[0045] VR glasses are widely used in many fields, and you can get an immersive experience through them. With the continuous development of technology, the performance and functions of VR glasses are also constantly improving, such as higher resolution and lower latency, so that the VR experience is more realistic and immersive. However, VR glasses also have some defects when used. Since the straps of VR glasses are usually fixed, and due to the different head sizes of the wearers, people with larger heads are prone to a tight feeling, while people with smaller heads are relatively loose and cannot be fixed on the wearer's head, making it difficult to achieve balance and having a narrow scope of application.

[0046] The utility model provides a virtual reality device.

[0047] See also Figure 1 and Figure 3 In one embodiment of the present utility model, the virtual reality device comprises:

[0048] Eyeglass body 100;

[0049] Two straps 200 are provided, and the two straps 200 are respectively provided at two ends of the glasses body 100, and the ends of the two straps 200 away from the glasses body 100 are detachably connected; and

[0050] The adjustment assembly 300 includes a rotating shaft 310, a coil spring 320 and a locking structure 330. The rotating shaft 310 is rotatably disposed on the eyeglass body 100. The coil spring 320 is wound around the outer periphery of the rotating shaft 310 along a first direction. The end of the strap 200 close to the eyeglass body 100 is wound around the outer periphery of the rotating shaft 310 along a second direction. The first direction and the second direction are opposite. The locking structure 330 has a first state and a second state. In the first state, the locking structure 330 locks the rotating shaft 310 so that the rotating shaft 310 can only rotate along the second direction. In the second state, the locking structure 330 releases the rotating shaft 310.

[0051] In the technical solution of the utility model, the virtual reality device includes a glasses body 100, a strap 200 and an adjustment component 300. The glasses body 100 is used for fixing the glasses body 100 on the wearer's head by arranging the straps 200 on both sides of the glasses body 100. Specifically, the straps 200 are connected to the wearer's head by arranging an adjustment component 300 at both ends of the glasses body 100. One end of the strap 200 is wound around the outer periphery of the rotating shaft 310 along the second direction to buffer the strap 200. A coil spring 320 is further wound around the shaft 310 along the first direction, and the winding direction of the strap 200 is opposite to that of the coil spring 320. If the wearer has a large head circumference, the strap 200 can be pulled outward to rotate the shaft 310 to release the strap 200. When the shaft 310 rotates, the coil spring 320 is driven to rotate, so that the coil spring 320 accumulates elastic potential energy. At this time, the locking structure 330 is in the first state, and the shaft 310 can rotate in the second direction. When the strap 200 is pulled out to a length sufficient for the wearer to use, the locking structure 330 stops. When the strap 200 is pulled, the shaft 310 tends to rotate in the first direction due to the elastic potential energy accumulated by the coil spring 320, and the locking structure 330 in the first state can lock the shaft 310 to prevent the shaft 310 from rotating in the first direction, and retract the strap 200, thereby achieving automatic locking, improving the firmness of wearing, and facilitating the next use. If the wearer has a small head circumference, by adjusting the locking structure 330 to the second state, the shaft 310 rotates in the first direction driven by the elastic potential energy of the coil spring 320 until the strap 200 is retracted. When the length of the strap 200 is suitable for the wearer's head circumference, the locking structure 330 is adjusted to the first state to lock the rotating shaft 310, which is convenient for wearing and suitable for wearers with different head circumferences. In addition, after wearing, the locking structure 330 is set to prevent the strap 200 from freely expanding and contracting, so that the length of the strap 200 can be memorized and stored to avoid pulling the strap 200 out again next time. The structure is simple, the operation is convenient, and the application range is wide. Among them, the strap 200 is made of elastic material, which not only improves the wearing comfort, but also improves the wearing tightness.

[0052] The strap 200 may be made of elastic materials such as neoprene, spandex, nylon or polyester, but is not limited to the above materials. As long as the materials are elastic and can be stretched to improve the tightness and comfort of wearing, they can be used.

[0053] In this embodiment, if Figure 3 As shown, the first direction of winding of the coil spring 320 is counterclockwise, and the second direction of winding of the strap 200 is clockwise. The coil spring 320 is arranged at the end of the outer periphery of the rotating shaft 310. A coil spring 320 can be arranged at one end, or a coil spring 320 can be arranged at both ends. Arranging a coil spring 320 at each end can improve the stability of releasing elastic potential energy of the coil spring 320 and avoid instability of the rotating shaft 310.

