Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cable holding structure for connecting two devices, at least one of which is displaceable.

[0002] The present invention also relates to an aircraft control device provided with a control unit provided on the side of a pilot's seat, and more particularly to a structure for holding an electric cable for connecting the control unit and a flight control device.

[0003]

2. Description of the Related Art Fly-by-wire (Fly By Wire) systems are often used in aircraft, such as helicopters, as a control system. As a result, aircraft are placed on the sides of the seat where the pilot is seated. Many electric and electronic devices such as a control unit to be provided are mounted. The devices are connected by an electric cable and can transmit and receive signals to and from each other, so that the pilot can operate the stick provided on the control unit to control the aircraft.

[0004] Since the electric cable connecting each device is flexible, it is fixed to the floor and walls of the body using a clamp or the like, and is displaced by an inertial force accompanying vibration and acceleration / deceleration. Has been prevented. This prevents the electric cable from coming into contact with the equipment installed in the vicinity, and prevents the equipment and the electric cable itself from being damaged.

[0005]

Normally, since each device is fixedly installed and does not displace, there is no problem by fixing the electric cable connecting each device. However, it is conceivable to provide one of the devices, for example, a steering unit, so as to be displaceable in order to improve the convenience, but in order to allow the displacement of the device in this way,
It is necessary to be able to flex without fixing the electric cable. In particular, in order to increase the displacement of the device, the electric cable needs to have a long flexible portion. As described above, when the electric cable is allowed to bend freely, a portion locally curved with a radius of curvature smaller than the minimum bending radius specified for the electric cable is generated. If such bending occurs repeatedly, the life of the electric cable may be extremely shortened.

In view of the above-mentioned vibration and inertia caused by acceleration / deceleration, it is not preferable that the electric cable has a flexible portion. Further, when a plurality of electric cables are juxtaposed and juxtaposed, the electric cables may interfere with each other, which may hinder smooth displacement of the device.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cable capable of holding a connection cable connecting two devices while permitting displacement of at least one device so as to prevent undesired displacement of the connection cable. The purpose is to provide a retaining structure.

Another object of the present invention is to provide a connecting cable for connecting at least one of the two devices in which at least one of the devices is displaceable so that undesired displacement of the connecting cable can be prevented. It is to provide an aircraft control device that can be held.

[0009]

SUMMARY OF THE INVENTION According to the present invention, at least one device is provided so as to be displaceable, and two devices are connected by a flexible connecting cable, and are formed around an axis perpendicular to a predetermined virtual plane. The cable holding structure is characterized in that the connection cable is connected to a moving table that moves while being guided by a displaceable rail.

According to the present invention, at least one device is provided so as to be displaceable and has convenience, and in order to allow the device to be displaced, two devices are connected by a flexible connection cable. You. A predetermined position of the connection cable is fixed to the moving table, the displacement of the moving table prevents large bending near a predetermined position where the connection cable is connected to the moving table, and the displacement of the predetermined position is predetermined. Displacement can be allowed in a state limited within the virtual plane. As a result, even if the device is displaced along a virtual plane instead of in a straight line direction, the connection cable is prevented from being entirely displaced in a direction in which a predetermined position intersects a predetermined plane. Undesirable displacement is prevented by the vibration of the airframe provided and the inertial force due to acceleration / deceleration.

In particular, when two devices are connected by a plurality of connection cables, the connection cables are arranged adjacent to each other, but the connection cables interfere with each other. Is prevented.

In the present invention, the connection cable includes an electric cable used for supplying electric power and transmitting and receiving signals, and a hydraulic hose used for supplying and discharging hydraulic oil.

The present invention provides a control input unit which is provided standing up at a control position beside a seat on which a pilot sits, and which is operated by the pilot, a sensor which detects control information provided to the control input unit, and A control unit for controlling an aircraft, the control unit including a housing in which a feel means for providing a control feel to a control input unit is provided, the control unit being displaceably provided between the control position and a retreat position retracted from the control position. A control unit, a flight control device for communicating with the control unit and processing control information,
Curved in the shape of a letter, a plurality of electric cables for electrically connecting the control unit and the flight control device, a guide rail fixed to the fuselage and extending in a predetermined direction, and a plurality of balls rollably held, A flight control device for an aircraft, wherein a predetermined position of a substantially linear portion connected to a moving device of each electric cable is commonly connected and provided movably along a guide rail via each ball. is there.

According to the present invention, the steering unit is provided upright at a steering position beside the seat, and the pilot sits on the seat and operates the steering input unit in a posture that does not burden the body. Operate and input steering information. Furthermore, since the flight control unit and the flight control device are connected by an electric cable, the flight control device can process the input flight information. With this, the pilot operates the pilot input unit and inputs pilot information,
Can control the aircraft.

