Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a magnetic levitation guide rail for a rhythmic motion core, a magnetic levitation rhythmic motion core, and rhythmic furniture. Background Technology

[0002] Various massage chairs, massage sofa beds, and other furniture and equipment on the market incorporate a rhythmic core. This core consists of a fixed base and a rhythmic support. A combination of coils and magnets is used between the fixed base and the rhythmic support. Electromagnetic force is used to stably suspend the rhythmic support above the fixed base, thereby achieving the rhythmic function.

[0003] However, this technical design has a problem: when the device experiences a power outage, the electromagnetic force that maintains its levitation state disappears instantly, and the rhythmic support falls directly due to the loss of power support, inevitably causing rigid contact and friction between the magnet and the coil; if the impact force is too great, it may even cause a violent collision between the rhythmic support and the fixed base. This abnormal mechanical contact not only accelerates the wear of core components inside the mechanism (such as coils and magnets), but also significantly shortens the lifespan of the rhythmic mechanism. In severe cases, it may also cause problems such as abnormal noise and functional failure, greatly affecting the reliability of the product and the user experience. At the same time, the coil material is expensive.

[0004] In addition to the above, the magnetic levitation guide rail has a complex structure and high cost due to the use of coils and magnets on the side to restrict displacement in the left and right directions. In addition, in the vertical direction, the force on the rhythm device is different when it is unloaded and fully loaded. Since there is no limit to the vertical movement range of the magnetic levitation, the vertical movement gap is too large. For example, during the high-frequency vibration of the rhythm chair, the uneven force on the front and back and the inertia of the reversal will cause the two ends of the rhythm chair to tilt up and down, making it impossible for the rhythm chair to maintain horizontal movement. Utility Model Content

[0005] This utility model provides a magnetic levitation guide rail for a beater core, which solves the problem in related technologies that beater cores rely on electromagnetic force to achieve levitation. When the power is off, the disappearance of electromagnetic force can easily lead to direct contact and friction between the magnet and the coil, or even collision with the fixed base, causing damage to the components and shortening their service life. It also solves the problems of high cost, complex structure, and large up-and-down tilt at both ends of the electromagnetic guide rail.

[0006] This utility model provides a magnetic levitation guide rail for a beater motor core, comprising:

[0007] The first guide rail seat is used to connect the fixed base of the beater core;

[0008] The second guide rail seat is used to connect the rhythm bracket of the rhythm motor core, and the second guide rail seat is movably connected to the first guide rail seat. The first guide rail seat is provided with a first hook part, and the second guide rail seat is provided with a second hook part. The first hook part and the second hook part are hooked and connected vertically.

[0009] A magnetic structure includes a first magnet and a second magnet, wherein the first magnet is disposed on the first guide rail seat and the second magnet is disposed on the second guide rail seat;

[0010] The first guide rail and the second guide rail have a suspension gap in the vertical direction. The first magnet and the second magnet repel each other magnetically to form a magnetic levitation force. The magnetic levitation force is used to drive the second guide rail to levitate on the first guide rail.

[0011] The first hook portion and the second hook portion are provided with a flexible structure for elastic limiting. The flexible structure is used to cooperate with the first magnet and the second magnet to limit the movement of the second guide rail seat along the length direction of the first guide rail seat.

[0012] According to the present invention, a magnetic levitation guide rail for a beater core is provided, which further includes a gap adjustment structure, wherein the gap adjustment structure is disposed in at least one of the first guide rail seat and the second guide rail seat;

[0013] The gap adjustment structure is used to drive at least one of the first magnet and the second magnet to move in the up-down direction to adjust the suspension gap.

[0014] According to the present invention, a magnetic levitation guide rail for a beater core is provided, wherein the gap adjustment structure includes:

[0015] An adjusting plate is provided on the first guide rail seat, which can be moved up and down;

[0016] An adjustment unit is mounted on the first guide rail seat and is in transmission cooperation with the adjustment plate.

[0017] The first magnet is disposed on the adjustment plate.

[0018] According to the present invention, a magnetic levitation guide rail for a beater core is provided, wherein the adjustment unit includes an adjustment bolt threadedly connected to the first guide rail seat and a limiting nut threadedly connected to the adjustment bolt.

[0019] According to the present invention, a magnetic levitation guide rail for a beater core is provided, wherein the flexible structure is a rubber ball.

