Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, specifically to an adjustable lifting foot pedal device for trains. Background Technology

[0002] Currently, most train driver's cab foot pedals are designed at a fixed height, making them unadjustable to accommodate different operator body types. Since there are significant differences in lower limb length and sitting angle among operators of different genders and heights (e.g., men and women), fixed foot pedals can easily lead to problems such as feet dangling, insufficient leg support, or excessive knee flexion in some individuals (especially shorter female operators). Over long-term operation, this design flaw can easily cause muscle fatigue, joint strain, and compensatory posture, reducing driving comfort and reaction efficiency. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect that the foot pedals in the prior art cannot be adjusted, thereby providing a train adjustable lifting foot pedal device that improves operational safety and universality.

[0004] Therefore, this utility model provides an adjustable lifting foot pedal device for trains, including a foot pedal and an adjustment mechanism. The foot pedal is hinged to a base plate. The adjustment mechanism, located between the foot pedal and the base plate, includes a motor drive assembly and a lifting assembly driven by the motor drive assembly to drive the foot pedal to rotate relative to the base plate. The motor drive assembly includes a motor, a lead screw, a slide rail, a first slider, and a second slider disposed in the middle of the base plate. The lead screw is driven by the motor and is arranged vertically parallel to the slide rail. Both the first slider and the second slider are slidably connected to the slide rail, and the first slider is driven by the lead screw. The lifting assembly includes a first connecting bracket, two first support rods, a second connecting bracket, and two second support rods. The first connecting bracket is fixed to the first slider. The two first support rods are installed on both sides of the first connecting bracket, with their ends connected to the middle of the first connecting bracket and the foot pedal, respectively. The second connecting bracket is fixed to the second slider, and its two ends extend to both ends of the base plate. The two second support rods are installed on both sides of the second connecting bracket, with their two ends connected to the first connecting bracket and the foot pedal, respectively. The first support rods and the second support rods are arranged crosswise.

[0005] The second connecting bracket has rubber wheels installed at both ends that contact the base plate.

[0006] The motor is provided with support and limiting seats on both sides. The support and limiting seats include a first support plate that is perpendicular to the base plate and a second support plate that is bent and connected to the top of the first support plate. The second support plate is inclined and is used to abut against the foot pedal.

[0007] The support limiting seat also includes a limiting plate that is bent and connected to the front end face of the first support plate, and the limiting plate is used to abut against the second connecting bracket.

[0008] Both the second support plate and the limiting plate are equipped with cushioning cotton.

[0009] Magnetic induction plates are installed on the first slider and the second slider, and a position sensor that cooperates with the magnetic induction plates is provided on the base plate.

[0010] The lead screw is equipped with limit blocks at both ends.

[0011] The end of the lead screw away from the motor is a prism interface. An emergency maintenance panel is detachably installed on the foot pedal. After the emergency maintenance panel is removed, an inspection port corresponding to the prism interface is exposed on the foot pedal.

[0012] The base plate is equipped with a backup power supply and a driver. When the power supply is active, the external power supply powers the driver and charges the backup power supply. The driver is used to control the operation of the motor. When the external power supply is interrupted, the backup power supply powers the driver.

[0013] The technical solution of this utility model has the following advantages:

[0014] 1. The adjustable lifting foot pedal device for trains provided by this utility model first drives the lead screw to rotate, thereby driving the first support rod to move through the first slider and the first connecting bracket, realizing the adjustment of the foot pedal angle and height, adapting to operators of different body types. The first support rod and the second support rod arranged in a cross manner form a four-bar linkage mechanism, distributing the force on the foot pedal and avoiding the risk of deformation due to single-point support. In addition, the lead screw and the slide rail are arranged parallel to each other vertically. The slide rail is equipped with a first slider and a second slider. The first slider and the second slider drive the support rod to move through the corresponding connecting bracket. In this way, only one slide rail is required, which has the advantages of simple structure and space saving.

[0015] 2. The adjustable lifting foot pedal device for trains provided by this utility model has rubber wheels that provide a certain buffering effect, preventing the second connecting bracket from deforming due to long-term stress and extending its service life.

[0016] 3. The adjustable lifting foot pedal device for trains provided by this utility model has an inclined second support plate that abuts against the foot pedal to limit the foot pedal from being lowered too much and prevent damage to the motor. Furthermore, by setting buffer cotton, the impact force between the foot pedal and the second support plate, and between the limiting plate and the second connecting bracket, can be reduced, thereby improving the comfort of operation.

[0017] 4. The adjustable foot pedal device for trains provided by this utility model automatically switches to backup power after the external power supply is interrupted, ensuring that the foot pedal can still be adjusted in an emergency, and automatically charges the backup power supply when the power supply is normal, avoiding the maintenance burden of regularly replacing batteries.

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Example

[0032] This embodiment provides an adjustable height foot pedal device for trains, such as... Figure 1 and Figure 2 As shown, it includes a foot pedal 1, a base plate 2, and an adjustment mechanism.