Further, the control unit can be displaced between the control position and the retreat position, whereby the control unit can be displaced to the retreat position as required, for example, when getting on or off the aircraft. Therefore, when the pilot sits on the seat or leaves the seat, he or she displaces the pilot unit to obtain a large space for movement, and the pilot device interferes with the pilot's feet etc. Can be prevented.

The flight control unit and the flight control device that can be displaced in this way are connected by a flexible electric cable, and the displacement of the flight unit is allowed by bending the connection cable. This electric cable is fixed to a movable table at a predetermined position where the electric cable is necessarily displaced by the steering unit, and is displaced along the rail by the displacement of the movable table. As a result, the electric cable is prevented from being entirely displaced in such a manner that the predetermined position is displaced in the remaining direction except for the movement path along the rail, and the electric cable is undesirably displaced due to the inertia force caused by the vibration and acceleration / deceleration of the aircraft body. Is prevented. In addition, the moving table holds a plurality of balls so as to roll freely, and each ball is interposed between the rails so as to be freely movable on the rails, so that the moving table is precise only in the direction along the rails. And each electric cable can move smoothly with a small force. Therefore, a force in the direction of angularly displacing the moving table with respect to the rail acts on the moving table from each electric cable, and the moving table is in a state of being bitten with respect to the rail, thereby preventing smooth displacement of the moving table. Never. That is, the displacement of each electric cable accompanying the displacement of the device is smooth, and the displacement operation of the device can be smooth. For example, even in the case where the pilot escapes in an emergency, the device can be smoothly displaced. . In addition, the moving table is prevented from vibrating in the direction different from the longitudinal direction of the rail with respect to the rail due to the vibration of the airframe, and the moving table and the rail are damaged even if installed on an aircraft where vibration is likely to occur. So as not to,
Each electrical cable can be guided over a long period.

Further, the predetermined position of the electric cable is guided only in the direction along the rail, and the electric cable is arranged at a position which does not hinder the seating operation of the pilot on the seat and the standing operation from the seat as described above. be able to. This does not impair the effect of making the steering unit variable. As described above, aircraft have many precision devices mounted adjacent to a narrow space, and high reliability of these devices is required to ensure the high safety of those precision devices. It is important to retain the cables connecting the flight control unit and the flight control equipment.

Further, in an aircraft, since it is necessary to transmit and receive signals representing a large amount of information with high reliability, a plurality of electric cables are required, and the diameter of each electric cable may be large. In such a case, the electric cables are arranged adjacent to each other, and the electric cables are less likely to bend. On the other hand, since each electric cable is commonly connected to one moving table only at a predetermined position, it is possible to prevent the electric cables from being individually displaced and interfering with each other. Moreover, since the displacement of each electric cable is restricted only at a predetermined position, it becomes thick as described above,
Even an electric cable used in an aircraft that is difficult to bend and, conversely, difficult to restrain displacement, can be smoothly guided in a state where the displacement direction is specified.

As described above, each electric cable 102 is arranged so as to have two substantially linear portions extending substantially parallel to the movement direction A and a curved portion that curves and connects the substantially linear portions. In a state where the linear portion is fixed to the moving table 103, one substantially linear portion is disposed so as to be displaced in parallel with the displacement direction A in accordance with the displacement of the one device 101. As a result, even if each electric cable 102 is displaced in accordance with the displacement of one of the devices 101, the radius of curvature of the curved portion is kept substantially constant, so that each electric cable 102 bends with a radius of curvature smaller than the specified minimum bend radius.

The stick 15 is provided near the front of the upper part of the housing 16 so that the pilot 13 sits on the seat 11 and does not burden the body. The stick 15 can be gripped and operated.

On the right side of the seat 11 near the rear,
The bracket 30 is fixed.
A hinge pin 31 having an axis L1 extending in the vertical direction is formed. The control unit 101 of the control device 10 includes:
A hinge pin 31 is inserted into a rear portion of the housing 16 which becomes the rear end portion 26 of the control unit 101, and the hinge pin 30 is provided on the seat 11 so as to be angularly displaceable about the axis L1 around the hinge pin 30. A latch box 33 is provided at a front portion of the housing 16 which is a front end portion 25 of the control unit 101, and an engagement protrusion 34 is formed at a right side near the front of the seat 11 to form a horizontal support portion. A bracket 35 having 36 is fixed.

