BEST MODE FOR CARRYING OUT THE INVENTION

In order to solve the problem that the current augmented reality headset cannot use the mobile terminal and display a single defect, the present invention provides a display enhanced display.

For a better understanding of the technical features, objects and effects of the present invention, the embodiments of the present invention are described in detail with reference to the accompanying drawings.

Referring to FIG. 1 to FIG. 6 , the enhanced display head display 10 of the present invention comprises an accommodating cavity 11 , an optical lens 13 , a curved mirror 15 , a dust mirror 17 , a bracket 18 and a casing 19 , and the accommodating cavity 11 is disposed on the casing 19 . Upper part. The augmented reality head 10 can be slid over the bracket 18, and the augmented reality head 10 can be secured to the upper portion of the bracket 18 and the lower portion of the bracket 18, respectively. When the augmented reality head 10 is fixed to the lower portion of the bracket 18, the light emitted by the augmented reality head 10 can reach the human eye to produce an augmented reality effect. The mobile terminal 20 can be placed in the accommodating cavity 11 with the display screen facing downward. An optical lens 13 is disposed below the accommodating cavity 11, and the optical lens 13 is a convex lens that can condense light emitted from the display screen 112 of the mobile terminal 20, and the optical lens 13 is disposed above the curved mirror 15. The curved mirror 15 is a semi-lens, and external light can enter the interior of the enhanced display head 10 through the curved mirror 15, and the enhanced display head 10 is passed through the dustproof mirror 17. The curved mirror 15 can simultaneously reflect the light emitted by the mobile terminal 20. When the light emitted by the mobile terminal 20 passes through the curved mirror 15, a part of the light is refracted, and the enhanced display head 10 is passed through, and the other part is reflected and passed through the dustproof. The mirror 17 enters the field of view of the user. After the mobile terminal 20 is placed in the accommodating cavity 11, a portion of the display screen 112 of the mobile terminal 20 is exposed outside the enhanced display head 10. A portion of the display screen of the mobile terminal 20 exposed to the outside of the enhanced display head display 10 is provided with a virtual operation button. The outer surface of the curved mirror 15 can be provided with a single-sided anti-reflection film, which can increase the transmittance of external light on the one hand, and enhance the reflective performance inside the curved mirror 15 on the other hand, thereby further optimizing the display effect. The dustproof mirror 17 is disposed at a position close to the human eye after wearing the enhanced display head display 10. The dustproof mirror 17 is made of a material having a relatively high light transmittance, preferably an anti-reflective glass and a PMMA acrylic material, and the anti-reflective glass has high safety. PMMA acrylic material has good light transmission. Here, ordinary glass is not used as the material for dust mirrors. On the one hand, the light transmittance of ordinary glass is not as good as PMMA acrylic material, and on the other hand, because ordinary glass is relatively poor in safety, cracking may cause harm to the human eye. The reflective glass is generally tempered glass, and the possibility of chipping is small. The main function of the dust mirror 17 is to seal the enhanced display head 10 to prevent dust from entering the enhanced display head 10 to cause contamination of the optical components.

As shown in FIG. 3, a display screen 112 is also included, the display screen 112 being disposed above the optical lens. The curved mirror 15 can simultaneously reflect the light emitted by the display screen 112. When the light emitted by the display screen 112 passes through the curved mirror 15, a part of the light is refracted, and the augmented reality helmet 10 is worn out, and the other part is reflected and passed through the dust mirror. 17 enter the user's field of vision. The display screen 112 of the augmented reality helmet 10 emits a display image, and the light of the display image is advanced toward the curved mirror 15 through the refraction of the optical lens 13, and the light is reflected by the curved mirror 15 and then enters the human eye for imaging.

In the present invention, the reflecting device is a plane mirror, the mirror 15 is a plane mirror, the mirror 15 can reflect the light emitted by the mobile terminal 20, and the light emitted by the mobile terminal 20 passes through the mirror 15 and all reflect and pass through The dust mirror 17 enters the field of view of the user. The use of a flat mirror instead of a curved mirror prevents the visual distortion caused by excessively concentrated light from the curved mirror or the out-of-focus caused by excessively diverging light.

In the present invention, the reflecting device is a concave mirror, the curved mirror 15 is disposed at a lower portion of the virtual reality helmet 10, facing the line of sight direction, the curved mirror 15 is a concave mirror, and the curved mirror 15 can reflect the light emitted by the display screen 112. When the light emitted by the display screen 112 passes through the curved mirror 15, all of the light is reflected and passes through the dust mirror 17 to enter the user's field of view.

