Description

Technical Field

[0001] This invention relates to an optoelectronic integrated conversion module for unmanned aerial vehicles (UAVs). Background Technology

[0002] With the widespread application of drones in the market, their use of radio for control makes them susceptible to interference from electromagnetic fields and the environment. This also affects the real-time performance of signals transmitted back to the ground control station and the high-definition quality of images. This is especially true in short-distance applications such as aerial photography and videography, patrol / surveillance, agricultural monitoring, meteorology, security and inspection, exploration, and surveying, where real-time transmission is required. Drones cannot provide highly stable and high-quality aerial videos and photos, thus affecting their effectiveness.

[0003] Optical fiber, as the transmission medium for fiber optic communication, is immune to electromagnetic interference, making its combination with drones an innovative technology. This technology uses optical fiber as a high-speed, low-latency data transmission medium, ensuring that drone control signals are unaffected by external environmental and electromagnetic interference, and that high-definition video signals captured are transmitted back to the ground control station in real time, providing an immersive flight experience. With its ultra-high bandwidth, strong anti-interference capabilities, and extremely low latency, fiber optic transmission significantly enhances the performance and application range of drones.

[0004] The optical fiber module, positioned between the UAV and the ground terminal, is fixed to the UAV using specialized fixtures. The fiber optic module has outlets at both ends, with connectors at both ends connecting to photoelectric conversion modules on the UAV and ground terminals respectively, converting the signals into electrical signals. These signals are then connected to the UAV and ground terminals via cables. The UAV is responsible for converting video signals captured by its camera, as well as UAV attitude and payload status signals, into optical signals and transmitting them to the ground via the fiber optic cable. The ground terminal converts the optical signals back into electrical signals and decodes the video signals for display. Simultaneously, the ground terminal converts flight control signals into optical signals and transmits them to the UAV via the fiber optic cable; the UAV then converts these optical signals back into electrical signals to control the UAV's attitude and payload status. Fiber optic transmission not only supports high-definition and even ultra-high-definition video transmission but also effectively resists electromagnetic interference, ensuring stable signal transmission.

[0005] like Figure 1As shown, traditional fiber optic modules have a front-to-back fiber output design. The exposed fiber at the rear of the module connects to a coupler on the optoelectronic conversion module mounted on the drone via a fiber optic connector, and the two are tightly coupled together by threads. Because the rear of the fiber optic module faces forward during flight, the exposed fiber is susceptible to wind damage, posing a risk of fiber breakage and connector damage or failure. This affects normal signal transmission. Furthermore, each module is separate, taking up considerable space, and the cables connecting them often create a messy layout, further encroaching on the drone's limited space. Fiber optic modules are typically fixed to the drone using specialized fixtures, which are time-consuming and labor-intensive to install and remove. While some methods use tape or cable ties for securing the modules, these are unreliable and pose a risk of detachment during flight. Moreover, neither of these methods provides bottom support, requiring the drone to be placed on a supported surface for takeoff.

[0006] Therefore, to solve the above problems, an optoelectronic integrated conversion module was designed that occupies less space in the drone and can be quickly installed. Summary of the Invention

[0007] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0008] The technical problem to be solved by this invention is how to solve the problem of fiber breakage due to wind force affecting the normal transmission of signals during the flight of a drone.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an optoelectronic integrated conversion module for unmanned aerial vehicles (UAVs), comprising the UAV to which it is applied, wherein the optoelectronic integrated conversion module is composed of an optical fiber module and an optoelectronic conversion module, wherein the optoelectronic conversion module is disposed at the fiber output end of the optical fiber module, such that both ends of the optical fiber in the optical fiber module exit from the same end, one end of the optoelectronic conversion module is connected to the optical fiber module, the other end of the optoelectronic conversion module is connected to the electrical signal interface of the UAV, and the other end of the optical fiber module is connected to the optoelectronic component at the ground end.

