[0017] The following further details the specific embodiments of the present utility model. It should be understood that the description of the embodiments of the present utility model herein does not limit the protection scope of the present utility model.

[0018] As Figures 1 to 4 shown, it is a schematic structural view of the massage mechanism for back massage provided by the present utility model. The massage mechanism for back massage includes a base 10, a kneading assembly 20 disposed on the top of the base 10, and a pounding assembly 30 disposed on one side of the kneading assembly 20. The massage mechanism for back massage further includes some other functional modules, such as a controller disposed on the base 10 for controlling the kneading assembly 20 and the pounding assembly 30, and a distribution box, etc., which should be well-known technologies to those skilled in the art and will not be elaborated in detail herein one by one.

[0019] The base 10 is a rectangular plate-like structure to serve as a base for carrying the above-mentioned various functional modules, and should also be connected with existing technologies such as a circuit system and a control unit, which will not be elaborated in detail herein one by one. A plurality of grids are respectively disposed on the main body planes on both sides of the base 10 to increase the structural strength of the base 10.

[0020] The kneading assembly 20 includes a kneading driving rod 21 horizontally disposed on the base 10, a first driving motor 22 disposed on the base 10 and used for driving the kneading driving rod 21 to rotate, two first eccentric wheels 23 symmetrically sleeved on the kneading driving rod 21, two annular mounting bodies 24 respectively sleeved on each of the first eccentric wheels 23, two mounting rods 25 respectively rotatably disposed on each of the annular mounting bodies 24, and two groups of massage wheels 26 respectively disposed at both ends of each of the mounting rods 25.

[0021] The kneading driving rod 21 is rotatably mounted on the base 10 through a bearing seat. The first driving motor 22 is disposed in the middle of the kneading driving rod 21, and the first driving motor 22 is rotationally connected with the kneading driving rod 21 through a gear set for driving the kneading driving rod 21 to rotate around an axis. The first eccentric wheel 23 is fixedly disposed on the kneading driving rod 21 and is used to cooperate with the annular mounting body 24 and the following pounding connecting rod to swing the annular mounting body 24 along the axial direction of the kneading driving rod 21 to achieve a kneading effect.

[0022] The annular mounting body 24 is rotatably connected to the first eccentric wheel 23. The annular mounting body 24 includes an annular main body 241, a mounting rod mounting portion 242 provided on the outer side of the annular main body 241, a connecting ball mounting portion 243 provided on the outer side of the annular main body 241, and a push block 244 provided on the annular mounting body 24. A guide rail 245 is provided on the inner wall of the annular mounting body 24. A bearing 246 is fixedly sleeved on the first eccentric wheel 23, and the bearing 246 is clamped in the guide rail 245, so that the farthest end of the eccentric wheel 23 away from the center of the circle is always located in the guide rail 245, and drives the annular mounting body 24 to swing during eccentric rotation. Specifically, the annular mounting body 24 swings reciprocally along the axial direction of the kneading driving rod 21 with the center of the first eccentric wheel 23 as the rotation point.

[0023] The annular main body 241 is sleeved outside the first eccentric wheel 23. The mounting rod mounting portion 242 is used to provide a mounting position for the mounting rod 25.

[0024] The connecting ball mounting portion 243 includes two mutually buckled positioning plates 2431, and hemispherical mounting grooves 2432 respectively provided on the opposite sides of the two positioning plates 2431. A through hole 2433 for the following hammering connecting rod to pass through is provided on one side of the hemispherical mounting groove 2432. The connecting ball 34 is rotatably inserted into the spherical cavity formed by the two hemispherical mounting grooves 2432 to ensure the stable connection between the following hammering connecting rod 35 and the annular mounting body 24 when the annular mounting body 24 swings.

[0025] The push block 244 is located between the mounting rod mounting portion 242 and the connecting ball mounting portion 243. The push block 244 abuts against the bottom of one end of the mounting rod 25. When the annular mounting body 24 rotates in one direction, the body block 244 will push one end of the mounting rod 25 to rise, and further make the other end of the mounting rod 25 away from the human body, generating the distance required for knocking the human body.

[0026] The mounting rod 25 is rotatably connected to the annular mounting body 24 through a pin 251. A massage wheel 26 is provided at each end of each mounting rod 25. The two massage wheels 26 and the pin are distributed in a triangle. The sizes of the two massage wheels 26 on each mounting rod 25 are different. The size of one massage wheel 26 away from the push block 244 is larger than the other. Since the side away from the push block 244 massages the upper back and the part near the shoulder of the user, which is the main massage area, the larger massage wheel 26 can provide a larger massage range to ensure the massage effect.

[0027] A tension spring 27 is respectively arranged between each of the mounting rods 25 and the first eccentric wheel 23, so as to buffer the knocking and stabilize the mounting rod 25 when the mounting rod 25 knocks.

[0028] The hammering assembly 30 includes a hammering driving rod 31 horizontally arranged on the base 10, a second driving motor 32 arranged at the bottom of the base 10 and used for driving the hammering driving rod 31, two collar rings 33 symmetrically sleeved on the hammering driving rod 31, second eccentric wheels 36 respectively arranged between each of the collar rings 33 and the hammering driving rod 31, two hammering connecting rods 34 horizontally hinged on each of the collar rings 32 respectively, and connecting balls 35 respectively arranged at the ends of each of the hammering connecting rods 33.

[0029] It should be noted that the second eccentric wheel 36 makes the collar ring 33 eccentrically arranged with the hammering driving rod 31. The 36 is only at Figure 4 the marked position.

[0030] The hammering driving rod 31 is horizontally arranged on the base 10 through a bearing seat. The second driving motor 32 and the hammering driving rod 31 are connected by a belt pulley. During use, the second eccentric wheel swings along the axial direction of the hammering driving rod 31, so as to pull the hammering connecting rod 34. The hammering connecting rod 34 pulls the annular mounting body 24 to rotate, and further makes the push block 244 located on the annular mounting body 24 push the mounting rod 25 to reciprocate, so as to continuously knock the back. The connecting ball 35 ensures that when the annular main body 241 swings, the hammering connecting rod 34 is rotatably connected with the annular main body 241 to ensure the firmness of the connection.

[0031] Two limiting pieces 331 are respectively arranged at intervals along the circumferential direction on each of the collar rings 33. One end of the hammering connecting rod 34 is clamped between the two limiting pieces 331, and the hammering connecting rod 34 is respectively hinged with the two limiting pieces 331, so that it can only rotate in one plane.

[0032] Compared with the prior art, the massage mechanism for back massage provided by the utility model drives a push block 244 to be arranged on the annular mounting body 24, and a hammering connecting rod 33 is hinged on the annular mounting body 24. The hammering connecting rod 33 is controlled to drive the annular mounting body 24 to rotate, so that the push block 244 pushes the mounting rod 25 to rotate, and further enables the massage wheel 26 at one end of the mounting rod 25 to leave the human body. After that, the hammering connecting rod 33 swings with the collar 33 and resets, and pulls the annular mounting body 24 to rotate back. The massage wheel 26 also returns with the mounting rod 25 and generates a knock, that is, the back of the user is struck. Since the massage method of striking is added and combined with the original rubbing method, the user can obtain a comfortable massage experience.

[0033] The above are only the preferred embodiments of the present utility model and are not used to limit the protection scope of the present utility model. Any modification, equivalent replacement or improvement within the spirit of the present utility model is covered within the scope of the claims of the present utility model.
