For specific reference, see Figure 5 and Figure 6 , the plug-in connection frame 32 includes two symmetrically arranged first connecting members 321 and a second connecting member 322. The first connecting member 321 is arranged close to the vehicle body, and the second connecting member 322 is arranged close to the door body 1. A part of the first connecting member 321 is located in the receiving space and is rotatably connected to the second fixing member 312 through a second pivot shaft 324, and a part is located inside the second connecting member 322. The first connecting member 321 and the second connecting member 322 are rotatably connected through a plurality of first pivot shafts 323 to form a rotating connection part. One side of the second connecting member 322 close to the door body 1 is fixedly connected to the slider, and the slider is slidably connected to the slide rail on the door body 1. It should be noted that the end of the first connecting member 321 close to the vehicle body is the first end of the plug-in connection frame 32 close to the vehicle body, and the end of the second connecting member 322 close to the door body 1 is the second end of the plug-in connection frame 32 close to the door body 1.

[0058] As Figure 4 and Figure 6 shown, the first plug-in guide 33 is fixedly connected to the fixed mounting member 36 through fasteners such as screws, and the fixed mounting member 36 is fixedly connected to the one located at Figure 6On the second fixing member 312 in the upper middle. Specifically, a sela guide groove is provided on the first sela guide member 33. The sela guide groove includes a locking groove 331 and an arc-shaped guide groove 332 that are connected.

Among them, the movement of the first end of the swing acting member 34 on the door body 1, and the movement of the second end of the swing acting member 34 in the sela guide groove are coordinated to realize the sela movement of the door body 1.

[0059] In this embodiment, the swing acting member 34 is rotatably arranged on the connecting member. Specifically, refer to Figure 6 , where one first pivot shaft 323 rotatably connects the swing acting member 34, the first connecting member 321 and the second connecting member 322. A first guide wheel 341 is provided on the first end of the swing acting member 34. The first guide wheel 341 is arranged on the side of the swing acting member 34 away from the sela guide groove and always abuts against the door body 1; a second guide wheel 342 is provided on the second end of the swing acting member 34. The second guide wheel 342 is arranged on the side of the swing acting member 34 close to the sela guide groove and is located in the sela guide groove. With such an arrangement, the first guide wheel 341 and the second guide wheel 342 are located on different sides, avoiding the situation of mutual interference between the first guide wheel 341 and the first sela guide member 33 during the movement process.

[0060] When the door body 1 is opened, the sela connecting frame 32 gradually opens. The first end of the swing acting member 34 changes from the clamped state of being clamped in the blocking groove 11 to the sliding state of abutting against the door body 1. The second end of the swing acting member 34 moves in the sela guide groove in the direction close to the vehicle body and is locked in the sela guide groove, that is, the second end of the swing acting member 34 enters the locking groove 331 from the arc-shaped guide groove 332 for locking, and the door body 1 is pulled out from the doorway. Among them, as Figure 9 shown, it shows the cooperation relationship between the first sela guiding device 3 and the door body 1 when the door body 1 is opened in place; when the door body 1 is closed, the sela connecting frame 32 gradually closes.

By providing a plurality of second plug guide devices 4, the second plug guide devices 4 assist the plug movement at other positions of the door body 1, for example, they can be arranged at the lower part of the door body 1, so as to avoid the shaking and other unstable movements when the door body 1 is opened and closed as much as possible.

[0064] The swinging member is rotatably connected to the vehicle body; the second plugging guide member 42 is arranged on the door body 1; the plugging action member is arranged on the plugging swinging member 41 and moves along the second plugging guide member 42. Specifically, the plugging action member includes a plurality of plugging guide wheels 43, and the plugging guide wheels 43 clamp the plugging wall surface of the second plugging guide member 42; the limit stopper 44 is arranged on the plugging swinging member 41, and when the door body 1 is closed, the limit stopper 44 and the plugging guide wheel 43 located in the matching guide groove 421 are both in contact with the matching guide groove 421; the matching stopper 45 is arranged on the plugging swinging member 41 and cooperates with the stopping transmission device 5, and the matching stopper 45 can be set to a prismatic structure, such as Figure 13As shown, when the stop transmission device 5 is located on the movement track of the mating stop 45 under the action of the pushing member 35 and abuts against the limit stop 44, the stop transmission device 5 is in a blocking state at this time, and as Figure 14 shown, when the stop transmission device avoids the movement track of the mating stop 45, the stop transmission device 5 is in an avoidance state at this time.

