[0005] Patent Document 1: Japanese Patent No. 6216000 Summary of the invention
[0006] Technical issues
[0007] In this way, there is a need for a technology that can improve the convenience of a user who uses a head-mounted display.
[0008] In view of the circumstances as described above, the present technology aims to provide a head-mounted display capable of improving user convenience.
[0009] Solution to the problem
[0010] In order to achieve the above-mentioned object, a head-mounted display according to an embodiment of the present technology includes a first member, a second member, and a fixing member.
[0011] The first member includes a first pad that contacts a first portion of the user's face.
[0012] The second member includes a second pad that contacts a second portion of the user's face that is different from the first portion.
[0013] The fixing member is capable of fixing the second member to the first member, and is configured so that the fixing of the second member to the first member is released when a predetermined operation is performed by a user.
[0014] In the head mounted display, the second member is fixed to the first member by the fixing member. In addition, the fixing of the second member to the first member is released when a predetermined operation is performed by the user. Therefore, user convenience can be improved.
[0015] The fixing member may include a claw member connected to the second member, latched to the first member, and configured so as to be released from latching relative to the first member when a predetermined operation is performed.
[0016] The second member may include a fixed side member and a moving side member, the fixed side member being fixed to the first member through the fixing member, and the moving side member being movably connected to the fixed side member. In this case, the predetermined operation may include an operation of moving the moving side member relative to the fixed side member.
[0017] The moving-side member may be movably connected to the fixed-side member via a spring.
[0018] The fixed member may include a claw member that is movably connected to the fixed side member, latched to the first member, and configured so that the latch relative to the first member is released when a predetermined operation is performed. In this case, the mobile side member may include a pressing member that presses the claw member according to an operation that moves the mobile side member relative to the fixed side member so that the latch of the claw member relative to the first member is released.
[0019] The claw member may be rotatably connected to the fixed side member. In this case, the pressing member may press the claw member according to the operation of moving the moving side member relative to the fixed side member so that the claw member rotates in the direction in which the latch of the claw member relative to the first member is released.
[0020] The first member can be attached to the forehead of the user as the first part via the first pad. In this case, the second member can be attached to the cheek of the user as the second part via the second pad.
[0021] The head mounted display may further include a link mechanism that rotatably connects the second member to the first member. In this case, the link mechanism may connect the first member and the second member to each other so that a rotation operation can be performed, which is an operation in which the second member whose fixation with respect to the first member has been released is rotated from a basic use state of the head mounted display in an upward flipping direction in which the rotation angle of the second member is increased.
[0022] In the basic use state, the link mechanism may be arranged in a region of each of the first member and the second member on the user's face side.
[0023] The link mechanism may include a spring that biases the second member according to the rotation operation.
[0024] When the rotation angle of the second member is less than a predetermined angle, the spring included in the link mechanism may bias the second member to rotate in a downward flipping direction in which the rotation angle of the second member becomes smaller, and when the rotation angle of the second member becomes greater than the predetermined angle, the spring included in the link mechanism may bias the second member to rotate in an upward flipping direction.
[0025] The maximum value of the load of the spring in the rotating operation may be 4.8 N or more and 7.2 N or less.
[0026] In the downward flipped state in which the second member is fixed to the first member, the spring can bias the second member relative to the first member. In this case, the maximum value of the load of the spring in the downward flipped state can be 1.6N or more and 2.4N or less.
[0027] The linkage mechanism may include a hinge mechanism.
[0028] The head mounted display may further include one shaft member rotatably connecting the second member to the first member. In this case, the one shaft member may connect the first member and the second member to each other so that a rotation operation can be performed, in which the second member whose fixation relative to the first member has been released is rotated from a basic use state of the head mounted display in an upward flipping direction in which the rotation angle of the second member is increased.
[0029] The head mounted display may further include a planar upper surface positioned on the upper side in a basic use state of the head mounted display. In this case, the first pad may be configured not to protrude from the upper surface.
[0030] The head mounted display may further include an operating element for releasing the fixation of the second member relative to the first member. In this case, the predetermined operation may include the operation of the operating element.
[0031] The first member may include an attachment portion for attaching a strap to be worn on a user's head.
[0032] The head mounted display may further include a display unit that displays an image. In this case, the second member may hold the display unit.
[0033] A head-mounted display according to an embodiment of the present technology includes a first member, a second member, and a fixing structure.
[0034] The first member includes a first pad that contacts a first portion of the user's face.
[0035] The second member includes a light shielding member that contacts a second portion of the user's face that is different from the first portion so as not to receive a load from the second portion.
[0036] The fixing structure removably fixes the second member to the first member. BRIEF DESCRIPTION OF THE DRAWINGS

[0100] Figure 7 2 is a schematic diagram showing a configuration example of the lower block 18 , the lower metal sheet 22 , and the slide spring 24 .
[0101] Figure 7 The figure shows the state where the lower pad 18, the lower metal sheet 22 and the sliding spring 24 are viewed from the front. Figure 7 In the figure, components other than the lower pad 18, the lower metal sheet 22 and the sliding spring 24 are shown with transparent lines.
[0102] The lower metal sheet 22 is an auxiliary member for slidably connecting the lower shell 20 to the lower pad 18. The lower metal sheet 22 has a generally rectangular plate shape, and its generally rectangular surface is arranged to be parallel to the YZ plane. In addition, a total of three holes are formed at the corners on the positive side of the Z axis and the positive side of the Y axis, the lower side of the edge on the positive side of the Z axis, and the center of the lower edge in the Z direction. The lower metal sheet 22 is arranged so that the holes overlap with the screw receiving portions 37 of the lower shell 20, respectively. In other words, the screws pass through the holes of the lower metal sheet 22 to cooperate with the threads provided in the screw receiving portions, and thus the lower metal sheet 22 is connected to the lower shell 20. Figure 7 , three screws are schematically shown in black cylindrical shapes.
