Abstract
Description
Technical Field
[0001] The invention relates to the technical field of massage chairs, and in particular to a multifunctional massage movement. Background Art
[0002] Most of the single-movement or dual-movement massage chairs currently on the market use movements that focus on upper body massage, but are not comfortable for lower body massage. The lower body massage area is the buttocks and thighs. The characteristic of the buttocks is that the body weight presses down, the tension is large, and the massage is not easy to go deep, so a large force is required; the characteristic of the thigh area is that the load-bearing area is tight, so it is difficult for the massage head to extend, while the other parts of the thigh are lighter in weight, and are affected by individual differences and sitting postures, making it difficult to find the correct massage position, and the massage effect is difficult to meet the requirements. For this reason, a lower body massage movement is needed. Summary of the invention
[0003] The technical problem to be solved by the present invention is to provide a massage movement that can massage the lower body and realize various massage techniques by switching the driving motor forward and reverse, and can perform stable massage and can be raised and lowered and swung left and right by airbags for massage.
[0004] In order to achieve the above-mentioned purpose, the following technical scheme is adopted: a multifunctional massage movement, comprising a support plate, a driving motor and a kneading component, wherein the driving motor drives the kneading component, the kneading component comprises a first kneading component and a second kneading component, the first kneading component comprises a first kneading shaft, the first kneading shaft is provided with two first oblique seats, each of which is sleeved with a first kneading arm, the second kneading component comprises a second kneading shaft, the second kneading shaft is provided with two second oblique seats, each of which is sleeved with a second kneading arm, the kneading head on the first kneading arm and the kneading head on the second kneading arm are arranged on the support plate in parallel or staggered front and back, the first kneading shaft and the second kneading shaft A gear set is provided on one side of the first kneading shaft, and an anti-rotation ratchet mechanism is provided on the other side of the first kneading shaft and the second kneading shaft, the gear set includes a driving gear provided on the first kneading shaft and a passive gear provided on the second kneading shaft, the driving motor drives the driving gear, the driving gear is meshed with the passive gear, a forward and reverse reversing mechanism is provided between the passive gear and the second kneading shaft, the forward and reverse reversing mechanism enables the passive gear to rotate relative to the second kneading shaft, so as to realize the reversal of the second kneading arm and kneading in the same direction or opposite direction with the first kneading arm, the anti-rotation ratchet mechanism includes a slider sliding back and forth on the supporting plate and a toggle member provided on the first kneading shaft, the toggle member extends into the slider and toggle the slider back and forth to counteract the rotation direction of the second kneading shaft.
[0005] By adopting the above technical scheme, when the active gear drives the passive gear to rotate, a phase difference can be achieved between the first kneading axis and the second kneading axis. The first kneading arm and the second kneading arm can massage in the same direction when the motor is not switched forward and reverse, that is, the first kneading arm and the second kneading arm perform kneading actions synchronously. After the motor switches forward and reverse, it can be switched so that the first kneading arm and the second kneading arm knead in opposite directions respectively. Since the spacing between the first kneading arms on the first kneading axis is greater than the spacing between the second kneading arms on the second kneading axis, two massage techniques can be formed: A. The first kneading arm and the second kneading arm on the left side and the first kneading arm and the second kneading arm on the right side form a set of kneading separately; B. The first kneading arm and the second kneading arm on the left side and the first kneading arm on the right side form a set of kneading separately. The pinching arm and the second kneading arm simultaneously form a large kneading group, thereby increasing the massage technique. Since the massage movement is suitable for massaging the lower body, when the second kneading arm on the second kneading shaft continuously switches forward and reverse rotation to knead and massage in the same direction or in the opposite direction as the first kneading arm, the second oblique seat also continuously switches and bears a larger weight. When the oblique seat reaches the highest point, it is easy to cause the oblique seat to rotate when under pressure, thereby driving the second kneading shaft to rotate, thereby causing damage to the massage movement. The toggle piece of the anti-rotation ratchet mechanism to toggle the sliding block back and forth with the forward and reverse rotation of the first kneading shaft, the sliding block can always abut against the rotation direction of the second kneading shaft, so that the massage movement will not rotate when it bears a large weight of the lower body, thereby increasing the service life of the massage movement.
