Description

Technical Field

[0001] This utility model relates to a body care device, and more specifically to a body care device capable of providing massage through physical stimulation of the body of a seated user.

[0002] Priority information:

[0003] Korean Patent Application No.: 10-2024-0091667 (2024-07-11);

[0004] Korean Patent Application No.: 10-2024-0137315 (2024-10-10) Background Technology

[0005] In recent years, with the increasing aging of society, people of all ages, regardless of gender, are becoming more aware of the importance of health management, maintenance, and improvement. As a result, more and more people are making use of medical facilities or facilities such as sports clubs to manage, maintain, or improve their health.

[0006] Furthermore, just as much as maintaining or improving health and physical strength, many people are simultaneously striving to recover from fatigue or eliminate stress. To this end, various body care devices, such as massage tools, have been developed and are widely used in daily life.

[0007] Massage is a type of adjunctive medical therapy that uses hands or special tools to sweep, knead, press, pull, pat, or move the body to promote blood circulation and relieve fatigue. Instruments that perform massage through mechanical devices are called massage tools, and various mechanical elements are used in massage tools to ensure effective massage.

[0008] Among them, massage chairs, which are electric chairs that provide massage to the body on a seated chair structure, have been increasingly popular in recent years, not only among middle-aged and elderly people, but also among working professionals suffering from chronic fatigue and stress, as well as young women interested in beauty and weight loss.

[0009] Regarding the body care device that performs massage on the body of a seated user as described above, Korean Patent No. 10-1144812 (hereinafter referred to as "Prior Document 1") discloses a massage chair and its control method.

[0010] Specifically, a massage chair is disclosed, comprising: a backrest frame supporting a user's back; a seat frame rotatably coupled to the backrest frame supporting the user's buttocks; a reclining drive unit for tilting the backrest frame; a sliding drive unit for moving the seat frame in a forward-backward direction; and a control unit that, corresponding to the amount by which the reclining drive unit tilts the backrest frame and causes the upper end of the backrest frame to retract, causes the sliding drive unit to move the seat frame and cause the upper end of the backrest frame to advance.

[0011] However, the body care device in the existing literature 1 does not have an additional structure to cover the face of the seated user. The problem with this is that when the user is using the massage chair, bright lights from the ceiling may interfere with sleep and rest.

[0012] Especially when users want to recline the backrest frame to use the massage chair in a more comfortable position, their faces will be exposed to the ceiling light over a larger area. The problem here is that this structure may actually hinder the user's comfortable use due to glare.

[0013] In addition, Korean Patent No. 10-2249443 (hereinafter referred to as "Prior Document 2") discloses a massage chair that can provide oxygen and sterilization.

[0014] Specifically, a massage chair that provides oxygen and sterilization is disclosed, comprising: a chair frame having a seat, a backrest, and a headrest; a cushion covering the seat, backrest, and headrest; a main body forming on the rear surface of the headrest; a cover rotatably attached to the main body and forming to cover the front surface of the headrest; and a hinge that allows the cover to rotatably attach to the main body.

[0015] However, although the body care device in the existing document 2 is a structure that can rotate the cover to cover the user's face as needed, there is a problem that the user's head may collide with the cover when the simply hinged cover rotates.

[0016] Especially when users want to recline and use the massage chair in a more comfortable position, the problem is that this structure is greatly limited when used with reclining body care devices, for example, it may interfere with the operation of the cover when adjusting the angle of the backrest.

[0017] In the case of a body care device that massages the body of a seated user, there are challenges that must be addressed in order to construct a structure that is both convenient for the user to use and minimizes interference between the various components.

[0018] However, the limitations of existing body care devices make it impossible to adequately address this issue. Utility Model Content

[0126] The body care device 1000 provided in the embodiments of this utility model may include a seat drive unit 500, a backrest drive unit 600, a canopy drive unit 700, and a control unit 800.

[0127] The seat drive unit 500 is a structure provided on the main frame 110 and that moves the seat frame 210 in the front-back direction.

[0128] The backrest drive unit 600 is a structure that is provided on the seat frame 210 and causes the backrest frame 310 to rotate about the frame axis 311.

[0129] The canopy drive unit 700 is a structure that connects the main frame 110 and the canopy 400 and drives the canopy 400 to rotate relative to the main frame 110.

[0130] The control unit 800 can control the seat drive unit 500, the backrest drive unit 600, and the canopy drive unit 700.

[0131] The body care device 1000 may include various sensors. When a user sits on the seat 200, the sensors can detect the user. The control unit 800 can receive the signals from the sensors and start automatic operation.

[0132] When a user sits on the seat 200, various sensors can measure body temperature, body fat percentage, pulse, blood pressure, etc. The control unit 800 can receive signals from various sensors to diagnose the user's health status and adjust the massage mode or intensity accordingly.

[0133] The body care device 1000 may include a remote control. The remote control can send signals to the control unit 800. The user can operate the remote control to finely set / control massage actions, massage range, massage position, massage speed, massage intensity, etc.

[0134] The main cover 120 may include a first magnetic component. The remote control may include a second magnetic component. The first magnetic component may include a permanent magnet. The second magnetic component may include a permanent magnet or a strong magnet. The remote control can be attached to the main cover 120 by the magnetic force of the first and second magnetic components. The first magnetic component may be located on or around the armrest.

[0135] Figure 8 yes Figure 3 A cross-sectional view of the body care device 1000, showing the seat drive unit 500.

