The present invention relates to an accelerator operating device.

[Prior art]

An accelerator operating device of a vehicle is configured such that an accelerator pedal and a throttle portion are connected by, for example, a wire cable, the throttle is opened by depressing the accelerator pedal, and the throttle is returned by a return spring if the accelerator pedal is not depressed.

As such a conventional technique, for example, JP-A-58-3692 is used.
The device disclosed in Japanese Patent No. 3 is disclosed.

[Problems to be solved by the device]

A person who is unfamiliar with a car or a beginner may accidentally step on the accelerator pedal while intending to step on the brake pedal in an emergency, and there is a problem that the vehicle accelerates in the opposite direction against the intention to try to brake.

Therefore, the object of the present invention is to ensure that when the accelerator pedal is mistakenly pressed against the brake pedal, braking is performed without accelerating and the following state is displayed to the follower to ensure safety. It is to provide an accelerator operating device according to the above.

[Means for Solving the Problems]

The accelerator operating interlock device of the present invention is an accelerator operating device for an automobile, in which an accelerator pedal and a throttle portion having a returning means are interlocked via a mechanical connecting means to open and close the throttle according to the amount of depression of the accelerator pedal. ,
In the path from the accelerator pedal to the throttle portion via the connecting means, the relatively formed substantially concave / convex portions are elastically fitted so that they can be disengaged according to the magnitude of the acting force. Is provided with a locking member and a locked member that are integrated with each other, and when the pedaling force applied to the accelerator pedal exceeds a predetermined value, the fitting state of the locking member and the locked member is released. Means for operating the throttle in the direction to return the throttle by the action of the restoring means regardless of the amount of depression of the accelerator pedal, and a display switch means for turning on the stop lamp and / or the hazard lamp when the safety means operates. It is characterized in that it is provided with.

[Action]

In normal operation, the force to depress the accelerator pedal is 3kg
It is about f. On the other hand, the force to depress the brake pedal in an emergency becomes 50 kgf or more.

Therefore, since the pedaling force applied to the accelerator pedal during a normal operation is less than a predetermined load (for example, 50 kgf), the accelerator pedal and the throttle portion are interlocked with each other, and the accelerator operation can be performed without any support.

However, if the accelerator pedal is strongly depressed by mistake for the brake pedal, a load larger than a predetermined value (for example, 50 kg
(f or more) is applied, the throttle is closed and the vehicle is braked (engine braked) without accelerating, thereby ensuring safety.

At this time, since the stop lamp does not light up because the brake pedal is not depressed, there is a risk that a following vehicle may collide with the vehicle. However, since at least one of the stop lamp and the hazard lamp is turned on by the display switch means even if the brake pedal is not depressed, it is possible to clearly indicate to the following vehicle that the vehicle is in the braking state and avoid the risk of a rear-end collision. .

It should be noted that the driver can immediately recognize that he / she misstepped the pedal by experiencing the above response, and can quickly perform normal operation again.

Here, FIG. 1 is a conceptual view of the configuration of an accelerator operating device according to an embodiment of the present invention in a normal state, FIG. 2 is a plan view of a main portion of the accelerator operating device shown in FIG. 1, and FIG. FIG. 4 is a bottom view of the main part of the accelerator operating device shown in FIG. 4, FIG. 4 is an end view taken along the line AA ′ in FIG. 1, and FIG. 5 is a view corresponding to FIG. FIG. 5 is a view corresponding to FIG. 1 showing a state at the time of safe operation, and FIG. 7 is a conceptual diagram showing the operation of the display switch means at the time of safe operation. The present invention is not limited to the embodiments described below.

The accelerator operating device 1 shown in FIG.
Is transmitted to the throttle cam S by the accelerator cable 3 (coupling means) to adjust the throttle opening of the carburetor C. Here, the accelerator pedal 2 and the accelerator cable 3 are connected by an accelerator operating connection device 11.

One end 12a of the first lever 12 of the accelerator operation coupling device 11 is attached to the tip of the accelerator pedal 2, and
The other end 13 b of the lever 13 is attached to the accelerator cable 3.

As shown in FIGS. 2 and 3, the other end 12b of the first lever 12 and the one end 13a of the second lever 13 are axially supported with respect to each other. Then, the other end 13b of the second lever 13
The locking member 14 is attached to the locking member 14, and the one end 12a side (the convex upper portion) of the first lever 12 (the locked member) is fitted into the V groove 14a (the concave upper portion) of the leg portion of the locking member 14. They are held together by elastic force and frictional force. This grip does not come off when the pedal force of the accelerator pedal 2 is less than 50 kgf, but comes off when it is 50 kgf or more.

As is apparent from FIG. 4, the contact pins 21a and 21b are insulated and attached to the leg portions of the locking member 14. These contact pins 21a and 21b are connected to the V groove 1
When the lever 12 is held by the 4a, the levers 12 do not come into contact with each other, and the lever 12 is disengaged so that the V-groove 14 can be moved by the elastic force of the legs.
When a is shortened, it comes into contact (see FIG. 7).

