[0040] This application proposes a face mask 10.

[0041] Please refer to Figure 1. In one embodiment of this application, the face mask 10 includes a mask body 100, a mounting bracket 200, and a plurality of support members 300. The mask body 100 forms a viewing window space 110, and one end of the mask body 100 has a contact surface 120 for conforming to the face. The mounting bracket 200 is disposed at the other end of the mask body 100 away from the contact surface 120. The plurality of support members 300 are spaced apart on the peripheral sidewalls of the mask body 100 and are disposed at the end of the mask body 100 near the mounting bracket 200. The mask body 100 is made of soft material, and the support members 300 are made of hard material.

[0042] Specifically, the mask 10 can be used in head-mounted display devices such as VR (Virtual Reality) devices and MR (Mixed Reality) devices. The mounting bracket 200 is used to connect the display device, such as VR glasses or MR glasses. When the mask 10 is worn on the user's face, the face-fitting part 120 of the mask body 100 fits against the facial area around the user's eyes and surrounds the eye area, so that the mask body 100 forms a viewing window space 110 corresponding to the user's eye area.

[0043] The main body 100 of the mask is made of soft material, which makes the face mask 120, which is in direct contact with the face, more flexible, thereby reducing the pressure of the face mask 120 on the face. At the same time, the main body 100 of the mask is lighter, which can reduce the overall weight of the mask 10 and thus improve the comfort of wearing the mask 10.

[0044] The support member 300 is made of a relatively hard material and is located near the end of the mounting bracket 200. The support member 300 has strong support capacity and can provide good support for the mask body 100 to maintain the structural stability of the mask body 100, so that the face mask 120 can apply even pressure to the user's face and make the mask 10 less likely to fall off.

[0045] In addition, multiple support members 300 are spaced around the mask body 100. The support members 300 can support the mask body 100 in multiple directions and positions, and also reduce the weight of the support members 300, thereby reducing the overall weight of the mask 10 and further improving the comfort of wearing the mask 10.

[0046] The multiple support components 300 can be the same or different in shape, size, thickness, and material. The support components 300 can be set according to different facial support needs to meet different support effects.

[0047] By configuring the mask body 100 and the support member 300 with materials of different hardness, the face-fitting 120 can provide a soft fit to the face, while the support member 300 can provide good support for the mask body 100 to ensure the stability of the mask 10 when worn. In addition, it can also reduce the overall weight of the mask 10, thereby improving the comfort of wearing the mask 10, enhancing the user experience, and strengthening the product's market competitiveness.

[0048] The technical solution of this application configures the main body 100 of the mask as a soft material and the support member 300 as a hard material, which improves the comfort of the face-fitting part 120 to the face while ensuring the support effect of the support member 300; in addition, the spaced support members 300 can reduce the weight of the support members 300, thereby reducing the overall weight of the mask 10 and improving the wearing comfort of the mask 10.

[0049] In one embodiment, the material of the cover body 100 is configured as at least one of silicone or soft thermoplastic elastomer.

[0050] Silicone and soft thermoplastic elastomers possess excellent softness and elasticity, allowing them to conform well to facial curves and provide superior wearing comfort. Simultaneously, the high elasticity of silicone and soft thermoplastic elastomers enables the face mask 120 to effectively seal against the face, reducing light entering the viewing window space 110 through gaps between the face mask 120 and facial skin, thus minimizing its impact on the visibility of the head-mounted display device. Silicone is skin-friendly, unlikely to cause allergic reactions, and can withstand prolonged contact with facial skin. The soft thermoplastic elastomer can be soft TPU (thermoplastic polyurethane elastomer), soft TPE (thermoplastic elastomer), or soft TPEE (thermoplastic polyester elastomer). The mask body 100 can be made of one of these materials, or different materials can be used in different areas of the mask body 100 to meet the different hardness requirements of the mask body 100, giving the mask body 100 good elasticity and softness. Therefore, when the mask 10 is worn on the user's face, it can adapt well to the deformation of the user's facial contours and gently conform to the user's face, thereby improving the wearing comfort of the mask 10.

[0051] In one embodiment, the support member 300 is made of at least one of carbon fiber, glass fiber, and rigid thermoplastic elastomer.

