Abstract
Description
Technical Field
[0001] The present invention relates to the field of intelligent devices, and in particular to a mask for a head-mounted display device and a head-mounted display device having the mask. Background Art
[0002] A general head mounted display device will be provided with a shading mask, for example, the mask is installed on the rear side of the display body of the VR device through a magnetic attraction or a snap-on structure.
[0003] When a user wears a VR device, a shading mask is used to block ambient light to enhance the immersion of watching movies or playing games. The shading mask is usually made of plastic, and the hardness of the material itself plays a supporting role to stabilize the wearing function of the VR product.
[0004] The molding process of existing sunshade masks is relatively complicated. First, a hard bracket must be made as a support, and then a soft material is attached to the surface of the hard bracket for contact with the facial skin. The hard bracket itself can achieve the functions of support and light shielding, and the attached soft material is used to increase the softness of the touch. When attaching the soft material, it is necessary to manually or automatically attach it with tooling, and it is necessary to ensure that the error of the attachment position is small. Some soft materials are bonded by colloids, so the amount of colloid extrusion needs to be controlled during assembly, and attention should be paid to the fluidity of the colloid to prevent the colloid from overflowing the attachment position. This results in high overall process material costs and complex processes for the mask. Summary of the invention
[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a mask for a head mounted display device, which is used for shading, can provide support and improve the softness of touch, and the overall processing method is relatively simple and the cost is controllable.

[0007] According to the mask of the head-mounted display device of an embodiment of the present invention, the inner support layer is relatively hard as the main support, so that the mask as a whole can be supported on the face, which plays a role in stabilizing the wearing and avoiding the mask from deforming excessively and affecting the line of sight. The outer protective layer is relatively soft, and at least part of it is placed radially outside the inner support layer, which is used to improve the softness of the outer surface of the mask and the comfort of skin touch. Moreover, when the mask is subjected to external impact and bump, the outer protective layer can play a buffering and protective role. An airflow channel is formed between the outer protective layer and the inner support layer, which plays a protective role as another buffer layer. Moreover, the existence of the airflow channel gives the outer protective layer a certain deformation space, which can further improve the softness and comfort. When a through hole connecting the airflow channel is provided on a product provided with a mask, this structure can also be used to improve the air permeability of the mask, effectively solve the problem of stuffiness, and relieve the wearing pressure. By connecting the inner support layer and the outer protective layer and forming an integrally formed part, it is beneficial to reduce costs, control weight, and reduce the wearing load.

[0018] In some embodiments, the inner support layer includes: an inner panel, which is annular or semi-annular and is arranged around the eye area; and support ribs, which are arranged on the outer peripheral surface of the inner panel and toward the outer protective layer.
[0019] Specifically, there are a plurality of supporting ribs, each of which gradually shrinks in an outward direction, and an end of each supporting rib is a free end that is separable from the outer protective layer.
[0020] In some embodiments, the inner support layer and the outer protective layer are both annular, and the inner support layer and the outer protective layer are connected at the rear ends and open at the front ends.

[0043] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0044] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0045] The following describes a mask 10 of a head mounted display device according to an embodiment of the present invention with reference to the accompanying drawings.
[0046] The mask 10 of the head mounted display device according to the embodiment of the present invention is shown in FIG. Figure 1-Figure 3 , comprising: an inner support layer 1 and an outer protective layer 2. The inner support layer 1 is annular or semi-annular and is arranged around the eye region W, and the outer protective layer 2 is at least partially arranged radially outside the inner support layer 1, and an air flow channel 3 is formed between the outer protective layer 2 and the inner support layer 1. The function of the mask 10 is to surround the eye region W when worn, and the double-layer design of the mask 10 can easily ensure the light-shielding effect.
[0047] The shape of the eye region W is not limited here, and the overall shape of the mask 10 is not limited either. For example, the mask 10 as a whole can be square, round, oblong, 8-shaped, etc. When the mask 10 is 8-shaped, it can include two connected annular inner support layers 1, and the radial outer sides of the two inner support layers 1 are surrounded by an outer protective layer 2. In some solutions, the mask 10 as a whole is semi-annular, and when assembled, two masks 10 are buckled to form a whole ring, surrounding the entire eye region W.
