Description

Structure capable of improving side collision resistance of automobile body Technical Field The invention relates to the technical field of anti-collision of automobile bodies, in particular to a structure capable of improving the anti-side collision performance of automobile bodies. Background The existing automobile body and the chassis are fixedly connected through A, B and C columns, and the Chinese patent with publication number CN113879245A discloses an active automobile side collision buffer device. The device is arranged in the seat and comprises a control device, an environment sensing device, an executing device, a buffer device and an audible and visual warning device. The automobile detects the side environment of the automobile through the environment sensing device, the collected information is transmitted to the control device, and the control device sends out instructions to the execution device after analyzing the collected information. The actuating device comprises a permanent magnet, an electromagnet formed by an iron core and a spiral coil, a connecting rod, a piston and the like, wherein the piston is connected with the permanent magnet, the rear of the piston is connected with the connecting rod, and the sleeve is fixed in the seat.
