Description

Technical Field

[0001] This utility model relates to a massage device with a heating function, and provides a heating massage module designed to simultaneously provide appropriate heat and massage pressure to the user's body parts, thereby maximizing the effects of promoting blood circulation and relaxing muscles. Background Technology

[0002] Massage refers to the application of various forms of mechanical stimulation to specific parts of the body, such as kneading, acupressure, stretching, patting, or physical activity, in order to adjust changes in the body, improve blood circulation, and relieve fatigue.

[0003] The increased demand for massage, driven by economic factors and time constraints, has led to a surge in demand for massage devices or instruments that provide manual massage. Specifically, as the need to relieve stiff muscles and eliminate fatigue or stress through massage grows, various time- and cost-effective massage devices have been introduced.

[0004] In recent years, with increasing attention to health, massage devices have evolved from simple massage functions to electronic devices that provide a variety of additional and / or medical functions. Therefore, research on methods to effectively control massage devices continues.

[0005] Traditional massage devices use aluminum inserts and sintered structural components to ensure durability and thermal conductivity. These configurations provide stable operation during initial use and maintain high durability, especially in high-temperature environments. Furthermore, in devices incorporating heating functions, metal components are typically used to improve heat transfer efficiency, thereby enhancing the massage effect.

[0006] However, while traditional massage devices use aluminum inserts and sintered structural components to ensure durability and heat transfer efficiency, they also have some problems, such as noise caused by wear of the sintered structural components, reduced silicone durability due to aluminum inserts, increased production costs due to complex structures, and lubricant leakage between the massage balls and bearings.

[0007] To address these issues, research has been conducted in recent years on structural simplification, noise reduction technologies, and leak-proof structures utilizing plastic materials. In particular, the adjustable thermal conductivity of plastic materials allows for maintaining a uniform temperature distribution when combined with heating functions, thus driving ongoing research in this area.

[0096] The leg massage unit 1300 includes a receiving space for accommodating a user's legs and can provide leg massage to the user by massaging at least a portion of the user's legs. For example, the leg massage unit 1300 may include a calf massage unit for massaging the user's lower legs and / or a foot massage unit for massaging the user's feet.

[0097] The leg massage unit 1300 can be adjusted in length according to the user's body characteristics. For example, when a tall user uses the massage device 1000, the leg massage unit 1300 needs to be longer because the lower leg is longer. Conversely, when a short user uses the massage device 1000, the leg massage unit 1300 needs to be shorter because the lower leg is shorter. Thus, the leg massage unit 1300 can provide a leg massage customized to the user's height. According to one embodiment of this invention, the user can control the massage device 1000 using a massage device control device CD. The massage device control device CD can be connected to the massage device 1000 via wired and / or wireless communication.

[0099] Figure 2 This is a diagram illustrating the main frame according to an embodiment of the present invention.

[0100] According to one embodiment of the present invention, the main frame 1130 may include an upper frame 1131 on which a massage module 1110 is provided and a base frame 1132 for supporting the upper frame 1131.

[0101] The upper frame 1131 may be provided with a rack along its length. The rack, as a component guiding the massage module 1110 to move up and down, can be configured to use a known rack including multiple valleys and multiple spines.

[0102] According to one embodiment of the present invention, the rack can be arranged facing each other on both sides of the upper frame 1131, and the massage module 1110 can move along the rack.

[0103] The rack is formed along the vertical direction, but is not limited thereto. The rack may include a front-to-back direction rack and a vertical direction rack. In this invention, the front-to-back direction can refer to the direction from the massage module 1110 toward the user or the direction from the user toward the massage module 1110, and can refer to... Figure 2 The X-axis direction is the reference point.

[0104] 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-rear direction and a rack in the up-down direction, respectively. The gears are rotated by an actuator disposed on the massage module 1110, thereby allowing the massage module 1110 to move forward, backward, upward, or downward.

[0105] As the massage module 1110 moves forward, the massage intensity can increase. Conversely, as the massage module 1110 moves backward, the massage intensity can decrease.

[0106] 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.

[0107] The upper frame 1131 can be implemented in various shapes. For example, the upper frame 1131 can be classified into S-frame, L-frame, S&L-frame and double S&L-frame according to its shape, but is not limited to these.

[0108] An S-frame refers to a frame in which at least a portion of the upper frame 1131 includes a shape that is curved like an "S". An L-frame refers to a frame in which at least a portion of the upper frame 1131 has a bend shape similar to an "L". An S&L frame refers to a frame that includes both a bend shape similar to an "S" and a bend shape similar to an "L". A double S&L frame refers to a frame that includes a bend shape similar to an "L" and two parts that have bend shapes similar to an "S".

