Embodiment 1

[0032] Such as Figure 1-3 As shown, the present embodiment is a tow hook structure 100 . The tow hook structure 100 changes the structural form of the traditional tow hook, and solves the problem of insufficient strength of the tow hook due to the high drag force. The tow hook structure 100 includes an outer plate 1 , an inner plate 2 , a bottom plate 3 and a hook body 4 .

[0033] The outer panel 1 includes an end face portion 11 and a side wall portion 12 , the end face portion 11 is connected to the side wall portion 12 . In this embodiment, the end face portion 11 and the side wall portion 12 are integrally formed, that is, the outer plate 1 is formed by bending one plate. The upper surface of the end face portion 11 is lower than the upper surface of the side wall portion 12 .

[0034] The shape of the inner panel 2 is substantially the same as that of the side wall portion 12 of the outer panel 1 , and one end of the inner panel 2 is connected to the end surface port...

Embodiment 2

[0044] Such as Figure 4 with Figure 5 As shown, this embodiment provides a tow hitch assembly, including the above tow hitch structure 100 and the longitudinal beam 200 . Along the horizontal direction, the width of the longitudinal beam 200 gradually increases from the end surface to the center. The tow hook structure 100 is disposed at the bottom of the longitudinal beam 200 .

[0045] The side wall portion 12 of the outer panel is connected to the outer side wall 210 of the stringer, and the end face portion 11 of the outer plate is connected to the bottom surface 220 of the stringer. One end of the inner panel 3 close to the hook body is connected to the inner side wall 230 of the stringer, and one end away from the hook body is connected to the bottom surface 220 of the stringer. The bottom plate 3 is connected to the bottom surface 220 of the longitudinal beam. The longitudinal beam 200 closes the top opening of the tow hitch structure 100, and the closed box-like ...

Abstract

The disclosure relates to a tow hook structure, a tow hook assembly and a vehicle. The trailer hook structure includes: an outer plate, including an end face part and a side wall part, and the end face part is connected to the side wall part; an inner plate, connecting the end face part; a bottom plate, respectively connecting the outer plate and the inner plate, and the outer plate, the inner plate and the bottom plate form a top opening The box-shaped structure; the hook body includes an arc part and a straight part, the straight part is arranged on the bottom surface of the bottom plate, and the arc part is connected with the straight part and extends out of the end part. The tow hook of the present disclosure has high structural strength, is convenient to tow, and is favorable for energy absorption during collisions.

Description

technical field [0001] The present disclosure generally relates to the technical field of automobiles, and in particular relates to a tow hook structure, a tow hook assembly and a vehicle. Background technique [0002] The main function of the tow hook is to get the vehicle out of bad road conditions and tow other non-powered or powered damaged vehicles. The tow coupler of the non-load-bearing vehicle body generally adopts the following two structural forms: one is a fixed structure tow coupler, which is directly welded to the vehicle body or frame, and the other is a removable tow coupler, which is directly threaded on the frame. [0003] With the first type of structure, the tow hook structure is greatly affected by the layout position requirements and the shape of the front bumper, and has higher requirements on the structure of the bracket. Generally, it needs to be welded with thicker steel plates, and the overlapping area with the longitudinal beam is relatively large....
