[0026] In the drawings, like parts are designated by like reference numerals. The drawings are not drawn to scale. Detailed Description of the Invention
[0027] The present invention will be further described below in conjunction with the drawings.
[0028] Figure 1 Schematically shows the overall structure of a footrest device (hereinafter simply referred to as "footrest device") 1 in the driver's cab of a rail vehicle according to an embodiment of the present invention. Users (such as drivers and non-drivers) often perform many functions (hereinafter simply referred to as "main functions") such as unattended vigilance, whistling, and sanding by stepping on the footrest device. The structures associated with these functions are known in the art and will not be elaborated here.
[0029] As Figure 1 shown, the footrest device 1 includes a fixed seat 10. The fixed seat 10 includes a fixed top plate 11 and a fixed bottom plate 12 that are spaced apart from each other. Side plates and a back plate are constructed between the fixed top plate 11 and the fixed bottom plate 12 for stably connecting the fixed top plate 11 and the fixed bottom plate 12.
[0030] A footrest box 30 is provided in the fixed seat 10. As Figure 2 and Figure 3 shown, the footrest box 30 includes a box front plate 31, box side plates 32, 33, a box top plate 34, a box bottom plate 35, and a box back plate. The box front plate 31 is connected to the box side plates 32, 33, and the box bottom plate 35. The box top plate 34 is connected to the box side plates 32, 33, and the box back plate. The box front plate 31 and the box top plate 34 are both constructed as plates with relatively small lengths and are not connected to each other, thereby forming an opening with a sloping contour between them. The shapes of the box side plates 32, 33 are correspondingly constructed as trapezoids, and the sloping sides of the trapezoids correspond to the opening. The footrest box 30 is located between the fixed top plate 11 and the fixed bottom plate 12 in height.
[0031] The footrest device 1 further includes a footrest plate 20. The footrest plate 20 is disposed obliquely and covers the opening of the footrest box 30 to form a cover of the footrest box 30. The footrest plate 20 is for users to step on.
[0032] As Figure 1 shown, the connecting edge of the footrest plate 20 is hinged to the upper edge of the box front plate 31. For example, a long hinge 311 can be used to achieve the hinged connection of the entire connecting edge of the footrest plate 20 and the entire upper edge of the box front plate 31. That is, the long hinge 311 covers the entire connecting edge of the footrest plate 20 and the entire upper edge of the box front plate 31. Thus, the footrest plate 20 can be flipped relative to its connecting edge.
[0033] The footrest device 1 further includes an adjustment mechanism for adjusting the height and / or angle of the footrest 20 relative to the fixed seat 10.
[0034] As Figure 2 and Figure 3 shown, the adjustment mechanism includes an angle adjustment component. The angle adjustment component includes an angle adjuster 60 located within the footrest box 30 and extending between the box bottom plate 35 and the footrest 20. One end 61 of the angle adjuster 60 is hinged to the box bottom plate 35, and the other end 62 is hinged to the footrest 20. For example, the angle adjuster 60 can be a hydraulic cylinder or a pneumatic cylinder. In a preferred embodiment, the angle adjuster 60 is a gas spring with a lockable length.
[0035] The length of the angle adjuster 60 is adjustable. By adjusting the length of the angle adjuster 60, the footrest 20 can be flipped relative to its connecting edge, thereby adjusting the inclination angle of the footrest 20 relative to the fixed seat 10. When the angle adjuster 60 extends, the footrest 20 rotates clockwise, so that the angle between the footrest 20 and the fixed bottom plate 12 of the fixed seat becomes larger, that is, the footrest 20 inclines steeper relative to the fixed bottom plate 12 of the fixed seat 10. When the angle adjuster 60 shortens, the footrest 20 rotates counterclockwise, so that the angle between the footrest 20 and the fixed bottom plate 12 of the fixed seat becomes smaller, that is, the footrest 20 inclines more gently relative to the fixed bottom plate 12 of the fixed seat 10.
[0036] For example, the angle between the footrest 20 and the fixed bottom plate 12 can be adjusted between 15° and 25°.
[0037] As Figure 2 shown, the angle adjuster 60 is connected to the footrest 20 at a relatively centered position in the transverse direction, which is beneficial to making the force exerted by the angle adjuster 60 on the footrest 20 more balanced, and further making the adjustment process more stable.
