[0021] As shown in the accompanying Figure 1 to the accompanying Figure 3 As shown in the accompanying

[0022] The utility model provides a kind of reinforcing plate for door hinge, including upper end reinforcing plate 1, middle end reinforcing plate 2, lower end reinforcing plate 3, positioning hole 4, end plate mounting hole 5, mounting boss 7, fitting surface 8, collapse hole group 9 and middle end mounting hole 10, the upper end reinforcing plate 1, middle end reinforcing plate 2 and lower end reinforcing plate 3 are installed together by connecting piece, and are fixed with door, wherein the upper end reinforcing plate 1 and lower end reinforcing plate 3 are provided with positioning hole 4 in a corner, and the edge is provided with the end plate mounting hole 5 required for installation and is penetrated;The upper end reinforcing plate 1 and lower end reinforcing plate 3 are provided with mounting boss 7 and fitting surface 8;The middle end mounting hole 10 is penetrated in the four corners of the middle end reinforcing plate 2 respectively, wherein the middle end mounting hole 10 is penetrated with two groups of the collapse hole group 9 between them.

[0023] Further, the upper end reinforcing plate 1 and the lower end reinforcing plate 3 are consistent in structure, and the reinforcing rib plate 6 is provided in an integrated manner at the end away from the middle end reinforcing plate 2. The skin thickness of the reinforcing rib plate 6 is greater than that of the upper end reinforcing plate 1 and the lower end reinforcing plate 3. In terms of material selection, high-strength alloy steel such as Q460 can be selected, which can enhance the structural strength of the end of the reinforcing plate and effectively resist stress generated when the door is frequently opened and closed or subjected to external impact, thereby ensuring the overall stability of the door hinge reinforcing plate.

[0024] Further, the upper end reinforcing plate 1 and the lower end reinforcing plate 3 are provided with mutually intersecting "cross" reinforcing ribs at the bending portions. This reinforcing rib structure can significantly improve the strength of the bending portions of the reinforcing plate, effectively disperse stress, and prevent deformation or damage caused by stress concentration. The reinforcing rib is also made of the same high-strength aluminum alloy material as the main body of the reinforcing plate, which can ensure strength and reduce overall weight, meeting the needs of lightweight design of automobiles.

[0025] Further, the middle end mounting hole 10 provided on the middle end reinforcing plate 2 corresponds to the end plate mounting hole 5 provided at one end of the upper end reinforcing plate 1 and the lower end reinforcing plate 3. High-strength bolts of M8 specification can be used as connecting pieces, which can smoothly pass through the corresponding middle end mounting hole 10 and end plate mounting hole 5, firmly connecting the three reinforcing plates together. Through precise hole design and matching, the convenience and accuracy of the installation process are ensured, and the stability of the connection is also guaranteed, reducing the shaking and abnormal noise of the door during use.

[0026] Further, the middle-end mounting hole 10 of the lower-end reinforcing plate 3 is located on one side of the collapse hole group 9, and the collapse hole group 9 is close to the connection of the upper-end reinforcing plate 1, the middle-end reinforcing plate 2 and the lower-end reinforcing plate 3. When the vehicle is in collision, the collapse hole group 9 can deform preferentially to absorb the collision energy, and the position design of the middle-end mounting hole 10 ensures that even if the collapse hole group 9 deforms, it will not affect the normal work of the connecting piece, ensuring the stability of the connection between the reinforcing plates.

[0027] Further, the collapse hole group 9 is composed of a plurality of inclined through holes, which are distributed along the shape of the middle-end reinforcing plate 2, and the inclination angle is 45°. Through this special structure design, when the vehicle is in collision, the collapse hole group 9 can deform in a predetermined manner to effectively absorb and disperse the collision energy, improve the passive safety performance of the vehicle, and provide more reliable safety protection for the passengers in the vehicle, which are distributed along the shape of the middle-end reinforcing plate 2.

[0028] The installation steps are as follows: first, the positioning hole 4 at one corner of the upper-end reinforcing plate 1 and the lower-end reinforcing plate 3 plays a key role, and the maintenance personnel can use tools such as positioning pins to quickly and accurately determine the installation position of the reinforcing plate on the door through the positioning hole 4 to achieve preliminary positioning. Then, use high-strength bolts of M8 specification to pass through the middle-end mounting hole 10 at the four corners of the middle-end reinforcing plate 2, and the end plate mounting hole 5 at the edge of the upper-end reinforcing plate 1 and the lower-end reinforcing plate 3, to firmly connect the three reinforcing plates and fix them with the door. The mounting boss 7 and the matching surface 8 can ensure that the reinforcing plate is closely matched with the door, further improving the stability of the installation.

[0029] During the daily use of the door, various stresses will be generated due to the frequent opening and closing of the door. At this time, the reinforcing rib plate 6 plays an important role. Because it is made of high-strength alloy steel such as Q460, and the skin thickness is greater than that of the upper-end reinforcing plate 1 and the lower-end reinforcing plate 3, it can effectively resist the stress generated when the door is frequently opened and closed or subjected to external impact, enhance the structural strength of the end of the reinforcing plate, and ensure the overall stability of the door hinge reinforcing plate. At the same time, the "cross" reinforcing ribs that cross each other at the bending parts of the upper-end reinforcing plate 1 and the lower-end reinforcing plate 3 can significantly improve the strength of the bending parts, effectively disperse the stress, and prevent deformation or damage caused by stress concentration. Because the reinforcing rib is made of high-strength aluminum alloy material, it not only ensures the strength but also reduces the overall weight, which meets the design requirements of automobile lightweight.

[0030] When the vehicle is in collision, the collapse hole group 9 becomes the key structure to ensure the safety of the people in the vehicle. The collapse hole group 9 is close to the connection of the three reinforcing plates, and is composed of a plurality of through holes distributed along the shape of the middle end reinforcing plate 2, and the inclination angle is 45°. The impact force generated by the collision is first transmitted to the collapse hole group 9, and due to the special structure design, it can preferentially deform in a predetermined manner, effectively absorbing and dispersing the collision energy. While the middle end mounting hole 10 opened in the lower end reinforcing plate 3 is located on one side of the collapse hole group 9, even if the collapse hole group 9 deforms, it will not affect the normal work of the connecting parts such as high-strength bolts, ensure the stability of the connection between the reinforcing plates, and further provide more reliable safety protection for the passengers in the vehicle.

[0031] The technical scheme of the utility model, or the technical scheme of the utility model inspires the person skilled in the art, designs similar technical scheme, and achieves the above technical effect, and all falls into the protection scope of the utility model.
