(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 drawing, and preferably, the number of the inclined grooves 213 is 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.

Further, the present application provides a face support 6, which is a kind of accessory of a virtual reality device, including a face contact portion 63 and a body fixing portion 64 fixed together. In the actual wearing process, the face contact part 63 is mounted at the middle position of the rear case 3 of the virtual reality device through the body fixing part 64. In order to increase the wearing comfort, the face contact portion 63 is made of a softer material such as sponge, foam, or the like; in order to facilitate the installation of the face support 6 on the virtual reality device and increase the stability of the installed face support 6, the main body fixing portion 64 may be made of a material having certain elasticity and hardness, such as plastic, light metal, etc. The face contacting portion 63 and the body fixing portion 64 are fixed by means of a fixing means such as gluing, detachable connection without mutual sliding, etc., which satisfies stability requirements.

As shown in fig. 24, the present invention provides the face support 6 in which the face contact portion 63 and the body fixing portion 64 are formed in a zigzag configuration by a flange 602 located at a center line 601 and two arc portions 603 symmetrical to the center line 601. Wherein the face contacting portion 63 includes a side contacting section 604 and a middle contacting section 605 extending from the flange 602 to the side contacting section 604. It should be noted that the center line 601 is located at a middle position of the flange 602, and the entire face contacting portion 63 and the body fixing portion 64 are defined as two portions symmetrical with respect to the center line 601, wherein each portion includes an arc portion 603. The arc 603 is further divided into a middle contact section 605 and a side contact section 604 in the direction away from the flange 602, and it is obvious that, in the above features, the center line 601, the flange 602, the middle contact section 605 and the side contact section 604 are names indicating orientation features indicating the positions and ranges of the face contact portion 63 and the body fixing portion 64. The corresponding positions in the entity can be represented by the above-described features in both the face contact portion 63 and the body fixing portion 64.

The face-contacting portion 63 includes an inner edge 631 and an outer edge 632, and an attachment side 633 and an attachment side 634 that extend from the inner edge 631 to the outer edge 632. The inner edge 631 of the face-contacting portion 63 refers to the position of the inner edge of the zigzag structure of the face-contacting portion 63 that contacts the wearer's face during wearing; the outer edge 632 of the face contact portion 63 is the outer edge of the zigzag structure that fits the optical module in the virtual reality device. By the above setting of the two edge positions, the entire face contact portion 63 can be divided into the attaching side 633 corresponding to the face of the wearer and the connecting side 634 attached to the main body fixing portion 64.

Referring to fig. 24, the points on the laminating side 633 where the thickness L is at its maximum form a continuous laminating curve 635. The entire fit curve 635 varies as the shape of the face contact portion 63 varies. The fit curve 635 forms a raised convex configuration throughout the face-contacting portion 63, and forms a fit face 636 and an outer edge support face 637 on either side of the fit curve 635. The attachment surface 636 is a smooth curved surface continuously extending from one side of the attachment curve 635 close to the inner edge 631, and the curved surface change rule of the attachment surface 636 is in accordance with the facial structure of the human body, so that the attachment surfaces 636 at the two middle contact sections 605 are attached to the two sides of the nose of the wearer; the binding surfaces 636 positioned at the two side contact sections 604 are bound with the two sides of the face of the wearer, so that the contact surface with the user can be increased, the load bearing of a unit area is reduced, and the long-time wearing of the user is facilitated, so that the experience of the user is improved; but also can make users with different nose shapes and face shapes well fit.

The outer edge support surface 637 is a curved surface located on one side of the fitting curve 635 close to the outer edge 632, and the outer edge support surface 637 is fitted to an optical module of the virtual reality device. In order to adjust the imaging distance, for wearers with different vision conditions, the virtual reality device is often provided with an optical module between the screen and the eyes. The general optical module includes a lens barrel and a lens disposed inside the lens barrel, and the optical module protrudes out of the rear housing 3 of the virtual reality device due to the adjustment distance required. In the technical scheme provided by the application, the outer edge support face 637 is attached to the outer wall of the lens barrel of the optical module protruding rear shell 3, so that the adjustment of the optical module is not influenced, and the influence on the viewing effect caused by the light leakage due to the gap formed between the outer edge support face 637 and the rear shell 3 is avoided.