[0109] The base frame 1132 refers to the part that supports the upper frame 1131 and is in contact with the ground. The base frame 1132 may include an upper base frame 1132a and a lower base frame 1132b.

[0110] The upper base frame 1132a can support the upper frame 1131, and the lower base frame 1132b can contact the ground. In addition, the upper base frame 1132a can be arranged in contact with the lower base frame 1132b.

[0111] According to one embodiment of the present invention, the upper base frame 1132a can move along the lower base frame 1132b. For example, the upper base frame 1132a can slide forward or backward along the lower base frame 1132b. In this case, the upper frame 1131 is connected to the upper base frame 1132a, and thus can move as the upper base frame 1132a moves.

[0112] For example, when the upper frame 1132a moves forward, the upper frame 1131 can also move forward together; when the upper frame 1132a moves backward, the upper frame 1131 can also move backward together. This allows the body massage unit 1100 to slide.

[0113] To allow movement of the upper base frame 1132a, a wheel can be provided at the lower part of the upper base frame 1132a. Furthermore, a guide member capable of guiding the wheel can be provided at the upper part of the lower base frame 1132b. The wheel on the upper base frame 1132a moves along the guide member on the lower base frame 1132b, thereby allowing the upper base frame 1132a to move forward or backward.

[0114] 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.

[0115] Figure 3 This is a diagram illustrating the detailed configuration of a massage control device according to an embodiment of the present invention.

[0121] The back angle actuator is an actuator that adjusts the angle of the part of the massage device 1000 that contacts the user's back. Its movement adjusts the back angle of the massage device 1000. The leg angle actuator is an actuator that adjusts the angle of the leg massage section 1300 of the massage device 1000. Its movement adjusts the angle between the leg massage section 1300 and the body massage section 1100. The foot massage actuator is an actuator used to actuate the foot massage module included in the leg massage section 1300. For example, the control unit 1400 can provide foot massage to the user using the foot massage actuator. The leg length actuator is an actuator that adjusts the length of the leg massage section 1300. For example, the control unit 1400 can use the leg length actuator to adjust the length of the leg massage section 1300 according to the user, resulting in a massage that suits the user's body shape.

[0122] The massage module 1110 includes at least one actuator, which can be a variety of actuators such as a movement actuator, a forward / backward actuator, and a massage actuator.

[0155] Reference Figure 5 The massage module 1110 includes: a module base disposed on the massage device 1000; a massage drive unit providing at least one of the following: vibration, linear motion, rotational motion for body massage, and power for adjusting the massage position; a unit bracket 1500 connected to the massage drive unit; and a massage unit 2000 disposed at the upper and lower ends of the unit bracket 1500 and applying pressure and heat to the user's body.

[0156] The module base moves up and down along the inside of the backrest of the massage chair via a transfer device. Multiple massage units 2000 are symmetrically arranged at the front of the module base, and a massage drive unit for operating the massage units 2000 is located at the rear of the module base. The massage drive unit provides power to perform tapping or kneading massage actions by causing the massage units 2000 to vibrate back and forth or to perform linear, circular, or elliptical rotational motions. This massage drive unit can be configured to utilize the massage drive device in a known massage module 1110 configured in a massage chair that provides power for the kneading, tapping, and massage position (depth) adjustment of the massage units 2000.

[0157] For example, the massage drive unit may include: multiple motors; and a power transmission device that transmits power from each motor to the unit support 1500. The power transmission device may be configured by appropriately combining cams, gears, timing belts, linkages, etc.

[0158] The unit support 1500 is made of a roughly "V" shaped metal plate and receives power by connecting to the massage drive unit, thereby moving forward, backward, and left and right.

[0159] In this embodiment, there are two massage units 2000, which are respectively attached to the upper and lower ends of the unit support 1500. However, the number and position of the massage units 2000 attached to each unit support 1500 can be adjusted as needed.

[0160] The multiple massage units 2000 set in the unit support 1500 can all have massage and heating functions, but in contrast, some of the multiple massage units 2000 can only have massage and heating functions.

[0161] like Figure 6As shown, the massage unit 2000, which combines massage and heating functions, includes a support shaft component 2110, a heating component 2120, a cushioning component 2130, a bearing 2140, a first side bearing 2160, a second side bearing 2170, and a reinforcing component 2113.

