Flow-disturbing block is followed successively by diversion division along the headstock of vehicle body to tailstock direction, turning point and turbulent portion, during high vehicle speeds, wind passes through diversion division successively, turning point and turbulent portion, diversion division is taper, on diversion division to direction, turbulent portion, the width of diversion division is increased gradually by the narrow thickness that broadens, this design can slow down the flow velocity of wind and ensure that wind direction is steady, wind is separated along change, change the flow direction of wind, thus reduce the sound intensity of microscope base edge, reduce the aerodynamics noise produced between outside rear-view mirror and vehicle body, on turning point to direction, turbulent portion, the width in the turbulent portion thickness that narrows from the width reduces gradually, this design makes air-flow form cyclone in turbulent portion, the disorderly frequency in air current flow direction reduces, thus reduce the sound intensity of microscope base edge, reduce the aerodynamics noise between outside rear-view mirror and vehicle body.
In above-mentioned outside rear-view mirror structure, described flow-disturbing block sidewall slope and Width streamlining.
Flow-disturbing block sidewall slope and Width streamlining, when can ensure that air-flow flows through flow-disturbing block, air flow line changes and can not produce larger impulsive force to car body and affect the traveling of vehicle gently.
In above-mentioned outside rear-view mirror structure, described flow-disturbing block maximum height is of a size of 6 ~ 12mm, and the most wide degree is of a size of 10 ~ 20mm, and extreme length is of a size of 35 ~ 45mm.
The oversize of flow-disturbing block makes the spacing between flow-disturbing block and outside rear-view mirror too small and affects vehicle to travel, the poor effect of the undersized generation flow-disturbing of flow-disturbing block, so adopt the flow-disturbing block maximum height size of effect optimum to get 6 ~ 12mm, the widest width dimensions gets 10 ~ 20mm, and extreme length size gets 35 ~ 45mm.
In above-mentioned outside rear-view mirror structure, described flow-disturbing block and base adopt one machine-shaping.
Flow-disturbing block and the machine-shaping of base integrated injection molding, structure does not simply affect base processing technology.
Compared with prior art, the outside rear-view mirror structure of this vehicle has following advantage: reduce sound frequency by reducing wind speed thus reduce the noise produced when outside rear-view mirror is run at high speed, structure is simply processed fast.

Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, the outside rear-view mirror of usual vehicle comprises mirror body 1 and microscope base 2, described microscope base 2 comprises adapter plate 2b and connecting portion 2a, mirror body 1 is connected with adapter plate 2b by connecting portion 2a, adapter plate 2b to be connected on vehicle body and to be fitted and connected with vehicle body, adapter plate 2b has the flow-disturbing block 3 for changing gas flow rate, when vehicle travels, air-flow flows along bodywork length direction, when high vehicle speeds, air-flow is by between mirror body 1 and adapter plate 2b, due to flow-disturbing block 3 be streamline strip shape and flow-disturbing block 3 between mirror body 1 and adapter plate 2b, gas is flow through along flow-disturbing block 3 by air-flow during flow-disturbing block 3, the reduced velocity flow of air-flow, thus reduce the sound intensity of microscope base 2 edge, reduce the aerodynamics noise produced between outside rear-view mirror and vehicle body.
As shown in Figure 2, flow-disturbing block 3 is streamline strip shape, and the length direction of flow-disturbing block 3 is parallel with bodywork length direction, and air-flow is along the length direction of flow-disturbing block 3 through flow-disturbing block 3, and air flow line progressively changes, and can reach optimum flow-disturbing effect.
Flow-disturbing block 3 is followed successively by diversion division 3a along the headstock of vehicle body to tailstock direction, turning point 3b and turbulent portion 3c, during high vehicle speeds, wind is successively by diversion division 3a, turning point 3b and turbulent portion 3c, diversion division 3a is taper, diversion division is increased by the narrow thickness that broadens gradually by width on diversion division 3a to 3b direction, turning point, distinguished and admirable when crossing diversion division 3a the direction of wind change along with the direction of diversion division 3a, this design can slow down the flow velocity of wind and ensure that wind direction is steady, wind is separated along change, change the flow direction of wind, thus reduce the acoustic wave frequency of microscope base 2 edge, reduce the aerodynamics noise produced between outside rear-view mirror and vehicle body, turbulent flow portion 3c is reduced gradually by the thickness that narrows from the width of width on turning point 3b to 3c direction, turbulent portion, this design makes air-flow form cyclone at turbulent portion 3c, the disorderly frequency in air current flow direction reduces, thus reduce the sound intensity of microscope base 2 edge, reduce the aerodynamics noise between outside rear-view mirror and vehicle body.Flow-disturbing block 3 sidewall slope and Width streamlining, when can ensure that air-flow flows through flow-disturbing block 3, air flow line changes and can not produce larger impulsive force to car body and affect the traveling of vehicle gently.
The oversize of flow-disturbing block 3 makes the spacing between flow-disturbing block 3 and outside rear-view mirror too small and affects vehicle to travel, the undersized generation flow-disturbing poor effect of flow-disturbing block 3, so flow-disturbing block 3 maximum height size is got 9mm, the widest width dimensions gets 12mm, and extreme length size gets 38mm.
Flow-disturbing block 3 and the machine-shaping of base integrated injection molding, structure does not simply affect base processing technology.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
