Hereinafter, a massage device including an independently driven leg massage unit according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 4 is a diagram 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 portion 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. At this time, the first leg massage unit 2000a may correspond to the user's right leg, and the second leg massage unit 2000b may correspond to the user's left leg. However, this distinction is made for convenience, and the first leg massage unit 2000a may correspond to the user's left leg, and the second leg massage unit 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 rotated independently. there is.

Additionally, the user may be provided with stretching or massage by rotating both legs. In this case, the massage device 100 may rotate both legs of the user simultaneously or independently.

Figure 5 is a diagram for explaining the principle of rotation of a 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 placed inside the body massage unit 1000 and, for example, connected to the main frame 1100.

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

The leg massage unit 200 includes a leg frame 210 disposed at the rear and a leg support unit 220 that is connected to the leg frame 210 and provides a path along which the wheel of the link member 230 moves.

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

As described above, the conventional leg massage unit 200 adopts a structure in which the wheel disposed on one side of the link member 230 can be rotated by moving along the leg support unit 220 by driving the leg angle actuator 240. was doing According to this, in order for the leg massage unit 200 to rotate at an angle greater than a predetermined range, the extension range of the leg angle actuator 240 must be wide, so a relatively large leg angle actuator 240 is required. Therefore, due to the nature of the massage device used indoors, there are difficulties in designing the arrangement of the actuator. Additionally, when using the above-described type, a problem may occur in that the leg massage unit 200 does not rotate relatively smoothly.

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

Referring to FIGS. 6 and 7, the massage device according to an embodiment of the present invention includes a main frame 1100 that forms the skeleton of the massage device, a body massage unit 1000 that massages the user's body, the A leg massage unit 2000 and the body massage unit 1000 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. It may include a driving module that is disposed to rotate the leg massage unit 2000.

At this time, the main frame, body massage unit, and leg massage unit can selectively apply the contents of the main frame 1100, body massage unit 1000, and leg massage unit 2000 described above, or modify them as needed. there is.

The first leg massage unit 2000a and the second leg massage unit 2000b can be rotated independently, and for this purpose, the drive module includes a first drive module that rotates the first leg massage unit 2000a and a second leg massage unit. It may include a second driving module that rotates the unit 2000b.

Hereinafter, in explaining the operation of the leg massage unit 2000 according to this 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 the first leg massage unit 2000a and the second leg massage unit 2000b may each include that configuration.

Additionally, in describing the driving module according to this embodiment, the term “driving module” refers to the first driving module and the second driving module, and the fact that the driving module may include any configuration refers to the first driving module and the second driving module. This may mean that each module may contain its own configuration.

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

As an example, the driving 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 to rotate the leg massage unit 2000 by receiving power.

The leg angle motor 2110 may be placed 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, for example, adjacent to the user's knee. Accordingly, the leg massage unit 2000 can rotate around the shaft member by receiving force from the leg angle motor 2110.

As an example, the leg angle motor 2110 may be disposed lower than the shaft member, and specifically may be disposed lower than the leg connection frame. Accordingly, the leg angle motor 2110 can be placed relatively close to the leg massage unit 2000, and a space for the leg angle motor 2110 to be placed within the body massage unit 1000 can be secured.

The power transmission member 2120 may be a means for transmitting the 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 that is rotated by receiving power, and the power transmission member 2120 may be in contact with 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 that mesh with the gear, and thus can easily transmit the rotational force generated from the leg angle motor 2110.

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, for example, a chain containing metal.

The pulley 2130 may be a means of transmitting the rotational force received 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, for example, may be coupled to each other to rotate together with the shaft member.

Accordingly, 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 massage unit 2000 can rotate.

The power transmission member 2120 may be arranged to surround at least a portion of the gear and pulley 2130 of the leg angle motor 2110. Accordingly, 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 can be transmitted to the pulley 2130.

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

That is, even when the leg angle motor 2110 rotates quickly, the pulley 2130 can rotate slowly, and thus the leg massage unit 2000 can also rotate slowly, increasing the safety of the user using the massage device. can be secured. Additionally, the leg massage unit 2000 can rotate smoothly, providing a comfortable feeling to the user.

