Description
Technical field
Field is manufactured the utility model relates to car and its parts, more specifically a kind of car aluminium
The connection structure enclosed before and after alloy head cover and steel skeleton.
Background technology
In today that integral new-energy passenger industry rapidly develops, the quality size of vehicle greatly affects energy consumption of vehicles and electricity
Pond course continuation mileage, the lightweight of vehicle body are always the important topic of major automobile vendor's research.The advantage of all aluminium alloy vehicle body exists
It is low obvious to drop weight in the density using aluminum material, but the intensity of vehicle stress larger part is again below steel skeleton, and
Full aluminium integral vehicle cost is higher；The structure of aluminum-steel hybrid vehicle body is that seeks a balance from lightweight, intensity, cost three
Point.Shown according to real vehicle data：Only roof frame and covering use aluminium alloy, and drop, which weighs about, accounts for the 40% of all-aluminium body drop weight, at
This but only accounts for one of five parts, and the key point intensity of vehicle is effectively ensured, and is reflected its " cost performance ".But steel, aluminium can
Weldability is poor, and equipment investment is big, of high cost, complex process, and under production restriction, the connection of general steel aluminium uses riveting process.
Utility model content
Disclosed by the utility model is the connection structure enclosed before and after a kind of passenger carriage aluminum alloy head cover and steel skeleton, main mesh
Be overcome deficiencies of the prior art and disadvantage.
The technical solution adopted in the utility model is as follows：
The connection structure enclosed before and after a kind of passenger carriage aluminum alloy head cover and steel skeleton, including steel rectangular tube and aluminum rectangle pipe, institute
It states steel rectangular tube to be in contact with aluminum rectangle pipe, and the steel rectangular tube offers several along the steel, aluminium on its non-contact face
The axial single side circular hole of the contact surface of rectangular tube fits through a rivet in the single side circular hole, and the rivet is by the aluminum rectangle pipe
It is mutually riveted on steel rectangular tube on the contact surface of the two；The bottom of the steel rectangular tube be also welded with it is several bury iron auxiliary member, should
The perpendicular setting of contact surface of the horizontal plane and the steel, aluminum rectangle pipe of iron auxiliary member is buried, and this buries iron auxiliary member and extends to institute
The bottom margin of aluminum rectangle pipe is stated, and passes through rivet and the aluminum rectangle pipe mutually fixed riveting setting.
Further, the iron auxiliary member that buries has two pieces, is symmetrical set respectively in the both sides of the steel rectangle bottom of the tube.
Further, a diameter of φ 30- φ 45mm of the single side circular hole.
Further, a diameter of φ 30mm of the single side circular hole.
Further, the diameter of the single side circular hole is more than the end diameter of riveting gun used in the rivet.
By the above-mentioned description to the utility model it is found that compared to the prior art, the utility model has the advantage of：
The utility model during the installation process, is enclosed by front and back with after head cover assembling in place, riveting gun is put in single side hole, will
Steel, aluminum rectangle pipe phase-contact surface be riveted together, then again the bottom of steel rectangle bottom of the tube embedded iron and head cover aluminum rectangle pipe
Face is riveted together, and to make steel, aluminum rectangle pipe are reliably connected in orthogonal both direction, avoids rivet unidirectionally by excessive
Shearing force.Not only intensity is good for the structure of the utility model, but also convenient for assembling, meanwhile, in head cover exterior skin and interior decorative plate of top cover
Region is rivet, buries the protrusions such as iron, does not influence the installation of inner and outer decorative parts.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the structural schematic diagram that the steel of the utility model, aluminum rectangle pipe are connected.
Fig. 3 is the cross-sectional view of the utility model.
Specific implementation mode
Illustrate with reference to the accompanying drawings to further explain specific embodiment of the present utility model.
As shown in Figure 1 to Figure 3, the connection structure enclosed before and after a kind of passenger carriage aluminum alloy head cover and steel skeleton, including steel rectangle
Pipe 1 and aluminum rectangle pipe 2, the steel rectangular tube 1 are in contact with aluminum rectangle pipe 2, and the steel rectangular tube 1 opens up on its non-contact face
There are several along the steel, aluminum rectangle pipe（1、2）Contact surface axial single side circular hole 3, fit through in the single side circular hole 3
The aluminum rectangle pipe 2 is riveted on 1 phase of steel rectangular tube on the contact surface of the two by one rivet 4, the rivet 4；The steel rectangular tube 1
Bottom be also welded with it is several bury iron auxiliary member 5, this buries the horizontal plane of iron auxiliary member 5 and the steel, aluminum rectangle pipe（1、2）Contact
The perpendicular setting in face, and this buries iron auxiliary member 5 and extends to the bottom margin of the aluminum rectangle pipe 2, and pass through rivet 4 and the aluminium
2 phase of rectangular tube fixes riveting setting.
Further, the iron auxiliary member 5 that buries has two pieces, is symmetrical set respectively the two of 1 bottom of steel rectangular tube
Side.
Further, a diameter of φ 30- φ 45mm of the single side circular hole 3.
Further, a diameter of φ 30mm of the single side circular hole 3.
Further, the diameter of the single side circular hole 3 is more than the end diameter of riveting gun used in the rivet 4.
The utility model during the installation process, is enclosed by front and back with after head cover assembling in place, and riveting gun is put in single side circular hole,
The phase-contact surface of steel, aluminum rectangle pipe is riveted together, then again steel rectangle bottom of the tube embedded iron and head cover aluminum rectangle pipe
Bottom surface is riveted together, and to make steel, aluminum rectangle pipe are reliably connected in orthogonal both direction, rivet is avoided unidirectionally to receive
Big shearing force.Not only intensity is good for the structure of the utility model, but also convenient for assembling, meanwhile, in head cover exterior skin and head cover interior trim
Plate region is rivet, buries the protrusions such as iron, does not influence the installation of inner and outer decorative parts.