[0052] Carbon fiber has an extremely high strength-to-weight ratio, providing good structural strength and flexural strength while maintaining lightweight design. It can withstand significant deformation, helping to maintain the shape of the face mask 10. Glass fiber has high strength and rigidity, effectively enhancing the structural stability of the face mask 10. Glass fiber is also less expensive, reducing the production cost of the face mask 10. Rigid thermoplastic elastomers have high hardness and rigidity, effectively enhancing the structural stability of the face mask 10 and maintaining its shape. Rigid thermoplastic elastomers also have good impact resistance and fatigue resistance, remaining stable and less prone to breakage during long-term use. Multiple support components 300 can all be made of one of these materials, or multiple support components 300 can be made of different materials.

[0053] In one embodiment, the cover body 100 is integrally formed by a foaming process.

[0054] The mask body 100 is integrally molded using a foaming process. This can be achieved by directly foaming the raw material to conform to the structure of the mask body 100, or by first fabricating a foam sheet and then shaping it through bending, rolling, and hot pressing. By controlling the temperature, pressure, and time during the foaming process, uniform density can be achieved at different wall thicknesses to provide varying facial support, ensuring a consistent appearance while improving user comfort. The thickness and shape of the mask body 100 can be adjusted to meet different design requirements. Reducing the material density lightens the weight of the mask body 100, making it more portable. The foamed material exhibits better flexibility and resilience, better conforming to facial contours, reducing pressure points, and providing a more comfortable wearing experience. The porous structure within the foam material facilitates air circulation, reducing stuffiness inside the mask 10, especially during prolonged wear, effectively preventing sweat buildup and skin discomfort. Compared to traditional face masks 10 such as sponge or PU face masks 10, the foam material body 100 has the advantages of being easy to clean and maintain, and its resistance to alcohol friction is significantly better than that of PU face masks 10. Moreover, the entire body 100 is molded in one piece, which results in fewer processing steps, higher product yield, and lower manufacturing costs compared to traditional face masks 10.

[0055] In other embodiments, the cover body 100 can also be formed by injection molding in one piece, or by splicing multiple sheets together.

[0056] In one embodiment, referring to Figures 1 and 2, the plurality of supports 300 includes two first supports 310 distributed at both ends in the long axis direction of the viewing window space 110, the first supports 310 having a first convex arc surface protruding away from the mounting bracket 200.

[0057] The cross-section of the viewing window space 110 is approximately elliptical. Two first support members 310 are located at opposite ends of the long axis of the viewing window space 110, ensuring that both sides of the eye distribution direction are supported by the first support members 310, which helps maintain the overall shape and stability of the mask body 100. The first support member 310 protrudes away from the mounting bracket 200 and has a first convex arc surface. The first convex arc surface enhances the structural strength of the first support member 310 and improves its support effect on the mask body 100. The first convex arc surface increases the moment of inertia of the first support member 310, thereby improving its bending resistance and allowing the mask body 100 to better maintain its shape under lateral forces. The convex arc design of the first convex arc surface effectively reduces external impact forces and avoids the risk of facial injury from the sharp edges of the first support member 310 due to accidental collisions with the mask 10. When the mask 10 is subjected to external force, the first convex arc surface can disperse the stress over a larger area, reducing the damage to the structure of the mask 10 caused by concentrated stress points and extending the service life of the mask 10.

[0058] In other embodiments, the first support member 310 may also be rectangular, conical, circular or other irregular shapes.

[0059] In one embodiment, referring to Figures 1 to 3, the mounting bracket 200 has a recessed clearance space 210 on one side of the viewing window space 110 away from the contact surface 120, and the cover body 100 has a clearance opening 130 corresponding to the clearance space 210 and communicating with it; the plurality of support members 300 include a second support member 320 disposed on the opposite side of the clearance opening 130, and the second support member 320 has a second convex arc surface protruding away from the mounting bracket 200.

