[0028] Unless otherwise specified, in the claims and description, the terms “center,” “lateral,” “longitudinal,” “horizontal,” “vertical,” “top,” “bottom,” “inner,” “outer,” “upper,” “lower,” “front,” “rear,” “left,” “right,” etc., indicate the orientation or positional relationship based on the orientation and positional relationship shown in the drawings, and are only for the purpose of simplifying the description, and do not imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation.

[0029] like Figure 1 As shown, the aircraft door simulator of this application embodiment includes a cabin structure 100 and a moving mechanism 400. The cabin structure 100 is detachably disposed above the moving mechanism 400. The moving mechanism 400 can move along the ground to move the cabin structure 100 to the target position, thereby achieving the effect of flexible migration of the cabin structure 100.

[0030] In one embodiment, the cabin structure 100 and the moving mechanism 400 can be connected by screws.

[0031] In this embodiment, the cabin structure 100 and the mobile mechanism 400 are designed to be detachably connected. The cabin structure 100 can be transported to the target site independently without being installed on the mobile mechanism 400. After arriving at the site, the cabin structure 100 and the mobile mechanism 400 are assembled. This breaks through the limitations of the traditional "whole machine integrated transportation" mode, optimizes logistics arrangements and on-site operation processes, and is particularly suitable for remote, temporary or emergency deployment tasks.

[0032] like Figure 1As shown, the moving mechanism 400 includes a vehicle body 410 and a lifting assembly 430. The vehicle body 410 includes a frame 411 and wheels 412. The bottom of the lifting assembly 430 is mounted on the frame 411, and the top of the lifting assembly 430 is detachably connected to the cabin structure 100. The wheels 412 are rotatably connected to the frame 411 and are used to roll in contact with the ground to move the vehicle body 410. The lifting assembly 430 is used to drive the cabin structure 100 to rise and fall vertically to adapt to the door height of different aircraft models.

[0033] In one embodiment, the lifting assembly 430 is parallel to the first direction D1 in the lifting direction.

[0034] Optionally, a power source may be installed on the frame 411, which is connected to the drive wheel 412 to drive the drive wheel 412 to rotate. For example, the power source may include a motor.

[0035] Of course, in other embodiments, the frame 411 may not be equipped with a power source, and the vehicle body 410 may be moved by human power.

[0036] In one embodiment, the traveling wheel 412 is a caster wheel. By setting the traveling wheel 412 as a caster wheel, the operational flexibility and site adaptability of the mobile mechanism 400 can be improved.

[0037] In one exemplary embodiment, the lifting assembly 430 is a scissor lift.

[0038] Of course, in other embodiments, the lifting assembly 430 may also be a lifting mechanism comprising a plurality of vertically arranged hydraulic rods.

[0039] like Figure 1 As shown, the moving mechanism 400 also includes support legs 420, which are connected to the four corners of the frame 411. The support legs 420 have folding legs 421 and telescopic legs 422. One end of the folding leg 421 is rotatably pivotally connected to the frame 411 via a rotating mechanism. The folding leg 421 can be folded up or unfolded relative to the vehicle body 410. The telescopic leg 422 is connected to the other end of the folding leg 421 and can be extended or retracted.

[0040] When the moving mechanism 400 moves to the target position, the folding leg 421 is in an unfolded state relative to the vehicle body 410, and the telescopic leg 422 extends until the bottom of the telescopic leg 422 contacts the ground. At this time, the outrigger 420 can stably support the entire aircraft door simulator on the ground, reducing the risk of the cabin structure 100 overturning and improving operational safety.

[0041] When the mobile mechanism 400 moves, the telescopic leg 422 retracts, and the folding leg 421 is in a retracted state relative to the vehicle body 410. At this time, the outrigger 420 does not extend outward, which avoids the outrigger 420 from colliding with other equipment or personnel during the movement of the mobile mechanism 400, thus improving operational safety.

[0042] Of course, the position of the outriggers 420 is not limited to the four corners of the frame 411. For example, in other embodiments, the outriggers 420 may also be located on both sides of the frame 411 along the second direction D2 and / or on both sides of the third direction D3.

[0043] In one embodiment, the rotation axis of the rotating mechanism is parallel to the first direction D1. The rotating mechanism may include, but is not limited to, hinges, shafts, etc.

