It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments in any suitable manner.

[0061] Please refer to the following: Figures 1-4 The massage device provided in this application embodiment will now be described. The massage device includes: a massage control module 200, a hinge assembly 500, and two massage modules 100. The massage control module 200 includes a first housing, with first hinge seats 2021 provided on both sides of the first housing. Each massage module 100 is provided with a second hinge seat 1581. The second hinge seats 1581 of the two massage modules 100 are hinged to the first hinge seats 2021 on both sides of the first housing through the hinge assembly 500. The massage control module 200 is used to control the two massage modules 100 to perform massage actions.

[0062] For example, the first housing includes an upper housing 201 of the control module and a lower housing 202 of the control module, with a first hinge seat 2021 provided on each side of the lower housing 202 of the control module.

[0063] See Figure 4 In this embodiment, the hinge assembly 500 includes a hinge shaft 510, a retaining ring 520, a pin 530, and a ball bearing 540. The first hinge seat 2021 has a shaft hole, and the second hinge seat 1581 also has a shaft hole. The shaft holes of both are coaxial, and the ball bearing 540 is disposed within the shaft hole of the second hinge seat 1581. The hinge shaft 510 is inserted into the shaft holes of the first hinge seat 2021 and the second hinge seat 1581, and the retaining ring 520 limits the movement of both ends of the hinge shaft 510. The first hinge seat 2021 is provided with a first pin hole 2022, and the extension direction of the first pin hole 2022 can be perpendicular to the extension direction of the shaft hole on the first hinge seat 2021; the hinge shaft 510 is provided with a second pin hole 511 corresponding to the position of the first pin hole 2022, and the extension direction of the second pin hole 511 can be perpendicular to the extension direction of the shaft hole of the second hinge seat 1581; the pin 530 is inserted into the first pin hole 2022 and the second pin hole 511 to realize the hinge connection between the massage module 100 and the massage control module 200.

[0064] When the massage device of this embodiment is subjected to pressure, the two massage modules 100 rotate relative to the massage control module 200 under the action of the hinge assembly 500. It is easy to understand that since the pin 530 is inserted into the first pin hole 2022 and the second pin hole 511, the hinge shaft 510 does not rotate relative to the first housing, while the outer ring of the massage module 100 and the ball bearing 540 rotates relative to the massage control module 200.

[0065] like Figure 5 The image shows the massage device in its installed state (i.e., its original state); when the user's back is narrow, the massage device adapts to... Figure 6 As shown in the diagram, the angle between the two massage modules 100 is relatively small; when the user's back is wider, the massage device adapts accordingly. Figure 7 As shown in the diagram, the angle between the two massage modules 100 is relatively large.

[0066] In this embodiment, the two massage modules 100 can rotate relative to the massage control module 200 through a hinge assembly. Thus, when the massage device is under pressure, the two massage modules 100 can synchronously and adaptively adjust their included angle to better fit the user's body contour, thereby allowing the massage force to be transmitted to the human body more accurately and significantly improving the massage effect.

[0067] As an optional implementation, see [link to implementation details]. Figure 8 The massage module 100 includes: a drive mechanism 150 having a massage output shaft 1551; a massage roller assembly 110 being driven by the massage output shaft 1551, the massage output shaft 1551 driving the massage roller assembly 110 to rotate under the drive of the drive mechanism 150; and an airbag ejection mechanism 130 including an airbag 133 and a guide assembly, the airbag 133 being driven by the massage roller assembly 110, the guide assembly providing motion guidance for the massage roller assembly 110 to eject or retract along the axial direction of the massage output shaft 1551; the airbag 133 is used to drive the massage roller assembly 110 to eject or retract along the axial direction of the massage output shaft 1551.

[0068] Specifically, the drive mechanism 150 provides rotational power to the massage roller assembly 110, and the drive mechanism 150 includes a massage output shaft 1551. As a power transmission component, the massage output shaft 1551 transmits the rotational power generated by the drive mechanism 150 to the massage roller assembly 110, thereby driving the massage roller assembly to rotate to achieve the massage action.

[0069] The drive mechanism 150 includes a housing and a power source and a transmission assembly located within the housing. The output shaft of the power source meshes with the input shaft of the transmission assembly. The output shaft of the transmission assembly is a massage output shaft 1551, which is at least partially located outside the housing.

