The design of the roof front cross member support panel has been one of the important parts of the vehicle body design.
The structural design of the top cover front beam supporting plate of many motorcycle types in the existing market is unreasonable, the top cover front beam supporting plate and the top cover front beam are welded and then pre-positioned by adopting a local flanging mode, and the mode mainly has the problems that the process is complex, the pre-positioning precision is poor, the top cover front beam is easy to fall off in the fixture positioning process and the like.
Therefore, it is necessary to develop a roof front cross member support plate and a vehicle.
Disclosure of Invention
The utility model aims at providing a top cap front beam backup pad and vehicle can improve the prepositioning precision to the top cap front beam, and can effectively avoid the problem that the top cap front beam drops at the anchor clamps clamping process.
Top cap front beam backup pad, its cross section is the U-shaped, is equipped with the first step face of undercut on the tip that top cap front beam backup pad and top cap front beam are connected one end, is equipped with on this first step face to be used for carrying out prepositioned projection welding bolt to top cap front beam, is equipped with the overlap joint turn-ups of downward sloping in top cap front beam backup pad and the one end that the side wall is connected.
furthermore, a liquid leakage hole is formed in the position, close to the lap joint flanging, of the top cover front cross beam supporting plate.
the lap joint turn-ups are provided with drainage concave ribs extending along the length direction of the top cover front beam, so that the welding of the top cover front beam supporting plate and the A column inner plate is ensured, and the drainage of the electrophoretic fluid is facilitated.
Furthermore, two drainage concave ribs are arranged on the lap joint turnup.
The utility model discloses a vehicle, including top cap front beam, A post inner panel and side wall planking, the both ends of top cap front beam are welded together with the A post inner panel and the side wall planking of corresponding side through a top cap front beam backup pad respectively, top cap front beam backup pad adopts the real utility model the top cap front beam backup pad;
And second step surfaces matched with the first step surfaces are arranged at the end parts of the two ends of the top cover front cross beam, and positioning holes correspondingly matched with the projection welding bolts are arranged on the second step surfaces.
The utility model has the advantages of it is following:
(1) The top cover front cross beam is pre-connected with the left side wall assembly and the right side wall assembly in a pre-positioning mode through the projection welding bolts, so that the pre-positioning precision of the top cover front cross beam is improved, and the problem that the top cover front cross beam falls off in the clamping process of the clamp is effectively avoided;
(2) The mode that the top cover front beam is pre-positioned in a mode that the flange is replaced by the projection welding bolt reduces the stamping forming difficulty of the top cover front beam supporting plate, reduces the stamping process and reduces the development cost of part tools.
