Description

Body relaxation adjustment device Technical Field

[0001] The invention belongs to the technical field of fitness equipment, and in particular relates to a body relaxation and adjustment device. Background Art

[0002] In their Chinese invention patent application, publication number CN1041458A, the applicant disclosed a step-type body relaxation and adjustment device. When the power assembly is operating, the driving wheel drives the driven wheel to rotate via a transmission belt, which in turn drives the rotating shaft to rotate, achieving the axial rotation of the cam. When the bottom surface of the pedal contacts the first curved edge, the pedal is gradually lifted upward by the first curved edge to its highest point as the cam rotates. After the bottom surface of the pedal leaves the first curved edge, the pedal freely falls until its bottom surface contacts the second curved edge, achieving repeated vertical lifting and lowering motion as the cam rotates around its axis. The advantages of this device are that it fully exercises and effectively relaxes the lumbar muscles, relieves lumbar muscle strain, chronic back pain, and other lumbar conditions, achieves a relaxing effect, and prevents brain damage from excessive vibration during exercise.

[0003] To address the issues of high noise levels and low comfort levels in patent application CN1041458A, the applicant disclosed in Chinese invention patent application CN206526445U a fitness device with automatically alternating pedal lifts. The device comprises a base plate, left and right pedals, a power assembly that drives the pedals to alternately lift and lower, a guide assembly that vertically guides the pedals, a load-bearing spring disposed vertically between the base plate and the pedals, and a muffler spring disposed vertically between the base plate and the pedals to offset pedal impact. The muffler spring is higher than the load-bearing spring and has a much lower elastic force than the load-bearing spring. In this invention, both left and right pedals are equipped with load-bearing and muffler springs. When the pedals are unloaded and the fitness device is operating, there is no impact between the pedals and the muffler springs. This also avoids or reduces the impact of the pedals on the load-bearing springs, effectively reducing the impact between the springs and the pedals, lowering noise, and improving comfort.

[0004] To address the significant shortcomings of patent CN206526445U in terms of ground vibration intensity, the applicant disclosed in Chinese invention patent authorization number CN21132983U a fitness device with automatically alternating lifting pedals. The device comprises a main body, a body relaxation adjustment device, and a buffer assembly disposed on a base plate. The buffer assembly comprises a first foot group and a second foot group, each of which is vertically distributed. The first foot group comprises four upper foot groups, and the second foot group comprises four lower foot groups. Both the upper and lower foot groups are elastic. The beneficial effect of the invented body relaxation adjustment device is that it is provided with at least two levels of buffer foot groups, effectively reducing vibration intensity, minimizing noise, and enhancing exercise comfort.

[0005] After years of improvement by the applicant, the solution in patent CN21132983U has been able to provide users with a better user experience. However, there are still some shortcomings that limit its application and promotion: 1. The vibration intensity is still relatively large, and the impact on the surrounding environment is more obvious; 2. The vertical lifting of the pedal must be equipped with a guide structure, which is easily damaged; 3. The force is transmitted by the cam, and the cam generates obvious friction and heat, has a short service life, and is more difficult to maintain; 4. Since the torque required by the cam is large, the requirements for motor power and reducer are high; 5. The load-bearing spring is relied upon to offset the weight of the free fall of the human body. The load-bearing spring needs to be replaced to adapt to people of different weights, which is not very convenient to use; 6. The cam diameter is large, and some of the low-frequency vibrations generated have slightly greater negative side effects on the human body; the overall components are more, the weight is larger, and the cost is higher; 7. The vibration impact force is only in the vertical direction, and the direction is single.

[0006] In addition, other similar fitness devices, such as fat-throwing machines and rhythm machines, each have their own advantages and disadvantages. A disadvantage of a fat-throwing machine (see Figure 16 for its working method) is that the user stands on the same pedal and swings left and right at a high frequency. Due to structural reasons, the left and right sides of the same pedal only transmit the greatest impact vibration force to the feet when swinging upward. At this time, the force applied to the feet by the pedals is directed upward from the center of the body. Furthermore, in normal use, to obtain sufficient vibration impact force, the feet must be separated by a certain distance from each other while standing on the same pedal. At this time, the force transmitted to the feet by the pedals is directed upward from the center of the body. The angle formed by the separated feet further guides the force transmission, ultimately causing the direction of the force transmitted to the body to form a force intersection at a certain height on the body (usually in the waist and back, where internal organs are concentrated). This force intersection is very likely to cause excessive force stimulation at this force intersection, resulting in damage. Generally, mild symptoms such as abdominal numbness and discomfort may occur in the early stages of use, but further damage may occur to internal organs at the intersection.

