Description

Technical Field

[0001] The present invention relates to the field of flight automatic control, and particularly to a thrust reverser device. Background Art

[0002] The thrust reverser device is used to generate reverse thrust when an aircraft lands and during a rejected takeoff. When the thrust reverser is deployed, the movable cowl moves rearward, and at the same time, the bypass airflow is ejected against the flight direction to generate reverse thrust to decelerate the aircraft. The thrust reverser device is not allowed to be deployed in the air. In order to prevent the non-instructional movement of the movable cowl of the thrust reverser in the air, a locking device is required to lock the movable cowl.

[0003] In most of the currently active thrust reverser devices, most are hydraulic thrust reversers. The locking device is usually installed in the latch beam structure of the thrust reverser device. The thrust reverser device mostly adopts an actuator type. This type of locking device requires not only a power source but also a hydraulic source during the unlocking process. Correspondingly, in order to facilitate the use of hydraulic pressure, it is necessary to layout the inlet pipe and the return pipe in the latch beam. The pipelines of the inlet pipe and the return pipe need to be introduced from the suspension point, bypass the torque box and then pass through the latch beam, resulting in a relatively long pipeline length, which in turn causes an increase in the weight of the thrust reverser, and at the same time, the layout is complex and the maintenance cost is very high. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned defect of complex layout caused by the locking device of the thrust reverser device in the prior art using a hydraulic source, and to provide a thrust reverser device.

[0005] The present invention solves the above technical problem through the following technical solutions:

[0006] A thrust reverser device for an aircraft, the thrust reverser device includes a latch beam, a movable cowl slide rail, and an electromagnetic locking device. The movable cowl slide rail is provided with a locking groove; the electromagnetic locking device is fixedly arranged on the latch beam; the electromagnetic locking device switches between a locked state and an unlocked state; when the electromagnetic locking device is in the locked state, the locking hook of the electromagnetic locking device is clamped in the locking groove, and the movable cowl slide rail is locked relative to the latch beam; when the electromagnetic locking device is in the unlocked state, the locking hook of the electromagnetic locking device is away from the locking groove, and the movable cowl slide rail is unlocked relative to the latch beam.

[0007] In this solution, by adopting the above structure, the electromagnetic locking device is used to lock and unlock the sliding rail of the movable outer cover. The structure is simple, the control and operation are convenient, and it is safe and reliable. The introduction of a hydraulic source is avoided, the arrangement of complex hydraulic pipelines is avoided, and the total weight of the thrust reverser is reduced. The electromagnetic locking device is fixed on the locking beam, and the power supply line can be directly led out from the suspension, which is convenient for the power supply line to reach the electromagnetic locking device through the locking beam, avoiding the relevant cables from surrounding the torque box of the thrust reverser and then passing through the locking beam and finally reaching the conventional locking device, alleviating the problem of the tight layout space between the torque box and the locking beam, making the layout of the thrust reverser simpler, and at the same time reducing the weight of the thrust reverser.

[0008] Preferably, the electromagnetic locking device includes a housing, an elastic member, and an electrical component. The housing is fixedly arranged on the locking beam. The first end of the locking hook is pivotally arranged on the housing, and the second end of the locking hook extends towards the sliding rail of the movable outer cover. Both the elastic member and the electrical component act on the first end of the locking hook. When the electromagnetic locking device is in the locked state, the elastic member acts on the first end of the locking hook to make the second end of the locking hook approach the locking groove. When the electromagnetic locking device is in the unlocked state, the electrical component acts on the first end of the locking hook to make the second end of the locking hook move away from the locking groove.

[0009] In this solution, by adopting the above structure, the elastic member and the electrical component cooperate with each other to make the locking hook of the electromagnetic locking device approach or move away from the locking groove, thereby realizing the switching between the locked state and the unlocked state. The electromagnetic locking device has a simple structure and is convenient to use.

[0010] Preferably, one end of the elastic member is connected to the housing, and the other end of the elastic member is connected to the first end of the locking hook. The elastic member applies a pulling force to the locking hook.

