Abstract

PROBLEM TO BE SOLVED: To prevent an angle of an occupant's foot to leg from decreasing due to rising of a cover by the deformation of a toe board at the time of collision, and ease an impact acting upon the foot in a structure where a control box which houses an electronic control unit in the toe board is disposed, and formed so that his or her foot can be placed on the cover covering the disposing part of the box. SOLUTION: The torsional rigidity of a toe board 2 is increased by fixing the lower end and the upper end of a cover 6 on a floor panel 1 and a dash board 3 respectively, and forming a closed cross-section space ranging from the floor panel 1 to the dash board 3, between the cover 6 and the toe board 2. An impact absorbing member 8 is disposed between the cover 6 and a control box 5. A box wall which faces the cover of the control box or the cover may be formed into a corrugated sheet shape, or the cover may be formed into such a protruding shape as to swell to a cabin side.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a front plate of a passenger compartment of an automobile.

[0002]

2. Description of the Related Art A front plate portion of a vehicle compartment includes a toe board which rises obliquely forward from a floor panel of a vehicle body, and a dashboard which extends upward from an upper end of the toe board.

A control box having a built-in electronic control unit is arranged on a surface of the toeboard on the passenger compartment side, and a cover provided so as to cover an arrangement portion of the control box constitutes a footrest on which an occupant's foot is placed. Are also conventionally known. still,
The cover is fixed to the toe board.

[0004]

However, at the time of a head-on collision, the toe board may be deformed so as to be rotationally displaced rearward about the lower end thereof. When the toe board is deformed in this way, the cover fixed to the toe board rises from the forwardly inclined position, and the angle between the foot of the occupant placed on the cover and the shin is reduced. Further, even when the toe board is simply deformed backward without rotational displacement, an impact load acts on the occupant's foot from the toe board via the control box and the cover.

SUMMARY OF THE INVENTION In view of the above, the present invention provides a structure of a front panel of a vehicle cabin in which the cover can be prevented from standing up in the event of a collision and the impact applied to the occupant's foot can be reduced. The challenge is to do.

[0006]

Means for Solving the Problems In order to solve the above problems,
According to the present invention, a front plate portion of a cabin is constituted by a toe board rising diagonally forward from a floor panel of a vehicle body and a dashboard extending upward from an upper end of the toe board, and a surface of the toe board on the cabin side is provided. A control box with a built-in electronic control unit, and a footrest on which the occupant's foot rests with a cover provided to cover the arrangement part of the control box. Formed, the lower end and the upper end of the cover are fixed to the floor panel and the dashboard, respectively, and further, an impact absorbing member is arranged between the cover and the control box, or faces the cover of the control box. The box wall is formed in a corrugated shape, the cover is formed in a corrugated shape, or the cover is formed in a convex shape bulging toward the passenger compartment.

According to the present invention, a closed cross-sectional space from the floor panel to the dashboard is formed between the toeboard and the cover. Therefore, the torsional rigidity of the toe board is increased, and the upright of the cover due to the rotational displacement of the toe board at the time of collision is suppressed.

Further, if the impact absorbing member is provided as described above, the impact from the toe board is absorbed by the member,
In addition, if the box wall and cover of the control box are formed in a corrugated shape as described above, the box wall and cover are easily deformed, the shock is absorbed by the deformation, and the cover is formed in a convex shape as described above. Then, the gap between the cover and the control box is widened, and the impact is absorbed by the deformation of the toe board until the control box contacts the cover. Therefore, in any case, the impact acting on the occupant's foot is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, reference numeral 1 denotes a floor panel of an automobile body, which is a toe board 2 rising diagonally forward from a front end of the floor panel 1, and a dashboard 3 extending upward from an upper end of the toe board 2. The toeboard 2 and the dashboard 3 constitute a front plate portion of the vehicle compartment.

A metal control box 5 containing an electronic control unit 4 for controlling an engine and the like is arranged on a surface of the toe board 2 on the vehicle cabin side. Further, a metal cover 6 is provided so as to cover the arrangement portion of the control box 5, and the foot a of the occupant can be placed on the cover 6.

The control box 5 is provided with a seat plate 5a for sitting on the toe board 2, and a pin 7 planted on the surface of the toe board 2 on the vehicle interior side is fitted into each mounting hole formed in the seat plate 5a. The control box 5 is attached to the toe board 2.

The cover 6 is formed to extend from the floor panel 1 to the dashboard 3. A hollow boss-shaped leg 6a is provided on the back surface of the cover 6 to be in contact with the seat plate 5a, and the pin 7 is engaged with a pin hole formed at the tip of the leg 6a to position the cover 6, In this state, the lower end and the upper end of the cover 6 are fixed to the floor panel 1 and the dashboard 3 with screws or the like, respectively.

An impact absorbing member 8 is arranged between the cover 6 and the control box 5. As the shock absorbing member 8, an elastic material such as rubber or a plastic material such as hard urethane which is crushed by an impact load can be used. In the figure, reference numeral 9 denotes a floor carpet laid on the floor panel 1.

According to the above configuration, a closed sectional space from the floor panel 1 to the dashboard 3 is formed between the toe board 2 and the cover 6, so that the torsional rigidity of the toe board 2 is increased. As a result, during a head-on collision,
Is prevented from being deformed so as to be rotationally displaced rearward about the lower end thereof. Therefore, the rotation of the toe board 2 causes the cover 6 to stand up from a predetermined upwardly inclined position, thereby effectively preventing the angle between the occupant's foot a and the shin from being reduced.

At the time of a head-on collision, an impact acts on the occupant's foot a from the toe board 2 via the control box 5 and the cover 6, and this impact is caused by buckling of the leg 6a and deformation of the impact absorbing member 8. The shock acting on the foot a of the occupant is reduced by being absorbed.

Incidentally, even if the shock absorbing member 8 is not provided, FIG.
As shown in FIG. 3, the box wall 5b of the control box 5 facing the cover 6 is formed in a corrugated shape so that the box wall 5b is easily deformed, or as shown in FIG. If the cover 6 is formed so as to be easily deformed, when the box wall 5b abuts on the cover 6 due to the buckling of the leg 6a, the undulation of the box wall 5b or the undulation of the cover 6 is crushed and an impact is applied. It is absorbed and the impact acting on the occupant's foot a is reduced.

Further, as shown in FIG. 4, if the cover 6 is formed in a convex shape bulging toward the cabin, the gap between the cover 6 and the control box 5 is widened, and even if the leg 6a buckles. If the toe board 2 is not relatively deformed, the control box 5 will not come into contact with the cover 6. Therefore, the impact is absorbed by the deformation of the toe board 2 until the control box 5 contacts the cover 6, and the impact acting on the foot a of the occupant is reduced.

[0018]

As is clear from the above description, according to the present invention, it is possible to effectively prevent the cover from standing up at the time of a collision and the angle between the occupant's foot and the shin from being reduced. The impact acting on the occupant's foot can also be reduced.
