Description

  The present technology relates to a head mounted display that is used by being mounted on a user's head.

  2. Description of the Related Art A head mounted display (hereinafter also referred to as an HMD) configured to present an image to an individual user by a display mounted on the user's head and placed in front of the eyes is known. The HMD needs to fix the position of the display surface with respect to the left and right eyes of the user in order to prevent image blurring and defocusing. Therefore, as described in Patent Document 1, a configuration is known in which the display unit is supported in front of the user's eyes by two bands that can be mounted on the back of the user's head.

JP 2012-186660 A

  However, the HMD configured as described above is inconvenient because it is necessary to adjust the length of the band every time it is attached or detached. In addition, when it is not worn, it must be removed from the head and carried, and the convenience of carrying it could not be ensured.

In view of the circumstances as described above, an object of the present technology is to provide an HMD that is easy to attach and detach and excellent in portability.
Note that the effects described here are not necessarily limited, and may be any of the effects described in the present disclosure.

In order to achieve the above object, a head mounted display according to an embodiment of the present technology includes a first display unit, a second display unit, and a support unit.
The first display unit includes a first display board capable of presenting an image to one eye of the user, and a first connecting unit.
The second display unit includes a second display panel capable of presenting an image to the other eye of the user, and a second connection unit detachably connected to the first connection unit.
The support unit connects the first display unit and the second display unit, and is attached to the user's head.

  According to the head mounted display, the first and second connecting portions can be divided between the first and second display portions. Thereby, attachment / detachment can be made easy. Moreover, it can be set as the structure excellent also in portability by hanging a support part from a neck at the time of a division | segmentation.

The first connecting portion has a first surface,
The second connecting portion may have a second surface that faces the first surface in the first axial direction and holds the first surface by suction.
Thereby, the 1st and 2nd surfaces can be adsorb | sucked at the time of a connection, and the connection attitude | position of a 1st and 2nd connection part can be defined.

In addition, the first connecting portion has a first engaging portion provided at an end facing the second connecting portion,
The second connecting portion may include a second engaging portion that engages with the first engaging portion at a predetermined connecting position with the first connecting portion.
Thereby, the connection attitude | position of a 1st and 2nd connection part can be defined in a predetermined | prescribed connection position. Therefore, it is possible to prevent a user's congestion shift at the time of wearing.

The second connecting portion is provided on a peripheral edge of the second surface, and the second engaging portion extends along the second axial direction perpendicular to the first axial direction. You may further have a guide part to guide to.
Thereby, connection between the 1st and 2nd connection parts can be performed smoothly.

Specifically, the first engagement portion may include a shaft portion having an axial center in a third axial direction orthogonal to the first axial direction and the second axial direction.
Thereby, it becomes possible to isolate | separate a 1st engaging part and a 2nd engaging part because a 1st engaging part rotates around a shaft part.

The second engaging portion may include a restricting portion that faces the first axial direction across the second surface and the shaft portion.
Accordingly, the first and second connecting portions can be easily removed by rotating the first engaging portion around the shaft portion. On the other hand, when a force that rotates the shaft portion around the other end portion acts, the first and second engaging portions are locked. Therefore, it is possible to provide a configuration that gives directionality to the attachment / detachment and satisfies both ease of attachment / detachment and difficulty of detachment.

The first connecting portion has a first permanent magnet,
The second connecting portion may include a second permanent magnet that is eccentrically disposed in the second axial direction with respect to the first permanent magnet.
As a result, the first and second permanent magnets can exert an attractive force in both the first axial direction and the second axial direction.

The first display section and the second display section are orthogonal to the third axial direction and in a fourth axial direction that is not parallel to the first axial direction and the second axial direction. They may be arranged side by side.
Thereby, the first surface and the second surface can be configured to be non-parallel to the fourth axial direction in which the first and second display units are arranged. Therefore, compared with the case where these are parallel, the distance of the axial part and other end part which were provided in the one end part of the 1st connection part can be comprised long, and a bigger rotational moment can be made to act. it can. From this, it becomes possible to easily generate a rotational moment that overcomes the attractive force of the first and second surfaces.

  As described above, according to the present technology, it is possible to provide an HMD that is easy to attach and detach and excellent in portability.

Similarly, the second surface 221 is also formed on the second frame 220 and is disposed around a second cover 225 described later. In the present embodiment, the first and second surfaces 121 and 221 are attracted by a magnetic force acting between a first permanent magnet 122 and a second permanent magnet 222 described later.

