A foot pedal device with customizable height for rail transit vehicles Technical Field

[0001] This utility model relates to the field of rail transit locomotives, and in particular to a foot pedal device with a customizable height for rail transit locomotives. Background Technology

[0002] The locomotive's cab is equipped with foot pedals, which the driver uses to signal the locomotive by pressing various mechanisms (such as foot switches) on the pedals. For ergonomic reasons, the foot pedals are angled.

[0003] Traditional foot pedals are fixed, meaning their tilt angle cannot be changed. This structure has certain limitations and is only suitable for drivers of certain heights. For drivers who are taller or shorter, it is very inconvenient to use, resulting in relatively poor comfort. It also forces drivers to work in an uncomfortable posture for extended periods, which is detrimental to their health and poses certain safety hazards.

[0004] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention

[0005] The present invention addresses the aforementioned shortcomings of the existing technology by proposing a foot pedal device with a simple structure, ingenious design, reasonable layout, and customizable height adjustment as needed.

[0006] The technical solution of this utility model is: a foot pedal device with a customizable height for rail transit locomotives, characterized in that: the foot pedal device includes two symmetrically distributed side plates 1, one end of each side plate 1 is rotatably connected to a foot pedal 2 via a pivot, and the foot pedal 2 is provided with an unlocking switch 3 and two symmetrically distributed foot switches 4.

[0007] The unlocking switch 3 is located at the top of the first pressure rod 5, and a return spring 6 is sleeved on the outside of the first pressure rod 5. The return spring 6 is located between the unlocking switch 3 and the foot pedal 2. The bottom end of the first pressure rod 5 is connected to the top of the second pressure rod 8 through a connector 7. The first pressure rod 5 and the second pressure rod 8 are slidably connected in a pressure rod seat 9, and the pressure rod seat 9 is fixedly connected to the foot pedal 2 through a connecting bracket 10.

[0008] The bottom end of the second pressure rod 8 is hinged to both swing rods 11, while the other end of the swing rod 11 is rotatably connected to the end of the locking rod 12. The locking rod 12 is movably connected within the locking rod seat 13, which is horizontally distributed and fixedly connected to the connecting frame 10.

[0009] The side plate 1 has n locking holes 14 distributed at equal central angles. The locking holes 14 match the ends of the locking rods 12. An arc-shaped positioning plate 15 is provided on the inner wall of the side plate 1. The arc-shaped positioning plate 15 has n positioning grooves 16, and adjacent positioning grooves 16 are smoothly transitioned. A positioning mechanism matching the arc-shaped positioning plate 15 is provided on the bottom surface of the foot pedal 2. The n positioning grooves 16 correspond one-to-one with the n locking holes 14.

[0010] The positioning mechanism includes a housing 18 fixedly connected to the foot pedal 2 by bolts 17. A push rod 19 is movably connected inside the housing 18.

[0020] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. As shown in Figures 1 to 4: A foot pedal device with a customizable height for rail transit vehicles includes two symmetrically distributed side plates 1. One end of each side plate 1 is rotatably connected to a foot pedal 2 via a pivot. The foot pedal 2 is equipped with an unlocking switch 3 and two symmetrically distributed foot switches 4.

[0021] The unlocking switch 3 is located at the top of the first pressure rod 5, and a return spring 6 is sleeved on the outside of the first pressure rod 5. The return spring 6 is located between the unlocking switch 3 and the foot pedal 2. The bottom end of the first pressure rod 5 is connected to the top of the second pressure rod 8 through a connector 7. The first pressure rod 5 and the second pressure rod 8 are slidably connected in a pressure rod seat 9, and the pressure rod seat 9 is fixedly connected to the foot pedal 2 through a connecting bracket 10.

[0022] The bottom end of the second pressure rod 8 is hinged to both swing rods 11, while the other end of the swing rod 11 is rotatably connected to the end of the locking rod 12. The locking rod 12 is movably connected within the locking rod seat 13, which is horizontally distributed and fixedly connected to the connecting frame 10.

[0023] The side plate 1 has n locking holes 14 distributed at equal central angles. The locking holes 14 match the ends of the locking rods 12. An arc-shaped positioning plate 15 is provided on the inner wall of the side plate 1. The arc-shaped positioning plate 15 has n positioning grooves 16, and adjacent positioning grooves 16 are smoothly transitioned. A positioning mechanism matching the arc-shaped positioning plate 15 is provided on the bottom surface of the foot pedal 2. The n positioning grooves 16 correspond one-to-one with the n locking holes 14.

