[0035] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0036] The embodiments of the present application provide a drone battery assembly that can solve the problem that drone batteries are difficult to disassemble.

[0037] Please refer to Figure 1 and Figure 2 The drone battery assembly 00 includes a housing 10, a panel 20, a charging port 30, a power supply port 40, and a pair of snap-fit ​​structures 50. The drone 01's battery is located within the housing 10. The panel 20 is located at a first end of the housing 10 and is connected to the drone 01's battery. The charging port 30 is located on the panel 20 and is adapted to connect to a charging socket, which can be a charging plug 302, to charge the battery.

[0038] like Figure 2As shown, the charging interface 30 may include a recessed area 31 and multiple interface contacts 32. The multiple interface contacts 32 are located in the recessed area 31, and the charging plug 302 has multiple plug contacts 303 corresponding to the multiple interface contacts 32. When charging the drone 01, the recessed area 31 of the charging interface 30 can be coupled with the charging plug 302, and the multiple interface contacts 32 of the charging interface 30 are electrically connected to the multiple plug contacts 303 of the charging plug 302 in a one-to-one correspondence. At the same time, the charging plug 302 is connected to a power source, thereby charging the drone 01. The charging interface 30 may further include two magnetic portions 33, which may be rectangular and located on either side of the plurality of interface contacts 32. The charging plug 302 may have two corresponding magnetic portions. When the charging interface 30 is coupled with the charging plug 302, the two magnetic portions 33 may be attracted to the two magnetic portions of the charging plug 302, so that the charging interface 30 and the charging plug 302 are more tightly connected, so that the interface contacts 32 and the plug contacts 303 can be in better and more stable contact, thereby reducing the problem of poor contact during charging.

[0039] like Figure 1 As shown, the power supply interface 40 can be located on the housing 10, facing away from the panel 20. The power supply interface 40 has multiple sockets 41. The drone 01 has a power interface 06 corresponding to the power supply interface 40. The power interface 06 has multiple plugs 061. When the drone 01 needs power, the power interface 06 is connected to the power supply interface 40. The multiple plugs 061 of the power interface 06 are plugged into the multiple sockets 41 of the power supply interface 40 in a one-to-one correspondence, thereby providing power to the drone 01.

[0040] Please refer to Figure 1 The housing 10 may also have a pair of snap-fit ​​structures 50, one located on either side of the housing 10. The battery compartment 03 of the drone 01 has grooves at corresponding positions. When the housing 10 is pushed into the battery compartment 03, the two snap-fit ​​structures 50 are squeezed and deformed. Further pushing of the housing 10 causes the two snap-fit ​​structures 50 to extend into the groove 04 under their own stress, locking with the groove 04 and thereby connecting the drone 01 battery to the battery compartment 03. To remove the battery, press the snap-fit ​​structures 50 to separate them from the groove 04, and then pull the housing 10 out of the battery compartment 03.

[0041] In summary, the drone battery assembly provided in the embodiments of the present application includes a housing, a panel, a charging port, a power supply port, and a pair of snap-on structures. The drone's battery is located within the housing, with two snap-on structures located on either side of the housing. The drone's battery compartment has grooves that mate with the snap-on structures at corresponding positions. To install the battery on a drone, the housing of the drone battery assembly is pushed into the drone's battery compartment. The two snap-on structures of the housing are squeezed by the sidewalls of the battery compartment and deform toward the housing. As the housing is pushed further, the two snap-on structures, under their own stress, extend into the grooves of the battery compartment. The snap-on structures lock tightly with the grooves, thereby connecting and securing the drone's battery to the battery compartment. This allows the drone to be placed in a drone hangar for charging when idle. To remove the battery, the snap-on structures are pressed to separate them from the grooves, and the housing is simultaneously pulled out of the battery compartment to remove the battery. The battery can then be connected to a portable charging plug for separate charging. This snap-on structure makes drone battery installation and removal more convenient, adapting to various charging environments and improving the user experience.