[0136] Figure 9 yes Figure 3 A cross-sectional view of the body care device 1000, showing the backrest drive unit 600.

[0137] Figure 8 as well as Figure 9 This diagram shows the seat 200 and backrest 300 in a first position. The first position can be represented by the backrest 300 being upright. The user can sit on the body care device 1000 in this first position. The user can receive body care in this first position.

[0138] The seat drive unit 500 can be rotatably attached to the first a portion 501 of the main frame 110 and the second a portion 502 of the seat frame 210. The seat drive unit 500 is composed of a linear actuator that extends and retracts between the first a portion 501 and the second a portion 502.

[0139] The seat drive unit 500 can be composed of a linear motor, which extends a rotary AC motor into a straight line. Alternatively, the seat drive unit 500 can be configured to use a rotary motor and a rack and pinion mechanism.

[0140] The seat drive unit 500 may include a fixed part and a movable part. The movable part can move linearly with respect to the fixed part.

[0141] The fixing part can be rotatably connected to the first a portion 501 of the main frame 110 via a cylindrical shaft. The first a portion 501 can be located on the upper rear side of the base 111. The longitudinal direction of the cylindrical shaft can be parallel to the X-axis.

[0142] The movable part can be rotatably attached to the second a portion 502 of the seat frame 210 via a cylindrical shaft. The second a portion 502 can be located on the lower front side of the seat frame 210. The longitudinal direction of the cylindrical shaft can be parallel to the X-axis.

[0143] Figure 10 This is a cross-sectional view of the body care device 1000 provided in an embodiment of the present invention, showing the seat 200 and backrest 300 in a second posture.

[0144] The second posture can be described as lying down with the backrest at 300 degrees. The user can lie on the body care device 1000 in the second posture. The user can receive body care in the second posture.

[0145] As the movable part moves linearly with the fixed part as a reference, the seat drive unit 500 can push the seat frame 210 forward or pull it backward. At this time, the first roller 231a and the second roller 231b can travel in the front-back direction along the travel surface 113 on the left and right sides of the main frame 110. Therefore, the seat part 200 can travel in the front-back direction.

[0146] At this time, the guide surface 117 can be positioned opposite one surface of the guide disk 233 on the left and right sides of the main frame 110 in the left-right direction with a small interval (see reference). Figure 5 ).

[0147] Therefore, when the first roller 231a and the second roller 231b travel along the travel surface 113 in the front-to-back direction on the left and right sides of the main frame 110, the movement of the first roller 231a and the second roller 231b in the left-to-right direction can be blocked. Therefore, the movement and rotation of the seat part 200 in the left-to-right direction can be blocked.

[0148] Figure 11 It is shown Figure 4 The side view of the roller 231 placed on the travel surface 113 is a diagram showing the state of the second roller 231b located at the rear end portion S2 of the travel interval S.

[0149] Figure 12 It is shown Figure 4 The side view of the first roller 231a placed on the travel surface 113 is a diagram showing the first roller 231a located at the front end S1 of the travel interval S.

[0150] The guide member 112 may be formed with a movement range S for the moving member 230 to move in the front-back direction. The movement range S may represent the path or space in which the first roller 231a and the second roller 231b move.

[0151] The rear end portion S2 of the moving section S can represent the location or space where the second roller 231b is located in the first posture. The rear end portion S2 of the traveling surface 113 can represent the location where the second roller 231b is located in the first posture. The rear end portion S2 of the moving section S and the rear end portion S2 of the traveling surface 113 can be used with the same meaning. The front end portion S1 of the moving section S can represent the location or space where the first roller 231a is located in the second posture. The front end portion S1 of the traveling surface 113 can represent the location where the first roller 231a is located in the second posture. The front end portion S1 of the moving section S and the front end portion S1 of the traveling surface 113 can be used with the same meaning.

[0152] As the seat drive unit 500 extends and retracts between the first a portion 501 and the second a portion 502, the first roller 231a and the second roller 231b can move in the forward and backward direction within the movement range S.

[0153] The control unit 800 can control the seat drive unit 500, causing the posture of the seat unit 200 to change from a first posture to a second posture and from a second posture to a first posture.

[0154] When the second roller 231b is located at the rear end S2 of the moving section S (refer to...) Figure 11 The seat 200 can be in the first position (see reference). Figure 9 The first posture can be represented by the backrest 300 being raised. The user can sit on the body care device 1000 in the first posture. The user can receive body care in the first posture.

[0155] When the first roller 231a is located at the front end S1 of the moving section S (refer to...) Figure 12 The seat 200 can be in a second position (see reference). Figure 10 The second posture can be described as lying down with the backrest at 300 degrees. The user can lie on the body care device 1000 in this second posture and receive body care.

[0156] The guide 112 may incorporate a front boundary component 115 and a rear boundary component 116.

[0157] The front boundary component 115 can engage with the guide 112 at a position forward of the front end S1 of the moving section S. The front boundary component 115 can prevent the first roller 231a from falling off to the front of the moving section S.

[0158] The rear boundary component 116 can engage with the guide 112 at a position further rear than the rear end portion S2 of the movement section S. The rear boundary component 116 can prevent the second roller 231b from falling off to the rear side of the movement section S.

[0159] The guide member 112 may include a traveling upper surface 114. The traveling upper surface 114 may form the upper surface of the moving section S. The traveling surface 113 may form the bottom surface of the moving section S. The roller 231 may be placed on the traveling surface 113 and spaced apart from the traveling upper surface 114 by a small interval (see reference). Figure 5 ).

