DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a vehicle body structure at a front portion of a vehicle according to the present invention will be described in detail with reference to the drawings. FIG.
1 is a perspective view showing the entire vehicle 1. A front bumper 2 is provided at the front of the vehicle. FIG. 2 is an enlarged perspective view of the inside of the front part of the vehicle. Frames 3 are arranged on both sides of the vehicle 1 along the front-rear direction. A cylindrical member 4 is provided at the front end of the frame 3 along the vehicle width direction.
Is provided. The power steering pipe 6 is fixed to the front of the member 4 in the vehicle using a pipe clamp 5.

The power steering pipe 6 is disposed in front of the member 4 in the vehicle for the following two reasons. First, since a steering gear box, a condenser of an air conditioner, and the like (not shown) are disposed behind the member 4 on the vehicle side, there is no space for the power steering pipe 6 to pass through. Further, when cooling the increased power steering oil temperature, the wind is more likely to be received in front of the member 4 in the vehicle, so that the power steering pipe 6 is suitable for cooling.

Next, a bumper inner 7 is bolted to the side surface of the front end of the frame. A reinforcing member 8 having a U-shaped cross section is fixed to a substantially central portion in the vehicle width direction on the back side of the inner side of the bumper so as to protrude rearward of the vehicle. The reinforcing member 8 and the pipe clamp 5 are disposed at the same position in the vehicle width direction. Additionally, a bumper (not shown)
Is attached to the front of the bumper inner 7 in the vehicle. The reinforcing member 8 will be described with reference to FIGS.

FIG. 3 is a perspective view of the reinforcing member 8, and FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. The reinforcing member 8
Is provided with a flange 9 at the rear. A substantially central portion of the flange 9 forms an escape portion 10 that is depressed toward the front of the vehicle. The flange 9 has a contact area with the power steering pipe 6 in order to reduce an impact load when the bumper inner 7 is deformed due to a frontal collision of the vehicle 1 and the rear surface of the reinforcing member 8 hits the power steering pipe 6. It is provided for the purpose of increasing the number.

FIG. 5 is a perspective view of the pipe clamp 5, and FIG. 6 is a longitudinal sectional view taken along line VI-VI of FIG.
The pipe clamp 5 has a substantially U-shape and has two insertion holes 11 for the power steering pipe 6. This insertion hole 1
The method of passing the power steering pipe 6 through the pipes 1 and 11 is as follows. Provided outward from the insertion holes 11, 11;
The power steering pipe 6 is inserted through the insertion holes 11, 11 through a tapered notch portion having a large outer side and a small insertion hole 11, 11 side.
Supported within.

In order to prevent the pipe clamp 5 from being deformed when a load is applied, a rigid stopper 12 is embedded between the insertion holes 11 and 11 and at a position forward of the power steering pipe 6 in the vehicle. I have. Further, legs 13, 13 are provided at both ends of the pipe clamp 5, and the pipe clamp 5 is fixed to the member 4 by being sandwiched between the legs 13, 13. The material of the pipe clamp 5 is preferably a synthetic resin such as a PP (polypropylene) resin. The reason for this is that the molding is easy, the durability against vibration and some external force and the water resistance are excellent, and the notch adjacent to the insertion holes 11 and 11 is bent at the time of assembly, so that the workability is good and the cost is low. Because.

The pipe clamp 5 and the reinforcing member 8 are arranged at the same position in the vehicle width direction, and the relief portion 10 of the reinforcing member 8 and the height of the pipe clamp 5 are also the same. When a load is applied to the front bumper 2 due to a frontal collision of the vehicle 1, the reinforcing member 8 and the pipe clamp 5
By both effects, the deformation of the power steering pipe 6 can be prevented.

Another embodiment of the present invention The part where the stopper 12 is embedded in the pipe clamp 5 is not limited to the space between the insertion holes 11 of the power steering pipe 6 as described above. For example, it may be embedded in a ring shape around the insertion hole 11.

[0015]

As described above, according to the vehicle body structure at the front part of the vehicle according to the present invention, (1) Even if a load is applied to the front bumper due to a frontal collision of the vehicle, if the load is light, the reinforcing member is used. The power steering pipe is not deformed by the pipe clamp.
Therefore, the function of the power steering is maintained normally even immediately after the accident. (2) When the vehicle is repaired due to the above-mentioned accident, only the front bumper and the inner bumper need to be replaced.
