[0071] Each of the left temple (131) and the right temple (132) includes an inner temple (1311, 1321) and an outer temple (1312, 1322).

[0072] The left temple (131) is formed by combining the inner temple (1311) and the outer temple (1312), and the right temple (132) is also formed by combining the inner temple (1321) and the outer temple (1322). The method of combining the inner temples (1311, 1321) and the outer temples (1312, 1322) follows a well-known method.

[0073] Here, the inner temples (1311, 1321) are positioned on the side facing the user's head. That is, the inner temples (1311, 1321) are positioned facing the user's head. In addition, the outer temples (1312, 1322) face the opposite side of the side facing the inner temples (1311, 1321). In other words, the outer temples (1312, 1322) are positioned on the opposite side of the side facing the user's head.

[0074] The inner temple (1311) of the left temple (131) may be named as the 'left inner temple (1311)', and the outer temple (1312) of the left temple (131) may be named as the 'left outer temple (1312)'. In addition, the inner temple (1321) of the right temple (132) may be named as the 'right inner temple (1321)', and the outer temple (1322) of the right temple (132) may be named as the 'right outer temple (1322)'.

[0075] Each of the left temple (131) and the right temple (132) has a space formed inside by the combination of the inner temple (1311, 1321) and the outer temple (1312, 1322).

[0076] That is, the left temple (131) and the right temple (132) have a preset length in one direction and have space inside.

[0077] The left temple (131) has an anterior side (1313) and a posterior side (1314), and the right temple (132) also has an anterior side (1323) and a posterior side (1324).

[0078] The anterior side (1313, 1323) and the posterior side (1314, 1324) point to opposite sides in the longitudinal direction of the temple.

[0079] The front sides (1313, 1323) of the left temple (131) and the right temple (132) can be connected to the smart glass (1), and the rear sides (1314, 1324) of the left temple (131) and the right temple (132) can be connected to the auxiliary battery assembly (2).

Here, the temple-side edge of the right rim (112) refers to the edge opposite to the edge connected to the central connection (113).

[0082] A space is formed inside the left temple (131) and the right temple (132), and a printed circuit board (PCB), a speaker, a battery, electric wires, and various electrical and electronic components can be placed in the space. Here, the printed circuit board and electric wires may include a flexible printed circuit board (FPCB), depending on an example of the embodiment.

[0083] The front side (1313) of the left temple (131) and the temple-side edge of the left border (111) are rotatably connected. In addition, the front side (1323) of the right temple (132) and the temple-side edge of the right border (112) are also rotatably connected. The above connection method is a conventional method such as a hinge method. A detailed description of the connection method is omitted.

[0084] Each side of the temple (13) forming the posterior side (1314, 1324) of the temple (13) (left temple (131) and right temple (132)) is defined as follows (see Fig. 3).

[0085] In the posterior side (1314) of the left temple (131), the upper surface (1314a) represents the upper side of the left temple (131), the lower surface (1314b) represents the lower side of the left temple (131), the inner surface (1314c) represents the side of the left inner temple (1311) connecting the upper surface (1314a) and the lower surface (1314b), the outer surface (1314d) represents the side of the left outer temple (1312) connecting the upper surface (1314a) and the lower surface (1314b), and the edge side (1314e) represents the side facing the opposite side facing the front side (1313) of the left temple (131). To elaborate, the inner side (1314c) is the side facing the user's head, and the outer side (1314d) is the side facing the opposite side of the side facing the user's head.

[0086] The upper surface (1314a), lower surface (1314b), inner surface (1314c), outer surface (1314d) and edge side surface (1314e) of the rear side (1314) of the left temple (131) described above are surfaces exposed to the outside of the left temple (131).

[0087] And, in the rear side (1324) of the right temple (132), the upper surface (1324a) represents the upper side of the right temple (132), the lower surface (1324b) represents the lower side of the right temple (132), the inner surface (1324c) represents the side of the right inner temple (1321) connecting the upper surface (1324a) and the lower surface (1324b), the outer surface (1324d) represents the side of the right outer temple (1322) connecting the upper surface (1324a) and the lower surface (1324b), and the edge side (1324e) represents the side facing the opposite side facing the front side (1323) of the right temple (132). To elaborate, the inner side (1324c) is the side facing the user's head, and the outer side (1314d) is the side facing the opposite side of the side facing the user's head.

[0088] The upper surface (1324a), lower surface (1324b), inner surface (1324c), outer surface (1324d) and edge side surface (1324e) of the rear side (1324) of the right temple (132) described above are surfaces exposed to the outside of the right temple (132).

[0089] Figure 4 shows the posterior side (1324) of the right temple (132). Figure 4 (a) shows the right outer temple (1322), and Figure 4 (b) shows the right outer temple (1322) removed to show the inside of the right temple (132).

[0090] Figure 5 (a) shows the charging pin (16), printed circuit board (161), and wire (162) shown in Figure 4, and Figure 5 (b) shows the metal member (15) shown in Figure 4.

[0091] The rear side (1324) of the right temple (132) shown in Fig. 4 is also applied to the rear side (1314) of the left temple (131).

[0092] A metal member (15) is placed on the rear side (1314) of the left temple (131) and the rear side (1324) of the right temple (132).

[0093] An internal space is formed inside the rear side (1314) of the left temple (131) and the rear side (1324) of the right temple (132). A metal member (15) is placed in the internal space.

