In the present embodiment, strut angle α 1 and lock angle β 1 angle occur with the width of outer surface 7733 of connection ring 773 Change, i.e., when the 7733 width increase of outer surface of connection ring 773, now including two kinds of situations：A kind of is inclining for connection ring 773 Rake angle is constant, and connection ring 773 moves along the direction of virtual reality device, while makes the outer of support ring 772 and locking ring 774 Face width changes respectively, and now strut angle α 1 and lock angle β 1 angle are constant.It is for second the inclination of connection ring 773 Angle changes, and now, when using the junction of support ring 772 and connection ring 773 as fixed point, changes inclining for connection ring 773 Rake angle so that strut angle α 1 diminishes, and lock angle β 1 increases；When using the junction of connection ring 773 and locking ring 774 as fixed point When, now strut angle α 1 becomes big, and lock angle β 1 diminishes.When the width of the outer surface 7733 of connection ring 773 reduces, equally include Two kinds of situations, during the first situation, strut angle α 1 and lock angle β 1 angle are constant；During second of situation, strut angle α 1 and lock The angle change rule of angle beta 1 is determined with second above-mentioned of situation on the contrary, here is omitted.

Strut angle α 1 and lock angle β 1 angle ratio is 0.8~1.25.In the present embodiment, strut angle α 1 and lock angle β 1 Angular range between 120 °~150 °, and the change of the width of outer surface 7733 with connection ring 773, strut angle α 1 And lock angle β 1 angle ratio changes between 0.8~1.25.For example, when angle ratio is 0.8, strut angle α 1 is 120 °, lock angle β 1 be 150 °.When angle ratio is 0.9, strut angle α 1 is 130 °, lock angle β 1 is 145 °；Or support Angle α 1 is 135 °, lock angle β 1 is 150 °, etc..When angle ratio is 1, strut angle α 1 is 135 °, lock angle β 1 is 135 °；Or Person, strut angle α 1 is 140 °, lock angle β 1 is 140 °, etc..When angle ratio is 1.25, strut angle α 1 is 150 °, lock angle β 1 is 120 °.Preferably, be optimal angle ratio when angle ratio is 0.97, now strut angle α 1 be 133 °, lock angle β 1 be 137°.When strut angle α 1 and lock angle β 1 is using optimal angle, support ring 772, connection ring 773 and locking ring 774 can be made The structure of formation is more stable.

The extended line of outer surface 7723 of support ring 772 and the extended line of outer surface 7743 of locking ring 774, which are formed, restricts angle, system The size at about angle is decided by support ring 772 and the angular relationship of locking ring 774.

In the present embodiment, restrict angle and meet such as following formula relation with strut angle α 1 and lock angle β 1：

Restrict angle=- 180 ° of (strut angle α 1+ lock angles β 1)； (1)

Angle is restricted to be used to limit the degree that the outward opening of concave forward end retainer ring 77 extends.If the angle for restricting angle is got over Greatly, illustrate that the extent of opening of front end retainer ring 77 is bigger, i.e., a shape is gradually presented.And due to the body front end of virtual reality device The inside structure of structure and front end retainer ring 77 cooperates so that the outer rim of the body front end of virtual reality device also convergence one Shape.When user wears the virtual reality device experiencing virtual environment with light shield device, light shield device can be produced to user The tightening force in facial direction, and due to the outer rim of front end retainer ring 77 and body front end all convergence planes so that front end retainer ring 77 slide in the body front end of virtual reality device to the direction of tightening force, and then cause front end retainer ring 77 not consolidate for a long time The body front end of virtual reality device is scheduled on, influences the using effect of virtual reality device.

If the angle for restricting angle is smaller, illustrate that the extent of opening of front end retainer ring 77 is smaller, i.e., V-arrangement is gradually presented.And Because the body front end structure of virtual reality device and the inside structure of front end retainer ring 77 cooperate so that virtual reality is set V-arrangement is also gradually presented in the outer rim shape of standby body front end.Equally wear when, due to locking ring 774 one side 7741 with The fore shell 1 of virtual reality device contacts, and the outer surface of fore shell 1 is concordant with the front end surface of virtual reality device, and in order that The interior side-to-side anastomosis of the body front end of virtual reality device and front end retainer ring 77 is fixed so that the width of locking ring 774 reduces.And The width of locking ring 774 is smaller, then can not give full play to the function of its locking, causes when wearing, because coming from user's face side To tightening force effect so that front end retainer ring 77 comes off from the front end of virtual reality device, i.e., easily makes light shield device Released during from the front end of virtual reality device, and then closing space can not be maintained for a long time, influence virtual reality device Using effect.

