Description

Technical Field

[0001] The present application relates to the field of drone take-off and landing technology, and in particular to a drone safety landing device for water field surveys. Background Art

[0002] Drones are widely used in various fields, including agricultural plant protection, geological exploration, forest fire prevention, and disaster relief. These applications often require a flat surface for takeoff and landing, which are typically controlled by a flight controller.

[0003] Drone technology also plays a vital role in aquatic biological monitoring, environmental surveys, and shoreline patrols. However, during aquatic field surveys, pilots typically arrive at designated waters by boat and conduct their work from aboard. This is often hampered by numerous unfavorable conditions, such as the small size of the vessel and the disturbance of wind and waves. The complex environment often makes it difficult to achieve ground-based takeoff and landing conditions for drones, forcing them to rely on handheld controls.

[0004] However, when a drone is taken off and landed by hand, it is very easy for the drone to lose control due to unstable center of gravity, and the high-speed rotating propeller wings may injure the flight controller. Therefore, there is an urgent need for a handheld structure that can be used for the safe takeoff and landing of drones to prevent injuries. Summary of the Invention

[0005] The purpose of this application is to provide a safe landing device for drones used for field surveys on water. When the traction structure is subjected to an external force, the clamping structures are driven closer to each other to clamp the drone, and when the external force on the traction structure is released, the reset structure drives the clamping structures away from each other to release the drone, so that the drone can be safely taken off and landed in the air without relying on the ground.

[0006] The present application provides a safety landing device for a drone used for field surveys on water, comprising:

[0007] A shell, enclosing to form a receiving cavity;

[0008] A clamping assembly, comprising a clamping structure and a connecting structure; the clamping structure is disposed outside the housing and is used to clamp or release the drone; the connecting structure is connected to the clamping structure, a portion of the connecting structure is disposed in the accommodating cavity, and the connecting structure is used to synchronously drive the clamping structure to move when the connecting structure moves; and

[0009] The adjustment component includes a traction structure and a reset structure arranged in the accommodating cavity; the traction structure is connected to the connecting structure; the traction structure is used to apply a force to the connecting structure when subjected to an external force, so as to drive the clamping structures to move closer to each other and thus clamp the drone; the reset structure is connected to the connecting structure; the reset structure is used to apply a force to the connecting structure when the external force acting on the traction structure is released, so as to drive the clamping structures to move away from each other and thus release the drone.

[0010] In an embodiment of the present application, the traction structure applies a force to the connecting structure when subjected to an external force, thereby driving the clamping structures to approach each other and thus clamp the drone; and the reset structure applies a force to the connecting structure when the external force acting on the traction structure is released, thereby driving the clamping structures to move away from each other and thus releasing the drone, so that the drone can take off and land safely in the air without relying on the ground.

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0017] In the description of this application, it should be understood that the terms "first", "second", "third" and "fourth" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0018] An embodiment of the present application provides a safety landing device 2 for a drone used for field surveys on water, including a housing 100 , a clamping assembly 300 , and an adjustment assembly 500 .

[0020] The clamping assembly 300 includes a clamping structure 301 and a connecting structure 302; the clamping structure 301 is arranged outside the shell 100 and is used to clamp or release the drone; the connecting structure 302 is connected to the clamping structure 301, and a part of the connecting structure 302 is arranged in the accommodating cavity 101. The connecting structure 302 is used to synchronously drive the clamping structure 301 to move when it moves.

[0021] The adjustment component 500 includes a traction structure 510 and a reset structure 530 arranged in the accommodating cavity 101; the traction structure 510 is connected to the connecting structure 302; the traction structure 510 is used to apply a force to the connecting structure 302 when subjected to an external force, so as to drive the clamping structures 301 to move closer to each other and thus clamp the drone; the reset structure 530 is connected to the connecting structure 302; the reset structure 530 is used to apply a force to the connecting structure 302 when the external force acting on the traction structure 510 is released, so as to drive the clamping structures 301 to move away from each other and thus release the drone.

[0022] It can be understood that in the embodiment of the present application, the traction structure 510 applies a force to the connecting structure 302 when it is subjected to an external force, so as to drive the clamping structures 301 to approach each other and thus clamp the drone, and the reset structure 530 applies a force to the connecting structure 302 when the external force applied to the traction structure 510 is released, so as to drive the clamping structures 301 to move away from each other and thus release the drone, so that the drone can take off and land safely in the air without relying on the ground.

[0023] It is understandable that the external force acting on the traction structure 510 may be a force manually applied by the flight controller. The external force acting on the traction structure 510 may also be a force applied by the flight controller through mechanical components.

[0024] In some embodiments, the drone safety landing device 2 further includes a support platform 200, which is disposed on the housing 100 and located between the clamping structure 301 and the housing 100. The support platform 200 is used to lift the drone so that the adjustment assembly 500 can clamp the drone. It is understood that the support platform 200 can be a flat plate structure.

