[0002] An unmanned aerial vehicle, abbreviated as "drone", is an unpiloted aircraft controlled by radio remote control equipment and a self - contained program control device. Due to its characteristics such as being flexible, having a fast response speed, not requiring manual driving, having low operation requirements, and being able to carry a variety of small devices or objects, it has been widely used. Currently, the application scope of drones has expanded to many fields such as civilian, scientific research, and even military and national defense. In particular, it is widely used in aspects such as power, communication, meteorology, agriculture, ocean, exploration, photography, disaster prevention and mitigation, drug suppression and smuggling, border patrol, and public security anti - terrorism. Most small drones use batteries as the power source, and the stability and reliability of battery installation play a crucial role in the use of drones.

[0003] Therefore, to ensure flight safety, before the drone takes off, the operator needs to manually check whether the battery is in the locked state. This process increases the workload of the operator, prolongs the preparation time before the drone takes off, and is prone to safety hazards during the flight of the drone due to mistakes in manual inspection.

[0006] On the one hand, an embodiment of this application provides a battery locking structure, including a locking base, a locking part, and a micro - switch. The locking part is movably arranged on the locking base. The locking part has a first position for clamping with the battery and a second position for releasing the clamping with the battery. When the locking part switches from the first position to the second position, the locking part triggers the micro - switch so that the micro - switch outputs a no - fly signal indicating that the locking part is in the second position.

[0007] Optionally, the locking part has a limit groove, and the locking base has a limit protrusion. When the locking part is in the first position, the limit protrusion cooperates with the limit groove for clamping. When the locking part is in the second position, the limit protrusion is disengaged from the limit groove.

[0008] Optionally, the limit protrusion at least includes a first vertical surface and a first inclined surface, and the limit groove is adapted to the shape of the limit protrusion.

[0009] Optionally, the lock base includes a base and a support base slidably disposed on the base, the limit protrusion is located on the support base, and the support base is also provided with a trigger member. When the lock member switches from the first position to the second position, the lock member is driven to push the support base to slide so that the limit protrusion and the limit groove are released from the clamping connection, and the trigger member moves toward the direction close to the micro switch to trigger the micro switch.

[0010] Optionally, the battery lock structure further includes an elastic member connected to the support base, and the elastic member is used to provide a reset force to the support base so that the limiting protrusion has a tendency to cooperate and engage with the limiting groove.

[0017] The present application provides a battery locking structure and a drone, including a locking base, a locking member, and a microswitch. The locking member is movably arranged on the locking base. The locking member has a first position for clamping with the battery and a second position for releasing the clamping with the battery. When the locking member switches from the first position to the second position, the locking member triggers the microswitch so that the microswitch outputs a no-fly signal indicating that the locking member is in the second position.

Detailed implementation manners

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Generally, the components of the embodiments of the present application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application claimed, but merely represents selected embodiments of the present application. It should be noted that, without conflict, the various features in the embodiments of the present application can be combined with each other, and the combined embodiments are still within the protection scope of the present application.

[0029] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0030] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this application is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0031] In addition, terms such as "horizontal" and "vertical" do not require the components to be absolutely horizontal or hanging vertically, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0032] In the description of the present application, it should also be noted that, unless otherwise clearly specified and limited, the terms "arranged", "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0033] On the one hand of the embodiments of the present application, a battery latch structure 10 is provided, as Figures 1 to 7 shown, which includes a latch base 100, a latch member 200, and a micro switch 300. The latch member 200 is movably arranged on the latch base 100. The latch member 200 has a first position for clamping with the battery and a second position for releasing the clamping with the battery. When the latch member 200 switches from the first position to the second position, the latch member 200 triggers the micro switch 300 so that the micro switch 300 outputs a no-fly signal for indicating that the latch member 200 is in the second position.

