[0027] Embodiment:

[0028] As Figures 1-3As shown, a multifunctional massage chair core comprises a massage piece 100 for massage connected with a shell 1; the massage piece 100 is in driving connection with a transmission device; the transmission device comprises a first transmission mechanism 200 for driving the massage piece 100 to perform kneading massage and a second transmission mechanism 300 for driving the massage piece 100 to perform knocking massage; the first transmission mechanism 200 comprises a kneading rotating shaft 240 and a deflection wheel 250; the kneading rotating shaft 240 is in driving connection with a massage motor 210; the kneading rotating shaft 240 is in rotational stop connection with the deflection wheel 250; the deflection wheel 250 comprises a connecting column 251 connected with the kneading rotating shaft 240 and eccentric and inclined; the massage piece 100 is sleeved on the connecting column 251 and driven by the kneading rotating shaft 240 to generate a kneading massage action under the deflection action of the connecting column 251.

[0029] The second transmission mechanism 300 comprises a knocking rotating shaft 340 in driving connection with a knocking motor 310; the knocking rotating shaft 340 is provided with an eccentric part 341; the eccentric part 341 is sleeved with a swing seat 350; the swing seat 350 is driven by the knocking rotating shaft 340 to swing along the circumference of the knocking rotating shaft 340 under the action of the eccentric part 341; the swing seat 350 is in movable connection with the massage piece 100 through a knocking connecting rod 360 and pushes and pulls the massage piece 100 to make the massage piece 100 rotate around the connecting column 251 to generate a knocking massage action when the swing seat 350 swings circumferentially.

[0030] The transmission device further comprises a third transmission mechanism 400 in driving connection with the second transmission mechanism 300; the second transmission mechanism 300 is in rotational connection with a first shaft and can rotate around the first shaft under the driving of the third transmission mechanism 400 to adjust the position of the massage piece 100; the first shaft is the kneading rotating shaft 240 or an axle arranged parallel to the kneading rotating shaft 240.

[0031] In the embodiment, the key technical features of the multifunctional massage chair core are described. The deflection wheel 250 refers to a component in rotational stop connection with the kneading rotating shaft 240 and generating eccentric and inclined motion, and its essence lies in the conversion of rotational motion to swinging motion through geometric bias. In practical application, the connecting column 251 is formed by integral injection molding to have an eccentric and inclined structure, which can be understood as that the axis of the connecting through hole in the middle of the connecting column 251 is arranged at an angle with the axis of the kneading rotating shaft, the eccentricity can be understood as that the axis of the connecting column 251 is arranged to deviate from the axis of the kneading rotating shaft 240, and the inclination can be understood as that the axis of the connecting column 251 has an angle with the axis of the kneading rotating shaft 240, and the angle is an acute angle; the connecting column 251 can be fixed on the kneading rotating shaft 240 through interference fit or key groove structure, or the connecting position of the kneading rotating shaft 240 and the deflection wheel 250 can be arranged as a flat head structure, and the rotational stop connection can be realized when the deflection wheel 250 is inserted on the kneading rotating shaft 240.

[0032] Further, the connecting column 251 refers to the columnar component on the wobble wheel 250 for sleeving the massage member 100, and the eccentric and inclined characteristics can be embodied by the inclined mounting hole on the connecting column 251. Specifically, a cylindrical cross-section design can be adopted, and the inclination can be achieved by adjusting the included angle between the hole center line and the center axis of the wobble wheel 250. The main purpose is to generate stable wobble force under the driving of the kneading rotating shaft 240.

[0033] Among them, the eccentric part 341 refers to the area on the knocking rotating shaft 340 that is offset from the axis to drive the swing seat 350. In practical application, a matched eccentric sleeve can be used, and the outer circle of the sleeve has a fixed offset from the axis of the knocking rotating shaft 340; or an eccentric boss is directly milled on the knocking rotating shaft 340, which is mainly to convert the rotary motion into the circumferential swing of the swing seat 350.

