Description
Technical field
The utility model is related to a kind of auto parts and components, is particularly suitable for the front anti-collision beam of various kart, belongs to
Automobile technical field.
Background technology
Automobile is used and increasingly popularized as one kind transport and walking-replacing tool, but traffic accident also increasing year by year how
In collision scenario accident, the safety of occupant, the damage of reduction automobile important component is protected to turn into each vapour to greatest extent
The direction that man of depot makes great efforts.Collision prevention girders as automobile passive safety system important component, its performance is directly connected to driver
Safety.Low speed collision regulation is even more and strict requirements proposed to auto-safety mechanism, and especially front anticollision beam of automobile is touched
Hit performance.There is phenomenon of rupture in the discovery when frontal collision test is carried out to collision prevention girders, its crossbeam centre position, and this not only breaks up
Collision prevention girders self structures, and impact force can not be delivered on energy-absorption box by crossbeam, and energy-absorption box does not play energy-absorbing work yet
With.This needs designer constantly to change the structure of collision prevention girders, if can't resolve, usual kart manufacturer has to
Receive security performance reality not high.
Preceding anti-collision beam in the market is generally complete uiform section structure, and energy-absorption box is generally uiform section or even variation
Cross section structure.For some pony cars, due to body forward structure narrow space, front anti-collision beam structure is caused to be made with automotive front
Type is easily interfered, and such as collision prevention girders are interfered with fog lamp, and two kinds of settling modes would generally be used in this case：One is to change automobile
Anterior moulding, that is, reduce the installation site of fog lamp, and slot milling is installed to front anti-collision beam, but if early stage moulding has been determined, change
Moulding can bring very big inconvenience；Another way is to reduce the length of energy-absorption box, anti-collision beam installation site is accordingly moved afterwards, is given
Fog lamp reserves installing space, and this method can directly reduce the crash protection performance of collision prevention girders, in collision scenario due to
Energy-absorption box does not have enough energy-absorbing spaces, causes that energy can not be effectively absorbed, it is difficult to meet every safe performance indexes, this is
Auto vendor and consumer are unacceptable.
Utility model content

Using the shaping of the arc of radius such as roll-in uiform section, its cross sectional shape is B fonts to crossbeam,
Further, the crossbeam antetheca is waveform wallboard, and the crest on the waveform wallboard is along crossbeam length side
To extending to crossbeam or so two ends.
Further, it is 2-6 that the crossbeam antetheca sets crest number.
Further, the crest and the difference in height of crossbeam antetheca plane are 3-13mm.
Further, the length dimension D of the crossbeam intermediate cross-section is 90-160mm, and width dimensions L is 35-46mm.
Further, a preceding lower end unfilled corner for rectangle, the energy-absorption box are respectively cut in the lower section at the left and right two ends of the crossbeam
Preceding lower end is provided with energy-absorption box unfilled corner.
Further, be provided with crossbeam side base plate at described preceding lower end unfilled corner, crossbeam side base plate perpendicular to
Crossbeam cross section.
Further, the energy-absorption box includes energy-absorbing box plate, before the energy-absorption box unfilled corner is by being arranged on energy-absorbing box plate
The knuckle of lower end is constituted, and knuckle is 130-160 ° with the angle β of energy-absorbing box plate, the knuckle front portion to crossbeam side base plate at
Extend, and welded by connecting plate and crossbeam side base plate.
Further, the relation of the height dimension D in the middle of the height dimension d and crossbeam at the crossbeam two ends is d=0.7 D
-0.8D。
Further, the energy-absorption box length dimension H is 120mm.
Compared to existing technology, the utility model is used by changing crossbeam and energy-absorption box structure design by crossbeam antetheca
Waveform wallboard, improves the intensity of crossbeam, more efficiently transmits impact force to energy-absorption box, improves the safety of automobile
Property, while a rectangle unfilled corner being made up of the preceding lower end unfilled corner of crossbeam and the preceding lower end unfilled corner of energy-absorption box is respectively cut in the both sides of crossbeam,
Space is stopped to automotive front end moulding, and has fully ensured that collision prevention girders security performance, before energy-absorption box effective length is ensured
Put, fog lamp setting height(from bottom) can not be reduced, solve some vehicle front anti-collision beam structures conflicting with front part of vehicle moulding
Contradiction, with simple and practical, is easy to dismounting to repair, the advantages of mitigating collision prevention girders and conduct oneself with dignity.
