Technical Field

[0001] This application relates to the field of automotive technology, specifically to a massage device, a car seat, and a car. Background Technology

[0002] Currently, to enhance the user experience, car seats are typically equipped with massage functions to alleviate driving fatigue. In related technologies, car seat massage functions usually employ air bags or mechanical massage heads. Air bag massage primarily uses the inflation and deflation of air bags to massage the back, while mechanical massage heads use tapping and kneading motions to massage the back.

[0003] However, when a car is subjected to externally induced abusive forces, such as those generated during a car collision, the mechanical massage heads that extend inside current car seats may cause injury to the human body. Utility Model Content

[0004] This application provides a massage device, a car seat, and a car, aiming to solve the above-mentioned technical problems.

[0005] In a first aspect, this application provides a massage device applied to a car seat, comprising: At least one first swing arm, the first swing arm being rotatable about a first axis, and the first swing arm being equipped with a first massage head; A drive mechanism is connected to the first swing arm and is used to drive the first swing arm to rotate around the first axis. The drive mechanism is configured to release the rotation restriction on the first swing arm when the abuse force on the vehicle exceeds a preset threshold.

[0006] In some embodiments, the first swing arm has a first rotational position away from the drive mechanism and a second rotational position close to the drive mechanism; When the first swing arm is near the first rotation position and the abusive force on the vehicle exceeds a preset threshold, the drive mechanism releases the rotation restriction on the first swing arm within a preset time, so that the first swing arm can freely rotate from the first rotation position to the second rotation position.

[0007] In some embodiments, after the drive mechanism releases the rotation restriction on the first swing arm, the drive mechanism also indirectly or directly applies a first driving force to the first swing arm. The first driving force is configured to accelerate the first swing arm from the first rotation position to the second rotation position.

[0008] In some embodiments, when the abusive force on the vehicle exceeds a preset threshold, the drive mechanism releases the rotation restriction on the first swing arm in response to the force transmitted by the first swing arm.

[0009] In some embodiments, when the abusive force on the vehicle exceeds a preset threshold, the drive mechanism releases the rotation restriction on the first swing arm in response to an electronic signal indicating a collision.

[0010] In some embodiments, when the abusive force on the vehicle exceeds a preset threshold, the drive mechanism releases the rotation restriction on the first swing arm in response to at least one of the electronic signal of a vehicle collision and the force transmitted by the first swing arm.

[0012] In some embodiments, the moving component includes a first slider and a second slider; The second end of the connecting rod is rotatably connected to the first slider, and the second slider is magnetically attracted to the first slider. When the abuse force applied to the car exceeds a preset threshold, the magnetic force attracting the first and second sliders disappears.

[0013] In some embodiments, after the magnetic force that attracts the second slider and the first slider disappears, a magnetic force that repels the first slider and the second slider is generated.

[0014] In some embodiments, the moving component includes a first slider and a second slider; The second end of the connecting rod is rotatably connected to the first slider, and the second slider is indirectly or directly engaged with the first slider. When the abuse force on the car exceeds a preset threshold, the first slider and the second slider separate.

[0015] In some embodiments, the moving component includes a first slider, a second slider, and a third slider; The second end of the connecting rod is rotatably connected to the first slider, the second slider is indirectly or directly engaged with the first slider, and the third slider is magnetically attracted to the second slider. When the abuse force on the car exceeds a preset threshold, the first slider and the second slider separate from each other, or the magnetic force attracting the second slider and the third slider disappears.

[0016] In some embodiments, the moving component is equipped with a first eccentric shaft and a first motor; The connecting rod is rotatably mounted on the first eccentric shaft, and the first motor is used to drive the first eccentric shaft to rotate, so that the connecting rod drives the first swing arm to swing back and forth around the first axis.

[0017] In some embodiments, the connecting rod includes a bushing and a connecting rod; The bushing is mounted on the first eccentric rotating shaft, the first end of the connecting rod is rotatably connected to the bushing, and the second end of the connecting rod is hinged to the first swing arm. The connecting rod can rotate relative to the bushing about a second axis, which is perpendicular to the first axis.