  FIG. 5 is an exploded perspective view of the first connecting portion 12. The first connecting portion 12 includes a first frame 120, a first permanent magnet 122, a yoke 123, a screw 123 a, a first cover 124, and a second cover 125. The yoke 123, the first permanent magnet 122, the first cover 124, and the second cover 125 are stacked in the recess of the first frame 120 in this order. A first surface 121 is formed on the second cover 125.

  The first frame 120 supports the yoke 123 and the first permanent magnet 122. The first frame 120 has, for example, a recess in which a screw hole is formed, and the yoke 123 is fixed in the recess by a screw 123a. The first frame 120 may be made of a nonmagnetic material, for example.

  The first permanent magnet 122 includes, for example, a magnet 122a and a magnet 122b. The two magnets 122a and 122b are disposed on the yoke 123 along the Y-axis direction with the surfaces having different polarities facing outward. The yoke 123 is composed of a soft iron plate.

  FIG. 6 is an exploded perspective view of the second connecting portion 22. Similar to the first connecting portion 12, the second connecting portion 22 includes a second frame 220, a second permanent magnet 222, a yoke 223, a screw 223a, a first cover 224, and a second cover. Cover 225 and a front cover 229. The yoke 223, the magnet (second magnetic member) 222, the first cover 224, and the second cover 225 are stacked in the recess of the second frame 220 in this order. A second surface 221 is formed on the second cover 225.

  The second frame 220 supports the yoke 223 and the second permanent magnet 222. The second frame 220 has, for example, a recess in which a screw hole is formed, and the yoke 223 is fixed in the recess by a screw 223a. The second frame 220 may be made of a nonmagnetic material, for example.

  The second permanent magnet 222 includes, for example, a magnet 222a and a magnet 222b. The magnet 222a and the magnet 222b are disposed on the yoke 223 along the Y-axis direction. The two magnets 222 a and 222 b are arranged with their polarities adjusted so that they can be attracted to the two magnets 122 a and 122 b of the first permanent magnet 122. Since the first and second permanent magnets 122 and 222 each have two magnets, the attractive force between the first and second surfaces 121 and 221 can be further increased. The yoke 223 is composed of a soft iron plate.

  The first cover 224 is disposed on the magnets 222a and 222b, and may be made of, for example, an adhesive paper for bonding the magnets 222a and 222b and the second cover 225. The second cover 225 functions as a magnet cover made of a nonmagnetic material such as SUS, and is disposed on the first cover 224. The second cover 225 can prevent the magnets 222a and 222b from being damaged. The shape of the second cover 225 may be a shape in which the edge of the flat surface is bent, for example. This prevents the end surface of the second cover 225 from coming into contact with the first engaging portion 126 during a connecting operation, which will be described later, and enables a smooth connecting operation.

  The front cover 228 is attached to the opposite side of the second frame 220 to the side where the magnets 222a and 222b are disposed. A method for attaching the front cover 229 to the second frame 220 is not particularly limited. For example, the front cover 229 may be adhered to the second frame 220 by attaching an adhesive paper to the back surface of the front cover 229. The front cover 229 is disposed between the first and second display panels 11 and 21 at the connection position (see FIG. 1).

  The 1st and 2nd connection parts 12 and 22 comprised as mentioned above are mutually attracted and connected by the 1st and 2nd permanent magnets 122 and 222. In the following description, the positions of the first and second connecting portions 12 and 22 in the connected state are referred to as “predetermined connecting positions” or simply “connecting positions”. Hereinafter, the structure regarding the connection of the 1st and 2nd connection parts 12 and 22 is demonstrated.

  FIG. 7 is a cross-sectional view of the main part at the connecting position of the first and second connecting parts 12 and 22. The 2221 is opposed to the first surface 121 in the z-axis direction at a predetermined coupling position, and is arranged closely. Thereby, for example, a gap of about 0.2 mm may be formed between the second covers 125 and 225. The first and second surfaces 121 and 221 are configured as surfaces that are not parallel to the XY plane. Hereinafter, the normal direction of the first and second surfaces 121 and 221 is the z-axis direction (second axial direction), the direction parallel to the Y-axis direction is the y-axis direction (third axial direction), and the z-axis. A direction orthogonal to the direction and the y-axis direction is taken as an x-axis direction (third axial direction). That is, the X-axis direction is a direction orthogonal to the y-axis direction and non-parallel to the x-axis direction and the z-axis direction.

