Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a towing hook mounting structure provided in a vehicle.

[0002]

[Prior Art]

 Conventionally, a towing hook (towing hook) is attached to the body of an automobile or the like, and as shown in FIG. 4, by using the towing hook 51, a cover-over type automobile 52 is transported by a trailer or a ship, Alternatively, the automobile 52 is towed by another automobile or the like.

As such a towing hook 51, for example, there is one as shown in FIGS. 5 and 6. This type of towing hook 51 is formed in a substantially U shape by bending one round bar in the middle, and the opposite end mounting portions 53 and 54 are provided on the bottom surface 55a of the cross member 55 or on one side. It is fixed to the vehicle body side of the automobile 52 by being joined to the side surface 55b by welding.

[0004]

[Problems to be solved by the device]

 However, in the above-described conventional mounting structure, the joint between the towing hook 51 and the cross member 55 is strong against the external force in the direction of arrow A, but insufficient in strength against the external force in the direction of arrow B. is doing. Therefore, when an external force acts on the towing hook 51 in the direction of the arrow B, the towing hook 51 is easily separated from the cross member 55. Moreover, the towing hook 51 is easily deformed when an impact load is applied, which may hinder the towing work.

The present invention has been made in view of such circumstances, and an object thereof is to provide a towing hook mounting structure capable of improving the mounting strength of the towing hook and having excellent workability. To do.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems of the prior art, in the present invention, one linear member is bent into a substantially U-shape to form a towing hook, and an L-shaped portion is formed at an intermediate portion of the towing hook facing each other. One surface of the letter-shaped reinforcing plate is installed, and the distance between the opposite ends of the towing hook is kept constant by the reinforcing plate, and the opposite ends of the towing hook are fixed to the left and right side surfaces of the cross member, respectively. At the same time, the other surface of the reinforcing plate is fixed to the bottom surface of the cross member.

[0007]

[Action]

 In the mounting structure of the towing hook according to the present invention, the ends of the U-shaped towing hooks, in which one surface of the L-shaped reinforcing plate is erected in the facing intermediate portion, are fixed to both side surfaces of the cross member, and Since the surface is fixed to the bottom surface of the cross member, it is possible to increase the attachment strength of the towing hook against external force in the peeling direction, and also to suppress elastic deformation (springback) after forming the towing hook. it can.

[0008]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

1 to 3 show an embodiment of the present invention, in which 1 is a cross member arranged at the lower part of the body of an automobile or the like, and 2 is a towing hook (tow) attached to the cross member 1. Hook). The cross member 1 is formed in a substantially U-shaped cross section with the opening facing upward, and the upper end is bent outward at a substantially right angle.

The towing hook 2 is formed by bending a single linear member, for example, a round bar into a substantially U-shape, and one side of an intermediate portion, which will be described later, facing each other is slightly curved inward. is doing. That is, the towing hook 2 includes a curved portion 3 that locks a towing strut (not shown), both end mounting portions 4 and 5 that are welded to the cross member 1 so as to face each other, and a left and right pair located between these portions. It is composed of the intermediate parts 6 and 7. The distance between the both end mounting portions 4 and 5 of the towing hook 2 is set so as to match the distance between both side surfaces 1a and 1b of the cross member 1.

Further, on one side of the towing hook 2 which faces the longitudinal direction of the cross member 1, an L-shaped reinforcing plate 10 in which a hook mounting surface 8 and a member mounting surface 9 are arranged orthogonally is attached. . The reinforcing plate 10 is fixed by placing the hook mounting surface 8 on one side of the intermediate portions 6 and 7 of the towing hook 2 with the member mounting surface 9 disposed above and welding the overlapping portions of the two. As a result, the hook mounting surface 8 is installed between the intermediate portions 6 and 7 of the towing hook 2 which face each other. Therefore, the reinforcing plate 10 has a function of suppressing the elastic deformation of the towing hook 2 which tends to return to its original shape after the bending and forming, and the reinforcing plate 10 causes the space between the opposite end mounting portions 4 and 5 of the towing hook 2 to face each other. The distance is kept constant.

In addition, on the hook mounting surface 8 of the reinforcing plate 10, two semicircular arc-shaped protrusions (beads) 11 are arranged at intervals in the vertical direction in the width direction. It is embossed to reinforce 10 itself. The member mounting surface 9 of the reinforcing plate 10 is formed to have a size substantially corresponding to the width of the bottom surface 1c of the cross member 1.

In order to attach the towing hook 2 thus configured to the cross member 1, first, the hook attaching surface 8 of the reinforcing plate 10 is fixed to the intermediate portions 6 and 7 of the towing hook 2. Then, in this state, both end mounting portions 4 and 5 of the towing hook 2 are overlapped with predetermined positions on both side surfaces 1a and 1b of the cross member 1, respectively, and the towing hook 2 is arranged so as to straddle the bottom surface 1c of the cross member 1. The member mounting surface 9 of the reinforcing plate 10 is superposed on the bottom surface 1c of the cross member 1. Then, the overlapping portions of the both end mounting portions 4 and 5 of the towing hook 2 and the both side surfaces 1a and 1b of the cross member 1 are fixed by spot welding, and the member mounting surface 9 of the reinforcing plate 10 and the cross member 1 are fixed. If the overlapping portion with the bottom surface 1c is fixed by spot welding, the towing hook 2 is attached to the cross member 1 (see FIGS. 1 to 3).

According to the mounting structure of this embodiment, since the towing hook 2 is fixed to both side surfaces 1a and 1b so as to straddle the bottom surface 1c of the cross member 1, both end mounting portions 4 of the towing hook 2 are fixed. The external forces in the peeling direction with respect to 5 act so as to cancel each other out, and the attachment portions 4, 5 of the towing hook 2 can be given sufficient strength. Further, since the reinforcing plate 10 is attached to the towing hook 2, the towing hook 2 is less likely to be deformed even when subjected to an impact load, and is less likely to be elastically deformed after being molded.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention. It

[0016]

[Effect of the device]

 As described above, in the towing hook mounting structure according to the present invention, one linear member is bent into a substantially U shape to form a towing hook, and the opposite ends of the towing hook are formed on the left and right sides of the cross member. In addition to being fixed to both sides, and reinforcing plates installed in the middle part of the towing hooks facing each other are fixed to the bottom surface of the cross member, it is possible to improve the mounting strength of the towing hooks and also to reduce the impact load. The deformation of the towing hook can be prevented.

Further, in the mounting structure of the present invention, since the elastic deformation after the towing hook is formed is suppressed by the reinforcing plate and the distance between the opposite ends is kept constant, the towing can be maintained during the welding operation. The ends of the hooks can be easily placed on both sides of the cross member so that they can be easily attached to each other.
