Description

Technical Field

[0001] The present invention belongs to the technical field of health monitoring, and particularly relates to a head intelligent guiding device, method and system. Background Art

[0002] During sleep, the head posture of the user will constantly change, including various postures such as supine, side-lying, prone, etc. These posture changes have a profound impact on the natural curves of the neck and spine. Appropriate support is crucial for maintaining the health of the cervical vertebrae. However, when the head deviates from the original support height, it may cause excessive pressure on the neck and shoulders, thus affecting sleep quality and overall health. Especially at night, many people habitually turn over or change postures. This dynamic behavior may increase the distance between the head and the support, thereby causing the spine to be in an unnatural state.

[0003] In current technical designs, most products are still static and cannot effectively adapt to the frequently changing head postures of users during sleep. This static design means that when the user's head moves out of the original support range, the product cannot adjust in real time to provide the necessary support. This not only increases the discomfort of the user during sleep but also may lead to a series of health problems, such as stiff neck, cervical pain, shoulder tension and other related discomfort symptoms. Moreover, although many existing products have improved in terms of materials and comfort, they are relatively lagging in intelligent and multifunctional designs, making it difficult for users to obtain timely and effective support when turning over and changing postures.

[0004] In summary, how to provide a head intelligent guiding device is a technical problem that urgently needs to be solved at present. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a head intelligent guiding device, method and system, which can form a ramp with a height difference by adjusting the structure when sensing that the user's head touches the extension area, and guide the user's head to move along the slope direction.

[0006] The present invention provides a head intelligent guiding device, including a device body and a control center. At least one side of the left or right side of the device body is connected with an extension area; a pressure sensor array is arranged on the extension area to sense whether the head touches the extension area; An adjustment structure for adjusting the position of the user's head is arranged on the extension area. The adjustment structure at least includes, a bottom airbag, and a soft layer with a load-bearing surface is arranged on the bottom airbag. By inflating and deflating the bottom airbag, the height of the soft layer relative to the device body is adjusted; A guiding structure is provided between the soft layer and the bottom airbag. A slope with a height difference is formed on the soft layer through the guiding structure to guide the user's head to move along the slope direction.

[0007] Furthermore, an isolation layer is provided between the guiding structure and the bottom airbag.

[0008] Furthermore, the guiding structure includes an upper airbag array composed of several upper airbags. The upper airbag array is selectively communicated with the bottom airbag, or the upper airbag array is arranged on the isolation layer.

[0009] Furthermore, the upper airbag includes a single upper airbag, or includes several mutually superimposed upper sub-airbags, and the upper sub-airbags are selectively communicated with each other.

[0010] Furthermore, the guiding structure includes a flip plate, and the flip plate is rotatably connected to the isolation layer through a hinge connecting member; A locking member is provided on the hinge connecting member to limit the flip plate.

[0011] Alternatively, the guiding structure includes a telescopic structure, and the telescopic structure includes several mutually nested telescopic blocks; and / or the telescopic structure includes a spring assembly.

[0012] Furthermore, the device body is a pillow.

[0013] The present invention provides a guiding method realized by a head intelligent guiding device as described in any one of the above, including the following steps: S1 Determine whether the user's head touches the extended area; S2 When the user's head touches the extended area, collect the position information of the user's head on the extended area; S3 Adjust the height of the soft layer to be flush with the upper surface of the device body through the bottom airbag; Based on the position information of the head on the extended area, trigger at least the guiding structure at this position correspondingly to change the surface shape of the soft layer, so that a slope with a height difference is formed on the surface of the soft layer, and the slope inclines towards the direction of the device body, thereby guiding the user's head to move along the slope direction.

[0014] Furthermore, S1 includes at least one of the following: Compare the number of pressure sensors that detect pressure data with a preset number threshold. If it is greater than the preset number threshold, it is determined that the user's head touches the extended area; Compare the duration of each pressure data with a preset duration threshold. If it is greater than the preset time threshold, it is determined that the user's head touches the extended area; Compare each pressure data with a preset pressure threshold. If it is greater than the preset pressure threshold, it is determined that the user's head touches the extended area; Collect image data of the extended area through an external device, extract part contour information from the image data, compare and match the extracted part contour with the standard contours of each part of the preset user to obtain the part with the highest similarity.

[0015] Further, after the user's head moves along the slope direction in S3, it also includes detecting whether the user's head still touches the extended area. If so, collect the position of the user's head on the extended area again and correspondingly trigger the guiding structure at this position, and repeat the above steps until the user's head does not touch the extended area.

