[0095] The leg massage unit 2000 can be configured to massage the user's legs. A leg accommodation space 2100 for accommodating the user's legs can be formed in the leg massage unit 2000.

[0096] The leg massage unit 2000 can include at least one or more of an air cell (not shown), a calf massage module (not shown), and a foot massage unit (not shown).

[0097] The air cell (not shown) can be configured to fix at least a part of the user's body. The air cell included in the leg massage unit 2000 can be configured to be inflated by supplying air from a separately provided air supply unit to fix at least a part of the user's body.

[0098] The calf massage module (not shown) can be configured to massage the calf part in the accommodated user's legs. At this time, the calf massage module can include, as described above, a ball massage unit or a roller massage unit, and is not limited thereto.

[0099] The foot massage part (not shown) can be a configuration for massaging the user's feet. The foot massage part can include a foot massage module for massaging the user's feet. At this time, the foot massage module can include, but is not limited to, a ball massage unit or a roller massage unit.

[0100] Hereinafter, a massage device 100 including a rotatable arm massage part according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0101] FIG. 4 is a diagram schematically showing the main frame 1100 of FIG. 2 equipped with a rotation module 4000 and an arm length adjustment module 5000.

[0102] Referring to FIGS. 1 and 4, a massage device 100 according to an embodiment of the present invention includes a main frame 1100 forming the skeleton of the massage device 100, a body massage part 1000 for massaging the user's body, and both sides of the body massage part 1000 are arranged to accommodate both arms of the user respectively, and an arm massage part 3000 for massaging the user's arms. The main frame 1100 includes an arm fixing frame 1130 to which the arm massage part 3000 is connected, and the arm massage part 3000 can include an arm moving frame 3100 that is rotatable in at least one direction with reference to the arm fixing frame 1130.

[0103] As described above, the body massage part 1000 can be a means for providing a massage to at least a part of the user's body. For example, a space for accommodating at least a part of the user's body can be formed in the body massage part 1000.

[0104] In one embodiment, the accommodation space of the body massage unit 1000 can be a space for the user to sit. That is, the user can sit in the space formed in the body massage unit 1000, and the user can enjoy the massage while sitting.

[0105] The main frame 1100 can be disposed inside the body massage unit 1000 and can be a means for forming the skeleton of the body massage unit 1000.

[0106] In an alternative embodiment, the body massage unit 1000 can include a cover that covers the massage module 1700 disposed inside so that it is not exposed to the outside.

[0107] In an alternative embodiment, the massage device 100 according to an embodiment of the present invention can further include a leg massage unit 2000. The leg massage unit 2000 can be a means for providing a leg massage to the user. For example, the leg massage unit 2000 can include a calf massage unit that massages the calf of the user and / or a foot massage unit that massages the foot of the user.

[0108] The leg massage unit 2000 can be provided with a space for accommodating at least a part of the user's leg. The user can insert the leg into the space formed in the leg massage unit 2000, and the user can receive the massage with the leg inserted into the leg massage unit 2000.

[0109] The arm massage unit 3000 can be a means for providing massage and stretching to the user's arm. For example, the arm massage unit 3000 can include a massage module 1700 for providing a massage to the user's arm.

[0110] On the one hand, as will be described later, the arm massage unit 3000 can provide stretching, other medical treatments, massage, etc. to the user by rotating in at least one direction. Therefore, providing a massage to the user's arm below does not simply mean providing a pressing massage, a pounding massage, or a kneading massage, but should be understood to include stretching and other medical treatments performed by rotating or stretching the user's arm in a specific direction.

[0111] The arm massage units 3000 can be arranged on both sides of the body massage unit 1000. For example, the arm massage units 3000 can be respectively arranged at positions corresponding to the user's upper arms. A space for accommodating the user's arms can be provided in each arm massage unit 3000.

[0112] In one embodiment, the arm massage unit 3000 can include an arm massage unit housing 3300. The arm massage unit housing 3300 can be configured such that the user's arm can be inserted, for example, the user's forearm can be inserted.

[0113] The arm massage unit housing 3300 can be connected to the arm moving frame 3100 to form the arm massage unit 3000. That is, the user can insert the arm into the arm massage unit housing 3300 to receive a massage. As will be described later, when the arm moving frame 3100 rotates, the arm massage unit 3000 can be rotated as a whole while the arm massage unit housing 3300 rotates simultaneously.