[0011] In this solution, by adopting the above structure, the elastic member applies a pulling force, the direction of the pulling force is stable, and the pulling force can change with the change of the deformation amount of the elastic member, which can improve the stability during the movement of the locking hook and avoid excessive movement fluctuations of the locking hook.

[0012] Preferably, one end of the electrical component is fixedly arranged on the housing, and the other end of the electrical component extends towards the first end of the locking hook. The electrical component applies a pulling force towards the electrical component to the locking hook.

[0013] In this solution, by adopting the above structure, the pulling force applied by the electrical component to the locking hook can be changed instantaneously, which can improve the sensitivity of the locking hook, reduce the time during the movement of the locking hook, improve the locking or unlocking efficiency of the electromagnetic locking device, and improve the timeliness of the operation of the electromagnetic locking device.

[0014] Preferably, the elastic member and the electrical component are disposed on two opposite side surfaces of the first end of the locking hook.

[0015] In this solution, by adopting the above structure, the elastic member and the electrical component apply forces from two opposite sides of the first end respectively, thereby being able to restrict the lock hook from each other, thereby improving the flexibility and reliability of the lock hook movement.

[0016] Preferably, the lock hook further comprises a mounting hole, the first end and the second end are respectively located at two sides of the mounting hole, the lock hook is pivotally connected to the housing through the mounting hole, and the length of the second end of the lock hook is greater than the length of the first end of the lock hook;

[0017] And / or, the second end of the locking hook includes an extension section and a downward folding section, the extension section extends in the direction of the first end, and the downward folding section extends from the extension section toward the movable outer cover slide rail.

[0018] In the present solution, by adopting the above structure, the length of the second end of the locking hook is greater than the length of the first end of the locking hook, so that the second end can generate a larger force arm relative to the pivot axis, and then in a natural state, the second end will have a tendency to rotate downward, which can make the locking hook close to the locking groove, thereby preventing the locking hook from accidentally moving away from the locking groove, and improving the safety of the reverse thrust device.

[0019] The lower folding section can further increase the weight of the second end, further driving the second end to produce a downward rotation trend, which can make the lock hook close to the locking groove, can prevent the lock hook from accidentally leaving the locking groove, and can improve the safety of the reverse thrust device. The lower folding section can also hook the side of the sliding rail of the movable outer cover, and can further prevent the lock hook from accidentally leaving the locking groove, thereby improving the safety of the reverse thrust device.

[0020] Preferably, the electromagnetic locking device is provided on a side of the locking beam away from the movable outer cover slide rail, and the locking hook passes through the locking beam and is clamped in the locking groove.

[0021] In this solution, by adopting the above structure, the electromagnetic locking device is prevented from interfering with the movement of the movable outer cover slide rail, and the safety of the movement process of the movable outer cover slide rail can be improved.

[0022] Preferably, a through hole is provided on the lock beam, and the lock hook is passed through the through hole.

[0023] In this solution, by adopting the above structure, the relative position of the electromagnetic locking device and the locking beam is made more flexible, and the compactness of the structure of the reverse thrust device can also be improved.

[0024] Preferably, an extension plate is provided on the movable outer cover slide rail. The side surface of the extension plate is parallel to the extension direction of the locking beam, and the locking groove is provided on the top surface of the extension plate.

[0025] In this solution, by adopting the above structure, by providing the locking groove on the top surface of the extension plate, it is convenient to adjust the depth of the locking groove, so as to facilitate adapting to the movement of the locking hook, which can reduce the precision requirements for the installation of the electromagnetic locking device, and can also improve the tightness of the cooperation between the locking hook and the locking groove, and improve the safety and reliability of the reverse thrust device.

[0026] Preferably, the locking beam is provided with a sliding groove, and the sliding groove extends inward from the side surface of the locking beam;

[0027] The movable outer cover slide rail has an insertion section, and the insertion section is clamped in the sliding groove.

[0028] In this solution, by adopting the above structure, the sliding groove extends inward from the side surface of the locking beam, which can improve the structural compactness of the locking beam. The insertion section moves in the sliding groove, which can improve the stability of the movable outer cover slide rail during the movement process.