[0006] A multifunctional massage movement can be further configured as follows: a slide is provided on the support plate, the sliding block slides back and forth in the slide, a first limit block and a second limit block are provided on the sliding block, a toggle groove is provided in the first limit block, an anti-rotation gear is fixedly provided on the second kneading shaft, the toggle piece is toggled back and forth in the toggle groove as the first kneading shaft rotates forward and reversely to realize the up and down sliding of the slider, and the first limit block or the second limit block counteracts the rotation direction of the anti-rotation gear.
[0007] By adopting the above technical solution, the first kneading shaft rotates forwardly to cause the lever to shift the sliding block backward, and the anti-rotation gear abuts against the rear side and upper side of the first limit block. At this time, the tooth shape of the anti-rotation gear in the rotation direction can push the rear side of the first limit block so that it can rotate continuously. If the anti-rotation gear rotates, its tooth shape will abut against the upper side of the first limit block so that it cannot rotate. When the first kneading shaft is reversed, the toggle member shifts the sliding block forward. At this time, the tooth shape of the anti-rotation gear in the rotation direction can push the front side of the second limit block so that it can rotate continuously. If the anti-rotation gear rotates, its tooth shape will abut against the upper side of the second limit block so that it cannot rotate. Through the cooperation of the toggle member and the toggle groove, the sliding block can slide forward and backward with the forward and reverse rotation of the first kneading shaft and prevent the anti-rotation gear from rotating. The structure is reasonable.
[0008] A multifunctional massage movement can be further configured as follows: the toggle member includes a toggle rod portion extending into a toggle groove and a sleeve portion sleeved on a first kneading shaft, one side of the sleeve portion is provided with a first end face gear, and the other side of the sleeve portion is connected to a first bevel seat with an elastic member, the first kneading shaft is fixedly provided with a second end face gear, and the elastic member enables the first end face gear to always elastically abut against the second end face gear.
[0009] By adopting the above technical solution, the elastic member always elastically meshes the first end face gear with the second end face gear, so that the second end face gear can drive the first end face gear to rotate when it rotates forward or reversely. When the lever reaches the front or rear side of the toggle groove and conflicts with it, the toggle member will not continue to rotate due to the elastic meshing, and the second end face gear can only be shifted forward or backward by forward and reverse rotation. Through this structure, the forward and reverse rotation of the first kneading shaft can be converted into the forward and backward movement of the lever, thereby driving the sliding block to slide back and forth and counteract the rotation direction of the anti-rotation gear.
[0010] A multifunctional massage movement can be further configured as follows: the forward and reverse reversing mechanism includes an inner sleeve arranged between the passive gear and the second kneading shaft, the side wall of the inner sleeve is provided with a limiting protrusion, and the passive gear is provided with a limiting groove, and the limiting groove respectively contacts with the two side surfaces of the limiting protrusion to realize the switching of the kneading direction of the second kneading arm.
[0011] By adopting the above technical solution, the driving motor drives the first kneading shaft to drive the driving gear to rotate forward, and the first kneading shaft drives the passive gear to rotate through the driving gear. One side of the limiting protrusion of the inner sleeve conflicts with the limiting groove and is therefore driven to rotate forward at the same time. The first kneading arm and the second kneading arm can massage in the same direction when the motor is not switched to forward and reverse rotation, that is, the first kneading arm and the second kneading arm perform kneading and releasing actions synchronously. After the motor switches to reverse rotation, the passive gear also reverses accordingly, while the inner sleeve does not move. When the limiting groove of the passive gear conflicts with the other side of the limiting protrusion, there is a phase difference between the first kneading shaft and the second kneading shaft. When the first kneading arm on the first kneading shaft performs a "pinch" action, the second kneading arm on the second kneading shaft switches to a "release" action, and the kneading directions of the two are opposite at this time. If you want to make the massage, pinching and releasing actions of the first kneading arm and the second kneading arm the same in direction again, you only need to rotate the motor forward again to rotate the passive gear and change the conflicting position with the inner sleeve. When the passive gear rotates, the limiting groove and the limiting protrusion are in contact with each other. The delay during the conflict can be used to re-pinch and release massage in the same direction. The forward and reverse reversing mechanism can control the pinching and releasing directions of the first kneading arm and the second kneading arm. A through groove can be set in the limit groove to allow the second kneading shaft to pass through so as not to affect the rotation of the second kneading shaft. When the driven gear rotates forward or reversely, different sides of the limit protrusion will conflict with the limit groove. The structure is simple and reasonable. The inner sleeve can also be provided with a limit groove, and the driven gear can also be provided with a limit protrusion. The two can be interchanged according to the selection. The first limit surface and the second limit surface can be set on the limit groove. Two limiting surfaces, when the first limiting surface or the second limiting surface respectively contacts with the limiting protrusion, it can drive the second kneading shaft to rotate in the same direction or in the opposite direction. When switching between forward and reverse kneading, the passive gear has a phase difference of 180° from contacting the first limiting surface to contacting the second limiting surface after rotation. Therefore, switching between same-direction kneading or reverse kneading can be achieved, thereby making the massage method more diverse. At the same time, the rotation angle of the passive gear in the present application can have some deviation, and it is not necessary to rotate 180° to achieve the technical solution of the present application.