[0010] As a preferred embodiment of the optoelectronic integrated conversion module for UAVs described in this invention, the optical fiber module includes an outer cylinder, an inner core, a fiber outlet tube, and a fiber outlet nozzle. The inner core is disposed inside the outer cylinder and includes a first baffle, a rewound optical fiber, and a second baffle. The rewound optical fiber is disposed between the first baffle and the second baffle. The second baffle is disposed on the outer cylinder. The fiber outlet tube is disposed on the second baffle, and the fiber outlet nozzle is disposed on the fiber outlet tube, thus forming a preliminary optical fiber module (excluding optical fiber connectors at both ends of the optical fiber).

[0011] As a preferred embodiment of the photoelectric integrated conversion module for UAVs described in this invention, the outer cylinder is a cylindrical structure with an open front end and a hollow interior. The bottom of the outer cylinder is provided with an inner convex ring for supporting the first baffle so as to press the inner core and the outer cylinder together. Six protruding first holes are evenly distributed on the side of the open end of the outer cylinder so as to connect and fix the components.

[0012] As a preferred embodiment of the optoelectronic integrated conversion module for UAVs described in this invention, the first baffle and the second baffle are both circular plate structures. A first through hole is opened in the center of both the first baffle and the second baffle. Six annular grooves that cooperate with the first post are symmetrically arranged on the outer wall of the second baffle. A fiber outlet is opened near the annular groove of the second baffle so that one end of the rewound optical fiber can pass through. A plurality of first mounting holes are evenly opened near the first through hole of the second baffle. A second mounting hole that cooperates with the first mounting hole is opened at one end of the fiber outlet tube so that the fiber outlet tube can be fixedly installed on the second baffle by screws.

[0013] As a preferred embodiment of the photoelectric integrated conversion module for UAVs described in this invention, the photoelectric conversion module includes a bottom shell, a photoelectric conversion component, and a cover plate. The bottom shell is disposed on the optical fiber module, the photoelectric conversion component is disposed inside the bottom shell, and the cover plate is disposed on the bottom shell.

[0014] As a preferred embodiment of the optoelectronic integrated conversion module for UAVs described in this invention, the bottom shell is in the shape of a cylinder with one side cut off. A second through hole is provided in the center of the bottom shell. A fiber optic tube is provided on the outer edge of the second through hole to wind excess optical fiber. Four positioning holes are evenly distributed on the outer side wall of the bottom shell to install the bottom shell onto the second baffle. A waist hole is provided on the inner wall of the bottom shell so that one end of the rewound optical fiber can be inserted into the bottom shell. A plurality of second holes are provided on the inner bottom wall of the bottom shell. A third mounting hole that mates with the second holes is provided on the cover plate.

[0015] As a preferred embodiment of the photoelectric integrated conversion module for UAVs described in this invention, the outer cylinder is provided with symmetrical balance bars on its upper and lower sides to provide a certain degree of support.

[0017] The beneficial effects of this invention are as follows: by integrating the optical fiber module and the photoelectric conversion module into a single structure, both ends of the optical fiber in the optical fiber module exit from the same end, thereby avoiding the damage to the exposed optical fiber at the front end due to wind force during the flight of the UAV, which would affect the normal transmission of the signal.

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0039] Figure 1 As is the existing technology, the fiber optic module 2 uses the traditional front and rear cable output method. The fiber optic cable exposed at the rear end of the fiber optic module 2 is connected to the coupler 9 on the optoelectronic conversion module mounted on the UAV 1 through the connected fiber optic connector 7. The two are tightly coupled together by threads. Because the rear end of the fiber optic module 2 faces forward during flight, the exposed fiber optic cable is subject to the influence of wind, which may cause the fiber to break, the fiber optic connector 7 to be damaged or malfunction, thus affecting the normal transmission of the signal.

