[0002] A VR glasses is a virtual reality head-mounted display device that uses the head-mounted display device to close a person's vision and hearing to the outside world, guiding the user to have a feeling of being in a virtual environment. Its display principle is that the left and right eye screens respectively display the images of the left and right eyes. After the human eye obtains this different information, a three-dimensional sense is generated in the mind. VR glasses are a brand-new man-machine interaction means created by means of computer and the latest sensor technology, and are products integrating multiple technologies such as simulation technology, computer graphics man-machine interface technology, multimedia technology, sensing technology, and network technology, and are often used in fields such as game entertainment, video viewing, and virtual social networking.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to the attached Figures 1-5 , a VR glasses imaging lens adjustment structure in an embodiment of the present utility model includes an outer shell 1. A lens frame 5 is rotatably connected inside the outer shell 1. A connecting member 6 is connected between the outer shell 1 and the lens frame 5. The connecting member is fixed to the inner bottom of the outer shell 1. One side of both the outer shell 1 and the lens frame 5 is arc-shaped, which is convenient for better fitting the human face contour and increasing the use comfort. The lens frame 5 is rotatably connected to the outer shell 1 through the connecting member 6. The lens frame 5 is connected with a first lens 3 and a second lens 4. The lens frame 5 is connected with an adjusting mechanism 2. By adjusting the lens angle in a timely manner through the adjusting mechanism 2, the burden on the eyes can be reduced and the eye fatigue can be reduced;

[0030] Please refer to the attached Figure 2 and 5, the adjusting mechanism 2 includes a first gear 23 and a second gear 26. Limiting grooves 24 are connected below both the first gear 23 and the second gear 26. The two limiting grooves 27 are located on both sides above the lens frame 5. The limiting grooves 24 are used to limit the first gear 23 and the second gear 26. A plurality of spaced racks 27 are fixed to the inner bottoms of the two limiting grooves 24. The two racks 27 are respectively meshed and connected with the first gear 23 and the second gear 26. The limiting grooves 24 are in a long strip U shape and their two sides are closed. The distance in the middle of the limiting grooves 24 is consistent with the distance between the first gear 23 and the second gear 26. Thus, when the first gear 23 and the second gear 26 are meshed with the two racks 27, the two racks 27 can always move linearly along the direction of the limiting grooves 24, which is beneficial to maintaining the stability and reliability of its adjustment;

[0031] First fixing members 21 are fixed to both sides of the lens frame 5. The first fixing members 21 are nested and connected with second fixing members 25. The second fixing members 25 are fixed to one side of the limiting grooves 24. Thus, when adjusting the lens angle upward, the first gear 23 and the second gear 26 are rotated synchronously in the clockwise direction. At this time, the first gear 23 and the second gear 26 are respectively meshed with the racks 27 on both sides, and the two racks 27 are pulled to move backward by the two limiting grooves 27. At the same time, the two second fixing members 25 pull the two first fixing members 21 to apply a backward pulling force. At this time, the lens frame 5, the first lens 3 and the second lens 4 can be driven to look up. On the contrary, if the lens angle is adjusted downward, the first gear 23 and the second gear 26 are rotated synchronously in the counterclockwise direction, then the lens frame 5, the first lens 3 and the second lens 4 look down.

[0032] Please refer to the appendix Figures 3-4 , the outer surface of the connecting member 6 is cylindrical. Openings 64 are provided on two opposite sides of the connecting member 6. A connecting column 61 is fixed to the bottom of the lens frame 5. The openings 64 are matched with the connecting column 61. The openings 64 are convenient for being matched and connected with the connecting column 61 when adjusting the lens angle up and down, and at the same time limit the connecting column 61 to prevent it from shifting to the left and right when adjusting up and down, maintaining the accuracy of its adjustment. And the openings 64 are in a U shape, which is convenient for increasing the fitting degree during connection.

[0033] A limiting cavity 62 is provided in the connecting member 6, and a limiting ball 63 is fixed at the bottom of the connecting column 61. The limiting ball 63 cooperates with the limiting cavity 62, and the limiting cavity 62 is used to limit the limiting ball 63. The limiting ball 63 is convenient for assisting the lens frame 5 to rotate left and right. When only the first gear 23 or the second gear 26 is rotated, there are two situations. First, when the first gear 23 is rotated clockwise or the second gear 26 is rotated counterclockwise, the lens frame 5 can drive the first lens 3 and the second lens 4 to tilt to the left. Second, when the first gear 23 is rotated counterclockwise or the second gear 26 is rotated counterclockwise, the lens frame 5 can drive the first lens 3 and the second lens 4 to tilt to the right, so that the lens angle can be adjusted in real time in multiple directions, and the adjustment is convenient, which is more conducive to meeting the user's usage needs, providing a more personalized and comfortable viewing experience, and enhancing the immersion and interactivity, so that the user can better enjoy the fun brought by the virtual world. Especially in some interactive VR applications, the user can interact with the virtual world more naturally by adjusting the lens angle, thereby improving the fun and realism of the game.

[0034] Please refer to the attached Figure 1 , connection ports are provided on both sides of the housing 1, and the upper ends of the first gear 23 and the second gear 26 are exposed through the connection ports, so that it is convenient to adjust the lens angle directly through the first gear 23 and the second gear 26. The operation is convenient and the adjustment method is relatively intuitive. The user does not need to spend more time and energy to explore how to adjust correctly, thereby enhancing the user experience.

[0035] Please refer to the attached Figure 2 One end of the first fixing member 21 and the second fixing member 25 are both semi-arc-shaped, which can avoid resistance formed in the connection section when adjusting and rotating, and the first fixing member 21 and the second fixing member 25 are both provided with a circular through hole 22, which increases the range of motion of the connection between the first fixing member 21 and the second fixing member 25, and the other end of the first fixing member 21 and the second fixing member 25 is long and has a certain thickness, which can enhance its structural strength and is not easy to be damaged, so that it is unobstructed and stable when connected, and at the same time, it is convenient for the auxiliary adjustment mechanism 2 to adjust the lens at multiple angles.

[0036] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
