[0018] The present invention provides a pedal device for a subway door system in mechatronic engineering through improvement. Compared with the prior art, it has the following improvements and advantages:

[0019] First: Through the setting of the driving mechanism in the present invention, after the cleaning seat moves downward, the driving motor can be started. The driving motor drives the driving wheel to rotate, and the rotation of the driving wheel can squeeze the cleaning seat. Since the cleaning seat is installed inside the subway carriage through the hydraulic rod, the connecting rod and the connecting seat, and the connecting rod can move inside the connecting seat, the cleaning seat can move back and forth through the cyclic squeezing of the two driving wheels. At this time, the first cleaning brush contacts the pedal and the anti-slip groove, and the back-and-forth movement of the cleaning seat driven by the first cleaning brush can clean the surfaces of the pedal and the anti-slip groove, improving the cleaning effect on the pedal and the anti-slip groove and avoiding the situation where the anti-slip effect of the anti-slip groove decreases.

[0020] Second: The present invention is provided with a cleaning mechanism. When the dust and impurities on the surfaces of the pedal and the anti-slip groove are cleaned, the air pump can be started. The air pump generates suction inside the cleaning pipe through the pneumatic pipe. The suction inside the cleaning pipe can be conducted to the inside of the cleaning seat through the movable pipe and the collecting pipe. The cleaning seat can then suck the dust and impurities cleaned from the surfaces of the pedal and the anti-slip groove into the inside of the cleaning seat through the collecting port, and then be sucked into the inside of the movable pipe and the cleaning pipe by the collecting pipe. Thus, while improving the cleaning effect on the pedal and the anti-slip groove, it can also collect the cleaned dust and impurities.

[0021] Third: In the present invention, through the setting of the wind blade, when the outside air moves inside the air inlet and the air outlet, the wind blade will rotate, thereby driving the rotating shaft to rotate. The rotating shaft can drive the second cleaning brush to rotate, and the rotation of the second cleaning brush can clean the surface of the filter element, thus achieving the effect of automatically cleaning the filter element during driving and avoiding the situation where the collection effect deteriorates due to the filter element being blocked by dust.

[0022] Fourth: In the present invention, through the setting of the air storage pipe, when the pedal extends towards the outside, the pedal can drive the piston plate to move inside the air storage pipe through the push rod. At this time, the outside air can be sucked into the inside of the air storage pipe through the second air inlet pipe. Then, when the pedal retracts towards the inside of the inner groove, the pedal can drive the piston plate to move inside the air storage pipe. At this time, the air inside the air storage pipe will be squeezed into the inside of the second air outlet pipe, and then enter the inside of the cleaning seat through the air supply hole, and then be discharged from the inside of the cleaning seat through the collecting port. At this time, the inside of the collecting port can be cleaned to avoid the situation where the inside of the collecting port is blocked by dust and impurities. Subsequently, the cleaning seat can move downward to clean the pedal and the anti-slip groove, thereby improving the cleaning effect next time. Description of the Drawings

Detailed implementation manners

[0036] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] The present invention provides a pedal device for a subway door system in mechatronic engineering by improvement. The technical solution of the present invention is as follows:

[0038] As Figures 1 to 8 shown, the embodiment of the present invention provides a pedal device for a subway door system in mechatronic engineering, including a subway carriage 1. Two subway doors 2 are movably installed inside the subway carriage 1. An inner groove 3 is opened at a position corresponding to the subway door 2 below the side wall of the subway carriage 1. The inner groove 3 is a groove with a rectangular structure. A pedal 4 is movably installed inside the inner groove 3 through a hydraulic device. When the subway door 2 is opened, the pedal 4 will be driven by the hydraulic device to move out from the inside of the inner groove 3. A plurality of anti-slip grooves 5 are opened on the pedal 4. The anti-slip grooves 5 are long grooves with a rectangular structure. The anti-slip grooves 5 can play an anti-slip effect when a pedestrian steps on the pedal 4. A support frame groove 6 is opened at a position corresponding to the pedal 4 below the side wall of the subway carriage 1. A support frame 7 is arranged inside the support frame groove 6. The support frame 7 is fixedly connected to the pedal 4. The support frame 7 can support the pedal 4. A cleaning mechanism and a driving mechanism are arranged inside the subway carriage 1;

