[0002] Traditional car seats lack effective means to activate muscle metabolism and fail to fully utilize electrical stimulation to relieve driver muscle fatigue. This means that drivers may experience discomfort due to muscle tension and poor blood circulation after long periods of driving. Secondly, the dynamic mechanical massage function in traditional seats is merely a simple pressing effect. Lacking advanced technologies such as shape memory alloy bionic spine, magnetorheological fluid touch arrays, and pneumatic wave massage components, these seats cannot provide stable support and effective physical massage for the driver, thus failing to alleviate fatigue during driving.

[0003] Furthermore, traditional seats lag behind in sensing and control technology. The lack of multimodal sensing units prevents the seats from monitoring the driver's posture and vital signs in real time, thus hindering precise control and adjustment based on individual differences. Summary of the Invention

Therefore, the first objective of this application is to propose a seat fatigue-prevention massage system, comprising: a bioelectric stimulation module, a dynamic mechanical massage module, a multimodal sensing module, and a control module.

Detailed Implementation

[0021] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0022] The following description, with reference to the accompanying drawings, details an embodiment of the present application of a seat fatigue prevention and massage system, a seat, and a vehicle.

[0023] Figure 1 This is a schematic diagram of the structure of a seat fatigue-relieving massage system 1 according to some embodiments of this application. (Refer to...) Figure 1 The seat fatigue prevention and massage system 1 of this application includes a bioelectric stimulation module 10, a dynamic mechanical massage module 20, a multimodal sensing module 30, and a control module 40.

[0024] The bioelectric stimulation module 10 includes a flexible electrode array 11 and a dual-frequency pulse generator 12. The flexible electrode array 11 is used to electrically stimulate the human body, and the dual-frequency pulse generator 12 is used to activate the metabolism of human muscles.

[0025] The dynamic mechanical massage module 20 includes a shape memory alloy bionic spine 21, a magnetorheological fluid tentacle array 22, and a pneumatic wave massage component 23. The shape memory alloy bionic spine 21 is used to match the physiological curvature of the human spine, the magnetorheological fluid tentacle array 22 is used to enhance the stability of the seat, and the pneumatic wave massage component 23 is used to provide physical massage to the human body. Advantageously, the working sequence of the bioelectric stimulation module 10 is linked with that of the pneumatic wave massage component 23, and electrical stimulation is initiated during the airbag deflation phase. The electrical stimulation intensity I is negatively correlated with the airbag pressure value P (I=K / P, where K is a calibration coefficient).

[0026] The multimodal sensing module 30 includes a piezoresistive pressure distribution matrix 31 and a non-contact cardiac impact sensor 32. The piezoresistive pressure distribution matrix 31 is used to measure the pressure of various parts of the seat after a person sits in it, and the non-contact cardiac impact sensor 32 is used to monitor human vital signs.

[0027] The control module 40 is connected to the bioelectric stimulation module 10, the dynamic mechanical massage module 20 and the multimodal sensing module 30, so as to control the bioelectric stimulation module 10 and the dynamic mechanical unit to work based on the data monitored by the multimodal sensing module 30.

[0028] Based on the above, by combining the bioelectric stimulation module 10 and the dynamic mechanical massage module 20, the system can act on the human body from two dimensions: electrical stimulation and physical massage, effectively relieving fatigue caused by long-term driving or sitting. Bioelectric stimulation can activate muscle metabolism, while dynamic mechanical massage can relieve muscle tension. The synergistic effect of the two greatly enhances the anti-fatigue effect. The multimodal sensing module 30 can monitor information such as human posture, pressure distribution, and vital signs in real time. Based on this data, the control module 40 can accurately adjust the parameters of bioelectric stimulation and mechanical massage to provide a personalized comfort experience for each user. The addition of the magnetorheological fluid touch array 22 not only enhances the massage function of the seat but also significantly improves the stability of the seat. This design allows the seat to better maintain passenger stability in emergency situations such as sudden braking and sharp turns, thereby improving driving safety.

[0029] Thus, by combining a bioelectric stimulation module and a dynamic mechanical massage module, this application can act on the human body from two dimensions: electrical stimulation and physical massage. This effectively relieves fatigue caused by long-term driving or sitting. Bioelectric stimulation can activate muscle metabolism, while dynamic mechanical massage can relieve muscle tension. The synergistic effect of the two enhances the anti-fatigue effect. Furthermore, the addition of the magnetorheological fluid touch array not only improves the seat's massage function but also significantly enhances the seat's stability. The multimodal sensing module can monitor human posture, pressure distribution, and vital signs in real time. Based on this data, the control module can precisely adjust the parameters of bioelectric stimulation and mechanical massage, providing users with a more comfortable, safe, and convenient riding experience.

