Description
Technical Field
The application relates to the technical field of head-mounted display, in particular to a shading assembly for virtual reality equipment and the virtual reality equipment.
Background
The virtual reality technology is a technology for providing an immersive sensation in a three-dimensional environment generated on a computer, and is a combination of various technologies such as a simulation technology, computer graphics, a human-computer interface technology, a multimedia technology, a sensing technology, and a network technology. The Virtual Reality device is essentially a human-computer interaction device using a Virtual Reality technology, and common Virtual Reality devices, such as VR (Virtual Reality) glasses, can seal the senses of the user such as the vision, the hearing and the like of the outside world and guide the user to generate the sense of the user in a Virtual environment.
A typical virtual reality device is shown in fig. 23, and includes a mirror body 200 and a wearing hair band 100 symmetrically disposed on both sides of the mirror body 200, wherein a virtual reality optical assembly is disposed in the mirror body 200, and the virtual reality optical assembly includes a lens, a screen, and the like. A typical virtual reality device is, for example, one made using virtual reality optics as disclosed in US 20170017078B. When a user wears virtual reality equipment to experience a virtual environment, the hair band 100 is fixed on the head, and the screen of the virtual reality equipment is arranged in front of eyes through adjustment, and the frame of the mirror body 200 of the virtual reality equipment is attached to the face of the user. However, when wearing the virtual reality device, a gap is easily formed at a position where the frame of the mirror body 200 is attached to the face of the user, and at this time, if external light is incident on the screen of the virtual reality device through the gap, an image on the screen is weakened or unclear, or ambient light irradiates on eyes, which affects the visual effect of the user. Therefore, in order to prevent the incidence of external light, the light blocking assembly 300 is generally installed on the mirror body 200 of the virtual reality device.
A typical virtual reality device with a shutter assembly is shown in fig. 24, and includes a mirror body 200 and a shutter assembly 300, the shutter assembly 300 being mounted on a side of the mirror body 200 adjacent to the face of the user, i.e., inside the mirror body of the virtual reality device. When the glasses are worn, the shading component 300 is tightly attached to the face of a user, a closed space is formed by the shading component 300, the face of the user and the glasses body 200 of the virtual reality device, and external light cannot enter the closed space, so that the visual effect of the user cannot be influenced. In order to allow the user to experience the virtual environment for a long period of time, it is desirable to have a continuous enclosure between the shutter assembly 300, the user's face, and the mirror body 200 of the virtual reality device.
However, when the user wears the virtual reality device, the user's face will press the shade assembly 300 when contacting the shade assembly 300, and a force is applied to the shade assembly 300, which tends to move the shade assembly 300 outward (as shown by the arrow in fig. 24); moreover, the light shielding assembly 300 is only connected with the inner side of the mirror body 200 of the virtual reality device, and the installation mode is not stable, so that the light shielding assembly 300 is loosened from the mirror body 200 of the virtual reality device. Therefore, the above-mentioned situation tends to make it difficult to maintain the formed closed space for a long time. Therefore, the existing installation mode easily causes the shading component to fall off from the mirror body 200 of the virtual reality device, so that the shading component is not tightly sealed, and the use effect of the virtual reality device is influenced.

In order to facilitate the fixing of some other small electronic components of the virtual reality device, for example, the light sensor, a corresponding receiving fixing groove 114 is protruded on one side of the screen support for fixing other small electronic components. After display screen, left dust ring, screen support, right dust ring and optical module constitute and accomplish, match through the second fixed orifices that screen fixed orifices 112 on the screen support and virtual reality equipment correspond, realize that the subassembly after the equipment is fixed to virtual reality equipment on, this fixed mode is not restricted to the screw fixation mode. It should be noted that the screen fixing holes 112 of the screen support include at least one forward hole and at least one backward hole. As shown in fig. 10 to 13, the optical lens focusing assembly, which is collectively referred to as a left barrel mechanism and a right barrel mechanism, includes: the optical lens comprises an outer lens cone 211, an outer optical lens 212, an inner lens cone 214 and an inner optical lens 217, wherein the outer optical lens 212 is fixed on the outer lens cone 211, and the inner optical lens 217 is fixed on the inner lens cone 214; the side wall of the outer lens cone 211 is provided with an inclined groove 213; the inner barrel 214 is arranged in the outer barrel 211, and the side wall of the inner barrel 214 is provided with a positioning feature which also extends into the inclined groove 213 and slides along the inclined groove 213; when the inner barrel 214 slides relatively along the outer barrel 211, the distance between the outer optical lens 212 fixed on the outer barrel 211 and the inner optical lens 217 fixed on the inner barrel 214 is adjustable, thereby realizing focusing of the optical assembly.

The following description will be made for each of the above components:
(1) outer barrel 211: the outer barrel 211 has at least one inclined groove 213 formed in a sidewall thereof, the inclined groove 213 being inclined at an angle with respect to a horizontal plane, and when the positioning feature fixed to the sidewall of the inner barrel 214 is inserted into the inclined groove 213 and moved along the inclined groove 213, the distance between the outer optical lens 212 and the inner optical lens 217 is adjustable. As shown in fig. 1, the outer barrel 211 has a circular cross-sectional shape, and when the number of the inclined grooves 213 is three or more, the inclined grooves 213 are uniformly distributed in the circumferential direction of the outer barrel 211. It should be noted that the inclined grooves 213 are not limited to three as shown in the drawing, and preferably, the number of the inclined grooves 213 is three. Further, the inclined grooves 213 are not limited to being evenly distributed along the circumferential direction of the outer barrel 211, but it is necessary that a plurality of the inclined grooves 213 are located on the same horizontal plane. The sectional shape of the outer barrel 211 is also not limited to the circular shape shown in fig. 1, but may be an ellipse or a diamond or a special shape.

The light-shielding member 78 has a hollow area for accommodating the virtual reality device body, and the connection end of the light-shielding member 78 is provided with a connection opening 781 for fixedly connecting the front end fixing ring 77, and thus, the shape of the connection opening 781 is the same as the shape of the front end fixing ring 77. The end of the light shielding member 78 corresponding to the connecting end is a use end for contacting with the face of the user and forming a closed space with the face of the user.