[0160] Therefore, even if the user sitting on the seat 200 moves their body or the seat 200 is subjected to external force, the vertical movement of the first roller 231a and the second roller 231b can be prevented. Thus, the vertical movement and rotation of the seat 200 can be prevented.

[0161] The first roller 231a can be rotatably attached to the seat frame 210. The second roller 231b can be rotatably attached to the seat frame 210 at a position further rear than the first roller 231a. Therefore, the straight line connecting the central axis of the first roller 231a and the central axis of the second roller 231b (hereinafter referred to as the "axis connection line CL") can rotate integrally with the seat frame 210.

[0162] The seat cover 220 can be combined with the seat frame 210. The seat cover 220 can be formed with a first mounting surface 221. The first mounting surface 221 may include a hip mounting surface 221a. Therefore, the axis connecting line CL can rotate integrally with the hip mounting surface 221a.

[0163] In the first posture of the seat section 200, the second roller 231b can be positioned lower than the first roller 231a. Therefore, in the first posture, the axis connecting line CL can form an angle of less than 0° with the Y-axis centered on the central axis of the first roller 231a (see reference). Figure 11 As an example, in the first posture, the axis connecting line CL can form an angle of -7° with the Y-axis. The reference numeral '-' can indicate a backward tilt.

[0164] The user can sit on the body care device 1000 in a first posture. The user can receive body care in the first posture. The axis connecting line CL can be parallel to the buttocks mounting surface 221a. Therefore, in the first posture, the buttocks mounting surface 221a can form an angle of less than 0° (for example, -7°) with the Y-axis (see reference). Figure 8 Therefore, the buttocks-supporting surface 221a can slope backward. Thus, the weight of the user sitting on the seat 200 in the first posture can be distributed between the seat 200 and the backrest 300, rather than concentrated on the seat 200. Therefore, a comfortable seating experience can be provided to the user sitting on the seat 200 in the first posture.

[0165] The moving section S can be formed as a curve with varying height in the front-to-back direction. The traveling surface 113 can be formed as a curved surface with different heights in the front-to-back direction. Therefore, when the posture of the seat 200 changes from a first posture to a second posture and from a second posture to a first posture, the angle of the buttocks resting surface 221a can be smoothly changed as the first roller 231a and the second roller 231b travel along the curved surface. Therefore, a comfortable seating experience can be provided to the user sitting on the seat 200.

[0166] The travel surface 113 can be formed as a curved surface that convexes upwards based on the rear-to-rear direction. Therefore, the angle between the buttocks resting surface 221a and the horizontal plane can be reduced as the moving member 230 moves from the rear end portion S2 to the front end portion S1 of the travel interval S. Conversely, the angle between the buttocks resting surface 221a and the horizontal plane can be increased as the moving member 230 moves from the front end portion S1 to the rear end portion S2 of the travel interval S. That is, when the posture of the seat portion 200 changes from the first posture to the second posture and from the second posture to the first posture, the buttocks resting surface 221a can smoothly rotate to both sides as the first roller 231a and the second roller 231b travel along the curved surface (curved shape). Therefore, a comfortable seating experience can be provided to the user sitting on the seat portion 200.

[0167] The travel surface 113 can form a certain curvature based on the back-to-back direction. Therefore, the moving speed and rotational speed of the seat section 200 can be proportional. Thus, when the posture of the seat section 200 changes from a first posture to a second posture and from a second posture to a first posture, as the first roller 231a and the second roller 231b travel along the curved surface (curve) at a certain speed, the buttocks-supporting surface 221a can rotate smoothly at a certain angular velocity. Therefore, a comfortable seating experience can be provided to the user sitting on the seat section 200.

[0168] The highest point S3 of the moving section S can be located between the front end S1 and the rear end S2 of the moving section S. Similarly, the highest point S3 of the traveling surface 113 can be located between the front end S1 and the rear end S2 of the traveling surface 113. Therefore, the first roller 231a can be located forward of the highest point S3 of the traveling surface 113 or the moving section S, and the second roller 231b can be located backward of the highest point S3 of the traveling surface 113 or the moving section S. At this time, the central axis of the first roller 231a and the central axis of the second roller 231b can reach the same height, and the axis connection line CL can form a 0° angle with the Y-axis (see reference). Figure 10 At this time, the seat portion 200 can assume a second posture. Therefore, when the posture of the seat portion 200 changes from the first posture to the second posture and from the second posture to the first posture, the angle between the buttocks mounting surface 221a and the Y-axis can rotate smoothly between less than 0° (for example, -7°) and 0°. Therefore, a comfortable seating experience can be provided to the user sitting on the seat portion 200.

[0169] The highest point S3 of the moving section S can be closer to the front point S1 of the moving section S than the rear end S2 of the moving section S. The highest point S3 of the traveling surface 113 can be closer to the front point S1 of the traveling surface 113 than the rear end S2 of the traveling surface 113. Therefore, as the second roller 231b moves towards the rear end S2 of the moving section S, the axis connecting line CL can form an angle of less than 0° with the Y-axis (refer to...). Figure 11 Furthermore, as the first roller 231a moves towards the front end S1 of the moving section S, the axis connecting line CL can form a 0° angle with the Y-axis (see reference). Figure 12 Therefore, it is possible to miniaturize the moving section S and the longitudinal length of the traveling surface 113. Therefore, it is possible to miniaturize the longitudinal length of the guide member 112.

