As a result, the first hook structure 100a has a simple structure, is easy to process, and is easy to operate, realizes the quick disassembly and assembly of the first frame 11 and the outer folding shed frame 3, and improves the disassembly and assembly efficiency of the through channel 100; The first lock member 31 is configured to include a first sub-lock member 31a and a second sub-lock member 31b with different structures, so that the structure of the through channel 100 is flexible, and the disassembly and assembly of the first sub-lock member 31a and the second sub-lock member 31b The required space can be different in order to better adapt to the disassembly and assembly of the through channel 100.

For example, in the examples of FIGS. 4 and 7-9, the first sub-locking member 31a may include a first lock section and two second lock sections, and the two second lock sections may be spaced apart in the horizontal direction, each The second lock segments all extend vertically in the up and down direction, and the first lock segment is connected to the upper ends of the two second lock segments, so that the first lock hole 311 defined by the first sub-locking member 31a can be formed as an open opening provided below. The hole further facilitates the quick assembly and detachment of the first lock member 31 and the first hook 13, and at the same time, the first lock member 31 has a simple structure, a small amount of materials, and a low cost. The second sub-locking member 31b may be roughly formed as a plate-like structure, and a part of the side of the second sub-locking member 31b facing the bellows frame 3 is spaced apart from the bellows frame 3, so that the first limiting portion 132 can be locked Set on the second sub-lock 31b.

Of course, the first sub-locking member 31a and the second sub-locking member 31b can also be formed in other structural forms, which are not limited to this; for example, the first sub-locking member 31a can also be formed in a square structure, in which case the first locking hole 311 It can be formed as an open hole closed all around.

It can be understood that when the first limiting portion 132 extends vertically upward from the first supporting portion 131, the first limiting portion 132 and the first supporting portion 131 may be perpendicular to each other; When a supporting portion 131 extends obliquely upward, the first restricting portion 132 may extend obliquely with respect to the vertical direction. At this time, the first restricting portion 132 may extend upward and toward the direction close to the first supporting portion 131, or A limiting portion 132 can also extend upward and toward a direction away from the first supporting portion 131, so that an acute or obtuse angle can be formed between the first limiting portion 132 and the first supporting portion 131.

Wherein, there may be one or more first hooking structures 100a; when there are multiple first hooking structures 100a, the plurality of first hooking structures 100a may be arranged in sequence along the extension direction of the first frame 11 to facilitate ensuring The force of the end wall frame 1 is balanced, so that the end wall frame 1 can be used reliably. At the same time, the first hook 13 of each first hook structure 100a can respectively define the first limit position with the opening upward together with the first frame body 11 The slot 130 makes the disassembly and assembly directions of the multiple first hook structures 100a the same, which further ensures the efficiency of coupling and unhooking.

For example, the first hook 13 may be welded to the first frame 11, but it is not limited to this. For example, the first hook 13 may also be integrally formed with the first frame 11.

For example, in the examples of Figures 9, 12 and 17, the first limiting portion 132 extends vertically upward from the first supporting portion 131, and the free end of the first limiting portion 132 may be formed in a diagonal wedge shape, that is, the The end surface of the free end of a limiting portion 132 is inclined with respect to the horizontal plane, and the end surface extends obliquely from top to bottom in the direction from the outer folding shed frame body 3 toward the first frame body 11, which further facilitates the rapid speed of the first lock 31 Hooking on the first hook 13 improves the efficiency of connecting.

According to some embodiments of the present application, as shown in Figs. 11, 12 and 17, the outer bellows frame 3 is formed with an escape groove 30 that is recessed toward the outer bellows body 2. The escape groove 30 can be moved from the outside The part of the surface of the bellows frame 3 facing the first frame 11 is recessed toward the direction away from the first frame 11, thereby improving the structural strength of the outer bellows frame 3 and ensuring the outer bellows frame 3. The reliability of use. The first lock member 31 is located in the avoidance groove 30, so that the through channel 100 has a compact structure, a small space occupation, and good applicability, and facilitates the sealing between the outer folding shed frame 3 and the car body end wall 101, and the first A lock 31 is detachably connected to the outer folding shed frame 3. At this time, the first lock 31 and the outer foldable shed frame 3 can be mutually independent parts. The first lock 31 and the outer foldable shed frame 3 can be Separate processing simplifies the structure of the first lock 31 and the outer bellows frame 3, facilitates the processing of the first lock 31 and the outer bellows frame 3, and at the same time facilitates the first lock 31 and the outer bellows frame Disassembly and assembly of body 3.

Wherein, the first lock member 31 can be fixedly connected to the outer bellows frame 3 by threaded connections such as bolts, screws, etc., to ensure the reliability of the connection between the first lock member 31 and the outer bellows frame 3; understandable However, the first locking member 31 and the outer bellows frame 3 can also be connected in other ways, but not limited to this.

In some embodiments, the first connecting member 100b is a threaded connecting member, but is not limited thereto. For example, the first connecting member 100b may be a bolt, a screw, or the like.

For example, as shown in Figures 11, 12 and 17, the outer bellows frame 3 is formed with a sealing groove 32 recessed in the direction of the outer bellows body 2. The sealing groove 32 can be formed from the outer bellows frame 3 facing Part of the surface of one side of the car body end wall 101 is recessed toward the direction away from the car body end wall 101, the sealing groove 32 is annular and the sealing groove 32 extends along the extension direction of the outer folding shed frame 3, and the sealing groove 32 is filled with Seals. When the through channel 100 is used for the train 200, the sealing member can seal the gap between the outer bellows frame 3 and the car body end wall 101 on the entire circumference of the channel 20 to realize the outer bellows frame 3 and the car body end wall. The effective sealing between 101 prevents water in the external environment from flowing into the cabin 1021 and causes water leakage in the cabin 1021, and at the same time avoids the airflow noise caused by the above-mentioned gaps, thereby improving the comfort of passengers.