[0070] Optionally, the housing includes an upper gearbox housing 157 and a lower gearbox housing 158, which are assembled to form a space for accommodating the power source and transmission components. Optionally, a second hinge seat 1581 is disposed on the lower gearbox housing 158.

[0071] Optionally, the power source can be a brushless motor 151, which is installed inside the housing and serves as the power output source for the drive mechanism 150. A worm gear 152 is provided on the output shaft of the brushless motor 151.

[0072] The transmission assembly includes multiple gears, as exemplified, see [link to example]. Figure 5 The transmission assembly includes a first gear 153, a second gear 154, and a third gear 155, whose diameters increase sequentially and mesh with each other. The shaft of the first gear 153 is the input shaft, which meshes with the worm gear 152. The shaft of the third gear 155 is the massage output shaft 1551 (the massage output shaft 1551 can be fixed to the third gear 155 by injection molding). A bearing is fitted on the massage output shaft 1551, and the outer ring of the bearing is fixed inside the lower housing 158 of the gearbox. Speed ​​reduction is achieved through multi-stage gear meshing, realizing speed regulation and torque matching of the power. Finally, the optimized power is transmitted to the massage roller assembly 110 by the output shaft of the transmission assembly (i.e., the massage output shaft 1551).

[0073] As another alternative implementation, the drive mechanism 150 includes a housing and a brushless motor 151. The output end of the brushless motor 151 is provided with a massage output shaft 1551. The brushless motor 151 is located inside the housing, and the massage output shaft 1551 is located outside the housing.

[0074] The airbag 133 has a flexible cavity structure. When the airbag 133 inflates, it applies a thrust to the massage roller assembly 110, causing the massage roller assembly 110 to extend along the axial direction of the massage output shaft 1551. When the airbag 133 deflates, it releases the thrust, and the massage roller assembly 110 retracts along the axial direction of the massage output shaft 1551. The guide assembly provides directional constraints for the movement of the massage roller assembly 110, allowing the massage roller assembly 110 to move along the axial direction of the massage output shaft 1551.

[0075] The massage roller assembly 110 is a component that acts on the human body. The massage roller assembly 110 is connected to the massage output shaft 1551 and rotates around the axis of the massage output shaft 1551 under the drive of the drive mechanism 150 to realize mechanical massage action. Under the drive of the airbag 133, it makes an outward or retracting movement along the axial direction of the massage output shaft 1551 to adjust the contact depth with the human body and adapt to different massage intensity requirements.

[0076] For example, the operation of the massage module 100 in this embodiment is as follows:

[0077] When a massage is needed, an external air source inflates the airbag 133, causing it to expand and push the massage roller assembly 110 outwards along the axis of the massage output shaft 1551 until the massage rollers 111 apply pressure to the body. Simultaneously, the drive mechanism 150 activates, causing the massage output shaft 1551 to rotate the massage roller assembly 110, applying pressure to the body and achieving the massage action. When the massage is no longer needed, the airbag 133 contracts, and the massage roller assembly 110 retracts along the axis of the massage output shaft 1551.

[0078] In this embodiment, the massage output shaft 1551 of the drive mechanism 150 is connected to the massage roller assembly 110 via a transmission connection. The rotational power can be directly transmitted to the massage roller 111 through a rigid transmission path, making the output of the massage force closer to the control command and improving the accuracy of the force control.

[0079] As an optional implementation, the massage output shaft 1551 passes through the through hole provided on the guide assembly and the through hole provided on the airbag 133; the guide assembly is provided with an accommodating space for accommodating the airbag 133.

[0080] Specifically, the guide assembly is provided with a through hole, the extension direction of which is the same as the axial direction of the massage output shaft 1551. The massage output shaft 1551 passes through the through hole provided on the guide assembly, and a gap is formed between the inner wall of the through hole on the guide assembly and the outer wall of the massage output shaft 1551.

[0081] The airbag 133 is located within the accommodating space formed inside the guide assembly. The shape and size of the accommodating space are designed according to the expansion / contraction range of the airbag 133, providing both installation positioning for the airbag 133 and restricting the expansion direction of the airbag 133—ensuring that the airbag 133 expands primarily along the axial direction of the massage output shaft 1551, making the expansion force of the airbag 133 more concentrated and accurate in acting on the massage roller assembly 110. Thus, the accommodating space expands or contracts along the axial direction of the massage output shaft 1551 under the drive of the airbag 133.

