[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0034] like Figures 1-9As shown, this utility model provides a car door hinge mounting structure for mounting car door hinges. The car door can be the left or right side door of the passenger compartment or a hinged rear door. In this embodiment, the car door is a hinged rear door. The car door hinge mounting structure includes an inner door panel 1, a reinforcing member 2, and a bracket 3. The inner door panel 1 includes a hinge mounting plate 11 for mounting the hinge and a window frame rib 12 for reinforcing the structural strength of the window frame. The two are spaced apart along the width direction of the inner door panel 1 and protrude in the same direction relative to the inner door panel 1, thereby forming a mounting groove 13 between the hinge mounting plate 11 and the window frame rib 12. The mounting groove 13 has a U-shaped structure, and its two side walls correspond to the hinge mounting plate 11 and the window frame rib 12, respectively. The reinforcing member 2 is set as a U-shaped structure, and the reinforcing member 2 cooperates with the groove wall of the mounting groove 13 and is welded to the inner door panel 1. The bracket 3 is set in the mounting groove 13, specifically in the U-shaped reinforcing member 2, and fits against the reinforcing member 2. The bracket 3 extends along the width of the inner door panel 1. One end of the bracket 3 is welded to the reinforcing member 2 and the hinge mounting plate 11 using a three-layer spot welding method. The other end of the bracket 3 is welded to the reinforcing member 2 and the window frame rib 12 using a three-layer spot welding method. By welding the reinforcing member 2 and the bracket 3 onto the inner door panel 1, the rigidity and structural strength of the hinge mounting plate 11 are improved. Simultaneously, the hinge mounting plate 11 and the window frame rib 12 of the inner door panel 1 form mounting grooves 13. The reinforcing member 2 and the bracket 3 are both placed within the mounting grooves 13, and both ends of the bracket 3 support the hinge mounting plate 11 and the window frame rib 12 respectively. Structurally, this further improves the rigidity and structural strength of the hinge mounting plate 11, thereby effectively suppressing deformation.
[0035] Furthermore, the reinforcing member 2 includes a first connecting portion 21, a second connecting portion 22, a third connecting portion 23, and a fourth connecting portion 24. These four portions are integrally formed. The first connecting portion 21 is attached to and welded to the hinge mounting plate 11; the second connecting portion 22 is attached to and welded to the bottom wall of the mounting groove 13; the third connecting portion 23 is attached to and welded to the window frame rib 12; and the fourth connecting portion 24 is welded to the window frame stop of the inner door panel 1. By welding the fourth connecting portion 24 to the window frame stop of the inner door panel 1, the structural strength of the reinforcing member 2 is further increased, enhancing its support effect on the hinge mounting plate 11. The reinforcing member 2 is only installed at the location on the hinge mounting plate 11 where the door hinge is installed, eliminating the need to completely cover the hinge mounting plate 11, thus reducing material usage and the number of weld points, and contributing to weight reduction.
[0036] Optionally, such as Figure 8As shown, a first weight-reducing hole 221 is provided on the second connecting portion 22. The first weight-reducing hole 221 is a round hole or a square hole, which reduces the weight of the reinforcing member 2 while ensuring structural strength. A second weight-reducing hole 231 is provided on the third connecting portion 23. The second weight-reducing hole 231 is a round hole or a square hole, which further reduces the weight of the reinforcing member 2 while ensuring structural strength. A weight-reducing notch 241 is provided on the fourth connecting portion 24. The weight-reducing notch 241 is located on the side of the fourth connecting portion 24 away from the third connecting portion 23, which further reduces the weight of the reinforcing member 2 while ensuring structural strength, ultimately achieving a high degree of lightweighting.
[0037] Furthermore, such as Figures 1-6 and refer to Figure 9 As shown, the bracket 3 includes a hinge fixing plate 31 and two support plates 32 located at both ends of the hinge fixing plate 31. The hinge mounting plate 11 is a flat plate and is used for welding connection to the hinge mounting plate 11. The support plates 32 extend along the width direction of the inner door panel 1. One end of the support plate 32 is integrally formed and connected to the hinge fixing plate 31, and the other end of the support plate 32 is welded to the third connecting part 23 and the window frame protrusion 12. By setting the support plates 32, the hinge mounting plate 11 is supported along the width direction of the inner door panel 1, effectively preventing the hinge mounting plate 11 from deforming along the width direction of the inner door panel 1.
