Abstract
Description
Technical Field
[0001] This application relates to the field of near-eye displays, and more particularly to a near-eye display device. Background Technology
[0002] Common near-eye display devices typically place imaging modules in front of each of the user's eyes, projecting images separately to each eye to create a near-eye image using the principle of binocular imaging. During use, the interpupillary distance (IPD) of both eyes needs to coincide with the optical center of the imaging module to achieve good alignment, improve comfort, and enhance image quality. If the optical center of the imaging module does not match the IPD, it can lead to visual fatigue, blurred vision, and even myopia or changes in eye alignment. Existing near-eye display devices usually correspond to a fixed IPD, resulting in poor versatility. Utility Model Content

[0063] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation
[0064] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0065] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0066] To further illustrate the technical means and effects adopted by this application in achieving its intended purpose, the following detailed description of this application is provided in conjunction with the accompanying drawings and preferred embodiments.
[0067] Please refer to the following: Figure 1 and Figure 2 The near-eye display device 100 provided in this application embodiment includes a housing 10, a first imaging module 30, a second imaging module 40, a first elastic member 50, a second elastic member 60, and an adjusting member 70. The first imaging module 30 and the second imaging module 40 are movably disposed within the housing 10. The first elastic member 50 is disposed between the first imaging module 30 and the housing 10, and provides elastic force to the first imaging module 30 to move closer to or away from the housing 10. The second elastic member 60 is disposed between the second imaging module 40 and the housing 10, and provides elastic force to the second imaging module 40 to move closer to or away from the housing 10. The adjusting member 70 is at least partially disposed between the first imaging module 30 and the second imaging module 40, and is used to adjust the distance between the first imaging module 30 and the second imaging module 40.
[0068] Specifically, please refer to Figure 3 The housing 10, the first elastic member 50, the first imaging module 30, and the adjusting member 70 together form a balanced interaction force. One end of the first elastic member 50 abuts against the inner side wall of the housing 10, and the other end abuts against one side of the first imaging module 30. The other side of the first imaging module 30 abuts against the adjusting member 70. The adjusting member 70 can move to drive the first imaging module 30 to move, thereby moving the first imaging module 30 in the direction of approaching or moving away from the first elastic member 50.
[0069] The housing 10, the second elastic member 60, the second imaging module 40, and the adjusting member 70 together form another balanced interaction force. One end of the second elastic member 60 abuts against the inner side wall of the housing 10, and the other end abuts against one side of the second imaging module 40. The other side of the second imaging module 40 abuts against the adjusting member 70. The adjusting member 70 can move to drive the second imaging module 40 to move, thereby moving the second imaging module 40 in the direction of approaching or moving away from the second elastic member 60.
[0070] The first imaging module 30 includes a first frame 31, a first optical engine 33, a first imaging medium 35, and a first rotating member 37. The first frame 31 at least partially surrounds the first imaging medium 35. The first optical engine 33 is disposed on one side of the first imaging medium 35 and is used to emit image light into the first imaging medium 35. The first imaging medium 35 is used to guide the image light into the user's eye. The first rotating member 37 is disposed on the first frame 31 and is used to rotate the first imaging medium 35.
[0071] The first imaging medium 35 is a lens for near-eye display imaging. For example, the first imaging medium 35 can be a lens for augmented reality display, such as an optical waveguide or a holographic diffraction waveguide. The first imaging medium 35 is used to receive and transmit the image light emitted from the first optomechanical system 33, and modulate the image light before emitting it, thereby forming a near-eye display image in the user's eyes.
[0072] The first optical engine 33 can be a display screen component that directly displays images, or it can be a projector optical engine that forms images through projection; this application does not limit this.
[0073] In other embodiments, the first imaging medium 35 may also be a lens for virtual reality display, such as a folded optical path lens group or a Fresnel lens. The first optical engine 33 is directly disposed on one side of the first imaging medium 35 and emits image light to the other side of the first imaging medium 35. The first imaging medium 35 modulates the image light to form a near-eye display image in the user's eye. This application does not limit the specific imaging principle of the first imaging module 30.
