[0001] This application is based on and claims priority to Chinese Patent Application No. 202511810982.5, filed on December 3, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of automotive massage seat equipment technology, and more specifically, to a collapsible mechanism and a massage mechanism. Background Technology

[0003] With the rapid popularization of automobiles, people have higher requirements for their travel experience. Adding massage structures to car seats can effectively improve the user's travel experience and reduce fatigue during travel.

[0004] One type of car seat massager uses a mechanical structure to drive massage heads to perform various massage actions such as kneading. It provides a certain massage intensity, simulating a human hand massage and offering a relatively good user experience. However, in emergency situations, most mechanical massagers have issues with failure to collapse or slow collapse speed, which can easily cause harm to the human body. Furthermore, some existing collapse mechanisms are space-consuming and complex in design, resulting in high costs and hindering widespread adoption. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a collapsible mechanism for a massage mechanism, which not only can quickly generate a collapsible response in emergency situations, but also occupies little space and has controllable costs.

[0006] The present invention also aims to protect the massage mechanism of the aforementioned collapse mechanism.

[0007] The collapsible mechanism of the massage core according to an embodiment of the present invention includes: a support body, wherein the support body is provided with a first movable channel extending in a first direction, and the support body is further provided with a second movable channel communicating with the first movable channel; a collapsible pull rod, one end of which is located in the first movable channel and is provided with a locking hole, the collapsible pull rod being movable in the first direction; a locking pin, the locking pin being movably disposed in the second movable channel; and a collapsible spring, the collapsible spring being located in the second movable channel and connected to the locking pin, the collapsible spring being used to push the locking pin to extend toward the first movable channel to lock at the locking hole; when the collapsible pull rod is subjected to force and squeezes the locking pin, it can compress the collapsible spring and squeeze the locking pin into the second movable channel.

[0008] The collapsible mechanism of the massage core according to an embodiment of the present invention utilizes a mechanical structure to achieve an emergency judgment mechanism. If the impact force of a passenger hitting the massage core during normal use is small, the massage core will not harm the passenger, and it will not collapse. However, if the impact force is large, the massage core may harm the passenger, in which case it will collapse. This design ensures that the normal use of the massage core is not affected, while also allowing for a rapid response in emergency situations, enabling the massage arm to collapse freely and providing stronger protection for the human body.

[0009] Furthermore, in this application, when the collapsible tie rod is moved and reset in the first direction under force, the locking pin can remain locked in the locking hole of the collapsible tie rod again, and the collapsible tie rod maintains its position relative to the support body, making reset simple. This collapsible mechanism is small in size, has few parts, is simple to assemble, has low cost, and is convenient for widespread use.

[0010] In some embodiments, the locking pin is a ball, and the collapsible spring is a cylindrical spring.

[0011] Specifically, the locking pin is fixedly connected to the end of the collapsible spring.

[0012] In some embodiments, the second movable channel forms a threaded hole on the outer surface of the support; The collapsing mechanism further includes a threaded connector that fits into the threaded hole, and the end of the collapsing spring is connected to the threaded connector.

[0013] In some embodiments, the support body has two second movable channels arranged along a second direction and located on opposite sides of the first movable channel, and the second direction intersects the first direction; Each of the second movable channels is equipped with the collapsible spring and the locking pin, with the two locking pins locking onto both sides of the collapsible tie rod.

[0014] Specifically, the two second movable channels are located on the same straight line, and the first direction is perpendicular to the second direction; the locking hole on the collapsible tie rod is provided through the second direction.

[0015] According to an embodiment of the present invention, a massage mechanism includes: a base plate; a massage arm swayably disposed on the base plate; a collapsible mechanism of the massage mechanism described in the above embodiment, wherein the support body is mounted on the base plate; and an intensity adjustment assembly movably disposed on the base plate along a first direction, the intensity adjustment assembly including a universal joint, the universal joint being hinged to the massage arm to adjust the range of motion of the massage arm when moving along the first direction. The intensity adjustment component is connected to the collapse lever so that the massage arm swings and pulls the collapse lever through the intensity adjustment component when the arm is crushed by an impact.

