[0021] The massage arm mechanism provided by the above technical solution includes a first massage arm, a second massage arm, a linkage mechanism, and a drive mechanism. The raising or retracting of the first and second massage arms can be achieved by directly driving one massage arm and indirectly driving the other massage arm through the linkage mechanism.

[0022] This approach significantly reduces the number of drive mechanisms required, eliminating the need for a separate drive unit for each massage arm.

[0023] Furthermore, the above method significantly improves the consistency of the movements of the first and second massage arms. In traditional dual-drive designs, if one of the two drives fails, it can easily lead to uncoordinated movements of the two massage arms, affecting the massage effect. However, this embodiment of the invention requires only one drive mechanism, fundamentally reducing the risk of inconsistent movements due to drive failure, ensuring that the two massage arms always move synchronously, and improving the performance of the massage arm mechanism.

It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0052] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment shall be considered part of the specification.

[0053] The dimensions of the various parts shown in the accompanying drawings are not drawn to actual scale. Common structural elements or elements of the same type are given the same reference numerals in the various drawings, and repeated descriptions of them are omitted where appropriate.

[0054] See Figures 1 to 3 This invention provides a massage arm mechanism, whose installation position inside a vehicle is as follows: Figure 1 As shown in N in the diagram. The massage arm mechanism is arranged in the back of the car seat, taking a retractable and concealed massage arm mechanism as an example. Figure 2 The diagram illustrates the massage arm mechanism hidden in the back of a car seat. Figure 3 The diagram illustrates the lifting of the massage arm mechanism.

[0055] When the massage function is not activated, the massage arm mechanism is concealed behind the seat back foam behind the seat back cover. When the massage function is activated, the first massage head 8 and the second massage head 9 of the massage arm mechanism move forward from the rear of the seat back foam. Ultimately, the first massage head 8 and the second massage head 9 protrude and push up the seat back cover, initiating a massage to the occupant's back. When the massage function is deactivated, the first massage arm 1 and the second massage arm 2 move in opposite directions, retracting and concealing themselves behind the seat back foam behind the seat back cover.

[0056] See Figures 1 to 5The massage arm mechanism includes a first massage arm 1, a second massage arm 2, a first massage head 8, a second massage head 9, a linkage mechanism 3, and a drive mechanism 4. The first massage head 8 is rotatably mounted on the first end of the first massage arm 1. The second massage head 9 is rotatably mounted on the first end of the second massage arm 2. The linkage mechanism 3 is connected to both the first massage arm 1 and the second massage arm 2. The drive mechanism 4 is driven by one of the first massage arm 1 or the second massage arm 2, so that the first massage arm 1 and the second massage arm 2 move closer or further apart synchronously via the linkage mechanism 3.

[0057] The first massage arm 1 and the second massage arm 2 can be made of lightweight yet high-strength metal materials, such as aluminum alloy or magnesium alloy, which are lightweight and high-strength, ensuring structural strength while reducing overall weight. Alternatively, they can be made of steel, which facilitates rapid movement of the massage arms and reduces additional strain on the seat structure. Their shape is designed to conform to the curve of the human back, allowing them to better fit the occupant's back when raised, improving massage comfort. For example, in the upper middle area of ​​the seat back, the massage head's trajectory matches the curve of the human back, enhancing the massage effect.

[0058] The first massage head 8 and the second massage head 9 can be made of elastic silicone material to form round rollers with a smooth surface or irregular bumps. This bumpy structure can reduce noise during massage by rolling, and can also use the bumps to precisely stimulate acupoints, such as acupoints on the back, to promote blood circulation and relieve muscle fatigue.

[0059] The linkage mechanism 3 is used to realize the linkage between the first massage arm 1 and the second massage arm 2. There are various ways to achieve this, such as linkage mechanism, gear mechanism, etc.

[0060] The drive mechanism 4, for example, uses a DC motor, which features fast response and high control precision. Through precise control algorithms, the movement speed and intensity of the massage arm can be accurately controlled according to different massage modes. For example, in a soothing and relaxing massage mode, the motor drives the massage arm to move at a slower speed and with lighter intensity; in a deep muscle massage mode, the motor drives the massage arm to move at a faster speed and with greater intensity.

[0061] During use, activating the massage function causes the power source 41 of the drive mechanism 4 to drive the linkage mechanism 3, which in turn raises the first massage arm 1 and the second massage arm 2 to a set height simultaneously, providing a massage function for the passenger's back. Because the movement trajectory of the massage head conforms to the curve of the human back and the massage head is reasonably designed, it can provide a comprehensive and comfortable massage for the passenger's back, effectively relieving back muscle tension and reducing fatigue during travel. Simultaneously, the rotation of the massage head and the synchronized movement of the massage arms simulate various techniques of manual massage, such as kneading, pinching, pushing, and pressing, enhancing the massage experience.

