Description

Technical Field

[0001] The invention relates to the technical field of night vision goggles brackets, and in particular to a multi-directionally adjustable night vision goggles bracket. Background Art

[0002] Night vision goggles are night sights with image intensifiers as their core components. When working, they do not use infrared searchlights to illuminate the target, but use the light reflected by the target under weak light to be enhanced by the image intensifier on the fluorescent screen to form a visible image that can be perceived by the human eye to observe and aim at the target. In the prior art, night vision goggles are usually installed on helmets using night vision goggles brackets when in use. The existing brackets have the following technical problems:

[0003] 1. The night vision goggles can be flipped up to the top of the helmet or flipped down to the eyes through the existing bracket, but the existing bracket has no locking structure, which can easily cause the night vision goggles to accidentally flip down and hit the user.

[0004] 2. There are tolerances in the dovetail joints of night vision devices from different manufacturers and models. At the same time, there are inevitable errors in the dovetail groove of the bracket during the production process, which makes it difficult for the dovetail groove of the same bracket to be perfectly compatible with multiple night vision devices with similar dovetail joints.

[0005] 3. Although the existing bracket can adjust the parallel angle between the night vision goggles and the eyes, it cannot adjust the height of the night vision goggles, which makes it impossible for the user to effectively make the eyes parallel to the eyepiece of the night vision goggles.

[0006] 4. Not all individual low-light night vision goggles use the same dovetail connector, which means that night vision goggles using other dovetail connectors can only use brackets with specific dovetail grooves, resulting in the inability to quickly match multiple night vision goggles with the same existing bracket; when a user switches from one model of night vision goggles to another, it means that the user needs to purchase a new bracket for the new night vision goggles.

[0007] 5. Different helmets and night vision goggles often have different tolerances or completely different buckle parts. The existing bracket and helmet connection cannot be quickly disassembled, which makes the existing night vision goggles bracket may not be effectively used on a specific helmet.

[0063] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0064] like Figure 1-20As shown, this embodiment provides a multi-directionally adjustable night vision goggle bracket, including a helmet connecting portion 10 for connecting to a helmet, a night vision goggle connecting portion 20 for installing a night vision goggle, and a flip connecting portion 30 arranged between the helmet connecting portion 10 and the night vision goggle connecting portion 20.

[0065] The flip connection part 30 includes a housing 31, a flip shaft 32, a flip frame 33 and a flip locking mechanism 34. The housing 31 is connected to the helmet connection part 10. The shaft body of the flip shaft 32 is arranged in the housing 31 in a transverse direction (referring to the left and right direction) and the shaft end extends out of the housing 31; the flip shaft 32 is rotatably arranged with the housing 31, such as being connected by a bearing. The distal end of the flip frame 33 is connected to the night vision device connection part 20, and the proximal end is connected to the end of the flip shaft 32.

