Abstract
Description
A stepless amplitude horizontal rhythm device and its adjustment method Technical Field
[0001] This invention relates to the field of rhythmic device technology, specifically to a stepless amplitude horizontal rhythmic device and its adjustment method. Background Technology
[0002] Massage chairs are generally used in living spaces such as homes and nursing homes, health and rehabilitation institutions such as rehabilitation centers, work and leisure spaces such as offices, hotels and resorts, and sports-related venues, providing relaxation and recovery assistance for different groups of people.
[0003] Massage chairs are typically equipped with various sensors that collect a range of data during use, such as pressure distribution across different body parts, massage duration, massage frequency, preferred massage modes, and intensity. This data reflects the user's level of tension, fatigue, and potential localized muscle problems. The intelligent healthcare ecosystem, on the other hand, encompasses a broader and deeper range of medical and health data, including user medical records, physical examination reports, genetic information, and daily physiological indicator monitoring data. When the data collected by massage chairs is integrated with this data from the intelligent healthcare ecosystem, it can provide medical professionals with a more comprehensive profile of the user's health. Through in-depth analysis of this integrated data, doctors can more accurately assess the user's overall health condition.
[0004] As a large-capacity massage product, a single massage function is no longer sufficient to meet consumer needs. Therefore, the patent with authorization announcement number CN205054760U discloses a massage chair with a human body weight detection function. The massage chair proposed in this patent has both massage function and weight detection function, which can meet the needs of people to detect their own weight index during the massage.
[0005] However, the massage chair in the aforementioned patent lacks a horizontal rhythm function, while existing massage chairs with horizontal rhythm functions are unstable in motion and generate significant inertia during operation, resulting in deficiencies in both user experience and smooth mechanical transmission. Furthermore, how to adjust the power of the horizontal rhythm according to the weight of different users is a current research direction. Therefore, this invention proposes a stepless amplitude horizontal rhythm device and adjustment method. Technical issues
[0006] The purpose of this invention is to provide a continuously variable amplitude horizontal rhythm device and adjustment method to solve the problems mentioned in the background. Technical solutions
[0007] To achieve the above objectives, the present invention provides the following technical solution: a continuously variable amplitude horizontal rhythm device, comprising a support plate and a mounting plate, characterized in that: a rhythm component for providing a rhythmic effect is disposed below the support plate, and an amplitude adjustment component is disposed on one side of the rhythm component; the amplitude adjustment component includes a second drive motor, a lead screw is fixedly connected to the output end of the second drive motor, an adjusting block is threadedly sleeved on the surface of the lead screw, an adjusting rod is rotatably connected to the other end of the adjusting block, and a lead screw protective seat is disposed at the other end of the lead screw;
[0008] The rhythmic component includes a first drive motor, the output end of which is provided with a worm gear transmission part. An eccentric wheel is provided on the surface of the worm gear transmission part. The eccentric wheel is horizontally oriented and will not be affected by gravity, causing jamming. The eccentric wheel passes through the interior of the swing block. One end of the swing block is rotatably connected to an adjusting rod, and the other end of the swing block is rotatably connected to a drive rod. The other end of the drive rod is rotatably connected to a connecting rod. A linear rail is fixedly connected to the surface of the connecting rod. A guide rail fixing seat is fixedly connected to the upper end of the linear rail. A guide rail is slidably connected to the upper end of the guide rail fixing seat. A shock-absorbing spring with a shock-absorbing effect is fixedly connected to the surface of the guide rail.
[0009] Parallel connecting rods are rotatably mounted on the surfaces of the drive rod and the adjusting rod. These parallel connecting rods are V-shaped and positioned between the adjusting block and the drive rod to improve transmission stability. The swing block and the parallel connecting rods are arranged parallel to the bearing plate to improve motion smoothness. The other end of the shock-absorbing spring is fixedly connected to the linear rail via a bracket.
[0010] Below the rhythmic component is a support component for providing motion support and limiting; the support component includes a support frame and a detection end; several limiting plates are fixedly connected to the surface of the support frame, and the surface of the limiting plates is provided with a sliding groove, and the surface of the sliding groove is provided with a number of micro-holes for heat dissipation, and the linear guide slides on the surface of the sliding groove; a fixing plate and a limiting rod are fixedly connected to the surface of the support frame, and an arc-shaped limiting frame is fixedly connected to the surface of the fixing plate; a first drive motor and a second drive motor are fixed to the surface of the fixing plate, and an eccentric wheel rotates on the surface of the arc-shaped limiting frame; several sets of detection end are provided below the support frame.
