DETAILED DESCRIPTION

[0031] The following describes the embodiments of the present application through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the features in the following embodiments can be combined with each other unless they conflict.

[0032] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the figures only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0033] In the following description, a number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is apparent to those skilled in the art that the embodiments of the present application can be practiced without these specific details. In the following embodiments, well-known structures and devices are shown in the form of block diagrams to avoid obscuring the embodiments of the present application.

[0034] Traditional seats are unable to provide personalized spinal correction support, which leads to the driver and passengers in driving scenarios being prone to incorrect sitting postures during long rides, which in turn causes damage to the spine. In office scenarios, workers who sit in office chairs for long periods of time are also prone to incorrect sitting postures, which in turn causes damage to the spine. The present application is intended to solve the technical problem that traditional seats are unable to provide personalized spinal correction support, which leads to people being prone to incorrect sitting postures during long rides, which in turn causes damage to the spine. The following describes an embodiment of the present application using a vehicle-mounted spinal correction seat as an example.

[0035] Referring to FIG1 , the vehicle-mounted spinal correction seat provided by the present application includes: a seat body 1, which includes a seat cushion 11, a backrest 12, a headrest 13, and a lumbar support 14, wherein the seat cushion 11, the backrest 12, the headrest 13, and the lumbar support 14 are adjustable; an infrared scanning device 2, which includes a plurality of infrared scanning points 21, which are installed on the backrest 12 and located on the side of the backrest 12 corresponding to the passenger's back to scan the passenger's spine; and a data processing device 3, which is electrically connected to the infrared scanning device 2, the seat cushion 11, the backrest 12, the headrest 13, and the lumbar support 14, respectively, to adjust the seat cushion 11, the backrest 12, the headrest 13, and the lumbar support 14 accordingly according to the spinal shape obtained by the scan. The infrared scanning device 2 can be an infrared scanner, and the data processing device 3 can be one or more processors.

[0036] From the above, it's easy to see that the seat body 1 can be a driver's seat, a passenger seat, or a rear seat. While a passenger is seated in a vehicle, their back will be aligned with the infrared scanning device 2 on the backrest 12. The infrared scanning device 2 uses multiple infrared scanning points 21 arranged on the backrest 12 to scan the spine in the middle area of ​​the passenger's back. Simulation technology is then used to accurately capture a three-dimensional image of the human back and automatically identify the spinal morphology. If the spinal morphology deviates from the standard, the data processing device 3 controls the backrest 12, headrest 13, and lumbar support 14 and makes corresponding adjustments. Consequently, by adjusting the backrest 12, headrest 13, and lumbar support 14, the spinal morphology can be maintained within the standard range, thereby correcting the sitting posture. The infrared scanning points 21 are located on the side of the backrest 12 where the passenger leans, facilitating spinal scanning after the passenger sits down. When adjusting the backrest 12, headrest 13, and lumbar support 14, the adjustment methods of each component correspond to the spinal morphology correction method. For example, when adjusting the backrest 12, in order to correct the scoliosis angle, the backrest 12 will be adjusted in the direction of the corrected scoliosis angle. For example, if the scoliosis angle is toward the left or right side of the seat body 1, the backrest 12 will be adjusted to the right or left. If the scoliosis angle is toward the back of the seat body 1, the backrest 12 will be adjusted forward. When adjusting the headrest 13, if it is detected that the thoracic curvature angle exceeds the standard shape, the headrest 13 will be controlled to adjust forward and backward. When adjusting the lumbar support 14, the lumbar support 14 can be corrected and adjusted in the opposite direction of the curvature angle, rotation angle, and inclination angle based on the curvature angle of the lumbar curvature, the rotation angle of the pelvic rotation angle, and the inclination angle of the pelvic tilt angle. By using the seat to correct the spine as described above, it is possible to scan the passenger's spine without radiation and accurately measure the shape of the spine. The seat back 12, headrest 13 and lumbar support 14 are adjusted separately according to the shape of the spine to ensure that the passenger's spine shape remains within the standard shape range when sitting on the seat, so that the passenger can sit on the seat without injury.

[0037] As shown in FIG1 , the seat further comprises: a switch button 4 mounted on the seat body 1 , the switch button 4 being electrically connected to the infrared scanning device 2 to control the infrared scanning device 2 to be turned on or off.

