DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0021] Embodiment: Reference Figures 1-8 A modular neck and waist physiotherapy chair shown in the figure, including chair cushion 1, back cushion 2, chair cushion 1, back cushion 2 are respectively provided with first support plate 3, second support plate 4, first support plate 3 and second support plate 4 are fixedly connected, chair cushion 1 and back cushion 2 are both made of elastic material (such as sponge), two armrests 5 are fixedly installed on the top of first support plate 3, hand massage roller 6 is movably arranged between two armrests 5, a plurality of arc protrusions are uniformly arranged on the outer wall of hand massage roller 6, installation groove is formed in one side of chair cushion 1 and first support plate 3, leg support plate 14 is rotatably installed in the installation groove, linkage mechanism is connected between hand massage roller 6 and leg support plate 14, upper cavity and lower cavity are formed in second support plate 4, a plurality of round plates 30 are movably arranged in lower cavity through interval adjusting mechanism, rotating mechanism for driving a plurality of round plates 30 to rotate is arranged in lower cavity, recesses are formed in the outer wall of a plurality of round plates 30, massage plates 32 are slidably installed in the recesses, and the massage plates 32 and the round plates 30 are connected through telescopic mechanism, neck massage mechanism is arranged in upper cavity, and the neck massage mechanism is connected with the rotating mechanism, and the relative inner walls of the upper cavity and the lower cavity are provided with avoiding holes, specifically, two avoiding holes are respectively corresponding to the positions of a plurality of round plates 30 and the neck massage mechanism.

[0022] By the above structure, the chair cushion 1 bears the weight of the user's hips, and the back cushion 2 provides support by fitting the back, and the two are fixedly connected by the first support plate 3 and the second support plate 4 inside, ensuring that the overall structure does not deviate when under stress. The user's hands rest on the armrest 5, and the hand massage roller 6 can directly contact the hands, and the hand massage roller 6 rotates to achieve hand massage, and the legs rest on the leg support plate 14, which is reciprocally rotated to drive the legs to bend, achieving the effect of physiotherapy. When physiotherapy is performed on the waist, the horizontal position of the plurality of circular plates 30 can be adjusted by the telescopic mechanism, and the plurality of circular plates 30 and the plurality of massage plates 32 can be synchronously rotated by the rotating mechanism to perform physiotherapy on the waist, while the neck massage mechanism simultaneously performs physiotherapy on the neck.

[0023] As shown in Figure 2 and Figure 3 , one of the armrests 5 has a turnover slot at the top, and a turnover block 7 is rotatably installed in the turnover slot. The first mounting shaft 8 is rotatably installed on the side of the turnover block 7, and the hand massage roller 6 is fixedly sleeved on the outer wall of the first mounting shaft 8. The other armrest 5 has a rectangular cavity, and the side inner wall of the rectangular cavity has a first rotating hole. A rotating shaft 9 is rotatably installed in the first rotating hole, and the first mounting shaft 8 and the rotating shaft 9 are connected by a clamping mechanism.

[0024] By the above structure, the turnover slot at the top of one of the armrests 5 cooperates with the turnover block 7 to achieve adjustable angle of the hand massage roller 6. When the user needs to sit down or stand up, the turnover block 7 can be turned up to lift the hand massage roller 6, avoiding hindering the movement of the body. After sitting down, the turnover block 7 is reset to make the hand massage roller 6 fall back to the appropriate massage height, ensuring that the arc-shaped protrusion can accurately contact the palm when the hand is naturally placed.

[0025] As shown in Figure 2 , Figure 3 and Figure 4 , the clamping mechanism includes a cross connecting rod 10. The end of the first mounting shaft 8 has a first cross sliding slot, and one end of the cross connecting rod 10 is slidably installed in the first cross sliding slot. The opposite surfaces of the cross connecting rod 10 and the first cross sliding slot are jointly provided with a compression spring 11. One end of the rotating shaft 9 has a second cross sliding slot, and the other end of the cross connecting rod 10 extends into the second cross sliding slot. The outer wall of the cross connecting rod 10 is fixedly sleeved with an operating ring 12.

[0026] Through the above structure, between the first mounting shaft 8 and the rotating shaft 9, through the cross connecting rod 10 and the first and second cross sliding groove, it can ensure stable torque transmission, so that the rotating shaft 9 rotates synchronously with the hand massage roller 6, and through the operation ring 12, the user can manually pull the cross connecting rod 10, quickly release or restore the connection between the first mounting shaft 8 and the rotating shaft 9. When the cross connecting rod 10 is driven horizontally by the operation ring 12, the compression spring 11 can be compressed, and when the limiting of the operation ring 12 is released, the cross connecting rod 10 is driven to reset by the elastic action of the compression spring 11.

