The back cover part (400) may be configured as a separate part from the light irradiator (10), constitute a part of the body massage part (1000), and may be formed integrally with the body massage part (1000).

[0137] In this case, various modifications are possible, such as the mount part (100) being directly connected to the back cover part (400) formed integrally with the body massage part (1000).

[0138] Hereinafter, the back cover part (400) will be described in detail based on the fact that it is a component of the light irradiator (10) and is detachably connected to one side, specifically the upper rear side, of the body massage part (1000).

[0139] A light irradiator (10) according to one embodiment of the present invention can provide a user with low level laser therapy (LLLT) that irradiates light of a specific wavelength to the scalp or face to promote metabolism in the relevant area and activate tissue function.

Fig. 7 is a perspective view illustrating a mount portion (100) according to one embodiment of the present invention. Fig. 8 is an exploded perspective view illustrating a mount portion (100) according to one embodiment of the present invention. Fig. 9 is an exploded perspective view illustrating a slide rail (130) according to one embodiment of the present invention. Fig. 10 is a partially enlarged view illustrating a state in which the slide stopper (171) and the lower cover portion (180) are exploded in part A of Fig. 6.

[0141] Referring to FIGS. 6 to 10, a mount unit (100) according to one embodiment of the present invention is provided with a slide rail (130), which can provide a slide movement path of a slide unit (200) to be described later.

[0142] Referring to FIG. 19 and FIG. 23, the slide unit (200) can slide back and forth on the slide rail (130) provided in the mount unit (100), and the optical module (300) installed in the slide unit (200) can irradiate light onto the user's body.

[0143] In this specification, 'front' means the direction in which a user seated on the massage device faces, and 'rear' means the direction in which the back of a user seated on the massage device faces.

[0144] In this specification, a slide rail (130) is provided in a mount portion (100), and a moving unit (230) provided in a slide portion (200) to be described later can be placed on the slide rail (130).

[0145] However, it is not limited to this, and within the technical concept of the slide part (200) sliding on the mount part (100), various modifications are possible, such as a slide rail being provided on the slide part (200) and a moving unit being provided on the mount part (100).

[0146] Hereinafter, a detailed description will be given on the assumption that the slide rail (130) is provided on the mount portion (100) and the moving unit (230) is provided on the slide portion (200), so that the slide portion (200) slides on the mount portion (100).

[0147] Referring to FIG. 5, the mount part (100) can be detachably connected to the back cover part (400). The back cover part (400) is detachably connected to the back of the massage device, specifically the body massage part (1000), and can be positioned and fixed in a preset area on the back of the massage device, specifically the body massage part (100).

[0148] In the present invention, the mount part (100) is detachably connected to the back cover part (400) coupled to the body massage part (1000), but is not limited thereto. If the back cover part (400) is formed integrally with the body massage part (1000), the mount part (100) can be detachably directly connected to the body massage part (1000).

[0149] Referring to Fig. 19, in a state where the slide part (200) and the optical module (300) installed in the slide part (200) are located at the rear (scalp care mode) on the mount part (100), the light irradiator (10) can irradiate light to the user's scalp.

[0150] Referring to Fig. 23, in a state where the slide unit (200) and the optical module (300) placed on the slide unit (200) are positioned in front on the mount unit (100) (facial care mode), the light irradiator (10) can irradiate light onto the user's face.

[0151] The user can slide back and forth along a preset direction, specifically forward and backward, on the mount (100) by grasping one side of the slide (200).

[0152] However, it is not limited to this, and various modifications are possible, such as providing an actuator in the slide portion (200) or the mount portion (100) and driving the actuator to slide the slide portion (200) on the mount portion (100).

[0153] Referring to FIGS. 6 to 10, a mount unit (100) according to one embodiment of the present invention may include a mount upper housing (110), a mount lower housing (120), a slide rail (130), a mount bracket (140), a mount roller unit (150), a rail cover (160), a slide stopper (171), and a lower cover unit (180).

[0154] Referring to FIGS. 4 and 5, the mount upper housing (110) according to one embodiment of the present invention forms the exterior of the mount portion (100) together with the mount lower housing (120), and a slide rail (130) can be placed in the internal space formed by the mount upper housing (110) and the mount lower housing (120).

[0155] The upper mount housing (110) is positioned on the outside of the slide rail (130), and a slide slit (111) that exposes the slide rail (130) to the outside of the mount portion (100) can be formed.

[0156] Referring to FIG. 7 and FIG. 8, the slide slit (111) formed in the mount upper housing (110) can be formed by cutting a predetermined section along the length direction of the mount upper housing (110).

[0157] In this specification, the ‘longitudinal direction’ of the mount upper housing (110) means the direction in which the slide part (200) slides on the mount part (100).

[0158] Referring to FIG. 7, the moving unit (230) provided in the slide unit (200) to be described later can be placed on the slide rail (130) by penetrating the slide slit (111) formed in the upper mount housing (110).

[0159] The slide slit (111) can provide a path along which the moving unit (230) and the slide unit (200) including the moving unit (230) slide together with the slide rail (130) slide. That is, the slide unit (200) can slide forward and backward along the slide slit (111).

[0160] Referring to FIGS. 7 and 8, a wire receiving cover (112) may be provided on the inside of the slide slit (111). A cover penetration hole (112h) may be formed in the wire receiving cover (112) through which a wire (340) (or a flexible printed circuit board) is introduced or withdrawn when the slide unit (200) slides along the slide rail (130).

[0161] The wire receiving cover (112) can provide a space for receiving a wire (340). In this specification, the 'wire (340)' is an optical module (300), specifically, a light emitting module (320) and a power source (not shown in the drawing), and an electrical connection between the light emitting module (320) and the control unit (1200), and may be a flexible printed circuit board.

[0162] When the slide part (200) slides along the slide rail (130) provided in the mount part (100) due to the wire receiving cover (112), there is an effect of preventing twisting of the wire (340).

[0163] That is, the wire receiving cover (112) can prevent twisting of the wire (340) by providing a space in which the wire (340) can be introduced or withdrawn when the slide part (200) moves relative to the mount part (100).

[0164] Specifically, the wire (340) can pass through a cover penetration hole (112h) formed in the wire receiving cover (112) and move from the upper side of the wire receiving cover (112) (based on FIG. 26) to the lower side of the wire receiving cover (112) (based on FIG. 26).

[0165] From another perspective, when the slide unit (200) moves from the front to the rear, the wire (340) passes through the cover penetration hole (112h) formed in the wire receiving cover (112) and is introduced into the inside of the wire receiving cover (112), and when the slide unit (200) moves from the rear to the front, the wire (340) passes through the cover penetration hole (112h) formed in the wire receiving cover (112) and can be pulled out to the outside of the wire receiving cover (112).

[0166] Due to this, even if the slide part (200) moves forward and backward on the mount part (100), specifically the slide rail (130), the wires (340) can be placed on the upper and lower sides with respect to the wire receiving cover (112), so that there is an effect of preventing the wires (340) from being twisted when the slide moves.

[0167] Referring to FIGS. 7 and 8, a first receiving groove (113) that is drawn inward may be formed in the shape of a groove at the front end of the upper mount housing (110). The first receiving groove (113) is formed at a position corresponding to a second receiving groove (121) formed in the lower mount housing (120), and may be connected to each other.

[0168] An optical module (300) installed in the slide unit (200) can be placed in the space formed by the first receiving groove (113) and the second receiving groove (121) being interlocked and combined.

[0169] That is, when the slide part (200) slides to the rearmost position with respect to the mount part (100), the optical module (300) installed in the slide part (200) can be accommodated in the space formed by the first accommodation groove part (113) and the second accommodation groove part (121).

[0170] From another perspective, the optical module (300) can be accommodated inside the first accommodation groove (113) and the second accommodation groove (121).

[0171] Referring to FIGS. 6, 8, and 9, a mount lower housing (120) according to one embodiment of the present invention is coupled with a mount upper housing (110) so that a slide rail (130) is positioned inside, and can be placed on the lower side (based on FIG. 8) of the mount upper housing (110).

