The first gear drives the first lens frame to rotate, and the first rack and the second rack coupled with the first gear move towards opposite directions respectively, so that the center distance between the first lens frame and the second lens frame is reduced.
The first gear is coupled with the first rack and the second rack, so that when the first gear rotates, the first rack and the second rack are driven to move horizontally at the same time, the moving directions of the first rack and the first gear are the same, and the moving directions of the first rack and the second rack are opposite. Because, first rack is on first lens frame, and the second rack is on second lens frame, so the first rack that removes drives first lens frame and removes with the direction, and the second rack that removes drives second lens frame and removes with the direction, and it is visible, the moving direction of first lens frame and second lens frame is also opposite.
It can be understood that when the first lens frame and the second lens frame move towards each other, that is, the central distance between the first lens frame and the second lens frame is reduced, that is, the interpupillary distance is reduced; when first lens frame and second lens frame reverse movement, the central distance that also increases first lens frame and second lens frame promptly, increase interpupillary distance promptly.
In the embodiment of the invention, the coaxial gears with the diameter smaller than that of the roller are integrated on the roller, so that the torsion required during adjustment is reduced, the finger adjustment is easy, the accuracy of pupil distance adjustment is improved, and meanwhile, the gears are integrated for use, so that the cost and the space are saved.
For the method embodiment, since it is basically similar to the apparatus embodiment, the description is simple, and for the relevant points, refer to the partial description of the method embodiment.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
All the embodiments in the present specification are described in a related manner, and the same and similar parts among the embodiments may be referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the system embodiment, since it is substantially similar to the method embodiment, the description is simple, and for the relevant points, reference may be made to the partial description of the method embodiment.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
Claims (1)
1. The virtual reality equipment interpupillary distance adjusting method is applied to a virtual reality equipment interpupillary distance adjusting device, and the device comprises: the adjusting mechanism comprises an adjusting structure, a first gear, a first lens frame, a second lens frame and a shell; a first rack is arranged on the first lens frame; a second rack is arranged on the second lens frame; wherein the first gear is coupled between the first rack and the second rack, the adjustment structure being connected with the first rack; the adjustment structure includes: the adjusting structure, the first gear, the first lens frame and the second lens frame are packaged in the shell; the method comprises the following steps:
when a user operates the adjusting structure, the roller rotates to drive a second gear coaxially connected with the roller to rotate;
the rotating second gear drives a third gear coupled with the second gear to rotate;
the first gear rotates under the drive of a rotating third gear, wherein the diameter of the second gear is smaller than that of the roller wheel, so that the torsion required during adjustment is reduced and the finger operation is easy, the diameter of the second gear is smaller than that of the third gear, and the diameter of the third gear is larger than that of the first gear;
the first gear and the second gear are driven by the rotating first gear to move towards the direction away from the first gear respectively, so that the central distance between the first lens frame and the second lens frame is increased; or
The first gear drives the first lens frame to rotate, and the first rack and the second rack coupled with the first gear move towards opposite directions respectively, so that the center distance between the first lens frame and the second lens frame is reduced.
