[0011] Hereinafter, AR glasses according to each embodiment will be described with reference to the drawings. For ease of understanding, the drawings will depict an X-axis, a Y-axis, and a Z-axis that are orthogonal to each other, as necessary. The direction along the X-axis will be referred to as the X-direction, the direction along the Y-axis will be referred to as the Y-direction (first direction), and the direction along the Z-direction will be referred to as the Z-direction. Viewing various elements parallel to the Z-direction is referred to as a planar view, and viewing various elements in the YZ plane defined by the Y-direction and Z-direction is referred to as a cross-sectional view.

[0012] Fig. 1 is a schematic perspective view of AR glasses 1 according to an embodiment. Fig. 2 is a schematic top view of the AR glasses 1. Fig. 3 is a schematic side view of the AR glasses 1. Fig. 4 is a schematic back view of the AR glasses 1.

[0013] As shown in Figures 1 to 4, the AR glasses 1 include a frame 10, lenses 20R, 20L, end pieces 30R, 30L, temples 40R, 40L, tip cells 50R, 50L, cushions 60R, 60L, and nose pads 70.

[0014] The frame 10 has rims 11R, 11L and a bridge 12. The rims 11R, 11L are aligned along the X direction. The rims 11R, 11L have an annular shape and hold the lenses 20R, 20L, respectively. In one example, the lenses 20R, 20L are fixed to the rims 11R, 11L by fitting into grooves provided in the rims 11R, 11L. In the example shown in FIG. 4, the frame 10 has multiple grooves 13 (third grooves). The multiple grooves 13 are used to attach diopter adjustment lenses 100 (see FIG. 15), which will be described later.

[0015] The bridge 12 connects the rims 11R and 11L. In one example, the rims 11R and 11L and the bridge 12 are integrally formed. The nose pad 70 is attached to the bridge 12. Details of the nose pad 70 will be described later.

[0016] The end pieces 30R, 30L are connected to the ends of the frame 10. The end piece 30R has a frame 31R and a cover 32R. The end piece 30L has a frame 31L and a cover 32L. The frames 31R, 31L extend in the Y direction and are connected to the rims 11R, 11L, respectively. The covers 32R, 32L are attached to the frames 31R, 31L, respectively. In one example, the frames 31R, 31L and the frame 10 are integrally formed.

[0017] The temple 40R has a frame 41R and a hinge 42R. The temple 40L has a frame 41L and a hinge 42L. The frames 41R and 41L each extend in the Y direction. The hinge 42R connects the frame 41R to the frame 31R of the end piece 30R. The hinge 42L connects the frame 41L to the frame 31L of the end piece 30L. The hinges 42R and 42L support the frames 41R and 41L, respectively, so that they can rotate around an axis along the Z direction. The temples 40R and 40L can be folded by rotating the frames 41R and 41L, respectively.

[0018] The tip cells 50R, 50L are portions that rest on the user's ears when the user wears the AR glasses 1. The tip cell 50R is connected to the frame 41R of the temple 40R. The tip cell 50L is connected to the frame 41L of the temple 40L. The tip cells 50R, 50L are curved to fit the shape of the user's head. Note that the frame 41R and the tip cell 50R, and the frame 41L and the tip cell 50L may be integrally formed.

[0019] As shown in FIGS. 1 and 2, the tip cell 50R includes an inner surface 50Rs. The tip cell 50L also includes an inner surface 50Ls. The inner surfaces 50Rs, 50Ls (first surfaces) are surfaces that face the user's head when the user wears the AR glasses 1. Cushions 60R, 60L are attached to the inner surfaces 50Rs, 50Ls, respectively. The cushions 60R, 60L come into contact with the user's head when the user wears the AR glasses 1. The cushions 60R, 60L are made of a material with excellent cushioning properties. In one example, the cushions 60R, 60L are made of polyurethane.

[0020] 2 and 3, the chip CP is built into the temple 40L. The chip CP includes, for example, a processing device such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), a memory such as a ROM (Read Only Memory) or a RAM (Random Access Memory), and a video signal conversion IC. The chip CP may also be built into the temple 40R.

[0021] 4, light sources LSR and LSS are built into the rims 11R and 11L, respectively. The light sources LSR and LSL emit image light that displays an image toward the lenses 20R and 20L, for example, and project the image onto the lenses 20R and 20L. The light sources LSR and LSL are controlled by the CPU of the chip CP.

[0022] 4, a plurality of internal components PA, including, for example, an FPC (Flexible Printed Circuit) that supplies voltages and signals for driving the AR glasses 1, are built into the frame 10. In addition, components such as a camera and an LED (Light Emitting Diode) may be attached to the frame 10.

