Drone charging interface components, charging plugs and charging systems

Abstract

This application discloses a drone charging interface, charging plug, and charging system, belonging to the technical field of drone charging. The drone charging interface includes a battery connection part and a charging interface part. The charging interface part includes multiple interface contacts and a recessed area. The multiple interface contacts are located in the recessed area, which is connected to the drone charging plug. Along the direction gradually moving away from the battery connection part, the cross-section of the recessed area gradually increases, thereby increasing the lateral area of ​​the recessed area and increasing the contact area between the recessed area and the drone charging plug. This increases the friction between the recessed area and the drone charging plug, making the connection between the drone charging interface and the drone charging plug tighter. The lateral side of the recessed area also has a good guiding and limiting function, allowing the drone charging plug to connect better with the multiple interface contacts in the recessed area, improving the problem of poor charging contact.

Description

[0001] This application claims priority to Chinese Patent Application No. 202411432332.7, filed on October 14, 2024, entitled “Unmanned Aerial Vehicle Charging Interface, Charging Plug and Charging System”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the technical field of drone charging, and in particular to a drone charging interface, charging plug and charging system. Background Technology

[0003] As a widely used flying device, drones are constantly evolving in form, structure, and function, and their applicable scenarios are also increasing. Drone endurance has become a crucial factor affecting the user experience. Because some drones consume significant power during flight and their locations are unpredictable, frequent and unscheduled charging is necessary, making the design of onboard charging devices essential.

[0004] In related technologies, wired charging is commonly used to charge drones. Compared to wireless charging, wired charging can improve the efficiency and safety of drone charging. Most charging limiting technologies in these technologies rely on mechanical clamping. During charging, mechanical clamping can effectively secure the drone and facilitate connection between the drone and the charging contacts.

[0005] However, the mechanical clamping structure in the relevant technology is relatively complex, making user operation complicated and unsuitable for vehicle-mounted environments. It is also prone to poor contact when charging drones, resulting in low charging efficiency. Summary of the Invention

[0006] This application provides a drone charging interface, charging plug, and charging system, which can reduce the problem of poor charging contact that is prone to occur in drone charging devices in related technologies. The technical solution is as follows:

[0007] On the one hand, a drone charging interface device is provided, which includes a connected battery connection part and a charging interface part;

[0008] The battery connection is adapted to be connected to the drone battery;

[0009] The charging interface is adapted to be connected to a drone charging plug;

[0010] The charging interface portion has a recessed area and multiple interface contacts, the multiple interface contacts being located in the recessed area, and the cross-section of the recessed area gradually increases along the direction gradually moving away from the battery connection portion.

[0011] Optionally, the cross-section of the recessed region is non-centrosymmetric to facilitate foolproof design.

[0012] Optionally, the cross-section of the recessed region is a rectangle with rounded corners on two adjacent sides.

[0013] Optionally, the recessed area is provided with a magnetic attraction part.

[0014] Optionally, the recessed area is provided with two magnetic suction parts, which are located on both sides of the plurality of interface contacts.

[0015] Optionally, the battery connection portion includes an opening and a latching portion, the latching portion extending from the edge of the opening in a direction away from the charging interface portion.

[0016] Optionally, the plurality of interface contacts may include at least two power contacts and at least two communication contacts.

[0017] On the other hand, a drone charging plug is provided, which is adapted to be connected to any of the drone charging interface devices described above to charge the drone battery. The drone charging plug includes a connected insertion portion and a holding portion. The insertion portion has plug contacts adapted to be connected to the plurality of interface contacts. The cross-section of the insertion portion gradually decreases in a direction gradually moving away from the holding portion.

[0018] Optionally, a spring pin is provided on the end face of the holding part opposite to the insertion part, and the spring pin extends from the holding part to the insertion part.

[0019] In another aspect, a drone charging system is provided, the drone charging system including a drone and any of the drone charging plugs described above, the drone including a drone battery and any of the drone charging interface components described above, the drone battery being connected to the battery connection portion of the drone charging interface component, and the drone charging plug being adapted to mate with the charging interface portion of the drone charging interface component.