[0062] When the massage function is turned off, the power source 41 of the drive mechanism 4 drives the first massage arm 1 and the second massage arm 2 to move in opposite directions, so that the first massage arm 1 and the second massage arm 2 are retracted to a safe area away from the occupant's body and hidden away.

[0063] The first massage arm 1 and the second massage arm 2 adopt the above structure, which has many advantages: Firstly, when the massage function is not activated, if the massage head continuously protrudes and presses against the foam and back cover, passengers will feel discomfort from the hard lumps and the rollers digging into their backs. The above-mentioned technical solution, when the massage function is not needed, allows the first massage arm 1 and the second massage arm 2 to retract into the inner side of the backrest frame plane or into the foam groove, restoring the backrest surface to a smooth and soft state, eliminating any foreign body sensation and providing a better riding experience.

[0064] Secondly, during vehicle bumps and rapid acceleration / deceleration, if the massage arms are constantly extended, the exposed arms are prone to impacting the guide rail ends, gears, and foam components due to inertial impact, causing abnormal noises and accelerating component fatigue wear. In the event of a frontal or rear-end collision, the extended rigid massage arms may also impact the spine of the occupants, causing secondary injuries. Retracting the massage arms can significantly reduce these safety risks.

[0065] Finally, after the massage function stops, if the vehicle is traveling on a bumpy road and the massage noses are not retracted, tiny gaps can easily form between the exposed massage arms and the foam, cover, and frame, potentially causing abnormal noises while the vehicle is in motion. Retracting the first massage arm 1 and the second massage arm 2 can also reduce seat noise issues when not in use.

[0066] See also Figures 1 to 9 In the first embodiment, the second end of the first massage arm 1 is rotatably connected to the second end of the second massage arm 2. The linkage mechanism 3 includes a core 310, a first connecting part 311, and a second connecting part 312. The first end of the first connecting part 311 is rotatably connected to the core 310; the second end of the first connecting part 311 is integrally or fixedly connected to the first massage arm 1. The first end of the second connecting part 312 is rotatably connected to the core 310, and the second end of the second connecting part 312 is hinged to the connection point of the second massage arm 2.

[0067] The second end of the first massage arm 1 and the second end of the second massage arm 2 can be rotatably connected. Specifically, the rotatable connection between the two can be achieved through a pin or the like, so that the first massage arm 1 and the second massage arm 2 can rotate relative to each other, providing conditions for subsequent linkage between the two.

[0068] After the mechanism 310 is installed onto the seat back, it can slide up and down relative to the seat back. The mechanism 310 serves as the mounting base for other components. The first end of the first connecting part 311 is rotatably connected to the mechanism 310, and the rotatable connecting shaft is marked C1. The first connecting part 311 can be understood as the protrusion of the first massage arm 1, see [reference needed]. Figure 5 This allows the first connecting part 311 to rotate normally as the first massage arm 1 moves.

[0069] When the mechanism 310 drives the first connecting part 311 to rotate, the first connecting part 311 can drive the first massage arm 1 to move with a more effective lever arm relationship, and drive the second massage arm 2 to rotate through the first massage arm 1, so that the first massage arm 1 and the second massage arm 2 can both move according to a specific trajectory and manner.

[0070] See also Figures 1 to 5 The drive mechanism 4 includes a power source 41, a slider 42, and a push rod 43. The power source 41 is configured to provide power; the slider 42 is driven by the power source 41 to move linearly under the drive of the power source 41; the first end of the push rod 43 is rotatably connected to the slider 42. The second end of the push rod 43 is rotatably connected to the first massage arm 1; or, the second end of the push rod 43 is rotatably connected to the second massage arm 2.

[0071] If the object driven by the power source 41 is the first massage arm 1, then the position of the push rod 43 is as follows: Figure 5 The situation is illustrated. If the object driven by the power source 41 is the second massage arm 2, then the position of the push rod 43 is as described later. Figure 10 The second type of embodiment illustrates the situation.

[0072] The function of the power source 41 is to provide power for the movement of the first massage arm 1 and the second massage arm 2, such as for electric drive components, compressed gas drive components, etc.

