Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle parts technical field, especially a seat massage structure, and simultaneously, the utility model relates to a vehicle provided with the seat massage structure. BACKGROUND

[0002] With the improvement of people's living standards, people's requirements for the comfort of vehicle seats are also getting higher and higher, and modern car seats are evolving from basic support functions to intelligent interaction systems. The bionic adjusting device constructed based on the flexible pneumatic principle is being more and more widely applied in the comfort configuration of vehicle seats due to its characteristics of dynamically adapting to the human body curve. Among them, the massage structure seat driven by air pressure is widely used.

[0003] The current technical solution generally adopts a matrix layout of pneumatic unit network, and forms an air bag matrix composed of several air bags on the contact surface of the seat. Each independent air bag cooperates with the multi-channel electronic control unit through the air pump motor group, and can independently control the inflation and deflation of each air bag, so as to control the lifting height of each air bag, and realize local pressing effect through the set inflation and deflation sequence. Some models also introduce a pressure sensor feedback mechanism, which can automatically adjust the action strength and rhythm of the air bag array when detecting the change of the passenger posture, so that the massage track always matches the distribution of the human body center of gravity, and further improves the comfort.

[0004] However, this technology still has obvious physical limitations. The peak pressure output value of the pneumatic system is generally lower than that of the mechanical structure. Even if high-elasticity composite air bag materials are used, the maximum action pressure is still difficult to compare with conventional massage equipment. In addition, the mechanical energy generated by the air bag in the process of penetrating the foam layer is significantly attenuated, and there is a force unloading situation, which is not good for the massage effect of the user.

[0019] In addition, the clamping groove is arranged on the outer wall of the buffer ring and is distributed along the circumference of the buffer ring, so that the buffer ring can better disperse and absorb impact force when stressed, the buffer ring is clamped at the edge of the through hole through the clamping groove, so that quick and accurate installation can be realized, thereby saving installation time, and the close cooperation of the clamping groove and the through hole can ensure that the buffer ring is not easy to loosen or fall off during use, improve the reliability of the matching structure, and reduce maintenance costs. At the same time, after clamping, the buffer ring is in uniform contact with the edge of the through hole, so that the buffer force of the massage part in all directions is also relatively consistent, avoiding the problem of uneven buffering effect caused by unstable or position deviation of the buffer ring, and providing consistent comfortable massage experience for users.

[0020] Secondly, the convex ring arranged along the edge of the through hole and gradually increasing in outer diameter away from the mounting direction of the shell is arranged on the outside of the mounting shell, and one side wall of the clamping groove abuts on the convex ring, and the other side wall of the clamping groove abuts on the inner wall of the mounting shell. As above, while ensuring the reliability of the buffer ring, the contact area between the buffer ring and the mounting shell is increased, the buffering effect of the massage part is improved, thereby filtering the excess vibration generated by the massage part during operation, and improving the user experience. Moreover, compared with the ordinary flat mounting method, this design avoids the situation that the local stress is too large, effectively prolongs the service life of the buffer ring, and the buffering performance of the buffer ring in all directions is consistent. The limiting part is arranged to prevent the buffer ring from rotating, so that the massage part can drive the buffer ring to rotate during operation, thereby causing displacement of the buffer ring, leading to failure or causing additional noise, and affecting the user experience.

[0061] It should be noted that the embodiments in the utility model and the features in the embodiments can be combined with each other without conflict.

[0062] In the description of the utility model, it should be noted that the orientation words such as 'up, down, left, right, front, back' used in the embodiment are defined with the up-down direction, left-right direction and front-back direction of the seat as the reference. Among them, the up-down direction of the seat is also the height direction (Z direction) of the seat, the front-back direction of the seat is also the length direction (X direction) of the seat, and the left-right direction of the seat is also the width direction (Y direction) of the seat. In addition, the terms 'first' and'second' are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0063] Further, in the description of the present application, unless otherwise explicitly defined, the terms "mounting", "connecting", "connected", "connector" should be understood in a broad sense. For example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood in combination with the specific circumstances.

[0064] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0065] Embodiment one

[0066] The current technical solution generally adopts a matrix layout of pneumatic unit network, and forms an air bag matrix composed of a plurality of air bags on the contact surface of the seat. However, the technology still has obvious physical limitations, and the peak pressure output value of the pneumatic system is generally lower than that of the mechanical structure. Even if high-elasticity composite air bag material is used, the maximum acting pressure is still difficult to compare with conventional massage equipment, resulting in smaller massage force and poorer massage effect. In addition, the foam layer of the seat causes significant attenuation of the mechanical energy generated by the air bag in the process of penetrating the foam layer, and there is a force unloading situation, which is not good for the massage effect on the user.

