[0038] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0039] This application provides a drone battery assembly that can solve the problem of drone batteries being difficult to disassemble.

[0040] Referring to Figures 1 and 2, the drone battery assembly 00 includes a housing 10, a panel 20, a charging interface 30, a power supply interface 40, and a pair of snap-fit ​​structures 50. The drone battery is located inside the housing 10, and the panel 20 is located at the first end of the housing 10 and is connected to the drone battery. The charging interface 30 is located on the panel 20, and the charging interface 30 can be located on the side of the panel 20 opposite to the housing 10. The charging interface 30 is adapted to be connected to a charging socket. Referring to Figure 10, when the charging socket is a charging plug 302, the charging interface 30 can be connected to the charging plug 302 to charge the drone battery.

[0041] As shown in Figure 2, the charging interface 30 may include a recessed area 31 and multiple interface contacts 32, which are located within the recessed area 31. Referring to Figure 10, the charging plug 302 has multiple plug contacts 303 corresponding to the multiple interface contacts 32. When the drone 01 needs to be charged, the recessed area 31 of the charging interface 30 can be coupled to the charging plug 302, and the multiple interface contacts 32 of the charging interface 30 and the multiple plug contacts 303 of the charging plug 302 are electrically connected in a one-to-one correspondence. Simultaneously, the charging plug 302 is connected to a power source, thereby charging the drone 01.

[0042] Referring again to Figure 2, the charging interface 30 may also include two magnetic parts 33. The two magnetic parts 33 may be rectangular and are located on both sides of the multiple interface contacts 32. The charging plug 302 has two corresponding magnetic parts. When the charging interface 30 and the charging plug 302 are coupled, the two magnetic parts 33 can attract each other with the two magnetic parts of the charging plug 302, so that the charging interface 30 and the charging plug 302 are connected more tightly. This allows the interface contacts 32 and the plug contacts 303 to make better and more stable contact, reducing the problem of poor contact during charging.

[0043] As shown in Figure 1, the power supply interface 40 can be located on the housing 10, away from the panel 20. The power supply interface 40 has multiple sockets 41. Referring to Figure 6, the drone 01 has a power interface 06 corresponding to the power supply interface 40, and the power interface 06 has multiple prongs 061. When the drone 01 needs power, the power interface 06 connects to the power supply interface 40, and the multiple prongs 061 of the power interface 06 are inserted one-to-one into the multiple sockets 41 of the power supply interface 40, thereby supplying power to the drone 01.

[0044] Referring to Figure 1, the housing 10 may also have a pair of snap-fit ​​structures 50, located on both sides of the housing 10. Referring to Figure 6, the side wall of the battery compartment 03 of the drone 01 has corresponding grooves 04. When the housing 10 is pushed into the battery compartment 03, the two snap-fit ​​structures 50 are compressed and deformed. As the housing 10 continues to be pushed, the two snap-fit ​​structures 50, under their own stress, can extend into the grooves 04 and lock together, thus connecting and fixing the drone battery to the battery compartment 03. When the battery needs to be removed, press the snap-fit ​​structures 50 to separate them from the grooves 04, and simultaneously pull the housing 10 out of the battery compartment 03.

[0045] In summary, the drone battery assembly provided in this application includes a housing, a panel, a charging interface, a power supply interface, and a pair of snap-fit ​​structures. The drone battery is located inside the housing, and the two snap-fit ​​structures are located on both sides of the housing. The drone's battery compartment has grooves at corresponding positions that mate with the snap-fit ​​structures. When installing the battery onto the drone, the housing of the drone battery assembly needs to be pushed into the drone's battery compartment. The two snap-fit ​​structures of the housing are squeezed by the side walls of the battery compartment and deform towards the housing. Continuing to push the housing further in, the two snap-fit ​​structures, under their own stress, can extend into the grooves of the battery compartment. The snap-fit ​​structures and grooves engage and lock together, thus connecting and fixing the drone battery to the battery compartment. This allows the drone to be stored in a drone hangar for charging when not in use. When the battery needs to be removed, the snap-fit ​​structures are pressed to separate from the grooves, and the housing is pulled out of the battery compartment, allowing the battery to be detached and connected to a portable charging plug for individual charging. This snap-fit ​​structure makes the installation and removal of the drone battery convenient, adaptable to various charging environments, and improves the user experience.

