Description

[Technical Field]

[0001] The present invention relates to a display device such as a head-mounted display (hereinafter referred to as HMD) as an XR device that enables an XR (Extended Reality / Cross Reality) experience. In particular, the present invention relates to the configuration of a connection mechanism between a display unit and a mounting unit in an HMD. [Background technology]

[0002] Conventional HMDs are known to have a configuration in which the display unit can be swapped between a head-mounted mounting unit and a handheld mounting unit, allowing for usage suited to the user's circumstances. In such a configuration, to simplify the swapping of the display unit and mounting unit, it is desirable to have a configuration in which the swapping can be completed with a simple action of pushing one into the other. In this case, a mechanism is required in which the display unit and mounting unit are released when a release lever is pushed in, so that the display unit and mounting unit do not come loose while the HMD is in use, but can be easily removed when the user intends to swap the mounting unit.

[0003] This is not limited to HMDs, but for example, the PC display disclosed in Patent Document 1 has a mechanism for fastening the display by biasing a locking member with an elastic member and using a disconnection lever to release and remove the display. Also, the PC display disclosed in Patent Document 2 employs a configuration in which the display is fixed to the main body by being attracted and pulled in by a magnet.

[0010] The following examples will exemplarily illustrate embodiments of the present disclosure. However, the configurations disclosed in the following examples, such as the functions, materials, shapes, and relative positions of components, are merely examples of embodiments related to the claims, and are not intended to limit the scope of the claims to the configurations disclosed in these examples. Furthermore, the problems solved by the configurations disclosed in the following examples or the actions or effects obtained from the disclosed configurations are not intended to limit the scope of the claims.

[0011] (First embodiment) First, an HMD (head mounted display) 100, which is a display device according to a first embodiment of the present invention, will be described with reference to Fig. 1. Fig. 1 is a perspective view showing the appearance of the HMD 100 according to the embodiment of the present invention in a state where it is worn on the head of a user.

[0012] The HMD 100 includes a display main body 101 as a display unit, a wearing unit 300, and a connecting mechanism unit 200 as a connecting unit that connects the display main body 101 and the wearing unit 300. The display main body 101 includes a display panel 510 and a display prism 520, which will be described later. The display main body 101 is a main body that can provide the user with an XR experience such as VR (Virtual Reality), AR (Augmented Reality), or MR (Mixed Reality).

[0013] The camera 400 is an imaging means, and is provided with one camera on each side on the front of the display main body 101. It captures the surrounding scenery and enables the generation of a background image for the XR experience. The imaging information of the camera 400, together with the detection information of the orientation detection sensor mounted on the display main body 101, is used to align the CG image superimposed on the surrounding image that serves as the background when the user experiences the XR experience.

[0014] The wearing unit 300 is a wearing means for fixing the display main body 101 in front of the user's eyes by being worn on the head like a headband. Since it is sufficient to fix the display main body 101 in front of the eyes, the specific form of the wearing unit 300 is not limited to this headband form, and it may be, for example, a form worn on the ears like glasses, or a handheld form that can be easily handed over between users. In other words, the part of the user's body to which the wearing unit 300 is fixed is not limited to the head.

[0015] The connecting mechanism unit 200 is a connecting means that connects the display main body 101 and the mounting part 300 so that the display main body 101 is held in front of the user's eyes. The connecting mechanism unit 200 is fixed to the lower end of the mounting part 300 that surrounds the user's head, at a portion corresponding to the forehead of the user's head, and is connected to the display main body 101 so that the display main body 101 is positioned in front of the user's eyes.

[0016] As shown in FIG. 1, in this embodiment, the left-right direction of the product is the X axis, the up-down direction is the Y axis, and the front The rear direction is referred to as the Z axis. 1 and 2, among the various components of the display main body 101, components for the left eye are designated by reference numerals with an L added to the end, and components for the right eye are designated by reference numerals with an R added to the end. The left eye and right eye configurations are symmetrical, and when there is no need to distinguish between the left and right, the L and R in the reference numerals will be omitted.