[0024] The positioning mechanism includes a housing 18 fixedly connected to the foot pedal 2 by bolts 17. A push rod 19 is movably connected inside the housing 18. The outer end of the push rod 19 is provided with a roller 20 that matches the positioning groove 16. A spring is also provided inside the housing 18 to press the push rod 19.

[0025] A spring push rod 21 is also provided on the inner wall of the side plate 1. One end of the spring push rod 21 is hinged to the inner wall of the side plate 1, and the other end is rotatably connected to the bottom end face of the foot pedal 2.

[0026] An L-shaped support frame 22 is also provided on the inner wall of the side plate 1. An assist spring 23 is provided on the horizontal part of the L-shaped support frame 22. An assist block 24 is provided on the top of the assist spring 23. The assist block 24 can contact the bottom surface of the foot pedal 2.

[0027] The working process of the custom height foot pedal device for rail transit locomotives in this embodiment of the utility model is as follows: When it is necessary to adjust the tilt angle of the foot pedal 2, the user steps on the unlocking switch 3, which drives the first pressure rod 5 to move downward (the return spring 6 is compressed). Since the first pressure rod 5 is connected to the second pressure rod 8 through the connector 7, the above action will drive the second pressure rod 8 to move downward. When the second pressure rod 8 moves downward, it will drive the two swing rods 11 to swing. When the swing rod 11 swings, it will pull the locking rod 12 that is hinged to it to move. Since the locking rod 12 is slidably connected in the locking rod seat 13, under the guidance of the locking rod seat 13, the locking rod 12 will move horizontally. When the second pressure rod 8 is pressed down, both locking rods 12 will retract and their ends will be pulled out from the locking hole 14 on the side plate 1. At this time, the foot pedal 2 is unlocked from the side plate 1, that is, the foot pedal 2 can swing relative to the side plate 1.

[0028] During the swing of the foot pedal 2, the positioning mechanism connected to it will move along with it (relative to the side plate 1). During the movement, the roller 20 in the positioning mechanism will roll between different positioning slots 16 (since the adjacent positioning slots 16 are smoothly transitioned, the above movement can be achieved). When the roller 20 enters a certain positioning slot 16, the spring located in the housing 18 will press it tightly in the positioning slot 16. In this way, the operator will feel obvious resistance every time the roller 20 leaves the current positioning slot 16. After the roller 20 enters the next positioning slot 16, the push-out action of the push rod 19 will make the operator feel obvious vibration. In this way, the operator can determine which gear the foot pedal 2 is currently in.

[0029] When the foot pedal 2 needs to swing downward, the operator steps on the unlock switch 3 and applies downward force, driving the foot pedal 2 to swing downward as a whole. Conversely, if the operator only steps on the unlock switch 3 but does not apply too much force to the foot pedal 2, the spring push rod 21 will automatically push the foot pedal 2 to swing upward.

[0030] After the foot pedal 2 is adjusted to a suitable angle, the unlock switch 3 is released. Under the action of the reset spring 6, the unlock switch 3 returns to the initial position. The above action is reversed, and the two locking rods 12 extend outward again and are inserted into the current locking hole 14. The foot pedal 2 is locked to the side plate 1 again, and the operator can step on the foot switch 4 in a comfortable posture to issue various commands.

[0031] When the angle between the foot pedal 2 and the horizontal plane is adjusted to the minimum, the angle between the spring push rod 21, which drives the foot pedal 2 to rebound, and the horizontal plane is also very small. Therefore, there may be a situation where the foot pedal 2 cannot be pushed to swing in the opposite direction. In order to avoid the above situation, an assist block 24 is provided on the inner wall of the side plate 1 using an L-shaped support frame 22. When the foot pedal 2 is at the minimum angle, the downward assist block 24 and the assist spring 23 are compressed. When the foot pedal 2 is in the unlocked state, the assist spring 23 and the assist block 24 will push the foot pedal 2 to swing upward in the opposite direction. When the foot pedal 2 swings to a certain angle, the spring push rod 21 continues to push the foot pedal 2 to swing upward, thereby ensuring that the foot pedal 2 can return.
