Description
Technical field
The invention belongs to vehicle passive security protective device technical fields.
Background technology
Currently, the automotive bumper beam on body of a motor car mostly uses greatly 980MPa grades of steel plate, and be formed as
The section orthogonal with its length direction is in B fonts, protects an occupant from impact.Known vehicle bumper module is for providing energy
Absorption characteristic.Typical vehicle bumper assembly includes center beam of bumper and a pair of of collapse box for car.Collapse box for car is positioned in body structure
Framing component end on, and be also fixed on center beam of bumper and carried to absorb impact with certain predetermined value
Lotus, to reduce or eliminate vehicle body framing component deformation.
The main function of automotive bumper beam is：When with object collision is collided, self-deformation passes through own absorption
Impact energy when collision, and when collision, shock loading is passed to the gusset of vehicle body or so, it, can by making gusset deform
Energy when colliding to be absorbed by gusset.That is, center beam of bumper is designed to by making gusset absorb impact energy, to inhibit
The deformation of the driver's cabin of automobile.
Domestic patent database disclosed some similar center beam of bumper technology reports in recent years：
【Application number】ZL2016800424044,【Title】Center beam of bumper,【Publication number】CN107848477A, a kind of center beam of bumper,
The center beam of bumper includes interior section and exterior section, is extended between interior section and each comfortable top of exterior section and bottom end.
At least one of exterior section or interior section include a pair of of geometric properties portion, this is to each of geometric properties portion with that
This relationship spaced apart is arranged and is arranged to one of corresponding to top or bottom end adjacent.Roof and bottom wall are respectively since geometry
A geometric properties portion in features extends to the another one of exterior section or interior section, by the external portion of center beam of bumper
Point and interior section interconnect, but due to the device do not have classification absorb structure, exist processing shock loading it is not flexible,
The problem of assimilation effect difference.
Invention content
The center beam of bumper with polymeric filler that the present invention provides a kind of flexible grading, rupture absorbs, solution are existing
Structure impact loading handle not flexible, the problem of assimilation effect difference.
The present invention provides a kind of center beam of bumper with polymeric filler, including is used for collision process protection vehicle and multiplies
The center beam of bumper of visitor has installation for the crumple support column by center beam of bumper on vehicle frame on crumple support column
There are on mounting flange flange bolt mounting holes, bolt mounting flange to be fixed on vehicle frame across bolt mounting holes, and three
A crumple support column is fixedly connected with mounting flange and center beam of bumper, and center beam of bumper constitutes the first chamber by metal material frame
Room and second chamber, first chamber are located at close to crumple support column side, and second chamber is located remotely from crumple support column side, the second chamber
Room is filled with polymeric filler, has in first chamber and uses the molding open support core of aluminium alloy one tension and compression, the first chamber
Chamber interior walls are fixedly connected with open support core.
The mode that the crumple support column is fixedly connected with mounting flange and center beam of bumper has welding, riveting, bolt to connect
It connects.
The polymeric filler is polystyrene foam.
The mode that the first chamber inner wall is fixedly connected with open support core is metal adhesive gluing, molten weldering, one
Body formula tension and compression are molded.
The polymeric filler limiting force born when until broken that experiences a shock is subjected to less than open support core
The limiting force that impact is born when until broken.
The cavity structure of the open support core has honeycomb-shaped structure, corrugation slab structure.
The present invention absorbs the structure design of shock loading using multi-chamber classification, and the cavity structure of open support core is widened
The absorption region of impact loading, by the material breaks of classification come foreign object when absorbing front of the car generation safety accident to vehicle
Shock loading, the shock loading limiting figure of absorption is larger, and effectively flexibility shares absorption impact force, avoids larger rigidity
It impacts and the passenger in car is generated compared with major injury, solve existing structure impact loading and handle not flexible, assimilation effect
The problem of difference has reduction impact effect notable, and passive security protects, advantage applied widely.

Specific implementation mode
With reference to specific drawings and examples, the invention will be further described.
As shown in Figs. 1-2, it the invention mainly comprises the center beam of bumper 4 for protecting vehicle and passenger for collision process, is used for
Center beam of bumper 4 is mounted on the crumple support column 3 on vehicle frame, there is mounting flange 1, mounting flange 1 on crumple support column 3
It is upper that there are bolt mounting holes 2, bolt mounting flange 1 to be fixed on vehicle frame across bolt mounting holes 2, three crumple supports
Column 3 is fixedly connected with mounting flange 1 and center beam of bumper 4, and center beam of bumper 4 constitutes first chamber 5 by metal material frame 41
With second chamber 6, first chamber 5 is located at close to 3 side of crumple support column, and second chamber 6 is located remotely from 3 side of crumple support column, the
Two chambers 6 are filled with polymeric filler 42, have in first chamber 5 and use the molding open support core of aluminium alloy one tension and compression
43,5 inner wall of first chamber is fixedly connected with open support core 43.
The mode that crumple support column 3 is fixedly connected with mounting flange 1 and center beam of bumper 4 has welding, rivets, is bolted.
Polymeric filler 42 is polystyrene foam.
The mode that 5 inner wall of first chamber is fixedly connected with open support core 43 is metal adhesive gluing, molten weldering, integral type
Tension and compression are molded.
The limiting force born when until broken that experiences a shock of polymeric filler 42 is subjected to rushing less than open support core 43
Hit the limiting force born when until broken.
The cavity structure of open support core 43 is honeycomb-shaped structure 44.
As shown in figure 3, the cavity structure of open support core 43 is corrugation slab structure 45.
As shown in Figs. 1-3, when work, when safety accident occurs for front of the car, center beam of bumper 4 is worked as punching by shock loading
Hit load it is smaller when, 41 depressed deformation of metal material frame loss offset impact force, with the increase of shock loading, macromolecule is filled out
It fills object 42 to occur to be crushed, impact force is absorbed by material fragmentation, when the increase of shock loading further increases, second chamber 6 exists
It is further totally disrupted under shock loading, 42 structure of polymeric filler is destroyed completely, the open support in first chamber 5
Core 43 further absorbs impact force, and the cavity structure of open support core 43 has widened the absorption region of impact loading, first
After open support core 43 in chamber 5 is entirely ineffective, crumple support column 3 ruptures compression under impact force action, further absorbs
Remaining shock loading, by the material breaks of classification come impact of the foreign object to vehicle when absorbing front of the car generation safety accident
Load, effectively flexibility share absorption impact force, avoid larger rigid shock in car passenger generate compared with major injury.
