Description

Technical Field

[0001] The invention belongs to the field of seats, and in particular relates to a massage chair and a massage movement thereof. Background Art

[0002] General office chairs can only meet the daily sitting needs and do not have massage functions. Therefore, office chairs with massage functions have appeared, including a massage chair frame and a massage movement. The massage chair frame is provided with a guide rail. The massage movement includes a mounting frame. The mounting frame can slide up and down along the guide rail. The mounting frame is provided with massage rollers for massaging the human body, a kneading component for driving the massage rollers for kneading, and a knocking component for driving the massage rollers for knocking. A walking component for driving the mounting frame to move along the guide rail is provided between the mounting frame and the guide rail. The walking component includes an active walking shaft, a walking roller, a walking gear and a walking motor. The active walking shaft is rotatably arranged on the mounting frame. The walking motor is fixedly arranged on the mounting frame and drives the active walking shaft to rotate. The walking roller is arranged at the end position of the active walking shaft and can roll along the guide rail. The walking gear is arranged beside the walking roller. The guide rail is provided with a rack meshing with the walking gear. The walking motor drives the walking gear to rotate, thereby driving the mounting frame to slide up and down along the guide rail.

[0003] However, the above-mentioned massage movement can only perform kneading massage and percussion massage with a single strength; therefore, patent documents such as publication numbers CN2922880Y, CN100382775C, CN202505713U, CN208448086U, CN109620672A, CN109846683A, CN100581523C, CN109248042A, CN109259995A, CN208448086U, TW201410230A, CN110353963A, CN110314078A, CN109172253A, CN209392344U, and CN209392345U all use a tiltable base on the mounting frame to adjust the massage strength.

[0004] However, since the base is tilted as a whole, the tilt angle of the base is often small due to space and other factors, which leads to the following two problems:

[0005] 1) The massage intensity adjustment range of the massage movement is small and cannot meet the needs of a wide range of users;

[0006] 2) When massage is not needed, the massage roller protrudes from the back of the massage chair, that is, when the user leans on the back of the massage chair, the massage roller will press against the back of the human body, seriously affecting the comfort of the user.

[0007] Therefore, a Chinese patent document with publication number CN109620673A discloses an angle-adjustable massage manipulator, comprising a mounting frame and a massage head assembly, wherein the massage head assembly comprises a curved arm and a massage head, wherein the massage head is arranged on the curved arm, and the mounting frame is also provided with a kneading assembly for driving the curved arm and the massage head to move, wherein the kneading assembly comprises a kneading shaft rotatably arranged on the mounting frame, wherein the curved arm is rotatably arranged on the kneading shaft, wherein the mounting frame is provided with an adjusting mechanism capable of adjusting the rotation angle of the curved arm, wherein the adjusting mechanism comprises a rotating seat, wherein the rotating seat is rotatably arranged on the mounting frame, wherein the rotating seat can drive the curved arm to rotate to realize angle adjustment of the curved arm, and wherein the mounting frame is provided with a driving assembly capable of driving the rotating seat to rotate; by adopting the above scheme, the massage manipulator can adjust the angle of the massage head, is convenient for storage, and has better comfort.

[0008] However, technicians in this field have found that this solution also has the following problems during use:

[0009] 1) In the adjustment mechanism, the rotation of the rotating part and the adjustment of the angle of the crank arm are realized by the sliding of the slider and the cooperation of the rack and gear on the slider. The gear on the rotating seat is not a complete gear, so the gear may slip during the rotation of the rotating seat. At the same time, due to the limited sliding space of the slider, it is difficult to adjust the angle of the massage crank arm to more than 90 degrees. This is because when the adjustment angle of the massage crank arm exceeds 90 degrees, the space required for the slider to slide is relatively long, which in turn extends the length of the entire massage movement, which will affect the overall stroke of the massage movement, that is, the range of movement of the massage movement on the massage chair is reduced, and the area that can be massaged on the back of the human body is also reduced accordingly;

[0010] 2) In the adjustment mechanism, it is difficult to change the corresponding transmission ratio, whether it is the coordination between the rack on the slider and the gear on the rotating seat, or the coordination between the slider and the screw thread, and the motor speed is very fast, that is, the adjustment process of the massage arm is also very fast, which makes it difficult to accurately adjust the massage arm;

[0011] 3) The rotating seat in the adjustment mechanism has the function of cooperating with the rack and the crank arm, so the rotating seat needs to go through a relatively complicated processing process to be produced, that is, the processing difficulty of the rotating seat is large and the processing cost is high; in addition, it is very difficult to process the helical gear for the rotating seat with a special structure, which means that the possibility of directly cooperating with the rotating seat through the worm is very low; at the same time, although it is feasible to process the spur gear for the rotating seat with a special structure, it is difficult to process it precisely, which means that the transmission efficiency of the rotating seat is not high;

[0012] 4) The slider in the adjustment mechanism has the function of sliding with the slide groove and cooperating with the screw thread, so that the slider needs to go through a relatively complicated processing process to be produced, that is, the processing difficulty of the slider is large and the processing cost is high; Summary of the invention

[0013] The object of the present invention is to provide a massage chair and a massage movement thereof, wherein the massage movement can adjust the massage arm to an angle of up to 180 degrees by arranging an adjustment mechanism on the kneading shaft to facilitate storage and improve comfort.

