Description

  The present invention relates to a device for preventing a malfunction when an accelerator pedal of a car is accidentally depressed as a brake pedal.

  In recent years, accidents frequently occur when the driver erroneously presses the accelerator pedal as the brake pedal, and accident prevention measures are desired. Conventionally, in pedal operation, when stepping on the brake pedal, the foot (usually the right foot, the same applies hereinafter) is stretched forward as it is without twisting the foot, while when stepping on the accelerator pedal, the foot is turned clockwise. It is known to twist and put it on the accelerator pedal and to step on it. Conventionally, as a device for accident prevention measures using this knowledge, an arc-shaped hole is made in the accelerator pedal, and the tip of the operating body acting on the switch is protruded from this hole, and the operating body is a hole with the driver's foot When the switch is moved along and the switch is activated to turn on, it is judged that the accelerator operation is normal, but when the switch is not turned on despite the depression of the accelerator pedal, the accelerator operation is abnormal, There is known a configuration in which it is determined that the brake pedal is incorrectly depressed (Patent Document 1).

  Hereinafter, a first embodiment of the present invention will be described based on FIGS. 1 to 5 of the attached drawings. As shown in FIGS. 1 and 3, a detection area X1 is provided along the side opposite to the brake pedal (not shown, hereinafter the same) on the accelerator pedal body 1. The accelerator pedal body 1 shown in FIG. 2 and FIG. 3 is connected to an accelerator rod (not shown) in a conventionally known configuration. The upper and lower surfaces of the accelerator pedal main body 1 are entirely covered with the upper surface plate 2 and the lower surface plate 3, and the plates 2 and 3 are connected to each other by the bolts 4 (see FIGS. 1 and 3). It is done. A side plate 5 is fixed to the rear end side (left side in FIG. 2) of the edge opposite to the connection end of each plate 2, 3 and a portion of the side plate 5 extending downward from the lower plate 3 is , And the support shaft 6 is rotatably supported through. Therefore, the accelerator pedal main body 1 can be pivoted integrally with the plates 2 and 3 and the side plate 5 with the support shaft 6 as an axis.

  As can be understood from FIG. 3, a block-like stepping member 7 disposed in a detection area X1 along the side edge of the accelerator pedal body 1 opposite to the brake pedal is fixed to the support shaft 6. A spring 8 is wound around the support shaft 6 (see FIG. 2), and one end of the spring 8 is fixed to the step-in member 7 and the other end is fixed to the side plate 5. As a result, when the stepping-in member 7 is depressed, the stepping-in member 7 can swing around the support shaft 6 and is resiliently urged in the opposite direction. In the standby state, the upper surface of the step-in member 7 projects upward from the upper surface plate 2, and when the step-in operation is performed, the upper surface of the step-in member 7 and the upper surface of the upper surface plate 2 are coplanar. It will be located. Although the distance between the side plate 5 and the step-in member 7 is widely expressed in FIG. 3, it is sufficient in fact if there is a sufficient distance for providing the spring 8.

  As can also be seen in FIG. 3, a displacement blocking member 9 is pivotally supported on the support shaft 6 at its upper end. The displacement preventing member 9 is in the standby state in the state of FIG. 2 and has a J-shaped side surface, the upper surface is in contact with the lower surface plate 3 and the upper surface is pushed downward when the accelerator pedal body 1 is depressed. The curved lower surface in contact with the surface FL slides in the right direction in FIG. 2 to swing and displace (see FIG. 5), thereby allowing the accelerator pedal body 1 to be stepped on and displaced. A resilient biasing force by a spring (not shown) is applied to the displacement blocking member 9 in the anti-pivoting displacement direction, so that it can return to the standby state. An engagement hole 10 is provided at a position below the support shaft 6 of the displacement prevention member 9. In addition, it is suitable for the contact part with the displacement prevention member 9 lower surface of the floor surface FL to adhere a sheet material with little friction so that the said lower surface may slide smoothly.

  As shown in FIG. 3, the U-shaped regulating member 11 is connected and fixed to the step-in member 7 through the connecting member 12, and as can be understood from FIG. Plunging into and engaging with the engagement hole 10 of the displacement blocking member 9 prevents the displacement blocking member 9 from swinging. The restricting member 11 can be rocked so as to protrude into the engagement hole 10 in conjunction with the rocking operation according to the depression of the step-in member 7, and the spring 8 makes an engaging direction (a rushing direction) It is in a state of being urged. When the step-in member 7 is depressed, the restricting member 11 swings together with the step-in member 7 against the resilient biasing force of the spring 8 and the tip end portion thereof escapes from the engagement hole 10 of the displacement preventing member 9 By releasing the engaged state to allow the displacement blocking member 9 to swing, the accelerator pedal body 1 can be stepped on and displaced.

  Here, the operation of the first embodiment configured as described above will be described. In the standby state shown in FIG. 2, when the driver intends to step on the brake pedal and mistakenly steps on the accelerator pedal body 1, the driver's foot is mounted on the plate upper surface 2 in a substantially straight state so as to step on the brake pedal. Since it is placed, it does not reach the stepping member 7 provided in the detection area X1. Therefore, since the step-in member 7 is not depressed and the engagement between the restricting member 11 and the displacement preventing member 9 is not released, the displacement preventing member 9 does not swing, and the accelerator pedal main body You can not step into one. As a result, it is possible to prevent a malfunction caused by depressing the accelerator pedal accidentally with the brake pedal.