[0065] By providing the limit stop 44, when the door body 1 is closed, the limit stop 44 and the plug guide wheel 43 together position the second plug guide 42 to prevent the door body 1 from shaking under the action of an external force when it is closed.

[0066] As Figure 12 shown, the plug wall surface in this embodiment includes a plug arc surface and a plug flat surface 462 arranged in sequence along the direction away from the vehicle body. The plug arc surface protrudes arc-shaped in the direction away from the door body 1, and the plug flat surface 462 is tangent to the plug arc surface.

[0067] As Figure 13 shown, the number of plug guide wheels 43 can be set to three. Two plug guide wheels 43 are located outside the plug wall surface, and one plug guide wheel 43 is located in the mating guide groove 421 inside the second plug guide 42. As shown in Figure 15 shown, when the door body 1 is closed, the positional relationship among the three plug guide wheels 43, the mating stop 45, the mating guide groove 421 and the second acting member 57 is shown; and as shown in Figure 16 shown, when the door body 1 is opened, the positional relationship among the three plug guide wheels 43, the mating stop 45, the mating guide groove 421 and the second acting member 57 is shown.

[0068] As Figure 10 and Figure 11 shown, the stop transmission device 5 in this embodiment includes a stop transmission mounting member 51, a transmission rod 52, a reset mounting member 53, a transmission reset member 54, a stop transmission limiting member 55, a first acting member 56 and a second acting member 57. Specifically, there are two stop transmission mounting members 51, both of which are fixedly arranged on the vehicle body. Of course, one or three or more than three stop transmission mounting members 51 can also be provided; the transmission rod 52, which is separately arranged or integrally arranged, passes through the stop transmission mounting member 51; the reset mounting member 53 is sleeved and fixed on the transmission rod 52; one end of the transmission reset member 54 is fixedly arranged on the stop transmission mounting member 51 located in the upper middle of Figure 1 and the other end is fixedly arranged on the reset mounting member 53; the stop transmission limiting member 55 is arranged on the one located in Figure 1On the upper and middle stop transmission mounting member 51 and protruding from the lower wall surface of the reset mounting member 53 is provided to limit the reset mounting member 53; the first acting member 56 and the second acting member 57 are respectively arranged at the upper and lower ends of the transmission rod 52, wherein the first acting member 56 cooperates with the pushing member 35, and a blocking guide wheel 58 that cooperates with the cooperating blocking member 45 is provided on the second acting member 57.

[0069] When the door body 1 is closed, the pushing member 35 acts on the first acting member 56, and the first acting member 56 drives the transmission rod 52 to rotate to drive the second acting member 57 to rotate, so that the blocking guide wheel 58 located on the second acting member 57 rotates from the avoidance state to the blocking state to block the movement of the first plug guide device 3 and the second plug guide device 4. Even when the door body 1 is impacted by an external force, the stop transmission device 5 blocks the movement of the second plug guide device 4 to ensure performance such as the sealing performance and safety when the door body 1 is closed; when the door body 1 is opened, the transmission reset member 54 drives the transmission rod 52 to rotate to drive the second acting member 57 to rotate until the blocking guide wheel 58 changes from the blocking state to the avoidance state, thereby ensuring the normal operation of the opening and closing of the door body 1.

[0070] For a plug door of the present invention, when the door body 1 is opened, during the process of the driving transmission device 2 driving the door body 1 to open, the first plug guide device 3 and the second plug guide device 4 perform a plug movement with the same plug movement trajectory, so that the door body 1 is pulled out from the doorway to open. At this time, the stop transmission device 5 is in the avoidance state; when the door body 1 is closed, during the process of the driving transmission device 2 driving the door body 1 to close, the first plug guide device 3 and the second plug guide device 4 perform a plug movement with the same plug movement trajectory, so that the door body 1 is inserted into the doorway to close. When the door body 1 is closed in place, the stop transmission device 5 is in the blocking state.

[0071] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
