[0002] As one of the important components in the car structure, the performance of the door has a great impact on the user's perception. The door hinge is a key component connecting the car body and the door. The door can be opened or closed by rotating around the hinge axis. The door hinge reinforcement plate is an important structure for installing the door hinge. Its structure and strength directly affect the stiffness of the door hinge installation point. If the stiffness of the door hinge installation point is insufficient, it will affect the door's over-opening strength. As the vehicle is used for a longer time, the plate at the door hinge installation point will deform, and the door will sag to a certain extent, which will directly affect the fit between the door and the body.

[0003] Most traditional hinge reinforcement plates are formed into an L-shape with the inner panel and have enhanced rigidity through features such as reinforcing ribs. However, this structure still has the problem of weak rigidity at the door installation point, and when the inner panel bends and deforms, the hinge reinforcement plate of the traditional structure is not conducive to preventing the bending and deformation of the door sheet metal.

[0042] Embodiment 1

[0043] The present embodiment relates to a vehicle door hinge installation point reinforcement structure, which can improve the rigidity of the vehicle door hinge installation point, thereby improving the overall installation quality of the vehicle door.

[0044] In terms of overall composition, Figures 1 to 3 As shown, the vehicle door hinge mounting point reinforcement structure of this embodiment includes a reinforcement bracket 2 arranged in the vehicle door. The reinforcement bracket 2 includes a first plate body 21 connected to the first side wall 11 of the vehicle door, and a second plate body 22 and a third plate body 23 connected to the first plate body 21. In addition, the vehicle door hinge mounting point is arranged on the first plate body 21, the second plate body 22 is connected to the second side wall 12 of the vehicle door, and the third plate body 23 is connected to the third side wall 13 of the vehicle door. Among them, the second side wall 12 is located on the side of the first side wall 11 close to the edge of the vehicle door, and the third side wall 13 is opposite to the second side wall 12 and is located on the other side of the first side wall 11.

[0045] At this time, the three plates in the reinforcing bracket 2 are respectively connected to the three side walls of the door, so that the three-point connection between the reinforcing bracket 2 and the door can be used to increase the connection rigidity between the reinforcing bracket 2 and the door, and the stability of the reinforcing bracket 2 on the door. At the same time, the connection between the second plate 22 and the third plate 23 and the door can improve the ability to cope with the door sagging and over-opening, thereby helping to improve the rigidity of the door hinge installation point and the overall installation quality of the door.

[0046] Based on the above overall introduction, specifically, as a preferred implementation, continue to refer to Figures 1 to 3In this embodiment, the reinforcement bracket 2 is specifically arranged on the door inner panel 1, and there are two reinforcement brackets 2 arranged at intervals along the height direction of the door inner panel 1. The two reinforcement brackets 2 are basically the same in structure, except that they are different in size and the shape of the weight reduction holes 233. Each reinforcement bracket 2 has a first plate body 21, and a second plate body 22 and a third plate body 23 connected to the first plate body 21. The door hinge mounting point is set on the first plate body 21.

[0047] The door inner panel 1 has a first side wall 11, a second side wall 12 and a third side wall 13 connected together. The second side wall 12 and the third side wall 13 are respectively located on both sides of the first side wall 11. The second side wall 12 and the first side wall 11 are connected in a smooth transition, and a corner Q is formed between the third side wall 13 and the first side wall 11, which is also connected in a smooth transition. The projections of the first side wall 11, the second side wall 12 and the third side wall 13 on the XY plane of the whole vehicle are roughly "S"-shaped or "Z"-shaped. Among them, the XY plane of the whole vehicle specifically refers to the plane formed by the X-axis and the Y-axis in the vehicle body coordinate system.

[0048] Still viewing Figures 1 to 3 The first plate 21 in the reinforcing bracket 2 is connected to the first side wall 11, the second plate 22 is connected to the second side wall 12, and the third plate 23 is connected to the third side wall 13. In addition, when it is implemented, each plate is usually connected to the corresponding side wall by spot welding.

Such a configuration can not only help reduce the weight of the reinforcing bracket 2, but also increase the reliability of the connection between the reinforcing bracket 2 and the second side wall 12.

[0050] Also as a preferred embodiment, in this embodiment, the third plate 23 is in the shape of a strip, and a triangular structure is formed between the first side wall 11, the third side wall 13 and the third plate 23. That is, the connection between the first plate 21 and the first side wall 11, the connection between the third plate 23 and the third side wall 13, the corner Q between the first side wall 11 and the third side wall 13, and the projection of one side of the third side wall 13 away from the corner Q on the third plate 23 form a roughly triangular structure. At this time, the high strength of the triangular structure can be used to increase the structural strength of the door itself, which can help prevent the torsional deformation of the door.

