Description

Technical Field

[0001] This invention belongs to the field of physiotherapy device technology, and relates to a smart massage chair that helps people get up, especially a smart massage chair specifically designed for the elderly. Background Technology

[0002] Massage chairs use mechanical rolling and squeezing to massage, while manual massage can unblock meridians, promote blood circulation, and maintain the body's yin-yang balance. Therefore, after a massage, you can feel your muscles relax, your joints become more flexible, your spirits are lifted, and your fatigue is eliminated, which plays an important role in maintaining good health.

[0003] However, most existing massage chairs are designed for reclining or lying positions, which is not conducive to the use of the elderly. After using them, the elderly find it difficult to get up independently.

[0004] Traditional massage devices have limited functions and often use simple lifting structures, which can only lift the entire seat. They lack comprehensive consideration for adjusting the user's center of gravity and providing multi-point coordinated assistance. As a result, the user is prone to slipping or insufficient support when getting up, and both safety and comfort need to be improved.

[0005] Insufficient automation and security. Most products rely on manual operation by users to switch modes and reset, lacking intelligent monitoring and automatic reset mechanisms. This increases the operational burden and potential risks, failing to provide a truly safe and convenient user experience for users with limited mobility.

[0006] Therefore, we propose a smart massage chair specifically designed to help the elderly get up. Summary of the Invention

[0007] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a smart massage chair specifically designed for elderly people to help them get up. The technical problem this invention aims to solve is: how to achieve precise linkage between three mechanisms—positioning adjustment, hip support, and side support—to simultaneously complete the forward shift of the center of gravity, hip lift, and underarm support during the getting-up process, forming a safe and effortless power for helping people get up; at the same time, it integrates a professional multi-dimensional massage system covering the back, hips, and legs, providing comprehensive relaxation during rest.

[0008] The objective of this invention can be achieved through the following technical solutions:

[0009] A smart massage chair for elderly people includes an adjustment mechanism and a button controller. The adjustment mechanism has a backrest at the rear, with a back massage mechanism on the backrest. Side armrests are provided on both sides of the adjustment mechanism, with side lifting mechanisms on the inner side of each side armrest. A hip lifting mechanism is provided between the two side armrests. A seat cushion is provided above the adjustment mechanism, and the hip lifting mechanism is connected to the seat cushion. The hip massage mechanism is located inside the seat cushion and is positioned above it. A hinge plate is hinged to the front of the seat cushion, and a mounting plate is hinged below the hinge plate. The mounting plate is connected to the front of the adjustment mechanism, and a leg massage mechanism is provided on the front of the mounting plate. The button controller is electrically connected to the side lifting mechanism, the back massage mechanism, the adjustment mechanism, the hip lifting mechanism, the leg massage mechanism, and the hip massage mechanism.

[0010] Working principle of the invention: Seat state: When the adjustment mechanism is in the initial state, the intelligent massage chair is in seat state.

[0011] Reclining chair state: The adjustment mechanism unfolds, causing the backrest to tilt backward, which in turn causes the mounting plate to tilt upward. The mounting plate then moves the leg massage mechanism synchronously, and the mounting plate causes the hinged plate to unfold. At this time, the Zhuqi Smart Massage Chair is in reclining chair state.

[0012] Assisted Lifting Mode: The adjustment mechanism lifts up, causing all its components to tilt forward, making it easier for the user to stand up. During this process, the side assisting mechanism rises and touches the user's armpits, lifting the user's armpits, while the hip assisting mechanism lifts the user's hips, stably assisting the user to stand up from the intelligent massage chair. At this time, the intelligent massage chair is in the assisting lifting mode.

[0013] The above states can be adjusted using the button controller.

[0014] This smart massage chair automatically resets to the seat position after the user leaves, with the side and hip support mechanisms resetting.

[0015] This smart massage chair can provide massage and health care in both seat and reclining positions, and can massage and relax different parts of the body. The user sits on the buttock support mechanism and leans against the back massage mechanism.

[0016] Back massage: Performed by a back massage mechanism installed on the backrest.

[0017] Buttock massage: Performed by a buttock massage mechanism installed inside the seat box, which can be performed through a buttock lifting mechanism.

[0018] Leg massage: The leg massage mechanism installed on the front of the mounting plate massages the calves and other areas.

[0019] All massage functions and intensity levels can be independently selected and controlled via a button controller.

[0020] The adjustment mechanism includes a base frame, with four-panel plates fixed on both the left and right sides. Four-panel plates four and two, arranged vertically and parallel to each other, are hinged to the front of each of the four-panel plates three. A four-panel plate one is hinged between the front ends of the four-panel plates four and four-panel plates two. A fixing tube is fixed to the upper end of each of the two four-panel plates one, and side fixing plates are fixed to both ends of the fixing tube. Mounting rod one and mounting rod three are hinged to the front of each of the two side fixing plates. Mounting rod four is hinged to the front end of mounting rod three. Mounting rod four is hinged to mounting rod one. Mounting rod two is hinged to the front end of mounting rod one. A mounting base plate is hinged between the front ends of mounting rod four and mounting rod two. The mounting plate is fixed to the front sides of the two mounting base plates. An active rod is hinged to the inner side of each of the two side fixing plates. The middle of the two active rods... An active tube is fixed between the two sides. An adjustment electric push rod is hinged between the middle of the active tube and the upper rear side of the base frame. Side connecting rod 2 is hinged to the rear side of each of the two side plates. A reverse connecting rod is hinged to the rear end of each side connecting rod 2. Side connecting plate 3 is hinged to the front side of the reverse connecting rod. Mounting brackets are fixed to the inner side of each side connecting plate 3. The front end of the mounting bracket is hinged to the upper rear end of mounting plate rod 3 on the same side. A fixing plate is fixed to the lower rear end of each mounting bracket. Side connecting rod 3 is hinged between the lower end of the fixing plate and the lower end of the active rod on the same side. Side connecting rod 1 is hinged to the rear side of the reverse connecting rod. Side connecting plate 2 is hinged between the rear end of side connecting rod 1 and the rear end of side connecting plate 3. Side connecting plate 1 is fixed on side connecting plate 2. The rear end of side connecting plate 1 is hinged to the inner side of the backrest. The seat cushion box is fixed to the upper end of the two mounting brackets.

