Abstract
The utility model discloses the two crash-proof pole structure of a kind of automobile front door, comprise the upper crash bar of layout side by side up and down and lower crash bar, the rear and front end of described two crash bars is welded and fixed respectively by front mounting bracket and rear mounting bracket and inner plate of car door.This pair of crash-proof pole structure can be played a supporting role when vehicle generation side collision, better protects occupant safety.
Description
Technical field
The utility model relates to arrangements for automotive doors parts, is specially the two crash-proof pole structure of a kind of automobile front door.
Background technology
The European ENCAP(Europe new car evaluation of 2015 editions) will larger variation be there is, wherein the obstacle quality of side crash is increased to 1300kg by 950kg, and obstacle shape there has also been larger change.The speed of Collision of Flank Pole brings up to 32 kilometers/hour by 29 kilometers/hour.In a word, the ENCAP of 2015 editions will be more strict, and this just has higher requirement to vehicle body side structure.
Automotive front door anti-collision beam many employings single tube structure (as accompanying drawing 1) domestic at present, in this kind of structure, a high tensile steel tube 9 is connected on inner plate of car door by strut member.But this structure is when 2015 editions European ENCAP side collisions and Collision of Flank Pole are analyzed, and the flexing resistance of crash bar is poor, the intrusion volume of car door is comparatively large, cannot meet the demands.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile front door two crash-proof pole structure, plays a supporting role, better protect occupant safety when vehicle generation side collision.
The two crash-proof pole structure of automobile front door described in the utility model, comprises the upper crash bar of layout side by side up and down and lower crash bar, and the rear and front end of described two crash bars is welded and fixed respectively by front mounting bracket and rear mounting bracket and inner plate of car door.
Further, the outside face of described upper and lower crash bar is bonding with car door skin.
Further, the described front mounting bracket that is welded and fixed with inner plate of car door and rear mounting bracket are equipped with two deep-slotted chip breakers, the deep-slotted chip breaker that the front end of described two crash bars is corresponding with on front mounting bracket is respectively welded and fixed, and the deep-slotted chip breaker that the rear end of two crash bars is corresponding with on rear mounting bracket respectively is again welded and fixed.
Further, described front mounting bracket and rear mounting bracket are respectively equipped with some reinforced ribs.
Further, described front mounting bracket and rear mounting bracket also offer knock hole respectively.
The utility model, by arranging the crash bar of two high strength at Qianmen, when vehicle generation side collision, effectively can share the impact that car door is subject to, and keeps crew module's structure integrity, reduces car door distortion intrusion volume, protection occupant safety.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and following examples, only for explaining the utility model, do not form the restriction to the utility model protection domain.
The two crash-proof pole structure of automobile front door as shown in Figure 2, Figure 3, Figure 4, comprises the upper crash bar 1 of layout side by side up and down and lower crash bar 2, and the rear and front end of described two crash bars is welded and fixed with inner plate of car door 5 respectively by front mounting bracket 3 and rear mounting bracket 4.Described two crash bars adopt ultra-high-tensile steel pipe to make, and forward and backward mounting bracket is punch forming sheet metal component.
Described front mounting bracket 3 and rear mounting bracket 4 are welded and fixed by spot welding and inner plate of car door.Described front mounting bracket and rear mounting bracket are equipped with two deep-slotted chip breakers; the front end of two crash bars welds corresponding being welded and fixed with the deep-slotted chip breaker 301 on front mounting bracket by protecting respectively, and the rear end of two crash bars welds corresponding being welded and fixed with the deep-slotted chip breaker 401 on rear mounting bracket by protecting again respectively.The outside face of described upper and lower crash bar is bonding with car door skin.
Reinforced rib 402 on reinforced rib 302 on front mounting bracket and afterwards mounting bracket plays the effect strengthening mounting support structure intensity, locates when the knock hole 303 on front mounting bracket and the knock hole 403 on rear mounting bracket are for assembling.
Fig. 5 is Qianmen and AE-MDB (the Advanced European Movable Deformable Barrier) projection view in Y-direction (overall width direction).When colliding, car door 6 first contacts with the starting section 8 of mobile obstacle, now because lower crash bar 2 overlaps in Y-direction with the starting section of mobile obstacle, first contacting, playing main supporting role both when colliding.Then go up crash bar 1 to contact with the rear cross section 7 of mobile obstacle with lower crash bar 2, jointly car door is played a supporting role, the integraty of crew module can be ensured, better protect occupant.
