Accompanying drawing 2 is the design attitude structural representation of leaking hole structure of the present invention on arrangements for automotive doors;
In figure, the implication of each Reference numeral is as follows:
1-car external door panel, 2-car internal hilar plate, 3-flange bound edge, the unsettled step of 4-, the unsettled step R of 5-angle, 6-liquid-leaking nozzle, 7-reinforced rib, 8-tops bar, and 9-gets out of a predicament or an embarrassing situation.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in detail, so that those skilled in the art can more clearly understand the solution of the present invention, but does not therefore limit the scope of the invention.
As shown in Figure 1, the liquid-leaking nozzle of arrangements for automotive doors of the present invention designs on car internal hilar plate, more specifically, near flange bound edge 3 positions below car external door panel 1 and car internal hilar plate 2 thresholds, on car internal hilar plate 2, design unsettled step 4, the size of described unsettled step 4 need to be according to the size of liquid-leaking nozzle, the decisions such as the shape of door, shoulder height need to decide according to plate drawing depth in door, as shown in Figure 1, described unsettled step is formed by the reinforced rib 7 on car internal hilar plate 2, and comprise and top bar 8 and get out of a predicament or an embarrassing situation 9, describedly top bar 8 and get out of a predicament or an embarrassing situation and 9 connected and composed by reinforced rib 7 one, and topping bar 8 and get out of a predicament or an embarrassing situation and between 9, form overhanging portion, and then unsettled step 4 entirety of the present invention have the planform of similar " mouth " font.By adopting reinforced rib, improve to a certain extent the intensity of car internal hilar plate, avoid the impact of liquid-leaking nozzle Punching Process on car internal hilar plate.Four jiaos of the unsettled step 4 of further described hollow are processed into arc structure, form unsettled step R corner structure 5, the Yuan arc Ban Jing≤3.0mm at described unsettled step R angle 5, and the height of described unsettled step is not less than 3 millimeters.
Liquid-leaking nozzle 6 of the present invention penetrates car internal hilar plate 2 and designs on unsettled step 4, concrete described liquid-leaking nozzle is through the 8 upwards extensions of topping bar of unsettled step, preferably there is square opening structure, be preferably dimensioned to be the square hole of 10.0mm × 10.0mm, and described liquid-leaking nozzle through unsettled step top bar 8 extend upwardly to top bar on another reinforced rib 7 of car internal hilar plate, the both sides up and down of liquid-leaking nozzle, all along the reinforced rib punching press of car internal hilar plate, make to drop to minimum to the deformation effect of car internal hilar plate in the course of processing of liquid-leaking nozzle like this.Described unsettled step size length and width direction requires than liquid-leaking nozzle Fang Xiang≤3.0mm, be the Ju Li≤3.0mm of two ends to the liquid-leaking nozzle two edges at middle part that top bar of unsettled step, Ju Li≤the 3.0mm of the liquid-leaking nozzle lower edge of getting out of a predicament or an embarrassing situation of unsettled step, liquid-leaking nozzle designed in the supermedial while of unsettled step like this, the wedge angle of liquid-leaking nozzle has been avoided the R angle of unsettled step, has avoided liquid-leaking nozzle wedge angle to form burr on unsettled step R angle.Liquid-leaking nozzle 6 of the present invention is across unsettled step, car internal hilar plate and 3 profile settings of car internal hilar plate reinforced rib, effectively eliminated the phenomenons such as wrinkling, the bounce-back in liquid-leaking nozzle punching course.
Further described unsettled step, magnitude setting and the position of liquid-leaking nozzle on car internal hilar plate, to guarantee that door-plate surface quality reaches after designing requirement and leakage not ponding and is as the criterion, the quantitative requirement of preferred liquid-leaking nozzle can not be less than 3, at most can not be more than 5, the setting position structure of multiple liquid-leaking nozzles as shown in Figure 2.Avoided the bound edge region of car external door panel and car internal hilar plate by the position that is arranged so that described liquid-leaking nozzle of unsettled step simultaneously, be that car external door plate limit after bound edge can not directly contact liquid-leaking nozzle, the setting of described liquid-leaking nozzle is not impacted the combination of door-plate inside and outside car, require in addition near the door-plate profile R angle of the inside and outside door-plate liquid-leaking nozzle of car in the same size, avoid R angle to change excessive, cause structural distortion.
The present invention by offering liquid-leaking nozzle and finally taking this kind of mode leakage on unsettled step, guarantee that through verification experimental verification car door assembly does not exist ponding, ensure that not offering of liquid-leaking nozzle impacts car door assembly liquid-leaking nozzle place surface quality, guaranteed that in inside and outside door-plate pressing process, door assembly surface quality is not affected by liquid-leaking nozzle simultaneously.Innovative characteristics and the technique effect of technical solution of the present invention at least comprise: (1) is by designing unsettled step at car internal hilar plate liquid-leaking nozzle place, then on unsettled step, offer liquid-leaking nozzle, avoided liquid-leaking nozzle directly with the laminating of car external door panel, thereby the burr that in car internal hilar plate punching course, liquid-leaking nozzle produces, be out of shape and car external door panel do not exerted an influence; (2) unsettled step can make up the undercapacity problem that car internal hilar plate causes because of design liquid-leaking nozzle to a certain extent; (3) liquid-leaking nozzle designs in unsettled step and requires step larger than liquid-leaking nozzle, and length and width aspect is greater than more than 3 millimeters, avoids liquid-leaking nozzle wedge angle on unsettled step R angle, causes liquid-leaking nozzle distortion.
Below be only that the preferred embodiment of the present invention is described; technical scheme of the present invention is not limited to this; the any known distortion that those skilled in the art do on the basis of major technique design of the present invention all belongs to the claimed technology category of the present invention, and the concrete protection domain of the present invention is as the criterion with the record of claims.