[0021] Using the above structure, the adjusting electric actuator is the power source for the entire mechanism, and its extension and retraction movement is the starting point for the entire system's operation. One end of the adjusting electric actuator is hinged to the base frame, and the other end is hinged to the active tube. The base frame remains stationary on the ground. When the adjusting electric actuator extends, it pushes the active tube forward and upward. When the adjusting electric actuator retracts, it pulls the active tube backward and downward. The movement of the active tube directly drives the two active rods fixed at its two ends to move synchronously. The linkage between the seat cushion and leg support: The lower end of the active rod is connected to the fixed connecting plate via side linkage three. Therefore, the movement of the active rod is directly transmitted to the mounting frame, which is the mounting base of the seat cushion. Its front part is connected to the mounting base via components such as mounting plate rod three. Final effect: The movement of the active rod, through this four-bar linkage, synchronously drives the tilt angle of the mounting frame and the unfolding and retraction of the mounting base. When the backrest tilts back, the front of the mounting frame lifts, and the mounting base unfolds to support the legs; when the backrest tilts forward, the mounting frame returns to horizontal, and the mounting base retracts. Backrest linkage: The movement of the active lever is simultaneously transmitted to the reverse linkage via side linkage two; the reverse linkage then transmits the movement to side linkage one via side linkage one and side linkage two, ultimately driving the backrest to rotate around its hinge point. This transmission chain design ensures that the movement of the backrest is precisely coordinated with the movement of the mounting bracket and mounting plate. Seat position: The electric adjustment lever is in the middle position, all linkage mechanisms are retracted, the backrest is nearly vertical, the seat cushion is roughly horizontal, and the mounting plate is folded down. Recliner position: The electric adjustment lever retracts, pulling the active tube backward. Through the above transmission path, the backrest tilts backward, while the front of the seat cushion slightly rises, and the mounting plate and the leg massage mechanism above it unfold upward, forming a comfortable reclining posture. Assisted-up state: The electric adjustment rod extends, pushing the active tube forward and upward. The positions of the backrest, seat cushion, and mounting plate remain unchanged, i.e., the seat position is maintained. In this seat position, the whole body tilts forward, shifting the user's center of gravity forward, making it easier to get up. During this process, the side assist mechanism and the hip assist mechanism act synchronously, providing assistance from the armpits and hips.

[0022] The back massage mechanism includes two guide racks and two slide rails, all fixed to the inner side of the backrest. The guide racks and slide rails are arranged parallel to each other, with the guide racks located on the outer side of the slide rails. A back massage body slides on the two slide rails. A moving motor and a back massage motor are fixed inside the back massage body. Two guide gears rotate inside the back massage body, meshing with guide racks on the same side. The output shaft of the moving motor is fixedly connected to the rotating shaft of one of the guide gears. Two back massage wheels rotate on the back massage body, their rotating shafts connected via a pulley pair. The output shaft of the back massage motor is connected to the rotating shaft of one of the back massage wheels.

[0023] Using the above structure, the movement function is as follows: The output shaft of the moving motor directly drives the guide gear to rotate. The guide gear meshes with the guide rack fixed on the backrest. When the gear rotates, it travels along the guide rack, thus driving the entire back massage body to move smoothly up and down along the slide rail; allowing the back massage rollers to cover different areas from the lower back to the upper back. The massage function involves the output shaft of the back massage motor driving the rotating shafts of two back massage rollers through a transmission device. The two back massage rollers rotate synchronously in opposite or the same direction under the drive of the back massage motor, providing a kneading and pushing-style deep massage to the user's back muscles. Fixed-point massage: The moving motor is not working, but the back massage motor is working. The massage rollers rotate and massage in a fixed position. Tracking massage: The moving motor and the back massage motor work simultaneously. While rotating, the massage rollers move slowly up and down, providing a continuous massage along a line or a region of the back.

[0024] The buttock massage mechanism includes a main buttock massage frame, which is fixed inside the seat cushion box. An angle-adjusting arc-shaped gear is hinged to the lower end of the main buttock massage frame. A front-to-back swing motor and a left-to-right swing motor are fixed to the rear side of the angle-adjusting arc-shaped gear. A first transmission swing shaft and a second transmission swing shaft are rotatably mounted on the rear side of the angle-adjusting arc-shaped gear. The output shafts of the front-to-back swing motors are connected to the first transmission swing shaft, and the output shafts of the left-to-right swing motors are connected to the second transmission swing shaft. Both ends of the first transmission swing shaft have rotatably mounted transmission swing blocks. Both ends of the second transmission swing shaft are eccentric shafts, and both ends have rotatably mounted swing frames. A ball-head connecting rod is hinged between the lower end of the swing frame and the transmission swing block on the same side. Two buttock massage wheels distributed in a Y-shape are rotatably mounted on the upper end of each swing frame. An angle-adjusting motor is fixed to the lower end of the main buttock massage frame, and an angle-adjusting gear is fixed to the output shaft of the angle-adjusting motor, meshing with the angle-adjusting arc-shaped gear.

