Adopt aforementioned technical scheme the utility model discloses, set up the longeron middle section through the slant, make threshold inner panel, longeron middle section and threshold support piece constitute the triangle-shaped structure, when the car takes place the side and bumps, the power that automobile threshold received transmits to the longeron middle section through the both ends comparison decentralization in longeron middle section, compares when the car takes place the side and bumps among the prior art, and the power that automobile threshold received is concentrated transmission to the longeron middle section more for the easy atress of longeron middle section warp problem, the utility model discloses when effectively having guaranteed that the car takes place the side and bumps, longeron middle section atress dispersion, non-deformable has strengthened the side collision performance of car.
Furthermore, the threshold support piece comprises a first support piece and a second support piece, the first support piece is arranged on the inner side of the threshold inner plate in a clinging mode along the longitudinal direction, the second support piece is arranged between the middle section of the longitudinal beam and the first support piece along the transverse direction, the threshold support piece is L-shaped or T-shaped, the contact area between the threshold support piece and the threshold inner plate is large due to the arrangement, and the side collision force can be dispersed conveniently.
Furthermore, the cross section of the first supporting piece is in a U shape with a downward opening, a cavity along the longitudinal direction is formed between the cross section of the first supporting piece and the front floor, and the first supporting piece has high rigidity and strength.
Furthermore, the cross section of the second supporting piece is in a shape like a Chinese character 'ji', a cavity along the transverse direction is formed between the second supporting piece and the front floor, and the second supporting piece has high rigidity and strength.
Furthermore, the included angle between the middle section of the longitudinal beam and the inner plate of the threshold ranges from 10 degrees to 30 degrees.
Furthermore, a plurality of lightening holes are formed in the first supporting piece or the second supporting piece, and therefore the automobile is light in weight.
For realizing the second purpose, the utility model adopts the following technical scheme:
an automobile includes the above front floor side reinforcing structure.
Compared with the prior art, the beneficial effects of the utility model are that: the middle section of the longitudinal beam is effectively guaranteed to be stressed dispersedly and not easy to deform when the automobile is subjected to side collision, and the side collision performance of the automobile is enhanced; meanwhile, the triangular structure formed by the inner sill plate, the middle section of the longitudinal beam and the sill support has better self rigidity, strength and stability, so that the side collision performance of the automobile is further enhanced; the automobile has the same technical effects as the aforementioned front floor side reinforcing structure.
