In FIG. 6A-6C are views illustrating an example of adjusting the height of the first driving rocker while the first driving cam is rotating.

Below with reference to FIG. 6A-6C describe the process for adjusting the height of the first drive rocker 130 using the first drive cam 110.

First, as illustrated in FIG. 6A, when the first drive cam PO is at the same location and the drive swash plate 10 rotates in the same direction, the cam 110 also rotates.

Then, as illustrated in FIG. 6B, when the first driving cam 110 rotates in one direction, the height of said cam lobe 112 may decrease. Because the cam 110 is asymmetrical in shape with respect to the first rotary shaft 30, the center of the cam 110 is lowered depending on the height 30H of the shaft 30. Accordingly, the height of the first driving rocker 130 is also reduced, and the height of the first driving massage roller 140 is reduced.

Further, as illustrated in FIG. 6C, when the first drive cam 110 continues to rotate in the same direction, the height of said cam lobe 112 may increase. In this case, depending on the height 30H of the first rotary shaft 30, the center of the cam 110 may rise. Accordingly, the height of the first driving rocker 130 also increases, and the height of the first driving massage roller 140 increases.

From the above description, it can be seen that the position of the first drive cam lobe 112 is related to the height of the first drive rocker cam 130. In addition, one skilled in the art can easily apply the above described process for adjusting the height of the rocker 130 using the first drive cam 110 to the first driven cam. block 300, the second master block 500 and the second slave block 700.

The massage module 1 for a massage device according to an embodiment of the present invention is configured to switch between the first operation mode (AM, smooth movement mode) and the second operation mode (ZM, zigzag movement mode) in accordance with the direction of rotation of the drive swivel washer 10.

Accordingly, since the massage unit 1 for the massage device according to the embodiment of the present invention can massage the human body in multiple modes, it is advantageous that the effect of acupuncture can be improved with various stimulating effects. In addition, since the massage unit 1 for the massage device according to the embodiment of the present invention is implemented in a structure that can achieve mode switching by a relatively simple operation of changing the rotation direction of the drive swivel 10, mode switching can be simplified.

Below with reference to FIG. 7A and 7B describe the operating state in the first AM operation mode according to the embodiment of the present invention. It should be understood that the notation for the direction of rotation shown in FIG. 7A and 7B does not mean that the first mode of operation is provided only in a certain direction of rotation, but is shown to distinguish the direction of rotation in the first mode from the direction of rotation in the second mode.

According to an embodiment, in the first mode of operation AM, the first driving massage roller 140 and the first driven massage roller 340 can operate in the same direction. As an example, in the first mode AM of operation, the first master massage roller 140 and the first driven massage roller 340 may rotate at the same height. As another example, in the first mode AM of operation, the first master massage roller 140 and the first driven massage roller 340 may be jointly raised or lowered. To this end, the protrusion 112 of the first driving cam and the protrusion 312 of the first driven cam can rotate at the same height (phase).

As another example, the first master massage roller 140, the first driven massage roller 340, the second master massage roller 540, and the second driven massage roller 740 can be raised or lowered together. To this end, the first driving cam lobe 112, the first driven cam lobe 312, the second driving cam lobe 512, and the second driven cam lobe 712 can rotate at the same height (phase). That is, the first driving cam protrusion 112 and the first driven cam protrusion 312 can rotate overlapping each other in the first operation mode AM as viewed from the first direction FD. In addition, the second driving cam lobe 512 and the second driven cam lobe 712 can rotate overlapping each other in the first operation mode AM as viewed from the first direction FD. As illustrated in FIG. 7A and 7B, in the first mode AM of operation, the projection 112, the projection 312, the projection 512, and the projection 712 can be rotated while always at the same height.

Meanwhile, in the first operation mode AM, in a state in which the rocking link holding members 150a, 350a, 550a, and 750a are respectively inserted into the rocker openings 130a, 330a, 530a, and 730a, the heights of the rocking rocker 130, 330, 530, and 730 can be changed.

