Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) tool technology, and more specifically, to a multi-functional quick-release conversion device adapted to quadcopter UAVs. Background Technology

[0002] In today's era of rapid technological advancement, drone technology has made significant progress, and its applications are becoming increasingly widespread, deeply penetrating numerous industries such as film and television aerial photography, agricultural plant protection, logistics and distribution, power line inspection, and surveying and exploration. The functional requirements for drones vary significantly across industries. For example, film and television aerial photography requires drones equipped with high-definition and stable cameras to capture high-quality footage; agricultural plant protection demands drones with precise pesticide spraying capabilities and large payload capacity; logistics and distribution prioritize the drone's cargo capacity and flight range; power line inspection requires drones to flexibly navigate complex power facilities, carrying high-precision testing equipment for fault diagnosis; and surveying and exploration relies on drones equipped with specialized surveying instruments to achieve accurate measurements of complex terrain.

[0003] However, existing drones have many limitations in addressing these diverse needs. On one hand, most current drones are designed and manufactured with relatively fixed connections between their functional modules and the airframe. Once a functional module is installed on the drone's airframe, it is difficult to replace. This makes it impossible for the drone to quickly adjust its functional configuration when switching between different industry tasks, greatly limiting its application flexibility. For example, a drone originally used for aerial photography, if temporarily used for agricultural plant protection, is almost unable to complete the task because its functional modules cannot be easily replaced.

[0004] On the other hand, even if some drones are designed with interchangeable functional modules, the replacement process is usually quite cumbersome. It generally requires specialized tools such as screwdrivers and wrenches to remove multiple fixing screws before the module can be replaced. This not only consumes a significant amount of time and effort but also demands a certain level of expertise from the operators. In practical applications, such as urgent surveying missions, if frequent replacement of different functional modules is needed to adapt to the surveying requirements of complex terrain, this tool-dependent disassembly and installation method can severely impact work efficiency and may even delay the optimal execution time of the mission.

[0005] In conclusion, existing methods for installing and replacing drone functional modules can no longer meet the demands of today's rapidly evolving industry. Developing a quick-release functional adapter module that allows for rapid, tool-free assembly and disassembly is urgently needed. Utility Model Content

[0006] This specification provides a multi-functional quick-release conversion device adapted to quadcopter drones to overcome at least one technical problem existing in the related art.

[0007] According to the embodiments of this specification, a multi-functional quick-release conversion device adapted to a quadcopter drone is provided, comprising:

[0008] The drone body includes a quick-release mounting slot and a quick-release module; wherein the quick-release mounting slot is fixedly connected to the bottom of the drone body; the quick-release module has symmetrical guide bosses on both sides of its sidewall edges, the guide bosses extending along the installation direction of the quick-release module, and a limiting surface forming the middle area between the two guide bosses; the quick-release mounting slot has symmetrical guide grooves on both sides that cooperate with the guide bosses, a tensioning elastic arm in the middle, and locking elastic arms on both sides of the quick-release mounting slot, the locking elastic arms being used to engage with the limiting surface to lock the quick-release module.

[0009] In some alternative implementations, the quick-release mounting slot of the drone body is fixedly connected to the drone body by means of screws.

[0010] In some alternative embodiments, the front end of the guide boss has a chamfered guide structure so that the guide boss can mate with the guide groove.

[0011] In some alternative implementations, the limiting surface is a planar structure perpendicular to the installation direction of the quick-release module.

[0012] In some optional embodiments, the tensioning elastic arm is a first inclined structure with a preset extension length and a predetermined elastic deformation space; the first inclined structure includes a first cantilever structure with one end fixedly connected and the other end being a free end, the end of which is a planar structure that contacts the bottom surface of the quick-release module.

[0013] In some optional embodiments, the locking elastic arm is a second inclined structure with a preset extension length and a predetermined elastic deformation space; the structure of the second inclined structure includes a second cantilever structure with one end fixedly connected and the other end being a free end, the end of the second cantilever structure being used to engage the limiting surface.

[0014] In some alternative implementations, the quick-release mounting slot of the drone body is integrally injection molded from plastic material.

[0015] The beneficial effects of the embodiments in this specification are as follows:

[0016] 1. The guide bosses on both sides of the quick-release module and the guide grooves on both sides of the mounting slot cooperate with each other. This not only provides precise guidance for the installation of the quick-release module, but also allows the guide bosses to slide along the guide grooves during installation, ensuring that the quick-release module can accurately enter the installation position. It also restricts the vertical movement of the quick-release module. Through the close cooperation of the two, the degree of freedom of the quick-release module in this direction is constrained, further ensuring the stability and positional accuracy after installation, so that the quick-release module is accurately positioned to meet the usage requirements.

