Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of shoulder and neck massagers, and particularly relates to a double-kneading massage machine core. BACKGROUND

[0002] At present, common shoulder and neck massagers can be divided into kneading massagers and beating massagers according to their functions. However, the existing kneading massagers and beating massagers generally only have a single function, that is, the kneading massager only has the function of kneading massage, and the beating massager only has the function of beating massage, which is difficult to meet the use requirements of users. Although some shoulder strap type massagers currently realize the two-in-one function of kneading and beating, the massagers with both kneading and beating functions have the problems of large size and poor massage effect. For example, the kneading and beating massage machine core disclosed in the invention patent application CN119074499A realizes the kneading massage action of the first massage head and the second massage head through a first transmission mechanism, and realizes the beating action of the first massage head on the back through a second transmission mechanism. The first transmission mechanism is driven through a plurality of gears, and the second transmission mechanism is driven through a gear to drive a multi-section belt. The whole transmission mechanism is complex in structure, needs a large installation space, causes the whole massage machine core to be large in size, and the beating massage action of the massage machine core is limited to the position close to the shoulder of the back, so the beating massage effect is limited and the user experience is poor. For another example, the invention prior patent CN222517260U discloses a kneading and beating massage machine core. The transmission mechanism of the massage machine core for realizing the beating and kneading massage actions is to set output shafts at both ends of the motor. One output shaft is used to realize the transmission of the kneading massage action, and the other output shaft is used to realize the transmission of the beating massage action. The invention prior patent also has the problems of complex transmission structure, large demand for installation space, and large size of the whole massage machine core. In addition, the existing massage machine cores with both kneading and beating functions generally have two groups of massage heads. One group is a biasing massage head used to realize the kneading and rotating massage, and the other group is a top rod massage head used to realize the clamping and relaxing massage effect in cooperation with the biasing massage head. Moreover, the beating action of the massage machine core can only be realized for one group of massage heads. For example, the invention CN119074499A realizes the beating action through the top rod massage head, and the invention CN222517260U realizes the beating action through the biasing massage head. The two groups of massage heads cannot realize both the kneading massage action and the beating massage action, the massage effect is limited, the user requirements cannot be met, and the massage experience is affected.

[0003] Therefore, the present application is developed based on the deep thinking and active research on the improvement of the structure design of the existing kneading and beating massage machine core. SUMMARY

[0034] As Figures 1 to 10 shown, the present application discloses a double-kneading and beating massage core, which comprises a core shell 1, a drive motor 2, a first transmission mechanism 3 with a kneading shaft 31, a second transmission mechanism 4 with a beating shaft 41, a swing mechanism 5, a first massage mechanism 6, a second massage mechanism 7, a beating mechanism 8 and a connecting rod mechanism 9.

[0036] The beating mechanism 8 comprises two second eccentric wheels 81, two first connecting rods 82 and two swing rods 83, the two second eccentric wheels 81 are symmetrically arranged at the two ends of the second transmission mechanism 4, one end of the two first connecting rods 82 is connected with the second eccentric wheel 81, and the other end is rotatably connected with one end of the swing rod 83, the other end of the two swing rods 83 is rotatably connected with the eccentric ball head 611 of the eccentric arm 61.

[0037] The connecting rod mechanism 9 has a second connecting rod 91, one end of the second connecting rod 91 is rotatably connected with the swing rod 83 or the first connecting rod 82, and the other end of the second connecting rod 91 is connected with the top rod 71, the bottom end of the top rod 71 is upwardly provided with a limiting groove 711, and the other end of the second connecting rod 91 is rotatably fixed in the limiting groove 711.

[0038] The double-kneading massage machine core of the present application runs, the driving motor 2 drives the first transmission mechanism 3 and the second transmission mechanism 4 to rotate, the kneading shaft 31 of the first transmission mechanism 3 drives the deflection mechanism 5 to rotate when rotating, the deflection ball head 611 of the deflection arm 61 is acted on by the deflection inclined surface 521 of the deflection wheel 52 and the connecting swing rod 83, so that the deflection arm 61 can perform kneading massage action when the kneading shaft 31 rotates; the present application innovatively opens the limiting groove 711 for the installation and movement of the second connecting rod 91 at the bottom of the top rod 71, the two ends of the second connecting rod 91 are connected with the top rod 71 and the swing rod 83 of the hammering mechanism 8 respectively, since the top rod 71 is sleeved on the first eccentric wheel 51, when the first eccentric wheel 51 rotates with the kneading shaft 31, the top rod 71 converts the rotary motion into the up-down linear motion under the joint constraint of the rotary driving force of the first eccentric wheel 51 and the bottom limiting groove 711 and the second connecting rod 91, so that the second massage head 72 on the top rod 71 cooperates with the first massage head 62, realizing the massage effect of clamping and relaxing. The hammering shaft 41 of the second transmission mechanism 4 is limited by the one-way limiting mechanism, when the driving motor 2 drives the hammering shaft 41 to rotate, the second eccentric wheel 81 at both ends of the hammering shaft 41 drives the first connecting rod 82 and the swing rod 83 to perform the forward and backward hammering action when rotating, and then the first massage head 62 on the deflection arm 61 and the second massage head 72 on the top rod 71 are acted on by the deflection ball head 611 and the second connecting rod 91, realizing kneading massage and hammering massage at the same time, improving the massage effect. When the driving motor 2 reverses, the hammering shaft 41 cannot rotate due to the limitation of the one-way limiting mechanism, that is, it cannot perform hammering massage, at this time, only has kneading action, without hammering action.

