Description

Technical Field

[0001] The present invention relates specifically to the technical field of aircraft, and in particular to a flapping wing mechanism of a water-air amphibious variant aircraft. Background Art

[0002] A water-air amphibious transformable aircraft is a cross-domain unmanned equipment that can efficiently switch movement modes between air and water media. Its core technology lies in the design of propulsion and lift systems that adapt to different medium fluid environments (air / water). However, existing water-air amphibious transformable aircraft have the following disadvantages when adapting to use: after the aircraft emerges from the water, a water film (thickness 0.5-3mm) adheres to the wings. If it is not discharged in time, the weight of the lifting surface will increase by 15-30%, thereby increasing energy consumption. Although some existing aircraft use a vibration mechanism to discharge part of the water on the entire wing, the same-direction vibration is prone to excessive concentration of resonant stress, causing a certain degree of damage to the aircraft fuselage, thereby affecting normal navigation. Summary of the Invention

[0003] To this end, the present invention proposes a flapping mechanism of a water-air amphibious variant aircraft to solve the problems raised in the above background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a flapping mechanism of an amphibious transformable aircraft, comprising:

[0005] A rotating disk, which is mounted on the driving wing shaft of the aircraft;

[0006] A main cylinder is fixed at the center of the top surface of the rotating disk, and four auxiliary cylinders are arranged in a circular array on the side wall of the main cylinder;

[0007] Wing seats, which are used to mount the rotors, and have the same number as the auxiliary cylinders, and each of the wing seats can be movably mounted on its corresponding auxiliary cylinder;

[0008] And a flapping wing driving mechanism is installed in the space formed by the combination of the main cylinder and each auxiliary cylinder, and the flapping wing driving mechanism can drive each wing seat to perform high-frequency up and down flapping movements.

[0009] Furthermore, preferably, the circular array on the side wall of the turntable has ear seats with the same number as the wing seats, each of the ear seats is rotatably connected to one end of the limiting component by a turn pin, and the other end of each of the limiting components is fixedly connected to the tail stock of the corresponding wing seat.

[0010] Furthermore, preferably, the fixing limiting component is always arranged parallel to the movable area surface of the wing seat.

[0011] Furthermore, preferably, the flapping drive mechanism includes:

[0012] A brushless motor is installed in the main cylinder, and a driving bevel gear is fixed to the driving end of the brushless motor;

[0013] And the driven vibration mechanism, which has the same number as the auxiliary cylinder and is respectively installed in each auxiliary cylinder, the inner end of each driven vibration mechanism is fixed with a driven bevel gear that meshes with the driving bevel gear for transmission, and the outer end of each driven vibration mechanism is connected to the corresponding wing seat.

[0014] Furthermore, preferably, the driven vibration driving mechanism includes:

[0015] a rotating frame, which is mounted in a bearing fixed in the auxiliary cylinder, and the driven bevel gear is fixed to one end of the rotating frame;

[0016] A driving ring is fixed in the other end of the rotating frame, and two pressure balls are fixedly embedded in the inner wall of the driving ring in a vertically symmetrical manner;

[0017] A driving rod, the outer end of which is fixedly connected to the wing seat, the inner end of which extends into the driving ring, and a plurality of elastic telescopic members are rotatably connected between the upper and lower end surfaces of the driving rod and the driving ring;

[0018] and a slope boss which is fixed on the side wall of the inner end portion of the driving rod and can be slidably connected with any one of the pressing balls.

[0019] Furthermore, preferably, the slope bosses in every two adjacent driven vibration driving mechanisms are inverted, so that the vibration directions of every two adjacent wing seats are always opposite.

[0020] Furthermore, preferably, a ring seat is fixed in the port of the secondary cylinder, a convex ring is fixed on the inner wall of the ring seat, and a ball groove rollingly connected to the ball ring is provided on the inner wall of the convex ring, and the ball ring is fixed on the driving rod.

[0021] Furthermore, preferably, the fixed component includes:

[0022] A lower sliding tube, the side wall of which is rotatably connected to a fixed end portion of a push cylinder;

[0023] An upper sliding tube is provided with a sliding cavity therein, a slider is slidably provided in the middle position of the sliding cavity, and a return spring is connected between the slider and the upper and lower end walls of the sliding cavity;

During this process, the ramp boss cyclically slides on the two pressure balls. Whenever the ramp boss contacts any pressure ball, the inclined surface of the ramp boss gradually abuts against the pressure ball, driving the drive rod to flip upward or downward. Then, when the ramp boss and the pressure ball slide into contact, the two no longer contact each other, causing the drive rod to return to its original position. This is repeated to achieve high-frequency vibration action to drain water from the wing.

[0028] Moreover, the vibration directions of each two adjacent wing seats are always opposite, and through the offsetting effect of partial forces, a certain dynamic balance effect is achieved, and the pressure loss of the wing components and fuselage caused by the same-direction vibration is avoided.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example: Please see the attached Figure 1-5 The present invention provides a technical solution: a flapping mechanism of a water-air amphibious transformable aircraft, comprising:

[0037] A rotating disc 4 is mounted on the driving wing shaft of the aircraft;

[0038] The main cylinder 2 is fixed at the center of the top surface of the rotating disk 4. Four auxiliary cylinders 1 are arranged in a circular array on the side wall of the main cylinder 2;

[0039] Wing seats 3, which are used to install the rotor, and the number of them is the same as the auxiliary cylinder 1, and each wing seat 3 can be movably installed on the corresponding auxiliary cylinder 1;

[0040] And a flapping drive mechanism, which is installed in the space formed by the main tube 2 and each auxiliary tube 1, and the flapping drive mechanism can drive each wing seat 3 to perform high-frequency up and down flapping movements.

