DETAILED DESCRIPTION

[0039] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0040] The first implementation method:

[0041] Figure 1-12 As shown, a detachable VR glasses frame includes a head mounted display body 1, an inner lens frame 2 is slidably provided on the head mounted display body 1, a lens mounting portion 3 is connected to the head mounted display body 1, the head mounted display body 1 includes an outer lens frame 101, a VR display screen body 102 and a damping protection frame 103 are installed in the outer lens frame 101, the inner lens frame 2 includes an inner lens frame 201 inserted into the outer lens frame 101 and opposite to the damping protection frame 103, a pair of wide lenses 202 are installed at the front end of the inner lens frame 201, a head mounted bracket 203 is installed at the rear end of the inner lens frame 201, and the head mounted bracket 203 is rotatably connected to the outer lens frame 101;

[0042] A laser scanning belt 5 is installed at the lower part of one end of the inner mirror frame 201 close to the damping protection frame 103. A plurality of evenly distributed laser grating transmitters are arranged in the laser scanning belt 5. A photoelectric converter is also arranged in the laser scanning belt 5. A strip laser receiver 104 matching the laser scanning belt 5 is installed on the damping protection frame 103. A barcode scanner and a laser distance measuring sensor are integrated in the laser scanning belt 5. The laser scanning belt 5 can perform barcode scanning and laser distance measurement through the laser grating.

[0043] The strip laser receiver 104 is used to locate the position of the lens unit 4. When the laser scanning belt 5 is working, the area where the laser receiver 104 does not receive the laser is the positioning position of the lens unit 4. The optional head-mounted display body 1 can adjust the position of the VR display screen body 102 according to the positioning position of the lens unit 4, so that the VR display screen body 102 in the head-mounted display body 1 can adapt to the position of the lens unit 4 for use by different users.

[0044] A damping telescopic rod is connected between the damping protection frame 103 and the inner lens frame 201, and a reset spring is connected between the telescopic end and the fixed end of the damping telescopic rod. The maximum extension length of the damping telescopic rod and the width of the mounting hole are matched with the thickness of the lens unit 4, and the lens unit 4 slides between the damping protection frame 103 and the inner lens frame 201; after the inner lens frame 2 is pulled outward, the damping telescopic rod is stretched, and the lens unit 4 can be installed at this time. After the lens unit 4 is installed, the damping telescopic rod is reset, and the lens unit 4 can be clamped by the damping protection frame 103 and the inner lens frame 201. A damping buffer frame matching the damping protection frame 103 is provided on the inner lens frame 201.

[0045] The lens mounting part 3 includes a fixing frame 301, and a pair of mounting holes are opened on the fixing frame 301, and a fixing cover 302 covering the mounting holes is clamped on the fixing frame 301; an extension beam 303 is connected to the outer end of the fixing frame 301, and an auxiliary beam 204 is connected to one end of the head-mounted bracket 203 close to the surface of the head-mounted display body 1, and the extension beam 303 is inserted into the auxiliary beam 204, and a limiting slide groove matching the extension beam 303 is opened in the auxiliary beam 204;

[0046] A pair of lens units 4 are clamped in the lens mounting portion 3. The lens units 4 include a pair of frames 401 connected by screws. An upper slide bar 402 and a lower slide plate 403 are respectively connected at the upper and lower ends of the frame 401. A lens 404 is clamped between the pair of frames 401. An identification code bonding area is provided on the lower slide plate 403. The height of the upper slide bar 402 matches the depth of the fixed frame 301. An identification code is bonded to the identification code bonding area. The identification code includes a two-dimensional code and a bar code. When the pair of upper slide bars 402 are docked, they are in an "I" shape. After the lens unit 4 is inserted into the mounting hole, the upper slide bar 402 is located in the fixed frame 301. At this time, the user manually presses and slides the upper slide bar 402 to adjust the position of the lens unit 4 until the position of the lens unit 4 matches the pupil distance of the user.

[0047] After the lens unit 4 is installed, the head mounted display body 1 identifies the type and information of the lens unit 4, and then adjusts the settings of the VR display screen body 102 so that the display settings of the VR display screen body 102 are adapted to the lens 404;

[0048] The laser scanning belt 5 includes a laser grating device 501, and a lifting rod 502 is connected between the laser grating device 501 and the inner mirror frame 201. A through hole matching the laser grating device 501 is opened at the bottom end of the outer mirror frame 101, and the spacing between the through hole and the damping protection frame 103 matches the width of the lens unit 4. After the lens unit 4 is installed, the laser grating device 501 can be driven by the lifting rod 502 to descend to the lower side of the outer mirror frame 101. At this time, the laser grating device 501 is stuck in the through hole, and the inner mirror frame 2 is limited. The laser grating device 501 is integrated with barcode recognition and laser ranging functions.

[0049] The laser grating device 501 can be driven to rise and fall. When the laser grating device 501 is located in the inner lens frame 2, it performs a barcode recognition function, which is mainly used to recognize the identification code on the lens unit 4. After the lens unit 4 is installed, the laser grating device 501 can be lowered to the lower side of the head-mounted display body 1. At this time, the laser grating device 501 switches to a laser ranging function, which is used for laser ranging of the surrounding environment to assist the head-mounted display body 1 in detecting the surrounding environment.

