[0021] Reference below Figure 1 A seat adjustment system according to an embodiment of the present invention is described.

[0022] A seat adjustment system according to an embodiment of the first aspect of the present invention includes: an image acquisition and processing device and a seat assembly.

[0023] The image acquisition and processing device includes an image acquisition module and a data processing module. The image acquisition module is used to obtain a sitting image of the user's upper body. The data processing module is electrically connected to the image acquisition module.

The key points of the human body include at least one of the shoulder key points, elbow key points, waist key points, and head key points. The sitting status data includes at least one of the forward and backward leaning angles, the side sitting offset, and the body tilt angle.

[0024] For example, the image acquisition and processing device can be installed on a desktop.

[0025] For example, the image acquisition module may be a camera.

[0026] For example, the human body key points include two shoulder key points, and the positions of the two shoulder key points are respectively the positions of the left shoulder and the right shoulder.

[0027] For example, the human body key points include two elbow key points, and the positions of the two elbow key points are respectively the positions of the left elbow and the right elbow.

[0028] For example, the key points of the human body include a waist key point, and the position of the waist key point is the center position of the user's waist in the left and right directions.

[0029] For example, the human body key points include a head key point, and the position of the head key point is the center point of the sphere where the user's head is located.

[0030] For example, the forward and backward leaning angle is the angle between the line connecting the midpoint of the line segment between the two shoulder key points and the coordinates of the waist key point and the vertical direction; the coordinates of the standard position of the head key point are set inside the data processing module, and the side sitting offset is the distance between the head key point and the standard position of the head key point in the left and right directions; the body tilt angle is the angle between the line connecting the two shoulder key points and the horizontal direction.

[0031] By having the data processing module extract the coordinates of key points of the human body based on the sitting image obtained by the image acquisition module, and calculating the user's sitting status data based on the coordinates of the key points of the human body, the data processing module can more accurately determine the user's sitting posture vital signs data, improve the comprehensiveness and accuracy of the data processing module's monitoring of the user's vital signs data, and improve the accuracy of sitting posture judgment.

[0032] The seat assembly includes a seat body, a support assembly and a seat adjustment assembly. The support assembly and the seat adjustment assembly are both arranged on the seat body. The support assembly is used to contact the human body and support the key points of the human body. The seat adjustment assembly is connected to the support assembly for adjusting the support assembly. The seat adjustment assembly is electrically connected to the data processing module and is used to adjust the support assembly according to the sitting status data.

[0033] By having the seat adjustment component adjust the support component according to the sitting posture data, the support component can be automatically adjusted according to the user's sitting posture, thereby improving the matching degree between the seat and the user's sitting posture and alleviating the user's health problems caused by sitting for a long time.

[0034] According to the seat adjustment system of an embodiment of the present invention, by enabling the data processing module to extract the coordinates of the key points of the human body based on the sitting posture image obtained by the image acquisition module, and calculating the user's sitting posture status data based on the coordinates of the key points of the human body, the data processing module can more accurately determine the user's sitting posture vital signs data, thereby improving the comprehensiveness and accuracy of the data processing module's monitoring of the user's vital signs data and improving the accuracy of sitting posture judgment; by enabling the seat adjustment component to adjust the support component according to the sitting posture status data, the support component can be automatically adjusted according to the user's sitting posture, thereby improving the matching degree between the seat and the user's sitting posture, and alleviating the user's health problems caused by sitting for a long time.

[0035] According to some embodiments of the present invention, the support assembly includes at least one of a lumbar support, lumbar support wings, a headrest, and an armrest, and the seat adjustment assembly includes at least one of a lumbar support adjustment unit, a lumbar support wing adjustment unit, a headrest adjustment unit, and an armrest adjustment unit;

[0036] The lumbar support adjustment unit is connected to the lumbar support and is used to drive the lumbar support to move according to the sitting posture status data. The lumbar support side wing adjustment unit is connected to the lumbar support side wing and is used to drive the lumbar support side wing to rotate according to the sitting posture status data. The headrest adjustment unit is connected to the headrest and is used to drive the headrest to rotate or move according to the sitting posture status data. The armrest adjustment unit is connected to the armrest and is used to drive the armrest to move according to the seat status data.

[0037] For example, the chair body includes a seat and a backrest. The lumbar support is located in the center of the front of the backrest. The two lumbar support wings are rotatably connected to the two sides of the lumbar support. The lumbar support and the lumbar support wings are designed to contact the user's waist. The headrest is located at the upper front of the backrest and is designed to contact the user's head. There are two armrests, one on the left and right sides of the chair body, and the armrests are designed to contact the user's left and right arms.

