Abstract
The invention relates to a transverse beam-free joggling type vehicle bottom plate assembly which comprises edge beams, longitudinal beams and bottom plates. The transverse beam-free joggling type vehicle bottom plate assembly is characterized in that one side or both sides of the bottom plates are provided with joggling groove structures along the length direction; the bottom plates are connected to form a large bottom plate in a joggling groove connecting way along the longitudinal direction of a vehicle body; the edge beams are connected to the end parts of the bottom plates; and the longitudinal beams are arranged under the bottom plates and connected with the bottom plates. The invention is not provided with transverse beams, does not need the welding between the bottom plates and the transverse beams and reduces the welding deformation and the welding stress of the bottom plate assembly, and the strength and the working reliability of the bottom plate assembly are improved, particularly the vehicle bottom plate made of an aluminum magnesium alloy material has more obvious effect; no harmful gas is generated in the assembly process of the bottom plate assembly, thereby being beneficial to environmental protection; the assembly process is simple, the production efficiency is high, and the manufacture cost is reduced.
Description
Technical field
The present invention relates to a kind of transverse beam-free joggling type vehicle bottom plate assembly, particularly a kind of floor pan assembly device that is used for automobile bodies, auto trailer, railway carriage belongs to the vehicle part field.
Background technology
At present, the floor pan assembly of automobile bodies, auto trailer, railway carriage is to be made by metallic material basically, is welded to each other by side bar, longeron, crossbeam, base plate to form.Side bar, longeron, crossbeam are formed a framed structure and are welded under the base plate, work to support, strengthen base plate.This welded major defect is: in welding process, floor pan assembly easily produces welding deformation, has welding stress, and then influences the intensity and the functional reliability of floor pan assembly, especially the vehicle floor made of aluminium, magnesium alloy materials, its welding influence is more very; In welding process, produce pernicious gas, be detrimental to health, be unfavorable for environmental protection; The welding job amount is big, and production efficiency is low, the manufacturing cost height.
Summary of the invention
The objective of the invention is provides a kind of transverse beam-free joggling type vehicle bottom plate assembly in order to overcome deficiency of the prior art.
The objective of the invention is to realize with the following methods:
The present invention is made up of side bar, longeron, base plate, it is characterized in that: one side or both sides at base plate are provided with tenon groove structure along its length, vertically adopt the tongue-and-groove connection mode to connect into big base plate each other along car body between base plate and base plate, side bar is connected the end of base plate, longeron is located under the base plate, and is connected with base plate.
Advantage of the present invention is: do not have crossbeam, need not base plate and crossbeam is welded to each other, reduced the welding deformation and the welding stress of floor pan assembly, the intensity and the functional reliability of floor pan assembly are improved, especially the car bottom plate made of aluminium, magnesium alloy materials, its effect is more obvious; In the assembling process of floor pan assembly, can not produce pernicious gas, help environmental protection; Simple for assembly process, the production efficiency height has reduced manufacturing cost.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is a transverse sectional view of the present invention;
Fig. 3 is a longitudinal sectional view of the present invention;
Fig. 4 is the cross section structure scheme drawing of side bar;
Fig. 5 is one of cross section structure scheme drawing of base plate;
Fig. 6 be base plate the cross section structure scheme drawing two.
The specific embodiment
With reference to accompanying drawing 1,2,3,4, the present invention is made up of side bar 1, longeron 2, base plate 3.Side bar 1 is useful on the tongue-and-groove 12 that the compartment hinge is installed, the tongue-and-groove 13 that shackle is installed, the Stop structure 14 of side bar 1 restricted base plate 3DOF; There is tongue-and-groove 31 on base plate 3 both sides.The annexation of each part is: base plate 3 vertically adopts tongue-and-groove 31 to be connected with base plate 3 along car body, on side bar 1, be provided with the Stop structure 14 of restriction base plate 3DOF, the end of base plate 3 is plugged in the Stop structure 14 of side bar, side bar 1 is pegged graft with base plate 3, rivet welding, and longeron 2 adopts grafting or rivet welding to be connected with base plate 3.With reference to accompanying drawing 5,6, the tenon groove structure of base plate 3 can be any tenon groove structure that meets requirement of strength.
Claims (2)
1, a kind of transverse beam-free joggling type vehicle bottom plate assembly, form by side bar, longeron, base plate, it is characterized in that: one side or both sides at base plate are provided with tenon groove structure along its length, vertically adopt the tongue-and-groove connection mode to connect into big base plate each other along car body between base plate and base plate, side bar is connected the end of base plate, longeron is located under the base plate, and is connected with base plate.
2, transverse beam-free joggling type vehicle bottom plate assembly according to claim 1 is characterized in that: be useful on tongue-and-groove that the compartment hinge is installed and the tongue-and-groove that shackle is installed on the side bar.
