Background technology
Federal bumper is the safety device absorbing and slow down foreign impacts power, protection vehicle body front and rear part.Automobile front/rear collision bumper becomes channel-section steel with steel plate punched before many years, rivets or weld together with chassis side rail, has one section of larger gap, look very unsightly with vehicle body.Along with the development of auto-industry and engineering plastics are in the extensive application of auto-industry, Federal bumper has also moved towards as a kind of important safety device the road reformed.But; impulsive contact force suffered when front/rear collision bumper most at present is just clashed into by cushioned material layer absorption; the power that such bumper/spoiler can bear is limited, thus is also restricted the protection of automobile, if when every day use; just there is a kind of outside prestress in bumper/spoiler; when colliding, prestress just can offset a part of impact, thus improves the power that bumper/spoiler can bear; for this reason, a kind of prestress Federal bumper is proposed.
Utility model content
The purpose of this utility model is to provide a kind of prestress Federal bumper, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of prestress Federal bumper, comprise fore shell and side shell, the both sides of described fore shell are one-body molded side shell, the inside of described fore shell is provided with cavity, and cave in laterally in the middle part of cavity, the both sides of described cavity are installed with anchor fitting respectively, the inside of described cavity is provided with the first elastic stretching part, and the two ends of the first elastic stretching part are hinged with the anchor fitting of the both sides of cavity respectively, the inner homogeneous of described cavity is distributed with elastic supporting member for supporting optical member, described side shell is arc, the inner side of described side shell is installed with the second elastic stretching part, and the structure of the second elastic stretching part is identical with the first elastic stretching part.
Preferably, described anchor fitting comprises fixed end and coupling end, described fixed end and coupling end one-body molded, and the sidewall of fixed end is provided with hangnail.
Preferably, described first elastic stretching part comprises negative pressure shell and pull bar, and the two ends of institute's negative pressure shell are interspersed with pull bar respectively, and pull bar forms negative pressure cavity to two side stretchings.
Preferably, described elastic supporting member for supporting optical member comprises rubber drain pan, " work " word Rubber Parts and elastic component, the inner chamber of described rubber drain pan and the lower end clamping of " work " word Rubber Parts, and between the lower end of the inner chamber bottom of rubber drain pan and " work " word Rubber Parts, elastic component is installed.
Preferably, described elastic component is air bellow or coil spring.
Compared with prior art, the beneficial effects of the utility model are: the utility model is stretched in the middle of fore shell two side direction of bumper/spoiler by the first elastic stretching part, its middle forward end and rear end distortion are given prominence to, thus a kind of prestress is provided, stretched to centre by the side shell of the second elastic stretching part by bumper/spoiler, make its middle forward end distortion outstanding, thus a kind of prestress is provided, when colliding, prestress just can offset a part of impact, thus improves the power that bumper/spoiler can bear.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