[0012] A multifunctional massage movement can be further configured as follows: a lifting mechanism is provided between the kneading component and the support plate, the lifting mechanism includes a lifting plate and an air bag provided between the lifting plate and the support plate, the driving motor, the first kneading component, the second kneading component, the gear set and the anti-rotation ratchet mechanism are all provided on the side of the lifting plate away from the air bag, and the air bag is extended and retracted to enable the lifting plate to be lifted and lowered.
[0013] By adopting the above technical solution, when the airbag expands, the lifting plate can be lifted, and the lifting plate thereby lifts the first kneading component and the second kneading component, thereby lifting the kneading component, so that the kneading component can be extended and massage the lower body of the human body.
[0014] A multifunctional massage movement can be further configured as follows: a pallet rotating frame is also provided between the pallet and the lifting plate, the pallet rotating frame is rotatably provided on the pallet, a lifting opening is provided in the pallet rotating frame, a guide protrusion is provided on the lifting plate, the guide protrusion extends into the lifting opening to achieve guiding sliding cooperation with the inner wall of the lifting opening, and when the lifting plate is subjected to an external force, the cooperation between the guide protrusion and the pallet rotating frame realizes an inclined swing between the pallet and the lifting plate.
[0015] By adopting the above technical scheme, the lifting plate can be provided with a guide protrusion extending into the lifting port so as to realize the sliding cooperation between the guide protrusion and the inner wall of the lifting port, so that the airbag can only play the role of lifting the lifting plate, and the airbag is arranged around the outer circumference of the support plate rotating frame. When the airbag is inflated, the lifting plate will be tilted due to people with different sitting postures and weights sitting on the lifting plate. When the lifting plate is subjected to the inclined external pressure, the guide protrusion can be cooperated with the support plate rotating frame to realize the inclined swing between the lifting plate and the support plate, and the inflation of the airbag can make the guide protrusion gradually rise from the lifting port, and when the airbag is deflated, the guide protrusion on the lifting plate gradually drops from the lifting port due to the dead weight of the human body, thereby realizing the lifting and lowering of the lifting plate, and because the guide protrusion of the lifting plate is always in sliding cooperation with the lifting port, even if the airbag is not inflated, the lifting plate can be subjected to the inclined tension. The cooperation between the guide protrusion and the support plate rotating frame can realize the inclined swing between the lifting plate and the support plate.
[0016] A multifunctional massage movement can be further configured as follows: a cavity is provided on one end of the guide protrusion facing the lifting port, the drive motor is placed in the cavity, at least two notches are provided on the lifting plate, at least two lifting blocks are provided on one end of the support plate rotating frame facing the lifting plate, and when the airbag retracts the lifting plate, the lifting blocks extend from the notches.
[0017] By adopting the above technical solution, the body of the driving motor can be installed at the bottom of the lifting plate, and the guide protrusion can be provided with a cavity so as to cover the outside of the driving motor, thereby protecting the driving motor. When the airbag is in an uninflated state, most of the lifting block is exposed from the notch, and when the airbag expands and pushes up the lifting plate, the lifting block retracts from the notch. The lifting block is arranged close to the guide protrusion, thereby achieving a stabilizing effect. At the same time, since only the lifting block is extended, a larger area can be reserved on the lifting plate to install the kneading component.
[0018] A multifunctional massage movement can be further configured as follows: the lifting port is located between two lifting blocks, the two lifting blocks are provided with a slide groove extending into the lifting port on one opposite side, and the guide protrusion is provided with a slider at both ends of the slide groove. The slider has the same shape as the slide groove and is used for guiding the guide protrusion to slide with the lifting port.
[0019] By adopting the above technical solution, the shapes of the slider and the slide groove can be set to a trapezoid, so that the guide protrusion is not easy to deviate and slip when the guide sliding cooperation with the lifting port is carried out, thereby making the guide sliding of the guide protrusion and the lifting port more stable.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the protection examples of the present invention.
