The invention belongs to the technical field of automobile parts, and particularly relates to a front upper fork arm and automobile body connecting structure and an automobile, the front upper fork arm and automobile body connecting structure comprises a nut, a connecting bolt and a clamping structure fixedly arranged on the automobile body, the nut comprises a square boss and a disc boss, the square boss is fixedly arranged on the end face of the disc boss, and the clamping structure comprises a mounting plate; the surface normal of the mounting plate coincides with the central axis of the mounting through hole, a guide groove is formed in the upper portion of the mounting plate, the square boss is clamped in the guide groove, the disc boss is located between the mounting plate and the vehicle body, and the connecting bolt penetrates through the mounting through hole to be in threaded connection with the nut. The invention aims to provide a nut assembly for a vehicle body, which is characterized in that the nut consisting of a square boss and a disc boss is matched with a clamping structure provided with a guide groove, so that on the basis of adopting an independent nut design and avoiding the problem of difficulty in repairing or higher repairing cost after a thread is damaged, the nut is matched with the clamping structure on the vehicle body, and the nut assembly is convenient to disassemble and assemble. Therefore, the subsequent installation of the connecting bolt is more convenient.

    本发明属于汽车零部件技术领域,具体涉及一种前上叉臂与车体连接结构及车辆,包括螺母、连接螺栓和固定设置在车体上的卡设结构,螺母包括方形凸台和圆盘凸台,方形凸台固定设置于圆盘凸台的端面,卡设结构包括安装板,安装板的面法线与安装过孔的中轴线重合,安装板的上部开设有导向槽,方形凸台卡设在导向槽内,圆盘凸台位于安装板和车体之间,连接螺栓穿过安装过孔与螺母螺接。其目的是:通过由方形凸台和圆盘凸台构成的螺母与开设有导向槽的卡设结构的相互配合,在采用独立螺母设计,避免了当螺纹损坏后,存在不易返修或返修成本较高的问题的基础上,利用螺母与车体上的卡设结构的相互配合,完成螺母的固定,后续的连接螺栓安装更加方便。