[0114] In one embodiment, the main frame 1100 can include an arm fixing frame 1130 to which the arm massaging unit 3000 is connected. For example, the arm fixing frames 1130 can be respectively arranged on both side surfaces of the body massaging unit 1000, and the arm massaging units 3000 can be respectively arranged on the arm fixing frames 1130. Thus, the user can be provided with a massage by inserting both arms into the arm massaging units 3000 while sitting on the body massaging unit 1000.

[0115] In one embodiment, the arm massaging unit 3000 can rotate in at least one direction. Desirably, the arm massaging unit 3000 can rotate in the vertical direction and the horizontal direction with reference to FIG. 4. For this purpose, the massage device 100 according to an embodiment of the present invention can further include a rotation module 4000 for rotating the arm massaging unit 3000 in at least one direction. The rotation module 4000 will be described in detail later.

[0116] FIG. 5 is a diagram showing that the arm massaging unit 3000 rotates in the vertical direction, and FIG. 6 is a diagram for explaining the rotation principle of the arm massaging unit 3000 in FIG. 5.

[0117] Referring to FIGS. 5 and 6, the arm massaging unit 3000 can rotate in the vertical direction. For example, the arm massaging unit 3000 can rotate in the vertical direction while accommodating the user's arms in a state where the user is sitting on the massage device 100.

[0118] For this purpose, the main frame 1100 can have the arm fixing frames 1130 arranged on both sides, and the arm massaging units 3000 can be coupled to the arm fixing frames 1130. At this time, the arm massaging unit 3000 can include an arm moving frame 3100 that is rotatable in the vertical direction with reference to the arm fixing frame 1130.

[0119] Therefore, with the arm massage unit 3000 connected to the arm fixing frame 1130, the arm moving frame 3100 can rotate in the vertical direction with respect to the arm fixing frame 1130, and the arm massage unit 3000 can rotate in the vertical direction.

[0120] In an alternative embodiment, the arm fixing frame 1130 can extend toward the front of the user so as to have a length in a state where the user is seated on the massage device 100. Therefore, even when the user's arm is placed on the arm massage unit 3000, the arm fixing frame 1130 can sufficiently withstand the load of the user's arm. Also, since the force generated by the rotation module 4000 can be efficiently transmitted to the arm massage unit 3000, the arm massage unit 3000 can be stably rotated.

[0121] In an alternative embodiment, the arm massage units 3000 on both sides may be independently rotatable. For example, when one arm massage unit 3000 rotates in the vertical direction, the other arm massage unit 3000 may not rotate or may rotate in the horizontal direction. Alternatively, the angles, intensities, and speeds at which the arm massage units 3000 on both sides rotate in the vertical direction can be different from each other. For this purpose, the rotation modules 4000 can be respectively arranged on both sides of the body massage unit 1000 so as to correspond to the pair of arm massage units 3000. Also, the rotation modules 4000 can be independently controlled and operated to enable the arm massage units 3000 on both sides to rotate independently.

[0122] FIG. 7 is a diagram showing the arm massage unit 3000 rotating in different directions, and FIG. 8 is a diagram for explaining the rotation principle of the arm massage unit 3000 in FIG. 7.

[0123] Referring to FIGS. 7 and 8, the arm massage unit 3000 can rotate in the horizontal direction. For example, the arm massage unit 3000 can rotate in the horizontal direction while accommodating the user's arm in a state where the user is seated on the massage device 100.

[0124] For this purpose, as described above, the main frame 1100 can have the arm fixing frames 1130 arranged on both sides, and the arm massage unit 3000 can be coupled to the arm fixing frames 1130. At this time, the arm massage unit 3000 can include an arm moving frame 3100 that is rotatable in the left - right direction with respect to the arm fixing frame 1130.

[0125] Therefore, with the arm massage unit 3000 connected to the arm fixing frame 1130, the arm moving frame 3100 can rotate in the left - right direction with respect to the arm fixing frame 1130, and the arm massage unit 3000 can rotate in the left - right direction.

[0126] In an alternative embodiment, the arm fixing frame 1130 can extend toward the front of the user so as to have a length when the user is seated on the massage device 100. Thus, even when the user's arm is placed on the arm massage unit 3000, the arm fixing frame 1130 can sufficiently withstand the load of the user's arm. Also, since the force generated by the rotation module 4000 can be efficiently transmitted to the arm massage unit 3000, the arm massage unit 3000 can be rotated stably.

