Description

smart glasses

[0001] The present embodiments relate to smart glasses, and more specifically to smart glasses having low thermal conductivity and enhanced strength.

[0002] Augmented Reality (AR) is a technology that superimposes virtual objects onto the user's view of the real world. Because it combines the real world with a virtual world with additional information in real time, it presents a single image, also known as Mixed Reality (MR). Research and development on hybrid VR systems, which merge real and virtual environments, has been ongoing since the late 1990s, primarily in the United States.

[0003] Augmented reality, a concept that complements the real world with a virtual one, utilizes a virtual environment created with computer graphics, but the real world itself is the primary focus. The computer graphics serve to provide additional information to the real environment. By overlaying a 3D virtual image onto the live image the user is viewing, the distinction between the real world and the virtual screen becomes blurred.

[0004] Augmented reality technology, which blends the real world with virtual objects, allows users to view their surroundings, providing enhanced realism and additional information. For example, when scanning the surroundings with a smartphone camera, information such as the location and phone number of a nearby merchant is displayed in 3D.

[0005] Augmented reality is used in remote medical diagnosis, broadcasting, architectural design, and manufacturing process management. With the recent widespread adoption of smartphones, AR has entered a phase of full-scale commercialization, and various products are being developed in the gaming and mobile solutions industries, as well as in the education sector.

[0006] One way to achieve augmented reality is for users to wear smart glasses. Smart glasses typically contain small electronic components, sensors, displays, and other technological components. While these components require little power, some components can generate heat during operation.

[0007] Therefore, it is necessary to minimize the heat generation problem depending on the design of smart glasses and the efficiency of the devices.

[0008] The present invention is intended to solve the above-described problems, and the technical task of embodiments of the present invention is to provide an inner cover of a temple frame forming smart glasses with a material having low thermal conductivity.

[0009] In addition, the embodiments of the present invention have as their technical task a hook-joining relationship as a joining relationship between an outer cover and an inner cover forming a temple frame.

[0010] The problems to be solved by the present invention are not limited to those described above, and other problems not mentioned will be clearly understood by those skilled in the art to which the present invention pertains from the description below.

[0011] Smart glasses according to embodiments for solving the technical problem described above include a lens frame to which a pair of lenses are coupled and a pair of temple frames hinge-coupled to the lens frame, wherein the temple frames include an outer cover in which electronic components are positioned, an inner cover coupled to the outer cover and including a contact portion that contacts the user's skin, and a metal member at least partially positioned inside the inner cover and overlapping the electronic components, wherein the inner cover may be made of a material having a thermal conductivity lower than a thermal conductivity of the outer cover.

[0012] According to embodiments, the inner cover includes a first surface positioned spaced apart from the electronic component and a second surface on which the contact portion is formed, and the metal member may be positioned between the first surface and the second surface.

[0013] According to embodiments, the metal member may include a central plate positioned inside the inner cover and overlapping the electronic component, and a pair of bending portions formed by bending from the top and bottom of the central plate and exposed to the outside of the inner cover.

[0014] According to embodiments, the bending portion may include at least one insertion hole, and the outer cover may protrude to a certain height and include at least one catch passing through the insertion hole.

[0015] According to embodiments, the bending portion may include a plurality of first bending portions in which the insertion holes are formed and a second bending portion positioned between the plurality of first bending portions, and a slit may be formed between the first bending portion and the second bending portion.

[0016] According to embodiments, the length extending from the central plate of the first bent portion may be longer than the length extending from the central plate of the second bent portion.

[0017] According to embodiments, the central plate may include a through hole formed at a position corresponding to an electronic component having a thickness greater than a certain level among the electronic components.

[0018] According to embodiments, the thermal conductivity of the inner cover may be 0.15 to 0.17 W / mK.

[0019] According to embodiments, the inner cover may be made of liquid silicone rubber (LSR).

[0020] According to embodiments, the metal member may be made of a material having a tensile strength value greater than that of stainless steel and a thermal conductivity less than that of copper.

[0021] According to embodiments, the electronic component includes a printed circuit board (PCB), a speaker, and a battery, and the metal member may be positioned to overlap the printed circuit board.

[0022] According to embodiments, by providing the inner cover of the temple frame forming the smart glasses with a material having low thermal conductivity, heat generated by electronic components inside the temple frame of the smart glasses can be prevented from being transmitted to the user.

