[0002] With the rapid development of drone technology, drones are increasingly used in various fields, especially in field data acquisition, environmental monitoring, resource survey and other tasks. With their high efficiency and flexibility, drones play an irreplaceable role. However, when performing these tasks, drones often face the challenge of power limitations. Since existing drone batteries mostly use non-detachable connections or complex disassembly processes, it is impossible to quickly and effectively replace the battery when the drone runs out of power, which greatly limits the operation time and efficiency of the drone.

[0003] Specifically, existing drone battery designs usually tightly fix the battery to the drone body, forming an irremovable connection. Although this design improves the compactness and stability of the drone, it brings great inconvenience in battery replacement. Once the drone runs out of power, professionals need to use special tools to disassemble and replace it, which is not only time-consuming and labor-intensive, but also increases maintenance costs.

[0004] Therefore, the existing drone battery design cannot meet the needs of automated battery replacement. This limitation is particularly prominent in scenarios such as large-scale cluster measurement that require a large number of drones to work together. Frequent manual battery replacement not only reduces work efficiency, but also increases safety risks. Utility Model Content

[0028] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0029] See also Figures 1 to 8 . It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0030] The following embodiments are only for illustration purposes and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0031] For this example, please refer to Figure 1The utility model provides a battery embodiment, including a gold finger 20 and a limiting structure, the gold finger 20 is arranged at the bottom of the battery head end, the limiting structure includes a first limiting structure and a second limiting structure, the first limiting structure is arranged on both sides of the battery head end, the first limiting structure is a concave limiting hole 21, the second limiting structure is arranged on both sides of the battery tail end, and the second limiting structure is a protruding limiting strip 22.

[0032] The gold finger 20 is used to achieve electrical connection with the drone or charger. The gold finger is composed of a large number of conductive contacts, and its surface can be gold-plated to achieve oxidation resistance and improve conductivity, so as to ensure that the battery replacement process is not easy to wear and tear, and to ensure the stability of power supply and signal transmission. After the limit bar 22 matches the slot on the drone, the battery can only slide along the limit bar 22, so that the battery can be pulled out of the drone body, or the battery can be pushed into the drone body. This method makes the angle at which the battery is installed in the drone unique, so that the connection method of the battery's gold finger 20 to the electrode connector of the drone or charger can be carried out at the expected angle, achieving the effect of only plugging and unplugging from a single direction. Once the battery is inserted into the drone, the limit structure in the drone body is inserted into the limit hole 21, and then the battery can be completely fixed on the drone body. When the battery needs to be removed, the limit structure in the drone body is first withdrawn from the battery limit hole 21, and then the battery can be pulled out, but it can only be pulled out along the limit bar 22 to avoid damage to the gold finger due to unexpected pull-out direction. The solution of the above embodiment has the characteristics of reliable limiting, simple disassembly, and unique removal and installation angles of the battery, which significantly improves the stability of the battery structure and electrical connection.

[0033] Furthermore, a concave cavity is provided at the top of the rear end of the battery, and a grabbing shaft 23 is provided in the concave cavity. The function of the grabbing shaft 23 is to facilitate the battery replacement machine to grab and clamp the battery, so as to facilitate the realization of automated battery replacement. The material of the grabbing shaft 23 can be a metal that can be adsorbed by a magnet, and the clamping mechanism can use magnetic suction to simplify the claw structure. The grabbing shaft 23 is set at the tail end to facilitate pulling the battery out of the drone or pushing the battery into the drone body.

[0034] See also Figure 2 An embodiment of a drone is matched with the above-mentioned battery. A concave cavity is set on the top of the drone body. The shape of the concave cavity matches the battery. The concave cavity has an electrical connection terminal 10 that matches the battery gold finger 20. The side of the concave cavity has a groove 11 that matches the battery limit strip 22. The side of the concave cavity also has a limit column 202 that can be inserted into or pulled out of the battery limit hole 21.