[0127] Also, as described above, in an alternative embodiment, the arm massage units 3000 on both sides may be independently rotatable. For example, when one side's arm massage unit 3000 rotates in the left - right direction, the other side's arm massage unit 3000 may not rotate or may rotate in the up - down direction. Or, the angles, intensities, and speeds at which the arm massage units 3000 on both sides rotate in the left - right direction can be different from each other. For this purpose, the rotation module 4000 can be arranged on both sides of the body massage unit 1000 so as to correspond to the pair of arm massage units 3000. Also, the rotation module 4000 can be independently controlled and operated to enable the arm massage units 3000 on both sides to rotate independently.

[0128] In this way, by rotating the arm massage unit 3000 in the vertical or horizontal direction, it is possible to provide a stretch to the user's arm or provide a rehabilitation exercise function to the user's arm. For example, the arm massage unit 3000 can rotate the user's arm in the vertical or horizontal direction while accommodating the user's arm to provide a stretch function. Alternatively, when the user's arm is injured, the arm massage unit 3000 can provide a rehabilitation function so that rehabilitation exercises can be performed by rotating while accommodating the user's arm. Alternatively, the user may provide an exercise function by manually rotating the arm massage unit 3000 in a state where the rotation module 4000 is not driven. That is, since the arm massage unit 3000 is configured to rotate in the vertical and horizontal directions, the user can be made to perform a muscle strength exercise by manually rotating the arm massage unit 3000.

[0129] In an alternative embodiment, the arm massage unit 3000 can further include a load sensor for measuring a load. For example, the load sensor can measure the force applied from the rotation module 4000 to rotate the arm massage unit 3000, and when the force is equal to or greater than a preset value, it can recognize that the user's arm has been rotated by the limit value beyond which it can no longer rotate, and send a control signal to the control unit 1200 to stop the rotation of the arm massage unit 3000. Further, the load sensor can measure the load applied to the arm massage unit 3000 by the user's arm, and when the force is equal to or greater than a preset value, it can recognize that the user wants to manually control the arm massage unit 3000 and send a control signal to the control unit 1200 to change the rotation operation of the arm massage unit 3000 to the manual mode.

[0130] In yet another alternative embodiment, the arm massage unit 3000 can further include a pinching prevention sensor that senses when at least a part of the user's body is pinched. For example, when the pinching prevention sensor senses that the user's body is pinched at a predetermined position while the arm massage unit 3000 is rotating, the pinching prevention sensor can send a control signal to the control unit 1200 to stop the rotation of the arm massage unit 3000. Accordingly, the safety for the user's body can be further improved.

[0131] FIG. 9 is a diagram showing the rotation module 4000 of FIG. 4.

[0132] Referring to FIG. 9, the massage device 100 according to an embodiment of the present invention can further include a rotation module 4000 for rotating the arm massage unit 3000 in at least one direction.

[0133] In one embodiment, the rotation module 4000 can include a first rotation module 4100 that rotates the arm massage unit 3000 in the vertical direction with reference to FIG. 9, and a second rotation module 4200 that rotates the arm massage unit 3000 in the horizontal direction. At this time, the first rotation module 4100 and the second rotation module 4200 can be driven by an actuator on a base.

[0134] Here, the arm massage unit 3000 can include the arm movement frame 3100 as described above, and the first rotation module 4100 and the second rotation module 4200 can rotate the arm massage unit 3000 by rotating the arm movement frame 3100. Detailed content regarding this will be described later.

[0135] In one embodiment, the rotation module 4000 can include a support plate 4300 that is disposed between the first rotation module 4100 and the second rotation module 4200, with one surface connected to the first rotation module 4100 and the other surface connected to the second rotation module 4200.

[0136] The support plate 4300 can be formed in a plate shape having a width. With reference to FIG. 9, a first rotation module 4100 can be connected to the upper part of the support plate 4300, and a second rotation module 4200 can be connected to the lower part of the support plate 4300.

[0137] The first rotation module 4100 can be connected and fixed to the upper part of the support plate 4300. That is, the support plate 4300 can support the first rotation module 4100 so that the first rotation module 4100 is fixed at a predetermined position by being coupled to the first rotation module 4100.

[0138] Specifically, the first rotation module 4100 is disposed on the upper part of the support plate 4300 and can be disposed behind the elbow when the user is seated on the massage device 100. That is, the first rotation module 4100 is disposed on the upper part of the support plate 4300 and disposed behind the user's elbow, so that when the arm massage unit 3000 rotates left and right or up and down, it is not obstructed by the first rotation module 4100 and can be disposed to have spatial efficiency in the massage device 100.

[0139] The second rotation module 4200 can be connected to the lower part of the support plate 4300, and the support plate 4300 can be rotated by the second rotation module 4200. For example, the second rotation module 4200 can rotate the support plate 4300, whereby the first rotation module 4100 connected to the upper part of the support plate 4300 rotates together to rotate the arm massage unit 3000 left and right.

