[0038] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered as part of the specification, where appropriate.

[0039] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary, and not as a limitation. Thus, other examples of exemplary embodiments can have different values.

[0040] It should be noted that like references and characters herein relate to like items throughout the figures, and once an item is defined in one figure, it need not be discussed further in subsequent figures.

[0041] Referring to Figures 1-6 As shown, according to one embodiment of the present application, there is provided an eye cover 1, comprising a cover body 11 and a resilient portion 12, the cover body 11 having a first surface 111 and a second surface 112 disposed opposite to each other; in a working state, the first surface 111 faces a wearer, and the second surface 112 is away from the wearer;

[0042] The cover body 11 is provided with a first mounting hole 101 and a second mounting hole 102, the first mounting hole 101 and the second mounting hole 102 are spaced apart along a first direction; the first mounting hole 101 and the second mounting hole 102 are configured to mount a lens barrel of a head-mounted display device to which the eye cover is applied;

[0043] The resilient portion 12 is disposed on the cover body 11, and the resilient portion 12 is in a convex structure on one of the first surface 111 and the second surface 112, and in a concave structure on the other;

[0044] The resilient portion 12 is provided in a plurality, and a part of the resilient portion 12 is disposed corresponding to the first mounting hole 101 and is disposed intermittently around the first mounting hole 101; another part of the resilient portion 12 is disposed corresponding to the second mounting hole 102 and is disposed intermittently around the second mounting hole 102.

[0045] In the eyecup provided by the embodiment of the present application, the first mounting hole 101 and the second mounting hole 102 provided on the cup body 11 correspond to the two barrels of the head-mounted display device respectively; the first mounting hole 101 and the second mounting hole 102 are arranged at intervals along the first direction, which is the direction corresponding to the interval between the two eyes of the wearer.

[0046] When the interpupillary distance of the head-mounted display device is adjusted, the two barrels are moved closer to each other along the first direction to reduce the interpupillary distance, or the two barrels are moved away from each other along the first direction to increase the interpupillary distance.

[0047] For the eyecup provided by the embodiment of the present application, the elastic part 12 is arranged on the cup body 11, and the first surface 111 facing the wearer is in a convex structure and the second surface 112 away from the wearer is in a concave structure; or, the first surface 111 facing the wearer is in a concave structure and the second surface 112 away from the wearer is in a convex structure.

[0048] The elastic part 12 can absorb the rebound stress generated by the relative movement of the two barrels during the interpupillary distance adjustment to a certain extent, thereby reducing the rebound force of the cup body 11 when the barrels are adjusted, and avoiding the excessive rebound force to reduce the comfort of the wearer.

[0049] And, when the interpupillary distance is adjusted, the stretching force of the two barrels on the cup body 11 is mainly in the first direction, i.e. Figure 1 the left-right direction, and the stretching force of the two barrels on the cup body 11 in the up-down direction is less; therefore, the elastic part 12 is arranged intermittently around the first mounting hole 101 and the second mounting hole 102, rather than being arranged in a whole circle around the first mounting hole 101 and the second mounting hole 102, which can avoid unnecessary deformation of the cup body 11 in the up-down direction, thereby improving the structural strength of the cup body 11.

[0050] If the elastic part is arranged in a whole circle around the first mounting hole 101 and the second mounting hole 102, it is easy to cause the local stress of the cup body 11 to be too high, thereby reducing the durability of the cup body 11.

[0051] Referring to Figure 1 the a direction shown in the figure is the first direction, i.e. the left-right direction; Figure 1 the b direction shown in the figure is the up-down direction.

[0052] In actual application, the position of the intermittent arrangement of the elastic part 12 and the size of the interval can be set according to the stress needs of the cup body 11; thereby improving the ability of the cup body 11 to resist deformation during the interpupillary distance adjustment of the barrels.

[0053] Optionally, the elastic part 12 is integrally formed on the cover body 11 by injection molding. The cover body 11 is made of silica gel.

[0054] Referring to Figure 1 In one embodiment, the elastic part 12 includes two first elastic parts 121, which are in the shape of a circular arc.

[0055] The first first elastic part 121 is arranged on the side of the first mounting hole 101 close to the second mounting hole 102, and the second first elastic part 121 is arranged on the side of the second mounting hole 102 close to the first mounting hole 101.

[0056] In this specific example, the first elastic part 121 can reduce the rebound stress caused by the stretching of the cover body 11 when the two lens barrels move close to each other in the first direction. Moreover, the circular arc-shaped first elastic part 121 can more fully absorb the rebound stress.

[0057] Referring to Figure 1 In one embodiment, the first first elastic part 121 is arranged concentrically with the first mounting hole 101, and the second first elastic part 121 is arranged concentrically with the second mounting hole 102.

[0058] In this specific example, one of the first elastic parts 121 is arranged concentrically with the first mounting hole 101, and the other first elastic part 121 is arranged concentrically with the second mounting hole 102. In this way, the first elastic part 121 can more uniformly absorb the rebound stress when the two lens barrels move close to each other in the first direction.

[0059] Referring to Figure 1 In one embodiment, the length of the first first elastic part 121 is greater than or equal to one-third of the circumference of the first mounting hole 101 and less than or equal to one-half of the circumference of the first mounting hole 101.

[0060] The length of the second first elastic part 121 is greater than or equal to one-third of the circumference of the second mounting hole 102 and less than or equal to one-half of the circumference of the second mounting hole 102.