[0094] The metal member (15) may be replaced with a magnetic member. That is, a magnetic member may be placed in the position where the metal member (15) is placed. The magnetic member may be formed in a shape identical to or similar to that of the metal member (15).

[0095] The metal member (15) is formed in a sheet shape. Since the smart glasses (1) are worn on the user's face, they need to be lightweight. By manufacturing the metal member (15) in a thin sheet shape, the weight of the temple (13) is reduced.

[0096] The metal member (15) has the property of being attracted to the magnetic force of a magnet. Accordingly, the rear side (1314, 1324) of the temple (13) (left temple (131) and right temple (132)) can be fixed to the strap connection part (22) by the magnetic force of the strap magnet member (223) (see FIG. 6) arranged in the strap connection part (22) (left strap connection part (221) and right strap connection part (222)) of the auxiliary battery assembly (2).

[0097] The metal member (15) may have a through hole (15h1) for a charging pin.

[0098] The through hole (15h1) for the charging pin is a hole that penetrates the metal member (15).

[0099] A charging pin (16) and a printed circuit board (161) on which the charging pin (16) is mounted are placed in the through hole (15h1) for the charging pin. The printed circuit board (161) includes a flexible printed circuit board (FPCB).

[0100] Since the printed circuit board (161) on which the charging pin (16) is mounted is placed in the charging pin through hole (15h1) of the metal member (15), the printed circuit board (161) and the metal member (15) are not laminated. As a result, the thickness of the temple (13) can be minimized.

[0101] According to an example of an embodiment of the present invention, a through hole (15h1) for a charging pin may not be formed in a metal member (15) on which a charging pin (16) and a printed circuit board (161) on which the charging pin (16) is mounted are not disposed.

[0102] In detail, if the charging pin (16) etc. is arranged on the rear side (1314) of the left temple (131) and not arranged on the rear side (1324) of the right temple (132), a metal member (15) having a through hole (15h1) for the charging pin is arranged on the rear side (1314) of the left temple (131) where the charging pin (16) etc. is arranged, and a metal member without a through hole (15h1) for the charging pin is arranged on the rear side (1324) of the right temple (132) where the charging pin (16) etc. is not arranged.

[0103] By forming a through hole (15h1) for a charging pin in the metal member (15), the arrangement of the charging pin (16) and the printed circuit board (161) on which the charging pin (16) is mounted is made easy, and the thickness and weight of the temple (13) are reduced.

[0104] The through hole (15h1) for the charging pin of the metal member (15) can correspond to the flat shape of the printed circuit board (161) on which the charging pin (16) is mounted.

[0105] In addition, according to an example of an embodiment of the present invention, even if a charging pin (16) or the like is not arranged on the rear side (1314) of the left temple (131) or the rear side (1324) of the right temple (132), a metal member (15) having a through hole (15h1) formed therein may be arranged on the rear side (1314) of the left temple (131) or the rear side (1324) of the right temple (132), or one or more small-sized metal members without a through hole (15h1) formed therein may be arranged. This is to reduce the thickness and weight of the temple (13).

[0106] Additionally, according to an example of an embodiment of the present invention, the metal member (15) may have a through hole (15h2) for a wire.

[0107] The through hole for the wire (15h2) is a hole that penetrates the metal member (15).

[0108] The through hole for the wire (15h2) communicates with the through hole for the charging pin (15h1).

[0109] The through hole for the wire (15h2) communicates with the outside of the metal member (15).

[0110] An electric wire (162) is placed in the through hole (15h2) for the wire.

[0111] The above wire (162) may be named a ‘charging pin wire’.

[0112] The charging pin wire (162) includes a conventional wire, a printed circuit board, and a flexible printed circuit board (FPCB).

[0113] The charging pin wire (162) is connected to the charging pin (16) or the printed circuit board (161) on which the charging pin (16) is mounted.

[0114] By forming a through hole (15h2) for a wire in the metal member (15), the placement of the charging pin wire (162) becomes easier, and the thickness and weight of the temple (13) are reduced.

[0115] The charging pin (16) is formed of an electrical conductor and represents a typical contact terminal through which electricity flows.

[0116] The charging pin (16) is mounted on a printed circuit board (161).

[0117] A plurality of charging pins (16) are arranged, and the plurality of charging pins (16) are arranged in a row.

[0118] One end of the charging pin (16) is exposed to the outside of the temple (13).

[0119] The charging pin (16) is positioned on the rear side (1314) of the left temple (131) or the rear side (1324) of the right temple (132). According to an example of the embodiment of the present invention, the charging pin (16) may be positioned on both the rear side (1314) of the left temple (131) and the rear side (1324) of the right temple (132).

[0120] Electricity supplied from the outside is transmitted to the charging pin (16) and stored in the main body battery (14) that is electrically connected to the printed circuit board (161) on which the charging pin (16) is mounted. Here, the electrical connection is made by the charging pin wire (162) described above.

[0121] The charging pin (16) can receive electricity from the auxiliary battery (25) built into the auxiliary battery assembly (2) by coming into contact with the pogo pin (24) placed in the auxiliary battery assembly (2).

[0122] A plurality of through holes are formed in the rear side (1314, 1324) of the temple (13) (left temple (131) and / or right temple (132)) where the charging pin (16) is arranged. One end of the charging pin (16) passes through the through hole and is exposed to the outside.

[0123] When the charging pin (16) is placed on the rear side (1314) of the left temple (131), a plurality of through holes in which the charging pin (16) is placed are formed on the outer surface (1314d) of the rear side (1314) of the left outer temple (1312).

