[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In existing technologies, drones often have short flight times due to limited battery capacity. They cannot flexibly adjust the battery capacity according to actual usage needs, requiring frequent battery replacements or charging, making it difficult to meet the needs of long-term, large-scale continuous operation.

[0019] In view of this, the present invention provides a long-endurance unmanned aerial vehicle (UAV). Through the cooperation of the UAV body, battery compartment, battery mounting slot, connecting contact point, peg lithium battery, compartment cover, limiting slot, fixing strap, anti-slip groove, slot, and fixing clip, multiple peg lithium batteries are symmetrically placed in the battery mounting slot and connected in parallel to the UAV circuitry, providing sufficient power support for the UAV. By optimizing the battery mounting structure and battery connection method, the UAV battery adopts a detachable design, allowing users to flexibly adjust the battery capacity and flight time according to actual needs by increasing or decreasing the number of peg lithium batteries installed. This avoids frequent battery replacements or charging, ensuring continuous flight of the UAV, improving operational efficiency and practicality, and enhancing the UAV's endurance and flexibility in different operating environments.

[0020] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0021] Depend on Figures 1-5 It is known that a long-endurance unmanned aerial vehicle (UAV) includes a UAV body 1. A battery compartment 2 is located on the top of the UAV body 1. Battery mounting slots 3 are equidistantly arranged inside the battery compartment 2. Connecting contact points 4 are located at the bottom of the inner wall of the battery mounting slots 3. A block lithium battery 5 is connected to the inner wall of the battery mounting slots 3. The block lithium battery 5 is composed of multiple single lithium batteries connected in series and is wrapped with an insulating layer and a protective shell to improve its safety and durability. The block lithium battery 5 is connected to the connecting contact points 4. A compartment cover 6 is connected to the top of the battery compartment 2. The bottom of the compartment cover 6 is equidistantly arranged... A limiting groove 7 is provided, which is connected to the block lithium battery 5. The bottom sides of the cover 6 are both embedded with fixing straps 8 at equal intervals. The outer wall of the fixing strap 8 is provided with anti-slip grooves 9 at equal intervals. The anti-slip grooves 9 are used to increase the friction of the fixing strap 8, so that the fixing strap 8 is more firmly locked between the slot 10 and the fixing clip 11, and it is not easy to slip off. The outer walls of the battery compartment 2 are both provided with slots 10 at equal intervals. The fixing strap 8 is connected to the slot 10. The battery compartment 2 is located inside the slot 10 and the fixing clip 11 is provided. The fixing strap 8 and the anti-slip groove 9 are both connected to the fixing clip 11.

[0022] In the specific implementation process, it is worth noting that the drone body 1, which is the airframe structure of the drone, adopts a coaxial dual-propeller quadcopter design, giving the drone high stability and controllability, reducing the overall size of the drone, and giving the drone greater lift. The block lithium battery 5 is composed of multiple single lithium batteries connected in series, and is wrapped with an insulating layer and protective shell to improve its safety and durability. Through the cooperation between the drone body 1, battery compartment 2, battery mounting slots 3, connecting contact points 4, and block lithium batteries 5, the battery compartment 2 is located on the top of the drone body 1. It has multiple battery mounting slots 3 inside, and connecting contact points 4 are installed inside each battery mounting slot 3. The connecting contact points 4 are connected to the power supply circuit of the drone. Place the block lithium battery 5 into the battery mounting slot 3, ensuring the electrodes of the block lithium battery 5 contact the connection point 4. The block lithium battery 5 can then be connected to the drone's circuitry. When multiple block lithium batteries 5 are installed, they are connected in parallel to the drone's circuitry, providing power to the drone. The battery capacity and flight time of the drone can be adjusted by increasing or decreasing the number of block lithium batteries 5 as needed. Through the cooperation of the battery compartment 2, battery mounting slot 3, block lithium battery 5, compartment cover 6, and limiting slot 7, after the block lithium battery 5 is placed in the battery mounting slot 3, covering the top of the battery compartment 2 with the compartment cover 6 inserts the top of the block lithium battery 5 into the limiting slot 7, thus limiting the block lithium battery 5 and preventing it from... In case of loosening or detachment during drone flight, the battery compartment 2, cover 6, fixing strap 8, anti-slip groove 9, slot 10, and fixing clip 11 work together. The fixing strap 8 at the bottom of the cover 6 is inserted into the slot 10 and secured by the fixing clip 11, thus securing the cover 6 to the battery compartment 2. This prevents the cover 6 from loosening or detaching during flight and maintains tight contact with the top of the block lithium battery 5, further ensuring the stability and safety of the drone's power supply. The anti-slip groove 9 increases the friction of the fixing strap 8, making it more securely engaged between the slot 10 and the fixing clip 11, preventing slippage. The components include the drone body 1, battery compartment 2, battery mounting slot 3, connecting contact point 4, block lithium battery 5, cover 6, and limiting groove. 7. The cooperation between the fixing strap 8, anti-slip groove 9, slot 10, and fixing clip 11 allows multiple cubic lithium batteries 5 to be symmetrically placed in the battery mounting slot 3, connecting them in parallel to the drone's circuitry. This provides ample power support for the drone. Optimizing the drone's battery mounting structure and connection method allows for a detachable battery design, enabling users to flexibly adjust the battery capacity and flight time by increasing or decreasing the number of cubic lithium batteries 5 according to actual needs. This avoids frequent battery replacements or charging, ensuring continuous drone flight, improving operational efficiency and practicality, and enhancing the drone's endurance and flexibility in different operating environments.The specific models of contact point 4 and the square lithium battery 5 are not limited, as long as they meet the usage requirements;

