smart glass devices

[0001] The present invention relates to a smart glass device.

[0002] Augmented Reality (AR) technology refers to a technology that superimposes virtual objects onto the real world that the user sees.

[0003] Unlike virtual reality (VR) technologies that consist solely of a virtual environment, this AR technology provides images that blend the real world with virtual objects. Users can view the real world while receiving enhanced realism and additional information.

[0004] Smart glasses worn on the user's face are stored and charged in a charging case.

[0005] Smart glasses need to be stored safely in the charging case and charged without interruption.

[0006] An object of the present invention is to provide a smart glass device in which the smart glass is stably stored in a charging case and charged without interruption.

[0007] The above-described object of the present invention is achieved by the specific contents described below.

[0008] A smart glass device according to an embodiment of the present invention includes smart glasses and a charging case. The smart glasses are worn on a user's face.

[0039] Below, a smart glass apparatus according to an example of an embodiment of the present invention is described.

[0040] Figures 1 and 2 illustrate a smart glass device according to an example of an embodiment of the present invention.

[0041] Referring to FIGS. 1 and 2, a smart glass device according to an exemplary embodiment of the present invention includes a smart glass (1) and a charging case (2). FIG. 1 shows the charging case (2) in a closed state, and FIG. 2 shows the charging case (2) in an open state. The smart glass (1) is accommodated in the charging case (2).

[0042] Smart glasses (1) are augmented reality (AR) devices worn on the user's face. Through the smart glasses (1), the user can view images that blend real-world environments with virtual objects. This specification omits a general description of smart glasses (1), and instead provides a detailed description of the present invention.

[0043] The charging case (2) is a case for storing smart glasses (1) and is a case that supplies electricity to the battery built into the smart glasses (1) to charge the battery.

[0044] Below, the smart glasses (1) and charging case (2) are described in order.

[0045] Smart Glasses (1)

[0046] Figures 3 to 5 illustrate smart glasses (1) of the present invention.

[0047] The smart glass (1) includes two lenses (12), a lens cover (11) that accommodates the two lenses (12), and two temples (13) that are connected to the lens covers (11).

[0048] The above two lenses (12) represent a left lens (121) located on the left and a right lens (122) located on the right.

[0049] Through two lenses (12), the user can view an image that is a mixture of the real environment and virtual objects.

[0050] The above lens cover (11) includes two openings (not designated), cover frame parts (111, 112) that surround the two openings respectively, and a central connecting part (113) that connects the cover frame parts (111, 112).

[0051] The lens cover (11) is formed by combining the front cover (11a), the rear cover (11b) and the lens bracket shown in Fig. 5.

[0052] The lens cover (11) can be divided into a cover frame portion (111, 112) on which the lens (12) is mounted and a central connecting portion (113) that connects the cover frame portions (111, 112).

[0053] The two openings are holes that penetrate the lens cover (11).

[0054] The two openings represent a left opening where the left lens (121) is placed and a right opening where the right lens (122) is placed.

[0055] The cover frame (111, 112) includes a left frame (111) surrounding the left opening (or left lens (121)) and a right frame (112) surrounding the right opening (or right lens (122)).

[0056] The central connecting portion (113) is located between the left edge portion (111) and the right edge portion (112), and connects the left edge portion (111) and the right edge portion (112).

[0057] Each of the left edge portion (111), the right edge portion (112) and the central connecting portion (113) includes one side and the other side opposite to the one side.

[0058] In Fig. 9, with respect to the left-right direction, one side (111a) of the left edge portion (111) is located on the right side of the left edge portion (111), and the other side (111b) of the left edge portion (111) is located on the left side of the left edge portion (111). In addition, one side (112a) of the right edge portion (112) is located on the left side of the right edge portion (112), and the other side (112b) of the right edge portion (112) is located on the right side of the right edge portion (112). In addition, one side (not assigned a symbol) of the central connection portion (113) is located on the left side of the central connection portion (113), and the other side (not assigned a symbol) of the central connection portion (113) is located on the right side of the central connection portion (113).

[0059] The above two temples (13) are hung on the user's ears when the smart glasses (1) are worn on the user's face.

[0060] The two temples (13) are composed of a left temple (131) connected to the left edge (111) and a right temple (132) connected to the right edge (112).

[0061] One side (111a) of the left edge portion (111) is connected to one side of the central connecting portion (113), and the other side (111b) of the left edge portion (111) is connected to the left temple (131).

[0062] One side (112a) of the right edge portion (112) is connected to the other side of the central connecting portion (113), and the other side (112b) of the right edge portion (112) is connected to the right temple (132).

[0063] The left temple (131) is formed by combining the left one-sided temple (131a) and the left other-sided temple (131b) shown in Fig. 5.

[0064] A space is formed inside the left temple (131), and a printed circuit board (1312), a speaker (not shown), a battery, wires, etc. can be placed in the space. Here, the printed circuit board (1312) may include a flexible printed circuit board (Flexible PCB, FPCB) according to an example of the embodiment.

[0065] Additionally, the right temple (132) is formed by combining the right one-sided temple (132a) and the right other-sided temple (132b) shown in FIG. 5.

[0066] A space is formed inside the right temple (132), and a printed circuit board assembly (PCB Assembly) (1323), a speaker (not shown), a battery (1324), wires, etc. can be placed in the space. Here, the printed circuit board assembly (1323) may include a flexible printed circuit board (FPCB), according to an example of an embodiment.

[0067] Each of the two temples (13) is rotatably connected to a lens cover (11) (specifically, a cover frame (111, 112)). The connection method may use a hinge (1311, 1321) as illustrated in Fig. 5, or any other conventional device (or technique). A detailed description of the connection method is omitted.

[0068] In order for the smart glasses (1) to be accommodated in the charging case (2), the temples (13) of the smart glasses (1) must be in a folded state.

[0069] Figures 3 and 4 show a state in which the temple (13) is folded. The fact that the temple (13) is in a folded state means that the temple (13) is rotated in one direction and positioned adjacent to the lens cover (11) (specifically, the cover frame portion (111, 112)). In this state, the longitudinal direction of the temple (13) and the longitudinal direction of the cover frame portion (111, 112) are arranged approximately parallel.

[0070] Additionally, in order for a user to wear the smart glasses (1) on their face, the temples (13) of the smart glasses (1) must be in an unfolded state.

[0071] Fig. 5 is an exploded perspective view of the smart glass (1) with the temple (13) unfolded. The temple (13) being in the unfolded state means that one end of the temple (13) is rotated in the opposite direction to the above-described one direction and is positioned away from the lens cover (11) (specifically, the cover frame portion (111, 112)). In this state, the longitudinal direction of the temple (13) and the longitudinal direction of the cover frame portion (111, 112) are approximately orthogonal.

