Description
Technical field
The utility model belongs to automotive body structure, is specifically related to a kind of automobile door sill beam assembly structure.
Background technology
Vehicle doorsill girder assembly is one of main connection structure in gusset and floor, comparatively large to the Accuracy of car load assembling, requires that the precision of part own is higher.Simultaneously as the strength member resisting car body distortion during auto against, when vehicle generation head-on crash, sill strip assembly can keep the integraty of occupant space, effectively transmits impact force, therefore requires that sill strip has enough counter-bending and that resistance to compression is routed ability in car body X-direction; In side impact, also require the form of distortion that sill strip keeps good, ensure that side impact force is disperseed effectively to floor and crossbeam.But the quality problems such as in vehicle, most of sill strip part is irregular because of section form at present, limits, adopt cold punching technology more during production by project organization, and this part uses Sheet Metal Forming Technology easily resilience to occur, curling.The attainable strength of material of cold stamping part is lower simultaneously, and the strength and stiffness of sill strip structure are lower, produces undercapacity when colliding, and produces the failure modes such as distortion, conquassation.And there is the defects such as perishable, impeded drainage in coating process; There are the quality problems such as panel beating corrosion after the listing of some vehicle.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile door sill beam assembly structure, with the collision performance of the bending-twisting ability and side direction that improve vehicle body.
Automobile door sill beam assembly structure described in the utility model, comprise the sill strip be connected with floor threshold side bar, the sill strip leading portion be connected with sill strip and gusset A-pillar and machinery space, and the sill strip back segment to be connected with sill strip and rear-wheel hub bag, the section of described sill strip and floor threshold side bar all takes the shape of the letter U, and sill strip and floor threshold side bar is upper, lower landing edge is welded to each other formation cavity structure, also comprise the threshold reinforcement that three structures are identical, three threshold reinforcements are welded on and seat front cross rail respectively, on the sill strip of seat after cross member and connecting panel corresponding position, floor, front and back, and three threshold reinforcements are all positioned at cavity structure.When vehicle generation side collision; the power that sill strip bears can effectively pass to seat front cross rail, seat after cross member, floor, front and back connecting panel by threshold reinforcement; by the transmission of power; what reduce each parts is subject to force intensity; the structural failure that when preventing single-piece stressed, part conquassation brings; reduce the deflection of side wall assembly during collision, to protect the integraty of crew module, protection occupant preserves from.
Further, the line of centers of three described threshold reinforcements overlaps at the line of centers one_to_one corresponding of vehicle body Y-direction with seat front cross rail, seat after cross member and floor, front and back connecting panel respectively.When vehicle generation side collision, more effectively the power that sill strip bears can be passed to seat front cross rail, seat after cross member and floor, front and back connecting panel by these three threshold reinforcements.
Described threshold reinforcement takes the shape of the letter U, and is respectively equipped with the first outside flange at the dual-side of threshold reinforcement, and described threshold reinforcement passes through the first flanging welded in the inner side of sill strip.Adopt U-shaped structure, two sides has flange to strengthen, and has 6 welding edges and welds with sill strip, strengthen doorsill structure, improves threshold intensity, promote side impact ability to reach.
The edge of the lower landing edge of described sill strip is provided with the second inside flange, and this second flange shelters from the gap between the lower landing edge of sill strip and floor threshold side bar.That liquid and foreign material in driving conditions can be avoided to invade sill strip and floor threshold side bar welds gap, prevents face of weld corrosion.
Further, the width of described second flange is 3 ~ 10mm.
The lower plane of described sill strip is interval with along its length 6 ~ 8 outages.In coating process, can ensure that liquid effectively flows out, avoid the quality problems such as panel beating corrosion.
The utility model has the following advantages:
(1) three threshold reinforcement is welded on respectively with on the sill strip of seat front cross rail, seat after cross member and connecting panel corresponding position, floor, front and back, and this structure substantially increases the bending-twisting ability of vehicle body and the collision performance of side direction.When vehicle generation side collision, the power that sill strip bears can effectively pass to seat front cross rail, seat after cross member, floor, front and back connecting panel by threshold reinforcement, by the transmission of power, what reduce each parts is subject to force intensity, the structural failure that when preventing single-piece stressed, part conquassation brings, reduce the deflection of side wall assembly during collision, thus reach the integraty of protection crew module, protection occupant preserves from;
(2) outage is set on the lower plane of sill strip, in coating process, can guarantees that liquid flows out effectively by outage, avoid the quality problems such as panel beating corrosion;
(3) edge of the lower landing edge of described sill strip is provided with the second inside flange, this second flange shelters from the gap between the lower landing edge of sill strip and floor threshold side bar, that liquid and foreign material in driving conditions can be avoided to invade sill strip and floor threshold side bar welds gap, prevents face of weld corrosion;
(4) sill strip is rule section, forming process can meet hydraulic expanding type, roll-forming, Heat forming, the kinds of processes requirement such as cold stamping shaped, to the forming process multiple choices of part, compare the part that tradition is shaping, new 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.