[0038] By enabling the lumbar support adjustment unit to drive the movement of the lumbar support based on sitting posture data, the lumbar support can be more closely aligned with the user's sitting posture, providing more support for the user's lumbar region, improving lumbar comfort, and alleviating health issues associated with prolonged sitting. By enabling the lumbar support wing adjustment unit to drive the rotation of the two lumbar support wings based on sitting posture data, the lumbar support wings can be more closely aligned with the user's sitting posture, providing more support for the user's lumbar region, improving lumbar comfort, and alleviating health issues associated with prolonged sitting. By enabling the headrest adjustment unit to drive the movement of the headrest based on sitting posture data, the headrest can be more closely aligned with the user's sitting posture, providing more support for the user's head, improving head and neck comfort, and alleviating health issues associated with prolonged sitting. By enabling the armrest adjustment unit to drive the movement of the armrest based on sitting posture data, the armrest can be more closely aligned with the user's sitting posture, providing more support for the user's arms, improving arm comfort, and alleviating health issues associated with prolonged sitting.

[0039] According to some embodiments of the present invention, the seat body has an interface, the interface is electrically connected to the seat adjustment component, the image acquisition and processing device is connected to a connecting wire, one end of the connecting wire has a connecting terminal, and the connecting terminal is plugged into the interface.

[0040] For example, the lumbar support adjustment unit is electrically connected to the interface; for example, the lumbar support wing adjustment unit is electrically connected to the interface; for example, the headrest adjustment unit is electrically connected to the interface; for example, the armrest adjustment unit is electrically connected to the interface.

[0041] By connecting the image acquisition and processing device with a connecting wire and plugging the connecting terminal of the connecting wire into the interface, the connection between the image acquisition and processing device and the seat can be made more complete.

[0042] According to some embodiments of the present invention, the chair body is provided with a first wireless communication module, and the image acquisition and processing device includes a second wireless communication module, which is adapted to wirelessly connect to the first wireless communication module. By wirelessly connecting the second wireless communication module to the first wireless communication module, the presence of a connecting wire between the chair and the image acquisition and processing device, which could interfere with a user's normal use of the chair, can be avoided.

[0043] Reference Figure 1 According to a control method for a seat adjustment system according to a second embodiment of the present invention, the seat adjustment system is the seat adjustment system according to the first embodiment of the present invention, and the control method for the seat adjustment system includes:

[0044] The image acquisition module obtains the user's upper body image and transmits the image to the data processing module;

[0045] The data processing module extracts the coordinates of key points of the human body based on the sitting posture recognition algorithm;

[0046] The data processing module calculates the sitting posture data based on the coordinates of the key points of the human body;

[0047] The data processing module obtains corresponding adjustment parameters from the adjustment strategy model according to the sitting posture state data and sends the adjustment parameters to the seat adjustment component;

[0048] The seat adjustment component adjusts the support component according to the adjustment parameters to adapt to the current sitting posture of the human body.

[0049] For example, after the image acquisition module transmits the image to the data processing module, the image is subjected to Gaussian filtering and noise reduction processing.

[0050] For example, after the image acquisition module transmits the image to the data processing module, the image is subjected to brightness equalization processing.

[0051] For example, after the image acquisition module passes the image to the data processing module, the area containing the upper body of the user or the head of the user is cropped out based on the Haar cascade detector.

[0052] The data processing module extracts the coordinates of key points of the human body according to the sitting posture recognition algorithm and calculates the sitting posture status data, thereby improving the comprehensiveness and accuracy of the data processing module's monitoring of user vital signs data, improving the accuracy of sitting posture judgment, and making adjustments to the seat based on the judged sitting posture more accurate.

[0053] For example, the coordinates of key points of the human body extracted by the data processing module include: the coordinates of the head key point, the coordinates of the two shoulder key points, the coordinates of the two elbow key points, the coordinates of the waist key point, etc. The sitting posture data calculated by the data processing module includes: forward and backward leaning angle, side sitting offset, and left and right body tilt angle.

[0054] For example, the sitting posture recognition algorithm and the adjustment strategy model are stored in the data processing module.

[0055] By allowing the seat adjustment component to adjust the support component according to the adjustment parameters, the matching degree between the seat and the user's sitting posture can be improved, providing more sufficient support for the user's body, improving the user's comfort, and alleviating the user's health problems caused by sitting for a long time.

