Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a general-purpose UAV. Background Technology

[0002] With the development of drone technology, its application scope is becoming increasingly wide. For example, photography, which is commonly used by the general public, can be done by equipping a camera on a rotary-wing drone and remotely controlling the drone to cruise and take pictures via a mobile phone. For example, for building inspection and maintenance, it is necessary to equip a rotary-wing drone with an extension arm, or even equip the front end of the extension arm with a suction cup structure, so that it can be extended and attached to the surface of the building to carry out inspection work. For example, it can lift objects and throw them to a designated location.

[0003] A typical drone on the market includes a fuselage, frame, landing gear, towing arms, and rotors. It is equipped with a control system and power supply and can be remotely controlled via remote control or mobile phone to take off, then cruise, perform operations, return to home, and land.

[0004] For example, the Chinese patent document "A Crack Detection UAV, Publication No. CN216509120U" uses a quadcopter UAV to describe a crack detection scheme for buildings. The UAV body is equipped with a probe arm and a crack detection mechanism. The crack detection mechanism includes a mechanical working arm and a crack detector, which can slide back and forth and extend outward along the probe arm, thereby realizing crack detection through the crack detector. It is equipped with landing gear for landing.

[0005] As mentioned above, drones are typically equipped with corresponding operational components based on the actual task. However, drones generally do not have a universal installation structure, making it difficult to replace and assemble various operational components. Utility Model Content

[0006] The purpose of this invention is to address the above-mentioned problems by providing a universal drone that can be equipped with application standard parts with different functional modules according to actual application scenarios, thereby enabling the replacement and assembly of various working components.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A general-purpose drone includes a drone body, which is equipped with a frame. The frame includes a body and a standard interface. The standard interface can be detachably connected to application standard parts that are compatible with the standard interface.

[0009] The standard interface is located in the middle of the frame and has a rectangular or regular polygonal structure. The standard interface can be a blind hole structure located at the top or bottom of the frame, in which case the working parts can only extend above or below the drone body to perform operations. Preferably, the standard interface is arranged vertically through the frame to facilitate assembly by plugging it into the interface. Furthermore, regardless of whether operations are performed above or below the drone body, these working parts can be assembled by plugging them into the standard interface using standard parts.

[0010] The outer wall of the standard component is rectangular or polygonal in shape to fit into the standard interface. The top of the standard component protrudes outward to form a brim-like structure, which can rest on the frame to bear weight and improve the stability of the detachable connection structure.

[0011] The drone body is equipped with an airframe, which is mounted on a frame. Specifically, standard components are plugged into the standard interfaces of the frame, and the airframe is bolted or welded to the outer wall of the frame (the back side of the standard interfaces).

[0012] To enable detachable connection and fixation, the frame also includes clamping components, which include clamping sub-components and clamping female-components. Several clamping female-components are installed on the outside of the standard interface of the frame, and several clamping sub-components can be installed on the application standard parts. The clamping sub-components and clamping female-components are used in pairs for detachable connection.

[0013] For example, the fastening component is a hook, the fastening female component is the buckle body, and the fastening female component is the hook body. The buckle body can be fastened to the hook body. The hook can be a stainless steel flat-mouth hook, a long hook, a spring hook, or an adjustable hook.

[0014] For example, the clamping component is a bolt lock, the clamping female component is the bolt component, and the clamping daughter component is the lock lug. The bolt component is arranged horizontally, and the bolt can extend or retract to connect with the lock lug. A conventional mechanical bolt lock is used, and locking and unlocking are achieved by the bolt extending and retracting to cooperate with the lock lug.

[0015] For example, the clamping component is an electronic lock, with the clamping mother component being the electronically controlled lock body and the clamping daughter component being the lock assembly. The electronically controlled lock body is electrically connected to the controller of the drone. The electronic lock is an electric bolt lock, with its electronically controlled lock body horizontally arranged, capable of extending or retracting to connect to the lock assembly. When energized, the electronically controlled lock body extends and inserts into the lock lug and other lock assemblies to achieve a tight clamping. Alternatively, the electronic lock is a magnetic lock, where the electronically controlled lock body can be energized to attract the lock assembly or de-energized to release it. When energized, the electronically controlled lock body generates a strong suction force to attract lock assemblies such as iron plates to achieve a tight clamping.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. The universal UAV of this utility model has a standard interface of rectangular or other shapes reserved in the center of the UAV body. The standard interface can be detachably connected to the outer wall of the application standard parts. The application standard parts can be designed with different functions. Therefore, application standard parts with different functional modules can be filled in according to the actual application scenario, and can be integrated with the main flight platform UAV to complete diverse tasks.

