[0002] Massage refers to a medical adjunct therapy that involves applying various forms of mechanical stimulation to specific parts of the body, such as kneading, pressing, stretching, patting, or inducing physical activity, to adjust changes in the body, promote blood circulation, and relieve fatigue.

[0003] Due to economic and time constraints, there is an increasing demand for massage devices or equipment that provide manual massage functions. Specifically, as the need to relieve stiff muscles and eliminate fatigue or stress through massage increases, a variety of massage devices that offer good time and cost-effectiveness have been introduced.

[0004] Recently, with increasing public focus on health, massage devices have evolved from simply providing massage functions to offering a variety of additional and / or medical features. Consequently, research into methods for effectively controlling massage devices has been ongoing, and systems that utilize sensors to detect user status and provide appropriate massage are emerging. In particular, for leg massage devices, sensors that detect the state or position of the user's legs play a crucial role, improving the accuracy of the massage and the user experience.

[0005] However, in existing technologies, the sensor assembly structure is often not exposed internally, leading to reduced sensor response speed or difficulty in accurately detecting the user's state. This type of sensor structure reduces the performance of the massage device and makes it difficult to provide customized massage.

[0006] To address these issues in the prior art, this invention is researching a leg massage sensor structure that can improve the sensor's response speed and enhance user detection performance by exposing the sensor and surface-treating it with polyurethane. Utility Model Content

[0089] A rack may be provided along the length of the upper frame 1131. The rack is a component used to guide the massage module 1110 to move up and down, and can be constructed using known racks that include multiple valleys and multiple ridges.

[0090] According to one embodiment of the present invention, the racks can be arranged facing each other on both sides of the upper frame 1131, and the massage module 1110 can move along the racks.

[0091] The rack is formed in the vertical direction, but is not limited thereto. The rack may include racks in the front-back direction and racks in the vertical direction. In this disclosure, the front-back direction may refer to the direction from the massage module 1110 toward the user or the direction from the user toward the massage module 1110, to... Figure 2 Using the X-axis as a reference, it can refer to the X-axis direction.

[0092] The massage module 1110 may include gears that mesh with a rack. More specifically, the massage module 1110 may include gears that mesh with a rack in the forward-backward direction and a rack in the up-down direction, respectively. The gears are rotated by an actuator disposed in the massage module 1110, thereby allowing the massage module 1110 to move forward, backward, up, or down.

[0093] As the massage module 1110 moves forward, the massage intensity can be increased. Conversely, as the massage module 1110 moves backward, the massage intensity can be decreased.

[0094] Racks can be made of metal or plastic materials. For example, racks can be made of iron, steel, alloys, reinforced plastics, melamine resin, phenolic resin, etc., but are not limited to these.

[0095] The upper frame 1131 can be implemented in various shapes. For example, depending on the shape, the upper frame 1131 can be divided into an S-frame, an L-frame, an S&L-frame, and a double S&L-frame, but is not limited to these.

[0098] The upper frame 1132a of the base can support the upper frame 1131, and the lower frame 1132b of the base can contact the ground. In addition, the upper frame 1132a of the base can be configured to contact the lower frame 1132b of the base.

[0099] According to one embodiment of the present invention, the upper frame 1132a of the base can move along the lower frame 1132b of the base. For example, the upper frame 1132a of the base can slide forward or backward along the lower frame 1132b of the base. In this case, the upper frame 1131 is connected to the upper frame 1132a of the base, so that it can move as the upper frame 1132a of the base moves.

[0100] For example, when the upper frame 1132a of the base moves forward, the upper frame 1131 can also move forward together; when the upper frame 1132a of the base moves backward, the upper frame 1131 can also move backward together. This allows the body massage unit 1100 to slide.

[0101] To allow movement of the upper frame 1132a, casters can be provided at the lower part of the upper frame 1132a. Additionally, a guide member can be provided at the upper part of the lower frame 1132b to guide the casters. The casters on the upper frame 1132a move along the guide member on the lower frame 1132b, thereby allowing the upper frame 1132a to move forward or backward.

[0102] According to another embodiment of the present invention, the massage device 1000 may not provide a sliding function. In this case, the base frame 1132 may not be separated into an upper frame and a lower frame.

[0197] The extension portion 2320 is configured to surround the inner side surface of the lower calf massage housing 2112 when it extends in the height direction from the second mounting portion 2310, thereby fixing the second sensor unit 2300 to the lower calf massage housing 2112. In addition, when the extension portion 2320 extends in the height direction from the second mounting portion 2310, the second sensor unit 2300 may be configured in a "匚" shape.

