Description

Cable guide device

Technical Field

The invention relates to a cable guide device used in the field of aircraft, in particular to a device for guiding flexible cables between a slat and a fixed leading edge of a civil aircraft.

Background

A large number of sensors are provided in the slat section of an aircraft. These sensors typically require connection to a fixed leading edge by a flexible cable. However, during takeoff, flight and landing of an aircraft, there is relative motion between the slat and the fixed leading edge. When the slat is lowered, the flexible cables between the slat and the fixed leading edge may be exposed in the gap formed by the lowered slat. In this case, if there is no corresponding supporting fixture for the cables to guide their course, the cables are likely to become lodged in the gap between the slat and the fixed leading edge, impeding slat movement. Furthermore, the space in the stationary leading edge is small, and the cables of the system are numerous, and therefore the layout environment is complicated.

For this purpose, US 9187171B 2 (published: 11/17/2015) proposes a cable guide device on a wing, in which a crank-slider mechanism is used, a link is connected to a slat with a sleeve, a crank is connected to a fixed leading edge with a hinge, and the link and the crank are connected by a hinge. In the process of folding and unfolding the slat, a crank on the fixed leading edge can rotate around a shaft in a plane vertical to the wing surface of the wing, so that a connecting rod on the slat is pushed to move along the direction of the sleeve, and a cable between the slat and the fixed leading edge is guided to be folded and unfolded. However, the contact length between the connecting rod and the sleeve in the crank-slider mechanism is long, and the fit clearance between the connecting rod and the sleeve can cause errors in the motion track of the connecting rod, and can affect the normal winding and unwinding of the cable at the slot end in serious cases. Furthermore, during telescopic guidance, the flexible cable tends to fold sharply and bend over a small range, causing the cable to become tangled.

CN 104426113 a (published: 2015, 3/18) proposes a cable guide device on a wing, in which a double rocker mechanism is provided, and a single rocker is hinged to both the slat and the fixed leading edge. The rocker arms are also connected with each other through hinges. In the process of folding and unfolding the slat, the double rocker arms can rotate around each connecting point, the posture of the mechanism is continuously adjusted, the change of the distance between the adaptive slat and the fixed leading edge is kept, and the cable between the slat and the fixed leading edge is guided to be folded and unfolded. However, the use of a dual rocker mechanism requires a large amount of space within the fixed leading edge, which can affect the placement of other components within the fixed leading edge.

In WO 2015/069127 a1 (published: 2015, 5/14), a multidirectional cable guide is proposed, comprising a linear cable holder and an arched cable holder, wherein a detachably mounted cable guide cover and a platform are provided. The device supports cable guidance in multiple directions, the interior of the brackets being connected by bolted sliding rails, so that the sliding rails, although adjustable in orientation relative to each other, cannot slide relative to each other. Such devices are not suitable for use in aircraft wings. In addition, the detachably mounted cable leading-out cover plate and the platform need manual operation, so that the detachable cable leading-out cover plate is not suitable for the aerial cable winding and unwinding operation in the flying process.

In CN 104185934 a (published: 2014 12/3), a cable guiding device on a wing is proposed, comprising a base and a movable member, the movable member comprising a resilient pad. The movable member is filled by the elastic deformability of the elastic cushion, thereby defining a gap of the support, keeping the cable bound. However, the ability of the resilient pads to deform can only compensate for a small range of gaps within the device and is not sufficient to support the large scale spacing changes caused by slat retraction.

An arm type motion cable mechanism including a slider-crank mechanism is known from CN 110641682 a (published: 1/3/2020) in the name of the same applicant. The slat is connected to the connecting rod by a sleeve, the fixed leading edge is connected to the crank by a hinge, and the connecting rod and the crank are connected by a hinge. In the process of folding and unfolding the slat, a crank on the fixed leading edge can rotate around a shaft in a plane parallel to the wing surface of the wing, so that a connecting rod on the slat is pushed to move along the direction of the sleeve, and a cable between the slat and the fixed leading edge is guided to be folded and unfolded. However, as described above, the movement in the slider-crank mechanism may cause an error in the movement locus of the connecting rod.