[0038] As Figure 1 and Figure 3 shown, an angle adjustment button 22 is installed on the footrest 20. The angle adjustment button 22 is electrically connected to the angle adjuster 60. When the angle adjustment button 22 is pressed, the length of the angle adjuster 60 can be adjusted. When the angle adjustment button 22 is released (loosened), the length of the angle adjuster 60 can be locked. In addition, it can also be set that when the angle adjustment button 22 is pressed, if the force applied to the footrest 20 exceeds the first pressure threshold, then the angle adjuster 60 will shorten, otherwise the angle adjuster 60 will extend. This is beneficial to simplifying the operation of the user and facilitating the user to adjust the footrest device 1.
[0039] In addition, the angle adjustment button 22 is configured to allow the angle adjuster 60 to adjust the length only when the pressing pressure exceeds a third pressure threshold (less than the first pressure threshold). This third pressure threshold is significantly greater than the pressure required to trigger the main function by stepping on the foot pedal 20. On the one hand, this enables the user to adjust the angle of the foot pedal 20 through a simple operation of pressing the angle adjustment button 22 on the foot pedal. On the other hand, this can also effectively prevent the user from accidentally adjusting the angle of the foot pedal 20 when they hope to trigger the main function.
[0040] Furthermore, when the angle adjustment button 22 is pressed, the main function of the footrest device 1 can be locked so that the main function of the footrest device 1 is not accidentally triggered.
[0041] Alternatively, the above-mentioned angle adjustment button 22 can be connected to the angle adjuster 60 through a mechanical connection. For example, the angle adjustment button 22 can be connected to the angle adjuster 60 through a wire. When the angle adjustment button 22 is pressed, the wire pulls the angle adjuster 60, changing it from locked to adjustable.
[0042] In addition, as Figure 1 shown, the angle adjustment button 22 can be arranged at the corner of the foot pedal 20 to prevent the user from accidentally touching the angle adjustment button 22.
[0043] As Figure 2 and Figure 4 shown, the adjustment mechanism further includes a height adjustment component. The height adjustment component includes a height adjuster 50. The height adjuster 50 can be used to adjust the height of the foot pedal box 30 between the fixed top plate 11 and the fixed bottom plate 12, thereby adjusting the height of the foot pedal 20 covering the foot pedal box 30 relative to the fixed bottom plate 12.
[0044] Those skilled in the art can understand that the footrest device 1 usually has a relatively compact structure, especially in terms of height, to avoid other important structures in the cab. In this case, to ensure a larger adjustable range of the height of the foot pedal 20, the lower end of the height adjuster 50 is supported on the fixed bottom plate 12, and the upper end extends upward beyond and passes through the top plate 34 of the foot pedal box 30. This upper end can be connected to the top plate 34 of the foot pedal box 30 through a tension member 90. As Figure 2 shown, the tension member 90 can be configured as a long and narrow plate member. The upper end of the height adjuster 50 can be connected to both sides of the top plate 34 through 2 tension members 90 respectively, so as to stabilize the balance of the foot pedal box 30 while applying force.
[0045] Thus, when the height adjuster 50 extends, the height adjuster 50 pulls the footrest box 30 upward. The footrest 20 rises relative to the fixed base plate 12 together with the footrest box 30. When the height adjuster 50 shortens, the footrest 20 descends relative to the fixed base plate 12 together with the footrest box 30. This realizes the adjustment of the height of the footrest 20. For example, the height adjuster 50 can be a hydraulic cylinder or a pneumatic cylinder. In a preferred embodiment, the height adjuster 50 is a gas spring with lockable length.
[0046] As Figure 1 shown, a height adjustment button 23 is installed on the footrest 20. The height adjustment button 23 is electrically connected to the height adjuster 50. When the height adjustment button 23 is pressed, the length of the height adjuster 50 can be adjusted. When the height adjustment button 23 is released (loosened), the length of the height adjuster 50 can be locked.
[0047] In addition, it can also be set that when the height adjustment button 23 is pressed, if the force applied to the footrest 20 exceeds the second pressure threshold, then the height adjuster 50 will shorten, otherwise the height adjuster 50 will extend. This second pressure threshold is significantly greater than the pressure required to trigger the main function by stepping on the footrest 20. This is beneficial to simplify the operation of the user and facilitate the user to adjust the footrest device 1.
[0048] The angle adjustment button 22 can be configured to allow the height adjuster 50 to adjust its length only when the pressing pressure exceeds the fourth pressure threshold (less than the second pressure threshold). This fourth pressure threshold is significantly greater than the pressure required to trigger the main function by stepping on the footrest 20. On the one hand, this enables the user to adjust the height of the footrest 20 through the simple operation of pressing the height adjustment button 23 on the footrest. On the other hand, this can also effectively prevent the user from accidentally adjusting the angle of the footrest 20 when hoping to trigger the main function.
