Description

  The present invention relates to an accelerator pedal device for a vehicle that increases play of an accelerator pedal operation in conjunction with a brake pedal operation.

  In the vehicle, an accelerator pedal and a brake pedal are arranged side by side, and the accelerator pedal that is depressed by the driver when accelerating the vehicle transmits the depression operation to the throttle lever of the engine via the throttle cable. Then, the throttle valve is opened by the throttle lever, the engine speed is increased, and the vehicle is accelerated.

  Here, the throttle cable is composed of a pipe-shaped outer cable and an inner wire that is slidably inserted therein, and the operation of the accelerator pedal is transmitted to the throttle lever by the inner wire. That is, one end of the inner wire is connected to the accelerator pedal arm, and the other end is connected to the throttle lever. The outer cable has one end fixed to the vehicle body panel near the accelerator pedal arm and the other end fixed to a component near the throttle lever.

  Thus, when the driver depresses the accelerator pedal, the inner wire with one end connected to the accelerator pedal arm is pulled out from the outer cable, and the inner wire is pulled into the outer cable at the other end of the throttle cable. The throttle lever connected to moves and the throttle valve opens.

  In the above-described conventional accelerator pedal device, the throttle (engine speed) is adjusted only by operating the accelerator pedal regardless of the operating state of the brake pedal. For example, the driver mistakenly presses the brake pedal and the accelerator pedal at the same time. If the vehicle is depressed, there is a possibility that the deceleration of the vehicle may be delayed even though the driver depresses the brake pedal with the intention of decelerating the vehicle.

  In order to solve the above problems, Patent Documents 1 and 2 propose a configuration in which the accelerator operation is mechanically canceled in conjunction with the depression of the brake pedal. The stepping motion of is absorbed by the extension of the spring.

Japanese Utility Model Publication No. 64--029032 Japanese Utility Model Publication No. 6-045833

  However, in the configurations proposed in the above cited references 1 and 2, the structure becomes complicated, and in the state where the brake pedal is depressed, the accelerator pedal depressing operation is not transmitted to the throttle lever, so that the accelerator operation is impossible. There was a problem that the accelerator operation while stepping on the brake pedal was impossible when starting on a slope, which was inconvenient in practice.

  In addition, since the structure in which the depression operation of the accelerator pedal is absorbed by the extension of the spring is adopted, there is a problem that the reaction by the spring returns to the driver as a reaction force of the brake pedal, and the brake operation becomes heavy.

  SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and the object of the present invention is to provide a vehicle capable of preventing a delay in deceleration of the vehicle when operating the brake pedal with a simple configuration and operating the accelerator when depressing the brake pedal. An accelerator pedal device is provided.

  In order to achieve the above object, the invention according to claim 1 is an accelerator pedal device for a vehicle in which an accelerator pedal arm and an engine throttle lever are connected by a throttle cable, and the engine speed is controlled by depressing the accelerator pedal. The throttle cable is composed of a pipe-shaped outer cable and an inner wire that is slidably inserted into the pipe. The accelerator pedal arm and one end of the inner wire of the throttle cable are connected so as to be relatively movable, and the outer cable The end of the accelerator pedal arm is configured to be movable in accordance with the operation of the brake pedal, and the outer cable is moved in a direction in which the play of the accelerator pedal operation increases in response to the depression of the brake pedal.

  According to a second aspect of the present invention, in the first aspect of the present invention, the outer cable and the inner wire are integrally moved by depressing the brake pedal, and the inner wire is moved relative to the accelerator pedal arm. A play is formed between the connecting end of the wire and the accelerator pedal arm.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, a push pin projects from the longitudinal intermediate portion of the brake pedal arm whose upper end portion is pivotally supported by the vehicle body. An outer cable moving mechanism is configured by connecting one end of a holder lever pivotally supported by the vehicle body to one end of the outer cable and engaging the other end with the push pin. .

  According to a fourth aspect of the present invention, in the first or second aspect of the present invention, the upper end portion of the brake pedal arm that is pivotally supported on the vehicle body by the swing shaft so as to be swingable is disposed above the swing shaft. The outer cable moving mechanism is configured by connecting the cable to one end of the outer cable.

  According to the first aspect of the present invention, since the outer cable is moved in the direction in which the play of the accelerator pedal operation increases by depressing the brake pedal, the driver accidentally depresses the brake pedal and the accelerator pedal at the same time. However, first, only the operation of the brake pedal is enabled, the vehicle is immediately decelerated, and there is no delay in deceleration. And if you depress the accelerator pedal more than the amount of play while depressing the brake pedal, the accelerator operation becomes possible, so you can operate the accelerator while depressing the brake pedal when starting a slope, etc. It is not accompanied. In addition, since the system that absorbs the depression of the accelerator pedal by the extension of the spring is not adopted, the reaction by the spring does not return to the driver as the reaction force of the brake pedal, and the brake operation becomes heavy. Nor.