For the connecting side 634 opposite to the attaching side 633, as shown in fig. 25, the connecting side 634 is provided with a connecting groove 638, and the groove bottom 6381 of the connecting groove 638 is provided with a connecting surface 6382 near the inner edge 631; the rim support surface 637 is connected to the groove bottom 6381. The slot bottom 6381 is parallel to the back shell 3 of the virtual reality device when in the mounted position, i.e. the slot bottom 6381 remains parallel to the display screen, the front shell 2 and the back shell 3 during wearing. When the virtual reality device is in a zero position, the slot floor 6381 is in a vertical state.

The slot floor 6381 extends from the flange 602 to the two side contact segments 604 along the conforming curve 635. The connection surface 6382 is a curved surface that is inclined with respect to the groove bottom surface 6381, and the connection surface 6382 continuously changes according to the change in the outer shape of the entire surface contact portion 63. The connecting surface 6382 forms a convex curved surface relative to the slot bottom surface 6381 on the connecting side 634, and the attaching surface 636 is a curved surface that is concave toward the connecting side 634 relative to the attaching curve 635 on the attaching side 633, so that the distance between the attaching surface 636 and the connecting surface 6382 can be reduced, the weight of the whole face contact part 63 is further reduced, and the whole virtual reality device is lighter and thinner. Also can let face hold in the palm 6 and the facial abundant laminating, increase area of contact so that fixed, can also be in the holding capacity, the effect of even transmission power weakens and avoids face to hold in the palm 6 damages increase of service life. Of course, the full fit can also block the entrance of outside light.

The rim support surface 637 is connected to the groove bottom 6381; the included angle formed in a direction adjacent to the inner edge 631 is a right angle or an acute angle. The included angle formed in the direction near the inner edge 631 is a right or acute angle, i.e., the outer edge support surface 637 is perpendicular to the groove bottom 6381, or the outer edge support surface 637 is inclined toward the inner edge 631 at the attachment side 633. The above structure can be adapted to lens barrels of most optical assemblies. For example, when the lens barrel is cylindrical, the corresponding outer edge support surface 637 is perpendicular to the groove bottom 6381, so that the outer wall of the lens barrel in the optical assembly can be sufficiently attached, and a gap formed between the lens barrel and the outer edge support surface 637 is reduced, thereby preventing light from entering at the attachment part of the face support 6 and the lens barrel.

When the included angle formed between the outer edge supporting surface 637 and the groove bottom 6381 in the direction close to the inner edge 631 is an acute angle, the outer edge supporting surface 637 is inclined outward relative to the lens barrel of the optical assembly in the direction from the connecting side 634 to the attaching side 633, so that the outer edge supporting surface 637 is gradually away from the outer wall of the lens barrel, thereby avoiding the deformation of the soft material caused by compression when the face contact portion 63 is worn, blocking the lens of the optical assembly, and reducing the influence on the viewing effect. It should be noted that, in order to better ensure the shading effect, the outer edge support surface 637 is not inclined at an excessively large angle. Because too big inclination can lead to outer fringe supporting surface 637 in the position of pressing close to the people's face, and form great gap with the lens cone outer wall between, very easily lead to outside light to get into from the gap, influence and look shadow effect.

