Description

TECHNICAL FIELD

[0001] The utility model relates to unmanned aerial vehicle charging equipment technical field especially unmanned aerial vehicle charger and unmanned aerial vehicle charging system. BACKGROUND

[0002] Before the rise of unmanned aerial vehicle technology, the charging equipment is mainly aimed at traditional electronic products, such as mobile phones, notebook computers, etc.

[0003] With the wide application of unmanned aerial vehicles in various fields, including aerial photography, agricultural plant protection, logistics distribution, etc., the performance requirements of unmanned aerial vehicle chargers are also getting higher and higher. In the field of aerial photography, photographers may need to complete multiple flight shooting tasks in a short time. If the charging time is too long, many shooting opportunities will be missed.

[0004] In order to meet the needs of unmanned aerial vehicle charging, charger manufacturers began to integrate smart chip technology into charger design. These smart chips can monitor the temperature, voltage, current and other parameters of the battery, automatically adjust the charging current and voltage according to the charging state of the battery, and also can realize charging multiple batteries at the same time.

[0005] However, the existing unmanned aerial vehicle battery charger usually directly allocates power equally to each battery to be charged, which cannot realize intelligent allocation according to the status of different batteries, resulting in too long overall charging time. For example, the charger and battery of DJI mavic3, the charging power of the charger is 200W, the charging position of the charger is three, and when charging, one battery is plugged into each charging position, and each battery is allocated 200 / 3W of power. However, the maximum rated power of each battery is 100W, and the charging power allocated to each battery is 200 / 3W. Therefore, during charging, since the storage of each battery is different, the actual charging power required by each battery is different, so each battery cannot be charged with appropriate power, resulting in a long waiting time for the user and cannot meet the user's demand for faster use of the battery.

[0006] Therefore, the above technical problems need to be solved. UTILITY MODEL CONTENT

[0034] The following will be combined with the drawings Figure 1 to the drawings Figure 2The technical solutions in the embodiments of the present application are clearly and completely described, and obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0035] As the unmanned aerial vehicle is widely used in various fields, and the unmanned aerial vehicle usually works with a lithium battery, the lithium battery needs to be charged. However, when the unmanned aerial vehicle charger is connected to an external power supply, the unmanned aerial vehicle charger cannot adjust the charging power suitable for the current charging circuit according to the different external power supply connected. In the prior art, different chargers are usually matched with different external power supplies to obtain suitable impulse power, which brings great difficulty to the user of the unmanned aerial vehicle, and many chargers need to be carried when going out for work, which is very inconvenient.

[0036] To this end, the present application provides an unmanned aerial vehicle charger, which aims to solve the problem that the existing unmanned aerial vehicle charger cannot match the appropriate charging power according to the current charging information of the battery to be charged.

[0037] As shown in detail in Figure 1 The present technical solution is an unmanned aerial vehicle charger for charging the battery of the unmanned aerial vehicle, which can simultaneously charge multiple unmanned aerial vehicle batteries. It comprises a shell, a power manager 1, an input power circuit 2, a charging circuit 3, a battery switching circuit 3 and a battery communication circuit 5, and a charging interface 7 in the shell. The first end of the input power circuit 2 is electrically connected to the power manager 1, and the other end of the input power circuit 2 is electrically connected to an external power supply for obtaining the power information of the external power supply and transmitting it to the power manager 1. It should be understood that in the present embodiment, the external power supply includes a mobile power supply or other devices capable of providing power. When the present unmanned aerial vehicle charger is connected to the external power supply, the power of the external power supply flows through the unmanned aerial vehicle charger to the battery of the unmanned aerial vehicle, thereby realizing the charging of the battery of the unmanned aerial vehicle.

[0038] Specifically, when the present unmanned aerial vehicle charger is connected to the external power supply, the power supply of different models of external power supply is inconsistent, the charging power of the external power supply is transmitted through the input power circuit 2, the input power circuit 2 transmits the received charging power information to the power manager 1, and the power manager 1 calculates the charging power suitable for the current charging circuit according to the received charging power information.

[0039] Further, the power manager 1 comprises a power distribution circuit 9; an input end of the power distribution circuit 9 is electrically connected with the input power circuit 2, and a control end of the power distribution circuit 2 is electrically connected with the power manager 1; and an output end of the power distribution circuit 9 is electrically connected with the charging circuit 3.

