[0080] The massage device 100 may include at least one airbag (not shown). The airbag may be located in at least one of the following areas of the body massage section 101 (e.g., in the entire area of ​​the body massage section 101, at least one of the areas corresponding to the user u's shoulder, the pelvis, and the waist, etc.), at least one of the following areas of the arm massage section 102, at least one of the following areas of the leg massage section 103, etc., but is not limited thereto, and may be provided in multiple parts of the massage device 100.

[0081] The massage device 100 may include an air supply unit that supplies air to an airbag to inflate it. The air supply unit may be located inside the body massage unit 101 or in the leg massage unit 103. Alternatively, the air supply unit may be located in the arm massage unit 102. Alternatively, the air supply unit may be located outside the massage device 100.

[0082] The frame portion 110 forms the framework of the internal structure of the body massage portion 101. In terms of defining the overall shape of the massage device 100, the frame portion 110 can be referred to as the "main frame." The frame portion 110 can be made of metal or plastic materials, etc. For example, the frame portion 110 can be made of iron, alloys, steel, etc., but is not limited to these, and can also be made of various hard materials.

[0083] The massage device 100 may include a massage module (not shown).

[0084] The massage module can be disposed inside the body massage unit 101 to provide any form of mechanical stimulation to the user u accommodated in the body massage unit 101. The massage module may include at least one actuator.

[0085] like Figure 1 As shown, the massage module can move along the frame portion 110 disposed inside the body massage unit 101. In other words, the massage module can massage at least a part of the user u's body (or provide massage to at least a part of the user u's body) while moving along the frame portion 110.

[0086] A rack gear may be provided in the frame portion 110 of the body massage unit 101, allowing the massage module to provide mechanical stimulation to various parts of the user's body while moving along the rack.

[0092] The leg massage unit 103 includes a receiving space for accommodating the user u's legs and can provide leg massage to the user u by massaging at least a portion of the user u's legs. For example, the leg massage unit 103 may include a calf massage unit for massaging the user u's lower legs and / or a foot massage unit for massaging the user u's feet.

[0093] The leg massage unit 103 can adjust its length according to the user's body characteristics. For example, when a tall user uses the massage device 100, the leg massage unit 103 needs to be longer because of the longer calves. Conversely, when a short user uses the massage device 100, the leg massage unit 103 needs to be shorter because of the shorter calves. Therefore, the leg massage unit 103 can provide a leg massage customized to the user's height.

[0094] The leg massage unit 103 can provide a leg rest 1031. The user's legs can be accommodated in the leg rest 1031.

[0095] The leg massage unit 103 may include multiple airbags. According to one embodiment, when the user u rests his / her leg on the leg rest 1031, the position of the user's leg can be stably fixed by the inflation of the airbags, and the leg massage unit 103 can provide leg massage by applying pressure to the leg.

[0096] A massage module, including at least one massage unit selected from ball massage units and roller massage units, may also be provided on the leg massage unit 103. According to one embodiment, when the user u rests his / her legs on the leg rest unit 1031, the massage module can be driven to provide leg massage, either additionally or instead of inflating the airbag.

[0097] The seat area 104 provided in the massage device 100 may include: an upper body support for supporting the upper body of the user; and a lower body support for supporting the lower body of the user. The upper body support can contact and support the user's upper body (specifically from the head to the back), and the lower body support can contact and support the user's body in the area below the upper body support (buttocks, thighs, etc.).

[0098] The user input unit 140 can receive commands related to the motion control of the massage device 100 from the user u. The user input unit 140 can be implemented in various forms. For example, the user input unit 140 can be provided in the body massage unit 101, the arm massage unit 102, or the leg massage unit 103. However, it is not limited to these.

[0099] The massage device 100 can obtain various commands from the user through the user input unit 140. For example, the massage device 100 can receive any command regarding the selection of massage module, massage mode, massage intensity, massage time, massage area, position and movement of body massage unit 101, on / off power supply of massage device 100, whether to activate heating function, and audio source playback, but is not limited to these.

[0100] The massage device 100 may include an audio output module 150. The audio output module 150 may be located in various positions. For example, the audio output module 150 may include, but is not limited to, multiple output units such as an upper audio output unit disposed at the upper end of the seat area 104 that contacts the user sitting on the massage device 100, a front audio output unit attached to the front end of the arm massage section 102 on the left / right side of the seat area 104, and / or a rear audio output unit attached to the rear end of the arm massage section 102.

[0101] In this case, the audio output module 150 can provide stereo sound such as 5.1 channels, but is not limited to this.

[0102] According to one embodiment of the present invention, a user can control a massage device 100 using a massage device control device 200. The massage device control device 200 can be connected to the massage device 100 via wired and / or wireless communication.

[0105] Figure 2 This is a diagram illustrating a massage device according to an embodiment of the present invention.

[0106] The frame portion 110 may form a massage device (e.g.: Figure 1 The frame of the massage device 100 is configured as follows. For example, the frame portion 110 may be configured as the frame that forms the body massage portion 101.

[0107] The frame portion 110 may include a body frame 111 and a base frame 112 supporting the body frame 111. The body frame 111 is disposed on the base frame 112 and may be referred to as the "upper frame" to indicate support for the upper body of the user u. A massage module may be provided on the body frame 111.

[0108] A rack 111a may be provided on at least a portion of the body frame 111. The rack 111a may be a component for guiding the up-and-down movement of the massage module. The rack 111a may include multiple valleys and multiple ridges.

[0109] According to one embodiment, racks 111a can be arranged facing each other on both sides of the body frame 111. Furthermore, the massage module can be configured to move along the racks 111a.

[0110] exist Figure 2 In the design, rack 111a is formed in the vertical direction, but is not limited thereto. Rack 111a may include racks in the front-to-back direction and racks in the vertical direction.

[0111] The massage module may include gears that mesh with rack 111a. More specifically, the massage module may include gears that mesh with racks in the forward-backward direction and racks in the up-down direction, respectively. The gears are rotated by an actuator disposed on the massage module, which can move the massage module forward, backward, upward, and / or downward.

[0112] As the massage module moves forward, the massage intensity can increase. Conversely, as the massage module moves backward, the massage intensity can decrease. "Moving forward" means the massage module moves towards the user, and "moving backward" means the massage module returns to its original position before moving towards the user.

[0113] The rack 111a is made of metal and / or plastic materials. For example, the rack 111a may be made of iron, steel, alloy, reinforced plastic, melamine resin, phenolic resin, etc., but is not limited to these.

[0114] Although the present invention discloses a rack 111a as a component for guiding the movement of the massage module, according to embodiments, the massage device 100 may include a track structure provided additionally and / or in place of the rack 111a.

[0115] The body frame 111 can be implemented in various shapes. For example, depending on the shape, the body frame 111 can be divided into S-frame, L-frame, S&L-frame, double S&L-frame, but is not limited to these.

[0116] An S-frame refers to a frame in which at least a portion of the body frame 111 includes a shape that is curved like an "S". An L-frame refers to a frame in which at least a portion of the body frame 111 includes a shape that is curved like an "L". An S&L frame refers to a frame that includes both a shape that is curved like an "S" and a shape that is curved like an "L". A double S&L frame refers to a frame that includes a shape that is curved like an "L" and two parts that are curved like an "S".

