Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with execution mode.
The design of the utility model most critical is: the utility model arranges fan component and heating component in the enclosure interior of picture pick-up device, can remove the fog inside cover glass, plays preferably IMAQ effect.
Refer to Fig. 1 to Fig. 4, the demist assembly of cover glass in a kind of picture pick-up device, comprise by fore shell 3, the closure casing that body 1 and back cover 35 surround, photographing module 4 is provided with in housing, described fore shell 3 offers opening, described opening is fixed with cover glass 34, demist assembly is provided with in described housing, described demist assembly comprises fan component 2, heating component 5 and controller, described fan component 2 is fixed on inside body 1, described heating component 5 comprises warm and humid transducer 31, heater pressing plate 32 and heater 33, described warm and humid transducer 31 is fixed on heater pressing plate 32, heater 33 presses on cover glass 34 by described heater pressing plate 32, described controller is electrically connected with fan component 2 and heating component 5 respectively.
From foregoing description, the beneficial effects of the utility model are: the utility model arranges fan component and heating component in the enclosure interior of picture pick-up device, during fan component energising, drive the air circulation of enclosure interior, reduce endosome interior humidity difference and temperature difference, the fog inside cover glass can be removed, and heating component can heat cover glass, to reduce the temperature difference of enclosure interior temperature and external environment condition, can improve except fog effect further, to sum up, the demist of this device is effective, is convenient to the IMAQ of picture pick-up device.
Consult Fig. 2, further, described fan component 2 comprises air blast 21 and mounting bracket 22, and described mounting bracket 22 is fixed on case inside wall, and described air blast 21 is fixed on mounting bracket 22.
Further, also comprise screw, described mounting bracket 22 is provided with the projection 23 of band screw, correspondingly on described air blast 21 is provided with through hole 24, and screw is bolted on projection 23 through after through hole 24.The structure that screw is fixed is more stable, the mode of clamping can certainly be used to fix, as through hole and projection directly coordinate fixing structure.
Further, described heater pressing plate 32 is provided with reference column 36, correspondingly on described warm and humid transducer 31 is provided with location hole 37.Above-mentioned location hole 37 can be directly fixed on reference column 36, and the structure certainly selecting other fixed structure that warm and humid transducer and heater pressing plate are fixed also is feasible program.
Further, described cover glass 34 is bonded and fixed on fore shell 3.Bonded structure is most preferred scheme, certainly can also arrange space structure or other structures of a clamping cover glass at fore shell 3.
In concrete application, this device can according to the change of humiture in housing by the open and close of specific program auto controlled heater and air blast to reach the formation preventing fog.When humidity is lower than a certain set point, if ambient temperature is lower than a certain set point, a heater, controls glass internal-external temperature difference to prevent the formation of fog, if temperature is higher than a certain set point, heater cuts out; When humidity is higher than a certain set point, heater and air blast are opened simultaneously, control the humidity of glass inner side to prevent the formation of fog, after running the time of a certain setting, continue to detect humiture change.Realize thus in the process of ambient temperature and humidity change, fog can not be formed all the time, and this control procedure both ensure that the life-span of air blast, thus increases the reliability of demist scheme, also by the switch of warm and humid transducer and procedure auto-control demist module, thus the intelligent of demist scheme is increased.
In sum, in the picture pick-up device that the utility model provides, the demist assembly of cover glass arranges fan component and heating component in the enclosure interior of picture pick-up device, during fan component energising, air blast rotates the air circulation driving enclosure interior, reduce endosome interior humidity difference and temperature difference, the fog inside cover glass can be removed, and during heating component energising, can heat cover glass, to reduce the temperature difference of enclosure interior temperature and external environment condition, can improve except fog effect further, to sum up, the demist of this device is effective, be convenient to the IMAQ of picture pick-up device, in addition, the fixed structure of air blast and mounting bracket in this device, and the fixed structure of warm and humid transducer and heater pressing plate is firm, the shock resistance of whole equipment is better.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
