[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0030] Figure 1As shown in the method steps of a spine protection table and chair joint debugging method provided in an embodiment of the present application. The present application provides a spine protection table and chair joint debugging method, which is applied to a table and chair set including a table and a chair that can move relative to each other.

[0031] In an embodiment, as shown in the method steps of a spine protection table and chair joint debugging method provided in an embodiment of the present application. The present application provides a spine protection table and chair joint debugging method, which is applied to a table and chair set including a table and a chair that can move relative to each other. Figure 1

[0032] Step 110, obtaining the body data of the user and the application data of the current application scenario.

[0033] In this step, a sensor can be arranged at the entrance of the current application scenario where the table and chair set is located to detect the body data of the user, including the height, weight, etc. of the user. The application data of the current application scenario includes the application type currently being carried out in the current application scenario, such as the table and chair set being located in a school classroom or a family study, and the application type corresponding to the application data includes various sitting postures and various application scenarios that need to pay attention to eye health, such as morning reading, reading books, writing, listening to class, recess, short rest, and nap. The application data can be determined by the upper server according to the current time period, can be set by the user himself / herself, or can be set by the supervisor of the current application scenario.

[0034] Step 120, calling the standard posture data corresponding to the body data under the current application data.

[0035] In this step, the standard posture data corresponding to the body data can be called from the network through online data, for example, in the writing scenario in a school classroom, the standard table height and chair height corresponding to the height can be called according to the provisions of "Functional Dimensions and Technical Requirements for Student Desk and Chair" GB / T3976-2014; for another example, the reference posture data can be taken as the standard posture data from the perspective of youth health by ergonomics experts. Specifically, for example, in the application type of writing, the standard posture data given by the expert for a height of 160 is that the table top is 70 cm high, the chair surface is 40 cm high, the edges of the table and chair facing each other are 5 cm apart, and the chair back angle is 95°; for another example, in the application type where the eyes need to look straight ahead, based on the consideration of relieving the spine, the standard posture data given by the expert for a height of 160 is that the table top is 70 cm high, the chair surface is 35 cm high, the edges of the table and chair facing each other are 5 cm apart, and the chair back angle is 130°; for example, in the writing operation application type, the standard posture data given by the expert for a height of 160 is that the table top is 70 cm high, the chair surface is 40 cm high, the edges of the table and chair facing each other are 15 cm apart, and the chair back angle is 125°.

[0036] Step 130, calling the reference posture data corresponding to the application in the historical data of the user.

[0037] ​In this step, the reference posture data is the posture data that the user adjusts by himself based on the standard posture data in the last same application type, and this data is taken as the reference. The user's self-habit can be fully considered, and the user's sitting posture is not determined by the standard posture suggested by the expert.

[0038] Step 140, adjusting the desk and chair set to the target posture according to the standard posture data and the standard weight, the reference posture data and the reference weight.

[0039] In this step, since the body structure of each person is different, individual differences will occur. The user may not completely and perfectly adapt to the ergonomic standard posture suggested by the expert. Therefore, the present application considers the expert suggestion given according to ergonomics and the user's self-habit, and assigns respective weights to the standard posture and the reference posture. Thus, the user can be corrected in body posture while the individual differences of the user are fully considered to make the user more comfortable.

[0040] Step 150, if the user adjusts the posture of the desk and chair set again, updating the reference posture data according to the posture data that is kept for the longest time.

[0041] In this step, the reference posture data is updated. If the user adjusts the posture again, it means that the user does not completely adapt to the standard posture corresponding to the standard posture data. The posture data that is kept for the longest time after the second adjustment is the most satisfactory posture of the user. This posture data that is kept for the longest time is taken as the reference posture data for use in the same application type next time.

[0042] Step 160, if the user does not adjust the posture of the desk and chair set again, obtaining the reference posture data according to the target posture.

