Description

Technical Field

[0001] This utility model relates to the field of percussion massager technology, and in particular to a percussion mechanism in a massager and its application in a massager. Background Technology

[0002] In modern life, people often experience muscle fatigue and soreness due to prolonged desk work and lack of exercise. To alleviate these discomforts, massage and wellness equipment has gradually gained popularity, with mechanisms featuring tapping functions being widely used in the massage and wellness field. These tapping mechanisms, by simulating manual tapping motions, can effectively promote blood circulation, relax muscles, and reduce fatigue, and are therefore extensively used in various massage chairs, massage cushions, handheld massagers, and other products.

[0003] Most existing tapping mechanisms can only tap in a single direction, making it difficult to simulate diverse tapping angles that better suit the human body's needs. For example, when massaging the lower back, different parts of the body require different tapping angles, but existing tapping mechanisms struggle to adjust flexibly to these differences, failing to meet the personalized massage needs of users. Even those mechanisms that do have some angle adjustment capabilities often have complex adjustment structures, making them inconvenient to operate and increasing the difficulty of using the product and manufacturing costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a massager applicable to a tapping mechanism and its applications.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A tapping mechanism for a massager includes a base, a drive unit, and a tapping assembly. The drive unit includes a rotating shaft providing rotational power and an eccentric cam attached to the rotating shaft, the eccentric cam being configured to rotate eccentrically following the rotating shaft. The tapping assembly includes:

[0007] A pair of striking elements arranged axially spaced along the axis of rotation, the lower ends of the striking elements being movably sleeved on an eccentric cam; and

[0008] A yaw limiting rod is movably connected between the striking member and the base in a yaw-like manner. The yaw limiting rod is configured to restrict the striking member from rotating about the eccentric cam while allowing the striking member to move radially along the eccentric cam.

[0009] The pair of striking elements are connected by a striking plate to output tapping massage actions synchronously.

[0010] Furthermore, the tapping plate has a flexible cushioning element on the side facing the user.

[0011] Furthermore, the striking element includes a swing sleeve movably fitted onto the eccentric cam and a striking bracket disposed on top of the swing sleeve.

[0012] Furthermore, the yaw sleeve can move left and right and up and down by means of the eccentric cam, and the yaw limiting rod is configured to limit the left and right movement.

[0013] Furthermore, a rolling bearing is disposed between the sway sleeve and the eccentric cam.

[0014] Furthermore, the rotation axis of the eccentric cam is set off-center from the rotation axis of the rotating shaft.

[0015] Furthermore, the drive device also includes a motor, the output shaft of which is connected to the rotating shaft via a synchronous pulley transmission assembly.

[0016] Furthermore, the synchronous pulley drive assembly includes a drive pulley and a drive belt that is drively connected to the drive pulley.

[0017] A massager includes the aforementioned tapping mechanism, which is disposed at one or more locations on the waist, legs, and seat of the massager.

[0018] Furthermore, the tapping mechanism is attached to the massager via a rubber pad.

[0019] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects:

[0020] 1. The striking component of this utility model is equipped with two swing sleeves fitted onto an eccentric cam, and the swing sleeves can move left and right and up and down by means of the eccentric cam. The striking mechanism, through the cooperation of the eccentric cam and the swing sleeves, and the limitation of the swing angle of the swing sleeves by the swing limiting rod, enables the striking component to produce complex and controllable striking actions. Specifically, the swing sleeves can produce left and right swinging and up and down swinging actions by means of the eccentric cam, while the swing limiting rod can limit the left and right swinging actions according to actual needs, thereby achieving precise control of the striking action angle output by the striking plate and providing users with a better tapping massage experience.

[0021] 2. The massager of this utility model is equipped with the aforementioned tapping mechanism, which has multiple advantages. This tapping mechanism can simulate diverse tapping angles that conform to the needs of the human body, and it has a reasonable structural design, long service life, and high safety. By configuring such a tapping mechanism in one or more locations on the waist, legs, or seat of the massager, it can provide users with richer, more precise, and more comfortable tapping massage functions according to the massage needs of different parts of the body, meeting diverse massage needs and significantly improving the massage experience.

[0035] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0036] Please see Figure 1 , Figure 2 This utility model discloses a tapping mechanism for a massager, mainly used in various massager devices such as waist massagers, leg massagers, and seat massagers, aiming to provide users with a comfortable and effective massage experience. The tapping mechanism mainly consists of a base 100, a drive device 200, and a tapping component 300. The drive device 200 provides rotational power to the entire mechanism, and through the cooperation of the rotating shaft 210 and the eccentric cam 220, converts the rotational motion into the tapping action of the tapping component 300, realizing tapping massage on the user's body parts. Under the action of the yaw limiting rod 320, the tapping component 300 can move within a certain range, while ensuring the stability and controllability of the tapping action. The specific structure, connection method, and working principle of each component will be described in detail below.

