Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an accelerator pedal in a vehicle.

[Prior Art] Generally, the accelerator of an automobile is operated using a foot pedal. Conventionally, this foot pedal
An arm is rotatably supported on a bracket fixed to the vehicle's dash panel, a wire connecting to the accelerator is connected to the upper end of the arm, a pedal pad is attached to the lower end, and the pedal pad is operated by the operator. When you push it with your foot, the wire is pulled and the engine throttle opening changes.

By the way, since the heights of pilots vary from person to person, they may not be able to reach the pedal pads with their feet.In such cases, the seat can be adjusted by sliding it forward. Also, if you are taller than the standard, you will have to slide the seat backwards. If the seat is slid backwards, the leg space for the person sitting in the rear seat becomes narrower, making the seat uncomfortable. Furthermore, when the seat is slid in this manner, the viewing point of the pilot naturally changes, so the viewing point will vary depending on individual differences in height. In the same vehicle, it is inherently undesirable for the viewing point to change every time the driver changes, as this changes the viewing angle and causes a difference in the width and narrowness of the field of view.

Therefore, there are known configurations in which the pedals can be adjusted back and forth in order to change the position of the pedals without sliding the seat (for example, Japanese Patent Publications No. 50-6694, No. 50-34814, and other U.S. (See Patent No. 3151499, Patent No. 3563111, etc.)

[Problems to be solved by the invention] However, according to the above-mentioned conventional example, the structure tends to be complicated, leading to high costs, and
Although there are problems with maintenance and there are simple configurations, it is questionable whether or not safety can be ensured sufficiently in actual use, regardless of theory, and thus, actual use is possible. It can be said that it has not yet been completed.

However, in this day and age of advanced automobiles, it can no longer be said that it is desirable to operate the pedals by adjusting individual differences in height by sliding the seat, due to the above-mentioned circumstances.

Therefore, in view of the above-mentioned circumstances, this invention was made for the purpose of providing an accelerator pedal that can be practically used and is adjustable back and forth.

[Means for solving the problem] In order to solve the above problem, this invention has a guide rail provided on a bracket fixed to the vehicle body,
A slider that is slidably engaged with the guide rail, a slide block that is integrally provided with the slider, a pedal arm rotatably supported by the slide block, and the slide block that is rotatably supported by the slide block. A first stay integrally protruding from the pedal arm and a drive means for moving the slider along the guide rail are provided, and a loop-shaped stay is provided between the upper end of the pedal arm and the first stay. An accelerator pedal is constructed by interposing a tube bent in the same manner as shown in FIG.

[Function] According to the above structure of this invention, when the drive means is operated so that the position of the pedal pad is appropriately arranged for each operator who has different heights, the slider is adjusted to move back and forth along the guide rail. In addition, the pedal pad and the pedal arm supporting it can be moved in parallel so that the position of the pedal pad is always maintained at a constant height.
Even if the movement of the pedal arm is adjusted, the length of the operating cable inserted through the tube interposed between the pedal arm and the first stay remains unchanged, and the length of the operating cable that is pulled depends on the angle at which the pedal is depressed. Always proportional.

