[0002] The present application relates to the technical field of charging of drones, and in particular to a drone charging interface, a charging plug and a charging system. Background Art

[0003] As a widely used flying device, drones are constantly evolving in form, structure and function, and their applicable scenarios are also increasing. The endurance of drones has become an important factor affecting the experience of using drones. Since some drones consume a lot of power during shooting flights and their whereabouts are not fixed, they need to be charged frequently and at irregular locations. Therefore, the design of an on-board charging device is imperative.

[0004] In the related art, the drone is usually charged by wired charging. Compared with wireless charging, wired charging can improve the efficiency and safety of drone charging. In the related art, most of the charging limit technologies are based on mechanical clamping. During the charging process, mechanical clamping can better fix the drone and facilitate the connection between the drone and the charging contacts.

[0005] However, the mechanical clamping structure in the related technology is relatively complex, and the user operation is complicated, which is not suitable for vehicle-mounted use. When charging the drone, poor contact is prone to occur, resulting in low charging efficiency. Summary of the invention

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

[0007] In one aspect, a drone charging interface component is provided, the drone charging interface component comprising a battery connection portion and a charging interface portion connected to each other;

[0008] The battery connecting portion is suitable for connecting to a drone battery;

[0009] The charging interface portion is suitable for connecting to a charging plug of a drone;

[0010] The charging interface portion has a recessed area and a plurality of interface contacts, wherein the plurality of interface contacts are located in the recessed area, and a cross section of the recessed area gradually increases in a direction gradually away from the battery connecting portion.

[0011] Optionally, the cross-section of the recessed area is a non-centrosymmetrical shape to facilitate fool-proofing.

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

[0013] Optionally, the recessed area is arranged with a magnetic attraction portion.

[0014] Optionally, the recessed area is arranged with two magnetic attraction parts, and the two magnetic attraction parts are respectively located on both sides of the multiple interface contacts.

[0015] Optionally, the battery connecting portion includes an opening portion and a snap portion, and the snap portion extends from an edge of the opening portion in a direction away from the charging interface portion.

[0016] Optionally, the multiple interface contacts 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 suitable for being connected to any of the drone charging interface components described above to charge the drone battery. The drone charging plug includes an insertion portion and a holding portion that are connected, and the insertion portion has plug contacts suitable for being connected to the multiple interface contacts. The cross-section of the insertion portion gradually decreases in a direction gradually away from the holding portion.

[0018] Optionally, a spring ejector pin is provided on an end surface of the holding portion facing away from the insertion portion, and the spring ejector pin extends from the holding portion toward the insertion portion.

[0019] On the other hand, a drone charging system is provided, which includes a drone and any of the drone charging plugs described above, the drone includes a drone battery and any of the drone charging interface components described above, the drone battery is connected to the battery connecting portion of the drone charging interface component, and the drone charging plug is suitable for docking with the charging interface portion of the drone charging interface component.

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

[0021] The charging interface of the UAV charging interface has a recessed area. In the direction away from the battery connection part, the cross section of the recessed area gradually increases, thereby increasing the side area of ​​the recessed area, so that the contact area between the recessed area and the UAV charging plug increases. In this way, the friction between the recessed area and the UAV charging plug increases, so that the charging interface is more closely connected to the UAV charging plug. The side of the recessed area also has a good guiding and limiting effect, so that the charging contacts of the UAV charging plug can be better connected with the multiple interface contacts in the recessed area, improving the problem of poor charging contact. At the same time, the increase in contact area can better disperse the force exerted by the UAV charging plug on the charging interface, thereby improving the bearing capacity of the charging interface to the force, ensuring the stability of the charging process, and improving the charging efficiency of the UAV. In addition, since the cross section of the recessed area gradually increases in the direction away from the battery connection part, when the UAV charging plug is inserted into the recessed area, the shape of the recessed area makes it unnecessary for the UAV charging plug to be precisely aligned before insertion. Therefore, this is also conducive to the use of mechanical automation to connect the UAV charging plug with the charging interface, avoiding excessive requirements on the machinery during automation, and effectively reducing the production and use costs of automated machinery.

[0027] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0028] An embodiment of the present application provides a drone charging interface component, which can reduce the problem of poor charging contact that is easily encountered in a drone charging device.