As described above, the control unit 101 is connected by the hinge means, and the control position 20 shown in FIG. 7 and the retreat position shown in FIG. 8 in which the front end 25 is retreated from the control position 20 in the direction away from the seat 11. 21 is provided so as to be displaceable.

In front of the seat 11, near the floor 12, for example, a pair of control pedals 45a, 45b for operating and controlling the direction of the nose is provided. By operating each of the steering pedals 45a and 45b individually, the pitch of the tail rotor is controlled, and the aircraft is steered so that the nose turns left or right.

Further, in the cockpit, seats 11
A seat 50 for, for example, a co-pilot to be seated is provided adjacent to the vehicle, and an instrument panel 51 provided in front of the seat 11 is provided with instruments for displaying a flight state of the fuselage and surrounding conditions. Provided. A center pole 52 and side posts 53a and 53b are provided between the seats 11 and 50 and on the sides. As described above, the cockpit is provided with many devices and body components such as devices necessary for operating the body. Therefore, the space for the pilot 13 to move in the cockpit is small, and the pilot unit 101,
As a result, the control device 10 may be in the way. For example, as shown in FIG. 9, when the user gets on and off from an entrance 56 formed by opening a door 55 provided on the side of the seat 11, the seat from the side where the control unit 101 is provided (right side in this embodiment). If the control unit 101 remains fixed at the control position 20 when the user sits on the seat 11 or separates from the seat 11, the control unit 101 interferes with a foot or the like as described above.

On the other hand, in the control device 10 of the present embodiment,
The control unit 101 is provided so as to be displaceable between a control position 20 and a retreat position 21 retracted from the control position 20,
Thus, the pilot 13 can displace the control unit 101 to the retreat position 21 as necessary, and can obtain a wide space beside the seat 11. Moreover, in the present embodiment, the front end portion 25 of the control unit 101 is displaced rearward, so that a wide space can be obtained on the side of the seat 11 closer to the front. In addition, the pilot 13, while sitting on the seat 11, grips the vicinity of the front end 25 of the control unit 101, and angularly displaces the arm in the left-right direction about the elbow or the shoulder, to thereby control the control unit. 101 can be easily angularly displaced.

Therefore, the pilot 13 displaces the control unit 101 to the retreat position 21 when getting on and off, to obtain a large space for the pilot 13 to move in the cockpit, and to make the pilot's 13 feet or the like. And the control unit 10
1 can be prevented from interfering, and the user can easily sit on the seat 11 or separate from the seat. In particular, even in the case of escape from the cockpit to the outside of the aircraft in an emergency, the escape can be performed quickly and safely. In addition, it is possible to avoid damage to the control device 10 which is a precision machine, in particular, the stick 15 protruding from the housing 16. Further, since the control unit 101 can be angularly displaced between the control position 20 and the retreat position 21, the maintainability of the control unit 101 is improved. When the hinge pin 31 is used, for example, the hinge pin 31 can be easily removed from the seat 11 by extracting the hinge pin 31, thereby further improving the maintainability.

Further, when the control unit 101 is at the control position 20, the front end portion 25 has the latch box 33.
The steering unit 101 is locked to the seat 11 by the locking means including the engaging projections 34, so that the steering unit 101 is not moved undesirably due to, for example, vibration during flight. 20. Therefore, there is no danger that the maneuverability is impaired, and there is no possibility of causing a failure. Further, since the steering unit 101 is connected to the seat 11 by hinge means having hinge pins 31, an angular displacement mechanism for retracting the steering unit 101 can be realized at low cost. Further, also for the latch box 33, it is possible to use a latch mechanism provided for a door of a four-wheeled motor vehicle, which is easily available commercially, and is easy to manufacture.

As described above, the connection position of each electric cable 120 is displaced forward by the angular displacement of the control unit 101 between the control position 20 and the retreat position 21. On the other hand, each electric cable 102 is guided by the moving table 103, and the predetermined position sandwiched by the clamps 116 is displaced back and forth. Thus, similarly to the case shown in FIGS. 1 to 4, each electric cable 102 can be guided with respect to the displacement of the control unit 101, and the same effect can be achieved.

Each electric cable 102 is held behind the seat 13 which does not hinder the operation, sitting on the seat 11 and standing up from the seat 11, so that the pilot 13 as described above is used. The steering unit 1 is disposed at a position where it does not interfere with the seating and standing motion of the
The effect of making 01 variable is not hindered. The aircraft has many precision instruments mounted adjacent to a small space and requires high reliability of these instruments in order to ensure high security. The importance of the connection structure between the control device 100 and another control device 100 is high.