[0117] The base frame 112 refers to the portion of the frame 110 that supports the body frame 111 and contacts the ground. The base frame 112 may include an upper base frame 112a and a lower base frame 112b.

[0118] The upper base frame 112a can support the body frame 111, and the lower base frame 112b can contact the ground. In addition, the upper base frame 112a can be connected to the lower base frame 112b.

[0119] According to one embodiment of the present invention, the upper base frame 112a can move along the lower base frame 112b. For example, the upper base frame 112a can slide forward and / or backward along the lower base frame 112b. In this case, the body frame 111 is connected to the upper base frame 112a and can move with the movement of the upper base frame 112a.

[0120] For example, when the upper base frame 112a moves forward, the body frame 111 can also move forward together; when the upper base frame 112a moves backward, the body frame 111 can also move backward together. Therefore, a body massage section (e.g., Figure 1 The body massage section 101) slides.

[0121] Specifically, to enable the upper frame 112a of the base to move, a caster wheel may be provided at the lower part of the upper frame 112a. Additionally, a guide member may be provided at the upper part of the lower frame 112b of the base to guide the caster wheel. The caster wheel on the upper frame 112a moves along the guide member on the lower frame 112b of the base, thereby allowing the upper frame 112a to move forward and / or backward.

[0122] According to another embodiment of the present invention, the massage device 100 may not provide a sliding function. In this case, the base frame 112 may not be separated into an upper frame and a lower frame.

For example, the massage device 100 can be controlled by controlling the operation of the actuators included in the massage module 170.

[0127] The control unit 120 can be implemented by one processor and / or multiple processors. When the control unit 120 is implemented by multiple processors, at least some of the multiple processors can be located at a physical distance from each other. However, the control unit 120 is not limited to this and can be implemented in various ways.

[0128] For example, the control unit 120 may include one and / or more processors. The processor may be implemented by an array of multiple logic gates, or by a combination of a general-purpose microprocessor and a memory storing a program executable in the microprocessor. Furthermore, as will be understood by those skilled in the art to which this embodiment pertains, it may also be implemented in other forms of hardware. For example, the control unit 120 may be implemented using at least one of application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic units for performing functions.

[0129] The control unit 120 can control the operation of the massage device 100 by controlling multiple actuators.

[0130] For example, the massage device 100 may include at least one of the following: a motion actuator that moves the massage module 170 along the frame portion 110; at least one actuator included in the massage module 170; a back angle actuator; an actuator that moves the armrest frame support portion; a leg angle actuator; a foot massage actuator; a leg length adjustment actuator; and a sliding actuator.

[0131] The motion actuator of the massage module 170 can be an actuator capable of moving the massage module 170 itself in at least one of the vertical and horizontal directions and the front-back direction. By means of the motion actuator of the massage module, the massage module 170 can move along the rack 111a of the frame portion 110.

[0132] The massage module 170 may also include at least one actuator, and the control unit 120 can control various massage actions by actuating the at least one actuator. For example, the control unit 120 can provide rolling massage, tapping massage, kneading massage, etc., but is not limited to these, by actuating the at least one actuator included in the massage module 170. The at least one actuator included in the massage module can be various actuators such as forward / backward actuators and massage actuators. The forward / backward actuator can cause the massage module 170 to move forward / backward (or tilt) in at least one direction, either forward or backward. The massage actuator can provide various massage actions to the user by causing the massage module 170 to perform various movements.

[0133] The back angle actuator is an actuator that adjusts the angle of the part of the massage device 100 that contacts the user's back. The back angle of the massage device 100 can be adjusted by the movement of the back angle actuator.

[0134] The actuator that moves the armrest frame support is an actuator that adjusts the position of the armrest rest in the massage device 100 for resting the user's arm. The position of the armrest rest (i.e., the position of the arm massage unit 102) can be adjusted by using the actuator that moves the armrest frame support.

[0135] The leg angle actuator is an actuator that adjusts the angle of the leg massage section 103 of the massage device 100. The angle between the leg massage section 103 and the body massage section 101 can be adjusted by the action of the leg angle actuator.

[0136] A foot massage actuator is an actuator that actuates the foot massage module included in the leg massage unit 103. For example, the control unit 120 can provide foot massage to the user by using the foot massage actuator.

[0137] The leg length adjustment actuator is an actuator that adjusts the length of the leg massage unit 103. For example, the control unit 120 can use the leg length adjustment actuator to adjust the length of the leg massage unit 103 to fit the user, so that the user can receive a massage that matches their body shape.

[0138] The sliding actuator enables the massage device 100 to slide. For example, by using the action of the sliding actuator, the upper base frame 112a can move forward and / or backward, and as a result, the body frame 111 connected to the upper base frame 112a can also move forward and / or backward.

[0139] In addition, the above-mentioned... Figure 1The airbag and / or air supply unit are considered components included in the massage module 170, and the control unit 120 can control the operation of the massage device 100 by controlling the airbag and / or air supply unit.

[0140] The storage unit 130 can be implemented by one or more memory units. The storage unit 130 can store various information related to the massage device 100. For example, the information stored in the storage unit 130 may include massage control information and personal authentication information, but is not limited to these. Information related to the user may include personal authentication information, user biometric information (e.g., age, height, weight, blood pressure, body composition, heart rate, electrocardiogram, etc.), and other user-related information.

[0141] The storage unit 130 can be implemented using a non-volatile storage medium capable of continuously storing arbitrary data. For example, the storage unit 130 may include not only disks, optical disks, and magneto-optical storage devices, but also storage devices based on flash memory and / or battery backup memory, but is not limited to these.

[0142] The storage unit 130 is a main storage device directly accessed by the processor, such as random access memory (RAM) like dynamic random access memory (DRAM) or static random access memory (SRAM). It can refer to a volatile storage device whose stored information is instantly deleted when the power is cut off, but is not limited to this. This storage unit 130 can be operated by the control unit 120.

[0143] The user input unit 140 can receive commands related to the motion control of the massage device 100 from the user, and the user input unit 140 can be implemented in various forms.

[0144] The user input unit 140 may have buttons in the form of hotkeys and / or selection buttons for direction selection, cancellation, and input, depending on preset user settings and / or self-preset functions.

[0145] The user input unit 140 can be implemented using a keyboard, dome switch, touchpad (static / electrostatic), rotary dial, momentary switch, etc., but is not limited to these. Alternatively, the user input unit 140 can be based on voice recognition technology to obtain commands based on the user's voice.

[0146] The user input unit 140 may include a display for outputting (or displaying) information about the operation status of the massage device 100 and / or the user's current state. That is, the user input unit 140 may also function as an output unit for outputting information related to the massage device 100. For example, the user input unit 140 may receive user input and send it to the control unit 120. Furthermore, the user input unit 140 may display information related to the massage device 100. For example, various information may be output through the display included in the user input unit 140, such as operation information of at least one of the body massage unit 101, arm massage unit 102, and leg massage unit 103, as well as information related to the operating massage mode.