[0172] One side (upper side as shown in FIG. 8) of the mount lower housing (120) is coupled to the mount upper housing (110), and the other side opposite thereto can be fixed in position and coupled to the mount bracket (140).

[0173] A hole (drawing symbol not set) may be formed in the mount lower housing (120) to allow a wire (340) (or a flexible printed circuit board) to pass through, and thus the wire (340) accommodated between the mount upper housing (110) and the mount lower housing (120) may be discharged to the outside of the mount portion (100).

[0174] Referring to Fig. 10, a lower cover part (180), which will be described later, can be coupled to one side (the lower surface based on Fig. 10) of the mount lower housing (120). Specifically, a slide stopper (171), which will be described later, can be placed on the front end of a slide rail (130) disposed in the mount lower housing (120). The lower cover part (180) will be described in detail later.

[0175] Referring to FIGS. 7 and 8, a second receiving groove (121) that is drawn inward may be formed in the shape of a groove at the front end of the mount lower housing (120). The second receiving groove (121) is formed at a position corresponding to the first receiving groove (113) formed in the mount upper housing (110), and may be connected to each other.

[0176] An optical module (300) installed in the slide unit (200) can be placed in the space formed by the first receiving groove (113) and the second receiving groove (121) being interlocked and combined.

[0177] That is, when the slide part (200) slides to the rearmost position with respect to the mount part (100), the optical module (300) installed in the slide part (200) can be accommodated in the space formed by the first accommodation groove part (113) and the second accommodation groove part (121).

[0178] Referring to FIGS. 8 and 9, a slide rail (130) according to one embodiment of the present invention provides a movement path of a slide portion (200) and can be placed between a mount upper housing (110) and a mount lower housing (120).

[0179] In other words, the slide rail (130) can provide a slide movement path of the slide part (200) with respect to the mount part (100).

[0180] Specifically, the slide rail (130) can be coupled to the bottom surface of the mount upper housing (110). Although not shown in the drawing, the slide rail (130) can be coupled to the bottom surface of the mount upper housing (110) and fixed in position by a fastening member such as a bolt.

[0181] However, it is not limited to this, and various modifications are possible, such as a slide rail (130) being coupled to the upper surface of the mount lower housing (120) within the technical concept of providing a movement path of the slide part (200) while being placed in an internal space surrounded by the mount upper housing (110) and the mount lower housing (120).

[0182] The slide rail (130) may be formed of a metal material or an injection molded material. The interior of the slide rail (130) may be exposed to the outside through a slide slit (111) formed in the mount upper housing (110).

[0183] This allows the moving unit (230) to pass through the slide slit (111) and be connected to the slide rail (130).

[0184] Referring to FIG. 9, a slide rail (130) according to one embodiment of the present invention may include a rail base part (131) and a rail side part (133).

[0185] The rail base part (131) is formed to extend forward and backward, and is connected to the mount part (100), specifically the mount upper housing (110), and can be fixed in position.

[0186] On one side of the rail base part (131) facing the mount upper housing (110) (the upper side as shown in FIG. 9), a base through hole (131h) may be formed in the shape of a hole so that a wire (340) (or flexible printed circuit board) connected to the optical module (300), specifically the light-emitting module (320), can pass through.

[0187] Accordingly, the wire (340) passing through the base penetration hole (131h) can pass through the mount bracket (140) and the bracket connection part (455) provided in the back cover part (400) and be electrically connected to the massage device, specifically, the control part (1200) or the electric unit installed in the body massage part (1000).

[0188] The rail base part (131) can be formed into a convex curved shape toward one side (upper side as shown in FIG. 8).

[0189] Referring to FIG. 9, the rail base part (131) may include a first base surface in which a base penetration hole (131h) is formed, and a pair of second base surfaces that are connected to both sides of the first base surface based on the longitudinal direction and form a preset angle, specifically, perpendicular to the first base surface.

[0190] The second base surface can be in surface contact with the rail side part (133) to be described later, and since the rail side part (133) that is bent upward and formed in the shape of the letter 'ㄱ' and the rail base part (131) are combined, a rail having a cross-section in the shape of the letter 'ㄷ' along both sides based on the longitudinal direction of the slide rail (130) can be formed in the shape of a groove.

[0191] A moving side part (235) provided on the moving unit (230) can be placed on the inside of a rail having a preset depth, and the moving unit (230) has the effect of being able to slide back and forth in a preset direction, i.e., forward and backward, on the slide rail (130).

[0192] The rail base part (131) and the rail side part (133) can be connected by welding the areas where they are connected to each other. However, this is not limited to this, and various modifications are possible, such as joining by penetrating fastening of fastening members such as bolts.

[0193] A pair of rail side parts (133) are provided and are respectively connected to both sides of the rail base part (131), and can cover a preset area of ​​the rail base part (131) along the front and rear.

[0194] The rail side part (133) is coupled to the rail base part (131), specifically, the second base surface formed on both sides along the longitudinal direction, and a pair may be provided to correspond to a pair of the second surfaces.

[0195] The rail side part (133) is bent upward and formed in an ‘ㄱ’ shape, and may include a first side surface facing the first base surface and a second side surface connected to the second base surface while making surface contact.

[0196] The first side surface and the second side surface can be connected vertically at a preset angle, and by being combined with the rail base part (131), a 'ㄷ' shaped rail can be formed in the shape of a groove along the longitudinal direction of the slide rail (130).

[0197] Since the slide rail (130) having a 'ㄷ' shaped rail is not provided as an integral part, but includes a rail base part (131) and a pair of rail side parts (133), mass production and molding and processing properties can be improved compared to when the slide rail (130) is formed as an integral part.

[0198] A pair of rail side parts (133) can be formed into a convex curved shape toward one side (upper side as shown in FIG. 9) to correspond to the shape of the rail base part (131).

[0199] Accordingly, compared to the case where a slide rail having a 'ㄷ' shaped rail is formed integrally, where it is difficult to implement a curved shape, there is an effect of improving mass productivity by combining a rail base part (131) and a rail side part (133) each having a curved shape.

[0200] Referring to Fig. 9, a rail engaging groove (131a) and a rail engaging projection (133a) may be formed on the rail base part (131) and the rail side part (133) facing each other, respectively. The rail engaging groove (131a) and the rail engaging projection (133a) are formed at positions corresponding to each other, and a plurality of them may be provided.

[0201] A plurality of rail catch grooves (131a) and rail catch projections (133a) can be spaced apart along the length of the slide rail (130).

[0202] In the present invention, a rail catch (133a) may be formed to protrude on a rail side part (133), and a rail catch groove (131a) may be formed on a rail base part (131) facing the rail catch (133a) so that the rail catch (133a) may be hung on it.

[0203] However, it is not limited to this, and various modifications are possible, such as a rail catch protrusion being formed protrudingly on the rail base part (131) and a rail catch groove being formed on the rail side part (133).

[0204] Since a rail catch projection (133a) and a rail catch groove (131a) are formed at preset positions along the longitudinal direction (front-rear direction) of the slide rail (130), the joint position between the rail base part (131) and the rail side part (133) can be guided.

[0205] In addition, since the rail base part (131) and the rail side part (133) are precisely hooked and connected at preset positions, there is an effect of improving the accuracy and precision of the slide rail (130) assembly.

[0206] In addition, as the rail base part (131) and the rail side part (133) are combined at preset positions, the moving unit (230) has the effect of being able to move stably and secure continuity on the 'ㄷ' shaped rail.

[0207] Referring to Fig. 9, a positioning hole (130h) may be formed through the slide rail (130). The positioning hole (130h) may be formed at the front end and the rear end along the longitudinal direction of the slide rail (130), respectively.

[0208] Specifically, the positioning hole (130h) can be formed on the second base surface provided on the rail base part (131) and the second side surface provided on the rail side part (133) that is in surface contact with the second base surface. The positioning hole (130h) formed on the second base surface and the positioning hole (130h) formed on the rail side part (133) can be arranged to overlap each other.

