Abstract
The side collision-resisting strengthening structure for automobile includes one back floor front crossbeam, one back floor strengthening beam, one front threshold board and one force guiding strengthener welded together to form one cavity. During side collision, the side collision force may be dispersed through the side collision-resisting strengthening structure to the strengthening beam structure on the floor effectively.
Description
Technical field
The present invention relates to the automotive body structure technology.
Background technology
In self-supporting body, the floor front cross rail is not only wanted the load of a bearing vehicle body part and various total piece installings is installed behind the car body, even also will play the effect of strengthening the floor in side impact, and then protection occupant's living space, reduces the injury of side impact to personnel.The back floor front cross rail of present most of car and the bridging arrangement of peripheral part mainly are to consider to conduct side impact force to the front cross rail of floor, back by gusset threshold reinforcement.After certain distortion took place on the floor, side impact force just can be transmitted on the beam structure like this, was not very timely to the reinforcement of floor deformation.
Summary of the invention
The objective of the invention is to deficiency, propose a kind of automobile rear floor side impact additional strengthening, utilize the dependency structure on the floor, increase some reinforcements and make it to lead the power beam structure with front cross rail composition floor, floor, back at the prior art existence.Like this in car body side impact process, side impact force can be distributed on the strength beam structure on the floor effectively, thereby disperses side impact force effectively, improves the floor side collision strength.
Technical scheme of the present invention is as follows:
Floor front cross rail, back-floor reinforcement beam, front door sill inner panel and lead the power reinforcement behind this automobile rear floor side impact additional strengthening, the front end of back floor front cross rail and the front end of back-floor reinforcement beam one side transverse lap, back-floor reinforcement beam front end opposite side and front door sill inner panel vertically weld, inboard that the back-floor reinforcement beam front end overlaps with floor front cross rail position of weld, back and and the front door sill inner panel between be welded with and lead the power reinforcement, make preceding floor front cross rail, back-floor reinforcement beam, lead the power reinforcement and the front door sill inner panel forms a cavity in welding region.
Further, on the front door sill inner panel with welding lead the relative opposite side of power reinforcement weld again one with the auxiliary reinforcement of leading power reinforcement direction unanimity.
Structure of the present invention is on the basis of present floor, existing back front cross rail, by the corresponding reinforcement of increase in the space between crossbeam and threshold side bar, makes that itself and crossbeam are stressed to be communicated with.When car body suffered Ce Touch, gusset central post reinforcement can be transmitted to power by threshold and lead on the power reinforcement, and led the power reinforcement owing to overlap with the floor crossmember face of weld, so the suffered side impact force in floor can be distributed on the floor.This structure can increase floor De Ce Touch intensity, reduces floor local deformation amount, reduces the intrusion amount of central post, guarantees occupant's living space, thereby improves the safety factor of vehicle body in side impact, and the occupant is played a very good protection.
Description of drawings
Fig. 1 is this automobile rear floor side impact additional strengthening scheme drawing.
Fig. 2 is floor, back front cross rail, back-floor reinforcement beam and the assembling exploded view of leading the power reinforcement.
Fig. 3 is auxiliary reinforcement and front door sill inner panel assembling exploded view.
The specific embodiment
As shown in Figure 1, this side impact additional strengthening by back floor front cross rail 1, back-floor reinforcement beam 2, front door sill inner panel 4, lead power reinforcement 3 and auxiliary reinforcement 5 constitutes.The front end of back floor front cross rail 1 and the front end of back-floor reinforcement beam 2 a side transverse lap, back-floor reinforcement beam 1 front end opposite side and front door sill inner panel 4 vertically weld, overlap inboard of back-floor reinforcement beam 1 front end and floor front cross rail 2 position of weld, back and with front door sill inner panel 4 between welding lead power reinforcement 3 (combining Fig. 2), lead power reinforcement 3 like this back floor front cross rails 1 and front door sill inner panel 4 are communicated with, make preceding floor front cross rail 1, back-floor reinforcement beam 2, lead power reinforcement 3 and front door sill inner panel 4 forms a cavity 5 in welding region.Simultaneously on front door sill inner panel 4 with welding lead the relative opposite side of power reinforcement 3 weld again one with the auxiliary reinforcement 5 (combining Fig. 3) of leading power reinforcement 3 direction unanimities.Can conduct the power of gusset threshold to the floor effectively like this in side Touch, increase the intensity on floor, arrow is the conduction orientation of side impact force among Fig. 1.
