Description

Technical Field

[0001] The present invention relates to the technical field of manned centrifuge training, and particularly to a manned centrifuge cockpit with higher safety and comfort. Background Art

[0002] The cockpit of a manned centrifuge is its core simulation test platform for simulating flight environments. The overall layout design of the cockpit needs to consider multiple factors. For example, it should meet the technical requirements of flight environment simulation, facilitate the overall structural design, ensure a clean and comfortable cabin environment, and guarantee sufficient operating space. At the same time, it also needs to meet the overall mass limit and weight distribution requirements, and ensure the load-bearing capacity and dynamic response performance of the cockpit.

[0003] Specifically, the cockpit needs to reasonably accommodate flight simulation equipment such as consoles, seats, and visual systems. Refer to Figure 1 A traditional cockpit layout scheme shown in the figure. This scheme uses a framework structure to carry various simulation components inside the cabin and forms a closed simulation space through skin encapsulation. Among them, the flight simulation console and seat are usually fixedly installed on the bottom load-bearing beam of the cabin; a load-bearing beam is provided at the top of the cockpit for hoisting an equipment installation bracket, and this bracket carries devices such as in-cabin instruments and projectors.

[0004] Although the above traditional cockpit layout solves the basic installation and load-bearing requirements of simulation equipment, it has significant defects. Since a manned centrifuge is mainly used for manned tests, it has high requirements for the safety and comfort of the cockpit environment. However, because most of the installed equipment is directly encapsulated in a closed cabin, the noise, heat, etc. generated during the operation of the equipment directly affect the acoustic environment and temperature and humidity indicators inside the cabin, reducing the comfort of the test personnel. At the same time, a large number of equipment are hoisted above the cabin roof and suspended above the heads of the test personnel. Under the strong centrifugal force field generated by high-speed rotation, such suspended structures and equipment have a risk of falling off, directly threatening the safety of the test personnel. During the test, operations such as temporary wiring of equipment are required, and the internal space of the installation bracket on the cabin roof is usually extremely narrow. The operator is forced to interact with the equipment in this limited space, making the operation difficult and inefficient, and the man-machine ergonomic performance is poor.

[0005] In summary, the traditional cockpit has problems such as poor cabin environment, poor operation safety, and limited man-machine interaction space. Therefore, it is urgent to optimize and improve the cockpit structure to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a manned centrifuge cockpit with higher safety and comfort to solve the technical problems of poor cabin environment, poor operation safety, and limited man-machine interaction space existing in the traditional cockpit in the prior art.

[0007] The present invention is achieved through the following technical solutions: A manned centrifuge cockpit with higher safety and comfort, including a cabin body, a cabin door, a console, instruments and seats. The cabin door is located below the cabin body. The console, instruments and seats are all arranged in the cabin body, and the seats are arranged opposite to the console. The cabin body includes a load-bearing structure and a skin covering the load-bearing structure. Among them, the load-bearing structure includes a top beam and a bottom beam arranged opposite to each other, and the top beam is fixedly connected to the bottom beam through a support beam. The top beam is formed into a sunken structure so that the area between the top beam and the top of the support beam forms an equipment bin for accommodating instruments. A skin is provided below the top beam so that the equipment bin and the internal space of the cabin body are relatively isolated.

[0008] Optionally, an installation bracket for installing a projector is provided on the top beam. The installation bracket is arranged on the side facing the inside of the cabin body, and the projector is arranged in the inner cavity of the installation bracket and encapsulated through a visual plate.

[0009] Optionally, the visual plate is configured as a glass substrate.

[0010] Optionally, a visual scene curtain is provided in the cabin body.

[0011] Optionally, a protection plate is provided on the top of the equipment bin, and a plurality of hollow holes are provided on the protection plate.

[0012] Optionally, the hollow holes are arranged in a rectangular array.

[0013] Optionally, an adapter panel electrically connected to the instrument is provided on the inner wall of the cabin body.

[0014] Optionally, a reinforcing plate is provided between the support beams, and a central hole is provided on the reinforcing plate.

[0015] Optionally, reinforcing ribs are provided on the reinforcing plate, and the reinforcing ribs radiate outward with the center of the central hole as the center.

[0016] Optionally, both the top beam and the bottom beam are configured as steel sections, and a plurality of support ribs arranged at intervals are provided between the two support surfaces of the steel section.

