[0033] The utility model provides a shoulder and neck massage device, such as Figure 1 As shown, in one embodiment of the utility model, the shoulder and neck massage device specifically includes a bottom shell 10, and the bottom shell 10 is used to accommodate a driving member 20, a gear assembly 30, a first transmission shaft 40, a second transmission shaft 50, a belt assembly 60, a first massage assembly 70 and a second massage assembly 80. The first transmission shaft 40 and the second transmission shaft 50 are arranged in parallel to the bottom shell 10, and the driving member 20 and the gear assembly 30 are arranged between the first transmission shaft 40 and the second transmission shaft 50. Such a layout structure is compact, which can save the internal space of the bottom shell 10 and effectively reduce the volume of the shoulder and neck massage device. The driving member 20 and the gear assembly 30 are connected in transmission, and the power output end of the gear assembly 30 is connected in transmission with the first transmission shaft 40 and the belt assembly 60. The first massage assembly 70 is arranged on the first transmission shaft 40, and the driving member 20 rotates, driving the gear assembly 30 to rotate, thereby driving the first transmission shaft 40 to rotate, and then driving the first massage assembly 70 to do a swinging motion to perform kneading massage on the human neck. The power input end of the belt assembly 60 is coaxially connected to the gear assembly 30, and the power output end is coaxially connected to the second transmission shaft 50. The second massage assembly 80 is arranged on the second transmission shaft 50. The driving member 20 rotates to drive the gear assembly 30 to rotate, thereby driving the belt assembly 60 to work, and then driving the second transmission shaft 50 to rotate, thereby driving the second massage assembly 80 to do reciprocating motion, and providing a percussion massage to the human shoulder. The utility model can provide two functions of kneading massage and percussion massage through a driving member, not only without additionally increasing the specifications and quantity of the driving member, reducing the cost and weight of the product, but also realizing two massage techniques and improving the massage effect. At the same time, the gear assembly 30 and the second transmission shaft 50 are transmitted power through the belt assembly 60. During the operation of the second massage assembly 80, the vibration transmitted to the gear assembly 30 and the driving member 20 through the second transmission shaft 50 and the belt assembly 60 is reduced, and the loosening of the gear assembly 30 and the driving assembly 20 is avoided, thereby ensuring the stability of the structure.

[0034] Reference Figure 4In one embodiment of the utility model, the first massage component 70 is used to provide kneading and pressing for the neck. Specifically, the first massage component 70 includes a bracket 71, a cylindrical cam 72, and an end cover 73. The cylindrical cam 72 is arranged at one end of the second transmission shaft 50 and is rotatably connected to the first transmission shaft 40. A cylindrical convex portion 721 is arranged on a side of the cylindrical cam 72 away from the driving member 20. The bracket 71 is located on a side of the cylindrical cam 72 away from the driving member 20. A kneading massage head 712 is arranged at one end of the bracket 71. A penetrating annular interlocking portion 711 is arranged at the end away from the kneading massage head 712. The annular interlocking portion 711 of the bracket 71 is nested in the cylindrical convex portion 721. A columnar guide column 713 is arranged on the outer wall of the annular interlocking portion hole 711 of the bracket 71. A slide groove (not shown in the figure) is arranged on the bottom shell 10. The length direction of the slide groove is parallel to the first transmission shaft 40. The guide column 713 is inserted into the slide groove and is slidably arranged in the slide groove along the axial direction of the first transmission shaft 40. The driving member 20 works to drive the first transmission shaft 40 to rotate, driving the cylindrical cam 72 to rotate, thereby driving the bracket 71 to move. Since the guide column 713 is slidably arranged in the slide groove along the axial direction of the first transmission shaft 40, the movement trajectory of the bracket 71 is limited, so that the bracket 71 reciprocates along the axial direction of the first transmission shaft 40, thereby driving the kneading massage head 712 to reciprocate and perform kneading massage on the neck. Figure 1 and Figure 3 In one embodiment of the utility model, the second transmission shaft 50 is mounted on the bottom shell 10 through a fixing bracket 51. Specifically, the fixing bracket 51 is provided with a through hole 512, and the second transmission shaft 50 passes through the through hole 512, and a bearing 514 is provided between the through hole 512 and the second transmission shaft 50. The second transmission shaft 50 can rotate relative to the through hole 512, and the fixing bracket 51 is installed to the bottom shell 10 by screwing. Furthermore, a vibration damper 513 is provided between the fixing bracket 51 and the bottom shell 10. The vibration damper 513 is an elastic material, for example, it can be silicone, TPU, and the hardness is 30-70 degrees (Shore hardness A). By providing the vibration damper 513, the vibration transmitted to the bottom shell 10 can be reduced.

[0035] In one embodiment of the utility model, at least one protrusion 511 is respectively provided on both sides of the through hole 512 of the fixing bracket 51, and the protrusion 511 is annular. The bottom shell 10 is provided with a protrusion 11 corresponding to the position and shape of the protrusion 511, and the protrusion 511 is sleeved on the corresponding protrusion 11. The vibration damper 513 is also sleeved on the protrusion 11 and sandwiched between the protrusion 11 and the end surface of the protrusion 511. Optionally, the vibration damper 513 can be an annular ring consistent with the protrusion 511.

[0036] In one embodiment of the utility model, the vibration damping member 513 includes a connecting portion 5131, which is cylindrical and has a central hole 5132 extending therethrough in the axial direction. Both ends of the connecting portion 5131 extend radially to form a first connecting end portion 5133 and a second connecting end portion 5134, respectively. The protrusion 511 is clamped between the first connecting end portion 5133 and the second connecting end portion 5134, and the first connecting end portion 5133 abuts against the bottom shell 10.