[0056] For example, the control method of the seat adjustment system further includes: recording user usage data, and optimizing a mapping table according to the user usage data, recording optimal support parameters for users of different body types.

[0057] According to the control method of the seat adjustment system of an embodiment of the present invention, by enabling the data processing module to extract the coordinates of the key points of the human body according to the sitting posture recognition algorithm, and then calculating the sitting posture status data according to the coordinates of the key points of the human body, the comprehensiveness and accuracy of the data processing module's monitoring of the user's vital signs data are improved, and the accuracy of the sitting posture judgment is improved; by enabling the seat adjustment component to adjust the support component according to the adjustment parameters, the matching degree between the seat and the user's sitting posture can be improved, and the health problems of the user caused by sitting for a long time can be alleviated.

[0058] Reference Figure 1 ,According to some embodiments of the present invention, the data processing module calculates the sitting posture state data according to the coordinates of the key points of the human body, including: judging the sitting posture type according to the sitting posture state data, the sitting posture type including the standard sitting posture and the non-standard sitting posture;

[0059] The seat adjustment component adjusts the support component according to the adjustment parameters to adapt to the current sitting posture of the human body, including:

[0060] When the sitting posture type is determined to be a standard sitting posture, the seat adjustment component controls the support component to maintain the current state;

[0061] When it is determined that the sitting posture type is a non-standard sitting posture, the seat adjustment component drives the support component to adjust the position of the support component.

[0062] For example, the data processing module stores a standard sitting posture range. When the sitting posture status data is within the standard sitting posture range, the user's sitting posture type is judged to be a standard sitting posture, and the seat adjustment component controls the support component to maintain the current state; when the sitting posture status data is outside the standard sitting posture range, the user's sitting posture type is judged to be a non-standard sitting posture, and the seat adjustment component drives the support component to adjust the position of the support component.

[0063] By making the seat adjustment component drive the support component to adjust the position of the support component when the sitting posture type is a non-standard sitting posture, the matching degree between the seat and the user's sitting posture can be improved, providing more sufficient support for the user's body, improving the user's comfort, and alleviating the user's health problems caused by sitting for a long time.

[0064] Reference Figure 1 According to some embodiments of the present invention, non-standard sitting postures include forward leaning sitting posture and backward leaning sitting posture. The user's sitting posture is determined to be forward leaning sitting posture or backward leaning sitting posture according to the forward leaning and backward leaning angles. The support assembly includes a lumbar support, two lumbar support side wings, a headrest and armrests. The two lumbar support side wings are located on the left and right sides of the lumbar support.

[0065] When the user's sitting posture is a forward leaning sitting posture, the lumbar support is controlled to move forward, the expansion angles of the two lumbar support side wings are controlled to increase, and the armrests are controlled to move upward;

[0066] When the user sits in a reclining position, the lumbar support is controlled to move backward, the deployment angles of the two lumbar support side wings are controlled to decrease, the headrest is controlled to move upward, and the armrest is controlled to move downward.

[0067] For example, when the line between the midpoint of the line segment between the two shoulder key points of the user and the coordinates of the waist key points is tilted forward from bottom to top, the user's sitting posture is a forward leaning sitting posture; when the line between the midpoint of the line segment between the two shoulder key points of the user and the coordinates of the waist key points is tilted backward from bottom to top, the user's sitting posture is a backward leaning sitting posture.

[0068] The unfolding angle of the lumbar support side wings refers to the angle between the plane where the part of the lumbar support side wings in contact with the user's body is located and the front-to-back direction.

[0069] For example, the two lumbar support wings are the left lumbar support wing and the right lumbar support wing. The expansion angle of the left lumbar support wing refers to the angle between the plane where the part of the left lumbar support wing that contacts the user's body and the front-to-back direction; the expansion angle of the right lumbar support wing refers to the angle between the plane where the part of the right lumbar support wing that contacts the user's body and the front-to-back direction.

[0070] For example, when the user is leaning forward, the lumbar support moves forward 10-15mm, the lumbar support side wings expand angle 10°-15°, and the armrests move upward 5-8mm according to the forward and backward leaning angles. When the user is leaning back, the lumbar support moves backward 5-10mm, the lumbar support side wings expand angle 10°-15°, and the armrests move downward 3-5mm according to the forward and backward leaning angles.

[0071] When the user is sitting in a forward leaning posture, by controlling the lumbar support to move forward, increasing the expansion angles of the two lumbar support wings, and controlling the armrests to move upward, the lumbar support and the lumbar support wings can be brought closer to the user's waist, providing more sufficient support for the user's waist, and the armrests can be brought closer to the user's elbows and arms, thereby improving the user's comfort. This can improve the matching degree between the chair and the user's sitting posture, and alleviate the user's health problems caused by sitting for long periods of time.