[0017] FIG. 2 is a horizontal cross-sectional view of a state in which a user is looking into the display main body 101. The display panel 510 is a display means that displays an image for an XR experience such as VR, AR, or MR. Generally, an LCD (Liquid Crystal Display) or an OLED (Organic Light Emitting Diode) is used for the display panel 510. The display prism 520 is an optical element of a display optical system that projects an image displayed on the display panel 510 toward the user's eyes. In this embodiment, the display prism 520 is a free-form prism. The prism holder 530 is a holding member that holds the display panel 510 and the display prism 520. The prism holder 530, the display panel 510, and the display prism 520 move together during IPD adjustment, which will be described later, and are collectively referred to as a display unit 500.

[0018] The camera 400 is an imaging means for capturing an image of the surrounding real world, and is provided with one camera on each side in front of the display main body 101. Another purpose is that the camera 400 can also be used as a position and orientation detection means for detecting feature points such as markers and object edges from the image captured by the camera 400 and acquiring the position and orientation of the display main body 101.

[0019] The control board 410 is a control means that processes images captured by the camera 400, combines them with CG images, and analyzes information detected by the position and orientation detection means to generate an appropriate display image to be displayed on the display panel 510. Incidentally, an imaging means other than the camera 400 may be provided and used as the position and orientation detection means. In this case, since there is no need to be limited to the purpose of acquiring a real image of the surroundings, it is possible to employ a camera with a wide angle of view and a high shutter speed or to arrange it with a long baseline length. Furthermore, a gyro sensor electrically connected to the control board 410 can be provided to enable orientation detection with higher accuracy. Using these means enables highly accurate position and orientation detection and position and orientation detection that can be used in a wide range of environments.

[0020] A cable socket 420 is provided on the side of the display main body 101, and a communication cable 430 is connected to it. The control board 410 may be configured to communicate with another control unit such as an external personal computer or controller via the communication cable 430, so that part of its processing is performed externally. Also, the control board 410 may be configured to receive power from an external source via the communication cable 430. This can be expected to reduce the size of the control board 410 and reduce power consumption.

[0021] The IPD adjustment guide 540 is an adjustment guide member for aligning the position of the display unit 500 with the interpupillary distance (InterPupillary Distance), which generally varies from user to user. This adjustment of the position of the display unit 500 to match the interpupillary distance of the user is called IPD adjustment. While viewing an image displayed on the display panel 510 through the display prism 520, the user moves the display unit 500 in the X-axis direction, which is the interpupillary distance adjustment direction, to a position that provides optimal visibility, by hand or by controlling a drive motor or other means. The exterior casing 105 is an exterior member that holds the above-mentioned components.

[0022] 3 is a schematic cross-sectional view of the connection mechanism unit 200 that connects the display main body 101 and the mounting part 300. FIG. 3 shows the state in which the mounting part 300 is attached to the display main body 101 via the connection mechanism unit 200.

[0023] In this embodiment, the connecting mechanism unit 200 is composed of an attachment portion-side configuration fixed to the display main body 101 and a main body-side configuration fixed to the attachment portion 300. That is, in the connecting mechanism unit 200, the configuration fixed to one of the display main body 101 and the attachment portion 300 and the configuration fixed to the other are connected to each other, thereby connecting the display main body 101 and the attachment portion 300.

[0024] The main body side component fixed to the display main body 101 in the connection mechanism unit 200 is a main body side coupled part 110 as a first coupling part. The mounting part side component fixed to the mounting part 300 in the connection mechanism unit 200 is made up of a main body side coupling part 201 as a movable part, a coupling / release lever 202 as a lever member, and a mounting part side coupling part 210 as a second coupling part.

[0025] The main body side connectable part 110 is disposed as part of the display main body 101 and is a protrusion for attaching the display main body 101 to the connecting mechanism unit 200. The connecting / disconnecting lever 202 is rotatably attached to the main body side connecting part 201 and is configured to be engageable with the main body side connectable part 110. The connecting / disconnecting lever 202 is a member for connecting the display main body 101 to the connecting mechanism unit 200 by engaging with the main body side connectable part 110. In other words, by connecting the display main body 101 to the connecting mechanism unit 200, the display main body 101 is connected to the mounting part 300 via the connecting mechanism unit 200.