[0124] And, when the charging pin (16) is placed on the rear side (1324) of the right temple (132), a plurality of through holes in which the charging pin (16) is placed are formed on the outer surface (1324d) of the rear side (1324) of the right outer temple (1322).

[0125] A main body battery (14) is placed in the internal space formed in the rear side (1314, 1324) of the temple (13).

[0126] The main body battery (14) is placed in the left temple (131) and / or the right temple (132).

[0127] The main body battery (14) is a conventional rechargeable battery.

[0128] The shape of the main body battery (14) can correspond to the shape of the internal space of the rear side (1314, 1324) of the temple (13) where the main body battery (14) is placed, and can also be formed in various other shapes.

[0129] The main body battery (14) is fixed to the inner surface of the temple (13) surrounding (forming) the inner space of the rear side (1314, 1324) of the temple (13) by an adhesive tape (171) (which may be referred to as a 'first adhesive tape').

[0130] The first adhesive tape (171) is attached to a portion of one side of the main body battery (14). Specifically, the first adhesive tape (171) is attached along the edge of one side of the main body battery (14).

[0131] For example, the first adhesive tape (171) is a double-sided adhesive tape.

[0132] One side of the first adhesive tape (171) is attached along the edge of one side of the main body battery (14), and the other side (the opposite side of the one side) of the first adhesive tape (171) is attached to the inner surface of the temple (13) (see FIGS. 4 and 8).

[0133] Here, the inner surface of the temple (13) represents the inner side of the left outer temple (1312) and / or the inner side of the right outer temple (1322).

[0134] In detail, the inner side of the left outer temple (1312) represents the opposite side of the outer side (1314d) of the posterior side (1314) of the left outer temple (1312).

[0135] And, the inner side of the right outer temple (1322) represents the opposite side of the outer side (1324d) of the posterior side (1324) of the right outer temple (1322).

[0136] A metal member (15) is placed on one side of the main body battery (14).

[0137] The metal member (15) is placed on the inside of the first adhesive tape (171). That is, the perimeter of the metal member (15) is surrounded by the first adhesive tape (171) (see Fig. 4).

[0138] The metal member (15) is fixed to the inner surface of the temple (13) surrounding (forming) the inner space of the rear side (1314, 1324) of the temple (13) by an adhesive tape (172) (which may be referred to as a 'second adhesive tape').

[0139] The second adhesive tape (172) is attached to the entirety or a portion of one side of the metal member (15).

[0140] For example, the second adhesive tape (172) is a double-sided tape.

[0141] One side of the second adhesive tape (172) is attached to one side of the metal member (15), and the other side (the opposite side of the one side) of the second adhesive tape (172) is attached to the inner side of the temple (13) (see Fig. 8).

[0142] Here, the inner surface of the temple (13) refers to the inner side of the left outer temple (1312) and / or the inner side of the right outer temple (1322). The inner side of the left outer temple (1312) and the inner side of the right outer temple (1322) are as described above.

[0143] A printed circuit board (161) on which a charging pin (16) is mounted is placed in a through hole (15h1) for the charging pin of a metal member (15).

[0144] A printed circuit board (161) on which a charging pin (16) is mounted is fixed to the inner surface of the temple (13) surrounding (forming) the inner space of the rear side (1314, 1324) of the temple (13) by an adhesive tape (173) (which may be referred to as a ‘third adhesive tape’).

[0145] The third adhesive tape (173) is attached to the entirety or a portion of one side of the printed circuit board (161) on which the charging pin (16) is mounted.

[0146] For example, the third adhesive tape (173) is a double-sided tape.

[0147] One side of the third adhesive tape (173) is attached to one side of a printed circuit board (161) on which a charging pin (16) is mounted, and the other side (the opposite side of the one side) of the third adhesive tape (173) is attached to the inner surface of the temple (13) (see Fig. 8).

[0148] Here, the inner surface of the temple (13) refers to the inner side of the left outer temple (1312) and / or the inner side of the right outer temple (1322). The inner side of the left outer temple (1312) and the inner side of the right outer temple (1322) are as described above.

[0149] The first adhesive tape (171) that secures the main body battery (14), the second adhesive tape (172) that secures the metal member (15), and the third adhesive tape (173) that secures the printed circuit board (161) on which the charging pin (16) is mounted are arranged so as not to overlap each other. This is to reduce the thickness of the temple (13).

[0150] By using adhesive tapes (171, 172, 173) to secure the printed circuit board (161) on which the main body battery (14), metal member (15) and charging pin (16) are mounted, the weight and thickness of the temple (13) are reduced.

[0151] When fastening members such as bolts, nuts, and screws are used, the weight and thickness of the temple increase due to the addition of fastening members and components for fixing them.

[0152] <Auxiliary Battery Assembly (2)>

[0153] Fig. 6 illustrates an auxiliary battery assembly (2) of the present invention.

[0154] The auxiliary battery assembly (2) supplies electricity to the smart glass (1).

[0155] Specifically, the auxiliary battery assembly (2) supplies electricity to the main body battery (14) of the smart glass (1) to charge the main body battery (14).

[0156] The auxiliary battery assembly (2) can be connected to the smart glass (1) and can also be separated.

[0157] The auxiliary battery assembly (2) includes a strap portion (21), a strap connection portion (22), and a battery receiving portion (23).

[0158] The strap portion (21) is formed in a long belt shape in one direction (see Fig. 12).

