Hinge reinforcement plate for front hatch cover of automobile

Abstract

The invention discloses an automobile front hatch cover hinge reinforcing plate.The automobile front hatch cover hinge reinforcing plate is provided with a main binding surface located near the middle of the reinforcing plate, a middle step surface located near the middle of the main binding surface, an upper step surface, a right step surface, a lower step surface, a left welding surface and a right welding surface, wherein a hinge installation hole is formed in the main binding surface, the upper step surface, the right step surface and the lower step surface are located on the periphery of the main binding surface, the upper step surface and the right step surface are located at the same altitude, and the upper step surface, the middle step surface and the lower step surface are located at different altitudes; the left welding surface and the right welding surface are located on the left side and right side of the lower step surface and the main binding surface, the upper step surface, the right step surface, the right welding surface, the lower step surface and the left welding surface are located on the periphery of the reinforcing plate in sequence, and welding spots are arranged on the middle step surface, the upper step surface, the right step surface, the right welding surface, the lower step surface and the left welding surface respectively.The problems of poor rigidity and strength and cracking of a front hatch cover hinge installation point are solved.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a hinge reinforcement plate of an automobile front hatch cover. Background technique [0002] The front hatch system is a relatively independent assembly in the car body structure, and it is an important channel for users to check and maintain the power system. The hinge is a structure that controls the rotation of the front hatch to realize the opening and closing of the front hatch. [0003] The front hatch hinge reinforcement plate is located between the hinge inner plate and the outer plate, and is generally welded with the inner plate. The hinge reinforcement plate plays a vital role in improving the mode of the front hatch, improving the NVH performance, improving the stiffness of the hinge installation point of the front hatch, and improving the lateral and torsional stiffness of the front hatch. [0004] In addition, when the front hatch is ...
