Description

Technical Field

[0001] This utility model relates to the technical field of devices for unmanned aerial vehicle (UAV) flight experiments, and in particular to a large-space, highly retractable protective structure for UAV flight experiments. Background Technology

[0002] The large-space, highly retractable protective structure used in drone flight experiments is designed to ensure the safe flight of drones during experiments and to prevent collisions or damage to the drones with the environment or personnel. At the same time, it provides sufficient space for the experiments. With the continuous development of drone technology, especially its widespread application in industry, agriculture, scientific research and other fields, flight experiments have become increasingly important. Therefore, designing and manufacturing an efficient and safe protective structure is particularly important.

[0003] Conventional large protective frames are usually integral welded structures, which are bulky and difficult to store and fold. They occupy laboratory space for a long time, making it inconvenient to quickly change experimental sites. Moreover, the entire process from setting up the environment to debugging the equipment is too time-consuming, which compresses the effective working time of the R&D team. Each time the test site is changed, the layout needs to be replanned, which slows down the project. At the same time, existing protective nets mostly use bolt fastening or clamp clamping methods, which require tools to complete multi-point fixation. The steps are cumbersome and it is easy to miss key nodes. Especially in high-altitude operations or narrow environments, the operation difficulty is further increased, and it is not convenient to quickly load and unload. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a large-space, highly retractable protective structure for unmanned aerial vehicle (UAV) flight experiments.

[0005] This utility model is achieved using the following technical solution: a large-space, highly retractable protective structure for unmanned aerial vehicle (UAV) flight experiments, comprising a support base, a controller fixedly connected to the outside of the support base, a connecting shell fixedly connected to the top of the support base, a fixing block fixedly connected to the top of the connecting shell, and further comprising:

[0006] An expansion mechanism, comprising a threaded rod rotatably connected inside a connecting housing, the threaded rod having a sliding sleeve externally threadedly connected to it;

[0007] The protective mechanism includes an insert block fixedly connected to the outside of a fixed block, an outer casing sleeved around the insert block, and a protective net fixedly connected to the bottom of the outer casing.

[0008] As a further improvement to the above solution, a synchronous motor is fixedly connected to the left side of the support base, and a rotating rod is fixedly connected to the output end of the synchronous motor. The rotating rod is rotatably connected inside the support base.

[0009] The above technical solution provides a standardized power source for the entire expansion mechanism, ensuring controllable speed and stable torque, avoiding the inefficiency and human error of traditional manual operation, and enabling spatial adjustment.

[0010] As a further improvement to the above solution, a first bevel gear is fixedly connected to the outside of the rotating rod, and a second bevel gear is fixedly connected to the outside of the threaded rod.

[0011] The above technical solution, through the vertically interlocking bevel gear meshing design, efficiently converts horizontal rotational motion into vertical linear driving force, optimizes the transmission path and reduces energy loss, and improves the accuracy and response speed of space expansion.

[0012] As a further improvement to the above solution, the first bevel gear and the second bevel gear mesh with each other, the sliding sleeve is slidably connected inside the connecting housing, and the sliding sleeve is rotatably connected to the first connecting rod inside.

[0013] As a further improvement to the above solution, the fixed block is internally rotatably connected to a second link, and the first link is rotatably connected inside the second link.

[0014] Through the above technical solutions, the first link and the second link can enhance the structural rigidity while achieving a large-scale spatial expansion and increasing the internal space.

[0015] As a further improvement to the above solution, a pull block is slidably connected inside the mounting housing, and a limit block is fixedly connected to the bottom of the pull block, with the limit block slidably connected inside the mounting housing.

[0016] The above technical solution provides users with an intuitive operating handle, enabling the positioning and pre-setting of the protective net through linear traction, reducing the probability of misoperation and improving the human-machine interaction friendliness of the safety protection device deployment.

[0017] As a further improvement to the above solution, a limiting rod is fixedly connected inside the mounting housing, a limiting block is slidably connected to the outside of the limiting rod, and a spring is fixedly connected to the left side of the limiting block, with the spring fixedly connected between the limiting block and the mounting housing.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention utilizes a transmission system composed of a synchronous motor, a rotating rod, a first bevel gear, a second bevel gear, a threaded rod, a sliding sleeve, a first connecting rod, and a second connecting rod to work in synergy. This system dynamically adjusts and expands the distance between the support bases, thereby increasing the experimental space. This mechanical linkage design not only allows for rapid response to operational needs and expands the space, providing a suitable flight environment for UAVs, but also significantly improves the adaptability and versatility of the device to diverse experimental scenarios. Furthermore, it facilitates storage and arrangement, reducing the time required for site setup when experiments are needed and improving experimental efficiency.

