Abstract
The utility model provides an aluminum alloy rear anti-collision cross beam and mounting frame assembly for an automobile, which comprises a rear anti-collision cross beam body and a mounting frame, wherein the rear anti-collision cross beam body is a bilaterally symmetrical arc-shaped structure formed through squeezing and bending processes, the cross section of the rear anti-collision cross beam body takes the shape that two parallel longitudinal beams are connected between upper and lower cross beams which are parallel to each other, and the aluminum alloy mounting frame takes the shape of the letter n and is connected to the two ends of the anti-collision cross beam body. In the utility model, the characteristics of light weight, high intensity, good impact resistance and matured squeezing and bending process of the aluminum alloy material are fully used, an original steel rear anti-collision cross beam is optimized and integrally designed to be an integral sectional material piece, the weight loss effect is obvious, and the safety performance and the energy-saving effect are improved certainly.
Description
Technical field
The utility model relates to a kind of rear anti-crash beam structure of automobile.
Background technology
Automobile rear anti-crash crossbeam and mounting bracket are as the buffer body that absorbs crash energy, and its crash-worthiness plays crucial effects in automotive safety when low speed collision.Aluminum alloy rear anti-crash crossbeam is compared with the crashproof crossbeam of steel can not only reach the weight-saving purpose, more can improve the energy absorbing in the collision process.
At present, common back anticollision crossbeam mainly is to adopt steel structure, and as shown in Figure 1, its rear anti-crash cross-beam body 1 by steel constitutes, and is linked on the car body by bolt at the two ends of rear anti-crash cross-beam body 1 then.These steel components form back anticollision crossbeam assembly by welding, general assembly again after punching press, its welding deformation is not easy control, poor dimensional stability, it is many to relate to operation, and technological process is long, production efficiency is low, and these parts all are steel parts, is unfavorable for realizing lightweight.
The utility model content
The purpose of this utility model is the above-mentioned many deficiencies at the prior art existence, proposing a kind of automobile makes up with aluminum alloy rear anti-crash crossbeam and mounting bracket, substitute the steel sheet metal component with an extruding bool, to solve welding deformation, the technical matters of size instability etc., the while can also alleviate the weight of rear anti-crash crossbeam.
The technical solution of the utility model is as follows:
A kind of automobile makes up with aluminum alloy rear anti-crash crossbeam and mounting bracket, and it comprises rear anti-crash cross-beam body, mounting bracket; The symmetrical arcuate structure of described rear anti-crash cross-beam body for being shaped by extruding and bending process, the cross sectional shape of described rear anti-crash cross-beam body is to connect two parallel longerons in the middle of two parallel crossbeams up and down, the aluminum alloy mounting bracket is " several " font, and it is connected the two ends of rear anti-crash cross-beam body.
The utility model has made full use of that aluminum alloy materials is in light weight, intensity is high and the characteristics of good impact resistance, extruding bending process maturation, former steel rear anti-crash crossbeam is optimized the integrated profile piece that is designed to integrative-structure, solve the technical matters of existing steel crossbeam welding deformation, size instability etc., and weight loss effect is obvious, and safety performance, energy-saving effect are improved.
Description of drawings
Fig. 1 is original steel rear anti-crash beam structure scheme drawing;
Fig. 2 is the utility model aluminum alloy rear anti-crash crossbeam and mounting bracket structural representation;
Fig. 3 is the C-C section-drawing of Fig. 1.
Among the figure, 1-steel rear anti-crash cross-beam body, 2-aluminum alloy rear anti-crash cross-beam body, 3-aluminum alloy mounting bracket; 21-crossbeam, the 22-longeron.
The specific embodiment
As shown in Figures 2 and 3, this structure adopts aluminum alloy rear anti-crash cross-beam body 2 and aluminum alloy mounting bracket 3 to form, and they are to adopt aluminium alloy extrusions to be shaped by extruding and bending process to obtain.The cross sectional shape of aluminum alloy rear anti-crash cross-beam body 2 is similar " well " font, and from the cross section, it is shaped as up and down and connects two parallel longerons 22 in the middle of two parallel crossbeams 21, and such structural strength height has saving in material.The aluminum alloy rear anti-crash is hit the left-right symmetric of cross-beam body 2 and is the class arc, and the collision crossbeam is approaching before its radian and the former steel, interferes with parts around the rear bumper etc. guaranteeing not.Aluminum alloy mounting bracket 3 is " several " font, and it is to pass through the mounting hole bolt together earlier to car body, and then is connected by the two ends of bolt with aluminum alloy rear anti-crash cross-beam body 2.
Be to guarantee the performance of aluminum alloy rear anti-crash crossbeam and mounting bracket thereof, the material four that this structure adopts carries out optimizing components on commercial aluminum alloy basis, and the content of copper is increased, and the tensile strength under its T6 state is strengthened, and stretch ratio makes moderate progress.Then, aluminium ingot is carried out uniformization handle, after the extrusion molding, utilize the method for pressure bending to carry out press shaping die, at last the crossbeam after being shaped is carried out ageing treatment, to improve its performance figure.
Claims (2)
1. an automobile makes up with aluminum alloy rear anti-crash crossbeam and mounting bracket, and it comprises rear anti-crash cross-beam body, mounting bracket; It is characterized in that: the symmetrical arcuate structure of described rear anti-crash cross-beam body for being shaped by extruding and bending process, the cross sectional shape of described rear anti-crash cross-beam body is to connect two parallel longerons in the middle of two parallel crossbeams up and down, the aluminum alloy mounting bracket is " several " font, and it is connected the two ends of rear anti-crash cross-beam body.
2. automobile according to claim 1 aluminum alloy rear anti-crash crossbeam, it is characterized in that: described aluminum alloy mounting bracket is to connect by bolt with being connected of rear anti-crash cross-beam body two ends.