[0170] The rear end S2 of the moving section S can be lower than the front end S1 of the moving section S. Therefore, even if the traveling surface 113 has a certain curvature, the highest point S3 of the moving section S can be closer to the front end S1 of the moving section S than the rear end S2. Therefore, even if the traveling surface 113 has a certain curvature, as the second roller 231b moves towards the rear end S2 of the moving section S, the axis connecting line CL can form an angle of less than 0° with the Y-axis (see reference). Figure 11 Furthermore, as the first roller 231a moves towards the front end S1 of the moving section S, the axis connecting line CL can also form a 0° angle with the Y-axis (see reference). Figure 12 Therefore, even if the traveling surface 113 has a certain curvature, the length of the guide member 112 in the front-to-back direction can be miniaturized.

[0171] The backrest drive unit 600 can be rotatably coupled to the first b portion 601 of the seat frame 210 and the second b portion 602 of the backrest frame 310. The backrest drive unit 600 is composed of a linear actuator that extends and retracts between the first b portion 601 and the second b portion 602.

[0172] The backrest drive unit 600 can be composed of a linear motor, which extends a rotary AC motor into a straight line. Alternatively, the backrest drive unit 600 can be configured to use a rotary motor and a rack and pinion mechanism.

[0173] The backrest drive unit 600 may include a fixed part and a movable part. The movable part can move linearly with respect to the fixed part.

[0174] The fixing part can be rotatably connected to the first b portion 601 of the seat frame 210 via a cylindrical shaft. The first b portion 601 can be located at the lower front side of the seat frame 210. The longitudinal direction of the cylindrical shaft can be parallel to the X-axis.

[0175] The movable part can be rotatably connected to the second b portion 602 of the backrest frame 310 via a cylindrical shaft. The second b portion 602 can be located at the lower rear side of the backrest frame 310. The second b portion 602 can be located at a position further rearward than the frame shaft 311. The longitudinal direction of the cylindrical shaft can be parallel to the X-axis.

[0176] As the movable part moves linearly about the fixed part, the second b portion 602 can rotate about the frame axis 311. Therefore, as the movable part moves linearly about the fixed part, the backrest drive unit 600 can rotate the backrest frame 310 about the frame axis 311. That is, as the backrest drive unit 600 extends and retracts between the first b portion 601 and the second b portion 602, the backrest frame 310 can be raised forward (see reference). Figure 9 Or lie back (see reference) Figure 10 ).

[0177] The control unit 800 can synchronously control the seat drive unit 500 and the backrest drive unit 600, so that the posture of the seat 200 and the backrest 300 changes from a first posture to a second posture and then back from a second posture to a first posture.

[0178] The control unit 800 can synchronously control the seat drive unit 500 and the backrest drive unit 600, so that when the seat frame 210 moves forward, the backrest frame 310 reclines backward (see reference). Figure 10 When the seat frame 210 moves backward, the backrest frame 310 is raised (see reference). Figure 9 ).

[0179] In the first posture, the second mounting surface 321 of the backrest 300 can tilt backward (see reference). Figure 9 As an example, in the first posture, the second mounting surface 321 of the backrest 300 can tilt backward at an angle of approximately +60° to the Y-axis. The reference numeral '+' indicates forward tilt. In the first posture, the buttocks mounting surface 221a can form an angle of less than 0° (for example, -7°) with the Y-axis. Therefore, in the first posture, the buttocks mounting surface 221a can slope backward, and the second mounting surface 321 can tilt backward. The user can sit on the body care device 1000 in the first posture. The user can receive body care in the first posture. In the first posture, the angle between the buttocks mounting surface 221a and the second mounting surface 321 can be slightly greater than 90°. For example, in the first posture, the buttocks mounting surface 221a and the second mounting surface 321 can form an angle of approximately 110°. Therefore, the weight of a user sitting on the seat 200 in the first posture can be distributed between the seat 200 and the backrest 300, rather than concentrated on the seat 200. Thus, a comfortable seating experience can be provided to the user sitting on the seat 200 in the first posture.

[0180] In the second posture, the second mounting surface 321 of the backrest 300 can form a 0° angle with the Y-axis (see reference). Figure 10 In the second posture, the buttocks mounting surface 221a can form a 0° angle with the Y-axis. Therefore, in the second posture, the buttocks mounting surface 221a and the second mounting surface 321 can form a 0° angle with the Y-axis. In the second posture, the buttocks mounting surface 221a and the second mounting surface 321 can be on the same plane. The user can lie on the body care device 1000 in the second posture. The user can receive body care in the second posture. Therefore, a comfortable seating experience can be provided to the user lying on the first mounting surface 221 and the second mounting surface 321 in the second posture.

[0181] When the posture of the backrest 300 changes from a first posture to a second posture and back to a first posture, the angle between the second mounting surface 321 and the Y-axis can smoothly rotate between approximately +60° and 0°. When the posture of the seat 200 changes from a first posture to a second posture and back to a first posture, the angle between the buttock mounting surface 221a and the Y-axis can smoothly rotate between less than 0° (for example, -7°) and 0°. Therefore, except for the second posture, the buttock mounting surface 221a can always form a downward slope to the rear. Therefore, when the postures of the seat 200 and the backrest 300 change from a first posture to a second posture and back to a first posture, the user's weight can be distributed between the seat 200 and the backrest 300, rather than concentrated on the seat 200. Therefore, when the postures of the seat 200 and the backrest 300 change from a first posture to a second posture and back to a first posture, a comfortable seating experience can be provided to the user.

