Vehicle cresting bar mounting structure
Technical field
The utility model belongs to the technical field of automotive body structure, and in particular, the utility model relates to a kind of vehicle cresting bar mounting structure.
Background technology
Vehicle cresting bar is a kind of for decorating the ornamental trimming of roof and gusset panel beating face of weld.As shown in Figure 1, cresting bar 3 of the prior art is generally Z-direction assembling, is fixed in the groove forming after top cover 1 welds with side-wall outer-plate 2, and mounting means generally adopts clamping or bonding.This mounting structure cannot be applicable to Y-direction assembling, and easily cause rainwater on top cover from welding edge directly trickling to the sealing band place of car door upper end, thereby need to carry out encapsulation process, but seal gluing and can have influence on the installation of cresting bar.
Utility model content
The above-mentioned technical matters existing in order to solve prior art, the purpose of this utility model is to provide a kind of vehicle cresting bar mounting structure.
Vehicle cresting bar mounting structure described in the utility model, comprises top cover outside plate, top cover brace panel, side-wall outer-plate and cresting bar; It is characterized in that: the bottom of described top cover outside plate is provided with horizontal flange; The end of described top cover brace panel is provided with horizontal welding edge fit, and is provided with fold bound edge vertically upward in the outer end of described horizontal welding edge fit; The upper end of described side-wall outer-plate is provided with horizontal flange; And the horizontal flange of the horizontal flange of described top cover outside plate, described side-wall outer-plate and the horizontal welding edge fit of top cover brace panel are all arranged on the coboundary place of door sash; The horizontal flange of described top cover outside plate and the horizontal flange of described side-wall outer-plate are welded on respectively on the upper surface and lower surface of horizontal welding edge fit of described top cover brace panel; Described cresting bar is entrenched in described fold bound edge periphery by the first buckle and the second buckle, wherein, described the first buckle is bonded on the horizontal flange upper surface of described fold bound edge top and described top cover outside plate, the upper end of described the second buckle be connected on described the first buckle and with the outside face bonding of described fold bound edge, and extend to the direction that approaches side-wall outer-plate the lower end of described the second buckle.
Vehicle cresting bar mounting structure described in the utility model compared with prior art has following beneficial effect:
Mounting structure of the present utility model, is applicable to Y-direction assembling, can form complete roof drip in lid periphery, and by drainage area is set, can prevent that the rainwater on top cover from directly trickling to car door upper end from welding edge; And form effect like the brim of a hat in lid periphery, improve aesthetic property.
Accompanying drawing explanation

Fig. 2 is the structural representation of the vehicle cresting bar mounting structure described in embodiment 1.
The specific embodiment
Below with reference to embodiment and accompanying drawing, vehicle cresting bar mounting structure described in the utility model is described in further detail.
Embodiment 1
As shown in Figure 2, the vehicle cresting bar mounting structure described in the present embodiment, comprises the bottom 10, side-wall outer-plate 20 and the cresting bar 30 that are made up of top cover outside plate 12 and top cover brace panel 11; The bottom of described top cover outside plate 12 is provided with horizontal flange 13; The end of described top cover brace panel 11 is provided with horizontal welding edge fit 14, and is provided with fold bound edge 15 vertically upward in the outer end of described horizontal welding edge fit 14; The upper end of described side-wall outer-plate 20 is provided with horizontal flange 21; And the horizontal welding edge fit 14 of the horizontal flange 13 of described top cover outside plate 12, the horizontal flange 21 of described side-wall outer-plate 20 and top cover brace panel 10 is all arranged on the coboundary place of door sash; The horizontal flange 13 of described top cover outside plate 12 is welded on respectively on the upper surface and lower surface of horizontal welding edge fit 15 of described top cover brace panel 14 with the horizontal flange 21 of described side-wall outer-plate 20; Described cresting bar 31 is entrenched in described fold bound edge 15 peripheries by the first buckle 32 and the second buckle 33, and installation direction is Y-direction; Wherein, described the first buckle 32 is bonded on horizontal flange 13 upper surfaces of described fold bound edge 15 tops and described top cover outside plate, the upper end of described the second buckle 33 be connected on described the first buckle 32 and with the outside face bonding of described fold bound edge 15, and extend to the direction that approaches side-wall outer-plate 20 lower end of described the second buckle 33.
In structure of the present utility model, cresting bar is entrenched in described fold bound edge periphery by the first buckle and the second buckle, installation direction is Y-direction, thereby can form complete roof drip in lid periphery, and by drainage area is set, can prevent that the rainwater on top cover from directly trickling to car door upper end from welding edge; And form effect like the brim of a hat in lid periphery, improve aesthetic property.
In addition, the fold flange height that adopts roll-in mode to form is lower, and welding space abundance, can reduce to very little by the width of welding edge; Guarantee, after the assembling of cresting bar, to accomplish minimum towards the bulge quantity of body exterior, provide location, the stability of the welding of assurance also to the welding of top cover and gusset simultaneously.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
