[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] like Figures 1 to 4 As shown, the utility model is an arm massage device on a massage chair side panel 1, the massage chair side panel 1 has a massage groove 10 for placing the arm, wherein the arm massage device includes: a shell 2, which is arranged in the massage chair side panel 1, and an installation cavity 20 is formed inside the shell 2; a driving member 3 accommodated in the shell 2, and an output shaft 30 is provided on the driving member 3, and the end of the output shaft 30 passes through the shell 2 and is exposed outside the shell 2; a massage block 4 and a kneading plate 5, which are arranged outside the shell 2 and move at the bottom of the massage groove 10, the massage block 4 is connected to the output shaft 30, and the massage The center line of the block 4 is arranged parallel to the axis line of the output shaft 30, and a first massage convex point 40 is formed on the top wall of the massage block 4; the kneading plate 5 is movably connected to the shell 2, and a traction plate 6 is movably hinged between the kneading plate 5 and the massage block 4, and at least one second massage convex point 50 is formed on the top wall of the kneading plate 5; when the driving member 3 drives the massage block 4 to rotate eccentrically, the first massage convex point 40 is used to perform a circular massage on the arm, so that the traction plate 6 guides the kneading plate 5 to move back and forth in a straight line, so that the second massage convex point 50 can synchronously perform linear kneading on the palm.

[0032] This embodiment is mainly for achieving all-round massage of the arm, specifically, Figures 1 to 3 As shown, when the user places the arm in the massage groove 10 of the side panel 1 of the massage chair and starts the device, the driving member 3 starts to operate and drives the output shaft 30 to rotate. Since the rotation center of the massage block 4 is arranged parallel to the axis of the output shaft 30, when the massage block 4 rotates eccentrically, the first massage protrusion 40 on the massage block 4 will perform continuous circular massage on the surface of the arm along the rotation trajectory, thereby simulating the kneading action of the human hand; at the same time, the rotation of the massage block 4 transmits power to the kneading plate 5 through the traction plate 6 hinged thereon, so that the kneading plate 5 moves back and forth in a straight line along the trajectory in the length direction of the shell 2 at the bottom of the massage groove 10, and the second massage protrusion 50 on the kneading plate 5 performs linear kneading massage on the palm along its linear motion, thereby simulating the squeezing and sliding action of the fingers. Since the rotation of the massage block 4 and the linear reciprocating motion of the kneading plate 5 are carried out synchronously, the user's arm can feel the linear kneading massage at the same time as the palm of the hand receives the rotation massage. The arm massage device combines the massage methods of rotation and linear motion, can cover different parts of the arm, provide a comprehensive massage experience, increase the layering and variability of the massage, and thus improve the user's comfort and satisfaction.

[0033] Preferably, if Figure 4As shown, the kneading plate 5 in this embodiment is also equipped with an airbag (not shown in the figure). When the airbag is inflated, it can wrap the wrist and palm and perform kneading and massaging movements on them simultaneously. Accompanied by the kneading and massaging of the palm by the above-mentioned second massage protrusions 50, the comfort brought to the user when the massage device massages various parts of the arm is further enhanced.

[0034] The output shaft 30 is provided with a connecting block 31 , and a fixed shaft 310 is mounted on the connecting block 31 . The axis of the fixed shaft 310 is arranged parallel to the axis of the output shaft 30 , and the massage block 4 is connected to the fixed shaft 310 .

[0035] like Figure 2 As shown, the connection between the output shaft 30 and the connecting block 31 is located at the bottom of the connecting block 31, and the fixed shaft 310 is located at the top of the connecting block 31, and the connection and the fixed shaft 310 are distributed at both ends of the connecting block 31. In addition, the axis of the fixed shaft 310 is arranged parallel to the axis of the output shaft 30, which ensures that the massage block 4 can maintain a stable motion trajectory during rotation. At the same time, it also provides a guarantee for the stability of the eccentric rotation of the massage block 4 when driving the above-mentioned kneading plate 5 to realize a linear massage trajectory relative to the shell 2.

[0036] The bottom wall of the kneading plate 5 is detachably connected to a sliding block 51 . The top wall of the housing 2 is formed with a guide groove 21 along its length direction. The sliding block 51 is movably disposed in the guide groove 21 .

[0037] like Figures 1 to 3 As shown, it is worth noting that the kneading plate 5 can be connected to the sliding block 51 via screws, bolts, or other connecting components to achieve synchronous movement of the two, ensuring that the comfort of the second massage protrusions 50 performing linear kneading of the palm is not affected. Because the housing 2 is located at the bottom of the massage groove 10, the guiding and limiting effects of the guide groove 21 further enhance the smoothness and stability of the linear kneading massage action of the second massage protrusions 50.