[0035] In specific implementation, a sealing strip can be provided at the contact part between the battery and the drone, especially above the gold finger. When the battery is pushed into the drone body, the sealing strip is automatically compressed to prevent moisture from accumulating and entering the gold finger when the drone is operating in the air. The above combination of drone and battery has the characteristics of reliable battery fixation and convenient assembly and disassembly, which is particularly suitable for scenarios requiring automated battery replacement.

[0036] Furthermore, the limiting column 202 is controlled by a telescopic mechanism disposed in the drone body. When the battery needs to be replaced, the limiting column 202 is retracted from the limiting hole 21 of the battery, and the battery can be pulled out along the limiting strip 22. The unlocking process is relatively simple and easy to operate. When a fully charged battery is loaded, the telescopic mechanism controls the limiting column 202 to extend, thereby inserting the limiting hole 21 of the battery to fix the battery.

[0037] As an alternative solution, the limit post 202 passes through the drone body laterally, and the limit post 202 and the drone body are matched by threads. By twisting the limit post 202 located at the outer end of the drone body, the limit post 202 can be moved along its own axis, so as to be inserted or pulled out of the limit hole 21 of the battery, thereby locking or loosening the battery. In this way, the locking or loosening state can be controlled manually. When the drone has no power or no drone controller (remote control), a simple tool can be used to manually unlock or lock the battery for battery replacement.

[0038] In this embodiment, the portion of the limit post 202 that protrudes beyond the drone body is a smooth cylindrical shape, and the end has a key-shaped concave section. The smooth cylindrical shape makes the limit post 202 difficult to be twisted manually, while the key-shaped concave section requires a specially matched screwdriver to twist, which can ensure that the battery can be removed only when necessary or with special tools.

[0039] In this embodiment, the portion of the limit post 202 that exceeds the drone body is a key-shaped section 203. This solution allows the limit post 202 to be twisted to loosen or fix the battery without special tools, which is very convenient in some scenarios.

[0040] This embodiment can be found in Figure 3-8 At the side contact point between the battery and the drone, two groups of limiting holes 21 and limiting columns 202 are arranged adjacent to each other and are located at the same horizontal height, respectively located on both sides of the drone and the battery.

[0041] This drone and battery combination is suitable for the scenario of automatic battery replacement of drones. Figure 7The lower middle part is the parking platform. When the UAV is docked on the parking platform, the parking platform will locate and fix the position of the UAV to facilitate the mechanical removal or installation of the battery for battery replacement. There is a notch structure on the parking platform corresponding to the limit column 202, such as Figure 8 As shown, when the UAV stops, the limit posts 202 on both sides of the UAV enter the gap 202A of the parking platform. There is originally a kit 361 with an upper opening in the gap. The kit 361 is connected to the rotating power source through an axis rod. Both the kit 361 and the rotating power source are installed on the parking platform.

[0042] When the drone is parked on the parking platform, the limit posts 202 on both sides of the drone just enter the kit 361. When the kit 361 rotates, the limit posts 202 can be driven to rotate, so that the limit posts 202 can be inserted into the limit holes 21 of the battery or pulled out from them, thereby locking or releasing the battery. If the drone needs to be fixed on the parking platform, the original upper opening of the kit 361 is no longer facing upward when it stops rotating, that is, the limit posts 202 on both sides of the drone are covered with the kit 361, so that the drone is fixedly connected to the parking platform.

[0043] This embodiment can be found in Figure 7 and Figure 8 On the side of the drone, a protruding guide platform 204 is provided between the two limit columns 202, and the width of the guide platform 204 gradually decreases from high to low. On the parking platform, a matching structure 204A is provided, and its function is to automatically position and center the drone during the docking process by utilizing the guide platform 204 and the matching structure 204A, ensuring the accurate position after the drone stops, thereby facilitating the subsequent battery replacement process.

[0044] like Figure 6 As shown, an environment detection device 5 is mounted on the bottom of the drone. The number and model of the environment detection device 5 can be replaced and set according to the actual detection needs, so as to adapt to various different environment detection scenarios.

[0045] In summary, the utility model effectively overcomes various shortcomings in the prior art, can produce beneficial technical effects, and has significant progress.
