Description
Technical field
The invention belongs to vehicle body field engineering field, specifically, relate to a kind of top cover and weld assembly structure with gusset.
Background technology
The automobile of current Load luggage frame, when adopting baggage rack mounting support structure, top cover welding assembly welds assembly with gusset and this support lap-joint panel beating number of plies is many, and may occur five laminates or six laminates, current automobile primary will adopt two kinds of welding manners to weld:
1. adopt traditional inner panel quit a post and thus leave it vacant spot welding, this kind of mode easily occurs that not prison welding is solid, and occur rosin joint, not prison welding is solid, affects performance and the mode of body in white.
2. adopt two to protect weldering welding, after car body has welded, adopted by baggage rack mounting bracket two to protect weldering welding, this kind of mode has had very high requirement to welding process, need increase a jig, affect welding speed, has welded rear solder joint sanding operation difficulty.
Summary of the invention
For solving above technical matters, a kind of top cover of the present invention is the object of the present invention is to provide to weld assembly structure with gusset, solve solder joint when adopting spot-welded insecure, easily there is rosin joint, spot pitch is excessive, welding operation difficulty, the problem that polishing is inconvenient, effectively raises performance and the mode of body in white.
The present invention seeks to realize like this: a kind of top cover welds assembly structure with gusset, comprise top cover, luggage mounting bracket, side-wall outer-plate, A-pillar upper reinforcing plate, inner panel six parts on neutrality column back head roof rail and A-pillar, described luggage mounting bracket, top cover, side-wall outer-plate, the connecting portion of A-pillar upper reinforcing plate is arranged in order from inside to outside, the connecting portion of described neutrality column back head roof rail and A-pillar is all positioned at the outside of described A-pillar upper reinforcing plate, its key is: described top cover is provided with skylight ring stiffener, the edge of described ring stiffener is provided with welding block, this welding block is between the connecting portion and side-wall outer-plate connecting portion of described top cover, on described A-pillar, the connecting portion of inner panel is provided with the first plug welding hole, the corresponding described welding block of described A-pillar upper reinforcing plate is provided with welding block mounting groove, this mounting groove is provided with the second plug welding hole, described A-pillar upper reinforcing plate is fixed by the second plug welding hole and described side-wall outer-plate, corresponding described first plug welding hole of described A-pillar upper reinforcing plate is provided with the 3rd plug welding hole, corresponding described second plug welding hole of connecting portion of described neutrality column back head roof rail has breach, described A-pillar upper reinforcing plate is welded and fixed by the connecting portion of the 3rd plug welding hole and the first plug welding hole and described side-wall outer-plate.
On above-mentioned A-pillar upper reinforcing plate, neutrality column back head roof rail and A-pillar, inner panel correspondence is provided with bolt fixing hole, and on described A-pillar upper reinforcing plate, neutrality column back head roof rail and A-pillar, inner panel is bolted to connection.
Above-mentioned breach is in falling isosceles trapezoid, the equal arc transition of corner angle of this breach.Beneficial effect:
A kind of top cover of the present invention welds assembly structure with gusset, and solve solder joint when adopting spot-welded insecure, easily occur rosin joint, spot pitch is excessive, welding operation difficulty, and the problem that polishing is inconvenient, effectively raises performance and the mode of body in white.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the invention will be further described.
Embodiment:
As shown in Figure 1,2 and 3: a kind of top cover welds assembly structure with gusset, be made up of inner panel 6 six parts on top cover 1, luggage mounting bracket 2, side-wall outer-plate 3, A-pillar upper reinforcing plate 4, neutrality column back head roof rail 5 and A-pillar, as shown in Figures 4 and 5, the connecting portion of described luggage mounting bracket 2, top cover 1, side-wall outer-plate 3, A-pillar upper reinforcing plate 4 is arranged in order from inside to outside, the connecting portion of described neutrality column back head roof rail 5 and A-pillar is all positioned at the outside of described A-pillar upper reinforcing plate 4
As Fig. 1, shown in 2 and 3, described top cover 1 is provided with skylight ring stiffener 7, the edge of described ring stiffener 7 is provided with welding block 8, this welding block 8 is between the connecting portion and side-wall outer-plate 3 connecting portion of described top cover 1, on described A-pillar, the connecting portion of inner panel 6 is provided with the first plug welding hole 6a, the corresponding described welding block 8 of described A-pillar upper reinforcing plate 4 is provided with welding block mounting groove 4a, this mounting groove 4a is provided with the second plug welding hole 4b, described A-pillar upper reinforcing plate 4 is fixed by the second plug welding hole 4b and described side-wall outer-plate 3, the corresponding described first plug welding hole 6a of described A-pillar upper reinforcing plate 4 is provided with the 3rd plug welding hole 4c, the corresponding described second plug welding hole 4b of connecting portion of described neutrality column back head roof rail 5 has breach 5a, described A-pillar upper reinforcing plate 4 is welded and fixed by the connecting portion of the 3rd plug welding hole 4c and the first plug welding hole 6a and described side-wall outer-plate 3.
