Description

  The present invention relates to an accelerator pedal structure for an automobile having a pedal portion that can be stepped forward by a driver's right foot.

  In general, the accelerator pedal structure for an automobile includes a suspension type shown in FIG. 10 and an organ type shown in FIG.

  The suspended pedal structure shown in FIG. 10 has a pedal arm 72 pivotally supported on a support shaft 71 at the rear of the dash lower panel, and a pedal portion 73 is integrally attached to the lower end portion of the pedal arm 72. The pedal portion 73 moves forward by a swinging locus X2 centering on the support shaft 71, whereas the toe of the occupant (driver) is a heel (so-called heel). Since the movement is downward and forward by the swing locus Y2 centering on the point), a difference is generated between the swing locus X2 of the tread surface of the pedal 73 and the swing locus Y2 of the toe.

  Further, in the hanging type pedal structure shown in FIG. 10, the tread surface of the pedal portion 73 is curved so that the tread surface and the occupant's toe are in point contact or line contact. It is configured to be slippery.

  On the other hand, the organ-type pedal structure shown in FIG. 11 is disposed on a floor surface 81 in front of the driver's seat via a pedestal 82, and a lower end portion is pivotally supported by the pedestal 82 and extends from the pivotal support portion 83 in the front upper direction. The pedal portion 84 can be stepped forward by the driver's right foot. That is, it has the pivot part 83 as a rotation fulcrum in the floor surface 81 side, It is comprised so that it may rock | fluctuate in the front-back direction substantially by setting this pivot part 83 as a pivot axis.

In this organ-type pedal structure, as shown by an imaginary line α in FIG. 11, when the heel is placed at an appropriate position close to the pivot portion 83 and the heel point and the pivot portion 83 of the pedal portion 84 are brought close to each other, In the stepping operation, the shift between the tread surface of the pedal portion 84 and the foot is eliminated. In other words, the swinging trajectory of the foot and the swinging trajectory of the tread surface of the pedal portion 84 are substantially the same, and the pedal is operated in an easy state by placing the entire foot on the tread surface of the pedal portion 84 by setting an appropriate reaction force on the pedal portion 84. In particular, it is difficult to get tired even during long distance running.
Moreover, in this organ type pedal structure, in order to put a foot | leg on the tread surface of the pedal part 84 reliably, the said tread surface is formed in the flat shape.

  However, even if the occupant is accustomed to the suspension type pedal structure, even if it is an organ type pedal structure, he / she tries to operate the pedal part 84 with the toe and places a saddle on the vehicle rear side from the pivotal support part 83 shown in FIG. There is a tendency to press the tread surface of the pedal portion 84 with a toe.

  As shown by a solid line β in FIG. 11, when the heel is placed at a position away from the pivot 83, a heel point difference ΔL is formed with respect to an appropriate heel position indicated by an imaginary line α in FIG. When the pedal portion 84 is operated with the tip of the toe, the operating force is heavy, the difference between the swinging locus X3 of the tread surface of the pedal portion 84 and the swinging locus Y3 of the foot is increased, and the tread surface of the pedal portion 84 is flat. For this reason, there is a problem that the contact area between the tread surface and the foot is large, the tread surface and the foot are difficult to slip, and the operability is poor.

  Incidentally, in recent years, the brake assist force has been set high, and the brake pedal 90 (see FIG. 12) can be operated with a small operation force. Therefore, as shown in FIG. 12, the foot is placed on the floor surface 81 (see FIG. 11) so as to operate the pedal portion 84 of the accelerator pedal 85 and the pedal portion 91 of the brake pedal 90 without moving the scissors. There is a case where the pedal portion 84 of the accelerator pedal 85 is operated at the position Z1 and the pedal portion 91 of the brake pedal 90 is operated at the position Z2.

