Technical scheme of the present invention is as follows: a kind of sedan door trim panel, there is plate body (1), this plate body (1) is by injection mo(u)lding, the front edge of plate body (1), feather edge and lagging dege bend continuously, form the front flange (1a) of " L " shape, lower flange (1b) and rear flange (1c), described rear flange (1c) is made up of the first straight section (1c 1) and the second straight section (1c2), first straight section (1c1) of rear flange (1c) is perpendicular with plate body (1), second straight section (1c2) of rear flange (1c) is perpendicular with the first straight section (1c1), the thickness of described the second straight section (1c2) equates with the thickness of plate body (1), the little 0.5-1.5mm of thickness of the Thickness Ratio plate body (1) of the first straight section (1c1).
The present invention is made up of plastic material, therefore in the time of design plastic forming dies, just plate body structure has been carried out to sizing and location, that is: must be less than remainder by the Thickness Design of the first straight section of flange after plate body, after plate body, the first straight section of flange forms the weakening structure of vehicle door interior trim panel.In the time there is vehicle side collision, position of collision is positioned at car door medium position, trim panel extends from middle part to surrounding and to outstanding in car time, the tensile force impact that the weakening structure of the vehicle door interior trim panel rear side power that is hit produces, thinner place is first out of shape fracture, rearward position and the door skin of plate body are departed from, tensile force is played to the effect weakening step by step, impact force is cushioned, the salient of collision place is reduced to stretched length and protrusion area in car, after making to collide under the impact of weakening structure, passenger is not pushed by the large area of trim panel, the probability that the above position of occupant waist comes to harm like this reduces, ensure passenger's safety.Meanwhile, due to the attenuation of flange local thickness after trim panel, make the weight saving of vehicle door interior trim panel, tooling cost also reduces relatively.After plate body, the little 0.5-1.5mm of thickness of the Thickness Ratio plate body of flange the first straight section is advisable, and thickness disparity is too small, the effect that out of reach weakens; Thickness disparity is excessive, can reduce the intensity of flange after plate body, affects the fastness that trim panel and door skin are installed.
Between described the first straight section (1c1) and plate body (1), the exterior angle of connecting place is fillet, and interior angle is right angle.Above structure utilizes stress to concentrate the principle of right angle frangibility, and can make to collide time, right angle place moment be subject to forceful action and ruptures, thereby plays the effect of damp impacts power, further to reduce the distortion of trim panel, guarantees passenger inside the vehicle's safety.
Between described the first straight section (1c1) and plate body (1), in connecting place, the minimum thickness at exterior angle is not less than 1/3 of plate body (1) thickness.Above structure is guaranteeing between the first straight section and plate body, in Joint strenght, can to make junction rupture in time in the time being collided.
Beneficial effect: the present invention, by weakening structure is set on trim panel, can cushion side collision power, reduces vehicle door interior trim panel distortion, ensures passenger's life security, has the features such as design is ingenious, simple in structure, good reliability, transformation is easy, improvement cost is low.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As depicted in figs. 1 and 2, the trim panel of sedan door has plate body 1, and the moulding of this plate body 1 is same as the prior art, does not repeat at this.Plate body 1 is by injection mo(u)lding, and the front edge of plate body 1 bends continuously, forms the front flange 1a of " L " shape.The feather edge of plate body 1 bends continuously, forms the lower flange 1b of " L " shape.The lagging dege of plate body 1 bends continuously, forms the rear flange 1c of " L " shape.Described front flange 1a, lower flange 1b are connected successively with rear flange 1c, and front flange 1a, lower flange 1b and rear flange 1c are positioned at the same side of plate body 1.
