Referring to fig. 1, a head mounted display device 100 in a first embodiment of the present disclosure is disclosed. The head-mounted display device 100 includes a main body 20 and two display modules 10 rotatably disposed on the main body 20. The two display modules 10 are screens viewed by the left and right eyes of the wearer, respectively. Each display module 10 is rotatable relative to the body 20 to enable each display module 10 to achieve an inward display mode when its display surface 101 (as shown in fig. 4) is turned to a direction to view the inside exit light sources and an outward display mode when it is turned to view the outside exit light sources, thereby providing switching between the inward display mode toward the wearer and the outward display mode when the display surface 101 is toward the other than the wearer. The light source of the display module 10 provides the display surface 101 with a light source of display content, and the display content can be specifically understood as an image. Thus, when the wearer needs to share the display content with other people, one or two of the display modules 10 can be switched to the external display mode, so that the display content sharing is realized.
Referring to fig. 2, the head-mounted display device 100 further includes a headband 30 connected to the body 20 and used for wearing the head-mounted display device 100 on the head of a wearer, an earphone 40, a speaker 42 disposed on the body 20, and a processor 50. The processor 50 is electrically connected to the earphones 40, the two display modules 10, and the speaker 42 for signal processing. The processor 50 is mounted in the head-mounted display device 100 in the present embodiment, for example, disposed in the body 20. It is understood that in other embodiments, the processor 50 and/or the power supply may be separate independent devices and connected to the head-mounted display apparatus 100 through a plug-in interface. The speaker 42 may be disposed at any position of the head-mounted display device 100, for example, the headband 30 or the earphone 40.
Referring to fig. 3, 4 and 6, the two display modules 10 are rotatably disposed on the main body 20. Each display module 10 may be an integrated structure including the display 102 and the optical module 104, or may be a single display 102 structure independent of the optical module 104. The optical module 104 is a special optical lens, and is configured to project an enlarged virtual image from a light source provided by the corresponding display surface 101 according to a preset light path, so that a small-sized screen can project a display effect of a large screen. Specifically, the light source provided by the display surface 101 of the display module 10 passes through the optical module 104 and then is projected to both eyes of the wearer through the viewing window. It is to be understood that the illustration is merely a schematic representation and is not intended to limit the specific locations of the various modules of the invention. In other embodiments, the viewing outer side can be flexibly selected according to the requirement, and the rotatable display module 10 is disposed in the corresponding region of the viewing outer side. For example, the display module 10 can be disposed at two opposite sides of the main body 20 to be shared with the outside, as shown in fig. 5, when the display module is to be shared with the outside through the side of the main body, the display surface 101 can be rotated to the outside through the side in the mode. In the inward display mode, the display surface 101 may rotate to face the viewing window 21 corresponding to the viewing inner side 20A, or may rotate to other directions, as long as in this mode, the display surface 101 faces the light incident side of the optical module 104, and the light path designed by the optical module 104 forms an outgoing light beam through the viewing window 21 corresponding to the viewing inner side 20A. The display 10 can be placed anywhere on the body according to the principles of the present invention described above.
Specifically, the integrated structure may be any structure that can relatively fix the display 102 and the corresponding optical module 104, and has a structure that can emit light beams, for example, the display module 10 may include a closed box body that fixes the display and the optical module, and a viewing window that emits light beams is disposed at a position of the box body corresponding to the emitted light beams formed by the light source of the display surface 101; the display module 10 may also include a fixing base for fixing the display 102 and the optical module 104 without shielding the display surface 101. In this manner, the optical module 104 can rotate with the display 102. In the present embodiment, the two display modules 10 are substantially rectangular. It is understood that in other embodiments, the two display modules 10 may also be oval, regular polygon, etc. Each of the display modules 10 is provided with a rotation shaft 150 at two opposite sides (e.g., an upper side and a lower side). The two shafts 150 are disposed coaxially with the axis a. The axes a are in this embodiment axes of symmetry of the display module 10, respectively. The shaft 150 is further opened with a through hole 152 to allow a signal line connected to the display module 10 to pass through. In the present embodiment, the through hole 152 extends along the axis a, and forms an opening at the end of the rotation shaft 150 far away from the display module 10. In other embodiments, the rotation shaft 150 can be disposed on two opposite sides (e.g., a left side and a right side) of the display module 10, and the coaxial axis is perpendicular to the axis a in this embodiment.