[0016] Specifically, the intensity adjustment component includes: A movable stage, which is movably disposed on the substrate along the first direction; A strength adjustment drive is mounted on the moving platform, and the strength adjustment drive cooperates with the collapsible tie rod to drive the moving platform to move along the first direction; A movable shaft is disposed on the movable platform, and the universal joint is mounted on the movable shaft; Specifically, the strength adjustment drive stops during a collision and crushing event to remain fixed to the crushing tie rod.

[0017] According to this invention, the massage mechanism utilizes the synchronized movement of the intensity adjustment component and the collapsible lever during collapse, connecting the two. During normal use, the collapsible lever is engaged, ensuring the movement of the intensity adjustment component is not affected while keeping the lever stationary. In emergencies, by overcoming the elastic force of the collapse spring, the collapsible lever and intensity adjustment component can move freely along the first direction X, allowing the massage arm to unfold freely and preventing secondary impact injuries to the user. Furthermore, the connection between the intensity adjustment component and the collapsible lever also allows the component to reset the lever.

[0018] The collapsible mechanism is small in size, which makes it easier to thin the massage mechanism, facilitates assembly, and controls costs.

[0019] Furthermore, a limiting stage is provided on the substrate, and the limiting stage and the support are located on both sides of the strength adjustment drive member; When the collision occurs, the moving platform or the strength adjustment drive unit abuts against the limiting platform, and the collapse pull rod is reset and engaged with the locking pin under the drive of the strength adjustment drive unit.

[0020] Optionally, the strength adjustment drive is a reversible strength adjustment motor, and the collapsible pull rod is a lead screw.

[0021] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] The following is for reference. Figures 1-6 The collapse mechanism 10 of the massage mechanism 100 according to an embodiment of the present invention is described.

[0027] The massage mechanism 100 is installed on the massage chair and is the core component for realizing the massage function. The massage chair can be installed in any means of transportation such as cars and airplanes, so that users can receive massage services through the massage mechanism 100 while riding in the massage chair, thereby effectively improving the user's travel experience. Furthermore, in the event of an emergency, such as sudden braking or a collision, the massage mechanism 10 can release impact energy using the collapse mechanism 10, allowing the massage arm 30 to collapse rapidly, thereby preventing secondary injury to the human body.

[0028] The collapsing mechanism 10 of the massage mechanism 100 according to an embodiment of the present invention, with reference to Figures 1-3 It includes: a support body 11, a collapsible tie rod 12, a locking pin 13, and a collapsible spring 14.

[0029] The support body 11 has a first movable channel P1 extending along a first direction X, and a second movable channel P2 communicating with the first movable channel P1 is also provided inside the support body 11. One end of the collapsible pull rod 12 is located in the first movable channel P1 and has a locking hole 121, and the collapsible pull rod 12 is movable along the first direction X. The locking pin 13 is movably disposed in the second movable channel P2. The collapsible spring 14 is located in the second movable channel P2 and connected to the locking pin 13. The collapsible spring 14 is used to push the locking pin 13 toward the first movable channel P1 to lock in the locking hole 121. When the collapsible pull rod 12 is subjected to force and presses the locking pin 13, it can compress the collapsible spring 14 and squeeze the locking pin 13 into the second movable channel P2.

[0030] Thus, during normal use of the massage mechanism 100, the elastic force of the collapsible spring 14 acting on the locking pin 13 keeps the locking pin 13 in the locking hole 121 of the collapsible pull rod 12, keeping the collapsible pull rod 12 in a fixed position relative to the support body 11. Figure 4 As shown, the collapsible lever 12 is equivalent to a fixing element, and the collapsible lever 12 has a limiting effect on the massage arm 30.

[0031] In the event of an emergency such as sudden braking or collision, where a passenger may collide with the massage mechanism 100 due to sudden braking or vehicle collision, or a passenger may fall down while playing and collide with the massage mechanism 100, a large impact force is generated due to the collision. The impact force is transmitted to the collapsible lever 12, causing the collapsible lever 12 to be subjected to force in the first direction X, thereby causing the collapsible lever 12 to squeeze the locking pin 13.

