Description

Technical Field

[0001] This utility model relates to the technical field of data transmission, and in particular to a structure for optical fiber data transmission. Background Technology

[0002] In the field of machinery and equipment in the low-altitude industry, the application of data transmission technology is crucial. Currently, wireless network transmission is the main method of data transmission in the low-altitude industry and is widely used in equipment such as drones.

[0003] However, wireless network transmission has many shortcomings in actual use. First, due to the complexity of the usage environment, such as enclosed spaces or areas with signal obstruction, wireless signals are easily interfered with or even lost, resulting in unstable data transmission. Second, the effective distance of wireless transmission is limited, making it difficult to meet the needs of long-distance application scenarios. In addition, wireless network transmission also faces problems such as signal strength fluctuations and data transmission delays, which directly affect the reliability and efficiency of device operation.

[0004] With the rapid development of the low-altitude economy, higher demands are being placed on data transmission technology, especially in terms of signal stability, anti-interference capabilities, and transmission distance. Fiber optic transmission, as an efficient data transmission method, can effectively solve these problems. Fiber optic transmission has advantages such as high bandwidth, low latency, strong anti-interference capabilities, and long-distance transmission, making it very suitable for complex scenarios in the low-altitude industry. However, the application of fiber optic transmission in the low-altitude industry is still in its early stages. Existing technologies lack a design that can efficiently integrate fiber optic transmission structures to meet the data transmission needs of devices such as drones in dynamic environments. Therefore, an innovative fiber optic data transmission structure design is urgently needed that can fully leverage the technological advantages of fiber optic transmission while overcoming the shortcomings of existing wireless network transmission, thereby improving the overall performance and reliability of equipment in the low-altitude industry.

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a structure for optical fiber data transmission, addressing the problems of signal interference, unstable signal strength, and limited transmission distance that exist in existing low-altitude industrial data transmission methods that mainly rely on wireless network transmission.

[0006] The technical problem solved by this utility model is achieved through the following technical solution:

[0007] A fiber optic data transmission structure includes a fiber optic tube and a fiber optic shaft. One end of the fiber optic tube is open, and one end of the fiber optic shaft is provided with a cover plate. When the fiber optic shaft is inserted into a designated position inside the fiber optic tube, the cover plate blocks the open end of the fiber optic tube. An optical fiber is wound on the fiber optic shaft. One end of the optical fiber passes through the end of the fiber optic tube away from the open end, and the other end of the optical fiber extends through the cover plate to the outside of the fiber optic tube. That is, the fiber optic data transmission structure is fixed on a drone, with one end of the optical fiber connected to the drone and the other end connected to a signal transceiver device, thereby using the optical fiber for data transmission.

[0008] Furthermore, it also includes a cable guide tube and a bend transition tube. The end of the fiber optic tube away from the through end has a protrusion. One end of the cable guide tube is connected to the protrusion through the bend transition tube, and the other end of the cable guide tube is provided with a cable guide nozzle.

[0009] Furthermore, the optical fiber shaft includes a straight section and a horn section. One end of the straight section is connected to a small opening in the horn section, and the other end is connected to a cover plate. The cover plate is provided with a wire threading port.

[0010] Furthermore, a winding seat is provided on the side of the cover plate facing away from the optical fiber tube.

[0011] Furthermore, the optical fiber tube is provided with a support member, one end of which passes through the optical fiber tube and extends into the optical fiber tube.

[0012] Furthermore, the support member is provided with a notch, and when the optical fiber shaft extends into a designated position inside the optical fiber tube, the optical fiber shaft abuts against the notch.

[0013] Furthermore, the protruding nozzle is located on the axis of the optical fiber tube, and a wire guide rounded corner is provided between the optical fiber tube and the protruding nozzle.

[0014] Furthermore, the outer surface of the horn segment includes interconnected inclined surfaces, guide circular surfaces, and straight surfaces.

[0015] Furthermore, the conduit and the bend transition pipe are connected by threads and coated with anti-loosening adhesive.

[0016] Furthermore, the cover plate is provided with screws for connecting to the optical fiber tube.

[0017] The advantages and positive effects of this invention are: it solves the problems of signal interference, unstable signal strength, and limited transmission distance in traditional wireless network transmission methods. Specifically, the use of optical fiber significantly improves the stability and anti-interference capability of data transmission, while extending the transmission distance. In addition, the design of the optical fiber data transmission structure fully considers the dynamic characteristics of UAVs during flight.

[0025] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0026] This utility model relates to an optical fiber data transmission structure, the specific implementation of which is as follows: Figure 1-3 As shown in the detailed description, this fiber optic data transmission structure is suitable for drone equipment in the low-altitude industry. It can solve the problems of signal interference, instability and limited transmission distance in the existing wireless network transmission. By adopting the combined design of components such as ceramic cable guide 1, cable guide tube 2, turning transition tube 3, fiber optic tube 4, fiber optic shaft 7, support 5 and screw 8, it ensures that the fiber optic cable achieves efficient and stable data transmission during the drone's flight.

