Description

Technical Field

[0001] This invention relates to the field of massage chair technology, and more particularly to an integrated massage chair. Background Technology

[0002] Modern office workers commonly face the problem of prolonged sitting and desk work. As the main weight-bearing part, the buttocks bear the body weight continuously during long periods of sitting, causing local muscle tissue to be in a state of tension, hindering blood circulation, and easily leading to fatigue such as soreness and stiffness. At the same time, when working at a desk, the forearms need to be continuously supported on the table to maintain the operating posture, while the shoulders remain in a fixed abducted or flexed position, causing the forearm muscles and shoulder ligaments to be in a state of tension for a long time, resulting in discomfort such as soreness and limited mobility. These problems seriously affect the physical comfort and work efficiency of office workers.

[0003] Most existing massage chairs are designed with full-body massage or massage of single areas such as the lower back and buttocks as their core design focus, lacking effective solutions for shoulder and forearm fatigue problems in office settings: most products do not have a dedicated forearm massage structure, and can only provide support through simple hand placement positions, failing to provide targeted massage for forearm muscles; more importantly, existing technology generally ignores the needs of shoulder movement, and does not have a shoulder movement mechanism designed in conjunction with massage movements, failing to assist the shoulder movement to relieve stiffness during the massage, and generally only massages the user's back and legs, lacking massage for the user's buttocks, so the massage effect cannot make the user relax the whole body. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide an integrated massage chair to solve the problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution: an integrated massage chair, including a seating mechanism, on both sides of the seating mechanism are symmetrically distributed buttock massage mechanisms and transmission mechanisms, and on both sides of the seating mechanism are symmetrically distributed forearm massage mechanisms.

[0007] Preferably, one side of the dual-head reducer is fixedly connected to both inner sides of the lower end of the seating frame, and the other side of the optocoupler sensor plate is fixedly connected to the upper end of the dual-head reducer.

[0008] Preferably, each of the transmission mechanisms includes an L-shaped support frame, with a drive shaft rotatably connected to the lower inner part of each L-shaped support frame. One end of each drive shaft is fixedly connected to a driven pulley, and each driven pulley is connected to a drive pulley and a tension pulley via a transmission belt. A limit shaft is rotatably connected to the middle of each tension pulley, and a sliding block is fixedly connected to the other end of each limit shaft. A connecting shaft is fixedly connected to the middle of each sliding block, and an L-shaped toothed plate is fixedly connected to one end of each connecting shaft. An adjusting gear is meshed with the upper end of each L-shaped toothed plate.

[0009] Preferably, the lower ends of the L-shaped support frames are all fixedly connected to the lower inner rear side of the base bracket, the middle inner circumference of the drive pulley is fixedly connected to the middle outer circumference of one drive end of the double-head reducer, and the middle inner circumference of the adjusting gear is fixedly connected to the middle outer circumference of the rotating shaft.

[0010] Preferably, the outer periphery of the middle portion of the limiting shaft is slidably connected to the opening on one side of the upper end of the L-shaped support frame, and the outer periphery of the middle portion of the connecting shaft is slidably connected to the opening on the other side of the L-shaped support frame.

[0011] Preferably, the outer periphery of the sliding block is slidably connected to the upper opening of the L-shaped support frame, and one side of the L-shaped toothed plate is slidably connected to the upper inner sides of the bottom bracket.

[0012] Preferably, each of the forearm massage mechanisms includes a support base, a sliding seat slidably connected to the upper inner part of the support base, a forearm seat fixedly connected to the upper end of the sliding seat, a double-threaded screw threaded to the lower end of the sliding seat, a driven bevel gear fixedly connected to the lower end of the double-threaded screw, a driving bevel gear meshing with the lower end of the driven bevel gear, a splined shaft slidably connected to the upper opening of the double-threaded screw, a worm gear fixedly connected to the upper end of the splined shaft, worm wheels meshing with both sides of the upper end of the worm gear, a rotating rod fixedly connected to the middle of the worm wheel, and triangular plates evenly distributed on the outer periphery of the rotating rod.

[0013] Preferably, one side of each support base is fixedly connected to the upper ends of both sides of the base bracket, and the middle part of each drive bevel gear is fixedly connected to the outer periphery of the middle part of the drive shaft.

[0014] Preferably, the outer periphery of the middle part of the worm gear is rotatably connected to the lower rear opening of the forearm seat, and the front and rear ends of the rotating rod are rotatably connected to the inner rear side of the forearm seat.