[0044] Embodiment 1:

[0045] like Figure 1-7 A massage movement shown in the figure comprises a movement frame 1 and two massage arms 10 arranged on the left and right of the movement frame 1 and a kneading component, wherein the kneading component comprises a kneading shaft 20 and a first motor 21 mounted on the movement frame 1, wherein the massage arm 10 is sleeved on the kneading shaft 20 and can rotate, and a massage roller 11 is mounted on the top of the massage arm 10, and the first motor 21 drives the kneading shaft 20 to rotate and makes the massage rollers 11 on the two massage arms 10 approach each other or move away from each other to achieve a kneading action, wherein the massage roller 11 can be directly and rotatably mounted on the massage arm 10 through a rotating shaft, and reference can also be made to the installation method of the massage roller 11 in the publication number CN109620672A; the massage roller 11 can be a non-magnetic roller or a magnetic roller.

[0046] In this embodiment, it also includes a first gear 30 and two rotating seats 31 which are sleeved on the kneading shaft 20 and rotate synchronously. The two rotating seats 31 are respectively installed on the left and right sides of the first gear 30. The rotating seat 31 includes left and right side walls and a connecting wall 319 connecting the left and right side walls. A groove for accommodating the tail of the massage crank arm 10 is formed between the left and right side walls. A limiting groove 312 is provided on the connecting wall 319. The tail end of the massage crank arm 10 extends to form a limiting column 100. The limiting column 100 is inserted into the limiting groove 312 and can move in the limiting groove 312. The second motor 33 installed on the movement frame 1 drives the first gear 30 and the rotating seat 31. The massage arm 10 is rotated, thereby driving the massage arm 10 to rotate around the kneading axis 20, so that the angle of the massage arm 10 can be adjusted, and the following two technical effects are achieved. First, when the user does not need the massage arm 10 for massage, the massage arm 10 can be adjusted to a degree that it does not protrude from the backrest surface to achieve a storage effect; second, different massage intensities can be adjusted by adjusting the angle of the massage arm 10.

[0047] In this embodiment, an adjustable reduction box 34 is installed on the movement frame 1, and a worm 32 and a first gear 30 are installed in the adjustable reduction box 34. The worm 32 is meshed with the first gear 30 for transmission, and the second motor 33 is connected to the worm 32 for transmission. The kneading shaft 20 passes through the adjustable reduction box 34, and the two rotating seats 31 are respectively located on the left and right sides of the adjustable reduction box 34. The left and right side surfaces of the first gear 30 are exposed from the adjustable reduction box 34 and are respectively fixedly connected to the left and right rotating seats 31. In this way, the installation of the worm 32 and the axial fixation of the first gear 30 are completed through the housing of the adjustable reduction box 34, so that the structural layout is more reasonable and the volume space is more compact;

[0048] In addition, both the first gear 30 and the worm 32 can be made of universal parts, which do not require special processing and are low in cost, which is conducive to mass production in industrial production; at the same time, the transmission ratio between the two is adjustable, so that a reduction transmission can be formed between the first motor 21 and the massage arm 10, which is conducive to improving the adjustment accuracy of the massage arm 10, and there is little gear slippage in the transmission between the first gear 30 and the worm 32; it is conducive to improving the stability of the operation of the massage arm 10, and reducing the number of transmission stages between the second motor 33 and the rotating seat 31, thereby improving the transmission efficiency.

[0049] In this embodiment, the first gear 30 and the rotating seat 31 are matched with each other through at least two first mounting holes 300 and at least two first protrusions 310 to achieve synchronous rotation of the first gear 30 and the rotating seat 31;

[0050] Alternatively, the first gear 30 and the rotating seat 31 can be rotated synchronously by cooperation between a non-circular second mounting hole 311 and the second protrusion 301; thus, the installation between the rotating seat 31 and the first gear 30 is very convenient and simple.

[0051] like Figure 5 The rotating seat 31 shown is the first implementation in this embodiment: the entire rotating seat 31 is directly injection molded, and a first rounded rectangular through hole is provided on the connecting wall 319 of the rotating seat 31, and the first through hole is the limiting groove 312. Such a setting is simple to process and low in cost.