[0163] Reference Figure 5 According to one embodiment of the present invention, a massage device 400 may include a body massage unit 401 and arm massage units 402 (e.g., a first arm massage unit 402a and a second arm massage unit 402b) disposed on the side of the body massage unit 401. In one embodiment, the massage device 400 may further include a leg massage unit 403 (e.g., a first leg massage unit 403a and a second leg massage unit 403b) disposed on the lower part of the body massage unit 401. In one embodiment, the body massage unit may be configured to massage a part of the user's body. For example, the user may receive a massage of most of the body, such as the upper body and / or thighs, while seated or lying on the body massage unit 401.

[0164] According to one embodiment, a user can receive massage on other parts of the body (e.g., arms or legs) using the arm massage unit 402 or the leg massage unit 403 as needed. For example, the massage device 400 may include massage components (e.g., Figure 12 The arm massage member 491 is disposed in at least one of the body massage section 401, arm massage section 402, and leg massage section 403. The size, shape, number, and placement of the arm massage member 491 may vary depending on the specifications of the massage device 400. In one embodiment, the arm massage member 491 is configured to at least partially move, deform, or align in response to rotation of the forearm section 423 relative to the upper arm section 421.

[0165] According to one embodiment, the arm massage portion 402 may be rotatably coupled to the side portion 411 of the body massage portion 401. In one embodiment, the arm massage portion 402 may include: a first arm massage portion 402a, disposed on one side portion 411 of the body massage portion 401; and a second arm massage portion 402b, disposed on the other side portion 411 of the body massage portion 401. For example, the first arm massage portion 402a may be disposed on one side of the body massage portion 401 to accommodate one side of the user's arm, and the second arm massage portion 402b may be disposed on the other side of the body massage portion 401 to accommodate the other side of the user's arm. In one embodiment, the first arm massage portion 402a and the second arm massage portion 402b may have substantially symmetrical shapes.

[0166] According to one embodiment, the arm massage unit 402 can rotate left and / or right relative to the body massage unit 401 about a first rotation axis A1. Rotation to the left and / or right relative to the body massage unit 401 can be interpreted as adduction and / or abduction of the arm massage unit 402. For example, an action that rotates the arm massage unit 402 toward the front (or inside) of the body massage unit 401 can be called "adduction," and an action that rotates the arm massage unit 402 toward the side (or outside) of the body massage unit 401 can be called "abduction." For example, rotation about the first rotation axis A1 can be understood as the arm massage unit 402 rotating relative to the body massage unit 401 in at least one direction, either inward or outward. As described below, the arm massage unit 402 may include an upper arm portion 421 (or a connecting portion) and a forearm portion 423 (or a rotating portion). The rotation of the arm massage unit 402 around the first rotation axis A1 can be understood as the upper arm portion 421 rotating relative to the body massage unit 401 around the first rotation axis A1.

[0167] According to one embodiment, the arm massage unit 402 can rotate upward and / or downward relative to the body massage unit 401 about a second rotation axis A2. For example, rotation about the second rotation axis A2 can be understood as the arm massage unit 402 rotating relative to the body massage unit 401 in at least one of the upward and downward directions. When the arm massage unit 402 includes an upper arm portion 421 (or a connecting portion) and a forearm portion 423 (or a rotating portion), the rotation of the arm massage unit 402 about the second rotation axis A2 can be understood as the upper arm portion 421 rotating relative to the body massage unit 401 about the second rotation axis A2. For example, the massage device 400 may provide a first rotation axis A1 and a second rotation axis A2. In this case, it can be understood that the arm massage unit 402 and / or the upper arm portion 421 are configured to rotate relative to the body massage unit 401 in at least one of the upward, downward, inward, and outward directions of the body massage unit 401. In one embodiment, when the arm massage unit 402 includes a first arm massage unit 402a and a second arm massage unit 402b, the first arm massage unit 402a and the second arm massage unit 402b may be configured to rotate relative to the body massage unit 401 in at least one of the following directions: the upper direction, the lower direction, the inner direction, and the outer direction, and to rotate in at least one of the following modes: independent of each other, relative to each other, linked, synchronous, non-linked, and asynchronous.

[0168] According to one embodiment, the arm massage unit 402 may include: an upper arm portion 421 disposed on a side portion 411 of the body massage unit 401; and a forearm portion 423, one end of which is rotatably coupled to the upper arm portion 421. For example, the arm massage unit 402 may include a joint structure corresponding to the user's elbow joint. In one embodiment, the upper arm portion 421 may be configured to receive and / or massage the upper arm portion of the user's arm. In one embodiment, the forearm portion 423 may be configured to receive and / or massage the forearm portion of the user's arm. Here, the expression "receive and / or massage the forearm portion" is understood to include the meaning of also receiving or massaging the user's hand.

[0169] According to one embodiment, refer to Figure 12 or Figure 18The massage device 400 and / or the arm massage unit 402 may further include a drive unit 404 located between the upper arm portion 421 and the forearm portion 423. For example, the drive unit 404 is capable of rotatably connecting the upper arm portion 421 and the forearm portion 423. In one embodiment, the drive unit 404 may be understood as providing a third rotation axis A3, and the forearm portion 423 is capable of rotating relative to the upper arm portion 421 about the third rotation axis A3. In one embodiment, rotation relative to the third rotation axis A3 may be understood as the action of rotating the upper arm portion 421 relative to the forearm portion 423. In one embodiment, the action of rotating the forearm portion 423 about the third rotation axis A3 may be understood as the action of rotating relative to the upper arm portion 421 in at least one direction, either inward or outward, towards the body massage unit 401. As described below, in the default state, the arm massage portion 402 (e.g., upper arm portion 421 and forearm portion 423) can be generally aligned side-by-side with the side portion 411 (e.g., side or side plate) of the body massage portion 401, and can be configured such that the forearm portion 423 can rotate from this position in at least one direction (e.g., at least one of the inner and outer directions).

[0170] According to one embodiment, a first rotation axis A1 is disposed in the upper region of the body massage unit 401, and can be understood as an axis (or virtual axis) extending along the width direction (or left-right direction, side direction) of the body massage unit 401. In this case, the first rotation axis A1 can be disposed in the upper region of the body massage unit 401 at a position corresponding to the user's shoulder. In one embodiment, a third rotation axis A3 can be disposed in front of the first rotation axis A1 and / or the second rotation axis A2, and aligned in a direction intersecting the first rotation axis A1 and / or the second rotation axis A2. In one embodiment, as the arm massage unit 402 rotates around the first rotation axis A1 (and / or the second rotation axis A2), the alignment direction of the third rotation axis A3 relative to the first rotation axis A1 and / or the alignment direction of the third rotation axis A3 relative to the second rotation axis A2 may change. In one embodiment, as the arm massage unit 402 rotates around the first rotation axis A1 (and / or the second rotation axis A2), the tilt angle of the third rotation axis A3 relative to the first rotation axis A1 and / or the tilt angle of the third rotation axis A3 relative to the second rotation axis A2 may change.

