Technical Field

[0001] This application relates to the field of night vision technology, and in particular to a night vision adapter bracket. Background Technology

[0002] Night vision devices are emerging and gaining increasing attention in defense, industry, civilian, and hunting fields. Ultimately, night vision devices need to be attached to a helmet, usually through various helmet mounts, to help the user achieve a comfortable viewing position, enabling the human eye to observe and identify targets and meet application requirements.

[0003] Currently, the helmet mounts on dump trucks on the market have relatively simple structures. Conventional dump truck mounts can only be adjusted forward and backward and up and down, but cannot be adjusted left and right or tilt. Therefore, they are still somewhat lacking in terms of adjustment versatility and user comfort. Summary of the Invention

[0004] Based on this, in order to solve the above-mentioned technical problems, this application provides a night vision device adapter bracket, which can realize the adjustment of the night vision device in front and behind, up and down, left and right, and tilt.

The night vision adapter bracket of this application employs a reinforced structural design and incorporates high-strength engineering plastic materials, enabling the bracket itself to achieve multi-functional adjustments while meeting the requirements of low weight and high ergonomics.

[0046] Please see Figure 1 This is a usage diagram of a night vision adapter bracket 100 according to an embodiment of this application, wherein the night vision adapter bracket 100 is used to connect the night vision device 200 and the helmet 300. Specifically, the night vision device 200 is mounted on one end of the night vision adapter bracket 100, and the other end is connected to the helmet 300. Through the night vision adapter bracket 100, the night vision device 200 can be flipped and switched between a drooping state and an up-and-down state. The night vision device 100 can be adjusted left and right in the X direction, forward and backward in the Y direction, and up and down in the Z direction relative to the helmet 300, and can be adjusted in pitch around an axis parallel to the X direction.

[0047] Please refer to the following: Figure 2 and Figure 3The working state of the night vision adapter bracket 100 is shown in the figure. It includes a night vision device connector 10, a flip assembly 20, a pitch adjustment assembly 30, a front and rear adjustment frame 40, a front and rear adjustment assembly 50, a translation adjustment seat 60, a translation adjustment assembly 70, and a helmet mounting base 80. The night vision device connector 10 is used to connect to the cable tray interface on the night vision device 200, thereby connecting the night vision device 200. The flip assembly 20 is installed on the night vision device connector 10 and can drive the night vision device connector 10 to flip, thus switching the night vision device 200 connected to the night vision device connector 10 between a drooping state and an upward state. The pitch adjustment assembly 30 is located between the flip assembly 20 and the front and rear adjustment frame 40, and can adjust the rotation of the flip assembly 20 relative to the front and rear adjustment frame 40 around an axis parallel to the left and right direction to adjust the pitch. The tilt angle of the entire flip assembly 20 and the night vision device connector 10 connected to the flip assembly 20, and the night vision device 200 relative to the front and rear adjustment frame 40; the front and rear adjustment frame 40 is mounted on the front and rear adjustment assembly 50 and can be adjusted in the Y direction by the front and rear adjustment assembly 50; the front and rear adjustment assembly 50 is connected to the translation adjustment seat 60, and the translation adjustment seat 60 is mounted to the helmet mount 80 by the translation adjustment assembly 70, and the position of the translation adjustment seat 60 relative to the helmet mount 80 in the X and Z directions can be adjusted by the translation adjustment assembly 70.

[0048] Please refer to the following: Figure 4 The night vision device connector 10 includes a night vision device connector body 11 and a release buckle 12, a release buckle return spring 13, and a release buckle pivot pin 14 mounted on the night vision device connector body 11. A release buckle mounting hole 111 is provided at the lower part of the night vision device connector body 11, and the release buckle 12 is mounted at the release buckle mounting hole 111 via the release buckle pivot pin 14. A flip-up flat shaft mounting hole 112 is provided at the upper part of the night vision device connector body 11, the axis of which is parallel to the X-direction, for connecting the flip assembly 20. The release buckle 12 includes a release buckle pressing part 121, a spring mounting hole 122, and a pivot pin mounting hole 123. The release buckle return spring 13 is mounted in the spring mounting hole 122 and abuts against the flip assembly 20. The release latch pressing part 121 and the spring mounting hole 122 are located on both sides of the pivot pin mounting hole 123. Pressing the release latch pressing part 121 generates a force that compresses the release latch reset spring 13 towards the flip assembly 20, and resets the release latch 12 when the external force on the release latch pressing part 121 is released. When connecting to or disconnecting from the cable tray interface of the night vision device 200, pressing the release latch 12 retracts the locking tongue, allowing connection or disconnection, and then releasing the release latch 12 to reset.

