Description

Technical Field

[0001] The present disclosure relates to the field of smart home, and more specifically, to bedding with a sleeping posture detection mechanism. Background Art

[0002] In recent years, in the field of health care, it is well known that sleep has become the third most important factor affecting health after diet and exercise. Especially for people with sub-health caused by high mental stress, bad work and rest habits, long-term incorrect posture, etc., which are common in modern society, there is an urgent need to effectively relieve stress, eliminate fatigue, and even adjust body posture during the sleep time that occupies about 1 / 3 of life. Therefore, people pay more and more attention to sleep quality year by year. In the field of smart home, with the rapid intelligence of pillows, mattresses and other bedding involved in the sleep industry, whether in specific professional institutions such as medical care or elderly care, or as daily necessities for ordinary residents, the requirements for helping to eliminate sleep disorders caused by various factors and improving the sleep quality of sub-healthy people are increasing day by day, so a variety of smart pillows, smart mattresses and other smart bedding are emerging in an endless stream.

[0003] The human body is in a quasi-static state during sleep, but maintaining a specific static posture for a long time will cause poor local blood circulation in the human body, and the brain will immediately issue a command to turn over to improve discomfort. Medical research has found that normal people adjust their sleeping postures about every half an hour during sleep. In order to realize the adaptive adjustment function, which is the core function of smart bedding, real-time and accurate detection of various sleeping postures including side sleeping and supine sleeping is of great significance for the automatic adjustment of the shape of smart bedding, as well as various automatic intervention functions including anti-snoring.

[0004] Among the existing sleeping posture detection technologies, judgment based on torso angle detection and recognition based on human body pressure distribution are common. In the case of detecting the torso angle, it is necessary to set an element for angle detection on the human body, which cannot achieve the requirements of naturalness and non-sensing, greatly reduces the user experience, and is not conducive to improving the user's sleep quality. In the detection technology based on human body pressure distribution, some need to set a large area of ​​pressure sensor matrix on bedding such as mattresses or pillows, resulting in high costs and poor product integrity; some need to set a detection belt on the edge of bedding such as pillows, which not only increases the cost, but also easily causes a foreign body sensation in the part that is close to the human body, and at the same time causes the shape of bedding such as pillows to change. In this regard, the industry is in urgent need of improved bedding with sleeping posture detection mechanism that can simultaneously achieve high sleeping posture detection accuracy, low cost and user-friendliness. Summary of the invention

[0005] In response to the above-mentioned problems of the existing sleeping posture detection technology, researchers in this field have conducted in-depth research and development and proposed bedding with a sleeping posture detection mechanism that can use air pressure detection to determine sleeping posture.

[0006] The utility model provides a bedding with a sleeping position detection mechanism, which may include: a sleeping position detection airbag, which is arranged in a sheet shape and parallel to the ground, and whose short side has a width that can cover the user's head to the neck, and the sleeping position detection airbag can support the gravity applied by the user's head; a barometer, which is connected to the sleeping position detection airbag, detects the air pressure of the sleeping position detection airbag, and is configured separately from the sleeping position detection airbag when viewed from above; and a controller, which is connected to the barometer and the height adjustment mechanism, drives the height adjustment mechanism to change the height according to the detection result of the barometer, and is configured separately from the sleeping position detection airbag when viewed from above.

[0007] By adopting the bedding with the above structure, the sleeping posture of the user can be accurately detected at a relatively low cost, while improving the user's comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the components, etc. described in these embodiments do not limit the scope of the present invention. At the same time, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The following description of at least one exemplary embodiment is actually only illustrative and is not intended to be any limitation to the present invention and its application or use.

[0023] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0024] For ease of understanding and explanation, the bedding with a sleeping posture detection mechanism according to the embodiment of the utility model is mainly described by taking a pillow and a mattress as an example, but this is not restrictive. Those skilled in the art can understand that the technical purpose of the utility model can be applied not only to any currently known suitable bedding, but also to any suitable bedding in the future.

[0025] Below, first briefly introduce the principle of the sleeping posture detection technology of the present invention. When the human body is in supine and side lying, the unit area pressure (i.e., pressure) of the head on bedding such as pillows or mattresses is different. For convenience, the pillow is mainly used as an example of bedding for explanation below, but this is non-restrictive. The pressure of a person's head on bedding such as a pillow when lying on his back is greater than the pressure when lying on his side. Based on this, it can be considered to set a detection airbag inside bedding such as a pillow, and judge the sleeping posture of the human body according to the air pressure value and / or air pressure change of the detection airbag.

