The Virtual Reality device is essentially a human-computer interaction device using a Virtual Reality technology, and common Virtual Reality devices, such as VR (Virtual Reality) glasses, can seal the senses of the user such as the vision, the hearing and the like of the outside world and guide the user to generate the sense of the user in a Virtual environment.

A typical virtual reality device is shown in fig. 23, and includes a mirror body 200 and a wearing hair band 100 symmetrically disposed on both sides of the mirror body 200, wherein a virtual reality optical assembly is disposed in the mirror body 200, and the virtual reality optical assembly includes a lens, a screen, and the like. A typical virtual reality device is, for example, one made using virtual reality optics as disclosed in US 20170017078B. When a user wears virtual reality equipment to experience a virtual environment, the hair band 100 is fixed on the head, and the screen of the virtual reality equipment is arranged in front of eyes through adjustment, and the frame of the mirror body 200 of the virtual reality equipment is attached to the face of the user. However, when wearing the virtual reality device, a gap is easily formed at a position where the frame of the mirror body 200 is attached to the face of the user, and at this time, if external light is incident on the screen of the virtual reality device through the gap, an image on the screen is weakened or unclear, or ambient light irradiates on eyes, which affects the visual effect of the user. Therefore, in order to prevent the incidence of external light, the light blocking assembly 300 is generally installed on the mirror body 200 of the virtual reality device.

A typical virtual reality device with a shading assembly is shown in fig. 24, and includes a mirror body 200, and a shading assembly 300 disposed on a side of the mirror body 200 adjacent to a face of a user; one end of the shutter assembly 300 is connected to the mirror body 200 and the other end of the shutter assembly 300 is adapted to fit the contours of the user's face. When the user is wearing virtual reality equipment to experience virtual environment, shading subassembly 300 closely laminates with user's face, utilizes shading subassembly 300 and user's face and virtual reality equipment's mirror body 200 to form airtight space, and external light can't enter into in the enclosure space to can not influence user's visual effect. In order to allow the user to experience the virtual environment for a long period of time, it is desirable to have a continuous enclosure between the shutter assembly 300, the user's face, and the mirror body 200 of the virtual reality device.

However, since the end of the light shielding assembly 300 connected to the mirror body 200 is a fixed end, and the end contacting with the face of the user is a movable end, the fixed end is not fixed, so that when the user wears the virtual reality device, the movable end is pressed when the face contacts the light shielding assembly 300, and the light shielding assembly 300 deforms, thereby damaging the formed closed space, and causing the light shielding assembly 300 to lose the light shielding effect, which affects the visual effect of the user. Therefore, the existing virtual reality equipment is easily pressed and deformed because the shading component cannot be fixed completely, so that the shading function is lost, and the using effect of the virtual reality equipment is influenced.

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.

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, in order to make the shading assembly beautiful in use, a material which has certain elasticity and is not easy to wrinkle, such as a cotton stretcher, a lycra and the like, can 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.

Referring to fig. 25, fig. 25 is a schematic structural diagram of a virtual reality device body provided in the present application.

Based on the disclosure of the above embodiment, the present application also provides a virtual reality device, which includes a virtual reality device main body 2 and a shading component 7. The shading assembly 7 comprises a shading piece 78 which accommodates the front end of the virtual reality device, and the shading piece 78 extends in the direction of the tail end of the virtual reality device and is fixed on the virtual reality device. The virtual reality device provided by the embodiment is different from the above embodiments in that the virtual reality device main body 2 includes a front shell 1, a rear shell 3, a frame 301 enclosed by the front shell 1 and the rear shell 3, and a left temple 5 and a right temple 4 symmetrically arranged at two ends of the rear shell 3; the rear case 3 and the mirror frame 301 form a housing chamber 46, and the housing chamber 46 is used for accommodating the optical system, the PCBA board 8 and the light-sensing components.