[0047] Example: Figure 1-Figure 24 A multifunctional massage movement shown in the figure comprises a support plate 1, a driving motor 2 and a kneading component 3, wherein the driving motor 2 drives the kneading component 3, the kneading component 3 comprises a first kneading component 3A and a second kneading component 3B, the first kneading component 3A comprises a first kneading shaft 31, the first kneading shaft 31 is provided with two first oblique seats 32, each of the first oblique seats 32 is sleeved with a first kneading arm 33, the second kneading component 3B comprises a second kneading shaft 41, the second kneading shaft 41 is provided with two second oblique seats 42, each of the second oblique seats 42 is sleeved with a second kneading arm 43, the spacing between the first kneading arms 33 on the first kneading shaft is greater than the spacing between the second kneading arms 43 on the second kneading shaft 41, the kneading heads on the first kneading arms 33 and the kneading heads on the second kneading arms 43 are arranged on the support plate 1 in parallel or staggered front and back, so as to form two arrangement states: as Figure 1 As shown, in state 1, the massage heads of the four massage arms are arranged in parallel, one group on each side; Fig. 22 As shown, state two: massage heads of four massage arms, one group at the front and one group at the back.
[0048] like Figure 1 As shown, one side of the first kneading shaft and the second kneading shaft is provided with a gear set 5, and the other side of the first kneading shaft 31 and the second kneading shaft 41 is provided with an anti-rotation ratchet mechanism 8, as shown in FIG. Figure 2 as well as Figure 8-Figure 12 As shown, the gear set 5 includes a driving gear 51 arranged on the first kneading shaft 31 and a driven gear 52 arranged on the second kneading shaft 41. The driving motor 2 drives the driving gear 51, and the driving gear 51 is meshed with the driven gear 52. A forward and reverse reversing mechanism 9 is provided between the driven gear 52 and the second kneading shaft 41. The forward and reverse reversing mechanism 9 includes an inner sleeve 91 arranged between the driven gear 52 and the second kneading shaft 41. The side wall of the inner sleeve 91 is provided with a limiting protrusion 911. A limiting groove 521 is provided in the driven gear 52. The limiting groove 521 respectively contacts with the two side surfaces of the limiting protrusion 911 to realize the switching of the kneading direction of the second kneading arm 43. Figure 11-Figure 17 As shown, the second kneading arm 43 is reversed and kneads in the same direction or opposite direction as the first kneading arm 33. When the active gear 51 drives the passive gear 52 to rotate, a phase difference of 180° can be achieved between the first kneading shaft 31 and the second kneading shaft 41. Fig.11 , Fig.15 and Fig.16 As shown, the first kneading arm 33 and the second kneading arm 43 can massage in the same direction when the driving motor 2 is not switched to forward and reverse rotation, that is, the first kneading arm 33 and the second kneading arm 43 perform the kneading action synchronously. Fig.12 , Fig.13 and Fig.14 As shown, the first kneading arm 33 and the second kneading arm 43 can be switched to knead in opposite directions respectively. Since the spacing between the first kneading arms 33 on the first kneading shaft 31 is larger than the spacing between the second kneading arms 43 on the second kneading shaft 41, two massage techniques can be formed: A. The first kneading arm 33 and the second kneading arm 43 on the left side and the first kneading arm 33 and the second kneading arm 43 on the right side form a set of kneading separately; B. The first kneading arm 33 and the second kneading arm 43 on the left side and the first kneading arm 33 and the second kneading arm 43 on the right side simultaneously form a large kneading group, thereby increasing the massage techniques.