[0011] Preferably, the support assembly further includes a piston cylinder and an extrusion block. An oil inlet pipe and an oil outlet pipe are connected through the surface of the piston cylinder. The oil inlet pipe is connected to an external lubricating oil, and the oil outlet pipe is connected to a micro-hole opened on the surface of the slide groove to improve the uniformity of lubrication. A one-way valve is provided inside both the oil inlet pipe and the oil outlet pipe. An extrusion rod is fixedly provided on the surface of the extrusion block.
[0012] Preferably, the stabilizing component includes a swing rod that rotates on the surface of the mounting plate, and an extrusion block that slides on the surface of the swing rod; a guide groove is provided on the surface of the swing rod, and the extrusion rod slides on the surface of the guide groove; a push block is fixedly connected to the surface of the swing rod.
[0013] Preferably, the stabilizing component further includes a slider that slides on the surface of a limiting rod, a mating rod that is fixedly connected to the surface of the slider and slides on the inner surface of the piston cylinder; and a push rod that is rotatably connected to the surface of the slider, with one end of the push rod slidably sleeved on the surface of the push block.
[0014] Preferably, the surface of the bearing plate is provided with a plurality of ventilation holes to improve heat dissipation; a plurality of load-bearing springs are fixedly provided on the surface of the mounting plate, and the plurality of load-bearing springs correspond to the upper and lower positions of the plurality of detection ends.
[0015] Preferably, the load-bearing spring is equipped with a pressure sensor for detecting the user's weight.
[0016] Preferably, the pressure sensor is used in conjunction with the intelligent control module and the safety monitoring module to further improve user experience and safety. The intelligent control module feeds back the measured data to an external network terminal through the pressure sensor. The network terminal can automatically or manually control the output power of the first drive motor and the second drive motor according to user needs, thereby meeting the needs of different users. When the safety monitoring module detects the user's weight through the pressure sensor, if the user's weight is low or high or changes instantaneously, the first drive motor and the second drive motor are always in a self-locking state to improve safety.
[0017] A method for adjusting a continuously variable amplitude horizontal rhythm device includes the following steps:
[0018] S1: The network terminal saves and analyzes the user weight data fed back by the load spring;
[0019] S2: Select automatic or manual adjustment mode according to user needs;
[0020] S3: During automatic adjustment, the heavier the user, the greater the output power of the first drive motor and the smaller the output power of the second drive motor; the lighter the user, the opposite is true. Beneficial effects
[0021] The beneficial effects of this invention are as follows:
[0022] 1. This invention uses rhythmic components to rhythmically propel the user's body, increasing the speed and flow of blood in the user's body, and relieving muscle fatigue and soreness. At the same time, it can automatically or manually adjust the power and amplitude of the rhythm according to the user's weight, providing a personalized massage experience for users of different weights, making the massage intensity and rhythm more in line with individual needs, and greatly improving the comfort and effect of the massage.
[0023] 2. This invention effectively reduces the inertia generated by the horizontal movement of the bearing plate through the shock-absorbing spring on the guide rail, while also serving as a limit and shock absorber. The second drive motor drives the lead screw to adjust the swing amplitude of the swing block, making the adjustment process more precise. The parallel connecting rod not only reduces the reaction force on the adjusting block during the swing block's movement but also further improves the stability of the rhythm component's movement. The rhythm component is arranged parallel to the bearing plate, meaning the eccentric wheel is horizontal and unaffected by gravity. In the prior art, the eccentric wheel is longitudinally positioned, which is affected by gravity and causes a jerking sensation. This invention allows for stepless adjustment of the swing amplitude, lead screw, and fixing method, reducing the probability of vibration and damage. Simultaneously, the consistent pressure experienced during movement also contributes to smooth movement and reduces jerking sensation.
[0024] 3. This invention, through the setting of intelligent control module and safety monitoring module, automatically adjusts the device's operating status according to the user's weight, and automatically locks the device for users who are too heavy or too light, ensuring the safety of the massage process and avoiding potential dangers.