[0046] As shown in Figure 2, the panel 20 of the drone battery assembly 00 may further include a pair of recessed structures 21. The two recessed structures 21 are located at opposite positions on both sides of the panel 20. Optionally, the two recessed structures 21 may be located at two adjacent rounded corners of the panel 20. Correspondingly, the drone body also has two recessed structures at corresponding positions on both sides. Referring to Figure 5, the sides of the two recessed structures on the drone body 02 can be connected to the sides of the two recessed structures 21 of the drone battery assembly 00, so that these two recessed structures can be combined with the two recessed structures 21 of the drone battery assembly 00 to form two new recessed structures 22, which can play a guiding and limiting role when the drone battery assembly 00 is inserted into the drone body 02. At the same time, the two new recessed structures 22 can be coupled to two fastening structures that are adapted to their shapes, thereby further ensuring the stable connection between the drone battery assembly 00 and the drone body 02.

[0047] As shown in Figure 1, it should be noted that the snap-fit ​​structure 50 is disconnected from the housing 10, and the end of the snap-fit ​​structure 50 away from the housing 10 can be connected to the panel 20. This gives the snap-fit ​​structure 50 a certain degree of elasticity, allowing it to deform towards the housing 10 when subjected to external pressure or compression. Furthermore, the snap-fit ​​structure 50 can be manufactured using an integral molding process with the panel 20, resulting in a simpler structure and manufacturing process, thus reducing production costs.

[0048] Referring to Figure 3, the snap-fit ​​structure 50 includes an actuating part 51, a connecting part 52, and a hook part 53. The connecting part 52 is used to connect the actuating part 51 and the hook part 53 together. The actuating part 51 protrudes outward relative to the hook part 53. The actuating part 51 is closer to the first end of the housing 10 than the hook part 53. The panel 20 is located at the first end of the housing 10, that is, the actuating part 51 is closer to the panel 20 than the hook part 53.

[0049] In the buckle structure 50, the actuating part 51 can be connected to the panel 20, while the connecting part 52 and the hook part 53 in the buckle structure 50 are disconnected from the panel 20 and from the housing 10, so that the buckle structure 50 has a certain degree of elasticity.

[0050] The end of the actuator 51 away from the hook 53 can be connected to the panel 20. The actuator 51 can be parallel to the side wall of the panel 20, and the actuator 51 can be disconnected from the side wall of the panel 20. By pressing the actuator 51, the actuator 51 can be deformed inward.

[0051] One end of the connecting part 52 can be connected to the end of the actuating part 51 near the hook part 53, and the other end can be connected to the end of the hook part 53 near the actuating part 51. The connecting part 52 can be parallel to the side of the panel 20 near the housing 10, and the connecting part 52 is disconnected from the side of the panel 20 near the housing 10. By pressing the actuating part 51, the connecting part 52 can be moved towards the actuating part 51.

[0052] The end of the hook portion 53 near the actuating portion 51 is connected to the connecting portion 52. The hook portion 53 can be parallel to the side wall of the housing 10, and the hook portion 53 is disconnected from the side wall of the housing 10. Then, by pressing the actuating portion 51, the hook portion 53 can be deformed in the direction closer to the housing 10 through the connecting portion 52.

[0053] The hook portion 53 has a hook at the end away from the actuator portion 51. The side of the hook away from the actuator portion 51 has a certain angle with the side wall of the housing 10, and the side of the hook away from the actuator portion 51 is inclined towards the panel 20, so that the hook can enter the battery compartment 03.

[0054] Thus, when installing the drone battery assembly 00 onto the drone 01, the housing 10 needs to be pushed into the battery compartment 03 of the drone 01. During this pushing process, when the hook portion 53 of the latching structure 50 contacts the side wall of the battery compartment 03, the hook portion 53 will be squeezed by the side wall of the battery compartment 03 and deform towards the housing 10, causing the connecting portion 52 and the actuating portion 51 to also deform. As the housing 10 continues to be pushed in, the hook portion 53 will extend into the groove 04 on the side wall of the battery compartment 03 under its own stress. The hook portion 53 and the groove 04 cooperate and lock together, thereby connecting and fixing the battery of the drone 01 to the battery compartment 03. At this time, the hook portion 53 will not be squeezed, and the hook portion 53, the connecting portion 52, and the actuating portion 51 will not deform.