  A suction force in the z-axis direction acts between the first and second surfaces 121 and 221. Thereby, the position between the 1st and 2nd connection parts 12 and 22 in az axis direction can be defined. Further, since the first and second surfaces 121 and 221 are adsorbed, rotation around the x-axis and the y-axis between the first and second connecting portions 12 and 22 can be prevented. In this embodiment, if each side of the first and second surfaces 121 and 221 has a length of about 10 mm or more, a sufficient area for maintaining the connection posture can be secured.

  As shown in FIG. 7, the second permanent magnet 222 is arranged eccentrically with respect to the first permanent magnet 122 in the x-axis direction at the connection position. Accordingly, the second permanent magnet 222 exerts an attractive force having not only the z-axis direction component but also the x-axis direction component on the first permanent magnet 122 (see the arrow in FIG. 7). Specifically, an attractive force including about 10 N components in the z-axis direction and about 4 N components in the x-axis direction can be applied between the first and second permanent magnets 122 and 222. Therefore, the positional accuracy in the x-axis direction between the first and second connecting portions 12 and 22 can be increased.

  FIG. 8 is a perspective view of the first and second connecting portions 12 and 22 as viewed from the back side, showing a mode at the connecting position. The first connecting part 12 has a first engaging part 126 and an edge part 127. The second connecting part 22 includes a second engaging part 226 and a guide part 227.

  As shown in FIGS. 7 and 8, the first engaging portion 126 is provided at an end portion (left end portion) that faces the second connecting portion 22 in the x-axis direction. The first engaging portion 126 has a shaft portion 126a having an axis in the y-axis direction. The shaft portion 126a may include two shaft portions arranged along the y-axis direction, and each of the two shaft portions may engage with the second engaging portion 226 (not shown). As a result, it is possible to position the second engagement portion 226 at two points, and it is possible to maintain the connection posture with higher accuracy.

  As shown in FIGS. 7 and 8, the second engagement portion 226 engages with the first engagement portion 126 at a predetermined coupling position. The second engaging portion 226 has a tip portion 226a and a restricting portion 226b. The tip end portion 226a is formed so as to be connected to the second surface 221 and faces the shaft portion 126a in the x-axis direction.

  The restricting portion 226b faces the z-axis direction across the second surface 221 and the shaft portion 126a. In the present embodiment, the restricting portion 226b is formed as a tapered surface whose distance from the second surface 221 increases as the distance from the distal end portion 226a increases in the x-axis direction. The restricting portion 226b is configured to be able to contact the first engaging portion 126 at the coupling position. Thereby, the position in the x-axis direction between the first and second engaging portions 126 and 226 is defined.

  The edge part 127 is provided in the periphery of the 1st surface 121, as shown in FIG. The edge portion 127 includes an upper edge portion 127 a formed at the upper edge of the first frame 120 and a lower edge portion 127 b formed along the lower edge of the first frame 120. The upper edge portion 127a and the lower edge portion 127b are opposed to each other in the Y-axis direction and are formed along the x-axis direction. The width between the upper edge portion 127a and the lower edge portion 127b is set to about 17 mm, for example.

  As shown in FIG. 4, the guide part 227 is provided on the periphery of the second surface 221. The guide portion 227 is configured to be engageable with the edge portion 127 and guides the first engagement portion 126 to the second engagement portion 226 along the x-axis direction.

  The guide part 227 includes an upper guide part 227 a formed on the upper edge of the second frame 220 and a lower guide part 227 b formed on the lower edge of the second frame 220. The upper guide portion 227a and the lower guide portion 227b are opposed to each other in the Y-axis direction and are formed along the x-axis direction. The upper guide portion 227a engages with the upper edge portion 127a, and the lower guide portion 227b engages with the lower edge portion 227b. Although the structure of the upper guide part 227a and the lower guide part 227b is not specifically limited, For example, it is comprised in the step shape which can be engaged with each of the upper edge part 127a and the lower edge part 127b.

  By connecting the first and second connecting portions 12 and 22 configured as described above to each other, the connecting posture of the first and second connecting portions 12 and 22 is accurately maintained. Specifically, the connection position in the x-axis direction is determined by the first and second engagement portions 126 and 226, and the rotation about the z-axis between the first and second connection portions 12 and 22 is performed. Is prevented. When the guide part 227 engages with the edge part 127, the connection position in the y-axis direction is determined. Further, the first and second surfaces 121 and 221 are adsorbed in the z-axis direction, so that a connection position in the z-axis direction is defined, and x between the first and second connection parts 12 and 22 is determined. Rotation around the axis and y axis is prevented.