[0159] The strap portion (21) has a preset length in one direction and a preset width in a direction orthogonal to the length direction. The preset length and width are accompanied by a preset thickness. The preset length is formed to be longer than the preset width.

[0160] The strap portion (21) includes one side (211) and a second side (212) opposite to the first side (211). The first side (211) and the second side (212) of the strap portion (21) are sides facing opposite to each other with a thickness interposed therebetween.

[0161] The strap portion (21) has elasticity and elastically supports the back of the head. As a result, the strap portion (21) can be stretched by an external force and returns to its original state when the external force is removed.

[0162] Additionally, the strap portion (21) has flexibility. Due to this, the strap portion (21) is wrapped around the circumference of the head.

[0163] For example, the strap portion (21) may be formed of a material such as silicone or fluoroelastomer.

[0164] Fig. 15 shows an auxiliary battery unit according to examples of an embodiment of the present invention.

[0165] The strap portion (21) illustrated in (a) of Fig. 15 is formed of a material having elasticity and flexibility. When the strap portion (21) has elasticity and flexibility, it is possible to combine multiple battery receiving portions (23) to one strap portion (21), as illustrated in (c) of Fig. 15.

[0166] Additionally, as illustrated in (b) of FIG. 15, the strap portion (21') may be formed into a shape having a specific pattern. This allows the smart glass device to be worn on various head sizes. Here, the specific pattern indicates that the strap portion (21') is formed as a single long string, but has a bend portion in which a certain pattern is repeated.

[0167] Strap connection parts (22) are arranged at both ends (213, 214) of the strap part (21). The both ends (213, 214) of the strap part (21) represent one end (213) in the longitudinal direction of the strap part (21) and the other end (214) opposite to the one end (213).

[0168] An electric wire (242) is arranged inside the strap portion (21) (see Fig. 13). The electric wire (242) may be referred to as a 'pogo pin wire'.

[0169] The pogo pin wire (242) includes not only commonly used wires, but also printed circuit boards and flexible printed circuit boards (FPCB). In other words, the pogo pin wire (242) includes all types of materials through which electricity can flow.

[0170] The pogo pin wire (242) has a preset length in one direction.

[0171] One side of the pogo pin wire (242) is connected to a printed circuit board (241) on which the pogo pin (24) is mounted, and the other side of the pogo pin wire (242) is connected to an auxiliary battery (25).

[0172] Figure 13 shows the process of connecting a pogo pin wire (242) to a strap portion (21).

[0173] As shown in (a) of Fig. 13, the strap portion (21) includes a wire groove portion (215), a cover groove portion (216), and a cover portion (21p).

[0174] The wire groove (215) and the cover groove (216) are formed in a recess shape.

[0175] The wire groove (215) and the cover groove (216) are formed from one end (213) of the strap portion (21) to the middle or adjacent position in the longitudinal direction of the strap portion (21).

[0176] The wire groove (215) and the cover groove (216) are formed by being sunken from one side (211) of the strap part (21) toward the other side (212) in the thickness direction of the strap part (21) to a preset depth.

[0177] Looking at one side (211) of the strap portion (21), the wire groove portion (215) and the cover groove portion (216) are formed to overlap. In detail, the wire groove portion (215) is positioned below the cover groove portion (216) in the thickness direction of the strap portion (21).

[0178] The width of the wire groove (215) is formed narrower than the width of the cover groove (216). Accordingly, a step is formed at the boundary between the wire groove (215) and the cover groove (216).

[0179] The preset length of the wire groove (215) in the longitudinal direction of the strap portion (21) is formed to be longer than the preset length of the cover groove (216). As a result, a passage is formed through which the other side of the pogo pin wire (242) can pass.

[0180] A pogo pin wire (242) is placed in the wire groove (215) (see (b) of Fig. 13). One side and the other side of the pogo pin wire (242) are exposed to the outside of the wire groove (215).

[0181] A cover part (21p) is placed in the cover groove (216) (see (c) of Fig. 13).

[0182] The cover part (21p) is fastened to the cover groove part (216) and covers the pogo pin wire (242).

[0183] The preset length, width, and thickness of the cover portion (21p) correspond to the preset length, width, and depth of the cover groove portion (216).

[0184] The cover part (21p) can be inserted and fixed into the cover groove part (216), for example, by a force-fit method.

[0185] Figure 13 (d) shows that the strap connection part (22) is connected to both ends (213, 214) of the strap part (21) in the state of Figure 13 (c).

[0186] Fig. 13 illustrates a process in which a pogo pin wire (242) is connected to one end (213) of a strap portion (21). This exemplifies the arrangement of a pogo pin (24) in a strap connection portion (22) connected to one end (213) of a strap portion (21).

[0187] According to an example of an embodiment of the present invention, if a pogo pin (24) is placed on a strap connection portion (22) connected to the other end portion (214) of the strap portion (21), a pogo pin wire (242) is connected to the other end portion (214) of the strap portion (21).

[0188] The process of connecting the pogo pin wire (242) to the other end (214) of the strap portion (21) is applied in the same manner as the process illustrated in Fig. 13.

[0189] The strap connection part (22) is placed on the strap part (21).

[0190] The strap connection part (22) can be connected to the temple (13) of the smart glass (1) and can also be separated.

[0191] The auxiliary battery assembly (2) can be connected to the smart glass (1) via a strap connection (22), and can also be separated.

