Description

Technical Field

[0001] This invention relates to the field of intelligent massage chair technology, specifically to an intelligent massage chair. Background Technology

[0002] Massage chairs use mechanical pressure to massage the body, unblocking meridians, enhancing blood circulation, and physically stimulating muscle tissue to help relax tense muscle groups. They are especially suitable for people who sit, stand, or maintain a fixed posture for long periods of time, eliminating fatigue and playing an important role in health. Massage can also promote blood circulation, improve back pain and prevent diseases, improve sleep quality, relieve overall fatigue, improve posture, and promote a healthy body.

[0003] However, the massage positions of existing massage chairs are relatively fixed. Users of different heights, weights, and body types have significant differences in bone structure and muscle distribution, making it inconvenient to adjust the position according to the body type of adults and children. At the same time, the massage intensity and stimulation methods of massage chairs may cause harm to the body of thinner people. In addition, since children's bones are not fully developed, excessive massage intensity may cause spinal damage.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing smart massage chairs. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention comprises a lead screw, a moving block, a telescopic rod, a fixed block, a connecting plate, an adjusting block, and a contact plate. An infrared sensor on the top surface of the massage frame detects the user's height, controlling a drive motor to rotate the lead screw. The rotation of the lead screw causes the moving block to move laterally, which in turn causes the adjusting block to move along a limiting groove on the inner side of the massage frame until it reaches the appropriate massage position. This achieves precise alignment with the user's back muscles, avoiding the discomfort caused by misalignment in mechanical massage. Simultaneously, the contact plate, as the adjusting block moves, abuts against the lateral movement of the massage heads, adjusting the spacing between the massage heads. This adapts to the shoulder and waist widths of people of different heights, allowing the massage heads to better fit the user's muscle groups, significantly improving comfort, accuracy, ease of operation, and user experience.

[0018] 2. This invention comprises a first oil tank, a first piston rod, a first contact block, a second oil tank, a second piston rod, a compression block, a third piston rod, a second contact block, a third oil tank, and a sealing plate. When a patient sits on the massage chair, the compression block is pressed downwards against the second piston rod, thereby squeezing the oil in the second oil tank into the first oil tank, which in turn compresses the first piston rod upwards. The upward movement of the first piston rod contacts the first contact block, causing it to move to both sides and contact the contact plate. This changes the upward movement distance of the contact plate, thus allowing the massage chair to automatically reduce the intensity for lighter users to prevent excessive force from causing harm, while increasing the intensity for heavier users to ensure the massage effect.

[0019] 3. In this invention, the movement of the moving block drives the movement of the second contact block, which in turn moves the third piston rod upward, squeezing the oil in the second oil tank into the third oil tank. This reduces the amount of oil in the second oil tank, thereby changing the range of massage head intensity adjustment. The intensity of the massage head can be dynamically adjusted according to actual needs, providing a more flexible user experience and preventing spinal damage caused by excessive massage chair intensity adjustment due to the weight of children or shorter users.

[0030] 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.

[0031] Please see Figures 1-9 This invention provides a technical solution: an intelligent massage chair, including a device base 1, a massage frame 2 fixedly connected to the top of the device base 1, side plates 3 fixedly connected to the top of the device base 1 on both sides of the massage frame 2, a covering cushion 4 covering the surface of the massage frame 2 and the side plates 3, an infrared sensor installed on the top surface of the massage frame 2, when the user sits on the covering cushion 4, the infrared sensor on the top surface of the massage frame 2 detects the user's height, which facilitates the adjustment of the massage position, a projection screen 5 installed on one side of the device base 1, an adjustment block 6 slidingly limited in a groove opened inside the massage frame 2, a movable disc 7 slidingly limited in the top cavity inside the adjustment block 6, a position adjustment mechanism installed at the bottom inside the device base 1, and a rotating massage mechanism installed inside the adjustment block 6;

[0032] The position adjustment mechanism includes a lead screw 81 rotatably connected to the inner wall of the bottom end of the device base 1. The lead screw 81 is driven by a drive motor in the left side cavity of the bottom end of the device base 1. A moving block 82 is sleeved on the surface of the lead screw 81. A telescopic rod 83 is fixedly connected to the top of the moving block 82. A fixed block 84 is rotatably connected to the top of the telescopic rod 83. A connecting plate 85 is fixedly connected to the top of the fixed block 84. The top of the connecting plate 85 is fixedly connected to the bottom of the adjustment block 6. An abutment plate 86 is installed inside the massage frame 2 and is adjusted from the bottom. The bottom chamber of segment 6 passes through the middle position. Six sets of movable discs 7 are symmetrically arranged in the top chamber of adjustment block 6. The bottom of the six sets of movable discs 7 are fixedly connected to limit blocks 13. The bottom end of the limit block 13 near the contact plate 86 is fixedly connected to a contact rod 14. The end of the contact rod 14 abuts against the contact surface of the contact plate 86. The opposite side of the limit block 13 is connected by a fifth spring. The contact plate 86 is set as an arc structure corresponding to the massage frame 2. The contact surfaces on both sides of the contact plate 86 are set as inclined structures.

