Description

Technical Field

[0001] The utility model relates to a VR glasses and a lens module detection instrument thereof, in particular to a VR glasses tester. Background Art

[0002] Since binocular near-eye display detection needs to simulate the object distance range from 0.2 meters to infinity, with a large object distance range, the existing methods generally use industrial cameras and industrial lenses to obtain images (as Figure 7 shown). The existing VR glasses testers generally use industrial cameras and industrial lenses with relatively low pixels, and using industrial lenses cannot simulate multiple object distance ranges, generally only able to detect a specific object distance; in addition, the existing VR glasses testers cannot achieve software-controlled simulation of object distance switching, and the usage scenarios are relatively single; moreover, the existing VR glasses testers cannot adjust the binocular pupil distance and cannot adapt to the detection applications of multiple pupil distances. Therefore, inventing a VR glasses tester that can be software-controlled and electrically switch the simulated object distance can well solve the pain points of the current existing technologies and facilitate detection and production.

[0044] The lens seventeen 27 is a positive focal length lens with its convex surface facing the mirror 2 and its plane facing the image plane 6. The lens eighteen 28 is a positive focal length lens with one of its convex surfaces facing the mirror 2 and the other convex surface facing the image plane 6.

[0045] The lens nineteen 29 is a positive focal length lens with its convex surface facing the mirror 2 and its plane facing the image plane 6. The lens twenty 30 is a negative focal length lens with its convex surface facing the mirror 2 and its concave surface facing the image plane 6.

[0046] Through the above optical structure design, the entire set of lenses of the present application can be used to detect the performance of VR glasses and their lens modules, such as projection clarity and defocus, and can also implement the AA production process of VR lens modules. Moreover, the above optical design uses the mirror 2 to adjust the arrangement directions of the two lens assemblies two 3 and the shooting camera 4. The light emitted from the lens assembly one 1 enters the lens assembly two 3 after being reflected by the mirror 2 at a right angle. In this way, the lens assembly two 3 is avoided from being coaxially arranged with the lens assembly one 1, which is convenient for the combined installation of two near-eye display detection systems, and also avoids the problems of interference and insufficient operation position caused by the side-by-side arrangement of the shooting camera 4 and the lens assembly two 3. Thus, a VR glasses tester can be formed to simultaneously detect the two lenses of VR glasses.

[0047] Such as Figures 2 to 5As shown in the figure, the linear motion control component includes a stepper motor 7, a lead screw assembly, and a guide rail assembly. The second lens assembly 3 is fixed within a lens holder, and the lens holder is mounted on the guide rail assembly and connected to the lead screw assembly. The stepper motor 7 is connected to the lead screw assembly. Therefore, by driving the lead screw assembly with the stepper motor 7, the lens holder can be driven to linearly move along the guide rail in the guide rail assembly, thereby realizing a variable simulated object distance and achieving the effect of changing the simulated object distance. The lead screw assembly and the guide rail assembly in the above structure are both off-the-shelf components purchased externally, and the lens holder is also prior art. Therefore, the specific structures of the lead screw assembly and the guide rail assembly and the structure of their connection to the lens holder will not be described in detail. The mounting structure of the lens on the lens holder is also prior art and is not an improvement point of this application, so it will not be described in detail either. As a specific structure: the cavity includes a first box body 8, an intermediate box body 9, and a second box body 10. Both the first box body 8 and the second box body 10 are connected to the intermediate box body 9. The intermediate box body 9 is square, and the first box body 8 and the second box body 10 are perpendicular to each other. The first box body 8 is essentially a lens barrel. Therefore, the first lens assembly 1 is disposed within the first box body 8, and the reflecting mirror 2 is fixed within the intermediate box body 9. The fixing method of the reflecting mirror 2 is a conventional method, so it will not be described in detail. The linear motion control component and the second lens assembly 3 are disposed within the second box body 10. The shooting camera 4 is fixed to the second box body 10 by screws, and the lens of the shooting camera 4 is located within the second box body 10. Of course, the second lens assembly 3 is disposed within the second box body 10 through the lens holder, so as to realize the overall movement of the entire second lens assembly 3. The above setting method of the box body structure is also to facilitate the combined installation of two near-eye display detection systems. When it is necessary to detect the two lenses of a VR glasses, the two intermediate box bodies 9 can be fixed together by screws. In this way, the two first box bodies 8 are arranged side by side in parallel, so that the two first lens assemblies 1 can be respectively aligned with the two lenses of the VR glasses, while the second box bodies 10 are arranged in a staggered and opposite manner, which is convenient for operation and avoids the problem of interference that would occur if they were arranged side by side.

[0048] The above has introduced in detail a VR glasses tester provided by an embodiment of the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