Accordingly, there remains a need in the art for a cable guide arrangement that is further improved with respect to the above mechanisms or arrangements, is simple in construction, easy to install, and takes up less space, thereby providing guiding support for the flexible cable between the slat and the fixed leading edge.

Disclosure of Invention

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a cable guide device that can guide a flexible cable arranged between a slat and a fixed leading edge of a civil aircraft, and that can prevent the flexible cable from being caught in a gap between the slat and the fixed leading edge and affecting the retraction of the slat.

Another object of the present invention is to provide a device for guiding a flexible cable of an aircraft, which prevents the flexible cable from winding around itself, thereby causing damage to the cable.

It is also an object of the invention to propose a device for guiding a flexible cable of an aircraft which takes up less installation space and leaves more space for the installation of other devices in the fixed leading edge.

The above object is solved by a cable guide for an aircraft, comprising:

a guide section for guiding the flexible cable from a slat to a fixed leading edge of an aircraft,

wherein the guiding section is configured to be telescopic in height and length directions,

wherein the guide section is pivotally connected at a first end to a rear cavity bulkhead of a slat of the aircraft and at a second end to a fixed leading edge of the aircraft,

wherein when the slat is lowered, the guide section is in an extended state with the flexible cable extending out of the fixed leading edge, and when the slat is stowed, the guide section is in a retracted state with the flexible cable retracted into the fixed leading edge.

Thus, during slat deployment and deployment, the cable guide arrangement according to the invention provides support for flexible cables between the slat and the fixed leading edge, guiding these cables to be safely deployed and deployed with the slat.

The flexible cable is ideally arranged to extend along the course of the guide section of the cable guide and is fixed to the guide section by means of at least one flexible fixing device. Therefore, the cable guide device can limit the trend of the flexible cable to a certain extent, and prevent the overlong flexible cable section from freely rotating, so that the motion track of the slat is not controlled during the folding and unfolding.

It is particularly desirable for the flexible cable to be completely fixed on the guide section by means of a plurality of flexible fixing means. This can prevent that flexible cable from folding crooked and entangling each other, has improved the security of cable, guarantees again simultaneously between a plurality of sections of cable, or can not take place relative motion between each cable under the circumstances of many cables, the surperficial friction loss of cable that has significantly reduced realizes the protection to flexible cable. Here, a "section" of the flexible cable is understood to be a portion of the flexible cable which is constrained at both ends by the flexible fixation means.

Optionally, the flexible fixing device is a clip.

In particular, the guide section of the cable guide comprises a truss structure formed by at least four links. The truss structure includes at least one rhombus-shaped unit, and the at least four links are rotatably connected with respect to each other.

The truss structure is capable of collapsing in both the overall length and width directions. The height of the truss structure is the shortest, for example when the length of the truss structure is the longest, for example corresponding to a situation in which the slat is lowered. Conversely, when the length of the truss structure is shortest, for example corresponding to a stowed condition of the slat, the height of the truss structure is highest, at which point it is almost fully retracted into the fixed leading edge. In addition, the truss structure can achieve a large amount of telescoping in the horizontal direction.

The structural stability of the guide section in the form of a truss ensures the reliability of the movement of the guide section during extension and retraction. Furthermore, the guide section, as described above, is able to accommodate large displacements of the slat relative to the fixed leading edge of the aircraft in the horizontal direction with small displacements in the vertical direction, and it occupies little space within the fixed leading edge, facilitating the design and arrangement of other components within the fixed leading edge.

In particular, at least four links of the truss structure are hingedly connected to each other at the ends or at the middle portion by means of hinges. Here, the middle portion refers to a portion within +/-5% of the length at and near the midpoint of the link.

Preferably, the guide section comprises more than two diamond-shaped cells, i.e. it comprises at least six links.

One end of the guide section is connected to the rear cavity bulkhead of the slat by a hinged connection, while the other end extends into the fixed leading edge, the other end comprising at least two parts, one part being connected to the fixed leading edge also by a hinged connection, and the other part being slidably connected to the fixed leading edge.

