Figure 1 The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0047] With the continuous progress of electronic technology, the development of unmanned aerial vehicle battery chargers is provided with technical support, and the requirements of users for convenience and safety are improved. When using the unmanned aerial vehicle, the user hopes that the charger is simple to operate, convenient to carry, and can ensure the safety and reliability of the charging process.

[0048] The existing unmanned aerial vehicle battery charger cannot charge multiple batteries when charging the battery, and is prone to overheating during the charging process, which reduces the charging current and affects the charging efficiency of the unmanned aerial vehicle battery charger.

[0049] ​To this end, the present inventors provide a UAV battery charger and charging system, aiming to solve the problem that the existing UAV battery charger cannot charge multiple batteries at the same time and is prone to overheating during charging, resulting in reduced charging efficiency.

[0050] The UAV battery charger of the present technical solution can not only charge multiple UAV batteries, but also transfer power from an external power supply to the UAV batteries after connecting the external power supply, to achieve battery charging.

[0051] In detail, as shown in Figure 1 , Figure 2 and Figure 5 , the overall shape of the UAV battery charger of the present technical solution is a cuboid, which has a shell 1, preferably made of insulating material such as plastic. The shell 1 has an upper shell 12 and a base 11, the upper shell 12 has an assembly cavity 121; when the upper shell 12 is closed on the base 11, the assembly cavity 121 cooperates with the base 11 to form an assembly area 13; the assembly area 13 is assembled with a circuit board 2 and a heat sink 3. Further, the upper shell 12 has an air inlet 5 and a ventilation hole 123, the air inlet 5 is used to flow external gas into the shell 1; the ventilation hole 123 is arranged on the side close to the heat sink 3, the ventilation hole 123 is used to discharge the heat generated by the heat sink 3 to the outside of the shell 1.

[0052] Among them, the heat sink 3 is directed towards at least part of the circuit board 2, used to dissipate heat from the electronic components of the circuit board 2, to avoid the temperature of the electronic components on the circuit board 2 from being too high when working.

[0053] The circuit board 2 has various circuits on it, each circuit is connected with a functional component to ensure the normal function of the UAV battery charger.

[0054] Specifically, as shown in Figure 3 , the circuit board 2 has a control circuit 21, the control circuit 21 is connected with at least one power output branch 211; each power output branch 211 is connected with an output interface 2111; in use, a UAV battery charging seat is connected to the UAV battery charger through a connecting line, the charging seat obtains power from the UAV battery charger through the line, thereby achieving battery charging. In this embodiment, as shown in Figure 2 , the output interface 2111 has multiple and is arranged side by side on one side of the shell 1, which can charge multiple charging seats at the same time to charge multiple UAV batteries.

[0055] The unmanned aerial vehicle battery charging seat adopts the following charging mode when charging the unmanned aerial vehicle battery, which is completed by the control circuit 21, and the basic mode of the specific charging mode is to obtain the power state data of each battery to be charged connected with the power output branch, and then sort the power state data of each battery to be charged; finally, the battery is charged based on the hierarchical sorting.

[0056] That is, the present scheme first obtains the power state data of each battery to be charged, then sequentially sorts, and finally charges according to the hierarchical sorting. In this way, different charging can be realized for different batteries to be charged according to the power state data of different batteries, non-uniform power charging is realized, and the effect of charging according to the battery state is realized. Specifically, the control circuit 21 described in the present application can be realized by using existing circuits, so it should not be considered that the control circuit 21 of the present application is not fully disclosed.

[0057] In the charging mode, the lowest remaining power is used as the charging priority, that is, after obtaining the power state data of each battery to be charged, then sequentially sorting, and finally charging the battery with the lowest power through the output interface 2111. Of course, the above charging method is prior art, and only a basic description is made in the present embodiment, so it should not be considered that the present charging method is not fully disclosed, and it should not be considered that the scheme of the present application is based on the charging method and does not meet the requirements of the utility model protection customer.

[0058] In one embodiment of the present application, as shown in Figure 3 The control circuit 21 is electrically connected to a power input branch 212, and the power input branch 212 is connected to an input interface 2121 for external power supply; the input interface 2121 is electrically connected to the circuit board 2 placed inside the shell 1, and is controlled by the control circuit 21. Through the electrical connection of the input interface 2121, the external power supply can be connected to the unmanned aerial vehicle battery charger to realize power supply, thereby ensuring that the unmanned aerial vehicle battery charger can continuously supply power to the battery.

[0059] It should be noted that the output interface 2111 and the input interface 2121 are respectively exposed on the two sides of the shell 1; that is, as shown in Figure 2 The output interface 2111 and the input interface 2121 are respectively exposed on the end surface of the width of the length direction of the shell 1. This design is convenient for users to connect the battery charging.

[0060] In one embodiment of the present application, as shown in Figure 3As shown, the control circuit 21 is electrically connected with a system power switching branch 213; the other end of the system power switching branch 213 is connected with a TYPE C interface 2131; the system power switching branch 213 is electrically connected with the control circuit 21 to realize input of power to the unmanned aerial vehicle battery charger and / or to realize output of power of the unmanned aerial vehicle battery charger to external equipment when plugged with an external power supply. In the embodiment, the TYPE C interface 2131 is located near the side of the output interface 2111, and part of the TYPE C interface 2131 is exposed on the end surface of the shell 1.

[0061] Compared with the conventional unmanned aerial vehicle battery charging device, the utility model has a system power switching branch 213, which can be used to connect with external electronic equipment to realize charging of the equipment, and increase compatibility; on the other hand, the system power switching branch 213 can also realize input of power to the charger when plugged with an external power supply. That is, the system power switching branch 213 can realize charging of electronic equipment (remote controller, mobile phone, etc.), and also can realize power supply to the entire unmanned aerial vehicle battery charger as a plug-in interface of an external power supply. In this way, the system power switching branch 213 can be compatible with many electronic equipment and plugged with a conventional TYPE C interface power line, which facilitates the user to use and reduces the number of adapters for carrying.