[0020] The beneficial effects of the technical solution provided in this application include at least the following:

[0021] The charging interface of the drone charging connector has a recessed area. The cross-section of this recessed area gradually increases in the direction away from the battery connection, thereby increasing the lateral surface area of ​​the recessed area. This increases the contact area between the recessed area and the drone charging plug, thus increasing the friction between them and resulting in a tighter connection. The sides of the recessed area also provide better guidance and restraint, allowing the charging contacts of the drone charging plug to connect well with multiple interface contacts in the recessed area, improving the problem of poor charging contact. Simultaneously, the increased contact area effectively disperses the force exerted by the drone charging plug on the charging interface, thereby improving the charging interface's ability to withstand forces, ensuring a stable charging process, and improving drone charging efficiency. Furthermore, because the cross-section of the recessed area gradually increases in the direction away from the battery connection, this shape of the recessed area eliminates the need for precise alignment when inserting the drone charging plug. Therefore, this facilitates automated mechanical connection of the drone charging plug and the charging interface, avoiding excessively high mechanical requirements and effectively reducing the production and operating costs of automated machinery.

[0027] 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.

[0028] This application provides a drone charging interface that can reduce the problem of poor charging contact that is prone to occur in drone charging devices.

[0029] Please refer to Figure 1 The drone charging interface 10 includes a connected battery connection part 11 and a charging interface part 12. The battery connection part 11 is adapted to be connected to the drone battery 20, and the charging interface part 12 is adapted to be connected to the drone charging plug 30 so as to charge the drone.

[0030] like Figure 2 As shown, the charging interface portion 12 has a recessed area 121 and multiple interface contacts 122, with the multiple interface contacts 122 located in the recessed area 121. When charging the drone battery 20, the drone charging plug 30 is coupled to the recessed area 121 of the charging interface portion 12, and the drone charging plug 30 is connected to the multiple interface contacts 122 of the recessed area 121, thereby realizing charging.

[0031] Along the direction gradually moving away from the battery connection portion 11, the cross-section of the recessed region 121 of the charging interface portion 12 gradually increases. That is, along the direction gradually moving away from the battery connection portion 11, at least one side of the recessed region 121 extends in a direction gradually moving away from the plurality of interface contacts 122. Please refer to... Figure 2 The recessed area 121 can extend away from the ground on all sides in a direction away from the multiple interface contacts 122.

[0032] Of course, the drone charging plug 30 connected to the drone charging interface 10 can adapt to the shape of the recessed area 121. This increases the lateral surface area of ​​the recessed area 121, and consequently increases the contact area between the recessed area 121 and the drone charging plug 30, thereby increasing the friction between them and making the connection between the charging interface 12 and the drone charging plug 30 tighter. The increased contact area between the recessed area 121 and the drone charging plug 30 also better disperses the force exerted by the drone charging plug 30 on the charging interface 12, further ensuring the stability of the charging process. At the same time, the shape of the recessed area 121 eliminates the need for precise alignment before insertion of the drone charging plug 30, facilitating automated mechanical connection between the drone charging plug 30 and the charging interface 12.

[0033] In summary, the drone charging interface component provided in this application includes a connected battery connection portion and a charging interface portion. Along a direction gradually moving away from the battery connection portion, the cross-section of the recessed area of ​​the charging interface portion gradually increases, thereby increasing the lateral surface area of ​​the recessed area. This increases the contact area between the recessed area and the drone charging plug, thus increasing the frictional force between them. This results in a tighter connection between the charging interface portion and the drone charging plug. The lateral surface of the recessed area also provides better guidance and limiting, allowing the drone charging plug to connect better with multiple interface contacts in the recessed area, improving the problem of poor charging contact. Simultaneously, the increased contact area effectively disperses the force applied by the drone charging plug to the charging interface portion, thereby enhancing the charging interface portion's ability to withstand forces, ensuring a stable charging process, and improving drone charging efficiency. Furthermore, since the cross-section of the recessed area gradually increases in the direction away from the battery connection, when the drone charging plug is inserted into the recessed area, this shape of the recessed area means that the drone charging plug does not need to be precisely aligned before insertion. Therefore, this is also conducive to using mechanical automation to connect the drone charging plug and the charging interface, avoiding excessive mechanical requirements during automation, and effectively reducing the production and use costs of automated machinery.

