Description

Technical Field

[0001] This utility model relates to the field of fixed-wing unmanned aerial vehicle (UAV) technology, and in particular to a vertical take-off and landing (VTOL) fixed-wing UAV. Background Technology

[0002] A vertical take-off and landing (VTOL) fixed-wing drone is a type of drone that combines fixed-wing and vertical take-off and landing technologies. This type of drone can take off and land vertically like a helicopter, and can also fly at high speed and over long distances like a traditional fixed-wing aircraft. By using the VTOL method, it eliminates the runway limitation required by traditional aircraft, making it suitable for use in environments with limited space.

[0003] Traditional vertical takeoff and landing (VTOL) fixed-wing drones typically employ a rotor system during the vertical takeoff and landing phase. The rotor's rotation generates upward lift, overcoming the drone's gravity to achieve vertical ascent and hovering. During level flight, they switch to fixed-wing flight mode, utilizing the aerodynamic lift generated by the fixed wings on the frame to maintain flight. The power system provides forward thrust, enabling the drone to cruise at high speeds. However, in actual use, it has been found that when the drone lands, relying solely on the bottom rollers for support and stability weakens the stability, leading to the drone tilting and potentially causing damage, thus affecting its normal operation. Utility Model Content

[0004] The technical problem this invention aims to solve is that when a drone is landing, the bottom rollers alone provide support and stability, which weakens stability and causes the drone to tilt or fall, leading to damage and affecting its normal use.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a vertical take-off fixed-wing unmanned aerial vehicle (UAV), including a UAV body, a roller provided at the bottom of the UAV body, two fixed-wing propellers installed on the surface of the UAV body, a fixed-wing body installed on the surface of the UAV body, wherein rotors are respectively installed on both sides of the fixed-wing body, and a support device is provided on the surface of the fixed-wing body, wherein the support device assists the UAV body in stable landing.

[0006] The aforementioned components achieve the following effects: When the drone is in use, it generates upward lift by operating the rotor to achieve vertical ascent and hovering. After reaching a certain altitude, it switches to fixed-wing flight mode, using the aerodynamic lift generated by the fixed-wing propeller on the fixed-wing body to maintain flight. The power system provides forward thrust, enabling the drone to cruise at high speed. When the drone lands, the support device is activated to provide stable and protective landing measures for the drone.

[0007] Preferably, the support device includes two mounting shafts, which are respectively fixedly mounted on both sides of the surface of the fixed wing body. A support plate is rotatably mounted on the arc surface of the mounting shaft. A connecting plate is fixedly connected to one side of the surface of the support plate. Mounting frames are respectively mounted on both sides of the surface of the fixed wing body. Two coils are rotatably mounted on the inner wall of the mounting frames. A sprocket is mounted on one end of each coil, and the two sprockets are connected by a chain. A gear is mounted on one end of one coil, and the two gears mesh with each other. A servo motor is mounted on the surface of the fixed wing body. The output end of the servo motor is connected to one end of one coil through a coupling. Steel wire ropes are respectively mounted on the inner walls of the two coils, and the other ends of the two steel wire ropes are respectively connected and fixed to the connecting plate and the support plate.

[0008] The aforementioned components achieve the following effects: the vertical take-off and landing fixed-wing UAV will be more stable during landing, less prone to tilting or tipping over, thus preventing collision damage, ensuring normal use of the equipment, and improving the safety and convenience of use.

[0009] Preferably, the support device further includes a reinforcing rod installed at one end of the support plate, wherein the reinforcing rod improves the support effect of the support plate.

[0010] The effect achieved by the above components is that, by setting up the reinforcing rod, the contact point can be further increased when the support plate comes into contact with and is squeezed against the ground, thereby providing better support and protection for the drone body.

[0011] Preferably, the support device further includes clamping plates installed on both sides of the fixed wing body, wherein the clamping plates ensure the stable idle position of the support plates.

