Abstract
The present invention proposes a kind of high strength doorsill structure, and by threshold inner panel, threshold brace panel, side-wall outer-plate and threshold trim board are formed.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, the threshold position of side-wall outer-plate is enclosed in the top and side of threshold brace panel, the upper overturning welding of top and threshold brace panel, fit and weld in following landing edge and threshold brace panel side.This structure is by the bottom of cancellation side-wall outer-plate doorsill structure, make the bottom welding edge in threshold brace panel middle part and its welding, and suitably enlarge the bottom section of threshold brace panel, improve the intensity of threshold, and produce inaesthetic problem owing to improve side-wall outer-plate in the bottom level of threshold part by using the threshold trim board to solve.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.
Description
Technical field
The invention belongs to the auto body technical field, be specifically related to a kind of doorsill structure of automobile.
Background technology
Referring to Fig. 1, traditional automobile door sill structure comprises threshold position 1 on the side-wall outer-plate, threshold brace panel 2, threshold inner panel 5 etc., and the three welds by flange up and down, and the centre surrounds two-layer cavity.Wherein side-wall outer-plate belongs to the large tracts of land profiled member, the doorsill structure complexity on the side-wall outer-plate, and processing belongs to deep drawn, and drawing crack, defective such as wrinkling often appear in insufficient formability, and the side-wall outer-plate material is thick thinner in punching course.Simultaneously, the cavity that forms between threshold brace panel 2 and the threshold inner panel 5 is big inadequately, adds that side-wall outer-plate itself is thinner, though its integral body all surrounds top, the side and bottom surface three faces of threshold brace panel 2, but the intensity of total still be cannot say for sure to demonstrate,prove, and also causes cost to increase.In addition, it is too much that there is the welding number of plies in whole doorsill structure.As flange up and down all is three layers of weldering form, has increased the welding difficulty, and welding quality is difficult to be guaranteed.Above problem all has influence on the in-use performance and the quality of whole doorsill structure.
The utility model content
At the deficiencies in the prior art, a kind of simple in structure, intensity increases to some extent and the high strength doorsill structure of motorcar of saving in material but the present invention proposes.
Technical solution of the present invention is as follows:
A kind of high strength doorsill structure of motorcar, 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 invention 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.

The specific embodiment
Describe structure of the present invention in detail below in conjunction with accompanying drawing:
Referring to Fig. 1 and Fig. 2, this doorsill structure is made up of the threshold position 1 and the threshold trim board 3 of threshold inner panel 5, threshold brace panel 2, side-wall outer-plate, and wherein the threshold trim board is a Plastic Parts, and all the other are sheet metal, and especially threshold brace panel 2 adopts high tensile steel plate.Threshold inner panel 5 and threshold brace panel 2 direction projection outside Che Nei and car respectively wherein, flange is welded to each other up and down, and the centre surrounds a nearly rectangular big cavity A.The threshold position 1 of side-wall outer-plate is enclosed in the top and side of threshold brace panel 2, the upper overturning welding of top and threshold brace panel 2, and following landing edge 11 is fitted with the middle part, side of threshold brace panel 2 and is welded.Be formed with the extended area B that further extends out in threshold brace panel side and the position below 11 welding of following landing edge,, improve threshold intensity to increase its cavity area.Threshold trim board 3 is wrapped on outside the threshold position 1 and threshold brace panel 2 of side-wall outer-plate, wrap that the threshold position of whole side-wall outer-plate and threshold brace panel expose to whole bottom surface, align with the weld, top at the threshold position of side-wall outer-plate in the upper edge, align with the following flange middle part of threshold brace panel in the lower edge, so more can fully cover in outside appreciiable weld, and by threshold position 1 locking of snap close 4 with side-wall outer-plate.
During installation, the threshold position 1 of side-wall outer-plate is gone out the applying welding with threshold brace panel 2 at following landing edge, again with the welding up and down of threshold inner panel 5, the threshold trim board 3 that snap close 4 will be housed then is installed in threshold brace panel 2 and threshold inner panel 5 and welds on the good side-wall outer-plate 1, and it is to link together by the threshold position 1 of snap close 4 with side-wall outer-plate.
