Description

Technical Field

[0001] The utility model relates to the technical field of optical design, in particular to a near-eye display device. Background Art

[0002] Augmented Reality (AR) technology is an emerging technology that superimposes computer-generated virtual information onto the user's real world. It is an important branch of virtual reality technology. It improves the user's perception of the displayed world and provides a new way for humans to communicate with the world. In recent years, augmented reality technology has been widely used in industrial maintenance, film and television entertainment, medical surgery, education and training and other fields, and has gradually become the main direction of the development of the next generation of human-computer interaction technology.

[0003] Binocular parallax refers to the difference in imaging between the left and right eyes when the human eye looks at the same object. It is one of the important physiological factors for the human eye to judge the distance of an object. The farther the object is, the smaller the parallax is, and the closer the object is, the larger the parallax is. The central line of sight refers to the line connecting the center of the object and the center of the pupil when the binocular eyes are looking at a single object. When looking up at the starry sky, the central lines of sight of the binocular eyes are almost parallel, and the human eye feels that the starry sky is infinitely far away. When the binocular eyes are looking at the object in front of them, there is a certain angle between the central lines of sight of the binocular eyes, which makes the human eye feel that the object is close in front of it. Therefore, the distance of the virtual image can be adjusted by adjusting the angle of the central line of sight when the binocular virtual image is fused, thereby achieving the depth of field adjustment of the virtual image.

[0004] However, existing near-eye display devices usually have only one depth of field, and the depth of field is fixed and cannot be adjusted. When a person observes a virtual object, the binocular vision is always focused on one plane. When the human eye looks at a distant or near object, the vision needs to constantly switch back and forth between the real scene and the virtual image, making it difficult for the virtual object to be well integrated with the real environment, thereby causing dizziness to the user, reducing the user experience, and making it difficult to meet the needs of multi-scene use.

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0035] Reference below Figure 1-Figure 3The near-eye display device 100 according to the embodiment of the utility model is described. The near-eye display device 100 includes a bracket 10, a first adjusting member 20, a second adjusting member 30, a first fixing member 40, a second fixing member 50 and a cross beam 60. The near-eye display device 100 can superimpose computer-generated virtual information on the real world where the user is located, thereby realizing augmented reality display. Among them, the bracket 10, the first adjusting member 20, the second adjusting member 30, the first fixing member 40, the second fixing member 50 and the cross beam 60 can be made of the same material, for example, they can all be made of plastic, so that the mass of the near-eye display device 100 can be reduced and the user experience can be improved. Of course, the bracket 10, the first adjusting member 20, the second adjusting member 30, the first fixing member 40, the second fixing member 50 and the cross beam 60 can also be made of different materials, for example, the bracket 10 and the cross beam 60 are made of plastic, and the first adjusting member 20, the second adjusting member 30, the first fixing member 40 and the second fixing member 50 are made of metal, etc. The embodiment of the utility model does not limit this.

[0036] Please continue to refer to Figure 1-Figure 3 , further, the first adjusting member 20 and the second adjusting member 30 are arranged on the bracket 10, so that when the bracket 10 moves, the bracket 10 can drive the first adjusting member 20 and the second adjusting member 30 to move. The first fixing member 40 is rotatably connected to the first adjusting member 20, and the second fixing member 50 is rotatably connected to the second adjusting member 30. The first fixing member 40 and the second fixing member 50 are used to fix the left lens a and the right lens b respectively; it should be noted that the rotatable connection between the first fixing member 40 and the first adjusting member 20 means that the angle between the first fixing member 40 and the first adjusting member 20 can be changed, and similarly, the rotatable connection between the second fixing member 50 and the second adjusting member 30 means that the angle between the second fixing member 50 and the second adjusting member 30 can be changed.

[0037] The first fixing member 40 and the second fixing member 50 may be provided with a snap-fitting structure, so that the left lens a can be fixed on the first fixing member 40, and the right lens b can be fixed on the second fixing member 50. Of course, the left lens a can also be fixed on the first fixing member 40 by glue, and the right lens b can also be fixed on the first fixing member 40 by glue, and the embodiment of the utility model is not limited to this.

