DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steering member mounting structure.

[0002]

2. Description of the Related Art As a conventional mounting structure for a steering member, for example, one shown in FIGS. 4 to 6 is known (for a similar technique, see Japanese Patent Application Laid-Open No. 5-85415).

[0005] Reference numeral 1 denotes a front pillar, which has a closed cross-sectional structure including an inner panel 2 and an outer panel 3. The rear end of the front fender 4 (see FIG. 6) is joined to the outer panel 3. The inner panel 2 is vertically divided into an inner panel upper 5 and an inner panel lower 6, and the upper part 6a of the inner panel lower 6 is overlapped with the lower part 5a of the inner panel upper 5 from the vehicle cabin R side. Both are integrated.

A reinforcing brace 7 is provided on the inner surface of the outer panel 3 together with an outer door hinge 8 and bolt / nut means 9.
Are tightened together. The brace 7 is formed with an extension 10 toward the inner panel 2, and the tip of the extension 10 is sandwiched between the inner panel 2 and the outer panel 3.

[0005] Reference numeral 11 denotes a steering member, and a mounting bracket 12 is fixed to the end 11a. The mounting bracket 12 is formed with three mounting holes 13, and the mounting holes 13 are mounted on the inner panel lower 6 by bolt and nut means 14 (see FIG. 6). The inner panel lower 6 where the mounting bracket 12 is mounted is provided with a reinforcement 15 for reinforcement, and the inner panel lower 6 and the mounting bracket 12 are mounted together with the reinforcement 15.
Are fastened together by the bolt 14.

[0006]

However, in such a conventional technique, since the mounting bracket 12 of the steering member 11 is mounted on the flat surface of the inner panel lower 6, the width of the vehicle added from the steering member 11 is increased. The rigidity with respect to the direction input F is low, and the inner panel lower 6 is easily deformed. Therefore, the addition of the reinforcement 15 is indispensable as a countermeasure for this, and the number of parts and the cost are increased.

Further, since the lower part 5a of the inner panel upper 5 is simply joined to the upper part 6a of the inner panel lower 6 by being superimposed thereon, it is difficult to perform a positioning operation between the inner panel upper 5 and the inner panel lower 6. Also, it is difficult to obtain a bonding strength between the two. Therefore, it is necessary to increase the thickness of the inner panel upper 5 and the inner panel lower 6 in order to increase the coupling strength, which causes an increase in the weight of the vehicle body.

The present invention has been made by paying attention to such prior art, and has high rigidity with respect to the input in the vehicle width direction applied from a steering member, and has a positioning accuracy and a joint strength between the inner panel upper and the inner panel lower. The present invention provides a steering member mounting structure that is advantageous in terms of (1).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. In addition, the same reference numerals are given to portions common to the related art, and overlapping description will be omitted.

In this embodiment, the inner panel upper 1
6 is extended downward, and the inner panel lower 1 is extended.
The portion overlapping with the upper portion 17a of 7 is enlarged. The upper portion 17a and the lower portion 16a have an end corresponding portion 19 corresponding to the end 18a of the steering member 18,
20 are set, and embossed portions 21 and 22 are formed toward the vehicle cabin R side so as to surround the front sides of the end corresponding portions 19 and 20. This embossed portion 21, 2
2 has flat embossed surfaces 21a, 22a and two vertical surfaces 21b, 21c, 22b, 22c, respectively, and the embossed surfaces 21a, 22a have three mounting holes 23, 24, respectively.
(See FIG. 3). Further, the end corresponding portions 19, 2 surrounded by embossed portions 21, 22.
0 also have separate mounting holes 25 and 26, respectively.

The upper part 17 of the inner panel lower 17
a and the lower part 16a of the inner panel upper 16 are superimposed in a state where the upper part 17a is positioned on the vehicle cabin R side,
Both form the inner panel 28 of the front pillar 27. When the inner panel lower 17 and the inner panel upper 16 are overlapped with each other, the embossed portions 21 and 22 having shapes substantially corresponding to both are formed, respectively, so that it is easy to perform a positioning operation of both. In addition, since the shapes of the upper portion 17a and the lower portion 16a are three-dimensional, respectively, the bonding strength after polymerization is high.

On the other hand, the end 18 of the steering member 18
a mounting bracket 29 fixed to the end 18.
The mounting bracket 29 has a shape that closes the mounting holes 23 on the embossed portions 21 and 22.

The terminals of the vertical surfaces 21b are also matched with each other, and both vertical surfaces 22b and 34a are in a continuous state. Further, the tip of the bolt 35 to which the extension portion 34 is fastened is in contact with the mounting bracket 29.

Therefore, when a light collision is applied to the opposite side surface of the vehicle body, even if an input F in the vehicle width direction is applied to the front pillar 27 from the steering member 18, the input F is applied to the embossed portion 21. 22 vertical surface portions 21b, 21
c, 22b, and 22c, the rigidity with respect to the input F is high, and the deformation of the inner panel 28 can be prevented. In particular, the rear vertical surface portions 21b and 22b of the embossed portions 21 and 22 are
The vertical surfaces 21b and 22b function effectively in increasing rigidity because they are close to each other so as to surround the front side of the end 18a.

Further, since the vertical surface portion 22b and the vertical surface portion 34a of the brace 33 are continuous, the embossed portions 21, 2
2 can be effectively transmitted to the brace 33 side, and the rigidity with respect to the input F can be further increased. In addition, since the ends of the bolts 35 that fasten the ends of the end corresponding portions 19 and 20 and the extension portions 34 are in contact with the mounting bracket 29 of the steering member 18, the input F is Can also be transmitted to the end corresponding portions 19, 20 and the extension portion 34 via
The rigidity with respect to the input F is further improved.
