The invention provides a pupil distance adjusting mechanism.
Referring to fig. 1 to 3 in combination, 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 side by side and can slide relative to the mounting frame 10 in the side by side direction of the two lens barrels 30; the two adjusting structures 50 are respectively arranged corresponding to one lens barrel 30, each adjusting structure 50 comprises a threaded rod 51 and a hand wheel 52, one end of the threaded rod 51 in each adjusting structure 50 is in threaded connection with the corresponding lens barrel 30, and the other end of the threaded rod is connected with 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 barrel 30 to slide in the side-by-side direction of the lens barrel 30.
In an embodiment of the present invention, the mounting frame 10 may be used to mount the lens barrel 30 and the adjustment structure 50, etc., so that the individual components of the pupil adjustment mechanism may be assembled in a relatively concentrated manner as a single unit. The mounting frame 10 may be a plate structure, or may be a combination structure of a plurality of plates, or a combination structure of a plurality of columns, and the specific structure and shape of the mounting frame 10 are not limited in this application, and the mounting frame can be used for mounting and carrying the lens barrel 30 and the adjusting structure 50. The lens barrels 30 are arranged side by side on 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 pupil distance, so that the pupil distance can be adjusted by adjusting the distance between the lens barrels 30. The adjusting structures 50 may be used to drive the lens barrels 30, respectively, to achieve adjustment of the pupil distance. Specifically, the handwheel 52 in the adjustment structure 50 may be used to provide an operating position for a user to apply a force to drive rotation. The hand wheel 52 can rotate the threaded rod 51 connected with the hand wheel 52, and the threaded rod 51 and the lens barrel 30 can slide along the axial direction of the threaded rod 51 through the threaded cooperation. Wherein, at least one of the threaded rod 51 and the hand wheel 52 in the adjustment structure 50 may be connected to the mounting frame 10 so as to achieve a support of an overall structure of the adjustment structure 50.
When the pupil distance adjusting mechanism of 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. The end of the threaded rod 51 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, and therefore adjustment of the distance between the lens barrels 30, in other words, adjustment of the interpupillary distance, is achieved. In addition, since the pupil distance adjusting mechanisms in the present embodiment drive the lens barrels 30 through the adjusting structures 50 respectively, in the pupil distance adjusting process, a mode of driving the lens barrels 30 through the adjusting structures 50 to move simultaneously or a mode of driving only one lens barrel 30 through one of the adjusting structures 50 to move can be selected correspondingly according to actual use conditions. Therefore, the pupil distance adjusting mode is diversified, the flexibility of pupil distance adjustment is enhanced, and the convenience of the pupil distance adjusting process is improved.
Further, the adjusting structure 50 in the pupil distance adjusting mechanism in this solution is formed by screwing the threaded rod 51 and the lens barrel 30 to drive the lens barrel 30, and the screw transmission has the advantage of stability and reliability, so as to be beneficial to improving the sliding stability of the lens barrel 30 in the pupil distance adjusting process. 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, the structure for locking the lens barrel 30 after being adjusted in place is not required, thereby being beneficial to simplifying the integral structure of the pupil distance adjusting mechanism, improving the convenience of manufacture and reducing the manufacturing cost. In addition, the threaded rod 51 is driven to rotate by the hand wheel 52, and the hand wheel 52 is driven to rotate by the external force manually applied by a user. Therefore, the user can conveniently control the pupil distance adjusting process, namely, the artificial controllability in the pupil distance adjusting process is improved.
Referring to fig. 2 to 4 in combination, in an embodiment of the invention, the adjusting structure 50 further includes a transmission assembly 53, and an end of the threaded rod 51 away from the lens barrel 30 is connected to the hand wheel 52 through the transmission assembly 53; the hand wheel 52 in the adjusting structure 50 can drive the threaded rod 51 to rotate through the transmission component 53, and the transmission ratio of the transmission component 53 is smaller than 1.
In this embodiment, the transmission ratio of the transmission assembly 53 may be expressed as a ratio of the rotational speed of the handwheel 52 to the rotational speed of the threaded rod 51. Therefore, the transmission ratio is smaller than 1, which means that the rotation speed of the hand wheel 52 is smaller than the rotation speed of the threaded rod 51, so that the hand wheel 52 can accelerate in the process of driving the threaded rod 51 to quickly drive the lens barrel 30 to move to the corresponding position, and the pupil distance adjusting process is completed. Namely, the operation time required by the pupil distance adjusting process is greatly shortened, so that the labor is saved, and the convenience of the pupil distance adjusting process is further improved.

