Technical scheme of the present invention is following: a kind of sedan door trim panel; Has plate body (1); This plate body (1) is through injection mo(u)lding; Front edge, feather edge and the lagging dege of plate body (1) bend continuously, form the preceding flange (1a) of " L " shape, following flange (1b) and back flange (1c), and said back flange (1c) is made up of first straight section (1c 1) and second straight section (1c2); First straight section (1c1) of back flange (1c) is perpendicular with plate body (1); Second straight section (1c2) of back flange (1c) is perpendicular with first straight section (1c1), and the thickness of said second straight section (1c2) equates that with the thickness of plate body (1) thickness of first straight section (1c1) is than the little 0.5-1.5mm of thickness of plate body (1).
The present invention is processed by plastic material; Therefore when the design plastic forming dies; Just plate body structure has been carried out typing and location, that is: the Thickness Design with first straight section of flange behind the plate body must be littler than remainder, and first straight section of flange forms the weakening structure of vehicle door interior trim panel behind the plate body.When the vehicle side collision took place, position of collision was positioned at the car door medium position, trim panel from the middle part to around extend and in car outstanding the time; The tensile force influence that the weakening structure of the vehicle door interior trim panel rear side power that is hit produces, the thin local fracture of distortion earlier makes the rearward position of plate body and door skin break away from; Tensile force has been played the effect that weakens step by step; Impact force obtains buffering, makes the stretched length of salient in car of collision place and protrusion area reduce, and under the influence of weakening structure, makes collision back passenger not pushed by the large tracts of land of trim panel; The probability that comes to harm of the above position of occupant waist reduces like this, has guaranteed passenger's safety.Simultaneously, because the attenuation of flange local thickness behind the trim panel, make the weight saving of vehicle door interior trim panel, tooling cost also reduces relatively.The thickness of flange first straight section is advisable than the little 0.5-1.5mm of thickness of plate body behind the plate body, and thickness disparity is too small, the effect of out of reach reduction; Thickness disparity is excessive, can reduce the intensity of flange behind the plate body, influences the fastness that trim panel and door skin are installed.
The exterior angle of connecting place is a fillet between said first straight section (1c1) and the plate body (1), and interior angle is the right angle.Above structure is utilized the principle of stress concentration right angle frangible, can make when collision place, right angle moment receive forceful action and rupture, thereby plays the effect of damp impacts power, further to reduce the distortion of trim panel, guarantees passenger safety in the car.
The minimum thickness at the interior exterior angle of connecting place is not less than 1/3 of plate body (1) thickness between said first straight section (1c1) and the plate body (1).Above structure is guaranteeing between first straight section and the plate body in the Joint strenght in time to be ruptured in the junction when being collided.
Beneficial effect: the present invention can cushion side collision power through weakening structure is set on trim panel, reduces the vehicle door interior trim panel distortion, guarantees passenger's life security, has characteristics such as design is ingenious, simple in structure, good reliability, transformation is easy, improvement cost is low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
