Description

Technical Field

[0001] This utility model relates to the field of locomotive structure, and in particular to an adjustable-angle foot pedal device. Background Technology

[0002] The locomotive cab is equipped with foot pedals. The driver needs to use both feet to press various mechanisms (foot switches) on the foot pedals to send signals to the locomotive. For ergonomic reasons, the foot pedals are angled. Traditional foot pedals are fixed, meaning their angle cannot be changed. This structure has certain limitations, only suitable for drivers of certain heights. For taller or shorter drivers, it is very inconvenient to use, causing comfort issues. This leads to the driver working in an uncomfortable posture for a long time, which is detrimental to the driver's health and also poses certain safety hazards.

[0003] Therefore, a method or apparatus is needed to solve the above problems. Utility Model Content

[0006] A support plate 5 is connected to the bottom surface of the foot pedal 2. A longitudinally distributed pressure rod seat 6 is provided on the support plate 5. A pressure rod 7 is movably connected within the pressure rod seat 6. The unlocking switch 3 is located at the top of the pressure rod 7. A spring 8 is sleeved on the pressure rod 7, located between the foot pedal 2 and the unlocking switch 3. The bottom end of the pressure rod 7 is hinged to two first swing rods 9. The other end of each first swing rod 9 is rotatably connected to the end of a locking rod 10. The locking rod 10 is movably connected within a locking rod seat 11. The locking rod seat 11 is horizontally distributed and fixedly connected to the support plate 5.

[0007] The side plate 1 has n locking holes 16 distributed at equal central angles. The locking holes 16 match the locking rod 10. On the inner wall of the side plate 1, a dividing steel plate 18 is rotatably connected by a spring hinge 17. The dividing steel plate 18 is provided with n limiting grooves, each of which corresponds one-to-one with one of the n locking holes 16, and the edges of the limiting grooves are smoothly transitioned.

[0008] A spring push rod 19 is provided on the inner wall of the side plate 1. One end of the spring push rod 19 is hinged to the side plate 1, and the other end is rotatably connected to the foot pedal 2.

[0009] A trigger block 12 is provided on the locking rod 10, and a pawl matching the trigger block 12 is provided on the support plate 5.

[0018] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. Figures 1 to 5 As shown: An adjustable foot pedal device, 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.

[0019] A support plate 5 is connected to the bottom surface of the foot pedal 2. A longitudinally distributed pressure rod seat 6 is provided on the support plate 5. A pressure rod 7 is movably connected within the pressure rod seat 6. The unlocking switch 3 is located at the top of the pressure rod 7. A spring 8 is sleeved on the pressure rod 7, located between the foot pedal 2 and the unlocking switch 3. The bottom end of the pressure rod 7 is hinged to two first swing rods 9. The other end of each first swing rod 9 is rotatably connected to the end of a locking rod 10. The locking rod 10 is movably connected within a locking rod seat 11. The locking rod seat 11 is horizontally distributed and fixedly connected to the support plate 5.

[0020] The side plate 1 has n locking holes 16 distributed at equal central angles. The locking holes 16 match the locking rod 10. On the inner wall of the side plate 1, a dividing steel plate 18 is rotatably connected by a spring hinge 17. The dividing steel plate 18 is provided with n limiting grooves, each of which corresponds one-to-one with one of the n locking holes 16, and the edges of the limiting grooves are smoothly transitioned.

[0021] A spring push rod 19 is provided on the inner wall of the side plate 1. One end of the spring push rod 19 is hinged to the side plate 1, and the other end is rotatably connected to the foot pedal 2.

[0022] A trigger block 12 is provided on the locking rod 10, and a pawl matching the trigger block 12 is provided on the support plate 5. The pawl includes a pawl housing 13 fixedly connected to the support plate 5. A second rocker arm 14 is rotatably connected to the pawl housing 13 via a rotating shaft. A roller 15 interfering with the movement trajectory of the trigger block 12 is provided at the bottom end of the second rocker arm 14. The second rocker arm 14 is inclined, and a torsion spring is provided at the hinge axis of the second rocker arm 14.

