[0039] This utility model proposes a massager, such as Figures 1 to 4As shown, the device includes a fixed housing 110, a drive unit 210, a rotating shaft 300, an output gear set 220, a one-way output unit, an eccentric wheel 400, a first massage component 610, an eccentric column 500, and a second massage component 620. The drive unit 210 is fixed to the fixed housing 110. The output gear set 220 is sleeved on the rotating shaft 300 and includes a first output gear 221 and a second output gear 222. The rotating shaft 300 is connected to the first output gear 221 via the one-way output unit. The eccentric wheel 400 is sleeved on the rotating shaft 300 and located on the side close to the first output gear 221. The first massage component 610 is sleeved on the eccentric wheel 400. The eccentric column 500 is fixedly connected to the second output gear 222 and located on the side away from the first output gear 221. The first end of the second massage component 620 is provided with a massage head, and the second end of the second massage component 620 is connected to the eccentric column 500 via a transmission rod assembly. The drive member 210 is capable of rotating in a first direction and a second direction. When the drive member 210 rotates in the first direction, the first massage member 610 oscillates eccentrically under the action of the eccentric wheel 400, and the second massage member 620 moves toward or away from the first massage member 610 under the action of the eccentric column 500. When moving in the second direction, the first massage member 610 stays at a set position, and the second massage member 620 moves toward or away from the first massage member 610 under the action of the eccentric column 500.

[0040] Specifically, the output gear set 220 includes a first output gear 221 and a second output gear 222 coaxially arranged. A rotating shaft 300 passes through the output gear set 220 and is connected to the first output gear 221 via a one-way output component. The second output gear 222 has no power transmission relationship with the rotating shaft 300. The one-way output component mainly functions to transmit power in a single line; that is, when the first output gear 221 rotates in one direction, it transmits power to the rotating shaft 300, causing the rotating shaft 300 to rotate in the same direction as the first output gear 221. However, when the first output gear 221 rotates in the opposite direction, the one-way output component no longer transmits power from the first output gear 221 to the rotating shaft 300. It can be understood that the one-way output component can be a one-way bearing or other structures that achieve one-way power transmission. The drive component 210 can be a motor or other power output components.

[0041] Taking a motor as an example, the drive member 210 can rotate in a first direction and a second direction, which means that the motor can provide power for forward and reverse rotation. When the drive member 210 rotates in the first direction, the power of the drive member 210 is transmitted to the output gear set 220. The first output gear 221 and the second output gear 222 of the output gear set 220 rotate in the same direction under the action of the drive member 210. The first output gear 221 is connected to the rotating shaft 300 through a one-way bearing. At this time, the first output gear 221 can transmit power to the rotating shaft 300, so that the rotating shaft 300 and the first output gear 221 rotate synchronously. Since the rotating shaft 300 is also fitted with an eccentric wheel 400, the rotating shaft 300 drives the eccentric wheel 400 to move synchronously. Since the first massage member 610 is fitted on the eccentric wheel 400 and can rotate relative to the eccentric wheel 400, the first massage member 610 performs an oscillating action under the action of the eccentric wheel 400. Since the eccentric column 500 is mounted on the second output gear 222, the eccentric column 500 and the second output gear 222 can move synchronously during the rotation of the second output gear 222. Because the eccentric column 500 is eccentrically positioned relative to the second output gear 222, it can provide the power for eccentric oscillation. The eccentric column 500 is connected to the second massage element 620 via a transmission rod assembly, allowing the second massage element 620 to oscillate towards or away from the first massage element 610. When the drive member 210 rotates in the second direction, its power is transmitted to the output gear assembly 220. Since the first output gear 221 is connected to the rotating shaft 300 via a one-way bearing, its power cannot be transmitted to the rotating shaft 300, and the rotating shaft 300 remains stationary. At this time, the eccentric wheel 400 mounted on the rotating shaft 300 also remains stationary, and the first massage element 610 mounted on the eccentric wheel 400 remains in a set position, not performing a massage operation. Since the second output gear 222 is rotating, the eccentric column 500 eccentrically set on the second output gear 222 can provide the power for eccentric oscillation. At this time, the second massage member 620 transmits the power to the second massage assembly through the transmission rod assembly via the eccentric column 500, so that the second massage assembly can move toward or away from the second massage member 620.

[0042] In other words, by controlling the forward or reverse rotation of the motor, the operation of the first massage element 610 can be controlled. However, the above operation will not affect the second massage element 620, which can always maintain a continuous working state. Furthermore, by stacking the massager's core components in this embodiment, the power output ends of the first massage element 610 and the second massage element 620 are located on both sides of the output gear set 220, and they are stacked along the axial direction of the rotation shaft 300. This can improve the power transmission efficiency and effectively reduce the thickness of the massager in the axial direction of the rotation shaft 300.