[0162] More specifically, the massage unit 2000 includes: a cover 2114 fixedly disposed at the end of the unit support 1500 and made of a thermally conductive material; a reinforcing member 2113 located on the upper side of the cover 2114; a support shaft member 2110 inserted into the reinforcing member 2113 and fastened to the cover 2114; a heating member 2120 configured to transfer heat to the support shaft member 2110; a cushioning member 2130 rotatably disposed on the outer surface of the support shaft member 2110 and applying pressure to the user's body; a bearing 2140 inserted into the inner circumferential surface of an opening disposed in the center of the cushioning member 2130; a first side bearing 2160 located on the upper side of the bearing 2140; and a second side bearing 2170 located on the lower side of the bearing 2140.

[0163] The support shaft member 2110 functions both as a rotation axis for the cushioning member 2130 (which functions as a massage device) and as a support structure supporting the constituent elements relative to the unit bracket 1500. It includes: a cylindrical body portion 2111, one end (the axially inner end) of which is fixedly attached to the unit bracket 1500 via a cover portion 2114; and a flange portion 2112, which protrudes radially outward from the other end (the axially outer end) of the body portion 2111. Furthermore, the flange portion 2112 is disposed on the side of the cushioning member 2130, and the body portion 2111 extends from the flange portion 2112 along the inner circumferential surface of the cushioning member 2130.

[0164] A taphole with threads formed on its inner circumferential surface is provided at the axial inner end of the body portion 2111 of the support shaft member 2110 so that the cover portion 2114 can be fastened by bolts or screws. Furthermore, a heating cavity is recessed in the center of the body portion 2111 so that the heating member 2120 can be inserted and disposed thereon.

[0165] The heating element 2120 includes: a heater, inserted into the heating chamber formed in the body portion 2111 of the support shaft member 2110, and generating heat through a power supply provided by the control module of the massage device 1000; a temperature sensor, measuring the temperature used to control the operation of the heater; and a bimetallic strip, which automatically cuts off the power supply to the heater when the support shaft member 2110 heats up to a certain temperature in case of temperature sensor failure or malfunction, and restores power to the heater when the support shaft member 2110 cools down to a certain temperature. Furthermore, a corrugated heater spring can be provided on one side of the heater to improve heat transfer performance and prevent vibration by tightly fitting the heater against one side of the heating chamber. The heater can be a PTC heater, but is not limited to this, and can also be any known heater.

[0166] The cushioning member 2130 consists of a roller or spherical structure with an opening in the center for the insertion of the support shaft member 2110, and is made of a material with excellent elasticity and thermal conductivity, such as silicone, which can provide the user with a soft massage sensation and provide the user with the heat transferred from the support shaft member 2110.

[0167] The bearing 2140 is inserted into the inner circumferential surface of the opening of the buffer member 2130, thereby both transferring the heat of the support shaft member 2110 to the buffer member 2130 and maintaining the shape of the buffer member 2130.

[0168] Figures 7 to 8D It is an enlarged view showing the side sectional view of the massage module 1110, the side sectional view for fastening the bearing 2140, and the fastening relationship between the side bearing and the buffer member 2130.

[0169] like Figure 7 As shown, according to an embodiment of the present invention, the massage unit 2000 is disposed on the upper end of the cover 2114 fastened to one side of the unit bracket 1500.

[0170] The cover 2114 can be secured to the unit bracket 1500 via a fastening port and is configured to absorb vibration and torsional loads on the massage unit 2000 generated during operation of the massage unit 2000. Furthermore, the cover 2114 includes a coating or heat sink with excellent thermal conductivity.

[0171] The support shaft member 2110 of the massage unit 2000 is fastened to the cover portion 2114, and the outer peripheral surface of the support shaft member 2110 is wrapped by the reinforcing member 2113 and the bearing 2140. More preferably, the reinforcing member 2113 is fastened to the cover portion 2114, and the bearing 2140 is located on the upper side of the reinforcing member 2113.

[0172] The support shaft member 2110 consists of a flange portion 2112 and a body portion 2111. Furthermore, the body portion 2111 is cylindrical, and the flange portion 2112 may be formed on one end face of the cylindrical body portion 2111 and has a shape that protrudes from the outer peripheral surface of the body portion 2111. Additionally, the outer peripheral surface of the body portion 2111 is configured to be enclosed by a reinforcing member 2113 and a bearing 2140.

