Specific embodiment

Fig. 1 is the longitudinal beam front section outside plate front view of the utility model, and Fig. 2 is the longitudinal beam front section outside plate side of the utility model Structural schematic diagram, a kind of longitudinal beam front section outside plate, including outside plate 2 after the crumple plate 1 being fixedly connected along longitudinal direction and stringer, the crumple It is fixedly installed in the lateral surface of longitudinal beam front section after outside plate 2 is fixed after plate 1 and stringer, is indulged in the technical program by traditional integral type Beam leading portion outside plate changes into segmented connection design, and when making automobile impacting, longitudinal beam front section outside plate can be according to preset crumple side Formula carries out, and is controlled better its crumple, improves automobile and the safety of driver.

In the present embodiment, 2 outward bending of outside plate forms the first bending side after the stringer, and to form second curved bending downward Folding face, the second bending, which faces out, to be arched upward and is formed and bulge-structure, after stringer outside plate 2 to formed after bending on the outside of stringer one compared with Small bending side is bent to form second bending side parallel with stringer then to lower for the second time, and the second bending side is along stringer It arches upward outward (along tire axial outwardly direction), is convenient to the installation of outside plate 2 and stringer after stringer, while the second bending side Curved design, also more conducively car crass when absorb energy and according to specified direction crumple.

In the present embodiment, outside plate 2 second bending side is provided with a plurality of raise upward after the stringer on along the longitudinal direction Waling 5, the reinforcing rib 5 of longitudinal design can effectively improve the stiffness and strength of outside plate 2 after stringer, make outside plate 2 after stringer With better security performance.

In the present embodiment, after the stringer 2 second bending side of outside plate in transverse direction on be additionally provided with it is a plurality of laterally reinforce Muscle 6, cross reinforcing 6 can effectively solve the problem that the problems in the stress collection that the second bending side bulge-structure is formed, while pass through cross Mutual cooperation to reinforcing rib 6 and waling 5, when stringer after outside plate 2 there is higher stiffness and strength, improve outer after stringer The service life of plate 2.

In the present embodiment, after the stringer end of 2 second bending side of outside plate bend inwards and with outside plate, first after stringer Bending side, which is enclosed spiral-lock, can make stringer by fastening the location and installation of installation groove in the fastening installation groove of stringer Leading portion outside plate reduces installation error during installation, saves the set-up time, effectively improves assembly efficiency.

In the present embodiment, 1 both ends of crumple plate are folded upward at, and crumple plate 1 is connected as one with outside plate 2 after stringer, are burst Contracting plate 1 connects section bending and is convenient to the connection setting of outside plate 2 after stringer, it is preferred that by welding, is more advantageous to crumple plate 1 Crumple is carried out along expected mode.

In the present embodiment, it is provided with the crumple muscle 4 of a plurality of protrusion on the crumple plate 1, is mutually put down between the crumple muscle 4 Row setting, crumple muscle 4 can design on the crumple plate 1 of finite length by the setting of parallel equidistant and meet crumple enough Distance, crumple muscle 4, which can also play, promotes crumple plate 1 to carry out crumple along the mode of expected setting.

In the present embodiment, the crumple hole 3 of ellipse is additionally provided on the crumple plate 1, crumple hole 3 is also acted as to crumple plate 1 carries out the effect of installation positioning, is more advantageous to the connection installation of outside plate 2 after crumple plate 1 and stringer.
