This application provides the light shield device of another virtual reality device, Figure 24 is the another of the embodiment of the present application offer The structural representation of the light shield device of kind virtual reality device.

Referring to Figure 24, the structural representation for another virtual reality device light shield device that the embodiment of the present application provides, with It is in place of the difference of above-described embodiment, light shield device 7 includes：Front end retainer ring 77 and shading piece 78.The light shield device 7 is cover Body structure, for being fixedly mounted with virtual reality device.When user wears virtual reality device experiencing virtual environment, shading group Part 7 can provide closing space.Wherein, front end retainer ring 77 is closing framework, is built in the outermost of shading piece 78, utilizes front end The respective outer side edges of retainer ring 77 and virtual reality device body front end, wrap virtual reality device main body, will actively hide Optical assembly 7 is fixed on virtual reality device.

As shown in figure 25, one end of shading piece 78 is initiating terminal 21a, and initiating terminal 21a is provided with connection and is open, front end retainer ring 77 one end is provided with permanent opening, and the initiating terminal 21a of shading piece 78 is by connecting opening and permanent opening and front end retainer ring 77 Connection, connection opening and permanent opening are of similar shape, and the two is communicated so that the light shield device 7 formed to be hollow and Stable structure.Shading piece 78 forms cut-off end 22a from initiating terminal 21a to the opposite side extension being connected with front end retainer ring 77, Cut-off end 22a has the terminal curve 23a of consecutive variations.

When wearing virtual reality device, cut-off end 22a is used to be bonded with the face of user, to form closing space, makes User can experience preferable visual effect.Terminal curve 23a changing rule is adapted with the face contour of user, to use Family can have preferable experience sense, avoid irregular profile and skin when wearing the virtual reality device with light shield device 7 When skin contacts, different degrees of extruding is caused, increases the pain of user, makes experience bad.Meanwhile regular terminal curve 23a, it can be bonded with the face perfection of user, gap will not be produced.Therefore, light shield device 7 can fully play shade function, keep away Exempt from ambient by gap to be entered, influence the visual effect of user.

In order that terminal curve 23a can be adapted with the face contour of user, it is desirable to which terminal curve 23a tools are well-regulated Changing rule.Specifically, terminal curve 23a has the first minimal point 231a and second on the central plane 50a of light shield device 7 Minimal point 232a；First minimal point 231a is located at the top of shading piece 78, with being contacted at the place between the eyebrows of user or the center of forehead；The Two minimal point 232a are located at the bottom of shading piece 78, near the bridge of the nose of user.

Distalmost end of the terminal curve 23a in central plane 50a both sides has two distal end limit 233a, two distal end limits 233a is symmetrical along central plane 50a, and distal end limit 233a is terminal curve 23a and the solstics of the distance of front end retainer ring 77.Far End limit 233a is located at the position that shading piece 78 is connected with temple, and with the contacts side surfaces of user's face, such as temple or ear Near.

As shown in figure 26, terminal curve 23a forms two between the first minimal point 231a and two distal end limit 233a Along the symmetrical first tune 234a of the central plane 50a.First tune 234a is located at the upper end of shading piece 78, outside in center The arc of extension；Two the first tune 234a tie point is the first minimal point 231a so that two the first curved tunes 234a connections and form smooth cambered surface.The cambered surface is presented that center is gentle, exists to the state being gradually curved at both ends, the i.e. cambered surface First minimal point 231a both sides convergence plane, is gradually curved from the first minimal point 231a to distal end limit 233a so that The shape of cambered surface is adapted with the forehead profile of user.The upper end of shading piece 78 has the cambered surface closed with user's forehead match profiles Structure, user can be made cosily to wear the virtual reality device with light shield device 7, avoided with other structures or irregular The shading piece 78 of structure influences the experience of user to producing constriction at user's forehead.Also, if shading piece 78 is in the first pole When structure at dot 231a can not match with user's forehead profile, seam is also easy to produce between shading piece 78 and user's forehead Gap, the close photosensitiveness of closing space is influenceed, and then influence the shaded effect of light shield device 7.