[0041] In this embodiment, a circular array of lugs 7 is arranged on the side wall of the rotating disk 4, with the same number of lugs 7 as the wing seats 3. Each lug 7 is rotatably connected to one end of a retaining assembly 6 using a rotating pin, and the other end of each retaining assembly 6 is fixedly connected to the tailstock 5 of its corresponding wing seat 3.

[0042] In this embodiment, the fixing component 6 is always arranged parallel to the movable area of the wing seat 3;

[0043] That is, the limiting component 6 is used to limit the movement of the wing seat. That is, when the limiting component 6 is in a telescopic deformation state, it can appropriately rotate and make way by changing its length to cooperate with the wing seat to flap. Correspondingly, if the limiting component 6 is in a state where it cannot deform in length, it can stably support the wing seat in a fixed state.

[0044] In this embodiment, the flapping drive mechanism includes:

[0045] A brushless motor is installed in the main cylinder 2, and a driving bevel gear 8 is fixed to the driving end of the brushless motor;

[0046] And the driven vibration mechanism, which has the same number as the auxiliary cylinder 1 and is respectively installed in each auxiliary cylinder 1, the inner end of each driven vibration mechanism is fixed with a driven bevel gear 9 that meshes with the driving bevel gear 8, and the outer end of each driven vibration mechanism is connected to the corresponding wing seat 3.

[0047] In this embodiment, the driven vibration driving mechanism includes:

[0048] The rotating frame 10 is mounted in a bearing fixed in the auxiliary cylinder 1, and a driven bevel gear 9 is fixed to one end of the rotating frame 10;

[0049] A driving ring 14 is fixed to the other end of the rotating frame 10. Two pressure balls 15 are fixedly embedded on the inner wall of the driving ring 14 and are symmetrical in shape.

[0050] The driving rod 12 has an outer end fixedly connected to the wing seat 3, and an inner end of the driving rod 12 extends into the driving ring 14. A plurality of elastic telescopic members 16 are rotatably connected between the upper and lower end surfaces of the driving rod 12 and the driving ring 14;

[0051] and a ramp boss 17, which is fixed to the side wall of the inner end of the driving rod 12 and can be slidably engaged with any one of the pressure balls 15;

[0052] Specifically, when the brushless motor is started (at this time the limiting assembly 6 is in the unrestricted state), the rotating frame 10 is driven to rotate at high speed through the bevel gear set. During this process, the ramp boss 17 cyclically slides on the two pressure balls. Whenever the ramp boss 17 contacts any pressure ball, the inclined surface of the ramp boss 17 gradually contacts the pressure ball, driving the drive rod to flip upward or downward. Then, after the ramp boss 17 slides with the pressure ball, the two do not contact each other, causing the drive rod to return to its original position. This is repeated to achieve high-frequency vibration action to drain water from the wing.

[0053] In this embodiment, the inclined bosses 17 in each of the two adjacent driven vibration driving mechanisms are inverted, so that the vibration directions of each of the two adjacent wing seats 3 are always opposite;

[0054] That is to say, initially, the sloped boss 17 in one of the driven vibration driving mechanisms is set on the top surface of the driving rod, and the sloped boss 17 in the adjacent driven vibration driving mechanism is set on the bottom surface of the driving rod. This design method can make the vibration directions of each two adjacent wing seats 3 always opposite, and achieve a certain dynamic balance effect through the offset of partial forces, and avoid the situation where the same-direction vibration causes pressure loss to the wing components and the fuselage.

[0055] In this embodiment, a ring seat 11 is fixed in the port of the secondary cylinder 1 , a convex ring is fixed on the inner wall of the ring seat 11 , and a ball groove is provided on the inner wall of the convex ring for rolling connection with the ball ring 13 , and the ball ring 13 is fixed on the driving rod 12 .

[0056] In this embodiment, the fixed component 6 includes:

[0057] The lower descending tube 605 has a fixed end portion of a push cylinder 606 rotatably connected to its side wall;

[0058] The upper slide tube 601 has a slide cavity therein, a slider 603 slidably disposed in the middle of the slide cavity, and return springs 602 are connected between the slider 603 and the upper and lower end walls of the slide cavity;

[0059] One end of the sliding post 604 is fixedly connected to the lower slide tube 605, and the other end of the sliding post 604 penetrates into the sliding cavity of the upper slide tube 601 and is fixedly connected to the slider 603;

[0060] The U-shaped clamp 608 has two end legs that can be rotatably mounted on the lower slide tube 605. The head of the U-shaped clamp 608 can be rotatably connected to the driving block 607 fixed to the movable end of the push cylinder 606. When the push cylinder 606 is extended, the U-shaped clamp 608 can cooperate with the upper slide tube 601 to block it, so that the upper slide tube 601 and the lower slide tube 605 are relatively fixed.

[0061] Specifically, return springs are provided on both sides of the slider 603. When the slope boss presses the ball and creates a gap, the two return springs trigger high-frequency micro-oscillations through their respective elastic forces. Since the driving force will disappear briefly at the moment of disengagement, the high-frequency reciprocating oscillations of the return springs can provide continuous micro-driving force during the gap, reducing movement stagnation and making the next wing flapping more continuous.

[0062] In this embodiment, the contact areas of the U-shaped clip 608 and the upper sliding tube 601 are both provided with an anti-slip layer to enhance the frictional resistance therebetween and improve the relative fixing strength therebetween.

[0063] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
