's head, the support structure 11 in the cervical spine support area 23 is mainly used to support the user's cervical spine, the support structure 11 in the left side sleeping support area 24 is mainly used to support the user's head and cervical spine when turning to the left for side sleeping, and the support structure 11 in the right side sleeping support area 25 is mainly used to support the user's head and cervical spine when turning to the right for side sleeping.

[0049] It is important to note that when a user rolls over to the left or right, it refers to the user's face changing from a normal supine position to a leftward or rightward position, not to the user's left-right orientation. Specifically, the left-side sleeping support area 24 is located on the left side of the headrest area 22 and the cervical spine support area. When the user is lying normally on their back, their head and cervical spine are primarily supported by the support structures 11 in the headrest area 22 and the cervical spine support area 23. When the user rolls over to the left from their normal supine position, their head and cervical spine are primarily supported by the support structures 11 in the left-side sleeping support area 24; similarly, when the user rolls over to the right from their normal supine position, their head and cervical spine are primarily supported by the support structures 11 in the right-side sleeping support area 25.

[0050] Preferably, the arrangement density of the support structures 11 in the headrest area 22 is greater than that in the edge transition area 19, ensuring the support accuracy of the headrest area 22 while reducing the overall support complexity. Similarly, the arrangement density of the support structures 11 in the cervical spine support area 23 can also be set to be greater than that in the edge transition area 19, ensuring the support accuracy of the cervical spine support area 23 while reducing the overall support complexity. For example, the arrangement density of the support structures 11 in the headrest area 22 refers to the ratio of the number of support structures 11 provided in the headrest area 22 to the area of ​​the headrest area 22 in a top-down view.

[0051] In one specific embodiment of this application, the support structure 11 is provided with 8 to 20 supports to meet or substantially meet the support requirements of the pillow surface 13.

[0052] Please combine Figures 5 to 8 Furthermore, eleven support structures 11 are provided, each consisting of two edge support structures 26 and nine central support structures 27. The two edge support structures 26 are arranged at intervals along the length of the pillow body 10. Along the length of the pillow body 10, the nine central support structures 27 are all located between the two edge support structures 26. The nine central support structures 27 are arranged in a rectangular distribution of three rows and three columns, and the row and column extension directions of the rectangular distribution are parallel to the length and width directions of the pillow body 10, respectively.

[0053] For more details, please see Figure 5 The two edge support structures 26 are support structures 11 located in the left edge transition area 20 and the right edge transition area 21, respectively, and the nine center support structures 27 are support structures 11 located in the center area 18.

[0054] Further, please see Figure 6 and Figure 7Of the nine central support structures 27, the six central support structures 27 in the top two rows are located in the headrest area 22, and the six central support structures 27 in the bottom two rows are located in the cervical spine support area 23. It can be understood that the three central support structures 27 in the middle row can support both the user's head and cervical spine.

[0055] In addition, when the user is sleeping on their side, the support structure 11 can also support the user's ears and shoulders, improving the user's comfort when sleeping on their side.

[0056] Please continue reading Figure 8 Of the nine central support structures 27, the three central support structures 27 in the left column are located in the left sleeping support area 24, and the three central support structures 27 in the right column are located in the right sleeping support area 25. It can be understood that the central support structures 27 in the middle of the left column and the middle of the right column can support the user's head and cervical spine when the user is lying normally on their back, and also when the user is lying on their side.

[0057] Specifically, in this embodiment, the headrest area 22 and the cervical spine support area 23 partially overlap, and a support structure 11 is provided in the overlapping portion, which can support both the user's head and the user's cervical spine. The non-overlapping portions of the headrest area 22 and the cervical spine support area 23 are also provided with support structures 11. The support structure 11 in the non-overlapping portion of the headrest area 22 is used to support the user's head, and the non-overlapping portion of the cervical spine support area 23 is used to support the user's cervical spine.

