The body 1 is directly connected to the end wall of the vehicle body at the axial end position of the through passage 100.

In the following, in order to simplify the description, "the frame 1 and the docking member 2 are butted at the axial end of the through channel 100, and the frame 1 is a bellows frame, and the docking member 2 is an end wall frame" as an example. After reading the following technical solutions, the technician can obviously understand that the frame 1 and the docking member 2 are other technical solutions.

For example, in the specific example shown in FIGS. 1 and 2, the through passage 100 may include: an outer bellows D and an inner bellows E, the inner bellows E is inside the outer bellows D, and the outer bellows D and the inner bellows E At least one of them realizes connection and decompilation through the connection and decompilation mechanism 3 according to the embodiment of the present application.

In the specific examples shown in Figures 2 and 3, the outer bellows D may include: outer bellows body and outer bellows frame, the outer bellows frame includes: outer bellows bellows frame and outer bellows end wall frame, The outer bellows frame is connected to the shaft end of the outer bellows body (for example, it is connected into a whole by a cloth-clamped aluminum frame), the outer bellows end wall frame is installed on the end wall of the car body, the outer bellows end wall frame and the outer bellows The bellows frame is connected and unwrapped by the linking and unknitting mechanism 3.

At this time, the inner foldable shed frame can be used as the frame body 1, and the inner foldable shed end wall frame can be used as the butting piece 2.

It is understandable that, according to the embodiments of the present application, the inner bellows body and the outer bellows body can be clamped by a plurality of V-shaped structure of the cloth and the cloth sandwiched aluminum frame (it should be noted that for the field For the skilled person, the specific clamping method of the V-shaped structure of the shed cloth and the cloth-clamped aluminum frame is well known to those skilled in the art, so it will not be repeated.) The central frame A of the outer folding shed D is not used for docking and can only include a middle Frame D1. As shown in FIG. 2, the outer bellows D and the inner bellows E are connected by an inner connecting piece J into a whole. In addition, the top of the outer folding shed D can be provided with detachable lifting ears 11, and the lifting ears 11 can be disassembled after the assembly is completed to ensure the appearance of the outer folding shed D.

Of course, the present application is not limited to this, and the through passage 100 according to other embodiments of the present application may also include only the outer bellows D, but not the inner bellows E. Moreover, when the through passage 100 includes both the outer bellows D and the inner bellows E, only one of the inner bellows E and the outer bellows D may pass through the continuous hanging and unraveling mechanism according to the embodiment of the present application. 3 Realize the connection and decompilation, while the other does not realize the connection and decompilation through the connection and decompilation mechanism 3 according to the embodiment of the present application.

As shown in Figs. 3 and 4, the linking and dismantling mechanism 3 may include: a pressing mechanism 32, a manipulation mechanism 33, and a cable 34. The pressing mechanism 32 is provided on the docking member 2 and includes a rotating pressing block 321, a rotating pressing block 321 During the rotation, it can reach the locked position (as shown in FIG. 5) that is press-fitted with the frame 1 and the unlocked position (as shown in FIG. 6) that is disengaged from the frame 1 (as shown in FIG. 6). The operating mechanism 33 is provided in the docking member 2 and The rotating pressure block 321 is pulled by the cable 34 to rotate.

In addition, when the continuous-hanging disassembly mechanism 3 is provided at the shaft end of the through channel 100, an inspection opening can be opened on the interior end wall panel, and an inspection hole can be opened on the car body end wall to realize the control mechanism 33 Operation, to further prevent the continuous hanging and unmarching mechanism 3 from being exposed inside the inner bellows E.

In some embodiments of the present application, as shown in FIG. 3, the cable 34 may include a first cable c1. The first cable c1 has a closed loop shape and is connected to a manipulation mechanism 33. As described herein, the "ring" It is not limited to a circular ring, such as a polygonal ring. Therefore, the first cable c1 can be used in the connection and unmarching of the outer bellows D, and for the “multiple cables 34 cooperate with the multiple operating mechanisms 33 to realize the continuous hanging and unmarching” described later. , It can reduce the material usage of the cable 34 and the operating mechanism 33 in the connecting and disassembling mechanism 3, reduce the cost, and simplify the operation.

For example, as shown in FIG. 3, the through passage 100 includes (orthogonally projected) a closed annular outer bellows D, and the rotating pressing block 321 includes a plurality of first rotating pressing blocks b1 distributed along the circumferential direction of the outer bellows D. The cable c1 passes through the plurality of first rotating pressing blocks b1 sequentially to pull the plurality of first rotating pressing blocks b1 to rotate synchronously. As a result, only by operating one operating mechanism 33 to pull one first cable c1, the outer bellows D can be connected or disassembled simply and effectively, with simple operation and quick action.

In some embodiments of the present application, as shown in FIG. 4, the cable 34 may include a second cable c2. The second cable c2 has an open ring shape and the two ends of the opening are respectively connected to a manipulation mechanism 33. Therefore, the second cable c2 can be used in the connection and unmarshalling of the inner bellows E, and for the following "multiple cables 34 cooperate with a plurality of operating mechanisms 33 to realize the continuous hanging and unmarshalling" , It can reduce the material usage of the cable 34 and the operating mechanism 33 in the connecting and disassembling mechanism 3, reduce the cost, and simplify the operation.

The cable c2 sequentially passes through the plurality of second rotating pressing blocks b2 to pull the plurality of second rotating pressing blocks b2 to rotate synchronously. Therefore, by operating the two manipulation mechanisms 33 to pull one second cable c2, the inner bellows E can be connected or unwrapped simply and effectively, with simple operation and quick action.