[0067] Therefore, the present embodiment particularly provides a new seat massage structure which can improve the massage effect on the user. In the overall structure, the seat massage structure of the present embodiment comprises a mounting shell 2 arranged on a seat backrest 1, a driving part 22 arranged in the mounting shell 2, and a massage part 223 eccentrically arranged on a driving shaft 221 of the driving part 22. The mounting shell 2 is provided with a through hole 231 and a buffer ring 24 located in the through hole 231, and the massage part 223 is arranged in the buffer ring 24. The driving part 22 can drive the massage part 223 to extend and retract relative to the mounting shell 2, and the buffer ring 24 can apply a buffer force to the oscillation of the massage part 223 relative to the mounting shell 2.

[0068] The seat massage structure of the present embodiment can improve the massage force of the massage part 223 through the rigid mechanical transmission structure, and can achieve higher peak pressure output compared with the pneumatic system. The buffer ring 24 arranged to buffer the massage part 223 can absorb the vibration impact generated by the driving mechanism, effectively reduce the system working noise, and also help the massage part 223 to have a massage touch closer to the flexible pressing of the human hand, thereby improving the massage effect on the user. In addition, by arranging the mounting shell 2 and arranging the driving part 22 and the massage part 223 in the mounting shell 2, the seat massage structure can be modularly designed, which is beneficial to the installation and replacement of the seat massage structure on the seat.

[0069] Based on the above overview, an exemplary structural reference for the chair massage structure in this embodiment is provided. Figures 1 to 11 As shown, the mounting housing 2 includes a mounting plate 21 disposed on the seat back 1, and a housing body 23 fastened to the mounting plate 21. A drive unit 22 is disposed on the mounting plate 21, and a buffer ring 24 and a through hole 231 are disposed on the housing body 23. This configuration reduces the space occupied by the mounting housing 2 on the foam layer while providing reliable support for the drive unit 22, ensuring seating comfort. Simultaneously, placing the buffer ring 24 and through hole 231 on the housing body 23 facilitates the installation of the buffer ring 24 onto the drive unit 22 disposed on the mounting plate 21, and provides protection for the drive unit 22 after the housing body 23 is fastened to the mounting plate 21. Furthermore, the foam layer of the seat back 1 has a through hole for the massage unit 223 to pass through, allowing the massage unit 223 to pass through and directly contact the back of the human body. Compared to massage through a foam layer, this direct contact significantly reduces energy attenuation, allowing the mechanical energy of the massage unit 223 to be more effectively transmitted to the body's muscles. This enhances the massage intensity and effect, enabling the massage to penetrate deeper and more precisely onto acupoints and muscles, thus more effectively relieving muscle fatigue. The foam layer of the seat back 1 can be improved from the existing structure by simply providing a clearance space for the mounting housing 2 and a through-hole for the massage unit 223 to pass through.

[0070] Furthermore, in specific implementation, in detail, it is by Figures 1 to 3 as well as Figure 11 As shown, the mounting plate 21 in this embodiment is also provided with four positioning surfaces 211 for adapting to the steel wires 11 of the backrest frame. Each positioning surface 211 is welded to the steel wires 11 of the backrest frame. This arrangement ensures a high-strength and highly reliable rigid connection between the mounting plate 21 and the seat back 1, thereby providing a reliable mounting platform for the components mounted on the mounting plate 21. This avoids loosening of the mounting plate 21 and the steel wires 11 of the seat frame due to prolonged use, which could cause additional abnormal noises. It also avoids discomfort caused by the displacement of the equipment mounted on the mounting plate due to displacement of the mounting plate 21.

[0071] In addition, as another embodiment, in the present embodiment, a limiting portion is arranged between the buffer ring 24 and the mounting shell 2, and the limiting portion is used to limit the rotation of the buffer ring 24 relative to the mounting shell 2. As a preferred embodiment, the limiting portion of the present embodiment includes a positioning protrusion 235 arranged on the inner wall of the shell body 23, and a positioning hole 2421 arranged on the buffer ring 24. In order to improve the limiting effect, the positioning protrusion 235 is preferably arranged to be uniformly distributed along the circumference of the through hole 231, so as to better prevent the rotation of the buffer ring 24, thereby avoiding the rotation of the massage portion 223 during operation to drive the buffer ring 24 to rotate, and further causing the displacement of the buffer ring 24 to cause failure or additional noise, thereby affecting the user's experience.