[0209] A positioning member (239) provided in the moving unit (230) can be mounted in the positioning hole (130h) formed at the front and rear ends of the slide rail (130). This makes it possible to determine the position of the moving unit (230) moving on the slide rail (130).

[0210] The position determining member (239) may have an outer circumferential surface formed into a curved shape. Accordingly, as the moving unit (230) moves on the slide rail (130), the position of the moving unit (230) can be determined when the preset area of ​​the position determining member (239) is inserted and settled into the position determining hole (130h).

[0211] Thereafter, when a predetermined external force is applied to the moving unit (230), the positioning member (239) can be separated from the positioning hole (130h), and the moving unit (230) can be in a state where it can slide on the slide rail (130).

[0212] Referring to FIG. 8, a rail cover (160) may be placed between the slide rail (130) and the mount upper housing (110).

[0213] Specifically, the rail cover (160) is placed between the rail side part (133) and the mount upper housing (110), and can be formed of a material capable of elastic deformation.

[0214] As an optional embodiment, the rail cover (160) may include an adhesive material and may be placed on one side (upper side as shown in FIG. 8) of the slide rail (130), specifically the rail side part (133).

[0215] As an optional embodiment, the rail cover (160) may be coupled to the mount upper housing (110) on one side (the upper side as shown in FIG. 8) by a tape having a separate adhesive material, and the opposite side (the lower side as shown in FIG. 8) may be coupled to the slide rail (130), specifically, the rail side part (133).

[0216] There is an effect that the slide rail (130) can be stably attached, coupled, and fixed in position at a preset position on the lower surface of the mount upper housing (110) due to the rail cover (160).

[0217] The rail cover (160) according to one embodiment of the present invention may be formed of a material capable of elastic deformation. This has the effect of absorbing vibrational shock generated as the slide unit (200) moves on the mount unit (100), and alleviating shock transmitted to the mount unit (100) through the slide unit (200).

[0218] Referring to FIGS. 6, 8, 20, 27 to 30, a mount bracket (140) according to one embodiment of the present invention is coupled to a mount lower housing (120) and can be connected to a back cover part (400) coupled to a body massage part (1000).

[0219] Specifically, the mount bracket (140) rotates relative to the back cover part (400) based on a preset rotation center axis and can be detachably coupled to the back cover part (400).

[0220] The mount bracket (140) is connected to the mount lower housing (120) and then inserted and fixed into the back cover portion (400), specifically the bracket connection portion (455) to be described later, thereby connecting the mount lower housing (120) and the back cover portion (400).

[0221] The inner side of the mount bracket (140) may be hollow and may be perforated along the longitudinal direction (upper and lower direction based on FIG. 8). The space formed on the inner side of the mount bracket (140) may provide a space in which a wire (340) (or electric wire), a flexible printed circuit board, or other electronic components may be placed.

[0222] A hole (drawing symbol not set) may be formed in the lower mount housing (120), and the hole may be connected to a space formed on the inside of the mount bracket (140). As a result, a wire (340) (or wire, flexible printed circuit board) connected to the light-emitting module (320), specifically, the printed circuit board (321), may pass through the lower mount housing (120), the mount bracket (140), and the back cover (400) and be electrically connected to the control unit (1200) provided in the massage device (1).

[0223] The mount bracket (140) can be detachably connected to the mount lower housing (120). Specifically, since a fastening member such as a bolt penetrates the mount bracket (140) and is fastened to the mount lower housing (120), the mount bracket (140) can be positionally fixed to the mount lower housing (120).

[0224] As an optional embodiment, the height of the mount bracket (140) may be adjusted according to the user's physical condition. For example, the insertion area of ​​the mount bracket (140) inserted into the bracket connection portion (455) provided in the back cover portion (400) may have multiple stages and various heights.

[0225] Accordingly, a user who wishes to use the massage device can select a mount bracket (140) of a height corresponding to the user's height and attach it to the mount lower housing (120).

[0226] If the user is tall, the light source (10) may touch or collide with the user's head when the user sits on the massage device (1). In this case, a relatively tall mount bracket (140) that matches the user's height may be attached to the mount lower housing (120).

[0227] Conversely, if the user's sitting height is low, a problem may arise where the light irradiated from the light emitter (10) when the user sits on the massage device (1) is not transmitted to the body with sufficient intensity. In this case, a relatively low mount bracket (140) that is adjusted to the user's height may be attached to the mount lower housing (120).

[0228] That is, mount brackets (140) of various heights can be manufactured and provided at various heights according to the user's body, and the user can use the light irradiator (10) by selecting and installing a mount bracket (140) of an appropriate height according to his / her height.

[0229] Referring to FIGS. 27 to 30, the mount bracket (140) can be detachably inserted and connected to the bracket connection portion (455) provided in the back cover portion (400).

[0230] A first catch (141) may be formed protrudingly on the outer surface of the mount bracket (140) facing the bracket connection portion (455), and a first catch groove (457) may be formed in the back cover portion (400), specifically, the bracket connection portion (455), into which the first catch (141) may be inserted.

[0231] The first catch (141) can be selectively fastened to the first catch groove (457) depending on the relative rotation angle of the bracket connecting portion (455) and the mount bracket (140).

[0232] Specifically, the first catch (141) provided on the mount bracket (140) and the first catch groove (457) provided on the bracket connection portion (455) can be engaged in the up-and-down direction (based on FIG. 5) depending on the relative rotation angle of the mount bracket (140) and the bracket connection portion (455).

[0233] Looking at this from another perspective, a catch space is formed on the inside of the first catch (141), and a first catch groove (457) is positioned in the catch space, and the first catch (141) can be caught and fastened.

[0234] Referring to FIG. 27 and FIG. 28, the first catch (141) can be positioned on the inside of the first catch groove (457), and when the mount bracket (140) is rotated clockwise (based on FIG. 27) with respect to the bracket connecting portion (455) that is fixed in position, the first catch (141) can be engaged with and hung on the first catch groove (457).

[0235] As a result, the mount bracket (140) and the bracket connection part (455) are connected, and the mount part (100) can be prevented from being separated in the height direction (up-down direction based on FIG. 5) with respect to the back cover part (400).

[0236] A plurality of first hooks (141) may be provided, and a plurality of first hook grooves (457) may also be provided to correspond to a plurality of first hooks (141). The plurality of first hooks (141) may be spaced apart from each other along the circumferential direction based on the longitudinal central axis of the mount bracket (140).

[0237] A plurality of first catch grooves (457) can be spaced apart along the circumferential direction based on the longitudinal central axis of the bracket connecting portion (455).

[0238] Referring to FIGS. 27 to 30, the mount bracket (140) is inserted into the bracket connection portion (455) so that the first catch (141) of the mount bracket (140) and the first catch groove (457) of the bracket connection portion (455) do not hang or overlap in the vertical direction (height direction), and the mount bracket (140) and the mount lower housing (120) to which the mount bracket (140) is coupled are rotated so that the first catch (141) hangs over the first catch groove (457) and overlaps in the vertical direction, thereby fastening and positioning the mount portion (100), specifically the mount bracket (140), to the back cover portion (400), specifically the bracket connection portion (455).

[0239] Referring to FIG. 27 and FIG. 29, the mount bracket (140) is inserted into the bracket connecting portion (455) so that the first catch (141) and the first catch groove (457) do not overlap in the vertical direction.

[0240] Referring to FIG. 28 and FIG. 30, when the mount portion (100) is rotated clockwise (based on FIG. 29) relative to the rotation center axis (cp) with respect to the back cover portion (400), the first catch protrusion (141) formed on the mount bracket (140) and the first catch groove (457) formed on the bracket connection portion (455) overlap and are fastened in the vertical direction.

[0241] As the first catch (141) and the first catch groove (457) overlap along the height direction, there is an effect of preventing the mount portion (100) provided with the mount bracket (140) from being separated from the back cover portion (400) provided with the bracket connection portion (455).

