Description

A kind of flow-guiding board of vehicle

Technical field

The utility model belongs to technical field of automobile parts, relates to a kind of flow-guiding board of vehicle.

Background technology

Quickening along with growth in the living standard and rhythm of life, automobile has become the vehicle indispensable in life, when automobile is extensively universal, people also have higher requirement to the performance of automobile, as the frequent speed per hour of Modern Car has reached 100 kilometers of left and right, F-Zero more reaches more than 200 kilometers, therefore the body drawing of car should be obeyed aerodynamics, there is the sky resistance coefficient of trying one's best low, take measures again, at the front and back end of vehicle body mounting guiding board and spoiler, to guarantee the driving safety of car.On aerodynamics, have and experimental results show that the speed of air rate and pressure are inversely proportional to, that is to say that air rate is faster, pressure is less, on the contrary air rate is slower, and pressure is larger.If car external form is similar to wing shape of cross section, in running at high speed because the stream pressure of vehicle body upper and lower surface is different, below large little above, this difference of pressure will inevitably produce a kind of raising force, the faster difference of pressure of the speed of a motor vehicle is larger, raising force is also just larger.This raising force is also a kind of of air resistance, and automotive community is called induced drag, accounts for 7% of car load air resistance, although ratio is less, endangers very large.The lift producing when running at high speed in order to reduce car, automobile design teacher is except improving aspect car external form, vehicle body integral body is tilted to front lower place and on front-wheel, produce downward pressure, the tailstock is changed into short flat, the negative pressure that minimizing acts on from roof to rear portion and preventing that trailing wheel from floating, also below the bumper/spoiler of front end of car, load onto downward-sloping connecting panel, connecting panel and vehicle body front valance panel join together, centre has suitable ventilation inlet and adds air flow degree, lower car spirit and press, this connecting panel is called deflecting plate.

As Chinese invention patent application (application number: 200610099646.5) disclose a kind of for automobile, the guiding device of car particularly, be arranged on automobile tail, comprise a diversion member, this diversion member can move to a run location stretching out from dead position.In dead position, diversion member is integrated in the shape trend of afterbody.In order further to improve the output on aerodynamics property, the especially rear axle that starts described guiding device, designed diversion member has the larger horizontal expansion in the dead position (A) of retracting of a ratio in the run location stretching out (D).This guiding device has guide functions, but deflecting plate is to be directly fixed on car body, and the angle between itself and horizontal surface cannot change, and user cannot need to regulate the angle of deflecting plate according to self, and Applicable scope is less.