[0082] It should be noted that the airbag 133 does not contact the massage output shaft 1551 to avoid wear on the airbag 133 during the rotation of the massage output shaft 1551. There may be one or more airbags 133 in the accommodating space.

[0083] In this embodiment, the accommodating space enclosed by the guide component and the massage output shaft 1551 restricts the radial disordered expansion of the airbag 133, making the expansion force of the airbag 133 more concentrated in the axial direction, thereby improving the driving efficiency of the airbag 133 and the accuracy of motion guidance. In addition, through the design of "through hole + accommodating space", the airbag 133, the guide component and the massage output shaft 1551 are integrated and installed in a limited space, reducing the space occupied by components and better adapting to modular installation requirements.

[0084] As an optional implementation, see [link to implementation details]. Figure 8 The guiding assembly includes: a protective cover 131, a support plate guide sleeve 132, a support plate 134, a guide rod 136, and an elastic element; the protective cover 131 and the support plate guide sleeve 132 are mounted on the housing of the drive mechanism 150; the support plate 134 is sleeved on the support plate guide sleeve 132, and a first guiding structure is provided between the support plate 134 and the support plate guide sleeve 132 to prevent the support plate 134 from rotating relative to the support plate guide sleeve 132; the support plate 134 is slidably disposed on the support plate guide sleeve 132 along the axial direction of the massage output shaft 1551 through the first guiding structure; the massage output shaft 1551 passes through the through holes in the protective cover 131, the support plate guide sleeve 132, and the support plate 134, and is connected to the guide rod 136. The guide rod 136 is connected at one end, and a limit block 1361 is provided at the other end. The massage roller assembly 110 is sleeved on the guide rod 136 and located between the limit block 1361 and the support plate 134. A second guide structure is provided between the guide rod 136 and the massage roller assembly 110 to prevent the massage roller assembly 110 from rotating relative to the guide rod 136. The massage roller assembly 110 is slidably disposed on the guide rod 136 along the axial direction of the massage output shaft 1551 through the second guide structure. An elastic element is sleeved on the guide rod 136, and one end of the elastic element abuts against the limit block 1361, and the other end of the elastic element abuts against the massage roller assembly 110. The airbag 133 is located in the accommodating space formed by the support plate 134, the support plate guide sleeve 132, and the protective cover 131.

[0085] Specifically, the protective cover 131 is a rigid frame structure, which, together with the support plate guide sleeve 132, serves as the basic support component of the guide assembly. The protective cover 131 and the support plate guide sleeve 132 can be fixedly mounted on the housing of the drive mechanism 150 by screws. The protective cover 131 extends along the axial direction of the massage output shaft 1551, and the inner wall of the protective cover 131 restricts the radial expansion of the airbag 133, so that the airbag 133 can only extend along the axial direction of the massage output shaft 1551.

[0086] The support plate guide sleeve 132 extends axially along the massage output shaft 1551, and has a through-hole inside, serving as a passage for the massage output shaft 1551 to pass through, while also providing a guiding foundation for the installation of the support plate 134. The support plate guide sleeve 132 includes a guide tube 1321 extending along the axial direction of the massage output shaft 1551, and a first slide rail 1322 extending along the axial direction of the massage output shaft 1551 is provided on the outer wall of the guide tube 1321.

[0087] The support plate 134 is sleeved on the outer periphery of the guide tube 1321 of the support plate guide sleeve 132 and can slide freely along the axial direction of the support plate guide sleeve 132. The support plate 134 has a through hole in the middle for the massage output shaft 1551 to pass through. The inner wall of the through hole of the support plate 134 has a first slide groove 1341 that matches the first slide rail 1322. The first slide rail 1322 and the first slide groove 1341 form a first guide structure.

[0088] The first guide structure only allows the support plate 134 to translate along the axial direction of the massage output shaft 1551, restricting the rotational movement of the support plate 134 relative to the support plate guide sleeve 132, so that the force transmitted by the support plate 134 acts on the massage roller assembly 110 along the axial direction of the massage output shaft 1551.

