VR equipment is the human-computer interaction equipment who uses the VR technique, and common VR equipment, the perception such as glasses form for example can keep apart human vision, sense of hearing to the external world, and the guide user produces the VR experience of being personally on the scene.
A typical glasses-shaped virtual reality device is shown in fig. 1, and includes a mirror body 200 and hair bands 100 symmetrically disposed on two sides of the mirror body, wherein a virtual reality optical assembly is disposed in the mirror body 200, for example, a glasses-shaped virtual reality device manufactured by using the optical assembly disclosed in US 20170017078B. When a user wears the virtual reality equipment to experience a virtual environment, the user utilizes the hair band 100 to fix the head of the user, and the screen of the virtual reality equipment is adjusted to be placed in front of eyes. When the virtual reality device generates a virtual space, a closed space needs to be formed between human eyes and a screen, and the image on the screen is weakened or unclear when the image is incident on the screen of the virtual reality device, or the visual effect of a user is influenced because ambient light irradiates on the eyes. Therefore, in order to prevent the incidence of external light, a light shield is generally installed on the mirror body of the virtual reality device.
The virtual reality device shown in fig. 1 is mounted with a light shield 300, and as can be seen from fig. 1, the light shield 300 is mounted on the side of the mirror body 200 close to the face of the user, i.e. on the inner side of the mirror body of the virtual reality device. The light shield 300 is made of elastic materials, when a user wears the virtual reality equipment, the face of the user is in contact with the light shield 300 and extrudes the light shield, the light shield 300 is extruded and deformed to fit the outline of the face of the user, and a closed space is formed between eyes of the user and a screen of the virtual reality equipment, so that the visual effect of the user is not influenced.
In the prior art, the light shield 300 is generally wide and thick in appearance, so as to reduce the light transmittance of the light shield and ensure the light shielding effect. However, the wide and thick light shield increases the weight of the virtual reality device, which may cause a sense of pressure when the user wears the virtual reality device, and if the thickness of the light shield 300 is reduced, the light shielding effect of the light shield 300 may be deteriorated. Therefore, the light shield of the prior art cannot ensure the light shielding effect of the light shield under the condition of light and thin shape.

Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example one
Fig. 2 is a schematic structural view of a composite shade fabric according to an embodiment of the present application.
The embodiment of the application provides a composite shading cloth, as shown in fig. 2, comprising a first knitting layer 111 and a second knitting layer 112;
wherein the first knitted layer 111 is composed of 3% spandex and 97% milk yarn, and the thickness of the first knitted layer 111 is 0.25 mm; the second knitted layer 112 is composed of 3% spandex and 97% milk yarn, and the thickness of the first knitted layer 111 is 0.25 mm; the first knitted layer 111 and the second knitted layer 112 are adhered together through water-based glue, and the texture of the first knitted layer 111 and the texture of the second knitted layer 112 form a certain included angle.
Spandex is a polyurethane fiber, has strong elasticity, has the stretching degree of 600 percent, can recover the original shape, has higher strength than rubber, is more breathable and is more wear-resistant. The milk fiber is prepared by degreasing liquid milk, removing water to obtain milk protein, adding softening agent, making into milk slurry, wet spinning to obtain milk protein fiber, and further spinning into woven yarn with softness, skin affinity and air permeability. The rayon is made up of natural cellulose through alkalization, ageing and yellowing to obtain soluble cellulose xanthate, dissolving in diluted alkali solution to obtain viscose, and wet spinning, and features high hydroscopicity, comfortable wearing and excellent spinnability.
In the first embodiment of the present application, the first knitted layer 111 and the second knitted layer 112 are both composed of 3% spandex and 97% milk yarn or rayon, and since milk yarn with a high proportion is used, the composite shade cloth has good flexibility and skin-friendly property, and a small amount of spandex also makes the composite shade cloth have certain elasticity; in addition, the thickness of the first knitted layer 111 and the second knitted layer 112 is 0.25mm, so that the total thickness of the composite shading cloth is only 0.5mm, and the composite shading cloth is very light and thin; moreover, the texture of the first knitted layer 111 and the texture of the second knitted layer 112 form a certain included angle, so that the texture gaps of the first knitted layer 111 and the second knitted layer 112 can be mutually covered by crossing through the included angle, thereby ensuring that the composite shading cloth has a good shading effect; therefore, the characteristics of softness, frivolity and shading have been compromise to compound shading cloth that this application embodiment one provided, and when compound shading cloth was used as the shading subassembly of virtual reality equipment, because compound shading cloth is soft and frivolous, can not cause the oppression to user's face and feel, can improve the comfort level that the user wore virtual reality equipment when guaranteeing that compound shading cloth has good shading effect. Because the flexibility of traditional shade cloth is too soft, lead to warping easily on the plasticity like this, the user warp after using many times like this and lead to the shape not good-looking, lead to the shading effect to worsen even, and the light-proofness of single-deck shade cloth is also relatively poor, combine two-layer together through aqueous adhesive, after aqueous adhesive is dry, not only increased the hardness of lens hood like this, let it be difficult for taking place to warp, the shading effect has still been improved simultaneously, let the shade cloth have certain elasticity, the shading effect and the product shape structure of lens hood have been improved greatly.

In the second embodiment of the present application, unlike the first embodiment, the thicknesses of the first knitted layer 111 and the second knitted layer 112 are increased to 0.6mm, so that the total thickness of the composite shade fabric is 1.2 mm; in the second embodiment of the present application, under the condition that the composite shading cloth is light and thin, the thicknesses of the first knitted layer 111 and the second knitted layer 112 are increased, so that the shading capability of the composite shading cloth can be further improved, and thus, the composite shading cloth can still ensure good shading performance in an environment with strong light (for example, in sunlight); when compound shading cloth is used as the shading subassembly of virtual reality equipment, because compound shading cloth is soft and frivolous, can not cause the oppression to user's face and feel, can improve the comfort level that the user wore virtual reality equipment when guaranteeing that compound shading cloth has good shading effect.
