Description

Technical field:

[0001] The utility model relates to a reflective head-mounted mobile phone VR glasses structure, and more specifically, to a VR glasses capable of increasing the horizontal field of view FOV, reducing screen window effect, and improving display clarity. The structure is mainly used on wide-screen mobile phones and can realize 2D, 3D and VR displays. Background technology:

[0002] The user base of PCVR and VR all-in-one machines is too small, and most application scenarios are difficult to implement. From a morphological point of view, mobile VR is a more basic and lower-threshold product. In order to simplify the structure, the 6DoF handle is cancelled and the 3DoF interaction provided by the mobile phone itself is adopted. It has obvious advantages in ease of use, popularity, and content ecology. Users only need to avoid its shortcomings in interactivity and wearability, and the difficulty of VR application implementation will be greatly reduced. As a relatively complete mobile computing terminal, the mobile phone includes basic elements such as power supply, computing power, storage, communication, display, and positioning. Therefore, the VR solution based on the mobile phone can be very simple. As long as VR glasses are added, some mild VR applications can be met. It is the most convenient way to popularize VR applications.

[0003] In the past, mobile VR gradually disappeared from the market due to defects such as Google Cardboard VR and various VR glasses boxes, such as low display resolution and obvious screen door effect, lack of technological innovation, and scarce VR content resources.

[0004] The phone of the head-mounted VR box is located on the outermost side. Figure 1 As shown in the figure, because the weight of the entire box is mainly concentrated on the mobile phone, the outward shift of the center of gravity leads to a poor wearing feeling. At present, the aspect ratio of the display screen of mainstream mobile phones has been increased from the previous 16:9 to 20:9 or even 21:9. Using the method of patent application 2023114989579, mobile VR can obtain a larger field of view width and higher display clarity at low magnification. However, the lower magnification increases the distance between the mobile phone and the VR glasses, and the further outward shift of the center of gravity will cause the wearing comfort of the head-mounted mobile phone VR to drop sharply. Summary of the invention:

[0005] The utility model discloses a reflective head-mounted mobile phone VR glasses structure, which is composed of a mobile phone frame (2), a reflector (3) and a VR lens (5) connected by a hinge (4). When in use, the mobile phone frame (2), the reflector (3) and the VR lens (5) form a stable triangular support structure, the mobile phone screen is fixed in the mobile phone frame (2) with the screen facing downward, the angle between the reflector (3) and the mobile phone screen is about 45 degrees, and the angle between the VR lens (5) and the mobile phone screen is about 90 degrees. The mobile phone is in the "brim" position of the head-mounted mobile phone VR glasses, and its center of gravity is close to the head. The distance between the mobile phone screen mirror image (11) after reflection and the VR lens (5) is large and basically parallel. The VR lens (5) has a small magnification to improve the VR display clarity, such as Figure 2 When in the storage state, the mobile phone frame (2), the reflector (3) and the VR lens (5) can be folded together, as shown. Figure 3 As shown in C, it is convenient to carry with you.

[0006] The mobile phone frame (2) is provided with a mounting interface (7), which can be used to mount and fix the reflective head-mounted mobile phone VR glasses on the brim (8) of a sun hat (12), or to be fixedly linked with a VR headband, such as Figure 4 shown.

[0007] The shielding sheet (6) is attached to the right outer side of the left lens and the left outer side of the right lens of the VR lens (5). The shielding sheet (6) defocuses, blurs, shields and isolates the left and right images displayed on the mobile phone screen (1), so that the left eye can only see the left image and the right edge of the left image is in a blurred transition state, and the right eye can only see the right image and the left edge of the right image is in a blurred transition state. The shielding sheet (6) is made of a white sheet material with scattering light transmittance, which not only shields the image but also changes with the brightness of the screen image, which is conducive to weakening the residual image in the binocular field of view.

[0008] A nose pad opening (9) is left in the middle of the connection between the reflector (3) and the VR lens (5), and a mask cushion (10) can be installed or pasted on the VR lens (5). Figure 3 B and Figure 5 As shown, the pressure of VR glasses on the face can be dispersed. Description of the drawings:

[0016] The reflective head-mounted mobile phone VR glasses disclosed by the utility model have a simple and compact structure and are easy to use. Compared with previous head-mounted mobile phone VR boxes, the center of gravity is closer to the head, and the wearing comfort and display clarity are greatly improved. Mobile phone VR has a 3DOF tracking function, which can be expanded to 6DOF through plug-ins. It is widely used in scenes such as watching movies, live broadcasts, games, 3D electronic photo albums, cultural travel, 3D video calls, visual education and training, and metaverse communities. It can solve the pain point of the difficulty in landing application scenarios due to the small user base of VR headsets. Compared with VR headsets, mobile phone VR has obvious advantages in ease of use and content ecology. It is plug-and-play, can be used for a long time, and can also make full use of fragmented time, which is conducive to the popularization of VR and metaverse applications. Specific implementation method:
