Description

[Detailed description of the invention] Industrial application field The present invention is an improvement of a reinforcing member that is arranged in the vehicle width direction at the center of the instrument panel and that is connected to the vehicle body pillars at both ends to hold the steering shaft in place. It is related to.

Conventional technology This kind of reinforcing material in the past is one in which the upper reinforcing material, the lower reinforcing material, and the steering support are welded together, as shown in Figure 2 of Japanese Utility Model Application Publication No. 59-72172. As shown in FIG. 1 of the same publication, a structure is adopted in which a lower reinforcing member and a steering support part are integrally formed by press working, and this is welded to an upper reinforcing member.

Problems to be Solved by the Invention Although the structure in which the above-mentioned upper reinforcing material, lower reinforcing material, and steering support are welded together has a high rigidity for holding the steering wheel, it has the drawback of increasing weight and cost. On the other hand, the above-mentioned lower reinforcing material and steering support that are press-molded as one unit may lack stiffness to hold the steering wheel unless the wall thickness is increased, which also has disadvantages such as increased weight and cost. It leads to.

Therefore, the present invention was devised for the purpose of providing a reinforcing material for holding the steering wheel of an instrument panel, which minimizes the increase in weight and cost, and has sufficient steering holding rigidity without compromising productivity. It is something that

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a reinforcing material for the instrument panel that is arranged in the vehicle width direction and has both ends connected to the vehicle body pillars. A lower reinforcing member integrally press-molded with a steering support part is provided between both ends at a portion corresponding to the steering device, and a lower reinforcing member has a width corresponding to the steering support part, is in contact with the part, and has an upwardly bulging part. The formed intermediate reinforcing member is arranged in the vehicle width direction and has both ends connected to the vehicle body pillar, and has an upwardly bulging portion formed at a portion corresponding to the steering device between the both ends, and The intermediate reinforcement is formed of a three-part welded integral body with an upper reinforcement that abuts the entire lower reinforcement, and the intermediate reinforcement is connected to the bulge of the upper reinforcement at each outer side of the bulge. It has a structure in which it is welded to each inner surface of the

Effect: According to the present invention, the intermediate reinforcing member, which is formed integrally with the lower reinforcing member and has a width corresponding to the steering support part, is brought into contact with the steering support part, and the intermediate reinforcing member bulges out. Each outer surface of the upper reinforcing material is welded to each inner surface of the bulging portion of the upper reinforcing material, and the three parts are joined together by welding, etc., resulting in a three-dimensional reinforced structure, with As a result, the rigidity is significantly increased, and the thickness of each reinforcing material can be reduced accordingly, making it possible to reduce the weight.

Embodiment The drawing shows an example of implementation, and the reinforcing member 1 of the instrument panel is arranged in the vehicle width direction and has a shape in which both ends are connected to the vehicle body pillars, and a portion corresponding to the steering device between the two ends is provided. A lower reinforcing member 3 that is integrally press-molded with the steering support part 2, an intermediate reinforcing member 4 that has a width and size corresponding to the steering support part 2 and comes into contact with the part 2, and The upper reinforcing member 5 and the upper reinforcing member 5 are shaped to be in contact with the entire body, and the three members are integrally joined by welding to form an integral body.

The intermediate reinforcing member 4 has upwardly bulging parts 6 and 7.
The upper reinforcing member 5 also has an upwardly protruding portion 8 formed at a portion corresponding to the steering device.

The intermediate reinforcing material 4 is attached to the outer surfaces 9, 1 of the bulges 6, 7.
0, 11, 12, 13 and 14, the corresponding inner surfaces 15, 1 of the bulge 8 of the upper reinforcement 5
6, 17, and 18 are welded.

Of course, the lower reinforcing member 3, the intermediate reinforcing member 4, and the upper reinforcing member 5 are in contact with the flange-shaped portions 19, 20, 2.
1, 22, 23, etc. are welded at the overlapping parts.

As a result, as shown in FIGS. 2 and 3, the steering support portion 2 is
A three-dimensional reinforced structure is formed by the intermediate reinforcing material 4 and the upper reinforcing material 5, and its rigidity is significantly increased.

For this reason, the thickness of the lower reinforcing member 3, intermediate reinforcing member 4, and upper reinforcing member 5 can be reduced in proportion to the increased rigidity due to the three-dimensional reinforcing structure, thereby reducing weight. be.

As shown in FIG. 4, the reinforcing material 1 having the above structure is arranged at the lower center of the instrument panel 24 so that the longitudinal direction of the reinforcing material coincides with the vehicle width direction W-W. It is connected to the pillar and is also fixed to the vehicle body at the central part by a bracket 25, supports the weight of the meter box 27 etc. via the mounting seat 26, and is supported by the steering support part 2 via the brackets 28, 29. It supports the steering outer tube 30.

In FIG. 4, numeral 31 is a dash panel, numeral 32 is a cowl, numeral 33 is a safety pad of the instrument panel 24, and numeral 34 is a steering column cover.

Effects The present invention has the configuration and operation described above, and has a width and size corresponding to the steering support part that is integrally formed with the lower reinforcing member by press molding, and a part 2 is provided with The intermediate reinforcing material and the upper reinforcing material that are in contact with each other are welded on each side of their bulging parts to form a three-dimensional reinforcing structure, which has sufficient steering holding rigidity. Because of its three-dimensional reinforcement structure, it is possible to reduce the thickness of each of the upper, middle and lower reinforcements while maintaining sufficient holding rigidity, minimizing weight and cost increases and improving productivity. It has the effect of preventing sleep.
