Description

Technical Field

[0002] The structure of the cabin used for escape, such as the escape exit of the aircraft cockpit is generally arranged on the top of the rear end of the cockpit. This escape exit is the exit used by the pilot to escape when the aircraft encounters an emergency landing. The pilot can use the equipment in the cockpit, such as the observer control panel and observer seat arranged at the rear end of the cockpit, the footrests on the rear wall panel of the cockpit, etc., and then extend the upper body out of the escape exit, and then support the hands on the cabin structure around the escape exit to climb out of the escape exit, but the escape efficiency of this method is low.

[0003] In addition, for wide-body aircraft, since the height of the cabin is higher than that of narrow-body aircraft, it is more difficult to escape from the above escape structure. For example, the height of the observer's console alone is not enough to reach the height of climbing out of the escape exit. Summary of the invention

[0057] Reference will now be made in detail to various embodiments of the present invention, examples of which are shown in the accompanying drawings and described below. Although the present invention will be described in conjunction with the exemplary embodiments, it should be appreciated that this specification is not intended to limit the present invention to those exemplary embodiments. On the contrary, the present invention is intended to cover not only these exemplary embodiments, but also various alternative forms, modifications, equivalent forms and other embodiments that may be included within the spirit and scope of the present invention as defined by the appended claims.

[0058] In the following description, the orientation or position relationship indicated by "upper", "lower", "inside", "outside", "middle" or other orientation terms is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0059] At the same time, the present application uses specific words to describe the embodiments of the present application. For example, "one embodiment" and / or "an embodiment" means a certain feature, structure or characteristic related to at least one embodiment of the present application. Therefore, it should be emphasized and noted that "one embodiment" or "an embodiment" mentioned twice or more in different positions in this specification does not necessarily refer to the same embodiment. In addition, certain features, structures or characteristics in one or more embodiments of the present application can be appropriately combined.

[0060] Flowcharts are used in this application to illustrate the operations performed by the system according to the embodiments of the application. It should be understood that the preceding or following operations are not necessarily performed precisely in order. Other operations may also be added to these processes, or one or more operations may be removed from these processes.

[0061] At present, the structure of the cabin used for escape, such as the escape exit of the cockpit of an aircraft, is generally arranged at the top of the rear end of the cockpit. This escape exit is the exit used by the pilot to escape when the aircraft encounters an emergency landing. The pilot can use the equipment in the cockpit, such as the observer console arranged at the rear end of the cockpit, the observer seat, the footrest on the rear wall of the cockpit, etc., and then extend the upper body to the escape exit, support the cabin structure around the escape exit with both hands, and climb out of the escape exit, but the escape efficiency of this method is low. In addition, for wide-body aircraft, since the height of the cabin is higher than that of narrow-body aircraft, it is more difficult to escape from the above escape structure. For example, the height of the observer console alone is not enough to reach the height of climbing out of the escape exit.

[0062] The escape structure used in wide-body aircraft includes the following comparison schemes:

[0063] Comparison Plan 1: Observer seats, observer control panels, cloakrooms and other equipment are arranged under the escape exit. With the help of the height difference and layout of these equipment, a ladder is formed to assist the pilot in climbing out of the escape exit during emergency escape.

[0064] Compared with Plan 2, an observer console, an observer seat and a folding foot pedal on the rear wall of the cockpit are arranged below the escape exit. When escaping, the pilot first steps on the observer console and then steps his right foot on the foot pedal to approach the escape exit.

[0065] After in-depth research, the inventor found that:

[0066] When using Comparative Plan 1, the escape route is more complicated. During the escape process, the pilot needs to accurately find the stepping points and climbing points of each device. The escape efficiency is low, and there is a risk of stepping on empty space or stepping unsteadily.

[0067] When using Comparative Scheme 2, after the pilot climbs up with the help of the folding foot pedal on the rear wall panel, it is still difficult to climb out of the escape exit. The pilot's left foot still needs a leverage point to climb out of the escape exit. Therefore, it is very likely that both hands will still be needed to support the cabin structure around the escape exit to climb out of the escape exit. The escape efficiency is also low, and because a leverage point is still needed, there is also a risk of stepping on empty space or stepping unsteadily.