[0182] When the posture of the seat 200 and backrest 300 changes from a first posture to a second posture, the seat 200 can move forward via the seat drive 500. The control unit 800 can simultaneously control the seat drive 500 and the backrest drive 600 so that the rear end of the backrest 300 does not move backward when the posture of the seat 200 and backrest 300 changes from the first posture to the second posture. Alternatively, the control unit can simultaneously control the seat drive 500 and the backrest drive 600 so that the rear end of the backrest 300 moves backward only within an allowable distance when the posture of the seat 200 and backrest 300 changes from the first posture to the second posture. Here, the allowable distance can represent the distance at which the rear end of the backrest 300 does not contact an object behind the backrest 300, such as the canopy 400. Therefore, when the posture of the seat 200 and backrest 300 changes from the first posture to the second posture, the backrest 300 can be prevented from contacting the canopy 400. Therefore, regardless of whether there is any space behind the backrest, you can recline.

[0183] Figure 13 This is a diagram showing the state in which the canopy drive unit 700 is provided in the body care device 1000 provided in an embodiment of the present invention. Figure 14 It is shown Figure 13 A diagram of the main frame 110, seat frame 210, backrest frame 310, canopy 400, and canopy drive unit 700 in the body care device 1000. Figure 15 To show in more detail Figure 13 The figure shows the canopy drive unit 700 in the body care device 1000. Figures 16 to 19 This is a diagram illustrating the driving process of the canopy 400 in the body care device 1000 provided in an embodiment of the present invention.

[0184] The body care device 1000 provided in the embodiment of this utility model includes a main frame 110, a seat frame 210, a backrest frame 310, a canopy 400, and a canopy drive unit 700. In this case, when the canopy drive unit 700 drives the canopy 400 to rotate, it moves the canopy 400 in the front-rear direction of the main frame 110.

[0185] Here, the "front direction" refers to the facing direction of the user seated on the body care device 1000, which can be the direction indicated by the Y-axis arrow in the attached drawing. Conversely, the "rear direction" refers to the facing direction of the user seated on the body care device 1000, which can be the side opposite to the direction indicated by the Y-axis arrow in the attached drawing.

[0186] Therefore, the front and back directions of the main frame 110, as the front and back directions of the user seated on the body care device 1000, can be along the Y-axis in the attached drawings.

[0187] The main frame 110 is the skeleton that forms the main body 100 and can support the seat 200, backrest 300 and canopy 400 relative to the ground.

[0188] The seat frame 210 is the skeleton that forms the seat part 200 and can be set on the main frame 110 to support the user's buttocks.

[0189] The backrest frame 310 is part of the skeleton that forms the backrest 300. One end (312) of the backrest frame 310 can be combined with the seat frame 210 to support the user's back.

[0190] The canopy 400 is configured to be rotated relative to the main frame 110 and to cover one side of the other end 313 of the backrest frame 310 as it is rotated. This canopy 400 can be unfolded to cover the face of the seated user as needed.

[0191] The canopy drive unit 700 is a part that connects the main frame 110 and the canopy 400 and drives the canopy 400 to rotate relative to the main frame 110. The canopy 400 can be driven by the canopy drive unit 700 without the user having to drive the canopy 400 himself when a drive signal is input.

[0192] In this way, the user of the body care device 1000 can drive the canopy 400 through the canopy drive unit 700 to cover the face as needed, thus preventing bright lights from the ceiling from interfering with sleep and rest.

[0193] However, if the rotation of the canopy 400 is driven by a simple hinge rotation, the rotating canopy 400 may collide with the user's head.

[0194] Therefore, the body care device 1000 provided in this embodiment is configured such that the canopy 400 is rotated while moving in the front-rear direction of the main frame 110, thereby preventing the collision as described above.

[0195] In this way, in the body care device 1000 provided in the embodiment of the present invention, when the canopy 400 is rotated relative to the main frame 110, the canopy 400 moves in the front-rear direction of the main frame 110, thus preventing the rotated canopy 400 from colliding with the user's head, thereby enabling the body care device 1000 to be used more conveniently and smoothly.

[0196] In the body care device 1000 provided in the embodiments of this utility model, the canopy drive unit 700 may include a first canopy link 710, a second canopy link 720 and a third canopy link 730.

[0197] The first canopy link 710 is the part that is hinged to the central part and the first link hinge axis 701. The first canopy link 710 can rotate hingedly around the first link hinge axis 701, wherein the first link hinge axis 701 is formed laterally on the main frame 110.

[0198] The second canopy link 720 is a part in which one end 721 is hinged to the second link hinge shaft 702 and the other end 722 is connected to the canopy 400. The second link hinge shaft 702 is formed side by side with the first link hinge shaft 701 at one end 711 of the first canopy link 710.

[0199] Therefore, when the first canopy link 710 rotates by hinge, one end 721 of the second canopy link 720, which is connected to one end 711 of the first canopy link 710, moves together, thereby enabling the canopy 400, which is connected to the other end 722 of the second canopy link 720, to move. In this case, the second canopy link 720 can rotate by hinge about the second link hinge axis 702.

[0200] The third canopy link 730 is a part in which one end 731 is hinged to the third link hinge shaft 703 and the other end 732 is hinged to the fourth link hinge shaft 704. The third link hinge shaft 703 is formed side by side with the first link hinge shaft 701 in the central part of the second canopy link 720, and the fourth link hinge shaft 704 is formed side by side with the first link hinge shaft 701 in the main frame 110.