[0029] Please refer to Figure 1 The drone charging interface 10 includes a battery connecting portion 11 and a charging interface portion 12 connected to each other. The battery connecting portion 11 is suitable for connecting to a drone battery 20, and the charging interface portion 12 is suitable for connecting to a 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 a plurality of interface contacts 122, and the plurality of interface contacts 122 are 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 plurality of interface contacts 122 in the recessed area 121, thereby achieving charging.

[0031] In the direction gradually away from the battery connection portion 11, the cross section of the recessed area 121 of the charging interface portion 12 gradually increases. That is, in the direction gradually away from the battery connection portion 11, at least one side of the recessed area 121 extends in a direction gradually away from the plurality of interface contacts 122. Figure 2 The sides of the recessed area 121 away from the ground can extend 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. In this way, the side area of ​​the recessed area 121 increases, and the contact area between the recessed area 121 and the drone charging plug 30 also increases, thereby increasing the friction between the recessed area 121 and the drone charging plug 30, so that the charging interface part 12 and the drone charging plug 30 are more closely connected. The increase in the contact area between the recessed area 121 and the drone charging plug 30 can also better disperse the force exerted by the drone charging plug 30 on the charging interface part 12, further ensuring the stability of the charging process. At the same time, the shape of the recessed area 121 makes it unnecessary for the drone charging plug 30 to be precisely aligned before insertion, which is conducive to the use of mechanical automation operation to connect the drone charging plug 30 and the charging interface part 12.

[0033] In summary, the drone charging interface provided by the embodiment of the present application includes a connected battery connection part and a charging interface part. In the direction gradually away from the battery connection part, the cross-section of the recessed area of ​​the charging interface part gradually increases, thereby increasing the side area of ​​the recessed area, so that the contact area between the recessed area and the drone charging plug increases. In this way, the friction between the recessed area and the drone charging plug increases, so that the charging interface part and the drone charging plug are more closely connected. The side of the recessed area also has a good guiding and limiting effect, so that the drone charging plug can be better connected with multiple interface contacts in the recessed area, improving the problem of poor charging contact. At the same time, the increase in contact area can better disperse the force exerted by the drone charging plug on the charging interface part, thereby improving the charging interface part's ability to withstand the force, ensuring the stability of the charging process, and improving the drone charging efficiency. In addition, since the cross-section of the recessed area gradually increases in the direction away from the battery connecting part, when the drone charging plug is inserted into the recessed area, the shape of the recessed area makes it unnecessary to precisely align the drone charging plug before inserting it. Therefore, this is also conducive to the use of mechanical automation operation to connect the drone charging plug with the charging interface part, avoiding excessive requirements on the machinery during automated operation, and effectively reducing the production and use costs of automated machinery.

[0034] In the related art, the drone charging structure is prone to reverse connection. If the cross-section of the recessed area 121 of the charging interface portion 12 is a centrally symmetrical shape, then correspondingly, the cross-section of the portion where the drone charging plug 30 is coupled to the recessed area 121 is also a centrally symmetrical shape. In this way, when the drone charging plug 30 is coupled to the recessed area 121, it is easy for the drone charging plug 30 to be reversely connected. The cross-section of the recessed area 121 of the drone charging interface 10 provided in the embodiment of the present application can be a non-centrally symmetrical shape. Only when the drone charging plug 30 correctly adapts to the shape of the recessed area 121 can the coupling of the drone charging plug 30 and the recessed area 121 be achieved, thereby preventing the drone charging plug 30 from being reversely connected, so as to prevent foolishness.

[0035] Optionally, the cross section of the recessed area 121 may be a rectangle with two adjacent rounded corners, that is, the cross section of the recessed area 121 is a non-center-symmetrical shape. Accordingly, the cross section of the drone charging plug 30 also has two adjacent rounded corners. Figure 2, two adjacent rounded corners of the cross section of the recessed area 121 can be located on the side of the recessed area 121 away from the ground, and at the same time, in the direction perpendicular to the ground, the side of the recessed area 121 away from the ground can protrude from the side of the recessed area 121 close to the ground. 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, the drone charging plug 30 can correctly adapt to the shape of the recessed area 121, so that the drone charging plug 30 can be coupled with the recessed area 121 to achieve the effect of preventing reverse connection.

