Description
Technical field
The utility model belongs to electric car body technical field of structures, is specifically related to a kind of miniature electric automobile roof front transverse beam.
Background technology
Automotive light weight technology, safety are the important indicators of automotive performance.In existing automotive technology, in order to improve the intensity of automobile top-cap assembly, being typically employed in and top cover outside plate arranging deep beam and increase the thick mode of its material.Which of prior art too increases the weight of body in white while strengthening automobile top-cap assembly intensity, fails to realize the lightweight of automobile.
Utility model content
For prior art Problems existing, the purpose of this utility model is to design the technical scheme providing a kind of miniature electric automobile roof front transverse beam.
Described a kind of miniature electric automobile roof front transverse beam, comprise cross girder and be arranged on the reading lamp mounting bracket in the middle part of cross girder, it is characterized in that described cross girder entirety is middle convex both sides flat structure, described cross girder with its centre symmetry line for the every side of center of symmetry arranges the first lightening hole and the second lightening hole, first negative and positive platform is set between the first described lightening hole and the second lightening hole, the second described lightening hole arranged outside second negative and positive platform, arranges sun shield mounting hole in the first described negative and positive platform and the second negative and positive platform.
Described a kind of miniature electric automobile roof front transverse beam, is characterized in that the length of the second described lightening hole is greater than the first lightening hole.
Described a kind of miniature electric automobile roof front transverse beam, is characterized in that the spacing between the first described lightening hole and the second lightening hole and between two first lightening holes is not less than 70mm, and the first described lightening hole and the area of the second lightening hole are not less than 0.0029m
2.
Described a kind of miniature electric automobile roof front transverse beam, it is characterized in that described cross girder lower edge is provided with one group and beats glue point, the described distance of beating between glue point is not less than 62mm.
Described a kind of miniature electric automobile roof front transverse beam, is characterized in that described cross girder upper limb bilateral symmetry arranges loss of weight breach.
Described a kind of miniature electric automobile roof front transverse beam, is characterized in that described sun shield mounting hole is heavy stand hole.
Described a kind of miniature electric automobile roof front transverse beam, is characterized in that described cross girder material is thick in 0.7mm.
Above-mentioned a kind of miniature electric automobile roof front transverse beam, structure is simple, reasonable in design, by offering the maximized lightening hole of area, loss of weight breach and reducing the weight that cross girder material thickness reduces front cross rail, by cross girder being arranged to middle convex both sides flat structure, and by arranging the structures such as negative and positive platform, make to form the intensity that bending bulge-structure adds front cross rail, by sun shield mounting hole is made the intensity that heavy stand formula adds front cross rail on the upper and lower both sides of cross girder and the right and left.In sum, the utility model, while lightization front cross rail weight, has increased substantially the intensity of front cross rail.

Fig. 2 is that in Fig. 1, A-A analyses and observe enlarged diagram.
In figure: 1-cross girder; 2-reading lamp mounting bracket; 3-first lightening hole; 4-second lightening hole; 5-first negative and positive platform; 6-second negative and positive platform; 7-sun shield mounting hole; 8-loss of weight breach; 9-beats glue point.
Detailed description of the invention
The utility model is further illustrated below in conjunction with Figure of description.
As shown in the figure, a kind of miniature electric automobile roof front transverse beam comprises cross girder 1, and cross girder 1 material is thick is 0.7mm, and cross girder 1 entirety is middle convex both sides flat structures, enhances its intensity.Reading lamp mounting bracket 2 is fixedly installed, for installing reading lamp in the middle part of cross girder 1.Cross girder 1 with its centre symmetry line for the every side of center of symmetry arranges the first lightening hole 3 and the second lightening hole 4, namely 4 lightening holes are set on cross girder 1, two the first lightening holes 3 and two the second lightening holes 4, wherein the length of the second lightening hole 4 is greater than the first lightening hole 3.In order to ensure the intensity of front cross rail, the spacing between the first lightening hole 3 and the second lightening hole 4 and between two first lightening holes 3 is not less than 70mm, and the area of the first lightening hole 3 and the second lightening hole 4 is not less than 0.0029m
2.In order to further proof strength, the first negative and positive platform 5, second lightening hole 4 arranged outside second negative and positive platform 6 is set between first lightening hole 3 and the second lightening hole 4.First negative and positive platform 5 is the boss of relative cross girder 1 with the second negative and positive platform 6.The setting of the first negative and positive platform 5 and the second negative and positive platform 6, makes the irregular tortuosity of cross girder 1 tool, and ensureing slight, is the equal of reinforced rib.Arrange sun shield mounting hole 7 in first negative and positive platform 5 and the second negative and positive platform 6, sun shield mounting hole 7 is specially heavy stand hole.Cross girder 1 lower edge is provided with one group and beats glue point 9, and the distance of beating between glue point 9 is not less than 62mm.Cross girder 1 upper limb bilateral symmetry arranges loss of weight breach 8, reaches the effect of further loss of weight.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change.All various changes done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
