Description

smart glasses

[0001] The present embodiments relate to smart glasses, and more specifically, to smart glasses that reduce the coupling deviation when combining a lens and a frame.

[0002] Augmented Reality (AR) is a technology that overlays virtual objects onto the real world seen by the user. It is also called Mixed Reality (MR) because it combines a virtual world with real-time additional information to display a single image. As a hybrid VR system that fuses real and virtual environments, research and development has been underway since the late 1990s, primarily in the United States.

[0003] Augmented reality, a concept that complements the real world with a virtual world, uses a virtual environment created with computer graphics, but the real environment is the main focus. Computer graphics play the role of providing additional information necessary for the real environment. This means that by overlapping a 3D virtual image onto the real-world image the user is viewing, the distinction between the real environment and the virtual screen becomes blurred.

[0004] Augmented reality technology, which combines the real environment with virtual objects, allows users to view the actual surroundings, providing a greater sense of realism and additional information. For example, when a smartphone camera is pointed at the surroundings, information such as the location of nearby animals and phone numbers is displayed as a 3D image.

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

[0006] One way to realize augmented reality is for users to wear smart glasses. Smart glasses are wearable devices designed to allow the wearer to view the external environment and interact with digital information, and the optical module, which is one of the core components of smart glasses, plays a role related to the display of visual information.

[0007] For the optical module to function properly, it must be integrated into the smart glasses frame without deviation, and it is necessary to increase the efficiency of this manufacturing process.

[0008] The present invention aims to solve the aforementioned problems, and the embodiments of the present invention have as their technical objective the provision of smart glasses capable of guiding the combination of a lens and a lens frame.

[0012] According to embodiments, the first guide portion may include a first bracket formed by protruding from the outer surface of the lens; and a first guide hole formed by being drawn in toward the lower direction on the upper surface of the first bracket.

[0013] According to embodiments, the rear frame includes a first projection formed to protrude toward the front direction at a position corresponding to the first guide hole, and the first projection can penetrate the first guide hole when the lens and the rear frame are coupled.

[0014] According to embodiments, the second guide portion may include a second bracket formed by protruding from the outer surface of the lens; and a second guide hole formed by being drawn into the side of the second bracket toward the lens side.

[0015] According to embodiments, the rear frame includes a second projection formed to protrude toward the front direction at a position corresponding to the second guide hole, and the second projection can penetrate the second guide hole when the lens and the rear frame are coupled.

[0016] According to embodiments, the third guide portion may include a plate-shaped protrusion formed by protruding from the outer surface of the lens.

[0017] According to embodiments, the rear frame includes a coupling groove formed by being inserted at a position corresponding to the protruding plate, and the protruding plate can be inserted into the coupling groove when the lens and the rear frame are coupled.

[0018] According to the embodiments, the width of the coupling groove may be formed to be larger than the width of the protruding plate.

[0019] According to embodiments, the lens includes a connecting portion formed by protruding from the outer surface of the lens, and the pair of lenses can be joined together by the connecting portion.

[0037] FIG. 1 is a drawing showing smart glasses (1000) according to embodiments. FIG. 2 is a disassembled drawing of a lens frame (100) to which a lens (300) of smart glasses (1000) according to embodiments is attached. FIG. 3 is a top view of a lens frame (100) to which a lens (300) of smart glasses (1000) according to embodiments is attached.

[0038] Hereinafter, in describing the smart glasses (1000) according to the embodiments, the left and right directions are described based on the x-axis direction, the up and down directions are described based on the y-axis direction, and the directions facing the front and back are described based on the z-axis direction.

[0039] Referring to FIGS. 1 and FIGS. 2, smart glasses (1000) according to embodiments may include a lens frame (100) and a temple frame (200).

[0040] Smart glasses (1000) are glasses that incorporate digital technology and may correspond to a wearable device designed to allow a user to check and interact with various information in real time. Smart glasses (1000) can provide the user with an experience that combines reality and digital information through Augmented Reality (AR) technology. For example, smart glasses (1000) can project a digital screen (such as a hologram or graphic) onto a lens (300) attached to a lens frame (100) to overlay virtual information onto the real world. Alternatively, for example, smart glasses (1000) can provide information by having a mounted camera (301) or sensor scan the user's surrounding environment to create a 3D model or recognize specific objects.

