For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

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

[0022] The high-strength automobile door lock reinforcing plate provided by the present application comprises a door lock reinforcing plate body 1, vertical reinforcing ribs 2, first reinforcing ribs 3, second reinforcing ribs 4, first bending parts 5, second bending parts 6, third bending parts 7, wrapping reinforcing rods 8, avoiding holes 9 and bolt holes 10. The door lock reinforcing plate body 1 is provided with vertical reinforcing ribs 2, first reinforcing ribs 3 and second reinforcing ribs 4 on three surfaces respectively. The edges of the door lock reinforcing plate body 1 are bent to form the first bending parts 5, the second bending parts 6 and the third bending parts 7. The wrapping reinforcing rods 8 are wrapped in the first bending parts 5, the second bending parts 6 and the third bending parts 7. The door lock reinforcing plate body 1 is provided with avoiding holes 9 and bolt holes 10 on the surface.

[0023] Further, the vertical reinforcing rib 2 and the first reinforcing rib 3 are vertically arranged on the door lock reinforcing plate body 1, and are arranged on the side of each other. The cross-sectional shape of the vertical reinforcing rib 2 and the first reinforcing rib 3 can be designed as a trapezoidal shape to enhance the structural stability. In order to ensure sufficient strength, the material of these reinforcing ribs can be selected from high-strength alloy steel such as Q345 steel, which has good strength and toughness and can effectively improve the vertical bearing capacity of the door lock reinforcing plate body 1.

[0024] Further, a plurality of first reinforcing ribs 3 are arranged perpendicular to the second bending part 6, a plurality of second reinforcing ribs 4 are arranged perpendicular to the first bending part 5, and the first reinforcing ribs 3 and the second reinforcing ribs 4 are arranged on the adjacent two surfaces of the door lock reinforcing plate body 1. The spacing of the first reinforcing ribs 3 and the second reinforcing ribs 4 can be adjusted according to the size and stress condition of the door lock reinforcing plate body 1. Their cross-sectional dimensions are similar to those of the vertical reinforcing rib 2 and the first reinforcing rib 3, and are also made of Q345 steel to ensure that they effectively reinforce the door lock reinforcing plate body 1 in different directions.

[0025] Further, the first bending part 5, the second bending part 6 and the third bending part 7 are arranged on one side of the door lock reinforcing plate body 1 and below it, and the second bending part 6 and the third bending part 7 allow a prefabricated base surface to be provided for the door lock. The three bending parts can be processed by sheet metal technology, and the material is selected from the same galvanized steel sheet as the door lock reinforcing plate body 1. The size of the prefabricated base surface is determined according to the model and installation requirements of the door lock, improving the convenience and stability of installation.

[0026] Further, the first bending part 5, the second bending part 6 and the third bending part 7 are in the shape of "L" as a whole, and the cross-section is in the shape of "U". This unique shape design not only enhances the strength of the bending part itself, but also better cooperates with other components. The depth of the "U" shaped cross-section is 8-12mm, and the width is 10-15mm, ensuring the maximum structural strength in a limited space, while meeting the installation needs of the wrapping reinforcing rod 8.

[0027] Further, the first bending part 5, the second bending part 6 and the third bending part 7 allow the wrapping reinforcing rod 8 to be limited, and the wrapping reinforcing rod 8 is located at the edge of the door lock reinforcing plate body 1. The wrapping reinforcing rod 8 can be made of solid aluminum alloy material, which has the characteristics of light weight and high strength, and can effectively enhance the strength of the edge of the door lock reinforcing plate body 1 while reducing the overall weight. Through the wrapping of the bending part, the wrapping reinforcing rod 8 is tightly combined with the door lock reinforcing plate body 1, further improving the anti-deformation ability of the entire reinforcing plate.

[0028] The working principle is as follows: when the automobile door lock is subjected to external force by the reinforcing plate, the parts work cooperatively, and the stability and reliability are ensured by reasonable structure design and material selection, effective dispersion and resistance to external force. When subjected to vertical force, the vertical reinforcing rib 2 and the first reinforcing rib 3 which are vertically arranged and have a trapezoidal cross section are made of Q345 high-strength alloy steel, and the two are matched with each other to uniformly disperse the vertical impact force generated by closing the door to the door lock reinforcing plate main body 1, so as to avoid local deformation and damage. When subjected to horizontal force, the first reinforcing rib 3 and the second reinforcing rib 4 which are arranged perpendicularly to the bending part are made of Q345 steel, and the horizontal force generated by the vehicle bumping or colliding is transmitted to the bending part and the main body part in the vertical direction, so as to reduce the influence of the horizontal force. The first bending part 5, the second bending part 6 and the third bending part 7 are in the shape of "L" and have a "U" shaped cross section, can disperse and transfer the force in each direction, transmit the vertical force to the wrapping reinforcing rod 8 when subjected to vertical force, and disperse to the adjacent part when subjected to horizontal force. The wrapping reinforcing rod 8 is made of solid aluminum alloy, can disperse force and reduce deformation when the edge is subjected to impact, is tightly combined with the main body through the bending part, and improves the anti-deformation capability. The avoiding hole 9 and the bolt hole 10 on the door lock reinforcing plate main body 1 affect the strength, but the reinforcing rib layout is reasonable, the force can be transmitted around the avoiding hole 9, and the strength around the bolt hole 10 is ensured.

[0029] The technical scheme disclosed by the utility model, or the technical scheme designed by the person skilled in the art under the inspiration of the technical scheme of the utility model, can achieve the above technical effects, and fall within the protection scope of the utility model.