[0055] Additionally, when the battery needs to be removed from the drone 01, the actuating part 51 of the latching structure 50 can be pressed to deform it inward. This causes the hook part 53 to move closer to the housing 10 via the connecting part 52, separating the hook part 53 from the groove 04 on the side wall of the battery compartment 03. Simultaneously, the user can pull the housing 10 out of the battery compartment 03. The design of the latching structure 50 makes the battery of the drone 01 easy to install and remove, thus adapting to various charging environments and improving the user experience.

[0056] When the latching structure 50 is pressed or squeezed by the side wall of the battery compartment 03 of the drone 01, the hook portion 53 will deform towards the housing 10. If the pressure is large, causing the hook portion 53 to deform significantly, the hook portion 53 may break. Alternatively, the actuator portion 51 may also deform significantly and break. Therefore, referring to FIG3, the housing 10 of the drone battery assembly 00 provided in this embodiment has a pair of retaining portions 60 for protecting the latching structure 50.

[0057] Two retaining parts 60 are located on both sides of the housing 10 and connected to the side walls of the housing 10. The retaining parts 60 can be parallel to the side walls of the housing 10, and the positions of the retaining parts 60 and the hook parts 53 of the latching structure 50 correspond one-to-one. The two retaining parts 60 are located inside the two hook parts 53, that is, the retaining parts 60 are closer to the housing 10 than the hook parts 53. When the latching structure 50 is in the released state, there is a gap between the hook parts 53 and the retaining parts 60, and the retaining parts 60 will not affect the hook parts 53 at this time. When it is necessary to push the battery into the battery compartment 03 of the drone 01, when the hook parts 53 of the latching structure 50 are squeezed by the side wall of the battery compartment 03 and deformed significantly towards the housing 10, the hook parts 53 will contact the retaining parts 60. The retaining parts 60 can prevent the hook parts 53 from continuing to deform inward and breaking. Similarly, when the battery needs to be removed from the battery compartment 03, the user needs to press the actuating part 51 of the buckle structure 50, so that the hook part 53 is deformed towards the housing 10 through the connecting part 52. If the user applies a large pressure, the hook part 53 will deform to a large extent and will contact the retaining part 60, thereby preventing it from continuing to deform inward and breaking.

[0058] Referring to Figure 1, the housing 10 of the drone battery assembly 00 may include a protrusion 11 adjacent to the panel 20, and the orthographic projection area of ​​the protrusion 11 on the housing 10 is located within the orthographic projection area of ​​the panel 20 on the housing 10. The drone battery assembly 00 also includes a power supply interface 40 disposed on the surface of the protrusion 11 opposite to the panel 20. The power supply interface 40 has multiple sockets 41 arranged in a row. Referring to Figure 6, the drone body 02 has a power interface 06 corresponding to the power supply interface 40. The power interface 06 has multiple inserts 061 that can adapt to the shape of the multiple sockets 41. The power interface 06 is adapted to connect to the power supply interface 40, and the multiple inserts 061 of the power interface 06 are inserted one-to-one into the multiple sockets 41 of the power supply interface 40, thereby supplying power to the drone 01.

[0059] As shown in Figure 4, a guide groove 12 is provided on the housing 10 of the drone battery assembly 00. The guide groove 12 extends from the first end of the housing 10 to the second end of the housing 10. The first end of the housing 10 is the end face where the panel 20 is located, and the second end of the housing 10 is the end face opposite to the end face where the panel 20 is located. Referring to Figure 6, guide protrusions 08 are provided at relative positions on the side wall of the battery compartment 03 of the drone 01. These protrusions can adapt to the shape of the guide groove 12 and extend towards the inside of the battery compartment 03. When the drone battery assembly 00 needs to be inserted into the battery compartment 03, the second end of the housing 10 enters the battery compartment 03 before the first end. The guide groove 12 has a guide opening 13 at the second end of the housing 10, which facilitates the guide protrusion 08 to extend into the guide groove 12. The guide groove 12 plays a good guiding and limiting role for the housing 10. As more and more of the guide protrusion 08 extends into the guide groove 12, the housing 10 is continuously pushed into the battery compartment 03 along the direction of the guide protrusion 08 until the snap-fit ​​structure 50 on the housing 10 engages with the groove 04 on the side wall of the battery compartment 03 to lock together, thereby fixing the battery connection in the battery compartment 03.