[0023] Furthermore, a rubber pad 12 is provided on the top of the inner wall of the limiting groove 7. The rubber pad 12 is connected to the block lithium battery 5. A thin film pressure sensor 13 is embedded in the top of the rubber pad 12. A display screen 14 is provided on the top of the compartment cover 6. Battery status indicator lights 15 are equidistantly arranged on one side of the display screen 14 on the compartment cover 6. Solar panels 16 are provided on both sides of the top of the compartment cover 6. An energy storage module 17 is provided inside the compartment cover 6. A controller 18 is provided inside the compartment cover 6 on one side of the energy storage module 17. The thin film pressure sensor 13, the display screen 14, the battery status indicator lights 15, the solar panels 16 and the energy storage module 17 are all electrically connected to the controller 18.

[0024] In the specific implementation process, it is worth noting that through the cooperation between the battery compartment 2, battery mounting slot 3, connecting contact point 4, block lithium battery 5, compartment cover 6, limiting groove 7, and rubber pad 12, after the compartment cover 6 is fixed to the battery compartment 2, the rubber pad 12 in the limiting groove 7 abuts against the top of the block lithium battery 5, improving the stability of the block lithium battery 5, thereby ensuring close contact between the electrodes of the block lithium battery 5 and the connecting contact point 4, ensuring stable power supply to the drone. Through the cooperation between the compartment cover 6, solar panel 16, energy storage module 17, and controller 18, a simple solar charging system is formed inside the compartment cover 6. The solar panel 16 can convert light energy into electrical energy, which is stored through the energy storage module 17 to power the controller 18 and other electrical components inside the compartment cover 6. Through the cooperation between the compartment cover 6, limiting groove 7, rubber pad 12, thin film pressure sensor 13, and display... The cooperation between the display screen 14, battery status indicator 15, solar panel 16, energy storage module 17, and controller 18 is as follows: after the rubber pad 12 and the block lithium battery 5 are pressed together, the thin-film pressure sensor 13 can detect the pressing force between the rubber pad 12 and the block lithium battery 5 and transmit the signal to the controller 18. The controller 18 controls the battery status indicator 15 at the corresponding position according to the received signal to display the installation status of the block lithium battery 5. Based on the capacity and number of block lithium batteries 5 installed, the display screen 14 displays the total capacity of the drone battery and the estimated flight time, so that users can quickly understand the number of block lithium batteries 5 installed and the flight time. The specific models of the thin-film pressure sensor 13, display screen 14, battery status indicator 15, solar panel 16, energy storage module 17, and controller 18 are not limited, as long as they meet the usage requirements.

[0025] Furthermore, the top of the battery compartment 2 is provided with a sealing protrusion 19, and the bottom of the compartment cover 6 is provided with a sealing groove 20. A sealing gasket 21 is provided inside the sealing groove 20, and both the sealing groove 20 and the sealing gasket 21 are connected to the sealing protrusion 19.

[0026] In the specific implementation process, it is worth noting that through the cooperation between the battery compartment 2, the cover 6, the sealing protrusion 19, the sealing groove 20 and the sealing gasket 21, after the cover 6 is snapped into the top of the battery compartment 2, the sealing protrusion 19 is inserted into the interior of the sealing groove 20 and abuts against the sealing gasket 21, so that the connection between the battery compartment 2 and the cover 6 forms a sealed structure, which effectively prevents external impurities such as dust and moisture from entering the interior of the battery compartment 2 and damaging the drone circuit and the square lithium battery 5, thereby improving the service life and safety of the drone.

[0027] Furthermore, heat dissipation grooves 22 are equidistantly arranged on the outer wall of the battery compartment 2. The heat dissipation grooves 22 are used to improve the heat dissipation performance of the battery compartment 2, so that the heat generated by the block lithium battery 5 can be dissipated in time, avoiding the internal temperature of the battery compartment 2 from being too high, affecting the performance and safety of the block lithium battery 5, and further extending the flight time of the drone.

[0028] In the specific implementation process, it is worth noting that the heat dissipation slot 22 is used to improve the heat dissipation performance of the battery compartment 2, so that the heat generated by the block lithium battery 5 can be dissipated in time, avoiding the internal temperature of the battery compartment 2 from being too high, affecting the performance and safety of the block lithium battery 5, and further extending the flight time of the drone.

[0029] Furthermore, the battery compartment 2 is provided with arc-shaped grooves 23 on both sides of the battery mounting groove 3, and air guide grooves 24 are provided at equal intervals on both sides of the inner wall of the battery mounting groove 3.

[0030] In the specific implementation process, it is worth noting that through the cooperation between the battery compartment 2, the battery mounting slot 3, the arc-shaped slot 23, and the air guide slot 24, when the block lithium battery 5 is pulled out of the battery mounting slot 3, the arc-shaped slot 23 makes it easier for the user's fingers to grip and hold the block lithium battery 5 over a larger area, and the air guide slot 24 allows air to smoothly enter the interior of the battery mounting slot 3, so that the air pressure inside the battery mounting slot 3 can be balanced with the outside air, reducing the resistance when installing or removing the block lithium battery 5, making it easier for the user to quickly and effortlessly complete the installation or removal of the block lithium battery 5, and improving the user experience.
