[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-3 In this embodiment, a VR glasses includes a head display device 1 and a fixing strap 2. A protective plate 3 is provided on the front side of the head display device 1, and an angle adjustment mechanism 4 is provided on the outer surface of the protective plate 3.

[0023] VR glasses, also known as virtual reality head-mounted displays, guide users to feel like they are in a virtual environment by displaying images on the left and right eye screens respectively. However, most VR glasses currently on the market do not have a protective structure. When used in places with strong light, the image will not be clear, affecting the experience. At the same time, it is easy to accumulate dust and be scratched when not in use, affecting the performance and life of the device. Therefore, by setting a protective plate 3, light blocking, dust prevention and scratch prevention can be achieved, which not only avoids strong light affecting the image clarity during use, but also protects the head display device 2 when not in use. By setting an angle adjustment mechanism 4, the rotation of the protective plate 3 can be limited so that the protective plate 3 can be stably located at the required angle.

[0024] The angle adjustment mechanism 4 includes a cylinder 401, which is fixedly mounted on the top front side of the head display device 1 body. A rotating rod 402 is rotatably mounted between the left and right inner walls of the cylinder 401. Two connecting rods 403 are fixedly mounted on the outer surface of the rotating rod 402. A gear 404 is fixedly mounted in the middle of the rotating rod 402, and a limiting device is provided at the bottom of the gear 404.

[0025] The limiting device includes a block 405, a block 405 is provided at the bottom of the gear 404, two vertical plates 406 are fixedly installed on the inner bottom wall of the cylinder 401, and a sliding groove 407 is provided on the opposite side of the two vertical plates 406. Sliders 408 are slidably installed inside the two sliding grooves 407, and a spring 409 connected to the block 405 is fixedly installed on the inner bottom wall of the cylinder 401.

[0026] When in use, first flip the protective plate 3 upward and adjust the protective plate 3 to a suitable light-blocking angle. When the protective plate 3 rotates, it drives the two connecting rods 403 to rotate, and the two connecting rods 403 drive the rotating rod 402 to rotate, and the rotating rod 402 drives the gear 404 to rotate. During the rotation of the gear 404, the card block 405 is squeezed, and under the contraction of the spring 1 409, the card block 405 passes through the two sliders 408 and slides downward in the slide groove 407. After the protective plate 3 is adjusted to a suitable angle, the protective plate 3 is no longer rotated, and the spring 1 409 expands, pushing the card block 405 to move upward back to its original position and get stuck on the tooth groove of the gear 404, limiting the rotation of the gear 404, that is, limiting the protective plate 3.

[0027] When not in use, the protective plate 3 can be flipped downward so that the entire protective plate 3 is located in front of the head-mounted display device 1, and the magnetic block 1 and the magnetic block 2 are attracted and fit together to stably fix the protective plate 3 on the head-mounted display device 1.

[0028] The protective plate 3 is made of polycarbonate, which is lightweight, dustproof, scratch-resistant and light-blocking. It can meet the usage requirements in various scenarios and reduce the overall weight of VR glasses.

[0029] The detachable component 5 includes a housing 501 , a fixing block 502 , a fixing slot 503 , a movable block 504 , a second spring 505 , a fixing hook 506 and a pull rod.

[0030] When the protective plate 3 and the angle adjustment mechanism 4 need to be removed, first pull the two pull rods in opposite directions. The two pull rods drive the two movable blocks 504 to slide relative to each other inside the shell 501 and compress the second spring 505, so that the two movable blocks 504 drive the two fixed hooks 506 to move relative to each other. Pull the cylinder 401 downward to separate it from the fixed block 502 to achieve disassembly. When installing, loosen the two pull rods and use the expansion of the second spring 505 to make the two fixed hooks 506 fit into the inside of the fixing groove 503, so that the protective plate 3 and the angle adjustment mechanism 4 can be fixed on the head display device 1.

[0031] In summary, the VR glasses, by providing a protective plate 3, can play the role of blocking light and preventing dust and scratches. When used in places with strong light, the angle of the protective plate 3 is adjusted and locked through the angle adjustment mechanism 4, so that the protective plate 3 can be rotated to a certain angle to block light. When not in use, the protective plate 3 is covered on the front side of the head display device 1 to protect it.

[0032] Furthermore, by providing a detachable component 5, the angle adjustment mechanism 4 and the protective plate 3 can be installed and disassembled according to usage requirements, which is flexible and convenient to use.