[0173] The bearing 2140 is configured to enclose the outer peripheral surface of the body portion 2111 and may have a cylindrical shape corresponding to the body portion 2111. Furthermore, the bearing 2140 is disposed between the support shaft member 2110 and the buffer member 2130, allowing the buffer member 2130 to rotate with respect to the support shaft member 2110. More preferably, the inner peripheral surface of the bearing 2140 may be configured to be spaced apart from the outer peripheral surface of the body portion 2111 by a predetermined interval, and the outer peripheral surface of the bearing 2140 may be configured to contact the surface of the buffer member 2130. Alternatively, the flange portion 2112 and the reinforcing member 2113 of the support shaft member 2110 may be located at opposite ends of the bearing 2140.

[0174] With the support shaft member 2110 as a reference, the buffer member 2130 and the bearing 2140 can rotate as a whole. Therefore, the outer peripheral surface of the bearing 2140 can be made of a plastic material with a coefficient of friction of more than a set value and support the buffer member 2130.

[0175] The inner circumferential surface of bearing 2140 is tightly engaged with the outer circumferential surface of support shaft member 2110, and the outer circumferential surface of bearing 2140 contacts the inner circumferential surface of buffer member 2130 and rotates integrally with buffer member 2130.

[0176] Furthermore, the bearing 2140 can be coupled to the buffer member 2130 with an interference fit and rotate as a whole. Alternatively, the bearing 2140 can rotate as a whole with the buffer member 2130 by inserting the fastening part 2142 formed on the outer peripheral surface of the bearing 2140 into the fastening groove 2132 of the buffer member 2130.

[0177] More preferably, when the buffer member 2130 applies pressure to the user, the external force is applied in the direction of contact with the outer peripheral surface of the bearing 2140, and the buffer member 2130 and the bearing 2140 can make surface contact through the applied external force so as to rotate as a whole.

[0178] Furthermore, the coefficients of friction of the inner and outer circumferential surfaces of the bearing 2140 are configured to have different values. In particular, in this embodiment, the coefficient of friction of the outer circumferential surface of the bearing 2140 is designed to have a relatively larger value than that of the inner circumferential surface, so that the buffer member 2130 can rotate integrally with the outer circumferential surface of the bearing 2140. In addition, to enhance the friction with the buffer member 2130 and achieve integral rotation, the outer circumferential surface of the bearing 2140 may be subjected to micro-embossing or coated with a material with a high coefficient of friction.

[0179] In contrast, the inner circumferential surface of bearing 2140 is the region that generates friction when rotating with respect to the support shaft member 2110, and its coefficient of friction is configured to have a relatively lower value than that of the outer circumferential surface. Through this difference in the coefficients of friction between the inner and outer circumferential surfaces of bearing 2140, bearing 2140 can rotate with respect to the support shaft member 2110 and move integrally with the buffer member 2130.

[0180] Furthermore, the bearing 2140 may be made of plastic material. More preferably, the bearing 2140 may include at least one of polytetrafluoroethylene (PTFE), polyamide (PAI), polyetheretherketone (PEEK), polyethylene (PE), polyoxymethylene (POM), tin, and bismuth.

[0181] Furthermore, in this embodiment, the bearing 2140 is cylindrical in shape, and a groove 2150 is provided on the inner circumferential surface of the bearing 2140 along the height direction of the inner circumferential surface.

[0182] The groove 2150 is configured to store lubricant and supply it to the inner circumferential surface of the bearing 2140. Furthermore, a plurality of grooves 2150 may be arranged at predetermined intervals along the circumferential direction on the inner circumferential surface of the bearing 2140. More preferably, the plurality of grooves 2150 forming the same interval may have a semi-circular, U-shaped, or V-shaped cross-sectional shape. The depth of the groove 2150 may vary depending on the composition of the lubricant.

[0183] Furthermore, the grooves 2150 can be provided continuously or discontinuously along the length of the inner circumferential surface of the bearing 2140. In particular, a plurality of grooves 2150 arranged parallel to each other along the height direction can be configured to have the same spacing along the height direction of the bearing 2140.

[0184] Furthermore, the first side bearing 2160 and the second side bearing 2170 are located at opposite ends of the outer peripheral surface of the bearing 2140. More preferably, the first side bearing 2160 may be at least partially engaged with the end of the bearing 2140 adjacent to the flange portion 2112, and is configured to be adjacent to the inner surface of the buffer member 2130. Furthermore, the second side bearing 2170 is configured to contact the other end of the bearing 2140 adjacent to the reinforcing member 2113, and at least a portion thereof is in contact with the buffer member 2130. Moreover, the radii of the inner peripheral surfaces of the first side bearing 2160 and the second side bearing 2170 are configured to have relatively larger values ​​than the radius of the cylindrical inner peripheral surface of the bearing 2140. More preferably, the radius of the outer peripheral surface of the bearing 2140 is substantially the same as the radius of the inner peripheral surfaces of the first side bearing 2160 and the second side bearing 2170. The outer peripheral surfaces of the first side bearing 2160 and the second side bearing 2170 can be configured to protrude from the outer peripheral surface of the bearing 2140 along the width direction.