[0039] The driving mechanism includes a hydraulic rod 11, a connecting rod 12, a connecting seat 13, a driving motor 14 and a driving wheel 15. There are two sets of the hydraulic rod 11, the connecting rod 12 and the connecting seat 13. The two sets of hydraulic rods 11 are symmetrically embedded and installed above the inside of the installation groove 8. The connecting rod 12 is of a cylindrical structure and is fixedly installed at the output end of the hydraulic rod 11. The connecting seat 13 is of a hollow rectangular structure and is fixedly installed on the top wall surface of the cleaning seat 9. One end of the connecting rod 12 is located inside the connecting seat 13, and a rectangular groove for one end of the connecting rod 12 is provided on the connecting seat 13. The cleaning seat 9 is installed inside the installation groove 8 through the hydraulic rod 11, the connecting rod 12 and the connecting seat 13. When the pedal 4 is retracted into the inner groove 3, the hydraulic rod 11 can be started. The hydraulic rod 11 drives the cleaning seat 9 to move downward through the connecting rod 12. At this time, the first cleaning brush 10 at the bottom of the cleaning seat 9 will contact the pedal 4 and the anti-slip groove 5. There are two driving motors 14 and two driving wheels 15. The two driving motors 14 are both embedded and installed at the corresponding positions of the cleaning seat 9 inside the subway car 1. The two driving motors 14 are respectively located on both sides of the cleaning seat 9. The driving wheel 15 is a circular plate with protrusions. The two driving wheels 15 are respectively connected to the output ends of the two driving motors 14, and the protrusions of the two driving wheels 15 are in opposite directions. Through the setting of the driving mechanism, after the cleaning seat 9 moves downward, the driving motor 14 can be started. The driving motor 14 drives the driving wheel 15 to rotate. The rotation of the driving wheel 15 can squeeze the cleaning seat 9. Since the cleaning seat 9 is installed inside the subway car 1 through the hydraulic rod 11, the connecting rod 12 and the connecting seat 13, and the connecting rod 12 can move inside the connecting seat 13, the cleaning seat 9 can be moved back and forth through the cyclic squeezing of the two driving wheels 15. At this time, the first cleaning brush 10 contacts the pedal 4 and the anti-slip groove 5. The back-and-forth movement of the cleaning seat 9 driving the first cleaning brush 10 can clean the surfaces of the pedal 4 and the anti-slip groove 5, improving the cleaning effect on the pedal 4 and the anti-slip groove 5 and avoiding the occurrence of the situation that the anti-slip effect of the anti-slip groove 5 decreases;

[0040] The cleaning mechanism includes a cleaning base 9, a first cleaning brush 10, a treatment box 16, an air pump 17, a pneumatic tube 18, a cleaning tube 19, a movable tube 20, and a collection tube 21. The cleaning base 9 is a plate with a hollow rectangular structure. An installation groove 8 is formed above the inner part of the inner groove 3. The installation groove 8 is a groove with a rectangular structure. The cleaning base 9 is arranged inside the installation groove 8. The first cleaning brush 10 is a long strip with a rectangular structure. There are multiple first cleaning brushes 10. The multiple first cleaning brushes 10 are evenly fixedly installed at the bottom of the cleaning base 9. The position distribution of the first cleaning brushes 10 corresponds to the position of the anti-slip grooves 5. The treatment box 16 is a hollow rectangular structure. The treatment box 16 is inlaid and installed at the bottom of the subway car body 1. The air pump 17 is arranged inside the treatment box 16. The pneumatic tube 18 is an "L"-shaped tube. The pneumatic tube 18 is connected to the input end of the air pump 17. The cleaning tube 19 is a hollow cylindrical tube. There are four cleaning tubes 19. The four cleaning tubes 19 are horizontally inlaid and installed above the inner part of the installation groove 8. The movable tube 20 is a cylindrical tube. There are three movable tubes 20. The three movable tubes 20 are respectively movably installed between the four cleaning tubes 19. Both ends of the movable tube 20 are located inside the cleaning tubes 19. The collection tube 21 is a cylindrical tube. The collection tube 21 is fixedly installed at the bottom of the movable tube 20. And the bottom of the collection tube 21 penetrates through the top wall surface of the cleaning base 9 and is located inside the cleaning base 9. The bottom wall surface of the cleaning base 9 is evenly provided with a plurality of collection ports 22. The collection ports 22 are circular holes. Through the setting of the driving mechanism, the cleaning base 9 can be driven to move and clean on the pedal 4 and the anti-slip grooves 5. When the dust and impurities on the surfaces of the pedal 4 and the anti-slip grooves 5 are cleaned off, the air pump 17 can be started. The air pump 17 generates suction inside the cleaning tube 19 through the pneumatic tube 18. The suction inside the cleaning tube 19 can be conducted to the inside of the cleaning base 9 through the movable tube 20 and the collection tube 21. The cleaning base 9 can then suck the dust and impurities cleaned off from the surfaces of the pedal 4 and the anti-slip grooves 5 into the inside of the cleaning base 9 through the collection ports 22, and then be sucked into the inside of the movable tube 20 and the cleaning tube 19 by the collection tube 21. Thus, while improving the cleaning effect on the pedal 4 and the anti-slip grooves 5, the dust and impurities cleaned off can also be collected.