When the shading assembly that this application provided was installed on virtual reality equipment, utilized front end fixed ring 77 parcel to live virtual reality equipment main part front end, recycled with the other positions of the virtual reality equipment of the parcel of the shading piece 78 parcel that front end fixed ring 77 is connected, the side is watched to the main part of virtual reality equipment promptly. Therefore, the front end portion of the light blocking member 78 connected to the front end fixing ring 77 is made to wrap the main body of the virtual reality apparatus, and the rear end portion of the light blocking member 78 forms a closed space with the viewing side of the virtual reality apparatus and the face of the user. Therefore, the structure of the shading assembly provided by the application is different from that of the shading assembly provided by the prior art, and the installation modes of the shading assembly and the shading assembly are also different.
The shading assembly provided by the prior art is only of a hood-shaped structure, and does not have the structure of the front end fixing ring 77 provided by the present application. During installation, one end of the shading component is connected with the watching side of the virtual reality equipment, and the other end of the shading component and the face of a user form a closed space. However, the user needs to use the virtual reality device for a long time when experiencing the virtual reality environment. When the novel shading assembly is worn, the shading assembly can be extruded when the face of a user is in contact with the shading assembly, acting force is applied to the shading assembly, the shading assembly tends to move outwards, connection between the shading assembly and the watching side of the virtual reality equipment is loosened, and the shading assembly falls off from the virtual reality equipment. This can influence the enclosure space and can not maintain for a long time, and then can not guarantee that the user can experience virtual reality environment for a long time, influences the result of use of virtual reality equipment.
And the shading subassembly that this application provided utilizes the cooperation of the solid fixed ring 77 of front end and shading piece 78, makes the structure of the main part front end of the solid fixed ring 77 of front end and virtual reality equipment mutually support, utilizes the characteristics of the two structure looks gomphosis, reaches stable connection. Adopt the mounting means who wraps up the virtual reality equipment completely, make the shading subassembly fix on the virtual reality equipment steadily, the condition that the shading subassembly easily loosens among the prior art can not appear, and then make the user when wearing the virtual reality equipment and experience virtual environment, can maintain the enclosure space for a long time, prevent that external light from disturbing user's eyes, make the user can experience the virtual reality environment better, avoid influencing user's visual effect.
In order to enable the front end fixing ring 77 to be stably fixed at the front end of the body of the virtual reality apparatus, the front end fixing ring 77 needs to have a unique structure. In this embodiment, the front end fixing ring 77 is a hollow structure, and a specific structure of the front end fixing ring 77 is illustrated with reference to fig. 27.
Specifically, the front end fixing ring 77 includes a support ring 772, and a connection ring 773 and a locking ring 774, which are respectively shaped similarly to the support ring 772. The support ring 772 is used for connecting with the shade 78 and plays a role of fixing the shade 78; the locking ring 774 is used to fix the frame 301 of the virtual reality device, playing a role of locking, and preventing the junction between the shading assembly and the virtual reality device from loosening; the connecting ring 773 is used to connect the support ring 772 and the locking ring 774, so that the front end fixing ring 77 formed by the three has a stable structure.
The support ring 772, the connecting ring 773 and the locking ring 774 have similar shapes, i.e., the three are the same shape, differing only in that they are slightly different in size. It should be noted that, the shapes of the support ring 772, the connecting ring 773 and the locking ring 774 are all similar to the outer contour shape of the main body of the virtual reality device, for example, when the front end of the main body of the virtual reality device adopts a shape corresponding to the shape of the glasses with a certain arc, the shapes of the support ring 772, the connecting ring 773 and the locking ring 774 are also preferably glasses shapes.
Since the support ring 772 is in contact with the outer edge of the virtual reality apparatus body, the size of the support ring 772 is maximized; and the locking ring 774 is in contact with the portion of the virtual reality device connected to the front shell 1, so the size of the locking ring 774 is minimal; the connecting ring 773 is used to connect the support ring 772 and the locking ring 774, and thus, the size of the connecting ring 773 is between that of the support ring 772 and that of the locking ring 774.
The connection relationship of the support ring 772, the connecting ring 773 and the locking ring 774 is shown in detail in fig. 28(a) (b).
As can be seen in fig. 28(a), the cross-sectional shape of the support ring 772 is approximately rectangular, the cross-sectional shape of the connecting ring 773 is approximately isosceles trapezoid, and the cross-sectional shape of the locking ring 774 is approximately pentagonal with two right angles.
One side 7721 of the support ring 772 is connected with one side 7732 of the connecting ring 773, i.e. the short side of the rectangle is connected with the oblique side of the isosceles trapezoid, so that the support ring 772 and the connecting ring 773 are connected in an angle, i.e. forming a support angle α 1, the other side 7731 of the connecting ring 773 is connected with one side 7742 of the locking ring 774, i.e. the other oblique side of the isosceles trapezoid is connected with the common right-angle side of the two right angles of the pentagon, so that the connecting ring 773 and the locking ring 774 are connected in an angle, i.e..
In an alternative embodiment, the outer surface 7723 of the support ring 772 is connected to the outer surface 7733 of the connecting ring 773, and the outer surface 7733 of the connecting ring 773 is connected to the outer surface 7743 of the locking ring 774, and the adjacent two may be connected by a smooth connection, so that the connection is arc-shaped, or by a direct connection, so that the connection is angular. In any connection manner, the fixed connection between the support ring 772 and the connecting ring 773, and the fixed connection between the connecting ring 773 and the locking ring 774 are not affected. The inner surface 7724 of the support ring 772 is connected with the inner surface 7734 of the connecting ring 773, and the inner surface 7734 of the connecting ring 773 is connected with the inner surface 7744 of the locking ring 774, and similarly, the connection between the inner surfaces of the adjacent two can be referred to the connection between the outer surfaces; or in actual use, the connection mode of the inner surface can refer to the structure of the front end of the main body of the virtual reality device, so that the front end fixing ring 77 is matched with the structure of the front end of the main body of the virtual reality device.
In an alternative embodiment, the connection of the inner surface 7724 of the support ring 772 and the inner surface 7734 of the connecting ring 773 and the connection of the inner surface 7734 of the connecting ring 773 and the inner surface 7744 of the locking ring 774 are described above, but the outer surface 7723 of the support ring 772 and the outer surface 7733 of the connecting ring 773 may not be connected together, and the outer surface 7733 of the connecting ring 773 and the outer surface 7743 of the locking ring 774 may not be connected together, even though the front end retainer ring 77 has an inner surface connection and an outer surface disconnection configuration. The degree of the break of the outer surfaces of the support ring 772 and the connection ring 773, and the degree of the break of the outer surfaces of the connection ring 773 and the locking ring 774 are not particularly limited in this embodiment, so as to satisfy the stability of the front end fixing ring 77.
