The rotating member 420 is disposed at an end of the expansion joint 412 away from the connecting seat 411, that is, the rotating member 420 moves together with the expansion member 410 during the expansion and contraction process of the expansion member 410, so as to ensure the expansion and contraction and rotation of the first frame 100 and the second frame 200.
Specifically, as shown in fig. 6 and fig. 7, the expansion joint 412 is horizontally arranged, the expansion joint 412 is provided with a shaft hole vertically penetrating through the axis of the expansion joint, and the rotating member 420 is a rotating shaft penetrating through the shaft hole; the rotation shaft is connected to the second frame 200, i.e., a function of rotating the second frame 200 with respect to the first frame 100 is achieved.
Further, the parts of the two ends of the rotating shaft extending out of the shaft holes are respectively connected with a bearing 421, and the bearing 421 is fixedly connected with the second frame 200 through a bearing seat. The bearing 421 and the bearing housing ensure the stability of the connection of the rotation shaft with the second frame 200.
Of course, the rotating member 420 in the present embodiment is not limited to a rotating shaft, and other rotating members such as a turntable may be used.
As shown in fig. 7, in one embodiment, the second frame 200 includes a skeleton 201 and a housing wrapped on the surface of the skeleton 201, the vertical central lines of the upper and lower sides of the skeleton 201 of the second frame 200 are respectively provided with a U-shaped member 202, the U-shaped opening of the U-shaped member 202 faces the telescopic member 410, the rotating shaft is vertically located in the U-shaped member 202, and the bearings 421 are arranged in the U-shaped member 202 in pairs and connected with two ends of the rotating shaft. In this embodiment, since the connection point between the second frame 200 and the rotating shaft is a stress point, the U-shaped member 202 is provided to facilitate the installation of the bearing seat, and to enhance the connection strength between the second frame 200 and the rotating shaft, thereby ensuring the structural strength and stability of the windshield.
It should be noted that, in the embodiment of the present invention, the first frame 100 and the second frame 200 are movably connected mechanical structures, in order to ensure the tightness of the windshield, the first frame 100 and the second frame 200 must be sealed, and corresponding mechanical movable structures may be disposed between the first frame 100 and the second frame 200 to move according to the first frame 100 and the second frame 200 so as to compensate for the gap between the first frame 100 and the second frame 200.
Alternatively, the first frame 100 and the second frame 200 are connected in a sleeved connection manner, and the maximum distance of the movement of the first frame 100 and the second frame 200 does not generate a gap in the running direction of the train although the first frame 100 and the second frame 200 are relatively movable.
The following embodiments will provide a way to compensate for the gap between the first frame 100 and the second frame 200.
The mechanical outer windshield unit of this embodiment is further provided with a compensation member 300 because the first frame 100 and the second frame 200 are connected by a mechanical structure, and a gap is generated between the first frame 100 and the second frame 200 due to movement.
As shown in fig. 1 to 3, the compensator 300 is disposed between the first frame 100 and the second frame 200, wherein a side of the compensator 300 adjacent to the first frame 100 extends into the first frame 100, and a side of the compensator 300 adjacent to the second frame 200 extends into the second frame 200.

At the same time, the size of the compensator 300 can be reduced correspondingly, and the space can be fully utilized.
The elastic member 500 in this embodiment may have the same structure as the telescopic member 410, that is, the elastic member 500 includes a connecting seat 411 and an telescopic joint 412, the connecting seat 411 is fixedly connected to the first frame 100, the telescopic joint 412 is connected to the connecting seat 411 through a spring 413, and one end of the telescopic joint 412 is connected to the compensating member 300, so that the compensating member 300 moves relative to the first frame 100 through the telescopic joint 412 and the spring 413 to implement the telescopic function of the compensating member 300.
Of course, the elastic member 500 may also be made of elastic material, such as rubber, sponge, or a spring structure, and is not limited only herein.