[0042] like Figure 2 As shown, the panel 20 of the drone battery assembly 00 may also include a pair of recessed structures 21, the two recessed structures 21 being 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. Figure 5 The sides of the two recessed structures on the drone body 02 can be aligned with the sides of the two recessed structures 21 of the drone battery assembly 00. These two recessed structures can then be combined with the two recessed structures 21 of the drone battery assembly 00 to form two new recessed structures 22, which can guide and limit the insertion of the drone battery assembly 00 into the drone body 02. Furthermore, the two newly formed recessed structures 22 can be coupled with two fastening structures of matching shape, further ensuring a secure connection between the drone battery assembly 00 and the drone body 02.

[0043] like Figure 3 As shown, the buckle structure 50 includes an actuating portion 51, a connecting portion 52, and a hook portion 53. The actuating portion 51 is closer to the first end of the housing 10 than the hook portion 53, that is, the actuating portion 51 is closer to the panel 20 than the hook portion 53, and the actuating portion 51 protrudes outward relative to the hook portion 53. The actuating portion 51 is connected to the housing 10, and the connecting portion 52 is used to connect the actuating portion 51 and the hook portion 53 together. Neither the connecting portion 52 nor the hook portion 53 is connected to the housing 10, thereby making the buckle structure 50 elastic.

[0044] Please refer to Figure 3 When installing the drone battery assembly 00 on the drone 01, the shell 10 needs to be pushed into the battery compartment 03 of the drone 01. During the pushing process, when the hook portion 53 of the snap structure 50 enters the battery compartment 03, the hook portion 53 will be squeezed by the side wall of the battery compartment 03 and deformed in the direction close to the shell 10. The shell 10 is further pushed and the hook portion 53, under the action of its own stress, will extend into the groove 04 on the side wall of the battery compartment 03. The hook portion 53 and the groove 04 cooperate and lock, thereby connecting and fixing the battery of the drone 01 to the battery compartment 03. When the battery needs to be removed from the drone 01, the actuator portion 51 of the snap structure 50 is pressed. The actuator portion 51 drives the hook portion 53 toward the shell 10 through the connecting portion 52, so that the hook portion 53 is separated from the groove 04 on the side wall of the battery compartment 03. At the same time, the user can drag the shell 10 out of the battery compartment 03. The design of the snap structure 50 makes it easy to install and remove the battery of the drone 01, thereby being able to adapt to various charging environments and improving the user experience.

[0045] When the buckle 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 toward the shell 10. If the pressure is large, the hook portion 53 will deform to a large extent and may break. Figure 3 The housing 10 of the drone battery assembly 00 provided in the embodiment of the present application has a pair of buckle portions 60 for protecting the buckle structure 50.

[0046] The two stoppers 60 are located on either side of the housing 10, corresponding one-to-one to the positions of the hook portions 53 of the snap structure 50. The two stoppers 60 are located on the inner sides of the two hook portions 53, which means that the stoppers 60 are closer to the housing 10 than the hook portions 53. When the snap structure 50 is in a released state, there is a gap between the hook portions 53 and the stoppers 60, and the stoppers 60 do not affect the hook portions 53. When the battery needs to be pushed into the battery compartment 03 of the drone 01, the hook portion 53 of the snap structure 50 is squeezed by the side wall of the battery compartment 03 and deforms significantly toward the housing 10. The hook portion 53 will then contact the stoppers 60, which prevents the hook portion 53 from further deforming inward and breaking. Similarly, when the battery needs to be removed from the battery compartment 03, the user needs to press the actuating portion 51 of the snap structure 50, thereby driving the hook portion 53 to deform toward the direction close to the shell 10 through the connecting portion 52. If the pressure applied by the user is large, the hook portion 53 will deform to a large extent, and the hook portion 53 will contact the blocking portion 60, thereby preventing it from continuing to deform inward and break.

