JPH05181557A - Accelerator misoperation prevention device for automobile - Google Patents

Abstract

PURPOSE:To immediately stop the motion of an accelerator pedal which is mis-stepped for a brake pedal suddenly and to prevent a rear-end collision by instantaneously displacing a lower rotary body by a take-up tool and pressing it against an upper rotary body when an impulsive gravitational force which is larger than a certain force is applied to the accelerator pedal. CONSTITUTION:The lower rotor 5 is fitted through a shaft 6 at the lower part of a housing 1 and the shaft 6 is energized downward by a spring 8 and can freely move up and down in a longitudinal groove 7. When the accelerator pedal 14 is stepped in, the take-up member 11 such as a belt connected to the fixture 13 of an arm 14a is drawn, so that the lower rotor 5 and upper rotor 2 are associated with each other. When the pedal 14 is released, on the other hand, the take-up member is rewound by the quantity of the extension by the take-up spring 4. Thus, normal operation is smoothly done, but if the pedal 14 is stepped suddenly by mistake as the brake pedal, the spring 8 is drawn unnecessarily by inertia and the lower rotor 5 is drawn to the upper rotor 2 to make hard-to-slide members 9 and 10, which rotate in opposite directions, engage each other, thereby instantaneously stopping the motion.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when the accelerator pedal of an automobile is mistaken for a brake pedal and is suddenly depressed,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an accelerator erroneous operation prevention device for an automobile that instantly stops the accelerator pedal.

[0002]

2. Description of the Related Art Conventionally, as a method for preventing an erroneous operation of an accelerator operation of an automatic automobile or the like, it has been impossible to switch unless a brake is stepped every time a gear is switched. This was based on the idea that the start was a break.

[0003]

The malfunction of the accelerator operation of an automatic automobile or the like occurs due to the driver's feelings when starting, driving or stopping. Even with a mechanism in which the gear cannot be entered unless the brake is stepped on, the brake and accelerator pedal are suddenly activated during operation when gear change has already been completed or when the vehicle is stopped due to a quick response to the driver's discomfort. There is a problem in that an operation of stepping on by mistake occurs.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and an upper rotation made of a non-slip material biased by a spring in an upper part of a housing fixed to a vehicle body above an accelerator pedal. A body is pivotally mounted, and a lower rotating body made of a material that is hard to slip is disposed below the rotating body so as to be vertically movable, and the lower rotating body is held at a predetermined distance from the rotating body by a spring or a magnet. When a belt, string, or other winding member fixed to the accelerator pedal is wound around the shaft, lower rotating body, or upper rotating body, and the impact force applied to the accelerator pedal exceeds a certain level, the winding tool instantly rotates the lower rotating body. It is characterized in that it is displaced upward to press the lower rotary body against the upper rotary body, and to instantaneously stop the depression of the accelerator pedal.

[Embodiment] Case 1 fixed to the vehicle body above the accelerator pedal
An upper rotor-2 is fixed to the inner upper portion through a shaft 3. A winding spring 4 is attached to one end of the shaft 3. A lower rotor 5 is attached to the lower part of the housing 1 so as to face the upper rotor-2 through a shaft 6, and the shaft 6 is pulled downward by a spring 8. The shaft 6 can freely move up and down in the vertical groove 7. Further, non-slip members 9 and 10 such as gears, rubber and resin are provided at both ends of the upper rotor-2 and the lower rotor 5 so as to mesh with each other when an impact force is applied and a tensile force is generated. Has been.

On the upper rotor-2, a winding member 11 such as a belt, a cord or a wire is wound several times in conjunction with the winding spring 4, one end of which is fixed to the upper rotor-2. The other end extends around the lower rotor 5 and is wound around the shaft 12 so that it half-circulates around the shaft 12 and is attached to the arm 14a of the accelerator pedal 14 by a mounting member 13.

Next, the operation will be described. When the accelerator pedal 14 is stepped on, the winding member 11 such as a belt, a cord, and a wire connected to the fitting 13 attached to the arm 14a is pulled to pull the shaft 12, the lower rotor 5, and the upper rotor. -Ta-2 works together.

When the accelerator pedal 14 is released, it is rewound by the amount taken out by the winding spring 4. In this way, in normal pedal operation, this interlocking operation is smoothly repeated, but if the accelerator pedal 14 is accidentally depressed by mistake as a brake pedal, the spring 8 is unnecessarily pulled by the action of inertia. The lower rotor 5 is the upper rotor.
The upper rotor 2 and the lower rotor 5 are attracted to each other instantaneously, and since the upper rotor 2 and the lower rotor 5 are rotating in opposite directions, the non-slip members 9, 10 such as gears, rubber, resin, etc. which face each other It meshes with each other and the movement stops momentarily.

[0009]

According to the present invention, an upper rotating body made of a non-slip material urged by a spring is pivotally attached to an upper part of a housing fixed to a vehicle body above an accelerator pedal, and a lower non-slip material is made of the non-slip material. A winding member, such as a belt or a string, which is fixed to an accelerator pedal, in which vertically arranged lower rotating bodies are arranged so as to oppose each other, and the lower rotating bodies are held at a predetermined distance from the rotating bodies by springs or magnets. When the accelerator pedal is wound around the shaft, the lower rotary body, and the upper rotary body, and the impact force exceeds a certain level, the winding tool instantly displaces the lower rotary body upward, and the lower rotary body becomes the upper rotary body. As it is pressed, the accelerator pedal is stopped instantly, so
While the accelerator pedal is being operated normally, you can smoothly step on it as before, but if you accidentally step on the accelerator pedal by mistakenly thinking that it is a brake, you can instantly stop the movement of the accelerator pedal, resulting in a rear-end collision accident. Can be reliably prevented.