[0026] The main body side coupled part 110 has an upright part 1101 extending in the D2 direction from the display main body 101, and a convex part 1102 extending so as to bend from the tip of the upright part 1101 in a direction intersecting the D2 direction. The convex part 1102 has a contact surface 1103 facing the display main body 101 and serving as an engaged part that engages with the coupling / disconnecting lever 202. The coupling / disconnecting lever 202 is attached to be rotatable about a rotation shaft 2021 having a rotation axis that is approximately along the left-right direction (X-axis direction) with respect to the main body side coupling part 201. The coupling / disconnecting lever 202 is provided with a contact surface 2023 serving as an engaging part that can engage with the contact surface 1103 of the main body side coupled part 110, and a release lever part 2024 serving as an operating part for operating the engagement / disengagement between the contact surface 1103 and the contact surface 2023. The coupling / disconnecting lever 202 has a recess that is recessed in a direction intersecting the D2 direction, and when the protrusion 1102 of the main body side coupled part 110 is inserted into this recess in a direction intersecting the D2 direction, the surface of the recess that faces the contacted surface 1103 is the contact surface 2023. The contact surface 2023 and the contacted surface 1103 face each other (abut) in the D2 direction, thereby restricting the coupling / disconnecting lever 202 (main body side coupling part 201) and the main body side coupled part 110 from moving away from each other in the D2 direction.

[0027] The coupling / disengaging lever 202 is configured to be operable to engage / disengage between the contacted surface 1103 and the contact surface 2023 by pressing the release lever portion 2024 in a predetermined operating direction. In this embodiment, the predetermined operating direction is a direction intersecting the D2 direction. When the release lever portion 2024 is pressed in the predetermined operating direction, the posture of the coupling / disengaging lever 202 with respect to the main body side coupling portion 201 changes from an engaged posture (first posture) in which the contact surface 2023 can engage with the contacted surface 1103 to a disengaged posture (second posture) in which the contact surface 2023 does not engage. The engaged posture is a posture in which the contact surface 2023 and the contacted surface 1103 face each other in the D2 direction (they have overlapping portions when viewed in the D2 direction). The disengaged posture is a posture in which the contact surface 2023 and the contacted surface 1103 do not face each other in the D2 direction (they do not have overlapping portions when viewed in the D2 direction).

[0028] The mounting unit side coupling part 210 is a member fixedly disposed on the mounting unit 300 and rotatably holds the main body side coupling part 201. The main body side coupling part 201 rotates around a rotation axis 211 having a rotation axis line approximately along the left-right direction (X-axis direction) with respect to the mounting unit side coupling part 210, thereby The display body 101 is attached so that its relative position with respect to the mounting unit-side coupling part 210 can be changed (displaced). When the coupling / disconnecting lever 202 is engaged with the main body-side coupled part 110, the main body-side coupling part 201 rotates with respect to the mounting unit-side coupling part 210, allowing the display body 101 to move around the rotation axis 211 with respect to the mounting unit 300. Also, by providing an appropriate frictional force to such a rotating part, it is possible to adjust the position of the display body 101 with respect to the mounting unit 300. Furthermore, by using this rotation mechanism, it is possible to switch the positional relationship between the display body 101 and the mounting unit 300 between a first state, which is a used state, and a second state, which is a detached state, which will be described later.

[0029] 4(a) is a schematic diagram showing the configuration of the main body side coupling part 201 and the coupling / disconnecting lever 202 of the coupling mechanism unit 200. The main body side coupling part 201 is provided with a spring 203 as a first biasing means that biases the coupling / disconnecting lever 202 so as to rotate in a rotational direction that changes the posture of the coupling / disconnecting lever 202 from an engaged posture to a disengaged posture. The coupling / disconnecting lever 202 is disposed relative to the main body side coupling part 201 so as to be rotatable about a rotation axis 2021, and a force that rotates clockwise in the figure is constantly applied by the biasing force of the spring 203.

[0030] The connection mechanism unit 200 also has a spring 111 as a second biasing means that applies a biasing force between the main body side coupling part 201 and the display main body 101 to separate them from each other. The spring 111 is interposed between the main body side coupling part 201 and the display main body 101, and biases the main body side coupling part 201 and the display main body 101 so as to separate them from each other in the direction D2. This biasing force brings the contact surface 2023 and the contacted surface 1103 into close contact with each other in the direction D2, and the main body side coupling part 201 is fixed to the main body side joinable part 110, and the display main body 101 is fixed to the mounting part 300 via the connection mechanism unit 200.