[0032] When the compressive force of the collapsible lever 12 on the locking pin 13 overcomes the elastic force of the collapsible spring 14, the collapsible spring 14 contracts, thereby causing the locking pin 13 to retract into the second movable channel P2. At this time, as... Figure 5 As shown, without the constraint of the locking pin 13 on the collapsible lever 12, it can move freely in the first direction X. In this way, the restrictive effect of the collapsible lever 12 on the massage arm 30 is removed, allowing the massage arm 30 to collapse freely.

[0033] In other words, in this application, the locking pin 13 and the collapsible spring 14 work together to limit the impact force on the massage mechanism 100, ensuring that the locking pin 13 can always hold the collapsible lever 12 in place, preventing the massage arm 30 from collapsing freely, when the impact force on the massage mechanism 100 exceeds the threshold. Only when the impact force on the massage mechanism 100 exceeds the threshold, causing the pressure of the collapsible lever 12 on the locking pin 13 to exceed the elastic force of the collapsible spring 14, can the locking pin 13 release the collapsible lever 12, allowing the massage arm 30 to collapse freely.

[0034] This application utilizes a mechanical structure to achieve an emergency judgment mechanism. If the impact force of a passenger hitting the massage mechanism 100 during normal use is small, the massage mechanism 100 will not injure the passenger, and will not collapse. However, if the impact force of a passenger hitting the massage mechanism 100 is large, the massage mechanism 100 may injure the passenger, in which case it will collapse.

[0035] Compared to relying solely on a spring as a collapse mechanism, according to Hooke's Law, the massage mechanism will always collapse to some extent upon impact, which will affect its normal operation. Furthermore, when the impact force is large, the pressure on the spring is high, and the reaction force released by the spring is also large, which still significantly restricts the massage mechanism, making it inconvenient to use. In contrast, the solution in this application allows the massage arm 30 to collapse freely once the impact force exceeds a threshold, providing stronger protection for the user. Additionally, when the collapse lever 12 is moved and reset along the first direction X under force, the locking pin 13 can remain locked in the locking hole 121 of the collapse lever 12, and the collapse lever 12 maintains its position relative to the support body 11. Therefore, reset is simple.

[0036] This type of collapse mechanism 10 is small in size, has few parts, is simple to assemble, has low cost, and is easy to use.

[0037] In some embodiments, such as Figure 2 and Figure 3 As shown, the locking pin 13 is a sphere. When the sphere moves and generates friction with the support body 11 and the collapsible tie rod 12, the locking pin 13 can roll to offset the friction and avoid the locking pin 13 from being misaligned and stuck.

[0038] Of course, the solution proposed in this application is not limited to this. For example, the locking pin 13 can also be a column, and the end face of the locking pin 13 facing the first movable channel P1 is spherical or conical. In this way, when the collapsible tie rod 12 is pressed by the locking pin 13, the force can be easily transmitted to the collapsible spring 14 through the locking pin 13, so that the collapsible spring 14 can contract.

[0039] Optionally, pin 13 can be a steel ball.

[0040] Specifically, the collapsible spring 14 is a cylindrical spring. Optionally, the outer diameter of the cylindrical spring is approximately equal to the diameter of the second movable channel P2. This arrangement facilitates the use of the inner wall of the second movable channel P2 to guide the extension and retraction of the collapsible spring 14, preventing the collapsible spring 14 from becoming misaligned and failing.

[0041] Specifically, such as Figure 2As shown, the locking pin 13 is fixedly connected to the end of the collapsible spring 14. This helps to fix at least a portion of the locking pin 13 in the second movable channel P2, preventing the locking pin 13 from falling entirely into the first movable channel P1 after the collapsible pull rod 12 is removed, and preventing the locking pin 13 from blocking the collapsible pull rod 12 from resetting.

[0042] In some alternative embodiments, when the end of the collapsible spring 14 is fitted onto the retaining pin 13, the two can be fixed together by welding or adhesive. In other alternative embodiments, the retaining pin 13 has a groove on its outer periphery, and the end of the collapsible spring 14 is clamped in the groove.

