Description
Technical field
The present invention relates to automobile technical fields, more particularly to a kind of automobile windscreen rainproof system.
Background technique
Traditional vehicle wiper includes wiper and the windshield wiper blade that is mounted in wiper, windshield wiper blade and automotive windshield glass
Glass fitting, wiper drive windshield wiper blade to swing, and remove sleet and dirt on windshield.Traditional wiper is primarily present
Following disadvantage: (1) swinging will affect pilot's line of vision, and there are security risks；(2) windshield wiper blade rubs repeatedly to windshield
It wipes, damage windshield may scratch windshield when especially having sandstone on the windshield.
To solve the above-mentioned problems, Chinese utility model patent CN2186686 specification discloses a kind of motor vehicle driving
Jetting windscreen wiper immediately ahead of room on windshield, the jetting windscreen wiper by mounted in upper windscreen jet thrust and
The pipeline being connected to compressed gas source is constituted, and is gone out forced draft continuously from the puff prot of jet thrust, is wiped off with forced draft
Sleet on glass.
Although the program can solve the defect of traditional wiper to a certain extent, and traditional windscreen wiper
Device is the same, is cleared up after rainwater encounters glass, then to the rainwater on glass, and there are certain hysteresis quality, gears for cleaning
Rainwater on wind glass equally will affect the visual field of driving, also, be cleared up using jet thrust the sleet on glass, although
The air-flow of larger pressure can be generated, but the area of air-flow is small, can not windshield comprehensively be protected and be cleared up, effect
Fruit is unsatisfactory.
Summary of the invention
For the defects in the prior art, the present invention provides a kind of automobile windscreen rainproof system, to solve rainwater leaching
The unclear problem in the visual field caused by windshield.
The present invention provides a kind of automobile windscreen rainproof system, including fan assembly, the fan assembly includes: wind
Casing body, the Blower Housing are mounted in the headstock before shield glass, the rear portion of automobile front cover and Blower Housing
The rear portion of upper side body be horizontally arranged with air port, the upper side body for crossing air port and Blower Housing in automobile front cover
On cross air port be overlapped；Several high pressure blowers, the high pressure blower are mounted side by side in Blower Housing, the outlet air of each high pressure blower
Mouth crosses air port towards described, and the wind of each high pressure blower blowout forms one of strength wind in the front of shield glass
Wall.
Existing windscreen rainproof system is all the mode of " improvement " to solve the problems, such as windshield rainwater, it may be assumed that
Rainwater clears up the rainwater of windscreen surface after encountering windshield, and rainwater drenches on the windshield, even if timely
Cleaning, can also affect to the visual field, and the application solves asking for windshield rainwater by the way of " prevention "
Topic, it may be assumed that one of strength brattice is formed before shield glass by high pressure blower, when rainwater is close to strength brattice, meeting
It is blown afloat and be down the wind blown away by strength brattice, to make rainwater that can not encounter windshield, ensure that and get a clear view, thoroughly
It does not know in the visual field caused by solving the problems, such as rainwater leaching on windshield；Also, when blower works, it can accelerate
Air flowing in headstock, has taken into account the function of automobile engine and heat dissipation of water tank.
Further, the fan assembly further includes wind guide tank, and the cross section of the wind guide tank is in bar shaped, wind guide tank into
Wind end connects with the air outlet of each high pressure blower.Since brattice is cooperatively formed by multiple blowers, adjacent wind
There are wind-force weak areas between machine, by the way that wind guide tank is arranged, can integrate excessively to the wind of each blower blowout, make each region
Wind speed is uniform, by the guiding of wind guide tank, can reduce the diverging of air-flow, improve the EFFECTIVE RANGE of brattice.
Further, each high pressure blower coaxial arrangement, and be cascaded between each high pressure blower by connector
Combined fan is formed, the left and right both ends of the combined fan pass through shaft respectively and Blower Housing is rotatablely connected, and combined fan exists
