End floor beam soldering member behind the present common microvan, its profile and structure such as Fig. 1 and shown in Figure 2, described back end floor beam soldering member comprises back end floor beam inner panel 1, back end floor beam outside plate 2, back door lock brace panel soldering member 3, left back bumper holder soldering member 4, right back bumper holder soldering member 5 and standby brace panel soldering member 6.Flange is connected with floor spot welding above the 1 back end floor beam inner panel of such back end floor beam soldering member, and termination, left and right sides flange is non-simple flat surface, welds with gusset respectively.Such back end floor beam soldering member all be that single solder joint is connected with the floor, back with gusset, and the quality of butt welding point is very sensitive, and the connection of single solder joint often makes the reduction of body tail intensity, and the collocation of non-simple flat surface is welded, and welding process is poor.
The utility model content
The utility model is in order to overcome above-mentioned the deficiencies in the prior art, and the utility model provides a kind of welding effect good vehicle rear body structure.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of vehicle rear body structure is provided, it comprises back end floor beam inner panel, back end floor beam outside plate, back door lock brace panel soldering member, left back bumper holder soldering member, right back bumper holder soldering member and standby brace panel soldering member, described back end floor beam inner panel is oppositely arranged with back end floor beam outside plate, described back door lock brace panel soldering member, left back bumper holder soldering member, right back bumper holder soldering member and standby brace panel soldering member are arranged on the end floor beam inner panel of back, the lateral ends of described back end floor beam inner panel and back end floor beam outside plate is provided with the termination flange, and the upper end of described back end floor beam inner panel and back end floor beam outside plate is provided with upper overturning respectively.
The scheme that the utility model solves further technical matters is: described termination flange and upper overturning be shaped as flat face.
The scheme that the utility model solves further technical matters is: have the gap between the upper overturning of described back end floor beam inner panel and back end floor beam outside plate.
The scheme that the utility model solves further technical matters is: the inside, gap between the described upper overturning is provided with the rear end cross-beam connecting plate.
The scheme that the utility model solves further technical matters is: described back end floor beam inner panel is provided with spare tyre and dodges structure.
The scheme that the utility model solves further technical matters is: the latter half profile of back end floor beam outside plate is designed to convex closure, makes it to be connected with back end floor beam inner panel, forms cavity body structure.
The scheme that the utility model solves further technical matters is: convex closure upside design reinforced rib.
Compared to prior art, vehicle rear body structure of the present utility model can improve the intensity of parts own, improves rigidity of the vehicle and mode, improves welding process well simultaneously, advantageously promotes production efficiency and quality.