[0044] like Figure 2 As shown, the aircraft door simulator also includes pull rings 101 and anchoring ropes 102. Pull rings 101 are respectively installed at the four bases of the cabin structure 100. One end of the anchoring rope 102 is connected to the pull ring 101, and the other end is connected to an anchoring pit on the ground. The anchoring ropes 102 enhance the overall stability of the cabin structure 100, improve its wind resistance, and prevent the cabin structure 100 from overturning.

[0045] like Figure 3 As shown, the cabin structure 100 of this embodiment includes a frame 200 and an outer shell 300. The frame 200 is detachably connected to the top of the lifting assembly 430 of the moving mechanism 400, and the outer shell 300 covers at least a portion of the outer surface of the frame 200. The frame 200 includes a plurality of first frames 210 and a plurality of second frames 220. The plane of the first frames 210 is perpendicular to a first direction D1, and the plurality of first frames 210 are spaced apart along the first direction D1. The plane of the second frames 220 is perpendicular to a second direction D2, and the plurality of second frames 220 are spaced apart along the second direction D2. The first direction D1 is perpendicular to the second direction D2. Each first frame 210 is detachably connected to a plurality of second frames 220, and the outer shell 300 is detachably connected to at least one of the first frames 210 and the second frames 220.

[0046] In this embodiment, the cabin structure 100 has a detachable connection between the outer shell 300 and the frame 200, and a detachable connection between the first frame 210 and the second frame 220. This makes the cabin structure 100 a detachable assembly structure, allowing it to be disassembled into several individual, easily transportable modules. These modules facilitate manual handling and placement into standard transport containers, significantly improving the convenience of long-distance transportation and reducing transportation difficulty and cost. Furthermore, the frame 200 of the cabin structure 100 employs a cross-connection of multiple first frames 210 and second frames 220, giving the frame 200 excellent structural strength and deformation resistance, ensuring the safety of high-altitude operations. Therefore, the aircraft door simulator of this embodiment can achieve rapid deployment, flexible relocation, and efficient maintenance while ensuring structural safety and operational realism, adapting to diverse and high-frequency aviation training needs.

[0047] In one embodiment, the plurality of first frames 210 and the plurality of second frames 220 can be made of high-strength carbon steel structure, which gives the frame 200 excellent load-bearing capacity and resistance to deformation, thus ensuring the safety of high-altitude operations.

[0048] In one embodiment, the first frame 210 and the second frame 220 are detachably connected by bolts, eliminating the need for welding and enabling quick assembly and disassembly.

[0049] like Figure 3 As shown, the first frame 210 located at the bottom of the plurality of first frames 210 is defined as the bottom frame 210a, the first frame 210 located at the top is defined as the top frame 210b, and the first frame 210 located in the middle is defined as the middle frame 210c. The bottom frame 210a is detachably connected to the bottom of the plurality of second frames 220, the top frame 210b is detachably connected to the top of the plurality of second frames 220, and the middle frame 210c is detachably connected to the middle position of the plurality of second frames 220.

[0050] like Figure 4 As shown, the bottom frame 210a and the bottom of the multiple second frames 220 are respectively provided with a first positioning part 231. The first positioning part 231 is detachably and fastened to the bottom of the second frame 220 by fasteners.

[0051] By providing a first positioning part 231 on the bottom frame 210a, when assembling the bottom frame 210a and the multiple second frames 220, the workers can use the first positioning part 231 to quickly position the multiple second frames 220 relative to the bottom frame 210a, thereby improving assembly efficiency.

[0052] like Figure 4As shown, the bottom frame 210a is also provided with an auxiliary positioning part 232 adapted to the first positioning part 231. The auxiliary positioning part 232 is used to assist in aligning the first positioning part 231 with the second frame 220 when the bottom frame 210a and the second frame 220 are installed.

[0053] like Figure 4 As shown, the bottom frame 210a includes two first horizontal beams 211 and multiple first vertical beams 212. The first horizontal beams 211 extend along a second direction D2, and the two first horizontal beams 211 are spaced apart along a third direction D3. The multiple first vertical beams 212 are connected between the two first horizontal beams 211 and are spaced apart along the second direction D2. Among them, the two outermost first vertical beams 212 are connected end to end with the two first horizontal beams 211 to form a rectangular frame.