[0054] In an embodiment of the utility model, the virtual reality device also includes two storage boxes 400, which are arranged at both ends of the glasses body 100, the rotating shaft 310 is rotatably arranged in the storage box 400, and the end of the strap 200 away from the glasses body 100 passes through the storage box 400 and extends outside the storage box 400.

[0055] Please refer to Figure 1 and Figure 2 A storage box 400 is fixed at both ends of the glasses body 100, and the storage box 400 is used to rotate and install the rotating shaft 310 and the locking structure 330, wherein the two ends of the rotating shaft 310 are respectively installed on the upper and lower ends of the inner wall of the storage box 400 through a bearing seat, so that the rotating shaft 310 can rotate along the storage box 400, one end of the strap 200 is wound on the rotating shaft 310, and the other end passes through the storage box 400 and is connected to the strap 200 passing through the storage box 400 on the other side of the glasses body 100 to form an encirclement, which is convenient for the wearer to wear. When the strap 200 is pulled outward, the rotating shaft 310 rotates in the storage box 400 to release the strap 200 to adjust the wearer's head circumference, which is suitable for wearers with different head circumferences.

[0056] In an embodiment of the present utility model, the locking structure 330 includes:

[0057] The ratchet wheel 331 is disposed on the outer periphery of the rotating shaft 310, and a plurality of ratchet teeth are evenly disposed on the outer periphery of the ratchet wheel 331;

A plurality of ratchet teeth are evenly arranged on the outer periphery of the ratchet 331. The ratchet teeth are inclined in a first direction. The pawl 332 is in the storage box 400, with one end rotatably connected to the inner wall of the storage box 400 and the other end facing the ratchet 331. In the first state, the other end of the pawl 332 is between two adjacent ratchet teeth. Due to the direction setting of the ratchet teeth, when the strap 200 is pulled in the second direction, the rotating shaft 310 rotates in the second direction. After the pulling of the strap 200 stops, the cooperation between the ratchet teeth and the pawl 332 makes the ratchet teeth unable to rotate in the first direction, so that the rotating shaft 310 is locked to maintain the length of the strap 200. When the strap 200 needs to be retracted, the pull rod 33 is pulled. 3. The pawl 332 rotates with one end connected to the storage box 400 as a fulcrum, so that the other end of the pawl 332 is away from the ratchet, and the pawl 332 releases the restraint on the ratchet 331 and the rotating shaft 310, so that under the elastic potential energy of the coil spring 320, the rotating shaft 310 is driven to rotate in the first direction, and then the strap 200 is tightened, and the strap 200 is locked after free extension and retraction through the ratchet 331 and the pawl 332, thereby improving the firmness of wearing. Among them, one end of the pull rod 333 is connected to the pawl 332, and the other end extends outward from the storage box 400, and a force-applying member is arranged at the other end. The force-applying member is located outside the storage box 400 and is larger than the pull rod 333 in size, so as to facilitate pulling the force-applying member to pull the pull rod 333, and also prevent the force-applying member from entering the storage box 400 so as to make it impossible to pull the pull rod 333, so as to facilitate operation.

[0061] In an embodiment of the present invention, the locking structure 330 further includes a tension spring 334 disposed in the storage box 400 and drivingly connected to the pawl 332 . The tension spring 334 drives the pawl 332 to move toward the ratchet 331 to place the locking structure 330 in the first state.

[0062] Please refer to Figure 3 The tension spring 334 is inside the storage box 400 and fixed to the inner wall of the storage box 400. The other end of the tension spring 334 is connected to the middle part of the pawl 332. One end of the pull rod 333 located inside the storage box 400 is also connected to the middle part of the pawl 332 and is located on both sides of the pawl 332. When the pull rod 333 is pulled outward, the tension spring 334 is stretched inside the storage box 400. When the length of the strap 200 does not need to be shortened, the pull rod 333 is released. Under the retraction of the tension spring 334, the pawl 332 is driven to rotate inside the storage box 400. The locking structure 330 switches to the first state. The end of the pawl 332 is located between two adjacent ratchet teeth to prevent the rotating shaft 310 from rotating in the first direction.
