Description

Technical Field

[0001] This invention relates to the field of massage chair system technology, and more specifically to a folding structure for a massage chair. Background Technology

[0002] Massage chairs, as tools for relieving work fatigue, achieve a massage effect through mechanical rolling and squeezing, which can unblock meridians, promote blood circulation, and maintain the body's yin-yang balance. After use, they can relax muscles, improve joint flexibility, boost spirits, and eliminate fatigue, playing an important role in physical health.

[0003] Existing massage chairs are typically large and occupy significant public space. Therefore, folding structures are often used for storage. Some folding massage chairs already exist, such as the "Folding Massage Chair Structure" disclosed in patent number CN208693718U and the "Novel Structure Massage Chair" disclosed in CN203970816U, all of which improve storage convenience through folding. However, when massage chairs are used in public spaces, the more pressing need is to minimize their footprint when not in use, reducing their encroachment on the surrounding limited horizontal public space without moving them, rather than simply relying on folding for easy transport or storage. Existing folding structures still have significant limitations in such application scenarios.

[0004] Furthermore, existing folding massage chairs typically rely on a power unit to drive the folding process. If users leave personal belongings (such as backpacks, mobile phones, clothing, etc.) behind when leaving, the folding action may pinch or damage these items, posing a safety hazard. Additionally, in certain emergencies, such as an unexpected power outage, massage chairs with shoulder and neck massage mechanisms can easily become mechanically locked to the seat cushion, restricting the user's ability to disembark and affecting safety and user experience.

[0005] Therefore, there is an urgent need to develop a folding structure for massage chairs that can improve safety while saving space through folding. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a massage chair to solve the aforementioned problems.

[0007] This invention provides the following technical solution: A folding structure for a massage chair, comprising: The main body of the massage chair has a support base. The seat cushion is rotatably connected to the support via a pivot, and the pivot is rotated relative to the support and reset by a first return spring. The support frame includes a base and a bracket; the lower end of the bracket is rotatably connected to the base, and the upper end is hinged to the main body of the massage chair; a telescopic device is provided between the bracket and the main body of the massage chair, and a first rotating column is provided on the upper part of the bracket; The swing rod has one end connected to the rotating shaft and the other end connected to one end of the connecting rod; the other end of the connecting rod has a clearance groove along its length, and the first rotating column moves within the corresponding clearance groove.

[0008] Preferably, the massage chair body includes an integral backrest and legs, with an obtuse angle between the backrest and legs; the support is located in the area of ​​the backrest near the legs.

[0009] Preferably, the telescopic device has at least two states when it extends or retracts: In the first state, the backrest is pushed to rotate to an upright position. During this process, the first return spring pushes the pivot to rotate relative to the support and reset, causing the seat cushion to rotate towards the backrest. In the second state, the backrest is pushed to rotate to a reclining position. During this process, the pivot is pushed to rotate through the linkage and swing arm, so that the seat cushion rotates to a horizontal position.

[0010] Preferably, multiple pull ropes are provided between the upper and lower parts of the hollowed-out area in the middle of the backrest.

[0011] Preferably, the lower end of the outrigger is equipped with a movable wheel for rolling on the ground.

[0012] Preferably, a human body sensor is installed on the side of the seat cushion away from the backrest.

[0013] Preferably, the support has an arc-shaped track groove centered on the pivot shaft, and a second rotating column is provided at the connection between the swing rod and the connecting rod, the second rotating column moving within the matching arc-shaped track groove.

[0014] Preferably, the outer side of the massage chair body is provided with a leather cover, and the outer side of the support is provided with a protective shell. The movable parts of the leather cover and the protective shell are respectively provided with a first arc-shaped part and a second arc-shaped part, and the first arc-shaped part and the second arc-shaped part are concentrically arranged with the rotation point of the support relative to the massage chair body as the center.

[0015] Preferably, the upper part of the massage chair body is provided with a shoulder and neck massager.

[0016] Preferably, the head of the massage chair body is equipped with an artificial intelligence interactive device.

[0017] The present invention has the following beneficial technical effects: This invention controls the unfolding or folding of a massage chair through the telescopic control of a telescopic device. During unfolding, the seat cushion is driven to rotate synchronously to a horizontal state through a connecting rod, a swing rod, and a rotating shaft. During folding, the seat cushion is driven to return to its original position by a first return spring, which cooperates with the avoidance groove on the connecting rod to prevent the seat cushion from rotating synchronously, thus avoiding pinching or damage to any items left behind during the seat cushion rotation and folding process.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: A folding structure for a massage chair, such as Figures 1-17 As shown, it includes: Massage chair body 5, such as Figure 3 , Figure 4 , Figure 8 As shown, it includes an integrated backrest 51 and support legs 52, which form an obtuse angle. The lower end of the support legs 52 is equipped with a caster wheel 53 for rolling on the ground. A support 54 is provided at the joint between the backrest 51 and the support legs 52 or at the part of the backrest 51 near the support legs 52. Both the backrest 51 and the support legs 52 are made of steel pipes and other materials, resulting in a hollow center. Multiple pull ropes 55 are provided between the upper and lower parts of the hollow center of the backrest 51, which provide support when the user leans against the backrest 51.

