Description

Technical Field

[0001] This utility model relates to the field of drone connection devices, and in particular to a modular quick connection device for drones. Background Technology

[0002] Modular design for unmanned aerial vehicles (UAVs) is a software engineering approach that breaks down a large, complex system into a series of small, independent, and reusable modules. Each module has a defined function and interacts with other modules through interfaces. This design approach makes the system easier to understand, maintain, and extend, and the connections between modules should not be overly complex.

[0003] After modularization, existing drones are complex to assemble, and cannot be easily disassembled and assembled, nor can they be quickly connected. Many existing drones typically use bolts to fix the modules together, and after connection, appropriate bolts are needed to fix them. The connection process is time-consuming and laborious. Furthermore, the modularization of some existing drones is not clear enough, and the modules are classified in various ways, which makes the connection process even more complicated, greatly increasing the difficulty of connection and seriously affecting the connection speed.

[0004] Therefore, those skilled in the art have provided a modular quick-connect device for unmanned aerial vehicles (UAVs) to solve the problems mentioned 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 quick-connect device for unmanned aerial vehicles (UAVs). This device uses snap-fit ​​connections between modules, eliminating the need for bolts and enabling rapid connection with excellent stability. The interconnected wires between modules ensure current transmission during rapid connection. The dimensions of the snap-fit ​​connection between the propeller module and the payload module remain unchanged. By modularly designing different specifications and types of equipment and enabling rapid and stable connection, the applicable scenarios for UAVs are expanded.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular quick-connect device for unmanned aerial vehicles (UAVs), comprising a UAV body, with multiple arm slots formed on the upper part of the UAV body, a truncated cone fixedly mounted on the upper end of the UAV body, a top cover threaded around the truncated cone, arm modules being snapped into the multiple arm slots, a support block being fixedly mounted on the outer end of each of the multiple arm modules, a first slot being formed on the upper end of each of the multiple support blocks, a propeller module being snapped into the interior of each of the multiple first slots, a locking block being fixedly mounted on the lower sides of each of the multiple propeller modules, a charging port being formed at the lower end of each of the multiple propeller modules, and an inner slot being formed at the center of the front and rear ends of each of the multiple first slots;

[0007] Each of the multiple support blocks has a movable plate that slides through it below the first slot. Each of the multiple movable plates has a charging block that slides through it at the center of its upper and lower ends. Each of the multiple support blocks has two lower sliders that are engaged in the grooves at the lower end. Each of the multiple lower sliders has an upper slider that slides through it at the upper end. The upper ends of the multiple upper sliders are fixed to the lower end of the movable plate. Each of the multiple upper sliders and lower sliders has a spring between them.

[0008] Each of the multiple arm modules has two power terminals fixedly installed at the lower end of the rear protrusion. The lower end of the drone body has multiple slots of type 2, and each slot of type 2 has a load module that can be snapped into the arm module as needed. Then, the top cover is threaded onto the circumference of the truncated cone to press and fix the snapped arm module, which can achieve quick connection without removing the bolts. Multiple propeller modules are snapped into slot 1. The locking blocks on both sides move down along slot 1 to press down the movable plate. Due to the connection between the charging port and the charging block, the propeller module can drive the movable plate to rotate together when it rotates. When it rotates to the inner slot, it can be released and the locking block will spring into the inner slot under the influence of the spring, forming a stable snap-fit. This can achieve quick connection and also allows for easy replacement of propeller modules of other specifications.

[0009] Furthermore, two electrical connection slots are provided at the rear of the upper end of each of the multiple arm slots, and the dimensions of the multiple electrical connection posts are in close fit with the dimensions of the electrical connection slots;

[0010] With the above technical solution, when the multiple arm modules are snapped into the arm slots, the multiple electrical terminals are located inside the electrical slots, thus achieving circuit connection.

[0011] Furthermore, each of the propeller modules has a motor modularly installed inside, and each of the motor output shafts is fixedly equipped with a dual-wing propeller. The multiple load modules can be modularly assembled with various measuring and photographic equipment.

[0012] Through the above technical solution and modular design, each module can work independently after being connected to the relevant lines, which facilitates assembly and replacement, greatly improves the ease of use, and makes it applicable to more scenarios.

[0013] Furthermore, a wire is provided at the lower end of the charging block, the wire passes through the inside of the arm module and is connected to the power connection post;

[0014] With the above technical solution, when the power connection post and the power connection slot are connected, the current is connected to the charging block through the wire. When the charging block is connected inside the charging port, it provides power to the propeller module.

