[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0041] It should be noted that when a component is referred to as being "connected" to another component, it can be directly connected to the other component or there may also be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments, and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0043] As Figures 1 to 7 shown, the present application provides a massage chair 100 for dynamically allocating the rhythm feeling intensity of multiple body parts based on the frequency change, and the rhythm frequency applied to the user does not exceed 40 Hz; the massage chair 100 includes a chair frame 10, a rhythm module 20 and an electronic control module. The chair frame 10 is adapted to support the user in a lying posture; the rhythm module 20 includes a motor 21 and a transmission mechanism 22 that restricts the chair frame 10 to move up and down rhythmically. The motor 21 is power-connected to the chair frame 10 via the transmission mechanism 22; the electronic control module applies a rhythm frequency change signal 101 to the motor 21 and drives the chair frame 10 to execute a rhythm feeling intensity dynamic allocation mode through the motor 21; wherein, the rhythm feeling intensity dynamic allocation mode is to dynamically allocate the rhythm feeling intensity among multiple body parts of the user based on the rhythm frequency change signal 101.

[0044] When the user sits on the chair frame 10 for massage, the chair frame 10 drives the user to move up and down rhythmically, which can achieve the effect of massaging the whole body of the user. Moreover, the rhythm frequency change signal 101 enables the motor 21 to drive the chair frame 10 to execute the rhythm feeling intensity dynamic allocation mode, so as to be able to change the rhythm intensity of different body parts of the user and perform massage actions on different body parts of the user specifically.

[0045] In this embodiment, as Figures 1 to 3As shown, the chair frame 10 includes a seat 11 and a backrest 12. The user's buttocks can be placed on the seat 11, and the user's back can lean against the backrest 12. The angle between the seat 11 and the backrest 12 is approximately 100 degrees - 140 degrees, so that the chair frame 10 can be used in a lying position. Among them, if the angle between the seat 11 and the backrest 12 is too large or too small, it will affect the comfort of the user when using the chair frame 10. Preferably, the angle between the seat 11 and the backrest 12 is approximately 110 degrees - 130 degrees. Among them, the angle between the seat 11 and the backrest 12 is fixedly set.

[0046] The angle between the seat 11 and the backrest 12 is the angle between the surface of the seat 11 facing the user and the surface of the backrest 12 facing the user. The surfaces of the seat 11 facing the user and the backrest 12 facing the user may not be regular flat surfaces. For example, the seat 11 and the backrest 12 can be curves that fit the user's buttocks and back. Therefore, the angle between the seat 11 and the backrest 12 needs to be defined by the effective support area when they contact the human body. Among them, the effective support area can be approximately regarded as an assumed plane to facilitate the confirmation of the angle between the seat 11 and the backrest 12.

[0047] In this embodiment, as Figures 1 to 3 shown, the up-and-down rhythm of the chair frame 10 is that the chair frame 10 moves upward by a certain amplitude and downward by a certain amplitude, and then moves at a certain frequency. Among them, when the chair frame 10 moves upward, it can be understood that the chair frame 10 moves upward along the direction of gravity. When the chair frame 10 moves downward, it can be understood that the chair frame 10 moves downward along the direction of gravity.

[0048] In this embodiment, the electronic control module can adopt existing technologies and will not be further elaborated here. For example, the electronic control module is a single-chip microcomputer or the like.

[0049] In this embodiment, the displacement range of the up-and-down rhythm of the chair frame 10 is 1.0 mm - 3.0 mm. When the displacement range of the up-and-down rhythm of the chair frame 10 is too small, the massage effect cannot be achieved. When the displacement range of the up-and-down rhythm of the chair frame 10 is too large, the frequency of the up-and-down rhythm of the chair frame 10 is not easy to be too high. If the frequency of the up-and-down rhythm of the chair frame 10 is too high, it will cause discomfort to the user when using the rhythmic massage chair 100. Among them, the displacement of the up-and-down rhythm of the chair frame 10 is the sum of the displacement of the chair frame 10 moving upward and the displacement of the chair frame 10 moving downward.