[0022] Support frame 7, such as Figures 3-7As shown, the system includes a base 71 fixed to the ground, a bracket 72 hinged to the base 71 at its lower end, a connecting rod 73, a swing rod 74, a rotating shaft 75, and a second return spring 76. The lower end of the bracket 72 rotates relative to the base 71 within a set angle range. The upper end of the bracket 72 is hinged to the lower middle part of the backrest 51. A telescopic device 4 is connected between the upper part of the bracket 72 and the support leg 52. The telescopic device 4 can be a telescopic cylinder or a hydraulic cylinder, etc. The posture formed between the bracket 72 and the massage chair body 5 is adjusted by the telescopic extension and retraction of the telescopic device 4.

[0023] Under the influence of gravity, the moving wheels 53 at the lower end of the support leg 52 always roll horizontally on the ground. When the telescopic device 4 is extended to the first state, the backrest 51 is vertical relative to the ground, and the moving wheels 53 are close to the base 71. When the telescopic device 4 is extended to the second state, the backrest 51 is slightly tilted backward relative to the ground, and the moving wheels 53 are away from the base 71. This achieves two states for the support frame 7: extended and retracted.

[0024] like Figures 1-7 As shown, the seat cushion 1 is rotatably connected to the support 54 via a pivot 75, and a second return spring 76 is provided between the pivot 75 and the support 54. The elastic force of the second return spring 76 pushes the pivot 75 to rotate relative to the support 54 and return to its original position, so that the seat cushion 1 tends to rotate and fit against the backrest 51. The seat cushion 1 and the pivot 75 are fixedly arranged relative to each other. A swing rod 74 is fixedly arranged on the pivot 75. A second pivot 741 is arranged on the swing rod 74 at a position away from the pivot 75. An arc-shaped track groove 541 centered on the pivot 75 is opened on the support 54. The second pivot 741 slides arc-shapedly in the matching arc-shaped track groove 541. The second rotating column 741 is simultaneously connected to one end of the connecting rod 73. The other end of the connecting rod 73 away from the second rotating column 741 is provided with a relief groove 731. The upper part of the bracket 72 is provided with a first rotating column 723, and the first rotating column 723 slides within the corresponding relief groove 731.

[0025] When the telescopic device 4 is extended to the second state, the backrest 51 tilts slightly backward relative to the ground, and the moving wheel 53 moves away from the base 71. During this process, the distance between the pivot 75 and the first pivot 723 increases. At this time, the first pivot 723 is located near the end of the first pivot 723 in the clearance groove 731 and is limited, thereby driving the swing rod 74 to rotate around the pivot 75 to adapt, so that the seat cushion 1 rotates away from the state of fitting the backrest 51 to a roughly horizontal state.

[0026] When the telescopic device 4 is extended to the first state for storage, the backrest 51 rotates to be vertical relative to the ground, and the moving wheel 53 approaches the base 71. During this process, the distance between the pivot 75 and the first pivot 723 decreases, and the first pivot 723 moves away from the first pivot 723 in the clearance groove 731. Under the elastic force of the second return spring 76, the seat cushion 1 rotates from the horizontal state to fit against the backrest 51. The seat cushion 1 rotates because the elastic force of the second return spring 76 drives it to rotate instead of following the extension and retraction of the telescopic device 4, which can avoid the rigid clamping injury caused by leaving something between the seat cushion 1 and the backrest 51.

[0027] like Figure 9 As shown, a protective shell 721 is provided on the outside of the support 72, which encloses the support 72. A second arc-shaped portion 722 is formed at the upper edge of the protective shell 721. A leather cover 6 is provided on the outside of the massage chair body 5. A back panel 61 is provided on the back of the backrest. A first arc-shaped portion 64 is formed at the lower edge of the back panel 61. The first arc-shaped portion 64 and the second arc-shaped portion 722 are designed to work together and are concentrically designed with the upper end of the support 72 as the center of the hinge point between the upper end of the support 72 and the lower middle part of the backrest 51. This design helps to prevent pinching during the extension and retraction of the telescopic device 4.

