[0038] In order to more clearly explain the above-mentioned purposes, features and advantages of the present application, the specific implementation methods of the present application are described in detail in this section in conjunction with the accompanying drawings. In addition to the various implementation methods described in this section, the present application can also be implemented in other different ways. Without violating the spirit of the present application, those skilled in the art can make corresponding improvements, deformations and substitutions, so the present application is not limited by the specific embodiments disclosed in this section. The scope of protection of the present application shall be subject to the claims.

[0039] like Figures 1 to 6 As shown, the present application proposes a platform sliding door group, which is used for the platform of a rail vehicle. The platform sliding door group includes a fixed door 1, an adjustable door 2, a sliding door 3, a column 4, a threshold 5, a driving mechanism 6, a door machine beam 7 and a guide mechanism 8.

[0040] The column 4 can be connected to the platform, in particular fixed to the platform. The fixed door 1 is connected to the column 4, and the column 4 is used to support the fixed door 1 so that the fixed door 1 can be installed on the platform. The fixed door 1 can serve as an isolation barrier for the platform. A door opening is formed between the two fixed doors 1 that are spaced apart, and passengers can get on and off through the door opening. The width of the door opening can be greater than the spacing between the train doors of different models of trains, so that when trains of different models stop at the platform, the train doors can all be aligned with the door opening.

[0041] The adjustment door 2 and the sliding door 3 are connected to the door machine beam 7. The adjustment door 2 and the sliding door 3 are arranged in parallel. The door machine beam 7 is connected to the driving mechanism 6. The driving mechanism 6 can drive the adjustment door 2 and the sliding door 3 to move together by driving the door machine beam 7. The adjustment door 2 has two leaves, and the two adjustment doors 2 are respectively located on the left and right sides of the door opening. In the left-right direction X, when the two sliding doors 3 are closed, the adjustment door 2 is located between the fixed door 1 and the sliding door 3, and the adjustment door 2 serves as a platform isolation barrier that can move left and right. Figure 2 As shown, when the sliding door 3 is closed, the sliding door 3 and the adjusting door 2 may only overlap slightly at the edge position or may not overlap substantially. When the sliding door 3 is opened, the sliding door 3 and the adjusting door 2 may overlap substantially.

[0042] The adjustable door 2 is arranged in parallel with the fixed door 1 , and the adjustable door 2 and the fixed door 1 partially overlap, so that the adjustable door 2 can cover a part of the door opening, and the sliding door 3 can cover another part of the door opening.

[0043] The adjusting door 2 may be disposed on the front side (track side) of the fixed door 1 , and the sliding door 3 may be disposed on the front side of the adjusting door 2 .

[0044] The sliding door 3 has two leaves, and the two sliding doors 3 are installed on the pillar 4 or the fixed door 1 in a split manner. The two sliding doors 3 can slide in the left-right direction X (opening and closing direction) to open or close.

[0045] like Figures 3 to 5 As shown, the gantry beam 7 can be located above the adjusting door 2 and the sliding door 3. The adjusting door 2 is connected to the gantry beam 7 through the door connector 22. The sliding door 3 is installed on the gantry beam 7 through the hanger 32. When the gantry beam 7 moves along the linear guide rail 81, the adjusting door 2 and the sliding door 3 can move with the gantry beam 7.

[0046] The door machine beam 7 is equipped with a door machine assembly, and the sliding door 3 can move relative to the door machine beam 7 through the door machine assembly 71, so as to realize the opening and closing of the sliding door 3. The door machine assembly 71 can be composed of an existing door machine assembly.

[0047] like Figures 3 to 6 As shown, the driving mechanism 6 includes a motor 61 , a driving wheel 62 , a driven wheel 63 , a belt 64 , a belt clamp 65 and a belt guide wheel 66 .

