The utility model content
Not enough for prior art, the technical problems to be solved in the utility model is under the prerequisite that guarantees automobile top-cap assembly intensity, to realize the lightweight of automobile top-cap assembly, reduction body in white assembly weight.
In order to solve the problems of the technologies described above, the technical scheme that the utility model provides is:
A kind of automobile top-cap center member, comprise ceiling interior trim swell fixture mounting hole (39,40), offer four lightening holes (31,32,33,34) with symmetrical arrangement on automobile top-cap center member line of centers, described lightening hole (31,32,33,34) spacing in twos is not less than 50mm, and each lightening hole area is not less than 0.008 ㎡.
In order to increase the intensity of automobile top-cap center member, the lightening hole of offering on described automobile top-cap center member (31,32,33,34) is the heavy stand hole.
In order to increase the intensity of automobile top-cap center member, on described automobile top-cap center member, ceiling interior trim swell fixture mounting hole (39,40) is the heavy stand hole.
Preferably, both sides, described automobile top-cap center member up and down are beaten to arrange on the glue flange and are beaten glue point (35), and glue point (35) distance between any two of beating that homonymy is adjacent is not less than 130mm, described glue point (35) alternative arrangement of beating in both sides, up and down;
For further expendable weight, loss of weight breach (38) is all offered in beating that the homonymy of described automobile top-cap center member is adjacent between glue point (35), the up and down described loss of weight breach in both sides (38) alternative arrangement.
In order further to increase the intensity of automobile top-cap center member, on described automobile top-cap center member, lower edge arranges some reinforced ribs (41).
In order further to increase the intensity of automobile top-cap center member, both sides, described automobile top-cap center member up and down are bending projection (37).
In order further to increase the intensity of automobile top-cap center member, two ends, described automobile top-cap center member left and right are bending projection (36).
Preferably, the material thickness of described automobile top-cap center member is 0.6mm.
Compared with prior art, the automobile top-cap center member that the utility model provides alleviates component weight in the situation that alleviate to maximize in proof strength, realizes the lightweight of automobile top-cap assembly.

The specific embodiment
As shown in Figure 1, a kind of automobile top-cap center member, offer four lightening holes with symmetrical arrangement on heart line therein: 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 3, 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 Fig. 2, shown in Figure 5, on the automobile top-cap center member, 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 1, both sides, described automobile top-cap center member up and down are beaten to arrange on the glue flange and are beaten glue point 35, and glue point 35 distance between any two of beating that homonymy is adjacent is not less than 130mm, described glue point 35 alternative arrangement of beating in both sides, up and down.Loss of weight breach 38 is all offered in beating that the homonymy of described automobile top-cap center member is adjacent between glue point 35, described loss of weight breach 38 alternative arrangement in both sides, up and down.As shown in Figure 1 and Figure 2, on described automobile top-cap center member, lower edge arranges some reinforced ribs 41, and the intensity on border, both sides, up and down is strengthened greatly.As Fig. 1, shown in Figure 3, both sides, described automobile top-cap center member up and down are bending projection 37.As Fig. 1, shown in Figure 4, two ends, described automobile top-cap center member 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 automobile top-cap center member is 0.6mm.
Adopt technique scheme, (seeing Table 1-3) occupies a clear edge aspect weight, aspect intensity by the automobile reliability evidence of knowing the real situation, any problem does not appear in the top cover middle transverse beam that the utility model is designed and even whole top cover assembly in process of the test, 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 automobile top-cap assembly loss of weight amount statistics