[0140] Specifically, the second rotation module 4200 is disposed at the lower part of the support plate 4300, can be disposed on both side surfaces of the massage device 100, and can be disposed below the user's forearm. That is, the second rotation module 4200 is disposed at the lower part of the support plate 4300 and is disposed below the user's forearm on both sides of the massage device 100, so that when the arm massage part 3000 rotates left and right or up and down, it will not be obstructed by the second rotation module 4200, and can be disposed to have spatial efficiency in the massage device 100.

[0141] In addition, the detailed content regarding the drive of the second rotation module 4200 will be described later.

[0142] In this way, the arm massage part 3000 can rotate in both the up-and-down and left-and-right directions, and the arm massage parts 3000 on both sides can rotate independently of each other. Therefore, by driving the rotation in the up-and-down and left-and-right directions simultaneously, a stretching function and an exercise function that cause the user to stretch can be provided.

[0143] FIG. 10 is a diagram showing the first rotation module 4100 of FIG. 9, FIG. 11 is a diagram showing the first rotation module 4100 of FIG. 9 as viewed from another angle, and FIG. 12 is a diagram for explaining the driving principle of the first rotation module 4100 of FIG. 9.

[0144] Referring to FIGS. 10 to 12, the first rotation module 4100 can include a first rotation actuator 4110 that generates power for rotating the arm massage part 3000 in the up-and-down direction, and a support frame 4120 that extends from the support plate 4300 toward one side and is connected to the arm movement frame 3100.

[0145] The first rotation actuator 4110 may be a linear actuator that expands and contracts in a predetermined direction. For example, the first rotation actuator 4110 can be supplied with power and linearly driven by the supplied power.

[0146] The first rotary actuator 4110 can be connected to the arm movement frame 3100 and can rotate the arm movement frame 3100 up and down by expanding and contracting in one direction.

[0147] In one embodiment, the arm movement frame 3100 can include an arm connection part 3110, a rotation part 3120 that is connected to the first rotary actuator 4110 and rotates, and an extension part 3130 that connects the arm connection part 3110 and the rotation part 3120.

[0148] The arm connection part 3110 can be a part connected to the arm massage part housing 3300.

[0149] The arm connection part 3110 can extend along the longitudinal direction of the arm massage part 3000, and the arm connection part 3110 can be coupled to the arm massage part housing 3300 of the arm massage part 3000. Therefore, when the arm movement frame 3100 rotates by the first rotary actuator 4110, the arm massage part 3000 can rotate as a whole. Further, since the arm connection part 3110 extends along the longitudinal direction of the arm massage part 3000, it can be fastened to the arm massage part housing 3300 at a plurality of parts, so that the connection between the arm connection part 3110 and the arm massage part housing 3300 can be made more firm.

[0150] The rotation part 3120 may be configured to be connected to the first rotary actuator 4110 and the support frame 4120 and rotated by the drive of the first rotary actuator 4110.

[0151] Specifically, the rotating part 3120 can be rotatably connected to the first rotating actuator 4110 at one position and can be connected to the support frame 4120 at another position. At this time, the position where the rotating part 3120 is connected to the first rotating actuator 4110 can be a part that is connected so as to be rotatable by the expansion and contraction of the first rotating actuator 4110. Also, the part where the rotating part 3120 is connected to the support frame 4120 can be fixed, and thereby, this part can become the rotation axis AR1 of the rotating part 3120.

[0152] When the rotating part 3120 rotates, the extension part 3130 and the arm connecting part 3110 connected to the rotating part 3120 can rotate together. That is, when the rotating part 3120 rotates by the first rotating actuator 4110, the arm moving frame 3100 can rotate in the vertical direction as a whole, and the arm massage part 3000 can rotate in the vertical direction.

[0153] The extension part 3130 can be a part that connects the arm connecting part 3110 and the rotating part 3120. That is, when the rotating part 3120 rotates by the first rotating actuator 4110, the extension part 3130 can transmit the rotational force to the arm connecting part 3110.

[0154] At this time, the extension part 3130 can extend downward from the rotating part 3120 toward the arm connecting part 3110 with the arm massage part 3000 not being rotated with reference to FIG. 10. Therefore, even when the first rotating actuator 4110 expands and contracts vertically, the rotational force due to the expansion and contraction can be easily transmitted to the arm connecting part 3110 disposed relatively downward.

