The invention provides a tow hook mounting structure, and the structure comprises a through hole formed in the groove bottom of a groove-shaped front anti-collision beam and used for a tow bar to penetrate through; a nut seat is arranged behind the through hole, an expanding unit is adjacently arranged in front of the threaded section of the tow bar in the length direction of a vehicle, and the threaded section of the tow bar is screwed into the nut seat; the rear end of the expanding unit and the nut seat extrude to drive the front end of the expanding unit to open, and the front end of the expanding unit and the groove bottom of the front anti-collision beam form limiting fit for limiting forward displacement of the tow bar relative to the front anti-collision beam after the front end ofthe expanding unit is opened. A common threaded pipe mounting structure is canceled, so the compression space of the energy absorption box is prevented from being occupied by an overlong rigid threaded pipe structure, and meanwhile, one nut seat is reduced on the basis of the previous application scheme of the applicant, so only one nut seat needs to be aligned when the tow hook is mounted, so the situation of mutual interference when a plurality of nut seats are mounted in a matched manner is avoided.

    本发明提供了一种拖车钩安装结构,包括槽型的前防撞梁的槽底开设的供拖车杆穿过的通孔,通孔后方设置有螺母座,车长方向上拖车杆的螺纹段前方紧邻设置有扩胀单元,拖车杆的螺纹段旋入螺母座后,扩胀单元后端与螺母座挤压驱使扩胀单元前端张开,扩胀单元前端张开后与前防撞梁的槽底构成限制拖车杆相对于前防撞梁向前位移的限位配合。取消了常见的螺纹管安装结构,这样便能避免过长的刚性螺纹管结构挤占吸能盒的压缩空间,同时在本申请人的在先申请的方案的基础上减少了一个螺母座,使得拖车钩安装时只需对准一个螺母座即可,避免多个螺母座配合安装时出现互相干涉的情况。
