Description

[Technical Field]

[0001] The present invention relates to an auxiliary standing health leisure stool that rotates magnetic poles by a motor. [Background technology]

[0002] A massage sofa is one of the health and physical therapy devices commonly used in people's daily lives. By installing massage devices on the massage sofa, it is possible to massage many parts of the body, such as the back and buttocks, of the person sitting on the massage sofa, thereby relaxing the human body and relieving fatigue.

[0003] Currently, diseases such as hypertension, diabetes, and cardiovascular disease have become common among the Chinese population, and the age at which they are affected is gradually becoming younger. Medical research has shown that the occurrence of microcirculatory disorders is the root cause of many diseases, and traditional Chinese medicine practitioners believe that the best treatment method is to utilize the body's self-regulating mechanism. How to promote the body's microcirculation and strengthen the body's self-regulating mechanism is an inevitable trend in future social development. As a form of health care, magnetic therapy is considered a relatively safe method of human physical therapy, but existing massage sofas do not have magnetic therapy functions. Summary of the Invention [Problem to be solved by the invention]

[0004] SUMMARY OF THE INVENTION The present invention aims to provide an auxiliary standing health leisure stool that uses a motor to rotate magnetic poles, in order to solve the problems in the background art. [Means for solving the problem]

[0005] The above technical object of the present invention is achieved by the following technical solutions: a sofa bracket that is fitted and connected to the sofa body; the sofa body includes a cushion, a seat back, and a footrest; the seat back is installed behind the cushion, and the footrest is installed in front of the cushion; the seat back includes a lumbar support and a headrest from bottom to top; a rotary magnetic motor is installed inside both the lumbar support and the cushion; the rotary magnetic motor has a strength of 8500-10000GS and effectively exhibits high strength and high penetration to provide optimal performance; and a magnetic strip is installed inside the footrest and the headrest.

[0006] The present invention adds a rotary magnetic motor through the cushion and seat back, which can cover most areas of the human body. Furthermore, by adding the distribution of six magnetic stripes, the surface magnetic field of the magnetic stripes is more than 2500 gauss, which makes the distribution region and area of ​​the magnetic field wider. Through the distribution of dynamic and static magnetism, users can better enjoy the effect of the magnetic field, which gives the health leisure stool a magnetic therapeutic effect and plays a health role.

[0007] Preferably, the sofa bracket includes a lifting device and an electric push rod for driving the lifting device, the electric push rod including a drive motor, a lead screw, a slider, a housing, a guide rod, an internally hollow push rod, a first stroke switch, a second stroke switch, and a third stroke switch, the drive motor is installed in the housing, the lead screw is fixed to the output end of the drive motor, the guide rod is installed above the lead screw and is parallel to the lead screw, the slider is fitted into the side walls of the lead screw and the guide rod, the slider is threaded onto the lead screw and slidably connected to the guide rod, the push rod is fitted onto the outside of the lead screw and fixedly connected to the slider, and the first stroke switch, the second stroke switch, and the third stroke switch are arranged in an array on the top of the housing.

[0008] In this invention, the rotation of the rotary motor rotates the lead screw, causing the slider to slide along the lead screw, thereby extending and retracting the push rod. When the slider contacts the first stroke switch, the lifting device is activated and the sofa is placed in a lying position, with a lying position angle of approximately 170 degrees, allowing the user to sleep easily. When the slider contacts the second stroke switch, the lifting device is activated and the sofa is placed in a sitting position. When the slider contacts the third stroke switch, the lifting device is activated and the sofa is placed in an assisted standing position. The assisted standing function can assist the user in standing up, freeing the user's knees from the weight of the entire body, making it easier to stand up, which is particularly useful for the elderly and those with knee problems.

[0009] The lifting device is a prior art and is described in detail in, for example, Patent CN108125435A, Elderly Chair Mechanical Device CN112021847A, Elderly Chair Lifting Drive Mechanism, Seat Frame and Seat Patents, so it will not be described here; however, by controlling the electric push rod, the sofa body can be in a sitting position, a lying position and an assisted standing position.

