[0026] In the following description, for the purpose of explanation, lots of specific details are set forth in order to provide a comprehensive understanding of one or more embodiments. However, it is apparent that these embodiments can also be implemented without these specific details. In other examples, in order to facilitate the description of one or more embodiments, known structures and equipment are shown in the form of a block diagram.

The terms “first”, “second”, and “third” are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Furthermore, unless expressly specified and defined otherwise, the terms “mounted”, “connected”, and “jointed” should be interpreted broadly, e.g., as fixedly connected, detachably connected, or integrally connected; mechanical connected or electrically connected; and directly connected, indirectly connected through an intermediate medium, or communication of interiors of two elements. For people of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0028] FIG. 2 shows a structure of a virtual reality (VR) face mask according to embodiments of the present disclosure. As shown in FIG. 2, the VR face mask provided by the present disclosure includes a mask body with a supporting effect, and a first PU covering layer 11 arranged on a surface of the mask body to be attached close to a human face.

[0029] It should be noted that PU is polyurethane, and PU is an artificial synthetic material with the texture of genuine leather, and is very tough and durable, low in price, and easy to clean. In the actual use process, the first PU covering layer 11 is used to contact the human face, so that the comfort level for the face contact can be significantly improved, and cleaning is convenient. In addition, superfine fibers can be added to the PU, so that the toughness, air permeability, and wear resistance of the polyurethane are further strengthened.

[0030] Specifically, the mask body includes a mask bottom layer 12 arranged away from the first PU covering layer 11 and a filling layer arranged between the first PU covering layer 11 and the mask bottom layer 12. The filling layer is arranged to improve the stereoscopic impression of the whole VR face mask.

[0031] In addition, in order to reduce the weight of the whole device and the weight-bearing feeling of the user’s head on the premise of ensuring the integrity and stereoscopic impression of the formed VR face mask, a foamed filling layer can be selected as the filling layer. In addition, in order to reduce the manufacturing processes, the mask bottom layer 12 can be directly formed through a crusting process, that is, after the foamed filling layer is formed, the crust layer is formed on a surface of the foamed filling layer facing away from the first PU covering layer 11 through the crusting process; and the crust layer is used to replace the mask bottom layer 12.

[0032] In addition, in another preferred embodiment of the present disclosure, the VR face mask can be designed as a structure of double-sided PU plus a foamed layer therebetween. Specifically, the mask bottom layer 12 is set as a second PU covering layer, and the filling layer is set as a foamed filling layer. It should be noted that compared with the VR face mask with a one-sided PU structure, the VR face mask with the double-sided PU structure has further improved integrity and aesthetic property due to the use of the second PU covering layer instead of the crust layer on the premise of ensuring the stereoscopic impression and the sense of integrity.

[0033] In another aspect, in a third preferred embodiment of the present disclosure, the screen-printed PU covering can be used to manufacture the first PU covering layer 11, a cloth layer can be used to manufacture the mask bottom layer 12, and a sponge layer can be selected to manufacture the filling layer. It should be noted that the screen-printed PU covering is achieved by adding the screen printing process to the manufacturing process of the PU covering, which forms a PU covering with a screen-printed structure on the surface. Compared with the traditional PU covering, the screen-printed PU covering has a better support performance and is easier to clean.

[0034] Of course, the VR face mask manufactured with the cloth layer, the sponge layer and the screen-printed PU covering layer can not only ensure relatively strong stereoscopic impression, but also has a relatively low manufacturing cost due to the use of cloth and sponge.

[0035] In addition, in order to improve the integrity and aesthetic property of the VR face mask in the third preferred embodiment, the mask bottom layer 12 can also be set as a screen-printed PU covering layer, and in order to save the cost, the sponge layer is still selected as the filling layer.

[0036] To further explain the above-mentioned various VR face masks provided by the present disclosure, the specific structures of the above-mentioned various VR face masks are described in detail in turn below.

[0037] Specifically, for a first VR face mask with the one-sided PU structure, the manufacturing method thereof includes: preparing the first PU covering layer 11; placing the first PU covering layer 11 in a foaming mold to perform foam forming of the foamed filling layer on one side of the first PU covering layer 11; and trimming the foamed filling layer (by laser) to form the VR face mask.

[0038] Specifically, the process of preparing the first PU covering layer 11 includes: PU covering pre-press forming, baking and shaping, and finally cooling, thereby forming the first PU covering layer 11.

[0039] It should be noted that in the process of preparing the first PU covering layer 11, the stretching and positioning of the PU covering during the pre-press forming, the temperature and time for the baking and shaping, and the temperature and time for the foaming are particularly important, and directly affect the product performance of the formed first PU covering layer 11, so they need to be strictly controlled. Of course, the specific values of these parameters will be different depending on different preparation instruments and products with different structures, which will not be elaborated again.

[0040] Specifically, for the first VR face mask with the one-sided PU structure, after the foamed filling layer is formed, the crust layer is formed on a side of the foamed filling layer facing away from the first PU covering layer 11 through a crusting process, and is used as the mask bottom layer 12.

[0041] In another aspect, for the second VR face mask with the double-sided PU structure, the manufacturing method thereof includes: preparing the first PU covering layer 11 and the second PU covering layer; placing the first PU covering layer and the second PU covering layer in a foaming mold to form the foamed filling layer between the first PU covering layer and the second PU covering layer; and trimming the foamed filling layer (by laser) to form the VR face mask.

[0042] In another aspect, the manufacturing method of the VR face mask with the one-sided screen-printed PU covering layer structure includes: preparing the first PU covering layer 11; stacking the first PU covering layer 11 and the sponge layer, and performing hot-press forming; and arranging the cloth layer on a side of the formed sponge layer facing away from the first PU covering layer 11.

[0043] It should be noted that the forming of screen-printed PU can be one-time forming or multiple-time forming. For the one-time forming, a screen-printed PU layer and a sponge layer are stacked and placed in a hot-press forming mold, followed by hot pressing and pressure-holding forming, to form the first PU covering layer 11 (which is the screen-printed PU covering layer). For the multiple-time forming, firstly a screen-printed PU layer is subjected to hot-press forming, and the formed screen-printed PU layer and the sponge layer are subjected to hot-press forming together. Corresponding to the above steps, before the first PU covering layer 11 and the sponge layer are stacked and subjected to hot-press forming, preliminary hot-press forming is performed on the first PU covering layer 11.

[0044] It can be seen from the above specific embodiments that the VR face mask and the manufacturing method thereof provided by the present disclosure have at least the following advantages:

[0045] 1. whether it is one-sided PU plus foaming or double-sided PU plus foaming, better stereoscopic impression close to the design can be provided;

[0046] 2. the formed VR face mask has good integrity and aesthetic property; in addition, due to the use of PU plus the foamed layer, it is easy to adjust the hardness;

[0047] 3. compared with the existing manner of cloth plus sponge, a manner of the one-sided or double-sided screen-printed PU plus the sponge improves the cleanability of the face mask.

[0048] The VR face mask according to the present disclosure is described by way of the embodiments with reference to FIG. 1 and FIG. 2, as above. However, those skilled in the art should understand that various improvements can be made to the VR face mask provided by the present disclosure without departing from the content of the present disclosure. Therefore, the scope of protection of the present disclosure should be determined by the appended claims.