[0072] Furthermore, as shown in Figure 8 and Figure 9 , the inner wall of the shell body 23 is further provided with a positioning baffle 233, and the positioning baffle 233 is provided with a positioning groove 22211 matched with the driving portion 22, which is used to further limit the driving portion 22 to avoid excessive vibration and affect the user's experience. Meanwhile, the inner wall of the shell body 23 is further provided with a positioning column 234 around the shell body 23, and the positioning column 234 is matched with the mounting plate 21 to fix and limit the shell body 23.

[0073] As shown in Figure 21 and Figure 22 , as a preferred embodiment, the outer wall of the buffer ring 24 is provided with a clamping groove 241 arranged along the circumference of the buffer ring 24, and the buffer ring 24 is clamped at the edge of the through hole 231 through the clamping groove 241. In this way, quick and accurate installation can be achieved, thereby saving installation time, and the tight fit of the clamping groove 241 and the through hole 231 can ensure that the buffer ring 24 is not easy to loosen or fall off during use, improve the reliability of the matching structure, and reduce maintenance costs.

[0074] Meanwhile, after clamping, the buffer ring 24 is in uniform contact with the edge of the through hole 231, so that the buffering force of the massage portion 223 in all directions is also relatively consistent, avoiding the problem of uneven buffering effect caused by unstable installation or position deviation of the buffer ring 24, and providing the user with consistent comfortable massage experience.

[0075] In addition, as shown in Figure 21 and Figure 22As shown, in specific implementation, in detail, the card slot 241 has a first slot wall 2411 arranged along the axial direction of the body of the buffer ring 24, and a second slot wall 2422 arranged obliquely relative to the first slot wall 2411, the first slot wall 2411 is arranged to face the inner wall of the mounting shell 2, and the second slot wall 2422 is located on the side of the first slot wall 2411 away from the mounting shell 2. In this way, the surface area of the card slot 241 can be increased, so that the card slot 241 is combined with the via hole 231 more firmly, and the reliability of the matching structure is improved.

[0076] Further, in detail, the buffer ring 24 further has a plurality of annular grooves 243 on the end face away from the mounting shell 2, and the annular grooves 243 are used to provide a deformation space to adapt to the movement of the massage part 223 penetrating the buffer ring 24, avoid aging and damage of the buffer ring 24 caused by stress, and improve the service life of the buffer ring 24.

[0077] In addition, it is worth mentioning that the outer wall of one end of the buffer ring 24 close to the first slot wall 2411 is further uniformly distributed with a plurality of protruding parts 242 around the buffer ring 24, and the positioning hole 2421 is arranged on the protruding part 242. The positioning hole 2421 is used to jointly form the limiting part with the positioning protrusion 235 on the mounting shell 2, so as to limit the buffer ring 24, avoid its rotation, and further prevent it from falling off and causing damage to the seat massage structure. The buffer ring 24 can be made of rubber material known to those skilled in the art, so as to absorb the vibration impact generated by the driving mechanism, help the massage touch of the massage part 223 to be closer to the flexible pressing of the human hand, optimize the massage feeling, and improve the user experience.

[0078] In this embodiment, as a preferred implementation form, as shown in Figure 4 and Figures 7 to 9 As shown, the mounting shell is provided with a via hole 231, and the outer side of the mounting shell 2 is provided with a convex ring 232, the convex ring 232 is arranged along the edge of the via hole 231, and the outer diameter of the convex ring 232 gradually increases in the direction away from the mounting shell 2, one side wall of the card slot 241 abuts against the convex ring 232, and the other side wall of the card slot 241 abuts against the inner wall of the mounting shell 2. As arranged above, while ensuring the reliable fixation of the buffer ring 24, the contact area between the buffer ring 24 and the mounting shell 2 is increased, the buffering effect on the massage part is improved, the excess vibration generated by the massage part during operation is filtered, and the user experience is improved. Moreover, compared with the ordinary flat mounting mode, this design avoids the case that the local stress is too large, effectively prolongs the service life of the buffer ring 24, and makes the buffering performance of the buffer ring 24 consistent in all directions.