[0034] In related technologies, drone charging structures are prone to reverse connection issues. If the cross-section of the recessed area 121 of the charging interface portion 12 is centrally symmetrical, then correspondingly, the cross-section of the portion of the drone charging plug 30 coupled to the recessed area 121 is also centrally symmetrical. Thus, when coupling the drone charging plug 30 to the recessed area 121, reverse connection of the drone charging plug 30 is likely to occur. The cross-section of the recessed area 121 of the drone charging interface 10 provided in this application embodiment can be non-centrally symmetrical. Only when the drone charging plug 30 is correctly adapted to the shape of the recessed area 121 can coupling between the drone charging plug 30 and the recessed area 121 be achieved, thereby preventing reverse connection of the drone charging plug 30 and facilitating foolproofing.

[0035] Optionally, the cross-section of the recessed region 121 can be a rectangle with two adjacent rounded corners, meaning the cross-section of the recessed region 121 is non-centrally symmetrical. Correspondingly, the cross-section of the drone charging plug 30 also has two adjacent rounded corners. Please refer to... Figure 2The two adjacent rounded corners of the cross-section of the recessed region 121 can be located on the side of the recessed region 121 away from the ground. Simultaneously, in a direction perpendicular to the ground, the side of the recessed region 121 away from the ground can protrude from the side of the recessed region 121 closest to the ground. Only when the two adjacent rounded corners of the cross-section of the drone charging plug 30 are located on the side of the drone charging plug 30 away from the ground can the drone charging plug 30 correctly adapt to the shape of the recessed region 121, thereby enabling coupling between the drone charging plug 30 and the recessed region 121 and preventing reverse connection.

[0036] The recessed area 121 of the drone charging interface 10 provided in this application embodiment can be provided with a magnetic part, and the drone charging plug 30 can also be provided with a magnetic part at the corresponding position. When the drone charging plug 30 is coupled with the recessed area 121, the magnetic part of the drone charging plug 30 and the magnetic part of the recessed area 121 can attract each other, thereby making the connection between the drone charging plug 30 and the drone charging interface 10 tighter and ensuring the stability of the drone charging process.

[0037] like Figure 2 As shown, the recessed area 121 of the drone charging interface 10 can be equipped with two magnetic suction parts 123. The two magnetic suction parts 123 can be rectangular and are located on both sides of the multiple interface contacts 122. The drone charging plug 30 can also be equipped with two magnetic suction parts corresponding to the two magnetic suction parts 123. Thus, when the drone charging plug 30 is coupled to the recessed area 121, the two magnetic suction parts of the drone charging plug 30 can respectively attract the two magnetic suction parts 123 of the recessed area 121, thereby making the connection between the drone charging plug 30 and the drone charging interface 10 tighter and further ensuring the stability of the drone charging process.

[0038] The battery connection portion 11 of the drone charging interface 10 is connected to the drone battery 20, thereby connecting the drone battery 20 to the drone charging interface 10 for charging the drone battery 20. Please refer to... Figure 3The battery connection portion 11 has a first surface 111 and a second surface 112 in a direction away from the charging interface portion 12. The first surface 111 is a surface close to the charging interface portion 12, and the second surface 112 is a surface away from the charging interface portion 12. The second surface 112 is connected to the drone battery 20. The orthographic projection area of ​​the second surface 112 on the charging interface portion 12 is smaller than the orthographic projection area of ​​the first surface 111 on the charging interface portion 12. That is, there is a non-overlapping area between the orthographic projections of the first surface 111 and the second surface 112 on the charging interface portion 12. This non-overlapping area is distributed on the first surface 111. The battery connection portion 11 may include an opening and a latching portion 113. The non-overlapping area of ​​the orthographic projections on the first surface 111 is the opening. The latching portion 113 is located on the side of the battery connection portion 11 and extends from the edge of the opening in a direction away from the charging interface portion 12. The battery connection portion includes at least two symmetrically positioned latching portions 113. The drone body has corresponding slots for locking, allowing the locking part 113 to extend into these slots and engage, thus securing the drone battery 20 and the drone charging interface 10 to the drone body. Alternatively, the locking part 113 can remain outside the slots, allowing the drone battery 20 and charging interface 10 to be removed from the drone body, making the drone battery 20 detachable. This allows the drone to be charged either directly on the drone or detached and charged separately, adapting to various charging environments and improving the user experience.