Therefore, in order that light shield device can be firmly secured at the body front end of virtual reality device, it is necessary to limit system About the angle at angle can not be excessive, can not be too small.Again because the size for restricting angle is relevant with strut angle α 1 and lock angle β 1, and prop up Support angle α 1 and lock angle β 1 changes between 120 °~150 °, and meets certain proportionate relationship.Therefore, in the present embodiment, root According to above-mentioned strut angle α 1 and lock angle β 1 angle, and formula (1), limit restriction angle and change between 80 °~110 °.It is preferred that , when it is 90 ° to restrict angle, i.e., support ring 772 and locking ring 774 are in state is mutually perpendicular to, and under such a state, front end is fixed The degree of the outward opening extension of ring 77 is optimal, before light shield device being enable to be firmly secured at the main body of virtual reality device End.

It can be seen that from Figure 28 (a), the another side 7741 of locking ring 774 is provided with inclined ring 7740, inclined ring 7740 Both sides are connected with the inner surface 7744 of locking ring 774 and side 7741 respectively.The setting of inclined ring 7740 can not only be with inciting somebody to action entirety Part make entity compared to mitigate weight, moreover it is possible to when light shield device fully contacts with virtual reality device, allow light shield device and The contact position of virtual reality device is unlikely to seem loftier in the presence of a transition, allows its outward appearance to seem more to coordinate, increase The aesthetic feeling of light shield device.

Inclined ring 7740 is used to make to form chamfering at the another side 7741 of locking ring 774, i.e. inclined ring 7740 and interior table The extended line in face 7744 forms half chamfering γ；Half chamfering γ is used for when front end retainer ring 77 wraps virtual reality device main body During front end, it can prevent the inner surface 7744 of locking ring 774 from being interfered with the fore shell 1 of virtual reality device, influence front end and fix The stability of ring 77, and then fore shell 1 can be avoided to active force caused by locking ring 774, and get loose front end retainer ring 77 Phenomenon.

In order to form half chamfering γ, it is necessary to which the angle of inclination of inclined ring 7740 changes (not including end points between 0 °~90 ° Value)；Optional angular range is 10 °~80 °, and preferably angular range is 20 °~70 °, due to the entirety knot of inclined ring 7740 Structure is smaller, and occupies the finite thickness of integral locking ring 774, in order to allow whole design to be full of aesthetic feeling, optimal angle model Enclose for 30 °~60 °, particularly the angle in the range of 40 °~50 °, it is specific such as 45 °.

In terms of another angle, the width H1 of inclined ring 7740 is the 30%~80% of the thickness δ 1 of locking ring 774, also may be used It is acute angle to illustrate half chamfering γ, i.e., the width of inner surface 7744 of locking ring 774 is less than the width of outer surface 7743, can just prevent from locking The fore shell 1 of the inner surface 7744 and virtual reality device of determining ring 774 interferes.The thickness δ 1 of locking ring 774 is more than inclined ring 7740 width, it is ensured that inclined ring 7740 is hardly damaged while weight is reduced, because if blocked up, may cause to tilt The increase of the weight of ring 7740, and then increase the weight of overall light shield device, if excessively thin, inclined ring 7740 can be caused to be easily damaged, User is not easy to be used for multiple times.

It can be seen that from Figure 28 (b), support ring 772, connection ring 773 and locking ring 774 are sequentially connected, and make front end retainer ring The spill of outward opening extension is presented in 77 shape of cross section, in order to which virtual reality device is successfully arranged on front end retainer ring 77 inner side, and front end retainer ring 77 is firmly secured at the body front end of virtual reality device.

