Abstract
The invention discloses an automobile front anti-collision beam. The automobile front anti-collision beam comprises an arc beam, connecting plates, energy absorbing boxes and installing plates, wherein the two ends of the beam are connected with the energy absorbing boxes through the connecting plates, and the energy absorbing boxes are fastened into a bodywork longeron assembly through the installing plates and bolts; on one hand, the beam is formed in a uniform section and equivalent radius arc mode through rolling, and the cross section is of the B type. Compared with previous planar wall board, the structure improves strength of the beam, impact force is more effectively transmitted to the energy absorbing boxes, and safety performance of an automobile is improved; on the other hand, two rectangular notches are cut in the two sides of the beam respectively, each notch is composed of a notch in the front and lower end of the beam and a notch in the front and lower end of the corresponding energy absorbing box, and the contradiction of part conflicting is solved. The automobile front anti-collision beam has the advantages of being safe and reliable in performance, simple, practical and convenient to assemble, disassemble and maintain, dead weight of the anti-collision beam is reduced.
Description
Technical field
The present invention relates to a kind of auto parts and components, are particularly suitable for the front anti-collision beam of various kart, belong to automobile
Technical field.
Background technology
Automobile is used and increasingly popularizes as a kind of transport and walking-replacing tool, but vehicle accident is also increasing year by year how
In collision scenario accident, the damage that is safe, reducing automobile vitals of protection occupant to greatest extent becomes each vapour
The direction that man of depot makes great efforts.Collision prevention girders are used as the vitals of automobile passive safety system, and its performance is directly connected to driver
Safety.Low speed collision regulation is even more and proposes strict requirements to auto-safety mechanism, especially the touching of front anticollision beam of automobile
Hit performance.The discovery when frontal collision test is carried out to collision prevention girders, there is phenomenon of rupture in its crossbeam centre position, and this not only breaks up
Collision prevention girders self structure, 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 the not high reality of security performance.
Front anti-collision beam in the market mostly is complete uiform section structure, and energy-absorption box mostly is 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, would generally adopt two kinds of settling modes in this case：One is to change automobile
Anterior moulding, that is, reduce the installation site of fog lamp, installs slot milling to front anti-collision beam, but if early stage moulding is fixed, change
Moulding can bring very big inconvenience；Another way is to reduce the length of energy-absorption box, so that anti-collision beam installation site is accordingly moved afterwards, gives
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 to effectively absorb energy, it is difficult to meet every safe performance indexes, this is
Auto vendor and consumer are unacceptable.
Content of the invention
The present invention is used for solving the defect of above-mentioned prior art and providing a kind of improvement beam structure that passes through and design, on the one hand
The intensity of crossbeam is effectively lifted, on the other hand can not only have been reserved fog lamp installation site but also energy-absorption box can be kept there is provided a kind of
The front anticollision beam of automobile of length.
For realizing the purpose of the present invention, the technical scheme for being adopted is：
A kind of front anticollision beam of automobile, it includes curved cross member, connecting plate, energy-absorption box and installing plate, and the crossbeam two ends lead to respectively
Connecting plate connection energy-absorption box is crossed, is fastened on chassis runner assembly by installing plate and bolt on the energy-absorption box；The crossbeam
Using the arc of radius molding such as roll-in uiform section, its cross sectional shape is B font,
Further, the crossbeam antetheca is that waveform wallboard, the crest on the waveform wallboard prolongs along crossbeam length direction
Extend crossbeam or so two ends.
Further, it is 2-6 that the crossbeam antetheca arranges crest number.
Further, the crest is 3-13mm with the difference in height of crossbeam antetheca plane.
Further, the length dimension D of the crossbeam intermediate cross-section is 35-46mm for 90-160mm, width dimensions L.
Further, the front lower end unfilled corner of a rectangle, the energy-absorption box are respectively cut in the lower section at the left and right two ends of the crossbeam
Front lower end is provided with energy-absorption box unfilled corner.
Further, be provided with crossbeam side base plate at described front lower end unfilled corner, crossbeam side base plate perpendicular to
Crossbeam cross section.
Further, the energy-absorption box includes energy-absorbing box plate, and the energy-absorption box unfilled corner is by being arranged on before 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, and the knuckle front portion is at the base plate of crossbeam side
Extend, and welded with crossbeam side base plate by connecting plate.
Further, the relation of the middle height dimension D of the height dimension d at the crossbeam two ends and crossbeam is d=0.7 D
-0.8D.
Further, the energy-absorption box length dimension H is 120mm.
Compared to existing technology, the present invention adopts wave by changing crossbeam and energy-absorption box structure design by crossbeam antetheca
Shape wallboard, improves the intensity of crossbeam, and more efficiently transmission impact force improves the safety of automobile on energy-absorption box, with
When respectively cut a rectangle unfilled corner being made up of the front lower end unfilled corner of crossbeam and the front lower end unfilled corner of energy-absorption box in the both sides of crossbeam, to automobile
Space has been stopped in front end moulding, and has fully ensured that collision prevention girders security performance, on the premise of energy-absorption box effective length is ensured, can
Do not reduce fog lamp setting height(from bottom), some vehicle front anti-collision beam structures and the conflicting contradiction of front part of vehicle moulding is solved, tool
Have simple and practical, be easy to dismounting maintenance, mitigate collision prevention girders the advantages of conduct oneself with dignity.