[0039] The drone charging interface 10 has at least two power contacts and at least two communication contacts, meaning the drone charging interface 10 has at least four interface contacts 122. The two power contacts can be one positive contact and one negative contact. The power contacts of the drone charging interface 10 are connected to the drone charging plug 30 for charging the drone battery 20. The communication contacts of the drone charging interface 10 are connected to the drone charging plug 30 for transmitting information about the drone battery 20, ensuring the smooth charging process of the drone battery 20.

[0040] In summary, this application provides a drone charging interface component. The charging interface portion of the drone charging interface component has a recessed area. The cross-section of the recessed area gradually increases in the direction gradually moving away from the battery connection portion, thereby increasing the lateral area of ​​the recessed area. This increases the contact area between the recessed area and the drone charging plug, and also increases the frictional force between them, resulting in a tighter connection between the charging interface portion and the drone charging plug. The sides of the recessed area also have good guiding and limiting functions, allowing the drone charging plug to connect well with multiple interface contacts in the recessed area, improving the problem of poor charging contact. The increased contact area also effectively disperses the force applied by the drone charging plug on the charging interface portion, thereby improving the charging interface portion's ability to withstand forces and ensuring stable charging. Simultaneously, the shape of the recessed area eliminates the need for precise alignment before insertion of the drone charging plug. Therefore, this facilitates automated mechanical operation to connect the drone charging plug and the charging interface portion, avoiding excessively high mechanical requirements during automated operation and effectively reducing the production and usage costs of automated machinery. Furthermore, the cross-section of the recessed area is non-centrally symmetrical, which helps prevent reverse connection of the drone charging plug. The recessed area can be equipped with a magnetic attachment, allowing for a tighter connection between the drone charging plug and the drone charging interface, further ensuring a stable charging process. The drone charging interface connects to the drone battery and features a latching part that extends into a latching slot on the drone body, enabling the drone battery to be detachable. This allows the drone to adapt to various charging environments, further enhancing the user experience.

[0041] Please refer to Figure 3 This application also provides a drone charging plug 30, which is adapted to connect to the drone charging interface 10 provided in this application. The drone charging plug 30 includes a connected gripping part 31 and an insertion part 32. The gripping part 31 facilitates the user or mechanical automation structure to hold the drone charging plug 30 for insertion or removal, and the insertion part 32 facilitates connection to the drone charging interface 10. When the drone charging plug 30 is inserted into the drone charging interface 10, the insertion part 32 extends into the recessed area 121, while the gripping part 31 is located outside the recessed area 121, facilitating gripping or connection to other mechanical components.

[0042] The insertion portion 32 has multiple plug contacts 321, which correspond to multiple interface contacts 122 of the drone charging interface 10. When the drone charging plug 30 is connected to the drone charging interface 10, the insertion portion 32 of the drone charging plug 30 is coupled to the recessed area 121 of the drone charging interface 10, and simultaneously, the multiple plug contacts 321 of the insertion portion 32 are electrically connected to the multiple interface contacts 122 of the recessed area 121 in a one-to-one correspondence.

[0043] The drone charging plug 30 has at least two power contacts and at least two communication contacts, meaning the drone charging plug 30 has at least four plug contacts 321. The two power contacts can be one positive contact and one negative contact. The power contacts of the drone charging plug 30 are connected to the power contacts of the drone charging interface 10 for charging the drone battery 20. The communication contacts of the drone charging plug 30 are connected to the communication contacts of the drone charging interface 10 for transmitting information about the drone battery 20, ensuring the smooth charging process of the drone battery 20.