Ideally, the sliding connection is achieved by a slider and a sliding chute, and the curved shape of the sliding chute is designed to conform to the motion trajectory of slat deployment and retraction. This prevents the runner from becoming disengaged from the slider sliding therein, and prevents the truss structure of the guide section from being prematurely damaged by excessive restraint reaction forces.

Preferably, the slider is a rolling slider. Particularly preferably, the roller slide is spherical. The abrasion and the blocking of the ball head in the sliding rail can be effectively reduced, and meanwhile, the efficiency and the service life of the sliding connection part are improved. In addition, the high constraint precision can be realized through the cooperation of slider and spout.

The cable guide device provided by the invention has the advantages of light weight, small occupied space, good installation and maintenance performance, high movement reliability and the like. The structure is simple, the requirement on materials is low, and the processing, the installation and the maintenance are convenient.

Additional features and advantages of the invention described herein will be set forth in the detailed description which follows, and in part will be readily apparent to those skilled in the art from that description or recognized by practicing the embodiments described herein, including the detailed description which follows, the claims, as well as the appended drawings.

Detailed Description

Reference will now be made in detail to various embodiments of the invention, examples of which are illustrated in the accompanying drawings and described below. While the invention will be described in conjunction with the exemplary embodiments, it will be understood that this description is not intended to limit the invention to those exemplary embodiments. On the contrary, the invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims. For convenience in explanation and accurate definition in the appended claims, the terms "upper", "lower", "inner" and "outer" are used to describe features of the exemplary embodiments with reference to the positions of such features as displayed in the figures.

A cable guide device generally given the reference numeral 1 is described below with reference to fig. 1.

The cable guide device 1 is arranged between a slat rear cavity bulkhead 100 and a fixed leading edge 200 of an aircraft.

The cable guide 1 has a guide section 10 which is telescopic in the transverse direction and in the longitudinal direction. Preferably, as shown, the guide section 10 is in the form of a truss structure. The guide section 10 will be explained in more detail below with reference to fig. 4.

The guide section 10 has a first end 101 and a second end 102. The first end 101 is the end of the guide section 10 on the left in the figure. The first end 101 is connected to the slat rear cavity bulkhead 100 by a first hinged connection 20. The second end 102 is the end of the guide section 10 on the right in the figure. As can be seen in fig. 1 and will be explained in more detail below with reference to fig. 4, the second end 102 of the guiding section 10 in a truss structure has an upper portion 1021 and a lower portion 1022, both connected to the fixed leading edge 200, wherein the upper portion 1021 of the second end 102 is slidably connected to the fixed leading edge 200 by means of the sliding connection 40, and the lower portion 1022 of the second end 102 is rotatably connected to the fixed leading edge 200 by means of the second hinge connection 30. The first hinge connection 20, the second hinge connection 30 and the sliding connection 40 will be further explained with reference to fig. 6 to 8C.

As can be seen, the flexible cable 6 for the sensor provided on the wing passes through an opening (not visible in fig. 1) made in the slat rear cavity bulkhead 100 and is fixed to the links constituting the guide section 10 at a number of points on the guide section 10, so that the flexible cable 6 runs substantially along the links on the guide section 10 and finally to the second end 102 of the guide section 10.

It can be noted in fig. 1 that the guide section 10 in the form of a truss comprises shorter and longer links. On the shorter link the flexible cable 6 is fixed to the link at three places, and on the longer link the flexible cable 6 is fixed to the longer link at six places, respectively. It should be noted, however, that the above-mentioned fixed number is merely illustrative and not restrictive. The number of attachment points of the flexible cable 6 to each link can be correspondingly greater or smaller, provided that the course of the flexible cable 6 in the guide section 10 follows the direction of extension of the links as much as possible without deviating from the diamond-shaped space between the links in which the links hang. In other words, in the case of the guide section 10 shown in fig. 1 in the form of a truss of diamond-shaped cells, the course of the flexible cable 6 should follow the sides of the diamond-shaped cells and should not pass through the middle of any diamond-shaped cell. The purpose of this is to ensure that the flexible cable 6 moves with the guide section 10 as far as possible when the slat is lowered and stowed, avoiding that sections of the flexible cable 6 that are too long hang over, and then are uncontrolled in the movement of the slat, resulting in hindering the slat movement or causing the flexible cable of this longer free section to become entangled and thus causing damage to the cable.