In the above-described organ-type pedal structure, the pedal portion 84 is supported by the base 82 with the pivot portion 83 made of a flexible member. In order to ensure the strength of the pivot portion 83, the pivot portion 83 has a predetermined width. is necessary. In order to obtain this predetermined width, when the lower portion of the pedal portion 84 is bulged toward the brake pedal 90 in the vehicle width direction and the bulging portion 86 is provided, the occupant's heel common to the positions Z1 and Z2 is There is a problem that the braking operability deteriorates due to interference with the bulging portion 86 below the pedal portion 84 of the pedal 85.
Further, as will be described later, the brake pedal 90 has a pedal surface 91 located on the vehicle rear side of the pedal surface 84 of the accelerator pedal 85, as in FIG. 4 showing the embodiment of the present application. For this reason, when operating the accelerator and brakes without moving the heel, the heel can be placed on the rear side of the vehicle rather than the optimum position for the accelerator pedal so that the brake pedal on the rear side of the vehicle can be operated easily. There is sex.

  In addition, when placing a foot at the position Z3 shown in FIG. 12 and executing a heel and toe operation during sports running, placing a heel at the lower end of the pedal portion 84 of the accelerator pedal 85 increases the pedal operation. There were difficulties.

In order to solve such problems, the structures disclosed in Patent Documents 1, 2, and 3 have already been invented.
The accelerator pedal structure for an automobile disclosed in Patent Document 1 includes a horizontal part, a rising part that rises upward from the middle in the front-rear direction of the horizontal member, and a forward and upward inclination from the upper end of the rising part. And a pad portion extending from the pedal portion, and a pivot portion of the pedal portion is provided at the rear end portion of the horizontal member so as to be substantially the same as the floor surface. The position is configured to substantially match.

  However, in the conventional structure disclosed in Patent Document 1, it is necessary to form a wide concave portion in the lower part of the floor surface to allow the movement of the horizontal member when the pedal is depressed, and the formability, waterproofness, and sound insulation of the floor are required. In addition, it is not preferable in view of the above, and in addition, when it is intended to secure a high cabin in a limited vehicle height, the concave shape recessed downward is not preferable.

  In the accelerator pedal structure for automobiles disclosed in Patent Document 2, a space is provided below the pedal portion, and a floor mat is laid. It is pivotally supported on the surface.

  However, in the conventional structure disclosed in Patent Document 2, when the occupant tries to operate the pedal portion with the toe, the heel is placed at a position away from the support shaft, which is the pivot portion of the lower portion of the pedal portion, in the rear of the vehicle. Thus, it is impossible to bring the occupant's heel closer to the pivot portion of the pedal portion in the front-rear direction.

  The accelerator pedal structure for automobiles disclosed in Patent Document 3 is such that the tread surface of the pedal portion has a concave curved surface shape in a side view.

  However, in the conventional structure disclosed in Patent Document 3, there is an advantage that the occupant's foot is difficult to be displaced due to the concave curved surface shape. On the other hand, a hinge pin as a pivot part is provided at the lower part of the pedal part. Since it does not like to step on the hinge pin, it tends to move the heel away from the hinge pin toward the rear of the vehicle. As a result, it becomes impossible to bring the occupant's heel closer in the front-rear direction to the hinge pin that is the pivotal support portion of the pedal portion.

An offset portion in which the left side located on the brake pedal arrangement side is biased to the right side opposite to the brake pedal arrangement side with respect to the virtual line obtained by linearly extending the left side of the portion immediately above the brake pedal arrangement side Formed.

  According to the above configuration, since the above-described offset portion is formed, when the occupant (driver) places a heel on the floor surface of the brake pedal so as to avoid the lower portion of the pedal portion of the accelerator pedal, the heel and the pivot portion Since the position of the pedal approaches the front-rear direction, it is a preferable way to step and the swinging trajectory of the tread surface of the pedal part and the swinging trajectory of the foot are substantially the same, and the displacement between the pedal tread surface and the foot is less likely to occur. In addition, the brake pedal can be operated without moving the rod.