[0171] According to one embodiment, the leg massage unit 403 may include a first leg massage unit 403a and a second leg massage unit 403b. For example, the first leg massage unit 403a may be disposed at the lower part of the body massage unit 401 and used to accommodate one of the user's legs, and the second leg massage unit 403b may be disposed at the lower part of the body massage unit 401 and used to accommodate the user's other leg. In this case, as... Figure 5 and Figure 11As shown, the first leg massage unit 403a and the second leg massage unit 403b can be physically separate independent structures. In one embodiment, the first leg massage unit 403a and the second leg massage unit 403b may include massage members and massage the user's legs. In one embodiment, the first leg massage unit 403a and the second leg massage unit 403b may be configured to rotate relative to each other in at least one of the following modes: independent, relative, linked, synchronous, non-linked, and asynchronous. For example, the first leg massage unit 403a and the second leg massage unit 403b may be integrated into the lower part of the body massage unit 401 and configured to rotate relative to each other about a fourth rotation axis A4 in at least one of the following modes: independent, relative, linked, synchronous, non-linked, and asynchronous.

[0172] Figures 6 to 11 This is a diagram illustrating the body relaxation function and / or body stretching function of a massage device according to an embodiment of the present invention.

[0173] first, Figures 6 to 9 The arm massage unit 402 is shown, in which the forearm part 423 rotates relative to the upper arm part 421 and / or the body massage unit 401 about the third rotation axis A3, thereby realizing the functions of relaxing and / or stretching the user's body (e.g., the arm), and / or exercising and / or rehabilitating the body. Figure 6 The forearm portion 423 of the first arm massage unit 402a and the forearm portion 423 of the second arm massage unit 402b are shown in an abducted state. Figure 7 It can be shown that with the second arm massage portion 402b (e.g., forearm portion 423) in a default state (e.g., aligned side-by-side with the side portion 411 of the body massage portion 401), the first arm massage portion 402a (e.g., forearm portion 423) is in an adducted state. Based on the default state, the maximum adduction angle of the forearm portion 423 can be greater than its maximum abduction angle. In one embodiment, with the forearm portion 423 of the first arm massage portion 402a in the default state (e.g., as shown in the image), the first arm massage portion 402a (e.g., aligned side-by-side with the side portion 411 of the body massage portion 401) is in an adducted state. Figure 5 As shown, when the arm massage unit 402 is aligned side-by-side with the side portion 411 of the body massage unit 401 and / or placed on the upper end of the side portion 411 of the body massage unit 401, the forearm portion 423 of the second arm massage unit 402b can be adducted. Figure 8 The diagram illustrates a state where the adduction of the forearm portion 423 of the first arm massage portion 402a and the abduction of the forearm portion 423 of the second arm massage portion 402b occur simultaneously. In one embodiment, the adduction of the forearm portion 423 of the second arm massage portion 402b and the abduction of the forearm portion 423 of the first arm massage portion 402a can occur simultaneously. Figure 9It can be shown that the forearm portion 423 of the first arm massage portion 402a and the forearm portion 423 of the second arm massage portion 402b are simultaneously adducted.

[0174] According to one embodiment, the adduction and / or abduction of the forearm portion 423 relative to the upper arm portion 421 can be combined with the up-down and left-right rotation of the upper arm portion 421 relative to the body massage portion 401. For example, the rotation of the forearm portion 423 relative to the upper arm portion 421 can be combined with the rotation of the upper arm portion 421 relative to the body massage portion 401 to achieve relaxation, stretching, movement, and / or rehabilitation functions for the user's body (e.g., the arm). Figure 10 The structure can be shown as a combination of the rotation of the forearm portion 423 relative to the upper arm portion 421 and the rotation of the upper arm portion 421 relative to the body massage portion 401, and / or Figure 11 This can be shown as the upper arm 421 rotating relative to the body massage unit 401. (See reference...) Figure 10 The upper arm portion 421 can rotate upward relative to the body massage portion 401, while the forearm portion 423 adducts relative to the upper arm portion 421. (See reference...) Figure 11 When the arm 423 is in its default state, the upper arm 421 can rotate upward relative to the body massage unit 401. As described above, the rotation of the arm massage unit 402, for example, the rotation of the upper arm 421 relative to the body massage unit 401, and the rotation of the forearm 423 relative to the upper arm 421 can be combined in various ways. In one embodiment, by combining the rotation of the upper arm 421 relative to the body massage unit 401 and the rotation of the forearm 423 relative to the upper arm 421 in various ways, it is possible to simulate arm movements in daily life and / or arm movements in physical activities such as swimming and skipping rope.

[0175] According to one embodiment, the user controller 419 (e.g.) Figure 1 The massage device control device 200 may be configured on the arm massage unit 402. In one embodiment, the user controller 419 may be located in a position other than that shown in the figure, within the range that does not interfere with the rotation of the arm massage unit 402, taking into account the convenience of user operation.

[0176] According to one embodiment, the foot massage unit 403 may include a first foot massage unit 403a and a second foot massage unit 403b that rotate independently of each other about a fourth rotation axis A4 relative to the body massage unit 401. In one embodiment, the rotation of the foot massage unit 403 can be adjusted to allow the user to adopt a desired massage posture by adjusting the alignment of the foot massage unit 403 relative to the body massage unit 401.

[0177] Figure 12This is a first perspective view showing the arm massage portion of a massage device according to an embodiment of the present invention. Figure 13 This is a second perspective view showing the arm massage portion of a massage device according to an embodiment of the present invention. Figure 14 This is a first perspective view showing the upper arm portion (or connecting portion) of the arm massage portion of a massage device according to an embodiment of the present invention. Figure 15 This is a second perspective view showing the upper arm portion (or connecting portion) of the arm massage portion of a massage device according to an embodiment of the present invention. Figure 16 This is a first perspective view showing the forearm portion (or rotating portion) of the arm massage portion of a massage device according to an embodiment of the present invention. Figure 17 This is a second perspective view showing the forearm portion (or rotating portion) of the arm massage portion of a massage device according to an embodiment of the present invention.

[0178] Reference Figures 12 to 17 The arm massage section 402 shown can, for example, be... Figures 5 to 11 Example of the first arm massage portion 402a. The first arm massage portion 402a and the second arm massage portion 402b are substantially symmetrical in shape to each other. For ease of explanation, the ordinal numbers "first" or "second" used to label the arm massage portion 402 in the above embodiments may be omitted. In one embodiment, the arm massage portion 402 may include an upper arm portion 421 and a forearm portion 423 rotatably coupled to the upper arm portion 421. For example, the upper arm portion 421 may serve as a side portion 411 rotatably coupled to the body massage portion 401 and a structural member connecting the forearm portion 423 to the body massage portion 401, which can be understood as a "connecting portion" in one embodiment. For example, the forearm portion 423, one end of which is rotatably coupled to the upper arm portion 421, is rotatable relative to the body massage portion 401 together with the upper arm portion 421 and can rotate relative to the upper arm portion 421. The rotation of the forearm portion 423 and the upper arm portion 421 together relative to the body massage portion 401 can be understood as a rotation (or rotational) motion of the forearm portion 423 centered on the first rotation axis A1 and the second rotation axis A2. In one embodiment, the rotation of the forearm portion 423 relative to the upper arm portion 421 can be understood as a rotation motion of the forearm portion 423 centered on the third rotation axis A3. In one embodiment, this forearm portion 423 can be understood as a "rotating portion".

