Abstract
The invention relates to an automobile bumper. The automobile bumper comprises a front face plate, a rear face plate, an upper web plate and a lower web plate. The front face plate, the rear face plate, the upper web plate and the lower web plate are connected with one another to form a bumper body with a closed cavity. A first connecting plate is arranged on the inner side wall face, opposite to the rear face plate, of the front face plate; a second connecting plate is arranged on the inner side wall face, opposite to the front face plate, of the rear face plate; elastic components are arranged between the first connecting plate and the second connecting plate at intervals. The automobile bumper is small in overall weight, and meanwhile capable of ensuring the safety.
Description
Technical field
The present invention relates to the protective device on a kind of car body, be specifically related to Federal bumper.
Background technology
At present, be arranged on the bumper/spoiler on car body etc., be the angular member bearing the bending load effect produced by external force, be made up of thin-walled material.This bumper/spoiler adopts the steel plate of such as 980MPa level carry out shaping thus formed.
The Main Function of bumper/spoiler deforms when being collision, to absorb energy, simultaneously by shock load curb girder transmission to the left and right, curb girder be out of shape, thus absorb energy when colliding.That is, by making energy when curb girder distortion, absorption collision, thus can suppress the distortion of car compartment according to designing requirement, occupant is from impact in protection.The weight of the bumper/spoiler of current use is large, if made by bumper/spoiler hollow, again reduces safety, therefore, how its safety can be made again to be guaranteed when reducing bumper/spoiler weight, be at present faced by problem.
Summary of the invention
For above-mentioned technical matters, the invention provides a kind of Federal bumper, the present invention has overall weight gently, simultaneously can guarantee its safety.
A kind of Federal bumper, comprise front panel, rear panel, epiplastron and bottom web, front panel, rear panel, epiplastron and bottom web are interconnected and form the bumper body that has closed cavity, front panel be provided with the first connecting panel relative to the interior sidewall surface of rear panel, rear panel be provided with the second connecting panel relative to the interior sidewall surface of front panel, between the first connecting panel and the second connecting panel, be arranged at intervals with elastomeric element.
Have employed such scheme, the present invention is interconnected and form the bumper body that has closed cavity by front panel, rear panel, epiplastron and bottom web, and have the bumper body of closed cavity, its weight is alleviated.Front panel be provided with the first connecting panel relative to the interior sidewall surface of rear panel, when bumper/spoiler is collided, first colliding forces acts on front panel, owing to front panel being provided with the first connecting panel, rear panel be provided with the second connecting panel relative to the interior sidewall surface of front panel, between the first connecting panel and the second connecting panel, be arranged at intervals with elastomeric element.Like this, colliding forces is by being delivered to elastomeric element after the first connecting panel dispersion, by transmitting rear second connecting panel after the buffering of elastomeric element, by the second connecting panel again to after colliding forces dispersion, be delivered to rear panel, after colliding forces being disperseed by dispersion several times like this, the application force being delivered to rear panel greatly reduces, and the colliding forces be finally delivered on car body also reduces greatly, therefore, the present invention is when weight saving, and its safety have also been obtained guarantee.
Be provided with packed layer in the closed cavity of described bumper body, elastomeric element wraps up by this packed layer.By the effect of packed layer, enhance the intensity of bumper/spoiler, because packed layer is made up of isocyanurate foam, therefore, packed layer can not have an impact to the weight of bumper/spoiler.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is the section-drawing along A-A line in Fig. 1;
1 is front panel, and 2 is rear panel, and 3 is epiplastron, and 4 is bottom web, and 5 is the first connecting panel, and 6 is the second connecting panel, and 7 is elastomeric element, and 8 is packed layer.
Detailed description of the invention
See figures.1.and.2, a kind of Federal bumper of the present invention, comprises front panel 1, rear panel 2, epiplastron 3 and bottom web 4, and front panel 1, rear panel 2, epiplastron 3 and bottom web 4 are interconnected and form the bumper body that has closed cavity.Front panel 1 be provided with the first connecting panel 5 relative to the interior sidewall surface of rear panel, rear panel 2 be provided with the second connecting panel 6 relative to the interior sidewall surface of front panel.Between the first connecting panel 5 and the second connecting panel 6, be arranged at intervals with elastomeric element 7, described elastomeric element 7 is spring.Be provided with packed layer 8 in the closed cavity of described bumper body, elastomeric element wraps up by this packed layer 8.Described packed layer is the packed layer that isocyanurate foam is formed.
Claims (4)
1. a Federal bumper, comprise front panel, rear panel, epiplastron and bottom web, front panel, rear panel, epiplastron and bottom web are interconnected and form the bumper body that has closed cavity, it is characterized in that, front panel be provided with the first connecting panel relative to the interior sidewall surface of rear panel, rear panel be provided with the second connecting panel relative to the interior sidewall surface of front panel, between the first connecting panel and the second connecting panel, be arranged at intervals with elastomeric element.
2. Federal bumper according to claim 1, is characterized in that, is provided with packed layer in the closed cavity of described bumper body, and elastomeric element wraps up by this packed layer.