[0007] The disadvantage of the rhythm machine (whose working method can be seen in Figure 15) is that the user stands on the same pedal and moves vertically up and down at a high frequency, which causes greater vibration to the human brain. In addition, since it is necessary to ensure the vertical movement of the pedal, a guide structure is required, which has more components and is relatively expensive. Summary of the Invention

[0008] The present invention addresses the shortcomings of existing body relaxation adjustment devices with automatic alternating pedals, such as the left and right pedals alternately rising and falling vertically, the large number of parts, and the unreasonable structure. The present invention provides a body relaxation adjustment device, in which the left and right human body support components alternately swing up and down, eliminating the vertical guide structure, reducing motor requirements, and having a more reasonable structure. In addition, while the human body is subjected to vertical impact vibration force, the human body also increases subtle horizontal swings, so that the human body is stimulated by force in more dimensions, thereby improving the comfort of use and the relaxation adjustment effect.

[0009] To achieve the above-mentioned purpose, the present invention adopts the following technical solution: a body relaxation adjustment device, the body relaxation adjustment device comprising:

[0010] base;

[0011] Two left and right human body support components, the two human body support components are arranged on the base so as to swing up and down relative to the horizontal plane;

[0012] a motor, disposed on the base;

[0013] The driving device drives the two human body support components to swing up and down alternately relative to the horizontal plane under the action of the motor.

[0014] The body relaxation and adjustment device of the present invention uses a driving device to cause two human support assemblies to alternately swing up and down. The two feet of a person are supported by the two human support assemblies respectively. Under the action of the body relaxation and adjustment device, the two feet alternately swing up and down. This is different from the two pedals of the applicant's previous application that alternately rise and fall vertically, and is also different from the single pedal of the fat-shaking machine that swings left and right around the center in the left and right directions, and is also different from the single pedal of the rhythm machine that rises and falls vertically. Thus, a body relaxation and adjustment device different from the existing ones is provided. Under normal circumstances, the two feet are respectively upright on the two human support assemblies. The two human support assemblies alternately swing up and down. Compared with the fat-shaking machine, the pressure on the human internal organs is greatly reduced, and compared with the rhythm machine, the impact on the human head is greatly reduced. Compared with the vertical alternation of the two pedals, the structure is more reasonable. The two human support assemblies alternately swing up and down, which means that when one human support assembly swings upward, the other human support assembly swings downward. When using the body relaxation and adjustment device of the present invention, the two feet can also stand on the same human support assembly to vibrate in an up and down swinging manner. The swing connection mechanism links the two human support assemblies so that the two human support assemblies swing up and down synchronously. The body relaxation adjustment device of the present invention can also be used for a human body (left and right buttocks) to sit on a two-person body support assembly.

[0015] As an improvement, the driving device includes:

[0016] an eccentric transmission mechanism, connecting the motor and a human body support component and causing the human body support component to swing up and down;

[0017] The swing connection mechanism links the two human body support components so that the two human body support components swing up and down alternately.

[0018] As an improvement, the swing connection mechanism includes a connection seat mounted on the base, a swing link pivotally connected to the connection seat at its center, and two connection assemblies mounted at either end of the swing link. The connection assemblies include connectors pivotally connected to the swing link and the body support assembly, respectively. In this manner, the force output by the motor passes through one body support assembly to the other, ensuring the alternating up and down swinging of the two body support assemblies.

[0019] As an improvement, the connecting assembly also includes a first shaft fixed to the swing link, a second shaft fixed to the human body support assembly, a first bearing connecting the first shaft and the connecting member, and a second bearing connecting the second shaft and the connecting member.

[0020] As an improvement, the connecting member includes a base and two stepped holes opened on the base, the stepped holes include a bearing hole with a larger aperture and an axial hole with a smaller aperture, the first bearing and the second bearing are installed in the bearing holes, and the first shaft and the second shaft pass through the axial holes.

[0021] As an improvement, the connecting assembly also includes a pressing plate fixed on the connecting member to prevent the first bearing and the second bearing from falling out. An axial hole is opened on the pressing plate, and the pressing plate is fixed to the connecting member by screws; the connecting member is in an 8-shape.