[0192] The strap connecting portion (22) includes an inner plate portion (2221, 2211) that contacts the outer surface (1314d, 1324d) of the rear side (1314, 1324) of the temple (13), and an edge plate portion (2222, 2212) that extends toward the temple (13) along the edge of the inner plate portion (2221, 2211) and wraps around a portion of the upper surface (1314a, 1324a) and the lower surface (1314b, 1314b) of the rear side (1314, 1324) of the temple (13). A detailed description is as follows.

[0193] The strap connection part (22) includes a strap right connection part (222) and a strap left connection part (221).

[0194] Fig. 7 shows the right strap connection part (222) shown in Fig. 6, and Fig. 9 shows the connection between the right strap connection part (222) and the rear side (1324) of the right temple (132).

[0195] The right strap connection part (222) is placed and fixed to one end (213) of the strap part (21). The fixing is done in a known manner.

[0196] The right strap connection part (222) can be connected to the rear side (1324) of the right temple (132) of the smart glass (1), and can also be separated.

[0197] Specifically, the right strap connection portion (222) can be connected to (or in contact with) the posterior side (1324) of the right outer temple (1322), and can also be separated from it.

[0198] The right strap connection portion (222) is formed to wrap around the rear side (1324) of the right outer temple (1322). To this end, the shape of the right strap connection portion (222) is formed to correspond to the shape of the rear side (1324) of the right outer temple (1322).

[0199] The right strap connection part (222) includes a right inner plate part (2221), a right edge plate part (2222), and a right outer plate part (2223).

[0200] The right inner plate (2221) is formed in a plate shape and includes one side and the other side. The one side and the other side are opposite sides. In other words, the one side and the other side are sides facing opposite sides. The one side may be referred to as the "inner side," and the other side may be referred to as the "outer side."

[0201] When the right strap connection part (222) is connected to the rear side (1324) of the right temple (132), the inner surface of the right inner plate part (2221) faces the outer surface (1324d) of the rear side (1324) of the right outer temple (1322) and comes into contact with the outer surface (1324d). In other words, the inner surface of the right inner plate part (2221) faces the user's head. And, the outer surface of the right inner plate part (2221) faces the opposite side of the side facing the user's head.

[0202] A magnetic member (223) (which may be called a ‘strap magnetic member’) is arranged on the inner surface of the right inner plate (2221).

[0203] The strap magnet member (223) represents a magnetic object that attracts metal or other magnetic members. The strap magnet member (223) is arranged on the inner surface of the strap connection portion (22), and one surface of the strap magnet member (223) is exposed to the outside.

[0204] A magnet member receiving groove (2231) (see Fig. 8) for receiving a strap magnet member (223) is formed on the inner surface of the right inner plate (2221).

[0205] The magnet member receiving groove (2231) is a groove shape sunken from the inside to a preset depth, and is formed in a shape corresponding to the shape of the strap magnet member (223).

[0206] The strap magnet member (223) can be inserted and fixed into the magnet member receiving groove (2231), for example, by a force-fit method.

[0207] The strap magnet member (223) is exposed to the outside. In detail, when the right strap connection part (222) is separated from the rear side (1324) of the right temple (132), one side of the strap magnet member (223) is exposed to the outside. As a result, the magnetic force of the strap magnet member (223) strongly acts on the metal member (15) arranged inside the rear side (1324) of the right temple (132). This is because the distance between the strap magnet member (223) and the metal member (15) is closer.

[0208] When the inner surface of the right inner plate (2221) comes into contact with the outer surface (1324d) of the rear side (1324) of the right outer temple (1322), the strap magnet member (223) faces the metal member (15) arranged on the inside of the rear side (1324) of the right temple (132).

[0209] By means of the strap magnet member (223), the strap right connection portion (222) (specifically, the right inner plate portion (2221)) is fixed by contact with the rear side portion (1324) of the right temple (132) (specifically, the right outer temple (1322)). Therefore, even if an external force smaller than the magnetic force of the strap magnet member (223) is applied to the strap right connection portion (222), the strap right connection portion (222) is not separated from the rear side portion (1324) of the right temple (132).

[0210] The right edge plate (2222) is formed at the edge of the right inner plate (2221) and is formed along the edge of the right inner plate (2221).

[0211] The right edge plate (2222) is formed by extending from the edge of the right inner plate (2221) toward the right temple (132) at a preset angle.

[0212] When the right strap connection portion (222) is connected to the rear side (1324) of the right temple (132), the right edge plate portion (2222) wraps around a portion of the upper surface (1324a) and the lower surface (1324b) of the rear side (1324) of the right temple (132).

[0213] The right edge plate (2222) guides the connection between the right strap connection (222) and the right temple (132) and reinforces the connection.

[0214] Specifically, when the right strap connection portion (222) is coupled with the rear side portion (1324) of the right temple (132), the right edge plate portion (2222) comes into contact with the upper surface (1324a) and the lower surface (1324b) of the right temple (132), thus serving to guide the coupling.

[0215] And, when the right side connecting portion (222) of the strap is completely connected to the rear side (1324) of the right temple (132), the right edge plate (2222) is in close contact with the upper surface (1324a) and the lower surface (1324b) of the right temple (132), so that the right side connecting portion (222) of the strap is more strongly connected to the right temple (132). As a result, the right side connecting portion (222) of the strap is not easily separated from the rear side (1324) of the right temple (132).

[0216] The right outer plate (2223) serves as a cover covering the outer surface of the right inner plate (2221).