[0017] 2. The locking elastic arms on both sides of the mounting slot engage with the limiting surface of the quick-release module to form a solid locking structure. This structure can effectively resist the vibration, impact and airflow generated during the flight of the drone, prevent the quick-release module from loosening or falling off, and ensure the stability and reliability of the module during flight.

[0018] 3. The tensioning elastic arm in the middle of the mounting slot applies an upward tension force to the bottom surface of the quick-release module, which can make the module fit tightly with the mounting slot. This not only further enhances the stability of the connection, but also plays a role in buffering and shock absorption, reducing damage to the module and mounting slot caused by vibration, and extending the service life of the equipment.

[0030] The following is in conjunction with the appendix Figures 1-5 The structure and working principle of a multi-functional quick-release conversion device adapted to a quadcopter drone provided by this utility model are described.

[0031] like Figure 1 As shown, Figure 1 This is a schematic diagram of a multi-functional quick-release conversion device adapted to a quadcopter drone, provided in an embodiment of this specification. Figure 2 This is a schematic diagram of the quick-release mounting slot in the multi-functional quick-release conversion device for quadcopter drones provided in the embodiments of this specification. Figure 3 This is a schematic diagram of the quick-release module in the multi-functional quick-release conversion device adapted to a quadcopter drone provided in the embodiments of this specification. The quick-release conversion device may include a quick-release mounting slot 2 for the drone body and a quick-release module 3. The quick-release mounting slot 2 is fixedly connected to the bottom of the drone body 1. Guide bosses 301 are symmetrically arranged on the edges of the two side walls of the quick-release module 3, extending along the installation direction of the quick-release module 3, and a limiting surface 302 is formed in the middle area between the two guide bosses 301. Guide grooves 201 that cooperate with the guide bosses 301 are symmetrically arranged on both sides of the quick-release mounting slot 2, and a tensioning elastic arm 203 is provided in the middle. Locking elastic arms 202 are provided at the edges of both sides of the quick-release mounting slot 2, and the locking elastic arms 202 are used to engage with the limiting surface 302 to lock the quick-release module 3.

[0032] The above scheme will be explained in detail below. The quick-release conversion device mainly consists of a quick-release mounting slot 2 for the UAV body and a quick-release module 3. The mounting slot 2 is fixed to the bottom of the UAV body 1 and becomes the basic structure for the quick-release module 3 to connect to the UAV. This layout can ensure that the quick-release module 3 can be stably combined with the UAV body after installation without affecting the flight performance of the UAV.

[0033] The guide bosses 301 symmetrically arranged on the sidewall edges of the quick-release module 3 extend along the installation direction. This design provides precise guidance for the installation of the quick-release module 3. During installation, the guide bosses 301 cooperate with the guide grooves 201 on both sides of the quick-release mounting slot 2 on the UAV body, allowing the quick-release module 3 to slide accurately into the installation position. Moreover, the cooperation between the guide bosses on both sides of the quick-release module and the guide grooves on both sides of the mounting slot also restricts the vertical movement of the quick-release module. Through the close cooperation of the two, the degree of freedom of the quick-release module in this direction is constrained, further ensuring the stability and positional accuracy after installation, so that the quick-release module is accurately positioned to meet the usage requirements. At the same time, the intermediate area between the two guide bosses 301 forms a limiting surface 302. The limiting surface 302 provides a positioning benchmark for the installation depth and horizontal position of the quick-release module 3, which can ensure the consistency and accuracy of each installation. The quick-release mounting slot 2 of the UAV body not only features a guide slot 201 that mates with the guide boss 301, but also a tensioning elastic arm 203 in the middle and locking elastic arms 202 on both sides. The tensioning elastic arm 203 employs an elastic structure; after the quick-release module 3 is installed in place, it applies an upward force to the bottom surface of the quick-release module 3 through its own elastic deformation, ensuring a tight fit between the quick-release module 3 and the mounting slot 2, eliminating any potential gaps, enhancing connection stability, and buffering vibrations during UAV flight to reduce the shaking of the quick-release module 3. The locking elastic arm 202 engages with the limiting surface 302. When the quick-release module 3 is installed in the correct position, the locking elastic arm 202 uses its own elastic deformation to engage with the limiting surface 302, forming a robust mechanical locking structure to prevent the quick-release module 3 from accidentally falling off during flight, ensuring that the quick-release module 3 is reliably fixed to the UAV under various operating conditions.