[0072] When the user is sitting in a reclining position, by controlling the lumbar support to move backward, reducing the expansion angles of the two lumbar support wings, controlling the headrest to move upward, and controlling the armrests to move downward, the lumbar support and the lumbar support wings can be brought closer to the user's waist, providing more sufficient support for the user's waist, the headrest can be brought closer to the user's head, providing more sufficient support for the user's head, and the armrests can be brought closer to the user's elbows and arms, thereby improving the user's comfort, improving the matching degree between the seat and the user's sitting posture, and alleviating the user's health problems caused by sitting for long periods of time.

[0073] Reference Figure 1According to some embodiments of the present application, the non-standard sitting posture includes left side sitting and right side sitting, the sitting posture of the user is determined as left side sitting or right side sitting according to the side sitting offset, and the support assembly includes a waist support, a left waist support wing, a right waist support wing, a headrest, a left armrest, and a right armrest.

[0074] When the sitting posture of the user is left side sitting, the deployment angle of the left waist support wing is controlled to increase, the deployment angle of the right waist support wing is controlled to decrease, the headrest is controlled to move leftward, and the left armrest is controlled to move upward;

[0075] When the sitting posture of the user is right side sitting, the deployment angle of the left waist support wing is controlled to decrease, the deployment angle of the right waist support wing is controlled to increase, the headrest is controlled to move rightward, and the right armrest is controlled to move upward.

[0076] For example, the data processing module is internally provided with a coordinate of a standard position of a head key point, when the head key point of the user is located to the left of the standard position of the head key point, the sitting posture of the user is left side sitting, and when the head key point of the user is located to the right of the standard position of the head key point, the sitting posture of the user is right side sitting.

[0077] The deployment angle of the left waist support wing refers to the included angle between the plane where the part of the left waist support wing in contact with the body of the user is located and the front-rear direction, and the deployment angle of the right waist support wing refers to the included angle between the plane where the part of the right waist support wing in contact with the body of the user is located and the front-rear direction.

[0078] For example, when the sitting posture of the user is left side sitting, according to the side sitting offset, the deployment angle of the left waist support wing is controlled to increase by 20°, the deployment angle of the right waist support wing is controlled to decrease by 10°, the headrest is controlled to move leftward by 5-8 mm, and the left armrest is controlled to move upward by 8-10 mm. When the sitting posture of the user is right side sitting, according to the side sitting offset, the deployment angle of the right wing is controlled to increase by 20°, the deployment angle of the left wing is controlled to decrease by 10°, the headrest is controlled to move rightward by 5-8 mm, and the right armrest is controlled to move upward by 8-10 mm.

[0079] When the sitting posture of the user is left side sitting, by controlling the deployment angle of the left waist support wing to increase, the deployment angle of the right waist support wing to decrease, the headrest to move leftward, and the left armrest to move upward, the waist support, the left waist support wing, and the right waist support wing can be made closer to the waist of the user, providing more sufficient support for the waist of the user, the left armrest can be made closer to the elbow and arm of the user, improving the comfort of the user, the matching degree of the seat and the sitting posture of the user can be improved, and the health problems of the user caused by long sitting can be alleviated.

[0080] When the user sits on the right side, by increasing the expansion angle of the right lumbar support wing, decreasing the expansion angle of the left lumbar support wing, controlling the headrest to move to the right, and controlling the right armrest to move upward, the lumbar support, the left lumbar support wing and the right lumbar support wing can be brought closer to the user's waist, providing more adequate support for the user's waist, and the right armrest can be brought closer to the user's elbow and arm, thereby improving the user's comfort, improving the matching degree between the seat and the user's sitting posture, and alleviating the user's health problems caused by sitting for long periods of time.

[0081] Reference Figure 1 According to some embodiments of the present invention, the non-standard sitting posture includes left leaning and right leaning, and the user's sitting posture is determined to be left leaning or right leaning according to the body inclination angle, and the support assembly includes a lumbar support, a left lumbar support side wing, a right lumbar support side wing, a headrest, a left armrest and a right armrest.

[0082] When the user's sitting posture is tilted to the left, the lumbar support is controlled to move upward, the expansion angle of the left lumbar support wing is controlled to increase, the headrest is controlled to tilt to the left, and the left armrest is controlled to move forward;

[0083] When the user's sitting posture is tilted to the right, the lumbar support is controlled to move upward, the deployment angle of the right lumbar support side wing is controlled to increase, the headrest is controlled to tilt to the right, and the right armrest is controlled to move forward.