The supporting angle α 1 formed by the supporting ring 772 and the connecting ring 773 is an obtuse angle and is used for supporting the front end structure of the main body of the virtual reality device, the locking angle β 1 formed by the connecting ring 773 and the locking ring 774 is also an obtuse angle and is used for locking when the front end fixing ring 77 is sleeved on the front end of the main body of the virtual reality device so as to prevent the front end of the main body of the virtual reality device from moving on the inner side of the front end fixing ring 77, and the degree of locking is increased by the mutual matching of the supporting angle α 1 and the locking angle β 1, so that the front end of the main body of the virtual reality device can be stably locked in the front end fixing ring 77 and the front end fixing ring 77 is prevented from easily falling off the virtual reality device.
In this embodiment, the angles of the support angle α and the locking angle β vary with the width of the outer surface 7733 of the connecting ring 773, that is, when the width of the outer surface 7733 of the connecting ring 773 increases, there are two cases, namely, when the inclination angle of the connecting ring 773 is constant, the connecting ring 773 moves in the direction of the virtual reality device, and the widths of the outer surfaces of the support ring 772 and the locking ring 774 are respectively varied, and when the angles of the support angle β and the locking angle β are constant, the inclination angle of the connecting ring 773 is varied, when the connection point between the support ring 772 and the connecting ring 773 is taken as a fixed point, the inclination angle of the connecting ring 773 is varied, so that the support angle α 1 is decreased and the locking angle β 1 is increased, when the connection point between the connecting ring 773 and the locking ring 774 is taken as a fixed point, the support angle α 1 is increased and the locking angle β 1 is decreased, when the width of the outer surface 7733 of the connecting ring 773 is decreased, there are also two cases, when the first case, the support angle 4835 and the locking angle β are not varied, and the second case of the second angle 586 is varied.
The angle ratio of the support angle α to the locking angle β is 0.8-1.25, in the present embodiment, the angle ranges of the support angle β and the locking angle β are both 120-150, and the angle ratio of the support angle β to the locking angle β varies with the width of the outer surface 7733 of the connecting ring 773. for example, when the angle ratio is 0.8, the support angle β is 120 °, the locking angle β is 150 °, when the angle ratio is 0.9, the support angle β is 130 °, the locking angle β is 145 °, or the support angle β is 135 °, the locking angle β is 150 °, etc. when the angle ratio is 1, the support angle α is 135 °, the locking angle 3611 is 135 °, or the support angle α is 140 °, the locking angle β is 140 °, etc. when the angle ratio is 1, the support angle α is 150 °, the locking angle 461 is 150 °, the optimum support angle 461, the support angle 461 is 120 °, the locking angle 7724 °, the optimum support angle is 7748 °, the optimum support angle 463, the locking angle 7724, the optimum locking angle is 7724, the optimum supporting angle is found when the angle is 1, the angle 7724, the optimum supporting angle is found.
Extension of the outer surface 7723 of the support ring 772 and extension of the outer surface 7743 of the lock ring 774 form a constraint angle, the magnitude of which is determined by the angular relationship of the support ring 772 and the lock ring 774.
In the present embodiment, the restriction angle satisfies the following relationships with the support angle α 1 and the lock angle β 1:
regulating angle (support angle α 1+ locking angle β 1) — 180 °, (1)
The restriction angle is used to define the degree to which the opening of the female leading end fixing ring 77 is expanded outward. The larger the angle of the restriction angle, the larger the opening degree of the front end fixing ring 77, that is, the shape gradually becomes one. And because the main body front end structure of the virtual reality device is matched with the inner side structure of the front end fixing ring 77, the outer edge of the main body front end of the virtual reality device also approaches a shape. When a user wears the virtual reality equipment with the shading component to experience a virtual environment, tensioning force towards the face direction of the user can be generated on the shading component, and the outer edges of the front end fixing ring 77 and the front end of the main body approach to a plane, so that the front end fixing ring 77 slides towards the tensioning force at the front end of the main body of the virtual reality equipment, the front end fixing ring 77 cannot be fixed at the front end of the main body of the virtual reality equipment for a long time, and the using effect of the virtual reality equipment is influenced.
The smaller the angle of the restriction angle, the smaller the opening degree of the front end fixing ring 77, that is, the V-shape is gradually formed. And because the main body front end structure of the virtual reality device is mutually matched with the inner side structure of the front end fixing ring 77, the outer edge shape of the main body front end of the virtual reality device gradually presents a V shape. Also when wearing, because a side 7741 of the lock ring 774 contacts with the front shell 1 of the virtual reality device, and the outer surface of the front shell 1 is flush with the front end face of the virtual reality device, and in order to make the front end of the body of the virtual reality device and the inner side of the front end fixing ring 77 inosculate and fix, the width of the lock ring 774 is reduced. The smaller the width of the locking ring 774 is, the locking function of the locking ring 774 cannot be fully exerted, so that when the virtual reality device is worn, the front end fixing ring 77 falls off from the front end of the virtual reality device due to the action of the tensioning force from the face direction of a user, namely, the shading assembly is easy to loosen from the front end of the virtual reality device in the use process, and the use effect of the virtual reality device cannot be influenced due to the fact that a closed space cannot be maintained for a long time.
Therefore, in order to stably fix the light blocking member to the front end of the body of the virtual reality device, it is necessary that the angle of the restriction angle is not excessively large or excessively small, and since the size of the restriction angle is related to the support angle α 1 and the lock angle β 1, and the support angle α 1 and the lock angle β 1 vary between 120 ° and 150 ° and satisfy a certain proportional relationship, in the present embodiment, the restriction angle is defined to vary between 80 ° and 110 ° according to the above-mentioned angles of the support angle α 1 and the lock angle β 1 and the formula (1). it is preferable that the support ring 772 and the lock ring 774 are perpendicular to each other when the restriction angle is 90 °, and in this state, the degree of outward expansion of the opening of the front end fixing ring 77 is optimal, so that the light blocking member can be stably fixed to the front end of the body of the virtual reality device.
As can be seen from fig. 28(a), the other side surface 7741 of the locking ring 774 is provided with an inclined ring 7740, and both sides of the inclined ring 7740 are respectively connected with the inner surface 7744 and the side surface 7741 of the locking ring 774. The tilt ring 7740 can reduce the weight of the entire component, and when the light-shielding assembly is in full contact with the virtual reality device, a transition at the contact position of the light-shielding assembly and the virtual reality device is not as abrupt, so that the light-shielding assembly can be more harmoniously viewed, and the aesthetic feeling of the light-shielding assembly is improved.