[0020] This utility model utilizes a self-locking installation structure consisting of a pull block, a limit block, a limit rod, a spring, and an insert block to facilitate the convenient fixing and stable connection of the protective net. This achieves efficient assembly and reliable locking of the safety protection components. The design utilizes the elastic reset characteristics of the spring to achieve automatic locking, which simplifies the operation process and effectively resists vibration interference through a mechanical interlocking mechanism, ensuring the long-term stability of the protective net under complex working conditions and significantly reducing the safety risks caused by accidental loosening.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-6 This embodiment of a large-space, highly retractable protective structure for unmanned aerial vehicle (UAV) flight experiments includes a support base 1, a controller 11 fixedly connected to the outside of the support base 1, a connecting shell 12 fixedly connected to the top of the support base 1, a fixing block 13 fixedly connected to the top of the connecting shell 12, and further includes:

[0032] Expansion mechanism 2 includes a threaded rod 204 rotatably connected inside the connecting housing 12, and a sliding sleeve 206 is externally threaded to the threaded rod 204.

[0033] The protective mechanism 3 includes an insert block 301 fixedly connected to the outside of the fixed block 13. An installation shell 302 is sleeved on the outside of the insert block 301, and a protective net 307 is fixedly connected to the bottom of the installation shell 302.

[0034] A synchronous motor 201 is fixedly connected to the left side of the support base 1. A rotating rod 202 is fixedly connected to the output end of the synchronous motor 201. The rotating rod 202 is rotatably connected inside the support base 1.

[0035] The rotating rod 202 is externally fixedly connected to a first bevel gear 203, and the threaded rod 204 is externally fixedly connected to a second bevel gear 205.

[0036] The first bevel gear 203 and the second bevel gear 205 mesh with each other, and the sliding sleeve 206 is slidably connected inside the connecting housing 12. The first connecting rod 207 is rotatably connected inside the sliding sleeve 206.

[0037] The second link 208 is rotatably connected inside the fixed block 13, and the first link 207 is rotatably connected inside the second link 208.

[0038] The mounting housing 302 has a sliding connection of a pull block 303 inside, and a limit block 304 is fixedly connected to the bottom of the pull block 303. The limit block 304 is slidably connected inside the mounting housing 302.

[0039] The mounting housing 302 is internally fixedly connected to a limiting rod 305, and a limiting block 304 is slidably connected to the outside of the limiting rod 305. A spring 306 is fixedly connected to the left side of the limiting block 304, and the spring 306 is fixedly connected between the limiting block 304 and the mounting housing 302.

[0040] The implementation principle of a large-space, high-retractability protective structure for UAV flight experiments in this application embodiment is as follows: Before use, the synchronous motor 201 is started. After the synchronous motor 201 is started, the rotating rod 202 at its output end begins to rotate counterclockwise and drives the first bevel gear 203 connected to it to rotate counterclockwise. Since the first bevel gear 203 and the second bevel gear 205 are meshed, this transmission relationship causes the second bevel gear 205 to rotate synchronously in the clockwise direction. Then, the threaded rod 204 fixed inside the second bevel gear 205 also rotates and pushes the sliding sleeve 206 to rise smoothly along the connecting shell 12. During this process, the first connecting rod 207 inside the sliding sleeve 206 is driven to rotate and drives the second connecting rod 208 inside the fixed block 13 to rotate. This series of actions eventually makes the distance between the support bases 1 gradually increase, forming a spacious internal space that meets the experimental requirements.

[0041] At this time, the user can gently pull the pull block 303 inside the mounting housing 302. Since the limiting block 304 is fixedly connected to the bottom of the pull block 303 and the limiting block 304 is slidably set inside the mounting housing 302, it moves smoothly under the action of pulling force. At the same time, the limiting rod 305 inside the mounting housing 302 provides accurate guidance for the limiting block 304, ensuring the stability of the movement trajectory. Meanwhile, the spring 306 connected between the left side of the limiting block 304 and the mounting housing 302 is under pressure. When the mounting housing 302 is pulled to the bottom position, it can be accurately fitted onto the insert block 301 outside the fixing block 13. At this time, the pull block 303 is released, and under the elastic force of the spring 306, the limiting block 304 will automatically insert into the insert block 301, forming a reliable positioning and locking structure. This design not only ensures the convenience of installing the protective net 307, but also ensures the stability of the connection through mechanical locking, effectively preventing the risk of falling off due to accidental vibration.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
