Description
Technical field
The utility model belongs to vehicular field, relates to a kind of upper supporting traverse of automobile.
Background technology
Become focus and the emphasis of automotive development in modern automobile safety Design, the safety performance of automobile is developed the also continuous protection category from passenger and is extended to the protection category to goers outside vehicle.SUV vehicle requires good in performance, and therefore general comparatively general car is high on chassis, often to pedestrian particularly pedestrian lower leg produce great damage, more can cause leg amputation time serious.Usually on increasing above SUV vehicle front cross rail, supporting traverse protects pedestrian lower leg safety, but due to upper supporting traverse span comparatively large, substantially cover front cross rail length range, upper supporting traverse rigidity exists certain not enough.
Such as a kind of pedestrian protecting crossbeam [application number: CN201220037898.6 for SUV vehicle disclosed in Chinese patent literature; Publication number: CN202463754U], comprise the shank crossbeam be arranged on water tank cross sill, also comprise another and be located at thigh crossbeam on water tank upper beam.This patent have employed structural weakening means, and thigh transverse beam rigidity is a greater impact, if collision impact is comparatively large, thigh crossbeam can bend very soon, and energy-absorbing effect can be had a greatly reduced quality, and causes the thigh of meeting pedestrian to cause serious injury.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of upper supporting traverse of automobile, and the technical matters that the utility model solves is the intensity increasing upper supporting traverse.
The purpose of this utility model realizes by following technical proposal:
A kind of upper supporting traverse of automobile, automobile comprises the front cross rail be fixed on vehicle body, it is characterized in that, described upper supporting traverse comprises supporting traverse body and brace panel, described upper supporting traverse body is fixed on front cross rail by some mounting brackets, and brace panel laminating is fixed on the back side of supporting traverse body.
Upper supporting traverse body adds bend resistance intensity by brace panel; when vehicle and pedestrian collision, in basis, supporting traverse can bear larger impact and not occur situation about fractureing, and can absorb most of impact by actv.; reduce and the thigh of pedestrian is injured, reach the object of protection pedestrian.
In the upper supporting traverse of above-mentioned automobile, described upper supporting traverse body comprises the cross-beam body of cross section in " U " type and the butting section being positioned at cross-beam body two ends, and described mounting bracket and butting section are fixed.This structure increases the resistance to bending of supporting traverse body, increase local stiffness, i.e. resistance capacity to deformation.
In the upper supporting traverse of above-mentioned automobile, described brace panel comprises the support portion of cross section in " U " type and the fixed part being positioned at two ends, support portion, described support zone in the groove of cross-beam body and two lateral surfaces of support portion fit with two medial surfaces of cross-beam body respectively against, have gap between the inner end surface of circular arc that to be the outer face of circular arc and cross-beam body be in described support portion, described fixed part and above-mentioned butting section one_to_one corresponding fit is fixed.It is good that the structure of brace panel has resistance to bending, has stronger resistance capacity to deformation; When occurring to clash into, the thigh of pedestrian at first with the end face of cross-beam body against and make the end face of cross-beam body produce deformation to absorb impact, when the end face of cross-beam body and the end face of support portion against time cross-beam body end-face deformation required for application force larger, also the further deformation of the end face of cross-beam body is just prevented, prevent the bending of supporting traverse body, this structure makes supporting traverse have double-layer structure, add the resistance to bending of supporting traverse, make this physical efficiency of supporting traverse fast speed absorb impact simultaneously, reduce the injury to pedestrian.
In the upper supporting traverse of above-mentioned automobile, described fixed part is equidistantly provided with lug boss, the cross section of described lug boss is semi-circular shape.Lug boss can increase the intensity of fixed part.
In the upper supporting traverse of above-mentioned automobile, described mounting bracket has three, the mounting bracket being positioned at two ends is fixed with the two ends of upper supporting traverse body respectively, the middle part being positioned at Intermediate bracket and upper supporting traverse body is fixed, described brace panel has two pieces, and two pieces of described brace panels are fixed on the position on supporting traverse body between mounting bracket.This structure makes this physical efficiency of supporting traverse firmly be fixed on front cross rail when there is shock, the position intensity of fixing due to upper supporting traverse body and mounting bracket is larger, therefore the fixed position of brace panel can meet the requirement improving upper supporting traverse bulk strength, also can meet the requirement of vehicle weight-saving.
In the upper supporting traverse of above-mentioned automobile, by being welded and fixed between described fixed part and butting section.Do not affect the attractive in appearance of upper supporting traverse body by the mode of welding, can ensure constant intensity yet.
Compared with prior art, the upper supporting traverse of this automobile has resistance to bending and resistance capacity to deformation is strong, has the advantage reduced the injury of pedestrian.