[0242] The mount bracket (140) can be separated from the bracket connection part (455) through the reverse process of the above-described process. That is, as the mount part (100) is rotated counterclockwise (based on FIG. 30) relative to the back cover part (400) in the state illustrated in FIGS. 28 and 30, the first catch protrusion (141) formed on the mount bracket (140) and the first catch groove (457) formed on the bracket connection part (455) are released from overlapping along the height direction, and the mount part (100) can be separated from the back cover part (400).

[0243] Referring to FIG. 6, FIG. 27, and FIG. 28, a second engaging groove (142) may be formed on one side of the mount bracket (140) facing the bracket connecting portion (455). A second engaging projection (456) formed on the bracket connecting portion (455) may be inserted into the second engaging groove (142).

[0244] The second catch (465) can be selectively fastened to the second catch groove (142) depending on the relative rotation angle of the bracket connecting portion (455) and the mount bracket (140).

[0245] The mount portion (100) can be fastened to the back cover portion (400) by simultaneously engaging the first hooking projection (141) formed on the mount bracket (140) with the first hooking groove (457) formed on the bracket connecting portion (455) and engaging the second hooking projection (456) formed on the bracket connecting portion (455) with the second hooking groove (142) formed on the mount bracket (140).

[0246] The present invention discloses a structure in which a mount bracket (140) provided in a mount portion (100) and a bracket connection portion (455) provided in a back cover portion (400) are detachably coupled by overlapping along the height direction as they rotate relative to each other, but is not limited thereto, and various modifications such as a screw fastening method, a hook fastening method, and a fastening member use method are possible within the technical concept of detachably coupling the mount portion (100) to the back cover portion (400).

[0247] Referring to FIGS. 7, 8, 25, and 26, a mount roller unit (150) according to one embodiment of the present invention is rotatably connected to a mount upper housing (110) and is capable of making cloud contact with a slide unit (200).

[0248] Referring to FIG. 7 and FIG. 8, the mount roller portion (150) may include a mount roller (151) and a mount roller holder (153).

[0249] Referring to Fig. 22, the mount roller (151) is capable of cloud contact with the slide portion (200) and can rotate around a preset rotational center axis. The mount roller holder (153) supports the rotation of the mount roller (151) and can be installed in the mount upper housing (110).

[0250] Referring to FIG. 8, the mount roller (151) may be rotatably placed directly on the mount upper housing (110), or may be rotatably placed on the mount roller holder (153) while being spaced apart from the mount upper housing (110).

[0251] That is, when a mount roller holder (153) in which a mount roller (151) is rotatably arranged is installed in the mount upper housing (110), the mount roller (151) can be arranged at a distance from the mount upper housing (110), and there is an effect of reducing friction that may occur when there is direct contact between the mount upper housing (110) and the mount roller (151).

[0252] Referring to FIG. 8, the mount roller holder (153) is coupled to the inner surface of the mount upper housing (110), and the mount roller (151) rotatably positioned in the mount roller holder (153) can be exposed to the outside by passing through a hole formed in the mount upper housing (110).

[0253] However, it is not limited to this, and various modifications are possible, such as a groove having a preset depth is formed in the upper housing (110) of the mount, and a mount roller holder (153) in which a mount roller (151) is rotatably placed is inserted into the groove.

[0254] A plurality of mount rollers (151) may be provided, and may be arranged on both sides of the longitudinal central axis of the mount upper housing (110), and may be spaced apart from each other along the longitudinal direction of the mount upper housing (110).

[0255] Since the mount roller (151) is rotatably arranged on the mount upper housing (110), there is an effect of allowing the slide portion (200) to move smoothly relative to the mount portion (100). In addition, there is an effect of minimizing the contact area between the mount portion (100), specifically the mount upper housing (110), and the slide portion (200), specifically the slide lower housing (211), thereby preventing friction and resulting damage.

[0256] Referring to FIGS. 8 to 10, 24, and 26, a slide stopper (171) according to one embodiment of the present invention is connected to a slide rail (130) and can be placed at the front end of the slide rail (130). The slide stopper (171) can be fastened to the front end of the slide rail (130) by a fastening member (not shown in the drawing) such as a bolt and fixed in position.

[0257] Since the slide stopper (171) is arranged at the front end of the slide rail (130), the moving unit (230) moving on the slide rail (130) and the slide unit (200) including the same can be prevented from passing the front end of the slide rail (130) and being separated.

[0258] Referring to Fig. 24, the slide stopper (171) is contactable with the front end of the moving unit (230), specifically the moving side part (235).

[0259] Referring to Fig. 9, a buffer member (173) may be provided on one side of a slide stopper (171) facing a moving unit (230) moving on a slide rail (130). The buffer member (173) may be formed of a material capable of elastic deformation.

[0260] This has the effect of alleviating the impact when the moving unit (230), specifically the moving side part (235), moves to the front end of the slide rail (130) and collides with the buffer member (173).

[0261] Referring to Fig. 10, an attachment protrusion (172) may be formed protruding on one side (lower side based on Fig. 10) of the slide stopper (171) facing the lower cover part (180) to be described later.

[0262] The attachment protrusion (172) can be combined with the lower cover attachment portion (183) provided on the lower cover portion (180), and since the lower cover attachment portion (183) is attached and combined with the attachment protrusion (172), the lower cover portion (180) can be prevented from being separated from the mount lower housing (120).

[0263] In the present invention, the slide stopper (171) may be formed of a metal material, and the lower cover attachment portion (183) may be a magnet. As a result, the attachment protrusion (172) formed on the slide stopper (171) and the lower cover attachment portion (183) may be coupled by magnetic force.

[0264] Referring to FIG. 9 and FIG. 26, a position sensor (175) according to one embodiment of the present invention is disposed at least on one of the front end or the rear end of the slide rail (130) and can detect the position of the moving unit (230).

[0265] Referring to FIG. 9, in the present invention, the position sensor (175) is disposed at the rear end of the slide rail (130), but is not limited thereto, and various modifications are possible within the technical concept of being able to detect the position of the moving unit (230) moving on the slide rail (130), such as being disposed only at the front end or disposed at both the front end and the rear end.

[0266] In the following, the description will be given on the assumption that the position sensor (175) is placed at the rear end of the slide rail (130).

[0267] The position sensor (175) may be directly coupled to the rear end of the slide rail (130) or may be positioned at the rear end of the slide rail (130) while being coupled to the upper mount housing (110) and / or the lower mount housing (120).

[0268] For example, the position sensor (175) may be at least one of a micro switch, a reed switch, a proximity sensor, a light sensor, and a hall sensor.

[0269] If the position sensor (175) is a micro switch, it is possible to detect whether the moving unit (230) is placed at the rear end of the slide rail (130) by detecting whether the moving unit (230) has come into contact with the position sensor (175), and to transmit information about this to the control unit (1200) as an electrical signal through a wire (or electric wire, flexible printed circuit board).

[0270] If the position sensor (175) is a reed switch, the reed switch can be placed in the upper mount housing (110) corresponding to the rear end of the slide rail (130).

[0271] As an optional embodiment, the reed switch may be positioned and directly coupled to the rear end of the slide rail (130), or may be positioned in a mount lower housing (120) corresponding to the rear end of the slide rail (130).

[0272] The moving unit (230) may include a position sensor (175), specifically a magnet that can turn the reed switch on / off. For example, the magnet may be fixed to the moving unit (230) by a separate magnet bracket.

[0273] When the moving unit (230) slides along the slide rail (130) and the magnet provided in the moving unit (230) is positioned opposite the reed switch, the reed switch can be turned on.

[0274] Additionally, when the magnet moves away from the reed switch, the reed switch can be turned off. The control unit (1200) can obtain information about the location of the moving unit (230) through whether the reed switch is on / off.

[0275] Referring to FIGS. 6, 8, 10, 20, 24, and 26, the lower cover part (180) according to one embodiment of the present invention is coupled to the lower surface of the mount lower housing (120) and can cover an open area formed as much as a preset area in the mount lower housing (120).