[0027] As shown in Figure 2 and Figure 3 , the first support plate 3 is provided with a transmission cavity, a rotating rod 13 is rotatably installed on the inner wall of one side of the transmission cavity, the other end of the rotating rod 13 is rotatably installed on the inner wall of the side of the mounting groove, the side of the mounting groove is provided with a first motor slot, and a control motor 15 for driving the rotating rod 13 to rotate is fixedly installed in the first motor slot. Specifically, the control motor 15 can be controlled by a PLC controller.

[0028] Through the above structure, when the control motor 15 is started, it can drive the rotating rod 13 to reciprocate by an appropriate angle (usually 0-30°), and when the rotating rod 13 rotates, it can drive the leg support plate 14 to rotate around the inner wall of the mounting groove. When the rotating rod 13 rotates clockwise, the leg support plate 14 is lifted upward, pushing the user's legs to bend and stretch the muscles on the back side of the legs. When it rotates counterclockwise, the leg support plate 14 falls back down, allowing the legs to stretch naturally. Through the reciprocating action, it can relieve the tension of the leg muscles caused by sitting for a long time, especially suitable for elderly users to promote lower limb blood circulation and prevent venous thrombosis.

[0029] As shown in Figure 2 , Figure 3 and Figure 4 , the linkage mechanism includes a first connecting shaft 17, a fixed block 16 is fixedly installed in the transmission cavity, the first connecting shaft 17 is rotatably installed on the fixed block 16, the first connecting shaft 17 and the peripheral outer wall of the rotating rod 13 are fixedly sleeved with a first bevel gear 18, the transmission cavity and the inner wall of the side of the rectangular cavity close to each other are provided with a second rotating hole, the second rotating hole is rotatably installed with a second connecting shaft 19, the second connecting shaft 19 and the peripheral outer wall of the first connecting shaft 17 are fixedly sleeved with a second bevel gear 20, and the second connecting shaft 19 and the peripheral outer wall of the rotating shaft 9 are fixedly sleeved with a third bevel gear 21.

[0030] By the above structure, when the rotating rod 13 rotates, the horizontal rotation of the rotating rod 13 is converted into the vertical rotation of the first connecting shaft 17 through the meshing of the two first bevel gears 18, then the first connecting shaft 17 drives the second connecting shaft 19 to rotate along the second rotating hole through the meshing of the second bevel gear 20 on the second connecting shaft 19, and then the power is transmitted to the rotating shaft 9 through the meshing of the second connecting shaft 19 and the third bevel gear 21 on the rotating shaft 9, and finally the hand massage roller 6 is driven to rotate through the connection of the cross connecting rod 10. This linkage design can realize the synchronous operation of "leg movement" and "hand massage" through the same control motor 15 without additional motor, which simplifies the device structure, reduces the production cost and energy consumption, and ensures the motion coordination of the two functions and improves the user's physiotherapy experience.

[0031] As shown in Figure 5 and Figure 6 The rotating mechanism includes a spline shaft 22, a connecting cavity is formed in the second support plate 4, one end of the spline shaft 22 is rotatably installed in the side inner wall of the lower cavity, the other end of the spline shaft 22 extends into the connecting cavity, a second motor groove is formed in the side inner wall of the lower cavity, and a driving motor 23 for driving the spline shaft 22 to rotate is fixedly installed in the second motor groove. Specifically, the driving motor 23 can be controlled by a PLC controller, a plurality of spline sleeves 24 are slidably sleeved on the peripheral outer wall of the spline shaft 22, and a plurality of circular plates 30 are fixedly sleeved on the peripheral outer wall of the plurality of spline sleeves 24.

[0032] By the above structure, the spline shaft 22 and the spline sleeve 24 in the rotating mechanism are in sliding sleeve connection, which not only ensures that the spline sleeve 24 can be driven to rotate synchronously (realizing torque transmission) when the spline shaft 22 rotates, but also allows the spline sleeve 24 to slide along the axial direction of the spline shaft 22, laying a foundation for subsequent adjustment of the distance between the circular plates 30. Specifically, when in use, the driving motor 23 is started to drive the spline shaft 22 to rotate stably, and then the plurality of circular plates 30 are driven to rotate synchronously through the spline sleeve 24. The plurality of circular plates 30 are distributed along the axial direction of the spline shaft 22 and can cover the acupoints of the user's waist, and the peripheral massage plates 32 can roll and press the muscles of the waist when the circular plates 30 rotate, relieving the waist pain, especially suitable for people who sit for a long time or have waist strain.

