Description

Technical Field

[0001] The present invention relates to the technical field of night vision goggle side-turning brackets, and specifically to a multifunctional night vision goggle side-turning bracket. Background Art

[0002] In current night vision devices, night vision goggles are very important tools and are widely used in military, security, hunting and other fields. The designs of traditional night vision goggles are usually relatively single in terms of structure and function. There is still room for optimization, especially in terms of portability, ease of use, battery life and wearing stability.

[0003] Most of the existing night vision goggle brackets adopt fixed designs and lack convenient storage. In addition, when traditional night vision goggles are stored, they are directly turned over the head, which results in an unstable center of gravity and is likely to cause discomfort when worn. In addition, the power management of traditional night vision goggles usually relies on gravity switches or conventional switches to control power on and off. When not in use, if the switch is forgotten to be turned off, the night vision goggles will always be in the working state, resulting in waste of power, affecting the battery life of the device, and in some usage scenarios, the operation is still not fast or flexible enough.

[0004] At the same time, the existing night vision goggle brackets are relatively single in terms of adjustment and usage methods and cannot be quickly switched between binocular and monocular modes conveniently, which affects the adaptability of night vision goggles in different observation scenarios. Summary of the Invention

[0005] Aiming at the above deficiencies in the prior art, the purpose of the present invention is to provide a night vision goggle side-turning bracket that is convenient for storage, has strong wearing stability, is convenient for free switching between single-eye and binocular use, and has high operability.

[0006] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a multifunctional rollover bracket for night vision goggles, including a bracket upper shell, a bracket lower shell, a swing arm, and a distance adjustment component. A triangular fixture is fixedly connected to the middle part of the upper end of the bracket upper shell, and the triangular fixture is used to achieve relative connection with the mounting bracket. The mounting bracket is fixedly installed on the helmet, so as to facilitate users to wear and use it. The lower end of the bracket upper shell is connected to the bracket lower shell, and the rear end of the bracket upper shell is fixedly installed with a fixing plate by bolts. Flip grooves are respectively arranged between the two ends of the fixing plate and the bracket upper shell. The flip groove provides an installation space for the rotation of the swing arm, and a long screw After passing through the fixing plate, it is threadedly connected to one side of the inner wall of the flip groove. A rotating shaft hole passes through one end of the swing arm. The swing arm is rotatably connected to the long screw in the flip groove through the rotating shaft hole. That is to say, the two groups of swing arms are rotatably connected to the flip grooves on both sides of the upper shell of the bracket. By flipping the swing arm upward, the storage or carrying of the device can be convenient. The two ends of the upper shell of the bracket are respectively connected with a flip switch, and the flip switch is used to control the rotation of the swing arm. The flip switch corresponds to a positioning piece at one end of the swing arm, and the positioning piece is used to relatively fix the swing arm that flips upward. An adjusting groove is provided at the upper end of the swing arm. A slot cover is fixedly connected to the notch by bolts, and a distance adjustment component is connected in the adjustment slot, and the distance adjustment component is used to adjust the position of the main tube on the swing arm, so that the night vision device can adapt to the position of the user's eyes. The distance adjustment component is connected to a connecting seat, and the connecting seat is slidably connected to the lower end of the swing arm. The connecting seat is fixedly connected to the main tube by bolts, and the main tube is a mounting shell of the night vision device. A limit strip is fixedly connected in the flipping slot, and one end of the swing arm is set as a semicircular arc surface, and a slot edge is set on one side of the semicircular arc surface, and the slot edge conflicts with the limit strip, and the slot edge and the limit strip limit the swing arm to flip downward, and the slot edge is A magnet is embedded and connected on the swing arm on the side, a PCB board is installed in the upper shell of the bracket, and magnetic switches are respectively arranged on the edges of the two sides of the PCB board. The magnet is magnetically connected to the magnetic switch through magnetic flux lines. When in use, the night vision device can be conveniently turned on or off by changing the position of the magnet and the magnetic switch. That is, when in use, after the swing arm is flipped upward, the magnet and the magnetic switch are staggered, so that the magnetic switch cannot sense the magnetic flux lines, thereby turning off the work of the night vision device. After the swing arm is flipped downward and unfolded, the distance between the magnet and the magnetic switch is shortened. When the magnetic switch senses the magnetic flux lines again, the working state of the night vision device is automatically turned on.