[0026] Next, refer to Figure 1 , the overall structure of the bedding with a sleeping posture detection mechanism according to an embodiment of the utility model is described. Figure 1 The present invention is an exemplary schematic diagram of a bedding with a sleeping posture detection mechanism according to an embodiment of the present invention, wherein, from top to bottom, (a) shows a schematic perspective view of the overall structure of a pillow 100 as a bedding, (b) shows a schematic top view of the pillow 100, (c) shows a schematic side view of the shape of the pillow 100 when the user is lying on his back, and (d) shows a schematic side view of the shape of the pillow 100 when the user is lying on his side.

[0027] Reference Figure 1 The bedding with a sleeping position detection mechanism of an embodiment of the utility model may include: a sleeping position detection airbag 1, which is arranged in a sheet shape and parallel to the ground, and its short side has a width that can cover the user's head to the neck, and the sleeping position detection airbag 1 can support the gravity applied by the user's head; a barometer 4, connected to the sleeping position detection airbag 1, detects the air pressure of the sleeping position detection airbag 1, and is configured separately from the sleeping position detection airbag 1 when viewed from above; and a controller 3, connected to the barometer 4 and a height adjustment mechanism not shown in the figure, drives the height adjustment mechanism to change the height according to the detection result of the barometer 4, and is configured separately from the sleeping position detection airbag 2 when viewed from above.

[0028] More specifically, the barometer 4 can be connected to the sleeping position detection airbag 1 through, for example, the trachea 5 to detect the air pressure of the sleeping position detection airbag 1. When the user leaves the pillow, the air pressure of the sleeping position detection airbag 1 is the lowest, which is the initial air pressure, and can be 1~10kPa, preferably, for example, about 2.5kPa. When the human body is in a supine position relative to the bedding as a pillow, the pressure of the head on the pillow is greater than the pressure when lying on the side. At this time, the air pressure of the sleeping position detection airbag 1 is also relatively large, and the value range is, for example, 2~10kPa, specifically, about 5kPa; when the human body is in a side-lying position, the value range of the air pressure of the sleeping position detection airbag 1 is, for example, 2~10kPa, specifically, about 4.5kPa. During use, the controller 3 connected to the barometer 4 determines the sleeping position of the human body based on the detection result from the barometer 4, based on the air pressure range of the air pressure value of the detection result, and / or based on the direction of the large change in the detection result from the barometer 4. For example, when the human body turns from lying on the side to lying on the back, the air pressure value sensed by the barometer 4 will increase by, for example, 50-800 Pa, specifically, by about 500 Pa; when the human body turns from lying on the back to lying on the side, the air pressure value sensed will decrease by, for example, 50-800 Pa, specifically, by about 500 Pa. According to the direction (increase / decrease) of the significant change in the detection result of the barometer 4, the controller 3 can also determine and update the sleeping posture of the human body in real time to perform further control processing.

[0029] The controller 3 may include a memory and a processor coupled to the memory, and determines the user's sleeping position according to the air pressure detection result from the barometer 4, and inflates / deflates the airbag through the trachea 5 to change the height of the bedding. Those skilled in the art will understand that the air pressure values ​​exemplified above are only examples, and the data of each user lying on their back / side can be collected by, for example, an artificial intelligence AI algorithm to train a model, and obtain more accurate real-time sleeping position determination results for different users, which will not be elaborated here.

[0030] Figure 2 An exemplary schematic diagram of a sleeping position detection airbag 1 according to an embodiment of the utility model is shown, wherein (a) to (c) show schematic oblique views, top views and side views in sequence. Preferably, the sleeping position detection airbag 1 is provided with one or more parallel pressure strips, through which the upper and lower surfaces of the airbag 1 are connected to divide the airbag surface into a plurality of connected sub-areas. For convenience, the figure shows an example in which four parallel pressure strips are arranged in the middle of the sleeping position detection airbag 1 to divide the airbag 1 into five connected sub-areas. However, the number of the pressure strips can be changed according to actual conditions, as long as there are more than one. In addition, the figure shows a situation in which both ends of the pressure strips are not connected to the edge of the airbag, but it can also be set to a structure in which one end of more than one pressure strip is connected to the edge of the airbag 1 according to actual conditions. As long as it can ensure that the sleeping position detection airbag 1 remains uniform and flat when inflated, any suitable structure can be adopted, which will not be repeated here.