[0061] If the length of the first elastic part 121 is too short, it cannot fully absorb the rebound stress. If the length of the first elastic part 121 is too long, it can easily cause unnecessary deformation of the cover body 11 in the up-down direction.

[0062] Therefore, in this specific example, the length of the first elastic portion 121 is set to be one third to one half of the circumference of the first mounting hole 101 / second mounting hole 102, so as to avoid unnecessary deformation of the cover body 11 while ensuring that the first elastic portion 121 can sufficiently absorb the rebound stress. It can be understood that the circumference of the first mounting hole 101 is equal to the circumference of the second mounting hole 102.

[0063] Referring to Figure 1 illustrated, in one embodiment, the elastic portion 12 includes a plurality of second elastic portions 122, and a first portion of the second elastic portions 122 are arranged on the side of the first mounting hole 101 away from the second mounting hole 102, and the first portion of the second elastic portions 122 include straight elastic portions, circular elastic portions, and arc-shaped elastic portions.

[0064] A second portion of the second elastic portions 122 are arranged on the side of the second mounting hole 102 away from the first mounting hole 101, and the second portion of the second elastic portions 122 include straight elastic portions, circular elastic portions, and arc-shaped elastic portions.

[0065] In this specific example, the second elastic portions 122 can reduce the rebound stress generated by the stretching of the cover body 11 caused by the movement of the lens barrel away from each other in the first direction.

[0066] Specifically, the second elastic portions 122 are arranged in a spaced manner with the first elastic portion 121, i.e., there is a gap between the second elastic portions 122 and the first elastic portion 121. Moreover, the straight elastic portions, the circular elastic portions, and the arc-shaped elastic portions in the second elastic portions 122 are arranged in a spaced manner with each other.

[0067] The second elastic portions 122 are arranged to include elastic portions of multiple shapes, and there is a gap between elastic portions of different shapes, so as to improve the structural strength of the cover body 11 while ensuring the ability of the cover body 11 to resist deformation.

[0068] Referring to Figure 1 illustrated, in one embodiment, the elastic portion 12 includes a third elastic portion 123, and the third elastic portion 123 is arranged between the two first elastic portions 121; the third elastic portion 123 is in the shape of a V.

[0069] In this specific example, the V-shaped third elastic portion 123 is arranged between the two first elastic portions 121, and the third elastic portion 123 has a gap with the two first elastic portions 121, so as to further improve the ability of the cover body 11 to resist deformation.

[0070] Optionally, referring to Figure 5 illustrated, one third elastic portion 123 is arranged. Alternatively, referring to Figure 6As shown, the third elastic part 123 is provided in multiple, for example, three; and the multiple third elastic parts 123 are arranged at intervals.

[0071] Referring to Figure 3 , Figure 4 As shown, in one embodiment, the cross-sectional shape of the elastic part 12 is in an arch shape or a triangular shape.

[0072] In actual application, the cross-sectional shape of the elastic part 12 can be arranged according to the stress requirement of the cover body 11, for example, the cross-sectional shape of the elastic part 12 is arranged in an arch shape or a triangular shape.

[0073] In addition, in actual application, the density of the elastic part 12 and the wall thickness H of the elastic part 12 can be arranged according to the stress requirement of the cover body 11; for example, the wall thickness H of the elastic part 12 is arranged as 0.1mm-0.8mm.

[0074] Referring to Figure 1 , Figure 6 As shown, in one embodiment, the cover body 11 has a nose pad area 110, and in the working state, the position of the nose pad area 110 corresponds to the nose bridge of the wearer.

[0075] The cover body 11 is provided with a ventilation part 13 at the nose pad area 110, and the ventilation part 13 is in a recessed structure on the first surface 111 and in a protruding structure on the second surface 112; the ventilation part 13 extends in the first direction.

[0076] It can be understood that the nose pad area 110 is a recessed area on the first surface 111 of the cover body 11, so as to form an avoidance to the nose bridge of the wearer.

[0077] In this specific example, the ventilation part 13 is arranged at the nose pad area 110, and the ventilation part 13 is in a recessed structure on the first surface 111 facing the wearer, so that the nose pad area 110 will not be close to the skin of the wearer; the ventilation part 13 can guide the fresh air from the outside, so as to improve the touch feeling of the skin.

[0078] In addition, the ventilation part 13 extends in the first direction (left-right direction), that is, the ventilation part 13 is not arranged along the up-down direction, so as to avoid the influence of the ventilation part 13 on the shading performance of the cover body 11.

[0079] Optionally, the ventilation part 13 is integrally formed on the cover body 11 by injection molding.

[0080] Referring to Figure 6 As shown, in one embodiment, the shape of the ventilation part 13 is in a curved shape.

[0081] In this specific example, the shape of the vent 13 is set to be curved; for example, the curve bends and protrudes towards the area between the first mounting hole 101 and the second mounting hole 102, and the curve is symmetrically arranged with respect to the center line A between the first mounting hole 101 and the second mounting hole 102. This allows for the introduction of outside air as fully as possible without affecting the light-shielding performance of the cover body 11.

[0082] According to another embodiment of this application, a head-mounted display device is provided, the head-mounted display device including the eye mask 1 as described above.

[0083] In addition, refer to Figure 5 , Figure 6 As shown, the head-mounted display device also includes an eye mask bracket 2, which is an annular frame structure with a receiving cavity, and the eye mask 1 is embedded in the receiving cavity of the eye mask bracket 2.
