[0032] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0033] Reference Figure 1 to Figure 7The present embodiment provides a trigger module of a head hood opening device of an EMU, comprising a substrate 1, a linear drive 2 is mounted on the upper surface of the substrate 1, and a lock pin 21 is mounted on the output shaft of the linear drive 2. The housing of the linear drive 2 is fixedly connected to the substrate 1 by bolts, and the output shaft of the linear drive 2 is fixedly connected to the lock pin 21 by bolts, and the linear drive 2 can drive the lock pin 21 to reciprocate linearly along the axial direction. The axis of the lock pin 21 is arranged parallel to the axis of the output shaft of the linear drive 2; a connecting wing plate 3 is arranged upright on the side of the substrate 1, and the connecting wing plate 3 is arranged perpendicular to the substrate 1. The connecting wing plate 3 is provided with a first plug hole 31 adapted to the lock pin 21, and the first plug hole 31 is arranged coaxially with the lock pin 21. Among them, the base plate 1 is fixedly connected to the mounting frame of the EMU head cover by bolts, and the connecting wing plate 3 is fixedly connected to the EMU head cover by bolts; when the locking pin 21 is inserted into the first plug hole 31, the locking pin 21 can limit the movement of the connecting wing plate 3 and the EMU head cover, thereby locking the EMU head cover; when the locking pin 21 is pulled out from the first plug hole 31, the locking of the locking pin 21 and the connecting wing plate 3 fails, and the EMU head cover can slide open when subjected to thrust.

[0034] Reference Figure 1-2 The side wall of the connecting wing plate 3 is detachably mounted with a trigger assembly 4; the trigger assembly 4 is used to push the lock pin 21 out of the first plug hole 31 when the linear drive 2 fails. The trigger assembly 4 and the linear drive 2 are arranged on both sides of the connecting wing plate 3 to avoid spatial conflict between the trigger assembly 4 and the linear drive 2, so that the user can operate the trigger assembly 4 easily.

[0035] Reference Figure 2 to Figure 5 The trigger assembly 4 includes a positioning plate 41; the side wall of the connecting wing plate 3 is fixedly mounted with a mounting protrusion 32, and there are four mounting protrusions 32 arranged in an inverted trapezoidal shape. The positioning plate 41 is provided with a card slot 412 adapted to the mounting protrusion 32, so that the user can press the positioning plate 41 downward onto the mounting protrusion 32, or pull the positioning plate 41 upward. The cross section of the mounting protrusion 32 is in the shape of a convex letter; the mounting protrusion 32 includes two cylinders of different diameters and coaxially fixedly connected (for example, by an integrated fixed connection), and the mounting protrusion 32 is fixedly connected to the connecting wing plate 3 by bolts. The cylinder with a larger diameter and the connecting wing plate 3 are arranged on the left and right sides of the cylinder with a smaller diameter, and the end face of the cylinder with a smaller diameter is crimped onto the connecting wing plate 3. The thickness of the positioning plate 41 is not greater than the height of the cylinder with a smaller diameter. After the positioning plate 41 is snapped onto the mounting protrusion 32, the cylinder with a larger diameter and the connecting wing plate 3 are arranged on the left and right sides of the positioning plate 41, thereby achieving a snap-on effect and preventing the positioning plate 41 from falling off.

[0036] Reference Figure 2 , Figure 6-7The trigger assembly 4 also includes a push column 42, a cushion block 43, a first transmission rod 44, and a second transmission rod 45; the positioning plate 41 is provided with a second plug hole 411, and the push column 42 is plugged into the second plug hole 411; the cushion block 43 is fixedly connected to the side wall of the positioning plate 41 (for example, fixedly connected by bolts), the end of the first transmission rod 44 is rotatably connected to the cushion block 43 (for example, hinged by a rotating shaft), one end of the second transmission rod 45 is rotatably connected to the middle part of the first transmission rod 44 (for example, hinged by a rotating shaft), and the other end of the second transmission rod 45 is rotatably connected to the push column 42 (for example, hinged by a rotating shaft).

[0037] Reference Figure 6-7 , the second plug hole 411 is adapted to the first plug hole 31 ; when the positioning plate 41 is snapped onto the mounting protrusion 32 , the second plug hole 411 is coaxially arranged with the first plug hole 31 .

[0038] Reference Figure 6-7 The cushion block 43 is located below the second plug hole 411. Therefore, when in use, the user flips the first transmission rod 44 upward, which has a larger operating space than flipping it downward, thereby improving the convenience of operation.

[0039] Reference Figure 2 , Figure 6-7 Two first transmission rods 44 are provided and are respectively arranged on the left and right sides of the push column 42, and two second transmission rods 45 are provided and are respectively arranged on the left and right sides of the push column 42. The first transmission rod 44 and the second transmission rod 45 located on the same side are connected to each other to ensure uniform force transmission, avoid unbalanced loading, improve the structural stability of the utility model, and increase the service life.

[0040] Reference Figure 2 The ends of the two first transmission rods 44 away from the push column 42 are fixedly connected by a cross brace (for example, by an integrated fixed connection or by a bolt fixed connection), and a gripping handle 46 is vertically fixedly connected to the middle of the cross brace. The gripping handle 46 is fixedly connected to the cross brace in a T-shape by bolts, and the end surface of the gripping handle 46 away from the push column 42 is provided with friction lines. When a user grips the friction lines, the friction between the gripping handle 46 and the gripping handle 46 can be increased to prevent the gripping handle 46 from slipping, thereby improving the safety of maintenance.

[0041] Reference Figure 2 , Figure 6-7 The two first transmission rods 44 are located at the same height and have the same length; the two second transmission rods 45 are located at the same height and have the same length; this allows the gripping rod to be flipped upwards, making it easier for users to operate.

[0042] Reference Figure 3 to Figure 5The opening of the card slot 412 is downward, and a guide structure is provided on the side wall at the opening position of the card slot 412; the guide structure, such as a chamfer or a rounded corner, can reduce the difficulty of installing the positioning plate 41 and increase the convenience of maintenance.

[0043] The linear drive 2 is an electric-controlled cylinder, which is connected to a gas tank and an electric control system.

[0044] Usage steps: ① The user unplugs the air supply pipe of the electric control cylinder; ② Install the trigger assembly 4 on the connecting wing plate 3, so that the mounting protrusion 32 is inserted into the card slot 412, and the first plug hole 31 is aligned with the second plug hole 411 (refer to Figure 6 ); ③ Grasp the gripping handle 46 away from one end of the positioning plate 41 and then flip it upwards, the second transmission rod 45 pushes the push column 42 to push the locking pin 21 out of the first plug-in hole 31, so that the connection between the locking pin 21 and the connecting wing plate 3 is invalid; ④ The user pushes / pries the EMU head cover to open the EMU head cover.

[0045] The utility model can use the trigger component 4 to push out the locking pin 21 in the first plug hole 31 when there is no electricity, and release the lock between the locking pin 21 and the connecting wing plate 3, so as to facilitate the subsequent opening of the EMU head cover. The utility model has a simple structure and is easy to operate. The trigger component 4 can be detachably installed on the side wall of the connecting wing plate 3. Therefore, during the normal driving of the EMU, the trigger component 4 can be placed in the maintenance tool box as an independent tool product, which will not have a negative impact on the connection between the locking pin 21 and the connecting wing plate 3. The storage is convenient, safe and reliable.
