DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

As shown in FIGS. 1 to 7 , a massage device of the present invention includes a massage housing 1 , a drive motor 2 , a transmission assembly 3 , a rotating assembly 4 and a massage head 5 .

As shown in FIG. 4 and FIG. 5 , the massage housing 1 includes an upper housing 11 and a lower housing 12 which are covered to form a housing space S, and the driving motor 2 and the transmission assembly 3 are arranged in the housing space S.

In this embodiment, there are two massage heads 5 symmetrically arranged on the left and right (see Figures 2 and 3), and the rotating components 4 are arranged in two groups corresponding to the massage heads 5; the driving motor 2 is installed in the middle of the lower shell 12, and the transmission component 3 takes two groups of gear groups 31 distributed on the left and right as an example. The gear group 31 can be an existing reduction gear group. The input sides of the two gear groups 31 are simultaneously engaged with the worm 21 of the output shaft of the central driving motor 2, and the output sides of the two gear groups 31 away from the driving motor 2 are respectively engaged with a group of rotating components 4, and the rotating components 4 are connected to the massage heads 5, and the massage heads 5 are located outside the upper shell 11.

The rotating assembly 4 includes a rotating wheel 41, a rotating rod 42 and a limiting member 43;

The rotating wheel 41 can be a rotating gear and can be horizontally rotatably engaged with the output side of the gear set 31. Specifically, a bearing 6 can be sleeved on the lower part of the rotating wheel 41 so that the rotating wheel 41 can be rotatably installed on the lower shell 12. The upper top surface of the rotating wheel 41 is provided with an arc-shaped concave surface 411, and an eccentric inclined hole 412 is provided in the arc-shaped concave surface 411. The teeth 413 of the rotating gear are circumferentially arranged on the side between the upper and lower parts.

Referring to Figure 6, the rotating rod 42 includes an upper connecting rod portion 421 and a lower ball head portion 422 connected to each other. The connecting rod portion 421 is upwardly connected to the massage head 5. Specifically, the connecting rod portion 421 can be inserted and locked in the mounting hole 50 at the bottom of the massage head 5; the ball head portion 422 is downwardly embedded in the arc-shaped concave surface 411 that fits the top surface of the rotating wheel 41, and at the same time, a guide rod 423 inserted and matched in the eccentric inclined hole 412 is provided on the lower side of the ball head portion 422. The guide rod 423 is centrally arranged directly below the ball head portion 422 and obliquely inserted in the eccentric inclined hole 412 of the arc-shaped concave surface 411. At the same time, the guide rod 423 can be arranged colinearly with the connecting rod portion 421. Therefore, when the rotating wheel 41 rotates horizontally, the eccentric inclined hole 412 in the arc-shaped concave surface 411 drives the inclined guide rod 423 below the ball head 422 of the rotating rod 42 to make a circular motion, and then drives the inclined connecting rod part 421 to make a circular motion, thereby realizing the circular swinging motion of the massage head 5.

By arranging the ball head 422 to cooperate with the arc-shaped concave surface 411, the contact area between the two can be increased, the pressure can be effectively reduced, and the wear is reduced, that is, the rotating rod 42 is made more wear-resistant.

Referring to FIG. 7 , two limit rods 424 are respectively protruded from the two horizontal sides of the ball head 422. The limit rods 424 and the guide rods 423 are perpendicularly arranged to each other. Meanwhile, the limit rods 424 are limited to the limit members 43 arranged above the rotating wheel 41, so as to limit the rotation of the ball head 422 and prevent the rotating rod 42 from being separated from the rotating wheel 41 during the movement.

The position-limiting member 43 of this embodiment is an independent structure to facilitate manufacturing, and the position-limiting member 43 can be made of wear-resistant material to improve the wear-resistant effect. Specifically, the upper shell 11 is provided with clearance holes 111 corresponding to the two rotating rods 42, and the ball head 422 is installed at the clearance holes 111. The position-limiting member 43 is locked and installed above the clearance holes 111 of the upper shell 11 and the ball head 422 to limit the ball head 422. Of course, the position-limiting member 43 can also be integrally formed at the clearance holes 111 of the upper shell 11.

