Technical Field
[0001] The utility model relates to the technical field of automobile bodies, in particular to an A-pillar reinforcement plate structure. Background Art
[0002] The 25% frontal small offset test was introduced by the Insurance Institute for Highway Safety (IIHS) in its new car safety evaluation in 2012. The percentage refers to the overlap between the width of the vehicle body and the barrier. The smaller the overlap, the smaller the contact force area, and the higher the damage to the vehicle body and occupants. The way to judge the quality of the vehicle body is generally to record and analyze the deformation of the vehicle body during and after the collision, and combine the damage values of various parts of the dummy to judge the protection ability of the vehicle body to the occupants. In general, affected by the vehicle shape, vehicle layout and body structure, the target value can often be achieved through minor changes. On the premise that the cross-section of the A-pillar and the door sill is not increased, in order to ensure that the collision force can be stably transmitted and dispersed to the A-pillar and the door sill, and reduce the intrusion of small offset collisions, it is necessary to invent a new A-pillar reinforcement plate structure. Utility Model Content

[0006] Furthermore, the front and rear ends and the lower end of the reinforcing support plate are fixedly connected to the inner wall of the I-shaped groove of the A-pillar reinforcing plate.
[0007] Furthermore, a front bending edge is provided at the front end of the reinforcing support plate, and the front bending edge is fixedly connected to the A-pillar reinforcing plate.
[0008] Furthermore, a rear bending edge is provided at the rear end of the reinforcing support plate, and the rear bending edge is fixedly connected to the A-pillar reinforcing plate.
[0009] Furthermore, lower bending edges are bent on both sides of the lower end of the reinforcing support plate, and the lower bending edges are fixedly connected to the A-pillar reinforcement plate.
[0010] Furthermore, the upper end of the reinforcing support plate is fixedly connected to the outer side of the A-pillar inner plate.
[0011] Furthermore, the upper end of the reinforcing support plate is provided with a plurality of groups of positioning holes for welding positioning.
[0012] Furthermore, the width of the reinforcing support plate gradually transitions from wide to narrow from front to back.
[0013] Furthermore, weight-reducing holes are provided on both sides of the reinforcing support plate.
