Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Features of the embodiments described below may be combined with each other without conflict.

Referring to fig. 1 and 2, the utility model discloses a knocking mechanism of a massager, which is mainly applied to various massager devices, such as a waist massager, a leg massager, a seat massager and the like, and aims to provide comfortable and effective massage experience for users. The striking mechanism is mainly composed of a base 100, a driving device 200 and a striking assembly 300. The driving device 200 provides rotary power for the whole mechanism, and converts the rotary motion into the knocking action of the knocking assembly 300 through the cooperation of the rotating shaft 210 and the eccentric cam 220, so as to realize knocking massage on the body part of the user. The striking assembly 300 can move within a certain range under the action of the deflection limiting lever 320, and simultaneously ensures the stability and controllability of the striking motion. The specific structure, connection manner and operation principle of each component will be described in detail.

Referring to fig. 4 and 5, the base 100 serves as a base support member for the entire striking mechanism, providing a mounting and securing platform for other components. The material of the base 100 may be selected according to practical needs, such as metal, plastic, etc. In practice, the base 100 is typically connected to the main body structure of the massager, ensuring that the striking mechanism is securely mounted to the massager. The motor 230 is a power source of the driving device 200, and an output shaft thereof is capable of generating rotational power. The type of motor 230 may be selected according to practical needs, such as a dc motor, an ac motor, etc. The power level of the motor 230 also needs to be reasonably configured according to the operating requirements of the striking mechanism to ensure that sufficient power can be provided to drive the striking assembly 300 for effective striking massage action. The synchronizing wheel drive assembly 600 includes a drive wheel 610 and a drive belt 620 drivingly connected to the drive wheel 610. The output shaft of the motor 230 is in driving connection with the rotating shaft 210 through a synchronizing wheel driving assembly 600. Specifically, a driving wheel 610 is installed on the output shaft of the motor 230, a driving wheel 610 is also installed on the rotating shaft 210, and the two driving wheels 610 are connected through a driving belt 620. When the motor 230 operates, an output shaft thereof rotates the driving wheel 610 mounted thereon, and the driving wheel 610 transmits power to the driving wheel 610 on the rotating shaft 210 through the driving belt 620, thereby rotating the rotating shaft 210. The spindle 210 is an important component of the driving apparatus 200, and it is rotated by the synchromesh wheel transmission assembly 600. The eccentric cam 220 is attached to the rotation shaft 210 and is configured to eccentrically follow the rotation shaft 210. The rotational axis of the eccentric cam 220 is eccentrically disposed with respect to the rotational axis of the shaft 210, which is critical to achieving a specific motion of the tapping assembly 300. When the shaft 210 rotates, the eccentric cam 220 eccentrically rotates about its own axis of rotation, thereby generating a varying force that acts on the rapping assembly 300 to cause its corresponding movement.

Referring to fig. 3, in the present embodiment, the knocking device 310 includes a yaw sleeve movably sleeved on the eccentric cam 220 and a knocking bracket 311 disposed on top of the yaw sleeve 312. A pair of knocking members 310 are disposed at intervals along the axial direction of the rotation shaft 210, and the lower end portions of the knocking members 310 are movably coupled to the eccentric cams 220. Rolling bearings 313 are disposed between the eccentric cams 220 and the yaw sleeve 312, and the rolling bearings 313 can reduce friction between the yaw sleeve and the eccentric cams 220, so that the yaw sleeve 312 can move on the eccentric cams 220 more smoothly. The yaw sleeve 312 can move left and right and up and down by the eccentric cam 220, and the multi-directional movement capability enables the rapper 310 to move more flexibly. The striking bracket 311 is used to connect the swing case and the striking plate 400, and functions to transmit force during striking. The yaw limiting lever 320 plays a critical role in the tapping assembly 300. One end of which is hinged to the base 100 via a limit pivot 330 and the other end of which is hinged to the plexor member 310, and more particularly to the yaw sleeve 312. The deflection limiting lever 320 is configured to limit the rotation of the plexor 310 about the eccentric cam 220 while allowing the plexor 310 to move in the radial direction of the eccentric cam 220. In the present embodiment, when the eccentric cam 220 rotates, the eccentric cam 220 moves up and down and moves left and right, but due to the limitation of the eccentric limiting rod 320, the eccentric cam 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 trajectory of the plexor member 310 is controllable and that the output striking motion is effective, thereby enabling the striking plate 400 to accurately output the striking massage motion. The pair of knocking members 310 are connected by the knocking plate 400, and the knocking plate 400 may be made of a material having a certain elasticity and strength, such as plastic, rubber, etc. The striking plate 400 is configured to output a striking massage motion. When the eccentric cam 220 rotates, power is transmitted to the striking plate 400 through the deflection sleeve 312 and the striking member 310, so that the striking plate 400 can synchronously output the striking massage motion. The flexible buffer member 500 is arranged on one side of the knocking plate 400 facing to the user, and the flexible buffer member 500 can be made of sponge, silica gel and other materials, and has the function of buffering the impact force of the knocking plate 400 on the body of the user in the knocking process, so that the massage is more comfortable. It should be noted that, in this embodiment, the striking plate 400 is integrally disposed, and in other embodiments, the striking plate 400 may be separately disposed, so as to achieve left-right synchronous or asynchronous striking, thereby improving the massage comfort.

Principle of operation when the massager is started, the motor 230 starts to operate, and its output shaft drives the driving wheel 610 mounted thereon to rotate. The driving wheel 610 transmits power to the driving wheel 610 on the rotation shaft 210 through the driving belt 620, thereby rotating the rotation shaft 210. Rotation of the rotation shaft 210 drives the eccentric cam 220 to eccentrically rotate.

Due to the eccentric arrangement of the eccentric cam 220, a varying force is created on the deflection sleeve 312 over which the movable sleeve is sleeved as it rotates. This force will cause the yaw sleeve 312 to move up and down and side to side. The up-and-down movement of the deflection sleeve 312 is transmitted to the knocking plate 400 through the knocking bracket 311, so that the knocking plate 400 generates up-and-down knocking actions, and the left-and-right movement of the deflection sleeve 312 can only be performed within a certain angle range under the limitation of the deflection limiting rod 320, so that the knocking actions of the knocking plate 400 are ensured to be stable and controllable. The presence of the rolling bearing 313 reduces friction between the deflection sleeve and the eccentric cam 220 throughout operation, improving the operating efficiency and stability of the mechanism. The flexible buffer member 500 buffers the impact force of the striking when the striking plate 400 contacts with the body of the user, so that the massage is more comfortable.

Referring to fig. 6, the present application is also directed to a massage apparatus using the striking mechanism, which can be applied to a plurality of parts of the massage apparatus, and is disposed at one or more of the waist position 10, the leg position 20, and the seat position 30 of the massage apparatus. The specific structure and application of the massager will be described in detail below using the lumbar region 10 as an example.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
