Description

Technical Field

[0001] This application relates to the field of aircraft technology, and more specifically, to a folding mechanism for an aircraft and an aircraft. Background Technology

[0002] Currently, some ducted-duct drones are used for high-altitude firefighting. However, some ducted-duct drones are too large and inconvenient to transport. Therefore, it is necessary to design a corresponding folding mechanism to reduce the size of the ducted-duct drone. For example, application number CN202411736732.7 provides a ducted-duct drone structure, specifically disclosing a telescopic frame 5 including a frame 18, an electric push rod base 25 mounted on a rotating seat 24, one end of the electric push rod base 25 being hinged to the rotating seat 24, and the other end of the electric push rod base 25 being provided with a push rod body 26. The telescopic frame extends and retracts through two electric push rods, and the two electric push rods generate extension and retraction forces in different directions to realize the extension and retraction of the telescopic frame. However, when the two electric push rods are subjected to large loads for a long time, they are prone to becoming out of sync, and the telescopic frame is prone to failure. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a folding mechanism and an aircraft, wherein the telescopic component drives the first and second parts that can rotate synchronously, thereby reducing the risk of failure of the folding bracket.

[0004] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0005] In a first aspect, this application provides a folding mechanism for an aircraft, comprising: a folding bracket, one end of which is connected to a duct and the other end of which is connected to the fuselage of the aircraft; the folding bracket includes a first part and a second part that can rotate synchronously with each other; and a telescopic member, which is inclined and whose two ends are respectively hinged to two rods on the same side of the vertical direction of the first part, or; the two ends of the telescopic member are respectively hinged to two rods on the same side of the vertical direction of the second part; wherein, in the extended state, the telescopic member is used to drive the first part and the second part to rotate synchronously with each other, and the folding mechanism changes from an unfolded state to a folded state; in the shortened state, the telescopic member is used to drive the first part and the second part to rotate synchronously with each other, and the folding mechanism changes from a folded state to an unfolded state.

[0006] In one embodiment, the first split body includes a first rod and a second rod spaced apart, and the second split body includes a third rod and a fourth rod spaced apart. The first rod is drivenly connected to the third rod, and the second rod is drivenly connected to the fourth rod.

[0007] In one embodiment, one end of the first rod has a first tooth, one end of the second rod has a second tooth, one end of the third rod has a third tooth, and one end of the fourth rod has a fourth tooth. The first tooth meshes with the third tooth, and the second tooth meshes with the fourth tooth.

[0008] In one embodiment, the first tooth is located in a portion of the first rod, the second tooth is located in a portion of the second rod, the third tooth is located in a portion of the third rod, and the fourth tooth is located in a portion of the fourth rod.

[0009] In one embodiment, two meshing gears are provided between the second tooth and the fourth tooth, and the two gears mesh with the second tooth and the fourth tooth respectively.

[0010] In one embodiment, the folding mechanism further includes a support member, which is rotatably connected to the first tooth, the second tooth, the third tooth, the fourth tooth, and the two gears.

[0011] In one embodiment, the first split includes two first rods connected by a first connecting shaft; a locking element is provided on one side of the third rod, the locking element including a locking hook, the locking hook being used to connect with the first connecting shaft in the folded state of the folding mechanism.

[0012] In one embodiment, the folding mechanism further includes a driving member connected to the locking member for driving the locking member to rotate.

[0013] In one embodiment, the folding mechanism further includes a connector, which includes a protrusion and a main body connected to the protrusion. One end of the first rod is rotatably connected to the protrusion, and one end of the second rod is rotatably connected to the main body at the opposite end of the protrusion.

[0014] Secondly, this application provides an aircraft that includes the folding mechanism of the aircraft described in the first aspect.

[0015] The technical solution of this application has the following beneficial effects:

[0016] The folding mechanism includes a folding bracket, one end of which is connected to the duct and the other end to the aircraft fuselage. The folding bracket includes a first part and a second part that can rotate synchronously. Thus, when the first or second part is driven to rotate, the other part can also rotate synchronously, achieving synchronicity. The folding mechanism also includes an inclined telescopic member, the two ends of which are hinged to two rods on the same vertical side of the first part, or the two ends of which can also be hinged to two rods on the same vertical side of the second part. When the telescopic member is in its extended state, it can drive the first and second parts to rotate synchronously, changing the folding mechanism from an unfolded state to a folded state. When the telescopic member is in its shortened state, it can drive the first and second parts to rotate synchronously, changing the folding mechanism from a folded state to an unfolded state. Since the telescopic member only applies force to the first or second part, the first or second part can synchronously drive the other part to rotate along with it, achieving the folding or telescopic function of the folding mechanism. Compared to two electric push rods generating telescopic forces in different directions, this reduces the risk of malfunctions in the folding mechanism. Attached Figure Description

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0025] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] In the first aspect, the embodiments of this application provide a folding mechanism for an aircraft. This folding mechanism can connect the duct to the fuselage 3 of the aircraft, and after folding, it can reduce the overall volume of the aircraft, making it easier to transport. At the same time, it also makes it easier for the aircraft to pass through some narrow spaces, which is convenient for fire fighting.