[0037] Reference Figure 2 In one embodiment of the utility model, the second massage component 80 includes a crank 81, a bracket 82, a percussion massage head 84, and a mounting shell 85 having a cavity (not shown in the figure) penetrating therethrough. The bracket 82 and the percussion massage head 84 reciprocate along the axis of the cavity of the mounting shell 85. Specifically, one end of the crank 81 is connected to the second transmission shaft 50, and the other end is connected to the bracket 82. The percussion massage head 84 is fixed to the bracket 82 and extends outside the cavity of the mounting shell 85. When the second transmission shaft 50 rotates, the crank 81 is driven to rotate, thereby driving the bracket 82 to reciprocate along the central axis of the cavity of the mounting shell 85. The percussion massage head 84 also reciprocates along the central axis of the cavity of the mounting shell 85 with the movement of the bracket 82, thereby realizing a percussion massage action.

[0038] Furthermore, a vibration damper 513 is provided on the inner wall of the mounting shell 85 , and the vibration damper 513 is sandwiched between the inner wall of the mounting shell 85 and the bracket 82 , so as to reduce the vibration generated during the movement of the bracket 82 and transmitted to the mounting shell 85 , thereby reducing the transmission of vibration to the mounting shell 85 .

[0039] The second massage components 80 can be 2 groups, symmetrically arranged at both ends of the second transmission shaft 50, and the second massage components 80 can also be 3 or more. The percussion massage head 84 can be 1 or more, and is installed on the bracket 82 at the same time, and can be integrally connected or detachably connected, so as to facilitate the replacement of the massage head.

[0040] Furthermore, the outer wall of the mounting shell 85 extends to form at least two protrusions 511, and the protrusions 511 are annular. The bottom shell 10 is provided with protrusions 11 corresponding to the positions of the protrusions 511, and the protrusions 511 are sleeved on the corresponding protrusions 11. After the screw passes through the protrusions 511, the protrusions 511 are locked on the protrusions 11, thereby fixing the protrusions 511 on the protrusions 11. Furthermore, it also includes a vibration damper 513. During installation, the vibration damper 513 is first sleeved on the protrusions 11, and then the protrusions 511 are sleeved on the protrusions 11, and the vibration damper 513 is sandwiched between the protrusions 11 and the protrusions 511. There is a vibration damper 513 between the fixing bracket 51 and the bottom shell 10 to reduce the transmission of the vibration of the second massage component 80 to the bottom shell 10 during the reciprocating motion, so as to prevent the user from feeling the vibration when the body part contacts the bottom shell 10 during the use of the massage device, causing discomfort to the massaged part.

[0041] Furthermore, the second massage component 80 further includes a connecting rod 83, one end of which is rotatably connected to the crank 81, and the other end of which is rotatably connected to the bracket 82. By arranging the connecting rod 83 between the crank 81 and the bracket 82, the problem of the swing angle of the crank 81 being too large, resulting in excessive resistance of the bracket 82 during the movement process, is avoided, the power loss during the transmission process is reduced, and the transmission efficiency is improved. Specifically, the connecting rod is a Z-shaped structure.

[0042] Reference Figure 1 In one embodiment of the utility model, the driving member 20 includes a motor 21 and a driving gear 22 connected to the motor 21. The gear assembly 30 includes a first gear module 31 and a second gear module 32, and the first gear module 31 and the second gear module 32 are both meshed with the driving gear 22. The belt assembly 60 includes a first pulley 61, a second pulley 62, and a belt 63, and the two ends of the belt 63 are respectively sleeved on the first pulley 61 and the second pulley 62. The motor 21 is started, driving the driving gear 22 to rotate, and then transmitting the power to the first transmission shaft 40 through the first gear module 31, and transmitting the power to the second transmission shaft 50 through the second gear module 32 and the belt assembly 60. The power of the motor 21 is transmitted to the second massage assembly 80 through the belt assembly 60. Compared with relying entirely on gear transmission, the vibration reduction effect of the belt assembly is better.

[0043] In some embodiments, the first gear module 31 and the second gear module 32 are both provided with one-way bearings. When the motor 21 rotates, one of the first gear module 31 and the second gear module 32 rotates, and the other does not rotate, so that only one of the first transmission shaft 40 and the second transmission shaft 50 rotates at a time. Therefore, one of the first massage component 70 and the second massage component 80 is in a working state, and the other is in a standby state. The massage device only provides one massage technique at a time.

[0044] In some embodiments, a one-way bearing may be provided in one of the first gear module 31 and the second gear module 32, while the other one may not be provided with a one-way bearing. For example, a one-way bearing is provided in the second gear module 32, and when the motor 21 is in forward transmission, both the first gear module 31 and the second gear module 32 rotate, driving the first massage component 70 and the second massage component 80 to work simultaneously, and the massage device provides two massage techniques of tapping and kneading at the same time. When the motor 21 is reversed, the first gear module 31 rotates, and the second gear module 32 stops rotating, and then the first massage component 70 works, and the second massage component 80 stops working, and the massage device only provides kneading massage. Therefore, the massage device can provide a composite massage technique of kneading the neck and patting the shoulders at the same time, with a large massage area, and can also provide a single kneading massage or a single tapping technique according to user needs, and the product functions are more diversified and the massage experience is good.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