[0217] The right outer plate (2223) is formed in a plate shape and includes one side and the other side. The one side and the other side are opposite sides. In other words, the one side and the other side are sides facing opposite sides. The one side may be referred to as the "inner side," and the other side may be referred to as the "outer side."

[0218] The inner surface of the right outer plate (2223) faces the outer surface of the right inner plate (2221), and the outer surface of the right outer plate (2223) faces the outer surface of the right strap connection part (222).

[0219] The shape of the inner surface of the right outer plate (2223) is formed to correspond to the shape of the outer surface of the right inner plate (2221). For example, if a protruding shape is formed on the outer surface of the right inner plate (2221), a concave shape that accommodates the protruding shape is formed on the inner surface of the right outer plate (2223).

[0220] The right outer plate (2223) is joined to the right inner plate (2221) by various known methods.

[0221] The left strap connection part (221) is placed and fixed to the other end (214) of the strap part (21) (see Fig. 6). The fixing is done in a known manner.

[0222] The left strap connection part (221) can be connected to the rear side (1314) of the left temple (131) of the smart glass (1), and can also be separated.

[0223] Specifically, the left strap connection portion (221) can be connected (or in contact) with, and also separated from, the posterior side (1314) of the left outer temple (1312).

[0224] The left strap connection portion (221) is formed to wrap around the rear side (1314) of the left outer temple (1312). To this end, the shape of the left strap connection portion (221) is formed to correspond to the shape of the rear side (1314) of the left outer temple (1312).

[0225] The left strap connection part (221) includes a left inner plate part (2211), a left edge plate part (2212), and a left outer plate part (2213).

[0226] The shape of the left strap connection part (221) corresponds to the shape of the right strap connection part (222).

[0227] The left inner plate (2211) is formed in a plate shape and includes one side and the other side. The one side and the other side are opposite sides. In other words, the one side and the other side are sides facing opposite sides. The one side may be referred to as the "inner side," and the other side may be referred to as the "outer side."

[0228] When the left strap connection part (221) is connected to the rear side (1314) of the left temple (131), the inner surface of the left inner plate part (2211) faces the outer surface (1314d) of the rear side (1314) of the left outer temple (1312) and comes into contact with the outer surface (1314d). In other words, the inner surface of the left inner plate part (2211) faces the user's head. And, the outer surface of the left inner plate part (2211) faces the opposite side of the side facing the user's head.

[0229] On the inner surface of the left inner panel (2211), a magnetic member (strap magnetic member) (223) is arranged, similar to the strap right connection part (222).

[0230] A magnet member receiving groove (2231) (see Fig. 8) for receiving a strap magnet member (223) is formed on the inner surface of the left inner plate (2211).

[0231] The magnet member receiving groove (2231) is a groove shape sunken from the inside to a preset depth, and is formed in a shape corresponding to the shape of the strap magnet member (223).

[0232] The strap magnet member (223) can be inserted and fixed into the magnet member receiving groove (2231), for example, by a force-fit method.

[0233] The strap magnet member (223) is exposed to the outside. In detail, when the left strap connection part (221) is separated from the rear side (1314) of the left temple (131), one side of the strap magnet member (223) is exposed to the outside. As a result, the magnetic force of the strap magnet member (223) strongly acts on the metal member (15) arranged inside the rear side (1314) of the left temple (131). This is because the distance between the strap magnet member (223) and the metal member (15) is closer.

[0234] When the inner surface of the left inner plate (2211) comes into contact with the outer surface (1314d) of the rear side (1314) of the left outer temple (1312), the strap magnet member (223) faces the metal member (15) arranged on the inside of the rear side (1314) of the left temple (131).

[0235] By means of the strap magnet member (223), the left strap connection portion (221) (specifically, the left inner plate portion (2211)) is fixed by contact with the rear side portion (1314) of the left temple (131) (specifically, the left outer temple (1312)). Therefore, even if an external force smaller than the magnetic force of the strap magnet member (223) is applied to the left strap connection portion (221), the left strap connection portion (221) is not separated from the rear side portion (1314) of the left temple (131).

[0236] The left edge plate (2212) is formed at the edge of the left inner plate (2211) and is formed along the edge of the left inner plate (2211).

[0237] The left edge plate (2212) is formed by extending from the edge of the left inner plate (2211) toward the left temple (131) at a preset angle.

[0238] When the left strap connection part (221) is connected to the rear side (1314) of the left temple (131), the left edge plate part (2212) wraps around a portion of the upper surface (1314a) and the lower surface (1314b) of the rear side (1314) of the left temple (131).

[0239] The left edge plate (2212) guides the connection between the left strap connection (221) and the left temple (131) and reinforces the connection.

[0240] Specifically, when the left strap connection portion (221) is coupled with the rear side portion (1314) of the left temple (131), the left edge plate portion (2212) comes into contact with the upper surface (1314a) and the lower surface (1314b) of the left temple (131), thus serving to guide the coupling.

[0241] And, when the left strap connection part (221) is completely combined with the rear side (1314) of the left temple (131), the left edge plate part (2212) is in close contact with the upper surface (1314a) and the lower surface (1314b) of the left temple (131), so that the left strap connection part (221) is more strongly combined with the left temple (131). As a result, the left strap connection part (221) is not easily separated from the rear side (1314) of the left temple (131).

[0242] The left outer plate (2213) serves as a cover covering the outer surface of the left inner plate (2211).