The body 20 may be a frame similar to a pair of glasses, or a box with an internal space, as shown in fig. 5, the viewing inner side 20A of the box, i.e. one side corresponding to the two eyes of the user, is provided with a viewing window 21 for projecting light beams for the wearer to view. The body 20 also includes a viewing exterior 20B. The viewing outer side 20B of the main body 20 further defines an opening 210 for emitting light from the display module 10 in an external display mode. The shape of the opening 210 is adapted to the shape of the display module 10. Specifically, when the main body 20 is in the above-mentioned box structure, the opening 210 is disposed on the viewing outer side 20B, i.e. the non-viewing inner side 20A, and may be, for example, the side opposite to the viewing window 21, the left side, the right side, the upper side, and the bottom side. In the example provided in connection with fig. 1 to 4, the body 20 is provided with two substantially rectangular openings 210. The two openings 210 are used to mount two display modules 10, respectively. The upper sidewall 211 and the lower sidewall 212 of each opening 210 are opened with a shaft hole 214 for receiving the rotating shaft 150. The shaft 150 is rotatably received in the shaft hole 214, so that the display module 10 can rotate relative to the main body 20, and the display surface 101 of the display module 10 can be switched from an inward display mode facing the direction of emitting light from the viewing inner side 20A to an outward display mode facing other people except the wearer through the opening 210, so as to allow the wearer to share display contents with other people. The opening 210 is axially symmetric with respect to a connecting line of the two shaft holes 214. The inner wall of the shaft hole 214 is opened with a through hole (not shown) corresponding to the through hole 152 to allow the signal line connected to the display module 10 to be routed to the inside of the body 20 through the shaft hole 214 and the through hole 152, so as to realize the electrical connection with other modules of the wearable display device 100, including the electrical connection to the processor 50. In the mode, the internal space can be fully utilized, and the wiring is hidden in the wearable display device.
In this embodiment, the default sound display mode of the head-mounted display apparatus 100 is sound-in-play, i.e. playing through the earphone 40. When the display module 10 is switched to the outward display mode, the sound outward playing is automatically started, i.e. the speaker 42 is started to play. Specifically, the head-mounted display device 100 further includes two rotation sensors 60. The two rotation sensors 60 are electrically connected to the processor 50, and are configured to detect a state of the display module 10 and generate a detection signal when detecting that any display module 10 is switched to the outward display mode. The processor 50 is arranged to initiate a sound play-out mode, i.e. to control the audio signal to be played out through the loudspeaker 42, when the detection signal is received. Therefore, the wearer can synchronously share the audio and the display content with other people, and the user experience is improved. It will be appreciated that initiating sound playback upon receiving the detection signal includes both the earphone 40 playing simultaneously with the speaker 42 and also includes directly switching the speaker 42 to play when the earphone 40 stops playing. The corresponding play selection mode can be flexibly set and can be preferably provided for a user to carry out self-configuration selection.
In connection with the embodiment of fig. 4, the head-mounted display device 100 further includes a latch assembly 70. In this example, two locking assemblies 70 are respectively disposed on the two display modules 10 for locking the display modules 10 when the display modules 10 are in the inward display mode or the outward display mode. The latch assembly 70 includes a latch member 72 movably disposed on the display module 10, an elastic member (not shown) abutting against the latch member 72 to extend the latch member 72 out of the display module 10, and a button 74 for driving the latch member 72 to retract the display module 10. The two opposite sidewalls of the opening 210 are both provided with a fastening groove 216 for fastening the locking element 72. The catch member 72 locks the display module 10 in cooperation with the catching groove 216. Specifically, when the display module 10 is in the inward display mode, the locking member 72 is locked to the locking groove 216 of the left sidewall to lock the display module 10, thereby keeping the inward display mode unchanged. When it is required to switch to the outward display mode, the button 74 is pressed, the locking element 72 is separated from the engaging groove 216 of the left sidewall and retracts into the display module 10, specifically, the button 74 is pressed to drive the spring element to drive the locking element 72 to retract into the display module 10, at this time, the display module 10 is rotated by 180 degrees, and the locking element 72 is engaged with the engaging groove 216 of the right sidewall to lock and maintain the display module 10 in the outward display mode.