In other words, the passenger who performs the basic accelerator operation puts the heel on the lower part of the pedal when operating the accelerator pedal, and operates the brake pedal once by releasing the heel from the floor when depressing the brake pedal. . For passengers who perform basic accelerator operations in this way, they can place their feet on the pedal part of the accelerator pedal and operate in a comfortable position, while the passengers who are used to the hanging pedal structure (drivers) ), The swinging trajectory of the tread on the pedal and the swinging trajectory of the foot become substantially the same as the heel and the pivotal support of the pedal approach, causing a shift between the pedal tread and the foot. It is difficult to improve operability.
In short, the saddle position can be brought close to the pivotal support portion of the pedal portion, and the deviation between the tread surface and the foot when the accelerator pedal is depressed can be reduced.

  In one embodiment of the present invention, the offset portion is formed such that the left side in the vehicle width direction of the lower portion of the pedal portion is recessed to the right with respect to the left side immediately above.

  According to the above configuration, the occupant can perform the accelerator operation with the heel placed at a position closer to the vehicle width direction with respect to the pedal surface of the accelerator pedal, and can perform the brake operation without interference with the pedal surface.

  In an embodiment of the present invention, the offset portion is formed such that the left side of the brake pedal side at the lower portion of the pedal portion is bent to the right side with respect to the left side immediately above.

  According to the above configuration, the left side of the accelerator pedal is formed smoothly and looks good.

  In one embodiment of the present invention, the pedal portion has a first tread surface located in a front majority of the pedal portion, and the rear portion of the first tread surface is inclined more gently than the inclination angle of the first tread surface. An angled second tread surface is extended, and the pivotal support portion is provided at the extended lower end portion of the second tread surface.

  According to the above configuration, since the pivotal support portion is provided at the extending lower end portion of the second tread surface, the pivotal support portion and the position of the heel (so-called heel point) come to substantially coincide. In addition, a heel can be placed on the second tread surface during the heel and toe operation, and the operability of the heel and toe operation can be ensured.

  In one embodiment of the present invention, a recessed portion is formed at the boundary between the first tread surface and the second tread surface.

  According to the above configuration, the recessed portion is formed at a position in front of and above the pivot portion. When a heel is placed on the recessed portion, the heel and toe operation can be easily performed. The accelerator operation can be performed with a light force by the lever principle due to the separation distance from the entrance.

  In one embodiment of the present invention, the second tread surface is inclined downward toward the offset portion along the recessed portion.

  According to the above configuration, an occupant (driver) accustomed to the suspended pedal structure puts his heel on the side of the accelerator pedal, and when the toe is tilted toward the accelerator pedal, The lower part of the pedal part is less likely to interfere with the inclination of the second tread surface, so that the sole of the foot on the toe side is placed in a comfortable posture with a wide area while placing a heel on the floor on the side of the pedal. Can be placed on the first pedal tread.

  According to the present invention, the saddle position can be brought close to the pivotal support portion of the pedal portion, and there is an effect that it is possible to reduce the deviation between the tread surface and the foot when the accelerator pedal is depressed.

In other words, a passenger who performs a basic accelerator operation puts a heel on the lower portion of the pedal portion 23 when operating the accelerator pedal 20, and once depresses the heel from the floor 16 when the brake pedal 11 is depressed. The pedal 11 is operated. In this way, a passenger who performs a basic accelerator operation can place his / her feet on the pedal portion 23 of the accelerator pedal 20 and operate in an easy posture, while the passenger who is used to the suspended pedal structure. (Driver) makes the swinging trajectory of the tread surface of the pedal part 23 and the swinging trajectory of the foot approximately the same when the heel and the pivotal support part (see the hinge shaft part 22) of the pedal part 23 approach each other. Misalignment between the tread and the foot is less likely to occur, improving operability.
In short, the heel position can be brought close to the pivotal support portion (hinge shaft portion 22) of the pedal portion 23, and the shift between the tread surface and the foot when the accelerator pedal 20 is depressed can be reduced.

