Description
Technical field
The utility model relates to a kind of automobile door structure, and more particularly, it relates to a kind of door anti-collision joist and strengthens structure.
Background technology
In NCAP evaluation test, vehicle with certain speed impacts obstacle, with the actual conditions of this accident simulation.NCAP adopts the injury values of the dummy laid in crashing vehicle to evaluate the safety performance of new car, and dummy's injury is lower, and the safety performance of vehicle is higher.In side collision, the survival space of dummy is very little, the distance of general B post distance front-row seats only has 60mm ~ 100mm, so the intensity of side key structure is very important, the rigidity strengthening side body structure makes key structure have rational deformation pattern to be the emphasis that side collision body structure designs simultaneously.In side collision process, the injury of dummy is mainly derived from car door and B post, general car door adopts the form of installing collision prevention girders to strengthen its rigidity, mostly collision prevention girders mounting bracket of the prior art is the effect only serving installation, does not play the effect strengthened collision prevention girders Y-direction.Publication number is that the patent of invention of CN103195339A discloses a kind of bus door retraining side impact distortion on July 10th, 2013, comprise car door body, trim panel, described car door body is made up of outside plate, collision prevention girders, brace panel, inner panel, outer plate edge is provided with outside frame, described inner panel is fixed on outside frame, inner panel is provided with a High-strength stretching-resistantgeogrid board fiber board of fitting with it, this stretch-proof board fiber board is fixed on outside frame together with inner panel, and described trim panel is fixed on the outside of stretch-proof board fiber board.The present invention has stronger anti-side and touches ability, avoids because interior space is subject to the feature threatened to the life security of occupant that crushes causes.But collision prevention girders and inner panel are just connected as a single entity by brace panel by this invention, improve car door intensity thus strengthen anti-side and touch ability, brace panel there is no the structure being provided with specially and helping collision prevention girders Y-direction and strengthen.
Utility model content
Existing collision prevention girders is strengthened structure and is not provided with the structure being beneficial to collision prevention girders Y-direction and strengthening specially, more just strengthen structure by collision prevention girders and collision prevention girders and other automobile door structure coupled together play booster action, therefore often structure is more complicated more takes up space, for overcoming these defects, the utility model provide a kind of use more simple structure just can obtain collision prevention girders Y-direction strengthen door anti-collision joist strengthen structure.
The technical solution of the utility model is: a kind of door anti-collision joist strengthens structure, comprise collision prevention girders, collision prevention girders is fixedly arranged on inner plate of car door, this structure also comprises collision prevention girders brace panel, collision prevention girders brace panel is fixedly arranged on inner plate of car door, collision prevention girders is fixedly arranged on collision prevention girders brace panel, and collision prevention girders brace panel comprises Y-direction bearing surface and collision prevention girders stationary plane, Y-direction bearing surface and collision prevention girders stationary plane angle structure being solidly fixed each other.Collision prevention girders brace panel had both played and had connected inner plate of car door and crashproof beam action, the effect of reinforced rib is played again by Y-direction bearing surface, before collision prevention girders, the distortion of car door Y-direction is stopped in advance when there is side impact, absorb a part of impact kinetic energy, make collision prevention girders brace panel and collision prevention girders can have echelon ground energy-absorbing, thus strengthen door side-collision-prevention performance, improve vehicle safety.
As preferably, Y-direction bearing surface and collision prevention girders stationary plane are formed in one structure.Integrated collision prevention girders brace panel processing is more convenient, and material is more homogeneous, and intensity is more guaranteed.
As preferably, inner plate of car door is provided with frame, and frame is provided with step, Y-direction bearing surface and collision prevention girders stationary plane be welded on respectively form step two terraces on.Collision prevention girders brace panel is designed to top bar Matching installation preferably with inner plate of car door frame, can fixing on inner plate of car door of convenient and swift realization with welding manner.
The beneficial effects of the utility model are:
Improve car door anti-side and touch performance.The utility model adds the support to collision prevention girders Y-direction by collision prevention girders brace panel, reduces speed and deflection that collision prevention girders invades in car, thus improves vehicle safety.
Structure is simple, is convenient to processing and assembling.Setting of the present utility model does not relate to the change of its week edge pieces structure, only needs and increases by two solder joints between inner plate of car door, changes less to technique.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of using state schematic diagram of the present utility model.
In figure, 1-inner plate of car door, 2-collision prevention girders, 3-collision prevention girders brace panel, 4-Y-direction bearing surface, 5-collision prevention girders stationary plane.
Detailed description of the invention
Below in conjunction with accompanying drawing specific embodiment, the utility model is described in further detail.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of door anti-collision joist strengthens structure, comprise collision prevention girders 2, collision prevention girders 2 is fixedly arranged on inner plate of car door 1, this door anti-collision joist is strengthened structure and is also comprised collision prevention girders brace panel 3, collision prevention girders brace panel 3 is fixedly arranged on inner plate of car door 1, collision prevention girders 2 is welded on collision prevention girders brace panel 3, collision prevention girders brace panel 3 comprises Y-direction bearing surface 4 and collision prevention girders stationary plane 5, Y-direction bearing surface 4 and collision prevention girders stationary plane 5 angle structure being solidly fixed each other, Y-direction bearing surface 4 and collision prevention girders stationary plane 5 angle are about 90 °, and rounding off between the two.Y-direction bearing surface 4 and collision prevention girders stationary plane 5 are shaping with same steel plate integrated punching.Inner plate of car door 1 is provided with frame, and frame is provided with step, and the angle of Y-direction bearing surface 4 and collision prevention girders stationary plane 5 is provided with solder joint, and such Y-direction bearing surface 4 and collision prevention girders stationary plane 5 can be welded on two terraces of formation step respectively.
In side collision process, because Y-direction bearing surface 4 can first resist car door to internal strain before collision prevention girders 2, absorb a part of impact kinetic energy, such impulsive force weakens when being delivered to collision prevention girders 2 greatly, whole collision prevention girders 2 reduces to the enterolithic speed of car, and deflection there has also been and greatly reduces, and the intrusion volume bottom car door and the force value suffered by dummy's basin bone reduce, the overall score of side impact improves, and car load safety assessment score also can increase.
