Description

Technical Field

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

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices. From a technical perspective, they can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, and unmanned paragliders. Among them, unmanned multi-rotor aircraft are particularly widely used because of their stable performance and ease of operation.

[0003] However, the shell of existing unmanned multi-rotor aircraft is generally a one-piece molded structure. During the use of drones, when an accidental crash occurs, the frame on the shell used to connect the propeller is prone to breakage. The repair method is usually to replace the entire frame, which results in high repair difficulty and high repair costs.

[0004] Therefore, this application proposes a modular, combined multi-rotor unmanned aerial vehicle (UAV) to address the problems in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a modular, combined multi-rotor unmanned aerial vehicle (UAV).

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A modular, combined multi-rotor unmanned aerial vehicle (UAV) includes a main body and a fixing mechanism.

[0008] The main body of the drone is fixedly connected to multiple mounting bases, each mounting base having a rotor bracket inserted into it. The rotor brackets are fixedly mounted on the mounting bases via the fixing mechanism, and a rotor is fixedly mounted on one end of each rotor bracket.

[0009] The fixing mechanism includes a ring plate, a worm gear, a worm, a slider, a rotating plate, and a limiting block. A ring plate is rotatably fitted onto one end of each of the multiple rotor brackets. A worm gear is fixedly connected to the outer side of the ring plate. A worm is rotatably connected to each of the multiple mounting seats. The worm and the worm gear are meshed together. Through the cooperative design between the mounting seats, rotor brackets, and fixing mechanism, the rotor brackets are simply inserted into the mounting seat brackets. The worm gear and the worm wheel engage, allowing for rapid assembly of the rotor brackets and mounting seats. This facilitates maintenance and replacement of the rotor brackets, improving convenience and practicality.

[0010] Specifically, one end of the worm gear is threadedly connected to a slider, which is slidably connected to the corresponding mounting base. Through the threaded transmission between the worm gear and the slider, one side of the slider abuts against the mounting base. At this time, through the interaction between the worm gear and the slider, the worm gear is limited.

[0011] Specifically, a rotating plate is fixedly connected to one end of the worm gear, making it easy for the user to rotate the worm gear.

[0012] Specifically, each of the rotor brackets is fixedly connected to a limiting block, which is inserted into the corresponding mounting base. The limiting block is adapted to the worm gear, and the interaction between the limiting block and the slot can further limit the rotor bracket.

[0013] Specifically, each mounting base has a slot, which is adapted to the rotor bracket and the worm gear, so that the rotor bracket can be inserted into the mounting base.

[0014] Specifically, the mounting base has a slot that connects to the slot and corresponds to the worm gear. Through the interaction between the worm gear and the slot, the rotor bracket is fixed in a limited position.

[0015] Specifically, the mounting base has a cavity, the worm rotates in the cavity, and the cavity corresponds to the worm wheel, which facilitates transmission between the worm and the worm wheel.

[0016] Specifically, a sliding groove is provided on one side of the mounting base, and the slider slides in the sliding groove to facilitate the sliding of the slider.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model discloses a modular multi-rotor UAV. Through the cooperative design between the mounting base, rotor bracket, and fixing mechanism, the rotor bracket can be quickly assembled by simply plugging it into the mounting base bracket. The worm gear and worm wheel engage with the mounting base through the cooperative transmission between them, thus facilitating the maintenance and replacement of the rotor bracket and improving convenience and practicality.

[0027] Reference Figures 1-5 A modular multi-rotor unmanned aerial vehicle (UAV) includes a main body 1 and a fixing mechanism 4.

[0028] Multiple mounting bases 2 are fixedly connected to the main body 1 of the drone. Each mounting base 2 has a rotor bracket 3 inserted into it. The multiple rotor brackets 3 are fixedly installed on the multiple mounting bases 2 through a fixing mechanism 4. A rotor 5 is fixedly installed at one end of each of the multiple rotor brackets 3. The main body 1 of the drone is common in daily life and belongs to the prior art. It can be implemented by those skilled in the art. This application will not elaborate further.

