DETAILED DESCRIPTION

[0031] As described in the background, the existing power bank cabinet machine can meet the needs of people to charge electronic devices when going out, but the power bank cabinet machine cannot store and take the power bank without connecting to the mains. In order to solve this problem, the present application provides a cabinet machine power supply circuit which can meet the needs of people to charge electronic devices when going out, and can store and take the power bank without connecting to the mains.

[0032] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below. In the following description, a large number of specific details are set forth in order to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0033] Specifically, please refer to the accompanying drawings Figure 1 One embodiment of the present application provides a cabinet machine power supply circuit 1, which can include a charging module 10 and a power supply module 20.

[0034] More specifically, as Figure 1 shown, the power supply module 20 includes a power bank power supply interface, a cabinet machine charging end, a diode 21 is arranged between the power bank power supply interface and the cabinet machine charging end, the conduction direction of the diode 21 is from the power bank power supply interface to the cabinet machine charging end, the cabinet machine charging end is a mains input end, and the power bank power supply interface is a bidirectional end.

[0035] It is worth noting that the power bank power supply interface is in communication with the POGOPIN interface in the charging compartment 41 of the cabinet machine, when the charging cabinet 40 is not connected to the mains, the bidirectional charging and discharging power bank 42 is inserted into the charging compartment 41 through the POGOPIN interface, power is supplied to the charging cabinet 40 from the power bank power supply interface through the diode 21, thereby meeting the needs of the charging cabinet 40 to store and take the power bank 42 without connecting to the mains. POGOPIN interface is an interface for electrical connection and communication, which is usually applied in plugless connection design. Its main feature is to realize connection through spring contact, which is widely used in various electronic devices.

[0036] The working process of the above embodiment of the present application is as follows: when the cabinet power supply circuit 1 is not connected to the mains, the external power bank 42 is stored in the charging compartment 41 of the charging cabinet 40, and the power bank power supply interface is connected through the POGOPIN interface to supply power to the cabinet power supply circuit 1. Since the cabinet power supply circuit 1 is not connected to the mains, the voltage of the cabinet charging end is zero, and the conduction direction of the diode 21 is from the power bank power supply interface to the cabinet charging end, so that the power bank power supply interface supplies power to the cabinet charging end through the diode 21.

[0037] Optionally, as shown in the other embodiment of the present application also provides a cabinet power supply circuit 1, which comprises an energy charging module 10 and an energy supply module 20, the energy supply module 20 comprises a power bank power supply interface, a cabinet charging end, a diode 21 arranged between the power bank power supply interface and the cabinet charging end, the conduction direction of the diode 21 is from the power bank power supply interface to the cabinet charging end, the cabinet charging end is a mains input end, the power bank power supply interface is a charge-discharge bidirectional interface, and the external power bank 42 can supply power to the cabinet through the power bank power supply interface. Figure 2

[0038] Optionally, as shown in the other embodiment of the present application also provides a cabinet power supply circuit 1, which comprises an energy charging module 10 and an energy supply module 20, the energy supply module 20 comprises a power bank power supply interface, a cabinet charging end, a diode 21 arranged between the power bank power supply interface and the cabinet charging end, the conduction direction of the diode 21 is from the power bank power supply interface to the cabinet charging end, the cabinet charging end is a mains input end, the power bank power supply interface is a charge-discharge bidirectional interface, and the external power bank 42 can supply power to the cabinet through the power bank power supply interface. Figure 2

[0039] The input end of the cabinet output module 12 is a mains input end, and the output end can be connected with the power bank power supply interface for charging the power bank 42 when the mains is connected.

[0040] The voltage reduction module 11 is used to detect whether the power bank 42 is damaged when the cabinet output module 12 is connected to the mains, and to detect whether the power bank 42 supplies power to the cabinet when the cabinet output module 12 stops connecting to the mains.