[0038] In one embodiment of the present application, the switch button 4 can be installed on the backrest 12, or it can be installed in other areas of the seat that are convenient for hand touch, so that the infrared scanning device 2 can be activated by pressing the switch button 4 to scan the spine of the human back through the infrared scanning point 21.

[0039] Similarly, a control signal may be sent to the infrared scanning device 2 via a remote controller or a vehicle computer, so as to realize the opening control of the infrared scanning device 2 .

[0040] The infrared scanning points 21 are arranged in a plurality of groups along the length direction of the spine of the passenger's back, and the infrared scanning points 21 in each group are distributed on both sides of the spine of the passenger's back.

[0041] In one embodiment of the present application, when scanning a passenger's spine, to ensure that the human spine is scanned along its length, the infrared scanning points 21 are arranged along the length of the spine. Furthermore, to better measure the morphology of the left and right sides of the spine, the infrared scanning points 21 are distributed on both sides of the spine. For example, the infrared scanning points 21 are composed of four, wherein two rows of infrared scanning points 21 are distributed along the length of the spine, with each row containing two infrared scanning points 21. Each row of infrared scanning points 21 forms a sector-shaped scanning area corresponding to the length of the spine, and the sector-shaped scanning area of ​​the corresponding column constitutes a scan of both sides of the spine.

[0042] As an optional embodiment of the present invention, after the driver or passenger enters the vehicle, they press and hold the power button for three seconds to activate the system. This activates the infrared scanning point 21, which scans for 20 seconds. The data processing device 3 then generates a three-dimensional image and analyzes the spinal morphology upon receiving the scan data. Within 30 seconds, the device automatically adjusts the angles of the headrest 13, lumbar support 14, and backrest 12 based on the passenger's condition.

[0043] As shown in Figure 2, the data processing device 3 provided in the embodiment of the present application includes: a spine scanning unit 5, which is configured to control the infrared scanning device 2 to collect scanning data of the spine. For example, the spine scanning unit 5 can control the opening and closing of the infrared scanning device 2, or configure the working cycle of the infrared scanning device 2; a data calculation unit 6, which is configured to determine the degree of curvature of each area of ​​the spine based on the scanning data; and a seat adjustment unit 7, which is communicated with the data calculation unit 6 and is configured to determine whether the degree of curvature of each area of ​​the spine meets the corresponding predetermined requirements of each area. If the predetermined requirements are not met, the headrest 13, lumbar support 14 and backrest 12 are controlled to be adjusted accordingly to correct the spine.

[0044] In one embodiment of the present application, when scanning the spine, measuring the degree of curvature, and adjusting the seat, the spine scanning unit 5 can use the infrared scanning point 21 to scan the back, collect the scanning data, and transmit the scanning data to the data calculation unit 6. After obtaining the scanning data, the data calculation unit 6 can calculate the degree of curvature of each area corresponding to the spine. After calculating the degree of curvature of each area of ​​the spine, the data calculation unit 6 can transmit the degree of curvature of each area of ​​the spine to the seat adjustment unit 7. The seat adjustment unit 7 determines whether the degree of curvature of each area exceeds the predetermined requirements set for each area. If it exceeds the predetermined requirements, it means that the back spine needs to be corrected, and the seat is controlled and adjusted according to the degree to which the curvature exceeds the preset requirements. Therefore, the passenger's spinal morphology can be corrected by adjusting the seat, thereby ensuring the passenger's sitting posture and reducing spinal injuries.

[0045] As shown in Figure 3, data calculation unit 6 includes a repository 61 and a comparison and analysis module 62. The architecture repository 61 stores the standard spine morphology in the human body database architecture. The comparison and analysis module 62 compares the spine morphology corresponding to the scan data with the standard spine morphology in the human body database architecture to determine the curvature of the current spine relative to the standard spine.

[0046] In one embodiment of the present invention, when determining the degree of spinal curvature, the data calculation unit 6 utilizes the architecture repository 61 to store a human database architecture consisting of standard spines. Furthermore, when the spine is scanned and the scan data is obtained, the comparison and analysis module 62 automatically compares and analyzes the spine scan data with the standard spine to determine the differences between the spine corresponding to the scan data and the standard spine, and also determines the degree of curvature of the spine corresponding to the scan data relative to the standard spine.