[0023] In addition to the above-mentioned elements, the AR glasses 1 may also include elements such as a battery, a sensor, a microphone, a speaker, etc. These elements may be built into the AR glasses 1 or may be externally attached to the AR glasses 1.

[0024] FIG. 5 is an enlarged perspective view of the tip cell 50R and the cushion 60R. The tip cell 50R has a first portion 51R and a second portion 52R. The first portion 51R is located on the side of the tip cell 50R that faces the user's head when the user wears the AR glasses 1. The first portion 51R includes an inner surface 50Rs. The second portion 52R is located outside the first portion 51R. The cushion 60R is attached to the first portion 51R.

[0025] The first portion 51R is formed of, for example, a resin material. In one example, the first portion 51R is formed of polycarbonate. The second portion 52R is formed of, for example, an elastic material. In one example, the second portion 52R is formed of elastomer. The first portion 51R is formed of, for example, a material having higher rigidity than the second portion 52R.

[0026] Fig. 6 is an enlarged top view of the tip cell 50R and the cushion 60R. Note that the tip cell 50R and the cushion 60R are shown separately in Fig. 6. The tip cell 50R includes an end E50a connected to the temple 40R and an end E50b opposite to the end E50a.

[0027] The first portion 51R has a tapered groove 53R (first groove). The groove 53R is provided on the inner surface 50Rs side. The groove 53R becomes deeper from the end E50b toward the end E50a.

[0028] The cushion 60R is attached to the groove 53R. In one example, the cushion 60R is adhered to the groove 53R with double-sided tape. The width of the cushion 60R increases from the end E50b toward the end E50a. That is, the width W60a of the cushion 60R on the end E50a side is greater than the width W60b of the cushion 60R on the end E50b side (W60a>W60b).

[0029] Although not shown in the drawings, the configurations of the front cell 50L and the cushion 60L are similar to the configurations of the front cell 50R and the cushion 60R described above with reference to FIGS.

[0030] 7 is a schematic perspective view of the nose pad 70. The nose pad 70 has a sheet metal member 71 and pads 77R and 77L.

[0031] Sheet metal member 71 has arm portions 72R, 72L, locking portions 73R, 73L, a connecting portion 74, a leaf spring portion 75, and a locking portion 76. In the example shown in Fig. 7, arm portions 72R, 72L, connecting portion 74, leaf spring portion 75, and locking portion 76 are integrally formed. However, each element may be formed from a separate part.

[0032] The arm portion 72R extends from the connecting portion 74 toward the locking portion 73R, and connects the connecting portion 74 and the locking portion 73R. The locking portion 73R is disposed at the end of the arm portion 72R and is formed in a C-shape.

[0033] The arm 72L extends from the connecting portion 74 toward the locking portion 73L, and connects the connecting portion 74 to the locking portion 73L. The locking portion 73L is disposed at the end of the arm 72L and is formed in a C-shape.

[0034] The connecting portion 74 connects the arms 72R and 72L. The leaf spring portion 75 and the locking portion 76 are connected to the connecting portion 74. The leaf spring portion 75 extends in the Z direction and is bent at its tip into a U-shape. The leaf spring portion 75 is inserted into a groove (groove portion 17 shown in Figure 8) provided in the bridge 12, thereby fixing the nose pad 70 to the bridge 12. The locking portion 76 extends in the Y direction and is bent at its tip into a U-shape. The locking portion 76 is used to connect a diopter adjustment lens 100 (see Figure 17), which will be described later.

[0035] The pad 77R has a nose pad 78R and a protrusion 79R protruding from the nose pad 78R. The pad 77L has a nose pad 78L and a protrusion 79L protruding from the nose pad 78L. The nose pads 78R, 78L are components that come into contact with the user's nose when the user wears the AR glasses 1. The protrusions 79R, 79L are locked by the locking portions 73R, 73L, respectively. This fixes the pads 77R, 77L to the sheet metal member 71.

[0036] Fig. 8 is a schematic cross-sectional view of the AR glasses 1 taken along line VIII-VIII in Fig. 2. Fig. 8 shows a cross-section of the area surrounding the connection between the nose pad 70 and the bridge 12. Note that in Fig. 8, pad 77R of the nose pad 70 is indicated by a dashed line.

[0037] The bridge 12 has a groove 17 extending in the Z direction. The groove 17 is located in the lower part of the bridge 12. The leaf spring portion 75 of the nose pad 70 is inserted into the groove 17, thereby fixing the nose pad 70 to the bridge 12.

