[0026] AsFigures 1 to 5 As shown, an anti-collision structure for an electric train includes a first support member 1 and a second support member 2, which are symmetrically arranged. Both the first support member 1 and the second support member 2 include a lifting member 5, a sliding plate 6, and a support plate 7. The lifting member 5 includes a sliding frame 51, one end of which is fixed to the carriage by a fixing bolt 53. The sliding plate 6 is horizontally slidably assembled in the sliding frame 51. A hole seat 52 is horizontally fixed through the middle of the other end of the sliding frame 51. A guide rod 61 is horizontally fixed on the sliding plate 6 and is horizontally slidably assembled on the hole seat 52 of the sliding frame 51. The support plate 7 is fixed to one end of the guide rod 61 extending out of the sliding frame 51. A spring 3 is horizontally fixed to the side end face of the support plate 7 of the first support member 1, and a damping element is horizontally fixed to the side end face of the support plate 7 of the second support member 2. The other end of the rod 4 and the spring 3 are fixed to the support plate 7 of the second support member 2, and the other end of the damping rod 4 is fixed to the support plate 7 of the first support member 1. In use, the sliding frame 51 on the lifting members 5 at both ends of the first support member 1 and the second support member 2 is fixed to the adjacent carriages of the electric train by fixing bolts 53. When the adjacent carriages of the electric train experience an inertial impact, the support plate 7 in the first support member 1 and the second support member 2 is squeezed to move. The support plate 7 pushes the pressure column 71 to slide horizontally in the hole seat 52 of the sliding frame 51 and is supported by the pressure rubber column 55. Then, the adjacent support plates 7 of the first support member 1 and the second support member 2 push the spring 3 to deform and absorb the inertial impact force of the carriage. Then, the deformation potential energy of the spring 3 is canceled by the damping force of the damping rod 4, thereby canceling the inertial impact force of the carriage.

[0027] In one embodiment, such as Figure 5 As shown, a rubber column 55 is horizontally arranged inside the slide frame 51, and a stud 56 is horizontally fixed at the bottom end of the rubber column 55. A screw hole seat 54 is horizontally fixed on the bottom surface inside the slide frame 51, and the screw hole seat 54 is threadedly assembled with the stud 56 on the rubber column 55. In use, the stud 56 that presses against the bottom end of the rubber column 55 is threadedly assembled in the screw hole seat 54 of the slide frame 51, thereby pressing against the rubber column 55 to support the slide plate 6 to slide horizontally.

[0028] In one embodiment, such as Figure 4 As shown, two pressure columns 71 are horizontally symmetrically arranged between the sliding frame 51 and the support plate 7 of the first support member 1 and the second support member 2, and the other ends of the two pressure columns 71 are respectively fixed to the adjacent end faces of the sliding frame 51 and the support plate 7. An airbag column 72 is horizontally arranged between the two pressure columns 71, and the two ends of the airbag column 72 are respectively fixed to the adjacent end faces of the two pressure columns 71. When the first support member 1 and the second support member 2 are squeezed and move, the pressure column 71 presses against the airbag column 72 to deform and absorb the impact force.

[0029] In one embodiment, such as Figure 2 and 3As shown, the first support 1 is provided with a guide hole plate 8 at both ends of the supporting plate 7, and the guide hole plate 8 is fixed on the end face of the supporting plate 7; the second support 2 is fixed with a sliding rod 9 at both ends of the supporting plate 7, and the sliding rod 9 is horizontally slidingly assembled in the guide hole plate 8; in use, when the first support 1 and the second support 2 are moved to be closed, the sliding rod 9 is horizontally slidingly moved in the guide hole plate 8, and the horizontal moving is guided by the movement of the sliding rod 9 in the guide hole plate 8.

[0030] In the embodiment, the sliding frame 51 on the both-end supporting member 5 of the first support 1 and the second support 2 is fixed on the adjacent carriages of the electric train through the fixing bolt 53; when the adjacent carriages of the electric train are impacted by inertia, the supporting plate 7 of the first support 1 and the second support 2 is moved by extrusion, the supporting plate 7 pushes the pressing column 71 to be horizontally slidingly moved in the hole seat 52 of the sliding frame 51, and the pressing column 71 is supported by the rubber column 55, then the adjacent supporting plate 7 of the first support 1 and the second support 2 pushes the spring 3 to be deformed to absorb the impact force of the carriage inertia, then the potential energy of the deformed spring 3 is offset by the damping force of the damping rod 4, so that the impact force of the carriage inertia is offset.

[0031] The above is the preferred embodiment of the utility model, and the person skilled in the art of the utility model can also change and modify the above-mentioned embodiment, therefore, the utility model is not limited to the above-mentioned specific embodiment, and any obvious improvement, replacement or modification made by the person skilled in the art on the basis of the utility model belongs to the protection scope of the utility model.