[0040] The fiber optic module 2 fixed on the drone 1 is cylindrical in shape. Currently, the fixation to the drone 1 is done by either using cable ties 8 or tape to bind the fiber optic module 2 to the bottom of the drone 1, or by adding a clamp to the bottom of the drone 1 and tightening the outer shell of the fiber optic module 2 with bolts. The former is not secure due to the shape of the fiber optic module 2 and there is a risk of it falling off during flight. The latter requires professional tools and is time-consuming and laborious to install and remove. Both have the same drawback: after loading the fiber optic module 2 to the bottom of the drone 1, there is no support at the bottom. The bottom of the drone 1 must be placed on a supported flat surface before it can take off.

[0041] Example

[0042] Reference Figures 2-16 This embodiment provides an integrated optoelectronic conversion module for a drone 1, including the drone 1 to which it is applied. The integrated optoelectronic conversion module consists of an optical fiber module 2 and an optoelectronic conversion module 3. The optoelectronic conversion module 3 is disposed at the fiber output end of the optical fiber module 2, so that both ends of the optical fiber in the optical fiber module 2 exit from the same end. One end of the optoelectronic conversion module 3 is connected to the optical fiber module 2, and the other end of the optoelectronic conversion module 3 is connected to the electrical signal interface of the drone 1. The other end of the optical fiber module 2 is connected to the optoelectronic component at the ground end.

[0043] The optoelectronic conversion module in this embodiment is mainly used on the UAV 1. It mainly consists of an optical fiber module 2 and an optoelectronic conversion module 3. The optoelectronic conversion module 3 is integrated into the fiber output end of the optical fiber module 2, so that both ends of the optical fiber in the optical fiber module 2 exit from the same end. This avoids the risk of the optical fiber being exposed on the outside of the UAV 1 and broken due to wind when it is connected to the optoelectronic conversion module 3 on the UAV 1, thus ensuring normal signal transmission. One end of the optoelectronic conversion module 3 is connected to the optical fiber module 2 through an optical fiber connector 7, and the other end of the optoelectronic conversion module 3 is connected to the electrical signal interface of the UAV 1 through a communication cable assembly. The other end of the optical fiber module 2 is connected to the optoelectronic component on the ground end through an optical fiber connector 7, so as to realize a stable connection between the UAV 1, the optoelectronic conversion module and the ground end.

[0044] Specifically, the fiber optic module 2 includes an outer cylinder 21, an inner core 22, a fiber outlet tube 23, and a fiber outlet nozzle 24. The inner core 22 is disposed inside the outer cylinder 21. The inner core 22 includes a first baffle 221, a rewound fiber 222, and a second baffle 223. The rewound fiber 222 is disposed between the first baffle 221 and the second baffle 223. The second baffle 223 is disposed on the outer cylinder 21. The fiber outlet tube 23 is disposed on the second baffle 223, and the fiber outlet nozzle 24 is disposed on the fiber outlet tube 23.

[0045] In this embodiment, the optical fiber module 2 mainly consists of an outer cylinder 21, an inner core 22, a fiber outlet tube 23, and a fiber outlet nozzle 24. The inner core 22 is installed inside the outer cylinder 21. The inner core 22 mainly consists of a first baffle 221, a rewound optical fiber 222, and a second baffle 223. The rewound optical fiber 222 is fixed on the optical fiber rewinding machine by the first baffle 221 and the second baffle 223, and the optical fiber is wound into a cylinder with a through hole in the middle of the two. It is then fixed with glue to a semi-solid state to make it the inner core 22. The second baffle 223 is installed on the outer cylinder 21. The fiber outlet tube 23 is installed on the second baffle 223. The fiber outlet nozzle 24 is fixedly installed at the end of the fiber outlet tube 23 away from the second baffle 223 to form a preliminary optical fiber module 2 (excluding the optical fiber connectors 7 at both ends of the optical fiber). The optical fiber inside the inner core 22 can be led out through the fiber outlet tube 23 and the fiber outlet nozzle 24.

