It is easily understood that according to the technical solutions of the present application, a person skilled in the art can propose various alternative structural modes and implementation modes without changing the essential spirit of the present application. Therefore, the following detailed description and the accompanying drawings are only exemplary illustrations of the technical solutions of the present application, and should not be construed as being all of the present application or as defining or limiting the technical solutions of the present application.
The coordinate system established herein is explained below. The origin O of the coordinate system coincides with the center of mass of the vehicle and XOZ lies in the plane of bilateral symmetry of the vehicle. When the vehicle runs on a horizontal road surface, the X axis is parallel to the ground and points to the front, the Y axis points to the left side of a driver, and the Z axis points to the upper part through the center of mass.
An aluminum alloy quarter panel according to an embodiment of the present application is shown in conjunction with fig. 1-3. The aluminum alloy side wall outer plate is the side wall outer plate made of aluminum alloy. The rear door lock area 6 is shown by a dashed square in fig. 1, corresponding to the vicinity of the characteristic ridge 5 in the middle of the C-pillar area. For the aluminum alloy side wall outer plate, in the rear door lock area, the rear door parting seam of the aluminum alloy side wall outer plate extends discontinuously. "continuous" is understood herein from a mathematical perspective to mean that there is a discontinuity/line in the shape of the rear door seam of the aluminum alloy quarter panel as viewed from the side of the vehicle.
Referring to fig. 2, in the rear door lock area, the left boundary of the aluminum alloy side-frame outer panel is a door opening seam stop 1, and the right boundary is a rear door parting seam 2. With further reference to FIG. 3, in the back door lock area, the ratio of the lateral distance between the door opening stop 1 of the aluminum alloy side gusset outer panel and the back door parting 2 of the aluminum alloy side gusset outer panel to the longitudinal distance between the door opening stop 1 of the aluminum alloy side gusset outer panel and the back door parting 2 of the aluminum alloy side gusset outer panel is at least partially in the range of 0.6-0.7. That is, in the rear door lock region, the ratio of the lateral distance to the longitudinal distance between the door opening seam allowance 1 of the aluminum alloy side-frame outer panel and the rear door seam allowance 2 of the aluminum alloy side-frame outer panel may be entirely in the range of 0.6 to 0.7, or may be in the range of 0.6 to 0.7 at least in a certain cross section, for example, in the range of 0.6 to 0.7 in a cross section of a characteristic ridge line as indicated by a chain line in fig. 2.
The transverse distance between the door opening seam allowance of the aluminum alloy side-frame outer plate and the rear door seam allowance of the aluminum alloy side-frame outer plate is the distance along the transverse direction of the vehicle, namely the Y direction (also called Y direction depth Y); the longitudinal distance between the door opening seam allowance of the aluminum alloy side wall outer plate and the rear door seam allowance of the aluminum alloy side wall outer plate is a distance (also called as X-direction width X) along the longitudinal direction of the vehicle, namely the X direction.
Illustratively, the ratio of the transverse distance to the longitudinal distance between the door opening seam allowance of the aluminum alloy side-frame outer panel and the rear door seam allowance of the aluminum alloy side-frame outer panel is 0.6 or 0.7.
In the embodiment shown in fig. 3, in the rear door lock area of the aluminum alloy side wall outer plate, the transverse distance between the door opening stop 1 of the aluminum alloy side wall outer plate and the rear door parting joint 2 of the aluminum alloy side wall outer plate, namely the Y-direction depth Y =144mm; and the longitudinal distance between the door opening seam allowance of the aluminum alloy side wall outer plate and the rear vehicle door seam allowance of the aluminum alloy side wall outer plate, namely the X-direction width X =205mm. The ratio α = Y/X =144/205=0.7 of the Y-direction depth Y to the X-direction width X.
During the product development process, the inventor finds that the material flow of the aluminum alloy during the stamping process can be effectively controlled by properly adjusting the ratio of the transverse distance to the longitudinal distance between the door opening stop of the aluminum alloy side-frame outer plate and the rear door parting of the aluminum alloy side-frame outer plate.