[0044] The drone charging plug 30 provided in this application embodiment has a gradually decreasing cross-sectional area of ​​the insertion portion 32 along the direction gradually moving away from the gripping portion 31. That is, along the direction gradually moving away from the gripping portion 31, at least one side of the insertion portion 32 extends towards the plurality of plug contacts 321, thereby increasing the side surface area of ​​the insertion portion 32. For example... Figure 3 As shown, the sides of the insertion portion 32 away from the ground extend towards the plurality of plug contacts 321. The side of the insertion portion 32 near the ground can be flat. The sides of the recessed area 121 of the drone charging interface 10 away from the ground extend away from the plurality of interface contacts 122 and protrude from the side of the recessed area 121 near the ground. Thus, the insertion portion 32 can adapt to the shape of the recessed area 121 of the drone charging interface 10. When the drone charging plug 30 is connected to the drone charging interface 10, the insertion portion 32 of the drone charging plug 30 couples with the recessed area 121 of the drone charging interface 10. Please refer to... Figure 1 The insertion part 32 can partially enter the recessed area 121, and the side of the insertion part 32 closest to the ground may not enter the recessed area 121.

[0045] As the side area of ​​the insertion part 32 increases, and because the insertion part 32 can adapt to the shape of the recessed area 121 of the drone charging interface 10, the contact area between the insertion part 32 and the recessed area 121 of the drone charging interface 10 also increases. This increases the friction between the insertion part 32 and the recessed area 121, making the connection between the drone charging plug 30 and the drone charging interface 10 tighter. At the same time, the increased contact area can better disperse the force exerted by the drone charging plug 30 on the drone charging interface 10, thereby improving the drone charging interface 10's ability to withstand forces, ensuring the stability of the charging process, and improving the drone charging efficiency.

[0046] Since the cross-section of the recessed region 121 can be non-centrosymmetric, correspondingly, the cross-section of the insertion portion 32 can also be non-centrosymmetric. Please refer to... Figure 3 The cross-section of the insertion part 32 can be a rectangle with rounded corners on two adjacent sides. When the two rounded corners on the cross-section of the insertion part 32 are located on the side of the insertion part 32 away from the ground, the insertion part 32 can correctly adapt to the shape of the recessed area 121 of the drone charging interface 10, realize the coupling between the insertion part 32 and the recessed area 121, thereby achieving the effect of preventing reverse connection.

[0047] To facilitate connection with the drone charging interface 10 provided in this embodiment, the drone charging plug 30 may have a magnetic attachment portion. Please refer to... Figure 3 The insertion portion 32 of the drone charging plug 30 can be equipped with two magnetic suction portions 322, which can be rectangular and are located on both sides of the multiple plug contacts 321. Thus, when the insertion portion 32 of the drone charging plug 30 is coupled to the recessed area 121 of the drone charging interface 10, the two magnetic suction portions 322 of the insertion portion 32 can respectively attract the two magnetic suction portions 123 of the recessed area 121, thereby making the connection between the drone charging plug 30 and the drone charging interface 10 tighter and ensuring the stability of the drone charging process.

[0048] When the drone charging plug 30 is connected to the drone charging interface 10, the insertion part 32 of the drone charging plug 30 can partially enter the recessed area 121 of the drone charging interface 10, thereby achieving coupling. However, the gripping part 31 of the drone charging plug 30 does not enter the recessed area 121. The user can insert the drone charging plug 30 into the drone charging interface 10 or pull it out of the drone charging interface 10 by holding the gripping part 31. However, due to the coupling structure formed between the insertion part 32 and the recessed area 121, and the mutual attraction between the two magnetic parts 322 of the insertion part 32 and the two magnetic parts 123 of the recessed area 121, the connection between the insertion part 32 and the recessed area 121 is relatively tight. Therefore, it is not easy for the user to pull the drone charging plug 30 out of the drone charging interface 10 after charging is complete.