[0025] In some embodiments, the support platform 200 is made of EVA, which makes the support platform 200 light, flexible, non-slip and waterproof, ensuring that the drone can be stably supported and preventing the drone from sliding when parked on the support platform 200.

[0028] Among them, the adjustment component 500 is used to apply a first force in a direction away from the clamping structure 301 or a second force in a direction toward the clamping structure 301 to the connecting rod body 355, so as to drive the connecting rod 350 to slide relative to the first connecting part 314 and the second connecting part 334, thereby driving the first connecting part 314 and the second connecting part 334 to rotate relative to the shell 100, and then driving the first head 312 and the second head 332 to move closer to or away from each other.

[0029] In some embodiments, the shapes of the first head 312 and the second head 332 are adapted to fit the drone body, and flexible material is provided on opposite sides of the first head 312 and the second head 332 to prevent damage to the drone body and prevent the drone from slipping when the first head 312 and the second head 332 clamp the drone body. The flexible material may be sponge.

[0030] In some embodiments, the first connection portion 314 and the second connection portion 334 may be made of polypropylene, so that the first connection portion 314 and the second connection portion 334 have greater hardness and toughness.

[0031] In some embodiments, the first connecting portion 314 located at the part of the first shaft 316 away from the first head 312 is the first connecting sub-portion 3142, and the second connecting portion 334 located at the part of the second shaft 336 away from the second head 332 is the second connecting sub-portion 3342. The first connecting sub-portion 3142 and the second connecting sub-portion 3342 are both arc-shaped structures bent toward each other.

[0032] In some embodiments, the other portion of the first connecting portion 314 connected to the first connecting sub-portion 3142 may be an arc-shaped structure integral with the first connecting sub-portion 3142, or may be other shaped structures, such as a serpentine structure, a bow structure, or a wavy structure.

[0033] In some embodiments, the first connecting portion 314 and the second connecting portion 334 are both curved structures that curve toward each other. The first connecting portion 314 is provided with the first head portion 312 at one end, and the second connecting portion 334 is provided with the second head portion 332 at one end. The middle portion of the first connecting portion 314 is referred to as the first middle portion; the middle portion of the second connecting portion 334 is referred to as the second middle portion. The first connecting portion 314 is divided into a first portion proximate to the first head portion 312 and a second portion distal to the first head portion 312 by the first middle portion. The first shaft 316 is provided in the second portion. The second connecting portion 334 is divided into a third portion proximate to the second head portion 332 and a fourth portion distal to the second head portion 332 by the second middle portion. The second shaft 336 is provided in the fourth portion.

[0034] In some embodiments, the middle part of the first shaft 316 is fixedly connected to the first connecting portion 314, and the two ends of the first shaft 316 are rotatably connected to the shell 100; the first shaft 316 is located on the side of the connecting rod 350 facing the first head 312; the second clamping component 330 also includes a second shaft 336; the middle part of the second shaft 336 is fixedly connected to the second connecting portion 334, and the two ends of the second shaft 336 are rotatably connected to the shell 100; the second shaft 336 is located on the side of the connecting rod 350 facing the second head 332.

[0036] In some embodiments, the first connecting sub-portion 3142 is provided with a first sliding groove 3144, which is arranged along the extension direction of the first connecting sub-portion 3142; the second connecting sub-portion 3342 is provided with a second sliding groove 3344, which is arranged along the extension direction of the second connecting sub-portion 3342; the first end 351 is disposed in the first sliding groove 3144 and is movably connected to the first sliding groove 3144; the second end 353 is disposed in the second sliding groove 3344 and is movably connected to the second sliding groove 3344;

[0037] It is understood that when the connecting rod body 355 is subjected to a first force, the first end 351 slides along the first sliding groove 3144 away from the first head 312, and the second end 353 slides along the second sliding groove 3344 away from the second head 332, causing the connecting rod 350 to move to the side of the first connecting sub-portion 3142 and the second connecting sub-portion 3342 away from the first shaft 316 and the second shaft 336. When the connecting rod body 355 is subjected to a second force, the first end 351 slides along the first sliding groove 3144 toward the first head 312, and the second end 353 slides along the second sliding groove 3344 toward the second head 332, causing the connecting rod 350 to move to the side of the first connecting sub-portion 3142 and the second connecting sub-portion 3342 toward the first shaft 316 and the second shaft 336.

[0038] In some embodiments, the first slide groove 3144 is arranged on the side of the first connecting sub-part 3142 facing the second connecting sub-part 3342, and the second slide groove 3344 is arranged on the side of the second connecting sub-part 3342 facing the first connecting sub-part 3142, and the first slide groove 3144 and the second slide groove 3344 are arranged opposite to each other.