[0038] The arm 72R includes a first arm 72Ra and a second arm 72Rb. In the example shown in Fig. 8, the first arm 72Ra extends in a direction D1 (second direction) that intersects with the Y direction and the Z direction in a cross-sectional view. The direction D1 is inclined clockwise at an angle θ1 (first angle) with respect to the Y direction. The locking portion 73R is connected to one end of the first arm 72Ra, and the second arm 72Rb is connected to the other end. In the example shown in Fig. 8, a connection portion P1 where the first arm 72Ra and the second arm 72Rb are connected is parallel to the Y direction.

[0039] In the example shown in Fig. 8, the second arm 72Rb extends in the Z direction in a cross-sectional view. The second arm 72Rb connects the first arm 72Ra and the connecting portion 74. In the example shown in Fig. 8, the connecting portion P2 where the second arm 72Rb and the connecting portion 74 are connected is parallel to the Y direction.

[0040] Here, the length of arm portion 72R in direction D1 is defined as length L1, and the length of connecting portion P1 and connecting portion P2 in the Z direction is defined as length L2. In this case, length L1 is 14 mm or less, length L2 is 10 mm or less, and angle θ1 is 20° or more.

[0041] Although not shown, the configurations of the arm portion 72L and the locking portion 73L are similar to the configurations of the arm portion 72R and the locking portion 73R described above with reference to FIG.

[0042] Fig. 9 is an enlarged plan view of a portion of the hinge 42L of the temple 40L, showing the portion of the hinge 42L that is connected to the frame 31L of the end piece 30L.

[0043] Hinge 42L (support portion) has blade portion 43L. In the example shown in Fig. 9, the width of the tip portion of blade portion 43L in the Z direction decreases as it approaches the end of blade portion 43L in the Y direction.

[0044] Blade 43L has a through hole 44L and a protrusion 46L. Through hole 44L penetrates blade 43L in the X direction. As shown in the cross-sectional view of the vicinity of protrusion 46L in the lower part of FIG. 9, protrusion 46L extends in the Y direction and is formed convexly in the X direction. In the example shown in FIG. 9, protrusion 46L is located on axis AX1 that passes through the center of through hole 44L and is parallel to the Y direction, and extends along axis AX1.

[0045] 10 is an enlarged plan view of a portion of the frame 31L of the end piece 30L, showing the portion of the frame 31L that is connected to the hinge 42L of the temple 40L shown in FIG.

[0046] The frame 31L has a recess 33L, a protrusion 34L, a screw hole 35L, and grooves 36La, 36Lb, and 36Lc (second grooves). The recess 33L is provided at the end of the frame 31L on the side where the temple 40L is connected, and is formed concave in the X direction. The recess 33L is covered by the cover 32L shown in FIG. 1. The protrusion 34L is formed convex in the X direction. The protrusion 34L has a shape in which a portion of the side of a cylinder is cut out. The screw hole 35L is provided at the top of the protrusion 34L. The protrusion 34L and the screw hole 35L are arranged concentrically.

[0047] As shown in the cross-sectional view of the periphery of groove 36La shown in the lower part of Figure 10, groove 36La is recessed in the X direction. Grooves 36Lb and 36Lc are also recessed in the X direction like groove 36La.

[0048] The grooves 36La, 36Lb, and 36Lc extend in different directions. Specifically, the groove 36La is located on an axis AX2a that passes through the centers of the protrusion 34L and the screw hole 35L and is parallel to the Y direction, and extends along the axis AX2a. The groove 36Lb is located on an axis AX2b that passes through the centers of the protrusion 34L and the screw hole 35L and is tilted counterclockwise by an angle θb with respect to the axis AX2a, and extends along the axis AX2b. The groove 36Lc is located on an axis AX2c that passes through the centers of the protrusion 34L and the screw hole 35L and is tilted clockwise by an angle θc with respect to the axis AX2a, and extends along the axis AX2c.

[0049] In the example shown in Fig. 10, angle θb is equal to angle θc (θb = θc). Note that angles θb and θc may be different from each other. Furthermore, in the example shown in Fig. 10, three grooves 36La, 36Lb, and 36Lc are formed in frame 31L, but four or more grooves may be formed in frame 31L.

[0050] 11 to 13 are plan views showing the end piece 30L and temple 40L in a combined state. FIG. 11 shows the state in which the protrusion 46L is fitted into the groove 36La. FIG. 12(a) shows the state in which the protrusion 46L is fitted into the groove 36Lb. FIG. 12(b) is a side view of the AR glasses 1 in a state in which the protrusion 46L is fitted into the groove 36Lb. FIG. 13(a) shows the state in which the protrusion 46L is fitted into the groove 36Lc. FIG. 13(b) is a side view of the AR glasses 1 in a state in which the protrusion 46L is fitted into the groove 36Lc.

