Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and particularly to a perching device for an unmanned aerial vehicle and an unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicles have become increasingly important due to their flexibility and efficiency in various application scenarios, including environmental monitoring, inspection and search and rescue, agricultural management, and urban surveillance. Although significant progress has been made in unmanned aerial vehicle technology, in practical applications, especially in tasks that require unmanned aerial vehicles to stay in a specific area for a long time, there are some limitations in the design and functions of existing unmanned aerial vehicles.

[0003] A major problem is that existing unmanned aerial vehicles mainly rely on continuous flight to maintain their position in the air, which not only consumes a large amount of energy, limiting the endurance time of the unmanned aerial vehicle, but also in some applications, such as urban environmental monitoring or wildlife observation, the noise generated by continuous flight may interfere with the surrounding environment and affect the execution effect of the task. In addition, long-term flight may also cause fatigue of the unmanned aerial vehicle operator and increase the operation risk.

[0004] Another problem is that existing unmanned aerial vehicles lack effective multi-surface perching ability. Most unmanned aerial vehicles can only stay in the air and cannot stably perch on other surfaces except the ground. This limits the application of unmanned aerial vehicles in complex environments, such as monitoring tasks on vertical walls, poles, or inverted surfaces. Due to the lack of a stable perching point, unmanned aerial vehicles cannot conduct long-term observation or data collection without consuming additional energy. Summary of the Invention

[0005] The technical problem to be solved by the present invention is: to provide a perching device for an unmanned aerial vehicle and an unmanned aerial vehicle that can perch on multiple surfaces.

[0006] To solve the above technical problem, the technical solution adopted by the present invention is: a perching device for an unmanned aerial vehicle, including an attachment device installed on the top of the fuselage and a contact and rotation device installed on the side of the fuselage. The contact and rotation device is used to make preliminary contact with the surface to be perched on and provide a rotation fulcrum for the fuselage, and the attachment device is used to attach to the surface to be perched on.

[0007] To solve the above technical problem, the present invention also provides an unmanned aerial vehicle, including a fuselage and the above perching device for an unmanned aerial vehicle.

[0008] The beneficial effects of the present invention are as follows: The perching device for drones and the drone provided by the present invention achieve the ability of the drone to perch on various surfaces by installing an attachment device on the top of the fuselage and a contact rotation device on the side. This design significantly improves the operation flexibility and task adaptability of the drone in complex environments, especially in scenarios where the drone needs to stay on different surfaces for a long time; the design of the contact rotation device enables the drone to make initial contact with the surface to be perched on and provides a rotation fulcrum, which is crucial for the precise positioning and stable attachment of the drone on vertical or inclined surfaces. In this way, the drone can achieve a smooth transition from the flight state to the perching state, reducing the risk of damage that may be caused by direct landing; the setting of the attachment device enables the drone to firmly attach to the surface to be perched on after the contact rotation device provides a fulcrum, whether it is a smooth wall surface, an inverted surface or other irregular surfaces. This stable attachment ability enables the drone to perform long-term monitoring tasks without consuming additional energy, thus significantly improving the energy utilization efficiency and endurance time.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] In order to describe in detail the technical content, the achieved objectives and the effects of the present invention, the following is described in conjunction with the embodiments and with reference to the accompanying drawings.

[0016] Please refer to Figures 1 to 4 , a perching device for an unmanned aerial vehicle, comprising an attachment device 2 installed on the top of the fuselage 1 and a contact and rotation device 3 installed on the side of the fuselage 1. The contact and rotation device 3 is used for making initial contact with the surface to be perched on and providing a rotation fulcrum for the fuselage 1, and the attachment device 2 is used for attaching to the surface to be perched on.