[0020] According to the present invention, a magnetic levitation guide rail for a beater core is provided, wherein the flexible structure comprises multiple components.

[0021] According to the present invention, a magnetic levitation guide rail for a rhythmic motor core is provided, wherein the left and right side walls of the first guide rail seat are respectively provided with a first hook part, and the left and right side walls of the second guide rail seat are respectively provided with a second hook part.

[0022] According to the present invention, a magnetic levitation guide rail for a beater core is provided, wherein the cross-sectional shape of the first hook part and the second hook part is arc-shaped.

[0023] This utility model also provides a magnetic levitation rhythm core, comprising:

[0024] Fixed base frame;

[0025] A rhythmic support frame, which is movable back and forth relative to the fixed base frame;

[0026] The magnetic levitation guide rail described above for the rhythmic motor core has the first guide rail seat fixedly connected to the fixed base frame, and the second guide rail seat fixedly connected to the rhythmic support frame.

[0027] This utility model also provides a rhythmic furniture, including the above-mentioned magnetic levitation rhythmic motor core.

[0028] The magnetic levitation guide rail provided by this utility model has a first magnet and a second magnet that repel each other between the first guide rail seat and the second guide rail seat. The magnetic levitation force generated by the repulsion of permanent magnets makes the second guide rail seat levitate on the first guide rail seat, maintaining a levitation gap. This replaces the reliance on electromagnetic force. In this way, even if there is a power outage, the magnetic levitation force can still maintain the levitation state, avoiding direct contact, friction and impact between the second guide rail seat and the fixed base or the first guide rail seat. This helps to avoid violent collisions between the rhythmic bracket and the fixed base, reduce component wear, extend service life, and improve operational stability.

[0029] By using a first and a second magnet to suspend the device vertically, and combining this with a flexible structure such as a rubber ball to restrict lateral movement, a suspension system is formed. This system allows the guide rail to be suspended by the magnets without friction. At the same time, because the lateral force is relatively small, the friction force on the flexible structure such as the rubber ball is small, resulting in a longer lifespan. The frictionless suspension of the magnets also extends the overall lifespan of the device. This achieves the effect of magnetic levitation, while also being simple in structure, low in cost, and quiet during high-frequency back-and-forth vibration.

[0030] At the same time, the gap adjustment structure is used to adjust the distance between the two first magnets and the second magnet, so that the two magnets maintain a certain pressure. When a person sits on it, the gap between the first magnet and the second magnet does not change much. In addition, the flexible structure, such as the rubber ball, has a certain elasticity to compensate for the gap, so it can reduce noise and alleviate the problem of front and back tilting. Furthermore, the gap between the two magnets does not need to be considered during installation. The distance between the two magnets can be larger during installation, which is easy to install and has a low risk factor. The gap can be adjusted after installation. Attached Figure Description

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] The following is combined Figures 1-5 This invention describes a magnetic levitation guide rail 400 for a rhythmic motion core, a magnetic levitation motion core, and rhythmic furniture. The rhythmic furniture includes the aforementioned magnetic levitation motion core and a supporting body. The reciprocating motion of the magnetic levitation motion core drives the supporting body to move laterally back and forth. It is understood that the aforementioned rhythmic furniture can be a rhythmic chair, a rhythmic bed, etc. In this embodiment of the invention, the rhythmic furniture is a rhythmic chair.

[0044] Understandably, referring to Figure 1 , Figures 3 to 5 In some examples of this utility model, the magnetic levitation rhythm motor core includes a fixed base frame 100, a rhythm support 200, a magnetic levitation guide rail 400, and a drive mechanism 300. The rhythm support 200 can move back and forth relative to the fixed base frame 100.

[0045] The drive mechanism 300 is mounted on the fixed base frame 100. The power output end of the drive mechanism 300 is connected to the rhythm bracket 200 to drive the rhythm bracket 200 to move back and forth relative to the fixed base frame 100.

[0046] Reference Figure 1 , Figures 3 to 5 In some examples of this utility model, the magnetic levitation guide rail 400 for the rhythmic motor core includes a first guide rail seat 410 and a second guide rail seat 420. The first guide rail seat 410 is used to connect the fixed base frame 100 of the rhythmic motor core; the second guide rail seat 420 is used to connect the rhythmic support 200 of the rhythmic motor core, and the second guide rail seat 420 and the first guide rail seat 410 are movably connected back and forth; the magnetic structure includes a first magnet 411 and a second magnet 421, the first magnet 411 is disposed on the first guide rail seat 410, and the second magnet 421 is disposed on the second guide rail seat 420.