[0027] like Figures 1 to 3 As shown, the folding mechanism includes a folding bracket, one end of which is connected to the duct, and the other end is connected to the fuselage 3 of the aircraft. The folding bracket includes a first part 1 and a second part 2 that can rotate synchronously with each other. Thus, when the first part 1 or the second part 2 is driven to rotate, the other part can also be driven to rotate synchronously, achieving synchronism. The folding mechanism also includes an inclined telescopic member 4, the two ends of which are respectively hinged to two rods on the same side of the vertical direction of the first part 1, or; the two ends of the telescopic member 4 can also be respectively hinged to two rods on the same side of the vertical direction of the second part 2; wherein, when the extension... When the retractable component 4 is in the extended state, it can drive the first part 1 and the second part 2 to rotate synchronously relative to each other, so that the folding mechanism changes from the unfolded state to the folded state. When the telescopic component 4 is in the shortened state, it can drive the first part 1 and the second part 2 to rotate synchronously relative to each other, so that the folding mechanism changes from the folded state to the unfolded state. Since the telescopic component 4 only applies force to the first part 1 or the second part 2, the first part 1 or the second part 2 can synchronously drive the other part to rotate together, so as to realize the folding or telescopic of the folding mechanism. Compared with two electric push rods generating telescopic forces in different directions, it can reduce the problem of folding mechanism failure.

[0028] Optionally, the first component 1 can be connected to the duct, and the second component 2 can be connected to the fuselage 3 of the aircraft. Of course, the first component 1 can also be connected to the fuselage 3 of the aircraft, and the second component 2 can be connected to the duct. For ease of description, in the embodiments of this application, the connection to the duct is limited to the first component 1, and the connection to the fuselage 3 of the aircraft is limited to the second component 2.

[0029] Optionally, the first split 1 can be equipped with two telescopic components 4, with the two telescopic components 4 tilting in the same direction and located on both sides of the first split 1; of course, the second split 2 can also be equipped with two telescopic components 4, with the two telescopic components 4 tilting in the same direction.

[0030] like Figure 2 and 3 As shown in Figures 4 and 5, optionally, the first segment 1 includes two first rods 11 and two second rods 12. The two first rods 11 are arranged in parallel and are located above the two second rods 12 in the extended state. The first rods 11 and second rods 12 on corresponding sides are also located on the same vertical plane. The first ends of the two first rods 11 and the two second rods 12 are hinged to the duct, and the second ends are rotatably connected to the second segment 2. One end of the telescopic member 4 can be hinged to the first end of the first rod 11 on the same side, and the other end can be hinged to the second end of the second rod 12 on the same side. The straight line formed by the hinge positions of the first rods 11 and the second rods 12 with the duct, the telescopic member 4, and the second rods 12 form a triangular structure. Since the first ends of the first rods 11 and the second rods 12 are hinged to the duct, when the telescopic member 4 gradually extends, with the duct as a reference, the second rod 12 is hinged to the duct. Positioned on the axis, it rotates downwards and swings. Simultaneously, the downward swinging force of the second rod 12 is transmitted to the first rod 11 through the support member 5. The first rod 11 and the second rod 12 swing in the same direction, and the first rod 11 and the second rod 12 gradually move closer together, realizing the folding of the first split 1. Since the second split 2 is connected to the first split 1, when the first rod 11 and the second rod 12 swing, they will also drive the third rod 21 and the fourth rod 22 in the second split 2, which are connected to the first rod 11 and the second rod 12 respectively, to swing synchronously. The second split 2 then folds towards the first split 1, thus realizing the folded state of the folding structure. At the same time, the first split 1 and the second split 2 are mechanically connected to achieve synchronous rotation. Compared with the electric push rod controlling the first split 1 and the second split 2 separately, it can reduce the failure problem of the folding mechanism and also ensure the synchronous movement of the first split 1 and the second split 2.

