[Solution] The device includes a core case, a drive motor 2, a first rolling mechanism 3, a second rolling mechanism 4, a deflection and oscillating mechanism 5, two massage mechanisms, a tapping mechanism 8, and a linkage mechanism 9. The drive motor is connected to the two rolling mechanisms.

Description

Technical Field

[0001] The present invention relates to the technical field of neck and shoulder massagers, and particularly to a massage core that performs both kneading and tapping.

Background Art

[0002] Conventionally, commonly seen neck and shoulder massagers can be classified into massage machines that perform kneading and pinching and massage machines that perform tapping and hitting according to their functions. However, the conventional massage machines that perform kneading and pinching and the massage machines that perform tapping and hitting generally have only a single function. That is, the massage machine that performs kneading and pinching only has the function of kneading and pinching massage, and the massage machine that performs tapping and hitting only has the function of tapping and hitting massage. Therefore, it is difficult to meet the needs of users. However, currently, some shoulder belt-type massagers have achieved the integration of the two functions of kneading and pinching and tapping and hitting. However, there is a problem that the massage machine having the functions of kneading and pinching and tapping and hitting simultaneously is large in volume and has a poor massage effect.

[0003] For example, the application according to the invention of CN119074499A discloses a massage core that performs kneading and pinching and tapping and hitting. The massage core according to this realizes the massage operation of kneading and pinching by the first rolling mechanism for the first massage head and the second massage head, and realizes the operation of tapping the back by the first massage head by the second rolling mechanism. The first rolling mechanism rolls by a plurality of gears, and the second rolling mechanism drives the rolling of a plurality of belts by gears. The overall structure of the rolling mechanism is complex, and a relatively large mounting space is required. The volume of the entire massage core is relatively large. Moreover, since the massage operation of tapping and hitting by the massage core plays a role at a position close to the shoulder on the back, the massage effect of tapping and hitting is limited, and the user experience is relatively poor.

[0004] Furthermore, a previously filed invention, CN222517260U, discloses a massage core that performs kneading and rubbing, and tapping and striking. In this massage core, the rolling mechanism that realizes the tapping and striking and kneading and rubbing massage actions has output shafts installed at both ends of a motor. One output shaft is for realizing the kneading and rubbing massage motion, and the other output shaft is for realizing the tapping and striking massage motion. This invention also has the problem that the rolling configuration is complex, there is a large need for mounting space, and the overall volume of the massage core is relatively large. Conventionally, massage cores that simultaneously perform kneading and twisting functions, as well as tapping and striking, generally consist of two groups of massage heads. One group consists of a deflection-oscillating massage head, which is used to achieve rotational massage that combines kneading and twisting, while the other group consists of a push-rod massage head. By combining massage heads that perform up-and-down and deflection-oscillating movements, a pinching and releasing massage effect can be achieved. The tapping and striking actions performed by the massage core are only connected to one of the groups of massage heads. For example, the invention CN119074499A can achieve tapping and striking actions with a push-rod massage head, while the invention CN222517260U achieves tapping and striking actions with a deflection-oscillating massage head. Because the two groups of massage heads cannot simultaneously provide both kneading and kneading massage actions and tapping and striking massage actions, the massage effect is limited, failing to meet user needs and affecting the massage experience.

[0005] In light of this, this invention was developed through careful consideration and proactive improvement to address the various shortcomings and inconveniences resulting from the fact that the core structure of conventional massage devices, which involves kneading, rubbing, tapping, and striking, is not yet perfectly designed.

[0012] Furthermore, the one-way position limiting mechanism includes a first spring and a bearing sleeve, the bearing sleeve being mounted around the striking shaft and locked to the striking shaft by interference fit so that the two cannot rotate relative to each other, the first spring having one end fixed to the bearing sleeve and the other end fixed to the driven wheel, and when the drive motor is linked to rotate the drive wheel in the forward direction, the belt is linked to rotate the driven wheel in the clockwise direction, and the inner diameter of the first spring is reduced, locking the first spring and the bearing sleeve together, so that the bearing sleeve and the striking shaft move together, realizing rolling motion that performs striking and beating operations, and when the drive motor is linked to rotate the belt in the opposite direction, the driven wheel rotates in the counterclockwise direction, the inner diameter of the first spring is increased, and the first spring idles together with the driven wheel.