When a user wears the virtual reality equipment to experience a virtual environment, the rear shell 3 is opposite to the face of the user and is used for forming a closed space with the shading component 7 and the face of the user so as to prevent external light from entering and influencing the visual effect of the user; the front shell 1 is fixed on a mirror frame 301 of the virtual reality device through a buckle, and is used for forming a containing cavity 46 with the mirror frame 301 and the rear shell 3, so as to protect internal devices of the virtual reality device, such as an optical system, a PCBA (printed circuit board assembly) 8, a light sensing component and the like. When the virtual reality equipment falls, the front shell 1 firstly contacts with the ground, so that the impact generated by falling is absorbed, and the internal equipment of the virtual reality equipment is prevented from being damaged.

The left side arm 5 and the right side arm 4 are symmetrically arranged at two ends of the rear shell 3 and used for being put on ears of a user when being worn, so that the virtual reality equipment main body 2 is fixed in front of eyes of the user and is similar to glasses worn by people.

In order to prevent the virtual reality device main body 2 from being displaced on the human face due to the movement of the user and affecting the formation of the closed space, the virtual reality device is usually provided with a light shielding assembly 7. The front end fixing ring 77 of the light shielding assembly 7 covers the mirror frame 301, and the light shielding member 78 forms a closed space with the rear case 3 and the face of the user. When wearing, light-shading piece 78 and user's facial laminating, its one end is fixed with the mirror leg to guarantee to maintain the enclosure for a long time, avoid destroying the enclosure because of user's little action, make external light get into, influence user's visual effect.

In order to realize the locking connection of the visor 78 with the left and

right temples

5 and 4 to provide a long-term closed space, the connection of the visor 78 with the left and

right temples

5 and 4 needs to have a mutually matched structure to achieve the purpose of locking. In the present embodiment, the left temple 5 and the right temple 4 are collectively referred to as temples.

Specifically, as shown in fig. 26, the left temple 5 and the right temple 4 are respectively provided with through holes 51; the through hole 51 includes an entrance frame 511 provided outside the left temple 5 and outside the right temple 4, and a locking frame 512 provided inside the left temple 5 and inside the right temple 4; the entry frame 511 is used for the initial penetration of the connecting piece, the locking frame 512 is used for the termination penetration of the connecting piece, and the connecting piece can be fixed on the temple through the structural cooperation of the entry frame 511 and the locking frame 512.

The locking frame 512 on the left temple 5 is disposed opposite the locking frame 512 of the right temple 4 such that the entrance frame 511 is located outside the temple and the locking frame 512 is located inside the temple, i.e., the side of the left temple 5 and the side of the right temple 4 where the locking frame 512 is disposed face each other. The access frame 511 is communicated with the locking frame 512 so that the connecting piece can pass through to achieve the fixing purpose. The size of the entrance frame 511 is smaller than that of the locking frame 512, that is, the lateral width of the entrance frame 511 is the same as that of the locking frame 512, but the shapes of the entrance frame 511 and the locking frame 512 are different, and optionally, the entrance frame 511 is in the shape of a ball stud, the locking frame 512 is in the shape of a ring, and the longitudinal width of the locking frame 512 is larger than that of the entrance frame 511, so that the entrance frame 511 and the locking frame 512 form a locking groove 513. The locking recess 513 serves to lock one end of the connector to prevent the connector from sliding in the through hole 51, reducing the effect of the locking connection between the shade 78 and the temple.

As shown in fig. 27 and 28, the light shielding assembly 7 is sleeved on the frame 301 through the light shielding member 78; the shade 78 includes a first curved surface 75 for connecting with the right temple 4 and a second curved surface 76 for connecting with the left temple 5; the first curved surface 75 is provided with a first connection hole 701, and the second curved surface 76 is provided with a second connection hole 702.

Wherein, the connecting piece comprises a first connecting piece 71 and a second connecting piece 72, the first connecting piece 71 is used for fixing a first curved surface 75 and the right side arm 4, and the second wheel connecting piece 72 is used for fixing a second curved surface 76 and the left side arm 5.

