Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an accelerator pedal mounting structure, and more particularly to an accelerator pedal mounting structure for displacing an accelerator pedal forward when a load is input from the front of a vehicle body.

[0002]

2. Description of the Related Art As shown in FIG. 6, a conventional accelerator pedal mounting structure is such that an intermediate portion of an accelerator lever 22 having an accelerator pedal 21 fixed to a lower end is rotated by an accelerator bracket 23 mounted on a dash panel 20. The accelerator cable 2 is supported freely on the upper end of the accelerator lever 22.
4 are connected.

Japanese Patent Application Laid-Open No. Hei 8-132916 discloses that the accelerator cable is pulled out as the accelerator lever moves due to the backward movement of the mounting portion of the accelerator bracket when the toeboard is deformed, thereby increasing the accelerator pedal depression amount. In order to prevent a situation from occurring, an upper part that sets the initial depression amount of the accelerator cable and a T-shaped plate that extends downward from this upper part are provided, and the lower end is pivotally supported by the accelerator bracket Is disclosed.

[0004]

However, in the conventional configuration as shown in FIG. 6, when a load is input from the front of the vehicle body,
As shown in FIG. 7B, the accelerator pedal 21 connected to the accelerator bracket 23 moves backward from the normal state of FIG. 7A as the dash panel 20 enters the vehicle interior. Therefore, it is desired to develop a configuration in which the accelerator pedal 21 is displaced forward to increase the foot space when a load is input.

In Japanese Unexamined Patent Publication No. Hei 8-132916, since the dash panel is restricted by the upper portion of the T-shaped plate even if it moves backward, the amount of pulling of the accelerator cable does not increase. However, there is a problem that the cost is increased because parts having a complicated shape and structure are required.

The present invention has been made in view of the above-mentioned conventional problems, and provides an accelerator pedal mounting structure capable of displacing an accelerator pedal forward at the time of load input and preventing an increase in the amount of pulling of an accelerator cable with a simple configuration. Aim.

[0007]

An accelerator pedal mounting structure according to the present invention comprises an accelerator bracket having an accelerator lever having an upper end to which an end of an accelerator cable is connected and an accelerator pedal fixed to a lower end fixed to a vehicle body. In an accelerator pedal mounting structure rotatably supported by an accelerator, an accelerator bracket is disposed on a floor, an accelerator lever is pivotally supported on the accelerator bracket, and a tip end of the accelerator lever or a position in the vicinity thereof, or a vehicle body facing the position The side portion is provided with a projection which comes into contact with the dash panel or the accelerator lever when the dash panel is deformed.

[0008] With this configuration, the accelerator bracket does not move rearward as much as when the accelerator bracket is disposed on the dash panel at the time of load input, while the movement of the dash panel causes the upper end of the accelerator lever via the projection. The part is pushed rearward to move, and the accelerator pedal can be relatively moved forward by the rotation of the accelerator lever. In addition, since the protrusion is arranged near the tip of the accelerator lever, an increase in the amount of pulling of the accelerator cable when a load is input can be reduced.

[0009] The floor includes a tire house or the like protruding toward the passenger compartment side. If an accelerator bracket is disposed above the tire house, the rigidity is higher than that of a floor in a narrow sense. Therefore, a special reinforcing member must be provided. The low-cost configuration allows the accelerator pedal to be displaced forward,
Further effects are exhibited.

If the distance between the pivotal position of the accelerator lever and the coupling position of the accelerator cable is A, and the distance between the pivotal position of the accelerator lever and the projection is B, B> A,
In the case of B <A, when the accelerator lever is rotated via the projection with the movement of the dash panel at the time of load input, the amount of pulling of the accelerator cable increases, but the projection comes into contact with the accelerator lever. Therefore, the accelerator cable is not pulled out when rotating, and the increase in the amount of pulling of the accelerator cable at the time of load input can be reliably prevented at low cost.

[0011] Further, a connecting piece whose leading end is coupled to the dash panel from the highly rigid portion of the accelerator bracket is connected via a weak portion, and the connecting piece is provided with a projection which comes into contact with the accelerator lever when the dash panel is deformed. Since the accelerator bracket is provided across the dash panel and the high rigidity part, the support rigidity of the accelerator bracket during normal operation is increased, and the connecting piece is deformed by the fragile part as the dash panel moves during load input. While the position of the pivot of the accelerator lever is held without an excessive load acting on the high rigid part, the upper end of the accelerator lever moves backward through the projection,
The accelerator pedal at the lower end of the accelerator lever can be relatively moved forward.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an accelerator pedal mounting structure according to the present invention will be described below with reference to FIGS.

