Description

  The present invention relates to a vehicle body front structure.

  The front body structure of an automobile absorbs initial energy by collapsing and deforming a crash box disposed on the axis of the front-rear frame member in the event of a frontal collision of the vehicle, and the axial seat of the front-rear frame member. There is one that stabilizes bending deformation (axial collapse) (see, for example, Patent Document 1). However, in the case of a frontal collision or the like of a vehicle having a front end shape mismatch such as a large vehicle and a small vehicle, the front-rear direction Combined with the concentrated axial load on the skeletal member, there is a possibility of insufficient interaction.

Therefore, the present applicant provides a curved member at the front end of the front-rear direction skeleton member, forms a wedge-shaped space portion between the curved member and the vehicle width direction skeleton member, and the curved member becomes a wedge-shaped space portion at the time of collision. Japanese Patent Application No. 2003-59016 discloses a vehicle body front part structure that can disperse while collapsing so as to increase the contact area between the curved member and the skeleton member in the vehicle width direction and efficiently disperse the collision load. And Japanese Patent Application No. 2003-59023.
JP 2002-356179 A (page 3, FIG. 4)

  However, in the vehicle body front structure in which the wedge-shaped space is formed between the skeleton member in the vehicle width direction by the curved member, load concentration in the axial direction of the skeleton member in the front-rear direction is improved while increasing the load distribution efficiency at the time of a frontal collision. Even when a collision with a small lap rate can be avoided, it is possible to improve the transmission of the axial load to the longitudinal frame member, but the bending member is configured by providing one for the longitudinal frame member. Therefore, the number of wedge-shaped spaces is one for one front-rear direction skeleton member.

  However, in order to further increase the load distribution efficiency, it is desirable to provide more wedge-shaped space portions.

  Accordingly, the present invention provides a vehicle body front part structure in which a plurality of wedge-shaped spaces are provided in the vehicle front-rear direction so as to increase the efficiency of collision load dispersion.

A plurality of right-angle skeletal members are arranged on the front-rear direction skeleton members at a predetermined interval in the vehicle front-rear direction, and curved members provided corresponding to the respective right-angle skeleton members are arranged at right angles to the front-rear direction skeleton members. The main feature is that a plurality of wedge-shaped spaces formed between the curved members and the right-angle skeletal members are provided in the vehicle anteroposterior direction by coupling so as to be in contact with the front and rear side surfaces of the directional skeleton members. To do.

  According to the present invention, since a plurality of wedge-shaped space portions formed between the bending member and the right-angle skeleton member are arranged in the vehicle front-rear direction, each bending member is converted into a right-angle skeleton member by the input of a frontal collision load. When the wedge-shaped space formed between and collapses so as to collapse, the contact area with the right-angled skeletal member can be further expanded to increase the dispersion efficiency of the collision load. The collision energy can be absorbed more efficiently and reliably regardless of the size of the object.

Input from the members 20, 30 to the front side member 1 and the side frame 8.

  At this time, the center front bending member 20 falls and deforms so as to crush the first wedge-shaped space S1, and the contact area between the center front bending member 20 and the center cross member 6 is expanded by the collapse deformation.

  As the collision further progresses, the front side member 1 is crushed in the axial direction, and the center rear curved member 21 is deformed. The center rear curved member 21 similarly collapses the second wedge-shaped space S2. Due to the falling deformation, the contact area between the center rear bending member 21 and the center second cross member 12 is expanded by the falling deformation.

  On the other hand, the lower front bending member 30 collapses and deforms so as to crush the third wedge-shaped space S3, and the contact area between the lower front bending member 30 and the lower cross member 9 is expanded by the collapse deformation, and the collision further progresses. The side frame 8 is crushed in the axial direction, and the lower rear curved member 31 is deformed, and the lower rear curved member 31 is similarly deformed so as to collapse the fourth wedge-shaped space portion S4.

Therefore, the contact area can be further increased.

  For this reason, at the time of a frontal collision, the collision energy can be absorbed more efficiently and reliably regardless of the size of the collision object.

  Also, since the collision area collides with the collision object in such a state that the contact area at the time of the collision is further increased, the energy absorbing members of the other vehicle that is the collision object at the time of the collision do not mesh with each other, and the function is sufficiently It is possible to prevent the load at the time of collision from concentrating on the front side member 1 even in a situation where it is not exhibited.

  Further, by providing a plurality of wedge-shaped spaces S1 to S4 in the vehicle front-rear direction as described above, the skeleton members at the front of the vehicle body such as the front side member 1, the side frame 8, the center cross member 6, and the lower cross member 9 are provided.

The wedge-shaped space portions S2 and S4 formed between the members and the rear curved members 21 and 31 can be provided in the middle portion of the front side member 1 and the side frame 8, and are not limited to the frontal collision. Even in the event of a diagonally forward collision in which a load is input to the front side of the vehicle body, the deformation of the curved members 21 and 31 progresses while the contact area is enlarged by the wedge-shaped space portions S2 and S4, so that energy absorption performance is improved. be able to.