[0047] The first guide rail seat 410 and the second guide rail seat 420 have a suspension gap in the vertical direction. The first magnet 411 and the second magnet 421 repel each other magnetically to form a magnetic levitation force. The magnetic levitation force is used to drive the second guide rail seat 420 to levitate on the first guide rail seat 410.

[0048] A first magnet 411 and a second magnet 421 that repel each other are provided between the first guide rail seat 410 and the second guide rail seat 420. The magnetic levitation force generated by the repulsion of permanent magnets makes the second guide rail seat 420 levitate on the first guide rail seat 410, maintaining a levitation gap. This replaces the reliance on electromagnetic force. In this way, even if there is a power outage, the magnetic levitation force can still maintain the levitation state, avoiding direct contact, friction and impact between the second guide rail seat 420 and the fixed base frame 100 or the first guide rail seat 410. This helps to avoid violent collisions between the rhythmic bracket 200 and the fixed base frame 100, reduce component wear, extend service life, and improve operational stability.

[0049] Reference Figure 1 In some embodiments of this utility model, the magnetic levitation guide rails 400 are in multiple sets, respectively disposed between the left and right sides of the fixed base frame 100 and the rhythmic support 200. Of course, the number of magnetic levitation guide rails 400 can be selected according to the specific structural design, and is not limited here.

[0050] Understandably, referring to Figures 3 to 5 In some examples of this utility model, the first guide rail seat 410 is provided with a first hook part 413, and the second guide rail seat 420 is provided with a second hook part 422. The first hook part 413 and the second hook part 422 are hooked and connected vertically.

[0051] Among them, a flexible structure 430 is provided between the first hook part 413 and the second hook part 422. The flexible structure 430 is used to cooperate with the first magnet 411 and the second magnet 421 to limit the movement of the second guide rail seat 420 along the length direction of the first guide rail seat 410, that is, the front-back direction.

[0052] It should be noted that in this embodiment, the flexible structure 430430 is a rubber ball. By combining the rubber ball with magnetic levitation, it is possible to achieve vertical levitation at a low cost, and simultaneously achieve lateral rhythmic guidance at a low cost. This combination ensures simple installation, low cost, high stability, and low precision requirements.

[0053] Of course, in some examples, the flexible structure 430 can also be a silicone ball, etc., and this is not limited here.

[0054] By using the first magnet 411 and the second magnet 421 to suspend vertically, and combining them with the flexible structure 430, such as a rubber ball, to restrict lateral movement, a suspension system is formed. This makes the guide rail frictionless due to the magnetic suspension. At the same time, because the lateral force is relatively small, the friction force on the flexible structure 430, such as the rubber ball, is small, resulting in a longer lifespan. In addition, the frictionless magnetic suspension extends the overall lifespan of the equipment. This achieves the effect of magnetic levitation, while also being simple in structure, low in cost, and quiet during high-frequency back-and-forth vibration.

[0055] Understandably, referring to Figure 4 In some examples of this utility model, there are multiple flexible structures 430 to enhance the overall stability of operation.

[0056] Reference Figure 4 In some examples of this utility model, flexible structures 430 are respectively provided on the opposite sides in the left-right direction between the first guide rail seat 410 and the second guide rail seat 420, which further enhances the overall stability of operation.

[0057] Specifically, refer to Figure 4 In this embodiment, the left and right side walls of the first guide rail seat 410 are respectively provided with a first hook part 413, and the left and right side walls of the second guide rail seat 420 are respectively provided with a second hook part 422. The first hook part 413 and the second hook part 422 are arranged in a one-to-one correspondence.

[0058] With the above configuration, the hooks on both sides of the first guide rail seat 410 and the second guide rail seat 420 form a symmetrical structure, so that multiple flexible structures 430 (such as rubber balls) are distributed on both sides of the guide rail seat for left and right guidance and positioning, avoiding deviation or tilting caused by unilateral force, and enhancing the overall stability of operation.

[0059] Reference Figures 3 to 5 In this embodiment, the first hook part 413 is a first arc-shaped groove arranged along the length direction of the first guide rail seat 410, and the second hook part 422 is a second arc-shaped groove arranged along the length direction of the second guide rail seat 420.

