The features in the following embodiments and implementation manners can be combined with each other without conflict.
[0033] As Figure 1 andFigure 2 shown, Figure 1 is a structural schematic diagram of a windshield crossbeam assembly and a front wall according to an exemplary embodiment of the present application, Figure 2 is an A-A cross-sectional view of a windshield crossbeam assembly and a front wall according to an exemplary embodiment of the present application. The present application provides a windshield crossbeam assembly 1, which can be applied to a vehicle. The windshield crossbeam assembly 1 comprises a first crossbeam 2 and a second crossbeam 4. The first crossbeam 2 is provided with an opening 3 extending along a first direction X1. The opening direction of the opening 3 is perpendicular to the first direction X1. The second crossbeam 4 is connected to the first crossbeam 2 and is located below the opening 3. The second crossbeam 4 forms a closed cavity 5 below the opening 3. It should be noted that the windshield crossbeam assembly 1 is applied to the front of the vehicle body, and the first direction X1 is the width direction of the vehicle body. The first crossbeam 2 can extend along the width direction of the vehicle body, and the opening 3 extends along the width direction of the vehicle body. The opening direction of the opening 3 is perpendicular to the width direction of the vehicle body and faces the rear of the vehicle. The front windshield of the vehicle can be connected to the upper part of the first crossbeam 2. The closed cavity 5 formed by the second crossbeam 4 is located below the opening 3 of the first crossbeam 2, which can optimize the space of the vehicle body. The opening 3 structure of the first crossbeam 2 can reduce the injury value of pedestrian head impact and meet the requirements of pedestrian protection. When the vehicle collides with the pedestrian, the front windshield is usually the area that the pedestrian's head is most likely to contact. The first crossbeam 2 serves as a deformation energy-absorbing element to absorb the impact energy transmitted from the front windshield. The opening 3 structure of the first crossbeam 2 can provide sufficient Z-direction deformation space when the pedestrian's head collides, reducing the injury value of pedestrian head impact and meeting the requirements of pedestrian protection. The closed cavity 5 of the second crossbeam 4 can meet the requirements of the overall vehicle torsional stiffness and the vehicle body NVH.