[0179] According to one embodiment, the upper arm portion 421 may provide a first inner space IS1, and the forearm portion 423 may provide a second inner space IS2. When the forearm portion 423 is attached to the upper arm portion 421, the first inner space IS1 and the second inner space IS2 may be combined to form the inner space IS of the arm massage portion 402. For example, the inner space IS can be understood as a receiving space and / or a massage space. For example, the inner space IS of the arm massage portion 402 may be a space for receiving a part of the user's body, i.e., a space for receiving the arm. In one embodiment, the arm massage portion 402 may include at least one arm massage member 491. For example, the arm massage member 491 may be configured in the inner space IS and align and / or deform in response to rotation of the forearm portion 423 relative to the upper arm portion 421. For example, a portion of the arm massage member 491 is fixed to the upper arm portion 421 and another portion of the arm massage member 491 is fixed to the forearm portion 423, so that the arm massage member 491 can be aligned and / or deformed accordingly with the relative positions of the upper arm portion 421 and the forearm portion 423. In one embodiment, the arm massage member 491 can massage at least a portion of the user's arm by incorporating a built-in tapping actuator, an airbag, a sliding actuator, and / or a heating device.

[0180] According to one embodiment, the massage device 400 and / or the arm massage unit 402 may further include a drive unit 404. For example, when the drive unit 404 is omitted, the forearm portion 423 may rotate relative to the upper arm portion 421 according to the movement of the arm portion accommodated in the inner space IS based on the user's intention. In one embodiment, when the massage device 400 and / or the arm massage unit 402 further includes a drive unit 404, the massage device 400 may relax and / or stretch the user's body (e.g., the arm) by the movement of the drive unit 404, or rotate the forearm portion 423 relative to the upper arm portion 421 by simulating arm movements. The structure of the drive unit 404 will be described with reference to... Figure 19 More detailed explanations will follow.

[0181] According to one embodiment, when the upper arm portion 421 and the forearm portion 423 are connected by a drive portion 404, the arm massage portion 402 may further include a shaft 445e and / or a gear 445d (e.g., Figure 22(Helical gear 445d). In one embodiment, shaft 445e and / or gear 445d may be configured on either upper arm portion 421 or forearm portion 423 and may rotate relative to the other of upper arm portion 421 and forearm portion 423. In the illustrated embodiment, although shaft 445e and / or gear 445d are illustrated as being configured on the lower portion of forearm portion 423, it should be understood that embodiments of the present invention are not limited thereto. For example, additional drive units (e.g., shaft 445e and / or gear 445d) not shown may be configured on the upper portion of forearm portion 423. In one embodiment, when configured on the upper portion of forearm portion 423, drive units below forearm portion 423 (e.g., shaft 445e and / or gear 445d) may be configured on the lower portion of forearm portion 423. Figure 16 The shaft 445e and / or gear 445d may be omitted. In one embodiment, when the shaft 445e and / or gear 445d are configured on the lower part of the forearm portion 423, a rotary disk (not shown) may be provided on the upper part of the forearm portion 423 so that the drive unit 404 is rotatably coupled to the upper arm portion 421 together with the forearm portion 423. In one embodiment, the shaft 445e and / or gear 445d (e.g., Figure 22 or Figure 23 The helical gear 445d can be understood as part of the drive unit 404.

[0182] According to one embodiment, shaft 445e can be fixed to either the upper arm portion 421 or the forearm portion 423, and rotatably configured to the other of the upper arm portion 421 and the forearm portion 423. In the illustrated embodiment, shaft 445e can be understood as being fixed to the forearm portion 423 and aligned with the third rotation axis A3. In one embodiment, shaft 445e can be mounted via an assembly ring (e.g., Figure 22 or Figure 23 The assembly ring 449c) and / or shaft fixing components (e.g. Figure 22 or Figure 23 The shaft fixing member 449e is fixed to the forearm portion 423. Regarding the fixing structure of the shaft 445e, please refer to... Figures 22 to 25 Further explanation is needed.

[0183] According to one embodiment, gear 445d can be at least one of a spur gear, a pinion, and a helical gear. For example, the type or number of gears 445d can be appropriately combined considering the direction or path of power transmission in the drive unit 404. In one embodiment, gear 445d can be fixed to shaft 445e. For example, gear 445d can be fixed to either the upper arm portion 421 or the forearm portion 423, and can rotate together with shaft 445e relative to the other of the upper arm portion 421 and forearm portion 423. The configuration, rotation structure, and power transmission structure of gear 445d will be described with reference to... Figure 22 and Figure 23 Further explanation is needed.

[0184] According to one embodiment, the massage device 400 and / or the arm massage unit 402 may further include a guide portion 447. In a structure in which the upper arm portion 421 and the forearm portion 423 are rotatably coupled using a shaft 445e, for example, the guide portion 447 can stabilize the relative rotational movement between the upper arm portion 421 and the forearm portion 423. In one embodiment, the guide portion 447 may be fixed together with the shaft 445e and / or the gear 445d to either the upper arm portion 421 or the forearm portion 423. In one embodiment, when the shaft 445e and / or the gear 445d is fixed to either the upper arm portion 421 or the forearm portion 423, the guide portion 447 may be disposed together with the shaft 445e and / or the gear 445d on the other of the upper arm portion 421 and the forearm portion 423. In one embodiment, while fixed to either the upper arm portion 421 or the forearm portion 423, the guide portion 447 can be supported on an opposing object (e.g., the other of the upper arm portion 421 and forearm portion 423 and / or...). Figure 23 (The upper end cap). For example, when the upper arm portion 421 and the forearm portion 423 rotate relative to each other, the guide portion 447 may contact and / or rub against the opposing object to support the opposing object (or the other of the upper arm portion 421 and the forearm portion 423) or be supported by the opposing object. For example, in an embodiment where the guide portion 447 is disposed on the forearm portion 423, the guide portion 447 may contact and / or be supported by the upper arm portion 421 and / or other structural members fixed to the upper arm portion 421, thereby suppressing further displacement of the upper arm portion 421 and the forearm portion 423 during rotational motion.

[0185] According to one embodiment, when the upper arm portion 421 and the forearm portion 423 rotate relative to each other, the guide portion 447 can follow a curved trajectory on the relative object (e.g., Figure 23 The guide portion 447 moves on the upper end cap. In one embodiment, the curved trajectory of the guide portion 447 may be an arc trajectory centered on axis 445e. In one embodiment, the guide portion 447 may include at least one plunger. The at least one plunger may suppress displacement other than rotational movement during relative rotation of the upper arm portion 421 and the forearm portion 423. For example, the guide portion 447 may stabilize the relative rotational movement of the upper arm portion 421 and the forearm portion 423. In one embodiment, the guide portion 447 may include multiple plungers. When multiple plungers are configured, adjacent two plungers may be configured at a specified angular interval along a circumferential direction centered on axis 445e and / or the third rotation axis A3. In one embodiment, multiple plungers may be configured at equal angular intervals along a circumferential direction centered on axis 445e and / or the third rotation axis A3.

[0186] Figure 18 This is a diagram illustrating the rotation of the forearm portion in the arm massage section of a massage device according to an embodiment of the present invention.

