Abstract
The invention relates to a passive safety protection device in the automobile manufacturing field. An automobile bumper internally provided with multiple buffer and energy-absorbing barriers comprises a built-in bumper tyre, a buffer and energy-absorbing liner, strengthening brackets, fasteners and a peripheral plate, wherein the built-in bumper tyre is internally provided with the buffer and energy-absorbing liner and consists of an upper housing, a lower housing and a plurality of stayed poles; the buffer and energy-absorbing liner is made of aluminum alloy ultrathin sheets, in a regular hexagon honeycomb shape, and mounted in the middle of the built-in bumper tyre; the built-in bumper tyre is fixed on an automobile chassis steel beam by the strengthening brackets to form a complete stress structure; and the stress structure integrally assumes tasks of transfer, buffer, absorption and energy release. According to the automobile bumper, limited zone spaces at the front and rear ends of an automobile are used fully in overall design, the layout is precise, multiple buffer and energy-absorbing zones are reserved, all parts are tightly locked and fastened mutually, and the aluminum buffer and energy-absorbing liner is large in surface area and rapid in energy release. The automobile bumper has the advantages that the automobile bumper is convenient to process and mount, stable in structure and high in generality.