The inclined ring 7740 is used for forming a chamfer on the other side surface 7741 of the locking ring 774, that is, an extension line of the inclined ring 7740 and the inner surface 7744 forms a half chamfer γ; this half chamfer gamma is used for when the solid fixed ring 77 parcel of front end lives virtual reality equipment main part front end, can prevent that the internal surface 7744 of locked loop 774 from taking place to interfere with the preceding shell 1 of virtual reality equipment, influences the solid fixed ring 77's of front end stability, and then can avoid preceding shell 1 to the effort of locked loop 774 production, and make the solid fixed ring 77 of front end take place to loosen the phenomenon.
In order to form the half chamfer γ, the inclination angle of the inclined ring 7740 needs to be changed between 0 ° and 90 ° (excluding end point values); the optional angle range is 10 degrees to 80 degrees, the preferred angle range is 20 degrees to 70 degrees, the integral structure of the inclined ring 7740 is small, the thickness of the integral locking ring 774 is limited, and in order to make the whole design full of aesthetic feeling, the optimal angle range is 30 degrees to 60 degrees, particularly the angle within the range of 40 degrees to 50 degrees, specifically 45 degrees.
From another perspective, the width H1 of the inclined ring 7740 is 30% to 80% of the thickness δ 1 of the locking ring 774, and it can also be said that the half chamfer γ is an acute angle, that is, the width of the inner surface 7744 of the locking ring 774 is smaller than the width of the outer surface 7743, so as to prevent the inner surface 7744 of the locking ring 774 from interfering with the front shell 1 of the virtual reality device. The thickness δ 1 of the locking ring 774 is larger than the width of the inclined ring 7740, so that the inclined ring 7740 is not easy to damage while reducing the weight, because if the thickness is too thick, the weight of the inclined ring 7740 is increased, the weight of the whole shading assembly is increased, if the thickness is too thin, the inclined ring 7740 is easy to damage, and the multiple use of a user is not facilitated.
As can be seen from fig. 28(b), the support ring 772, the connection ring 773 and the locking ring 774 are connected in sequence, so that the cross-sectional shape of the front end fixing ring 77 takes on a concave shape with an outwardly expanding opening, so that the virtual reality device is smoothly mounted inside the front end fixing ring 77, and the front end fixing ring 77 is stably fixed at the front end of the body of the virtual reality device.
In order to reduce the stress on the user when wearing the virtual reality device and to prevent the user from being affected by the weight of the virtual reality device when wearing the virtual reality device for a long time, the weight of the entire light shield assembly needs to be reduced as much as possible. Then, the weight of the front end fixing ring 77 is reduced, and the weight of the entire shade assembly can be reduced to some extent. While reducing the overall weight of the shade 78, the strength of the support ring 772 of the front end fixing ring 77 should be ensured so that the user will not be easily damaged when using the shade 78. And to facilitate the attachment of the shade 78 to the inner surface 7724 of the support ring 772, a gap needs to be left on the inside of the support ring 772, the size of the gap being related to the thickness of the shade 78.
Thus, as shown in FIG. 29, one side 7721 of the inner surface 7724 of support ring 772 is provided with an edge ring 775 for abutting support ring 772; the protruding height of the edge ring 775 is the width of the reserved space. The other side 7722 of the inner surface 7724 of the support ring 772 is provided with a fastening area 776 for securing the shade 78; the edge ring 775 and the fastening regions 776, respectively, are continuously formed along the inner surface 7724 of the support ring 772, i.e., the inner surface of the support ring 772 is comprised of the edge ring 775 and the fastening regions 776.
Since the space formed by the edge ring 775 is the reserved space for installing the light shielding member 78, the width of the reserved space can be determined according to the thickness of the light shielding member 78 for the fixed installation of the light shielding member 78, i.e., the height of the protrusion of the edge ring 775 is determined according to the thickness of the light shielding member 78.
However, in order for support ring 772 to have sufficient stiffness to provide a reaction force against edge ring 775 to prevent support ring 772 from being damaged by failing to withstand the support force of edge ring 775, it is desirable that support ring 772 have a thickness δ 2 that is much greater than the protrusion height H2 of edge ring 775. In this embodiment, the optimum ratio of the protrusion height H2 of the edge ring 775 to the thickness δ 2 of the support ring 772 is: the protrusion height H2 of edge ring 775 is 25% to 30% of the thickness δ 2 of support ring 772.
For example, support ring 772 has a thickness δ 2 of 16mm, and when the thickness ratio is 25%, ridge ring 775 has a protrusion height H2 of 4 mm; when the thickness ratio is 30%, the protrusion height H2 of the edge ring 775 is 4.8 mm; when the thickness ratio is 28%, the protrusion height H2 of the edge ring 775 is 4.48 mm; preferably, when the thickness ratio is 27%, the projection height H2 of the edge ring 775 is 4.32 mm. The optimal thickness ratio allows the support ring 772 to have sufficient capacity to support the edge 775 ring while minimizing the weight of the shade assembly and preventing the support ring 772 from being too thick and heavy to increase the weight of the shade assembly. Too heavy a shade assembly can exert greater pressure on the user's face, affecting the user experience; and too heavy shading component can make virtual reality equipment produce the trend of gliding downwards, influences virtual reality equipment's result of use.
In order to ensure that the front end fixing ring 77 is matched with the front end structure of the main body of the virtual reality device, so that the light shielding assembly can be stably fixed at the front end of the main body of the virtual reality device, it is necessary that the shape of the front end fixing ring 77 is the same as the contour of the outer edge of the front end of the main body of the virtual reality device. That is, when the virtual reality device is VR glasses, the front end fixing ring 77 is also formed in a structure having a shape of glasses.
As shown in fig. 30, the front end fixing ring 77 is configured to have a front end fixing ring 77 structure viewed from the use of the user, that is, a front view of the front end fixing ring 77, and the front end fixing ring 77 further includes a brow connecting member 7701 having a circular arc shape, a nose connecting member 7704 having a circular arc shape, two bridge members 7702 having a circular arc shape, and two support members 7703 having a circular arc shape.