[0015] The integrated massage chair provided by this invention has the following beneficial effects:

[0016] 1. By starting the motor, the cam rotates via the double-head reducer, which in turn drives the massage seat to vibrate up and down around the rotating seat via the adjusting rod. Simultaneously, when the circular encoder passes through the optical coupler sensor plate, the distance between the upper and lower circular holes of the encoder is different. After the optical coupler sensor plate detects whether the light passes through, it identifies whether the positions of the upper and lower circular holes of the encoder on both sides are consistent and transmits the electrical signal to the controller to determine the movement status of the massage seats on both sides, thereby controlling the start and stop status of the motor. Through the cooperation of the circular encoder and the optical coupler sensor plate, it can identify whether the left and right massage seats are in a state of synchronous lifting or alternating lifting. The buttock massage mechanism vibrates the user's buttocks, achieving the effect of massaging the user's buttocks. When the massage seats on both sides rise and fall, they sway the user's buttocks, achieving the effect of relaxing the user's buttocks and relieving the fatigue of the user's buttocks from long-term office work.

[0017] 2. When the dual-head reducer drives the cams and circular encoders on both sides to rotate, the driven pulley rotates through the cooperation of the drive pulley, transmission belt, and tension pulley. This, in turn, drives the double-sided threaded screw to rotate through the drive bevel gear and driven bevel gear. Consequently, the forearm seat moves downwards when the massage seat on the same side rises, and rises when the massage seat on the same side falls. Simultaneously, the double-sided threaded screw drives the worm gear to rotate through the spline shaft, which in turn drives the rotating rods on both sides to rotate through the worm wheel. This, in turn, causes the triangular plates to rotate, gradually moving all the protrusions of the triangular plates to the outside of the upper opening of the forearm seat, thus massaging the user's forearm. Through the cooperation of the transmission mechanism and the forearm massage mechanism, the user's shoulders and forearms are massaged simultaneously while the user's buttocks are being massaged, further relieving the discomfort caused by the user's shoulders and forearms being supported on the desk for a long time while working.

[0018] 3. When the linear motor adjusts the angle of the seating frame, the rotating shaft drives the adjusting gear to rotate, which in turn drives the sliding block to slide inside the L-shaped support frame via the connecting shaft. Then, the height of the tension belt pulley is adjusted via the limit shaft. This ensures that when the position of the double-headed reducer changes with the rotation of the seating frame, the tension belt pulley can stably tension the transmission belt. Through the transmission mechanism, the buttock massage mechanism can always drive the forearm massage mechanism to massage the user's forearm and perform shoulder exercises when the linear motor adjusts the angle of the seating frame.

[0031] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0032] like Figures 1-10 As shown, this embodiment proposes an integrated massage chair, including a seating mechanism 1. A hip massage mechanism 2 and a transmission mechanism 3 are symmetrically distributed on both inner sides of the seating mechanism 1. A forearm massage mechanism 4 is symmetrically distributed on both sides of the seating mechanism 1. Each hip massage mechanism 2 includes a motor 21. A double-head reducer 22 is fixedly connected to the rear drive end of the motor 21. A cam 25 is fixedly connected to one drive end of the double-head reducer 22. An adjustment rod 26 is rotatably connected to the lower end of the cam 25. A massage seat 27 is rotatably connected to the upper end of the adjustment rod 26. The front end of the massage seat 27 is rotatably connected to the upper front end of the seating frame 13 via a rotating seat 3 28. A circular encoder 23 is fixedly connected to the other drive end of the double-head reducer 22. An optocoupler sensor plate 24 is rotatably connected to the upper end of the circular encoder 23.

[0033] In this embodiment, the seating mechanism 1 includes a base support 11 and a seating frame 13. The upper ends of the base support 11 are rotatably connected to the two sides of the base. The ends of the rotating shafts 12 away from the base support 11 are fixedly connected to the lower middle part of the seating frame 13. The upper rear side of the seating frame 13 is fixedly connected to the back support pad 14. The upper front side of the base support 11 is rotatably connected to the linear motor 16 through a rotating seat 15. The upper drive end of the linear motor 16 is rotatably connected to the lower front side of the seating frame 13 through a rotating seat 2 17.

[0034] In this embodiment, one side of the dual-head reducer 22 is fixedly connected to the inner sides of the lower end of the seat frame 13, and the other side of the optocoupler sensing plate 24 is fixedly connected to the upper end of the dual-head reducer 22.