[0034] By movably arranging the latch member 200 on the latch base 100, the latch member 200 can be driven to switch between the first position and the second position. The first position is the position where the latch member 200 clamps with the battery, and at this time the battery is firmly fixed in the drone; the second position is the position where the latch member 200 releases the clamping with the battery, and in this position the battery can be easily taken out or replaced. When the latch member 200 switches from the first position to the second position, it will trigger the micro switch 300, so that when the latch member 200 reaches the second position, the micro switch 300 is triggered and outputs a no-fly signal for indicating that the battery is in the unlocked state. That is, as long as the latch member 200 is not in the first position, the micro switch 300 will be triggered to output the no-fly signal. This design not only realizes the movable connection between the latch member 200 and the latch base 100 in terms of structure, but also forms an intelligent monitoring system by introducing the micro switch 300. The no-fly signal output by the micro switch 300 is directly connected to the control system of the drone. When the drone receives this no-fly signal, the control system will automatically prohibit the take-off operation. Such a design effectively prevents flight accidents that may be caused by the battery not being correctly locked and improves the safety performance of the drone.

[0035] Generally speaking, the cooperation between the locking part 200 and the micro switch 300 enables the battery locking structure 10 to not only have a mechanical locking function but also an electrical feedback function. The physical movement of the locking part 200 when switching positions triggers the micro switch 300, and the signal output by the micro switch 300 is transmitted to the control system of the drone, enabling the control system to monitor the locking state of the battery in real time and prohibit the takeoff operation when the battery is not correctly locked. This design that combines electricity and mechanics enhances the intelligent level of the system, ensures that the drone can only take off when the battery is correctly locked, guarantees the flight safety of the drone, improves the operation efficiency, and reduces potential safety hazards.

[0036] Optionally, the locking part 200 has a limiting groove 210, and the locking base 100 has a limiting protrusion 121. When the locking part 200 is in the first position, the limiting protrusion 121 is engaged with the limiting groove 210 in a snap-fit manner. When the locking part 200 is in the second position, the limiting protrusion 121 is disengaged from the limiting groove 210.

[0037] As Figure 1 shown, the locking part 200 is designed with a limiting groove 210, while the locking base 100 is provided with a limiting protrusion 121. When the locking part 200 is in the first position, the limiting protrusion 121 is tightly engaged with the limiting groove 210, which ensures the stability of the locking part 200 in the first position, thereby firmly locking the battery in the drone. Such a design provides a physical locking mechanism to prevent the battery from loosening or falling off during flight.

[0038] When the battery needs to be replaced, the locking part 200 switches from the first position to the second position. During this process, the limiting protrusion 121 is disengaged from the limiting groove 210, enabling the locking part 200 to move smoothly, so that the battery can be taken out or replaced. This design not only simplifies the installation and disassembly process of the battery but also ensures the convenience and reliability of the operation.

[0039] In addition, the key point of this design is that the locking part 200 can be driven to flexibly switch between the first position and the second position, providing convenience for the loading and unloading of the battery. At the same time, through the reasonable setting of the limiting structure, the firmness and reliability of the battery locking structure 10 are maintained during the switching process of the locking part 200 between the two positions. This innovative battery locking structure 10 not only improves the convenience and safety of battery loading and unloading but also provides more stable and reliable power support for the use of the drone.

[0040] More importantly, when the locking member 200 is switched to the second position, the micro switch 300 is triggered. When triggered, the micro switch 300 outputs a no-fly signal, which is transmitted to the control system of the drone. After receiving this no-fly signal, the drone automatically prohibits the takeoff operation. This intelligent design solves the drawbacks of traditional manual inspection, ensures that the battery is in the correct locked state before each takeoff, and improves the safety of the drone.

[0041] Optionally, the limiting protrusion 121 at least includes a first vertical surface and a first inclined surface, and the limiting groove 210 is adapted to the shape of the limiting protrusion 121.

[0042] Specifically, as Figure 1 shown, in the design of the battery locking structure 10, the shape design of the limiting protrusion 121 plays a key role. The limiting protrusion 121 at least includes a first vertical surface and a first inclined surface. This design enables the locking member 200 to rotate only in one direction, such as counterclockwise or clockwise, so as to achieve position switching. This design effectively prevents the locking member 200 from rotating repeatedly in two directions, thus avoiding safety problems caused by loosening or misalignment. Specifically, the limiting groove 210 is adapted to the shape of the limiting protrusion 121, that is, the limiting groove 210 at least includes a second vertical surface that cooperates with the first vertical surface and a second inclined surface that cooperates with the first inclined surface, ensuring that when the locking member 200 is in the first position, the limiting protrusion 121 can be firmly clamped with the limiting groove 210. When the locking member 200 rotates to the second position, the limiting protrusion 121 is disengaged from the limiting groove 210, allowing the battery to be removed or replaced. Through this adaptation design, it is ensured that each rotation of the locking member 200 can accurately and reliably achieve the functions of locking and unlocking.