[0025] 4. There is a V-shaped fixed structure, namely a parallel connecting rod, between the lead screw and the crank-connecting rod mechanism, which affects the up-and-down swing of the lead screw, avoids damage from long-term swing, and extends its service life.
[0026] 5. This invention achieves stepless amplitude rhythm through two drive motors. The second drive motor can freely adjust the amplitude of the rhythm, and the first drive motor can adjust the speed to achieve the frequency of the rhythm.
[0027] 6. The present invention improves the ability to set shock-absorbing springs on the guide rail, which can effectively reduce the inertia generated by the horizontal movement of the bearing plate. Since the guide rail is slidably connected to the guide rail fixing seat, when the guide rail reciprocates, if the guide rail has forward inertia, the presence of the shock-absorbing springs provides a back spring force, which has the effect of limiting and damping.
[0028] 7. The present invention provides a lead screw protection seat at the other end of the lead screw, which supports the lead screw. Attached Figure Description

[0043] Because existing massage chairs with horizontal rhythm function are unstable and generate a lot of inertia during operation, both the user experience and the smoothness of mechanical transmission are insufficient; and how to adjust the power of horizontal rhythm according to the weight of different users is the current research direction.
[0044] Therefore, as shown in Figures 1 and 2, the present invention proposes a stepless amplitude horizontal rhythm device, including a support plate 1 and a mounting plate 2. A rhythm component 100 for providing rhythm effect is provided below the support plate 1, and an amplitude adjustment component is provided on one side of the rhythm component 100. The amplitude adjustment component includes a second drive motor 110, and a lead screw 111 is fixedly connected to the output end of the second drive motor 110.
[0045] An adjusting block 112 is connected to the surface of the lead screw 111 via a threaded sleeve. A motor is installed inside the adjusting block 112. During normal operation, the second drive motor 110 operates, and the motor inside the adjusting block 112 is in the off state. The second drive motor 110 drives the lead screw 111 to rotate, controlling the sliding of the adjusting block 112 on the surface of the lead screw 111 to achieve amplitude adjustment. If the second drive motor 110 malfunctions, when the motor inside the adjusting block 112 starts, the lead screw 111 is in a locked state. The motor inside the adjusting block 112 drives the threaded sleeve to rotate. Since the lead screw 111 is in a fixed state, the rotation of the adjusting block 112 allows it to move on the surface of the lead screw 111, thus achieving amplitude adjustment. By setting two sets of amplitude adjustment power sources, the reliability and flexibility of the device can be improved. An adjusting rod 113 is rotatably connected to the other end of the adjusting block 112, and a lead screw protection seat is provided at the other end of the lead screw 111.
[0046] Furthermore, the rhythm component 100 includes a first drive motor 101. The output end of the first drive motor 101 is provided with a worm gear transmission part 102. An eccentric wheel 103 is provided on the surface of the worm gear transmission part 102. The eccentric wheel 103 is horizontally positioned so as not to be affected by gravity and thus not to cause jamming. The eccentric wheel 103 passes through the interior of the swing block 104. One end of the swing block 104 is rotatably connected to the adjusting rod 113. The other end of the swing block 104 is rotatably connected to the drive rod 105. The other end of the drive rod 105 is rotatably connected to the connecting rod 106. A linear rail 107 is fixedly connected to the surface of the connecting rod 106. A guide rail fixing seat is fixedly connected to the upper end of the linear rail 107. A guide rail 108 is slidably connected to the upper end of the guide rail fixing seat. A shock-absorbing spring 109 with a shock-absorbing effect is fixedly connected to the surface of the guide rail 108.
[0047] Furthermore, a parallel connecting rod 114 is rotatably provided on the surfaces of the drive rod 105 and the adjusting rod 113. The parallel connecting rod 114 is V-shaped and positioned between the adjusting block 112 and the drive rod 105 to improve the stability of the transmission. The swing block 104 and the parallel connecting rod 114 are arranged parallel to the bearing plate 1 to improve the smoothness of the movement. The other end of the shock-absorbing spring 109 is fixedly connected to the linear guide 107 through a bracket.
