Description

Technical Field

[0001] The utility model relates to the field of household articles, in particular to a cushion used for reminding people of bad sitting postures. Background Art

[0002] Currently, the design concept of seat cushions on the market is mostly about how to improve the comfort of users. In life, the time spent sitting is usually longer than the time spent standing, and it is unrealistic to maintain the same sitting posture for a long time. Therefore, when maintaining a sitting posture for a long time, it is inevitable that bad sitting postures such as bending over or sitting sideways will occur. If a bad sitting posture is maintained for a long time, it may lead to a variety of health problems, such as cervical spondylosis, lumbar spondylosis, etc. Utility Model Content

[0003] The utility model aims to provide a seat cushion for reminding users of bad sitting postures, and the technical problem to be solved is to remind users in time when they are in bad sitting postures, so as to reduce health problems caused by bad sitting postures.

[0004] The utility model is realized by the following technical solutions:

[0005] A seat cushion for reminding a person of bad sitting posture, comprising a soft cushion and a base, wherein the soft cushion is connected to the base;

[0006] The base comprises a support member and a bottom plate, and the cushion is laid on the upper surface of the support member;

[0007] The upper surface of the support member is provided with a pressure sensor array, and the upper surface of the pressure sensor array contacts the lower surface of the cushion; the pressure sensor array is used to collect the pressure value applied by each point of the cushion to the support member;

[0008] The lower surface of the support member is recessed inward to form a cavity; the upper surface of the bottom plate contacts the lower surface of the support member, and the cavity is blocked by the bottom plate;

[0009] A data processor and an alarm are arranged in the chamber; the data processor is connected to the pressure sensor array and the alarm.

[0010] A pressure sensor array is arranged on the upper surface of the above-mentioned support member instead of a single pressure sensor. This array layout can cover multiple locations of the cushion and realize multi-point monitoring of the user's sitting posture. Compared with single-point monitoring, multi-point monitoring can more comprehensively reflect the pressure distribution of the user's buttocks and legs, thereby improving the comprehensiveness and accuracy of data collection. The pressure sensor array is in direct contact with the lower surface of the cushion, reducing the gap or unevenness that may exist between the pressure sensor and the cushion, ensuring the directness of pressure transmission, thereby improving the accuracy of pressure measurement. The lower surface of the support member is recessed inward to form a chamber, and is sealed by a bottom plate, providing a relatively closed and stable working environment for electronic components such as a data processor, and effectively isolating the interference of the external environment (such as temperature, humidity, vibration, etc.) on the electronic components. The data processor can receive the pressure value from the pressure sensor array in real time, process the pressure value, and determine whether the user is in a bad sitting posture according to the distribution of the pressure value, providing a basis for subsequent alarm reminders. The alarm is connected to the data processor and issues a reminder according to the determination result of the data processor.

[0011] Furthermore, the middle portion of the support member is raised upward, and the raised portion forms a boss;

[0012] The cushion is laid on the convex platform.

[0013] The above-mentioned boss enables the cushion to better fit the natural curves of the buttocks and legs when the user sits down; due to the presence of the boss, the force of the human body weight on the cushion is concentrated in the middle of the cushion, avoiding incorrect sitting posture judgment caused by excessive force on the legs; the boss reduces the possibility of local over-compression of the cushion, which helps the pressure sensor to obtain more accurate pressure distribution data; the wrapping design of the boss and the cushion, on the one hand, reduces the sensor position offset or instability caused by user movement or sitting posture changes, ensuring that the sensor can continuously and accurately collect data during long-term use, and reducing measurement errors caused by external factors; on the other hand, the cushion is in contact with the user, which improves the user's comfortable touch and enhances the overall comfort of the cushion.

[0014] Furthermore, the pressure sensor array includes a first array, and the first array is laid on the top wall of the boss.

[0015] The pressure sensor array may also include a second array and a third array;

[0016] The distance between adjacent pressure sensors in the first array is smaller than the distance between adjacent pressure sensors in the third array; the distance between adjacent pressure sensors in the third array is smaller than the distance between adjacent pressure sensors in the second array;

[0017] The first array is laid on the top wall of the boss;

[0018] The second array is laid on the side wall of the boss;

[0019] The third array is laid on the side of the boss.

