Detailed description of the invention
For making object of the present invention, technical scheme and advantage clearly understand, to develop simultaneously embodiment referring to accompanying drawing, the present invention is described in more detail.
Refer to Fig. 1 to Fig. 4, the vehicle door anti-collision mechanism 10 in the present embodiment is installed in the driver door 20 of automobile, and this driver door 20 is installed between the A post 30a of automobile and B post 30b, and this vehicle door anti-collision mechanism 10 comprises:
Front mounting plate 11, it is installed in the front bezel 21 of driver door 20 near A post 30a;
Rear adapter plate 12, it is installed in the rear frame 22 of driver door 20 near B post 30b;
Anti-collision pipe 13, its leading portion 131 is fixed on front mounting plate 11, back segment 132 is fixed on rear adapter plate 12, stage casing 130 between leading portion 131 and back segment 132 extends between front mounting plate 11 and rear adapter plate 12;
Brace panel 14, its installing (can pass through welding manner) is in the stage casing 130 of anti-collision pipe 13.
As above visible, vehicle door anti-collision mechanism 10 in the present embodiment has set up brace panel 14 in the stage casing 130 of anti-collision pipe 13, therefore, anti-collision pipe 13 and brace panel 14 just can be utilized when colliding jointly to realize making contact and produce the energy absorbing efficiency proportional with making contact area.Further, the making contact area formed when clashing into due to anti-collision pipe 13 and brace panel 14 is greater than the contacts contact face that anti-collision pipe 13 forms separately and amasss, and thus the present embodiment can improve the energy absorbing efficiency of vehicle door anti-collision mechanism 10.
Record through experiment, when the making contact area length in the direction from front to rear of a vehicle body that brace panel 14 and anti-collision pipe 13 are formed be greater than 200mm, height on bodywork height direction be greater than 80mm time, energy absorbing efficiency is better.
And, record through experiment, in order to make vehicle door anti-collision mechanism 10, there is enough energy-absorbing intensity, the tensile strength of anti-collision pipe 13 can be set to the value being more than or equal to 1500MPa, and the tensile strength of front mounting plate 11, rear adapter plate 12 and brace panel 14 can be set to the value being more than or equal to 400MPa.Correspondingly, in order to reach above-mentioned tensile strength, the thickness of pipe of anti-collision pipe 13 can be set to 2 ~ 3mm, and the thickness of front mounting plate 11, rear adapter plate 12 and brace panel 14 can be set to the value being more than or equal to 1mm.
In addition, consider that the position of collision of actual generation is usually closer to the B post 30b of automobile, therefore, in the present embodiment, compared to the connection mode of anti-collision pipe 13 near leading portion 131 frame 21 place before driver door 20 of A post 30, anti-collision pipe 13 adopts more firm being fixedly connected with near the back segment 132 of B post at after-frame 22 place of driver door 20.
Please see composition graphs 5 again while Fig. 1 to Fig. 4, the anterior 11a of front mounting plate 11 in the direction from front to rear of a vehicle body rear portion 11b that is overlapping with A post 30a location, front mounting plate 11 is positioned at the rear side of A post 30a in the direction from front to rear of a vehicle body, further, the anterior 11a of front mounting plate 11 is fixed on the front bezel 21 of driver door 20, the rear portion 11b of front mounting plate 11 suspends;
Correspondingly, the leading portion 131 of anti-collision pipe 13 is positioned at the scope of the rear portion 11b of front mounting plate 11 and is fixedly connected with the rear portion 11b of front mounting plate 11.
Please see composition graphs 6 again while Fig. 1 to Fig. 4, the anterior 12a of rear adapter plate 12 is positioned at the front side of B post 30b and overlapping with B post 30b location in the direction from front to rear of a vehicle body with the rear portion 12b of overlapping, the rear adapter plate 12 in door inner panel location of driver door 20 in the direction from front to rear of a vehicle body, further, the anterior 12a of rear adapter plate 12 and rear portion 12b is all fixed on the rear frame 22 of driver door 20;
Correspondingly, the anterior 12a that the back segment 13 of anti-collision pipe 13 runs through rear adapter plate 12 is with rear portion 12b and be all fixedly connected with rear portion 12 with the anterior 12a of rear adapter plate 12, to guarantee that the back segment 13 of anti-collision pipe 13 exists a part of location overlap with B post 30b in the direction from front to rear of a vehicle body.
As above visible, in the position near A post 30a, front mounting plate 11 is fixedly connected with the front bezel 21 of driver door 20 by means of only its anterior 11a, and the rear portion 11b that the leading portion 131 of anti-collision pipe 13 only suspends with front mounting plate 11 is fixedly connected with, and by contrast, in the position near B post 30, the anterior 12a of rear adapter plate 12 is fixedly connected with the rear frame 22 of the equal driver door of rear portion 12b 20, and the back segment 132 of anti-collision pipe 13 is fixedly connected with rear portion 12 with the anterior 12a of rear adapter plate 12 simultaneously, obviously, anti-collision pipe 13 is more stable near being fixedly connected with of adopting at after-frame 22 place of driver door 20 of the back segment 132 of B post.
Thus, when colliding in the position near B post 30b, anti-collision pipe 13 will be subject to the stop of B post 30b near the back segment 132 of B post and the part of B post 30b location overlap, and then the back segment 132 of anti-collision pipe 13 just can be avoided as much as possible to bend to automotive interior with front mounting plate 11 for fulcrum and depart from the after-frame 22 of driver door 20, correspondingly, the back segment 132 due to anti-collision pipe 13 just can be avoided as far as possible to bend to automotive interior and clash into the personnel taken in automobile.
Record through experiment, when a part (i.e. the back segment 132 of anti-collision pipe 13 and the part of the B post 30b location overlap) development length (as the X0 that Fig. 6 marks) in the direction from front to rear of a vehicle body that the back segment 132 of anti-collision pipe 13 is arranged in the rear portion 12b scope of rear adapter plate 12 is more than or equal to 25mm, back segment 132 blocking effect of the anti-collision pipe 13 that B post 30b is right is better.
