The utility model content
At the deficiencies in the prior art, a kind of simple in structure, intensity increases to some extent and the automobile door sill structure of saving in material but the utility model proposes.
Technical solutions of the utility model are as follows:
A kind of automobile door sill structure, it comprises that weld together relies on threshold inner panel in the car, relies on the threshold position of the outer side-wall outer-plate of car, and be welded on above-mentioned threshold brace panel between the two, described threshold inner panel and threshold brace panel be direction projection outside Che Nei and car respectively, flange is welded to each other up and down, the centre surrounds a big cavity, and this spatial spread is bigger, is a nearly rectangular large space.The threshold position of described side-wall outer-plate only surrounds the top and side of threshold brace panel, the welding of the upper overturning of top and threshold brace panel, the welding of fitting of following landing edge and threshold brace panel side, and reasonable be to fit with the middle part of threshold brace panel side to weld.And, can also form the projection that further extends out in described threshold brace panel side and the position below the landing edge welding, play the effect in the space between further increase threshold inner panel and the threshold brace panel.
For the position of weld, threshold position that hides owing to side-wall outer-plate upwards promotes the weld that forms, outside the threshold position and threshold brace panel of described side-wall outer-plate, also wrapped a threshold trim board, described threshold trim board wraps the threshold position of whole side-wall outer-plate and the whole bottom surface that the threshold brace panel exposes, and preferably is connected with the threshold position of side-wall outer-plate by snap close.
Advantage of the present utility model is as follows:
1, this doorsill structure is by dwindling the cavity area of side-wall outer-plate threshold position and threshold brace panel, and increases the cavity area between threshold inner panel and the threshold brace panel, reaches the purpose that raising can be seen intensity.
2, that part bottom original parcel threshold brace panel on the cancellation side-wall outer-plate, the weld is risen to the medium position of threshold brace panel side, saved material, make simultaneously originally by the threshold inner panel, the threshold brace panel, three layers of weldering of side-wall outer-plate are decomposed, and become the two-layer weldering that side-wall outer-plate is followed the threshold inner panel with the two-layer weldering and the threshold brace panel of threshold brace panel, simplify welding process, improved the firm welding degree again.
3, do suitable extending out by the position below the landing edge on the threshold brace panel, further increase the cavity area between threshold brace panel and the threshold inner panel, because the thickness of threshold brace panel is the nearly twice of side-wall outer-plate, what adopt usually is high tensile steel plate, so the doorsill structure intensity after the cavity area increases is further enhanced.
4, adopt the threshold trim board that the weld is hidden; solved owing to improving the bottom level of side-wall outer-plate and produced inaesthetic problem in the threshold part; guaranteed that the threshold overall appearance is unaffected, and thin side-wall outer-plate has been played certain protective role.
Generally speaking, this designs simplification the Sheet Metal Forming Technology and the welding process of side-wall outer-plate, improved the intensity of threshold, reduced cost, and satisfied the weight-saving principle of design.