[0035] Specifically, when a user uses the massage chair, the controller activates the linear motor 16. Through the cooperation of rotating seats 15 and 17, the seating frame 13 rotates around the pivot 12 at the upper end of the base support 11, allowing the user to lie flat. The motor 21 is then activated, driving the cam 25 to rotate via the double-head reducer 22. This, in turn, drives the massage seat 27 to vibrate up and down around the rotating seat 28 via the adjusting rod 26. Simultaneously, when the circular holes at the upper and lower ends of the circular encoder 23 pass through the photocoupler sensor 24, the distance between the upper and lower holes from the center of the circular encoder 23 is different, and the photocoupler sensor 24 detects the light. If the test fails, the system identifies whether the positions of the upper and lower circular holes on both sides of the circular encoder 23 are consistent and transmits the electrical signal to the controller to determine the movement state of the massage seats 27 on both sides. This determines the start and stop state of the motor 21. Through the cooperation of the circular encoder 23 and the optocoupler sensor board 24, the system can identify whether the left and right massage seats 27 are in a state of synchronous lifting or alternating lifting. The hip massage mechanism 2 will vibrate the user's hips to massage the user's hips. When the massage seats 27 on both sides lift and lower, they will sway the user's hips to relax the user's hips and relieve the fatigue of the user's hips from long-term office work.

[0036] In this embodiment, each transmission mechanism 3 includes an L-shaped support frame 31. The lower inner part of the L-shaped support frame 31 is rotatably connected to a drive shaft 32. One end of the drive shaft 32 is fixedly connected to a driven pulley 33. The driven pulley 33 is connected to a drive pulley 35 and a tension pulley 36 via a transmission belt 34. The middle part of the tension pulley 36 is rotatably connected to a limit shaft 37. The other end of the limit shaft 37 is fixedly connected to a sliding block 38. The middle part of the sliding block 38 is fixedly connected to a connecting shaft 39. One end of the connecting shaft 39 is fixedly connected to an L-shaped toothed plate 310. The upper end of the L-shaped toothed plate 310 is meshed with an adjusting gear 311.

[0037] In this embodiment, the lower ends of the L-shaped support frame 31 are all fixedly connected to the lower inner rear side of the base bracket 11, the middle inner circumference of the drive pulley 35 is all fixedly connected to the middle outer circumference of one side drive end of the double-head reducer 22, and the middle inner circumference of the adjusting gear 311 is all fixedly connected to the middle outer circumference of the rotating shaft 12.

[0038] In this embodiment, the outer periphery of the middle part of the limiting shaft 37 is slidably connected to the upper side opening of the L-shaped support frame 31, and the outer periphery of the middle part of the connecting shaft 39 is slidably connected to the other side opening of the L-shaped support frame 31.

[0039] In this embodiment, the outer periphery of the sliding block 38 is slidably connected to the upper opening of the L-shaped support frame 31, and one side of the L-shaped toothed plate 310 is slidably connected to the upper ends of the inner two sides of the bottom bracket 11.

[0040] Specifically, when the linear motor 16 adjusts the angle of the seating frame 13, it drives the adjusting gear 311 to rotate via the rotating shaft 12. This, in turn, drives the sliding block 38 to slide inside the L-shaped support frame 31 via the connecting shaft 39. Furthermore, the height of the tension pulley 36 is adjusted via the limiting shaft 37. As the position of the double-headed reducer 22 changes with the rotation of the seating frame 13, the tension pulley 36 can stably tension the transmission belt 34. Through the transmission mechanism 3, the buttock massage mechanism 2 can always drive the forearm massage mechanism 4 to massage the user's forearm and perform shoulder exercises while the linear motor 16 adjusts the angle of the seating frame 13.

[0041] In this embodiment, each forearm massage mechanism 4 includes a support base 41. A sliding seat 42 is slidably connected to the upper inner part of the support base 41. A forearm seat 43 is fixedly connected to the upper end of the sliding seat 42. A bidirectional threaded screw 44 is threadedly connected to the lower end of the sliding seat 42. A driven bevel gear 45 is fixedly connected to the lower end of the bidirectional threaded screw 44. A driving bevel gear 46 is meshed with the lower end of the driven bevel gear 45. A splined shaft 47 is slidably connected to the upper opening of the bidirectional threaded screw 44. A worm gear 48 is fixedly connected to the upper end of the splined shaft 47. Worm wheels 49 are meshed with both sides of the upper end of the worm gear 48. A rotating rod 410 is fixedly connected to the middle of the worm wheel 49. Triangular plates 411 are evenly distributed on the outer periphery of the rotating rod 410.

[0042] In this embodiment, one side of the support base 41 is fixedly connected to the upper ends of both sides of the base bracket 11, and the middle part of the drive bevel gear 46 is fixedly connected to the outer periphery of the middle part of the drive shaft 32.

