Figure 25 is the separate structure schematic diagram of light shield device provided by the present application；Figure 26 is light shield device provided by the present application Perspective view.

5 and Figure 26 referring to fig. 2, the application provide a kind of light shield device for virtual reality device, which is Cover structure, for being fixedly mounted with virtual reality device.When user wears virtual reality device experiencing virtual environment, shading Component can provide enclosure space.The light shield device includes：Shading piece 78 and front end fixed ring 77；Wherein, one end of shading piece 78 Equipped with connection opening 781, front end fixed ring 77 and shading piece 78 pass through 781 connection of connection opening.

Front end fixed ring 77 is built in the outermost of shading piece 78, when light shield device is applied to virtual reality device main body When, cooperated using the structure of front end fixed ring 77 and the body front end of virtual reality device, wraps up front end fixed ring 77 Firmly main body is fixedly mounted with realizing, and then maintains the face of light shield device, the main body of virtual reality device and user for a long time Enclosure space, so that user can long-time experiencing virtual environment.

For example, the structure of front end fixed ring 77 and the mirror body front end of VR glasses are tied when virtual reality device is VR glasses Structure is identical, and front end fixed ring 77 can be made to surround the frame portion of VR glasses, realizes that the long-time of light shield device and frame is fixed.Cause This, is when user wears the VR glasses for having light shield device, when light shield device will not be because wearing, work that user's face generates it Firmly, fall off from the frame of VR glasses, so realize light shield device maintain close tight purpose for a long time.

In a kind of optional embodiment, front end fixed ring 77 can be solid construction.I.e. in the outer of front end fixed ring 77 Chamfered shape is identical as the body profile shape of virtual reality device, and, the Internal periphery structure composition of front end fixed ring 77 with Under the premise of the body front end structure of virtual reality device is identical, remaining position is all made of plate structure.In use, front end is fixed Ring 77 can be completely covered on the front housing 1 of virtual reality device.

In another optional embodiment, engraved structure is also can be used in front end fixed ring 77.As shown in figure 25, front end The outer contour shape of fixed ring 77 is identical as the body profile shape of virtual reality device, and, the lubrication groove of front end fixed ring 77 Wide structure composition is identical as the body front end structure of virtual reality device, and the rest part of front end fixed ring 77 is hollow structure. In use, front end fixed ring 77 to be only fixed on to the body front end of virtual reality device, the centre of front end fixed ring 77 can The front housing 1 of virtual reality device is exposed.

When front end fixed ring 77 is using engraved structure, front end fixed ring 77 generates a permanent opening 771 immediately.Fixation is opened Mouthfuls 771 shape is identical as the shape of connection opening 781 of shading piece 78, and the two communicates, in order to front end fixed ring 77 and Shading piece 78 is fixedly mounted.

In order to which front end fixed ring 77 can be fully wrapped around firmly by the body front end of virtual reality device, avoid generating gap, make Wearing process easily gets loose phenomenon, it is desirable that the shape of front end fixed ring 77 need to be with the outside shape of virtual reality device body front end Shape is identical.It is understood that if the shape of virtual reality device body front end is rectangle, square and other differences When the shape of rule, then the shape of front end fixed ring 77 needs corresponding change.For example, the body front end when virtual reality device is selected It selects with certain radian and when form corresponding with glasses form, the shape of front end fixed ring 77 is preferably also glasses form, I.e. the shape of front end fixed ring 77 is depending on the shape of virtual reality device main body outer ledge.

It should be noted that front end fixed ring 77 disclosed herein, can both use engraved structure, reality can also be used Body structure, but in order to save material, mitigating the weight of virtual reality device and improve the Experience Degree of user, front end is fixed Ring 77 is preferably engraved structure.

Shading piece 78 has the hollow region for accommodating virtual reality device main body, and the connecting pin of shading piece 78 is equipped with connection and opens Mouth 781, for being fixedly connected with front end fixed ring 77, therefore, the shape phase of the shape and front end fixed ring 77 of connection opening 781 Together.The one end corresponding with connecting pin of shading piece 78 is for the facial contact with user, and to be formed and sealed with user's face using end Close space.