[0049] In this case, the drone charging plug 30 provided in this embodiment has a press-and-rebound structure, so that the user or related machinery can easily pull the drone charging plug 30 out of the drone charging interface 10. Please refer to... Figure 2 The holding portion 31 of the drone charging plug 30 has a spring-loaded pin 33 on its end face opposite to the insertion portion 32, extending from the holding portion 31 towards the insertion portion 32. The end face of the holding portion 31 opposite to the insertion portion 32 may have a blind hole, into which the spring-loaded pin 33 is inserted. Figure 4 As shown, the spring-loaded pin 33 may include a pin 331, a spring 332, and a housing 333. The spring 332 is located inside the housing 333. A portion of the pin 331 is connected to the spring 332 inside the housing 333, while the remaining portion is located outside the housing 333. When the drone battery 20 needs to be charged, the user can couple the insertion portion 32 with the recessed area 121 by holding the grip 31. At this time, the pin 331 is not under force, and the spring 332 is in a relaxed state inside the housing 333. After charging is complete, the user presses the end face of the holding part 31 away from the insertion part 32. The ejector pin 331 is subjected to force, and the spring 332 connected to the ejector pin 331 is compressed in the direction gradually approaching the insertion part 32. This gives the spring 332 stress in the direction gradually moving away from the insertion part 32. At this time, the user stops pressing the end face. The stress of the spring 332 causes the spring 332 to drive the ejector pin 331 to move in the direction gradually moving away from the insertion part 32, thereby popping the drone charging plug 30 out of the drone charging interface 10, making it convenient for the user to unplug and improving the user experience.

[0050] In summary, this application provides a drone charging plug, which includes a connected gripping portion and an insertion portion. The cross-section of the insertion portion gradually decreases along the direction away from the gripping portion, thereby increasing the lateral area of ​​the insertion portion. Furthermore, the insertion portion can adapt to the shape of the recessed area of ​​the drone charging interface, thus increasing the contact area between the insertion portion and the recessed area. This increases the friction between the insertion portion and the recessed area, resulting in a tighter connection between the drone charging plug and the drone charging interface, improving the problem of poor charging contact. The increased contact area also better disperses the force exerted by the drone charging plug on the drone charging interface, thereby improving the drone charging interface's ability to withstand forces, ensuring a stable charging process, and improving drone charging efficiency. Simultaneously, the cross-section of the insertion portion is non-centrally symmetrical, which prevents the drone charging plug from being reversed. The insertion portion may be equipped with a magnetic suction portion corresponding to the drone charging interface, allowing for a tighter connection between the drone charging plug and the drone charging interface, further ensuring the stability of the charging process. In addition, a spring pin is provided on the end face of the holding part of the drone charging plug away from the insertion part. When charging is complete, the user presses the pin, and the drone charging plug moves away from the insertion part under the stress of the spring, thereby popping the drone charging plug out of the drone charging interface, making it convenient for the user to unplug and thus improving the user experience.

[0051] This application also provides a drone charging system, which may include a drone and any of the aforementioned drone charging plugs 30. The drone may include a drone battery 20 and any of the aforementioned drone charging interface components 10. The drone charging interface component 10 includes a connected battery connection portion 11 and a charging interface portion 12. The drone battery 20 can be connected to the battery connection portion 11 of the drone charging interface component 10. The battery connection portion 11 has a latching portion 113, and the drone body has a latching slot. The latching portion 113 can extend into the latching slot on the drone body, thereby fixing the drone battery 20 and the drone charging interface component 10 to the drone body. Of course, the latching portion 113 may not extend into the latching slot on the drone body, thereby allowing the drone battery 20 to be removed from the drone body. The design of the latching portion 113 and the latching slot enables the drone battery 20 to be detachable. This allows drone users to charge the drone battery 20 directly on the drone or remove the drone battery 20 for separate charging, thus adapting to various charging environments and improving the user experience.

[0052] When charging the drone, the drone charging plug 30 is adapted to mate with the charging interface portion 12 of the drone charging interface component 10. The drone charging plug 30 includes a connected holding portion 31 and an insertion portion 32. The insertion portion 32 has multiple plug contacts 321, and the charging interface portion 12 of the drone charging interface component 10 has multiple interface contacts 122. During charging, the multiple plug contacts 321 of the drone charging plug 30 are electrically connected to the multiple interface contacts 122 of the drone charging interface component 10 in a one-to-one correspondence. At the same time, the drone charging plug 30 is connected to a power source to charge the drone.
