[0001] This invention relates to the field of massage chair technology, and specifically discloses a personalized vertical rhythmic massage control method, device, and rhythmic massage chair. Background Technology

[0002] With modern people spending long hours sitting at work and reducing physical activity, problems such as stiff neck and shoulders, lower back strain, and limb fatigue are becoming increasingly common. Traditional manual massage is limited by time, location, and cost, while automated massage equipment is gradually becoming an important medium for health and relaxation at home and in business. Rhythmic massage chairs are also developing rapidly and continuously iterating their technology.

[0003] The Rhythmic Massage Chair relies on the collaborative work of multiple systems, including mechanical transmission, pneumatic control, intelligent sensing, and electronic control algorithms. Its core principle is to simulate traditional manual massage techniques, using mechanical force and air pressure to act on human muscles, meridians, and acupoints to achieve effects such as muscle relaxation, fatigue relief, and improved blood circulation.

[0004] Most existing rhythmic massage chairs use fixed intensity and fixed modes for control, which cannot automatically adjust massage parameters according to the user's physical condition. This can easily lead to problems such as insufficient massage intensity or excessive pressure, affecting the user experience and safety. Summary of the Invention

[0010] Preferably, the set events include sudden changes in the current of the walking motor corresponding to the mechanism, sudden changes in the pulse width of the counting sensor, or activation of the swing arm optocoupler sensor.

[0011] Preferably, it further includes: When the weight is less than the threshold, it is determined that there is no user on the current rhythmic massage chair or the user has left the chair; The rhythmic massage chair is controlled to enter power-saving mode, performing massage operations with minimal intensity.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] Example 1 Please see Figure 1 and Figure 2 The first embodiment of the present invention provides a personalized vertical rhythmic massage control method, which is applied to a rhythmic massage chair and executed by a processor configured within the rhythmic massage chair to achieve the following steps: S101 uses a pressure sensor to detect the pressure acting on the surface of the rhythmic massage chair.

[0020] In this embodiment, the structure of the rhythmic massage chair is as follows: Figure 3 As shown, it generally includes a seat 10, a backrest 20, and armrests 30. Among them, as... Figures 4 to 6 As shown, massage components can be installed within the seat 10 and backrest 20. These massage components generally include massage heads 41, gears 42, and various types of motors, such as a walking motor 43, a telescopic motor 44, a kneading motor 45, and a tapping motor 46. Different motors can control the massage heads 41 to perform various functions such as walking (massage), telescopic movement, kneading, and tapping. In this embodiment, to provide a better massage experience for the user, the working intensity of different motors needs to be set according to the different heights and weights of different users.

[0021] In order to detect the weight of the user sitting on the seat 10, a first pressure sensor 11 can be installed on the seat, and in order to detect whether the user's arm is placed on the armrest 30, a second pressure sensor 31 can also be installed on the armrest 30.

[0022] In this embodiment, as Figure 7 As shown, the first pressure sensor 11 can be installed on the seat surface 10 of the rhythmic massage chair in the following manner: First, a supporting sheet metal 12 is placed at the installation position. Then, a shock-absorbing rubber 13 is placed on the supporting sheet metal 12. Next, the first pressure sensor 11 is attached to the sensor metal beam and fixed to the shock-absorbing rubber 13. Finally, a supporting plate 14 is encapsulated on the outside to protect the pressure sensor 11. It is understood that the second pressure sensor 31 can be installed using a similar structure, which will not be described in detail here.

[0023] In this embodiment, the pressure sensor may include a strain gauge, a Wheatstone bridge circuit, an amplifier circuit, an analog-to-digital converter (A / D) circuit, and a communication chip. When the metal beam experiences pressure, it undergoes slight bending deformation; the strain gauge is stretched / compressed, causing a change in resistance value, which is converted into a weak voltage signal. After amplification and filtering by the amplifier circuit, the analog-to-digital converter converts the analog electrical signal into a digital signal, which is then transmitted to the processor by the communication chip.

