The thickness of the S-shaped plate surfaces of the two wind deflectors 3 and 4 is gradually reduced from the bottom end to the top end.

In the first embodiment, although the automobile is buffered by the spring after impacting the first wind shield 3 or the second wind shield 4 at the moment of an accident, the probability that the automobile vertically impacts the wind shield is very small when the automobile is in the accident, while in the first embodiment, a good buffering effect can be achieved only when the automobile vertically impacts, and the automobile often obliquely impacts the wind shield at the moment of the accident; in addition, the wind shield is only provided with a recess to weaken the cross wind, and the wind shield effect is not ideal. In view of the above disadvantages, in this embodiment, the inclined design of the first guide post 301 and the second guide post 401 as the spring guide posts is added, and the split design of the wind deflectors 3 and 4 and the arrangement and the differential size design of the dimples are added to buffer and decelerate the cross wind for many times. Specifically, the specific working process and principle of the second embodiment are as follows:

when the automobile obliquely impacts the first wind deflector 3 or the second wind deflector 4, because a straight line formed by connecting the first guide post 301 and the second guide post 401 and a straight line in the normal running direction of the automobile form a non-vertical acute angle, after the automobile impacts the wind deflector, the springs on the first or second guide posts 301 and 401 can be better stressed, and therefore the damping effect is maximized. In addition, in the normal driving direction of a vertical automobile, the first wind shield 3 and the second wind shield 4 are completely aligned, so that the two wind shields are not staggered, cross wind in the extending direction of the vertical road can be protected powerfully, and the inclined design of the guide post between the two wind shields is adopted, so that the automobile impact force is absorbed as far as possible vertically, the inclined design of the wind shields is avoided, and the blocking effect of the cross wind is guaranteed simultaneously.

The recess 6 is the bowl type, and half the wind-break portion down 6 bores of recess are less than half wind-break portion 6 bores of recess, so set up, are convenient for improve half the ability of wind-break portion diffusion cross wind down to make cross wind can mostly be diffused when tentatively contacting the deep bead, cross wind blows to during deep bead 3,4, half wind-break portion down carries out preliminary buffering to wind-force earlier, makes the cross wind along half the wind-break portion upwards overturns down, simultaneously half the wind-break portion surface down 6 can make the cross wind scattered, thereby reduces wind-force, wind-force quilt can upwards overturn after half the wind-break portion shelters from, thereby follow the arcwall face of half the wind-break portion continues to move forward, the cross wind pass through during half the wind-break portion, can by on half the wind-break portion the recess disperses once more, thereby makes the wind-force through the road surface reduce greatly.

Wherein the whole wind screen face that is the center of half wind-break portion down makes a plurality of recesses 6 on its face outside wind-force is dispersed and is weakened, change the wind function to the sunken form design of the edge gradual change arch take the altitude, can also make a plurality of recesses 6 of half wind-break portion down wholly be the bowl form to further strengthen the dispersion to wind-force. In addition, in order to further enhance the resistance of the wind deflector to cross wind, the elastic detachable design of a magic tape or an elastic adhesive layer is adopted between the surface of the recess 6 and the bottom plate surface of the lower half wind deflector and the bottom plate surface of the upper half wind deflector, so that when the wind power is large, the surface of the recess 6, the lower half wind deflector and the bottom plate surface of the upper half wind deflector are relatively compressed and deformed to absorb the cross wind power, and the elastic detachable design can ensure the connection strength between the surface of the recess 6 and the bottom plate surface, and can simplify the design process and the subsequent assembly difficulty of the recess 6, because of the separate design, the design of the surface with the recess 6 is simpler, and during the subsequent assembly, the surface of the bottom plate of the lower half wind deflector and the upper half wind deflector can be installed in place, and then the surface of the recess 6 is installed, greatly reducing the installation difficulty.

The lower half wind shield part and the upper half wind shield part are in smooth transition integrated design, so that the rigidity of the whole structure of the wind shield is greatly enhanced. In addition, because the wind power of the upper half wind shielding part is primarily slowed down in the lower half part, the probability that the vehicle impacts the lower half part of the wind shielding plate is high, the bottom end of the lower half wind shielding part is adopted until the plate surface between the top ends of the upper half wind shielding part is gradually thickened, the whole quality can be lightened while the balance of the whole wind resistance strength of the lower half wind shielding part and the upper half wind shielding part and the impact resistance performance are ensured, and the cost is reduced.

In addition in the first embodiment, the car strikes behind the deep bead, can continuously slide forward at automobile shock absorber's in-process, strike a plurality of deep beads in proper order, and deep bead 3 in the second embodiment, 4 the whole sunken form design that is the center to edge gradual change arch take the altitude, can realize for the straight design in the first embodiment, increase the sliding contact distance of single deep bead and car, the arc of sunken form face itself can further increase the deformation space of deep bead self behind the car striking, with near further reinforcing crashproof ability, and the car is behind the arc face that strikes the deep bead, reduce directly to be rebounded and cause the probability of secondary damage, the increase car can be along the probability that arc rounding off face slided forward.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
