Abstract
The invention provides a structure of the back part of a top cover of a car, which comprises a top cover, a reinforcing plate of a back transverse beam, a back transverse beam and a reinforcing plate of a back door hinge. A welding edge at the end of the top cover is welded and connected at the position of the middle lower part of the reinforcing plate of the back transverse beam, the lower part of the reinforcing plate of the back transverse beam passes by the welding edge at the end of the top cover and turns over outwards to form a lower welding edge, and the inner side of the reinforcing plate of the back transverse beam is welded with the back transverse beam by an upper welding edge and the lower welding edge; and a hollow cavity structure is respectively encircled between the back part of the top cover and the reinforcing plate of the back transverse beam and between the reinforcing plate of the back transverse beam and the back transverse beam. The top cover is provided with an inward concave face at an area in which an installation hole of the hinge is arranged, the joint face of the installation face of the hinge is formed, the inner side of the concave face is jointed and welded with the reinforcing plate of the back transverse beam, and the inner side of the reinforcing plate of the back transverse beam is welded with the reinforcing plate of the back door hinge. By the structure, the torsional rigidity of the area of a door frame of a back door is effectively reinforced, an exposed type hinge can be locally hidden, the attractive appearance of the car at the position is kept, and the structure is simple and practical.
Description
Technical field
The present invention relates to the auto body technical field, be specifically related to a kind of structure of back part of top cover of vehicle.
Background technology
Back part of top cover of car is to connect with the weld all around of vehicle body left and right sides, and structure of back part of top cover mainly plays the effect of the torsional stiffness that improves vehicle body tailgate doorframe.For the car that adopts glass backdoor, its mounting means and common vehicle have bigger difference, to the requirement of the torsional stiffness in the tailgate doorframe zone car height than common tailgate, if the common structure of back part of top cover of employing, are difficult to satisfy the installation requirement of glass backdoor.In addition, it is exposed adopting its tailgate installation hinge of car of glass backdoor, relatively influences outward appearance.
Summary of the invention
The present invention proposes a kind of structure of back part of top cover of car, and this structure of back part of top cover can solve the relatively poor problem of tailgate doorframe zone torsional stiffness, and can locally hide exposed hinge, and is simple and practical.
Technical solution of the present invention is as follows:
A kind of structure of back part of top cover of car comprises top cover, is positioned at after cross member, after cross member brace panel and the backdoor hinge brace panel of back part of top cover inboard.
Between described top cover and after cross member, be welded to connect the after cross member brace panel, formed a welding integral, be provided with hinge mounting hole in the both sides of described welding integral.The terminal welding edge of described top cover is welded to connect the position, middle and lower part at the after cross member brace panel, the bottom of after cross member brace panel is walked around the terminal welding edge of top cover and is turned up and forms the bottom welding edge, after cross member brace panel inboard welding edge and after cross member welding by the upper and lower.Between back part of top cover and after cross member brace panel, and all surround cavity structure between after cross member brace panel and the after cross member.By between top cover and after cross member, increasing the after cross member brace panel, and make between back part of top cover and after cross member brace panel, after cross member brace panel and the after cross member and surround cavity structure, can effectively increase the torsional stiffness of tailgate doorframe upper area.
Further, top cover has inside concave surface in the zone that hinge mounting hole was located at, form the hinge face binding face, the cooresponding outer convex surface of the inboard of its described concave surface and after cross member brace panel is fitted and is welded, and at the inboard of after cross member brace panel welding backdoor hinge brace panel.Adopt said structure, convenient an installation for backdoor hinge provides a kind of brand new mounting means, can make hinge be installed in this concave surface position, by partial occlusion, do not influence the car load outward appearance; In addition, owing to have top cover, top cover after cross member brace panel and three layers of welded structure of backdoor hinge brace panel herein, can guarantee the intensity of hinge installation place; Also have the after cross member brace panel this be formed with cooresponding outside convex surface, further increased the cavity between after cross member and the after cross member brace panel like this in this zone, make the torsional stiffness of after cross member brace panel be able to further increase.The cavity of after cross member and after cross member brace panel and left and right sides gusset are excessively whole, have improved the car load torsional stiffness, under the prerequisite that guarantees outward appearance, have reduced technology difficulty.
As seen, adopt the present invention to propose structure of back part of top cover of car and make that tailgate doorframe zone torsional stiffness is effectively strengthened, and can locally hide exposed hinge, the maintenance car is attractive in appearance, simple and practical this position.

The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, this structure of back part of top cover comprises top cover 1, after cross member brace panel 2, after cross member 3, backdoor hinge brace panel 4, and they are whole blanked part.Between top cover 1 and after cross member 3, be welded to connect after cross member brace panel 4, form a welding integral, be provided with hinge mounting hole 5 in the both sides of welding integral.Welding between top cover 1, after cross member brace panel 2 and the after cross member 3 is closed: the terminal welding edge 11 of top cover is welded to connect the position, middle and lower part at after cross member brace panel 2, the bottom of after cross member brace panel 2 is walked around the terminal welding edge 11 of top cover 1 and is turned up and forms bottom welding edge 21, and after cross member brace panel 2 inboards are welded to connect with after cross member 2 by top welding edge 22 and bottom welding edge 21.Between top cover 1 and after cross member brace panel 2, and surround cavity structure A between after cross member brace panel 2 and the after cross member 3.Top cover 1 has inside concave surface 12 in the zone that hinge mounting hole 5 is located at, form the hinge face binding face, the projecting surface of the inboard of its concave surface and after cross member brace panel 2 correspondence positions is fitted and is welded, and at the inboard of after cross member brace panel 2 welding backdoor hinge brace panel 4.
Their sequence of welding is that after cross member brace panel 2, after cross member 3 weld with top cover 1 after welding with backdoor hinge brace panel 4 again.