[0187] Reference Figure 18 The forearm portion 423 can rotate relative to the upper arm portion 421. Figure 18 In the diagram, the position indicated by "P1" represents the position of the forearm portion 423 in the default state. As mentioned earlier, "default state" can be understood as a state in which the arm massage portion 402 is substantially parallel and aligned with the side portion 411 (e.g., side or side plate) of the body massage portion 401. However, it should be noted that while the "state in which the arm massage portion 402 is substantially parallel and aligned with the side portion 411 of the body massage portion 401" is defined as the default state in the description of embodiments of the present invention, this is only for illustrative purposes and is not intended to limit the embodiments of the present invention. For example, the default state can be defined as the state in which the arm massage portion 402 is aligned to a position and / or shape corresponding to the posture of a user sitting in the massage device 400 and in a relaxed state. In this case, either the upper arm portion 421 or the forearm portion 423 may not be parallel to the side portion 411 of the body massage portion 401. In one embodiment, the default state may refer to the state where the upper arm portion 421 and the forearm portion 423 are aligned in the same direction. This can be that the length direction of the upper arm portion 421 and the length direction of the forearm portion 423 are both aligned with the same virtual axis (e.g., Figure 12 , Figure 13 and / or Figure 18 The alignment state (indicated by the axis "VA"). For example, when one end of the forearm 423 is attached to the upper arm 421 and the alignment is in the default state, it can be understood that the virtual axis aligned along the length direction of the upper arm 421 passes through one end of the forearm 423 and the other end of the forearm 423 for alignment.

[0188] According to one embodiment, Figure 18 In this context, the position indicated by "P2" represents the position of the forearm portion 423 when it is in an adducted state. In one embodiment, the position indicated by "P2" represents the state of the forearm portion 423 when it is rotated inward at its maximum angle from the default state. Figure 18In this context, the position indicated by "P3" represents the position of the forearm portion 423 in an abducted state. In one embodiment, the position indicated by "P3" represents the state of the forearm portion 423 when it rotates outward at its maximum angle from its default state. In one embodiment, the maximum adduction angle may be greater than the maximum abduction angle. For example, when the range of rotation of the forearm portion from its default position relative to the upper arm relative to the inward direction is defined as a first angle range, and the range of rotation of the forearm portion from its default position relative to the upper arm relative to the outward direction is defined as a second angle range, the first angle range may be greater than the second angle range. In one embodiment, the adduction and / or abduction of the forearm portion 423 can be achieved by the user's movement (or external force), or by the action of the drive unit 404 according to the user's needs. In other words, the forearm portion 423 can automatically perform adduction and / or abduction movements (or can rotate to one side and / or the other side of the forearm portion 423) under the control of the control unit 120 according to the action of the drive unit 404, and can also be manually performed adduction and / or abduction movements under the action of external force. Here, "manually performing adduction and / or abduction" can refer to the action of the upper arm 421 and forearm 423 rotating relative to each other in response to the user's arm movements. In one embodiment, the massage device 400 can automatically perform adduction / abduction of the forearm 423 relative to the upper arm 421 by including a drive unit 404 (e.g., a drive actuator 443 and / or a power transmission unit). Regarding this structure, see [reference needed]. Figure 19 Please provide further explanation.

[0189] Figure 19 This is a diagram illustrating the drive unit in the arm massage section of a massage device according to an embodiment of the present invention. Figure 20 This is a diagram illustrating the internal structure of the drive unit in the arm massage section of a massage device according to an embodiment of the present invention. Figure 21 This is a diagram illustrating the fixing cover of the drive unit in the arm massage section of a massage device according to an embodiment of the present invention.

[0190] Reference Figures 19 to 21 The drive unit 404 may include a drive actuator 443 and a power transmission unit. For example, the power transmission unit may include at least one timing pulley and / or at least one gear. In one embodiment, when shaft 445e and / or gear (e.g. Figure 22When the helical gear 445d is disposed on either the upper arm portion 421 or the forearm portion 423, it can be interpreted that the drive unit 404 and / or the power transmission unit includes the shaft 445e and / or the gear 445d. In one embodiment, when the drive actuator 443 is disposed on either the upper arm portion 421 or the forearm portion 423, the shaft 445e (and / or the helical gear 445d) may be disposed on the other of the upper arm portion 421 and the forearm portion 423. In one embodiment, the power transmission unit may rotate the shaft 445e (and / or the helical gear 445d) according to the action of the drive actuator 443. For example, the power transmission unit may rotate the forearm portion 423 relative to the upper arm portion 421, or rotate the upper arm portion 421 relative to the forearm portion 423, based on the action of the drive actuator 443.

[0191] According to one embodiment, the drive unit 404 may include a retaining cover 441a. For example, the retaining cover 441a may provide space for accommodating the drive actuator 443, the power transmission unit, the shaft 445e, and / or the helical gear 445d. For example, the retaining cover 441a may provide a first space SP1 for accommodating the drive actuator 443 and a second space SP2 for accommodating a portion of the shaft 445e and / or the helical gear 445d. In one embodiment, depending on the structure of the power transmission unit, a clearance groove 441d may also be provided on the outer surface of the retaining cover 441a. For example, the clearance groove 441d may be used as space for arranging spur gears 445a, 445b. In the illustrated embodiment, the retaining cover 441a has a shape that takes into account the combination of the drive actuator 443, multiple spur gears 445a, 445b, worm gear 445c, and helical gear 445d. It should be noted that embodiments of the present invention are not limited to this shape. For example, referring to… Figure 24 It can be seen that when the power transmission part includes a synchronous belt (e.g.) Figure 24 When the structure of the timing belt 545c is used, the retaining cover 441a can be modified to provide for accommodating the drive actuator 443 and multiple timing pulleys (e.g., Figure 24 The shape of the synchronous pulleys 545a and 545b and the space of the synchronous belt.

[0192] According to one embodiment, the drive unit 404 and / or the power transmission unit may further include spur gears 445a and 445b disposed in the clearance groove 441d and a worm gear 445c disposed between the first space SP1 and the second space SP2. The first spur gear 445a of the spur gears 445a and 445b can be rotated by the drive actuator 443, and the second spur gear 445b of the spur gears 445a and 445b can mesh with the first spur gear 445a. For example, the actuation and / or rotational force of the drive actuator 443 can be transmitted through the first spur gear 445a and the second spur gear 445b. In one embodiment, the worm gear 445c may be configured to rotate together with the second spur gear 445b. The helical gear 445d disposed in the second space SP2 meshes with the worm gear 445c, so that the power of the drive actuator 443 is transmitted through the spur gears 445a and 445b and the worm gear 445c, thereby causing the helical gear 445d to rotate. For example, the driving force generated by the operation of the drive unit 404 (e.g., the drive actuator 443) can realize the rotational movement of the forearm part 423 relative to the upper arm part 421 and / or the rotational movement of the upper arm part 421 relative to the forearm part 423.

[0193] According to one embodiment, the drive unit 404 may further include an upper end cover 441b. For example, the upper end cover 441b may be combined with a fixed cover 441a. In one embodiment, the upper end cover 441b and the fixed cover 441a may be understood as constituting a housing and / or casing of the drive unit 404. In one embodiment, the upper end cover 441b and / or the fixed cover 441a may be disposed on and / or combined with either the upper arm portion 421 or the forearm portion 423. When the upper end cover 441b and / or the fixed cover 441a are disposed on either the upper arm portion 421 or the forearm portion 423, the shaft 445e and / or the helical gear 445d are disposed on the other of the upper arm portion 421 and the forearm portion 423, and are at least partially received in the second space SP2 of the fixed cover 441a via the upper end cover 441b. Further reference will be made to the structure connecting the upper arm portion 421 and the forearm portion 423 via the drive unit 404. Figure 22 and Figure 23 Please provide an explanation.

