This application provides the light shield device of another virtual reality device, Figure 24 is provided by the embodiments of the present application another The structural schematic diagram of the light shield device of kind virtual reality device.

Referring to Figure 24, the structural schematic diagram of another kind virtual reality device light shield device provided by the embodiments of the present application, with It is in place of the difference of above-described embodiment, light shield device 7 includes：Front end fixed 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 Component 7 can provide enclosure space.Wherein, front end fixed ring 77 is closing framework, the outermost of shading piece 78 is built in, before utilization The respective outer side edges for holding fixed ring 77 and virtual reality device body front end, wrap virtual reality device main body, actively will Light shield device 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 equipped with connection and is open, front end fixed ring 77 one end is equipped with permanent opening, and the initiating terminal 21a of shading piece 78 is by connecting opening and permanent opening and front end fixed ring 77 Connection, connection opening and permanent opening are of similar shape, and the two communicates so that the light shield device 7 formed be it is hollow and Stable structure.Shading piece 78 extends from initiating terminal 21a to the other side being connect with front end fixed ring 77, forms cut-off end 22a, End the terminal curve 23a that end 22a has consecutive variations.

When wearing virtual reality device, cut-off end 22a is used to be bonded with the face of user, to form enclosure space, makes User can experience preferable visual effect.The changing rule of terminal curve 23a 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, the feeling of pain of user is increased, keeps experience bad.Meanwhile regular terminal curve 23a can be bonded with the face perfection of user, not will produce gap.Therefore, light shield device 7 can fully play shade function, keep away Exempt from ambient by gap to be entered, influences the visual effect of user.

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

There are two distal end pole 233a, two distal end poles for distalmost end tools of the terminal curve 23a in the both sides central plane 50a 233a is symmetrical along central plane 50a, and distal end pole 233a is the farthest point of terminal curve 23a and 77 distance of front end fixed ring.Far End pole 233a is located at the position that shading piece 78 is connect with temple, and is contacted with the side 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 pole 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；The tie point of two the first tune 234a is the first minimal point 231a so that two the first arc-shaped tunes 234a connections and form smooth cambered surface.The cambered surface present center it is gentle, to the state being gradually curved at both ends, i.e. the cambered surface exists The both sides of first minimal point 231a approach plane, are gradually curved from the first minimal point 231a to distal end pole 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 can make user cosily wear the virtual reality device with light shield device 7, avoid with other structures or irregular The shading piece 78 of structure influences the experience of user to generating constriction at user's forehead.Also, if shading piece 78 is in the first pole When structure at dot 231a can not be matched with user's forehead profile, seam is also easy to produce between shading piece 78 and user's forehead Gap influences the close photosensitiveness of enclosure space, and then influences 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 pole 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 extend internally in center.The tie point of two the second tune 235a is the second minimal point 232a, So that two the second arc-shaped tune 235a connect to form smooth variation cambered surface.Arch is presented in the variation 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 is gradually curved, the face for being adapted to user from the second minimal point 232a between the pole 233a of distal end so that entire to become Change cambered surface and w shapes are presented, to be adapted with the face contour of user.The shape of variation cambered surface is mutually fitted with the face of user and nose Match, shading piece 78 and the face contour of user can be made to fit closely, avoid generating gap, the shading to improve light shield device 7 is imitated 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 gradually increase along the direction far from central plane 50a at a distance from front end fixed ring 77.

The first profile angle α is used to be limited to the bending degree of the cambered surface of 78 upper end of shading piece formation so that the variation of cambered surface Rule is adapted with the forehead profile of user.Since the first profile angle α angles gradually change so that the first tune 234a Bending degree gradually increased from central plane 50a to from the pole 233a of distal end, and then make each point on the first tune 234a with The distance between front end fixed ring 77 gradually increases, to adapt to the profile of user's face.The first profile angle α appropriate can make shading The angle changing of 78 upper end cambered surface of part is adapted with the radian of user's forehead, and then makes light shield device 7 when in use, Ke Yiyu User's face fits closely, and avoids the occurrence of gap, influences the shaded effect of light shield device 7.