[0024] In this embodiment, the first pressure sensor 11 is used to monitor pressure changes on the chair surface 10 in real time and convert the pressure signal into an electrical signal output. Figure 8As shown, when the user is not yet sitting on the rhythmic massage chair, the pressure value detected by the pressure point 111 of the first pressure sensor 11 is zero or close to zero. When the user sits on the rhythmic massage chair, the user's weight is transmitted to the first pressure sensor 11 through the chair surface, and the pressure value detected by the pressure point 111 of the first pressure sensor 11 increases with the increase of the user's weight. The analog signal output by the first pressure sensor 11 is processed by the signal acquisition circuit and then transmitted to the processor.

[0025] S102, obtain the current weight acting on the seat surface based on pressure changes.

[0026] Specifically, in this embodiment, to avoid the impact caused by the user sitting down, the collected pressure values ​​are processed to prevent vibration. Specifically, pressure value sampling is delayed by a first time interval, and multiple pressure values ​​are continuously collected in a second time interval. These pressure values ​​are then averaged arithmetically, and the result is used as the current weight applied to the chair surface 10. Using delayed sampling and averaging effectively filters out measurement errors caused by pressure fluctuations, improving the accuracy of weight detection.

[0027] It should be noted that in this embodiment, the first time can be 0.5 seconds and the second time can be 2 seconds. However, it should be understood that in other embodiments of the present invention, the first time and the second time can be set according to actual needs, and these solutions are all within the protection scope of the present invention.

[0028] S103, when the weight is determined to be greater than the preset threshold, it is determined that there is a user on the current rhythmic massage chair.

[0029] In this embodiment, for example, a preset threshold can be set to 20 kg. When the calculated weight value is greater than 20 kg, it is determined that there is a user on the rhythmic massage chair; when the calculated weight value is less than or equal to 20 kg, it is determined that there is no user on the rhythmic massage chair or that the user has left the chair. When it is determined that the user has left the chair, the processor controls the rhythmic massage chair to enter a power-saving mode, performing the massage operation with the minimum intensity or stopping the massage.

[0030] S104 detects the command to start the massage, performs shoulder position detection, and determines the user's height based on the shoulder position detection results.

[0031] In this embodiment, the command to start the massage can be sent via remote control, control panel, or voice control. Upon receiving the command, the processor first performs shoulder position detection. Specifically, the processor controls the shoulder detection mechanism to move downwards along the guide rail from an initial position (corresponding to a fixed preset height, typically located at the top of the massage chair). During this movement, the mechanism records a walking count. When the mechanism reaches the user's shoulder position, the processor records the current walking count. There are several ways to determine if the mechanism has moved to the user's shoulder position. For a 4D mechanism, shoulder position detection relies on the extension of the massage balls. When the massage balls press against the shoulder, the current of the walking motor changes abruptly, or the pulse width of the counting sensor changes abruptly; at this point, it is determined that the mechanism has moved to the user's shoulder position. For a 3D mechanism, shoulder position detection is determined by the activation of the optical coupler sensor on the shoulder arm.

[0032] In this embodiment, the processor can look up the corresponding height value in a pre-stored shoulder position lookup table based on the recorded walking count value as the user's height. Specifically, the walking distance can be calculated by multiplying the stride length of each step by the walking count value. Then, the user's shoulder height can be obtained by subtracting the walking distance from the preset height. Finally, the user's height can be obtained based on the ratio between shoulder height and body height. The ratio between shoulder height and body height can be established through a large amount of human body measurement data.

[0033] In this embodiment, in particular, to facilitate calculation, a shoulder position reference table can be directly established based on the measured data. The shoulder position reference table records the mapping relationship between different walking count values ​​and corresponding height values, so the height can be obtained directly from the walking count value without further conversion.

[0034] The S105 adaptively adjusts the operating parameters of the rhythmic massage chair based on the user's weight and height.

[0035] In this embodiment, the processor looks up the corresponding operating parameters in a pre-stored mapping table based on the user's weight and height. The mapping table pre-stores the mapping relationships between different weight and height ranges and their corresponding operating parameters. For example, the weight range is divided into four intervals: below 50 kg, 50-70 kg, 70-90 kg, and above 90 kg; the height range is divided into four intervals: below 160 cm, 160-175 cm, 175-190 cm, and above 190 cm. Different combinations of weight and height ranges correspond to different operating parameters. Operating parameters include the massage components for each location, such as the intensity of the back massage component, the intensity of the buttock massage component, the intensity of the leg massage component, the intensity of the foot massage component, and the massage mode. Massage modes include kneading mode, tapping mode, rolling mode, and airbag pressing mode. Different combinations of weight and height correspond to different massage modes. For example, a lighter and taller user corresponds to a gentle kneading mode, while a heavier and shorter user corresponds to a strong tapping mode.