[0276] The 'open area' is an area corresponding to the front end of the slide rail (130), and the lower cover part (180) can be placed at a position corresponding to an area where a slide stopper (171) fastened to the slide rail (130) is placed.

[0277] Referring to FIG. 10, the lower cover part (180) may include a lower cover body (181) and a lower cover attachment part (183).

[0278] The lower cover body (181) is detachably connected to the mount lower housing (120), and can prevent devices, electronic components, etc. placed inside the mount lower housing (120) from being exposed to the outside.

[0279] Referring to Fig. 10, the lower cover body (181) has a bending section and can be formed in an 'L' shape. A lower cover attachment part (183) can be attached to one side (upper side based on Fig. 10) of the lower cover body (181) facing the mount lower housing (120). The lower cover attachment part (183) can be attached to a slide stopper (171) arranged at the front end of the slide rail (130).

[0280] Specifically, the lower cover attachment portion (183) can be attached to an attachment protrusion (172) that protrudes outward from the slide stopper (171). The lower cover attachment portion (183) may be a magnet. As a result, it can be magnetically coupled to the attachment protrusion (172) formed of a metal material.

[0281] However, it is not limited to this, and various modifications are possible, such as the lower cover attachment part (183) being coupled to the mount lower housing (120) and being coupled through magnetic force with a fastening member such as a bolt formed of a metal material.

[0282] As an optional embodiment, the lower cover body (181) is formed of a metal material and can be coupled to a separate magnet and magnetic force placed on the mount lower housing (120) or slide rail (130).

[0283] On one side (rear side as shown in FIG. 10) of the lower cover body (181) where the lower cover attachment part (183) is placed, opposite the other side (front side as shown in FIG. 10), a lower hook (182) may be formed to protrude so as to be hooked and connected to a hook hooking groove (122) formed in the lower mount housing (120).

[0284] On one side, the lower cover attachment portion (183) is connected to the lower cover main body (181) and the attachment protrusion (172) formed on the slide stopper (171), and on the other side, the lower hook (182) is connected by being hooked to the hook hooking groove (122), thereby preventing the lower cover portion (180) from being separated from the mount lower housing (120).

[0285] FIG. 11 is a drawing illustrating a slide unit (200) and an optical module (300) according to one embodiment of the present invention. FIG. 12 is a drawing illustrating a slide lower housing (211) according to one embodiment of the present invention. FIG. 13 is a perspective view illustrating a moving unit (230) according to one embodiment of the present invention. FIG. 15 is a drawing illustrating a slide rail (130) and a moving unit (230) according to one embodiment of the present invention.

[0286] Referring to FIGS. 3 to 6, 11, 12, and 13, a slide unit (200) according to one embodiment of the present invention is capable of relative movement with a mount unit (100), and is capable of reciprocating sliding movement along a preset direction (front-back direction) on the mount unit (100), specifically, the slide rail (130).

[0287] An optical module (300) is coupled to one side of the slide unit (200) (the front side in FIG. 6), and as the slide unit (200) slides back and forth on the mount unit (100), the optical module (300) coupled to the slide unit (200) can move forward and backward.

[0288] Referring to FIG. 11, the slide unit (200) may include a slide housing unit (210) and a moving unit (230).

[0289] Referring to FIG. 11, the slide housing portion (210) accommodates an optical module (300) and may include a slide lower housing (211), a slide upper housing (213), a module frame (215), and a wire cover (217).

[0290] The slide upper housing (213) and the slide lower housing (211) form the exterior of the slide housing portion (210) and may be hollow on the inside. The slide lower housing (211) constitutes the lower portion of the slide housing portion (210) and may be formed of at least one of an injection molding material and a metal material.

[0291] A coupling hole (212) may be formed along the height direction on one side of the slide lower housing (211), specifically, on the front end. An optical module (300) may be inserted and coupled into the coupling hole (212). As the optical module (300) is inserted into the coupling hole (212) formed in the slide lower housing (211), the bottom surface of the optical module (300) may be exposed to the outside toward the user's scalp or face.

[0292] The coupling member (212) may be formed to protrude a predetermined length from the lower portion of the slide lower housing (211). As a result, the user can slide the slide unit (200) forward or backward with respect to the mount unit (100) after grasping a predetermined area of ​​the coupling member (212) formed to protrude to one side (the lower side as shown in FIG. 11).

[0293] The preset area of ​​the coupling member (212) may be formed of a material capable of preventing slipping, specifically, a rubber material. This allows the user to easily grip the coupling member (212) and move the slide member (200) into which the optical module (300) is inserted relative to the mount member (100).

[0294] Referring to Fig. 11, an installation hole (211a) may be formed on one side (the front end as of Fig. 11) of the slide lower housing (211) opposite to the other side (the rear end as of Fig. 11) where the coupling member (212) is formed.

[0295] Referring to FIG. 11, the moving unit (230) can be connected to the mount unit (100), specifically the slide rail (130), by penetrating the installation hole (211a) formed in the slide lower housing (211).

[0296] Specifically, the lower region (based on FIG. 11) of the moving unit (230) may be placed on the lower side (based on FIG. 11) of the slide lower housing (211) based on the installation hole (211a), and the upper region (based on FIG. 11) of the moving unit (230) may be placed on the upper side (based on FIG. 11) of the slide lower housing (211) based on the installation hole (211a).

[0297] The upper region of the moving unit (230) that passes through the installation hole (211a) can be fixed in position by being connected to the module frame (215) to be described later. The moving unit (230) can be connected to the module frame (215) through a fastening member such as a bolt.

[0298] However, it is not limited to this, and various modifications are possible, such as being fastened to the slide upper housing (213) within the technical concept of the moving unit (230) passing through the installation hole (211a) and being fixed in position, or being fastened to both the module frame (215) and the slide upper housing (213).

[0299] Meanwhile, the lower area of ​​the moving unit (230) that has passed through the installation hole (211a) can be exposed to the outside, and at least a part of the lower area of ​​the moving unit (230) that is exposed to the outside can be inserted and connected to the mount portion (100).

[0300] Referring to Fig. 11, a reinforcing rib (211b) may be formed to protrude along the longitudinal direction of the slide lower housing (211). A plurality of reinforcing ribs (211b) may be provided and may be arranged in parallel on both sides with respect to the central portion of the slide lower housing (211) along the longitudinal direction.

[0301] The rigidity of the slide lower housing (211) can be secured by forming the reinforcing rib (211b) to extend along the length.

[0302] The reinforcing rib (211b) may be formed integrally with the slide lower housing (211). However, it is not limited to this, and various modifications are possible, such as being formed separately and coupled to the slide lower housing (211).

[0303] Referring to FIGS. 11 and 12, a cover groove (211c) may be formed in the shape of a groove between a plurality of reinforcing ribs (211b) arranged in parallel in the slide lower housing (211). A wire (340) electrically connected to an optical module (300), specifically a light-emitting module (320), may be arranged in the cover groove (211c).

[0304] A wire cover (217) to be described later is installed on the upper side (based on FIG. 11) of the wire (340) placed on the cover groove (211c), and can cover the wire (340) (or flexible printed circuit board) placed on the cover groove (211c) between a plurality of reinforcing ribs (211b).

[0305] Referring to Fig. 11, a plurality of cover grooves (211c) may be provided and may be spaced apart along the length direction of the slide lower housing (211). A plurality of wire covers (217) may be provided to correspond to the plurality of cover grooves (211c).

[0306] A wire cover (217) can be placed between the slide lower housing (211) and the module frame (215).

[0307] Referring to Fig. 11, a support rib (211d) may be formed to protrude toward the outside (upper side based on Fig. 11) on the inside of the cover groove (211c). A plurality of support ribs (211d) may be provided and spaced apart from each other along the length direction.

[0308] The support rib (211d) has a preset thickness and can be formed to extend in a direction perpendicular to the length direction of the slide lower housing (211).

