The fixing bracket 300 is also provided with a power switch 600 electrically connected to the battery pack 200. The fixing bracket 300 is connected with a head-mounted bracket of a human head. A head-mounted bracket connecting piece 700 is arranged above the fixed bracket 300, and a height increasing block 800 is arranged between the fixed bracket 300 and the head-mounted bracket connecting piece 700.

The rotary damping mechanism 400 includes a rotary damper 410, one end of the rotary damper 410 is connected to the fixed bracket 300, the other end is connected to the sliding block 420, the sliding mechanism 500 includes a first sliding table 510 and an adjusting screw 520, as shown in fig. 5, a first sliding groove 530 is arranged above the first sliding table 510, the first sliding groove 530 is slidably connected to the sliding block 420, and a screw hole 540 which is in threaded connection with the adjusting screw 520 is arranged on one side of the first sliding groove 530 on the first sliding table 510. The adjusting screw 520 is rotated clockwise or counterclockwise, the observation mirror 100 is driven by the first sliding table 510 to slide left and right in the transverse direction by the sliding fit of the first sliding groove 530 and the sliding block 420, and the transverse adjustment of the eye distance of the observation mirror 100 is realized.

In addition, on the basis that the observation mirror 100 can perform the eye distance lateral adjustment, the observation mirror 100 can perform the upward and downward rotation adjustment, and the wider eye distance adjustment can be provided. When the observation mirror 100 is rotationally adjusted upward and downward, the radian can reach 85.5 degrees at most, and a single-side or double-side overturning state is realized by simultaneously or independently rotating the observation mirrors 100 on two sides, as shown in fig. 10 and 11. When the device is placed on top of a helmet by a helmet mount, the large arc of rotational adjustment allows the sight glass 100 to be closer to the helmet, allowing the weight of the night vision device to be more evenly distributed across the helmet, further reducing weight perception when worn.

As shown in fig. 6, a second sliding chute 550 is arranged at the bottom of the first sliding table 510, a first locking device 560 is arranged on the first sliding table 510, as shown in fig. 7, the first locking device 560 includes a locking switch 561 slidably connected above the first sliding table 510 and a locking pin 562 fixedly connected below the locking switch 561, the locking pin 562 extends from a movable groove on the first sliding table 510 into the second sliding chute 550, a sliding seat 110 slidably connected with the second sliding chute 550 is arranged on the observation mirror 100, a pin hole 120 capable of being matched with the locking pin 562 is arranged on the sliding seat 110, when the observation mirror 100 is installed, the locking switch 561 and the locking pin 562 are pulled out, the sliding seat 110 is slidably inserted into the second sliding chute 550, when the observation mirror 100 is installed, the locking switch 561 and the locking pin 562 are pushed in, and the locking pin 562 and the pin hole 120 form a limit connection to lock the observation mirror 100. When the observation mirror 100 needs to be detached, the locking switch 561 and the locking pin 562 can be pulled out again, the limit of the locking pin 562 to the pin hole 120 is lost, and the observation mirror 100 and the sliding seat 110 can be pulled out from the second sliding groove 550, so that the observation mirror 100 can be detached. The bottom of the first sliding table 510 is also provided with a lightening groove 590.

A first conductive contact row 250 electrically connected with the battery assembly 200 is disposed below the fixing bracket 300, a second conductive contact row 430 is disposed below the slider 420, the first conductive contact row 250 and the second conductive contact row 430 both include a plurality of conductive tin bars 251 disposed in parallel, as shown in fig. 9, the first conductive contact row 250 and the second conductive contact row 430 are driven by the rotation of the rotary damping mechanism 400 to form a separation or contact electrical connection, a contact mounting groove 130 is disposed on the sliding base 110, a pogo pin contact 140 is disposed in the contact mounting groove 130, as shown in fig. 8, a slot 570 is correspondingly disposed on the first sliding table 510, a contact quick mounting 580 guide groove is disposed at a side of the first sliding table 510, one end of the pogo pin contact 140 is electrically connected with the observation mirror 100, and the other end of the pogo pin contact 140 extends out of the slot 570 to be connected to the second conductive contact row 430.

When the rotary damping mechanism 400 does not rotate, the first conductive contact bank 250 is in contact electrical connection with the second conductive contact bank 430, the pogo pin contact 140 of the observation mirror 100 is connected with a power supply, the observation mirror 100 is powered on, when the rotary damping mechanism 400 on one side or two sides rotates to enable the first conductive contact bank 250 to be in contact electrical separation with the second conductive contact bank 430, the pogo pin contact 140 of the observation mirror 100 on the side is disconnected with the power supply, the observation mirror 100 is powered off and automatically powered off, a single-side or double-side independent switching function (a master power switch 600 is in an on state) is realized, the power supply of a night vision device is not required to be manually turned off, and the low-light-level image intensifier tube is automatically.

The traditional direct power supply connection between the left and right transverse eye distance adjustment and the observation mirror 100 is realized through wires inside the bracket, and the long-time use of the transverse eye distance adjustment can cause the internal wires to be frequently pulled, so that the wires are aged too fast, and the structure of the type needs to ensure that the inside of the bracket is in a hollow state, so that the shock resistance of the bracket is reduced greatly; and this embodiment adopts spring pin contact 140 and electrically conducts the bank of contacts and connects the power supply, has avoided walking the line in the support, has saved inside electric wire to can become solid construction with the support is inside, strengthened the intensity of support promptly, avoided the electric wire ageing that leads to again many times horizontal eye distance adjustment.