[0155] Referring to FIG. 12 again, when explaining the driving principle of the first rotating module 4100, the arm moving frame 3100 can rotate in the vertical direction by the expansion and contraction of the first rotating actuator 4110.

[0156] Specifically, when the first rotary actuator 4110 contracts, the rotating part 3120 can rotate clockwise with reference to FIG. 12. At this time, the part where the support frame 4120 and the rotating part 3120 are connected can be the rotation axis AR1 of the rotating part 3120.

[0157] Conversely, when the first rotary actuator 4110 extends, the rotating part 3120 can rotate counterclockwise with reference to FIG. 12. At this time, the part where the support frame 4120 and the rotating part 3120 are connected can similarly be the rotation axis AR1 of the rotating part 3120. As a result, the extension part 3130 and the arm connecting part 3110 rotate counterclockwise, enabling the arm massaging part 3000 to rotate downward.

[0158] In an alternative embodiment, the arm moving frame 3100 can further include a first stopper 3200. For example, the rotating part 3120 of the arm moving frame 3100 can be provided with the first stopper 3200.

[0159] The first stopper 3200 can be a means for determining the limit of the upward rotation of the arm moving frame 3100.

[0160] Specifically, the first stopper 3200 can be disposed on at least one of the left and right sides of the rotating part 3120 with reference to FIG. 10. The first stopper 3200 is disposed on the left and right sides of the rotating part 3120, but can extend outward and be a member having a width.

[0161] Therefore, when the rotating part 3120 rotates in the direction of lifting the user's arm by the first rotation actuator 4110, the first stopper 3200 can move in the direction toward the support frame 4120 while rotating together. At this time, when the rotating part 3120 rotates to the maximum extent, as shown in FIG. 12, the first stopper 3200 can contact the support frame 4120, thereby preventing further rotation. At this time, the upward rotation limit of the rotating part 3120 is determined by the position where the first stopper 3200 is arranged on the rotating part 3120.

[0162] In an alternative embodiment, the first rotation module 4100 can further include a second stopper 4130. The second stopper 4130 can be arranged on the support frame 4120 of the first rotation module 4100. The second stopper 4130 can be a means for determining the downward rotation limit of the arm movement frame 3100.

[0163] Specifically, the second stopper 4130 can be arranged on the path along which the extension part 3130 rotates and can be arranged to connect both sides of the support frame 4120, and can be arranged at the position where the extension part 3130 rotates to the maximum extent in the direction in which the user's arm drops. Thereby, when the extension part 3130 rotates in the direction in which the user's arm drops and is blocked by the second stopper 4130, it can no longer rotate, and the point in time when the extension part 3130 and the second stopper 4130 come into contact is the position where the extension part 3130 rotates to the maximum extent.

[0164] FIG. 13 is a diagram showing the second rotation module 4200 of FIG. 9, and FIG. 14 is a diagram showing the second rotation module 4200 of FIG. 9 as viewed from another angle. FIG. 15 is a diagram for explaining an embodiment in which the second rotation module 4200 of FIG. 9 is provided with a bearing 4250, and FIG. 16 is a diagram for explaining the driving principle of the second rotation module 4200 of FIG. 9.

[0165] Referring to FIGS. 13 to 16, the second rotation module 4200 can include a second rotation actuator 4210 that generates power for rotating the arm massage unit 3000 in the left - right direction.

[0166] The second rotation actuator 4210 can be a linear actuator that expands and contracts in a predetermined direction. For example, the second rotation actuator 4210 can be supplied with power and linearly driven by the supplied power.

[0167] The second rotation actuator 4210 can expand and contract in a direction different from that of the first rotation actuator 4110. That is, since the direction in which the first rotation actuator 4110 expands and contracts is different from the direction in which the second rotation actuator 4210 expands and contracts, the arm massage unit 3000 can be rotated in different directions respectively.

[0168] The second rotation actuator 4210 can be connected to the support plate 4300 and can rotate the support plate 4300 by expanding and contracting in one direction. As a result, the first rotation module 4100 connected to the support plate 4300 can rotate together, and the arm massage unit 3000 connected to the first rotation module 4100 can also rotate left and right together. At this time, the support plate 4300 and the first rotation module 4100 can be connected so as to be fixed to each other, so that when the support plate 4300 rotates, the first rotation module 4100 can rotate itself, and the arm massage unit 3000 connected to the first rotation module 4100 can also rotate together.

[0169] The support plate 4300 and the second rotation module 4200 can be connected at a plurality of positions.