[0198] That is, the second sensor unit 2300 can be fixed by the second mounting portion 2310 being closely attached to the third groove 2113 and the second sensing unit 2330 being closely attached to the fourth groove 2114, and can be made in a "匚" shape or an "L" shape corresponding to the shape of the extension portion 2320.

[0199] Figure 6A A cross-sectional view in the height direction of the foot massage unit 2000 is shown. Figure 6B Enlarged view shows Figure 6A a part of Figure 6C Enlarged view shows the first groove for fastening the sensor unit. Figure 6D A perspective view of the first sensor unit 2200 is shown.

[0200] As one embodiment of this utility model, the first sensor portion 2200 can be configured to have a predetermined slope corresponding to the shape of the foot massage housing 2010. More preferably, the first sensor portion 2200 can be inserted obliquely in a direction approaching the calf massage portion 2100. In particular, the first sensor portion 2200 is located at the upper front end of the foot massage housing 2010 corresponding to the instep of the user, and can be configured along an oblique surface that rises rearward.

[0201] In particular, in the first sensor section 2200, the front end and the rear end of the first sensor section 2200 can be located at different heights from the lower end of the outer side of the lower foot massage housing 2012. More preferably, with the lower end of the outer side of the lower foot massage housing 2012 as a reference, the rear end of the first sensor section 2200 can be located at a relatively higher position than the front end of the first sensor section 2200.

[0202] The first mounting portion 2210 can be inserted into and fixed to the first groove 2013, and is configured to engage with the two ends of the first groove 2013 in terms of size. At this time, an elastic element (not shown) can be inserted between the two ends of the first groove 2013 and the mounting portion of the first sensor portion 2200 to prevent a predetermined gap, thereby making the mounting portion and the first groove 2013 tightly engaged.

[0203] Furthermore, one side of the first mounting portion 2210 is connected to the first sensing portion 2230, and the other side is connected to the locking portion 2220. The first sensing portion 2230 may be configured to have the same length as the first mounting portion 2210 in the longitudinal direction, and is configured to extend in the height direction from one end of the first mounting portion 2210 toward the lower end of the outer side of the lower foot massage housing 2012.

[0204] Furthermore, the first sensing unit 2230 is configured to accurately detect not only the position of the user's body parts but also the position of the foot massage unit 2000, thereby ensuring safety. Specifically, the first sensing unit 2230 includes a sensor element (not shown) for detecting the positional relationship with the foot massage unit 2000, and can ensure user safety by monitoring the operational status of the foot massage unit 2000 in real time.

[0205] More preferably, the sensor element can use mechanical, optical, magnetic, or electrical detection methods to detect the position of the foot massage unit 2000, and is designed to maximize safety under specific circumstances using each method.

[0206] The mechanical detection method includes a pressure detection element that is in direct contact with the foot massage unit 2000, and can immediately detect and control the action when the foot massage unit 2000 reaches a specific position or is subjected to abnormal pressure.

[0207] The optical detection method includes an optical sensor for detecting reflectors or optical marks located on the foot massage unit 2000, which can provide more accurate position information by detecting the position of the foot massage unit 2000 in a non-contact manner.

[0208] The magnetic detection method includes a magnetic field sensor that interacts with a magnetic material attached to the foot massage unit 2000, and detects the accurate position of the foot massage unit 2000 by detecting changes in the position of the magnetic material to ensure safety. The electrical detection method includes a capacitive sensor or an electrical sensor, and confirms the position by detecting changes in the electrical characteristics of the foot massage unit 2000. The first sensing unit 2230 confirms the position and operating state of the foot massage unit 2000 through such detection methods, and provides this information to the control unit to maintain safe operation.

[0209] Furthermore, the first sensing unit 2230 can be fixed to the second slot 2014 in various ways. As an example, a protrusion (not shown) is formed on the outer surface of the first sensing unit 2230, and a locking block (not shown) that engages with the protrusion can be formed on the inner side of the second slot 2014. Accordingly, when the first sensing unit 2230 is inserted into the second slot 2014, the protrusion engages with the locking block of the second slot 2014, thereby fixing the first sensing unit 2230.

[0210] In particular, the first sensing unit 2230 can be fastened to the second slot 2014 by a pin engagement or by a clip fastening. Therefore, when the first sensing unit 2230 is inserted into the second slot 2014, it can be stably fixed by one or more of the following methods: a locking fastening method, a pin fastening method, and a clip fastening method.

[0211] The locking portion 2220 is connected to the other end of the mounting portion and can be configured to have the same length as the mounting portion in the longitudinal direction. In particular, the locking portion 2220 is configured to extend in the height direction from the other end of the mounting portion toward the lower end of the inner side of the lower foot massage housing 2012.