[0040] For example, the charging power of the external power supply is 300W, the unmanned aerial vehicle charger of the present technical solution is currently connected with three unmanned aerial vehicle batteries which need to be charged, and the battery inventories of the three unmanned aerial vehicle batteries are different, so the voltages and the charging capacities of the three unmanned aerial vehicle batteries are different. In order to connect multiple batteries, the most appropriate charging power can be output for the current battery according to the current battery charging information. At this time, the power distribution circuit 9 outputs the charging power information suitable for the current charging circuit 3 to the power manager 1 for processing and analysis after receiving the charging power information of the current external power supply transmitted by the input power circuit 2. The power manager 1 outputs the maximum charging power which can adapt to the current charging circuit 3, so that the current unmanned aerial vehicle charging battery can be effectively and quickly charged, thereby overcoming the problem that the rated maximum power of each battery is 1 / n of the external charging power in the prior art. In this way, each battery cannot reach the maximum power for charging during charging, which leads to a long waiting time for the user and cannot meet the user's demand for faster use of the battery.

[0041] Further, a first end of the battery communication circuit 5 is electrically connected with the power manager 1, and a second end of the battery communication circuit 5 is electrically connected with the charging interface 7, so as to obtain the battery information of the unmanned aerial vehicle battery to be charged and transmit the battery information to the power manager 1 when the charging interface 7 is plugged with the unmanned aerial vehicle battery to be charged.

[0042] It should be noted that the charging interface 7 is used to turn on the charging path between the battery and the unmanned aerial vehicle charger, and the charging interface 7 is located at one end of the battery to be charged.

[0043] When the unmanned aerial vehicle battery to be charged is connected with the unmanned aerial vehicle charger, the battery communication circuit 5 and the unmanned aerial vehicle battery to be charged are connected through the charging interface 7 to obtain the charging information of the unmanned aerial vehicle battery to be charged, and then the charging information is transmitted to the power manager 1. The power manager 1 controls the charging circuit 3 to output the appropriate charging voltage based on the received charging information of the battery to be charged.

[0044] In detail, one end of the charging circuit 3 is connected with the power manager 1, and the other end of the charging circuit 3 is electrically connected with the charging interface, so as to control the charging of the unmanned aerial vehicle battery to be charged based on the control information transmitted by the power manager 1 based on the battery information.

[0045] In summary, the unmanned aerial vehicle charger can output the maximum charging power in the charging circuit 3 according to the charging power input by the external power source and the charging information of the unmanned aerial vehicle battery to be charged, and the power manager 1 outputs the appropriate charging voltage information to the charging circuit 3, so as to realize the charging of the unmanned aerial vehicle battery to be charged by the charging circuit 3.

[0046] In another embodiment, the charging circuit 3 has multiple paths, and each path of the charging circuit 3 is connected to one charging interface 7.

[0047] It should be understood that, as designed, the unmanned aerial vehicle charger of the embodiment can charge multiple unmanned aerial vehicle batteries at the same time, and the connection of each path of the unmanned aerial vehicle battery to be charged to the power manager 1 is in parallel, which enables the power manager 1 to match the most appropriate charging voltage for each path of the unmanned aerial vehicle battery to be charged, and each path of the battery does not interfere with each other when charging, effectively improving the charging efficiency when charging different models of batteries.

[0048] In another embodiment, each path of the charging circuit 3 is connected to a switching circuit 4; the input end of the switching circuit 4 is connected to the charging circuit 3, the output end of the switching circuit 4 is connected to the charging interface 7, and the control end of the switching circuit 4 is electrically connected to the power manager 1.

[0049] It should be understood that the switching circuit 4 is used to control the charging priority of the multiple paths of the charging circuit 3 connected at present, that is, when A battery needs to be charged first, the switching circuit 4 corresponding to A battery is turned on, so that the power manager 1 charges A battery first.

[0050] Preferably, the switching circuit 4 is a switching controller. In some other embodiments, the switching circuit 4 is connected with a signal indicator in the power manager 1, and the charging circuit of the battery to be charged first is turned on through the two ways.

[0051] In another embodiment, a logic control circuit 8 can be used to sort the charging circuits to be charged at present and control the charging priority.

