Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an accelerator pedal device for an automobile.

The structure of conventional accelerator pedal devices includes the so-called organ type, in which one end of the pedal is pivoted to the floor, and the pendant type, which is a hanging type.However, in the organ type, the pedal is installed on the floor, so foot space is narrowed. There were other problems, such as difficulty in getting in and out of the vehicle, and difficulty in cleaning the inside of the vehicle. By adopting a pendant type structure, the problems of the organ type are solved, but
In the pendant type, the pedal is fixed at a fixed angle to the lower end of a hanging arm that is pivoted upward, and the angle of the pedal surface relative to the sole of the foot inevitably changes depending on the amount of depression, resulting in long-term operation. In addition, there was a fear that the foot would come off the pedal surface.

The present invention was made to solve the above problems, and its purpose is to configure the pedal so that the angle of the pedal surface and the angle of the sole of the foot always match regardless of the amount of pedal depression. Therefore, an object of the present invention is to obtain an accelerator pedal device which reduces fatigue even when used frequently for a long period of time.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

In FIGS. 1 and 2, 1 is a body, and 2 is a hollow bracket with an L-shaped side surface, a required width, and an opening at the bottom. The bracket 2 is attached to the body 1 with bolts 2a. , 3 is a substantially triangular link body whose center portion is pivotably pivoted to the upper part of the bracket 2 by a pin 4;
Similarly, there is a bracket piece having a U-shaped cross section, which is rotatably pivoted in the middle of the bracket 2 by means of a pin 6. 7 has two vertical walls 7 on the back side of the footboard portion 7a.
This is a pedal equipped with b and 7b. The first arm 8 is made of a metal round bar, and includes a main body 8a formed in a substantially L-shape, and a main body 8a extending from both ends of the main body 8a.
The end portions 8b and 8b' are bent and extended by a predetermined amount in the same direction at right angles to the end portions 8b and 8b'. On the other hand, the second arm 9 is formed from a metal round bar similar to the first arm 8, and has a main body 9a formed in a straight line.
and end portions 9b, 9 which are bent and extended by a predetermined amount in opposite directions from both ends at right angles to the main body 9a.
It consists of b′. An accelerator wire 10 connected to an engine acceleration device is attached to one end of the link body 3 closer to the body. The first arm 8 is the main body 8a
The vicinity of the L-shaped bent part is fixed to the U-shaped cross section of the bracket piece 5, the distal end 8b is pivoted to the vicinity of the tread part 7a of the vertical walls 7b, 7b of the pedal 7, and the base end side The end portion 8b is a long hole 3 provided at the other end of the link body 3 on the opposite side to the side where the accelerator wire 10 is engaged.
engages a. The second arm 9 is the first arm 8
body 1 from the first arm 8 at a predetermined distance from the
The distal end 9b of the second arm 9 is connected to the first vertical wall 7b of the pedal 7.
The arm 8 is pivoted below the arm 8, and the proximal end 9
b' is pivotally connected to the bracket 2 below the pin 6 of the bracket piece 5. A stopper 11 is attached to the body 1 and limits the amount by which the pedal 7 is depressed. The bracket 2, the first and second arms 8, 9, and the pedal 7 form a four-bar link.

By configuring the present invention in this way, when the pedal 7 is depressed from the free state shown by the two-dot chain line in FIG. 6 and the second arm 9 pivot downward around the proximal end 9b', the accelerator wire 10 is pulled upward, and the engine accelerator is activated. In this case, by determining the pivoting positions of the first and second arms 8, 9 with the bracket 2 and the pedal 7, the tread surface of the pedal 7 is approximately aligned with the plane passing through the pivot point A on the sole of the foot. The contact point of the sole of the foot with the pedal always matches the angle of the pedal tread surface with the angle of the sole of the foot, and both contact points are kept at approximately the same position, so it can be used for long periods of time. Even during frequent use, the level of fatigue is reduced, and moreover, the foot does not come off the pedal tread.
