Abstract
The utility model provides an automobile top cover rear cross member, and belongs to the technical field of automobiles. The automobile top cover rear cross member comprises roof trim installation holes (58), wherein four lightening holes (52, 53, 54 and 55) are formed in the automobile top cover rear cross member in an upper row and in a lower row in an isosceles trapezoid distribution mode, the distance between two adjacent lightening holes (52 and 53) (54 and 55) is no less than 50mm, and the area of each lightening hole is no less than 0.01m2. Compared with the prior art, on the condition that the automobile top cover rear cross member guarantees strength of an automobile top cover assembly is guaranteed, lightening of the automobile top cover assembly is achieved, and the weight of an automobile body assembly is reduced.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of automobile top-cap assembly, relates in particular to a kind of after cross member for the automobile top-cap assembly.
Background technology
In the existing automotive technology, in order to improve the intensity of automobile top-cap assembly, adopt the mode that the material thickness of deep beam and increase top cover outside plate and each deep beam is set at the top cover outside plate usually.For example, name is called: " car roof reinforcement structure ", the patent No. is: 200720124392.8 Chinese utility model patent discloses a kind of car roof and has strengthened structure, its be the car roof rigidity of structure a little less than, yielding central region below is laterally implemented a crossbeam is set.Name is called: " a kind of high-intensity automobile top-cap structure ", the patent No. is: 201120063258.8 Chinese utility model patent discloses a kind of car roof structure, comprises top cover outside plate, top cover front cross rail, top cover center member, top cover after cross member and deep beam.Prior art has also increased the weight of white automobile assembly by when roof panel cross member being set strengthening intensity in top cover assembly, reduced the car load tractive performance.
The utility model content
At the prior art deficiency, 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 cover and rear frame member, comprise ceiling interior trim mounting hole (58), described automobile top cover and rear frame member is offered four lightening holes of two rows (52,53,54,55) according to the arrangement of isosceles trapezoid, described adjacent lightening hole spacing in twos is not less than 50mm, and the area of each lightening hole all is not less than 0.01 ㎡.
In order to increase the intensity of automobile top cover and rear frame member, four lightening holes (52,53,54,55) of offering on the described automobile top cover and rear frame member are the heavy stand hole.
In order further to increase the intensity of automobile top cover and rear frame member, two ends, the described automobile top cover and rear frame member left and right sides are bending projection (50,51).
In order further to increase the intensity of automobile top cover and rear frame member, the midway location of described automobile top cover and rear frame member arranges bending projection (59).
In order further to increase the intensity of automobile top cover and rear frame member, described automobile top cover and rear frame member ceiling interior trim mounting hole (58) is the heavy stand hole.
In order further to alleviate vehicle weight, preferred, the material thickness of described automobile top cover and rear frame member is 0.6mm.
Compared with prior art, the automobile top cover and rear frame member that the utility model provides is offered the two rows lightening hole, select for use thickness be 0.6mm than thin material, effectively alleviated weight.Lightening hole is selected the heavy stand hole for use, and after cross member two ends and centre arrange the bending bulge-structure, have increased strength of parts; The bending projection on the automobile top cover and rear frame member left side is simultaneously as back door hinge left side reinforcement, the bending projection on automobile top cover and rear frame member the right is simultaneously as the right reinforcement of back door hinge, usefulness more than one reduces amount of parts, thereby has further alleviated vehicle weight.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, a kind of automobile top cover and rear frame member comprises ceiling interior trim mounting hole 58, and mounting hole 58 is heavy stand holes.Described automobile top cover and rear frame member 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 the 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 1, two ends, the described automobile top cover and rear frame member left and right sides are bending projection 50 and bending projection 51.The bending projection 51 on the left side is connected with car body top cover after cross member left side reinforced support 57; 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 automobile top cover and rear frame member arranges bending projection 59.
The material thickness of described automobile top cover and rear frame member is 0.6mm, material model DC03.
Adopt technique scheme, (seeing Table 1-2) occupies a clear edge aspect weight, aspect intensity by the automobile reliability evidence of knowing the real situation, any problem does not appear in top cover center member and even whole top cover assembly that the utility model is designed 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 adopts behind the lightening hole and reduces the loss of weight amount of material thickness
