Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure around a mounting portion of a vehicle hook having holes for both towing and tightening.

[0002]

[Prior Art]

 As a conventional structure around a mounting portion of a vehicle hook, there is, for example, the one shown in Japanese Utility Model Laid-Open No. 59-129607 or FIG.

That is, in this figure, 1 is a front side member that is arranged on the side of the vehicle body and extends in the vehicle front-rear direction, 2 is a closing plate that is joined to the side surface of this front side member 1, and 3 is that is arranged in front of the vehicle. The first cross member 4, which is a strength member extending in the vehicle width direction, is a hook attached to the front end portion of the closing plate 2 by attaching bolts 5, 5, 5, and the lower portion of the hook 4 is for pulling and tightening. A hole 6 which is also a double hole is formed.

[0004]

[Problems to be solved by the device]

 However, as shown in FIG. 4, such a conventional vehicle hook mounting portion peripheral structure is provided in order to prevent the tow rope R attached to the hook 4 from interfering with the bumper 20 located on the front surface of the vehicle body as shown in FIG. The hole 6 has to be set as low as possible in the vehicle body, which causes a disadvantage in the strength of the hook 4.

That is, if the hole 6 is set downward, the offset from the stopping point with respect to the closing plate 2 is increased accordingly, and particularly when the hole 4 is input to the hook 4 in the left-right direction at the time of tightening. Both the closing plate 2 and the closing plate 2 receive a force in the out-of-plane direction, which is disadvantageous in terms of strength.

In order to solve such a problem, it is conceivable to separately provide a hole for pulling and a hole for tightening, but there is a problem that the hook is broken when the ropes are misplaced.

The present invention has been made in view of such a conventional problem, and is a vehicle having a dual-purpose hole for towing and tightening, in which the towing rope does not interfere with the bumper and is also advantageous in strength. An object is to provide a structure around a mounting portion of a hook for use.

[0008]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention comprises a cross member extending substantially in the vehicle body width direction and arranged substantially parallel to the vehicle body bumper, and a side member connected to the cross member and disposed on a side portion of the vehicle body extending in the vehicle front-rear direction. In a structure around a mounting portion of a vehicle hook equipped with a hook having a towing and tightening hole attached to a closing plate joined to the side member, a cross member between the hook and a vehicle body bumper is provided. A bracket was provided and a notch for hooking a pulling rope was formed at a position below the hole of the bracket.

Further, the bracket may be configured to be attached to both the hook and the cross member.

[0010]

[Action]

 At the time of towing, attach a tow rope to the hole and pull forward. In this case, the rope passes through the notch of the bracket, so that it can pass downward, and therefore it is possible to prevent direct interference between the rope and the bumper.Therefore, the hole position is provided above the hook as compared with the conventional case. be able to. Then, for lateral input, it is transmitted to the cross member as an in-plane force, and for longitudinal input, it is transmitted to the hook as an in-plane force. On the other hand, when tightening, the tightening hole can be provided above the hook as compared with the conventional case, so that the lateral input to the hook can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings by attaching the same reference numerals to the same parts as those of the related art.

FIG. 1 is a perspective view showing an embodiment of the present invention, in which 1 is a front side member, 2 is a closing plate, 3 is a first cross member, and 7 is a mounting bolt 8 at a front end portion of the closing plate 2. The hooks 8 and 8 are attached to each other, and a hole 9 for both pulling and tightening is formed in the lower portion of the hook. Reference numeral 10 denotes a bracket attached to the front surfaces of the hook 7 and the first cross member 3 with attachment bolts 11, 11, 11, and 11, respectively, and a groove 12 as a cutout portion for receiving the tow rope R at its lower end. Is provided below the hole 9, and both sides of the groove 12 serve as rope guide portions 13 for guiding the tow rope R to the groove 12.

In this embodiment, when pulling the rope R forward while pulling the rope R into the hole 9 during towing, the rope R engages with the groove 12 by the action of the rope guide portion 13. After passing 12, it will pass downward. At this time, the rope R can be prevented from being disengaged from the groove 12 by the rope guide portion 13 even if the rope R is slightly deviated from side to side. The force in the front-rear direction is transmitted to the hook 7 as an in-plane force, and the force in the left-right direction when pulled in the oblique direction is transmitted from the bracket 10 to the first cross member 3 as an in-plane force. Therefore, the input can be efficiently distributed, and almost no input in the horizontal direction is input to the hook 7.

Further, since the rope R is restricted by the groove, it is possible to prevent the bumper 20 and the rope R from interfering with each other as shown in the sectional view of FIG. Therefore, the position of the hole 9 can be provided above the hook 7, that is, at a position closer to the stop point than in the conventional case.

On the other hand, at the time of tightening, the position of the hole 9 can be set to the upper side as described above, so that the lateral input to the hook 7 can be reduced.

Further, as shown in FIG. 1, if the hook 7 and the bracket 10 are directly connected by the mounting bolts 11, the input in the lateral direction at the time of tightening can be effectively transmitted to the first cross member 3 as an in-plane force. it can.

[0017]

[Effect of the device]

 As described above, according to the present invention, the cross member between the hook and the vehicle body bumper is provided with the bracket, and the notch portion for hooking the tow rope is formed below the hole of the bracket. When pulling, the force in the front-back direction can be effectively input to the hook, and the force in the left-right direction can be effectively input to the cross member as an in-plane force. Also, direct interference between the tow rope and bumper can be prevented, holes can be provided above the hooks, and the lateral input can be reduced during tightening.