[0048] Furthermore, a support assembly 200 for providing motion support and limiting is provided below the rhythm component 100; the support assembly 200 includes a support frame 201 and a detection end 207. Several limiting plates 202 are fixedly connected to the surface of the support frame 201. The surface of the several limiting plates 202 is provided with a sliding groove 203. The surface of the sliding groove 203 is provided with several micro holes for heat dissipation. The linear guide 107 slides on the surface of the sliding groove 203. A fixing plate 204 and a limiting rod 209 are fixedly connected to the surface of the support frame 201. An arc-shaped limiting frame 205 is fixedly connected to the surface of the fixing plate 204. The first drive motor 101 and the second drive motor 110 are fixed to the surface of the fixing plate 204. The eccentric wheel 103 rotates on the surface of the arc-shaped limiting frame 205. Several sets of detection end 207 are provided below the support frame 201.
[0049] It should be noted that the amplitude modulation component can also use an electric push rod or an electric adjuster. The adjustment block 112 is moved by the electric push rod or electric adjuster to adjust the amplitude of the rhythm component.
[0050] Furthermore, as shown in Figures 8 and 9, the support assembly 200 also includes a piston cylinder 206 and an extrusion block 208. An oil inlet pipe 2061 and an oil outlet pipe 2062 are connected through the surface of the piston cylinder 206. The oil inlet pipe 2061 is connected to an external lubricating oil, and the oil outlet pipe 2062 is connected to a micro-hole on the surface of the slide groove 203 to improve the uniformity of lubrication. A one-way valve is provided inside both the oil inlet pipe 2061 and the oil outlet pipe 2062. An extrusion rod 2081 is fixedly provided on the surface of the extrusion block 208.
[0051] As shown in Figure 10, the stabilizing component 300 includes a swing rod 301, which rotates on the surface of the mounting plate 2, and the pressing block 208 slides on the surface of the swing rod 301; a guide groove 302 is provided on the surface of the swing rod 301, and the pressing rod 208 slides on the surface of the guide groove 302; a push block 303 is fixedly connected to the surface of the swing rod 301.
[0052] Furthermore, the stabilizing component 300 also includes a slider 305, which slides on the surface of the limiting rod 209. A mating rod 306 is fixedly connected to the surface of the slider 305, and the mating rod 306 slides on the inner surface of the piston cylinder 206. A push rod 304 is rotatably connected to the surface of the slider 305, and one end of the push rod 304 is slidably sleeved on the surface of the push block 303.
[0053] Furthermore, the surface of the support plate 1 is provided with several ventilation holes 11 to improve heat dissipation; several load-bearing springs 21 are fixedly installed on the surface of the mounting plate 2, and the several load-bearing springs 21 correspond to the vertical positions of several detection ends 207; the support plate 1 can be pushed by the rhythm component to achieve adjustable horizontal rhythm in the horizontal front and back direction, and the amplitude can be determined according to the product requirements.
[0054] Furthermore, a pressure sensor is installed inside the load-bearing spring 21 to detect the user's weight.
[0055] Furthermore, as shown in Figures 11 and 12, the pressure sensor is used in conjunction with the intelligent control module and the safety monitoring module to further improve the user experience and safety. The intelligent control module feeds back the measured data to the external network terminal through the pressure sensor. The network terminal can automatically or manually control the output power of the first drive motor 101 and the second drive motor 110 according to the user's needs, thereby meeting the needs of different users. When the safety monitoring module detects the user's weight through the pressure sensor, if the user's weight is low or high or changes instantaneously, the first drive motor 101 and the second drive motor 110 are always in a self-locking state to improve safety.
[0056] As shown in Figure 11, a method for adjusting a continuously variable amplitude horizontal rhythm device includes the following steps:
[0057] S1: The network terminal saves and analyzes the user weight data fed back by the load spring 21;
[0058] S2: Select automatic or manual adjustment mode according to user needs;
[0059] S3: During automatic adjustment, the heavier the user, the greater the output power of the first drive motor 101 and the smaller the output power of the second drive motor 110; the lighter the user, the opposite is true.
