Description

Technical Field

[0001] This invention belongs to the field of passenger aircraft technology, specifically a detachable escape cabin. Background Technology

[0002] With the development of aviation technology, the safety and comfort of passenger aircraft have been significantly improved. Modern passenger aircraft have become increasingly complex in structural design and are widely used in various air transport services. The design of a passenger aircraft typically includes key components such as the fuselage, cabin, power system, and flight control system, among which the connection structure between the fuselage and cabin is particularly important. The cabin is usually the activity area for passengers and crew, providing a comfortable travel environment.

[0003] In most current passenger aircraft designs, the fuselage and cabin are tightly integrated and do not employ a structure that allows for rapid separation in emergencies. When an aircraft encounters unforeseen circumstances, such as structural damage, fire, severe weather, or other emergencies, the inability to separate the fuselage and cabin can lead to serious safety hazards. Without a separation mechanism between the cabin and fuselage, passenger escape routes are restricted in the event of an accident, potentially resulting in greater casualties. Although some passenger aircraft employ separation mechanisms to deal with emergencies, some separation mechanisms require a long reaction time and cannot fully guarantee passenger safety, especially during sea landings. Furthermore, some cabin separation mechanisms require manual operation.

[0004] In conclusion, there is an urgent need for a more efficient, reliable, and safer technology for separating the fuselage from the cabin, especially in situations such as emergency landings and sea landings, to better protect the lives of passengers. Summary of the Invention

[0005] To address the problems mentioned in the background section, the present invention provides a detachable escape cabin.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a detachable escape cabin, comprising a fuselage and a cabin:

[0007] The compartment is located on one side of the machine body, and multiple frames are fixedly installed on the inner wall of the compartment.

[0008] Multiple fixed plates are slidably disposed on the inner walls of multiple frames, and a transmission rod is fixedly disposed on one side of each of the multiple fixed plates. The multiple fixed plates can slide on the inner walls of multiple frames, and the multiple frames connect the multiple fixed plates and the machine body together.

[0009] Multiple push plates are fixedly installed at one end of multiple transmission rods, and the multiple push plates are in pairs. Hollow cylinders are movably sleeved on the outer surface of each of the multiple push plates. The multiple hollow cylinders have elasticity. The elasticity generated by the multiple hollow cylinders pushes the multiple push plates, and further through the multiple transmission rods, the multiple fixed plates are inserted into the interior of the multiple connecting plates, thereby further improving the connection strength between the body and the cabin.

[0010] Multiple connecting pipes are respectively installed on the outer surface of multiple hollow cylinders, and a diversion pipe is fixedly provided at one end of each of the multiple connecting pipes.

[0011] In the above technical solution, preferably, springs are movably installed on the inner walls of the multiple hollow cylinders. Multiple connecting plates, matching any one of the fixed plates, are fixedly installed on the side of the engine compartment near the fuselage. A square groove is formed on one side of the engine compartment, and multiple delivery pumps are installed on one side of the inner wall of the square groove. A first horizontal pipe is installed at the input end of the multiple delivery pumps. A sleeve is fixedly installed at one end of the first horizontal pipe. A hydraulic rod is installed on one side of the inner wall of the sleeve. A protrusion is fixedly installed at the output end of the hydraulic rod. A sealing ring is provided on the outer surface of the protrusion. The sleeve is movably fitted onto one end of the diversion pipe. In case of danger... By turning on the external power switches of multiple delivery pumps, suction is generated at the input ends of the multiple delivery pumps. During normal use, nitrogen is filled into the distribution pipe through the branch pipe, further filling the interior of multiple hollow cylinders with nitrogen. After filling, the sleeve is fitted onto the outer surface of the distribution pipe, and the output end of the hydraulic rod is controlled to move the protrusion downward, so that the protrusion is inserted into the inner wall of the distribution pipe to prevent gas leakage from the inside of the distribution pipe. The sealing ring improves the sealing effect of the protrusion. In case of danger, the output of the hydraulic rod is controlled to move upward. At this time, suction is generated at the input ends of multiple delivery pumps, and gas inside the distribution pipe is drawn in through the first horizontal pipe and the branch pipe.

[0012] In the above technical solution, a preferred embodiment has a storage slot on one side of the cabin, an airbag installed on one side of the inner wall of the storage slot, and multiple protruding plates fixedly installed on one side of the inner wall of the storage slot. A horizontal axis is fixedly installed on the inner wall of each of the multiple protruding plates, and the multiple protruding plates support the multiple horizontal axes.