[0047] Furthermore, the comparison and analysis module 62 includes a partition comparison module 621 and a curvature calculation module 622. The partition comparison module 621 compares the 3D images of each spinal region corresponding to the scan data with the 3D images of each corresponding region of the standard spine. The curvature calculation module 622 calculates the curvature angle of each spinal region relative to the corresponding region of the standard spine.

[0048] In one embodiment of the present application, when determining the degree of curvature of the spine corresponding to the scan data relative to the standard spine, the seat adjustment method corresponding to the deformation is different according to the difference in each area of ​​the spine. Therefore, when performing comparative analysis, it is necessary to perform separate comparative analysis of each area of ​​the spine. Specifically, after scanning the spine to obtain three-dimensional images of each area of ​​the spine, the partition comparison module 621 can be used to perform separate morphological comparisons between the three-dimensional images of each area of ​​the spine corresponding to the scan data and the three-dimensional images of each corresponding area of ​​the standard spine. The curvature degree calculation module 622 can then be used to calculate the curvature angle of each area of ​​the spine corresponding to the scan data relative to the standard spine. In other words, the curvature angle of each area of ​​the spine relative to each corresponding area of ​​the standard spine is the portion of the curvature angle of the spine corresponding to the scan data that exceeds the angle range of the standard curvature angle of the standard spine.

[0049] It is worth noting that the scanned spine is a three-dimensional image of a portion of the spine obtained by preliminary scanning at the infrared scanning point 21. The scanned data is then compared and calculated by the data calculation unit 6 with the morphology of a standard spine to obtain a standardized three-dimensional image of the spine corresponding to the scanned spine and including all regions of the spine. The three-dimensional image of the spine including all regions of the spine is then compared with the curvature of the standard spine.

[0050] The curvature angles include scoliosis angle, thoracic curvature angle, lumbar curvature angle, pelvic rotation angle and pelvic tilt angle.

[0051] In one embodiment of the present application, the scoliosis angle refers to the overall scoliosis angle, meaning that the spine, originally straight, bends to the left or right when seated. The thoracic curve, lumbar curve, and pelvis are arranged in order from top to bottom along the height of the spine. This allows the backrest 12 to be adjusted based on the scoliosis angle, and the headrest 13 to be adjusted based on the thoracic curve angle. The lumbar support 14 can be adjusted in height, angle, and position based on the lumbar curve angle, pelvic rotation angle, and pelvic tilt angle.

[0052] As shown in Figure 4, the seat adjustment unit 7 includes a data output module 71 and an adjustment control module 72. The data output module 71 outputs a judgment signal when it determines that the curvature of each spinal region does not meet the corresponding predetermined requirements. Based on the judgment signal, the adjustment control module 72 controls the seat to make negative adjustments to the corresponding region, reducing the curvature.

[0053] In one embodiment of the present application, when adjusting the seat based on the degree of spinal curvature, the data output module 71 may output a determination signal indicating non-satisfaction to the adjustment control module 72 if the degree of curvature in various regions of the spine does not meet the corresponding preset requirements. Based on the determination signal, the adjustment control module 72 adjusts the seat to reduce the degree of curvature in the region where the determination signal was generated, thereby correcting the corresponding region of the spine.

[0054] Furthermore, the adjustment control module 72 includes a backrest adjustment module 721, a headrest adjustment module 722, and a lumbar support adjustment module 723. The backrest adjustment module 721 adjusts the backrest 12 in the opposite direction (the same angle as the first angle difference) based on a first angle difference and bending direction between the scoliosis angle and the standard scoliosis angle. The headrest adjustment module 722 adjusts the headrest 13 in the opposite direction (the same angle as the second angle difference) based on a second angle difference and bending direction between the thoracic curve angle and the standard thoracic curve angle. The lumbar support adjustment module 723 is configured to adjust the lumbar support 14 in the opposite direction (the same angle as the third, fourth, and fifth angle differences) based on a third angle difference and bending direction between the lumbar curve angle and the standard lumbar curve angle, a fourth angle difference and bending direction between the pelvic rotation angle and the standard pelvic rotation angle, and a fifth angle difference and bending direction between the pelvic tilt angle and the standard pelvic tilt angle. The opposite direction is a direction that weakens or strengthens the curve. For example, when the scanned bending angle is greater than the standard spine angle, the opposite direction is a direction of reducing the bending; when the scanned bending angle is less than the standard spine angle, the opposite direction is a direction of increasing the bending.

