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: I. Insufficient integration of parameters after multiple manual adjustments by users: After the user makes multiple manual adjustments (such as vibration frequency, temperature, position) to the 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 retaining the intersection and optimizing the difference set), resulting in the final parameters may deviate from the user's true preferences, affecting the comfort and personalized adaptability.

[0004] II. Initial posture adaptation depends on a fixed theoretical model: 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 the need for frequent manual correction, reducing the user experience efficiency.

[0005] 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

[0006] 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.

[0007] The present invention provides the following technical solutions: A massage chair with a posture adaptation function includes 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, and 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; 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 leg massage end, a foot massage end, and a lower body data collection terminal. The number of the lower body data collection terminals is several, and they are evenly distributed on the inner surface of the lower body massage component. The back massage component 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; The control center is connected to 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 in a controlled manner.

[0008] Further, the first massage vibration end, the lower body data collection terminal, and the third massage vibration end are of the same series of vibrators, and are controlled by the control center to present a single-point rotating up-and-down reciprocating vibration. Specifically, they can be set as a roller assembly, an airbag assembly, and are provided with a temperature adjustment end; Further, 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 features, the back data collection terminal collects the first text of the back features, and the lower body data collection terminal collects the first text of the leg features. The control center makes a primary adjustment instruction according to the first text of the hand features, the first text of the back features, and the first text of the leg features; Further, the first text of the hand features, the first text of the back features, and the first text of the leg features are three-dimensional data information, denoted as (x i , y i , z i ). The specific logic for establishing the three-dimensional data information is as follows: taking the front of the base as the X axis, the end face of the base away from the lower body massage component as the Y axis, the bottom surface of the base as the Z axis, and corresponding to the specific data values of (x, y, z) in centimeters.

[0009] Further, the hand data collection terminal collects data by means of an internally integrated sensor. Various sensors are evenly distributed inside the hand massage component. These sensors may include pressure sensors and capacitance sensors. When the user's hand touches the massage component, the sensors can sense information such as the pressure distribution and contour shape of the hand, and convert these physical signals into electrical signals. Based on a preset algorithm, the electrical signals are further processed into three-dimensional data information, in the form of (x i , y i , z iRecord the first text of hand features in the form of (), where the establishment logic of the three-dimensional data information is based on the front of the base as the X-axis, the end face of the base away from the lower body massage component as the Y-axis, the bottom surface of the base as the Z-axis, and the specific data values are corresponding in centimeters.

[0010] The lower body data collection terminal collects data through contact pressure sensing and position detection technologies. On the inner surface of the lower body massage component, pressure sensing elements are evenly distributed. When the user's leg contacts the lower body massage component, the pressure sensing elements will generate corresponding electrical signal changes according to the pressure magnitudes of different parts of the leg, so as to obtain the pressure distribution data of the leg. At the same time, combined with the position detection sensor, the relative position information of each part of the leg in the massage component can be determined. These information are processed and converted into the first text of leg features in the form of three-dimensional data (x i ,y i ,z i ), and the setting of the coordinate axes is consistent with that of the hand data collection, which is used to accurately reflect the features of the leg.

[0011] The back data collection terminal collects data by combining infrared scanning and pressure sensing. Inside the back massage component, the infrared emitter and receiver work together. By emitting infrared signals and receiving the reflected signals, the contour information of the back can be obtained. At the same time, the pressure sensors evenly distributed in the back massage component will real-time sense the pressure magnitudes of different parts of the back on the massage component, integrate the contour data obtained by infrared scanning and the pressure data collected by the pressure sensors, and convert them into three-dimensional data information according to the established algorithm to form the first text of back features (x i ,y i ,z i ), which provides comprehensive and accurate back feature data for the subsequent adjustment of the massage chair.

[0012] Further, the primary data analysis module is used to analyze the first text of hand features, the first text of back features, and the first text of leg features to obtain the primary adjustment text, and output the primary adjustment text value to the control center. The control center outputs the primary adjustment instruction to the first rotating end and the second rotating end according to the primary adjustment text value.

[0013] Further, the secondary data collection module is used to collect the start information of the first massage vibration end, the lower body data collection terminal, and the third massage vibration end manually adjusted by the user. The secondary data analysis module is used to convert the start 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 make a primary adjustment to the first massage vibration end, the lower body data collection terminal, and the third massage vibration end; Further, the user manual adjustment data includes a startup item adjustment value, a vibration frequency adjustment value, and a temperature adjustment value, and the above manual adjustment data is denoted as m i ; Further, 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 startup instruction text and a secondary startup 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 startup instruction text and the secondary startup instruction text.

[0014] Technical effects and advantages of the present invention: 1. Through the combination of the Boolean intersection matrix and the difference set matrix of the final adjustment module in the present invention and the weight distribution, the intersection parameters of the two manual adjustments by the user are such that the consistency preferences are directly retained, and the difference set parameters, that is, the differential requirements, are weighted and fused. Finally, a final adjustment text that balances the user preferences is generated, significantly improving the personalized adaptability of the massage parameters.

