The specific embodiment
As shown in Figure 1, the automobile top-cap assembly comprises automobile top cover outer plate 1, front cross rail 2, center member 3 and after cross member 4.
As shown in Figure 2 and Figure 3, automobile top cover outer plate 1, take the vehicle body fore-and-aft direction as its fore-and-aft direction, a lightening hole 12 is offered in the relevant position that high-mount brake lamp is installed in top cover outside plate 1 rear portion 11, and described lightening hole 12 is also the installation mating holes of described high-mount brake lamp simultaneously.The advantage of doing like this is at narrower automobile top cover outer plate 1 rear portion 11 of Width, and when guaranteeing set loss of weight index, proof strength, can also realize the smooth installation of high-mount brake lamp as far as possible.The preferred rectangle of the shape of lightening hole 12, perhaps other analogous shapes, area is to be not less than 0.009 ㎡ as excellent.
In order to gain in strength, at described automobile top cover outer plate 1 rear portion 11, bending structure 13 is set.As shown in Figure 4, automobile top cover outer plate 1 rear portion 11 arranges and can also make after bending structure 13 the outer postlaminar part 11 of car body top cover as top and the both sides of back door glass 16, the border is installed together with left side wall exterior panel rear portion 14, the outer postlaminar part 15 of right side wall.
As shown in Figure 2 and Figure 3, automobile top cover outer plate 1 arranges bending edges 19 in its front portion, on its border, left and right sides, bending edges structure 17,18 is set, and makes it namely can strengthen top cover outside plate intensity as bending edges, can also be as structure sluice structure.
The material thickness of described automobile top cover outer plate 1 is 0.7mm, can significantly reduce top cover weight.
Shown in Figure 5 is front cross rail 2, and material thickness is 0.7mm, arranges five lightening holes in symmetrical mode on front cross rail 2 rotational symmetry line of centerss: lightening hole 21, lightening hole 22, lightening hole 23, lightening hole 24, lightening hole 25.Spacing is not less than 50mm to above-mentioned lightening hole in twos, each lightening hole area is not less than 0.003 ㎡.For example, these five lightening holes from left to right in twos spacing be followed successively by 149 mm, 56 mm, 56 mm, 149mm, area is followed successively by 0.003 ㎡, 0.003 ㎡, 0.004 ㎡, 0.003 ㎡, 0.003 ㎡.Wherein, the lightening hole 23 offered of midway location is simultaneously as the installation mating holes of indoor front ceiling lamp.As shown in Figure 7, lightening hole 25 is the heavy stand hole, with the lightening hole 21 of lightening hole 25 symmetries be also the heavy stand hole.As shown in Figure 8, lightening hole 24 is the heavy stand hole, with the lightening hole 22 of lightening hole 24 symmetries be also the heavy stand hole.As shown in Figure 9 and Figure 10, the sun shield mounting hole 26 of front cross rail 2 and mounting hole 27 are made the heavy stand pattern.
As shown in Figure 5, for further loss of weight, front cross rail 2 lower edges arrange some glue points 30 of beating, and each dozen glue point 30 distance between any two is not less than 130mm, for example, can be 131mm.Beat and reduce heavy breach 29 between glue point 30 for adjacent two.In order to increase the intensity of front cross rail 2, as shown in figure 10, the lower edge of described front cross rail 2 arranges some reinforced ribs 31.As shown in Figure 8, the both sides up and down of front cross rail 2 are respectively bending projection 32 and bending projection 33.As shown in Figure 6, front cross rail 2 two ends are bending projection 28.
As shown in figure 11, the bending projection 28 at front cross rail 2 two ends, its position is between automobile top cover outer plate assembly 36, left A post inner panel epimere 34 and right A post inner panel epimere 35, the upper surface of bending projection 28 and top cover outside plate assembly 36 are fitted, bending projection 28 lower surfaces and left A post inner panel epimere 34 and right A post inner panel epimere 35 are fitted, and mainly bear from the pressure of top cover outside plate assembly 36 and transmit from left A post inner panel epimere 34 and right A post inner panel epimere 35 the twisting resistance of coming.
Shown in Figure 12 is center member 3, offer four lightening holes with symmetrical arrangement on center member 3 line of centerss: lightening hole 31, lightening hole 32, lightening hole 33, lightening hole 34, described four lightening holes spacing in twos are not less than 50mm, for example, lightening hole from left to right is respectively 66mm, 86mm, 66mm in twos.Each lightening hole area is not less than 0.008 ㎡.As shown in figure 14, lightening hole 33 and other three lightening holes are the heavy stand hole, make the intensity of top cover middle transverse beam intermediate projections part greatly strengthen also having reached simultaneously set loss of weight index.As Figure 13, shown in Figure 16, on center member 3, ceiling interior trim swell fixture mounting hole 39 and mounting hole 40 are the heavy stand hole, make the intensity of top cover middle transverse beam intermediate projections part be enhanced to some extent.As shown in figure 12, described center member is beaten on the glue flange to arrange and is beaten glue point 35 in both sides Shang Xia 3, and glue point 35 distance between any two of beating that homonymy is adjacent is not less than 130mm, up and down described glue point 35 alternative arrangement of beating in both sides.Loss of weight breach 38 is all offered in beating that the homonymy of described center member 3 is adjacent between glue point 35, described loss of weight breach 38 alternative arrangement in both sides, up and down.As shown in Figure 12 and Figure 13, on described center member 3, lower edge arranges some reinforced ribs 41, and the intensity on border, both sides, up and down is strengthened greatly.As Figure 12, shown in Figure 14, described center member Shang Xia 3 both sides be bending projection 37.As Figure 12, shown in Figure 15, described center member 3 two ends, left and right are bending projection 36.The concrete effect of bending projection 36 and bending projection 37 be make top cover middle transverse beam reach up and down border, left and right and intermediate projections partly to form face poor, the intensity of increasing top cover middle transverse beam has been played key role.The material thickness of described center member 3 is 0.6mm.
As Figure 17, Figure 18, Figure 19, Figure 20, shown in Figure 21, after cross member 4 comprises ceiling interior trim mounting hole 58, and mounting hole 58 is heavy stand holes.Described after cross member 4 is offered four lightening holes of two rows according to the arrangement of isosceles trapezoid: lightening hole 52, lightening hole 53, lightening hole 54 and lightening hole 55 are the heavy stand hole.Described four adjacent lightening holes of lightening hole spacing in twos are not less than 50mm, for example, phase from left to right, the distance between adjacent lightening hole is followed successively by 66 mm, 86 mm and 66mm.Each lightening hole area is not less than 0.01 ㎡.
As shown in figure 17, described after cross member 4 two ends, left and right are bending projection 50 and bending projection 51.The bending projection 51 on the left side is connected with the left reinforced support 57 of car body top cover after cross member; The bending projection 50 on the right is connected with the right reinforced support 56 of car body top cover after cross member, jointly as back door hinge reinforcement.
The midway location of described after cross member 4 arranges bending projection 59.
The material thickness of described after cross member 4 is 0.6mm, material model DC03.
Adopt technique scheme, (seeing Table 1-3) occupies a clear edge aspect weight, by the automobile reliability evidence of knowing the real situation, any problem does not appear in the automobile top-cap assembly that the utility model provides in process of the test aspect intensity, and its structural strength satisfies operating needs.
Table 1 is by suitably reducing the thick loss of weight amount of parts material
Table 2 also reduces the thick loss of weight amount of material after adopting lightening hole and beating the glue breach
Table 3 top cover assembly loss of weight amount statistics
