4 is a view for explaining that the leg massage unit 2000 of FIG. 1 rotates independently.

Referring to FIG. 4 , the massage device 100 according to an embodiment of the present invention includes a body massage unit 1000 and a body massage unit 1000 that accommodate at least a part of the user's body and massage the user's body. It may include a leg massage unit 2000 disposed at one end to massage the user's legs.

The leg massage unit 2000 may be provided to correspond to both legs of the user. For example, the leg massage unit 2000 may include a first leg massage unit 2000a corresponding to one leg of the user and a second leg massage unit 2000b corresponding to the other leg of the user. In this case, the first leg massager 2000a may correspond to the user's right leg, and the second leg massager 2000b may correspond to the user's left leg. However, this is distinguished for convenience, and the first leg massager 2000a may correspond to the user's left leg, and the second leg massager 2000b may correspond to the user's right leg.

The first leg massage unit 2000a and the second leg massage unit 2000b may be independently controlled, and specifically, the first leg massage unit 2000a and the second leg massage unit 2000b may be independently rotated. have. That is, the first leg massager 2000a and the second leg massager 2000b can move independently of each other, and accordingly, the user receives different massages on both legs or alternately massages both legs as needed. can be provided. In addition, the user may receive stretching or massage due to rotation of both legs. In this case, the massage device 100 may rotate both legs of the user simultaneously or independently.

Figure 5 is a view for explaining the principle of rotation of the conventional leg massage unit.

Referring to FIG. 5 , a conventional massage device includes a leg angle actuator 240 for rotating the leg massage unit 200 .

The leg angle actuator 240 may be disposed inside the body massage unit 1000 and is connected to, for example, the main frame 1100 .

The leg angle actuator 240 may be driven to extend in one direction, whereby the leg massage unit 200 is rotated. The leg angle actuator 240 includes a link member 230 that is in contact with the leg massage unit 200 at one end and transmits power to the leg massage unit 200 . At this time, the link member 230 includes a wheel at a portion in contact with the leg massage unit 200 .

The leg massage unit 200 includes a leg frame 210 disposed on a rear side and a leg support 220 connected to the leg frame 210 and providing a path for the wheel of the link member 230 to move.

Accordingly, as the leg angle actuator 240 expands and contracts, the wheel of the link member 230 can roll along the leg support 220, and thus the leg massage unit 200 connected to the leg support 220 rotates. You can do it.

As described above, the conventional leg massage unit 200 employs a structure in which a wheel disposed on one side of the link member 230 moves along the leg support 220 by driving the leg angle actuator 240 to rotate. was doing In this case, in order for the leg massage unit 200 to be rotated at an angle greater than or equal to a predetermined range, the leg angle actuator 240 must have a wide extension range, so a relatively large leg angle actuator 240 is required. Therefore, due to the nature of massage devices used indoors, there is a difficulty in designing the arrangement of actuators. In addition, in the case of the above-described type, a problem may occur in that the rotation of the leg massage unit 200 is not relatively smooth.

6 is a view for explaining a driving module of the leg massage unit 2000 according to an embodiment of the present invention, and FIG. 7 is an enlarged view of part A of FIG. 6 .

6 and 7, the massage device according to an embodiment of the present invention includes a main frame 1100 forming a skeleton of the massage device, a body massage unit 1000 for massaging the user's body, the The leg massage unit 2000 including a first leg massage unit 2000a corresponding to one leg of the user and a second leg massage unit 2000b corresponding to the other leg of the user and the body massage unit 1000 It may include a driving module that is disposed and rotates the leg massage unit 2000 .

At this time, the main frame, the body massage unit, and the leg massage unit may selectively apply the contents of the main frame 1100, the body massage unit 1000, and the leg massage unit 2000 described above or modify them as necessary. have.

The first leg massage unit 2000a and the second leg massage unit 2000b may be independently rotated, and for this purpose, the driving module includes a first driving module for rotating the first leg massage unit 2000a and a second leg massager. A second driving module for rotating the unit 2000b may be included.

Hereinafter, in describing the driving of the leg massage unit 2000 according to the present embodiment, the term “leg massage unit 2000” refers to the first leg massage unit 2000a and the second leg massage unit 2000b, That the leg massage unit 2000 may include a certain configuration may mean that each of the first leg massage unit 2000a and the second leg massage unit 2000b may include that configuration.

In addition, in describing the driving module according to the present embodiment, referring to the driving module refers to the first driving module and the second driving module, and that the driving module may include a certain configuration refers to the first driving module and the second driving module. It can mean that each module can contain its components.

A driving module according to this embodiment may be a driving module according to a motor type.