[0020] The top wall of the above-mentioned boss is the concentrated force area of ​​the buttocks. The first array with the smallest distance between adjacent pressure sensors is laid on the top wall of the boss, which can capture more subtle pressure changes and improve the accuracy of pressure distribution analysis; although the side of the boss is not the concentrated force area of ​​the buttocks, it is in the concentrated force area of ​​the legs. Therefore, the second array with a smaller distance between adjacent pressure sensors is laid on the side of the boss; during the use of the seat cushion, although the pressure change is not as significant as the top wall, the change in leg position will affect the pressure distribution of the data collected by the third array; the side walls of the boss are mainly subjected to lateral squeezing or bending force from the legs, and the distance between adjacent sensors is increased compared with the first and third arrays, which not only takes cost-effectiveness into consideration, but also ensures sufficient pressure detection coverage and accuracy in the side wall area; the first array, the second array and the third array are layered at different positions of the support, which not only optimizes the layout of the pressure sensors, but also adjusts the density of the sensors according to the needs of different areas, thereby improving the distribution accuracy of pressure detection.

[0021] Furthermore, the cushion also includes a surface cloth;

[0022] The surface cloth is covered on the outside of the cushion and the support, and the edge of the surface cloth extends to the lower surface of the support;

[0023] The edge portion of the face cloth is connected to the supporting member.

[0024] The above-mentioned surface cloth serves as the outer layer of the seat cushion, covering the outside of the soft cushion and the support member, which can reduce direct damage to the soft cushion and the support member by external factors, and help to extend the service life of the seat cushion; considering that the edge of the surface cloth may scratch the user, the edge of the surface cloth is extended to the lower surface of the support member. Since the lower surface of the support member is in contact with the bottom plate, the edge of the surface cloth is avoided from directly contacting the user, solving the problem that the edge of the surface cloth may scratch the user; the edge of the surface cloth is connected to the support member to prevent the surface cloth from falling off due to user activities or external forces during use.

[0025] Furthermore, the lower surface of the cushion is concave inward to form a groove;

[0026] The boss is inserted into the groove.

[0027] Furthermore, the thickness of the cushions on both sides of the boss is greater than the thickness of the cushion directly above the boss.

[0028] The side walls of the above-mentioned bosses are often the side areas where the user's body contacts the seat cushion. These areas may be subjected to greater lateral pressure or twisting force when sitting; increasing the thickness of the side wall cushions can provide better support and cushioning effects, and reduce the user's discomfort caused by long-term sitting or body movement; by adjusting the thickness of the cushions, the pressure of the user's body on the seat cushion is distributed. Although thicker cushions have better comfort, they will increase the pressure area of ​​the pressure sensor, thereby affecting the pressure value collected by the pressure sensor; since the force-bearing area of ​​the buttocks is concentrated on the top wall of the boss, when judging the sitting posture, the pressure value distribution in this area directly affects the judgment result, while the side walls of the boss mainly measure the lateral pressure or twisting force of the legs, which has little effect on the judgment result of the sitting posture; therefore, the thickness of the cushion located on the top wall of the boss is reduced to reduce the degree of pressure dispersion in this area.

[0029] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0030] A pressure sensor array is arranged on the upper surface of the above-mentioned support member instead of a single pressure sensor. This array layout can cover multiple locations of the cushion and realize multi-point monitoring of the user's sitting posture. Compared with single-point monitoring, multi-point monitoring can more comprehensively reflect the pressure distribution of the user's buttocks and legs, thereby improving the comprehensiveness and accuracy of data collection. The pressure sensor array is in direct contact with the lower surface of the cushion, reducing the gap or unevenness that may exist between the pressure sensor and the cushion, ensuring the directness of pressure transmission, thereby improving the accuracy of pressure measurement. The lower surface of the support member is recessed inward to form a chamber, and is sealed by a bottom plate, providing a relatively closed and stable working environment for electronic components such as a data processor, and effectively isolating the interference of the external environment (such as temperature, humidity, vibration, etc.) on the electronic components. The data processor can receive the pressure value from the pressure sensor array in real time, process the pressure value, and determine whether the user is in a bad sitting posture according to the distribution of the pressure value, providing a basis for subsequent alarm reminders. The alarm is connected to the data processor and issues a reminder according to the determination result of the data processor. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0039] In the prior art, when a user sits on a cushion with legs together, the buttocks and legs apply force to the pressure sensor. Since the pressure value collected by the pressure sensor is affected by the force direction, if the force is applied vertically, the pressure value collected by the pressure sensor is the actual applied pressure; if the force is applied obliquely, the pressure value collected by the pressure sensor is less than the actual applied pressure, and the pressure less than the actual applied pressure is included in the sitting posture determination, which is easy to cause the problem of incorrect sitting posture determination. To solve this problem, the following embodiments are provided.