[0033] Foot pedal 1 is hinged to base plate 2 at the bottom via a hinge, as shown below. Figure 1 and Figure 7 As shown, an emergency maintenance panel 22 is detachably installed on the foot pedal 1. After the emergency maintenance panel 22 is removed, an inspection port 23 is exposed on the foot pedal 1. A backup power supply 24 and a driver 25 are installed on the base plate 2. In normal power supply mode, the external power input supplies power to the driver 25 and charges the backup power supply 24. The driver 25 is used to control the operation of the motor 3. In the case of power failure, the system can be switched to the backup power supply 24 manually or automatically. The backup power supply 24 supplies power to the driver 25.

[0034] An adjustment mechanism is provided between the foot pedal 1 and the base plate 2, including a motor drive assembly and a lifting assembly driven by the motor drive assembly for driving the foot pedal 1 to rotate relative to the base plate 2.

[0035] Motor drive components, such as Figure 4 and Figure 5 As shown, the system includes a motor 3, a lead screw 4, a slide rail 5, a first slider 6, and a second slider 7, all located in the middle of the base plate 2. The lead screw 4 is driven by the motor 3 and is vertically parallel to the slide rail 5. Both the first slider 6 and the second slider 7 are slidably connected to the slide rail 5, and the first slider 6 is driven by the lead screw 4. Magnetic induction plates 18 are mounted on the first slider 6 and the second slider 7, such as... Figure 3 As shown, the base plate 2 is provided with a position sensor 19 that cooperates with the magnetic induction sheet 18, and the two ends of the lead screw 4 are provided with limiting blocks 20. In this embodiment, as... Figure 5 and Figure 7 As shown, the end of the lead screw 4 away from the motor 3 is a prism interface 21. The prism interface 21 is correspondingly provided with the inspection port 23. The lead screw 4 can be driven to rotate by inserting a sleeve into the prism interface 21.

[0036] Lifting components, such as Figure 3 and Figure 4 As shown, the system includes a first connecting bracket 8, two first support rods 9, a second connecting bracket 10, and two second support rods 11. The first connecting bracket 8 is fixed to the first slider 6. The two first support rods 9 are installed on both sides of the first connecting bracket 8, with their ends respectively connecting the first connecting bracket 8 and the middle of the foot pedal 1. The second connecting bracket 10 is fixed to the second slider 7, and its two ends extend to both ends of the base plate 2. Figure 2As shown, rubber wheels 12 that contact the base plate 2 are installed at both ends of the second connecting bracket 10. When the foot only steps on the side edge of the foot pedal 1, the foot pedal 1 is prone to tilting, which can easily deform and damage the second connecting bracket 8. The rubber wheels can support the second support rod 11 and the foot pedal 1, extending their service life. Two second support rods 11 are installed on both sides of the second connecting bracket 10, with their ends connected to the first connecting bracket 8 and the foot pedal 1, respectively. The first support rod 9 and the second support rod 11 are arranged crosswise. Figure 5 As shown, when the motor 3 drives the lead screw 4 to rotate, causing the first slider 6 and the first connecting bracket 8 to move towards the motor 3 (moving to the left), the first connecting bracket 8 drives the foot pedal 1 to descend through the first support rod 9. When the foot pedal 1 descends, it drives the second connecting bracket 10 and the second slider 7 to move away from the motor 3 (moving to the right) through the second support rod 11.

[0037] The motor 3 is provided with support and limiting seats 13 on both sides, such as Figure 2 and Figure 6 As shown, the support limiting seat 13 includes a first support plate 14 perpendicularly disposed to the base plate 2, a second support plate 15 bent and connected to the top of the first support plate 14, and a limiting plate 16 bent and connected to the front end face of the first support plate 14. The second support plate 15 is inclined and is used to abut against the foot pedal 1, and the limiting plate 16 is used to abut against the second connecting bracket 10. Both the second support plate 15 and the limiting plate 16 are equipped with cushioning cotton 17.

[0038] The adjustable lifting foot pedal device for trains of this utility model includes three working modes:

[0039] Under normal external power supply, the external power supply input supplies power to the driver 25, the driver 25 controls the motor 3 to work, and the motor 3 controls the lifting component to work.

[0040] When the external power supply is interrupted, the system switches to the backup power supply 24. The backup power supply 24 supplies power to the driver 25, and the driver 25 controls the motor 3 to work. The motor 3 then controls the lifting assembly to work.

[0041] In the state of complete power failure, disassemble the emergency maintenance panel 22, connect the special sleeve 26 to the prism interface 21 of the lead screw 4, and drive the lifting assembly to work.

[0042] The adjustable lifting foot pedal device for trains provided by this utility model first drives the lead screw 4 to rotate, thereby driving the first support rod 9 to move through the first slider 6 and the first connecting bracket 8, realizing the adjustment of the foot pedal angle and height to accommodate operators of different body types. The first support rod 9 and the second support rod 11, which are arranged in a cross manner, form a four-bar linkage mechanism to distribute the force on the foot pedal 1 and avoid the risk of deformation due to single-point support. In addition, the lead screw 4 and the slide rail 5 are arranged parallel to each other vertically. The slide rail 5 is equipped with a first slider 6 and a second slider 7. The first slider 6 and the second slider 7 drive the support rod to move through the corresponding connecting bracket. In this way, only one slide rail is required, which has the advantages of simple structure and space saving.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
