Description

Technical Field

[0001] The present application relates to the technical field of unmanned aerial vehicles, and in particular to a retractable unmanned aerial vehicle wing. Background Art

[0002] A drone is an unmanned aircraft that is operated by a radio remote control device and a self-contained program control device. As a small flying device, the wings of a drone extend from both sides of the fuselage. Some drones cannot have retractable wings, so during transportation and storage, the wings on both sides will take up a large transportation space, which is inconvenient to transport. Moreover, since the wings take up a large storage space, it is not conducive to storage. Moreover, during transportation, due to the long wings and poor anti-collision ability, the wings are at risk of being broken, requiring more careful packaging, which is cumbersome.

[0003] In order to solve the above problems, some drones divide the single wing into two sections, and use a telescopic device to extend or retract one section of the wing to shorten the length of the single wing. Some telescopic devices use electric control to achieve the telescopic movement of the wing. Although the wing can be locked, the structure of the electrically controlled telescopic device is complex. Some telescopic devices use springs to achieve the telescopic movement of the wing, but the two sections of the wing cannot be locked with each other. Under the influence of the spring elastic force and the inertia of the wing, the extended section of the wing will rebound, and after the wing is extended, the extended wing will shake, thereby affecting the stability of the entire wing.

DETAILED DESCRIPTION

[0029] The embodiments will be described in detail below, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following embodiments do not represent all implementation methods consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the Summary of the Invention.

[0030] In order to make the drone wings retractable, some drones divide the single wing into two sections, and use a telescopic device to extend or retract one section of the wing to shorten the length of the single wing. Some telescopic devices use electric control to achieve the telescopic movement of the wing. Although the wing can be locked, the structure of the electrically controlled telescopic device is complex. Some telescopic devices use springs to achieve the telescopic movement of the wing, but the two sections of the wing cannot be locked with each other. Under the influence of the spring force and the inertia of the wing, the extended section of the wing will rebound, and after the wing is extended, the extended wing will shake, thereby affecting the stability of the entire wing.

[0031] In order to solve the problem that the drone wing cannot be locked when automatically retracted, the embodiment of the present application provides a retractable drone wing, see Figure 1-Figure 3 The wing includes: a first wing 1, a second wing 2, a connecting tube 3, a fixed beam 5, a locking assembly 7 and a sliding connection seat 8, wherein the first wing 1 is slidably arranged on the outside of the second wing 2, one end of the second wing 2 is fixed to the drone body, and the slidable first wing 1 is arranged at the other end of the second wing 2.

[0032] The first wing 1 and the second wing 2 are both long and flat hollow hard shell structures. The connecting pipe 3 is a cylindrical structure, and the connecting pipe 3 is arranged inside the first wing 1 along the length direction of the first wing 1. The fixed beam 5 is arranged inside the second wing 2 along the length direction of the second wing 2, and can be fixed on the inner side of the second wing 2 by welding. In some embodiments, the fixed beam 5 can be a profile with a rectangular cross section, and a circular hole penetrating along the length direction is arranged inside the fixed beam 5. One end of the connecting pipe 3 is connected to one end of the first wing 1, and the other end of the connecting pipe 3 is slidably connected to the fixed beam 5. For example, a pipe sleeve can be arranged at the end of the first wing 1, and one end of the connecting pipe 3 is plugged into the pipe sleeve so that one end of the connecting pipe 3 can be fixed to the end of the first wing 1. The other end of the connecting pipe 3 is plugged into the fixed beam 5 through the circular hole and can slide along the fixed beam 5.

[0033] A first spring 4 is disposed in the fixed beam 5, one end of the first spring 4 is connected to the connecting tube 3, and the other end of the first spring 4 is connected to the end of the second wing 2 away from the first wing 1. In some embodiments, a countersunk hole may be disposed at the end of the connecting tube 3, a fixed shaft may be disposed at the end of the second wing 2 away from the first wing 1, one end of the first spring 4 is disposed in the countersunk hole, and the other end is sleeved on the outside of the fixed shaft, so that the first spring 4 can be limited in position in the fixed beam 5. When the first spring 4 is in a compressed state, the first wing 1 is retracted, and when the first spring 4 is in a free state, the first wing 1 is extended under the drive of the connecting tube 3.