[0054] Each first vertical beam 212 is connected to at least one first positioning part 231, and each of the first horizontal beams 211 and the plurality of first vertical beams 212 is provided with an auxiliary positioning part 232. The first positioning part 231 is located on one side of the second frame 220 along the second direction D2 and is used to position and cooperate with the second frame 220 in the second direction D2. The auxiliary positioning part 232 is located on one side of the second frame 220 along the third direction D3 and is used to assist in positioning the second frame 220 in the third direction D3.

[0055] As an example, the first vertical beam 212 is provided with a first positioning part 231 on both sides along the second direction D2.

[0056] In one embodiment, each first vertical beam 212 is provided with at least two first positioning parts 231, and the at least two first positioning parts 231 are staggered. Taking a first vertical beam 212 with three first positioning parts 231 as an example, one first positioning part 231 is provided on one side of the first vertical beam 212 along the second direction D2, and the other two first positioning parts 231 are provided on the other side of the first vertical beam 212 along the second direction D2, and the three first positioning parts 231 are staggered in the second direction D2.

[0057] In an exemplary embodiment, both the first positioning part 231 and the auxiliary positioning part 232 are sheet-like structures. The first positioning part 231 and the auxiliary positioning part 232 are connected to the bottom frame 210a and extend out of the upper surface of the bottom frame 210a.

[0058] like Figure 5 As shown, the top frame 210b and the top of the plurality of second frames 220 are respectively provided with second positioning parts 243, and the second positioning parts 243 are detachably connected to the top of the second frame 220 by fasteners.

[0059] In one embodiment, the second positioning part 243 is a through hole, and the fastener passes through the through hole and is connected to the second frame 220.

[0060] like Figure 5 As shown, the top frame 210b has a first positioning piece 241 on each of the two outer corners near the outer shell 300, and an L-shaped second positioning piece 242 on each of the two outer corners away from the outer shell 300. The first positioning piece 241 and the second positioning piece 242 are both used to assist in the installation and positioning with the corresponding second frame 220.

[0061] By setting a first positioning piece 241 and a second positioning piece 242 on the top frame 210b, when assembling the top frame 210b with multiple second frames 220, the operator can quickly position the multiple second frames 220 relative to the top frame 210b with the help of the first positioning piece 241 and the second positioning piece 242, thereby improving assembly efficiency.

[0062] like Figure 5 As shown, the top frame 210b includes two second horizontal beams 213 and multiple second vertical beams 214. The second horizontal beams 213 extend along a second direction D2, and the two second horizontal beams 213 are spaced apart along a third direction D3. The multiple second vertical beams 214 are connected between the two second horizontal beams 213 and are spaced apart along the second direction D2. The two outermost second vertical beams 214 are sequentially connected to the two second horizontal beams 213 to form a rectangular frame. Each second vertical beam 214 is provided with a second positioning part 243.

[0063] In one embodiment, the second vertical beam 214 is provided with two second positioning parts 243, which are respectively close to the two second horizontal beams 213.

[0064] like Figure 5 As shown, one of the second crossbeams 213 has two first positioning pieces 241 at both ends along the second direction D2. The two first positioning pieces 241 are located on both sides of the plurality of second frames 220 along the second direction D2, and are used for positioning and engaging with the plurality of second frames 220 in the second direction D2. The other second crossbeam 213 has two second positioning pieces 242 at both ends along the second direction D2. The second positioning piece 242 has a first sub-piece 2421 and a second sub-piece 2422 that are vertically connected, forming an L-shape when connected. The two first sub-pieces 2421 are located on both sides of the plurality of second frames 220 along the second direction D2, and the two second sub-pieces 2422 are located on one side of the plurality of second frames 220 along the third direction D3.

[0065] like Figure 6As shown, the middle frame 210c and the middle of the multiple second frames 220 are respectively provided with third positioning parts 250, and the third positioning parts 250 are detachably connected to the middle of the second frame 220 by fasteners.

[0066] In one embodiment, the third positioning part 250 is a through hole, through which a fastener passes and connects to the second frame 220.

[0067] like Figure 6 As shown, mounting pieces 251 are respectively provided at the corresponding positions of the middle frame 210c and the middle of the plurality of second frames 220. The mounting pieces 251 are detachably connected to the middle of the second frame 220 by fasteners.