[0201] Therefore, when the second canopy link 720 moves, its central portion can move within a range constrained by the third canopy link 730. In this case, the third canopy link 730 can hinge and rotate about the third link hinge axis 703 and the fourth link hinge axis 704.

[0202] The following is for reference Figures 16 to 19 The process of driving the canopy 400 through the canopy drive unit 700 will be explained.

[0203] First, such as Figure 16 As shown, when the canopy 400 is not needed, the first canopy link 710, the second canopy link 720, and the third canopy link 730 can remain in a state of no additional operation when they are connected together.

[0204] Secondly, in the case of user-driven canopy 400, such as Figure 17 As shown, the first canopy link 710 is hinged to rotate about the first link hinge axis 701. As a result, one end 711 of the first canopy link 710 moves rearward, and the second canopy link 720 and the canopy 400, which are connected to one end 711 of the first canopy link 710, also move rearward.

[0205] In this case, since the central part of the second canopy link 720 is hinged to one end 731 of the third canopy link 730, the central part of the second canopy link 720 moves along the rotation radius of the third canopy link 730.

[0206] Secondly, such as Figure 18 As shown, the canopy 400 moves backward until the second canopy link 720 moves to the rearmost position through the additional rotation of the first canopy link 710.

[0207] Secondly, such as Figure 19 As shown, when the first canopy link 710 is further rotated, one end 721 of the second canopy link 720 moves downward. In this case, since the central part of the second canopy link 720 is hinged to one end 731 of the third canopy link 730, the second canopy link 720 is tilted at an angle, and the canopy 400, which is connected to the other end 722 of the second canopy link 720, is rotated.

[0208] Through the driving process described above, the canopy 400 can simultaneously complete forward and backward movement and rotation, and the structure of the canopy drive unit 700 that drives the canopy 400 can be constructed relatively simply and efficiently.

[0209] In this way, in the body care device 1000 provided in the embodiment of the present invention, the canopy drive unit 700 that drives the canopy 400 is configured to include a first canopy link 710, a second canopy link 720 and a third canopy link 730. Therefore, the canopy drive unit 700 can reduce workload and time, and occupy less installation space, thereby optimizing the functionality and usability of the body care device 1000.

[0210] In the body care device 1000 provided in the embodiment of this utility model, the canopy drive unit 700 may further include a canopy actuator 740, which is connected to the other end 712 of the first canopy link 710, so that the first canopy link 710 rotates about the first link hinge axis 701.

[0211] In this case, the canopy actuator 740 can be configured as a length-extendable linear actuator for the portion that engages with the other end 712 of the first canopy link 710.

[0212] Therefore, as Figures 16 to 19 As shown, when the length of the canopy actuator 740 is shortened, the first canopy link 710 can be rotated to drive the canopy 400. Conversely, when the length of the canopy actuator 740 is extended again, the first canopy link 710 can be rotated in the opposite direction to return the canopy 400 to its original position.

[0213] On the other hand, the roof actuator 740 can be a linear motor that extends a rotary AC motor into a straight line. Alternatively, the roof actuator 740 can be configured to use a rotary motor and a rack and pinion mechanism.

[0214] In this way, the body care device 1000 provided by the embodiment of the present invention completes the operation of the canopy drive unit 700 through the canopy actuator 740, and thus can automatically and accurately drive the canopy 400.

[0215] In the body care device 1000 provided in the embodiments of this utility model, the canopy actuator 740 can be hinged to the main frame 110 and the first canopy link 710 respectively.

[0216] As described above, when the canopy actuator 740, which is engaged with the other end 712 of the first canopy link 710, causes the first canopy link 710 to rotate hingedly, it is possible to change the engagement angle between the other end 712 of the first canopy link 710 and the canopy actuator 740.

[0217] To counteract the changing engagement angle, the configuration angle of the canopy actuator 740 can preferably be made not fixed, but appropriately changed as the first canopy link 710 rotates.

[0218] Therefore, by hingedly connecting the canopy actuator 740 to the main frame 110 and the first canopy link 710 respectively, the configuration angle of the canopy actuator 740 can be appropriately changed as the first canopy link 710 rotates.

[0219] In this way, the body care device 1000 provided by the embodiment of the present invention is configured to achieve hinge rotation by the canopy actuator 740, so that the other end 712 of the first canopy link 710, whose position changes when the hinge rotates, can be smoothly driven.

[0220] In the body care device 1000 provided in the embodiments of this utility model, the first canopy link 710 can be formed by bending around the first link hinge axis 701. That is, the first canopy link 710 can be composed of a single component that extends at different angles to both ends around the first link hinge axis 701.

[0221] As described above, the first canopy link 710 can be a structure for moving the second canopy link 720 and the canopy 400 when the hinge is rotated.

[0222] In this case, if the first canopy link 710 is formed as a straight line, the radius of rotation becomes relatively large, which may occupy a large installation space. As a result, when the first canopy link 710 is formed by multiple interconnected parts, the structure becomes relatively complex, and there may be stress-vulnerable parts in the drive force transmission structure.

[0223] Therefore, the problem described above can be solved by forming the first canopy link 710 from a single component and bending it around the first link hinge axis 701.

[0224] In this way, in the body care device 1000 provided in the embodiment of the present invention, the first canopy link 710 hinges and rotates around the bent portion, so even if the first canopy link 710 is composed of a single component, the direction of the driving force transmitted through the hinge rotation of the first canopy link 710 can be effectively changed.