[0013] In the above technical solution, preferably, baffles are movably sleeved on the outer surfaces of the plurality of horizontal shafts, and mounting plates are fixedly provided on one side of the plurality of baffles. The plurality of baffles can slide on the outer surfaces of the plurality of horizontal shafts respectively. By rotating the plurality of baffles, the plurality of mounting plates come into contact with one side of the inner wall of the storage groove.

[0014] In the above technical solution, preferably, a magnet is fixedly provided on one side of each of the multiple mounting plates, an inflation port is provided on the outer surface of the airbag, the multiple mounting plates support the multiple magnets, and the multiple mounting plates are fixed inside the storage groove by the attraction of the multiple magnets. Multiple baffles support the airbag. Since the airbag is small in volume when it is not inflated, the multiple baffles can support the airbag. When it is inflated, the airbag expands and its volume increases, which will knock open the multiple mounting plates.

[0015] In the above technical solution, preferably, a guide tube is installed at one end of the inflation port, a second crossbar is installed at one end of the guide tube, and multiple second crossbars are installed on the output ends of multiple delivery pumps. The nitrogen gas drawn in by the multiple delivery pumps is discharged into the interior of the second crossbar through the output ends, and further inflates the airbag through the guide tube and the inflation port.

[0016] In the above technical solution, preferably, two mounting brackets are fixedly installed on the inner wall of the cabin, and parachutes are installed on the inner walls of the mounting brackets. Two transverse grooves are opened on the inner wall of the cabin. One of the transverse grooves has a double-threaded rod on both sides of its inner wall through bearings. Two sleeves are threaded on the outer surface of the double-threaded rod. The other transverse groove has a round rod fixed on both sides of its inner wall. Two sliding cylinders are movably fitted on the outer surface of the round rod. The two mounting brackets serve to install the two parachutes. When the cabin falls downward, the arc plate separates from the cabin, and the parachutes inside the two mounting brackets pop open, changing the air resistance of the cabin and slowing down the falling speed. The outer surfaces of the two double-threaded rods have two threaded grooves with different directions of rotation. The two sleeves are respectively connected to the two threaded grooves with different directions of rotation on the outer surfaces of the double-threaded rods, and the two sliding cylinders can slide on the outer surface of the round rod. Thus, when the double-threaded rod rotates in different directions, the two sleeves move in relative or opposite directions on the outer surface of the double-threaded rod.

[0017] In the above technical solution, preferably, the two sliding cylinders are connected to the two sleeves respectively through two transmission plates. Multiple positioning rods are fixedly provided on the opposite side of the two transmission plates. A base plate is movably sleeved on the outer surface of the multiple positioning rods. The multiple positioning rods slide out of the interior of the multiple second through holes and the multiple first through holes. The multiple base plates are not stuck by the multiple positioning rods, which further loosens the arc plate.

[0018] In the above technical solution, preferably, an arc-shaped plate is fixedly provided on one side of each of the multiple base plates, and a first through hole is opened on one side of each of the multiple base plates. Any one of the first through holes matches any one of the positioning rods. Multiple second through holes are opened on the inner wall of the cabin, and multiple positioning rods are respectively movably embedded in the inner wall of the multiple second through holes. A partition is fixedly provided on one side of the inner wall of the cabin. The partition has the function of separating the two parachutes and preventing the bottoms of the two parachutes from getting tangled together.

