In addition to ensuring the safety of passengers, the train windshield also has longitudinal telescopic performance, which can improve the stability of train operation. When the cars are in any relative position, the windshield maintains close contact to prevent wind, sand, rain, snow, dust, etc. from entering the car. The windshield plays a very important role in the coupling and operation of the train.

[0024] In some implementations of this embodiment, any connecting mechanism includes a long axis 501 and two sets of telescopic mechanisms 502 symmetrically arranged on the long axis 501, both ends of the long axis 501 are slidably connected with sliders 503, two support seats 504 are symmetrically arranged on the connecting frame 401, and any support seat 504 is provided with a sliding groove for the slider 503 to slide; a locking piece 505 is arranged on the slider 503; one end of the telescopic mechanism 502 is connected to the transition plate 201, and the other end is connected to the corresponding slider 503.

[0025] Specifically, the telescopic mechanism 502 includes a first connecting rod 5021, a second connecting rod 5022, a first limit block 5023 fixedly connected to the long axis 501, a second limit block 5024 slidably connected to the long axis 501, a first spring 5025 and a second spring 5026, wherein the first limit block 5023 and the second limit block 5024 are arranged at intervals; one end of the first spring 5025 is connected to the first limit block 5023, and the other end is connected to the second limit block 5024. ; One end of the second spring 5026 is connected to the second limit block 5024, and the other end is connected to the slider 503; one end of the first connecting rod 5021 is hinged to the first limit block 5023, and the other end is hinged to the transition plate 201; one end of the second connecting rod 5022 is hinged to the second limit block 5024, and the other end is hinged to the transition plate 201; the hinge point of the first connecting rod 5021 and the transition plate 201, and the hinge point of the second connecting rod 5022 and the transition plate 201 are close together.

[0026] Specifically, the locking member 505 includes a locking hook 5051 and a limiting rod 5052. The locking hook 5051 is hinged to one end of the slider 503 away from the long axis 501; the limiting rod 5052 is arranged at one end of the support seat 504 away from the other support seat 504 and is located in the slide groove.

[0028] Working principle:

[0029] from Figure 3 From the perspective of , when the inner windshield needs to be installed between two trains 301, first place the two sliders 503 in the two slide grooves on the two support seats 504, and then press the transition plate 201 to move the transition plate 201 toward the connection frame 401. In the process of the transition plate 201 moving toward the connection frame 401, the second limit block 5024 moves to the left under the action of the second connecting rod 5022 due to the effect of pressure. During the leftward movement of the second limit block 5024, the first spring 5025 is stretched and the second spring 5026 is compressed. Then the elastic force of the second spring 5026 acts on the slider 503, causing the slider 503 to also move to the left. During the leftward movement of the slider 503, the lock hook 5051 stops moving after being stuck with the limit rod 5052, and then the transition plate 201 stops being pressed. At this time, the slider 503 tends to move rightward under the elastic force of the first spring 5025 and the second spring 5026 , so this elastic force makes the two locking hooks 5051 always stuck together with the two limiting rods 5052 , so that the transition plate 201 is firmly installed on the connecting frame 401 .

[0030] When the transition plate 201 needs to be separated from the connection frame 401 , the two locking hooks 5051 can be disengaged from the two limiting rods 5052 .