[0043] In some embodiments, a first slide groove 111 is provided on the fixed housing 110, and the transmission rod assembly includes a first connecting rod 710 and a first slider 720. The first slider 720 is placed in the first slide groove 111. The first end of the first connecting rod 710 is rotatably connected to the eccentric column 500, the second end of the first connecting rod 710 is rotatably connected to the first end of the first slider 720 along axis A, and the second end of the first slider 720 is rotatably connected to the second end of the second massage member 620 along axis B.

[0044] Specifically, the fixed housing 110 is provided with a first slide groove 111, which is set approximately along the width direction of the massager (i.e., the Y direction shown in the figure). The eccentric column 500 and the second massage element 620 transmit power through a transmission rod assembly, which includes a first connecting rod 710 and a first slider 720. The first slider 720 is placed in the first slide groove 111. The first end of the first connecting rod 710 is rotatably connected to the eccentric column 500, that is, the first end of the first connecting rod 710 is rotatably connected to the eccentric column 500 by being sleeved on the eccentric column 500. The second end of the first connecting rod 710 is rotatably connected to the first end of the first slider 720 along axis A. The first connecting rod 710 and the first slider 720 are rotatably connected, that is, the first connecting rod 710 and the first slider 720 rotate around axis A. The second end of the first slider 720 is rotatably connected to the second end of the second massage element 620 along axis B, that is, the second end of the first slider 720 and the second end of the second massage element 620 are rotatably connected through a first rotating shaft 730.

[0045] Under the action of the drive component 210, the eccentric column 500 transmits power to the first connecting rod 710. The first slider 720 reciprocates along the first slide groove 111 under the action of the first connecting rod 710, thereby driving the second massage component 620 to swing along the axis B, so that the second massage component 620 presents a swinging motion that approaches or moves away from the first massage component 610.

[0046] In some embodiments, a second rotating shaft 740 is also included. The second rotating shaft 740 is placed in the first sliding groove 111. The second massage member 620 is provided with a second sliding groove 621. The second rotating shaft 740 passes through the second sliding groove 621 and is fixedly connected to the fixed housing 110.

[0047] Specifically, to enable the second massage element 620 to move closer to or further away from the first massage element 610, a second groove 621 is provided on the body of the second massage element 620. The second groove 621 is provided along the extending direction of the second massage element 620 and can be a straight groove or an arc groove, the specific shape of which is set according to actual needs. The second rotating shaft 740 passes through the second groove 621, is located in the first groove 111, and is fixedly connected to the fixed housing 110. When the drive member 210 moves, the eccentric column 500 transmits power to the first connecting rod 710, and the first connecting rod 710 transmits power to the first slider 720. As the first slider 720 reciprocates along the first groove 111, it drives the second massage element 620 to move. Under the push of the first slider 720 and the limiting effect of the second rotating shaft 740, the second massage element 620 can move closer to or further away from the first massage element 610. By setting the above transmission method, the second massage member 620 can be effectively confined to swing within the second slide groove 621, and one end of the second massage member 620 moves under the action of the first slider 720. That is to say, during the swinging process, the end of the second massage member 620 connected to the first slider 720 is always restricted by the first slider 720 and will not be higher or lower than the first slider 720, which can effectively control the size of the massager in the thickness direction.

[0048] In some specific embodiments, axis A and eccentric column 500 are arranged in parallel, and axis B is arranged in parallel with the first rotating shaft 730. This arrangement improves power transmission efficiency and avoids power jamming during transmission. It also reduces noise during massage and ensures smooth operation.

[0049] In some specific embodiments, a fixed bracket 120 is also included, which is fixedly connected to the fixed housing 110, and the fixed bracket 120 and the fixed housing 110 define the movement space of the first slider 720.

[0050] Specifically, to reduce manufacturing and assembly difficulties and improve assembly efficiency, the first slider 720 is not completely placed within the first slide groove 111, but partially protrudes from the first slide groove 111. That is, the first slider 720 is set as a boss, so that part of the structure of the first slider 720 is placed within the first slide groove 111 and slides and engages with the first slide groove 111, while some parts protrude from the first slide groove 111, which facilitates its assembly. However, although this method is convenient for processing and assembly, it is easy for the first slider 720 to detach from the first slide groove 111, affecting the reliability of the movement. Therefore, a fixed bracket 120 is also provided, which is fastened to the top of the first slider 720 and fixedly connected to the fixed housing 110. The fixed housing 110 and the fixed bracket 120 define an active space, so that the first slider 720 can slide smoothly during the movement without detaching from the first slide groove 111, thereby improving the reliability of the massager device.

[0051] In some embodiments, the first slider 720 is provided with a receiving hole 721 on the side facing the first groove 111, the second end of the second massage member 620 is placed in the receiving hole 721, and the second end of the second massage member 620 is rotatably connected to the first slider 720 through the first rotating shaft 730.