[0039] The present application innovatively connects the hammering mechanism 8 with the first massage mechanism 6 and the second massage mechanism 7 at the same time, so that the first massage mechanism 6 and the second massage mechanism 7 perform kneading and tension at the same time, and through the forward and reverse rotation of the driving motor 2, whether the first massage mechanism 6 and the second massage mechanism 7 perform hammering massage at the same time is controlled.

[0040] The first end of the driving motor 2 is connected with the first worm 21, and the first screw tooth 211 is arranged on the first worm 21. The first transmission mechanism 3 comprises a kneading shaft 31, a first worm wheel 32 meshing with the first screw tooth 211, a second worm 33 fixedly connected with the first worm wheel 32 and provided with a second screw tooth 331, and a second worm wheel 34 meshing with the second worm 33 and fixedly connected with the kneading shaft 31. The second transmission mechanism 4 comprises a beating shaft 41, a driving wheel 42, a passive wheel 43, a belt 44 and the one-way limiting mechanism. The driving wheel 42 is arranged on the first worm 21 and is arranged in a spaced manner with the first screw tooth 211. The passive wheel 43 is arranged in a spaced manner with the driving wheel 42 in correspondence. 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 beating shaft 41 is arranged in a spaced manner with the kneading shaft 31 and passes through the center of the passive wheel 43. The one-way limiting mechanism is connected with the beating shaft 41 and the passive wheel 43, and controls the one-way rotation of the beating shaft 41. The one-way output of the driving motor 2 can drive the deflection arm 61 to rotate and deflect simultaneously, and the kneading massage action is completed. According to the forward rotation or reverse rotation of the driving motor 2, whether the beating action is performed simultaneously with the kneading massage can be selected. The first transmission mechanism 3 realizes transmission through two sets of worm gears. The double-stage transmission formed by the two sets of worm gears can easily convert the high-speed rotation of the driving motor 2 into the low-speed large torque required by the deflection massage head, and realizes the intensity similar to that of human hand kneading. The two sets of worm gears adopt the layout of vertical different surfaces, which can realize super large transmission ratio while greatly reducing the volume of the multi-stage gear transmission structure of the same power, so that the massager can realize the design of small and portable, and achieve compact size and sufficient massage intensity. In addition, since the massager needs to be used at close range, the noise directly affects the experience. The worm gear meshing transmission adopted by the massager belongs to linear contact, and multiple teeth are involved in meshing at the same time. The transmission impact and vibration are small, the first transmission mechanism 3 can keep stable during transmission, the running noise can be controlled at a low level, and after being matched with a brushless motor, the noise can be further reduced to avoid noise interference during massage. The driving wheel 42 of the second transmission mechanism 4 is directly arranged on the first worm 21 connected with the driving motor 2, which omits the installation space of the transition part, and has simple structure, low assembly and maintenance cost. The second transmission mechanism 4 has no intermediate transmission link, and the power of the driving motor 2 is directly transmitted to the driving wheel 42, so that the transmission response is direct and the energy loss is small. The space occupation of the first transmission mechanism 3 and the second transmission mechanism 4 is extremely small, which can reduce the installation space as much as possible, so that the volume of the whole double-kneading-beating massage core is greatly reduced, and it is more convenient for users to carry.

[0041] The deflection arm 61 has a first ring 612 corresponding to the deflection wheel 52, the deflection ball head 611 is arranged at the bottom of the deflection ring 612, the top rod 71 has a second ring 712 sleeved on the first eccentric wheel 51, the second ring 712 is provided with a top rod arm 713 inclined upward, the limiting groove 711 is arranged on the bottom of one end of the second ring 712 and inclined upward, the limiting groove 711 is provided with shaft holes 714 penetrating through the left and right ends, and one end of the second connecting rod 91 is rotatably connected with the limiting groove 711 through the rotating shaft.

[0042] In the embodiment, the first connecting rod 82 of the beating mechanism 8 is provided with a shaft column 821 on the opposite side, and the bottom end of the second connecting rod 91 is sleeved on the shaft column 821, so that the first connecting rod 82 is rotatably connected with the beating mechanism.

[0043] In the embodiment, the bottom of the first ring 612 of the deflection arm 61 is provided with a joint 613 with a bushing, the top end of the deflection ball head 611 is provided with a plug column 614 corresponding to the bushing, and the bushing and the plug column 614 are provided with one or more adjusting holes, so that the distance between the deflection ball head 611 and the deflection arm 61 can be adjusted, the deflection ball head 611 and the joint 613 can be locked, and the overall structural strength is higher. The deflection ball head 611 of the deflection arm 61 can also be integrally formed. The top surface of the swing rod 83 is provided with a ball hole 831 corresponding to the deflection ball head 611, and the ball hole 831 of the swing rod 83 adopts a split structure to facilitate the installation of the deflection ball head 611.

[0044] 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 arranged 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.

[0045] 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 fixed 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, so that 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, realizing the transmission of the beating action. When the driving motor 2 drives the belt 44 to rotate reversely, the driven wheel 43 rotates counterclockwise, so that 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. At this time, only the kneading action is performed, and no beating action is performed. 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 produce. The first spring 45 and the shaft sleeve 46 are used as the one-way limiting mechanism in the present application, when the driving motor 2 rotates forward, the inner diameter of the first spring 45 is reduced and locked with the shaft sleeve 46, thereby driving the beating shaft 41 to rotate; when the driving motor 2 reverses, the inner diameter of the first spring 45 is expanded and idles, and the beating shaft 41 is stationary. Compared with the one-way bearing scheme, the one-way limiting mode of the first spring 45 and the shaft sleeve 46 has lower hardness and precision requirements for the beating shaft 41, is not easy to wear, and has smaller noise.

[0046] 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.