[0074] The first frame 31 at least partially surrounds the first imaging medium 35, thereby fixing and protecting the first imaging medium 35. Specifically, the first frame 31 is disposed around the first imaging medium 35 and is used to abut against the first elastic member 50 and the adjusting member 70, thereby driving the first imaging medium 35 to move under the action of the first elastic member 50 and the adjusting member 70.
[0075] The second imaging module 40 includes a second frame 41, a second optical engine 43, a second imaging medium 45, and a second rotating member 47. The second frame 41 at least partially surrounds the second imaging medium 45. The second optical engine 43 is disposed on one side of the second imaging medium 45 and is used to emit image light into the second imaging medium 45. The second imaging medium 45 is used to guide the image light into the user's eye. The second rotating member 47 is disposed on the second frame 41 and is used to rotate the second imaging medium 45.
[0076] The second imaging medium 45 is a lens for near-eye display imaging. For example, the second imaging medium 45 can be a lens for augmented reality display, such as an optical waveguide or a holographic diffraction waveguide. The second imaging medium 45 is used to receive and transmit the image light emitted from the second optomechanical system 43, and modulate the image light before emitting it, thereby forming a near-eye display image in the user's eyes.
[0077] The second optical engine 43 can be a display screen assembly that directly displays images, or it can be a projector optical engine that forms images through projection; this application does not limit this.
[0078] In other embodiments, the second imaging medium 45 may also be a lens for virtual reality display, such as a folded optical path lens group or a Fresnel lens. The second optical engine 43 is directly disposed on one side of the second imaging medium 45 and emits image light to the other side of the second imaging medium 45. The second imaging medium 45 modulates the image light to form a near-eye display image in the user's eye. This application does not limit the specific imaging principle of the second imaging module 40.
[0079] The second frame 41 at least partially surrounds the second imaging medium 45, thereby fixing and protecting the second imaging medium 45. Specifically, the second frame 41 is disposed around the second imaging medium 45 and is used to abut against the second elastic member 60 and the adjusting member 70, thereby driving the second imaging medium 45 to move under the action of the second elastic member 60 and the adjusting member 70.
[0080] Please refer to the following: Figure 3 and Figure 4In this embodiment, the first frame 31 includes a first inclined surface 311, and an adjusting member 70 abuts against the first inclined surface 311. The adjusting member 70 drives the first imaging module 30 to move relative to the second imaging module 40 through the first inclined surface 311. Specifically, the adjusting member 70 can move in a direction perpendicular to the moving direction of the first imaging module 30. The first inclined surface 311 is inclined relative to the moving direction of the adjusting member 70. The adjusting member 70 is at least partially disposed between the first imaging module 30 and the second imaging module 40, thereby abutting against the first inclined surface 311. When the adjusting member 70 moves toward the first imaging module 30 and the second imaging module 40, the adjusting member 70 exerts a force on the first inclined surface 311. Since the first inclined surface 311 is inclined relative to the moving direction of the adjusting member 70, the force forms a component force toward the first elastic member 50 on the first inclined surface 311, thereby driving the first imaging module 30 to move toward the first elastic member 50.
[0081] In other embodiments, the first frame 31 may also be provided with a rack and pinion structure (not shown in the figure), with the adjusting member 70 meshing with the rack and pinion structure to drive the first imaging module 30 to move via gear transmission. The adjusting member 70 may also be a motor connected to the first imaging module 30, driving the first imaging module 30 to move via the motor. This application does not limit the specific driving structure between the adjusting member 70 and the first imaging module 30.
[0082] In this embodiment, the second frame 41 includes a second inclined surface 411, and an adjusting member 70 abuts against the second inclined surface 411. The adjusting member 70 drives the second imaging module 40 to move relative to the first imaging module 30 via the second inclined surface 411. Specifically, the adjusting member 70 can move in a direction perpendicular to the moving direction of the second imaging module 40. The second inclined surface 411 is inclined relative to the moving direction of the adjusting member 70. The adjusting member 70 is at least partially disposed between the second imaging module 40 and the first imaging module 30, thereby abutting against the second inclined surface 411. When the adjusting member 70 moves toward the first imaging module 30 and the second imaging module 40, the adjusting member 70 exerts a force on the second inclined surface 411. Since the second inclined surface 411 is inclined relative to the moving direction of the adjusting member 70, the force forms a component force on the second inclined surface 411 toward the second elastic member 60, thereby driving the second imaging module 40 to move toward the second elastic member 60.
