DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for a steering column, and more particularly, to a vehicle generally referred to as a one-box car, in which an engine is not mounted on a front portion of the vehicle and a front panel and a front panel are provided on the front of the vehicle. The present invention relates to a structure applied to a cab-over type vehicle provided with a windshield standing up.

[0002]

2. Description of the Related Art Conventionally, in a bonnet type vehicle having an engine at the front of the vehicle, a cowl box for taking in outside air is usually provided below a windshield. Since the cowl box is formed in a box cross-sectional shape, the cowl box has high rigidity and is generally supported by using the cowl box when supporting the steering column.

On the other hand, as shown in FIG. 8, a cab-over type vehicle is provided in which a front panel 01 is provided upright on the front of the vehicle and a windshield 02 is provided upright on the front panel. In other words, outside air is taken in from a position lower than the windshield 02, and no cowl box is provided. The front panel 01 is composed of a front panel outer 011 and a front panel inner 012. When a steering column is supported in such a vehicle, a support member 02 having a box-shaped cross section spans the vehicle width direction, and the steering column is supported by the support member 02. Further, when the supporting strength is to be increased, the supporting member 02 should be provided at a position where the supporting strength is to be increased.
Is connected to the front panel 01 or the floor panel 05 via the connecting members 03 and 04.

[0004]

In recent years, various demands have been made by consumers on vehicles such as driving stability and riding comfort, and higher driving stability is also required for cab-over type vehicles. Therefore, the support strength and the support rigidity of the steering column are also required to be higher. However, when the supporting strength and the supporting rigidity are increased in the above-described conventional technology, the cross-sectional area of the supporting member 02 is increased, and further, the plate thickness of the connecting members 03 and 04 is increased, or a reinforcing material is added. However, in this case, there is a problem that weight and cost are increased. In addition, the rear side of the front panel 01 is provided with an air-conditioning unit and the duct is routed. Therefore, when the cross-sectional area of the support member 02 is increased, the arrangement and the routing are affected. It was difficult to increase the cross-sectional area of the support member 02. In addition, in order to realize the installation of the air conditioning unit and the like, in one support member 02,
The part that supports the steering column has a large cross-sectional area,
It was difficult to form the air-conditioning unit in a shape in which the cross-sectional area was changed depending on the region, such as reducing the cross-sectional area, and it was difficult to achieve it at low cost by using inexpensive processing such as pressing. . In addition, the support member 02
If the cross-sectional area changes in the middle in this way, if there is an input such as vibration during traveling or impact at the time of collision, there is a risk that stress will concentrate on this cross-sectional area change part and breakage will occur. There was a possibility that it could not sufficiently contribute to the strength of the vehicle body.

The present invention has been made in view of the above-mentioned conventional problems, and does not cause an increase in weight and cost, and also has an effect on the arrangement of other components such as an air conditioning unit, thereby increasing the degree of freedom in design.

[0010]

According to the present invention, a steering column is supported by a steering mount member having a closed cross section whose both ends are supported by a vehicle body. Since it is structured to be supported by the high rigidity portion that is connected to the second box cross-sectional shape portion, high supporting strength and high supporting rigidity can be obtained. In addition, this makes it possible to suppress the amount of rearward movement of the steering column and the steering at the time of a frontal collision of the vehicle.

Further, in the structure of the present invention, the steering mount member, the first box section and the second box section are supported by three closed sections. By increasing the cross-sectional area of the second box cross-section, even if each of the steering mount member and the first box cross-section having the entire width of the vehicle is formed to have a relatively small cross-section, necessary and sufficient rigidity is obtained. Can be secured.
That is, in the portion for supporting the steering column, one end of the reinforcing member is connected to the first box cross-sectional shape portion, and the other end is connected to the hanging portion. It is easy to set the shape and size to have the strength and rigidity necessary to support the steering column, and it is possible to change the shape formed by the reinforce outer panel and the reinforce inner panel. The first box section does not need to have a section modulus (cross section size) necessary to support the steering column, and the front body strength required for the first box section is eliminated.・ Sufficient rigidity is required, a relatively narrow constant cross-section can be set over the entire vehicle width direction, and there is no need to consider stress concentration due to large changes in the cross-section. Ri, moreover, the second box-cross section portion, since only provided in the vicinity of the steering column support site, can ensure a space for mounting the air-conditioning equipment.