[0084] For example, when the line between the two shoulder key points of the user is offset toward the left in the direction from top to bottom, the user's sitting posture is left-leaning; when the line between the two shoulder key points of the user is offset toward the right in the direction from top to bottom, the user's sitting posture is right-leaning.

[0085] The deployment angle of the left lumbar support wing refers to the angle between the plane where the left lumbar support wing contacts the user's body and the front-to-back direction. The deployment angle of the right lumbar support wing refers to the angle between the plane where the right lumbar support wing contacts the user's body and the front-to-back direction. The tilt direction of the headrest refers to the angle between the plane where the headrest contacts the user's head and the left-to-right direction.

[0086] For example, when the user is sitting with their body tilted to the left, the lumbar support is controlled to move upward by 8-12mm, the left wing's deployment angle is increased by 15°, the headrest is controlled to tilt 5° to the left, and the left armrest is controlled to move forward by 5-8mm. For example, when the user is sitting with their body tilted to the right, the right lumbar support wing is controlled to move upward by 8-12mm, the right wing's deployment angle is increased by 15°, the headrest is controlled to tilt 5° to the right, and the right armrest is controlled to move forward by 5-8mm.

[0087] When the user's sitting posture is tilted to the left, the lumbar support can move upward, which can drive the left lumbar support side wing to move upward. The deployment angle of the left lumbar support side wing increases, the headrest tilts to the left, and the left armrest moves forward. The lumbar support and the left lumbar support side wing can be brought closer to the user's waist, providing more adequate support for the user's waist, bringing the headrest closer to the user's head, and bringing the left armrest closer to the user's elbow and arm, thereby improving the user's comfort, improving the matching degree between the seat and the user's sitting posture, and alleviating the user's health problems caused by sitting for long periods of time.

[0088] When the user's sitting posture is tilted to the right, the lumbar support can move upward, which can drive the right lumbar support side wing to move upward. The deployment angle of the right lumbar support side wing increases, the headrest tilts to the right, and the right armrest moves forward. The lumbar support and the right lumbar support side wing can be brought closer to the user's waist, providing more adequate support for the user's waist, bringing the headrest closer to the user's head, and bringing the right armrest closer to the user's elbow and arm, thereby improving the user's comfort, improving the matching degree between the seat and the user's sitting posture, and alleviating the user's health problems caused by sitting for long periods of time.

[0089] According to some embodiments of the present invention, a reminder signal is sent when the sitting posture state data exceeds the sitting posture deviation threshold and the duration exceeds a set time. By sending a reminder signal when the sitting posture state data exceeds the sitting posture deviation threshold and the duration exceeds the set time, the user can be reminded to maintain a non-standard sitting posture for a long time, thereby alleviating the health problems caused by prolonged sitting.

[0090] For example, the reminder signal may include a vibration or a voice prompt.

[0091] According to some embodiments of the present invention, when the sitting posture state data exceeds the sitting posture deviation threshold and the duration exceeds the set time, sending a reminder signal includes:

[0092] When the sitting posture data satisfies at least one of the following conditions: the forward leaning angle exceeds the first set angle, the side sitting offset exceeds the first set offset, and the body tilt angle exceeds the second set angle, and the duration exceeds the set time, a reminder signal is sent;

[0093] The sitting posture offset threshold includes: a first set angle, a first set offset, and a second set angle.

[0094] For example, the first set angle may be 10°, the first set offset may be 10 centimeters, the second set angle may be 15°, and the set time may be 15 minutes.

[0095] For example, when the user's sitting posture satisfies the condition where the forward and backward leaning angles exceed 10 degrees and the duration exceeds 15 minutes, a reminder signal is sent.

[0096] For another example, when the user's sitting posture satisfies the condition that the side sitting offset exceeds 10 centimeters and lasts for more than 15 minutes, a reminder signal is sent.

[0097] For another example, when the user's sitting posture satisfies the condition where the body tilt angle exceeds 15° and lasts for more than 15 minutes, a reminder signal is sent.

[0098] By sending a reminder signal when the sitting posture data meets at least one of the following conditions: the forward and backward leaning angle exceeds the first set angle, the side sitting offset exceeds the first set offset, and the body tilt angle exceeds the second set angle, and the duration exceeds the set duration, the user can be reminded to maintain a non-standard sitting posture for a long time, thereby alleviating the user's health problems caused by long-term sitting.
