Referring to fig. 1, the door inner panel 100 includes a door panel body 10 and at least one flange 20.

The door panel body 10 is formed by processing a hard plate material, and an inner surface 11 and an outer surface 12 thereof are parallel, the door panel body 10 forms a main body portion of a door inner panel 100, and the door outer panel is mounted on the outer side of the door panel body 10 when the door inner panel 100 is assembled with the door outer panel. The edge portion of the door panel body 10 may be bent toward the inner side thereof, and the door panel body 10 may be provided with a plurality of mounting holes for mounting screws or rivets and a plurality of avoiding holes for avoiding other structural members.

The door panel body 10 has a visible area and an invisible area, and it is understood that the visible area is a portion that is not shielded from view by the door outer panel after the assembly of the door inner panel 100 and the door outer panel, and the invisible area is a portion that is not shielded from view by the door outer panel after the assembly of the door inner panel 100 and the door outer panel.

The door panel body 10 is provided with a through hole 101 in the invisible area, and the through hole 101 is away from the mounting hole and the away hole. The shape of the through hole 101 may be circular, elliptical, polygonal, or irregular, and the like, and is not limited thereto.

The flange 20 is connected to the wall of the through hole 101 and protrudes from the inner surface 11 of the door panel body 10, and the flange 20 extends from the wall of the through hole 101 toward a direction away from the door panel body 10. The flange 20 has opposite ends, one end of which is connected to the wall of the through hole 101 and the other end of which is a free end remote from the door panel body 10, so that the extending direction of the flange 20 is a direction from the wall of the through hole 101 toward the free end of the flange 20, which forms the edge of the flange 20.

Referring to fig. 2, the flange 20 has at least an everting segment 21, and an extending end of the everting segment 21 is bent in a direction away from a central axis of the through hole 101. It will be appreciated that the distance between the end of the eversion segment 21 remote from the door panel body 10 and the central axis of the through hole 101 is greater than the distance between the end of the eversion segment 21 near the door panel body 10 and the central axis of the through hole 101, and the bending angle of the eversion segment 21 relative to the door panel body 10 is greater than 90 °, i.e. the eversion segment 21 is formed by reverse bending, and the included angle a between the eversion segment 21 and the inner surface 11 of the door panel body 10 is less than 90 °. Wherein the projection of the eversion segment 21 onto the door panel body 10 is located in the invisible area.

Referring to fig. 3, in the door inner panel 100, by providing the flange 20 and providing the flange 20 with the reverse bent outward turned section 21, when a plurality of door inner panels 100 are stacked front and back, the flange 20 of the door inner panel 100 on the outer side can be abutted against another door inner panel 100 on the inner side thereof through the outward turned section 21, so that the flange 20 can support the door panel body 10, so that the door panel bodies 10 of two adjacent door inner panels 100 are spaced apart, and the problem that the flange 20 stretches into the through holes 101 of the other door inner panels 100 when the door inner panels 100 are stacked front and back with the other door inner panels 100 is avoided. Since the abutting position of the flange 20 of the outer door inner panel 100 on the inner door inner panel 100 is located near the through hole 101 and the projection of the eversion piece 21 toward the door panel body 10 is located in the invisible area, the abutting position of the flange 20 on the other door inner panel 100 is also located in the invisible area on the outer side of the other door panel body 10, and even if the two door inner panels 100 rub against each other due to shaking during the transportation of the material rack, the flange 20 of the door panel body 10 scratches a scratch on the other door inner panel 10, which is also located in the invisible area on the outer side of the other door panel body 10, after the door inner panel 100 and the door outer panel are assembled, the scratch is invisible, and the appearance of the assembled door panel is ensured to be defect-free. Meanwhile, the flanging 20 can be formed by forming a low hole on the door plate body 10 and bending the edge part of the wall of the bottom hole, the process can be formed in the single-piece processing process of the door inner plate 100, the full-automatic material taking is not affected, other structural parts are not required to be newly added, and the processing process is convenient and efficient and has low cost.

In some embodiments, referring to fig. 1, the flange 20 is circumferentially disposed along the wall of the through hole 101, and the flange 20 is formed in a ring shape. Thus, the support range of the bead 20 is increased, and the support effect of the bead 20 on the door panel body 10 of the other abutted door inner panel 100 is improved.

Wherein, the stacking distance between the door panel bodies 10 of the adjacent two door inner panels 100 is equal to the distance H (as shown in fig. 2) between the edge of the free end of the flange 20 and the inner surface 11 of the door panel body 10, and changing the value of the distance H can change the stacking distance between the door panel bodies 10 of the adjacent two door inner panels 100. In the vehicle model development process, the distance H may be adjusted according to the requirement for the stacking distance between the door panel bodies 10 of the adjacent two door inner panels 100. The distance H is at least determined by the extension of the flange 20 and the angle of bending of the everting segment 21. The extended length refers to the length of the flange 20 in the extending direction thereof.

Optionally, the everting segment 21 is annular and has an inner diameter that diverges in a direction away from the door panel body 10, i.e., in an extending direction of the flange 20. In this way, the flange 20 can ensure that the eversion piece 21 abuts against the inner side other door inner panel 100, so that the eversion piece 21 is prevented from sliding into the through hole 101 of the inner side other door inner panel 100 and cannot support the door panel body 10 due to shaking of the door inner panel 100.

In the embodiment shown in fig. 2, the section of the everting segment 21 is plane, and when the everting segment 21 with the plane section is subjected to the pressure in the direction of the central axis of the through hole 101, the everting segment 21 with the plane section is less prone to deformation than the everting segment 21 with the curved section.