[0022] As an improvement, the eccentric transmission mechanism includes an eccentric shaft driven to rotate by the motor, a connecting member rotatably connected to the eccentric shaft and a human body support component, a pulley assembly connecting the output shaft of the motor and the eccentric shaft, and a seat bearing supporting the eccentric shaft.

[0023] As an improvement, the left and right positions of the connecting piece of the eccentric transmission mechanism and the human body support assembly are adjustable to adjust the swing amplitude. Specifically, the left and right positions of the entire eccentric transmission mechanism and the motor are adjustable.

[0024] As an improvement, the driving device includes:

[0025] A first eccentric shaft driven to rotate by the motor, a first connecting member rotatably connected to the first eccentric shaft and one of the human body support components, a first pulley assembly connecting the output shaft of the motor and the first eccentric shaft, a first seat bearing supporting the first eccentric shaft, a second eccentric shaft driven to rotate by the motor, a second connecting member rotatably connected to the second eccentric shaft and another of the human body support components, a second pulley assembly connecting the first eccentric shaft and the second eccentric shaft, and a second seat bearing supporting the second eccentric shaft;

[0026] The eccentric portion of the first eccentric shaft and the eccentric portion of the second eccentric shaft are symmetrical with respect to the axis center of the output shaft of the motor, and the second pulley assembly is a synchronous pulley assembly or a deep groove pulley assembly.

[0027] As an improvement, the driving device includes:

[0028] pulley assembly;

[0029] A double-ended eccentric shaft connected to the driven pulley of the pulley assembly;

[0030] Two sets of connecting assemblies, each comprising a connecting member rotatably connected to the double-headed eccentric shaft and the human body support assembly. This structure of the driving device is more streamlined and compact than the aforementioned structure consisting of an eccentric transmission mechanism and a swing connection mechanism.

[0031] As an improvement, the connection assembly further comprises a connection frame fixedly connected to the human body support assembly, the connection frame comprising a vertical portion perpendicular to the human body support assembly and an extension portion with an axial hole.

[0032] As an improvement, the body relaxation adjustment device further comprises a bottom shell, the base is arranged above the bottom shell, and a plurality of bottom feet are arranged below the bottom shell;

[0033] The body relaxation adjustment device further comprises an upper cover fixedly connected to the upper part of the human body support component, and a foot pad is provided on the upper cover;

[0034] The human body support assembly swings up and down with the horizontal plane as the center;

[0035] The swing angle of the human body support component is 0.3-2.5°;

[0036] The body relaxation and adjustment device further comprises a controller for controlling the motor, and the controller realizes timing and speed regulation functions.

[0037] The body relaxation adjustment device of the present invention is mainly used for whole-body passive vibration relaxation adjustment of the human body when the human body is in a relaxed upright or sitting state.

[0038] The beneficial effects of the body relaxation and adjustment device of the present invention are: providing a body relaxation and adjustment device different from the existing one, in which the two feet usually stand on two human support components respectively, and the two human support components swing up and down alternately, which greatly reduces the squeezing damage to the human internal organs compared to the fat-shaking machine, greatly reduces the impact on the human head compared to the rhythm machine, and the overall structure is simpler and more reasonable compared to the vertical alternating rise and fall of two pedals; the vibration amplitude is small and the vibration frequency is high, with fewer negative low-frequency vibration side effects on the human body and less vibration impact on the surrounding environment; the production cost is low, the service life is long, the maintenance is easier, and it is more adaptable to different groups of people. Of particular importance is the dual human support assembly body relaxation and adjustment device of the present invention. During normal use, the two feet stand upright in a natural and relaxed manner on the left and right human support assemblies, respectively. Through the small swing of the two human support assemblies, the two human support assemblies can generate sufficient impact vibration force on the human body through the two feet. Moreover, at this time, the directions of the forces of the alternating impact vibrations of the left and right human support assemblies themselves do not have an intersection. Therefore, the impact vibration force generated by the small alternating swing of the two human support assemblies will pass through the flesh tissue to form a safe, efficient, and continuous variety of vibration stretching torques that converge inside the body. This vibration stretching torque mainly occurs and acts on the human body's crotch and the entire waist and back area of ​​the joint area connecting the upper and lower parts of the human body, thereby playing an important role in the relaxation adjustment and strength stimulation of the entire human body. Through the stimulation brought by such deep vibration, the arrangement and combination state of various cells inside the human body can be quickly and efficiently adjusted, cell tissues can be activated, human metabolism can be promoted, and the body can be radiated with healthier vitality.

