Description
Technical field
The utility model belongs to field of automobile, relates to longeron connection structure in the front floor of a kind of auto body.
Background technology
Critical parts in auto body Path of Force Transfer is vehicle body keystone configuration, carry load and energy-absorbing in vehicle collisions, be the main determining factor that can crashing vehicle obtain high star safety evaluation, but on body force transferring path, the reasonableness of structure design, utility, technique are realisation is all the main cause of impact collision result.Structure design in Path of Force Transfer, not accomplishes in one move, and needs trial repeatedly, improvement, optimization, checking could realize optimum design effect.As the novel exploration of automotive field energy-conserving and environment-protective, market there is increasing electronlmobil, electronlmobil increases the power battery module of about 200kg on the basis of former vehicle curb mass, the increase of curb mass is proposed higher challenge to vehicle body load and energy-absorbing obviously, therefore in Path of Force Transfer, the design rationality of framing member and utility must highlight, and most important.
In existing automobile front floor, longeron front end is transverse design, overlaps with front longitudinal floor beam, and outside the bending region of its installation site plate longeron previously, meaningless to front longitudinal floor beam bending resistance distortion, its structure design is also unreasonable; Secondly, after front side member in end floor beam and front floor longeron install misplace excessive, the collision impact that before in collision, longitudinal floor beam bears cannot effectively pass in floor on longeron fast, causes front longitudinal floor beam to be out of shape in an impact excessive, unfavorable to passenger protection; In addition, longeron front end transverse lap in front floor, cannot pass to rear end structure effectively fast by impulsive force in collision collision.
Summary of the invention
The problems referred to above that the utility model exists for existing technology, there is provided longeron connection structure in the front floor of a kind of auto body, technical problem to be solved in the utility model is: how to improve in the front floor of auto body longeron connection structure to improve its collision safety performance.
The purpose of this utility model realizes by following technical proposal:
Longeron connection structure in a kind of front floor of auto body, auto body front wall comprises front panel, right side crossbeam, longeron in front longitudinal floor beam and front floor, described front longitudinal floor beam is by right side crossbeam and front panel, be connected on the right side of cabin longeron and vehicle body, in described front floor, longeron is connected with on the left of vehicle body by centre cross member, it is characterized in that, in centre cross member and described front floor, the front end of longeron is connected, in described front floor, the rear end of longeron is connected with body tail, the connecting panel of arc is provided with between longeron and front longitudinal floor beam in described front floor, in described connecting panel one end and described front floor, the front end of longeron is connected, the front end of the described connecting panel other end and described front longitudinal floor beam is connected.
Its principle is as follows: electronlmobil is after increase power battery module; in collision process, impulsive force and impact energy increase; and in existing body structure in front floor longeron front-end architecture irrationality design; make cannot play maximum effect in collision process and effectively transmit impulsive force; also cause front panel intrusion volume to remain high simultaneously, unfavorable to passenger protection.The technical program promotes from reasonable in design and utility, redesign longeron connection structure in the front floor of auto body, by arranging the connecting panel of arc in plate previously between longeron and front longitudinal floor beam, in connecting panel one end and front floor, the front end of longeron is connected, the other end is connected with the direct front end with front longitudinal floor beam, and right side crossbeam is also connected with the front end of front longitudinal floor beam, in such right side crossbeam and front floor, longeron front-end architecture access path shortens, and the transmission of power is more direct and smooth; Connecting panel can keep out intrusion when front panel is hit, and is gone out by force dispersion.
The technical program is the improvement to body platform place force transferring structure; this structure design is relatively simple; forming process requires lower; obvious to Collision-free deformation effect; effectively raise the performance of vehicle body load, bending resistance distortion aspect, to reducing the intrusion volume of front panel and promoting passenger protection effect clearly.
It is front that orientation all around in technique scheme refers to headstock direction, after tailstock direction is, towards headstock dorsad the tailstock time, left-hand side is left, and right-hand side be the right side,
In the front floor of above-mentioned auto body in longeron connection structure, described connecting panel one end is relative with longeron in front floor and smoothly connect with the front end of longeron in centre cross member, front floor, and the described connecting panel other end is relative with right side crossbeam and smoothly connect with the front end of right side crossbeam, front longitudinal floor beam.Connecting panel one end and front longitudinal floor beam closely overlap, and its structure is smooth to longeron and centre gangway place in front floor, and in front floor, longeron, connecting panel and centre cross member three form one " trident " arrangement overlap joint, and impulsive force is distribution and transmission herein; Make the power transmission between body structure more smooth and rapid, the control of front wall intrusion volume is significantly promoted.Infrastructure cost after simultaneously improving and weight little with difference before, structure is relatively simple, less demanding to forming process, following other change money vehicle is carried out very convenient.
In the front floor of above-mentioned auto body in longeron connection structure, the both sides of described connecting panel all have downward flange, and described flange outer is also provided with the flanging paralleled with described connecting panel.This flanging and flange can provide the support strength of connecting panel, also can be convenient to be welded and fixed.
In the front floor of above-mentioned auto body in longeron connection structure, described connecting panel be quarter circular arc and the outside of described connecting panel towards front panel.By the connecting panel arranging arc, the cavity space of longeron front end in front floor is increased, and installation site is just in time positioned at front longitudinal floor beam easily bends deformed region, the intrusion of front panel can be reduced by the load bearing face of arc.
In the front floor of above-mentioned auto body in longeron connection structure, described connecting panel adopts No. 45 steel to make.No. 45 steel have higher intensity and machinability, can obtain certain toughness, plasticity and resistance to abrasion after suitable heat treatment, and material source is convenient.And can be connected by longeron in hydrogen brazing and argon arc welding and front floor.
Compared with prior art, advantage of the present utility model is as follows:
1, in the front floor of this auto body, the design of longeron connection structure is relatively simple; forming process requires lower; obvious to Collision-free deformation effect, effectively raise the performance of vehicle body load, bending resistance distortion aspect, to reducing the intrusion volume of front panel and promoting passenger protection effect clearly.
2, by the connecting panel arranging arc, the cavity space of longeron front end in front floor is increased in longeron connection structure in the front floor of this auto body, and installation site is just in time positioned at front longitudinal floor beam easily bends deformed region, the intrusion of front panel can be reduced by the load bearing face of arc.