[0038] An extension plate 52 is installed at the bottom of the sliding block 51 , and a traction column 520 is provided on the extension plate 52 . One end of the traction plate 6 is movably hinged to the traction column 520 , and the other end is movably hinged to the fixed shaft 310 .

[0039] like Figures 2 to 3As shown, when the massage block 4 performs eccentric rotational motion when the driving member 3 is turned on, the fixed shaft 310 also rotates accordingly. Since the two ends of the traction plate 6 are hinged to the fixed shaft 310 and the traction column 520 respectively, the traction plate 6 will tilt or reset according to the position change of the fixed shaft 310. Specifically, when the traction plate 6 tilts, the traction column 520 will move along a certain trajectory, thereby driving the sliding block 51 to perform a linear reciprocating motion in the guide groove 21, so that the second massage protrusion 50 will perform a linear kneading massage on the palm during its reciprocating motion.

[0040] Preferably, if Figure 2 As shown, in this embodiment, through holes 60 are provided at both ends of the traction plate 6, and bearings 61 are installed on the traction column 520 and the fixed shaft 310. The outer ring of the bearing 61 is interference fit with the inner wall of the through hole 60, which provides a guarantee for the smoothness of the traction plate 6 when it rotates and tilts according to the position change of the fixed shaft 310, thereby improving the stability of the sliding block 51 when driving the second massage protrusion 50 to perform linear kneading massage, and effectively avoiding the traction plate 6 from getting stuck and affecting the user's palm massage experience.

[0041] A locking column 210 is provided in the guide groove 21, and a positioning sleeve 211 and a locking disk 212 are installed on the locking column 210 in sequence from bottom to top. A stepped locking groove 510 is opened in the sliding block 51. The locking column 210 and the positioning sleeve 211 extend into the locking groove 510, and are movably engaged through the locking disk 212 and pressed against the inner wall of the locking groove 510.

[0042] like Figures 2 to 4 As shown, as the traction plate 6 tilts or resets, the sliding block 51 can perform linear reciprocating motion along the trajectory of the guide groove 21. At the same time, the active engagement of the locking column 210 and the positioning sleeve 211 within the locking groove 510 ensures the stability of the sliding block 51 during linear motion, and the tightening action of the locking disk 212 effectively prevents the sliding block 51 from shaking or deviating during motion. It should be noted that the locking column 210 and positioning sleeve 211 in this embodiment are provided at four locations. Of course, the stability of the triangle can also be utilized to provide three locations of the above structure to ensure the smoothness and stability of the movement of the sliding block 51. In addition, the positioning sleeve 211 and the locking disk 212 are both detachably mounted on the locking column 210, providing great convenience for subsequent maintenance and replacement.

[0043] The bottom wall of the kneading plate 5 is further provided with a limiting post 53 . A limiting groove 213 is provided in the guide groove 21 . The limiting post 53 passes through the sliding block 51 and is movably engaged in the limiting groove 213 .

[0044] Preferably, if Figure 4As shown, when the sliding block 51 moves back and forth in a straight line along the guide groove 21, since the kneading plate 5 is connected to the sliding block 51, the limiting post 53 at the bottom of the kneading plate 5 passes through the sliding block 51 and extends into the limiting groove 213, ensuring that the kneading plate 5 does not deviate from the predetermined trajectory during the straight reciprocating motion, thereby maintaining the stability and reliability of the kneading action.

[0045] The sliding block 51 is provided with a first annular clearance hole 511 and a second annular clearance hole 512 which are interconnected. The top end of the output shaft 30, the connecting block 31 and the traction plate 6 are all located in the first annular clearance hole 511. The second annular clearance hole 512 allows the massage block 4 to pass through and extend into the massage groove 10.

[0046] like Figures 1 to 3 As shown, in this embodiment, the top end of the output shaft 30, the connecting block 31 and the traction plate 6 are all located in the first annular clearance hole 511, ensuring that these components have sufficient space for unimpeded movement during rotation, while ensuring that their positions are relatively stable; and the second annular clearance hole 512 is designed to allow the massage block 4 to pass through the sliding block 51 and extend into the massage groove 10, so as to ensure that the massage block 4 contacts the user's arm and achieves the desired massage operation.

[0047] It should be noted that the driving member 3 in this embodiment can be replaced by other driving devices such as a stepping motor, a servo motor, etc.

[0048] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).