[0023] According to embodiments, by providing a hook connection as a connection relationship between an outer cover and an inner cover forming a temple frame, there is an effect of reducing the size of the temple frame or obtaining additional internal space of the temple frame.

[0024] The effects that can be obtained from the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by a person having ordinary skill in the art to which the present invention belongs from the description below.

[0040]

[0041] FIG. 1 is a drawing showing smart glasses according to embodiments. FIG. 2 is a drawing showing the inside of a temple frame of smart glasses according to embodiments.

[0042] The outer cover (210) illustrated in FIG. 2 corresponds to the outer cover (210) illustrated in FIG. 1.

[0043] Referring to FIG. 1, smart glasses (1000) according to embodiments may include a lens frame (100) and a temple frame (200).

[0044] The lens frame (100) can be positioned at a position corresponding to the user's eyes when worn on the user's body. The lens frame (100) can be combined with a pair of lenses, and the lenses can be positioned to cover the user's eyes when worn on the user.

[0045] The temple frame (200) can be hinge-coupled to the lens frame (100). For example, the temple frame (200) can rotate in the direction from the x-axis to the z-axis with respect to the lens frame (100). The temple frames (200) can be formed as a pair.

[0046] The temple frame (200) may include an outer cover (210) and an inner cover (230). As illustrated in FIG. 2, various electronic components (220) may be positioned on the outer cover (210) of the temple frame (200) for driving and operating the smart glasses. At this time, some of the electronic components (220) may generate heat during operation, and the inner cover (230) of the temple frame (200) in the smart glasses (1000) according to the embodiments may prevent the heat generated by the electronic components (220) from moving toward the user.

[0047] Hereinafter, smart glasses (1000) according to embodiments will be described in detail.

[0048] FIG. 3 is an exploded view of the temple frame of smart glasses according to embodiments.

[0049] The temple frame (200) illustrated in Fig. 3 corresponds to the temple frame (200) illustrated in Fig. 1. The outer cover (210) illustrated in Fig. 3 corresponds to the outer cover (210) illustrated in Fig. 2.

[0050] As illustrated in FIG. 3, the temple frame (200) may include an outer cover (210), an inner cover (230), and a metal member (240).

[0051] The outer cover (210) may have electronic components (220) positioned therein as described in FIG. 2. At this time, the electronic components (220) may include a printed circuit board (PCB) (221), a speaker (223), a battery (225), and a flexible printed circuit board (FPCB). The printed circuit board (221) may be a concept that includes not only the printed circuit board but also other hardware for driving the printed circuit board.

[0052] The inner cover (230) may be coupled with the outer cover (210) and may include a contact portion that comes into contact with the user's skin. That is, when the user wears the smart glasses (1000), the inner cover (230) of the temple frame (200) may be positioned at a position that comes into contact with the user's skin, and the outer cover (210) of the temple frame (200) may be positioned at a position that does not come into contact with the user's skin. In addition, the electronic component (220) may be positioned in the accommodation space formed by the outer cover (210) and the inner cover (230).

[0053] At this time, as described in FIG. 2, the electronic component (220) may generate heat during operation, and the inner cover (230) may be made of a material having low thermal conductivity so that the heat generated by the electronic component (220) is not transferred to the user's skin. More specifically, the inner cover (230) may be made of a material having lower thermal conductivity than the outer cover (210). That is, unlike the outer cover (210) that does not come into contact with the user's skin, by forming the material of the inner cover (230) that comes into contact with the user's skin from a material having low thermal conductivity, the smart glasses (1000) according to the embodiments have the effect of preventing heat generated by the electronic component (220) from being transferred to the user.

[0054] For example, the inner cover (230) may be made of liquid silicone rubber (LSR), and the outer cover (210) may be made of TR90 material. That is, the outer cover (210) may be made of a material used in general eyeglass frames, while the inner cover (230) may be made of a liquid silicone rubber material having a lower thermal conductivity than the TR90 material. The thermal conductivity of the inner cover (230) may be 0.15 to 0.17 W / mK, and the thermal conductivity of the outer cover (210) may be 0.22 W / mK, which is greater than the thermal conductivity of the inner cover (230).

