[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] Reference below Figure 1 A seat 100 according to an embodiment of a first aspect of the present invention is described.

[0032] like Figure 1 As shown, the seat 100 according to the first embodiment of the present invention includes: a main body, a weight detection module 8, a sitting posture detection module 9, a damping member, a driving member and a control module 10.

[0033] Specifically, the weight detection module 8 is arranged on the main body, and is used to obtain the user's weight information. The sitting posture detection module 9 is arranged on the main body, and is used to obtain the user's sitting posture information. The damping element is arranged on the main body, and the damping element is electrically connected to the control module 10. The driving element is arranged on the main body, and is used to adjust the damping element. The control module 10 is arranged on the main body, and is electrically connected to the weight detection module 8, the sitting posture detection module 9, the damping element and the driving element.

[0034] It can be understood that the main body is the basic structure of the seat 100. The weight detection module 8 measures the weight of the user sitting on the chair through the built-in weight sensor. The user's weight information is very important for the subsequent adjustment of the damping. Different weights require different degrees of support. The sitting posture detection module 9 can be implemented through a pressure distribution sensor or image recognition technology. Understanding how users distribute their weight and the position of their bodies helps to further optimize the support results. The damping member controls the amount of resistance encountered when the chair back tilts backward. The drive member is used to adjust the resistance of the damping member. The control module 10 receives information and makes decisions based on a preset algorithm, and then sends instructions to the drive member to perform corresponding actions.

[0035] In addition, the control module 10 may also have a user interface function, allowing the user to directly input the user's preference settings or other relevant information.

[0036] Existing seats cannot automatically adjust the reclining damping according to the user's weight, which may cause inconvenience in use or affect the comfort and safety of the seat. The seat 100 according to the embodiment of the present invention not only improves the comfort of the user, but also helps to promote healthy work or study habits, reduce back or waist pain caused by long-term poor posture and other problems, and ensures the reclining safety of the seat 100, thereby improving the overall safety factor of the seat 100.

[0037] In some embodiments of the present invention, the seat 100 further includes: an accelerometer 11, which is arranged on the main body and is used to obtain acceleration information of the user during the process of leaning back, and the accelerometer 11 is electrically connected to the control module 10. That is, the accelerometer 11 is installed on the seat 100 to monitor the acceleration changes of the user during the process of leaning back, which can help the control module 10 better understand the dynamic behavior of the user and make corresponding adjustments. For example, when the user leans back quickly, the control module 10 can quickly increase the damping force through the detected acceleration information to prevent excessively fast movements from causing potential safety problems.

[0038] Then, the accelerometer 11 is provided to further enhance the functionality and user experience of the chair 100, improve the intelligence of the chair 100, and significantly improve the comfort and safety of the user. At the same time, for the slow reclining action, the resistance can be appropriately reduced, so that the user feels more natural and smooth.

[0039] In some embodiments of the present invention, the main body includes: a base component 1, a backrest component 2 and a head support component 3, a weight detection module 8 is arranged on the base component 1 to obtain weight information, the backrest component 2 is connected to the base component 1, and the backrest component 2 can be adjusted relative to the base component 1, an accelerometer 11 is at least arranged on the backrest component 2 to obtain acceleration information, the head support component 3 is connected to the backrest component 2, and a sitting posture detection module 9 is at least arranged on the head support component 3 to obtain sitting posture information. Thus, not only the basic body support needs are taken into account, but also the functionality of the seat 100 is enhanced through intelligent technology, so that it can adapt to the personalized needs of different body shapes, preferences and usage scenarios.

[0040] In some embodiments of the present invention, the main body further includes: a chair leg 4 and a lumbar support assembly 5, the base assembly 1 is arranged on the chair leg 4, the lumbar support assembly 5 is located between the backrest assembly 2 and the base assembly 1, and the lumbar support assembly 5 is used to support the user's waist. In other words, the chair leg 4 provides basic support for the entire chair 100 to ensure the stability of the chair 100, the lumbar support assembly 5 is used to support the user's waist and reduce the discomfort caused by sitting for a long time, and an accelerometer 11 can also be set on the lumbar support assembly 5 to cooperate with the accelerometer 11 on the backrest assembly 2 to obtain more accurate acceleration information.