[0185] Bearing 2140 can be coupled to the first side bearing 2160 and the second side bearing 2170 via an interference fit. Alternatively, at least a portion of the first side bearing 2160 and the second side bearing 2170 can be inserted into and secured to bearing 2140. Bearing 2140 can rotate integrally with the first side bearing 2160 and the second side bearing 2170 by coupling with them.

[0186] The first side bearing 2160 is disposed adjacent to the flange portion 2112, and at least a portion of the first side bearing 2160 is inserted and fixed to the flange portion 2112. Furthermore, the outer peripheral surfaces of the buffer member 2130 and the first side bearing 2160 may be configured to be in surface contact.

[0187] More preferably, the first side bearing 2160 may include a first flow prevention portion 2161, which protrudes from the upper surface of the first side bearing 2160 toward the flange portion 2112. The first flow prevention portion 2161 is inserted into a first flow prevention groove 2162 formed in the flange portion 2112. Thus, the first side bearing 2160 can be fixed to the flange portion 2112.

[0188] A first flow prevention groove 2162 is formed on the surface of the flange portion 2112 corresponding to the first side bearing 2160, and is disposed near the boundary where the flange portion 2112 meets the body portion 2111. Furthermore, corresponding to the position of the first flow prevention groove 2162, the first flow prevention portion 2161 may be located adjacent to the inner edge of the first side bearing 2160. The first flow prevention portion 2161 is configured to rotate circumferentially along the first flow prevention groove 2162 when engaged with it.

[0189] Furthermore, the first flow prevention portion 2161 can be manufactured in a shape corresponding to the shape of the first flow prevention groove 2162. The first flow prevention groove 2162 can be configured with a semi-circular, U-shaped, or quadrilateral cross-sectional shape, and corresponding to the shape of the first flow prevention groove 2162, the shape of the first flow prevention portion 2161 can be configured with a semi-circular, U-shaped, or quadrilateral cross-sectional shape.

[0190] The end of the first side bearing 2160 is configured to extend radially further from the central axis in the height direction of the support shaft member 2110 than the end of the flange 2112. The end of the first side bearing 2160 away from the flange 2112 may be wrapped by the buffer member 2130. Furthermore, the height direction length of the end of the first side bearing 2160 may be shorter than the height direction length of the buffer member 2130 that contacts the end of the first side bearing 2160.

[0191] Furthermore, the first side bearing 2160 includes a protrusion 2180 extending along one side of the buffer member 2130. The protrusion 2180 is inserted into and fixed in a groove 2131 formed in the buffer member 2130.

[0192] Therefore, the protrusion 2180 located on the first side bearing 2160 can be inserted into the groove 2131, thereby rotating integrally with the buffer member 2130.

[0193] During the integral rotation of the first side bearing 2160 and the buffer member 2130, the flange portion 2112 restricts the rise of the first side bearing 2160 in the height direction at the upper end of the first side bearing 2160.

[0194] The second side bearing 2170 is configured to face the reinforcing member 2113, which is configured to support the second side bearing 2170.

[0195] Furthermore, the second side bearing 2170 includes a second flow prevention portion 2171 inserted into a second flow prevention groove 2172 located in the reinforcing member 2113. The second flow prevention groove 2172 is formed on the reinforcing member 2113 adjacent to the second side bearing 2170 and is disposed adjacent to the outer peripheral surface of the body portion 2111.

[0196] Furthermore, the second flow prevention groove 2172 can be configured with various cross-sectional shapes, and the second flow prevention portion 2171 can be configured with a shape corresponding to the shape of the second flow prevention groove 2172. In addition, the second flow prevention portion 2171 rotates in the circumferential direction when engaged with the second flow prevention groove 2172.

[0197] Furthermore, the second side bearing 2170 is fastened to the buffer member 2130 in the same manner as the fastening between the first side bearing 2170 and the buffer member 2130.

[0198] The second side bearing 2170 and the buffer member 2130 are fastened together, allowing the second side bearing 2170 and the buffer member 2130 to rotate together. Furthermore, the force in the height direction generated when the second side bearing 2170 and the buffer member 2130 rotate together is applied to the second side bearing 2170. Therefore, in the second side bearing 2170, the force in the height direction applied from the buffer member 2130 is counteracted by the reinforcing member 2113, thereby limiting the height direction movement of the bearing 2140, the first side bearing 2160, and the second side bearing 2170.

