After display screen, left dust ring, screen support, right dust ring and optical module constitute and accomplish, match through the second fixed orifices that screen fixed orifices 112 on the screen support and virtual reality equipment correspond, realize that the subassembly after the equipment is fixed to virtual reality equipment on, this fixed mode is not restricted to the screw fixation mode. It should be noted that the screen fixing holes 112 of the screen support include at least one forward hole and at least one backward hole.

The following description will be made for each of the above components:

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

The front end fixing ring 77 may be a hollow closed frame, and since the front end fixing ring 77 needs to surround the virtual reality device main body, the shape of the front end fixing ring 77 needs to correspond to the outer shape of the virtual reality device main body. It will be appreciated that if the shape of the virtual reality device body can be rectangular, square or any of a variety of different regular shapes, then the shape of the front end retainer ring 77 will need to be varied accordingly. For example, when the virtual reality apparatus main body selects a form corresponding to the eyeglass form with a certain curvature, the shape of the front end fixing ring 77 is also preferably the eyeglass form, that is, the shape of the front end fixing ring 77 is determined according to the shape of the outer edge of the virtual reality apparatus main body.

Specifically, the light shielding member 78 may be made of a soft material having a certain hardness, being air permeable, and being capable of preventing light from passing therethrough. Preferably, to facilitate the aesthetic appearance of the shade assembly during use, a material that is somewhat resilient and not easily creased, such as a cotton stretcher, lycra, or the like, may be selected. For example, a synthetic cloth having two layers, one for blocking light and the other for ensuring air permeability and being hardly deformed, is selected as the material. Because general cloth is soft, is difficult to form, in order to solve the problem and improve the elasticity, hardness and wear resistance of the synthetic cloth, two layers of cloth are synthesized by glue.

Fig. 24 is a schematic structural diagram of a light shielding assembly of another virtual reality device according to an embodiment of the present disclosure.

Referring to fig. 24, a schematic structural diagram of another virtual reality device shading assembly provided in the embodiment of the present application is different from the foregoing embodiment in that the shading assembly 7 includes: a front end fixing ring 77 and a light shielding member 78. This shading subassembly 7 is cover body structure for with virtual reality equipment fixed mounting. The shading assembly 7 may provide an enclosed space when the user experiences a virtual environment wearing the virtual reality device. Wherein, the front end fixing ring 77 is a closed frame body, is arranged in the outermost side of the shading piece 78, and wraps the virtual reality device body by utilizing the structural cooperation of the front end fixing ring 77 and the front end of the virtual reality device body so as to movably fix the shading component 7 on the virtual reality device.

As shown in fig. 25, one end of the light shielding member 78 is a starting end 21a, the starting end 21a is provided with a connecting opening, one end of the front end fixing ring 77 is provided with a fixing opening, the starting end 21a of the light shielding member 78 is connected with the front end fixing ring 77 through the connecting opening and the fixing opening, the connecting opening and the fixing opening have the same shape and are communicated with each other, so that the formed light shielding assembly 7 has a hollow and stable structure. The light blocking member 78 extends from the start end 21a to the other side connected to the front end fixing ring 77 to form a cut-off end 22a, and the cut-off end 22a has a continuously varying end curve 23 a.

When the virtual reality device is worn, the cut-off end 22a is used for being attached to the face of a user to form a closed space, so that the user can experience a good visual effect. The change rule of terminal curve 23a and user's facial profile looks adaptation to make the user when wearing the virtual reality equipment that has shading subassembly 7, can have better experience and feel, when avoiding anomalous profile and skin contact, cause not equidimension's extrusion, increase user's painful sense, make experience not good. Meanwhile, the regular end curve 23a can be perfectly attached to the face of the user, and no gap is generated. Therefore, the shading component 7 can fully play a shading function, and prevent external light from entering from a gap to influence the visual effect of a user.

In order to make the end curve 23a fit to the face contour of the user, the end curve 23a is required to have a regular change rule. Specifically, the end curve 23a has a first minimum point 231a and a second minimum point 232a on the central plane 50a of the shutter member 7; the first minimum point 231a is located at the top of the shade 78, contacting the center of the user's eyebrow or forehead; the second small spot 232a is located at the bottom end of the shade 78, near the bridge of the user's nose.