[0046] Furthermore, the outer cylinder 21 has a cylindrical structure with an open front end and a hollow interior. The bottom of the outer cylinder 21 is provided with an inner convex ring 211 for supporting the first baffle 221. Six protruding first hole columns 212 are evenly distributed on the side of the open end of the outer cylinder 21.

[0047] In this embodiment, the outer cylinder 21 is designed as a cylindrical structure with an open front end and a hollow interior, so that the inner core 22 can be inserted into the outer cylinder 21. An inner protruding ring 211 is provided at the bottom of the outer cylinder 21 to support the first baffle 221, so as to press the inner core 22 and the outer cylinder 21 together. Six protruding first hole posts 212 are evenly distributed on the side of the open end of the outer cylinder 21, so as to fix and connect the other components through the first hole posts 212.

[0048] Furthermore, both the first baffle 221 and the second baffle 223 are circular plate structures. The center of both the first baffle 221 and the second baffle 223 is provided with a first through hole 2231. The outer wall of the second baffle 223 is symmetrically provided with six annular grooves 2232 that cooperate with the first hole post 212. The second baffle 223 is provided with a fiber outlet 2233 near the annular grooves 2232. The second baffle 223 is provided with a plurality of first mounting holes 2234 evenly near the first through hole 2231. One end of the fiber outlet tube 23 is provided with a second mounting hole 231 that cooperates with the first mounting hole 2234.

[0049] In this embodiment, both the first baffle 221 and the second baffle 223 are designed as circular plates to better clamp and fix the rewound optical fiber 222. A first through hole 2231 is provided at the center of both the first baffle 221 and the second baffle 223 to facilitate winding and leading out the optical fiber. Six annular grooves 2232, which mate with the first post 212, are symmetrically arranged on the outer wall of the second baffle 223 to fix the second baffle 223 onto the outer cylinder 21. A fiber outlet 2233 is provided near the annular grooves 2232 on the second baffle 223 to allow the optical fiber on the outer side of the inner core 22 to pass through. Four first mounting holes 2234 are evenly provided on the second baffle 223 near the first through hole 2231. A second mounting hole 231, which mates with the first mounting holes 2234, is provided on one end of the fiber outlet tube 23 to fix the fiber outlet tube 23 with screws. On the second baffle 223, the first through hole 2231 on the second baffle 223 is connected to the fiber outlet tube 23, so that the optical fiber inside the inner core 22 passes through the first through hole 2231 on the second baffle 223 and enters the fiber outlet tube 23. It is then led out by the fiber outlet nozzle 24 on the fiber outlet tube 23 and finally connected to the optoelectronic component at the ground end through the optical fiber connector 7. In this embodiment, the fiber outlet tube 23 of the existing optical fiber module 2 is cleverly integrated with the optoelectronic conversion module 3, so that the optical fibers at both ends of the optical fiber module 2 exit from the same end. One end of the optical fiber inside the inner core 22 exits from the first through hole 2231 of the second baffle 223, and one end of the optical fiber outside the inner core 22 exits from the fiber outlet 2233 of the second baffle 223. The optoelectronic conversion module 3 with the outer shell removed is integrated with the optical fiber tube, thereby avoiding the optical fiber exposed at the front end from being broken due to wind force during the flight of the UAV 1, which would affect the normal transmission of the signal.

[0050] Specifically, the photoelectric conversion module 3 includes a bottom shell 31, a photoelectric conversion component 32, and a cover plate 33. The bottom shell 31 is disposed on the optical fiber module 2, the photoelectric conversion component 32 is disposed inside the bottom shell 31, and the cover plate 33 is disposed on the bottom shell 31.