[0039] In other embodiments, the first sliding groove 3144 is disposed on a first side of the first connecting sub-portion 3142, and the second sliding groove 3344 is disposed on a second side of the second connecting sub-portion 3342, and the first side and the second side are on the same side of the connecting structure 302. The first end 351 of the connecting rod 350 is disposed perpendicularly to the connecting rod body 355, and the second end 353 of the connecting rod 350 is disposed perpendicularly to the connecting rod body 355, and the first end 351 and the second end 353 of the connecting rod 350 are located on the same side of the connecting rod body 355.

[0040] In some embodiments, the traction structure 510 includes a pressing component 511 and a traction rope 513 ; one end of the traction rope 513 is fixed to the connecting rod body 355 , and the other end of the traction rope 513 is fixed to the pressing component 511 .

[0041] The reset structure 530 includes a support member 531 and a first elastic member 533. The first elastic member 533 encloses a hollow passage. The support member 531 is disposed in the accommodating cavity 101 and is used to support the first elastic member 533. The support member 531 has an opening for accommodating the traction rope 513. One end of the first elastic member 533 is connected to the support member 531, and the other end of the first elastic member 533 is connected to the connecting rod body 355. The traction rope 513 is arranged to pass through the hollow passage of the first elastic member 533 and the opening of the support member 531.

[0042] It is understood that when a force is applied to the pressing component 511 in a direction away from the clamping structure 301, the pressing component 511 can drive the traction rope 513 to move away from the clamping structure 301, thereby causing the traction rope 513 to pull the connecting rod 350 in a direction away from the clamping structure 301. The connecting rod 350 then compresses the first elastic member 533 and simultaneously drives the first head 312 and the second head 332 to move toward each other. When the force applied to the pressing component 511 in a direction toward the clamping structure 301 is released, the first elastic member 533 can release its elastic force and push the connecting rod 350 in a direction toward the clamping structure 301, thereby driving the first head 312 and the second head 332 to move away from each other. It is understood that the first elastic member 533 can be a compression spring.

[0043] In some embodiments, the housing 100 includes a first housing portion 110 and a second housing portion 130 connected to each other; the first housing cavity 101a formed by the first housing portion 110 is connected to the second housing cavity 101b formed by the second housing portion 130; the first housing cavity 101a and the second housing cavity 101b form a housing cavity 101; the first housing portion 110 is a hollow column; the clamping structure 301 and the connecting structure 302 are arranged at one end of the first housing portion 110 away from the second housing portion 130; the first connecting sub-portion 3142, the second connecting sub-portion 3342 and The connecting rod 350 is arranged in the first accommodating cavity 101a; the reset structure 530 is also arranged in the first accommodating cavity 101a; the second shell portion 130 is box-shaped with a first opening 130a and a second opening 130b arranged at intervals; the second shell portion 130 includes a bottom wall 132 and a side wall 134 arranged on the same side of the bottom wall 132; the side wall 134 encloses a first opening 130a and a second opening 130b; the first opening 130a is used to accommodate the extension of the handle 5112; the second opening 130b is connected to the first accommodating cavity 101a to accommodate the extension of the traction rope 513.

[0044] The direction of the bottom wall 132 from the end close to the second opening 130b toward the end away from the second opening 130b is a first direction H1; the direction of the first shell portion 110 from the end close to the second opening 130b toward the end away from the second opening 130b is a second direction H2; the angle between the first direction H1 and the second direction H2 is an obtuse angle.

[0045] The pressing component 511 includes a handle 5112 and a slide 5114; the bottom wall 132 is provided with a guide rail 136 along the first direction H1; the handle 5112 is movably arranged in the second accommodating cavity 101b; the handle 5112 and the second shell part 130 as a whole can be grasped by a human hand to manually apply a force to the handle 5112 toward the bottom wall 132; the slide 5114 includes a first end 5114a and a second end 5114b arranged in opposite directions; the first end 5114a is connected to the handle 5112, and the second end 5114b is slidably connected to the guide rail 136, and the guide rail 136 is arranged along the first direction H1; the traction rope 513 is fixed to the second end 5114b of the slide 5114.

[0046] It is understood that when a force is applied to the handle 5112 toward the bottom wall 132, the handle 5112 moves toward the bottom wall 132, causing the slide 5114 to be simultaneously subjected to the force and slide into the guide rail 136, thereby driving the traction rope 513 to move away from the clamping structure 301. When the force applied to the handle 5112 toward the bottom wall 132 is released, the handle 5112 moves away from the bottom wall 132, the force exerted by the traction rope 513 on the connecting rod 350 decreases, and the first elastic member 533 can release its elastic force and push the connecting rod 350 toward the clamping structure 301, thereby driving the traction rope 513 to pull the elastic piece to slide along the guide rail 136 in the opposite direction of the first direction H1, while driving the handle 5112 to move away from the bottom wall 132.

