Description

VR glasses

Technical Field

The utility model relates to a virtual reality technical field especially relates to a VR glasses.

Background

With the rapid development of science and technology, more and more digital products such as virtual reality equipment and intelligent wearable equipment are produced, and the intelligent life forms the development trend of the future society. And the human-computer interaction system forms an important part of intelligent life.

In a virtual reality device, VR glasses constitute an important part. VR glasses, i.e. Virtual reality heads, are products integrated by using simulation technology and various technologies such as computer graphics, man-machine interface technology, multimedia technology, sensing technology, network technology, etc., and are a new man-machine interaction means created by computer and the latest sensor technology.

VR glasses that can contact in the market at present generally divide into three types, and external head shows equipment, the first equipment that shows of integral type, mobile end show equipment. The mobile terminal display equipment is not provided with a built-in display, is used with the mobile phone and displays by using a display screen of the mobile phone; the integrated head display device, namely the VR all-in-one machine, comprises the display and the processing structure, can independently work without depending on external equipment, but the performance of the processing structure is often lower than that of a chip of a computer. In contrast, the external head display device has a built-in display, but generally has no processing chip, and needs to be connected to a high-performance PC through a data line, and after the image data is processed and generated by a processor of the PC, the image data is transmitted to the external head display device through the data line, and is displayed by the built-in display.

All VR glasses are worn on the head of a user, and the display image on the display screen is watched through the eyepiece by human eyes of the user. Its light path diagram is as shown in fig. 1, and the image on the display screen 10 assembles to user's eyes 40 after the first refraction of eyepiece 110, assembles to the vision macula lutea of people's eye through the second refraction of people's eye lens again on, forms clear image, and people's eye projects the image to the outside against the light path again, forms great virtual image 20 to produce the sensation of being personally on the scene.

Because the display screen 10 is disposed in the VR glasses and is therefore typically relatively small, the display screen 10 is typically only capable of clearly viewing the video images displayed therein when in close proximity to the human eye. The eyepiece 110 typically includes at least one convex lens for refracting and converging light rays emanating from the image on the display screen 10 to the eye 40 of the user, however, the eyepiece 110 must be in a well-balanced position between the display screen 10 and the eye to ensure that the image on the display screen 10 is just refracted and converged to the eye. Especially, the distance between the human eyes and the convex lens is different because of different users, which causes inconvenience that the VR glasses can only adjust the definition of the image on the display screen 10 by adjusting the distance between the glasses body and the human face.

Also, it is contemplated that the user can only adjust sharpness by moving the body of the VR glasses, or some degree of adjustment can be made by the change in curvature of the lenses in both eyes of the user. However, if the human eye is exposed to high curvature for a long time, it is easy to fatigue and even cause myopia. Moreover, only one display screen 10 is usually provided in the prior art, which limits the use of VR glasses, especially greatly weakens the real experience of spatially restoring the stereoscopic image, and especially for some users with unequal binocular vision, the experience from the VR glasses is seriously affected by the unclear display.

Moreover, VR glasses on the market are generally not intelligent enough, and when the VR glasses are temporarily taken off by a user, the playing cannot be automatically paused, so that the playing picture needs to be adjusted when the VR glasses are put on again.

The mirror body 100 comprises a light-tight hollow shell with a certain thickness, and specifically comprises an inner shell facing human eyes and an outer shell far away from the human eyes, and an edge shell clamped and connected with the inner shell and the outer shell. The side shell comprises an upper side surface, a lower side surface, a left side surface and a right side surface of the hollow shell. Two eyepiece holes are formed in the inner side shell and face the positions of human eyes 40 of a user, the two eyepieces 310 are inserted into and fixed in the eyepiece holes, and after the VR eyeglasses are worn by the user, the eyepieces 310 face the two eyes of the user respectively.