Specifically, first connection hole 701 is connected to through hole 51 of right temple 4 through first connector 71, and first connector 71 passes through first connection hole 701 and through hole 51 at the same time to be fixed. Wherein, the first connecting piece 71 is penetrated through the entering frame 511 on the right temple 4 and fixed in the locking groove 513, so that the first curved surface 75 is locked on the right temple 4; the second connection hole 702 is connected to the through hole 51 of the left temple 5 through the second connector 72, and the second connector 72 is simultaneously inserted through the second connection hole 702 and the through hole 51 to be fixed. Wherein the second connecting member 72 is inserted through the entrance frame 511 of the left temple 5 and fixed in the locking recess 513, so that the second curved surface 76 is locked to the left temple 5.

Through the cooperation of first curved surface 75 and right side 4, and the cooperation of second curved surface 76 and left side 5, make light-shielding piece 78 and mirror leg carry out fixed connection, avoid making shading subassembly 7 compressive deformation because of user's action, destroy the enclosure space that originally forms. It can be seen that the virtual reality device with the locking function provided by the application can keep the closed space formed by the shading component 7, the rear shell 3 and the face of the user for a long time.

In order to allow the entry frame 511 and the locking frame 512 to form the locking recess 513 to fix the connecting member in the locking recess 513, thereby achieving the locking connection of the shade 78 and the temple, it is necessary that the entry frame 511 and the locking frame 512 have a structure to be fitted to each other.

Specifically, as shown in fig. 29, since the entry frame 511 may be alternatively shaped as a ball stud, the entry frame 511 includes a first circular curved surface 5111 at the ball end, a second circular curved surface 5114 at the pin end, two supporting surfaces 5113 at both sides of the pin, and two transition curved surfaces 5112 for connecting both sides of the ball end and the pin.

The first circular curved surface 5111 is a circular opening, two ends of the opening are respectively connected with a transition curved surface 5112, and the first circular curved surface 5111 is symmetrical along the transverse center line 5115 and used for enabling the connecting piece to penetrate through; the two transitional curved surfaces 5112 are symmetrical along the transverse center line 5115 for guiding the sliding direction of the connecting member. The connection point of the first circular curved surface 5111 and the transition curved surface 5112 is an inscribed intersection point corresponding to the two arcs, so that the first circular curved surface 5111 and the two transition curved surfaces 5112 form an inwardly convergent open circular ring shape.

The other end of each transition curved surface 5112 is connected to one end of a supporting surface 5113, so that the two supporting surfaces 5113 are parallel to each other and symmetrical along the transverse center line 5115. The support surface 5113 is used to provide a supporting force to the connector so that the connector can be fixed in the locking groove 513 by the clamping of the support surface 5113. The other ends of the two supporting surfaces 5113 are connected with a second circular curved surface 5114 together; the second rounded surface 5114 is symmetrical along the transverse center line 5115, and the second rounded surface 5114 is adapted to the shape of the connecting member, so that the U-shaped groove formed by the second rounded surface 5114 and the two supporting surfaces 5113 can lock the first connecting member 71 or the second connecting member 72.

In other embodiments, the first circular curved surface 5111 and the second circular curved surface 5114 may not adopt the circular arc shape shown in this embodiment, and may also adopt other shapes, which is not specifically limited in this embodiment. For the convenience of use of users, the circular arc is preferred, because the peripheral arcs of the circular arc are consistent and have no direction selectivity, so that the users do not need to consider the direction when fixing. In order to make the U-shaped groove and the connecting member seamlessly fit to increase the locking force, it is only necessary that the shape of the first and second circular

curved surfaces

5111 and 5114 is the same as the cross-sectional shape of the connecting member. For example, if the cross-sectional shape of the connector is square, the first and second

rounded surfaces

5111 and 5114 may also be flat surfaces.