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

[0037] like Figure 2 As shown, the recessed area 121 of the drone charging interface 10 may be arranged with two magnetic attraction parts 123, the two magnetic attraction parts 123 may be rectangular, and are respectively located on both sides of the plurality of interface contacts 122, and the drone charging plug 30 may also be arranged with two magnetic attraction parts corresponding to the two magnetic attraction parts 123. In this way, when the drone charging plug 30 is coupled with the recessed area 121, the two magnetic attraction parts of the drone charging plug 30 may be respectively adsorbed with the two magnetic attraction parts 123 of the recessed area 121, so that the connection between the drone charging plug 30 and the drone charging interface 10 is tighter, further ensuring the stability of the drone charging process.

[0038] The battery connection part 11 of the drone charging interface 10 is connected to the drone battery 20, so that the drone battery 20 can be connected to the drone charging interface 10 to facilitate charging the drone battery 20. Figure 3The battery connection part 11 has a first surface 111 and a second surface 112 in a direction away from the charging interface part 12, wherein the first surface 111 is a surface close to the charging interface part 12, and the second surface 112 is a surface away from the charging interface part 12, wherein the second surface 112 is connected to the drone battery 20. The orthographic projection area of ​​the second surface 112 on the charging interface part 12 is smaller than the orthographic projection area of ​​the first surface 111 on the charging interface part 12, that is, there is a non-overlapping area between the orthographic projection of the first surface 111 on the charging interface part 12 and the orthographic projection of the second surface 112 on the charging interface part 12, and the non-overlapping area is distributed on the first surface 111. The battery connection part 11 may include an opening and a buckle part 113, wherein the non-overlapping area of ​​the orthographic projection distributed on the first surface 111 is the opening, and the buckle part 113 is located on the side of the battery connection part 11, and the buckle part 113 extends from the edge of the opening toward the direction away from the charging interface part 12, and the battery connection part includes at least two symmetrical buckle parts 113. There is a snap groove at a corresponding position on the drone body, so that the snap part 113 can extend into the snap groove of the drone body to achieve snap connection, thereby fixing the drone battery 20 and the drone charging interface 10 on the drone body. Of course, the snap part 113 may not extend into the snap groove, so that the drone battery 20 and the drone charging interface 10 can be removed from the drone body, and the drone battery 20 can be detached. In this way, when charging the drone, the drone battery 20 can be charged directly on the drone, or the drone battery 20 can be removed and charged separately, which allows the drone to adapt to a variety of charging environments, thereby improving the user experience.

[0039] The multiple interface contacts 122 of the drone charging interface 10 include at least two power contacts and at least two communication contacts, that is, the drone charging interface 10 includes at least four interface contacts 122. The two power contacts can be a positive contact and a negative contact. The power contacts of the drone charging interface 10 are connected to the drone charging plug 30 to charge the drone battery 20. The communication contacts of the drone charging interface 10 are connected to the drone charging plug 30 to transmit some information of the drone battery 20 to ensure the smooth charging process of the drone battery 20.

[0040] In summary, the embodiment of the present application provides a drone charging interface, the charging interface of the drone charging interface has a recessed area, and the cross section of the recessed area gradually increases in the direction away from the battery connection part, thereby increasing the side area of ​​the recessed area, so that the contact area between the recessed area and the drone charging plug is increased, and the friction between the recessed area and the drone charging plug is increased, so that the charging interface is more closely connected to the drone charging plug, and the side of the recessed area also has a good guiding and limiting effect, so that the drone charging plug can be better connected to the multiple interface contacts in the recessed area, improving the problem of poor charging contact. The increase in contact area can also better disperse the force exerted by the drone charging plug on the charging interface, thereby improving the ability of the charging interface to withstand the force and ensuring the stability of the charging process. At the same time, the shape of the recessed area makes it unnecessary for the drone charging plug to be precisely aligned before being inserted, so this is also conducive to the use of mechanical automation to connect the drone charging plug and the charging interface, avoiding excessive requirements on the machinery during the automated operation, and effectively reducing the production and use costs of the automated machinery. In addition, the cross section of the recessed area is a non-centrally symmetrical shape, so that the effect of preventing the drone charging plug from being reversely connected can be achieved. The recessed area can be provided with a magnetic attraction part, and the drone charging plug can be more tightly connected to the drone charging interface part, further ensuring the stability of the charging process. The drone charging interface part is connected to the drone battery, and the drone charging interface part has a snap part that can be inserted into the snap groove on the drone body, so that the drone battery can be detachable, so that the drone can adapt to a variety of charging environments, further improving the user experience.