[0015] 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 a 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.

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 the traditional human body posture. The adjustment angle of the first rotating end is more 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 to match the control center, mainly to achieve a preliminary adaptation adjustment for the user, and can also perform a conventional angle adjustment corresponding to the subsequent massage method, increasing the integrity and adaptability of the adjustment process of the present invention; The hand massage component 4 includes a hand data collection terminal and a first massage vibration end.

Specifically, they can be set as roller assemblies and airbag assemblies and are provided with a temperature adjustment end. The first massage vibration end, the lower body data collection terminal, and the third massage vibration end are all output terminals of the final information of the present invention. Therefore, no specific limitation is made in this embodiment; 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; The acquisition process of the primary data acquisition module is that 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; 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 ). The establishment logic of the three-dimensional data information is specifically as follows: taking the front of the base 2 as the X axis, the end face of the base 2 away from the lower body massage component 5 as the Y axis, the bottom surface of the base 2 as the Z axis, and corresponding to the specific data values of (x, y, z) in centimeters; 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 rotating end and the second rotating end according to the primary adjustment text output value; 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 ); 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 sitting posture corresponding to the individual body type. In addition, the theoretical comfort three-dimensional information can be manually set and adjusted, mainly to increase the comfort of the user. Therefore, no specific limitation is made; 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 started; The secondary data acquisition module is used to collect the start information of the first massage vibration end, the lower body data collection terminal, and the third massage vibration end manually adjusted by the user. The secondary data analysis module is used to convert the start 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; Among them, the user manual adjustment data includes the start item adjustment value, the vibration frequency adjustment value, and the temperature adjustment value. The above manual adjustment data is denoted as m i ; After the secondary data analysis module is started twice, the final data acquisition module is started. In this embodiment, the example of the secondary data analysis module being started twice is taken: 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. 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. The secondary calculation process is as follows: B1. First, denote the first start instruction text as M 1 , , and denote the second start instruction text as M 2 , , and the intersection and difference set matrix is specifically C = M 1 *M 2 ; B2. Then, based on B1, generate the Boolean intersection matrix: I = diag(sign(C)); B3. Based on B2, generate the difference set matrix: D = (M 1 - M 1 ) * (1 - I); 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:

[0023]

[0024] B5. Based on B4 and B1, the final adjustment text vector is: , where

[0025] In summary , where and are both user compensation coefficients, specifically is between 0.1 - 0.3, is between 0.3 - 0.7.

[0026] This embodiment is based on the automated intelligent matching adjustment under the condition of two manual adjustments, which increases the adaptability during the massage process of the massage chair. Moreover, the final adjustment belongs to real-time adjustment, and the matching degree of the entire intelligent massage process is higher.

[0027] The working principle of this embodiment: 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 text of the leg features, and the back data collection terminal collects the first text of the back features. Through the first text of the hand features, the first text of the leg features, 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 gap 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 gap 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 one-time massage; First adjustment stage: 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; 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 perform the first adjustment to achieve the second massage; Second adjustment process: 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; If the user makes adjustments, at this time, the control center collects the second adjustment instruction and outputs the second start instruction text. The first massage vibration terminal, the foot massage terminal, and the third massage vibration terminal perform the second adjustment to achieve the third massage; Third adjustment process: 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; If adjustment is required, at this time, manual adjustment and automatic adjustment can be selected; Automatically adjust the massage process. Compare the information text of one adjustment with the preliminary start instruction text, calculate the first output difference set of the adjustments of the first massage vibration end, the foot massage end, and the third massage vibration end. Compare the information text of the second adjustment with the first start instruction text, calculate the second output difference set of the adjustments of the first massage vibration end, the foot massage end, and the third massage vibration end. Compare the first output difference set with the second output difference set to obtain the text difference set. Generate the third start text based on the text difference set, and perform three adjustments on the first massage vibration end, the foot massage end, and the third massage vibration end to achieve four massages; Four adjustment processes; The four adjustment processes are the same as the three adjustment processes until the massage adjustment process is completed.

[0028] It should be further noted that during the massage process, if the user does not make adjustments, the massage will be completed according to the current massage start frequency. If the user makes adjustments, it will enter the next adjustment stage; Embodiments 2 - 5 The difference between the corresponding embodiments 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 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:

[0029] In the table, H is the average number of times the massage chair receives manual adjustments for a single person - time after the final data acquisition module is started. It can be seen that the more original data is collected by the secondary data analysis module, the higher the automated adaptation effect. However, when the number of times of data collection by the secondary data analysis module exceeds four, it is equivalent to the adjustment times of the existing technology.

[0030] Secondly, in the attached drawings of the disclosed embodiments of the present invention, only the structures related to the disclosed embodiments are involved. Other structures can refer to the general design. Without conflict, the same embodiment and different embodiments of the present invention can be combined with each other; Finally, the above - mentioned are only the preferred embodiments of the present invention and are not used to limit the present invention.