[0048] It should be understood in the description of the present invention that the terms "inside", "outside" and the "axial", "radial", "circumferential" and other directions or positional relationships mentioned later are usually defined with reference to the eye area W. The line passing through the centroid of the eye area W and parallel to the line of sight is taken as the axis L of the eye area W, and the mask 10 as a whole is a ring or semi-ring surrounding the axis L. The direction parallel to the axis L is called the axial direction, the direction perpendicular to the axis L is called the radial direction, and the direction surrounding the axis L is called the circumferential direction. The inner support layer 1 and at least part of the outer protective layer 2 are distributed radially relative to the axis L, wherein the inner support layer 1 is on the inner side if it is close to the axis L, and at least part of the outer protective layer 2 is on the outer side if it is far from the axis L. Similarly, the circumferential surface of the inner support layer 1 is close to the axis L as its inner circumferential surface, and the circumferential surface far from the axis L as its outer circumferential surface, and the circumferential surface of the outer protective layer 2 is close to the axis L as its inner circumferential surface, and the circumferential surface of the outer protective layer 2 is close to the axis L as its inner circumferential surface, and the circumferential surface of the outer protective layer 2 is far from the axis L as its outer circumferential surface.
[0049] In addition, "upper", "lower", "front", "back", "left" and "right" are defined by the position of the mask 10 when it is worn. Among them, "front", "back", "left" and "right" are defined by the user's orientation, the user's left hand side is the left, the user's right hand side is the right, the end of the mask 10 that fits the user's face is the rear end of the mask 10, and the front end of the mask 10 is opposite to the rear end.
[0050] In the present application, the hardness of the inner support layer 1 is greater than the hardness of the outer protective layer 2, and the inner support layer 1 is connected to the outer protective layer 2 and is an integrally formed part.
[0051] Among them, the inner support layer 1 is relatively hard and serves as the main support, so that the mask 10 can be supported on the face as a whole, which plays a role in stabilizing the wearing and preventing the mask 10 from excessive deformation and affecting the line of sight.
[0052] The outer protective layer 2 is relatively soft, and at least part of the outer protective layer 2 is placed radially outside the inner supporting layer 1 to improve the outer softness and skin touch comfort of the mask 10. Moreover, when the mask 10 is subjected to external impact or collision, the outer protective layer 2 can play a buffering and protective role.
[0053] In the present application, an airflow channel 3 is formed between the outer cover layer 2 and the inner support layer 1, and the airflow channel 3 can serve as another buffer layer between the outer cover layer 2 and the inner support layer 1 to play a protective role. Moreover, the existence of the airflow channel 3 gives the outer cover layer 2 a certain deformation space, which can further improve the softness and comfort.
[0054] When a through hole 4 connected to the air flow channel 3 is provided on a product provided with a mask 10, this structure can also be used to improve the air permeability of the mask 10. Specifically, since the outer protective layer 2 is relatively soft and the outer protective layer 2 is located on the outside and is easily squeezed, the air flow in the air flow channel 3 is easily squeezed and flows. When the air in the air flow channel 3 rushes out from the through hole 4 and blows onto the user's face or body, it can take away some of the user's heat. External air flow can also be sucked into the air flow channel 3 from the through hole 4 to replenish the air volume in the air flow channel 3.
[0055] The position of the through hole 4 is not limited here, and it can be set on the inner support layer 1, on the outer protective layer 2, between the inner support layer 1 and the outer protective layer 2, or at other positions of the product provided with the mask 10. For example, a communication channel is provided in the display body 70 of the head mounted display device 100, and after the mask 10 is installed on the display body 70, the air flow channel 3 is connected to the communication channel, and the display body 70 is provided with a through hole 4, through which air can be blown toward the face.
