Abstract
The invention provides a lapping system for an automobile body side wall and a top cover front beam, which comprises an A post reinforcing plate, an A post upper inner plate and a top cover reinforcing beam, wherein the A post reinforcing plate is provided with a lapping joint which is a concave platform; and the A post upper inner plate and the top cover front beam are both lapped with the A post reinforcing plate at the lapping joint. The lapping system has the advantages that the lapping joint of the A post reinforcing plate is the concave platform, the three layers of plates of the A post reinforcing plate, the A post upper inner plate and the top cover front beam are welded at the lapping joint, and the lapping cross section of the top cover front beam is of a ladder shape, thereby improving the lapping strength and rigidity, and preventing cracks caused by stress concentration. The lapping system has simple molding process, and saves materials of the A post upper inner plate.
Description
[technical field]
The present invention relates to the earth system of a kind of body side wall and top cover front cross rail, be specifically related to technological improvement the earth system of body side wall and top cover front cross rail.
[background technology]
The body side wall of existing vehicle and the earth system of top cover front cross rail comprise inner panel on the A post in the market, A-pillar reinforcement plate and top cover front cross rail, as shown in Figure 1: A-pillar reinforcement plate 2, top cover front cross rail 3 are distinguished separately and inner panel 1 welding on the A post, this kind structure causes front windshield upper corner stress concentration, even causes cracking.Some vehicle is for preventing cracking, often the inner panel on the A post 1 and the lap joint of top cover front cross rail 3 stretch very long, make the forming process difficulty so again, and cause waste of material.
[summary of the invention]
In order to solve the earth system stress concentration of existing body side wall and top cover front cross rail, and the technical matters of forming process difficulty and waste material, the invention provides a kind of earth system of body side wall and top cover front cross rail of new construction.
The present invention solves the technical scheme that existing technical matters adopts: the earth system that a kind of body side wall and top cover front cross rail are provided, comprise the A-pillar reinforcement plate, inner panel and top cover front cross rail on the A post, it is a concave station that the A-pillar reinforcement plate has a lap joint, described lap joint, and inner panel and top cover front cross rail are all at described lap joint place and A-pillar reinforcement plate overlap joint on the A post.
The present invention further improves, and the A-pillar reinforcement plate maintains static, and inner panel direction outside vehicle body moves a distance L on the A post, and L is 20-35mm, makes that inner panel is at described lap joint place and A-pillar reinforcement plate overlap joint on the A post.
The present invention further improves, and the inner panel distance L that direction moves outside vehicle body is 20mm on the A post.
The present invention further improves, and the A-pillar reinforcement plate maintains static, and top cover front cross rail direction outside vehicle body moves a distance L, and L is 20-35mm, makes the top cover front cross rail at described lap joint place and A-pillar reinforcement plate overlap joint.
The present invention further improves, and the top cover front cross rail distance L that direction moves outside vehicle body is 20mm.
The present invention further improves, and described top cover front cross rail has an overlap joint cross section, and described overlap joint cross section is stepped.
Compared to prior art, the invention has the beneficial effects as follows: the described lap joint that makes the A-pillar reinforcement plate is a concave station, inner panel, top cover front cross rail and A-pillar reinforcement plate three ply board weld in described lap joint place on the A post, and top cover front cross rail overlap joint cross section is stepped, this has improved bond strength, rigidity, prevent the cracking that stress concentration causes, forming process is simple and saved the materials of inner panel on the A post.
[description of drawings]
Fig. 1 is the structural representation of the earth system of the body side wall of prior art and top cover front cross rail;
Fig. 2 is the structural representation of the earth system of body side wall of the present invention and top cover front cross rail.
[specific embodiment]
Below in conjunction with the description of drawings and the specific embodiment the present invention one is gone on foot explanation.
With reference to Fig. 2, the earth system of a kind of body side wall and top cover front cross rail comprises A-pillar reinforcement plate 10, inner panel 20 and top cover front cross rail 30 on the A post.Inner panel is the name of automobile manufacture industry to particular component on A-pillar reinforcement plate and the A post, and the structure of inner panel is complicated on A-pillar reinforcement plate and the A post.
It is a concave station that A-pillar reinforcement plate 10 has a lap joint 11, described lap joint 11, inner panel 20 and top cover front cross rail 30 are all at described lap joint 11 places and A-pillar reinforcement plate 10 overlap joints on the A post, this three ply board has disperseed stress in the system of described lap joint place welding, and bond strength has also improved.Top cover front cross rail 30 has an overlap joint cross section 31, and described overlap joint cross section 31 is stepped, is convenient to the overlap joint of described overlap joint cross section 31 and described lap joint 11.
A-pillar reinforcement plate 10 maintains static, inner panel 20 direction outside vehicle body moves a distance L on the A post, and L is 20-35mm, and L is preferably 20mm, make that inner panel 20 moves the materials that a distance L has also been saved inner panel 20 on the baroque A post at described lap joint 11 places and A-pillar reinforcement plate 10 overlap joints on the A post.
A-pillar reinforcement plate 10 maintains static, and top cover front cross rail 30 direction outside vehicle body moves a distance L, and L is 20-35mm, and L is preferably 20mm, makes top cover front cross rail 30 at described lap joint 11 places and A-pillar reinforcement plate 10 overlap joints.
The lap joint 11 of A-pillar reinforcement plate 10 of the present invention changes, be a concave station, inner panel 20, top cover front cross rail 30 and A-pillar reinforcement plate 10 three ply boards weld at described lap joint 11 places on the A post, and the overlap joint cross section 31 of top cover front cross rail 30 is stepped, this has improved bond strength, rigidity, prevent the cracking that stress concentration causes, forming process is simple and saved the materials of inner panel 20 on the A post.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