[0013] Furthermore, an elastic position limiting mechanism is provided in the core case at a position corresponding to the striking shaft. The elastic position limiting mechanism includes a movable position limiting plate and a second spring. One end of the second spring is installed in the core case. The movable position limiting plate has a spring column on its bottom surface for attaching the second spring. The movable position limiting plate has an arc-shaped groove on its front surface that corresponds to the striking shaft. The striking shaft is installed in the arc-shaped groove, and the elasticity of the second spring pushes the movable position limiting plate upward, allowing the movable position limiting plate to come into contact with the striking shaft.

[0016] Furthermore, the distance D1 between the two first massage heads located on the left and right is 50-150 mm, and the distance D2 between the two second massage heads located on the left and right is 50-110 mm. When the first massage head rotates to the furthest position away from the second massage head, the second massage head swings to its lowest point, at which point the distance between the first and second massage heads is at its maximum, and the first and second massage heads form a spread-out state. When the first massage head rotates to approach the second massage head, the second massage head swings to its furthest point, at which point the distance D3 between the first and second massage heads is at its minimum, and the first and second massage heads form a sandwiched state. The value of the distance D3 between the first and second massage heads is 15 mm ≤ D3 ≤ 80 mm, and the angle range between the push rod and the deflection swing arm is 30°-120°. [Effects of the Invention]

[0017] By adopting the above configuration, the massage core of this invention, which performs both kneading and tapping, is provided with a first rolling mechanism to link with the deflection oscillation massage mechanism. The first massage mechanism is driven to perform kneading and kneading massage actions, and as the first and second massage mechanisms move closer to or further apart from each other while massaging, a pinching and releasing massage effect can be achieved. The tapping mechanism is connected to one group of massage heads and also connected to another group of massage heads by a connecting mechanism. The tapping mechanism is driven by the second rolling mechanism, controlling whether the first and second massage mechanisms simultaneously perform tapping and tapping massages. A single drive motor provides bidirectional output (forward rotation / opposite rotation), which links with the deflection oscillation arm to rotate and perform deflection oscillation, completing both kneading and kneading massages. Simultaneously, by changing the direction of the drive motor, it is possible to additionally select tapping and tapping actions based on the kneading and kneading massage. In this invention, with novelty, the striking mechanism is simultaneously connected to the first and second massage mechanisms. The first and second massage mechanisms provide relaxation through kneading and rubbing, while the rotation of the drive motor in forward and reverse directions controls whether the first and second massage mechanisms simultaneously perform striking and rubbing massages. This significantly enhances the massage effect and improves the massage experience. [Brief explanation of the drawing]

Embodiments for Carrying Out the Invention

[0019] In order to further explain the technical solution according to the present invention, the present invention will be described in detail below with specific embodiments.

[0020] In the description of the present invention, it is necessary to understand that terms indicating directions and positional relationships such as "center", "vertical direction", "horizontal direction", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "tip", "bottom", "inside", "outside", etc. are for indicating directions and positional relationships in the drawings, and are only for simplifying the description of the present invention and are not intended to explicitly or implicitly indicate that a specific configuration must be had by such devices or elements or that the configuration and operation must be performed in a specific direction, and thus should not be understood as a limitation to the present invention. In the description of the present invention, unless otherwise specified, the meaning of "plural" is two or more.

[0021] As shown in Figures 1 to 10, the present invention discloses a massage core that performs both kneading and tapping, which includes a core case 1, a drive motor 2, a first rolling mechanism 3 having a kneading shaft 31, a second rolling mechanism 4 having a tapping shaft 41, a deflection and oscillating mechanism 5, a first massage mechanism 6, a second massage mechanism 7, a tapping mechanism 8, and a linkage mechanism 9.

