Description

  The present invention relates to a pedal structure for a low floor vehicle, and more particularly to a pedal structure for a scooter type vehicle.

  As a conventional pedal structure for a low-floor vehicle, a pedal structure that includes a pedal that protrudes upward from a step floor and a footrest that is disposed behind a stepping portion of the pedal is known (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 9-52587

  By the way, in the pedal structure of the low floor vehicle described in the above-mentioned Patent Document 1, since the rotating portion of the pedal is disposed below the general surface of the substantially flat step floor, the position of the general surface of the step floor becomes high. There was a problem of ending up.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a pedal structure for a low-floor vehicle capable of lowering the position of the general surface of the step floor.

  In order to achieve the above-mentioned object, the invention according to claim 1 is provided on a step floor on which a passenger's foot is placed, a pedal rotatably supported by a vehicle body frame, and the step floor, and the pedal is upward from below. In the pedal structure of a low floor vehicle, the footrest is provided on the back surface. It has a footrest recess formed so that the portion is recessed upward, and is arranged so that at least one of a pedal support portion or a pedal rotation shaft portion that supports the pedal in a pivotable manner faces the footrest recess. .

  The invention described in claim 2 is characterized in that, in addition to the configuration of the invention described in claim 1, at least one of the pedal support portion or the pedal rotation shaft portion is disposed in the footrest recess.

  In the third aspect of the invention, in addition to the configuration of the invention of the first aspect, the step floor is substantially flat, and the axial center of the pedal rotation shaft portion is in the side view of the general surface of the step floor. The insertion part to the pedal insertion hole of a pedal arrange | positioned in the vicinity is arrange | positioned substantially orthogonally to a step floor, It is characterized by the above-mentioned.

  According to a fourth aspect of the invention, in addition to the configuration of the first aspect of the invention, the vehicle body frame includes a pair of left and right floor frames that support the step floor from below, and the pedal support portion is And a rotating shaft support portion protruding upward from one of the pair of left and right floor frames, and a rotating shaft supported by the rotating shaft support portion and protruding inward in the vehicle width direction.

  The invention according to claim 5 is characterized in that, in addition to the configuration of the invention according to any one of claims 1 to 4, a load receiving portion for receiving the load of the footrest is disposed in the recess of the footrest.

  The invention described in claim 6 is characterized in that, in addition to the configuration of the invention described in claim 5, the load receiving portion is provided in the pedal support portion.

  According to the pedal structure of the low floor vehicle according to claim 1, the pedal support portion or the pedal rotation shaft portion that rotatably supports the pedal is disposed so as to face the footrest concave portion on the back surface portion of the footrest. Therefore, the position of the general surface of the step floor can be lowered while maintaining a good clearance between the step floor and at least one of the pedal support portion or the pedal rotation shaft portion.

  According to the pedal structure of the low floor vehicle according to claim 2, since at least one of the pedal support portion or the pedal rotating shaft portion is disposed in the footrest recess, the position of the general surface of the step floor can be further lowered. .

  According to the pedal structure of the low floor vehicle according to claim 3, the step floor is substantially flat, and the shaft center of the pedal rotation shaft portion is disposed in the vicinity of the general surface of the step floor in the side view. Since the insertion part to the pedal insertion hole is arranged substantially orthogonal to the step floor, the swinging direction of the pedal insertion part can be made substantially orthogonal to the step floor at the position of the pedal insertion hole. Thereby, the pedal can be stepped on stably, and the size of the pedal insertion hole can be minimized.

  According to the pedal structure of the low floor vehicle according to claim 4, the vehicle body frame includes a pair of left and right floor frames that support the step floor from below, and the pedal support portion extends upward from one of the pair of left and right floor frames. Since the rotating shaft support portion that protrudes and the rotating shaft that is supported by the rotating shaft support portion and protrudes inward in the vehicle width direction are provided, the dimension in the vehicle width direction of the pedal support portion can be kept small. Thereby, since a footrest recessed part can be made small, the general surface of the step floor around a footrest can be enlarged.

  According to the pedal structure of the low floor vehicle according to the fifth aspect, since the load receiving portion for receiving the load of the footrest is disposed in the footrest recess, the footrest can be stably supported.

  According to the pedal structure of the low floor vehicle according to claim 6, since the load receiving portion is provided on the pedal support portion, it is not necessary to extend the load receiving portion upward from the vehicle body frame. Can be.

Thereby, the rear brake pedal 50 can be stepped on stably, and the size of the pedal insertion hole 47 can be minimized.

  Further, according to the pedal structure of the low floor vehicle of the present embodiment, the pedal support portion 60 is supported by the rotary shaft support portion 61 protruding upward from the right floor frame 14 and the rotary shaft support portion 61, and the vehicle width. Since the rotation shaft 62 that protrudes inward in the direction is provided, the dimension in the vehicle width direction of the pedal support portion 60 can be kept small. Thereby, since the footrest recessed part 48a can be made small, the general surface 49 of the step floor 44 around the footrest 48 can be widened.

  Further, according to the pedal structure of the low floor vehicle of the present embodiment, the footrest support piece 67 that receives the load of the footrest 48 is disposed in the footrest recess 48a, so that the footrest 48 can be stably supported.

  Further, according to the pedal structure of the low floor vehicle of this embodiment, since the footrest support piece 67 is provided on the pedal support portion 60, it is not necessary to extend the footrest support piece upward from the vehicle body frame. Can be made compact.

In addition, this invention is not limited to what was illustrated to the said embodiment, In the range which does not deviate from the summary of this invention, it can change suitably.
For example, in the said embodiment, although the footrest is integrally formed with the step floor, it is not limited to this, You may form separately from the step floor. In this case, if a separate footrest, a step floor, and a maintenance for maintaining a battery etc. provided separately are integrated, a derivation with a pedal on the step floor and a derivation without a pedal will be made. It is only necessary to replace the maintenance that is smaller than the step floor, and the investment such as molds can be suppressed. Moreover, it is the same when the pedal insertion hole and the footrest are integrated and separated from the step floor.
Moreover, in the said embodiment, although the pedal support part is integrally supported by the vehicle body frame, it is more preferable that it is supported by the vehicle body frame so that attachment or detachment is possible.
In the above embodiment, the pedal is described as a rear brake pedal. However, the present invention is not limited to this, and the pedal extends up from the step floor and is operated up and down, such as an accelerator pedal, a clutch pedal, and a parking operation pedal. Anything is acceptable.