When light shield device provided by the present application is installed on virtual reality device, void is wrapped using front end fixed ring 77 Quasi- real world devices body front end, the shading piece 78 that recycling is connected with front end fixed ring 77 wrap its of virtual reality device Remaining part position, i.e. the main body viewing side of virtual reality device.Therefore, so that shading piece 78 connects the front end portion of front end fixed ring 77 Wrap the main body of virtual reality device, the rear end part of shading piece 78 and the viewing side of virtual reality device and user Face forms enclosure space.It can be seen that the light shield device that the structure of light shield device provided by the present application and the prior art provide Difference, and the mounting means of the two is also different.

The light shield device that the prior art provides is only hood-like structure, the knot without front end fixed ring 77 provided by the present application Structure.When installation, one end of light shield device is connected with the viewing side of virtual reality device, and the face of the other end and user, which are formed, to be sealed Close space.But since user is in experiencing virtual actual environment, need to use virtual reality device for a long time.And when wearing, User's face and light shield device can squeeze light shield device when contacting, and apply active force to light shield device, generate light shield device The trend being displaced outwardly causes the connection of the viewing side of light shield device and virtual reality device to loosen, and then leads to shading Component falls off from virtual reality device.This will affect enclosure space and cannot maintain for a long time, and then cannot be guaranteed that user can be with Long-time experiencing virtual actual environment, influences the using effect of virtual reality device.

And light shield device provided by the present application makes front end fixed ring using the cooperation of front end fixed ring 77 and shading piece 78 77 cooperate with the structure of the body front end of virtual reality device, and the feature being mutually fitted into using the two structure reaches stable company It connects.Using the mounting means of fully wrapped around virtual reality device, it is firmly secured at light shield device on virtual reality device, no It will appear the case where light shield device easily loosens in the prior art, and then user made to wear virtual reality device experiencing virtual environment When, enclosure space can be maintained for a long time, prevented the eyes of ambient interference user, allow user's preferably experiencing virtual Actual environment avoids the visual effect for influencing user.

In order to enable front end fixed ring 77 to be firmly secured at the body front end of virtual reality device, front end is needed to fix Ring 77 has unique structure.In the present embodiment, by front end fixed ring 77 using for engraved structure, referring to fig. 27, it illustrates The specific structure of bright front end fixed ring 77.

Specifically, front end fixed ring 77 includes support ring 772, and connection similar with the shape of support ring 772 respectively Ring 773 and locking ring 774.Support ring 772 plays the role of fixed shading piece 78 for connecting with shading piece 78；Locking ring 774 for fixing the frame 301 of virtual reality device, plays the role of locking, prevents light shield device and virtual reality device Junction is got loose；Connection ring 773 is for connecting support ring 772 and locking ring 774, the front end fixed ring 77 for forming three With stable structure.

Support ring 772, connection ring 773 and locking ring 774 have similar shape, i.e. the shape of three is same shape Shape, difference are only that the size of three is slightly different.It should be noted that support ring 772, connection ring 773 and locking ring 774 3 Person is similar to the main body outer contour shape of virtual reality device, for example, having when the body front end of virtual reality device uses When the corresponding shape of the glasses form of certain radian, the shape of support ring 772, connection ring 773 and locking ring 774 is it is also preferred that eye Mirror shape.

Since support ring 772 is contacted with virtual reality device main body outer ledge, the size of support ring 772 is maximum； And locking ring 774 is contacted with virtual reality device with the part that front housing 1 is connected, therefore, the size of locking ring 774 is minimum；Even Ring 773 is connect for connecting support ring 772 and locking ring 774, therefore, the size of connection ring 773 between support ring 772 size and Between the size of locking ring 774.

The connection relationship of support ring 772, connection ring 773 and locking ring 774 is specific as shown in (a) and (b) in Figure 28.

From in Figure 28 in (a) as can be seen that the cross-sectional shape of support ring 772 is close to rectangle, connection ring 773 it is transversal Face shape is close to isosceles trapezoid, and there are two the pentagons at right angle close to tool for the cross-sectional shape of locking ring 774.

The side 7721 of support ring 772 is connect with the side 7732 of connection ring 773, i.e., rectangular short side and isosceles trapezoid Bevel edge be connected so that support ring 772 and the angled connection of connection ring 773, that is, form strut angle α 1.Connection ring 773 it is another Side 7731 is connect with the side 7742 of locking ring 774, i.e. another bevel edge of isosceles trapezoid and pentagonal two right angles is common Right-angle side be connected so that connection ring 773 and the angled connection of locking ring 774, that is, form lock angle β 1.