[0068] Based on the above considerations, the inventor has conducted in-depth research and designed an escape device for the cabin. By setting a linkage part, the movement of the structural part is transmitted to the connecting part, and then the door body is rotated to open the escape exit, so as to realize the linkage opening of the ladder and the door. In the case of emergency escape of personnel, there will be no additional actions added, and the original action of opening the door is simply converted into lowering the ladder. The operation is convenient, and with the help of the escape device, the efficiency of emergency escape of personnel is improved. At the same time, by setting the first climbing force structure and the second climbing force structure to form a gradient climbing structure, the escapee can directly climb out of the escape exit through the gradient climbing to complete the escape, without having to support the cabin around the escape exit with both hands to climb out of the escape exit, thereby improving the escape efficiency; at the same time, the gradient climbing structure also reduces the risk of stepping into the air or stepping unsteadily, and improves the reliability and safety of the escape device.

[0069] Although the escape device disclosed in the embodiment of the present application is suitable for an aircraft with an escape exit arranged above the cockpit to improve the pilot's escape efficiency and success rate, it is not limited to this. For example, it can be applicable to other application scenarios, such as heavy vehicles, railway trains, submarines, cabins, etc., and can also be applicable to other independently arranged cabins, as long as the cabin structure can be applied with the escape device disclosed in the embodiment of the present application.

[0070] refer to Figure 1Combination Figure 2 , Figure 3 As shown, in one embodiment, the specific structure of the cabin assembly 1000 may include a cabin body 200 and an escape device 100. The cabin body 200 includes an escape exit 201 and a structural frame 202, and the escape device 100 is rotatably connected to the structural frame 202 of the cabin body 200.

[0071] The "cabin 200" herein specifically refers to a closed space having an exit that can be opened or closed to communicate with the outside world. The cabin 200 can exist independently or be part of a device. In some embodiments, the cabin assembly 1000 can be part of a vehicle, specifically, for example, a part of an aircraft, and the cabin assembly 1000 is the cockpit of the aircraft.

[0072] The "escape exit 201" here is different from the exit that usually connects the inside and the outside. The escape exit 201 is an escape exit used in an emergency. Figure 1 As shown, the escape exit 201 is arranged above the cabin 200 .

[0073] The “structural frame 202 ” here is a part of the fixed structure of the cabin 200 .

[0074] The “rotational connection” herein specifically refers to, for example, a pivot connection that enables the escape device to rotate relative to the structural frame.

[0075] The cabin assembly using the escape device can realize assisted escape without too much reliance on equipment inside the cabin.

[0076] Continue to refer Figure 1 Combination Figure 2 , Figure 3 As shown, in some embodiments, the specific structure of the cabin 200 may also include a skin 203 and an interior panel (not shown in the figure), the escape exit 201 is located on the skin 203, the structural frame 202 protrudes inward from the skin 203, the skin 203, the structural frame 202 and the interior panel form a storage space 204, and the escape device 100 is stored in the storage space 204.

[0077] The "structural framework 202" herein specifically includes, for example Figure 2 As shown, there are two long raised structures attached to the inner side of the skin 203 , located on both sides of the escape exit 201 , serving as a connection base between the escape device 100 and the cabin 200 .

[0078] The beneficial effect of such a configuration is that the escape device is stored between the skin and the interior panel, and under normal circumstances, the driver cannot see the escape device in the cabin. The installation of the escape device will not affect the aesthetics of the overall layout of the cabin, and at the same time, the space gap between the cabin interior panel and the skin can be effectively utilized.

[0079] refer to Figure 2 Combination Figure 4 , Figure 5 As shown, in one embodiment, the specific structure of the escape device 100 for the cabin 200 may include a door 1 and a ladder 2 .

[0080] The door 1 includes a door body 11 and a connecting portion 12. The connecting portion 12 has a first connecting position 121 and a second connecting position 122. The first connecting position 121 is used to be rotatably connected to the structural frame 202 of the cabin 200, so that the door body 11 can be rotated to open or close the escape exit 201 of the cabin 200. The door body 11 has a first climbing force structure 111. The ladder 2 includes a structural portion 21 and a linkage portion 22. The structural portion 21 has a second climbing force structure 211, a third connecting position 212, and a fourth connecting position 213. The fourth connecting position 213 of the structural portion 21 is used to be rotatably connected to the structural frame 202 of the cabin 200.

