Background Art

VR devices based on digital media technology, namely virtual reality head-mounted display devices, also known as VR head displays, VR glasses, and glasses VR, are products that utilize a combination of simulation technology, computer graphics, human-computer interface technology, multimedia technology, sensor technology, network technology, and other technologies. It is a new means of human-computer interaction created with the help of computers and the latest sensor technology.

In the prior art, the lenses of VR glasses are generally exposed. When using them, the VR glasses are too real and immersive, and the user cannot feel the external situation. The VR glasses are easily hit against objects, causing damage and scratches on the VR lenses, resulting in blurred imaging.

An existing patent (publication number: CN212647165U) discloses a VR lens protection device, in which a first lens frame and a second lens frame cooperate with a suction cup to be adsorbed on the lens of VR glasses. Through the movable structure of the elastic rod in the buffer tube and the support of the buffer spring, an effective shock-absorbing effect can be achieved. Once an object is hit, the shock-absorbing structure can weaken the impact force and protect the lens.

However, the above technical solution has certain defects. When in use, the two sponge straps installed on the side panels need to be tied to the body of the VR glasses, which is cumbersome, time-consuming and labor-intensive. At the same time, the sponge straps are easily damaged over time and lose their fixing effect. Therefore, a VR lens protection device is proposed.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

The following describes an embodiment of the utility model based on its overall structure.

A VR lens protection device, as shown in FIG1-3, includes a lens frame 100, characterized in that: the lens frame 100 includes a first lens frame 110 and a second lens frame 120 in a U shape, and the first lens frame 110 and the second lens frame 120 are both provided with side frames 200 on their sides;

The side frame 200 includes two sets of hinge shafts 250 fixedly installed on the sides of the first lens frame 110 and the second lens frame 120. The two sets of hinge shafts 250 are rotatably connected to the side panels 210. A pull rod groove 240 is opened on the inner side of the side panel 210. A pull rod 222 is penetrated by the side panel 210 at the corresponding position of the pull rod groove 240. A pull rod head 220 is fixedly installed at one end of the pull rod 222. The other end of the pull rod 222 extends to the inner cavity of the pull rod groove 240 and is covered with a tension spring 221 on the outer side. One end of the tension spring 221 is fixedly connected to one side of the inner cavity of the pull rod groove 240.

Push the side plate 210 along the side of the VR glasses and slide it until it touches the pull rod 222, and pull the pull rod head 220. This drives the pull rod 222 to compress the tension spring 221, so that the pull rod 222 is retracted into the pull rod slot 240, and the VR glasses are continued to be pushed until they stop, and the pull rod head 220 is released. Under the action of the tension spring 221, the pull rod 222 is pushed out, so that the pull rod 222 squeezes the side of the VR glasses to achieve a fixing effect.

Please refer to Figures 1 and 3 in particular. The first lens frame 110 and the second lens frame 120 are both provided with multiple groups of suction cups 130 on the rear sides of the upper and lower ends. Buffer tubes 132 are provided at the rear ends of the suction cups 130, and the number of buffer tubes 132 is consistent with that of the suction cups 130. An elastic rod 131 is movably installed inside the buffer tube 132, and the outer end surface of the elastic rod 131 is fixedly connected to the suction cups 130.

The suction cup 130 can be attached to the lens of the VR glasses to facilitate the installation of the first lens frame 110 and the second lens frame 120 .

Please refer to Figures 1 and 2 in particular. A through hole is opened inside the upper end frame of the first lens frame 110, and an upper connecting rod 141 is installed in the through hole. A thread is opened at the front end of the upper connecting rod 141. The upper connecting rod 141 extends from one end away from the thread to one side of the first lens frame 110 and is fixedly installed with a turntable 140.

Rotating the rotating disk 140 clockwise or counterclockwise can drive the upper connecting rod 141 to rotate in the same direction.

Please refer to FIG. 1 and FIG. 2 , a threaded through groove is formed at a corresponding position in the upper frame of the second lens frame 120 , and the thread formed at the front end of the upper connecting rod 141 is matched with the threaded through groove.

Rotating the turntable 140 clockwise drives the upper connecting rod 141 to rotate, so that the second lens frame 120 can be moved away from the first lens frame 110. Rotating the turntable 140 counterclockwise drives the upper connecting rod 141 to rotate, so that the second lens frame 120 can be moved closer to the first lens frame 110, thereby achieving the effect of adjusting the appropriate size to adapt to the size of the VR glasses.

Please refer to FIG. 1 and FIG. 2 , a guide post 150 is fixedly mounted on one side of the lower end of the first lens frame 110 , and the lower end of the second lens frame 120 is slidably connected to the guide post 150 .

Please refer to FIG. 1 and FIG. 2 , the inner end surface of the elastic rod 131 and the inner bottom end surface of the buffer tube 132 are connected with a spring 133 .

The suction cup 130 is attached to the lens of the VR glasses. When encountering external force impact such as collision, the elastic rod 131 squeezes the spring 133 in the buffer tube 132 to buffer the impact force, which can achieve an effective shock-absorbing effect.

When in use, the VR glasses are slid and pushed along the side of the slide rail groove 230 until they touch the pull rod 222, and the pull rod head 220 is pulled. The pull rod 222 compresses the tension spring 221, so that the pull rod 222 is retracted into the pull rod groove 240, and the VR glasses are continued to be pushed until they stop, and the pull rod head 220 is released. Under the action of the tension spring 221, the pull rod 222 is pushed out, so that the pull rod 222 squeezes the side of the VR glasses to achieve a fixing effect, and the turntable 140 is rotated to drive the upper connecting rod 141 to rotate, so that the second lens frame 120 is moved away from or close to the first lens frame 110, so that the size can be freely adjusted to adapt to VR glasses of different sizes; the suction cups 130 installed on the rear sides of the first lens frame 110 and the second lens frame 120 are adsorbed on the lenses of the VR glasses. When encountering external force impact such as collision, the elastic rod 131 squeezes the spring 133 in the buffer tube 132 to buffer the impact force, which can play an effective shock-absorbing effect.