In some embodiments of the present application, a light blocking portion 68 is also provided on the outer edge support surface 637, near the slot bottom 6381, extending from the middle contact section 605 to the end 606 of the side contact section 604. Because the virtual reality equipment needs to be additionally provided with the light shield in the wearing process, and in order to adapt to the facial structure, the light shield is smaller at the middle position of the whole virtual reality equipment, so that light can easily enter a visual field space at the middle position, the light shield part 68 extends from the middle contact section 605 to the tail end 606 of the side contact section 604, gaps can be reduced at the middle position, and the light leakage phenomenon is avoided. At the end 606 of the side contact section 604, on one hand, the outer edge supporting surface 637 of the face support 6 no longer contacts the outer wall of the lens barrel, and on the other hand, at the position corresponding to the end 606, the area of the light shield tends to be large, and the light leakage phenomenon is not easy to occur, so in this embodiment, the light shield portion 68 extends from the middle contact section 605 to the end 606 of the side contact section 604, which can reduce the gap generation at the middle contact section 605, and can also avoid unnecessary structure increase process difficulty at the side contact section 604.

Further, the light shielding portion 68 has a step-like structure, as shown in fig. 26, and includes a first light shielding surface 681 parallel to the groove bottom surface 6381, and a second light shielding surface 682 connecting the groove bottom surface 6381 and the first light shielding surface 681, where the second light shielding surface 682 is perpendicular to the first light shielding surface 681. In the embodiment of the present application, the light shielding portion 68 is composed of two curved surfaces, namely a first light shielding surface 681 and a second light shielding surface 682, which conform to the shape of the outer edge 632, wherein the first light shielding surface 681 is parallel to the groove bottom surface 6381 and is used for attaching to the end surface of the optical component barrel; the second light shielding surface 682 is perpendicular to the first light shielding surface 681, and is used for attaching to an outer circumferential wall of the optical component barrel. The light shielding portion 68 of the stepped structure covers the optical component portion protruding from the rear housing in the outer edge support surface 637, and the stepped structure is the same as the lens barrel structure, so that the gap between the lens barrel and the face support 6 can be tightly closed by the first light shielding surface 681. In addition, the stepped structure can seal the gap and prevent the face contact part 63 made of soft material from deforming due to the extrusion of the lens barrel and the face contact part 63, thereby influencing the attaching and shading effects at the contact position.

The face support accessory further comprises a main body fixing part 64 used for fixing the face contact part 63 on the virtual reality device rear shell 3. The body fixing portion 64 is formed to conform to the shape of the groove bottom 6381 and the connecting surface 6382 in order to fit the surface contact portion 63. This allows the body fixing portion 64 to be in full contact with the face contacting portion 63, increasing the firmness and enhancing the uniformity of the force transmission. In actual use, the face contact part 63 and the body fixing part 64 are fixed together by gluing or detachable fixing, and the face contact part 63 is mounted on the virtual reality device through the body fixing part 64.

In one embodiment, the light blocking portion 68 on the face support 6 assembly transitions from the middle contact portion 605 to the end 606 of the side contact portion 604, and the width W1 of the first light blocking surface 681 is constant; the width W2 of the second light-shielding facet 682 is constant from the middle contact segment 605 to the end 606 of the side contact segment 604. Here, the widths W1 and W2 are constant values, and indicate that the widths of the first light shielding surface 681 and the second light shielding surface 682 are constant in physical structure, that is, the stepped structure is the same in any cross section. Because the backshell 3 of virtual reality equipment is generally the plane for optical component goes up the bellied height on backshell 3 and maintains invariable relatively, therefore in this embodiment, the width of first shading face 681 and second shading face 682 maintains invariable correspondingly, can make first shading face 681 fully laminate with optical component's lens-barrel terminal surface, and second shading face 682 fully laminates with optical component's lens-barrel outer wall, avoids producing the gap at the laminating position, reduces outside light and gets into field of vision scope, influences and sees the shadow and experiences.

It should be noted that in this embodiment, the widths of the first shading surface 681 and the second shading surface 682 are kept constant, not completely constant, and the width of the first shading surface 681 is gradually increased from the outside to the inside until the proper width is kept constant and then gradually decreased from the outside to the end 606 position by extending the outer edge 632 in order to form a transition part between the middle contact section 605 near the flange 602 and the end 606 position of the side contact section 604 and the contour of the outer edge 632 of the face contact portion 63. The structure can generate smooth transition at the position where the edges are contacted, and the lens barrel is prevented from being extruded at the two positions to influence the shading effect.