[0027] like Figure 1As shown, the core components of the fiber optic data transmission structure include a ceramic cable guide 1, a cable guide tube 2, a bend transition tube 3, a fiber optic tube 4, a fiber optic shaft 7, a support 5, and screws 8. These components are assembled in a specific order to form a complete fiber optic data transmission system. The ceramic cable guide 1 is fixed at the outlet of the cable guide tube 2 to reduce friction and damage to the fiber optic cable during release. Ceramic material is selected due to its high hardness and wear resistance, and its surface is polished to reduce the coefficient of friction. The ceramic cable guide 1 and the cable guide tube 2 are fixed together with a high-strength adhesive, which cures for no less than 24 hours to ensure that the connection strength meets the dynamic requirements of the UAV during flight. The cable guide tube 2 and the bend transition tube 3 are connected by threads and coated with anti-loosening adhesive to enhance connection reliability. The tightening torque is 10 N·m. The bend transition tube 3 and the protrusion 10 on the outer shell of the fiber optic tube 4 are also connected by threads, and a positioning pin is inserted to ensure that the relative position between the two is accurate. The tightening torque is 15 N·m. This connection method is not only easy to disassemble and maintain, but also able to withstand the vibration and impact generated during UAV flight.

[0028] The design of the fiber optic tube 4 fully considers the storage and release requirements of the fiber optic cable. The left side of the outer shell of the fiber optic tube 4 is designed with a cable guide rounded corner 9 to ensure that the fiber optic cable can smoothly transition during the release process and avoid stress concentration caused by sharp bends. Four square holes are evenly distributed on the circumference of the fiber optic tube 4 body for installing the support member 5 of the fiber optic shaft 7, thereby supporting the fiber optic shaft 7 and keeping its position stable and without displacement. The support member 5 of the fiber optic shaft is made of high-strength engineering plastic and its cross-section is rectangular, which matches the square holes on the wall of the fiber optic tube 4.

[0029] After the support member 5 is inserted into the square hole, its outer end face contacts the fiber shaft 7 to form a point contact support, reducing wear on the fiber shaft 7. At the same time, the support member 5 is provided with a notch. When the fiber shaft is inserted into the designated position inside the fiber tube, the fiber shaft abuts against the notch to prevent the support member from loosening during use. The right side of the fiber tube 4 body is designed with a fiber shaft screw fixing end face, which is used to fix the fiber shaft 7 inside the fiber tube 4 by screws 8. The tightening torque is 5 N·m.

[0030] The structural design of the fiber optic shaft 7 takes into account both the winding and exit requirements of the fiber optic cable. The fiber optic shaft 7 includes a straight section 71 and a horn section 72. One end of the straight section 71 is connected to the small opening of the horn section 72, and the other end is connected to the cover plate 14. The cover plate 14 has a cable insertion port. The outer surface of the horn section includes interconnected inclined surfaces 11, guiding circular surfaces 12, and straight surfaces 13. The design of the straight surface 13 ensures that the fiber optic cable remains straight during initial exit, avoiding signal loss due to bending. The guiding circular surface 12 and the inclined surface 11 serve as buffers and guides, respectively, allowing the fiber optic cable to gradually change direction during release, reducing mechanical stress. The diameter of the straight section 71 is determined based on the minimum bending radius of the fiber optic cable. To ensure that the optical fiber is not damaged due to excessive bending during the winding process, a winding seat 15 is provided on the side of the cover plate 14 facing away from the optical fiber tube 4. The cover plate 14 and the winding seat 15 are used to fix the starting end and the end of the optical fiber, respectively, to prevent the optical fiber from tangling or knotting during use. The winding process of the optical fiber is completed by a special winding equipment. The winding equipment controls the winding speed and tension to ensure that the optical fiber maintains a uniform tension distribution during the winding process. After the winding is completed, the optical fiber shaft 7 is installed into the optical fiber tube 4 and locked in place by screws 8. The tightening torque of the screws 8 is precisely calculated to ensure that the optical fiber shaft 7 assembly in the optical fiber tube 4 will neither loosen nor be damaged due to excessive tightness.

[0031] One end of the fiber optic cable is connected to the data interface of the drone, and the other end is connected to the data interface of the signal transceiver, thereby enabling the transmission of data signals.

[0032] This invention significantly improves the stability and anti-interference capability of data transmission through the above-mentioned technical solution, while extending the transmission distance. The use of optical fiber solves the problems of signal interference, unstable signal strength, and limited transmission distance in traditional wireless network transmission methods. In addition, the design of the optical fiber data transmission structure fully considers the dynamic characteristics of UAVs during flight. Through the synergistic effect of components such as ceramic cable guide 1, optical fiber tube 4, and optical fiber shaft 7, it ensures that the optical fiber maintains a good physical state during release and retrieval, thereby reducing maintenance costs and usage risks. By optimizing the material selection and structural design of each component, the overall structure is made lightweight and compact, making it suitable for various low-altitude industry applications such as UAV inspection, logistics distribution, and environmental monitoring, providing reliable technical support for the development of the low-altitude economy.

[0033] It should be emphasized that the embodiments described in this utility model are illustrative and not limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