[0043] It should be understood that, as Figures 2 to 7 shown, during the process of the locking member 200 being driven to switch from the first position to the second position, when the locking member 200 rotates, the second inclined surface is first misaligned with the limiting protrusion 121, and then during the continuous rotation of the locking member 200, the second vertical surface is also misaligned with the limiting protrusion 121. At this time, the locking member 200 is switched to the second position; during the process of the locking member 200 being driven to switch from the second position to the first position, when the locking member 200 rotates, the second vertical surface first contacts the limiting protrusion 121, and then during the continuous rotation of the locking member 200, the second inclined surface also contacts the limiting protrusion 121. At this time, the locking member 200 is switched to the first position.

[0044] To further improve the stability and anti-detachment performance of the buckle structure, straight teeth can be provided on the first vertical surface of the limiting protrusion 121, and helical teeth can be provided on the first inclined surface. The design of the straight teeth and helical teeth increases the firmness of the clamping connection, ensuring that the buckle 200 will not become loose due to vibration or impact in the locked state. At the same time, the design of the helical teeth enables the buckle 200 to have a smooth transition during rotation, reducing wear and friction, and improving the operating smoothness and durability of the buckle 200.

[0045] Optionally, the buckle base 100 includes a base body 110 and a support seat 120 slidably disposed on the base body 110. The limiting protrusion 121 is located on the support seat 120, and the support seat 120 is further provided with a trigger member 122. When the buckle 200 is switched from the first position to the second position, the buckle 200 is driven to push the support seat 120 to slide so that the limiting protrusion 121 is disengaged from the limiting groove 210, and the trigger member 122 moves in a direction close to the micro switch 300 to trigger the micro switch 300.

[0046] Specifically, as Figures 2 to 7 shown, the buckle base 100 is composed of a base body 110 and a support seat 120 slidably disposed on the base body 110. The limiting protrusion 121 is located on the support seat 120, and at the same time, the support seat 120 is further provided with a trigger member 122. The purpose of this design is that when the buckle 200 is switched from the first position to the second position, the buckle 200 is driven by a driving force to push the support seat 120 to slide, so that the limiting protrusion 121 is disengaged from the limiting groove 210. At the same time, the trigger member 122 on the support seat 120 moves in the direction of the micro switch 300 to trigger the micro switch 300 and output a no-fly signal. In the embodiment of the present application, the trigger member 122 is a trigger rod, and the specific operation process is as follows:

[0047] When the buckle 200 is clamped with the battery, that is, in the first position, the first vertical surface and the first inclined surface of the limiting protrusion 121 are respectively in close fit with the second vertical surface and the second inclined surface of the limiting groove 210, ensuring that the battery is firmly locked in the drone. If the battery needs to be removed, only a driving force needs to be applied to the buckle 200. This driving force is transmitted to the first inclined surface through the second inclined surface, generating an interference extrusion force, pushing the support seat 120 to slide, and disengaging the limiting protrusion 121 from the limiting groove 210. As the support seat 120 slides, the trigger member 122 also moves, triggering the micro switch 300 and outputting a no-fly signal, indicating that the battery has been unlocked.

[0048] When the battery is disengaged and in the second position, if it is necessary to reinstall the battery firmly in the drone, a driving force in the same direction can be continuously applied to rotate the locking member 200 in the same direction. As the locking member 200 rotates, the limiting protrusion 121 cooperates with the second inclined surface and the first inclined surface of the limiting groove 210 again until the first vertical surface of the limiting protrusion 121 cooperates and engages with the second vertical surface of the limiting groove 210 to ensure that the battery is firmly locked. At this time, the triggering member 122 leaves the microswitch 300, and the microswitch 300 returns to its initial state. The control system detects that the locking member 200 is in the first position and allows the drone to take off normally.