[0041] The lens frame (100) can be positioned at a location corresponding to the user's eyes while worn on the user's body. The lens frame (100) can be combined with a pair of lenses (300), and the lenses (300) can be positioned to cover the user's eyes while worn on the user. More specifically, the lenses (300) can be a type of optical module configured to display an image and to display the image in such a way that when the user wears the smart glasses (1000), the image of both eyes is combined and perceived.

[0042] The temple frame (200) can be hinge-connected to the lens frame (100). The temple frame (200) can rotate relative to the lens frame (100). For example, the temple frame (200) can rotate clockwise or counterclockwise relative to the y-axis. The temple frame (200) can be made up of a pair.

[0043] Electronic components may be placed inside the temple frame (200) to realize augmented reality provided by the smart glasses (1000). For example, sensors, speaker modules, a printed circuit board (PCB), a battery, etc., may be placed in the internal space. The printed circuit board may be a concept that includes not only the printed circuit board but also other hardware for driving the printed circuit board.

[0044] The sensor may correspond to a touch sensor that senses a user's touch, a sensing sensor that detects the user's wearing, or both a touch sensor and a sensing sensor. The touch sensor may be attached and positioned on the outer side of the interior of the temple frame (200), and the sensing sensor may be attached and positioned on the inner side of the interior of the temple frame (200). That is, the touch sensor may be positioned furthest from the user's face, and the sensing sensor may be positioned closest to the user's face.

[0045] The speaker module is a module that outputs sound and can be placed near the user's ear. That is, the speaker module can be attached and placed on the inner side of the temple frame (200) to provide sound to the user, and can be placed particularly close to the user's ear.

[0046] The battery can be placed at the rearmost side of the interior of the temple frame (200). That is, the battery can be placed at the location furthest from the lens frame (100), and, for example, the battery can be placed behind the user's ear when worn.

[0047] The lens frame (100) can be positioned at a location corresponding to the user's eyes while worn on the user's body. The lens frame (100) can be combined with a pair of lenses (300), and the lenses (300) can be positioned to cover the user's eyes while worn on the user. More specifically, the lenses (300) can be a type of optical module configured to display an image and to display the image in such a way that when the user wears the smart glasses (1000), the image of both eyes is combined and perceived.

[0048] A lens frame (100) may be equipped with a camera (102) mounted inside, and the camera lens (101) of the mounted camera (102) may be exposed to the outside of the lens frame (100). That is, the camera (102) mounted inside the smart glasses (1000) may provide an image through the camera lens (101) exposed to the outside of the lens frame (100). As shown in FIGS. 1 and 2, only one camera lens (101) may be formed, or, unlike as shown in FIGS. 1 and 2, two may be formed. If two camera lenses (101) are formed, they may be placed on each side of a pair of lenses.

[0049] The lens frame (100) may include a rear frame (110) that exposes the rear of a pair of lenses (300) and a front frame (120) that is combined with the rear frame (110) and exposes the front of a pair of lenses (300). That is, the rear frame (110) and the front frame (120) are combined with each other, and the lens (300) is combined between the rear frame (110) and the front frame (120), so that the lens (300) can be combined to the lens frame (100).

[0050] The rear frame (110) and the front frame (120) may each include an exposure groove (10, 20) to expose the lens (300). More specifically, the rear frame (110) may include a rear exposure groove (10) to expose the rear of the lens (300), and the front frame (120) may include a front exposure groove (20) to expose the front of the lens (300).

[0051] The rear frame (110) may include a metal dummy formed in the rear exposure groove (10) for mold fitting during injection. That is, when the rear frame (110) is injected, the metal dummy is included inside the rear exposure groove (10), and the rear frame (110) during injection may not expose the rear surface of the lens (300). The metal dummy refers to a residue of metal material or an unnecessary protrusion that occurs mainly during the mold manufacturing or maintenance process, or may occur during injection molding. The formed metal dummy can be removed later by CNC machining. CNC (Computer Numerical Control) is a technology that produces parts with complex shapes by precisely controlling a machine through a computer program, and CNC machining is a precision machining technology controlled by a computer, which refers to a manufacturing process that processes various materials such as metal, plastic, and wood into a desired shape.

