[0031] Embodiment 1:

[0032] like Figure 1 As shown, the utility model provides a discharge device for an external battery, including a housing 1, a battery connector 2, an electric energy conversion board 3 and at least one connecting mechanism 4. The electric energy conversion board 3 is arranged in the housing 1 and connected to the battery connector 2. The electric energy conversion board 3 is used to convert external electric energy and transmit it to the electrical equipment. The battery connector 2 is fixed on the housing 1.

The battery connector 2 is used to transmit the electric energy of the external battery to the electric energy conversion board 3. The connecting mechanism 4 is arranged on the housing 1, and at least one connecting mechanism 4 is arranged adjacent to the battery connector 2. The connecting mechanism 4 is used to limit and fix the external battery on the discharge device.

[0033] Specifically, the battery connector 2 is fixed on the shell 1 and is electrically connected to the power conversion board 3 fixed inside the shell 1. When the external electric energy (such as the electric energy of the external battery) is transmitted to the power conversion board 3 through the battery connector 2, the power conversion board 3 can convert the received electric energy (such as AC to DC, DC to AC, voltage reduction, etc.), so that the processed electric energy meets the current and voltage requirements of the electrical equipment (such as medical equipment). The power conversion board 3 can transmit the processed electric energy to the electrical equipment for use by the electrical equipment. The structure of the shell 1 is an L-shaped structure, and the number of connecting mechanisms 4 is preferably two, which are respectively arranged on the long side of the L-shaped structure and the short side of the L-shaped structure, so that the external battery can be connected to multiple places of the shell 1 through the connecting mechanism 4 to ensure the stability of the fixing of the shell 1. In addition, the number of connecting mechanisms 4 can also be adaptively set according to actual needs.

The mains input port 14 is used to connect the mains, and the power module 33 is connected to the mains input port 14 and the control conversion module 31. The power module 33 and the inverter module 32 are respectively fixed on both sides of the connecting plate. Specifically, the mains is connected to the power generation device through the mains input port 14 on the shell 1 of the power generation device. The mains input port 14 is electrically connected to the power module 33, and the mains input port 14 can transmit the connected mains to the power module 33.

The power module 33 can convert the received mains, and convert the voltage transmitted by the mains input port 14 into a direct current voltage of 18V through the DC terminal on the power module 33. Then the power module 33 transmits the direct current voltage of 18V to the control conversion module 31 electrically connected to the DC terminal of the power module 33. After receiving the AC power converted into 18V DC voltage, the control conversion module 31 can transmit it to the external battery to charge the external battery, or the MCU in the control conversion module 31 can transmit the 18V DC voltage to 3.3V and then transmit it to the inverter module 32 (such as Figure 6As shown in FIG. 1 , the inverter module 32 converts the mains power and supplies it to the power-consuming equipment. The power module 33 is arranged adjacent to the inverter module 32 and is fixed on both sides of the connecting plate. The structure of the housing 1 is an L-shaped structure. Preferably, the power module 33 and the inverter module 32 are arranged in the accommodating cavity of the long side area of ​​the L-shaped structure, parallel to the vertical direction, and the control conversion module 31 is arranged in the accommodating cavity of the short side area of ​​the L-shaped structure, parallel to the horizontal direction.

[0040] As an optional implementation, the control conversion module 31 includes a wireless communication element, a current control sensor and an MCU, the wireless communication element is connected to the MCU, and the MCU controls the wireless communication element to send the status information of the external battery.

The MCU controls the conversion module 31 to convert the electric energy of the mains or the electric energy of the external battery according to the electric energy value detected by the current control sensor. Specifically, the discharge device can be wirelessly connected to the terminal device through the wireless communication element. When the MCU receives the discharge of the external battery, when the stored power is lower than the set threshold, and when the mains is received to charge the external battery through the discharge device, after the external battery is charged, the MCU controls the wireless communication element to send information to the user's terminal device (such as a mobile phone, a computer, etc.), reminding that the external battery has run out of power, and timely replacing the external battery to ensure the stable operation of the electrical equipment, or reminding that the external battery is fully charged and stops charging.

The current control sensor can detect the electric energy value information received by the control conversion module 31. When the electric energy transmitted from the external battery to the control conversion module 31 and the electric energy transmitted from the mains power to the control conversion module 31 are received at the same time, since the electric energy transmitted by the mains power is greater than the electric energy transmitted by the external battery, the current control sensor can intuitively detect the electric energy transmitted by the mains power to the control conversion module 31.

The duration of the temporary power supply of the built-in backup battery 6 is determined according to the performance of the built-in backup battery 6, such as one minute. When the external battery is replaced, the built-in backup battery 6 stops supplying power to the electrical equipment. When the built-in backup battery 6 supplies power to the electrical equipment, by electrically connecting the built-in backup battery 6 to the inverter module 32, the built-in backup battery 6 can transmit power to the inverter module 32 for conversion processing, and the inverter module 32 converts the power into the current and voltage required by the electrical equipment, and transmits the power to the AC outlet 13, and the AC outlet 13 then supplies the processed power to the electrical equipment.