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0066] Example 1

[0067] 1 to 8 and 15 to 17 , a body relaxation adjustment device according to a first embodiment of the present invention includes:

[0068] Base 1;

[0069] Two left and right human body support components 5, the two human body support components 5 are arranged on the base 1 so as to swing up and down relative to the horizontal plane;

[0071] An eccentric transmission mechanism 3 connects the motor 2 and the human body support component 5 and causes the human body support component 5 to swing up and down;

[0072] The swing connection mechanism 4 links the two human body support components 5 so that the two human body support components 5 swing up and down alternately.

The eccentric transmission mechanism 3 uses a pulley assembly 31 instead of a transmission assembly such as a gear, so that the noise is lower. In other embodiments, the eccentric transmission mechanism can also use other structures such as a gear set and a worm gear. The driven wheel of the pulley assembly 31 is larger than its driving wheel, so that it can be achieved with the power of a smaller motor.

[0077] In this embodiment, the eccentric shaft 33 comprises a driven pulley connection portion, a connection portion with a bearing block 32, a bearing connection portion, and a retaining nut mounting portion. Circlip grooves are provided axially outward of the two bearing block 32 connection portions. The driven pulley is mounted on the driven pulley connection portion, two bearings are mounted on the bearing block 32 connection portion, retaining springs are provided in the retaining spring grooves, and a retaining nut is mounted on the retaining nut mounting portion. The bearing block 32 has two bearings spaced a certain distance apart.

[0078] In this embodiment, the swing connection mechanism 4 includes a connecting seat 41 provided on the base 1, a swing link 42 swingingly connected to the connecting seat 41 in the middle, and two groups of connecting components provided at both ends of the swing link 42. The connecting components are respectively connected to the swing link 42 and the human body support component 5, and convert the left and right swing of the swing link 42 into the alternating up and down swing of the two human body support components 5.

[0079] In this embodiment, the connecting assembly of the swing connection mechanism 4 includes a connecting member 34, a first shaft 35 fixedly connected to the swing link 42, a second shaft 37 fixedly connected to the body support assembly 5, a first bearing 36 connecting the first shaft 35 and the connecting member 34, and a second bearing 38 connecting the second shaft 37 and the connecting member 34. The connecting assembly also includes a U-shaped connecting frame 30 fixedly connected to the second shaft 37 and the body support assembly 5. To mount the first shaft 35 and the connecting member 34, the swing link 42 is constructed of a square tube. Notches are provided on the upper surfaces of both ends of the swing link 42, and a hole is provided in the vertical portion of the swing link 42 for mounting the first shaft 35. In other embodiments, the connecting frame 30 may also have other shapes. The eccentric transmission mechanism 3 uses the same structure as the connecting assembly of the swing connection mechanism 4 to connect the eccentric shaft 33 and the body support assembly 5 (omitting the first shaft 35, which is replaced by the eccentric shaft 33).

[0080] In this embodiment, the connecting member 34 includes a base and two stepped holes opened on the base. The stepped holes include a bearing hole with a larger aperture and an axial hole with a smaller aperture. The first bearing 36 and the second bearing 38 are installed in the bearing holes, and the first shaft 35 and the second shaft 37 pass through the axial holes.

[0081] In this embodiment, the connecting assembly also includes a pressing plate 39 fixed on the connecting member 34 to prevent the first bearing 36 and the second bearing 38 from falling out. An axial hole is provided on the pressing plate 39, and the pressing plate 39 is fixed to the connecting member 34 by screws; the connecting member 34 is in an 8-shape.

[0082] In this embodiment, the eccentric transmission mechanism 3 and the swing connection mechanism 4 use the same connecting member 34 , second shaft 37 , first bearing 36 , second bearing 38 and pressing piece 39 .

[0083] In this embodiment, the body relaxation adjustment device further includes a bottom shell, the base 1 is arranged above the bottom shell, and a plurality of feet are arranged below the bottom shell.

[0084] In this embodiment, the body relaxation adjustment device further includes an upper cover fixedly connected to the upper part of the human body support component 5, and a foot pad is provided on the upper cover.