[0025] Using the above structure, the kneading is carried out in the front and back directions, and the power transmission is as follows: front and back swing motor → transmission swing shaft one → transmission swing blocks at both ends.

[0026] Action execution: When the transmission swing shaft rotates, it drives the transmission swing block to make circular motion. The transmission swing block pushes or pulls the lower end of the swing frame through the ball joint connecting rod, so that the entire swing frame swings back and forth with its upper end as the fulcrum.

[0027] Final effect: The two hip massage rollers installed on the upper part of the swing frame roll back and forth, creating a deep pressing and kneading sensation similar to that of a thumb.

[0028] Kneading in the left and right directions, power transmission: left and right swing motor → transmission swing shaft two → swing frame.

[0029] Action execution: When the transmission swing shaft rotates, the eccentric shafts at both ends will directly drive the lower part of the swing frame, causing it to swing left and right.

[0030] Final effect: Similarly, this will cause the two hip massage rollers to swing from side to side, simulating horizontal kneading and pushing techniques.

[0031] Composite massage mode: When the two motors work together, the two movements mentioned above are superimposed, and the hip massage roller can walk out a complex figure-eight or elliptical trajectory to achieve multi-dimensional three-dimensional kneading massage, greatly improving comfort and professional feel.

[0032] Overall adjustment of massage angle: The output shaft of the angle adjustment motor drives the angle adjustment gear to rotate, and the angle adjustment gear drives the angle adjustment arc gear component, so that the angle adjustment arc gear component rotates around the hinge point of the buttock massage main frame.

[0033] Final result: The angle of the entire actuator assembly, which includes two oscillating motors and massage rollers, is changed. This ensures that the massage rollers conform to the user's hip curve at the optimal angle in different sitting postures, providing a precise and effective massage.

[0034] The inner side of each side armrest is provided with an L-shaped side mounting chamber 1 and a rectangular side mounting chamber 2. The side mounting chamber 2 is located in front of the side mounting chamber 1. The upper part of the side mounting chamber 1 is trumpet-shaped. The inner side of each side armrest is provided with a laser sensor.

[0035] With the above structure, when the laser sensor detects that a user is seated: the system remains on standby, allowing functions such as massage and posture adjustment to be performed. Its most crucial function is when the system detects that the user has left. The system triggers an automatic reset procedure, restoring the extended side support mechanism, the raised hip support mechanism, and the tilting adjustment mechanism to their initial "seat state" for future use. Side mounting chamber one provides storage and operating space for the side support mechanism. Side mounting chamber two is used to install some components of the side support mechanism.

[0036] The side-mounting mechanism includes a lifting seat rod and an L-shaped lifting base. The lifting base is detachably installed inside the side mounting chamber. The lifting seat rod is hinged to the front of the lifting base. An angle-adjusting electric push rod is hinged between the lower end of the lifting seat rod and the lifting base. A lifting electric push rod is fixed inside the lifting seat rod. A lifting support is fixed to the upper end of the lifting electric push rod. Two side guide rods are fixed to the lower end of the lifting support. The side guide rods are slidably installed inside the lifting seat rod. When the lifting support is stored, it is stored inside the side mounting chamber. A pressure sensor is provided above the lifting support.

[0037] Using the above structure, the angle-adjusting electric push rod extends and retracts, its pushing force acting on the lower end of the lifting seat rod. This force pushes the entire lifting seat rod around its hinge point, causing the upper end of the lifting seat rod to swing back and forth. Simultaneously with the angle-adjusting electric push rod's movement, the lifting electric push rod extends, its pusher end directly lifting the lifting support seat. Guided by the side guide rod, the lifting support seat rises vertically and smoothly, extending from the vertical portion of the L-shaped chamber, ultimately contacting and supporting the user's armpit area. The pressure sensor detects the user's weight pressure, ensuring the pressure value remains within a certain threshold, thus stably lifting the user forward from the device. Reset and retraction: When the user leaves and the pressure sensor detects no pressure, the angle-adjusting and lifting electric push rods retract synchronously in reverse order. The lifting electric push rod retracts first, lowering the lifting support seat and retracting it into the lifting seat rod. The angle-adjusting electric push rod then retracts, pulling the lifting seat rod to rotate in the opposite direction, returning the lifting seat rod to its initial vertical position.

[0038] The hip-lifting mechanism includes two symmetrically arranged mounting frames. The mounting frames are detachably installed inside the side mounting chamber two on the same side. Each mounting frame has a rotatable lifting screw inside. The lower end of the mounting frame is fixed with a lifting motor, which is located inside the side mounting chamber two. The output shaft of the lifting motor is fixedly connected to the lifting screw on the same side. The lifting screw is driven by a hinged slide, which is slidably installed inside the mounting frame on the same side. A U-shaped frame is hinged between the two hinged slides. The upper end of the U-shaped frame is provided with an elastic support cloth. The front side of the upper end face of the elastic support cloth and the left and right sides are provided with reinforcing strips. The front end of the elastic support cloth is connected to the front side of the seat cushion box.