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

Since the structure at the pole 233a of distal end is to connect the position of temple, the side of this position and user's face is affixed It closes, therefore, needs to connect subparallel state with central plane 50a holdings equipped with the distal end positions pole 233a, and then make shading piece Position of 78 both sides equipped with distal end pole 233a is relatively parallel, and forms concave structure with front end fixed ring 77, to be fastened on use The face at family, so the first profile angle α has minimum value α 2 at the pole 233a of distal end.In the present embodiment, preferred minimum value α 2 Change between being spent at 12 degree -18.When minimum value α 2 is using 12 degree, the extent of opening of the concave structure of formation is minimum, is suitable for 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, be 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, be 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 the distal end directions pole 233a so that on shading piece 78 Hold the bending degree of the cambered surface formed that continuous variation occurs so that shading piece 78 is equipped with two positions of distal end pole 233a Opposite approach is parallel, so that itself and front end fixed ring 77 form concave structure, to adapt to the radian of user's face profile, ensures to hide 78 upper end of light part is fitted closely with user's face, avoids the occurrence of gap.

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

Specifically, differential of the arc curve 24a forms convergency γ, convergency γ at the pole 233a of distal end with central plane 50a The pole distance L1 between two distal end pole 233a is set to be less than the ring width H1 of front end fixed ring 77.It is worn for the ease of user, Pole distance L1 between two distal end pole 233a, the i.e. opening width of shading piece 78 cannot excessively be less than front end fixed ring 77 Width H1 is avoided because distance L1 is too small, and user can not wear, or, cause shading piece 78 excessive to the clamping force of facial both sides, it is right Skin causes larger pressure, influences the experience of user.

Therefore, in the present embodiment, the pole distance L1 between two distal end pole 233a is limited ring width H1's Between 92.5%-97.5%.Distance L1 is accounted between the 92.5%-97.5% of width H1, can be made equipped with distal end pole 233a When two positions are bonded with user's face side, clamping force appropriate is generated, both will not bring tight feeling to user, it will not be because The little trick of user and easily from face slide.As it can be seen that appropriately distance accounting, may be implemented the patch of light shield device 7 and face There is clamping force appropriate when conjunction, so that light shield device 7 is not generated pressure contact with user's face, constriction is not had, to carry The experience of high user.

Since 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.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, ring width H1 can also change.Under normal conditions, 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, any value between 9.25cm~18.5cm can be used in distance L1； When distance L1 accounts for the 96% of ring width H1, any value between 9.6cm~19.2cm can be used in distance L1；When distance L1 is accounted for Ring width H1 97.5% when, any value between 9.75cm~19.5cm can be used in distance L1.Preferably, distance L1 accounts for ring width H1 95% when to be best apart from accounting, at this point, any value between 9.5cm~19cm can be used in distance L1；And ring width H1 is optimum size between 13cm~15cm, at this point, any between 12.35cm~14.25cm can be used in distance L1 Numerical value.

In addition, in order to make shading piece 78 there is enough length to be bonded with the face of user, needs distal end pole 233a and hide The distance L2 of light part 78 is between the 50%-70% of ring width H1.

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

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

In order to embody the rule of the first profile angle α consecutive variations, so that cambered surface and user plane that 78 upper end of shading piece is formed Contouring is adapted, and when the maximum value α 1 of the first profile angle α 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 maximum value α 1 of the first profile angle α 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 maximum value α 1 of the first profile angle α 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 be continuously enlarged along the direction far from central plane 50a at a distance from front end fixed ring 77.

Second profile angle beta is used to be limited to the bending degree of the variation cambered surface of 78 lower end of shading piece formation so that variation arc The changing rule in face is adapted with the face of user and nose.Since the angle of the second profile angle beta gradually changes so that the The bending degree of two tune 235a is gradually increased from central plane 50a to from the pole 233a of distal end, and then makes two the second tunes 235a can be connected to form domes, and to be bonded with the nose of user, and the rest part of the second tune 235a is curved Qu Chengdu is identical as the radian of user face.Second profile angle beta appropriate can make the bending of the variation cambered surface of 78 lower end of shading piece Degree is adapted with the radian of user's face, and then makes light shield device 7 when in use, can be fitted closely with user's face, Gap is avoided the occurrence of, the shaded effect of light shield device 7 is influenced.