[0040] Example 1

[0041] Combination Figure 1 , this embodiment 1 provides a seat cushion for bad sitting posture reminder, including a soft cushion 1 and a base 5, and the soft cushion 1 is connected to the base 5;

[0042] The base 5 comprises a support member 3 and a bottom plate 4, and the cushion 1 is laid on the upper surface of the support member 3; the base is made of PP polypropylene material;

[0043] The upper surface of the support member 3 is provided with a pressure sensor array 2 (the pressure sensor can be any one or more of a thin film pressure sensor, a weighing sensor and a piezoelectric ceramic sensor, etc.), and the lower surface of the soft pad 1 is provided with a convex point array. The upper surface of the pressure sensor array 2 is in contact with the lower surface of the soft pad 1. The pressure sensor array 2 is used to collect the pressure value applied to the support member 3 by each point of the soft pad 1; each pressure sensor on the pressure sensor array 2 corresponds to each convex point on the convex point array one by one, and the pressure on the soft pad 1 is concentratedly transmitted to the corresponding pressure sensor through the convex point, so that the pressure value collected by the pressure sensor is more accurate;

[0044] The lower surface of the support member 3 is recessed inward to form a chamber 31; the upper surface of the bottom plate 4 is in contact with the lower surface of the support member 3, the bottom plate 4 and the support member 3 are connected by bolts, and the chamber 31 is blocked by the bottom plate 4; in order to prevent the chamber 31 from deforming after sitting for a long time, a plurality of support columns can be arranged in the chamber to enhance the support strength of the support member;

[0045] The chamber 31 is provided with a data processor 6 (which may be a single chip microcomputer, PLC, etc.), an alarm 7 (which may be a loudspeaker) and a power supply module; the data processor 6 is connected to the pressure sensor array 2 and the alarm 7. The power supply module is connected to the pressure sensor array 2, the data processor 6, the alarm 7 and the vibrator, and the power supply module may be any one of a dry cell, a lithium battery, a solid-state battery, and a power adapter. In addition to the loudspeaker, the alarm for reminding the user may also be a vibrator and a wireless communication terminal. The vibrator is nested in the cushion 1, and the vibrator is connected to the data processor 6. The wireless communication terminal is connected to the data processor 6 for communication to realize signal transmission. The wireless communication terminal can both receive alarms and send control instructions.

[0046] The above-mentioned data processor 6 adopts the existing method to realize sitting posture determination, for example: a reference atlas of pressure value distribution in normal sitting posture is entered into the data processor 6, and then the pressure values ​​collected by the pressure sensor are arranged according to the position to obtain a pressure value distribution map, and then the pressure value distribution reference atlas is matched with the pressure value distribution map. If the match is successful, it is a normal sitting posture, otherwise it is an improper sitting posture.

[0047] A pressure sensor array 2 is arranged on the upper surface of the above-mentioned support member 3 instead of a single pressure sensor. This array layout can cover multiple sites of the cushion 1 to achieve multi-point monitoring of the user's sitting posture. Compared with single-point monitoring, multi-point monitoring can more comprehensively reflect the pressure distribution of the user's buttocks and legs, thereby improving the comprehensiveness and accuracy of data collection. The pressure sensor array 2 is in direct contact with the lower surface of the cushion 1, reducing the gap or unevenness that may exist between the pressure sensor and the cushion 1, ensuring the directness of pressure transmission, thereby improving the accuracy of pressure measurement. The lower surface of the support member 3 is recessed inward to form a chamber 31, and is blocked by the bottom plate 4, providing a relatively closed and stable working environment for electronic components such as the data processor 6, and effectively isolating the interference of the external environment (such as temperature, humidity, vibration, etc.) on the electronic components. The data processor 6 can receive the pressure value from the pressure sensor array 2 in real time, process the pressure value, and determine whether the user is in a bad sitting posture according to the distribution of the pressure value, providing a basis for subsequent alarm reminders. The alarm 7 is connected to the data processor 6 and issues a reminder according to the determination result of the data processor 6.