[0029] The fixing mechanism 4 includes a ring plate 41, a worm gear 42, a worm 43, a slider 44, a rotating plate 45, and a limiting block 46. One end of each of the multiple rotor brackets 3 is rotatably fitted with a ring plate 41. The outer side of the ring plate 41 is fixedly connected to the worm gear 42. Each of the multiple mounting seats 2 is rotatably connected to a worm 43. The worm 43 and the worm gear 42 are meshed together. Through the cooperative design between the mounting seat 2, the rotor bracket 3, and the fixing mechanism 4, the rotor bracket 3 only needs to be inserted into the mounting seat 2. Through the cooperative transmission between the worm 43 and the worm gear 42, the worm gear 42 is engaged with the mounting seat 2, thereby achieving the effect of quick assembly between the rotor bracket 3 and the mounting seat 2. This facilitates the maintenance and replacement of the rotor bracket 3, improving convenience and practicality.

[0030] In this embodiment, one end of the worm 43 is threadedly connected to a slider 44, which is slidably connected to the corresponding mounting base 2. Through the threaded transmission between the worm 43 and the slider 44, one side of the slider 44 abuts against the mounting base 2. At this time, through the interaction between the worm 43 and the slider 44, the worm 43 is limited.

[0031] In this embodiment, a rotating plate 45 is fixedly connected to one end of the worm gear 43, which makes it convenient for the user to rotate the worm gear 43.

[0032] In this embodiment, limit blocks 46 are fixedly connected to multiple rotor brackets 3. The limit blocks 46 are inserted into the corresponding mounting bases 2. The limit blocks 46 are adapted to the worm gear 42. The interaction between the limit blocks 46 and the slots can further limit the rotor brackets 3.

[0033] In this embodiment, each mounting base 2 is provided with a slot, which is adapted to the rotor bracket 3 and the worm gear 42, so as to facilitate the insertion of the rotor bracket 3 and the mounting base 2.

[0034] In this embodiment, a slot is provided in the mounting base 2. The slot is connected to the slot and corresponds to the worm gear 42. Through the interaction between the worm gear 42 and the slot, the rotor bracket 3 is fixed and limited.

[0035] In this embodiment, a cavity is provided in the mounting base 2, and the worm 43 rotates in the cavity. The cavity corresponds to the worm wheel 42, which facilitates the transmission between the worm 43 and the worm wheel 42.

[0036] In this embodiment, a sliding groove is provided on one side of the mounting base 2, and the slider 44 slides in the sliding groove to facilitate the sliding of the slider 44.

[0037] Working principle: In use, firstly, insert one end of the rotor bracket 3, the worm wheel 42, and the limiting block 46 into the slots on the mounting base 2, so that the worm wheel 42 meshes with the worm 43 and the worm wheel 42 corresponds to the slot in the mounting base 2. Then, by rotating the rotating plate 45, the worm 43 rotates on the mounting base 2 and meshes with the worm wheel 42 for transmission. At the same time, one end of the worm 43 is threaded with the slider 44, causing the slider 44 to move into the sliding groove one on the mounting base 2.

[0038] During this process, the meshing transmission between the worm 43 and the worm wheel 42 causes the worm wheel 42 to drive the ring plate 41 to rotate at a certain angle on the rotor bracket 3, and causes the worm wheel 42 to move into the slot. At this time, through the interaction between the worm wheel 42 and the slot, the rotor bracket 3 is limited and fixed.

[0039] At the same time, the threaded transmission between the worm 43 and the slider 44 causes one side of the slider 44 to abut against the mounting base 2. At this time, the interaction between the worm 43 and the slider 44 achieves the effect of limiting the worm 43.

[0040] At the same time, the interaction between the limiting block 46 and the slot can further limit the rotor support 3.

[0041] Conversely, this allows for quick assembly and disassembly of the rotor support 3.

[0042] The technological advancement of this invention compared to the prior art is that the rotor bracket 3 can be quickly assembled and disassembled without the aid of tools through the cooperation of various components, thereby facilitating the maintenance of multi-rotor drones. Moreover, the structure is simple, greatly improving convenience and practicality.