[0194] Figure 22 and Figure 23 This is a diagram illustrating the structure of the drive unit of a massage device according to an embodiment of the present invention, which connects the upper arm portion 421 and the forearm portion 423.

[0195] Reference Figure 22 and Figure 23When shaft 445e is fixed to forearm portion 423, upper end cover 441b and / or fixing cover 441a can be fixed to upper arm portion 421. However, as mentioned above, according to the embodiment, shaft 445e can be fixed to upper arm portion 421, and upper end cover 441b and / or fixing cover 441a can be fixed to forearm portion 423. In one embodiment, when shaft 445e is fixed to forearm portion 423, shaft 445e and / or helical gear 445d can be rotatably accommodated in the fixing cover 441a of drive portion 404.

[0196] According to one embodiment, the rotation of shaft 445e and / or helical gear 445d inside the fixed cover 441a can be... Figure 5 or Figure 18 The rotation is centered on the third rotation axis A3. In one embodiment, as described above, when the shaft 445e is fixed to the forearm portion 423, the fixing cover 441a, the upper end cover 441b, and / or the drive actuator 443 may be configured and / or fixed to the upper arm portion 421. However, the embodiments of the present invention are not limited to this, and embodiments in which the shaft 445e is configured to be on the upper arm portion 421 and the drive actuator 443 is configured to be on the forearm portion 423 may also be implemented.

[0197] According to one embodiment, the helical gear 445d can mesh with the worm gear 445c inside the fixed cover 441a. For example, when the drive actuator 443 is running, the first spur gear 445a, the second spur gear 445b, the worm gear 445c, and the helical gear 445d rotate to transmit the driving force of the drive actuator 443, thereby allowing the shaft 445e and / or the forearm portion 423 to rotate about the third rotation axis A3. In one embodiment, the spur gears 445a and 445b can be omitted, and the drive actuator 443 can be configured to directly rotate the worm gear 445c. For example, the worm gear 445c can be disposed on the output shaft of the drive actuator 443 without passing through the spur gears 445a and 445b. In one embodiment, the worm gear 445c meshes with the helical gear 445d, thereby functioning as a power transmission part that transmits the driving force of the drive actuator 443 to the helical gear 445d and / or the forearm portion. In one embodiment, the statement "the forearm portion 423 rotates about the third rotation axis A3" may refer to the forearm portion 423 adducting and / or abducting relative to the upper arm portion 421.

[0198] According to one embodiment, when the drive unit 404 rotatably connects and / or engages the upper arm portion 421 with the forearm portion 423, the guide portion 447 may contact and / or be supported by the upper end cap 441b. In one embodiment, as the forearm portion 423 and / or the shaft 445e rotates relative to the upper arm portion 421 (or relative to the upper end cap 441b), the guide portion 447 may rub against the upper end cap 441b while moving along a curved trajectory on the upper end cap 441b. In one embodiment, the trajectory of the guide portion 447 moving on the upper end cap 441b may be an arcuate trajectory centered on the shaft 445e (or the third rotation axis A3). In one embodiment, the guide portion 447 may include at least one plunger arranged along the movement trajectory on the upper end cap 441b. For example, one or more plungers may be fixed to the forearm portion 423 and supported by the upper end cap 441b, thereby maintaining a constant and / or uniform gap between the upper end cap 441b and the forearm portion 423. For example, by configuring the guide portion 447, the rotation of the forearm portion 423 relative to the upper arm portion 421 and / or the upper end cap 441b can be stabilized.

[0199] According to one embodiment, the arm massage unit 402 and / or drive unit 404 may include a bearing 449a, support plates 449b, 449d, a mounting ring 449c, and / or a shaft fixing member 449e. In one embodiment, the bearing 449a, support plates 449b, 449d, mounting ring 449c, and / or shaft fixing member 449e can securely fix the shaft 445e to the upper arm and / or forearm. In one embodiment, the bearing 449a, support plates 449b, 449d, mounting ring 449c, and / or shaft fixing member 449e can support the shaft 445e so that it rotates stably within the fixing cover 441a. For example, by means of the inside of the fixing cover 441a (e.g. Figure 21 A receiving groove 441c is configured with a bearing 449a and / or a first support plate 449b to support one end of a shaft 445e. The shaft 445e is engaged with a retaining cover 441a via the bearing 449a and is rotatable relative to the retaining cover 441a. In one embodiment, the first support plate 449b engages with the bottom of the retaining cover 441a from within the receiving groove 441c, thereby constraining and / or securing the bearing 449a. In one embodiment, the first support plate 449b can be understood as a plate extending from the outer ring of the bearing 449a. For example, according to an embodiment, the first support plate 449b may be part of the bearing 449a.

[0200] According to one embodiment, the mounting ring 449c and / or the shaft fixing member 449e can secure the shaft 445e to the forearm portion 423 (or upper arm portion 421). For example, the mounting ring 449c, as a structural member disposed inside the forearm portion 423 to support the shaft 445e, can be implemented in one embodiment as a boss protruding from the inner side of the forearm portion 423. In one embodiment, when the mounting ring 449c is manufactured as a component independent of the forearm portion 423, a second support plate 449d can be provided to securely fix the mounting ring 449c to the inner side of the forearm portion 423. In one embodiment, the shaft fixing member 449e can be used when the shaft 445e is joined and / or fixed to other structural members of the forearm portion 423 (or upper arm portion 421). The shaft fixing member 449e may include a structural member penetrating inside the forearm portion 423 (or upper arm portion 421) and a screw fastened to the shaft 445e.

[0201] According to one embodiment, although not shown, when the shaft 445e rotates together with the forearm portion 423 (or upper arm portion 421), the shaft 445e may include a D-shaped cut plane on its outer peripheral surface. The cross-section of the shaft 445e is generally circular, but in the section where the D-shaped cut plane is applied, the cross-section of the shaft 445e may include a straight portion. In one embodiment, by providing a planar (or straight) section on the forearm portion 423 (or upper arm portion 421) corresponding to the D-shaped cut plane of the shaft 445e, the shaft 445e can be substantially fixed to the forearm portion 423 (or upper arm portion 421) and / or the mounting ring 449c in the rotational direction centered on the third rotational axis A3. When the shaft 445e is fixed to the forearm portion 423 (or upper arm portion 421) in the rotational direction centered on the third rotational axis A3, a portion of the shaft 445e may have a polygonal cross-sectional shape.

[0202] Figure 24 This is a diagram illustrating another example of the drive unit of a massage device according to an embodiment of the present invention. Figure 24 When referring to the driving unit, for structures that can be easily understood by referring to prior embodiments, the same reference numerals as those in prior embodiments may be given or omitted, and their detailed descriptions may also be omitted. For in Figure 24 Structures omitted in the description of the embodiments can be found in the detailed description of the prior embodiments.