[0033] As shown in Figure 5 and Figure 6As shown, the spacing adjusting mechanism comprises an L-shaped plate 26, a first electric telescopic rod 27 is fixedly installed on the top inner wall of the lower cavity, specifically, the first electric telescopic rod 27 can be controlled through a PLC controller, the output end of the first electric telescopic rod 27 is fixedly connected with one side of the L-shaped plate 26, a plurality of limiting holes 28 are formed in the side of the L-shaped plate 26, a plurality of sliding shafts 29 are slidingly arranged in the plurality of limiting holes 28, and a U-shaped plate 25 is rotatably installed at the end of each of the plurality of sliding shafts 29. The plurality of U-shaped plates 25 are respectively fixedly sleeved on the circumferential outer wall of the plurality of spline sleeves 24.

[0034] Through the above structure, the spacing adjusting mechanism realizes flexible adjustment of the spacing of the circular plates 30 through the telescopic action of the first electric telescopic rod 27. When the first electric telescopic rod 27 is elongated, the L-shaped plate 26 is pushed to move downward, and when the first electric telescopic rod 27 is shortened, the L-shaped plate 26 is pulled to reset upward.

[0035] The plurality of limiting holes 28 formed in the side of the L-shaped plate 26 are in sliding cooperation with the sliding shafts 29, the end of the sliding shaft 29 is fixedly connected with the spline sleeve 24 through the U-shaped plate 25, and the spline sleeve 24 can slide along the spline shaft 22.

[0036] When the L-shaped plate 26 moves downward, the inner wall of the limiting hole 28 generates a horizontal pushing force to the middle of the sliding shaft 29, drives the two spline sleeves 24 to move close to the middle of the spline shaft 22, and reduces the spacing of the plurality of circular plates 30, which is suitable for users with narrower waists. When the L-shaped plate 26 moves upward, the limiting hole 28 generates a horizontal pulling force to the two sides of the sliding shaft 29, which increases the spacing of the circular plates 30, which is suitable for users with wider waists. This adjustment method does not need to be manually operated, and precise adjustment can be realized through electric control, which improves the adaptability of the device to users of different body types.

[0037] As shown in Figure 5 and Figure 7 The neck massage mechanism comprises two rotating plates 34, the two rotating plates 34 are rotatably installed on the opposite inner walls of the upper cavity, four second installation shafts 35 are rotatably installed on the opposite sides of the two rotating plates 34, and the circumferential outer wall of each of the four second installation shafts 35 is fixedly sleeved with a neck massage roller 36.

[0038] Through the above structure, the two rotating plates 34 in the upper cavity are rotatably installed on the opposite inner walls to form a symmetrical support structure, which ensures the stability during rotation. The four second installation shafts 35 rotatably installed on the opposite sides of the two rotating plates 34 uniformly distribute the four neck massage rollers 36. When the rotating plate 34 rotates, the neck massage roller 36 can make circular motion around the axis of the rotating plate 34, and its trajectory is highly consistent with the arc-shaped contour of the human neck, which avoids hard extrusion on the neck during the massage process.

[0039] Meanwhile, the neck massage roller 36 is rotatably connected to the rotating plate 34 through the second mounting shaft 35, and can rotate automatically when contacting with the skin of the neck, thereby converting the "rigid pressing" into "flexible rolling massage", reducing the stimulation to the skin and muscles of the neck, and being especially suitable for the elderly users with sensitive skin.

[0040] As shown in Figure 5 and Figure 6 , one side of the rotating plate 34 is fixedly installed with a round shaft 33, the other end of the round shaft 33 extends into a connecting cavity, the inner wall of the side of the connecting cavity is rotatably installed with a linkage shaft 37, the other end of the linkage shaft 37 penetrates into the lower cavity and is fixedly connected with the end of the spline shaft 22, the outer wall of the circumference of the linkage shaft 37 and the round shaft 33 is fixedly sleeved with a synchronous pulley 38, and the two synchronous pulleys 38 are jointly meshed with a synchronous belt 39.