[0018] In some embodiments, the movable component includes a first slider, a second slider, and a latch; The hook is fixed to the second slider and engages with the first slider.

[0019] In some embodiments, the fixing component includes a base plate, a drive shaft, and a second motor, wherein the drive shaft and the second motor are mounted on the base plate; The drive shaft has a lead screw section, and the moving component is fixed with a lead screw nut, which cooperates with the lead screw section. The drive shaft is rotatably mounted on the base plate, and the second motor is used to drive the drive shaft to rotate, thereby driving the nut to move the moving component.

[0020] In some embodiments, the substrate is further mounted with a second eccentric rotating shaft; The first swing arm is rotatably mounted on the second eccentric shaft, and the second motor is also used to drive the second eccentric shaft to rotate. When the second motor drives the second eccentric shaft to rotate, the first swing arm swings back and forth around the direction perpendicular to the first axis.

[0021] In some embodiments, a turbine is mounted on the second eccentric shaft; The drive shaft also has a worm gear section, with the worm gear engaging with it.

[0022] In some embodiments, the first swing arm has a ball socket, and the second end of the connecting rod has a ball head that fits into the ball socket.

[0023] In some embodiments, the ball socket extends through the first swing arm; The second end of the connecting rod passes through the ball socket and is fitted with a second swing arm. The second swing arm is mounted with a second massage head away from the first end of the connecting rod.

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0033] Currently, in order to improve the user experience, car seats are usually equipped with massage functions to relieve driving fatigue.

[0034] In related technologies, the massage function of car seats usually uses air bags or mechanical massage heads. Air bag massage mainly achieves back massage by inflating and deflating air bags, while mechanical massage heads achieve back massage by tapping and kneading motions.

[0035] In comparison, airbag massage has advantages such as simple structure, small space occupation, and the ability to reduce seat thickness and increase car interior space, but it also has disadvantages such as weak massage intensity and poor massage effect. Mechanical massage head has advantages such as strong massage intensity and good massage effect, but it also has disadvantages such as complex structure, large space occupation, and not the ability to reduce seat thickness.

[0036] Currently, mechanical massage heads are increasingly used in car seats due to their superior massage effects. However, when a car is subjected to external forces, such as those generated during a car collision, these mechanical massage heads may cause injury to the human body.

[0037] Therefore, this application provides a massage device, a car seat, and a car, which will be described in detail below.

[0038] First, refer to Figure 1 , Figure 1 A schematic diagram of a massage device 100 in an embodiment of this 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 drive mechanism 30.

[0039] Specifically, the first swing arm 10 is rotatable about 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 massages 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 about the first axis X, at which time the first massage head 20 contacts the back of the human body in a manner similar to tapping or pressing, so as to realize the pressing or tapping massage process of the back of the human body; as another 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 cyclical manner, moving closer and further apart from each other. At this time, the first massage heads 20 move left and right on the back of the human body to achieve the kneading massage process of 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. However, it is not limited to this. For example, the shape of the first swing arm 10 can also be "Y" shaped, 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 elastic materials such as hard silicone, soft silicone and EVA foam, and the elastic component of the first massage head 20 can 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 around the first axis X to realize the pressing or tapping massage process of the human back; or, 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 realize the kneading massage process of 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 this application is shown, wherein the drive mechanism 30 includes a telescopic rod, and the first swing arm 10 is driven to rotate around the first axis X by the telescopic movement of the telescopic rod. The telescopic rod may be, but is not limited to, a hydraulic telescopic rod, a pneumatic telescopic rod, or an electric telescopic rod.

[0044] As yet another exemplary embodiment, see Figure 3 , Figure 3 Another schematic diagram of the massage device 100 in this application embodiment is shown, wherein the drive mechanism 30 includes a moving component 31, a fixed component 32 and a connecting rod 33. 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 relative to the fixed component 32 along a preset straight line. Under the movement of the moving component 31, the connecting rod 33 can pull the first swing arm 10 to rotate around the first axis X.