[0043] In this embodiment, the outer periphery of the middle part of the worm gear 48 is rotatably connected to the lower rear opening of the forearm seat 43, and the front and rear ends of the rotating rod 410 are rotatably connected to the inner rear side of the forearm seat 43.

[0044] Specifically, when the dual-head reducer 22 drives the cams 25 and the circular encoder 23 on both sides to rotate, the driven pulley 33 is driven to rotate through the cooperation of the drive pulley 35, the transmission belt 34 and the tension pulley 36. This, in turn, drives the bidirectional threaded screw 44 to rotate through the drive bevel gear 46 and the driven bevel gear 45. Consequently, the forearm seat 43 is driven to descend when the massage seat 27 on the same side rises, and rises when the massage seat 27 on the same side descends. At the same time, the bidirectional threaded screw 44 drives the forearm seat 43 through the splined shaft 47 to rotate. The worm gear 48 rotates, which in turn drives the rotating rods 410 on both sides to rotate via the worm wheel 49. This, in turn, causes the triangular plates 411 to rotate, so that the protrusions of all the triangular plates 411 gradually rotate to the outside of the upper opening of the forearm seat 43, thus massaging the user's forearm. Through the cooperation of the transmission mechanism 3 and the forearm massage mechanism 4, the user's shoulders can be massaged while the user's buttocks are being massaged, and the user's forearm can also be massaged at the same time, further relieving the discomfort caused by the user's shoulders and forearms being supported on the desk for a long time while working.

[0045] Working principle: When a user uses the massage chair, the controller starts the linear motor 16. Through the cooperation of rotating seats 15 and 17, the seating frame 13 rotates around the pivot 12 on the upper end of the base support 11, allowing the user to lie flat. The motor 21 is then started, driving the cam 25 to rotate via the double-head reducer 22. This, in turn, drives the massage seat 27 to vibrate up and down around the rotating seat 28 via the adjusting rod 26. Simultaneously, when the circular holes at the upper and lower ends of the circular encoder 23 pass through the photocoupler sensor 24, the distance between the upper and lower holes from the center is different. The photocoupler sensor 24 detects whether light has passed through, identifies whether the positions of the upper and lower holes on both sides of the circular encoder 23 are consistent, and transmits an electrical signal to... The controller determines the movement state of the massage seats 27 on both sides and controls the start and stop state of the motor 21. Through the cooperation of the circular encoder 23 and the optocoupler sensor board 24, it can identify whether the left and right massage seats 27 are in a state of synchronous lifting or alternating lifting. The buttock massage mechanism 2 will vibrate the user's buttocks to massage the user's buttocks. When the massage seats 27 on both sides rise and fall, they will sway the user's buttocks to relax the user's buttocks and relieve the fatigue of the user's buttocks from long-term office work. When the double-head reducer 22 drives the cams 25 on both sides and the circular encoder 23 to rotate, through the cooperation of the drive pulley 35, the transmission belt 34 and the tension pulley 36, the driven pulley 33 is driven to rotate, thereby driving the motor 21 to rotate. The moving bevel gear 46 and the driven bevel gear 45 drive the bidirectional threaded screw 44 to rotate, which in turn drives the forearm seat 43 to descend when the massage seat 27 on the same side rises, and the forearm seat 43 to rise when the massage seat 27 on the same side descends. Simultaneously, the bidirectional threaded screw 44 drives the worm gear 48 to rotate via the splined shaft 47, which in turn drives the rotating rods 410 on both sides to rotate via the worm wheel 49. This, in turn, causes the triangular plates 411 to rotate, so that the protrusions of all the triangular plates 411 gradually rotate to the outside of the upper opening of the forearm seat 43, massaging the user's forearm. Through the cooperation of the transmission mechanism 3 and the forearm massage mechanism 4, it is possible to massage the user's buttocks, shoulder area, and forearm simultaneously. To alleviate the discomfort caused by prolonged support of the shoulders and forearms on the desk during office work, the linear motor 16 adjusts the angle of the seating frame 13, driving the adjusting gear 311 to rotate via the rotating shaft 12. This, in turn, drives the sliding block 38 to slide inside the L-shaped support frame 31 via the connecting shaft 39. Furthermore, the height of the tension pulley 36 is adjusted via the limiting shaft 37. As the position of the double-headed reducer 22 changes with the rotation of the seating frame 13, the tension pulley 36 can stably tension the transmission belt 34. Through the transmission mechanism 3, the hip massage mechanism 2 can always drive the forearm massage mechanism 4 to massage the user's forearm and provide shoulder exercises while the linear motor 16 adjusts the angle of the seating frame 13.

[0046] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
