Description

[Detailed Description of the Invention] This invention relates to an automobile front deck structure with an improved steering column mounting structure.

2. Description of the Related Art As a structure for attaching a steering column to a cowl top box of an automobile via a steering bracket, a structure as shown in FIG. 1 is conventionally known. In this case, a base end c of a steering bracket b is welded to the front surface of a cowl top box a, and a steering column f is attached to an attachment part e provided at a tip end d of the steering bracket b.

However, the above steering bracket b
has a structure in which only the proximal end c is fixed to the cowl top box a, so its rigidity is low, and the steering column f attached to the distal end d vibrates in the vertical direction, causing vibrations to the steering wheel g while driving. It has the disadvantage that it is transmitted.

Furthermore, in order to increase the vertical rigidity of the steering column f, there is a structure in which the steering bracket b is supported by a reinforcing member, but this becomes structurally complex and does not provide sufficient rigidity.

This invention was made with attention to the above circumstances, and its purpose is to fix the steering bracket to a cross member that runs in the vehicle width direction, support this cross member by the stay member, and fix the steering bracket to the cross member that runs in the vehicle width direction. The present invention aims to provide a front deck structure for an automobile that can increase the vertical rigidity of the vehicle and reduce steering wheel vibration.

This invention will be explained below based on an embodiment shown in the drawings. Figure 2 is a plan view of the front deck of an automobile, where 1 is the cowl top box, 2 is
2 is the front pillar. As shown in FIGS. 2 and 3, the cowl top box 1 is formed by welding the flange portions 4, 4 of two bent panels 3, 3, forming a cavity 5 inside. There is. A steering bracket 6 is attached to the front of the cowl top box 1.
This steering bracket 6 is divided into an upper case 7 and a lower case 8, and both cases 7 and 8 are integrally formed by welding flanges 7a and 8a. The base end of the upper case 7 is welded to the front surface of the cowl top box 1, and the base end of the lower case 8 is welded to the lower surface of the cowl top box 1. A steering column mounting portion 10 is provided on the lower surface of the tip portion 9 of the steering bracket 6 configured as described above, that is, on the lower case 8, and a steering column 12 is mounted in an inclined state to this mounting portion 10 by a bracket 11. It is being Further, on the upper surface of the tip portion 9 of the steering bracket 6, that is, located directly above the steering column mounting portion 10, a fourth
As shown in the figure, a support portion 13 having an arcuate cross section is provided. A midway portion of a cross member 14 passing in the vehicle width direction is fitted into this support portion 13. This cross member 14 is formed of a pipe provided parallel to the front portion of the cowl top box 1, and the middle portion of this cross member 14 is welded and fixed to the upper case 7 by a bracket 15. Further, arc-shaped holders 16, 16 are protruded from the front pillars 2, 2 facing both ends of the cross member 14, and these holders 1
6 and 16 support both ends of the cross member 14. Further, the upper surface openings of the pedestals 16, 16 are covered by arc-shaped lids 17, 17, and the pedestals 16, 1
6, both ends of the cross member 14 are fixed. Further, a cross member 14 located near the steering bracket 6
A stay bracket 18 is attached to the
A plurality of weld nuts 19 are attached to this stay bracket 18. The upper end of the stay member 20 is attached to the stay bracket 18. The stay member 20 is formed from a pipe 21, an upper mounting plate 22 provided at the upper end of the pipe 21, and a lower mounting plate 23 provided at the lower end of the pipe 21. The upper mounting plate 22 of the stay member 20 is fastened to the weld nuts 19 of the stay bracket 18 by a plurality of bolts 24. Further, the lower mounting plate 23 of the stay member 20 is attached to the front pillar 2 by a plurality of bolts 25...
It is tightened and fixed at the bottom of the. Therefore, the stay member 20 is attached to the lower part of the cross member 14 in an inclined state to suppress vibration of the cross member 14 in the vertical direction. Furthermore, an instrument mounting plate 26 is provided on the pipe 21 of the stay member 20, and electrical components 27 such as a microcomputer, a fuse box, and a relay are mounted on this instrument mounting plate 26.

Since the steering bracket 6 fixed to the cowl top box 1 is reinforced by the cross member 14, and this cross member 14 is reinforced by the stay member 20, the vertical rigidity is particularly enhanced. Therefore, vertical vibration of the steering column 12 attached to the tip 9 of the steering bracket 6 can be suppressed. In addition, when assembling the cross member 14, the bracket 15 and the lids 17, 17 are assembled to the cross member 14 in advance, and the support part 13 of the steering bracket 6 and the cradle 1 are assembled from above.
6 and 16 improves assembly workability.

In addition, the stay member 2 to which the electrical component 27 is attached in advance is
0 between the cross member 14 and the front pillar 2, the outfitting of the electrical equipment 27 can be simplified.

As explained above, in this invention, the steering bracket is reinforced by a cross member that runs in the vehicle width direction, and the cross member located near the steering bracket and the lower part of the front pillar are reinforced by stay members. from,
The vertical rigidity of the steering bracket can be increased, and the vibration of the steering wheel during driving can be reduced. Further, electrical components can be attached to the stay member, and the installation of the electrical components can be facilitated by attaching the stay member.