Turning now to fig. 2 and 3. They show the guide section 10 of the cable guide device 1 in the extended state and in the retracted state, respectively. In these figures, the flexible cable 6 guided by the cable guide 1 is not shown for the sake of clarity.

Fig. 2 shows the slat in a lowered condition. At this time, the guide section 10 of the cable guide device 1 is in an extended state. Fig. 3 then shows the slat in a stowed condition. At this time, there is almost no gap between the slat and the fixed leading edge 200, and the guide section 10 of the cable guide device 1 assumes a retracted state.

The guide section 10 in the embodiment shown comprises three diamond-shaped cells. As can be seen by comparing fig. 2 and 3, when the guide section 10 is in the extended state, the height and width of each of the three diamond-shaped cells are closer, and the overall length of the guide section 10 is longer, while the height is lower. In contrast, when the guide section 10 is in the retracted state shown in fig. 3, its overall length is short and its height is increased, so that the space occupied by the cable guide device 1 is reduced overall. In this state, each of the diamond-shaped cell shapes inside the truss structure of the guide section 10 is relatively flat and has a large aspect ratio.

The first end 101 of the guide section 10 of the cable guide arrangement 1 is always hingedly connected to the slat aft cavity bulkhead 100 by a first hinged connection 20 explained in more detail below, while the second portion 1022 of the second end 102 is also always hingedly connected to the fixed leading edge 200 by a second hinged connection 30 during deployment and retraction of the slat relative to the fixed leading edge 200. In other words, the second portions 1022 of the first and second ends 101, 102 of the guide section 10, i.e. the lower portions shown in the drawings, are only able to rotate relative to, and not slide over, the slat aft cavity bulkhead 100 and the fixed leading edge 200 respectively, during slat lowering and stowing. In the process, the extension and retraction of the guide section 10 is carried by the first portion 101 of the second end 102 of the guide section 10 which is slidably connected to the fixed leading edge 200 relative to the fixed leading edge 200, in addition to the movement of the slat aft cavity bulkhead 100 towards and away from the fixed leading edge 200. This sliding connection 40 will be explained further below with the aid of fig. 8A to 8C.

Turning now to fig. 4. Fig. 4 shows the structure of the guide section 10 in detail.

The guide section 10 is of truss construction and comprises eight links 11 to 18, of which in the illustrated embodiment mainly two types of length links are involved. Both the first link 11 and the second link 12 are short in length, and are located on the left side in the drawing. First ends of the first and

second links

11, 12 are hingedly connected together and are pivotally connected to a slat rear cavity bulkhead 100 (not shown here) by a first hinged connection 20 (not shown here). The end of the first link 11 and the second link 12 hinged together corresponds to the first end 101 of the guide section 10.

The remaining six links 13 to 18 are longer in length. In one aspect, the first end of the third link 13 is connected to the second end of the first link 11 by a hinge 191, and the second end is connected to the first end of the sixth link 16 by a hinge 191, and the second end of the sixth link 16 is connected to the first end of the seventh link 17 by a hinge. The second end of the seventh link 17 corresponds then to a first section 1021 of the second end 102 of the guide section 10, to which a rolling slider 41 is connected for sliding connection to a fixed leading edge 200 (not shown here) by means of a sliding connection 40. On the other hand, similarly, the first end of the fourth link 14 is connected to the second end of the second link 12 by a hinge 191, and the second end of the fourth link is connected to the first end of the fifth link 15 by a hinge 191. The second end of the fifth link 15 is in turn similarly hinged to the first end of the eighth link 18. The second end of the eighth link 18, like the first end hinged together with the first link 11 and the second link 12, is pivotably connected to the fixed leading edge 200 by means of a hinged connection 30 (not shown here).