The brow portion connector 7701 functions as a base throughout the structure of the front end retainer ring 77, and corresponds to the brow portion, i.e., the forehead, of the user when in use. Therefore, the curvature of the eyebrow connecting member 7701 is also related to the two eyebrows of the user, i.e., the angle θ 1 between the tangents at the two end points of the eyebrow connecting member 7701 is related to the two eyebrows of the user.
The bridge 7702 plays a role of transition in the structure of the entire front end fixing ring 77, that is, both ends of the brow portion connecting member 7701 as a base are transitioned to the supporting member 7703, and the length of the brow portion connecting member 7701 is limited to maintain the front end fixing ring 77 in a stable structure. Therefore, the bridge 7702 is required to be bent more than necessary so that both ends of the brow connecting member 7701 can be smoothly rotated to perform its seating function. In use, bridge 7702 corresponds to a temple of a user.
In order to play a transitional role, one end of one of the bridges 7702 is connected with one end of the brow connecting member 7701, and one end of the other bridge 7702 is connected with the other end of the brow connecting member 7701; the two bridge pieces 7702 are symmetrically arranged along the center line 7705 of the eyebrow connecting piece 7701; the connection point of the brow connecting piece 7701 and the bridging piece 7702 is the outer tangent intersection point of the two corresponding arcs, which indicates that the bending direction of the arc where the brow connecting piece 7701 is located is opposite to the bending direction of the arc where the bridging piece 7702 is located; the centers of the two bridge members 7702 are respectively positioned in the fixed opening 771, the center of the brow connecting member 7701 is positioned outside the fixed opening 771, and the structure formed by the brow connecting member 7701 and the two bridge members 7702 is an inward convergent structure. Like this, not only can let the fixing of shading subassembly more fastening on virtual reality equipment, after using a period, can also prevent that front end fixed ring 77 from warping and upwarping, influencing the solid fixed ring 77's of front end stability. Furthermore, the shading component can be combined with the virtual reality equipment to be lighter and thinner in appearance.
Since the two bridges 7702 are located near the temples of the user, respectively, it is illustrated that the distance between the two bridges 7702 is similar to the width of the face of the user. Therefore, the distance between the center points C of the two bridges 7702 is taken as a criterion for defining the length of the other components.
The distance between the center points C of the two bridges 7702 also varies due to the difference in the head shape of each user or the difference in the age of the user, so that the width of the face of each user is different. Typically, adult faces are between about 13cm and 20cm wide, while minor faces are between about 10cm and 15cm wide, and as can be seen, the most common face widths are between 13cm and 15 cm. I.e., the distance L2 between the center points C of the two bridges 7702 varies between 10cm and 20cm, preferably the distance L2 is between 13cm and 15cm for optimum size.
In order to achieve the transition effect, the bridge 7702 needs to exhibit a large-angle curvature, and an angle θ 2 between tangents at both end points of the bridge 7702 is required to vary between 60 ° and 80 ° due to the limitation of the face width.
To exhibit the transition, the radius of curvature of the bridge 7702 gradually decreases from one end to the center point C and gradually increases from the center point C to the other end. The radius of curvature of the bridges 7702 varies between one sixth and one quarter of the distance L2 between the center points C of the two bridges 7702; the distance L3 between the two end points of the bridge 7702 accounts for 15% -30% of the distance L2 between the center points C of the two bridges 7702.
For example, the distance L2 varies between 10cm and 20cm, and when the radius of curvature of the bridge 7702 is one sixth of the distance L2, the radius of curvature of the bridge 7702 varies between 1.67cm and 3.33cm, i.e., the radius of curvature at the end point is 3.33cm and the radius of curvature at the center point C is 1.67 cm; when the radius of curvature of the bridge 7702 is one-quarter of the distance L2, the radius of curvature of the bridge 7702 varies between 2.5cm and 5cm, i.e., the radius of curvature at the end point is 5cm and the radius of curvature at the center point C is 2.5 cm; when the radius of curvature of the bridge 7702 is one-fifth of the distance L2, the radius of curvature of the bridge 7702 varies between 2cm and 4cm, i.e., the radius of curvature at the end point is 4cm and the radius of curvature at the center point C is 2 cm. It can be seen that the radius of curvature of the bridge 7702 varies between 3.33cm and 5cm at the end points and between 1.67cm and 2.5cm at the center point.
The distance L3 between both end points of the bridge 7702 occupies 15% to 30% of the distance L2, and the size and the degree of bending of the bridge 7702 can be defined according to the radius of curvature of the bridge 7702, thereby achieving the transition effect of the bridge 7702. For example, when distance L3 represents 15% of distance L2, distance L3 may take any value between 1.5cm and 3 cm; when the distance L3 occupies 30% of the distance L2, the distance L3 may take any value between 3cm and 6 cm; when the distance L3 occupies 20% of the distance L2, the distance L3 may take any value between 2cm and 4 cm; when the distance L3 occupies 25% of the distance L2, the distance L3 may take any value between 2.5cm and 5 cm. Preferably, for the optimal distance ratio when the distance L3 occupies 23.35% of the distance L2, the distance L3 may take any value between 2.335cm and 4.67 cm. The width of the face of the human body is between 13cm and 15cm, so that the distance L3 is the most suitable size selected from 3.0355cm to 3.5025 cm; in particular, the most common width is when the width of the human face is 14cm, in which case the distance L4 is 3.269 cm.
Since the curvature of the eyebrow links 7701 is related to the two eyebrows of the user, and the eyebrow links 7701 can perform a high-level base function, the curvature of the eyebrow links 7701 does not need to be excessively large. The curvature of the brow portion link 7701 is represented by an angle θ 1 between tangents at both end points of the brow portion link 7701. In this embodiment, the included angle θ 1 is 2 to 2.9 times the included angle θ 2 between the tangents at the two end points of the bridge 7702. Since the included angle θ 2 varies from 60 ° to 80 °, the included angle θ 1 varies from 140 ° to 174 °. For example, when the included angle θ 2 is 75 °, and the included angle θ 1 is 2.28 times of the included angle θ 2, the included angle θ 1 is 171 °; when the included angle theta 2 is 60 degrees and the included angle theta 1 is 2.9 times of the included angle theta 2, the included angle theta 1 is 174 degrees; when the included angle theta 2 is 70 degrees, and the included angle theta 1 is 2 times of the included angle theta 2, the included angle theta 1 is 140 degrees.