[0052] A lens (300) coupled to a rear frame (110) and a front frame (120) can be connected to a Flexible Printed Circuit Board (FPCB) (103). For example, the lens (300) can be connected to an FPCB (103) placed at the top. The FPCB (103) can be electrically connected at both ends to electronic components, etc., placed inside the temple frame (200), thereby allowing the lens (300) to display an image.

[0053] Referring to FIG. 3, a lens (300) can be coupled between a rear frame (110) and a front frame (120) as described above. More specifically, the rear frame (110) can be coupled to a part of the rear and a part of the side of the lens (300), and the front frame (120) can be coupled to a part of the front and the rest of the side of the lens (300).

[0054] The rear frame (110) may include a metal member (130) made of a lightweight material formed in the area where it meets the lens (300). More specifically, the metal member (130) may be included in the interior of the rear frame (110) by an insert method. For example, the metal member (130) may be made of aluminum, but is not limited thereto. More specifically, the rear frame (110) may include a metal member (130) formed in the rear and a portion of the side where it meets the lens (300). As shown in FIG. 3, the metal member (130) may be formed in only one of the areas of the rear frame (110) where it meets the lens (300), but it may also be formed in both areas.

[0055] The smart glasses (1000) according to the embodiments have the effect of securing the strength of the lens frame (100) and simultaneously providing a lightweight effect by using a rear frame (110) that includes a metal member (130) made of a lightweight material inside.

[0056] FIG. 4 is a drawing showing the rear frame (110) of smart glasses (1000) according to embodiments. FIG. 5 is a drawing showing the lens (300) of smart glasses (1000) according to embodiments.

[0057] First, referring to FIG. 5, a lens (300) coupled to a rear frame (110) of smart glasses (1000) according to embodiments may include a guide portion (310, 320, 330) that guides coupling with the rear frame (110). The guide portion (310, 320, 330) may include a first guide portion (310), a second guide portion (320), and a third guide portion (330).

[0058] The first guide member (310) is configured to prevent movement of the lens (300) in the left and right directions. By the first guide member (310), the lens (300) can be connected to the rear frame (110) by guiding the left and right directions at the correct connection position with the rear frame (110). That is, the first guide member (310) can guide the lens (300) so that the x-axis coordinate representing the left and right directions corresponds to the correct x-axis coordinate among the coordinates representing the correct connection position.

[0059] The first guide part (310) may include a first bracket (311), a first guide hole (312), and a first fixing hole (313).

[0060] The first bracket (311) may be formed protruding from the outer surface of the lens (300). For example, as shown in FIG. 5, the first bracket (311) may be formed protruding upward from the upper surface of the lens (300). Alternatively, the first bracket (311) may be formed on an upper cover (301) formed on the upper surface of the lens (300), or may be formed integrally with the upper cover (301). Referring to FIG. 5, the first bracket (311) may be formed in a plate shape having thickness, and the thickness of the first bracket (311) may be formed thinner than the thickness of the lens (300).

[0061] The first guide hole (312) can be formed by being inserted downwardly into the upper surface of the first bracket (311). That is, the first guide hole (312) is formed on the upper surface of the first bracket (311) and can be formed in the shape of a groove with an open upper surface.

[0062] Referring to FIG. 4, the rear frame (110) may include a first projection (111) formed to protrude toward the front direction at a position corresponding to where the first guide hole (312) is formed. By the first projection (111) penetrating the first guide hole (312), the lens (300) can be coupled with the rear frame (110). At this time, the position corresponding to where the first guide hole (312) is formed may represent the exact coupling position where the lens (300) is coupled with the rear frame (110). The coupling process will be explained in detail in FIG. 6.

[0063] The first fixing hole (313) is a hole formed on the first bracket (311) and can be formed in a shape that penetrates in the thickness direction of the first bracket (311). Referring together to FIG. 4, the rear frame (110) may include a first fixing groove (114) formed by being concavely recessed toward the rear direction at a position corresponding to where the first fixing hole (313) is formed. By fixing the first fixing groove (114) and the first fixing hole (313) using a screw member or the like, the lens (300) and the rear frame (110) can be fixed.