[0055] Liquid silicone rubber is a rubber-like material based on a silicone multi-material, and is an environmentally friendly material that does not produce volatile peroxides or residues during the curing process, and can be used as a material for the inner cover (230) that comes into contact with the user's skin.

[0056] In addition, the smart glasses (1000) according to the embodiments may include a metal member (240). When the inner cover (230) is made of liquid silicone rubber, the inner cover (230) may prevent heat generated by the electronic component (220) from being transferred to the user's skin due to its low thermal conductivity, but an external force may be applied to the electronic component (220) present inside. Therefore, the smart glasses (1000) according to the embodiments may include a metal member (240) to prevent an external force from being applied to the electronic component (220).

[0057] In particular, the liquid silicone rubber, which is the material of the inner cover (230), not only has heat resistance that remains stable even at high temperatures, but also has good formability and fluidity, making automated production by injection molding possible. Therefore, the smart glasses (1000) according to the embodiments not only have the advantage of being able to easily manufacture the inner cover (230) using a mold, but also have the advantage of being able to double-inject with a metal member (240) inserted inside the inner cover (230).

[0058] The metal member (240) may be positioned at least partially inside the inner cover (230) and may overlap with the electronic component (220). That is, the metal member (240) may be positioned with at least a portion inserted into the inner cover (230). Therefore, as illustrated in FIG. 1, the metal member (240) is not exposed on the exterior of the smart glasses (1000) according to the embodiments. The inner cover (230) and the metal member (240) will be described in detail with reference to FIG. 4.

[0059] Referring to FIG. 3, the metal member (240) may be positioned at a location where it overlaps with the printed circuit board (221) among various electronic components (220). That is, in order to prevent external force from being applied to the printed circuit board (221) among the electronic components (220) and other hardware components, the metal member (240) may be positioned at a location where it overlaps with the printed circuit board (221) and other hardware components, rather than the entire inner cover (230).

[0060] For example, in the case of a speaker (223), it may be efficient not to place a metal member (240) made of metal from a thermal conductivity perspective. In addition, for example, in the case of a battery (225), it may be efficient not to place a metal member (240) because, unlike a printed circuit board (221) and other hardware components, damage may not occur due to external force.

[0061] The metal member (240) may be made of a material having a tensile strength greater than that of stainless steel and a thermal conductivity less than that of copper. That is, the material of the metal member (240) has a tensile strength greater than that of stainless steel, thereby securing rigidity to protect the electronic component (220) from external force, and at the same time, has a thermal conductivity less than that of copper, thereby minimizing the heat generated by the electronic component (220) toward the user's skin.

[0062] For example, the metal member (240) may be made of a new alloy material, and may be made of YCUT-FX, a titanium copper alloy series. For example, the metal member (240) may have a tensile strength value of 1000 N / mm2, which is greater than that of stainless steel (STS304) with a tensile strength value of 520 N / mm2, and a thermal conductivity value of 50 W / mK, which is less than that of copper with a thermal conductivity of 401 W / mK. However, this is merely an example, and the material of the metal member (240) may not be limited thereto.

[0063] FIG. 4 is a drawing showing an inner cover of smart glasses according to embodiments. More specifically, FIG. 4 (a) is a drawing showing an inner cover with a metal member inserted, and FIG. 4 (b) is a drawing showing a cross-section of the inner cover with the metal member inserted.

[0064] The inner cover (230) illustrated in Fig. 4 corresponds to the inner cover (230) illustrated in Figs. 1 and 3. The metal member (240) illustrated in Fig. 4 corresponds to the metal member (240) illustrated in Fig. 3.

[0065] As illustrated in (a) and (b) of FIG. 4, at least a portion of the metal member (240) may be inserted into the inner cover (230). More specifically, as will be described later in FIG. 5, the central plate (241, see (a) of FIG. 5) of the metal member (240) may be positioned inside the inner cover (230), and the bent portion (243, see (a) of FIG. 5) of the metal member (240) may be positioned outside the inner cover (230).

[0066] The inner cover (230) may be formed of a first surface (231) and a second surface (233) by a metal member (240). Referring to (b) of FIG. 4, the first surface (331) may be positioned in the -x-axis direction with respect to the metal member (240), and the second surface (333) may be positioned in the x-axis direction with respect to the metal member (240). That is, the first surface (331) corresponds to a portion that is not visible from the outside when the outer cover (210) and the inner cover (230) are combined, and is located at a certain distance from the electronic component (220), and the second surface (333) corresponds to a portion that is formed at a contact portion that comes into contact with the user's skin and is visible from the outside when the outer cover (210) and the inner cover (230) are combined.