[0050] After multiple experimental demonstrations, the displacement and frequency of the up-and-down rhythm of the chair frame 10 are coordinated to provide a better massage effect for the user. When the frequency of the up-and-down rhythm of the chair frame 10 does not exceed 40 Hz; the displacement range of the up-and-down rhythm of the chair frame 10 is 1 mm to 3.0 mm, and at this time, when the chair frame 10 makes an up-and-down rhythm, the massage effect is the best. If the displacement of the up-and-down rhythm of the chair frame 10 is too large, it will bring the risk of impact to the user's internal organs; if the displacement of the up-and-down rhythm of the chair frame 10 is too small, when the frequency of the up-and-down rhythm is too high, it cannot form an effective rhythmic massage for the user. Preferably, the displacement range of the up-and-down rhythm of the chair frame 10 is 1.5 mm - 2.5 mm, and at this time, when the chair frame 10 makes an up-and-down rhythm, the massage effect is the best. Within this rhythm displacement range, when the frequency of the up-and-down rhythm of the chair frame 10 is 1 Hz - 14 Hz, the rhythmic massage effect is better. Further preferably, the displacement range of the up-and-down rhythm of the chair frame 10 is 2 mm.

[0051] In this embodiment, the rhythm frequency change signal 101 includes a first frequency and a second frequency, and the difference between the first frequency and the second frequency is not less than 3 Hz. When the chair frame 10 makes a rhythm switch from the first frequency to the second frequency, it can change the rhythm-enhanced part of the user. This adjustment mechanism is based on the differences in the biomechanical properties of human tissues: the subcutaneous fat layer and skeletal muscle tissue exhibit different energy dissipation characteristics during the vibration transmission process, resulting in different resonance responses of the vibration wave in the fat-rich area and the muscle-dominated area.

[0052] After the first frequency runs for the first period, it quickly switches to the second frequency at intervals of the second period. The first period is not less than 3S, and the second period is not more than 3S. Among them, when the first period is small, the rhythm-enhanced part of the human body cannot achieve the massage effect. When the second period is too large, the chair frame 10 switches from the first frequency to the second frequency relatively slowly. Preferably, the first period is not less than 5S, and the second period is not more than 2S.

[0053] In this embodiment, when the rhythm frequency is configured between 5 Hz and 8 Hz, it can increase the rhythm intensity of the user's abdomen. Clinical biomechanical experiments show that: when the rhythm frequency is set in the range of 5 Hz - 8 Hz, the resonance response in the abdominal area of the human body reaches the peak, and at this time, the user can perceive the strongest rhythmic stimulation.

[0054] When the rhythm frequency is below 5 Hz, although the rhythm of the abdomen is strong, the vibration period of the abdomen is too long, resulting in a significant attenuation of the vibration energy in the subcutaneous fat layer, and the user can only perceive a weak deep vibration stimulation. When the rhythm frequency is above 8 Hz, when the chair frame drags the user to the highest point, the abdomen is at the highest point at this time; when the chair frame drags the user to the lowest point, the abdomen may not have fallen to the lowest point yet. This non-synchronous movement causes a lagging deformation of the fat layer, directly resulting in an exponential attenuation of the rhythm perception intensity.

[0055] In this embodiment, as Figure 7 shown, the rhythm frequency change signal includes a frequency increase signal in which the rhythm frequency gradually increases to the first set frequency 102, and a frequency mutation signal in which the frequency suddenly changes from the first set frequency 102 to the second set frequency 103. The second set frequency 103 is more than 5 Hz less than the first set frequency 102. The user lies on the chair frame 10. After the chair frame 10 moves at the first set frequency 102 for a period of time, the chair frame 10 switches to the second set frequency 103 for rhythm. At this time, the cells in the human body switch from the shaking speed, and can massage the inside of the user's body, so as to make the user feel relaxed and further strengthen the massage of the whole body. Among them, when the difference between the frequency of the first set frequency 102 and the second set frequency 103 is small, the difference between the rapid shaking and the slow shaking of the cells in the human body is not obvious, and the effect of massaging the inside of the user's body is poor. Among them, the lower the second set frequency 103 is relative to the first set frequency 102, the more obvious the feeling of the cells in the human body switching from rapid shaking to slow shaking is.

[0056] In this embodiment, as Figure 7 shown, the time period for the sudden change from the first set frequency 102 to the second set frequency 103 is not more than 3 s. The user lies on the chair frame 10. When the chair frame 10 suddenly switches from the first set frequency 102 to the second set frequency 103, the cells in the human body switch from rapid shaking to slow shaking. Among them, after the first set frequency 102 runs for a period of time in the first time period T1, it will switch to the second set frequency 103 after the second time period T2. Among them, the first time period T1 is greater than 3 seconds. When the first time period T1 is small, the cells in the human body may not be able to achieve the effect of rapid shaking. When the second time period T2 is too large, the chair frame 10 switches from the first set frequency 102 to the second set frequency 103 rhythmically and slowly, and cannot make the cells in the human body switch from rapid shaking to slow shaking.