As shown in figure 28, terminal curve 23a forms two between the second minimal point 232a and two distal end limit 233a Along the symmetrical second tune 235a of central plane 50a.Second tune 235a is located at the lower end of shading piece 78, i.e., with user face and The position of nose contact, the arc to be extended internally in center.Two the second tune 235a tie point is the second minimal point 232a, So that two the second curved tune 235a connect to form smooth change cambered surface.Arch is presented in the change cambered surface at center Shape, to the state being gradually curved at two-end-point, i.e. arch is presented in the cambered surface at the second minimal point 232a, for being adapted to user's Nose, it is gradually curved from the second minimal point 232a between the limit 233a of distal end, for being adapted to the face of user so that whole to become Change cambered surface and w shapes are presented, be adapted with the face contour with user.The shape of change cambered surface is mutually fitted with the face of user and nose Match somebody with somebody, can be brought into close contact shading piece 78 and the face contour of user, avoid producing gap, to improve the shading of light shield device 7 effect Fruit.

As shown in figure 27, the first profile angle α of consecutive variations is formed between the first tune 234a and central plane 50a, the One profile angle α makes the first tune 234a and the distance of front end retainer ring 77 gradually increase along the direction away from central plane 50a.

The first profile angle α is used for the degree of crook for being limited to the cambered surface of the upper end of shading piece 78 formation so that the change of cambered surface Rule is adapted with the forehead profile of user.Because the first profile angle α angles gradually change so that the first tune 234a's Degree of crook gradually increase at the limit 233a of distal end from central plane 50a, and then make each point on the first tune 234a with before The gradually increase of the distance between retainer ring 77 is held, to adapt to the profile of user's face.Appropriate the first profile angle α can make shading piece The angle changing of 78 upper end cambered surfaces is adapted with the radian of user's forehead, and then makes light shield device 7 when in use, can with Family face is brought into close contact, and avoids the occurrence of gap, influences the shaded effect of light shield device 7.

Specifically, as shown in figure 29, because the cambered surface that the upper end of shading piece 78 is formed tends to be flat at the first minimal point 231a It is slow, so the first profile angle α forms maximum α 1 at the first minimal point 231a.In the present embodiment, preferred maximum α 1 is 86 Change between the degree of degree -90.When maximum α 1 is using 90 degree, the cambered surface that upper end is formed is plane, is slightly put down a bit suitable for forehead User；When maximum α 1 is using 86 degree, the cambered surface that upper end is formed is arc, and the user of any is slightly roused suitable for forehead；When When maximum α 1 is using 88 degree, the cambered surface that upper end is formed be arc, suitable for forehead occupy it is more gentle it is relatively bulging between user.

Due to the position that the structure at the limit 233a of distal end is connection temple, the side of this position and user's face is affixed Close, therefore, need to keep connecing subparallel state with central plane 50a provided with distal end limit 233a positions, and then make shading piece Position of 78 both sides provided with distal end limit 233a is relatively parallel, and forms concave structure with front end retainer ring 77, to be fastened on use The face at family, so the first profile angle α has minimum value α 2 at the limit 233a of distal end.In the present embodiment, preferred minimum value α 2 Change between 12 degree of -18 degree.When minimum value α 2 is using 12 degree, the extent of opening of the concave structure of formation is minimum, is applied to The relatively round user of head dummy；When minimum value α 2 is using 18 degree, the extent of opening of the concave structure of formation is maximum, suitable for head dummy compared with Flat user；When minimum value α 2 using 15 degree when, the extent of opening of the concave structure of formation is moderate, suitable for head dummy it is relatively round with User between more flat.