[0038] Specifically, the end of the support plate 32 away from the hinge mounting plate 11 is folded outward to form a first welding ear 33. The first welding ear 33 is attached to the third connecting part 23 and welded to the third connecting part 23 and the window frame rib 12. The specific welding method is three-layer spot welding. By setting the first welding ear 33, the welding operation is facilitated, and welding can be performed by three-layer spot welding, resulting in higher weld quality and a simpler welding process. The bracket 3 is folded outward on the side facing the second connecting part 22 to form a second welding ear 34. The second welding ear 34 is attached to the second connecting part 22 and welded to the second connecting part 22 and the bottom wall of the mounting groove 13. The specific welding method is three-layer spot welding. By setting the second welding ear 34, the welding operation is facilitated, and welding can be performed by three-layer spot welding, resulting in higher weld quality and a simpler welding process. In addition, the setting of the second welding ear 34 increases the connection points between the bracket 3 and the reinforcing member 2 and increases the direction of structural support, thereby significantly improving the structural strength and rigidity. This enables the hinge mounting plate 11 to resist deformation impacts from all directions.
[0039] Alternatively, please refer to Figure 9 As shown, a reinforcing rib 321 protrudes from the support plate 32 and extends along the length of the support plate 32. The reinforcing rib 321 further increases the structural strength of the bracket 3 and ensures the support effect of the bracket 3 on the hinge mounting plate 11.
[0040] Specifically, please refer to Figures 1-6 As shown, and in combination Figure 8 The first connecting part 21 is provided with a first welding area 212. The surface of the first welding area 212 is set as a plane and is attached to the hinge mounting plate 11. The weld point between the first connecting part 21 and the hinge mounting plate 11 is located within the first welding area 212 to ensure the weld penetration and avoid incomplete welds. Please refer to... Figure 8 and Figure 9 The second connecting part 22 has two second welding areas 222 spaced apart. The surface of the second welding area 222 is flat and adheres to the bottom wall of the mounting groove 13. The second welding lug 34 adheres to the second welding area 222. Thus, the second welding lug 34, the second connecting part 22, and the bottom wall of the mounting groove 13 are connected by three layers of spot welding, ensuring the penetration depth of the weld and avoiding incomplete welds. The third connecting part 23 has two third welding areas 232 spaced apart. The surface of the third welding area 232 is flat and adheres to the window frame rib 12. The first welding lug 33 adheres to the third welding area 232. Thus, the first welding lug 33, the third connecting part 23, and the window frame rib 12 are connected by three layers of spot welding, ensuring the penetration depth and avoiding incomplete welds. Please refer to... Figures 7-9 The hinge mounting plate 11 has multiple first mounting holes 111, the first connecting part 21 has multiple second mounting holes 211 corresponding to the multiple first mounting holes 111, and the hinge fixing plate 31 has multiple third mounting holes 311 corresponding to the multiple second mounting holes 211. That is, the multiple first mounting holes 111, multiple second mounting holes 211, and multiple third mounting holes 311 correspond one-to-one. Fasteners pass through the first mounting holes 111, the second mounting holes 211, and the third mounting holes 311 in sequence to install the door hinge on the hinge mounting plate 11. Specifically, the third mounting hole 311 can be set as a threaded hole, or a corresponding projection weld nut can be set on the third mounting hole 311.
[0041] This utility model provides a hinged tailgate, including an outer door panel, a door hinge, and a door hinge mounting structure as described in this embodiment. The outer door panel is welded to the inner door panel 1, and the door hinge is mounted on the door hinge mounting structure. By setting the door hinge mounting structure of this embodiment, the rigidity and structural strength at the hinge mounting position are increased, significantly reducing the probability of deformation and avoiding problems such as the door not closing properly or even failing to close.
[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
