According to the helmet night-vision device, under the low illumination environment, the helmet night-vision device is capable of really reflecting actual situations of on-site pictures by utilizing near-infrared auxiliary illumination.
Description
Technical field
The utility model relates to a kind of helmet night vision device.
Background technology
Society enters the information age, and along with the development of technology, military affairs also start innovation.Low-light Level Night Vision Technology and infrared thermal imaging technique gradually at home the military grow up, its application is subject to attracting attention of more and more people, but in some specific occasions, for example: when engineer carries out field maintenance night, use infrared thermal imaging equipment, can not distinguish well each parts situation of machine, and expensive; And low-light equipment can reflect actual conditions preferably, but a chance high light is easy to burn out, and low-light equipment price is also higher.
Summary of the invention
For this reason, the purpose of this utility model is to provide a kind of helmet night observation device, low, according in environment, utilizes near infrared floor light, can reflect really live view actual conditions.
The technical solution adopted in the utility model is:
A kind of helmet night vision device, comprise the helmet, be arranged on the fixed support of helmet front side, and be arranged on the optical module on fixed support, described optical module comprises infrared imaging assembly and near infrared lighting module, and the display module eyepiece that output is connected with display module that mates this infrared imaging assembly.
From said structure, can find out, according to the utility model, utilize near infrared lighting module to throw light on, naked eyes are invisible, by infrared imaging assembly, carry out imaging, carry out the real-time monitored of video image by eyepiece, disguised more intense.The infrared imaging camera lens that matches is not easy to be burnt out by high light, and equipment cost is relatively also low.
Above-mentioned helmet night vision device, adapts to the power module device of described optical module at the rear side of the described helmet.
Above-mentioned helmet night vision device, described power module is the lithium battery module with charging circuit.
Above-mentioned helmet night vision device, described near infrared lighting module is that output wavelength is the near infrared lighting module of 940nm.
Above-mentioned helmet night vision device, described fixed support is included in the track that arranges on helmet surface fore-and-aft direction, is disposed at the snap close on track and is connected in the seat on snap close, wherein said seat is connected on described snap close by the rotating shaft of level, and described rotating shaft is furnished with latch mechanism.

In figure: 1, lighting module, 2, infrared imaging assembly, 3, display module, 4, power module, 5, eyepiece, 6, fixed support, 7, the helmet.
Embodiment
With reference to the theory diagram of helmet night vision device shown in explanation accompanying drawing 1, it has five essential parts, is respectively power module and lighting module, image-forming assembly, the display module that has power module driving, and is docked at the eyepiece on display module the corresponding interface.Under the lower condition of environment irradiance, by lighting module, provide floor light, outside scenery is by after image-forming assembly, and output packet, containing the analog video signal of target information, is carried out picture disply at display module, with eyepiece, observes.
Fig. 2 a, Fig. 2 b have provided a kind of physical construction schematic diagram of helmet night vision device, comprise lighting module 1, infrared imaging assembly 2, display module 3, power module 4, eyepiece 5, fixed support 6 and the helmet 7.
Correlated characteristic content once is first described here, is mainly the part of floor light, and namely lighting module 1, obviously should in exit direction, mate with infrared imaging assembly, and this those skilled in the art should be had clearly and be understood.Be different from visible ray and common infrared equipment, adopt the lighting module 1 of near-infrared band, human eye is invisible, and the impact that in addition corresponding infrared imaging assembly 2 is subject under high light condition is relatively also smaller.
Near infrared (near infrared), wavelength is at the electromagnetic wave of 780～3 000nm scopes.
Near infrared region is the non-visible light region that people find the earliest.But a little less than frequency multiplication and sum of fundamental frequencies absorption signal due to material Gai Pu district, bands of a spectrum are overlapping, resolve complexity, limited by technical merit at that time, near infrared spectrum " has been sunk into sleep " nearly a century and a half.Near infrared spectrum belongs to frequency multiplication and the dominant frequency absorption spectrum of molecular vibration spectrum, is mainly that anharmonicity due to molecular vibration produces while making molecular vibration from ground state to high level transition, has stronger penetration capacity.
Conventional near infrared illumination semiconductor laser wavelength mainly contains 808nm, 880nm, 915nm etc., at running hours, all has the red phenomenon of exposing to the sun.Select the near infrared ray of the longer near-infrared band of wavelength, can effectively eliminate red exposing to the sun.
Therefore, preferably, described lighting module 1 is near-infrared LED light source, and wavelength is 940nm, and human eye is invisible, good concealment; The longer near infrared ray of wavelength is followed following rule, and wavelength is longer, and the responsiveness of low-light charge coupled device ccd is just lower, thereby detection range is relatively short.Because this case is mainly used in the use of combat maintenance, do not need long detection range, thereby effectively balance above-mentioned defect.Therefore, adopt the near infrared ray lighting module that wavelength is 940nm to there is good adaptability.
Power module 4 is rechargeable lithium battary, powers to each sub-module, guarantees lighting module 1, infrared imaging assembly 2 and the normal steady operation of display module 3.
Helmet night vision device is fixed on the helmet 7 front ends by fixed support 6, and power module 4 is fixed on the helmet 7 rear ends, for the balance helmet 7 front end weight.Fixed support 6 used is a kind of adjustable jack post, in use can pass through the front and back position of guide rail front and back adjusting helmet night vision device, and then regulates eyepiece to the distance of human eye, convenient observation.
After helmet night vision device uses, after being adjusted to foremost by guide rail, rotary fixed bracket 6, can rotate to the helmet night vision device helmet 7 tops, by the auto-lock function of fixed support 6, helmet night vision device is locked, and the equipment that prevents overturns under the effect from gravity.Fig. 3 a, Fig. 3 b, Fig. 3 c are the adjusting schematic diagram of helmet night vision device, and Fig. 3 a is for regulating initial position, and Fig. 3 b is a certain position in adjustment process, and Fig. 3 c is position after rotary self-locking.
From said structure, can find out, (1) helmet night vision device is fixedly mounted on the helmet, small volume and less weight, and convenient and practical, cost is low.(2) by eyepiece, can carry out the real-time monitored of video image, disguised strong.