[0073] The slider 42 is driven by the power source 41, and moves linearly under the drive of the power source 41. For example, if the power source 41 is a linear motor, the motor drives the slider 42 to reciprocate along a specific linear track through a speed regulating component such as a gearbox. Of course, the motor can also be a rotary motor, which converts rotational power into linear power through a lead screw slider mechanism or a gear rack mechanism, thereby driving the slider 42 to move.

[0074] See also Figure 5The push rod 43 includes a bearing end and a ball joint section, which are connected by a pin or similar connecting component. The bearing end, serving as the first end of the push rod 43, is used to mount the slider 42. The ball joint section, serving as the second end of the push rod 43, is used to connect to the driven massage arm: if the driven object is the first massage arm 1, the push rod 43 is ball joint connected to the first massage arm 1; if the driven object is the second massage arm 2, the push rod 43 is ball joint connected to the second massage arm 2.

[0075] See Figure 5 and Figure 9 When it is necessary to lift the first massage arm 1 and the second massage arm 2, the entire power transmission process is as follows, taking the drive source driving the first massage arm 1 as an example: the power source 41 starts to drive the slider 42 to make linear motion, and the direction of movement is as follows: Figure 5 As shown in S1, the slider 42 drives the connected push rod 43. Since the two ends of the push rod 43 are rotatably connected to the first massage arm 1 and the slider 42 respectively, the push rod 43, driven by the slider 42, will push the first massage arm 1 to rotate clockwise. The connection between the push rod 43 and the slider 42 can be achieved by an eccentric shaft as described later, so as to realize a wider range of functions for the massage arm mechanism. It should be noted that the above-described eccentric shaft solution is applicable to all embodiments described herein.

[0076] Since the second ends of the first massage arm 1 and the second ends of the second massage arm 2 are rotatably connected, the second end of the second massage arm 2 will also change position after the second end of the first massage arm 1 changes position. Because the second massage arm 2 is rotatably connected to the mechanism 310 via the second connecting part 312, the second end of the second massage arm 2 faces... Figure 5 When the movement is shown to the lower left, the entire second massage arm 2, constrained by the second connecting part 312, will rotate counterclockwise. This achieves the opposite movement of the first massage arm 1 and the second massage arm 2, thus achieving the lifting of the first massage arm 1 and the second massage arm 2. The entire process is as follows: Figure 9 The process is shown by the solid arrow in the image.

[0077] See Figure 5 and Figure 9 When it is necessary to lower the first massage arm 1 and the second massage arm 2, the entire power transmission process is the reverse of the movement process described above. Taking the drive source driving the first massage arm 1 as an example: the power source 41 starts to drive the slider 42 to make linear motion, and the direction of movement is as follows: Figure 5As shown in S2, the slider 42 drives the connected push rod 43. Since the two ends of the push rod 43 are rotatably connected to the first massage arm 1 and the slider 42 respectively, the push rod 43, driven by the slider 42, will push the first massage arm 1 to rotate counterclockwise. Since the second end of the first massage arm 1 and the second end of the second massage arm 2 are rotatably connected, after the second end of the first massage arm 1 changes position, the second end of the second massage arm 2 will also change position accordingly. Since the second massage arm 2 is rotatably connected to the mechanism 310 through the second connecting part 312, the second end of the second massage arm 2 faces... Figure 5 When the upper right movement is shown, the entire second massage arm 2, constrained by the second connecting part 312, will rotate clockwise. This achieves the opposite movement of the first massage arm 1 and the second massage arm 2, thus realizing the lowering, i.e., resetting, of the first massage arm 1 and the second massage arm 2. The entire process is as follows: Figure 9 The process is indicated by the dashed arrow in the image.

[0078] See Figure 10 and Figure 11 In the second embodiment, the linkage mechanism 3 is driven to connect with the second massage arm 2. Specifically, the second end of the push rod 43 is rotatably connected to the second massage arm 2; the second end of the push rod 43 is located between the first end of the second massage arm 2 and the first connection point B1 of the second massage arm 2.

[0079] This method is similar to the technical solution of the first embodiment described above, except that the power source 41 drives the second massage arm 2, and the power is transmitted to the first massage arm 1 via the slider 42 and the second massage arm 2. The first massage arm 1 and the second massage arm 2 still need to achieve opposite and back-to-back movements. The entire movement process is also similar to the process described above, and will not be repeated here.

