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.

Referring to FIGS. 1-4 , the mobile virtual reality head-mounted display of the present invention includes a head-mounted display 10 , and the head-mounted display 10 includes a cover 12 , optical lenses 16 and a buffer device 18 . The protective cover 12 is arranged on the back of the head-mounted display 10 , that is, the side facing away from human eyes 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 may not have 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 disposed 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 . The mobile terminal 40 includes a display screen 401 .

Referring to FIGS. 5-6 , in the first embodiment of the present invention, the adjusting device 3 is arranged in the head display 10 , including a limiting plate 31 and a limiting block 35 . The limiting block 35 includes a limiting groove 351 for accommodating the mobile terminal 40 and a marking block 352 for marking the position of the limiting block 35 . One end of the marking block 352 is exposed outside the head-mounted display 10 , and a marking is provided on it, allowing the user to observe the position of the marking. A scale 354 is provided on one or both sides of the marking block 352 , and scales are engraved on the scale 354 , and each scale corresponds to a model of the mobile terminal 40 . The scale is set in advance. By calculating the optimal display position of different types of mobile terminals 40 and the length of the corresponding mobile terminal 40, the position of the corresponding scale can be obtained. When the mark on the mark block 352 reaches the corresponding scale, the mobile terminal 40 is at the best display position. 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. When the mobile terminal 40 is put into the accommodating cavity 103 , it abuts against the limiting block 35 , and one end of the mobile terminal 40 is inserted into the limiting groove 351 , so that the mobile terminal 40 is fixed in the limiting groove 351 . During the movement of the mobile terminal 40 to the inside, the limit block 35 is pushed to move inward by the mobile terminal 40, and the marking block 352 also moves from left to right thereupon. When the position is scaled, stop pushing the mobile terminal 40 inward. At this time, since the mobile terminal 40 is fully in contact with the buffer layer 105 , the frictional force between the mobile terminal 40 and the buffer layer 105 can limit the movement of the mobile terminal 40 .

Referring to Fig. 7-Fig. 8, the structure of the second embodiment of the present invention is generally the same as that of the first embodiment. The difference is that the adjustment device 3 further includes a limiting plate 31, and a plurality of teeth 313 are arranged on the limiting plate 31. The teeth 313 can assist in fixing the limit block 35; the limit block 35 further includes a positioning block 353 for assisting positioning; in this embodiment, there may be no limit slot 351. When the mobile terminal 40 is placed in the accommodating cavity 103, it abuts against the limit block 35. When the mobile terminal 40 moves inwardly, the limit block 35 is pushed by the mobile terminal 40 to move inwardly, and the marking block 352 also follows. Moving from left to right, when the marking on the marking block 352 reaches the scale position corresponding to the model of the mobile terminal 40 , stop pushing the mobile terminal 40 inward, and press the marking block 352 . The marking block 352 moves downward and drives the positioning block 353 to move downward together. The positioning block 353 is inserted into the gap between the teeth 313 to position the mobile terminal 40 . At this time, since the mobile terminal 40 is fully in contact with the buffer layer 105 , the frictional force between the mobile terminal 40 and the buffer layer 105 can limit the movement of the mobile terminal 40 .

Compared with the prior art, the present invention utilizes setting marks on the limit block 35 and cooperates with the set scales and scales to complete the adjustment of the best display position of the mobile terminal 40 during the process of placing the mobile terminal 40, avoiding the The complexity of the procedure caused by the adjustment after putting the mobile terminal 40 in, at the same time ensures that the display screen 401 can be in the best display position, so that the displayed image can normally undergo optical distortion through the optical lens 16, which improves the display effect and experience. . A limiting slot 351 is provided on the limiting block 35 , which can function to fix the mobile terminal 40 .

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.