For example, in the examples of FIGS. 11, 12, and 17, the cross-sectional shape of the sealing groove 32 may be approximately C-shaped, and a sealing groove 321 is formed on the side of the sealing groove 32 that faces away from the bellows body 2. On the cross section of the groove 32, the width L of the sealing groove 321 is smaller than the maximum width L _max of the sealing groove 32, so that the sealing groove 32 can play a good limiting role on the sealing element and ensure that the sealing element can reliably fit with the sealing groove 32 Inside.

In some embodiments of the present application, as shown in FIG. 1, FIG. 2, FIG. 5-7, FIG. 11 and FIG. 14, the hook assembly 100e includes a second hook structure 100c, and the bellows assembly 8 includes an outer bellows 81. The outer bellows 81 includes an outer bellows body 2 and an outer bellows frame 3.

The end of the inner roof folding shed 4 is fixedly connected with the upper part of the outer folding shed frame 3, and the end of the inner roof folding shed 4 is hooked and matched with the end wall frame 1 through the second hooking structure 100c, which facilitates the inner top folding The disassembly and assembly between the shed 4 and the end wall frame 1 improves the disassembly and assembly efficiency of the through channel 100.

Among them, "the end of the inner roof bellows 4" may refer to the end of the inner roof bellows 4 along the extension direction of the channel 20; "the upper part of the outer bellows frame 3" may refer to the end of the outer bellows frame 3 The part above the middle.

It is understandable that when the end of the inner roof bellows 4 and the end wall frame 1 are hooked and matched by the second hooking structure 100c, the outer bellows frame body 3 can be connected with the end wall frame 1 by the first hooking structure 100a. Hooking fit, or the outer folding shed frame 3 may not be hooked to the end wall frame 1.

For example, in the examples of FIGS. 2, 7 and 11, the hook assembly 100e may also include a first hook structure 100a, and the end wall frame 1 includes a first frame 11, a first frame 11 and an outer folding shed frame The bodies 3 are all formed in a ring shape, and the first frame body 11 and the outer bellows frame body 3 are hooked and matched by the first hooking structure 100a.

As a result, under the premise of ensuring that the through channel 100 is quickly connected and unhooked, the carrying capacity of the through channel 100 is improved, so that the through channel 100 is reliable in use and has good applicability.

In some embodiments, if the second frame body 12 is not connected to the first frame body 11, the second frame body 12 and the first frame body 11 are spaced apart, and the second frame body 12 and the first frame body 11 are independent of each other. Therefore, there is no direct or indirect connection relationship between the second frame body 12 and the first frame body 11, so that the connecting and unhooking of the through channel 100 is more flexible and the operation is convenient.

Of course, the second frame body 12 and the first frame body 11 can also be directly or indirectly connected, which improves the structural diversity of the through channel 100 and makes the design of the through channel 100 flexible.

In some embodiments, the second frame body 12 is a plurality of strips 120 and the plurality of strips 120 are spaced apart along the transverse direction of the through channel 100. Each strip 120 passes through the inner roof bellows 4 The two hooking structures 100c are hooked and matched. Therefore, under the premise of ensuring the reliable use of the through channel 100, the structure of the second frame 12 is simplified, the amount of materials used for the second frame 12 is saved, the cost is reduced, and the second frame 12 is better matched. The inner roof bellows 4 ensures that the inner roof bellows 4 is balanced in force. For example, as shown in Figure 1, Figure 2, Figure 6 and Figure 7, the inner roof bellows 4 may extend from one side of the bellows body 2 to the folding bed along the transverse direction of the through channel 100 (for example, the left and right direction in Figure 1). On the other side of the shed body 2, there can be two strips 120, the two strips 120 can be arranged horizontally and spaced along the extension direction of the inner roof bellows 4, and each strip 120 can be arranged along the inner roof. The extension direction of the bellows 4 extends horizontally; when the through-passage 100 is used by the train 200, each strip 120 is installed on the car body end wall 101 to realize the connection between the through-passage 100 and the carriage 1021.

It can be understood that the number of strips 120 may also be three or more; the arrangement of the plurality of strips 120 can be specifically set according to actual needs, and is not limited thereto.

Specifically, when the second hook 14 is hooked and fitted with the second locking member 41, the second limiting portion 142 can extend into the second locking hole 411, so that a part of the second locking member 41 is placed in the second limiting groove The inside of 140 is matched with the second limiting groove 140, so that the second hook 14 and the second frame body 12 can respectively limit the second lock member 41 to prevent the second lock member 41 from being in the extending direction of the channel 20 The large displacement relative to the second hook 14 causes the second lock member 41 to disengage from the second hook 14, and the second support portion 141 can support the second lock member 41 to prevent the second lock member 41 from moving up and down. It is easy to disengage from the second hook 14 in the direction, which ensures the reliability of the cooperation between the second hook 14 and the second lock member 41, and facilitates the quick completion of the hooking cooperation of the second hook 14 and the second lock member 41; When the hook 14 and the second lock member 41 need to be separated, the inner roof bellows 4 can be lifted up, and the second lock member 41 moves upward relative to the second hook 14 so that the second lock member 41 is separated from the second limiting slot 140 With cooperation, the second limiting portion 142 and the second locking hole 411 can be separated at this time, so that the second limiting portion 142 and the second locking member 41 can be separated, thereby quickly completing the second hook 14 and the second locking member 41 Split.