[0028] like Figure 9 As shown, the back panel 61 can elastically deform within a small range. The upper end of the back panel 61 is relatively fixed to the leather sleeve 6, and a certain gap is left between the lower end of the back panel 61 and the leather sleeve 6. This gap is maintained by the second elastic element 62, and a second micro switch 63 is provided in the gap. During the extension and retraction of the telescopic device 4, if the back panel 61 collides with an external object while the backrest 51 moves relative to the ground, the gap between the back panel 61 and the leather sleeve 6 will decrease, thereby triggering the second micro switch 63. The second micro switch 63 is triggered and controls the telescopic device 4 to stop and issue an alarm signal to remind the user.

[0029] like Figures 10-14 As shown, the seat cushion 1 includes an upper shell 11 and a lower shell 12. The upper shell 11 is located closer to the backrest 51 than the lower shell 12. The upper shell 11 and the lower shell 12 can slide linearly through the guide post and guide groove. The lower shell 12 is installed on the upper shell 11 by a fixing assembly of elastic screws. A certain movable gap is left between the upper shell 11 and the lower shell 12. Several first elastic elements 14 are provided between the upper shell 11 and the lower shell 12 to keep the movable gap in the maximum state. A first micro switch 15 is provided between the upper shell 11 and the lower shell 12 to monitor whether the movable gap between the upper shell 11 and the lower shell 12 changes. The upper shell 11 has a soft cushion 111 on the side where the user sits (the side closer to the upper shell 11), and the upper shell 11 has a built-in serpentine spring 16 for supporting the soft cushion 111; a control panel 13 for control is installed on the side of the upper shell 11 or the lower shell 12; a human body sensor 8 is installed on the back of the lower shell 12 (the side away from the upper shell 11), and the human body sensor 8 can be a photoelectric sensor, millimeter-wave radar and ultrasonic sensor, etc.

[0030] Normally, the seat cushion 1 is in a vertical position that fits against the backrest 51. At this time, the human body sensor 8 on the back of the seat cushion 1 (lower shell 12) can detect whether anyone is approaching the massage chair.

[0031] During the process of the telescopic device 4 extending and retracting to rotate the seat cushion 1 away from the backrest 51 to a horizontal state, if the seat cushion 1 comes into contact with the outside, the gap between the upper shell 11 and the lower shell 12 will become smaller, thereby triggering the first micro switch 15. The first micro switch 15 is triggered to control the telescopic device 4 to stop through the central processing unit and issue an alarm signal to remind the user.

[0032] like Figure 13 , Figure 14 As shown, the rotating shaft 75 includes a first sleeve 751, an intermediate rod 752, a second sleeve 753, a U-shaped frame 754, and a pipe clamp 755. The U-shaped frame 754 and the pipe clamp 755 are installed in the upper shell 11 by their respective bolts and other fixing components. The U-shaped frame 754 has a non-circular through hole (regular hexagon) through which the intermediate rod 752 passes (relative to the axis of the rotating shaft 75). The two ends of the intermediate rod 752 are non-circular ends adapted to the non-circular through hole, and the middle is a circular cylinder with a small outer diameter. The inner diameter of the second sleeve 753 is the same as that of the middle part of the intermediate rod 752. The outer diameter of the first sleeve 751 is adapted to the outer diameter of the circular cylinder, the outer diameter of the second sleeve 753 is adapted to the inner diameter of the pipe clamp 755, the inner cavity of the first sleeve 751 is adapted to the non-circular end of the right end of the intermediate rod 752, the first sleeve 721 is rotatably connected to the support 54 through a bushing, etc., and one end of the swing rod 74 is fixed to the outer wall of the first sleeve 721; pin holes 756 are provided on both the non-circular end of the right end of the intermediate rod 752 and the first sleeve 721, and the pin is inserted into the pin holes 756 of the non-circular end of the right end of the intermediate rod 752 and the first sleeve 721 to fix the two together. The pipe clamp 755 presses and fixes the second sleeve 753 inside the upper shell 11 with bolts and other fixing components, and is located inside the U-shaped frame 754; the non-circular end of the left end of the intermediate rod 752 passes through the non-circular through hole of the U-shaped frame 754 and the second sleeve 753. At this time, the intermediate rod 752 can move relative to the other end along its axis, and the non-circular end of the right end of the intermediate rod 752 is inserted into the first sleeve 751; then the clamping screw on the second sleeve 753 further clamps the non-circular end of the left end of the intermediate rod 752 inside it, and the pin is inserted into the pin hole 756 of the non-circular end of the right end of the intermediate rod 752 and the first sleeve 721; the above steps realize the assembly and fixation of the rotating shaft 75 to the upper shell 11 of the seat cushion 1; By removing the clamping screw on the second sleeve 753 and pulling out the pin, the intermediate rod 75 can be moved relative to the first sleeve 751 along its axis, thereby pulling out the non-circular end of the right end of the intermediate rod 752. This separates the seat cushion 1 from the support 54, facilitating the maintenance of the disassembled seat cushion 1.