[0049] Please refer to the following: Figure 5The flip assembly 20 includes a flip frame 21, a flip flat shaft 22, a flip spring 23, a pitch adjustment pin 24, a flip shaft cylindrical pin 25, and a spring fixing pin 26. The flip flat shaft 22 is installed in the flip flat shaft mounting hole 112 of the night vision device connector 11 via the pitch adjustment pin 24 and fixed by the flip shaft cylindrical pin 25, thus fixing the flip flat shaft 22 to the night vision device connector 11. The flip frame 21 is also fitted onto the pitch adjustment pin 24, allowing the flip flat shaft 22 to rotate relative to the flip frame 21 around the pitch adjustment pin 24. One end of the flip spring 23 is fixed to the flip frame 21 by the spring fixing pin 26, and the other end elastically abuts against the flip flat shaft 22. The elastic force provided by the flip spring 23 fixes the angle of the flip flat shaft 22, allowing the flip flat shaft 22 to flip against the elastic force of the flip spring 23. More specifically, the tilting frame 21 has a pin connection hole 211, and the tilting flat shaft 22 has a pin hole 222. The axial directions of the pin connection hole 211 and the pin hole 222 are both parallel to the X direction. The pitch adjustment pin 24 passes through the tilting flat shaft mounting hole 112, the pin hole 222, and the pin connection hole 211 to connect the night vision device mounting base 11, the tilting flat shaft 22, and the tilting frame 21. The tilting frame 21 has a fork 212 on the side away from the pitch adjustment pin 24 for connecting with the pitch adjustment assembly 30. One end of the tilting spring 23 extends out from one side of the pitch adjustment pin 24 with a spring tongue 231, and the other end of the tilting spring 23 is fixed to the tilting frame 21 by a spring fixing pin 26 installed on the spring fixing hole 232, so that the spring tongue 231 can elastically extend towards the pitch adjustment pin 24. The flip-out flat shaft 22 forms spring contact surfaces 221 on both sides of the pin hole 222 (i.e., the pitch adjustment pin 24). The spring tongue 231 selectively abuts against one of the spring contact surfaces 221 on both sides. When one spring contact surface 221 abuts against the spring tongue 231, the night vision device connector 10 is located below the pitch adjustment pin 24, which allows the night vision device 200 connected to the night vision device connector 10 to be in a drooping state. When the other contact surface 221 abuts against the spring tongue 231, the night vision device connector 10 is located above the pitch adjustment pin 24, which allows the night vision device 200 connected to the night vision device connector 10 to be in an upward flipping state.

[0050] The pitch adjustment assembly 30 is mounted on the front and rear adjustment frame 40 and includes a pitch adjustment knob 31, a transmission screw 32, a toggle block 33, a toggle block limiting screw 34, and a knob connecting screw 35, all coaxially arranged along the Z direction. The pitch adjustment knob 31 is fixed to one end of the transmission screw 32 via the knob connecting screw 35. The transmission screw 32 is coaxially arranged with the adjustment knob 31 along the Z direction. The toggle block 33 is threaded onto the screw rod of the transmission screw 32, and the toggle block limiting screw 34 is connected to the other end of the transmission screw 32. Protrusions 331 extend from both sides of the toggle block 33 along an axis parallel to the X direction. The protrusions 331 are embedded in the forks 212 on the tilting frame 21. The other end of the transmission screw 32 is screwed into the screw hole 332 on the toggle block 33 along a direction parallel to the Z direction. Thus, when the pitch adjustment knob 31 is rotated, the transmission screw 32 rotates accordingly, and the toggle block 33 moves up and down along the transmission screw 32 as the transmission screw 32 rotates. The protrusion 331 embedded in the fork 212 drives the tilting frame 21 to swing up and down around the pitch adjustment pin 24, thereby realizing pitch adjustment by rotating around an axis parallel to the left and right directions.

[0051] The front and rear adjustment bracket 40 is mounted on the front and rear adjustment assembly 50. One end has a flip-frame connection hole 41 along an axis parallel to the X-direction, through which the pitch adjustment pin 24 passes, connecting to the flip-frame 21 and the night vision device mounting base 11. The front and rear adjustment bracket 40 has a pitch adjustment assembly mounting hole 42 along an axis parallel to the Z-direction, allowing the pitch adjustment knob 31 and transmission screw 32 to be mounted from both sides of the pitch adjustment assembly mounting hole 42, thus mounting the pitch adjustment assembly 30 onto the front and rear adjustment bracket 40. The front and rear adjustment bracket 40 has front and rear adjustment guide holes 43 on both sides in the Y-direction for mounting onto the front and rear adjustment assembly 50. One side wall of the front and rear adjustment guide hole 43 has a snap-fit ​​notch 44 for locking the front and rear adjustment bracket 40 in the Y-direction position.