[Example] Next, an example of this invention will be described based on the drawings. As shown in FIGS. 1 and 2, guide rails 2, 2 of a predetermined length are fixed oppositely to the inner wall of the bracket 1 fixed to the vehicle body, and the guide rails 2, 2 are fixed to the guide rails 2, 2, respectively. A slide block 4 with fitted sliders 3, 3 formed in a protruding manner is provided, and a screw bolt 5 for moving the slide block 4 in the front-rear direction (left and right in the drawing) is fixed to the front end of the bracket 1, as will be described later. 7 and is rotatably supported by a connecting member 2b that connects the rear ends of the guide rails 2,2. A nut 6 is attached to the slide block 4 and is screwed into a screw bolt 5. The driving means 7 is fixed to the connecting member 2a that connects the front end of the bracket 1, and the screw bolt 5 is connected to the screw bolt 5 by the driving means 7 so as to be rotatable in forward and reverse directions. The drive means 7 is an electric motor that is started to rotate in forward and reverse directions via a switch operated by a passenger. In addition, a pedal arm 8 is rotatably supported on the slide block 4 by a shaft 9.
The spring 10 is returned to the original position, and one end of the spring 10 is wound around the pedal arm 8, and the other end is applied to the slide block 4, thereby urging the pedal arm 8 to rotate in the counterclockwise direction in the figure. A yoke 11 is formed at the upper end of the pedal arm 8 and is engaged with an operating cable 12 made of a wire.The operating cable 12 passes through a flexible tube 13 of a predetermined length and is integrally attached to the slide block 4. The ball end 17 is fixed to the end portion of the ball end 17 through a through hole 15 formed in the first stay 14 that protrudes from the connecting member 2b, and through a through hole in the second stay 16 that protrudes from the connecting member 2b. ing. The tube 13 has its ends abutting the yoke 11 of the pedal arm 8 and the first stay 14, and is interposed only between them, and
A predetermined length is looped and bent. The slide block 4 is provided with a rotation stopper 18 for the pedal arm 8. pedal arm 8
A pedal pad 19 is attached to the lower end of the pedal.

Next, the operation of the above embodiment will be explained. To adjust the position of the pedal arm 8 by moving it back and forth, operate the switch of the drive means 7 to start the forward rotation, the screw bolt 5 will rotate around its axis, and the nut 6 screwed into the screw bolt 5 will rotate. The slide block 4 is moved backward along the guide rails 2, 2 via the sliders 3, 3 (to the right in Fig. 1).
The screw bolt 5 moves in parallel from the vicinity of one end of the screw bolt 5 to the vicinity of the other end, as shown by the imaginary line in FIG. This movement causes the first stay 1
The distance between the yoke 11 at the upper end of the pedal arm 8 and the first stay 14 can be changed to accommodate movement of the pedal arm.
Since the end of the tube 13 is always in contact with the yoke 11 and the first stay 14 even if the pedal arm 8 moves, the yoke 11 and the first
The length of the operating cable 12 between the stays 14 is kept constant. Therefore, when you put your foot on the pedal pad 19 and step on it, the tube 13 is caught between the yoke 11 at the upper end of the pedal arm 8 and the first stay 14 and cannot be moved. By rotating clockwise around , the tube 13 connects the yoke 11 and the first stay 1.
4 while keeping the length of the operating cable 12 constant, the operating cable 12 is pulled to the right in the figure and the throttle opening degree is changed. Thus, regardless of the position of the pedal arm 8 with respect to the slide block 4, the length of the tube 13 and the length of the operating cable 12 passing through it are constant, so that the pedal depression angle and the engine throttle opening are constant. The degree is proportional to any position of the pedal arm 8.

[Effects of the invention] According to the invention explained above, a guide rail provided on a bracket fixed to the vehicle body, a slider provided slidably in engagement with this guide rail, and an integral part of the slider are provided. a slide block provided on the slide block, a pedal arm rotatably supported by the slide block, a first stay integrally projecting from the slide block, and a pedal arm that moves the slider along a guide rail. A tube bent into a loop is interposed between the upper end of the pedal arm and the first stay, and an operating cable is inserted through the tube so that the end thereof is connected to the guide. Since the accelerator pedal is fixed to a second stay that protrudes from the rail, the pedal can be moved and adjusted to an appropriate position according to the height of the occupant, so it can be adjusted to the appropriate position regardless of individual height differences. You can drive safely and comfortably. Even if you adjust the pedal to move back and forth, the length that the pedal is depressed and the operating cable is pulled is
Since it is always held constant by the tube, no matter what position the pedal is in, it can be maintained in proportion to the angle at which the pedal is depressed. In addition, by interposing a tube bent into a loop shape between the upper end of the pedal arm and the first stay, the tube can be easily bent, so the pedal arm can be rotated smoothly without increasing the pedaling force. This provides effects such as being able to pull the operating cable by moving the cable.