[0034] Further, the swing seat 350 refers to the connecting component sleeved on the eccentric part 341 and capable of swinging circumferentially. Specifically, a rolling bearing structure can be used to connect the eccentric part 341, wherein the bearing inner ring is clearance-fitted with the eccentric part 341 to reduce friction; or a self-lubricating sliding bearing is used to connect the eccentric part 341, and the graphite or polymer material is used to reduce wear, which is mainly to realize the stable swing of the swing seat 350 under the action of the eccentric part 341.

[0035] Further, the knocking connecting rod 360 refers to the rod connected with the massage member 100, which is used to transmit the circumferential swing of the swing seat 350 to the massage member 100. The knocking connecting rod 360 and the swing seat 350 are movably connected, and the pin shaft can be used to realize the rotational connection between the knocking connecting rod 360 and the swing seat 350. The knocking connecting rod 360 and the massage member 100 are also movably connected. Since the massage member 100 also performs kneading massage action, i.e., there is a wobble motion, the requirement for the freedom of motion is higher. The movable connection between the knocking connecting rod 360 and the massage member 100 can adopt ball head 361 joint movable connection to ensure sufficient freedom, or universal joint movable connection to ensure sufficient freedom.

[0036] The third transmission mechanism 400 refers to a device that is in transmission connection with the second transmission mechanism 300 and drives the second transmission mechanism 300 to rotate around the first shaft. In practical applications, an external gear system can be adopted, in which a pinion is driven by an independent motor to mesh with a large gear fixed on the second transmission mechanism 300; or a synchronous belt transmission mode can be adopted, in which torque is transmitted by pulleys and tensioning mechanisms. The main purpose is to realize the precise rotation of the second transmission mechanism 300 around the first shaft to adjust the position of the massage member 100. Further, the first shaft refers to the kneading rotating shaft 240 itself or an independent shaft arranged in parallel with the kneading rotating shaft 240. Specifically, part of the structure of the kneading rotating shaft 240 can be used as the rotation center; or an auxiliary shaft parallel to the kneading rotating shaft 240 can be arranged, which mainly provides a reference axis for the rotation of the second transmission mechanism 300. Thus, the embodiment realizes the adjustment of the position of the massage member 100 by making the second transmission mechanism 300 rotate around the first shaft under the drive of the third transmission mechanism 400, thereby adjusting the massage intensity. This design avoids the complexity of the traditional movable structure, integrates the intensity adjustment function into the transmission device, and does not need the overall displacement movement core, thereby significantly improving the structural reliability and durability while maintaining the kneading and knocking functions.

[0037] In the implementation process of the multifunctional massage chair core, the massage piece 100 is connected with the shell 1 and serves as a massage carrier, and receives multi-mode driving force through a transmission device to realize different massage functions. Among them, the transmission device is jointly composed of a first transmission mechanism 200, a second transmission mechanism 300 and a third transmission mechanism 400, and the overall operation is based on the cooperative matching of motor driving and mechanical transmission. Specifically, the massage motor 210 drives the kneading rotating shaft 240 to rotate, and the swing wheel 250 connected with the kneading rotating shaft 240 rotates, and since the swing wheel 250 contains an eccentric and inclined connecting column 251, the massage piece 100 is sleeved on the connecting column 251 and is subjected to the swing action to generate reciprocating motion, thereby forming a kneading massage action; this design eliminates the traditional connecting rod conversion link, makes the generation path of the kneading action more direct, and effectively avoids the problem of component wear caused by multi-stage transmission. Further, the knocking motor 310 drives the knocking rotating shaft 340 to rotate, and the eccentric part 341 on the knocking rotating shaft 340 drives the sleeved swing seat 350 to swing in the circumferential direction, and the swing seat 350 is movably connected with the massage piece 100 through the knocking connecting rod 360, and in the swing process, the massage piece 100 is pushed and pulled to rotate around the connecting column 251, thereby generating a knocking massage action; this process directly converts the rotary motion into swing, reduces the impact stress concentration, and ensures the stability of the knocking action. When the first transmission mechanism 200 and the second transmission mechanism work together, the massage piece 100 can simultaneously perform kneading massage and knocking massage; at the same time, the third transmission mechanism 400 is in transmission connection with the second transmission mechanism 300, and the second transmission mechanism 300 is driven to rotate around the first shaft to adjust the position of the massage piece 100, wherein the first shaft is the kneading rotating shaft 240 or an axial member arranged parallel to the kneading rotating shaft 240, thereby changing the contact angle of the massage piece 100 with the human body to realize force adjustment, without moving the whole core structure, thereby avoiding the fault risk caused by the movable components.