[0055] In one embodiment of the present application, when controlling and adjusting the seat, the backrest adjustment module 721 may control the backrest 12 to adjust in the direction opposite to the curvature when a first angle difference between the scoliosis angle and the standard scoliosis angle exceeds a predetermined requirement, thereby correcting the scoliosis angle and keeping the scoliosis angle within the standard scoliosis angle range. The headrest adjustment module 722 may control the headrest 13 to adjust in the direction opposite to the direction of reducing the thoracic curvature angle when a second angle difference between the thoracic curvature angle and the standard thoracic curvature angle exceeds a predetermined requirement, thereby correcting the thoracic curvature angle and keeping the thoracic curvature angle within the standard thoracic curvature angle range. When the lumbar flexion angle, pelvic rotation angle and pelvic tilt angle exceed the third angle difference, fourth angle difference and fifth angle difference of the predetermined requirements respectively, the lumbar support adjustment module 723 controls the lumbar support 14 to adjust in the opposite direction of weakening the lumbar flexion angle, pelvic rotation angle and pelvic tilt angle, so as to correct the lumbar flexion angle, pelvic rotation angle and pelvic tilt angle, and keep the lumbar flexion angle, pelvic rotation angle and pelvic tilt angle within the range of the lumbar flexion angle, pelvic rotation angle and pelvic tilt angle corresponding to the standard form.

[0056] Among them, the first angle difference is the difference between the scoliosis angle of the scanned spine and the scoliosis angle of the standard spine. The second angle difference is the difference between the thoracic curvature angle of the scanned spine and the thoracic curvature angle of the standard spine. The third angle difference is the difference between the lumbar curvature angle of the scanned spine and the lumbar curvature angle of the standard spine. The fourth angle difference is the pelvic rotation angle that exceeds the pelvic rotation angle of the standard spine. The fifth angle difference is the angle difference when the pelvic tilt angle exceeds the pelvic tilt angle of the standard spine.

[0057] Specifically, when the scoliosis angle is corrected, the angle of the backrest 12 is adjusted accordingly. For example, when the spine detects that the left curvature is 5 degrees greater than the scoliosis angle of the standard spine, the backrest adjustment module 721 controls the back angle of the backrest 12 to be adjusted 5 degrees to the right; when the spine bends backward and is 3 degrees greater than the scoliosis angle of the standard spine, the backrest adjustment module 721 controls the back angle of the backrest 12 to be adjusted forward by 3 degrees. When the thoracic curvature angle is corrected, the angle of the headrest 13 is adjusted accordingly. For example, when the spine detects that the thoracic curvature angle is 2 degrees greater than the thoracic curvature angle of the standard spine, the headrest adjustment module 722 controls the headrest 13 to be adjusted backward by 2 degrees. When the lumbar curvature angle, pelvic rotation angle and pelvic tilt angle are corrected, the angle of the lumbar support 14 is adjusted accordingly. For example, the third angle difference, fourth angle difference and fifth angle difference of the lumbar flexion angle, pelvic rotation angle and pelvic tilt angle are detected, and according to the third angle difference, fourth angle difference and fifth angle difference, the lumbar support adjustment module 723 controls the equal adjustment of the height, angle and position of the lumbar support 14.

[0058] Referring to Figure 5 , the human spine is composed of the cervical curve, thoracic curve, lumbar curve, and sacral curve. The thoracic curve corresponds to the thoracic curve angle, the lumbar curve corresponds to the lumbar curve angle, and the sacral curve corresponds to the pelvic rotation angle and pelvic tilt angle. The entire spine corresponds to the scoliosis angle. When adjusting the seat, the scoliosis angle is corrected via the backrest adjustment module 721, the thoracic curve angle is corrected via the headrest adjustment module 722, and the lumbar curve angle, pelvic rotation angle, and pelvic tilt angle are adjusted via the lumbar support adjustment module 723.