As shown in FIG. 5, in the present invention, a movable hood 16 is further included, and the movable hood 16 can be moved up and down, and the light-reflecting device and the light-transmitting process are respectively performed on the light-reflecting device. It is very convenient to switch between the virtual reality and the augmented reality by switching the shading state and the light transmission state through the setting of the movable hood. When the movable hood 16 is in the light-shielding state, the movable hood 16 can greatly reduce the light transmittance of the curved mirror 15, and the curved mirror 15 functions as a plane mirror. At this time, the augmented reality head display 10 can realize the virtual reality helmet. Function to achieve full immersion.

The mirror is a half lens. When the movable hood performs light transmission processing on the mirror, external light penetrates the mirror and enters the human eye to form an image, and the light emitted by the mobile terminal is superimposed and imaged. The light emitted by the mobile terminal is refracted by the optical lens and then reflected by the reflective device into the observer's eye.

Referring to FIG. 7, when the user needs to communicate with the outside world or temporarily does not need to use the augmented reality head display 10, the augmented reality head display 10 can be slid along the bracket 18 to the upper portion of the bracket for fixing, so that the user's field of vision is clearer. There is no obstruction, which makes it easier for the user to communicate with the outside world, and it is also convenient for the user to switch between the two states at will.

Please refer to FIG. 8. FIG. 8 is a schematic diagram of an optical path of the enhanced display head display 10 of the present invention. There are mainly two optical paths, which are a display optical path and an external optical path. First, the light path is displayed. When the user wears the enhanced display head 10 and starts to use, the mobile terminal 20 that enhances the display head 10 emits a display image, and the light of the displayed image advances toward the curved mirror 15 through the refraction of the optical lens 13. After the light is reflected by the curved mirror 15, it enters the human eye to form an image. The external light path is relatively simple, and the external light penetrates the curved mirror 15 and the dust mirror 17 to enter the human eye. Imaging in the human eye is the effect of superimposing the light path and the external light path, so that an augmented reality effect can be produced. Since the display area of the mobile terminal 20 is much larger than that of the conventional augmented reality display component, a fine display effect can be produced, which is not possible with an ordinary enhanced display device.

Also included is an adjustment lens, which is a concave lens, a convex lens. The dustproof mirror 17 is replaced with an adjustment lens 27, which is an optical lens, which may be a convex lens or a concave lens. When we increase the focal length of the optical lens 13 for visual effects, the adjustment lens 27 is arranged as a concave lens, so that the light does not become too concentrated and can not be seen clearly when reaching the human eye; when we want to reduce the mobile virtual reality head When the volume of the optical lens 13 is reduced by 10, the adjustment lens 27 is provided as a convex lens, so that the light does not become too divergent and cannot be seen clearly when it reaches the human eye.

Compared with the prior art, the present invention utilizes the positional arrangement of the accommodating cavity 11, the optical lens 13, and the curved mirror 15, and the light of the display screen of the mobile terminal 20 passes through the optical lens 13 and the curved mirror 15 to enter the eye. The convergence of the light by the optical lens 13 and the convergence of the curved mirror 15 with the light are greatly reduced in the area of the display screen used for display, making the entire enhanced display head 10 lighter. The upper and lower accommodating chambers 11, the optical lens 13 and the curved mirror 15 cause the original lateral light path portion to be transferred to the longitudinal direction, saving space, and the torque for enhancing the display head 10 is reduced, and the pressure on the head is changed accordingly. Small, making the wearing enhanced display head 10 more comfortable. The curved mirror 15 is used instead of the ordinary mirror because the curved mirror can further converge the light and reduce the optical path, so that the volume of the enhanced display head 10 can be made smaller, further achieving the purpose of lightness. The external light penetrates the curved mirror 15 and the dust mirror 17 into the human eye, and is superimposed with the light emitted by the mobile terminal 20 to form an augmented reality image. The arrangement of the dust mirror 17 can seal the enhanced display head 10 to prevent dust from entering the enhanced display head 10 and causing contamination of the optical components. The dustproof mirror 17 is made of anti-reflective glass to enhance light transmittance while being safe and durable. The dustproof mirror 17 is made of PMMA material, which can increase the light transmittance and make the display effect better. The one-side anti-reflection film disposed outside the curved mirror 15 can increase the transmittance of external light on the one hand, and enhance the reflective performance inside the curved mirror 15 on the other hand, thereby further optimizing the display effect. A part of the display screen of the mobile terminal 20 is exposed on the outer side of the enhanced display head display 10 and the virtual button can be conveniently controlled and operated while using the enhanced display head display 10, so that the playability is greatly increased and is very convenient. At the same time, since a part of the mobile terminal 20 is exposed on the outside of the enhanced display head 10, it is convenient to directly take out the mobile terminal 20 to adjust and set it. The augmented reality head display 10 can be fixed on the upper and lower portions of the bracket 18, facilitating the user to switch in real time.