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

[0046] It should be noted that, for reference Figure 5 , Figure 5 This illustration shows a motion diagram of the massage device 100 in an embodiment of this application. The first swing arm 10 has a first rotational position away from the drive mechanism 30 and a second rotational position close to the drive mechanism 30. The first rotational position is the position of the first swing arm 10 when the massage device 100 is performing massage. At this time, the first swing arm 10 is extended 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 massage. The second rotational 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 retracted near the drive mechanism 30 so that the first swing arm 10 can be retracted to stop the massage.

[0047] In this embodiment of the application, when the abuse force on the car exceeds a preset threshold, the drive mechanism 30 can release the rotation restriction on the first swing arm 10 within a preset time. The preset time is less than or equal to 100ms, so that the first swing arm 10 can rotate freely for a short time after the car collision. When the first swing arm 10 is in a free rotation state, the force applied to the back of the person who is hit by the car will rotate in a direction that does not resist the back of the person, thereby avoiding the phenomenon that the first swing arm 10 causes harm to the person.

[0048] For example, see Figure 5 When a non-collision accident occurs, the fixed component 32 drives the moving component 31 to move. The position of the moving 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 the abusive force on the car exceeds a preset threshold, the drive mechanism 30 releases the rotation restriction on the first swing arm 10 within a preset time. At this time, the position of the moving component 31 is no longer controlled by the fixed component 32, and the moving component 31 can move freely left and right, so that the first swing arm 10 can freely rotate 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 drive mechanism 30 and is in a retracted state, the phenomenon of the first swing arm 10 coming into contact with the back of the human body due to a car collision accident will occur, resulting in injury.

[0049] It should be noted that releasing the rotation restriction on the first swing arm 10 means that the rotational position of the first swing arm 10 is no longer controlled by the drive mechanism 30, but is allowed to rotate freely. Releasing the rotation restriction on the first swing arm 10 can be achieved by... 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. Alternatively, the rotational connection between the link 33 and the movable component 31 can be released, or the rotational connection between the link 33 and the first swing arm can be released. 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 vehicle is subjected to abnormal external forces (such as impact, squeezing, or other abusive forces) to ensure human safety. This preset threshold can be set based on a force sensing unit installed in the massage device 100 or the vehicle seat. Specifically, the force sensing unit can be any combination of one or more of the following components: strain gauges, acceleration sensors, force sensors, piezoelectric sensors, Hall effect elements, etc., used to monitor in real time the external load or acceleration borne by the seat body, massage device 100, or its components. This 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 permissible structural load that will not be triggered during normal driving; 3. The critical value of impact force or acceleration extracted from vehicle crash tests or extreme abuse tests; 4. Safety limits specified in national or industry standards (such as the maximum permissible back pressure in occupant protection standards).

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

[0052] The above methods can effectively improve the safety of the massage device 100 in emergency or extreme situations, while avoiding accidental triggering under normal conditions.

[0053] Meanwhile, it is worth noting that in this utility model, "abuse force" refers to external force applied to the massage device 100 or 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 of force may include, but is not limited to, the following external forces: 1. Inertial impact or structural compression force generated in a car collision, such as when a vehicle is subjected to a frontal collision, side collision, rear-end collision or rollover, the vehicle body structure deforms or decelerates instantly, and the seat system will be subjected to a high degree of mechanical impact; 2. The door or seat structure is subjected to strong external impact or pressure, such as a passenger violently stepping on it, or cargo behind the seat violently hitting the backrest; 3. The impact of the occupant's body inertia on the seat back caused by emergency braking or sharp turning; 4. Violent pulling, knocking, or kicking of the massage device 100 by children or abnormal users when the vehicle is stationary; 5. Structural deformation, impact, or heavy drop that occurs during transportation, handling, or maintenance.

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

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

[0057] In some embodiments of this application, when the abuse force on the vehicle exceeds a preset threshold, the drive mechanism 30 can release the rotation restriction on the first swing arm 10 in response to the electronic signal of the vehicle collision, 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.