[0031] When the folding mechanism needs to be unfolded, the telescopic component 4 can be gradually shortened, and the movement process of each link is the opposite of the folding process described above.

[0032] like Figure 2 As shown, optionally, the second component 2 includes two third rods 21 and two fourth rods 22. The two third rods 21 are arranged in parallel and are located above the two fourth rods 22 when the folding mechanism is unfolded. The third rods 21 and fourth rods 22 on the corresponding sides are also located on the same vertical plane. The first ends of the two third rods 21 and the two fourth rods 22 are hinged to the body 3, and the second ends are respectively connected to the first rod 11 and the second rod 12. When the first rod 11 and the second rod 12 swing relative to the body 3, the third rods 21 and the fourth rods 22 also swing synchronously, thereby realizing the folding and unfolding of the folding mechanism.

[0033] As the telescopic component 4 gradually shortens, the folding mechanism changes from a folded state to an unfolded state.

[0034] The above implementation process is described with respect to when the telescopic member 4 is hinged to the first member 11 and the second member 12 respectively. If the telescopic member 4 is hinged to the third member 21 and the fourth member 22, the process is the same.

[0035] like Figure 2 and 3 As shown, optionally, the first segment 1 also includes a plurality of first connecting shafts 13, wherein the two ends of one first connecting shaft 13 are respectively rotatably connected to one end of two first rods 11, and the other first connecting shafts 13 are respectively rotatably connected to one end of two second rods 12, thereby improving the structural stability and structural strength of the first segment 1; the second segment 2 also includes a plurality of second connecting shafts 25, wherein the two ends of two second connecting shafts 25 are respectively hinged to one end of two third rods 21, and the other two are respectively rotatably connected to one end of two fourth rods 22, thereby improving the structural stability and structural strength of the second segment 2.

[0036] Optionally, the telescopic member 4 may also be hinged to the first end of the third member 21 on the same side and to the second end of the fourth member 22 in some cases.

[0037] like Figure 1 As shown, optionally, the body 3 is provided with two first lugs 31 and two second lugs 32. The two first lugs 31 are hinged to the first ends of the two third rods 21 through the second connecting shaft 25; the two second lugs 32 are also hinged to the first ends of the two fourth rods 22 through the second connecting shaft 25.

[0038] Optionally, the telescopic component 4 can be an electric telescopic rod, consisting of components such as a motor, reduction gear, lead screw, nut, and guide rail, which achieves linear motion by driving the lead screw to rotate through the motor. Of course, in some cases, the telescopic component 4 can also be a hydraulic cylinder, a pneumatic cylinder, an electromagnetic telescopic mechanism, or a multi-section electric lifting column, etc. Anything that can achieve the telescopic function is acceptable, and this application embodiment does not limit it.

[0039] like Figure 2 and 4 As shown, in one embodiment, the first part 1 includes a first rod 11 and a second rod 12 spaced apart, and the second part 2 includes a third rod 21 and a fourth rod 22 spaced apart. The first rod 11 is driven to the third rod 21, and the second rod 12 is driven to the fourth rod 22. Thus, when the telescopic member 4 is hinged to the first rod 11 and the second rod 12, the telescopic movement of the telescopic member 4 can drive the first rod 11 and the second rod 12 to swing relative to the body 3, and synchronously transmit to the third rod 21 and the fourth rod 22, so that the third rod 21 and the fourth rod 22 also swing, and the swing direction is opposite to that of the first rod 11 and the second rod 12, thereby realizing the folding and unfolding of the folding mechanism.

[0040] Optionally, when the telescopic member 4 is hinged to the third member 21 and the fourth member 22, the folding and unfolding principle of the folding mechanism is the same as described above.

[0041] Optionally, two of each of the first member 11, the second member 12, the third member 21, and the fourth member 22 can be provided; of course, more can also be provided.

[0042] Optionally, the end of the first rod 11 that is connected to the third rod 21 and the end of the second rod 12 that is connected to the fourth rod 22 can be connected by a belt to achieve synchronous rotation of the first split body 1 and the second split body 2; of course, they can also be connected by a chain to achieve synchronous rotation.