[0041] Please refer to Figure 3 The embodiment of the present application also provides a drone charging plug 30, which is suitable for connecting to the drone charging interface 10 provided in the embodiment of the present application. The drone charging plug 30 includes a connected holding portion 31 and an insertion portion 32. The holding portion 31 facilitates the user or the mechanical automation structure to hold the drone charging plug 30 for insertion or removal, and the insertion portion 32 facilitates connection with the drone charging interface 10. When the drone charging plug 30 is inserted into the drone charging interface 10, the insertion portion 32 extends into the recessed area 121, and the holding portion 31 is located outside the recessed area 121, which is convenient for being held or connected to other mechanical components.

[0042] The insertion portion 32 has a plurality of plug contacts 321, and the plurality of plug contacts 321 correspond to the plurality of 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 with the recessed area 121 of the drone charging interface 10, and at the same time, the plurality of plug contacts 321 of the insertion portion 32 are electrically connected with the plurality of interface contacts 122 of the recessed area 121 in a one-to-one correspondence.

[0043] Among them, the multiple plug contacts 321 of the drone charging plug 30 include at least two power contacts and at least two communication contacts, that is, the drone charging plug 30 includes at least four plug contacts 321. The two power contacts can be a positive contact and a negative contact. The power contacts of the drone charging plug 30 are connected to the power contacts of the drone charging interface 10 to charge 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 to transmit some information of the drone battery 20 to ensure the smooth charging process of the drone battery 20.

[0044] In the drone charging plug 30 provided in the embodiment of the present application, the cross section of the insertion portion 32 gradually decreases in the direction gradually away from the grip portion 31. That is, in the direction gradually away from the grip portion 31, at least one side of the insertion portion 32 extends in the direction gradually approaching the plurality of plug contacts 321, thereby increasing the side area of ​​the insertion portion 32. Figure 3 As shown, the side of the insertion portion 32 away from the ground can extend in the direction close to the multiple plug contacts 321, and the side of the insertion portion 32 close to the ground can be a plane, and the side of the recessed area 121 of the drone charging interface 10 away from the ground can extend in the direction away from the multiple interface contacts 122, and protrude from the side of the recessed area 121 close to the ground. In this way, 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 is coupled with the recessed area 121 of the drone charging interface 10, please refer to Figure 1 , the insertion portion 32 may partially enter the recessed area 121 , and a side of the insertion portion 32 close to the ground may not enter the recessed area 121 .

[0045] Since the side area of ​​the insertion portion 32 is increased, and the insertion portion 32 can adapt to the shape of the recessed area 121 of the drone charging interface 10, the contact area between the insertion portion 32 and the recessed area 121 of the drone charging interface 10 is also increased, thereby increasing the friction between the insertion portion 32 and the recessed area 121, so that the drone charging plug 30 and the drone charging interface 10 are more tightly connected. At the same time, the increase in 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 the force, ensuring the stability of the charging process, and improving the drone charging efficiency.

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

[0047] In order to be suitable for connection with the drone charging interface 10 provided in the embodiment of the present application, the drone charging plug 30 may have a magnetic attraction portion. Figure 3 The insertion portion 32 of the drone charging plug 30 may be provided with two magnetic attraction portions 322, which may be rectangular and respectively located on both sides of the plurality of plug contacts 321. In this way, when the insertion portion 32 of the drone charging plug 30 is coupled with the recessed area 121 of the drone charging interface 10, the two magnetic attraction portions 322 of the insertion portion 32 may be respectively adsorbed with the two magnetic attraction 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 portion 32 of the drone charging plug 30 can partially enter the recessed area 121 of the drone charging interface 10, thereby achieving coupling. The grip portion 31 of the drone charging plug 30 does not enter the recessed area 121, and the user can insert the drone charging plug 30 into the drone charging interface 10 by holding the grip portion 31, or pull the drone charging plug 30 out of the drone charging interface 10. However, due to the coupling structure formed by the insertion portion 32 and the recessed area 121, and the mutual adsorption of the two magnetic suction portions 322 of the insertion portion 32 and the two magnetic suction portions 123 of the recessed area 121, the connection between the insertion portion 32 and the recessed area 121 is relatively tight, and it is not easy for the user to pull out the drone charging plug 30 from the drone charging interface 10 after charging is completed.