[0031] Return to Figure 1 , see e.g. Figure 1 (b) to (d), regarding the size of the sleeping position detection airbag 1, it is preferably set to be within the range covered by the sleeping position detection airbag 1 when viewed from above, and the barometer 4 and the controller 3 are located outside the range covered by the sleeping position detection airbag 1.

[0032] The following Figure 3~Figure 10 Both show exemplary schematic diagrams of bedding with a sleeping posture detection mechanism according to an embodiment of the utility model, and respectively show different structures formed by various combinations of the sleeping posture detection airbag 1 and the height adjustment mechanism 2 .

[0033] According to the embodiment of the utility model, the bedding with a sleeping position detection mechanism may also include: a height adjustment mechanism 2, which is arranged to overlap with the sleeping position detection airbag 1 when viewed from above, and is adjusted in height according to the control of the controller 3 in a manner that the height when the user is in a side-lying state is higher than the height when the user is in a supine state. This is because, from the perspective of human physiology, especially the perspective of neck health, the human body has different requirements for pillow height when lying on the back and on the side. When lying on the back, the pillow height is usually required to be, for example, less than 8 cm (based on the highest point of the neck), while when lying on the side, the pillow height is usually required to be, for example, more than 11 cm. The height adjustment mechanism is used to dynamically adjust the height of the pillow to adapt to different sleeping positions of the human body.

[0034] As the height adjustment mechanism 2, various forms can be adopted. Specifically, for example, the sleeping posture detection airbag 1 can be used as the height adjustment mechanism 2. For example, Figure 3 is an exemplary schematic diagram of a bedding with a sleeping posture detection mechanism according to an embodiment of the present utility model, and Figure 1 Similarly, from top to bottom, (a) to (d) sequentially show a perspective view, a top view, a side view when the user lies on his back, and a side view when the user lies on his side of the overall structure of the pillow 100. Figure 1 The difference is that the sleeping posture detection airbag 1' also serves as the height adjustment mechanism 2. At this time, the controller 3 is connected to the sleeping posture detection airbag 1' serving as the height adjustment mechanism 2 through the air tube 5, and drives the airbag 1' to change its height according to the detection result of the barometer 4, so that the airbag 1' is inflated when the user changes from a supine state to a side-lying state, and is deflated when the user changes from a side-lying state to a supine state. Therefore, compared with the prior art, it is possible to use only one airbag at a low cost and a simple process to simultaneously realize accurate detection of sleeping posture according to air pressure, and then perform ergonomic height adjustment without causing discomfort to the sleeping user.

[0035] As the height adjustment mechanism 2, a structure that is provided separately from the sleeping position detection airbag 1 can also be adopted. Preferably, the height adjustment mechanism 2 can include at least one height adjustment airbag 20 that is different from the sleeping position detection airbag 1, and the at least one height adjustment airbag 20 is located within the range covered by the sleeping position detection airbag 1 when viewed from above, and can be located above or below the sleeping position detection airbag 1 when viewed from the side; the at least one height adjustment airbag 20 is inflated when the user changes from a supine position to a side-lying position, and is deflated when the user changes from a side-lying position to a supine position; in a side view, the initial air pressure of the sleeping position detection airbag 1 when it is located above the height adjustment mechanism 2 is greater than the initial air pressure when it is located below the height adjustment mechanism 2.

[0036] Exemplarily, exemplary schematic diagrams of bedding with a sleeping posture detection mechanism according to an embodiment of the present utility model are shown respectively. Figure 4~Figure 9 middle, Figure 4 and Figure 5 and Figure 1 Similarly, (a) to (d) show the perspective view, top view, side view when the user lies on his back, and side view when the user lies on his side of the overall structure of the pillow 100 in sequence; Figure 6~Figure 9 For the sake of simplicity, the three-dimensional perspective views are omitted, wherein (a) to (c) sequentially show a top view of the pillow 100 , a side view when the user lies on his back, and a side view when the user lies on his side.

[0037] Specifically, Figure 4 and Figure 7 2 shows a case where the at least one height-adjusting airbag includes a single height-adjusting airbag 20, which is arranged in a sheet-like manner and overlaps with the sleeping position detection airbag 1 when viewed from above. When the single height-adjusting airbag 20 is used as the height adjustment mechanism 2, Figure 4 FIG. 4 shows a case where the height adjustment airbag 20 as the height adjustment mechanism 2 is located above the sleeping position detection airbag 1. Figure 7 2 shows a state in which the height adjustment airbag 20 as the height adjustment mechanism 2 is located below the sleeping position detection airbag 1 .