Pressure is born when user wears virtual reality device in order to reduce, user is not showed virtually in extended wear The influence of real weight of equipment, it is necessary to reduce the overall weight of light shield device as far as possible.So, the weight of front end retainer ring 77 is reduced Amount, the weight of overall light shield device can be reduced to a certain degree.While 78 overall weight of shading piece is reduced, before also needing guarantee The intensity of support ring 772 of retainer ring 77 is held, in order to which user will not be damaged easily when using shading piece 78.And in order to It is easy to the inner surface 7724 of support ring 772 to fix shading piece 78, it is necessary to a fixed gap is left in the inner side of support ring 772, space Size is relevant with the thickness of shading piece 78.

Therefore, as shown in figure 29, the side 7721 of the inner surface 7724 of support ring 772, which is provided with, is used to withstand support ring 772 Rib ring 775；The width that the rising height of rib ring 775 as interspaces in advance.The opposite side 7722 of the inner surface 7724 of support ring 772 is set There is the fastening zone 776 for fixing shading piece 78；Rib ring 775 and fastening zone 776 connect along the inner surface 7724 of support ring 772 respectively Continuous to be formed, i.e., the inner surface of support ring 772 is made up of rib ring 775 and fastening zone 776.

By the space that rib ring 775 is formed is to install the pre- of shading piece 78 to interspace, therefore, for shading piece 78 It is fixedly mounted, the width to interspace in advance can be depending on the thickness of shading piece 78, i.e., the rising height of rib ring 775 is according to shading piece Depending on 78 thickness.

But in order to which support ring 772 has enough hardness to be supplied to the reaction force of rib ring 775, prevent support ring 772 because can not Bear the support force of rib ring 775 and breakage occur, therefore, it is necessary to the thickness δ 2 of support ring 772 is high much larger than the projection of rib ring 775 Spend H2.In the present embodiment, the rising height H2 and the thickness δ 2 of support ring 772 of rib ring 775 optimal proportion relation are：Rib ring 775 Rising height H2 be the thickness δ 2 of support ring 772 25%~30%.

For example, the thickness δ 2 of support ring 772 is 16mm, when thickness ratio is 25%, the rising height H2 of rib ring 775 is 4mm；When thickness ratio is 30%, the rising height H2 of rib ring 775 is 4.8mm；When thickness ratio is 28%, rib ring 775 is dashed forward It is 4.48mm to play height H2；Preferably, it is the rising height of optimal thickness ratio, now rib ring 775 when thickness ratio is 27% H2 is 4.32mm.Optimal thickness ratio can make support ring 772 have enough endurance, to bear rib ring 775 to caused by it While support force, the weight of light shield device is reduced as far as possible, prevents that the thickness of support ring 772 is excessively thick and heavy and increases light shield device Weight.Overweight light shield device can apply larger pressure to the face of user, influence Consumer's Experience；And overweight shading Component can make virtual reality device produce the trend to downslide, influence the using effect of virtual reality device.

In order to ensure that front end retainer ring 77 and the body front end structure of virtual reality device cooperate, so that light shield device The body front end of virtual reality device, therefore, it is necessary to the shape and virtual reality of front end retainer ring 77 can be firmly secured at The body front end outer margin contour of equipment is identical.I.e. when virtual reality device is VR glasses, front end retainer ring 77 will also use eye The structure of mirror shape.

The structure of front end retainer ring 77 from angle, the i.e. front view of front end retainer ring 77 such as Figure 30 institutes are used from user Show, front end retainer ring 77 also including being in supercilium connector 7701, the nose connector 7704, two of domed shape of arc-shaped The bridgeware 7702 of arc-shaped and two support members 7703 in arc-shaped.

Supercilium connector 7701 plays a part of pedestal in the structure of whole front end retainer ring 77, when in use, with The supercilium at family, i.e., it is corresponding at forehead.Therefore, the radian of supercilium connector 7701 is also relevant with two superciliums of user, i.e. eyebrow Angle theta 1 is related to two superciliums of user between tangent line at two end points of portion's connector 7701.