[0064] The second guide part (320) is configured to prevent movement of the lens (300) in the vertical direction, and the lens (300) can be coupled to the rear frame (110) by being guided in the vertical direction by the second guide part (320) at the correct coupling position with the rear frame (110). That is, the second guide part (310) can guide the y-axis coordinate representing the left and right direction among the positions of the lens (300) so that it corresponds to the correct y-axis coordinate among the coordinates representing the correct coupling position.

[0065] The second guide part (320) may include a second bracket (321), a second guide hole (322), and a second fixing hole (323).

[0066] The second bracket (321) may be formed protruding from the outer surface of the lens (300). For example, as shown in FIG. 5, the second bracket (321) may be formed protruding in a rightward direction from the upper surface of the lens (300). Alternatively, the second bracket (321) may be formed on the upper cover (301) formed on the upper surface of the lens (300), or may be formed integrally with the upper cover (301). Referring to FIG. 5, the second bracket (321) may be formed in a plate shape having thickness, and the thickness of the second bracket (321) may be formed thinner than the thickness of the lens (300).

[0067] The second guide hole (322) can be formed by being inserted into the side of the second bracket (321) toward the direction of the lens (300). That is, the second guide hole (322) can be formed on the side of the second bracket (321) and can be formed in the shape of a groove with a hole in the side. For example, as shown in FIG. 5, when the second bracket (321) is formed protruding toward the right, the second guide hole (322) can be formed by being inserted into the side of the second bracket (321) toward the right.

[0068] Referring to FIG. 4, the rear frame (110) may include a second projection (112) formed to protrude toward the front direction at a position corresponding to where the second guide hole (322) is formed. By the second projection (112) penetrating the second guide hole (322), the lens (300) can be coupled with the rear frame (110). At this time, the position corresponding to where the second guide hole (322) is formed may represent the exact coupling position where the lens (300) is coupled with the rear frame (110). The coupling process will be explained in detail in FIG. 6.

[0069] The second fixing hole (323) is a hole formed on the second bracket (321) and can be formed in a shape that penetrates in the thickness direction of the second bracket (321). Referring together to FIG. 4, the rear frame (110) may include a second fixing groove (115) formed by being concavely recessed toward the rear direction at a position corresponding to where the second fixing hole (323) is formed. By fixing the second fixing groove (115) and the second fixing hole (323) using a screw member or the like, the lens (300) and the rear frame (110) can be fixed.

[0070] The third guide member (330) is configured to prevent movement of the lens (300) in the forward and backward directions. By the third guide member (330), the lens (300) can be coupled to the rear frame (110) by guiding the forward and backward directions at the correct coupling position with the rear frame (110). That is, the third guide member (330) can guide the lens (300) so that the z-axis coordinate representing the forward and backward direction corresponds to the correct z-axis coordinate among the coordinates representing the correct coupling position.

[0071] The third guide portion (330) may include a plate-shaped protruding plate (331). That is, the third guide portion (330) may refer to the protruding plate (331).

[0072] The protruding plate (331) may be formed by protruding from the outer surface of the lens (300). For example, as shown in FIG. 5, the protruding plate (331) may be formed by protruding downward from the lower surface of the lens (300). Referring to FIG. 5, the protruding plate (331) may be formed in a plate shape having height.

[0073] Referring to FIG. 4, the rear frame (110) may include a coupling groove (113) formed by being inserted at a position corresponding to where the protruding plate (331) is formed. By inserting the protruding plate (331) into the coupling groove (113), the lens (300) can be coupled with the rear frame (110). At this time, the position corresponding to where the protruding plate (331) is formed may represent the exact coupling position where the lens (300) is coupled with the rear frame (110). The coupling process will be explained in detail in FIG. 6.

[0074] FIG. 6 is a drawing showing the state in which a lens (300) is attached to a rear frame (110) in smart glasses (1000) according to embodiments.

[0075] Figure 6 explains in detail the process of attaching the lens (300) to the rear frame (110).

