DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a towing hook disposed at the rear of a vehicle body of an automobile.

[0002]

2. Description of the Related Art A tow hook is attached to a body of a four-wheeled vehicle for the purpose of towing another malfunctioning vehicle or for tying down the vehicle with a rope or the like when transporting by truck or ship. It is arranged.

[0003] This type of towing hook is usually attached to the rear of the vehicle body to facilitate the towing of another failed vehicle or the like. Specifically, as shown in FIG. 5, the towing hook 1 is fixed to the rear end portion of the side member 2 of the vehicle body by welding, and the hook portion 1a of the towing hook 1 is formed on the rear bumper 3 as shown in FIG. In many cases, the rear bumper 3 is arranged so as to protrude rearward through the opening 4.

[0004]

However, in the mounting structure of the towing hook 1 as described above, the opening 4 of the rear bumper 3 and the towing hook 1 can be seen from the outside, so that there is a problem that the appearance is poor. .

In addition, the tow rope easily hits the rear bumper 3 during towing of another malfunctioning vehicle or the like, and the rear bumper 3 may be damaged.

Further, if the above-mentioned towing hook 1 is used as a tie-down tightening hook during transportation of an automobile, the rear bumper 3 will be damaged and cannot be used as a tightening hook.

Further, the above-mentioned towing hook 1 does not become a jack-up point due to its arrangement position, and can be used exclusively for towing. For this reason, conventionally, as shown in FIG. 7, the jack reinforcement member 7 is joined to the joint between the rear floor panel 5 and the side sill outer panel 6, and the joint between the jack reinforcement member 7 and the side sill outer panel 6 is formed. 8 is jacked up by a jack 9.

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and an object of the present invention is to attach a tow hook without impairing the appearance of an automobile, and tow a rope in contact with a bumper during towing. The present invention provides a tow hook mounting structure for an automobile, which does not cause a problem such as scratching, and can be used as a tightening hook (tie-down hook) or as a jack-up point. is there.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 shows a four-wheeled vehicle 10,
FIG. 2 shows the structure of the rear part 11 of the four-wheeled vehicle 10. As shown in FIG. 2, the rear portion 11 of the vehicle body includes a rear side member 12, a rear sub-frame 13, and a rear floor panel 14.

As shown in FIG. 2, the above-mentioned rear sub-frame 13 is provided between a pair of left and right rear side members 12 and is provided with a cross member 15 made of pipe material and disposed along the vehicle width direction (left-right direction). I have it. The cross member 15 is disposed below the rear side member 12.

A mount member 16 for mounting a rear differential case is provided upright above the center of the cross member 15 in the vehicle width direction. further,
As shown in FIGS. 2 and 3, a towing hook 17 is attached to a lower portion of the rear subframe 13, that is, the central portion of the cross member 15.

The above-mentioned towing hook 17 is formed by bending a single rod-shaped steel material into a substantially U-shape as shown in FIG. 4, and has a U-shaped hook portion 17a at the center. The hook 17a has curved portions 17b and 17c connected to both ends of the hook 17a.

Thus, the towing hook 17 has curved portions 17b and 17c at both ends thereof fitted to both front and rear portions of the center portion of the cross member 15 without gaps.
7 is welded to the cross member 15 in a suspended state. That is, the U-shaped hook portion 17a of the towing hook 17
Are projected below the cross member 15 as shown in FIGS. 2 and 3, and the curved portions 17b,
17c is fixed to the center of the cross member 15 by welding.

Then, the cross member 15 is
As shown in FIG. 3, the U-shaped hook portion 17a of the traction hook 17 integrally attached to the rear bumper 18 projects downward from the lower end 18a of the rear bumper 18 at a position in front of the rear bumper 18. Therefore, a tow rope (not shown) is tied to the U-shaped hook portion 17a so that another vehicle can be towed.

According to the towing hook mounting structure having such a configuration, it is not necessary to provide an opening in the rear bumper 18 and arrange the towing hook 17 through the opening.
Since 7 is located at a location covered by the rear bumper 18, the appearance can be improved. Moreover, the towing hook 17
Because it is projectingly disposed below the vehicle body under a state suspended in the central portion in the vehicle width direction, both when it serves as a clamping hook for the tie-down during transport of the four-wheeled vehicle 10, can also be used as a jack-up point.

As described above, one embodiment of the present invention has been described.
The present invention is not limited to the embodiments described above, and various modifications and changes can be made based on the technical idea of the present invention. For example, the shape of the towing hook 17 can be changed in various ways, and the mounting location of the towing hook 17 may be another location as long as it is a low location in the rear sub-frame 13.

[0019]

As described above, according to the present invention, the tow hook is attached to the lower part of the rear sub-frame in a suspended state, so that it is not necessary to provide an opening for disposing the tow hook in the rear bumper. Therefore, the appearance can be improved. Further, since the towing hook is disposed at a low position, the towing rope tied to this hook can prevent the bumper from being damaged. In addition, the above-mentioned towing hook can be used not only as a towing but also as a tie-down tightening hook, and can be used as a jack-up point. further,
Cross member towing the hook between the curved portions at both ends of the vehicle
Under the condition of being sandwiched in the front-rear direction,
Apply the curved parts at both ends to the cross member and
Because it is designed to be mounted, especially in the vehicle front-rear direction (vehicle
In the direction of supporting the load applied during towing)
The hook mounting strength can be sufficiently ensured.