[0058] For example, the electronic signal of a car collision can be, but is not limited to, the electronic signal emitted by the Electronic Control Unit (ECU) when it detects a car collision.

[0059] As an exemplary embodiment, taking the drive mechanism 30 including a moving component 31, a connecting rod 33, and a fixed component 32 as an example, see [link to documentation]. Figure 7 , Figure 7 Another schematic diagram of the massage device 100 in an embodiment of this application is shown, wherein the moving component 31 includes a first slider 311 and a second slider 312, and an electromagnetic coil for generating magnetic force may be provided 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 no collision occurs, the fixing component 32 drives the second slider 312 to move. Since the second slider 312 and the first slider 311 are magnetically attracted, the first slider 311 can move with the second slider 312, thereby driving the first swing arm 10 to swing and massage the back of the human body through the connecting rod 33. When the abusive force on the car exceeds a preset threshold, the electronic signal of the car collision controls the electromagnetic coil that generates magnetic force in the first slider 311 and / or the second slider 312 to be de-energized. Then the magnetic force that attracts the first slider 311 and the second slider 312 disappears. At this time, the first slider 311 can slide freely left and right. Therefore, 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 causing harm to the human body.

[0061] In some embodiments of this application, such as embodiments where the second slider 312 and the first slider 311 can be magnetically engaged, see [reference]. Figure 7 , Figure 7 Another motion diagram of the massage device 100 in the embodiment of this application is shown, wherein after the magnetic force that attracts the second slider 312 and the first slider 311 disappears, a magnetic force F that repels each other can be generated between the first slider 311 and the second slider 312. Under the action of the magnetic force F, the first slider 311 can move to the left, so that the first swing arm 10 can accelerate from the first rotation position to the second rotation position.

[0062] In some embodiments of this application, when the abuse force on the vehicle 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 this application, combined with Figure 8 The second end of the connecting rod is rotatably connected to the first slider 311. The first slider 311 has a first lug 3111 on the side near the second slider 312, and the second slider 312 has a second lug 3121 on the side near the first slider 311. Both the first lug 3111 and the second lug 3121 have corresponding insertion holes, and an electromagnetic pin 60 is inserted into the insertion hole. When the abuse force on the car exceeds a preset threshold, the electromagnetic pin 60 is withdrawn from the insertion hole under 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 this 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 no collision occurs, the fixing component 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 with the second slider 312, thereby driving the first swing arm 10 to swing and massage the back of the human body through the connecting rod 33. When the abusive force on the car exceeds the preset threshold, the force transmitted by the first swing arm 10 causes the first slider 311 and the second slider 312 to disengage 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, allowing the first swing arm 10 to rotate freely from the first rotation position to the second rotation position to avoid causing harm to the human body.

[0066] In some embodiments of this application, the drive mechanism 30 may 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 that the first swing arm 10 causes injury to the human body when it is in the first rotation position.

[0067] As an example, see Figure 10 , Figure 10 Another schematic diagram of the massage device 100 in an embodiment of this application is shown, wherein the moving component 31 includes a first slider 311, a second slider 312 and a third slider 313, and an electromagnetic coil for generating magnetic force may be provided 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 no collision occurs, the fixing component 32 drives the third slider 313 to move. Since the second slider 312 is indirectly or directly engaged with the first slider 311, 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. This, in turn, drives the first swing arm 10 to swing and massage the back of the human body via the connecting rod 33. When the abusive force on the car exceeds a preset threshold, the electronic signal of the car collision de-energizes the electromagnetic coils that generate magnetic force in the second slider 312 and / or the third slider 313, thus eliminating the magnetic force attracting the second slider 312 and the third slider 313. In the event of a collision, the first slider 311 and the second slider 312 can slide freely, thus allowing the connecting rod 33 and the first swing arm 10 to rotate freely, enabling the first swing arm 10 to rotate freely from the first rotation position to the second rotation position to avoid causing harm to the human body; or, when the abusive force on 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 disengage and separate from each other, at which point the first slider 311 can slide freely, thus allowing the connecting rod 33 and the first swing arm 10 to rotate freely, enabling the first swing arm 10 to rotate freely from the first rotation position to the second rotation position to avoid causing harm to the human body.