[0072] A charging pin (14) (see Fig. 4) is arranged in the smart glass (1) of the present invention.

[0073] The charging pin (14) is formed of an electrical conductor and typically represents a contact terminal through which electricity flows.

[0074] Electricity supplied from the outside is transmitted to the charging pin (14) and stored in the built-in battery (1324) electrically connected to the charging pin (14).

[0075] Referring to Fig. 4, the charging pin (14) is arranged on the lower surface of the other side (112b) (or edge) of the right edge portion (112) and is exposed to the outside of the smart glass (1). According to another embodiment of the present invention, the charging pin (14) may also be arranged on the lower surface of the other side (111b) (or edge) of the left edge portion (111).

[0076] Referring to Fig. 5, the charging pin (14) is built into and supported by a charging pin bracket (1322) built into the other side (112b) of the right edge portion (112). According to an example of the embodiment, the charging pin bracket (1322) may not be manufactured separately, but may be formed integrally within the right edge portion (112).

[0077] The charging pin (14) comes into contact with the pogo pin (224) (see Fig. 7) placed in the charging case (2) and receives electricity from the battery built into the charging case (2).

[0078] In Fig. 5, reference numeral 114 indicates a metal accommodated in the central connecting portion (113) of the lens cover (11). The metal indicates a metal having the property of being attracted to the magnetic field of a magnet.

[0079] Drawing symbol 115 is a pad. When the smart glasses (1) are worn on the user's face, the pad (115) comes into contact with the user's nose.

[0080] Charging Case (2)

[0081] Figures 6 and 7 illustrate a charging case (2) of the present invention. Figure 7 (a) is a perspective view showing the charging case (2) in an open state, and Figure 7 (b) is a plan view of the charging case (2) illustrated in (a).

[0082] The charging case (2) accommodates and stores the smart glasses (1) and charges the accommodated smart glasses (1).

[0083] The external shape of the charging case (2), specifically the external shapes of the upper case (21)(21) and the lower case (22)(22) described later, are not limited to a specific shape.

[0084] The charging case (2) consists of an upper case (21) and a lower case (22).

[0085] The upper case (21) and the lower case (22) are coupled (connected) so as to be able to rotate relative to each other.

[0086] Specifically, one side of the upper case (21) (e.g., the rear side in FIG. 7) and one side of the lower case (22) (e.g., the rear side in FIG. 7) are coupled to each other so as to be able to rotate relative to each other.

[0087] The upper case (21) and / or the lower case (22) may include a hinge structure that allows one side of the upper case (21) and one side of the lower case (22) to be coupled to each other so that they can rotate relative to each other, and may further include other components.

[0088] The above hinge structure can be briefly described as follows.

[0089] Figure 6 illustrates several hinges (H1, H2, H3).

[0090] Among several hinges (H1, H2, H3), the first hinge (H1) and the second hinge (H1) are fastened to the upper case (21), and the third hinge (H3) is fastened to the lower case (22). In addition, one side of the first hinge (H1) and one side of the second hinge (H2) are connected to one side of the third hinge (H3) by a fitting fastening method, a bolt / nut fastening method, a screw fastening method, or the like.

[0091] The upper case (21) and the lower case (22) are rotatably coupled to each other using a first hinge (H1), a second hinge (H2), and a third hinge (H3). Since the relative rotation method using a hinge structure corresponds to a known technology, a detailed description thereof is omitted.

[0092] The above hinges (H1, H2, H3) can be the rotational center axis of the upper case (21) and / or the lower case (22).

[0093] The other side of the upper case (21) (e.g., the front side in FIG. 7) can rotate in one direction with one side of the upper case (21) (e.g., the rear side in FIG. 7) as the rotational center axis, and the other side of the lower case (22) (e.g., the front side in FIG. 7) can rotate in the opposite direction with one side of the lower case (22) (e.g., the rear side in FIG. 7) as the rotational center axis.

[0094] When the edges of the upper case (21) and the edges of the lower case (22) are in contact, the charging case (2) can be expressed as being closed. And, when the edges of the upper case (21) and the edges of the lower case (22) are separated, the charging case (2) can be expressed as being open.

[0095] When the other side of the upper case (21) rotates in one direction with one side of the upper case (21) as the rotational center axis while the edge of the upper case (21) and the edge of the lower case (22) are in contact (i.e., the charging case (2) is closed), the edge of the upper case (21) and the edge of the lower case (22) are separated.

[0096] And, when the edge of the upper case (21) and the edge of the lower case (22) are spaced apart (i.e., the charging case (2) is open), and the other side of the upper case (21) rotates in the opposite direction with one side of the upper case (21) as the rotational center axis, the edge of the upper case (21) and the edge of the lower case (22) come into contact.

[0097] A recess is formed inside each of the upper case (21) and the lower case (22). A space is formed inside each of the upper case (21) and the lower case (22) by the recess.

[0098] When the charging case (2) is closed, the groove formed in the upper case (21) and the groove formed in the lower case (22) are connected to each other and form a single internal space. The smart glass (1) is placed in the internal space.

[0099] When the charging case (2) is open, the groove formed in the upper case (21) and the groove formed in the lower case (22) are separated, and each groove is exposed (opened) to the outside.

[0100] When the charging case (2) is open, the smart glass (1) can be placed into a groove formed in the lower case (22) or taken out of the charging case (2) from the groove formed in the lower case (22).

[0101] <Upper case (21)>

[0102] The upper case (21) serves as a cover that covers the groove formed in the lower case (22).

[0103] Additionally, the upper case (21) accommodates a portion (e.g., the upper portion) of the smart glass (1).

[0104] Specifically, when the smart glass (1) is accommodated in the charging case (2), a part (e.g., the upper part) of the smart glass (1) is accommodated in the upper case (21), and the remaining part (e.g., the lower part) of the smart glass (1) is accommodated in the lower case (22).

[0105] The upper case (21) includes an upper outer case (211) and an upper inner case (212).

[0106] The upper outer case (211) and the upper inner case (212) each have an outer surface and an inner surface.

[0107] The outer surface of the upper outer case (211) is exposed to the outside of the charging case (2), the inner surface of the upper outer case (211) and the outer surface of the upper inner case (212) face each other, and the inner surface of the upper inner case (212) faces the lower case (22).

[0108] The upper outer case (211) and the upper inner case (212) are manufactured separately and can be joined together. The joining can be done by an adhesive or a forced fit method, or by fastening members such as bolts, nuts, screws, etc.

[0109] The upper case (21) (upper outer case (211) and upper inner case (212)) has a preset length in one direction (e.g., left-right direction in FIG. 6), a preset width in another direction (front-back direction in FIG. 6), and a preset height in another direction (up-down direction in FIG. 6). Here, the one direction, the other direction, and the other direction represent a conventional three-dimensional rectangular coordinate system.