[0062] In an embodiment of the utility model, the control circuit 21 is electrically connected with a display branch 214, and the other end of the display branch 214 is electrically connected with the display 4; the display 4 is electrically connected with the control circuit 21, so that the control circuit 21 transmits display data to the display 4 to facilitate the user to understand the battery state corresponding to the minimum power. It should be understood that the battery power number displayed by the display 4 corresponds to the number of batteries to be charged, and there is a corresponding power bar to display the power of the corresponding battery.

[0063] Further, as shown in the drawings, Figure 1 The display 4 is located near the end of the power output branch 211, and at least part of the display 4 is exposed on the surface of the shell 1 to facilitate the user to intuitively observe the power of the battery to be charged.

[0064] When the unmanned aerial vehicle battery charger works, the components on the circuit board 2 are easy to generate heat, thereby affecting the charging efficiency of the unmanned aerial vehicle battery charger.

[0065] For this purpose, in an embodiment of the utility model, as shown in the drawings, Figure 1 , Figure 4 and Figure 5As shown, the housing 1 has the heat sink 3 inside near the end of the input interface 2121; the heat sink 3 is used to dissipate heat for the circuit board 2, preferably the heat sink 3 is arranged near the end of the input interface 2121, since the input interface 2121 is connected to an external power supply, the current at this place is usually larger, and it is easier to generate heat, therefore, the heat sink 3 is preferably arranged near the end of the input interface 2121.

[0066] In another embodiment, the heat sink 3 is arranged near the top of the end of the input interface 2121, that is, the bottom of the heat sink 3 is 1-5 cm away from the circuit board 2. In this way, an air flow channel is formed between the circuit board 2 and the heat sink 3, which helps the heat generated by all electronic components on the circuit board 2 to flow to the heat sink 3, and then be sucked out by the heat sink 3.

[0067] In detail, as shown in Figure 4 and Figure 5 The heat sink 3 includes a fan cover 31 and a fan body 32; the fan cover 31 has a hollow assembly part 311 for assembling the fan body 32; the heat sink 3 has a suction part 33 and an air outlet part 34; when the fan body 32 rotates, the suction part 33, the air outlet part 34 and the ventilation hole 123 in the upper shell 12 form an air flow channel 35 for transmitting air flow outside the housing 1. The suction part 33 faces the circuit board 2, and the air outlet part 34 faces the ventilation hole 123.

[0068] It should be noted that the fan cover 31 is assembled on the inside of the top of the housing 1 by screws, and one side of the fan cover 31 facing the circuit board 2 has a lower opening as shown by the double-headed arrow, the suction part 33 is exposed from the lower opening and faces the circuit board 2. One side of the fan cover 31 facing the ventilation hole 123 has a side opening, and the air outlet part 34 is exposed from the side opening and faces the ventilation hole 123. Figure 5

[0069] ​The fan body 32 is connected with the circuit board 2 and can rotate under the control of the control circuit 21. When the fan body 32 rotates, one end of the fan body 32 forms a negative pressure area, so that the airflow inside the shell 1 flows to the negative pressure area, and then the external airflow enters the negative pressure area from the air inlet 5. Since the movement path of the airflow is along the length direction of the circuit board 2, the heat generated by the electronic components on the circuit board 2 can be brought to the negative pressure area, and the heat airflow enters the airflow channel 35 under the suction of the suction part 33, and then reaches the air outlet part 34 along the airflow channel 35. Since the air outlet part 34 is directed to the ventilation hole 123, the airflow can flow out of the air outlet part 34 from the ventilation hole 123 to the outside, thereby playing a role in heat dissipation for the electronic components on the circuit board 2.

[0070] Further, the base 11 is provided with a buckle 14; the buckle 14 is arranged towards the inner wall 122 of the upper shell 12; when the upper shell 12 is covered on the base 11, the buckle 14 fixes the inner wall 122 of the upper shell 12.

[0071] It should be understood that such design facilitates the disassembly and assembly of the upper shell 12 and the base 11, so that the unmanned aerial vehicle battery charger can be maintained when necessary.

[0072] In addition, as shown in the accompanying drawings, Figure 6 It is proposed that a charging system 100 includes the unmanned aerial vehicle battery charger 101 described above, which is used to charge the battery 102.

[0073] In this embodiment, the battery 102 is electrically connected with the unmanned aerial vehicle battery charger 101 through a power line, so as to realize the charging of the battery 102 by obtaining the power on the unmanned aerial vehicle battery charger 101.

[0074] In another use scenario, the battery 102 has a plurality of, when each charging seat 103 is respectively electrically connected with the unmanned aerial vehicle battery charger 101 through a power line, at this time, the unmanned aerial vehicle battery charger simultaneously charges a plurality of batteries 102.

[0075] In summary, the unmanned aerial vehicle battery charger of the technical solution can effectively solve the problem that the existing unmanned aerial vehicle battery charger cannot simultaneously charge multiple batteries and is prone to overheating during charging, resulting in reduced charging efficiency.

[0076] According to the disclosure and teaching of the above description, the skilled in the art of the present application can also change and modify the above embodiments. Therefore, the present application is not limited to the specific embodiments disclosed and described above, and some modifications and changes of the present application should also fall within the protection scope of the claims of the present application. In addition, although some specific terms are used in the specification, these terms are only for convenience of description and do not constitute any limitation on the present application.