As an example, the drive module may include a leg angle motor 2110 , a power transmission member 2120 and a pulley 2130 .

The leg angle motor 2110 may be a means for generating rotational force for rotating the leg massage unit 2000 by receiving electric power.

The leg angle motor 2110 may be disposed in the body massage unit 1000 and may be specifically connected to the main frame 1100 .

The leg massage unit 2000 may include a shaft member forming a rotation axis for rotation. The shaft member may be disposed on one side of the leg massage unit 2000, and may be disposed adjacent to the user's knee, for example. Accordingly, the leg massage unit 2000 can rotate with the shaft member as an axis by receiving force from the leg angle motor 2110 .

As an embodiment, the leg angle motor 2110 may be disposed lower than the shaft member, and specifically, lower than the leg connection frame. Accordingly, the leg angle motor 2110 can be disposed at a position relatively close to the leg massage unit 2000, and a space in the body massage unit 1000 in which the leg angle motor 2110 is disposed can be secured.

The power transmission member 2120 may be a means for transmitting rotational force generated from the leg angle motor 2110 to the leg massage unit 2000 . For example, the leg angle motor 2110 may include a gear rotated by receiving power, and the power transmission member 2120 may contact the gear and rotate together to correspond to the rotation of the gear.

As an example, the power transmission member 2120 may be a timing belt. Accordingly, the timing belt may include teeth meshing with gears, and accordingly, rotational force generated from the leg angle motor 2110 may be easily transmitted.

As an optional embodiment, the power transmission member 2120 may be made of a rubber material. As another example, the power transmission member 2120 may be made of a metal material, and may be, for example, a chain including metal.

The pulley 2130 may be a means for transmitting rotational force transmitted from the power transmission member 2120 to the leg massage unit 2000 .

The pulley 2130 may be installed to interlock with the shaft member of the leg massage unit 2000, and may be coupled to each other to rotate together with the shaft member, for example.

Therefore, the pulley 2130 can rotate together with the shaft member by the rotational force transmitted from the power transmission member 2120, and thus the leg massager 2000 can rotate.

The power transmission member 2120 may be disposed to surround at least a portion of the gear and pulley 2130 of the leg angle motor 2110 . Therefore, even if the leg angle motor 2110 and the pulley 2130 are separated by a predetermined distance, the rotational force generated from the leg angle motor 2110 may be transmitted to the pulley 2130.

As an alternative embodiment, the diameter of the gear of the leg angle motor 2110 may be smaller than the diameter of the pulley 2130. Accordingly, when the gear rotates relatively much, the pulley 2130 rotates relatively little, so that the leg massage unit 2000 rotates slowly.

That is, even when the leg angle motor 2110 rotates rapidly, the pulley 2130 can rotate slowly, and accordingly, the leg massage unit 2000 can also rotate slowly, and the user's safety using the massage device can be improved. be able to secure In addition, the leg massage unit 2000 can rotate smoothly to provide a comfortable feeling to the user.

FIG. 8 is a view for explaining the rotation principle of the leg massage unit 2000 of FIG. 6 .

Referring to FIG. 8 , the power transmission member 2120 may be rotated together by driving the leg angle motor 2110 . For example, the power transmission member 2120 may rotate together to correspond to the direction of rotation of a gear disposed at one end of the leg angle motor 2110 .

Specifically, when the gear of the leg angle motor 2110 rotates clockwise based on FIG. 8 , the power transmission member 2120 may rotate clockwise to correspond to the rotation direction of the leg angle motor 2110, Accordingly, the pulley 2130 connected to the power transmission member 2120 may also rotate clockwise to correspond thereto. Accordingly, the leg massage unit 2000 may also rotate clockwise to correspond to the rotation direction of the pulley 2130, and eventually the leg massage unit 2000 may be lifted.

Conversely, when the gear of the leg angle motor 2110 rotates counterclockwise based on FIG. 8 , the power transmission member 2120 may rotate counterclockwise to correspond to the rotation direction of the leg angle motor 2110, Accordingly, the pulley 2130 connected to the power transmission member 2120 may also rotate counterclockwise to correspond thereto. Therefore, the leg massage unit 2000 may also rotate counterclockwise to correspond to the rotation direction of the pulley 2130, and eventually the leg massage unit 2000 comes down.

9 is a view for explaining a drive module of a leg massage unit 2000 according to another embodiment of the present invention, FIG. 10 is an enlarged view of part B of FIG. 9, and FIG. 11 is a view showing the drive module of FIG. It is a schematic drawing.

