轿车前纵梁内板
摘要：
本实用新型轿车前纵梁内板，解决了现有轿车前纵梁结构比较复杂，车身零部件数量多，成本高，安全性差的问题。轿车前纵梁内板包括前纵梁内板前部和前纵梁内板后部，所述前纵梁内板前部厚度为1.5毫米，前纵梁内板后部厚度为2.0毫米，且前纵梁内板前部和车前纵梁内板后部之间为激光拼焊连接。本实用新型节约了原材料，减少了冲压工序以及车身零部件数量，降低了汽车的生产成本，通过选用不同厚度的材料，并采用激光拼焊连接改良了轿车前纵梁内板结构，在撞击过程中，可以控制更多的能量得到吸收，从而改良车身部件的抗击冲撞能力，提高车身的被动安全性。
摘要（英）：

The utility model provides a car front longitudinal beam inner plate which solves the problems that the car front longitudinal beam structure is more complicated in the prior art; the number of vehicle body parts is great; the cost is high, and the safety is poor. The car front longitudinal beam inner plate comprises a front longitudinal beam inner plate front part and a front longitudinal beam inner plate rear part; the thickness of the front longitudinal beam inner plate front part is 1.5 mm, and the thickness of the front longitudinal beam inner plate rear part is 2.0 mm; the front longitudinal beam inner plate front part is connected with the front longitudinal beam inner plate rear part through laser butt welding. The car front longitudinal beam inner plate saves source material, reduces the punching processes and the number of vehicle body parts, and reduces the production cost of the vehicle; materials with different thicknesses are used; the car front longitudinal beam inner plate structure is improved through the laser butt welding connection, so more energy is controlled to be absorbed in the collision process; thereby, the anti-collision capability of the vehicle body parts is improved, and the passive safety of the vehicle body is improved.