In the hollow housing, two display screens 320 are disposed near the outer housing, i.e., away from the eyepiece hole, but directly face the eyepiece hole, especially two display screens 320 for independently controlling the playing content, so that each eyepiece 310 directly faces one display screen 320, and thus the user's eyes can watch the corresponding display screen 320 through the corresponding eyepiece 310. The inside of hollow shell still sets up a rectangular shape circuit board 370, including two relative long sides and two relative short sides, circuit board 370 is fixed in the upper surface of display screen 320, circuit board 370 is connected with two display screen 320 electricity respectively through independent wire, carries independent video signal. In addition, the circuit board 370 sends the video images to be played on the left and right display screens 320, and a certain phase difference is provided, so that a stereoscopic effect is formed, and the experience of virtual reality is further increased.

As shown in fig. 3, a riser 380 is disposed between the display screen 320 and the eyepiece 310, and the riser 380 is higher than the display screen 320. For example, the riser 380 may be pre-fixed to the interior of the side casing. The two long sides of the circuit board 370 are parallel to the risers 380, and are defined between the outer casing and the risers 380 by the risers 380.

The two short sides of the circuit board 370 are respectively fixedly connected to an L-shaped fixing member 390, for example, by screwing or riveting. The L-shaped fixing member 390 is inserted and fixed between the display screen 320 and the side casing.

Therefore, by providing the riser 380 and the L-shaped fixing 390, the circuit board 370 can be securely disposed right above the display screen 320. Of course, the circuit board 370 may also be disposed directly below the display screen 320, as long as the position of the related fixing member is changed accordingly.

Inboard in this application indicates to wear behind the VR glasses, the VR glasses are facing the one side of people's face, and the outside indicates the one side of keeping away from people's face.

After the user wears the VR glasses, the user can watch the video image played on the display screen 320 through the eyepieces 310 by two eyes respectively.

Meanwhile, a data port 300 is further provided on the hollow housing, particularly on the inner housing, and the data port 300 is electrically connected to the circuit board 370 through an internal data line. The internal data line can either bypass the riser 380 or pass through the riser 380. And are not intended to be limiting herein.

The specific structure and optical path diagram of each eyepiece 310 are shown in fig. 4, and each eyepiece 310 includes a cylindrical opaque barrel 330, and any light cannot leak between the eyepiece 310 and the eyepiece hole through a certain sealing measure, so as to ensure that external light cannot enter the inside of the hollow housing. For example, as shown in FIG. 2, the barrel 330 threadably engages the eyepiece aperture, using threads to block light. In the eyepiece hole, the eyepiece 310 can also move back and forth with a certain amplitude by rotating through the threaded connection so as to be adjusted to be completely fit with the human eye 40. In addition, a circle of opaque eye cover 316 is further disposed at one end of the barrel body 330 close to the eyes, and the eye cover 316 is made of flexible material, so that any light leakage gap is not left between the eyepiece 310 and the eyes 40, and the viewing effect is not affected.

In a preferred embodiment, when the outer wall of the barrel 330 is threaded 317 into the eyepiece opening, the eyecups 316 are frustum-shaped and flare-shaped to flare outward from the barrel to ensure a snug fit to the eyes 40 in order to ensure that the eyecups 316 will fit with a certain amount of pressure against the eyes of the viewer. Of course, the surface is also covered with a layer of flexible material to increase the comfort of the wearer. Thus, rotating the barrel 330 along the threads 317 moves the eyecup 316 to fully engage the person's eye 40.

Through setting up the opaque eye-shade 316 with the cavity casing, just can build the viewing environment of a complete isolation light between eyes 40 and display screen 320, build an opaque video image viewing range, increase user's experience of being personally on the scene. Furthermore, the appearance of the VR glasses is not affected, especially if metallic glossy glasses are used.

