Problems solved by technology

[0003] At present, the design of the static stiffness of the inner sheet metal of the car door only stays on the thickness of the inner sheet metal of the car door. The sheet metal parts have a large area, large holes and a large number of holes, and some accessories are directly installed in the door. On the sheet metal, the load of the inner sheet metal is increased, which further reduces the static stiffness of the door inner sheet metal

Abstract

The invention discloses a static rigidity reinforcing structure of a metal plate in a vehicle door, which comprises transverse reinforcing ribs, vertical reinforcing ribs and peripheral reinforcing ribs, wherein the transverse reinforcing ribs comprise a first transverse reinforcing rib, a second transverse reinforcing rib, a third transverse reinforcing rib and a fourth transverse reinforcing rib, the first transverse reinforcing rib and the second transverse reinforcing rib are arranged on the upper portion of the door metal plate, the first transverse reinforcing rib is communicated with the second transverse reinforcing rib, the third transverse reinforcing rib is arranged on the lower portion of the door metal plate, the fourth transverse reinforcing rib is arranged in the middle of the door metal plate, the vertical reinforcing ribs comprise the first vertical reinforcing rib and the second vertical reinforcing rib, the first vertical reinforcing rib is arranged on the lower portion of the door metal plate, the second vertical reinforcing rib penetrates through the door metal plate in the vertical direction, and the peripheral reinforcing ribs are arranged on the periphery of the door metal plate in the vehicle. According to the static rigidity reinforcing structure of the metal plate in the vehicle door, the static rigidity of the metal plate in the vehicle door can be improved, the tremor sound of the metal plate in the vehicle door during door closing is eliminated, and the sound quality of door closing is improved.

Description

technical field [0001] The invention relates to the technical field of automobile doors, in particular to a static stiffness strengthening structure of a sheet metal inside a door. Background technique [0002] With the improvement of living standards, automobiles have become an indispensable means of transportation in life. Car sound quality is an important factor for customers to choose. Among the sound quality of many vehicles, the door closing sound quality of the vehicle has attracted the attention of a large number of OEMs and research institutions. To evaluate the quality of the door closing sound, there is currently a lack of research on how to control the sound quality of the door closing. [0003] At present, the design of the static stiffness of the inner sheet metal of the car door only stays on the thickness of the inner sheet metal of the car door. The sheet metal parts have a large area, large holes and a large number of holes, and some accessories are direct...
