Technical Field
[0001] The utility model relates to the technical field of VR glasses, in particular to a pair of VR glasses with adjustable lens-object distance. Background Art
[0002] VR glasses are VR headsets, virtual reality head-mounted display devices. Since there was no concept of head-mounted display in the early days, VR glasses, VR goggles, VR helmets and other names were created based on their appearance. VR headsets use head-mounted display devices to block people's vision and hearing to the outside world, guiding users to have a feeling of being in a virtual environment. Its display principle is that the left and right eye screens display the images of the left and right eyes respectively. After the human eye obtains this different information, a three-dimensional sense is generated in the mind. AR is augmented reality, also known as mixed reality. It uses computer technology to apply virtual information to the real world. The real environment and virtual objects are superimposed on the same screen or space in real time and exist simultaneously. VR is virtual reality, abbreviated as VR. Its specific connotation is the technology of providing immersive feeling in a computer-generated, interactive three-dimensional environment by comprehensively utilizing computer graphics systems and various reality and control interface devices. In 1992, the report of the Interactive Systems Project Working Group funded by the National Science Foundation of the United States put forward a relatively systematic discussion of VR, and determined and suggested future research directions in the field of virtual reality environment.

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.
[0029] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.
[0030] Please refer to Figure 1-Figure 8 As shown, the utility model discloses a VR glasses with adjustable lens object distance, including a glasses body 100, wherein the glasses body 100 includes a middle shell 10, a rear shell 20, two objective lenses 30 and two objective lens adjustment assemblies 40. The two objective lenses 30 and the two objective lens adjustment assemblies 40 are both installed in the middle shell 10, the rear shell 20 is connected to the middle shell 10, and the two objective lens adjustment assemblies 40 are respectively connected to the two objective lenses 30 by transmission. The objective lenses 30 can be adjusted to move along the axis of the objective lenses 30 through the two objective lens adjustment assemblies 40, that is, the distance between the objective lenses 30 and the human eye can be adjusted.
[0031] The middle shell 10 includes two guide rail column units 11 and two slide grooves 12, wherein one guide rail column unit 11 and one slide groove 12 match one objective lens 30, and the other guide rail column unit 11 and the other slide groove 12 match another objective lens 30. The objective lens adjustment assembly 40 includes a positioning block 41 and an adjustment button 42, the objective lens 30 includes a housing 31 and a lens 32, the lens 32 is installed in the housing 31, the housing 31 includes an adjustment wall 311 extending toward the adjustment button 42, and the adjustment button 42 is slidably arranged outside the middle shell 10, for the user to slide the adjustment button 42 from the outside. The end of the adjustment wall 311 is inserted into the adjustment button 42, and the adjustment button 42 is extended out for the user to control from the outside. The guide rail column unit 11 includes at least one guide rail column 111, which is parallel to the axial direction of the objective lens 30. The positioning block 41 is fixedly connected to the adjustment wall 311 so that the positioning block 41 and the adjustment wall 311 can move synchronously along the guide rail column 111. When the adjustment button 42 is slid, the adjustment button 42 can drive the positioning block 41 and the adjustment wall 311 to translate synchronously along the axial direction of the objective lens 30. Since the adjustment wall 311 is a part of the objective lens 30, the objective lens 30 can be driven to slide along the axial direction to adjust the distance between the objective lens 30 and the human eye. The positioning block 41 includes at least one guide rail hole portion 411 for the guide rail column 111 to penetrate, and damping glue is applied on the inner wall of the guide hole portion or the outer wall of the guide rail column 111. The present application drives the adjustment wall 311 and the objective lens 30 to slide along the slide groove portion 12 by sliding the adjustment button 42 to adjust the distance between the objective lens 30 and the human eye. During the adjustment process, the positioning block 41 will also slide synchronously with the adjustment wall 311 along the guide rail column 111. Since a damping rubber is provided on the inner wall of the guide rail hole, or a damping rubber is provided on the outer wall of the guide rail column 111 (not shown in the figure), after the user adjusts the object distance, the damping rubber will play a blocking role, and the objective lens 30 will remain in place without the action of external force. Compared with the structure of the gear adjustment objective lens 30 position on the market, the present application has a simple structure and is easy to assemble. The gear adjustment is affected by the number of teeth on the gear, and its accuracy is also affected. The user of the present application can adjust the distance required by the user by slightly moving the adjustment button 42, and the minimum distance adjusted is not affected by the number of teeth on the gear.
[0032] In an optional embodiment, the middle shell 10 further includes an outer shell body portion 13 and a middle plate portion 14, the outer shell body portion 13 is a hollow member, the middle plate portion 14 is disposed in the outer shell body portion 13, and the middle plate portion 14 is disposed perpendicular to the objective lens 30, that is, the middle plate portion 14 is perpendicular to the central axis of the objective lens 30. The middle plate portion 14 includes a first through hole portion 141, and the objective lens 30 is penetrated in the first through hole portion 141.
[0033] In an optional embodiment, the eyeglass body 100 further includes a front shell 50, the rear shell 20 and the front shell 50 are both disposed in the outer shell barrel portion 13 of the middle shell 10, the rear shell 20 is mounted on one side of the middle plate portion 14, and the front shell 50 is mounted on the side of the middle plate portion 14 away from the rear shell 20. The front shell 50 is used to place the user's mobile phone, and a cavity for placing the mobile phone is formed between the front shell 50 and the outer shell barrel portion 13 of the middle shell 10, and the position of the mobile phone can be fixed by a cover.