[0019] In the above technical solution, preferably, a bidirectional motor is installed on the inner wall of one of the transverse grooves. The output shaft of the bidirectional motor is fixedly equipped with a rotating rod. A first gear is fixedly sleeved on the outer surface of the rotating rod. A second gear is meshed on the outer surface of the first gear. The second gear is fixedly sleeved on the outer surface of the bidirectional threaded rod. When the external power switch of the bidirectional motor is turned on, the output shaft of the bidirectional motor can rotate in both directions. Then, the output shaft of the bidirectional motor drives the rotating rod to rotate, which in turn drives the rotating rod to rotate, and then the second gear causes the bidirectional threaded rod to rotate.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This invention involves turning on the external power switches of multiple delivery pumps, thereby generating suction at the input ends of these pumps. This suction controls the hydraulic rod output to move upwards. At this time, the suction generated at the input ends of the multiple delivery pumps draws in gas from inside the distribution pipe through the first horizontal pipe and branch pipe. Multiple push plates can slide along the inner walls of multiple hollow cylinders. The gas inside the hollow cylinders is then discharged into the distribution pipe through multiple connecting pipes, and further discharged by the multiple delivery pumps. The hollow cylinders possess elasticity, and this elasticity pushes the push plates, which in turn are further discharged through multiple transmission... The rods allow multiple fixed plates to be inserted into the interior of multiple connecting plates, further enhancing the connection strength between the fuselage and the cabin. At this time, the gas inside the multiple hollow cylinders is sucked out. Under the action of suction, multiple push plates can slide on the inner walls of the multiple hollow cylinders. At this time, multiple transmission rods, guided by the multiple push plates, pull multiple fixed plates, causing the multiple fixed plates to slide out from the inner walls of the multiple connecting plates. Then, under the action of gravity, the fuselage falls downward, completing the separation between the fuselage and the cabin. Thus, when using a passenger aircraft, the fuselage and the cabin can be separated, and the separation method is relatively simple.

[0022] 2. This invention uses multiple delivery pumps to draw in nitrogen gas, which is then discharged into the second crossbar through the output end. The gas is further inflated through a guide pipe and inflation port. During normal use, multiple baffles can slide on the outer surfaces of multiple crossbars, and multiple convex plates support the crossbars. By rotating the baffles, multiple mounting plates contact one side of the inner wall of the storage slot. Multiple magnets then fix the mounting plates inside the storage slot. The baffles support the airbag. When the airbag is not inflated, its small size allows the baffles to support it. When inflated, the airbag expands, causing it to break open the mounting plates, further positioning the airbag inside the cabin and supporting it. If the cabin lands on land, the airbag acts as a buffer; if it lands at sea, the airbag acts as a floatation device, preventing the cabin from sinking. Passengers can then wait for rescue quietly. This increases the chances of survival during cabin separation, especially during water landings, as it keeps the cabin afloat and prevents it from sinking.

[0023] 3. This invention, by turning on the external power switch of the bidirectional motor, causes the output shaft of the bidirectional motor to drive the rotating rod to rotate. Since there are two threaded grooves with different directions of rotation on the outer surface of the two bidirectional threaded rods, the two sleeves are connected to the two threaded grooves with different directions of rotation on the outer surface of the bidirectional threaded rods, and the two sliding cylinders can slide on the outer surface of the round rods. Thus, when the bidirectional threaded rods rotate in different directions, the two sleeves move in opposite or opposite directions on the outer surface of the bidirectional threaded rods. At this time, the output shaft of the bidirectional motor is controlled to rotate counterclockwise, which further drives the rotating rod to rotate, and then drives the bidirectional threaded rod to rotate counterclockwise through the second gear. This causes the two sleeves to drive the two transmission plates to move in opposite directions, so that multiple positioning rods slide out of the interior of multiple second through holes and multiple first through holes. Multiple base plates are not stuck by multiple positioning rods, which further loosens the arc plate. When the cabin falls downward, the arc plate separates from the cabin, and the parachutes inside the two mounting frames pop out, changing the air resistance of the cabin and slowing down the falling speed. Thus, when the cabin lands, the falling speed of the cabin can be slowed down, reducing the impact force upon landing. This improves cabin safety during landing. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figures 1 to 15 As shown, the present invention provides a separable escape cabin, which includes a body 1 and a cabin 2: a compartment 201 is opened on one side of the body 1, and multiple frames 202 are fixedly installed on the inner wall of the compartment 201.

[0042] Multiple fixed plates 203 are slidably disposed on the inner walls of multiple frames 202, and a transmission rod 204 is fixedly disposed on one side of each of the multiple fixed plates 203;

[0043] Multiple push plates 205 are fixedly installed at one end of multiple transmission rods 204, and the multiple push plates 205 are in pairs. Hollow cylinders 206 are movably sleeved on the outer surface of the multiple push plates 205.