[0043] like Figures 2 to 5 As shown, in one embodiment, one end of the first rod 11 has a first tooth 111, one end of the second rod 12 has a second tooth 121, one end of the third rod 21 has a third tooth 211, and one end of the fourth rod 22 has a fourth tooth 241. The first tooth 111 meshes with the third tooth 211, and the second tooth 121 meshes with the fourth tooth 241, thereby realizing the transmission connection between the first split body 1 and the second split body 2. When the first split body 1 or the second split body 2 is driven to fold or unfold, the force can also be transmitted to the split body connected to it through mechanical connection, thereby realizing the folding or unfolding of the folding mechanism as a whole. It is not necessary to connect multiple electric push rods to the first split body 1 and the second split body 2 respectively. In this embodiment, the telescopic force brought by the telescopic member 4 on the first split body 1 or the second split body 2 can be transmitted to the first split body 1 and the second split body 2. Moreover, the mechanical connection can realize the synergy between the first split body 1 and the second split body 2, reducing the risk of failure of the folding mechanism.

[0044] Optionally, the first member 11, the second member 12, the third member 21, and the fourth member 22 all have teeth at their second ends.

[0045] Optionally, during the folding process, the first member 11 and the third member 21 rotate relative to each other, and the second member 12 and the fourth member 22 rotate relative to each other.

[0046] like Figure 2 , 4 As shown in Figure 5, in one embodiment, the first tooth 111 is located in a portion of the first rod 11, the second tooth 121 is located in a portion of the second rod 12, the third tooth 211 is located in a portion of the third rod 21, and the fourth tooth 241 is located in a portion of the fourth rod 22. That is, the teeth on the first rod 11, the second rod 12, the third rod 21, and the fourth rod 22 are all half-tooth structures, avoiding the first rod 11, the second rod 12, the third rod 21, and the fourth rod 22 being full-tooth structures. This can increase the structural strength of the first rod 11, the second rod 12, the third rod 21, and the fourth rod 22, thereby also improving the stability of the folding mechanism.

[0047] Optionally, a full-tooth structure means that the entire perimeter of the end of the first rod 11 is toothed, while a half-tooth structure means that at least half a circumference of one end of the first rod 11 is toothed.

[0048] like Figures 2 to 5 As shown, in one embodiment, two meshing gears are provided between the second tooth 121 and the fourth tooth 241. These two gears mesh with the second tooth 121 and the fourth tooth 241 respectively. By providing two meshing gears between the second tooth 121 and the fourth tooth 241, on the one hand, power transmission between the first split body 1 and the second split body 2 can be achieved, realizing synchronization; on the other hand, as... Figure 5 As shown, in the folded state, the two gears can increase the distance between the second rod 12 and the fourth rod 22 after folding, allowing the second rod 12 to swing as much as possible and approach a vertical state. At the same time, the fourth rod 22 is brought closer to the third rod 21 and is also close to a vertical state, thereby further reducing the space after folding and improving the space utilization of the folding mechanism. Without the two gears, an angle would be formed between the fourth rod 22 and the second rod 12 after folding, resulting in a larger volume after folding.

[0049] Optionally, in some cases, if the telescopic member 4 is hinged to the third rod 21 and the fourth rod 22, two gears may also be provided between the first tooth 111 and the third tooth 211.

[0050] Optionally, the diameters of the two gears can be the same as the diameters of the first tooth 111 and the third tooth 211, so that the second rod 12 and the fourth rod 22 are in a vertical state after folding, thus reducing the volume of the folding mechanism.

[0051] like Figure 2 and 5As shown, in one embodiment, the folding mechanism also includes a support member 5. The support member 5 is rotatably connected to the first tooth 111, the second tooth 121, the third tooth 211, the fourth tooth 241, and two gears. By setting the support member 5, the first split 1 and the second split 2 are supported and connected, thereby improving the stability of the folding structure. At the same time, the support member 5 also supports the two gears, so that the extension force of the telescopic member 4 can be smoothly transmitted to the second split 2 through the first split 1, so that the entire folding mechanism can operate smoothly.

[0052] Optionally, the support member 5 has a sheet-like structure, and a support member 5 is provided on both sides of each gear.

[0053] Optionally, the gear can be rotatably connected to the support members 5 on both sides via a shaft, and a limit structure is provided at both ends.

[0054] Optionally, the gears can be made of nylon to reduce the weight of the aircraft; the number of gears is even.

[0055] like Figure 2 As shown, optionally, the support member 5 and the first rod 11 can be hinged through the first connecting shaft 13. The first connecting shaft 13 can pass through the end of the first rod 11 and is provided with a limiting structure to prevent the support member 5 from shaking. The support member 5 and the second rod 12 can also be hinged through the first connecting shaft 13. The support member 5 is hinged to the third rod 21 and the fourth rod 22 through the second connecting shaft 25.

