[0027] As shown in the figure, a pounding massager disclosed by the present utility model includes a housing body 3. A motor 8 is arranged inside the housing body 3. The motor 8 is in transmission connection with a drive shaft 12. Specifically, the output end of the motor 8 is connected with a first synchronous pulley 9. The first synchronous pulley 9 is in transmission with a second synchronous pulley 11 through a synchronous belt 10. The second synchronous pulley 11 is connected to the drive shaft 12. A cam 13 is connected to the drive shaft 12. It further includes a pounding arm 4. One end of the pounding arm 4 is rotatably arranged inside the housing body 3, and the other end extends out of the housing body and is provided with a pounding component. Specifically, the pounding component includes a first massage head 5 arranged at one end of the pounding arm 4. A swing arm 6 is rotatably arranged on the pounding arm 4. A second massage head 7 is arranged at one end of the swing arm 6. The pounding arm 4 is connected with the first massage head 5 through a fastener 30. The fastener 30 passes through a relief hole 31 on the swing arm 6. A first damping pad 28 is tightly pressed between the pounding arm 4 and the swing arm 6. A second damping pad 29 is tightly pressed between the swing arm 6 and the first massage head 5. By arranging the first and second damping pads, the feel of the swing of the swing arm 6 can be improved and damping positioning can be achieved after the swing arm 6 swings in place. By controlling the swing of the swing arm 6 to an appropriate angle, the position of the second massage head 7 can be adjusted, so as to adapt to the massage at different positions or the use of users with different body types, improving the flexibility of its use. At the same time, according to different use requirements, multiple massage heads can also be arranged on the swing arm 6. Of course, according to the use requirements, a detachable soft elastic ball sleeve 27 can be sleeved on the massage head, making the pounding massage softer. A spring 17 is connected between the housing body 3 and the pounding arm 4. The cam 13 can squeeze the pounding arm 4 to swing. Further, it also includes a shock-absorbing spring 18 arranged inside the housing body 3. The shock-absorbing spring 18 is tightly pressed between the pounding arm 4 and the housing body 3. By arranging the shock-absorbing spring 18, elastic buffering can be carried out on the swing of the pounding arm 4, making its movement smoother and reducing noise, enabling the pounding arm 4 to quickly reset and reducing the load of the motor 8. A first elastic buffer pad 14 is installed on the pounding arm 4. A second elastic buffer pad 15 that can cooperate with the first elastic buffer pad 14 is arranged on the housing body 3. When the pounding arm 4 swings downward, the first and second elastic buffer pads can cooperate with each other to provide a buffer and shock-absorbing effect. In addition, the pounding arm 4 is arranged in an arc shape, and the pounding arm 4 has an arc surface 16 that cooperates with the cam 13 in contact, which can make the contact and cooperation between the pounding arm 4 and the cam 13 smoother. A third elastic buffer pad 25 is arranged at the contact end of the pounding arm 4 that cooperates with the cam 13. The third elastic buffer pad 25 is made of a soft wear-resistant material. An elastic buffer ring 26 is sleeved on the outer ring of the cam 13. The elastic buffer ring 26 is made of a soft noise-reducing material. The two cooperate with each other to effectively achieve the impact force when the pounding arm 4 cooperates with the cam, making their cooperation softer and reducing the noise generated during operation, improving the user experience.Further, there are two arm - thumping members 4 arranged on the left and right sides. Correspondingly, there are also two cams 13. Both of the two cams 13 are connected to the drive shaft 12. A transmission groove 19 is formed on the cam 13. On the outer side wall of one side of the drive shaft 12, there are a first transmission pin 22 and a second transmission pin 23. The first transmission pin 22 and the second transmission pin 23 respectively press against the first transmission side surface 20 and the second transmission side surface of the transmission groove 19 on one of the cams. On the outer side wall of the other side of the drive shaft 12, there is a third transmission pin 24. The third transmission pin 24 can move in the transmission groove of the other cam 13 and press against any side surface of the transmission groove for transmission. By adopting the above - mentioned transmission structure, when the motor rotates forward or backward, the cam driven by the first and second transmission pins can drive the cam to rotate immediately by one of the transmission pins pressing against the transmission side surface, thereby driving the arm - thumping member 4 to swing. For the cam driven by the third transmission pin 24, only when the rotation direction of the motor is the same as that at the previous start, the third transmission pin 24 will immediately press against the transmission side surface in contact with it to drive the cam to rotate immediately and drive the arm - thumping member 4 to swing, realizing the synchronous swing of the two arm - thumping members. If the rotation direction of the motor is opposite to that at the previous start, the third transmission pin 24 will first swing in the transmission groove 19 until it presses against the other side transmission side surface, and then drive the cam to rotate. At this time, this cam will move slower than the other cam, thus realizing the asynchronous swing of the two arm - thumping members 4 at different heights, forming a rhythmic alternating thumping massage. In addition, the first transmission pin 22 and the second transmission pin 23 can also be of an integrated structure, but their length is longer than that of the third transmission pin 24, and the above - mentioned functions can also be realized. An external connecting member 2 is arranged on the outer housing 3. The external connecting member 2 can be connected to the strap 1, which can conveniently tie the massager to the part where hammering massage is needed.

[0028] The working principle of the present utility model is as follows: By controlling the start of the motor 8, through the synchronous belt transmission group for transmission, the drive shaft 12 is driven to rotate. The drive shaft 12 will drive the cam 13 to rotate. When the outer convex part of the cam 13 contacts the arm - thumping member 4, it will squeeze the arm - thumping member 4 to swing upward and stretch the spring 17. When the outer convex part of the cam 13 separates from the arm - thumping member 4, the arm - thumping member 4 will swing downward under the action of the spring 17. In this way, the reciprocating swing of the arm - thumping member 4 is realized, and further drives the massage head assembly to perform thumping massage on the human body.

[0029] With this structure of the utility model, through the innovative design of the structure where the cam and the spring cooperate with each other, it can drive the pounding arm to perform high-speed reciprocating swings, thereby increasing the pounding speed. At the same time, by designing the structure of the cam, the amplitude of the swinging of the pounding arm is increased, so that the pounding arm can provide a better pounding and massaging effect, effectively enhancing the user experience; and its overall structure is simpler, facilitating the production and assembly of the massager, and contributing to its large-scale production and promotion; in addition, shock-absorbing springs, buffer mechanisms, etc. are configured to further improve the working stability of the massager, and an adjustable massage head assembly is configured to further enhance its flexibility in use, facilitating the use by users in different positions and of different body types; also, through the innovative mechanism for driving the cam to rotate, the synchronous and asynchronous swings of the two pounding arms can be switched and used, further enriching the pounding and massaging methods.
