The vehicle door hinge reinforcement structure comprises a reinforcement seat 1 and a mounting plate 2. The mounting plate 2 is connected to the outer side of the vehicle body sheet metal 7. The mounting plate 2 is provided with a first axle seat and a second axle seat for mounting the vehicle door hinge 8. The reinforcement seat 1 is connected to the inner side of the vehicle body sheet metal 7 and corresponds to the inner and outer sides of the mounting plate 2.

[0029] Compared with the prior art, the door hinge reinforcement structure provided in the present embodiment realizes structural reinforcement of the installation position of the door hinge 8 by correspondingly arranging a reinforcement seat 1 and a mounting plate 2 on the inner and outer sides of the vehicle body sheet metal 7, and reliably installs the door hinge 8 with the help of the first axle seat and the second axle seat, thereby effectively improving the structural stiffness of the installation position, providing a solid installation point for the door hinge 8, and meeting the dynamic simulation requirements of the door hinge 8 and the vehicle door system.

[0030] In this embodiment, the reinforcement seat 1 is installed on the inner side of the body sheet metal 7, and forms a corresponding relationship with the mounting plate 2 on the inner and outer sides of the body sheet metal 7, thereby enhancing the structural rigidity of the installation position of the door hinge 8, providing a reliable installation basis for the installation of the door hinge 8, avoiding structural deformation caused by excessive force on the body sheet metal 7, ensuring the structural rigidity of the installation position of the door hinge 8, and facilitating meeting the precision requirements of the door installation.

[0031] The mounting plate 2 has the function of connecting the door hinge 8 and the body sheet metal 7. The mounting plate 2 needs to be designed to conform to the body sheet metal 7 to ensure effective fit between the contact surfaces of the two, increase the connection strength of the structure, and improve the reliability of the structural connection.

[0032] After the above structure is installed, the DMU is used to simulate the movement trajectory of the door. In the process of the door moving from the closed state to the maximum open angle state, the requirement that the clearance between the door moving parts and the hinge moving parts and the surrounding area is greater than or equal to 3mm is met, ensuring the installation accuracy of the door.

[0033] The mounting plate 2 and the reinforcing seat 1 are connected to the outer side and the inner side of the body sheet metal 7 respectively, and can be connected to the body sheet metal 7 respectively by bolts or screws. The mounting plate 2 and the reinforcing seat 1 can also be connected to the body sheet metal 7 by the same bolt or screw. The mounting plate 2 and the body sheet metal 7 can be connected in a multi-point manner to ensure the connection strength of the structure. The reinforcing seat 1 can be connected in a multi-point manner or can be fixedly connected in combination with welding.

[0034] In some possible implementations, the above-mentioned characteristic mounting plate 2 and the reinforcement seat 1 are used as follows Figures 2 to 6 See the structure shown. Figures 1 to 3 The mounting plate 2 and the reinforcing seat 1 are both connected to the body sheet metal 7 through a first connecting member 61, and the first connecting member 61 is sequentially arranged through the reinforcing seat 1, the body sheet metal 7 and the mounting plate 2.

[0035] In this embodiment, a first connecting member 61 is provided through the reinforcing seat 1, the body sheet metal 7 and the mounting plate 2. The three are reliably connected through the first connecting member 61, thereby achieving effective locking of the relative positions of multiple components, simplifying the connection structure, facilitating the reasonable arrangement of the connection points, and ensuring the connection strength.

[0036] In some embodiments, the above-mentioned feature reinforcement seat 1 can be used as follows Figures 4 to 6 See the structure shown. Figures 4 to 6 The upper and lower side edges of the reinforcing seat 1 are bent toward the inner side of the vehicle body to form a horizontal portion 11, the front and rear side edges of the reinforcing seat 1 are bent toward the inner side of the vehicle body to form a bent portion 12, the upper and lower side edges of the bent portion 12 are extended toward the horizontal portion 11 to form connecting ears 13, and the horizontal portion 11, the bent portion 12 and the reinforcing seat 1 enclose a side cavity 14 whose opening faces the inner side of the vehicle body.