In addition, in a state in which the second driven rocker holding member 750a is inserted into the hole 730a of said rocker and its holding hole 915 of the body 900, the height of the second driven rocker 730 can be changed while held by member 750a.

In fact, since the massage unit 1 for the massage device according to the embodiment of the present invention restricts the movements of the rocking wings 130, 330, 530, and 730 to a predetermined range by the holding members 150a, 350a, 550a, and 750a in the first AM operation mode, operation stability can be improved. massage rollers 140, 340, 540 and 740.

Below with reference to FIG. 8A and 8B describe the operating state for the second mode ZM of operation according to the embodiment of the present invention. It should be understood that the notation for the direction of rotation shown in FIG. 8A and 8B does not mean that the second mode of operation is provided only in a certain direction of rotation, but is shown to distinguish the direction of rotation in the second mode from the direction of rotation in the first mode.

According to an embodiment, in the second mode ZM of operation, the first driving massage roller 140 and the first driven massage roller 340 can be driven in different directions. For example, when the first master massage roller 140 is raised, the first driven massage roller 340 may be lowered.

In the second mode ZM of operation, the first driving massage roller 140 and the first driven massage roller 340 may rotate at different heights. To do this, the protrusion 112 of the first driving cam and the protrusion 312 of the first driven cam can rotate at different heights (phase). For example, the protrusion 112 of the first driving cam and the protrusion 312 of the first driven cam in the second mode ZM of operation may rotate in a state that is out of phase when viewed from the first direction FD. As illustrated in FIG. 8A and 8B, in the second mode ZM of operation, the projection 112 and the projection 312 can be rotated in a state where the phase differs by 180°.

In addition, in the second mode ZM of operation, the second driving massage roller 540 and the second driven massage roller 740 can be rotated at different heights. To do this, the protrusion 512 of the second driving cam and the protrusion 712 of the second driven cam can rotate at different heights (phase). For example, the second driving cam lobe 512 and the second driven cam lobe 712 in the second mode ZM of operation may rotate in a state that is out of phase when viewed from the first direction FD. As illustrated in FIG. 8A and 8B, in the second mode ZM of operation, the projection 512 and the projection 712 can be rotated in a state where the phase differs by 180°.

According to an embodiment, in the second mode of operation ZM, the first driving massage roller 140 and the second driving massage roller 540 can operate in the same direction, and at the same time, the first driven massage roller 340 and the second driven massage roller 740 can operate in the same direction. same direction.

In the second mode ZM of operation, the first driving massage roller 140 and the second driving massage roller 540 can rotate at the same height, and at the same time, the first driven massage roller 340 and the second driven massage roller 740 can rotate at the same height. For example, in the second mode ZM of operation, when the first driving massage roller 140 and the second driving massage roller 540 are raised together, the first driven massage roller 340 and the second driven massage roller 740 can be lowered together. Similarly, when the first driving massage roller 140 and the second driving massage roller 540 are lowered together, the first driven massage roller 340 and the second driven massage roller 740 can be raised together. To this end, the first driving cam lobe 112 and the second driving cam lobe 512 can rotate at the same height (phase), and at the same time, the first driven cam protrusion 312 and the second driven cam protrusion 712 can rotate at the same height (phase).

Meanwhile, in the second operation mode ZM, in a state in which the rocking stage holding members 150a, 350a, 550a, and 750a are respectively inserted into the rocker openings 130a, 330a, 530a, and 730a, the heights of the rocking stages 130, 330, 530, and 730 can be changed. Below is an explanation for each of these cases.

In a state in which the first drive swing link holding member 150a is inserted into said link opening 130a and its holding hole 912 of the body 900, the height of the first leading swing link 130 can be changed while held by the member 150a.

In addition, in a state in which the first driven rocker holding member 350a is inserted into the hole 330a of said rocker and its holding hole 913 of the body 900, the height of the first driven rocker 330 can be changed while held by member 350a.

In addition, in a state in which the second drive rocker holding member 550a is inserted into the hole 530a of said rocker and its holding hole 914 of the body 900, the height of the second drive rocker 530 can be changed while held by member 550a.