[0017] As can be seen from the above description, the beneficial effects of the present invention are as follows: By installing the attachment device 2 on the top of the fuselage 1 and the contact and rotation device 3 on the side, the ability of the unmanned aerial vehicle to perch on various surfaces is realized. This design significantly improves the operation flexibility and task adaptability of the unmanned aerial vehicle in complex environments, especially in scenarios where the unmanned aerial vehicle needs to stay on different surfaces for a long time; the design of the contact and rotation device 3 enables the unmanned aerial vehicle to make initial contact with the surface to be perched on and provide a rotation fulcrum, which is crucial for the precise positioning and stable attachment of the unmanned aerial vehicle on vertical or inclined surfaces. In this way, the unmanned aerial vehicle can achieve a smooth transition from the flight state to the perching state, reducing the risk of damage that may be caused by direct landing; the setting of the attachment device 2 enables the unmanned aerial vehicle to firmly attach to the surface to be perched on after the contact and rotation device 3 provides a fulcrum, whether it is a smooth wall surface, an inverted surface or other irregular surfaces. This stable attachment ability enables the unmanned aerial vehicle to perform long-term monitoring tasks without consuming additional energy, thus significantly improving the energy utilization efficiency and endurance time.

[0018] Further, the contact and rotation device 3 includes an elastic support 31 and a contact plate 32. One end of the elastic support 31 is connected to the fuselage 1, and the contact plate 32 is rotatably installed at the other end of the elastic support 31 and is used for making initial contact and positioning with the surface to be perched on.

[0019] As can be seen from the above description, the introduction of the design of the elastic support 31 and the contact plate 32 enables the unmanned aerial vehicle to make initial contact and positioning with the surface to be perched on more flexibly. The elastic characteristics of the elastic support 31 help to absorb the impact during contact, improving the stability and accuracy of the contact.

[0020] Further, the elastic support 31 is detachably installed on the fuselage 1.

[0021] As can be seen from the above description, the detachable design of the elastic support 31 improves the convenience of maintenance and replacement of the unmanned aerial vehicle, reducing the maintenance cost. This modular design also facilitates the quick replacement or upgrade of the elastic support 31 according to the task requirements.

[0022] Further, it further includes a grasping hook 4. The grasping hook 4 is rotatably installed on the elastic support 31 and is used for grasping the object to be perched on.

[0023] As described above, the addition of the grasping hook 4 enables the drone to effectively grasp the object to be perched on, enhances the attachment ability of the drone on rod-shaped objects or thin plates, and expands the application scenarios of the drone.

[0024] Furthermore, the elastic support 31 is provided with an avoidance hole 311 for avoiding the grasping hook 4.

[0025] As described above, the design of the avoidance hole 311 on the elastic support 31 provides necessary space for the grasping hook 4, avoids interference between the hook and the support during rotation, and ensures the free rotation of the hook and the grasping efficiency.

[0026] Furthermore, the attachment device 2 includes a deformable substrate 21, an adhesive member 22, and a deformation driving member 23. The deformable substrate 21 is installed on the top of the body 1. The adhesive member 22 is installed on the side of the deformable substrate 21 facing away from the body 1 and is used for adhering to the surface to be perched on. The deformation driving member 23 is installed on the side of the deformable substrate 21 facing away from the adhesive member 22 and is used for driving the surface of the deformable substrate 21 to deform.

[0027] As described above, the design of the deformable substrate 21, the adhesive member 22, and the deformation driving member 23 in the attachment device 2 enables the drone to actively adjust the adhesion force and position to adapt to different surface characteristics, improving the reliability and adaptability of the attachment.

[0028] Furthermore, the deformation driving member 23 is an SMA spring, and the SMA spring connects the opposite ends of the deformable substrate 21.

[0029] As described above, using the SMA spring as the deformation driving member 23 and utilizing its shape memory characteristic, precise control of the deformable substrate 21 is achieved. The SMA spring has a fast response speed and can quickly adjust the adhesion state, improving the reaction speed and attachment efficiency of the drone.

[0030] Furthermore, a barb device is also included. The barb device is installed on the side of the body 1 opposite to the contact and rotation device 3 and is used for puncturing the object to be perched on.

[0031] As described above, the introduction of the barb device enables the drone to puncture into the object to be perched on, such as a soft or rough surface, enhancing the attachment ability of the drone on non-planar or irregular surfaces.