[0043] In this step, if the user does not adjust the posture, it means that the user adapts to the standard posture data. The reference posture data is not needed, and the standard posture data can be taken as the reference posture data.

[0044] In application, the spine protection table and chair joint adjustment method driven by multi-dimensional data realizes accurate and scientific adjustment. In the running process, the system first collects the body data such as height and weight of the user entering the application scene through the sensor, and obtains the specific application type in the current application scene. Based on these data, the system calls the standard posture data formulated from the health protection of the spine, and provides scientific posture guidance for the user. For example, when writing for a long time, adjust the height of the table, the height of the chair and the angle of the chair back, so that the spine tends to be upright, and the user can maintain an upright posture when writing to shape a good body posture. For example, in the application scene of reading books or morning reading, adjust the distance between the table and the chair and the inclination of the chair back based on the consideration of relieving the spine, and reduce the adverse effects of long sitting on the spine. At the same time, the method also calls the reference posture data in the user's historical use, combines the standard posture of scientific spine protection with the user's own habits, adjusts the table and chair set to the target posture by reasonably allocating the weight, corrects the bad body posture, prevents the spine problem, and also considers the individual difference to improve the comfort, protects the spine while limiting the comfortable eye distance. In addition, the method has the ability of dynamic learning and optimization. If the user performs secondary adjustment, the system automatically records the posture data with the longest duration and updates the reference posture, so that the subsequent adjustment is more in line with the individual spine protection needs; if the user does not perform secondary adjustment, the standard posture is set as the reference posture by default. Through this mechanism, the system continuously optimizes the adjustment strategy, reduces the user's repeated operation, and meets the spine protection needs of different people and multiple scenes with universal design, improves the human-computer interaction experience and system practicability, and improves the protection effect of the user's spine health.

[0045] Figure 2 The method steps for obtaining application data are shown. In an embodiment, as shown in Figure 2 Step 110 includes:

[0046] Step 111, obtain the height data and weight data collected when the user enters the scene, or obtain the height data and weight data input by the user.

[0047] Step 112, obtain the current application demand of the place where the table and chair set are located.

[0048] Step 113, if the user confirms the current application demand, generate application data.

[0049] Step 114, if the user calls other application demand, generate application data according to other application demand.

[0050] In this embodiment, the application data is confirmed twice. When the user enters the current application scene, the upper server determines the application data according to the current time period, or the supervisor of the current application scene can set the application data. After the automatic setting of the current application requirement, the user confirms the application requirement twice. If the confirmation is correct, the application data is automatically set. When the user wants to use other application types in the current scene, for example, the current application scene is automatically set to the writing mode, and the user wants to write in the reading mode, the user calls the application data corresponding to the reading application requirement, and generates the application data called by the user.

[0090] Figure 10 As shown, if the user adjusts the posture of the table and chair set twice, the spine protection table and chair joint adjustment method further includes: Figure 10

[0091] Step 170, monitoring the frequency of change of the user's sitting posture in a preset time period.​

[0092] Step 180, obtaining a first weight correction parameter according to the frequency of the change in the sitting posture.

[0093] In this step, the first weight correction parameter is inversely proportional to the frequency of the change in the sitting posture. The greater the frequency of the change in the sitting posture, the more uncomfortable the posture after the secondary adjustment, and thus the reference weight needs to be reduced. The smaller the frequency of the change in the sitting posture, the more comfortable the posture after the secondary adjustment, and thus the reference weight needs to be increased. Specifically, the first weight correction parameter can be set to be between 0.1 and 2. Specifically, for example, when the frequency of the change in the sitting posture is 10 times within 1 minute, the first weight correction parameter is 1; when the frequency of the change in the sitting posture is 20 times within 1 minute, the first weight correction parameter is 0.1; and when the frequency of the change in the sitting posture is 0 times within 1 minute, the first weight correction parameter is 2. The first weight correction parameters corresponding to other frequencies of the change in the sitting posture can be calculated according to the above three sampling values. Specifically, a vibration sensor is arranged in the chair, and a shake is counted when the vibration amplitude is greater than a certain preset value.

