Description
Technical field
The invention belongs to automobile technical field, be specifically related to a kind of Single-board structural internal truss car body.
Background technology
Mostly existing single-skin panel construction car car body is that first making vehicle body supports/strengthen truss structure, then on this truss structure, lay external mono-layers plate covering.In this body construction, the truss structure of vehicle body assume responsibility for most loads, and external mono-layers plate covering only forms car body outer covering piece, and the load born is very little, and part is more, and manufacturing process is more loaded down with trivial details.
Summary of the invention
Object of the present invention is exactly the defect for prior art, provides a kind of Single-board structural internal truss car body.
The technical solution used in the present invention is: a kind of Single-board structural internal truss car body, comprise multiple inner support beam, described inner support beam is connected with sidepiece single-skin panel covering, top monolayer plate covering and rear portion single-skin panel covering, base plate is provided with bottom described inner support beam, described sidepiece single-skin panel covering, top monolayer plate covering, between rear portion single-skin panel covering and base plate, welding is formed into vehicle body frame structure, the weld of described sidepiece single-skin panel covering and top monolayer plate covering forms the first cavity, the second cavity is formed between described sidepiece single-skin panel covering and base plate.
Further, convex edge is formed to horizontal direction turnover again downwards after described top monolayer plate covering left and right edges at two ends turns down, described sidepiece single-skin panel covering upper end end is provided with the first round edge of horizontal-extending in car body, and described convex edge and the first round edge enclose the first cavity.
Further, the base of the described convex edge for enclosing the first cavity and the support and connection of inner support beam.
Further, two ends, described base plate left and right end is provided with the inclined side upwards extended, and described sidepiece single-skin panel covering lower end end is provided with the second round edge of horizontal-extending in car body, and described inclined side and the second round edge enclose the second cavity.
Further, described inclined side for enclosing the second cavity and the support and connection of inner support beam.
The present invention be by between single-skin panel covering form formed covering carrying cavity and vehicle body support beam jointly form a kind of Nei Shengshi truss, realize single-skin panel construction car car body peripheral covering and the inner support beam shared capacity of body.
The present invention can realize single-skin panel construction car car body peripheral covering and the inner support beam shared capacity of body, reduces making vehicle body separately and supports/strengthen truss structure, reduce part, and then reach the object alleviating car body weight.
Accompanying drawing explanation
Fig. 1 is body construction schematic diagram of the present invention;
Fig. 2 is the structural representation that vehicle body support beam of the present invention and side body single-skin panel covering, car body top single-skin panel covering form the first cavity;
Fig. 3 is the structural representation that vehicle body support beam of the present invention and hull bottom plate, side body single-skin panel covering form the second cavity.
In figure: 1-inner support beam, 2-base plate (2.1-inclined side), 3-sidepiece single-skin panel covering (3.1-first round edge, 3.2-second round edge), 4-top monolayer plate covering (4.1-convex edge), 5-rear portion single-skin panel covering, 6-first cavity, 7-second cavity.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, is convenient to be well understood to the present invention, but they do not form restriction to the present invention.
As shown in Fig. 1-Fig. 3, the present invention includes multiple inner support beam 1, described inner support beam 1 is connected with sidepiece single-skin panel covering 3, top monolayer plate covering 4 and rear portion single-skin panel covering 5, base plate 2 is provided with bottom described inner support beam 1, described sidepiece single-skin panel covering 3, top monolayer plate covering 4, between rear portion single-skin panel covering 5 and base plate 2 welding be formed into vehicle body frame structure, described sidepiece single-skin panel covering 3 forms the first cavity 6 with the weld of top monolayer plate covering 4, forms the second cavity 7 between described sidepiece single-skin panel covering 3 and base plate 2.
As shown in Figure 2, convex edge 4.1 is formed to horizontal direction turnover again downwards after described top monolayer plate covering about 4 edges at two ends turns down, described sidepiece single-skin panel covering 3 upper end end is provided with the first round edge 3.1 of horizontal-extending in car body, and described convex edge 4.1 and the first round edge 3.1 enclose the first cavity 6.The base of the described convex edge 4.1 for enclosing the first cavity 6 and inner support beam 1 support and connection.
As shown in Figure 3, described base plate about 2 two ends end is provided with the inclined side 2.1 upwards extended, described sidepiece single-skin panel covering 3 lower end end is provided with the second round edge 3.2 of horizontal-extending in car body, and described inclined side 2.1 and the second round edge 3.2 enclose the second cavity 7.The described inclined side 2.1 for enclosing the second cavity 7 and inner support beam 1 support and connection.
In the present invention, inner support beam 1 is welded on single-skin panel covering inside face, inner support beam 1 is connected to form a Nei Shengshi truss that is complete, that close by carrying the first cavity 6 structure and the second cavity 7 structure welding with covering, thus achieve single-skin panel construction car car body peripheral covering and the inner support beam shared capacity of body, reach the object alleviating car body weight.
The content that this specification sheets is not described in detail belongs to the known prior art of professional and technical personnel in the field.
