Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and implementation
Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain this
Utility model, is not used to limit the utility model.
Refer to Fig. 1-Fig. 7, the head-mounted display apparatus 100 that the utility model preferred embodiment is provided, its specifically with
Mobile terminal (such as mobile phone) is used cooperatively, and the head-mounted display apparatus 100 include main body frame 10, on main body frame 10
Optical system, wherein the optical system of the present embodiment includes two optical mirror slip groups 20, and each optical mirror slip group 20 distinguishes
Including Fresnel Lenses 21 and positive lens 22.Wherein described positive lens 22 is common lens, and plano-convex is preferably in embodiment
Non-spherical lens.
It is appreciated that the Fresnel Lenses is in image formation by rays, because the surface of its Fresnel surface is serrated,
Its light is difficult to focus on, and spherical aberration and off-axis aberration are difficult to correct so that when alone Fresnel Lenses is imaged, and its visual field is big,
But image quality is poor；And during alone non-spherical lens, need to increase the thickness of the lens while increase of its angle of visual field, in
This simultaneously, the transmitance of the light of the lens will decline, correspondingly, to the lens shaping prepare mould machining accuracy will
Ask high.Therefore, the optical mirror slip group 20 of the present embodiment is specifically that Fresnel Lenses 21 is applied in combination with positive lens 22.
Specifically, the Fresnel Lenses 21 is oppositely arranged with positive lens 22, and the Fresnel Lenses 21 is away from just
One side end face of lens 22 is set to plane, and another side end face is set to the Fresnel surface of radial symmetric, and the positive lens 22 exists
Plane is set to away from a side end face of Fresnel Lenses 21, another side end face is set to aspherical.Wherein described Fresnel is saturating
Can be connected with gluing between mirror 21 and positive lens 22, it is also possible to non-glued setting.The present embodiment assembles the optical mirror slip group 20
When being used on to main body frame 10, it is the angle of visual field for controlling optical system to take the lead in towards the Fresnel Lenses 21 of human eye, and
The positive lens 22 of display screen is chief ray angle for controlling optical system, it is necessary to explanation, moves on towards mobile terminal
The light of dynamic terminal display screen first passes through positive lens 22, by the adjustment of main optical angle, then injects Fresnel Lenses 21
By after angle of visual field adjustment, finally injecting human eye.It is applied in combination with lens 22 by by Fresnel Lenses 21, the wear-type can be made
The whole optical system of display device 100 is frivolous；Have visual field big simultaneously, the characteristics of good imaging quality.And then ensure that the head
The small volume of formula display device 100, lightweight is worn, and visual field is big, good imaging quality.Simultaneously as the Fresnel Lenses 21 with
The both sides outer face of positive lens 22 is disposed as plane, so facilitates the production system to Fresnel Lenses 21 and positive lens 22
It is standby, and it is easy to cleaning of the people during follow-up use, further meet the use demand of people.
When the Fresnel Lenses 21 of the present embodiment is applied in combination with positive lens 22, it meets equation below：
Wherein：
Z, is to be made with reference to the shift value away from optical axis with surface fixed point in r positions along optical axis direction；
C, is radius of curvature；
R, is the lens height；
K, is circular cone coefficient；
a4,a6,a8,a10,a12,a14,a16, the asphericity coefficient of respectively every time.
Two panels lens are according to different materials just recoverable aberration, and the scheme of single element lens can not correcting chromatic aberration.
The scheme of simple lens is substantially better than during big view field imaging.The scheme combined with positive lens 22 using Fresnel Lenses 21 is reduced
Mirror thickness, increases light penetration.The free degree of increased design, aberration correction is more preferable, and recoverable optical system color
Difference, scheme of the lens imaging quality better than simple lens.
On the one hand, in order to be suitable to the mobile terminal of different specification size size, the head-mounted display apparatus 100 of the present embodiment
It is specific on main body frame 10 that an equipment fixed mechanism 30 is set, to clamp mobile terminal in the outside of optical system.Wherein, institute
Stating equipment fixed mechanism 30 includes two pieces of clamp clips 31 being oppositely arranged, in a vertical manner the screw rod on two pieces of clamp clips 31
32, and for adjusting two pieces of knobs 33 of the spacing of clamp clip 32；The screw rod 32 is respectively with two pieces of clamp clips 31 with screw thread side
Formula is connected, and the screw rod 32 and two pieces of threaded connections of clamp clip 31 are in opposite direction, and the knob 33 is integrally fixed at screw rod 32
On, in the present embodiment, the screw rod 32 is specifically provided in two pieces of middle parts of clamp clip 31.So adjusted with knob 33
During the spacing of two pieces of clamp clips 31, when rotating screw rod 32 toward a direction, because the screw rod 32 is different from two pieces of clamp clips 31
Under threaded connection direction, two pieces of clamp clips 31 can be driven synchronously to be clamped to center or synchronous release, this ensures that thered
, when spacing fixed cellular terminal is adjusted, the axis of its mobile terminal is with whole optical system all the time for the equipment fixed mechanism 30
Alignment, and there is no the movement of upper-lower position.
In the present embodiment, a shield bars 11 are provided with the main body frame 10, the shield bars 11 are arranged on two
Position between optical mirror slip group 20, is separated with the display screen for being opposite to mobile terminal on equipment fixed mechanism 20 so that
The images of left and right eyes of user can only correspond to the picture of the display screen wherein side for receiving mobile terminal by optical system.
On the other hand, in order to be applicable the difference of its interocular distance of different users, the head-mounted display apparatus of the present embodiment
100 also include interpupillary adjustment mechanism 40, it will be understood that 20 groups described of two optical mirror slips are inlaid in interpupillary adjustment mechanism respectively
On 40.Specifically, the interpupillary adjustment mechanism 40 includes two lens frames 41 being oppositely arranged, and for adjusting two mirrors
The regulation gear 42 of the spacing of piece framework 41, is respectively arranged with tooth bar 43, and each eyeglass on lens frame 41 described in two of which