[0039] With the above structure, the side strips enhance the tensile strength of the elastic support cloth. Two lifting motors start synchronously, and the output shafts of the motors directly drive the lifting screw to rotate. The hinged slides, which mesh with the lifting screw, convert the rotational motion of the lifting screw into a precise linear upward motion. The two hinged slides rise synchronously within the two mounting frames. The two synchronously rising hinged slides together push the U-shaped frame upward. The upper end of the U-shaped frame is connected to the elastic support cloth. As the U-shaped frame rises, the elastic support cloth, which was originally laid flat on the seat box, is lifted upward, directly contacting and supporting the user's buttocks, providing the main lift. The front end of the elastic support cloth is connected to the front side of the seat box, so that the elastic support cloth forms an inclined slope, ensuring that the user can stably leave the device. After the user gets up and leaves, the lifting motor reverses, driving the lifting screw to rotate in the opposite direction, causing the hinged slides, U-shaped frame, and elastic support cloth to descend completely below the plane of the seat box, restoring the flat surface of the seat box.

[0040] The leg massage mechanism includes a leg massage housing, which is detachably mounted on the front side of the mounting plate. The leg massage housing has two symmetrically arranged leg placement holes, each with a vibrating massage plate on its upper side. Inside the leg massage housing are four rotating massage elements, arranged in groups of two, with each group's two elements facing each other and extending above and below the leg placement holes. A massage spindle rotates inside the leg massage housing, and a leg massage motor is fixed inside. The output shaft of the leg massage motor is connected to the massage spindle. Two sets of circumferentially distributed rotating massage wheels are fixed on the massage spindle, each group containing four wheels and facing the center of the leg placement holes. Four inclined side-clamping massage plates rotate on the massage spindle, with the two middle side-clamping massage plates symmetrically arranged and the two outer side-clamping massage plates symmetrically arranged. The two side-clamping massage plates on the same side face the leg placement holes.

[0041] Using the above structure, the rotating kneading massage works as follows: The leg massage motor drives the massage spindle to rotate, which in turn drives the rotating massage wheels to directly act on the muscles of the middle posterior side of the calf, such as the Chengshan acupoint, providing deep rolling and kneading massage to effectively relieve muscle soreness. Four side-clamping massage plates are rotatably mounted on the massage spindle at an angle. As the spindle rotates, their tilted installation angle creates a periodic opening and closing motion; the two pairs of side-clamping massage plates rhythmically clamp and relax the inner and outer sides of the calf, simulating the "grasping" motion of a human hand to relax the lateral calf muscles. The vibrating massage plate is located above the leg opening, close to the front of the calf. Its effect: it generates high-frequency vibration, effectively stimulating the muscles and meridians of the front of the calf, promoting blood circulation, and relieving numbness in the legs and feet. The symmetrically arranged rotating massage pieces clamp the area near the Achilles tendon and the lower end of the calf from both above and below, providing deep, targeted rotating kneading in this key area prone to leg fatigue.

[0042] Compared with existing technologies, this smart massage chair for seniors has the following advantages:

[0043] This solution utilizes three mechanisms working in tandem: positioning, hip support, and side support, to create a complete lifting process. The positioning mechanism first shifts the user's center of gravity forward, the hip support mechanism provides the main lift, and the side support mechanism offers underarm support and balance assistance. The three mechanisms work together to ensure a smooth, effortless, and safe lifting process.

[0044] The massage system is professionally and comprehensively designed, covering three major areas: the back, buttocks, and legs. The back massager features movable kneading, the buttocks provide multi-dimensional massage, and the legs have kneading, pinching, and vibration functions, effectively relaxing the main muscle groups throughout the body and enhancing overall comfort.

[0045] The intelligent control and safety system is highly integrated, allowing for centralized management of all functions via a button controller, making operation simple. A laser sensor enables automatic reset upon leaving the seat, and a pressure sensor ensures appropriate lifting force, significantly improving the product's automation level and safety performance.

[0046] The overall structural design is ingenious and space-efficient. The complex multi-link adjustment mechanism requires only one electric push rod to achieve multiple posture switching; all functional modules are hidden inside the massage chair body, resulting in a neat appearance when stored. This highly integrated design achieves numerous functions within a limited space, balancing aesthetics and practicality. Attached Figure Description

A side connecting plate 15 is fixed on the side connecting plate 16. The rear ends of the side connecting plate 15 are all hinged to the inner side of the backrest 3. The seat cushion box is fixed to the upper end of the two mounting brackets 20.