[0056] The through hole 4 can be a hole visible to the naked eye, and the user can see the through hole 4 by observation. The through hole 4 can also be set to be smaller so that it is invisible to the naked eye. Such a setting ensures air circulation while making the mask 10 look like a whole surface without potholes that affect the visual beauty, and the through hole 4 is not easy to absorb stains.
[0057] In addition, when the through hole 4 is provided, the orientation of the through hole 4 at different positions is not restricted. When the through hole 4 is mainly used to blow toward the user, it can be directed toward the user's face (such as the forehead, cheek, eye area W), or downward toward the user's neck, shoulder, etc. When the through hole 4 is mainly used to replenish air, the position of the through hole 4 is less restricted.
[0058] It is understandable that the existing conventional masks are airtight and will cause sweating and poor comfort when worn for a long time. In the present application, by setting the airflow channel 3, when the product is provided with a through hole 4, the air in the airflow channel 3 can be blown to the user through the through hole 4 when touching the outer protective layer 2, which can promote the exchange of air inside and outside the mask 10, and make the user sweat and cool down, thereby improving the wearing comfort of the mask 10. In particular, when the through hole 4 is provided on both the inner support layer 1 and the outer protective layer 2, the eye area W surrounded by the mask 10 can form air circulation with the outside world, effectively solving the problem of stuffiness and relieving the internal pressure of the mask 10.
[0059] In the present application, the inner support layer 1 and the outer protective layer 2 are connected and formed into an integral part, and a connection structure is not required between the two, thereby reducing the number of parts, reducing the assembly process, and reducing the weight. The present application also does not require the multiple and complicated processes caused by adhesive fixation in the prior art, which is also conducive to reducing costs and controlling weight.
[0060] It is understandable that in the prior art, the mask not only has many parts and complex processes, but also its frame will use heavier plastic parts to improve the support of the mask, resulting in a heavier product itself. Wearing it for a long time will compress the cervical spine, causing dizziness and cervical fatigue. In the present application, the weight can be effectively controlled by integrally forming the inner support layer 1 and the outer protective layer 2. When the two are made of materials with lower density, the weight can be further controlled (for example, the overall weight of the mask 10 can be controlled within 60g), which can reduce the weight and relieve the pressure on the cervical spine.
[0061] In the present application, when a hole is provided on the mask 10, the type of the hole is not limited to the through hole 4 connected to the air flow channel 3, and the hole may not be connected to the air flow channel 3, or even the hole may be a blind hole provided on the surface of the mask 10. The provision of the hole can not only reduce the weight of the mask 10, but also absorb deformation when under pressure.
[0062] In some embodiments, the inner support layer 1 and the outer protective layer 2 are foamed parts formed in stages. By forming the inner support layer 1 and the outer protective layer 2 by foaming twice, the hardness of the inner foaming is increased and the outer foaming is soft, which effectively solves the problems of complex process and high cost.
[0063] Moreover, the foamed parts are used, and the material density of most of the foamed parts is relatively low, which can greatly reduce the overall weight of the mask 10, thereby reducing the sense of oppression on the human body when wearing it. The material selection range of the foamed parts is wide, and some materials can meet the requirements of toughness, strength, elastic modulus, etc. in addition to the density and hardness requirements. The material type of the foamed parts is not limited here. According to the conditions of sufficient rigidity, good toughness, low density, etc., various types of foamed parts can be selected, such as foamed plastics, foamed rubber, foamed resin, etc., specifically memory foam, latex, etc.
[0064] Of course, the structure of the inner support layer 1 and the outer protective layer 2 of the present application may not be limited thereto. For example, silicone rubber may be used, and casting in batches may increase the hardness of the inner silicone rubber and soften the outer silicone rubber.
[0065] In some embodiments, Figure 1 As shown, the outer protective layer 2 includes: an outer plate 21 and an end edge strip 22. The outer plate 21 is arranged radially outside the inner support layer 1, and the end edge strip 22 is connected to the outer plate 21 and the rear end of the inner support layer 1. In this way, the part of the mask 10 that contacts the face is relatively soft, which can further improve its skin-friendly comfort. Moreover, when the relatively soft end edge strip 22 contacts the face, it is easy to fit closely to the face, thereby further improving the light-shielding effect.