[0081] The structure part 21 of the ladder 2 is connected to the connection part 12 of the door 1 through the linkage part 22, the second connection position 122 of the connection part 12 is connected to one side of the linkage part 22, and the third connection position 212 of the structure part 21 is connected to the other side of the linkage part 22. The structure part 21 can be operated to rotate relative to the structure frame 202 to drive the door body 11 to rotate and open the escape exit 201 of the cabin 200, and the second climbing force structure 211 of the structure part 21 and the first climbing force structure 111 of the door body 11 can form a gradient climbing structure.

[0082] The "rotational connection" here can be realized, for example, by a pivot connection, where one side provides an axis and the other side provides an axis hole. Figure 5 , Figure 8 In the example shown, the first connection position 121 is the shaft 90, and the corresponding position of the structural frame 202 is the shaft hole 901; the fourth connection position 213 is the shaft 91, and the corresponding position of the structural frame 202 is the shaft hole 911. This arrangement is convenient for manufacturing and processing.

[0083] The term “operably” herein specifically means generally manual operation, which is convenient and reliable, but does not exclude automatic operation, such as providing a force to drive the structural part to rotate through motor control, so that the structural part rotates relative to the structural frame.

[0084] The "linking portion 22" herein may be a connecting rod 221 in some embodiments, for example Figure 3 , Figure 8 As shown, a connecting pin 80 is provided on the side where the connecting rod 221 is connected to the second connecting position 122, and the second connecting position 122 is a pin hole 801. A connecting pin 81 is provided on the side where the connecting rod 221 is connected to the third connecting position 212, and the third connecting position 212 is a pin hole 811. The positions of the connecting pin and the pin hole can also be that the pin hole is provided on the connecting rod, and the corresponding connecting position is the connecting pin.

[0085] The "gradient climbing structure" here specifically means that the positions of the first climbing support structure and the second climbing support structure have a suitable distance in a certain direction, such as the height direction, forming different levels of the gradient structure in this direction, which is convenient for people to step on different levels when climbing and escape from the escape exit.

[0086] The beneficial effect of this is that the movement of the structural part is transmitted to the connecting part by setting the linkage part, and then the door body part is rotated to open the escape exit, so as to realize the linkage opening of the ladder and the door. In the case of emergency escape of personnel, there will be no additional actions added, and the original action of opening the door is simply converted into lowering the ladder, which is convenient to operate. With the help of the escape device, the efficiency of emergency escape of personnel is improved. At the same time, by setting the first climbing force structure and the second climbing force structure to form a gradient climbing structure, the escapee can directly climb out of the escape exit through the gradient climbing to complete the escape, without having to support the cabin around the escape exit with both hands to climb out of the escape exit, thereby improving the escape efficiency; at the same time, the gradient climbing structure also reduces the risk of stepping into the air or stepping unsteadily, and improves the reliability and safety of the escape device.

[0087] refer to Figure 4 As shown, in some embodiments, the specific structure of the structural part 21 may include a first support arm 2101, a second support arm 2102 and a cross arm 2103, wherein the first support arm 2101 and the second support arm 2102 are respectively located on both sides of the cross arm 2103, the cross arm 2103 is fixedly connected to one side of the first support arm 2101 and the second support arm 2102, the fourth connection position 213 is located on the other side of the first support arm 2101 and the second support arm 2102, and the third connection position 212 is located in the middle of the first support arm 2101 and the second support arm 2102. The first support arm 2101, the second support arm 2102 and the cross arm 2103 form a window 2104, and the door body 11 can rotate to both sides of the window 2104.

[0088] The “middle” here is not limited to a strict middle position, and the third connection position 212 can select a suitable position between the cross arm 2103 and the fourth connection position 213 according to actual conditions.

[0089] The beneficial effect of such an arrangement is that the structural part is a frame with a window, which can make the structure more compact, facilitate folding and storage when the escape device is folded, and also facilitate climbing when escaping.

