Abstract
The invention discloses a lower sliding groove of a middle sliding door of an automobile. The lower sliding groove comprises a guide rail of which the cross section is in an inverted U shape, an upper cover plate and a lower plate. The right side of the guide rail is longer than the left side of the guide rail. The upper cover plate is welded to the front end on the guide rail and in a trapezoid shape and the lower plate is welded to the lower portion of the right of the guide rail. The cross section of the lower plate is in a trapezoid shape and the part, corresponding to a boarding tread, of the front end of the guide rail is provided with a guide rail reinforcing part. The cross section of the guide rail reinforcing part is shaped like the Arabic number seven. The upper surface of the guide rail reinforcing part is welded to the lower surface of the upper cover plate. The right side of the guide rail reinforcing part is welded to the outer side face of the left side of the front end of the guide rail. The lower sliding groove of the middle sliding door of the automobile has high strength and the problems that the middle sliding door falls off, opening and closing of the middle sliding door are not smooth and abnormal sound exists are solved.
Description
Technical field
The present invention relates to automobile body components, be specifically related to a kind of downwards sliding groove of vehicle middle slide door.
Background technology
The middle slide switch swimmingly of automobile (such as commercial vehicle, micro-car), directly has influence on the quality of this car quality, and middle slide gliding groove is slide switch one of critical component smoothly in impact.
CN 102505908 A disclose a kind of downwards sliding groove of vehicle middle slide door, comprise lower guideway, gliding groove lower plate, gliding groove upper cover plate and gliding groove front shroud, gliding groove upper cover plate is welded on the end face of lower guideway, the cross-sectional plane of lower guideway takes the shape of the letter U, gliding groove upper cover plate extends to lower guideway rear end from lower guideway front end lower guideway is covered, gliding groove lower plate upper limb is welded on the lower surface of gliding groove upper cover plate, on gliding groove lower plate lateral surface, is welded with reinforced company's fishplate bar.There are the following problems for this gliding groove structure: (1) gliding groove upper cover plate has covered whole lower guideway end face, lower guideway in the time welding with gliding groove upper cover plate easily because welding the long distortion that produces; (2) gliding groove upper cover plate is longer, and the material needing is more, causes middle slide gliding groove entirety heavier, and cost is higher; (3) the anterior position (being threshold vehicle or floor place) of directly trampling corresponding to passenger loading of lower guideway, belongs to the power position that is frequently hit, its intensity a little less than, be repeatedly subject to be out of shape after foot-operated impulsive force, easily cause switch gate not smooth; (4) in middle slide switching process, the anterior side of lower guideway is also frequently stressed, and it lacks support, often have out shelves and become large, lower guideway local deformation phenomenon occurs, and its spigot surface path accuracy is poor, easily cause middle slide pulley to rock generation abnormal sound, in even occurring, fall phenomenon under slide, in switch, when slide, have some setbacks, have abnormal sound.
Summary of the invention
The object of this invention is to provide a kind of downwards sliding groove of vehicle middle slide door, to improve its intensity, in avoiding occurring, fall under slide, switch has some setbacks, abnormal sound problem.
Downwards sliding groove of vehicle middle slide door of the present invention, comprise section be down " U " shape and the right guide rail long compared with the left side, with leading section welding above guide rail and be trapezoidal upper cover plate, lower plate with bottom, the right welding of guide rail, described lower plate section is notch cuttype, the position that the leading section of described guide rail is trampled corresponding to passenger loading is provided with guide rail reinforcement, the section of this guide rail reinforcement is " 7 " font, the lower surface welding of its upper surface and upper cover plate, the lateral surface welding on its right flank and the guide rail leading section left side.
Further, in order to guarantee guide rail intensity, avoid distortion, above-mentioned downwards sliding groove of vehicle middle slide door also comprises that two sections are the side attaching parts of " leather boots shape ", and a side attaching parts is located at the middle part of described guide rail, and another side attaching parts is located at the rearward end of described guide rail; The left surface bottom of described side attaching parts and the welding of the lower right side of lower plate, the medial surface welding of the right flank on the top of described lower plate and bottom, guide rail the right, the lateral surface welding of the left surface top of described side attaching parts and bottom, guide rail the right; On the top of described lower plate, the connecting portion on the left surface top of guide rail bottom, the right and side attaching parts forms three layers of welding structure.
Further, above-mentioned downwards sliding groove of vehicle middle slide door also comprises shrouding, the upper limb of shrouding and the welding of the front of upper cover plate, and the lower edge of shrouding and the welding of the front of lower plate, form the gliding groove die cavity sealing.
The present invention has following effect:
(1) upper cover plate is welded on front end above guide rail, it does not cover above whole guide rail, reduce the number of welds of upper cover plate and guide rail, improve the distortion that guide rail produces because of welding, improved the stock utilization of upper cover plate simultaneously, alleviate the weight of middle slide gliding groove, for lightweight is contributed, also saved cost.
(2) increase the guide rail reinforcement that a section is " 7 " font, upper cover plate and guide rail front portion have been supported, effectively promoted rigidity, the intensity of guide rail, effectively avoided time sliding Free to be subject to for many times the switch gate that distortion causes after foot-operated impulsive force not smooth; Effectively guarantee the path accuracy of spigot surface, can avoid in slide process, because of the numerous stressed local deformation that occurs of guide rail front side frequency, avoiding the scroll wheel of middle slide to rock generation abnormal sound in switch, in avoiding occurring, fallen under slide, have some setbacks, abnormal sound problem.
(3) the medial surface welding of the right flank on the top of lower plate and bottom, guide rail the right, the lateral surface welding of the left surface top of side attaching parts and bottom, guide rail the right, on the top of lower plate, the connecting portion on the left surface top of guide rail bottom, the right and side attaching parts forms three layers of welding structure, this welded structure has guaranteed guide rail intensity, avoids distortion.
(4) realize and being connected of car body component by side attaching parts, because side attaching parts had not only welded with rail welding but also with lower plate, its can more easily realize in slide gliding groove be connected with the firm of vehicle body.