[0066] The flip locking mechanism 34 includes a limiting sleeve 341 , a fixing sleeve 342 , an unlocking push rod 343 , a flip unlocking button 344 and a locking block 345 . The limiting sleeve 341 is fixedly sleeved on the flip shaft 32, and the limiting sleeve 341 is provided with a locking groove 3411 and an unlocking groove 3412. The locking groove 3411 is connected with the unlocking groove 3412 in the axial direction of the flip shaft 32, thereby ensuring that the locking block 345 can enter the unlocking groove 3412 from the locking groove 3411 and can enter the locking groove 3411 from the unlocking groove 3412; illustratively, the unlocking groove 3412 is an annular groove, which is convenient for processing and does not need to consider the stroke problem of the unlocking groove 3412; the groove depth of the unlocking groove 3412 is greater than the groove depth of the locking groove 3411, thereby ensuring that the locking block 345 can be limited in the locking groove 3411 and the locking block 345 can be unlocked in the unlocking groove 3412; in this embodiment, the locking groove 3411 is closer to the flip unlocking button 344 than the unlocking groove 3412. The fixed sleeve is transversely fixed in the housing 31, generally fixed by a set screw or bolt, etc.; the fixed sleeve is provided with a transverse through-shaft hole, in which the unlocking push rod 343 is slidably arranged; a limit block 3421 is provided at the inner end of the fixed sleeve (referring to the end away from the flip unlocking button 344), and the limit block 3421 is used to limit the locking block 345 so that the locking block 345 cannot rotate around the unlocking push rod 343 to avoid the locking function failure; alternatively, the unlocking push rod 343 and the through-shaft hole are circumferentially limited by a guide key (the unlocking push rod 343 can still slide axially), so there is no need to provide a limit block 3421 to prevent the locking block 345 from rotating around the unlocking push rod 343. The flip unlocking button 344 is arranged outside the housing 31 and fixed to the outer end of the unlocking push rod 343. The locking block 345 is fixed to the inner end of the unlocking push rod 343, one side of the locking block 345 is against the limit block 3421, and one end of the locking block 345 is in the locking groove 3411 or the unlocking groove 3412; the locking block 345 is adapted to the shape of the locking groove 3411, and preferably, the cross-section of the end of the locking groove 3411 close to the unlocking groove 3412 is larger than the cross-section of the end of the locking groove 3411 away from the unlocking groove 3412, so that the locking block 345 has a guiding effect in the process of retreating to the locking groove 3411, and the retreat action is smoother.

[0067] The fixed shaft sleeve 342 is relatively fixed to the shell 31. When the locking block 345 is in the locking groove 3411, the shell 31 cannot rotate or swing relative to the flip shaft 32, so that the flip frame 33 cannot flip down, so that the night vision goggles installed on the night vision goggles connecting part 20 remain in the state of being on the helmet; when it is necessary to flip down, press the flip unlocking button 344, and the locking block 345 is moved from the locking groove 3411 to the unlocking groove 3412 through the unlocking push rod 343. At this time, the unlocking is completed, and the fixed shaft sleeve 342 (regarded as a whole with the shell 31) can rotate or swing relative to the axis of the flip shaft 32, so that the flip frame 33 can flip down; in this way, it is in a locked state when flipped up, and it needs to be pressed to unlock when flipping down, so as to avoid the problem of the night vision goggles accidentally flipping down and bumping the user due to strong collisions during combat.

[0068] It should be noted that the flip frame 33 and the flip axis 32 are divided into a rotational connection and a non-rotational connection; when the rotational connection is used, a fine-tuning plate 351 fixedly connected to the flip axis 32 needs to be provided, and the flip frame 33 and the fine-tuning plate 351 can be swung and connected within a certain angle, and the contents of the fine-tuning plate 351 refer to the subsequent embodiments; the non-rotational connection means that the flip axis 32 and the flip frame 33 are relatively fixed; only in this way can the above-mentioned function of "locking in the upward state and pressing to unlock when flipping down" be realized.

[0069] In one embodiment, a flip spring installation cavity is provided at one end of the fixed sleeve 342 away from the limit block 3421; the flip locking mechanism 34 also includes a flip locking spring, which is installed in the flip spring installation cavity and is used to provide a thrust for the unlocking push rod 343 to move out of the housing 31. In this way, under the action of the flip locking spring, the unlocking push rod 343 has a tendency to move out of the housing 31, so that the locking block 345 in the locking groove 3411 will not slide into the unlocking groove 3412, avoiding unlocking without external force; at the same time, the locking block 345 in the unlocking groove 3412 has a tendency to slide into the locking groove 3411 along the axial direction of the flip shaft 32, realizing the function of "automatically locking after flipping up to the right position".

[0070] In one embodiment, an ear plate 331 and a pivot protrusion 332 are provided at one end of the flip frame 33 close to the shell 31, the ear plate 331 is located on the side of the shell 31 away from the flip unlocking button 344, and the pivot protrusion 332 is located on the other side of the shell 31, and the flip frame 33 is rotatably connected to the flip shaft 32 through the ear plate 331 and the pivot protrusion 332.