Bridgeware 7702 plays a part of transition in the structure of whole front end retainer ring 77, will be as the supercilium of pedestal The both ends of connector 7701 are transitioned on support member 7703, and limit the length of supercilium connector 7701, so that front end retainer ring 77 keep stable structure.Therefore, it is necessary to which the degree of crook of bridgeware 7702 is more larger, so that the both ends of supercilium connector 7701 Can successfully it turn round, to play the effect of its pedestal.When in use, bridgeware 7702 is corresponding with the temple of user.

In order to play transitional function, one end of one of bridgeware 7702 is connected with one end of supercilium connector 7701, One end of another bridgeware 7702 is connected with the other end of supercilium connector 7701；And two bridgewares 7702 connect along supercilium The center line 7705 of part 7701 is symmetrical arranged；Supercilium connector 7701 is corresponding two circular arcs with the tie point of bridgeware 7702 Circumscribed intersection point, illustrate the bending direction phase of the bending direction and the place circular arc of bridgeware 7702 of the place circular arc of supercilium connector 7701 Instead；So that the center of circle of two bridgewares 7702 is located in permanent opening 771 respectively, the center of circle of supercilium connector 7701 is positioned at fixation Outside opening 771, and then the structure for making to be made up of supercilium connector 7701 and two bridgewares 7702 is the structure of toe-in.This Sample, it can not only allow what light shield device more fastened to be fixed on virtual reality device, in use for some time, can also prevent Only front end retainer ring 77 is deformed and tilted upward, and influences the stability of front end retainer ring 77.Further, shading group can also be allowed Part combined with virtual reality device after seem more frivolous in appearance.

Because two bridgewares 7702 are respectively near the temple of user, illustrate between two bridgewares 7702 away from It is close from the facial width of user.Therefore, other portions of restriction are used as using the distance between central point C of two bridgewares 7702 The standard of part length.

Because the capitiform of each user is different, or the age bracket of user is different so that the facial width of each user is not Together, therefore, the distance between central point C of two bridgewares 7702 can also change.Under normal circumstances, the face of adult Width is about between 13cm~20cm, and the facial width of minor is about between 10cm~15cm, it is seen then that most common face Portion's width is between 13cm~15cm.The distance between the central point C of i.e. two bridgewares 7702 L2 10cm~20cm it Between change, it is preferred that distance L2 is optimum size between 13cm~15cm.

And in order to realize transitional function, bridgeware 7702 needs that the bending of wide-angle is presented, and based on facial width Limitation, it is desirable to which the angle theta 2 between tangent line at two end points of bridgeware 7702 changes between 60 °~80 °.

In order to embody transitionality, the radius of curvature of bridgeware 7702 is gradually reduced by one end to central point C, by central point C Gradually increase to the other end.The radius of curvature of bridgeware 7702 is six points of distance L2 between two central point C of bridgeware 7702 One of change between a quarter；The distance between two end points of bridgeware 7702 L3 accounts for two central points of bridgeware 7702 The 15%~30% of distance L2 between C.

For example, distance L2 changes between 10cm~20cm, when the radius of curvature of bridgeware 7702 is the six of distance L2 When/mono-, then the radius of curvature of bridgeware 7702 changes between 1.67cm~3.33cm, i.e., the radius of curvature at end points For 3.33cm, the radius of curvature at central point C is 1.67cm；When four points that the radius of curvature of bridgeware 7702 is distance L2 For the moment, then the radius of curvature of bridgeware 7702 changes between 2.5cm~5cm, i.e., the radius of curvature at end points is 5cm, Radius of curvature at central point C is 2.5cm；When the radius of curvature of bridgeware 7702 is 1/5th of distance L2, then The radius of curvature of bridgeware 7702 changes between 2cm~4cm, i.e., the radius of curvature at end points is 4cm, at central point C Radius of curvature be 2cm.As can be seen here, radius of curvature of the bridgeware 7702 at end points changes between 3.33cm~5cm, The radius of curvature of central spot changes between 1.67cm~2.5cm.