[0076] Referring to FIG. 6, the lens (300) can be coupled to the rear frame (110), and more specifically, the lens (300) can be coupled to the rear frame (110) by guiding the position to an accurate coupling position by the first guide part (310), the second guide part (320), and the third guide part (330).

[0077] First, the position of the lens (300) can be adjusted by the third guide part (330) so that the z-axis coordinate representing the front-rear direction corresponds to the correct z-axis coordinate among the coordinates representing the correct coupling position. That is, referring to FIGS. 4 and FIGS. 5 together, the position of the lens (300) in the front-rear direction can be adjusted by inserting the protruding plate (331) of the third guide part (330) into the coupling groove (113) of the rear frame (110).

[0078] More specifically, the lens (300) can be primarily coupled to the rear frame (110) by inserting the protruding plate (331) into the coupling groove (113) as it moves downward.

[0079] With the protruding plate (331) inserted into the coupling groove (113), the position of the lens (300) can be adjusted by the first guide part (310) or the second guide part (320).

[0080] More specifically, the width of the protruding plate (331) may be formed to be smaller than the width of the coupling groove (113). That is, the protruding plate (331) can move in the left and right directions even when inserted into the coupling groove (113). At this time, the width of the protruding plate (331) or the width of the coupling groove (113) may refer to the length in the left and right directions. Accordingly, even when the protruding plate (331) is inserted into the coupling groove (113), the lens (300) can move in the left and right directions by the first guide part (310).

[0081] For example, the lens (300) can first be positioned by the first guide part (310). That is, the lens (300) can be positioned by the first guide part (310) such that the x-axis coordinate representing the left and right direction corresponds to the correct x-axis coordinate among the coordinates representing the correct coupling position. Referring to FIGS. 4 and FIGS. 5 together, the left and right position of the lens (300) can be positioned by the first projection (111) of the rear frame (110) passing through the first guide hole (312) of the first guide part (310).

[0082] More specifically, the first projection (111) can be inserted into the open groove of the first guide hole (312) and consequently seated inside the first guide hole (312). Referring to FIG. 6, the first projection (111) can move downward and consequently be seated inside the first guide hole (312) through the open groove of the first guide hole (312). That is, the lens (300) can be secondarily coupled to the rear frame (110) by the first projection (111) being seated inside the first guide hole (312).

[0083] With the first projection (111) penetrating the first guide hole (312), the position of the lens (300) can be adjusted by the second guide part (320). More specifically, in this case, with the left-right and front-back positions of the lens (300) determined, the up-down position, that is, the position corresponding to the height, can be adjusted.

[0084] That is, the position of the lens (300) can be adjusted so that the y-axis coordinate expressed in the vertical direction by the second guide part (320) corresponds to the accurate y-axis coordinate among the coordinates expressing the accurate coupling position. Referring to FIGS. 4 and 5, the vertical position of the lens (300) can be adjusted by the second projection (112) of the rear frame (110) passing through the second guide hole (322) of the second guide part (320).

[0085] More specifically, the second projection (112) can be inserted from the open groove of the second guide hole (322) and consequently seated inside the second guide hole (322). Referring to FIG. 6, the second projection (112) can move in a lateral direction (left direction in FIG. 6) and consequently be seated inside the second guide hole (322) through the open groove of the second guide hole (322). That is, the lens (300) can be finally coupled to the rear frame (110) by the second projection (112) being seated inside the second guide hole (322).

[0086] Alternatively, for example, the lens (300) may first be positioned by the second guide part (320). That is, the lens (300) may be positioned by the second guide part (320) such that the y-axis coordinate representing the up-down direction corresponds to the correct y-axis coordinate among the coordinates representing the correct coupling position. Referring to FIGS. 4 and FIGS. 5 together, the up-down position of the lens (300) may be adjusted by the second projection (112) of the rear frame (110) penetrating the second guide hole (322) of the second guide part (320).

[0087] More specifically, the second projection (112) can be inserted into the open groove of the second guide hole (322) and consequently seated inside the second guide hole (322). Referring to FIG. 6, the second projection (112) can move in a lateral direction (left direction in FIG. 6) and consequently be seated inside the second guide hole (322) through the open groove of the second guide hole (322). That is, the lens (300) can be secondarily coupled to the rear frame (110) by the second projection (112) being seated inside the second guide hole (322).

