Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

The following description is given to enable any person skilled in the art to make and use the invention. In the following description, details are listed for the purpose of explanation. It should be understood that one of ordinary skill in the art will recognize that the invention can be practiced without these specific details.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

[0033] At present, in order to improve the user experience, car seats are usually equipped with massage functions to relieve the user's driving fatigue through massage.

[0034] In related technologies, the massage function of car seats usually uses air bags or mechanical massage heads for massage. Among them, air bag massage mainly massages the human back by inflating and deflating the air bags, while mechanical massage heads massage the human back through the tapping and kneading movements of the massage heads.

[0035] Relatively speaking, air bag massage has the advantages of simple structure, small seat space occupation, and is conducive to reducing seat thickness and increasing the interior space of the car. However, air bag massage has the disadvantages of weak massage force and poor massage effect. Mechanical massage head has the advantages of strong massage force and good massage effect, but mechanical massage head has the disadvantages of complex structure, large seat space occupation, and is not conducive to reducing seat thickness.

[0036] Mechanical massage heads are increasingly used in car seats due to their effectiveness. However, when subjected to external forces, such as those generated in a collision, these mechanical massage heads can cause harm.

[0037] To this end, embodiments of the present application provide a massage device, a car seat, and a car, which are described in detail below.

[0038] First, see Figure 1 , Figure 1 A schematic structural diagram of a massage device 100 in an embodiment of the present application is shown, wherein the massage device 100 includes at least one first swing arm 10 , at least one first massage head 20 and a driving mechanism 30 .

[0039] Specifically, the first swing arm 10 can rotate around the first axis X, and the first massage head 20 is mounted on the first swing arm 10, so that the first massage head 20 can massage the back of the human body through the movement of the first swing arm 10. For example, the first swing arm 10 can swing back and forth around the first axis X, and the first massage head 20 can contact the back of the human body in a manner similar to knocking or pressing, so as to achieve a pressing or knocking massage process on the back of the human body; for example, in some possible embodiments, the first swing arm 10 can swing back and forth in a direction perpendicular to the first axis X, so that Figure 1 The two first massage heads 20 move in a circular motion between approaching and moving away from each other. At this time, the first massage heads 20 move left and right on the back of the human body to achieve a kneading massage process on the back of the human body.

[0040] It should be noted that the shape of the first swing arm 10 is usually approximately a strip-shaped "I" shape, one end of the first swing arm 10 is a rotating connection end, and the other end is used to install the first massage head 20, but it is not limited to this. For example, the shape of the first swing arm 10 can also be a "Y" shape, and one first swing arm 10 can fix two first massage heads 20.

[0041] For example, the first massage head 20 may include a component made of an elastic material such as hard silicone, soft silicone, and EVA foam. The elastic component of the first massage head 20 may improve the user's contact comfort.

[0042] The drive mechanism 30 is connected to the first swing arm 10 and is used to drive the first swing arm 10 to move. For example, the drive mechanism 30 can drive the first swing arm 10 to swing back and forth about the first axis X to achieve a pressing or tapping massage process on the human back. For another example, the drive mechanism 30 can drive the first swing arm 10 to swing back and forth in a direction perpendicular to the first axis X to achieve a kneading massage process on the human back.

[0043] As an exemplary embodiment, see Figure 2 , Figure 2 A schematic diagram of a massage device 100 in an embodiment of the present application is shown, wherein the drive mechanism 30 includes a telescopic rod, and the telescopic movement of the telescopic rod drives the first swing arm 10 to rotate about the first axis X. The telescopic rod can be, but is not limited to, a hydraulic telescopic rod, a pneumatic telescopic rod, or an electric telescopic rod.