[0199] This includes a groove configured to surround the outer peripheral surface of the bearing 2140. The outer side of the groove is configured to be surrounded by a first side bearing 2160 and a second side bearing 2170, thereby forming a flow groove 2141. More preferably, the flow groove 2141 is formed by a buffer member 2130 surrounding the groove formed on the outer peripheral surface of the bearing 2140 or by the space formed by being surrounded by the first side bearing 2160 and the second side bearing 2170.

[0200] Furthermore, the flow grooves 2141 can be located on the outer peripheral surfaces of the bearing 2140 opposite to the first side bearing 2160 and the second side bearing 2170, respectively, and the first side bearing 2160 and the second side bearing 2170 can be configured such that their cross-sectional areas become wider as they move away from the flow grooves 2141 adjacent to each other. Therefore, lubricant applied to the inner side of the bearing 2140 along the flow grooves 2141 can flow along the outer peripheral surface of the bearing 2140.

[0201] Furthermore, one end of the flow channel 2141 can communicate with the groove 2150. The other end of the flow channel 2141 can communicate with a shape that is open inside the protrusion 2180. More preferably, the protrusion 2180 has a shape in which its lower part is open, and the holding part 2181 is located in the part in which its lower part is open.

[0202] That is, the container 2181 is connected to the flow groove 2141 formed on the outer peripheral surface of the bearing 2140, and the flow groove 2141 is configured to communicate with the groove 2150. Thus, the lubricant that is dispersed from the groove 2150 can move along the outer peripheral surface of the bearing 2140 and flow into the container 2181 through the flow groove 2141.

[0203] When the bearing 2140 rotates, the lubricant moves along the groove 2150 to both ends in the height direction of the groove 2150. The movement of the lubricant in the width direction at the two ends of the groove 2150 is restricted by the first flow prevention part 2161 and the second flow prevention part 2171. That is, when the bearing 2140 rotates, the first flow prevention part 2161 and the second flow prevention part 2171 prevent the lubricant from leaking to the outside.

[0204] More specifically, the lubricant located inside the groove 2150 moves in the width direction along the flange 2112 or the reinforcing member 2113 by the centrifugal force generated by the rotational movement of the bearing 2140. The first flow prevention part 2161 and the second flow prevention part 2171 suppress the movement of the lubricant in the width direction and retain the lubricant on the bearing 2140, the first side bearing 2160 and the second side bearing 2170.

[0205] Lubricant whose movement in the width direction is restricted by the first flow prevention part 2161 and the second flow prevention part 2171 can flow into the holding part 2181 through the flow channel 2141.

[0206] The lubricant that reaches the two ends of the groove 2150 by the rotational movement of the bearing 2140 can descend in the height direction while its movement in the width direction is restricted by the first flow prevention part 2161 and the second flow prevention part 2171, and flow into the gap between the protrusion 2180 and the groove 2131, and then flow into the holding part 2181.

[0207] When the bearing 2140 completes its rotation, the lubricant stored in the container 2181 flows into the gap between the protrusion 2180 and the groove 2131, and then flows back into the groove 2150 via the flow channel 2141.

[0208] To increase the storage space for the lubricant and to hold it in place, the inner surface of the container 2181 can be formed with various patterns. More preferably, fine grooves or embossed patterns can be formed on the inner surface of the container 2181.

[0209] Embossing patterns utilize the surface tension of the lubricant to hold it in place. These embossed patterns can be evenly arranged on the inner wall of the container 2181 and can take various shapes depending on the viscosity or working environment. For example, the embossed pattern can be hemispherical, grid-shaped, or linear.

[0210] The buffer member 2130 can be coupled to the bearing 2140 in an interference fit manner. When the buffer member 2130 and the bearing 2140 are coupled in the interference fit manner and an external force is applied to the buffer member 2130, the buffer member 2130 can be tightly attached to the bearing 2140 and rotate as a whole.

[0211] Furthermore, recesses 2131 are provided on both sides of the buffer member 2130 for the protrusions 2180 to be inserted. Multiple recesses 2131 may be provided on both sides of the buffer member 2130 at a certain distance along the circumferential direction. Moreover, the number of recesses 2131 may correspond to the number of protrusions 2180.

[0212] Furthermore, the engagement of the groove 2131 and the protrusion 2180 allows the buffer member 2130 to rotate integrally with the first side bearing 2160 and the second side bearing 2170. Additionally, the engagement of the groove 2131 with the protrusion 2180 fixes the position of the buffer member 2130 in both the height and width directions during its rotational movement.