[0056] like Figure 2 , 3 As shown in Figure 5, in one embodiment, the first component 1 includes two first rods 11 connected by a first connecting shaft 13; a locking element 6 is provided on one side of the third rod 21, the locking element 6 including a locking hook, which is used to connect with the first connecting shaft 13 in the folded state of the folding mechanism, thereby locking the distance between the folded first rod 11 and the third rod 21, restricting gear rotation, and also restricting the unfolding of the folding mechanism, thus giving the folding mechanism good resistance to external impact, preventing the folding mechanism from being accidentally unfolded by external force, and facilitating transportation; at the same time, the locking element 6 can also stop the telescopic component 4 from working, reducing energy consumption.

[0057] Optionally, the locking element 6 can be manually operated to achieve locking.

[0058] like Figure 2 As shown, two locking pieces 6 can be fixed at both ends of one of the second connecting shafts 25 to improve the stability after locking.

[0059] In one embodiment, the folding mechanism also includes a driving member (not shown in the figure), which is connected to the locking member 6 and is used to drive the locking member 6 to rotate. When the folding mechanism is in the folded state, the automatic locking of the folding mechanism is achieved by driving the locking member 6 to rotate through the driving member.

[0060] Optionally, the drive unit can be connected to the locking unit 6 via a transmission, and the rotation angle of the drive unit can be determined by an angle sensor.

[0061] Optionally, the driving component can be a motor, which can be fixed to one side of the third rod 21 or fixed to the second connecting shaft 25.

[0062] Of course, the locking member 6 can also be deflected by electromagnetic control. For example, the deflection angle of the locking member 6 can be determined by a magnet and a Hall sensor, so that the locking member 6 can successfully lock the first connecting shaft 13.

[0063] Of course, the locking element 6 can also be set on the first connecting shaft 13 to lock the second connecting shaft 25.

[0064] like Figure 2 , 4 As shown in Figure 5, in one embodiment, the folding mechanism further includes a connector 7. The connector 7 includes a protrusion 71 and a main body 72 connected to the protrusion 71. One end of the first rod 11 is hinged to the protrusion 71, and one end of the second rod 12 is hinged to the main body 72 at the opposite end of the protrusion 71. By providing the connector 7, and the connector 7 having the protrusion 71, the hinge position of the first rod 11 and the connector 7 is closer to the body 3 than the hinge position of the second rod 12 and the main body 72. That is, the hinge position of the first rod 11 and the connector 7 is closer to the body 3. Compared to the second rod 12, the hinge position between the second rod 12 and the main body 72 is not on the same vertical line, but is in a convex state. In this way, when the folding mechanism is folded, it can avoid interference between the first rod 11 and the second rod 12, so that the first rod 11 and the second rod 12 can be as parallel to each other as possible after folding, thereby reducing the volume of the folding mechanism after folding. It also makes the third rod 21 and the fourth rod 22 close to each other after folding, thereby reducing the volume of the folding mechanism after folding and reducing the gap between the first rod 11 and the second rod 12 after folding.

[0065] Optionally, the connector 7 is a sheet-like structure, and the protrusion 71 and the main body 72 are in an L-shaped structure.

[0066] Optionally, the connector 7 and the duct can be hinged together by a shaft, and a limit structure is provided at the hinge position.

[0067] Optionally, the connector 7 is a sheet-like structure; in some cases, the second rod 12 may be hinged to the protrusion 71.

[0068] like Figure 4 and 5 As shown, optionally, the duct includes a support 8 located on the periphery of the duct body, the support 8 supports the entire duct, the support 8 is connected to the connector 7 by a shaft, and the first end of the second rod 12 is also connected to the support 8 by a shaft.

[0069] like Figure 2 As shown, optionally, the protrusion 71, the first rod 11, and the telescopic member 4 are hinged through the first connecting shaft 13. An axial limiting component can also be provided between two adjacent parts on the shaft to avoid contact and friction between adjacent parts.

[0070] Optionally, in the embodiments of this application, a limiting structure is provided at the hinge position to improve the stability of the folding mechanism, and an axial limiting component is provided between adjacent parts on the shaft.

[0071] Optionally, the first rod 11 and the second rod 12 are provided with receiving openings at the positions where they connect to the connector 7, thereby reducing the friction between them and the connector 7; the third rod 21 and the fourth rod 22 are also provided with receiving openings at the positions where they connect to the first lug 31 and the second lug 32, respectively, also in order to reduce friction.

[0072] Secondly, this application also provides an aircraft, which includes a fuselage 3 and ducts disposed on both sides of the fuselage 3. The ducts are connected to the fuselage 3 by a folding mechanism provided in the first aspect, which facilitates transportation and reduces the size, making it easier to pass through narrow areas.