In FIGS. 1 and 2, reference numeral 1 denotes a vehicle compartment, 2 denotes a dash panel forming a lower part of the front surface, and 3 denotes a floor panel forming a floor surface. Reference numeral 4 denotes a rear portion of the front wheel tire house protruding from the lower front end of the vehicle compartment 1.

An accelerator lever 5 has an upper end to which an end of an accelerator cable 6 is connected, and an lower end to which an accelerator pedal 7 is fixed. The accelerator cable 6 penetrates through the dash panel 2 and is guided through a casing fixed to the dash panel 2 to be connected to a throttle valve of the engine. The accelerator lever 5 has an intermediate portion rotatably supported via a pivot shaft 9 by an accelerator bracket 8 formed of sheet metal so as to have a required rigidity. The accelerator bracket 8 is fastened and fixed to the inner end of the upper surface of the tire house 4 in the vehicle width direction. One end 9a of the pivot shaft 9 is protruded inward from the accelerator bracket 8 in the vehicle width direction. The accelerator lever 5 is fixedly or rotatably supported by the portion 9a.

A stopper 10 extending toward the dash panel 2 is provided at a position near the tip of the accelerator lever 5, that is, near a position where the accelerator cable 6 is connected, and a stopper receiving portion having a tip formed on the dash panel 2. 11. A coil spring 12 having one end engaged with the accelerator lever 5 and the other end engaged with the accelerator bracket 8 is wound around the outer periphery of one end 9a of the pivot shaft 9, and the stopper 10 is provided with a stopper receiving portion. The accelerator lever 5 is rotationally biased so as to come into contact with the accelerator lever 11. Thus, the initial position of the accelerator lever 5 is set with the stopper 10 in contact with the stopper receiving portion 11. The upper portion of the accelerator lever 5 extends obliquely upward toward the outside in the vehicle width direction so as to avoid interference with the brake booster arrangement portion 13 of the dash panel 2.

In the above configuration, the tire house 4 is a portion that is less liable to be deformed when a load is input than the dash panel 2 at the lower front end of the vehicle interior of the vehicle body, and the tire house 4 is provided with an accelerator bracket 8 having a required rigidity. Since it is fixed, the accelerator bracket 8 does not largely move backward even when a load is input. On the other hand, the upper end of the accelerator lever 5 is pushed rearward via the stopper 10 as the dash panel 2 largely deforms and moves rearward when a load is input, whereby the accelerator lever 5 moves the accelerator bracket 8 of the accelerator bracket 8. By rotating around the pivot 9, the accelerator pedal 7 relatively moves forward.

Referring to FIG. 3, when the dash panel 2 starts to be deformed by a load input from the front of the vehicle from the initial state shown by the virtual line O, as shown by the solid line P,
When the upper part of the accelerator lever 5 moves backward through the stopper 10 while the accelerator bracket 8 and the pivot shaft 9 hardly move, the accelerator pedal 7 largely moves forward, and the accelerator pedal 7 moves forward from the initial state. Is held in the position.

Thus, even when the dash panel 2 moves backward, the accelerator pedal 7 moves forward from the initial state. Further, by disposing the accelerator bracket 8 on the tire house 4, the accelerator pedal 7 can be displaced forward with a low-cost configuration without providing a special reinforcing member for the dash panel 2.

The stopper 10 is connected to the accelerator cable 6
Therefore, even if the accelerator lever 5 is rotated via the stopper 10 with the movement of the dash panel 2 at the time of load input, the amount of pulling out of the accelerator cable 6 from the initial position is small. An increase in the amount of pulling of the cable 6 can be reliably prevented.

In the above description, the stopper 10 is provided so as to extend from the accelerator lever 5, but may be provided on the dash panel 2 side.

Next, another embodiment of the accelerator pedal mounting structure of the present invention will be described with reference to FIG. In the following embodiments, the same components as those in the above embodiment are denoted by the same reference numerals, and description thereof will be omitted. Only different points will be described.