[0089] The end of the massage output shaft 1551 is fixedly connected to one end of the guide rod 136 (e.g., by screw locking, interference fit with the shaft hole, or keyway fit), so that the rotational power of the drive mechanism 150 can be directly transmitted to the guide rod 136 through the massage output shaft 1551, thereby driving the massage roller assembly 110 to rotate. The other end of the guide rod 136 away from the massage output shaft 1551 is integrally formed or fixedly mounted with a limiting block 1361. The outer diameter of the limiting block 1361 is larger than the outer diameter of the guide rod 136, forming a radial protrusion structure for axially limiting the elastic element.

[0090] For example, the outer wall of the guide rod 136 is provided with a second slide rail, and the massage roller assembly 110 is provided with a second slide groove at the corresponding position, or the guide rod 136 adopts a square cross section and the corresponding hole of the massage roller assembly 110 is a square hole; the second slide rail and the second slide groove, or the square guide rod 136 and the square hole form a second guide structure.

[0091] The second guide structure restricts the rotational movement of the massage roller assembly 110 relative to the guide rod 136, but allows the massage roller assembly 110 to slide freely along the axial direction of the guide rod 136, so that the massage roller assembly 110 can rotate synchronously with the guide rod 136 and perform push-out / retract actions along the axial direction.

[0092] Optionally, a spring 135 is selected as the elastic element. The spring 135 is sleeved on the outer periphery of the guide rod 136. One end of the spring 135 abuts against the limiting block 1361 on the guide rod 136, and the other end of the spring 135 abuts against the end face of the massage roller assembly 110. When the airbag 133 expands and pushes the massage roller assembly 110 along the guide rod 136 in a direction away from the drive mechanism 150, the spring 135 is compressed and stores elastic potential energy. When the airbag 133 contracts, the spring 135 releases its potential energy, assisting the massage roller assembly 110 in resetting along the guide rod 136 in a direction closer to the drive mechanism 150, reducing the lag in the resetting action.

[0093] Specifically, the airbag 133 is confined within an accommodating space enclosed by the support plate 134, the support plate guide sleeve 132, and the protective cover 131: the protective cover 131 forms the outer peripheral boundary of the accommodating space, the support plate 134 forms the axial boundary of the accommodating space near the massage roller assembly 110, and the guide tube 1321 of the support plate guide sleeve 132 forms the central axis boundary of the accommodating space.

[0094] It is easy to understand that in the guide assembly, the protective cover 131, the support plate guide sleeve 132, and the support plate 134 do not rotate with the massage output shaft 1551, while the guide rod 136 and the elastic element rotate with the massage output shaft 1551.

[0095] In this embodiment, the first guide structure restricts the rotation of the support plate 134, and the second guide structure restricts the rotation of the massage roller assembly 110 relative to the guide rod 136. With the axial constraint of the guide rod 136, the multi-guide design greatly reduces the radial offset during the ejection / retraction process, so that the massage roller assembly 110 will not drive the airbag 133 to rotate during the rotation, thereby improving the accuracy of the force transmitted from the expansion or contraction of the airbag 133 to the massage output shaft 1551.

[0096] As an optional implementation, see [link to implementation details]. Figure 8 The massage roller assembly 110 includes a ball bearing 113, a turntable 112, and a massage roller 111 mounted on the turntable 112. The turntable 112 is sleeved on the guide rod 136. A second guide structure is disposed on the turntable 112 and the guide rod 136, and the second guide structure is located between the turntable 112 and the guide rod 136. A plurality of ball bearing holes 1122 are provided on the side of the turntable 112 near the support plate 134. Part of the spherical surface of the ball bearing 113 is located in the ball bearing hole 1122, and the ball bearing 113 abuts against the side of the support plate 134 away from the airbag 133.

[0097] The turntable 112 is a supporting component of the massage roller assembly 110. Its central area has a through hole that mates with the guide rod 136. A second guide structure is provided between the inner wall of the through hole and the guide rod 136. Multiple ball bearing holes 1122 are provided on the surface of the turntable 112 near the support plate 134. The ball bearing holes 1122 are circumferentially distributed along the through hole in the center of the turntable 112, providing installation and positioning space for the balls 113.