[0060] If the guide groove 12 of the housing 10 and the power supply interface 40 are located on the same side of the housing 10, it will be difficult to observe the connection between the power supply interface and the power interface 06 on the UAV 01 when the guide groove 12 and the guide protrusion 08 cooperate to guide the housing 10 into the battery compartment 03.

[0061] As shown in Figure 4, in this embodiment, the guide groove 12 of the housing 10 is located on the bottom surface of the housing 10, which is located between the two sides of the housing 10, that is, the side of the housing 10 closest to the ground. The power supply interface 40 is located on the top surface of the housing 10, with the top surface opposite to the bottom surface; that is, the guide groove 12 and the power supply interface 40 are opposite each other. Thus, during the process of the guide groove 12 guiding the housing 10 into the battery compartment 03, the user can easily observe the connection between the power supply interface 40 and the power consumption interface 06 on the top surface of the housing 10.

[0062] In summary, this application provides a drone battery assembly, including a housing, a panel, a charging interface, a power supply interface, and a pair of snap-fit ​​structures. The drone battery is located inside the housing, and the two snap-fit ​​structures are located on both sides of the housing. When installing the battery onto the drone, the housing of the drone battery assembly needs to be pushed into the drone's battery compartment. The hooks of the two snap-fit ​​structures are squeezed by the side wall of the battery compartment and deform towards the housing. At the same time, a corresponding retaining part is provided on the inner side of the hook to prevent the hook from breaking due to excessive deformation. Continuing to push the housing, the hooks can extend into the grooves on the side wall of the battery compartment under their own stress, and lock with the grooves, thereby connecting and fixing the drone battery to the battery compartment together. This allows the drone to be stored in a drone hangar for charging when not in use. When it is necessary to remove the battery, pressing the actuating part of the snap-fit ​​structure can cause the hooks to deform inward, separating the hooks from the grooves. At the same time, the housing can be pulled out of the battery compartment, and the battery can be removed. The battery can then be connected to a portable charging plug for charging. This snap-fit ​​structure makes it easy to install and remove the drone's battery, adapting to various charging environments and improving the user experience. Meanwhile, a guide groove is provided on the bottom surface of the shell, which guides and limits the insertion of the shell into the battery compartment. A power supply interface is located on the top surface of the shell, positioned opposite the guide groove, facilitating observation of the connection between the power supply interface and the drone's power interface.

[0063] Referring to Figure 5, this application embodiment provides a drone 01, which includes a drone body 02 and any of the aforementioned drone battery components 00. The drone battery component 00 is adapted to connect to the drone body 02. As shown in Figure 6, the drone body 02 has a battery compartment 03, and each of the two opposing inner walls of the battery compartment 03 has a groove 04. These grooves 04 correspond one-to-one with the snap-fit ​​structures 50 of the drone battery component 00. The hook portion 53 of the snap-fit ​​structure 50 can extend into the groove 04 and engage with it to lock it in place, thereby connecting the drone battery component 00 to the drone body 02. The engagement of the snap-fit ​​structure 50 and the groove 04 facilitates the installation and removal of the drone 01's battery, adapts to various charging environments, and enhances the user experience.

[0064] The drone body 02 is equipped with a power interface 06, which can be connected to the power supply interface 40 of the drone battery assembly 00. Referring to Figure 6, a retaining part 05 extends downward from the top wall of the battery compartment 03 of the drone body 02. The retaining part 05 is spaced from the entrance end of the battery compartment 03, meaning it is located inside the battery compartment 03. The power interface 06 is located on the surface of the retaining part 05 facing the entrance end of the battery compartment 03. Thus, the power interface 06 is not exposed but located inside the battery compartment 03, effectively protecting it. The power interface 06 has multiple prongs 061 arranged in a row. The power interface 06 is suitable for connection with the power supply interface 40 of the drone battery assembly 00. The multiple prongs 061 of the power interface 06 can be inserted one-to-one into the multiple sockets 41 of the power supply interface 40, thereby supplying power to the drone 01.