[0060] Working principle: In the rhythm component 100, the first drive motor 101 starts, and its output end drives the eccentric wheel 103 to rotate through the worm gear transmission part 102; the rotation of the eccentric wheel 103 causes the swing block 104 to rotate eccentrically, and the eccentric wheel 103 and the swing block 104 on its outer side form a cam mechanism; the drive rod 105 at one end of the swing block 104 and the adjusting rod 113 at the other end move accordingly, forming an amplitude crank-connecting rod mechanism; the drive rod 105 drives the connecting rod 106 to move, so that the linear rail 107 on the connecting rod 106 slides along the slide groove 203 to realize the horizontal rhythm function.
[0061] At the same time, the second drive motor 110 drives the lead screw 111 to rotate. The lead screw 111 and the lead screw nut are threadedly connected. The lead screw nut is fixedly connected to the adjusting block 112. Therefore, the adjusting block 112 will move with the lead screw nut. Then, the angle of the swing block 104 is changed through the adjusting rod 113. That is, the length of the rocker arm in the crank rocker mechanism is changed, thereby realizing the stepless amplitude effect, that is, adjusting the amplitude of the reciprocating motion of the linear guide 107.
[0062] The parallel connecting rod 114 improves the stability of the transmission in this process. The damping spring 109 on the guide rail 108 can effectively reduce the inertia generated by the horizontal movement of the bearing plate. Since the guide rail is slidably connected to the guide rail fixed seat, when the guide rail reciprocates, if the guide rail has forward inertia, the presence of the damping spring 109 provides a back spring force, which has the effect of limiting and damping.
[0063] In the support assembly 200, the linear guide 107 slides within the groove 203 of the limiting plate 202 to provide support and guidance; the micro-holes on the surface of the groove 203 are used for heat dissipation; the arc-shaped limiting frame 205 on the fixing plate 204 limits the rotation of the eccentric wheel 103.
[0064] When a user sits on the support plate 1, their weight will press down on the support assembly 200, causing the pressing block 208 in the support assembly 200 to slide downward inside the swing rod 301. At the same time, the pressing rod 2081 slides in the guide groove 302, causing the swing rod 301 to rotate.
[0065] When the swing rod 301 rotates, the push block 303 on its surface pushes the push rod 304, and the push rod 304 pushes the slider 305 to slide on the limit rod 209. The mating rod 306 on the slider 305 slides inside the piston cylinder 206, thereby squeezing the lubricating oil inside the piston cylinder 206 and discharging it through the oil drain pipe 2062 to the surface of the micro-hole on the surface of the slide groove 203, so as to achieve uniform lubrication and improve the smoothness of movement.
[0066] The heavier the weight, the farther the slider 305 slides, and the better the stability. A reset spring is provided on the limit rod 209 to provide a reset function.
[0067] The heavier the user, the greater the pressure and wear between the linear guide 107 and the slide 203. The heavier the user, the farther the slider 305 moves. The heavier the user, the more lubricating oil is discharged from the piston cylinder 206. Thus, the amount of lubricating oil is automatically controlled according to the user's weight, avoiding lubricating oil waste and improving the service life of the device.
[0068] When the user sits on the support plate 1, the pressure sensor in the load spring 21 on the mounting plate 2 detects the user's weight and feeds the data back to the external network terminal.
[0069] As shown in Figure 12-13, in the intelligent control module, the network terminal receives and analyzes the data from the pressure sensor. The user can choose between automatic or manual adjustment modes. In automatic adjustment mode, if the user is heavier, the output power of the first drive motor 101 increases to provide a stronger rhythmic effect, while the output power of the second drive motor 110 decreases, thereby slowing down the frequency of rhythmic distance adjustment and improving stability. If the user is lighter, the output power of the first drive motor 101 decreases to provide a smoother rhythmic effect, while the output power of the second drive motor 110 increases, thereby increasing the frequency of rhythmic distance adjustment to obtain a more comfortable massage experience.
[0070] In the safety monitoring module, if the pressure sensor detects that the user's weight is too low or too high, the first drive motor 101 and the second drive motor 110 will gradually enter a self-locking state until they stop working to ensure safe use. At the same time, when the user gets up, if the pressure detected by the pressure sensor changes instantaneously, the safety monitoring module will immediately shut down the first drive motor 101 and the second drive motor 110 to improve safety.

It should be noted that those skilled in the art can make various changes and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