[0051] The photoelectric conversion module 3 mainly consists of a bottom shell 31, a photoelectric conversion component 32, and a cover plate 33. The bottom shell 31 is installed on the second baffle 223 of the fiber optic module 2. The photoelectric conversion component 32 is installed inside the bottom shell 31. The cover plate 33 is also installed on the bottom shell 31 to provide a certain degree of protection, so as to prevent dust from entering the bottom shell 31 after outdoor use and affecting subsequent normal use. In this embodiment, the photoelectric conversion module 3 is integrated into the excess space in the direction of the fiber outlet tube 23 of the fiber optic module 2, so that the photoelectric conversion module 3 and the fiber optic module 2 are combined into an integrated module. That is, photoelectric conversion is performed directly in the integrated module. It is connected to the UAV 1 end through the communication cable assembly, without the fiber optic cable being exposed on the outside and connected to the UAV 1 end. This not only makes disassembly and assembly convenient, but also avoids the risk of fiber breakage caused by wind during the flight of the UAV 1. At the same time, since the connection between the photoelectric conversion module 3 and the fiber optic module 2 is completed in the bottom shell 31, the overall wiring is more reasonable and the space occupied by the photoelectric conversion module 3 and the fiber optic module 2 is reduced.

[0052] Furthermore, the bottom shell 31 is in the shape of a cylinder with one side cut off. A second through hole 311 is opened in the center of the bottom shell 31. A fiber tube 312 is provided on the outer edge of the second through hole 311. Four positioning holes 313 are evenly distributed on the outer side wall of the bottom shell 31. A waist hole 314 is opened on the inner wall of the bottom shell 31. Several second holes 315 are provided on the inner bottom wall of the bottom shell 31. A third mounting hole 331 that mates with the second holes 315 is opened on the cover plate 33.

[0053] In this embodiment, the bottom shell 31 is designed as a cylindrical shape with one side cut off to facilitate the installation of the photoelectric conversion component 32. A slot is provided on the cut-off side of the bottom shell 31 to mate with the electrical signal interface of the photoelectric conversion component 32. A second through hole 311 is provided in the center of the bottom shell 31 to allow the fiber optic tube 23 to pass through it. A fiber optic winding tube 312 is provided on the outer edge of the second through hole 311 to wind excess optical fiber. Four positioning posts 313 are evenly distributed on the outer wall of the bottom shell 31 to mount the bottom shell 31 onto the second baffle 223. The inner wall of the device has a waist hole 314 so that the optical fiber led out from the fiber outlet 2233 can pass through the waist hole 314 into the bottom shell 31 and be connected to the photoelectric conversion component 32 through the optical fiber connector 7. Five second hole posts 315 are provided on the inner bottom wall of the bottom shell 31. Two third mounting holes 331 that cooperate with the second hole posts 315 are provided on the cover plate 33. Three second hole posts 315 are used to fix the photoelectric conversion component 32, and the other two are used to fix the cover plate 33. It should be noted that the center of the cover plate 33 also has a through hole for the fiber outlet tube 23 to pass through.

[0054] Furthermore, balance bars 4 are symmetrically arranged on the upper and lower sides of the outer cylinder 21.

[0055] This embodiment also features four balance bars 4 symmetrically installed on the upper and lower sides of the outer cylinder 21. When the optoelectronic conversion module is installed to the UAV 1 using cable ties 8 or tape, the balance bars 4 on the outer cylinder 21 can be attached to the bottom surface of the UAV 1 to increase the reliability of the connection between the optoelectronic conversion module and the UAV 1. Furthermore, when the UAV 1 takes off and lands, the balance bars 4 can directly contact the ground, providing a certain degree of balance support.

[0056] Furthermore, the drone 1 is equipped with a bracket 5, the bottom of the bracket 5 is equipped with a support leg 6, and the bottom of the outer cylinder 21 is equipped with a blind hole 213 that cooperates with the bracket 5.

