Abstract
The utility model provides an automobile doorsill beam which comprises an inside plate of the doorsill beam, an outside plate of the doorsill beam and a reinforcing plate assembly arranged between the outside plate and the inside plate of the doorsill, wherein the reinforcing plate assembly is provided with a cavity beam structure and is fixedly installed on the outside plate of the doorsill beam along the longitudinal direction by spanning a front door and a rear door. By adopting the cavity beam structure, the automobile doorsill beam can effectively decrease in-breaking extent and protect passengers from accident to the greatest extent when an automobile meets with a high-speed lateral crash.
Description
Technical field
The utility model relates to the arrangements for automotive doors parts, relates in particular to the automobile door sill beam.
Background technology
Along with the development of society, people more and more pay attention to the safety problem of automobile, require it can bear strict central collision, side impact, and chaufeur and occupant's safety is guaranteed.
Fig. 1 is the structural representation of Vehicular side body in the prior art.In Fig. 1, the 11st, B post, the 12nd, sill strip, the 13rd, side-wall outer-plate, sill strip 12 is made up of the fagging of doorframe beam outside plate, doorframe beam inner panel and localized design.When automobile side impact, sill strip 12 receives from B post 11 and transmits the energy of coming.These energy are by being delivered to the opposite side of body framwork with sill strip bonded assembly floor crossmember (not shown), thereby are attenuated and absorb, and have avoided that the car cabin is inner, and bigger distortion takes place, and have protected the occupant.
Yet when automobile side arrived high-speed impact, especially the speed when side collision was bigger, side is hit direction when becoming certain acute angle with vehicle body, and sill strip can directly be subjected to a greater impact load input, in the real vehicle experiment, most sill strip distortion are excessive, even fracture.The direct result of bending fracture is that the distance that collision body is invaded the crew module is big, directly injures the occupant; Secondly because the bending of the part of sill strip has influenced collision energy and has been delivered to timely and effectively on the floor crossmember by sill strip, produce the injury that adds up.
Therefore, in order to improve the ability of bearing side impact, traditional solution is the material thickness that increases sill strip, adopt high-intensity steel plate, but resulting actual effect is unsatisfactory.
The utility model content
The utility model proposes in view of problems of the prior art just; its objective is provides a kind of improvement automobile door sill beam; when vehicle generation high-speed side is hit (be primarily aimed at angled side hit hit) with the side post, can effectively reduce the intrusion amount, farthest protect occupant safety.
The technical solution of the utility model is as follows: a kind of automobile door sill beam, comprise sill strip inner panel, sill strip outside plate and be arranged on brace panel assembly between sill strip inner panel and the outside plate, wherein, described brace panel assembly has the cavity girder construction, and longitudinally is fixedly mounted on the sill strip outside plate in the mode of crossing over Qianmen and back door.
As further improvement of the utility model, the brace panel assembly comprises: column brace panel, the cross-sectional plane of column brace panel are the U font structures that is made of three sidewalls, the axial open at both ends of described column brace panel.Preferably, described brace panel assembly also comprises two end-plates, is fixed on the brace panel both ends, and the U font open side of column brace panel is faced mutually and is fixed on the sill strip outside plate with the sill strip outside plate, thereby forms the osed top cavity body structure with the sill strip outside plate.
As further improvement of the utility model, on one of them person in other three lateral column walls of column brace panel, a plurality of perforates have been provided at predetermined intervals.
Preferably, the column brace panel is selected Martensitic steel for use, and the rear and front end shrouding is selected CR340 for use.
Preferably, be provided with the stay bearing plate that parallels with two end-plates in column brace panel inside.
In sum; the utility model has the advantages that: simple in structure; with low cost; utilize the enclosed cavity beam to have superpower resistance to bending, from the Qianmen to the back door, design a kind of bus organization, form the sealed hollow girder construction with the sill strip outside plate; by improving the rigidity and the intensity of sill strip regional area; thereby reduce the distortion of sill strip, effectively transmit collision energy, protect the occupant in the time of can being implemented in automobile generation side impact to greatest extent.

The specific embodiment
Preferred implementation to automobile door sill beam described in the utility model describes below.
One embodiment of bus type column brace panel assembly described in the utility model is described in conjunction with Fig. 2, Fig. 3.
The automobile door sill beam comprises sill strip inner panel, sill strip outside plate and is arranged on brace panel assembly 20 between sill strip inner panel and the outside plate.Wherein, sill strip inner panel, sill strip outside plate are known, do not describe at this.Described brace panel assembly 20 comprises: column brace panel 21, the cross-sectional plane of described column brace panel 21 are " U " font, have three sides to have post jamb, and opposite side is open, and axial open at both ends; Preferably can also comprise two end-plates 22,23 that the column brace panel is axial, be fixed on described brace panel 21 both ends by welding manner.
As shown in Figure 4, when concrete assembling, owing to bus type column brace panel assembly 20 is made up of column brace panel 21, rear and front end shrouding 22,23, so, at first be welded into branch unit by these three parts; Then, the sidewall opening side of the described column brace panel 21 in this branch unit is faced mutually with the sill strip outside plate, is fixed by welding on the described sill strip outside plate, thereby forms the osed top cavity body structure with the sill strip outside plate, promptly forms sill strip outside plate assembly; Then sill strip outside plate assembly is welded into side wall assembly with parts such as B post, gussets again.
The utility model utilizes the sealed hollow beam to have superpower resistance to bending.From the Qianmen to the back door, constitute bus organization, thereby form the sealed hollow girder construction with the sill strip outside plate.By improving the rigidity and the intensity of sill strip regional area, when automobile generation side impact, can reduce the distortion of sill strip, realize that collision energy effectively transmits, protect the occupant to greatest extent.
In addition, when making bus type column brace panel assembly 20, can in assembly, weld one or more stay bearing plates (not shown), further improve the rigidity and the intensity of sill strip regional area according to actual conditions.
In addition, on one of them person in other three lateral column walls of column brace panel 21, be provided with a plurality of perforates in the mode that keeps set interval, thereby can alleviate car body weight.
In addition, in the above-described embodiment, aspect the material selection, the preferred Martensitic steel of column brace panel, the preferred CR340 of rear and front end shrouding.By adopting this material structure, the distortion of the side in sill strip zone reduces significantly, can be more effectively and transmit energy in time, and the distortion that reduces the crew module is with the protection occupant.
The utility model is not limited to above-mentioned column brace panel assembly; being equally applicable to cross-sectional plane is the brace panel assembly of cylindrical or other shape; as long as longitudinally being fixedly mounted on the above brace panel assembly of sill strip outer plate surfaces has the cavity girder construction, belong to protection domain of the present utility model too.