The length of the brow portion connecting member 7701 is the distance L1 between its two end points. In order to provide the eyebrow connecting member 7701 with optimal stability and function as a base, the length of the eyebrow connecting member 7701 should not be too short to bear the weight of other parts, and the eyebrow connecting member 7701 should not be too long to cause unnecessary waste. In this embodiment, the distance L1 is 50% to 75% of the distance L2 between the center points C of the two bridges 7702.
For example, when the distance L1 occupies 50% of the distance L2, the distance L1 may take any value between 5cm and 10 cm; when the distance L1 occupies 75% of the distance L2, the distance L1 may take any value between 7.5cm and 15 cm; when the distance L1 occupies 55% of the distance L2, the distance L1 may take any value between 5.5cm and 11 cm; when the distance L1 occupies 60% of the distance L2, the distance L1 may take any value between 6cm and 12 cm; when the distance L1 occupies 65% of the distance L2, the distance L1 may take any value between 6.5cm and 13 cm; when the distance L1 occupies 70% of the distance L2, the distance L1 may take any value between 7cm and 14 cm. Preferably, the optimal distance ratio is when the distance L1 accounts for 68.57% of the distance L2, and in this case, the distance L1 may take any value between 6.857cm and 13.714 cm. The width of the face of the human body is between 13cm and 15cm and is the most suitable size, so that the distance L1 is the most suitable size which is the size between 8.9141cm and 10.2855cm, namely 8.9141cm is adopted as the distance L1 when the distance L2 is 13cm, and 10.2855cm is adopted as the distance L1 when the distance L2 is 14 cm; in particular, the most common width is when the width of the human face is 14cm, in which case the distance L1 is 9.5998 cm.
The supporting member 7703 serves as a supporting base in the structure of the entire front end fixing ring 77 through a transition section, that is, the brow connecting member 7701 is supported by the bridge 7702, so that the entire front end fixing ring 77 has good stability. In use, the support members 7703 correspond to the face of the user, and the support members 7703 are bent to a greater degree than the bridges 7702 in order to conform to the curvature of the face of the user.
One end of each supporting element 7703 is connected to the other end of one bridging element 7702, and the connection point between the bridging element 7702 and the supporting element 7703 is an inscribed intersection point of two arcs, which indicates that the bending direction of the arc where the supporting element 7703 is located is the same as the bending direction of the arc where the bridging element 7702 is located; the centers of the two supporting pieces 7703 are positioned in the fixed opening 771; the other end of each support member 7703 is commonly connected to both ends of a nose link 7704, the arch apex of the nose link 7704 being adjacent to the brow link 7701.
The radius of curvature of the support members 7703 varies between one quarter and one third of the distance L2 between the center points C of the two bridge members 7702; the distance L4 between the two end points of the supporting member 7703 accounts for 25% -40% of the distance L2 between the center points C of the two bridging members 7702.
The radius of curvature of the supporting member 7703 is larger than that of the bridging member 7702, so that the supporting member 7703 has a better supporting force to support the brow portion connecting member 7701. Therefore, the distance L4 between the two end points of the supporting member 7703 occupies 25% to 40% of the distance L2, and the curvature radius of the supporting member 7703 can define the size and the bending degree of the supporting member 7703, thereby achieving the supporting effect of the supporting member 7703.
With respect to the size of the radius of curvature of the supporting member 7703, for example, since the distance L2 varies between 10cm and 20cm, when the radius of curvature of the supporting member 7703 is one-quarter of the distance L2, the radius of curvature of the supporting member 7703 varies between 2.5cm and 5cm, that is, the radius of curvature at the end point is 5cm and the radius of curvature at the center point is 2.5 cm; when the radius of curvature of the support 7703 is one-third of the distance L2, the radius of curvature of the support 7703 varies between 3.33cm and 6.67cm, i.e., the radius of curvature at the end points is 6.67cm and the radius of curvature at the center point is 3.33 cm; and because the width of the human face is between 13cm and 15cm, the most suitable size, at this moment, the radius of curvature of the supporting piece 7703 is changed between 4.33cm and 5 cm; in particular, when the width of the human face is 14cm, which is the most common width, the radius of curvature of the supporting member 7703 is 4.67 cm.
Regarding the dimension of the distance L4 between the two end points of the supporting member 7703, for example, when the distance L4 occupies 25% of the distance L2, the distance L4 may take any value between 2.5cm and 5 cm; when the distance L4 occupies 30% of the distance L2, the distance L4 may take any value between 3cm and 6 cm; when the distance L4 occupies 35% of the distance L2, the distance L4 may take any value between 3.5cm and 7 cm; when the distance L4 occupies 40% of the distance L2, the distance L4 may take any value between 4cm and 8 cm. Preferably, for the optimal distance ratio when the distance L4 accounts for 33.64% of the distance L2, the distance L4 may take any value between 3.364cm and 6.728 cm. The width of the face of the human body is between 13cm and 15cm, so that the distance L4 is the most suitable size selected from 4.3732cm to 5.046 cm; in particular, the most common width is when the width of the human face is 14cm, in which case the distance L4 is 4.7096 cm.
The nose attachment 7704 serves as another transition segment throughout the construction of the forward end retainer ring 77, corresponding to the user's nose, and is secured thereto by an arch. The two ends of the nose connecting piece 7704 are respectively connected with a supporting piece 7703, which can support the supporting piece 7703 to make the supporting piece 7703 exert a good supporting force.
The brow connecting member 7701, nose connecting member 7704, bridge 7702 and support member 7703 are connected in sequence in accordance with the above principles to form a closed loop configuration, i.e., a front end retainer ring 77. In the use, each part plays the function of self to and the mutual cooperation of function between two adjacent parts, can make front end fixed ring 77 have good stability, prevent that front end fixed ring 77 from in the use, warp because of the influence of external effort, leading to the enclosure space to be destroyed, make the shading subassembly lose the effect of shading, influence virtual reality equipment's result of use.
The brow connecting member 7701, the nose connecting member 7704, the bridge 7702 and the supporting member 7703 divide the supporting ring 772, the connecting ring 773 and the locking ring 774 into six parts, respectively, that is, each part includes a partial structure of the supporting ring 772, the connecting ring 773 and the locking ring 774 connected in sequence, so that the cross-sectional shapes of the brow connecting member 7701, the nose connecting member 7704, the bridge 7702 and the supporting member 7703 are concave, respectively.

