DETAILED DESCRIPTION

[0025] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0026] like Figure 1 As shown, the door reinforcement plate of the disclosed embodiment includes a reinforcement plate body 1, which can be integrally formed by sheet metal stamping. A first mounting point and a second mounting point are provided on the reinforcement plate body 1, wherein the first mounting point is used to assemble the hinge, and the second mounting point is used to assemble the limiter. Both the first mounting point and the second mounting point can be hole-like structures so that fasteners such as bolts can pass through.

[0027] A plurality of ribs are also provided on the reinforcing plate body 1 . The plurality of ribs are arranged at intervals along the length direction of the reinforcing plate body 1 , and at least part of the ribs extend along the width direction of the reinforcing plate body 1 .

[0028] For example, Figure 1As shown, the length direction of the reinforcing plate body 1 can be the up-down direction, and the width direction of the reinforcing plate body 1 can be the left-right direction. Multiple ribs can be integrally formed on multiple reinforcing plate bodies 1, and three ribs can be provided, and the three ribs are respectively the first rib 5, the second rib 7 and the third rib 10. The first rib 5, the second rib 7 and the third rib 10 can extend along the left-right direction and be arranged at intervals in the up-down direction.

[0029] In some other embodiments, the number of ribs may be two, four, five, six, etc.

[0030] The door reinforcement plate of the disclosed embodiment is integrated with a first mounting point and a second mounting point, so as to respectively satisfy the installation and fixation requirements of the hinge and the limiter, avoiding the problem in the prior art that the hinge reinforcement plate and the limiter reinforcement plate are designed in separate pieces, which easily leads to mismatched stiffness of the door inner panel in the hinge load area, and meeting the requirements of the drooping stiffness and over-opening stiffness of the door.

[0031] Secondly, by arranging multiple ribs on the door reinforcement plate, the cross-sectional stiffness of the door reinforcement plate can be improved by the ribs, further meeting the requirements of the droop stiffness and over-opening stiffness performance of the door.

[0032] In addition, the integrated design of the reinforcement plate, on the one hand, facilitates the optimization of thinning the material thickness of the reinforcement plate body 1 and the arrangement of weight-reducing holes, which can reduce the overall weight and material while meeting the structural strength; on the other hand, it can reduce the number of overall parts, thereby simplifying the production process and improving the assembly production efficiency of the entire vehicle.

[0033] In some embodiments, the outer peripheral edge of the reinforcing plate body 1 is provided with a first overlapping edge 3 and a second overlapping edge 6 for connecting to the inner panel of the vehicle door. The first overlapping edge 3 and the second overlapping edge 6 both extend along the length direction of the reinforcing plate body 1 and are arranged relatively in the width direction of the reinforcing plate body 1.

[0034] For example, Figure 1 As shown, the first overlap edge 3 and the second overlap edge 6 can be integrally formed on the reinforcing plate body 1, wherein the first overlap edge 3 can be located on the left side of the reinforcing plate body 1, and the second overlap edge 6 can be located on the right side of the reinforcing plate body 1, and the first overlap edge 3 and the second overlap edge 6 can generally extend along the up and down directions.

[0035] During assembly, the first overlapping edge 3 and the second overlapping edge 6 can be overlapped and welded to the door inner panel respectively. This, on the one hand, facilitates the connection and fixation between the reinforcing plate body 1 and the interior of the door, and on the other hand, can enhance the local structural strength of the door inner panel, thereby meeting the need to withstand larger loads.

[0036] In some embodiments, the reinforcing plate body 1 is provided with a third lap edge 4 for connecting to the inner panel of the vehicle door. The third lap edge 4 is provided at the end of the second lap edge 6 and extends toward the outside of the reinforcing plate body 1, and the extension direction of the third lap edge 4 is arranged to intersect with both the width direction and the length direction.

[0037] For example, Figure 1 As shown, the third overlapping edge 4 can also be integrally formed on the reinforcing plate body 1. The third overlapping edge 4 can be specifically arranged at the upper right corner of the reinforcing plate body 1, and the third overlapping edge 4 can generally extend from the lower left to the upper right.

[0038] During assembly, the third overlapping edge 4 can be connected to the door inner panel through a welding point. The third overlapping edge 4 can strengthen the effect of the weak area of ​​the opening and closing durability of the door inner panel, so that the opening and closing durability of the door can meet the target value.

[0039] In some embodiments, a flange 9 is provided at the outer peripheral edge of the reinforcing plate body 1 , the third overlapping edge 4 is located at one end of the reinforcing plate body 1 in the length direction, and the flange 9 is located at the other end of the reinforcing plate body 1 in the length direction.

[0040] For example, Figure 1 As shown, the flange 9 can be integrally formed on the bottom side of the reinforcing plate body 1, and the flange 9 generally extends along the bottom edge of the reinforcing plate body 1. The setting of the flange 9 can further enhance the local structural strength of the reinforcing plate body 1 on the one hand, and improve the problem of stress concentration on the other hand.

[0041] In some embodiments, the door reinforcement plate includes a mounting plate 2 , the mounting plate 2 is fixed to the reinforcement plate body 1 , and the first mounting point includes a first mounting hole 11 , and the first mounting hole 11 passes through the mounting plate 2 and the reinforcement plate body 1 .

