Description

Technical Field

[0001] This application belongs to the field of massage device technology, and more specifically, relates to a massage module, massage assembly, and vehicle seat. Background Technology

[0002] In the field of massage devices such as car massage chairs and home massage chairs, to meet users' needs for relaxation and comfort, some existing technologies adopt a design approach that uses an intermediate medium to transmit power to achieve the massage function. When the power of such devices is transmitted from the drive source to the massage actuator, it needs to indirectly drive the massage actuator to act on the human body through changes in the physical state of the intermediate medium (such as changes in volume and pressure).

[0003] This indirect force transmission method inevitably involves power loss and delay due to the deformation and transformation of the medium, increasing the difficulty of precisely controlling the massage intensity. In practical applications, it is difficult to achieve fine-tuning based on individual user differences, often resulting in a mismatch between the intensity and the user's needs. Furthermore, the state of the medium is easily affected by factors such as the environment and usage time, further exacerbating the instability of intensity control and significantly limiting its ability to meet precise and personalized massage needs.

[0056] Please refer to the following: Figure 1 and Figure 2 The massage module 100 provided in this application embodiment will now be described. The massage module 100 includes: a drive mechanism 150 having a massage output shaft 1511; a massage roller assembly 110 being driven by the massage output shaft 1511, the massage output shaft 1511 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, and 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 1511; 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 1511.

[0057] Specifically, the drive mechanism 150 provides rotational power to the massage roller assembly 110, and the drive mechanism 150 includes a massage output shaft 1511. As a power transmission component, the massage output shaft 1511 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.

[0058] Optionally, 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 1511. The housing includes an upper motor housing 152 and a lower motor housing 153. The brushless motor 151 is located within the cavity formed by the upper and lower motor housings 152 and 153, while the massage output shaft 1511 is located outside the cavity formed by the upper and lower motor housings 152 and 153. In other embodiments, the drive mechanism 150 may further include a gearbox / gearbox / reduction gearbox (not shown in the figure) for increasing torque and reducing speed.

[0059] 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 1511. 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 1511. 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 1511.

[0060] 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 1511 and rotates around the axis of the massage output shaft 1511 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 1511 to adjust the contact depth with the human body and adapt to different massage intensity requirements.

[0061] For example, the operation of the massage module 100 in this embodiment is as follows:

[0062] 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 1511 until the massage rollers 111 apply pressure to the body. Simultaneously, the drive mechanism 150 activates, causing the massage output shaft 1511 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 1511.

[0063] In this embodiment, the massage output shaft 1511 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.

[0064] As an optional implementation, the massage output shaft 1511 passes through the through hole provided on the guide assembly and the through hole provided on the airbag 133; the guide assembly has an accommodating space for accommodating the airbag 133.

[0065] 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 1511. The massage output shaft 1511 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 1511.

[0066] 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 1511, making the expansion force of the airbag 133 act more concentrated and accurately on the massage roller assembly 110. Thus, the accommodating space expands or contracts along the axial direction of the massage output shaft 1511 under the drive of the airbag 133.

[0067] It should be noted that the airbag 133 does not contact the massage output shaft 1511 to avoid wear on the airbag 133 during the rotation of the massage output shaft 1511. There may be one or more airbags 133 in the accommodating space.

[0068] In this embodiment, the accommodating space enclosed by the guide component and the massage output shaft 1511 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, guide component and massage output shaft 1511 are integrated and installed in a limited space, reducing the space occupied by components and better adapting to modular installation requirements.

[0069] As an optional implementation, the guide 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 guide 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 1511 through the first guide structure; the massage output shaft 1511 passes through the through hole in the protective cover 131, the through hole in the support plate guide sleeve 132, and the through hole in the support plate 134, and is connected to the guide rod. One end of the guide rod 136 is connected, and the other end of the guide rod 136 is provided with a limiting block 1361; the massage roller assembly 110 is sleeved on the guide rod 136 and located between the limiting 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 1511 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 limiting 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.

[0070] 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 1511, 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 1511.

[0071] The support plate guide sleeve 132 extends axially along the massage output shaft 1511, and has a through-hole inside, serving as a passage for the massage output shaft 1511 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 1511, and a first slide rail 1322 extending along the axial direction of the massage output shaft 1511 is provided on the outer wall of the guide tube 1321.

[0072] 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 1511 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.