According to the second aspect of the present invention, the reinforcing member is connected to the first handle according to the difference between the right handle specification and the left handle specification.
When connecting to the right handle joint or the left handle joint provided at the box cross-section and the hanging part, respectively, the right handle joint and the left handle joint are respectively oriented in the vehicle width direction. Since the reinforcing member is formed of a straight plane, and the connecting portion provided on the reinforcing member is also formed of a straight plane in the vehicle width direction, the reinforcing member is connected to the connecting portion for the right handle and the connecting portion for the left handle. It can be selectively connected to any, and the box cross section member and the reinforcing member,
The right-hand drive specification and left-hand drive specification can be shared. Therefore, the amount of capital investment can be greatly reduced as compared with the case where the common use is not performed, and the manufacturing cost can be reduced.

According to the third aspect of the present invention, one of the left and right sides of the box section member on which the reinforcing member is not attached is extended from a portion forming the first box section shape section. Vehicle-mounted equipment such as an air conditioning unit can be installed below the extension. Therefore, even if the extension portion and the hanging portion extend in the vehicle width direction, the extension portion can be effectively used on the side where the reinforcing member is not connected, and the right handle type and the left handle type can be shared. Can be executed even more rationally, and the cost can be reduced.

According to the fourth aspect of the present invention, since the reinforcing member and the floor panel are connected by the pedal support bracket, the support strength and the support rigidity of the steering column are further improved, and the vehicle body rigidity at the front of the vehicle is also improved. I do.

Next, description will be made with reference to a perspective view shown in FIG.
As shown in this figure, an air conditioning unit 70 is attached to the front end of the vehicle and extends from the left end of the vehicle to the center. The air conditioning unit 70 includes a fan unit 72 that houses an electric fan 71 in order from the left, an evaporator unit 73 that houses an evaporator (not shown), and an air mixing unit 74 that houses a heater core and an air mixing door (not shown). The air mixing section 74 is disposed substantially at the center of the vehicle and in front of a center console (not shown). In addition, a duct connected to a duct (not shown) extending toward each outlet such as a defroster outlet, a central vent outlet, and a side vent outlet (not shown) is provided at an upper end portion of the air mixing unit 74. A connection portion 75 is provided. The duct connecting portion 75 is provided at an overlapping position when the above-described reinforcing member 5 is virtually extended in the vehicle width direction.

In the air conditioning unit 70, as shown in FIG. 6, the fan portion 72 has brackets 72a and 72b formed around a convex portion 12d which forms an outside air intake 12e and projects upward from the floor panel 12.

Through the brackets 74c and 74d shown in FIG.
And the floor panel 12. In addition,
FIG. 7 is a longitudinal sectional view at the center of the vehicle.

In the steering column support structure of the present embodiment described above, the steering column 41 is supported at both ends by the steering mount member 4 having a cylindrical closed cross section fixed to the front pillar 13. A portion of the steering mount member 4 that supports the steering column 41 is formed by a first box-shaped section 21 having left and right parts fixed to the front pillar 13.
And a high rigidity closed cross-section structure having a first box cross-sectional shape portion 21 and a second box cross-sectional shape portion 22 fixed to the hanging portion 3c. Support strength and support rigidity can be obtained. Therefore, the steering stability is improved, and the amount of rearward movement of the steering column 41 and the steering wheel 40 at the time of a vehicle frontal collision can be suppressed. In addition, since the steering mount member 4 and the reinforcing member 5 are connected by the pair of left and right connection brackets 44, higher support strength and rigidity improvement can be obtained as compared with the case where the connection is performed by one connection bracket 44. Can be

Further, in the embodiment, the steering column 41 is formed by combining the steering mount member 4, the first box section 21 and the second box section 22.
In order to support with two closed cross sections, the cross-sectional area of the second box cross-sectional shape part 22 is increased as necessary, so that each of the steering mount member 4 and the first box cross-sectional shape part 21 existing over the entire width of the vehicle is provided. Is formed to have a relatively small cross-sectional area, necessary and sufficient support strength and support rigidity can be secured. That is, in the portion supporting the steering column 41, one end of the reinforcing member 5 is connected to the first box-shaped section 21.
And the other end is connected to the hanging part 3c, so that the cross-sectional size of the reinforcing member 5 can be changed between the hanging part 3c and the strength required for supporting the steering column 41. It is easy to set the shape and size to have rigidity. Therefore, the cross-sectional area of the steering mount member 4 and the first box cross-sectional shape portion 21 existing in the entire width in the vehicle width direction is reduced by a small cross-section that does not interfere with other components such as the air conditioning unit 70 arranged on the side of the steering column 41. It can be formed in a shape that can secure the necessary and sufficient support strength and support rigidity and can change the cross-sectional area in the middle of the member while obtaining high design flexibility by forming it in an area. Since it is unnecessary, stress can be prevented from being concentrated at the time of input of traveling vibration, impact at the time of collision, and the like, and vehicle body strength can be improved. In addition, the second box cross-sectional shape part 22 is provided with a reinforcing member 5 having an L-shaped cross section.
And is provided only on a part of the entire width of the vehicle. Since the left and right ends are open, the second box-shaped section 22 is connected to a device mounted on the front of the vehicle. Temporary holding can also be performed through cables and the like, and the workability of assembling equipment can be improved.

