First transverse slat;
Second transverse slat that is parallel to described first transverse slat;
Riser perpendicular to described first transverse slat and second transverse slat, last horizontal edge is captiveed joint with a horizontal edge of described first transverse slat, following horizontal edge is captiveed joint with a horizontal edge of described second transverse slat, the cross-sectional plane of described riser is set to wavy shaped configuration, described wavy shaped configuration comprises at least two second U-shaped structures, and the opening direction of each second U-shaped structure is opposite with the opening direction of the described first U-shaped structure.
The degree of depth of described each second U-shaped structure is greater than 10 millimeters.
The width of described each second U-shaped structure is greater than 20 millimeters.
Described first U-shaped structure and the described second U-shaped structure are the one roll-forming.
The above-mentioned automobile rear anti-crash beam that the utility model embodiment provides can form by metal sheet being carried out open type roll-in processing and fabricating, and weight is lighter; And required roller set is less, does not need welding in the roll-in process, and manufacture craft is simple, and cost of manufacture is lower; In addition, the automobile that described automobile rear anti-crash beam is installed is when meeting with collision, the part that forms the first U-shaped structure cross-sectional plane on the beam body forms once buffering, the part that forms at least two second U-shaped structure cross-sectional planes on the beam body forms another time buffering, compare with the existing automobile rear anti-crash beam that has the single second U-shaped structure cross-sectional plane or do not have second a U-shaped structure cross-sectional plane, the intensity of above-mentioned automobile rear anti-crash beam is higher, bump the energy of generation after when automobile rear meets with collision, more effectively absorbing, effectively reduce the impact of collision to automobile and occupant, crashworthiness is better, and under the situation of same weight, the crashworthiness of above-mentioned automobile rear anti-crash beam is better than existing automobile rear anti-crash beam.
Description of drawings
Fig. 1 is the schematic perspective view of a kind of automobile rear anti-crash beam among the utility model embodiment;
Fig. 2 is the cross sectional representation of the beam body of automobile rear anti-crash beam among Fig. 1.
The specific embodiment
For technical matters, technical scheme and advantage that the utility model embodiment will be solved is clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, 2, the utility model embodiment provides a kind of automobile rear anti-crash beam, comprising:
Cross-sectional plane is set to the beam body of the first U-shaped structure, comprising:
First transverse slat 1;
Second transverse slat 2 that is parallel to first transverse slat 1;
Riser 3 perpendicular to first transverse slat 1 and second transverse slat 2, last horizontal edge is captiveed joint with a horizontal edge of first transverse slat 1, following horizontal edge is captiveed joint with a horizontal edge of second transverse slat 2, the cross-sectional plane of riser 3 is set to wavy shaped configuration, this wavy shaped configuration comprises at least two second U-shaped structures, and the opening direction of each second U-shaped structure is opposite with the opening direction of the first U-shaped structure.
The method for making of described automobile rear anti-crash beam is:
One metal sheet carried out the open type roll-in, make the metal sheet after the roll-in can mark off above-mentioned first transverse slat part, the second transverse slat partial sum riser part, and cross-sectional plane is the first U-shaped structure that the promptly above-mentioned first U-shaped structure and the second U-shaped structure are the one roll-forming.Above-mentioned metal sheet can adopt ultrahigh-strength steel plates, and its yield strength is greater than 1000MPa.
The method that described automobile rear anti-crash beam is installed on the automobile is: be installed in the automobile rear bumper described automobile rear anti-crash beam or automobile tail, wherein, riser is towards the rear of automobile, makes when automobile meets with collision riser contact-impact thing at first.