In addition, in a state in which the second driven rocker holding member 750a is inserted into the hole 730a of said rocker and its holding hole 915 of the body 900, the height of the second driven rocker 730 can be changed while held by member 750a.

In fact, since the massage module 1 for the massage device according to the embodiment of the present invention restricts the movements of the rocking wings 130, 330, 530, and 730 to a predetermined range by the holding members 150a, 350a, 550a, and 750a in the second operation mode ZM, the operation stability can be improved. massage rollers 140, 340, 540 and 740.

In FIG. 9A and 9C are views showing the first driving rotary part in the first mode of operation as viewed from the first direction, and FIG. 9B and 9D are views showing the first driven turntable in the first mode of operation as viewed from the first direction.

As shown in FIG. 9A and 9C, in the first AM mode of operation, the first transfer gear 200 may be located on one side of the first drive via 121. The first transfer gear 200 may rotate around the first rotation shaft 30 together with the first drive rotation portion 120 in a state in which it is supported on the specified part 120 or on the first leading support surface facing the hole 121.

As shown in FIG. 9B and 9D, in the first AM mode of operation, the first transfer gear 200 may be located on one side of the first driven via 321. The first transfer gear 200 may rotate around the first rotary shaft 30 together with the first driven rotary portion 320 in a state in which it is supported on the specified part 320 or on the first driven support surface facing the hole 321.

Thus, in the first AM mode of operation, the first transition gear 200 is located on one side of the first driving via 121 and on the same side of the first driven via 321, and can rotate together with the first driving rotary part 120 and the first driven rotary part 320, relying on them. .

As described above, in the first mode AM of operation, the protrusion 112 of the first driving cam and the protrusion 312 of the first driven cam can rotate at the same height. This follows from the fact that the groove 120a into which the first driving cam lobe 112 enters and the groove 320a into which the first driven cam lobe 312 enters rotate at the same height relative to each other, as shown in FIG. 9A and 9B. In FIG. 9C and 9D also show that the first driving cam lobe insertion groove 120a and the first driven cam lobe insertion groove 320a rotate at the same height.

The operating states of the second driving rotary part 520 and the second driven rotary part 720 in the first AM operation mode are approximately the same as the above-described states, so detailed descriptions thereof will not be given.

In FIG. 10A and 10C are views showing the first driving rotary part in the second mode of operation as viewed from the first direction, and FIG. 10B and 10D are views showing the first driven turntable in the second mode of operation as viewed from the first direction.

Below with reference to FIG. 10A-10D describe the operating states of the first driving rotary part 120 and the first driven rotary part 320 in the second mode ZM of operation.

As shown in FIG. 10A and 10C, in the second ZM mode of operation, the first transfer gear 200 may be located on the other side of the first drive via 121. The first transfer gear 200 may rotate around the first rotation shaft 30 together with the first drive rotation portion 120 in a state in which it is supported. on the specified part 120 or on the second leading bearing surface located at a distance from the first leading bearing surface.

As shown in FIG. 10B and 10D, in the second ZM mode of operation, the first change gear 200 may be located on the other side of the first driven hole 321. The first change gear 200 can rotate around the first rotation shaft 30 together with the first driven rotation part 320 in a state in which it rests on the specified part 320 or on the second driven support surface located at a distance from the first driven support surface.

Thus, in the second mode ZM of operation, the first transition gear 200 is located on the other side of the first driving via 121 and on the other side of the first driven via 321, and can rotate together with the first driving rotary part 120 and the first driven rotary part 320, relying on them. .

As described above, in the first mode AM of operation, the first driving cam lobe 112 and the first driven cam lobe 312 can rotate in different phases with respect to each other. This follows from the fact that the first driving cam lobe insertion groove 120a and the first driven cam lobe insertion groove 320a are arranged without overlapping each other when viewed from the first direction FD, and rotate while having different phases with respect to each other, as shown in fig. 10A and 10V. In addition, in FIG. 10C and 10D, it is also seen that the groove 120a and the groove 320a are non-overlapping when viewed from the first direction FD, and rotate while having different phases.