[0103] In addition, two holes each having a substantially elliptical shape are formed in the lower metal sheet 22. Two protrusions 33 formed on the inner (negative side of the X-axis) surface of the plate-shaped portion of the lower base 28 are fitted into the two holes. In addition, a circular hole is formed at the lower portion of the lower metal sheet 22. The lower metal sheet 22 is formed of a material such as metal, for example. In addition to these, the specific configuration of the lower metal sheet 22 including the material, shape, etc. is not limited.
[0104] The sliding spring 24 is a spring for connecting the lower pad 18 and the lower pad metal sheet 22. One end of the sliding spring 24 is hooked to a hole provided at an end of a spring fixing metal sheet 30 provided in the lower pad 18. In addition, the other end of the sliding spring 24 is hooked to a hole provided at a lower portion of the lower pad metal sheet 22. Therefore, the lower pad 18 and the lower pad metal sheet 22 are connected via the sliding spring 24.
[0105] Since the lower pad metal sheet 22 is fastened to the lower housing 20 by screws, it can also be said that the lower pad 18 and the lower housing 20 are connected via the sliding spring 24. The specific configuration of the sliding spring 24 including the length, material, etc. is not limited. The sliding spring 24 corresponds to an embodiment of the spring according to the present technology, which movably connects the moving side member to the fixed side member.
[0106] Note that the lower pad metal sheet 23 and the slide spring 25 are also similarly formed on the right side of the head mounted display 1 (near the lower pad 19). Except for these, the specific configuration of the entire movable side front block 3 is not limited. The movable side front block 3 corresponds to an embodiment of the second member according to the present technology.
[0107] The display 4 is a display device using, for example, liquid crystal, EL (electroluminescence), etc., on which various images, various GUIs (graphical user interfaces), etc. are displayed. In the present embodiment, the user observes the video displayed on the display 4. By observing the display 4, an AR experience or a VR experience may become possible.
[0108] The display 4 is attached to the optical block 21 on the left and right sides. In other words, the display 4 is held by the movable side front block 3. When the user is wearing the head mounted display 1, the optical block 21 and the display 4 are set at positions opposite to both eyes of the user. The display 4 corresponds to an embodiment of a display unit that displays an image according to the present technology.

The plate member 55 is arranged parallel to the YZ plane, and includes two holes (guide holes) for passing the shaft 50 therethrough.
[0115] The left base portion 53 has a configuration that is bilaterally symmetrical with the right base portion 52 , and is arranged to be bilaterally symmetrical with the right base portion 52 .
[0116] The lower link base 47 is a member that becomes a base for the link mechanism block 5. The lower link base 47 includes an L-shaped member 56 and a plate member 57. The L-shaped member 56 has a shape in which a rectangular plate shape is bent into an L shape, and is arranged so that the bottom surface of the L shape becomes parallel to the XZ plane and the side surface becomes parallel to the XY plane.
[0117] Screw holes are formed at four corners of the side surface of the L-shaped member 56, respectively, so that screws pass through the screw holes to fit into the screw holes provided in the lower housing 20. Thus, the lower link base 47 is connected to the lower housing 20. Note that the lower link base 47 may also be connected to the optical block 21 or the like. Two convex portions protruding in the left-right direction for hooking the link spring 51 are formed at the side portion (including the portion of the side surface). In addition, four screw holes are formed on the bottom surface.
[0118] The plate member 57 has a shape in which an isosceles trapezoidal plate shape is bent perpendicularly along lines passing through the ends of the upper base (the shorter of the two base portions) of the trapezoid and perpendicular to the upper base and the lower base, respectively. In other words, the plate member 57 includes a rectangular bottom surface and two side surfaces each having a right-angled triangle shape.
[0119] Four holes for passing screws therethrough are formed on the bottom surface of the plate member 57. The plate member 57 is arranged so that the four holes formed on the bottom surface overlap with the four screw holes formed on the bottom surface of the L-shaped member 56. Then, by fastening with screws, the L-shaped member 56 is connected to the plate member 57. In addition, two holes (guide holes) for passing the shaft 50 are formed on each of the two side surfaces of the plate member 57.
[0120] The upper connecting rod 48 is a connecting rod constituting a connecting rod mechanism. The upper connecting rod 48 has a columnar shape, and the upper surface and the lower surface each have a shape in which the center of the rod shape with both ends unfolded in a circular shape is bent only by an amount corresponding to the acute angle, so that the angle after bending becomes an obtuse angle. A through hole for passing the shaft 50 therethrough is formed at the circular portion of the upper surface and the lower surface. In other words, two through holes communicating between the upper surface and the lower surface are formed in the upper connecting rod 48. The upper connecting rod 48 is arranged so that one of the through holes overlaps with a hole formed in the plate member 55 of the right base 52 and the left base 53. In addition, the upper connecting rod 48 is arranged so that the other through hole in the through hole overlaps with a hole formed on the side surface of the plate member 57 of the lower connecting rod base 47.
[0121] The lower link 49 is a link constituting a link mechanism. The lower link 49 has a columnar shape, and the upper and lower surfaces generally have a rod shape with both ends expanded in a circular shape. Through holes for passing the shaft 50 therethrough are formed at circular portions of the upper and lower surfaces. Similar to the upper link 48, the lower link 49 is arranged so that one of the through holes overlaps with a hole formed in the plate member 55, and the other of the through holes overlaps with a hole formed on the side surface of the plate member 57.
[0122] Each of the four shafts 50 is a rod-shaped member. In the present embodiment, the shaft 50 passes through a hole formed in the plate member 55 of the right base 52, a through hole of the upper link 48, and a hole formed in the plate member 55 of the left base 53. Therefore, the upper link 48 is rotatably connected to the upper link base 46. In addition, the shaft 50 passes through a hole formed on a side surface of the plate member 57 of the lower link base 47 and the through hole of the upper link 48, and therefore the upper link 48 is rotatably connected to the lower link base 47. Similarly, the lower link 49 is rotatably connected to the upper link base 46 and the lower link base 47.