[0041] Furthermore, the main body also includes: an armrest assembly 6 and a leg rest assembly 7. The armrest assembly 6 is provided on the main body and is located on both sides of the width direction of the base assembly 1, and is used to support the user's arms. The leg rest assembly 7 is rotatably connected to the base assembly 1, and the leg rest assembly 7 and the backrest assembly 2 are arranged at intervals in the front-to-back direction of the base assembly 1. In other words, the armrest assembly 6 provides arm support, helps maintain a correct sitting posture, and relieves pressure on the shoulders and neck. A sitting posture detection module 9 can also be provided on the armrest assembly 6, and cooperates with the sitting posture detection module 9 on the headrest assembly 3 to obtain more accurate user sitting posture information. The leg rest assembly 7 supports the user's calves, especially to improve leg comfort when resting. The leg rest assembly 7 is rotatably connected to the base assembly 1 and can be folded up when not in use to save space. As a result, multiple components cooperate with each other to improve the user's comfort and help prevent various health problems caused by poor sitting posture.

[0042] Preferably, the weight detection module 8 is a pressure sensor, and may include multiple ones.

[0043] Preferably, the sitting posture detection module 9 is a camera device or a pressure sensor, or a combination of a camera device and a pressure sensor.

[0044] Preferably, the control module 10 is a single chip microcomputer.

[0045] Furthermore, the chair 100 further includes: a heart rate monitoring module, which is arranged on the main body and is used to obtain the user's real-time heart rate information, and the heart rate monitoring module is electrically connected to the control module 10. That is to say, the heart rate monitoring module can be arranged in the head support component 3, the armrest component 6 or any other position that is easy to contact the skin and can reliably read the heart rate signal. The heart rate monitoring module can be a photoelectric sensor (such as PPG photoplethysmography) or other non-invasive technology to monitor the heart rate. Thus, the overall user experience is improved.

[0046] In some embodiments of the present invention, the chair 100 further includes an adjusting member and a resetting member, wherein the adjusting member is disposed on the main body to adjust the relative height and relative angle between the main body and the horizontal plane, and the resetting member is disposed on the main body to reposition the main body, thereby further improving the comfort of the user.

[0047] In other embodiments, when the sitting posture detection module 9 is a camera device, it can also have a user identification function to identify different users and transmit the user identification information to the control module 10. The control module 10 sends adjustment information to the damping element according to the stored user usage habits to directly adjust it to the corresponding user's preferred settings.

[0048] The seat reclining damping adjustment method according to the second embodiment of the present invention is applied to the seat 100 according to the first embodiment of the present invention, and the adjustment method includes:

[0049] Step S1, obtaining the weight information of the target user;

[0050] Step S2: obtaining the sitting posture information of the target user, and determining whether the sitting posture of the target user is correct;

[0051] Step S3: If the sitting posture is correct, execute step S4; if the sitting posture is wrong, remind the target user and execute step S2 again;

[0052] Step S4, matching body weight and damping value;

[0053] Step S5, obtaining acceleration information of the target user during the leaning back process;

[0054] Step S6, adjusting and matching acceleration information and damping value;

[0055] Step S7, complete the adjustment.

[0056] It is understandable that if Figure 2As shown, when the user sits down, the weight detection module 8 has feedback, turns on the camera device, obtains the user's sitting posture information and determines whether the user's sitting posture is correct. If the sitting posture is wrong, the user is reminded to adjust the correct sitting posture. If the sitting posture is correct, the weight detection module 8 identifies the user's weight and sends the weight information to the control module 10. The control module 10 matches the weight with the damping value and adjusts the damping value. During the user's leaning back, the acceleration information is obtained and the damping value is matched again and the damping value is fine-tuned to achieve a damping value that adapts to the user.

[0057] According to the adjustment method of the embodiment of the present invention, intelligent reclining damping adjustment can be achieved by comprehensively considering the user's weight, sitting posture and acceleration information during the reclining process, which not only improves the user's comfort, but also reduces health problems caused by improper sitting posture. The operation is simple and easy to adjust, and the accuracy of weight estimation is improved through dual detection of vision and weight.