[0022] The drive motor 2 is connected to the first rolling mechanism 3 and the second rolling mechanism 4, and the second rolling mechanism 4 is equipped with a one-way position limiting mechanism that restricts the striking shaft 41 to rotating in one direction, and the deflection oscillation mechanism 5 is fixedly installed on the left and right sides of the kneading shaft 31 of the first rolling mechanism 3, and the deflection oscillation mechanism 5 each includes a first eccentric wheel 51 and a deflection oscillation wheel 52, and a deflection oscillation slope 521 is formed between the deflection oscillation wheel 52 and the kneading shaft 31, and the two deflection oscillation mechanisms 5 have the first eccentric wheel 51 installed at the inner end and the deflection oscillation wheel 52 installed at the outer end, and the first massage mechanism 6 is deflection oscillation The second massage mechanism 7 has an arm 61 and a first massage head 62 installed on the deflection swing arm 61, the two deflection swing arms 61 are circumferentially arranged corresponding to the two deflection swing wheels 52 and one end of the deflection swing arm 61 abuts against the deflection swing slope 521, the deflection swing arm 61 has a deflection swing head 611 installed at the bottom, the second massage mechanism 7 includes a push rod 71 and a second massage head 72 installed on the push rod 71, the push rod 71 is circumferentially arranged corresponding to the first eccentric wheel 51 and the deflection swing arm 61 and the push rod 71 are installed in a staggered pattern in the front-rear direction of the massage core.

[0023] The striking mechanism 8 includes two second eccentric wheels 81, two first links 82, and two oscillating rods 83. The two second eccentric wheels 81 are symmetrically positioned at both ends of the second rolling mechanism 4. The two first links 82 have one end connected to the second eccentric wheels 81 and the other end rotatably connected to one end of the oscillating rod 83. The other ends of the two oscillating rods 83 are rotatably connected to the deflection oscillating heads 611 of the deflection oscillating arm 61.

[0024] The link mechanism 9 has a second link 91, one end of which is rotatably connected to the swing rod 83 or the first link 82, and the other end of which is connected to the push rod 71, the push rod 71 having a position limiting groove 711 at its bottom and the other end of the second link 91 rotatably fixed to the position limiting groove 711.

[0025] When the massage core that performs both kneading and tapping according to the present invention is in operation, the drive motor 2 causes the first rolling mechanism 3 and the second rolling mechanism 4 to rotate in conjunction, and when the kneading shaft 31 of the first rolling mechanism 3 rotates, the deflection oscillating mechanism 5 rotates in conjunction, and the deflection oscillating head 611 of the deflection oscillating arm 61, through the role of the oscillating rod 83 connected to it and the deflection oscillating slope 521 of the deflection oscillating wheel 52, can perform a massage operation in which the deflection oscillating arm 61 kneads and taps as the kneading shaft 31 rotates.

[0026] This invention is novel in that a position limiting groove 711 is provided at the bottom of the push rod 71 to accommodate the attachment and movement of the second link 91, and the second link 91 is connected at both ends to the push rod 71 and the oscillating rod 83 of the striking mechanism 8, respectively. Since the push rod 71 is mounted around the first eccentric wheel 51, when the first eccentric wheel 51 rotates together with the kneading shaft 31, the push rod 71 converts its rotational motion into vertical linear motion due to the driving force of the rotation by the first eccentric wheel 51 and the joint limiting by the bottom position limiting groove 711 and the second link 91, thereby achieving a pinching and releasing massage effect by combining the second massage head 72 and the first massage head 62 on the push rod 71. The striking shaft 41 of the second rolling mechanism 4 is restricted by the one-way position limiting mechanism and is linked to the drive motor 2 so that the striking shaft 41 rotates. When the second eccentric wheels 81 at both ends of the striking shaft 41 rotate, the first link 82 and the oscillating rod 83 move back and forth in conjunction to perform striking and beating actions. Through the deflection oscillating head 611 and the second link 91, they act as the first massage head 62 on the deflection oscillating arm 61 and the second massage head 72 on the push rod 71, realizing a kneading and kneading massage as well as a striking and beating massage, thereby enhancing the massage effect. When the drive motor 2 rotates in the opposite direction, the striking shaft 41 cannot rotate due to the one-way position limiting mechanism, meaning that it cannot perform a striking and beating massage. At this time, it only has a kneading and kneading action and does not perform a striking and beating action.

[0027] This invention offers novelty by simultaneously connecting the tapping mechanism 8 to the first massage mechanism 6 and the second massage mechanism 7. This allows the first massage mechanism 6 and the second massage mechanism 7 to relax through kneading and rubbing, while the rotation of the drive motor 2 in forward and opposite directions can control whether the first massage mechanism 6 and the second massage mechanism 7 perform tapping and striking massages simultaneously or not.