[0123] In other words, if Figures 9 to 11As shown, the upper link base 46 and the lower link base 47 are connected via the upper link 48 and the lower link 49. In addition, the upper link 48 is arranged so as to be suspended on the lower link 49 on the upper side. The upper link base 46, the lower link base 47, the upper link 48, the lower link 49 and the shaft 50 are all formed of a material having rigidity such as metal, but the specific configuration including the material, shape, etc. is of course not limited.
[0124] Each of the two link springs 51 is a spring for connecting the upper link base 46 and the lower link base 47. One end of one of the link springs 51 is hooked to a hole formed in a protrusion of a plate member 54 of the right base 52. The other end is hooked to a right protrusion of an L-shaped member 56 of the lower link base 47. Similarly, the other of the link springs 51 is hooked to a hole of a left base 53 and a left protrusion of the L-shaped member 56. Thus, the upper link base 46 and the lower link base 47 are connected via the two link springs 51.
[0125] The specific configuration of the link mechanism block 5 is not limited except for these. The link mechanism block 5 corresponds to an embodiment of the link mechanism according to the present technology. The link spring 51 corresponds to an embodiment of a spring included in the link mechanism according to the present technology.

[0128] Fig.13 1 is a side view showing the head mounted display 1 in the released state.
[0129] Fig.14 1 is a side view showing the head mounted display 1 being turned upside down.
[0130] Fig.15 1 is a side view showing the head mounted display 1 in a flipped-up state.
[0131] Fig.16 1 is a schematic diagram showing a configuration example of the lower blocks 18 and 19 and the lower metal sheet 22 in a flipped-down state and a released state.
[0132] Figures 12 to 15 1 is a side view showing a state where the head mounted display 1 is viewed from the right side (positive side of the X axis). Fig.12 "A" Fig.13 , Fig.14 and Fig.15 The "A" allows for the main internal components to be viewed. Fig.12 The "B" of FIG. 1 makes it possible to mainly observe the external components such as the upper shell 8 and the lower shell 20. Fig.15 The “B” in FIG. 4 allows the upper link 48 and the lower link 49 to be primarily observed.
[0133] In this embodiment, the user performs an upward flipping operation and a downward flipping operation on the head mounted display 1. Specifically, Fig.12 As shown in FIG. 1 , the state in which the movable side front block 3 is fixed to the fixed side front block 2 and the entire head mounted display 1 is circularly closed is a flipped-down state. Fig.15 As shown, a state in which fixation relative to the fixed-side front block 2 is released and the head mounted display 1 is largely opened while the movable-side front block 3 is positioned farthest from the fixed-side front block 2 is the flipped-up state.
[0134] When the user wears the head mounted display 1, in the flipped-down state, the upper pad 9 contacts the forehead, and the lower pad 29 contacts the cheeks. Next, the length of the band 14 is adjusted so that the back of the head pad 15 contacts the back of the head with an appropriate load. The head mounted display 1 is worn in this manner.
[0135] The head-mounted display 1 can be removed in the flipped-up state or the flipped-down state. In addition, the user can flip the head-mounted display 1 upward while wearing the head-mounted display 1 and check the peripheral view (the view outside the head-mounted display 1). Alternatively, watching a video can be temporarily stopped so that the user can take a rest while flipping the head-mounted display 1 upward.
[0136] [Basic usage status]
[0137] A basic use state of the head mounted display 1 will be described. The basic use state refers to a state of the head mounted display 1 in a case where the user is viewing a video. In the present embodiment, viewing of a video is performed while the head mounted display 1 is flipped down. Therefore, the flipped down state corresponds to the basic use state.
[0138] [Flip up operation]
[0139] A series of operations in the case of flipping up the head mounted display 1 will be described. Hereinafter, regarding a member that performs a similar operation as the lower blocks 18 and 19 and the like, a description of one of the members may be omitted.
[0140] When the upward flipping starts in the downward flipping state ( Fig.12 ), the lower pad 18 and the lower shell 20 are slightly separated from each other ( Fig.13 ). Thereafter, the lower pad 18 and the lower shell 20 are in close contact with each other again, and the fixed side front block 2 and the movable side front block 3 are separated from each other ( Fig.14 Then, the fixed side front block 2 and the movable side front block 3 are separated from each other to a great extent so as to be set in an upward flipped state ( Fig.15).
[0141] exist Fig.12 In the downward flipped state shown, the locking claw 31 is latched by the fixed side front block 2. Specifically, a claw hook portion 13 for hooking the locking claw 31 is formed on the lower side of the upper housing 8, and the upper end of the locking claw 31 is hooked to the claw hook portion 13. Therefore, the movable side front block 3 (lower pad 18) is fixed to the fixed side front block 2. In addition, the claw hook portion 13 also has a function of positioning the locking claw 31, and the locking claw 31 is positioned so that the upper end of the locking claw 31 extends in the up-down direction.
[0142] Note that although the movable-side front block 3 is fixed to the fixed-side front block 2 by the locking claw 31 in the present embodiment, the fixation may alternatively be achieved by a fixing member having a shape other than the claw shape, for example. Furthermore, the specific fixing method is also not limited.
[0143] When receiving the force of the lock spring 32, the lower end of the lock claw 31 is pulled toward the positive side of the Z axis ( Fig.12 ). Therefore, since the upper end of the locking claw 31 attempts to rotate toward the right side, the locking claw 31 is stably latched, and the latch is prevented from being unintentionally disengaged.
[0144] Although it depends on the fastening level of the attachment block 10 on the head, the upper pad 9 and the lower pad 29 receive a load of about 1N to 10N from the user's face. Therefore, the latching amount of the locking claw 31 and the load of the locking spring 32 are set to appropriate values so that the latch of the locking claw 31 does not fall off due to the load. For example, the latching amount of the locking claw 31 is set to about 2mm. In addition, the load of the locking spring 32 is set to about 1N. Of course, the specific values of the latching amount of the locking claw 31 and the load of the locking spring 32 are not limited.