[0033] The middle rod 75 has a through channel along its axial direction, through which external cables and other equipment can be connected to the inside of the seat cushion 1.

[0034] like Figure 15 As shown, the front center of the leather case 6 (relative to the waist position) is provided with several independently controllable air cushions 9. Each air cushion 9 is connected to a corresponding inflation / deflation device (such as an air pump). By inflating and deflating several independent air cushions 9, pneumatic massage of the waist of the human body can be achieved.

[0035] like Figure 16 , Figure 17 As shown, a neck and shoulder massager 2 is installed on the upper part of the backrest 51 via a lifting assembly. The neck and shoulder massager 2 is located on the outside of the leather cover 6. The neck and shoulder massager 2 is used to massage the user's neck and shoulders. This is prior art and is not the focus of this application, so it will not be described in detail here.

[0036] The lifting assembly includes a mechanism 21 and a rack and pinion transmission structure 22 disposed within the backrest 51. The mechanism 21 moves up and down within the backrest 51 via the rack and pinion transmission structure 22. A drive motor is mounted on the mechanism 21 to rotate the gears in the rack and pinion transmission structure 22. The rack and pinion transmission structure 22 and the drive motor constitute the power mechanism for the mechanism 21 to move up and down within the backrest 51. The mechanism 21 is connected to the shoulder and neck massagers 2 on both sides via airbags 25. The inflation and deflation of the airbags 25 control the movement of the shoulder and neck massagers 2 on both sides. The mechanism 21 moves up and down, and the shoulder and neck massagers 2 on both sides extend into the leather case 6 and connect to the airbag 25 through their respective connecting arms 23. The connecting arms 23 on both sides are guided by the guide assembly 231 to move up and down relative to the mechanism 21. A first return spring (not shown in the figure) is also provided between the shoulder and neck massagers 2 and the mechanism 21. The elastic force of the first return spring is used to push the shoulder and neck massagers 2 to move up and return relative to the mechanism 21. The mechanism 21 is also guided up and down within the backrest 51 and the leather case 6 by the guide assembly. The lifting assembly also includes an air pump 24, a pressure detector 26, and an air valve (not shown in the attached diagram). The output end of the air pump 24 is connected to the airbag 25 through a first air pipe, and an air valve is installed on the first air pipe. The air valve can be a three-way valve or similar structure. For example, the first and second ends of the air valve are connected to the air pump 24 and the airbag 25, respectively. The third end of the air valve is open and connected to the outside atmosphere when the power is off, and is closed when the power is on. The three ports of the air valve are interconnected. The airbag 25 is connected to the pressure detector 26 through a second air pipe. The air pressure detector 26 is connected to the airbag 25 through a separate second air tube, avoiding sharing a line with the first air tube delivered by the air pump 24, thereby improving the detection accuracy of the air pressure inside the airbag 25.

[0037] When a user sits on the cushion 1 and controls the neck and shoulder massager 2 to descend and massage the user's neck and shoulders via the control panel 13 or voice interaction with the artificial intelligence interactive device 3, firstly, the air pump 24 pneumatically inflates the airbag 25 to the set air pressure through the first air pipe and air valve. The air valve is energized and isolated from the atmosphere. The airbag 25 inflates and expands its size, causing the neck and shoulder massagers 2 on both sides to overcome the first return spring and descend to a certain height. Afterward, the drive motor drives the mechanism 21 to continue descending a set distance through the gear and rack structure 22 until the neck and shoulder massager 2 contacts the user's neck and shoulders. Because the airbag 25 is flexible and deformable, it reduces the rigid contact between the shoulder and neck massager 2 and the user, thus improving comfort.

[0038] If a sudden power outage occurs, the drive motor will be unable to work and thus cannot drive the mechanism 21 to rise and reset. At this time, after the air valve is de-energized, it will be connected to the atmosphere, and the gas in the airbag 25 will be discharged outward through the first air tube and the air valve. The airbag 25 will deflate and shrink to reset its shape. Then, under the action of the first reset spring, the shoulder and neck massager 2 will rise and reset a short distance relative to the mechanism 21. The shoulder and neck massager 2 rises and resets a short distance to separate from the user's shoulders and neck, making it convenient for the user to remove the device.

[0039] The upper part of the backrest 51 is equipped with an artificial intelligence interaction device 3. The artificial intelligence interaction device 3 is located on the outside of the leather case 6. The front of the artificial intelligence interaction device 3 is equipped with a display screen for display and a built-in speaker for voice interaction. The artificial intelligence interaction device 3 is also equipped with an AI system for intelligent interaction with the user and control of the whole machine.

[0040] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