[0049] It should be noted that there can be one limiting groove 210. Correspondingly, there is also one limiting protrusion 121. At this time, when the locking member 200 is driven to switch from the first position to the second position and then from the second position to the first position, it needs to rotate 360°. There can also be multiple limiting grooves 210. As Figure 1 shown, there can be two limiting grooves 210, and the two limiting grooves 210 are arranged centrosymmetrically along their connection line. Correspondingly, there are also two limiting protrusions 121, and the two limiting protrusions 121 are arranged centrosymmetrically along their connection line. At this time, when the locking member 200 is driven to switch from the first position to the second position and then from the second position to the first position, it only needs to rotate 180°. The arrangement of the two limiting grooves 210 and the two limiting protrusions 121 makes the rotation process of the locking member 200 more balanced, makes the engagement between the locking member 200 and the locking base 100 more stable, shortens the single rotation path, and extends the service life of the battery locking structure 10.

[0050] It should also be noted that as Figure 2 shown, when the limiting protrusion 121 engages with the limiting groove 210, that is, when the locking member 200 is in the first position, the length direction of the locking member 200 can be perpendicular to the length direction of the locking base 100, and both ends of the locking member 200 extend out of the locking base 100 along the length direction so that the locking member 200 can engage with the battery; as Figure 4 and Figure 6 shown, when the locking member 200 is driven by an external force to disengage the limiting protrusion 121 from the limiting groove 210, that is, when the locking member 200 is in the second position, the length direction of the locking member 200 can be parallel to the length direction of the locking base 100, or the length direction of the locking member 200 can form an angle other than 90° with the length direction of the locking base 100 so that the locking member 200 can disengage from the battery.

[0051] Optionally, when the locking member 200 is in the first position, the locking member 200 has a clamping portion 220 protruding from the locking base 100, and the locking member 200 clamps the battery through the clamping portion 220.

[0052] As shown Figure 1 in the figure, the locking fastener 200 has a clamping portion 220. When the locking fastener 200 is in the first position, the clamping portion 220 protrudes from the locking base 100. The function of the clamping portion 220 is to form a stable connection with the battery, ensuring that when the locking fastener 200 is in the first position, the battery can be safely and reliably clamped on the locking base 100.

[0053] The design of the clamping portion 220 takes into account multiple factors, such as the selection of materials and the optimization of shapes. This enables the clamping portion 220 to provide sufficient friction and tightness when clamping with the battery, so that the battery is not easily affected by external vibrations or impacts during flight, ensuring that the battery does not accidentally fall off during use.

[0054] Therefore, through the clamping portion 220 of the locking fastener 200 when in the first position, this battery locking structure 10 fully reflects the comprehensive consideration of safety, stability, and user experience. This innovative design has significantly improved the functionality and practicality of the battery locking structure 10, enabling this battery locking structure 10 to be widely used in various battery-driven devices.

[0055] Optionally, the battery locking structure 10 further includes an elastic member 400 connected to the support seat 120. The elastic member 400 is used to provide a restoring force to the support seat 120, so that the limiting protrusion 121 has a tendency to cooperate and engage with the limiting groove 210.

[0056] As shown Figure 1 in the figure, in the battery locking structure 10, in addition to the ingenious design of the locking fastener 200 and the locking base 100, an elastic member 400 connected to the support seat 120 is added. By applying a pre-tightening force to the elastic member 400, the locking fastener 200 can stably stop in the first position or the second position when not subjected to external forces. This design further improves the performance and reliability of the battery locking structure 10. At the same time, the elastic member 400 can also provide a restoring force to the support seat 120, thus ensuring that the limiting protrusion 121 has a tendency to cooperate and engage with the limiting groove 210.

[0057] When the locking member 200 is driven to move from the first position to the second position or from the second position to the first position, the support seat 120 is pushed to slide. The sliding of the support seat 120 also drives the deformation of the elastic member 400, storing the force in the form of deformation. This energy storage mechanism allows the battery locking structure 10 to be smoother and more efficient when engaging or disengaging with the battery. When the locking member 200 moves to the second position or the first position, the driving force on the locking member 200 is removed. At this time, the elastic member 400 releases the stored energy and provides a reset force to the support seat 120. This reset force makes the limiting protrusion 121 have a tendency to engage with the limiting groove 210, ensuring that the locking member 200 can switch between the two positions quickly and stably.