Here, it should be noted that, although only two are shown, the connection between the links employs hinges 191. In addition, as for the third to eighth links 13 to 18, in order to control the movement locus of the link pivoting, a third link is connected to the middle section of each link through a hinge 191 in addition to the two links to which the head and tail ends are connected. As shown, the third link 13 is connected at its mid-portion, preferably at a mid-point of the length, to a mid-point of the fourth link 14 by a hinge 191, crosswise to it. The fifth link 15 and the sixth link 16 are also rotatably connected to each other at their midpoints by a hinge 191. The seventh link 17 and the eighth link 18 are rotatably connected to each other at intermediate positions thereof by a hinge 191.

The telescopic guide section 10 of the cable guide 1 can thus also be regarded as three half-cross-shaped elements which are rotatable relative to one another and which are connected to one another at the ends to form a plurality of end-to-end rhombuses. The third to eighth links 13 to 18 can be pivoted about their two ends by means of a hinged connection at their two ends, so that the guide section 10 of the truss structure as a whole can be telescoped in the horizontal and vertical directions, its length and height being adjusted, which makes it possible for the cable guide 1 to have a large amount of horizontal extension in the horizontal direction, so that it is achieved that the cable guide 1 as a whole can be moved together with the slat relative to the fixed leading edge 200.

In addition, rivets 192 are further provided on both sides of each hinge 191 in order to prevent the link from being laterally dropped.

Turning next to fig. 5.

Fig. 5 shows a detail a of the guide section 10 to further illustrate the connection relationship between the links of the guide section 10 and the guiding of the flexible cable 6 by the guide section 10.

Fig. 5 shows the pivotal connection of the third link 13 to the sixth link 16. In the figure it can be seen that the pivotal connection is provided with a hinge 191, on both sides of which rivets 192 are provided for preventing the

links

13, 16 from falling out sideways. The flexible cable is guided to the fixed leading edge via the guide section 10 after it has been extended out of an opening in the slat rear cavity bulkhead 100.

As can be seen in fig. 5, the flexible cable 6 runs substantially along the extension of the link, in particular first along the third rail 13 to the second end and then turns at its hinged connection to the first end of the sixth link 16. The limitation of the orientation of the flexible cable 6 is performed by applying a clamp 193. As shown, the flex cable is provided with a clip 193 on each side of the end hinge of the links to ensure that the flex cable 6 is always retained on the truss structure without hanging in the diamond shaped cells when the third link 13 and the sixth link 16 are pivoted relative to each other. This latter situation may prevent the links from turning relative to each other the next time and cause the cable 6 to become jammed between the links, causing damage to the cable.

One or more clips 193 are provided on the main extension of the connecting rod, depending on the length of the connecting rod and the degree of flexibility of the flexible cable itself, to keep the flexible cable 6 as far as possible on the structure of the truss without loosening.

Thus, during slat lowering, the flexible cable 6 extends out of the fixed leading edge 200 as the guide section 10 extends out. When the slat is retracted, the flexible cable 6 is then retracted substantially fully into the fixed leading edge 200 as the guide section 10 is retracted.

The manner of connection between the cable guide device 1 and the slats of an aircraft and the fixed leading edge 200 is explained below in connection with fig. 6 to 8C, which show both ends 101 and 102 of the guide section 10.

In fig. 6, a first articulated connection 20 is shown where the guide section 10 of the cable guide 1 is located between a first end 101 on the left side of fig. 1 to 3 and the slat rear cavity bulkhead 100. As shown, the first ends of the first and

second links

11, 12 of the cable guide are hingedly connected together by a hinge 22 to a hinged connection mount 21, in particular to a mounting tab 211 mounted to the hinged connection mount, so that the cable guide 1, in particular the guide section 10 of the cable guide, can rotate relative to the slat.