[0015] Furthermore, the rear end dimensions of multiple arm modules are all fitted to the internal dimensions of the arm slot;

[0016] The above technical solution allows the arm module to be more stably snapped into the arm slot, facilitating assembly and replacement.

[0017] Furthermore, the dimensions of the multiple propeller modules are all fitted to the dimensions of the first slot, the dimensions of the multiple card blocks are all fitted to the internal dimensions of the inner card slot, the dimensions of the multiple charging blocks are all fitted to the internal dimensions of the charging port, and the multiple sliding blocks can rotate within the internal slot of the bearing block;

[0018] The above technical solution allows the propeller module to be more stably snapped into the No. 1 slot, and enables quick and easy assembly.

[0019] Furthermore, the multiple load modules are connected to slot 2 and the propeller module is connected to slot 1 in the same way;

[0020] The above technical solution makes the clamping process of the load module as quick and stable as the assembly process of the propeller module into slot number one.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model proposes a modular quick connection device for unmanned aerial vehicles (UAVs). This device, by opening multiple arm slots, eliminates the need to fix the arm modules with bolts. Simply thread the top cover onto the circumference of the truncated cone to achieve clamping and fixation. The connection process is quick and convenient, and the connection method is simple, stable, and easy to operate. After selecting a propeller module with a suitable propeller specification, simply press it down to insert the charging block into the charging port, and then rotate it to insert the block into the inner slot to connect the two modules. The internal circuitry is rationally planned, and the payload module also adopts the same snap-fit ​​method, which improves the connection speed between modules and ensures stability.

[0023] 2. The present invention proposes a modular quick connection device for unmanned aerial vehicles (UAVs). The propeller module and the payload module of the device are modularly designed, and the dimensions of the snap-fit ​​joints between the two and the corresponding slots are consistent. This allows for the same assembly method while using propeller modules with propellers of different specifications and payload bodies equipped with different information collection devices. Through quick connection, it can be applied to a variety of different environments, thus expanding the working range of the UAV. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-4 The present invention provides an embodiment of a modular quick connection device for unmanned aerial vehicles (UAVs), comprising a UAV body 1. In order to enable the free assembly of a suitable number of arm modules 5, multiple arm slots 2 are provided on the upper part of the UAV body 1. The internal dimensions of the arm slots 2 are consistent with the dimensions of the rear end of the arm modules 5. After the arm modules 5 are engaged in the arm slots 2, the top cover 11 is threaded onto the frustum 4 to achieve the pressing and fixing of the arm modules 5. The frustum 4 is fixedly provided on the upper end of the UAV body 1, and the top cover 11 is threaded around the frustum 4. Arm modules 5 are engaged in the multiple arm slots 2.

[0032] Drones have different requirements for propeller specifications in different application scenarios. In order to enable propellers to be quickly assembled and replaced according to needs, a support block 6 is fixedly set on the outer end of multiple arm modules 5. A slot 7 is opened on the upper end of multiple support blocks 6. Propeller modules 8 are snapped into multiple slots 7. A locking block 10 is fixedly set on both sides of multiple propeller modules 8 near the bottom. A charging port 12 is opened at the lower end of multiple propeller modules 8. An inner locking groove 13 is opened at the center of the front and rear ends of multiple slots 7. During assembly, the propeller module 8 is aligned with the slot 7 and slid down to squeeze the movable plate 14. At this time, the charging block 17 will be inside the charging port 12. Rotating the propeller module 8 will also drive the movable plate 14 to rotate, which will further drive the lower slider 19 to rotate in the inner groove. When the whole rotation is so that the locking block 10 is in the inner locking groove 13, the propeller module 8 is released and the locking block 10 is sent into the inner locking groove 13 by the spring 16. This process is convenient and the locking is stable.

[0033] Multiple support blocks 6 have movable plates 14 that slide through them below the first groove 7. When the movable plates 14 are not compressed, their upper ends are in contact with the lower end of the first groove 7. Charging blocks 17 are installed through them at the center of the upper and lower ends of the multiple movable plates 14. Two lower sliders 19 are engaged in the grooves at the lower part of the multiple support blocks 6. Upper sliders 15 are installed through them at the upper part of the multiple lower sliders 19. The lower sliders 19 can rotate along the groove as the movable plates 14 rotate. The upper ends of the multiple upper sliders 15 are fixed to the lower end of the movable plates 14. Springs 16 are installed between the multiple upper sliders 15 and the lower sliders 19.