[0066] Optionally, the hardness of the edge strip 22 is lower than the hardness of the peripheral plate 21. Since the edge strip 22 in the mask 10 that contacts the face does not need to support the shape of the mask 10, further reducing the hardness of the edge strip 22 can further improve comfort and light-shielding sealing.
[0067] Specifically, the outer plate 21, the end edge strip 22, and the outer protective layer 2 are foamed and molded in stages, so that the connection reliability of the connection can be guaranteed.
[0068] In some embodiments, Figure 1-Figure 3 As shown, at least one of the inner support layer 1 and the outer protective layer 2 is provided with a through hole 4, and the through hole 4 is connected to the air flow channel 3. When the inner support layer 1 is provided with a through hole 4, the outer protective layer 2 is configured to block the through hole 4 to block light. When the outer protective layer 2 is provided with a through hole 4, the inner support layer 1 is configured to block the through hole 4 to block light. In other words, when the through hole 4 is provided on the mask 10, the inner support layer 1 and the outer protective layer 2 cooperate with each other to ensure air permeability while not affecting the light blocking effect.
[0069] It is understandable that when the aperture of the through hole 4 is relatively small, since the amount of light entering the through hole 4 is relatively small, the light can be prevented from affecting the visual effect by reasonably setting the position of the through hole 4. For example, the through hole 4 is set at the corner of the mask 10, which is easy to hide and has less light transmission, and it is easier to use the inner support layer 1 and the outer protective layer 2 for light shielding.
[0070] In some embodiments, the through hole 4 includes: an inner hole 41 and an outer hole 42 , the inner hole 41 is arranged on the inner support layer 1 , and the outer hole 42 is arranged on the outer protective layer 2 .
[0071] In some specific embodiments, the through hole 4 includes: an inner hole 41 and an outer hole 42 , and the projection of each outer hole 42 along the axis of the hole onto the inner support layer 1 avoids the adjacent inner hole 41 .
[0072] In other specific embodiments, Figure 5 As shown, the angle between the axis of each outer hole 42 and the axis of the adjacent inner hole 41 is between 30 degrees and 150 degrees.
[0073] In some other specific embodiments, the through hole 4 includes: an inner hole 41 and an outer hole 42. Not only does the projection of each outer hole 42 along the axis of the hole onto the inner support layer 1 avoid the adjacent inner hole 41, but also the angle between the axis of each outer hole 42 and the axis of the adjacent inner hole 41 is between 30 degrees and 150 degrees.
[0074] It is understandable that light propagates in a straight line from a macroscopic point of view, so in the above situation, light can be effectively blocked from entering the eye area W surrounded by the mask 10 through the outer hole 42 and the inner hole 41, effectively ensuring air permeability while ensuring light shielding.
[0075] In some specific embodiments, Figure 4As shown, when an inner hole 41 is provided on the inner support layer 1 and an outer hole 42 is provided on the outer protective layer 2, the projection of each outer hole 42 along the axis of the hole onto the inner support layer 1 avoids the adjacent inner hole 41, so that each inner hole 41 and outer hole 42 can be staggered, and the inner support layer 1 can block the light entering from the outer hole 42 without affecting the air circulation.
[0076] In some other specific embodiments, Figure 5 As shown, when an inner hole 41 is provided on the inner support layer 1 and an outer hole 42 is provided on the outer protective layer 2, a portion of the projections of the outer holes 42 along the axis of the hole may fall on the inner support layer 1 and overlap with the adjacent inner holes 41. However, since the angle between the axis of each outer hole 42 and the axis of the adjacent inner hole 41 is between 30 degrees and 150 degrees, even if light is emitted from the outer hole 42 into the inner hole 41, since the light propagates in a straight line, the light is greatly attenuated in the inner hole 41, so that the light that finally enters the eye area W is small and can be ignored.