[0041] A first air outlet pipe 23 is fixedly installed on the output end of the air pump 17. The first air outlet pipe 23 penetrates through the bottom of the processing box 16 and communicates with the outside. A first air inlet pipe 24 is installed on the output end of the air pump 17. The first air inlet pipe 24 is a cylindrical pipe. The first air inlet pipe 24 penetrates through the side wall of the pneumatic pipe 18 and communicates with the inside of the pneumatic pipe 18. A filter element 25 is installed at one end of the first air inlet pipe 24 close to the pneumatic pipe 18. The filter element 25 can filter the inhaled air. A collection mechanism is arranged inside the processing box 16. The collection mechanism includes a collection box 30, a torsion spring shaft 32, a sealing plate 33 and a baffle plate 34. The collection box 30 is a hollow rectangular structure. The collection box 30 is fixedly installed inside the processing box 16.

The sealing plate 33 is fixedly sleeved on the torsion spring shaft 32. The sealing plate 33 can seal the pneumatic pipe 18. The baffle plate 34 is an inclined semi-circular plate. The baffle plate 34 is fixedly installed above the position corresponding to the first air inlet pipe 24 inside the pneumatic pipe 18. Through the setting of the collection mechanism, after the air with dust and impurities enters the inside of the pneumatic pipe 18, the air is filtered by the filter element 25, and the filtered air can be discharged to the outside through the first air outlet pipe 23, while the dust and impurities will be blocked by the filter element 25 and the baffle plate 34. When the air pump 17 stops operating, the dust and impurities will fall onto the sealing plate 33 under the action of gravity, and then the sealing plate 33 can be turned over, so that the dust and impurities fall into the inside of the collection box 30 to be collected.

[0042] The driving mechanism further includes a telescopic sleeve 26, a telescopic rod 27, a limiting plate 28 and a limiting block 29. The telescopic sleeve 26 is a hollow cylindrical structure.

The limiting block 29 is a rectangular strip. The limiting block 29 is fixedly installed at the bottom of the telescopic rod 27, and the limiting block 29 is movably connected with the telescopic sleeve 26. When the cleaning seat 9 moves up and down, due to the connection between the telescopic rod 27 and the limiting plate 28, the driving wheel 15 can be driven to move up and down when the cleaning seat 9 moves up and down, so that the driving wheel 15 can always move up and down with the cleaning seat 9. At the same time, the telescopic sleeve 26 and the telescopic rod 27 are connected by the limiting block 29, so that the telescopic rod 27 can move up and down inside the telescopic sleeve 26 and can also rotate with the telescopic sleeve 26, so that the driving wheel 15 can rotate while moving up and down with the cleaning seat 9 to squeeze the cleaning seat 9.

[0043] An air inlet 35 and an air outlet 36 are provided at the bottom of the subway car 1 corresponding to the position of the treatment box 16. The inside of the air inlet 35 and the air outlet 36 is connected, and the bottom of the air inlet 35 is an inclined surface. Thus, when the subway car 1 is running, the outside air can enter the inside of the air inlet 35 through the inclined surface at the bottom of the air inlet 35, and then can be discharged from the inside of the air outlet 36 through the air outlet 36. A rotating shaft 37 is movably installed inside the air inlet 35 and the air outlet 36. The rotating shaft 37 is of a cylindrical structure. One end of the rotating shaft 37 penetrates the side walls of the treatment box 16 and the pneumatic pipe 18 and is located inside the treatment box 16 and the pneumatic pipe 18.

Through the arrangement of the wind blade 39, when the outside air moves inside the air inlet 35 and the air outlet 36, the wind blade 39 will rotate, thereby driving the rotating shaft 37 to rotate. The rotating shaft 37 can drive the second cleaning brush 38 to rotate. The rotation of the second cleaning brush 38 can clean the surface of the filter element 25, so as to achieve the effect of automatically cleaning the filter element 25 during driving, and avoid the situation that the collection effect becomes poor due to the filter element 25 being blocked by dust.