[0051] 11, 12(a), and 13(a), the protrusion 34L is inserted into the through-hole 44L. In this state, the frame 31L and the hinge 42L are connected by inserting a screw (not shown) into the screw hole 35L. This allows the frame 31L and the hinge 42L to rotate about the protrusion 34L.

[0052] As shown in FIGS. 11 to 13, the angle of the temple 40L can be adjusted by fitting the protrusion 46L into one of the grooves 36La, 36Lb, and 36Lc.

[0053] Although not shown in the drawings, the configurations of the end piece 30R and the temple 40R are the same as the configurations of the end piece 30L and the temple 40L described above with reference to FIGS.

[0054] In this embodiment, the first engagement portion corresponds to the protrusion 46L, and the multiple second engagement portions correspond to the grooves 36La, 36Lb, and 36Lc. Note that the first engagement portion may be a groove, and the multiple second engagement portions may be multiple protrusions.

[0055] 14 is an enlarged top view of the periphery of the tip CP. The frame 41L of the temple 40L includes an inner surface 41Li (second surface) and an outer surface 41Lo (third surface) opposite the inner surface 41Li. The inner surface 41Li is the surface that faces the user's head when the user wears the AR glasses 1. The tip CP includes an inner surface CPi on the inner surface 41Li side and an outer surface CPo on the outer surface 41Lo side.

[0056] The chip CP is located on the outer surface 41Lo side of the frame 41L. Specifically, the distance Lo between the outer surface 41Lo and the outer surface CPo is smaller than the distance Li between the inner surface 41Li and the inner surface CPi (Lo <Li)。

[0057] 15 is a rear view of AR glasses 1 according to another embodiment equipped with diopter-adjusting lenses 100. The diopter-adjusting lenses 100 are attached to the inside of the AR glasses 1 (the side facing the user when wearing the AR glasses 1). By wearing the AR glasses 1 equipped with the diopter-adjusting lenses 100, even a user with poor eyesight can clearly view AR images.

[0058] The diopter-adjusting lens 100 has diopter lenses 110R, 110L, a frame 120, and a plurality of hooks 130. The diopter lenses 110R, 110L are prescription lenses, and the curvature of the lenses is set according to, for example, the user's eyesight. The frame 120 secures the diopter lenses 110R, 110L. The plurality of hooks 130 are attached to the frame 120. The diopter-adjusting lens 100 is attached to the frame 10 by fitting the plurality of hooks 130 into a plurality of grooves 13 provided in the frame 10.

[0059] FIG. 16 is a schematic perspective view of the diopter adjusting lens 100. As shown in FIG. The frame 120 has a locking portion 140. The locking portion 140 is located between the diopter lenses 110R and 110L. In one example, the locking portion 140 is formed by bending a part of the frame 120 into a U-shape.

[0060] The plurality of hooks 130 are formed in an L-shape and attached to the frame 120. In one example, the frame 120 and the plurality of hooks 130 are integrally formed. Note that the positions and number of the plurality of hooks 130 are not limited to the example shown in the drawing.

[0061] Fig. 17 is a schematic perspective view showing the state in which the nose pads 70 and the diopter-adjusting lens 100 are connected. As shown in Fig. 17, the locking portions 76 of the nose pads 70 are locked with the frame 120 of the diopter-adjusting lens 100, and the connecting portions 74 of the nose pads 70 are locked with the locking portions 140 of the diopter-adjusting lens 100, thereby connecting the nose pads 70 and the diopter-adjusting lens 100. In this state, the leaf spring portions 75 of the nose pads 70 are inserted into the grooves 17 of the bridge 12, and the multiple hooks 130 are inserted into the multiple grooves 13, thereby connecting the nose pads 70 and the diopter-adjusting lens 100 to the frame 10.

[0062] FIG. 18 is a diagram showing the state when the AR glasses 1 are in use. FIG. 18(a) is a schematic rear view of the AR glasses 1 in a state in which an AR image AP is displayed. FIG. 18(b) is a diagram showing an example of an image that the user can see through the AR glasses 1. Note that FIG. 18(a) shows only the right side of the AR glasses 1, but the AR image AP is also displayed on the left side of the AR glasses 1 in the same way as on the right side.

[0063] 18(a), the AR image AP is projected directly onto the lens 20R by emitting image light to the lens 20R from a light source LSR built into the AR glasses 1. Note that the projection method of the AR image AP is not limited to the above example.

