Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In one embodiment, see Figures 1-8 A telescopic pedal includes a base plate 5, with side plates 1 arranged on the sides of the base plate 5. The base plate 5 is horizontally positioned, and the side plates 1 are vertically arranged at both ends of the base plate 5. The ends of the side plates 1 are inclined. Protective inclined plates 2 are arranged at the left and right ends of the side plates 1, and the bottom of the protective inclined plates 2 are fixedly connected to the base plate 5. A left-right oriented sliding groove 12 is arranged above the side plates 1. A front-back oriented transverse sliding plate 6 is slidably connected to the middle of the sliding groove 12. The transverse sliding plate 6 moves left and right along the sliding groove 12. A hinge is provided at one end, connecting the left end of the extended pedal 4 via the hinge. A protective top plate 3 is provided at the top of the side plate 1, and the extended pedal 4 is located below the protective top plate 3. During the lateral movement of the transverse plate 6, the extended pedal 4 also moves laterally. A rotating shaft 9 is provided at both ends of the side plate 1, and a synchronous pulley 10 is fixedly connected to the rotating shaft 9. A conveyor synchronous belt 11 is sleeved on the outside of the synchronous pulley 10. When the conveyor synchronous belt 11 rotates, the transverse plate 6 moves with the conveyor synchronous belt 11. An upper clamping plate 22 is provided on the lower surface of the transverse plate 6, and a lower clamping plate 21 that cooperates with the conveyor synchronous belt 11 is detachably connected to the upper clamping plate 22. The upper clamping plate 22 and the lower clamping plate 21 fix the transverse plate 6 to the conveyor synchronous belt 11, thereby achieving the effect of the transverse plate 6 moving with the conveyor synchronous belt 11.

[0027] In one embodiment, auxiliary support plates 7 facing left and right are provided on the front and rear sides of the upper surface of the base plate 5. Auxiliary support wheels 8 are provided at the upper end of the auxiliary support plates 7. When the extended pedal 4 is above the base plate 5, the lower surface of the extended pedal 4 will fall on the auxiliary support wheels 8, so that the extended pedal 4 can remain straight and move horizontally above the base plate 5. However, when the extended pedal 4 moves to the left or right side, the extended pedal 4 disengages from the auxiliary support wheels 8. At this time, the right end of the extended pedal 4 deflects downward under the action of gravity, and the right end of the extended pedal 4 can fall on the ground. Contact sensors 23 are installed at both ends of the auxiliary support plate 7 on the rear side, and contact probes 24 that cooperate with the contact sensors 23 are installed on the lower surface of the transverse plate 6. The position recognition of the transverse plate 6 is achieved through the cooperation of the contact probes 24 and the contact sensors 23. That is, during the movement of the transverse plate 6, when the transverse plate 6 moves to the leftmost end, the contact probes 24 contact the leftmost contact sensor 23. At this time, after the relevant control software recognizes the position of the transverse plate 6, it can control the transverse plate 6 to stop, realizing the effect of automated movement. Similarly, when the transverse plate 6 moves to the rightmost end, the contact probes 24 contact the rightmost contact sensor 23, and the transverse plate 6 can stop automatically again.

[0028] In one embodiment, a drive motor 13 is mounted on the base plate 5. The output shaft of the drive motor 13 is fixedly connected to the middle of the transmission rod 14, and the end of the transmission rod 14 is fixedly connected to the rotating shaft 9. The drive motor 13 drives the rotating shaft 9 to rotate via the transmission rod 14, thereby moving the transverse plate 6. The drive motor 13, in conjunction with the aforementioned contact sensor 23, can achieve automated control. Furthermore, a manual drive assembly 20 is mounted on the left side of the side plate 1. In the event of a power outage or a malfunction of the drive motor 13, the transverse plate 6 can be manually moved using the manual drive assembly 20. The manual drive assembly 20 includes a fixed block 15 fixedly connected to the side plate 1. A rotating shaft 18 is rotatably connected to the fixed block 15. A triangular fixed block 19 is mounted at one end of the rotating shaft 18, and a drive gear 16 is fixedly connected to the other end of the rotating shaft 18. The drive gear 16 meshes with a driven gear 17 fixedly connected to the transmission rod 14. The operator can rotate the triangular fixed block 19 to rotate the transmission rod 14, thereby moving the transverse plate 6.

[0029] In this embodiment, the base plate 5 is fixed to the train floor. When the train stops at the station, the drive motor 13 is started. The drive motor 13 drives the transverse plate 6 to move to the right, and the transverse plate 6 drives the extended pedal 4 to move to the right. The extended pedal 4 extends from under the protective top plate 3. When the transverse plate 6 moves to the rightmost end, the extended pedal 4 disengages from the auxiliary support wheel 8. At this time, the right end of the extended pedal 4 falls onto the platform ground under the action of gravity, and the extended pedal 4 is fully extended. When the train needs to move, the drive motor 13 is started in reverse, and the transverse plate 6 moves to the left. The transverse plate 6 pulls the extended pedal 4 to the left, and the extended pedal 4 moves into the interior of the protective top plate 3, at which point the entire extended pedal 4 is retracted.

[0030] This utility model applies to a telescopic step. By using a transverse plate 6 to drive the movement of the extendable step 4, the extendable step 4 can be automatically extended when the train stops at the station. Furthermore, due to the rotatable connection between the transverse plate 6 and the extendable step 4, the extendable step 4 can adaptively land on the platform ground after being fully extended, thus making the use of the entire telescopic step more convenient.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