[0034] Two power terminals 20 are fixedly installed at the lower end of the rear protrusions of multiple arm modules 5. Multiple slots 22 are opened at the lower end of the UAV body 1. Each slot 22 has a load module 21 snapped into it. The load module 21 can be modularly designed with various measuring devices or sensors such as photography equipment. Then, it is snapped into the slot 22 in the same snapping method as the propeller module 8 and slot 7 to achieve quick connection and assembly.

[0035] Multiple arm slots 2 can be used to snap on arm modules 5 as needed. Then, the top cover 11 is threaded onto the circumference of the truncated cone 4 to press and fix the snap-on arm modules 5. This allows for quick connection without the need to remove bolts. Multiple propeller modules 8 are snap-on and set inside the first slot 7. The snap-on blocks 10 on both sides move down along the first slot 7 to press down the movable plate 14. Due to the connection between the charging port 12 and the charging block 17, the propeller modules 8 can drive the movable plate 14 to rotate together when rotating. When they rotate to the inner slot 13, they can be released so that the snap-on blocks 10 can be springed into the inner slot 13 by the influence of the spring 16, forming a stable snap-on connection. This allows for quick connection and convenient replacement of propeller modules 8 of other specifications.

[0036] Two electrical connection slots 3 are provided at the rear of the upper end of multiple arm slots 2. The dimensions of multiple electrical connection posts 20 are close to the dimensions of the electrical connection slots 3. When multiple arm modules 5 are snapped into the arm slots 2, the multiple electrical connection posts 20 are inside the electrical connection slots 3, realizing circuit connection. Multiple propeller modules 8 have motors modularly installed inside. The output shafts of multiple motors are fixedly equipped with dual-wing propellers 9. Multiple load modules 21 can be modularly assembled with various measuring and photographic equipment. Through modular design, each module can work independently after connecting the relevant circuits, which is convenient for assembly and replacement, greatly improving the convenience of use and making it applicable to more scenarios. The lower end of the charging block 17 is provided with a wire 18. The wire 18 runs through the inside of the arm module 5 and is connected to the electrical connection post 20. When the electrical connection post 20 is connected to the electrical connection slot 3, the current is connected to the charging block 17 through the wire 18. When the charging block 17 is connected to the charging port 12, it provides power to the propeller modules 8.

[0037] The rear dimensions of multiple arm modules 5 are all fitted to the internal dimensions of the arm slot 2, allowing the arm modules 5 to be more stably snapped into the arm slot 2, facilitating assembly and replacement. The dimensions of multiple propeller modules 8 are all fitted to the dimensions of slot 7. The dimensions of multiple locking blocks 10 are all fitted to the internal dimensions of the inner slot 13. The dimensions of multiple charging blocks 17 are all fitted to the internal dimensions of the charging port 12. Multiple sliding blocks 19 can rotate within the internal slot of the bearing block 6, allowing the propeller modules 8 to be more stably snapped into slot 7, and enabling quick and easy assembly. The snapping method of multiple load modules 21 with slot 22 and propeller modules 8 with slot 7 is the same, making the snapping process of load modules 21 as quick and stable as the process of assembling propeller modules 8 into slot 7.

[0038] Working principle: Depending on the application scenario, the device can unscrew the top cover 11 to quickly insert a suitable number of arm modules 5 into the arm slot 2 while ensuring overall stability. Then, the top cover 11 is threaded onto the circumference of the frustum 4 to press and fix the arm modules 5. Next, as needed, a propeller module 8 with a suitable dual-wing propeller 9 is selected, aligned with the first slot 7, and pushed downwards to the pressing movable plate 14. Pressing the movable plate 14 simultaneously presses the upper slider 15 and the spring 16, causing the lower slider 19 to slide inwards. When rotation is possible, it is rotated until the locking block 10 is in the inner locking position. When the propeller module 8 is released at slot 13, the spring 16 rebounds and moves the locking block 10 into the inner slot 13. During the rotation, the lower slider 19 will rotate along the inner slot. The whole process is quick and the locking effect is stable. The power connection post 20 is connected to the power connection slot 3. The wire 18 is connected to the power connection post 20 and the charging block 17. The charging block 17 is connected to the charging port 12 and then connected to the circuit. The load module 21 is locked into the second slot 22 in the same locking method as the propeller module 8 and the first slot 7. The load module 21 is modularized with the sensors and photographic equipment according to the required locking settings.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