[0044] Multiple connecting pipes 208 are respectively installed on the outer surface of multiple hollow cylinders 206, and a diversion pipe 209 is fixedly provided at one end of each connecting pipe 208. Springs 207 are movably provided on the inner wall of each hollow cylinder 206. Multiple connecting plates 210 matching any one of the fixed plates 203 are fixedly provided on the side of the cabin 2 near the body 1. A square groove 211 is opened on one side of the cabin 2. Multiple delivery pumps 212 are installed on one side of the inner wall of the square groove 211. A first horizontal pipe 213 is installed at the input end of the multiple delivery pumps 212. A sleeve 215 is fixedly provided at one end of the first horizontal pipe 213. A hydraulic rod 216 is installed on one side of the inner wall of the sleeve 215. A protrusion 217 is fixedly provided at the output end of the hydraulic rod 216. A sealing ring 218 is provided on the outer surface of the protrusion 217. The sleeve 215 is movably sleeved on one end of the diversion pipe 209.

[0045] Multiple fixed plates 203 are located on the inner walls of multiple connecting plates 210. The cabin 2 is connected to the fuselage 1 via the multiple connecting plates 210 and the multiple fixed plates 203. In case of danger, the external power switches of multiple delivery pumps 212 are turned on, thereby generating suction at the input ends of the multiple delivery pumps 212. During normal use, nitrogen is filled into the diversion pipe 209 through the branch pipe 214, further filling the interior of multiple hollow cylinders 206 with nitrogen. The multiple hollow cylinders 206 have elasticity, and the multiple hollow cylinders 206 generate The elastic force pushes multiple push plates 205 respectively, and further through multiple transmission rods 204, multiple fixing plates 203 are inserted into the interior of multiple connecting plates 210, further improving the connection strength between the body 1 and the cabin 2. After inflation is completed, the sleeve 215 is fitted on the outer surface of the diversion pipe 209, and the output end of the control hydraulic rod 216 drives the protrusion 217 to move down, so that the protrusion 217 is inserted into the inner wall of the diversion pipe 209, preventing the gas inside the diversion pipe 209 from leaking out. The sealing ring 218 improves the sealing effect of the protrusion 217.

[0046] When danger occurs, the hydraulic rod 216 moves upward, and the input ends of multiple delivery pumps 212 generate suction, drawing in gas from inside the diversion pipe 209 through the first horizontal pipe 213 and branch pipe 214. Multiple push plates 205 can slide on the inner walls of multiple hollow cylinders 206. At this time, the gas inside the multiple hollow cylinders 206 is discharged into the diversion pipe 209 through multiple connecting pipes 208, and further discharged through multiple delivery pumps 212. At this time, the gas inside the multiple hollow cylinders 206 is sucked out. Under the action of suction, multiple push plates 205 can slide on the inner walls of multiple hollow cylinders 206. At this time, multiple transmission rods 204, guided by multiple push plates 205, pull multiple fixed plates 203, causing multiple fixed plates 203 to slide out of the inner walls of multiple connecting plates 210. At this time, under the action of gravity, the body 1 falls downward, completing the separation between the body 1 and the cabin 2.

[0047] Please see Figures 1 to 15 In one embodiment, a storage slot 3 is provided on one side of the cabin 2. An airbag 301 is installed on one side of the inner wall of the storage slot 3. A plurality of protruding plates 302 are fixedly provided on one side of the inner wall of the storage slot 3. A horizontal axis 303 is fixedly provided on the inner wall of each of the plurality of protruding plates 302. The plurality of protruding plates 302 support the plurality of horizontal axes 303.

[0048] Please see Figures 1 to 15 In one embodiment, baffles 304 are movably sleeved on the outer surfaces of multiple horizontal shafts 303, and mounting plates 305 are fixedly provided on one side of each of the multiple baffles 304. The multiple baffles 304 can slide on the outer surfaces of the multiple horizontal shafts 303 respectively. By rotating the multiple baffles 304, the multiple mounting plates 305 come into contact with one side of the inner wall of the storage groove 3.

[0049] Please see Figures 1 to 15 In one embodiment, a magnet 306 is fixedly provided on one side of each of the multiple mounting plates 305, and an inflation port 307 is provided on the outer surface of the airbag 301. The multiple mounting plates 305 support the multiple magnets 306. The multiple mounting plates 305 are fixed inside the storage groove 3 by the attraction of the multiple magnets 306. Multiple baffles 304 support the airbag 301. Since the airbag 301 is small when it is not inflated, the multiple baffles 304 can support the airbag 301. When it is inflated, the airbag 301 expands and its volume increases, which will knock open the multiple mounting plates 305.