[0067] That is, as described above, the inner cover (230) may be made of a material with low thermal conductivity, for example, liquid silicone rubber, to prevent heat generated by the electronic component (220) from being transferred to the user's skin, and at the same time, a metal member (240) may be inserted into the inner cover (230) to prevent external force acting on the electronic component (220), particularly to prevent external force acting on the printed circuit board (221) and other hardware among the electronic component (220) that are vulnerable to external force.

[0068] Accordingly, the heat generated by the electronic component (220) first reaches the first surface (231), but a relatively small amount reaches the metal member (240) due to the low thermal conductivity of the first surface (231). In addition, the metal member (240) also has a higher thermal conductivity than the inner cover (230), but a lower thermal conductivity than copper, and at the same time, in order to be transferred to the user side after passing through the metal member (240), it must pass through the second surface (233) with low thermal conductivity. Consequently, the smart glasses (1000) according to the embodiments can prevent the heat generated by the electronic component (220) from being transferred to the user side.

[0069] FIG. 5 is a drawing illustrating a metal member and an outer cover of smart glasses according to embodiments. More specifically, FIG. 5 (a) is a drawing illustrating the metal member, and FIG. 5 (b) is a drawing illustrating the outer cover. FIG. 6 is a drawing illustrating a state in which a metal member is coupled to the outer cover of smart glasses according to embodiments.

[0070] The outer cover (210) illustrated in FIG. 5 corresponds to the outer cover (210) illustrated in FIGS. 1 to 3. More specifically, the outer cover (210) illustrated in FIG. 5 represents an outer cover (210) that is an enlarged portion of part A of the outer cover (210) illustrated in FIG. 3. The metal member (240) illustrated in FIG. 5 corresponds to the metal member (240) illustrated in FIGS. 3 and 4. The outer cover (210) illustrated in FIG. 6 corresponds to the outer cover (210) illustrated in FIGS. 1, 2, 3, and 5. The metal member (240) illustrated in FIG. 6 corresponds to the metal member (240) illustrated in FIGS. 3 to 5.

[0071] As shown in (a) of FIG. 5, the metal member (240) may include a central plate (241) and a bending portion (243).

[0072] The central plate (241) is positioned inside the inner cover (230) and can be arranged to overlap with the electronic components (220). That is, the central plate (241) can be positioned to overlap with the printed circuit board (221) and other hardware in order to protect the printed circuit board (221) and other hardware among the electronic components (220) that are vulnerable to external force. In addition, as described in FIG. 4, the central plate (241) can be inserted into the inner cover (230). More specifically, the inner cover (230) can include a first surface (231) positioned in the direction in which the electronic components (220) are positioned (-x-axis direction, see FIG. 4) and a second surface (233) positioned in the direction in which the user is positioned (x-axis direction, see FIG. 4) based on the central plate (241).

[0073] In addition, the central plate (241) may include a through hole (247) formed at a position corresponding to an electronic component (220) having a certain thickness or more among the electronic components (220). In other words, since a component having a thick thickness among various electronic components (220) may come into contact with the metal member (240), the through hole (247) may be formed at a position corresponding to the position of the component having a thick thickness to prevent this. There may be at least one through hole (247).

[0074] The folded portion (243) is formed by being folded in a predetermined direction from the top or bottom of the central plate (241), and unlike the central plate (241) located inside the inner cover (230), it may be located on the outside of the inner cover (230). In this case, the predetermined direction is the direction toward the outer cover (210) (-x-axis direction). Therefore, as illustrated in FIG. 1, the folded portion (243) is not exposed on the exterior of the smart glasses (1000) according to the embodiments. It is preferable that the folded portions (243) be a pair.

[0075] At least one insertion hole (245) may be formed in the bending portion (243). More specifically, at least one insertion hole (245) may be formed in the first bending portion (243a) among the bending portions (243). As will be described later, a catch portion (215) formed in the outer cover (210) is caught in the insertion hole (245), thereby allowing the metal member (240) to be coupled with the outer cover (210). In addition, as a result, the inner cover (230) with the metal member (240) inserted therein may be coupled with the outer cover (210).