[0012] The effect achieved by the above components is that, through the setting of the clamping plate, when the support plate is rotated to a position that fits against the surface of the fixed wing body, it can be clamped in the inner wall of the clamping plate, thereby keeping it stable and not easily shaking, which would affect the flight of the UAV body.

[0013] Preferably, the support device further includes a stabilizing ring mounted on the surface of the fixed wing body, wherein the stabilizing ring covers the arcuate surfaces of the two gears.

[0014] The effect achieved by the above components is that, through the setting of the stabilizing ring, the two gears maintain a stable state when they mesh with each other.

[0015] Preferably, positioning plates are fixedly connected to both sides of the surface of the fixed wing body, wherein the positioning plates ensure the stability of the support plate in the deployed state.

[0016] The effect achieved by the above components is that, by setting the positioning plate, the support plate can contact and press against the positioning plate on the surface of the fixed wing body when it is in a supported state during rotation, thereby better maintaining the support effect under the pulling action of the steel wire.

[0017] Preferably, stabilizing grooves are provided on both sides of the surface of the support plate, wherein an arc-shaped plate is slidably disposed on the inner wall of the stabilizing groove, and the arc-shaped plate is connected and fixed to the surface of the fixed wing body.

[0018] The effect achieved by the above components is that, through the setting of the arc-shaped plate and the stabilizing groove, the support plate can be stably constrained by the arc-shaped plate when rotating, making it less prone to shaking, thereby ensuring the stable rotation of the support plate.

[0019] Preferably, positioning rods are fixedly connected to both sides of the surface of the fixed wing body, wherein two steel wire ropes are both inserted through the inner wall of the positioning rods.

[0020] The effect achieved by the above components is that, by setting the positioning rod, the two wire ropes can be guaranteed to have a certain stability when being wound up and down, and are not prone to loosening due to excessive stretching length, thereby ensuring the stability of the support plate.

[0021] The beneficial effects of this utility model are:

[0022] The vertical take-off fixed-wing UAV of this invention is more stable during landing, less prone to deviation and tipping, thus preventing collision damage, ensuring normal use of the equipment, and improving safety and convenience. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Figure 1 and Figure 2 The illustrated vertical take-off and landing fixed-wing UAV includes a UAV body 1, a roller 2 at the bottom of the UAV body 1, two fixed-wing propellers 4 mounted on the surface of the UAV body 1, a fixed-wing body 3 mounted on the surface of the UAV body 1, wherein rotors 5 are mounted on both sides of the fixed-wing body 3, and a support device 6 is provided on the surface of the fixed-wing body 3, wherein the support device 6 assists in the stable landing of the UAV body 1.

[0032] Figure 1 , Figure 2 and Figure 3As shown, when the drone body 1 is in use, the rotation of the rotor 5 is activated to generate upward lift, enabling vertical ascent and hovering. After reaching a certain altitude, it switches to fixed-wing flight mode, utilizing the aerodynamic lift generated by the fixed-wing propeller 4 on the fixed-wing body 3 to maintain flight. The power system provides forward thrust, enabling the drone body 1 to cruise at high speed. When the drone body 1 lands, the servo motor 610 on one side of the fixed-wing body 3 is activated. Because the two coils 65 of the mounting frame 64 are connected by a sprocket 67 and a chain 68, and the two fixed ropes on the coils 65 are wound in opposite directions, the two steel wire ropes 66 will be wound and unwound respectively. This pulls on the connecting plate 63 and the support plate 62 on its surface. At this time, the support plate 62 will rotate around the mounting shaft 61 on the fixed wing body 3. Because the coils 65 on both sides of the UAV body 1 are meshed through the gears 69, the support plates 62 on both sides will rotate synchronously until they are aligned with the rollers 2 below the UAV body 1. When the UAV body 1 lands, the support plates 62 on both sides will contact the ground at the same time. At this time, the vertical fixed wing UAV will be more stable when landing, less likely to deviate or tip over, resulting in collision damage, ensuring the normal use of the equipment, and improving the safety and convenience of use.