In a kind of optional embodiment, the outer surface 7723 of support ring 772 and the outer surface 7733 of connection ring 773 connect It connects, and, the outer surface 7733 of connection ring 773 is connect with the outer surface 7743 of locking ring 774, the connection side between adjacent pairs The mode of round and smooth connection can be used in formula, so that junction is in arc-shaped, alternatively, by the way of being directly connected to, so that junction There are corner angle.No matter any connection type is used, does not influence support ring 772 and connection ring 773 and 773 and of connection ring Locking ring 774 is fixedly connected.The inner surface 7724 of support ring 772 is connect with the inner surface 7734 of connection ring 773, and connection The inner surface 7734 of ring 773 is connect with the inner surface 7744 of locking ring 774, likewise, the connection type of adjacent pairs' inner surface It can refer to the connection type of outer surface；Or in actual use, the connection type of inner surface may further reference virtual reality device The structure of body front end, in order to which the structure of front end fixed ring 77 and the body front end of virtual reality device cooperates.

In another optional embodiment, the inner surface 7724 of support ring 772 and the inner surface 7734 of connection ring 773 Connection type and connection ring 773 inner surface 7734 and locking ring 774 inner surface 7744 connection type still reference Above description, and the outer surface 7723 of support ring 772 and the outer surface 7733 of connection ring 773 can be not attached to together, Yi Jilian The outer surface 7733 for connecing ring 773 and the outer surface 7743 of locking ring 774 can also be not attached to together, even if front end fixed ring 77 Inner surface connection, the structure that outer surface disconnects is presented.The outer surface of support ring 772 and connection ring 773 disconnects degree, and connection The outer surface of ring 773 and locking ring 774 disconnects degree, being not specifically limited, being fixed in the present embodiment with can satisfy front end The stability of ring 77.

It is obtuse angle that support ring 772 and connection ring 773, which are formed by strut angle α 1, is used to support the main body of virtual reality device Front-end architecture；It is obtuse angle that connection ring 773 and locking ring 774, which are formed by lock angle β 1 also, for being arranged when front end fixed ring 77 In the body front end of virtual reality device, locking effect is played, prevents the body front end of virtual reality device from fixing in front end The medial movement of ring 77.Using the mutual cooperation of strut angle α 1 and lock angle β 1, increase the degree of locking, it can be by virtual reality The body front end of equipment is steadily locked in front end fixed ring 77, prevents front end fixed ring 77 easily from virtual reality device On fall off.

In the present embodiment, the angle of strut angle α 1 and lock angle β 1 occurs with 7733 width of outer surface of connection ring 773 Variation includes two kinds of situations that is, when 7733 width of the outer surface of connection ring 773 increases at this time：One is inclining for connection ring 773 Rake angle is constant, and connection ring 773 is moved along the direction of virtual reality device, while making the outer of support ring 772 and locking ring 774 Face width changes respectively, and the angle of strut angle α 1 and lock angle β 1 are constant at this time.It is for second the inclination of connection ring 773 Angle changes, at this point, changing inclining for connection ring 773 when being fixed point with the junction of support ring 772 and connection ring 773 Rake angle, so that strut angle α 1 becomes smaller, lock angle β 1 increases；When with the junction of connection ring 773 and locking ring 774 be fixed point When, strut angle α 1 becomes larger at this time, and lock angle β 1 becomes smaller.When the width of the outer surface of connection ring 773 7733 reduces, equally include Two kinds of situations, when the first situation, the angle of strut angle α 1 and lock angle β 1 are constant；When second situation, strut angle α 1 and lock The angle change rule and above-mentioned second situation for determining angle beta 1 are on the contrary, details are not described herein again.

The angle ratio of strut angle α 1 and lock angle β 1 is 0.8~1.25.In the present embodiment, strut angle α 1 and lock angle β 1 Angular range between 120 °~150 °, and with the variation of 7733 width of the outer surface of connection ring 773, strut angle α 1 And the angle ratio of lock angle β 1 changes between 0.8~1.25.For example, strut angle α 1 is when angle ratio is 0.8 120 °, lock angle β 1 be 150 °.When angle ratio is 0.9, strut angle α 1 is 130 °, lock angle β 1 is 145 °；Alternatively, 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 °.It preferably, is optimal angle ratio when angle ratio is 0.97, strut angle α 1 is 133 °, lock angle β 1 at this time It is 137 °.When strut angle α 1 and lock angle β 1 is using optimal angle, support ring 772, connection ring 773 and locking ring can be made The structure of 774 formation is more stable.