[0049] In this case, the drone charging plug 30 provided in the embodiment of the present application has a press-rebound structure, so that the user or related machinery can pull out the drone charging plug 30 from the drone charging interface 10. Please refer to Figure 2 The gripping portion 31 of the drone charging plug 30 is provided with a spring pin 33 on the end surface facing away from the insertion portion 32, and the spring pin 33 extends from the gripping portion 31 to the insertion portion 32. The end surface of the gripping portion 31 facing away from the insertion portion 32 may have a blind hole, and the spring pin 33 is inserted into the blind hole. Figure 4 As shown, the spring ejector 33 may include an ejector 331, a spring 332 and a housing 333, wherein the spring 332 is located in the housing 333, a portion of the ejector 331 is connected to the spring 332 in the housing 333, and 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 portion 31, at which time the ejector 331 is not subjected to force, and the spring 332 is in a relaxed state in the housing 333. After charging is completed, the user presses the end face of the holding portion 31 away from the insertion portion 32, and the ejector pin 331 is subjected to a force, and the spring 332 connected to the ejector pin 331 is compressed in a direction gradually approaching the insertion portion 32, so that the spring 332 has a stress in a direction gradually away from the insertion portion 32. At this time, the end face is stopped from being pressed, and the stress of the spring 332 causes the spring 332 to drive the ejector pin 331 to move in a direction gradually away from the insertion portion 32, thereby popping out the drone charging plug 30 from the drone charging interface 10, making it convenient for the user to remove it and improving the user experience.

[0050] In summary, the embodiment of the present application provides a drone charging plug, which includes a connected holding portion and an insertion portion. The cross-section of the insertion portion gradually decreases in the direction away from the holding portion, thereby increasing the side area of ​​the insertion portion, and the insertion portion can adapt to the shape of the recessed area of ​​the drone charging interface, and the contact area between the insertion portion and the recessed area increases accordingly, thereby increasing the friction between the insertion portion and the recessed area, so that the drone charging plug and the drone charging interface are more closely connected, improving the problem of poor charging contact. The increase in contact area can also better disperse the force exerted by the drone charging plug on the drone charging interface, thereby improving the drone charging interface's ability to withstand the force, ensuring the stability of the charging process, and improving the drone charging efficiency. At the same time, the cross-section of the insertion portion is a non-centrally symmetrical shape, so that the effect of preventing the drone charging plug from being reversed can be achieved. The insertion portion can be arranged with a magnetic suction portion corresponding to the drone charging interface, and the drone charging plug can be more tightly connected to 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 portion of the drone charging plug facing away from the insertion portion. When charging is completed, the user presses the pin, and the drone charging plug moves in a direction away from the insertion portion under the stress of the spring, thereby popping the drone charging plug out of the drone charging interface, making it easier for the user to pull it out, thereby improving the user experience.

[0051] The embodiment of the present application also provides a drone charging system, which may include a drone and any of the drone charging plugs 30 described above, and the drone may include a drone battery 20 and any of the drone charging interface components 10 described above. The drone charging interface component 10 includes a battery connection portion 11 and a charging interface portion 12 connected to each other, and the drone battery 20 may be connected to the battery connection portion 11 of the drone charging interface component 10, and the battery connection portion 11 has a snap portion 113, and the drone fuselage has a snap groove, and the snap portion 113 may extend into the snap groove on the drone fuselage, so that the drone battery 20 and the drone charging interface component 10 can be fixed on the drone fuselage. Of course, the snap portion 113 may not extend into the snap groove on the drone fuselage, so that the drone battery 20 can be removed from the drone fuselage. The design of the snap portion 113 and the snap groove enables the drone battery 20 to be detachable, so that when the drone user charges the drone battery 20, he can charge it directly on the drone, or he can remove the drone battery 20 and charge the battery separately, so that it can adapt to a variety of charging environments and improve the user experience.

[0052] When charging the drone, the drone charging plug 30 is suitable for docking with the charging interface part 12 of the drone charging interface part 10. The drone charging plug 30 includes a connected holding part 31 and an insertion part 32, the insertion part 32 has a plurality of plug contacts 321, and the charging interface part 12 of the drone charging interface part 10 has a plurality of interface contacts 122. When charging, the plurality of plug contacts 321 of the drone charging plug 30 are electrically connected with the plurality of interface contacts 122 of the drone charging interface part 10 in a one-to-one correspondence, and the drone charging plug 30 is connected to the power source, so as to charge the drone.