[0050] Please see Figures 1 to 15 In one embodiment, a guide tube 308 is installed at one end of the inflation port 307, and a second crossbar 309 is installed at one end of the guide tube 308. Multiple second crossbars 309 are installed on the output ends of multiple delivery pumps 212. The nitrogen gas drawn in by the multiple delivery pumps 212 is discharged into the second crossbar 309 through the output end, and further inflates the airbag 301 through the guide tube 308 and the inflation port 307.

[0051] Please see Figures 1 to 15In one embodiment, two mounting brackets 4 are fixedly installed on the inner wall of the cabin 2. Parachutes 401 are installed on the inner walls of each mounting bracket 4. Two transverse grooves 402 are formed on the inner wall of the cabin 2. A double-threaded rod 403 is mounted on both sides of the inner wall of one of the transverse grooves 402 via bearings. Two sleeves 404 are threaded onto the outer surface of the double-threaded rod 403. A round rod 405 is fixedly installed on both sides of the inner wall of the other transverse groove 402. Two sliding cylinders 406 are movably mounted on the outer surface of the round rod 405. The two mounting brackets 4 serve to mount the two parachutes 401 in the cabin 2. When falling downwards, the arc plate 411 separates from the cabin 2, and the parachutes 401 inside the two mounting frames 4 pop out, changing the air resistance of the cabin 2 and slowing down the falling speed. The outer surfaces of the two bidirectional threaded rods 403 have two threaded grooves with different directions of rotation. The two sleeves 404 are connected to the two threaded grooves with different directions of rotation on the outer surfaces of the bidirectional threaded rods 403, and the two sliding cylinders 406 can slide on the outer surface of the round rod 405. Thus, when the bidirectional threaded rods 403 rotate in different directions, the two sleeves 404 move in relative or opposite directions on the outer surfaces of the bidirectional threaded rods 403.

[0052] Please see Figures 1 to 15 In one embodiment, two sliding cylinders 406 are connected to two sleeves 404 respectively through two transmission plates 407. Multiple positioning rods 408 are fixedly provided on opposite sides of the two transmission plates 407. A base plate 410 is movably sleeved on the outer surface of the multiple positioning rods 408. The multiple positioning rods 408 slide out of the interior of multiple second through holes 417 and multiple first through holes 412. The multiple base plates 410 are not stuck by the multiple positioning rods 408, which further loosens the arc plate 411.

[0053] Please see Figures 1 to 15 In one embodiment, an arc-shaped plate 411 is fixedly provided on one side of each of the multiple base plates 410, and a first through hole 412 is provided on one side of each of the multiple base plates 410. Any one of the first through holes 412 is matched with any one of the positioning rods 408. A multiple second through holes 417 are provided on the inner wall of the cabin 2. The multiple positioning rods 408 are respectively movably embedded in the inner wall of the multiple second through holes 417. A partition 409 is fixedly provided on one side of the inner wall of the cabin 2. The partition 409 has the function of separating the two parachutes 401 to prevent the bottoms of the two parachutes 401 from getting tangled together.

[0054] Please see Figures 1 to 15In one embodiment, a bidirectional motor 413 is installed on the inner wall of one of the transverse grooves 402. A rotating rod 414 is fixedly mounted on the output shaft of the bidirectional motor 413. A first gear 415 is fixedly sleeved on the outer surface of the rotating rod 414. A second gear 416 is meshed on the outer surface of the first gear 415. The second gear 416 is fixedly sleeved on the outer surface of the bidirectional threaded rod 403. When the external power switch of the bidirectional motor 413 is turned on, the output shaft of the bidirectional motor 413 can rotate in both directions. The output shaft of the bidirectional motor 413 drives the rotating rod 414 to rotate, which in turn drives the second gear 416 to rotate, and the second gear 416 causes the bidirectional threaded rod 403 to rotate.

[0055] The working principle and usage process of this invention are as follows: When separating the cabin 2, multiple fixing plates 203 are respectively located on the inner walls of multiple connecting plates 210. The cabin 2 is connected to the body 1 through multiple connecting plates 210 and multiple fixing plates 203. By turning on the external power switch of multiple delivery pumps 212, suction is generated at the input end of the multiple delivery pumps 212. During normal use, nitrogen is filled into the diversion pipe 209 through the branch pipe 214, further filling the interior of multiple hollow cylinders 206 with nitrogen. The multiple hollow cylinders 206 have elasticity. The elastic force generated by the hollow cylinder 206 pushes multiple push plates 205, which in turn, through multiple transmission rods 204, cause multiple fixing plates 203 to be inserted into the interior of multiple connecting plates 210, further improving the connection strength between the body 1 and the cabin 2. After inflation is completed, the sleeve 215 is fitted onto the outer surface of the diversion pipe 209, and the output end of the control hydraulic rod 216 drives the protrusion 217 to move downward, so that the protrusion 217 is inserted into the inner wall of the diversion pipe 209, preventing the gas inside the diversion pipe 209 from leaking out. The sealing ring 218 improves the sealing effect of the protrusion 217.