[0071] The adjusting electric actuator 33 is the power source for the entire mechanism, and its extension and retraction movement is the starting point for the entire system's operation. One end of the adjusting electric actuator 33 is hinged to the base frame 27, and the other end is hinged to the active tube 32. The base frame 27 remains stationary on the ground. When the adjusting electric actuator 33 extends, it pushes the active tube 32 to move forward and upward. When the adjusting electric actuator 33 retracts, it pulls the active tube 32 to move backward and downward. The movement of the active tube 32 directly drives the two active rods 69 fixed at its two ends to move synchronously. Linkage between the seat box and the leg support: The lower end of the active rod 69 is connected to the fixed connecting plate 19 (belonging to the mounting frame 20) through the side connecting rod 36. Therefore, the movement of the active rod 69 is directly transmitted to the mounting frame 20, which is the mounting base of the seat box. Its front part is connected to the mounting base plate 23 through components such as the mounting plate rod 25. Final effect: The movement of the active lever 69, through this four-bar linkage, synchronously drives the tilt angle of the mounting bracket 20 and the unfolding and retraction of the mounting base plate 23. When the backrest tilts back, the front of the mounting bracket 20 lifts up, and the mounting base plate 23 unfolds to support the legs; when the backrest tilts forward, the mounting bracket 20 returns to horizontal, and the mounting base plate 23 retracts. Backrest linkage: The movement of the active lever 69 is simultaneously transmitted to the reverse linkage 70 through the second side linkage 34; the reverse linkage 70 then transmits the movement to the first side linkage 15 through the first side linkage 18 and the second side linkage plate 16, ultimately driving the backrest 3 to rotate around its hinge point. This transmission chain design ensures that the movement of the backrest 3 is precisely coordinated with the movement of the mounting bracket 20 and the mounting base plate 23. Seat state: The adjustment electric push lever 33 is in the middle state, all linkage mechanisms are retracted, the backrest 3 is nearly vertical, the seat cushion is roughly horizontal, and the mounting plate 10 is drooping and retracted. Reclining chair state: The adjusting electric push rod 33 retracts, pulling the active tube 32 backward. Through the aforementioned transmission path, the backrest 3 tilts backward, while the front of the seat cushion box slightly rises. The mounting plate 10 and the leg massage mechanism 9 above it unfold upward, forming a comfortable reclining posture. Assisted standing state: The adjusting electric push rod 33 extends, pushing the active tube 32 forward and upward. The positions of the backrest 3, seat cushion box, and mounting plate 10 remain unchanged, i.e., the chair state is maintained. In this chair state, the entire structure tilts forward, shifting the user's center of gravity forward, making it easier to stand up. During this process, the side assist mechanism 2 and the hip assist mechanism 6 operate synchronously, providing assistance from the armpits and hips.

[0072] The back massage mechanism 4 includes two guide racks 11 and two slide rails 12. The two guide racks 11 and two slide rails 12 are fixed on the inner side of the backrest 3. The two guide racks 11 and two slide rails 12 are arranged in parallel, and the two guide racks 11 are located on the outer side of the two slide rails 12. The back massage body 13 is slidably mounted on the two slide rails 12. A moving motor and a back massage motor are fixed inside the back massage body 13. Two guide gears are rotatably mounted inside the back massage body 13. The guide gears mesh with the guide racks 11 on the same side respectively. The output shaft of the moving motor is fixedly connected to the rotating shaft of one of the guide gears. Two back massage wheels 14 are rotatably mounted on the back massage body 13. The rotating shafts of the back massage wheels 14 are connected to each other through a belt pulley pair. The output shaft of the back massage motor is connected to the rotating shaft of one of the back massage wheels 14.

[0073] Movement function: The output shaft of the moving motor directly drives the guide gear to rotate. The guide gear meshes with the guide rack 11 fixed on the backrest. When the gear rotates, it will move along the guide rack 11, thereby driving the entire back massage body 13 to move smoothly up and down along the slide rail 12; so that the back massage roller 14 can cover different areas from the lower back to the upper back.

[0074] Massage function: The output shaft of the back massage motor drives the rotating shaft of the two back massage rollers 14 through the transmission device; the two back massage rollers 14 rotate synchronously in opposite or the same direction under the drive of the back massage motor, and perform kneading and pushing deep massage on the user's back muscles.

[0075] Fixed-point massage: The moving motor is not working, but the back massage motor is working. The massage rollers rotate and massage in a fixed position.

[0076] Linear massage: The moving motor and the back massage motor work simultaneously. While the massage rollers rotate, the entire unit moves slowly up and down, providing a continuous massage along a line or a region of the back.

[0077] The buttock massage mechanism includes a main buttock massage frame 45, which is fixed inside the seat cushion box. An adjustable arc-shaped gear 43 is hinged to the lower end of the main buttock massage frame 45. A front-to-back swing motor 41 and a left-to-right swing motor 42 are fixed to the rear side of the adjustable arc-shaped gear 43. A first transmission swing shaft and a second transmission swing shaft are rotatably mounted on the rear side of the adjustable arc-shaped gear 43. The output shaft of the front-to-back swing motor 41 is connected to the first transmission swing shaft, and the output shaft of the left-to-right swing motor 42 is connected to the second transmission swing shaft. Both ends of the first transmission swing shaft are equipped with transmission swing blocks 39, and both ends of the second transmission swing shaft are eccentric shafts. Both ends of the second transmission swing shaft are equipped with swing frames 38. The lower end of the swing frame 38 is hinged to the transmission swing block 39 on the same side with a ball joint connecting rod 40. The upper end of the swing frame 38 is equipped with two buttock massage rollers 37 distributed in a Y shape. The lower end of the buttock massage main frame 45 is fixed with an angle adjustment motor 44. An angle adjustment gear is fixed on the output shaft of the angle adjustment motor 44. The angle adjustment gear meshes with the angle adjustment arc gear piece 43.

[0078] Kneading in the front and back direction, power transmission: front and back swing motor 41 → transmission swing shaft 1 → transmission swing blocks 39 at both ends.