[0094] Step 190, correcting the reference weight according to the first weight correction parameter for next use.

[0095] In this embodiment, after the reference weight is corrected to obtain the corrected reference weight, the standard weight is adaptively adjusted to be lower, so that the sum of the standard weight and the reference weight is 100%. For example, the initial value of the reference weight is 30%, the first weight correction parameter is calculated to be 1.2, and thus the reference weight under the same application type next time is 1.2*30% = 36%, and the standard weight is adaptively adjusted to be 64%.

[0096] Figure 11 As shown in FIG. 6, the method for correcting the reference weight according to the evaluation score includes the following steps. Figure 11 As shown in FIG. 6, if the user adjusts the posture of the desk and chair set again, the spine protection desk and chair joint adjustment method further includes the following steps.

[0097] Step 200, when the current application data corresponds to the end of the application scene, if the evaluation score of the user is obtained, the first weight correction parameter is eliminated.

[0098] Step 210, obtaining a second weight correction parameter according to the evaluation score.

[0099] In this step, the second weight correction parameter is proportional to the evaluation score. The higher the evaluation score, the more comfortable the posture after the secondary adjustment, and the reference weight needs to be increased. The lower the evaluation score, the less comfortable the posture after the secondary adjustment, and the reference weight needs to be reduced. The value range of the second weight correction parameter is 0.1-2. Specifically, for example, when the evaluation score is 10 points, the second weight correction parameter is 2; when the evaluation score is 5 points, the second weight correction parameter is 1; and when the evaluation score is 0 points, the second weight correction parameter is 0.1; and the second weight correction parameter corresponding to other evaluation scores is calculated according to the above three sampling values.

[0100] Step 220, correcting the reference weight according to the second weight correction parameter for next use.

[0101] In this embodiment, the reference weight is corrected. If the user performs the comfort evaluation, the first weight correction parameter is ignored, the modified reference weight is obtained according to the second weight correction parameter, and the standard weight is adaptively adjusted to be lower, so that the sum of the standard weight and the reference weight is 100%. For example, the initial value of the reference weight is 30%, the second weight correction parameter is calculated to be 1.3, and the reference weight of the next same application type is 1.3*30%=39%, and the standard weight is adaptively adjusted to be 61%.

[0102] Figure 12 As shown in the method steps of adjusting the table and chair according to the correction instruction. In an embodiment, as shown in the method steps of adjusting the table and chair according to the correction instruction. In an embodiment, as shown in Figure 12 After step 120, the spine protection table and chair joint debugging method further includes:

[0103] Step 230, if the body correction instruction for the user is obtained, the table and chair set is adjusted to the target posture according to the standard posture data.

[0104] In this embodiment, when it is necessary to forcibly correct the user's posture, the reference posture data defined by the user is not considered, that is, steps 130 and 140 are not executed, and in the application state, only the standard posture data is used to adjust the posture of the table and chair set.

[0105] Figure 13 As shown in the execution step diagram after the secondary adjustment in the body correction. In an embodiment, as shown in the execution step diagram after the secondary adjustment in the body correction. In an embodiment, as shown in Figure 13 After step 230, the spine protection table and chair joint debugging method further includes:

[0106] Step 240, if the user adjusts the posture of the table and chair set, the table and chair set is adjusted to the target posture after the secondary adjustment posture is maintained for a preset secondary posture duration.

[0107] In this embodiment, since the user's posture is forcibly corrected, even if the user adjusts the posture of the table and chair set again, it will return to the target posture corresponding to the standard posture data after a period of time. The secondary posture preset time can be set to a value in 1-10 minutes, and the secondary posture preset time provides a certain relaxation time for the user, and the user can ride for a certain time according to his own preference. This embodiment can achieve the effect of forcibly correcting the user's posture according to ergonomics.