[0076] The bending portion (243) may include at least one first bending portion (243a) and at least one second bending portion (243b). A slit (244) may be formed between the first bending portion (243a) and the second bending portion (243b). That is, the first bending portion (243a) and the second bending portion (243b) may be formed to be spaced apart from each other by a certain distance.

[0077] As described above, the first bent portion (243a) of the metal member (240) allows the metal member (240) to be coupled with the outer cover (210) by forming an insertion hole (245), and the second bent portion (243b) of the metal member (240) can reinforce the rigidity provided by the metal member (240). Accordingly, the length of the second bent portion (243b) formed parallel to the central plate (241) or the area occupied by the second bent portion (243b) can be adjusted depending on the rigidity of the metal member (240).

[0078] Additionally, the length extended from the central plate (241) of the second bending portion (243b) may be smaller than the length extended from the central plate (241) of the first bending portion (243a). The length extended from the central plate (241) of the second bending portion (243b) may be determined according to the thickness of the electronic component (220). In other words, the length extended from the central plate (241) of the second bending portion (243b) may be adjusted so as not to come into contact with the electronic component (220).

[0079] Referring to (b) of FIG. 5, the outer cover (210) may include a hook (215) protruding to a certain height, and the hook (215) may be hooked to an insertion hole (245) formed in the metal member (240) as described above, thereby fixing the metal member (240) to the outer cover (210). In other words, movement of the metal member (240) toward the outer cover (210) (movement in the -x-axis direction) may be prevented.

[0080] More specifically, the outer cover (210) may include a central cover (211) that is parallel to the central plate (241) of the metal member (240) and upper and lower covers (213) that are bent and extended in a certain direction from the upper and lower ends of the central cover (211), i.e., are parallel to the bent portion (243) of the metal member (240). Accordingly, a catch portion (215) that protrudes to a certain height may be formed on the upper and lower covers (213), and more specifically, the catch portion (215) may be formed at a position that can pass through the insertion hole (245).

[0081] Referring to FIG. 6 together, FIG. 6 shows a state in which a metal member (240) is coupled to an outer cover (210) by the hooking portion (215) being hooked to an insertion hole (245). The hooking portion (215) has a shape that protrudes to a certain height, and as the hooking portion (215) passes through the insertion hole (245), the metal member (240) can be coupled to the outer cover (210). More specifically, as described in FIG. 4, at least a portion (e.g., the central plate (241)) of the metal member (240) is inserted into the inner cover (230), and as a result, the metal member (240) is coupled to the outer cover (210), so that the inner cover (230) can also be coupled to the outer cover (210).

[0082] At this time, it is desirable that the number of catches (215) and insertion holes (245) be the same. Fig. 5 illustrates a case in which there are a total of six catches (215) and insertion holes (245), three each at the top and bottom, but this is merely an example and there is no limitation on the number.

[0083] FIG. 7 is a cross-sectional view showing a state in which a metal member and an inner cover are coupled to an outer cover of smart glasses according to embodiments. More specifically, (a) of FIG. 7 is a cross-sectional view along the xy plane (see FIG. 1) of a state in which an inner cover is coupled to an outer cover of conventional smart glasses, and (b) of FIG. 7 is a cross-sectional view along the xy plane (see FIG. 1) of a state in which an inner cover is coupled to an outer cover of smart glasses according to embodiments.

[0084] The outer cover (210) illustrated in Fig. 7 corresponds to the outer covers (210) illustrated in Figs. 1, 2, 3, 5, and 6. The printed circuit board (221) illustrated in Fig. 7 corresponds to the printed circuit board (221) illustrated in Fig. 2. The inner cover (230) illustrated in Fig. 7 corresponds to the inner covers (230) illustrated in Figs. 1, 3, 4, and 5. The metal member (240) illustrated in Fig. 7 corresponds to the metal members (240) illustrated in Figs. 3 to 6.