The first connecting portion 77041 and the second connecting portion 77044 are respectively used for connecting the supporting member 7703, and since the supporting member 7703 is used for supporting the brow portion connecting member 7701 via the bridge 7702, the first connecting portion 77041 and the second connecting portion 77044 respectively provide a supporting force for the supporting member 7703 connected thereto, so that the supporting force of the supporting member 7703 is more stable. The connection point of the first connection portion 77041 and the supporting member 7703 is an inscribed intersection point of two arcs, which indicates that the bending direction of the arc where the first connection portion 77041 is located is the same as the bending direction of the arc where the supporting member 7703 is located.
The other end of the first connecting portion 77041 is connected to one end of the first curved portion 77042, and the connection point of the first connecting portion 77041 and the first curved portion 77042 is an external tangent intersection point of two arcs, which indicates that the bending direction of the arc where the first connecting portion 77041 is located is opposite to the bending direction of the arc where the first curved portion 77042 is located; the other end of the second connecting portion 77044 is connected to one end of the second curved portion 77043, and the connection point of the second connecting portion 77044 and the second curved portion 77043 is the circumscribed intersection point of two arcs, which indicates that the bending direction of the arc in which the second connecting portion 77044 is located is opposite to the bending direction of the arc in which the second curved portion 77043 is located.
The circle center of the first connecting portion 77041 and the circle center of the second connecting portion 77044 are respectively located in the fixing opening 771, so that the first connecting portion 77041 and one of the supporting members 7703, and the second connecting portion 77044 and the other supporting member 7703 can be smoothly connected, and further, the supporting force of the first connecting portion 77041 and the supporting force of the second connecting portion 77044 are all applied to the corresponding supporting members 7703, so that the waste of the supporting force is avoided, and the weakening of the supporting force of the supporting members 7703 is influenced.
The other end of the first curved portion 77042 is connected to one end of the second curved portion 77043, and the connection point of the first curved portion 77042 and the second curved portion 77043 is an inscribed intersection point of two arcs, which indicates that the bending direction of the arc where the first curved portion 77042 is located is the same as the bending direction of the arc where the second curved portion 77043 is located; the center of the first bend 77042 and the center of the second bend 77043 are located outside of the fixed opening 771, respectively, so that the nasal connector 7704 assumes an arch shape.
In order to facilitate the adaptation of the nose connector 7704 to the nose of the user and the stability of the front end fixing ring 77, a distance L5 between the intersection point D of the first curved portion 77042 and the second curved portion 77043 and the brow connector 7701 is required to be 45% to 60% of the vertical height H3 from the end point of the brow connector 7701 to the end point of the support 7703 where the nose connector 7704 is connected. And the distance L6 between the two end points of the first connecting part 77041 and the second connecting part 77044 connecting the supporting part 7703 occupies 45% -55% of the distance L2 between the central points C of the two bridge parts 7702;

One end of the front end fixing ring 77 in the shading assembly is in contact with the outer edge of the front shell 1, namely, one side of the locking ring 774 provided with the inclined ring 7740 is in contact with the outer edge of the front shell 1, and because the inclined ring 7740 and the inner surface 7744 form a half chamfer angle gamma, the inner surface 7744 of the locking ring 774 cannot interfere with the surface of the front shell 1. Therefore, avoid when wearing the virtual reality equipment that is equipped with shading components, because of the solid fixed ring 77 of front end takes place to interfere with preceding shell 1, and make preceding shell 1 produce outside effort to front end fixed ring 77, lead to front end fixed ring 77 to loosen from virtual reality equipment's picture frame 301 and take off, destroy the enclosure space, external light can consequently get into, influence user's visual effect.
In order to connect the front case 1 and the front end fixing ring 77 seamlessly, the outer edge shape of the front case 1 is the same as the shape of the locking ring 774 in the front end fixing ring 77.
The back shell 3 is a back plate of the virtual reality device and is arranged on one side of the mirror frame 301 close to the face of the user, so that the back shell 3, the face of the user and the shading assembly form a closed space.
The left temple 5 and the right temple 4 are collectively referred to as temples, and the structures of the temples are not substantially different. The front end of each glasses leg is provided with a bulge which is used for being embedded into a groove on the glasses leg connecting part on the rear shell 3. In the unfolded state, the left leg 5 and the right leg 4 are respectively in the shape of an inward-bent arc, so that the head of a user can be clamped conveniently.
And through holes are respectively formed in the left leg 5 and the right leg 4 and are used for fixedly connecting the locking hole 755 in the shading assembly with the through holes through a connecting piece, so that the shading assembly and the virtual reality equipment are fixed. That is, the right temple 4 is coupled to the first curved surface 75 through the coupling member and the locking hole 755; the left temple 5 is coupled to the second curved surface 76 by a coupling member and a locking hole 755.
Specifically, as shown in fig. 35, the rear case 3 and the mirror frame 301 form a receiving cavity 46, and the receiving cavity 46 is used for accommodating the optical system, the PCBA board and the optical sensing component;
the frame 301 in this embodiment is a main body provided in the first aspect, that is, the frame 301 of the virtual reality device is a main body of the aforementioned virtual reality device. The shading component is connected with the virtual reality device by utilizing the structural matching of the front end fixing ring 77 and the mirror frame 301 to realize the fixation.
As shown in fig. 36, the frame 301 has a symmetrical structure along the longitudinal centerline 3010; and in order that the front end fixing ring 77 can be fixed at the front end of the mirror frame 301, the appearance of a gap is avoided, so that external light enters a closed space to influence the visual effect of a user, and the shape of the outer edge of the mirror frame 301 is required to be the same as that of the inner edge of the front end fixing ring 77, so that the two can realize structural matching.
As shown in fig. 37, the frame 301 includes a support frame 3011 and a guide frame 3012 having a shape similar to the front end fixing ring 77; the support frame 3011 serves as a bridge support between the front case 1 and the rear case 3, and is used to support the support ring 772 portion of the front end fixing ring 77; the guide frame 3012 can implement transition connection between the support frame 3011 and the front shell 1, and is used to support the connection ring 773 and the locking ring 774 in the front end fixing ring 77; the inner surface of the guide frame 3012 is used to connect with the front case 1 by a snap. The structure formed by the supporting frame 3011 and the guiding frame 3012 can match with the inner structure of the front end fixing ring 77, so that the front end fixing ring 77 can be fixed on the outer surface of the mirror frame 301, and the using effect of the virtual reality device with the shading assembly is better.