[0243] The left outer plate (2213) is formed in a plate shape and includes one side and the other side. The one side and the other side are opposite sides. In other words, the one side and the other side are sides facing opposite sides. The one side may be referred to as the "inner side," and the other side may be referred to as the "outer side."

[0244] The inner surface of the left outer plate (2213) faces the outer surface of the left inner plate (2211), and the outer surface of the left outer plate (2213) faces the outer surface of the left strap connection part (221).

[0245] The shape of the inner surface of the left outer plate (2213) is formed to correspond to the shape of the outer surface of the left inner plate (2211). For example, if a protruding shape is formed on the outer surface of the left inner plate (2211), a concave shape that accommodates the protruding shape is formed on the inner surface of the left outer plate (2213).

[0246] The left outer plate (2213) is joined to the left inner plate (2211) by various known methods.

[0247] Referring to FIGS. 6 and 7, the strap magnet member (223) disposed on the right inner plate (2221) of the right strap connection portion (222) and the left inner plate (2211) of the left strap connection portion (221) is formed in a sheet shape.

[0248] The auxiliary battery assembly (2) is worn on the user's head, so it needs to be lightweight. By manufacturing the strap magnet member (223) in the form of a thin sheet, the weight of the auxiliary battery assembly (2) is reduced.

[0364] The pogo pin (24) is electrically connected to the auxiliary battery (25) placed in the battery receiving portion (23). The electrical connection represents the aforementioned wire.

[0365] In addition, when the strap connection part (22a) is connected to the rear side (1314, 1324) of the temple (13) of the smart glass (1), the pogo pin (24) comes into contact with the charging pin (16) arranged on the edge side (1314e, 1324e) of the rear side (1314, 1324) of the temple (13).

[0366] The electricity charged in the auxiliary battery (25) is transmitted to the main body battery (14) placed in the smart glass (1) through the pogo pin (24) and the charging pin (16).

[0367] A magnetic member (first magnetic member, strap magnetic member) (261) is placed and fixed in the internal space of the strap connection part (22a).

[0368] The first magnetic member (261) represents a magnetic object that attracts iron or other magnetic members.

[0369] The first magnetic member (261) includes not only a general magnet but also a multipole magnet.

[0370] The first magnetic member (261) can be fixed to the inner surface (222a1) of the strap connection portion (22a) by various methods, such as adhesive tape. If adhesive tape is used, the weight of the auxiliary battery assembly (2) is reduced.

[0371] When the strap connecting portion (22a) comes into contact with the rear side (1314, 1324) of the temple (13), the first magnet member (261) faces the main body magnet member (18) arranged in the internal space of the rear side (1314, 1324) of the temple (13) and attracts the main body magnet member (18).

[0372] By means of the main body magnet member (18) and the first magnet member (261), the rear side (1314, 1324) of the temple (13) (specifically, the edge side (1314e, 1324e)) is inserted into and fixed to the temple insertion groove (222a2) formed on one side (222a1) of the strap connection portion (22a). Accordingly, even if an external force smaller than the magnetic force of the first magnet member (261) is applied to the strap connection portion (22a), the strap connection portion (22a) is not separated from the rear side (1314, 1324) of the temple (13).

[0373] A guide protrusion (27) is formed on one side (222a1) of the strap connection portion (22a) (specifically, the temple insertion groove (222a2)).

[0374] The guide protrusion (27) is formed in a position corresponding to the main body fixing part (19) arranged on the temple (13) in the temple insertion groove (222a2). The main body fixing part (19) is arranged on the edge side (1314e, 1324e) of the rear side (1314, 1324) of the temple (13).

[0375] The guide protrusion (27) is inserted into and fixed in the movable cap groove (193) formed on the edge side (1314e, 1324e) of the rear side (1314, 1324) of the temple (13).

[0376] When the strap connecting portion (22a) is connected to the rear side (1314, 1324) of the temple (13), the guide protrusion (27) guides the connection of the strap connecting portion (22a).

[0377] And, after the strap connection part (22a) is combined with the rear side (1314, 1324) of the temple (13), the guide protrusion (27) fixes the strap connection part (22a) to the rear side (1314, 1324) of the temple (13), thereby limiting the strap connection part (22a) from being separated from the rear side (1314, 1324) of the temple (13).

[0378] The guide protrusion (27) includes a guide pillar portion (271, 273), a guide groove portion (273), and a guide catch portion (274).

[0379] The guide pillar portion (271, 272) is formed by protruding from the bottom surface of the temple insertion groove (222a2) toward the rear side (1314, 1324) of the temple (13).

[0380] The guide pillar portions (271, 272) are formed in multiple pieces spaced apart at a preset distance. The space spaced apart at the preset distance forms a guide groove portion (273).

[0381] Each of the plurality of guide pillars (271, 272) is formed into a pillar shape with a preset length.

[0382] A groove is formed between a plurality of guide pillars (271, 272) in the longitudinal direction of the guide pillars (271, 273). The groove may be referred to as a 'guide groove (273)'.

[0383] The guide groove (273) is formed by being sunk to a preset depth from the upper surface (or top) of the guide pillar (271, 272) toward the bottom surface of the temple insertion groove (222a2).

[0384] At one end of a plurality of guide pillars (271, 272), a guide catch (274) is formed that protrudes in a direction perpendicular to the longitudinal direction of the guide pillars (271, 272).

[0385] The guide catch (274) is formed on the upper surface (or top) of the guide pillar (271) and protrudes toward the opposite side of the guide groove (273).