The specific structure of the eyepiece 310 is as shown in fig. 4, a movable convex lens 312 is arranged inside the barrel body 330 and perpendicular to the central axis of the barrel body 330, and may be a movable convex lens group. In a preferred embodiment, the movable convex lens 312 is preferably a plano-convex lens, i.e., comprising a planar side and a convex side, wherein the planar side is preferably oriented toward the display screen 320 and the convex side is oriented toward the human eye 40. The advantage that sets up to plano-convex lens is, compares in two-sided bellied convex lens, and thickness is thinner, saves space more, thereby can make eyepiece 310 is more frivolous in the axial to make whole VR glasses more frivolous small and exquisite, promote the comfort level that the user wore.

The side wall of the barrel 330 is provided with at least one positioning groove 313 with the same width, and the positioning groove 313 and the central axis are obliquely arranged, i.e. form an angle, and preferably form an acute angle larger than 45 degrees.

Also, in a more preferred embodiment, the number of the positioning grooves 313 is more than 1, and in this case, each of the positioning grooves 313 is parallel to each other in the circumferential direction and is equidistantly distributed on a circumference of the barrel 330 perpendicular to the central axis.

Accordingly, the movable convex lens 312 is disposed inside the barrel 330, as shown in fig. 4. The method specifically comprises the following steps: at least one positioning post 314 is fixedly connected to the outer edge of the movable convex lens 312, and when there is more than one positioning post 314, it is also preferable that the positioning posts are equidistantly spaced apart from each other and disposed on the circumference of the outer edge of the movable convex lens 312.

Moreover, each positioning post 314 corresponds to one positioning groove 313, and the diameter of each positioning post 314 is equal to the width of the positioning groove 313, so that when the free end of each positioning post 314 extends into the positioning groove 313, the positioning post 314 can be ensured to move only along the length direction of the positioning groove 313, that is, the movable convex lens 312 advances or retreats along the central axis while rotating around the central axis, so as to change the distance between the movable convex lens 312 and the fixed convex lens 311. While ensuring that the movable convex lens 312 remains perpendicular to the central axis when moved back and forth.

For example, in a preferred embodiment, the positioning slots 313 and the positioning posts 314 are arranged in at least 3 groups which are separated, because three points determine a plane, which ensures the stability of the movable convex lens 312 in rotating and moving back and forth. It is ensured that the movement of the movable convex lens 312 in the direction of the central axis is stable and precisely controllable, which provides great convenience for the user to adjust the movable convex lens 312 for focusing.

In a preferred embodiment, a fixed convex lens 311 is further disposed at the outer port of the barrel 330, i.e. the port close to the display screen 320. By arranging the fixed convex lens 311, light emitted by the display screen 320 is firstly converged once, so that the video image can be further amplified. At this time, the length of the positioning groove 313 is determined by the focal length of the fixed convex lens 311, that is, two end points of the projection of the positioning groove 313 on the central axis should be located between the lens body of the fixed convex lens 311 and one-time focal length. The reason is that: considering that a user needs to view an image in a forward direction through VR glasses in general, the movable convex lens 312 needs to be disposed within the focal length of the fixed convex lens 311 so that the images on both sides of the two convex lenses are kept upright while the eyepiece 310 is shortened.

The fixed convex lens 311 is preferably disposed at a side close to the display screen 320, in other words, the fixed convex lens 311 is disposed between the movable convex lens 312 and the display screen 320, that is, at an end of the outer side of the lens barrel 330, because this can fix the distance between the eyepiece 310 and the display screen 320, that is, fix the position of the positioning groove 313, so that the whole VR glasses are more compact.

Since the light emitted from the display screen 320 can be precisely adjusted to fall on the human eye lens of the viewer with or without refraction by the stationary convex lens 311 regardless of the forward and backward movement of the movable convex lens 312 along the positioning groove 313 and always in the opening of the stationary positioning groove 313, thereby providing a clear viewing effect. Therefore, the user only needs to move back and forth to change the distance between the movable convex lens 312 and the human eyes 40, so that the clear view field effect can be adjusted, and the adjustment is easier.