[0071] The flip connection part 30 further includes an angle fine-tuning mechanism 35, and the angle fine-tuning mechanism 35 includes a fine-tuning plate 351 and a fine-tuning knob 352. The fine-tuning plate 351 is arranged on the side of the ear plate 331 away from the housing 31, and the fine-tuning plate 351 is fixed to the end of the flip shaft 32. The fine-tuning knob 352 includes a button ear 3521, a limiting plate 3522 fixed on the button ear 3521, a rotating movable plate 3523 fixed at the center of the limiting plate 3522, and an eccentric shaft 3524 eccentrically arranged on the rotating movable plate 3523. The fine-tuning plate 351 is provided with an angle fine-tuning flat hole 3511, the ear plate 331 is provided with an angle fine-tuning dial hole 3311 matched with the eccentric shaft 3524, the rotating movable disk 3523 is gap installed in the angle fine-tuning flat hole 3511, the eccentric shaft 3524 is passed through the angle fine-tuning dial hole 3311, and a nut is screwed on the end of the eccentric shaft 3524, and the ear plate 331 and the fine-tuning plate 351 are clamped between the nut and the limit plate 3522.

[0072] When the button ear 3521 of the fine-tuning knob 352 is rotated, the eccentric shaft 3524 interacts with the angle fine-tuning toggle hole 3311. Since the fine-tuning plate 351 is fixedly connected to the flip shaft 32, the ear plate 331 swings around the flip shaft 32 at a certain angle, thereby adjusting the parallelism between the night vision device and the eye. This process is to adjust the angle of the flip frame 33, and has nothing to do with the angle reversal angle of the flipping up and down of the flip frame 33. Among them, the angle fine-tuning flat hole 3511 is a waist-shaped through hole. When the angle is fine-tuned, the rotating movable plate 3523 can not only rotate in the angle fine-tuning flat hole 3511, but also slide along the angle fine-tuning flat hole 3511, thereby avoiding physical interference.

[0073] In one embodiment, the shell 31 and the fine-tuning plate 351 are both provided with a matching limiting lug 312. When the locking block 345 is in the locking groove 3411, the two limiting lugs 312 are separately provided. When the flip frame 33 is flipped down, the two limiting lugs 312 abut against each other, thereby avoiding excessive flipping down and injuring the user's eyes.

[0074] In one embodiment, the helmet connection part 10 includes a plug-in slider 11, which is slidably connected to the shell 31, and a vertical screw mounting groove 111 is provided on the side of the plug-in slider 11 facing the shell 31, and a horizontal push button mounting groove 311 is provided on the side of the shell 31 facing the plug-in slider 11, and a height adjustment mechanism 40 is provided between the plug-in slider 11 and the shell 31.

[0075] The height adjustment mechanism 40 includes a height adjustment screw 41, a height adjustment push button 42, a height adjustment locking block 43 and a height adjustment reset spring 44. The height adjustment screw 41 is fixed vertically in the screw mounting groove 111; illustratively, the upper and lower side walls of the screw mounting groove 111 are respectively provided with threaded holes, one of which is a threaded through hole, and the height adjustment screw 41 is screwed into the screw mounting groove 111 from the threaded through hole, and further screwed into the other threaded hole, thereby completing the fixing of the height adjustment screw 41. A part of the height adjustment push button 42 is exposed outside the housing 31, and the other part is slidably arranged in the push button mounting groove 311; it should be noted that the height adjustment push button 42 slides horizontally. The height adjustment locking block 43 is connected to the height adjustment push button 42.

The height adjustment reset spring 44 is transversely arranged in the push button installation groove 311, and is used to provide a transverse thrust for the height adjustment push button 42 to slide out of the housing 31. In this embodiment, the height adjustment locking block 43 is located on the side of the height adjustment screw 41 away from the height adjustment locking block, and the height adjustment reset spring 44 and the height adjustment locking block 43 are on the same side of the height adjustment screw 41; illustratively, a spring cavity is provided at the inner end of the height adjustment push button 42, one end of the height adjustment reset spring 44 is located in the spring cavity, and the other end is against the side wall of the push button mounting groove 311.