[0031] 4(b) is a schematic diagram showing how the body-side coupling part 201 of the coupling mechanism unit 200 is coupled to the body-side coupled part 110 when the display body 101 is attached. When coupling the display body 101 and the mounting part 300, the user, for example, moves the body-side coupled part 110 and the body-side coupling part 201 closer together in the vertical direction (direction D2) in the figure. At this time, the end part (convex part 1102) of the body-side coupled part 110 comes into contact with the inclined surface 2022 that is part of the coupling / release lever 202, and moves closer to the body-side coupling part 201 in a manner that pushes away the coupling / release lever 202. When the connection / disconnection lever 202 is pressed by the end (convex portion 1102) of the main body side coupled portion 110, it receives a pressing force greater than the spring force of the spring 203, and rotates counterclockwise in the figure around the rotation axis 2021 while compressing the spring 203, changing from an engaged position to a disengaged position.

[0032] When the end face of the convex portion 1102 of the main body side coupler part 110 climbs over the inclined surface 2022, the coupling / disconnecting lever 202 rotates clockwise in the figure due to the biasing force of the spring 203, returning from the non-engaged position to the engaged position. As a result, the convex portion 1102 of the main body side coupler part 110 enters the recess of the coupling / disconnecting lever 202, and the contacted surface 1103 of the main body side coupler part 110 faces the contact surface 2023 of the coupling / disconnecting lever 202 in the direction D2 and comes into contact with it. That is, the relative arrangement shown in FIG. 4(a) is reached, and the main body side coupler part 110 and the main body side coupling part 201 are fixed to each other.

[0033] In the state of FIG. 4(a), a spring 111 arranged around the main body side coupled part 110 constantly applies a biasing force in the downward direction in the figure to the display main body 101. This biasing force acts to press the contact surface 1103 of the main body side coupled part 110 against the contact surface 2023 of the coupling / disconnecting lever 202, resulting in a stable coupled state between the main body side coupled part 110 and the main body side coupling part 201. With this mechanism, the user can couple the display main body 101 to the mounting part 300 simply by pushing the display main body 101 in the vertical direction (direction D2) against the coupling mechanism unit 200, and this allows for easy attachment. can be done.

[0034] Here, the convex portion 1102 of the main body side connectable portion 110 serves as an acting portion that changes the posture of the connecting / disconnecting lever 202 when connecting the display main body 101 and the mounting portion 300, and the inclined surface 2022 of the connecting / disconnecting lever 202 serves as a non-acting portion. In this embodiment, the inclined surface 2022 as the non-acting portion is an inclined surface having a convex arc-shaped cross section perpendicular to the rotation axis, but may be an inclined surface having a linear cross section, for example.

[0035] 4(c) is a schematic diagram showing the state when the connection between the main body side connectable part 110 and the main body side connecting part 201 of the connecting mechanism unit 200 is released and the display main body 101 is removed from the mounting part 300. The release lever part 2024 is a protrusion provided on the connecting / disconnecting lever 202, and the connection between the display main body 101 and the connecting mechanism unit 200 is released by pushing down this protrusion in the direction of the outlined arrow in the figure. That is, when the user pushes the release lever part 2024 to the left in the figure (the direction of the outlined arrow in the figure) as a predetermined operation direction against the biasing force of the spring 203, the connecting / disconnecting lever 202 rotates counterclockwise around the rotation shaft 2021. As a result, the posture of the coupling / disconnecting lever 202 changes from the engaged posture to the disengaged posture, the convex portion 1102 of the main body side coupled portion 110 disengages from the concave portion of the coupling / disconnecting lever 202, and the contacted surface 1103 and the contact surface 2023 no longer face each other in the direction D2. In other words, the contacted surface 1103 and the contact surface 2023 no longer overlap when viewed in the direction D2, and the main body side coupled portion 110 and the main body side coupling portion 201 are no longer coupled together. At this time, the biasing force of the spring 111 acts to separate the display main body 101 and the coupling mechanism unit 200, thereby urging the display main body 101 to move away from the mounting portion 300. This makes it possible to remove the display main body 101 from the mounting portion 300 simply by pressing the release lever 2024.