[0225] In the body care device 1000 provided in the embodiments of this utility model, the second canopy link 720 can be formed by bending around the third link hinge axis 703. That is, the second canopy link 720 can be composed of a single component that extends at different angles to both ends around the third link hinge axis 703.

[0226] As described above, the second canopy link 720 may be a structure for moving in the front-to-back direction as the hinge of the first canopy link 710 rotates, and for driving the canopy 400 to rotate while changing the configuration angle.

[0227] In this case, if the second canopy link 720 is formed as a straight line, a relatively large change in the configuration angle is required to enable the canopy 400 to rotate significantly, which may occupy a large installation space. Therefore, when the second canopy link 720 is formed by multiple interconnected parts, the structure becomes relatively complex, and there may be stress-vulnerable parts in the drive force transmission structure.

[0228] Therefore, the problem described above can be solved by forming the second canopy link 720 from a single component and bending it around the third link hinge axis 703.

[0229] In this way, in the body care device 1000 provided in the embodiment of the present invention, even if the second canopy link 720 is composed of a single component, the direction of the driving force transmitted by the hinge rotation of the second canopy link 720 can be effectively changed.

[0230] In the body care device 1000 provided in the embodiments of this utility model, the first canopy link 710 can be bent so that one end 711 is positioned relative to the rear side of the extension line, which is the line connecting the central portion from the other end 712. In this case, the second canopy link 720 can be bent so that the other end 722 is positioned relative to the front side of the extension line, which is the line connecting the central portion from one end 721.

[0231] That is, such as Figure 15 As shown, the extension line connecting the other end 712 of the first canopy link 710 to the central part can be configured at a position relative to the front side than one end 711 of the first canopy link 710.

[0232] Therefore, compared with the hinge rotation angle of the first canopy link 710, the distance that one end 711 of the first canopy link 710 can be moved backward can be relatively increased. That is, even if the rotation angle of the first canopy link 710 is relatively small, the second canopy link 720 and the canopy 400 can be moved significantly in the front-back direction.

[0233] In addition, such as Figure 15 As shown, the extension line connecting one end 721 of the second canopy link 720 to the central part can be configured at a position relative to the rear side of the other end 722 of the second canopy link 720.

[0234] Therefore, compared to the degree to which the second canopy link 720 is tilted, the degree of tilt of the other end 722 of the second canopy link 720 can be relatively increased. That is, even if the degree of tilt of the second canopy link 720 is relatively small, the rotation angle of the canopy 400 connected to the other end 722 of the second canopy link 720 can be increased.

[0235] In this way, the body care device 1000 provided by the embodiment of the present invention is configured such that the bending direction of the first canopy link 710 and the second canopy link 720 is optimized to drive the canopy 400. Therefore, even if a relatively small displacement occurs in the canopy actuator 740, the canopy 400 can be driven effectively.

[0236] Figures 20 to 22 This is a diagram illustrating the driving process of the backrest frame 310 and canopy 400 in the body care device 1000 provided by an embodiment of the present invention.

[0237] The body care device 1000 provided in the embodiments of this utility model may further include a main cover 120 covering the main frame 110, the seat frame 210, and the backrest frame 310. In this case, the canopy 400 may be detachably combined with the main cover 120.

[0238] Specifically, the main body cover 120 can be configured to cover the front surface, rear surface, and sides of the main body frame 110. The main body cover 120 can prevent the main body frame 110 from being exposed to the outside due to the front surface, rear surface, and sides of the main body 100.

[0239] like Figure 20 As shown, the main body cover 120 can be combined with the canopy 400 to form a unified appearance. Additionally, when the canopy 400 is required, such as... Figure 21 as well as Figure 22 As shown, the canopy 400 can be detached from the main cover 120 and driven to cover the face of the seated user.

[0240] In this way, in the body care device 1000 provided in the embodiment of the present invention, the canopy 400 is detachably combined with the main body cover 120 that constitutes the main appearance, so the canopy 400 combined with the main body cover 120 can bring a sense of unity and improve the design effect of the appearance.

[0241] In the body care device 1000 provided in the embodiment of this utility model, when the canopy 400 is not separated from the main body cover 120, the uppermost end of the canopy 400 can be located on the opposite rear side of the other end 313 of the backrest frame 310.

[0242] That is, such as Figure 20 As shown, when the canopy 400 is not needed, the top of the canopy 400 can be configured such that it is positioned on the opposite rear side of the other end 313 of the backrest frame 310.

[0243] Since the user's face is located on the other end 313 side of the backrest frame 310, the canopy 400 does not need to cover the other end 313 side of the backrest frame 310 when the canopy 400 is not needed.

[0244] Conversely, the closer the canopy 400 is to the other end 313 of the backrest frame 310, the more likely the user's head is to collide with the canopy 400. Therefore, it is preferable to position the uppermost part of the canopy 400 relative to the rear side of the other end 313 of the backrest frame 310.

[0245] In this way, in the body care device 1000 provided in the embodiment of the present invention, when the main body cover 120 and the canopy 400 are not separated, the uppermost end of the canopy 400 is located on the opposite rear side of the other end 313 of the backrest frame 310. Therefore, when it is not necessary to cover the face of the seated user, it is possible to prevent the canopy 400 from interfering with the user's head or other main components.

[0246] In the body care device 1000 provided in the embodiment of this utility model, when the canopy 400 is separated from the main body cover 120 and is rotated, the uppermost end of the canopy 400 can be located on the opposite front side of the other end 313 of the backrest frame 310.