[0023] The first rocker arm 9 is composed of a first threaded rod 20 and a second threaded rod 21, and the first threaded rod 20 and the second threaded rod 21 are connected to each other by a threaded sleeve 22.

[0024] The working process of the adjustable angle foot pedal device in this embodiment of the utility model is as follows: In the initial state, under the action of the spring 8, the pressure rod 7 is pushed upward, and the bottom end of the pressure rod 7 is at the same height as the locking rod 10. At this time, the end of the locking rod 10 extends out and is inserted into a certain locking hole 16 (two locking rods 10 are inserted into a pair of locking holes 16 at the same time). Under the action of the locking rod 10, the foot pedal 2 and the side plate 1 are relatively fixed. The user can issue commands to the locomotive by stepping on the foot switch 4.

[0025] When it is necessary to adjust the relative angle between the foot pedal 2 and the horizontal plane, the user presses the unlock switch 3, the pressure rod 7 moves downward, the spring 8 is compressed, and the bottom end of the pressure rod 7 will drive the two first swing rods 9 to swing. When the first swing rod 9 swings in space, it will pull the locking rod 10 to move. Under the guidance of the locking rod seat 11, the locking rod 10 can only move in the horizontal direction, and finally achieves the purpose of retracting the locking rod 10 and letting its end be pulled out from the locking hole 16.

[0026] After the foot pedal 2 regains its freedom, the user can continue to apply pressure to it, causing it to swing downwards, and after adjusting to a suitable angle, extend the locking lever 10 again to lock it at a suitable tilt angle; or the user can stop applying pressure to the foot pedal 2, and under the action of the spring push rod 19, the foot pedal 2 will swing upwards, and after adjusting to a suitable angle, extend the locking lever 10 again to lock it at a suitable tilt angle.

[0027] During the movement of the locking lever 10, the trigger block 12 on it will contact the roller 15 set in the segmentation device. Since the second swing arm 14 connected to the rear end of the roller 15 is inclined, it swings and moves with the second swing arm 14 under the action of the trigger block 12. The trigger block 12 passes through. After the trigger block 12 passes the roller 15, the second swing arm 14 returns to the initial tilt angle under the action of the torsion spring. In this state, the trigger block 12 can no longer drive the roller 15 to move. That is, when the roller 15 (that is, the locking lever 10) is retracted, it cannot be extended again under the action of the segmentation device. The segmentation device can keep both locking levers 10 in the unlocked state.

[0028] This structure allows the operator to adjust the angle of the foot pedal 2 without stepping on the unlock switch 3. If downward adjustment is needed, simply step down on the foot pedal 2 with a force greater than that of the spring push rod 19. If upward adjustment is needed, no operation is required.

[0029] During the above adjustment process, under the action of the spring hinge 17, the dividing steel plate 18 will always press against the locking rod 10 (the installation position of the dividing steel plate 18 ensures that the dividing steel plate 18 will be in contact with the locking rod 10 regardless of whether the locking rod 10 is in the extended or retracted state). When the locking rod 10 moves relative to the dividing steel plate 18 with the movement of the foot pedal 2, when the locking rod 10 enters a certain limit groove, on the one hand, it will make a sound due to the collision, and on the other hand, the user can also feel the slight vibration feedback generated when the two collide, thereby helping the user to judge which tilt position the foot pedal 2 is currently in.

[0030] When it is necessary to relock the foot pedal 2 to the side plate 1, the user needs to press the unlock switch 3 to the bottom and then remove the foot. Under the action of the spring 8, the locking rod 10 moves outward. The trigger block 12 connected to the locking rod 10 will quickly hit the roller 15 and use this impact force to drive the second swing arm 14 to swing upward, so that the trigger block 12 can pass through the roller 15, ensuring that the locking rod 10 can be extended again and inserted into a corresponding locking hole 16.

[0031] In practical work, in order to facilitate installation and to make it easier to adjust the extension length of the locking rod 10 in the locked state, the first rocker arm 9 is designed to be adjustable in length. When adjustment is needed, it is only necessary to drive the first threaded rod 20 or the second threaded rod 21 to rotate relative to the threaded sleeve 22.