[0110] The upper case (21) (upper outer case (211) and upper inner case (212)) has a groove. The groove may be named a 'first groove'.

[0111] If the opening of the first groove formed in the upper case (21) faces downward as shown in FIG. 6, the first groove is formed by being sunken from the lower side to the upper side along the edge of the upper case (21) (upper outer case (211) and upper inner case (212)) to a preset depth.

[0112] In other words, if the opening of the first groove formed in the upper case (21) faces upward, the first groove is formed by being sunken from the upper side to the lower side along the edge of the upper case (21) to a preset depth.

[0113] When the smart glass (1) is placed in the groove formed in the lower case (22), the portion of the smart glass (1) that is exposed to the outside of the groove of the lower case (22) is accommodated in the first groove of the upper case (21).

[0114] Accordingly, according to an example of the embodiment, the shape of the first groove of the upper case (21) can be formed to correspond to the shape of the smart glass (1) accommodated in the first groove. As a result, the movement of the smart glass (1) is limited, so that the smart glass (1) can be continuously charged without interruption, and can be prevented from being damaged even if an impact is applied to the charging case (2).

[0115] The upper outer case (211) accommodates the upper inner case (212). In other words, the upper inner case (212) is accommodated in the first groove formed in the upper outer case (211).

[0116] The first groove (not marked) of the upper outer case (211) and the first groove (2121) of the upper inner case (212) (see Fig. 7) may be formed in the same shape or may be formed in different shapes.

[0117] For example, the first groove of the upper outer case (211) and the first groove (2121) of the upper inner case (212) can be formed in shapes corresponding to each other.

[0118] Alternatively, the first groove of the upper outer case (211) and the first groove (2121) of the upper inner case (212) may be formed in non-corresponding shapes.

[0119] Specifically, the preset depth of the first groove of the upper outer case (211) and the preset depth of the first groove (2121) of the upper inner case (212) may be different.

[0120] Alternatively, the first groove (2121) of the upper inner case (212) may include a shape corresponding to the shape of the smart glass (1) accommodated in the first groove (2121), but the first groove of the upper outer case (211) may not include a shape corresponding to the shape of the smart glass (1).

[0121] Alternatively, the outer surface of the upper inner case (212) may include a shape such as a curve, a groove, or a step, for example, to reduce the weight of the charging case (2). Accordingly, one or more spaces of a preset volume may be formed between the inner surface of the upper outer case (211) and the outer surface of the upper inner case (212).

[0122] When the charging case (2) is closed, the edges of the upper case (21) and the edges of the lower case (22) face each other.

[0123] When the charging case (2) is closed, the edges of the upper case (21) and the edges of the lower case (22) are in contact with each other. At this time, the edges of the upper case (21) and the edges of the lower case (22) may include components such as a noise (or shock) prevention pad or tape.

[0124] Specifically, when the charging case (2) is closed, the rim of the upper outer case (211) surrounding the first groove of the upper outer case (211) can come into contact with the rim of the lower outer case (221) surrounding the second groove (2211) of the lower outer case (221) (see FIG. 6) described later.

[0125] And, the rim of the upper inner case (212) surrounding the first groove (2121) of the upper inner case (212) can come into contact with the rim of the lower inner case (222) surrounding the second groove (2221) of the lower inner case (222) described later.

[0126] For example, the upper inner case (212) includes a front edge (unsigned), a rear edge (unsigned), a left edge (unsigned), and a right edge (unsigned). In addition, the lower inner case (222), which will be described later, includes a front edge (222a), a rear edge (222b), a left edge (222c), and a right edge (222d). Here, the front side, the rear side, the left side, and the right side reflect the coordinate system illustrated in FIG. 7.

[0127] When the charging case (2) is closed, the front edge of the upper inner case (212) faces the front edge (222a) of the lower inner case (222), the rear edge of the upper inner case (212) faces the rear edge (222b) of the lower inner case (222), the left edge of the upper inner case (212) faces the left edge (222c) of the lower inner case (222), and the right edge of the upper inner case (212) faces the right edge (222d) of the lower inner case (222).

[0128] <Subcase (22)>

[0129] The lower case (22) accommodates a portion (e.g., the lower portion) of the smart glass (1). In addition, the lower case (22) accommodates components that allow the smart glass (1) to be charged.

[0130] The lower case (22) includes a lower outer case (221) and a lower inner case (222).

[0131] The lower outer case (221) and the lower inner case (222) each have an outer surface and an inner surface.

[0132] The outer surface of the lower outer case (221) is exposed to the outside of the charging case (2), the inner surface of the lower outer case (221) and the outer surface of the lower inner case (222) face each other, and the inner surface of the lower inner case (222) faces the upper case (21).

[0133] The lower outer case (221) and the lower inner case (222) are manufactured separately and can be joined together. The joining can be done by an adhesive or a forced fit method, or by fastening members such as bolts, nuts, screws, etc.

[0134] The lower case (22) (lower outer case (221) and lower inner case (222)) has a preset length in one direction (e.g., left-right direction in FIG. 6), a preset width in another direction (front-back direction in FIG. 6), and a preset height in another direction (up-down direction in FIG. 6).

[0135] The lower case (22) (lower outer case (221) and lower inner case (222)) has grooves (2211, 2221). The grooves (2211, 2221) may be referred to as 'second grooves'.

[0136] If the opening of the second groove (2211, 2221) formed in the lower case (22) faces upward as shown in FIG. 6, the second groove (2211, 2221) is formed by recessing from the upper side to the lower side along the edge of the lower case (22) (lower outer case (221) and lower inner case (222)) to a preset depth.

[0137] When the smart glass (1) is placed in the second groove (2211, 2221) of the lower case (22), a part (e.g., the lower part) of the smart glass (1) is accommodated in the second groove (2211, 2221).

[0138] The lower outer case (221) accommodates the lower inner case (222). In other words, the lower inner case (222) is accommodated in the second groove (2211) formed in the lower outer case (221).

[0139] The second groove (2211) of the lower outer case (221) and the second groove (2221) of the lower inner case (222) are formed in different shapes.

[0140] For example, the second groove (2211) of the lower outer case (221) and the second groove (2221) of the lower inner case (222) may be formed in non-corresponding shapes.

[0141] The second groove (2221) of the lower inner case (222) may have a shape corresponding to the shape of the smart glass (1) accommodated in the second groove (2221), but the second groove (2211) of the lower outer case (221) may not have a shape corresponding to the shape of the smart glass (1).

[0142] In addition, one or more spaces of a preset volume may be formed between the outer surface of the lower inner case (222) and the inner surface of the lower outer case (221). A hardware assembly (226), a lighting element (LED) (227), a magnetic element (223), etc. may be placed in the one or more spaces. The hardware assembly (226) includes a battery, a substrate, other electrical and electronic devices, etc.

