The invention provides a pupil distance adjusting mechanism.
Referring to fig. 1 to 3, in an embodiment of the present invention, the pupil distance adjusting mechanism includes a mounting frame 10, a lens barrel 30, and an adjusting structure 50. The two lens barrels 30 are arranged on the mounting rack 10 side by side and can slide relative to the mounting rack 10 in the parallel direction of the two lens barrels 30; the two adjusting structures 50 are respectively arranged corresponding to one of the lens cones 30, each adjusting structure 50 comprises a threaded rod 51 and a hand wheel 52, one end of each threaded rod 51 in each adjusting structure 50 is in threaded connection with the corresponding lens cone 30, and the other end of each threaded rod 51 is connected to the hand wheel 52; the hand wheel 52 in the adjusting structure 50 is driven to rotate by an external force to drive the driving threaded rod 51 to rotate, so as to drive the corresponding lens barrels 30 to slide in the side-by-side direction of the lens barrels 30.
In an embodiment of the present invention, the mounting bracket 10 may be used to mount the lens barrel 30 and the adjusting structure 50, etc. so that the components of the pupil distance adjusting mechanism can be assembled together to form a whole. The mounting frame 10 may be a plate structure, or may be a combined structure of a plurality of plates, or a combined structure of a plurality of columns, and the present application does not limit the specific structure and shape of the mounting frame 10, and may be used to mount and carry the lens barrel 30 and the adjustment structure 50. The lens barrels 30 are arranged side by side in the mounting frame 10, and the specific form is that the axes of the lens barrels 30 are parallel, and the distance between the axes of the lens barrels 30 can be defined as the interpupillary distance, so that the adjustment of the interpupillary distance can be realized by adjusting the distance between the lens barrels 30. The adjustment structure 50 can be used to drive the lens barrels 30 individually to achieve adjustment of the interpupillary distance. In particular, a hand wheel 52 in the adjustment mechanism 50 may be used to provide an operating position for a user to apply force to drive rotation. Then, the rotating hand wheel 52 can drive the threaded rod 51 connected with the hand wheel to rotate, and the threaded rod 51 is matched with the threads of the lens barrel 30, so that the lens barrel 30 can slide along the axial direction of the threaded rod 51. Wherein, the threaded rod 51 and the hand wheel 52 of the adjusting structure 50 can be at least connected to the mounting frame 10, so as to support the whole structure of the adjusting structure 50.
When the pupil distance adjusting mechanism in the technical scheme of the invention is used, the hand wheel 52 of the adjusting structure 50 is driven to rotate, so that the hand wheel 52 can drive the threaded rod 51 to rotate. One end of the threaded rod 51, which is far away from the hand wheel 52, is in threaded connection with one lens barrel 30, so that the rotating threaded rod 51 can drive the lens barrel 30 in threaded connection with the threaded rod to slide relative to the mounting frame 10, thereby realizing adjustment of the distance between the lens barrels 30, namely adjustment of the interpupillary distance. In addition, since the pupil distance adjusting mechanism in this embodiment drives the lens barrels 30 through the adjusting structures 50, in the pupil distance adjusting process, a mode of driving the lens barrels 30 to move simultaneously through the adjusting structures 50 or a mode of driving one lens barrel 30 to move only through one of the adjusting structures 50 may be selected according to the actual use situation. So make interpupillary distance adjustment mode comparatively diversified and the flexibility of reinforcing interpupillary distance adjustment to the convenience of interpupillary distance adjustment process has been improved.
Further, the adjusting structure 50 in the interpupillary distance adjusting mechanism in this scheme is realized driving the lens barrel 30 by the threaded rod 51 and the lens barrel 30 being in threaded connection, and the threaded transmission has the advantages of stability and reliability, thereby being beneficial to improving the stability of the lens barrel 30 in the sliding process of interpupillary distance adjustment. Meanwhile, the thread transmission also has the advantage of self-locking, and the lens barrel 30 can be automatically locked after the threaded rod 51 drives the lens barrel 30 to be adjusted in place. Thus, a structure for locking the lens barrel 30 after being adjusted in place is not required to be additionally arranged, so that the integral structure of the pupil distance adjusting mechanism is simplified, the convenience of manufacture is improved, and the manufacturing cost is reduced. In addition, the threaded rod 51 is driven to rotate by a hand wheel 52, and the hand wheel 52 is driven to rotate by a manual external force applied by a user. Therefore, the user can conveniently control the pupil distance adjusting process, and artificial controllability in the pupil distance adjusting process is improved.

In the present embodiment, the transmission ratio of the transmission assembly 53 can be expressed as a ratio of the rotation speed of the hand wheel 52 and the rotation speed of the threaded rod 51. Therefore, the transmission ratio is less than 1, which means that the rotation speed of the hand wheel 52 is less than the rotation speed of the threaded rod 51, and further the acceleration effect is achieved in the process that the hand wheel 52 drives the threaded rod 51, so that the lens barrel 30 can be rapidly driven to move to a corresponding position to complete the pupil distance adjusting process. The required operating time of the pupil distance adjusting process is also greatly shortened, so that labor can be saved, and the convenience of the pupil distance adjusting process is further improved.

Further, a bearing 63 is embedded in the support base 61, and the hand wheel 52 is inserted into the bearing 63 through the insertion column 521. Because rolling friction is arranged between the inner ring and the outer ring of the bearing 63, when a user drives the hand wheel 52 to rotate relative to the supporting seat 61, rolling friction force is arranged between the inner ring and the outer ring, the friction coefficient at the moment is relatively small, so that the smoothness of the hand wheel 52 in the rotation adjusting process is improved, and meanwhile, the effect of saving labor can be achieved due to the fact that the resistance is reduced, and convenience in the pupil distance adjusting process is improved. The cross section of the insertion column 521 on the hand wheel 52 inserted into the bearing 63 may be non-circular, so as to reduce the possibility of relative rotation between the two.

The guide structure 70 may include a guide rod 71, the guide rod 71 is disposed on the mounting rack 10, and the guide rod 71 extends along the sliding direction of the lens barrel 30 and penetrates through the lens barrel 30. At this time, since the guide rod 71 passes through the lens barrel 30, the lens barrel 30 moves only along the extending direction of the guide rod 71 during being driven by the respective adjusting structures 50, thereby guiding the sliding of the lens barrel 30. Of course, the present application is not limited thereto, in other embodiments, the guiding structure 70 may also include at least two rolling members 73, where the two rolling members 73 are respectively rotatably disposed on the lens barrel 30 (that is, one lens barrel 30 may be provided with one rolling member 73, or may be provided with two or more rolling members), the mounting frame 10 is provided with a guiding slot 11 at a position corresponding to the two rolling members 73, the guiding slot 11 extends along the sliding direction of the lens barrel 30, and at least two rolling members 73 are all accommodated in the guiding slot 11.

In addition, since the rolling member 73 is in rolling contact with the guide groove 11, rolling friction with a relatively small friction coefficient can be formed between the two, which is beneficial to reducing the friction force between the two and improving the smoothness of the sliding of the lens barrel 30. The labor-saving effect can be further achieved, and the convenience of the pupil distance adjusting process can be further improved. Wherein, the rolling member 73 can be a roller, please refer to fig. 1 and fig. 2 in combination; of course, it can be a ball bearing, please refer to fig. 7 and 8 in combination.
