Abstract
The utility model aims at providing a low in production cost, efficient automobile threshold structure, including threshold inner panel and threshold reinforcing plate, the shape of threshold inner panel and threshold reinforcing plate the same, the whole U type trough form that is of threshold inner panel, notch department is provided with first external turn-ups, threshold inner panel and threshold reinforcing plate notch mutual disposition, the first external turn-ups of threshold inner panel and the second external turn-ups laminating of threshold reinforcing plate are connected as an organic whole. Among the above-mentioned scheme, when realizing threshold reinforcing plate and threshold inner panel general, it is general still to satisfy about, adopt the roll-in technique back, can make 4 original roll-in production lines reduce to 1 production line after the improvement, practiced thrift 3 factory building areas and the cost of labor of production line, because of the reduction of cost of labor reduction and factory building rent, promoted simple cost's reduction, again because of adopting 1 roll-in line to produce 4 pieces, efficiency also obtains improving, consequently, bicycle manufacturing cost obtains further reduction again.
Description
Technical Field
The utility model relates to an automobile body technical field, concretely relates to automobile threshold structure.
Background
The strength of the automobile doorsill structure, which is an important component of a body-in-white, is directly influenced by the deformation of a passenger compartment during a side collision, thereby influencing the side collision safety performance of the automobile. At present, the threshold structure mainly comprises threshold inner panel and threshold reinforcing plate, in order to satisfy security performance and side impact requirement, threshold reinforcing plate and threshold inner panel adopt the roll-in spare also more and more generally, the cross-section of threshold reinforcing plate and threshold inner panel is different, in addition threshold reinforcing plate and threshold inner panel all are bilateral symmetry spare, consequently need 4 roll-in production lines when producing, what the increase of production line must bring is the increase of disposable cost, and 4 roll-in production lines occupy production area also big, in car assembling process, in order to distinguish left side, right side threshold inner panel and left side, right side threshold reinforcing plate, prevent the mistake of loading, this can influence production efficiency to a certain extent.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a low in production cost, efficient automobile threshold structure.
In order to realize the purpose, the utility model discloses a technical scheme be: the utility model provides an automobile doorsill structure, includes doorsill inner panel and doorsill reinforcing plate, the shape of doorsill inner panel and doorsill reinforcing plate the same, the whole U type trough form that is of doorsill inner panel, notch department is provided with first external turn-ups, doorsill inner panel and doorsill reinforcing plate notch mutual disposition, the first external turn-ups of doorsill inner panel and the second external turn-ups laminating of doorsill reinforcing plate are connected as an organic whole.
Among the above-mentioned scheme, when realizing threshold reinforcing plate and threshold inner panel general, it is general still to satisfy about, adopt the roll-in technique back, can make 4 original roll-in production lines reduce to 1 production line after the improvement, practiced thrift 3 factory building areas and the cost of labor of production line, because of the reduction of cost of labor reduction and factory building rent, promoted simple cost's reduction, again because of adopting 1 roll-in line to produce 4 pieces, efficiency also obtains improving, consequently, bicycle manufacturing cost obtains further reduction again.

fig. 2 is a cross-sectional view of the sill structure.
Detailed Description
As shown in fig. 1 and 2, the automobile doorsill structure comprises a doorsill inner plate 10 and a doorsill reinforcing plate 20, wherein the shape of the doorsill inner plate 10 is the same as that of the doorsill reinforcing plate 20, the whole doorsill inner plate 10 is in a U-shaped groove shape, a first external flanging 11 is arranged at the position of a groove opening, the groove openings of the doorsill inner plate 10 and the doorsill reinforcing plate 20 are oppositely arranged, and the first external flanging 11 of the doorsill inner plate 10 and a second external flanging 21 of the doorsill reinforcing plate 20 are attached and connected into a whole. With threshold inner panel 10 and threshold reinforcing plate 20's shape design the same, when realizing that threshold reinforcing plate 20 and threshold inner panel 10 are general, still satisfy about general, adopt the roll-in technique back, can make 4 original roll-in production lines reduce to 1 production line after the improvement, 3 the factory building area and the cost of labor of production line have been practiced thrift, because of the reduction of cost of labor reduction and factory building rent, the reduction of simple cost has been promoted, because of adopting 1 roll-in line to produce 4 pieces again, efficiency also obtains improving, consequently, bicycle manufacturing cost obtains further reduction again.
In order to meet the requirements of safety performance and side impact, the inner threshold plate 10 and the reinforcing threshold plate 20 are arranged in a staggered mode in the length direction, and the first external flanging 11 and the second external flanging 21 are also arranged in a staggered mode in the width direction of the flanging, so that the structural strength is high.
Similarly, the distances from the two first external flanges 11 on the inner sill plate 10 to the groove bottom 13 are different, and the first external flanges 11 and the second external flanges 21 are eccentrically arranged relative to the central line of a cavity formed by the inner sill plate 10 and the reinforcing sill plate 20, so that the side impact performance of the sill is greatly improved.
In order to facilitate the connection of the rocker inner panel 10 and the rocker reinforcement panel 20, the first outboard bead 11 and the second outboard bead 21 are arranged in parallel.
Furthermore, the U-shaped notch of the inner sill plate 10 is in a flaring shape, the joint of the groove wall 12 and the first external flanging 11 is in fillet transition, and the joint of the groove wall 12 and the groove bottom 13 is also in fillet transition.
The groove bottom 13 is rolled with a reinforcing step 131 along the groove length direction, further improving the overall strength and side impact performance.
