Description

Technical Field

[0001] The present invention relates to the technical field of massage chairs, and more particularly to a massage chair with a posture adaptation function. Background Art

[0002] In recent years, with the popularization of the concept of healthy living and the rapid development of the smart home market, the requirements for the comfort and intelligence of massage chairs have become increasingly prominent.

[0003] Currently, most massage chairs on the market adopt mechanical or pneumatic massage mechanisms, specifically including massage driving devices for various body parts, and their corresponding external leather soothing layers. In addition, there is a control center for driving the operation of the massage chair. The control center adjusts the massage method and position according to the user's control, achieving the adaptation of the massage effect and increasing the comfort. However, the above massage chairs still have the following problems, specifically as follows:

[0004] I. Insufficient integration of parameters after multiple manual adjustments by users:

[0005] After a user makes multiple manual adjustments (such as vibration frequency, temperature, position) to an existing massage chair, it usually only covers the latest settings or simply superimposes them, lacking the dynamic fusion of the data of the two adjustments (such as intersection retention and difference set optimization), resulting in the final parameters may deviate from the user's true preferences, affecting the comfort and personalized adaptability.

[0006] II. The initial posture adaptation depends on a fixed theoretical model:

[0007] The initial adjustment of traditional massage chairs is based on a fixed theoretical comfort model, without combining the three-dimensional data of the user's actual body shape (such as the differences in hands, back, and legs), resulting in insufficient posture adaptability after the initial adjustment, and frequent manual correction is required, reducing the user experience efficiency.

[0008] Therefore, the present invention urgently needs to provide an intelligent massage chair with an arm opening and kneading function to solve the above problems. Summary of the Invention

[0009] In order to overcome the above-mentioned defects of the prior art, the present invention provides a massage chair with a posture adaptation function to solve the problems existing in the above background art.

[0010] The present invention provides the following technical solution: a massage chair with an attitude adaptation function, comprising a bottom support frame, a base, a connecting frame, a hand massage component, a lower body massage component, a back massage component, a control panel and a control center. The bottom support frame, the base, the connecting frame, the hand massage component, the lower body massage component, the back massage component and the control panel are all numerically controlled and connected to the control center. A first rotating end for adjusting the angle of the back massage component is provided at the connection between the back massage component and the bottom support frame. A second rotating end for horizontally adjusting the angle of the hand massage component is provided at the connection between the hand massage component and the connecting frame.

[0011] The hand massage component includes a hand data collection terminal and a first massage vibration end. The number of the first massage vibration ends is several and they are evenly distributed inside the hand massage component. The lower body massage component includes a lower body data collection terminal and a second massage vibration end. The back massage component includes a back data collection terminal and a third massage vibration end.

[0012] The control center is controlled and connected with a primary data acquisition module, a primary data analysis module, a secondary data acquisition module, a secondary data analysis module, a final data acquisition module and a final data analysis module.

[0013] The final data acquisition module uses the two adjustment data sets of the secondary data analysis module as the analysis text, and the two adjustment data sets are respectively denoted as a primary start instruction text and a secondary start instruction text. The final data acquisition module processes the analysis text to obtain a final adjustment text and outputs it to the control center. The final adjustment text is based on the secondary calculation of the intersection and difference set of the primary start instruction text and the secondary start instruction text.

[0014] The secondary calculation process is as follows:

[0015] B1. First, denote the primary start instruction text as M1, , and the secondary start instruction text as M2, , and the intersection and difference set matrix is specifically C = M1 * M2;

[0016] B2. Then, based on B1, generate a Boolean intersection matrix: I = diag(sign(C));

[0017] B3. Based on B2, generate a difference set matrix: D = (M2 - M1) * (1 - I);

[0018] B4. Based on B3, construct a weight matrix. Let the intersection weight be r and the difference set weight be (1 - r). The diagonal weight matrix is:

[0019] ;

[0020] ;

[0021] B5. Based on B4 and B1, the final adjusted text vector is: , where ;

[0022] In summary , where and are both user compensation coefficients. Specifically is between 0.1 - 0.3, is between 0.3 - 0.7.

[0023] Technical effects and advantages of the present invention:

[0024] 1. Through the combination of the Boolean intersection matrix and the difference set matrix of the final adjustment module with weight allocation in the present invention, the intersection parameters of the two manual adjustments by the user are combined, so that the consistency preferences are directly retained, and the difference set parameters, that is, the differential requirements are weighted and fused, and finally the final adjusted text that balances the user preferences is produced, significantly improving the personalized adaptability of the massage parameters.

[0025] 2. In the present invention, the three-dimensional features (x i , y i , z i ) of the user's hand, back, and leg are obtained by the primary data acquisition module, compared with the customizable theoretical comfort three-dimensional information, and the difference set vector (x 调1 , y 调1 , z 调1 ) is generated. Through the dynamic angle adjustment of the first rotating end and the second rotating end (such as precise control by a numerical control motor), the initial posture adaptation based on the user's actual body shape is realized, reducing the subsequent manual adjustment frequency and improving the use efficiency.