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

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

Specifically, when the gear of the leg angle motor 2110 rotates clockwise with respect to 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 to this. Accordingly, the leg massage unit 2000 can also rotate clockwise to correspond to the rotation direction of the pulley 2130, and eventually the leg massage unit 2000 can be lifted.

Conversely, when the gear of the leg angle motor 2110 rotates counterclockwise with respect to 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 to this. Accordingly, the leg massage unit 2000 can also rotate counterclockwise to correspond to the rotation direction of the pulley 2130, and eventually the leg massage unit 2000 comes down.

FIG. 9 is a diagram for explaining the driving module of the 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 diagram showing the driving module of FIG. 9. This is a schematic drawing.

9 to 11, a massage device according to another embodiment of the present invention includes a main frame 1100 that forms the skeleton of the massage device, a body massage unit 1000 that massages the user's body, the A leg massage unit 2000 and the body massage unit 1000 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. It may include a driving module that is disposed to rotate the leg massage unit 2000.

At this time, the main frame, body massage unit, and leg massage unit can selectively apply the contents of the main frame 1100, body massage unit 1000, and leg massage unit 2000 described above, or modify them as needed. there is.

The first leg massage unit 2000a and the second leg massage unit 2000b can be rotated independently, and for this purpose, the drive module includes a first drive module that rotates the first leg massage unit 2000a and a second leg massage unit. It may include a second driving module that rotates the unit 2000b.

Hereinafter, in explaining the operation of the leg massage unit 2000 according to this 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 the first leg massage unit 2000a and the second leg massage unit 2000b may each include that configuration.

Additionally, in describing the driving module according to this embodiment, the term “driving module” refers to the first driving module and the second driving module, and the fact that the driving module may include any configuration refers to the first driving module and the second driving module. This may mean that each module may contain its own configuration.

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

As one embodiment, 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 to rotate the leg massage unit 2000 by receiving power.

The leg angle motor 2210 may be placed in the body massage unit 1000 and, for example, may be connected to the main frame 1100. At this time, in order for the screw pulley housing 2240 to move up and down by the leg angle motor 2210, as described later, a space for the screw pulley housing 2240 to move up and down must be secured within the body massage unit 1000. And for this purpose, the leg angle motor 2210 is preferably disposed relatively lower.

Accordingly, 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 bottom. A support having an area 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 transmission member 2220 may be a means for transmitting the 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 that is rotated by receiving power, and the power transmission member 2220 may be in contact with 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 that mesh with the gear, and thus can easily transmit the rotational force generated from the leg angle motor 2210.

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, for example, a chain containing metal.

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

As an example, a rotating part that is in contact with the power transmission member 2220 may be disposed on one end of the lead screw 2230.

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

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

That is, even when the leg angle motor 2210 rotates quickly, the lead screw 2230 can rotate slowly, and accordingly, the leg massage unit 2000 can also rotate slowly, and the user using the massage device can In addition, safety can be ensured, and the leg massage unit 2000 can rotate smoothly, providing a comfortable feeling to the user.

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. At this time, the screw pulley housing 2240 may include a through hole into which the lead screw 2230 is inserted, and the lead screw 2230 may be arranged to penetrate the screw pulley housing 2240.

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

Accordingly, as the lead screw 2230 rotates, the screw pulley housing 2240 can move up and down by the thread engaging with it.

Since the screw pulley housing 2240 moves up and down by the rotation of the lead screw 2230, the direction of up and down movement of the screw pulley housing 2240 may be parallel to the longitudinal direction of the lead screw 2230.

As an optional embodiment, the drive frame may be formed to have a length parallel to the direction of movement of the screw pulley housing 2240. That is, the driving frame and the lead screw 2230 may be formed to extend parallel to each other. Additionally, a guide groove may be formed along the length of one surface of the drive 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 disposed on one side of the screw pulley housing 2240 and roll along one side of the leg massage unit 2000.

