Abstract

The utility model discloses a rear bumper component assembly of a saloon car. The rear bumper component assembly comprises a rear bumper component (1). Damping parts (2) are arranged at the left end and the right end of the rear bumper component (1), the rear ends of the damping parts (2) and the rear bumper component (1) are welded, the front ends of the damping parts (2) and a component plate (3) are welded, and the damping parts (2) are of a hollow column structure. The circumferential surface of each damping part (2) is formed by four planes and four V-shaped surfaces, and the planes and the V-shaped surfaces are distributed at intervals. A reinforcing rib protruding forwards is additionally arranged, so the springback of the rear bumper component of the saloon car in the arc direction can be avoided effectively, accuracy of the rear bumper component is improved, and the requirements for assembly in the later stage can be well met. In addition, the shapes of the damping parts are changed, the structural strength of the rear bumper component assembly of the saloon car can be reliable, the rear bumper component assembly is not prone to deformation or damage, and therefore the rear bumper component assembly of the saloon car has the advantages of being novel in conception, reasonable in design, simple in structure, easy to reform, low in reforming cost and the like.

Description

Car rear bumper structural member assembly

Technical field

The utility model belongs to car technical field, particularly the rear bumper structural member assembly on car.

Background technology

Car rear bumper structural member assembly is the vitals on car, plays a part crashproof.Existing car rear bumper structural member assembly generally consists of rear bumper member, damping and panels, because rear bumper member easily produces resilience in its radian direction, can affect like this precision of car rear bumper, is difficult to meet the matching requirements in later stage; In addition, damping is generally square, causes its structural strength poor, is easier to deform or damage.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of can effectively prevent damping distortion or the car rear bumper structural member assembly damaging.

The technical solution of the utility model is as follows: a kind of car rear bumper structural member assembly, comprise rear bumper member (1), at the two ends, left and right of rear bumper member (1), be provided with damping (2), the rear end of this damping (2) and rear bumper member (1) welding, the front end of damping (2) and panels (3) welding, its key is: described damping (2) is hollow pillar structure, all sides of damping (2) are comprised of four planes and four V-arrangement faces, and described plane and V-arrangement face are spaced apart.

The utility model changes damping into all side and is comprised of four planes and four V-arrangement faces, and four planes and four V-arrangement faces spaced apart, can effectively promote like this structural strength of damping, make it be not easy to deform or damage.

In order to ensure intensity, also reduce costs as far as possible, described damping (2) is made by the high-strength plate of thick 1.2mm.

As preferably, the V-arrangement distributing on all sides of described damping (2) is 8mm towards the interior recessed degree of depth.

On described rear bumper member (1), be provided with the reinforced rib (4) of a lordosis, this reinforced rib (4) extends to right-hand member from the left end of rear bumper member (1), and this reinforced rib (4) equates with the distance to rear bumper member (1) base to the distance of rear bumper member (1) top margin.

The utility model arranges the reinforced rib of a lordosis on rear bumper member, this reinforced rib can increase the structural strength of rear bumper member bodies, play the effect of shaping, thereby effectively prevented that rear bumper member bodies is in its radian direction generation resilience, improve the precision of product, can meet better the requirement of later stage assembling.

In order to facilitate selection, guarantee structural strength, described rear bumper member (1) is that the high-strength plate that 1.2mm, yield strength are 780MPa is made by thickness.

As preferably, the width of described reinforced rib (4) is 60mm.

As preferably, the height that described reinforced rib (4) protrudes is 12mm.

Beneficial effect: the utility model by setting up the reinforced rib of a lordosis on car rear bumper member, can effectively prevent that car rear bumper member is in its radian direction generation resilience, thereby improved the precision of product, can meet better the requirement of later stage assembling; In addition, the utility model, by changing the moulding of damping, makes its structural strength reliable, is not easy to deform or damage.The utlity model has the features such as novel, reasonable in design, simple in structure, transformation is easy, improvement cost is low.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the birds-eye view of Fig. 1.

Fig. 3 is the structural representation of damping.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

As shown in Figure 1 and Figure 2, the utlity model has rear bumper member 1, the strip shape cambered plate structure that this rear bumper member 1 is lateral arrangement.Described rear bumper member 1 is that the high-strength plate that 1.2mm, yield strength are 780MPa is made by thickness, on described rear bumper member 1, be provided with the reinforced rib 4 of a lordosis, this reinforced rib 4 extends to right-hand member from the left end of rear bumper member 1, and this reinforced rib 4 equates with the distance to rear bumper member 1 base to the distance of rear bumper member 1 top margin, the width of described reinforced rib 4 is 60mm, the height that described reinforced rib 4 protrudes is 12mm, the moulding of described rear bumper member 1 is same as the prior art, at this, does not repeat.

As shown in Figure 1, Figure 2, Figure 3 shows, at the two ends, left and right of rear bumper member 1, be provided with damping 2, the rear end of this damping 2 and 1 welding of rear bumper member, the front end of damping 2 and panels 3 welding.Described damping 2 is hollow pillar structure, by the high-strength plate of thick 1.2mm, is made, and all sides of damping 2 are comprised of four planes and four V-arrangement faces, described plane and V-arrangement face are spaced apart, plane is relative between two, and V-arrangement face is also relative between two, and V-arrangement is 8mm towards the interior recessed degree of depth.
