Abstract
The invention discloses a high-strength anti-collision steel beam and relates to the technical field of automobiles, in particular to an automobile front and back bumper anti-collision steel beam. The high-strength anti-collision steel beam is invented for improving the automobile body strength and traffic safety of an automobile. A main body of the high-strength anti-collision steel beam is an airtight container, namely a pressure container with an outer geometrical shape similar to the anti-collision steel beam, and is filled with a high-pressure gas medium so as to improve the mechanical strength. The high-strength anti-collision steel beam is simple in structure and high in practicality, can be applied to various kinds of automobiles for improving the safety of the automobiles during collision and guaranteeing the safety of the automobiles and safety of passengers in the automobiles. The geometrical shape of the anti-collision steel beam is changed to be perfectly combined with the automobile, the aesthetic performance of the automobile is not affected, the performance is reliable and stable, and the service life is long.
Description
Technical field
The present invention relates to technical field of vehicle safety, be specifically related to crashproof girder steel before and after a kind of automobile.
Background technology
Automobile collision preventing girder steel is the important ingredient of Hyundai Motor structure as safety device, and it is colliding
Time absorb and slow down foreign impacts power, effectively alleviate casualties degree and amount of vehicle damage.Automobile collision preventing girder steel at present
Material and structure are varied, frothy, and aluminium alloy extrusions also has steel plate punched molding, protect at present before and after major part automobile
The crashproof fine strain of millet of main body of danger thick stick becomes channel-section steel with steel plate punched, and this bumper head or afterbody when there is severe crash are crushed
Deformation is serious and is difficult to restore simultaneously, needs to change, it is impossible to well protect car body component, electromotor and passenger inside the vehicle's safety,
Reason is insufficient strength.The materials thickness of crashproof girder steel substantially determines intensity and the safety of crashproof girder steel, and materials are sturdy
Crashproof girder steel this design original intention with lightweight vehicle body energy-saving, emission-reducing, environment friendly more thick and heavy mutually run counter to, and the most unrestrained
Take resource.Therefore people are laying siege to a kind of beneficially safety, and simply, environmental protection, light weight can have again sufficient intensity
Crashproof girder steel.
Summary of the invention
Bicycle tyre it is equally known that it is made up of soft and whippy rubber and nylon wire, but he
A people two people even weight of three people can be born after full gas.Easy open can beverage believes that everybody drank, he
Before opening, appearance is the most solid, and even tramping with one's feet, it is not bad also to step on, after opening, easy to do can pinch with hands flat.Same
One thing is before release, and after inside is full of pressure, the external force load born significantly increases.Such example is very
Many, why this is！Reason is very simple, and first their own is an airtight container, and the pressure of their interior media
Superatmospheric, the pressure of internal high pressure medium is uniformly flooded with the internal every nook and cranny, each direction of container, limited airtight
The existence having pressure in space which forms pressure vessel.
The present invention is combined with each other automobile collision preventing girder steel and pressure vessel, purpose in order to overcome above-mentioned crashproof girder steel
Intensity is not enough, utilizes pressure vessel high-pressure medium to the outside pressure of inner surface of container, in the case of not increasing quality, increases
The intensity of crashproof girder steel.
High strength anti-collision girder steel includes the main body cover 2 of crashproof girder steel, high-pressure gas medium 1, the installation on collision prevention girders both sides
Bearing 6 and fixing bolt 7 impact energy absorption box 8 and vehicle body side member are fixed into entirety, and vehicle body and occupant are protected in common effect
Safety.
High strength anti-collision girder steel and conventional crash girder steel compare and it is characterized in that, the main body cover 2 of collision prevention girders itself is close
Close container, and be that inside is filled with high-pressure gas medium 1, be used for improving collision prevention girders main part mechanical strength.Collision prevention girders
Main body is the airtight entirety constituted that is connected by a confined space or multiple space, such as Figure of description Fig. 4 and explanation
Shown in book accompanying drawing Fig. 5.Separated by gusset between each space and be interconnected.The main body of crashproof girder steel is provided with pressure
Sensor 3 charging connector 4 and relief valve 5 valve 4 are for make-up gas so that it is collision prevention girders body interior can reach and keep certain
Pressure.Pressure transducer 3 is for monitoring the pressure of crashproof girder steel main internal gas medium.Relief valve 5 is to prevent by temperature etc.
Other influences factor, when causing high-pressure gas medium 1 hypertonia to exceed safety value, release portion gas reduces collision prevention girders main body
In the range of shell 2 internal pressure drops to safety value.
Accompanying drawing explanation
Figure of abstract:
Figure of description Fig. 1: automobile collision preventing girder steel schematic diagram
Figure of description Fig. 2: automobile collision preventing girder steel schematic diagram partial enlargement
Figure of description Fig. 3: automobile collision preventing girder steel cross-section structure 1
Figure of description Fig. 4: automobile collision preventing girder steel cross-section structure 2
Figure of description Fig. 5: automobile collision preventing girder steel cross-section structure 3
Accompanying drawing part symbol annotates: 1. high-pressure gas medium 2. crashproof girder steel main body cover 3. pressure transducer 4. gas
Bolt 8. collision energy absorbing box fixed by mouth 5. pressure relief safety valve 6. hold-down support 7.
Merits and demerits compared with girder steel crashproof with routine:
First 3 kinds of the crashproof girder steel of upper table, are some automobiles sold, the most frequently used crashproof girder steel, merits and demerits aobvious and
It is clear to.4th kind is the crashproof girder steel of rubber pneumatic bag formula, owing to placing rubber pneumatic bag inside bumper, and complicated structure, and
And the non-oxidizability of rubber, compare with metal poor, cause the life-span shorter, the most also with regard to about 5 years, rubber pneumatic bag is oxidized
Air-tightness and reliability are substantially reduced, because the limited pressure that rubber bears is so intensity is not the highest later.
It can be seen that high strength anti-collision girder steel, cost than irony punching structure crashproof girder steel cost is slightly higher, but therefore
And bring, high security, it is highly that this point on cost puts into.