[0049] In addition, when the height adjustment button 23 is pressed, the main function of the footrest device 1 can be locked so that the main function of the footrest device 1 will not be accidentally triggered.
[0050] As an alternative, the above-mentioned height adjustment button 23 can be connected to the height adjuster 50 through a mechanical connection. For example, the height adjustment button 23 can be connected to the height adjuster 50 through a wire. When the height adjustment button 23 is pressed, the wire pulls the height adjuster 50, making it change from locked to adjustable.
[0051] In addition, as Figure 1 shown, the height adjustment button 23 can be arranged at the corner of the footrest 20 to prevent the user from accidentally touching the height adjustment button 23.
[0052] As Figures 2 to 4As shown, a guide rod 70 is provided between a fixed top plate 11 and a fixed bottom plate 12. The guide rod 70 extends vertically, with its lower end supported on the fixed bottom plate 12 and its upper end supported on the fixed top plate 11. A guide sleeve is sleeved outside the guide rod 70. The guide sleeve can be fixedly connected to the foot pedal box 30 and is supported between the box bottom plate 35 and the box top plate 34 of the foot pedal box 30. When the foot pedal box 30 moves in the height direction relative to the fixed seat 10, the guide sleeve slides correspondingly along the guide rod 70. As Figure 4 shown, the height adjuster 50 is arranged centrally in the horizontal direction, and two sets of guide rods 70 and guide sleeves are symmetrically arranged on the left and right sides of the foot pedal box 30 relative to the height adjuster 50. In this case, the structure of the foot pedal device 1 is more stable. When adjusting the height of the foot pedal box 30, the adjustment process will also be more stable.
[0053] In addition, when the height adjustment button 23 and the angle adjustment button 22 are arranged at the corners of the foot pedal 20, this symmetrical structure of the guide rod 70 and the guide sleeve can further prevent the force on the foot pedal device 1 from losing balance, thus further ensuring the structural stability of the foot pedal device 1 and the stability of the adjustment process.
[0054] In Figure 4 and Figure 5 the shown embodiment, the guide sleeve includes an upper guide sleeve part 81 and a lower guide sleeve part 82 inserted under the upper guide sleeve part 81. The upper end of the upper guide sleeve part 81 is constructed with an upper flange 811. The upper guide sleeve part 81 is fixedly connected to the box top plate 34 of the foot pedal box 30 through the upper flange 811. The lower end of the lower guide sleeve part 82 is constructed with a lower flange 821. The lower guide sleeve part 82 is fixedly connected to the box bottom plate 35 of the foot pedal box 30 through the lower flange 821. This fixing method makes the connection between the foot pedal box 30 and the guide sleeve more stable. In addition, through the design of the upper guide sleeve part 81 and the lower guide sleeve part 82, the guide sleeve can be effectively extended, and the main contact points between the guide sleeve and the guide rod 70 are formed at the upper flange 811 and the lower flange 821, and the distance between these two contact points is relatively large. In addition, lubricant can be provided in the entire long guide sleeve. Thus, the friction between the guide sleeve and the guide rod 70 can be reduced, and the wear and scratches between the guide sleeve and the guide rod 70 can be reduced. For the foot pedal device 1, due to the limitation of its use scenario, it is not convenient to perform regular maintenance on it. Therefore, the design of the upper guide sleeve part 81 and the lower guide sleeve part 82 can effectively extend the service life of the foot pedal device 1. This is very important for the foot pedal device 1.
[0055] Also as Figure 1 and Figure 2 shown, a front cover plate 14 can be added to the fixed seat 10 of the foot pedal device 1. The front cover plate can shield the guide rod 70 and the tension member 90 to prevent them from being damaged. The front cover plate 14 is detachable to inspect and maintain the guide rod 70 and the tension member 90.
[0056] A telescopic dust cover 40 can also be provided between the bottom plate 35 of the foot pedal box 30 and the fixed bottom plate 12. This dust cover 40 can prevent impurities from entering the foot pedal box 30, thereby extending the service life of the foot pedal device 1.
[0057] The foot pedal 20 can be detached to inspect and maintain the structure inside the foot pedal box 30.
[0058] Through the above-mentioned foot pedal device 1, the height adjustment and / or angle adjustment of the foot pedal 20 can be conveniently and effectively achieved. Thus, the height and / or angle of the foot pedal 20 can be adapted to the user's body size and usage habits, making the user feel more comfortable and convenient when stepping on the foot pedal 20. This can further reduce the user's fatigue and enable the user to maintain a high level of concentration and reaction ability for a longer time.
[0059] Although the present invention has been described with reference to the preferred embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way. The present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