[0080] See Figures 5 to 11 In the two embodiments described above, the massage arm mechanism further includes a first kneading shaft 5. The first kneading shaft 5 can be located at the indirect connection between the first massage arm 1 and the mechanism 310, or it can be located at the indirect connection between the second massage arm 2 and the mechanism 310. The former approach will be described here. The first end of the first connecting part 311 is connected to the mechanism 310 via the first kneading shaft 5. A fisheye bearing D or a similar kinematic pair is provided between the first kneading shaft 5 and the mechanism 310. The fisheye bearing and similar kinematic pairs used herein can achieve the following effects: the fisheye bearing can achieve a small range of omnidirectional deflection, offsetting the misalignment caused by assembly errors and motion deformation, and reducing motion jamming. Furthermore, the fisheye bearing can evenly distribute the lateral pulling and squeezing forces transmitted from the corresponding massage arm to the mechanism 310, reducing single-point wear of the kneading shaft. The fisheye bearing has a certain floating compensation characteristic, reducing the alignment requirements during assembly and increasing assembly efficiency.

[0081] The first kneading shaft 5, for example, can be a bent shaft, cylindrical in shape, and made of wear-resistant metals such as stainless steel or aluminum alloy. The two ends of the first kneading shaft 5 are respectively adapted to the first end of the first connecting part 311 and the corresponding connecting part of the movement 310.

[0082] Driven by an external force, the first kneading shaft 5 can rotate and oscillate to a certain extent at its connecting part. This allows for more flexible transmission of power from the mechanism 310 to the first connecting part 311, which in turn drives the first massage arm 1, and via the first massage arm 1, the second massage arm 2, to oscillate slightly. When the first connecting part 311 drives the first massage arm 1, the first kneading shaft 5 simultaneously rotates and oscillates slightly, simulating manual kneading motions to enhance the massage effect on the occupant's back, thus enabling the massage arm mechanism to achieve a wider range of massage functions.

[0083] See Figure 12 and Figure 13 In the third embodiment, the linkage mechanism 3 includes a core 310 and a first base 321. The first base 321 is mounted on the core 310; the second end of the first massage arm 1 is rotatably connected to the first base 321, and the second end of the second massage arm 2 is rotatably connected to the first base 321; the second end of the first massage arm 1 engages with the second end of the second massage arm 2.

[0084] The first base 321 is mounted on the mechanism 310. The first base 321 limits the movement of the first massage arm 1 and the second massage arm 2, so that the movement of the first massage arm 1 and the second massage arm 2 is within a set range.

[0085] In some embodiments, the massage arm mechanism further includes a second kneading shaft 6, and the first base 321 is mounted to the mechanism 310 via the second kneading shaft 6. Each kneading shaft described herein can be a bent shaft as described later, and the second kneading shaft 6 can also be a bent shaft. After the first base 321 is mounted via the second kneading shaft 6, the first base 321 is positioned relative to the mechanism 310 in... Figure 12 The direction perpendicular to the paper plane shown has a certain degree of freedom for linear motion.

[0086] The second end of the first massage arm 1 is rotatably connected to the first base 321, for example, by means of a pin, so that the first massage arm 1 can rotate flexibly relative to the first base 321. Similarly, the second end of the second massage arm 2 is also rotatably connected to the first base 321 in a similar manner.

[0087] Furthermore, the second end of the first massage arm 1 engages with the second end of the second massage arm 2. A toothed structure can be provided at the second end of both the first massage arm 1 and the second massage arm 2 to achieve engagement. The engaging structure ensures the synchronization of their rotational movements through the interlocking of the teeth.

[0088] See also Figure 12 and Figure 13 The drive mechanism 4 includes a power source 41, a slider 42, and a push rod 43. The power source 41 is configured to provide power. The slider 42 is driven by the power source 41 to move linearly under its influence. The second end of the push rod 43 is rotatably connected to the third connection point A3 of the first massage arm 1. The third connection point of the first massage arm 1 is located between the first end and the second end of the first massage arm 1, meaning the power source 41 drives the first massage arm 1. Figure 12 and Figure 13 The situation is as shown. Alternatively, the second end of the push rod 43 is rotatably connected to the third connection point of the second massage arm 2, and the third connection point of the second massage arm 2 is located between the first end and the second end of the second massage arm 2, that is, the power source 41 drives the second massage arm 2. The following description takes the drive mechanism 4 driving the first massage arm 1 through the push rod 43 as an example.

[0089] The power source 41 provides the power required for the rotation of the first massage arm 1 and the second massage arm 2, such as an electric drive component or a compressed gas drive component. The first end of the push rod 43 is directly connected to the power source 41. After the power source 41 is started, the push rod 43 will move linearly under the drive of the power source 41.