[0052] Specifically, the first slider 720 has a receiving hole 721 on the side facing the first slide groove 111. The size of the receiving hole 721 is such that it can accommodate the second end of the second massage member 620, and the second end of the second massage member 620 will not protrude from the first slide groove 111 through the receiving hole 721, and the second massage member 620 will not interfere with the swinging motion. The second end of the second massage member 620 is placed in the receiving hole 721, and the second end of the second massage member 620 is rotatably connected to the first slider 720 through the first rotating shaft 730, that is, the first rotating shaft 730 is placed in the receiving hole 721 and fixedly connected to the first slider 720. With the above arrangement, the end of the second massage member 620 can always be located inside the first slider 720, making the structure more compact. The part of the receiving hole 721 that contacts the second massage member 620 can be set as arc-shaped, so that friction can be reduced and power transmission efficiency can be improved during the swinging motion of the second massage member 620.

[0053] In some embodiments, the system further includes a first transmission gear set 230, which includes a first spur gear 231 and a first worm gear 232 coaxially arranged. The first spur gear 231 meshes with a first output gear 221 and a second output gear 222, and the first worm gear 232 meshes with the worm of the drive member 210.

[0054] Specifically, both the first transmission gear set 230 and the output gear set 220 adopt a coaxial double gear configuration. The first transmission gear set 230 uses a coaxially configured first worm gear 232 and a first straight gear 231, while the output gear set 220 uses a coaxially configured first output gear 221 and a second output gear 222. The worm of the driving member 210 meshes with the first worm gear 232, and the first straight gear 231 simultaneously meshes with the first output gear 221 and the second output gear 222. This stacking method effectively reduces the size.

[0055] In some embodiments, the fixed housing 110 is further provided with a limiting groove 112, and the first massage member 610 is provided with a limiting post 611, which is disposed in the limiting groove 112.

[0056] Specifically, a limiting groove 112 is provided on the fixed housing 110, and the extension direction of the limiting groove 112 can be set according to actual needs. Under the drive of the eccentric wheel 400 and the limiting effect of the limiting groove 112, the first massage member 610 can swing along a set trajectory. This effectively avoids unnecessary swinging, thereby obtaining a more ideal massage trajectory.

[0057] In some embodiments, the massager includes two first massage members 610 and two second massage members 620, with the two first massage members 610 and the two second massage members 620 arranged symmetrically.

[0058] Specifically, the massager is a symmetrical structure about plane C, which is parallel to the YZ plane and passes through the midpoint of the massager in the X direction. In a standard, ideal usage state, plane C coincides with the sagittal plane of the human body. Two first massage elements 610 and two second massage elements 620 are symmetrically arranged about plane C. In use, the two first massage elements 610 act on the user's shoulders and neck, and the two second massage elements 620 act on the user's back area. When the drive unit 210 operates in mode one, it drives the first massage elements 610 and the second massage elements 620 to move simultaneously, allowing the two first massage elements 610 to move closer or further apart, thus creating a kneading massage in the shoulders and neck area. The first massage elements 610 and 620 on the same side can also move closer or further apart, creating a kneading massage on the shoulder and back on the same side. This allows the entire shoulder and back area to be kneaded and relaxed. When the drive unit 210 operates in mode two, the first massage element 610 remains at a set position, and the second massage element 620 can move towards or away from the first massage element 610. This allows the second massage element 620 to slide up and down on the back area, thus achieving a rolling massage of the back area. In this embodiment, the drive unit 210 is a dual-head motor with two output shafts. The extension direction of the two output shafts is perpendicular to plane C, and the two output shafts are symmetrically arranged about plane C. The drive unit 210 is positioned between the two second massage elements 620. The output shafts of the drive unit 210 provide power to the corresponding output gear sets 220, that is, the output shaft on the left provides power to the output gear set 220 on the left, and the output shaft on the right provides power to the output gear set 220 on the right.

[0059] In some embodiments, the extension direction of the first slide groove 111 is inclined relative to the plane C, and the distance between the first ends of the two first slide grooves 111 is greater than the distance between the second ends of the two first slide grooves 111. The first end of the first slide groove 111 is the end closer to the eccentric column 500, and the first end of the second slide groove 621 is the end away from the eccentric column 500.

[0060] Specifically, the first slide groove 111 is inclined relative to plane C. That is, the extension direction of the first slide groove 111 is not parallel to plane C, but forms a certain angle with it. The distance between the first ends of the first slide grooves 111 on both sides is greater than the distance between the second ends of the second slide grooves 621 on both sides. This arrangement ensures that when the second massage element 620 acts on the back, its massage trajectory is not straight up and down, but rather slides from near the middle of the back towards the outer side of the shoulder or moves from the outer side of the shoulder towards the middle of the back. The angle between the extension direction of the first slide groove 111 and plane C can be set based on statistical data of the extension direction of the trapezius muscle in the human back. Thus, during the movement of the second massage element 620 towards or away from the first massage element 610, it can massage along the direction of the trapezius muscle, thereby relieving the tension of the trapezius muscle.

[0061] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
