The invention discloses a vehicle threshold mounting method and a vehicle threshold structure thereof. The mounting method comprises the following steps: providing a threshold inner plate being a steel plate sheet metal part provided with an upper section, a middle section and a lower section, the middle section being formed between the upper section and the lower section, and the middle section being connected with a vehicle body floor in a spot welding mode; forming a vehicle body framework structure; providing a threshold outer plate, installing the threshold outer plate transversely alongthe vehicle, and fixedly connecting the top wall of the threshold outer plate with the upper section; and fixedly connecting the side wall, close to the threshold inner plate, of the threshold outer plate with the lower section. Compared with the prior art, by means of the mode that the threshold inner plate of the steel plate is connected with the threshold outer plate of the aluminum profile andthe spot welding framework of the threshold inner plate and the vehicle body, the precision requirement can be met without other supports or reinforcing pieces, the overall structure is simple, partsdo not need to be polished and adjusted, and the matching performance with peripheral parts is good; and the sealing problem of the seam allowance surface of the vehicle door is effectively solved.

    本发明公开了一种车辆门槛的安装方法及其车辆门槛结构,该安装方法包括以下步骤:提供一门槛内板,门槛内板为设置有上段、中段和下段的钢板钣金件,中段形成于上段与下段之间,中段与车身地板通过点焊方式进行连接,形成车身骨架结构;提供一门槛外板,门槛外板沿车辆横向安装,门槛外板的顶壁与上段固定连接;门槛外板靠近门槛内板的侧壁与下段固定连接。本发明相对于现有技术,通过钢板的门槛内板与铝型材的门槛外板连接的方式以及门槛内板与车身的点焊骨架,不需采用其他的支撑或加强件即可满足精度要求,整体结构简单,零件无需打磨调整,且与周边零件匹配性较好,有效地解决了车门止口面的密封问题。