[0030] In some embodiments, the shape memory alloy bionic spine 21 includes multiple sets of nickel-titanium alloy wires, which are arranged longitudinally along the seat back and the local contraction is controlled by pulse current to achieve dynamic matching of the seat curvature with the physiological curvature of the human spine.

[0031] Specifically, because the shape memory alloy bionic spine 21 closely follows the natural curve of the spine, it provides more even and stable support. This support helps reduce the twisting and compression that the spine may suffer during prolonged sitting, thereby reducing the risk of spinal diseases, which is especially important for those who need to drive or sit for long periods. The flexibility of the shape memory alloy bionic spine 21 means that it can adapt to various sitting postures and body position changes, maintaining effective support whether sitting normally, tilting, or twisting. In addition, the nickel-titanium alloy wire, due to its excellent fatigue resistance and shape memory properties, ensures that the seat maintains good performance and comfort during long-term use, extending the seat's lifespan.

[0032] In some embodiments, refer to Figure 2The bioelectric stimulation module also includes a piezoelectric ceramic acupoint targeting unit 13, which is used to perform non-contact deep tissue stimulation on the human body.

[0033] Specifically, the piezoelectric ceramic acupoint targeting unit 13 can stimulate deep tissues of the human body through weak electrical signals generated by the piezoelectric effect without direct contact with the skin. This method avoids problems such as skin friction and allergies that may occur with traditional massage or electrical stimulation, improving safety and comfort. The piezoelectric ceramic acupoint targeting unit 13 can provide deep tissue stimulation to specific acupoints or areas of the human body. This stimulation helps promote blood circulation and metabolism, thereby relieving muscle fatigue.

[0034] In some embodiments, refer to Figure 3 The seat anti-fatigue massage system 1 also includes a predictive control module 50, which includes a fatigue prediction unit 51 and a personalized parameter unit 52. The fatigue prediction unit 51 is used to analyze the standard deviation of the RR interval and the pressure distribution entropy value in the signal monitored by the non-contact cardiac impact sensor 32, and to perform preventive massage in advance based on the analysis results. The personalized parameter unit 52 can adapt the corresponding massage mode according to the user's body shape data, body mass index, and historical fatigue curve.

[0035] Specifically, the fatigue prediction unit 51 accurately determines the user's fatigue state by analyzing the standard deviation of the RR interval (SDNN) and the pressure distribution entropy value in the signal monitored by the non-contact BCG (cardiac impaction) sensor. SDNN reflects a key indicator of heart rate variability and is closely related to the activity of the autonomic nervous system; while the pressure distribution entropy value reflects the complexity and uniformity of the pressure distribution on the seat surface, which is related to sitting comfort and fatigue level. Based on this data analysis, the predictive control module 50 can initiate preventive massage in advance, effectively reducing the accumulation of fatigue and preventing physical discomfort caused by prolonged driving or sitting.

[0036] Meanwhile, the personalized parameter unit 52 utilizes user body shape data, body mass index, and historical fatigue curves to tailor a massage method specifically for the user. This includes personalized adjustments to parameters such as massage intensity, frequency, and massage areas, ensuring that the massage effect better matches the user's physical needs and comfort. This personalized massage method not only improves user satisfaction but also helps to relieve fatigue more effectively.

[0037] Thus, the introduction of the predictive control module makes the entire massage system more intelligent. By analyzing the user's physiological signals and body shape data, the system can automatically adjust the massage parameters without the need for manual intervention by the user. This not only improves the efficiency of the system, but also allows the user to focus on driving or riding while enjoying a massage, thus improving safety and comfort.

[0038] In some embodiments, refer to Figure 4 The magnetorheological fluid tentacles 22 include a silicon capsule 221 and an electromagnetic coil 222. The silicon capsule 221 is filled with magnetorheological fluid, and the electromagnetic coil 222 is located inside the silicon capsule 221 to adjust the local hardness of the surface of the silicon capsule 221 by changing the magnetic field strength.

[0039] Specifically, the magnetorheological fluid tactile array 22 can rapidly change the surface hardness of the silicon capsule 221 by adjusting the magnetic field strength according to external stimuli or user needs. This dynamic adaptability allows the device to provide users with a more personalized tactile experience, meeting the needs of different users in different scenarios. Precise control of the electromagnetic coil 222 enables the rheological properties of the magnetorheological fluid to respond rapidly to changes in magnetic field strength. This high-precision control ensures that the device can quickly adjust its hardness when needed, providing immediate tactile feedback, thereby enhancing the user's interactive experience.

[0040] Meanwhile, the changes in magnetorheological fluids are continuous and reversible, with very low energy consumption. By precisely controlling the magnetic field strength, the desired hardness can be achieved while minimizing energy consumption and maximizing energy efficiency. This is particularly important for equipment that needs to operate for extended periods, helping to reduce operating costs and environmental impact.