[0203] Figure 24 A drive unit 504 (e.g., a power transmission unit) including timing pulleys 545a, 545b and / or timing belt 545c may be shown. For example, when... Figure 22 or Figure 23 When the drive unit 404 is defined as a structure that transmits power through a gear combination, Figure 24The drive unit 504 can be understood as having a structure that transmits power using a timing belt 545c. In one embodiment, a first timing pulley 545a, provided as part of the power transmission unit, is configured to rotate via a drive actuator 443, and Figure 22 The helical gear 445d can be replaced by a second synchronous pulley 545b. For example, the second synchronous pulley 545b can be substantially fixed to the shaft 445e, while being connected to the first synchronous pulley 545a via a synchronous belt 545c. In one embodiment, the second synchronous pulley 545b can be part of the shaft 445e. For example, it can be understood that the first synchronous pulley 545a is connected to the shaft 445e via a synchronous belt 545c. In one embodiment, when defined Figure 22 When the drive actuator 443 and the shaft 445e in the drive unit 404 are aligned in a direction that intersects each other, it can be understood that, in Figure 24 In the drive unit 504, the drive actuator 443 and the shaft 445e are aligned at an angle of less than 10 degrees to each other and / or are substantially parallel to each other. For example, the drive units 404, 504 and / or the power transmission units can be modified in various ways depending on the relative alignment structure of the drive actuator 443 and the shaft 445e.

[0204] Figure 25 This is a diagram illustrating the structure of the massage device's central shaft assembled in the forearm portion according to an embodiment of the present invention. (Refer to...) Figure 25 The arm massage portion 402 and / or shaft 445e may include a flange 647a extending from one end of shaft 445e. Figure 25 In the side view, the flange 647a is flat plate-shaped, but may have a curved surface corresponding to the shape of the engagement portion of the forearm portion 423 (or upper arm portion 421). In one embodiment, the shaft 445e can be engaged to the forearm portion 423 (or upper arm portion 421) via the flange 647a. For example, the flange 647a can be engaged to the forearm portion 423 (or upper arm portion 421) using a bolt and nut combination fastening member. In one embodiment, the guide portion 447 can function as a fastening member for engaging the shaft 445e and / or the flange 647a to the forearm portion 423 (or upper arm portion 421). For example, the guide portion 447 can pass through the flange 647a and engage to the forearm portion 423 (or upper arm portion 421), thereby securing the shaft 445e to the forearm portion 423 (or upper arm portion 421). In one embodiment, to more securely fix the guide portion 447 to the forearm portion 423 (or upper arm portion 421), a fastening boss 647b may be provided inside the forearm portion 423 (or upper arm portion 421). In another embodiment, the fastening boss 647b is omitted and a nut (not shown) is provided to fasten the guide portion 447 inside the forearm portion 423 (or upper arm portion 421).

[0205] exist Figure 25 The embodiment shown illustrates a structure in which shaft 445e is fixed to forearm portion 423, but it should be noted that the embodiments of this utility model are not limited thereto.

[0206] For example, when the forearm portion 423 is a structure that rotates automatically and / or manually relative to the upper arm portion 421, the shaft 445e can be fixed to either the upper arm portion 421 or the forearm portion 423, while being rotatably coupled to the other one that is different from either the upper arm portion 421 or the forearm portion 423.

[0207] In one embodiment, shaft 445e may be fixed to upper arm portion 421 and rotatably coupled to forearm portion 423 (or helical gear 445d). For example, shaft 445e may be disposed in the region of upper arm portion 421 opposite to forearm portion 423. In this case, shaft 445e of upper arm portion 421 may be formed in upper arm portion 421 in a form that protrudes toward forearm portion 423. Furthermore, forearm portion 423 may include a hole formed in the region of forearm portion 423 opposite to shaft 445e.

[0208] Thus, the upper arm portion 421 and the forearm portion 423 can be connected (or combined) to each other by inserting the shaft 445e of the upper arm portion 421 into the hole of the forearm portion 423. The shaft 445e can be fixedly disposed on the upper arm portion 421 and rotatably combined with the forearm portion 423.

[0209] In one embodiment, the shaft 445e can be fixed to the forearm portion 423 and rotatably coupled to the upper arm portion 421. For example, the shaft 445e can be disposed in the region of the forearm portion 423 opposite to the upper arm portion 421. In this case, the shaft 445e of the forearm portion 423 can be formed in the forearm portion 423 in a form that protrudes toward the upper arm portion 421. Furthermore, the upper arm portion 421 may include a hole formed in the region of the upper arm portion 421 opposite to the shaft 445e.

[0210] Thus, the upper arm portion 421 and the forearm portion 423 can be connected (or combined) to each other by inserting the shaft 445e of the forearm portion 423 into the hole of the upper arm portion 421. The shaft 445e can be fixedly disposed on the forearm portion 423 and rotatably combined with the upper arm portion 421.

[0211] As described above, when the forearm portion 423 is a structure that rotates relative to the upper arm portion 421 in an automatic and / or manual manner, the shaft 445e may be disposed in at least one of the upper arm portion 421 and the forearm portion 423, and the hole that engages with the shaft 445e may be disposed in the other.

[0212] In one embodiment, such as Figure 17 As shown, shaft 445e and hole can correspond to the third rotating shaft A3, and are... Figure 17Based on this, it is disposed on at least one side of the upper arm portion 421 and the lower side of the forearm portion 423.

[0213] In one embodiment, in a structure provided with drive units 404 and 504, for example, in a structure in which the forearm portion 423 rotates automatically relative to the upper arm portion 421, the drive units 404 and 504 may be configured such that any part of them is connected to the upper arm portion 421 and another part is connected to the forearm portion 423, thereby causing the forearm portion 423 to rotate relative to the upper arm portion 421 with respect to the axis 445e.

[0214] For example, when the shaft 445e is fixed to either the upper arm portion 421 or the forearm portion 423 and rotatably coupled to another portion different from either the upper arm portion 421 or the forearm portion 423, the drive units 404 and 504 can be fixedly connected to at least one of the frame, inner housing, and outer housing to which the shaft 445e is fixed and rotatably connected to the other portion to which the shaft 445e is rotatably coupled.

[0215] Specifically, when one part of the drive unit 404 or 504 is a drive actuator 443 and the other part is a power transmission unit such as a helical gear 445d, the drive actuator 443 can be fixedly connected (or coupled, configured) to the upper arm part 421 or the forearm part 423, and the helical gear 445d can be rotatably connected (or coupled, configured) to at least one of the frame of the forearm part 423, the inner housing of the forearm part 423, and the outer housing. As described above, the drive actuator 443 of the drive unit 404 or 504 can be fixedly connected to the forearm part 423, and the helical gear 445d can be rotatably connected to the upper arm part 421.

[0216] The technical concept of this utility model has been described above with reference to the accompanying drawings. However, this is only an exemplary description of the preferred embodiment of this utility model and does not limit the scope of this utility model. Furthermore, those skilled in the art should understand that various modifications and imitations can be made without departing from the technical concept of this utility model.

[0217] Furthermore, the structure and function of the massage device described in this manual can be extended and applied to various (wearable) health care devices that provide health care functions (e.g., massage function, biosignal measurement function, etc.). Therefore, the term "massage device" in this manual can be replaced with "(wearable) health care device" for further explanation.