[0052] The front-to-back adjustment assembly 50 connects the front-to-back adjustment frame 40 and the translation adjustment seat 60, and includes front-to-back adjustment slide rails 51, front-to-back adjustment latches 52, front-to-back adjustment latch return springs 53, front-to-back adjustment latch mounting pins 54, and locking screws 55. Two front-to-back adjustment slide rails 51 are arranged parallel to the Y-direction, and front-to-back adjustment guide holes 43 on both sides of the front-to-back adjustment frame 40 are fitted onto the two front-to-back adjustment slide rails 51. The front-to-back adjustment latches 52 are mounted beside the front-to-back adjustment guide holes 43 with latch notches 44 via the front-to-back adjustment latch mounting pins 54. The front-to-back adjustment latch return springs 53 are compressed and installed between the front-to-back adjustment latches 52 and the front-to-back adjustment frame 40, so that the front-to-back adjustment latches 52 elastically engage with the latch notches 44. A locking screw 55 is installed at the front end of one of the front-to-back adjustment slide rails 51 to lock the front-to-back adjustment frame 40 onto the front-to-back adjustment slide rail 51. Specifically, the front and rear adjustment slide rail 51 is provided with a plurality of slots 511 at intervals, and the front and rear adjustment buckle 52 includes a front and rear adjustment buckle pressing part 521 and a buckle blade 522 provided on both sides of the front and rear adjustment buckle mounting pin 54. The buckle blade 522 can pass through the buckle notch 44 and be inserted into the slot 511 to lock the position of the front and rear adjustment bracket 40 on the front and rear adjustment slide rail 51.

[0053] Please refer to the following: Figure 6 The translation adjustment base 60 includes a slide rail fixing ring 61, a dovetail slide groove 62, and a push rod screw hole 63. The slide rail fixing ring 61 is located on both sides for mounting the front and rear adjustment slide rails 51 respectively. The dovetail slide groove 62 is located on the side facing the helmet mounting base 80 and is opened along the X direction. The dovetail slide groove 62 connects and engages with the translation adjustment assembly 70, allowing it to move relative to the translation adjustment assembly 70 along the X direction (left and right movement). The axis of the push rod screw hole 63 is arranged parallel to the Y direction for mounting the translation adjustment assembly 70.

[0054] The translation adjustment assembly 70 includes a dovetail block 71, a slider 72, a connecting screw 73, a translation adjustment lever 74, a threaded push rod 75, and a lever connecting screw 76. The dovetail block 71 and the dovetail groove 62 slide against each other. The slider 72 has a T-shaped cross-section and is arranged along the Z direction, and is connected to the dovetail block 71 by the connecting screw 73. The translation adjustment lever 74 is connected to one end of the threaded push rod 75 by the lever connecting screw 76. The threaded push rod 75 is installed in the push rod screw hole 63 by threaded engagement. Moving the translation adjustment lever 74 can drive the threaded push rod 75 to move relative to the translation adjustment seat 60 in a direction parallel to the Y direction (back and forth movement) within the push rod screw hole 63. A push rod groove 711 is formed on the dovetail block 71 along the X direction, so that the end of the threaded push rod 75 can be coupled into the push rod groove 711, thereby locking the position of the translation adjustment seat 60 relative to the dovetail block 71.

[0055] The helmet mounting base 80 includes an upper protrusion 81, a lower protrusion 82, a quick-release clip 83, a protrusion return spring 85, and a clip fixing screw 86. The upper protrusion 81 and lower protrusion 82 are respectively located on opposite sides in the Z direction. The upper protrusion 81 is fixed to the helmet mounting base 80, and the lower protrusion 82 is telescopically located on the opposite side of the upper protrusion 81 via the protrusion return spring 85. The quick-release clip 83 is installed via the clip fixing screw 86, and pushing the quick-release clip 83 moves the lower protrusion 82. Specifically, the lower protrusion 82 has a spring positioning notch 821 for the protrusion return spring 85 to abut against. The quick-release clip 83 has a pushing groove 831 for the clip fixing screw 86 to pass through and move relative to it. The lower protruding tongue 82 is provided with a wedge-shaped portion 822 for engaging with the wedge-shaped groove 832 on the quick-release buckle 83, thereby converting the force pushing the quick-release buckle 83 into a force acting on the wedge-shaped portion 822, so that the lower protruding tongue 82 can extend and retract relative to each other.

[0056] The helmet mount 80 has a groove 84 along the Z-direction, allowing the slider 72 to be slidably mounted in the groove 84. This allows the dovetail block 71 to move relative to the slider 72 along the groove 84 in the Z-direction. Conversely, the translation adjustment seat 60, through the engagement of the dovetail groove 62 and the dovetail block 71, can move relative to the dovetail block 71 in the X-direction. The translation adjustment lever 74 and the threaded push rod 75, when pressed from the Y-direction, lock the positions of the translation adjustment seat 60, the dovetail block 71, and the helmet mount 80 in both the X and Z directions, thereby enabling position adjustment in both directions.

[0057] The night vision adapter bracket of this application is used for connecting conventional night vision devices. After installing the night vision device, it allows for conventional structural adjustments, including vertical (Z-axis), horizontal (X-axis), forward / backward (Y-axis), pitch (rotation around an axis parallel to the X-axis), and tilt (switching between drooping and tilted-up states). It adapts to different user face shapes, interpupillary distances, and other adjustment needs. This night vision adapter bracket also enables the connection between the helmet and the night vision device, facilitating quick disassembly.