Further, in the state of the primary processing, the box section member 20 has right handle coupling portions 52R, 53R and left handle coupling portions 52R, which are formed in a flat plane in the vehicle width direction.
L and 53L are symmetrical with each other, and the reinforcing member 5 is also a connecting portion 5 formed by a straight plane in the vehicle width direction.
a, 5b, the reinforcing member 5 is connected to the right handle connecting portions 52R, 53R and the left handle connecting portions 52L, 5L.
It can be linked to any of the 3Ls. Therefore, the reinforcing member 5 is selectively coupled to the right handle coupling portions 52R, 53R and the left handle coupling portions 52L, 53L of the box section member 20 according to the difference between the right handle specification and the left handle specification. And the box section member 20 and the reinforcing member 5 can be shared by the right-hand drive specification and the left-hand drive specification, so that the capital investment amount can be greatly reduced as compared with the case where no common use is made. The effect that the manufacturing cost can be reduced is obtained.
In addition, in the present embodiment, in the extension 3d of the reinforcement outer panel 3 of the box section member 20, the side where the reinforcing member 5 is not connected is configured to be used for mounting the air conditioning unit 70. When the member 20 is shared by the left and right handle specifications, even if the extension 3d is provided over the entire width in the vehicle width direction, it can be effectively used without wasting it, and the right handle specification and the left handle specification are shared. Can be executed even more rationally, and the cost can be reduced.

Further, in the present embodiment, the reinforcing member 5 and the floor panel 12 are two pedal support brackets 6.
Since the steering column 41 is connected via the b and 6c, the support strength and the support rigidity of the steering column 41 are further improved, and the rigidity of the vehicle body at the front of the vehicle is also improved. In addition, the steering mount member 4 is attached to the support members 81 and 82 at the center.
Therefore, the support strength and the support rigidity of the steering column 41 by the steering mount member 4 are further increased. Moreover, since the support members 81 and 82 are used for mounting the air conditioning unit 70, the support of the air conditioning unit 70 is rationalized, and the cost can be reduced.

Although the embodiment has been described with reference to the drawings, the present invention is not limited to this. For example, in the embodiment, the example is shown in which the steering mount member 4 is connected to the reinforcing member 5 by the connection bracket 44. However, the steering column 41 may be connected to the reinforcing member 5, or Both the mount member 4 and the steering column 41 may be connected. In the embodiment, a columnar member is used as the steering mount member 4. Although this is advantageous in terms of cost, the present invention is not limited to this, and it is also possible to use a combination of pressed products such as the support member 02 shown in the related art. Further, the reinforcing member 5 may be formed with a constant cross section,
If the hanging portion 3c provided on the front end of the vehicle body is provided so as to be curved in conformity with the outer shape of the front portion of the vehicle body, the reinforcing member 5 also has
It may be formed in a shape curved in accordance with c. In this case, the left and right press dies are made separately, so that they cannot be used for the left and right sides. However, since the closed dies can be supported by increasing the closed cross section, the strength and rigidity can be increased. Further, even when the hanging portion 3c is curved, at least the connecting portions 53R and 53L provided on the hanging portion 3c are formed in a plane that is straight in the vehicle width direction, and the first box-shaped section is formed. By forming the connecting portions 52R and 52L provided on the 21 in a plane that is straight in the vehicle width direction, one reinforcing member 5 can be commonly used for the left and right. Also,
The coupling portions 5a and 5b formed on the reinforcing member 5 are not limited to the flange shape as shown in the embodiment,
The end face may be directly connected to the box section member 20 side.