[0038] In an embodiment of the present application, the massage motor 210 is connected with the first mounting seat 220; the first mounting seat 220 is fixedly connected with the mounting plate 11 arranged on the shell 1; a worm is arranged on the output shaft of the massage motor 210; a first worm wheel 230 meshing with the worm is arranged on the first mounting seat 220; the first worm wheel 230 is rotationally connected with the kneading rotating shaft 240; the shell 1 is provided with a displacement slot 12 cooperating with the second transmission mechanism 300 to enable the second transmission mechanism 300 to be partially located in the displacement slot 12 when rotating around the first shaft.

[0039] The massage motor 210 is connected with the first mounting seat 220, that is, the massage motor 210 is fixedly installed on the first mounting seat 220, which can be achieved by bolt connection or welding, and the purpose is to provide independent support structure for the massage motor 210; the first mounting seat 220 is fixedly connected with the mounting plate 11 arranged on the shell 1, that is, the first mounting seat 220 is rigidly connected with the mounting plate 11 by fasteners, which can be fixed by screws or rivets, and the purpose is to provide a stable installation reference to resist displacement under dynamic working conditions; the output shaft of the massage motor 210 is provided with a worm, that is, a helical tooth-shaped transmission element is arranged at the end of the output shaft, and the worm can be an integral structure on the output shaft of the massage motor 210 or a worm sleeve structure fixed on the output shaft; the first mounting seat 220 is provided with a first worm gear 230 engaged with the worm, that is, a worm gear cooperating with the worm is installed on the first mounting seat 220; specifically, the rotation-stopping connection is a mechanical connection mode for preventing relative rotation between two rotating parts, which can be achieved by using a flat key, a spline or an interference fit, and the purpose is to ensure that there is no sliding loss and energy dissipation in the power transmission process. The shell 1 is provided with a displacement slot 12 cooperating with the second transmission mechanism 300, so that the second transmission mechanism 300 can be partially located in the displacement slot 12 when rotating around the first shaft, thereby reasonably utilizing the space and avoiding the massage chair core from being too large.

[0040] Specifically, the massage motor 210 is fixed on the first mounting seat 220, the first mounting seat 220 is rigidly connected to the shell 1 through the mounting plate 11, forming an independent and stable support system; the output shaft of the massage motor 210 drives the worm to rotate, the worm is engaged with the first worm gear 230 to transmit the rotary motion to the first worm gear 230, since the first worm gear 230 is rotation-stopping connected with the kneading rotating shaft 240, the kneading rotating shaft 240 is synchronously rotated, thereby driving the deflection wheel 250 to generate a kneading massage action; the engagement relationship of the worm and the worm gear converts the high-speed low-torque output of the motor into low-speed high-torque, which adapts to the intensity control requirement of the kneading massage, and the self-locking property of the worm inhibits the external reverse impact force, ensuring the durability and stability of the transmission relationship and the accuracy of power transmission during the movement of the core as a whole.