[0076] Under normal conditions, under the action of the height adjustment reset spring 44, the height adjustment push button 42 is in a state with the longest exposed length. At this time, the internal thread of the threaded surface 431 of the height adjustment locking block 43 is meshed with the external thread of the height adjustment screw 41, so that the plug-in slider 11 cannot slide relative to the housing 31, that is, the plug-in slider 11 and the housing 31 are in a locked state and the height cannot be adjusted; the height adjustment push button 42 is pressed inward, the height adjustment reset spring 44 is compressed to store energy, and the height adjustment locking block 43 leaves the height adjustment screw 41 and releases the lock. At this time, the housing 31 can be slid freely to adjust the height; after the height is suitable, the height adjustment push button 42 is released, and under the action of the height adjustment reset spring 44, the height adjustment locking block 43 is locked with the height adjustment screw 41 again to keep the current height unchanged. In this way, the height of the night vision device can be adjusted very conveniently.

[0077] In one embodiment, the helmet connecting portion 10 includes a helmet socket 12 and a buckle unlocking mechanism 13 .

[0078] The helmet holder 12 is provided with a longitudinal lock tongue installation cavity 121 and a transverse fin plate installation cavity 122, wherein the lock tongue installation cavity 121 is vertically arranged and connected to the fin plate installation cavity 122. The helmet holder 12 is used for quick connection with a card slot on a helmet.

[0079] The buckle unlocking mechanism 13 includes a push block 131, a linkage lock tongue 132, an unlocking fin plate 133 and a locking return spring 134. The push block 131 is slidably arranged in the lock tongue installation cavity 121, and a lock tongue slide groove is arranged on one side of the push block 131, and a guide extrusion surface 1311 is arranged at one end of the push block 131 facing the unlocking fin plate 133. The front end of the linkage lock tongue 132 (i.e., the lock tongue 1321) extends out of the helmet holder 12, and the lock tongue 1321 is provided with an arc chamfer; the middle section of the linkage lock tongue 132 is slidably installed in the lock tongue slide groove; the rear end of the linkage lock tongue 132 is provided with a stopper 1322 that abuts against the rear end of the push block 131. The middle section of the unlocking fin plate 133 is slidably mounted in the fin plate mounting cavity 122, and both ends are exposed from the helmet holder 12. The position of the unlocking fin plate 133 facing the push block 131 is provided with a V-shaped groove 1331 adapted to the guide extrusion surface 1311. The unlocking reset spring is arranged in the lock tongue mounting cavity 121, and is used to provide a thrust for the linkage lock tongue 132 to slide out of the helmet holder 12; illustratively, one end of the unlocking reset spring abuts against the inner wall of the lock tongue mounting cavity 121, and the other end abuts against the stopper 1322.

[0080] During quick connection, the structure on one side of the helmet socket 12 (referring to the side away from the locking tongue 1321) is inserted into the corresponding structure of the helmet slot, and then the side of the helmet socket 12 with the locking tongue 1321 is pressed. Under the action of the helmet slot and the arc chamfer, the locking tongue 132 shrinks inward, and the locking reset spring 134 is compressed. When the locking tongue 1321 is aligned with the corresponding structure of the helmet slot (such as the locking slot), the locking tongue 132 extends outward under the action of the locking reset spring 134, and the locking tongue 1321 is inserted into the locking slot, completing the quick connection between the night vision device bracket and the helmet. When disassembling, push any one end of the unlocking fin plate 133 to make it move laterally. During this process, the groove wall of the V-shaped groove 1331 of the unlocking fin plate 133 interacts with the guide extrusion surface 1311 of the push block 131, so that the push block 131 slides inward, and then under the action of the stop block 1322, the linkage lock tongue 132 slides inward, so that the lock tongue 1321 withdraws from the lock groove, completing the unlocking. At this time, the night vision device bracket can be removed from the helmet.

[0081] In one embodiment, the helmet mount 12 is provided with multiple pairs of through holes 123, and the plug-in slider 11 is provided with multiple pairs of height adjustment threaded holes 112, and the multiple pairs of through holes and the multiple pairs of height adjustment threaded holes 112 are evenly spaced along the height direction, and the number of pairs of height adjustment threaded holes 112 is greater than the number of pairs of through holes, and the helmet mount 12 is connected to the plug-in slider 11 by bolts, and the plug-in slider 11 is connected to the shell 31.