[0079] Action execution: When the transmission swing shaft rotates, it drives the transmission swing block 39 to make a circular motion. The transmission swing block 39 pushes or pulls the lower end of the swing frame 38 through the ball joint 40, so that the entire swing frame 38 swings back and forth with its upper end as the fulcrum.

[0080] Final effect: The two hip massage rollers 37 installed on the upper part of the swing frame 38 roll back and forth, creating a deep pressing and kneading sensation similar to that of a thumb.

[0081] Kneading in the left and right directions, power transmission: left and right swing motor 42 → transmission swing shaft 2 → swing frame 38.

[0082] Action execution: When the transmission swing shaft 2 rotates, the eccentric shafts at both ends will directly drive the lower part of the swing frame 38, causing it to swing left and right.

[0083] Final effect: Similarly, this will cause the two hip massage rollers 37 to swing left and right, simulating horizontal kneading and pushing techniques.

[0084] Composite massage mode: When the two motors work together, the two movements mentioned above are superimposed, and the hip massage roller 37 can walk out a complex figure-eight or elliptical trajectory to achieve multi-dimensional three-dimensional kneading massage, greatly improving comfort and professional feel.

[0085] Overall adjustment of massage angle: The output shaft of the angle adjustment motor 44 drives the angle adjustment gear to rotate, and the angle adjustment gear drives the angle adjustment arc gear component 43, so that the angle adjustment arc gear component 43 rotates around the hinge point of the buttock massage main frame 45.

[0086] Final result: The angle of the entire actuator assembly, which includes two oscillating motors and massage rollers (i.e., the angle-adjusting arc gear 43 and all its components), changes. This ensures that the massage rollers can conform to the user's hip curve at the optimal angle in different sitting postures (such as seated or reclining positions), providing precise and effective massage.

[0087] The inner side of the side handrail 1 is provided with an L-shaped side mounting chamber 49 and a rectangular side mounting chamber 54. The side mounting chamber 54 is located in front of the side mounting chamber 49. The upper part of the side mounting chamber 49 is trumpet-shaped. The inner side of the side handrail 1 is provided with a laser sensor 50.

[0088] When the laser sensor 50 detects that the user is seated: the system remains on standby, allowing functions such as massage and posture adjustment to be performed.

[0089] When the system detects that the user has left (i.e., the signal has disappeared): This is its most crucial function. The system will trigger an automatic reset procedure, restoring the extended side support mechanism, the raised hip support mechanism, and the tilt adjustment mechanism to their initial "seat state" for the next use.

[0090] The side mounting chamber 49 (L-shaped) is the storage and operating space for the side lifting mechanism 2.

[0091] The side mounting chamber 2 54 (rectangular) is used to install some components of the side lifting mechanism 2.

[0092] The side-mounting mechanism 2 includes a lifting seat rod 46 and an L-shaped lifting base 48. The lifting base 48 is detachably disposed inside the side mounting chamber 49. The lifting seat rod 46 is hinged to the front side of the lifting base 48. An angle-adjusting electric push rod 47 is hinged between the lower end of the lifting seat rod 46 and the lifting base 48. A lifting electric push rod 52 is fixed inside the lifting seat rod 46. A lifting support 53 is fixed to the upper end of the lifting electric push rod 52. Two side guide rods 51 are fixed to the lower end of the lifting support 53. The side guide rods 51 are slidably disposed inside the lifting seat rod 46. When the lifting support 53 is stored, it is stored inside the side mounting chamber 49. A pressure sensor is provided above the lifting support 53.

[0093] The angle-adjusting electric push rod 47 extends and retracts, its pushing force acting on the lower end of the lifting seat rod 46. This force pushes the entire lifting seat rod 46 around its hinge point, causing the upper end of the lifting seat rod 46 to swing back and forth. Simultaneously with the angle-adjusting electric push rod 47's movement, the lifting electric push rod 52 begins to extend. The push rod end of the lifting electric push rod 52 directly lifts the lifting support seat 53. The lifting support seat 53, guided by the side guide rod 51, rises vertically and smoothly upwards, extending from the vertical portion of the L-shaped chamber, ultimately contacting and supporting the user's armpit area. The pressure sensor detects the user's body pressure. Heavy pressure ensures that the pressure sensor value remains at a certain threshold, steadily lifting the user forward from the device; Reset and storage: When the user leaves (detected by laser sensor 50), and the pressure sensor detects no pressure, the angle-adjusting electric push rod 47 and the lifting electric push rod 52 retract synchronously in reverse order; the lifting electric push rod 52 retracts first, lowering the lifting support 53 and retracting it into the lifting support rod 46; the angle-adjusting electric push rod 47 then retracts, pulling the lifting support rod 46 to rotate in the opposite direction, so that the lifting support rod 46 is in its initial vertical state.

[0094] The hip-lifting mechanism 6 includes two symmetrically arranged mounting frames 57. The mounting frames 57 are detachably mounted inside the side mounting chamber 2 54 on the same side. Each mounting frame 57 has a rotatable lifting screw 55 inside. The lower end of the mounting frame 57 is fixed with a lifting motor 58, which is located inside the side mounting chamber 2 54. The output shaft of the lifting motor 58 is fixedly connected to the lifting screw 55 on the same side. The lifting screw 55 is driven by a hinged slide 56, which is slidably mounted inside the mounting frame 57 on the same side. A U-shaped frame 59 is hinged between the two hinged slides 56. The upper end of the U-shaped frame 59 is provided with an elastic support cloth 61. The front side of the upper end face of the elastic support cloth 61 and the left and right sides are provided with reinforcing strips 60. The front end of the elastic support cloth 61 is connected to the front side of the seat cushion box.