9 to 11, the massage device according to another embodiment of the present invention includes a main frame 1100 forming a skeleton of the massage device, a body massage unit 1000 for massaging the user's body, the The leg massage unit 2000 including a first leg massage unit 2000a corresponding to one leg of the user and a second leg massage unit 2000b corresponding to the other leg of the user and the body massage unit 1000 It may include a driving module that is disposed and rotates the leg massage unit 2000 .

At this time, the main frame, the body massage unit, and the leg massage unit may selectively apply the contents of the main frame 1100, the body massage unit 1000, and the leg massage unit 2000 described above or modify them as necessary. have.

The first leg massage unit 2000a and the second leg massage unit 2000b may be independently rotated, and for this purpose, the driving module includes a first driving module for rotating the first leg massage unit 2000a and a second leg massager. A second driving module for rotating the unit 2000b may be included.

Hereinafter, in describing the driving of the leg massage unit 2000 according to the present embodiment, the term “leg massage unit 2000” refers to the first leg massage unit 2000a and the second leg massage unit 2000b, That the leg massage unit 2000 may include a certain configuration may mean that each of the first leg massage unit 2000a and the second leg massage unit 2000b may include that configuration.

In addition, in describing the driving module according to the present embodiment, referring to the driving module refers to the first driving module and the second driving module, and that the driving module may include a certain configuration refers to the first driving module and the second driving module. It can mean that each module can contain its components.

The driving module according to the present embodiment may be a driving module using a motor and a screw.

As an example, the drive module may include a leg angle motor 2210, a power transmission member 2220, a lead screw 2230, a screw pulley housing 2240, and a wheel 2250.

The leg angle motor 2210 may be a means for generating rotational force for rotating the leg massager 2000 by receiving electric power.

The leg angle motor 2210 may be disposed in the body massaging unit 1000 and may be connected to, for example, the main frame 1100 . At this time, as will be described later, in order for the screw pulley housing 2240 to move up and down by the leg angle motor 2210, a space must be secured within the body massage unit 1000 in which the screw pulley housing 2240 can move up and down. For this purpose, it is preferable that the leg angle motor 2210 is disposed relatively below.

Therefore, for this purpose, the main frame 1100 may further include a driving frame to which the driving module is connected. Specifically, the driving frame may be installed to extend from the main frame 1100 toward the lower surface. A support having a width may be disposed at one end of the driving frame, and a leg angle motor 2210, a lead screw 2230, and a screw pulley housing 2240 may be connected to the support.

The power transmitting member 2220 may be a means for transmitting rotational force generated from the leg angle motor 2210 to the lead screw 2230 . For example, the leg angle motor 2210 may include a gear rotated by receiving electric power, and the power transmission member 2220 may contact the gear and rotate together to correspond to the rotation of the gear.

As an example, the power transmission member 2220 may be a timing belt. Accordingly, the timing belt may include teeth meshing with gears, and accordingly, rotational force generated from the leg angle motor 2210 may be easily transmitted.

As an optional embodiment, the power transmission member 2220 may be made of a rubber material. As another example, the power transmission member 2220 may be made of a metal material, and may be, for example, a chain including metal.

The lead screw 2230 may receive power from the power transmission member 2220 to rotate, and may be a means for lifting and moving the screw pulley housing 2240 by rotation.

As an example, a rotation unit disposed to be in contact with the power transmission member 2220 may be disposed at one end of the lead screw 2230 .

That is, the power transmission member 2220 may contact both the leg angle motor 2210 and the rotating part of the lead screw 2230 to transmit rotation generated by the leg angle motor 2210 to the lead screw 2230.

As an alternative embodiment, the diameter of the gear of the leg angle motor 2210 may be smaller than the diameter of the rotating part. Accordingly, when the gear rotates relatively much, the rotating part rotates relatively little, so that the rotation of the leg massage unit 2000 can be performed slowly.

That is, even when the leg angle motor 2210 rotates rapidly, the lead screw 2230 can rotate slowly, and accordingly, the leg massage unit 2000 can also rotate slowly. Safety can be ensured In addition, the leg massage unit 2000 can rotate smoothly to provide a user with a comfortable feeling of use.

The screw pulley housing 2240 may be a means for rotating the leg massage unit 2000 while moving up and down along the lead screw 2230 by rotation of the lead screw 2230 . In this case, the screw pulley housing 2240 may include a through hole through which the lead screw 2230 is inserted, and the lead screw 2230 may pass through the screw pulley housing 2240 .

A spiral groove may be formed on a surface of the lead screw 2230 , and a screw thread may be formed on a surface of the through hole formed in the screw pulley housing 2240 to engage with the spiral groove formed in the lead screw 2230 .