[0048] Example 2

[0049] Based on Example 1, Figure 2 and Figure 3 The middle part of the support member 3 is raised upward, and the raised part forms a boss 32;

[0050] The cushion 1 is placed on the boss 32 .

[0051] The above-mentioned boss 32 enables the cushion 1 to better fit the natural curves of the buttocks and legs when the user sits down; due to the presence of the boss 32, the force of the human body weight on the cushion 1 is concentrated in the middle part of the cushion 1, avoiding the wrong sitting posture judgment caused by excessive force on the legs; the boss 32 reduces the possibility of local over-compression of the cushion 1, which helps the pressure sensor to obtain more accurate pressure distribution data; the covering design of the boss 32 and the cushion 1, on the one hand, reduces the sensor position offset or instability caused by user movement or sitting posture changes, ensuring that the sensor can continuously and accurately collect data during long-term use, and reducing measurement errors caused by external factors; on the other hand, the cushion 1 is in contact with the user, which improves the user's comfortable touch and enhances the overall comfort of the cushion.

[0052] Specific embodiments, combined with Figure 3 The pressure sensor array 2 includes a first array 21 , which is laid on the top wall of the boss 32 .

[0053] The pressure sensor array 2 may further include a second array 22 and a third array 23;

[0054] The distance between adjacent pressure sensors in the first array 21 is smaller than the distance between adjacent pressure sensors in the third array 23; the distance between adjacent pressure sensors in the third array 23 is smaller than the distance between adjacent pressure sensors in the second array 22;

[0055] The first array 21 is laid on the top wall of the boss 32;

[0056] The second array 22 is laid on the side wall of the boss 32;

[0057] The third array 23 is laid beside the boss 32 .

[0058] The boss 32 may be rectangular, arc-shaped, circular, or other special shapes, such as a wave shape.

[0059] When the boss 32 is rectangular, the first array 21 is laid on the top of the boss 32;

[0060] The second array 22 is laid on the side of the boss 32;

[0061] The third array 23 is laid beside the boss 32 .

[0062] When the boss 32 is arc-shaped, the first array 21 is laid on the convex point area of ​​the boss 32 ; the second array 22 is laid on the remaining area of ​​the boss 32 ; and the third array 23 is laid on the side of the boss 32 .

[0063] The top wall of the boss 32 is the concentrated force area of ​​the buttocks. The first array 21 with the smallest distance between adjacent pressure sensors is laid on the top wall of the boss 32, so that the pressure sensor is more sensitive to pressure changes, the sensitivity of data acquisition is improved, and more subtle pressure changes can be captured, thereby improving the accuracy of pressure distribution analysis; although the side of the boss 32 is not the concentrated force area of ​​the buttocks, it is in the concentrated force area of ​​the legs. Therefore, the second array 22 with a smaller distance between adjacent pressure sensors is laid on the side of the boss 32; during the use of the seat cushion, although the pressure change is not as significant as the top wall, the pressure change of the legs is The change in the position of the legs will affect the pressure distribution of the data collected by the third array 23; the side wall of the boss 32 is mainly subjected to lateral squeezing or bending force from the legs, and the spacing between adjacent sensors is increased compared to the first array 21 and the third array 23, which not only takes into account cost-effectiveness, but also ensures sufficient pressure detection coverage and accuracy in the side wall area; the first array 21, the second array 22 and the third array 23 are layered at different positions of the support 3, which not only optimizes the layout of the pressure sensors, but also adjusts the density of the sensors according to the needs of different areas, thereby improving the distribution accuracy of pressure detection.

[0064] Example 3

[0065] Based on Example 2, Figure 4 , the edge of the cushion 1 extends beyond the edge of the support 3.

[0066] The extension of the edge of the soft pad 1 can increase the contact area between the seat cushion and the user's body, thereby providing better stability and support, helping to reduce the tiny movements of the user caused by unstable sitting posture, reducing the interference of these movements on the data collected by the pressure sensor, and thus improving the accuracy of the data; the extension of the edge of the soft pad 1 makes the seat cushion have a certain softness and cushioning at the edge, reducing the chance of direct contact between the user and the hard support part 3, which can not only improve the user's comfort during use, especially when sitting for a long time, but also reduce the pressure and discomfort on the edge of the body; it can also avoid the displacement of the support part 3 caused by direct contact between the user and the support part 3, reducing the impact of the displacement of the support part on the pressure sensor collection.