The distance between two end points of bridgeware 7702 L3 accounts for the 15%~30% of distance L2, and according to bridgeware 7702 radius of curvature, the size and degree of crook of bridgeware 7702 can be limited, realize that the transition of bridgeware 7702 is made according to this With.For example, when distance L3 accounts for the 15% of distance L2, distance L3 can use any value between 1.5cm~3cm；Work as distance When L3 accounts for the 30% of distance L2, distance L3 can use any value between 3cm~6cm；When distance L3 accounts for the 20% of distance L2 When, distance L3 can use any value between 2cm~4cm；When distance L3 accounts for the 25% of distance L2, distance L3 can be used Any value between 2.5cm~5cm.Preferably, when distance L3 accounts for the 23.35% of distance L2, to be optimal apart from accounting, Now, distance L3 can use any value between 2.335cm~4.67cm.And due to human body face width 13cm~ It is most suitable size between 15cm, therefore the size that distance L3 is chosen between 3.0355cm~3.5025cm is optimum chi It is very little；Particularly, it is most common width when human body face width is 14cm, now distance L4 is 3.269cm.

Because the radian of supercilium connector 7701 and two superciliums of user are related, and in order that the energy of supercilium connector 7701 Enough pedestal effects for playing higher degree, therefore, the radian of supercilium connector 7701 is without excessive.The arc of supercilium connector 7701 Degree angle theta 1 between the tangent line at two end points of supercilium connector 7701 represents.In the present embodiment, angle theta 1 is bridge joint 2 times~2.9 times of angle theta 2 between tangent line at two end points of part 7702.Because angle theta 2 changes between 60 °~80 °, Therefore, angle theta 1 changes between 140 °~174 °.For example, when angle theta 2 is 75 °, angle theta 1 is 2.28 times of angle theta 2 When, the angle of angle theta 1 is 171 °；When angle theta 2 is 60 °, when angle theta 1 is 2.9 times of angle theta 2, the angle of angle theta 1 is 174°；When angle theta 2 is 70 °, when angle theta 1 is 2 times of angle theta 2, the angle of angle theta 1 is 140 °.

The length of supercilium connector 7701, it is the distance between two end points L1.In order that supercilium connector 7701 With optimal stability, pedestal effect is played, the length of supercilium connector 7701 can not be too short, in order to avoid other portions can not be born The weight of part, unnecessary waste is caused without long.In the present embodiment, distance L1 accounts for two central points of bridgeware 7702 The 50%~75% of distance L2 between C.

For example, when distance L1 accounts for the 50% of distance L2, distance L1 can use any value between 5cm~10cm；When When distance L1 accounts for the 75% of distance L2, distance L1 can use any value between 7.5cm~15cm；When distance L1 accounts for distance L2 55% when, distance L1 can use 5.5cm~11cm between any value；When distance L1 accounts for the 60% of distance L2, distance L1 can use any value between 6cm~12cm；When distance L1 accounts for the 65% of distance L2, distance L1 can use 6.5cm~ Any value between 13cm；When distance L1 accounts for the 70% of distance L2, distance L1 can use any number between 7cm~14cm Value.Preferably, when distance L1 accounts for the 68.57% of distance L2 to be optimal apart from accounting, now, distance L1 can be used Any value between 6.857cm~13.714cm.And because the width of human body face is most suitable between 13cm~15cm Size, therefore distance L1 choose 8.9141cm~10.2855cm between size be optimum size, i.e., when distance L2 is During 13cm, distance L1 uses 8.9141cm, and when distance L2 is 14cm, distance L1 uses 10.2855cm；Particularly, human body is worked as It is most common width when facial width is 14cm, now distance L1 is 9.5998cm.

Support member 7703 plays a part of supporting pedestal in the structure of whole front end retainer ring 77 by changeover portion, i.e., logical Cross bridgeware 7702 and support supercilium connector 7701, so that whole front end retainer ring 77 has good stability.In use, Support member 7703 is corresponding with the face of user, in order to be adapted with the radian of user face, the degree of crook of support member 7703 Degree of crook than bridgeware 7702 is some larger.

