Description

Technical Field

[0001] This utility model belongs to the field of automobile door sill structure, specifically, this utility model relates to an automobile door sill post collision structure. Background Technology

[0002] Analysis of road traffic injury statistics shows that car collisions account for a significant proportion of injuries and fatalities. Due to the high lethality of side-impact pole collisions, some overseas countries and China have added pole impact tests. Given that the side panels of the vehicle body are the primary contact areas in side-impact pole collisions, their intrusion velocity, acceleration, intrusion depth, and deformation directly affect occupant injuries. Therefore, strengthening the structural design of the side panels and door sills is the most direct way to address pole impact test risks. Figure 3 and Figure 4 As shown, in the prior art, by using an aluminum alloy profile structure, the length of which covers the front area of ​​the front door and the middle area of ​​the rear door, the structure of the column impact position is the same as that of the non-column impact position. During the column impact process, the aluminum alloy profile collapses uniformly, failing to effectively strengthen the structure of the column impact area.

[0003] To address the aforementioned issues, patent application number 2024107822617 discloses a car sill beam reinforcement structure and a car sill beam structure. The car sill beam reinforcement structure is used to install in the cavity of the outer plate of the sill beam and is made of fiber-reinforced composite material. The car sill beam reinforcement structure includes: a reinforcing body with a cross-section along the direction intersecting the axial direction of the reinforcing body. The cross-section of the reinforcing body is C-shaped, and a first reinforcing spoke extends from the inner side of the reinforcing body toward the opening direction of the reinforcing body. However, this method cannot solve the aforementioned technical problems.

[0004] Therefore, in order to improve or solve at least one of the above problems, a car door sill pillar collision structure is provided that can effectively improve the structural strength of the pillar collision area, effectively reduce the intrusion speed, intrusion acceleration and intrusion amount during the pillar collision process, and effectively improve the safety factor of the occupants.