The first profile angle α is continuously reduced from the first minimal point 231a to distal end limit 233a directions so that on shading piece 78 Hold the degree of crook of the cambered surface formed that continuous change occurs so that shading piece 78 is provided with distal end limit 233a two positions It is parallel with respect to convergence, so that it forms concave structure with front end retainer ring 77, to adapt to the radian of user's face profile, ensure to hide The upper end of light part 78 is brought into close contact with user's face, avoids the occurrence of gap.

As shown in figure 30, shading piece 78 is formed from initiating terminal 21a to cut-off end 22a makes the presentation of shading piece 78 end convergence become The differential of the arc curve 24a of gesture；Convergent tendency is presented in shading piece 78 at the limit 233a of distal end, so that the both sides of shading piece 78 can clamp The facial both sides of user, and then can increase light shield device 7 and user's face is bonded tightness, avoids rocking because of user's head And the structure being close to originally is destroyed, so as to avoid producing gap.

Specifically, differential of the arc curve 24a forms convergency γ, convergency γ at the limit 233a of distal end with central plane 50a The limit distance L1 between two distal end limit 233a is set to be less than the ring width H1 of front end retainer ring 77.Worn for the ease of user, Limit distance L1 between two distal end limit 233a, the i.e. A/F of shading piece 78 can not excessively be less than front end retainer ring 77 Width H1, avoid because distance L1 is too small, user can not wear, or, cause shading piece 78 excessive to the clamping force of facial both sides, right Skin causes larger pressure, influences the experience of user.

Therefore, in the present embodiment, 92.5%-s of the limit distance L1 between two distal end limit 233a in ring width H1 is limited Between 97.5%.Distance L1 is accounted between width H1 92.5%-97.5%, can make two positions provided with distal end limit 233a When being bonded with user's face side, produce appropriate clamping force, tight feeling will not be both brought to user, also will not be because of user it is small Action and easily from face slide.It can be seen that appropriately distance accounting, it is possible to achieve light shield device 7 has with face when being bonded Appropriate clamping force, light shield device 7 is not produced pressure contact with user's face, constriction is not had, so as to improve user's Experience.

Because ring width H1 is adapted with the facial width of user, so in the present embodiment, being limited with the facial width of user Determine ring width H1.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, ring width H1 can also change.Under normal circumstances, the facial width of adult is about between 13cm~20cm, and not The facial width of adult is about between 10cm~15cm, it is seen then that most common facial width is between 13cm~15cm.I.e. Ring width H1 changes between 10cm~20cm, it is preferable that ring width H1 is optimum size between 13cm~15cm.

When distance L1 accounts for the 92.5% of ring width H1, distance L1 can use any value between 9.25cm~18.5cm； When distance L1 accounts for the 96% of ring width H1, distance L1 can use any value between 9.6cm~19.2cm；When distance L1 accounts for ring Wide H1 97.5% when, distance L1 can use 9.75cm~19.5cm between any value.Preferably, distance L1 accounts for ring width H1 95% when to be optimal apart from accounting, now, distance L1 can use any value between 9.5cm~19cm；And ring width H1 It is optimum size between 13cm~15cm, now, distance L1 can use any number between 12.35cm~14.25cm Value.

In addition, in order that shading piece 78 has enough length to be bonded with the face of user, it is necessary to which distal end limit 233a is with hiding The distance L2 of light part 78 is between ring width H1 50%-70%.

When distance L2 accounts for the 50% of ring width H1, distance L2 can use any value between 5cm~10cm；As distance L2 When accounting for the 60% of ring width H1, distance L2 can use any value between 6cm~12cm；When distance L2 accounts for the 70% of ring width H1 When, distance L2 can use any value between 7cm~14cm.Preferably, when distance L2 accounts for the 57.5% of ring width H1 for most It is good apart from accounting, now, distance L2 can use any value between 5.75cm~11.5cm；And ring width H1 13cm~ It is optimum size between 15cm, now, distance L2 can use any value between 7.475cm~8.625cm.