[0065] Referring to Figures 1 and 6, the housing 10 of the drone battery assembly 00 provided in this embodiment includes a protrusion 11. The protrusion 11 is adjacent to the panel 20, and the orthographic projection area of ​​the protrusion 11 on the housing 10 is located within the orthographic projection area of ​​the panel 20 on the housing 10. The power supply interface 40 is disposed on the protrusion 11. Correspondingly, the retaining portion 05 of the drone body 02 is located inside the battery compartment 03. Thus, when the drone battery assembly 00 is inserted into the battery compartment 03, the protrusion 11 can enter the battery compartment 03 and contact the retaining portion 05. The power supply interface 40 on the protrusion 11 can connect with the power interface 06 on the retaining portion 05. The panel 20 of the drone battery assembly 00 does not enter the battery compartment 03 but connects to the outer shell of the battery compartment 03, thereby enclosing the battery compartment 03 and the battery in the drone 01, effectively protecting the battery and the connection between the power supply interface 40 and the power interface 06.

[0066] As shown in Figure 7, the UAV body 02 has an electronic speed controller 07, which is connected to the motors of the UAV 01 and the power interface 06. The power interface 06 is connected to the power supply interface 40 of the UAV battery pack 00, allowing the electronic speed controller 07 to draw power from the battery of the UAV battery pack 00 to provide the necessary power to the motors of the UAV 01, control the output power of the motors, and thus power the entire UAV 01. Simultaneously, the electronic speed controller 07 can also control the rotational speed and direction of the motors to meet the flight requirements of the UAV 01 and improve its flight performance.

[0067] Referring to Figure 6, the bottom surface of the battery compartment 03 of the drone body 02 is provided with a guide ridge 08, the extension direction of which is the same as the insertion direction of the drone battery assembly 00. The bottom surface of the housing 10 of the drone battery assembly 00 is provided with a guide groove 12, which can adapt to the shape of the guide ridge 08. When the drone battery assembly 00 is inserted into the battery compartment 03, the guide ridge 08 can extend into the guide groove 12, allowing the drone battery assembly 00 to be inserted into the battery compartment 03 along the extension direction of the guide ridge 08, thus playing a good guiding and limiting role.

[0068] In summary, this application provides a drone, including a drone body and any of the drone battery components provided in this application. The two opposing inner walls of the drone body's battery compartment each have a groove that can engage with a pair of snap-fit ​​structures of the drone battery component for locking, making battery installation and removal convenient, adaptable to various charging environments, and improving the user experience. The drone body has a power interface that can connect to the power supply interface of the drone battery component to power the entire drone. Simultaneously, the bottom surface of the drone body's battery compartment has guide ridges that can extend into the guide grooves of the drone battery component, allowing the drone battery component to be inserted into the battery compartment along the direction of the guide ridges, providing good guidance and positioning.

[0069] Please refer to Figure 8. This application embodiment also provides a drone charging system 100, including a helipad 200 and any of the aforementioned drones 01. The helipad 200 is located in a drone hangar. When the hangar is open, the drone 01 can enter the hangar and land on the helipad 200 for parking.

[0070] The helipad 200 may include a centering mechanism 300, which may include multiple centering limit levers 301. As shown in Figure 9, the centering mechanism 300 may include four centering limit levers 301, which are arranged in pairs opposite each other and located at the four boundaries of the helipad 200. Each centering limit lever 301 has its two ends connected to a corresponding control lever, meaning each centering limit lever 301 corresponds to a pair of control levers. Each control lever has its own track on the helipad 200, and can move within its own track. In this configuration, in the direction perpendicular to the apron 200, the distance between two opposing centering limit levers 301 and the apron 200 is the same, while the heights of two non-opposing centering limit levers 301 from the apron 200 are different. That is, the distances between two adjacent centering limit levers 301 and the apron 200 are different, thus preventing collisions between non-opposing centering limit levers 301 during centering. The tracks of the pair of control levers corresponding to each centering limit lever 301 extend in the same direction and have the same length. The extension direction of the tracks is the length direction of the tracks, which is perpendicular to the length direction of the connected centering limit levers 301. The two tracks are located on opposite sides of the apron 200. Initially, each control lever is located at the end of its respective track closest to the boundary of the apron 200.

