The utility model content
The utility model be for the automobile door sill reinforced support overall construction intensity that solves prior art poor, thereby want a plurality of the setting respectively to form local single-piece reinforcement on the threshold inner panel, can not effectively guide transmission and the dispersion of side impact force during side impact, can not play good support reinforcing effect to threshold, be unfavorable for simultaneously the welding of real vehicle and the problem of location, provide a kind of simple in structure, overall construction intensity is high, can greatly improve the automobile door sill reinforced support of threshold side impact performance.
To achieve these goals, the utility model is by the following technical solutions:
A kind of automobile door sill reinforced support, comprise stay bearing plate and energy-absorbing crossbeam, be arranged at intervals with some reinforced holes on the described energy-absorbing crossbeam, the front edge of described energy-absorbing crossbeam is provided with downward connecting panel, the free end of described connecting panel is provided with outside reinforcement flange, described stay bearing plate is fixedly connected on energy-absorbing crossbeam both sides and consists of " U " shape structure with the energy-absorbing crossbeam, and the edge of stay bearing plate is equipped with outside connection flange.Be arranged at intervals with some reinforced holes on the energy-absorbing crossbeam, the energy-absorbing crossbeam is used for directly bearing the impulsive force that side collision brings when collision, to reduce the deformation quantity of automobile door sill, reinforced hole then can effectively guide and disperse side impact force, make the energy-absorbing crossbeam be difficult for occuring deformation, improve the crush resistance of energy-absorbing crossbeam, stay bearing plate is positioned at the mounting groove on the automobile door sill and fits with automobile door sill, play spacing effect, can prevent effectively again simultaneously that unstability occured the vertical direction at threshold when whole reinforced support was subject to side impact, crumple, improve the structural strength and stability of whole reinforced support, the connection flange that is arranged on the support plate edge outside is used for welding with automobile door sill, whole reinforced support is fixed on the automobile door sill, connecting panel plays transitional function, is used for connection reinforcement flange and energy-absorbing crossbeam, strengthens flange and is used for welding with automobile doorsill reinforcing plate, increase the contact surface of reinforced support and threshold brace panel, improve the resistance to overturning of support.
As preferably, described stay bearing plate is provided with auxiliary hole.
As preferably, described energy-absorbing crossbeam, connecting panel, stay bearing plate, connection flange and strengthen flange and be structure as a whole.Integrative-structure is simple, and is easily manufactured, and productive costs is low, and integrative-structure is conducive to welding and the location of real vehicle.
As preferably, described energy-absorbing crossbeam is the bar shaped platy structure.
As preferably, be arranged at intervals with some reinforcement grooves on the described reinforcement flange.Strengthen groove and can improve the ability of anti-deformation of strengthening flange, strengthen the structural strength of whole reinforced support.
As preferably, the reinforcement flange between the adjacent reinforcement groove is provided with breach.Breach can further guide and disperse side impact force, has further improved the ability of anti-deformation of whole reinforced support.
As preferably, the edge of described reinforced hole is recessed to form ledge structure downwards.Ledge structure plays the effect of reinforced rib, so that reinforced hole is difficult for occuring deformation, crumple, improves structural strength and stability.
As preferably, described reinforced hole is bar hole.The anti-deformation of bar hole and conquassation ability are strong, guiding and disperse the effective of side impact force.
Therefore, the utlity model has following beneficial effect:
(1) overall construction intensity is high, good stability;
(2) can effectively guide and disperse side impact force, anti-deformation and conquassation ability are strong, can greatly improve the side impact performance of automobile door sill;
