Embodiment
In order that those skilled in the art more fully understand the present invention program, below in conjunction with the embodiment of the present invention
Accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only this
Invention part of the embodiment, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art exist
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
The camera that the present embodiment provides keeps away water installations, can be arranged in outdoor monitoring system, excludes rainwater to shooting
The influence of head IMAQ quality, including camera, source of the gas and airway tube, the arrival end of the airway tube connect with the source of the gas
Connect, for the gas with certain pressure that source of the gas provides to be blowed to the camera lens surface of camera by the port of export of airway tube,
The port of export of the airway tube is not located in the image acquisition region of camera.
The principle of the present embodiment is as shown in figure 1, i.e. use can provide the source of the gas of certain pressure gas, such as in the market independence
The EAP Electronic Air Pump of sale, or the air pump carried on automobile, stopped for example, some automobiles are gas, so itself has air pump system,
A source of the gas as gas can be separated, is blown by using the gas of certain pressure on the camera lens surface of camera, can be with handle
The rainwater on camera lens surface is blown away, so that the image of camera collection is not influenceed by rainwater substantially.
It should be noted that certain pressure gas can be blowed to camera lens by the port of export of airway tube except camera lens to be aligned
Surface, it is also noted that the port of export can not be located in the image acquisition region of camera, to have from camera with a certain distance from, in order to avoid
The IMAQ quality of image camera, at the same export from camera have with a certain distance from also can guarantee that the gas of certain pressure can
Rainwater is blowed into opposite side from the side of camera lens, makes Rain-removing more thorough.
In the present embodiment, the pressure limiting valve of air pump can also according to the water size on camera lens surface, be adjusted to adjust gas
Pressure, as long as can ensure camera collection picture quality.
In another embodiment, this camera can be kept away water installations and be applied on automobile, specifically can be used for automobile
Reverse image camera or rearview camera.As shown in Fig. 2 the device includes camera 1, electric air pump (does not show on figure
Go out), airway tube 3 and connector 5, the port of export of the camera 1 and airway tube 3 is connected to one knot by connector 5
Structure.
Specifically, the connector 5 is provided with the first cavity for accommodating camera 1, and the camera 1 is empty through described first
Chamber, the first cavity is exposed on the surface of camera lens 2 of camera 1, to realize the IMAQ to road conditions.
Further, the connector 5 is additionally provided with the second cavity for accommodating airway tube 3 and connected with second cavity
Air outlet 4, the airway tube 3 passes through second cavity, and the port of export of the airway tube 3 connects with the air outlet 4, institute
The air-out direction for stating air outlet 4 is directed at the surface of the camera lens 2, and air outlet 4 can not be located at the image acquisition areas of camera 1
In domain, it is therefore desirable to which air outlet 4 has certain distance to camera lens surface.
In order that airflow direction is more concentrated, gas pressure is bigger, and removal rainwater effect is more preferable, can be by the air outlet 4
Flat pattern is shaped to, can specifically be set away from the distance to camera lens surface according to air outlet as the length of air outlet
Fixed, generally, air all can be fan-shaped after an aperture sprays, due to needing to avoid air outlet interference figure picture, air outlet with
Camera lens surface has a certain distance, and the sector that this distance allows for air-out can be with close to camera lens surface and air-out area
Progressively become big, as long as therefore air outlet length can guarantee that and can cover whole camera lens surfaces when gas reaches camera lens surface,
Thoroughly to remove rainwater above.
In one embodiment, when the camera passes through the first cavity, be able to will be imaged by way of glue sticking
Head is fixed in the first cavity；Or also fastening screw can be set on the first cavity wall, the camera of the first cavity will be stretched into
Clamp, as long as camera can be fixed in the first cavity, camera is formed a fixed connection with connector, it is specific solid
Determine mode the present embodiment do not do it is unlimited.
In another embodiment, the air outlet 4 can be the hard tube structure of flat pattern, and airway tube can pass through
Tracheae adapter and air outlet are attached, or, one end of the second cavity can be arranged to the air-out with connector one
Mouthfuls 4, when airway tube from the other end penetrates the second cavity and during with the second cavity fixed seal connection, the gas with certain pressure
Can be to be blown out by the port of export of airway tube by the second cavity from air outlet 4, so as to simplify the structure of the present apparatus.
When camera as described above is kept away into water installations be applied in vehicle, camera and air outlet can be integrated in
Structure together is arranged on the position of vehicle camera, meanwhile, the arrival end of airway tube can connect independent EAP Electronic Air Pump, example
The CJP95-C12A2 models of Xiamen Conjoin Electroncis Technology Co., Ltd., the 5.0L/min of DC12V voltages gas can such as be used
Pump, and in the control circuit of vehicle, set a relay to be connected with the EAP Electronic Air Pump, so as to facilitate driver according to weather condition
Pass through the startup or closing of Control air pump.
Certainly, the arrival end of airway tube can also be connected with the air pump carried on automobile, be given using the air pump of vehicle self-carrying
Camera provides air-flow.In order to control vehicle self-carrying air pump, air valve can be provided with the junction of air pump and airway tube, for controlling
The gas of air pump processed is for disconnected.
The embodiment of the present application is blown by using a source of the gas to cam lens position with certain pressure, and guarantee falls imaging
Raindrop on head are walked with the rainwater flowed on camera by air-blowing, and the camera can installed in left and right position of rear view mirror is in rain
Its normal work, driver clearly judge road conditions, installed in reversing when driving the rainy day in the image that can be gathered from camera
On camera, reversing observation image also not have impact on by rainwater.
When carrying out compliance test result to the device of the application, surface of camera head region is flowed through by using solid stream of water and surveyed
Examination, surface of camera head is blowed to the air pump of 5L/min tolerance, water droplet can not retain, image completely can with normal acquisition, and even if
Rainstorm weather (meteorology refers to 24 hourly rainfall depths more than 250mm), this rainfall is also not reaching to water when small area measures
Degree of the stream as noted (solid stream of water), therefore can also ensure removing cam lens surface rain water completely even in rainstorm weather
Effect.
It is described above, only it is present pre-ferred embodiments, any formal limitation not is made to the present invention.Although
The present invention is disclosed above with preferred embodiment, but is not limited to the present invention.Any those skilled in the art,
Without departing from the scope of the technical proposal of the invention, all using the methods and technical content of the disclosure above to the technology of the present invention
Scheme makes many possible changes and modifications, or is revised as the equivalent embodiment of equivalent variations.Therefore, it is every without departing from this hair
The content of bright technical scheme, the technical spirit according to the present invention is to any simple modification made for any of the above embodiments, equivalent variations
And modification, still fall within technical solution of the present invention protection in the range of.