[0064] When a user wears the AR glasses 1 in the state shown in Fig. 18(a), the user can view the real space RS through the area of ​​the lens 20R where the AR image AP is not projected. Therefore, as shown in Fig. 18(b), the user can simultaneously view both the AR image AP and the real space RS, with the AR image AP overlapping the real space RS. In the example of Fig. 18(b), the user can simultaneously view both the indoor real space RS and the AR image AP of a landscape with flowers and other images.

[0065] Here, because various components are mounted on the frame 10 of the AR glasses 1, the center of gravity of the AR glasses 1 may be shifted forward, which may cause the AR glasses 1 to shift during use. If the AR glasses 1 shift, a situation may occur in which part of the AR image AP becomes invisible.

[0066] In this embodiment, cushions 60R, 60L are attached to the tip cells 50R, 50L, which increases the clamping force on the user's head, making it possible to prevent the AR glasses 1 from shifting when in use, and improving the wearability of the AR glasses 1.

[0067] Furthermore, the cushions 60R, 60L are made of a material with excellent cushioning properties, such as polyurethane. This allows for increased clamping force without making the user feel as if they are being tightly clamped by the AR glasses 1. As a result, the comfort of wearing the AR glasses 1 can be improved.

[0068] Furthermore, the first portions 51R, 51L to which the cushions 60R, 60L are adhered are formed of a material that is more rigid than the second portions 52R, 52L, which are formed of an elastic material. Therefore, compared to when both the first portions 51R, 51L and the second portions 52R, 52L are formed of an elastic material, the adhesive strength of the cushions 60R, 60L is improved. Also, by using an elastic material for the portions of the tip cells 50R, 50L other than those to which the cushions 60R, 60L are adhered, the elasticity of the tip cells 50R, 50L can be ensured, and the comfort of the AR glasses 1 can be prevented from decreasing.

[0069] Furthermore, as shown in FIG. 6, the tip cell 50R has a groove 53R that becomes deeper from the end E50b toward the end E50a. The cushion 60R becomes thicker from the end E50b toward the end E50a. Increasing the thickness of the cushion 60R in the portion that comes into strong contact with the user's temples increases the cushioning properties and improves the fit of the AR glasses 1. Furthermore, increasing the thickness of the cushion 60R makes it possible to reduce variations in the fit of the AR glasses 1 even if the size and shape of the head differs from user to user.

[0070] Furthermore, in this embodiment, the lengths L1, L2 and extension angle θ1 of the arms 72R, 72L of the nose pad 70 are in the relationship described above. This positional relationship brings the lenses 20R, 20L closer to the user's eyes, preventing a situation in which part of the AR image AP becomes invisible even if the AR glasses 1 are slightly misaligned. As a result, it is possible to prevent a decrease in the visibility of the AR image AP.

[0071] Furthermore, in this embodiment, as shown in FIGS. 11 to 13, the angle of the temple 40L can be adjusted by fitting the protrusion 46L on the temple 40L into one of the grooves 36La, 36Lb, and 36Lc on the end piece 30L. Therefore, even if the user's nose height or ear position varies, the positions of the lenses 20R and 20L can be kept horizontal. As a result, it is possible to prevent a situation in which part of the AR image AP becomes invisible due to misalignment of the AR glasses 1, and it is possible to suppress a decrease in the visibility of the AR image AP.

[0072] 14, the tip CP is disposed on the outside of the temple 40L. That is, the tip CP is disposed on the temple 40L at a position far from the user and difficult to touch. Therefore, even if the tip CP becomes hot during use, dangers such as low-temperature burns can be avoided.

[0073] Furthermore, in this embodiment, the diopter adjusting lens 100 can be attached to the frame 10. Therefore, even a user with poor eyesight can use the AR glasses 1 without wearing eyeglasses.

[0074] Furthermore, the diopter-adjusting lens 100 is attached to the frame 10 by engaging the multiple hooks 130 with the multiple grooves 13 provided on the frame 10, and the leaf spring portion 75 of the nose pad 70 to which the diopter-adjusting lens 100 is attached with the groove 17 of the bridge 12. By fixing the diopter-adjusting lens 100 at multiple points in this way, it is possible to firmly fix the diopter-adjusting lens 100 to the frame 10. This makes it possible to prevent the diopter-adjusting lens 100 from shifting while the AR glasses 1 are in use.

[0075] The present invention is not limited to the above-described embodiments, and the components can be modified and embodied in practice without departing from the spirit of the invention. Furthermore, various inventions can be formed by appropriately combining multiple components disclosed in the above embodiments. For example, some components may be omitted from all the components shown in the embodiments. Furthermore, components from different embodiments may be appropriately combined.
