Description

Technical Field

[0001] This invention relates to the field of massage sofa technology, and in particular to an air cushion massage smart sofa. Background Technology

[0002] Massage furniture, as an important home furnishing product for relieving fatigue and promoting health, has been widely integrated into modern life. Among them, sofas with massage functions are experiencing increasing market demand due to their excellent comfort and practicality. Currently, the mainstream technology of massage sofas is mainly divided into two categories: mechanical massage sofas, which rely on mechanical transmission, and air cushion (airbag) massage sofas, which rely on changes in air pressure.

[0003] Mechanical massage sofas typically have motor-driven massage mechanisms, such as rollers and massage heads, installed inside the backrest. These mechanisms simulate the mechanical movements of human hands, such as rotation, tapping, and kneading, to provide targeted or moving deep pressure on the user's back and waist. The massage intensity is strong, and the techniques are relatively specific. However, their disadvantages are that the movement trajectory and intensity of the mechanical structure are relatively fixed, making it difficult to fully conform to the body curves of different users. This can easily cause discomfort or leave massage blind spots, resulting in an overall stiff experience that lacks a sense of enclosure and adaptability.

[0004] Air cushion massage sofas feature multiple independent airbags arranged within the sofa back and seat cushions. An air pump control system systematically inflates and deflates these airbags, using pressure changes to create wave-like, squeezing, and enveloping effects, providing gentle pressure and comprehensive support to the body. The advantages of this method are comfort, wide coverage, adaptability to different body types, and the creation of an immersive relaxation atmosphere. However, its force is dispersed, lacking the ability to precisely and deeply stimulate acupoints or muscle sore spots, and the massage's "force" and "technique" are relatively limited. Summary of the Invention

[0005] Therefore, it is necessary to provide an air-cushion massage smart sofa to address the technical problem that existing massage sofas cannot simultaneously achieve mechanical massage, flexible wrapping, and support performance.

[0006] An air-cushion massage smart sofa includes a backrest frame and an airbag structure wrapped around the backrest frame. The backrest frame includes a backrest body and a massage mechanism, which is installed on the human contact side of the backrest frame. The backrest body has an installation cavity corresponding to the massage mechanism, and the massage mechanism is installed in the installation cavity; the airbag structure covers the backrest frame and avoids the massage mechanism; the smart massage sofa also includes a control unit, which is communicatively connected to the massage mechanism and the airbag structure, and is used to coordinately control the action mode of the massage mechanism and the inflation and deflation state of the airbag structure.

[0007] In one embodiment, the massage mechanism includes a drive unit, a neck massage component, and a back massage component; the drive unit is installed in the middle of the mounting cavity; the neck massage component and the back massage component are respectively arranged at both ends of the drive unit; the drive unit is configured as a dual-head motor, with one end of its output shaft driving and connecting to the neck massage component, and the other end of its output shaft driving and connecting to the back massage component.

[0008] In one embodiment, the neck massage assembly includes a first deceleration unit and at least one neck massage head. The input end of the first deceleration unit is connected to the corresponding output end of the drive unit, and the neck massage head is mounted on the output end of the first deceleration unit. The neck massage head is provided with two neck massage protrusions having a relative height difference.

[0009] In one embodiment, the back massage assembly includes a second deceleration unit and at least one back massage head. The input end of the second deceleration unit is connected to the corresponding output end of the drive unit, and the back massage head is mounted on the output end of the second deceleration unit. The back massage head includes an eccentric rotating part and a swinging part. The eccentric rotating part is eccentrically connected to the corresponding output end of the second deceleration unit, and one end of the swinging part is connected to the edge of the eccentric rotating part, while the other end is slidably connected to the bottom wall of the mounting cavity via a rotating slide.

[0010] In one embodiment, the surface of the eccentric rotating part is provided with a plurality of first back massage protrusions arranged in a circle; the swing part is provided with a plurality of second back massage protrusions arranged in a straight line along its length; the back massage head further includes a waist massage head, which is hinged to one end of the swing part opposite to the eccentric rotating part.

[0011] In one embodiment, the waist massage head is configured with two massage rollers of different diameters, and the two massage rollers are hinged to the corresponding ends of the swing part by a connecting rod, and the two massage rollers are respectively rotatably connected to the two ends of the connecting rod.

