Lotus, to reduce or eliminate the deformation of the framing component of vehicle body.
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 side wall of vehicle body or so, it, can by deforming side wall
Energy when colliding to be absorbed by side wall.That is, center beam of bumper is designed to by making side wall absorb impact energy, to inhibit
The deformation of the driver's cabin of automobile.
Domestic patent database disclosed some similar center beam of bumper technical reports in recent years:
[application number] ZL2016800424044, [title] center beam of bumper, [publication number] CN107848477A, a kind of insurance
Thick stick beam, which includes interior section and exterior section, between interior section and each comfortable top of exterior section and bottom end
Extend.At least one of exterior section or interior section include a pair of of geometrical characteristic portion, this is to each in geometrical characteristic portion
Person is arranged and is arranged to one of corresponding to top or bottom end adjacent with the relationship being separated from each other.Roof and bottom wall are respectively
The another one that exterior section or interior section are extended to from a geometrical characteristic portion in geometrical characteristic portion, by center beam of bumper
Exterior section and interior section interconnect, but since the device does not have the structure that classification absorbs, there are processing shock loadings
It is not flexible, the problem of assimilation effect difference.
Summary of the invention
The center beam of bumper with polymeric filler that the utility model provides a kind of flexible grading, rupture absorbs, solution
Existing structure impact loading handles not flexible, the problem of assimilation effect difference.
The utility model provides a kind of center beam of bumper with polymeric filler, including protects vehicle for collision process
With the center beam of bumper of passenger, crumple support column for being mounted on center beam of bumper on vehicle frame has on crumple support column
Mounting flange, has bolt mounting holes on mounting flange, and bolt passes through bolt mounting holes and mounting flange is fixed on vehicle frame
On, three crumple support columns are fixedly connected with mounting flange and center beam of bumper, and center beam of bumper is made up of metal material frame
First chamber 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,
Second chamber is filled with polymeric filler, has in first chamber and uses the molding open support core of aluminium alloy one tension and compression,
First chamber inner wall is 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 molding.
The polymeric filler limiting force born when until broken that experiences a shock is less than open support core and is subjected to
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 utility model absorbs the structure design of shock loading using multi-chamber classification, and the cavity structure of open support core is opened up
The wide absorption region of impact loading, front of the car is absorbed by the material breaks of classification, foreign object pair when safety accident occurs
The shock loading limiting figure of the shock loading of vehicle, absorption is larger, and effectively flexibility shares absorption impact force, avoids biggish
Rigid shock generates compared with major injury the passenger in carriage, solves existing structure impact loading and handles not flexible, absorption
The problem of effect difference has reduction impact effect significant, and passive security protects, advantage applied widely.

Specific embodiment
Below with reference to specific drawings and examples, the utility model is described in further detail.
As shown in Figs. 1-2, the utility model mainly includes the center beam of bumper 4 for collision process protection vehicle and passenger,
Crumple support column 3 for being mounted on center beam of bumper 4 on vehicle frame has mounting flange 1, installation on crumple support column 3
There are bolt mounting holes 2, bolt passes through bolt mounting holes 2 and mounting flange 1 is fixed on vehicle frame, and three are burst on flange 1
Contracting support column 3 is fixedly connected with mounting flange 1 and center beam of bumper 4, and center beam of bumper 4 constitutes first by metal material frame 41
Chamber 5 and second chamber 6, first chamber 5 are located at close to 3 side of crumple support column, and second chamber 6 is located remotely from crumple support column 3
Side, second chamber 6 are filled with polymeric filler 42, have in first chamber 5 molding porous using the tension and compression of aluminium alloy one
Supporting-core 43,5 inner wall of first chamber are 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 molding.
The limiting force born when until broken that experiences a shock of polymeric filler 42 is less than open support core 43 and is subjected to rushing
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 Figure 1-3, when safety accident occurs for front of the car, center beam of bumper 4 is worked as punching by shock loading when work
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 is absorbed front of the car by the material breaks of classification and impact of the foreign object to vehicle when safety accident occurs
Load, effectively flexibility shares absorption impact force, and biggish rigid shock is avoided to generate compared with major injury the passenger in carriage.
