  Incidentally, a front panel constituting a part of a vehicle body panel of the vehicle is disposed in front of the pedal box. For this reason, when a collision load is input to the front panel from the front of the vehicle at the time of a vehicle collision, particularly at the frontal collision with another vehicle or a rigid wall, the front panel is directed toward the rear of the vehicle in response to the collision load. There is a possibility that the rear side of the front lid comes into contact with the pedal box due to deformation.

  Here, in general, the pedal box is provided with valves on the front panel side that open and close according to the operation of the pedals, and pipes extending from the vehicle body side are connected to the valves via a connector. Has been. For this reason, when the front panel is deformed rearward when the vehicle collides with the front, first, the back side of the front panel comes into contact with the valves, and in some cases, the valves may be damaged. In particular, the connector is the most vulnerable part of the valves to the impact load. Therefore, when a collision load acts on the connector, the connection state between the valves and the piping may be released. In such a case, for example, when the connection state between the brake valve and the brake pipe is released, the brake required at the minimum for moving the vehicle does not operate, and the vehicle is allowed to run on its own and be in a safe place. It may be difficult to move to a location such as

  Accordingly, an object of the present invention is to provide a pedal structure capable of suppressing connector damage due to deformation of a vehicle body panel when a vehicle collides with the front.

  In order to achieve the above object, a pedal structure according to the present invention includes a pedal box having a frame body fixed to a dash panel in front of a driver's seat of a vehicle, a pedal rotatably supported with respect to the pedal box, and a frame. A valve disposed inside the body opening and changing its state in conjunction with the pedal, and a connector capable of connecting the valve and piping on the vehicle body side are provided. The pedal box has protective ribs that project forward from at least two locations of the frame that sandwich the opening. The vertical plane including the projecting tips of the two protective ribs is set in front of the vehicle relative to the position including the front end of the connector or the front end of the connector.

  In the above configuration, the front end of the connector connecting the valve and the pipe is disposed at the same position as the vertical plane including the protruding tips of the two protective ribs or on the vehicle interior side behind the vehicle. That is, when the vehicle body panel moves to the vehicle compartment side during a frontal collision of the vehicle, the vehicle body side rear surface of the vehicle body panel first comes into contact with the two protective ribs to prevent the vehicle body panel from moving. It is possible to effectively relieve the input of the impact load with respect to. Therefore, the connection state between the valve and the pipe is maintained, and the valve can be operated by operating the pedal even after the frontal collision of the vehicle.

  In addition, since the pedal box can be attached to the dash panel with the pedal and the valve attached to the pedal box in advance, it is possible to reliably improve the workability of the pedal and the valve. .

  The protective rib may be formed integrally with the frame.

  In the said structure, members, such as a volt | bolt for attaching a protection rib to a frame, are unnecessary. Therefore, the assembly work can be simplified and the number of parts can be reliably reduced.

  Moreover, since the protective rib is formed integrally with the frame of the pedal box, the rigidity strength of the protective rib itself can be improved.

  The valve may be inclined so that its top portion is positioned behind the vehicle rather than standing vertically, and the pedal box has a substantially box-shaped cover that bulges from the frame to the vehicle rear and encloses the valve. A part may be provided.

  In the above configuration, since the valve is housed inside the cover portion of the pedal box, the protruding front end of the protective rib and the rear surface on the vehicle front side of the frame body are arranged in front of the vehicle with respect to the front end of the valve. Therefore, even when the vehicle body panel moves backward toward the range of the frame body that does not have the protective ribs in the event of a frontal collision of the vehicle, the rear surface of the vehicle body panel first comes into contact with the rear surface of the frame body. Therefore, the valve can be effectively prevented from being damaged.

  Moreover, the part which protrudes ahead of a vehicle from opening of a frame is limited to the connector which connects a valve | bulb and piping. That is, since the only part to be protected by the protective rib is the connector, it is possible to minimize the protruding amount of the protective rib that protrudes forward from the rear surface of the frame body. Therefore, it is possible to reduce the weight of the pedal box and save the space of the pedal box in front of the vehicle.

  Furthermore, since the valve is arranged in a state where it does not protrude forward from the opening of the frame body, restrictions on the arrangement of parts and devices arranged in the space between the dash panel and the vehicle body panel can be relaxed. The degree of freedom in layout of these parts and devices can be increased.

  Further, the valve is housed in the cover portion with its top portion inclined to the passenger compartment side. In other words, the amount of protrusion of the cover portion from the vehicle compartment side lower end of the dash panel is minimized by inclining the compartment side of the cover portion that bulges toward the rear of the vehicle along the inclination of the side portion of the valve. Is possible. Therefore, a wide space can be secured in the floor of the driver's seat of the vehicle.

  The frame body may be provided with an upper plate portion that is inclined along the valve, and a lower plate portion that is bent from the lower end of the upper plate portion and extends downward, and the protective rib is provided on the lower plate portion of the frame body. You may make it protrude from.

  In the above configuration, the pedal box that can accommodate the valve has the upper plate portion of the frame body inclined toward the compartment along the valve. Therefore, since the space between the dash panel and the vehicle body panel is further expanded, the degree of freedom in layout of components and devices arranged in this space can be further improved.