The support frame 3011 and the guide frame 3012 have similar shapes, differing only in that the dimensions of the two are slightly different. In order to stably fix the light blocking unit to the virtual reality device, the inner side of the light blocking unit and the outer side of the frame 301 of the virtual reality device need to have the same structure and shape, and for example, if the shape of the front end fixing ring 77 is rectangular, square, or other different regular shapes, the shape of the frame 301, that is, the shapes of the support frame 3011 and the guide frame 3012 need to be changed accordingly. For example, when the front end fixing ring 77 is selected to have a shape corresponding to a spectacle shape with a constant curvature, the shape of the frame 301 is also preferably a spectacle shape, that is, the shape of the frame 301 is determined by the shape of the inner edge of the front end fixing ring 77.
Specifically, the cross-sectional shape of the support frame 3011 is V-shaped, and the degree of outward expansion of the opening is close to a plane, so that the mirror frame 301 side of the virtual reality device can be conveniently installed with the shading component, one side of the support frame 3011 is connected with one side of the guide frame 3012, so that the outer surface 30111 of the support frame 3011 and the outer surface 30121 of the guide frame 3012 form a support vertex angle α 2.
The supporting vertex angle α 2 is an obtuse angle, and is used to cooperate with the supporting vertex α 1 of the front end fixing ring 77, so that the front end of the frame 301, i.e. the joint between the supporting frame 3011 and the guiding frame 3012, is abutted against the joint between the supporting ring 772 and the connecting ring 773, and the supporting frame 3011 can be fixed inside the front end fixing ring 77.
As shown in fig. 38 and fig. 39(a) (b), the outer surface 30111 of the support frame 3011 is opposite to the inner surface 7724 of the support ring 772 so that the support frame 3011 abuts against the inner surface of the support ring 772 to achieve structural fit, and since the inner surface of the support ring 772 is provided with the edge ring 775, the vertex of the edge ring 775 abuts against the outer surface 30111 of the support frame 3011 to form a gap between the support frame 3011 and the support ring 772, so that the angle of the support vertex angle α 2 is smaller than the angle of the support angle α 1 to form a clearance angle δ, and so that the support vertex angle α 2 and the angle of the clearance angle δ are equal to the support angle α 1.
The gap is formed for fixedly mounting the shade 78 such that the shade 78 is secured along the gap within the fastening area 776 of the support ring 772; the angle of the clearance angle δ depends on the thickness of the shade 78, i.e., the thicker the shade 78, the greater the angle of the clearance angle δ, and thus the greater the protrusion height H3 of the edge ring 775; the thinner the shade 78, the smaller the angle of the clearance angle δ, and thus the lower the protrusion height H3 of the rim 775.
In this embodiment, the angle of the supporting vertex angle α 2 is 97% -99% of the angle of the supporting angle α 1.
For example, it is known from support angle α 1 provided in the first aspect that optimum support angle α 1 is 133 °, and therefore, support apex angle α 22 is 129 ° and clearance angle δ is 4 ° when angle of support apex angle α 02 is 97% of angle of support angle α 11, support apex angle α 2 is 132 ° and clearance angle δ is 1 ° when angle of support apex angle α 32 is 99% of angle of support angle α 1, support apex angle α 2 is 130 ° and clearance angle δ is 3 ° when angle of support apex angle α 2 is 98% of angle of support angle α 1, and it is preferable that optimum angle ratio when angle of support apex angle α 2 is 98.5% of angle of support angle α 1, support apex angle α 2 is 131 ° and clearance angle δ is 2 °.
The outer surface 30121 of the guide frame 3012 is attached to the inner surface 7734 of the connecting ring 773, and the end surface 30122 of the guide frame 3012 is attached to the inner surface 7744 of the locking ring 774, so that the guide frame 3012 abuts against the inner surfaces of the connecting ring 773 and the locking ring 774 to achieve structural cooperation, and a locking vertex angle β 2 is formed between the outer surface 30121 of the guide frame 3012 and the end surface 30122 due to the transition effect of the guide frame 3012.
Because the outer surface 30121 and the end surface 30122 of the guide frame 3012 are attached to the inner surface 7734 of the connecting ring 773 and the inner surface 7744 of the locking ring 774, the angle of the formed locking vertex angle β 2 is the same as the angle of the formed locking vertex angle β 1, the locking vertex angle β 2 and the locking corner β 1 are matched with each other to play a role in locking, so that the front end fixing ring 77 is prevented from moving on the outer edge of the frame 301, the locking degree of the front end fixing ring 77 fixed on the frame 301 is increased, and the shading assembly is prevented from being loosened from the frame 301 of the virtual reality device, a closed space is prevented from being damaged, and the visual effect of a user is influenced.
It should be noted that the front end of the main body of the virtual reality device mentioned in the first aspect is the front end of the frame 301 provided in this embodiment, and the front end portion specifically refers to the guide frame 3012 and a portion of the support frame 3011 that connects one end of the guide frame 3012, and the front end of the frame 301 is made to be convex by the structure of the support frame 3011 and the guide frame 3012. The convex structure of the frame 301 is matched with the concave structure of the front end fixing ring 77, so that when the frame 301 is installed along the direction from the light-shielding member 78 to the front end fixing ring 77, the frame 301 is fixed on the inner side of the front end fixing ring 77.
The schematic diagram when the shading assembly is installed on the outer side of the virtual reality device is as shown in fig. 40, the frame 301 of the virtual reality device is surrounded by the closed hollow region of the shading assembly, so that the front end fixing ring 77 of the shading assembly wraps the front end of the frame 301 of the virtual reality device, and the fixed relation between the shading assembly and the virtual reality device is realized by utilizing the mutual matching of the inner side structure of the front end fixing ring 77 and the outer side structure of the frame 301, namely, the matching of the supporting vertex angle α 2 and the supporting angle α 1 and the matching of the locking vertex angle β 2 and the locking angle β 1.
In order to realize seamless fixed connection between the light shielding assembly and the virtual reality device, in the matching structure of the front end fixing ring 77 and the frame 301, the width of the outer surface 30121 of the guide frame 3012 is required to be equal to the width of the inner surface 7734 of the connecting ring 773, and the width of the end surface 30122 of the guide frame 3012 is required to be equal to the width of the inner surface 7744 of the locking ring 774, so that stable connection between the light shielding assembly and the virtual reality device is realized, and the light shielding assembly is prevented from being loosened from the frame 301 of the virtual reality device due to acting force in the wearing process.
In order to ensure stable fixation of the light shield assembly to the virtual reality device as a whole, it is necessary that the outer edge profile of the frame 301 is the same as the shape of the front end fixing ring 77.