  Thus, the above effect can be obtained by a simple configuration in which the end portion of the outer cable on the accelerator pedal arm side is configured to be movable according to the operation of the brake pedal.

  According to the second aspect of the present invention, the inner wire is moved together with the outer cable by the depression operation of the brake pedal. However, the inner wire moves relative to the accelerator pedal arm and affects the accelerator pedal arm. Therefore, even if the brake pedal is operated while the accelerator pedal is not depressed, the accelerator pedal remains stationary and does not give the driver a sense of incongruity. Further, since the inner wire does not push the accelerator pedal arm, an excessive force is not applied to the inner wire, and the durability thereof is enhanced.

  According to the invention of claim 3, when the brake pedal is depressed, the push pin protruding from the brake pedal arm swings the holder lever, and the outer cable is drawn together with the inner wire by the swing of the holder lever. Since the inner wire slides with respect to the accelerator pedal arm, a play is formed between the connecting end of the inner wire and the accelerator pedal arm, and the play of the accelerator pedal operation when the brake pedal is operated increases.

  According to the fourth aspect of the present invention, when the brake pedal is depressed, the outer cable connected to the upper end of the brake pedal arm is drawn together with the inner wire, and the inner wire slides with respect to the accelerator pedal arm. A play is formed between the connecting end of the wire and the accelerator pedal arm, and the play of the accelerator pedal operation when the brake pedal is operated increases.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

<Embodiment 1>
FIG. 1 is a perspective view showing a configuration of an accelerator pedal device according to Embodiment 1 of the present invention, and FIG. 2 is a side view of the accelerator pedal device.

  As shown in FIG. 1, an accelerator pedal 1 and a brake pedal 2 are arranged side by side at the foot of the driver's seat of the vehicle. The brake pedal 2 is attached to the lower end of the brake pedal arm 6 that is supported by the vehicle body by the swing shaft 5 so that the upper end of the brake pedal 2 is swingably supported.

  The accelerator pedal arm 4 transmits the stepping operation to a throttle lever of an engine (not shown) via a throttle cable 7 when the driver steps on the accelerator pedal 1 attached to the lower end thereof. By opening a throttle valve (not shown), the engine speed is increased and the vehicle is accelerated.

  Here, the throttle cable 7 is composed of a pipe-shaped outer cable 7a and an inner wire 7b that is slidably inserted into the outer cable 7a. The depression operation of the accelerator pedal 1 is transmitted to the throttle lever by the inner wire 7b. The

  Thus, a piece-like connecting member 8 is fixed to one end of the inner wire 7b on the accelerator pedal arm 4 side, and the rectangular groove 4a formed on the upper end portion of the accelerator pedal arm 4 has the inner wire 7b. A portion exposed from the outer cable 7a is slidably passed. In the state shown in FIG. 2 in which neither the accelerator pedal 1 nor the brake pedal 2 is operated, the upper end portion of the accelerator pedal arm 4 is in contact with the connecting member 8 fixed to the end portion of the inner wire 7b. At this time, the inner wire 7b is kept in a state exposed by a predetermined length from the outer cable 7a.

  The other end of the inner wire 7b is connected to a throttle lever (not shown) of the engine. When the accelerator pedal 1 is not depressed as shown in FIG. 2, the throttle valve that is opened and closed by the throttle lever is fully closed. In the state (idle opening), the engine is rotating at a low idle speed.

  Incidentally, a holder lever 9 is disposed in the vicinity of the upper portions of the accelerator pedal arm 4 and the brake pedal arm 6, and the holder lever 9 is provided with levers 9b and 9c at both ends of a swing shaft 9a disposed in the vehicle width direction. , Each of which is formed in the shape of a reverse letter when viewed from the side, and an intermediate portion thereof is swingably attached to the vehicle body by a swing shaft 9a. The upper end of the upper lever 9 b of the holder lever 9 is attached to one end of the outer cable 7 a of the throttle cable 7 on the accelerator pedal arm 4 side, and the lower end of the lower lever 9 c is connected to the brake pedal arm 6. Is engaged with a round pin-like push pin 10 that protrudes horizontally toward the accelerator pedal arm 4 side. The other end of the outer cable 7a is fixed to a component (not shown) disposed in the vicinity of the throttle lever. The swinging shaft 9a of the holder lever 9 is disposed at a position higher than the swinging shaft 3 of the accelerator pedal 1 and at a position to be pulled away from the swinging shaft 5 of the brake pedal 2, and is a small-sized in consideration of the acting direction of force. Placement is possible.