[0052] In detail, an input end of the logic control circuit 8 is electrically connected with the battery communication circuit 5, and another end of the logic control circuit 8 is electrically connected with the power manager 1; the logic control circuit 8 is used for determining output charging priority information or power-off priority information to each of the switch circuits 4 according to the charging information provided by the battery communication circuit 5, so as to make each of the switch circuits 4 turn on or turn off the channel between each of the charging circuits 3 and the corresponding charging interface 7.

[0053] For example, in the application scenario of charging, the charging priority information includes the arrangement from low to high according to the voltage of the unmanned aerial vehicle battery to be charged.

[0054] Specifically, as shown in FIG. 1, when multiple unmanned aerial vehicle batteries need to be charged, the battery communication circuit 5 is connected with each of the unmanned aerial vehicle batteries A, B and C to be charged, so as to obtain the current power and voltage information of each unmanned aerial vehicle battery, that is, the charging information. Figure 1 The battery communication circuit 5 transmits the charging information of each unmanned aerial vehicle battery to the logic control circuit 8, the logic control circuit 8 arranges each charging information according to the voltage from low to high, such as A

[0055] When the power of the battery A approaches or exceeds the power of the battery B, the power distribution circuit 9 controls and adjusts the total charging power on the trunk line between the battery A and the battery B to realize the reduction of the charging voltage of the battery A and the priority charging of the battery B, that is, at this time, the charging circuit corresponding to the battery B is integrated into the charging circuit of the battery A for charging, the battery C is in a state of waiting to be charged, and the battery A is continuously charged at the adjusted voltage.

[0056] When the power of the battery A and the battery B approaches or exceeds the power of the battery C, the power distribution circuit 9 controls and adjusts the total charging power on the trunk line among the battery A, the battery B and the battery C to realize the reduction of the charging voltage of the battery A and the battery B, and the priority charging of the battery C, and the battery A and the battery B are continuously charged at the adjusted charging voltage. In summary, such design realizes the output of charging power suitable for battery charging according to different battery information conditions.

[0057] When the charging voltage of each of the battery A, the battery B and the battery C reaches the full charging voltage thereof, further, the power-off priority information includes an arrangement from high to low according to the full charging voltage of the unmanned aerial vehicle battery to be charged.

[0058] It should be understood that, for example, the battery A, the battery B and the battery C are arranged in the order of full charging voltage X(A)>Y(B)>Z(C), then in this embodiment, the full charging voltage of the battery C is the lowest, that is, the battery C is the first to be fully charged. Then, since the battery communication circuit 5 is connected with each unmanned aerial vehicle battery to be charged, the charging information of each battery is transmitted to the logic control circuit 8 through the battery communication circuit 5, and the logic control circuit 8 transmits the full charging voltage information received to the power manager 1, and the power manager 1 controls the corresponding switch circuit C of the battery C to be closed, so as to remove the battery C from the current charging circuit 3, so as to realize charging the remaining battery A and the battery B with the charging power on the current charging circuit 3, and so on. When the voltage of any one of the battery A or the battery B reaches the full charging voltage, the power manager 1 controls the corresponding switch circuit 4 of the battery A or the battery B to be closed, and gradually removes the fully charged battery from the current charging circuit 3. In this way, the charging efficiency of the battery can be improved, so as to ensure that the current charging circuit has the maximum charging power.

[0059] Further, the display circuit 10 is further included; the input end of the display circuit 10 is electrically connected with the power manager 1, and the display circuit 10 is used for displaying the charging state of each unmanned aerial vehicle battery.

[0060] In addition, a kind of unmanned aerial vehicle charging system is proposed, as shown in Figure 2 The unmanned aerial vehicle charger 100 described above is included;Further, a plurality of batteries 200 are included, and a plurality of the battery 200 is electrically connected with the unmanned aerial vehicle charger 100.

[0061] It can be understood that, by using the unmanned aerial vehicle charging system, the unmanned aerial vehicle battery can be fully charged at the fastest speed to meet the power demand of the unmanned aerial vehicle battery.

[0062] In summary, the unmanned aerial vehicle charger of the technical solution can not only match the appropriate charging power for the current charging circuit 3 needing to be charged by external power supply, but also output appropriate charging voltage according to the charging information of different batteries, so as to realize fast charging of the unmanned aerial vehicle battery.