  As described above, the first and second connecting portions 12 and 22 can define the connecting position with respect to each of the three axial directions of the x-axis, y-axis, and z-axis, and therefore, the three in the X-axis, y-axis, and Z-axis directions. Similarly, the connection position can be determined for each axial direction. Specifically, rotation about the X axis can be suppressed to about 3 minutes or less, rotation about the Y axis can be suppressed to about 4.6 minutes or less, and rotation about the Z axis can be suppressed to about 17 minutes or less.

  Here, since the first and second display boards 11 and 21 emit desired image light to the user's eyes, a convergence shift occurs when the connection position shifts or rotates. According to this embodiment, since the connection posture is accurately maintained, it is possible to prevent problems such as congestion deviation.

  Moreover, the 1st and 2nd connection parts 12 and 22 can be attached or detached easily. Hereinafter, the operation of the first and second connecting portions 12 and 22 accompanying attachment and detachment will be described.

  FIG. 9 is a schematic cross-sectional view showing the configuration before and after the first and second connecting portions 12 and 22 are attached / detached, where A is before connection (when divided), and B is a mode at the connection position.

  When the first and second connection portions 12 and 22 are brought closer to the state before the connection shown in FIG. 9A, the first and second connection portions 12 are caused by the attractive force generated between the first and second permanent magnets 122 and 222. , 22 are attracted. Further, as shown in FIG. 3, the first frame 120 has a tapered portion 128, and as shown in FIG. 4, the guide portion 227 has a tapered portion 228. Thereby, even when the user pulls the first and second connecting portions 12 and 22 by groping, the edge portion 127 can be easily engaged with the guide portion 227.

  The guide portion 227 and the edge portion 127 are formed along the x-axis direction as described above. Thereby, the guide part 227 slides the edge part 127 along the x-axis direction, and guides the first engaging part 126 to the second engaging part 226 (see FIG. 8). Then, as the first engaging portion 126 engages with the second engaging portion 226, the first and second connecting portions 12, 22 are connected at the connecting position as shown in FIG. 9B. . The guide portion 227 can guide the first connecting portion 12 to the connecting position smoothly and reliably.

Is configured to be maintained. Hereinafter, the split operation for releasing the engagement and the lock mechanism for maintaining the connected state will be described.

  FIG. 10 is a schematic diagram for explaining the division operation of the first and second display units 10 and 20, wherein A is a cross-sectional view of a mode of wearing on the user's head, and B is the first and second. It is principal part sectional drawing of the connection parts 12 and 22 of. 10A and the following FIG. 11A, the configurations of the ear hooking portion 32 and the nose pad 129 are omitted, and the configurations of the first and second connecting portions 12 and 22 are shown exaggerated from the actual ones. .

  In addition, in FIG. 10, although the band member 31 of the support part 30 is directly mounted | worn with the head, it is not restricted to this. The band member 31 of the support portion 30 may be larger than the head portion and disposed around the head portion, and may be attached to the head portion by the ear hook portion 32. By doing in this way, the length adjustment of the band member 31 becomes unnecessary. Moreover, you may make it the ear hook part 32 improve a feeling of fitting as a shape which wraps around the back of an ear. Moreover, you may make it reduce the side pressure to the head of the ear hook part 32 at this time. Furthermore, the position of the ear hook 32 may be adjusted with respect to the band member 31. Thereby, a feeling of fitting can be improved further.

  As shown by an arrow a in FIG. 10A, for example, the user operates the front cover 229 to open the vicinity forward in the Z-axis direction (see arrow a in FIG. 10A).

  As a result, a forward force in the Z-axis direction is applied to the left end portion of the second connecting portion 22 at the connecting position, and each of the first and second connecting portions 12 and 22 has a Y-axis around the shaft portion 126a. The opposite rotational moment acts. That is, the left end portion of the second connecting portion 22 tends to rotate forward in the Z-axis direction (see arrow a in FIG. 10B), and the left end portion of the first connecting portion 12 tends to rotate backward in the Z-axis direction ( (See arrow b in FIG. 10B). When this rotational moment overcomes the attractive force between the first and second permanent magnets 122 and 222, the first surface 121 is separated from the second surface 221. As a result, the first engaging portion 126 formed at the right end portion of the first connecting portion 12 is rotated forward in the Z-axis direction around the shaft portion 126a, and the first engaging portion 126 is moved to the second engaging portion. The first connecting portion 12 and the second connecting portion 22 are separated from each other with respect to the joining portion 226.