[0042] For example, Figure 1 As shown, the mounting plate 2 can be fixed to the rear side of the reinforcing plate body 1 by welding, the first mounting hole 11 can be a round hole and can be only provided with one, and the first mounting hole 11 can generally penetrate the mounting plate 2 and the reinforcing plate body 1 along the front-to-back direction. During assembly, the mounting plate 2 can be pre-connected with the door reinforcing plate at the supplier, and the bolts can pass through the reinforcing plate body 1 and the mounting plate 2 through the first mounting hole 11, thereby facilitating the installation and fixation of the hinge.

[0043] In some embodiments, an installation area 8 is provided on the reinforcement plate body 1, which protrudes toward one side of the reinforcement plate body 1 and forms a first cavity on the other side of the reinforcement plate body 1 for increasing the cavity cross-section between the reinforcement plate body 1 and the inner panel of the vehicle door, and the second installation point is provided in the installation area 8.

[0044] For example, Figure 1As shown, the installation area 8 can be arranged in the lower area of ​​the reinforcing plate body 1, and the installation area 8 can be formed by stamping. A punch or the like can be punched from the front side to the rear side of the reinforcing plate body 1, thereby making the installation area 8 bulge toward the rear side as a whole and form a concave cavity on the front side, which is the first cavity.

[0045] When the reinforcement plate body 1 is installed on the door inner panel, the first cavity can be located between the door inner panel and the mounting area 8. Since the mounting area 8 protrudes rearward, the spatial distance between the door inner panel and the mounting area 8 can be increased, thereby increasing the cavity cross-section, thereby improving the droop stiffness and over-opening stiffness performance of the door.

[0046] In some embodiments, the third rib 10 and flange 9 may be disposed on the peripheral side of the mounting area 8 and spaced along the circumference of the mounting area 8. The third rib 10 may be located on the left side of the mounting area 8, and the flange 9 may be located on the lower side of the mounting area 8.

[0047] In some embodiments, the second mounting point includes a plurality of second mounting holes 12 and a through hole 13, the through hole 13 penetrates the reinforcing plate body 1 along the thickness direction of the reinforcing plate body 1, and the through hole 13 is used for allowing at least part of the limiter to pass through, and the plurality of second mounting holes 12 are arranged on the peripheral side of the through hole 13 and are arranged at intervals along the circumference of the through hole 13.

[0048] For example, Figure 2 As shown, the through hole 13 can be generally a square hole, and two second mounting holes 12 can be provided, and both second mounting holes 12 can be round holes, one of the second mounting holes 12 can be provided on the upper side of the through hole 13, and the other second mounting hole 12 can be provided on the lower side of the through hole 13. During assembly, the second mounting hole 12 can be provided for fasteners such as bolts to pass through, thereby facilitating the connection and fixation of the stopper to the reinforcing plate body 1. The main body of the stopper can pass through the through hole 13 and be connected to the vehicle body, thereby meeting the use requirements of the stopper assembly.

[0049] In some embodiments, a plurality of convex strips are provided on the reinforcing plate body 1, each of which protrudes toward one side of the reinforcing plate body 1 and forms a second cavity on the other side of the reinforcing plate body 1 for increasing the cavity cross-section between the reinforcing plate body 1 and the inner door panel, and the convex strips form ribs.

[0050] For example, Figure 1 As shown, three convex strips can be provided, and each convex strip can be formed by stamping. During processing, a punch can be located at the front side of the reinforcing plate body 1, and the punch can punch the reinforcing plate body 1 backward, thereby, a part of the reinforcing plate body 1 can bulge backward and form a convex strip, and a concave cavity is formed on the front side of each convex strip, and the concave cavity is the second cavity.

[0051] When the reinforcing plate body 1 is fixed on the door inner panel, the second cavity can be located between the door inner panel and the convex strip, thereby increasing the distance between the reinforcing plate body 1 and the door inner panel, and also improving the droop stiffness and over-opening stiffness performance of the door.

[0052] In some embodiments, the reinforcing plate body 1 is provided with a plurality of process holes, which are used for positioning or allowing fasteners to pass through the reinforcing plate body 1.

[0053] The first process hole 14 and the second process hole 15 can be arranged on the top side of the reinforcing plate body 1 and can be arranged at intervals in the left and right directions. The first process hole 14 and the second process hole 15 can be passed through by fasteners such as bolts, thereby facilitating assembly and improving convenience. The third process hole 16 can be arranged between the first process hole 14 and the second process hole 15. The third process hole 16 can cooperate with a positioning pin, etc., so as to play a role in positioning the reinforcing plate body 1 during processing and assembly.

[0054] The fourth process hole 19 can be arranged on the right side of the installation area 8, and the fourth process hole 19 can also be used for fasteners such as bolts to pass through, thereby improving the convenience of assembly.

[0055] In some embodiments, a plurality of weight-reducing holes are provided on the reinforcing plate body 1, the reinforcing plate body 1 has a stress concentration area and a stress non-concentration area, the plurality of weight-reducing holes are provided in the stress non-concentration area, and the plurality of ribs are provided in the stress concentration area.