[0082] By selecting different height adjustment threaded holes 112 , the plug-in slider 11 can be placed at different heights of the helmet holder 12 , thereby further adjusting the height of the night vision device.

[0083] In one embodiment, the night vision device connection part 20 includes an instrument holder 21, and the instrument holder 21 is slidably connected to the flip frame 33. A button mounting groove 211 is provided on one side of the instrument holder 21 for mounting a position adjustment button 51; a mounting lug 212 is provided on each side of the notch of the button mounting groove 211 for mounting a rotating shaft, and connected to the position adjustment button 51 through the rotating shaft. A row of position locking grooves 333 are provided on one side of the flip frame 33 corresponding to the button mounting groove 211; illustratively, the locking grooves are racks or semicircular arc grooves distributed at equal intervals. A position adjustment locking mechanism 50 is provided between the instrument holder 21 and the flip frame 33;

[0084] The position adjustment locking mechanism 50 includes a position adjustment button 51, a position locking protrusion 52 and a position adjustment locking spring 53. A portion of the position adjustment button 51 is located in the button mounting slot 211; the other portion is located outside the button mounting slot 211; the middle portion of the position adjustment button 51 is rotatably connected to the instrument holder 21, for example, the middle portion of the position adjustment button 51 is rotatably connected to a rotating shaft installed on the mounting protrusion 212. The position locking protrusion 52 is installed on the side of the position adjustment button 51 facing the position locking slot 333; preferably, the shape of the position locking protrusion 52 is adapted to the locking slot. The position adjustment locking spring 53 is arranged in the button mounting groove 211, and the position adjustment locking spring 53 is used to provide a thrust for the portion of the position adjustment button 51 located in the button mounting groove 211 so that the position locking protrusion 52 can be inserted into the position locking groove 333; exemplarily, a spring cavity is provided at the position where the position adjustment button 51 and the position adjustment locking spring 53 act, one end of the position adjustment locking spring 53 is located in the spring cavity, and the other end is against the wall panel of the button mounting groove 211.

[0085] Under normal conditions, under the action of the position adjustment locking spring 53, the position locking protrusion 52 is in a certain position locking groove 333, and the instrument holder 21 cannot slide along the flip frame 33; after pressing the position adjustment button 51, the position locking protrusion 52 is disengaged from the position locking groove 333, and the unlocking is completed. At the same time, the position adjustment locking spring 53 is compressed to store energy, and the instrument holder 21 can slide along the flip frame 33 in a certain area; after sliding to a suitable position, the position adjustment button 51 is released, and under the action of the position adjustment locking spring 53, the position locking protrusion 52 is re-engaged in the position locking groove 333, and the locking is completed. At this time, the instrument holder 21 cannot slide along the flip frame 33. In this way, the distance between the night vision device and the eye can be quickly adjusted.

[0086] In one embodiment, the night vision device connection part 20 includes an instrument holder 21, and the instrument holder 21 includes a holder bottom plate 213 and a dovetail groove side plate 214 and a dovetail groove movable side plate 215 arranged on the holder bottom plate 213. The holder bottom plate 213 is connected to the flip frame 33, and the dovetail groove side plate 214 and the dovetail groove movable side plate 215 are spaced apart and a trapezoidal dovetail groove 216 for installing the night vision device is formed therebetween.

