Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: see Fig. 1, Fig. 2, a kind of pedestrian safety system, comprises safety air bag 1, gas generator 2, vision sensor 3 and controller; Described safety air bag 1 is connected with gas generator 2, and described gas generator 2 is all connected with controller with vision sensor 3, and described controller is ripe prior art, and it can control gas generator 2 and ignite after receiving vision sensor 3 signal; As a kind of embodiment, this controller comprises signal comparator circuit and trigger control circuit, when the hypotelorism that vision sensor 3 monitors, the electric signal sent to controller is also larger, when this electric signal is greater than the value of electrical signals preset in signal comparator circuit, signal comparator circuit sends energizing signal to trigger circuit, after trigger control circuit receives energizing signal, send actuation signal to gas generator 2, thus gas generator 2 is ignited (namely gas generator 2 starts).Described vision sensor 3 is two, is installed near fog lamp place, headstock left and right (side that left and right fog lamp is adjacent) respectively; Because fog lamp position is lower, and be positioned at automobile foremost, monitoring effect thus can be made better, more effectively to protect pedestrian.
After described safety air bag 1 is folding, be located in airbag housing 4, concrete folding process is as follows: see Fig. 3, is first folded towards safety air bag 1 central cavity 11 junction of safety air bag 1 left and right sides 12 in sidepiece 12 and central cavity 11; Then on the symmetrical axle of central cavity 11, a point is found, make axis of symmetry upper and lower apart from equal, the air inlet pipe 13 of central cavity 11 lower surface is arranged near this point simultaneously, and the upper and lower of central cavity 11 is respectively towards this some winding, and air inlet pipe 13 does not participate in folding.This airbag housing 4 is installed between headstock bumper/spoiler and (vehicle frame) water tank upper beam 6, and is positioned at above headstock bumper/spoiler; The front side of described airbag housing 4 is open sides, and on front side of headstock bumper skin 5 and air bag, correspondence position is plastics (line of weakness) structure; Wherein, bumper/spoiler is close in the downside of airbag housing 4.Have an air inlet pipe 13 in the center of the lower surface of safety air bag 1 central cavity 11, this air inlet pipe 13 is inlet end away from one end of central cavity 11; The inlet end of described air inlet pipe 13 is fixedly connected with bottom airbag housing 4 by mounting seat, and bottom airbag housing 4, the position of the inlet end of corresponding air inlet pipe 13 has induction opening; Described gas generator 2 to be installed on the downside of airbag housing 4 and to be fixedly connected with airbag housing 4, and the induction opening of its air extractor duct and airbag housing 4 is just right, can be inflated by this gas generator 2 to safety air bag 1.
Described safety air bag 1 and airbag housing 4 are all in the arc consistent with headstock bumper/spoiler, wherein, described safety air bag 1 comprises central cavity 11 and is positioned at two sidepieces 12 at central cavity 11 two ends, and after safety air bag 1 is inflated, corresponding Der Scheinwerfer mit FernlichtAbblendlichtStandlicht position forms breach; Make the parcel of safety air bag 1 pair of headstock better, can pedestrian be avoided better injured.
The upper side of the central cavity 11 of described safety air bag 1 is connected by elastic woven tape 14 with the middle part of downside, described elastic woven tape 14 is in the arc consistent with central cavity 11, make the shape of upper and lower surface tension formation mat during airbag aeration, prevent people from sliding from air bag; Elastic woven tape 14 is provided with some air extractor vents; Be convenient to gas circulation, thus air bag fast aeration is launched.
After described safety air bag 1 is inflated, its central cavity 11 can cover the region between the headlight of headstock left and right, and can extend upwardly to point suture place of bumper skin 5 and engine case 7, and the left and right sides 12 of safety air bag 1 can cover the region above headlight; Thus do not cause blocking illumination after safety air bag 1 is launched.
See Fig. 4; when sensor detects that automobile soon bumps against pedestrian; signal is passed to controller by vision sensor 3; controller sends actuation signal according to signal to gas generator 2; gas generator 2 is ignited, and then safety air bag 1 is inflated, and makes safety air bag 1 break through plastics (line of weakness) structure of bumper skin 5; cover in bumper/spoiler and car bonnet seam, produce the effect of protection pedestrian.
Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present utility model.