[0034] Based on the technical solutions described above, this utility model also provides some more specific solutions, which will be described below.

[0035] In an optional embodiment, the quick-release mounting slot 2 of the drone body can be fixedly connected to the drone body 1 by means of screws.

[0036] This embodiment provides a method for fixing the quick-release mounting slot 2 of the drone body to the drone body 1. Specifically, by passing a screw through a pre-set screw hole or through hole on the quick-release mounting slot 2 of the drone body and then screwing it into the corresponding threaded hole on the drone body 1, the friction and mechanical engagement between the screw thread and the threaded hole are used to achieve a tight fixation between the quick-release mounting slot 2 of the drone body and the drone body 1. This connection method can provide reliable connection strength, ensuring that the quick-release mounting slot will not easily separate from the body during the drone's flight, thus ensuring the stability of the quick-release module and the overall drone.

[0037] In an optional embodiment, the front end of the guide boss 301 can be a guide structure with a chamfer, which cooperates with the guide slope of the guide groove 201 to form a progressive guide sliding structure.

[0038] In this embodiment, the guide boss 301 is designed with a chamfered guide structure. From an installation perspective, the chamfer makes it easier to align and insert the guide boss 301 when it approaches the guide groove 201, greatly reducing installation difficulty. During quick-release module installation, operators do not need to precisely align the guide boss 301 with the guide groove 201; as long as they are roughly close, the chamfer can provide guidance. For example, when the guide boss 301 approaches the guide groove 201, the inclined surface of the chamfer will first contact the entrance of the guide groove 201, guiding the guide boss 301 gradually into the guide groove 201. Without the chamfer, the right-angled edges of the guide boss might interfere with the edge of the guide groove, increasing the difficulty of docking.

[0039] In an optional embodiment, the limiting surface 302 is a planar structure perpendicular to the installation direction of the quick-release module 3.

[0040] In the technical solution of this embodiment, such as Figure 3 As shown, Figure 3 This is a schematic diagram of the quick-release module in the multi-functional quick-release conversion device adapted to a quadcopter UAV provided in the embodiments of this specification. The limiting surface 302 is a specific planar area on the quick-release module 3, presenting a flat and regular planar shape. In the structural layout of the quick-release module 3, it is located in the middle area between the two guide bosses 301. From the positional relationship, it is strictly perpendicular to the installation direction of the quick-release module 3. This vertical planar structural design makes the limiting surface 302 have a positioning function in the entire quick-release conversion device. Specifically, when the quick-release module 3 is inserted into the quick-release mounting slot 2 of the UAV body, the two guide bosses 301 slide along the guide groove 201, guiding the quick-release module 3 to accurately enter the installation position. When the quick-release module 3 reaches the correct position, the limiting surface 302 cooperates with the locking elastic arms 202 at the two edges of the mounting slot 2. Since the limiting surface 302 is a planar structure and perpendicular to the installation direction, it can achieve good contact and stable engagement with the locking protrusion at the end of the locking elastic arm 202. This engagement method ensures that the quick-release module 3 will not shift in the front-back or left-right directions after it is installed in place, thus achieving reliable locking of the quick-release module 3.

[0041] During drone flight, it is subjected to various external forces, such as vibration and impact. In this embodiment, the vertical limiting surface 302 can effectively resist these external forces, preventing the quick-release module 3 from shaking or loosening within the mounting slot 2. Simultaneously, the planar structure results in a relatively large contact area between the limiting surface 302 and the snap-fit ​​protrusion, thereby improving the stability of the connection and ensuring that the quick-release module 3 can be securely installed on the drone under various operating conditions, guaranteeing the normal operation and functionality of the drone.

[0042] In an optional embodiment, the tensioning elastic arm 203 can be a first inclined structure with a preset extension length, the first inclined structure having a predetermined elastic deformation space; the structure of the first inclined structure includes a first cantilever structure with one end fixedly connected and the other end being a free end, the end of the free end being a planar structure, the planar structure contacting the bottom surface of the quick-release module 3.

[0043] In this embodiment, the tensioning elastic arm 203 is designed as a first inclined structure with a preset extension length. It adopts a first cantilever structure with one end fixed and the other end free. Its preset extension length can ensure that there is enough space for elastic deformation during the installation of the quick-release module. Compared with other shapes, the inclined structure design can better exert the elastic effect in a limited space. When subjected to external force, the inclined surface can more effectively disperse stress and avoid local stress concentration that could lead to structural damage.