[0016] The present invention provides a system adopting the guiding method described in any one of the above. The system includes, The detection module is configured to detect whether the user's head touches the extended area; The position acquisition module is configured to collect the position of the user's head on the extended area when the user's head touches the extended area; The triggering module is configured to correspondingly trigger the guiding structure at this position based on the position of the head on the extended area to change the surface shape of the soft layer, so that a slope with a height difference is formed on the surface of the soft layer, and the slope inclines towards the direction of the device body, thereby guiding the user's head to move along the slope direction.

[0017] Due to the adoption of the above technical solutions, compared with the prior art, for example, the present invention has the following advantages and positive effects: The contact situation of the user's head on the extended area is sensed in real time through the pressure sensor array, and it is quickly and accurately determined whether at least part of the user's head has left the device body. When the user's head touches the extended area, the guiding structure is triggered to form a slope with a height difference on the soft layer, guiding the user's head to move along the slope direction, so that the user's head can return to the device, effectively solving the problem that the user's head leaves during the turning process, enhancing the functionality and adaptability of the device, ensuring the user's sleep quality, and avoiding a series of physiological health problems such as stiff neck and cervical pain caused by improper head position.

[0018] The overall structure of this device is simple, easy to use, and easy to maintain. The sleeping posture adjustment method based on the device provides a convenient and effective unique way to make the user's head return to the supported state, and has good market application prospects and user acceptance.

[0027] Techniques, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0028] The present invention provides a head intelligent guiding device 100, such as Figure 2 As shown, it includes a device body 200 and a control center (not shown in the figure).

[0029] Particularly, at least one side of the device body 200 is connected to the expansion area 300 , and at least one side of the left side or the right side of the device body 200 is connected to the expansion area 300 .

[0030] The expansion area 300 is provided with a pressure sensor array (not shown in the figure) for sensing whether the head contacts the expansion area 300 .

[0031] The pressure sensor array includes a plurality of pressure sensors evenly or unevenly distributed on the extension area 300. These pressure sensors may be piezoelectric sensors, strain gauges or other types of pressure sensors, which can accurately sense changes in pressure applied to their surfaces.

[0032] When the user's head contacts the expansion area 300, the sensor detects the pressure exerted by the head. Each sensor converts the measured pressure value into an electrical signal and processes it through the control center.

[0033] The expansion area 300 is provided with an adjustment structure for adjusting the position of the user's head, and the adjustment structure at least includes: The bottom airbag 310, the lower surface of the bottom airbag 310 can directly contact the loading surface, or optionally, a support layer is arranged under the bottom airbag 310, directly contacting the loading surface, playing an overall supporting role similar to a base.

[0034] The bottom layer airbag 310 may be a single large airbag, or may include a plurality of bottom layer sub-airbags.

[0035] The bottom airbag 310 can be automatically inflated and deflated, and has a built-in micro air pump, which can automatically adjust the air pressure of the bottom airbag 310 according to the command of the control center. The airbags included in the present invention all adopt a similar configuration and have the function of automatic inflation and deflation.

[0036] A soft layer 330 having a load-bearing surface is disposed on the bottom airbag 310 . When the user's head contacts the expansion area 300 , the user's head is supported by the soft layer 330 .

[0037] Since the bottom airbag 310 is provided below the soft layer 330, when the bottom airbag 310 inflates and expands and deflates and contracts, the height of the soft layer 330 will also change accordingly, thereby realizing the height adjustment of the soft layer 330 relative to the device body 200.

[0038] A guiding structure 400 for guiding the user's head to move in the direction of the device body 200 is provided between the soft layer 330 and the bottom airbag 310.

[0039] The guiding structure 400 can be directly provided on the bottom airbag 310, reducing the complexity of the overall structure and facilitating manufacturing and assembly. Or, considering the soft characteristics of the bottom airbag 310, further, the bottom airbag 310 is connected through an isolation layer 320 with higher hardness. The isolation layer 320 can assist in bearing the weight of the user's head, dispersing the pressure exerted by the user's head on the overall adjustment structure, and providing additional stable supporting force.

[0040] In addition, the isolation layer 320 with higher hardness can absorb and reduce the noise and vibration transmission during the inflation and deflation of the airbag to a certain extent, providing a quieter and more comfortable use environment, which is particularly important during sleep.

[0041] The isolation layer 320 with higher density usually performs better in terms of durability and elasticity, can withstand long-term use without being easily deformed or damaged, thereby extending the service life of the entire device.

[0042] The guiding structure 400 includes an upper airbag 411 array 410 composed of a plurality of upper airbags 411. In the case where the isolation layer 320 is not provided, the upper airbag 411 array 410 is selectively communicated with the bottom airbag 310.