[0145] Furthermore, in the flipped-down state, the claw pressing rib 38 provided in the lower case 20 comes into contact with the receiving surface formed in the locking claw 31 .
[0146] Fig.16 "A" shows the lower pads 18 and 19 and the lower metal sheet 22 in a flipped-down state. Note that Fig.16 The "A" is Figure 4 Same diagram, but for Fig.16 It is shown again by comparison with "B" (released state) in FIG.
[0147] like Fig.16As shown in "A" of FIG. 1 , the lower pad 18 is sandwiched between the lower housing 20 and the lower pad metal sheet 22. In addition, two protrusions 33 formed in the lower pad 18 are fitted into two substantially elliptical holes formed in the lower pad metal sheet 22. The two protrusions 33 are each positioned at the lower portion of the hole. In addition, the lower pad 18 abuts against three screw receiving portions 37 (not shown) provided in the lower housing 20, thereby being positioned.
[0148] like Fig.13 As shown, in the released state, the positions of the fixed side front block 2 and the lower pad 18 are relative to the downward flipped state ( Fig.12 ) has not changed, but the position of the lower shell 20 has changed. Specifically, the lower shell 20 is separated from the lower pad 18 and slightly moved to the left.
[0149] When the user performs a predetermined operation, the state of the head mounted display 1 is changed from the flipped-down state to the released state. In this embodiment, the operation of moving the lower housing 20 relative to the lower pad 18 is performed as the predetermined operation. Of course, the specific content of the predetermined operation is not limited.
[0150] Specifically, the user performs an operation to slide the lower housing 20 counterclockwise around the link mechanism block 5. For example, the lower housing 20 moves downward near the locking claw 31 (negative side of the Y axis). In addition, for example, the portion of the lower housing 20 on the front side (positive side of the Z axis) moves toward the front side. The lower housing 20 is pulled to be in close contact with the lower pad 18 via the sliding spring 24, but the user can separate the lower housing 20 from the sliding spring 24 by sliding the lower housing 20 with a force higher than a certain level. In other words, the lower housing 20 is movably connected to the lower pad 18 via the sliding spring 24.
[0151] The load of the sliding spring 24 is set to a value that sufficiently pulls the lower housing 20 and can be effortlessly moved by the user's operation. Specifically, the value is set to, for example, 1N to 2N (the values for the sliding springs 24 and 25 are 2N to 4N in total). Of course, the specific value of the load of the sliding spring 24 is not limited.
[0152] Note that the method of movably connecting the lower housing 20 to the lower block 18 is not limited to the method via the slide spring 24. For example, the movably connecting may be achieved by other methods such as a method combining a connecting member other than the slide spring 24.
[0153] When the user performs the sliding operation, the locking claw 31 is pressed by the claw pressing rib 38 provided in the lower case 20, so that the locking claw 31 rotates in a direction to release the latch of the locking claw 31 relative to the upper case 8. Specifically, the claw pressing rib 38 moves downward, so that the receiving surface of the locking claw 31 is pressed downward by the claw pressing rib 38. The locking claw 31 rotates counterclockwise, so that the hook relative to the claw hook portion 13 is released.
[0154] Since the lower part of the locking claw 31 is pulled by the locking spring 32, the locking claw 31 rotates when the pressing force of the claw pressing rib 38 exceeds the drawing force of the locking spring 32. The load of the locking spring 32 is set to a value at which the locking claw 31 can rotate effortlessly, for example.
[0155] Note that although the locking claw 31 is rotatably connected to the lower pad 18 in this embodiment, the locking claw 31 may be movably connected in a form other than rotation. For example, the latch relative to the upper housing 8 may be released by simply moving the locking claw 31 to the left.
[0156] Fig.16 "B" shows the lower pads 18 and 19 and the lower metal sheet 22 in the released state. In the released state, each of the two protrusions 33 is positioned at the upper part of the hole of the lower metal sheet 22 by moving the lower pad 18. When the protrusion 33 is positioned at the upper end of the hole in this way, the lower pad 18 and the lower housing 20 will no longer be separated.
[0157] When the latch of the locking claw 31 is released in the released state, the fixing of the upper housing 8 and the lower pad 18 is released to thereby be configured as follows. Fig.14 In this state, the lower portion of the locking claw 31 is pulled by the locking spring 32, so that the locking claw 31 rotates clockwise to return to its initial state again. In addition, the lower pad 18 is pulled into the lower housing 20 by the sliding spring 24, and thereby the lower pad 18 and the lower housing 20 return to the close contact state again.
[0158] In the present embodiment, the movable side front block 3 is rotatably connected to the fixed side front block 2 via the link mechanism block 5. Specifically, the link mechanism block 5 connects the fixed side front block 2 and the movable side front block 3 to each other so that a rotation operation can be performed in which the movable side front block 3, whose fixation relative to the fixed side front block 2 has been released, is rotated from the basic use state of the head mounted display 1 in an upward flipping direction in which the rotation angle of the movable side front block 3 is increased.
[0159] Specifically, in the state of the middle of flipping up, the lower case 20 and the lower pad 18 provided in the movable side front block 3 are connected to the fixed side front block 2 in an integrated manner through the link mechanism block 5. Furthermore, in this state, a rotation operation of rotating the movable side front block 3 in the flip-up direction is possible. In other words, while the movable side front block 3 is rotated clockwise using the link mechanism block 5 as a rotation axis, the position of the entirety of the movable side front block 3 is gradually changed toward the positive side of the Y axis.
