Abstract

The invention relates to a vehicle body part, in particular to a downwards sliding groove of a vehicle middle slide door. The downwards sliding groove comprises a lower guide rail, a downwards sliding groove lower plate, a downwards sliding groove upper cover plate and a downwards sliding groove front cover plate, wherein the downwards sliding groove upper cover plate is welded on the top face of the lower guide rail; the cross section of the lower guide rail is U-shaped; the downwards sliding groove upper cover plate is extended to the rear end of the lower guide rail from the front end of the lower guide rail and covers the lower guide rail; the upper edge of the downwards sliding groove lower plate is welded on the lower surface of the downwards sliding groove upper cover plate; and a reinforcing connecting plate is welded on the outer side face of the downwards sliding groove lower plate. After the downwards sliding groove is connected with a vehicle body, a middle slide door is smoothly opened and closed, and the middle slide door can be prevented from dropping down.

Description

Slide gliding groove in the automobile

Technical field

The present invention relates to automobile body components, particularly slide gliding groove in the automobile.

Background technology

The middle slide of commercial car is switch swimmingly, directly has influence on the quality of commercial car quality, and middle slide gliding groove then is slide switch one of critical component smoothly in the influence.Like Fig. 4, shown in Figure 5, the middle slide gliding groove of existing automobile is made up of lower guideway 3, gliding groove lower plate 1, gliding groove upper cover plate 4 and gliding groove front shroud 5, and the cross section of lower guideway includes the U-shaped structure, and this U-shaped structure is used for limiting the trend of slide directive wheel; The cross section of gliding groove lower plate is step, and a step end face wherein is used for supporting the scroll wheel of slide; The gliding groove upper cover plate is welded on the lower guideway end face; Be positioned at the lower guideway front end; The upper edge overlap joint of the lower edge of lower guideway and gliding groove lower plate is welded into one; The gliding groove front shroud is positioned at the gliding groove front end, and it is welded between gliding groove lower plate and the gliding groove upper cover plate, with the front end closed-end of middle slide gliding groove.

The middle slide gliding groove of this kind structure since be with lower guideway directly and the gliding groove lower plate weld; After welding, be prone to make lower guideway to produce distortion; And gliding groove is to weld through lower guideway and floor with being connected of vehicle body; And weld through gliding groove front shroud and longeron and to realize, this not only causes lower guideway to produce welding deformation easily, and makes the bonding strength of gliding groove and vehicle body lower; The slide switch has some setbacks in so not only causing easily, and because the bearing strength of the gliding groove centering slide phenomenon that slide drops in lower the appearance.

Summary of the invention

The purpose of this invention is to provide slide gliding groove in a kind of automobile, with its with can make after vehicle body is connected in the slide switch smooth and easy, and slide tenesmus in can effectively preventing.

The slide gliding groove comprises lower guideway, gliding groove lower plate, gliding groove upper cover plate and gliding groove front shroud in the automobile according to the invention; The gliding groove upper cover plate is welded on the end face of lower guideway; The cross section of lower guideway takes the shape of the letter U; The gliding groove upper cover plate extends to the lower guideway rear end from the lower guideway front end lower guideway is covered, and gliding groove lower plate top edge is welded on the soffit of gliding groove upper cover plate, is welded with reinforced company's fishplate bar on the gliding groove lower plate lateral surface.

Said reinforced company fishplate bar has two at least, and it is vertical with gliding groove lower plate lateral surface.

The gliding groove upper cover plate and the floor of this gliding groove are welded, and gliding groove front shroud and reinforced company's fishplate bar and longeron are welded, thereby realize being connected of gliding groove and vehicle body.

Slide gliding groove in the automobile according to the invention is because its lower guideway is to be connected with the gliding groove lower plate through the gliding groove upper cover plate; Thereby the lower guideway distortion of having avoided lower guideway and gliding groove lower plate directly to weld and having caused; And gliding groove welds through gliding groove upper cover plate and floor; Also can avoid being out of shape, thereby can guarantee the path accuracy of the spigot surface of lower guideway, make in the automobile slide switch smooth and easy owing to lower guideway directly welds the lower guideway that causes with the floor.Owing to be welded with reinforced company's fishplate bar in the gliding groove lower plate outside; Middle slide gliding groove not only welds through gliding groove front shroud and longeron; But also weld through this reinforced company's fishplate bar and longeron; Thereby strengthened the bonding strength of gliding groove and vehicle body, improved the bearing strength of gliding groove then, so the tenesmus of slide in can effectively preventing to slide in the automobile.

The specific embodiment

Like Fig. 1, Fig. 2 and shown in Figure 3; The slide gliding groove comprises lower guideway 3, gliding groove lower plate 1, gliding groove upper cover plate 4 and gliding groove front shroud 5 in this automobile; The cross section of lower guideway 3 takes the shape of the letter U; It faces the middle sliding door roller driving wheel bearing surface of gliding groove lower plate 1 downwards at the gliding groove split shed, and gliding groove upper cover plate 4 is welded on the end face of lower guideway 3, extends to lower guideway 3 rear ends from lower guideway 3 front ends lower guideway 3 is covered.The cross section of gliding groove lower plate 1 is step; The flange of its top edge partly is welded on the soffit of gliding groove upper cover plate 4; Gliding groove front shroud 5 is welded between gliding groove lower plate 1 and the gliding groove upper cover plate 4, with the front end closed-end of gliding groove, is welded with two reinforced company's fishplate bars 2 on gliding groove lower plate 1 lateral surface; Two reinforced company's fishplate bars 2 lay respectively at the middle part and the rear end of gliding groove lower plate 1, and are vertical with gliding groove lower plate 1 lateral surface.

Lower guideway 3 adopts rolling forming, and remaining parts then adopts drawing.In welding process, at first lower guideway 3 and gliding groove upper cover plate 4 are welded through the spot welding mode; The gliding groove upper cover plate 4 that second step will have been welded lower guideway 3 welds through the spot welding mode with the top edge flange part of gliding groove lower plate 1; The 3rd step was connected gliding groove front shroud 5 at the gliding groove front end with gliding groove lower plate 1, gliding groove upper cover plate 4 through the spot welding mode, with gliding groove front end closed-end; The 4th step was connected through the spot welding mode reinforced company's fishplate bar 3 with gliding groove lower plate 1, thereby formed gliding groove.