Accordingly, as the lead screw 2230 rotates, the screw pulley housing 2240 may move up and down by the screw thread engaged with the lead screw 2230 .

Since the screw pulley housing 2240 is moved up and down by the rotation of the lead screw 2230, the lift and move direction of the screw pulley housing 2240 may be parallel to the longitudinal direction of the lead screw 2230.

As an optional embodiment, the driving frame may be formed to have a length parallel to the moving direction of the screw pulley housing 2240 . That is, the driving frame and the lead screw 2230 may extend parallel to each other. In addition, a guide groove may be formed along the length of one surface of the driving frame, and the screw pulley housing 2240 may include a protrusion inserted into the guide groove. Therefore, when the screw pulley housing 2240 moves up and down, the protrusion can move along the guide groove. That is, the driving frame can guide the moving direction of the screw pulley housing 2240 .

The wheel 2250 may be a means that is disposed on one side of the screw pulley housing 2240 and rolls along one side of the leg massage unit 2000 .

As an embodiment, the leg massage unit 2000 may further include a leg support unit 2260 disposed on a rear surface, and the wheel 2250 may move along the leg support unit 2260 . Specifically, the leg support 2260 may be disposed on the rear surface of the leg massage unit 2000 and extend along the longitudinal direction of the leg massage unit 2000 .

When the screw pulley housing 2240 moves up and down as the lead screw 2230 rotates, the wheel 2250 may lift the leg massager 2000 while rolling along the leg support 2260 . That is, the leg support 2260 may provide a path along which the wheel 2250 can move while rolling.

As an optional embodiment, the leg support 2260 may include a curved surface corresponding to the wheel 2250 so that the wheel 2250 does not deviate from the path while moving. For example, the support portion may include a curved surface concave inward to allow the wheel 2250 to be seated therein, and the wheel 2250 may move while rolling while being seated on the concave curved surface.

As such, the screw pulley housing 2240 does not directly lift the leg massager 2000 while moving up and down, but lifts it using the rotation of the wheel 2250, so that the leg massager 2000 can rotate smoothly. , it is possible to provide a user with a comfortable feeling of use.

FIG. 12 is a view for explaining the rotation principle of the leg massage unit 2000 of FIG. 9 .

Referring to FIG. 12 , the screw pulley housing 2240 may move up and down by driving the leg angle motor 2210 . For example, the direction of movement of the screw pulley housing 2240 may depend on the direction of rotation of the leg angle motor 2210.

At this time, the rotation direction of the leg angle motor 2210 and the movement direction of the screw pulley housing 2240 may be determined according to the direction of the spiral formed in the lead screw 2230. That is, when the direction of the spiral formed in the lead screw 2230 is formed in the opposite direction, the rotation direction of the leg angle motor 2210 and the movement direction of the screw pulley housing 2240 may be opposite to each other.

Specifically, when the leg angle motor 2210 rotates in a predetermined direction, the lead screw 2230 may rotate in a corresponding direction. Due to the rotation of the lead screw 2230, the screw pulley housing 2240 may move in a direction corresponding thereto, and may, for example, rise. Accordingly, the wheel 2250 disposed on one side of the screw pulley housing 2240 may move while rolling on the surface of the leg support 2260, and the leg massage unit 2000 may be lifted.

Conversely, when the leg angle motor 2210 rotates in the opposite direction, the lead screw 2230 may also rotate in the corresponding direction. By the rotation of the lead screw 2230, the screw pulley housing 2240 may move in a corresponding direction, for example, may descend. Accordingly, the wheel 2250 disposed on one side of the screw pulley housing 2240 moves while rolling on the surface of the leg support 2260, so that the leg massage unit 2000 comes down.

As an embodiment, the leg massage unit 2000 may include a leg support unit 2330 disposed on a rear surface of the leg massage unit 2000 . In this case, the leg support 2330 may be connected to the link unit 2320. Therefore, as the leg angle actuator 2310 expands and contracts, the link unit 2320 can move together, and the leg support 2330 connected to the link unit 2320 moves, so that the leg massager 2000 can rotate.

The link unit 2320 may have a joint structure. For example, the link unit 2320 may include a bent portion 2321 , and the link unit 2320 may be folded based on the bent portion 2321 . Accordingly, the leg angle actuator 2310 may stably rotate the leg massage unit 2000 .

And, accordingly, the link unit 2320 can rotate in a direction away from the main frame 1100 . At the same time, the link unit 2320 may be unfolded based on the bent portion 2321, and the leg massager 2000 may be lifted while the link unit 2320 is unfolded.