[0043] In the above embodiment, the locking pin 13 is fixedly connected to the end of the collapsible spring 14, preventing the locking pin 13 from detaching from the collapsible spring 14 and falling into the first movable channel P1. Specifically, the second movable channel P2 is a straight circular channel, which is convenient for processing.

[0044] In some alternative embodiments, the port of the second movable channel P2 facing the first movable channel P1 is an inner through-hole 111. The inner through-hole 111 can be set as a narrow opening. After narrowing, the minimum diameter of the inner through-hole 111 is smaller than the maximum diameter of the locking pin 13. In this way, most of the locking pin 13 can be locked in the second movable channel P2.

[0045] In some specific embodiments, the second movable channel P2 forms a threaded hole 112 on the outer surface of the support 11. For example... Figure 2 As shown, the collapse mechanism 10 also includes a threaded connector 15, which fits into the threaded hole 112, and the end of the collapse spring 14 is connected to the threaded connector 15.

[0046] The threaded connector 15 allows the retaining pin 13 and the collapsible spring 14 to be inserted into the second movable channel P2 through the threaded hole 112 after the threaded connector 15 is removed, improving assembly convenience. The compression of the collapsible spring 14 can be adjusted by tightening or loosening the threaded connector 15, thereby adjusting the clamping force of the collapsible spring 14 on the retaining pin 13. This adjusts the threshold of impact force experienced by the massage mechanism 100 when the collapsible pull rod 12 moves from its normal operating state to its free collapsible state. This achieves adjustable collapsible force of the collapsible mechanism 10.

[0047] Specifically, a groove is formed on the side of the threaded connector 15 facing the first movable channel P1, and the end of the collapsible spring 14 is located in the groove. This facilitates positioning and fixation, and avoids excessive contact wear between the collapsible spring 14 and the thread when the threaded connector 15 is threadedly connected to the threaded hole 112.

[0048] Of course, the proposed solution is not limited to this. For example, the threaded connector 15 can be directly replaced with a plug, which is fixed by an interference fit.

[0049] In some specific embodiments, such as Figure 2 As shown, the support body 11 has two second movable channels P2 arranged along the second direction Y, and located on opposite sides of the first movable channel P1. The second direction Y intersects the first direction X.

[0050] Each of the second movable channels P2 is equipped with a collapsible spring 14 and a locking pin 13, with the two locking pins 13 securing them to both sides of the collapsible tie rod 12. This ensures that the force on both sides of the collapsible tie rod 12 is relatively balanced, reducing the likelihood of jamming and increasing reliability.

[0051] Specifically, the two second movable channels P2 are located on the same straight line, with the first direction X and the second direction Y perpendicular to each other. The locking hole 121 on the collapsible tie rod 12 is provided through the second direction Y. This arrangement allows for the use of a single drill bit to drill the two opposing second movable channels P2 in one operation, further facilitating machining.

[0052] In some designs, an acute angle is formed between the first direction X and the second direction Y, for example, the angle between the first direction X and the second direction Y is 60 degrees, 70 degrees, 80 degrees, etc.

[0053] Optionally, the collapsible tie rod 12 has a locking hole 121 that extends and passes through along the second direction Y, and two locking pins 13 are locked at both ends of the same locking hole 121, which also facilitates processing.

[0054] In summary, this collapse mechanism 10 has a simple structure, occupies a small volume, has high reliability, is easy to arrange on the massage mechanism 100, facilitates the control of the thickness of the massage mechanism 100, and helps to keep the massage mechanism 100 as a whole relatively thin.

[0055] The massage mechanism 100 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0056] The massage mechanism 100 according to an embodiment of the present invention, such as Figure 6 As shown, it includes: a base plate 20, a massage arm 30, a collapsing mechanism 10 of the massage core 100 in the above embodiment, and an intensity adjustment component 40. The structure of the collapsing mechanism 10 will not be described in detail here.

[0057] The massage arm 30 is oscillatingly mounted on the base plate 20. Specifically, the massage arm 30 is provided with a massage head 31. When the massage arm 30 oscillates, the massage head 31 acts on the human body part to produce a pressing effect.