A second rotating end for horizontally adjusting the angle of the hand massage component 4 is provided at the connection between the hand massage component 4 and the connecting frame 3;

[0033] It should be added in this embodiment that the installation methods of the bottom support frame 1, the base 2, the connecting frame 3, the hand massage component 4, the lower body massage component 5 and the back massage component 6 are all adjustable. The specific connection state is in the form of a conventional massage chair. This embodiment does not limit the specific method, and they are all conventional technical means. The adjustment angles of the first rotating end and the second rotating end are adapted to the adjustment of traditional human body postures. The adjustment angle of the first rotating end is greater than 10% of the conventional setting, and the adjustment angle of the second rotating end is less than 10% of the conventional setting. The adjustment of the first rotating end and the second rotating end is specifically controlled by a numerical control motor matching the control center, mainly to achieve preliminary adaptation adjustment for the user, and can also perform conventional angle adjustment corresponding to the subsequent massage method, increasing the integrity and adaptability of the adjustment process of the present invention;

[0034] The hand massage component 4 includes a hand data collection terminal and a first massage vibration end. The number of the first massage vibration ends is several and they are evenly distributed inside the hand massage component 4. The lower body massage component 5 includes a lower body data collection terminal and a second massage vibration end. The number of the second massage vibration ends is several and they are evenly distributed on the inner surface of the lower body massage component 5. The back massage component 6 includes a back data collection terminal and a third massage vibration end. The number of the third massage vibration ends is several and they are evenly distributed inside the back massage component 6;

[0035] It should be further noted that the first massage vibration end, the lower body data collection terminal, and the third massage vibration end are vibrators of the same series. They are controlled by the control center to present single-point rotational up-and-down reciprocating vibration. Specifically, they can be set as roller components and airbag components and are provided with temperature adjustment ends. The first massage vibration end, the lower body data collection terminal, and the third massage vibration end are all the output ends of the final information of the present invention. Therefore, no specific limitation is made in this embodiment;

[0036] A massage chair with an attitude adaptation function further includes a primary data acquisition module, a primary data analysis module, a secondary data acquisition module, a secondary data analysis module, a final data acquisition module, and a final data analysis module. The information output and input of the primary data acquisition module, the primary data analysis module, the secondary data acquisition module, the secondary data analysis module, the final data acquisition module, and the final data analysis module are all controlled by the control center;

[0037] In the acquisition process of the primary data acquisition module, when the user first lies in this massage device, the hand data collection terminal is used to collect the first text of the user's hand characteristics, the back data collection terminal collects the first text of the back characteristics, and the leg massage end collects the first text of the leg characteristics. The control center makes a primary adjustment instruction based on the first text of the hand characteristics, the first text of the back characteristics, and the first text of the leg characteristics;

[0038] It should be further noted that the first text of the hand characteristics, the first text of the back characteristics, and the first text of the leg characteristics are three-dimensional data information, denoted as (x i , y i , z i );

[0039] The primary data analysis module is used to analyze the first text of the hand characteristics, the first text of the back characteristics, and the first text of the leg characteristics to obtain a primary adjustment text, and output the primary adjustment text value to the control center. The control center issues a primary adjustment instruction to the first rotation end and the second rotation end according to the primary adjustment text output value;

[0040] The processing logic of the primary adjustment text is to compare the three-dimensional data information of the first text of the hand characteristics, the first text of the back characteristics, and the first text of the leg characteristics with the theoretical comfort three-dimensional information. The difference set that appears is the primary adjustment text, denoted as (x 调1 , y 调1 , z 调1 );

[0041] In this embodiment, it should be specifically noted that the theoretical comfort three-dimensional information is the theoretical best lying posture set according to the personal body type and sitting posture. In addition, the theoretical comfort three-dimensional information can be manually set and adjusted, mainly to increase the user's comfort. Therefore, no specific limitation is made;

[0042] In addition, after the output of a single adjustment instruction is completed, the first massage vibration end, the lower body data collection terminal, and the third massage vibration end in all positions are activated;

[0043] The secondary data acquisition module is used to acquire the start-up information of the first massage vibration end, the second massage vibration end, and the third massage vibration end manually adjusted by the user. The secondary data analysis module is used to convert the start-up information manually adjusted by the user into an electrical signal and transmit it to the control center. The control center outputs an electrical signal to perform a single adjustment on the first massage vibration end, the lower body data collection terminal, and the third massage vibration end;

[0044] Among them, the data of the user's manual adjustment includes the start-up item adjustment value, the vibration frequency adjustment value, and the temperature adjustment value. The above-mentioned manual adjustment data is denoted as m i ;

[0045] After the secondary data analysis module is activated twice, the final data acquisition module is activated.

[0046] In this embodiment, taking the activation of the secondary data analysis module twice as an example:

[0047] The final data acquisition module uses the two adjustment data sets of the secondary data analysis module as the analysis text, and the two adjustment data sets are respectively denoted as the first start instruction text and the second start instruction text.

[0048] The final data acquisition module processes the analysis text to obtain the final adjustment text and outputs it to the control center. The final adjustment text is based on the secondary calculation of the intersection and difference set of the first start instruction text and the second start instruction text.