In some embodiments of the present application, the width W1 of the first light shading surface 681 is less than or equal to 1/2 of the width of the slot bottom 6381. When the face support 6 is mounted on the virtual reality device, the groove bottom surface 6381 of the face support 6 is connected to the rear case 3 of the virtual reality device through the body fixing portion 64, and after the mounting is completed, the groove bottom surface 6381 is kept parallel to the rear case 3. In the middle contact section 605, the width of the groove bottom surface 6381 is the bonding width between the face support 6 and the rear case 3 in the middle contact section 605, and the groove bottom surface 6381 of the face support 6 cannot be too small for the stability of bonding, but the light shielding portion 68 occupies the width of the groove bottom surface 6381, thereby affecting the stability of bonding. Therefore, in this embodiment, the width W1 of the first light shielding surface 681 is less than or equal to the width 1/2 of the groove bottom 6381, so that the attachment to the end surface of the lens barrel can be ensured and the stability of the contact of the face support 6 on the rear case 3 can be ensured.

In addition, due to the wall thickness limitation of the lens barrel, the width W1 of the first light shielding surface 681 should not be too large, because the first light shielding surface 681 is fitted to the end surface of the lens barrel in the optical assembly when the face support 6 is mounted on the rear case 3 of the virtual reality device. For a general optical assembly, the end face is used for observation, which also prevents the first light shielding face 681 from shielding the lens or the observation area in the optical assembly, so that the width W1 of the first light shielding face 681 is set to be less than or equal to 1/2 of the width of the slot bottom 6381, and the first light shielding face 681 can be prevented from affecting the film viewing process.

Further, the width W2 of the second light-shielding surface 682 is smaller than or equal to the thickness L of the face contact portion 63. In this embodiment, the second light shielding surface 682 is attached to the outer wall of the barrel of the optical unit, and the width W2 is sufficient to allow the first light shielding surface 681 to be attached to the barrel end surface of the optical unit. Moreover, since the face contact portion 63 is made of a soft material, if the width W2 of the second light-shielding surface 682 is too large, the face contact portion 63 may be deformed due to the pressure applied by the face when the soft material is close to the optical component, which may affect the stability of the attachment and may cause a gap.

The face support 6 further includes a limit projection 65 on the inner edge 631 of the flange 602 of the face contacting portion 63, the connecting sides 634 of the middle contacting section 605 and the side contacting section 604, and the outer edge 632 of the connecting side 634 of the flange 602. Because the face contact part 63 is made of soft material and the body fixing part 64 is made of hard material, the limit bosses 65 arranged on the inner edge 631 and the outer edge 632 can generate a coating effect on the body fixing part 64 with the edge position of the body fixing part 64 in actual use, and the phenomena of gaps and light leakage caused by insufficient adhesion between hard materials when the body fixing part 64 is installed on the rear shell 3 of the virtual reality device are avoided.

In addition, a limit projection 65 is protrudingly provided on the inner edge 631 and a part of the outer edge 632. The height of the protrusion of the position-restricting projection 65 is kept consistent with the thickness of the body fixing portion 64. That is, after the face contact portion 63 and the body fixing portion 64 are fixed together, the tip end of the stopper boss 65 is flush with the edge of the rear case side 641 of the body fixing portion 64. This structure can reduce the possibility that the face contact portion 63 is easily peeled off from the body fixing portion 64 during long-time wearing by absorbing the deformation of the face contact portion 63 caused by the pressure.

Further, as shown in fig. 27 and 28, in the face support 6 provided in this embodiment, the limiting boss 65 at the position of the outer edge 632 of the flange 602 is close to the side surface of the outer edge 632, and the included angle γ 1 between the tangent lines of the second light-shielding surface 682 at the contact position is less than or equal to 180 degrees; the side surface of the limiting boss 65 near the outer edge 632 at the end 606 of the side contact section 604 forms an included angle γ 2 with the tangent of the second light-shielding surface 682 at the end 606, which is less than or equal to 180 degrees. Such a structure can increase the bonding area of the edge position where the lens barrel is bonded to the light shielding portion 68, and prevent light leakage at this position.