[0058] In general, the design of the elastic member 400 significantly improves the reliability and stability of the battery lock structure 10. The elastic member 400 not only reduces the impact force when the support base 120 slides, but also provides a reset force to make the clamping between the limiting protrusion 121 and the limiting groove 210 more secure. This design makes the battery lock structure 10 more intelligent and efficient in practical applications, while ensuring the reliability of the battery lock structure 10 in various environments and extending the service life of the battery lock structure 10.

[0059] Optionally, the battery lock structure 10 further includes a mounting shaft 500 fixed to the lock base 100, an annular protrusion 510 is provided on the mounting shaft 500, a through-going variable diameter mounting hole 230 is provided in the lock member 200, the side wall surface of the variable diameter mounting hole 230 is a stepped surface, the mounting shaft 500 is rotatably arranged in the variable diameter mounting hole 230, and the annular protrusion 510 abuts against the stepped surface.

[0060] Specifically, if Figure 1 As shown, the mounting shaft 500 is rotated and penetrated in the variable diameter mounting hole 230, and the variable diameter mounting hole 230 gradually decreases along the penetration direction of the mounting shaft 500, so that the mounting shaft 500 is stably penetrated in the variable diameter mounting hole 230, and the annular protrusion 510 can cleverly cooperate with the stepped surface to form a tight connection mechanism. This design ensures the stability of the locking member 200 on the mounting shaft 500, and also prevents the locking member 200 from unnecessary shaking or movement along the axis direction of the mounting shaft 500 during rotation. The reasonable design of this structure not only ensures the firmness of the battery lock, but also increases the durability and vibration resistance of the entire lock structure.

[0061] Optionally, such as Figure 1 As shown in FIG. 1 , a fastener 600 is provided at one end of the lock base 100 away from the lock member 200, and the mounting shaft 500 is fixedly connected to the fastener 600 to ensure that the connection between the lock base 100 and the fastener 600 is unbreakable in an environment of high-speed movement and vibration. ​​

[0062] It should be noted that the mounting shaft 500 can be a high-strength support shaft such as a shoulder screw, a shoulder pin, a pin shaft, etc. Different structures and functions can be selected according to the requirements of specific scenarios to meet various connection and fixing needs. The flexibility of this design provides strong support for the wide application of the battery buckle in different application fields; the fastener 600 can be an insert nut, and the knurling or other patterns of the insert nut are buried in the reserved installation space of the buckle base 100. The fastener 600 can also be a hot-melt nut, which is fixedly installed in the reserved installation space of the buckle base 100 by hot-melting or injection molding, and the mounting shaft 500 is fixedly passed through the fastener 600 to achieve a threaded connection. Thus, the mounting shaft 500, the fastener 600 and the buckle base 100 are reliably connected as a whole.

[0063] Optionally, the battery buckle structure 10 further includes an anti-wear member 700, and the annular protrusion 510 abuts against the stepped surface through the anti-wear member 700.

[0064] As Figure 1 shown, in the further design of the battery buckle structure 10, an anti-wear member 700 is introduced. The purpose of this design is to improve the wear resistance and stability of the buckle structure. Generally, the buckle 200 is made of plastic material, while the mounting shaft 500 is made of metal material. In order to maximize the role of the anti-wear member 700, the material of the anti-wear member 700 should be matched with the two respectively. Such a design ensures that the anti-wear member 700 is coordinated with the materials of the buckle 200 and the mounting shaft 500, forming a closer connection, so that the entire buckle structure can maintain good performance during high-speed movement and frequent use.