[0028] In this embodiment, one end of the drive motor 2 is connected to the first worm 21, and the first worm 21 is provided with first helical teeth 211. The first rolling mechanism 3 includes a kneading shaft 31, a first worm gear 32 that meshes with the first helical teeth 211, a second worm 33 that is fixedly connected to the first worm gear 32 and has second helical teeth 331, and a second worm gear 34 that meshes with the second worm 33, the second worm gear 34 being fixedly connected to the kneading shaft 31. The second rolling mechanism 4 includes a striking shaft 41, a drive wheel 42, a driven wheel 43, a belt 44, and the one-way position limiting mechanism. The drive wheel 42 is installed on the first worm 21 and spaced apart from the first helical teeth 211. The driven wheel 43 is installed spaced apart from the drive wheel 42. The belt 44 has one end circumferentially around the drive wheel 42 and the other end circumferentially around the driven wheel 43. The striking shaft 41 and the kneading shaft 31 are spaced apart and pass through the center of the driven wheel 43. The one-way position limiting mechanism is connected to the striking shaft 41 and the driven wheel 43 and controls the striking shaft 41 to rotate in one direction. In this invention, the one-way output of a single drive motor 2 is linked to simultaneously rotate the deflection swing arm 61 and perform a deflection swing operation, completing the kneading and massaging operation. By rotating the drive motor 2 in the forward or reverse direction, it is possible to select whether or not to perform kneading and rubbing massages, as well as tapping and striking actions. The first rolling mechanism 3 achieves rolling using two worm gears, enabling two levels of rolling. This allows the high-speed rotation of the drive motor 2 to be easily converted into the low-speed, high-torque required for the deflected oscillation of the massage head, achieving a strength similar to that of manual kneading and rubbing. By adopting a layout in which the axes of the two worm gears are positioned perpendicularly on different faces, a significantly larger rolling rate can be achieved. Furthermore, the volume is significantly smaller than that of a multi-stage gear system with the same power, enabling a small, portable design for the massage machine, while maintaining sufficient massage strength despite its compact size.

[0029] Furthermore, since massage machines need to be used at close range, the user experience is directly affected by the level of noise. In this invention, the meshing and rolling motion of the worm gear worm corresponds to line contact, and multiple teeth are connected to mesh simultaneously, resulting in less collision due to its own rolling motion, weaker vibration, and the ability to maintain balance when the first rolling mechanism 3 rolls, thus controlling the noise during movement to a relatively low level. When a brushless motor is attached, the noise can be further reduced, avoiding noise interference during massage. The drive wheel 42 of the second rolling mechanism 4 is directly installed on the first worm 21 connected to the drive motor 2, eliminating the need for space to install intermediate parts, simplifying the configuration, and reducing the costs incurred in assembly and maintenance. Since there are no intermediate rolling parts in the second rolling mechanism 4, power from the drive motor 2 is transmitted directly to the drive wheel 42, and the rolling response occurs directly, resulting in low energy consumption. The first rolling mechanism 3 and the second rolling mechanism 4 occupy an extremely small space, minimizing the required mounting space. As a result, the overall volume of the massage core, which performs both kneading and tapping, is significantly reduced, making it even more convenient for users to carry.

[0030] The deflection oscillating arm 61 has a first ring 612 corresponding to the deflection oscillating wheel 52, the deflection oscillating head 611 is installed at the bottom of the deflection oscillating ring 612, the push rod 71 has a second ring 712 that is circumferentially mounted on the first eccentric wheel 51, the push rod arm 713 is provided at an angle above the second ring 712, the position limiting groove 711 is installed at an angle above the bottom of one end of the push rod arm 713 that is close to the second ring 712, the position limiting groove 711 is provided with an axle hole 714 that passes through both ends located on the left and right, and the second link 91 has one end that is rotatably connected to the position limiting groove 711 by a rotating shaft.

[0031] In this embodiment, the striking mechanism 8 is provided with two first links 82 located on the left and right sides, each with a convex shaft rod 821 on the opposing side, and the second link 91 has its bottom portion circumferentially attached to the shaft rod 821, so that the first links 82 are rotatably connected to the striking mechanism.