[0098] The ball bearing 113 is installed in the ball bearing hole 1122 of the turntable 112, with a portion of its spherical surface protruding from the surface of the turntable 112 and abutting against the side of the support plate 134 away from the airbag 133. When the airbag 133 pushes the support plate 134 to move axially along the massage output shaft 1551, the support plate 134 transmits thrust to the turntable 112 through the ball bearing 113. When the massage output shaft 1551 drives the guide rod 136 and the turntable 112 to rotate, the ball bearing 113 rolls between the support plate 134 and the turntable 112.

[0099] Optionally, a rotating shaft 1121 is fixed on the turntable 112, and a bearing or roller sleeve 114 is installed on the massage roller 111. The massage roller 111 is mounted on the rotating shaft 1121 via the bearing (not shown in the figure) or the roller sleeve 114, and is fixed to the turntable 112 by the roller fixing member 115. The roller fixing member 115 can be a nut or a snap ring, which is fixed to the end of the rotating shaft 1121 by screws or snap rings, axially locking the roller sleeve 114 and the massage roller 111 on the turntable 112 to prevent the massage roller 111 from loosening or falling off during rotation or ejection / retraction.

[0100] The massage roller 111 is a massage component that acts on the human body. It can be made of elastic material (such as rubber) and the surface can be provided with raised texture to enhance the massage effect.

[0101] In this embodiment, the cooperation between the second guide structure and the ball bearing 113 enables the turntable 112 to both stably transmit rotational power and slide along the guide rod 136.

[0102] As an optional implementation, see [link to implementation details]. Figure 9 The massage control module 200 also includes a control component, an air passage 206, a first solenoid valve 207, a second solenoid valve 208, and a third solenoid valve 209 installed in the first housing. The air passage 206 includes a main pipe 2061 and a first branch pipe 2062 and a second branch pipe 2063 respectively connected to the main pipe 2061. The first branch pipe 2062 and the second branch pipe 2063 are respectively connected to the airbags 133 of the two massage modules 100. The first solenoid valve 207 is disposed on the main pipe 2061 to stabilize the air pressure in the main pipe 2061. The second solenoid valve 208 is disposed on the first branch pipe 2062 to allow airflow in the first branch pipe 2062 to pass through, cut off, or discharge. The third solenoid valve 209 is disposed on the second branch pipe 2063 to allow airflow in the second branch pipe 2063 to pass through, cut off, or discharge. The control component is electrically connected to the first solenoid valve 207, the second solenoid valve 208, and the third solenoid valve 209 respectively.

[0103] Specifically, the first housing is used to house the control components, the first solenoid valve 207, the second solenoid valve 208, the third solenoid valve 209, and a portion of the pneumatic pipeline 206.

[0104] The control component can be a PCB board 203, which is electrically connected to the first solenoid valve 207, the second solenoid valve 208, and the third solenoid valve 209 respectively. It can receive external commands or sensor signals (such as air pressure signals) and output electrical signals to control the on / off state of each solenoid valve, thereby achieving precise control of the air circuit.

[0105] The first solenoid valve 207 is installed on the main pipe 2061, serving as the main air source switch and stabilizing the air pressure within the main pipe 2061. It controls the on / off supply of gas from the external air source to the entire airway pipe 206, enabling overall air source control for the two massage modules 100 airbags 133. The second solenoid valve 208 is installed on the first branch pipe 2062, controlling the on / off or leakage of air in the first branch pipe 2062, allowing for individual adjustment. Figure 9 The inflation and deflation volume of the airbag 133 in the left-side massage module 100; the third solenoid valve 209 is located on the second branch pipe 2063 to control the air passage opening and closing of the second branch pipe 2063 and adjust it independently. Figure 9 The inflation and deflation of the airbag 133 in the right-side massage module 100.

[0106] As an optional implementation, see [link to implementation details]. Figure 10 The massage control module 200 also includes a first air pressure sensor 204 and a second air pressure sensor 205 that are electrically connected to the control component. The first air pressure sensor 204 is used to collect the air pressure value in the first branch pipe 2062, and the second air pressure sensor 205 is used to collect the air pressure value in the second branch pipe 2063.