[0047] It is understood that the direction of the bottom wall 132 from the end proximal to the second opening 130b toward the end distal to the second opening 130b is a first direction H1; the direction of the first housing portion 110 from the end proximal to the second opening 130b toward the end distal to the second opening 130b is a second direction H2; and the angle between the first direction H1 and the second direction H2 is an obtuse angle. On the one hand, since the drone safety landing device 2 provided in the embodiment of the present application requires the first housing portion 110 to remain in a vertical position during use, the obtuse angle between the first direction H1 and the second direction H2 facilitates the human hand's grip on the handle 5112 and the entire second housing 100, thereby facilitating manual control of the handle 5112 to achieve movement of the handle 5112 toward the bottom wall 132 and apply force to the slide 5114. On the other hand, the first direction H1 and the second direction H2 form an obtuse angle, so that when a force is applied, the slide 5114 automatically slides along the guide rail 136 in the first direction H1, thereby driving the traction rope 513 to move, ultimately enabling the clamping structure 301 to clamp the drone. Therefore, the obtuse angle between the first direction H1 and the second direction H2 facilitates manual control of the clamping structure 301 to clamp the drone.

[0048] It is understood that the first end 5114a of the slide 5114 is connected to the handle 5112, and the second end 5114b of the slide 5114 is slidably connected to the guide rail 136. The slide 5114 is curved toward the handle 5112. The slide 5114 can be an elastic metal sheet. For example, the slide 5114 can be a flexible steel sheet. The slide 5114 can also be an elastic plastic sheet.

[0049] In some embodiments, the side of the handle 5112 facing away from the slide 5114 is configured in a wavy shape to facilitate gripping by the fingers of a human hand. The handle 5112 is made of polypropylene, which gives it strong hardness and toughness. In some embodiments, the second housing portion 130 is made of ABS engineering material, making the second housing portion 130 lightweight, hard, heat-resistant, cold-resistant, impact-resistant, and corrosion-resistant. In some embodiments, the first housing portion 110 and the second housing portion 130 can be fixed to each other via a connecting structure 302 such as screws. In some embodiments, the housing 100 can be an integrally molded structure.

[0050] In some embodiments, the handle 5112 further includes a buckle 5116 , which is disposed on a side of the handle 5112 opposite to the side wall 134 ; the side wall 134 is provided with a limiting opening 1341 .

[0051] It is understood that when the handle 5112 moves toward the bottom wall 132 to a first distance, the buckle 5116 can be engaged with the limiting opening 1341, so that the traction rope 513 applies a stable force to the connecting rod 350, thereby maintaining a stable clamping state between the first head 312 and the second head 332. When the buckle 5116 is disengaged from the limiting opening 1341, the first elastic member 533 can release the elastic force to push the connecting rod 350 to move, thereby changing the first head 312 and the second head 332 from the clamped state to the open state.

[0052] In some embodiments, the buckle 5116 includes a pad 5116d, a second elastic member 5116c, a main body 5116b and a protrusion 5116a that are connected in sequence; the pad 5116d is connected to the handle 5112; the limit opening 1341 is an opening; the size of the limit opening 1341 is between the size of the main body 5116b and the size of the protrusion 5116a.

[0053] It is understood that when the buckle 5116 moves to the limiting opening 1341, the elastic force of the second elastic member 5116c is released, the protrusion 5116a is able to extend out of the limiting opening 1341, and the main body 5116b abuts against the inner edge of the limiting opening 1341, thereby achieving the engaging connection between the buckle 5116 and the limiting opening 1341. When a force is applied to the protrusion 5116a toward the main body 5116b, the second elastic member 5116c is compressed by the pressure, and the protrusion 5116a is withdrawn from the limiting opening 1341, thereby achieving the disengagement of the buckle 5116 from the limiting opening 1341.

[0054] It can be understood that the second elastic member 5116c can be a compression spring.

[0055] In some embodiments, the drone safety landing device 2 also includes at least one limit member 700, and at least one limit member 700 is fixed to the inner wall of the first shell part 110 and arranged at intervals in the first accommodating cavity 101a; a through hole is provided in the middle of the limit member 700 for accommodating the passage of the traction rope 513.

[0056] It can be understood that when the traction rope 513 is arranged in a manner of passing through the through hole of the limiting member 700, the through hole of the limiting member 700 plays a limiting role on the traction rope 513, so that the traction rope 513 can maintain movement in the extension direction of the hollow channel of the first elastic member 533, thereby preventing the traction rope 513 from being caught by other components or getting tangled in itself, causing it to be unable to perform the traction function.

[0057] The above is a detailed introduction to the drone safety landing device provided in the embodiments of the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea; at the same time, for technical personnel in this field, based on the ideas of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