[0029] On the basis of conforming to the common knowledge in the art, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred examples of the present invention.

[0030] The positive and progressive effects of the present invention are as follows:

[0031] The present invention realizes the locking and unlocking of the movable outer cover slide rail by using the electromagnetic locking device, with a simple structure, convenient control and operation, and safe and reliable.

The electromagnetic locking device is fixed on the locking beam, and the power cord can be directly led out from the hanging, which is convenient for the power cord to reach the electromagnetic locking device through the locking beam, avoiding the relevant cables from surrounding the torque box of the reverse thrust device and then passing through the locking beam to finally reach the conventional locking device, alleviating the problem of the tight layout space between the torque box and the locking beam, making the layout of the reverse thrust device simpler, and at the same time reducing the weight of the reverse thrust device.

[0059] The present invention will be described more clearly and completely below by way of examples in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the examples.

[0060] As Figures 1 to 6As shown in the figure, this embodiment is a thrust reverser 100 for an aircraft. The thrust reverser 100 includes a latch beam 20, a movable outer cover slide rail 30, and an electromagnetic locking device 40. The movable outer cover slide rail 30 is provided with a locking groove 31; the electromagnetic locking device 40 is fixedly arranged on the latch beam 20; the electromagnetic locking device 40 switches between a self-locking state and an unlocking state; when the electromagnetic locking device 40 is in the locking state, the locking hook 41 of the electromagnetic locking device 40 is clamped in the locking groove 31, and the movable outer cover slide rail 30 is locked relative to the latch beam 20; when the electromagnetic locking device 40 is in the unlocking state, the locking hook 41 of the electromagnetic locking device 40 is away from the locking groove 31, and the movable outer cover slide rail 30 is unlocked relative to the latch beam 20. The locking and unlocking of the movable outer cover slide rail 30 are realized by using the electromagnetic locking device 40, with a simple structure, convenient control and operation, and being safe and reliable. It avoids introducing a hydraulic source, avoids arranging complex hydraulic pipelines, and reduces the total weight of the thrust reverser 100. The electromagnetic locking device 40 is fixed on the latch beam 20, and the power supply line can be directly led out from the suspension, which is convenient for the power supply line to reach the electromagnetic locking device 40 through the latch beam 20, avoiding the relevant cables from surrounding the torque box of the thrust reverser 100 and then passing through the latch beam 20 to finally reach the conventional locking device, alleviating the problem of the tight layout space between the torque box and the latch beam 20, making the layout of the thrust reverser 100 simpler, and at the same time reducing the weight of the thrust reverser 100.

[0061] As Figures 1 to 5 shown, only the latch beam 20, the movable outer cover slide rail 30, and the electromagnetic locking device 40 of the thrust reverser 100 are mainly shown in the figure, and other components of the thrust reverser 100, such as the movable outer cover, are not shown.

[0062] The electromagnetic locking device 40 includes a housing 42, an elastic member 43, and an electrical component 44. The housing 42 is fixedly arranged on the latch beam 20. The first end 45 of the locking hook 41 is pivotally arranged on the housing 42, and the second end 46 of the locking hook 41 extends towards the movable outer cover slide rail 30; both the elastic member 43 and the electrical component 44 act on the first end 45 of the locking hook 41; when the electromagnetic locking device 40 is in the locking state, the elastic member 43 acts on the first end 45 of the locking hook 41 to make the second end 46 of the locking hook 41 close to the locking groove 31; when the electromagnetic locking device 40 is in the unlocking state, the electrical component 44 acts on the first end 45 of the locking hook 41 to make the second end 46 of the locking hook 41 away from the locking groove 31. The elastic member 43 and the electrical component 44 cooperate with each other to realize the locking hook 41 of the electromagnetic locking device 40 approaching or leaving the locking groove 31, and further realize the switching between the locking state and the unlocking state. The electromagnetic locking device 40 has a simple structure and is convenient to use. In this embodiment, the housing 42 is a cube structure as a whole. The locking hook 41 is strip-shaped as a whole.