It is understood that in other embodiments, the latch assembly 70 is disposed on the body 20, and the display module 10 has engaging grooves 216 formed on two opposite sides thereof. The engagement groove 216 cooperates with the locking member 72 to lock the display module 10 to maintain the display module 10 in the outward display mode or the inward display mode.
In other embodiments, the locking assembly can be any lockable structure, such as a limiting structure, a locking structure, a magnetic attraction structure, and the like.
In one embodiment, the front and back sides of the edge of the display module 10 are provided with the operation components 801. When the wearer rotates the display module 10, the operation assembly 801 is buckled to tilt the display module 10, so that the display module 10 can be rotated smoothly.
When assembling, the rotating shaft 150 is rotatably received in the shaft hole 214, and the signal line is electrically connected to the processor 50 after passing through the through hole 152 and the through hole, so that the display module 10 is mounted to the body 10.
As shown in fig. 6, when the wearer does not need to share the display content with another person during use, the display module 10 can be switched to the inward display mode, in which the display surface 101 of the display module 10 faces the left and right eyes of the wearer. As shown in fig. 7, when the wearer needs to share the video with another person, one or two of the display modules 10 are rotated to switch the display module 10 to the outward display mode, and at this time, the display surface 101 of the display module 10 is turned to the viewing outer side 20B, so that the other person can see the display content. At the same time, the rotation sensor 60 generates a detection signal, and the processor 50 controls the audio signal to be played out through the speaker 42. Therefore, the wearer can synchronously share the audio and the display content with other people, and the user experience is improved.
As shown in fig. 8, in another embodiment of the present invention, the display module 10 is a single display 102 structure independent of the optical module 104 and disposed corresponding to the optical module 104. The display module 10 is rotatably disposed on the body 20 based on the above-mentioned rotation structure to realize switching between the inward display mode and the outward display mode. The body 20 is also provided with a converging lens 106. The converging lens 106 corresponds to the display module 10 and is used for magnifying the display contents of the display module 10 for others to view when the display surface 101 of the display module 10 faces the viewing outer side 20B (in this case, the outward display mode). The converging lens 106 and the optical module 104 are disposed on opposite sides of the display module 10. Specifically, the converging lens 106 is disposed on the side of the body 20 where the opening 210 is opened. Preferably, the converging lens 106 is a fresnel lens in this embodiment. The converging lens 106 may be an optical element or a lens module capable of magnifying an image in other embodiments. In this mode, the display module 10 may be rotated by providing a rotating mechanism, for example, by a rotating knob fixedly connected to the rotating shaft 150. It is also possible to rotate the display module 10 in an electrically controlled manner by providing a drive motor, which may be electrically connected to the processor 50. Referring to fig. 5, the viewing inner side 20A has a viewing window 21 for a wearer to view, the opening 210 is disposed at two side ends of the main body 20, the converging lens 106 is corresponding to the shape of the opening 210 and is embedded in the opening 210, the display module 10 is disposed in the main body 20 corresponding to the opening 210, the upper side of the display module 10 is disposed with a rotating shaft 150, and the rotating shaft 150 is connected to the operating component 80 (see fig. 5) outside the main body 20 from inside the main body 20, specifically, the operating component is a rotating knob, and the rotating shaft 150 can be driven to rotate by rotating the operating component 80, so that the display surface 101 of the display module 10 can be turned to the converging lens 106, and the display surface 101 can also be turned to a direction of emitting light through the viewing inner side 20A, that is, the light source of the display surface 101 can be projected to both eyes of the user.
