[0002] Correct sitting posture can keep the spine in its natural physiological curvature, evenly distribute the pressure between vertebrae, and is conducive to the normal growth and development of the spine. If the sitting posture is bad, such as long-term hunching or sitting sideways, the spine will be forced into an abnormal bending state, which will cause uneven force on the vertebrae. Over time, it may cause problems such as scoliosis and hunchback, which not only affect the appearance of the body, but also limit the development of the thorax, and further affect the cardiopulmonary function. Cervical spine: When children maintain a correct sitting posture and the head, neck and spine are in a straight line, the pressure on the cervical spine is within the normal range, which is conducive to the healthy development of the cervical spine.

[0003] Nowadays, children's sitting posture correction chairs can be used to help children develop correct sitting postures, protect spinal health, and prevent myopia and other problems.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0035] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0037] The present invention provides Figure 1 , Figure 2 and Figure 3 As shown, a new type of sitting posture correction chair is used to help users develop a correct sitting posture, especially children. Protect the user's spinal health and prevent myopia and other problems; the main structure of the present invention includes: a seat body 1, a backrest airbag assembly 2 and an air pump device 3. The seat body 1 is provided with a seat back 11 and a seat cushion 12, wherein the seat back 11 and the seat cushion 12 are used to support the user's back and buttocks respectively; the backrest airbag assembly 2 includes a plurality of backrest telescopic parts 21, and the plurality of backrest telescopic parts 21 are arranged along the longitudinal direction of the seat back 11. The backrest telescopic parts 21 are provided with backrest airbags 22, and the backrest telescopic parts 21 are used to telescopically adjust the backrest airbags 22, and adjust the forward extension length of the backrest airbags 22, and the backrest airbags 22 are used to support the user's back. According to the telescopic amount of the plurality of backrest telescopic parts 21, the support surfaces of the plurality of backrest airbags 22 can form a curved support arc, and the support arc is used to match the back support of the current user in the standard sitting posture.

[0038] In addition, the backrest airbag 22 is provided with an air pressure sensor 221, which is used to detect the air pressure value of the backrest airbag 22. Among them, the seat back 11 is provided with a height measuring device 4, which is used to measure the height of the left and right shoulders of the user and the height difference between the left and right shoulders. Further, the air pump device 3 is connected to the backrest airbag 22 pipeline, and the air pump device 3 is used to adjust the air pressure of the backrest airbag 22;

[0039] It is understandable that when the user leans against the backrest airbag 22, the internal air pressure of the backrest airbag 22 increases under the pressure of the user's back. Therefore, the pressure value read by the air pressure sensor 221 can be used to obtain the degree of compression of the backrest airbag 22. Combining the pressure values ​​of multiple air pressure sensors 221, the host can determine whether the user's back is leaning against the arranged backrest airbags 22 in a standard posture.

[0040] The air pressure inside the backrest airbag 22 needs to be adjusted before use. The air pressure inside several backrest airbags 22 is adjusted to a preset standard value so that when the user sits on the seat body 1, the air pressure sensor 221 can read the accurate pressure change. Therefore, it is necessary to connect an air pump device 3 to each backrest airbag 22.

[0041] It should be noted that today's children's sitting posture correction chairs usually need to be specially customized according to the patient's height or age, so that the seat back 11 or cushion 12 of the children's sitting posture correction chair can adapt to the child's height. Then the children's sitting posture correction chair can normally correct the child's sitting posture. However, with the increase of age, the height and weight of children also increase rapidly, and the height of the child's cervical spine, thoracic spine, lumbar spine and sacral spine corresponding to the table and chair backrest will change. Then it will cause the customized sitting posture correction chair purchased early to be prematurely incompatible with the child's height and weight. Moreover, this kind of sitting posture correction chair that needs to be specially customized for children's height is relatively expensive and is not suitable for mass production and promotion.

[0042] This solution can adjust the backrest telescopic member 21 on the seat back 11 according to the user's shoulder height, so that the support of the seat back 11 can be adjusted to a standard support arc, so that the sitting posture correction chair can be adapted to users of different heights, and the sitting posture correction effect is more accurate. Then, the air pressure sensor 221 of the backrest airbag 22 is used to detect whether the user's sitting posture is standard. In addition, this solution can also measure the height difference between the left and right shoulders of the user through the height measurement device 4 to evaluate the user's scoliosis.