[0309] The support rib (211d) is capable of contacting the wire cover (217) that is seated in the cover groove (211c), and has the effect of supporting and supporting the wire cover (217) from one side (the lower side as shown in FIG. 11). A plurality of support ribs (211d) can be spaced apart in the width direction based on the longitudinal central axis of the slide lower housing (211) in a section that is preset along the longitudinal direction of the slide lower housing (211).

[0310] Referring to FIG. 11 and FIG. 12, a wire (340) can be arranged along the longitudinal direction of the slide lower housing (211) between a plurality of support ribs (211d) spaced apart in the width direction based on the longitudinal central axis of the slide lower housing (211).

[0311] Referring to FIGS. 11 and 12, the slide upper housing (213) according to one embodiment of the present invention constitutes the upper portion of the slide portion (200) and can cover the upper side of the optical module (300).

[0312] The slide upper housing (213) can be joined to the upper surface of the slide lower housing (211) and can be formed of at least one of an injection molded material or a metal material.

[0313] In the internal space formed by combining the slide upper housing (213) and the slide lower housing (211), a module frame (215), wires (340) (or wires, flexible printed circuit boards), and other electronic components, parts, etc. can be placed.

[0314] In addition, the optical module (300) is placed in front of the space formed between the slide upper housing (213) and the slide lower housing (211) and can be inserted into the coupling hole (212), and the wire (340) connected to the optical module (300), specifically the light emitting module (320), can pass through the internal area of ​​the moving unit (230) across the space and then pass through the installation hole (211a).

[0315] Referring to FIGS. 11 and 12, a module frame (215) according to one embodiment of the present invention is disposed between a slide upper housing (213) and a slide lower housing (211), and can be positionally fixed to the slide upper housing (213) or the slide lower housing (211).

[0316] Referring to Fig. 12, the module frame (215) covers the wire (340) provided in the optical module (300) and can be coupled to the slide lower housing (211). The following description will be made on the assumption that the module frame (215) is positionally fixed to the slide lower housing (211).

[0317] The module frame (215) can be connected to the slide lower housing (211) by a fastening member such as a bolt. On one side of the module frame (215) facing the slide lower housing (211) (the lower surface as shown in FIG. 11), a fixing rib (216) can be formed to protrude toward the slide lower housing (211).

[0318] A plurality of fixed ribs (216) are provided, and the plurality of fixed ribs (216) can be spaced apart along the width direction based on the longitudinal central axis of the module frame (215). In addition, the plurality of fixed ribs (216) can be spaced apart along the longitudinal direction of the module frame (215).

[0319] Due to this, the plurality of fixed ribs (216) can contact and pressurize both sides based on the center of the wire cover (217).

[0320] Referring to FIGS. 11 and 12, a fixed rib (216) formed to protrude on a module frame (215) can be positioned on the inside of a cover groove (211c) formed on a slide lower housing (211). Specifically, it can be positioned at a position corresponding to a support rib (211d) located on the inside of the cover groove (211c).

[0321] Referring to Fig. 12, a wire (340) connected to an optical module (300), specifically a light-emitting module (320), can be arranged along the length direction in the slide lower housing (211). That is, one end (front end) of the wire (340) is connected to a printed circuit board (321) provided in the light-emitting module (320), and the other end (rear end) opposite thereto can pass through an installation hole (211a).

[0322] The wire (340) can be arranged between a plurality of reinforcing ribs (211b) spaced apart in a longitudinal direction in the slide lower housing (211), and can be arranged on the inside of a cover groove (211c) spaced apart in a longitudinal direction.

[0323] Referring to FIGS. 11 and 12, a wire (340) formed to extend along the longitudinal direction is arranged on the inside of the cover groove (211c) in a preset section, and can be arranged between a plurality of support ribs (211d) spaced apart from each other along the width direction on the inside of the cover groove (211c).

[0324] Referring to FIGS. 11 and 12, a wire cover (217) may be placed on the cover home portion (211c). The wire cover (217) is placed on the slide lower housing (211) and may cover a preset section of the wire (340) located on the slide lower housing (211).

[0325] Referring to FIG. 12, the wire cover (217) can be placed on a support rib (211d) located on the inside of the cover groove (211c) while being placed on the outside of the wire (340).

[0326] As an optional embodiment, the wire cover (217) may include an adhesive material and may be placed on the support rib (211d) in an adhesive tape manner.

[0327] A plurality of wire covers (217) may be provided to correspond to a plurality of cover grooves (211c). A plurality of wire covers (217) may be spaced apart along the length direction of the slide lower housing (211).

[0328] Referring to FIG. 11 and FIG. 12, the module frame (215) can be coupled to the slide lower housing (211) while the wire (340) placed on the slide lower housing (211) is covered by the wire cover (217).

[0329] A fixed rib (216) protrudingly formed on one side (bottom surface as shown in FIG. 11) of the module frame (215) facing the slide lower housing (211) can be formed at a position facing the support rib (211d).

[0330] As a result, when the module frame (215) is fastened to the slide lower housing (211), the fixed rib (216) can contact and press the wire cover (217) placed on the support rib (211d), thereby preventing the wire (340) from being separated between the module frame (215) and the slide lower housing (211).

[0331] In addition, the fixed rib (216) contacts and presses a preset area of ​​the wire cover (217), specifically, a side area excluding the central area corresponding to the wire (340), thereby preventing the module frame (215) and the wire cover (217) from directly pressing the wire (340) excessively.

[0332] Referring to FIG. 12, one side (lower side based on FIG. 12) of the wire cover (217) is in contact with the support rib (211d), and the other side (upper side based on FIG. 12) of the wire cover (217) opposite thereto is in contact with the fixed rib (216) provided on the module frame (215), thereby preventing the wire (340) from being detached between the slide lower housing (211) and the module frame (215) while preventing the wire (340) from being damaged by not directly pressing the wire (340).

[0333] In the present invention, the module frame (215) is coupled to the slide lower housing (211), but is not limited thereto, and various modifications are possible, such as coupling to the slide upper housing (213) within the technical concept of a wire (340) being arranged between the module frame (215) and the slide lower housing (211).

[0334] Referring to FIGS. 7, 11, 13, and 15, a moving unit (230) according to one embodiment of the present invention is coupled to a slide housing portion (210), specifically, a module frame (215), and is movable on a slide rail (130).

[0335] Referring to FIG. 13, the moving unit (230) can be coupled to the bottom surface of the module frame (215) and can connect the slide housing portion (210) and the mount portion (100). The moving unit (230) can be penetrated and fastened to the slide housing portion (210).

[0336] Specifically, one side (upper side as shown in FIG. 13) of the moving unit (230) is connected to a module frame (215) provided in the slide housing part (210), and the other side (lower side as shown in FIG. 13) can be connected to the slide rail (130) by passing through an installation hole part (211a) formed in the slide lower housing (211).

[0337] The moving unit (230) can slide forward and backward along the slide rail (130). As the moving unit (230) slides, the entire slide unit (200) to which the optical module (300) is connected can slide on the mount unit (100).

[0338] Referring to FIG. 13, a moving unit (230) according to one embodiment of the present invention may include a moving base part (231), a moving side part (235), and a positioning member (239).

[0339] The movable base part (231) can be coupled to the slide housing part (210), specifically, to the bottom surface of the module frame (215). At least one fastening hole (232) can be formed in the movable base part (231). A separate fastening member, such as a bolt, can pass through the fastening hole (232) and be coupled to the module frame (215).

[0340] In the present invention, the moving base part (231) is connected to the module frame (215) by a fastening member, but is not limited thereto, and various modifications are possible, such as being connected to the slide upper housing (213).

[0341] The moving base part (231) can be connected to the module frame (215) by passing through the installation hole (211a) formed in the slide lower housing (211).

[0342] An insertion portion (233) may be formed protrudingly on both sides of the moving base part (231). The insertion portion (233) is inserted into an insertion groove portion (236) formed in the moving side part (235) to be described later, and the moving base hole (233h) may be formed in the shape of a hole portion.