[0049] The secondary calculation process is as follows:

[0050] B1. First, denote the first start instruction text as M1, , and denote the second start instruction text as M2, , and the intersection and difference set matrix is specifically C = M1 * M2;

[0051] B2. Then, based on B1, generate the Boolean intersection matrix: I = diag(sign(C));

[0052] B3. Based on B2, generate the difference set matrix: D = (M1 - M1) * (1 - I);

[0053] B4. Based on B3, construct the weight matrix. Let the intersection weight be r and the difference set weight be (1 - r). The diagonal weight matrix is:

[0054] ;

[0055] ;

[0056] B5. Based on B4 and B1, the final adjusted text vector is:

[0057] , where ;

[0058] In summary , where and are both user compensation coefficients. Specifically is between 0.1 - 0.3, is between 0.3 - 0.7.

[0059] This embodiment is based on automatic intelligent matching adjustment under the condition of two manual adjustments, which increases the adaptability during the massage process of the massage chair. And the final adjustment belongs to real-time adjustment, making the matching degree higher during the entire intelligent massage process.

[0060] The working principle of this embodiment:

[0061] Preparation stage: The user lies on the massage chair. Then, the hand data collection terminal is used to collect the first text of the user's hand features, the leg massage terminal collects the first feature text of the legs, and the back data collection terminal collects the first text of the back features. Through the first text of the hand features, the first feature text of the legs, and the first text of the back features, the control center adjusts the size of the massage chair for the user. Specifically, it adjusts the clearance space between the lower body massage component 5 and the lower body data collection terminal, the angle and length of the back massage component 6, and the clearance length, so that the massage chair matches the user. Then, the control center outputs a preliminary start instruction to start the first massage vibration terminal, the foot massage terminal, and the third massage vibration terminal to achieve a first massage;

[0062] First adjustment stage:

[0063] During the first massage process, if the user does not make adjustments, the first massage vibration terminal, the foot massage terminal, and the third massage vibration terminal complete the massage according to the first massage start frequency within a predetermined time;

[0064] If the user makes adjustments, at this time, the control center collects the first adjustment instruction and outputs the first start instruction text. The first massage vibration terminal, the foot massage terminal, and the third massage vibration terminal make a first adjustment to achieve a second massage;

[0065] Second adjustment process:

[0066] During the second massage process, if the user does not make adjustments, the first massage vibration terminal, the foot massage terminal, and the third massage vibration terminal complete the massage according to the second massage start frequency within a predetermined time;

[0067] If the user makes an adjustment, the control center collects the secondary adjustment instruction at this time, outputs the secondary start instruction text, and the first massage vibration end, the foot massage end, and the third massage vibration end perform secondary adjustment to achieve three times of massage;

[0068] The process of three - time adjustment:

[0069] During the secondary massage process, if the user does not make an adjustment, the first massage vibration end, the foot massage end, and the third massage vibration end complete the massage at the secondary massage start frequency within a predetermined time;

[0070] If adjustment is needed, manual adjustment and automatic adjustment can be selected at this time;

[0071] During the automatic adjustment massage process, compare the information text of the first - time adjustment with the preliminary start instruction text, calculate the first - time output difference set for the adjustment of the first massage vibration end, the foot massage end, and the third massage vibration end. Compare the information text of the secondary adjustment with the first - time start instruction text, calculate the second - time output difference set for the adjustment of the first massage vibration end, the foot massage end, and the third massage vibration end. Compare the first - time output difference set with the second - time output difference set to obtain the text difference set. Generate the third - time start text according to the text difference set, and the first massage vibration end, the foot massage end, and the third massage vibration end perform three - time adjustment to achieve four - time massage;

[0072] The process of four - time adjustment;

[0073] The process of four - time adjustment is the same as that of three - time adjustment until the massage adjustment process is completed.

[0074] It should be further noted that during the massage process, if the user does not make an adjustment, the massage is completed according to the current massage start frequency, and if the user makes an adjustment, it enters the next adjustment stage;

[0075] Embodiment 2 - 5

[0076] The difference between the corresponding embodiment and Embodiment 1 is that the secondary data analysis module is started n + 2 times, and the secondary calculation process is the calculation of the intersection and difference set of n + 2 times of text data. Based on the fact that Embodiments 1 - 5 and the traditional massage chair are adapted for 50 person - times of use, the following table is made for result comparison:

[0077]

[0078] In the table, H is the average number of times for a single person - time of manual adjustment received by the massage chair after the final data acquisition module is started. It can be seen that the more the original data is collected by the secondary data analysis module, the higher the automatic adaptation effect. However, when the number of times of data collection by the secondary data analysis module exceeds four times, it is equivalent to the adjustment times of the existing technology.

[0079] Second: In the accompanying drawings of the disclosed embodiments of the present invention, only the structures related to the disclosed embodiments are involved. For other structures, reference may be made to the general design. Without conflict, the same embodiment and different embodiments of the present invention can be combined with each other;

[0080] Finally: The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