[0012] In one embodiment, the airbag structure includes a pressure sensor matrix disposed inside the airbag structure for detecting the pressure distribution in various parts of the body; the control unit dynamically adjusts the internal pressure of the airbag structure in the corresponding area based on the feedback data from the pressure sensor matrix.

[0013] In one embodiment, the air cushion massage smart sofa further includes a biosignal monitoring module, which includes a non-contact millimeter-wave radar sensor and / or an infrared thermal imaging sensor for monitoring the user's heart rate, respiratory rate, and body surface temperature distribution; the control unit is configured to automatically select or adjust a pre-stored massage and airbag collaborative working program based on the data from the biosignal monitoring module.

[0014] In one embodiment, the air cushion massage smart sofa also includes a communication module and a user terminal interface; the control unit connects to the user's mobile terminal or cloud server through the communication module to receive customized massage programs, upload the user's massage and physiological data to generate health reports, or link with other smart home devices.

[0015] A method for controlling the air-cushion massage smart sofa includes the following steps: S1. Receive user instructions or automatically trigger massage tasks according to preset conditions; S2. Based on the massage task, control the drive unit of the massage mechanism to start, and drive the neck massage component and / or back massage component to work in a preset mode; S3. Based on the massage task and the feedback data obtained in real time from the pressure sensor matrix and / or biosignal monitoring module, control the inflation and deflation timing and pressure value of the airbag structure so that the airbag support state is coordinated with the mechanical massage action.

[0016] In one embodiment, step S3 specifically includes: identifying the user's current sitting or lying posture and the pressure concentration area based on the data from the pressure sensor matrix; dynamically adjusting the pressure of the airbag structure in the corresponding area to even out the pressure distribution; and locally fine-tuning the airbag pressure as the mechanical massage head passes through to optimize the contact depth and intensity of the massage head.

[0017] In one embodiment, the method for controlling the air cushion massage smart sofa further includes step S4: recording the user's usage preferences for different massage and airbag combination modes and the physiological indicator improvement data corresponding to the biosignal monitoring module; analyzing the recorded data through machine learning algorithms to establish a personalized comfort and effectiveness model for the user; and automatically recommending or fine-tuning the collaborative working parameters of massage and airbags in subsequent use based on the model.

[0018] In one embodiment, the method for controlling the air cushion massage smart sofa further includes step S5: calculating the ideal massage path for the neck, back, and waist based on the user's height and weight information or the location of key body points identified by a pressure sensor matrix; and generating the speed and steering commands of the drive unit and the coordination strategy of the airbag structure on the corresponding trajectory based on the ideal massage path.

[0019] The aforementioned smart air-cushion massage sofa integrates the airbag structure with the massage mechanism through coordinated control of the control unit. When the mechanical massage head performs deep therapy techniques such as "pounding" and "kneading," the surrounding airbags inflate simultaneously to provide support, increasing body stability and allowing the mechanical force to be more effectively transmitted to deep muscles. Conversely, when the airbags perform soothing massage techniques such as "waves" and "pressing," the mechanical massage head remains stationary or moves slightly to avoid interference. This alternation or synchronization of "rigid and precise stimulation" and "soft, enveloping pressure" simulates a richer and more human-like comprehensive massage technique, significantly improving therapeutic effects and comfort. The airbag structure covers the backrest frame and avoids obstructing the massage mechanism. This design ensures that the movement path of the massage mechanism (mechanical massage head) is not interfered with by the airbags, allowing it to always operate precisely along a preset mechanical trajectory, ensuring accurate stimulation of acupoints and muscle groups. Simultaneously, the control unit can dynamically adjust the inflation and deflation of the airbags based on preset programs or sensor feedback. For example, when enhanced lumbar support is needed, the lumbar airbag inflates, lifting the body and allowing the back massage head to more closely conform to the lumbar curve. This combination of mechanical positioning and airbag posture adjustment achieves self-adaptation to human posture, ensuring effective massage in different sitting / lying positions.