[0044] The first inclined structure of the tension elastic arm 203 has a predetermined elastic deformation space, enabling it to undergo elastic deformation under stress and return to its original shape after the force is removed. During the installation of the quick-release module 3 into the quick-release mounting slot of the UAV body, as the quick-release module 3 gradually approaches and is finally installed in place, the bottom surface of the quick-release module 3 contacts and compresses the free end of the tension elastic arm 203. At this time, the tension elastic arm 203, relying on its own elasticity, bends and deforms according to the predetermined elastic deformation space, generating an upward elastic force. During UAV flight, facing various vibrations and impacts, the elastic deformation of the tension elastic arm 203 can buffer these external forces, reducing damage caused by rigid collisions between the quick-release module 3 and the mounting slot, thereby extending the service life of the equipment.

[0045] Meanwhile, the free end of the tensioning elastic arm 203 has a planar structure, which contacts the bottom surface of the quick-release module 3. This planar contact increases the contact area with the bottom surface of the quick-release module, allowing the tension force to be evenly distributed on the bottom of the quick-release module. This avoids stress concentration due to insufficient contact area, which could damage the quick-release module or affect connection stability. Through this contact, the tensioning elastic arm 203 applies an upward tension force to the bottom surface of the quick-release module 3, ensuring a tight fit between the quick-release module 3 and the mounting groove. This effectively eliminates any small gaps that may exist between the quick-release module 3 and the mounting groove, preventing the quick-release module 3 from shaking or shifting during flight, and further enhancing connection stability.

[0046] In an optional embodiment, the locking elastic arm 202 can be a second inclined structure with a preset extension length, the second inclined structure having a predetermined elastic deformation space; the structure of the second inclined structure includes a second cantilever structure with one end fixedly connected and the other end being a free end, the end of the second cantilever structure being used to engage the limiting surface 302.

[0047] In this embodiment, the locking elastic arm 202 is designed as a second inclined structure with a preset extension length. It adopts a second cantilever structure with one end fixed and the other end free. The preset extension length provides sufficient space for its elastic deformation during the installation and disassembly of the quick-release module. During the installation of the quick-release module, the inclined surface of the inclined structure can guide the locking elastic arm 202 to smoothly contact the limiting surface 302, reducing installation resistance; during snap-fitting, the inclined surface can also form a tight fit with the limiting surface 302, enhancing the stability of the connection.

[0048] The second inclined structure has a predetermined elastic deformation space, which gives the locking elastic arm 202 good elastic performance. During the installation of the quick-release module 3, as the quick-release module gradually approaches the mounting slot, it will squeeze the locking elastic arm 202, causing it to undergo elastic deformation. Since the elastic deformation space is predetermined, the locking elastic arm 202 can bend smoothly within a tolerable range, making room for the insertion of the quick-release module. When the quick-release module is installed in place, the compressive force applied to the locking elastic arm 202 disappears, and it quickly returns to its original shape by relying on its own elastic restoring force, achieving engagement with the limiting surface 302. During the flight of the UAV, even if subjected to external forces such as vibration and impact, the locking elastic arm 202 can also buffer these external forces through its own elastic deformation, always maintaining a tight engagement with the limiting surface 302, preventing the quick-release module from loosening or falling off, and ensuring the stability and reliability of the quick-release module during flight.

[0049] The end of the second cantilever structure is used to engage with the limiting surface 302. When the quick-release module 3 reaches the correct installation position, the end of the locking elastic arm 202 precisely interacts with the limiting surface 302. This engagement method forms a mechanical locking structure, with the limiting surface 302 and the end of the locking elastic arm 202 tightly fitted, effectively limiting the displacement of the quick-release module in all directions. In practical applications, this engagement mechanism ensures that the quick-release module can be securely installed on the UAV even in complex flight environments. For example, under conditions of high-speed flight and unstable airflow, the quick-release module can still maintain a stable connection, ensuring the normal operation and functionality of the UAV.

[0050] In an optional embodiment, the quick-release mounting slot 2 of the drone body is integrally injection molded from plastic material.