[0143] Below, the shape of the second groove (2221) formed in the lower inner case (222) is described in detail.

[0144] The shape of the second groove (2221) of the lower inner case (222) can be formed to correspond to the shape of the smart glass (1) accommodated in the second groove (2221). As a result, the movement of the smart glass (1) is limited, so that the smart glass (1) can be continuously charged without interruption, and can be prevented from being damaged even if an impact is applied to the charging case (2).

[0145] The second groove (2221) of the lower inner case (222) is a groove that accommodates a part (e.g., a lower part) of the smart glass (1). Here, the part of the smart glass (1) refers to a lower part including the middle part of the lens (12) when the lens (12) is placed vertically (e.g., in the up-down direction in FIG. 9), or refers to a lower part of the temple (13).

[0146] If the opening of the second groove (2221) of the lower inner case (222) faces upward as shown in FIGS. 6 and 7, the second groove (2221) is formed by being sunken from the upper side to the lower side along the edge of the lower inner case (222) to a preset depth.

[0147] The second groove (2221) of the lower inner case (222) has a preset length in one direction (e.g., left-right direction in FIG. 7), a preset width in another direction (front-back direction in FIG. 7), and a preset depth in another direction (up-down direction in FIG. 7).

[0148] The lower inner case (222) includes a left support (2222) and a left protrusion (2222p).

[0149] The left support (2222) and the left protrusion (2222p) are formed in the second groove (2221) of the lower inner case (222).

[0150] The left support portion (2222) supports the edge of the left edge portion (111) of the smart glass (1) from below when the smart glass (1) is accommodated in the second groove (2221) of the lower inner case (222). The edge of the left edge portion (111) specifically refers to the edge of the other side (111b) of the left edge portion (111) (see FIG. 9).

[0151] The left support (2222) is formed on one side of the second groove (2221). Here, one side of the second groove (2221) represents the front left edge (see Fig. 7) of the second groove (2221).

[0152] The left support portion (2222) is formed to protrude from the bottom surface of the second groove (2221) toward the opening (e.g., the upper side in FIG. 7) of the second groove (2221) at a preset height. Here, the preset height is determined as a height capable of supporting the edge of the left edge portion (111) of the smart glass (1) from below when the smart glass (1) is accommodated in the second groove (2221) of the lower inner case (222).

[0153] The left protrusion (2222p) is formed on the left support (2222).

[0154] The left protrusion (2222p) is formed on one side (e.g., the left side in FIG. 7) of the upper surface of the left support (2222).

[0155] The left protrusion (2222p) is formed to protrude from the upper surface of the left support (2222) toward the upper case (21) side (e.g., the upper side in FIG. 7) at a preset height. Here, the preset height protrudes higher than the height of the opening of the second groove (2221). However, when the charging case (2) is closed, the left protrusion (2222p) is accommodated in the groove of the upper case (21), so that the rim of the upper case (21) and the rim of the lower case (22) are in contact with each other.

[0156] Specifically, when the smart glass (1) is accommodated in the second groove (2221) of the lower inner case (222), the left protrusion (2222p) is arranged adjacent to (or adjacent to) the side of the edge of the left edge portion (111) of the smart glass (1) (see FIG. 9). Here, the edge of the left edge portion (111) specifically refers to the edge of the other side (111b) of the left edge portion (111). Accordingly, the left protrusion (2222p) restricts the smart glass (1) from moving to the left, for example, in FIG. 9.

[0157] In addition, when the smart glass (1) is seated in the second groove (2221) of the lower inner case (222), the left protrusion (2222p) guides the edge of the left edge (111) of the smart glass (1) to be seated in the left support (2222).

[0158] In summary, the left support (2222) is positioned below the edge of the left edge (111) of the smart glass (1), and supports the edge of the left edge (111) from below.

[0159] In addition, the left protrusion (2222p) is positioned at a preset distance from the side of the edge of the left edge portion (111), thereby guiding the edge of the left edge portion (111) to be seated on the left support portion (2222).

[0160] The lower inner case (222) includes a right support portion (2223), a pogo pin mounting portion (2223p1), and a right protrusion portion (2223p2).

[0161] (a) of Fig. 10 is an enlarged perspective view of the right support portion (2223), the pogo pin mounting portion (2223p1), and the right protrusion portion (2223p2) in the lower inner case (222), and (b) is a cross-sectional view showing the contact relationship between the pogo pin (224) positioned on the pogo pin mounting portion (2223p1) and the charging pin (14) positioned on the smart glass (1).

[0162] The right support part (2223) and the right protrusion part (2223p2) are formed in the second groove (2221) of the lower inner case (222).

[0163] The right support portion (2223) supports the edge of the right edge portion (112) of the smart glass (1) from below when the smart glass (1) is accommodated in the second groove (2221) of the lower inner case (222). The edge of the right edge portion (112) specifically refers to the edge of the other side (112b) of the right edge portion (112) (see FIG. 9).

[0164] The right support portion (2223) is formed on the other side of the second groove (2221). Here, the other side of the second groove (2221) represents the front right edge (see Fig. 7) of the second groove (2221). That is, one side and the other side of the second groove (2221) represent opposite directions.

[0165] The right support portion (2223) is formed to protrude from the bottom surface of the second groove (2221) toward the opening (e.g., the upper side in FIG. 7) of the second groove (2221) at a preset height. Here, the preset height may be determined as a height capable of supporting the edge of the right edge portion (112) of the smart glass (1) from below when the smart glass (1) is accommodated in the second groove (2221) of the lower inner case (222).

[0166] The pogo pin mounting portion (2223p1) is formed on the right support portion (2223).

[0167] The pogo pin mounting portion (2223p1) is formed on one edge (e.g., the left edge in FIG. 7) of the upper surface of the right support portion (2223). For reference, the right protrusion portion (2223p2) described below is formed on the other edge (e.g., the right edge in FIG. 7) of the upper surface of the right support portion (2223).

[0168] The pogo pin mounting portion (2223p1) includes a plurality of holes. The plurality of holes are formed through the upper surface of the right support portion (2223) and are formed toward the upper case (21) side (e.g., the upper side in FIG. 7).

[0169] A pogo pin (224) is positioned to penetrate each of the plurality of holes formed in the pogo pin mounting portion (2223p1). One end of the pogo pin (224) penetrates the plurality of holes and is exposed to the outside.

[0170] The edge of the pogo pin mounting portion (2223p1) is formed to be round. This facilitates contact with the pogo pin (224).

[0171] The pogo pin (224) of the present invention is formed of a conductor and includes a conventional electrically conductive contact terminal. The pogo pin (224) is electrically connected to the battery built into the charging case (2).