[0085] In this embodiment, the human body support assembly 5 swings up and down relative to a horizontal plane, i.e., the lowest position of the support surface of the human body support assembly 5 is below the horizontal plane, and the highest position is above the horizontal plane. More specifically, the human body support assembly 5 swings up and down with the horizontal plane as the center plane, i.e., the lowest and highest positions are at equal angles from the horizontal plane, thereby providing a comfortable user experience and reducing the output torque of the motor 2.

[0086] In this embodiment, the swing angle of the human body support component 5 is 0.3-2.5°. The swing angle of the human body support component 5 is the angle between the lowest position and the highest position when it swings.

[0087] In this embodiment, the pulley assembly 31 connecting the motor 2 and the eccentric shaft 33 is arranged adjacent to the swing connection mechanism 4. In other embodiments, the pulley assembly 31 can also be arranged at the end of the motor 2 away from the swing connection mechanism 4 to facilitate the installation of the pulley assembly 31.

[0088] In this embodiment, the connection structures between the eccentric shaft 33 and the human body support component 5 and between the first shaft 35 and the human body support component 5 are the same, that is, they all use the first bearing 36, the 8-shaped connecting member 34, the second bearing 38, and the 8-shaped pressing piece 39.

[0089] In this embodiment, the hole distance between the two bearing holes of the 8-shaped connecting member 34 is between 30 and 60 mm.

[0090] In this embodiment, in order to adjust the swing amplitude of the human body support component 5, the eccentric transmission mechanism 3 can be set to be movable. By adjusting the connection position of the eccentric transmission mechanism 3 and the human body support component 5, a U-shaped part is used. The U-shaped part is connected to the human body support component 5 by screws, and multiple groups of mounting holes are set on the human body support component 5 and the base 1.

[0091] The working principle of the body relaxation adjustment device of this embodiment is: the motor 2 drives the eccentric shaft 33 to rotate through the pulley assembly 31, and the right human body support assembly 5 is swung up and down around its swing axis located at the end of the base 1 through the eccentric shaft 33, the first bearing 36, the 8-shaped connecting piece 34, the second shaft 37, and the second bearing 38. When the right human body support assembly 5 swings up and down, the swing link 42 is swung up and down around its middle part through the first shaft 35, the first bearing 36, the 8-shaped connecting piece 34, the second shaft 37, and the second bearing 38 on the right side of the swing connection mechanism 4, so that the left part of the swing link 42 also swings up and down, and then the left human body support assembly 5 is swung up and down through the first shaft 35, the first bearing 36, the 8-shaped connecting piece 34, the second shaft 37, and the second bearing 38 on the left side of the swing connection mechanism 4. At the same time, since the left and right human body support assemblies 5 are linked, the left and right human body support assemblies 5 are alternately swung up and down.

[0092] The beneficial effects of the double human support component 5 body relaxation adjustment device of the present invention are: providing a body relaxation adjustment device different from the existing one, normally the two feet stand on the two human support components 5 respectively, and the two human support components 5 swing up and down alternately, which greatly reduces the squeezing damage to the human internal organs compared to the fat-shaking machine, greatly reduces the impact on the human head compared to the rhythm machine, and is simpler and more reasonable than the two pedals that alternately rise and fall vertically; the vibration amplitude is small and the vibration frequency is high, with fewer negative low-frequency vibration side effects on the human body and less vibration impact on the surrounding environment; the production cost is low, the service life is long, maintenance is easier, and it is more adaptable to different groups of people.

[0093] Of particular importance is the dual human support assembly body relaxation and adjustment device of the present invention. During normal use, the two feet stand upright in a natural and relaxed manner on the left and right human support assemblies, respectively. Through the small swing of the two human support assemblies, the two human support assemblies can generate sufficient impact vibration force on the human body through the two feet. Moreover, at this time, the directions of the forces of the alternating impact vibrations of the left and right human support assemblies themselves do not have an intersection. Therefore, the impact vibration force generated by the small alternating swing of the two human support assemblies will pass through the flesh tissue to form a safe, efficient, and continuous variety of vibration stretching torques that converge inside the body. This vibration stretching torque mainly occurs and acts on the human body's crotch and the entire waist and back area of ​​the joint area connecting the upper and lower parts of the human body, thereby playing an important role in the relaxation adjustment and strength stimulation of the entire human body. Through the stimulation brought by such deep vibration, the arrangement and combination state of various cells inside the human body can be quickly and efficiently adjusted, cell tissues can be activated, human metabolism can be promoted, and the body can be radiated with healthier vitality.