[0037] Please see Figure 4 , Figure 5 The base 100 serves as the fundamental support component of the entire tapping mechanism, providing a platform for the installation and fixation of other components. The material of the base 100 can be selected according to actual needs, such as metal or plastic. In practical applications, the base 100 is typically connected to the main structure of the massager, ensuring that the tapping mechanism can be securely mounted on the massager. The motor 230 is the power source of the drive device 200, and its output shaft generates rotational power. The type of motor 230 can be selected according to actual needs, such as a DC motor or an AC motor. The power of the motor 230 also needs to be rationally configured according to the working requirements of the tapping mechanism to ensure sufficient power to drive the tapping assembly 300 to perform effective tapping massage actions. The synchronous pulley transmission assembly 600 includes a transmission pulley 610 and a transmission belt 620 that is connected to the transmission pulley 610. The output shaft of the motor 230 is connected to the rotating shaft 210 via the synchronous pulley transmission assembly 600. Specifically, a drive wheel 610 is mounted on the output shaft of the motor 230, and another drive wheel 610 is mounted on the rotating shaft 210. The two drive wheels 610 are connected by a drive belt 620. When the motor 230 is working, its output shaft drives the drive wheel 610 mounted on it to rotate. The drive wheel 610 transmits power to the drive wheel 610 on the rotating shaft 210 via the drive belt 620, thereby causing the rotating shaft 210 to rotate. The rotating shaft 210 is an important component in the drive device 200, and it rotates under the drive of the synchronous pulley transmission assembly 600. An eccentric cam 220 is attached to the rotating shaft 210 and configured to rotate with the rotating shaft 210 in an eccentric manner. The axis of rotation of the eccentric cam 220 is set off-center from the axis of rotation of the rotating shaft 210. This eccentric setting is key to achieving the specific movement of the striking assembly 300. When the shaft 210 rotates, the eccentric cam 220 will rotate eccentrically around its own axis of rotation, thereby generating a changing force. This force will act on the striking assembly 300, causing it to move accordingly.

[0038] Please see Figure 3 In this embodiment, the striking element 310 includes a swing sleeve movably fitted onto the eccentric cam 220 and a striking bracket 311 disposed on the top of the swing sleeve 312. A pair of striking elements 310 are arranged at intervals along the axial direction of the rotating shaft 210, and the lower end of the striking element 310 is movably fitted onto the eccentric cam 220. A rolling bearing 313 is disposed between the swing sleeve 312 and the eccentric cam 220. The rolling bearing 313 reduces the friction between the swing sleeve and the eccentric cam 220, allowing the swing sleeve 312 to move more smoothly on the eccentric cam 220. The swing sleeve 312 can move left and right and up and down via the eccentric cam 220. This multi-directional movement capability allows the striking element 310 to achieve more flexible movement. The striking bracket 311 is used to connect the swing sleeve and the striking plate 400 and plays a role in transmitting force during the striking process. The yaw limiting rod 320 plays a crucial role in the striking assembly 300. One end of it is hinged to the base 100 via a limiting pivot 330, and the other end is hinged to the striking element 310, specifically to the yaw sleeve 312. The yaw limiting rod 320 is configured to allow the striking element 310 to move radially along the eccentric cam 220 while restricting its rotation around the eccentric cam 220. In this embodiment, when the eccentric cam 220 rotates, the yaw sleeve 312 moves up and down and left and right under the action of the eccentric cam 220. However, due to the restriction of the yaw limiting rod 320, the yaw sleeve 312 can only move up and down within a certain angle range and cannot rotate freely around the eccentric cam 220. This design ensures that the movement trajectory of the striking element 310 is controllable and that its output striking action is effective, thereby enabling the striking plate 400 to accurately output the striking massage action. A pair of tapping elements 310 are connected by a tapping plate 400. The tapping plate 400 can be made of a material with a certain degree of elasticity and strength, such as plastic or rubber. The tapping plate 400 is configured to output tapping massage movements. When the eccentric cam 220 rotates, power is transmitted to the tapping plate 400 through the eccentric sleeve 312 and the tapping elements 310, enabling the tapping plate 400 to output tapping massage movements synchronously. A flexible buffer 500 is provided on the side of the tapping plate 400 facing the user. The flexible buffer 500 can be made of materials such as sponge or silicone. Its function is to buffer the impact of the tapping plate 400 on the user's body during tapping, making the massage more comfortable. It should be noted that in this embodiment, the tapping plate 400 is a single piece. In other embodiments, the tapping plate 400 can also be a separate piece, which can achieve synchronous or asynchronous tapping on the left and right sides to improve massage comfort.

[0039] Working principle: When the massager is started, the motor 230 starts working, and its output shaft drives the transmission wheel 610 mounted on it to rotate. The transmission wheel 610 transmits power to the transmission wheel 610 on the rotating shaft 210 through the transmission belt 620, thereby causing the rotating shaft 210 to rotate. The rotation of the rotating shaft 210 drives the eccentric cam 220 to rotate eccentrically.

[0040] Due to the eccentric setting of the eccentric cam 220, when it rotates, it generates a varying force on the eccentric sleeve 312 that is movably fitted onto it. This force causes the eccentric sleeve 312 to move up and down and left and right. The up and down movement of the eccentric sleeve 312 is transmitted to the striking plate 400 through the striking bracket 311, causing the striking plate 400 to produce an up and down striking action; the left and right movement of the eccentric sleeve 312 is limited to a certain angle range by the eccentric limiting rod 320, thus ensuring that the striking action of the striking plate 400 is stable and controllable. Throughout the operation, the presence of the rolling bearing 313 reduces the friction between the eccentric sleeve and the eccentric cam 220, improving the operating efficiency and stability of the mechanism. The flexible buffer 500 cushions the impact force of the striking when the striking plate 400 comes into contact with the user's body, making the massage more comfortable.

[0041] Please see Figure 6 This application also provides a massager using the aforementioned tapping mechanism. The tapping mechanism can be applied to multiple parts of the massager, and is disposed at one or more of the waist position 10, leg position 20, and seat position 30 of the massager. The specific structure and application of the massager are described in detail below using the waist position 10 as an example.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
