Description
Technical field
The present invention relates to night vision goggles technical field, especially a kind of pilot's night vision goggles pin rod formula arming mechanism.
Background technology
Pilot's night vision goggles are arranged on flight crash helmet front portion and are convenient to the direct visualization of pilot, but due to flight crash helmet install night vision goggles additional after the reach of overall centre of gravity place cause pilot's long-time continuous to wear night vision goggles time can produce sense of fatigue.Therefore the mode of being fixedly connected with can not be adopted between pilot's night vision goggles with flight crash helmet; dismountable connected mode should be adopted so that pilot according to circumstances needs to select whether install night vision goggles; when considering aircraft flight, pilot cannot carry out both hands or long-time operation, so should possess the function of singlehanded quick-detachment, installation between night vision goggles mirror body and mounting bracket.Pilot's night vision goggles in use can bear flight overload (being usually not more than 9g) of aircraft, and the bindiny mechanism between pilot's night vision goggles mirror body and mounting bracket should be able to ensure that night vision goggles mirror body does not come off from mounting bracket when 9g transships.
For meeting above-mentioned functions, as shown in Figure 1, be fitted at present not possess between pilot's night vision goggles mirror body of ejecting function aircraft and mounting bracket and generally adopt ball-type elastic solution release mechanism.Utilize the pressure of spring to both sides ball to make ball be stuck in the groove of mounting bracket, make spring provide different elastic force to ensure that night vision goggles mirror body does not come off under 9g overload situations from mounting bracket by the parameter of regulating spring.During the body dismounting of night vision goggles mirror, pilot directly can plug and force ball Compress Spring, just can realize the dismounting of night vision goggles mirror body after ball retraction positioning tube.
The aircraft possessing ejecting function should be noted during equipped pilot's night vision goggles security when launching; flight crash helmet centre of gravity place after equipped night vision goggles is to the front, pilot neck can be caused to sustain damage under the acceleration (>=15g) produced when catapult-launching gear starts.When being separated to ensure to launch with flight crash helmet when therefore visor or should launch startup before launching, night vision goggles do not cause damage to pilot.For realizing this function, (namely start before catapult-launching gear in through canopy ejection mode, utilize ejector seat kinetic energy to wear out hatchcover to aircraft exterior) aircraft on still adopt ball-type elastic solution release mechanism abroad, by adjusting the pressure of parameter change ball to groove of spring, night vision goggles mirror body is not come off when≤9g from mounting bracket, night vision goggles mirror body is separated from mounting bracket when >=15g, ensures that pilot is injury-free.
The ejection mode of aircraft is not all wear lid formula, has considerable aircraft to adopt canopy jettison ejection mode (namely first casting hatchcover aside aircraft, rear startup ejector seat).Because pilot's night vision goggles main components is working of plastics; so pilot's night vision goggles can be damaged under Windblast; likely cause damage to pilot, the pilot's night vision goggles be therefore fitted on canopy jettison ejection mode aircraft need to be separated with flight crash helmet by night vision goggles before lid thrown by aircraft.External this problem that solves adopts two kinds of methods at present: one, manually taken out from mounting bracket by night vision goggles before launching; Two, the priming system between the helmet with mounting bracket is utilized to be separated from flight crash helmet by night vision goggles.
Running time when adopting first kind of way to considerably increase pilot ejection and difficulty, add the risk of ejection escape; When adopting second method, need to ensure that under priming system acceleration (about 30g) effect night vision goggles mirror body can not come off from mounting bracket to avoid secondary separation and cause damage to pilot, this is the elastic force that will increase spring in ball-type elastic solution release mechanism, but elastic force just causes pilot that one hand cannot be used to carry out the fast assembling-disassembling of night vision goggles mirror body after increasing.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of pilot's night vision goggles pin rod formula arming mechanism, ensure that pilot's night vision goggles bear large overloading acceleration (>=40g) Shi Jingti and do not come off from mounting bracket, pilot singlehanded can realize the installation and removal between mirror body and mounting bracket simultaneously.
In order to solve the problems of the technologies described above, the present invention includes mounting bracket body and night vision goggles body, the link sidewall of described night vision goggles body is provided with the first pilot hole be located along the same line and the second pilot hole, described mounting bracket body is provided with the groove corresponding with the first pilot hole and the second pilot hole, the first place kick is provided with in described first pilot hole, the second place kick is provided with in described second pilot hole, the part sphere of described first place kick and the second place kick is positioned at groove, the backstay running through the first place kick and the second place kick is also provided with in described night vision goggles body link, described backstay and clearance fit between the first place kick and the second place kick, described backstay is also fixedly installed the limited block being positioned at the first pilot hole, between described limited block and the first place kick, and second bottom pilot hole and be provided with spring between the second place kick, described mounting bracket body is also provided with the through hole and spacing hole that are located along the same line with backstay, push rod is provided with in through hole, described push rod one end is positioned at mounting bracket body exterior, described rod diameter is less than backstay diameter, and coordinate with via clearance, described push rod is also provided with the first draw-in groove and the second draw-in groove, jump ring is provided with between described push rod and mounting bracket body.
When night vision goggles are installed, push push rod, described backstay enters spacing hole on mounting bracket body through place kick, realizes being rigidly connected, therefore, it is possible to night vision goggles body does not come off from mounting bracket body when ensureing large overloading acceleration (>=40g) of night vision goggles body and mounting bracket body.During dismounting night vision goggles, extract push rod, described backstay is positioned at night vision goggles body completely under the Hui Li of spring and the effect of limited block, at this moment be only connected with the second place kick by the first place kick between night vision goggles body and mounting bracket body, rely on one hand to be just easy to night vision goggles to be separated with mounting bracket.