  As shown in FIG. 1, a return spring 11 is wound around the swing shaft 9a of the holder lever 9, and this return spring 11 pushes the outer cable 7a back to the throttle lever side (front of the vehicle) ( The holder lever 9 is urged in the clockwise direction in FIG. 2 around the swing shaft 9a, and the brake pedal arm 6 is moved to the initial position (the non-operation shown in FIG. 2) by the return spring 11 via the holder lever 9. The position is biased in the direction of returning to the position) (clockwise in FIG. 2 about the swing shaft 5). Here, the urging force of the return spring 11 is set to a value sufficiently larger than the pulling force of the inner wire 7b by the depression operation of the accelerator pedal 1.

  In the accelerator pedal device configured as described above, in the state shown in FIG. 2 in which neither the accelerator pedal 1 nor the brake pedal 2 is operated, erroneous operation such as erroneous depression of the accelerator pedal 1 and the brake pedal 2 or simultaneous depression is prevented. Therefore, the brake pedal 2 is disposed above the accelerator pedal 1, and a step L shown in the drawing is provided between them.

  Next, the operation of the accelerator pedal device according to the present invention will be described with reference to FIGS. 3 is a side view showing a state of the accelerator pedal device during an accelerator operation, FIG. 4 is a side view showing a state of the accelerator pedal device during a brake operation, and FIG. 5 is a brake operation and an accelerator operation of the accelerator pedal device. It is a side view which shows the state which performed simultaneously.

  For example, when the driver depresses the accelerator pedal 1 from the state shown in FIG. 2 in order to accelerate the vehicle, the accelerator pedal arm 4 moves in the direction indicated by the arrow (counterclockwise) around the swing shaft 3 as shown in FIG. ) From the position of the broken line to the position of the solid line, the upper end engages with the connecting member 8 and the inner wire 7b of the throttle cable 7 is pulled out from the outer cable 7a in the direction of the arrow shown in FIG. Then, the throttle valve is opened, and the vehicle is accelerated because the engine speed increases. In this case, since the urging force of the return spring 11 is set to a value sufficiently larger than the pulling force of the inner wire 7b by the depression operation of the accelerator pedal 1 as described above, the depression operation of the accelerator pedal 1 is set to the inner wire 7b. Can be reliably transmitted to the throttle lever.

  When the driver depresses the accelerator pedal 1 and depresses the brake pedal 2 to decelerate or stop the vehicle, the brake pedal arm 6 moves in the direction indicated by the arrow about the swing shaft 5 as shown in FIG. It swings from the broken line position to the solid line position (clockwise), thereby operating a brake device (not shown) to decelerate or stop the vehicle. At this time, a push projecting from the brake pedal arm 6 The pin 10 abuts on the holder lever 9 and swings the holder lever 9 from the broken line position to the solid line position in the illustrated arrow direction (counterclockwise direction) about the swing shaft 9a. Then, the holder lever 9 pulls the outer cable 7a of the slot cable 7 together with the inner wire 7b in the direction of the arrow shown. That is, the swing of the holder lever 9 moves the outer cable 7a in the direction in which the inner wire 7b is pulled out. More specifically, the swing of the holder lever 9 moves the outer cable 7 a in a direction approaching the upper end of the accelerator pedal arm 4.

  Here, as described above, the inner wire 7b is passed through the groove 4a (see FIG. 1) formed at the upper end of the accelerator pedal arm 4, and is movable with respect to the throttle pedal arm 4. The inner wire 7b is pulled out in the illustrated arrow direction together with the outer cable 7a while maintaining the state 4 (non-operating state) as it is. Then, the illustrated play a is formed between the connecting member 8 fixed to the end of the inner wire 7b and the upper end of the throttle pedal arm 4, and this play a increases in proportion to the amount of depression of the brake pedal 2. To do.