  Moreover, since the protective rib protrudes forward from the lower plate portion extending in the vertical direction in the frame body and does not enter the vehicle compartment side, the protective rib is directed to the vehicle compartment side of the vehicle body panel that occurs in the event of a frontal collision of the vehicle. Can be effectively prevented by the protective rib. Therefore, it is possible to effectively prevent damage to the connector protruding from the opening of the frame body toward the front of the vehicle.

  The vehicle may be a cab-over type vehicle, the pedal may be a brake pedal, and the valve may be a brake valve that opens and closes according to the swing of the brake pedal.

  In the above configuration, when a cab-over type vehicle having a relatively narrow space between the vehicle body panel and the dash panel collides front, an impact load is unlikely to act on the connector, which is a connection portion between the brake valve and the pipe. Since the connection state with the piping is maintained, the brake can be sufficiently operated by operating the brake pedal even after the frontal collision. Therefore, since the brake function required at the minimum for moving the vehicle is ensured even after the frontal collision, the vehicle after the frontal collision can be driven to move to a safe place.

  The vehicle may be a cab-over type vehicle, the pedal may be a clutch pedal, and the valve may be a master cylinder whose internal volume changes according to the swing of the clutch pedal.

  As described above, the pedal structure according to the present invention is applied not only to an automatic vehicle (AT vehicle) but also to a manual vehicle (MT vehicle) including a clutch pedal and a master cylinder coupled to the clutch pedal. It is possible.

  ADVANTAGE OF THE INVENTION According to this invention, the damage of the connector which connects the valve | bulb and piping by the deformation | transformation of a vehicle body panel at the time of the front collision of a vehicle can be suppressed effectively with a simple structure.

  The master cylinder 35 inserts the rod 50 of the master cylinder 35 into the rod insertion hole 51 of the master cylinder storage portion 14 from the vehicle front side of the pedal box 9, and is formed at predetermined positions of the master cylinder storage portion 14 and the master cylinder 35, respectively. A bolt (not shown) is inserted into the bolt insertion hole (not shown), and a nut (not shown) is engaged and tightened to be fixed to the pedal box 9. In this state, the master cylinder 35 is arranged so as to be inclined so that its top portion is located on the vehicle compartment side as compared to a state in which the master cylinder 35 stands substantially vertically (see FIG. 3).

  In the present embodiment, the pedal box 9 is attached to the dash panel 4 with the brake pedal 32, the clutch pedal 33, the brake valve 34, and the master cylinder 35 being assembled to the pedal box 9 in advance. Thereafter, the connection port 41 of the brake valve 34 and the connector 39 of the brake pipe 40 are connected, and the connection port 49 of the master cylinder 35 and the connector 47 of the master cylinder pipe 48 are connected. In this state, the connection port 41 of the brake valve 34, the connector 39 of the brake pipe 40, the connection port 49 of the master cylinder 35 and the connector 47 of the master cylinder pipe 48 are in front of the opening 10 of the pedal box 9 and open. 10 is projected from the vehicle front side.

  Thus, according to the present embodiment, in the state where the brake valve 34 and the brake pipe 40 and the master cylinder 35 and the master cylinder pipe 48 are respectively connected, the connection port 41 of the brake valve 34 and the connector 39 of the brake pipe 40 are connected. The front end of each of the connection port 49 of the master cylinder 35 and the connector 47 of the master cylinder pipe 48 has a vehicle compartment side behind the vertical surface 59 including the projecting tips 58 and 58 of the two protective ribs 31 and 31. Placed in. That is, when the front lid 3 moves to the vehicle compartment side at the time of a frontal collision of the vehicle 1, the back surface of the front lid 3 on the vehicle compartment side first comes into contact with the two protective ribs 31, 31 to move the front lid 3. Therefore, the input of the impact load to the respective connecting portions of the brake valve 34 and the brake pipe 40 and the master cylinder 35 and the master cylinder pipe 48 can be effectively reduced. Therefore, the connection state between the brake valve 34 and the brake pipe 40 and the connection state between the master cylinder 35 and the master cylinder pipe 48 are maintained, respectively, and the brake pedal 32 and the clutch pedal 33 are maintained even after a frontal collision of the vehicle 1. Thus, the brake valve 34 and the master cylinder 35 can be operated respectively.

  Further, since the pedal box 9 can be attached to the dash panel 4 with the brake pedal 32, the clutch pedal 33, the brake valve 34, and the master cylinder 35 attached in advance to the pedal box 9, the brake pedal 32, the assembly workability of the clutch pedal 33, the brake valve 34, and the master cylinder 35 can be reliably improved.

  Since the protective rib 31 is formed integrally with the frame 12 of the pedal box 9, it is possible to simplify the assembly work and reduce the number of parts, and to increase the rigidity of the protective rib 31 itself. Can be improved.