  In one embodiment of the present invention, the pedal portion 23 has a first tread surface 23A located in the front majority of the pedal portion 23, and the first tread surface 23A is located at the rear of the first tread surface 23A.

  According to this configuration, since the pivot portion (hinge shaft portion 22) is provided at the extended lower end portion 23b of the second tread surface 23B, the pivot portion (hinge shaft portion 22) and the position of the heel (so-called heel point) are located. It becomes almost coincident. In addition, a heel (see position Z3 in FIG. 6) can be placed on the second tread surface 23B during the heel and toe operation, and the operability of the heel and toe operation can be ensured.

  Furthermore, in one embodiment of the present invention, a recessed portion 23C is formed at the boundary between the first tread surface 23A and the second tread surface 23B (see FIG. 2).

  According to this configuration, the recessed portion 23C is formed at a position in front of and above the pivot portion (hinge shaft portion 22), and when a heel is placed on the recessed portion 23C, a heel and toe operation is performed. It becomes easy to perform, and the accelerator operation can be performed with a light force by the lever principle by the separation distance between the pivot portion (hinge shaft portion 22) and the recessed portion 23C.

  In the embodiment shown in FIGS. 7 to 9, the stepped portion 129 as the offset portion is formed so that the left side in the vehicle width direction of the second tread surface 123B as the lower portion of the pedal portion 123 is directly above the left side of the first tread surface 123A. A recess is formed on the right side. Further, in this embodiment, the recessed portion 123C between the first tread surface 123A and the second tread surface 123B is also recessed in a step shape, and the portion adjacent to the recessed portion 123C of the second tread surface 123B is a vehicle width direction brake. It has an inclined surface 140 inclined downward toward the pedal side, that is, the left side in FIG.

  Other configurations are the same as those of the first embodiment, and common portions are denoted by the same reference numerals, and detailed description thereof is omitted.

  When the step (129) is formed, as shown in FIGS. 7 and 8, when the occupant (driver) places a heel on the floor surface 16 so as to avoid the lower portion of the pedal portion 123 of the accelerator pedal 120, the notch portion 28 is formed. The heel is guided to the heel guide area e1 in the vicinity of the left side so that the position of the heel and the hinge shaft portion 122 as the pivotal support portion approaches the vehicle front-rear direction, ensuring a preferable stepping direction, and the pedal portion 123. The trajectory of the tread of the foot and the trajectory of the foot are substantially the same, preventing the occurrence of a deviation between the pedal tread and the foot, and the brake pedal 11 is also operated without moving the heel. It is configured to be able to.

  Further, as shown in a side view in FIG. 8, the pedal portion 123 described above has a flat first tread surface 123 </ b> A located in the front majority of the pedal portion 123, and the rear portion of the first tread surface 123 </ b> A A second tread surface 123B, which is substantially flat with a gentle inclination angle than the inclination angle of the first tread surface 123A, is extended, and the above-described hinge shaft portion 122 is provided on the extended lower end portion 123b of the second tread surface 123B. Here, the above-mentioned second tread surface 123B extends rearward from the above-mentioned second tread surface 123B at a gentle inclination angle, and the hinge shaft portion 122 is provided at the extended lower end portion 123b, thereby positioning the hinge shaft portion 122. It is configured to shift to the rear of the vehicle as much as possible.

  The recessed portion 123C between the first tread surface 123A and the second tread surface 123B described above is recessed in a step shape, and the portion adjacent to the recessed portion 123C of the second tread surface 123B is the vehicle width direction brake pedal side, that is, in FIG. By having the inclined surface 140 inclined downward toward the left side, the occupant (driver) puts a saddle on the saddle guidance area e1 provided on the floor of the accelerator pedal 120 on the brake pedal 11 side, and operates the accelerator pedal 120. When trying, the interference between the foot and the second tread surface 123B is prevented, so that the toe side of the foot can be sufficiently stably placed on the first tread surface 123A.