[0060] The clearance space 210 and clearance opening 130 are used to avoid the nose, and the edge of the clearance opening 130 is designed to fit the nose. A second support member 320 is located on the opposite side of the clearance opening 130, that is, on the other side of the minor axis of the viewing window space 110. The second support member 320 provides support to the cover body 100 on the side corresponding to the forehead, helping to further maintain the overall shape and stability of the cover body 100. The second support member 320 has a second convex arc surface that protrudes away from the mounting bracket 200. The second convex arc surface enhances the structural strength of the second support member 320 and improves its support effect on the cover body 100. The second convex arc surface increases the moment of inertia of the second support member 320, thereby improving its bending resistance and allowing the cover body 100 to better maintain its shape under lateral forces. The convex arc design of the second convex arc surface can effectively reduce external impact forces and avoid the risk of facial injury caused by the sharp edges of the second support member 320 due to accidental collisions with the mask 10. When the mask 10 is subjected to external forces, the second convex arc surface can distribute the stress over a larger area, reducing the damage to the structure of the mask 10 caused by concentrated stress points and extending the service life of the mask 10. One or more second support members 320 can be provided, with multiple second support members 320 distributed at intervals between the two first support members 310.

[0061] In other embodiments, the second support 320 may be rectangular, conical, circular, or other irregular shapes.

[0062] In one embodiment, referring to FIG2, the first convex arc surface has a first side edge 311, which extends toward the clearance opening 130 in the direction from the contact surface 120 to the mounting bracket 200, and the first side edge 311 is smoothly connected to the edge of the clearance space 210.

[0063] The first side edge 311 extends toward the clearance opening 130 in the direction from the face-contact 120 to the mounting bracket 200. The area between one end of the main body 100 of the mask and the clearance space 210 along the long axis of the viewing window space 110 is supported by the first support member 310, which provides better support for the main body 100. The first side edge 311 smoothly connects to the edge of the clearance space 210, avoiding sharp corners or abrupt seams formed by the first support member 310. This not only improves the overall structural strength of the mask 10 but also enhances the comfort of wearing the mask 10. The extended design of the first side edge 311 provides a more natural fit, reducing friction and discomfort to the facial skin.

[0064] In other embodiments, the end of the first side edge 311 near the end of the clearance space 210 is spaced from the edge of the clearance space 210.

[0065] In one embodiment, referring to FIG1, the first side edge 311 has a gap between it and the edge of the contact surface 120, and extends parallel to the edge of the contact surface 120.

[0066] A certain distance is maintained between the first side edge 311 and the edge of the face-contact 120 to ensure that they do not directly contact each other. This prevents the first side edge 311 from directly contacting the user's facial skin, reducing local pressure and significantly improving wearing comfort. It also prevents discomfort or redness caused by prolonged pressure on the skin. Furthermore, the first side edge 311 will not rub against the facial skin, further reducing potential skin irritation or damage during wear. The distance between the first side edge 311 and the edge of the face-contact 120 allows the mask 10 to better adapt to different users' facial contours, providing a more natural fit and reducing pressure points on the face. The first side edge 311 and the edge of the face-contact 120 extend parallel to each other in the direction from the face-contact 120 to the mounting bracket 200, so that the first side edge 311 and the edge of the face-contact 120 visually form a roughly parallel structure, enhancing the overall coordination and aesthetics of the mask 10. The parallel extension design also helps maintain the shape of the mask 10, preventing deformation caused by external pressure or impact, and ensuring that the mask 10 maintains a good fit throughout use.

[0067] In other embodiments, the distance between the first side edge 311 and the edge of the contact surface 120 is different in its extending direction. The shape of the first side edge 311 is different from that of the edge of the contact surface 120.

[0068] In one embodiment, referring to FIG2, the first convex arc surface also has a second side edge 312 connected to the first side edge 311. The second side edge 312 extends toward the second support member 320 in the direction from the contact surface 120 to the mounting bracket 200. The slope of the second side edge 312 is greater than the slope of the first side edge 311, and the length of the first side edge 311 is greater than the length of the second side edge 312.