[0041] In an embodiment of the present application, the deflection wheel 250 includes a stop block 252 arranged at one end of a connecting column 251 and a deflection wheel gland 253 fixedly connected to the other end of the connecting column 251 away from the stop block 252, which prevents the massage member 100 from being separated from the connecting column 251; the massage member 100 is rotationally connected with the connecting column 251 through a connecting hole 101.

[0042] The stop block 252 refers to a fixed blocking structure arranged at one end of the connecting column 251, and is used for limiting the axial displacement of the massage member 100, and can adopt a flange, a check ring or an integrally formed protruding structure; the eccentric wheel pressing cover 253 refers to a cover-shaped part fixedly connected at the end of the connecting column 251 away from the stop block 252, and is used for preventing the massage member 100 from being separated from the connecting column 251, and can adopt a threaded connection, a buckle connection or a welded metal cover plate; the connecting hole 101 refers to a hole arranged on the massage member 100 and used for rotationally connecting with the connecting column 251, and can adopt a cylindrical hole, a bearing hole or a bushing structure.

[0043] Specifically, the scheme of the application forms a fixed block 252 at one end of the connecting column 251 to limit the axial displacement of the massage member 100 in this direction, and at the same time, the eccentric wheel pressing cover 253 provides closed constraint at the other end of the connecting column 251, and the two work together to firmly limit the massage member 100 within the axial range of the connecting column 251; on this basis, the massage member 100 is rotationally connected with the connecting column 251 through the connecting hole 101, and can still rotate freely under the axial constraint, so as to adapt to the eccentric tilting motion of the eccentric wheel 250 to realize the kneading massage action, and avoid axial sliding and separation caused by vibration or inertia.

[0044] In an embodiment of the utility model, the massage member 100 includes a connecting groove 102 movably connected with the knocking connecting rod 360; the knocking connecting rod 360 includes a ball head 361 matched with the connecting groove 102; the knocking connecting rod 360 is rotationally connected with the swing seat 350.

[0045] The connecting groove 102 refers to a recess structure arranged on the massage member 100 and used for accommodating the end of the knocking connecting rod 360, and the shape thereof is matched with the structure of the ball head 361, and the purpose thereof is to provide the movement freedom of the end of the knocking connecting rod 360 in multiple directions, and avoid stress concentration caused by rigid connection; the ball head 361 can be understood as a spherical protruding structure arranged at the end of the knocking connecting rod 360, and can be made of a metal ball head 361 or a plastic ball head 361, and the purpose thereof is to form a spherical pair with the connecting groove 102 to allow adaptive adjustment of the angle in multiple degrees of freedom and disperse dynamic load; the rotational connection refers to a rotatable connection between the knocking connecting rod 360 and the swing seat 350 through a pin shaft or a bearing, and can adopt a hinge connection, a universal joint connection or a spherical hinge connection, and the purpose thereof is to eliminate the rigid constraint between the connecting rod and the swing seat 350, so that the knocking connecting rod 360 can rotate freely according to the eccentric motion of the swing seat 350.

[0046] Specifically, the scheme of the application is through the cooperation of the connecting groove 102 and the ball head 361 and the rotary connection of the knocking connecting rod 360 and the swing seat 350, so that when the swing seat 350 is driven to swing circumferentially by the knocking rotating shaft 340, the knocking connecting rod 360 can adaptively adjust the angle according to the motion track of the swing seat 350; when the swing seat 350 pushes and pulls the knocking connecting rod 360, the ball head 361 slides in the connecting groove 102 and allows the massage piece 100 to rotate around the connecting column 251, thereby ensuring smooth transmission of the pushing and pulling force and avoiding interference phenomenon caused by deviation of the motion track, effectively relieving the stress concentration and jamming problem.

[0047] In an embodiment of the utility model, the massage piece 100 is provided with a first massage head 110 and a second massage head 120; the distance between the first massage head 110 and the kneading rotating shaft 240 is less than the distance between the second massage head 120 and the kneading rotating shaft 240; the massage piece 100 is provided with two.