[0088] With the second projection (112) penetrating the second guide hole (322), the position of the lens (300) can be adjusted by the first guide part (310). More specifically, in this case, the left and right positions can be adjusted while the up and down positions and the front and back positions of the lens (300) are determined.

[0089] That is, the position of the lens (300) can be adjusted so that the x-axis coordinate expressed in the left-right direction by the first guide part (310) corresponds to the correct x-axis coordinate among the coordinates expressing the correct coupling position. Referring to FIGS. 4 and 5, the left-right position of the lens (300) can be adjusted by the first projection (111) of the rear frame (110) passing through the first guide hole (312) of the first guide part (310).

[0090] More specifically, the first projection (111) can be inserted from the open groove of the first guide hole (312) and consequently seated inside the first guide hole (312). Referring to FIG. 6, the first projection (111) can move downward and consequently be seated inside the first guide hole (312) through the open groove of the first guide hole (312). That is, the lens (300) can be finally coupled to the rear frame (110) by the first projection (111) being seated inside the second guide hole (312).

[0091] Accordingly, when the smart glasses (1000) according to the embodiments intend to insert and combine the lens (300) into the rear frame (110), the position in the left-right direction, the position in the up-down direction, and the position in the front-back direction can all be adjusted to correspond to the correct combination position by means of the first guide part (310), the second guide part (320), and the third guide part (330) formed on the lens (300).

[0092] Accordingly, the smart glasses (1000) according to the embodiments have the effect of reducing the occurrence of misalignment or deviation when the lens (300) is joined by accurately joining the rear frame (110) of the lens (300).

[0093] FIG. 7 is a drawing showing the lens (300) of smart glasses (1000) according to embodiments.

[0094] Referring to FIG. 7, the lens (300) may be formed as a pair (300-1, 300-2) as described above. Both the first lens (310-1) and the second lens (310-2) may include a first guide portion (310-1, 310-2). Additionally, although not shown in FIG. 7, both the first lens (310-1) and the second lens (310-2) may include not only the first guide portion (310-1, 310-2) but also the second guide portion (320) and the third guide portion (330) described in FIG. 5.

[0095] Additionally, the lens (300) may include connecting parts (340-1, 340-2).

[0096] The connecting portions (340-1, 340-2) may be formed by protruding from the outer surface of the lens (300). More specifically, the first connecting portion (340-1) may be formed by protruding from the outer surface of the first lens (300-1) toward the second lens (300-2), and the second connecting portion (340-2) may be formed by protruding from the outer surface of the second lens (300-2) toward the first lens (300-1). For example, as shown in FIG. 7, the first connecting portion (340-1) may be formed by protruding to the right from the upper surface of the first lens (300-1), and the second connecting portion (340-2) may be formed by protruding to the left from the upper surface of the second lens (300-2).

[0097] The first lens (300-1) and the second lens (300-2) can be connected to each other by the first connecting part (340-1) and the second connecting part (340-2). That is, by combining the first connecting part (340-1) and the second connecting part (340-2) with each other, the first lens (300-1) and the second lens (300-2) can be combined as a result.

[0098] A first connecting part (340-1) and a second connecting part (340-2) may each have a through groove (342-1) and a through part (342-2) formed therein to be joined to each other. For example, as shown in FIG. 7, the first connecting part (340-1) may include a through groove (342-1) formed on a first plate (341-1), and the second connecting part (340-2) may include a through part (342-2) formed on a second plate (341-2) and penetrating the through groove (342-1).

[0099] Additionally, the first connecting part (340-1) may include a first through hole (343-1) formed on the first plate (341-1), and the second connecting part (340-2) may include a second through hole (343-2) formed on the second plate (341-2). By fixing the first through hole (343-1) and the second through hole (343-2) using a screw member or the like, the first lens (300-1) and the second lens (300-2) can be fixed.

[0100] Accordingly, the smart glasses (1000) according to the embodiments can first combine a pair of lenses (300) by combining the connecting portions (340-1, 340-2) formed on each of the pair of lenses (300), and then combine the combined lenses (300) to the rear frame (110).