  On the other hand, when the driver intends to step on the accelerator pedal body 1, the driver's foot is placed on the plate upper surface 2 in a state of being twisted in the direction of the accelerator pedal and inclined. It will reach 7 (see FIG. 11). Then, when the stepping-in member 7 is depressed, the regulating member 11 is swung in the reverse engagement direction according to the swinging of the stepping-in member 7, and the tip end part thereof is disengaged from the engagement hole 10 to release the engagement state As a result, the displacement prevention member 9 can swing and the accelerator pedal body 1 can be stepped on. At this time, the upper surface of the step-in member 7 is flush with the upper surface of the upper surface plate 2, and the accelerator pedal body 1 is depressed together with the step-in member 7 to operate the control system of the fuel injection device and electric motor (not shown). Increase the power output of the engine and electric motor. Thus, when the engine is running, the driving is continued.

  In this state, when the stepping operation is stopped and the foot is released from the stepping member 7 and the accelerator pedal body 1 in order to reduce the output of the engine or the electric motor, the stepping member 7 returns to the standby state by the elastic force of the spring 8 and the accelerator pedal The main body 1 also returns to the standby state. At this time, the displacement preventing member 9 is also returned to the standby state by the resilient force of a spring (not shown), and the regulating member 11 comes into contact with the step-in member 7 and returns by swinging back. It is guided by the inclined surface and pushed into the engagement hole 10 to be in the engaged state shown in FIG.

  Next, a second embodiment of the present invention in which the ignition system is turned on and off to drive or stop the engine will be described based on FIGS. As shown in FIGS. 6 and 8, a detection area X2 is provided along the side surface of the accelerator pedal main body 21 opposite to the brake pedal. The accelerator pedal main body 21 shown in FIG. 7 and FIG. 8 is connected to an accelerator rod (not shown) in a conventionally known configuration as in the first embodiment. On the upper surface of the accelerator pedal body 21, an intermediate plate 22 having the same size as the accelerator pedal body 21, a mat-like second pressure sensitive switch 23, which is a second detection switch for detecting that the accelerator pedal is depressed, an upper plate 24 The lower plate 25 which is wider than the accelerator pedal body 21 and extends to the detection area X2 is arranged on the lower surface of the accelerator pedal body 21 and their contact surfaces are fixed by an adhesive. The central side plate 26 is disposed on the lower surface plate 25 at the rear end side along the side surface opposite to the brake pedal of each of the accelerator pedal body 21, the intermediate plate 22, the second pressure sensitive switch 23 and the upper surface plate 24. And the right side plate 27 is set up to face the central side plate 26 at a distance.

  As can be seen in FIGS. 6 and 8, a pivot 28 is rotatably supported on the central side plate 26 and the right side plate 27. A block-like stepping member 29 is fixed to the support shaft 28 so as to be located between the side plates 26 and 27 which is the detection area X2. Although not shown, a spring is wound around the support shaft 28 as in the first embodiment, and one end of the spring is fixed to the step-in member 29 and the other end is fixed to the central side plate 26. As a result, the step-in member 29 can be stepped on and resiliently urged in the opposite direction.

  As can be understood from FIGS. 7 and 8, on the tip end side of the stepping member 29, a first detection switch is used as a first detection switch for detecting that the stepping member 29 is depressed between the lower surface plate 25 and the first block. The pressure sensitive switch 30 is disposed, and in the standby state, the upper surface of the step-in member 29 is in the state of projecting upward from the upper surface plate 24. When the stepping-in operation is performed on the stepping-in member 29, as shown in FIG. 9, the upper surface of the stepping-in member 7 and the upper surface of the upper surface plate 25 are positioned on the same plane.

  Then, the structure which drives or stops an engine by depression detection by the above-mentioned 1st pressure sensitive switch 30 and the 2nd pressure sensitive switch 23 is demonstrated. In FIG. 10, reference numeral 31 denotes a battery, and when the first pressure sensitive switch 30 is turned on, the battery 31 is turned on from the off state. When the first relay circuit 32 and the second pressure sensitive switch 23 are turned on. It is a power supply of the 2nd relay circuit 33 which will be in an OFF state from an ON state. The outputs of the relay circuits 32 and 33 turn on and off the ignition system 34, and when the ignition system 34 is turned on and off, the engine (not shown) is driven or stopped. Since the second relay circuit 33 is in the on state in the standby state, the engine can be started by key operation.

  Here, the operation of the above-described second embodiment will be described. In the standby state, when the accelerator pedal body 21 and the stepping member 29 are depressed, the first pressure sensitive switch 30 and the second pressure sensitive switch 23 are turned on, the second relay circuit 33 is turned off, and the first relay circuit 32 is turned on. As a result, the ignition system 34 is turned on to drive the engine (not shown), and continues while driving. On the other hand, even if the accelerator pedal body 21 is depressed, if the stepping member 29 is not depressed, the second pressure sensitive switch 23 is turned on and the first pressure sensitive switch 30 is turned off. The relay circuits 33 are both off, the ignition system 34 is off, and the engine (not shown) is shut off. As a result, it is possible to prevent a malfunction caused by depressing the accelerator pedal accidentally with the brake pedal.