In this embodiment, the transmission process is: when the hand wheel 52 rotates, the driving gear 531 is driven to rotate, the driving gear 531 can drive the driven gear 533 meshed with the driving gear 531 to rotate, and the rotating driven gear 533 can drive the threaded rod 51 connected with the driven gear 533 to rotate. Wherein, the transmission assembly 53 is composed of the driving gear 531 and the driven gear 533, so that the parts of the transmission assembly 53 are relatively small, thereby facilitating the simplification of the structure of the transmission assembly 53 and improving the convenience of assembly. Moreover, the gear transmission has the advantages of stable transmission and compact structure, thereby being beneficial to improving the stability of the hand wheel 52 for driving the threaded rod 51 to rotate and reducing the occupation of the transmission component 53 for space.

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 post 521. Because the inner ring and the outer ring of the bearing 63 are in rolling friction, when a user drives the hand wheel 52 to rotate relative to the supporting seat 61, rolling friction force is generated between the inner ring and the outer ring, and the friction coefficient is relatively small at the moment, so that smoothness of the hand wheel 52 in the rotation adjustment process is improved, and meanwhile, the labor-saving effect can be achieved due to reduction of resistance, so that convenience in the pupil distance adjustment process is improved. The cross section of the insertion post 521 of the hand wheel 52 inserted into the bearing 63 may be non-circular to reduce the possibility of relative rotation. In addition, it should be noted that, in other embodiments, the adjusting mechanism 50 may include only the threaded rod 51 and the hand wheel 52, and at least one of the threaded rod 51 and the hand wheel 52 may be rotatably disposed on the mounting frame 10.

In this embodiment, the threaded rod 51 and the hand wheel 52 are inserted and fixed, so that the assembly process of the threaded rod 51 and the hand wheel 52 is simple, that is, the end of the threaded rod 51 far away from the lens barrel 30 is directly inserted into the hand wheel 52, thereby being beneficial to improving the assembly efficiency. The external surface of the segment inserted into the hand wheel 52 of the threaded rod 51 may not be provided with threads, and the cross section of the segment inserted into the hand wheel 52 may be non-circular, so as to reduce the possibility of rotation of the hand wheel 52 and the threaded rod 51 and improve the stability of the two. Of course, it should be noted that the present application is not limited thereto, and in other embodiments, the threaded rod 51 and the hand wheel 52 may be fixed by magnetic attraction or a snap connection.

The connecting post 31 may be integrally formed with the lens barrel 30, so as to improve the strength of the connecting portion.
Referring to fig. 1, 2, 7 and 8, in an embodiment of the invention, the pupil distance adjusting mechanism further includes a guiding structure 70, and the guiding structure 70 can guide the sliding of the lens barrel 30.
In the present embodiment, the sliding of the lens barrel 30 can be guided by the guide structure 70 so as to be slidable only in a predetermined sliding direction, thereby contributing to an improvement in accuracy of adjustment of the pupil distance. The guide structure 70 may include a guide rod 71, where the guide rod 71 is disposed on the mounting frame 10, and the guide rod 71 extends along a sliding direction of the lens barrel 30 and passes through the lens barrel 30. At this time, since the guide rods 71 pass through the lens barrel 30, the lens barrel 30 is moved only along the extending direction of the guide rods 71 during being driven by the respective adjusting structures 50, thereby realizing the guiding of 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, wherein the two rolling members 73 are rotatably disposed on the lens barrel 30 (i.e. one lens barrel 30 may be provided with one rolling member 73 or two or more rolling members), the mounting frame 10 is provided with a guiding groove 11 at a position corresponding to the two rolling members 73, the guiding groove 11 is opened along the sliding direction of the lens barrel 30, and at least two rolling members 73 are accommodated in the guiding groove 11.

Also, 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 therebetween, thereby contributing to reduction of friction therebetween and improvement of smoothness of sliding of the lens barrel 30. The labor-saving effect can be further achieved, and the convenience of the pupil distance adjusting process is further improved. Wherein, the rolling member 73 may be a roller, please refer to fig. 1 and fig. 2 in combination; of course, the ball may be used, please refer to fig. 7 and 8 in combination.

In the present embodiment, the rolling member 73 is provided at the lower end of the lens barrel 30 so that the lens barrel 30 can be supported mainly by the rolling member 73. At this time, the pressure applied to the mounting frame 10 by the lens barrel 30 is maximized at this point, and rolling friction with the lens barrel 30 is achieved at this point, so that it is advantageous to greatly improve the smoothness of movement of the lens barrel 30 and reduce wear caused during movement. Of course, it should be noted that, in other embodiments, the guide rod 71 and the rolling member 73 may be disposed at the upper and lower ends of the lens barrel 30, that is, the rolling member 73 is disposed at the upper end of the lens barrel 30, and the guide rod 71 is disposed at the upper end of the lens barrel 30. In addition, the guide structure 70 includes only the guide rod 71, and the guide rod 71 may be provided at least one of the upper and lower ends of the lens barrel 30.