[0047] Please refer to Figure 1The housing 10 of the drone battery assembly 00 may include a protrusion 11, which 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 drone battery assembly 00 also includes a power supply interface 40, which is provided on the surface of the protrusion 11 facing away from the panel 20. The power supply interface 40 has a plurality of sockets 41, which are arranged in a row. The drone body has a power interface 06 corresponding to the power supply interface 40, which has a plurality of plugs 061 and can adapt to the shapes of the plurality of sockets 41. The power interface 06 is suitable for connecting to the power supply interface 40, and the plurality of plugs 061 of the power interface 06 are inserted into the plurality of sockets 41 of the power interface 40 in a one-to-one correspondence, thereby supplying power to the drone 01.

[0048] like Figure 4 As shown, the housing 10 of the drone battery assembly 00 is provided with a guide groove 12. 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. Guide ridges are provided at relative positions on the side walls of the battery compartment 03 of the drone 01. These ridges are adapted to the shape of the guide grooves 12 and extend toward the interior 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 insertion of the guide ridges into the guide groove 12. The guide groove 12 plays a good guiding and limiting role for the shell 10. As more and more parts of the guide ridge extend into the guide groove 12, the shell 10 continues to advance into the battery compartment 03 along the direction of extension of the guide ridge until the snap structure 50 on the shell 10 cooperates and locks with the groove 04 on the side wall of the battery compartment 03, thereby fixing the battery connection in the battery compartment 03.

[0049] If the guide groove 12 of the shell 10 and the power supply interface 40 are set on the same side of the shell 10, when the guide groove 12 cooperates with the guide ridge to guide the shell 10 into the battery compartment 03, it is not convenient to observe the docking of the power supply interface and the power interface 06 on the drone 01.

[0050] like Figure 4As shown, in the embodiment of the present application, the guide groove 12 of the housing 10 is located on the bottom surface of the housing 10, which is located between the two side surfaces 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 and the bottom surface arranged opposite each other. In other words, the guide groove 12 and the power supply interface 40 are arranged opposite each other. In this way, as the guide groove 12 guides the housing 10 into the battery compartment 03, the user can also easily observe the connection between the power supply interface 40 and the power interface 06 on the top surface of the housing 10.

[0051] In summary, embodiments of the present application provide a drone battery assembly comprising a housing, a panel, a charging port, a power supply port, and a pair of snap structures. The drone's battery is located within the housing, with two snap structures located on either side of the housing. To install the battery on a drone, the housing of the drone battery assembly is pushed into the drone's battery compartment. The hooks of the two snap structures are squeezed by the sidewalls of the battery compartment, deforming toward the housing. Corresponding catches are provided on the inner sides of the hooks to prevent them from deforming excessively and breaking. As the housing is further pushed, the hooks, under their own stress, extend into grooves in the sidewalls of the battery compartment, locking into place. This secures the drone's battery to the battery compartment, allowing the drone to be placed in a drone hangar for charging when idle. To remove the battery, the actuator of the snap structure is pressed, causing the hooks to deform inward, separating them from the grooves. Simultaneously, the housing is pulled out of the battery compartment, allowing the battery to be removed and connected to a portable charging plug for separate charging. This snap-on structure makes it easier to install and remove the drone's battery, adapting to a variety of charging environments and enhancing the user experience. The bottom of the housing is also equipped with a guide groove, which guides and limits the insertion of the housing into the battery compartment. A power supply port is located on the top of the housing, facing the guide groove, making it easier to observe the connection between the power port and the power port on the drone.

[0052] Please refer to Figure 5 The embodiment of the present application provides a drone 01, which includes a drone body 02 and any of the above drone battery components 00, and the drone battery component 00 is suitable for connecting to the drone body 02. Figure 6As shown, the drone body 02 has a battery compartment 03. Two opposing inner walls of the compartment each have a groove 04, which corresponds one-to-one with the snap-fit ​​structure 50 of the drone battery assembly 00. The hook 53 of the snap-fit ​​structure 50 fits into the groove 04 and locks with it, thereby connecting the drone battery assembly 00 to the drone body 02. The combination of the snap-fit ​​structure 50 and the groove 04 facilitates installation and removal of the drone battery, adapting to various charging environments and enhancing the user experience.

