Description

A kind of automobile front side member
Technical field
The present invention relates to vehicular spare parts, particularly relate to a kind of automobile front side member.
Background technology
At present, in general body structure, front side member also is the crucial accessory that transmits the absorbing impact impulsive force except as the main load bearing element of auto body.Impulsive force when colliding in order to transmit effectively, the leading portion with front side member connects bumper/spoiler usually, and back segment connects front apron, lets impulsive force disperseed to absorb.Simultaneously, for proof strength, front side member is the enclosed cavity structure mostly, usually enclosed cavity is divided into two parts panel beating (front side member inner panel and front side member outside plate) during production, during assembling with this two parts weld together.But not enough below this structure exists:
1, because the steering box intermediate rod will be dodged in the middle part of general automobile front side member, so the middle part of front side member can be designed a warp architecture usually; And, for minicar, because the spacing of its deflecting bar and front apron is littler, so the bending curvature of its front side member is bigger.And when actual production, this warp architecture causes in the stamped process producing serious wrinkling easily.Therefore, the material of employing is restricted---can't adopt the higher steel plate of intensity under the moulding prerequisite satisfying.Like this, for guaranteeing the intensity of front side member, generally needing increases brace panel, and weight has also increased with regard to corresponding.
2, because multilayer panel beating overlap joint is generally adopted at the warp architecture position of front side member; So the material of this crooked position is thick very thick; For guaranteeing welding quality, often need offer some welding via hole or welding machine grooves at this position, can cause the intensity of this crooked position to reduce like this.
Summary of the invention
The objective of the invention is provides a kind of simple in structure in order to overcome the deficiency of above-mentioned background technology, in light weight and automobile front side member that intensity is high.
In order to realize above purpose, a kind of automobile front side member provided by the invention comprises the front side member body of being with warp architecture, and said front side member body is assembled by two sections at least, and assembly unit face is arranged on the warp architecture position of front side member body.Through the front side member body being designed to the spliced structure of multistage, having solved the problem that the front side member body wrinkles easily in forming process, thereby can adopt intensity higher, the manufacture of materials front side member body that weight is lighter.
In such scheme, said front side member body comprises front side member leading portion, front side member back segment and attaching parts, and the front side member leading portion is connected fixing with the front side member back segment through attaching parts.Certainly, can design more multistage according to actual needs.
In such scheme, the junction of said front side member leading portion and front side member back segment is provided with the front side member diagonal ligament beam that links to each other with the body front wall crossbeam, and this front side member diagonal ligament beam is connected fixing with said front side member body through said attaching parts.Like this, during vehicle collision, front side member diagonal ligament beam can play buffer action with transfer of energy to the bottom skeleton of front shock.
In such scheme, said attaching parts comprises three-way connector and U-shaped connecting panel, and the U-shaped connecting panel is provided with project-welding nut, and said front side member body and front side member diagonal ligament beam are contained between three-way connector and the U-shaped connecting panel through bolt clip respectively.Because can not the welding projection welding nut on the said three-way connector; So in three-way connector, add the U-shaped connecting panel; Welding projection welding nut on the U-shaped connecting panel, like this, said front side member body and front side member diagonal ligament beam just can be contained between three-way connector and the U-shaped connecting panel through bolt clip respectively.
In such scheme, said front side member leading portion is provided with the conquassation muscle, like this, during vehicle collision, can reduce the injury to the occupant through this conquassation muscle distortion energy-absorbing.
In such scheme, have at least one to be the aluminum alloy profiled member in said front side member leading portion, front side member back segment and the front side member diagonal ligament beam, like this, alleviate the weight of this front side member, thereby alleviated the weight of car load.
In such scheme, be provided with reinforced rib in the said front side member back segment, improved the intensity of front side member back segment.
In such scheme, be provided with reinforced rib in the said front side member diagonal ligament beam, improved the intensity of front side member diagonal ligament beam.
In such scheme, said attaching parts is an aluminium alloy casting spare.
In such scheme, be provided with reinforced rib in the said attaching parts, improved the intensity of attaching parts.
One aspect of the present invention through the front side member body being designed to the spliced structure of multistage, having solved the problem that the front side member body wrinkles easily, thereby can adopt intensity higher, the manufacture of materials front side member body that weight is lighter in forming process; On the other hand, add front side member diagonal ligament beam in the junction of said front side member leading portion and front side member back segment, like this, during vehicle collision, front side member diagonal ligament beam can play buffer action with transfer of energy to the bottom skeleton of front shock; On the one hand, add the conquassation muscle again, like this, during vehicle collision, can reduce injury through this conquassation muscle distortion energy-absorbing to the occupant at said front side member leading portion; Another aspect with the said front side member leading portion of aluminum alloy materials moulding, front side member back segment and front side member diagonal ligament beam, has alleviated the weight of this front side member, thereby has alleviated the weight of car load; At last, in front side member back segment, front side member diagonal ligament beam and attaching parts, add reinforced rib respectively, improved the intensity of this front side member.
The present invention and prior art contrast show that fully its preceence is: simple in structure, in light weight, intensity is high, and safety performance is good etc.
