Description
Technical Field
The invention relates to a force transmission structure, in particular to a front end force transmission structure of an electric vehicle.
Background
The front collision performance of the automobile is taken as one of the automobile safety performance evaluation indexes in all countries. In the front collision process, whether the front cabin can effectively absorb and transmit collision energy is particularly critical. If the collision energy transmitted to the dash panel is too large, the vehicle occupant is directly injured. In order to resist the impact force from the front during the frontal collision of the conventional automobile, a floor longitudinal beam is generally arranged at the lower end of a floor and is overlapped with the root of a front longitudinal beam, so that the force is transmitted to the rear part of the automobile body, and the passenger compartment is protected.
Because pure electric vehicles's special construction, the power battery needs to be installed to the floor lower extreme, because the space is limited, the floor lower extreme is difficult for arranging floor biography power longeron, causes the root intensity of front longitudinal to be weak, and the collision effort can not effectively be transmitted, causes preceding enclose to invade seriously, and this collision security performance to the vehicle influences greatly.
