Abstract

The utility model relates to a W-shaped bumper framework, which relates to the technical field of bumpers and resolves technical problems that common bumper frameworks with U-shaped sections only can absorb portions of impact energy when being impacted, bumpers have poor bearing capacity, and then front impact capacity of automobiles is limited, or the bumper frameworks are heavier to increase bearing capacity of the bumpers, thereby increasing weight of the automobiles. The main body of the W-shaped bumper framework is arc-shaped roughly. The W-shaped bumper framework is characterized in that the section of the framework is roughly W-shaped. The principle includes that the W-shaped bumper framework absorbs impact energy by aid of collapse deformation of the W-shaped structure, thereby strengthening bearing capacity of the bumper, improving automobile front impact property, and then being capable of properly lightening weight of the bumper and the automobile body.

Description

A kind of W type Federal bumper skeleton
Technical field:
The utility model relates to a kind of Federal bumper skeleton, specifically a kind of W type Federal bumper skeleton.
Background technology:
Federal bumper is when collision happens, absorbs the foreign impacts power that relaxes, the safety device of protection vehicle body front and rear part.Especially in the automobile low speed collision, bumper/spoiler plays crucial effects to the crash survivability of automobile.The bumper/spoiler skeleton then is the main load parts of bumper/spoiler safety precaution, and the load-carrying capacity of bumper/spoiler is had significant impact.But common U type cross section bumper/spoiler skeleton when collision happens, can only absorb the fraction collision energy, and the bumper/spoiler load-carrying capacity is poor, and the head-on crash ability of automobile is weakened; Perhaps thicken in order to increase the bumper/spoiler load-carrying capacity, overstriking bumper/spoiler skeleton, thereby car weight is increased, cause the waste of the material and the energy.
Summary of the invention:
The utility model is in order to overcome the shortcoming of existing U type bumper/spoiler skeleton, a kind of W type Federal bumper skeleton of proposition.This W type skeleton can absorb more collision energy than U type skeleton under identical materials and weight, have better load-carrying capacity, improves frontal crash of vehicles characteristic and safety.
The scheme that realizes above-mentioned purpose is: a kind of W type Federal bumper skeleton, main body is roughly curved, it is characterized in that the cross section of skeleton is the approximate W type.
When automobile bumped, W type bumper/spoiler skeleton can utilize the conquassation of W type structure to be out of shape to absorb more collision energy, relaxed impact process, and the load-carrying capacity of bumper/spoiler is strengthened, and can resist stronger impact, thereby improve the crash-worthiness and the safety of automobile.Under identical collision performance required, W type bumper/spoiler skeleton can be saved the certain material and the energy.
Description of drawings:
Fig. 1 is the graphics of W type Federal bumper skeleton;
Fig. 2 is the front view of W type Federal bumper skeleton;
Fig. 3 is the cutaway view of W type Federal bumper skeleton.
Among the figure:
The 1-lateral wall
The specific embodiment:
Be that example is described in further detail with the bumper/spoiler skeleton shown in the accompanying drawing below.
As illustrated in fig. 1 and 2, W type Federal bumper skeleton is roughly curved at length direction, and middle high two ends are low; As shown in Figure 3, the cross section of bumper/spoiler skeleton is approximately W type and its structure about the longitudinal plane of symmetry symmetry, and two lateral walls in cross section and the angle of longitudinal plane of symmetry are selected between 0 to 45 degree as required.When the bumper/spoiler skeleton withstands shocks power, be out of shape by the conquassation of W type structure and absorb collision energy, reach and relax the purpose of impacting, effectively improve the head-on crash characteristic of automobile.

Claims (3)

1. W type Federal bumper skeleton, it is characterized in that: the cross section of skeleton is the approximate W type.
2. a kind of W type Federal bumper skeleton according to claim 1, it is characterized in that: W type cross section is about frame center's face left-right symmetric.
3. a kind of W type Federal bumper skeleton according to claim 2 is characterized in that: the angle of the lateral wall of skeleton (1) and frame center's face is between 0 to 45 degree.