[0170] Specifically, the second rotary actuator 4210 can be coupled by the support plate 4300 and the first connecting portion 4220. Therefore, when the second rotary actuator 4210 linearly expands and contracts, the second rotary actuator 4210 and the first connecting portion 4220 will rotate relative to each other.

[0171] At this time, in order for the support plate 4300 to rotate due to the linear drive of the second rotary actuator 4210, a rotation axis is required.

[0172] For this purpose, the second rotary actuator 4210 can be coupled by the support plate 4300 and the second connecting portion 4230. At this time, the second connecting portion 4230 can become the rotation axis AR2 of the support plate 4300. In order for the second connecting portion 4230 to function as the rotation axis AR2, its position must not change regardless of the drive of the second rotary actuator 4210. Therefore, the second connecting portion 4230 can be connected and fixed to the arm fixing frame 1130.

[0173] The second rotation module 4200 can further include a connecting plate 4240 that connects the first connecting portion 4220 and the second connecting portion 4230. For example, the connecting plate 4240 can be extended to have a length, and the first connecting portion 4220 and the second connecting portion 4230 can be arranged at both ends. Therefore, when the first connecting portion 4220 moves by the second rotary actuator 4210, the second connecting portion 4230 is fixed in a fixed position and the connecting plate 4240 can rotate, whereby the support plate 4300 can easily rotate.

[0174] Referring to FIG. 16 to explain the driving principle of the second rotation module 4200, when the second rotation actuator 4210 extends in one direction, the second connecting portion 4230 is fixed as the rotation axis AR2 of the support plate 4300, and the first connecting portion 4220 is pushed out to the right with reference to FIG. 16 as the second rotation actuator 4210 extends, so as to rotate the support plate 4300. As a result, the support plate 4300 rotates counterclockwise, and the first rotation module 4100 connected thereto rotates, so that the arm massage portion 3000 rotates.

[0175] Conversely, when the second rotation actuator 4210 contracts in the opposite direction, the second connecting portion 4230 is fixed as the rotation axis AR2 of the support plate 4300, and the first connecting portion 4220 is pulled to the left with reference to FIG. 16 as the second rotation actuator 4210 contracts, so as to rotate the support plate 4300. As a result, the support plate 4300 rotates clockwise, and the first rotation module 4100 connected thereto rotates, so that the arm massage portion 3000 rotates.

[0176] In one embodiment, a virtual extension line AX1 along which the arm fixing frame extends in the longitudinal direction and a virtual extension line AX2 along which the second rotation actuator 4210 of the second rotation module 4200 extends and contracts can intersect each other in order to rotate the support plate 4300 by the operation of the second rotation actuator 4210. That is, the longitudinal extension line AX1 of the arm fixing frame and the extension line AX2 in the extending and contracting direction of the second rotation actuator 4210 are not arranged side by side with each other. In this way, the two extension lines intersect each other, so that the support plate 4300 can be easily rotated by the extension and contraction of the second rotation actuator 4210.

[0177] In an alternative embodiment, the rotation module 4000 can further include a bearing 4250 disposed between the second rotation module 4200 and the support plate 4300. The bearing 4250 can generally be formed in the shape of a base plate with a through hole formed therein.

[0178] The bearing 4250 may be disposed between the second rotation module 4200 and the support plate 4300 to adjust the center of gravity of the support plate 4300 to which the first rotation module 4100 is coupled. For example, the first rotation module 4100 is disposed on the upper part of the support plate 4300, so that a certain load or more may be applied to the support plate 4300. Also, in order for the support plate 4300 to rotate by the second rotation module 4200, the support plate 4300 and the second rotation module 4200 must be spaced apart by a certain distance. Therefore, if the support plate 4300 and the second rotation module 4200 are spaced apart from each other and no separate member is interposed in the space between them, the support plate 4300 may tilt in one direction due to the load of the support plate 4300, or a problem may occur in that the shaft portion to which it is connected may be bent.

[0179] To solve this problem, a bearing 4250 is disposed between the second rotating module 4200 and the support plate 4300 to prevent the support plate 4300 from being deflected to one side.

[0180] FIG. 17 is a diagram for explaining the arm length adjustment module 5000 of FIG. 4, and FIG. 18 is a diagram showing a state where the arm massage part housing 3300 is removed from FIG.

[0181] 17 and 18, the massage device 100 according to an embodiment of the present invention may include an arm length adjustment module 5000 for adjusting the length of the arm massage part 3000.

[0182] The arm massage unit 3000 can accommodate the user's arm, for example, the user's forearm. To this end, the arm massage unit 3000 can include an arm massage unit housing 3300 that can accommodate the user's forearm. The arm massage unit housing 3300 can be provided with a space into which the user's forearm can be inserted, and the user can receive a massage after inserting the forearm into this space.