[0172] When the smart glass (1) is placed in the second groove (2221) of the lower inner case (222), one end of the pogo pin (224) comes into contact with the charging pin (14) placed in the smart glass (1). As a result, the battery (1324) built into the smart glass (1) is charged.

[0173] When the smart glass (1) is seated in the second groove (2221) of the lower inner case (222), the pogo pin seating portion (2223p1) and the pogo pin (224) are formed at positions corresponding to the charging pin (14) positioned on the smart glass (1). At this time, the pogo pin seating portion (2223p1) and the pogo pin (224) are positioned below, and the charging pin (14) of the smart glass (1) is positioned above, and they come into contact with each other.

[0174] The pogo pin (224) is supported by a pogo pin bracket (225) placed inside the right support member (2223) (see (b) of FIG. 10).

[0175] The right protrusion (2223p2) is formed on the right support (2223).

[0176] The right protrusion (2223p2) is formed on the other side (e.g., the right side in FIG. 7) of the upper surface of the right support portion (2223). The right protrusion (2223p2) is formed at a preset distance from the pogo pin mounting portion (2223p1) on the upper surface of the right support portion (2223).

[0177] The right protrusion (2223p2) is formed to protrude from the upper surface of the right support (2223) toward the upper case (21) side (e.g., the upper side in FIG. 7) at a preset height. Here, the preset height protrudes upwards above the height of the opening of the second groove (2221). However, when the charging case (2) is closed, the right protrusion (2223p2) is accommodated in the groove of the upper case (21), so that the rim of the upper case (21) and the rim of the lower case (22) are in contact with each other.

[0178] Specifically, when the smart glass (1) is accommodated in the second groove (2221) of the lower inner case (222), the right protrusion (2223p2) is arranged adjacent to (or adjacent to) the side of the edge of the right edge portion (112) of the smart glass (1) (see FIG. 9). Here, the edge of the right edge portion (112) specifically refers to the edge of the other side (112b) of the right edge portion (112). Accordingly, the right protrusion (2223p2) restricts the smart glass (1) from moving to the right, for example, in FIG. 9.

[0179] In addition, when the smart glass (1) is seated in the second groove (2221) of the lower inner case (222), the right protrusion (2223p2) guides the edge of the right edge (112) of the smart glass (1) to be seated in the right support (2223).

[0180] In summary, the right support part (2223) is positioned below the edge of the right edge part (112) of the smart glass (1), and supports the edge of the right edge part (112) from below.

[0181] In addition, the right protrusion (2223p2) is positioned at a preset distance from the side of the edge of the right edge portion (112), thereby guiding the edge of the right edge portion (112) to be seated on the right support portion (2223).

[0182] The lower inner case (222) includes a front central support (2224) and a magnet member receiving portion (2224d).

[0183] The front central support (2224) and the magnet member receiving portion (2224d) are formed in the second groove (2221) of the lower inner case (222).

[0184] When the smart glass (1) is installed in the second groove (2221) of the lower inner case (222), the front central support (2224) is positioned below the central connecting portion (113) of the smart glass (1) and supports the central connecting portion (113) from below.

[0185] The front central support (2224) is formed in the front and center of the second groove (2221). Here, the front indicates the front side in Fig. 7, and the center indicates the center of the left and right sides in Fig. 7.

[0186] The front central support (2224) is formed to protrude from the bottom surface of the second groove (2221) toward the opening (e.g., the upper side in FIG. 7) of the second groove (2221) at a preset height.

[0187] The front central support (2224) includes an upper surface (2224c) and two side surfaces. Here, the upper surface (2224c) represents the uppermost surface when the front central support (2224) is formed by protruding from the bottom surface of the second groove (2221) at a preset height.

[0188] And, the two sides represent sides formed on one side (e.g., the left side in FIG. 7) and the other side (e.g., the right side in FIG. 7) of the front central support (2224), respectively.

[0189] The side formed on one side of the front central support (2224) may be named a 'central one-side support (2224a)', and the side formed on the other side of the front central support (2224) may be named a 'central other-side support (2224b)'.

[0190] The central one-sided support (2224a) is located on one side (e.g., the left side in FIG. 7) of the upper surface (2224c), and the central other-sided support (2224b) is located on the other side (e.g., the right side in FIG. 7) of the upper surface (2224c).

[0191] The central one-sided support (2224a), the upper surface (2224c), and the central other-sided support (2224b) are connected from one side to the other side (for example, from left to right in FIG. 7).

[0192] The central one-sided support (2224a) and the central other-sided support (2224b) are formed to face each other based on the upper surface (2224c).

[0193] The central one-sided support portion (2224a) is formed to be inclined at a preset angle from one side (e.g., the left side in FIG. 7) of the upper surface (2224c) toward the bottom (e.g., the lower side in FIG. 7). In other words, the central one-sided support portion (2224a) becomes closer to the left edge (222c) of the lower inner case (222) toward the bottom from one side of the upper surface (2224c).

[0194] The central other-side support portion (2224b) is formed to be inclined at a preset angle from the other side (e.g., the right side in FIG. 7) of the upper surface (2224c) toward the lower side (e.g., the lower side in FIG. 7). In other words, the central other-side support portion (2224b) becomes closer to the right edge (222d) of the lower inner case (222) toward the lower side from the other side of the upper surface (2224c) toward the lower side.

[0195] When the smart glass (1) is installed in the second groove (2221) of the lower inner case (222), the central one-side support (2224a) can support the left edge (111) of the smart glass (1) adjacent to the central one-side support (2224a) from one side. In addition, the central other-side support (2224b) can support the right edge (112) of the smart glass (1) adjacent to the central other-side support (2224b) from the other side. As a result, the movement of the smart glass (1) to one side or the other side (for example, the left or right in FIG. 7) is restricted. Even if an external force is applied to the charging case (2), the smart glass (1) continues to be charged without interruption.

[0196] When the front central support (2224) protrudes from the bottom surface of the second groove (2221) toward the opening of the second groove (2221) (for example, the upper side in FIG. 7) to a preset height, a groove corresponding to the protruded volume is formed below the second groove (2221) of the lower inner case (222). In other words, the groove is formed by recessing from the lower side to the upper side in FIG. 7 at the position where the front central support (2224) is formed in the lower inner case (222). The groove forms a space between the outer surface of the lower inner case (222) and the inner surface of the lower outer case (221). A separate component, such as a component that supports and fixes the magnet member (223), may be placed in the groove (space).

[0197] The magnet member receiving portion (2224d) is formed on the upper surface (2224c) of the front central support portion (2224).

[0198] The magnet member receiving portion (2224d) is formed to protrude from the upper surface (2224c) of the front central support portion (2224) toward the upper case (21) side (e.g., the upper side in FIG. 7) at a preset height. Here, the preset height may protrude upwards higher than the height of the opening of the second groove (2221). However, when the charging case (2) is closed, the magnet member receiving portion (2224d) is received in the groove of the upper case (21), so that the rim of the upper case (21) and the rim of the lower case (22) are in contact with each other.