The first round curved surface 5111 is positioned on one side of the left leg 5 and the right leg 4 away from the connecting rear shell 3; the second round curved surface 5114 is located on the left and

right temples

5 and 4 on the side near the connecting rear case 3. That is, the ball head of the ball head pin-shaped entering frame 511 faces the tail end of the glasses leg, and the pin faces the root of the glasses leg, so that the connecting piece passes through the first round curved surface 5111, moves in the channel formed by the two supporting surfaces 5113 in the direction of the second round curved surface 5114, that is, moves in the direction of the rear shell 3 until being attached to the second round curved surface 5114, and the light shielding piece 78 is locked on the glasses leg through the connecting piece by using the pulling force between the light shielding piece 78 and the glasses leg.

In order to make the light shielding member 78 generate a pulling force when it is locked to the temple and to improve the stability of the light shielding assembly 7 fixed to the temple, it is necessary that the distance from the connection holes provided in the light shielding member 78, such as the first connection hole 701 and the second connection hole 702, to the front end fixing ring 77 is slightly smaller than the distance from the second circular curved surface 5114 entering into the frame 511 to the front case 1.

In order to enable the coupling member to be locked on the second round-curved surface 5114, the radius of curvature of the second round-curved surface 5114 is required to be smaller than that of the first round-curved surface 5111; in order to increase the smoothness of the sliding of the connecting member from the channel formed between the two supporting surfaces 5113, the radius of curvature of the second circular curved surface 5114 is required to be equal to the distance L1 between the supporting surface 5113 and the transverse center line 5115, so that the connection between the supporting surface 5113 and the second circular curved surface 5114 is smooth, and the occurrence of the jamming when the connecting member is moved to be locked is avoided.

In order to form the locking recess 513 between the entrance frame 511 and the locking frame 512, the locking frame 512 is required to have a structure to be engaged with the entrance frame 511. Specifically, as shown in fig. 30, since the locking frame 512 may alternatively be annular in shape, the locking frame 512 includes a first semicircular face 5121 and a second semicircular face 5122 at both end portions of the annular shape, and two defining faces 5123 at a middle portion of the annular structure.

Two ends of the first semicircular surface 5121 are respectively connected with one end of a limiting surface 5123, two ends of the second semicircular surface 5122 are respectively connected with the other end of the limiting surface 5123, and the bending directions of the first semicircular surface 5121 and the second semicircular surface 5122 are opposite, so that the first semicircular surface 5121, the second semicircular surface 5122 and the two limiting surfaces 5123 form an annular structure. Since the locking frame 512 communicates with the access frame 511, the locking frame 512 is also symmetrical along the transverse centerline 5115.

The width H2 between the two limiting surfaces 5123 is greater than the width H1 between the two supporting surfaces 5113, so that the locking groove 513 is formed between the locking frame 512 and the entry frame 511 due to the position of the limiting surfaces 5123 opposite to the position of the supporting surfaces 5113. The locking groove 513 includes a sliding channel formed by the support face 5113, the defining face 5123, and the temple portion therebetween for sliding passage of the connector; the restricting frame is formed of a second rounded surface 5114, a second semicircular surface 5122, and a temple portion therebetween, for the sliding termination of the connector, defining the connector within the locking groove 513. In this embodiment, the locking recess 513 is U-shaped.

The first semicircular surface 5121 is opposite to the first circular curved surface 5111, and the two are communicated, and the connecting piece passes through the first circular curved surface 5111 and the first semicircular surface 5121 in sequence; the supporting surface 5113 is opposite to the limiting surface 5123, and the two surfaces are communicated to form a sliding channel, so that the connecting piece can slide along the sliding channel; the second semicircular face 5122 is opposite to the second circular curved face 5114, and the two are communicated with each other, and the connecting member is moved to the limiting frame by the sliding channel and then is stopped, so that the connecting member is locked in the locking groove 513. It can be seen that, when fixed, one end of the connector passes through the first connection hole 701 and the second connection hole 702 of the light shielding member 78, and the other end of the connector passes through the through hole 51 and moves in the through hole 51 in the direction toward the rear case 3, so that the connector is fixed in the locking recess 513, and thus the light shielding member 78 is fixed to the temples.

