Preferably, described towing hook sleeve pipe front shoe two ends have the first binding face and the second binding face respectively, the described rear longitudinal floor beam shrouding of described first binding face laminating, and described second binding face is fitted the 3rd binding face of described towing hook sleeve pipe rear fixed plate.
Preferably, the area of described first binding face is less than the area of described rear longitudinal floor beam shrouding, and the area of described second binding face equals the area of described 3rd binding face.
Preferably, described kink is flute profile.
Preferably, the both sides of described U-lag have the extension of fitting with described rear longitudinal floor beam.
Preferably, described rear longitudinal floor beam shrouding has multiple installation via hole.
Embodiment of the present utility model utilize towing hook sleeve pipe front shoe, towing hook sleeve pipe rear fixed plate towing hook sleeve pipe is fixed on rear longitudinal floor beam below but not in groove, first this avoid the restriction to fog tail lamp, secondly weld nugget can all be positioned at outside groove, convenient operation.

Detailed description of the invention
With reference to figure 2, the rear longitudinal floor beam 7 in the present embodiment is for having the bathtub construction of groove 8.
With reference to figure 3, the towing hook sleeve pipe front shoe 9 in the present embodiment has U-lag 10, and the both sides of U-lag 10 continue upwards to extend to form two extensions 13.Towing hook sleeve pipe front shoe 9 two ends have the first binding face 11 and the second binding face 12 respectively.
With reference to figure 4, the rear longitudinal floor beam shrouding 14 in the present embodiment has the first via hole 15, also has multiple installation via hole 16.
With reference to figure 5, the towing hook sleeve pipe rear fixed plate in the present embodiment has the second via hole 18, kink 19 and the 3rd binding face 20.Kink 19 is also flute profile.
With reference to figure 6, towing hook sleeve pipe 21 is a tube-like piece, for installing rear towing hook.
With reference to figure 7, in the assembling process of the rear towing hook fixed sturcture of the present embodiment, first, by spot welding by welded together to towing hook sleeve pipe front shoe 9, rear longitudinal floor beam shrouding 14, towing hook sleeve pipe rear fixed plate 17, particularly, towing hook sleeve pipe front shoe 9 two ends weld rear longitudinal floor beam shrouding 14, towing hook sleeve pipe rear fixed plate 17 respectively, and after the first binding face 11 is fitted, longitudinal floor beam shrouding 14, second binding face 12 is fitted the 3rd binding face 20.Then; towing hook sleeve pipe 21 is through after the second via hole 18 of the first via hole 15 of rear longitudinal floor beam shrouding 14, the U-lag 10 of towing hook front shoe 9 and towing hook rear fixed plate 17; towing hook sleeve pipe 21 and rear longitudinal floor beam shrouding 14, towing hook sleeve pipe rear fixed plate 17 are welded to connect in via hole cooperation place, the position carbon-dioxide arc welding of towing hook sleeve pipe 21 with the U-lag 10 of towing hook sleeve pipe front shoe 9 is welded.Like this, towing hook sleeve pipe 21, rear longitudinal floor beam shrouding 14, towing hook sleeve pipe front shoe 9 and towing hook sleeve pipe rear fixed plate 17 form a little assembly.Finally, above-mentioned little assembly is welded to the below of rear longitudinal floor beam 7, makes towing hook sleeve pipe front shoe 9, below that towing hook sleeve pipe rear fixed plate 17 is positioned at rear longitudinal floor beam 7 but not groove 8, and rear longitudinal floor beam shrouding 14 close at least partly after the groove 8 of longitudinal floor beam 7.Visible, whole welding operation without the need to carrying out in groove 8, easy to operate, and fixing rear dragging rhampotheca pipe 21 is positioned at the below of rear longitudinal floor beam 7, without the need to considering fog tail lamp moulding.
Be also shown in from Fig. 7, the area of the first binding face 11 is less than the area of rear longitudinal floor beam shrouding 14, and the area of the second binding face 12 equals the area of the 3rd binding face 20, position can with larger area damped vibration in the wings to make towing hook sleeve pipe 21 like this, and in front owing to need not consider to there is vibration stronger Joint strenght and lighter weight near car body.After having welded, the kink 19 of flute profile, extension 13 are all fitted in the below of rear longitudinal floor beam 7, improve Joint strenght.
Although the utility model is described in conjunction with above embodiment, but the utility model is not defined to above-described embodiment, and only by the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essential idea of the present utility model and scope.