[0056] In case of danger, the control hydraulic rod 216 moves upward, causing multiple delivery pumps 212 to generate suction at their input ends. This suction draws gas from inside the diversion pipe 209 through the first horizontal pipe 213 and branch pipe 214. Multiple push plates 205 slide along the inner walls of multiple hollow cylinders 206. The gas inside the hollow cylinders 206 is then discharged into the diversion pipe 209 through multiple connecting pipes 208, and further discharged by the multiple delivery pumps 212. At this point, the gas inside the hollow cylinders 206 is... During suction, under the action of suction, multiple push plates 205 can slide on the inner walls of multiple hollow cylinders 206 respectively. At this time, multiple transmission rods 204, guided by multiple push plates 205, pull multiple fixed plates 203, causing multiple fixed plates 203 to slide out of the inner walls of multiple connecting plates 210. At this time, under the action of gravity, the fuselage 1 falls downward, completing the separation between the fuselage 1 and the cabin 2. Thus, when using the passenger aircraft, the fuselage 1 and the cabin 2 can be separated, and the separation method is relatively simple.

[0057] When the fuselage 1 and cabin 2 separate, nitrogen drawn in by multiple delivery pumps 212 is discharged into the second crossbar 309 through the output end, and further inflated into the airbag 301 through the guide pipe 308 and inflation port 307. During normal use, multiple baffles 304 can slide on the outer surface of multiple horizontal shafts 303, and multiple protruding plates 302 provide support for the multiple horizontal shafts 303. By rotating the multiple baffles 304, multiple mounting plates 305 come into contact with one side of the inner wall of the storage slot 3. The attraction of multiple magnets 306 fixes the multiple mounting plates 305 inside the storage slot 3. The multiple baffles 304 support the airbag 301. When the airbag 301 is not inflated, its small size allows multiple baffles 304 to support it. When inflated, the airbag 301 expands and its volume increases, which will break through multiple mounting plates 305, further placing the airbag 301 inside the cabin 2 to support the cabin 2. If the cabin 2 lands on land, the airbag 301 can act as a buffer. If the cabin 2 lands at sea, the airbag 301 can act as a floatation device, preventing the cabin 2 from sinking. Passengers can then wait quietly for rescue. This increases the chances of passenger survival when the cabin 2 separates, especially when landing on water, as it can keep the cabin afloat and prevent it from sinking.

[0058] After the fuselage 1 and cabin 2 separate, by turning on the external power switch of the bidirectional motor 413, the output shaft of the bidirectional motor 413 can rotate in both directions. This, in turn, drives the rotating rod 414 to rotate. Since the outer surfaces of the two bidirectional threaded rods 403 have two threaded grooves with different directions of rotation, the two sleeves 404 are respectively connected to these two grooves. Furthermore, the two sliding cylinders 406 can slide on the outer surface of the round rod 405. Therefore, when the bidirectional threaded rod 403 rotates in different directions, the two sleeves 404 move in opposite or relative directions on the outer surface of the bidirectional threaded rod 403. At this time, the output shaft of the bidirectional motor 413 is controlled to rotate counterclockwise, further driving the rotating rod 414... The second gear 416 is driven to rotate, which in turn causes the bidirectional threaded rod 403 to rotate counterclockwise. This causes the two sleeves 404 to drive the two transmission plates 407 to move in opposite directions, causing multiple positioning rods 408 to slide out of the multiple second through holes 417 and multiple first through holes 412. The multiple base plates 410 are not stuck by the multiple positioning rods 408, which further loosens the arc plate 411. When the cabin 2 falls downward, the arc plate 411 separates from the cabin 2, and the parachutes 401 inside the two mounting frames 4 pop out, changing the air resistance of the cabin 2 and slowing down the falling speed. Thus, when the cabin 2 lands, the falling speed of the cabin 2 can be slowed down, the impact force during landing can be reduced, and the safety of the cabin 2 during the landing process can be improved.