[0036] 5(a) and 5(b) are schematic diagrams showing the positional relationship between the mounting unit-side coupling part 210 and the connection mechanism unit 200. In the connection mechanism unit 200 of this embodiment, a protective wall 2101 serving as a cover is disposed in the mounting unit-side coupling part 210 as a configuration for preventing the user from unintentionally detaching the display main body 101 and the mounting unit 300. The protective wall 2101 is a protrusion provided so as to protrude toward the user's eyes from the side of the mounting unit-side coupling part 210 serving as the second coupling part, which faces the user's head. The release lever part 2024 is provided on the side of the main body-side coupling part 201 serving as a movable part, which faces the user's head. The protective wall 2101 is configured to be disposed so as to extend between the release lever part 2024 and the user's head in order to prevent the release lever part 2024 from being accidentally operated.

[0037] FIG. 5(a) shows the positional relationship between the wearing unit 300 and the display main body 101 when the user places the display main body 101 in front of the user's eyes. In this embodiment, this state is referred to as a first state. At this time, the positional relationship between the wearing unit 300 and the display main body 101 is a positional relationship (first relative position) suitable for the user to have an XR experience. That is, this positional relationship is a positional relationship in which, when the wearing unit 300 is worn on the user's head, the display main body 101 takes a position (first position) facing the user's eyes so that the user can see the image displayed by the display main body 101.

[0038] In the first state, the release lever portion 2024 is covered by a protective wall 2101 disposed in the mounting portion side coupling portion 210, making it difficult to touch with a finger. That is, in the first state, the protective wall 2101 is configured to be in a position where it covers the release lever portion 2024 (cover position) and is also in a position where it restricts the user's operation of the release lever portion 2024 (restriction position).

[0039] This position is where the protective wall 2101 faces the release lever portion 2024 in the above-described operation direction (the direction of the white arrow in the figure). Also, this position is where the protective wall 2101 overlaps with the release lever portion 2024 when viewed in the above-described operation direction. That is, as shown in FIG. 5(a), the protective wall 2101 is located at a position where it overlaps with an overlap region OR indicated by a dashed arrow in the above-described operation direction.

[0040] By arranging the protective wall 2101 as described above, it is possible to prevent the user's hand or head from touching the release lever portion 2024 during the XR experience, which may result in the display main body 101 being unintentionally detached from the mounting portion 300.

[0041] The protective wall 2101 also has the function of restricting the rotational position of the display main body 101 relative to the mounting unit 300. That is, if the display main body 101 rotates counterclockwise in the figure around the rotation axis 211 relative to the mounting unit 300, the display main body 101 may come closer to the face than necessary, preventing an appropriate XR experience. To avoid such a situation, the protective wall 2101 is configured to restrict the display main body 101, which is in the first relative position, from moving further toward the user's face (eyes). Specifically, the protective wall 2101 is configured so that its tip side can abut against members such as the main body-side coupling unit 201, the coupling / release lever 202, or the display main body 101. When the protective wall 2101 comes into contact with these members, it becomes possible to prevent the display main body 101 from rotating more than necessary and coming closer to the user's face.

[0042] FIG. 5B is a schematic diagram showing a state when a user removes the display main body 101 from the mounting unit 300. When attempting to remove the display main body 101 from the mounting unit 300, the user holds the display main body 101 and the mounting unit 300 with their hands and tries to separate them. In this state, the state in which force is most easily applied is a state in which the main body-side coupling unit 201 rotates around the rotation axis 211 with respect to the mounting unit-side coupling unit 210 fixedly held by the mounting unit 300, resulting in the display main body 101, the connecting mechanism unit 200, and the mounting unit 300 being aligned in a substantially straight line. More specifically, this is a state in which the direction D1 (first direction) in which the mounting unit-side coupling unit 210 protrudes from the mounting unit 300 and the direction D2 (second direction) in which the main body-side coupler unit 110 protrudes from the display main body 101 are substantially parallel to each other. In this state, the mounting unit-side coupling unit 210 and the main body-side coupler unit 110 are aligned along the directions D1 and D2. This state is referred to as the second state in this embodiment.

