Abstract
The utility model provides a segmented butt-welding type automobile front longitudinal beam which comprises a longitudinal beam front segment, a longitudinal beam middle segment and a longitudinal beam rear segment which are respectively shaped by punching, wherein the longitudinal beam front segment, the longitudinal beam middle segment and the longitudinal beam rear segment are connected into a whole through butt-welding form, and the thicknesses of materials of the longitudinal beam front segment, the longitudinal beam middle segment and the longitudinal beam rear segment gradually increase. The front longitudinal beam is divided into three segments according to different functional requirements, which can be respectively butt-welded by adopting sheet materials with different materials and thicknesses. Under the premise of guaranteeing the safety of an automobile body, the utility model can realize using a small die for processing accessories, reduces manufacture difficulty, and saves cost. Thinner sheet materials are applied in part of an energy-absorbing area, which is beneficial for reducing the weight of the automobile body, and providing more economical products.
Description
Technical field
The utility model relates to the automotive body structure field, relates in particular to a kind of structure of automobile front side member.
Background technology
The front side member of auto body has very important effect to the bending and the collision safety of car load.The front side member of automobile is being undertaken, and absorbs collision energy, resists the effect that occupant space is out of shape, protects the occupant.The integral type punching structure is generally all adopted in traditional front side member 11 (as shown in Figure 1) design, and its major defect is: longeron length is longer, and drawing ratio is dark, needs bigger mould and pressing equipment to process, and the mould-manufacturing difficulty is big, the cost height.And the longeron intensity that homogenous material is stamped to form is difficult to satisfy longeron and not only absorbs collision energy but also can resist the purpose that occupant space is out of shape preferably; usually can in longeron, solve this problem by newly-increased inner reinforcement 12; increase complete vehicle weight when increasing cost, be unfavorable for the realization of body lightening.
Summary of the invention
The utility model proposes a kind of segmentation welding formula automobile front side member at the prior art deficiency, and this automobile front side member is under the prerequisite that satisfies vehicle body safety, and good manufacturability reduces manufacture difficulty, saves cost.
The technical solution of the utility model is as follows:
A kind of segmentation welding formula automobile front side member, comprise stamping forming longitudinal beam front section, longeron stage casing, longeron back segment respectively, described longitudinal beam front section, longeron stage casing, longeron back segment are linked to be an integral body by the form of welding, and the material thickness progressive additive from longitudinal beam front section, longeron stage casing to the longeron back segment.
Front side member is divided into three sections by different functional requirements, can adopts the sheet material welding of different materials and thickness to form respectively.Under the prerequisite that satisfies vehicle body safety, can realize utilizing little Mould Machining part, reduce manufacture difficulty, save cost.At the sheet material of part employing in energy-absorbing district than book, help the lightweight of vehicle body, more economic product is provided.
Description of drawings
Fig. 1 is a prior art front rail structure scheme drawing;
Fig. 2 is the utility model structural representation;
Wherein, 11-longeron, the inner reinforcement of 12-, 21-longitudinal beam front section, 22-longeron stage casing, 23-longeron back segment, 24-weld seam
The specific embodiment
Referring to Fig. 2, the front side member of vehicle right and left is divided into 23 3 sections of longitudinal beam front sections 21, longeron stage casing 22, longeron back segment by different function zonings, select different materials and sheet metal thickness respectively for use, utilize little die stamping moulding, adopt the form of laser assembly solder to be linked to be an integral body.
It is the sheet material of 1.8mm that longitudinal beam front section 21 is selected thickness for use, and it is the sheet material of 2.0mm that thickness is selected in longeron stage casing 22 for use, and it is the sheet material of 2.6mm that longeron back segment 23 is selected thickness for use.Longeron material selection B 340/590 DP (Q/BQB 418 2003).
Claims (2)
1, a kind of segmentation welding formula automobile front side member is characterized in that: before, during and after described longeron is divided into three sections, and adopt the welding form to connect into an integral body, and the material thickness progressive additive from longitudinal beam front section, longeron stage casing to the longeron back segment.
2, segmentation welding formula automobile front side member according to claim 1, it is characterized in that: it is the sheet material of 1.8mm that described longitudinal beam front section is selected thickness for use, and it is the sheet material of 2.0mm that thickness is selected in the longeron stage casing for use, and it is the sheet material of 2.6mm that longeron back segment (23) is selected thickness for use.