[0034] A guide groove 51 is provided on one side of the fixed beam 5, and the guide groove 51 is provided along the length direction of the fixed beam 5. The sliding connection seat 8 is slidably connected to the guide groove 51 and is connected to the connecting pipe 3. For example, the sliding connection seat 8 may be a rectangular plate structure, and may be fixed to the connecting pipe 3 by welding. The cross section of the guide groove 51 may be rectangular. When the sliding connection seat 8 slides along the guide groove 51, it may be limited by the guide groove 51. When the connecting pipe 3 is ejected outwards under the elastic force of the first spring 4, the probability of the connecting pipe 3 shaking in the fixed beam 5 may be reduced, and the stability of the first wing 1 may be improved.

[0035] The locking assembly 7 is disposed on the inner side of the second wing 2, and the two ends of the second wing 2 are respectively provided with locking assemblies 7. In some embodiments, the locking assembly 7 can be disposed on the side where the guide groove 51 is disposed on the fixed beam 5, see Figure 4 The locking assembly 7 includes a first connecting column 72, a rotating disk 74, a locking shaft 76, a swing arm 77 and a second spring 78. The first connecting column 72 can be fixed on the side of the second wing 2 by welding, and the rotating disk 74 is rotatably connected to the second wing 2 through the first connecting column 72, so that the rotating disk 74 can rotate with the first connecting column 72 as the axis. The top surface of the rotating disk 74 is provided with a second connecting column 79, and the swing arm 77 is rotatably connected to the second connecting column 79, so that when the swing arm 77 swings, the rotating disk 74 can be driven to rotate. One end of the second spring 78 is connected to the second wing 2, and the other end of the second spring 78 is connected to the rotating disk 74, so that when the second spring 78 contracts, the rotating disk 74 can be driven to rotate. The swing arm 77 is arranged at one end of the rotating disk 74, and the second spring 78 is arranged at the other end of the rotating disk 74. One end of the locking shaft 76 is hinged to the rotating disk 74, so that when the rotating disk 74 rotates, the locking shaft 76 can be driven to reciprocate.

[0036] When the first wing 1 is extended, the sliding connection seat 8 automatically slides toward one end of the second wing 2 under the drive of the connecting tube 3, and contacts with the swing arm 77 of the locking assembly 7 at one end, so that the swing arm 77 swings, and then drives the turntable 74 to rotate, so that the locking shaft 76 extends out, plugs with the fixed beam 5 and one end of the connecting tube 3, and then automatically locks the first wing 1, so that the first wing 1 will not rebound, and at the same time, the probability of the first wing 1 shaking can be reduced, thereby improving the stability of the wing. When the turntable 74 rotates, the second spring 78 is stretched. When the first wing 1 needs to be retracted, the first wing 1 is pushed to slide toward the other end of the second wing 2, and the force between the swing arm 77 and the sliding connection seat 8 gradually decreases, and the second spring 78 contracts, driving the turntable 74 to rotate in the opposite direction, thereby retracting the locking shaft 76 and releasing the lock on the first wing 1.

[0037] In some embodiments, the swing arm 77 may be an L-shaped structure, one side of the L-shaped swing arm 77 is rotatably connected to the second connection column 79, and the other side is in contact with the sliding connection seat 8. In order to make the locking shaft 76 reciprocate, it is possible to arrange that before the sliding connection seat 8 abuts against the swing arm 77, the end of the locking shaft 76 is plugged into the fixed beam 5, so that the fixed beam 5 can serve as a limiter for the reciprocating movement of the locking shaft 76, and after the sliding connection seat 8 abuts against the swing arm 77, the locking shaft 76 is plugged into the connecting pipe 3.

[0038] When the first wing 1 is retracted, the sliding connection seat 8 slides toward the other end of the second wing 2 driven by the connecting tube 3, and finally abuts against the swing arm 77 of the locking assembly 7 at the other end. The swing arm 77 swings under the action of the sliding connection seat 8, thereby driving the turntable 74 to rotate, so that the locking shaft 76 extends out and is plugged into the fixed beam 5 and the other end of the connecting tube 3, which can automatically limit the first wing 1 to prevent the first wing 1 from being unable to find the retracted position when retracting.