In an alternative embodiment, the first semicircular surface 5121 and the first circular curved surface 5111 have the same shape and size, the first semicircular surface 5121 and the second semicircular surface 5122 have the same shape and size, and the second semicircular surface 5122 and the second circular curved surface 5114 have the same shape and size, and the shape of the circular surfaces is matched with the cross-sectional shape of the connecting member, so that the connecting member can be tightly attached in the through hole 51, and the locking strength is increased. Illustratively, when the cross-sectional shape of the connecting piece is circular, the circular surfaces are all in a circular arc structure. If the cross-sectional shape of the connecting member is square or other shapes, the shape of the round surface is also square or other shapes, and the embodiment is not particularly limited.

At this time, the radius of the first semicircular surface 5121 is equal to the radius of the second semicircular surface 5122; the radius of the first semicircular surface 5121 is equal to the radius of curvature of the first circular curved surface 5111; and the locking groove 513 is formed for the entrance frame 511 and the locking frame 512 such that the lateral width H5 of the locking frame 512 is greater than the lateral width H6 of the entrance frame 511.

In another alternative embodiment, the first semicircular surface 5121 and the first circular curved surface 5111 have the same shape and different sizes, so long as the minimum size of the two is ensured to be larger than the cross-sectional width of the connecting member. The second semicircular surface 5122 has the same shape as the second circular curved surface 5114, but has a different size. The first semicircular surface 5121 and the second semicircular surface 5122 have the same shape and different sizes, so long as the size of the second semicircular surface 5122 is larger than that of the second circular curved surface 5114. The shape of the structure is matched with the cross section shape of the connecting piece, so that the connecting piece is tightly attached in the through hole 51, and the locking strength is increased.

In order to achieve a locking connection between the visor 78 and the temple, the temple is provided with a connecting element adapted to the structure of the through-hole 51, in addition to the entry frame 511 and the locking frame 512, which are structurally matched to one another.

Specifically, as shown in fig. 31, since the through holes 51 formed in the two temples have the same structure, and the two connecting holes formed in the light shielding member 78 have the same structure and position, the first connecting member 71 and the second connecting member 72 for connecting are also the same structure, and this embodiment only takes the structure of the first connecting member 71 as an example, and the structure and the obtained beneficial effects of the second connecting member 71 only need to refer to the first connecting member 71, and are not described herein again.

The first connector 71 is used to connect the right temple 5 and the first curved surface 75. The first connector 71 includes a first fixing buckle 711, a second fixing buckle 712, a locking buckle 714, and a support post 713. The first and second fixing buckles 711 and 712 are used to clamp the first curved surface 75, the locking buckle 714 is used to be fixed in the locking groove 513 on the temple, and the support pillar 713 is used to provide a clamping force to the first and second fixing buckles 711 and 712 and a supporting force to the locking buckle 714.

One end of the supporting pillar 713 is connected to the first fixing buckle 711 and the second fixing buckle 712, and the other end of the supporting pillar 713 is connected to the locking buckle 714. The supporting column 713 passes through the centers of the first fixing buckle 711, the second fixing buckle 712 and the locking buckle 714 in sequence, so that the axis of the first fixing buckle 711, the axis of the second fixing buckle 712, the axis of the locking buckle 714 and the axis of the supporting column 713 are coincident.

A first gap 715 is formed between the first fixing buckle 711 and the second fixing buckle 712, and the first gap 715 is used for fixing the first curved surface 75; the supporting pole 713 connects one ends of the first and second fixing

buttons

711 and 712 while passing through the first connecting hole 701 so that the first curved surface 75 is positioned between the first and second fixing

buttons

711 and 712, and the first curved surface 75 is clamped by the first and second fixing

buttons

711 and 712. The structure of the first fixing buckle 711 and the second fixing buckle 712 clamping the second curved surface 76 is referred to above, and will not be described herein.

