Description
Technical field
The utility model relates to a kind of preventing atomization night vision vehicle-mounted cameras, belong to camera technical field.
Background technique
With advances in technology and develop, and economic fast development, automobile has been increasingly becoming the weight in people's life
The vehicles are wanted, corresponding vehicle-mounted camera also becomes the necessary equipment that car owners install, and vehicle-mounted camera can be traffic
The analysis of accident determines to provide reliable voucher, facilitates driver and passenger to check interior situation, look into for passenger inside the vehicle's dispute, lost article
Look for, antikijacking burglar the problems such as generation provide processing foundation, the monitoring of compartment internal and external environment is provided, provides safety for vehicle driving
It ensures.Infrared night vision vehicle-mounted camera in the prior art, using the infrared illumination lamp of itself as light source, low speed is taken the photograph
As head captures infrared imaging, to obtain the ambient image at night, the function of night vision is realized；But in microthermal climate, outside
Shell temperature is low, and air themperature is high in shell, and liquefaction forms water droplet in housing skin after contacting shell, influences near camera acquisition
Image information；So need it is a kind of can be in the preventing atomization vehicle-mounted camera that low temperature night uses.
Utility model content
The purpose of this utility model is to provide a kind of preventing atomization night vision vehicle-mounted cameras, the specific scheme is that
A kind of preventing atomization night vision vehicle-mounted camera, including shell and camera body, camera body are arranged inside the shell
Portion, the front end of the shell are equipped with opening, the front end direction opening of camera body；The opening of the shell is equipped with transparent
Protecting cover, protecting cover include preceding cover and rear cover body, and the opening of shell is equipped with tubaeform expansion segment in front of preceding cover,
The junction of preceding cover and shell is equipped with preceding ventilation hole, is installed with spacing between the rear cover body and preceding cover, in rear cover body
Portion is equipped with transition air holes；Ventilating duct is installed between the shell and camera body, the rear portion of shell is equipped with back vents, and
Exhaust fan is equipped at back vents；The back vents and transition air holes are penetrated through by ventilating duct, transition air holes and preceding ventilation hole
It is penetrated through by the gap of rear cover body and preceding cover.
Further, the shell is cylindrical body, and the inner sidewall of shell is equipped with multiple spaced support plates, support plate
Length direction and cylinder it is axial consistent, the gap between support plate is ventilating duct；Support plate is connect with camera body.
Further, the preceding ventilation hole is equipped with the retaining ring of protrusion, and retaining ring front end is equipped with Air Filter.
Further, the camera body is located at the transition air holes of rear cover body.
The beneficial point of the utility model is: in the present solution, inside the housing by camera body setting, before shell passes through
Ventilation hole, back vents realize ventilation, carry out demisting to cover surface using ventilation, the shooting effect of camera can be kept clear
It is clear.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram of preceding ventilation hole in the utility model；
Fig. 3 is the Section A-A schematic diagram in Fig. 1.
Specific embodiment
A kind of preventing atomization night vision vehicle-mounted camera as shown in Figs. 1-3, including shell 1 and camera body 2, in order to meet
Night vision function, camera body are additionally provided with LED and infrared illumination lamp except pick-up lens is provided with, and the setting of camera body 2 exists
Inside shell 1, shell plays a protective role to camera body, and camera body is prevented to be scratched or impact failure.Shell
Front end is equipped with opening, the front end direction opening of camera body；The opening of shell is equipped with transparent protecting cover.
Since traditional shell is using closed, there are the temperature difference, the translucent cover inner side and outer side of shell is equal
It is possible that hazing, need to wipe in time, wiping processing can not be carried out when hazing on the inside of translucent cover.The protecting cover packet of this programme
Cover 3 and rear cover body 4 before including, the opening of shell 1 are equipped with tubaeform expansion segment 5 in front of preceding cover, preceding cover and shell
Junction is equipped with preceding ventilation hole 6, and spacing is installed between rear cover body and preceding cover, and the middle part of rear cover body is equipped with transition air holes 7；Outside
Ventilating duct 8 is installed between shell and camera body, the rear portion of shell is equipped with back vents 9, and air draft is equipped at back vents 9
Fan 10；Back vents and transition air holes are penetrated through by ventilating duct, and transition air holes and preceding ventilation hole pass through rear cover body and preceding cover
Gap perforation.After exhaust fan starting, formed along preceding ventilation hole, the gap of rear cover body and preceding cover, transition air holes, ventilation
The air-flow that road, back vents flow can carry out demisting to cover surface, prevent from being atomized, to keep camera shooting clear
Degree.
It is designed as a kind of specific structure, in the present embodiment, shell 1 is cylindrical body, and the inner sidewall of shell is equipped with multiple
Spaced support plate 11, the length direction of support plate and the axial direction of cylinder are consistent, and the gap between support plate is ventilating duct
8；Support plate 11 is connect with camera body 2.Support plate plays the supporting role to camera body, is formed simultaneously ventilating duct.
The rubber slab with damping effect can be used in support plate, plays better protective effect to camera body, prevents it from being rushed
It hits.
As an improvement structure, the present embodiment preceding ventilation hole be equipped with protrusion retaining ring 12, retaining ring cover facing forward
Outside protrusion, retaining ring front end are equipped with Air Filter 13.When the structure can prevent front shroud body surface face from having ponding, ponding is along preceding ventilation hole
Enclosure interior is flowed into, the purpose that Air Filter is arranged is to prevent dust from entering enclosure interior.
Alternatively improved design, camera body are located at the transition air holes of rear cover body.Air-flow is along mistake in this way
Cross air holes flow into when, can the camera lens part to camera body also function to demisting effect.