[0017] The beneficial effects of the invention and creation of the present disclosure compared with the prior art are: Through the above technical solution, the top beam adopts a sunken structure, forming an independent equipment compartment with the support beam. The instruments are integrated in the external space of the compartment roof, and the weight of the equipment is borne by the load-bearing structure. In this way, the electronic equipment can be stably integrated and carried in the top beam equipment compartment, eliminating the risk of detachment of the traditional suspension structure under centrifugal force, effectively avoiding the equipment from being suspended above the head in the cabin, and preventing the risk of equipment detachment caused by centrifugal force during high-speed rotation, thus ensuring the safety of the test personnel. Through the isolation equipment compartment and skin design formed by the sunken top beam, the noise and temperature in the cabin are effectively reduced, significantly improving the comfort of the test personnel. The top beam and the bottom beam are fixedly connected by the support beam to form a rigid frame structure, enhancing the load-bearing capacity and anti-deformation performance of the cockpit under a strong centrifugal force field. A skin is arranged below the top beam to physically isolate the equipment compartment from the space inside the cabin, forming an independent equipment operation area. This can not only block the noise generated by the equipment operation from spreading into the cabin, but also isolate the influence of equipment heat generation on the temperature and humidity in the cabin, improving the comfort of the test personnel. At the same time, because the equipment is centrally arranged in the independent compartment body, the operation and maintenance space is also optimized, improving the man-machine efficiency and maintenance convenience.

Detailed implementation manners

[0020] The present invention will be further described below in conjunction with the drawings and specific embodiments. It should be noted here that the description of these embodiment manners is for helping to understand the present invention, but does not constitute a limitation to the present invention. The specific structural and functional details disclosed herein are only used to describe the embodiments of the present invention. However, the present invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0021] According to the specific implementation manners of the present disclosure, a manned centrifuge cockpit with higher safety and comfort is provided. The manned centrifuge cockpit can effectively solve the problems of poor cabin environment, poor operation safety, and limited man-machine interaction space existing in the traditional cockpit. Among them, Figures 2 to 7 Its specific embodiments are shown.

[0022] The electronic instrument 4 on the cockpit is the main source of noise and heat. In this application, the skeleton structure of the cockpit is optimized, and at the same time, the skin 12 structure is adjusted correspondingly according to the new skeleton. The instrument 4 on the cabin is arranged on the cabin top, carried by the load-bearing beam on the cabin top, and isolated from the cabin interior environment through the skin 12 on the cabin top, basically eliminating the safety risks brought by the equipment on the cabin top to the test personnel, and at the same time reducing the influence of the equipment on the cabin top on the noise and temperature inside the cockpit.

[0023] Specifically, refer to Figures 2 to 7As shown in the figure, the manned centrifuge cockpit with higher safety and comfort includes a cabin body 1, a cabin door 2, a console 3, instruments 4 and a seat 5. The cabin door 2 is located below the cabin body 1. The console 3, the instruments 4 and the seat 5 are all arranged in the cabin body 1, and the seat 5 is arranged opposite to the console 3. The cabin body 1 includes a load-bearing structure 11 and a skin 12 covering the load-bearing structure 11. Among them, the load-bearing structure 11 includes a top beam 111 and a bottom beam 112 arranged opposite to each other, and the top beam 111 is fixedly connected to the bottom beam 112 through a support beam 113. The top beam 111 is formed into a sunken structure, so that the area between the top beam 111 and the top of the support beam 113 forms an equipment bin 10 for accommodating the instruments 4. A skin 12 is arranged below the top beam 111, so that the equipment bin 10 and the internal space of the cabin body 1 are relatively isolated.

[0024] Through the above technical solution, the top beam 111 adopts a sunken structure to form an independent equipment bin 10 with the support beam 113, so that the instruments 4 can be integrated into the external space of the cabin top. Thus, the load-bearing structure 11 bears the weight of the equipment. After the instruments 4 are firmly integrated and carried in the equipment bin 10 of the top beam 111, the top beam 111 and the skin 12 can jointly play a restraining role on the instruments 4, thereby eliminating the risk of the traditional suspension structure falling off under the centrifugal force. At the same time, since the instruments 4 are not directly suspended above the head in the cabin, the possibility of the equipment falling off due to the centrifugal force during high-speed rotation can be eliminated, ensuring the safety of the test personnel. In addition, a skin 12 is arranged below the top beam 111, which also physically isolates the equipment bin 10 from the cabin space, forming an independent equipment operation area. This can not only block the noise generated by the equipment operation from spreading into the cabin, but also isolate the influence of the equipment heat on the temperature and humidity in the cabin, improving the comfort of the test personnel.