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

In the present embodiment, restricts angle and strut angle α 1 and lock angle β 1 meets such as following formula relationship：

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

Restrict the degree that angle is used to limit the outward opening extension of concave forward end fixed ring 77.If the angle for restricting angle is got over Greatly, illustrate that the extent of opening of front end fixed 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 fixed ring 77 cooperates, so that the outer rim of the body front end of virtual reality device also approaches one Shape.When user wears the virtual reality device experiencing virtual environment for having light shield device, light shield device can be generated to user The tightening force in facial direction, and since the outer rim of front end fixed ring 77 and body front end all approaches plane, so that front end fixed ring 77 slide in the body front end of virtual reality device to the direction of tightening force, and then front end fixed ring 77 are caused not consolidate for a long time It is scheduled on the body front end of virtual reality device, influences the using effect of virtual reality device.

If the angle for restricting angle is smaller, illustrates that the extent of opening of front end fixed ring 77 is smaller, i.e., V-arrangement is gradually presented.And Since the body front end structure of virtual reality device and the inside structure of front end fixed 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 front housing 1 of virtual reality device contacts, and the outer surface of front housing 1 is concordant with the front end surface of virtual reality device, and in order to make The body front end of virtual reality device and the interior side-to-side anastomosis of front end fixed ring 77 are fixed, so that the width of locking ring 774 reduces.And The width of locking ring 774 is smaller, then is unable to give full play the function of its locking, causes when wearing, because coming from user's face side To the effect of tightening force easily make light shield device so that front end fixed ring 77 falls off from the front end of virtual reality device With loosening in the process from the front end of virtual reality device, and then enclosure space can not be maintained for a long time, influence virtual reality device Using effect.

Therefore, in order to enable light shield device to be firmly secured at the body front end of virtual reality device, need to limit system About the angle at angle cannot be excessive, can not be too small.Again since the size for restricting angle is related 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 the angle and formula (1) of above-mentioned strut angle α 1 and lock angle β 1, limits restriction angle and change between 80 °~110 °.It is preferred that , when restricting angle is 90 °, i.e., support ring 772 and locking ring 774 are in state is mutually perpendicular to, and under such state, front end is fixed The degree of the outward opening extension of ring 77 is best, before light shield device being enable to be firmly secured at the main body of virtual reality device End.

From can be seen that in (a) in Figure 28, the another side 7741 of locking ring 774 is equipped with inclined ring 7740, inclined ring 7740 Two sides connect respectively with the inner surface 7744 of locking ring 774 and side 7741.The setting of inclined ring 7740 can not only with will be whole Body component is made into entity compared to mitigating weight, moreover it is possible to when light shield device and virtual reality device come into full contact with, allow light shield device It is lofty compared with the contact position of virtual reality device is unlikely to seem there are a transition, it allows its appearance to seem more to coordinate, increases Add the aesthetic feeling of light shield device.

Inclined ring 7740 is used to make to form chamfering, i.e. inclined ring 7740 and interior table at the another side 7741 of locking ring 774 The extended line in face 7744 forms half chamfering γ；The half chamfering γ is used to wrap virtual reality device master when front end fixed ring 77 It when body front end, can prevent the inner surface 7744 of locking ring 774 and the front housing 1 of virtual reality device from interfering, it is solid to influence front end Determine the stability of ring 77, and then can avoid the active force that front housing 1 generates locking ring 774, and makes front end fixed ring 77 that pine occur De- phenomenon.

In order to form half chamfering γ, needing the tilt angle of inclined ring 7740 to change between 0 °~90 ° (does not include endpoint 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 entire design full of aesthetic feeling, optimal angle model Enclosing is 30 °~60 °, the especially angle within the scope of 40 °~50 °, specifically such as 45 °.

In terms of another angle, the width H1 of inclined ring 7740 is the 30%~80% of 774 thickness δ 1 of locking ring, can also Illustrate that half chamfering γ is acute angle, i.e. 7744 width of inner surface of locking ring 774 can just prevent from locking less than the width of outer surface 7743 The front housing 1 of the inner surface 7744 and virtual reality device of determining ring 774 interferes.The thickness δ 1 of locking ring 774 is greater than inclined ring 7740 width, it is ensured that inclined ring 7740 is hardly damaged while reducing weight, because if blocked up, may cause inclination 7740 weight of ring increases, and then the weight for increasing whole light shield device will lead to inclined ring 7740 and be easily damaged if excessively thin, User is not easy to be used for multiple times.

