CN2908276Y - Automobile rear floor angle plate - Google Patents

Abstract

The utility model provides an angle-plate structure for the rear plate of the car, which is to arrange a transversal energy-absorbing bar that is longitudinally extended on the existing angle plate of the rear floor, the distance between the energy-absorbing bars is gradually increased. When the rear-collision is happened, the place that is contacted firstly has larger deformation with good energy-absorbing effect; in the whole collision process, the deformation is gradually reduced and the energy absorption is weakened, which not only plays the favorable energy-absorbing effect, but also reduces the damage of the rear floor caused by the collision so as to improve the security of the whole car.

Description

A kind of automobile rear floor gusset

Technical field

The utility model relates to the automotive body structure technology, is specifically related to the rear floor structure of automobile.

Background technology

Back floor on the car mainly is to reduce the destruction that the floor, back is subjected to by back collision longeron is installed in both sides when suffering longitudinal impact at present, i.e. back collision longeron has been born main anti-tampering action, and is therefore higher at the Structural Design Requirement aspect the energy-absorbing to back collision longeron.However, back collision longeron is appointed floor, protection back very effectively, when running into stronger back collision, appoints the havoc that can cause floor, whole back.Usually; the back floor gusset that interconnect function has been arranged between back collision longeron and floor, back; it longitudinally is welded as a whole with back collision longeron; in fact also back collision longeron had booster action; but floor, existing back gusset does not consider to collision energy-absorbing that structurally this is a shortcoming; can't more effectively bring into play its support, floor, protection back to back collision longeron.

Summary of the invention

The purpose of this utility model is to provide a kind of automobile rear floor gusset that improves structure at the problem of prior art existence, designs endergonic structure thereon, back collision longeron is supported floor after the common protection.

Technical solution of the present utility model is on the gusset of floor, existing back the horizontal energy-absorbing muscle of longitudinally arranging to be set, and the distance between the energy-absorbing muscle longitudinally increases progressively step by step.In when collision back, the place of contact distortion earlier is big, and energy-absorbing effect is good, be out of shape to diminish gradually in whole collision process, and energy-absorbing weakens, and has so not only played good energy-absorbing effect, reduced because of collision cause to after the destruction on floor, the safety of raising car load.

Description of drawings

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

Fig. 2 is the section structure scheme drawing after back floor gusset and the welding of back collision collision longeron.

The specific embodiment

Referring to Fig. 1, back floor gusset is a single component, and bending is a L type, and its surface is provided with the horizontal energy-absorbing muscle of longitudinally arranging 1, and the distance between the energy-absorbing muscle longitudinally increases progressively step by step.Back floor gusset 2 directly welds with back collision crossbeam 3, back collision crossbeam is played the support effect, as shown in Figure 2.

Claims (1)

1, a kind of automobile rear floor gusset, it is a single component, and bending is a L type, it is characterized in that, is provided with the horizontal energy-absorbing muscle of longitudinally arranging on the surface of floor, back gusset, and the distance between the energy-absorbing muscle longitudinally increases progressively step by step.