[0025] In addition, through the coordinated design of the isolation equipment bin 10 and the skin 12 formed by sinking the top beam 111, the noise and temperature in the cabin can be effectively reduced, significantly improving the comfort of the test personnel. The top beam 111 and the bottom beam 112 are fixedly connected through the support beam 113 to form a rigid frame structure, enhancing the load-bearing capacity and anti-deformation performance of the cockpit under a strong centrifugal force field. At the same time, because the equipment is centrally arranged in an independent cabin, the operation and maintenance space is also optimized, improving the man-machine efficiency and maintenance convenience.

[0026] It should be noted that the orientation words such as "inside, outside" refer to "inside, outside" relative to the contour of the component. The direction towards the inside of the component (which can be understood in combination with Figure 2 is "inside", and vice versa. In addition, it should be noted that the terms such as "first", "second", etc. are used to distinguish one element from another, and do not have sequence and importance. Furthermore, in the following description of the drawings, the same reference numerals in different drawings represent the same elements.

[0027] In addition, it should be noted that the "instrument" in the present disclosure is not limited to a specific type of instrument, but is a general overview name, which includes but is not limited to electronic devices, electrical components, devices or systems.

[0028] In an embodiment provided by the present disclosure, a mounting bracket 61 for mounting a projector 62 is provided on the top beam 111. The mounting bracket 61 is arranged on the side facing the inside of the cabin 1, and the projector 62 is arranged in the inner cavity of the mounting bracket 61 and encapsulated by a viewing plate 63.

[0029] The mounting bracket 61 is fixed to the side of the top beam 111 facing the inside of the cabin 1, and forms a mounting base for the projector 62 through a rigid connection to ensure the reliability of the position of the projector 62. The mounting bracket 61 is made of a high-strength lightweight material, so that while meeting the weight-bearing requirement of the projector 62, it can be quickly disassembled and assembled through bolt connection. Thus, the mounting bracket 61 of the projector 62 meets the space requirements of the in-cabin visual system for the mounting position of the projector 62.

[0030] Specifically, the viewing plate 63 is a glass substrate and covers the side of the mounting bracket 61 facing the outside of the cabin. The glass substrate and the mounting bracket 61 together form an independent projector compartment.

[0031] In the present disclosure, the glass substrate is made of optically tempered glass with good light transmittance.

[0032] To ensure the sealing effect, a sound insulation sealing strip is provided at the edge of the viewing plate 63, so as to form a sealed structure with the mounting bracket.

[0033] Furthermore, a lockable maintenance access door is provided on the mounting bracket 61, which is convenient for tools to extend in to complete operations such as cleaning the lens of the projector 62 and plugging and unplugging cables.

[0034] Furthermore, a visual screen 7 is provided in the cabin 1. As the carrier of the visual system, the visual screen 7 can project dynamic images (such as scenes of the sky, ground, airport, etc.) through the projector 62, support scene transformation corresponding to flight attitudes such as pitch, roll, and yaw, ensure the synchronization of visual information with multi-dimensional stimuli such as centrifugal force field and operation feedback in the simulation test, thereby simulating the external visual environment in different flight states, enabling the test personnel to obtain an immersive sensory experience, and meeting the technical requirements of the manned centrifuge for flight environment simulation.

[0035] In the present disclosure, the frame of the visual screen 7 is fixedly connected to the inner wall of the cabin 1.

[0036] In the present disclosure, a protective plate 13 is provided on the top of the equipment compartment 10, and a plurality of hollow holes are provided on the protective plate 13. All the outward open windows in the equipment installation space on the top of the cabin are encapsulated by a hollow panel, such as Figure 6As shown, the safety of the equipment is ensured while also ensuring ventilation and heat dissipation.

[0037] The layout of the hollow holes forms an air circulation channel. When the centrifuge is running, the airflow outside the cabin can enter the equipment compartment 10 through the hollow holes, contact the surface of the heat-generating equipment (such as electronic instruments), take away the heat and then discharge it from other openings of the cabin body 1, thereby cooling the instrument 4 (or equipment) and preventing heat from accumulating in the equipment compartment 10, which would cause high-temperature aging or failure of the instrument 4.