The distal-most end of the distal curve 23a on both sides of the central plane 50a has two distal poles 233a, the two distal poles 233a are symmetrical along the central plane 50a, and the distal poles 233a are the distal-most points of the distal curve 23a from the front end fixing ring 77. Distal pole 233a is located where visor 78 is attached to the temple and contacts the side of the user's face, such as near the temple or ear.

As shown in fig. 26, the end curve 23a forms two first curved segments 234a symmetrical along the central plane 50a between the first minimum point 231a and the two distal poles 233 a. The first curved section 234a is located at the upper end of the shade member 78 and has an arc shape extending outward from the center; the connection point of the two first curved sections 234a is the first minimum point 231a, so that the two first curved sections 234a in an arc shape are connected to form a smooth arc surface. The cambered surface is in a state that the center is gentle and the cambered surface is gradually bent to two ends, namely the cambered surface approaches to a plane on two sides of the first minimum point 231a and is gradually bent from the first minimum point 231a to the far end pole point 233a, so that the shape of the cambered surface is matched with the forehead contour of a user. The upper end of the shading part 78 is provided with an arc surface structure matched with the forehead contour of the user, so that the user can comfortably wear the virtual reality equipment with the shading component 7, and the shading part 78 with other structures or irregular structures is prevented from generating oppression on the forehead of the user and influencing the experience of the user. Moreover, if the structure of the light shielding member 78 at the first minimum point 231a is not matched with the forehead contour of the user, a gap is easily generated between the light shielding member 78 and the forehead of the user, which affects the light-tightness of the enclosed space, and further affects the light shielding effect of the light shielding assembly 7.

As shown in fig. 28, the end curve 23a forms two second curved segments 235a symmetrical along the central plane 50a between the second minimum point 232a and the two distal extreme points 233 a. The second curved section 235a is located at the lower end of the shade member 78, where it contacts the face and nose of the user, and has an arc shape extending centrally inward. The connection point of the two second curved sections 235a is the second minimum point 232a, so that the two curved sections 235a are connected to form a smooth changing arc surface. The changing arc surface is in an arch shape at the center and gradually bends to two end points, namely the arc surface is in an arch shape at the second minimum point 232a and is used for adapting to the nose of the user, and the arc surface gradually bends from the second minimum point 232a to the far end maximum point 233a and is used for adapting to the face of the user, so that the whole changing arc surface is in a w shape and is matched with the facial contour of the user. The shape of the changed arc surface is matched with the face and the nose of the user, so that the shading piece 78 is tightly attached to the face contour of the user, a gap is avoided, and the shading effect of the shading component 7 is improved.

As shown in fig. 27, the first curved segment 234a forms a continuously varying first contour angle α with the central plane 50a, and the first contour angle α gradually increases the distance between the first curved segment 234a and the front end fixing ring 77 in a direction away from the central plane 50 a.

The first contour angle α is used to limit the curvature of the arc formed on the upper end of the light-shielding member 78, so that the curvature of the arc is adapted to the forehead contour of the user, the curvature of the first curved section 234a is gradually increased from the central plane 50a to the distal end extreme point 233a due to the gradual change of the first contour angle α, so that the distance between each point on the first curved section 234a and the front end fixing ring 77 is gradually increased to adapt to the contour of the user's face, and the appropriate first contour angle α is used to adapt the curvature of the arc on the upper end of the light-shielding member 78 to the forehead contour of the user, so that the light-shielding member 7 can be tightly attached to the user's face when being used, thereby preventing gaps from affecting the light-shielding effect of the light-shielding member 7.

Specifically, as shown in fig. 29, since the arc formed at the upper end of the light-shielding member 78 is gentle at the first minimum point 231a, the first profile angle α forms a maximum value α 1 at the first minimum point 231a, in the present embodiment, it is preferable that the maximum value α 1 varies from 86 degrees to 90 degrees, when the maximum value α 1 is 90 degrees, the arc formed at the upper end is flat and suitable for a user whose forehead is slightly flat, when the maximum value α 1 is 86 degrees, the arc formed at the upper end is arc and suitable for a user whose forehead is slightly bulged, and when the maximum value α 1 is 88 degrees, the arc formed at the upper end is arc and suitable for a user whose forehead is between flat and flat drums.

