[0180] As described above, the guide rod (11360) is configured to be inserted into the second rail (31340) of the calf massage frame (21310) when the foot massage frame (11320) is raised. Accordingly, the insertion groove (31342) may be configured in a shape into which both the first guide rod (11330) and the second guide rod (21360) can be inserted.

[0181] Fig. 17 is a one-sided perspective view of a massage unit according to an embodiment of the present invention.

[0182] As illustrated in FIG. 17, according to an embodiment of the present invention, the main frame (31300) may include a plate portion (31350). The plate portion (31350) may be arranged to surround the first rail (31320). As in the illustrated embodiment, when a pair of first rails (31320) are included, the plate portion (31350) may be arranged to extend between the pair of first rails (31320). In one embodiment, the plate portion (31350) may be formed integrally with the main frame (31300). In another embodiment, the plate portion (31350) may be formed separately from the main frame (31300), but may also be coupled to the main frame (31300). The plate portion (31350) may support and position components such as the lead screw bracket (31330) described above.

[0183] The plate portion (31350) may include a hole (31352). In one embodiment, the hole (31352) may include a curved surface. The hole (31352) may pass components such as wiring and an air hose of the leg massage unit (1300). For example, if the leg massage unit (1300) provides massage through an air bag, the air hose may be connected to the leg massage unit (1300).

[0184] According to an embodiment of the present invention, the hole (31352) may be an elongated hole including a short side and a long side longer than the short side. In one embodiment, the elongated hole may be arranged such that the long side of the elongated hole is generally aligned with the vertical direction of the plate portion (31350). In particular, the elongated hole may prevent tangling of wires or hoses, etc., when the foot massage unit (11300) and the calf massage unit (21300) move up and down.

[0185] According to an embodiment of the present invention, a buffer member (31354) may be arranged around the periphery of the hole (31352). As a non-limiting example, the buffer member (31354) may be formed of silicone or rubber. In one example, the buffer member (31354) may be integrally formed around the periphery of the hole (31352). In another example, the buffer member (31354) may be attached to the periphery of the hole (31352). The buffer member (31354) may prevent wiring, air hoses, and the like passing through the hole (31352) from being repeatedly damaged by contact with the hole (31352). When the calf massage unit (21300) is raised, the calf massage unit (21300) may be raised higher than the main frame (31300). At this time, the hole (31352) provides a space in which the wiring, air hose, etc. connected to the calf massage unit (21300) can move upward together with the calf massage frame (21310), thereby preventing the wiring, air hose, etc. from becoming tangled.

[0186] According to an embodiment of the present invention, the sensor unit (1410) may include one or more position sensors. In one embodiment, the position sensors may be disposed on the main frame (31300). For example, the position sensors may be disposed on the plate portion (31350) of the main frame (31300). The position sensors are configured to detect the position of the foot massage unit (11300) or the calf massage unit (21300). The position sensors are configured to transmit the detected information to the control unit (1400).

[0187] The control unit (1400) is configured to control the operation of the leg massage unit (1300). In one embodiment, the control unit (1400) is configured to control the operation of the motor (21320). In one embodiment, the control unit (1400) is configured to control the operation of the actuator (11310).

[0188] Specifically, the control unit (1400) is configured to control the operating timing, operating period, etc. of the motor (21320) or the actuator (11310). When the control unit (1400) receives an operation request of the leg massage unit (1300) by the massage device control device (2000), the control unit (1400) can control the operation of the motor (21320) or the actuator (11310). In one implementation example, when there is a request for raising the leg massage unit (1300) by the user, the control unit (1400) is configured to first raise the calf massage unit (21300) and then raise the foot massage unit (11300). The calf massage unit (21300) is configured to rise from a preset original position and then descend back to the original position, so that the calf massage unit (21300) can be configured to rise first in response to a request to rise so that there is no interference between the foot massage unit (11300) and the calf massage unit (21300).

[0189] Additionally, the control unit (1400) is configured to monitor information detected by the position sensor. The control unit (1400) can monitor and control the positions of the foot massage unit (11300) and the calf massage unit (21300) so that the foot massage unit (11300) and the calf massage unit (21300) do not interfere with each other.

[0190] Fig. 18 illustrates the driving range of the foot massage unit of the leg massage unit according to an embodiment of the present invention, and Fig. 19 illustrates the driving range of the calf massage unit of the leg massage unit according to an embodiment of the present invention.

[0191] As illustrated in FIG. 18, according to the present invention, the driving range of the foot massage unit (11300) can be increased. The foot massage unit (11300) in the center of FIG. 18 is in its original position, the left side of FIG. 18 shows the foot massage unit (11300) in its maximum raised state, and the right side of FIG. 18 shows the foot massage unit (11300) in its maximum lowered state. The foot massage unit (11300) can rise by Z1 from the original position to the maximum raised position with respect to the reference line (O) as the center, and the foot massage unit (11300) can descend by Z2 from the original position to the maximum lowered position with respect to the reference line (O). Z1 and Z2 may vary depending on design conditions, but according to an embodiment of the present invention, Z1 is 70 millimeters (mm), Z2 is 170 mm, and a total driving range of 240 mm can be implemented. In conventional leg massage units, the foot massage unit could only be lowered, and the operating range was also limited to 170 mm, which is lower than that of the present invention. That is, the foot massage unit (11300) according to the present invention can provide an expanded operating range of the foot massage unit (11300), thereby allowing the user to receive a massage of the entire foot regardless of the user's physical condition.

[0192] Referring to FIG. 19, according to the present invention, the calf massage unit (21300) can be driven independently from the foot massage unit (11300), thereby providing the user with various massages or an expanded massage range. In the illustrated embodiment, the calf massage unit (21300) is configured to rise to a preset height Z4 rather than descending (Z3=0) around the reference line (O). That is, the calf massage unit (21300) can rise from the original position of the reference line (O) beyond the hinge axis (1302) by the height of Z4, and then descend back to the original position of the reference line (O). In the past, the foot massage unit and the calf massage unit moved together, making it difficult for tall users to receive a calf massage. However, according to the present invention, the calf massage unit (21300) can move a preset distance around the reference line (O), thereby allowing tall users to receive a calf massage, thereby expanding the massage range.

[0193] While the technical concepts of the present invention have been described above, along with the accompanying drawings, this merely exemplifies preferred embodiments of the invention and does not limit the scope of the invention. Furthermore, it is readily apparent that anyone skilled in the art will be able to make various modifications and imitations without departing from the scope of the technical concepts of the present invention.

[0194] Furthermore, the massage device configuration and functions of this specification can be extended and applied to various (wearable) healthcare devices that can provide healthcare functions (e.g., massage / massage functions, bio-signal measurement functions, etc.). Accordingly, it goes without saying that the "massage device" of this specification can be replaced with the term "(wearable) healthcare device."
