To describe technology contents of the present utility model, construction feature, the objects and the effects in detail, below in conjunction with implementation
Mode simultaneously coordinates accompanying drawing to be explained in detail.
Referring to Fig. 2, in the present embodiment, aldray refers to using aluminium as basic element and using magnesium, silicon to be main
The deforming alloy of alloying element.Belong to 6 line aluminium alloys, hot formability is good, moderate strength, good solderability and corrosion resistance.Tool
The technical scheme of body is as follows：
A kind of automobile door sill, automobile door sill are aldray material, and the automobile door sill is integrally formed；The car door
Sill include：Inner panel 1 and outside plate 2, the inner panel 1 are surface plate, and the outside plate 2 bends to be provided with the first bending section 3 and second
The curved slab in portion 4, first bending section 3 is different from the direction of the second bending section 4, the indent of the first bending section 3, wherein
First bending section 3 is to inner panel direction indent, the evagination of the second bending section 4, between the inner panel 1 and the outside plate 2 successively
Parallel interval is provided with the first buttress brace 5, the second buttress brace 6, the 3rd buttress brace 7 and the 4th buttress brace 8；First buttress brace
5 one end connect the top of inner panel 1, and the other end of the first buttress brace 5 connects the top of outside plate 2, second buttress brace 6
One end connects the inner panel 1, and the other end of the second buttress brace 6 connects the first bending section 3 of the outside plate 2, and the described 3rd adds
The one end of brutal 7 connects the inner panel 1, and the other end of the 3rd buttress brace 7 connects the lower section of the second bending section 4 of the outside plate 2, institute
To state the one end of the 4th buttress brace 8 and connect the bottom of inner panel 1, the other end of the 4th buttress brace 8 connects the outside plate 2, and described the
Four buttress braces 8 and the junction angle of outside plate 2 are 95 degree, are vertically set between the 3rd buttress brace 7 and the 4th buttress brace 8
It is equipped with the 5th buttress brace 9 and the 6th buttress brace 10, parallel 6th buttress brace 10 of the 5th buttress brace 9, the slender acanthopanax
Brutal 9 is arranged at the 4th buttress brace 1/8th three, and the 6th buttress brace 10 is arranged on the 4th buttress brace 8 three
At/bis-；The automobile door sill also includes：Lower side panel 11, described one end of lower side panel 11 connects the 4th buttress brace 8, described
The other end of lower side panel 11 connects the outside plate 2.
Further, the automobile door sill thickness is 2.5mm.
Further, the angle of the first bending section 3 is 105 degree, and the radian of the second bending section 4 is 110 degree.
Further, second buttress brace 6 is arranged on the length 11 of the inner panel 1/everywhere, and the described 3rd strengthens
Beam 7 is arranged at the length 8/11sts of inner panel 1.
As shown in Fig. 2 in the present embodiment, the automobile door sill selects high-strength aluminium-magnesium silico-aluminum, light (proportion
For 2.7), by extrusion process one-shot forming into required section bar, inner panel 1, outside plate 2, lower side panel 11 and buttress brace are designed to
One monolithic extruded realization, manufacturing process flow is enormously simplify, save processing cost.6 series alloys selected have good
Formability well, weldability, machinable, while there is preferable intensity, suitable for being wanted to corrosion resistance, oxidisability
High application is asked, meets the performance requirement of threshold.Traditional steel are replaced using light aluminum alloy materials in addition, are greatly reduced
The weight of automobile door sill, so as to improve the dynamic property of automobile, fuel consumption is reduced, while improve environment.
When the automobile door sill is by side impact, the stress of outside plate 2, acted on by the transmission of power, a part passes through rum point
Power is transferred to former and later two directions of beam along car body, and car column until whole car body, the impact transmission of another part part
To the first buttress brace 5, the second buttress brace 6, the 3rd buttress brace 7, the 4th buttress brace 8, the 5th buttress brace 9 and the 6th buttress brace 10
On, the 3rd buttress brace 7, the 4th buttress brace 8, the 5th buttress brace 9 and the 6th buttress brace 10 absorb part power, and its direction of transfer occurs
Change former and later two directions to beam along car body, reduce the 1 aduncate possibility of inner panel of threshold.It is complete to collide Path of Force Transfer
It is whole and corresponding construction part fully deformed energy-absorbing can be guided, so as to reduce side impact intrusion volume and invade the purpose of speed, improve
The safety coefficient of occupant during vehicle side impact.And the 4th buttress brace 8 is 95 degree with the junction angle of outside plate 2.So
Angle design, make threshold outer panel guide the transmission of side impact force to carry out downwards along the angled inward slant of vertical plane,
Small angle adjustment is unlikely to make threshold exterior bottom excessively prominent, and suitable vehicle is installed and used.
Further, the automobile door sill thickness is 2.5mm.Ensure that it has preferable rigidity and intensity, closer to commonly
The performance of threshold steel, meet threshold performance requirement.
Further, the angle of the first bending section 3 is 105 degree, and the radian of the second bending section 4 is 110 degree.Such arc
On the one hand the design of degree makes threshold attractive in appearance；On the other hand, bending curve position is the design of gradient at stress concentration in side impact
It can be very good energy-absorbing and change be allowed to more effective directed force by power path and transmitted downwards, play preferable energy-absorbing and make with buffering
With.
Further, second buttress brace 6 is arranged on the length 11 of the inner panel 1/everywhere, and the described 3rd strengthens
Beam 7 is arranged at the length 8/11sts of inner panel 1.By buttress brace position equalization setting, whole threshold internal structure system
One, in the absence of the weaker phenomenon of local location structure.In addition, the rigidity of the series alloys is lower slightly compared with high-strength steel.Door in side collision
Sill part is the important bang path of side impact force, and its rigidity has a major impact to the collision performance of car body, with the reduction of rigidity, B
Post intrusion speed is on a declining curve.So the rigidity for part of suitably lowering the threshold, increases B posts lower deformation, the deformation speed on top
Degree is reduced, and such result is advantageous to improve the Impact Resisting Capability of vehicle.
