Description
Technical field
The utility model is used for coach body structure design field, and in particular to a kind of tip cap edge of aluminium alloy car
Beam and roof frame structure.
Background technology
At present, as the performance requirement to automobile environment-protection is more and more, the full aluminum technology of bus body is current bus industry
The key technology of urgent need.Top cover side bar is the important component of roof frame structure, existing aluminium alloy bus roof outer skeleton
Structure division can have following three points deficiency：
First, most of top cover assembly still needs the single car gusset structure sluice structure of installation, in order to which gutter channel is pacified
Fill firm, through fixing itself and tip cap edge longeron frequently with countersunk head self threading pin, such structure type destroys roof frame
The bulk strength of assembly；Further, since this mounting structure can not accomplish the mounting plane and tip cap edge longeron curved surface for making gutter channel
Fitting completely, so also increasing the risk of plane leak on gusset glass.
2nd, at present, the side wall pillar of part aluminium alloy bus roof outer side bar and side wall frame is using welding structure, this
Kind connected mode is not only with larger welding pollution but also higher to welding equipment requirement, and aluminium section bar is in welding process
Easily it is deformed, welding quality is poor, and Site Welding inconvenience；And all aluminium alloy bus roof outer side bar of remainder and side
The side wall pillar of skeleton is enclosed using riveted structure, although such a connected mode intensity is good, no deformation tendency, rivet valency
Lattice are more expensive, if batch is higher into production manufacturing cost.
3rd, most of top cover assembly does not have reinforcement structure, particularly the roof frame part above front door and middle door
Lack skeleton strengthening measure, and be in the design process, before car, at middle door the larger position of car upper body stress,
So after using aluminum alloy materials, its body stiffness is markedly less than traditional steel vehicle body, and this will hinder car body of aluminum alloy significantly
Popularization and application.
The content of the invention
A kind of the defects of the utility model is in the presence of above-mentioned prior art, there is provided tip cap edge of aluminium alloy car