From can be seen that in (b) in Figure 28, support ring 772, connection ring 773 and locking ring 774 are sequentially connected, and fix front end The spill of outward opening extension is presented in the cross-sectional shape of ring 77, fixes in order to which virtual reality device is successfully mounted on front end The inside of ring 77, and front end fixed ring 77 is made to be firmly secured at the body front end of virtual reality device.

In order to reduce receiving pressure when user wears virtual reality device, show user virtually in extended wear The influence of real weight of equipment needs to reduce the weight of light shield device entirety as far as possible.So, the weight of front end fixed ring 77 is reduced Amount, can reduce the weight of whole light shield device to a certain degree.While reducing 78 overall weight of shading piece, before also needing guarantee 772 intensity of support ring of fixed ring 77 is held, in order to which user will not be damaged easily when using shading piece 78.And in order to The fixed shading piece 78 of the inner surface 7724 of ring 772 easy to support needs the inside of support ring 772 there are a fixed gap, gap Size is related with the thickness of shading piece 78.

Therefore, as shown in figure 29, the side 7721 of 772 inner surface 7724 of support ring is equipped with for withstanding support ring 772 Rib ring 775；The width that the rising height of rib ring 775 as interspaces in advance.The other side 7722 of 772 inner surface 7724 of support ring Equipped with the fastening zone 776 for fixing shading piece 78；Rib ring 775 and fastening zone 776 are respectively along the inner surface 7724 of support ring 772 It is formed continuously, i.e., the inner surface of support ring 772 is made of rib ring 775 and fastening zone 776.

It is that the pre- of shading piece 78 is installed to interspace since rib ring 775 is formed by gap, 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 775 reaction force of rib ring, prevent support ring 772 because can not It bears the support force of rib ring 775 and breakage occurs, therefore, it is necessary to the thickness δ 2 of support ring 772 is high much larger than the protrusion of rib ring 775 Spend H2.In the present embodiment, the rising height H2 and the optimal proportion relationship of 772 thickness δ 2 of support ring of rib ring 775 are：Rib ring 775 rising height H2 is the 25%~30% of 772 thickness δ 2 of support ring.

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 Playing height H2 is 4.48mm；It preferably, is optimal thickness ratio when thickness ratio is 27%, the rising height of rib ring 775 at this time H2 is 4.32mm.Optimal thickness ratio can make support ring 772 have enough endurance, be generated to it with to bear rib ring 775 While support force, the weight of light shield device is reduced as far as possible, prevents the thickness of support ring 772 excessively thick and heavy and increases light shield device Weight.Overweight light shield device can apply biggish pressure to the face of user, influence user experience；And overweight shading Component can make virtual reality device generate the trend to downslide, influence the using effect of virtual reality device.

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

77 structure of front end fixed ring from angle, the i.e. front view of front end fixed ring 77 such as Figure 30 institute are used from user Show, front end fixed ring 77 further includes being in the supercilium connector 7701 of arc-shaped, nose connector 7704, two of domed shape The bridgeware 7702 of arc-shaped and two supporting elements 7703 in arc-shaped.

Supercilium connector 7701 plays the role of pedestal in the structure of entire front end fixed 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 related with two superciliums of user, i.e. eyebrow Angle theta 1 is related to two superciliums of user between tangent line at two endpoints of portion's connector 7701.

Bridgeware 7702 plays the role of transition in the structure of entire front end fixed ring 77, i.e., by the supercilium as pedestal The both ends of connector 7701 are transitioned on supporting element 7703, and limit the length of supercilium connector 7701, so that front end fixed ring 77 keep stable structure.Therefore, it is necessary to the bending degree of bridgeware 7702 is more larger, so that the two of supercilium connector 7701 End can successfully be turned 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 are connected 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 of 7701 place circular arc of supercilium connector and the bending direction of 7702 place circular arc of bridgeware On the contrary；So that the center of circle of two bridgewares 7702 is located in permanent opening 771, the center of circle of supercilium connector 7701 is located at solid Surely outside opening 771, and then make the structure for the structure toe-in being made of supercilium connector 7701 and two bridgewares 7702. It, in use for some time, can be in this way, can not only allow what light shield device more fastened to be fixed on virtual reality device It prevents front end fixed ring 77 from deforming and tilting upward, influences the stability of front end fixed ring 77.Further, shading can also be allowed Component combined with virtual reality device after seem more frivolous in appearance.