[0051] In this embodiment, the quick-release mounting slot 2 for the drone fuselage is manufactured using a one-piece injection molding process with plastic material. This process involves heating and melting the plastic raw material, injecting it into a mold cavity using an injection molding machine, and then cooling and solidifying it to form the desired shape. This molding method allows for rapid, mass production of the quick-release mounting slot 2, completing the entire mounting slot manufacturing process in a single injection molding step, eliminating the need for complex assembly procedures. Since plastic has a lower density than metal, using plastic to manufacture the quick-release mounting slot 2 effectively reduces the overall weight of the drone, thereby improving its flight performance, such as extending flight time and enhancing maneuverability. Furthermore, due to the one-piece injection molding process, the quick-release mounting slot 2 is a complete, integral structure without seams or welding points. This results in higher structural strength, better able to withstand the external forces during the installation and removal of the quick-release module, as well as vibrations and impacts during drone flight. Compared to mounting slots assembled from multiple parts, the one-piece injection molding process reduces the probability of malfunctions caused by loose or damaged connections.

[0052] The following explains the installation and disassembly process of the quick-release module in the multi-functional quick-release conversion device adapted to quadcopter drones provided in the embodiments of this specification.

[0053] like Figure 4 As shown, Figure 4This diagram illustrates the installation process. First, align the guide bosses of the quick-release module with the quick-release mounting slots. The guide bosses are typically symmetrically distributed at the top edge of the quick-release module, while the quick-release mounting slots have matching guide grooves on both sides. When installation begins, the guide bosses sink into the guide grooves of the quick-release mounting slot, allowing the quick-release module to accurately enter the installation position along the predetermined path, preventing misalignment or jamming during installation. As the guide bosses sink into the guide grooves and the quick-release module continues to advance, it comes into contact with the locking elastic arms located at the edges of the mounting slot. Due to the elasticity of the locking elastic arms, they undergo elastic deformation and are flattened under the pressure of the quick-release module. At this point, the locking elastic arms bend inwards towards the mounting slot, creating space for further insertion of the quick-release module, allowing it to move smoothly horizontally within the mounting slot. With the guide bosses guiding along the guide grooves and the locking elastic arms providing space, the operator can then horizontally push the quick-release module into the mounting slot.

[0054] Once the quick-release module is pushed into place, the compressive force applied to the locking elastic arm disappears. Because the locking elastic arm itself has elastic recovery capability, it quickly returns to its original shape, popping out and engaging with the limiting surface of the quick-release module. The tight engagement between the locking elastic arm and the limiting surface forms a mechanical locking structure. This structure effectively prevents the quick-release module from retracting or loosening during drone flight due to external forces such as vibration and airflow impact, ensuring the quick-release module is securely installed in the mounting slot and achieving a reliable connection and locking function between the quick-release module and the drone body.

[0055] Figure 5 This diagram illustrates the assembly and disassembly process. During assembly and disassembly, first press the locking elastic arm by hand. When the quick-release module is installed in the quick-release mounting slot on the drone body and is in the locked state, the end of the locking elastic arm's locking protrusion engages tightly with the limiting surface of the quick-release module, firmly fixing the quick-release module in the mounting slot. When it is necessary to disassemble the quick-release module, the operator only needs to press the locking elastic arm directly by hand. This operation is simple and direct, requiring no additional tools. Because the locking elastic arm is made of elastic material, it undergoes elastic deformation when subjected to external force from a hand. Under pressure, the cantilevered part of the locking elastic arm bends towards the inside of the mounting slot, causing the end locking protrusion to gradually disengage from the limiting surface. This elastic deformation is reversible; once the external force disappears, the elastic arm will return to its original shape. However, during disassembly, continuous pressing maintains the deformation state of the elastic arm, thus unlocking the quick-release module.

[0056] Once the locking lug of the elastic arm is completely disengaged from the limiting surface, the quick-release module is no longer constrained by the locking force. At this point, the only interaction between the quick-release module and the mounting slot is the engagement of the guide boss and the guide groove, as well as the contact of the tensioning elastic arm. Due to the low sliding friction between the guide boss and the guide groove, the operator can easily pull the quick-release module out of the mounting slot along the direction of the guide groove, i.e., remove the adapter module from the mounting slot. During the extraction process, the tensioning elastic arm will elastically deform as the quick-release module moves, no longer applying tension to the bottom surface of the quick-release module, further facilitating the disassembly of the quick-release module.

[0057] Through the above series of actions, the quick-release function is ultimately achieved. This quick-release design can significantly improve the efficiency of replacing drone functional modules. In practical application scenarios, such as when switching between different tasks, operators can quickly remove the currently unnecessary quick-release modules from the drone and then install modules suitable for the new task, saving a lot of time and effort and improving the drone's flexibility and work efficiency.

[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