[0033] Figure 1 , Figure 2 and Figure 3 The support device 6 shown also includes a reinforcing rod 611 installed at one end of the support plate 62. The reinforcing rod 611 improves the support effect of the support plate 62. By setting the reinforcing rod 611, the contact point can be further increased when the support plate 62 is pressed against the ground, thereby better supporting and protecting the UAV body 1. The support device 6 also includes clamping plates 612 installed on both sides of the fixed wing body 3. The clamping plates 612 ensure the stable placement of the support plate 62. By setting the clamping plates 612, when the support plate 62 is rotated to a position that fits against the surface of the fixed wing body 3, it can be clamped in the inner wall of the clamping plates 612, thereby keeping it stable and not easily shaking, which would affect the flight of the UAV body 1.

[0034] Figure 1 , Figure 2 and Figure 4The support device 6 shown also includes a stabilizing ring 613 mounted on the surface of the fixed wing body 3. The stabilizing ring 613 covers the arc surface of the two gears 69. The stabilizing ring 613 ensures that the two gears 69 remain stable when they mesh with each other. Positioning plates 614 are fixedly connected to both sides of the surface of the fixed wing body 3. The positioning plates 614 ensure the stability of the support plate 62 in the unfolded state. The positioning plates 614 allow the support plate 62 to contact and press against the positioning plates 614 on the surface of the fixed wing body 3 when it is in a supporting state during rotation, thereby better maintaining the support effect under the pulling action of the steel wire.

[0035] Figure 1 , Figure 2 and Figure 4 The support plate 62 shown has stabilizing grooves 616 on both sides of its surface. An arc-shaped plate 615 is slidably installed on the inner wall of the stabilizing groove 616. The arc-shaped plate 615 is connected and fixed to the surface of the fixed wing body 3. The arc-shaped plate 615 and the stabilizing groove 616 ensure that the support plate 62 is stably limited by the arc-shaped plate 615 when rotating, making it less prone to shaking, thus ensuring the stable rotation of the support plate 62. Positioning rods 617 are fixedly connected to both sides of the surface of the fixed wing body 3. Two steel wire ropes 66 are inserted through the inner wall of the positioning rods 617. The positioning rods 617 ensure a certain degree of stability when the two steel wire ropes 66 are extended and retracted, preventing them from loosening due to excessive stretching, thus ensuring the stability of the support plate 62.

[0036] Working principle: When the drone body 1 is in use, the rotation of the rotor 5 is activated to generate upward lift, enabling vertical ascent and hovering. After reaching a certain altitude, it switches to fixed-wing flight mode, utilizing the aerodynamic lift generated by the fixed-wing propeller 4 on the fixed-wing body 3 to maintain flight. The power system provides forward thrust, enabling the drone body 1 to cruise at high speed. When the drone body 1 lands, the servo motor 610 (model SGM7A) on one side of the fixed-wing body 3 is activated. Because the two reels 65 of the mounting bracket 64 are connected by a sprocket 67 and a chain 68, and the two fixed ropes on the reels 65 are wound in opposite directions, the two steel wire ropes 66 will separate. The system prevents the connection plate 63 from being pulled and extended, thus pulling on the support plate 62 on the surface. At this time, the support plate 62 will rotate around the mounting shaft 61 on the fixed wing body 3. Because the coils 65 on both sides of the drone body 1 are meshed through the gears 69, the support plates 62 on both sides will rotate synchronously until they are aligned with the rollers 2 below the drone body 1. When the drone body 1 lands, the support plates 62 on both sides will contact the ground at the same time. At this time, the vertical fixed wing drone will be more stable when landing, less prone to tilting or falling, and thus less likely to cause collision damage, ensuring the normal use of the equipment and improving the safety and convenience of use.