[0067] In a specific embodiment, the seat cushion further comprises a surface fabric 8; the surface fabric 8 can be made of one or more materials such as triple-proof polyester fabric, genuine leather, PU artificial leather, technological fabric and silicone leather;

[0068] The surface cloth 8 is wrapped around the cushion 1 and the support member 3, and the edge of the surface cloth 8 extends to the lower surface of the support member 3;

[0069] The edge of the surface cloth 8 is connected to the support member 3 by bonding, stapling or other connection methods; a margin is left between the edge side wall of the surface cloth 8 and the support member 3 after connection.

[0070] The above-mentioned surface cloth 8 serves as the outer layer of the seat cushion, covering the outside of the soft cushion 1 and the support member 3, which can reduce the direct damage of external factors to the soft cushion 1 and the support member 3, and help to extend the service life of the seat cushion; considering that the edge of the surface cloth 8 may scratch the user, the edge of the surface cloth 8 is extended to the lower surface of the support member 3. Since the lower surface of the support member 3 is in contact with the bottom plate 4, the edge of the surface cloth 8 is avoided from directly contacting the user, solving the problem that the edge of the surface cloth 8 may scratch the user; the edge of the surface cloth 8 is connected to the support member 3 to prevent the surface cloth 8 from falling off due to user activities or external forces during use.

[0071] In a specific embodiment, the middle portion of the surface cloth 8 is connected to the cushion 1 by bonding, sewing or other connection methods.

[0072] Taking into account that the user moves during the use of the seat cushion and thus causes the surface cloth 8 to shift, the pulling force on the cushion 1 changes after the surface cloth 8 shifts, affecting the pressure value collected by the pressure sensor; connecting the middle part of the surface cloth 8 to the cushion 1 makes the overall structure of the seat cushion more stable, reduces the movement or deformation of the surface cloth 8 during use, ensures that the surface cloth 8 can maintain the stability of shape and position when subjected to external force, and reduces the impact of the displacement of the surface cloth on the pressure sensor collection.

[0073] Example 4

[0074] On the basis of Example 3, since the soft cushion in the prior art usually uses thicker or harder latex or high-density sponge, when the thicker or harder latex or high-density sponge contacts the pressure sensor, the force application area of ​​the latex or high-density sponge is too large, and the pressure is dispersed before being transmitted to the pressure sensor, resulting in a decrease in the acquisition accuracy of each point of the pressure sensor;

[0075] In order to solve the above problem, the thickness of the cushions on both sides of the boss 32 is greater than the thickness of the cushion directly above the boss 32 .

[0076] The side walls of the above-mentioned boss 32 are often the side areas where the user's body contacts the seat cushion. These areas may be subjected to greater lateral pressure or twisting force when sitting; increasing the thickness of the side wall cushion 1 can provide better support and cushioning effects, and reduce the user's discomfort caused by long-term sitting or body movement; by adjusting the thickness of the cushion 1, the pressure of the user's body on the seat cushion is distributed. Although the thicker cushion 1 has better comfort, it will increase the pressure area of ​​the pressure sensor, thereby affecting the pressure value collected by the pressure sensor; since the force-bearing area of ​​the buttocks is concentrated on the top wall of the boss 32, when determining the sitting posture, the pressure value distribution in this area directly affects the determination result, while the side wall of the boss 32 mainly measures the lateral pressure or twisting force of the legs, which has little effect on the determination result of the sitting posture; therefore, the thickness of the cushion 1 located on the top wall of the boss 32 is reduced to reduce the degree of pressure dispersion in this area.

[0077] For example, the cushion thickness of the top wall of the boss 32 may be 18 to 22 mm. Compared with the cushion thickness of 40 mm in the prior art, the present invention reduces the pressure dispersion in this area.

[0078] The use of the cushion: the backrest component can be connected to the bottom plate to form a legless chair; armrests are arranged on both sides of the bottom plate to form a legless chair with armrests; and a seat frame can also be installed under the bottom plate to serve as a seat for other styles of chairs.

[0079] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