[0079] In addition, in the specific implementation, in detail, the edge of the convex ring 232 should be chamfered or rounded. From the practical application point of view, if the edge of the convex ring is sharp, not only is it easy to scratch the surrounding parts during assembly, affecting the overall assembly accuracy and efficiency, but also during vehicle use, the sharp edge may gradually wear, deform, or even cause safety hazards due to various vibrations, friction, and other factors. After chamfering or rounding the edge of the convex ring 232, the above problems can be effectively avoided. On the one hand, during assembly, the smooth edge can make the operation more smooth, reducing the risk of part damage; on the other hand, during long-term use of the vehicle, the durability of the convex ring can be significantly improved, ensuring stable operation of the seat massage structure, thereby improving the overall performance and safety of the seat and even the vehicle.

[0080] As shown by Figure 4 and Figure 15 in the embodiment, as a preferred implementation form, the driving part 22 includes a driving motor provided on the mounting shell 2, a driving shaft 221 of the driving motor is provided with a transmission wheel 222, the transmission wheel 222 is provided with a mounting shaft 2221 biased on one side of the driving shaft 221, and the massage part 223 is rotatably provided on the mounting shaft 2221. The advantage of such arrangement is that it can make the structure of the transmission part more compact, accurately and efficiently transmit motion, simplify the number of parts, thereby reducing the production and maintenance cost of the product and improving the user experience. In the embodiment, the transmission wheel 222 is provided with a mounting shaft 2221 biased on one side of the driving shaft 221, so that an eccentric mechanism can be formed. When the driving shaft 221 rotates, the mounting shaft 2221 biased on one side of the driving shaft 221 will also rotate. Due to the eccentric design of the mounting shaft 2221 relative to the driving shaft 221, the mounting shaft 2221 on the outer edge of the transmission wheel 222 can convert the rotary motion into a periodic linear motion during rotation, thereby enabling the massage part 223 to realize reciprocating motion, so as to accurately control the motion direction and speed of the massage part 223, ensure the accuracy and consistency of the massage action, and efficiently transmit power while having a simple structure, which is beneficial to ensure the massage intensity and thereby ensure the user experience.

[0081] In addition, in the specific implementation, in detail, by Figures 24 to 25As shown, the massage unit 223 is connected to the mounting shaft 2221 via a bearing 2243. The outer wall of the mounting shaft 2221 on the transmission wheel 222 is provided with splines 22211, which connect to the bearing 2243 to prevent slippage and ensure a reliable connection. This further reduces friction, thereby reducing noise and heat generated by friction, extending the lifespan of the eccentric wheel mechanism, lowering maintenance costs, and improving the user experience. Simultaneously, the transmission wheel 222 is also provided with through holes 2222 for bolts to connect the transmission wheel 222 to the drive shaft 221.

[0082] Similarly, the transmission wheel 222 and the massage part 223 can also be directly rotatably connected. At this time, the outer wall of the mounting shaft 2221 on the transmission wheel 222 is provided with multiple grooves arranged along the axial direction of the mounting shaft 2221. This can reduce the contact area, thereby reducing the friction during rotation. At the same time, the groove design is also conducive to the storage of grease, which also helps to reduce friction, thereby reducing the noise and heat generated by friction, and ensuring the user's experience.

[0083] Furthermore, in this embodiment, by Figure 23 As shown, the drive shaft 221 of the drive motor has a transmission plane 2211 at the end away from the drive motor. This transmission plane 2211 is used to cooperate with the transmission wheel 222 to transmit torque. In this way, the processing process is simplified while ensuring reliable torque transmission, thereby reducing processing costs. At the same time, a fixing hole 2212 is also provided on it. The fixing hole 2212 cooperates with the transmission wheel 222 to limit the transmission wheel 222 from the drive shaft, improve the reliability of the equipment, and prevent the transmission wheel 222 from dislodging due to vibration caused by the vehicle, which would cause the transmission structure to fail and thus prevent the seat massage structure from failing or being damaged.

[0084] In addition, it is worth mentioning that in specific implementations, the drive unit 22 can be selected from a drive motor with a gearbox that is well known to those skilled in the art. By combining the drive motor with the gearbox, the output speed of the drive shaft 221 can be controlled, making the speed of the eccentric wheel adjustable. This allows for adjustment of the vibration intensity and frequency of the massage unit 223. At the same time, since the gearbox can amplify the torque, the massage unit 223 can have a wider range of intensity, thus helping to meet the needs of different users.