  In addition, since the brake valve main body 38 of the brake pedal 32 and the master cylinder main body 46 of the clutch pedal 33 are housed inside the cover portion 11 of the pedal box 9, the protruding front end 58 of the protective rib 31 and the front of the frame 12 in the vehicle The rear surface on the side is disposed in front of the vehicle with respect to the front ends of the brake valve main body 38 and the master cylinder main body 46. Therefore, even when the front lid 3 moves rearward toward the range of the frame body 12 that does not have the protective ribs 31 in the event of a frontal collision of the vehicle 1, the back surface of the front lid 3 first contacts the back surface of the frame body 12. Thereby, since the movement of the front lid 3 is prevented, damage to the brake valve main body 38 and the master cylinder main body 46 can be effectively suppressed.

  The portion of the pedal box 9 that protrudes forward from the opening 10 has a connection port 41 and a connector 39 that connect the brake valve 34 and the brake pipe 40, and a connection port 49 that connects the master cylinder 35 and the master cylinder pipe 48. And the connector 47. That is, since the only parts to be protected by the protective rib 31 are the connection port 41, the connector 39, the connection port 49, and the connector 47, the protruding amount of the protective rib 31 that protrudes forward from the rear surface of the frame 12 to the vehicle front is minimized. It becomes possible to suppress to. Therefore, it is possible to reduce the weight of the pedal box 9 and save the space of the pedal box 9 in front of the vehicle.

  Further, since the brake valve main body 38 and the master cylinder main body 46 are arranged in a state where they do not protrude forward from the opening 10 of the pedal box 9, they are arranged in a relatively narrow space between the dash panel 4 and the front lid 3. It is possible to relax restrictions on the arrangement of components and devices, and to increase the degree of freedom in layout of these components and devices.

  Furthermore, the brake valve main body 38 and the master cylinder main body 46 are accommodated in the cover portion 11 with the tops thereof being inclined toward the passenger compartment. That is, the vehicle compartment side of the cover portion 11 that bulges toward the rear of the vehicle is inclined along the side portions of the brake valve main body 38 and the master cylinder main body 46, thereby covering the dash panel 4 from the vehicle compartment side lower end. It is possible to minimize the protruding amount of the portion 11. Therefore, a wide space can be secured in the floor portion of the driver's seat of the vehicle 1.

  In the pedal box 9 that can accommodate the brake valve main body 38 and the master cylinder main body 46, the upper plate portion 27 of the frame 12 is inclined along the brake valve main body 38 and the master cylinder main body 46 toward the vehicle compartment. Therefore, since the space between the dash panel 4 and the front lid 3 is further expanded, the degree of freedom in layout of components and devices arranged in this space can be further improved.

  In addition, the protective rib 31 protrudes from the lower plate portion 26 extending in the vertical direction in the frame body 12 to the front side of the vehicle and is not provided so as to enter the passenger compartment side. Can be effectively prevented by the protection rib 31. Therefore, damage to the connection port 41 of the brake valve 34, the connector 39 of the brake pipe 40, the connection port 49 of the master cylinder 35, and the connector 47 of the master cylinder pipe 48 protruding from the opening 10 of the pedal box 9 toward the front of the vehicle. It can be effectively suppressed.

  When a vehicle 1 having a relatively narrow space between the front lid 3 and the dash panel 4 collides with the front, an impact load is unlikely to act on the connection port 41 and the connector 39, which are the connecting portions of the brake valve 34 and the brake pipe 40, Since the connection state of the brake valve 34 and the brake pipe 40 is maintained, the brake can be sufficiently operated by operating the brake pedal 34 even after a frontal collision. Therefore, since the brake function required at the minimum for moving the vehicle 1 is ensured even after the frontal collision, the vehicle 1 after the frontal collision can be made to travel and move to a safe place.

  In the present embodiment, the brake pedal 32, the clutch pedal 33, the brake valve 34, and the master cylinder 35 are arranged in the pedal box 9, but for example, as shown in FIGS. It is also possible to arrange only the brake pedal 32 and the brake valve 34 without arranging the master cylinder 35. That is, the pedal structure 5 according to the present invention is not limited to being applied to a manual vehicle (MT vehicle), but can be applied to an automatic vehicle (AT vehicle). It becomes possible.

  The vehicle to which the pedal structure 5 according to the present invention can be applied is not limited to a cab overtrack type vehicle, but can be applied to a vehicle such as a passenger car.

  Further, although the brake valve main body 38 and the master cylinder main body 46 are provided at positions where they do not protrude forward from the opening 10 of the pedal box 9, the vertical surface 59 including the protruding tips 58, 58 of the two protective ribs 31, 31 is provided. Alternatively, it may protrude from the opening 10 of the pedal box 9 toward the front side of the vehicle within a range that does not protrude further toward the front of the vehicle.

  Moreover, although the protrusion amount of the two protection ribs 31 and 31 from the back surface of the frame 12 was set to the substantially same protrusion amount, it can also be set to a different protrusion amount.

  Furthermore, although two protective ribs 31 are provided on the back surface of the frame 12, two or more protective ribs 31 may be provided.

  As mentioned above, although the embodiment to which the invention made by the present inventor is applied has been described, the present invention is not limited by the discussion and the drawings that form part of the disclosure of the present invention according to this embodiment.
