Abstract
The utility model provides an integrated floor beam. According to the integrated structure of the integrated floor beam, the cross section is of a U shape and the structure is formed by bar-type boards in a stamping mode. A section of arched beam is arranged on the integrated floor beam. The integrated floor beam is high in material use ratio, small in number of parts and molds, good in uniformity of products and capable of eliminating external welding lines and welding overlap edges, improving the corrosion resistance and the light weight level and improving the transverse strength and the side impact safety of a vehicle.
Description
Technical field
The utility model relates to a kind of auto parts and components, is specifically related to a kind of integral type floor crossbeam.
Background technology
Auto body is the basis of the various aspects of performance such as vehicle security, traveling comfort, reliability.Wherein, front floor crossmember is car load collision safety, torsional stiffness, chair mounted provide significant contribution.
In prior art, floor crossmember comprises floor front cross rail and floor after cross member, both are three stage structure, as shown in Figure 1 and Figure 2, comprise the left crossbeam 101 in floor, the right crossbeam 103 of floor middle 102 and floor, the right crossbeam of the left crossbeam in floor and floor welds by solder joint 104 and floor middle respectively.The floor crossmember that Figure 2 shows that prior art is arranged on the structural representation on vehicle body, wherein, the right crossbeam 103 of the left crossbeam 101 in floor and floor is welded in the top on floor, floor middle 102 is welded in the below on floor, and the two ends, left and right of floor crossmember overlap with the right, Liang Heqian floor, the left side, front floor beam respectively.This structure has following shortcoming: (1) stock utilization is low, and number of molds is many, and punching press, welding cost are high; (2) weld undercapacity, stress is concentrated, and easy crumple during side impact jeopardizes driver and crew's living space; (3) amount of parts is many, and homogeneity of product is poor; (4) floor middle is below floor, and the weld seam between floor is exposed to below, floor, and rotproofness is poor; (5) in floor crossmember, lap plate is more, and lightweight level is low.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of integral type floor crossbeam, by the improvement of structure, stock utilization is high, amount of parts is few, number of molds is few, good product consistency, cancel outside weld seam and welded lap limit, improve corrosion stability and lightweight level, improve lateral direction of car intensity and side impact safety.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of integral type floor crossbeam, be welded in the top of body platform, described floor crossmember is that cross-sectional plane is the one-piece construction of U-shaped, this integral type floor crossbeam is provided with one section of arched beam, guarantees the arrangement space of freeing pipe or transmission shaft.
Further, described arched beam is located at the middle part of described integral type floor crossbeam.
Wherein, on described body platform, the position corresponding with described arched beam is provided with channel groove in floor.
Preferably, this integral type floor crossbeam is by the punch forming of bar shaped sheet material.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, floor crossmember is stamping forming one-piece construction, stock utilization is high, amount of parts is few, number of molds is few, good product consistency, cancels outside weld seam and welded lap limit, improves corrosion stability and lightweight level, improves lateral direction of car intensity and side impact safety.

The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The stock utilization that the utility model exists for existing floor crossmember is low, and number of molds is many, and punching press, welding cost are high, weld undercapacity, stress is concentrated, easy crumple during side impact, the living space that jeopardizes driver and crew, amount of parts is many, and homogeneity of product is poor, weld seam is exposed to below, floor, and rotproofness is poor, and in floor crossmember, lap plate is more, the problems such as lightweight level is low, provide a kind of integral type floor crossbeam.
As shown in Figure 3, Figure 4, embodiment of the present utility model provides a kind of integral type floor crossbeam, for cross-sectional plane be U-shaped, by the stamping forming one-piece construction of bar shaped sheet material, the middle part of this integral type floor crossbeam 301 is provided with one section of arched beam 302, the below radian of this arched beam 302 is consistent with the below radian of floor middle in prior art, guarantees the arrangement space of freeing pipe or transmission shaft.
This integral type floor crossbeam 301 is welded in the top of body platform 201, and its two ends, left and right overlap with the left side, front floor beam 202 and the right, front floor beam 203 respectively.
Position corresponding with described arched beam 302 on described body platform 201 is provided with channel groove 401 in floor, for holding described arched beam 302.
The floor crossmember that the utility model embodiment mono-provides is stamping forming one-piece construction, stock utilization is high, amount of parts is few, number of molds is few, good product consistency, cancel outside weld seam and welded lap limit, improve corrosion stability and lightweight level, improve lateral direction of car intensity and side impact safety.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvement or replacement, these improvement or replacement also should be considered as protection domain of the present utility model.
