Description
技术领域 technical field
本实用新型涉及门结构领域,具体为一种双层门框结构,尤其适用于轨道交通司机门结构中。 The utility model relates to the field of door structures, in particular to a double-layer door frame structure, which is especially suitable for the driver's door structure in rail transit.
背景技术 Background technique
现有不锈钢司机室门框大体由直边型材和圆角型材组成的单框结构,直边型材依次通过圆角型材拼接或者焊接在一起。这种方式形成的门框结构需要的焊接量较大,容易导致与外侧蒙皮贴合面平面度较差,同时由于门角大多处于焊接区域,容易导致应力集中。 The existing stainless steel driver's cab door frame is generally a single-frame structure composed of straight-side profiles and rounded-corner profiles, and the straight-side profiles are spliced or welded together through rounded-corner profiles in turn. The door frame structure formed in this way requires a large amount of welding, which may easily lead to poor flatness of the bonding surface with the outer skin. At the same time, since most of the door corners are in the welding area, it may easily lead to stress concentration.

The rear door column, and the door upper beam fixedly connected with the outer wall surface of the top of the door inner frame; the threshold, the front door column, the door upper beam and the rear door column are sequentially spliced to form a closed structure.
优选地,所述双层门框为司机室双层门框,所述后门立柱为阶梯状,该阶梯状为司机室和侧墙提供过渡区域。 Preferably, the double-layer door frame is a driver's cab double-layer door frame, and the rear door column is stepped, and the stepped shape provides a transition area between the driver's cab and the side wall.
所述前门立柱为折弯件,由此在安装蒙皮时可以保证蒙皮外表面的平面度。 The front door column is a bent part, so that the flatness of the outer surface of the skin can be guaranteed when the skin is installed.
为了方便内门框和外门框的固定,所述门内框外壁面上开有用于与门外框固定相连的预留孔。 In order to facilitate the fixing of the inner door frame and the outer door frame, the outer wall of the inner door frame is provided with a reserved hole for being fixedly connected with the outer door frame.
更优选地,所述门内框的拐角处为弧线过渡结构,由此可以进一步消除应力集中现象。 More preferably, the corners of the door inner frame are arc transition structures, so that stress concentration can be further eliminated.
藉由上述结构,本实用新型的双层门框结构由闭合型材和折弯件拼焊形成的外门框和整体冲压形成的内门框两部分组成,内外框之间通过内门框上的预留孔塞焊连接。外门框组成中的后门立柱阶梯形状为司机室过渡到车体侧墙提供了过渡区域。本实用新型使用高强度的大断面闭合型材和折弯件组成外门框结构保证结构的整体强度,进而保证后续侧墙蒙皮的整体平面度。 With the above structure, the double-layer door frame structure of the present invention is composed of two parts: the outer door frame formed by the closed profile and the bending parts, and the inner door frame formed by integral stamping. Solder connection. The stepped shape of the rear door pillar in the composition of the outer door frame provides a transition area for the transition from the driver's cab to the side wall of the body. The utility model uses high-strength large-section closed profiles and bending parts to form an outer door frame structure to ensure the overall strength of the structure, and further ensure the overall flatness of the subsequent side wall skin.
与现有技术相比,本实用新型的有益效果是:本实用新型双层门框结构结构实现了结构的功能,有效减小门角应力集中,降低了装配要求,提高了产品质量、生产的效率和设备的利用率。 Compared with the prior art, the beneficial effect of the utility model is that the double-layer door frame structure of the utility model realizes the function of the structure, effectively reduces the stress concentration of the door corner, reduces assembly requirements, and improves product quality and production efficiency and equipment utilization.
