Technical Field

[0001] This utility model relates to the field of emergency power supply, and in particular to a charging box, a charging box assembly, and a drone system. Background Technology

[0002] The charging case components used in drone systems typically include a charging case, a payload (such as a remote controller), and a battery. When the charging case is connected to mains power, the battery and / or payload can be mounted on the charging case to obtain power. However, drones are generally used in outdoor environments, and if there is a lack of mains power and the payload happens to be out of power, the drone will become unusable. Utility Model Content

[0003] Therefore, it is necessary to provide a charging box, charging box components, and drone system to address the problem that drones cannot be used normally when the load power is exhausted and there is no mains power supply in the field environment.

[0004] A charging box includes a box body, on which a first electrical connector, a second electrical connector and a third electrical connector are provided;

[0005] The first electrical connector is used for electrical connection to mains power;

[0006] The second electrical connector is used for electrical connection to the battery and is electrically connected to the first electrical connector to allow the mains power to charge the battery through the housing;

[0007] The third electrical connector is used for electrical connection to the load. The third electrical connector is electrically connected to the second electrical connector to allow the battery to power the load through the housing. The first electrical connector is electrically connected to the third electrical connector to allow the mains power to power the load through the housing.

[0008] In one embodiment, a BUCK circuit is provided between the second electrical connector and the third electrical connector, a first switching power supply is provided between the first electrical connector and the second electrical connector, and a second switching power supply is provided between the first electrical connector and the third electrical connector.

[0009] In one embodiment, the housing is provided with a main control board, a first detection module, and a first switch module;

[0010] The first electrical connector, the second switching power supply, and the main control board are electrically connected in sequence. The first detection module is used to detect the electrical connection status between the first electrical connector and the mains power and is electrically connected to the main control board.

[0011] The first switch module is disposed between the second electrical connector and the BUCK circuit, and the first switch module is also electrically connected to the main control board.

[0012] In one embodiment, a second detection module is provided on the housing, and the first switch module, the BUCK circuit and the main control board are electrically connected in sequence. The second detection module is used to detect the electrical connection status of the second electrical connector and the battery and is electrically connected to the main control board.

[0013] In one embodiment, a second switch module is provided on the housing, the second switch module is located between the first switching power supply and the second electrical connector, and the second switch module is electrically connected to the main control board.

[0014] In one embodiment, the housing is provided with a fourth electrical connector for electrically connecting to the battery. The fourth electrical connector and the second electrical connector are connected in parallel to the second switch module to allow the mains power to charge the battery through the housing.

[0015] In one embodiment, a third switch module is provided on the housing, the third switch module is disposed between the BUCK circuit and the second switching power supply, and the third switch module is also electrically connected to the main control board.

[0016] A charging case assembly includes the charging case, a battery, and a load;

[0017] The battery has at least a first power supply state. When the battery is in the first power supply state, the battery is mounted on the housing and electrically connected to the second electrical connector, and the load is electrically connected to the third electrical connector.

[0018] A drone system includes a drone and the aforementioned charging box assembly, wherein the battery has at least a second power supply state, and when the battery is in the second power supply state, the battery is mounted on the drone.

[0019] In one embodiment, the number of batteries is at least two, with some of the batteries in a first powered state to enable the load to be wirelessly connected to the drone, and some of the batteries in a second powered state.

[0020] The beneficial effects of this utility model are as follows:

[0021] The first electrical connector is electrically connected to the second electrical connector. When the first electrical connector is electrically connected to AC power and the battery is electrically connected to the second electrical connector, AC power can charge the battery through both connectors. The third electrical connector is electrically connected to the first electrical connector. When the first electrical connector is electrically connected to AC power and the load is electrically connected to the third electrical connector, AC power can supply power to the load through both connectors. This ensures that AC power can charge the battery and supply power to the load.

[0022] The second electrical connector is electrically connected to the third electrical connector. When the remaining power in the load is insufficient and the first electrical connector cannot be connected to the mains power, the battery is electrically connected to the second electrical connector, and the load is simultaneously electrically connected to the third electrical connector. The battery can replace the mains power as an emergency power source. The battery provides emergency power to the load through the second and third electrical connectors, ensuring the normal use of the load. Attached Figure Description

[0034] Example:

[0035] This embodiment provides a drone system, including a drone 400 and a charging box assembly. Specifically, the charging box assembly includes a charging box, a battery 200, and a payload 300.

[0036] The battery 200 has at least a charging state and a second power supply state. When the battery 200 is in the charging state, the charging box is electrically connected to the mains power 100, the battery 200 is placed on the charging box, and the mains power 100 charges the battery 200 through the charging box. When the battery 200 is in the second power supply state, the battery 200 is installed on the drone 400 to supply power to the drone 400.