[0094] In other embodiments, in order to accommodate people who like to sit and those who cannot or find it difficult to stand, the distance between the left and right body support components in the middle can be redesigned to be closer (mainly for sitting use) or adjusted (the distance is adjustable, taking into account both standing and sitting use). The distance is generally set at about 8 mm. At the same time, the height of the body support components from the ground is increased (mainly for sitting use) or adjusted (the height is adjustable, taking into account both standing and sitting use), so that users can sit more comfortably on the left and right body support components.

[0095] In other embodiments, when the user sits on the left and right body support components, auxiliary components such as a backrest and armrests may also be provided.

[0096] In other embodiments, in order to adjust the swing amplitude of the human body support component, the position of the motor and the eccentric transmission mechanism in the left and right directions can also be set to be adjustable.

[0101] Example 2

[0102] 9 to 12 and 15 to 17 , a body relaxation adjustment device according to a second embodiment of the present invention is shown. The body relaxation adjustment device includes:

[0103] Base 1;

[0104] A motor 2 is provided on the base 1;

[0105] Two left and right human body support components 5, the two human body support components 5 are arranged on the base 1 so as to swing up and down relative to the horizontal plane;

[0106] Pulley assembly 31;

[0107] A double-ended eccentric shaft 6 is connected to the driven pulley of the pulley assembly 31;

[0108] Two groups of connecting components 7 are rotatably connected to the double-headed eccentric shaft 6 and the human body supporting component 5.

[0109] In this embodiment, the swing axes of the two human body support components 5 are located at opposite ends in the left-right direction, that is, at both ends in the left-right direction, and the swing axes of the two human body support components 5 are parallel and at the same height.

[0110] In this embodiment, the motor 2 drives the double-headed eccentric shaft 6 to rotate through the pulley assembly 31. The rotation of the double-headed eccentric shaft 6 drives the connecting members 34 at both ends thereof to move, thereby causing the left and right human body support assemblies 5 to swing up and down alternately.

[0111] In this embodiment, the connecting assembly 7 includes a connecting member 34 that is rotatably connected to the double-ended eccentric shaft 6 and the body support assembly 5. The connecting member 34 is the same as that in the first embodiment. In other embodiments, the connecting member may also adopt other structures. The connecting assembly 7 also includes a first bearing 36, a second shaft 37, a second bearing 38, and a pressing plate 39.

[0112] In this embodiment, the connection structure between the double-headed eccentric shaft 6 and the human body support component 5 can refer to the connection structure between the eccentric shaft 33 and the human body support component 5 in the first embodiment.

[0113] In this embodiment, two seated bearings 32 are provided to support the double-ended eccentric shaft 6. The two eccentric portions of the double-ended eccentric shaft 6 are located at either end and are balanced relative to the axis of the output shaft of the motor 2. The specific eccentric portion setting is determined by the vertical angle formed by the two sets of connecting components when installed, ensuring that the human body support assembly can achieve regular alternating up and down swinging.

[0114] In this embodiment, the connecting assembly 7 also includes a connecting frame 30 fixedly connected to the human body support assembly 5, and the connecting frame 30 includes a vertical portion 301 perpendicular to the human body support assembly 5 and an extension portion 302 with an axial hole. The extension portion 302 is rotatably connected to the connecting member 34 via a second shaft 37. The vertical portion 301 of the connecting frame 30 includes two parallel walls and a connecting wall between the two parallel walls. The extension portion 302 of the connecting frame 30 is perpendicular to the vertical portion 301. The extension portion 302 includes two parallel portions and a connecting portion between the two parallel portions. The two parallel portions have an axial hole at one end away from the vertical portion 301, and the length of the connecting portion is shorter than the parallel portion to avoid the connecting member 34. In other embodiments, the extension portion 302 may also be at an obtuse angle relative to the vertical portion 301.