[0044] As another exemplary embodiment, see Figure 3 , Figure 3 Another schematic diagram of the massage device 100 in an embodiment of the present application is shown, wherein the driving mechanism 30 includes a moving component 31, a fixed component 32 and a connecting rod 33, a first end of the connecting rod 33 is rotatably connected to the first swing arm 10, and a second end of the connecting rod 33 is rotatably connected to the moving component 31, and the moving component 31 can move along a preset straight line relative to the fixed component 32. When the moving component 31 moves, the connecting rod 33 can pull the first swing arm 10 to rotate around the first axis X.

[0045] It is understood that the embodiment of the driving mechanism 30 is not limited to this. Those skilled in the art can make adaptive adjustments to the driving mechanism 30 according to actual needs (such as the number of first swing arms 10, etc.). For example, the driving mechanism 30 can include but is not limited to hydraulic telescopic rods, pneumatic telescopic rods, electric telescopic rods, ball screws, gear racks and other linear motion mechanisms; for example, see Figure 4 , Figure 4 Another schematic diagram of the massage device 100 in an embodiment of the present application is shown, wherein the massage device 100 includes two first swing arms 10, and the driving mechanism 30 includes two moving components 31, and the two moving components 31 can respectively drive the two first swing arms 10 to rotate.

[0046] It should be noted that, see Figure 5 , Figure 5 A movement schematic diagram of the massage device 100 in an embodiment of the present application is shown, wherein the first swing arm 10 has a first rotation position away from the drive mechanism 30 and a second rotation position close to the drive mechanism 30. The first rotation position is the position of the first swing arm 10 when the massage device 100 is performing a massage. At this time, the first swing arm 10 is in an extended state away from the drive mechanism 30, so that the first massage head 20 on the first swing arm 10 can contact the back of the human body and perform a massage; the second rotation position is the position of the first swing arm 10 when the massage device 100 stops massaging. At this time, the second swing arm 40 is in a retracted state adjacent to the drive mechanism 30, so that the first swing arm 10 can be retracted to stop the massage.

[0047] In an embodiment of the present application, when the abuse force applied to the automobile exceeds a preset threshold, the drive mechanism 30 can release the rotation restriction on the first swing arm 10 within a preset time, and the preset time is less than or equal to 100ms, so that the first swing arm 10 can rotate freely in a short time after the automobile collision accident. When the first swing arm 10 is in a free rotation state, the force exerted on the back of the human body by the automobile collision will rotate in a direction that does not conflict with the back of the human body, thereby avoiding the phenomenon that the first swing arm 10 causes harm to the human body.

[0048] For example, see Figure 5 When the car is in a non-collision accident, the fixed component 32 drives the movable component 31 to move, and the position of the movable component 31 is controlled by the fixed component 32, so the first swing arm 10 is also controlled by the fixed component 32; when the first swing arm 10 is near the first rotation position and when the abuse force applied to the car exceeds a preset threshold, the driving mechanism 30 releases the rotation restriction on the first swing arm 10 within a preset time. At this time, the position of the movable component 31 is no longer controlled by the fixed component 32, and the movable component 31 can move freely left and right, so that the first swing arm 10 can be freely rotated from the first rotation position to the second rotation position. Since the second rotation position of the first swing arm 10 is adjacent to the driving mechanism 30 and is in a retracted state, the first swing arm 10 will abut against the back of the human body due to a collision accident of the car, thereby causing injury.

[0049] It should be noted that releasing the rotation restriction on the first swing arm 10 means that the rotation position of the first swing arm 10 is no longer controlled by the driving mechanism 30, but the first swing arm 10 is free to rotate. Figure 5 The position of the movable component 31 shown is no longer controlled by the fixed component 32 and can slide freely left and right. It can also release the rotational connection between the connecting rod 33 and the movable component 31, or release the rotational connection between the connecting rod 33 and the first swing arm. Those skilled in the art can make adaptive modifications and adjustments according to actual needs.

