The A-pillar upper sections 501 are respectively arranged at the left front end and the right front end of the top cover upper plate 600, the B-pillar upper outer plate 401 is respectively arranged at the left rear end and the right rear end of the top cover upper plate 600, the A-pillar middle connecting plate 502 is connected between the lower ends of the two A-pillar upper sections 501, and the B-pillar middle connecting plate 402 is connected between the lower ends of the two B-pillar upper outer plates 401.
The A-column connecting bracket 500 is arranged at the lower end of the A-column upper section 501 and is used for connecting the A-column lower section, the B-column connecting bracket 100 is used for being fixed with the B-column upper inner plate 200 and the B-column lower section, and the B-column upper inner plate 200 is respectively bonded and fixed with the B-column upper outer plate 401 and the top cover upper plate 600;
the front beam 650 is adhesively fixed to the lower surface of the top cover upper plate 600, and the rear beam 660 is adhesively fixed to the top cover upper plate 600 and the B-pillar upper inner plate 200, respectively.
The top cover upper plate 600, the A-column upper section 501, the A-column middle connecting plate 502, the B-column upper outer plate 401, the B-column middle connecting plate 402, the B-column upper inner plate 200, the front cross beam 650 and the rear cross beam 660 are all carbon fiber pieces; the a-pillar connecting bracket 500 and the B-pillar connecting bracket 100 are light alloy members.
According to the top cover 000 provided by the embodiment of the invention, the top cover upper plate 600, the A-column upper section 501, the A-column middle connecting plate 502, the B-column upper outer plate 401, the B-column middle connecting plate 402, the B-column upper inner plate 200, the front cross beam 650 and the rear cross beam 660 which are made of carbon fibers, and the A-column connecting bracket 500 and the B-column connecting bracket 100 which are made of light alloy (such as aluminum alloy) are adopted, so that the weight of the top cover 000 can be reduced while the strength requirement is met, and the light weight level of the whole vehicle is improved.
Referring to fig. 2, the roof upper 600 for a double door vehicle of the present invention has a sunroof mounting opening 670, and the roof upper 600 may include a roof upper front cross plate 610, a roof upper left longitudinal plate 620, a roof upper rear cross plate 630, and a roof upper right longitudinal plate 640, which are sequentially connected. Specifically, the top cover upper plate front transverse plate 610, the top cover upper plate left longitudinal plate 620, the top cover upper plate rear transverse plate 630 and the top cover upper plate right longitudinal plate 640 enclose a frame structure with the skylight installation opening 670, and the frame structure has higher strength and can provide installation points for the skylight.
Specifically, the roof upper front cross plate 610 and the roof upper rear cross plate 630 are located at the front and rear sides of the sunroof mounting opening 670, respectively, and the roof upper left longitudinal plate 620 and the roof upper right longitudinal plate 640 are located at the left and right sides of the sunroof mounting opening 670, respectively.
The front cross member 650 and the rear cross member 660 are located on the surface of the roof upper 600 facing the vehicle interior space. In an exemplary embodiment, the front cross member 650 is adhesively secured to the top cover upper front rail 610 and abuts the upper end of the A-pillar, and a front box-like cavity is defined between the front cross member 650 and the top cover upper front rail 610. The rear cross member 660 is fixedly bonded to the top cover upper plate rear cross plate 630 and corresponds to the upper end of the B-pillar, and a rear box-shaped cavity is defined between the rear cross member 660 and the top cover upper plate rear cross plate 630. The front and rear cross members 650 and 660 improve the strength of the roof top panel 600.
According to the roof upper panel 600 for the double-door vehicle of the present invention, the strength of the roof upper panel 600 is significantly improved by providing the front cross member 650 and the rear cross member 660, thereby improving the collision performance of the vehicle. Meanwhile, front and rear boxed cavities are formed at the front and rear cross members 650 and 660, respectively, so that the strength of the front and rear portions of the cap-up plate 600 is further enhanced. In addition, the adoption of the bonding and fixing mode can also better adapt to the adoption of light materials such as carbon fiber materials and the like for the top cover upper plate 600.
Referring to fig. 2, the dimension of the roof upper front cross plate 610 in the vehicle length direction is larger than the dimension of the roof upper rear cross plate 630 in the vehicle length direction. In other words, the top cover upper plate front cross plate 610 has a width greater than the top cover upper plate rear cross plate 630. Also, since the front cross member 650 is fixed to the top cover upper plate front cross plate 610 and the rear cross member 660 is fixed to the top cover upper plate rear cross plate 630, the width of the front cross member 650 is preferably greater than the width of the rear cross member 660, as shown in fig. 1 and 2.
Referring to fig. 5, the front beam 650 includes a front beam raised portion 651 and a front beam burring 652 provided at a peripheral edge of the front beam raised portion 651, and the front beam raised portion 651 and the front beam burring 652 are not in the same plane. The front cross member 650 is provided with an adhesive layer, and specifically, the front cross member flange 652 is provided with an adhesive layer, and during assembly, the front cross member flange 652 is adhered and fixed to the top cover upper plate front cross plate 610, so that the front cross member 650 is fixed to the top cover upper plate front cross plate 610. The front beam ridge 651 is hollow, and thus a front box-shaped cavity is defined between the front beam ridge 651 and the top cover upper plate front cross plate 610, which is advantageous in reducing the weight of the front beam 650 and improving the front strength of the top cover upper plate 600.
The front rail flange 652 may include a front rail front flange 6521, a front rail side flange 6522, a front rail rear flange 6523, and a front rail rear flange 6524. Specifically, both ends of the front cross rail front flange 6521 are connected to the front ends of the front cross rail side flanges 6522, respectively, and both ends of the front cross rail rear flange 6523 are connected to the rear ends of the corresponding front cross rail side flanges 6522, respectively, through the front cross rail rear flange 6524.
The widest of the front rail front flange 6521, the front rail side flange 6522, the front rail rear flange 6523 and the front rail rear flange 6524 is the front rail side flange 6522, so that the bonding area of the front rail 650 and the top cover upper plate front cross plate 610 on the side surface is the largest, and the connection is the firmest.
Further, the front cross rail rear flange 6524 is two-step stepped. The front beam rear raised edge 6524 projects out of the front beam rear raised edge 6523 and extends in the direction of the skylight mounting opening 670, so that the strength of the skylight mounting opening 670 is further enhanced, and the strength reduction of the top cover upper plate 600 caused by the skylight mounting opening 670 is greatly improved.
The thickness of the rear cross member 660 is thick in the middle and thin at both ends, and the transition is gentle from the middle to both ends.