[0073] The first guide structure only allows the support plate 134 to translate along the axial direction of the massage output shaft 1511, 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 1511.

[0074] The end of the massage output shaft 1511 is fixedly connected to one end of the guide rod 136 (e.g., by screw locking, interference fit of 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 1511, thereby driving the massage roller assembly 110 to rotate. The other end of the guide rod 136 away from the massage output shaft 1511 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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 1511, while the guide rod 136 and the elastic element rotate with the massage output shaft 1511.

[0080] 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 1511.

[0081] As an optional implementation, 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.

[0082] 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.

[0083] 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 1511, the support plate 134 transmits thrust to the turntable 112 through the ball bearing 113. When the massage output shaft 1511 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.

[0084] 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 or roller sleeve 114, and is fixed to the turntable 112 by a roller fixing member 115. The roller fixing member 115 can be a nut or a retaining ring, which is fixed to the end of the rotating shaft 1121 by screws or retaining 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.

[0085] 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.

[0086] 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.

[0087] See Figure 3 This application provides a massage module, which includes at least one massage module 100 as described in the above embodiments.

[0088] As an optional implementation, the massage module further includes: a support member on which the massage module 100 is mounted; an air pump module 300 on which the support member is mounted; and a massage control module 200 on which the support member is mounted. The massage control module 200 is used to control the air pump module 300 to inflate or deflate the airbag 133 to drive the massage roller assembly 110 to push out or retract along the axial direction of the massage output shaft 1511, and to control the massage output shaft 1511 of the drive mechanism 150 to rotate.

[0089] It is easy to understand that, depending on the application scenario of the massage module, the support component can be set to a shape that adapts to the application scenario.

[0090] For example, the massage module can be applied inside the backrest 420 of a vehicle seat. Correspondingly, the support includes an upper backrest shell 423 and a lower backrest shell 424, which are mounted with screws to form a mounting cavity. The air pump module 300 and the massage control module 200 can be installed within the mounting cavity. The upper backrest shell 423 has multiple mounting slots for mounting the massage module 100. The massage module can also be applied inside the headrest 430 of a vehicle seat. Correspondingly, the support can be configured in a shape similar to the headrest 430; alternatively, the massage module can also be applied inside the seat cushion 410 of a vehicle seat. Correspondingly, the support can be configured as a plate, box, or mesh, etc.

[0091] Optionally, the air pump module 300 includes an air pump 303, an upper air pump housing 301, and a lower air pump housing 302, with the air pump 303 located within the cavity formed by the upper air pump housing 301 and the lower air pump housing 302.

[0092] The massage control module 200 can control the air path and the drive mechanism 150. Through air path control, it can independently control the inflation or deflation of the airbag 133. Through control of the drive mechanism 150, it can independently control the rotation of the massage output shaft 1511 of the drive mechanism 150.

[0093] The massage module in this embodiment is modularly installed. When a module fails, the faulty module can be directly disassembled and replaced with a new module without disassembling the entire massage module or seat, thus reducing maintenance time.

[0094] As an optional implementation, the massage control module 200 includes: a control component, an air passage 203, an air pressure sensor 206, a first solenoid valve 204, and at least one second solenoid valve 205; the air pump module 300 inflates the airbag 133 through the air passage 203, which includes a main pipe 2031 and at least one branch pipe 2032 connected to the main pipe 2031. Each branch pipe 2032 corresponds to one massage module 100, and the branch pipe 2032 is connected to the massage... The airbag 133 of module 100 is connected; the first solenoid valve 204 is installed on the main pipe 2031 to stabilize the air pressure in the main pipe 2031; the second solenoid valve 205 is installed on the branch pipe 2032 to allow the airflow in the branch pipe 2032 to pass through, be cut off, or be discharged; the detection end of the air pressure sensor 206 is connected to the branch pipe 2032; the control components are electrically connected to the air pump module 300, the air pressure sensor 206, the first solenoid valve 204, and at least one second solenoid valve 205 respectively.