[0077] Optionally, the angle between the axis of the outer hole 42 and the axis of the adjacent inner hole 41 is 30 degrees, 45 degrees, 50 degrees, 60 degrees, 75 degrees, 80 degrees, 85 degrees, 90 degrees, 100 degrees, 110 degrees, 125 degrees, 135 degrees, 150 degrees, etc.
[0078] Specifically, the angle between the axis of each outer hole 42 and the axis of the adjacent inner hole 41 is between 60 degrees and 120 degrees. Further, the angle between the axis of each outer hole 42 and the axis of the adjacent inner hole 41 is between 85 degrees and 95 degrees.
[0079] In some specific embodiments, Figure 6 As shown, when the inner support layer 1 is provided with inner holes 41 and the outer protective layer 2 is provided with outer holes 42, the projection of each outer hole 42 along the axis of the hole onto the inner support layer 1 avoids the adjacent inner hole 41, and the angle between the axis of each outer hole 42 and the axis of the adjacent inner hole 41 is between 30 degrees and 150 degrees. In this way, the light shielding property of the mask 10 is further improved through double protection.
[0080] In some specific embodiments, Figure 1 As shown, at least part of the outer layer holes 42 are arranged on the side of the mask 10, and the outer layer holes 42 extend upward in the inward direction. That is, the outer layer holes 42 can be located on the left side of the eye region W, and the outer layer holes 42 extend upward in the right direction. The outer layer holes 42 can be located on the right side of the eye region W, and the outer layer holes 42 extend upward in the left direction.
[0081] At least part of the inner hole 41 is provided on the side of the mask 10, and the inner hole 41 extends downward in the inward direction. That is, the inner hole 41 may be located on the left side of the eye region W, and the inner hole 41 extends downward in the right direction. The inner hole 41 may be located on the right side of the eye region W, and the inner hole 41 extends downward in the left direction.
[0082] Optionally, when a double-layer middle hole structure of inner layer holes 41 and outer layer holes 42 is provided, the double-layer holes are arranged in a staggered manner. The outer layer holes 42 are inclined upward at 45 degrees, and the inner layer holes 41 are inclined downward at 45 degrees. In this way, the axes of the adjacent inner layer holes 41 and outer layer holes 42 are generally at an angle of 90 degrees, solving the problem of both shading and heat dissipation.
[0083] Of course, the positions and orientations of the outer layer holes 42 and the inner layer holes 41 are not limited thereto. For example, the outer layer holes 42 may be disposed at the side of the mask 10, and the inner layer holes 41 may be disposed at the bottom of the mask 10.
[0084] In some specific embodiments, Figure 7 As shown, the mask 10 further includes: a flexible cover 5, at least part of which covers the outside of the outer protective layer 2, and the flexible cover 5 is a light-shielding and breathable member. The flexible cover 5 is added, and the flexible cover 5 itself is relatively light and thin, so that the overall weight of the mask 10 is not greatly increased, and the skin-friendly comfort can be improved.
[0085] In addition, the mask 10 is covered with a flexible cover 5, which helps to improve the visual aesthetics, improve the light-shielding properties, does not affect the breathability, and can improve the cleanliness of the inner support layer 1 and the outer protective layer 2.
[0086] The flexible cover 5 can be made of cloth or other flexible materials.
[0087] Specifically, Figure 7 As shown, the flexible cover 5 includes an inner sheet 51 and an outer sheet 52, wherein the inner sheet 51 covers the inner circumference of the inner support layer 1, and the outer sheet 52 covers the outer circumference of the outer protective layer 2, and the inner sheet 51 and the outer sheet 52 are connected at the rear ends and open at the front ends. In this way, it is very easy to put on the flexible cover 5 and also convenient to remove and clean it.
[0088] In some embodiments, Figure 2 and Figure 3 As shown, the inner support layer 1 includes: an inner panel 11 and supporting ribs 12. The inner panel 11 is annular or semi-annular and is arranged around the eye region W. The supporting ribs 12 are arranged on the outer peripheral surface of the inner panel 11 and are arranged toward the outer protective layer 2. The supporting ribs 12 are arranged to support the outer protective layer 2, so that the outer protective layer 2 has a certain deformation range so that air flow is generated in the air flow channel 3 when it is squeezed, but the overall shape of the mask 10 is not collapsed to affect the appearance. In addition, since the supporting ribs 12 support the outer protective layer 2, the air flow channel 3 can be prevented from being squeezed and no air flow.