In order to further illustrate the first profile angle α changing rule, in the present embodiment, the first profile angle α is limited first Angle value α 3 at tune 234a distance center plane 50a a quarter ring widthes H1 is between 52 degree of -58 degree.The first profile angle Angle value αs 4 of the α at first 1/8th ring width H1 of tune 234a distance center planes 50a is between 75 degree of -80 degree；The One profile angle α angle value αs 5 of the first tune 234a at described 3/8ths ring width H1 of central plane 50a 29 degree- Between 35 degree.

In order to embody the rule of the first profile angle α consecutive variations, so that cambered surface and user plane that the upper end of shading piece 78 is formed Contouring is adapted, and when the first profile angle α maximum α 1 chooses 86 degree, α 4 chooses 75 degree, and α 3 chooses 52 degree, and α 5 chooses 29 Degree, minimum value α 2 choose 12 degree；When the first profile angle α maximum α 1 chooses 88 degree, α 4 chooses 78 degree, and α 3 chooses 55 degree, α 5 choose 32 degree, and minimum value α 2 chooses 15 degree；When the first profile angle α maximum α 1 chooses 90 degree, α 4 chooses 80 degree, and α 3 is selected 58 degree are taken, α 5 chooses 35 degree, and minimum value α 2 chooses 18 degree.

As shown in figure 31, the second profile angle beta of consecutive variations is formed between the second tune 235a and central plane 50a, the Two profile angle betas make the second tune 235a and the distance of front end retainer ring 77 continuously increase along the direction away from central plane 50a.

Second profile angle beta is used for the degree of crook for being limited to the change cambered surface of the lower end of shading piece 78 formation so that change arc The changing rule in face is adapted with the face of user and nose.Because the angle of the second profile angle beta gradually changes so that the The gradually increase, and then make two the second tunes at the limit 233a of distal end from central plane 50a of two tune 235a degree of crook 235a can be connected to form domes, be bonded with the nose with user, and the second tune 235a remainder is curved Qu Chengdu is identical with the radian of user face.The second appropriate profile angle beta can make the bending of the change cambered surface of the lower end of shading piece 78 Degree is adapted with the radian of user's face, and then makes light shield device 7 when in use, can be brought into close contact with user's face, Gap is avoided the occurrence of, influences the shaded effect of light shield device 7.

Specifically, because the change cambered surface that the lower end of shading piece 78 is formed forms domes at the second minimal point 232a, And the position being connected with domes is used to be bonded with face, so the second profile angle beta has at the second minimal point 232a Maximum β 1, in the present embodiment, maximum β 1 changes between 86 degree of -90 degree.When maximum β 1 is using 90 degree, lower end is formed Change cambered surface be plane, the user of any is slightly put down suitable for face；When maximum β 1 is using 86 degree, the change of lower end formation Cambered surface is arc, and the user of any is slightly roused suitable for face；When maximum β 1 is using 88 degree, the change cambered surface that lower end is formed is Arc, suitable for face occupy it is more gentle relatively rouse between user.

Because the structure at the limit 233a of distal end is the position of connection temple, the side with user's face is affixed herein Close, therefore, need to keep connecing subparallel state with central plane 50a provided with distal end limit 233a positions, and then make shading piece Position of 78 both sides provided with distal end limit 233a is relatively parallel, and forms concave structure with front end retainer ring 77, to be fastened on use The face at family, so the second profile angle has a minimum value β 2 at the limit 233a of distal end, in the present embodiment, preferred minimum value β 2 exists Change between 10 degree of -16 degree.When minimum value β 2 is using 10 degree, the extent of opening of the concave structure of formation is minimum, suitable for head The relatively round user of type；When minimum value β 2 is using 16 degree, the extent of opening of the concave structure of formation is maximum, more flat suitable for head dummy User；When minimum value β 2 using 13 degree when, the extent of opening of the concave structure of formation is moderate, suitable for head dummy it is relatively round with compared with User between flat.