[0095] Optionally, the control components include a PCB board 201 and a PCB protective shell 202. The PCB board 201 is fixed to the mounting cavity of the backplate housing 423 via the PCB protective shell 202. One or more control components can be disposed within the mounting cavity, and each control component can control one or more massage modules 100. For example, see [link to example]. Figure 3 There are three control components, which can be connected in series or in parallel. The air pipeline 203 includes three main pipelines 2031, each with a first solenoid valve 204. Each main pipeline 2031 is connected to two branch pipes 2032, which supply air to the airbags 133 of the two massage modules 100 respectively. Each branch pipe 2032 is equipped with a second solenoid valve 205. Thus, each control component can control two massage modules 100, and the three control components control a total of six massage modules 100.

[0096] Optionally, the number of massage modules 100, the number of branch pipes 2032, and the number of second solenoid valves 205 are the same.

[0097] Optionally, one air pump module 300 can be installed in the mounting cavity. It is easy to understand that multiple air pump modules 300 can also be installed in the mounting cavity. This embodiment does not limit this.

[0098] The detection end of the air pressure sensor 206 is connected to the branch pipe 2032 to collect the air pressure value within the branch pipe 2032. The air pressure sensor 206 can be integrated onto the PCB board 201 or electrically connected to the PCB board 201 via wires. The air pressure sensor 206 can transmit the collected air pressure signal to the control component, providing feedback for the air pressure adjustment of the airbag 133 of the massage module 100.

[0099] After receiving the real-time air pressure data from the air pressure sensor 206, the control component compares it with the preset target air pressure value (such as the air pressure value corresponding to the massage intensity set by the user):

[0100] When the air pressure in the branch pipe 2032 is lower than the target value, the control component controls the first solenoid valve 204 and the second solenoid valve 205 to remain open, and the air pump 303 inflates the air bag 133 until the air pressure sensor 206 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.

[0101] When it is necessary to reduce the massage intensity, the control component controls the second solenoid valve 205 to switch to the deflation state, and the gas in the airbag 133 is discharged through the branch pipe 2032. The air pressure sensor 206 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.

[0102] As an optional implementation, the massage module further includes: a ventilation bag 426, mounted on the support, and the ventilation bag 426 is provided with a clearance portion 4261 for avoiding the massage module 100; and an inflation device, mounted on the support, for inflating the ventilation bag 426.

[0103] Optionally, a ventilation bag 426 is provided on one side of the back cover 423 near the massage module 100. The clearance portion 4261 on the ventilation bag 426 can be a notch or a through hole, and the inflation device can be a blower 425.

[0104] When the massage module of this embodiment is installed inside the back panel of the vehicle seat, the blower 425 blows air into the ventilation bag 426. The air in the ventilation bag 426 is delivered to the seat sponge 422 and the lower back of the human body through the vents on the surface of the ventilation bag 426, thereby reducing the temperature of the part of the human body in contact with the seat. The avoidance part 4261 is designed to prevent the ventilation bag 426 from obstructing the push-out action and massage action of the massage module 100, so that the massage function and the ventilation function do not interfere with each other.

[0105] See Figures 4-5 This application embodiment 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 module 100 or massage assembly as described in any of the above embodiments.

[0106] It is easy to understand that the massage module 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.

[0107] Optional, see Figure 5 The backrest 420 includes a backrest frame 427, a sponge 422, a face mask 421, and a massage module. The sponge 422 has a clearance hole 4221 for the massage roller assembly 110 to extend or retract, and the end of the massage roller assembly 110 is located in the clearance hole 4221. The support of the massage module can be connected to the backrest frame 427 by screws. The sponge 422 is fixed to the backrest frame 427, and the face mask 421 is fitted onto the sponge 422.

[0108] The vehicle seat 400 in this embodiment has a massage mode and a standby mode. See details below. Figures 6-7 , Figure 6 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 7This 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.

[0109] In this embodiment, the air pump 303, airbag 133, air pressure sensor 206, first solenoid valve 204, and second solenoid valve 205 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 value collected by the air pressure sensor 206 to analyze the user's breathing frequency and intensity curves. Furthermore, it uses an intelligent program to analyze driver fatigue and other physical abnormalities. When these conditions occur, the feedback system causes the airbag 133 to generate high-frequency inflation and deflation vibrations, and can also trigger a horn and alarm system to alert the user or sound an alarm.

[0110] The vehicle seat 400 in this embodiment can also implement the following multiple safety measures:

[0111] (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.

[0112] (2) Set the safety threshold of the air pressure sensor 206. 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 205 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.

[0113] (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.

[0114] Regarding the aforementioned safety measures (3), see [link to relevant documentation]. Figures 8-9 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.
