The invention provides a floor longitudinal beam reinforcer, a floor longitudinal beam structure and a vehicle. The floor longitudinal beam reinforcer comprises a first tubular beam, a second tubularbeam, an outer baffle plate, an inner baffle plate and a double-tube baffle plate, the inner baffle plate is provided with an open pore for the second tubular beam to pass through, and the outer baffle plate is provided with an open pore for the first tubular beam to pass through; a first hole and a second hole are formed in the double-tube baffle plate, the first tubular beam penetrates through the outer baffle plate, one end of the first tubular beam is connected with the first hole of the double-tube baffle plate, the second tubular beam penetrates through the inner baffle plate, and one end of the second tubular beam is connected with the second hole of the double-tube baffle plate. According to the invention, the problems that a direct force transmission path is lacked at the bottom of an existing product in side collision, and a battery shell is greatly deformed due to impact force are solved; the the floor longitudinal beam reinforcer, the floor longitudinal beam structure and the vehicle have the advantages of being high in strength of a side impact area, capable of effectively dispersing impact force and small in deformation degree in the impact process.

    本发明提供一种地板纵梁加强件、地板纵梁结构以及车辆,其中,地板纵梁加强件包括:第一管梁、第二管梁、外挡板、内挡板和双管挡板,内挡板上设置有可供第二管梁穿过的开孔,外挡板上设置有可供第一管梁穿过的开孔,双管挡板上设置有第一开孔和第二开孔,第一管梁穿过外挡板,其中一端与双管挡板的第一开孔连接,第二管梁穿过内挡板,其中一端与双管挡板的第二开孔连接。通过本发明的地板纵梁加强件、地板纵梁结构以及车辆,解决了现有产品在侧面碰撞中底部缺少直接的传力路径、撞击力会使电池壳体产生较大形变的问题,具有侧面受撞击区域强度高、可将撞击力有效分散、撞击过程中变形程度较小的优点。