[0087] The dovetail groove movable side plate 215 is slidably set on the base bottom plate 213 along the length direction of the trapezoidal dovetail groove 216, and a gasket mounting recessed groove 2151 is set on the side surface of the dovetail groove movable side plate 215 facing away from the base bottom plate 213, and a strip hole 2153 is set in the gasket mounting recessed groove 2151. The length direction of the strip hole 2153 is consistent with the sliding direction of the dovetail groove movable side plate 215, and a threaded hole is set at the position of the base bottom plate 213 corresponding to the strip hole 2153. The dovetail groove movable side plate 215 and the base bottom plate 213 are detachably connected by bolts that penetrate the strip hole 2153 and screw into the threaded hole. Optionally, a strip gasket 2153 is provided in the gasket installation groove 2151, and the strip gasket 2153 is provided with a circular hole corresponding to the threaded hole, and the bolt passes through the circular hole of the strip gasket 2153 and the strip hole 2153 of the gasket installation groove 2151 and is screwed and fixed with the threaded hole of the base bottom plate 213. Optionally, the sliding direction between the dovetail groove movable side plate 215 and the base bottom plate 213 is limited by a guide block and a guide groove; or the sliding direction between the dovetail groove movable side plate 215 and the base bottom plate 213 is limited by a guide shaft and a guide hole; or a combination of the above two methods is used to limit the sliding direction.

[0088] Loosen the bolts and slide the dovetail groove movable side plate 215. Since there is a trapezoidal dovetail groove 216 between the dovetail groove side plate 214 and the dovetail groove movable side plate 215, the width of the trapezoidal dovetail groove 216 changes after the dovetail groove movable side plate 215 slides along the length direction of the trapezoidal dovetail groove 216, thereby eliminating or reducing the influence of tolerance and processing errors, so that the night vision goggles bracket can be installed with a variety of night vision goggles, improving compatibility.

[0089] In one embodiment, the night vision device connection part 20 includes an instrument holder 21, an insert strip 22, and an instrument clamping thrust spring 23. The instrument holder 21 is connected to the flip frame 33, and a trapezoidal dovetail groove 216 is provided on the side of the instrument holder 21 away from the flip frame 33, and a slot 217 extending along the length direction of the trapezoidal dovetail groove 216 is provided at one end of the instrument holder 21, and a connecting cavity 218 is provided between an inward section of the slot 217 and the trapezoidal dovetail groove 216. One end of the inserting strip 22 is inserted into the slot 217, and the inserting strip 22 is rotatably connected to the side wall of the slot 217, and is connected via a rotating shaft; the inner end of the inserting strip 22 is provided with a protruding clip 221 that matches the clip slot of the dovetail plug-in part of the night vision device on the side facing the trapezoidal dovetail slot 216, wherein the protruding clip 221 is provided with a guide surface on the side facing the large end of the trapezoidal dovetail slot 216, and the other end of the inserting strip 22 is located outside the instrument holder 21. The instrument clip thrust spring 23 is provided in the slot 217, and is used to provide thrust for the inserting strip 22 so that the protruding clip 221 is clipped into the clip slot of the dovetail plug-in part of the night vision device.

[0090] When installing the night vision device, align the dovetail plug-in part of the night vision device with the trapezoidal dovetail groove 216 of the bracket. In the process of pushing the night vision device inward, the solid part of the dovetail plug-in part acts on the guide surface of the protruding clip 221, so that the insertion strip 22 swings around the rotating shaft. When the clip groove of the dovetail plug-in part is aligned with the protruding clip 221, under the action of the instrument clip thrust spring 23, the insertion strip 22 is reset, and the protruding clip 221 is clipped into the clip groove. At this time, the night vision device is installed and cannot be removed; by pressing the outer end of the insertion strip 22, the protruding clip 221 will be out of the clip groove, and the night vision device can be removed at this time. It can be seen that the plug board of this embodiment is similar to a lever with a reset function.

[0091] Since not all individual low-light-level night vision goggles are connected to the bracket using the same dovetail groove, night vision goggles with different dovetail grooves can only use brackets with specific dovetail grooves, which makes it impossible for the existing same bracket to quickly match multiple night vision goggles; when a user switches from one model of night vision goggles to another, it means that the user needs to buy a new bracket for the dovetail groove of the new night vision goggles, which wastes costs. The multi-directionally adjustable night vision goggles bracket provided in this embodiment adopts a modular design, which can quickly disassemble the night vision goggles connection part and replace it with a night vision goggles connection part that matches the corresponding dovetail groove or other buckle structure, so that the same bracket can be quickly modified and matched with different types of night vision goggles.
