Self adaptation fall resistance illuminated grid
Art
The present invention relates to vehicle electronic device field, especially, be a kind of self adaptation on vehicle fall resistance illuminated grid.
Background technology
When automobile is advanced, air-flow enters radiator and then cooling electromotor through the middle grid of automobile, but the air entering electromotor also result in air drag, in entering along with the increase of speed, the air-flow of grid is the most, resistance is the biggest, and air flow rate now has substantially exceeded the throughput needed for the heat radiation of radiator.In Tong Shi, grid typically has the angle vertical with the high velocity air entered, and what i.e. air-flow was vertical bangs into middle grid, cause air drag bigger.
Under driving at night state, general automobile has two kinds of i.e. dipped beams of lighting system and distance light, and automobile is when advancing night, and speed is the fastest, and that light shines journey demand is the most remote.
Summary of the invention
In order to solve the problems referred to above, it is an object of the invention to provide a kind of self adaptation fall resistance illuminated grid, this self adaptation fall resistance illuminated grid can reduce car resistance and have the illumination of self adaptation speed at night.
The technical solution adopted for the present invention to solve the technical problems is:
This self adaptation fall resistance illuminated grid includes grid and light source, described grid two ends are narrow shortens pivot ear into, described pivot ear connects the drive shaft of a driver, described driver is electrically connected according to the control module of the speed described drive shaft turns angle of control with one, each described grid is parallel to each other and is arranged in grid by high order is stair-stepping, the downside of described grid is provided with the described light source that light is projected to described grid, described grid is provided with reflecting coating in the face of the side of described light source, described control module is according to swinging and lower swinging on the height of speed and the low reflecting coating side controlling described grid respectively.
As preferably, described driver is provided with the speed change component of described pivot ear high speed rotating, and described grid is equipped with cleaning shower nozzle.
As preferably, a low side of described grid extends horizontally to the felling tilted.
As preferably, described grid is separately positioned on the position of the former car light in headstock both sides, and the rear side of described grid is provided with the Y-shaped passage that the air-flow through grid leads to radiator.
The advantage of invention is:
nullDescribed control module is when vehicle is in low speed,Control swinging under the reflecting coating side of described grid,The light making described reflecting coating reflect is in dipped beam state and is suitable for low speed illumination,Owing to vehicle is in lower-speed state,Air velocity is slower,Therefore the bottom of grid reflecting coating side makes the gap between grid increase,Described radiator is made to have enough air-flows to dispel the heat,Described control module is when vehicle is in high speed,Control swinging on the reflecting coating side of described grid,The light making described reflecting coating reflect is in high-beam condition and is suitable for illumination at a high speed,Owing to vehicle is in fast state,Air velocity is very fast,Therefore the bottom of grid reflecting coating side makes the gap between grid reduce,Reduce the air-flow active force to described grid,Whole device is when night running,Control module can be used simultaneously to realize high speed distance light and to reduce grid ventilation,Low speed dipped beam increases grid ventilation.

Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings:
In the present embodiment, refering to Fig. 1, this self adaptation fall resistance illuminated grid includes grid 110 and light source 120, described grid 110 two ends are narrow shortens pivot ear 130 into, described pivot ear 130 connects the drive shaft of a driver, described driver is electrically connected according to the control module of the speed described drive shaft turns angle of control with one, each described grid 110 is parallel to each other and is arranged in grid 100 by high order is stair-stepping, the downside of described grid 100 is provided with the described light source 120 that light is projected to described grid 100, described grid 110 is provided with reflecting coating in the face of the side of described light source 120, described control module is according to swinging and lower swinging on the height of speed and the low reflecting coating side controlling described grid 110 respectively.
Above-mentioned self adaptation fall resistance illuminated grid, described driver is provided with the speed change component of described pivot ear 130 high speed rotating, described grid is equipped with cleaning shower nozzle, driving by described driver, described grid 110 can high speed rotating, the dirt in grid 110 can centrifugal force and clean shower nozzle water spray synergy under throw away.
Above-mentioned self adaptation fall resistance illuminated grid, a low side of described grid 110 extends horizontally to the felling tilted, make grid 110 under vehicle lower-speed state, reduce the amount of keeping out the wind of windward side, grid 110 is under vehicle high-speed state simultaneously, make the grid 100 can not be of completely closed, it is provided that the air quantity needed for the minimum heat radiation of vehicle.
Refering to Fig. 3, described grid 100 is separately positioned on the position of the former car light in headstock 400 both sides, the rear side of described grid 100 is provided with the Y-shaped passage 200 that the air-flow through grid 100 leads to radiator 300, it is distributed in headstock 400 both sides, owing to headstock both sides are arc, therefore, the angle that air-flow enters is not vertical with the position of grid 100, reduce the gas-flow resistance suffered by grid, simultaneously, the fraction being blocked in outside grid 100 is easier to spread to headstock both sides, reduces gas-flow resistance further.
The working method of above-mentioned self adaptation fall resistance illuminated grid:
nullRefering to Fig. 2,Described control module is when vehicle is in low speed,Control swinging under the reflecting coating side of described grid 110,The light making described reflecting coating reflect is in dipped beam state and is suitable for low speed illumination,Owing to vehicle is in lower-speed state,Air velocity is slower,Therefore the bottom of grid 110 reflecting coating side makes the gap between grid 110 increase,Described radiator 300 is made to have enough air-flows to dispel the heat,Refering to Fig. 1,Described control module is when vehicle is in high speed,Control swinging on the reflecting coating side of described grid 110,The light making described reflecting coating reflect is in high-beam condition and is suitable for illumination at a high speed,Owing to vehicle is in fast state,Air velocity is very fast,Therefore the bottom of grid 110 reflecting coating side makes the gap between grid 110 reduce,Reduce the air-flow active force to described grid 110.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