[0063] One end of the elastic member 43 is connected to the housing 42, and the other end of the elastic member 43 is connected to the first end 45 of the locking hook 41. The elastic member 43 applies a tensile force to the locking hook 41. The elastic member 43 applies a tensile force with a stable direction, and the tensile force can change with the change of the deformation amount of the elastic member 43, which can improve the stability of the locking hook 41 during movement and avoid excessive movement fluctuations of the locking hook 41. As an implementation manner, as Figure 4 and Figure 5 shown, the elastic member 43 can be a spring. In other embodiments, the elastic member 43 can also be an elastic sheet, an elastic rib band, a torsion spring provided between the pivot shaft 48 and the locking hook 41, etc.

[0064] One end of the electrical component 44 is fixedly arranged on the housing 42, and the other end of the electrical component 44 extends towards the first end 45 of the locking hook 41. The electrical component 44 applies a tensile force towards the electrical component 44 to the locking hook 41. The tensile force applied by the electrical component 44 to the locking hook 41 can be instantaneously changed, so as to improve the sensitivity of the locking hook 41, reduce the time during the movement of the locking hook 41, improve the locking or unlocking efficiency of the electromagnetic locking device 40, and improve the timeliness of the operation of the electromagnetic locking device 40.

[0065] The elastic member 43 and the electrical component 44 are arranged on two opposite side surfaces of the first end 45 of the locking hook 41. The elastic member 43 and the electrical component 44 respectively apply acting forces from two opposite side surfaces of the first end 45, so as to be able to mutually restrict the locking hook 41 and improve the flexibility and reliability of the movement of the locking hook 41.

[0066] The direction of the acting force applied by the elastic member 43 to the locking hook 41 and the direction of the acting force applied by the electrical component 44 to the locking hook 41 are on the same straight line.

[0067] The locking hook 41 further includes a mounting hole 47. The first end 45 and the second end 46 are respectively located on both sides of the mounting hole 47. The locking hook 41 is pivotally connected to the housing 42 through the mounting hole 47. The length of the second end 46 of the locking hook 41 is greater than the length of the first end 45 of the locking hook 41. The length of the second end 46 of the locking hook 41 is greater than the length of the first end 45 of the locking hook 41, so that the second end 46 can generate a greater lever arm relative to the pivot shaft 48. Furthermore, in the natural state, the second end 46 will have a tendency to rotate downward around the pivot shaft 48, and this tendency can make the locking hook 41 approach the locking groove 31, can prevent the locking hook 41 from accidentally moving away from the locking groove 31, and can improve the safety of the reverse pushing device 100.

[0068] The second end 46 of the locking hook 41 includes an extension section 461 and a downward folding section 462. The extension section 461 extends along the direction of the first end 45, and the downward folding section 462 extends from the extension section 461 in the direction towards the moving outer cover slide rail 30. The downward folding section 462 can further increase the weight of the second end 46, further driving the second end 46 to have a tendency to rotate downward. This tendency can make the locking hook 41 approach the locking groove 31, can prevent the locking hook 41 from accidentally moving away from the locking groove 31, and can improve the safety of the reverse pushing device 100. The downward folding section 462 can also hook the side surface of the moving outer cover slide rail 30, and can further prevent the locking hook 41 from accidentally moving away from the locking groove 31, improving the safety of the reverse pushing device 100. As an implementation manner, the included angle between the downward folding section 462 and the second end 46 can be 90°. In other embodiments, the included angle between the downward folding section 462 and the second end 46 can also be one of 30°, 45°, and 60°.

[0069] The electromagnetic locking device 40 is provided on the side of the locking beam 20 away from the moving outer cover slide rail 30. The locking hook 41 passes through the locking beam 20 and is clamped in the locking groove 31, which can prevent the electromagnetic locking device 40 from interfering with the movement of the moving outer cover slide rail 30 and can improve the safety of the movement process of the moving outer cover slide rail 30.