[0090] Continue to refer Figure 4 Combination Figure 5 As shown, in some embodiments, the specific structure of the escape device 100 can be that the first climbing traction structure 111 and the second climbing traction structure 211 include a pedal 7, and the pedal 7 is fixedly connected to the cross arm 2103 and the side 1101 of the door body 11 away from the cross arm 2103.

[0091] The "pedal 7" herein has multiple, for example Figures 4 to 6 In the embodiment shown, there are four pedals 7, two on the cross arm 2103 and two on the side 1101 of the door body 11. The pedal 7 on the cross arm 2103 can be called a first pedal 71, and the pedal 7 on the side 1101 of the door body can be called a second pedal 72. When a person escapes, he first steps on the first pedal 71, then steps on the second pedal 72, and climbs out of the escape exit 201. In some embodiments, as Figure 3 As shown, the inner side of the structural frame 202 is provided with a groove 2021, which is used to accommodate the pedal 7 when the escape device 100 is folded, so that the structure is more compact and the escape device 100 is smaller when folded. It can be understood that the structure of the pedal 7 is not limited to the structure of each level of pedals having two small pedals as shown in the figure, for example, each level of pedals can also have more small pedals, or each level of pedals can be an integral large pedal (for example, the two small pedals in the figure are parts at the two ends of the large pedal), etc.

[0092] The beneficial effect of such a setting is that multiple fixed pedals are provided to form a step structure, providing multiple climbing traction points, which can enable people to climb out of the escape exit safely and smoothly, effectively improving the reliability and safety of the escape device, reducing the situation where people step on empty air or step unstable when escaping, and improving the success rate of escape.

[0093] refer to Figures 2 to 5 As shown, in some embodiments, the specific structure of the door 1 may include a locking device 13, which is located on the inner side 1102 of the door body 11 and is used to lock the connection between the escape device 100 and the structural frame 202. The beneficial effect of such a setting is that the structure is simple and the operation is convenient.

[0094] The "locking device 13" herein is specifically, for example Figure 2 , Figure 3 , Figure 5As shown, it may include a lock tongue 1301, an operating portion 1302, and a lock body 1303. The lock tongue 1301 is controlled to be retracted into the lock body 1303 or extended out of the lock body 1303 by twisting the operating portion 1302. A lock hole 1304 is provided on the corresponding structural frame 202. The operating portion 1302 is twisted to make the lock tongue 1301 extend out of the lock body 1303 and insert into the lock hole 1304, thereby locking the door 1 and then locking the escape device 100, so that the escape device 100 remains retracted in the storage space 204.

[0095] refer to Figure 2-3 Combination Figure 7A-7B As shown, in some embodiments, the specific structure of the escape device 100 may include a first state structure and a second state structure:

[0096] In the first state structure, such as Figure 3 , Fig. 7A As shown, the angle θ between the linkage part 22 and the line a between the first connection position 121 and the second connection position 122 is an obtuse angle, the door body 11 is located at the first rotation position 112, located on one side of the window 2104, and the door body 11 closes the escape exit 201. At this time, the cabin assembly 1000 is in a normal state, and the escape device 100 is stored in the storage space 204.

[0097] In the second state structure, such as Figure 2 , Figure 7B As shown, the angle θ between the linkage part 22 and the line a connecting the first connection position 121 and the second connection position 122 is an acute angle, the door body 11 is located at the second rotation position 113, located on the other side of the window 2104, and the door body 11 opens the escape exit 201. At this time, the cabin assembly 1000 is in an emergency state, the escape device 100 is deployed, and the personnel use the escape device 100 to climb to the escape exit 201 to escape from the cabin 200.

[0098] refer to Figure 2-3 Combination Figure 5-6 As shown, in some embodiments, the specific structure of the escape device 100 may be that the structural portion 21 includes a fifth connection position 214, and the fifth connection position 214 is located at the first support arm 2101 and the second support arm 2102. The escape device 100 also includes a buffer 3, one side of the buffer 3 is rotatably connected to the structural frame 202, and the other side of the buffer 3 is rotatably connected to the fifth connection position 214, for buffering the folding and unfolding of the escape device 100.

[0099] The "rotational connection" here can be achieved through a pivot structure, with one party providing an axis and the other party providing a hole that matches the axis.