[0107] The first pressure sensor 204 is installed on the first branch pipe 2062 inside the first housing. The detection end of the first pressure sensor 204 is connected to the internal air passage of the first branch pipe 2062, and is used to collect the gas pressure value inside the first branch pipe 2062. The first pressure sensor 204 is electrically connected to the control component via a wire, and can transmit the collected pressure signal to the control component. Figure 9 The air pressure adjustment of the airbag 133 in the left-side massage module 100 provides feedback. Similarly, the second air pressure sensor 205 provides... Figure 9 The air pressure adjustment of the airbag 133 in the right-side massage module 100 provides feedback.

[0108] After receiving real-time air pressure data from the first air pressure sensor 204 and the second air pressure sensor 205, the control component compares it with a preset target air pressure value (such as the air pressure value corresponding to the massage intensity set by the user).

[0109] When the air pressure in the first branch pipe 2062 is lower than the target value, the control component controls the first solenoid valve 207 and the second solenoid valve 208 to remain open, and inflates the left airbag 133 through an external air source until the first air pressure sensor 204 detects that the air pressure has reached the target value. Then the control component controls the solenoid valve to close to maintain the air pressure.

[0110] When it is necessary to reduce the massage intensity on the left side, the control component controls the second solenoid valve 208 to switch to the deflation state. The gas in the left airbag 133 is discharged through the first branch pipe 2062. The first air pressure sensor 204 monitors the air pressure drop process in real time until the preset lower air pressure value is reached, and then the deflation channel is closed.

[0111] The air pressure adjustment process of the right massage module 100 is the same as that of the left side, and is fed back in real time by the second air pressure sensor 205. The control component controls the operation by regulating the third solenoid valve 209.

[0112] In this embodiment, the first air pressure sensor 204 and the second air pressure sensor 205 collect the air pressure data of the corresponding branch pipe in real time, enabling the control component to accurately sense the actual pressure state of the airbag 133, reduce air pressure deviation caused by air source fluctuations or air leakage, and improve the control accuracy of massage intensity.

[0113] As an optional implementation, the massage device further includes: an air pump module 300, which is mounted on the massage control module 200 or any of the massage modules 100; the air pump module 300 is electrically connected to the control component.

[0114] The air pump module 300 includes an air pump 303, an upper air pump housing 301, and a lower air pump housing 302. The air pump 303 is located in the cavity formed by the upper air pump housing 301 and the lower air pump housing 302.

[0115] For example, see Figure 5 In this embodiment, the air pump module 300 is mounted on the upper housing 157 of the massage chamber. It is easily understood that the air pump module 300 can also be mounted on the first housing of the massage control module 200, or it can be located inside the first housing. There can be one air pump module 300, which inflates the airbags 133 within the two massage modules 100, or there can be one air pump module 300 corresponding to each massage module 100.

[0116] The control component can control the air pump module 300 to inflate the airbag 133, so that the airbag 133 drives the massage roller assembly 110 to move along the axial direction of the massage output shaft 1551. Therefore, this embodiment does not require an external air source to supply air to the airbag 133, and has a high degree of integration.

[0117] See Figures 11-12 This application also provides a vehicle seat 400, including at least one of a seat cushion 410, a backrest 420, and a headrest 430, wherein at least one of the seat cushion 410, the backrest 420, and the headrest 430 is provided with at least one massage device as described in any of the above embodiments.

[0118] It is easy to understand that the massage device can be installed inside the seat cushion 410 to massage the buttocks, inside the backrest 420 to massage the back, or inside the headrest 430 to massage the head.

[0119] As an optional implementation, see [link to implementation details]. Figure 12 The backrest 420 includes a backrest frame 426, a spring frame 425, a sponge 422, and a face mask 421. The sponge 422 is provided with a clearance through hole 4221 for the massage roller assembly 110 to be pushed out or retracted. The massage roller assembly 110 is located in the clearance through hole 4221. The massage device is mounted on the spring frame 425 by a fixing plate 156, and the spring frame 425 is mounted on the backrest frame 426.

[0120] The backrest frame 426 is the basic support structure for the backrest 420. It can be made of high-strength steel welded into a rectangular frame. The backrest frame 426 has multiple mounting positions for connecting the spring frame 425. The bottom of the backrest frame 426 is hinged to the seat cushion 410.