[0057] In this embodiment, the frequency increase signal is configured to increase the rhythm frequency step by step to the first set frequency 102; among them, the rhythm difference between adjacent levels is not more than 5.0 Hz, and the duration of each level of rhythm is not less than 1 s, so as to be able to increase the rhythm frequency stably to the first set frequency 102, so as to enable the user's body to have sufficient adaptation time and reduce the physiological rejection reaction caused by frequency jump. If the increase of each level of frequency is too large, the increase of the rhythm frequency is unstable. If the duration of each level of frequency is too short, the user will not have sufficient adaptation time. Preferably, the duration of each level of frequency is not less than 3 s.

[0058] In this embodiment, the rhythm of the chair frame includes multiple gears, and the frequencies of each gear are respectively: the range of the first gear frequency is 3.5 Hz - 4.5 Hz; the range of the second gear frequency is 5.5 Hz - 6.5 Hz; the range of the third gear frequency is 6.5 Hz - 7.5 Hz; the range of the fourth gear frequency is 7.5 Hz - 8.5 Hz; the range of the fifth gear frequency is 9 Hz - 10 Hz; the range of the sixth gear frequency is 10 Hz - 11 Hz; the range of the seventh gear frequency is 11.5 Hz - 12.5 Hz.

[0059] The first frequency, the second frequency, the first set frequency 102, the second set frequency 103, and the frequencies of each level can all adopt the corresponding frequency gears as described above, as long as the requirements of the first frequency, the second frequency, the first set frequency 102, the second set frequency 103, and the frequencies of each level are met. Among them, there is at least a difference of three gears between the first set frequency 102 and the second set frequency 103.

[0060] Preferably, the range of the first gear frequency is 4.0 Hz–4.3 Hz; the range of the second gear frequency is 5.8 Hz–6.2 Hz; the range of the third gear frequency is 7.0 Hz–7.3 Hz; the range of the fourth gear frequency is

[0061] 8.2 Hz–8.4 Hz; the range of the fifth gear frequency is 9.4 Hz–9.6 Hz; the range of the sixth gear frequency is 10.5 Hz–10.8 Hz; the range of the seventh gear frequency is 11.7 Hz–11.9 Hz. Specifically, the first gear frequency is 4.17 Hz; the second gear frequency is 6 Hz; the frequency of the third gear level is 7.17 Hz; the frequency of the fourth gear level is 8.33 Hz; the frequency of the fifth gear level is 9.5 Hz; the frequency of the sixth gear level is 10.67 Hz; the frequency of the seventh gear level is 11.83 Hz.

[0062] In this embodiment, as Figures 1 to 6 shown, the massage chair 100 further includes a fixed seat 30 and a load-bearing seat 40. The load-bearing seat 40 is configured to be able to rhythmically move up and down relative to the fixed seat 30. The load-bearing seat 40 receives the weight of the user and the chair frame 10 and can drag the user to rhythmically move up and down. The fixed seat 30 is used to contact the ground and can support the massage chair 100; the load-bearing seat 40 is used to receive the weight of the user and the chair frame 10 and is fixedly connected to the machine frame. There are no strict restrictions on the structures of the fixed seat 30 and the load-bearing seat 40; for example, both the fixed seat 30 and the load-bearing seat 40 are frame structures.

[0063] In this embodiment, as Figures 4 to 6As shown, the transmission mechanism 22 includes an eccentric wheel 221. The motor 21 drives the eccentric wheel 221 to rotate, so as to convert the eccentric motion of the eccentric wheel 221 into the up-and-down rhythm of the chair frame 10. The transmission mechanism 22 further includes a drive shaft 223 and a driving wheel 222. Both the driving wheel 222 and the eccentric wheel 221 are arranged on the drive shaft 223. The motor 21 is drivingly connected to the driving wheel 222 through a transmission belt 225, so that the driving wheel 222 drives the drive shaft 223, and the drive shaft 223 drives the eccentric wheel 221 to rotate.

