The utility model aims at providing the front floor structure with the advantages that good support and energy transmission effects can be realized during the lateral collision generation, the transverse deformation of the floor is inhibited, and the injury on passengers is reduced.
Description
Technical field
The utility model relates to a kind of body structure, and in particular, it relates to a kind of preceding floor panel structure.
Background technology
Bump against in type traffic accident at the vehicle that takes place, the probability of occurrence of side collision occupies second.When side collision took place, energy mainly was to transmit and absorb through threshold, B post, side bar etc., and the floor is crew module's a part, and its distortion situation follows the extent of injury to the occupant that direct relation is arranged in collision process.Mostly the floor panel structure that has vehicle now is to adopt single beam structure of installing, and this structure does not have the effect of well support and transfer of energy for side collision.If can adopt two crossbeams of installing; Can play bigger supporting role at the collision center member to threshold so; Simultaneously can carry out transmission of energy again; Can reduce the intrusion amount of threshold like this, occupant's shank is played the certain protection effect, therefore two floor panel structures that crossbeams are installed are necessary conscientiously to prove and suitably adopt.Notification number is the invention of CN100352718C discloses a kind of automobile on December 5th, 2007 a floor bearer structure; Comprise a preceding floor crossmember; Should captive joint transverse to the longitudinal vehicle axis between the threshold that is arranged at two auto body sides and with said threshold by preceding floor crossmember; Also comprise two longerons between threshold; This longeron extends below at the base plate of a downward enclosed cabin from front compartment backward, and the longeron with big cross-sectional plane withstands on the cross-sectional plane with relatively little that also vertically staggers backward on the end plate of preceding floor crossmember and extends below at base plate, and wherein preceding floor crossmember is fixed on the threshold that cuts out by web.This floor bearer structure is under the situation of high self-stiffness; Guarantee that automobile is when collision accident; The freedom of the legroom of particularly optimizing during head-on crash; Power bear that with power transmission is substantially limited under the operator's compartment and after the zone, can solve through special mutual arrangement structure and annexation thereof through longeron, floor crossmember and threshold.But the structure that this invention provides have only single before floor crossmember, anti-side impact limited in one's ability.
The utility model content
In order to overcome the existing single anti-side collision of vehicle deficiency limited in one's ability that crossbeam is installed that adopts; The utility model provides a kind of employing sectional type two beam structures of installing; Reinforcement is to the support on threshold and floor, the preceding floor panel structure of crew module's deformation extent when reducing side impact.
The technical scheme of the utility model is: floor panel structure before a kind of; It is anterior to be located at the vehicle body crew module; Comprise preceding floor; Comprise that also four are installed crossbeam, four the both sides that crossbeam is located at centre gangway symmetrically are installed, four crossbeam is installed and is comprised the left front beam in preceding floor, the left back beam in preceding floor, the right back beam of right front beam in preceding floor and preceding floor; The left front beam in preceding floor, left back beam two ends, preceding floor are fixed on respectively on vehicle body left side threshold and the centre gangway, and the two ends of the right front beam in preceding floor, the right back beam in preceding floor are fixed on respectively on vehicle body right side threshold and the centre gangway.Adopt two crossbeams of installing; Can obtain the side direction holding capacity stronger than common single-beam structure; Crossbeam can play bigger supporting role to threshold and floor when side collision takes place, and can carry out transmission of energy better again simultaneously, can when side collision takes place, resist excessive distortion like this; Reduce the intrusion amount of threshold, the occupant is played the better protect effect.
As preferably, the said crossbeam of respectively installing comprises adapter plate, and said adapter plate comprises sill end adapter plate and centre gangway end adapter plate, and sill end adapter plate and centre gangway end adapter plate are divided into the two ends of said installation crossbeam.Crossbeam is installed is had the comparatively shape of rule usually; Inconvenience and threshold and centre gangway direct connection with relative complex curved-surface structure; Said adapter plate has the curved surface junction surface that coincide and mate with threshold and centre gangway, therefore can be connected for the installation crossbeam provides with the transition of threshold and centre gangway.
As preferably, sill end adapter plate and centre gangway end adapter plate are welded on respectively on threshold and the centre gangway.Welding process is ripe relatively simple, and higher Joint strenght can be provided.
As preferably, the cross-sectional plane of described installation crossbeam, adapter plate all is " several " font, installs on crossbeam, the adapter plate and is equipped with turnup structure.This hollow structure that crossbeam, adapter plate are installed makes it the lightweight as much as possible again of existing intensity preferably, and turnup structure also can increase the intensity that crossbeam and adapter plate are installed.
As preferably, be that said installation crossbeam inside is provided with the crossbeam brace panel, the welded top of crossbeam brace panel is on said installation crossbeam.The crossbeam brace panel is lining in installs crossbeam inside, forms double-decker with crossbeam is installed, thereby the installation crossbeam is played the effect of reinforcement.
As preferably, the crossbeam brace panel is provided with convex tendon.Suppress convex tendon on the crossbeam brace panel, can appropriateness reduce the elasticity of crossbeam brace panel, increase the rigidity of crossbeam brace panel, play the effect of reinforcement.
As preferably, described installation crossbeam is provided with welding knock hole, wire harness hole and mounting hole.The welding knock hole is convenient to install crossbeam and when welded and installed, is accurately located.Because the hollow structure of crossbeam is installed, its inner space can fully utilize the cable tray as electric wiring, and the wire harness hole promptly is the import and export that crossbeam is installed in these circuit turnover.Crossbeam brace panel top with the welding of crossbeam top inner surface is installed, the side of crossbeam brace panel then with crossbeam side bolted connection is installed, it is easier to implement like this, mounting hole supplies to install the usefulness of crossbeam and crossbeam brace panel bolted connection exactly.
As preferably, described adapter plate is provided with chair mounted hole and auxiliary hole.Because adapter plate is positioned at the two ends that crossbeam is installed, be the attachment point that crossbeam is installed, so the chair mounted hole is located at and can guarantee the firm of seat on the adapter plate.Auxiliary hole is located on the side of adapter plate, and shape is rule, and size is bigger, is mainly used in the loss of weight of material.
The beneficial effect of the utility model is:
Can when side collision takes place, play good support and the effect of transmitting energy, suppress the lateral deformation on floor, reduce injury the occupant.