[0038] Please continue to refer to Figure 1-Figure 3 Furthermore, the bracket 10 is movably connected to the cross beam 60 through a connecting member 70, and the connecting member 70 can be adjusted so that the bracket 10 can be relative to the cross beam 60 in a first direction (such as Figure 2 The first adjusting member 20 and the second adjusting member 30 are driven to move in the first direction, so that the first fixing member 40 rotates relative to the first adjusting member 20, and the second fixing member 50 rotates relative to the second adjusting member 30, thereby adjusting the angle between the left lens a and the right lens b.

[0039] It should be noted that the adjusting connecting member 70 can make the bracket 10 move relative to the cross beam 60 in the first direction. Since the first adjusting member 20 and the second adjusting member 30 are arranged on the bracket 10, the first adjusting member 20 and the second adjusting member 30 can also move relative to the cross beam 60 in the first direction. Moreover, since the first fixing member 40 is rotatably connected to the first adjusting member 20, and the second fixing member 50 is rotatably connected to the second adjusting member 30, when the first adjusting member 20 and the second adjusting member 30 move in the first direction, the first fixing member 40 can rotate relative to the first adjusting member 20, so that the angle between the first fixing member 40 and the first adjusting member 20 changes. That is, the angle between the first fixing member 40 and the bracket 10 changes. Similarly, the second fixing member 50 can rotate relative to the second adjusting member 30, so that the angle between the second fixing member 50 and the second adjusting member 30 changes, that is, the angle between the second fixing member 50 and the bracket 10 changes. Since the left lens a is fixed on the first fixing member 40 and the right lens b is fixed on the second fixing member 50, the angle between the left lens a and the bracket 10 changes, and the angle between the right lens b and the bracket 10 changes. Therefore, the angle between the left lens a and the right lens b changes, and finally the depth of field of the virtual image projected by the near-eye display device 100 is adjusted.

[0040] The inventors found in actual research that existing near-eye display devices usually have only one depth of field, and the depth of field is fixed and cannot be adjusted. When a person observes a virtual object, the binocular vision is always focused on one plane. When the human eye looks at a distant or near object, the vision needs to constantly switch back and forth between the real scene and the virtual image, making it difficult for the virtual object to be well integrated with the real environment, thereby causing dizziness in the user, reducing the user experience, and making it difficult to meet the needs of multi-scene use.

[0041] In view of this, according to the near-eye display device 100 of the utility model, by setting the first fixing member 40 and the first adjusting member 20 to be rotatably connected, the second fixing member 50 and the second adjusting member 30 are also set to be rotatably connected, and the first adjusting member 20 and the second adjusting member 30 are arranged on the bracket 10, so when the adjusting connecting member 70 makes the bracket 10 move along the first direction relative to the beam 60, the first adjusting member 20 and the second adjusting member 30 can also move along the first direction, so that the first fixing member 40 and the first adjusting member 20 rotate relative to each other, and the second fixing member 50 and the second adjusting member 30 rotate relative to each other, so that the angle between the first fixing member 40 and the second fixing member 50 changes, and because the left lens a is fixed on the first fixing member 40 and the right lens b is fixed on the second fixing member 50, the angle between the left lens a and the right lens b changes, so that the depth of field of the virtual image projected by the near-eye display device 100 changes, thereby meeting the usage requirements of various scenarios and improving the user experience.

[0042] Please continue to refer to Figure 1-Figure 3 In some embodiments, a first positioning column 61 and a second positioning column 62 are provided on the beam 60, a first positioning groove 41 is provided on the first fixing member 40, and a second positioning groove 51 is provided on the second fixing member 50. The first fixing member 40 and the beam 60 are rotatably connected through the first positioning column 61 and the first positioning groove 41, and the first positioning column 61 provides a fulcrum for the first fixing member 40 to rotate relative to the beam 60 and the first adjusting member 20; the second fixing member 50 and the beam 60 are rotatably connected through the second positioning column 62 and the second positioning groove 51, and the second positioning column 62 provides a fulcrum for the second fixing member 50 to rotate relative to the beam 60 and the second adjusting member 30.