[0050] The cross-sections of the fixed frame 301, the inner lens frame 201 and the damping protection frame 103 are all V-shaped, and the movable range length of the lens 404 matches the length of the wide lens 202. At this time, the laser scanning belt 5 and the strip-shaped laser receiver 104 are set as a pair of mutually spliced ​​pairs, and after splicing, they are both V-shaped matching the inner lens frame 201 and the damping protection frame 103;

[0051] The wide lens 202 includes a plain lens, and the lens 404 is a functional lens, which includes a reading lens, a myopia lens, an anti-fatigue lens, or a blue light lens.

[0052] When the lens unit 4 is not installed in the lens mounting portion 3 , the inner lens frame 201 is in contact with the damping protection frame 103 .

[0053] In the present embodiment, a modular lens unit 4 is arranged in the frame, and different users can select the lens unit 4 suitable for themselves when using VR glasses, and the pupil distance can be adjusted conveniently after the lens unit 4 is installed, so that the head mounted display body 1 can adapt to the use of different users;

[0054] When using this solution, firstly, according to the needs of the user, a suitable lens unit 4 is selected. The design of the lens unit 4 is very modular, which is convenient for replacement and installation. The lenses 404 thereon can be selected according to the needs of reading glasses, myopia glasses, anti-fatigue glasses, blue light glasses or filters, etc., to meet the visual needs of different users.

[0055] When installing the lens unit 4, the user only needs to insert the lens unit 4 into the mounting hole of the lens mounting portion 3, and then manually press and slide the upper slide bar 402 to conveniently adjust the position of the lens unit 4 until the pupil distance of the lens unit 4 matches the pupil distance of the user. This design not only simplifies the installation process, but also improves the convenience of use.

[0056] After the lens unit component 4 is installed, the head mounted display body 1 can automatically identify the type and information of the lens unit component 4 , and then adjust the display settings of the VR display screen body 102 to adapt to the characteristics of the lens 404 .

[0057] In addition, the VR glasses frame of the present solution is also equipped with a laser scanning belt 5 for assisting in identifying the identification code on the lens unit 4 and performing laser ranging of the surrounding environment. These functions not only improve the convenience of use, but also enhance the intelligence of the VR glasses.

[0058] When this solution is used, the user views the VR display screen body through the wide lens 202 and the lens 404;

[0059] In summary, the VR glasses frame of this solution has the characteristics of modular design, convenient installation and adjustment, intelligent identification and environmental perception, etc., which can meet the needs of different users and provide high-quality VR experience.

[0060] Second implementation method:

[0061] It also includes a lens positioning system disposed in the VR display screen body 102, the lens positioning system includes a processor in the VR display screen body 102, and the processor is connected to a detection module, an identification module, a control module and a data storage module;

[0062] The laser scanning belt 5 and the strip laser receiver 104 are both connected to the detection module signal, and the detection module is used for the function switching of the laser scanning belt 5 and the installation position of the positioning lens unit 4;

[0063] The identification module recognizes the identification code through the laser scanning belt 5 and the bar laser receiver 104; if the two lens units 4 are identified as being of different types, the system reports an error and prompts the user to reinstall;

[0064] The control module sets the VR display screen body 102 according to the type of the lens unit 4;

[0065] The data storage module stores information of various types of lens units 4 and corresponding display setting information of the VR display screen body 102 .

[0066] The lens positioning system of this solution realizes the functions of intelligent identification and adaptation of different lens units of VR glasses. The system uses the laser scanning belt 5 and the bar laser receiver 104 to accurately locate and identify the lens unit 4, ensuring that the lens unit 4 can be correctly installed and matched with the display settings of the VR display screen body 102.

[0067] When the lens unit 4 is installed in the VR glasses, the lens positioning system first scans the lens unit 4 through the laser scanning belt 5 to determine its installation position. At the same time, the strip laser receiver 104 receives the signal from the laser scanning belt 5 to locate the exact position of the lens unit 4.

[0068] The recognition module starts to work, and reads the identification code on the lens unit 4 through the laser scanning belt 5 and the bar laser receiver 104. The identification code contains the type of the lens unit 4 and related information. After the recognition module successfully identifies the type of the lens unit 4, the control module will make corresponding display setting adjustments to the VR display screen body 102 according to the recognition result. The display setting adjustment parameters include but are not limited to adjusting the resolution, brightness and contrast of the display screen. By adjusting the display parameter settings of the display screen to adapt to the optical characteristics of different types of lenses, it is ensured that the user can obtain the best visual experience.

[0069] The data storage module stores information of various types of lens units 4 and corresponding display setting information of the VR display screen body 102. When the lens unit 4 is replaced, the data storage module can quickly provide the required display setting information so that the VR display screen body 102 can adapt to the new lens unit in the shortest time.

[0070] It should be noted that if the system recognizes that the types of the two lens units 4 are inconsistent, the system will report an error and prompt the user to reinstall. This design ensures the consistency of the types of the lens units 4 used by both eyes, avoiding visual discomfort or other problems caused by mismatched lens types.

[0071] The lens positioning system of this embodiment improves the usability and user experience of VR glasses by intelligently identifying and adapting to the functions of different lens units 4. It enables users to easily replace lens units 4 and adjust the settings of the VR display according to their needs, thereby obtaining a more comfortable and personalized VR experience.

[0072] In summary, the present solution realizes rapid adaptation to different users by installing modular lens units 4, and the lens units are automatically configured after installation, which makes it easy to meet the needs of different users and provide a high-quality VR experience.

[0073] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
