[0032] Example 1
[0033] like Figures 1 to 4 As shown, the VR glasses in this embodiment include a base ①, temples ②, and a flipping device ③.
[0034] Specifically, the temples ② are two in number and are connected to opposite sides of the base ① via a flipping device ③, and can be folded inward or unfolded outward respectively.
[0035] In this example, the flipping device ③ includes a first base 1, a second base 2, a rotating shaft 3, and a torque component 4. The first base 1 and the second base 2 are recessed from their inner sides outward to form a connected mounting groove c1. The rotating shaft 3 and the torque component 4 are respectively installed in the mounting groove c1. Here, the torque component is hidden to avoid exposure and improve aesthetics.
[0036] In some specific embodiments, the rotating shaft 3 is fixedly mounted on the first base 1, and the torque component 4 includes a first connecting block 41 and a second connecting block 42 respectively fixed relative to the rotating shaft 3 and the second base 2, and a spring piece 43 connected between the first connecting block 41 and the second connecting block 42. The spring piece 43 extends meanderingly between the first connecting block 41 and the second connecting block 42, and as the first base 1 and the second base 2 rotate relative to each other around the center line of the rotating shaft 3, the spring piece 43 deforms synchronously around the center line of the rotating shaft 3 and generates torque. It should be noted that the spring piece 43 extends meanderingly in the inward and outward directions.
[0037] The first connecting block 41 comprises a first block 411 extending perpendicularly around the rotating shaft 3 and formed with a notch k, a second block 412 extending radially outward from the edge of the notch k along the rotating shaft 3, wherein the first block 411 is in transition fit with the rotating shaft, and the elastic sheet 43 is fixedly connected to the second block 412 at one end. Here, the installation stability is high, and the disassembly and assembly are facilitated.
[0038] In order to facilitate implementation, the elastic sheet 43 comprises a plurality of straight sections 430 distributed side by side and at intervals, and an arc section 431 connecting between every two adjacent straight sections 430 and constituting a U shape. Each straight section 430 extends along the inner-outer direction, respectively. The first connecting block 41 and the second connecting block 42 are fixedly connected (or integrally formed) with the adjacent straight sections 430, respectively, and the included angles formed by the connected parts are all 70°-90°. In the embodiment, the number of the straight sections 430 is N, wherein N is an even number greater than 2. Every two adjacent arc sections 431 are distributed in a staggered manner in the extension direction of the straight sections 430, that is, the openings of the adjacent U shapes face in opposite directions. According to actual use requirements, the preferred value of N is 4, which can meet the torsion requirement, and the part processing is simple and the cost is low.
[0039] In addition, a guide groove c2 is further formed between the frame base 1 and the first base 1, and a guide block 20 is further formed on the second base 2 and inserted into the guide groove c2. With the turning of the temple ② relative to the frame base 1, the guide block 20 moves along the guide groove c2, and when the temple ② is in the open or folded state, the guide block 20 abuts against the inner wall of the guide groove c2. Here, the movement of the guide block is limited by the guide groove, the turning angle of the temple is controlled, and damage caused by excessive opening or folding of the temple is effectively avoided.
[0040] In summary, after adopting the turning device, the first connecting block and the second connecting block are fixed on the rotating shaft and the second base, respectively, and the elastic sheet extending in a detour is arranged between the first connecting block and the second connecting block. With the relative rotation of the first base and the second base around the center line of the rotating shaft, the elastic sheet deforms synchronously around the center line of the rotating shaft to generate torsion. Therefore, compared with the prior art, on the one hand, based on the elastic sheet extending in a detour, the deformation in the rotation direction is generated synchronously during the relative rotation of the first and second bases to form torsion, the required installation space is small, the volume of the glasses is effectively reduced, the use and storage are facilitated, and the user experience is improved. On the other hand, the structure is simple and reliable, and the processing cost is low.