[0037] Typically, there are at least two batteries 200, to allow some batteries 200 to be in a charging state and others to be in a secondary power supply state. For example... Figure 1 and Figure 2 As shown, the charging box includes a box body 1, on which a battery slot 114 is provided. The battery slot 114 is used to hold batteries 200, so the number of battery slots 114 is generally not less than the number of batteries 200.

[0038] Payload 300 is usually a remote controller, which can wirelessly control the drone 400 during flight.

[0039] like Figure 3 As shown, the housing 1 is provided with a first electrical connector 11, a second electrical connector 12, and a third electrical connector 13. The first electrical connector 11, the second electrical connector 12, and the third electrical connector 13 can be conductive metal sheets, coupling connectors, or other forms of electrical connectors. This embodiment does not limit the specific forms of the first electrical connector 11, the second electrical connector 12, and the third electrical connector 13.

[0040] The first electrical connector 11 is used to electrically connect to the mains power 100, the second electrical connector 12 is used to electrically connect to the battery 200, and therefore at least part of the battery compartment 114 is provided with the second electrical connector 12, and the third electrical connector 13 is used to electrically connect to the load 300.

[0041] In this embodiment, the first electrical connector 11 can be electrically connected to the second electrical connector 12 without going through the third electrical connector 13, the second electrical connector 12 can be electrically connected to the third electrical connector 13 without going through the first electrical connector 11, and the third electrical connector 13 can be electrically connected to the first electrical connector 11 without going through the second electrical connector 12.

[0042] When the first electrical connector 11 is electrically connected to the mains power 100 and the battery 200 is electrically connected to the second electrical connector 12, the mains power 100 can charge the battery 200 through the first electrical connector 11 and the second electrical connector 12.

[0043] Since the mains power 100 provides alternating current and its effective voltage is higher than the charging voltage of the battery 200, it is preferable that a first switching power supply 15 be provided between the first electrical connector 11 and the second electrical connector 12 in this embodiment, so as to step down the voltage between the mains power 100 and the battery 200.

[0044] When the first electrical connector 11 is electrically connected to the mains power 100 and the load 300 is electrically connected to the third electrical connector 13, the mains power 100 can supply power to the load 300 through the first electrical connector 11 and the third electrical connector 13, allowing the load 300 to operate normally. After receiving power, the load 300 can still control the drone 400 normally, even if its internal remaining power is insufficient.

[0045] Similarly, since the mains power 100 provides alternating current and its effective voltage is higher than the operating voltage of the load 300, it is preferable that a second switching power supply 16 be provided between the first electrical connector 11 and the third electrical connector 13 in this embodiment, so as to step down the voltage between the mains power 100 and the load 300.

[0046] The charging of battery 200 by mains power 100 and the supply of power to load 300 by mains power 100 can be carried out simultaneously or one of them can be selected.

[0047] Unlike existing technologies, the battery 200 in this embodiment also has a first power supply state. When the remaining power in the load 300 is insufficient and the first electrical connector 11 is difficult to connect to the mains power 100 (such as when the user is in an outdoor environment), the excess battery 200 can be installed on the housing 1 and electrically connected to the second electrical connector 12, so that this part of the excess battery 200 switches to the first power supply state. At the same time, the load 300 is electrically connected to the third electrical connector 13. At this time, the excess battery 200 can serve as an emergency power source and provide emergency power to the load 300 through the second electrical connector 12 and the third electrical connector 13, ensuring the normal use of the load 300 and thus allowing the drone 400 to fly normally.

[0048] Since the current supplied by the battery 200 to the load 300 is DC, and the voltage supplied by the battery 200 is usually greater than the operating voltage of the load 300, it is preferable that a BUCK circuit 14 be provided between the second electrical connector 12 and the third electrical connector 13 in this embodiment, and the BUCK circuit 14 be used to step down the DC voltage between the battery 200 and the load 300.

[0049] In response to the working scenario where the remaining power in the load 300 is insufficient and the first electrical connector 11 is difficult to connect to the mains power 100, some batteries 200 are in the first power supply state so that the load 300 can wirelessly connect to the drone 400 and control the drone 400. At the same time, some batteries 200 are in the second power supply state to ensure the normal flight of the drone 400.

[0050] Furthermore, in this embodiment, the housing 1 is also equipped with a main control board 17, a first detection module 18, and a first switch module 19. The first electrical connector 11, the second switching power supply 16, and the main control board 17 are electrically connected in sequence.

