Abstract
The utility model relates to a rear floor skeleton structure of a passenger car, which comprises multiple cross beams, multiple longitudinal beams and multiple vertical beams, wherein the cross beams are connected together through the longitudinal beams and vertical beams and form a stair shape; one end of the rear floor skeleton is connected with a rear tail skeleton; the two sides of the rear floor skeleton are connected with a side wall skeleton. The rear floor skeleton structure is characterized by also comprising multiple first connecting pieces, wherein the connection between the cross beams and the longitudinal beams and the connection between the cross beams and the vertical beams are both fixedly riveted through the first connecting pieces. In the rear floor skeleton structure, no bent beams but straight beams are adopted, the manufacturing process is simple, and the production efficiency is high; a closed triangular rigid bearing framework structure is formed by reinforced inclined struts, diamond deformation is not easily caused, the stress distribution is uniform, and the structural stability is good.
Description
Technical field
The utility model belongs to the bus body technical field, relates to a kind of floor skeleton structure, relates to particularly a kind of rear floor frame structure of passenger vehicle.
Background technology
The floor skeleton structure of present domestic traditional passenger vehicle is to adopt steel structure or aluminium alloy extrusions skeleton, forms through the combination welding, and welding deformation is relatively large, and the smog that produces during welding, dust cause the production on-site environment inclement condition.General passenger vehicle rear floor frame is comprised of rear floor crossmember, rear floor vertical beam and rear longitudinal floor beam, be welded to connect by rear longitudinal floor beam, rear floor vertical beam between rear floor crossmember, form step-like, do not take any other strengthening measure, the bulk strength of such rear floor frame is inadequate, especially in fuel cell is arranged on integral new-energy passenger on rear floor frame, the rear floor structure undercapacity, easily cause failure distortion together with the side wall frame that connects with rear floor and rear wall frame, reduced the safety of vehicle body.
There is no in prior art and have simultaneously that welding pollutes, frame strength is high, Stability Analysis of Structures, can make vehicle body deadweight weight-saving bus body rear floor frame structure.
The utility model content
The purpose of this utility model is to provide the bus body rear floor frame structure that a kind of quality is light, welding pollutes, structural strength is stable, production efficiency is high, the deficiency that exists to overcome existing traditional bus deck skeleton.
The technical solution adopted in the utility model is: a kind of bus body rear floor frame structure, comprise a plurality of crossbeams, a plurality of longeron and a plurality of vertical beam, described crossbeam is linked together by longeron and vertical beam, and form stepped, described rear floor frame one end is connected with rear stern frame, the rear floor frame both sides are connected with side wall frame, it is characterized in that: also comprise a plurality of the first attaching partss; Being connected between described crossbeam and longeron, crossbeam and vertical beam is all fixing by the first attaching parts riveted joint.
Preferably, described the first attaching parts is " L " shape.
Preferably, the material of described crossbeam, longeron and vertical beam is aluminium.
Preferably, be provided with a plurality of reinforcement diagonal braces between described close two crossbeams of rear stern frame.
Further preferred, described reinforcement diagonal brace is fixed by the second attaching parts and the 3rd attaching parts and riveting transverse beam.
Further preferred, described the second attaching parts is " V " shape; The cross section of the 3rd attaching parts is " n " shape, and has four faces.
Further preferred, the material of described reinforcement diagonal brace is aluminium.
Preferably, between being connected between described rear floor frame and rear stern frame, rear floor frame both sides and side wall frame be connected all fixing by the first attaching parts riveted joint.
The beneficial effects of the utility model are: rear floor frame adopts aluminium, and be all that straight beam does not have camber beam, manufacture craft is easy, production efficiency is high, alleviate simultaneously workman's labour intensity, and have that lightweight, long service life, anti-inclination, torsion capacity are strong, the fuel economy high; Be provided with a plurality of reinforcement diagonal braces near between two crossbeams of rear stern frame, form thus closed triangle rigidity bearing frame structure, be not easy to produce diamonding, distribution of force is even, structural stability is good, especially its deflection is also less in the integral new-energy passenger that fuel cell is installed, and can not cause the being damaged deformation of adjacent side wall frame and rear wall frame, has guaranteed the body structure safety; Connection mode all connects fixing by the first attaching parts, the second attaching parts riveting or the 3rd attaching parts, the frame welding connection mode of abandoning tradition has avoided welding to pollute, and quick for installation, simple to operate, installation effectiveness is high.

The specific embodiment
As shown in Figure 1 to Figure 3, a kind of bus body rear floor frame structure comprises a plurality of crossbeams 1, a plurality of longeron 2 and a plurality of vertical beam 3, and the material of crossbeam 1, longeron 2 and vertical beam 3 is aluminium, is specially the aluminium section bar square tube; Crossbeam 1 is transversely fixing with a plurality of longeron 2 riveted joints by first attaching parts 4 of " L " shape, and the vertical upper of crossbeam 1 fixed by the first attaching parts 4 and a plurality of vertical beam 3 riveted joints, and makes rear floor frame stepped; Rear floor frame one end and rear stern frame are fixing by the first attaching parts 4 riveted joints, and rear floor frame both sides and side wall frame are also fixing by the first attaching parts 4 riveted joints; Described the first attaching parts 4 is the aluminum corner brace of " L " shape; Be provided with a plurality of reinforcement diagonal braces 5 near between two crossbeams 1 of rear stern frame, strengthening diagonal brace 5 fixing with crossbeam 1 riveted joint by the second attaching parts 6 and the 3rd attaching parts 7; The material of described reinforcement diagonal brace is aluminium, is specially the aluminium section bar square tube.The second 6 of connections are " V " shape, and its material is aluminium.
As shown in Figure 4, the cross section of the 3rd attaching parts 7 is " n " shape, and has four faces, and its material is aluminium.During installation, first that the 3rd attaching parts 7 is fixing with crossbeam 1 riveted joint, and make " n " shape outwardly, then will strengthen " n " shape recess that diagonal brace 5 is enclosed within the 3rd attaching parts 7, rivet and fix will strengthen diagonal brace 5 and the 3rd attaching parts 7.
The whole of the disclosed bus body rear floor frame of the utility model structure employing are that straight beam does not have camber beam, and manufacture craft is easy, and production efficiency is high; Form closed triangle rigidity bearing frame structure by strengthening diagonal brace, be not easy to produce diamonding, distribution of force is even, and structural stability is good.