The accelerator bracket 14 of the present embodiment is
As shown in FIG. 4A, a connecting piece 16 whose tip is coupled to the dash panel 2 from a highly rigid portion 15 supporting the pivot 9 is connected to the dash panel 2 via a weak portion 17. ing. Then, a stopper 18 is provided which comes into contact with the accelerator lever 5 from near the distal end of the connecting piece 16 and sets its initial position.

In the configuration of the present embodiment, since the accelerator bracket 14 is disposed so as to straddle between the dash panel 2 and the tire house 4, the support rigidity of the accelerator bracket 14 is high, and FIG. As shown in the figure, when a load is input from the front of the vehicle body, the dash panel 2
As the fragile portion 17 is deformed and the connecting piece 16 is moved rearward as the vehicle moves backward, an excessive load does not act on the highly rigid portion 15 fixed to the tire house 4 which is difficult to deform, While the position of the pivot portion of the accelerator lever 5 supported by the high rigidity portion 15 is maintained, the upper end of the accelerator lever 5 moves rearward via the stopper 18, so that the accelerator pedal at the lower end of the accelerator lever 5 is moved. 7 relatively moves forward.

Next, still another embodiment of the accelerator pedal mounting structure of the present invention will be described with reference to FIG.

In the above embodiment, the example in which the stoppers 10 and 18 are provided on the accelerator lever 5 or the accelerator bracket 14 has been described. In the present embodiment, the stopper 19 is provided on the dash panel 2 side. And the accelerator lever 5
The distance between the axis position of the pivot shaft 9 and the coupling position of the accelerator cable 6 is A, and the axis position of the pivot shaft 9 and the stopper 19
B is set to be B> A, where B is the distance from the tip of the target.

According to the present embodiment, even if the accelerator lever 5 is rotated via the stopper 19 with the movement of the dash panel 2, since B> A, the accelerator cable 6 is set. Is not pulled out from the initial position, and the increase in the amount of pulling of the accelerator cable 6 at the time of load input can be reliably prevented at low cost.

In the above description, an example is shown in which the stopper 19 is provided on the dash panel 2 side. However, it goes without saying that the stopper 19 may be provided to extend from the accelerator lever 5 in this embodiment.

In each of the above embodiments, the stoppers 10, 18, 19 for setting the initial position of the accelerator lever 5 are provided.
Is used as a projection for displacing the accelerator pedal 7 forward when a load is input, thereby reducing the number of components. However, it is needless to say that the stopper for setting the initial position and the projection may be separate components.

[0029]

According to the accelerator pedal mounting structure of the present invention, the accelerator bracket is disposed on the floor as described above, and the accelerator lever is pivotally supported on the accelerator bracket. Alternatively, a projection that contacts the dash panel or the accelerator lever when the dash panel is deformed is provided on the vehicle body side facing the position, so that the accelerator bracket can be moved rearward greatly as if the accelerator bracket was arranged on the dash panel. On the other hand, as the upper end of the accelerator lever is pushed backward through the projection by the movement of the dash panel and moves backward, the accelerator pedal can be relatively moved forward and conversely, increasing the foot space. be able to. In addition, since the protrusion is arranged near the tip of the accelerator lever, an increase in the amount of pulling of the accelerator cable when a load is input can be reduced.

If the distance between the pivot position of the accelerator lever and the coupling position of the accelerator cable is A, and the distance between the pivot position of the accelerator lever and the projection is B, and B> A,
When the projection is brought into contact with the accelerator lever and turned, the accelerator cable is not pulled out by this, and it is possible to reliably prevent an increase in the amount of pulling of the accelerator cable at the time of load input at low cost.

Further, a connecting piece whose leading end is connected to the dash panel from the highly rigid portion of the accelerator bracket is connected to the dash panel via a weak portion, and the connecting piece is provided with a projection which comes into contact with the accelerator lever when the dash panel is deformed. Since the accelerator bracket is provided over the dash panel and the high rigidity part, the support rigidity of the accelerator bracket is increased, and the position of the pivot of the accelerator lever can be adjusted without applying an excessive load to the high rigidity part at the time of load input. While being held, the upper end of the accelerator lever moves rearward via the projection, and the accelerator pedal at the lower end of the accelerator lever can be relatively moved forward.
