Abstract
The utility model relates to a rear vehicle floor frame, which comprises a rear cross beam for the rear floor, a strengthening beam for the rear floor and a strengthening beam for the rear cross beam, wherein the end of the rear cross beam for rear floor is welded to the middle part of the strengthening beam for the rear floor, and the strengthening beam for the rear cross beam is welded between the rear cross beam for the rear floor and the strengthening beam for the rear floor, thereby forming a closed triangular rigid structure. Since the rear floor frame of the utility model has a rational and firm triangular rigid structure which is not prone to be destroyed, the vehicle body suffering rear collision has small deformation, therefore reducing the damage caused by collision and guaranteeing the safety in rear collision.
Description
Technical field
The utility model relates to the vehicle body framework construction of automobile.
Background technology
Now general automobile rear floor frame is made up of back floor after cross member and back-floor reinforcement beam; the end of back floor after cross member and the welding of the middle part of back-floor reinforcement beam; be similar to a T word; do not take other strengthening measure; the bulk strength of rear floor frame is not high like this; can not protect vehicle body well when the back collision takes place automobile, it is serious to cause vehicle body to destroy, and has reduced the vehicle body safety.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile rear floor frame at the deficiency of prior art existence, improves the intensity of rear floor frame.
The technical solution of the utility model is as follows:
A kind of automobile rear floor frame, it is made up of floor, back after cross member, back-floor reinforcement beam and after cross member strength beam, the end of back floor after cross member and the welding of the middle part of back-floor reinforcement beam, the after cross member strength beam is welded between back floor after cross member and the back-floor reinforcement beam again, forms the closed triangle rigid construction thus.
When the utility model suffered the back collision at vehicle body, because rear floor frame is the triangle rigid construction, structure was comparatively reasonable, firm, be not easy destroyed, so deflection is little when the collision of back, has reduced the destruction of causing because of collision, has guaranteed the safety of back collision.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, this rear floor frame is made up of three parts, be respectively floor, back after cross member 1, back-floor reinforcement beam 2 and after cross member strength beam 3, the end of back floor after cross member 1 and the welding of the middle part of back-floor reinforcement beam 2, after cross member strength beam 3 is welded between back floor after cross member 1 and the back-floor reinforcement beam 2 again, forms closed triangle.
Claims (1)
1, a kind of automobile rear floor frame, it includes back floor after cross member and back-floor reinforcement beam, the end of back floor after cross member and the welding of the middle part of back-floor reinforcement beam; It is characterized in that: also be provided with the after cross member strength beam, the after cross member strength beam is welded between back floor after cross member and the back-floor reinforcement beam, and the three forms the closed triangle rigid construction jointly.