[0213] Furthermore, the buffer member 2130 includes a joint portion 2133 that contacts the surface of the first side bearing 2160 or the second side bearing 2170. The joint portion 2133 may be located between at least two recess portions 2131 and is configured as an inclined surface inclined at a predetermined angle according to the shape of the first side bearing 2160 and the second side bearing 2170, and its shape may be made in a variety of ways.

[0214] In summary, the massage unit 2000 according to an embodiment of the present invention includes a bearing 2140, a buffer member 2130, a first side bearing 2160, and a second side bearing 2170. Stable rotational movement of the first side bearing 2160, the second side bearing 2170, and the buffer member 2130 is achieved through the engagement between the protrusion 2180 and the groove 2131. Furthermore, a plurality of grooves 2150 for storing and distributing lubricant are formed on the inner circumferential surface of the bearing 2140, and the holding portion 2181, the first flow prevention portion 2161, and the second flow prevention portion 2171 prevent lubricant from scattering or leaking, and maintain a lubricated state to enable the operation of the massage unit 2000.

[0217] According to another embodiment of the present invention, a mounting groove 2143 may be formed in the bearing 2140, and the mounting portion 2190 included in the first side bearing 2160 and the second side bearing 2170 is inserted into the mounting groove 2143.

[0218] A mounting groove 2143 is formed on the outer peripheral surface of the bearing 2140, and the mounting groove 2143 is configured to have a predetermined depth and width along the outer peripheral surface of the bearing 2140.

[0219] The mounting portion 2190 inserted into the mounting groove 2143 can be formed to correspond to the shape of the mounting groove 2143. More preferably, the mounting portion 2190 is formed to protrude from the inner peripheral surfaces of the first side bearing 2160 and the second side bearing 2170 toward the direction facing the support shaft member 2110.

[0220] The mounting part 2190 can be inserted and fixed in the mounting groove 2143 by interference fit. Through the combination of the mounting part 2190 and the mounting groove 2143, the bearing 2140 rotates integrally with the first side bearing 2160 and the second side bearing 2170.

[0221] like Figure 9As shown in the left-side fastening structure, in the bearing 2140 including the mounting groove 2143, the mounting portions 2190 of the first side bearing 2160 and the second side bearing 2170 are inserted into and disposed inside the mounting groove 2143 formed in the bearing 2140. In comparison, see... Figure 9 When the right-side fastening structure is in place, the inner surface of the bearing 2140 includes a groove 2150.

[0222] That is, as an embodiment of the present invention, the groove 2150 and the mounting groove 2143 can be arranged intersectingly along the circumferential direction on the inner and outer circumferential surfaces of the bearing 2140.

[0223] Furthermore, the mounting groove 2143 forms a multi-level snap-fit ​​structure along its width to enhance the bonding strength with the mounting portion 2190, and the shape of the mounting portion 2190 corresponding to the multi-level snap-fit ​​structure may include a structure that is respectively fastened to each level. Therefore, at least a portion of the mounting portion 2190 can be fixed to the snap-fit ​​step portion (not shown) formed in the mounting groove 2143.

[0224] Furthermore, multiple mounting slots 2143 may be arranged at predetermined intervals along the circumferential direction on the outer peripheral surface of the bearing 2140. In addition, the number of mounting slots 2143 is configured to correspond to the number of mounting portions 2190.

[0225] According to another embodiment of the present invention, the protrusion 2180 can be formed by an arc-shaped rib or a grid-shaped protrusion, and configured to have a continuous shape along the circumferential direction of the first side bearing 2160 and the second side bearing 2170, or multiple protrusions can be arranged at predetermined intervals. Furthermore, the arc-shaped protrusion 2180 can be configured to have an open interior, which can be configured as a holding portion 2181.

[0226] In another embodiment, the protrusion 2180 may be wrapped with a sealing portion to enhance the friction with the buffer member 2130, or the outer surface of the protrusion 2180 may be coated with a sealing material.

[0227] More preferably, a high-friction coefficient material, such as synthetic rubber, polyurethane, or silicone, is coated on the outer surface of the protrusion 2180 to increase the friction between the protrusion 2180 and the groove 2131. Furthermore, micro-protrusions and embossed patterns can be formed on the outer surface of the protrusion 2180 to increase the contact area with the groove 2131.

[0228] As another embodiment of the present invention, the buffer member 2130 has grooves 2131 formed on its two sides to relieve vibration and torsional loads. The grooves 2131 can be made to correspond to the shape of the protrusions 2180 in another embodiment of the present invention.