[0071] As shown in Figure 9, after UAV 01 lands on the helipad 200, it will be positioned within the rectangle formed by the four centering limit rods 301. Activating the centering mechanism 300 causes each pair of control levers to move along the extension direction of the track, thereby moving the connected centering limit rods 301 towards the center of the helipad 200. Under the combined action of the four centering limit rods 301, UAV 01 is confined to the center of the helipad 200, achieving centering. At this point, the centering limit rods 301 stop moving, clamping UAV 01 to prevent it from shaking during operation. As shown in Figure 8, for UAV 01, the front and rear centering limit rods 301 prevent it from shaking forward and backward, while the left and right centering limit rods 301 prevent it from shaking left and right.

[0072] Referring to Figure 8, the drone charging system 100 may also include a limiting mechanism 400, which is adapted to connect between the drone 01 and the landing pad 200. The top of the limiting mechanism 400 has multiple latching structures, and the bottom of the drone 01 has multiple grooves corresponding to these latching structures. The latching structures can extend into the grooves, thus allowing the limiting mechanism 400 to be installed on the bottom of the drone 01. When the drone 01 needs to be parked in a drone hangar, the drone 01 and the limiting mechanism 400 land together on the landing pad 200 of the hangar. Under the action of the centering mechanism 300, the drone 01 and the limiting mechanism 400 are restrained at the center of the landing pad 200. The bottom side of the limiting mechanism 400 has a tapered flange. During the centering process, the tapered flange is pressed under the centering limiting rod 301, thereby fixing the limiting mechanism 400 and the drone 01 on the landing pad 200 and preventing the drone 01 from bouncing up and down during operation.

[0073] Referring to Figure 9, the centering mechanism 300 of the drone charging system 100 also includes a charging plug 302. The charging plug 302 can be located at the center of a centering limit rod 301, and the charging plug 302 is opposite to the side of the drone battery assembly 00 of the drone 01 that has a charging interface 30. As shown in Figure 10, the charging plug 302 has multiple plug contacts 303, and the charging interface 30 of the drone battery assembly 00 has multiple interface contacts 32. When the centering mechanism 300 is activated, the charging plug 302 on the centering limit rod 301 moves together with the centering limit rod 301 toward the center of the landing pad 200, centering the drone 01. After centering, the charging plug 302 is precisely aligned with the charging interface 30 of the drone 01. The multiple plug contacts 303 of the charging plug 302 are electrically connected to the multiple interface contacts 32 of the charging interface 30 one-to-one. At the same time, the charging plug 302 is connected to a power source, thereby charging the drone 01. Furthermore, since the drone 01 is restricted to the center of the landing pad 200 by the centering mechanism 300, and the charging plug 302 is also connected to the centering limit rod 301, the drone 01 and the charging plug 302 can avoid bumps during the journey, thus making the connection between the drone 01 and the charging plug 302 tighter and more stable, ensuring the stability of the charging process.

[0074] The drone hangar is equipped with a communication module, such as a wireless network communication module or a Bluetooth communication module. The charging status of Drone 01 on the helipad 200 in the drone hangar can be transmitted to a mobile phone or vehicle-mounted system via the communication module, allowing users to conveniently monitor the charging status of Drone 01 in real time.

[0075] In summary, this application provides a drone charging system comprising a landing pad and a centering mechanism. This allows the drone to land on the landing pad in a drone hangar when idle, while the centering mechanism centers the drone and confines it to the center of the landing pad, preventing it from shaking during transport. Furthermore, a charging plug is installed on the centering limit rod of the centering mechanism, which can connect to the drone's charging port. This allows the drone to charge even when idle in the drone hangar. The centering mechanism's constraint ensures a tighter and more secure connection between the drone and the charging plug, thus guaranteeing a stable charging process.