[0199] When the smart glass (1) is installed in the second groove (2221) of the lower inner case (222), the magnet member receiving portion (2224d) supports the central connecting portion (113) of the smart glass (1) from below. The front central support portion (2224) supports the central connecting portion (113) of the smart glass (1) from below via the magnet member receiving portion (2224d).

[0200] The magnet member receiving portion (2224d) receives the magnet member (223).

[0201] When the magnet member receiving portion (2224d) protrudes from the upper surface (2224c) of the front central support portion (2224) toward the upper case (21) side (e.g., the upper side in FIG. 7) to a preset height, a groove corresponding to the protruded volume is formed below the second groove (2221) of the lower inner case (222). In other words, the groove is formed by recessing from the lower side to the upper side in FIG. 7 at the position where the magnet member receiving portion (2224d) is formed in the lower inner case (222) to a preset depth (height). A magnet member (223) is placed in the groove.

[0202] The magnet member (223) may be inserted and fixed into the magnet member receiving portion (2224d) in a forced fit manner. Alternatively, a separate component that supports and fixes the magnet member (223) may be placed under the magnet member (223).

[0203] The magnet member (223) is inserted and placed in the magnet member receiving portion (2224d).

[0204] A metal member (114) or another magnetic member that is attracted to the magnetic force of the magnet member (223) may be placed inside the central connecting portion (113) of the smart glass (1) supported by the magnet member receiving portion (2224d). Alternatively, the central connecting portion (113) itself may be manufactured (formed) from a metal that is attracted to the magnetic force of the magnet member (223).

[0205] Since smart glasses (1) are worn on the user's face, their weight needs to be reduced. Considering this, it is preferable that the central connecting portion (113) be made of a metal that is itself attracted to the magnetic force of the magnetic member (223). Furthermore, it is preferable that the central connecting portion (113) be formed of a metal material that is lightweight, highly magnetic, and highly rigid.

[0206] When the smart glass (1) is placed in the second groove (2221) of the lower inner case (222), the central connecting portion (113) of the smart glass (1) is fixed by contact with the magnet member receiving portion (2224d) of the lower inner case (222) by the magnetic force of the magnet member (223). As a result, the smart glass (1) is restricted from moving forward and backward, left and right, and up and down, and even if an external force is applied to the charging case (2), the smart glass (1) continues to be charged without interruption.

[0207] The shape of the upper surface of the magnet member receiving portion (2224d) may correspond to the shape of the central connecting portion (113) of the smart glass (1) that is seated on and in contact with the magnet member receiving portion (2224d). Accordingly, the movement of the smart glass (1) may be further restricted.

[0208] According to an example of an embodiment of the present invention, the magnet member receiving portion (2224d) may further include a front protrusion portion (2224p).

[0209] The front protrusion (2224p) is formed on the upper surface of the magnet member receiving portion (2224d).

[0210] The front protrusion (2224p) is formed in a portion of the upper surface of the magnet member receiving portion (2224d). Specifically, the front protrusion (2224p) is formed on the front edge (222a) side of the lower inner case (222) on the upper surface of the magnet member receiving portion (2224d).

[0211] Alternatively, according to an example of the embodiment, the front protrusion (2224p) may be formed on a portion of the upper surface of the magnet member receiving portion (2224d) and the front edge (222a) of the lower inner case (222).

[0212] The front protrusion (2224p) is formed to protrude from the upper surface of the magnet member receiving portion (2224d) toward the upper case (21) side (for example, the upper side in FIG. 7) at a preset height. Here, the preset height protrudes higher than the height of the opening of the second groove (2221). However, when the charging case (2) is closed, the front protrusion (2224p) is received in the groove of the upper case (21), so that the rim of the upper case (21) and the rim of the lower case (22) are in contact with each other.

[0213] When the front protrusion (2224p) protrudes from the upper surface of the magnet member receiving portion (2224d) toward the upper case (21) side (for example, the upper side in FIG. 7) to a preset height, a groove corresponding to the protruded volume is formed below the second groove (2221) of the lower inner case (222). In other words, the groove is formed by recessing from the lower side to the upper side in FIG. 7 at the position where the front protrusion (2224p) is formed in the lower inner case (222) to a preset depth (height). A part of the magnet member (223) received in the magnet member receiving portion (2224d) can be placed in the groove.

[0214] When the smart glass (1) is seated in the second groove (2221) of the lower inner case (222), the central connecting portion (113) of the smart glass (1) is seated on the upper surface of the magnet member receiving portion (2224d). At this time, the central connecting portion (113) of the smart glass (1) is restricted from moving forward by the front protrusion (2224p). In addition, the smart glass (1) is firmly fixed by the magnet member (223) arranged in the magnet member receiving portion (2224d) and the front protrusion (2224p).

[0215] The lower inner case (222) includes a rear central support (2225) and a rear protrusion (2225p).

[0216] The rear central support (2225) and the rear protrusion (2225p) are formed in the second groove (2221) of the lower inner case (222).

[0217] When the smart glass (1) is accommodated in the second groove (2221) of the lower inner case (222), the rear central support (2225) supports the temple (13) of the smart glass (1) from below. At this time, the temple (13) is folded in the smart glass (1).

[0218] The rear central support (2225) is formed at the rear and center of the second groove (2221). Here, the rear indicates the rear side in FIG. 7, and the center indicates the center of the left and right sides in FIG. 7.

[0219] The rear center support (2225) is positioned on the rear side of the front center support (2224) (see Fig. 7).

[0220] The rear central support (2225) is formed to protrude from the bottom surface of the second groove (2221) toward the opening (e.g., the upper side in FIG. 7) of the second groove (2221) at a preset height. Here, the preset height may be determined as a height capable of supporting the temple (13) of the smart glass (1) from below when the smart glass (1) is accommodated in the second groove (2221) of the lower inner case (222).

[0221] The protruding shape of the rear central support (2225) can be formed into an English alphabet T shape when looking down at the lower inner case (222) from above (for example, from the top to the bottom in FIG. 7). Here, the T shape includes not only a T shape but also a similar shape.

[0222] Specifically, the rear central support (2225) can be divided into a temple support (2225a) and a rear protrusion support (2225b).

[0223] The temple support (2225a) and the rear protrusion support (2225b) are formed as one piece and connected to each other.

[0224] The temple support (2225a) has a preset length in the first direction.

[0225] The above first direction represents one side and the other side (e.g., the left and right directions in FIG. 7) or represents the longitudinal direction of the lower inner case (222).

[0226] And the preset length of the temple support (2225a) also has a preset width.

[0227] The temple support (2225a) is formed at the rear and center of the second groove (2221).