[0068] As an exemplary embodiment of a specific structure of the massage device 100, see [reference]. Figure 11 , Figure 11 An exploded view of a massage device 100 in an embodiment of this application is shown. The drive 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 32. 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 relative to the fixed component 32 along a preset straight line. Under the movement of the moving component 31, the connecting rod 33 can pull the first swing arm 10 to rotate around the first axis X.

[0069] In some embodiments of this application, see Figure 11 as well as Figure 12 , Figure 12A schematic diagram of a moving component 31 in an embodiment of this application is shown. The moving component 31 includes a first slider 311 and a second slider 312. The moving component 31 is equipped with a first eccentric rotating shaft 314 and a first motor 315. The first eccentric rotating shaft 314 and the first motor 315 are mounted on the first slider 311. The second slider 312 is driven by the fixing component 32, thereby driving the first slider 311 to move. A connecting rod 33 is rotatably mounted on the first eccentric rotating shaft 314. The first motor 315 is used to drive the first eccentric rotating shaft 314 to rotate, so that the 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 an approximate tapping or pressing manner to realize the pressing or tapping massage process of the back of the human body.

[0070] As an example, see Figure 11 as well as Figure 13 , Figure 13 An exploded view of a portion of the structure of the moving component 31 in an embodiment of this application is shown. 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 realize the pressing or tapping massage process of the human back.

[0071] It is understandable that in some possible embodiments, the moving component 31 can be driven to move back and forth by the fixed component 32, which can also cause the connecting rod 33 to drive the first swing arm 10 to swing back and forth around the first axis X, so as to realize the pressing or tapping massage process on the back of the human body.

[0072] In some embodiments of this application, see Figure 11 And 14, Figure 14 A schematic diagram of a connecting rod 33 in an embodiment of this application is shown. The connecting rod 33 includes a bushing 332 and a connecting rod 331. The bushing 332 is mounted on a first eccentric rotating shaft 314. The first end of the connecting rod 331 is rotatably connected to the bushing 332, and the second end of the connecting rod 331 is hinged to the first swing arm 10. The connecting rod 331 can rotate relative to the bushing 332 about a second axis Y, and the second axis Y is perpendicular to the first axis X.

[0073] Specifically, when the bushing 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 can drive the first swing arm 10 to rotate around the first axis X, realizing the lifting, lowering or reciprocating swinging motion of the first swing arm 10 around the first axis X; when the first swing arm 10 reciprocates in the direction perpendicular to the first axis X, the connecting rod 331 can also rotate relative to the bushing 332 around the second axis Y perpendicular to the first axis X. At this time, the connecting rod 33 will not restrict the reciprocating swing of the first swing arm 10 in the direction perpendicular to the first axis X. During the reciprocating swing 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 in a left-right moving manner, so as to realize the kneading massage process of the back of the human body, thereby avoiding the phenomenon that the connecting rod 33 restricts 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 this application, such as embodiments where the first slider 311 and the second slider 312 are indirectly engaged, see [reference]. Figure 15 , Figure 15 Another exploded view of the structure of the movable component 31 in an embodiment of this application is shown. The movable component 31 includes a first slider 311, a second slider 312 and a hook 317. The hook 317 is fixed to the second slider 312 and engages with the first slider 311.

[0075] When no collision occurs, the fixing component 32 drives the second slider 312 to move. Since the second slider 312 and the first slider 311 are indirectly engaged through the hook 317, the first slider 311 can move with the second slider 312, thereby driving the first swing arm 10 to swing and massage the back of the human body through the connecting rod 33. When the abusive force on the car exceeds the preset threshold, the force transmitted by the first swing arm 10 causes the hook 317 that fixes the first slider 311 and the second slider 312 to disengage 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, allowing the first swing arm 10 to rotate freely from the first rotation position to the second rotation position to avoid causing harm to the human body.