[0343] The movable base part (231) and the movable side part (235) according to one embodiment of the present invention may be formed of different materials. Specifically, the movable base part (231) may be formed of a metal material, and the movable side part (235) may be formed of an injection molding material such as polyoxymethylene (POM), which has relatively good lubricity.

[0344] As a result, the inside of the moving base hole (233h) formed in the moving base part (231) during the injection molding process of the moving side part (235) is filled with the moving side part (235), and the fastening force between the moving base part (231) and the moving side part (235) can be improved.

[0345] The movable base part (231) may be open at the front and rear, and may be hollow inside. As a result, a wire (340) (or wire, flexible printed circuit board) electrically connected to the optical module (300), specifically the light-emitting module (320), can pass through the inside of the movable unit (230), specifically the movable base part (231), and pass through the base penetration hole (131h) formed in the slide rail (130), specifically the rail base part (131), and enter the internal space of the mount bracket (140).

[0346] Referring to Fig. 13, a pair of moving side parts (235) are provided and are coupled to both sides in the width direction of the moving base part (231), and are capable of contacting the slide rail (130).

[0347] The moving side part (235) has a preset depth and an insertion groove (236) is formed, and an insertion groove (233) provided in the moving base part (231) can be inserted into the insertion groove (236).

[0348] Referring to Fig. 13, a groove (not specified in the drawing) may be formed in at least one of the front and rear ends of the moving side part (235) so that a positioning member (239) can be inserted therein. The positioning member (239) may be formed to be longer than the depth of the groove formed in the moving side part (235).

[0349] This allows a preset area of ​​the positioning member (239) coupled to the moving side part (235) to be exposed to the outside and come into contact with the slide rail (130), specifically the rail base part (131) and the rail side part (133) that are connected and formed.

[0350] The outer surface of the positioning member (239) that comes into contact with the above rail can be formed into a curved shape, and has the effect of preventing movement in the width direction of the moving unit (230) while minimizing friction with the slide rail (130) and damage caused thereby.

[0351] Referring to Fig. 15, the positioning member (239) can be mounted in the positioning hole (130h) formed at the front and rear ends of the slide rail (130). This makes it possible to determine the position of the moving unit (230) moving on the slide rail (130).

[0352] Since the outer surface of the positioning member (239) exposed to the outside is formed in a curved shape, as the moving unit (230) moves on the slide rail (130), the preset area of ​​the positioning member (239) can be inserted and settled into the positioning hole (130h), and the position of the moving unit (230) can be determined.

[0353] Thereafter, when a predetermined external force is applied to the moving unit (230), the positioning member (239) can be separated from the positioning hole (130h), and the moving unit (230) can be in a state where it can slide.

[0354] Referring to FIGS. 13 and 24, the front end of the movable side part (235) can be positioned relatively forward compared to the front end of the movable base part (231). This allows the front end of the movable side part (235) to come into contact with the slide stopper (171) provided on the slide rail (130), and has the effect of preventing the movable base part (231) from directly contacting the slide stopper (171) and the resulting impact.

[0355] Referring to FIG. 9 and FIG. 15, as the moving unit (230) moves on the slide rail (130), the front end of the moving side part (235) can contact the slide stopper (171) coupled to the front end of the slide rail (130), specifically, the buffer member (173), and the rear end of the moving side part (235) can contact the position sensor (175) arranged at the rear end of the slide rail (130).

[0356] This can prevent the moving unit (230) from being separated from the slide rail (130).

[0357] Fig. 14 is a perspective view illustrating a mobile unit according to another embodiment of the present invention. Referring to Fig. 14, a reinforcing groove (231`a) may be formed in the shape of a groove in a preset area on a mobile unit (230`) according to another embodiment of the present invention, specifically, a mobile base part (231`).

[0358] The reinforcing groove (231`a) may be formed in a concave shape toward the outside and may be formed in the center of the movable base part (231`) along the longitudinal direction. A plurality of reinforcing grooves (231`a) may be provided and may be formed in parallel along the width direction of the movable base part (231`).

[0359] As the reinforcing groove (231`a) is folded and formed, the rigidity of the moving base part (231`) can be secured.

[0360] Referring to Fig. 14, a moving base hole (233`h) formed in an insertion portion (233`) provided in a moving base part (231`) can have a preset area cut out.

[0361] Accordingly, when the movable side part (235`) is formed by injection molding on the movable base part (231`), the injection molding material can easily penetrate, be inserted into, and be filled in the movable base hole (233`h) formed on the movable base part (231`), and the fastening force between the movable base part (231`) and the movable side part (235`) can be improved.

[0362] A moving unit (230`) according to another embodiment of the present invention has the same remaining configuration as the moving unit (230) according to one embodiment of the present invention, except that a reinforcing groove (231`a) is formed in the moving base part (231`) and a preset area of ​​a moving base hole (233`h) formed in an insertion part (233`) inserted into an insertion groove part (236`) formed in a moving side part (235`) is cut out, and therefore, a detailed description thereof will be omitted to the extent that it overlaps therewith.

[0363] Fig. 16 is an exploded perspective view illustrating an optical module according to one embodiment of the present invention. Fig. 17 is a cross-sectional side view of an optical module according to one embodiment of the present invention taken along line II` of Fig. 11.

[0364] Referring to FIGS. 4, 5, 11, 16, and 17, an optical module (300) according to one embodiment of the present invention is installed in a slide unit (200) and irradiates light onto a user's body, and can move together with the movement of the slide unit (200) when the slide unit (200) moves relative to the mount unit (100).

[0365] The optical module (300) can irradiate light onto the user's scalp or face. The optical module (300) can irradiate light of a specific wavelength onto the scalp or face to induce metabolism promotion in the relevant area and irradiate the user with a low-power laser that activates tissue function.

[0366] Referring to FIGS. 16 and 17, the optical module (300) may include a diffuser plate (310), a light-emitting module (320), a light-emitting module cover (330), and a wire (340). The diffuser plate (310) is coupled to the slide portion (200), specifically, the slide lower housing (211), and the bottom surface may penetrate the slide portion (200) and be exposed to the outside.

[0367] In the present invention, the diffuser plate (310) is fixed and connected to the slide lower housing (211) by a fastening member such as a bolt, but is not limited thereto, and various modifications are possible within the technical concept of the diffuser plate (310) being fixed and positioned on the slide lower housing (211).

[0368] The bottom surface of the diffuser plate (310) can be exposed to the outside by penetrating the slide lower housing (211) as it is placed in the coupling hole (212) formed in the slide lower housing (211).

[0369] The diffuser (310) can evenly distribute light generated from a light-emitting element and eliminate hot spots formed due to light being concentrated in a specific area. The bottom surface of the diffuser (310) can be formed with an inclined surface (311) that is inclined upward from the edge of the diffuser (310) toward the inner center of the diffuser (310).

[0370] Accordingly, when a user looks at the optical module (300), specifically the diffuser plate (310), the diffuser plate (310) can be formed into a shape with a concave center.

[0371] Referring to FIGS. 16 and 17, the light emitting module (320) is disposed on the inside of the diffuser plate (310), and may be disposed between the diffuser plate (310) and the light emitting module cover (330) to be described later. The light emitting module (320) may include at least one light emitting element (drawing symbol not set) and a printed circuit board (321) on which the light emitting element is disposed.

[0372] As an optional embodiment, the light-emitting element may be a light-emitting diode (LED). When the light-emitting element is a light-emitting diode, the light-emitting diode may be provided in combination with a red light-emitting diode that emits red light and a blue light-emitting diode that emits blue light.

[0373] Specifically, the light-emitting element may be a near-infrared (NIR) light-emitting diode or a human-centric lightning (HCL) light-emitting diode.

[0374] The printed circuit board (321) can be electrically connected to the control unit (1200) via a wire (340).

