A kind of bump-proof rod for automobile door
The present invention relates to technical field of automobile parts, more particularly, to a kind of bump-proof rod for automobile door.
In traffic accident, side collision is that occur frequency highest Crash characteristics, accident and dead caused by side collision
The number of dying is only second to head-on crash row second.Touched due to there is no enough spaces to produce big deformation between occupant and car door to absorb
Energy is hit, so side collision seems especially dangerous in traffic accident.In recent years, the safe design of side collision is used as vapour
Car one of most important factor safely.In order to reduce injury of the occupant in side collision, it is necessary to which one safely and effectively passive
Safety device.The side crashworthiness of vehicle is improved, in addition to improving the intensity of body side wall, preventing car door intrusion and various preventing car doors
The research for hitting beam is also carried out extensively in each automobile power of the world.Door anti-collision joist is resisted side as the reinforcer of car door and touched
Hit, early stage side collision occurs, door anti-collision joist is deformed and absorbs the energy of collision generation and play reduction occupant
The purpose of injury.
The content of the invention
It is an object of the invention to provide a kind of cheap and safe and reliable bump-proof rod for automobile door of manufacturing cost.
In order to solve the above technical problems, the present invention is adopted the following technical scheme that：
A kind of bump-proof rod for automobile door, including crash bar and the connecting plate installed in the crash bar two ends, the crash bar
Material is aluminium alloy or super-high strength steel, and its cross section is circular or square；The connecting plate is Z-shaped configuration, and its material is
Ultra-high strength steel plate simultaneously passes through cold stamping monolithic molding；Mounting hole and multiple tracks reinforcement are provided with the connecting plate.
Compared with prior art, beneficial effects of the present invention are：
A kind of bump-proof rod for automobile door of the present invention, using aluminium alloy or the crash bar of super-high strength steel material, is highly resistant to external force
Side collision is resisted, connection plate device is designed at crash bar two ends, the versatility of product and the convenience of installation can be effectively improved.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present invention；
Fig. 2 is partial enlargement structural representation at A of the present invention.
Referring to shown in accompanying drawing 1-2, a kind of bump-proof rod for automobile door, including crash bar 1 and installed in the crash bar two ends
Connecting plate 2, the material of the crash bar 1 is aluminium alloy or super-high strength steel, and its cross section is circular or square；The connecting plate
2 be Z-shaped configuration, and its material is ultra-high strength steel plate and passes through cold stamping monolithic molding；Provided with installation on the connecting plate 2
Hole 3 and multiple tracks reinforcement 4.
A kind of bump-proof rod for automobile door of the present invention, using aluminium alloy or the crash bar of super-high strength steel material, is highly resistant to
External force resists side collision, crash bar two ends design connection plate device, can effectively improve product versatility and installation just
It is described above, it is only the preferred embodiments of the present invention, is not the limitation that other forms are done to the present invention,
Any those skilled in the art are changed or are modified as equivalent variations possibly also with the technology contents of the disclosure above
Equivalent embodiment.But, every without departing from the present invention program content, the technical spirit according to the present invention is done to above example
Any simple modification, equivalent variations and remodeling, still fall within protection scope of the present invention.
