Abstract
The invention discloses a rainproof device for a camera of a side rearview mirror. The rainproof device comprises the camera in the side rearview mirror, wherein a semi-sealed protective housing is arranged in front of the camera lens of the camera; a small hole is formed in the protective housing in a direction opposite to the camera lens. The system not only has an extremely good rainproof effect, but also has a simple structure, convenience in mounting, low cost and a great market application potential.
Description
Technical field
the invention belongs to monitored control system field, automobile side blind area, be specifically related to a kind of rearview mirror camera rain insensitive device.
Background technology
in driving procedure, be the important leverage of traffic safety by rearview mirror observation rear side vehicle and obstacle, but due to the restriction of body construction, blind area still cannot be avoided, for traffic safety has buried hidden danger.Driving today of ancillary technique develop rapidly, by installing camera in the back mirror of two, left and right, and be transferred in car on read-out by rear real-time imaging, chaufeur can be seen in the safe range of rear to be had clear or sends a car, thus eliminate sight line blind area, improve the safety factor of driving.
at present, this kind equipment has been widely used in blind area monitoring, reversing is assisted, park in the system such as auxiliary.But in application process, many problems are also following, and wherein one of problem is exactly that cam lens is easily stained with rainwater on rainy day, causes image fog, focal length variations, makes whole system function be close to paralysis.And traffic accident on rainy day is easily sent out, driving risk factor increases, and only resolves the problem that rainwater causes camera fuzzy, and this system just can be made to play larger effect.For this problem, industry technology personnel take multiple terms of settlement, relatively many is at cam lens film on surface, divide hydrophobic film and hydrophilic film two kinds, the feature of hydrophobic film is that water droplet is above just as the globule on lotus leaf, can form circular drop to slip rapidly, can not washmarking be formed, but domestic being difficult at present finds Reliable Products; Hydrophilic film then can make water form even water layer at face, but finds in actual test process or can there is focal length variations and image blurring problem, is difficult to reach the requirement of the closely-related automotive safety product with personal safety.
Summary of the invention
get wet for rainy day rearview mirror camera and the problem that cannot normally work, the present invention proposes a kind of rearview mirror camera rain insensitive device, utilize pinhole imaging system principle and the law of airflow, two-way waterproof object can be realized on the basis not affecting the collection of camera normal picture with pinhole imaging system device, Duct design by blocking at camera lens, a kind of new failure-free solution is provided for rearview mirror camera is rainproof, the function of whole side vision aid system can be made to obtain larger performance.
technical scheme of the present invention is: a kind of rearview mirror camera rain insensitive device, and comprise the camera arranged in rearview mirror, described cam lens front is provided with a semi-enclosed guard shield, and described guard shield is just provided with an aperture to lens direction.
further, be provided with air channel in described rearview mirror, the one end in described air channel connects guard shield, and the other end ventilation inlet in described air channel is arranged on the shell side of rearview mirror, and described ventilation inlet is just arranged vehicle heading.
further, described ventilation inlet is provided with air channel filter screen.
further, described air channel is " Ω " shape.
advantage of the present invention is:
1. this rain insensitive device utilizes pinhole imaging system principle and the law of airflow, two-way waterproof object can be realized on the basis not affecting the collection of camera normal picture with the Duct design of pinhole imaging system device, " Ω " shape by blocking at camera lens, a kind of new failure-free solution is provided for rearview mirror camera is rainproof, the function of whole side vision aid system can be made to obtain larger performance.
2. this system not only has splendid rainproof effect, and structure is simple, easy for installation, with low cost, has very large market application potential.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the invention will be further described:
fig. 1 is the structural representation of a kind of rearview mirror camera rain insensitive device in the present invention;
fig. 2 is the cutaway view of a kind of rearview mirror camera rain insensitive device in the present invention.
wherein: 10, rearview mirror, 11, camera, 12, camera lens, 13, guard shield, 14, aperture, 15, air channel, 16, casing of rearview mirror, 17, air channel filter screen, 18, ventilation inlet.
Detailed description of the invention
for making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with detailed description of the invention also with reference to accompanying drawing, the present invention is described in more detail.Should be appreciated that, these describe just exemplary, and do not really want to limit the scope of the invention.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present invention.
embodiment:
below in conjunction with accompanying drawing, preferred embodiment of the present invention is described further.
as Fig. 1, shown in Fig. 2, a kind of rearview mirror camera rain insensitive device of the present invention, comprise the camera 11 being arranged on rearview mirror 10 inside, this rain insensitive device comprises cam lens and blocks and pinhole imaging system device, namely a semi-enclosed guard shield 13 is set in the front of the camera lens 12 of camera 11, guard shield 13 just there is an aperture 14 to the position in direction with camera lens 12, this guard shield 13 can stop camera lens 12 and contacting rain water, aperture size suitably adjusts according to imaging requirements and camera lens specification with apart from distance of camera lens, according to pinhole imaging system principle, camera lens 12 still can photograph outside vehicle and blind area situation by this aperture 14.
in order to increase rainproof effect further, the air channel 15 be connected with guard shield 13 is provided with in rearview mirror 10, the ventilation inlet 18 in air channel 15 is arranged on casing of rearview mirror 16 side, ventilation inlet 18 is just arranged vehicle heading, the shape in air channel 15 is preferably " Ω " shape, the object of this profile design is that the rainwater making to enter from ventilation inlet 18 gets off because of the stop landing of gravity or inner vertical walls, prevents rainwater from entering guard shield 13 from ventilation inlet 18 inner.
the air channel filter screen 17 stopping that large granular impurity enters further is provided with at air inlet of air duct 18 place, when the vehicle is running, air flows to reversing sense the wind formed can be inner from ventilation inlet 15 access to plant, and blow out from aperture 14, the rainwater in around aperture and front is dispelled, prevent rainwater from entering from aperture, aperture is kept clear, realize two-way waterproof (in figure, the direction of arrow is the flow direction of wind).
this rain insensitive device can solve current rearview mirror camera and be stained with rain and the problem that cannot normally work, and makes the function of whole side vision aid system obtain larger performance.
this device not only has splendid rainproof effect, and device is simple, and easy for installation, cost is low, has very large market application potential.
should be understood that, above-mentioned detailed description of the invention of the present invention only for exemplary illustration or explain principle of the present invention, and is not construed as limiting the invention.Therefore, any amendment made when without departing from the spirit and scope of the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.In addition, claims of the present invention be intended to contain fall into claims scope and border or this scope and border equivalents in whole change and modification.
