The stator permanent magnet of the linear motor is fixed on the linear drive support beam 151 , and the rotor coil of the linear motor is fixed on the inner wall of the linear drive matching through hole 152 .

[0086] Embodiment 4:

[0087] Based on Example 3, Figure 4As shown, a support arm damping mechanism 34 is provided between the first door support arm 31 and the second door support arm 32, and the support arm damping mechanism 34 includes a hydraulic damping rod 341 connected between the first door support arm 31 and the second door support arm 32;

[0088] The hydraulic damping rod 341 is a hydraulic damping rod of the prior art;

[0089] A first support seat 3401 of a damping rod is fixed on the first door support arm 31, a second support seat 3402 of a damping rod is fixed on the second door support arm 32, an outer rod end of the hydraulic damping rod 341 is connected to the first support seat 3401 of the damping rod via an outer fixed hinge 342 of the damping rod, and an inner rod end of the hydraulic damping rod 341 is connected to the second support seat 3402 of the damping rod via an inner fixed hinge 343 of the damping rod.

[0090] In the actual application process of the present invention, the Figure 1 As shown in the figure, set the spatial coordinate system, the left and right direction is the x-axis, the up and down direction is the z-axis, and the vertical direction is perpendicular to the instruction manual. Figure 1 The direction of the plane is;

[0091] And attach a letter Figure 3 As shown, the upper side of the body 102 is set as the outer side, and the upper side of the body 102 is set as the inner side;

[0092] When the door 101 needs to be opened, the door 101 is pushed along the y-axis direction and toward the outside of the body 102, and the entire door 101 and the first door support arm 31 and the second door support arm 32 rotate around the first internal fixed hinge 301 and the body 102 and the second internal fixed hinge 302 respectively, so that the door 101 moves toward the outside of the body 102 as a whole;

[0093] During this process, the door guide rail connecting frame 33 rotates relative to the first door support arm 31 and the second door support arm 32 around the rotation axes of the first external fixed hinge 303 and the second external fixed hinge 304 respectively;

[0094] Under the joint restraint of the first door support arm 31 and the second door support arm 32, the door 101 extends out of the fuselage 102;

[0095] Then, the hatch door 101 is pushed along the x-axis direction, so that the hatch door 101 slides along the direction of the main support rail 12, and the hatch door 101 is away from the hatch opening of the fuselage 102, so as to facilitate the entry and exit of personnel and cargo;

[0096] Due to the deadweight of the hatch 101, a plurality of guide rail main support rollers 22 installed on the upper side of the guide rail main support slider 21 are rollingly supported on the main support guide rail 12, providing good support for the entire hatch 101;

[0097] The multiple guide rail main support rollers 22 installed on the upper and lower sides of the guide rail main support slider 21 are respectively rollingly supported on the two main support guide rails 12, which can provide better stability for the sliding movement of the cabin door 101;

[0098] During the sliding movement of the hatch 101, the multiple lateral restraint rollers 132 installed on the guide rail main support slider 21 are rollingly supported on the guide rail top pressure contact surface 1310 of the lateral restraint guide rail 131, and the lateral restraint mechanism 13 can provide a good lateral restraint effect for the hatch 101, that is, a restraint effect along the y-axis direction;

[0099] The damping constraint mechanism 14 can provide adaptive damping during the sliding of the cabin door 101, and provide a buffering effect during the sliding of the cabin door 101. During the sliding of the cabin door 101, the guide rail main support slider 21 moves relative to the axial direction of the damping constraint support shaft 141, and relative movement occurs between the strong magnetic column 142 and the damping constraint metal ring 143. The damping constraint metal ring 143 cuts the magnetic flux lines when moving in the magnetic field. According to Faraday's law of electromagnetic induction, when the magnetic field changes, an induced electromotive force will be generated in the conductor, namely the damping constraint metal ring 143. When the strong magnetic column 142 passes through the damping constraint metal ring 143, the magnetic field around the strong magnetic column 142 changes relative to the damping constraint metal ring 143, which will generate an induced electromotive force on the cross section of the damping constraint metal ring 143, and an induced current will be generated in the damping constraint metal ring 143.

[0100] When the magnetic field of the strong magnetic column 142 interacts with the magnetic field generated by the induced current of the damping constraining metal ring 143, an Ampere force opposite to the movement direction of the damping constraining metal ring 143 is generated, namely, the damping force. This Ampere force hinders the relative movement between the strong magnetic column 142 and the damping constraining metal ring 143, and the faster the relative movement between the strong magnetic column 142 and the damping constraining metal ring 143, the greater the damping force.

[0101] That is, it is possible to adaptively generate a damping force according to the sliding speed of the cabin door 101 to buffer the sliding motion of the cabin door 101;

[0102] The linear drive mechanism 15 provides automatic driving force for the sliding movement of the hatch 101. A linear motor structure of the prior art is arranged between the linear drive support beam 151 and the guide rail main support slider 21. The stator permanent magnet of the linear motor is fixed on the linear drive support beam 151, and the rotor coil of the linear motor is fixed on the inner wall of the linear drive matching through hole 152. The linear motor structure can drive the guide rail main support slider 21 to move along the linear drive support beam 151, thereby driving the entire hatch 101 to move along the main support guide rail 12, providing auxiliary power for the opening and closing of the hatch 101.

[0103] By adjusting the distance between the guide rail main support roller 22 installed on the upper side of the guide rail main support slider 21 and the guide rail main support roller 22 installed on the lower side, the multiple guide rail main support rollers 22 installed on the upper and lower sides of the guide rail main support slider 21 are closely fitted and rolled on the two main support rails 12, respectively, to avoid the large movement gap causing the cabin door 101 to generate vibration and abnormal sound during the sliding movement;

[0104] First, the roller adjustment shaft 234 is unlocked, and a return spring is provided between the unlocking drive ring column 244 and the inner end of the locking mechanism connection hole 240, and the unlocking drive ring column 244 is pushed along the axial direction of the locking support cylinder 241. Under the mutual constraint of the unlocking constraint inclined groove 2441 and the unlocking constraint slide column 2442, the unlocking drive ring column 244 drives the locking clamping slide column 242 to move along the locking block connecting slide groove 2410, and the multiple locking clamping slide columns 242 move away from each other, so that each locking clamping slide column 242 is separated from the locking block clamping matching groove 2430;

[0105] At this time, the roller adjustment shaft 234 can rotate freely around its axis;

[0106] The end of the roller adjustment shaft 234 has an inner hexagonal hole. The roller adjustment shaft 234 is driven to rotate by an inner hexagonal tool. Under the constraint of the roller adjustment eccentric cylinder 235 and the eccentric cylinder matching hole 2320, the roller adjustment shaft 234 can drive the roller support connecting plate 231 to move up and down along the roller adjustment connecting groove 230 through the roller adjustment support plate 232, thereby adjusting the distance between the guide rail main support rollers 22 installed on the upper and lower sides of the guide rail main support slider 21;

[0107] After the adjustment is completed, the unlocking drive ring column 244 is released, and the unlocking drive ring column 244 returns to the initial position under the drive of the reset spring, and finally each unlocking drive ring column 244 is re-engaged and constrained in the locking block engagement groove 2430, limiting the rotation of the roller adjustment shaft 234 around its axis.