[0090] There are two drive connection methods. One method involves a rotatable connection between the second end of the push rod 43 and the third connection point of the first massage arm 1. This third connection point is located between the first and second ends of the first massage arm 1. The power source 41 drives the first massage arm 1 through this connection method. In this case... Figure 12 and Figure 13 The diagram is shown in the image. Another configuration is where the second end of the push rod 43 is rotatably connected to the third connection point of the second massage arm 2, and this third connection point is located between the first and second ends of the second massage arm 2, i.e., the power source 41 drives the second massage arm 2. This configuration is not shown in the image.

[0091] The following description uses the example of the drive mechanism 4 driving the first massage arm 1 via the push rod 43 to illustrate the action process. When the power source 41 is activated, the output power drives the push rod 43 to move linearly. Since the second end of the push rod 43 is rotatably connected to the third connection point of the first massage arm 1, the linear motion of the push rod 43 is converted into a pushing force on the first massage arm 1, causing the first massage arm 1 to rotate around its rotational connection point A4 with the first base 321. Furthermore, because the second end of the first massage arm 1 meshes with the second end of the second massage arm 2, the rotation of the first massage arm 1 is transmitted to the second massage arm 2 through the meshing relationship, thereby driving the second massage arm 2 to rotate synchronously around point B4, where point B4 is the rotational connection point between the second massage arm 2 and the first base 321, thus realizing the adjustment of the angle between the first massage arm 1 and the second massage arm 2.

[0092] When it is necessary to lift the first massage arm 1 and the second massage arm 2, the slider 42 moves along the S1 direction. See below for the entire process. Figure 13 The process is illustrated by the solid arrow. When it is necessary to lift the first massage arm 1 and the second massage arm 2, the slider 42 moves along the S2 direction. See [link to full process] for details. Figure 13 The process is indicated by the dashed arrow.

[0093] See Figure 14 and Figure 15 In the fourth embodiment, the linkage mechanism 3 includes a core 310 and a second base 331. The second base 331 is linearly movable and mounted on the core 310; the fourth connection point A41 of the first massage arm 1 is rotatably connected to the second base 331, and the fourth connection point B41 of the second massage arm 2 is rotatably connected to the second base 331.

[0094] In this configuration, the second end of the first massage arm 1 is provided with a first sliding groove, and the second end of the second massage arm 2 is slidably mounted in the first sliding groove. The drive mechanism 4 is drivenly connected to the second massage arm 2. Alternatively, the second end of the second massage arm 2 is provided with a second sliding groove 21, and the second end of the first massage arm 1 is slidably mounted in the second sliding groove 21. The drive mechanism 4 is drivenly connected to the first massage arm 1. Figure 14 and Figure 15 This illustration shows the method. The first and second slides 21 can be straight or curved.

[0095] After the movement 310 is installed, its position is fixed, and the movement 310 provides the mounting base for the linkage mechanism 3. The second base 331 is linearly movable and mounted on the movement 310. For example, the movement 310 is provided with a linear guide rail, and the second base 331 cooperates with the guide rail through the slider 42 to achieve linear movement along the movement 310. The second base 331 may be a V-shaped bracket.

[0096] The fourth connection point A41 of the first massage arm 1 is rotatably connected to the second base 331. Similarly, the fourth connection point B41 of the second massage arm 2 is also rotatably connected to the second base 331, so that the two massage arms can rotate flexibly relative to the second base 331.

[0097] The drive mechanism 4 has two connection methods: In the first method, a first sliding groove is provided on the first massage arm 1. Specifically, the second end of the first massage arm 1 is provided with the first sliding groove, and the extension direction of the first sliding groove forms an obtuse angle with the length direction of the first massage arm 1. The second end of the second massage arm 2 is provided with a sliding component, so that the second end of the second massage arm 2 can be slidably installed within the first sliding groove. At this time, the drive mechanism 4 is drivenly connected to the second massage arm 2. When the drive mechanism 4 is activated, it drives the second massage arm 2 to move. The second massage arm 2 slides within the first sliding groove. At the same time, since both the first massage arm 1 and the second massage arm 2 are rotatably connected to the second base 331, the movement of the second massage arm 2 is transmitted to the first massage arm 1 through the first sliding groove, causing the first massage arm 1 to rotate, thereby realizing the coordinated action of the two massage arms.

[0098] In the second configuration, a second groove 21 is provided at the second end of the second massage arm 2, and a sliding component can be provided at the second end of the first massage arm 1, so that the second end of the first massage arm 1 can be slidably mounted in the second groove 21. The drive mechanism 4 is drivenly connected to the first massage arm 1. When the drive mechanism 4 drives the first massage arm 1 to move, the first massage arm 1 slides in the second groove 21, and at the same time, the power is transmitted to the second massage arm 2 through the second base 331, so that the second massage arm 2 rotates around its connection point with the second base 331, achieving synchronous movement of the two massage arms.