Further, in an airplane, since it is necessary to transmit and receive a signal representing a lot of information with high reliability, a plurality of electric cables 102 are required. Therefore, the configuration is important to prevent mutual interference. Each electric cable 102
Is large, for example, about φ20 to φ30 mm, has high rigidity and is hard to bend, and a large force acts on the moving table 103 from each electric cable 102 in the direction of angular displacement with respect to the rail 109. As described above, it is important to use a slide guide having the moving table 103 and the rail 109 having a precise configuration as described above. This makes it possible to prevent the smooth displacement of the control unit 101 from being hindered.

Each of the linear sliders 60a and 60b is fixed to the side of the seat 11 with a vertical space therebetween and a pair of guide rails 61a and 61b, and is fixed to the housing 16 and is movable to the guide rails 61a and 61b. It has moving pieces 62a and 62b to be fitted. Each guide rail 61
a, 61b are provided extending in the front-rear direction, and the control unit 101 moves the guide rails 61a, 61 from the control position 20.
It can be slid rearward along the position b toward the retreat position 21a.

A latch box 33a is provided near the front end 25 of the control unit 101, and an engagement projection 34a is provided on the right side of the seat 11 near the front.

The steering device 10a can also provide a large space on the front side of the seat 11, similarly to the steering device 10 of the above-described embodiment. Further, the pilot 13 can easily slide and displace the control unit 101 by displacing the arm in the front-rear direction, for example, by gripping the vicinity of the front end of the control unit 101 while sitting on the seat 11. Thus, the same effect as that of the control device 10 can be obtained. Also, the control unit 101
Each linear slider 60a, 60b for connecting
It is readily available commercially and is as easy to manufacture as when using hinge pins 31. In such a control device 10a, the same effect can be achieved by guiding each electric cable 102 back and forth.

FIG. 11 is a perspective view showing a part of a steering device 10b according to still another embodiment of the present invention. The control device 10b has a configuration similar to that of the control device 10 of the above-described embodiment.

As described above, according to the cable holding structure of the present invention, the predetermined position of the connection cable can be guided and held so that it can move only within a predetermined virtual plane with respect to the displacement of the device. As a result, undesired displacement due to vibration of the body and inertial force due to acceleration / deceleration can be prevented. In addition, the connection cable can be angularly displaced about an axis perpendicular to the virtual plane at a predetermined position, and in a state where a large bending force is prevented from being applied to the connection cable, the displacement of the device along the virtual plane is allowed. , Each device can be connected,
It is possible to prevent the connection cable from bending at a small radius of curvature and causing contact with peripheral devices, which may cause damage.

According to the control device of the present invention, the control unit can be displaced between the control position and the retreat position.
A wide space can be obtained beside the seat. In addition, the steering unit can be easily displaced while sitting on the seat. Therefore, it is possible to easily sit on the seat or leave the seat without causing the pilot device to interfere with the pilot's feet or the like. In particular, even in the case of escape from the cockpit to the outside of the aircraft in an emergency, the escape can be performed quickly and safely. In addition, it is possible to avoid damage to the control device, which is a precision machine. Further, since the steering unit can be angularly displaced between the predetermined position and the retracted position, the maintainability of the steering unit and thus the steering device is improved.

Further, the electric cable can be held so as to be guided only in the direction along the rail with respect to the displacement of the control unit, and it is possible to prevent undesired displacement due to vibration of the body and inertial force due to acceleration / deceleration. It is. Therefore, the displacement of the control unit can be allowed, the control unit and the flight control device can be connected, and the bending of the connection cable and the contact with the peripheral device, which can cause damage, can be prevented. Furthermore, the moving table is provided movably on the rail with a plurality of balls interposed, and is guided precisely and smoothly only in the direction along the rail, and each electric cable can move smoothly with a small force. it can. Therefore, the displacement of each electric cable accompanying the displacement of the control unit is smooth, and the displacement operation of the device can be smooth. For example, even when the pilot is in an emergency escape, the device can be smoothly displaced. it can. In addition, the moving table is prevented from vibrating in the direction different from the longitudinal direction of the rail with respect to the rail due to the vibration of the airframe, and the moving table and the rail are damaged even if installed on an aircraft where vibration is likely to occur. Each electrical cable can be guided over a long period of time so that it does not. Further, since each electric cable is commonly connected to one moving table only at a predetermined position, it is possible to prevent the electric cables from being individually displaced and interfering with each other. In addition, since the displacement of each electric cable is restricted only at a predetermined position, the electric cable is thick as described above, is not easily bent, and conversely, even if it is an electric cable used in an aircraft that is difficult to restrict the displacement, the displacement direction is not changed. Can be smoothly guided in a state in which is specified.