[0033] The drive motor inside the device base 1 drives the lead screw 81 to rotate. The rotation of the lead screw 81 causes the moving block 82 to move laterally. The lateral movement of the moving block 82 causes the telescopic rod 83 to move laterally. The lateral movement of the telescopic rod 83 causes the fixed block 84 to move. The fixed block 84 moves the connecting plate 85 laterally. The lateral movement of the connecting plate 85 causes the adjusting block 6 to move along the limiting slide groove on the inner side of the massage frame 2 until it moves to the appropriate massage position for the user, accurately corresponding to the position of the lower back muscles, avoiding misalignment and discomfort of mechanical massage.

[0034] In one embodiment of the present invention, the rotating massage mechanism includes a main gear 91 located at the center of the movable disk 7. Four driven gears 92 are evenly distributed around the main gear 91. This design of four driven gears 92 around the main gear 91 ensures the uniformity and continuity of the massage force. The tooth surfaces of the driven gears 92 mesh with the tooth surfaces of the main gear 91. A rotating frame 93 is provided at the bottom of the driven gears 92, and the bottom of the driven gears 92 is rotatably connected to the rotating frame 93. A drive motor is installed inside the limiting block 13, and the output end of the drive motor extends to the movable disk. Inside the drive gear 92, a sleeve 94 is fixedly connected to the top of the drive motor output end and the bottom of the main gear 91. A massage contact 95 is fixedly connected to the top of the driven gear 92. A first spring is fixedly connected to the bottom of the massage contact 95. The other end of the first spring is fixedly connected to the bottom of the sleeve 94. A contact plate 96 is sleeved around the sleeve 94. The contact plate 96 is fixedly connected to both sides of the bottom of the massage contact 95 through a connecting rod. A receiving block 97 is fixedly connected to the top of the main gear 91. A force adjustment component is installed inside the receiving block 97.

[0035] The drive motor inside the start limit block 13 drives the rotating frame 93 to rotate. The rotation of the rotating frame 93 drives the driven gear 92 to rotate around the main gear 91. At the same time, since the main gear 91 and the driven gear 92 mesh with each other, the driven gear 92 rotates on its own while rotating around the main gear 91. At this time, the first abutting block 983 will abut against the abutting disk 96 and move up and down and rotate in the limit sliding groove outside the sleeve 94, driving the massage contact head 95 to perform a moderate massage on the user and improve the comfort of the massage.

[0036] In one embodiment of the present invention, the force adjustment component includes a first oil tank 981 installed at the bottom of the interior of the accommodating block 97. A first piston rod 982 is slidably limited within the first oil tank 981. A first abutting block 983 is disposed in the top cavity of the accommodating block 97. The top of the first piston rod 982 is configured as a frustum and abuts against the back end of the first abutting block 983. The first abutting block 983 is slidably limited within through grooves on both sides of the top of the accommodating block 97. The end of the first abutting block 983 furthest away from the top is configured as a slope and abuts against the periphery of the abutting plate 96. The first abutting block 983 is located at the top of the accommodating block 97. One end of the chamber is connected by a second spring. A second oil tank 984 is fixedly connected to the top of the right chamber inside the device base 1. A second piston rod 985 is slidably limited in the oil chamber above the second oil tank 984. A squeezing block 986 is fixedly connected to the top of the second piston rod 985. The top of the squeezing block 986 is located between the massage frames 2. A locking block 15 is installed on the inner wall of the right end of the device base 1 by an electric push rod. A locking groove is opened on the right side of the squeezing block 986 corresponding to the locking block 15. A third spring is fixedly connected to both sides of the bottom of the squeezing block 986. The other end of the third spring is fixed to the top of the right chamber inside the device base 1. The connection is such that a third piston rod 987 is slidably limited within the oil chamber below the second oil tank 984. The oil chamber below the first oil tank 981 is connected to the left oil hole of the middle oil chamber of the second oil tank 984 via a hose with a liquid check valve. The oil chamber below the third oil tank 11 is connected to the right oil hole of the middle oil chamber of the second oil tank 984 via a hose with a liquid check valve. When the moving block 82 stops moving, the left oil hole in the middle of the second oil tank 984 opens and the right oil hole closes. At this time, the electric push rod on the inner wall of the right end of the controller base 1 in the massage chair retracts, driving the locking block. 15. Disengage from the slot on the right side of the squeezing block 986 to unlock the squeezing block 986. At this time, the user's buttocks will press the squeezing block 986 downward. The downward movement of the squeezing block 986 will drive the second piston rod 985 downward. The downward movement of the second piston rod 985 will squeeze the oil in the second oil tank 984 into the first oil tank 981 through the hose, thereby squeezing the first piston rod 982 upward. The upward movement of the first piston rod 982 will abut against the first abutting block 983 and move it to both sides. The first abutting block 983 will move to both sides and abut against the abutting plate 96 and move it upward, thereby changing the distance that the abutting plate 96 moves upward.

