Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, specifically to a C-pillar reinforcement plate for automobiles. Background Technology

[0002] In the field of modern automotive engineering, with the continuous improvement of vehicle performance requirements and increasingly stringent safety regulations, the strength and stability of the vehicle body structure have become key design considerations. As an important component of the vehicle body, the C-pillar connects the roof, the rear of the body, and the chassis, bearing a variety of complex mechanical loads.

[0003] The prior art discloses a C-pillar reinforcement plate for automobiles, with publication number CN210526654U. It includes a lower C-pillar panel and an upper C-pillar panel. A fixing hole is fixed to one side of the lower C-pillar panel, and a first positioning hole is fixed to the side of the lower C-pillar panel near the fixing hole. A weight-reducing hole is also fixed to the side of the lower C-pillar panel near the first positioning hole. In this C-pillar reinforcement plate, the lower C-pillar panel can be fixed to the C-pillar via the fixing hole and the first positioning hole. After the lower C-pillar panel is fixed, the weight is distributed across the C-pillar through the weight-reducing hole. The upper C-pillar panel can also be fixed to the C-pillar via a second positioning hole and a locking nut plate. After the upper C-pillar panel is fixed, the weight is distributed through a V-shaped load-bearing groove. This allows the C-pillar reinforcement plate to reduce weight through the clever weight-reducing structure of the weight-reducing hole and the load-bearing groove, and also strengthens the car body.

[0004] The aforementioned automotive C-pillar reinforcement plate allows the upper panel of the C-pillar to be fixed to the C-pillar. After the upper panel is fixed, the weight can be distributed through the V-shaped load-bearing groove. The C-pillar reinforcement plate can reduce weight through the weight-reducing holes and the clever weight-reducing structure of the load-bearing groove itself, and can also strengthen the car body. However, the aforementioned automotive C-pillar reinforcement plate does not have high-strength protective material on its surface, and cannot effectively resist the huge tensile force generated by the vehicle during collision or torsion. Its protective strength is low, and its performance in use is not good. Improvements are needed. Utility Model Content
