Embodiment Construction

[0034] see figure 1 and Figure 5 , the front end structure of the vehicle force transmission path of the present invention can be used to improve vehicle collision safety performance, the front end structure of the vehicle force transmission path is mainly composed of a vehicle body beam 10, at least one vehicle body energy absorbing part 20, an LLP (low loadpath) beam and at least one LLP absorber Can be made up of 40 parts. Wherein, the vehicle body cross member 10 can be installed on the front end of the vehicle frame 61 , specifically, the vehicle body cross member 10 can be connected with the longitudinal beam at the front end of the vehicle frame 61 . At least one body energy absorber 20 is mounted on the body cross member 10 , the body energy absorber 20 being arranged towards the vehicle frame 61 . A force transmission channel can be formed by the cross member 10 of the vehicle body and the energy-absorbing member 20 of the vehicle body. When the vehicle collides, a...

Abstract

The invention provides a vehicle force transmission path front end structure and a vehicle, and the structure comprises a vehicle body cross beam which is disposed at the front end of a vehicle frame;at least one vehicle body energy absorption piece which is arranged on the vehicle body cross beam and is arranged towards the vehicle frame, so that at least one part of energy is absorbed through the vehicle body energy absorption piece during vehicle collision; an LLP cross beam which is arranged in a spaced mode with the vehicle body cross beam, and the LLP cross beam is arranged at the frontend of the auxiliary frame; and at least one LLP energy absorption piece which is arranged on the LLP cross beam and is arranged towards the auxiliary frame, and the LLP cross beam and the LLP energyabsorption piece form an LLP force transmission channel so that collision energy can be further absorbed through the LLP energy absorption piece in the vehicle collision process. According to the vehicle force transmission path front end structure, collision load distribution is optimized, when a vehicle collides, the two force transmission channels can make contact with a counterguard at the same time, the stress pressure difference of the upper portion and the lower portion of a counterguard assessment area is balanced, the breakdown risk caused by a single force transmission path is reduced, and the vehicle collision safety performance is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a vehicle force transmission path front end structure and a vehicle with the force transmission path front end structure. Background technique [0002] At present, most of the existing models only have a vehicle body force transmission path or are equipped with a short sub-frame structure as the second force transmission path, and the sub-frame beam is relatively short and does not extend to the position of the vehicle body beam. In the early stage of the collision process, only the front beam of the vehicle body and the energy-absorbing box are the main deformed energy-absorbing parts and are in contact with the barrier. Therefore, the cross-sectional force of the force transmission path of traditional vehicles is relatively large to meet the requirements of safety objectives such as frontal collision and offset collision. Therefore, the single and strong front fo...