[0069] The dashed line in the diagram marks the boundary between the first side edge 311 and the second side edge 312. The first convex arc surface is an arc surface protruding away from the mounting bracket 200, and also a curved surface extending towards the second support member 320 and the clearance opening 130. The second side edge 312 has a larger slope, which helps to guide external pressure and impact force, dispersing them onto the second support member 320; at the same time, it also reduces the direct contact between the second side edge 312 and the surface, lowering the possibility of friction between them. The shorter length of the second side edge 312 allows the second convex arc surface on the side containing the second side edge 312 to provide a certain degree of support and protection within a limited area. The smaller slope and greater length of the first side edge 311 allow the second convex arc surface on the side containing the first side edge 311 to provide effective support to the opposite side of the first support member 310.

[0070] In other embodiments, the first side edge 311 and the second side edge 312 may also be arranged symmetrically.

[0071] In one embodiment, please refer to FIG4, the support member 300 is provided on the outer peripheral wall of the cover body 100.

[0072] The support member 300 is located on the outer peripheral wall of the cover body 100. The support member 300 can directly withstand external pressure and impact, protecting the soft material inside the cover body 100 from damage. Because the support member 300 is located on the outer peripheral wall, it does not directly contact the user's facial skin, reducing localized pressure and friction. The soft material inside the cover body 100 can better adapt to different users' facial contours, providing a more natural fit and reducing pressure points on the face.

[0073] In other embodiments, the support member 300 is disposed on the inner peripheral wall of the cover body 100, or the support member 300 is inserted into the cover body 100.

[0074] In one embodiment, referring to FIG5, the outer peripheral wall of the cover body 100 is formed with a mounting groove 140, and the support member 300 is at least partially embedded in the mounting groove 140.

[0075] The mounting groove 140 can be a continuous annular groove or a segmented recess. The support member 300 can be partially or completely embedded in the mounting groove 140. The support member 300 being embedded in the mounting groove 140 ensures a tight fit, reduces the risk of loosening or detachment, and enhances the overall structural stability of the face mask 10. When installing the support member 300, the mounting groove 140 also serves a positioning function, allowing the support member 300 to be quickly installed in the correct position.

[0076] In one embodiment, referring to FIG5, the outer surface of the support 300 is smoothly connected to the edge of the groove of the mounting groove 140.

[0077] The outer surface of the support member 300 is smoothly connected to the edge of the mounting groove 140, forming a continuous surface without any obvious seams or steps. This makes the transition from the support member 300 to the mask body 100 natural and smooth, resulting in a flatter and smoother surface for the mask 10 and enhancing its overall harmony and aesthetics. At the same time, it also prevents the protruding support member 300 from scratching the user's hands when handling the mask 10.

[0078] In other embodiments, the outer surface of the support 300 protrudes beyond the edge of the groove of the mounting groove 140, or the edge of the groove of the mounting groove 140 protrudes beyond the outer surface of the support 300.

[0079] In one embodiment, please refer to FIG5, the mounting bracket 200 includes a mounting portion 220 and a support portion 230 protruding from the inner peripheral wall of the mounting portion 220. The cover body 100 is connected to the support portion 230, and the support member 300 is sandwiched between the cover body 100 and the inner peripheral wall of the mounting portion 220.

[0080] The mounting portion 220 is used to connect with the display device, and the support portion 230 protrudes from the inner peripheral wall of the mounting portion 220, forming a ring-shaped or segmented protruding structure. The function of the support portion 230 is to provide a support surface for the cover body 100 to connect with the mounting bracket 200, ensuring a tight connection between the cover body 100 and the mounting bracket 200. The support member 300 is sandwiched between the cover body 100 and the inner peripheral wall of the mounting portion 220, allowing the support member 300 to connect to both the cover body 100 and the mounting portion 220 simultaneously, thereby improving the stability and reliability of the overall structure of the cover 10. The support member 300 not only enhances the overall rigidity of the cover 10, but also acts as a buffer and stress disperser between the cover body 100 and the mounting portion 220, protecting the cover body 100 from external damage.

[0081] In other embodiments, the support member 300 is provided on the end face of the mounting portion 220 near the contact surface 120.

[0082] In one embodiment, the support member 300 and the mounting bracket 200 are processed separately and then fixed by adhesive bonding.