[0160] Fig.15 'A' shows the head mounted display 1 in a state where the upward flipping is completely completed. Fig.15 The state shown by “A” is a state in which the movable side front block 3 is rotated about 120 degrees relative to the fixed side front block 2 and the movable side front block 3 cannot be rotated in the clockwise direction any more.
[0161] When the user flips the head mounted display 1 downward again, the operations are performed in the reverse order of the above operations. Note that in the downward flipping operation, the lower housing 20 will not be separated from the lower pad 18, so the operation will not go through the release state ( Fig.13 ). In other words, the state of the head mounted display 1 changes from the flipped-up state ( Fig.15 ) to the flip-up intermediate state ( Fig.14 ), and then returns to the flipped-down state ( Fig.12 ). Note that in the middle state from flipping up ( Fig.14 ) to the flip-up state ( Fig.12 ), the inclined surface at the upper end portion of the locking claw 31 slides along the claw hook portion 13, and the state is smoothly switched without hooking the locking claw 31.
[0162] Note that in the present embodiment, when the lower housing 20 is rotated about 3 degrees from the flip-down state, the locking claw 31 is rotated about 12 degrees, and the latch of the locking claw 31 is released. Of course, the specific rotation angles of the lower housing 20 and the locking claw 31 are not limited. In addition, the operations during the flip-up and the operations during the flip-down that have been described above are only examples, and the specific contents of these operations are not limited.
[0163] [Operation of the linkage block]
[0164] The operation of the link mechanism block 5 during the rotation of the movable side front block 3 will be described. Fig.12 ) and release state ( Fig.13), the directions of the upper link 48 and the lower link 49 are approximately in the lateral direction (direction parallel to the XZ direction), and the upper link 48 is suspended from the lower link 49 from above. Thereafter, the upper link 48 and the lower link 49 gradually change their directions, and the directions of the upper link 48 and the lower link 49 are in the middle of the upward flipping state ( Fig.14 ) becomes substantially vertical (direction parallel to the XY direction). In addition, the upper link 48 is positioned on the negative side of the Z axis ( Fig.14 ), and the lower link 49 is positioned on the positive side of the Z axis ( Fig.14 on the left side of the image).
[0165] When the head mounted display 1 is completely flipped upward ( Fig.15 The direction of the upper link 48 and the lower link 49 is approximately the lateral direction. At this time, the lower link 49 is suspended from the upper link 48, and the end of the lower link 49 ( Fig.15 The right end portion in "B" of the movable side block 3 is close to the upper surface of the upper link 48. Therefore, the upper link 48 and the lower link 49 can no longer move, and the movable side front block 3 can no longer rotate.
[0166] This state becomes the maximum rotation angle of the movable side front block 3. The maximum rotation angle of the movable side front block 3 can be determined to a desired angle by adjusting the shape and arrangement of the link mechanism block 5. Of course, the maximum rotation angle of the movable side front block 3 is not limited and can be an arbitrary value.
[0167] Furthermore, in the present embodiment, the movable side front block 3 is biased according to the rotation operation by the link spring 51. The link spring 51 biases the movable side front block 3 to rotate in the downward flipping direction in which the rotation angle of the movable side front block 3 becomes smaller when the rotation angle of the movable side front block 3 is smaller than a predetermined angle, and biases the movable side front block 3 to rotate in the upward flipping direction in which the rotation angle of the movable side front block 3 becomes larger when the rotation angle of the movable side front block 3 becomes larger than the predetermined angle.
[0168] In this embodiment, considering the housing space and the rapid level of load increase and decrease, a link spring 51 having a wire diameter of 0.45 mm, a winding diameter of 4 mm, and a natural length of 15 mm is used. Fig.12 ) and release state ( Fig.13 ), the link spring 51 is extended by about 2.3 mm from its natural length. The link spring 51 gradually extends as the movable side front block 3 rotates, and Fig.14 In the state shown, the extension of the link spring 51 is approximately 10 mm. Fig.14The state shown is the state in which the link spring 51 is stretched to the maximum in a series of rotation operations. In other words, the maximum stretch of the link spring 51 is about 10 mm. Thereafter, the link spring 51 gradually contracts, and in the upwardly turned state, the stretch of the link spring 51 is about 5 mm ( Fig.15 ).
[0169] In addition, in the flip-down state ( Fig.12 ) and release state ( Fig.13 ), the spring load (tensile load) of the link spring 51 is about 2N (about 4N for two link springs). Fig.14 ), the spring load is about 6N (two connecting rod springs are about 12N). Fig.15 ) under the condition that the spring load of the connecting rod spring 51 (housing holding load) is about 3.5N (two connecting rod springs are about 7N).
[0170] From the viewpoint of pulling operation, natural operation, and sufficient holding force, it is desirable to set the spring load in the corresponding state to a value within about ±20% of the above value. In this case, the maximum value of the load of the link spring 51 in the rotation operation is 4.8N or more and 7.2N or less. In addition, the maximum value of the load of the link spring 51 in the downward flipped state is 1.6N or more and 2.4N or less. In addition, the maximum value of the load of the link spring 51 in the upward flipped state is 2.8N or more and 4.2N or less. In these cases, the elongation of the link spring 51 also becomes a value within about ±20% of the above value.
[0171] In this article, when the connecting rod spring 51 is stretched to the maximum ( Fig.14 ), the rotation angle of the movable side front block 3 corresponds to the predetermined angle. In other words, the movable side front block 3 is Fig.14 The state in which the movable side front block 3 is farther away from the fixed side front block 2 is a state in which the rotation angle is greater than the predetermined angle. Fig.14 The state closer to the fixed-side front block 2 is a state in which the rotation angle is smaller than a predetermined angle.