One end of each support member 7703 connects the other end of a bridgeware 7702, bridgeware 7702 and support member respectively 7703 tie point is the inscribe intersection point of two circular arcs, illustrates the bending direction and bridgeware 7702 of the place circular arc of support member 7703 The bending direction of place circular arc is identical；The center of circle of two support members 7703 is located in permanent opening 771；Each support member 7703 The other end connects the both ends of nose connector 7704 jointly, and the arch summit of nose connector 7704 is close to supercilium connector 7701。

The radius of curvature of support member 7703 distance L2 between two central point C of bridgeware 7702 a quarter is to three points One of between change；The distance between two end points of support member 7703 L4 accounts for distance between two central point C of bridgeware 7702 The 25%~40% of L2.

The radius of curvature of support member 7703 is more than the radius of curvature of bridgeware 7702, so that support member 7703 has preferably Support force, it is easy to support supercilium connector 7701.Therefore, the distance between two end points of support member 7703 L4 accounts for distance L2's 25%~40%, and the radius of curvature of support member 7703, you can the size and degree of crook of support member 7703 are limited, it is real according to this The supporting role of existing support member 7703.

On the size of the radius of curvature of support member 7703, for example, because distance L2 is in 10cm~20cm anaplasia Change, when the radius of curvature of support member 7703 is distance L2 a quarter, the radius of curvature of support member 7703 2.5cm~ Change between 5cm, i.e., the radius of curvature at end points is 5cm, is 2.5cm in the radius of curvature of central spot；Work as support member 7703 radius of curvature be distance L2 1/3rd when, then the radius of curvature of support member 7703 3.33cm~6.67cm it Between change, i.e., the radius of curvature at end points is 6.67cm, is 3.33cm in the radius of curvature of central spot；And due to people's dignity The width in portion is most suitable size between 13cm~15cm, and now, the radius of curvature of support member 7703 is in 4.33cm~5cm Between change；Particularly, it is the radius of curvature of most common width, now support member 7703 when human body face width is 14cm For 4.67cm.

On the size of distance L4 between two end points of support member 7703, for example, when distance L4 accounts for the 25% of distance L2 When, distance L4 can use any value between 2.5cm~5cm；When distance L4 accounts for the 30% of distance L2, distance L4 can be used Any value between 3cm~6cm；When distance L4 accounts for the 35% of distance L2, distance L4 can be used between 3.5cm~7cm Any value；When distance L4 accounts for the 40% of distance L2, distance L4 can use any value between 4cm~8cm.Preferably, When distance L4 accounts for the 33.64% of distance L2, to be optimal apart from accounting, now, distance L4 can use 3.364cm~ Any value between 6.728cm.And because the width of human body face is most suitable size between 13cm~15cm, therefore The size that distance L4 is chosen between 4.3732cm~5.046cm is optimum size；Particularly, when human body face width is 14cm When be most common width, now distance L4 is 4.7096cm.

Nose connector 7704 is used as another changeover portion, the nose phase with user in the structure of whole front end retainer ring 77 It is corresponding, by domes, the nose of user can be fixed on.The both ends of nose connector 7704 connect a support member respectively 7703, certain supporting function can be played to support member 7703, so that support member 7703 plays good support force.

Supercilium connector 7701, nose connector 7704, bridgeware 7702 and support member 7703 are successively according to mentioned above principle Connection, form the loop configuration of closure, as front end retainer ring 77.In use, each part plays the function of itself, And between two neighboring part function mutual collaboration, can make front end retainer ring 77 that there is good stability, prevent front end Retainer ring 77 in use, deforms because of the influence of external forces, causes closing space to be destroyed, and loses light shield device The effect of shading is gone, influences the using effect of virtual reality device.

Supercilium connector 7701, nose connector 7704, bridgeware 7702 and support member 7703 by support ring 772, connection Ring 773 and locking ring 774 are divided into six parts, i.e. each section includes support ring 772, the connection ring being sequentially connected respectively 773 and the part-structure of locking ring 774 so that supercilium connector 7701, nose connector 7704, bridgeware 7702 and support member 7703 shape of cross section is respectively spill.

Specifically, as shown in figure 31, nose connector 7704 is included respectively in the first connecting portion 77041 of arc-shaped, the One bending section 77042, the second bending section 77043 and second connecting portion 77044；

First connecting portion 77041 and second connecting portion 77044, and, the first bending section 77042 and the second bending section 77043 are respectively symmetrically set so that 7704 symmetrical structure of nose connector.