[0050] It is worth noting that the "preset threshold" is used to limit the response behavior of the massage device 100 when the car is subjected to abnormal external forces (such as impact, squeezing, and other abusive forces) to ensure human safety. The preset threshold can be set based on the force sensing unit provided in the massage device 100 or the car seat. Specifically, the force sensing unit can be any combination of one or more of the following components: strain gauges, accelerometers, force sensors, piezoelectric sensors, Hall elements, etc., which are used to monitor the external load or acceleration borne by the seat body, massage device 100, or its components in real time. The preset threshold can be set based on any one or more of the following parameters: 1. The maximum safe force that the driver or passenger can withstand under normal use; 2. The maximum allowable structural load that will not be triggered during normal driving; 3. The critical impact force or acceleration value extracted from the car crash test or extreme abuse test; 4. The safety limit value specified in the national or industry standard (such as the maximum allowable back pressure in the occupant protection standard).

[0051] It can be understood that once it is detected that the external force exceeds the preset threshold, the drive mechanism 30 will automatically release the rotation drive or rotation retention restriction on the first swing arm 10, thereby allowing the first massage head 20 to detach from or give way to the back area of the human body, reducing the risk of human body crushing or internal injury caused by the mechanical rigid structure.

[0052] Through the above-mentioned method, the safety of the massage device 100 in emergency or extreme situations can be effectively improved, while avoiding false triggering in normal conditions.

[0053] At the same time, it is worth noting that, in the present invention, "abuse force" refers to an external force acting on the massage device 100 or the car seat under abnormal use conditions, which usually exceeds the safety design range of the massage device 100 under normal working conditions and may cause structural damage or pose potential safety hazards to the occupants.

[0054] Abuse force may include but is not limited to external forces generated by the following situations: 1. Inertial impact force or structural extrusion force generated in a car collision accident. For example, when the vehicle is subjected to a head-on collision, side collision, rear-end collision or rollover, the body structure deforms or decelerates instantly, and the seat system will be subjected to a high amplitude mechanical impact; 2. The door or seat structure is subjected to a strong external impact or compression, such as a passenger stepping violently, or the cargo behind the seat violently colliding with the backrest; 3. The impact of the passenger's body inertia on the seat back during emergency braking or large turns; 4. Children or abnormal users exert violent pulling, knocking, kicking, etc. on the massage device 100 when the vehicle is stationary; 5. Structural deformation, impact, heavy falls, etc. that occur during transportation, handling, and maintenance.

[0055] In the present invention, the drive mechanism 30 can identify through a sensor whether the above-mentioned abuse force exceeds the safety threshold set by the system, and when the threshold is exceeded, the restrictive connection or driving relationship between the massage structure (such as the first swing arm 10) and the drive mechanism 30 is promptly released, so that the massage structure becomes a non-mandatory constraint state, thereby minimizing the risk of injury to the occupant's back.

[0056] In some embodiments of the present application, after the driving mechanism 30 releases the rotation restriction on the first swing arm 10, the driving mechanism 30 further applies a first driving force to the first swing arm 10 indirectly or directly; wherein the first driving force is configured to accelerate the first swing arm 10 from the first rotation position to the second rotation position. For example, see Figure 6 , Figure 6 Another schematic diagram of the massage device 100 in an embodiment of the present application is shown, wherein, after the driving mechanism 30 releases the rotation restriction on the first swing arm 10, the movable component 31 can slide freely left and right, and the electromagnet generates a magnetic force F1 to attract the movable component 31 to slide to the left, thereby accelerating the rotation of the first swing arm 10 from the first rotation position to the second rotation position.

[0057] In some embodiments of the present application, when the abuse force applied to the vehicle exceeds a preset threshold, the drive mechanism 30 can release the rotation restriction on the first swing arm 10 in response to an electronic signal indicating a collision of the vehicle, so as to avoid the phenomenon that the first swing arm 10 causes harm to the human body when the first swing arm 10 is in the first rotation position.

[0058] For example, the electronic signal indicating a car collision may be, but is not limited to, an electronic signal emitted by an electronic control unit (ECU) of a car when detecting a car collision.