[0038] Regarding the sleeping posture detection airbag 1, Figure 7 The initial pressure in the structure is greater than that in Figure 4 The initial gas pressure in. This is because, compared to Figure 4 When the center is in a relatively lower position, Figure 7 When the sleeping posture detection airbag 1 is located closer to the top of the user's head, a larger initial air pressure is required to support the gravity of the head to prevent the upper and lower surfaces from being pressed together and failing to obtain an accurate air pressure measurement value.

[0039] According to include Figure 4 and Figure 7 Including Figures 4 to 9 , compared to, for example, Figure 3 In the case where the sleeping posture detection airbag 1 ′ itself serves as the height adjustment mechanism 2 , the range of height adjustment can be expanded, and the height adjustment can be performed more flexibly.

[0040] Figure 5 , 6, 8, and 9 show the case where the at least one height-adjusting airbag includes a plurality of height-adjusting airbags 20. As can be seen from the top views in each figure, the at least one height-adjusting airbag includes two or more columnar height-adjusting airbags 20, which are arranged parallel to the long side or short side direction of the sleeping position detection airbag 1 and spaced apart from each other when viewed from above. Figure 5 , 8 9 shows a situation where three height adjustment airbags 20 are arranged in parallel with the short side direction of the sleeping position detection airbag 1, and Figure 6 2 shows a case where two height-adjustable airbags 20 are arranged in parallel with the long side direction of the sleeping position detection airbag 1. The number of height-adjustable airbags 20 here is only an example, and other appropriate numbers can be used according to actual conditions. In this case, the plurality of height-adjustable airbags 20 can be located above the sleeping position detection airbag 1 when viewed from the side, for example, Figure 5 , Figure 6 As shown in FIG. 1 , it may also be located below the sleeping position detection airbag 1, for example, Figure 8 , Fig. 9 In particular, when Fig. 9 In the case where a plurality of height-adjustable airbags 20 are used as the height-adjusting mechanism 2 and the plurality of height-adjustable airbags 20 are located below the sleeping position detecting airbag 1 , the sleeping position detecting airbag 1 needs to have a hardness sufficient to support the gravity applied by the user's head.

[0041] Preferably, the height adjustment mechanism 2 may further include a pair of support plates 21 that clamp the at least one height adjustment airbag 20 from the upper and lower directions when viewed from the side, and the pair of support plates 21 overlap the sleeping position detection airbag 1 when viewed from the top. Figure 5 , Figure 6 and Figure 8 2 shows a structure in which the height adjustment mechanism 2 includes at least one height adjustment airbag 20 and a pair of support plates 21. Similarly, the height adjustment mechanism 2 including the height adjustment airbag 20 and the pair of support plates 21 can be located above the sleeping position detection airbag 1 when viewed from the side, for example, Figure 5 , Figure 6 As shown in FIG. 1 , it may also be located below the sleeping position detection airbag 1, for example, Figure 8 As shown in the following table.

[0042] The above description is for the case where the bedding is a pillow. When the bedding is a pillow 100, the sleeping posture detection airbag 1, the barometer 4, the controller 3 and the height adjustment mechanism 2 are built into the pillow 100. Compared with the prior art, it does not cause a foreign body sensation to the sleeping user, and can effectively improve the user's sleep quality.

[0043] According to an embodiment of the utility model, the bedding with a sleeping posture detection mechanism also includes a mattress. When the bedding is a mattress, the sleeping posture detection airbag 1, the barometer 4, the controller 3 and the height adjustment mechanism 2 are integrated with the mattress as a part of the mattress. Fig.10 The bedding is a mattress 200, and (a) to (c) show, from top to bottom, a top view of the mattress 200, a side view when the user is lying on his back, and a side view when the user is lying on his side. Fig.10 In the embodiment, except that the bedding is a mattress 200, the other components are substantially the same as the previous case where the bedding is a pillow 100. As the sleeping posture detection airbag 1 and the height adjustment mechanism 2, there is shown Figure 4 The height adjustment mechanism 2 is similar to the structure of the single height adjustment airbag 20 above the sleeping position detection airbag 1, but those skilled in the art can understand that Fig.10 The diagram in the figure is only an example, and you can also use the same method as before, including Figure 3~Figure 9 Any structure similar to the one in the above.

[0044] The above is only used to illustrate the technical solution of the utility model and is not restrictive. Other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the utility model shall be included in the scope of the claims of the utility model as long as they do not deviate from the spirit and gist of the technical solution of the utility model. The effects recorded in this specification are only illustrative and not limited to this, and there may be other effects.