Specifically, since the variation cambered surface that 78 lower end of shading piece 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 value β 1, in the present embodiment, maximum value β 1 changes between being spent at 86 degree -90.When maximum value β 1 is using 90 degree, lower end is formed Variation cambered surface be plane, the user of any is slightly put down suitable for face；When maximum value β 1 is using 86 degree, the variation of lower end formation Cambered surface is arc, and the user of any is slightly roused suitable for face；When maximum value β 1 is using 88 degree, the variation cambered surface that lower end is formed is Arc, suitable for face occupy it is more gentle relatively rouse between user.

Since the structure at the pole 233a of distal end is to connect the position of temple, it is affixed herein with the side of user's face It closes, therefore, needs to connect subparallel state with central plane 50a holdings equipped with the distal end positions pole 233a, and then make shading piece Position of 78 both sides equipped with distal end pole 233a is relatively parallel, and forms concave structure with front end fixed ring 77, to be fastened on use The face at family, so the second profile angle has minimum value β 2 at the pole 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, is 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, and it is more flat to be 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, be suitable for head dummy it is relatively round with compared with User between flat.

Second profile angle beta is continuously reduced from the second minimal point 232a to the distal end directions pole 233a so that under shading piece 78 Hold the variation cambered surface formed in the position being bonded with face, continuous variation occurs for bending degree so that is set on shading piece 78 There is the opposite approach in two positions of distal end pole 233a parallel, so that itself and front end fixed ring 77 form concave structure, to adapt to The radian of user's face profile ensures that 78 lower end of shading piece is fitted closely with user's face, avoids the occurrence of gap.

In order to further illustrate the changing rule of the second profile angle beta, in the present embodiment, the second profile angle beta is limited second Between angle value β 3 at tune 235a distance center plane 50a a quarter ring widthes H1 is spent at 55 degree -65.Second profile angle Between angle value β 4 of the β at second 1/8th ring width H1 of tune 235a distance center planes 50a is spent at 60 degree -75, angle Angle value β 4 is more than angle value β 3；Second profile angle beta is in second 3/8ths ring width H1 of tune 235a distance center planes 50a Between the angle value β 5 at place is spent at 25 degree -31.

In order to embody the rule of the second profile angle beta consecutive variations, so that variation cambered surface and use that 78 lower end of shading piece is formed Family face contour is adapted, and when the maximum value β 1 of the second profile angle beta chooses 86 degree, β 4 chooses 60 degree, and β 3 chooses 55 degree, β 5 25 degree are chosen, minimum value β 2 chooses 10 degree；When the maximum value β 1 of the second profile angle beta chooses 88 degree, β 4 chooses 70 degree, and β 3 is selected 60 degree are taken, β 5 chooses 28 degree, and minimum value β 2 chooses 13 degree；When the maximum value β 1 of the second profile angle beta chooses 90 degree, β 4 chooses 75 Degree, β 3 choose 65 degree, and β 5 chooses 31 degree, and minimum value β 2 chooses 16 degree.

Since light shield device 7 is when being applied on virtual reality device, shading piece 78 will surround frame, to utilize screening Light part 78, the rear shell 3 being connected with frame and the face of user form enclosure space.Therefore, shading piece 78 is solid apart from front end Frame will be surrounded enough by determining the minimum range of ring 77, i.e. the distance is greater than the thickness of frame.In the present embodiment, first is limited Minimal point 231a changes with 78 distance L3 of shading piece between the 5%-15% of ring width H1.

Ring width H1 changes between 10cm~20cm, and when distance L3 accounts for the 5% of ring width H1,0.5cm can be used in distance L3 Any value between~1cm；When distance L3 accounts for the 10% of ring width H1, any between 1cm~2cm can be used in distance L3 Numerical value；When distance L3 accounts for the 15% of ring width H1, any value between 1.5cm~3cm can be used in distance L3.Preferably, away from It is accounting with a distance from best when accounting for the 9.8% of ring width H1 from L3, at this point, appointing between 0.98cm~1.96cm can be used in distance L3 One numerical value；And ring width H1 is optimum size between 13cm~15cm, at this point, distance L3 can be used 1.274cm~ Any value between 1.47cm.