[0018] 2. This UAV can achieve the universalization of UAV flight platform, modularization of vehicle mission functions, multi-functional switching of one machine and arbitrary combination of wear and tear equipment to optimize the integrity rate, and modularization improves production efficiency and helps control costs.

[0024] Example 1

[0025] See Figures 1-13The general-purpose drone of this embodiment 1 includes a drone body 1, which is equipped with a frame. The frame includes a frame body 11, which is provided with a standard interface. The standard interface can be detachably connected to an application standard component 2 that is compatible with the standard interface.

[0026] The drone body includes a fuselage 3, frame, landing gear 12, support arm 13, and rotor 14. The fuselage 3 houses a lithium battery pack and a controller circuit board, which are connected and control the rotor's start and stop via standard cables. Both the drone body and its control system are existing technologies and will not be elaborated upon here; for example, DJI drones on the market; another example is the Chinese patent document "Landing Mechanism and Drone with Pressure Bar Type Landing," publication number CN219884123U, where the lower pressure bars of the landing gear form a landing fulcrum that vertically approaches and contacts the ground directly below it. The surface is fixed to support the drone body, enabling horizontal landing on uneven and irregular ground; for example, Chinese patent document "A Crack Detection Drone, Publication No. CN216509120U" illustrates a crack detection scheme for buildings using a quadcopter drone. The drone body is equipped with a probe arm and a crack detection mechanism, including a mechanical working arm and a crack detector, which can slide back and forth and extend outward along the probe arm to detect cracks. It is equipped with landing gear for landing; etc. This application improves the existing drone body frame and airframe installation structure. The frame has standard interfaces that can be set according to actual conditions, and the airframe can be externally assembled using welding or bolt connections.

[0027] To better balance the attitude of the drone, the standard interface is set in the middle of the frame 11. The standard interface has a rectangular or regular polygonal structure, as shown in the figure. This application uses the rectangular interface as an example for explanation.

[0028] The standard interface can be a blind hole structure located at the top or bottom of the frame, in which case the working parts can only extend above or below the UAV body to perform operations; preferably, the standard interface is arranged vertically through the interface to facilitate assembly by plugging in through the space above and below the interface, and regardless of whether the operation is above or below the UAV body, these working parts can be assembled by plugging in standard parts to the standard interface. As shown in the figure, this application uses a square tube frame surrounding the standard interface as an example for illustration.

[0029] The drone body is mounted on a frame. As shown in the figure, to accommodate the through-hole standard interface, standard components are inserted into the standard interface of the frame. The drone body is bolted or welded to the outer wall of the frame (the back side of the standard interface). Of course, if a blind-hole standard interface is used, the drone body can be installed in the non-through section.

[0030] Application standard component 2 includes a standard housing and functional components. The outer wall of the standard housing has a rectangular or regular polygonal structure in the middle that adapts to the standard interface for insertion into the standard interface. The top of the standard housing protrudes outward to form a brim-like structure, which can rest on the frame for load-bearing, improving the stability of the fixed connection of the detachable connection structure. The functional components can be installed inside the standard housing, in which case the housing is a box structure; they can protrude from the lower end of the standard housing, in which case the lower end of the housing has an extension opening; or they can protrude from the upper end of the housing, in which case the upper end of the housing has an extension opening; as shown in the figure, the explanation is based on the example of the functional components being arranged inside the housing and the housing having a box structure.

[0031] As mentioned above, assembly can be achieved using the brim structure and gravity, but it may come off in bumpy environments. Therefore, as a preferred embodiment of the above example, in order to achieve a detachable connection and secure fixation, the frame also includes a clamping component. The clamping component includes clamping sub-components and clamping female-components. Several clamping female-components are installed on the outside of the standard interface of the frame, and several clamping sub-components can be installed on the application standard parts. The clamping sub-components and clamping female-components are used in pairs for detachable connection.