[0010] Preferably, the rotary magnetic motor includes a motor mounting housing that is open at both ends, a brushless motor, a rotating shaft, a magnet, and a magnet mounting shell, one end of the magnet mounting shell is closed and the other end is open, the two magnet mounting shells are installed at both ends of the motor mounting housing with the open ends of the magnet mounting shells facing the motor mounting housing, the rotating shaft is installed within the motor mounting housing and both ends extend into the magnet mounting shell, the brushless motor is installed within the motor mounting housing, and the two magnets are installed at both ends of the rotating shaft and fixedly connected to the outer wall of the rotating shaft.

[0011] In the present invention, the brushless motor rotates the magnet, which realizes the exchange position of N and S class magnetic fields and realizes dynamic magnetism.

[0012] By installing magnets on both ends of the brushless motor and installing a housing on the outside, the entire rotary magnetic motor is placed into the cushion and seat back, allowing the magnets to be firmly fixed to the seat back and seat of the massage chair, and as the angle of the chair body changes constantly during operation, it can follow the changes in the angle of the chair body.

[0013] Preferably, the entire structure is connected with a soft connection method of the fabric cover, so that the abnormal noise transmitted from the irregular vibration caused by the rotation of the motor is not audible to the human ear, and noise pollution is avoided.

[0014] The product adopts a stepless adjustment method to adjust different angles of the back and legs, allowing the user to always be in the most comfortable and desired position, so that the whole body and mind are in the best condition.

[0015] The product is designed with superfiber leather, which is comfortable to sit on, has a bright luster, is highly absorbent and breathable, and is also wear-resistant. It is refreshing in the summer and does not feel sticky, and does not feel cold in the winter.

[0016] The rotary magnetic motor is installed under the chair cushion and attached to the back to support the shoulders, neck and back. The fixing method is robust and the operation is stable. The voltage of the chair is 24V, and the control system is integrated into the control panel of the chair, making the operation simple and clear. The control system is constantly optimized and improved, and can be integrated into the control system of the massage chair itself to realize the interlocking method.

[0017] The rotating shaft has support bearings located on both sides of the brushless motor, the support bearings are installed on the rotating shaft, the inner ring of the support bearing is fixedly connected to the rotating shaft, and the outer ring of the support bearing is fixedly connected to the side wall of the motor mounting housing, and the distance between the two support bearings is 60 to 65 mm.

[0018] The present invention increases the distance between the two support bearings, thereby lengthening the length of the brushless motor, thereby increasing the torque of the brushless motor without changing the overall dimensions of the rotary motor. This prevents the magnets at both ends from being attracted by an external force, causing the rotary magnetic motor to malfunction, and prevents the motor from being pulled and damaging the bearings, thereby improving the life of the rotary motor.

[0019] Preferably, a fixing ring is molded on each end of the motor mounting housing, the outer diameter of the fixing ring being smaller than the outer diameter of the port of the motor mounting housing, the fixing ring having a plurality of tapered grooves formed along the circumferential direction, balls installed in the tapered grooves, a first retaining ring installed on the outside of the tapered grooves, a compression spring fitted into the fixing ring, one end of the compression spring abutting the port of the motor mounting housing and the other end abutting the first retaining ring, a second retaining ring fixedly connected to the outer wall of the first retaining ring, an insert ring molded on the open end of the magnet mounting shell, the outer wall of the insert ring having a ball locking groove for facilitating the dropping of the balls, and a tapered tip of the insert ring, an elastic seal ring molded on the surface of the port of the fixing ring, and a seal locking groove formed in the magnet mounting shell for interlocking with the elastic seal ring.