[0007] In the present invention, the side turning operation of the night vision device can be achieved by the flipping of the swing arm. During specific use, the swing arm can complete a side turning rotation of 96° upward. After the swing arm completes the flipping operation upward, the relative fixation of the swing arm can be achieved through the positioning member, that is, the swing arm is relatively fixed to the upper shell of the bracket. At this time, the swing arm cannot rotate on the upper shell of the bracket, thus facilitating the storage operation of the device. When it is necessary to flip the swing arm downward back to the starting position, it is necessary to press the side turning switch. By pressing the side turning switch, the fixed state of the positioning member on the swing arm is released, so that the swing arm can be flipped downward.

[0008] In the above technical solution, a mounting seat is fixedly connected to the middle of the upper end of the upper shell of the bracket. An installation groove is opened in the middle of the upper end of the mounting seat. An installation block is fitted and connected in the installation groove. The installation block is fixedly connected to the lower end of the triangular fixture. The triangular fixture is used to achieve the relative connection with the installation bracket. The installation bracket is fixedly installed on the helmet. An installation hole penetrates through the triangular fixture and the installation block. After the bolt passes through the installation hole, it is threadedly connected to the bottom of the installation groove to achieve the fixed connection between the upper shell of the bracket and the triangular fixture. Limiting grooves are respectively opened on the triangular fixture on both sides of the installation block. A limiting block is opened on the mounting seat on one side of the installation groove. The limiting block is inserted and connected in the limiting groove to position the installation position of the triangular fixture. In this embodiment, the upper shell of the bracket is the basic structure of the side turning bracket, which is used to achieve the installation connection of the lower shell of the bracket and the swing arm.

[0016] Advantages of the present invention:

[0017] 1. Convenient storage function: The present invention adopts a two-sided side-turning design, which can significantly reduce the overall volume of the night vision device. When not in use, the bracket and the night vision device can be quickly folded and stored, which is convenient for storage and carrying. In addition, this design is also beneficial to product packaging and transportation, reducing space occupation.

[0018] 2. Intelligent shutdown function: By replacing the traditional gravity switch with a magnetic induction switch, the night vision device can be automatically turned off after side-turning. This not only realizes a faster and more flexible shutdown operation, but also can save battery power and extend the service life of the device.

[0019] 3. Disperse the weight and improve the wearing stability: When traditional night vision devices are stored, they usually turn the device over to the top of the head, which results in an unstable center of gravity and causes discomfort when worn. However, through the flip design of the swing arms on both sides, the present invention can effectively disperse the weight, improve the stability during wearing, and enhance the user comfort.

[0020] 4. Binocular to monocular function: The side flip design of the bracket not only facilitates storage and saves space, but also enables the function of switching from binocular night vision to monocular night vision. Users can choose to flip the left or right swing arm according to their needs to switch to the monocular night vision mode, which helps for close-range observation and adapts to different usage scenarios, especially in cases where a fine observation of the environment is required.

[0021] 5. Improve the operation convenience: The design of the knob switch enables users to conveniently switch the working state of the night vision device, enhancing the flexibility and convenience of device use. In addition, the design of the detent ball in the flip slot and the detent groove ensures the smoothness and stability of the swing arm rotation process, avoiding damage caused by too fast rotation speed of the swing arm.

[0022] 6. Modular design: Each component of the bracket, such as the swing arm, distance adjustment component, mounting block, etc., adopts a modular design, which is convenient for disassembly, installation and maintenance, and improves the maintainability and service life of the device.