[0059] As an exemplary embodiment, the driving mechanism 30 includes a moving component 31, a connecting rod 33 and a fixing component 32. Figure 7 , Figure 7 Another schematic diagram of the massage device 100 in an embodiment of the present application is shown, wherein the moving component 31 includes a first slider 311 and a second slider 312, and an electromagnetic coil that generates magnetic force can be set in the first slider 311 and / or the second slider 312; the second end of the connecting rod 33 is rotatably connected to the first slider 311, and the second slider 312 is magnetically attracted to the first slider 311.

[0060] When the car has not been involved in a collision accident, the fixing assembly 32 drives the second slider 312 to move. Since the second slider 312 is magnetically attracted to the first slider 311, the first slider 311 can move along with the second slider 312, thereby driving the first swing arm 10 to swing through the connecting rod 33 to massage the back of the human body; when the abuse force applied to the car exceeds a preset threshold, the electronic signal of the car collision controls the electromagnetic coil generating magnetic force in the first slider 311 and / or the second slider 312 to be powered off, and then the magnetic force of mutual attraction between the first slider 311 and the second slider 312 disappears. At this time, the first slider 311 can slide freely left and right, so the connecting rod 33 and the first swing arm 10 can rotate freely, so that the first swing arm 10 can rotate freely from the first rotation position to the second rotation position to avoid injury to the human body.

[0061] In some embodiments of the present application, for example, the second slider 312 and the first slider 311 can be magnetically attracted to each other, see Figure 7 , Figure 7 Another movement diagram of the massage device 100 in the embodiment of the present application is shown, wherein, after the magnetic force of mutual attraction between the second slider 312 and the first slider 311 disappears, a mutually repulsive magnetic force F can be generated between the first slider 311 and the second slider 312. The first slider 311 can move to the left under the action of the magnetic force F, thereby accelerating the rotation of the first swing arm 10 from the first rotation position to the second rotation position.

[0062] In some embodiments of the present application, when the abuse force applied to the automobile exceeds a preset threshold, the drive mechanism 30 can release the rotation restriction on the first swing arm 10 in response to the force transmitted by the first swing arm 10, so as to avoid the phenomenon that the first swing arm 10 causes harm to the human body when it is in the first rotation position.

[0063] In some embodiments of the present application, Figure 8 The second end of the connecting rod is rotatably connected to the first slider 311. A first lug 3111 is provided on the side of the first slider 311 close to the second slider 312, and a second lug 3121 is provided on the side of the second slider 312 close to the first slider 311. The first lug 3111 and the second lug 3121 are both provided with corresponding sockets, and an electromagnetic pin 50 is inserted into the socket; wherein, when the abuse force applied to the vehicle exceeds a preset threshold, the electromagnetic pin 50 is withdrawn from the socket under the electromagnetic action to release the locking relationship between the first slider 311 and the second slider 312, so that the first slider 311 can move relative to the second slider 312 in a preset direction.

[0064] As an example, see Figure 9 , Figure 9Another schematic diagram of the massage device 100 in an embodiment of the present application is shown, wherein the moving component 31 includes a first slider 311 and a second slider 312; the second end of the connecting rod 33 is rotatably connected to the first slider 311, and the second slider 312 is indirectly or directly engaged with the first slider 311.

[0065] When the car has not been involved in a collision accident, the fixing assembly 32 drives the second slider 312 to move. Since the second slider 312 is indirectly or directly engaged with the first slider 311, the first slider 311 can move along with the second slider 312, thereby driving the first swing arm 10 to swing through the connecting rod 33 to massage the back of the human body; when the abuse force applied to the car exceeds a preset threshold, the force transmitted by the first swing arm 10 causes the first slider 311 and the second slider 312 to release the engagement state and separate from each other. At this time, the first slider 311 can slide freely left and right, so the connecting rod 33 and the first swing arm 10 can rotate freely, so that the first swing arm 10 can rotate freely from the first rotation position to the second rotation position to avoid injury to the human body.