In some embodiments of the present application, the main body fixing portion 64 includes a back shell side 641, and a face support side 642 attached to the connecting side 634; in order to be fixed to the face contact portion 63 and increase the overall stability, in the present embodiment, the face support side 642 is provided with a stopper surface 643 which is attached to the groove bottom surface 6381 and has the same shape as the groove bottom surface 6381, and a fixing surface 644 which is attached to the connecting surface 6382.

In actual use, since the face contact portion 63 is made of a soft material and the body fixing portion 64 is made of a hard material, when the two are fixedly connected, there is a possibility that the entire face contact portion 63 is deviated from a predetermined position due to deformation of the soft material, thereby affecting the stability of the entire face support 6. Therefore, in order to increase the stability of the entire structure, in the present embodiment, the stopper surface 643 conforming to the shape of the groove bottom surface 6381 and the fixing surface 644 conforming to the shape of the connection surface 6382 are provided on the face receiving side 642 of the body fixing portion 64, respectively, and the face contact portion 63 is stably restricted to the body fixing portion 64 by the restriction of the entire shape.

According to the body fixing portion 64 described in the above embodiments, in some embodiments of the present application, as shown in fig. 30 and 31, the back case side 641 includes a back case abutting surface 6411 and a transition surface 6412 connecting the back case abutting surface 6411. The back shell attachment surface 641 is attached to the back shell 3 of the virtual reality device in the actual fixing process. Specifically, the fastening manner such as an adhesive fastening manner or a detachable fastening manner may be selected, and optionally, the detachable fastening manner is selected, specifically, for example, the rear housing attaching surface 6411 and the transition surface 6412 are respectively provided with at least two locking members 60 that are symmetrical with respect to the center line 601. In this embodiment, as shown in fig. 32, the locking member 60 disposed on the back shell facing surface 6411 and the transition surface 6412 can be detachably connected to the main body fixing portion 64 through the locking member 60, so that the same virtual reality device can be changed to the face support 6 according to different users. In the specific use process, the back shell binding face 6411 is bound with the virtual reality equipment, and the transition face 6412 is bound with the inclined face at the bottom of the virtual reality equipment. Therefore, when the user wears the virtual reality equipment, the virtual reality equipment is in surface contact with the main body fixing part 64, the force is transmitted more uniformly, and the main body fixing part 64 and the virtual reality equipment can be stably connected.

To further engage the light blocking portion 68, the side of the stop surface 643 near the outer edge 632 is flush with the second light blocking surface 682 in the region where the transition from the middle contact section 605 to the tip 606 occurs. The above structure can not only fit the lens barrel of the optical assembly of the second light shielding face 682 to pass through the joint part, but also can use the hard material of the main body fixing part 64 to assist in fixing the light shielding part 68, and prevent the face contact part 63 made of soft material from being extruded and deformed by the optical assembly.

In one embodiment, as shown in fig. 29, the contact surface 636 is inclined with respect to the groove bottom surface 6381, the contact surface 636 gradually approaches the groove bottom surface 6381 in the direction of the inner edge 631 side, the inner inclination angle α formed by the contact surface 636 and the groove bottom surface 6381 continuously changes over the entire face contact portion 63, the contact surface 6382 is inclined with respect to the groove bottom surface 6381, the contact surface 6382 gradually moves away from the groove bottom surface 6381 in the direction of the inner edge 631 side, and the outer inclination angle β formed by the contact surface 636 and the groove bottom surface 6381 continuously changes over the entire face contact portion 63.

The abutting surface 636 and the connecting surface 6382 are both inclined with respect to the groove bottom 6381, but the inclination of the abutting surface 636 is inclined from the abutting curve 635 toward the connecting side 634 to form a curved surface gradually decreasing with respect to the abutting curve 635 to the inner edge 631; the connection surface 6382 is inclined from the groove bottom 6381 in the direction of the connection side 634 to form a curved surface gradually rising with respect to the groove bottom 6381 up to the position of the inner edge 631.