[0043] Specifically, a gate is provided at the connection between the upper airbag 411 array 410 and the bottom airbag 310. When the gate is opened, gas can flow between the upper airbag 411 array 410 and the bottom airbag 310. If you want to control the gas flow direction, you can choose one-way gates such as spherical one-way valves, diaphragm one-way valves, and gravity one-way valves, so that the gas can only flow from the bottom airbag 310 to the upper airbag 411 array 410.

[0044] In another implementation, as Figure 3 shown, the upper airbag 411 array 410 is provided on the isolation layer 320. In this way, the upper airbag 411 array 410 has a separate inflation and deflation device, which is independent of the inflation and deflation mechanism of the bottom airbag 310 and does not affect each other.

[0045] The upper airbag 411 includes a single upper airbag 411, or is a composite tower structure including a number of stacked upper sub-airbags (not shown in the figure), and the upper sub-airbags are selectively interconnected with each other.

[0046] By selectively connecting or isolating each upper sub-airbag, the control center can flexibly adjust the gas flow and pressure as needed. For example, some airbags can be inflated while others remain empty, thereby achieving different buoyancy or support effects.

[0047] The airbags can protect each other to a certain extent, reduce the impact of the external environment on the airbags, thereby improving the gas sealing performance and reducing the risk of air leakage. And if a certain airbag fails, other airbags can still provide support and functions, thus ensuring the safety and stability of the overall structure.

[0048] In another embodiment, as Figure 5 shown, the guiding structure 400 includes a flip plate 430, and the flip plate 430 is hingedly connected to the isolation layer 320.

[0049] The hinge connection of the flip plate 430 serves as the rotation center, allowing the flip plate 430 to rotate around its axis at this point. As the flip plate 430 rotates, the angle between the flip plate 430 and the isolation layer 320 changes, and the flip plate 430 and the isolation layer 320 together form slopes with different gradients. The angle between the flip plate 430 and the isolation layer 320 determines the gradient size.

[0050] A locking member is provided on the hinge connecting member 431 to limit the flip plate 430. After the flip plate 430 is flipped to a certain position, the angle between the flip plate 430 and the isolation layer 320 is fixed by the locking member. In this way, when the user's head contacts the flip plate 430, the flip plate 430 will not shift due to pressure and can support the user's head.

[0051] By way of example and not limitation, the locking member can be a mechanical locking member. For example, a gear structure is provided at the hinge connection of the flip plate 430 and the isolation layer 320. This structure includes a gear and a corresponding rack. When the flip plate 430 rotates, the gear meshes with the rack, and when the flip plate 430 rotates to a predetermined angle, the meshing of the gear and the rack forms a lock.

[0052] A spring locking member can also be selected. For example, when the flip plate 430 rotates to a predetermined angle, the spring is compressed and releases a locking hook, and the hook catches into the notch on the flip plate 430, thereby locking the flip plate 430.

[0053] In addition, an electromagnetic locking member can also be selected. An electromagnet is installed at the connection between the flip plate 430 and the isolation layer 320. When the flip plate is flipped to the desired angle, the electromagnet is automatically activated and adsorbs and fixes the flip plate 430.

[0054] In another embodiment, as Figure 4 shown, the guiding structure 400 includes a telescopic structure 420, and the telescopic structure 420 includes a plurality of telescopic blocks 421 nested with each other; and / or, the telescopic structure 420 includes a spring assembly. The driving assembly is used to drive the telescopic structure 420 to automatically expand and contract.

[0055] The different overall lengths of the telescopic structures 420 after expansion and contraction result in a height difference between the telescopic structures 420. The height difference appears as a slope on the soft layer 330, and the different height differences determine the size of the slope.

[0056] In summary, the guiding structure 400 can apply an upward pressure to the soft layer 330, causing a change in the shape of the load-bearing surface of the soft layer 330 and forming a slope with a height difference on the soft layer 330. When the user's head is on the slope, under the action of gravity, it tends to move along the slope direction to the side with a lower height, thereby completing the adjustment of the head position.

[0057] The above-mentioned device body is a pillow.

[0058] The present invention provides a guiding method implemented by the head intelligent guiding device 100 as described in any one of the above, as Figure 1 shown, including the following steps: S1 Detect whether the user's head touches the extension area 300.

[0059] In specific implementation, there can be the following two processing methods. First, as long as any one of the pressure sensors in the pressure sensor array detects a pressure value, it is determined that the user's head touches the extension area 300.

[0060] Or, by comparing the preset pressure threshold, the effective pressure data is screened as the basis for determination. When any one of the pressure sensors in the pressure sensor array detects pressure data greater than the preset threshold, it is determined that the user's head touches the extension area 300.