  As described above, the vehicle accelerator pedal structure according to the second embodiment is a vehicle accelerator pedal structure having the pedal portion 123 that can be stepped forward by the right foot of the driver. A brake pedal 14 (see FIG. 6) disposed at the foot in front of the seat is disposed on the floor surface 16 on the right side in the vehicle width direction and in front of the driver seat via a pedestal 21, and the lower end is pivotally supported by the pedestal 21. The left side of the second tread surface 123B, which is the lower portion of the pedal portion 123 in the present embodiment and is located on the brake pedal arrangement side, extends from the pivotal support portion (see the hinge shaft portion 122) at the portion immediately above it. An offset portion biased to the right side on the opposite side in the vehicle width direction with respect to the brake pedal arrangement side with respect to a virtual line (see L1 in FIG. 9) in which the left side of a certain first tread surface 123A is linearly extended. Is obtained by forming the step portion 129 of the in (7, 8, see FIG. 9).

  According to this configuration, as in the first embodiment, since the step portion 129 that is the above-described offset portion is formed, the occupant (driver) avoids the lower portion of the pedal portion 123 of the accelerator pedal 120 so that the floor surface 16 can be avoided. When the heel is placed in the heel guiding area e1, the position of the heel and the pivotal support portion (hinge shaft portion 122) approaches in the front-rear direction, which is a preferable way of stepping, and the trajectory of the tread surface of the pedal portion 123 and the trajectory of the foot Are substantially the same, and it is difficult for a shift between the pedal tread and the foot to occur, and the brake pedal 11 can be operated without moving the heel.

In one embodiment of the present invention, the stepped portion 129 that is the offset portion is formed such that the left side in the vehicle width direction of the lower portion of the pedal portion 123 is recessed to the right with respect to the left side immediately above. (See Figs. 7 and 9)
According to this embodiment, the occupant can perform the accelerator operation with the heel placed at a position closer to the vehicle width direction with respect to the pedal surface of the accelerator pedal 120, and can perform the brake operation without interference with the pedal surface.

In one embodiment of the present invention, the pedal portion 123 has a first tread surface 123A located in the front majority of the pedal portion 123, and the first tread surface 123A is located at the rear of the first tread surface 123A. The second tread surface 123B having a gentler slant angle than the tilt angle is extended, and the pivot portion (see the hinge shaft portion 122) is provided at the extended lower end of the second tread surface 123B. (See Figure 8)
According to this embodiment, since the pivotal support portion is provided at the extending lower end portion of the second tread surface 123B, the pivotal support portion and the position of the heel (so-called heel point) come to substantially coincide. In addition, a heel can be placed on the second tread surface 123B during the heel and toe operation, and the operability of the heel and toe operation can be ensured.

  Furthermore, in one embodiment of the present invention, a recessed portion 123C is formed at the boundary between the first tread surface 123A and the second tread surface 123B (see FIG. 8).

  According to this configuration, the recessed portion 123C is formed at a position in front of and above the pivot portion (hinge shaft portion 122), and when a heel is placed on the recessed portion 123C, the heel and toe operation is performed. It becomes easy to perform, and the accelerator operation can be performed with a light force on the principle of leverage by the separation distance between the pivot portion (hinge shaft portion 122) and the recessed portion 123C.

In one embodiment of the present invention, the second tread surface 123B is inclined downward toward the offset portion (see the step portion 129) along the recessed portion 123C. (See Figure 8)
According to this embodiment, an occupant (driver) accustomed to the hanging pedal structure places a heel on the side of the accelerator pedal 120 and tilts the toe toward the accelerator pedal 120, so that it is near the heel of the foot. And the lower part of the pedal portion 123 are less likely to interfere with each other by the inclination of the second tread surface 123B, so that the sole of the foot on the toe side with good operability is wide and easy, and the first pedal tread surface 123A Can be put on.