[0100] Here, "cushioning the folding and unfolding of the escape device 100" specifically means that when the escape device 100 is unfolded and lowered, the buffer 3 provides an upward pulling force to prevent the ladder 2 and the door 1 from falling freely under the action of gravity and injuring the operator or colliding with the cabin 200 to cause damage. When the escape device 100 is folded, the buffer 3 provides a downward pulling force to prevent the sealing between the door body 11 and the skin 203 from being affected by excessive folding. In some embodiments, such as Figure 8 As shown, the buffer 3 is a gas spring device 31, one side of the gas spring device 31 includes a pin hole 821, which is rotatably connected to the pin 82 on the structural frame 202, and the other side of the gas spring device 31 includes a pin 83, which is rotatably connected to the pin hole 831 of the fifth connection position 214. This is a purely mechanical structure with high reliability. The buffer 3 can also be a hydraulic spring device, as long as it is a device with bidirectional damping and can be applied.

[0101] The beneficial effect of such a setting is that it can improve the convenience of personnel using the escape device and ensure the safety of personnel and the device.

[0102] refer to Figure 2 Combination Figure 3 As shown, in some embodiments, the specific structure of the escape device 100 may also include a limit stop block 4, which is fixedly connected to the structural frame 202 and is used to constitute a stop point in the unfolding and rotating process of the escape device 100. The beneficial effect of such a setting is that the ladder can be limited to a suitable unfolding position, so that the first climbing force structure and the second climbing force structure form a better gradient climbing structure, thereby improving the convenience, safety and success rate of personnel escape.

[0103] refer to Figure 2 Combination Figure 4 As shown, in some embodiments, the specific structure of the escape device 100 may also include a handle 5, which is fixedly connected to the cross arm 2103. Such a configuration makes the deployment of the escape device more convenient and labor-saving, thereby improving the escape efficiency.

[0104] refer to Fig. 9 As shown, in one embodiment, the vehicle includes a cabin, the cabin has an escape exit and a corresponding door, and a ladder linked to the door. The specific steps of the escape method of the vehicle may include:

[0105] S1. The door is released from its retracted state. Figure 2-8 As shown, the personnel inside the cabin 200 remove the interior panel corresponding to the position of the escape device 100 to expose the escape device 100, and manually twist the operating part 1302 to make the lock tongue 1301 leave the lock hole 1304 and retract into the lock body 1303, so that the door body 11 is contacted and locked, and then the escape device 100 is contacted and locked.

[0106] S2. The ladder is operated to release the stowed state of the ladder, and the ladder moves from the stowed state position, and drives the door that releases the stowed state to rotate, until the ladder is moved to the first predetermined position, and the door is driven to the second predetermined position; at this time, the ladder at the first predetermined position provides a first climbing force structure, and the door at the second predetermined position provides a second climbing force structure. The first climbing force structure and the second climbing force structure constitute a gradient climbing structure for people to climb out of the escape exit. Figure 2-8 As shown, the person inside the cabin 200 pulls the handle 5 downward, the ladder 2 rotates and unfolds downward around the fixed axis b, and the movement is transmitted to the connecting part 12 through the linkage part 22, driving the door 1 to rotate around the fixed axis to open the escape exit 201. The handle 5 is pulled to rotate the escape device 100 until the limit block 4 blocks the structural part 21 of the ladder 2 and cannot continue to rotate. At this time, the escape device 100 is in the second state structure, and the first pedal 71 and the second pedal 72 constitute a second step. The person inside can smoothly pass through the escape exit and escape from the cabin 200 by climbing the escape device 100.

[0107] With the above escape method, the folding and lowering process only relies on the interaction of the mechanical structure, and does not require any auxiliary energy, thereby ensuring the reliability of the escape method. At the same time, the escape exit can be opened by the linkage door only by operating the ladder, thereby improving the efficiency of escape. In addition, the climbing of the step-type gradient structure allows the escapee to directly climb out of the escape exit through the continuous climbing of the step-type gradient structure to complete the escape, without having to support the cabin around the escape exit with both hands to climb out of the escape exit, thereby improving the escape efficiency; at the same time, the step-type gradient structure also reduces the risk of stepping into the air or stepping unsteadily, thereby ensuring the safety of the escape process.

[0108] Although the present invention is disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, any modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the protection scope defined by the claims of the present invention.