The articulated mount 21 is here fixedly connected to the slat rear cavity bulkhead 100 by six bolts 23. At the base of the articulated connection mount 21, an opening 24 is provided, through which opening 24 the flexible cable 6 (not shown here) protrudes and, as described above, extends further along the guide section 10, is fixed to the connecting rod of the guide section 10 by fixing means, for example a clip 193, and finally reaches the fixing front edge 200.

Thus, as the slat moves relative to the fixed leading edge 200, i.e. towards or away from the fixed leading edge 200, the first end 101 of the guide section 10 moves with the slat, thereby achieving scalability of the guide section 10 in the length direction.

Fig. 7 and 8C each show the connection of the second end 102 of the guide section 10 of the cable guide device 1 to a fixed leading edge 200 of the aircraft.

In particular, fig. 7 shows an upper part 1021 and a lower part 1022 of the second end 102 of the guide section 10, where both the upper and

lower parts

1021 and 1022 are connected to a fixed leading edge 200 of the aircraft, wherein the upper part 1021 is slidably arranged on the fixed leading edge 200 relative to the fixed leading edge 200 by means of a sliding connection 40, while the lower part 1022 is pivotably connected to the fixed leading edge 200 by means of a second hinge connection 30.

The second hinge connection 30 is similar to the first hinge connection 20 described above in connection with fig. 6. The second end of the eighth link 18 of the cable guide 1 is connected by means of a hinge 32 to a mounting lug on a support 31 of the second articulated connection 30, while the support 31 is in turn connected fixedly to the fixed front edge 200 (not shown here) by means of a plurality of bolts. This enables the lower portion 1022 of the second end of the guide section 10 to undergo pivotal movement relative to the fixed leading edge 200 during slat lowering and stowage.

The upper part 1021 of the second end 102 of the guide section 10 is here in turn slidably connected to the fixed leading edge 200.

In particular, as already mentioned above in connection with fig. 4 when describing the truss-like structure of the guide section 10, the second end of the seventh link 17 of the guide section 10 is provided with a rolling slider 41 which can slide in a sliding slot 42. Fig. 8A-8C further illustrate this sliding connection between the cable guide device 1 and the fixed leading edge 200 of the aircraft.

The slide groove 42 is in the form of a curve having a certain curvature as a whole. The rolling slider 41 is spherical and is located in and movable along the slide groove 42. The chute 42 is fixedly attached to the fixed leading edge 200 of the aircraft by any known means.

The curve of the sliding groove 42 is designed to conform to the track of the slat retraction movement of the aircraft, so that the possibility of non-engagement between the rolling slider 41 and the sliding groove 42 is avoided, and therefore the rolling slider 41 is ensured to freely slide in the sliding groove 42 without being stuck therein, and further tensile acting force is generated on the upper part 1021 of the second end 102 of the guide section 10.

Fig. 8B and 8C further show the rolling slider 41 and the slide groove 42.

In the above embodiment, the case where the flexible cable 6 is fixed to the guide section 10 of the cable guide device 1 has been described, but the present invention is not limited thereto. In fact, the flexible cable may also be secured to the links of the guide section 10 by means of, for example, banding with restraining bands, or adhesive bonding.

Furthermore, in the above-described embodiment, the connection of the abutments 21 of the first hinge connection portion 20 to the rear wall barrier 100 of the slat and the abutments 31 of the second hinge connection portion 30 to the fixed leading edge 200 has been described as being a bolted fixed connection, but the invention is not limited thereto and the

abutments

21, 31 may be connected to the slat and the fixed leading edge by any other connection means known in the art, for example a fixed connection by means of screws or a fixed connection by means of welding.

Furthermore, the truss structure of the guide section, although in the embodiment shown in the present application it has a diamond shape, may also be designed according to the requirements of the specific cable, e.g. weight, length, cross section, etc. In particular, the truss structure may be designed as an equidistant truss, a non-equidistant truss, depending on the available space and the length requirements of the flex cable. And due to the influence of the weight and section requirement of the flexible cable on the rigidity and strength, the number and section of the truss structures can be designed according to the influence.

In the present invention, the embodiments may be freely combined, or may be appropriately modified or omitted within the scope of the present invention.