[0039] The drone wing provided in the embodiment of the present application is configured such that a first spring 4 is arranged in the second wing 2 so that the first wing 1 can be automatically extended and retracted along the second wing 2. A locking assembly 7 and a sliding connection seat 8 are arranged in the second wing 2. When the first wing 1 is extended, the sliding connection seat 8 automatically abuts against the swing arm 77 in the locking assembly 7, and the locking shaft 76 is extended through the turntable 74 to be plugged into the connecting tube 3, thereby automatically locking the first wing 1 to solve the problem that the drone wing cannot be locked when automatically extended and retracted.

[0040] It should also be noted that when the first wing is retracted, the first spring 4 mainly bears pressure, so the first spring 4 is a compression spring; when the sliding connection seat 8 abuts against the swing arm 77, the second spring 78 mainly bears tension, so the second spring 78 is a tension spring.

[0041] See also Figure 6 In some embodiments, the sliding connection seat 8 includes a connection plate, an abutment block 81 and a sleeve 82. The connection plate can be a rectangular plate, and the two ends of the connection plate are respectively connected to the outer side surfaces of the two sleeves 82. The abutment block 81 is arranged on the top surface of the connection plate and can be connected to the connection plate by welding or integrally formed with the connection plate. By providing the abutment block 81, the abutment surface with the swing arm 77 can be enlarged, making the abutment more reliable.

[0042] See again Figure 3 In some embodiments, the number of connecting pipes 3 and fixed beams 5 is two, the two fixed beams 5 are symmetrically arranged, the sliding connection seat 8 is arranged between the two fixed beams 5, and the two ends of the sliding connection seat 8 are respectively connected to the connecting pipe 3 through sleeves 82, so that the sliding connection seat 8 can be fixed on the outside of the connecting pipe 3.

[0043] See again Figure 4 See also Figure 5 In some embodiments, the locking assembly 7 further includes a base 71, a limiting column 73 and a hinge plate 75. The base 71 may be a rectangular box structure, which may be fixed on the inner side of the second wing 2 by welding or bonding. The first connecting column 72 and the limiting column 73 are arranged in the base 71, and may be connected to the base 71 by welding. The first connecting column 72 may be arranged at the center of the base 71, and the turntable 74 is rotatably connected to the base 71 through the first connecting column 72. The turntable 74 is circular, and claws 741 are symmetrically arranged at the edge of the turntable 74. The claws 741 are engaged with the limiting column 73, and the turntable 74 may be limited, so that after the swing arm 77 abuts against the sliding connection seat 8, the rotation angle of the turntable 74 may just enable the locking shaft 76 to be plugged into the connecting pipe 3 and the fixed beam 5.

[0044] One end of the hinge plate 75 is hinged to the rotating disk 74, and the other end of the hinge plate 75 is hinged to the locking shaft 76. There are two hinge plates 75 and two locking shafts 76. The two hinge plates 75 are hinged to the rotating disk 74 respectively, and the two hinge plates 75 are symmetrically arranged. A pin can be arranged on the rotating disk 74 to hinge the hinge plate 75 with the rotating disk 74, so that the hinge plate 75 can rotate relative to the rotating disk 74. The two hinge plates 75 can be arranged at two ends of the rotating disk 74 that are perpendicular to the connecting line of the two claws 741. The two locking shafts 76 are hinged to the two hinge plates 75 respectively, and a first groove can be arranged at one end of the locking shaft 76, and the end of the hinge plate 75 away from the rotating disk 74 is arranged in the first groove, and is also hinged by the pin. When the rotating disk 74 rotates, the locking shaft 76 can be driven by the hinge plate 75 to perform telescopic reciprocating motion.

[0045] In some embodiments, a third connecting column is provided on the turntable 74, and the third connecting column is provided at one end of the turntable 74 away from the second connecting column 79. One end of the second spring 78 is connected to the inner side surface of the base 71, and the other end of the second spring 78 is connected to the turntable 74 through the third connecting column. For example, one end of the second spring 78 can be welded to the inner side surface of the base 71, and the other end of the second spring 78 can be sleeved on the third connecting column, so that the second spring 78 can be fixed between the base 71 and the turntable 74.