[0066] In some embodiments of the present application, the driving mechanism 30 can release the rotation restriction on the first swing arm 10 in response to at least one of the electronic signal of a car collision and the force transmitted by the first swing arm 10, so as to avoid the phenomenon of causing harm to the human body when the first swing arm 10 is in the first rotation position.

[0067] As an example, see Figure 10 , Figure 10 Another schematic diagram of the massage device 100 according to an embodiment of the present application is shown, wherein the moving assembly 31 includes a first slider 311, a second slider 312, and a third slider 313. An electromagnetic coil generating a magnetic force may be disposed in the second slider 312 and / or the third slider 313. The second end of the connecting rod 33 is rotatably connected to the first slider 311, the second slider 312 is indirectly or directly engaged with the first slider 311, and the third slider 313 is magnetically attracted to the second slider 312. When the car has not collided, the fixing assembly 32 drives the third slider 313 to move. Since the second slider 312 is engaged with the first slider 311 indirectly or directly, and the second slider 312 and the third slider 313 are magnetically attracted, the first slider 311 can move along with the second slider 312 and the third slider 313, thereby driving the first swing arm 10 to swing through the connecting rod 33 to massage the back of the human body. When the abuse force applied to the car exceeds a preset threshold, the electronic signal of the car collision cuts off the power to the electromagnetic coil generating the magnetic force in the second slider 312 and / or the third slider 313, and the magnetic force of mutual attraction between the second slider 312 and the third slider 313 is eliminated. When the vehicle is lost, the first slider 311 and the second slider 312 can slide freely, so the connecting rod 33 and the first swing arm 10 can rotate freely, so that the first swing arm 10 can rotate freely from the first rotation position to the second rotation position to avoid injury to the human body; or, when the abuse force applied to the vehicle exceeds a preset threshold, the force transmitted by the first swing arm 10 causes the first slider 311 and the second slider 312 to release the engagement state and separate from each other. At this time, the first slider 311 can slide freely, so the connecting rod 33 and the first swing arm 10 can rotate freely, so that the first swing arm 10 can rotate freely from the first rotation position to the second rotation position to avoid injury to the human body.

[0068] As a specific structural exemplary embodiment of the massage device 100, refer to Figure 11 , Figure 11 An exploded schematic diagram of the massage device 100 in an embodiment of the present application is shown. The driving mechanism 30 includes a moving component 31, a fixed component 32 and a connecting rod 33. The first swing arm 10 is rotatably mounted on the fixed component. The first end of the connecting rod 33 is rotatably connected to the first swing arm 10, and the second end of the connecting rod 33 is rotatably connected to the moving component 31. The moving component 31 can move along a preset straight line relative to the fixed component 32. When the moving component 31 moves, the connecting rod 33 can pull the first swing arm 10 to rotate around the first axis X.

[0069] In some embodiments of the present application, see Figure 11 as well as Figure 12 , Figure 12A structural schematic diagram of the moving component 31 in an embodiment of the present application is shown, wherein the moving component 31 includes a first slider 311 and a second slider 312, and the moving component 31 is installed with a first eccentric rotating shaft 314 and a first motor 315, the first eccentric rotating shaft 314 and the first motor 315 are installed on the first slider 311, and the second slider 312 is driven by the fixed component 32 to drive the first slider 311 to move; the connecting rod 33 is rotatably installed on the first eccentric rotating shaft 314, and the first motor 315 is used to drive the first eccentric rotating shaft 314 to rotate, so that the first connecting rod 33 drives the first swing arm 10 to swing back and forth around the first axis X, at this time, the first massage head 20 contacts the back of the human body in a manner similar to knocking or pressing, so as to realize a pressing or knocking massage process on the back of the human body.