[0048] The motor 61 can be fixedly connected to the column 4, the driving wheel 62 is connected to the output shaft of the motor 61, the belt 64 is sleeved on the driving wheel 62 and the passive wheel 63, and the belt 64 can move around the driving wheel 62 and the passive wheel 63 under the drive of the driving wheel 62. The belt clamp 65 is connected to the belt 64 and the door machine beam 7, so that the door machine beam 7 can move with the belt 64.

[0049] The passive wheel 63 can be installed to move along the left-right direction X, and an elastic force in a direction away from the driving wheel 62 can be applied to the passive wheel 63 by an elastic member, so that the passive wheel 63 has a tendency to move away from the driving wheel 62, so that the belt 64 can be kept tensioned. Of course, the present application is not limited to this, and the passive wheel 63 can also be fixed in position. Optionally, the belt 64 can be tensioned by an additional tensioning device.

[0050] The belt guide wheel 66 can be installed in the middle of the driving wheel 62 and the driven wheel 63. The belt guide wheel 66 is used to support the belt 64 to prevent the belt 64 from sagging. The belt guide wheel 66 can also guide the belt 64.

[0051] like Figure 4 and Figure 5 As shown, the guide mechanism 8 includes a guide rail 81, a slider 82 and a guide rail beam 83. The guide rail 81 can be mounted on the column 4 through the guide rail beam 83, the guide rail 81 extends along the left-right direction X, and the slider 82 can be slidably mounted on the guide rail 81 along the guide rail 81. The door machine beam 7 is connected to the slider 82 through the slider mounting bracket 72.

[0052] The guide mechanism 8 can bear the weight and load of the door machine beam 7, the adjustment door 2 and the sliding door 3, and play a guiding role. The door machine beam 7 is connected to the guide rail beam 83 through the guide mechanism 8, so that the door machine beam 7 runs smoothly.

[0053] like Figure 1 , Figure 4 and Figure 6 As shown, the threshold 5 is arranged below the adjusting door 2 and the sliding door 3, and two guide grooves are arranged on the threshold 5. Guide shoes are installed at the bottom of the adjusting door 2 and the sliding door 3, and the guide shoes 21 and 31 of the adjusting door 2 and the sliding door 3 are respectively embedded in the corresponding guide grooves, so that the adjusting door 2 and the sliding door 3 can slide along the guide grooves.

[0054] like Figure 2 As shown, the first train door 100 and the second train door 200 represent the positional relationship between train doors of different models and the platform sliding door group when vehicles of different models are parked at the platform.

[0055] When the train is about to stop, the platform sliding door assembly can receive a signal of the vehicle type. For example, when the first train door 100 needs to be opened, the door machine beam 7 drives the adjustment door 2 and the sliding door 3 to move to the left at the same time, so that the sliding door 3 is aligned with the first train door 100. When the train enters the station and stops, the door machine assembly 71 drives the sliding door 3 to open for passengers to get on and off. During the movement of the door machine beam 7 to the left, the adjustment door 2 and the fixed door 1 on the left side of the door opening overlap more, and the adjustment door 2 and the fixed door 1 on the right side of the door opening are more staggered.

[0056] Similarly, when the second train door 200 needs to be opened, the door machine beam 7 drives the adjustment door 2 and the sliding door 3 to move to the right at the same time, so that the sliding door 3 is aligned with the second train door 200. When the train enters the station and stops, the door machine assembly 71 drives the sliding door 3 to open for passengers to get on and off.

[0057] By moving the adjusting door 2 and the sliding door 3 together, the adjusting door 2 and the sliding door 3 can be translated as a whole before the train stops at the station, and the sliding door 3 moves to the position of the corresponding train door of the incoming train, thereby meeting the parking needs of trains of different models.

[0058] Although the present application is described in detail using the above-mentioned embodiments, it is obvious to those skilled in the art that the present application is not limited to the embodiments described in this specification. The present application can be modified and implemented as a modified embodiment without departing from the subject matter and scope of the present application as determined by the claims. Therefore, the description in this specification is for the purpose of illustration and does not have any restrictive meaning for the present application.
