Description
Technical Field
The utility model belongs to the technical field of automobiles, and particularly relates to an automobile door trim panel structure, an automobile door and an automobile.
Background
With the rapid development of the automobile industry and the increasingly severe industrial situation, the NVH characteristics of automobiles become important indexes for measuring the quality of vehicles, wherein abnormal sounds are particularly important reference sensory indexes when consumers select and use the automobiles, and are intolerable, and can directly influence the quality evaluation of the consumers on the vehicles. The door trim abnormal sound is an important part in the automobile abnormal sound, when a vehicle runs, excitation from a road surface is transmitted to a vehicle body through a chassis and then transmitted to the door trim, if the structural rigidity of the door trim is not designed sufficiently, the vibration transmission sensitivity from a chassis mounting point of the vehicle body to each mounting point of the door trim is too high, the excitation transmitted from the road surface can be amplified, the vibration of the door trim is increased, and the parts collide or rub with each other at the mounting point to generate the abnormal sound. The armrest position is a weak position in the door trim, and is also a position where abnormal noise is most likely to occur, and the structural design of the position needs to be considered.
As shown in fig. 1 and 2, the conventional vehicle door is composed of an upper trim panel 1, an inner buckle box 2, a middle trim panel 3, an armrest 4, a lower trim panel 5, a switch panel 6, a map bag 7, and a speaker cover 8, wherein the inner buckle box 2 is mounted on the upper trim panel 1, the middle trim panel 3, the armrest 4, the map bag 7, and the speaker 8 are mounted on the lower trim panel 5, and the switch panel 6 is mounted on the middle trim panel 3 and the armrest 4. As can be seen from fig. 1 and 2, the armrest 4 does not extend through the entire door trim, but is cut off at the right quarter position, which results in a sudden change in cross section at the cut-off, where the rigidity of the door trim is significantly reduced, and insufficient rigidity amplifies the excitation transmitted from the road surface, and this area is the interface between the components including the center trim 3, the armrest 4, the switch panel 6, and the lower trim 5, and is prone to generate mutual friction or impact noise under excitation of a large excitation load. As shown in fig. 3, the door trim has no supporting pillars in the handrail cut-off region, and the existing supporting pillars 9 are all on the middle trim plate 3 and distributed on the upper part of the middle trim plate 3, and are far from the handrail cut-off position, so that the door trim cannot effectively support the region.
