Description
Technical field
The utility model belongs to body of a motor car manufacture more particularly to a kind of automobile top cover and side wall assembly structure.
Background technique
At present in body of a motor car manufacture, such as Fig. 7 to Fig. 9, top cover assembly is by top cover outside plate and roof bow assembly, crossbeam
It is connect with outer board spot welding.Side wall assembly is made of side-wall outer-plate, stiffening plate and inner panel three-decker.Top cover assembly and side wall assembly
After conjunction is welded into white body assembly, the weldering of 5 laminates is formed in the position of roof bow, as shown in figure 9, in the part of not roof bow
Also the welding of 4 laminates is formed.The 5 laminates weldering of this structure causes welding difficulty, desoldering, not prison welding and other issues.In order to keep away
Exempt from the weldering of 5 laminates, the matching of top cover assembly and side wall assembly improves are as follows: in the position of not roof bow, side-wall inner-plate snaps a little
Notch is avoided, three layers of top cover outside plate, side-wall outer-plate, side wall stiffening plate spot welding are made；In the position for having roof bow, to guarantee vehicle body
Intensity and vehicle body sealing, side-wall outer-plate, side-wall inner-plate snap an evacuation notch, make top cover outside plate, roof bow, side wall stiffening plate
Three layers of spot welding.In the position of roof bow, side-wall outer-plate, side-wall inner-plate evacuation notch it is different according to the position of roof bow and
It is different.The welding sequence of top cover assembly and side wall assembly structure is:
(1) roof bow and top cover outside plate are welded as a top cover welding assembly；
(2) side-wall outer-plate, side wall stiffening plate, side-wall inner-plate are welded as a side wall welding assembly；
(3) then, it is a white body assembly that top cover welding assembly and side wall welding assembly, which close weldering,.
Existing bridging arrangement has the following disadvantages:
When welding region is 5 layers of metal plate, there are the welding defects such as not prison welding, rosin joint, influence vehicle body integral strength and vehicle
Body quality.
To ensure weld strength, spot welding requires metal plate no more than three layers, the welding of such structure side-wall outer-plate and inner panel
Evacuation notch can be adjusted with the adjustment of roof bow position, cause cutting for various state of side wall, side-wall outer-plate and inner panel
Side difficulty in process, development cycle are long, at high cost.Meanwhile there are poorly sealed risk, vehicle body sealings for side-wall outer-plate gap position
There are hidden danger for property.

Connection side and the roof bow it is fixed, the top cover outside plate and the side-wall outer-plate are fixed.
Further, the connection side of the side wall stiffening plate is connect with the roof bow spot welding.
Further, the connection side of the side wall stiffening plate is fixedly connected with the roof bow by screw.
Further, the connection side of the side wall stiffening plate is Nian Jie with the roof bow.
Further, the top cover outside plate is connect with the side-wall outer-plate and side wall stiffening plate spot welding.
Further, the side-wall inner-plate is equipped with evacuation notch in the spot welding junction.
Further, the top cover outside plate is Nian Jie with the side-wall outer-plate.
The beneficial effects of the utility model are: roof bow is directly connected to side wall stiffening plate, keep overall structure securely steady
It is fixed；Avoid 5 layers of weldering；The overlap joint plane of side-wall outer-plate and top cover outside plate is a complete plane, avoids opening in side-wall outer-plate many places
If avoiding notch, side-wall outer-plate trimming technology is simpler, and vehicle body leakproofness is also guaranteed；) roof bow and side wall overlap joint
Mode is more flexible；The position of roof bow can be according to adjustment before and after the arrangement of different automobile types, but does not influence the state of side wall, makes
Side wall state is less, to reduce development cycle and cost.
The utility model is described in detail with reference to the accompanying drawings and examples.
