Abstract
The utility model relates to an automobile front longitudinal beam structure. The automobile front longitudinal beam structure comprises a longitudinal beam front section, a longitudinal beam middle section and a longitudinal beam rear section, wherein the thickness from the longitudinal beam rear section and the longitudinal beam front section to the longitudinal beam middle section is gradually thickened, one end of the longitudinal beam middle section is connected with the longitudinal beam front section by welding, and the other end of the longitudinal beam middle section is connected with the longitudinal beam rear section by welding. According to the automobile front longitudinal beam structure disclosed by the utility model, a front longitudinal beam is divided into three sections according to different function requirements and is formed by welding the three parts by respectively adopting different slabs in different materials and thicknesses; on the premise of meeting the automobile body safety, the weight of components is lightened, the number of the components is reduced, and the cost is lowered; and the longitudinal beam front section adopts a thin slab, and thus the collision energy absorption of a whole automobile is facilitated.
Description
Technical field
The utility model relates to auto parts and components, especially a kind of front longitudinal beam structure of automobile.
Background technology
The front side member of auto body has very important effect to bending and the collision safety of car load.The front side member of automobile is being undertaken the effect that absorbs collision energy, resists occupant space distortion, protection occupant.
Front side member of the prior art adopts one-piece construction usually, and it is simple in structure, and is easy to make, but also has following shortcoming:
(1) adopt integral type punch forming structure, because front side member length is longer, and drawing ratio is dark, need to process by larger mould and pressing equipment, and the mould manufacture difficulty is large, and cost is high;
(2) adopt homogenous material to be stamped to form, its intensity is low, and overall performance is poor, is difficult to satisfy front side member and not only absorbs collision energy but also can resist the purpose that occupant space is out of shape.Usually can increase reinforcement at front side member and increase its intensity, but this method not only increases cost, has also increased complete vehicle weight, is unfavorable for the realization of body lightening.
The utility model content
The shortcomings such as the applicant is for processing difficulties in the above-mentioned existing production technology, and intensity is low provide a kind of rational in infrastructure, front longitudinal beam structure of automobile easy to make, thus under the prerequisite that satisfies vehicle body safety, alleviate pts wt, manufacture easyly, reduce cost.
The technical scheme that the utility model adopts is as follows:
A kind of front longitudinal beam structure of automobile, comprise longitudinal beam front section, longeron stage casing and longeron back segment, and the thickness progressive additive from longeron back segment, longitudinal beam front section to the longeron stage casing, one end in described longeron stage casing is by being welded to connect longitudinal beam front section, and the other end in described longeron stage casing and longeron back segment adopt and be welded to connect.
Its further technical scheme is:
It is the high strength cold rolled steel plate of 1.8mm that longitudinal beam front section can adopt thickness;
It is the hot rolled steel plate of 2.3mm that thickness can be adopted in the longeron stage casing;
It is the high strength cold rolled steel plate of 1.4mm that the longeron back segment can adopt thickness.
The beneficial effects of the utility model are as follows:
The utility model is divided into three sections with front side member by different functional requirements, and adopts respectively the sheet material welding of different materials and thickness to form.Under the prerequisite that satisfies vehicle body safety, alleviate pts wt, reduce number of parts and reduce cost.Adopt book sheet material at longitudinal beam front section, be conducive to the collision energy-absorbing of car load.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, front longitudinal beam structure of automobile described in the utility model, comprise longitudinal beam front section 1, longeron stage casing 2 and longeron back segment 3, and the thickness progressive additive from longeron back segment 3, longitudinal beam front section 1 to longeron stage casing 2, one end in longeron stage casing 2 is by being welded to connect longitudinal beam front section 1, and the other end in longeron stage casing 2 and longeron back segment 3 adopt and be welded to connect.
It is the high strength cold rolled steel plate of 1.8mm that longitudinal beam front section 1 can adopt thickness, and model is: B210P1(Q/BQB411).
It is the hot rolled steel plate of 2.3mm that thickness can be adopted in longeron stage casing 2, and model is: SAPH400(Q/BQB310).
It is the high strength cold rolled steel plate of 1.4mm that longeron back segment 3 can adopt thickness, and model is: B210P1(Q/BQB411).
In the Practical manufacturing process, select respectively the material of three kinds of materials as implied above and sheet metal thickness, the mode by laser assembly solder is longitudinal beam front section 1, and 3 three sections of longeron stage casing 2 and longeron back segments are welded into a whole, and then punch forming gets final product, and is easy to make, and cost is low.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