[0085] The massage part 223 comprises a support 224 rotatably arranged on the mounting shaft 2221, and massage hammers arranged on two opposite sides of the support 224, one end of each massage hammer is connected with the support 224, and the other end of each massage hammer is arranged in the buffer ring 24. In this way, a four-point massage scheme can be formed, so that a wider area of the back of the human body can be massaged at the same time. Compared with a single massage hammer, the comprehensiveness of massage can be effectively improved, and it is ensured that each part of the back can be fully relaxed and relaxed. Correspondingly, the through hole 231 on the mounting shell 2 and the buffer ring 24 of the embodiment are four arranged corresponding to the massage hammers.

[0086] At the same time, different massage angles and forces can be generated by rotating the mounting shaft 2221 in cooperation with the support body, so as to improve the user experience. Arranging the other end of the massage hammer in the buffer ring 24 can filter the slight vibration that may be generated by the massage hammer during operation, so that the massage process is more stable, which is beneficial to further improve the user experience. In addition, in specific implementation, in detail, the end of the massage hammer in contact with the user is made of rubber material to buffer the impact force, so that the massage hammer is closer to flexible massage during massage, avoiding the discomfort of the user caused by direct contact of the hard material with the body, thereby benefiting the protection of the user experience.

[0087] In the embodiment, as a preferred implementation form, Figure 2 and Figure 6 are shown, the support 224 comprises a support body and mounting arms 2241 arranged on two opposite sides of the support body, the support body is rotatably arranged on the mounting shaft 2221, and the support body extends to two opposite sides of the mounting shaft 2221, the mounting arms 2241 extend along the axial direction of the mounting shaft 2221 to the middle part of the driving motor, and the massage hammers are arranged on the mounting arms 2241. As arranged above, the arrangement of the massage hammers can be more compact, and the mounting structure can be more reliable, which is beneficial to reducing the volume and weight of the equipment while ensuring the structural strength, thereby avoiding the occupation of too much seat foam space to cause discomfort of the user, in addition, the rotation of the support body drives the massage hammers, so that the massage hammers can uniformly act on the massage area, avoiding discomfort caused by excessive or insufficient local massage force.

[0088] In specific implementation, in detail, as shown in Figure 5 and Figure 6 are shown, reinforcing ribs 2242 are further arranged between the mounting arms 2241 and the massage hammers, the reinforcing ribs 2242 are used to strengthen the connection between the massage hammers and the mounting arms 2241, avoiding deformation or breakage of the massage hammers during use due to resistance, thereby increasing the service life of the massage hammers, and also increasing the rigidity of the massage hammers to improve the massage effect.

[0089] In this embodiment, as a preferred implementation form, the drive shaft 221 extends to the two opposite sides of the driving part 22, and the massage part 223 is arranged at both ends of the drive shaft 221. The extension states of the massage parts 223 at both ends are opposite. In this way, the alternating massage effect can be realized, and the massage strength and rhythm on the left and right sides can be kept consistent, avoiding discomfort caused by excessive massage strength on one side or excessive stretching, thereby improving the user's experience.

[0090] In addition, in specific implementation, the wire harness connected with the driving part 22 can be arranged along the internal space of the mounting plate 21 and the shell body 23, and fixed by some wire slots or fixing clips to prevent the wire harness from shaking inside the seat and avoid friction or interference with other components. Then, the wire harness is arranged through the connection channel between the seat and the vehicle body. Generally, a special wire harness through hole can be arranged at the interface between the bottom or side of the seat and the vehicle body, and equipped with a rubber sealing sleeve and other components to prevent dust, water vapor and other substances from entering, while also playing a protective and fixing role for the wire harness. In addition, the wire harness can be arranged along the inner trim plate below the vehicle body or the vehicle frame, and integrated with other vehicle wire harnesses in the main wire harness slot, connected in parallel or branched with other electrical system wire harnesses of the vehicle body.

[0091] In addition, during use in rest or driving, the user adjusts the seat to a comfortable position, operates the HUT (Head-Up Display, head-up display) to enter the massage function opening interface, selects the massage mode according to the prompt of the HUT, and presses the start key. The vehicle-mounted computer outputs a control signal. At this time, the seat massage structure arranged on the seat backrest 1 is started, and the driving motor arranged on the mounting plate 21 drives the transmission wheel 222 arranged thereon through the output shaft. Then, the mounting shaft 2221 offset arranged on one side of the drive shaft 221 drives the bracket 224 arranged thereon to rotate, thereby indirectly driving the massage hammer to extend and retract, thereby realizing the vibration of the massage hammer. At this time, by adjusting the rotating speed of the driving motor, the massage hammer can realize the massage function of alternating knocking at different frequencies.