The structure at the far end pole 233a is a part for connecting the temple, and the part is attached to the side of the face of the user, so that the part provided with the far end pole 233a needs to be kept approximately parallel to the central plane 50a, and further, the parts at two sides of the shading piece 78 provided with the far end poles 233a are relatively parallel, and form a concave structure with the front end fixing ring 77 so as to be buckled on the face of the user, so that the first contour angle α has a minimum value α 2 at the far end pole 233 a. in the embodiment, the minimum value α 2 is preferably changed between 12 degrees and 18 degrees, when the minimum value α 2 adopts 12 degrees, the formed concave structure has the smallest opening degree and is suitable for users with round head shapes, when the minimum value α 2 adopts 18 degrees, the formed concave structure has the largest opening degree and is suitable for users with flat head shapes, and when the minimum value α 2 adopts 15 degrees, the formed concave structure has moderate opening degree and is suitable for users with flat head shapes between round and flat heads.

The first contour angle α continuously decreases from the first minimum point 231a to the distal end extreme point 233a, so that the curvature of the arc surface formed at the upper end of the light-shielding member 78 continuously changes, and the two parts of the light-shielding member 78, on which the distal end extreme point 233a is disposed, are relatively close to be parallel, so that the two parts and the front end fixing ring 77 form a concave structure to adapt to the curvature of the contour of the user's face, thereby ensuring that the upper end of the light-shielding member 78 is tightly attached to the user's face and avoiding the occurrence of gaps.

As shown in fig. 30, the light shielding member 78 forms a micro-arc curve 24a from the start end 21a to the stop end 22a, which makes the light shielding member 78 exhibit a terminal convergence tendency; the light-shielding member 78 has a convergence trend at the far-end pole 233a, so that the two sides of the light-shielding member 78 can clamp the two sides of the user's face, thereby increasing the fit tightness between the light-shielding assembly 7 and the user's face, avoiding the damage to the originally tightly-attached structure due to the shaking of the user's head, and avoiding the generation of gaps.

Specifically, the micro-arc curve 24a forms a convergence angle γ with the central plane 50a at the distal poles 233a, the convergence angle γ being such that the pole distance L1 between the two distal poles 233a is smaller than the ring width H1 of the front end fixing ring 77. In order to facilitate wearing, the pole distance L1 between the two distal poles 233a, that is, the opening width of the light shielding piece 78 cannot be too smaller than the width H1 of the front end fixing ring 77, so as to avoid that the user cannot wear the light shielding piece 78 due to too small distance L1, or that the clamping force of the light shielding piece 78 on the two sides of the face is too large, so that the user's experience is affected by large pressure on the skin.

Thus, in the present embodiment, the pole distance L1 between the two distal poles 233a is defined to be between 92.5% and 97.5% of the ring width H1. The distance L1 occupies 92.5% -97.5% of the width H1, so that when the two parts provided with the distal ends 233a are attached to the sides of the user's face, a proper clamping force is generated, which does not give a tight feeling to the user or easily slide from the face due to small movements of the user. Therefore, the proper distance is used for comparison, and the proper clamping force can be realized when the shading component 7 is attached to the face, so that the shading component 7 is not in pressure contact with the face of a user and is not in pressure feeling, and the user experience is improved.

Since the ring width H1 is adapted to the face width of the user, in the present embodiment, the ring width H1 is defined in terms of the face width of the user. The loop width H1 also varies because the face width varies from user to user due to the difference in head shape of each user or the difference in age of the user. Typically, adult faces are between about 13cm and 20cm wide, while minor faces are between about 10cm and 15cm wide, and as can be seen, the most common face widths are between 13cm and 15 cm. I.e. the ring width H1 varies between 10cm and 20cm, preferably the ring width H1 is optimally between 13cm and 15 cm.

When the distance L1 accounts for 92.5% of the ring width H1, the distance L1 can adopt any value between 9.25cm and 18.5 cm; when the distance L1 accounts for 96% of the ring width H1, the distance L1 can adopt any value between 9.6cm and 19.2 cm; when the distance L1 is 97.5% of the ring width H1, the distance L1 may take any value between 9.75cm and 19.5 cm. Preferably, the distance L1 is the optimal distance ratio when the distance L1 accounts for 95% of the ring width H1, and in this case, the distance L1 can adopt any value between 9.5cm and 19 cm; while the ring width H1 is preferably between 13cm and 15cm, the distance L1 may be any value between 12.35cm and 14.25 cm.