[0043] The positional relationship (second relative position) between the display main body 101 and the mounting unit 300 in this second state is a positional relationship in which the display main body 101 is positioned (second position) farther from the user's face (eyes) than in the first state. This positional relationship (second relative position) is also a relative position that can be taken when the mounting unit 300 is attached to or detached from the user's head. The angle formed between the D1 direction in which the mounting unit side coupling portion 210 protrudes from the mounting unit 300 and the D2 direction in which the main body side coupler portion 110 protrudes from the display main body 101 is smaller in the second relative position than in the first relative position described above. This positional relationship makes it easier for the user to apply force to separate and remove the display main body 101 and the mounting unit 300.

[0044] At this time, the distance between the mounting unit side coupling portion 210 and the release lever portion 2024 in the second state is larger than the distance between the mounting unit side coupling portion 210 and the release lever portion 2024 in the first state. More specifically, the distance between the protective wall 2101 of the mounting unit side coupling portion 210 and the release lever portion 2024 in the second state is larger than the distance in the first state, and they are farther apart from each other than in the first state.

[0045] At this time, the position of the protective wall 2101 relative to the release lever portion 2024 is farther from the release lever portion 2024 than when in the cover position described above, and is a position (non-cover position) that does not cover the release lever portion 2024. Also, the position of the protective wall 2101 relative to the release lever portion 2024 at this time is a position (allow position) that allows the user to operate the release lever portion 2024, as opposed to the restricting position described above.

[0046] This position is a position where the protective wall 2101 is not positioned opposite the release lever portion 2024 in the above-described operation direction (the direction of the white arrow in the figure). Also, this position is a position where, when viewed in the above-described operation direction, the protective wall 2101 does not overlap with the release lever portion 2024. That is, as shown in FIG. 5(b), the protective wall 2101 is in a position where it does not overlap with the overlap region OR indicated by the dashed arrow along the above-described operation direction.

[0047] Note that if a positional relationship can be formed in which the overlapping range of the protective wall 2101 with the overlap region OR is smaller than in the first state and the user is not prevented from operating the release lever portion 2024, then that positional relationship may be designated the second state. That is, in the second state, the protective wall 2101 may not completely move away from a position facing the above-described operation direction with respect to the release lever portion 2024, and an overlapping range with the overlap region OR may remain. Similarly, in the second state, the D1 direction and the D2 direction may not be completely parallel, and the angle formed between them may be smaller than that in the first state.

[0048] With the above configuration, as shown in the drawing, the release lever portion 2024 is exposed from the protective wall 2101 and can be easily touched by the user's finger. This makes it easy to operate the release lever portion 2024 when the user tries to remove the HMD 100 from their head, making it possible to easily replace the mounting portion 300.

[0049] That is, reattaching the mounting unit 300 (removing the display main body 101 and the mounting unit 300) requires an operation step of changing from a restrictive mode that restricts operation of the coupling / release lever 202 to an allowable mode that allows operation of the coupling / release lever 202. In this embodiment, the mode that the HMD 100 takes when worn on the head and used matches the restrictive mode that restricts operation of the release lever unit 2024. Also, the mode that the HMD 100 can take when worn on or detached from the head matches the allowable mode that allows operation of the release lever unit 2024. As a result, the operation that occurs when removing the HMD 100 from the head (from the mode shown in FIG. 5(a) to the mode shown in FIG. 5(b)) also serves as the operation step of changing from the restrictive mode to the allowable mode described above. Therefore, it is possible to remove the display main body 101 and the mounting unit 300 with fewer operations.

[0050] Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and changes are possible within the scope of the gist of the present invention.

[0051] For example, the configuration of the coupling mechanism unit 200 fixed to one of the display main body 101 and the mounting section 300 and the configuration of the coupling mechanism unit 200 fixed to the other may be reversed from that of this embodiment. That is, the coupling mechanism unit 200 may be configured such that a configuration similar to the main body-side joinable section 110 is provided in the mounting section 300, and configurations similar to the main body-side coupling section 201, the coupling / release lever 202, and the mounting section-side coupling section 210 are provided in the display main body 101. Furthermore, the movable section (main body-side coupling section 201) of the coupling mechanism unit 200 that changes the angle (relative position) between the display main body 101 and the mounting section 300 may be provided not only in the mounting section-side configuration provided in the mounting section 300, but also in the main body-side configuration provided in the display main body 101.