[0061] Furthermore, when the user turns over, it may not be the head that touches the extension area 300, but the hand or the arm area touches the extension area 300. The following methods can be used to distinguish and identify different contact situations: First, add a threshold for the number of activated pressure sensors to the determination criterion.

[0062] For example, if the number of detected pressure sensors exceeds a preset threshold, it can be inferred that it is a head contact; otherwise, it may be a hand or arm contact.

[0063] And / or, analyze by duration; for example, head contact usually lasts for a longer time, while hand or arm contact may be brief. The rapid response ability of the sensor can also be utilized to detect the instantaneousness of pressure changes. If the pressure changes rapidly within a short period of time, it may be that the arm or hand re - contacts; if the pressure changes slowly and steadily, it is more likely to be a head contact.

[0064] And / or, set different pressure thresholds for different contact parts, namely the head, hand, and arm. For example, the head may exert a greater pressure, while the pressure exerted by the arm or hand may be smaller.

[0065] And / or, through contour detection, analyze the image or pressure sensor data to identify the edges and shapes of parts of the contact expansion area 300, compare the obtained part contours with the preset standard contours of the user's head, hand, and arm respectively, obtain the most similar matching result, and determine whether the part is the head, hand, or arm based on the matching result. Contour detection can be achieved using existing algorithm steps and will not be elaborated in detail here.

[0066] Calculate the areas of different contours, which can further determine the contact part. For example, the head usually occupies a larger contact area, while the contact area of the hand or arm is smaller.

[0067] It is also possible to combine external devices including cameras, mobile phones, tablets, and smartwatches for image acquisition to assist in the judgment.

[0068] When S2 detects that the user's head contacts the expansion area 300, collect the position information of the user's head on the expansion area 300.

[0069] The collection method is for example only and not limited. It can be carried out in the following ways: Because the pressure sensor array on the expansion area 300, including several pressure sensors distributed within the range of the expansion area 300, can be distributed in a grid form or other reasonable layouts, the position of each pressure sensor on the expansion area 300 is relatively fixed.

[0070] Taking the grid form as an example, within the expansion area 300, the pressure sensors are evenly distributed in a grid form. The grid consists of rows and columns, and the spacing between sensors can be adjusted according to design requirements, such as the spacing between each sensor being 1 cm, etc. The grid layout can ensure uniform coverage of the entire expansion area 300, effectively detect different positions of the head within the expansion area 300, and provide more accurate pressure distribution information.

[0071] Other layout methods can also choose non-uniform layout. According to the user's usage habits or the expected distribution of the head position, for example, more sensors can be placed in the area where the user's head may come into contact more frequently (such as the central area), and fewer sensors can be placed in the area near the edge. This layout can make more efficient use of sensor resources, reduce the number of unnecessary sensors, and maintain high sensitivity and accuracy at the same time.

[0072] Select an origin within the expansion area 300. The origin can be set at a corner or the center position of the expansion area 300. Each pressure sensor corresponds to a unique coordinate, (X1, Y1) (X2, Y2)......(Xn, Yn).

[0073] Obtain the coordinates of the pressure sensors that detect the pressure data, and calculate the position information of the user's head through these coordinates.

[0074] The position information of the user's head includes the head center position, the head contact area, the pressure distribution characteristics, the dynamic changes, and the head posture information.

[0075] Calculate the coordinates corresponding to the sensor with the maximum pressure by the weighted average method to obtain the center coordinates (xhead, yhead) of the head. The center coordinates usually correspond to the area where the head is in the closest contact with the expansion area 300.

[0076] Based on the number and distribution positions of the sensors that detect the pressure, the shape characteristics of the area where the head contacts the expansion area 300 and the size of the contact area can be reflected.

[0077] Based on the pressure distribution characteristics detected between the pressure sensors, such as the maximum pressure value, the minimum pressure value, and the differences in the pressure values detected by each pressure sensor, the tilt direction and angle of the head can be inferred. For example, if the pressure on one side is significantly greater than that on the other side, the tilt direction of the head can be judged.

[0078] S3 adjusts the height of the soft layer 330 to be flush with the upper surface of the device body 200 through the bottom airbag 310.

[0079] As Figure 3 shown, in the default state, the bottom airbag 310 is in an uninflated state, and the soft layer 330 located at the top layer of the adjustment structure is lower than the upper surface height of the device body 200.

[0080] S3 triggers at least the guiding structure 400 at that position corresponding to the position information of the head on the expansion area 300 to change the surface shape of the soft layer 330.