[0108] Figure 14 The system module diagram of the spine protection table and chair joint debugging system is shown. The present application also provides a spine protection table and chair joint debugging system, which is applied to a table and chair set, and the table and chair set includes a table and a chair that can move relative to each other, such as Figure 14 As shown, the spine protection table and chair joint debugging system includes a data acquisition module 101, a posture acquisition module 102, a posture adjustment module 103, and a posture feedback module 104.

[0109] The data acquisition module 101 is configured to acquire body data of a user and application data of a current application scenario.

[0110] The posture acquisition module 102 is in communication connection with the data acquisition module 101, and the posture acquisition module 102 is configured to call standard posture data corresponding to the body data under the current application data, and call reference posture data corresponding to the application in the historical data of the user.

[0111] The posture adjustment module 103 is in communication connection with the posture acquisition module 102, and the posture adjustment module 103 is configured to adjust the table and chair set to switch to a target posture according to the standard posture data and the standard weight, and the reference posture data and the reference weight.

[0112] The posture feedback module 104 is in communication connection with the posture acquisition module 102, and the posture feedback module 104 is configured to update the reference posture data according to the posture data with the longest time length if the user adjusts the posture of the table and chair set again, and obtain the reference posture data according to the target posture if the user does not adjust the posture of the table and chair set again.

[0113] In application, the spine protection table and chair joint adjustment method is driven by multi-dimensional data as the core, and precise and scientific adjustment is realized. In the running process, the system first collects the body data such as height and weight of the user entering the application scene through the sensor, and obtains the specific application type in the current application scene. Based on these data, the system calls the standard posture data formulated from the health protection of the spine, and provides scientific posture guidance for the user. For example, when writing for a long time, the height of the table, the height of the chair and the angle of the chair back are adjusted, so that the spine tends to be upright, and the user can maintain an upright posture when writing to shape a good body posture; in the video watching scene, the distance between the table and the chair and the inclination of the chair back are adjusted based on the consideration of relieving the spine, and the adverse effects of long sitting on the spine are reduced. At the same time, the method also calls the reference posture data in the user's historical use, combines the standard posture of scientific spine protection with the user's own habits, adjusts the table and chair set to the target posture by reasonably allocating the weight, corrects the bad body posture, prevents the spine problems, and also takes into account the individual differences to improve the comfort, protects the spine while limiting the comfortable eye distance. In addition, the method has the ability of dynamic learning and optimization. If the user makes a second adjustment, the system automatically records the posture data with the longest duration and updates the reference posture, so that the subsequent adjustment is more in line with the individual spine protection needs; if the user does not make a second adjustment, the standard posture is set as the reference posture by default. Through this mechanism, the system continuously optimizes the adjustment strategy, reduces the user's repeated operation, and meets the spine protection needs of different people and multiple scenes with universal design, improves the human-computer interaction experience and system practicability, and improves the protection effect of the user's spine health.

[0114] The application also provides a table and chair set, which comprises a table and a chair that can move relative to each other and the aforementioned spine protection table and chair joint adjustment system. Specifically, the table and chair set can use the existing technology of linkable and adjustable table and chair. In addition, the table can also use the commonly used lifting table on the market, the chair can use the commonly used lifting and movable chair on the market, and the angle of the chair back of the chair can be adjusted. A distance detection mechanism is provided between the table and the chair to detect the distance between the table and the chair, i.e. to detect the aforementioned current relative distance, and the relative distance between the table and the chair is adjusted to the sum of the first relative adjustment value and the second relative adjustment value through the feedback data of the distance detection mechanism. The spine protection table and chair joint adjustment system is electrically connected with the table and the chair to control the position and posture adjustment of the table and the chair; or the spine protection table and chair joint adjustment method is loaded into the processor of the table and the chair to control the position and posture adjustment of the table and the chair.