[0095] The reinforcing strip 60 enhances the tensile force of the elastic support cloth 61. Two lifting motors 58 start synchronously, and their output shafts directly drive the lifting screw 55 to rotate. The hinged slide 56, meshing with the lifting screw 55, converts the rotational motion of the lifting screw 55 into precise linear upward motion. The two hinged slides 56 rise synchronously within the two mounting frames 57. The two synchronously rising hinged slides 56 jointly push the U-shaped frame 59 upward. The upper end of the U-shaped frame 59 is connected to the elastic support cloth 61. As the U-shaped frame 59 rises... The elastic support cloth 61, which was originally laid flat on the seat box, is lifted upwards, directly contacting and supporting the user's buttocks, providing the main lift. The front end of the elastic support cloth 61 is connected to the front side of the seat box, so that the elastic support cloth 61 forms an inclined slope to ensure that the user can leave the device stably. After the user gets up and leaves, the lifting motor 58 reverses, drives the lifting screw 55 to rotate in the opposite direction, and drives the hinged slide 56, U-shaped frame 59 and elastic support cloth 61 to descend and completely retract below the plane of the seat box, restoring the flat surface of the seat box.

[0096] The leg massage mechanism 9 includes a leg massage housing 62, which is detachably mounted on the front side of the mounting plate 10. The leg massage housing 62 has two symmetrically arranged leg placement holes 63, each with a vibrating massage plate 67 on its upper side. The leg massage housing 62 contains four rotating massage elements 64, arranged in groups of two. Each group of two rotating massage elements faces each other and extends above and below the leg placement holes 63. A massage spindle 68 is rotatably mounted inside the leg massage housing 62. The leg massager housing 62 houses a leg massage motor. The output shaft of the leg massage motor is connected to the massage spindle 68. Two sets of circumferentially distributed rotating massage wheels 66 are fixed on the massage spindle 68. Each set of rotating massage wheels 66 consists of four wheels and is positioned directly opposite the center of the leg passage hole 63. Four inclined side clamp massage plates 65 are rotatably mounted on the massage spindle 68. The two middle side clamp massage plates 65 are symmetrically arranged, and the two outer side clamp massage plates 65 are symmetrically arranged. The two side clamp massage plates 65 on the same side are directly opposite the leg passage hole 63.

[0097] Rotary kneading massage (driven by a leg massage motor): The leg massage motor operates, driving the massage spindle 68 to rotate, which in turn drives the rotating massage rollers 66 to rotate. This directly acts on the muscles of the middle posterior side of the calf, such as the Chengshan acupoint, providing deep rolling and kneading massage to effectively relieve muscle soreness. Four side-clamping massage plates 65 are rotatably mounted on the massage spindle at an angle. As the massage spindle 68 rotates, their tilted installation angle creates a periodic opening and closing motion. The two pairs of side-clamping massage plates 65 rhythmically clamp and relax the inner and outer sides of the calf, simulating the "grabbing" motion of a human hand to relax the lateral muscles of the calf. The vibrating massage plate 67 is located above the leg opening, close to the front of the calf. Its effect: It generates high-frequency vibration, effectively stimulating the muscles and meridians on the front of the calf, promoting blood circulation, and relieving numbness in the legs and feet. The symmetrically arranged rotating massage pieces 64 clamp the area near the Achilles tendon and the lower part of the calf from both above and below, performing deep, targeted rotating kneading. This area is a key point where the legs are prone to fatigue.

[0098] Working principle of the invention:

[0099] Core Foundation: Adjustment Mechanism 5 – the "skeleton" of posture switching. The entire massage chair's shape changes are achieved through a precise multi-link adjustment mechanism. The power source is the adjustment electric push rod 33.

[0100] Work mode:

[0101] Seat position: The electric adjustment lever 33 is at its middle length. The backrest 3 is upright, the seat cushion is horizontal, and the mounting plate 10 is folded down, making it suitable for use as a massage chair.

[0102] Recliner position: The electric adjustment lever 33 retracts, and through the linkage system, the backrest 3 tilts backward. At the same time, the front of the seat cushion box is slightly raised, and the mounting plate 10 unfolds upward to form a comfortable reclining posture.

[0103] Assisted standing state: The electric push rod 33 extends, pushing the entire upper structure (backrest, seat cushion, legboard) forward as a whole, shifting the user's center of gravity forward and creating the best mechanical conditions for standing up.

[0104] As the positioning mechanism 5 enters the "assistive lifting state," two specialized assistive lifting mechanisms are simultaneously activated to provide direct assistance.

[0105] Side lifting mechanism 2 (underarm support): The angle-adjusting electric push rod 47 extends and retracts, and its pushing force acts on the lower end of the lifting seat rod 46. The pushing force will push the entire lifting seat rod 46 with its hinge point as the axis, causing the upper end of the lifting seat rod 46 to swing back and forth.

[0106] As the angle-adjusting electric push rod 47 moves, the lifting electric push rod 52 begins to extend. The push rod end of the lifting electric push rod 52 directly lifts the support seat 53. The support seat 53 rises vertically and smoothly along the guide of the side guide rod 51, extending from the vertical part of the L-shaped chamber, and finally touching and supporting the user's armpit area.