[0027] Please see Figures 1 to 3 The present invention discloses an air cushion massage smart sofa, which includes a backrest frame 1 and an airbag structure (not shown) wrapped around the backrest frame 1. The backrest frame 1 includes a backrest body 11 and a massage mechanism 12, which is installed on the human body contact side of the backrest frame 1. The backrest body 11 is provided with a mounting cavity 11a corresponding to the massage mechanism 12, and the massage mechanism 12 is installed in the mounting cavity 11a. The airbag structure covers the backrest frame 1 and avoids the massage mechanism 12. The intelligent massage sofa also includes a control unit, which is communicatively connected to both the massage mechanism 12 and the airbag structure, and is used to coordinately control the action mode of the massage mechanism 12 and the inflation and deflation state of the airbag structure. This invention, by introducing a control unit to coordinate the control of both, breaks through the limitation of the single function of traditional massage sofas, thereby producing a synergistic effect of combining rigid mechanical massage with flexible air pressure wrapping.

[0028] The massage mechanism 12 includes a drive unit 121, a neck massage component, and a back massage component. The drive unit 121 is installed in the middle of the mounting cavity 11a. The neck massage component and the back massage component are respectively arranged at both ends of the drive unit 121. The drive unit 121 is configured as a dual-head motor, with one end output shaft driving the neck massage component and the other end output shaft driving the back massage component. The drive unit 121 uses a single dual-head motor as the central power source, simultaneously driving the neck and back massage components, simplifying the transmission structure, reducing costs and failure rates, and facilitating the synchronous and coordinated movement of neck and back massage.

[0029] The neck massage assembly includes a first deceleration unit 122 and at least one neck massage head 123. The input end of the first deceleration unit 122 is connected to the corresponding output end of the drive unit 121, and the neck massage head 123 is mounted on the output end of the first deceleration unit 122. The neck massage head 123 is provided with two neck massage protrusions with a relative height difference. The neck massage assembly adapts to the required rotation speed and torque through the deceleration unit, and the design of the massage protrusions with a relative height difference can simulate uneven force changes such as "kneading" and "acupressure" during rotation, better conforming to the curve of the human neck and improving the realism and comfort of the massage.

[0030] The back massage assembly includes a second deceleration unit 124 and at least one back massage head 125. The input end of the second deceleration unit 124 is connected to the corresponding output end of the drive unit 121, and the back massage head 125 is mounted on the output end of the second deceleration unit 124. The back massage head 125 includes an eccentric rotating part 125a and a swinging part 125b. The eccentric rotating part 125a is eccentrically connected to the corresponding output end of the second deceleration unit 124, and one end of the swinging part 125b is connected to the edge of the eccentric rotating part 125a, while the other end is slidably connected to the bottom wall of the mounting cavity 11a via a rotating slide 125c. The eccentric rotation of the eccentric rotating part 125a combined with the sliding of the swinging part 125b enables the end of the massage head to generate a complex three-dimensional motion trajectory, thereby simulating various compound massage techniques such as "pushing," "grasping," and "kneading" by human hands, significantly improving the diversity and depth of back massage.

[0031] The eccentric rotating part 125a has a plurality of first back massage protrusions arranged in a circular pattern on its surface; the swinging part 125b has a plurality of second back massage protrusions arranged in a straight line along its length; the back massage head 125 also includes a waist massage head, which is hinged to one end of the swinging part 125b facing away from the eccentric rotating part 125a. The straight-arranged protrusions can achieve a "scraping" effect along the spine during the swinging process; the hinged waist massage head can adaptively conform to the curvature of the lumbar spine, and roll and press the waist while following the swing, achieving a smooth and continuous massage coverage from the back to the waist.

[0032] The waist massage head is configured with two massage rollers 125d of different diameters, and the two massage rollers 125d are hinged to the corresponding ends of the swing part 125b via a connecting rod 125e. The two massage rollers 125d are respectively rotatably connected to the two ends of the connecting rod 125e. The two massage rollers 125d of different diameters can generate differentiated pressure and contact area when rolling on the waist, simulating the pressing sensation of different finger joints; the hinge of the connecting rod 125e allows the two rollers to adapt to the curvature of the waist, ensuring uniform force and avoiding excessive pressure at a single point.

[0033] The airbag structure includes a pressure sensor matrix disposed inside the airbag structure to detect the pressure distribution in different parts of the body. The control unit dynamically adjusts the internal pressure of the airbag structure in corresponding areas based on feedback data from the pressure sensor matrix. The airbag structure uses the pressure sensor matrix to sense the user's posture and body pressure distribution in real time. The control unit intelligently adjusts the airbag pressure accordingly, achieving dynamic adaptive body support, effectively preventing poor local blood circulation, and providing a stable body fit for mechanical massage, thus improving massage precision.