[0058] The intensity adjustment component 40 is movably mounted on the base plate 20 along the first direction X. The intensity adjustment component 40 includes a universal joint 41, which is hinged to the massage arm 30 to adjust the range of motion of the massage arm 30 when moving along the first direction X. That is, the massage arm 30 is restrained by the universal joint 41 when it swings. Although the massage arm 30 can swing to produce a pressing action, the amplitude of the swing of the massage arm 30 varies when the intensity adjustment component 40 moves to different positions along the first direction X, thus producing different pressing intensities. The principle of amplitude adjustment of the massage arm 30 by the intensity adjustment component 40 is prior art and will not be elaborated here.

[0059] In this application, the support 11 is mounted on the substrate 20, and the strength adjustment component 40 is connected to the collapse lever 12 so that the massage arm 30 swings and pulls the collapse lever 12 through the strength adjustment component 40 when it is crushed by impact.

[0060] Thus, during normal use of the massage mechanism 100, the elastic force of the collapsible spring 14 acting on the locking pin 13 keeps the locking pin 13 locked in the locking hole 121 of the collapsible pull rod 12, so that the position of the collapsible pull rod 12 relative to the support body 11 and the base plate 20 remains unchanged. At this time, when the intensity adjustment component 40 needs to adjust the massage amplitude of the massage arm 30, it can move along the first direction X. Since the collapsible pull rod 12 is locked, it does not affect the operation of the intensity adjustment component 40, and it can keep the collapsible pull rod 12 stationary.

[0061] In an emergency, if a person collides with the massage mechanism 100, especially with the massage arm 30, the massage arm 30 will swing and unfold under the force. The unfolding motion of the massage arm 30 is also its collapsing motion, to avoid secondary impact on the body.

[0062] The impact force on the massage arm 30 is transmitted to the intensity adjustment component 40, which pushes the intensity adjustment component 40 to move along the first direction X. The impact force is transmitted to the collapsible pull rod 12, causing the collapsible pull rod 12 to be subjected to force along the first direction X, thereby causing the collapsible pull rod 12 to squeeze the locking pin 13.

[0063] When the compressive force of the collapsible lever 12 on the locking pin 13 overcomes the elastic force of the collapsible spring 14, the collapsible spring 14 contracts, causing the locking pin 13 to retract into the second movable channel P2. Without the constraint of the locking pin 13, the collapsible lever 12 can move freely along the first direction X. Thus, the intensity adjustment assembly 40 can move freely along the first direction X, causing the massage arm 30 to unfold freely.

[0064] Furthermore, when a reset is required after an emergency, the strength adjustment component 40 can reset along the first direction X, thereby driving the collapsible lever 12 to reset, achieving automatic reset.

[0065] According to the massage mechanism 100 of the present invention, the intensity adjustment component 40 and the collapsible pull rod 12 are connected by their synchronized movements during collapse. During normal use, the collapsible pull rod 12 is held in place, ensuring that the movement of the intensity adjustment component 40 is not affected, while also keeping the pull rod 12 stationary. In an emergency, the elastic force of the collapse spring 14 is overcome, allowing the collapsible pull rod 12 and the intensity adjustment component 40 to move freely along the first direction X, enabling the massage arm 30 to unfold freely and preventing secondary impact injuries to the human body. Furthermore, the connection between the intensity adjustment component 40 and the collapsible pull rod 12 also allows the intensity adjustment component 40 to reset the collapsible pull rod 12.

[0066] The collapsible mechanism 10 is small in size, which makes it easier to thin the massage mechanism 100, facilitates assembly, and controls costs.

[0067] In some specific embodiments, such as Figure 6 As shown, the intensity adjustment assembly 40 includes a movable stage 42, an intensity adjustment drive 43, and a movable shaft 44. The movable stage 42 is movably mounted on the base plate 20 along a first direction X. The intensity adjustment drive 43 is mounted on the movable stage 42 and cooperates with the collapsible tie rod 12 to drive the movable stage 42 to move along the first direction X. The movable shaft 44 is mounted on the movable stage 42, and a universal joint 41 is mounted on the movable shaft 44.