In the aluminum alloy side wall outer plate according to the embodiment, the rear door parting line of the aluminum alloy side wall outer plate is arranged to extend discontinuously in the rear door lock area, so that a space is reserved for adjusting the proportion between the transverse distance and the longitudinal distance between the door opening seam allowance of the aluminum alloy side wall outer plate and the rear door parting line of the aluminum alloy side wall outer plate. The proportion of the transverse distance to the longitudinal distance between the door opening seam allowance of the aluminum alloy side wall outer plate and the rear door seam allowance of the aluminum alloy side wall outer plate is at least partially in the range of 0.6-0.7, so that the material flow of the aluminum alloy in the stamping process is effectively controlled and improved, the wrinkling and cracking of a finished product are reduced, particularly the cracking problem of the characteristic ridge line sharp corner of the C column of the side wall outer plate is reduced, the forming process of the aluminum alloy side wall outer plate is improved, and the forming defects are reduced.
Referring to fig. 3, in the rear door lock area, a first step 41 is provided on the aluminum alloy side-frame outer panel near the door opening stop of the aluminum alloy side-frame outer panel. Further, in the rear door lock area, a second step 42 is arranged on the aluminum alloy side wall outer plate and close to the rear door parting seam of the aluminum alloy side wall outer plate. Still further, in the rear door lock region, a third step 43 is provided between the first step and the second step on the aluminum alloy side body outer panel. Preferably, the length of the third step in the longitudinal direction is greater than the length of the second step and the first step in the longitudinal direction, so that during drawing, contact with the die is optimized to facilitate material flow.
The first step can be made as wide and as shallow as possible, i.e. as long as possible in the X direction and as far away from the center of the vehicle as possible, and as close as possible to the rear door parting line of the aluminum alloy side body outer panel. Optionally, the Y-direction position of the third step is adjusted so that the width of the side elevation at the lower part of the quadrangular window is consistent with the width of the side elevation at the parting position of the rear door. Still optionally, the second step is adjusted in the Y direction as close as possible to the center of the vehicle. Through the mode, the material flow of the aluminum alloy in the stamping process is further controlled and improved, the problem of stamping and cracking of characteristic ridge sharp corners near the C column of the side wall outer plate can be solved, and the wrinkling defect of the lower part of the four-corner window can be avoided.
Referring to fig. 4, the upper half portion 21 and the lower half portion 22 of the aluminum alloy side body outer panel at the rear door parting line are staggered. Specifically, the bottom 31 of the side quarter window 3 of the vehicle divides the rear door seam of the aluminum alloy side wall outer panel into an upper half 21 and a lower half 22, i.e., the upper half 21 and the lower half 22 of the rear door seam of the aluminum alloy side wall outer panel are bounded by the bottom 31 of the side quarter window 3 of the vehicle. Still more specifically, the lower half portion of the quarter joint of the aluminum alloy quarter outer panel is offset rearward relative to the upper half portion.
In this way, the material flow of the aluminum alloy during the stamping process is further controlled and improved, and furthermore the spatial arrangement of the vehicle body is improved.
The rear door parting seam of the aluminum alloy side wall outer plate is divided into an upper half part and a lower half part by the bottom of the side quarter window of the vehicle, and the lower half part of the rear door parting seam of the aluminum alloy side wall outer plate is staggered backwards relative to the upper half part. For example, the lower half portion of the side body outer panel at the rear door split is offset rearward by 30mm relative to the upper half portion.
In such a way, the position of the upper half part of the rear door parting position of the aluminum alloy side wall outer plate in the longitudinal direction of the vehicle body is kept unchanged, namely the position of the side four-corner window of the vehicle in the longitudinal direction of the vehicle body is kept unchanged, so that the condition that the light transmission boundary of the four-corner window moves towards the rear of the vehicle and the light transmission area of the side four-corner window is reduced can be avoided, and the riding experience of passengers in the vehicle is not influenced. In addition, wrinkling of the lower side quarter light can be avoided in this manner.
The present application also includes an automobile having the aluminum alloy quarter panel of any one or more of the embodiments described above, and the technical features and effects thereof are similar to those described above, and therefore will not be described herein again.
The technical scope of the present application is not limited to the contents in the above description, and those skilled in the art can make various changes and modifications to the above embodiments without departing from the technical spirit of the present application, and these changes and modifications should fall within the protective scope of the present application.