[0032] Specifically, the fastening component is a hook and loop fastener, the fastening female component is the hook body 22, and the fastening female component is the hook body 21. The hook body 22 can be hooked and connected to the hook body 21. The hook and loop fastener is an existing technology, specifically a stainless steel flat-mouth hook and loop fastener, a long hook and loop fastener, a spring hook and loop fastener, or an adjustable hook and loop fastener, etc., which will not be described in detail here.

[0033] As mentioned above, when in use, the buckle is in the unfastened state. The standard part is inserted into the standard interface from top to bottom, and then the buckle body is fastened on the hook body to complete the assembly. After that, the drone can be controlled to take off and operate.

[0034] As mentioned above, a standard rectangular interface is reserved in the center of the UAV body. This interface allows for detachable connection to the outer wall of standard application components. These standard application components can be designed with different functional modules, allowing for integration with the main flight platform UAV to complete diverse tasks based on the specific application scenario. For example, a radar can be mounted on a standard application component to create a radar UAV; a telescope can be mounted on or below it to create a telescope UAV; a landing pad can be installed on the standard application component for takeoff or landing to create a mother-daughter UAV; an internal cavity can be created within the standard application component to house a communication station to create a communication relay UAV; and a sound wave detector can be mounted below the standard application component to create a sound wave detection UAV, and so on.

[0035] Example 2

[0036] The difference between this embodiment 2 and the aforementioned embodiment 1 lies in the structure of the clamping component. For other details not covered herein, please refer to embodiment 1.

[0037] In this embodiment 2 of the generalized UAV, the clamping component is a bolt lock, the clamping female component is a bolt component, and the clamping daughter component is a lock nose. For example, a lock nose is formed by opening a lock hole in a standard component. The bolt component is arranged horizontally by welding or bolting with a corner plate. The bolt can extend or retract to connect with the lock nose. This bolt lock is existing technology and will not be described in detail here. It adopts a conventional mechanical bolt lock, and locking and unlocking are achieved by the bolt extending and retracting to cooperate with the lock nose.

[0038] Example 3

[0039] The difference between this embodiment 3 and the aforementioned embodiments 1 or 2 lies in the structure of the clamping component. For other details not covered herein, please refer to embodiment 1.

[0040] In this embodiment 3, the universal UAV uses an electronic lock as the clamping component. The main clamping component is an electronically controlled lock body, and the secondary clamping component is a lock assembly. The electronically controlled lock body is electrically connected to the controller of the UAV body. The electronic lock is an electric bolt lock, with its electronically controlled lock body horizontally arranged and capable of extending or retracting to connect to the lock assembly. When energized, the electronically controlled lock body extends and inserts into the lock lug or other lock assemblies to achieve a tight clamping. Alternatively, the electronic lock can be a magnetic lock, where the electronically controlled lock body can be energized to attract the lock assembly or de-energized to release it. When energized, the electronically controlled lock body generates a strong suction force to attract lock assemblies such as iron plates to achieve a tight clamping. The electronic lock and its connection control with the UAV main controller are existing technologies and will not be elaborated upon here. Of course, referring to the principle of an electric bolt lock, a micro-motor can also be used to control the extension and retraction of the bolt through gear transmission to achieve locking. This will not be explained further here. The locking principle of electric bolt locks and bolt locks is the same, and using electric bolt locks allows for automated control.

[0041] Example 4

[0042] The difference between this embodiment 4 and the aforementioned embodiments 1, 2, and 3 lies in the structure of the clamping component. For other details not covered herein, please refer to embodiment 1.

[0043] In this embodiment 3, the universal UAV uses an elastic protrusion and a locking hole as fasteners, respectively located on the inner wall of the standard interface and the outer wall of the application standard part. The elastic protrusion bulges outward in its initial natural state and is compressed when the application standard part is inserted under a certain external force. It pops out when aligned with the locking hole, thus achieving assembly locking. When the application standard part is pulled out under a certain external force, it is compressed back down, thus achieving disassembly. The elastic protrusion is existing technology, such as the elastic locking mechanism when an umbrella unfolds, and will not be described further here.

[0044] It should be noted that the examples of the above embodiments can preferably be combined with one or more of each other according to actual needs, such as the combination of a sleeve and a slider structure, etc., and multiple embodiments use a set of combined technical features in the accompanying drawings, which will not be described in detail here. The take-off and landing mechanism of the UAV in the above embodiments is mainly applied to UAVs, but it is also applicable to other devices in the same / equivalent scenarios.

[0045] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