[0107] The pressure sensor detects the user's weight pressure and ensures that the pressure value of the pressure sensor is always at a certain threshold, so as to steadily lift the user forward from the device and help him away.

[0108] Reset and storage: When the user leaves (via laser sensor 50) and the pressure sensor detects no pressure, the angle adjustment electric push rod 47 and the lifting electric push rod 52 retract in opposite order; the lifting electric push rod 52 retracts first, lowering the lifting seat 53 and retracting it into the lifting seat rod 46.

[0109] The electric push rod 47 retracts again, pulling the lifting rod 46 to rotate in the opposite direction, so that the lifting rod 46 is in the initial vertical state.

[0110] Hip-lifting mechanism 6: Two lifting motors 58 start synchronously. The output shaft of the lifting motor 58 directly drives the lifting screw 55 to rotate. The hinged slide 56 that meshes with the lifting screw 55 converts the rotational motion of the lifting screw 55 into a precise linear upward motion. The two hinged slides 56 rise synchronously within the two mounting frames 57.

[0111] Two synchronously rising articulated slides 56 jointly push the U-shaped frame 59 upward. The upper end of the U-shaped frame 59 is connected to the elastic support cloth 61. As the U-shaped frame 59 rises, the elastic support cloth 61, which was originally laid flat on the seat box, is lifted upward, directly contacting and lifting the user's buttocks, providing the main lift.

[0112] The front end of the elastic support 61 is connected to the front side of the seat box, so that the elastic support 61 forms an inclined slope to ensure that the user can leave the device stably.

[0113] When the user gets up and leaves, the lifting motor 58 reverses, driving the lifting screw 55 to rotate in the opposite direction, causing the hinged slide 56, U-shaped frame 59 and elastic support cloth 61 to descend completely below the seat box plane, restoring the flat seat box surface.

[0114] Summary of the assisted standing process: Positioning mechanism 5 leans forward (shifts the center of gravity forward) → Hip assisted standing mechanism 6 lifts up (main lifting force) → Side assisted standing mechanism 2 supports (underarm support and balance). The three mechanisms work together to assist the user in standing up in the most effortless and safest way.

[0115] The massage function can be activated when the chair or recliner is in position.

[0116] Back massage mechanism 4: The moving motor drives the guide gear to move along the guide rack 11, which in turn moves the back massage body 13 up and down along the slide rail 12 to cover the entire back; the back massage motor drives the two back massage rollers 14 to rotate and perform kneading massage; it can perform fixed-point massage or up and down tracking massage.

[0117] Hip massage mechanism: The front and back swing motor 41 and the left and right swing motor 42 respectively drive a set of crank connecting rod mechanism, so that the upper hip massage wheel produces two kinds of movements: front and back pitch and left and right swing; the two movements are superimposed, and the massage wheel can walk out a complex figure-eight trajectory to achieve three-dimensional kneading.

[0118] The angle-adjusting motor 44 can adjust the angle of the entire massage module to ensure a close fit to the curves of the buttocks in different postures.

[0119] Leg massage mechanism 9: The leg massage motor drives the massage spindle 68, and the rotating massage rollers on the massage spindle 68 roll and knead the calves.

[0120] The inclined side clamp massage plate on the massage spindle 68 rotates with the spindle to produce a periodic opening and closing motion, pinching the sides of the calf.

[0121] An independent vibrating massage plate 67 stimulates the front of the calf. Symmetrically arranged rotating massage pieces 64 specifically knead the Achilles tendon area.

[0122] Intelligent control and safety system: Button controller 7 is the central control terminal, which can switch the seat position, start / stop the start function, and select the massage mode and intensity.

[0123] Laser sensor 50: Installed under the armrest, it detects whether the user is seated. When the system detects that the user has left, it automatically triggers a reset procedure, restoring all the assistive mechanisms and adjustment mechanisms to their initial "seat state," which is both energy-efficient and safe.

[0124] Pressure sensor: Integrated into the side support seat to ensure effective and safe support during lifts.

[0125] In summary, this solution utilizes three mechanisms working in tandem—positioning, hip support, and side support—to create a complete lifting process. The positioning mechanism shifts the user's center of gravity forward, the hip support mechanism provides the main lift, and the side support mechanism offers underarm support and balance assistance. The three mechanisms work together to ensure a smooth, effortless, and safe lifting process.

[0126] The massage system is professionally and comprehensively designed, covering three major areas: the back, buttocks, and legs. The back massager features movable kneading, the buttocks provide multi-dimensional massage, and the legs have kneading, pinching, and vibration functions, effectively relaxing the main muscle groups throughout the body and enhancing overall comfort.

[0127] The intelligent control and safety system is highly integrated, allowing for centralized management of all functions via a button controller, making operation simple. A laser sensor enables automatic reset upon leaving the seat, and a pressure sensor ensures appropriate lifting force, significantly improving the product's automation level and safety performance.

[0128] The overall structural design is ingenious and space-efficient. The complex multi-link adjustment mechanism requires only one electric push rod to achieve multiple posture switching; all functional modules are hidden inside the massage chair body, resulting in a neat appearance when stored. This highly integrated design achieves numerous functions within a limited space, balancing aesthetics and practicality.

[0129] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
