Day after day, it is inevitable that many people will suffer from cervical spondylosis and periarthritis of the shoulder. A shoulder strap massager for massaging the shoulder and neck has emerged as the times require. The shoulder strap massager is mainly used for massaging the shoulder and neck of the user. When in use, the driving device provides mechanical kinetic energy for the massage mechanism, so that the massage mechanism can rotate, swing, vibrate, and knock in a regular manner to relax the user, improve blood circulation in the shoulder and neck, relieve muscle stiffness and pain in the shoulder and neck, and the like.

[0003] At present, the shoulder strap type massager can be divided into kneading massagers and pounding massagers according to its function.

For another example, the rubbing and pounding massage machine core disclosed in the prior art of CN222517260U realizes the transmission mechanism of the pounding and rubbing massage action through the output shafts arranged at both ends of the motor, one output shaft is used to realize the transmission of the rubbing massage action, and the other output shaft is used to realize the transmission of the knocking massage action.

DETAILED DESCRIPTION

[0029] In order to further explain the technical scheme of the application, the application will be described in detail below through specific embodiments.

[0030] In the description of the present application, it needs to be understood that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore cannot be understood as a limitation on the present application. In the description of the present application, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0031] As shown in Figures 1 to 9 The present application discloses a kneading and pounding massage movement core, which comprises a movement core shell 1, a driving motor 2, a first transmission mechanism 3 with a kneading shaft 31, a second transmission mechanism 4 with a pounding shaft 41, a deflection mechanism 5, a massage mechanism 6 and a pounding mechanism 7.

[0032] The driving motor 2 is arranged in the movement core shell 1, one end of the driving motor 2 is connected with a first worm 21, and the first worm 21 is provided with a first helical tooth 211.

[0033] The first transmission mechanism 3 comprises the kneading shaft 31, a first worm wheel 32 engaged with the first helical tooth 211, a second worm 33 fixedly connected with the first worm wheel 32 and provided with a second helical tooth 331, and a second worm wheel 34 engaged with the second worm 33, wherein the second worm wheel 34 is fixedly connected with the kneading shaft 31.

[0034] The second transmission mechanism 4 comprises the pounding shaft 41, a driving wheel 42, a passive wheel 43, a belt 44 and a one-way limiting mechanism, wherein the driving wheel 42 is arranged on the first worm 21 and is arranged in a spaced manner with the first helical tooth 211, the passive wheel 43 is arranged in a spaced manner with the driving wheel 42, one end of the belt 44 is sleeved on the driving wheel 42, and the other end is sleeved on the passive wheel 43, the pounding shaft 41 is arranged in a spaced manner with the kneading shaft 31 and passes through the center of the passive wheel 43, and the one-way limiting mechanism is connected with the pounding shaft 41 and the passive wheel 43 to control the one-way rotation of the pounding shaft 41.

[0035] The deflection mechanism 5 comprises two deflection wheels 51 and two kneading and pounding swing arms 52, wherein the two deflection wheels 51 are fixedly arranged at the left and right ends of the kneading shaft 31, the two kneading and pounding swing arms 52 are symmetrically sleeved on the two deflection wheels 51, the bottom end of the kneading and pounding swing arm 52 is provided with a deflection ball head 521, and the end connected with the kneading and pounding swing arm 52 of the deflection wheel 51 forms a deflection inclined surface 511.

[0036] The massage mechanism 6 comprises two deflection massage heads 61, and the deflection massage head 61 is installed at the top end of the kneading and pounding swing arm 52.

[0037] The beating mechanism 7 has two beating eccentric wheels 71, two connecting rods 72 and two swing rods 73, the two beating eccentric wheels 71 are symmetrically sleeved on the two ends of the beating shaft 41, beating bearings are sleeved on the two sides of the beating shaft 41, the outer ends of the two beating eccentric wheels 71 are connected to one end of the two connecting rods 72, the other end of the two connecting rods 72 is rotatably connected to one end of the two swing rods 73, the other end of the two swing rods 73 is provided with a ball hole 731 corresponding to the eccentric swing ball head 521 of the kneading and beating swing arm 52, and the eccentric swing ball head 521 is installed in the ball hole 731.