[0058] Additionally, taking the left-side sleeping support area 24 as an example, the left-side sleeping support area 24 and the headrest area 22 partially overlap, and a support structure 11 is provided in the overlapping part, which can support the user's head both when the user is lying normally on their back and when the user turns to their left side to sleep. The left-side sleeping support area 24 and the cervical spine support area 23 partially overlap, and a support structure 11 is provided in the overlapping part, which can support the user's cervical spine both when the user is lying normally on their back and when the user turns to their left side to sleep.

[0059] In some embodiments of this application, the right sleeping support area 25 and the left sleeping support area 24 may be arranged symmetrically about the center of the central area 18, which will not be elaborated further in this application.

[0060] The overlapping arrangement of different areas is designed to meet the individual differences in head and neck support among different users.

[0061] Please see Figure 9In some embodiments of this application, an elastic layer 28 is provided between the support member 15 and the sensor 12 along the thickness direction of the pillow body 10. The elastic layer 28 includes a support layer 29, a buffer layer 30, and an adhesive layer 31 arranged sequentially from bottom to top. The hardness of the buffer layer 30 is less than that of the support layer 29, and the hardness of the buffer layer 30 is greater than that of the adhesive layer 31. Specifically, the hardness of the support layer 29, the buffer layer 30, and the adhesive layer 31 decreases sequentially.

[0062] Relatively speaking, the support layer 29 is the hardest, requiring relatively rigid contact with the support member 15 to stably transmit the upward supporting force of the support member 15 to the pillow surface 13. The buffer layer 30 has moderate hardness, offsetting local stress and preventing hard spots in the support. The bonding layer 31 is the softest, better conforming to the curve of the user's head and neck, improving comfort.

[0063] In some embodiments of this application, the center of the support member 15 coincides with the center of the corresponding sensor 12 on the thickness direction projection of the pillow body 10. In other words, the line connecting the center of the support member 15 and the center of the corresponding sensor 12, i.e., the center line 38, extends in a direction parallel to the vertical direction, avoiding the impact of eccentricity on the support effect of the support member 15, and further improving the support accuracy and stability of the support point.

[0064] In some preferred embodiments of this application, the sensor 12 is a thin-film resistive pressure sensor, which is thin and flexible, allowing it to fit better against the inner side of the pillow surface 13 and avoid affecting the user's comfort. Furthermore, the thin-film resistive pressure sensor has high sensitivity, ensuring the real-time and accurate detection of pressure data. In one preferred embodiment, certain requirements are placed on one or more performance characteristics of the sensor 12, such as a frequency ≥100Hz, a measurement accuracy of ±2%FS, and a resolution of 0.25N. These parameter requirements ensure the reliability of the detection results of pressure changes on the pillow surface 13.

[0065] This application also provides an adaptive adjustment method for an adaptive adjustment pillow as described in any of the above embodiments, comprising the following steps:

[0066] S1: Sensor 12 completes zero-point calibration and parameter initialization, and support structure 11 is reset to the reference position;

[0067] S2: Sensor 12 collects pressure data in real time;

[0068] S3: Based on the pressure data collected by sensor 12, the corresponding power component 14 drives the support 15 to move up and down until the distance of the support 15 moving up and down matches the pressure data collected by sensor 12.

[0069] In addition, the control module can also set multiple modes for users to choose from. Specifically, in different modes (such as follow-up mode / anti-snoring mode / neck traction / dowager's hump improvement / deep sleep / sleep aid mode, etc.), when the data collected by the sensor 12 is the same, the distance by which the control module controls the power component 14 to drive the support member 15 to rise is also different, so that the supporting effect of the support member 15 matches the requirements of the corresponding mode.

[0070] Specifically, the adaptive adjustable pillow can also be equipped with other auxiliary data acquisition devices (not shown in the figure), which can be used to acquire environmental data such as human physiological signals and noise (snoring) signals. These data are also uploaded to the control module along with the pressure data. The control module can adjust the distance of the rise of the support member 15 by the adaptive control power component 14 based on these auxiliary data to improve the user's sleep comfort.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