[0034] In an optional embodiment, the front shell 50 includes a light guide structure 51, which is a speaker-like structure and includes a first hole 511, a second hole 512 and a connecting surface 513. The connecting surface 513 connects the first hole 511 and the second hole 512. The first hole 511 is arranged close to the middle plate portion 14 of the middle shell 10. The size of the first hole 511 is smaller than the size of the second hole 512. The objective lens 30 penetrates into the light guide structure 51 from the first hole 511. The light emitted by the mobile phone is guided by the light guide structure 51 to the lens 32 of the objective lens 30 to provide an immersive experience for the user.
[0035] The number of light guide structures 51 is set to two, one objective lens 30 is arranged on one light guide structure 51, and the other objective lens 30 is arranged on the other light guide structure 51. It can be understood that the light guide structure 51 can also be set to one, and both objective lenses 30 are arranged in one light guide structure 51.
[0036] The first hole 511 is a waist-shaped hole, and the length of the first hole 511 is greater than the outer diameter of the objective lens 30, so that the objective lens 30 can move left and right in the first hole 511, that is, the pupil distance of the objective lens 30 can be adjusted. The width of the slide groove portion 12 is greater than the width of the adjustment wall 311, so that the adjustment wall 311 can move along the width direction of the slide groove portion 12, and the pupil distance of the objective lens 30 is adjusted by moving the adjustment wall 311 in the width direction of the slide groove portion 12.
[0037] In this embodiment, the VR glasses further include a light shielding sheet 60, which includes a second through hole portion, which is a circular hole, and the diameter of which is the same as the size of the objective lens 30, through which the objective lens 30 passes. The edge of the first through hole portion 141 extends a raised ring 142 toward the light shielding sheet 60, and the light shielding sheet 60 is sandwiched between the front shell 50 and the raised ring 142, so that the light shielding sheet 60 cannot move along the axial direction of the objective lens 30, and can only move left and right as the objective lens 30 moves in a direction perpendicular to the objective lens 30 when the objective lens 30 is adjusted. The middle plate portion 14 protrudes a plurality of convex wall portions 143 toward the light shielding sheet 60, and the end of the convex wall portion 143 has a buckle portion 144, and a card slot portion 61 is provided on the light shielding sheet 60, and the buckle portion 144 is buckled on the card slot portion 61. The length of the slot portion 61 (i.e., the length in the axial direction perpendicular to the objective lens 30) is longer than the width of the buckle portion 144, so the buckle portion 144 can slide in the slot portion 61, that is, the light shielding sheet 60 can slide on a plane perpendicular to the central axis of the objective lens. The present application sets the first hole 511 as a waist-shaped hole, and the length of the first hole 511 is greater than the outer diameter of the objective lens 30, so the distance between the two objective lenses 30 can be adjusted, that is, the pupil distance is adjusted. The pupil distance of different users is different, and this design can match different users. Since the pupil distance needs to be adjusted, there will be a gap between the first hole 511 and the objective lens 30. By setting the light shielding sheet 60 to block light, light is prevented from being emitted from the first hole 511, further enhancing the user's immersive experience.
[0038] In this embodiment, the number of guide rail posts 111 is set to two, and the number of guide rail holes 411 is also set to two. The two guide rail posts 111 are respectively inserted into the two guide rail holes 411 on the positioning block 41. By setting two guide rail posts 111, the stability of adjusting the distance of the objective lens 30 is increased.
[0039] It should be noted that the adjustment button 42 is provided with a long hole 421, and the long hole 421 is perpendicular to the central axis of the objective lens 30 (parallel to the plane where the axes of the two objective lenses 30 are located), that is, the length direction of the long hole 421 is parallel to the width direction of the slide groove portion 12, and the length of the long hole 421 is the stroke for adjusting the pupil distance, and the length of the long hole 421 is adapted to the width of the slide groove portion 12. A slide rail groove 70 can also be provided on the outside of the middle shell 10, and the adjustment button 42 can slide along the axial direction of the objective lens 30 in the slide rail groove 70. When the adjustment button 42 slides in the slide rail groove 70, it drives the adjustment wall 311, thereby adjusting the distance between the objective lens 30 and the human eye. When the adjustment wall 311 slides in the long hole 421, the distance between the two objective lenses 30 is adjusted, that is, the pupil distance is adjusted.
[0040] The positioning block 41 also includes a perforated portion 412 and a groove strip portion 413. The perforated portion 412 is perpendicular to the plane where the axes of the two through-hole portions are located. The perforated portion 412 is arranged between the two guide rail columns 111. The adjustment wall 311 penetrates into the perforated portion 412. The groove strip portion 413 is parallel to the plane where the axes of the two through-hole portions are located. A long strip portion 312 placed in the groove strip portion 413 is also arranged on the adjustment wall 311. When adjusting the pupil distance, the end of the adjustment wall 311 slides in the long hole 421, and at the same time, the long strip portion 312 on the adjustment wall 311 slides in the groove strip portion 413, and the groove strip portion 413 is parallel to the plane where the axes of the two through-hole portions are located, that is, the groove strip portion 413 is horizontally arranged, so that when the adjustment wall 311 is moved, the lens can be driven to move in a direction equal to the groove strip portion 413 (that is, the horizontal direction), avoiding the arc movement of the lens when moving the adjustment wall 311 due to the lever principle, thereby improving the efficiency of adjusting the pupil distance and further improving the user experience.
[0041] It is understandable that the first hole 511 may also be set as a circular hole, in which case the pupil distance cannot be adjusted.
[0042] It should be noted that the VR glasses also include a strap 200, which is used to fix the VR glasses on the user's head. This part of the structure is current technology and will not be described in detail here.
[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