[0034] The air-cushion massage smart sofa also includes a biosignal monitoring module, which comprises a non-contact millimeter-wave radar sensor and / or an infrared thermal imaging sensor to monitor the user's heart rate, respiratory rate, and body surface temperature distribution. The control unit is configured to automatically select or adjust a pre-stored massage and airbag collaborative working program based on the data from the biosignal monitoring module. The air-cushion massage smart sofa acquires real-time physiological data from the user through non-contact sensors, enabling the sofa to intelligently determine the user's fatigue, tension, or relaxation state and automatically switch to the most suitable physiotherapy mode, achieving an intelligent leap from "passive response operation" to "active health intervention."

[0035] The air-cushion massage smart sofa also includes a communication module and a user terminal interface. The control unit connects to the user's mobile terminal or cloud server through the communication module to receive customized massage programs, upload the user's massage and physiological data to generate health reports, or link with other smart home devices. Through its connection with external devices and the cloud, the air-cushion massage smart sofa achieves remote functional expansion, deep customization of personalized solutions, long-term tracking of health management, and integration of smart scenarios, upgrading the sofa from an independent product into a smart node in a personal health management ecosystem.

[0036] A method for controlling the air-cushion massage smart sofa includes the following steps: S1. Receive user instructions or automatically trigger massage tasks according to preset conditions; S2. Based on the massage task, control the drive unit 121 of the massage mechanism 12 to start, and drive the neck massage component and / or back massage component to work in a preset mode. S3. Based on the massage task and the feedback data obtained in real time from the pressure sensor matrix and / or biosignal monitoring module, control the inflation and deflation timing and pressure value of the airbag structure so that the airbag support state is coordinated with the mechanical massage action.

[0037] Step S3 specifically includes: identifying the user's current sitting or lying posture and the pressure concentration area based on the data from the pressure sensor matrix; dynamically adjusting the pressure of the airbag structure in the corresponding area to even out the pressure distribution; and locally fine-tuning the airbag pressure as the mechanical massage head passes through to optimize the contact depth and intensity of the massage head.

[0038] The method for controlling the air cushion massage smart sofa further includes step S4: recording the user's usage preferences for different massage and airbag combination modes and the physiological indicator improvement data corresponding to the biosignal monitoring module; analyzing the recorded data through machine learning algorithms to establish a personalized comfort and effectiveness model for the user; and automatically recommending or fine-tuning the collaborative working parameters of massage and airbags in subsequent use based on the model.

[0039] The method for controlling the air cushion massage smart sofa further includes step S5: calculating the ideal massage path for the neck, back and waist based on the user's height and weight information or the location of key body points identified by the pressure sensor matrix; and generating the speed and steering commands of the drive unit 121 and the corresponding coordination strategy of the airbag structure on the trajectory based on the ideal massage path.

[0040] In summary, the air-cushion massage smart sofa disclosed in this invention organically integrates the airbag structure with the massage mechanism through the coordinated control of the control unit. When the mechanical massage head performs deep physiotherapy such as "pounding" and "kneading," the surrounding airbags can simultaneously inflate to provide support, increasing body stability and allowing the mechanical force to be transmitted more effectively to deep muscles. When the airbags perform soothing massages such as "waves" and "pressing," the mechanical massage head can remain still or move slightly to avoid interference. This alternation or synchronization of "rigid and precise stimulation" and "soft wrapping and pressing" can simulate richer and more human-like comprehensive massage techniques, significantly improving the therapeutic effect and comfort. The airbag structure covers the backrest frame and avoids the massage mechanism. This design ensures that the movement path of the massage mechanism (mechanical massage head) is not interfered with by the airbags, and it can always run precisely according to the preset mechanical trajectory, ensuring accurate stimulation of acupoints and muscle groups. At the same time, the control unit can dynamically adjust the inflation and deflation of the airbags according to preset programs or sensor feedback. For example, when enhanced lumbar support is needed, the lumbar airbag inflates, lifting the body and allowing the back massage head to more closely conform to the lumbar curve. This combination of mechanical positioning and airbag posture adjustment achieves self-adaptation to human posture, ensuring effective massage in different sitting / lying positions.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