The operating states of the second driving rotary part 520 and the second driven rotary part 720 in the second operation mode ZM are approximately the same as the above-described states, so detailed descriptions thereof will not be given.

In FIG. 11A to 11C are views showing the first driving rotary part and the first driven rotary part as viewed from the first direction, and explaining the transition process from the first operation mode to the second operation mode.

Below with reference to FIG. 11A to 11C describe the switching process from the first operation mode AM to the second operation mode ZM.

First, as illustrated in FIG. 11A, in a state in which, in the first mode AM of operation, the first transfer gear 200 is located on one side of the first driving via 121 and on the same side of the first driven transfer groove 321, the direction of rotation of the drive swivel 10 is changed.

Then, as illustrated in FIG. 11B, as the drive swivel 10 rotates, the first drive swivel 120 rotates with it, and the first adapter gear 200 engages with the teeth of the first drive swivel 120 and the teeth of the first driven swivel 320 and rotates along the first drive via 121, and rotates along the first driven transition groove 321.

In this case, the first transition gear 200 rotates in cooperation with the teeth of the first driven rotary part 320, but when the rotation stops, the rotary part 320 stops.

Further, as illustrated in FIG. 11C, as the drive swash plate 10 further rotates, the first drive rotary portion 120 continues to rotate with it, and the first transition gear 200 can rotate to the other side of the first drive via 121 and also rotate to the other side of the first driven transition groove. 321.

When the first transition gear 200 is located on the other side of the hole 121 and on the other side of the groove 321, the gear 200 can rotate together with the first driving rotary part 120 and the first driven rotary part 320, supported by them.

Due to the above-described process, there is a switchover from the first operation mode AM to the second operation mode ZM. Referring to the first driving cam lobe insertion groove 120a and the first driven lobe insertion groove 320a shown in FIG. 11A and the same grooves shown in FIG. 11C, it can be seen that when the first operation mode AM is switched to the second operation mode ZM, the phases of the first driving cam lobe 112 and the first driven cam lobe 312 become different from each other.

In FIG. 12A to 12C are views showing the first driving rotary part and the first driven rotary part as seen from the first direction, and explaining the transition process from the second operation mode to the first operation mode.

Below with reference to FIG. 12A-12C describe the transition process from the second operation mode ZM to the first operation mode AM.

First, as illustrated in FIG. 12A, in a state where, in the second mode ZM of operation, the first transition gear 200 is located on the other side of the first driving via 121 and on the other side of the first driven transition groove 321, the direction of rotation of the driving swivel washer 10 is changed.

Then, as illustrated in FIG. 12B, as the drive swivel 10 rotates, the first drive swivel 120 rotates with it, and the first adapter gear 200 engages with the teeth of the first drive swivel 120 and the teeth of the first driven swivel 320 and rotates along the first drive via 121, and also rotates along the first driven transition groove 321.

In this case, the first transition gear 200 rotates in cooperation with the teeth of the first driven rotary part 320, but when the rotation stops, the rotary part 320 stops.

Further, as illustrated in FIG. 12C, as the drive swivel 10 further rotates, the first drive swivel portion 120 continues to rotate with it, and the first transition gear 200 can rotate toward the first side of the first drive via 121 and also rotate toward the first side of the first driven groove. 321.

When the first adapter gear 200 is located on one side of the hole 121 and on the same side of the groove 321, the gear 200 can rotate together with the first driving rotary part 120 and the first driven rotary part 320, relying on them.

Due to the above-described process, switching from the second operation mode ZM to the first operation mode AM occurs. Referring to the first driving cam lobe insertion groove 120a and the first driven lobe insertion groove 320a shown in FIG. 21A and the same grooves shown in FIG. 12C, it can be seen that when the second operation mode ZM is switched to the first operation mode AM, the phases of the first driving cam lobe 112 and the first driven cam lobe 312 may become the same.

In FIG. 13 shows a rotation sensing sensor in a massage module for a massage device according to an embodiment of the present invention.