  On the other hand, FIG. 11 is a schematic diagram for explaining a locking mechanism of the first and second display units 10 and 20, wherein A is a cross-sectional view of an aspect mounted on the user's head, and B is the first and FIG. 6 is a cross-sectional view of a main part of second connection parts 12 and 22. As shown by the arrow c in FIG. 11B, a force in a direction that spreads to the left and right is applied to the band member 31 at the time of wearing according to the shape of the user's head. Or when a user tries to adjust the position etc. of the ear hook part 32, the force of the left-right direction shown by the arrow c of FIG. 11B acts similarly. As a result, the first and second display plates 11 and 21 are opened to the left and right, and a force that pushes forward in the Z-axis direction acts. A force forward in the Z-axis direction also acts on the left end portion where the engaging portion 226 is formed (see arrow d in FIGS. 11A and B).

  When a forward force is applied to the right end portion of the first connecting portion 12 and the left end portion of the second connecting portion 22 at the connecting position, the first and second connecting portions 12 and 22 are respectively connected to the shaft. A rotational moment about the Y axis around the portion 226a acts. That is, the left end portion of the first connecting portion 12 tries to rotate forward in the Z-axis direction (see arrow e in FIG. 11B), and the right end portion of the second connecting portion 22 also tries to rotate forward in the Z-axis direction (see FIG. 11). 11B arrow f). As a result, the first engaging portion 126 formed at the right end portion rotates in the Z-axis direction rearward with the rotational moment, but comes into contact with the restricting portion 226b of the second engaging portion 226, The rotation is restricted. As a result, the movements of the first and second connecting portions 12 and 22 are locked, and the connecting posture is maintained.

  Further, various forces act on the band member 31 and the ear hook 32 at the time of wearing, in addition to the force in the direction of opening left and right. Since the band member 31 and the ear hooking portion 32 are relatively far from the shaft portion 226a serving as a fulcrum, a large rotational moment acts on the first and second connecting portions 12 and 22 with these acting points. obtain. According to the present embodiment, the first and second permanent magnets 122 and 222 are arranged at the left end portion far from the shaft portion 226a at the right end portion, and the first and second permanent magnets 122 and 222 have an attractive force. A large permanent magnet is used. As a result, even if a large rotational moment as described above is applied, the rotational moment can be countered by the attracting force, and the connected posture can be maintained.

  In addition, since the first and second surfaces 121 and 221 are arranged non-parallel to the X-axis direction, the shaft portion 126a serving as a fulcrum and the first 126 The distance between the first and second permanent magnets 122 and 222 can be made longer. Thereby, it can be set as the structure which can endure more effectively with respect to a rotational moment.

  As described above, the restriction portion 226b of the second engagement portion 226 allows the first engagement portion 126 to rotate forward in the Z-axis direction around the shaft portion 126a of the first engagement portion 126, while the first engagement portion The rearward rotation of the shaft 126 around the shaft 126a is restricted (see FIGS. 10B and 11B). That is, the restricting portion 226b can easily act on the user's wearing, for example, against a force in the direction of expanding the band member 31 in the left-right direction, and can reliably lock the movement of the first and second engaging portions 126, 226. On the other hand, depending on the operation of opening the first and second connecting portions 12 and 22 forward in the Z-axis direction, the lock can be easily released, and the first and second connecting portions 12 and 22 can be separated. It becomes possible.

  Therefore, according to the present embodiment, it is possible to provide a head-mounted display 100 that can be easily detached by a predetermined operation and can be easily detached and attached during normal wearing or other operations.

  Furthermore, the head mounted display 100 can be carried by dividing the first and second display units 10 and 20 and hanging the band member 31 around the neck. Thereby, it can be set as the structure excellent also in portability.

  In addition, as described above, the head mounted display 100 can maintain the connection posture between the first and second connecting portions 12 and 22, and the positions of the first and second display portions 10 and 20 can be maintained. Can be determined accurately. Therefore, even if the head-mounted display 100 is required to have high optical position accuracy, it is possible to realize a configuration that can be easily attached and detached while satisfying the request.