[0076] In some embodiments of this application, see Figure 12 as well as Figure 16 , Figure 16A schematic diagram of a fixing component 32 in an embodiment of this application is shown. The fixing 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 mounted on the base plate 321. The drive shaft 323 has a lead screw portion 3231. A nut 316 is fixed to the moving component 31, and the nut 316 cooperates with the lead screw portion 3231. The drive shaft 323 is rotatably mounted on the base plate 321. 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 lead screw portion 3231 of the drive shaft 323, thereby driving the nut 316 and driving the moving component 31 to move. Finally, the moving component 31 moves relative to the base plate 321 in a preset direction and pulls the first swing arm 10 to move through the connecting rod 33.

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

[0078] It should be noted that, in combination Figure 14 As can be seen from the structure of link 33, during the reciprocating swing of the first swing arm 10 in a direction perpendicular to the first axis X, link 33 does not restrict the first swing arm 10 from reciprocating in the same direction. At this time, the first massage head 20 contacts the back of the human body in a left-right moving manner, so as to realize the kneading massage process of the human back. At the same time, since the second motor 322 can not only drive the moving component 31 to move along the preset direction, but also drive the first swing arm 10 to reciprocate around the direction perpendicular to the first axis X, it is beneficial to reduce the number of motors in the massage device 100, thereby reducing the cost of the massage device 100 and reducing the space occupied by the massage device 100 in the seat.

[0079] As an exemplary embodiment of the motor-driven first swing arm 10 reciprocating about a direction perpendicular to the first axis X, see [reference]. Figure 17 , Figure 17 An exploded view of a fixing component 32 in an embodiment of this application is shown. A turbine 325 is mounted on the second eccentric rotating shaft 324, and the drive shaft 323 also has a worm gear portion 3232. The turbine 325 and the worm gear portion 3232 cooperate. During the rotation of the drive shaft 323, the worm gear portion 3232 drives the turbine 325 to rotate, thereby causing the second eccentric rotating shaft 324 to rotate. Finally, the second eccentric rotating shaft 324 drives the first swing arm 10 to swing back and forth around the direction perpendicular to the first axis X.

[0080] In some embodiments of this application, see Figure 18 , Figure 18 This paper shows an exploded view of the connecting rod 33 and the first swing arm 10 in an embodiment of this application. The first swing arm 10 has a ball joint 101, and the second end of the connecting rod 33 has a ball head 3301. The ball head 3301 fits into the ball joint 101. That is, the connecting rod 33 is connected to the first swing arm 10 via the ball joint 3301 and the ball joint 101, forming a ball-joint connection. Figure 14 As can be seen from the structure of the connecting rod 33, the first swing arm 10 can not only rotate around the first axis X through the cooperation of the ball head 3301 and the ball socket 101, but also swing back and forth around the direction perpendicular to the first axis X.

[0081] In some embodiments of this application, see Figure 19 , Figure 19 The diagram shows a structural schematic of the connecting rod 33 and the first swing arm 10 in an embodiment of this application. The ball socket 101 passes through the first swing arm 10, and the second end of the connecting rod 33 passes through the ball socket 101 and is fitted with a second swing arm 40. The second swing arm 40 is fitted with a second massage head 50 at the end opposite to the first end of the connecting rod 33. In other words, more massage heads can be installed on the second swing arm 40 fixed by the connecting rod 33, so as to provide users with a richer massage experience through the first massage head 20 and the second massage head 50.

[0082] It is worth noting that the above description of the massage device 100 is intended to clearly illustrate the implementation and verification process of this application. Those skilled in the art can make equivalent modifications or further designs under the guidance of this application. For example, the second motor 322 can drive the second eccentric shaft 324 to rotate via a belt or other transmission mechanism; or, for example, see [reference to...]. Figure 16 A third motor 326 can also be installed on the base plate 321. The third motor 326 can 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.