Therefore, the contact pins 21a and 21b function as switches and are provided in the circuit that connects the battery B with the stop lamp SL and the hazard lamp HL to form the display switch 20.

Now, in the state of FIG. 1 in which the one end 12a side of the first lever 12 and the other end 13b side of the second lever 13 are integrated, the throttle cam S of the carburetor C is rotated by depressing the accelerator pedal 2. It is possible to operate the throttle opening.

Therefore, as shown in FIG. 5, when the accelerator pedal 2 is fully depressed, the throttle cam S is rotated via the first lever 12, the locking member 14, the second lever 13 and the accelerator cable 3, and the throttle is released. Most opened

If the accelerator pedal 2 is not depressed, the carburetor C
The throttle cam S is returned to its original position by the return spring (returning means) of the accelerator cable 3, the second lever 13, the locking member 14, and the first lever 1.
The accelerator pedal 2 is returned to the original position via 2.

After all, the pedal force of the accelerator pedal is about 3 kgf in normal operation, and at this level, one end 12a of the first lever 12 is

When the accelerator pedal 2 is mistakenly pressed against the brake pedal and the vehicle does not decelerate, when a strong pedal force is applied to the accelerator pedal 2 such that the brake is further suddenly applied, the first force is applied against the elastic force and frictional force of the engaging member 14. The one end 12a of the lever 12 and the other end 13b of the second lever 13 are disengaged, and the first end 12a of the first lever 12 and the one end 13a of the second lever 13 are pivoted around the fulcrum. Lever 1
2 acts downward and the second lever 13 tends to act upward, so that the one end 12a of the first lever 12 and the other end 13b of the second lever 13 are disengaged,
The mechanical connection state is released and the device is separated.
FIG. 6 shows this state.

As will be understood from FIG. 6, in this state, the accelerator pedal 2 is depressed to a position where it comes into contact with the frame F, but the accelerator cable 3 on the carburetor C side is pulled back by the return spring, and the throttle is closed to a substantially idling state. .

Therefore, the vehicle is braked by the engine brake without accelerating.

Further, as shown in FIG. 7, the contact pins 21a, 2
Since the 1b contacts, the stop lamp SL and the hazard lamp HL are turned on.

Therefore, it is possible to clearly indicate to the following vehicle that it is in the braking state,
The danger of a rear-end collision can be prevented.

From the response of the vehicle, the driver can immediately recognize that he / she depresses the accelerator pedal 2 by mistake with the brake pedal, and can immediately perform correct operation again.

When reconnecting the separated one end 12a of the first lever 12 and the other end 13b of the second lever 13, the first lever 12
One end 12a of the above may be pushed into the V groove 14a of the locking member 14. The taper portion of the V groove 14a enables easy reconnection,

As another embodiment, a sleeve member, one of which is connected to a transmission member (coupling member) on the accelerator pedal side and the other of which is connected to the throttle portion side, and an inner member slidably inserted into the sleeve member. And a protrusion that elastically protrudes from one of the members in a direction substantially perpendicular to the insertion direction is fitted into the other recess so that both members are integrated and tension of a predetermined load or more is applied. When a force is applied, the fitting is disengaged against the elastic force so that the two members are separated from each other by interposing an accelerator operation coupling device in the middle of a transmission member that transmits the pedaling force applied to the accelerator pedal to the throttle portion. Another example is a safety switch, and a micro switch that is turned on when the operating member is opened by separating the sleeve member from the inner member is used as the display switch unit.

[Effect of device]

According to the present invention, in an accelerator operating device for an automobile, an accelerator pedal and a throttle portion having a returning means are interlocked with each other through a mechanical connecting means to open and close the throttle according to a depression amount of the accelerator pedal. Integrated by elastically fitting the relatively formed substantially concave / convex portions so that they can be disengaged according to the magnitude of the acting force, in the path from the connecting part to the throttle part through the connecting means. When the accelerator pedal is provided with a locking member and a locked member, and the pedaling force applied to the accelerator pedal exceeds a predetermined level, the fitting state between the locking member and the locked member is released to release the accelerator pedal. Irrespective of the amount of depression of the vehicle, the safety means operates to close the throttle by the action of the return means, and a stop lamp and / or a hazard when the safety means operates. There is provided an accelerator operating device for an automobile, which is provided with a display switch means for turning on a lamp, which allows the accelerator to be operated from low speed to high speed without any trouble in normal operation, and can be used as a brake pedal. If you accidentally step on the accelerator pedal with a strong pedal force, regardless of how much you step on the pedal, it will respond promptly to the braking based on a relatively simple mechanical structure, which will prevent the vehicle from moving at an unexpectedly high speed. . In addition, since the fact that the vehicle is in the braking state is clearly indicated by the lamp, it is possible to prevent a rear-end collision of a following vehicle.

Further, when the safety means is returned after the operation, the stop member and the locked member only need to be elastically re-fitted, and the function is extremely practical.