A second gap 716 is formed between the second fixing buckle 712 and the locking buckle 714, and the second gap 716 is used for enabling the locking buckle 714 to pass through the through hole 51 on the left side arm 5 or the right side arm 4, so that the light shielding member 78 is fixed on the left side arm 5 and the right side arm 4 through the locking buckle 714.

When the visor assembly 7 is fixed to the temple, the first curved surface 75 of the visor 78 is fitted with the first connector 71 through the first coupling hole 701, and the second curved surface 76 is fitted with the second connector 72 through the second coupling hole 702. The first connector 71 and the second connector 72 respectively pass through the through holes 51 formed on the temple, i.e. the locking buckle 714 on the connector sequentially passes through the first round-curved surface 5111 and the first semi-round surface 5121, then the supporting post 713 part structure corresponding to the second gap 716 slides along the sliding channel towards the rear shell 3, and the locking buckle 714 and the supporting post 713 part structure are terminated in the limiting frame formed by the second round-curved surface 5114 and the second semi-round surface 5122, i.e. the locking buckle 714 is limited in the locking groove 513, and the shading piece 78 is fixed on the temple, i.e. the shading assembly 7 is in locking connection with the temple.

In order to enable the support post 713 part structure to move in the sliding channel, the width H4 of the second gap 716 corresponding to the support post 713 part structure is required to be less than or equal to the thickness of the left temple 5 or the right temple 4. The width H4 is less than or equal to the thickness of the temple, so that it is prevented that the length of the supporting post 713 is extended due to the width H4 being too large, and thus when the connector is inserted through and fixed to the temple, a protruding state is formed, which may contact the user's face and press the user's face, thereby easily causing a bad experience to the user. Meanwhile, the width H3 of the first gap 715 is smaller than the width H4 of the second gap 716, so that the supporting pillar 713 corresponding to the second gap 716 has a sufficient length to satisfy the above condition.

In order to enable the locking buckle 714 to simultaneously pass through the first round curved surface 5111 and the first semicircular surface 5121 and be limited in the limiting frame formed by the second round curved surface 5114 and the second semicircular surface 5122, the radius of the locking buckle 714 is required to be smaller than the radius of curvature of the first round curved surface 5111 and the radius of the first semicircular surface 5121; the diameter of the locking buckle 714 is greater than the width H1 of the two bearing surfaces 5113, and the diameter of the locking buckle 714 is less than the width H2 between the two limiting surfaces 5123. The maximum width of the locking catch 714 is less than the maximum width of the locking recess 513, which secures the locking catch 714 within the locking recess 513.

Further, in order to prevent the locking button 714 from contacting the human head when the protruding temple is close to the human head in the locked state, and thus causing a bad feeling to the user, it is preferable that the thickness of the locking button 714 is smaller than or equal to the depth of the locking recess 513, that is, the locking button 714 is accommodated in the locking recess 513 without being exposed.

Meanwhile, the width H1 of the two support surfaces 5113 is larger than the cross-sectional width of the support post 713 so that the support post 713 can move smoothly in the slide channel to avoid the occurrence of jamming when the sunshade assembly 7 is fixed to the temple.

The temples are provided with through holes 51 including an entrance frame 511 and a locking frame 512, and the entrance frame 511 and the locking frame 512 form a locking recess 513. The light shielding member 7 is provided with a first connector 71 fixed through a first connection hole 701, and a second connector 72 fixed through a second connection hole 702. The first connector 71 and the second connector 72 are secured within the locking recesses 513 by the interfitting of the through holes 51 in the respective temple arms, respectively, to lock the shutter assembly 7 to the temple arms. This virtual reality equipment has the locking function, and through the structure cooperation of through-hole 51 and connecting piece, with shading subassembly 7 locking on the mirror leg, make shading subassembly 7 can keep the closed form for a long time, avoid producing because of the pressurized and warp to form the enclosure space for a long time, make the user can experience virtual environment for a long time.
