Description

Technical Field

[0001] The utility model relates to the technical field of massagers, in particular to a movement of a neck massager. Background Art

[0002] In the prior art, the shoulder and neck massager includes a kneading component and a massaging component. The kneading component realizes the kneading function by swinging the kneading arm, and the massaging component realizes pinching and massaging by swinging the massaging arm. The transmission method usually adopts a double-headed motor, which is then transmitted through a worm gear, and then the driven gear drives the cooperation of the bevel eccentric wheel and the eccentric piece, so as to realize the kneading of the kneading arm and the massaging of the massaging arm. However, the worm gear cannot directly engage with the driven gear, so it is necessary to set a transmission gear above or below the worm gear, and further drive the driven gear to rotate through the transmission gear. Therefore, more gear sets are required, and the assembly is more complicated. Utility Model Content

[0003] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a movement of a neck massager, which has a simple internal structure and is convenient to install.

[0004] The utility model discloses a movement of a neck massager, comprising a shell, on which a kneading arm, a massage arm and a driving mechanism for driving the kneading arm and the massage arm to work are arranged, the driving mechanism comprising a driving motor arranged transversely on the shell, a worm gear, a first eccentric structure for driving the massage arm to massage, and a second eccentric structure for driving the kneading arm to knead, the first eccentric structure comprising an eccentric piece arranged on the worm gear, a transmission arm sleeved on the eccentric piece, an end of the transmission arm away from the eccentric piece being hingedly arranged on the massage arm, and characterized in that the second eccentric structure comprises an inclined column arranged on the worm gear and rotating synchronously with the worm gear, the kneading arm is arranged on the inclined column, a driving member for driving the kneading arm to knead is arranged on the inclined column, a guide groove arranged along the vertical direction is further arranged on the shell, and a guide member for guiding and sliding in the guide groove is arranged on the kneading arm.

[0005] By adopting the above technical solution, the driving motor drives the worm wheel to rotate, and the worm wheel drives the inclined column to rotate. Furthermore, the circumferential rotation of the kneading arm can be limited by the driving of the driving member and the guiding of the guide structure, thereby achieving the kneading effect. At the same time, when the worm wheel rotates, the eccentric member can be driven to rotate, and the rotation of the eccentric member can drive the transmission arm to extend and retract, and the extension and retraction of the transmission arm can pull or push the massage arm to perform massage. The direct drive by the worm wheel can simplify the internal structure, and the torque can be increased and the rotation speed can be reduced by increasing the number of teeth of the worm wheel.

[0006] The utility model is further configured as follows: the driving member is a connecting rod arranged on the inclined column, the connecting rod and the inclined column are coaxial, one end of the connecting rod is inserted on the inclined column, and the other end is inserted on the kneading arm, a hemispherical surface is also provided at the bottom of the kneading arm, a spherical cover matching the hemispherical surface is provided on the shell, the spherical cover is provided on the hemispherical surface to form a disengagement limit, and an avoidance hole is also provided on the shell for the kneading arm to pass through and swing.

[0007] By adopting the above technical solution, the connecting rod rotates synchronously with the tilting column during use. At this time, the kneading arm can be driven to knead by the rotation of the connecting rod, and the kneading arm can be prevented from being separated from the connecting rod by the cooperation of the hemispherical surface and the spherical cover, making it more stable when in use.

[0008] The utility model is further configured as follows: the guide piece is arranged on the hemispherical surface, and the guide groove is arranged on the shell body at a position corresponding to the spherical cover.

[0009] By adopting the above technical solution, the structural layout is more reasonable and the internal structure can be further simplified.

[0010] A further configuration of the utility model is that a plurality of first reinforcing ribs are arranged on the outer wall of the shell corresponding to the spherical cover.

[0011] By adopting the above technical solution, the structural strength of the spherical cover can be enhanced to prevent it from being damaged.

[0012] A further configuration of the utility model is that a second reinforcing rib is provided at a hinged position of the massage arm corresponding to the transmission arm.

[0013] The above technical solution can prevent the corresponding hinged joint of the massage arm from breaking. BRIEF DESCRIPTION OF THE DRAWINGS