[0070] As an example, see Figure 11 as well as Figure 13 , Figure 13 An exploded schematic diagram shows a partial structure of the moving component 31 in an embodiment of the present application. An eccentric wheel 3141 is provided on the first eccentric rotating shaft 314, and the connecting rod 33 is fixed on the eccentric wheel 3141. During the rotation of the first eccentric rotating shaft 314, the eccentric wheel 3141 can drive one end of the connecting rod 33 to perform eccentric movement, thereby driving the first swing arm 10 to swing back and forth around the first axis X to achieve a pressing or tapping massage process on the human back.

[0071] It can be understood that in some possible embodiments, the fixed component 32 drives the movable component 31 to move back and forth, and the connecting rod 33 can also drive the first swing arm 10 to swing back and forth around the first axis X to achieve a pressing or tapping massage process on the human back.

[0072] In some embodiments of the present application, see Figure 11 and 14, Figure 14 A structural schematic diagram of the connecting rod 33 in an embodiment of the present application is shown, wherein the connecting rod 33 includes a sleeve 332 and a connecting rod 331; the sleeve 332 is installed on the first eccentric shaft 314, the first end of the connecting rod 331 is rotatably connected to the sleeve 332, and the second end of the connecting rod 331 is hinged to the first swing arm 10; wherein the first connecting rod 331 can rotate around the second axis Y relative to the sleeve 332, and the second axis Y is perpendicular to the first axis X.

[0073] Specifically, when the sleeve 332 rotates on the first eccentric shaft 314, the connecting rod 33 rotates relative to the third axis Z parallel to the first axis X, so that the connecting rod 33 drives the first swing arm 10 to rotate around the first axis X, thereby realizing the lifting, lowering or reciprocating swinging motion of the first swing arm 10 around the first axis X; and when the first swing arm 10 reciprocates in a direction perpendicular to the first axis X, the connecting rod 331 can also rotate relative to the sleeve 332 around the second axis Y perpendicular to the first axis X. At this time, the connecting rod 33 will not limit the reciprocating swinging of the first swing arm 10 in the direction perpendicular to the first axis X. During the reciprocating swinging of the first swing arm 10 in the direction perpendicular to the first axis X, the first massage head 20 contacts the back of the human body by moving left and right, so as to realize the kneading and massaging process of the human body's back, thereby avoiding the phenomenon that the connecting rod 33 limits the first swing arm 10 from driving the first massage head 20 to knead and massage the back of the human body.

[0074] In some embodiments of the present application, for example, for an embodiment in which the first slider 311 and the second slider 312 are indirectly engaged, see Figure 15 , Figure 15 Another exploded schematic diagram of the partial structure of the moving component 31 in the embodiment of the present application is shown, wherein the moving component 31 includes a first slider 311, a second slider 312 and a hook 317, the hook 317 is fixed on the second slider 312, and the hook 317 is engaged with the second slider 312.

[0075] When the car has not been involved in a collision accident, the fixing assembly 32 drives the second slider 312 to move. Since the second slider 312 is indirectly engaged with the first slider 311 through the hook 317, the first slider 311 can move along with the second slider 312, thereby driving the first swing arm 10 to swing through the connecting rod 33 to massage the back of the human body; when the abuse force applied to the car exceeds a preset threshold, the force transmitted by the first swing arm 10 causes the hook 317 fixing the first slider 311 and the second slider 312 to release the engagement state and separate from each other. At this time, the first slider 311 can slide freely, so the connecting rod 33 and the first swing arm 10 can rotate freely, so that the first swing arm 10 can rotate freely from the first rotation position to the second rotation position to avoid injury to the human body.

