Description
Technical field
The utility model relates to automobile door structure field more particularly to a kind of arrangements for automotive doors with Crashworthy plate.
Background technique
Since automobile is born, safety problem is always market and consumer's focus of attention and a outstanding vapour
The basic quality of vehicle product indispensability.And currently, whether most of consumer judgement automotive safety on the market, in addition to seeing its safety
Except configuration, also need to examine its true safety coefficient by harsh crash tests.
As 2018 editions C-NCAP regulations are issued, tightened up experimental condition and higher requirement, to all automobile products
It is all a completely new challenge.In 2018 editions rules, active safety, passive security, pedestrian protecting item and pure electric vehicle are increased
Automobile/mixed power electric car safety test item, and passenger protection aspect is adjusted.To driver and passenger in automobile side
More stringent requirements are proposed for protection during touching.The quality of scaffold car is increased to by new side collision standard by 950kg
1400kg, collision energy have very big promotion, and in addition avoidance height raises 100mm, and part can be absorbed in pervious collision threshold
Energy, present collision are supported mainly by B column substantially, in view of above, on the basis of existing automobile body B rod structure meet side impact
Become extremely difficult.
In current Automobile Body Design there are mainly two types of the modes of automobile body B columnar region enhancing side impact.One is increase B column
Or threshold intensity, optimize B column or threshold and mainly increase B column section product, increase the moment of inertia, it is empty that this will sacrifice part interior of body
Between, HOP ON-CHOP OFF and cost, and the space optimized is extremely limited；Another kind is optimization anti-collision beam structure of car, increases vehicle
Door collision prevention girders sectional area, increases the moment of inertia, but due to the limitation of car door glass surface, the in addition raising of modeling requirement, car door anti-collision
Beam Y-direction space is extremely limited, and the simple width by increasing door anti-collision joist increases the intensity of door anti-collision joist, will greatly increase
Car door cost and weight.Modification reinforces plate thickness or reinforces plate material, increases the utilization rate of high strength steel plate, lightweight is cars on hand
The main trend of body design, but if the utilization rate of pursuit high-strength plate simply, it will for low and middle-end vehicle cost pressure
It is very big.Therefore reality needs to design that a kind of structure is simple, and the Crashworthy plate of installation easy to process is attached on inner plate of car door, is used for
Meet side impact demand after improving side impact region and absorbs bigger collision energy.
Utility model content
The technical problem to be solved by the utility model is to meet new side collision standard, increase in collision energy,
Avoidance height improves side impact performance in the case where raising.
In order to solve the above technical problems, the utility model is in view of the deficiencies of the prior art and defect, passes through and increase side impact plate
Structure carrys out absorbing side impact energy.
The utility model embodiment provides a kind of arrangements for automotive doors with Crashworthy plate, including inner plate of car door, car door anti-collision
Beam and Crashworthy plate, the door anti-collision joist and Crashworthy plate are fixed on the inner plate of car door, the Crashworthy plate and inner plate of car door it
Between be formed with gap, the inner plate of car door is arranged in close to the side of center body pillar in the Crashworthy plate.
Further, multiple pits being recessed to inner plate of car door direction, the multiple pit are formed on the Crashworthy plate
It is attached on the inner plate of car door.
Further, the Crashworthy plate is steel plate, and the Crashworthy plate is with a thickness of 1-1.5mm.
Further, the Crashworthy plate and inner plate of car door are welded to connect.
Further, the gap between the Crashworthy plate and inner plate of car door is 4mm-6mm, for painting electrophoresis liquid into
Enter.
Further, described door anti-collision joist one end and the top of inner plate of car door connect close to the side of body shell fixing end
It connects, the other end is connect at center body pillar with the downside of the inner plate of car door.
Further, the Crashworthy plate is arranged above the door anti-collision joist.
Further, it is additionally provided with location hole and mounting hole on the Crashworthy plate, for positioning and installing Crashworthy plate.
Implement the utility model embodiment, has the following beneficial effects:
(1) the utility model mainly passes through door anti-collision joist and Crashworthy plate while acting on, to guarantee new edition side impact demand.Its
Middle door anti-collision joist main function is that the collision energy in car door region is transmitted to A column and B column or threshold, upper due to barrier walls
Move, B columnar region collision energy gathers increases, therefore newly increases a Crashworthy plate structure in the region, by increase B columnar region car door with
The intensity of side wall lap goes to absorb part side impact energy, prevents internal body by excessive impact.
(2) the utility model crashworthy plate of vehicle door uses high-strength steel sheet, so that Crashworthy plate stiffness and strength greatly improve, side
Face is greatly reduced car door deformation and impact momentum, safety, high reliablity when colliding.
(3) the utility model crashworthy plate of vehicle door structure is simple, light-weight, reduces vehicle body cost, easy to process and assembly.
The installation of the utility model is not related to the change of inner plate of car door other structures, it is only necessary in the region that inner plate of car door and B column are overlapped
Increase solder joint.