[0099] exist Figure 14 and Figure 15 In the illustrated scenario, the slider 42 of the drive mechanism 4 moves along the S1 direction, raising the first massage arm 1 and the second massage arm 2; the slider 42 of the drive mechanism 4 moves along the S2 direction, lowering the first massage arm 1 and the second massage arm 2.

[0100] In some embodiments, the massage arm mechanism further includes a third kneading shaft 7, and the second base 331 is connected to the mechanism 310 via the third kneading shaft 7.

[0101] The second base 331 is connected to the movement 310 via the third kneading shaft 7. The third kneading shaft 7 can be a bent shaft, and the material can be a metal material, such as high-quality alloy steel or aluminum alloy.

[0102] Under external force, the third kneading shaft 7 will rotate and oscillate slightly. On the one hand, it can more flexibly transmit the power of the movement 310 to the second base 331, making the linear movement of the second base 331 reliable and smooth. On the other hand, the rotation and oscillation of the third kneading shaft 7 will be transmitted to the first massage arm 1 and the second massage arm 2, thereby simulating the action of manual kneading, enhancing the massage effect on the occupant's body, and further enriching the massage function of the massage arm mechanism.

[0103] See Figure 16 and Figure 17In the fifth embodiment, the linkage mechanism 3 includes a core 310, a third base 341, and a third connecting part 342. The third base 341 is linearly movably mounted on the core 310; the second end of the first massage arm 1 is rotatably connected to the third base 341, and the second end of the second massage arm 2 is rotatably connected to the third base 341. The third connecting part 342 connects the second end of the first massage arm 1 to the second end of the second massage arm 2.

[0104] The movement 310 provides a mounting and support base for the linkage mechanism 3. The third base 341 is linearly movable on the movement 310, for example, by setting a linear guide rail on the movement 310, and the bottom of the third base 341 is equipped with a sliding component adapted to it, so that the third base 341 can move linearly along the guide rail on the movement 310.

[0105] The second end of the first massage arm 1 is rotatably connected to the third base 341 via a pin or other connecting component, allowing the first massage arm 1 to rotate flexibly relative to the third base 341. Similarly, the second end of the second massage arm 2 is rotatably connected to the third base 341 in a similar manner.

[0106] The second end of the first massage arm 1 extends outward, and the angle between the extended portion and the main body is an obtuse angle. The second end of the second massage arm 2 also extends outward, and the angle between the extended portion and its main body is also an obtuse angle.

[0107] The third connecting part 342 serves to connect the second ends of the first massage arm 1 and the second massage arm 2. Specifically, it rotatably connects the extension of the second end of the first massage arm 1 with the extension of the second end of the second massage arm 2 to achieve linkage between the two.

[0108] The drive mechanism 4 is implemented in the same way as the above embodiment, and also includes a power source 41, a slider 42, and a push rod 43. The push rod 43 is drivenly connected to one of the first massage arm 1 and the second massage arm 2. Figure 16 and Figure 17 The diagram illustrates the drive connection with the first massage arm 1.

[0109] When the slider 42 of the drive mechanism 4 moves in direction S1, it pushes up the first massage arm 1. Since the first massage arm 1 and the second massage arm 2 are connected by the third connecting part 342, the rotation of the first massage arm 1 will be transmitted to the second massage arm 2, so that the second massage arm 2 will also be lifted.

[0110] Conversely, when the slider 42 of the drive mechanism 4 moves along direction S2, the first massage arm 1 will be lowered. Since the first massage arm 1 and the second massage arm 2 are connected by the third connecting part 342, the rotation of the first massage arm 1 will be transmitted to the second massage arm 2, thereby causing the second massage arm 2 to also be lowered.

[0111] The above technical solution allows the first massage arm 1 and the second massage arm 2 to move in tandem due to the connection of the third connecting part 342, thereby changing the angle between them and meeting different action requirements during the massage process, providing users with a diverse massage experience.

[0112] In some embodiments, the massage arm mechanism further includes a fourth kneading shaft 10, and the first end of the first massage arm 1 is connected to the third base 341 via the fourth kneading shaft 10.

[0113] The fourth kneading shaft 10 can be a bent shaft, and the material can be metal, such as high-quality alloy steel or aluminum alloy.

