The invention relates to an automobile front assembly which comprises a front longitudinal beam, threshold boundary beams, a front wall plate and a front wall plate lower cross beam, the front wall plate lower cross beam is fixed on the front wall plate, the front wall plate lower cross beam is fixedly connected with the front longitudinal beam, and the front wall plate lower cross beam is fixedly connected with the corresponding threshold boundary beams. According to the structure, the problem of a force transmission channel is solved, the front floor upper reinforcing longitudinal beams are additionally arranged on the two sides of the front floor on the rear portion of the front longitudinal beams, the effect of transmitting direct impact force is achieved, meanwhile, the front floor middle section is additionally arranged on the front floor structure, and the effect of transmitting the direct impact force from the middle position of the front floor is achieved; in this way, five force transmission paths are formed, the front collision force is effectively dispersed, the requirements of various power assemblies are met, and meanwhile the strict requirements of CNCAP-five stars are met.
Description
technical field [0001] The invention relates to the technical field of automobile engineering, in particular to the technology of vehicle body. Background technique [0002] In order to increase the cruising range and increase the space for the power battery, the power battery is generally installed on the bolts at the bottom of the sill side beam. Due to the difficulty and cost of reducing the thickness of the power battery in the existing technology, it is temporarily impossible to reduce the thickness of the power battery. At the same time, in order to reduce the height of the whole vehicle, the floor needs to be pressed very low, resulting in the absence of the longitudinal beams at the bottom of the front floor, and only the front longitudinal beams are retained. Therefore, when a frontal collision occurs, the frontal impact force cannot be transmitted to the sill side beams through the longitudinal beams under the front floor, resulting in stress concentration on the f...