With respect to the inner inclination angle α between the abutment surface 636 and the groove bottom surface 6381, in the present embodiment, the inner inclination angle α is defined as the angle between the groove bottom surface 6381 and a straight line on the abutment surface 636 perpendicular to the tangential direction of any point on the abutment curve 635 and defined toward the inner edge 631, and the inner inclination angle α gradually increases and then gradually decreases during the transition from the flange 602 to the middle contact section 605 and then to the side contact sections.

Similarly, the camber angle β between the connection surface 6382 and the slot bottom 6381 is defined as the angle between the straight line drawn from the edge of the slot bottom 6381 perpendicular to the tangent line of any point of the inner edge 631 on the connection surface 6382 and the slot bottom 6381, which is the same as the change rule of the camber angle α. in some embodiments of the present application, the camber angle α is equal to the camber angle β in any tangent plane perpendicular to the slot bottom 6381 and perpendicular to the tangent line of the attachment curve 635. in some embodiments, two intersecting lines formed between the attachment surface 636 and the connection surface 6382 are parallel to each other, so as to form a uniform-quality face contact 63, so that the pressure applied to each point on the attachment surface 636 is relatively uniform, thereby avoiding the contact surface with the user being less, causing the contact point to be subjected to a relatively large force, further causing the user to wear for a long time and even causing the damage to the contact portion, and enlarging the contact surface, thereby ensuring that the face contact portion 63 can be stably fixed on the wearer.

On the flange 602 of the face contact portion 63, both the inclination angles α and β are continuously changed, the inclination angles α and β are minimum at the position of the center line 601 of the flange 602, and the inclination angles α and β are gradually increased in the direction away from the center line 601 toward the middle contact portion 605. this structure can adapt to the bridge structure of the wearer between the two eyes, and because the flange 602 of the face contact portion 63 needs to cross the top position of the bridge of the nose of the wearer and the top position of the bridge of the nose protrudes less relative to the face, the inclination angles α and β at the position of the center line 601 are minimum, so as to adapt to the face structure of the user, so that the display of the virtual reality device is just in front of the glasses of the user, and the situation that the user cannot bring the virtual reality device on the glasses or the contact area is too small is avoided.

The inclination angles α and β gradually increase and then gradually decrease in the middle contact section 605 of the face contacting portion 63. in this embodiment, the middle contact section 605 of the face contacting portion 63 is configured to engage the sides of the bridge of the nose of the wearer. for most wearers, the width of the bridge of the nose increases from top to bottom and the bridge of the nose also increases, so that the inclination angles α and β gradually increase in a direction away from the flange 602, but the face support 6 of the virtual reality device not only contacts the bridge of the nose, but the inclination angles α and β begin to gradually flatten as one transitions to a position near the cheeks to accommodate the facial structure of the wearer.

On the side contact sections 604 of the face-contacting portion 63, the inclination angles α and β gradually decrease in a direction away from the middle contact section 605. for the side contact sections 604, at positions gradually away from contact with the bridge of the nose, there is a gradual transition to the cheekbone positions of the wearer along both sides of the bridge of the nose.

The connecting side 634 is further provided with an inner edge support surface 639 connecting the abutment surface 636 and the connecting surface 6382 at the position of the inner edge 631.

In some embodiments of the present application, the abutment surface 636 is connected to the outer edge support surface 637 at a location on the side of the abutment curve 635 near the outer edge 632; at the connecting position of the attaching surface 636 and the outer edge supporting surface 637, a smooth transition curved surface is formed. In this embodiment, the smooth transition curved surface can form a transition between the attachment surface 636 and the outer edge support surface 637, so that not only can the face structure be attached sufficiently, but also the shading effect at the contact position can be further improved by using the characteristic that the attachment curve 635 has the maximum thickness.