[0375] Referring to FIG. 12, FIG. 20, FIG. 24, and FIG. 26, a wire (340) (or a wire, a flexible printed circuit board) may be arranged to have one end connected to a printed circuit board (321) and to penetrate an internal space formed by being surrounded by a slide lower housing (211) and a slide upper housing (213), a moving unit (230), and a mount portion (100).

[0376] The wire (340) can electrically connect the printed circuit board (321) and the control unit (1200), and can be formed to extend into the inside of the mount unit (100) by penetrating the slide unit (200).

[0377] Specifically, the wire (340) is connected to a printed circuit board (321) provided in the optical module (300), and the other end can pass through the interior of the slide unit (200), specifically between the slide lower housing (211) and the module frame (215), and pass through the installation hole (211a) formed in the moving unit (230) and the slide lower housing (211).

[0378] Next, the wire (340) can pass through the cover penetration hole (112h) formed in the mount part (100), specifically the mount upper housing (110), and enter the internal space of the mount part (100), and pass through the base penetration hole (131h) formed in the slide rail (130), specifically the rail base part (131).

[0379] Next, the wire (340) is exposed to the outside of the mount lower housing (120) and passes through the inner space of the mount bracket (140) coupled to the mount lower housing (120) to be electrically connected to a printed circuit board or control unit (1200) provided in the back cover portion (400).

[0380] The inner surface of the installation hole (211a), the cover penetration hole (112h), and the base penetration hole (131h) through which the wire (340) passes may have a convexly curved shape facing inward. This prevents damage to the wire (340) due to friction when the wire (340) comes into contact with another component when the slide part (200) moves relative to the mount part (100).

[0381] The light emitting module (320) can irradiate light of various wavelengths in response to the position of the slide unit (200) moving relative to the mount unit (100). For example, the light emitting module (320) can irradiate light of various wavelengths in response to the position of the slide unit (200).

[0382] For example, when the slide part (200) is located at the rear of the mount part (100) and irradiates light onto the user's scalp (scalp care mode), the light emitting module (320) can irradiate light of a wavelength band that is effective for scalp care or hair loss prevention onto the user's scalp.

[0383] In addition, when the slide unit (200) slides forward and is positioned in front of the mount unit (100) (facial care mode), the light emitting module (320) can irradiate light of a wavelength band effective for whitening or wrinkle improvement onto the user's face.

[0384] For example, the light emitting module (320) can selectively irradiate light of a wavelength band of 420 to 480 nm, 630 to 690 nm, or 850 to 940 nm to the user's scalp or face.

[0385] Referring to FIGS. 16 and 17, a light emitting module cover (330) is coupled to the upper portion of a diffuser plate (310) and can cover a light emitting module (320) placed on the diffuser plate (310). The light emitting module cover (330) can prevent the light emitting module (320) from being contaminated with foreign substances or damaged by external impact.

[0386] At least one heat dissipation slit (331) may be formed through the light emitting module cover (330). Heat generated in the light emitting module (320) may be dissipated to the outside of the optical module (300) through the heat dissipation slit (331).

[0387] Referring to FIG. 17, the light emitting module (320) can be spaced apart from the diffuser plate (310) and can be connected to the light emitting module cover (330) by a fastening unit (350) such as a bolt.

[0388] Fig. 18 is an exploded perspective view illustrating a back cover portion (400) according to one embodiment of the present invention.

[0389] Referring to FIGS. 3 to 5, 18, 19, 29, and 31, the back cover part (400) is detachably connected to one side of the body massage part (1000) that provides a massage function to a part of the user's body, and may include an inner cover (410), an outer cover (430), and a bracket fixing part (450).

[0390] Referring to Fig. 18, the inner cover (410) is connected to one side of the massage unit, specifically the body massage unit (1000), and can be fixed in position by being combined with the body massage unit (1000) by a fastening member such as a bolt.

[0391] However, it is not limited to this, and various modifications are possible, such as a groove being formed in the body massage part (1000) and the inner cover (410) being fastened to the groove in a hooking manner.

[0392] Referring to Fig. 18, the outer cover (430) forms the exterior of the back cover portion (400), and can be combined with one side (the lower side as shown in Fig. 18) of the inner cover (410) that is coupled with the body massage portion (1000) and the other side (the upper side as shown in Fig. 18).

[0393] The outer cover (430) can be connected to the inner cover (410) in multiple areas by fastening members such as bolts. However, this is not limited to this, and various modifications are possible, such as a groove being formed in the inner cover (410) and the outer cover (430) being connected to the groove in a hooking manner.

[0394] Referring to Fig. 18, a bracket fixing part (450), specifically a bracket fixing base (451), to be described later, may be placed between the inner cover (410) and the outer cover (430).

[0395] A bracket fixing base can be placed in the internal space formed between the inner cover (410) and the outer cover (430), and a bracket connecting portion (455) can be placed on the outer circumferential surface of the outer cover (430).

[0396] Fastening members such as bolts are fastened by penetrating the bracket connecting portion (455), outer cover (430), and bracket fixing base (451), so that the position of the bracket fixing portion (450) can be stably fixed on the outer cover (430).

[0397] The outer cover (430) has a depth preset so that a bracket fixing portion (450), specifically a bracket connecting portion (455), can be inserted, and a bracket insertion groove (431) can be formed in the shape of the groove portion.

[0398] That is, a bracket insertion groove (431) having a preset depth and capable of accommodating the bracket connection portion (455) can be formed on one side of the outer cover (430) facing the bracket fixing portion (450), specifically the bracket connection portion (455).

[0399] A plurality of fastening holes (drawing symbol not set) can be formed on the bottom surface of the bracket insertion groove (431), and a fastening member can pass through the fastening holes to fasten the bracket connecting portion (455) and the outer cover (430).

[0400] In addition, a bracket fixing base (451) can be placed so as to be in contact with one side (upper side as shown in FIG. 18) of the bracket insertion groove (431) facing the bracket connecting portion (455) and the other side (lower side as shown in FIG. 18).

[0401] A fastening member such as a bolt can pass through the fastening hole to fasten the bracket fixing base (451) and the outer cover (430).

[0402] Referring to FIGS. 18, 19, 27 to 30, a bracket fixing part (450) according to one embodiment of the present invention is coupled to an inner cover (410) and an outer cover (430), and a mount part (100) on which an optical module (300) that irradiates light onto a user's body is arranged to be slidable can be detachably connected.

[0403] Referring to FIG. 18, the bracket fixing part (450) may include a bracket fixing base (451) and a bracket connecting part (455).

[0404] The bracket fixing base (451) is coupled to the inner cover (410) and the outer cover (430), and can be placed between the inner cover (410) and the outer cover (430). The bracket fixing base (451) can include a fixing base body (451a) and a fixing base extension (451b).

[0405] Referring to Fig. 18, the fixed base body (451a) can be in surface contact with the outer cover (430) and can be coupled to the outer cover (430) by a fastening member. The fixed base body (451a) can have a passage hole (450h) formed in the shape of a hole so that a wire (340) can pass through it.

[0406] The wire (340) passing through the passage hole (450h) can be electrically connected to the control unit (1200), the electric unit, etc.

[0407] The fixed base extension (451b) is connected to the fixed base body (451a) and can be formed to extend at a preset angle, specifically perpendicular to the fixed base body (451a). The fixed base extension (451b) is connected to the inner cover (410) and can be specifically inserted through the inner cover (410).

[0408] The fixed base extension (451b) can be connected to the inner cover (410) by a fastening member (drawing symbol not specified) such as a bolt. A plurality of fixed base extensions (451b) are provided, and the plurality of fixed base extensions (451b) are arranged in parallel and can each be inserted through the inner cover (410).

[0409] The fixed base body (451a) and the fixed base extension (451b) may be formed integrally. However, this is not limited to the above, and various modifications, such as being provided as separate parts and fastened or welded together, are possible.

[0410] The fixed base body (451a) can be coupled to one surface (bottom surface as shown in FIG. 18) of the outer cover (430), specifically, the bracket insertion groove (431) formed in the outer cover (430) so that the bracket connection portion (455) can be inserted.