[0044] Inside the subway car 1, a gas storage pipe 40 is inlaid and installed at the position corresponding to the pedal 4. The gas storage pipe 40 is of a hollow cylindrical structure. A piston plate 41 is movably installed inside the gas storage pipe 40. The piston plate 41 is a circular plate with the same size as the inside of the gas storage pipe 40. A push rod 42 is fixedly installed on the piston plate 41. The push rod 42 is a cylindrical rod. The push rod 42 penetrates through the side wall of the gas storage pipe 40 and is fixedly connected to the pedal 4. On the other side of the gas storage pipe 40, a second intake pipe 43 is fixedly installed. The second intake pipe 43 is a cylindrical pipe. The second intake pipe 43 penetrates downward through the bottom wall of the subway car 1 and communicates with the outside. At the position of the gas storage pipe 40 corresponding to the second intake pipe 43, a second outlet pipe 44 is fixedly installed. The second outlet pipe 44 is an "L"-shaped pipe. The other end of the second outlet pipe 44 corresponds to the position of the cleaning seat 9. First check valves 45 are installed on both the second intake pipe 43 and the second outlet pipe 44. At the position of the side wall of the cleaning seat 9 corresponding to the second outlet pipe 44, an air supply hole 46 is opened. The air supply hole 46 is a circular hole. The air supply hole 46 enables the second outlet pipe 44 to communicate with the inside of the cleaning seat 9. An activity plate 47 is movably installed inside the cleaning seat 9 at the position corresponding to the second outlet pipe 44. The activity plate 47 is a rectangular plate. The activity plate 47 can seal the air supply hole 46. A second check valve 48 is fixedly installed below the inside of the collection pipe 21. Through the setting of the gas storage pipe 40, when the pedal 4 extends towards the outside, the pedal 4 can drive the piston plate 41 to move inside the gas storage pipe 40 through the push rod 42. At this time, outside air can be inhaled into the inside of the gas storage pipe 40 through the second intake pipe 43. Then when the pedal 4 retracts towards the inside of the inner groove 3, the pedal 4 can drive the piston plate 41 to move inside the gas storage pipe 40 through the push rod 42. At this time, the air inside the gas storage pipe 40 will be squeezed into the inside of the second outlet pipe 44, and then can enter the inside of the cleaning seat 9 through the air supply hole 46, and then can be discharged from the inside of the cleaning seat 9 through the collection port 22. At this time, the inside of the collection port 22 can be cleaned, avoiding the situation that the inside of the collection port 22 is blocked by dust and impurities. Subsequently, the cleaning seat 9 can move downward to clean the pedal 4 and the anti-slip groove 5, thereby improving the cleaning effect next time.

[0045] Specific implementation steps: Through the setting of the driving mechanism, when the cleaning seat 9 moves downward, the driving motor 14 can be started. The driving motor 14 drives the driving wheel 15 to rotate, and the rotation of the driving wheel 15 can squeeze the cleaning seat 9. Since the cleaning seat 9 is installed inside the subway car 1 through the hydraulic rod 11, the connecting rod 12 and the connecting seat 13, and the connecting rod 12 can move inside the connecting seat 13, the cleaning seat 9 can be moved back and forth through the cyclic squeezing of the two driving wheels 15. At this time, the first cleaning brush 10 contacts the pedal 4 and the anti-slip groove 5. The back-and-forth movement of the cleaning seat 9 driving the first cleaning brush 10 can clean the surfaces of the pedal 4 and the anti-slip groove 5, improving the cleaning effect on the pedal 4 and the anti-slip groove 5 and avoiding the situation of the anti-slip effect of the anti-slip groove 5 decreasing;

[0046] Meanwhile, a cleaning mechanism is provided. When the dust and impurities on the surfaces of the pedal 4 and the anti-slip groove 5 are cleaned, the air pump 17 can be started. The air pump 17 generates suction inside the cleaning pipe 19 through the pneumatic pipe 18. The suction inside the cleaning pipe 19 can be conducted to the inside of the cleaning seat 9 through the movable pipe 20 and the collecting pipe 21. The cleaning seat 9 can then suck the dust and impurities cleaned from the surfaces of the pedal 4 and the anti-slip groove 5 into the inside of the cleaning seat 9 through the collecting port 22, and then be sucked into the inside of the movable pipe 20 and the cleaning pipe 19 by the collecting pipe 21. Thus, while improving the cleaning effect on the pedal 4 and the anti-slip groove 5, it can also collect the cleaned dust and impurities.
