Specifically, the train end protection device further comprises:

the supporting bodies 3 are arranged on the inner side of the protective cover 1, extend along the axial direction of the protective cover 1 and are distributed on the circumferential direction of the protective cover 1. As shown in fig. 2a, the support bodies 3 are provided in the circumferential direction of the shield 1 in a total of five. Because the protection casing receives self gravity influence when using, flagging easily, the setting of supporter can prevent that the protection casing from flagging, avoids protection casing and coupling to take place to interfere. Therefore, more supporting bodies can be arranged on the inner side of the protective cover above according to the specific force bearing size, so that a stable protective space can be supported better.

Optionally, the protective cover is telescopic and has certain telescopic performance, so that the train end protective device can be contracted when not in use, the space occupied between the train bodies is greatly reduced, and the front-end equipment of the train body is convenient to check and maintain. As shown in fig. 2a, the protection cover is in a retracted state, so that the supporting body inside the protection cover protrudes from two ends of the protection cover, and actually, when the protection cover is extended, the supporting body does not protrude from two ends of the protection cover, and the first connecting body and the second connecting body protrude from two ends of the protection cover to connect with the first vehicle body and the second vehicle body.

As shown in fig. 2a, a carrier 4 is disposed in the shield to support the shield 1 to form a stable shield space. Specifically, the supporting body may be a material having a certain supporting function, such as a spiral steel wire, a spring, or an elastic cord.

As shown in fig. 2b, the first connecting body 21 and the second connecting body 22 are connecting structures 101 disposed at two ends of the protective cover 1. The protective device is connected with the two car bodies through a connecting structure and a bolt, a ribbon, a hook or other modes matched with the connecting structure.

the second connecting unit 22 has a second connecting end 221, and the second connecting end 221 is connected to the second hood 201 of the second vehicle body 20.

Specifically, the first connecting end 211 can be connected to the first hood 101 of the first vehicle body by a bolt, a tie, a hook, or other means, for example, an interface or a component matching the first connecting end 211 can be provided inside the first hood 101. The second attachment end 221 may be attached to the second hood 201 of the second body by bolts, straps, hooks, or other means, such as an interface or feature on the inside of the second hood 201 that mates with the second attachment end 221. As shown in fig. 2a, the first and second connection ends 211 and 221 are each provided with a screw hole to connect with the first and

second bodies

10 and 20, respectively, through the screw hole.

Preferably, a notch 11 is formed in one side of the protective cover 1, and at least one of a first edge 111 and a second edge 112 forming the notch is connected with a lap joint part; the overlapping part can be folded over so that the gap 11 is completely covered. For example, as shown in fig. 3, a first overlapping part 12 and a second overlapping part 13 are respectively connected to two edges forming the notch 11; the first overlapping part 12 and the second overlapping part 13 can be folded over so that the notch 11 is completely covered. Alternatively, the first overlapping part 12 is connected only to the first edge 111, or the second overlapping part 13 is connected only to the second edge 112, as long as the first overlapping part 12 or the second overlapping part 13 can completely cover the notch. The arrangement of the notch enables the protective cover to be sleeved around the coupler of the reconnection after the first vehicle body and the second vehicle body are reconnected, and then the notch is completely covered by the lap joint part. The overlapping part can be covered by a zipper, a binding belt and the like.