[0115] In this embodiment, when the left and right body support assemblies 5 are swung to their maximum height difference, the vertical angle formed by the two sets of connecting assemblies 7 is minimized (zero). This requires only that the connecting frame 30 below the two body support assemblies 5 be formed with a roughly L-shaped lateral surface and the hole for mounting the second shaft 37 of the connecting member 34 be positioned directly above the double-ended eccentric shaft 6 (also on the left-right centerline of the body relaxation device). At this point, the eccentric portions at each end of the double-ended eccentric shaft 6 are positioned opposite each other. With this structure, the connecting members 34 of the connecting assembly 7 are essentially in a vertical position. The connecting frame 30 can be secured to the body support assemblies 5 by welding or other means.

[0116] The structure of the driving device of this embodiment (double-headed eccentric shaft 6 plus two sets of connecting components) is more optimized than the driving device of the first embodiment (eccentric transmission mechanism 3 plus swing connecting mechanism 4).

[0117] In this embodiment, the swing amplitude of the body support assembly 5 can be varied by selecting a double-ended eccentric shaft 6 with varying degrees of eccentricity (the distance between the axis of the eccentric portion and the central axis of the double-ended eccentric shaft 6). The swing amplitude of the body support assembly 5 can also be varied by changing the left-right position of the connecting assembly relative to the body support assembly 5.

[0118] In this embodiment, the double-headed eccentric shaft 6 is an integral part. In other embodiments, in order to facilitate the installation of the driven wheel on the double-headed eccentric shaft 6, two shafts can be provided and installed on the driven wheel respectively to form the double-headed eccentric shaft 6.

[0119] Example 3

[0120] 13 to 17 , a body relaxation adjustment device according to a third embodiment of the present invention is shown. The body relaxation adjustment device includes:

[0121] Base 1;

[0122] a motor 2, mounted on the base 1;

[0123] Two left and right human body support components 5, the two human body support components 5 are arranged on the base 1 so as to swing up and down alternately with the horizontal plane as the center;

[0124] Pulley assembly 31;

[0125] A double-ended eccentric shaft 6 is connected to the driven pulley of the pulley assembly 31;

[0126] Two sets of connecting components are rotatably connected to the double-headed eccentric shaft 6 and the human body supporting component 5. The structure of the connecting components can refer to the description of the above embodiment.

[0127] The third embodiment differs from the second embodiment primarily in the connection frame 30 fixedly connected to the body support assembly 5. In this embodiment, the connection frame 30 is U-shaped, having only a vertical portion 301 perpendicular to the body support assembly 5 and no extended portion 302. The vertical portion 301 is rotatably connected to the connection member 34 via a second shaft 37.

[0128] Example 4

[0129] 18 to 20 , a body relaxation adjustment device according to a fourth embodiment of the present invention includes:

[0130] Base 1;

[0131] a motor 2, mounted on the base 1;

[0132] Two left and right human body support components 5, the two human body support components 5 are arranged on the base 1 so as to swing up and down alternately with the horizontal plane as the center;

[0133] Pulley assembly 31;

[0134] A double-ended eccentric shaft 6 is connected to the driven pulley of the pulley assembly 31;

[0135] Two groups of connection components, each of which includes a connection piece 34 rotatably connected to the double-headed eccentric shaft 6 and the human body support component 5.

[0136] In this embodiment, the swing axes of the two human body support components 5 are coaxially arranged and located at the ends in the front-to-back direction (usually the toes). When in use, the human body will swing slightly in the front-to-back direction during the up-and-down swing, unlike the previous embodiment in which the human body swings slightly left-to-right during the up-and-down swing.

[0137] In this embodiment, the connecting assembly includes a connecting member 34 , a first bearing 36 , a second shaft 37 , a second bearing 38 , a pressing piece 39 , and a connecting frame 30 .

[0138] In this embodiment, the connecting frame 30 of the connecting assembly has a U-shaped body and an opening extending through the U-shaped body. The connecting frame 30 is fixed to the body support assembly 5 via screws. The body support assembly 5 has multiple screw holes extending in the front-to-back direction. The base also has multiple sets of screw holes in the front-to-back direction for mounting the motor 2 and the seat bearing 32. By moving the motor 2, seat bearing 32, pulley assembly 31, double-ended eccentric shaft 6, and connecting assembly as a whole, the vertical swing amplitude of the body support assembly 5 can be easily adjusted. Furthermore, during use, the user can choose to stand at different positions in the front-to-back direction of the body support assembly 5 to achieve the desired amplitude.

[0139] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