[0172] The movable side front block 3 operates in the direction in which the link spring 51 contracts. For example, when the rotation angle is greater than the predetermined angle and the rotation angle further increases (approaches the maximum rotation angle), the link spring 51 contracts more. On the contrary, when the rotation angle becomes smaller (approaches the predetermined angle), the link spring 51 extends more. Therefore, when the rotation angle is greater than the predetermined angle, the movable side front block 3 further operates in the direction in which the rotation angle increases. In other words, when the movable side front block 3 is greater than the predetermined angle, the link spring 51 contracts more. Fig.14 When the movable side front block 3 is further away from the fixed side front block 2, the movable side front block 3 rotates in the upward flipping direction, so that the state of the head mounted display 1 approaches the upward flipping state ( Fig.15 ).
[0173] On the other hand, when the rotation angle is less than the predetermined angle and the rotation angle further decreases (the rotation angle approaches 0 degrees), the link spring 51 contracts more. On the contrary, when the rotation angle becomes larger (approaches the predetermined angle), the link spring 51 extends more. Fig.14 When the movable side front block 3 is closer to the fixed side front block 2, the movable side front block 3 rotates in the downward flipping direction, so that the state of the head mounted display 1 is close to the downward flipping state ( Fig.12 ).
[0174] [Location of the linkage block]
[0175] In the present embodiment, in the basic use state, the link mechanism block 5 is provided in the area of each of the fixed side front block 2 and the movable side front block 3 on the user's face side. Fig.12 As shown in FIG. 1A , in the basic use state (flipped down state), an internal space 60 surrounded by the user's face, the fixed side front block 2, and the movable side front block 3 is formed. The internal space 60 is an area on the user's face side. Meanwhile, the space outside the head mounted display 1 is an area on the non-user face side. The link mechanism block 5 is arranged in the internal space 60.
[0176] So far, in the head mounted display 1 according to the present embodiment, the movable side front block 3 is fixed to the fixed side front block 2 by the locking claw 31. Furthermore, when a predetermined operation is performed by the user, the fixing of the movable side front block 3 with respect to the fixed side front block 2 is released. Therefore, user convenience can be improved.
[0177] Fig.17 is a schematic diagram showing a head mounted display according to a comparative example.
[0178] Fig.17 'A' shows a head mounted display 63 including a ring-shaped attachment block as a comparative example. Fig.17 “B” shows a goggle-type head-mounted display 64 as a comparative example.
[0179] The head mounted display 63 includes a pad 65 that contacts the forehead and a pad 66 that contacts the back of the head. A front block 67 including a display is connected at the lower part of the pad 65, and the front block 67 can be flipped upward ( Fig.17 "A" on the right) or flipped down ( Fig.17 (left image of "A").
[0180] The head mounted display 64 is a goggle type head mounted display and includes a front block 68 including a pad in contact with the periphery of the eyes and a display and a pad 69 in contact with the back of the head. In the front block 68, the pad in contact with the periphery of the eyes is configured to surround the display.
[0181] Since the front block 68 is constantly subjected to the load from the head via the pad, in the event of an attempt to flip the front block 68 upward ( Fig.17 ), the head mounted display 64 cannot be kept attached to the head. In other words, the problem that the front block 68 cannot be turned up occurs.
[0182] However, the goggle type head mounted display 64 is smaller and lighter than the head mounted display 63 including the ring-shaped attachment block, and the goggle type is advantageous in this respect.
[0183] The head mounted display 1 according to the present technology is a goggle type head mounted display 1 in which the movable side front block 3 can be flipped up. Therefore, the advantage of being able to flip up and the advantage of a compact and lightweight goggle type head mounted display are achieved at the same time.
[0184] In the present technology, the fixing of the movable-side front block 3 relative to the fixed-side front block 2 is released by the operation of moving the lower case 20 relative to the lower block 18. Therefore, the user can easily perform the upward turning by the sliding operation.
[0185] In the present technology, the latch of the lock claw 31 relative to the fixed-side front block 2 is released by the operation of moving the lower case 20 relative to the lower block 18. Therefore, the movable-side front block 3 can be stably fixed to the fixed-side front block 2.
[0186] In the present technology, the movable side front block 3 is divided into the lower pad 18 and the lower case 20. Therefore, the head mounted display 1 capable of a sliding operation can be realized.
[0187] In the present technology, the lower housing 20 is movably connected to the lower pad 18 via the slide spring 24. Therefore, the lower housing 20 and the lower pad 18 are stably connected. In addition, the lower housing 20 and the lower pad 18 can be turned up in an integrated manner.
[0188] In the present technology, the locking claw 31 is pressed by the claw pressing rib 38 so that the locking claw 31 rotates in the direction of releasing the latch of the locking claw 31. Therefore, release of the fixing of the movable side front block 3 according to the sliding operation is stably achieved, and accidental release of the fixing is prevented from occurring.
[0189] In the present technology, the movable side front block 3 is rotatably connected to the fixed side front block 2 through the link mechanism block 5. Therefore, the flip-up operation and the flip-down operation are stably performed.
[0190] In the present technology, the link mechanism block 5 is provided in a region of each of the fixed-side front block 2 and the movable-side front block 3 on the user's face side.

[0192] A head mounted display 72 according to the comparative example includes a connection mechanism 73 that rotationally connects the fixed-side front block 2 and the movable-side front block 3 .
[0193] exist Fig.18 In the example shown in "A" of FIG. 7 , the connection mechanism 73 is provided inside the head mounted display 72. However, in this case, since the fixed side front block 2 and the movable side front block 3 abut on the upper side of the connection mechanism 73, the abutting portion hinders the start of the upward flipping. In order to avoid this problem, a method of providing a gap between the abutting portions can be conceived, but this impairs the design of the head mounted display 72.
[0194] Alternatively, if Fig.18 As shown in "B" of FIG. 7 , a method of providing the connection mechanism 73 outside the head mounted display 72 is also conceivable, but this leads to a problem that the size of the head mounted display 72 becomes large and the designability is impaired.
