Embodiment 1

This embodiment provides a massage unit 010. Please refer to FIG. 1. The massage unit 010 includes a first cross plate 100, a second cross plate 200 and a driving part 300.

Referring to Figures 1, 3 and 4, the first intersection plate 100 includes a first side bar 110 and a first intersection portion located on one side of the first side bar 110. The first intersection portion includes a plurality of first intersecting plates arranged in parallel and spaced apart. Side rod 131, the first side rod 131 and the first side rod 110 are arranged vertically. The second intersection plate 200 includes a second side rod 210 and a second intersection portion located on one side of the second side rod 210. The second intersection portion includes a plurality of second side rods 231 arranged in parallel and spaced apart. The second side rods 231 are connected to the second side rod 231. The two side poles 210 are arranged vertically, with the first intersection facing the second side pole 210 and the second intersection facing the first side pole 110. The first side poles 131 and the second side poles 231 are arranged in a staggered manner. The staggered arrangement of the first cross plate 100 and the second cross plate 200 allows the first cross plate 100 and the second cross plate 200 to be driven respectively when a person lies on the first cross plate 100 and the second cross plate 200 to achieve alignment. Massage for people. The massage interval between the first cross plate 100 and the second cross plate 200 can also be adjusted by adjusting the distance between the first side pole 110 and the second side plate to achieve massage for people of different body types.

Among them, the first cross plate 100 and the second cross plate 200 of some special shapes can be provided with ground side rods and side rods that are not perpendicular, but have a certain angle, to achieve different massage effects.

The first side rod 131 has a width parallel to the axial direction of the first side rod 110 , and the gap between two adjacent second side rods 231 is 1.8 times the width of the first side rod 131 . When the first side rod 131 is inserted between two adjacent second side rods 231, it does not contact the second side rods 231 on both sides, which not only facilitates the operation of the first cross plate 100 and the second cross plate 200, but also avoids the first cross plate 100 and the second cross plate 200. The collision between the cross plate 100 and the second cross plate 200 during operation can also increase the pressure exerted on people in the massage area and improve the massage effect.

Similarly, the second side rod 231 has a width parallel to the axial direction of the second side rod 210, and the gap between two adjacent first side rods 131 is 1.8 times the width of the second side rod 231, so that the second side rod 231 has a width parallel to the axial direction of the second side rod 210. When the side rod 231 is inserted between two adjacent first side rods 131, it does not contact the first side rods 131 on both sides, which not only facilitates the operation of the first cross plate 100 and the second cross plate 200, but also prevents the first cross plate 100 from being It will not collide with the second cross plate 200 when working, and can increase the pressure exerted on the person by the massage area and improve the massage effect.

Please refer to Figure 2. The first side rod 131 includes a metal core 133 and a rubber skin 135. The thickness of the rubber skin 135 is greater than 3 mm. The arrangement of the rubber skin 135 can not only provide an attachment base for massage essential oils or other massage potions, but also improve the overall comfort of the massage.

The first intersection portion has a first surface, and the first side rod 131 is also provided with rubber protrusions (not shown in the figure) on the first surface. The rubber protrusions can be used to massage the point portion. Similarly, rubber bumps can also be provided at corresponding positions of the second side rod 231 .

The driving part 300 is used to drive the first cross plate 100 to perform a first movement. The displacement of the first movement in the axial direction of the first side rod 110 is zero. The driving part 300 is also used to drive the second cross plate 200 to perform a second movement. , the displacement of the second movement in the axial direction of the second side rod 210 is zero. That is, the driving part 300 does not drive the first cross plate 100 to move in the axial direction of the first side bar 110 , nor does it drive the second cross plate 200 to move in the axial direction of the second side bar 210 .

In this embodiment, the driving part 300 includes a driving member 310, a crankshaft 330, a first connecting rod 350 and a second connecting rod 370. The driving crankshaft 330 simultaneously drives the first cross plate 100 and the second cross plate 200 to move, so that the first cross plate 100 and the second cross plate 200 move. The cross plate 100 and the second cross plate 200 perform cyclic non-circular motion.

The crankshaft 330 includes a main journal 331 connected to the output end of the driving member 310, and a first crank 333 and a second crank 335 that are symmetrical with respect to the main journal 331. The first crank 333 and the second crank 335 are respectively located on the main journal. 331 on both sides. One end of the first connecting rod 350 is hinged with the first side rod 110 , and the other end is hinged with the connecting rod neck of the first crank 333 . One end of the second connecting rod 370 is hinged with the second side rod 210 , and the other end is hinged with the second crank 335 The connecting rod neck is hinged.

When the driving member 310 drives the crankshaft 330 to rotate with the main journal 331 as the axis, the first crankshaft 333 and the second crankshaft 335 also rotate with the main journal 331 as the axis, and the connecting rod neck of the first crankshaft 333 and the second crankshaft 333 also rotate with the main journal 331 as the axis. The connecting rod necks of the second crankshaft 335 are arranged on both sides of the main journal 331, so that the connecting rod necks of the first crankshaft 333 and the connecting rod necks of the second crankshaft 335 have staggered motion routes.

Through the massage unit 010 provided by the present invention, a single-sided comprehensive massage can be performed on the person lying on the first cross plate 100 and the second cross plate 200, and the first movement of the first cross plate 100 and the second cross plate 200 The second movement is a staggered movement route, so that when the massage unit 010 is actually working, people will periodically turn over slightly, and the people and the fitting surfaces of the first cross plate 100 and the second cross plate 200 will periodically move During this process, the reaction force exerted by the massage unit 010 on the person (the reaction force relative to the person's gravity) will act on different human body areas, making the massage more comprehensive and the effect more significant. The massage unit 010 can not only be used for massage, but also suitable for the field of scrubbing to realize mechanized scrubbing.