[0043] Among them, the first positioning column 61 provides a fulcrum for the first fixing member 40 to rotate relative to the cross beam 60 and the first adjusting member 20, which means that when the first adjusting member 20 moves along the first direction, the first fixing member 40 can rotate with the first positioning column 61 as the fulcrum. Similarly, the second positioning column 62 provides a fulcrum for the second fixing member 50 to rotate relative to the cross beam 60 and the second adjusting member 30, which means that when the second adjusting member 30 moves along the second direction, the second fixing member 50 can rotate with the second positioning column 62 as the fulcrum. The first positioning column 61 and the second positioning column 62 can be cylinders, and the first positioning groove 41 and the second positioning groove 51 can be circular grooves. In addition, the first positioning column 61 can also be set on the first fixing member 40, the second positioning column 62 can also be set on the second positioning member, and the first positioning groove 41 and the second positioning groove 51 are set on the cross beam 60, and the embodiment of the utility model does not limit this.

[0044] Therefore, by providing the first positioning column 61 and the second positioning column 62 as the fulcrum for the rotation of the first fixing member 40 and the second fixing member 50, the stability of the near-eye display device 100 can be improved, and the user experience of the near-eye display device 100 can be further improved.

[0045] It should be noted that, in some other embodiments, the near-eye display device may not be provided with the first positioning column 61, the second positioning column 62, the first positioning groove 41 and the second positioning groove 51. When adjusting the angle between the left lens a and the right lens b, the user can manually fix a point of the first fixing member 40 and the second fixing member 50 to provide a fulcrum for the rotation of the first fixing member 40 and the second fixing member 50.

[0046] Please continue to refer to Figure 1-Figure 3 In some embodiments, a first limiting groove 21 is provided on one of the first adjusting member 20 and the first fixing member 40, a first limiting column 42 is provided on the other of the first adjusting member 20 and the first fixing member 40, and the first fixing member 40 is rotatably connected to the first adjusting member 20 through the first limiting groove 21 and the first limiting column 42; specifically, the first limiting groove 21 may be provided on the first adjusting member 20, and the first limiting column 42 may be provided on the first fixing member 40, or the first limiting groove 21 may be provided on the first adjusting member 20, and the first limiting column 42 may be provided on the first fixing member 40, and the embodiment of the utility model is not limited to this.

[0047] Furthermore, a second limiting groove 31 is provided on one of the second adjusting member 30 and the second fixing member 50, a second limiting column 52 is provided on the other of the second adjusting member 30 and the second fixing member 50, and the second fixing member 50 and the second adjusting member 30 are rotatably connected through the second limiting groove 31 and the second limiting column 52. Similarly, the second limiting groove 31 may be provided on the second adjusting member 30, and the second limiting column 52 may be provided on the second fixing member 50, or the second limiting groove 31 may be provided on the second adjusting member 30, and the second limiting column 52 may be provided on the second fixing member 50, and the embodiment of the utility model is not limited thereto.

[0048] The first limiting column 42 and the second limiting column 52 may be cylinders, and the first limiting groove 21 and the second limiting groove 31 may be circular grooves.

[0049] Therefore, by utilizing the first limiting column 42 and the first limiting groove 21 to realize the rotatable cooperation between the first fixing member 40 and the first adjusting member 20, and utilizing the second limiting column 52 and the second limiting groove 31 to realize the rotatable cooperation between the second fixing member 50 and the second adjusting member 30, the near-eye display device 100 has a simple structure and further improves the user experience.

[0050] Please continue to refer to Figure 1-Figure 3In some embodiments, a groove 11 is provided on the bracket 10, a first boss 22 is provided on the first adjusting member 20, and a second boss 32 is provided on the second adjusting member 30. The first boss 22 and the second boss 32 are both provided in the groove 11, so that the first adjusting member 20 and the second adjusting member 30 are fixed relative to the bracket 10 in the first direction.

[0051] It can be understood that when the connecting member 70 is adjusted to make the bracket 10 move in the first direction relative to the cross beam 60, since the first adjusting member 20 and the second adjusting member 30 are fixed in the first direction relative to the bracket 10, the bracket 10 can drive the first adjusting member 20 and the second adjusting member 30 to move in the first direction relative to the cross beam 60. Therefore, by setting the first adjusting member 20 and the second adjusting member 30 to be fixed in the first direction relative to the bracket 10, the stability of the near-eye display device 100 can be improved, thereby further improving the user experience.