[0065] Specifically, through the setting of the anti-wear member 700, the annular protrusion 510 forms an effective wear-resistant connection with the stepped surface. In the embodiment of the present application, the anti-wear member 700 mainly includes two parts, a copper gasket 710 and a plastic gasket 720, which play a role in reducing wear and increasing the service life in the buckle structure. The layered structure between the copper gasket 710 and the plastic gasket 720 not only reduces the friction between the metal and the plastic, but also effectively slows down the wear rate of the buckle 200 during movement. By reducing friction, the stability and durability of the battery buckle structure 10 are significantly improved. The copper gasket 710, as a part of the anti-wear member 700, is arranged between the annular protrusion 510 and the plastic gasket 720. This configuration not only provides additional strength and stability, but also forms a buffer layer between the metal and the plastic, reducing the friction of the buckle during movement. The plastic gasket 720 is responsible for further reducing wear. It contacts the stepped surface, making the movement of the buckle 200 smoother.

[0066] On the other hand, an embodiment of the present application provides a drone, as Figures 2 to 7As shown in the figure, it includes a drone body and a battery locking structure 10 as described in any of the above. A battery compartment 20 for installing a battery is provided on the drone body. In order to improve the safety and stability of the battery, the locking base 100 of the battery locking structure 10 is ingeniously arranged in the battery compartment 20. The locking part 200 of the battery locking structure 10 is clamped with the battery in the battery compartment 20 at the first position and released from clamping with the battery in the battery compartment 20 at the second position. When the locking part 200 is in the first position, it is clamped with the battery in the battery compartment 20, forming a firm connection. In this process, the setting of the locking base 100 ensures the stability of the locking part 200, and the battery can be safely and reliably installed on the drone body. When the drone needs to replace the battery or perform maintenance, the locking part 200 can be switched to the second position to release the clamping with the battery, easily realizing the quick replacement or release of the battery. Since the drone includes the above-mentioned battery locking structure 10, it also has the same beneficial effects as the battery locking structure 10, which will not be elaborated here.

[0067] Optionally, the drone further includes a control system. The microswitch 300 of the battery locking structure 10 is electrically connected to the control system, and the control system is used to control the flight state of the drone according to the no-fly signal of the microswitch 300.

[0068] Specifically, the microswitch 300, the locking part 200 and the locking base 100 are integrated in the battery compartment 20, and the microswitch 300 is electrically connected to the control system, so that the no-fly signal output by the microswitch 300 can be sent to the control system of the drone. Thus, when the locking part 200 is in the first position, the control system does not receive the no-fly signal, and the control system controls the drone to take off normally. When the locking part 200 is in the second position, the control system will receive this no-fly signal, and the control system will automatically prohibit the take-off operation. Such a design effectively prevents flight accidents that may be caused by incorrect battery locking and improves the safety performance of the drone.

[0069] Optionally, the locking base 100 is detachably connected to the battery compartment 20, or the locking base 100 is non-detachably connected to the battery compartment 20.

[0070] In this innovative technical solution, the connection method between the locking base 100 and the battery compartment 20 demonstrates flexibility and diversity. This design allows the locking base 100 and the battery compartment 20 to either be detachably connected or non-detachably connected to meet the requirements of different application scenarios.

[0071] First, for the detachable connection method, bolt connection is a common and effective option. By designing the bolt connection, the connection between the latch base 100 and the battery compartment 20 becomes detachable, enabling users to disassemble the battery latch structure 10 more conveniently. Moreover, the bolt connection can increase the connection points between the battery latch structure 10 and the battery compartment 20, which is beneficial for sharing the force and reducing the concentrated stress. In addition, other detachable connection methods include quick-release pins, pin connections, etc., which all provide convenient solutions for the connection between the battery latch structure 10 and the battery compartment 20.

[0072] On the contrary, the non-detachable connection design adopts methods such as integral molding. Integral molding makes the latch base 100 and the battery compartment 20 form an integral body through process techniques and cannot be easily disassembled. This connection method is suitable for scenarios with higher structural requirements. The integral molding design increases the overall strength of the latch structure, ensuring that there are no safety hazards due to the loosening of the connection components during flight.

[0073] Generally speaking, this UAV design demonstrates diversity and customizability in the connection method of the battery latch structure 10. Whether it is a detachable connection or a non-detachable connection, it provides users with more choices, enabling the UAV to better meet the requirements of various actual application scenarios.

[0074] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