[0083] In other embodiments, the second frame 41 may also be provided with a rack and pinion structure (not shown in the figure), with the adjusting member 70 meshing with the rack and pinion structure to drive the second imaging module 40 to move via gear transmission. The adjusting member 70 may also be a motor connected to the second imaging module 40, driving the second imaging module 40 to move via the motor. This application does not limit the specific driving structure between the adjusting member 70 and the second imaging module 40.
[0084] In this embodiment, the adjusting member 70 is specifically a bolt structure. The adjusting member 70 includes a screw head 71 and a screw rod 73. The adjusting member 70 is threadedly connected to the housing 10. The screw head 71 is located on the outside of the housing 10, and the screw rod 73 passes through the housing 10 and connects to the inside of the housing 10 to abut against the first frame 31 and / or the second frame 41.
[0085] Specifically, in this embodiment, there is one adjusting member 70. The screw 73 of the adjusting member 70 simultaneously abuts against the first inclined surface 311 of the first frame 31 and the second inclined surface 411 of the second frame 41. By rotating the screw head 71, the screw 73 can be rotated, thereby moving the adjusting member 70 towards or away from the first imaging module 30 and the second imaging module 40. When the adjusting member 70 is not rotated, due to the threaded structure between the adjusting member 70 and the housing 10, the force applied by the first imaging module 30 and the second imaging module 40 to the adjusting member 70 will not cause the adjusting member 70 to move. Therefore, the position of the adjusting member 70 can be fixed, thereby keeping the distance between the first imaging module 30 and the second imaging module 40 fixed after adjustment.
[0086] In other embodiments, the number of adjusting members 70 may also be two (not shown in the figure), that is, the two adjusting members 70 are respectively set for the first imaging module 30 and the second imaging module 40, thereby adjusting the positions of the first imaging module 30 and the second imaging module 40 respectively. This application does not limit this.
[0087] The first rotating component 37 includes a first knob 371 and a first slide groove 373. The first slide groove 373 is fastened to the first frame 31, and the first knob 371 is fixed to the side of the first slide groove 373 away from the first frame 31. The first rotating component 37 is used to drive the first imaging medium 35 to rotate.
[0088] Specifically, the first knob 371 is located on the outside of the housing 10, and the first slide 373 is fastened to the first frame 31. When the first knob 371 is rotated, the first knob 371 drives the first slide 373 to rotate, thereby driving the first frame 31 and the first imaging medium 35 to rotate.
[0089] The first groove 373 is also used to limit the movement of the first frame 31. Specifically, the groove of the first groove 373 extends in the direction of movement of the first frame 31, and the first groove 373 is fastened to the first frame 31, thereby forming a slide rail structure that guides the movement of the first frame 31.
[0090] The second rotating component 47 includes a second knob 471 and a second slide groove 473. The second slide groove 473 is fastened to the second frame 41, and the second knob 471 is fixed to the side of the second slide groove 473 away from the second frame 41. The second rotating component 47 is used to drive the second imaging medium 45 to rotate.
[0091] Specifically, the second knob 471 is located on the outside of the housing 10, and the second slide 473 is fastened to the second frame 41. When the second knob 471 is rotated, the second knob 471 drives the second slide 473 to rotate, thereby driving the second frame 41 and the second imaging medium 45 to rotate.
[0092] The second slide 473 is also used to limit the movement of the second frame 41. Specifically, the groove of the second slide 473 extends in the direction of movement of the second frame 41, and the second slide 473 is fastened to the second frame 41, thereby forming a slide rail structure that guides the movement of the second frame 41.