[0038] Since the equipment compartment 10 is isolated from the cabin by the skin 12, the hollow holes of the protective plate 13 are only connected to the outside of the cabin, ensuring that the heat of the equipment is not directly transmitted into the cabin, maintaining a comfortable temperature in the cabin, avoiding discomfort to test personnel due to high temperature, and improving test safety.

[0039] In the present disclosure, the protective plate 13 is made of high-strength material (such as aluminum alloy or composite material), and the aperture and distribution of the hollow holes should be able to prevent external foreign objects (such as tools and parts) from falling into the equipment compartment 10 while ensuring ventilation, thereby preventing the equipment from being damaged by impact; at the same time, it can avoid the equipment being thrown out due to centrifugal force, thereby forming a secondary safety hazard.

[0040] Furthermore, the hollow holes are arranged in a rectangular array. The hollow holes arranged in a rectangular array can form a standardized ventilation unit, so that the airflow outside the cabin passes through the protective plate 13 vertically at a uniform speed, avoiding airflow turbulence caused by disordered hole positions, and ensuring that each heat-generating device (such as the power module of the projector) can be effectively cooled.

[0041] Furthermore, a dustproof net is provided on the protective plate 13, so that the dustproof net covers the hollow holes, thereby blocking external impurities without significantly reducing the ventilation volume, thereby providing better safety protection for the equipment.

[0042] In one embodiment provided in the present disclosure, an adapter panel 8 electrically connected to the instrument 4 is provided on the inner wall of the cabin body 1. The adapter panel 8 centrally arranges the electrical interfaces of the instruments 4 (such as sensors, controllers) in the cabin and external devices (such as consoles, power cabinets) to avoid confusion caused by scattered cable connections. The panel installation height is usually set within the range that the operator's arms can naturally reach when sitting (800~1200mm from the ground), and the inclination angle is designed to be 15°~30°, so that the operator can complete the plugging and unplugging operations without bending or raising his arms. During the test, the connection and other interactive operations between the adapter panel 8 in the cockpit and the equipment installed on the cabin are performed.

[0043] In the present disclosure, a reinforcing plate 114 is provided between the support beams 113, and the reinforcing plate 114 can suppress the local buckling (such as web shear buckling) of the support beam 113. When the span of the support beam 113 is large, the plate increases the critical buckling strength by constraining the lateral displacement of the beam.

[0044] Furthermore, a central hole 115 is provided on the reinforcing plate 114. The central hole 115 is located at the center of the reinforcing plate 114, which can balance the bending moments of the two side support beams 113 and avoid the torque effect caused by eccentric loads. At the same time, the setting of the central hole 115 also reduces the material usage of the reinforcing plate 114 and decreases the moment of inertia of the reinforcing plate 114. When the centrifuge rotates at a high speed, the fluctuation amplitude of the centrifugal force of the structure can be reduced, preventing resonance.

[0045] To improve the mechanical strength of the reinforcing plate 114, reinforcing ribs 116 are provided on the reinforcing plate 114. The reinforcing ribs 116 radiate outward with the center of the central hole 115 as the center. The radially arranged reinforcing ribs 116 are radially distributed with the central hole 115 as the origin (such as 6 to 20 evenly distributed ribs), which can guide and diffuse the radial stress and tangential stress at the hole edge along the rib direction. In this way, not only the overall strength of the reinforcing plate 114 is improved, but also the weight of the entire cabin 1 can be reduced.

[0046] In the present disclosure, both the top beam 111 and the bottom beam 112 are configured as profiled steels, and a plurality of support ribs 110 are arranged at intervals between the two support surfaces of the profiled steel. Specifically, after adding the spaced support ribs 110 between the two support surfaces (flanges) of the profiled steel (such as I-beam, H-beam), the tensile and compressive stress distributions of the upper and lower flanges of the beam are more uniform when the beam is subjected to bending. The support ribs 110 are connected to the flanges by welding to form a lateral constraint, preventing the lateral buckling of the flanges under compressive stress, thereby achieving a systematic improvement in the structural strength of the support beam 113. Not only the bending and torsion resistance performance is improved under static loads, but also the risk of vibration and deformation is effectively suppressed under dynamic conditions (such as when the centrifuge rotates at a high speed).

[0047] The above specific embodiments further elaborate on the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0048] Finally, it should be noted that the present invention is not limited to the above optional embodiments, and anyone can obtain other various forms of products under the inspiration of the present invention. The above specific embodiments should not be construed as limiting the protection scope of the present invention. The protection scope of the present invention should be defined by the claims, and the description can be used to interpret the claims.