[0195] In the present technology, the link mechanism block 5 is provided inside the head mounted display 1. Since the upper link 48 and the lower link 49 have different lengths, Figures 12 to 15 As shown, the front block 3 on the movable side moves toward the positive side of the Z axis ( Figures 12 to 15 At the same time as the left side of the head mounted display is pushed out, the upward flipping operation starts. Therefore, the abutting portion does not hinder the start of the upward flipping. Therefore, the mechanism for connection can be provided without providing a gap between the abutting portions, and thus a compact head mounted display 1 with high designability is realized.
[0196] In the present technology, when the rotation angle of the movable side front block 3 is less than a predetermined angle, the link spring 51 biases the movable side front block 3 to rotate in the downward flipping direction. In addition, when the rotation angle is greater than a predetermined angle, the movable side front block 3 is biased to rotate in the upward flipping direction.
[0197] For example, when the user flips the movable side front block 3 upward to a state close to the maximum rotation angle, the movable side front block 3 is maintained at the position of the maximum rotation angle even when the user releases his / her hand from the movable side front block 3. In other words, the user can, for example, check a peripheral view or perform a task while releasing his / her hand from the movable side front block 3 during flipping upward.
[0198] In addition, when the rotation angle is less than a predetermined angle, the movable side front block 3 is operated toward the flip-down state. In other words, the flip-down operation can be performed without applying a large force. In this way, the convenience of the head mounted display 1 is improved.
[0199] In the present technology, the link spring 51 is configured so that the maximum value of the load in the rotating operation is 4.8 N or more and 7.2 N or less, the maximum value of the load in the flip-down state is 1.6 N or more and 2.4 N or less, and the maximum value of the load in the flip-up state is 2.8 N or more and 4.2 N or less. Therefore, the movable side front block 3 can be stably biased.
[0200] In the present technology, the fixed side front block 2 is attached to the user's forehead via the upper pad 9. In addition, the movable side front block 3 is attached to the user's cheek via the lower pad 29. Therefore, the load on the user's forehead and cheek when wearing the head mounted display 1 can be reduced, and thus the sense of fit can be enhanced.
[0201] In the present technology, the attachment portion 12 for attaching the belt 14 is provided in the fixed-side front block 2. Therefore, the belt 14 can be stably attached.
[0202] In the present technology, the display 4 is held by the movable-side front block 3. Therefore, a situation in which the display 4 is unintentionally moved due to vibration or the like is prevented from occurring.
[0203] <Other Implementation Methods>
[0204] The present technology is not limited to the above-described embodiments, and various other embodiments can be implemented.
[0205] [Position of upper pad]
[0206] Fig.19 A schematic diagram showing the arrangement position of the upper pad 9.
[0207] Fig.19 The "A" shows the Figure 1 The head mounted display 1 similarly has the protruding upper pad 9. In addition, the longitudinal width a of the upper pad 9 and the longitudinal width b of the head mounted display 1 as a whole are indicated by arrows. Fig.19 "B" shows the head mounted display 1 in which the upper pad 9 does not protrude. In addition, the longitudinal width c of the upper pad 9 and the longitudinal width d of the head mounted display 1 as a whole are indicated by arrows.
[0208] Fig.19The head mounted display 1 shown in "B" includes a planar upper surface 76 positioned on the upper side in the basic use state. In the present embodiment, when the head mounted display 1 is viewed from above, the upper surface 76 is the upper surface of the upper shell 8 or the upper surface of the lower shell 20 near the center when the head mounted display 1 is viewed from above.
[0209] Note that the case where the upper surface 76 is substantially planar is also included in the case where the upper surface 76 is planar. Fig.19 In the example shown in "B" of FIG. 1 , the upper surface 76 is more or less inclined, but in this case, it can also be said that the upper surface 76 is planar. Of course, the case where the upper surface 76 is completely planar is also included in the case where the upper surface 76 is planar.
[0210] exist Fig.19 In the example shown in "B" of FIG. 1 , the upper pad 9 is configured not to protrude from the upper surface 76. Specifically, the position of the upper end of the upper pad 9 and the position of the upper end of the upper surface 76 are substantially at the same position in the up-down direction. In other words, the upper pad 9 does not protrude upward relative to the upper surface 76.
[0211] On the other hand, Fig.19 In the example shown in "A", the upper shell 8 abuts against the upward protrusion of the upper pad 9, so that the head mounted display 1 does not have a planar upper surface. In addition, even when it is assumed that the head mounted display 1 has a planar upper surface, the upper pad 9 protrudes from the upper surface.
[0212] Fig.19 The vertical width d of the entire head mounted display 1 shown in “B” is less than Fig.19 The vertical width b of the entire head mounted display 1 is shown in “A”. Specifically, Fig.19 In "B", the protrusion of the upper pad 9 is eliminated, and the longitudinal width d is reduced by that amount. Therefore, the head mounted display 1 can be miniaturized, and the designability is improved.
[0213] In addition, Fig.19 In the example shown in "B" of FIG. 1 , the longitudinal width c of the upper pad 9 is appropriately set so as not to reduce the attachment stability of the head mounted display 1 during the upward flipping. Specifically, the longitudinal width c is set to a value of 20 mm or more. There may be a case where the attachment stability is more or less reduced by adopting a structure in which the upper pad 9 does not protrude, but by ensuring the longitudinal width c in this way, the reduction in attachment stability can be suppressed.
[0214] [Push button / slide switch]
[0215] Fig. 20 is a schematic diagram showing the head mounted display 1 including buttons.
[0216] In the present embodiment, the head mounted display 1 includes a button 79. The button 79 is provided on the front surface on the lower side of the lower housing 20.
[0217] The button 79 is an operating element for releasing the fixing of the movable side front block 3 relative to the fixed side front block 2. In the present embodiment, the operation of the button 79 is included in the predetermined operation. In other words, when the user presses the button 79, for example, the locking claw 31 operates to release the latch. Therefore, the fixing of the movable side front block 3 is released.
