Detailed ways

In order to solve the defect that the adjustment of the current head-mounted display of the mobile terminal is not accurate enough, the present invention provides a virtual reality head-mounted display of the mobile terminal that can accurately adjust the mobile terminal.

In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

Please refer to Fig. 1-Fig. 2, the mobile terminal virtual reality head display of the present invention includes a head display 10, and the head display 10 includes a cover 12, and the cover 12 is arranged on the back of the head display 10, that is, the side facing away from the human eye after normal wearing . The head display 10 further includes an accommodating cavity 103 and a buckle cover 101. The accommodating cavity 103 is arranged inside the head display 10 for placing the mobile terminal 40. The buckle cover 101 can be fastened to the opening of the accommodating cavity 103. When placing the mobile terminal 40 , the buckle cover 101 can be opened, the mobile terminal 40 can be placed in the accommodating cavity 103 , and the buckle cover 101 can be fastened. A buffer layer 105 is provided in the accommodating cavity 103 . Since different mobile terminals 40 are not necessarily the same thickness, the buffer layer 105 can ensure that different types of mobile terminals 40 can be clamped to prevent shaking. The buffer layer 105 is generally arranged at the edge of the accommodating cavity 103 , so that it can closely contact with the edge of the mobile terminal 40 and prevent it from blocking the display of the mobile terminal 40 .

Referring to FIGS. 3-6 , the head-mounted display 10 further includes an optical lens 16 and a buffer device 18 . The mobile terminal 40 includes a display screen 401 . The head-mounted display 10 further includes an adjusting device 3 . The adjusting device 3 is arranged in the head-mounted display 10 and includes a limiting block 35 and a movable platform 36 . The limiting block 35 can slide on the movable platform 36 . A plurality of positioning blocks 361 are arranged on the movable platform 36 for positioning the limiting block 35 . The positioning block 35 is provided with a positioning slot 352 corresponding to the positioning block 361 . When the positioning block 35 slides on the movable platform 36 , the positioning block 361 can be fitted in the positioning slot 352 to fix the positioning block 35 . The first end of the limiting block 35 can abut against the mobile terminal 40 put in, and the second end is connected with a spring, and the spring can push the limiting block 35 back to the initial position when the mobile terminal 40 is taken out.

The positioning groove 352 cooperates with the positioning block 361 to define the position of the limiting block 35, and we can use this technical feature to adjust the position of the mobile terminal. We need to ensure that the mobile terminal 40 is in the best optical display position when it is put into the head-mounted display 10 to work, that is, the left and right images played on the display screen 401 are facing the left and right optical lenses 16 . Generally, when the projection of the vertical line connecting the centers of the left and right optical lenses 16 on the display screen 401 coincides with the symmetry axis of the display screen 401, we believe that the mobile terminal 40 is in the best display position. We can set the positions of the positioning groove 352 and the positioning block 361 according to this requirement to ensure that the mobile terminal 40 is in the best display position during normal use, thus saving the process of adjusting the left and right positions of the mobile terminal 40. The position of 40 can be in the best display position after being put into the head display 10 without adjustment. For example, we can set the position when the first positioning block 361 from the left is fitted with the first positioning groove 352 from the right as the position where the iPhone SE achieves the best display; The position when the first positioning groove 352 fits is set to the position where the iphone 6s achieves the best display; the position when the third positioning block 361 from the left is fitted with the first positioning groove 352 from the right is set as the iphone 6s plus To achieve the best display position, in this way, when we place different mobile terminals 40 into the head-mounted display 10, we only need to fit the corresponding positioning block 361 with the positioning groove 352, so that the mobile terminal 40 can be positioned neither to the left nor to the left. Also positioned to the right, images can be displayed with optimum display. In the process of pushing the mobile terminal 40 into the head-mounted display 10 , it is only necessary to know which positioning block 361 the positioning slot 352 fits with by feeling several obstacles encountered.

We can adjust the elastic force of the spring so that the spring can push the limit block 35 to reset alone, but cannot push the limit block 35 abutting against the mobile terminal 40 . When the mobile terminal 40 abuts against the limit block 35, the spring cannot simultaneously overcome the friction force between the limit block 35 and the mobile terminal 40, that is, the elastic force of the spring is smaller than the maximum friction between the limit block 35 and the mobile terminal 40 sum of forces. After the mobile terminal 40 is taken out, the spring can overcome the frictional force of the limiting block 35 and push the limiting block 35 to reset.

When the user uses the head-mounted display 10 , firstly, the button cover 101 is opened, and the mobile terminal 40 is put into the head-mounted display 10 , wherein the display screen 401 faces the viewer. The user pushes the mobile terminal 40 into the accommodating cavity 103 , and one end of the mobile terminal 40 abuts against the limiting block 35 . During the process of pushing the mobile terminal 40 , the limiting blocks 35 will respectively engage with several positioning blocks 361 distributed on the movable platform 36 , and only the positioning blocks corresponding to the mobile terminal 40 can be selected for engagement. At this time, we think that the position of the mobile terminal 40 is in the best display position. Fasten the buckle cover 101, and the headset 10 can be worn and used normally.

Compared with the prior art, the present invention uses the limit block 35 to adjust the position of the mobile terminal 40 to ensure that the position of the mobile terminal 40 is in the best display position, neither left nor right. Using the cooperation of the positioning block 361 and the positioning groove 352 can effectively position and fix the limiting block 35 . Setting the spring can reset the limit block 35 after use is completed. At the same time, limiting the size of the elastic force can prevent excessive elastic force from affecting the positioning. The setting of the buffer layer 105 can protect the mobile terminal 40 from being scratched on the one hand, and on the other hand can increase the friction force during the movement of the mobile terminal 40 to prevent the spring from affecting its positioning.

Embodiments of the present invention have been described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementations, and the above-mentioned specific implementations are only illustrative, rather than restrictive, and those of ordinary skill in the art will Under the enlightenment of the present invention, many forms can also be made without departing from the gist of the present invention and the protection scope of the claims, and these all belong to the protection of the present invention.