[0059] Please refer to Figure 6, which shows three groups of side views of the top of the pelvis, namely "normal", "posterior tilt" and "anterior tilt". When the pelvis is in the "normal" shape, the arc of the top of the pelvis is located in the middle position, while when the pelvis is "posterior tilt", the arc of the top of the pelvis is offset to the left, and when the pelvis is "anterior tilt", the arc of the top of the pelvis is offset to the right. The pelvic tilt angle is the tilt angle of the pelvis when it tilts forward or backward. Figure 6 also shows four groups of frontal views of the bottom of the pelvis, which are different heights of the left and right pelvis and the pelvis rotated to the left / right. Among them, when the left and right heights of the pelvis are different, the left side will be lower and the right side will be higher, or the left side will be higher and the right side will be lower. When the pelvis rotates to the left / right, there will be clockwise deflection of the pelvis and counterclockwise deflection of the pelvis. The pelvic rotation angle is the angle of rotation of the pelvis left and right.

[0060] The lumbar flexion angle, pelvic rotation angle and pelvic tilt angle are adjusted by the lumbar support adjustment module 723. Specifically, when the lumbar flexion angle is greater than the lumbar flexion angle of the standard spine by 3 degrees, the lumbar support 14 is adjusted to move backward as a whole until the lumbar flexion angle is equal to the lumbar flexion angle of the standard spine; when the pelvic tilt angle is greater than the pelvic tilt angle of the standard spine, for example, when it is tilted forward by 5 degrees, the lumbar support 14 is adjusted to rotate backward by 5 degrees; when the pelvic rotation angle is lower on the left and higher on the right, for example, when it is rotated 3 degrees to the left, the lumbar support 14 is adjusted to rotate 3 degrees to the right.

[0061] Please refer to Figure 7 for the corresponding morphology of the spine when scoliosis occurs, that is, the corresponding scoliosis angle. The leftmost image shows the "C" shape formed by the spine when scoliosis occurs, the middle image shows the "S" shape formed by the spine when scoliosis occurs, and the rightmost image shows the normal morphology of the spine, which corresponds to the standard spinal shape.

[0062] As shown in FIG8 , the present application further provides a vehicle-mounted spinal correction method, comprising the following steps:

[0063] S1: Collecting spinal scan data using an infrared scanning device;

[0064] S2: Determine the degree of curvature of each region of the spine based on the scan data; and

[0065] S3: Determine whether the curvature of each region of the spine meets the corresponding predetermined requirements of each region. If it does not meet the predetermined requirements, control the seat to adjust to correct the spine.

[0066] In one embodiment of the present application, when the spine is corrected through seat adjustment, the human spine is scanned according to the infrared scanning point 21 to obtain scanning data of the spine. And based on this scanning data, the degree of curvature of each region of the spine, including the scoliosis angle, thoracic curvature angle, lumbar curvature angle, pelvic rotation angle and pelvic tilt angle, is measured. And it is determined whether the degree of curvature exceeds the predetermined requirements of each region corresponding to the standard spine. In order to achieve, when the predetermined requirements are not met, the seat backrest 12, headrest 13 and lumbar support 14 corresponding to each region of the spine are adjusted respectively, so that each region of the spine is corrected to the standard shape, thereby protecting the human spine when riding in a car seat.

[0067] In summary, the present application utilizes an infrared scanning device 2 and the arrangement of its included infrared scanning points 21 on the backrest 12 to enable radiation-free scanning of a passenger's spine using infrared technology and accurately measure the degree of spinal curvature. Furthermore, when measuring the degree of spinal curvature, by calculating whether the scanned spinal curvature exceeds the predetermined requirements corresponding to the standard spine, it can be determined whether the spine should be corrected through seat adjustment. Furthermore, when adjusting the seat, by measuring various regions of the spine, such as the scoliosis angle, thoracic curvature angle, lumbar curvature angle, pelvic rotation angle, and pelvic tilt angle, it is possible to adjust the seat cushion 11, backrest 12, headrest 13, and lumbar support 14 of the seat body 1 in a regional manner. The adjusted angles of the backrest 12, headrest 13, and lumbar support 14 provide a seating posture that is suitable for the passenger's spine, reducing damage to the spine when riding in a car seat, and providing an ergonomic and non-injurious sitting posture correction experience. Therefore, the present application effectively overcomes various shortcomings of some seats and has high industrial application value.