[0218] Therefore, for example, the user can perform a flip-up operation without performing a sliding operation of the movable side front block 3. In other words, there is no need to provide a split structure (lower pad 18 and lower case 20) of the movable side front block 3, and thus miniaturization, lightness, and cost reduction of the head mounted display 1 can be achieved.
[0219] Button 79 corresponds to an embodiment of an operating element according to the present technology. Of course, the specific type of the operating element is not limited. For example, a sliding switch can be set as the operating element. In this case, the predetermined operation is an operation to slide the sliding switch. In addition, the specific structure including the type of the operating element, the position where the operating element is set, etc. is not limited.
[0220] [Light-shielding cover]
[0221] Fig.21 are schematic diagrams each showing a configuration example of a light shielding cover. Fig.21 The "A" shows the Figure 1 A head mounted display 1 similar to the above includes a lower pad 29 . Fig.21 “B” shows the head mounted display 1 including the light shielding cover 82 .
[0222] In this embodiment, the shading cover 82 is in contact with the user's cheek so that the user's cheek does not bear the load. Fig.21 The upper pad 9 is placed at a position similar to the position of the lower pad 29 shown in "A". When the head mounted display 1 is worn, the upper pad 9 receives a load from the user's forehead, but the light shielding cover 82 does not receive a load from the user's cheek. Note that a state in which the light shielding cover 82 receives a load from the user's cheek to a greater or lesser extent is also included in a state in which no load is received.
[0223] The light traveling from the lower side of the head mounted display 1 is blocked by the light shielding cover 82. Fig.21 In the head mounted display 1 shown in “B”, Fig.21 Similar to the head mounted display 1 including the lower pad 29 shown in “A”, excessive light from the outside does not enter the internal space 60, and the sense of immersion when watching a video is maintained.
[0224] Furthermore, in the present embodiment, the head mounted display 1 includes a fixing structure 83 for removably fixing the movable side front block 3 to the fixed side front block 2. For example, the fixing structure 83 is provided at the abutment portion of the fixed side front block 2 and the movable side front block 3 (when the locking claw 31 is latched in the Fig.21 The fixing structure 83 is composed of two structures including a click mountain formed on the fixed side front block 2 and a groove catching shape formed on the movable side front block 3, for example.
[0225] Therefore, the movable side front block 3 is removably fixed to the fixed side front block 2. In other words, it is easy to release the fixation of the fixed side front block 2 with a small force.
[0226] Since the light shielding cover 82 is configured not to bear the load from the user's cheek, the movable side front block 3 will not bear the load via the light shielding cover 82. Therefore, there is no need for a mechanism for bearing the load such as the locking claw 31, and only a simple fixing structure 83 for positioning is required. Therefore, miniaturization and weight reduction of the head mounted display 1 are possible.
[0227] For example, the light shielding cover 82 is formed to have a thickness of about 1 mm, and a silicon material or the like is used as the material. Of course, the specific configuration of the light shielding cover 82 including the material, shape, etc. is not limited. The specific configuration of the fixing structure 83 is also not limited. The light shielding cover 82 corresponds to an embodiment of the light shielding member according to the present technology.
[0228] [Single axis rotation axis]
[0229] In the present embodiment, the head mounted display 1 includes a shaft member 86 that rotatably connects the movable side front block 3 and the fixed side front block 2. The shaft member 86 is composed of a single axis rotation shaft, and as shown in FIG. Fig.18 As shown in "A" of FIG. 1 , for example, while a gap is provided between the abutment portions at the upper portions of the fixed side front block 2 and the movable side front block 3, the shaft member 86 is provided inside the fixed side front block 2 and the movable side front block 3. Alternatively, as Fig.18 As shown in “B” of FIG. 8 , the shaft member 86 is provided outside (above) the fixed-side front block 2 and the movable-side front block 3 .
[0230] Therefore, the structure of the head mounted display 1 is simpler than that in the case where the link mechanism block 5 is provided, and thus the manufacturing cost can be suppressed. The specific configuration, the arrangement position, etc. of the shaft member 86 are not limited.
[0231] [Torque hinge]
[0232] In the present embodiment, the link mechanism block 5 includes a torque hinge. Specifically, for example, the torque hinge is provided in at least one of the four contact portions (bearing portions) between the upper links 48, 49 and the shaft 50. Alternatively, the torque hinge may be provided in all four bearing portions.
[0233] In this case, a force is applied to the movable side front block 3 from the torque hinge to fix the movable side front block 3. In other words, when the user releases the hand from the movable side front block 3 in the flip-up operation, the movable side front block 3 stops at a position where the hand is released without being biased in the flip-up direction or the flip-down direction.
[0234] Therefore, there is no need to provide the link spring 51 for biasing the movable-side front block 3. Therefore, the head-mounted display 1 can be miniaturized.
[0235] Note that when the shaft member 86 is provided, the shaft member 86 may include a torque hinge. Other than these, the specific configuration of the torque hinge is not limited. The torque hinge corresponds to an embodiment of the hinge mechanism according to the present technology.
[0236] [Structure of the bottom pad]
[0237] The lower pad 29 may be configured to contact the user's chin, etc. In addition, the lower pad 29 may be formed of a single member, rather than being separated to both sides. In addition to these, the specific configuration of the lower pad 29 is not limited.
[0238] [Feature comparison between structures]
[0239] Fig. 22 : is a table showing the features of each structure of the head mounted display 1 .
[0240] Fig.23 is a schematic diagram showing a head mounted display 89 according to a comparative example.
[0241] Fig.23 The head mounted display 89 shown includes a pad that contacts the user's forehead and a pad that contacts the back of the head. In addition, the front block is connected to the lower part of the pad that contacts the forehead. In other words, Fig.17 Similar to the head mounted display 63 shown in "A" of FIG. 8 , the head mounted display 89 is a head mounted display including a ring-shaped attachment block. A gap for flipping up operation is provided between the pad that contacts the forehead and the front block.
