Abstract

PURPOSE:To fix a towing hook without marring the external appearance of an automobile and to prevent touching of a towing rope to a bumper, by fixing the towing hook in a state of hanging at the lower part of the rear sub-frame which constitutes a car body. CONSTITUTION:Mounting members 16 for fixing a rear differential case are set standing on the central part of a cross member in the car width direction, and moreover a towing hook 17 is fixed at the lower point of a rear sub-frame 13, that is, at the central part of the cross member 15. A U-shape hook member 17a of the towing hook 17 is protruded further than the lower end of a rear bumper at the front part of the rear bumper. As the towing hook 17 is positioned at the part covered by the rear bumper, it is possible to improve external appearance. Besides, as the towing hook 17 is protrudingly arranged below a car body in a state of hanging on the central part in the car width direction of, it is also used as a fastening hook for tire-down in the case of transporting a four-wheel automobile 10 and is utilised as a jack up point too.

Description

[Detailed description of the invention]

0001

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

0002

[Conventional example] Four-wheeled vehicles have towing hooks on their bodies for the purpose of towing other broken vehicles, etc., or for tying down the vehicle with ropes, etc. during transportation by truck or ship. It is arranged.

[0003] This type of tow hook is usually attached to the rear of the vehicle body in order to facilitate the towing of other disabled vehicles. 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, it is arranged to protrude rearward of the rear bumper 3 through the opening 4.

0004

[Problems to be Solved by the Invention] However, the above-described mounting structure for the towing hook 1 has a problem in that the appearance is poor because the opening 4 of the rear bumper 3 and the towing hook 1 are visible from the outside. .

[0005]Furthermore, the towing rope tends to hit the rear bumper 3 while towing another broken down vehicle, and there is a risk of damaging the rear bumper 3.

[0006] Furthermore, when the above-mentioned towing hook 1 is used as a tightening hook for tie-down when transporting an automobile, the rear bumper 3 is damaged, so it cannot be used as a tightening hook.

[0007]Furthermore, the above-mentioned towing hook 1 cannot be used as a jack-up point due to its location, and can only be used exclusively for towing. For this reason, conventionally, as shown in FIG. 7, a jack reinforcement member 7 is joined to the joint between the rear floor panel 5 and the side sill outer panel 6, and the jack reinforcement member 7 is connected to the joint between the rear floor panel 5 and the side sill outer panel 6. 8 is jacked up using jack 9.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to enable a towing hook to be attached without damaging the appearance of the automobile, and to prevent the towing rope from hitting the bumper during towing. To provide a towing hook mounting structure for an automobile that does not cause problems such as damage caused by the towing hook and allows the towing hook to be used as a tightening hook (tie-down hook) or as a jack-up point. be.

[0009]

[Means for Solving the Problems] In order to achieve the above-mentioned object, in the present invention, a tow hook is attached in a suspended state to a low point of a rear subframe constituting a vehicle body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 shows a four-wheeled vehicle 10.
FIG. 2 shows the structure of the rear body 11 of this four-wheeled vehicle 10. As shown in FIG. 2, the rear part 11 of the vehicle body is composed of a rear side member 12, a rear subframe 13, and a rear floor panel 14.

As shown in FIG. 2, the above-mentioned rear subframe 13 includes a cross member 15 made of a pipe material, which is attached between the pair of left and right rear side members 12 and arranged along the vehicle width direction (left and right direction). Equipped with Note that this cross member 15 is arranged below the rear side member 12.

[0013] A mount member 16 for attaching a rear differential case is erected at the upper part of the cross member 15 at the center in the vehicle width direction. moreover,
As shown in FIGS. 2 and 3, a towing hook 17 is attached to a lower portion of the rear subframe 13, that is, to the central portion of the cross member 15. As shown in FIGS.

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

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

[0016] In this way, the cross member 15
As clearly shown in FIG. 3, the U-shaped hook portion 17a of the towing hook 17, which is integrally attached to the tow hook 17, protrudes below the lower end 18a of the rear bumper 18 at the front portion of the rear bumper 18. Therefore, it is possible to tow another vehicle by tying a tow rope (not shown) to this U-shaped hook portion 17a.

According to the towing hook mounting structure configured as described above, there is no need to provide an opening in the rear bumper 18 and to place 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 tow hook 17
is disposed in a hanging state at the center in the vehicle width direction and protrudes below the vehicle body, so it can be used not only as a tightening hook for tie-down when transporting the four-wheeled vehicle 10, but also as a jack-up point.

Although one embodiment of the present invention has been described above,
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 towing hook 17 may be attached to any other lower part of the rear subframe 13.

[0019]

[Effects of the Invention] As described above, in the present invention, the towing hook is attached to a lower part of the rear subframe in a suspended state, so there is no need to provide an opening for installing the towing hook in the rear bumper. Therefore, it is possible to improve the appearance. Further, since the towing hook is arranged at a low position, the bumper can be prevented from being damaged by the towing rope tied to the hook. Moreover, the above-mentioned towing hook can be used not only for towing but also as a tightening hook for tie-down, and can also be used as a jack-up point.