  At this time, the inner wire 7 b slides in a rectangular groove 4 a formed at the upper end of the accelerator pedal arm 4, and moves with respect to the accelerator pedal arm 4 without affecting the accelerator pedal arm 4. Therefore, even if the brake pedal 2 is operated in a state where the accelerator pedal 1 is not depressed, the accelerator pedal 1 remains stationary, and the driver does not feel uncomfortable. When the driver removes his / her foot from the brake pedal 2, the brake pedal 2 returns to the initial position shown in FIG. 2 (the position indicated by the broken line in FIG. 4) by the urging force of a return spring (not shown), and the holder lever 9 returns to the return spring 11. 2, the inner wire 7b is pulled back by returning to the initial position shown in FIG. 2 (the broken line position in FIG. 4). At this time, the inner wire 7b is formed in a rectangular groove 4a formed at the upper end of the accelerator pedal arm 4. Since the inner wire 7b does not push the accelerator pedal arm 4 by sliding inside, an excessive force is not applied to the inner wire 7b, and the durability thereof is improved.

  Also, as shown in FIG. 5, when the driver accidentally depresses the accelerator pedal 1 and the brake pedal 2 simultaneously with one foot, only the operation of the brake pedal 2 is first enabled and the vehicle is decelerated immediately. There is no delay in deceleration.

  That is, since the play a shown in FIG. 4 is formed between the connecting member 8 fixed to the end of the inner wire 7a by the depression of the brake pedal 2 and the upper end of the accelerator pedal arm 4, the play a There is play in the depression of the accelerator pedal 1 for the corresponding stroke S (stroke until the accelerator pedal arm 4 at the position of the broken line in FIG. 5 swings to the position indicated by the chain line and comes into contact with the connecting member 8). In the range of the play, the depression operation of the accelerator pedal 1 is not transmitted to the inner wire 7b (the inner wire 7b is not pulled out from the outer cable 7a), and the inner wire 7b is not pulled in on the throttle valve side. Fully closed (idle opening) is maintained and the vehicle is not accelerated.

  Then, if the accelerator pedal 1 is largely depressed beyond the play stroke S while the brake pedal 2 is depressed, the accelerator operation becomes possible. Therefore, the accelerator operation can be performed while depressing the brake pedal 2 when starting on a slope. There is no practical inconvenience. In actual hill start, if the brake pedal 2 is gradually released while the accelerator pedal 1 is depressed, the accelerator pedal 1 is not depressed further (with the accelerator pedal 1 being depressed). The pedal 1 can be further depressed.

  Further, even if the accelerator pedal 1 is depressed with the brake pedal 2 depressed, the stroke of the accelerator pedal 1 is provided with only play S shown in FIG. (It cannot be pulled out as much as when the brake pedal 1 is not depressed), and a limit is imposed on the maximum value of the engine speed.

  Furthermore, since the accelerator pedal device according to the present invention does not employ a configuration in which the depression operation of the accelerator pedal 1 is absorbed by the extension of the spring, the reaction by the spring does not return to the driver as the reaction force of the brake pedal 2, and the brake operation There is no problem that the weight becomes heavy. In particular, the brake operating force does not change depending on the depressed state of the accelerator pedal 1, and the driver does not feel uncomfortable. In the brake device of the present invention, the resultant force of the return spring (not shown) of the brake pedal 2 and the force of the return spring 11 of the holder lever 9 act as the biasing force of the brake pedal arm 6 in the return direction.

  Thus, the above effect can be obtained by a simple configuration in which the end portion on the accelerator pedal arm 4 side of the outer cable 7a is configured to be movable according to the operation of the brake pedal 2. Considering the arrangement and movement, the moving mechanism for moving the outer cable 7a can be arranged in a narrow space.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIG.

  FIG. 6 is a perspective view showing the configuration of the accelerator pedal device according to Embodiment 2 of the present invention. In this figure, the same elements as those shown in FIG. The re-explanation about is omitted.

  In the first embodiment, the holder lever 9 is configured separately from the brake pedal arm 6. However, in the present embodiment, the holder lever 6A in the first embodiment is replaced with the brake pedal arm 6 as shown in FIG. The moving mechanism of the outer cable 7a is formed by integrally forming the upper end portion above the swing shaft 5 and connecting the holder lever 6A to one end of the outer cable 7a.

  Thus, also in the accelerator pedal device according to the present embodiment, when the brake pedal 2 is depressed, the brake pedal arm 6 rotates about the swing shaft 5 in the direction of the arrow shown in FIG. A holder lever 6A formed integrally with the upper end of the cable pulls the outer cable 7a of the throttle cable 7 in the direction of the arrow in the figure. For this reason, the inner wire 7b is also pulled in the same direction, and play occurs in the depression operation of the accelerator pedal 2 as in the first embodiment (see FIG. 5). Therefore, in the present embodiment, the same effect as in the first embodiment can be obtained. However, in this embodiment, the holder lever 6A is integrated with the brake pedal arm 6, so that the number of parts is reduced and the structure is simplified. As a result, the cost can be reduced.