[0049] like Figure 2-Figure 7As shown, the anti-rotation ratchet mechanism 8 includes a sliding block 81 that slides forward and backward on the support plate 1 and a toggle member 82 provided on the first kneading shaft 31. The toggle member 82 extends into the sliding block 81 and toggle the sliding block 81 forward and backward to counter the rotation direction of the second kneading shaft 41. The support plate 1 is provided with a slideway 83. The sliding block 81 slides forward and backward in the slideway 83. The sliding block 81 is provided with a first limit block 811 and a second limit block 812. The first limit block 811 is provided with a toggle groove 813. The second kneading shaft 41 is fixed with an anti-rotation gear 411. The toggle member 82 is toggled forward and backward in the toggle groove 813 as the first kneading shaft 31 rotates forward and reversely to realize the sliding of the sliding block 81 up and down. The first limit block 811 or the second limit block 812 The limit block 812 is against the rotation direction of the anti-rotation gear 411, and the toggle member 82 includes a toggle rod portion 821 extending into the toggle groove 813 and a sleeve portion 822 sleeved on the first kneading shaft 31. The sleeve portion 822 is provided with a first end face gear 823 on one side, and an elastic member 824 is connected between the other side and the first inclined center seat 32. The first kneading shaft 31 is fixedly provided with a second end face gear 311, and the elastic member 824 makes the first end face gear 823 always elastically abut against the second end face gear 311. The elastic member 824 always elastically meshes the first end face gear 823 with the second end face gear 311, so that when the second end face gear 311 rotates forward or reversely, it can drive the first end face gear 823 to rotate accordingly. Figure 6 and Figure 7 As shown, when the lever portion 821 reaches the front side or the rear side of the toggle groove 813 and contacts it, the toggle member 82 will not continue to rotate due to the elastic meshing, and the second end face gear 311 can only make the toggle member 82 move forward or backward through positive and negative rotation. Through this structure, the positive and negative rotation of the first kneading shaft 31 can be converted into the forward and backward movement of the lever portion 821, thereby driving the sliding block 81 to slide forward and backward and counteract the rotation direction of the anti-rotation gear 411. Since this massage movement is suitable for lower body massage, when the second kneading arm 43 on the second kneading shaft 41 continuously switches positive and negative rotations to engage with the first kneading arm When kneading and massaging in the same or reverse direction 33, the second oblique seat 42 is also continuously switched and bears a large weight. When the second oblique seat 42 reaches the highest point, it is easy to cause the second oblique seat 42 to rotate when under pressure, thereby driving the second kneading shaft 41 to rotate, thereby causing damage to the massage movement. The toggle member 82 of the anti-rotation ratchet mechanism 8 toggles the sliding block 81 back and forth as the first kneading shaft 31 rotates forward and reversely, and the sliding block 81 can always abut against the rotation direction of the second kneading shaft 41, so that the massage movement will not rotate when bearing a large weight of the lower body, thereby increasing the service life of the massage movement.
[0050] like Figure 17-Figure 24As shown, a lifting mechanism 6 is provided between the kneading assembly 3 and the support plate 1, and the lifting mechanism 6 includes a lifting plate 61 and an airbag 7 provided between the lifting plate 61 and the support plate 1. The driving motor 2, the first kneading assembly 3A, the second kneading assembly 3B, the gear set 5 and the anti-rotation ratchet mechanism 8 are all provided on the side of the lifting plate away from the airbag 7. The kneading heads on the first kneading arm 33 and the kneading heads on the second kneading arm 43 are arranged on the lifting plate 61 in parallel or staggered front and back. The airbag 7 is telescopic to enable the lifting plate 61 to be lifted and lowered. A support plate rotating frame 71 is also provided between the support plate 1 and the lifting plate 61. The support plate rotating frame 71 is rotatably provided on the support plate 1. The support plate 1 is stepped, so that the lifting plate 61 and the airbag 7 always have one side limited by the support plate 1 to prevent displacement during movement. A lifting port 72 is provided in the support plate rotating frame 71. A guide protrusion 64 is provided on the lifting plate 61, and the guide protrusion 64 extends into the lifting port 72 to achieve guided sliding cooperation with the inner wall of the lifting port 72. The guide protrusion 64 is provided with a cavity 73 at one end facing the lifting port 72, and the drive motor 2 is placed in the cavity 73. At least two notches 62 are provided on the lifting plate 61, and at least two lifting blocks 63 are provided at one end of the support plate rotating frame 71 facing the lifting plate 61. When the airbag 7 retracts the lifting plate 61, the lifting block 63 extends out of the notch 62, and the lifting port 72 is located between the two lifting blocks 63. The two lifting blocks 63 are provided with a slide groove 721 extending into the lifting port 72 on one side opposite to the other. Slide blocks 641 are provided at both ends of the guide protrusion 64 facing the slide groove 721. The slide block 641 has the same shape as the slide groove 721 and is provided for guiding the guide protrusion 64 to slide with the lifting port 72. Fig. 22 As shown, the lifting plate 61 is subjected to external force and can be tilted and swung with the pallet 1 through the cooperation between the guide protrusion 64 and the pallet rotating frame 71. A walking component can also be set on the back of the pallet 1, and the pallet 1 can move up and down along the massage chair track through the walking component, thereby realizing massage from top to bottom or from bottom to top.
