Description

Reinforcing panels for door hinges, doors and vehicles

technical field

The utility model relates to the technical field of vehicles, in particular to a reinforcement plate used for a door hinge, a car door and a vehicle.

Background technique

As customers have higher requirements on the quality of vehicles, the quality of door opening and closing directly affects the comfort of customers, and is one of the important conditions that determine customers' awareness of automobile brands. The key factors in the assessment of the quality of the door opening and closing of the car are whether the rigidity, structural design, and opening and closing force performance of the door meet the requirements.

Taking a car as an example, in the general car body structure, there are roughly two connection methods for the door hinge connection: bolt connection and welding. These two connection methods lead to stress concentration at the joint of the door hinge, and the hinge reinforcement structure is often required. At present, the common reinforcing plate used for the door hinge is that the reinforcing plate is bonded and welded on the inner panel of the automobile door, and the reinforcing plate is a flat plate with low strength. Due to the particularity of its installation position, this kind of reinforcement plate bears a large pressure, the stress is too concentrated, and the reinforcement plate is too weak. When the pressure is applied, the residual deformation is too large, which will cause the car door to sag, and then cause the car door to sag. Closing is difficult or impossible.

How to realize the strengthening of the joint of the door hinge without increasing the weight of the door, so as to finally meet the overall rigidity of the door is a problem to be solved.