[0032] Further, the hook and thorn device includes a fixed bracket 5, a rotating seat 6, a rotation driving member, and a thorn needle 64. The fixed bracket 5 is installed on the body 1. The thorn needle 64 is installed on the rotating seat 6 and is used for puncturing into the object to be perched on. The rotating seat 6 is rotatably installed on the fixed bracket 5. The rotation driving member is installed on the fixed bracket 5 and is used for driving the rotating seat 6 to rotate.

[0033] As can be seen from the above description, the design of the hook and thorn device allows the thorn needle 64 to puncture into the object to be perched on and fix the drone. The design of the rotating seat 6 and the rotation driving member enables the thorn needle 64 to adjust the puncture angle as needed, improving the attachment flexibility of the drone on complex surfaces.

[0034] Further, the fixed bracket 5 is further provided with a limiting member 52, and the limiting member 52 is located on the rotation trajectory of the rotating seat 6.

[0035] As can be seen from the above description, the design of the limiting member 52 on the fixed bracket 5 ensures the stability and safety of the rotating seat 6 during rotation, prevents the rotating seat 6 from over-rotating or derailing, and guarantees the reliability and durability of the hook and thorn device.

[0036] Please refer to Figures 1 to 4 , Embodiment 1 of the present invention is: an unmanned aerial vehicle, including a body 1 and a perching device for the unmanned aerial vehicle. The perching device for the unmanned aerial vehicle includes an attachment device 2 installed on the top of the body 1 and a contact and rotation device 3 installed on the side of the body 1. The contact and rotation device 3 is used for making preliminary contact with the surface to be perched on and providing a rotation fulcrum for the body 1. The attachment device 2 is used for attaching to the surface to be perched on. By means of the contact and rotation device 3, the unmanned aerial vehicle can make preliminary contact with the surface to be perched on and provide a rotation fulcrum, and this characteristic is crucial for the precise positioning and stable attachment of the unmanned aerial vehicle on vertical or inclined surfaces. Specifically, a plurality of motor mounts 11 are provided on the body 1 of the unmanned aerial vehicle. Motors are installed on the motor mounts 11, and propellers 12 are installed on the motors. The propellers 12 are driven by the motors to rotate to provide lift. When the contact and rotation device 3 makes preliminary contact and positioning with the surface to be perched on, the lift provided by the propellers 12 causes the body 1 to rotate relative to the fulcrum provided by the contact and rotation device 3 until the attachment device 2 is accurately aligned with the surface to be perched on of the object to be perched on, and it is applicable to perching surfaces at various inclined angles.

[0037] Preferably, the contact and rotation device 3 includes an elastic bracket 31 and a contact plate 32. One end of the elastic bracket 31 is connected to the body 1, and the contact plate 32 is rotatably installed at the other end of the elastic bracket 31 and is used for making initial contact and positioning with the surface to be perched on. The elastic characteristic of the elastic bracket 31 helps to absorb the impact during contact, improving the stability and accuracy of contact. Specifically, the elastic bracket 31 is detachably installed on the motor base 11 of the body 1. It can be understood that the detachable design of the elastic bracket 31 improves the convenience of maintenance and replacement of the drone and reduces the maintenance cost. This modular design also facilitates the quick replacement or upgrade of the elastic bracket 31 according to mission requirements.

Specifically, the deformation driving member 23 is an SMA spring, and the SMA spring connects the opposite ends of the deformable substrate 21. Using the SMA spring as the deformation driving member 23 and utilizing its shape memory characteristic, precise control of the deformable substrate 21 is achieved. The SMA spring has a fast response speed and can quickly adjust the adhesion state, improving the reaction speed and attachment efficiency of the drone. More specifically, two oppositely arranged first fixing seats 211 and two oppositely arranged second fixing seats 212 are further provided on the deformable substrate 21. The first fixing seat 211 is connected to the body 1, and the second fixing seat 212 is connected to the deformation driving member 23.