[0043] When using the posture correction chair of this solution, it is necessary to first guide the user to sit on the seat body 1 according to the standard sitting posture, and first measure the height of the left and right shoulders of the user through the height measuring device 4. Among them, the length of the user's spine and the position of the user's cervical spine, thoracic spine, lumbar spine and sacral spine can be calculated through the distance between the measuring end of the height measuring device 4 and the support part of the seat cushion 12 when the user is in a sitting posture. Then, through the height of the user's shoulders. Finally, adjust the expansion and contraction amount of several backrest telescopic parts 21 so that the support surfaces of several backrest airbags 22 form a curved support arc, and match the back support of the current user in the standard sitting posture through the support arc. Therefore, the posture correction chair of this solution can be adapted to users of different heights, and the posture correction effect is more accurate.

[0044] Further, such as Figure 2 , Figure 4 and Figure 6As shown, the height measuring device 4 includes: at least two rockers 41 and at least two angle sensors 42. The rocker 41 is provided with a connecting end 411 and abutting end 412. The two rockers 41 are movably connected to the upper end of the seat back 11 through the two abutting ends 412 respectively. The abutting ends 412 are used to abut on the user's shoulders. The two angle sensors 42 are used to measure the angles between the two rockers 41 and the seat back 11 respectively.

[0045] In this embodiment, the user's shoulder height is measured by the rocker 41. It is understandable that after the user sits on the seat body 1 in a standard sitting posture, the rocker 41 may sag under the action of external force or gravity, and the abutting end 412 of the rocker 41 will abut against the user's shoulder. Since the shape and length of the rocker 41 are constant. Therefore, the angle sensor 42 can measure the angle between the connecting end 411 of the rocker 41 and the seat back 11, and the host can calculate the user's shoulder height through the angle between the connecting end 411 and the seat back 11.

[0046] Further, such as Figure 2 , Figure 4 As shown, the axis of the movable axis of the rocker 41 is horizontally arranged, so the abutting end 412 of the rocker 41 can move around the axis of the movable axis of the rocker 41. The rocker 41 is an arc-shaped rod, and the arc-shaped rod extends in the direction of a parabola. The inner arc portion of the arc-shaped rod can avoid obstacles, such as the user's hair. Therefore, the curved rocker 41 can make the abutting end 412 have a larger range of movement, and can avoid affecting the range of movement of the user's head.

[0047] Further, such as Figure 2 , Figure 4 and Figure 6 As shown, a buffer 413 is provided at one end of the rocker 41 away from the seat back 11, and the buffer 413 is used to abut against the user's shoulder. The abutting end 412 abuts against the user's shoulder through the buffer 413. The contact area between the abutting end 412 of the rocker 41 and the user's shoulder is made larger to avoid the abutting end 412 causing an indentation on the user's shoulder. It is understandable that in order to avoid the rocker 41 causing a burden during the long-term contact between the rocker 41 and the user's shoulder, the rocker 41 needs to be made of a lower quality material. In some embodiments, the rocker 41 is a carbon fiber rod.

[0048] Further, such as Figure 2 , Figure 4 and Figure 6As shown, the height measuring device 4 also includes a telescopic component 43, and the telescopic component 43 is used to adjust the distance between the two abutting ends 412 on the two rocking arms 41. It is understandable that the shoulder width and shoulder inclination of different users may be different. Therefore, it is also necessary to adjust the distance between the two abutting ends 412 on the two rocking arms 41 accordingly to adapt to the user's shoulders. Therefore, in this embodiment, the distance between the two abutting ends 412 on the two rocking arms 41 is adjusted by the telescopic component 43. Among them, in the process of adjusting the distance between the two abutting ends 412 on the two rocking arms 41. The two abutting ends 412 need to move the same stroke in opposite directions. In this way, the two abutting ends 412 are always symmetrical.

[0049] Further, such as Figure 6 As shown, a counterweight block 414 is disposed on the connecting end 411, and the counterweight block 414 and the abutting end 412 are disposed relative to each other with the connecting end 411 as the axis, and the counterweight block 414 is used to offset the weight of the rocker 41. It can be understood that the counterweight block 414 can offset a portion of the mass of the rocker 41, thereby reducing the burden on the user's shoulders caused by the abutting end 412 of the rocker 41.

