[0032] like Figures 1 to 5 As shown, the VR glasses in this embodiment include a base ①, temples ②, and a flipping device ③.

[0033] Specifically, the flipping device ③ includes a first base 1, a second base 2, a rotating shaft 3 rotatably connected between the first base 1 and the second base 2, a damping component 4, an elastic component 5, and an adjusting component 6. The first base 1 is fixedly connected to the temple ②, and the second base 2 is fixedly connected to the base ①. The damping component 4 is disposed between the first base 1 and the second base 2 and can form a resistance that hinders the relative rotation of the first base 1 and the second base 2. The elastic component 5 elastically abuts against the damping component 4. The adjusting component 6 is used to adjust the deformation of the elastic component 5. The resistance changes synchronously with the change of the elastic force formed by the elastic component 5.

[0034] In this example, the first base 1 has a sleeve portion 10, the second base 2 has connecting ears 20 located at both ends of the sleeve portion 10, and the rotating shaft 3 passes through the sleeve portion 10 and the two connecting ears 20.

[0035] The damping component 4 includes a first damping component 41 and a second damping component 42, wherein the first damping component 41 and the second damping component 42 are respectively fixed relative to the first base 1 and the second base 2 in the circumferential direction of the rotating shaft 3, and the elastic component 5 drives the first damping component 41 and the second damping component 42 to abut against each other in the axial direction of the rotating shaft 3.

[0036] In some embodiments, the first damping member 41 is sleeved on the rotating shaft 3, the sleeve part 10 is sleeved on the first damping member 41, and the elastic component 5 is installed inside the sleeve part 10 and abuts against the first damping member 41; the second damping member 42 is integrally formed on the inner wall of the connecting lug 20 close to the first damping member 41.

[0037] In order to facilitate implementation, the first damping member 41 has a plurality of first protruding parts 410 distributed in the circumferential direction of the rotating shaft 3, and the second damping member 42 has a plurality of second protruding parts 420 distributed in the circumferential direction of the rotating shaft 3, wherein the plurality of first protruding parts 410 and the plurality of second protruding parts 420 are staggered and correspond to each other in the circumferential direction of the rotating shaft 3. In this embodiment, two first protruding parts 410 and two second protruding parts 420 are provided respectively.

[0038] In some embodiments, the second protruding part 420 is formed with a guide surface m extending in the axial direction of the rotating shaft 3, the corresponding first protruding part 410 abuts against the guide surface m, and as the first base 1 and the second base 2 rotate relative to each other, the first protruding part 410 moves along the guide surface m, the first damping member 41 and the second damping member 42 move closer to or away from each other, and the elastic force formed by the elastic component 5 synchronously decreases or increases. Here, by providing the guide surface, the damping can gradually increase or decrease during the relative opening or closing of the first base and the second base, not only preventing damage caused by excessive force when opening, but also saving more effort when closing, and furthermore, it is beneficial to improve the texture and improve the user experience.

[0039] In this example, the elastic component 5 is a spring, and the elastic component 5 is sleeved on the rotating shaft 3 and forms abutting ends and moving ends abutting against the first damping member 41 from both ends; the adjusting component 6 drives the moving ends to reciprocate along the axial direction of the rotating shaft 3 to compress or release the elastic component.

[0040] In this example, the connecting lug 20 close to the moving end is formed with an adjusting channel 200; the adjusting component 6 includes an adjusting knob 60 fixedly arranged at one end of the rotating shaft 3 and an adjusting block 61 arranged in the adjusting channel 200 and threadedly matched with the rotating shaft 3, wherein the moving end abuts against the adjusting block 61, and rotating the adjusting knob 60 drives the rotating shaft 3 to rotate around its center line, and the adjusting block 61 moves synchronously along the axial direction of the rotating shaft 3. Here, based on the threadedly matched adjusting block and the rotating shaft, the adjusting knob is rotated to drive the rotating shaft to rotate to realize the movement of the adjusting block (the principle is similar to that of a lead screw drive), which has high adjustment accuracy and is easy and labor-saving to operate.

[0041] In order to further facilitate implementation, the inner wall of the adjusting channel 200 is spliced by an arc surface and a plane, and the adjusting block 61 is fitted with the inner wall of the adjusting channel 200. Here, the adjusting block is prevented from rotating.

[0042] Furthermore, the end of the rotating shaft 3 furthest from the adjustment knob 60 extends out to form a corresponding connecting ear 20 and a circumferentially oriented annular groove 30. The outer wall of the connecting ear 20 is provided with a limiting card p sleeved on the rotating shaft 3, wherein the limiting card p has multiple limiting ends p0 arranged in a ring and correspondingly inserted into the groove. Here, the assembly precision is high, the structure is compact, and the stability is strong.

[0043] In summary, by adopting this flipping device, the damping component forms a resistance that prevents the relative rotation of the first base and the second base. Then, during use, the deformation of the elastic component is adjusted by adjusting the component to adjust the elastic force applied by the elastic component to the damping component, thereby adjusting the resistance and changing the tightness of the glasses. Therefore, compared with the prior art, this utility model has several advantages. First, it is based on the elastic component elastically contacting the damping component, and adjusting the deformation of the elastic component to adjust the resistance formed by the damping component, thus flexibly meeting the adjustment needs of different users for the tightness of the glasses, making it highly practical. Second, it is simple and convenient to operate, effectively improving the user experience. Third, by setting a guide surface, the damping can gradually increase or decrease during the relative opening or closing of the first base and the second base, which not only prevents damage caused by excessive force when opening, but also makes it easier to close, and also improves the texture and user experience. Fourth, based on the threaded engagement between the adjusting block and the rotating shaft, the movement of the adjusting block is achieved by rotating the adjusting knob to drive the rotating shaft (the principle is similar to a lead screw drive), which has high adjustment accuracy and is convenient and labor-saving to operate. Fifth, it has high assembly accuracy, a compact structure, and strong stability.

[0044] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