Of course, the present application is not limited to this. In other embodiments of the present application, for the connection and disassembly of the outer bellows D, it can also be realized by multiple cables 34 cooperating with multiple operating mechanisms 33. Similarly, for the inner As for the continuous hanging and disassembly of the bellows E, it can also be realized by multiple cables 34 cooperating with multiple operating mechanisms 33, which will not be repeated here.

In some embodiments of the present application, as shown in FIGS. 3 and 4, the docking member 2 may also have a pulley 36, and the cable 34 is wound around the pulley 36, so as to improve the smoothness of the cable 34 and improve the connection. Hang up the problem of motion jamming of the editing mechanism 3. Moreover, by arranging the pulley 36 at the corner of the docking member 2, the pulley 36 can also be used to change the direction of movement of the cable 34 while improving the smoothness. It should be noted that each corner of the docking member 2 can be separately provided. A plurality of pulleys 36, such as two or three, are provided, so that the angle at which each pulley 36 changes the direction of movement of the cable 34 is not too large, thereby further improving the smoothness.

For example, in the example shown in FIG. 3, a plurality of pulleys 36 may be distributed at intervals in the circumferential direction of the outer bellows D, and the first cable c1 may be wound on the plurality of pulleys 36 in sequence, thereby increasing the first cable c1. The smoothness of being pulled avoids the problem of jamming of the first cable c1 and can reduce the wear of the first cable c1. For another example, in the example shown in FIG. 4, a plurality of pulleys 36 may be distributed at intervals in the circumferential direction of the inner bellows E, and the second cable c2 may be wound on the plurality of pulleys 36 in sequence, so as to increase the second cable The smoothness of c2 being pulled can avoid the problem of jamming of the second cable c2 and reduce the wear of the second cable c2.

As shown in FIGS. 7 and 8, in a specific example of the present application, the pressing mechanism 32 may include a base 322, a rotating shaft 323, and a circlip 324. The base 322 is fixedly mounted on the docking member 2, and the rotating pressing block 321 passes through The axial position of the rotating pressing block 321 relative to the rotating shaft 323 is defined on the rotating shaft 323 and by the circlip 324. The rotating pressing block 321 is rotatable relative to the base 322 via the rotating shaft 323, that is, the rotating pressing block 321 can be fixed around the base 322 The rotating shaft 323 on the docking member 2 rotates. Therefore, the rotation of the rotating pressing block 321 can be simply and effectively realized, the structure is simple, and the processing and assembly are convenient.

In some embodiments of the present application, as shown in FIGS. 7 and 8, each rotating pressing block 321 may include a first pressing cover 3211 and a second pressing cover 3212 that are detachably connected, and the cable 34 is pressed by the first

pressing cover

3211 and 3212. The cover 3211 and the second pressing cover 3212 pass through, and are connected to the first pressing cover 3211 through the first connecting member 35. Therefore, the connection between the rotating pressing block 321 and the cable 34 can be realized simply and effectively, so that the cable 34 can pull the rotating pressing block 321 to rotate. It should be noted that the orientation of the first pressing cover 3211 and the second pressing cover 3212 is not limited, that is to say, during assembly, the first pressing cover 3211 can be disposed on a side of the second pressing cover 3212 close to the frame 1. On the other hand, the second pressing cover 3212 may also be provided on the side of the first pressing cover 3211 close to the frame 1.

In some specific examples of the present application, as shown in FIG. 7, the first connecting member 35 may be a cable pin rotatably connected with the first pressing cover 3211, that is, the first pressing cover 3211 may have a pin hole, The cable pin is rotatably inserted into the pin hole, and the cable pin is fixed on the cable 34, so that the cable 34 can rotate relative to the first gland 3211 and the second gland 3212, thereby reducing the bending of the cable 34. Folding and abrasion can increase the service life of the cable 34.

In addition, it should be noted that the detachable connection manner of the first gland 3211 and the second gland 3212 is not limited. For example, in some specific examples, threaded connections (such as bolts, screws, etc.) can be used as shown in FIG. 8 The first position 32a and the second position 32 shown connect the first pressing cover 3211 and the second pressing cover 3212. For example, in other embodiments of the present application, the first pressing cover 3211 and the second pressing cover 3211 may also be connected The second gland 3212 can be detachably connected.

In some specific examples of the present application, as shown in FIG. 8, a groove 31 may be formed on the frame 1, and when the rotating pressing block 321 is rotated to the locked position (as shown in FIG. 5), the rotating pressing block 321 is pressed against On the groove 31. In other words, the size of the groove 31 is adapted to the movement track of the rotating pressing block 321, and the rotating pressing block 321 is rotated to compress and loosen the frame body 1. For example, in the example shown in FIGS. 3 and 4, the groove 31 may include a first groove a1, which is adapted to cooperate with the first rotary pressing block b1, and a second groove, which is adapted to cooperate with the second rotary pressing block b2.槽a2.

5 and 6, thus, the side wall 311 of the groove 31 can be used to limit the rotation of the rotating pressing block 321, so that the rotating pressing block 321 stays in the locked position to prevent the rotating pressing block 321 from rotating beyond the locked position (For example, avoid the rotating pressing block 321 shown in FIG. 5 and continue to rotate clockwise). Thus, the reliability of the connection can be improved and the probability of misoperation can be reduced. Of course, the present application is not limited to this. The frame 1 may not have the groove 31. At this time, in order to realize the rotation limit, the frame 1 may also be provided with a limiting rib or a limiting clamping hole, etc., which is not used here. Repeat.