In a better embodiment, in order to ensure that the movable convex lens 312 maintains parallel with the display screen 320 when moving back and forth along the central axis direction, as shown in fig. 5, the movable convex lens 311 may be fixed in a movable lens barrel 331, and the positioning posts 314 may be disposed outside the movable lens barrel 331, and the positioning posts 314 are also inserted into the corresponding positioning slots 313, that is, the movable lens barrel 331 is also moved back and forth by the movement of the positioning posts 314 in the positioning slots 313.

When positioning post 314 is inserted into positioning slot 313, an external force is applied to move positioning post 314. Therefore, in a more preferred embodiment, at least one positioning slot 313 is an adjusting slot 318 completely penetrating through the side wall, and accordingly, the positioning post 314 inserted into the adjusting slot 318 is an adjusting post 319, and the free end of the adjusting post 319 either directly extends out of the adjusting slot 318, is exposed out of the outer surface of the barrel 330, or extends out of the adjusting slot 318 by connecting an adjusting handle 315, thereby facilitating the user to perform toggle adjustment. One end of the adjusting handle 315 is connected to the free end surface of the adjusting post 319, and the other end of the adjusting handle 315 extends out and leaves the adjusting groove 318 for a certain length, so that the user can more easily toggle the adjusting post 319.

When the movable convex lens 312 or the movable lens barrel 331 is actually installed inside the lens barrel 330, because a tight fit is required and each positioning column 314 needs to be inserted into the positioning groove 313, the movable convex lens 312 or the movable lens barrel 331 can be first placed inside the lens barrel 330 and moved to a correct position, and then the interface position of each positioning column 314 is exposed in the positioning groove 313, and then the positioning column 314 is inserted into each interface from the outside of the positioning groove 313 and fixed with each interface by means of screwing, clamping, bonding or the like.

In a preferred embodiment, a flexible opaque material is sealed between the adjustment slot 318 and the adjustment post 319, and the flexible opaque material is tightly connected to the adjustment post 319 or the adjustment handle 315, so as to ensure that the adjustment post 319 or the adjustment handle 315 can move along the adjustment slot 318 and ensure that no new gap is created due to movement, thereby preventing light transmission.

As shown in fig. 6, the left and right ends of the lens body 100 are respectively provided with a connection post 151, the free end of the connection post 151 is provided with a socket 155, and the lens holder 150, including the lens legs mounted on the ears of the user or the lens string stretched on the head of the user, is inserted into the socket 155 and fixed, for example, screwed into the fixing holes 159 at the side of the connection post 151 by screws, so as to be detachably fixed.

In addition, in order to monitor whether the VR glasses are worn in real time, since the display screen 320 is usually small and needs to be viewed through the eyepiece 310, it is meaningful to play the VR video only after the VR glasses are worn. Specifically, a distance sensor 360 is arranged on the inner side shell in a direction opposite to the outer side shell, so that the distance between the human face and the VR glasses is detected in real time, and the distance sensor 360 is also electrically connected with the circuit board 370. The distance sensor 360 may be disposed in the middle of the inner side of the lens body 100 facing the human face, as shown in fig. 2, or may be disposed on the connecting column 151 on the side facing the human face.

In a further preferred embodiment, as shown in fig. 7, the outer housing and the inner housing are further connected to each other by a screw, in particular a longer screw. The distance sensor 360 is fixed to the head 367 of the screw whose shaft 366 passes through the screw holes in the inner housing and the riser 380 and is screwed into the screw hole 365 in the inner side of the outer housing. The screw holes in the riser 380 are preferably located between the two display screens 320.

In a preferred embodiment, in order to increase the wearing comfort of the user and adjust the distance between the eyepiece 310 and the human face to some extent, a nose pad may be further disposed between the two eyepiece holes at the middle of the lower portion of the lens body 100, and the nose pad may be detachably fixed to the lens body 100 by, for example, a nose pad bayonet 302 in fig. 2, or detachably fixed by at least one detachable fixing structure, such as a snap or a hook and loop.