[0085] As illustrated in (a) of Fig. 7, in the conventional smart glasses, a bond was applied to the location where the outer cover (10) and the inner cover (30) meet in order to combine the inner cover (30) with the outer cover (10). That is, the conventional outer cover (10) and the inner cover (30) were combined with each other by bonding, and due to the nature of the bonding, a bonding section of at least 0.8 mm was required for a more secure combination. In addition, a gap of at least 0.2 mm from the outer cover (10) was required for the operation of the printed circuit board (20), and as a result, the conventional smart glasses required a gap of at least 1.0 mm from the outer cover (10) to the printed circuit board (20).

[0086] Referring to (b) of FIG. 7, the outer cover (210) and the inner cover (230) of the smart glasses (1000) according to the embodiments can be coupled to each other by a hook connection. More specifically, as described in FIGS. 6 and 7, the hooking portion (215) formed on the outer cover (210) passes through the insertion hole (245) formed on the metal member (240), thereby allowing the metal member (240) to be coupled to the outer cover (210) and the inner cover (230) into which the metal member (240) is inserted. At this time, the hooking portion (215) is formed to protrude at a certain height, and the certain height can be 0.4 mm. That is, while the conventional bonding requires a bond-applying section of 0.8 mm, the hook-joining of the smart glasses (1000) according to the embodiments can be caught in the insertion hole (245) even if the catch (215) is formed to a height of 0.4 mm. Therefore, unlike the conventional smart glasses that require a gap of at least 1.0 mm from the outer cover (10) to the printed circuit board (20), the smart glasses (1000) according to the embodiments only require a gap of 0.6 mm from the outer cover (210) to the printed circuit board (221), thereby providing an effect of providing a free space of about 0.4 mm.

[0087] For example, the smart glasses (1000) according to the embodiments may reduce the height (length in the y-axis direction, see FIG. 1) of the temple frame (200) by reducing the free space of 0.4 mm. Alternatively, for example, the smart glasses (1000) according to the embodiments may use a larger printed circuit board (221) or add other components to the free space of 0.4 mm while maintaining the height of the temple frame (200).

[0088] FIG. 8 is a cross-sectional view of a temple frame of smart glasses according to embodiments. More specifically, FIG. 8 is a cross-sectional view of the temple frame (200) of the smart glasses (1000) illustrated in FIG. 1 along the xy plane.

[0089] The outer cover (210) illustrated in Fig. 8 corresponds to the outer covers (210) illustrated in Figs. 1, 2, 3, 5, 6, and 7. The printed circuit board (221) illustrated in Fig. 8 corresponds to the printed circuit boards (221) illustrated in Figs. 3 and 7. The inner cover (230) illustrated in Fig. 8 corresponds to the inner covers (230) illustrated in Figs. 1, 3, 4, and 7. The metal member (240) illustrated in Fig. 8 corresponds to the metal members (240) illustrated in Figs. 3 to 7.

[0090] Referring to FIG. 8, the outer cover (210) can be hook-coupled with the metal member (240), and as a result, the inner cover (230) with the metal member (240) inserted therein can be coupled with the outer cover (210). In addition, the metal member (240) can be positioned to overlap with the printed circuit board (221) in order to protect the printed circuit board (221) among the electronic components (220) from external force.

[0091] In particular, heat generated from the printed circuit board (221) can largely move in the x-axis direction and the -x-axis direction, and while heat movement in the -x-axis direction is not related to the user, heat movement in the x-axis direction can be transferred to the user's skin side. Therefore, as described in FIGS. 1 to 7, the inner cover (230) is made of a material having low thermal conductivity, and thus, heat generated by various electronic components (220), including the printed circuit board (221), can be prevented from moving to the user's skin side.

[0092] In addition, the metal member (240) protects the printed circuit board (221) and other hardware among the electronic components (220) that are vulnerable to external force from external force, and at the same time, the inner cover (230) having low thermal conductivity surrounds it, so that even when the metal member (240) is inserted, the heat generated by the printed circuit board (221) and other hardware can be prevented from moving toward the user's skin. In other words, referring to FIG. 4, the heat generated from the printed circuit board (221) first meets the first surface (231) of the inner cover (230), and the movement of the heat in the x-axis direction can be partially prevented by the low thermal conductivity of the first surface (231). In addition, during the movement in the x-axis direction, the metal member (240) having relatively higher thermal conductivity than the inner cover (230) meets, but then meets the second surface (233) of the inner cover (230) again. Accordingly, the smart glasses (1000) according to the embodiments have the effect of preventing heat generated from being transferred to the user's skin.
