Technical field
The present invention is about a kind of body structure, particularly part body structure in a kind of machinery space integral type.
Background technology
Driving engine is the parts that automobile is important and accurate.For guaranteeing its normal installation and operation, conventionally need multiple associated components provide safeguard and assist for it.Machinery space assembly is the vitals wherein providing safeguard for driving engine.
Machinery space assembly is the pith of machinery space assembly automotive body welding assembly, is generally placed on part welding on welding main line, and the machinery space assembly integral Z-direction upper part that moves vertically downward finally welds with frame assembly overlap joint.
On at present common machinery space assembly integral, part structure is for once turnup structure of front-wheel bound edge edge, with the welding of chassis side rail flange Y-direction overlap joint.Therefore, cause accuracy error to cause in a process interfering or fit badly, and a turnup structure intensity is not high.In addition, on machinery space assembly integral during part, be difficult to guarantee upper do not interfere or welded lap laminating good.
For solve accuracy error in structure cause interfering in upper process or fit bad, be difficult to guarantee upper do not interfere or the technical matters such as welded lap laminating is good, a kind of new structure need to be provided.
Summary of the invention
For solving the problems of the technologies described above, the invention provides part body structure in a kind of machinery space integral type, it comprises: machinery space assembly parts, and described machinery space assembly parts comprise: front-wheel bag and A-pillar; With frame assembly parts, and described frame assembly parts comprise: front connecting panel, rear connecting panel and column lower connecting plate, wherein: described front-wheel bag and described front connecting panel have overlap and in a longitudinal direction by being welded and fixed, described front-wheel bag and described rear connecting panel have overlap and by being welded and fixed, and described A-pillar and described column lower connecting plate has overlap and by being welded and fixed.
Alternatively, in the clinch office of described front-wheel bag and described rear connecting panel, the edge of described front-wheel bag has the front-wheel bag turnup structure of outside secondary.
Alternatively, described quadric flanging structure is Z-shaped.
Alternatively, the lower end of described A-pillar has A-pillar turnup structure.
Alternatively, described A-pillar turnup structure is 30～60 °.
Alternatively, the relatively described A-pillar of described column lower connecting plate has concave inward structure.
Alternatively, described concave inward structure is positioned at the end of described column lower connecting plate.
Alternatively, the distance of the relatively described A-pillar of described concave inward structure is 2～5 millimeters.
The overlap joint of upper body structure of the present invention by each parts is also welded and fixed, make it become integrated support structure, in installation, location and the course of processing, precision is improved, meanwhile, its structure can guarantee that in part process, welding laminating well, does not produce part structure on interference, intensity failure-free.

The specific embodiment
As shown in Figures 1 to 6, the invention provides part body structure in a kind of machinery space integral type, it comprises: machinery space assembly parts, and described machinery space assembly parts comprise: front-wheel bag 1 and A-pillar 2; With frame assembly parts, and described frame assembly parts comprise: front connecting panel 4, rear connecting panel 5 and column lower connecting plate 3, wherein: described front-wheel bag 1 has overlap with described front connecting panel 4 and in a longitudinal direction by being welded and fixed, described front-wheel bag 1 has overlap with described rear connecting panel 5 and by being welded and fixed, with described A-pillar 2 with under described column, be connected that 3 plates have overlap and by being welded and fixed.
In an embodiment of the present invention, longitudinally represent Z-direction, laterally represent Y direction, vehicle body fore-and-aft direction is X-axis.When mounted, in the present invention, part body structure is installed along the direction of Z axis, and top-down is installed along the negative sense of Z axis.
Adopt after technique scheme, while having realized in machinery space assembly integral formula part, machinery space associated components and vehicle frame associated components are not interfered in upper process, and welding laminating well.
The overlap joint of upper body structure of the present invention by each parts is also welded and fixed, make it become integrated support structure, in installation, location and the course of processing, precision is improved, meanwhile, its structure can guarantee that in part process, welding laminating well, does not produce part structure on interference, intensity failure-free.
As the preferred embodiments of the present invention, as shown in Figure 3, the clinch office at described front-wheel bag 1 with described rear connecting panel 5, the edge of described front-wheel bag 1 has the front-wheel bag turnup structure 11 of outside secondary.Preferably, described quadric flanging structure 11 is Z-shaped.Front-wheel bag edge designs quadric flanging structure, can improve self intensity of this part greatly, is also conducive to carrying out and the welding of mounting process simultaneously.
As preferred version of the present invention, as shown in Figure 5, the lower end of described A-pillar 2 has A-pillar turnup structure 21.Preferably, described A-pillar turnup structure is 30～60 °, and for example optimal design is 45 °.Problems such as interfering when this structure can effectively solve in the machinery space assembly integral formula in actual production part, fit and be bad has guaranteed ovelapping spot weld quality simultaneously, has improved and has been welded to connect intensity.
As present invention further optimization scheme, the relatively described A-pillar 2 of described column lower connecting plate 3 has concave inward structure 31.Preferably, described concave inward structure 31 is positioned at the end of described column lower connecting plate 3.As further improving, the distance of the relatively described A-pillar 2 of described concave inward structure 31 is 2～5 millimeters, for example preferred 3 millimeters.
Machinery space body structure of the present invention is simple, can effectively solve in actual production machinery space assembly integral formula on the problem such as bad of interfering during part, fit, guaranteed ovelapping spot weld quality simultaneously, improved and be welded to connect intensity.Adopt after technique scheme, while having realized in machinery space assembly integral formula part, machinery space associated components and vehicle frame associated components are not interfered in upper process, and welding laminating well; Secondly, can greatly improve self intensity of structure; Again, can well improve welding process.
Should be appreciated that invention which is intended to be protected is not limited to non-limiting embodiments, should be appreciated that non-limiting embodiments describes as just example.The protection domain of the essence that the application will require is more embodied in the scope that independent claims provide, with and dependent claims.