[0053] The drone body 02 is provided with a power interface 06, which can be combined with the power supply interface 40 of the drone battery assembly 00. Figure 6 The top wall of the battery compartment 03 of the drone body 02 has a blocking portion 05 extending downward. There is a certain distance between the blocking portion 05 and the entrance end of the battery compartment 03, that is, the blocking portion 05 is located inside the battery compartment 03. The power interface 06 is provided on the surface of the blocking portion 05 facing the entrance end of the battery compartment 03. In this way, the power interface 06 is not exposed to the outside, but is located inside the battery compartment 03, thereby effectively protecting the power interface 06. The power interface 06 has multiple plugs 061, which are arranged in a row. The power interface 06 is suitable for combining with the power supply interface 40 of the drone battery assembly 00. The multiple plugs 061 of the power interface 06 can be inserted into the multiple jacks 41 of the power supply interface 40 in a one-to-one correspondence, thereby providing power to the drone 01.

[0054] Please refer to Figure 1 and Figure 6 The housing 10 of the drone battery assembly 00 provided in the embodiment of the present application includes a raised portion 11. The raised portion 11 is adjacent to the panel 20, and the orthographic projection of the raised portion 11 on the housing 10 is located within the orthographic projection of the panel 20 on the housing 10. The power supply interface 40 is provided on the raised portion 11. Correspondingly, the stopper 05 of the drone body 02 is located inside the battery compartment 03. Therefore, when the drone battery assembly 00 is inserted into the battery compartment 03, the raised portion 11 can enter the battery compartment 03 and contact the stopper 05, allowing the power supply interface 40 on the raised portion 11 to mate with the power supply interface 06 on the stopper 05. The panel 20 of the drone battery assembly 00 does not enter the battery compartment 03, but instead mates with the outer shell of the battery compartment 03, thereby enclosing the battery compartment 03 and the battery within the drone 01, effectively protecting the battery and the connection between the power supply interface 40 and the power supply interface 06.

[0055] like Figure 7As shown, drone body 02 includes an electronic speed controller 07, which is connected to drone 01's motor and power interface 06. Power interface 06 interfaces with power interface 40 of drone battery assembly 00. This allows electronic speed controller 07 to draw power from the batteries in drone battery assembly 00 to supply the required power to drone 01's motor, controlling the motor's output power and thus powering the entire drone 01. Electronic speed controller 07 can also control the motor's rotational speed and direction, meeting drone 01's flight requirements and improving flight performance.

[0056] Please refer 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 the guide ridge 08 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. The guide groove 12 is adapted 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, providing a good guiding and limiting effect.

[0057] In summary, the embodiments of the present application provide a drone, comprising a drone body and any one of the drone battery assemblies provided in the embodiments of the present application. The two opposing inner walls of the battery compartment of the drone body each have a groove, which can be locked with a pair of snap structures of the drone battery assembly, thereby making the installation and removal of the drone battery more convenient, adapting to a variety of charging environments, and improving the user experience. The drone body is provided with an electrical interface, which can be docked with the power supply interface of the drone battery assembly to power the entire drone. At the same time, the bottom surface of the battery compartment of the drone body is provided with a guide rib, which can be extended into the guide groove of the drone battery assembly, so that the drone battery assembly can be inserted into the battery compartment along the direction in which the guide rib extends, playing a better guiding and limiting role.

[0058] Please refer to Figure 8 The embodiment of the present application further provides a drone charging system 100, comprising a helipad 200 and any of the above-mentioned drones 01. The helipad 200 is located in a drone hangar. When the hangar is opened, the drone 01 can enter the hangar and land on the helipad 200 for parking.