The limiting member 43 includes a spherical cover 431 and two limiting grooves 432. The spherical cover 431 is arranged on the outer periphery of the top of the ball head 422, and a movable hole 4311 is arranged on the top of the spherical cover 431 for the connecting rod 421 to extend out of the shell space S for movement. The two limiting grooves 432 are respectively formed on both sides of the spherical cover 431. When the ball head 422 rotates, the two limiting rods 424 swing up and down and rotate in the limiting grooves 432, and are limited upward by the limiting grooves 432.

The top surface of the limiting rod portion 424 may be configured as an arc-shaped surface, which may facilitate the movement of the limiting rod portion 424 in the limiting groove 432 .

The top of the guide rod 423 of this embodiment is inserted and fixed in the groove 4221 of the ball head 422 to facilitate production and manufacturing. For example, the guide rod 423 can be made of a hard metal material with high strength to improve product durability. The ball head 422 is then molded by overmolding. The ball head 422, the connecting rod 421 and the limiting rod 424 can all be made of wear-resistant materials.

3 and 4 , the massage head 5 includes a silicone upper cover 51, a hard massage head 52 and a massage head lower cover 53. The silicone upper cover 51 and the massage head lower cover 53 cover the hard massage head 52. The silicone upper cover 51 is arranged corresponding to the massage convex part of the hard massage head 52. The silicone upper cover 51 is used to directly contact the user and can buffer the massage of the hard massage head 52.

The massage head 5 of the present embodiment has an appearance of three connected spheres. Specifically, the massage head 5 of the present embodiment is symmetrically arranged, and the appearance of the massage head 5 includes a first sphere 5A, a second sphere 5B and a third sphere 5C which are connected in sequence front to back, and the three spheres can be connected in an arc shape, and the arcs of the two massage heads 5 are relatively expanded outward; the connecting rod portion 421 of the above-mentioned rotating rod 42 is inserted into the mounting hole 50 set at the bottom of the middle second sphere 5B, so that when the rotating component 4 drives the massage head 5 to rotate, the first sphere 5A, the second sphere 5B and the third sphere 5C of the massage head 5 can respectively perform circular motion to achieve a rotating kneading massage effect.

The working principle of the utility model can be as follows:

The driving motor 2 in the shell space S outputs power to rotate the worm 21 and then synchronously link the gears of the left and right gear sets 31 of the transmission assembly 3 to rotate, thereby linking the rotating wheels 41 of the left and right rotating assemblies 4 to rotate horizontally, and the eccentric inclined hole 412 in the arc-shaped concave surface 411 of the rotating wheel 41 rotates eccentrically, driving the guide rod 423 of the rotating rod 42 to make an eccentric rotation, thereby linking the connecting rod part 421 and the various balls of the massage head 5 to perform circular motion to achieve a massage function.

The massage housing 1 of the massage device can be covered with a cloth cover for protection, and is mainly suitable for massaging the shoulders and neck of the user.

The utility model has at least the following advantages:

By providing the rotating rod 42 with a ball head 422 that cooperates with the arcuate concave surface 411 of the rotating wheel 41, and the ball head 422 is made of wear-resistant material, both can be made more wear-resistant, the service life of the product is increased, and a good massage effect is guaranteed.

The guide rod 423 made of a metal hard material has high strength, can improve the swing effect, is not easy to be damaged, and can increase the service life.

Providing an independent limiter 43 can facilitate the production of components, and can be made of wear-resistant material alone to avoid rapid wear and damage by the limiter rod 424 of the rotating rod 42. At the same time, the upper shell 11 and the lower shell 12 can be made of other materials to reduce product costs.