[0114] Under external force, the fourth kneading shaft 10 will rotate and oscillate slightly. On the one hand, it can more flexibly transmit the power of the movement 310 to the third base 341, making the linear movement of the third base 341 reliable and smooth. On the other hand, the rotation and oscillation of the fourth kneading shaft 10 will be transmitted to the first massage arm 1 and the second massage arm 2, thereby simulating the action of manual kneading, enhancing the massage effect on the occupant's body, and further enriching the massage function of the massage arm mechanism.

[0115] See Figure 18 and Figure 19 In the sixth embodiment, the linkage mechanism 3 includes a core 310 and a spherical fulcrum 351. The second massage arm 2 is rotatably mounted on the core 310; the spherical fulcrum 351 is mounted on the core 310; the first massage arm 1 is provided with a first movable groove 12, and the spherical fulcrum 351 is located in the first movable groove 12. The first movable groove 12 can be a straight groove or an arc-shaped groove. The second end of the second massage arm 2 is constructed in a Y-shape; the second end of the first massage arm 1 is rotatably connected to one end of the second end of the second massage arm 2, and the drive mechanism 4 is drivenly connected to the other end of the second end of the second massage arm 2.

[0116] The drive mechanism 4 can still adopt the structure described above. The drive mechanism 4 includes a power source 41, a slider 42, and a push rod 43. The push rod 43 is rotatably connected to one of the Y-forks at the second end of the second massage arm 2.

[0117] When the drive mechanism 4 is activated, causing the Y-shaped end of the second massage arm 2 to move, the second massage arm 2 rotates around its rotation point B6 with the mechanism 310. Since the first massage arm 1 engages with the spherical fulcrum 351 through the movable groove, and its second end is rotatably connected to the second massage arm 2, the movement of the second massage arm 2 can be transmitted to the first massage arm 1, causing the first massage arm 1 to move along the engagement trajectory of the movable groove and the spherical fulcrum 351, that is, the first massage arm 1 also rotates, thereby realizing the coordinated action of the first massage arm 1 and the second massage arm 2, changing the angle between them to meet different massage needs.

[0118] like Figure 18 and Figure 19 As shown, when the slider 42 of the drive mechanism 4 moves along direction S1, it pushes up the second massage arm 2. Since the first massage arm 1 and the second massage arm 2 are connected, the rotation of the second massage arm 2 will be transmitted to the first massage arm 1, thereby causing the first massage arm 1 to also be lifted.

[0119] Conversely, when the slider 42 of the drive mechanism 4 moves along direction S2, the second massage arm 2 will be lowered. Since the first massage arm 1 and the second massage arm 2 are connected, the rotation of the second massage arm 2 will be transmitted to the first massage arm 1, thereby causing the first massage arm 1 to also be lowered.

[0120] Understandably, a second movable groove can also be provided on the second massage arm 2. In this case, the linkage mechanism 3 includes a core 310 and a spherical fulcrum 351. The first massage arm 1 is rotatably mounted on the core 310. The spherical fulcrum 351 is mounted on the core 310; the second massage arm 2 is provided with a second movable groove, and the spherical fulcrum 351 is located in the second movable groove. The second movable groove can be a straight groove or an arc-shaped groove. The second end of the first massage arm 1 is constructed in a Y-shape; the second end of the second massage arm 2 is rotatably connected to one end of the second end of the first massage arm 1, and the drive mechanism 4 is drivenly connected to the other end of the second end of the first massage arm 1.

[0121] In some embodiments, the massage arm mechanism further includes a fifth kneading shaft 13; the second end of the second massage arm 2 is configured in a Y-shape and is connected to the mechanism 310 via the fifth kneading shaft 13; or, the second end of the first massage arm 1 is configured in a Y-shape and is connected to the mechanism 310 via the fifth kneading shaft 13. Each kneading shaft described below can be a bent shaft to achieve the kneading function.

[0122] In all the above embodiments, the push rod 43 can adopt the structure described in the first embodiment.

[0123] The movement principle of this method is similar to that described above, where the first movable groove 12 is set in the first massage arm 1, and will not be repeated here.

[0124] See Figures 20 to 23 The seventh embodiment is described below. The linkage mechanism 3 includes a rotating joint, with the middle regions of the first massage arm 1 and the second massage arm 2 hinged together via the linkage mechanism 3. The second end of the first massage arm 1 is rotatably connected to the mechanism 310, and the second end of the second massage arm 2 is drivenly connected to the drive mechanism 4. The slider 42 of the drive mechanism 4 moves linearly, causing the second massage arm 2 to lift and lower. During this process, the second massage arm 2 simultaneously lifts and lowers the first massage arm 1, which is hinged to it.