[0076] In some embodiments of the present application, see Figure 12 as well as Figure 16 , Figure 16A structural schematic diagram of the fixed component 32 in an embodiment of the present application is shown, wherein the fixed component 32 includes a base plate 321, a drive shaft 323 and a second motor 322, the drive shaft 323 and the second motor 322 are installed on the base plate 321, the drive shaft 323 has a screw portion 3231, and the moving component 31 is fixed with a nut 316, which cooperates with the screw portion 3231; the drive shaft 323 is rotatably installed on the base plate 321, and the second motor 322 is used to drive the drive shaft 323 to rotate. During the rotation of the drive shaft 323, the nut 316 moves on the screw portion 3231 of the drive shaft 323, thereby driving the nut 316 and driving the moving component 31 to move, and finally causing the moving component 31 to move relative to the base plate 321 along a preset direction, and pulling the first swing arm 10 to move through the connecting rod 33.

[0077] In some embodiments of the present application, see Figure 11 as well as Figure 16 The substrate 321 is also equipped with a second eccentric shaft 324; the first swing arm 10 is rotatably mounted on the second eccentric shaft 324, and the second motor 322 is also used to drive the second eccentric shaft 324 to rotate; wherein, when the second motor 322 drives the second eccentric shaft 324 to rotate, the first swing arm 10 swings back and forth around a direction perpendicular to the first axis X.

[0078] It should be noted that, combined with Figure 14 As can be seen from the structure of the connecting rod 33, during the reciprocating swing of the first swing arm 10 in a direction perpendicular to the first axis X, the connecting rod 33 does not restrict the reciprocating swing of the first swing arm 10 in the direction perpendicular to the first axis X. During this time, the first massage head 20 engages the back of the person by moving left and right, thereby providing a kneading massage of the back. Furthermore, because the second motor 322 not only drives the moving assembly 31 in a predetermined direction but also drives the first swing arm 10 to reciprocate about the direction perpendicular to the first axis X, the number of motors in the massage device 100 is reduced, thereby lowering the cost of the massage device 100 and reducing the space occupied by the massage device 100 within the seat.

[0079] As an exemplary embodiment of a motor driving the first swing arm 10 to swing back and forth in a direction perpendicular to the first axis X, refer to Figure 17 , Figure 17 An exploded schematic diagram of the fixing assembly 32 in an embodiment of the present application is shown, wherein a turbine 325 is mounted on the second eccentric shaft 324, and the drive shaft 323 also has a worm portion 3232. The turbine 325 cooperates with the worm portion 3232. During the rotation of the drive shaft 323, the worm portion 3232 drives the turbine 325 to rotate, thereby rotating the second eccentric shaft 324, and finally drives the first swing arm 10 to swing back and forth around a direction perpendicular to the first axis X through the second eccentric shaft 324.

[0080] In some embodiments of the present application, see Figure 18 , Figure 18 An exploded schematic diagram of the connecting rod 33 and the first swing arm 10 in the embodiment of the present application is shown, wherein the first swing arm 10 has a ball socket 101, and the second end of the connecting rod 33 is provided with a ball head 3301, and the ball head 3301 fits with the ball socket 101, that is, the connecting rod 33 is connected to the ball socket 101 of the first swing arm 10 through the ball head 3301 to form a ball joint. Figure 14 From the structure of the connecting rod 33 , it can be seen that the first swing arm 10 can not only rotate around the first axis X through the cooperation between the ball head 3301 and the ball socket 101 , but also can swing back and forth in a direction perpendicular to the first axis X.

[0081] In some embodiments of the present application, see Figure 19 , Figure 19 A structural schematic diagram of the connecting rod 33 and the first swing arm 10 in an embodiment of the present application is shown, wherein the ball socket 101 passes through the first swing arm 10, the second end of the connecting rod 33 passes through the ball socket 101 and is installed with the second swing arm 40, and the second swing arm 40 is installed with the second massage head 50 at the end facing away from the first end of the connecting rod 33. In other words, a larger number of massage heads can be installed on the second swing arm 40 fixed by the connecting rod 33, so as to provide the user with a richer massage experience through the first massage head 20 and the second massage head 50.

Those skilled in the art can also make equivalent modified designs or further designs under the guidance of the present application.

The third motor 326 may be used as a motor to drive the entire massage device 100 to move inside the seat so as to massage different parts of the human body.