Alternatively, referring to fig. 2, the included angle a between the eversion segment 21 and the inner surface 11 of the door panel body 10 is 60 °. Under the angle, the eversion section 21 can keep a large enough distance from the adjacent door plate body 10, the structure is stable, and the joint of the turnup 20 and the door plate body 10 is not easy to deform under the action of external force.

In some embodiments, the extending lengths of the flanges 20 are the same at each position, so as to ensure that the edges of the free ends of the flanges 20 of the outer door inner panel 100 are supported on the door panel body 10 of the inner other door inner panel 100 when a plurality of door panels are stacked on the material frame front and back, so that the flanges 20 can be uniformly stressed around the through holes 101, deformation of the flanges 20 due to excessive local stress is avoided, and deep scratches on the edges of the free ends of the flanges 20 due to excessive local pressure are avoided at the outer side of the inner other door inner panel 100.

In other embodiments, the length of the flange 20 may be different, that is, the height of the flange 20 protruding from the inner side of the door panel body 10 is greater than the height of the other portions protruding from the inner side of the door panel body 10, so that only the higher portion of the flange 20 abuts against the outer side other door inner panel 100, and only the portion may scratch the outer side other door inner panel 100, so as to reduce the area of the scratched area. The flange 20 may be connected to only a portion of the hole wall of the through hole 101, for example, the flange 20 is in a strip shape or a ring shape with a notch, so as to avoid other structural members, which is not limited herein.

In some embodiments, the junction of the flange 20 and the wall of the through hole 101 is rounded so that the junction of the flange 20 and the door panel body 10 is smoothly transitioned. Thus, the flange 20 is formed by bending the plate material forming the door panel body 10, so that the rapid processing is facilitated.

Optionally, referring to fig. 2, the flange 20 further has a connecting section 22, the connecting section 22 is connected to the hole wall of the through hole 101 and protrudes out of the inner surface 11 of the door panel body 10, the inner diameter of the connecting section 22 is reduced along the direction away from the door panel body 10, one end of the everting section 21, which is close to the door panel body 10, is connected to one end of the connecting section 22, which is away from the door panel body 10, the everting section 21 is connected to the door panel body 10 through the connecting section 22, and the inner diameter of the everting section is gradually enlarged along the direction away from the door panel body 10, so that the inner diameter of the flange 20 is gradually reduced and then gradually enlarged along the direction away from the door panel body 10, and the connecting section 22 can make the angle transition between the everting section 21 and the door panel body 10 more gentle, thereby avoiding the door panel body 10 from being broken when the flange 20 is formed by punching.

It should be noted that, the projection of the turned-out section 21 toward the door panel body 10 may be partially located on the door panel body 10 and another portion located on the connecting section 22, so that when the plurality of door inner panels 100 are stacked on the rack, the turned-out section 21 of the door inner panel 100 may abut against the outer surface 12 of the door panel body 10 of the other door inner panel 100. The projection of the eversion segment 21 toward the door panel body 10 may also be located entirely on the connecting segment 22, so that when a plurality of door inner panels 100 are stacked on the material rack, the eversion segment 21 of one door inner panel 100 can abut against the connecting segment 22 of the flange 20 of the other door inner panel 100 on the inner side, so that the function of spacing the door panel body 10 can also be realized. In practical application, the selection can be performed according to practical needs.

In other embodiments, the turning-over may have only the everting segment 21, where one end of the everting segment 21 is directly connected to the wall of the through hole 101, and the connection between the everting segment 21 and the wall of the through hole 101 is rounded. In this way, the projection of the eversion segment 21 toward the door panel body 10 may be located entirely on the door panel body 10, and the eversion segment 21 of one door inner panel 100 may abut against the outer surface 12 of the door panel body 10 of the other door inner panel 100 inside when the plurality of door inner panels 100 are stacked on the rack.

In some embodiments, the flange 20 is a stamped flange 20. During processing, the door panel body 10 can be perforated, then the edge part of the hole wall is bent to the inner side of the door panel body 10 by punching to form a hole flanging, and then the hole opening part of the hole flanging is reamed by a reaming device to form a reverse bent eversion section 21, so that the flanging 20 is formed by processing.

Optionally, referring to fig. 1, the through hole 101 is a circular hole, so as to facilitate stamping, and the corresponding hole flanging is also circular, and the structural stability of the circular flanging 20 is higher, so that the circular flanging is not easy to be deformed by compression. Wherein the flange 20 may be arranged centrally and symmetrically.

At this time, since the flange 20 is formed by punching the hole of the door panel body 10 and then flaring, the extending length of the flange 20 is smaller than the radius of the through hole 101, that is, the processing efficiency is improved and the processing cost is low.

In other embodiments, the flange 20 may also be formed by pressing the edge of the opening on the door panel body 10 by other devices against or clamping the edge by displacement, or by welding other structural members to the wall of the through hole 101, which is not limited herein.

In some embodiments, referring to fig. 1, the door panel body 10 is provided with three through holes 101, the three through holes 101 are not on the same straight line, and a flange 20 is connected to the wall of each through hole 101. Thus, the three flanges 20 which are not on the same straight line can stably support the door panel body 10, and the door panel body 10 is prevented from being knocked or worn due to back and forth shaking when a plurality of door inner panels 100 are stacked back and forth.

In other embodiments, the number of the through holes 101 may be less than three or more than three, which is not limited herein, and the number and the position may be selected according to the actual requirement in the production process.