[0068] like Figure 6 As shown, the central frame 210c includes two third horizontal beams 215 and multiple third vertical beams 216. The third horizontal beams 215 extend along a second direction D2, and the two third horizontal beams 215 are spaced apart along a third direction D3. The multiple third vertical beams 216 are connected between the two third horizontal beams 215 and are spaced apart along the second direction D2. Among the multiple third vertical beams 216, the two outermost third vertical beams 216 are connected end-to-end with the two third horizontal beams 215 to form a rectangular frame.

[0069] In one embodiment, each third vertical beam 216 is provided with a third positioning part 250.

[0070] As an example, each third vertical beam 216 is provided with two third positioning parts 250, which are respectively close to the two third horizontal beams 215.

[0071] like Figure 6 As shown, each third vertical beam 216 is provided with a mounting plate 251, which is located on one side of the second frame 220 along the second direction D2.

[0072] As an example, each third vertical beam 216 is provided with two mounting pieces 251, which are respectively adjacent to the two third positioning parts 250.

[0073] like Figure 7 As shown, the second frame 220 includes a top beam 221, a bottom beam 222, an edge beam 223, an arc-shaped beam 224, and a middle beam 225. The top beam 221 and the bottom beam 222 are spaced apart along the first direction D1. The two ends of the edge beam 223 are respectively connected to one end of the top beam 221 and the bottom beam 222. The two ends of the arc-shaped beam 224 are respectively connected to the other ends of the top beam 221 and the bottom beam 222. The middle beam 225 is located at the middle position between the edge beam 223 and the arc-shaped beam 224.

[0074] Optionally, the second frame 220 further includes reinforcing beams 226. In one example embodiment, there are two reinforcing beams 226, namely a first reinforcing beam 226a and a second reinforcing beam 226b. One end of the first reinforcing beam 226a is connected to the end where the top beam 221 connects to the arc-shaped beam 224, and the other end of the first reinforcing beam 226a is connected to the end where the middle beam 225 connects to the side beam 223. One end of the second reinforcing beam 226b is connected to the end where the middle beam 225 connects to the arc-shaped beam 224, and the other end of the second reinforcing beam 226b is connected to the end where the bottom beam 222 connects to the side beam 223. Thus, the top beam 221, a portion of the side beams 223, and the first reinforcing beam 226a form a triangular structure, and the bottom beam 222, another portion of the side beams 223, and the second reinforcing beam 226b form a triangular structure. The triangular structure can significantly improve the overall rigidity of the second frame 220 and effectively suppress vibration and deformation.

[0075] In one embodiment, the bottom frame 210a is detachably connected to the bottom beams 222 of the plurality of second frames 220, the top frame 210b is detachably connected to the top beams 221 of the plurality of second frames 220, and the middle frame 210c is detachably connected to the middle beams 225 of the plurality of second frames 220. The plurality of arc-shaped beams 224 of the plurality of second frames 220 form an arc-shaped surface, and the outer shell 300 covers the arc-shaped surface.

[0076] As an example, the housing 300 can be bolted to the frame 200, which facilitates the replacement and maintenance of the housing 300.

[0077] Optionally, the housing 300 includes a plurality of independent sheets covering the curved surface.

[0078] In one embodiment, the outer shell 300 is provided with a through ventilation hole, which can effectively reduce wind resistance and reduce the risk of the cabin structure 100 overturning.

[0079] like Figure 3 As shown, a canvas 500 is attached to the side of the outer shell 300 facing away from the frame 200. The canvas 500 is magnetically attached to the outer shell 300 and / or the frame 200 via a magnetic component (not shown). The outer surface of the canvas 500 displays a visually simulated image. By using a canvas 500 with a visually simulated image, the realism of the training can be further enhanced. Furthermore, the magnetic connection of the canvas 500 facilitates its replacement and maintenance.

[0080] In one embodiment, the magnetic component may be a magnet.

[0081] In summary, the aircraft door simulator of this application has at least the following advantages and beneficial effects: The cabin structure 100 of this embodiment is a detachable and modular structure. The entire cabin structure 100 can be disassembled into several individual, easily transportable modules, facilitating manual handling and placement into standard transport containers.
