For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
According to an aspect of the utility model embodiment, provide a kind of vehicle doorsill girder assembly, as depicted in figs. 1 and 2, comprising:
The sill strip 1 be fixedly connected with the floor threshold side bar of automobile, described sill strip 1 is by upper surface 101, the cavity structure that lower surface 102 and the middle interconnecting piece 103 connecting described upper surface 101 and described lower surface 102 are formed, described middle interconnecting piece 103 is provided with multiple arcuate structure 104 to lateral buckling in described cavity structure, and described sill strip 1 comprises A post connecting portion 105, B post connecting portion 106 and C post connecting portion 107, and the thickness of A post connecting portion 105 is greater than the thickness of B post connecting portion 106, the thickness of B post connecting portion 106 is greater than the thickness of C post connecting portion 107, and
Multiple sill strip support 2, described sill strip support 2 is fixedly connected on described sill strip 1, and is positioned at described cavity structure.
The vehicle doorsill girder assembly of the utility model embodiment, its sill strip 1 is the cavity structure be made up of upper surface 101, lower surface 102 and the middle interconnecting piece 103 that connects upper surface 101 and lower surface 102, this cavity structure can in analog-U shaped structure as shown in Figure 2, and according to structure design and stressing conditions, the middle interconnecting piece 103 of this cavity structure is offered multiple arcuate structure 104 to lateral buckling in cavity structure, the impulsive force that sill strip 1 is born can effectively be disperseed.
Wherein, this sill strip 1 can adopt flow forming production technology, compares the part that tradition is shaping, flow forming process can improve the stock utilization of part, reduces cost of parts, realizes the shaping of high performance material, thus improve the strength and stiffness of part, promote the side impact safety performance of car load.
In addition, according to the stressed difference of collision, sill strip 1 is designed to three sections of different-thickness, as shown in Figure 1: the Thickness Design of A post connecting portion 105 is T1, the Thickness Design of B post connecting portion 106 is the Thickness Design of T2, C post connecting portion 107 is T3, wherein, T1 > T2 > T3, effectively can alleviate the weight of the vehicle doorsill girder assembly of the utility model embodiment.Certainly, for the sill strip 1 at different parts with different-thickness, by not uniform thickness continuous rolling technology acquisition.
Wherein, multiple sill strip supports 2 that sill strip 1 is fixedly connected with, the application force that sill strip 1 can be subject to effectively passes to the miscellaneous part of automobile, adds the ability that the counter-bending of sill strip 1 is burst with resistance to compression, further ensures the form of distortion that sill strip 1 keeps good in side impact.In addition, this sill strip support 2 can adopt Hi-Stren steel to pass through progressive die punch forming.
Preferably, the quantity of described sill strip support 2 is three, and three described sill strip supports 2 are fixedly connected on and seat front cross rail respectively, on the sill strip 1 of seat after cross member and connecting panel corresponding position, floor, front and back, the application force that sill strip 1 is born can effectively pass to seat front cross rail by sill strip support 2, seat after cross member, floor, front and back connecting panel, thus reduce each parts by force intensity, the structural failure that when preventing single-piece stressed, part conquassation brings, reduce the deflection of side wall assembly during collision, to ensure the integraty of crew module, protection occupant preserves from.
Certainly, be understandable that, for concrete number and the installation site of sill strip support 2, be not limited thereto.
Preferably, mode is fixedly connected with for sill strip support 2 and sill strip 1, can be as shown in Figure 3 and Figure 4.Wherein, sill strip support 2 comprises the first connecting portion 201, second connecting portion 202 and the 3rd connecting portion 203, and described first connecting portion 201 is welded to connect with the upper surface 101 of described sill strip 1, the bonding connection of middle interconnecting piece 103 of described second connecting portion 202 and described sill strip 1, described 3rd connecting portion 203 is welded to connect on the lower surface 102 of described sill strip 1.Certainly, be understandable that, sill strip support 2 is not limited thereto with the mode that is fixedly connected with of sill strip 1.
In addition, be welded to connect because the second connecting portion 202 is inconvenient to adopt with the middle interconnecting piece 103 of sill strip 1, thus carry out adhesion by structural adhesion.Wherein, between the second connecting portion 202 and middle interconnecting piece 103, the size of area of contact determines the size (area of contact is larger, and the impulsive force that during collision, sill strip support 2 unit area is born is less) of the impulsive force that sill strip support 2 bears.Therefore, in order to can effective disperses impact forces, therefore the sill strip support 2 of Double-contact surfaces be designed at the middle part of sill strip 1.
Namely as shown in Figure 5 and Figure 6, the second connecting portion 202 with the sill strip support 2 of seat front cross rail and seat after cross member corresponding position, includes a contact surface fitted with the inner side of described cavity structure; The second connecting portion 202 with the sill strip support 2 of connecting panel corresponding position, floor, front and back, comprises two contact surfaces fitted with the inner side of described cavity structure.
In another embodiment of the present utility model, as shown in Figure 1, described vehicle doorsill girder assembly also comprises multiple brace panel 3, described brace panel 3 and described sill strip support 2 one_to_one corresponding, and described brace panel 3 is fixedly connected between described sill strip support 2 and the lower surface 102 of described sill strip 1.Because brace panel 3 area of thrust surface are large, therefore, effectively the impulsive force that sill strip support 2 bears can be disperseed by brace panel 3, prevent local pressure excessive.
In another embodiment of the present utility model, on the lower surface 102 of described sill strip 1, compartment of terrain is provided with multiple outage 4 along its length, makes the vehicle doorsill girder assembly of the utility model embodiment, in coating process, can ensure that liquid flows out, avoid the quality problems such as panel beating corrosion.Certainly, correspondingly, described brace panel 3 is provided with a through hole 5, and described through hole 5 communicates with outage described in one 4, avoids and forms closed inner chamber structure and be unfavorable for the discharge of liquid.