[0046] A clearance hole is provided on one side of the base 71 near the sliding connection seat 8, and the swing arm 77 abuts against the sliding connection seat 8 through the clearance hole, which can reduce the probability of the swing arm 77 coming off the second connection column 79 due to excessive force during abutment, and can also guide the swing arm 77. In some embodiments, the clearance hole can be a long hole. A through hole is provided on the side of the base 71 near the fixed beam 5, and the locking shaft 76 is plugged into the connecting pipe 3 and the fixed beam 5 through the through hole. In some embodiments, the through hole can be a circular hole, which can be used as a limit for the reciprocating motion of the locking shaft 76. Insertion holes are respectively provided on the sides of the connecting pipe 3 and the fixed beam 5. After the swing arm 77 abuts against the sliding connection seat 8, the locking shaft 76 is plugged into the connecting pipe 3 and the fixed beam 5 through the insertion hole.

[0047] See again Figure 2 The drone wing also includes a spring pin 9, which is a structural component that can be obtained through existing technology and is not described in detail in this application. The spring pin 9 is arranged on the outer side of the first wing 1. When the first wing 1 is retracted, the spring pin 9 is plugged into the second wing 2 so that the first wing 1 can be completely locked. When the first wing 1 needs to be extended, the spring pin 9 is pressed to release the lock of the first wing 1, so that the first wing 1 pops out under the action of the first spring 4. At the same time, since the locking assembly 7 is also provided at one end of the second wing 2 close to the fuselage, when the first wing 1 is retracted, the first wing 1 is first automatically locked by the locking assembly 7, that is, it reaches the retracted position. At this time, pressing the spring pin 9 can plug into the second wing 2 without confirming the retracted position of the first wing 1.

[0048] In some embodiments, the length of the second wing 2 can be set to be greater than the length of the first wing 1 to provide sufficient telescopic length for the first wing 1. The starting point of the guide groove 51 is the end of the fixed beam 5 close to the fuselage of the drone, and the length of the guide groove 51 is less than the length of the fixed beam 5, so that when the first wing 1 is extended, the sliding connection seat 8 can be pre-limited by the fixed beam 5 and will not fall out of the fixed beam 5, and the impact force on the swing arm 77 can also be reduced. In some embodiments, a second groove can also be set at the end of the guide groove 51 to facilitate observation of the sliding connection seat 8 during assembly.

[0049] In some embodiments, in order to reduce the weight of the entire wing, the first wing 1, the second wing 2, and the fixed beam 5 may be made of aluminum alloy, and the connecting tube 3 may be made of carbon fiber. It should also be noted that, since the second wing 2 is provided with the fixed beam 5 and the first spring 4 in the present application, the weight of the second wing 2 is relatively heavy, and therefore the second wing 2 is used as a fixed wing.

[0050] It can be seen from the above technical solutions that the embodiment of the present application provides a retractable drone wing, including: a first wing 1, a second wing 2, a connecting pipe 3, a fixed beam 5, a locking assembly 7 and a sliding connection seat 8, wherein the first wing 1 is slidably arranged on the outside of the second wing 2. One end of the connecting pipe 3 is connected to the first wing 1, and the other end is slidably connected in the fixed beam 5. The fixed beam 5 is in the second wing 2, and one end of the first spring 4 in the fixed beam 5 is connected to the connecting pipe 3, and the other end is connected to the second wing 2. The sliding connection seat 8 is slidably connected to the guide groove 51 on one side of the fixed beam 5, and is connected to the connecting pipe 3. The locking assembly 7 is arranged on the inner side of the second wing 2, and the locking assembly 7 includes a first connecting column 72, a rotating disk 74, a locking shaft 76, a swing arm 77 and a second spring 78. When the first wing 1 is extended, the sliding connection seat 8 abuts against the swing arm 77 at one end, and when the first wing 1 is retracted, the sliding connection seat 8 abuts against the swing arm 77 at the other end, and when abutting, the locking shaft 76 is respectively plugged with the two ends of the connecting tube 3. By arranging the first spring 4 in the second wing 2, the first wing 1 can be automatically extended and retracted along the second wing 2, and by arranging the locking assembly 7 and the sliding connection seat 8 in the second wing 2, when the first wing 1 is extended, the sliding connection seat 8 automatically abuts against the swing arm 77 in the locking assembly 7, and the first wing 1 can be automatically locked, so as to solve the problem that the drone wing cannot be locked when it is automatically extended and retracted.