As an example, the leg massage unit 2000 may further include a leg support unit 2260 disposed on the rear surface, and the wheel 2250 may move along the leg support unit 2260. Specifically, the leg support unit 2260 is disposed on the back of the leg massage unit 2000 and may be formed to 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 roll along the leg support part 2260 and lift the leg massage part 2000. That is, the leg support 2260 may provide a path along which the wheel 2250 can roll and move.

As an optional embodiment, the leg support portion 2260 may include a curved surface corresponding to the wheel 2250 to prevent the wheel 2250 from deviating from its path while moving. For example, the support portion may include a concave curved surface toward the inside so that the wheel 2250 can be seated, and the wheel 2250 may roll and move while seated on the concave curved surface.

In this way, the screw pulley housing 2240 does not directly lift the leg massage unit 2000 while moving up and down, but lifts it using the rotation of the wheel 2250, so that the leg massage unit 2000 can rotate smoothly. , It can provide users with a comfortable feeling of use.

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

Referring to FIG. 12, the screw pulley housing 2240 can be moved 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 on the lead screw 2230. That is, when the direction of the spiral formed on 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 the corresponding direction. As the lead screw 2230 rotates, the screw pulley housing 2240 can move in a corresponding direction, for example, rise. Accordingly, the wheel 2250 disposed on one side of the screw pulley housing 2240 can move while rolling on the surface of the leg support part 2260, and the leg massage part 2000 can 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 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 part 2260, and the leg massage part 2000 comes down.

Figure 13 is a diagram for explaining the driving module of the leg massage unit 2000 according to another embodiment of the present invention.

Referring to FIG. 13, a massage device according to another embodiment of the present invention includes a main frame 1100 that forms the skeleton of the massage device, a body massage unit 1000 that massages the user's body, and a body massager 1000 that massages the user's body.

The first leg massage unit 2000a and the second leg massage unit 2000b can be rotated independently, and for this purpose, the drive module includes a first drive module that rotates the first leg massage unit 2000a and a second leg massage unit. It may include a second driving module that rotates the unit 2000b.

Hereinafter, in explaining the operation of the leg massage unit 2000 according to this 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 the first leg massage unit 2000a and the second leg massage unit 2000b may each include that configuration.

Additionally, in describing the driving module according to this embodiment, the term “driving module” refers to the first driving module and the second driving module, and the fact that the driving module may include any configuration refers to the first driving module and the second driving module. This may mean that each module may contain its own configuration.

The leg angle actuator 2310 may be a means for generating force to rotate the leg massage unit 2000 by receiving power. For example, the leg angle actuator 2310 may be a means of expanding and contracting in the longitudinal direction when supplied with power, and rotating the leg massage unit 2000 by expanding and contracting.

The leg angle actuator 2310 may be disposed on the body massage unit 1000 and, for example, may be connected to the main frame 1100.

The link unit 2320 may be a means of transmitting the force generated from the leg angle actuator 2310 to the leg massage unit 2000 to lift the leg massage unit 2000. To this end, the link unit 2320 may be connected to the leg massage unit 2000 and the leg angle actuator 2310.

As an example, the leg massage unit 2000 may include a leg support unit 2330 disposed on the back of the leg massage unit 2000. At this time, the leg support unit 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 unit 2330 connected to the link unit 2320 moves, so the leg massage unit 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 can stably rotate the leg massage unit 2000.

Specifically, the link unit 2320 may be connected to the main frame 1100, the leg angle actuator 2310, and the leg support unit 2330. At this time, each connection portion of the link unit 2320 may be connected to be rotatable. Therefore, when the leg angle actuator 2310 expands and contracts, the link unit 2320 is folded based on the bent portion 2321 and includes a portion connected to the main frame 1100, a portion connected to the leg angle actuator 2310, and a leg support portion ( 2330) and the connected parts can each rotate.

This can be done, 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 can be unfolded based on the bent portion 2321, and as the link unit 2320 is unfolded, the leg massage unit 2000 can be lifted.

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, counterclockwise. , Accordingly, the link unit 2320 can rotate in a direction closer to the main frame 1100. At the same time, the link unit 2320 can be folded based on the bent portion 2321, and as the link unit 2320 is folded, the leg massage unit 2000 comes down.
