Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts, and in particular relates to a wiper reinforcement plate and a rear door reinforcement assembly. Background Art

[0002] The tailgate wiper is an assembly part with a certain mass on the car. When it is installed on the tailgate sheet metal, it not only has to bear the weight of itself and other components such as the wiper arm and wiper blade, but also has to withstand the vibration, bumps and other forces generated during the vehicle's driving. If the mounting point of the tailgate sheet metal is not rigid enough, the wiper may not be installed firmly, and it may become loose, shake or even fall off during use, which will affect the normal use of the wiper, reduce its service life, and may also pose a potential threat to the normal operation and safety of the vehicle.

[0003] Conventional tailgate reinforcement methods focus on increasing the normal stiffness of the mounting point on the sheet metal reinforcement plate. This is typically achieved by increasing the plate's thickness, changing its shape, or adding ribs. For example, thicker steel plates are used for the wiper mounting reinforcement plate, or protrusions or ribs are added to the plate to increase the strength and stiffness of the mounting point in the normal direction and prevent excessive vertical deformation.

[0004] However, the existing methods ignore the characteristics of the wiper as a moving brush-mounted part, that is, when the wiper is working, the wiper arm will drive the wiper blade to perform a reciprocating swinging motion, which requires that the installation point of the wiper has not only sufficient normal stiffness, but also good tangential stiffness; as the wiper swings, the installation point is deformed in the tangential direction, causing the movement trajectory of the wiper blade to shift, making it impossible to accurately clean the windshield, thereby affecting the cleaning effect of the wiper; at the same time, long-term tangential deformation will also cause fatigue of the wiper installation components, accelerate the wear and damage of the components, and reduce the overall performance and service life of the wiper.