[0228] The temple support (2225a) is positioned below the temple (13) of the smart glass (1) and supports the temple (13) from below. That is, the temple of the smart glass (1) is placed on the upper surface of the temple support (2225a).

[0229] The temple support (2225a) has a side facing the front center support (2224) (which may be referred to as the 'temple support side (2225a1)').

[0230] The temple support side (2225a1) is partitioned by the rear protrusion support (2225b) described later. In other words, the temple support side (2225a1) is partitioned into a temple support one side (2225a11) located on one side (e.g., the left side in FIG. 7) of the rear protrusion support (2225b) based on the rear protrusion support (2225b) and a temple support other side (2225a12) located on the other side (e.g., the right side in FIG. 7) of the rear protrusion support (2225b).

[0231] One side of the temple support (2225a11) and the other side of the temple support (2225a12) are formed to face each other based on the rear protrusion support (2225b).

[0232] The temple support side (2225a1) (one side of the temple support (2225a11) and the other side of the temple support (2225a12)) is formed to be inclined at a preset angle as it goes downward from one edge of the upper surface of the temple support (2225a).

[0233] In other words, the side surface (2225a1) of the temple support portion becomes closer to the front edge (222a) of the lower inner case (222) as it goes down from one edge of the upper surface of the temple support portion (2225a). Here, the one edge of the upper surface of the temple support portion (2225a) refers to the edge of the upper surface of the temple support portion (2225a) that faces the front edge (222a) of the lower inner case (222) among the edges of the upper surface of the temple support portion (2225a) (or is close to the front edge (222a)).

[0234] When the smart glass (1) is inserted into the second groove (2221) of the lower inner case (222), the temple support side (2225a1) serves to guide the smart glass (1) so that it is fixed in place.

[0235] Specifically, when the smart glass (1) is inserted into the second groove (2221) of the lower inner case (222), the temple support side (2225a1) guides the central connecting portion (113) of the smart glass (1) to be seated in the magnet member receiving portion (2224d) of the lower inner case (222), the edge of the left edge portion (111) of the smart glass (1) to be seated in the left support portion (2222) of the lower inner case (222), and the edge of the right edge portion (112) of the smart glass (1) to be seated in the right support portion (2223) of the lower inner case (222).

[0236] The rear protrusion support (2225b) is connected to the center of the temple support (2225a) in the longitudinal direction of the temple support (2225a), and has a preset length from the center of the temple support (2225a) toward the magnet member receiving portion (2224d).

[0237] In other words, one side of the rear protrusion support (2225b) is connected to the center of the temple support (2225a) in the longitudinal direction of the temple support (2225a), and the other side of the rear protrusion support (2225b) has a preset length in a direction orthogonal to the first direction (toward the magnet member receiving portion (2224d)).

[0238] The rear protrusion support member (2225b) is spaced apart from the magnet member receiving member (2224d) by a preset distance in the front-back direction.

[0239] The rear protrusion (2225p) is formed on the upper surface of the rear protrusion support (2225b).

[0240] The rear protrusion (2225p) is formed to protrude from the upper surface of the rear protrusion support (2225b) toward the upper case (21) side (e.g., the upper side in FIG. 7) at a preset height. Here, the preset height may protrude upwards higher than the height of the opening of the second groove (2221). However, when the charging case (2) is closed, the rear protrusion (2225p) is accommodated in the groove of the upper case (21), so that the rim of the upper case (21) and the rim of the lower case (22) are in contact with each other.

[0241] When the smart glass (1) is seated in the second groove (2221) of the lower inner case (222), the temple (13) of the smart glass (1) is placed on the temple support (2225a), and the rear protrusion (2225p) is placed between the central connecting portion (113) of the smart glass (1) and the temple (13) (see FIGS. 8 and 11). In other words, the two temples (13) of the smart glass (1) are placed between the rear protrusion (2225p) and the rear edge (222b) of the lower inner case (222).

[0242] The rear protrusion (2225p) restricts the movement of the smart glass (1).

[0243] Specifically, referring to FIGS. 11 and 12, when the smart glass (1) is seated in the second groove (2221) of the lower inner case (222), the magnet member (223) accommodated in the magnet member accommodation portion (2224d) of the lower inner case (222) attracts the central connecting portion (113) of the smart glass (1).

[0244] As a result, the smart glass (1) rotates in one direction (e.g., counterclockwise from the rear side to the front side in FIG. 12). At this time, the rear protrusion (2225p) restricts the temple (13) of the smart glass (1) from rotating in one direction. Due to the rear protrusion (2225p), the smart glass (1) is stably fixed to the second groove (2221) of the lower inner case (222).

[0245] When the rear central support (2225) protrudes from the bottom surface of the second groove (2221) toward the upper case (21) side (e.g., the upper side in FIG. 7) to a preset height, a groove corresponding to the protruded volume is formed below the second groove (2221) of the lower inner case (222). In other words, the groove is formed by recessing from the lower side to the upper side in FIG. 7 at a position where the rear central support (2225) is formed in the lower inner case (222). The groove forms a space between the outer surface of the lower inner case (222) and the inner surface of the lower outer case (221). A separate component, such as a hardware assembly (226) required for charging the smart glass (1), may be placed in the groove (space).

[0246] The lower inner case (222) includes a left lens support (2226) and a left lens fixing part (2227).

[0247] The left lens support (2226) and the left lens fixing part (2227) are formed in the second groove (2221) of the lower inner case (222).

[0248] The left lens support (2226) and the left lens fixing portion (2227) are formed to protrude from the bottom surface of the second groove (2221) of the lower inner case (222) toward the opening (e.g., the upper side in FIG. 7) of the second groove (2221) at a preset height.

[0249] The left lens support (2226) and the left lens fixing (2227) are formed with a preset length from the front edge (222a) side of the lower inner case (222) to the rear edge (222b) side.

[0250] The left lens support (2226) and the left lens fixing (2227) are connected in a row, and the protruding height of the left lens support (2226) is formed lower than the protruding height of the left lens fixing (2227).

[0251] Accordingly, a step is formed at the boundary area between the left lens support (2226) and the left lens fixing part (2227). That is, a step surface is formed between the upper surface of the left lens support (2226) and the upper surface of the left lens fixing part (2227).

[0252] The left lens support (2226) is adjacent to the front edge (222a) of the lower inner case (222), and the left lens fixing part (2227) is adjacent to the rear edge (222b) of the lower inner case (222).

[0253] The left lens support (2226) supports the left edge (111) of the lens cover (11) of the smart glass (1). The left lens fixing part (2227) restricts the left edge (111) of the lens cover (11) from rotating in one direction.

[0254] The left lens support (2226) supports the left edge portion (111) of the lens cover (11), thereby supporting the left lens (121) placed inside the left edge portion (111).