[0083] The support component 300 and the mounting bracket 200 are manufactured independently. The support component 300 can be made of rigid materials (such as carbon fiber, glass fiber, or rigid thermoplastic elastomers), while the mounting bracket 200 can be made of materials suitable for fixing and connecting (such as metal, engineering plastics, etc.). Separate manufacturing allows for precise dimensional control and surface treatment of each component, ensuring high precision and good fit during final assembly. Based on the material properties of the support component 300 and the mounting bracket 200, suitable adhesives (such as epoxy resin, polyurethane adhesive, acrylic adhesive, etc.) or double-sided tape are selected for bonding and fixing to ensure the stability of the connection between the support component 300 and the mounting bracket 200.

[0084] In one embodiment, the support member 300 and the mounting bracket 200 are integrally formed.

[0085] The support component 300 and the mounting bracket 200 are integrally molded from the same or compatible materials to ensure a tight fit between them. Manufacturing methods such as injection molding, compression molding, foaming, and CNC (Computer Numerical Control) machining can be used to complete the support component 300 and the mounting bracket 200 in a single molding process, ensuring a seamless connection between them and avoiding quality problems that may arise from bonding or assembling after separate processing. The integral molding design allows external pressure to be evenly distributed between the support component 300 and the mounting bracket 200, avoiding localized stress concentration and further improving the deformation resistance of the face mask 10.

[0086] In one embodiment, the cover body 100 is bonded and fixed to the support member 300.

[0087] The cover body 100 and the support 300 are bonded and fixed, which is simple to operate and has high assembly efficiency; it can ensure high precision and good fit between the cover body 100 and the support 300 during final assembly; it can further ensure the tight fit between the cover body 100 and the support 300, and prevent loosening or falling off.

[0088] In other embodiments, the cover body 100 and the support member 300 are formed by secondary injection molding.

[0089] In one embodiment, the cover body 100 is bonded and fixed to the mounting bracket 200.

[0090] The cover body 100 is bonded and fixed to the mounting bracket 200, which is simple to operate and has high assembly efficiency; it can ensure high precision and good fit between the cover body 100 and the mounting bracket 200 during final assembly; it can further ensure a tight fit between the cover body 100 and the mounting bracket 200, and prevent loosening or falling off.

[0091] In other embodiments, the cover body 100 and the mounting bracket 200 are formed by secondary injection molding.

[0092] In one embodiment, referring to Figures 1 and 5, the faceplate 120 is bent outward in the direction from the mounting bracket 200 to the faceplate 120.

[0093] The face mask 120 is flared, which can better adapt to the user's facial contours and provide a more natural fit. While ensuring the mask 10's light-blocking and facial support, it can also reduce the pressure of the mask 10 on the user's face, thus improving the comfort of using the mask 10.

[0094] In other embodiments, the face-fitting surface 120 is cylindrical.

[0095] In one embodiment, the cover body 100 includes a main body area and a support area, with a support member 300 disposed in the support area, and at least the wall thickness of the main body area gradually decreases in the direction from the mounting bracket 200 to the contact surface 120.

[0096] Referring to Figure 4, when the outer peripheral wall of the cover body 100 is smooth and flat, the wall thickness of the cover body 100 gradually decreases in the direction from the mounting bracket 200 to the contact surface 120. Referring to Figure 5, when the outer peripheral wall of the cover body 100 has a mounting groove 140, the wall thickness of the main body area gradually decreases in the direction from the mounting bracket 200 to the contact surface 120. The gradual decrease in wall thickness of the main body area from the mounting bracket 200 to the contact surface 120 results in a thicker wall near the mounting bracket 200 to provide a certain degree of rigidity; while the wall thickness gradually decreases near the contact surface 120 to improve flexibility and fit. Furthermore, the gradual decrease in wall thickness near the contact surface 120 makes the cover body 100 appear thinner and lighter, giving it smoother lines and improving its aesthetics, thereby enhancing the product's market competitiveness.

[0097] In other embodiments, the wall thickness of the cover body 100 as a whole is relatively uniform, or the wall thickness of the main body area is relatively uniform.

[0098] This application also proposes a head-mounted display device, which includes a mask 10. The specific structure of the mask 10 is as described in the above embodiments. Since this head-mounted display device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