In addition, in order to have a sufficient length of the light shield 78 to fit the user's face, the distance L2 between the distal pole 233a and the light shield 78 is between 50% and 70% of the ring width H1.

When the distance L2 accounts for 50% of the ring width H1, the distance L2 can adopt any value between 5cm and 10 cm; when the distance L2 accounts for 60% of the ring width H1, the distance L2 can adopt any value between 6cm and 12 cm; when the distance L2 is 70% of the ring width H1, the distance L2 may take any value between 7cm and 14 cm. Preferably, the optimal distance ratio is obtained when the distance L2 accounts for 57.5% of the ring width H1, and in this case, the distance L2 can take any value between 5.75cm and 11.5 cm; while the ring width H1 is preferably between 13cm and 15cm, the distance L2 may be any value between 7.475cm and 8.625 cm.

To further illustrate the variation of the first profile angle α, in the present embodiment, the first profile angle α is defined to have an angle value α 3 of between 52 degrees and 58 degrees at a quarter loop width H1 of the first curved segment 234a from the central plane 50a, an angle value α 4 of the first profile angle α at an eighth loop width H1 of the first curved segment 234a from the central plane 50a is between 75 degrees and 80 degrees, and an angle value α 5 of the first profile angle α at an eighth loop width H1 of the first curved segment 234a from the central plane 50a is between 29 degrees and 35 degrees.

In order to embody the rule that the first contour angle α changes continuously, so that the arc surface formed at the upper end of the light shielding member 78 is matched with the contour of the face of a user, when the maximum value α 01 of the first contour angle α is 86 degrees, the α 14 is 75 degrees, the α 23 is 52 degrees, the α 35 is 29 degrees, the minimum value α 42 is 12 degrees, when the maximum value α 61 of the first contour angle α 5 is 88 degrees, the α 74 is 78 degrees, the α 83 is 55 degrees, the α 5 is 32 degrees, the minimum value α 2 is 15 degrees, when the maximum value α 1 of the first contour angle α is 90 degrees, the α 4 is 80 degrees, the α 3 is 58 degrees, the α 5 is 35 degrees, and the minimum value α 2 is 18 degrees.

As shown in fig. 31, the second curved segment 235a forms a continuously varying second contour angle β with the central plane 50a, and the second contour angle β continuously increases the distance between the second curved segment 235a and the front end fixing ring 77 in a direction away from the central plane 50 a.

The second contour angle β is used to limit the curvature of the variable arc formed at the lower end of the shade 78, so that the variation rule of the variable arc is adapted to the face and nose of the user, since the angle of the second contour angle β is gradually changed, the curvature of the second curved segment 235a is gradually increased from the central plane 50a to the distal end pole 233a, so that the two second curved segments 235a can be connected to form an arch structure to fit the nose of the user, and the curvature of the rest of the second curved segment 235a is the same as the curvature of the face of the user, and the appropriate second contour angle β can adapt the curvature of the variable arc at the lower end of the shade 78 to the curvature of the face of the user, so that the shade 7 can closely fit the face of the user when being used, thereby preventing the occurrence of gaps and affecting the shade effect of the shade 7.

Specifically, the variable arc formed at the lower end of the shade member 78 forms an arch at the second minimum point 232a, and the portion connected to the arch is used for fitting the face, so the second contour angle β has a maximum value β 1 at the second minimum point 232a, in this embodiment, the maximum value β 1 varies from 86 degrees to 90 degrees, when the maximum value β 1 adopts 90 degrees, the variable arc formed at the lower end is a plane and is suitable for a user with a slightly flat face, when the maximum value β 1 adopts 86 degrees, the variable arc formed at the lower end is an arc and is suitable for a user with a slightly bulging face, and when the maximum value β 1 adopts 88 degrees, the variable arc formed at the lower end is an arc and is suitable for a user with a face between a relatively flat and a relatively flat drum.

