[0037] See also Figures 1 to 4As shown, an embodiment of the present application provides a mobile charging device, comprising a housing 1, an input charging gun 2, and an output charging gun 3. The housing 1 has a cavity, an air inlet 11, and an air outlet 12. A circuit assembly and a fan are disposed within the cavity. The circuit assembly includes a DC / DC module. The air inlet 11 and the air outlet 12 are both connected to the cavity. The housing 1 is provided with wheels 4 and a handle 5, which is used for gripping. The output charging gun 3 is connected to the housing 1, and the input charging gun 2 is electrically connected to the input terminal of the DC / DC module. The output charging gun 3 is connected to the housing 1 and is electrically connected to the output terminal of the DC / DC module. The mobile charging device of the present application is provided with a DC / DC module. Therefore, the input charging gun of the mobile charging device is connected to a battery in stock. The DC / DC module converts the output current of the battery in stock, and the output charging gun can directly output DC power to charge the battery in need. Because multiple conversions between AC and DC are not required, energy loss during the charging process is reduced, and charging efficiency is also improved. Furthermore, the mobile charging device of the present application can charge the vehicle by directly connecting to the inventory battery. The mobile charging device does not need to be set at a fixed point. The mobile charging device rotates with the location of the inventory battery, so that there is no restriction on the charging site. The mobile charging device of the present application has wheels 4 and handles 5, which can be easily moved and connected to the inventory battery. When the mobile charging device of the present application connects the inventory battery and the battery to be charged, the input charging gun 2 is connected to the inventory battery, and the output charging gun 3 is connected to the battery to be charged. There is no need to use DC-to-AC equipment and long-distance cables, which makes the transfer between the inventory battery and the rechargeable battery more convenient and reduces the transfer cost.

[0038] In some possible implementation schemes, the mobile charging device also includes a battery, which is arranged in the box body 1, and the battery is electrically connected to the circuit assembly. The circuit assembly includes a connecting circuit and control devices such as touch elements, control devices and main control boards arranged in the mobile charging device. These control devices need to be powered on in advance before the mobile charging device can be started to realize DC / DC conversion between the inventory battery and the battery to be charged. Existing similar mobile charging devices need to be connected to the mains power to be started, which is inconvenient to operate, and it is often difficult to find available mains power in places where emergency charging is required. The mobile charging device of the present application is provided with a battery, which can directly power internal devices such as touch elements, control devices and main control boards, so that the mobile charging device can be started at any time and is more convenient to use.

[0039] In some possible implementations, a power interface is provided on the housing 1, the power interface being connected to the circuit assembly via a power supply circuit, and the power interface being electrically connected to the battery via a charging circuit. When the mobile charging device is connected to the stored battery and the battery to be charged, the power interface can be connected to power supplying control components such as the touch element, control components, and main control board, thereby directly achieving DC / DC conversion between the stored battery and the battery to be charged. The power interface can be connected to power to charge the battery, making it convenient for use later when it is inconvenient to connect to the power supply. The power interface is primarily connected to the mains.

[0040] In some possible implementations, the housing 1 has a cavity 13, and the power interface is located in the cavity 13. In this way, the power interface does not protrude from the housing 1. The power interface is protected by the four walls of the cavity 13, is not easily impacted, and can also prevent rainwater from entering, reducing the possibility of damage to the power interface.

[0041] In some possible implementations, the housing 1 has an operating area 7, which includes a DC control switch 71 and an AC control switch 72. The DC control switch 71 is used to connect or disconnect the circuit between the battery and the circuit assembly, and the AC control switch 72 is used to control the connection and disconnection between the power interface and the power supply circuit and charging circuit. The DC control switch 71 in the operating area 7 controls whether the battery is connected to the circuit, and the AC control switch 72 controls whether the external power supply is connected to the circuit.

[0042] In some possible implementations, the mobile charging device includes a cover that is movably mounted on the housing 1 and is used to open or cover the operating area 7. The operating area 7 comprises a cabinet and a cover. The cabinet is embedded within the housing 1, and the DC control switch 71 and AC control switch 72 are both mounted within the cabinet. The cover can open or close the cabinet. The cabinet and cover protect the internal DC control switch 71 and AC control switch 72, preventing them from being accidentally turned on or off.

[0043] Furthermore, the cabinet is also provided with a debugging port 73, an Ethernet port 74, and a second power interface 75. The debugging port 73 can be connected to the debugging device, the Ethernet port 74 is used to access the network, and the second power interface 75 serves as a backup interface for the above power interface.

[0044] In some possible embodiments, a control panel 6 is provided on the top of the housing 1. The control panel 6 is electrically connected to the circuit assembly and includes a display screen 61, an indicator light 62, and an emergency stop button 63. The control panel 6 is exposed outside the housing 1. After turning on the switch in the operating area 7 to power on the control panel 6, the charging and discharging processes can be controlled through the control panel, and the charging and discharging conditions can be displayed, making it easy to observe the usage and facilitate timely operation. The control panel 6 can be touch-operated or key-operated. Preferably, the control panel 6 includes a touch screen that supports touch-operated output instructions.

[0045] In some possible implementations, a cable hanger 8 is provided on the housing 1. Both the input charging gun 2 and the output charging gun 3 are connected to the housing 1 via cables, which can be hooked to the cable hanger 8. Due to various environmental factors, the charged vehicle may be parked close to or far from the mobile charging device, and the mobile charging device may also be placed far from the battery pack. Therefore, the cable hanger is set to a longer length. If a longer cable is not required, the cable hanger can be wrapped around the cable hanger 8, which is neat and prevents damage to the cable.

[0046] In some possible implementations, the mobile charging device includes two wire hangers 8, one on each side of the top of the housing 1 along a first direction. The handle 5 is disposed on one side of the top of the housing 1 along a second direction, extending along the arrangement direction of the two wire hangers 8. The two wire hangers 8 are used to wind the cable connected to the input charging gun 2, and the other to wind the cable connected to the output charging gun 3. Winding them separately is more neat and convenient.

[0047] In some possible implementation schemes, a forklift matching structure 9 is provided at the bottom of the box body 1, and the forklift matching structure 9 includes two spacers arranged at intervals, and a forklift plug-in space is formed between the two spacers. Among them, a through hoisting matching hole can be provided on the spacer. In order to realize fast charging of the battery, the DC / DC module provided inside the mobile charging device has high power, so the volume and weight of the DC / DC module are also large. When transferring over a short distance, it can be pushed more easily by holding the push handle 5 with the help of a vehicle, but when transporting over a long distance, it needs to be placed on the vehicle for transportation. When the mobile charging device is placed on the transfer vehicle, a forklift or lifting equipment needs to be used. The forklift matching structure 9 provided at the bottom of the box body 1 can cooperate with the plug-in body of the forklift, so that the forklift's plug arm can be smoothly inserted into the forklift plug-in space. The forklift arm is limited between the two spacers, so that the forklift and the mobile charging device cooperate stably, and the mobile charging device can be stably transported and lifted. During hoisting, the lifting wire passes through the hoisting matching hole and is then connected to the hoisting equipment. The hoisting equipment lifts the mobile charging device through the lifting wire to ensure convenient and stable hoisting.

[0048] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments using the above-mentioned technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