[0051] The first detection module 18 is used to detect the electrical connection status between the first electrical connector 11 and the mains power 100 and is electrically connected to the main control board 17. For example, in this embodiment, one end of the first detection module 18 is connected to the line between the second switching power supply 16 and the main control board 17, and the other end is directly electrically connected to the main control board 17. The first switch module 19 is disposed between the second electrical connector 12 and the BUCK circuit 14, and is electrically connected to the main control board 17. The first switch module 19 is used to control the conduction state between the second electrical connector 12 and the BUCK circuit 14.

[0052] For example, the first switch module 19 is an electromagnetic relay. The input terminal of the electromagnetic relay is electrically connected to the second electrical connector 12; the high-voltage output port of the electromagnetic relay is electrically connected to the BUCK circuit 14; the low-voltage communication port of the electromagnetic relay is directly electrically connected to the main control board 17, so that the main control board 17 can regulate the on / off state of the high-voltage output port of the electromagnetic relay.

[0053] More specifically, the housing 1 is equipped with a third switch module 113 and a second detection module 110. The third switch module 113 is located between the BUCK circuit 14 and the second switching power supply 16, and is also directly electrically connected to the main control board 17. The first switch module 19, the BUCK circuit 14, and the main control board 17 are sequentially electrically connected. The second detection module 110 is used to detect the electrical connection status between the second electrical connector 12 and the battery 200 and is electrically connected to the main control board 17. For example, in this embodiment, one end of the second detection module 110 is connected to the line between the BUCK circuit 14 and the main control board 17, and the other end is directly electrically connected to the main control board 17.

[0054] The first detection module 18 and the second detection module 110 can be ADC pins, which is existing technology and will not be described further in this embodiment.

[0055] When the first electrical connector 11 is not connected to the mains power 100, the first switch module 19 is in the closed state. As long as the second electrical connector 12 is connected to the battery 200, the battery 200 can supply power to the main control board 17 in sequence through the second electrical connector 12, the first switch module 19, and the BUCK circuit 14. After the main control board 17 receives power, it learns through the second detection module 110 that the second electrical connector 12 has been connected to the battery 200, and then controls the third switch module 113 to close. At this time, as long as the load 300 is connected to the third electrical connector 13, the battery 200 can provide emergency power to the load 300 in sequence through the second electrical connector 12, the first switch module 19, the BUCK circuit 14, the third switch module 113, and the third electrical connector 13.

[0056] When the first electrical connector 11 is connected to the mains power 100, the mains power 100 supplies power to the main control board 17 sequentially through the first electrical connector 11 and the second switching power supply 16. After receiving power, the main control board 17, based on the first detection module 18 knowing that the first electrical connector 11 has been connected to the mains power 100, can send a signal to the low-voltage communication port of the first switching module 19 to disconnect the high-voltage output port of the first switching module 19. At this time, even if the battery 200 is connected to the second electrical connector 12, the battery 200 cannot supply power to the third electrical connector 13 and the main control board 17 through the first switching module 19 and the BUCK circuit 14. After the main control board 17 knows that the first electrical connector 11 has been connected to the mains power 100, it will also control the third switching module 113 to close. At this time, as long as the load 300 is connected to the third electrical connector 13, the mains power 100 can supply power to the load 300 normally sequentially through the first electrical connector 11, the second switching power supply 16, the third switching module 113, and the third electrical connector 13.

[0057] Preferably, in this embodiment, a second switch module 111 is provided on the housing 1. The second switch module 111 is located between the first switching power supply 15 and the second electrical connector 12, and the second switch module 111 is also directly electrically connected to the main control board 17. After the first electrical connector 11 is connected to the mains power 100 and the second electrical connector 12 is connected to the battery 200, the main control board 17 needs to control the second switch module 111 to close so that the mains power 100 can charge the battery 200.

[0058] Since the power supply from battery 200 to load 300 is an unconventional emergency situation, it occurs infrequently. Therefore, and to simplify circuit design, this embodiment only provides the second electrical connector 12 in some battery slots 114, while the other battery slots 114 are equipped with the fourth electrical connector 112. The fourth electrical connector 112 and the second electrical connector 12 are connected in parallel to the second switch module 111. After the first electrical connector 11 is connected to the mains power 100, the fourth electrical connector 112 is connected to the battery 200, and the second switch module 111 is closed, the mains power 100 can charge the battery 200 at the fourth electrical connector 112 through the housing 1. Consistent with existing technology, the battery 200 at the fourth electrical connector 112 cannot supply power to the load 300 at the third electrical connector 13 through the fourth electrical connector 112.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