[0081] Taking the upper airbag 411 array 410 as an example, each upper airbag 411 in the array is numbered according to its position, such as the upper airbag 411 in the X-th row and Y-th column.

[0082] In this embodiment, the expansion area 300 is arranged on the right side of the device body 200; the upper airbag 411 at the uppermost left corner point of the expansion area 300 is used as the first row and the first column in the array.

[0083] Suppose the user's head touches the upper airbag in the first row and the second column (airbag A), the upper airbag in the first row and the third column (airbag B), the upper airbag in the second row and the second column (airbag C), and the upper airbag in the second row and the third column (airbag D).

[0084] Since the expansion area 300 is arranged on the right side of the device body 200, in order to make the user's head move from the expansion area 300 to the device body 200, a slope inclined from right to left should be set. This means that the height of the airbag closer to the device body 200 should be lower, while the height of the airbag closer to the right side of the expansion area 300 should be higher.

[0085] Airbags A and C are closer to the device body 200 than airbags B and D. Therefore, when setting the height, the height of airbags A and C after inflation should not be higher than the height of airbags B and D after inflation.

[0086] The relative height between airbags B and D can be the same height or different heights, as long as it is within the range higher than the height of airbags A and C after inflation.

[0087] Similarly, the same applies to airbags A and C.

[0088] For example, it can be set in the following way: Airbag D: The highest (for example, set to a height of 4) to form the starting point of the slope.

[0089] Airbag B: Higher (for example, set to a height of 3). Slightly lower than airbag D.

[0090] Airbag C: Lower (for example, set to a height of 2). The height should be lower than airbag B to maintain the inclination of the slope.

[0091] Airbag A: The lowest (for example, set to a height of 1) to form a smooth transition to the device body 200.

[0092] Through this setting, a slope inclined from right to left is formed on the soft layer 330, and the user's head will be guided by gravity and the slope, which helps to move to the left and finally slide into the area of the device body 200.

[0093] For the case where the expansion area 300 is on the left side of the device body 200, it is completely opposite to the case where the expansion area 300 is on the right side of the device body 200. That is, in order to move the user's head from the expansion area 300 to the device body 200 located on the right side of the expansion area 300, a slope inclined from left to right should be set.

[0094] In order to move the user's head from the expansion area 300 to the device body 200, a slope inclined from left to right should be set. This means that the height of the airbag closer to the device body 200 should be lower, while the height of the airbag closer to the left side of the expansion area 300 should be higher.

[0095] Taking the upper airbag 411 at the uppermost left corner point of the expansion area 300 as the first row and first column in the array, assuming the array has a total of three rows and four columns.

[0096] The user's head touches airbag E (the first row and third column), airbag F (the first row and fourth column), airbag G (the second row and third column), and airbag H (the second row and fourth column).

[0097] For example, it can be set in the following way: Airbag E: The highest (for example, set to a height of 4). It should be set as the highest among these airbags to form the starting point of the slope.

[0098] Airbag F: The same height as airbag E, set to a height of 4.

[0099] Airbag G: The height is lower than airbags E and F (for example, set to a height of 2) to maintain the slope.

[0100] Airbag H: The same height as airbag G.

[0101] Through this setting, the height of the airbags gradually decreases from left to right, forming a slope inclined from left to right, guiding the user's head to transition from the expansion area 300 to the device body 200 located on the right side of the expansion area 300.

[0102] As Figure 4 shown, the implementation of the spring (not shown in the figure) and the telescopic structure 420 is similar to referring to the array 410 of the upper airbag 411.

[0103] The implementation process of the flip plate 430 can be carried out in the following way: For example, several flip plates 430 are provided below the soft layer 330, located in the upper left area, lower left area, central area, upper right area, and lower right area of the expansion area 300 respectively.

[0104] When the user's head touches the central area of the extension area 300, then when the extension area 300 is on the right side of the device body 200, the flip plate 430 in the central area is triggered to rotate along the hinge connection, causing the flip plate 430 to tilt up, lower on the left and higher on the right, thereby forming a slope inclined to the left on the surface of the soft layer 330, as Figure 5 shown.

[0105] If the extension area 300 is on the left side of the device body 200, then the flipping direction of the flip plate 430 is opposite to the above, higher on the left and lower on the right, facilitating the movement of the user's head towards the extended body on the right side.

[0106] Through any one of the guiding structures 400 described above, a slope with a height difference is formed on the surface of the soft layer 330, and this slope is inclined towards the device body 200, thereby guiding the user's head to move along the slope direction.

[0107] S3 further includes, after the user's head moves along the slope direction, detecting whether the user's head still touches the extension area 300.