[0092] In addition, it is worth mentioning that the seat massage structure of the present embodiment can not only be adjusted through the HUT, but also can be adjusted through the key switch, voice and other start and adjustment mode operations commonly used by persons skilled in the art. Therefore, no longer will be described.

[0093] In this embodiment, the seat massage structure is installed by first aligning and welding the positioning surface of the mounting plate 21 with the steel wire 11 of the seat back 1 frame to form a reliable mounting base. Then, the drive motor is fixedly connected to the mounting plate 21, and a transmission wheel 222 is mounted on the drive shaft 221 of the drive motor. Fastening bolts are then inserted through the through hole 2222 on the transmission wheel 222 and the fixing hole 2212 on the drive shaft 221 to mate with the through hole 2222, thus fixing the transmission wheel 222 to the drive shaft 221 of the drive motor. Next, a massage hammer is rotatably inserted through the mounting shaft 2221 of the transmission wheel 222, or a bracket 224 is rotatably inserted through the mounting shaft 2221 of the transmission wheel.

[0094] Before installing the housing body 23, the buffer rings 24 need to be installed one by one into the through holes 231 on the housing body 23, ensuring that the slots 241 of the buffer rings 24 engage with the protruding rings 232 on the outside of the housing body 23, and that the positioning holes 2421 on the protruding portions 242 on the outer wall of the buffer rings 24 cooperate with the positioning protrusions 235 on the housing body 23 to ensure that the buffer rings 24 are fixed in place. When installing the housing body 23, the ends of each massage hammer away from the drive wheel 222 need to be inserted one by one into each buffer ring 24. Finally, the housing body 23 and the mounting plate 21 are fastened together and fixed to each other to complete the installation.

[0095] In this embodiment, the seat massage structure uses a drive unit 22 located within the mounting housing 2 to drive the massage unit 223 via an eccentric shaft. A buffer ring 24 is provided to cushion the massage unit 223. This rigid mechanical transmission structure enhances the massage intensity of the massage unit 223 while the buffer ring 24 absorbs vibrations and impacts generated by the drive mechanism, reducing system noise and making the massage feel of the massage unit 223 closer to the gentle pressure of a human hand, thereby improving the massage effect for the user. Furthermore, it should be noted that parts not mentioned in this embodiment, such as the foam layer material and the housing material, can be found in materials or structures well-known to those skilled in the art, and will not be described further.

[0096] Example 2

[0097] like Figures 12 to 20 As shown, this embodiment relates to an exemplary structure of a seat massage structure, the overall structure of which is the same as that of Embodiment 1, the difference being that the seat massage structure of this embodiment is composed of... Figures 12 to 20As shown, the massage unit 223 includes a massage hammer, one end of which is rotatably mounted on the mounting shaft 2221, and the other end of which passes through the buffer ring 24. This allows for a dual-point massage solution, and the rotation of the mounting shaft 2221 enables the massage hammer to produce different massage angles and intensities, facilitating various massage actions. Simultaneously, placing the other end of the massage hammer through the buffer ring 24 absorbs some impact force, making the massage process smoother and improving the user experience. Furthermore, this design occupies less space, reducing encroachment on the seat foam layer and preventing a foreign body sensation due to insufficient foam layer thickness, thus affecting the user experience. Correspondingly, in this embodiment, the through hole 231 and the buffer ring 24 on the mounting housing 2 are two corresponding to the massage hammer.

[0098] In addition, by Figure 15 as well as Figure 20 As shown, the mounting plate 21 in this embodiment is also provided with two positioning surfaces 211 for adapting to the steel wires 11 of the backrest frame. Each positioning surface 211 is welded to the steel wires 11 of the backrest frame. In this way, a high-strength and high-reliability rigid connection can be formed between the mounting plate 21 and the seat back 1, thereby providing a reliable mounting platform for the components installed on the mounting plate 21. This can prevent the mounting plate 21 from loosening with the steel wires 11 of the seat frame due to long-term use, thus avoiding additional abnormal noise. It can also prevent the discomfort caused by the displacement of the equipment installed on it due to the displacement of the mounting plate 21.