[0038] When the kneading and beating massage machine core operates, the driving motor 2 drives the first worm 21 to rotate, the first worm 21 drives the first worm gear 32 meshed with the first spiral tooth 211 and the driving wheel 42 arranged on the first worm 21 to rotate when rotating, the first worm gear 32 drives the second worm 33 to rotate, the second worm 33 drives the second worm gear 34 meshed with the second spiral tooth 331 to rotate when rotating, the second worm gear 34 drives the kneading shaft 31 fixedly arranged together to rotate, the kneading shaft 31 drives the two eccentric wheels 51 to rotate, the eccentric swing inclined surface 511 of the eccentric wheel 51 applies a circumferential thrust and a radial component force to the end of the kneading and beating swing arm 52, and the connection of the eccentric swing ball head 521 of the bottom of the kneading and beating swing arm 52 to the swing rod 73 forms bidirectional limiting of the movement of the kneading and beating swing arm 52, that is, the movement of the kneading and beating swing arm along the axial direction of the eccentric wheel 51 is limited, and the swing amplitude and direction of the kneading and beating swing arm 52 are also limited, so that the kneading and beating swing arm cannot produce excessive angle swing or additional space offset. Under the limited state, the action of the kneading and beating swing arm 52 is driven by the eccentric swing inclined surface 511 and limited by the eccentric swing ball head 521 and the swing rod 73, the kneading and beating swing arm 52 swings periodically and reciprocally with a small amplitude and a fixed track with the sleeved part of the eccentric wheel 51 as the fulcrum, the eccentric swing ball head 521 rotates and displaces adaptively with the swing of the kneading and beating swing arm 52, drives the swing rod 73 to make a small amplitude circular motion in the horizontal range, and the reaction force of the swing rod 73 further maintains the stability of the swing of the kneading and beating swing arm 52, avoiding the action out of control caused by the impact force of the eccentric swing inclined surface 511.

[0039] At the same time, the driving wheel 42 drives the driven wheel 43 to rotate through the belt 44, the driven wheel 43 is limited by the one-way limiting mechanism, and the beating shaft 41 can only rotate in one direction, the beating shaft 41 drives the beating eccentric wheels 71 at the two ends of the beating shaft 41 to rotate when rotating, and further drives the connecting rod 72 and the swing rod 73 to make forward and backward knocking actions, and further acts on the eccentric swing massage head 61 of the kneading and beating swing arm 52, so that the kneading and beating massage is realized at the same time, the massage effect is improved. When the driving motor 2 drives the driving wheel 42 to rotate in the reverse direction, the beating shaft 41 cannot rotate due to the limitation of the one-way limiting mechanism, that is, the beating massage cannot be performed, at this time, only the kneading action exists, and the beating action does not exist.

[0040] The kneading and pounding massage mechanism of this invention can simultaneously drive the kneading and pounding arm 52 to rotate and oscillate through the unidirectional output of a single drive motor 2, thus completing the kneading and pounding massage action. Depending on whether the drive motor 2 rotates forward or backward, the pounding action can be selected to be performed simultaneously with the kneading and massaging action. The first transmission mechanism 3 achieves transmission through two sets of worm gears. The two sets of worm gears form a two-stage transmission, which can easily convert the high-speed rotation of the drive motor into the low-speed, high-torque required by the oscillating massage head 61, achieving a force similar to human hand kneading. The two sets of worm gears adopt a vertical, non-planar shaft layout, which achieves a large transmission ratio while greatly reducing its volume compared to a multi-stage gear transmission structure of the same power. This helps the massager to achieve a compact and portable design, making it small in size yet with sufficient massage force. Furthermore, since massagers require close-range use, noise levels directly impact the user experience. This invention employs a worm gear meshing transmission, which involves line contact and multiple teeth simultaneously engaging, resulting in minimal transmission impact and vibration. The first transmission mechanism 3 maintains smooth operation, keeping noise levels low. Combined with a brushless motor, this further reduces noise, preventing interference during massage. The drive wheel 42 of the second transmission mechanism 4 is directly mounted on the first worm gear 21 connecting to the drive motor 2, eliminating the need for intermediate components and simplifying the structure, assembly, and maintenance. The second transmission mechanism 4 eliminates intermediate transmission links, directly transmitting power from the drive motor 2 to the drive wheel 42, resulting in direct transmission response and minimal energy loss. The first and second transmission mechanisms 3 and 4 occupy minimal space, minimizing installation space and significantly reducing the overall size of the kneading massage mechanism, making it more portable.

[0041] To achieve a kneading and clamping massage effect, the massage mechanism also includes two push rods 62. A kneading swing arm 52 is installed at one end of each swing wheel 51, and a push rod 62 is installed at the other end of each swing wheel 51. The top of the swing massage head 61 is spaced apart from the top of the push rod 62. A movable limiting post 621 is provided at the bottom of the push rod 62. The mechanism housing 1 is provided with a guide groove 11 for the movable limiting post 621 to move. The movable limiting post 621 of the push rod 62 is movably installed in the guide groove 11. The kneading swing arm 52 can perform forward and reverse movements when the kneading shaft 31 rotates, which, together with the push rod 62, achieves a kneading and clamping massage effect.

