Existing automobile front floor centre gangway constructional depth is darker, only depends on two girder works of bottom to support during automobile generation head-on crash, and intensity is relatively poor, causes the extruding to member in the compartment during collision easily, and safety performance is relatively poor.One Chinese patent application (publication number: CN 201484507U) disclose a kind of middle channel architecture of auto body base plate; This structure comprise in channel body and with this in integrated two side flangings of channel body; Should be axially arranged with first cavity in the middle of the middle channel body; This two side flanging axially is provided with reinforced rib respectively, and formation cross section in rear portion of channel body is trapezoidal level and smooth transition face in this; This passage has increased the faying surface with preceding floor, and the structure of enclosed beam is made in the place that will overlap; In addition, the middle brace panel of this passage also constitutes two beams with forward and backward seat crossbeam and is supporting threshold with the back brace panel.Though should in channel architecture have side impact performance preferably, the pipeline of power when simultaneously also having increased central collision, should in the axial intensity of channel architecture still relatively poor, the central collision performance a little less than, safety factor is lower.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind ofly can strengthen automobile front floor centre gangway axial strength, increases its central collision performance, improves the additional strengthening of the automobile front floor centre gangway of automotive safety coefficient.
The purpose of the utility model can realize through following technical proposal: a kind of additional strengthening of automobile front floor centre gangway; This automobile front floor centre gangway comprises that the cross section is the centre gangway body that echelon form and both sides have flange; This additional strengthening comprises having the following preceding brace panel and down middle brace panel that arches upward; The two ends of described down preceding brace panel and down middle brace panel are connected with the flange of centre gangway body both sides respectively mutually; It is characterized in that; This additional strengthening also comprises the reinforcement that is strip, and described reinforcement is axially disposed within the centre gangway body and is connected with the centre gangway body, the two ends of described reinforcement respectively with down before brace panel be connected with down middle brace panel.
The additional strengthening of this automobile front floor centre gangway is provided with reinforcement through brace panel before plate centre gangway previously following with down between the brace panel, has strengthened the axial intensity of preceding floor centre gangway, has increased the performance of central collision, has improved the safety factor of automobile.
In the additional strengthening of above-mentioned automobile front floor centre gangway, described reinforcement is one and strengthens plate that described reinforcement plate is positioned at the middle part of centre gangway body.
In the additional strengthening of above-mentioned automobile front floor centre gangway, the width of described reinforcement plate is 80～140mm.The width of strengthening plate can actv. improves the intensity of preceding floor centre gangway in the application's scope, increase its central collision performance, can not influence the weight of vehicle body simultaneously again, has guaranteed the light-weight design of vehicle body.
In the additional strengthening of above-mentioned automobile front floor centre gangway, described reinforcement comprises two reinforcement plates, and described two reinforcement plates laterally arrange and two ends are connected with down middle brace panel with down preceding brace panel respectively.Two reinforcement plates laterally arrange, and brace panel constitutes a support frame with down middle brace panel before down, and intensity is higher.
In the additional strengthening of above-mentioned automobile front floor centre gangway, the width of described reinforcement plate is 60～80mm.The width of strengthening plate can actv. improves the intensity of preceding floor centre gangway in the application's scope, increase its central collision performance, can not influence the weight of vehicle body simultaneously again, has guaranteed the light-weight design of vehicle body.
In the additional strengthening of above-mentioned automobile front floor centre gangway, described reinforcement plate and centre gangway body, down before brace panel and down between the brace panel all through being welded to connect.Strengthening plate is connected through spot welded mode between brace panel and the down middle brace panel with the centre gangway body, before down; Reach the effect that makes down a preceding brace panel and a part of down middle brace panel merging becoming, also reached the purpose of body lightening when strengthening preceding floor centre gangway intensity.
In the additional strengthening of above-mentioned automobile front floor centre gangway, described reinforcement plate adopts HSLA to process.Reinforcement plate employing HSLA is processed has higher intensity, good combination property, and service life is longer, and simultaneously required cost is also lower.
Compared with prior art, the additional strengthening of this automobile front floor centre gangway cross before plate centre gangway previously following brace panel and down in the reinforcement plate is set between the brace panel, strengthened the axial intensity of preceding floor centre gangway; Increase the performance of central collision, improved the safety factor of automobile, guaranteed the light-weight design of vehicle body simultaneously again; Simple in structure; Easy to make, required cost is lower, has better economic and is worth and market outlook.