[0121] The spring frame 425 is an elastic support component, which is fixed to the inside of the backrest frame 426 by the buckle 424 and the locking sleeve 423.

[0122] The sponge 422 is fixed to the backrest frame 426, and the face mask 421 is fitted onto the sponge 422. The thickness of the sponge 422 is designed according to the massage depth requirements (e.g., 8-12cm), and a clearance hole 4221 is precisely opened at the position corresponding to the massage roller assembly 110. The diameter of the clearance hole 4221 is slightly larger than the maximum outer diameter of the massage roller assembly 110, so that the massage roller assembly 110 can be pushed out and retracted without jamming.

[0123] Each massage device corresponds to at least two fixed pressure plates 156, located above or below or on the left or right sides of the massage device, so that the massage device does not wobble after being mounted on the spring frame 425 by the fixed pressure plates 156. At the same time, when the spring frame 425 is slightly deformed by the pressure of the human body, the two massage modules 100 of the massage device can synchronously and adaptively adjust the included angle.

[0124] The vehicle seat 400 in this embodiment has a massage mode and a standby mode. See details below. Figures 13-14 , Figure 13 This is a cross-sectional view of the massage module in massage mode. When the user activates the massage mode, the airbag 133 is inflated, the spring 135 is compressed, the massage roller assembly 110 is pushed out, and the massage roller assembly 110 rotates to massage the back of the human body. Figure 14 This is a cross-sectional view of the massage module in standby mode. In standby mode, the airbag 133 deflates, and under the squeezing force of the spring 135, the massage roller assembly 110 retracts, and the massage roller assembly 110 stops massaging the human body.

[0125] In this embodiment, the air pump 303, airbag 133, first air pressure sensor 204, second air pressure sensor 205, first solenoid valve 207, second solenoid valve 208, and third solenoid valve 209 constitute a feedback system. This system measures the user's height, body shape, weight, and waist-back curve, providing precise, zoned, and intelligent massage. It solves the problem of poor adaptability and user experience of existing massager products for various body parts, including but not limited to limbs, waist, back, shoulders, neck, and head. The feedback system can also use the air pressure values ​​collected by the first and second air pressure sensors 204 and 205 to analyze the user's breathing frequency and intensity curves. Furthermore, it uses an intelligent program to analyze driver fatigue, abnormal physical conditions, etc., during driving. When these conditions occur, the feedback system causes the airbag 133 to generate high-frequency inflation and deflation vibrations, and can also link with a horn and alarm system to alert the user or trigger an alarm.

[0126] This embodiment can also implement the following multiple security measures:

[0127] (1) The upper limit of massage intensity is set with protection and warning values. When the warning value is exceeded, a warning is issued to remind the user. When the upper limit protection value is reached, the operation stops and the massage intensity is reduced to avoid damage to the massage area caused by excessive intensity.

[0128] (2) Set the safety threshold of the first air pressure sensor 204 and the second air pressure sensor 205. When the massage is performed while driving the vehicle, if a vehicle collision or other emergency occurs and the air pressure of the airbag 133 reaches the safety threshold, the second solenoid valve 208 and the third solenoid valve 209 can quickly release the gas in the airbag 133 and retract the massage roller assembly 110 to ensure the safety of the user's back.

[0129] (3) The airbag 133 is designed with a safe air pressure value. When the user is in massage mode, if an accidental collision occurs and the air pressure value of the airbag 133 reaches the damage air pressure value, the airbag 133 will self-destruct and release all the gas instantly on the side, thereby relieving the pressure and ensuring the user's safety.

[0130] Regarding the aforementioned safety measures (3), see [link to relevant documentation]. Figures 15-16 The airbag 133 has a cylindrical ring structure. The airbag 133 is formed by hot-pressing two pieces of cut thermoplastic elastomer material (TPE material) to form a pressed edge 1331. The self-destruct air pressure value can be set by adjusting the width of the pressed edge 1332. If the user is in massage mode and a vehicle collision or other emergency occurs, the pressed edge 1331 can instantly crack when the air pressure of the airbag 133 of the massage module 100 reaches the self-destruct air pressure value, thereby quickly deflating the air and shrinking the massage roller assembly 110 to ensure the safety of the user's back.

[0131] This application also discloses a massage device, which includes the massage device of any of the above embodiments.