[0068] In the event of a collision and crushing, the strength adjustment drive 43 stops to remain fixed to the crushing tie rod 12.

[0069] This is equivalent to incorporating a linear motion drive structure into the collapsible tie rod 12, which reduces the number of parts and further reduces the space occupied. Moreover, the collapsible tie rod 12 can also serve as a guide and limiting structure to keep the moving stage 42 moving linearly along the first direction X.

[0070] Here, the strength adjustment drive 43 cooperates with the collapsible tie rod 12 to drive the moving platform 42 to move along the first direction X in various structural forms.

[0071] For example, a turbine is provided on the strength adjustment drive component 43, and a worm gear is formed on the collapsible tie rod 12. The worm gear extends along the first direction X, and the turbine cooperates with the worm gear. In this way, the strength adjustment drive component 43 drives the turbine to rotate, thereby enabling the strength adjustment drive component 43 to move linearly relative to the worm gear along the first direction X.

[0072] For example, the strength adjustment drive 43 is equipped with a gear, and the collapsible tie rod 12 is formed with a rack extending along the first direction X. The gear meshes with the rack. In this way, the strength adjustment drive 43 drives the gear to rotate, thereby allowing the strength adjustment drive 43 to move linearly relative to the rack along the first direction X.

[0073] For example, the strength adjustment drive 43 is equipped with a drive nut, and the collapsible pull rod 12 is a lead screw, with the drive nut threaded into the lead screw. In this way, the strength adjustment drive 43 drives the drive nut, thereby allowing the strength adjustment drive 43 to move linearly relative to the collapsible pull rod 12 in the first direction X.

[0074] In the above embodiment, the intensity adjustment drive 43 can be a forward and reverse intensity adjustment motor, so that during normal use, the intensity adjustment drive 43 can rotate in both directions. In both rotation directions, the intensity adjustment assembly 40 can move bidirectionally on the base plate 20, thus allowing for flexible adjustment of the position of the universal joint 41.

[0075] It is also possible that in some embodiments, the intensity adjustment drive 43 is a linear actuator, and the collapsible lever 12 can be connected to the actuator shaft of the linear actuator. In this way, during normal use, the collapsible lever 12 can be used as a fixing component, and the linear actuator can pull the entire intensity adjustment assembly 40 to move along the first direction X.

[0076] In the above scheme, the strength adjustment drive 43 and the collapse lever 12 are in a dynamic cooperation relationship. When the arm is crushed by a collision, the strength adjustment drive 43 stops, and the cooperation between the two generates a large frictional force, which keeps the strength adjustment component 40 and the collapse lever 12 fixed. In this way, when the massage arm 30 is subjected to a large impact force, it can be transmitted to the collapse lever 12 through the strength adjustment component 40, ensuring that the collapse mechanism 10 acts in a timely and rapid manner.

[0077] In some specific embodiments, such as Figure 6 As shown, a limiting stage 21 is provided on the substrate 20, and the limiting stage 21 and the support body 11 are located on both sides of the strength adjustment drive member 43.

[0078] When the collision occurs, the moving platform 42 or the strength adjustment drive 43 abuts against the limiting platform 21, and the collapse pull rod 12 is reset and engages with the locking pin 13 under the drive of the strength adjustment drive 43.

[0079] The upper limit stage 21 on the substrate 20 constrains the movement range of the strength adjustment drive 43. When a reset is required, since the collapsible lever 12 is in a free-moving state, the strength adjustment drive 43 can apply force to the limiting stage 21 when it is activated. Under the reaction force of the limiting stage 21, the strength adjustment drive 43 can push the collapsible lever 12 to move, thereby causing the collapsible lever 12 to reset and engage with the locking pin 13.

[0080] Once the collapsible lever 12 is reset, it can once again function as a fixing element. The strength adjustment drive 43 can adjust the position of the entire strength adjustment assembly 40 by pulling the collapsible lever 12, thereby adjusting the swing amplitude of the massage arm 30.

[0081] Other components of the massage mechanism 100 according to embodiments of the present invention, such as kneading motors and walking drive motors, are known to those skilled in the art in terms of their working principles and operation, and will not be described in detail here.