[0057] like Figure 14 As shown, in other embodiments, brackets 5 can be symmetrically installed at the bottom of the drone 1, and blind holes 213 that cooperate with the brackets 5 can be provided at the bottom of the outer cylinder 21. One end of the brackets 5 is connected to the bottom of the outer cylinder 21 by screws, and the other end of the brackets 5 can be synchronously fixedly installed on the bottom shell 31 of the photoelectric conversion module 3, thereby increasing the reliability of the connection between the outer cylinder 21 and the drone 1. In addition, a foot 6 is provided at the bottom of the brackets 5 to provide a certain support function, so as to facilitate the take-off and landing of the drone 1.

[0058] In use, firstly, one end of the optical fiber inside the inner core 22 exits from the first through hole 2231 of the second baffle 223, and one end of the optical fiber outside the inner core 22 exits from the fiber outlet 2233 of the second baffle 223. Then, place the entire inner core 22 into the outer cylinder 21. Next, pass one end of the optical fiber inside the inner core 22 through the fiber outlet tube 23 and lead it out from the fiber outlet nozzle 24. Then, install the fiber outlet tube 23 onto the second baffle 223 with screws. Finally, pass one end of the optical fiber exiting from the fiber outlet 2233 through the waist hole 314 on the bottom shell 31 into the bottom shell 31. Inside the fiber optic module 2, a fiber optic connector 7 is fabricated at the end of the fiber optic cable. Excess fiber optic cable is wound around the outer wall of the fiber optic tube 312. The fiber optic connector 7 is inserted into the optical port of the pre-installed photoelectric conversion component 32, and the signal is converted from photoelectric to electrical signal. The cover plate 33 is installed and fastened to the bottom shell 31 with screws. After installation, the bottom shell 31 and the second baffle 223 are installed together into the first hole post 212 of the outer cylinder 21 with bolts, so that the photoelectric conversion module 3 is completely installed on the fiber optic module 2. The fiber optic cable leading out from the fiber outlet 24 is fused with light. The pigtail of fiber optic connector 7, or directly as fiber optic connector 7, forms an integrated optoelectronic conversion module. After the integrated optoelectronic conversion module is assembled, it can be fixed to the UAV 1 end by cable ties 8, tape, or bracket 5. The electrical signal interface on the integrated optoelectronic conversion module is connected to the electrical signal interface on the UAV 1 end through a communication cable assembly. The optical fiber led out from the fiber outlet 24 of the integrated optoelectronic conversion module is connected to the optoelectronic component at the ground end through the fiber optic connector 7. During flight, the UAV 1 end is responsible for converting the video signal captured by the camera on the UAV 1, the attitude and load status signals of the UAV 1 into optical signals, and transmitting them to the ground end through optical fiber. The ground end is responsible for converting the optical signals back into electrical signals and decoding the video signals to display on the screen. At the same time, the ground end is responsible for converting the flight control signals into optical signals and transmitting them to the UAV 1 end through optical fiber. The UAV 1 end is responsible for converting the optical signals back into electrical signals and controlling the attitude and load status of the UAV 1. Fiber optic transmission not only supports high-definition and even ultra-high-definition video transmission, but also effectively resists electromagnetic interference and ensures stable signal transmission.

[0059] After the flight ends, the drone 1 lands, and the communication cable assembly between the drone 1 and the optoelectronic conversion module is removed. The cable ties 8 or tape binding the drone 1 and the optoelectronic conversion module are cut off, or the optoelectronic conversion module is loosened from the bracket 5 at the drone 1 end. The bolts on the outer cylinder 21 and the optoelectronic conversion module 3 can be loosened to quickly separate the two. The cover plate 33 on the optoelectronic conversion module 3 is removed, and the outer optical fiber inside the new optical fiber module 2 is led out through the fiber outlet 2233 and inserted through the waist hole 314 on the bottom shell 31 of the optoelectronic conversion module 3. An optical fiber connector 7 is made on the optical fiber or fused together with the original cable. The cover plate 33 is then put back on and secured. The optical fiber at the other end of the outer cylinder 21 is led out through the fiber outlet 24.