[0041] Through the above structure, since one end of the linkage shaft 37 in the connecting cavity is fixedly connected with the end of the spline shaft 22, and the other end is rotatably installed in the inner wall of the connecting cavity, it can ensure that the spline shaft 22 can synchronously drive the linkage shaft 37 to stably rotate when the spline shaft 22 rotates, the linkage shaft 37 and the synchronous pulley 38 fixedly sleeved with the outer wall of the circumference are meshed and connected through the synchronous belt 39, forming a transmission path of "spline shaft 22→linkage shaft 37→synchronous pulley 38→synchronous belt 39→round shaft 33", which can ensure that the rotating speeds of the round shaft 33 and the linkage shaft 37 are consistent, avoiding that the massage strength of the neck massage roller 36 is large or small due to unstable rotating speed, and ensuring the uniformity of the neck massage. Meanwhile, the linkage design makes the "waist massage" and the "neck massage" share the same driving motor 23, and when the driving motor 23 is started, the round plate 30 of the waist and the neck massage roller 36 are synchronously operated, without the need to control two power sources respectively, thereby simplifying the operation process.

[0042] As shown in Figure 8 , the telescopic mechanism includes a second electric telescopic rod 31, the massage plate 32 is provided with an avoiding slot on one side, and the second electric telescopic rod 31 is arranged in the avoiding slot, one end of the second electric telescopic rod 31 is fixedly installed on the inner wall of the side of the groove, and the output end of the second electric telescopic rod 31 is fixedly connected with the inner wall of the side of the avoiding slot, and specifically, the second electric telescopic rod 31 can be individually controlled through a PLC controller.

[0043] Through the above structure, the groove provided on the circumference of the round plate 30 provides a sliding installation space for the massage plate 32, and the avoiding slot on one side of the massage plate 32 realizes the hidden installation of the second electric telescopic rod 31, avoiding that the telescopic rod protrudes from the surface of the massage plate 32 and directly contacts with the waist of the user, thereby preventing discomfort caused by pressing.

[0044] The second electric telescopic rod 31 is fixed at one end to the inner wall of the groove side part and is fixedly connected at the other end to the inner wall of the avoiding groove side part, and the telescopic action can directly drive the massage plate 32 to slide along the groove - when the telescopic rod is lengthened, the massage plate 32 protrudes outward, the pressing depth on the waist muscles is increased, and it is suitable for the waist strain population needing deep massage; when the telescopic rod is shortened, the massage plate 32 is retracted into the groove, the protrusion height is reduced, and it is suitable for the users with sensitive skin and low tolerance.

[0045] In addition, a plurality of massage plates 32 can be controlled independently to realize the combination of different protrusion heights, simulate the 'light and heavy alternation' method in manual massage, further improve the professionalism and pertinence of massage, and meet the physiotherapy needs of different users.

[0046] The working principle of the present application is as follows: when in use, the user first pulls the operating ring 12 to drive the cross connecting rod 10 to move horizontally, releases the clamping with the second cross sliding groove, rotates the hand massage roller 6 by 90 degrees and then sits on the chair cushion 1, resets the hand massage roller 6, loosens the limiting of the cross connecting rod 10, and through the elastic action of the compression spring 11, the cross connecting rod 10 can be reset and inserted into the second cross sliding groove, realizing the connecting function of the cross connecting rod 10 and the rotating shaft 9.

[0047] When the rotating rod 13 rotates, through the meshing action of the two first bevel gears 18, the first connecting shaft 17 can be driven to rotate synchronously, and then through the meshing action of the two second bevel gears 20, the second connecting shaft 19 can be driven to rotate synchronously, and finally through the meshing action of the two third bevel gears 21, the rotating shaft 9 can be driven to rotate, and through the connecting transmission of the cross connecting rod 10, the hand massage roller 6 can be driven to rotate reciprocally to massage the acupoints of the hands.

[0048] When in use, the user leans his back on the back cushion 2, drives the L-shaped plate 26 to move downward through the starting of the first electric telescopic rod 27, moves the two U-shaped plates 25 to the middle position through the limiting action of the plurality of limiting holes 28 and the sliding connection relationship between the spline sleeve 24 and the spline shaft 22, adjusts the positions of the plurality of circular plates 30, adjusts to the most comfortable state, drives the plurality of second electric telescopic rods 31 to move synchronously, adjusts the protrusion height of the massage plate 32, adjusts the massage depth, further improves the physiotherapy effect, drives the driving motor 23 to rotate the spline shaft 22, and then drives the plurality of spline sleeves 24 to rotate synchronously through the spline shaft 22, drives the circular plate 30 and the massage plate 32 to rotate synchronously through the plurality of spline sleeves 24, and massages the waist.
