Description

Technical Field

[0001] The utility model belongs to the field of automobile frames, and specifically relates to a front section structure of a frame. Background Art

[0002] The front section structure of the automobile frame has always been a development system that automobile manufacturers have focused on. The strength of the old front section structure of the frame is relatively weak, and the beam is connected to the floor panel, which cannot meet the requirements of the head-on collision test. As safety regulations become increasingly stringent, the front section structure of the frame must be strengthened to meet the requirements of the head-on collision regulations. As people's awareness of the safety requirements for car use increases, the safety performance of the vehicle is also one of the selection points for people to choose a car. The head-on collision test safety of the car will provide excellent safety protection for the occupants during a head-on collision. Therefore, there is an urgent need to develop a front section structure of the frame with high structural strength.

[0003] To address the aforementioned issues, Patent Document 208931432U discloses a front section of a longitudinal beam for an automobile. This vehicle absorbs collision energy through deformation of the front section. The utility model connects a groove plate to the outer plate end of the front section of the longitudinal beam. The groove plate is positioned in a position with ample room for deformation. The groove plate is provided with a groove, minimizing the cross-sectional area of ​​the front section of the longitudinal beam at the groove and minimizing its strength. Furthermore, the groove plate is made of a relatively low-strength material. When the front section of the longitudinal beam is impacted by an external force, the groove plate deforms more significantly at the groove, resulting in better collision energy absorption.