Conversely, when the leg angle actuator 2310 contracts, the link unit 2320 connected to the leg angle actuator 2310 may rotate in a direction perpendicular to the leg angle actuator 2310, that is, in a counterclockwise direction, , Accordingly, the link unit 2320 may rotate in a direction closer to the main frame 1100 .

As an alternative embodiment, the airbag 2410 may be coupled such that one side contacts the airbag support 2420 . For example, one side of the airbag 2410 may completely contact the airbag support 2420, and thus, when the airbag 2410 is inflated, the airbag 2410 is firmly fixed to the airbag support 2420 to massage the leg. The unit 2000 can be stably lifted.

FIG. 17 is a view for explaining the rotation principle of the leg massage unit 2000 of FIG. 15 .

Referring to FIG. 17 , as an optional embodiment, a plurality of airbags 2410 may be provided, and an airbag support 2420 may be formed in a stepped shape to correspond to the number of airbags 2410 provided.

Referring to FIG. 17 , a plurality of airbags 2410 may be disposed in a vertical direction, and airbag supporters 2420 may have steps formed in a direction away from the leg massager 2000 from bottom to top. At this time, as the angle between the leg massager 2000 and the airbag supporter 2420 is smaller, the airbag 2410 disposed at the lower end is involved.

For example, when the leg massage unit 2000 is lifted from a maximally folded state, the lowermost airbag 2410 may be inflated. After that, after the leg massage unit 2000 is lifted to some extent, the lowermost airbag 2410 is spaced apart from the leg support unit 2430 of the leg massage unit 2000, and from then on, the lowermost airbag 2410 is disposed at the top. As the airbag 2410 expands, the leg massager 2000 is lifted. Accordingly, an angle at which the leg massager 2000 can be maximally lifted may be determined by the airbag 2410 disposed at the top.

Conversely, when the leg massage unit 2000 is lowered, the airbag 2410 disposed at the top may be involved. For example, in a state in which the leg massager 2000 is maximally lifted, only the airbag 2410 disposed at the top comes into contact with the leg massager 2000. Then, as the airbag 2410 disposed on the uppermost stage contracts, the leg massaging unit 2000 is lowered, and when the leg massaging unit 2000 descends beyond a predetermined angle, the airbag 2410 disposed on the next stage and A leg support 2430 is disposed. As such, as the leg massage unit 2000 is lowered, the leg support unit 2430 comes into contact with the airbag 2410 disposed at a relatively lower end.

18 is a diagram for explaining a leg massage unit 2000 according to another embodiment of the present invention.

Referring to FIG. 18 , the massage device according to the present embodiment may include a buffer member 2510. For example, the leg massage unit 2000 may include a buffer member 2510 disposed on the rear surface.

Specifically, the initial position may be a position in a folded state of the leg massage unit 2000 . At this time, the position adjustment sensor 1810 may recognize whether the folded leg massage unit 2000 is at a predetermined position at a specific time point.

As an example, the position adjustment sensor 1810 may recognize whether the first leg massager 2000a and the second leg massager 2000b are positioned side by side. That is, the position adjustment sensor 1810 may recognize whether the first leg massager 2000a and the second leg massager 2000b are rotated to have a deviation from each other when they are in their initial positions.

To this end, the position adjustment sensor 1810 may be provided in each of the first leg massage unit 2000a and the second leg massage unit 2000b. Specifically, the position adjustment sensor 1810 may be disposed on the side where the first leg massage unit 2000a and the second leg massage unit 2000b face each other.

As an optional embodiment, each of the position adjustment sensors 1810 disposed in the first leg massage unit 2000a and the second leg massage unit 2000b may recognize each other, and recognize that they do not face each other at the correct position. In this case, the position adjustment sensor 1810 may recognize that the two leg massage units 2000 are displaced from each other.

As an embodiment, the leg massage unit 2000 may further include a positioning frame 2520.

The position setting frame 2520 may be a means for setting the first leg massage unit 2000a and the second leg massage unit 2000b to be disposed in the correct position.

As an embodiment, the positioning frame 2520 may be disposed connected to the main frame 1100, and specifically disposed below the main frame 1100, corresponding to the heel portion of the leg massage unit 2000. can be placed in a location.

Accordingly, when the leg massage unit 2000 comes into contact with the positioning frame 2520, it may be determined that the leg massage unit 2000 is located in the initial position.

As an optional embodiment, the position setting frame 2520 may be disposed at a position in contact with the buffer member 2510. Accordingly, when the leg massager 2000 is folded and returns to its initial position, the buffer member 2510 may contact the positioning frame 2520. That is, when the shock absorbing member 2510 contacts the position setting frame 2520, an initial position of the leg massage unit 2000 may be set while alleviating shock due to folding of the leg massage unit 2000.