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

Since 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 the central point C of two bridgewares 7702 can also change.Under normal conditions, 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 that transitional function, bridgeware 7702 need to present the bending of wide-angle, and based on facial width Limitation, it is desirable that the angle theta 2 between tangent line at two endpoints 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 It is gradually increased to the other end.The radius of curvature of bridgeware 7702 is six points of distance L2 between two 7702 central point C of bridgeware One of change between a quarter；The distance between two endpoints of bridgeware 7702 L3 accounts for two 7702 central points of bridgeware 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 endpoint For 3.33cm, the radius of curvature at central point C is 1.67cm；When the radius of curvature of bridgeware 7702 is the four of distance L2 When/mono-, then the radius of curvature of bridgeware 7702 changes between 2.5cm~5cm, i.e., the radius of curvature at endpoint is 5cm, the radius of curvature at central point C are 2.5cm；When the radius of curvature of bridgeware 7702 is 1/5th of distance L2 When, then the radius of curvature of bridgeware 7702 changes between 2cm~4cm, i.e., the radius of curvature at endpoint is 4cm, at center Radius of curvature at point C is 2cm.It can be seen that radius of curvature of the bridgeware 7702 at endpoint is between 3.33cm~5cm Variation, changes between 1.67cm~2.5cm in the radius of curvature of center.

The distance between two endpoints of bridgeware 7702 L3 accounts for the 15%~30% of distance L2, and according to bridgeware 7702 radius of curvature can limit the size and bending degree of bridgeware 7702, realize that the transition of bridgeware 7702 is made according to this With.For example, any value between 1.5cm~3cm can be used in distance L3 when distance L3 accounts for the 15% of distance L2；Work as distance When L3 accounts for the 30% of distance L2, any value between 3cm~6cm is can be used in distance L3；When distance L3 accounts for the 20% of distance L2 When, any value between 2cm~4cm can be used in distance L3；When distance L3 accounts for the 25% of distance L2, distance L3 be 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, At this point, any value between 2.335cm~4.67cm can be used in distance L3.And due to the width of human body face 13cm~ It is most suitable size between 15cm, therefore it is optimum ruler that distance L3, which chooses the size between 3.0355cm~3.5025cm, It is very little；It particularly, is most common width when human body face width is 14cm, distance L4 is 3.269cm at this time.

Since the radian of supercilium connector 7701 and two superciliums of user are related, and in order to enable 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 is indicated with angle theta 1 between the tangent line at two endpoints of supercilium connector 7701.In the present embodiment, angle theta 1 is bridge joint 2 times~2.9 times of angle theta 2 between tangent line at two endpoints of part 7702.Since angle theta 2 changes between 60 °~80 °, Therefore, angle theta 1 changes between 140 °~174 °.For example, angle theta 1 is 2.28 times of angle theta 2 when angle theta 2 is 75 ° 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, as the distance between two endpoint L1.In order to make supercilium connector 7701 With optimal stability, pedestal effect is played, the length of supercilium connector 7701 cannot be too short, in order to avoid other unbearable portions The weight of part causes unnecessary waste without too long.In the present embodiment, distance L1 accounts for two 7702 central points of bridgeware The 50%~75% of distance L2 between C.

For example, any value between 5cm~10cm can be used in distance L1 when distance L1 accounts for the 50% of distance L2；When When distance L1 accounts for the 75% of distance L2, any value between 7.5cm~15cm is can be used in distance L1；When distance L1 accounts for distance L2 55% when, any value between 5.5cm~11cm can be used in distance L1；When distance L1 accounts for the 60% of distance L2, distance Any value between 6cm~12cm can be used in L1；When distance L1 accounts for the 65% of distance L2, distance L1 can be used 6.5cm~ Any value between 13cm；When distance L1 accounts for the 70% of distance L2, any between 7cm~14cm is can be used in distance L1 Numerical value.Preferably, when distance L1 accounts for the 68.57% of distance L2 to be optimal apart from accounting, at this point, distance L1 can be used Any value between 6.857cm~13.714cm.And since 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 When 13cm, distance L1 uses 8.9141cm, and when distance L2 is 14cm, distance L1 uses 10.2855cm；Particularly, work as human body It is most common width when facial width is 14cm, distance L1 is 9.5998cm at this time.