[0229] More preferably, when the protrusion 2180 is composed of an arc-shaped protrusion, the groove 2131 can be formed into a continuous groove shape along the circumferential direction so that the arc-shaped protrusion can be inserted into the groove 2131. Furthermore, the groove 2131 is formed adjacent to the inner edge of the buffer member 2130.

[0230] Furthermore, in other embodiments of this invention, the inner surface of the groove 2131 of the buffer member 2130 can be composed of various patterns, thereby increasing the contact area with the protrusion 2180. More preferably, a fine embossed pattern can be further applied to the inner surface of the groove 2131.

[0231] The shape and size of the pattern on the inner surface of the groove 2131 can be designed in a variety of ways depending on the material of the protrusion 2180 and the usage environment of the groove 2131.

[0232] According to another embodiment of the present invention, the buffer member 2130 further includes structural features such as an arc-shaped groove 2131 and an embossed pattern on the inner surface of the groove 2131, thereby increasing the contact area and friction with the protrusion 2180.

[0233] As another embodiment of this utility model Figure 11A This is an enlarged view showing bearing 2140. Figure 11B This is an enlarged view showing the buffer member 2130. Figure 11C The diagram shows either the first side bearing 2160 or the second side bearing 2170.

[0234] According to another embodiment of the present invention, a bearing 2140 includes a fastening portion 2142 on its outer peripheral surface to increase the bonding force with the buffer member 2130. The fastening portion 2142 extends along the height direction of the bearing 2140 on the outer peripheral surface of the bearing 2140. A plurality of fastening portions 2142 are arranged at predetermined intervals along the circumferential direction on the outer peripheral surface of the bearing 2140.

[0235] The plurality of fastening portions 2142 can be inserted into fastening grooves 2132 formed on the inner circumferential surface of the buffer member 2130 in another embodiment of the present invention. Furthermore, a high-friction coefficient material such as synthetic rubber or polyurethane can be coated on the surface of the fastening portions 2142 to increase the friction with the inner circumferential surface of the buffer member 2130. In addition, to improve durability, the fastening portions 2142 can be made of high-strength plastics such as polyoxymethylene or polyetheretherketone.

[0236] Furthermore, the fastening portion 2142 can be fastened to the insertion groove 2182 included in the first side bearing 2160 and the second side bearing 2170 according to another embodiment of the present invention. That is, the fastening portion 2142 extends in length in the height direction, so that both ends of the fastening portion 2142 can be inserted into the insertion groove 2182. Therefore, the fastening portion 2142 is inserted into the fastening groove 2132 and the insertion groove 2182, and is integrally combined with the buffer member 2130, the first side bearing 2160 and the second side bearing 2170.

[0237] Through this combination, bearing 2140 can rotate integrally with buffer member 2130, first side bearing 2160 and second side bearing 2170.

[0238] Furthermore, the fastening part 2142 may include a radially protruding pin (not shown) extending in the height direction, and the insertion part (not shown) may be inserted into a pin groove (not shown) formed inside the fastening groove 2132, thereby fastening the bearing 2140 and the buffer member 2130 to each other.

[0239] Furthermore, a stop (not shown) protruding toward the buffer member 2130 may be formed in the fastening portion 2142 to increase the bonding force with the fastening groove 2132. The two ends of the stop in the height direction of the fastening portion 2142 are arranged at a predetermined interval along the circumferential direction on the outer edge of the fastening portion 2142, thereby restricting the movement of the fastening portion 2142 in the height direction within the fastening groove 2132.

[0240] In another embodiment of the present invention, the bearing 2140, including the fastening part 2142, has a plurality of grooves 2150 on its inner circumferential surface and a plurality of fastening parts 2142 on its outer circumferential surface.

[0241] The fastening grooves 2132 and the fastening parts 2142 are formed in corresponding numbers and shapes. The cross-section of the fastening part 2142 can be made into various shapes, such as semi-circular, elliptical, quadrilateral, triangular, polygonal, etc.

[0242] Furthermore, the fastening groove 2132 can be configured such that its cross-sectional area gradually increases or decreases along the height direction of the buffer member 2130 according to the shape of the fastening part 2142.

[0243] Therefore, a groove 2131 is provided on both sides of the buffer member 2130 including the fastening part 2142, and a fastening groove 2132 extending in the height direction is provided on its inner circumferential surface.

[0244] In summary, this invention maximizes the stability and efficiency of rotary motion by optimizing the structure of the bearing 2140, the buffer member 2130, and the side bearing of the massage module 1110.