[0212] The length of the locking portion 2220 in the height direction can be configured to be relatively shorter than the length of the first sensing portion 2230 in the height direction. That is, the first sensing portion 2230 is configured to have a larger cross-sectional area than the locking portion 2220. With this structure, the first sensing portion 2230 can expand its detection area, thereby enabling it to detect the movement of objects such as the user's body or other objects more widely.

[0213] Furthermore, the first sensor unit 2200 includes a first connector 2240 located inside the foot massage housing 2010, and the first connector 2240 can be configured to be energized with the first sensor plate 2430. In particular, the first connector 2240 is configured to protrude from the lower end of the locking portion 2220 and extend into the inner side of the lower leg housing.

[0214] Furthermore, the fastening hole 2241 is located inside the first connector 2240. The fastening hole 2241 is configured to fasten to the upper foot massage housing 2011, or to a wire electrically connected to the first sensor plate 2430. In particular, it can be configured to allow for bolt or pin fastening via a corresponding fastening part (not shown) on the upper foot massage housing 2011.

[0215] More preferably, a bolt passes through the fastening hole 2241 and is inserted, the bolt being able to engage with a threaded fastening portion (not shown) of the upper foot massage housing 2011. Furthermore, a pin passes through the fastening hole 2241 and is inserted in a manner that engages with a corresponding portion of the upper foot massage housing 2011.

[0216] Furthermore, the first connector 2240 is configured to connect to a wire via welding or other electrical connection methods, and to be energized to the first sensor board 2430 via the wire. As an example, in addition to welding, the first connector 2240 can also utilize crimp terminals, screw fastening, or clamping to achieve connection with the wire. More preferably, the wire can be fixed to the first connection hole 2241 formed inside the first connector 2240 via welding or other electrical connection methods.

[0217] Therefore, the first sensor unit 2200 is connected to a wire via the first connector 2240, thereby transmitting the electrical signal measured by the first sensor unit 2200 to the first sensor board 2430 via the wire. As described above, the transmission stability of the electrical signal can be further improved through various connection methods. Therefore, for the first sensor unit 2200, while placing the first mounting part 2210 into the first slot 2013, securing the first sensing part 2230 to the second slot 2014, and fixing the locking part 2220 to the lower foot massage housing 2012, it can be further fixed to the upper foot massage housing 2011 by bolt or pin fastening through the fastening hole 2241.

[0224] The second sensing unit 2330 is configured to extend in the length direction along the upper end of the outer side surface of the lower calf massage housing 2112 in a state where at least a part of it is connected to the second placement unit 2310. The second sensing unit 2330 may be inserted and fixed in the fourth groove 2114 formed by injection molding.

[0225] In addition, the second sensing unit 2330 may be fixed to the fourth groove 2114 in various coupling manners. As an example, a protrusion (not shown) is formed on the outer side surface of the second sensing unit 2330, and a clamping block (not shown) engaging with the protrusion may be formed inside the fourth groove 2114. Accordingly, when the second sensing unit 2330 is inserted into the fourth groove 2114, the protrusion engages with the clamping block of the fourth groove 2114, so that the second sensing unit 2330 can be fixed. In particular, the second sensing unit 2330 may be fastened to the fourth groove 2114 by a pin coupling method or by a clamping fastening method.

[0226] Therefore, when the second sensing unit 2330 is inserted into the fourth slot 2114, it can be fastened to the fourth slot 2114 by one or more of the locking fastening method, pin fastening method, and clip fastening method.

[0227] Furthermore, the second sensor portion 2300 can be inserted into and fixed to the inlet hole 2115 formed on the lower calf massage housing 2112. More preferably, the second sensor portion 2330 can be configured such that one end is bent in a predetermined step. By inserting one end of the second sensor portion 2330, which is bent in a predetermined step, into the inlet hole 2115, the second sensor portion 2300 can be fixed to the lower calf massage housing 2112.

[0228] The second sensor unit 2300 includes a second connector 2340 located inside the lower calf massage housing 2112, and the second connector 2340 can be configured to be energized with the second sensor plate 2431.

[0231] Furthermore, the second connector 2340 can be connected to the wire via various electrical connection methods and is configured to energize the second sensor board 2431 through the wire. For example, the second connector 2340 can be connected to the wire not only by soldering but also by spring terminals, quick connectors, or magnetic connections. More preferably, the second connector 2340 can be designed to include a separate electrical contact surface or a contact structure made of conductive material to enable a stable connection with the wire.

[0232] Therefore, the second sensor unit 2300 is connected to a wire via the second connector 2340, thereby transmitting the electrical signal measured by the second sensor unit 2300 to the second sensor board 2431 via the wire. Using these diverse connection methods enhances the stability of the electrical connection and also improves assembly efficiency.
