AI Technical Summary

Technical Problem

How to improve the vertical stiffness of car doors to enhance their performance? Existing technologies suffer from stress concentration and insufficient structural stiffness at the hinge connections of car doors.

Method used

By introducing a first reinforcing column into the vehicle body frame, and connecting the upper and lower door hinges to the upper and lower parts of the first reinforcing column respectively, combined with the design of fasteners and joints, an integrated structure is formed to share the load, thereby enhancing the overall structural rigidity and the local rigidity of the hinge mounting area.

Benefits of technology

It improves the vertical stiffness of the door, reduces stress concentration at the hinge, reduces the number of parts, improves the integration of parts and assembly efficiency, and enhances the door's resistance to deformation.

Abstract

The application provides a vehicle, which comprises a vehicle body frame, the vehicle body frame comprising: a frame beam body having a first side facing an inner side of the vehicle body and a second side facing an outer side of the vehicle body; a first reinforcing column filled in the first side of the frame beam body; an upper door hinge and a lower door hinge respectively installed at an upper portion and a lower portion of the first reinforcing column and used for connecting a door to the vehicle body frame. Since the upper door hinge and the lower door hinge are connected to the first reinforcing column to form an integrated structure, the ability of the upper door hinge and the lower door hinge to resist a sagging load of the vehicle body can be improved, and the vertical stiffness of the door is improved.
