[0019] In one of the embodiments, the shell is filled with protective gas, and the internal air pressure of the shell is greater than the external air pressure of the shell.
[0020] In this way, the door body is better abutted against the inside of the shell because the door body is arranged in the shell and the internal air pressure of the shell is greater than the external air pressure of the shell.

[0039] Referring to Figures 1-6 The utility model discloses an automatic man -machine interaction switch door system, including shell 10, door body 20, at least two transmission structure 40, power source structure 60 and guide structure 50, be provided with inclined plane 11 on shell 10, be provided with interactive mouth 111 on inclined plane 11;Door body 20 is located in shell 10 and covers interactive mouth 111;Each transmission structure 40 includes reciprocating motion assembly 41, reciprocating motion assembly 41 is parallel to ground and is connected with door body 20 movably;Power source structure 60 drives and connects all transmission structure 40;Guide structure 50 includes guide 52 and guide rail 51, guide 52 is movably connected with door body 20 and is slidably connected with guide rail 51, and guide rail 51 is obliquely arranged on the downside of reciprocating motion assembly and there is the included angle α between reciprocating motion assembly 41.
[0040] It can be understood that by adding inclined plane 11 to shell 10 and setting interactive mouth 111 on inclined plane 11, the man-machine interaction sense is good, wherein the reciprocating motion assembly 41 is used for opening and closing door body 20 while cooperating with guide 52 moving on guide rail 51 to realize small door opening amplitude, the reciprocating motion assembly 41 is parallel to ground, there is the included angle α between guide rail 51 and reciprocating motion assembly 41, so that the opening track of door body 20 is moved along guide rail 51 while the door body 20 itself rotates by a certain angle, thereby avoiding the problem of collision with other structures in the inside of shell 10.
[0041] In combination Figures 1-6As shown, each reciprocating motion component includes a reciprocating screw 411 and a screw block 412. The screw block 412 is threadedly engaged with the reciprocating screw 411 and is movably connected to the door body 20. The reciprocating screw 411 is rotatably connected inside the housing 10. The angle between the reciprocating screw 411 and the guide rail 51 is angle α.
[0042] Understandably, this design uses two reciprocating lead screws 411 to drive two rod blocks, further reducing structural complexity, facilitating maintenance, and improving the coordination of door 20 opening and closing. This design also incorporates two guide members 52 and two guide rails 51, resulting in more coordinated and smoother movement of door 20. All moving connections are hinged joints with shaft-hole fits.
[0043] Combination Figures 1-6 As shown, a support structure 30 is provided inside the outer casing 10. The support structure 30 includes a first fixing member 31, a second fixing member 32, and a connecting member 33. The second fixing member 32 of the first fixing member 31 is fixedly connected inside the outer casing 10. One end of the connecting member 33 is fixedly connected to the first fixing member 31, and the other end is fixedly connected to the second fixing member 32. All reciprocating screws 411 are rotatably connected to the connecting member 33, and all guide rails 51 are fixedly connected between the first fixing member 31 and the second fixing member 32.
[0044] Understandably, the support provided by the first fastener 31 and the second fastener 32 avoids the need for all structures to be mounted on the outer casing 10, thereby further improving airtightness.
[0045] Combination Figures 1-6 As shown, the power source structure 60 includes at least two connecting wheels 61, a transmission wheel 62, a drive motor, and a transmission belt 63. All connecting wheels 61 are fixedly connected to each reciprocating lead screw 411. The transmission wheel 62 is rotatably connected to the connecting member 33. The transmission belt 63 connects all connecting wheels 61 and the transmission wheel 62. The drive motor is poweredly connected to one of the connecting wheels 61 and is fixedly connected inside the housing 10.
[0046] Understandably, by using two connecting wheels 61 to connect the two reciprocating lead screws respectively, and cooperating with the transmission wheel 62 for transmission, the movement can be synchronized, further controlling the coordination of the door body 20's movement.
[0047] Combination Figures 1-6 As shown, the power source structure 60 also includes an adjustment component 70, which includes a movable component 71. The connecting component 33 has a fixed groove 331 on the side facing away from the transmission wheel 62. One of the groove walls of the fixed groove 331 has a through opening 332. The movable component 71 is fixedly connected to the fixed groove 331 by passing through the other groove wall of the fixed groove 331 with screws. The transmission wheel 62 is rotatably connected to the movable component 71 by a connecting shaft, which passes through the through opening 332.
[0048] Understandably, by using the fixed groove 331 to adjust the position of the moving part 71, the position of the transmission wheel 62 is controlled to control the tension of the transmission belt 63, thereby facilitating the maintenance of the transmission position.
[0049] Combination Figures 1-6 As shown, a loading platform 12 is movable inside the outer casing 10. The loading platform 12 is located between the first fixing member 31 and the second fixing member 32, and is located below the connecting member 33. It can extend out of the interaction port 111. A sealing strip 21 is fixedly installed around the interaction port 111. The sealing strip 21 abuts against the door body 20. The inner side of the sealing strip 21 seals the interaction port 111. The connection point between the door body 20 and the guide member 52 and the lead screw block 412 is located outside the sealing strip 21.
[0050] Understandably, sealing the door 20 with the interface 111 by the sealing strip 21 avoids the problem of protective gas leakage, and the sealing strip 21 also blocks the connection between the door 20 and other parts from the outside, further improving the sealing performance.
[0051] Combination Figures 1-6 As shown, the outer casing 10 is filled with protective gas, and the gas pressure inside the outer casing 10 is greater than the gas pressure outside the outer casing 10.
[0052] It is understandable that because the door 20 is located inside the outer casing 10, and the air pressure inside the outer casing 10 is greater than the air pressure outside the outer casing 10, the door 20 can be better pressed against the inside of the outer casing 10.
[0053] The working principle of this automatic human-machine interactive door opening and closing system is as follows: When the drive motor is started, one of the connecting wheels 61 rotates, driving the transmission belt 63 to rotate the transmission wheel 62, which in turn drives all the remaining connecting wheels 61. This causes the two reciprocating screws 411 to rotate synchronously, and the two screw blocks 412 to rotate synchronously, pulling the door body 20 to move. The guide rail 51 restricts the door body's movement trajectory. The door body 20 drives the two guide members 52 to move. When the door body 20 is closed, the angle between it and the guide rail 51 is acute. During the movement, the door body 20 first rotates a certain angle around the guide member 52 as the center of rotation, and then gradually moves towards the guide rail 51. 1. When fully open, the angle between the parallel and guide rail 51 is obtuse. At this point, human-machine interaction is performed. The loading platform 12 extends out of the interaction port 111. When closing is required, the drive motor is started. One of the connecting wheels 61 rotates, driving the transmission belt 63 to drive the transmission wheel 62 to rotate, which in turn drives all the remaining connecting wheels 61. As a result, the two reciprocating screws 411 start to rotate synchronously, and the two screw blocks 412 rotate synchronously, pulling the door body 20 to move. The guide rail 51 restricts the movement trajectory of the door body 20. The door body 20 drives the two guides 52 to move until the door body 20 is closed, and the sealing strip 21 abuts against the outer shell 10.
[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0055] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