[0064] In this embodiment, as Figures 4 to 6 shown, the motor 21 is installed on a fixed seat 30; the drive shaft 223 is rotatably installed on the fixed seat 30; the driving wheel 222 and the eccentric wheel 221 are arranged at intervals along the axial direction of the drive shaft 223; a bushing 224 is sleeved outside the eccentric wheel 221, and the bushing 224 is rotatably connected to the eccentric wheel 221 and fixed to the load-bearing seat 40. The motor 21 drives the driving wheel 222 through the transmission belt 225, the driving wheel 222 drives the drive shaft 223, the drive shaft 223 drives the eccentric wheel 221, and the eccentric wheel 221 drives the load-bearing seat 40 to move up and down through the bushing 224.

[0065] In this embodiment, as Figures 1 to 5 shown, the included angle between the chair frame 10 and the horizontal direction ranges from 110° to 185°. The chair frame 10 is configured to be able to controllably change its included angle with the horizontal direction, so as to adjust the rhythm perception intensity of different body parts by changing the lying posture of the user; so as to perform focused massage on different parts of the user. Among them, the included angle between the chair frame 10 and the horizontal direction can be understood as: the included angle between the backrest 12 and the horizontal direction. Preferably, the included angle between the chair frame 10 and the horizontal direction ranges from 130° to 185°.

[0066] In this embodiment, as Figure 4 and Figure 5 shown, the massage chair 100 further includes a drive mechanism 50. The drive mechanism 50 is configured to be able to drive the chair frame 10 to rotate, so as to be able to adjust the included angle between the chair frame 10 and the horizontal direction. The drive mechanism 50 includes a cylinder 51. The cylinder 51 is configured to be able to drive the chair frame 10 to swing, so as to be able to adjust the included angle between the backrest 12 and the horizontal direction.

[0067] In this embodiment, as Figure 4 and Figure 5As shown, the air cylinder 51 is installed between the chair frame 10 and the load-bearing seat 40; the rhythmic massage chair 100 further includes a swing rod, one end of the swing rod is rotatably connected to the chair frame 10, and the other end is rotatably connected to the load-bearing seat 40; when the air cylinder 51 is pushed, the chair frame 10 swings through the swing rod. Among them, the chair frame 10 has a connecting rod 52, the connecting rod 52 is rotatably connected to the chair frame 10, and rollers 53 are respectively arranged at both ends of the connecting rod 52; the load-bearing seat 40 has a chute 54 for the rollers 53 to slide; one end of the air cylinder 51 is connected to the load-bearing seat 40, and the other end is connected to the connecting rod 52. The air cylinder 51 pushes the connecting rod 52, and the rollers 53 at both ends of the connecting rod 52 slide along the chute 54 to be able to push the chair frame 10, and the swing rod between the chair frame 10 and the load-bearing seat 40 swings, so that the chair frame 10 can swing.

[0068] In this embodiment, the massage chair 100 further includes a massage mechanism (not shown in the figure), the massage mechanism is configured on the chair frame 10 and is used to perform massage actions; the massage mechanism is movably installed on the chair frame 10 and can move along the extending direction of the user's body to be able to massage parts such as the user's back.

[0069] In this embodiment, when the chair frame 10 moves rhythmically up and down, the massage mechanism is located at the seat part of the massage chair 100 so that the massage mechanism can be located below the user's buttocks and / or lower limbs. When the chair frame 10 moves rhythmically up and down and the area where the massage mechanism is located is not appropriate, it will cause the user to have a sense of something being placed, resulting in discomfort for the user; the massage mechanism being able to be located below the user's buttocks and / or lower limbs can effectively reduce the user's sense of something being placed. Among them, the massage mechanism can be in the prior art; the structure of the massage mechanism will not be further elaborated.

[0070] In this embodiment, when the chair frame 10 moves rhythmically up and down, the massage mechanism can perform massage actions on the user's back or shoulders. The rhythmic up and down movement of the chair frame 10 drags the user to perform a rhythmic up and down movement in the vertical direction. The rhythmic up and down movement changes the force between the user's back and the backrest 12. Since the massage mechanism massages the user at the same time, the user's own gravity falls back and impacts the massage head on the massage machine, enhancing the massage intensity, so that the massage intensity of the massage head can penetrate deeper into the human muscle tissue, thereby improving the massage effect and comfort of the massage chair.

[0071] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification. When the technical features in different embodiments are reflected in the same drawing, it can be regarded that the drawing also discloses the combined examples of the respective embodiments involved at the same time.

[0072] The above embodiments only represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several variations and improvements can still be made, and these all fall within the protection scope of the present application.