[0036] For ease of understanding, this embodiment provides a specific correspondence between weight, height, and working parameters, as shown in Table 1: Table 1 To facilitate understanding of the present invention, this embodiment provides a specific application scenario to illustrate the complete execution process of this embodiment.

[0037] The user enters the room and sits on the rhythmic massage chair. As the user sits, their body weight is transmitted through the chair surface to pressure sensors. The pressure sensors detect the pressure change and output a corresponding electrical signal. The signal acquisition circuit amplifies, filters, and performs analog-to-digital conversion on the electrical signal, transmitting the digital signal to the processor. The processor initiates a weight calculation process, starting sampling after a 0.5-second delay. It continuously collects 20 pressure values ​​within 2 seconds, calculates the average of these 20 pressure values, and obtains the current weight applied to the chair surface. The processor compares the calculated weight value with a preset threshold of 20 kg. Since the user's weight is typically greater than 20 kg, the comparison result shows a weight value exceeding the threshold, and the processor determines that a user is currently on the rhythmic massage chair.

[0038] The user sends a command to start the massage via remote control. Upon receiving the command, the processor first performs a shoulder position detection. The processor controls the massage mechanism at the shoulder to move downwards along the guide rail from its starting position. During this movement, the processor continuously records the walking count. When the processor determines that the mechanism has moved to the user's shoulder position, it records the walking count at that moment. The processor then looks up the corresponding height value in a pre-stored shoulder position lookup table based on the walking count. For example, if the walking count corresponds to a height of 175 cm, the processor determines the user's height to be 175 cm.

[0039] The processor looks up the corresponding operating parameters in a pre-stored mapping table based on the user's weight and height. Assuming the user weighs 70 kg and is 175 cm tall, the mapping table shows the following operating parameters for this weight and height range: back massage component intensity set to medium, buttock massage component intensity set to low, leg massage component intensity set to medium, foot massage component intensity set to low, and massage mode set to kneading mode. The processor then sends corresponding control signals to each drive motor based on these parameters. Each drive motor adjusts its speed and direction according to the control signals, driving the corresponding massage components to perform the massage operation at the appropriate intensity and massage mode.

[0040] If the user leaves the massage chair, the pressure value detected by the pressure sensor decreases, and the weight value calculated by the processor is less than the preset threshold of 20 kg. The processor determines that the user has left the seat and controls the massage chair to enter the power saving mode, performing the massage operation with the minimum intensity or stopping the massage to save energy consumption.

[0041] In summary, the embodiments of the present invention detect the pressure generated by a user sitting on a rhythmic massage chair using a pressure sensor, calculate the user's weight based on pressure changes, determine the user's height based on shoulder position detection, and adaptively adjust the operating parameters of the rhythmic massage chair based on weight and height. This ensures that the massage intensity and massage mode match the user's body characteristics, solving the problem in the prior art that massage parameters cannot be automatically adjusted according to the user's physical condition, and improving the user's massage experience.

[0042] Example 2 Please see Figure 9 The second embodiment of the present invention provides a personalized vertical rhythmic massage control device, which is applied to a rhythmic massage chair and includes: The pressure acquisition unit 210 is used to detect the pressure acting on the surface of the rhythmic massage chair via a pressure sensor. The weight calculation unit 220 is used to obtain the current weight acting on the chair surface based on the pressure change. The weight judgment unit 230 is used to determine that there is a user on the current rhythmic massage chair when the weight is greater than a preset threshold. The height determination unit 240 is used to perform shoulder position detection after detecting the instruction to start the massage, and to determine the user's height based on the shoulder position detection result. The parameter adjustment unit 250 is used to adaptively adjust the working parameters of the rhythm massage chair according to the user's weight and height.