[0183] Therefore, the arm length adjustment module 5000 can adjust the length of the arm massage unit 3000 by moving the position of the arm massage unit housing 3300 back and forth. That is, with the user's forearm inserted into the arm massage unit housing 3300, the arm massage unit housing 3300 can move back and forth, and since the other components are fixed in their original positions, the length of the arm massage unit 3000 can be adjusted.

[0184] The arm length adjustment module 5000 can include an arm length adjustment motor 5200 that generates power to move the arm massage unit housing 3300, a first moving member 5320 that transmits the power generated from the arm length adjustment motor 5200 to the arm massage unit housing 3300, and a first connection bracket 5110 that connects the first moving member 5320 and the arm massage unit housing 3300.

[0185] In one embodiment, the arm length adjustment motor 5200 can be a means for being supplied with power to generate rotation. At this time, the arm length adjustment motor 5200 can be connected to the lead screw 5310, and when the arm length adjustment motor 5200 rotates, the lead screw 5310 connected thereto can also rotate together.

[0186] Threads can be formed on the surface of the lead screw 5310. The lead screw 5310 can be arranged to penetrate through a through hole formed in the first moving member 5320, and a groove that meshes with the threads formed on the surface of the lead screw 5310 can be formed in the through hole of the first moving member 5320. Thus, when the lead screw 5310 rotates, the first moving member 5320 can move correspondingly.

[0187] The lead screw 5310 can be extended in a direction arranged along the moving direction of the arm massage unit housing 3300. Thereby, the lead screw 5310 can provide power to the first moving member 5320 and at the same time guide the moving direction of the first moving member 5320.

[0188] In an alternative embodiment, the arm length adjustment motor 5200 may be a type of motor including an air cylinder. For example, the arm length adjustment motor 5200 can directly linearly move the first moving member 5320 by using an air cylinder. At this time, threads may not be formed on the surface of the lead screw 5310, and the lead screw 5310 can perform the function of guiding the moving direction of the first moving member 5320.

[0189] In one embodiment, the arm length adjustment module 5000 can further include a guide rod 5410 and a second moving member 5420 that are arranged on one side of the arm connecting portion 3110 of the arm moving frame 3100 to guide the moving direction of the arm massage unit housing 3300.

[0190] The guide rod 5410 can be a means for guiding the moving direction of the arm massage unit housing 3300.

[0191] The guide rod 5410 can be extended so as to have a length in a direction arranged parallel to the lead screw 5310. Therefore, the direction in which the arm massage unit housing 3300 moves and the extending direction of the guide rod 5410 may be parallel.

[0192] The second moving member 5420 can be a means for moving along the direction in which the guide rod 5410 extends. The second moving member 5420 can include a through hole for the guide rod 5410 to pass through. That is, the guide rod 5410 is arranged to penetrate the second moving member 5420, and the second moving member 5420 can move along the direction in which the guide rod 5410 extends.

[0193] The wrist length adjustment module 5000 can further include at least one second connection bracket 5120 that connects the second moving member 5420 and the wrist massage unit housing 3300. The second connection bracket 5120 can be a means for connecting the second moving member 5420 and the wrist massage unit housing 3300.

[0194] Therefore, when the first moving member 5320 and the wrist massage unit housing 3300 connected to the first moving member 5320 are moved by the wrist length adjustment motor 5200, the second moving member 5420 connected to the wrist massage unit housing 3300 can move simultaneously with the wrist massage unit housing 3300. At this time, the second moving member 5420 can guide the moving direction of the wrist massage unit housing 3300 by moving along the guide rod 5410.

[0195] The second connection bracket 5120 can be provided corresponding to the number of the second moving members 5420.

[0196] FIG. 19 is a diagram for explaining an embodiment in which a wrist position recognition sensor 5500 is provided in the wrist length adjustment module 5000 of FIG. 17.

[0197] Referring to FIG. 19, the wrist length adjustment module 5000 can include a wrist position recognition sensor 5500 that recognizes the position of the wrist massage unit 3000.

[0198] The wrist position recognition sensor 5500 can be arranged at least one or more on one side of the wrist connection portion 3110 of the wrist moving frame 3100. For example, a plurality of wrist position recognition sensors 5500 can be arranged along the longitudinal direction of the wrist connection portion 3110.

[0199] In one embodiment, the arm position recognition sensor 5500 can be a photosensor. For example, the arm position recognition sensor 5500 can include a groove, and the first connection bracket 5110 can further include a protrusion 5111 that passes through the groove of the arm position recognition sensor 5500.

