Reinforcement structure of subframe for injury improvement in frontal collision

摘要

The present invention aims to lower passenger injury by minimizing subframe deformation by reducing body acceleration during frontal collision by installing a high-strength reinforcement member on the subframe.;In order to achieve the above object, the present invention is to mount a V-shaped reinforcement (2) in the sub-frame (1) in a conventional sub-frame (1) on which the engine and the chassis, etc., the reinforcement Both end portions 2a and 2c of (2) are fixed to predetermined portions of both inner wall portions 1a and 1c of the subframe 1, and the center portion 2b of the reinforcement 2 is It is characterized by being in contact with the front inner wall portion 1b of the subframe 1.;Therefore, according to the present invention, since the V-shaped reinforcement is mounted on a predetermined portion of the existing subframe, the rigidity is strengthened, thereby minimizing the deformation of the subframe during frontal collision, thereby preventing the lower arm and the engine from rapidly pushing into the cabin. It is a useful design that can lower the passenger injury by maximally protecting indoor passengers.
