The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Fig. 1-the 3rd, the structural representation of the crumple formula hinge of engine compartment cover.
A kind of crumple formula hinge for engine compartment cover comprises rocker bar bearing 1 and hinge rocking arm 2, and described hinge rocking arm 2 flexibly connects by bearing pin and described rocker bar bearing 1, and described hinge rocking arm 2 can be around described rocker bar bearing 1 rotation.
Described hinge rocking arm 2 comprises fixed head 21 and arc pendulum rod 22, and described fixed head 21 is fixedlyed connected with lid, and described lid can be the hatchcover of motor, also can be the other types lid of demand pooling feature.Has the slotted hole 23 of adjusting on the described fixed head 21, described adjusting slotted hole 23 both sides are provided with second fixing hole 24, described second fixing hole 24 is used for fixedlying connected of described fixed head 21 and described lid, described adjusting slotted hole 23 is for the fixedly connected process of described fixed head 21 with described lid, if described second fixing hole 24 is inconsistent with the screwed hole position on the described lid, can suitably regulate by described adjusting slotted hole 23.Described arc pendulum rod 22 has cushioning effect, can with bending side 14 reasonably combined formation two-stage buffer gears, buffering effect is obvious, can prevent effectively that hatchcover from closing the distortion close in the process.
Described rocker bar bearing 1 comprises collapsing structure 11, holder 12 and junction plate 13.One end of described collapsing structure 11 links to each other with holder 12, and its other end links to each other with junction plate 13, can produce plastic strain when collision takes place.Described holder 12 bottoms are provided with groove 18, and described groove 18 both sides are provided with first fixing hole 19, and described first fixing hole 19 is used for fixedlying connected of described rocker bar bearing 1 and above-mentioned motor place body of a motor car.
Fig. 4-the 7th, the structural representation of rocker bar bearing 1.
Described rocker bar bearing 1 comprises collapsing structure 11, holder 12 and junction plate 13.Plane, described junction plate 13 place is perpendicular to plane, described rocker bar bearing 1 place, its middle part is provided with pan 16, described collapsing structure 11 is provided with edge strengthening plate 20 with the junction of described holder 12, and edge strengthening plate 20 ruptures for the junction that prevents described collapsing structure 11 and described holder 12.