[0051] On the basis of the triangular structure formed above, in this embodiment, a connection flange 231 is also provided at one end of the third plate body 23 close to the third side wall 13, and the connection flange 231 is welded and connected to the third side wall 13. The setting of the connection flange 231 can facilitate the connection between the third plate body 23 and the third side wall 13, and is conducive to ensuring the reliability of the connection between the third plate body 23 and the third side wall 13.

[0052] Moreover, in this embodiment, a reinforcing flange 232 is also provided at at least one side edge of the third plate body 23. The provision of the reinforcing flange 232 can increase the structural strength of the third plate body 23 itself, and help to improve the overall rigidity of the reinforcing bracket 2. Preferably, in this embodiment, the reinforcing flanges 232 as above are provided at both side edges of the third plate body 23, so that the structural strength of the third plate body 23 itself can be better increased, and the overall rigidity of the reinforcing bracket 2 can be improved.

[0053] At the same time, in this embodiment, a weight-reducing hole 233 is also provided on the third plate 23, and a plurality of weight-reducing holes 233 are arranged at intervals along the length direction of the third plate 23. At this time, by providing the weight-reducing holes 233, it is helpful to strengthen the weight reduction of the bracket 2, and is conducive to the lightweight design of the entire door.

[0054] In this embodiment, the above-mentioned door hinge installation point specifically includes a screw connection structure provided on the first plate body 21, and the first side wall 11 and the first plate body 21 are provided with a connecting through hole 213 for connecting with the screw connection structure. The door hinge installation point adopts a screw connection structure provided on the first plate body 21, which has a simple structure, is easy to design and prepare, and can facilitate the installation operation of the door hinge.

[0055] Specifically, as a preferred embodiment, Figures 5 to 7 As shown, a mounting groove 210 is provided on the first plate 21, and the mounting groove 210 is formed by bending a portion of the first plate 21. The screw connection structure includes a mounting nut 26 provided in the mounting groove 210. The mounting nut 26 has a long strip-shaped body and a threaded hole provided on the body, which is, for example, Figure 7 The structure shown in the figure is an integrated structure, and it can also be a structure in which a long plate body and a nut are welded together. In specific implementation, the screw member sequentially passes through the connection hole 213 on the first side wall 11 and the connection hole 213 on the first plate body 21, and is screwed to the mounting nut 26, so that the reinforcing bracket 2 can be pre-fixed on the door inner panel 1.

[0056] Moreover, this embodiment forms a mounting groove 210 on the first plate body 21, and makes the threaded structure a mounting nut 26 set in the mounting groove 210, which is convenient for fine-tuning the position of the mounting nut 26 when the door hinge is installed, and helps to improve the convenience of door hinge installation.

[0057] In addition, as a preferred embodiment, in this embodiment, a retaining edge 211 is also provided on the first plate body 21, and the retaining edge 211 and the third plate body 23 respectively form shielding for the two side opening positions of the mounting groove 210. By shielding the two side opening positions of the mounting groove 210 formed by the retaining edge 211 and the third plate body 23, the stability of the mounting nut 26 in the mounting groove 210 can be increased, and the provision of the retaining edge 211 and the third plate body 23 can also play a certain guiding role for the mounting nut 26 in the mounting groove 210.

[0058] Also as a preferred embodiment, in this embodiment, a bending portion 212 is also provided on the first plate 21 at the notch of the mounting groove 210, and the bending portion 212 has a guiding inclined surface 2120 for guiding the mounting nut 26 to enter the mounting groove 210, and the bending portion 212 can clamp the entered mounting nut 26 in the mounting groove 210. The setting of the bending portion 212, on the one hand, can utilize the guiding inclined surface 2120 on the bending portion 212 to facilitate the installation of the mounting nut 26 into the mounting groove 210, and on the other hand, can also utilize the bending portion 212 to clamp the entered mounting nut 26, further improving the stability of the installation of the mounting nut 26.

[0059] The door hinge mounting point reinforcement structure of the present embodiment can increase the connection rigidity between the reinforcement bracket 2 and the door, as well as the stability of the reinforcement bracket 2 on the door, while also improving the ability to cope with door sagging and over-opening, thereby helping to improve the rigidity of the door hinge mounting point and the overall installation quality of the door, and having a very good use effect.