[0125] The first massage arm 1 and the second massage arm 2 intersect to form a scissor structure. A hinged kinematic pair is provided at their intersection, which serves as the linkage mechanism 3. In this embodiment, the slider 42 is installed with the second massage arm 2 in the following manner, see [reference needed]. Figure 20 and Figure 21 The second end of the second massage arm 2 is connected to another hinged kinematic pair P, which is connected to kinematic pair M. Kinematic pair M is connected to slider 42. Kinematic pair M is a spherical pair, such as a fisheye bearing. The hinged kinematic pair P is specifically implemented through an eccentric shaft, see [link to documentation]. Figure 22 The rotation of the eccentric shaft enables the kinematic pair M to have a tapping function, which in turn causes the first massage arm 1 and the second massage arm 2 to have a tapping function. The eccentric shaft can have eccentric sections only at two points along its own axis to achieve the eccentric function. For example... Figure 22 As shown, the eccentric shaft is mounted on the movement 310 via two bearings. The eccentric shaft includes a non-eccentric section P1 and an eccentric section P2. The portion of the eccentric shaft between the two bearings is the non-eccentric section P1, and the two ends of the eccentric shaft are the eccentric sections P2. The kinematic pair M is mounted on the eccentric section P2.

[0126] In some embodiments, the massage arm mechanism further includes a sixth kneading shaft 14, and the second end of the first massage arm 1 is rotatably connected to the mechanism 310 via the sixth kneading shaft 14.

[0127] See Figure 22 The sixth kneading shaft 14 is, for example, a curved shaft, and its two ends, namely the bent sections W, are connected to the second end of the first massage arm 1. During the rotation of the sixth kneading shaft 14, the bent sections W also rotate, which causes the first massage arm 1 and the second massage arm 2 to have a swinging function.

[0128] When it is necessary to lift the first massage arm 1 and the second massage arm 2, the slider 42 moves along the S1 direction. See below for the entire process. Figure 23 The process is illustrated by the solid arrow. When it is necessary to lift the first massage arm 1 and the second massage arm 2, the slider 42 moves along the S2 direction. See [link to full process] for details. Figure 13 The process is indicated by the dashed arrow.

[0129] The massage arm mechanism provided by the above technical solution has a compact structure, requires fewer parts, has reliable drive, and can realize swing and tapping functions, making the functions of the first massage arm 1 and the second massage arm 2 more abundant.

[0130] In all the above embodiments, the massage arm mechanism includes a starting state and a raised state; When the massage arm mechanism is in its initial state, the first massage arm 1 and the second massage arm 2 are collinear, meaning their length directions are essentially the same. In this state, the massage arm mechanism is compact overall. For example, when stored in the seat back, this collinearity minimizes space occupation and does not hinder the normal use of the seat.

[0131] When the massage arm mechanism is in the raised state, the angle between the first massage arm 1 and the second massage arm 2 is less than 180°. In the raised state, the massage arms can conform to the contour of the human back, effectively massaging the back. In different embodiments, the transition from the initial state to the raised state is achieved through the coordinated action of the drive mechanism 4 and the linkage mechanism 3, thus meeting the massage function requirements.

[0132] This invention also provides a seat, including the massage arm mechanism provided by any of the technical solutions of this invention.

[0133] The seat provided by the above technical solution includes a massage arm mechanism. Utilizing the start-up and raised-up state switching function of the massage arm mechanism, when the massage function is not in use, the massage arm mechanism is in the start-up state, with the first massage arm 1 and the second massage arm 2 collinear and compactly hidden within the seat back, without affecting the normal use and appearance of the seat. When the massage function is needed, the massage arm mechanism enters the raised state, with the first massage arm 1 and the second massage arm 2 forming an angle of less than 180°, conforming to the occupant's back. Through the movement of the massage head and the coordinated movement of the massage arms, a comfortable massage experience is provided to the occupant, enhancing the functionality and comfort of the seat.

[0134] Another embodiment of the present invention provides a vehicle, including a massage arm mechanism provided by any of the technical solutions of the present invention, or including a seat provided by any of the technical solutions of the present invention.

[0135] The vehicle provided by the above technical solution can meet the needs of drivers and passengers for massage and relaxation during vehicle use, making the vehicle not only a means of transportation, but also a comfortable mobile space, thus improving the overall performance of the vehicle.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0137] In the description of this invention, each technical feature may be combined with other technical features where feasible.

[0138] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