[0052] Please continue to refer to Figure 1-Figure 3 In some embodiments, the connecting member 70 includes an adjusting screw, a threaded hole 12 is provided on the bracket 10, the adjusting screw is connected to the bracket 10 through the threaded hole 12, a first through hole 63 is provided on the beam 60, the adjusting screw passes through the first through hole 63 and extends out of the beam 60, and the adjusting screw is rotated to make the bracket 10 move along the first direction relative to the beam 60.

[0053] It should be noted that since the adjusting screw is threadedly connected to the threaded hole 12 on the bracket 10, when the adjusting screw is turned, the bracket 10 moves along the first direction, thereby adjusting the position of the bracket 10 relative to the beam 60. Therefore, the near-eye display device 100 has a simple structure and further improves the user experience.

[0054] It is understandable that a thread may also be provided in the first through hole 63, so that the bracket 10 and the beam 60 can be connected and relatively fixed by adjusting the screw, thereby further improving the stability of the near-eye display device 100 and further improving the user experience.

[0055] In some optional embodiments, two threaded holes 12 are symmetrically arranged on the bracket 10, two first through holes 63 are correspondingly arranged on the crossbeam 60, and two connectors 70 are arranged. Thus, the symmetrically arranged connectors 70 further improve the stability of the near-eye display device 100, thereby further improving the user experience.

[0056] It can be understood that there can be multiple connecting members 70, and the multiple connecting members 70 can be symmetrically or asymmetrically arranged. Of course, the embodiment of the utility model is not limited to this.

[0057] Please continue to refer to Figure 1-Figure 3In some embodiments, the first adjusting member 20 is provided with a first adjusting rack 23, the second adjusting member 30 is provided with a second adjusting rack 33, and the near-eye display device 100 further includes a gear knob 80, which is disposed between the first adjusting rack 23 and the second adjusting rack 33, and the gear knob 80 is used to drive the first adjusting rack 23 and the second adjusting rack 33 in the second direction (such as Figure 2 The first fixing member 40 and the second fixing member 50 move in the second direction, thereby adjusting the positions of the left lens a and the right lens b. The second direction is perpendicular to the first direction.

[0058] It should be noted that, under ideal conditions, the center of the image projected by the near-eye display device 100 should be directly in front of the center of the human eye's pupil to obtain the best visual effect. However, the pupil distance of the human eye is not fixed, and different people may have different pupil distances. If the pupil distance of the near-eye display device 100 is fixed, the center of the human eye's pupil and the center of the image will not be in a straight line, resulting in poor visual effects, unclear pictures, and affected user experience.

[0059] Therefore, by setting a first adjustment rack 23 on the first adjusting member 20 and a second adjustment rack 33 on the second adjusting member 30, rotating the gear knob 80 can drive the first adjustment rack 23 and the second rack to move in the second direction, thereby adjusting the relative position of the first adjusting member 20 and the second adjusting member 30, the first adjusting member 20 can drive the first fixing member 40 to move in the second direction, and the second adjusting member 30 can drive the second fixing member 50 to move in the second direction, thereby adjusting the relative position of the first fixing member 40 and the second fixing member 50, and finally adjusting the position of the left lens a and the right lens b so that the center of the human eye pupil is aligned with the center of the image, thereby improving the imaging quality of the near-eye display device 100 and further improving the user experience.

[0060] Please continue to refer to Figure 1-Figure 3 In some optional embodiments, a second through hole 64 is provided on the cross beam 60, and the gear knob 80 includes a gear portion 81 and a knob portion 82. The gear portion 81 is engaged between the first adjustment rack 23 and the second adjustment rack 33, and the knob portion 82 extends out of the cross beam 60 through the second through hole 64. Rotating the knob portion 82 can drive the gear portion 81 to rotate. Thus, the knob portion 82 can adjust the relative position of the first adjustment member 20 and the second adjustment member 30, and the knob portion 82 extends out of the cross beam 60 for easy adjustment, so that the near-eye display device 100 has a simple structure and further improves the user experience.

[0061] Please continue to refer to Figure 1-Figure 3In some optional embodiments, the cross beam 60 is provided with a first positioning column 61 and a second positioning column 62, the first fixing member 40 is provided with a first positioning groove 41, and the second fixing member 50 is provided with a second positioning groove 51.