[0060] The curved surface structure of the arc groove can better fit the deformation characteristics of the flexible structure 430, so that the flexible structure 430 is compressed evenly along the arc surface when under pressure, thereby improving the stability of the buffer performance; it facilitates the installation and positioning of the flexible structure 430, while reducing the risk of loosening or misalignment after long-term use and extending the maintenance cycle.

[0061] Specifically, refer to Figures 3 to 5 In this embodiment, the cross-sectional shape of the first hook part 413 and the second hook part 422 is arc-shaped. The arc shape allows the flexible structure 430 to deform naturally along the curved surface when under pressure, providing a smoother buffering effect, reducing vibration transmission, and improving operational stability. It is easy to process and position the flexible structure 430, ensuring that the flexible structure 430 is automatically aligned during installation, reducing assembly errors, and facilitating later inspection or replacement.

[0062] Understandably, referring to Figures 3 to 5In some examples of this utility model, the magnetic levitation guide rail 400 further includes a gap adjustment structure 440, which is disposed on at least one of the first guide rail seat 410 and the second guide rail seat 420; the gap adjustment structure 440 is used to drive at least one of the first magnet 411 and the second magnet 421 to move in the up and down direction to adjust the levitation gap.

[0063] Understandably, assuming the magnetic levitation rail 400 lacks the gap adjustment structure 440, maintaining a small vertical movement gap would be extremely difficult and inefficient during installation due to the large repulsive force generated by the small gap between the two magnets, resulting in a high risk factor. However, this invention utilizes the gap adjustment structure 440 to adjust the distance between the two first magnets 411 and the second magnet 421, maintaining a certain pressure between them. When a person sits on the rail, the gap between the first magnet 411 and the second magnet 421 does not change significantly. Furthermore, the flexible structure 430, such as a rubber ball, provides elasticity to compensate for the gap, thus reducing noise and mitigating the front-to-back tilting issue. Additionally, the gap between the two magnets does not need to be considered during installation, allowing for a larger initial distance, making installation easier and less dangerous. Adjusting the gap after installation is simple, ensuring the upper and lower magnets move within a relatively small range.

[0064] Specifically, refer to Figures 3 to 5 In some examples of this utility model, the first magnet 411 is movably mounted on the first guide rail 410. The first guide rail 410 is provided with a gap adjustment structure 440. The gap adjustment structure 440 is connected to the first magnet 411 in a transmission manner to drive the first magnet 411 to move closer to or further away from the second magnet 421 to adjust the suspension gap.

[0065] By setting up a first magnet 411 that can move up and down and a matching gap adjustment structure 440, the active adjustment of the suspension gap between the first magnet 411 and the second magnet 421 is realized. On the one hand, the gap size can be dynamically adjusted according to load changes or working conditions, so that the magnetic levitation force is kept within a reasonable range (avoiding insufficient magnetic force due to excessive gap or accidental collision caused by excessive gap), and improving suspension stability. On the other hand, it can compensate for component wear or deformation caused by long-term use, maintain the suspension performance of the initial design, reduce the risk of abnormal friction caused by gap deviation, further extend the service life of the guide rail system, and enhance the adaptability to different operating scenarios.

[0066] Of course, in some examples, the gap adjustment structure 440 is provided on the second guide rail seat 420, or the gap adjustment structure 440 is provided on both the first guide rail seat 410 and the second guide rail seat 420.

[0067] In some examples, the gap adjustment structure 440 includes an adjustment plate 441 and an adjustment unit 442. The adjustment plate 441 is movably mounted on the first guide rail seat 410, and the adjustment unit 442 passes through the first guide rail seat 410 and is in transmission cooperation with the adjustment plate 441. The first magnet 411 is mounted on the adjustment plate 441.

[0068] It should be noted that the first magnet 411 can be fixedly connected to the adjustment plate 441 by means of bolt connection, snap-fit, or integral molding.

[0069] The gap adjustment structure 440 achieves flexible gap adjustment through the transmission cooperation between the adjustable plate 441, which can move up and down, and the adjustment unit 442; combined with the first magnet 411 on the adjustable plate 441, it improves the positioning stability during the adjustment process. The overall structure simplifies the gap adjustment operation and takes into account both adjustment accuracy and reliability.