[0052] like Figure 6 The rotating seat 31 shown is the second implementation mode in this embodiment: a second through hole is provided on the connecting wall 319 of the rotating seat 31, and a connecting member 313 is also fixedly installed on the connecting wall 319 of the rotating seat 31, and a third through hole in the shape of a rounded rectangle is provided on the connecting member 313, and the third through hole is the limiting groove 312, wherein the side wall of the third through hole passes through the second through hole and abuts against the second through hole. The rotating seat 31 is divided into two separate parts in this way, so as to meet the strength required by the fixing frame and the smoothness required by the limiting groove 312 respectively through different materials, and also for the convenience of processing, such as the fixing frame can be formed by bending a plate, or can be formed by direct injection molding, and the limiting groove 312 can be directly injection molded, which is simple to process and low in cost.

[0053] It is worth noting that in the above two embodiments of the rotating seat 31, the distance between the two open ends of the first through hole and the third through hole is significantly greater than the thickness of other parts of the rotating seat 31. This arrangement is because the massage arm 10 needs to withstand a large force during the massage process, and the part where the bottom end of the massage arm 10 contacts the limiting groove 312 is the main force point. Therefore, by increasing the contact area between the bottom end of the massage arm 10 and the limiting groove 312, the possibility of breakage of the tail end of the massage arm 10 can be reduced.

[0054] In this embodiment, the distance between the axis of the kneading shaft 20 and the connecting wall 319 may be greater than the radius of the first gear 30; this arrangement is to reduce the lever difference between the two ends of the massage crank arm 10. Generally speaking, the distance between the massage end of the massage crank arm 10 and the kneading shaft 20 is much greater than the distance between the rear end of the massage crank arm 10 and the kneading shaft 20. In this way, when performing massage, the force of the back of the human body on the massage end of the massage crank arm 10 is converted into the force of the rear end of the massage crank arm 10 on the side wall of the limiting groove 312. Therefore, increasing the distance between the axis of the kneading shaft 20 and the connecting wall 319 can also reduce the possibility of the rear end of the massage crank arm 10 breaking.

[0055] In this embodiment, the circumferential portion of the limiting column 100 that contacts the inner wall of the limiting groove 312 is an arc surface; further preferably, the limiting column 100 is cylindrical and completely passes through the limiting groove 312; such a setting prevents the limiting column 100 from detaching from the limiting groove 312 during movement.

[0056] In this embodiment, a detection component is further provided, and the detection component includes a trigger component and a detection component for detecting the trigger component, wherein the trigger component is mounted on the rotating seat 31 and the detection component is mounted on the movement frame 1 .

[0057] In this embodiment, the first motor 21 is connected to the kneading shaft 20 through the kneading reduction box 22, one end of the kneading shaft 20 extends into the kneading reduction box 22, and the other end of the kneading shaft 20 is mounted on the first mounting seat 13 through a bearing. The kneading reduction box 22 and the first mounting seat 13 are respectively fixed on the movement frame 1.

[0058] In this embodiment, the kneading shaft 20 includes a left section, a middle section and a right section, the first gear 30 is installed on the middle section of the kneading shaft 20, two eccentric sleeves are respectively installed on the left section and the right section of the kneading shaft 20, and the two massage crank arms 10 are respectively installed on the outer rings of the two eccentric sleeves, and the left and right side walls of the rotating seat 31 are hollowly sleeved on the kneading shaft 20 and are respectively located on the left and right sides of the massage crank arm 10; wherein, the inner ring of the eccentric sleeve is fixedly connected to the kneading shaft 20, and the axis line of the inner ring shaft hole of the eccentric sleeve is arranged to be inclined and intersected with the axis line of the outer ring shaft hole of the eccentric sleeve; further preferably, the eccentric sleeve includes a fixedly connected left eccentric sleeve 23 and a right eccentric sleeve 24 to facilitate the installation of the massage crank arm 10, the left end of the left eccentric sleeve 23 abuts against the left side wall of the rotating seat 31 and the right section of the right eccentric sleeve 24 abuts against the right side wall of the rotating seat 31, thereby limiting the axial movement of the rotating seat 31.

[0059] It is worth noting that, in other embodiments, the axis lines of the left and right sections of the kneading shaft 20 may be arranged to intersect with the axis line of the middle section of the kneading shaft 20 in an inclined manner, and the kneading effect can also be achieved.

[0060] In this embodiment, active running wheels are installed on the left and right sides of the movement frame 1, and the active running wheels are driven by the third motor 51. The wheel axis of the active running wheel is perpendicular to the motor axis of the third motor 51, the axis of the kneading shaft 20 is parallel to the wheel axis of the active running wheel and perpendicular to the axis of the worm 32, the motor axis of the second motor 33 is perpendicular to the axis of the worm 32, and the motor axis of the first motor 21 is perpendicular to the axis of the kneading shaft 20. In this way, the structural layout is more reasonable and the volume space is more compact.