[0050] Further, such as Figure 4 and Figure 5 As shown, the backrest airbag 22 includes a left airbag 222 and a right airbag 223, which are independently arranged, and an air pressure sensor 221 is arranged in each of the left airbag 222 and the right airbag 223. In this embodiment, a plurality of left airbags 222 are arranged longitudinally along the left side of the seat back 11, and a plurality of right airbags 223 are arranged longitudinally along the right side of the seat back 11. The airbag arrays on the left and right sides (the left airbag 222 array and the right airbag 223 array) respectively detect the left and right side pressures applied by the user's back, and can further detect whether the user's back is offset.

[0051] Further, such as Figure 3 , Figure 4 and Figure 5 As shown, the backrest telescopic member 21 is a telescopic airbag, which is used to telescopically adjust the backrest airbag 22. It can be understood that the telescopic airbag has a buffering effect and can effectively improve the comfort of the sitting posture correction chair.

[0052] Further, such as Figure 3 and Figure 4As shown, the seat cushion 12 is provided with a seat cushion 12 airbag assembly, which includes a left seat cushion airbag 51 and a right seat cushion airbag 52, which are respectively provided on the left and right surfaces of the seat cushion 12. It can be understood that the left seat cushion airbag 51 and the right seat cushion airbag 52 are used to detect the pressure exerted by the left thigh and the right thigh of the user, respectively, and can further detect whether the user is sitting on the chair in a normal sitting posture, so as to avoid the user from sitting in an unhealthy posture such as crossing his legs.

[0053] In some embodiments, the posture correction chair can also be equipped with a device with a reminder function such as a speaker to remind the user whether the current sitting posture is standard. In addition, the seat body 1 can also be provided with functional parts such as a display screen. Improve the functionality of the posture correction chair. In some embodiments, the seat back 11 and the seat cushion 12 are also covered with a seat cover to cover the backrest airbag 22 and the seat cushion 12 airbag. Make the outer surface of the seat body 1 smooth and beautiful.

[0054] A second aspect of the present application provides a sitting posture correction method based on the novel sitting posture correction chair as described above, the sitting posture correction method comprising the following steps:

[0055] Step 1: Instruct the user to sit on the chair body 1 according to the standard sitting posture, and place the abutting ends 412 of the two rockers 41 against the user's shoulders;

[0056] It is understandable that after the user sits on the chair body 1 according to the standard sitting posture, the rocker 41 may sag under the action of external force or gravity, and the abutting end 412 of the rocker 41 may abut against the user's shoulder.

[0057] Step 2: two angle sensors 42 are used to collect two sets of angle data between the two rockers 41 and the seat back 11, and based on the relationship parameter between the angle of the rocker 41 and the user's shoulder height, the user's shoulder height data is calculated through the two sets of angle data;

[0058] It is understandable that, since the shape and length of the rocker 41 are constant, the angle sensor 42 can measure the angle between the connecting end 411 of the rocker 41 and the seat back 11, and the host can calculate the user's shoulder height data through the angle between the connecting end 411 and the seat back 11.

[0059] Step 3: Based on the relationship parameters between the human spine curve and the user's shoulder height data, the respective extension amounts of the plurality of backrest extension members 21 arranged longitudinally on the seat back 11 are adjusted to obtain a preset backrest support curvature;

[0060] Step 4, wherein the step of collecting two sets of angle data between the two rockers 41 and the seat back 11 respectively through the two angle sensors 42 includes: obtaining the difference between the two sets of angle data of the two angle sensors 42 to obtain the shoulder height deviation value; if the shoulder height deviation value is greater than the preset deviation threshold, a user scoliosis prompt is issued.

[0061] In summary, the present application provides a new type of sitting posture correction chair and sitting posture correction method. This solution can adjust the backrest telescopic member 21 on the seat back 11 according to the user's shoulder height, so that the support of the seat back 11 can be adjusted to a standard support arc, so that the sitting posture correction chair can be adapted to users of different heights, and the sitting posture correction effect is more accurate. Then, the air pressure sensor 221 of the backrest airbag 22 is used to detect whether the user's sitting posture is standard. In addition, this solution can also measure the height difference between the left and right shoulders of the user through the height measuring device 4 to evaluate the user's scoliosis.

[0062] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