[0041] In some embodiments, refer to Figure 5 The seat anti-fatigue massage system 1 also includes a cross-sensory coordination module 60, which includes a paraffin-based phase change temperature control layer 61 and a headrest atomizing fragrance device 62. The paraffin-based phase change temperature control layer 61 is used to control the temperature of the seat in contact with the human body, and the headrest atomizing fragrance device 62 is suitable for being installed in the headrest to release odor molecules.

[0042] Specifically, the paraffin-based phase change temperature control layer 61 can intelligently absorb or release heat according to changes in ambient and body temperature, thereby maintaining the seat's contact surface with the body within a suitable temperature range. This intelligent temperature control function effectively avoids overheating in summer and excessive cold in winter, providing users with a more comfortable riding experience. The headrest atomizing fragrance device 62 releases scent molecules, bringing users a pleasant olfactory experience. Different fragrances can create different atmospheres, such as fresh, tranquil, or invigorating, helping users relax, reduce stress, and further enhance the comfort and enjoyment of riding. The combination of the paraffin-based phase change temperature control layer 61 and the headrest atomizing fragrance device 62 achieves cross-sensory synergy between touch and smell. This synergy not only enhances the user's perception of seat comfort but also improves the overall riding experience through olfactory stimulation, providing users with better psychological and physiological satisfaction.

[0043] In some embodiments, continue to refer to Figure 5The cross-sensory coordination module 60 also includes a micro-vibration synchronizer 63 for generating body rhythm vibrations for the human body.

[0044] Specifically, the micro-vibration synchronizer 63 emits vibrations that match the body's natural rhythms, helping to relax muscles and relieve tension. When a user maintains the same posture for a long time or feels physically fatigued, the micro-vibration synchronizer 63 can promote blood circulation through rhythmic vibrations, reducing the burden on the body and making the user feel more comfortable and relaxed. Combined with the paraffin-based phase change temperature control layer 61 and the headrest atomizing fragrance device 62, the micro-vibration synchronizer 63 further enriches the functionality of the cross-sensory synergy module 60. The temperature control layer regulates the temperature, the fragrance device releases scents, and the vibrator provides rhythmic vibrations; all three work together to create a comprehensive sensory experience for the user. This cross-sensory synergy not only enhances the user's perception of comfort but also improves the overall user experience.

[0045] In some embodiments, continue to refer to Figure 6 The predictive control module 50 also includes a dynamic adjustment algorithm unit 53, which is used to adjust the massage parameters according to the person's sitting posture and personal parameter data.

[0046] Specifically, the dynamic adjustment algorithm unit 53 can accurately calculate and adjust massage parameters, such as massage intensity, frequency, and massage area, based on the user's personal parameter data (such as body shape, body mass index, preferences, etc.) and real-time sitting posture. This personalized customization not only improves the accuracy of the massage but also ensures the maximization of the massage effect, meeting the different comfort and health needs of users.

[0047] Advantageously, by monitoring sitting posture in real time, the dynamic adjustment algorithm unit 53 can promptly detect and correct poor posture, preventing physical discomfort or health problems caused by maintaining the same posture for extended periods. Simultaneously, personalized massage parameter settings help promote blood circulation and relieve muscle fatigue, thereby improving the user's overall comfort and health benefits. The addition of the dynamic adjustment algorithm unit 53 enables the predictive control module 50 to possess a higher level of intelligent and automated control capabilities. Users do not need to manually adjust massage parameters; the system can automatically adjust based on real-time data, greatly improving ease of use and efficiency.

[0048] Corresponding to the above embodiments, this application also proposes a seat.

[0049] See Figure 7 As shown, the seat 100 of this application includes the aforementioned seat anti-fatigue massage system 1.

[0050] Corresponding to the above embodiments, this application also proposes a vehicle.

[0051] See Figure 8 As shown, the vehicle 1000 of this application has the aforementioned seat 100.

[0052] In summary, by installing a seat fatigue-relieving massage system in the vehicle, combining a bioelectric stimulation module and a dynamic mechanical massage module, this system can act on the human body from two dimensions: electrical stimulation and physical massage, effectively relieving fatigue caused by long-term driving or sitting. Bioelectric stimulation can activate muscle metabolism, while dynamic mechanical massage can relieve muscle tension; the synergistic effect of the two greatly enhances the fatigue-relieving effect. The system's multimodal sensing module can monitor information such as human posture, pressure distribution, and vital signs in real time. Based on this data, the control module can precisely adjust the parameters of bioelectric stimulation and mechanical massage, providing a personalized comfort experience for each user. The addition of a magnetorheological fluid touch array not only enhances the seat's massage function but also significantly improves the seat's stability. This design allows the seat to better maintain passenger stability in emergency situations such as sudden braking and sharp turns, thereby improving driving safety.
