Description
Technical field
The utility model relates to technical field of automobile parts, especially relates to a kind of bump-proof rod for automobile door.
Background technology
Universal along with automobile, the safety of automobile receives publicity day by day, and bump-proof rod for automobile door is the strength and stiffness in order to strengthen car door, and the safety performance of auto against and car door design by anti-impouring ability when colliding and develop.At present; there is following problem in bump-proof rod for automobile door: (1) is when the steel plate structure type of front and back door employing high strength; because steel plate cross-sectional area is larger; when being subject to side impact; can effective absorbing forces of impact by bus personnel are protected; but because steel plate cross-sectional area is comparatively large, increase mould development cost and car door weight.(2) when front and back door adopts single crash bar to arrange, crash bar cross section is less, resists collision energy limited.And existing car door anti-collision mechanism is flush type, and energy-absorbing effect is poor.
Summary of the invention
For the shortcoming that above prior art exists, the utility model provides the bump-proof rod for automobile door that a kind of structure is simple, energy-absorbing effect good, impact resistant capability is strong.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: provide a kind of bump-proof rod for automobile door, it is characterized in that: comprise crash bar and four breeches pipes, described crash bar has four, and be bending arc, one end of four described crash bars is connected in four bifurcateds of described four breeches pipes, in X-type, and four described crash bars are bending to the same side, the other end of crash bar connects a supporting seat respectively, described four breeches pipes are positioned at described crash bar bending be fixedly connected with a Crashworthy plate back through spring.
Further, described supporting seat comprises base plate and is positioned at the mounting hole seat on base plate, and described base plate is provided with bolt hole, and one end that crash bar described in every root is connected with described supporting seat is installed with a construction section, described construction section is parallel to the base plate of described supporting seat, and can insert described mounting hole seat.
Further, described base plate is provided with four described bolts hole, for supporting seat is fixed on car body.
Further, the cross-sectional plane of described crash bar is oblong or ellipse.
Further, described crash bar is provided with reinforced rib along its length.
Further, not connected between four pipe manifolds of described four breeches pipes.
The advantage that the utility model has and beneficial effect are: be provided with four crash bars, and every root crash bar is bending flat tube shape, can effectively save arrangements for automotive doors inner space; One end of crash bar connects four breeches pipes, other end connecting support seat, thus crash bar is fixed, and in installation process, the bending direction of four crash bars is consistent, can play good impact resistance effect when receiving collision, crash bar is provided with reinforced rib, further strengthens the impact resistant capability of crash bar; Four breeches pipes are positioned at bending reverse of crash bar, namely near car door side, are installed with a Crashworthy plate by spring, when car door receives shock, first act on this Crashworthy plate, and then Compress Spring, spring plays the effect absorbing impact, makes this side door beams have good energy-absorbing effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1-Figure 3, the utility model provides a kind of bump-proof rod for automobile door, comprises four crash bars 1 and four breeches pipes 6.Article four, crash bar 1 is bending arc, and crash bar 1 is flat tube, and its cross-sectional plane is oval.Four breeches pipes 6 have four pipe manifolds, not connected between four pipe manifolds.Wherein one end of four crash bars 1 is connected in four bifurcateds of four breeches pipes 6, and in X-type, and four crash bars 1 are bending to the same side, make overall in bowl-shape.The other end of crash bar 1 connects a supporting seat respectively, four breeches pipes 6 are positioned at crash bar 1 bending be fixedly connected with a Crashworthy plate 7 back through spring 8.
Wherein, the mounting hole seat 4 that supporting seat comprises base plate 3 and is positioned on base plate 3, base plate 3 is provided with four screws 5, for being fixedly connected with car body.One end that every root crash bar 1 is connected with supporting seat is installed with a construction section 2, and construction section 2 is parallel to the base plate 3 of supporting seat, and can insert in mounting hole seat 4.
In order to strengthen the intensity of side door beams further, every root crash bar 1 is also provided with reinforced rib 9 along its length, and respectively establishes a reinforced rib 9 in the both sides, front and back of crash bar 1.
Crash bar 1, four breeches pipe 6, supporting seat all adopt high strength steel material to make.
In the process of installing, first four crash bars 1 are inserted in four bifurcateds of four breeches pipes 6 respectively, make four crash bar 1 bending directions consistent, one end crash bar 1 being installed with construction section 2 is inserted in the mounting hole seat 4 of supporting seat, Crashworthy plate 7 is made to be positioned at vehicle door side, supporting seat is bolted on the car body at arrangements for automotive doors place, when car door receives shock, first Crashworthy plate 7 is contacted, Crashworthy plate 7 is connected with spring 8, spring 8 can absorb a part of Impact energy, afterwards impact remake with four breeches pipes 6, because crash bar 1 is bending, thus greatly enhance impact resistant capability, in addition because crash bar 1 is provided with reinforced rib 9, thus impact resistant capability is strengthened further, can the safety of available protecting occupant.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