[0200] Specifically, when the first moving member 5320 moves by the arm length adjustment motor 5200, the first connection bracket 5110 can move together with the first moving member 5320. As a result, the protrusion formed on the first moving member 5320 can move along the moving direction of the first moving member 5320. At this time, the protrusion can pass through the arm position recognition sensor 5500, and the arm position recognition sensor 5500 can recognize whether the protrusion has passed through.

[0201] When the arm position recognition sensor 5500 recognizes that the protrusion has passed through, it can send a recognition signal therefor to the control unit 1200. Thereby, the control unit 1200 can grasp the position of the arm massage unit housing 3300 based on the information recognized by the arm position recognition sensor 5500. For example, if it is recognized by the arm position recognition sensor 5500 whether the protrusion has passed through, the control unit 1200 can grasp the position of the arm massage unit housing 3300 based on this.

[0202] Therefore, when the massage device 100 is not driven, the arm massage unit 3000 can be arranged at a fixed position. Also, when the arm length adjustment module 5000 adjusts the length of the arm massage unit 3000, it becomes possible to grasp how much the length of the arm massage unit 3000 has been extended or contracted.

[0203] FIG. 20 is a diagram for explaining the position of the first rotation actuator 4110.

[0204] Referring to FIG. 20, the first rotation actuator 4110 of the first rotation module 4100 is disposed above the support plate 4300 and can be disposed to expand and contract vertically.

[0205] At this time, since the first rotation actuator 4110 expands and contracts vertically, it can be disposed in the vertical direction with respect to the support plate 4300. Therefore, the load of the first rotation actuator 4110 can be concentrated and applied to a relatively narrow area of the support plate 4300. In this way, when the load is biased only to a specific part of the support plate 4300, there is a problem that the support plate 4300 may bend or the support plate 4300 may tilt, and the durability of the rotation module 4000 may be reduced.

[0206] To solve this problem, the first rotation actuator 4110 can be disposed on a virtual extension line extending along the rotation axis AR2 of the support plate 4300. For example, the first rotation actuator 4110 can be disposed at a position adjacent to the second connection portion 4230 among the connection portions between the support plate 4300 and the second rotation module 4200. Therefore, as described above, since the second connection portion 4230 is connected to the arm fixing frame 1130, the load applied by the first rotation module can be more withstand, and the first rotation actuator 4110 can be stably supported by the support plate 4300.

[0207] FIG. 21 is a diagram for explaining the change in the length of the arm massaging unit 3000 according to the angle of the arm.

[0208] Referring to FIG. 21, due to the structure of the human body, when a person is sitting comfortably, it is natural for the arm to be bent with the elbow as a reference. However, when the arm is lifted upward or rotated outward, it is natural for the arm to be spread with the elbow as a reference. Furthermore, this is even more so when stretching the user's arm.

[0209] Therefore, it is desirable that the distance L1 from the shoulder to the wrist in a state where the user does not rotate the arm is shorter than the distance L2 from the shoulder to the wrist in a state where the user raises or rotates the arm outward. That is, when the user's arm is raised or rotated outward, it is desirable that the length of the arm massage unit 3000 is controlled to increase in order to compensate for the increased distance.

[0210] For this purpose, the massage device 100 according to an embodiment of the present invention can include a control unit 1200 that controls the operation of the massage device 100, and the control unit 1200 can control the arm length adjustment module 5000 to adjust the length of the arm massage unit 3000 based on the rotation amount of the arm massage unit 3000.

[0211] That is, the control unit 1200 can control the arm length adjustment module 5000 so that the user's arm naturally spreads when the arm massage unit 3000 rotates in the vertical or horizontal direction. Specifically, the control unit 1200 can recognize the degree to which the arm massage unit 3000 is rotated, and can control the arm length adjustment module 5000 so that the length of the arm massage unit 3000 increases by the corresponding amount.

[0212] Therefore, the user can rotate the arm stably, and can safely receive stretching and motor functions from the massage device 100.

[0213] The embodiments of the present disclosure have been described in more detail with reference to the attached drawings. However, the present disclosure is not necessarily limited to these embodiments, and can be variously modified and implemented without departing from the technical idea of the present disclosure. Therefore, the embodiments disclosed in the present disclosure are not for limiting the technical idea of the present disclosure, but for explanation, and the scope of the technical idea of the present disclosure is not limited by these embodiments. Therefore, it must be understood that the embodiments described above are illustrative in all respects and not restrictive.