[0037] In this embodiment, the reinforcement seat 1 is formed by bending sheet metal, and a horizontal portion 11 and a bent portion 12 are formed on the four sides of the reinforcement seat 1. The connecting ear 13 on the bent portion 12 is connected to the horizontal portion 11, so that the reinforcement seat 1 forms a side cavity 14 with an opening facing the inner side of the vehicle body, so that the reinforcement seat 1 forms a structural support for the vehicle body sheet metal 7, enhances the structure's ability to resist deformation, and provides a reliable installation foundation for the installation of the door hinge 8.

[0038] Specifically, the connecting ear 13 is connected to one side of the horizontal portion 11 close to the side cavity 14, forming a supporting effect from the inside of the side cavity 14, thereby enhancing the structural strength of the reinforcing seat 1, ensuring the structural reinforcement of the mounting point of the vehicle body sheet metal 7, improving the structural rigidity of the mounting position, ensuring the installation accuracy of the door hinge 8, and improving the smoothness of the door opening and closing action.

[0039] For some possible implementations, see Figures 1 to 3 The door hinge reinforcement structure also includes a first step 71 arranged on the outer side wall of the vehicle body sheet metal 7, and the mounting plate 2 has an upper extension portion 21 extending forward to above the first step 71, and the bottom wall of the upper extension portion 21 is attached to the top wall of the first step 71, and the upper extension portion 21 is connected to the first step 71 through a second connecting member 62.

[0040] In this embodiment, the first step 71 provides a mounting foundation for the upper extension 21 on the basis of enhancing the structural strength of the vehicle body sheet metal 7.

[0043] In some embodiments, see Figure 4 and Figure 5The door hinge reinforcement structure also includes a reinforcement plate 3 connected to the inner side of the body sheet metal 7. The reinforcement plate 3 is located on the front side of the reinforcement seat 1. The reinforcement plate 3 extends downward from the inner side wall of the first step 71 to correspond to the inner and outer sides of the lower extension portion 22. The third connecting member 63 sequentially penetrates the lower extension portion 22, the body sheet metal 7 and the reinforcement plate 3.

[0044] In this embodiment, the reinforcing plate 3 is arranged inside the body sheet metal 7 and located in front of the reinforcing seat 1. The reinforcing plate 3 can structurally reinforce the installation position of the lower extension part 22 to ensure the structural strength of the connection point between the lower extension part 22 and the body sheet metal 7.

[0045] The third connecting member 63 not only connects the lower extension 22 and the body sheet metal 7, but also penetrates the reinforcing plate 3 inwardly, so that the lower extension 22, the body sheet metal 7 and the reinforcing plate 3 are connected as a unified whole, thereby improving the integrity of the structure. The third connecting member 63 is a bolt, and a projection welding nut is pre-arranged on the inner side wall of the reinforcing plate 3, so that the third connecting member 63 can be inserted from the outside for connection.

[0046] On this basis, a fourth connecting member 64 is further provided between the reinforcing plate 3 and the body sheet metal 7. There are multiple fourth connecting members 64, which are respectively located at the outer position of the third connecting member 63, so that the reinforcing plate 3 can be reliably lined on the inner side of the body sheet metal 7 to ensure the structural reinforcement effect.

[0047] In some embodiments, the above-mentioned feature reinforcement plate 3 can be used as follows Figure 7 See the structure shown. Figure 7 The reinforcing plate 3 is provided with reinforcing ribs 31 protruding toward the inner side of the vehicle body. The reinforcing ribs 31 are provided in a plurality and extend in the up-down direction respectively. The reinforcing ribs 31 can further enhance the structural strength of the reinforcing plate 3 and ensure the structural reinforcement effect on the vehicle body sheet metal 7.

[0050] The mounting plate 4 is integrally formed on the mounting plate 2, and the surface of the mounting plate 4 is perpendicular to the surface of the mounting plate 2. The angle of the mounting plate 4 is adjusted according to the installation requirements of the connecting shaft to meet the movement requirements of the door hinge 8 and ensure the smoothness of the door opening and closing movement.

[0051] In some possible implementations, the second shaft seat of the above feature is adopted as follows Figures 1 to 3 See the structure shown.
