[0022] 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.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in one embodiment of this utility model, a universal step device for boarding and alighting on subway passenger service trains is proposed, comprising a housing 1, a step body 2, and a drive assembly 3. The step body 2 is slidably disposed in a receiving cavity formed inside the housing 1, facilitating stable installation of the step body 2. It is unfolded from the housing 1 for use and stably stored back in the housing 1 after use. A movable groove 202 for mounting the drive assembly 3 is provided at the lower part of the step body 2, facilitating stable installation of the drive assembly 3 onto the lower part of the step body 2. Thus, during use, the drive assembly 2 moves within the housing... 1. Smooth sliding: One end of the drive rod 301 of the drive assembly 3 is equipped with a second slider 302. The second slider 302 is slidably connected to the second slide groove 203 opened in the rod movable groove 202. The other end of the drive rod 301 is fixedly connected to the bottom of the subway car door through the connecting shaft 305. This facilitates the transmission of the power of the car door opening and closing to the pedal body 2 through the drive assembly 3 during the opening and closing of the subway car door. This enables the pedal body 2 to be smoothly unfolded and used, as well as stored. When the car door is opened, the pedal body 2 is unfolded and used. When the car door is closed, the pedal body 2 is stored.

[0025] The entire pedal device is stably installed on the floor at the door of the carriage using the housing 1, so that it fits into the carriage floor and remains on the same plane, thus avoiding unevenness in the interior floor of the carriage.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, a first sliding groove 101 is provided in the internal cavity of the housing 1. A first slider 201 provided on the pedal body 2 extends into the first sliding groove 101 and is slidably connected with the first sliding groove 101. By utilizing the cooperation of the first slider 201 and the first sliding groove 101, the stability of the pedal body 2 sliding in the housing 1 is improved. At the same time, the first slider 201 is used to restrict the sliding path of the pedal body 2, preventing the pedal body 2 from sliding off the housing 1 and ensuring that the two can cooperate stably with each other.

[0027] like Figure 1 and Figure 3As shown, in some embodiments, an inclined baffle 4 is fixedly connected to one side of the pedal body 2 outside the housing 1, which facilitates the formation of a slope at the edge of the plate body, avoiding the formation of a more obvious step at the edge of the plate body when the pedal body 2 is unfolded and used, thereby improving the comfort of use. In addition, the rod movable groove 202 is set one-to-one with the drive assembly 3, which facilitates the formation of an area on the pedal body 2 that can accommodate the smooth movement of the drive rod 301, thereby enabling the drive rod 301 to move smoothly and transmit power.

[0028] like Figure 1 and Figure 4 As shown, in some embodiments, a plug-in seat 303 is integrally provided on the second slider 302 at one end of the drive rod 301. The plug-in seat 303 is slidably connected in the second slide groove 203, and the connecting pin 304 passes through the through hole opened at the end of the drive rod 301 and is fixedly plugged into the plug-in seat 303. The connecting pin 304 is rotatably connected to the drive rod 301, so that appropriate rotation can be generated between the two during the driving process, thereby achieving the purpose of smooth driving. The second slider 302 is stably connected to the end of the drive rod 301 by the connecting pin 304, thereby forming a connecting component at the end of the drive rod 301 that can stably cooperate with the second slide groove 203. Thus, the drive rod 301 can smoothly slide the second slider 302 in the second slide groove 203, and the second slider 302 pushes against the side wall of the second slide groove 203 during the sliding process, thereby driving the pedal body 2 to slide out in the housing 1, so that it can be smoothly unfolded for use, or the pedal body 2 can be smoothly stored in the housing 1 after use.

[0029] The other end of the drive rod 301 has a through hole for inserting a connecting shaft 305. The connecting shaft 305 is fixedly connected to the lower part of the side that moves into the car wall during the opening and closing of the subway car door. The connecting shaft 305 is rotatably connected to the drive rod 301, so that the two can rotate appropriately during the driving process, thereby achieving the purpose of smooth driving. During the opening or closing of the subway car door, the connecting shaft 305 moves the drive rod 301 together, so that the power of the door opening and closing is transmitted to the pedal body 2 through the drive assembly 3. With the opening and closing of the door, the pedal body 2 can be displayed and stored in the housing 1.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
