Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2023-0140976 filed in the Korean Intellectual Property Office on October 20, 2023, and Korean Patent Application No. 10-2024-0127199 filed in the Korean Intellectual Property Office on September 20, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to a vehicle body, and more particularly to a towing hook assembly installed on a bumper beam of a vehicle body. Background Art

[0004] Generally, a bumper unit of a vehicle is configured to improve the safety of passengers by absorbing physical impact during a collision and minimizing damage to vehicle body components. The bumper unit of a vehicle has a bumper beam disposed in a vehicle width direction.

[0005] Towing hooks can be mounted on these bumper beams. In one example, the towing hooks can be provided as eyebolt types that can engage with towing tubes fixed on the bumper beams.

[0006] In another example, the towing hook may be a lug-type towing hook protruding from a bumper skin of a bumper beam. Such a lug-type towing hook is applied to the front of the vehicle to meet the recently strengthened off-road towing load conditions. In addition, the lug-type towing hook may be applied to the front of the vehicle together with the front bumper to protect the front of the vehicle.

[0007] In this case, the lug-type towing hook protrudes forward to a certain extent to avoid interference with the towing cable and the front bumper.

[0008] However, since the distance between the bumper skin of the rigid bumper beam and the front end of the towing hook is too large, it is difficult to ensure the installation rigidity and towing strength of the towing hook, which makes it difficult to meet the enhanced off-road towing load conditions.

[0009] The matters described in this background technology section are intended to enhance understanding of the background of the present disclosure, and may include matters beyond conventional technologies known to one of ordinary skill in the art to which this technology belongs.

[0129] like Fig. 9BAs shown, according to a typical towing hook, the front end of the towing hook 7a is installed to protrude forward from the front bumper skin of the bumper beam 2a at a predetermined distance L2 from the front bumper skin of the bumper beam 2a.

[0130] like Fig. 9A As shown, the towing hook assembly 100 according to one embodiment can reduce the distance L1 from the rigid unit 31 to the front end of the towing hook 70 .

[0131] As described above, compared with the typical towing hook of the comparative example, the towing hook assembly 100 according to one embodiment can reduce the distance from the rigid unit 31 to the front end of the towing hook 70, so that during towing, the torque applied to the towing hook 70 can be reduced, thereby ensuring the towing strength of the towing hook 70.

[0132] In addition, the towing hook assembly 100 according to one embodiment may ensure the mounting strength of the towing hook 70 by mounting the towing hook 70 on the bumper beam 20 through the mounting bracket 41 .

[0133] Therefore, the towing hook assembly 100 according to one embodiment can ensure the towing strength and the installation strength of the towing hook 70, so that the enhanced off-road towing load condition can be met.

[0134] Also, according to the towing hook assembly 100 according to one embodiment, when the towing hook 70 protrudes forward to a certain extent through the mounting bracket 41 , interference between the towing cable (not shown) and the front bumper 9 can be avoided.

[0135] When the towing hook assembly 100 according to one embodiment is towed, the first bolt 62 a , the first weld nut 62 b , the second bolt 64 a , and the second weld nut 64 b generate vertical resistance on the bumper beam 20 and the mounting bracket 41 .

[0136] Furthermore, in the towing hook assembly 100 according to one embodiment, the third bolt 66 a and the third weld nut 66 b generate a shear force on the bumper beam 20 and the mounting bracket 41 when towing.

[0137] Therefore, the towing hook assembly 100 according to one embodiment can ensure stable towing performance because the vertical resistance and the shear force act as a supporting load of the mounting bracket 41 during the towing process.

[0138] Meanwhile, the bracket side surface 49 of the mounting bracket 41 includes an upper reinforcement portion 57 and a lower reinforcement portion 59 , and at least one molding 56 formed on the third flange 55 .

[0139] Therefore, the towing hook assembly 100 according to one embodiment can improve the strength of the mounting bracket 41 in the vehicle body front-rear direction, the vehicle width direction and the vertical direction and the vehicle collision performance.

[0140] Furthermore, the bracket upper side 43 of the mounting bracket 41 is inclined from the upper portion to the lower portion, and has a structure connected to the upper portion of the bracket front side 45 .

[0141] As a result, the towing hook assembly 100 according to one embodiment can compactly realize the shape of the mounting bracket 41 and facilitate ensuring the strength of the front portion of the mounting bracket 41 .

[0142] Furthermore, the hook 73 of the towing hook 70 is connected to the leg portion 71 obliquely along the curve of the bumper beam 20 .

[0143] Therefore, the towing hook assembly 100 according to one embodiment can further improve the collision performance of the vehicle by increasing the performance of the towing hook 70 in the vehicle width direction in a small overlap collision of the vehicle.
