Abstract

The utility model provides an automobile cross beam structure. The cross section of a cross beam body is U-shaped and a trapezoid bend is arranged at the middle section. The improvement is that each of left and right bending parts of the trapezoid bend of a cross beam is provided with a reinforcing block; the shape of the reinforcing block is the same as those of corresponding two bending parts; and the reinforcing blocks are welded in U-shaped grooves of the two sides through flanges. The structure disclosed by the utility model is suitable for arranging all bent U-shaped cross beams and is also suitable for arranging a mini-type passenger car on a large-plane bend; and under the condition of not changing materials and material thickness of the cross beam, the aim of improving the rigidity and the model state of the cross beam is achieved through reasonably and additionally arranging the reinforcing blocks, so that the effect of improving the whole automobile effect is realized.

Description

A kind of vehicle beam structure
Technical field
The utility model relates to a kind of vehicle beam structure.
Background technology
Crossbeam in the vehicle body is being played the part of the role of bearing vehicle body weight, has installation function concurrently.With crossbeam existing two types on the market is example, and entablatrance welding assembly is that principal section is the rectangular structure of U type before one type, in the main body front sidewall in the middle of form a breach, hood lock reinforcement before the gap portions welding.It has obvious defects, and it only depends on the U-bottom of main body of cross-beam to wear trapezoidal cascaded surface flange and keeps structural strength and the non-deformability of self, and the intensity of self is not in full force and effect.Also have the monomer film that crashproof crossbeam assembly is a flow forming before a kind of automobile in addition, it has paid attention to the maintenance convenience, referring to Fig. 1; Direction shown in the arrow in the drawings, all there is warp architecture in this crossbeam, and 1-1 and 1-2 place; This place intensity a little less than; Be easy to generate and reverse, so it fails to ensure the intensity of self, need the problem paid close attention to so strength problem is still.
Summary of the invention
Not enough to existing design-calculated, the utility model provides a kind of vehicle beam structure, and purpose is to strengthen crossbeam knee rigidity, upper member model frequency before changing, thus satisfy the installation function requirement.
The section of the vehicle beam structure that the utility model proposes is a U-shaped; Also there is trapezoidal bending in the stage casing; Its improvement is: two crooked positions respectively are provided with a boss about the trapezoidal bending of said crossbeam; The shape of said boss is consistent with the shape of corresponding two crooked positions, is welded on through flange in the U-lag on these both sides.
The utility model is on intrinsic basis, and emphasis has been considered the problem of crossbeam self intensity, has increased by two bosses, but does not change the arrangement of original crossbeam, compares with original design, has following advantage:
(1) only changes the arrangement of crossbeam additional strengthening, do not increased the quality burden;
(2) rigidity of crossbeam is highly improved;
(3) largely improve the crossbeam installation function, promoted vehicle performance.
The structure that the utility model relates to is fit to the layout of all crooked U type crossbeams; Also be fit to the layout of microvan at big plain bending; Can not change the crossbeam material and expect under the thick prerequisite; Reach the purpose that improves horizontal type beam rigidity and mode through rational increase boss, thereby reach the effect that promotes vehicle performance.
Description of drawings
Fig. 1 is the structural representation of existing a kind of vehicle beam;
Fig. 2 is the structural representation of the crossbeam of the utility model proposition;
Fig. 3 and Fig. 4 are the structural representation of the boss that increased.
Among the figure: 1 is cross-beam body, and 1-1 and 1-2 are crooked position, and 2 is boss, and 2-1 is the boss body, and 2-2 is the welding flange, and 2-3 is a knock hole, and 2-4 is a lightening hole.
The specific embodiment
The utility model is on the basis of original scheme, and on turn increases a boss respectively.As shown in Figure 2, this boss 2 be arranged in crossbeam trapezoidal bending about two crooked position 1-1 and 1-2, and be positioned at the U-lag of cross-beam body 1.
Referring to Fig. 3 and Fig. 4, the shape of boss 2 is consistent with the shape of corresponding crooked position 1-1 and 1-2, and boss forms the welding assembly through welding flange 2-2 and cross-beam body.Because this crooked position of crossbeam all has bending at fore-and-aft direction and above-below direction; Therefore boss also has the respective curved structure when design; Shown in Figure 3 is the warp architecture of this boss above-below direction; Shown in Figure 4 is the warp architecture of this boss fore-and-aft direction, and these two kinds of warp architectures have well cooperated the structure of cross-beam body, finally forms a kind of later-model vehicle beam structure.Simultaneously, on the boss 2 also reasonable Arrangement lightening hole 2-4, both guaranteed knee intensity, do not increase the tare burden again.Welding process property is also simple.

Claims (2)

1. vehicle beam structure; The section of cross-beam body is a U-shaped; There is trapezoidal bending in the stage casing; It is characterized in that: two crooked positions respectively are provided with a boss about the trapezoidal bending of said crossbeam, and the shape of said boss is consistent with the shape of corresponding two crooked positions, is welded on through flange in the U-lag on these both sides.
2. vehicle beam structure according to claim 1 is characterized in that: be furnished with lightening hole on the said boss.