[0070] The locking beam 20 is provided with a through hole 21, and the locking hook 41 is inserted into the through hole 21, making the relative position between the electromagnetic locking device 40 and the locking beam 20 more flexible and also capable of improving the structural compactness of the reverse pushing device 100.

[0071] The moving outer cover slide rail 30 is provided with an extension plate 32. The side surface of the extension plate 32 is parallel to the extension direction of the locking beam 20, and the locking groove 31 is provided on the top surface of the extension plate 32. By providing the locking groove 31 on the top surface of the extension plate 32, it is convenient to adjust the depth of the locking groove 31, so as to facilitate adapting to the movement of the locking hook 41, can reduce the precision requirements for the installation of the electromagnetic locking device 40, and can also improve the tightness of the cooperation between the locking hook 41 and the locking groove 31, improving the safety and reliability of the reverse pushing device 100.

[0072] The latch beam 20 is provided with a sliding groove 22, and the sliding groove 22 extends inward from the side surface of the latch beam 20; the moving outer cover slide rail 30 has an insertion section 33, and the insertion section 33 is clamped in the sliding groove 22. The sliding groove 22 extends inward from the side surface of the latch beam 20, which can improve the structural compactness of the latch beam 20. The insertion section 33 moves in the sliding groove 22, which can improve the stability of the moving outer cover slide rail 30 during the moving process. As an implementation manner, the cross-sectional shape of the sliding groove 22 can be triangular, the tip of the triangle faces the outer side surface of the latch beam 20, and the bottom edge of the triangle faces the inner side of the latch beam 20. The two side edges of the triangle can be arc edges, and the arc edges can further improve the stability of the outer cover slide rail 30 during the moving process. The insertion section 33 is correspondingly arranged with the triangular sliding groove 22, and the insertion section 33 can be integrally in a "Y" shape. The two branches at the upper end of the "Y" shape are arranged in the sliding groove 22, and the side surfaces of the two branches at the upper end are attached to the side surfaces of the sliding groove 22. One branch at the lower end of the "Y" shape extends in a direction away from the sliding groove 22.

[0073] As an implementation manner, the electrical component 44 can include a solenoid valve, an electrical plug, a corresponding control switch, a power cord, etc. The electrical plug is used to connect the power cord for power excitation. Under the control of the control switch, the power cord provides power for the solenoid valve through the electrical plug. The solenoid valve can generate a magnetic force, and this magnetic force can generate a magnetic suction force on the locking hook 41 to realize the control of the locking hook 41.

[0074] The housing 42 of the electromagnetic locking device 40 further includes a mounting plate 421. The mounting plate 421 is provided with bolt holes, and bolts and nuts can be inserted into the bolt holes to mount the electromagnetic locking device 40 onto the latch beam 20.

[0075] As an implementation manner, the working state of the anti-pushing device 100 can be as follows.

[0076] In the case of no power excitation, the locking hook 41 is under the action of the pulling force of the elastic member 43, and the locking hook 41 tightly clamps in the locking groove 31 of the moving outer cover slide rail 30, thereby locking and limiting the moving outer cover slide rail 30, and further preventing the movement of the moving outer cover.

[0077] When the electromagnetic locking device 40 receives power excitation, the solenoid valve attracts the first end 45 of the locking hook 41, thereby driving the locking hook 41 to rotate counterclockwise around the pivot shaft 48. When the solenoid valve and the first end 45 of the locking hook 41 are completely attracted, the second end 46 of the locking hook 41 completely leaves the locking groove 31 and no longer limits the moving outer cover slide rail 30, so that the moving outer cover can move freely.

[0078] When the power excitation of the electromagnetic locking device 40 is withdrawn, the solenoid valve no longer attracts the first end 45 of the locking hook 41, and the locking hook 41 rotates clockwise around the pivot shaft 48 under the action of the spring tension, so that the second end 46 of the locking hook 41 is engaged with the locking groove 31 again, realizing the locking of the movable outer cover.

[0079] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present invention is defined by the appended claims. Without departing from the principle and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