Since the structure at the distal pole 233a is a portion for connecting the temple, and is attached to the side of the user's face, the portion provided with the distal pole 233a needs to be kept approximately parallel to the central plane 50a, and further, the portions of the light-shielding member 78 at both sides provided with the distal poles 233a are relatively parallel, and form a concave structure with the front end fixing ring 77 to be fastened to the user's face, so that the second contour angle has a minimum value β 2 at the distal pole 233a, and in this embodiment, the minimum value β 2 preferably varies from 10 degrees to 16 degrees, and when the minimum value β 2 is 10 degrees, the formed concave structure has the smallest opening degree and is suitable for users with round heads, when the minimum value β 2 is 16 degrees, the formed concave structure has the largest opening degree and is suitable for users with flat heads, and when the minimum value β 2 is 13 degrees, the formed concave structure has the moderate opening degree and is suitable for users with flat heads between round and flat heads.

The second contour angle β continuously decreases from the second minimum point 232a to the far-end extreme point 233a, so that the curvature of the variable arc surface formed at the lower end of the light-shielding member 78 continuously changes, and the two parts of the light-shielding member 78 provided with the far-end extreme point 233a are relatively close to be parallel, so that the two parts and the front end fixing ring 77 form a concave structure to adapt to the radian of the user's facial contour, thereby ensuring that the lower end of the light-shielding member 78 is tightly attached to the user's face and avoiding the occurrence of gaps.

To further illustrate the variation of the second profile angle β, in this embodiment, the second profile angle β is defined to have an angle value β 3 of between 55 degrees and 65 degrees at a quarter loop width H1 of the second curved segment 235a from the center plane 50a, an angle value β 4 of the second profile angle β at an eighth loop width H1 of the second curved segment 235a from the center plane 50a is between 60 degrees and 75 degrees, an angle value β 4 is greater than an angle value β 3, and an angle value β 5 of the first profile angle β at an eighth loop width H1 of the first curved segment 235a from the center plane 50a is between 25 degrees and 31 degrees.

In order to embody the rule that the second contour angle β changes continuously, so that the change arc surface formed at the lower end of the light shielding member 78 is matched with the contour of the face of the user, when the maximum value β 01 of the second contour angle β is 86 degrees, the β 14 is 60 degrees, the β 23 is 55 degrees, the β 35 is 25 degrees, and the minimum value β 42 is 10 degrees, when the maximum value β 61 of the second contour angle β 5 is 88 degrees, the β 74 is 70 degrees, the β 83 is 60 degrees, the β 5 is 28 degrees, the minimum value β 2 is 13 degrees, when the maximum value β 1 of the second contour angle β is 90 degrees, the β 4 is 75 degrees, the β 3 is 65 degrees, the β 5 is 31 degrees, and the minimum value β 2 is 16 degrees.

Since the shade assembly 7 is applied to the virtual reality device, the shade member 78 surrounds the frame to form a closed space using the shade member 78, the rear case 3 coupled to the frame, and the face of the user. Therefore, the minimum distance of the light blocking member 78 from the front end fixing ring 77 is sufficient to surround the lens frame, i.e., the distance is greater than the thickness of the lens frame. In the present embodiment, the distance L3 defining the first minimum point 231a from the light-shielding member 78 varies between 5% and 15% of the ring width H1.

The ring width H1 is changed between 10cm and 20cm, and when the distance L3 accounts for 5 percent of the ring width H1, the distance L3 can adopt any value between 0.5cm and 1 cm; when the distance L3 accounts for 10% of the ring width H1, the distance L3 can adopt any value between 1cm and 2 cm; when the distance L3 is 15% of the ring width H1, the distance L3 may take any value between 1.5cm and 3 cm. Preferably, the distance L3 is the optimal distance ratio when the distance L3 accounts for 9.8% of the ring width H1, and in this case, the distance L3 can adopt any value between 0.98cm and 1.96 cm; while the ring width H1 is most suitably between 13cm and 15cm, the distance L3 may take any value between 1.274cm and 1.47 cm.

When the virtual reality device with the shading component 7 is worn, the nose support of the virtual reality device is in contact with the nose of a user, and the nose support is arranged at the lower end of the glasses frame. Therefore, the arch formed at the lower end of the shade 78 need only fit the structure of the nose pad, rather than completely wrapping the nose pad, to prevent the lower end of the shade 78 from contacting the nose of the user. It can be seen that the lower end of the light-shielding member 78 can be completely connected to the front end fixing ring 77 without leaving a width, or the width of the lower end of the light-shielding member 78 does not exceed the thickness of the frame, and the width of the lower end of the light-shielding member 78 is the distance L4 between the second minimum point 232a and the light-shielding member 78. In this embodiment, the distance L4 between the second minimum point 232a and the light-shielding member 78 is defined to be between 0% and 15% of the ring width H1.