[0040] Please refer to Figures 7-9, in the above technical solution, the rollover switch 104 includes a push button 600, a second snap ring 601, a first spring 602, and a push rod 603. Adjustment holes 604 are respectively opened at both ends of the upper bracket shell 1. The push button 600 is slidably connected in the adjustment hole 604. One end of the push button 600 is fixedly connected to the push rod 603. The end of the push rod 603 passes through the adjustment hole 604 and touches the positioning member 105. A first spring 602 is sleeved on the push rod 603. One end of the first spring 602 abuts against the inner wall of the adjustment hole 604, and the other end of the first spring 602 abuts against the push button 600. A second snap ring 601 is connected to the outer end orifice of the adjustment hole 604. One end of the push button 600 passes through the adjustment hole 604 through the second snap ring 601; the positioning member 105 includes a positioning pin 700, a second spring 701, and an internal hexagonal threaded block 702. A first side position hole 703 penetrates through the swing arm 3 on one side of the rotating shaft hole 103. The positioning pin 700 is slidably connected in the first side position hole 703. One end of the positioning pin 700 passes through the first side position hole 703 and is inserted and connected to one end of the adjustment hole 604. A second spring 701 is sleeved in the first side position hole 703. One end of the second spring 701 abuts against the positioning pin 700. The other end of the first side position hole 703 is threadedly connected with an internal hexagonal threaded block 702. The other end of the second spring 701 abuts against the internal hexagonal threaded block 702. After the swing arm 3 is turned up by 96° angle, one end of the positioning pin 700 slides to the adjustment hole 604 inside the flipping groove 102, and under the elastic force of the second spring 701, the end of the positioning pin 700 is directly inserted into the adjustment hole 604. At this time, due to the obstruction of the positioning pin 700, the swing arm 3 is relatively fixed in the flipping groove 102. But when the swing arm 3 needs to be turned down to the original position, press the push button 600. The push button 600 pushes the push rod 603 to push out the positioning pin 700 inserted into the inner side of the adjustment hole 604, so that the swing arm 3 returns to the free rotation state; a second side position hole 800 is opened on the swing arm 3 on the other side of the rotating shaft hole 103. A collision pin bead 801 is fixedly connected to the orifice of the second side position hole 800. A plurality of bead grooves 802 are opened on the inner wall of the flipping groove 102 on the opposite side of the collision pin bead 801. One end of the collision pin bead 801 is fitted with the bead groove 802. During the downward flipping process of the swing arm 3, the fitting of the collision pin bead 801 and the bead groove 802 plays a role in positioning and braking, avoiding damage caused by the too fast rotation speed of the swing arm 3.

[0041] The beneficial effects of the present invention are as follows:

[0042] In the present invention, the multifunctional side-turning bracket of the night vision device can reduce the structural volume of the device through the side-turning of the two side arms 3, thereby facilitating the storage and carrying of the device, and also being beneficial to the packaging and transportation of the device. In addition, a magnet 112 is provided at one end of the side arm 3 of the device, and the magnet 112 is arranged opposite to the magnetic induction switch 113 in the turning slot 102, so that the night vision device on one side of the side arm 3 can automatically turn off after being turned upwards, thereby saving the power of the rechargeable battery 306 and improving the endurance of the device. In addition, when the device is stored, the side arms 3 and the night vision devices located on both sides of the upper shell 1 of the bracket turn to both sides respectively, thereby dispersing the overall weight of the device and improving the stability after being worn by the user. Finally, during use, the side arm 3 on one side of the upper shell 1 of the bracket (the side arm 3 on the left or right side of the upper shell 1 of the bracket) can be turned over, so as to change from binocular night vision use to monocular night vision use, which is beneficial for the user to observe the nearby environment and also take into account the observation situation of the night vision device in the distance.