[0042] To make the structure of the entire kneading and pounding massage mechanism more compact, the drive motor 2 is positioned between the left and right kneading and pounding arms 52. The bottom of the two push rods 62 is provided with a movable limiting post 621 protruding from the side facing the drive motor 2. The guide groove 11 is vertically set on the mechanism housing 1 on the side corresponding to the movable limiting post 621. Under the limiting action of the movable limiting post 621 of the push rod 62, the free end of the push rod 62 moves up and down in the guide groove 11. This structural design can not only ensure that the push rod 62 can move up and down, but also reduce space and make the layout of the entire kneading and pounding massage mechanism more compact.

[0043] The structure of the one-way limiting mechanism can be various, for example, a one-way bearing (also called a clutch) is arranged on the beating shaft 41, when the belt 44 is driven by the driving motor 2 to rotate forward or reversely, the one-way bearing filters the reverse movement, and only the forward torque is output to the beating shaft 41; or a one-way bearing is directly installed on the driven wheel 43, when the belt 44 drives the driven wheel 43 to rotate forward, the one-way bearing is locked, and the power is transmitted to the beating shaft 41, when the belt 44 drives the driven wheel 43 to rotate reversely, the one-way bearing idles, and the beating shaft 41 is stationary. In the embodiment, the one-way limiting mechanism comprises a first spring 45 and a shaft sleeve 46, the shaft sleeve 46 is sleeved on the beating shaft 41 and locked with the beating shaft 41 by interference fit, and the two do not rotate relative to each other, one end of the first spring 45 is fixedly installed on the shaft sleeve 46, and the other end of the first spring 45 is fixedly installed on the driven wheel 43, when the driving motor 2 drives the driving wheel 42 to rotate forward, the belt 44 drives the driven wheel 43 to rotate clockwise, the inner diameter of the first spring 45 is reduced, the first spring 45 is locked with the shaft sleeve 46, thereby driving the shaft sleeve 46 and the beating shaft 41 to move together, and the transmission of the beating action is realized; when the driving motor 2 drives the belt 44 to rotate reversely, the driven wheel 43 rotates counterclockwise, the inner diameter of the first spring 45 is increased, the first spring 45 idles with the driven wheel 43, and the shaft sleeve 46 cannot be driven to rotate, that is, the beating massage cannot be performed, and only the kneading action is performed without the beating action. Compared with the one-way bearing structure, the first spring 45 and the shaft sleeve 46 are used as the one-way limiting mechanism in the embodiment, the hardness and precision requirements of the beating shaft 41 of the present application are relatively low, the beating shaft 41 is not easy to wear, and noise is not easy to be generated.

[0044] In order to further improve the one-way limiting effect of the beating shaft 41, the machine core shell 1 is further provided with an elastic limiting mechanism corresponding to the position of the beating shaft 41, the elastic limiting mechanism comprises a movable limiting plate 47 and a second spring 48, one end of the second spring 48 is arranged on the machine core shell 1, the bottom surface of the movable limiting plate 47 is provided with a spring column for mounting the second spring 48, the top surface of the movable limiting plate 47 is provided with an arc-shaped groove 471 corresponding to the beating shaft 41, the beating shaft 41 is arranged on the arc-shaped groove 471, the movable limiting plate 47 is lifted upward by the elasticity of the second spring 48, so that the movable limiting plate 47 can abut against the beating shaft 41, and the beating shaft 41 is prevented from rotating reversely through the friction between the movable limiting plate 47 and the beating shaft 41.

[0045] In the embodiment, the distance D1 between the two left and right wobble massage heads 61 is 50-150 mm, and the distance D2 between the two left and right top rods 62 is 50-110 mm. When the wobble massage head 61 rotates to the farthest end of the top rod 62, the top rod 62 swings to the bottom end of the guide groove 11, at this time, the distance between the wobble massage head 61 and the top rod 62 is the largest, and the wobble massage head 61 and the top rod 62 form an open state. When the wobble massage head 61 rotates to the top rod 62, the top rod 62 swings to the top end of the guide groove 11, at this time, the distance between the wobble massage head 61 and the top rod 62 is the smallest, and the wobble massage head 61 and the top rod 62 form a clamping state. The distance D3 between the wobble massage head 61 and the closest end of the top rod 62 is 15≤D3≤80 mm.
