The invention discloses a power centralized type motor train unit entrance door. The door comprises an inner door plate, an outer door plate and a door framework connected with the inner door plate and the outer door plate, the door framework comprises a plurality of beam parts and a frame, door plate parts are defined between the beam parts and/or between the beam parts and the frame, a heat preservation layer and an aluminum honeycomb plate layer are sequentially arranged between the inner door plate and the outer door plate where the door plate part is located, each beam part comprises an upper beam and a lower beam, and the heat preservation layer is arranged between the upper beam and the lower beam. The heat preservation layer and the aluminum honeycomb plate layer are arranged between the inner door plate and the outer door plate, so that the automobile door has the heat preservation performance, the weight of the automobile door cannot be increased due to the arrangement of thealuminum honeycomb plate, meanwhile, a cavity is formed between the hollow structure of the aluminum honeycomb plate and the outer door plate, and the effects of heat insulation and sound insulationare achieved to a certain extent; and through the arrangement of the door framework, the aluminum honeycomb plate is of the hollow honeycomb structure, the lateral strength of the door can be improved, and when the outer portion of the outer door plate is stressed, the door is not prone to deforming inwards.

    本发明公开了一种动力集中型动车组入口门体,包括内门板、外门板和连接内门板和外门板的门骨架,所述门骨架包括若干梁部和边框,所述梁部与梁部和/或梁部与边框之间限定为门板部,所述门板部所在的内门板与外门板之间依次设为保温层和铝蜂窝板层,所述梁部包括上梁和下梁,所述上梁和下梁之间设有保温层;通过在内外门板间设置保温层和铝蜂窝板层,使得车门门体具备保温性能,铝蜂窝板的设置使得车门的重量不会增加,同时铝蜂窝板的镂空结构与外门板间形成空腔,在一定程度上起到了隔热和隔音的效果,通过门骨架的设置,使得整个门体结构强度足够,铝蜂窝板的镂空蜂窝结构,也是能增加门体侧向强度,在外门板外部受力时,不易向内发生形变。