[0020] In this invention, by sliding the second retaining ring, the compression spring is pushed out, causing the first retaining ring to displace and move away from the ball, allowing it to move. The insert ring is then inserted into the fixed ring, first pushing the ball away from the inner wall of the fixed ring. The ball is blocked by the second retaining ring and does not fall out of the tapered through groove. The ball then engages in the ball locking groove of the insert ring. After that, the insert ring is released, and the second retaining ring and the first retaining ring are subjected to the elastic force of the compression spring, causing displacement. The first retaining ring blocks the outer wall of the tapered through groove, and the elastic seal ring is engaged in the seal locking groove. This quickly completes the installation between the motor mounting housing and the magnet mounting shell, providing a sturdy installation that is easy to assemble, disassemble, and maintain later on. This also enhances the waterproof performance of the rotary magnetic motor and enhances the safety of the health and leisure seat.

[0021] Preferably, the diameter of the tapered through groove increases gradually in a direction from the inner wall of the fixing ring toward the outer wall thereof to prevent the balls from falling off the inner wall of the fixing ring.

[0022] Preferably, the fixing ring has a limit stopper ring fixedly connected to it at a position close to the tapered through groove, and the first retaining ring can be blocked by the limit stopper ring.

[0023] Preferably, a magnetic isolation sheet is provided on one side of the magnet close to the brushless motor, and the magnetic isolation sheet is fixedly connected to a side wall of the rotating shaft. The provision of the magnetic isolation sheet prevents the magnetic force of the magnetic material from affecting the operation of the rotor and stator structures, reduces the escape of magnetic force along the motor axis, and allows the magnetic field to concentrate perpendicular to the motor axis.

[0024] Preferably, the cushion and lumbar support are further provided with massage areas, which may be rollers or airbags, and can massage various parts of the human body.

[0025] Two sets of massage airbags are distributed throughout the seat and back, filling and releasing air at different frequencies to generate a massage effect.

[0026] The head and legs have a total of six flexible magnetic stripes evenly distributed, generating a constant static magnetic field that is stable and effective.

[0027] The chair is controlled by a hand controller and has a tilt function and a standing function, and the tilt angle is about 170 degrees, allowing the human body to sleep comfortably.

[0028] Preferably, the present invention has a one-touch reset function, a function of pressing the on key to shut down and reset to the off state at any state, and a function of automatically resetting after turning the power on again. [Effects of the Invention]

[0029] In summary, the beneficial effects of the present invention are as follows:

[0030] 1. The present invention adds a rotating magnetic motor through the cushion and seat back, which can cover most areas of the human body. Furthermore, by adding six magnetic stripes, the distribution area and surface area of ​​the magnetic field is wider. Through the distribution of dynamic and static magnetism, users can better enjoy the effect of the magnetic field, which gives the health leisure seat a magnetic therapy effect and plays a health role.

[0031] 2. In this invention, the rotation of the rotary motor rotates the lead screw, causing the slider to slide along the lead screw, thereby extending and retracting the push rod. When the slider contacts the first stroke switch, the lifting device is activated, causing the sofa to enter a lying position at a lying position angle of approximately 170 degrees, making it easy for the user to sleep. When the slider contacts the second stroke switch, the lifting device is activated, causing the sofa to enter a sitting position. When the slider contacts the third stroke switch, the lifting device is activated, causing the sofa to enter an assisted standing position. The assisted standing function can assist the user in getting up, freeing the user's knees from the weight of the entire body, making it easier to stand up, which is particularly useful for the elderly and those with knee problems.

[0032] 3. In this invention, sliding the second retaining ring pushes out the compression spring, displacing the first retaining ring and releasing it from the ball, allowing it to move. The insert ring is then inserted into the fixed ring, pushing the ball away from the inner wall of the fixed ring. The ball is blocked by the second retaining ring and does not fall out of the tapered groove. The ball then engages in the ball locking groove of the insert ring. After that, the insert ring is released, and the second and first retaining rings are subjected to the elastic force of the compression spring, causing displacement. The first retaining ring blocks the outer wall of the tapered groove, and the elastic seal ring is engaged in the seal locking groove. This quickly completes the installation between the motor mounting housing and the magnet mounting shell, providing a sturdy installation that is easy to assemble, disassemble, and maintain later. This also enhances the waterproof performance of the rotary magnetic motor and enhances the safety of the health and leisure seat. [Brief explanation of the drawings]