[0037] In one embodiment of the present invention, a second abutment block 10 is fixedly connected to the right side of the bottom of the movable block 82. The abutment surface of the second abutment block 10 is set as an inclined structure and corresponds to the bottom position of the third piston rod 987. A third oil tank 11 is fixedly connected to the inner wall of the right side cavity of the device base 1. A sealing plate 12 is slidably limited inside the third oil tank 11. A fourth spring is fixedly connected to the top of the sealing plate 12. The other end of the fourth spring is fixedly connected to the top of the inside of the third oil tank 11. When the second abutment block 10 moves laterally to abut against the third piston rod 987 and moves upward, the left oil hole of the oil chamber in the middle of the second oil tank 984 is sealed by a one-way valve and the left oil hole is opened. The third piston rod 987 moves upward and squeezes the oil inside the second oil tank 984 into the third oil tank 11 through the left oil hole, reducing the amount of oil in the second oil tank 984. This changes the range of intensity adjustment of the massage head 95, preventing children and users with shorter stature from having their massage chair intensity adjusted too high due to their weight, which could lead to spinal damage.

[0038] Working principle: When using this smart massage chair, the user first sits on the cushion 4. At this time, the infrared sensor on the top surface of the massage frame 2 detects the user's height, which in turn controls the drive motor inside the base 1 to drive the lead screw 81 to rotate. The rotation of the lead screw 81 causes the moving block 82 to move laterally. The lateral movement of the moving block 82 causes the telescopic rod 83 to move laterally. The lateral movement of the telescopic rod 83 causes the fixed block 84 to move. The lateral movement of the fixed block 84 causes the connecting plate 85 to move laterally. The lateral movement of the connecting plate 85 causes the adjusting block 6 to move along the limiting groove on the inner side of the massage frame 2. The adjustment block 6 moves along the limiting groove on the inner side of the massage frame 2 until it moves to the appropriate massage position for the user, accurately corresponding to the position of the back muscles, avoiding the discomfort caused by mechanical massage. While the adjustment block 6 moves along the limiting groove on the inner side of the massage frame 2, the contact surface of the contact plate 86 will contact the contact rod 14 and move to both sides. The contact rod 14 moves to both sides and pushes the limiting block 13 to move to both sides. The limiting block 13 moves to both sides and drives the moving plate 7 to move to both sides. The moving plate 7 moves to both sides and drives the massage head 95 to move to both sides, thereby adjusting the spacing of the massage head 95 to adapt to the shoulder width and waist width of people of different heights.

[0039] As the moving block 82 moves, it drives the second abutment block 10 to move laterally. The second abutment block 10 moves laterally and abuts the third piston rod 987 to move upward. At this time, the left oil hole of the oil chamber in the middle of the second oil tank 984 is sealed by a one-way valve and the left oil hole is opened. The third piston rod 987 moves upward and squeezes the oil inside the second oil tank 984 into the third oil tank 11 through the left oil hole, reducing the amount of oil in the second oil tank 984. This changes the range of intensity adjustment of the massage head 95, preventing children and shorter users from having their massage chair intensity adjusted too high due to their weight, which could lead to spinal damage.

[0040] When the moving block 82 stops moving, the oil hole on the left side of the middle of the second oil tank 984 opens and the oil hole on the right side closes. At this time, the electric push rod on the inner wall of the right end of the controller control device base 1 in the massage chair retracts, causing the locking block 15 to disengage from the slot on the right side of the squeezing block 986, thus unlocking the squeezing block 986. At this time, the user's buttocks will press the squeezing block 986 downward, causing it to move downward. The downward movement of the squeezing block 986 drives the second piston rod 985 downward. The downward movement of the second piston rod 985 squeezes the oil in the second oil tank 984 into the first oil tank 981 through the hose, thereby squeezing the first piston rod 982 upward. The upward movement of the first piston rod 982 then contacts... The first contact block 983 moves to both sides, and the first contact block 983 moves to both sides to abut against the contact plate 96 and move upward, thereby changing the distance that the contact plate 96 moves upward. Then, the drive motor inside the limit block 13 is activated to drive the rotating frame 93 to rotate. The rotation of the rotating frame 93 drives the driven gear 92 to rotate around the main gear 91. At the same time, since the main gear 91 and the driven gear 92 mesh with each other, the driven gear 92 rotates on its own while rotating around the main gear 91. At this time, the first contact block 983 will abut against the contact plate 96 and move up and down and rotate within the limit groove on the outside of the sleeve 94, driving the massage head 95 to give the user a moderate massage and improve the comfort of the massage.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
