Tow hook mounting structure

Abstract

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.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a tow hook installation structure. Background technique [0002] The tow hook is the trailer and towing device of the car. Many brands of cars have a tow hook when they leave the factory. The car tow hook has become a must-have part of the car. [0003] The applicant's prior application publication number is CN110962513A, which discloses a trailer coupler nut box, which cancels the common nut tube structure by setting the front and rear two nut seats, so as to avoid the threaded tube arranged in front of the energy absorbing box. Occupying the compression space of the energy-absorbing box ensures that the energy-absorbing box can fully compress and absorb energy when the vehicle is hit. Yet in this application, there are front and rear nut seats, which need to be threaded with the front and rear two nut seats when screwed into the tow hook. When the tow hook is screwed into the front n...

Problems solved by technology

Yet in this application, there are front and rear nut seats, which need to be threaded with the front and rear two nut seats when screwed into the tow hook. When the tow hook is screwed into the front nut seat, it continues to screw forward. When the threaded end of the hook reaches the rear nut seat, it is easy to produce a position deviation. At this time, idle rotation will occur on the rear nut seat. During the rotation of the tow hook, the tow hook extends into the front nut seat and its end fails to rotate in time. Insert the rear nut seat, so that the end of the tow hook will press against the rear nut seat. It is necessary to repeatedly unscrew the tow hook and screw it in to align with the rear nut seat. When the rear nut seat is pressed, the position of the rear nut seat will be shifted, which will further affect the screwing in of the tow hook