[0070] It should be noted that, in this embodiment, the adjustment unit 442 includes an adjustment bolt 4421 threadedly connected to the first guide rail seat 410 and a limiting nut 4422 threadedly connected to the adjustment bolt 4421.

[0071] The limiting nut 4422 abuts against the first guide rail seat 410, limiting the up and down position of the adjusting plate 441. When it is necessary to adjust the up and down position of the adjusting plate 441, the limiting nut 4422 can be loosened. While ensuring the adjustment accuracy, the locking reliability is significantly improved.

[0072] Of course, in some examples, the adjustment unit 442 can also be a wedge self-locking mechanism. For example, the adjustment unit 442 is a wedge, one end of which contacts the adjustment plate 441 and the other end is connected to the rotating handle. The rotating handle pushes the wedge into the space between the first guide rail seat 410 and the adjustment plate 441, and the height is fixed by the mechanical self-locking of the inclined surface. This is not limited here.

[0073] Reference Figures 3 to 5 In some embodiments of this utility model, the first guide rail seat 410 is provided with a cavity 412, the second guide rail seat 420 is at least partially located in the cavity 412, and the adjusting plate 441 and the first magnet 411 are both located in the cavity 412.

[0074] The first guide rail seat 410 forms a closed space through the chamber 412, which partially houses the second guide rail seat 420 and also accommodates the adjustment plate 441 and the first magnet 411. The spatial limiting function of the chamber 412 can constrain the movement trajectory of the second guide rail seat 420, prevent it from interfering with the outside, and improve the straightness of the adjustment process. The adjustment plate 441 and the first magnet 411 are built into the chamber 412, and their excessive displacement is limited by the physical boundary of the side wall of the chamber 412, so as to achieve the synergistic optimization of the accuracy, anti-interference and structural compactness of the gap adjustment.

[0075] Understandably, referring to Figure 1 and Figure 2 In some embodiments of this utility model, the drive mechanism 300 includes: a drive motor 310, mounted on a fixed base 100; a transmission crankshaft 320, rotatably mounted on the fixed base 100, one end of which is connected to the output shaft of the drive motor 310; a rocker arm 330, one end of which is connected to the rhythm bracket 200, the other end of which has a connecting hole through which the transmission crankshaft 320 passes, and the rotation center of the transmission crankshaft 320 is eccentrically positioned with respect to the center of the connecting hole; wherein, the fixed base 100 is provided with an elastic pushing structure 500, which is connected to the rocker arm 330, and the elastic pushing structure 500 is used to push the inner wall of the connecting hole to maintain contact with the transmission crankshaft 320.

[0076] With the above structure, due to the eccentric design, the rotational motion generated by the drive motor 310 is converted into eccentric motion, thereby generating a periodic torque on the transmission crankshaft 320. This causes the rhythmic bracket 200 to reciprocate back and forth relative to the fixed base frame 100. The structure is compact and provides flexible, efficient and precise motion control. At the same time, through the thrust of the elastic push structure 500, the elastic push structure 500 continuously applies force, keeping the inner wall of the rocker arm 330 connection hole in stable contact with the transmission crankshaft 320. This eliminates motion lag or impact caused by gaps and avoids wear problems caused by rigid connections. In addition, the elastic push structure 500 can absorb small vibrations and impacts during the motion process, reduce mechanical stress concentration, and significantly improve the durability of the mechanism.

[0077] Specifically, in this embodiment, the fixed base frame 100 is provided with a fixed plate, the fixed plate is provided with a first positioning post, the transmission crankshaft 320 is provided with a second positioning post, and the elastic push structure 500 is a cylindrical spring. One end of the cylindrical spring is sleeved and connected to the first positioning post, and the other end is sleeved and connected to the second positioning post, ensuring that the axis of the cylindrical spring is always precisely aligned with the transmission crankshaft 320. The structure is simple, and while ensuring the elastic pre-tightening effect, it significantly improves the motion accuracy and long-term reliability of the mechanism, and is easy to maintain and adjust.

[0078] Of course, in some examples, the aforementioned elastic push structure 500 can also be an elastic plate, etc.

[0079] Of course, in other examples, the drive mechanism 300 can also be magnetically driven, using a magnet and a coil. By changing the energization state of the coil, an attractive or repulsive force is generated between the coil and the magnet, thereby driving the rhythm chair to move back and forth.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