[0059] The apron 200 may include a centering mechanism 300, which may include a plurality of centering limit rods 301. Figure 9As shown, the centering mechanism 300 may include four centering stop rods 301, each located at the four edges of the apron 200. Each centering stop rod 301 is connected at both ends to a corresponding joystick, meaning each centering stop rod 301 corresponds to a pair of joysticks. Each joystick has its own track on the apron 200, allowing the joystick to move along its own track. The two centering stop rods 301 that face each other are at the same height from the apron 200, while the two non-facing centering stop rods 301 are at different heights from the apron 200, thereby preventing collision between the non-facing centering stop rods 301 during the centering process. The tracks of the pair of joysticks corresponding to each centering stop rod 301 extend in the same direction and have the same length. The track's direction of extension is the length of the track, which is perpendicular to the length of the centering stop rod 301 to which it is connected. The two tracks are located on opposite sides of the apron 200. Initially, each joystick is located at one end of its respective track close to the boundary of the apron 200 .

[0060] like Figure 9 As shown, after the drone 01 lands on the apron 200, the drone 01 will be located in the rectangle formed by the four centering limit rods 301. When the centering mechanism 300 is started, each pair of joysticks will move along the extension direction of the track, thereby driving the centering limit rods 301 connected thereto to move toward the center of the apron 200. Under the joint action of the four centering limit rods 301, the drone 01 is restricted to the center of the apron 200 and is centered. At this time, the centering limit rods 301 stop moving and clamp the drone 01 to prevent the drone 01 from bumping during driving. As shown Figure 8 As shown, for the drone 01, the two front and rear centering limit rods 301 can prevent the drone 01 from shaking forward and backward, and the two left and right centering limit rods 301 can prevent the drone 01 from shaking left and right.

[0061] Please refer to Figure 8The drone charging system 100 may also include a limiting mechanism 400, which is adapted to be connected between the drone 01 and the landing pad 200. The limiting mechanism 400 has multiple snap-fit ​​structures on its top, and multiple grooves corresponding to the snap-fit ​​structures on the bottom of the drone 01. The snap-fit ​​structures fit into the grooves, allowing the limiting mechanism 400 to be installed on the bottom of the drone 01. When the drone 01 needs to be parked in the drone hangar, the drone 01 and the limiting mechanism 400 are lowered onto the landing pad 200. The centering mechanism 300 restrains the drone 01 and the limiting mechanism 400 at the center of the landing pad 200. The side edges of the bottom of the limiting mechanism 400 are provided with tapered flanges. During the centering process, the tapered flanges are pressed under the centering limit rod 301, thereby securing the limiting mechanism 400 and the drone 01 on the landing pad 200 and preventing the drone 01 from bouncing around during operation.

[0062] Please refer to Figure 9 The centering mechanism 300 of the drone charging system 100 further includes a charging plug 302, which can be located at the center of a centering limit rod 301. The charging plug 302 is opposite to the side of the drone battery assembly 00 of the drone 01 having the charging interface 30. Figure 10 As shown, 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. After the drone 01 is centered, the charging plug 302 is 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 in a one-to-one correspondence. At the same time, the charging plug 302 is connected to a power source, thereby charging the drone 01. Furthermore, because the drone 01 is restrained to the center of the landing pad 200 by the centering mechanism 300 and the charging plug 302 is connected to the centering limit rod 301, the drone 01 and the charging plug 302 are protected from bumps during driving, thereby ensuring a tighter and more stable connection between the drone 01 and the charging plug 302, and a stable charging process.

[0063] The drone hangar has a communication module, such as a wireless network communication module or a Bluetooth communication module. The charging status of the drone 01 on the helipad 200 in the drone hangar can be transmitted to a mobile phone or a car computer via the communication module, thereby facilitating real-time monitoring of the charging status of the drone 01.

[0064] In summary, the embodiments of the present application provide a drone charging system, which includes a helipad and a centering mechanism, so that when a drone is idle, it can land on the helipad of the drone hangar and park. At the same time, the centering mechanism can center the drone and confine it to the center of the helipad to prevent the drone from bumping during driving. In addition, a charging plug is installed on the centering limit rod of the centering mechanism, and the charging plug can be docked with the charging port of the drone, so that the drone can be charged even when it is idle in the drone hangar. Due to the limitation of the centering mechanism, the connection between the drone and the charging plug can be guaranteed to be tighter and more stable, thereby ensuring the stability of the charging process.