[0255] The left lens fixing member (2227) restricts the left edge portion (111) of the lens cover (11) from rotating in one direction, thereby restricting the left lens (121) positioned inside the left edge portion (111) from rotating in one direction.

[0256] In detail, when the smart glass (1) is accommodated in the second groove (2221) of the lower inner case (222), the left lens support (2226) is located below the left edge (111) of the lens cover (11) and supports the left edge (111) from below.

[0257] In detail, when the smart glass (1) is placed in the second groove (2221) of the lower inner case (222), the magnet member (223) placed in the magnet member receiving portion (2224d) of the lower inner case (222) attracts the central connecting portion (113) of the smart glass (1).

[0258] As a result, the smart glass (1) rotates in one direction (e.g., counterclockwise from the front side to the rear side in FIG. 12). At this time, the left lens fixing part (2227) is located on one side of the lower part of the left edge part (111) of the lens cover (11) to restrict the left edge part (111) from rotating in one direction.

[0259] When the left edge portion (111) of the lens cover (11) rotates in one direction, the lower end of the left edge portion (111) comes into contact with the step surface formed between the left lens support portion (2226) and the left lens fixing portion (2227). Accordingly, the left edge portion (111) is restricted from rotating in one direction. The smart glass (1) is stably fixed to the second groove (2221) of the lower inner case (222).

[0260] The lower inner case (222) includes a right lens support (2228) and a right lens fixing part (2229).

[0261] The right lens support (2228) is identical in function and shape to the previously described left lens support (2226) except for its location. The right lens fixing part (2229) is identical in function and shape to the previously described left lens fixing part (2227) except for its location.

[0262] Specifically, the right lens support (2228) is formed in a position opposite to and in a shape corresponding to the left lens support (2226) described above, based on the rear protrusion support (2225b). In addition, the right lens fixing part (2229) is formed in a position opposite to and in a shape corresponding to the left lens fixing part (2227) described above, based on the rear protrusion support (2225b).

[0263] The right lens support (2228) and the right lens fixing (2229) are formed in the second groove (2221) of the lower inner case (222).

[0264] The right lens support (2228) and the right lens fixing (2229) are formed to protrude from the bottom surface of the second groove (2221) of the lower inner case (222) toward the opening (e.g., the upper side in FIG. 7) of the second groove (2221) at a preset height.

[0265] The right lens support (2228) and the right lens fixing (2229) are formed with a preset length from the front edge (222a) side of the lower inner case (222) to the rear edge (222b) side.

[0266] The right lens support (2228) and the right lens fixing part (2229) are connected in a row, and the protruding height of the right lens support (2228) is formed lower than the protruding height of the right lens fixing part (2229).

[0267] Accordingly, a step is formed at the boundary area between the right lens support (2228) and the right lens fixing part (2229). That is, a step surface (22289) is formed between the upper surface of the right lens support (2228) and the upper surface of the right lens fixing part (2229) (see FIG. 12).

[0268] The right lens support (2228) is adjacent to the front edge (222a) of the lower inner case (222), and the right lens fixing part (2229) is adjacent to the rear edge (222b) of the lower inner case (222).

[0269] Referring to Fig. 12, the right lens support (2228) supports the right edge (112) of the lens cover (11) of the smart glass (1). The right lens fixing part (2229) restricts the right edge (112) of the lens cover (11) from rotating in one direction.

[0270] The right lens support (2228) supports the right edge portion (112) of the lens cover (11), thereby supporting the right lens (122) placed inside the right edge portion (112).

[0271] The right lens fixing member (2229) restricts the rotation of the right edge portion (112) of the lens cover (11) in one direction, thereby restricting the rotation of the right lens (122) positioned inside the right edge portion (112) in one direction.

[0272] In detail, when the smart glass (1) is accommodated in the second groove (2221) of the lower inner case (222), the right lens support (2228) is located below the right edge portion (112) of the lens cover (11) and supports the right edge portion (112) from below.

[0273] In detail, when the smart glass (1) is placed in the second groove (2221) of the lower inner case (222), the magnet member (223) placed in the magnet member receiving portion (2224d) of the lower inner case (222) attracts the central connecting portion (113) of the smart glass (1).

[0274] As a result, the smart glass (1) rotates in one direction (e.g., counterclockwise from the front side to the rear side in FIG. 12). At this time, the right lens fixing part (2229) is located on one side of the lower part of the right edge part (112) of the lens cover (11) to restrict the right edge part (112) from rotating in one direction.

[0275] When the right edge portion (112) of the lens cover (11) rotates in one direction, the lower end of the right edge portion (112) comes into contact with the step surface (22289) formed between the right lens support portion (2228) and the right lens fixing portion (2229). Accordingly, the right edge portion (112) is restricted from rotating in one direction. The smart glass (1) is stably fixed to the second groove (2221) of the lower inner case (222).

[0276] The lower inner case (222) of the present invention is provided with a left lens support (2226) and a right lens support (2228), so that the smart glass (1) does not tilt to one side.

[0277] According to an example of an embodiment of the present invention, the charging case (2) includes a lighting member (227), for example, an LED.

[0278] Referring to FIGS. 6 and 11, the lighting member (227) is positioned on the lower surface of the front edge (222a) of the lower inner case (222). The lighting member (227) is positioned adjacent to the magnet member (223). The lower inner case (222) has a receiving space for accommodating the lighting member (227).

[0279] The lighting element (227) is electrically connected to the battery built into the lower case (22).

[0280] When the smart glass (1) is placed in the lower inner case (222), the lighting member (227) turns on and changes the color of the light depending on the charging status of the smart glass (1).

[0281] Additionally, according to an example of an embodiment of the present invention, the charging case (2) includes a plurality of magnets (M1, M2, M3, M4). FIG. 6 illustrates a plurality of magnets (M1, M2, M3, M4).

[0282] Among the plurality of magnets (M1, M2, M3, M4), the first magnet (M1) and the third magnet (M3) are placed in a receiving space formed in the upper inner case (212). The first magnet (M1) is placed on the left edge of the upper inner case (212), and the third magnet (M3) is placed on the right edge of the upper inner case (212).

[0283] And, among the plurality of magnets (M1, M2, M3, M4), the second magnet (M2) and the fourth magnet (M4) are placed in a receiving space formed in the lower inner case (222). The second magnet (M2) is placed on the left edge (222c) of the lower inner case (222), and the fourth magnet (M4) is placed on the right edge (222d) of the lower inner case (222).

[0284] The first magnet (M1) and the third magnet (M3) exert an attractive force on each other, and the second magnet (M2) and the fourth magnet (M4) exert an attractive force on each other.

[0285] When the charging case (2) is closed, the magnets (M1, M2, M3, M4) prevent the charging case (2) from being easily opened. As a result, the smart glasses (1) can be stably stored in the charging case (2) and charged.