When distance L4 accounts for 0% of ring width H1, distance L4 is also 0 cm; when the distance L4 accounts for 10% of the ring width H1, the distance L4 can adopt any value between 1cm and 2 cm; when the distance L4 is 15% of the ring width H1, the distance L4 may take any value between 1.5cm and 3 cm. Preferably, the distance L4 is the optimal distance ratio when the distance L4 accounts for 7.5% of the ring width H1, and in this case, the distance L4 can adopt any value between 0.75cm and 1.5 cm; while the ring width H1 is most suitably between 13cm and 15cm, the distance L4 may take any value between 0.975cm and 1.125 cm.

In order to install the light shielding assembly on the virtual reality device, a closed space is formed by the upper end of the light shielding piece 78, the nose support on the glasses frame and the face of the user, the width of the upper end of the light shielding piece 78 is required to be larger than that of the lower end, namely the distance L4 is smaller than the distance L3, the lower end of the light shielding piece 78 is prevented from contacting with the face of the user, and the user experience is reduced.

In order to form the arch structure after the two second curved sections 235a having the arc shape are connected to match the shape of the nose pad, the two second curved sections 235a are bent upward after contacting the front end fixing ring 77. And in order to accommodate the width of the nose pad, it is necessary to define a distance between two intersection points where the two second curved sections 235a are connected to the front end fixing ring 77, i.e., a distance between the two intersection points is close to the width of the nose pad.

Specifically, the two second curved segments 235a intersect the front end fixed ring 77, respectively, to form two intersection points a symmetrical along the central plane 50a, and a distance L5 between the two intersection points a is not more than one fourth of the ring width H1; because the ring width H1 varies between 10cm and 20cm, when the ring width H1 is 10cm, the distance L5 can adopt any value within the range of less than 2.5 cm; when the ring width H1 is 15cm, the distance L5 can take any value within the range of less than 3.75 cm; when 20cm is used for the ring width H1, the distance L5 may take any value within a range of less than 5 cm. Preferably, when the ring width H1 is 14cm, which is the optimum width, the distance L5 may take any value within a range of less than 3.5 cm.

Since one end of the second curved segment 235a is connected to the front end fixing ring 77, the distance between the section of the end curved line 23a between the intersection points a and the front end fixing ring 77 is always 0.

In order to make the light-shielding assembly 7 provided by the present application generate a better comfort when being attached to the face of the user, in the present embodiment, the light-shielding member 78 may be made of a soft material that has a certain hardness, is air-permeable, and can prevent light from passing through. Preferably, to facilitate the aesthetic appearance of the shade assembly 7 during use, a material may be selected that has some elasticity and is not prone to wrinkling, such as, for example, lapel cotton, lycra, and the like. For example, the material is a synthetic cloth having two sides, one side for blocking light and the other layer for ensuring air permeability and being not easily deformed. Because general cloth is soft, is difficult to form, in order to solve the problem and improve the elasticity, hardness and wear resistance of the synthetic cloth, two layers of cloth are synthesized by glue. This application is through the 7 outlines of shading subassembly of design laminating face facial curve to utilize the soft characteristic of soft cloth, realize shading subassembly 7 and the facial laminating of user, improve user's experience.

For example, a protrusion with a size close to the positioning notch 236a may be provided on the contact surface between the front end fixing ring 77 and the light shielding member 78, and when the light shielding member 78 is fixed to the front end fixing ring 77, the positioning notch 236a is fixed to the protrusion of the front end fixing ring 77, so as to determine the relative position between the light shielding member 78 and the front end fixing ring 77. Further, in an alternative embodiment, as shown in fig. 32, the second small dots 232a are located at both ends of the light blocking member 78 after the planar expansion, i.e., the cut edges of the light blocking member 78, and when the light blocking member 78 is mounted on the front end fixing ring 77, the light blocking member 78 is butt-spliced at the second small dots 232 a. Since the width of the light blocking member 78 at the second pole-point 232a is minimized, locating the cut edge of the light blocking member 78 at the second pole-point 232a minimizes the impact of the splice on the overall structure and appearance of the light blocking member 78.