[0386] The guide catch (274) is formed so that the width decreases as it protrudes, and has an inclined side.

[0387] The guide catch (274) acts as a hook.

[0388] The guide catch (274) catches on a catch (not given a symbol) formed inside a moving cap groove (193) formed on the rear side (1314, 1324) of the temple (13).

[0389] The process in which the guide protrusion (27) is inserted into or separated from the moving cap groove (193) of the temple (13) and the guide protrusion (27) is combined with or separated from the moving cap groove (193) is described as follows.

[0390] The guide pillar portions (271, 272) are inserted into the movable cap groove (193) and push the movable cap (191). The upper portions of the guide pillar portions (271, 272) move inward along the interior of the movable cap groove (193) together with the movable cap (191). At this time, the elastic member (192) has a restoring force as its shape is deformed.

[0391] As the guide pillar portions (271, 272) are inserted into the moving cap groove (193), the upper portion of the guide pillar portion (271) on which the guide catch portion (274) is formed is inclined toward the guide groove portion (273), so that the upper portions of the plurality (specifically, two) of guide pillar portions (271, 272) become closer to each other. As a result, the guide pillar portions (271, 272) are easily inserted into the moving cap groove (193).

[0392] When the guide pillar part (271, 272) completes moving in the moving cap groove (193), the guide catch part (274) of the guide pillar part (271) catches on the catch formed in the moving cap groove (193). At this time, the upper part of the guide pillar part (271) returns to its original position.

[0393] The catch formed in the movable cap groove (193) may be a stepped surface formed by widening the diameter of the movable cap groove (193) to a preset depth. The guide catch portion (274) catches on the stepped surface. As a result, the guide protrusion (27) is not easily separated from the movable cap groove (193).

[0394] When an external force is applied to the guide protrusion (27) inserted into the moving cap groove (193) of the temple (13) toward the outside of the moving cap groove (193), the guide engaging portion (274) can easily move along the engaging protrusion due to the inclined surface of the guide engaging portion (274), and the upper portions of the guide pillar portions (271, 272) move outward along the inside of the moving cap groove (193). At this time, the elastic member (192) returns to its original shape, and the moving cap (191) moves to its original position.

[0395] In the process of the guide protrusion (27) being separated from the moving cap groove (193), the guide catch (274) moves along the catch, so that the upper part of the guide pillar part (271) on which the guide catch (274) is formed is tilted again toward the guide groove part (273), and the upper parts of the two guide pillar parts (271, 272) become closer to each other. Then, when the upper parts of the guide pillar parts (271, 272) are separated from the moving cap groove (193), the upper part of the guide pillar part (271) returns to its original position.

[0396] Since the restoring force of the elastic member (192) is applied to the guide protrusion (27), the guide protrusion (27) easily moves outward along the inside of the moving cap groove (193).

[0397] According to another embodiment of the present invention, the guide protrusion (27) may not be formed. The strap connection portion (22a) illustrated in Fig. 18 does not have the guide protrusion (27).

[0398] As illustrated in Fig. 18, in an example embodiment in which a guide protrusion (27) is not formed on one side (222a1) of the strap connecting portion (22a), a magnet member (262) (which may be referred to as a 'second magnet member') is placed and fixed on the inner surface of one side (222a1) of the strap connecting portion (22a).

[0399] Here, the inner surface of one side (222a1) of the strap connecting portion (22a) represents a part of the inner surface surrounding the internal space of the strap connecting portion (22a).

[0400] The second magnet member (262) is placed at a position corresponding to the position where the guide protrusion (27) is formed (see the guide protrusion (27) illustrated in FIG. 17).

[0401] In the example of the embodiment shown in Fig. 18, the moving cap (191) is formed of a material that is well attracted to the magnetic force of the second magnetic member (262).

[0402] For example, the moving cap (191) can be formed of stainless steel that is well attracted to a magnet. Stainless steel has excellent aesthetics in addition to functionality.

[0403] When one side (222a1) of the strap connecting portion (22a) comes into contact with the edge side (1314e, 1324e) of the rear side (1314, 1324) of the temple (13), the second magnet member (262) of the strap connecting portion (22a) attracts the moving cap (191) arranged on the edge side (1314e, 1324e).

[0404] By means of the second magnet member (262) and the moving cap (191), the rear side (1314, 1324) (specifically, the edge side (1314e, 1324e)) of the temple (13) is inserted into and fixed in the temple insertion groove (222a2) of the strap connection part (22a). Accordingly, even if an external force smaller than the magnetic force of the second magnet member (262) is applied to the strap connection part (22a), the strap connection part (22a) is not separated from the rear side (1314, 1324) of the temple (13).

[0405] The second magnetic member (262) illustrated in Fig. 18 can also be applied to the example of the embodiment illustrated in Fig. 17. In this case, the moving cap (191) illustrated in Fig. 17 is formed of a material that is well attracted to the magnetic force of the second magnetic member (262).

[0406] The strap connection part (22a) shown in FIGS. 17 and 18 can also be applied to a charging cable.

[0407] Referring to Fig. 10, an electric wire of a certain length is provided. The electric wire includes one end and the other end pointing in opposite directions.

[0408] A strap connection part (22a) as shown in Fig. 17 or Fig. 18 is arranged at one end of the wire, and a USB port or power cord is arranged at the other end of the wire. The smart glass (1) of the present invention can receive electricity from the outside using the charging cable.