[0093] The first rotating member 37 and the second rotating member 47 are used to adjust the orientation of the first imaging module 30 and the second imaging module 40, thereby adjusting the overlap position of the binocular images. Specifically, the near-eye display device 100 is used to form a near-eye display image in front of the user's eyes. The near-eye display image is formed by overlapping the images seen by the user's two eyes. Therefore, the user's eyes converge on the near-eye display image after passing through the first optical center A1 of the first imaging module 30 and the second optical center A2 of the second imaging module 40, respectively. That is, the optical axes of the first imaging module 30 and the second imaging module 40 intersect after passing through the user's two eyes. Therefore, when adjusting the distance between the first imaging module 30 and the second imaging module 40, it is also necessary to adjust the angle between the first imaging module 30 and the second imaging module 40 to ensure that the user can see a clear near-eye display image.
[0094] Please refer to the following: Figure 1 , Figure 2 and Figure 3The housing 10 has a display window 11, a rotation adjustment hole 13, and an interpupillary distance adjustment hole 14. There are two display windows 11, corresponding to the first imaging module 30 and the second imaging module 40, respectively. The display windows 11 are positioned to accommodate the user's eyes and transmit the image light emitted from the first imaging module 30 and the second imaging module 40. There are two rotation adjustment holes 13, corresponding to the first rotating member 37 and the second rotating member 47, respectively, such that the first knob 371 and the second knob 471 are partially located on the outside of the housing 10, thereby facilitating the rotation of the first imaging module 30 and the second imaging module 40. The interpupillary distance adjustment hole 14 is formed at a position between the first imaging module 30 and the second imaging module 40. The interpupillary distance adjustment hole 14 accommodates an adjustment member 70. In this embodiment, the wall of the interpupillary distance adjustment hole 14 has threads, and the adjustment member 70 passes through the interpupillary distance adjustment hole 14 to abut against the first frame 31 and the second frame 41.
[0095] Please refer to the following: Figure 2 and Figure 5 The near-eye display device 100 also includes a package 20, a first corrective lens 80, and a second corrective lens 90. The first corrective lens 80 is detachably disposed on the light-emitting side of the first imaging module 30, and the second corrective lens 90 is detachably disposed on the light-emitting side of the second imaging module 40.
[0096] Specifically, the first corrective lens 80 includes a first lens 81 and a first slider 83. The first slider 83 is disposed on one side of the first lens 81 and extends in a direction away from the first lens 81. The first lens 81 specifically includes optical lenses for vision correction such as myopia lenses and hyperopia lenses. The first lens 81 is used to modulate the image light emitted from the first imaging module 30, thereby adapting it to the user's vision. The first slider 83 is used to fix the first lens 81.
[0097] The second corrective lens 90 includes a second lens 91 and a second slider 93. The second slider 93 is disposed on one side of the second lens 91 and extends in a direction away from the second lens 91. The second lens 91 specifically includes optical lenses for vision correction such as myopia lenses and hyperopia lenses. The second lens 91 is used to modulate the image light emitted from the second imaging module 40, thereby adapting it to the user's vision. The second slider 93 is used to fix the second lens 91.
[0098] The housing 10 also has a mounting hole 12 for the first lens 81 and the second lens 91 to pass through. The first slider 83 and the second slider 93 are at least partially accommodated in the mounting hole 12. The encapsulation member 20 is used to fill the mounting hole 12, thereby fixing the first slider 83 and the second slider 93, and further fixing the first lens 81 and the second lens 91.
[0099] A limiting structure (not shown in the figure) may also be provided on the housing 10. The limiting structure is used to limit the position of the first lens 81 together with the first slider 83, and to limit the position of the second lens 91 together with the second slider 93.
[0100] The near-eye display device 100 provided in this application embodiment, by setting up a housing 10, a first elastic member 50, a first imaging module 30, an adjustment member 70, and a housing 10, a second elastic member 60, a second imaging module 40, and an adjustment member 70, allows the adjustment member 70 to adjust the distance between the first imaging module 30 and the second imaging module 40, thereby adapting to the interpupillary distance of different users. By setting up a first correction lens 80 and a second correction lens 90, the overlap position of binocular imaging can be adjusted, thereby improving the quality of binocular imaging, which is beneficial to improving the applicability of the near-eye display device 100, thereby enhancing the user's immersion and comfort.
