Description

Technical Field

[0001] The utility model belongs to the field of low-light level and digital night vision, and in particular relates to a comprehensive hanging bracket for head-mounted night vision devices. Background Art

[0002] Head-mounted night vision goggles are a common type of night sight, and they can be divided into low-light-level night vision goggles and digital night vision goggles. These goggles come in two types: monocular and binocular. There are also various helmet-mounted mounts for these types, but these are simple, non-focusing mounts suitable only for monocular night vision goggles. However, binocular night vision goggles lack a focusing function, making it difficult to achieve coaxial alignment between the two eyes. Therefore, we propose a comprehensive mount that can support both low-light-level night vision goggles and digital night vision goggles, as well as both monocular and binocular night vision goggles. Utility Model Content

[0030] A head-mounted night vision device integrated bracket, such as Figures 1 to 12 As shown, it includes a main pylon 1 and two auxiliary pylons 2 rotatably connected to both ends of the main pylon 1;

[0031] The auxiliary bracket 2 includes an adjustment seat 3, an adjustment screw A4, and an adjustment screw B5. A horseshoe nut 6 is fixed to the lower part of the adjustment seat 3 by screws; a first mounting hole 7 is provided at the front end of the adjustment seat 3, and two support seats 8 are provided at the rear end of the adjustment seat 3. A second mounting hole 9 is provided on the support seat 8.

[0032] The threaded end of the adjusting screw B5 passes through the first mounting hole 7 from top to bottom, and the threaded end of the adjusting screw B5 is connected to the upper and lower inclination adjustment hand wheels 10 through threads;

[0033] The other end of the adjusting screw B passes through the third mounting hole 11 provided at the front end of the slide 26 and is fixed in the third mounting hole 11 by a pin 12;

[0034] A fourth mounting hole 13 and a fifth mounting hole 14 are provided at the rear end of the slide 26 , and the fourth mounting hole 13 and the fifth mounting hole 14 intersect vertically;

[0035] A stud 15 is provided in the fourth mounting hole 14, and a first screw hole 16 is radially provided on the stud 15.

[0036] The adjusting screw A4 passes through the second mounting hole 9, the fourth mounting hole 13 and the first screw hole 16 and is threadedly connected to the stud 15; a horizontal inner and outer angle adjustment hand wheel 17 is threadedly connected to the end of the adjusting screw A4;

[0037] A dovetail groove 18 is also provided on the slide 26, a base 19 is provided in the dovetail groove 18, and a second screw hole 20 is provided at the lower part of the base 19; baffles A21 and baffles B22 are provided at both ends of the dovetail groove 18, and baffles A21 and baffles B22 are fixed to the slide 26 by screws.

[0038] A hole 23 is formed on the baffle A21 and the baffle B22. The screw end of the left and right pupil distance adjustment hand wheel 24 passes through the hole 23 and is threadedly connected to the second screw hole 20 provided at the lower part of the base 19.

[0039] A third screw hole (not shown in the figure) is provided at the end of the adjusting screw A4, and the horizontal inner and outer angle adjusting hand wheel 17 and the adjusting screw A4 are fixed together through screws and the third screw hole.

[0040] An elastic component 25 is provided between the slide seat 26 and the adjustment seat 3 , and the elastic component 25 is a spring.

[0041] The utility model is used as follows: the night vision device 27 is connected to the auxiliary bracket 2, and the main bracket 1 is connected to the helmet.

[0042] When the pupil distance needs to be adjusted, the pupil distance adjustment handwheel 24 of the left and right eyes can be rotated forward or reverse respectively, so that the rotation of the screw drives the horseshoe nut 6 to move horizontally in the X-axis direction through the slide 26, so that the two horseshoe nut 6 can be moved closer to or away from each other, thereby achieving the function of pupil distance adjustment.

[0043] When imaging requires adjustment of the upper and lower optical axes, because the horseshoe nut 6 is connected to the slide 26 in the form of a rotating shaft through the horizontal inner and outer angle adjustment hand wheel 17, that is, the horseshoe nut 6 can be axially rotated in the Z-axis direction around the slide 26, and the rotation amount at this time can be controlled by the upper and lower inclination angle adjustment hand wheel 10 (rotating the upper and lower inclination angle adjustment hand wheel 10, the upper and lower inclination angle adjustment hand wheel 10 is caused to move axially upward or downward through the thread, driving the front end of the adjustment seat 3 to move upward or downward. Since the adjustment seat 3 is fixed in the fourth mounting hole 13 at the rear end of the slide 26 by the adjusting screw A4, the upward or downward movement of the front end of the adjustment seat 3 will cause the adjustment seat 3 to produce an angular deflection with the adjusting screw A4 as the rotation axis, thereby driving the horseshoe nut 6 fixed on the adjustment seat 3 to have an angular deflection).

[0044] Specifically, the vertical tilt adjustment wheel 10 passes through the horseshoe nut 6 and is threadedly mounted on the adjustment base 3. To adjust the vertical optical axis, simply rotate the vertical tilt adjustment wheel 10. The adjustment screw B then rotates the horseshoe nut 6 up and down around the Z-axis, thereby adjusting the optical axis. This adjustment method can be used when the left and right optical axes need to be aligned (meaning that the axes of the incident light on the left and right products are relatively parallel in space).

[0045] When imaging requires adjustment of the inclination (the angle between the projections of the incident light beams of the left and right night vision devices on the horizontal plane), the horseshoe nut 6 is fixed to the adjustment base 3, which is connected to the slide 26 via the vertical inclination adjustment handwheel 10 in the form of a rotating shaft. This means that the horseshoe nut 6 can rotate axially in the Y direction around the slide 26. The amount of rotation is controlled by the horizontal inclination adjustment handwheel 17, which is threadedly mounted on the adjustment screw A4. When inclination adjustment is required, simply rotate the horizontal inclination adjustment handwheel 17, which drives the horseshoe nut 6 to rotate left and right around the adjustment screw B5 in the Y direction via the adjustment screw A4, thereby achieving the purpose of adjusting the inclination and outclination of the optical axis. This method can be used when the optical axis needs to be aligned (the projections of the incident light beams of the left and right devices on the horizontal plane are relatively parallel).

[0046] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
