Abstract
The invention relates to a vehicle door with a side impact energy absorbing structure. The vehicle door has a door interior trim panel. The back of the door interior trim panel is provided with a side impact energy absorbing element which is an integral element formed by injection molding. The main body of the side impact energy absorbing element is a trapezoidal frame and reduces from bottom to top. The bottom of the main body is a mounting surface which is arranged to be jointed with the door interior trim panel. One side of a top end of the trapezoidal frame of the side impact energy absorbing element is provided with a horizontal U-shaped structure. In the invention, an interior trim system is optimized through a simple structure, and the energy absorbing structure adopts the frame which has a small top and a big bottom and is light in weight and susceptible to breakage during side impact to ensure complete absorption of energy during the whole process of the side impact and the horizontal U-shaped structure for the trapezoidal frame to contact compact energy and cushion part of the energy and pass the energy to the frame below, thereby ensuring the safety of crew members to maximum and improving the side impact performance of vehicles.
Description
Technical field
The invention belongs to the vehicle body technical field, be specifically related to car door side impact energy-absorbing technology.
Background technology
Along with the increase of world car recoverable amount and the continuous increase of Road Traffic Injury, the crashworthiness energy-absorbing has become an important ring of automobile design process, how to relax the impact of the outer bound pair person, legislative control on safety is to the side impact demands for higher performance of vehicle, the energy absorption mechanism of superior performance can be improved the side impact performance of automobile effectively, and common door trim board is not adorned side impact energy-absorbing structure.For satisfying side impact test and crew member's security needs, generally in the designing car door internal decoration plate, consider side impact energy-absorbing, directly on the Door Trim body, design, it is simple in structure, layout is easy, processing is inconvenient, and energy-absorbing effect is poor, and the energy-absorbing that has higher requirements then is difficult to satisfy.
Summary of the invention
Be the laws and regulations requirement that satisfies increasingly stringent and the exploitation theory of consumer uppermost; improve the side impact performance of car load; be unlikely to too high again to the designing requirement of Door Trim; simultaneously; the weight of the least possible increase car door, cost-cutting the invention provides a kind of car door with side impact energy-absorbing structure as far as possible; guarantee that whole side impact process can absorb energy fully, farthest protects crew member's safety.
Technical scheme of the present invention is as follows:
A kind of car door with side impact energy-absorbing structure, it has vehicle door interior trim panel, at the trim panel back side side impact energy-absorbing spare is installed, described side impact energy-absorbing spare is the single piece of an injection mo(u)lding, main body is a ladder-shaped frame, the bottom is big, receives for a short time gradually to the top, and the attachment face of fitting and installing with vehicle door interior trim panel is arranged at the bottom.
Ladder-shaped frame top one side of described side impact energy-absorbing spare also has a horizontal U type structure.
Described side impact energy-absorbing spare is installed on the trim panel by cooresponding claw clamping on hole clipping on the attachment face and the vehicle door interior trim panel.
Technique effect of the present invention: the present invention is by better simply structure; realized the optimization of interior decoration system; the endergonic structure connection and reasonable arrangement; technology is simple; cost is low; adopt up-small and down-big Frame Design on the structure; in light weight; framework fractures easily during side impact, guarantees that whole side impact process can absorb energy fully, has further also designed horizontal U type structure on ladder-shaped frame; an elder generation's contact-impact energy and a buffering part; simultaneously transfer of energy is given the framework of bottom, thereby farthest protected crew member's safety, improve the side impact performance of vehicle.
Description of drawings

Fig. 2 is the birds-eye view of this side impact energy-absorbing part;
Fig. 3 is the A-A section-drawing of Fig. 2;
Fig. 4 is the B-B section-drawing of Fig. 2;
Fig. 5 is the block diagram of side impact energy-absorbing spare.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
Referring to Fig. 1, the car door that originally has side impact energy-absorbing structure has vehicle door interior trim panel 1 and side impact energy-absorbing spare 2, and the material of side impact energy-absorbing spare is PP, directly injection mo(u)lding, and technology is simple.Referring to Fig. 2, Fig. 3, Fig. 4 and Fig. 5, the main body of side impact energy-absorbing spare 2 is ladder-shaped frames 22, the bottom is big, receive gradually to the top little, the attachment face 21 that the bottom is and vehicle door interior trim panel fit to be installed, attachment face 21 is attached to the back side of door internal decoration plate 1, four angles of attachment face are provided with mounting hole 24, four claws that correspondence position on the vehicle door interior trim panel 1 also carries snap in the mounting hole 24, and side impact energy-absorbing spare 2 just is fixed to the back side of vehicle door interior trim panel 1.Be provided with horizontal U type structure 23 on the attachment face top by a side.
When car door is received side impact, side impact energy-absorbing spare top horizontal U type structure 23 contact energy earlier, a buffering part, and apace with the ladder-shaped frame 22 of transfer of energy to the bottom, because Frame Design in echelon, energy is delivered to trapezoidal narrow limit by trapezoidal broadside, is out of shape fracture on trapezoidal narrow limit and attachment face 21 intersections behind the frame stressing, thereby reaches the effect of energy-absorbing.
Claims (3)
1, a kind of car door with side impact energy-absorbing structure, it has vehicle door interior trim panel, it is characterized in that: side impact energy-absorbing spare is installed at the trim panel back side, described side impact energy-absorbing spare is the single piece of an injection mo(u)lding, main body is a ladder-shaped frame, the bottom is big, receives for a short time gradually to the top, and the attachment face of fitting and installing with vehicle door interior trim panel is arranged at the bottom.
2, the car door with side impact energy-absorbing structure according to claim 1 is characterized in that: ladder-shaped frame top one side of described side impact energy-absorbing spare also has a horizontal U type structure.