[0089] Specifically, there are multiple supporting ribs 12, so that the outer sheath 2 can be supported at multiple points, thereby improving the overall support.
[0090] Furthermore, the end of the supporting rib 12 is a free end that can be separated from the outer sheath 2. That is, the end of the supporting rib 12 can contact the outer sheath 2, but does not restrict the movement of the outer sheath 2, thereby ensuring the support and improving the freedom of movement of the outer sheath 2, and facilitating the processing of the inner supporting layer 1. In particular, when the inner supporting layer 1 is a foamed part or a cast part, demoulding is convenient.
[0091] Optionally, the end of the supporting rib 12 is a free end that is separable from the outer protective layer 2, and each supporting rib 12 gradually shrinks in the outward direction, thereby ensuring the connection strength at the root of the supporting rib 12 and avoiding breakage, so that the free end can support the outer protective layer 2, but the restriction on the outer protective layer 2 is relatively small, and more space can be left for the outer protective layer 2 to deform and squeeze the air in the airflow channel 3.
[0092] Further optionally, the free end of the supporting rib 12 is a round head to reduce stress concentration. When the supporting rib 12 supports the outer protective layer 2, the freedom of the supporting rib 12 is conducive to increasing the contact surface area and improving the uniformity of the force on the contact surface.
[0093] In some embodiments, Figure 1 and Figure 2 As shown, the inner support layer 1 and the outer protective layer 2 are both annular, and the inner support layer 1 and the outer protective layer 2 are connected at the rear end and open at the front end. This can facilitate processing, and is convenient for surrounding the eye area W, so that the eye area W forms a shading area, and can also ensure the capacity of the airflow channel 3.
[0094] When the inner supporting layer 1 and the outer protective layer 2 are foamed parts or cast parts, such a structure is also convenient for demoulding.
[0095] Of course, in the present application, when properly configured, the mask 10 can also form other shapes, which are not limited here.
[0096] The head mounted display device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
[0097] According to the head mounted display device 100 of the embodiment of the present invention, Figure 8 As shown, it includes: a display body 70 and a mask 10. The mask 10 is the mask 10 of the above embodiment, and the structure of the mask 10 is not repeated here. The front end of the mask 10 is connected to the display body 70. When the user wears it, the mask 10 is used to block external light, thereby improving the immersion of viewing the picture.
[0098] Moreover, by setting up this mask 10, the inner support layer 1 is relatively hard as the main support, so that the mask 10 can be supported on the face as a whole, which plays a role in stabilizing the wearing and preventing the mask 10 from excessively deforming and affecting the line of sight. The outer protective layer 2 is relatively soft, and at least partially placed on the radially outer side of the inner support layer 1, which is used to improve the external softness of the mask 10 and the comfort of skin touch. Moreover, when the mask 10 is subjected to external impact or bump, the outer protective layer 2 can play a buffering and protective role. An airflow channel 3 is formed between the outer protective layer 2 and the inner support layer 1, which plays a protective role as another buffer layer. Moreover, the existence of the airflow channel 3 gives the outer protective layer 2 a certain deformation space, which can further improve the softness and comfort.
[0099] When the head mounted display device 100 is provided with a through hole 4 connected to the air flow channel 3, this structure can also be used to improve the air permeability of the mask 10, effectively solve the problem of stuffiness, and relieve wearing pressure.
[0100] In the present application, the inner support layer 1 and the outer protective layer 2 are connected and formed into an integral part, which is beneficial to reduce costs, control weight, and reduce the wearing load.
[0101] The structures and working principles of other components of the head mounted display device according to the embodiment of the present invention, such as the lens module and the power supply structure, are well known to ordinary technicians in the field and will not be described in detail here.