[0032] In this embodiment, the deflection swing arm 61 is provided with a joint 613 having an insertion hole at the bottom of the first ring 612, and the deflection swing head 611 is provided with an insertion column 614 at its tip that is combined with the insertion hole, and the insertion hole and insertion column 614 have one or more adjustment holes, and in addition to being able to adjust the distance between the deflection swing head 611 and the deflection swing arm 611 by using the multiple adjustment holes, it is also possible to lock or fix the deflection swing head 611 and the joint 613, further increasing the overall strength of the structure. The deflection swing head 611 of the deflection swing arm 61 may also be constructed as an integrated unit. The swing rod 83 is provided with a spherical hole 831 corresponding to the deflection swing head 611 on its tip surface, and in order to conveniently attach the deflection swing head 611, it is adopted to construct the spherical hole 831 of the swing rod 83 as a separate unit.

[0033] The aforementioned one-way position limiting mechanism has several configurations. For example, one configuration involves installing a one-way bearing (also called a clutch) on the striking shaft 41, so that when the belt 44 rotates in the forward or reverse direction in conjunction with the drive motor 2, the one-way bearing does not move in the reverse direction, and only forward torque is output to the striking shaft 41. Alternatively, one configuration involves directly attaching a directional bearing to the driven wheel 43, so that when the driven wheel 43 rotates in the forward direction by the belt 44, the one-way bearing locks, transmitting power to the striking shaft 41. When the driven wheel 43 rotates in the reverse direction by the belt 44, the one-way bearing idles, and the striking shaft 41 comes to a standstill.

[0034] In this embodiment, the one-way position limiting mechanism includes a first spring 45 and a bearing sleeve 46. The bearing sleeve 46 is mounted around the striking shaft 41 and is locked to the striking shaft 41 by interference fit, preventing the two from rotating relative to each other. The first spring 45 has one end fixed to the bearing sleeve 46 and the other end fixed to the driven wheel 43. When the drive motor 2 causes the drive wheel 42 to rotate in the forward direction, the belt 44 causes the driven wheel 43 to rotate clockwise, reducing the inner diameter of the first spring 45. As the first spring 45 and the bearing sleeve 46 are locked together, the bearing sleeve 46 and the striking shaft 41 move in conjunction, realizing rolling motion that performs striking and beating actions. When the drive motor 2 causes the belt 44 to rotate in the opposite direction, the driven wheel 43 rotates counterclockwise, increasing the inner diameter of the first spring 45. The first spring 45 cannot idle together with the driven wheel 43, preventing the bearing sleeve 46 from rotating. In other words, it cannot perform tapping and beating massage. At this time, it only performs kneading and kneading movements, and not tapping or beating movements.

[0035] In this embodiment, employing the first spring 45 and the bearing sleeve 46 as a unidirectional position limiting mechanism results in relatively lower requirements for the hardness and precision of the striking shaft 41 compared to a unidirectional bearing, making the striking shaft 41 less susceptible to wear and less prone to noise generation. In this invention, a unidirectional position limiting mechanism in which the first spring 45 and the bearing sleeve 46 are integrated is preferred. When the drive motor 2 rotates in the forward direction, the inner diameter of the first spring 45 decreases, locking it with the bearing sleeve 46 and causing the striking shaft 41 to rotate in conjunction. When it rotates in the opposite direction, the inner diameter of the first spring 45 increases, causing it to idle and the striking shaft 41 to come to a stop. Compared to the unidirectional bearing technology, the unidirectional position limiting configuration using the first spring 45 and the bearing sleeve 46 further reduces the requirements for hardness and precision of the striking shaft 41, making it less susceptible to wear and even less noisy.

[0036] To further enhance the effect of restricting the position of the striking shaft 41 to one direction, an elastic position limiting mechanism is further provided in the core case 1 at a position corresponding to the striking shaft 41. The elastic position limiting mechanism includes a movable position limiting plate 47 and a second spring 48. One end of the second spring 48 is installed in the core case 1. The movable position limiting plate 47 has a spring column for attaching the second spring 48 on its bottom surface. An arc-shaped groove 471 corresponding to the striking shaft 41 is provided on the front surface of the movable position limiting plate 47. The striking shaft 41 is installed in the arc-shaped groove 471.
