The utility model content
In order to improve light bus top cover rigidity problem, the utility model provides a kind of improvement structure to be used for the light bus cap structure.
The technical scheme that the utility model adopted is:
A kind of light bus top cover assembly is put, and comprises brace panel in top cover outside plate and the top cover, and brace panel is welded on the top cover outside plate inner face in the said top cover; Improvement is: said top cover outside plate is made up of leading portion and back segment two parts; Leading portion is the following bent plate that is provided with radian, and back segment is a horizontal plate, and it is an integral body that spot welded welding manner overlap joint is adopted for two sections in front and back; Said top cover outside plate is evenly equipped with the vertical U type of six roots of sensation strengthening groove; U type strengthening groove breaks off the section junction in front and back; Preceding U type strengthening groove is located at top cover outside plate leading portion rear portion, and back U type strengthening groove connects whole top cover outside plate back segment;
In the said top cover brace panel by crossbeam be connected longeron and form; Connect the netted shape structure of longeron splicing composition with two between first three root crossbeam is adjacent and be welded on top cover outside plate front interior; Two crossbeams in back are uniformly distributed with and are welded on the outer postlaminar part inner face of top cover.
The position of weld of first three root crossbeam of brace panel is respectively in the said top cover; Preceding first crossbeam is welded under the top cover outside plate leading portion on the bent-up end portion inner face; In second crossbeam be welded on the inner face of the horizontal rear portion of top cover outside plate leading portion, the back the 3rd crossbeam be welded on the top cover outside plate back segment front interior.
In said second crossbeam width be the 3rd crossbeam width in back 2-3 doubly.
The useful technique effect of the utility model is:
1, top cover assembly improves the rigidity of top cover assembly by brace panel two superimposed welding in top cover outside plate and the top cover;
2, top cover outside plate back segment is evenly distributed with 6 U type strengthening grooves that vertically connect, and effectively increases top cover outside plate rigidity;
3, brace panel leading portion crossbeam is different from other vehicle in the top cover; Increased grid frame; In snow load test and vehicle body roll collision, play good rigidity protective effect, show that according to observed data the deflection that increases the network back header is reduced to 7.1mm by original 10.5mm;
4, brace panel is decomposed into a plurality of girder weldings by integral type in the top cover, has promoted stock utilization.
Description of drawings
Fig. 1 is the utility model scheme drawing.
Fig. 2 is the structural representation of brace panel assembly in the top cover.
Fig. 3 is the scheme of installation of top cover assembly.
Fig. 4 is the inside and outside plate joint face scheme drawing of top cover assembly.
Among the figure: top cover outside plate 1, brace panel 2 in the top cover, crossbeam 2.1 connects longeron 2.2, preceding first crossbeam 2.1.1, in second crossbeam 2.1.2, the 3rd crossbeam 2.1.3 in back.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done explanation further through embodiment.
Embodiment:
Referring to Fig. 1 and Fig. 3, the top cover assembly of light bus comprises brace panel 2 in top cover outside plate 1, the top cover.Top cover outside plate 1 is mainly outer covering piece, and the in-to-in structure is formed parcel, realizes the shaping style of car load; Brace panel 2 forms the support frame of top cover in the top cover, guarantees the integral rigidity of top cover assembly.
Top cover outside plate 1 adopts the mode of two weldings, is respectively: top cover outside plate leading portion and top cover outside plate back segment.The dimensional control of section exterior panel is below 1330mm * 1850mm before and after the piecemeal back header, and die length is less than 3000mm, to the requirement reduction of equipment.Top cover outside plate leading portion is the following bent plate that certain radian is arranged, and top cover outside plate back segment is a horizontal plate, and top cover outside plate leading portion overlaps on top cover outside plate back segment, adopts spot welded welding manner to connect.The top cover outside plate is evenly equipped with the vertical U type of six roots of sensation strengthening groove; U type strengthening groove breaks off the section junction in front and back; Preceding U type strengthening groove is located at top cover outside plate leading portion rear portion, and back U type strengthening groove connects whole top cover outside plate back segment.
Referring to Fig. 2, brace panel 2 is made up of nine horizontal strokes, longeron welding in the top cover, comprises that five crossbeams 2.1 are connected longeron 2.2 with four; Wherein preceding first crossbeam 2.1.1, in second crossbeam 2.1.2, the 3rd crossbeam 2.1.3 in back (first three root) connects the netted shape structures of longerons splicing composition with two between any two; Two crossbeams in back are uniformly distributed with and are welded on the outer postlaminar part inner face of top cover.
Preceding first crossbeam 2.1.1 is welded under the top cover outside plate leading portion on the bent-up end portion inner face, in second crossbeam 2.1.2 be welded on the inner face of the horizontal rear portion of top cover outside plate leading portion, the 3rd crossbeam 2.1.3 in back is welded on the top cover outside plate back segment front interior; Formed the main support framework of brace panel in the top cover, can guarantee that top cover is stressed more even.In second crossbeam its width of center that is netted shape structure be 3 times of the 3rd crossbeam width in back.
All leave on the both sides landing edge of nine horizontal strokes of brace panel 2, longeron in the top cover and beat the glue groove, about spacing 100mm.Brace panel is decomposed into a plurality of beam weldings in the top cover, and stock utilization improves.