[0247] That is, such as Figure 22 As shown, when the canopy 400 is rotated for use, it can be configured such that the uppermost end of the canopy 400 is located on the opposite front side of the other end 313 of the backrest frame 310.

[0248] Given that the user's face is located on the other end 313 side of the backrest frame 310, the canopy 400 needs to cover the other end 313 side of the backrest frame 310 when the canopy 400 is required.

[0249] Therefore, the uppermost part of the canopy 400 can be preferably positioned relative to the front side of the other end 313 of the backrest frame 310, so as to cover more of the user's face on the other end 313 side of the backrest frame 310.

[0250] In this way, in the body care device 1000 provided in the embodiment of the present invention, when the canopy 400, which is separated from the main body cover 120, is rotated, the uppermost end of the canopy 400 is located on the opposite front side of the other end 313 of the backrest frame 310, so the canopy 400 can more effectively cover the face of the seated user when needed.

[0251] The body care device 1000 provided in the embodiments of this utility model may further include a backrest drive unit 600 that drives the backrest frame 310 to rotate relative to the seat frame 210.

[0252] That is, the backrest frame 310 can be combined with the seat frame 210 in a way that allows it to be rotated around the frame axis 311 and stand up or recline, and the backrest frame 310 can be driven by the backrest drive unit 600.

[0253] Thus, users can use the body care device 1000 while adjusting the angle of the backrest frame 310 according to their preferences and circumstances.

[0254] In the body care device 1000 provided in the embodiment of this utility model, the backrest drive unit 600 can drive the backrest frame 310 to rotate while the canopy 400 is moving behind the main frame 110.

[0255] This effectively prevents the backrest frame 310 from colliding with the canopy 400 during the rotational drive process.

[0256] In the body care device 1000 provided in the embodiment of this utility model, the canopy drive unit 700 can rotate the canopy 400 while the backrest frame 310 is being rotated.

[0257] This effectively prevents the canopy 400 from colliding with the backrest frame 310 during the rotational drive process.

[0258] The body care device 1000 provided in the embodiment of this utility model includes a main frame 110, a seat frame 210, a backrest frame 310, a backrest drive unit 600, a canopy 400, a canopy drive unit 700, and a control unit 800. In this case, the control unit 800 controls the backrest drive unit 600 and the canopy drive unit 700 to work sequentially.

[0259] That is, the backrest drive unit 600 and the canopy drive unit 700 can work in different ways, but can work together to form alternating steps in a certain order.

[0260] If the backrest drive unit 600 and the canopy drive unit 700 operate simultaneously, it may cause the backrest frame 310 to collide with the canopy 400 during the reclining process, or the canopy 400 to collide with the backrest frame 310 during the rotational drive process.

[0261] Therefore, it is preferable to control the backrest frame 310 and the canopy 400 sequentially so that they do not interfere with each other.

[0262] In this way, in the body care device 1000 provided in the embodiment of the present invention, the canopy drive 700 that drives the canopy 400 and the backrest drive 600 that drives the backrest frame 310 work together in a coordinated manner, so that interference between the rotation drive of the canopy 400 and the rotation drive of the backrest frame 310 can be avoided, and the various components of the body care device 1000 can work smoothly.

[0263] In the body care device 1000 provided in the embodiment of this utility model, the control unit 800 can control the canopy drive unit 700 so that when the canopy 400 is rotated, the canopy 400 moves in the front-rear direction of the main frame 110.

[0264] This prevents the rotating canopy 400 from colliding with the user's head, making the use of the body care device 1000 more convenient and smoother.

[0265] In the body care device 1000 provided in the embodiment of this utility model, the control unit 800 can control the backrest drive unit 600 and the canopy drive unit 700 so that the backrest frame 310 is rotated while the canopy 400 is moving behind the main frame 110.

[0266] That is, such as Figure 20 as well as Figure 21 As shown, the canopy 400 can move behind the main frame 110 before the backrest frame 310 rotates. By rotating the backrest frame 310 in this state, interference between the rotating backrest frame 310 and the canopy 400 can be prevented.

[0267] In this way, in the body care device 1000 provided in the embodiment of the present invention, the backrest frame 310 is rotated while the canopy 400 is moving behind the main frame 110, thereby effectively preventing the backrest frame 310 from colliding with the canopy 400 during the rotation process.

[0268] In the body care device 1000 provided in the embodiment of this utility model, the control unit 800 can control the backrest drive unit 600 and the canopy drive unit 700, so that the canopy 400 is rotated while the backrest frame 310 is being rotated.

[0269] That is, such as Figure 21 as well as Figure 22 As shown, the backrest frame 310 can be rotated while the canopy 400 is moving rearward, before the canopy 400 is rotated. In this way, by rotating the canopy 400 while the backrest frame 310 is being rotated, interference between the rotating canopy 400 and the backrest frame 310 can be prevented.

[0270] In this way, in the body care device 1000 provided in the embodiment of the present invention, the canopy 400 is rotated while the backrest frame 310 is being rotated, thus effectively preventing the canopy 400 from colliding with the backrest frame 310 during the rotation process.

[0271] The specific embodiments of this utility model have been described and illustrated above. However, this utility model is not limited to the described embodiments. It will be obvious to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of this utility model. Therefore, such modifications or variations should not be understood separately from the technical concept or viewpoint of this utility model, and the modified embodiments should fall within the scope of the claims of this utility model.