[0041] Optionally, as shown in the other embodiment of the present application also provides a cabinet power supply circuit 1, which comprises an energy charging module 10 and an energy supply module 20, the energy supply module 20 comprises a power bank power supply interface, a cabinet charging end, a diode 21 arranged between the power bank power supply interface and the cabinet charging end, the conduction direction of the diode 21 is from the power bank power supply interface to the cabinet charging end, the cabinet charging end is a mains input end, the power bank power supply interface is a charge-discharge bidirectional interface, and the external power bank 42 can supply power to the cabinet through the power bank power supply interface. Figure 2

[0042] Optionally, as shown in the other embodiment of the present application also provides a cabinet power supply circuit 1, which comprises an energy charging module 10 and an energy supply module 20, the energy supply module 20 comprises a power bank power supply interface, a cabinet charging end, a diode 21 arranged between the power bank power supply interface and the cabinet charging end, the conduction direction of the diode 21 is from the power bank power supply interface to the cabinet charging end, the cabinet charging end is a mains input end, the power bank power supply interface is a charge-discharge bidirectional interface, and the external power bank 42 can supply power to the cabinet through the power bank power supply interface. Figure 2 ​​​As shown, in another embodiment, the first voltage dividing resistor and the second voltage dividing resistor have the same resistance value. In this way, according to the voltage dividing principle, the voltage value at the third end of the voltage reduction module 11 is half of the voltage value of the power bank power supply interface, and the voltage value at the third end of the voltage reduction module 11 is more convenient to measure.

[0043] In particular, the first voltage dividing resistor and the second voltage dividing resistor can also have different resistance values.

[0044] Optionally, as Figure 2 As shown, in another embodiment, the cabinet machine output module 12 includes a switch module 121, a first filter energy storage module 122, and a second filter energy storage module 123. The switch module 121 is turned on when the city power is connected and there is a power bank 42 in the charging cabinet 40 that needs to be charged, and the input city power is output.

[0045] In particular, as Figure 2 As shown, the first end of the first filter energy storage module 122 is connected to the voltage input end of the switch module 121, and the second end of the first filter energy storage module 122 is grounded. The first end of the second filter energy storage module 123 is connected to the power bank charging end of the switch module 121, and the second end of the second filter energy storage module 123 is also grounded. In this way, the first filter energy storage module 122 and the second filter energy storage module 123 are provided to reduce fluctuations and interference in the circuit, thereby maintaining the stability of the circuit and the normal operation of the equipment. The filter energy storage module can provide additional power support when the power supply is unstable, thereby ensuring the stability of the circuit.

[0046] In particular, as Figure 2 As shown, the first filter energy storage module 122 and the second filter energy storage module 123 are both formed by two capacitors with different capacitance values connected in parallel, i.e. the two ends of the two capacitors with different capacitance values in the first filter energy storage module 122 are respectively connected to the voltage input end of the switch module 121 and the ground, and the two ends of the two capacitors with different capacitance values in the second filter energy storage module 123 are respectively connected to the power bank charging end of the switch module 121 and the ground.

[0047] Optionally, as Figure 2 As shown, in another embodiment, the switch module 121 includes a voltage input end, an enable end, and a power bank charging end. The enable end is used to control the conduction state of the voltage input end and the power bank charging end.

[0048] It is worth noting that only when the cabinet machine is connected to the city power and the power bank 42 that can only be charged by the POGOPIN interface needs to be charged, the enable end will make the voltage input end and the power bank charging end conductive.

[0049] In particular, by means of the enable terminal and the third terminal of the voltage reduction module 11 short-circuit, it can be judged whether the power bank 42 which can only be charged by itself through the POGOPIN interface is damaged. That is, in the case of connecting the cabinet to the mains, if there is a power bank 42 to be charged, the enable terminal makes the voltage input terminal conductive with the power bank charging terminal, that is, the power bank charging terminal is connected to the mains. If the power bank 42 is damaged, that is, the power bank power supply interface is grounded, the voltage reduction module 11 is short-circuited, and the third terminal of the voltage reduction module 11 has no voltage. Therefore, in the case of connecting to the mains, when the enable terminal makes the voltage input terminal conductive with the power bank charging terminal and the voltage value of the third terminal of the voltage reduction module 11 short-circuit is zero, the power bank 42 is damaged.

[0050] In particular, by means of the enable terminal and the third terminal of the voltage reduction module 11 short-circuit, the cabinet can enter a low-power mode. That is, the charging cabinet 40 has only the functions of renting and returning the power bank 42 without connecting to the mains, and does not have the function of charging the power bank 42 which can only be charged by itself through the POGOPIN interface. Since the charging cabinet 40 in the low-power mode is not connected to the mains, the enable terminal does not make the voltage input terminal conductive with the power bank charging terminal. In the case of inserting the power bank 42 which can be bidirectionally charged and discharged through the POGOPIN interface into the charging compartment 41, power is supplied to the power bank power supply interface through the POGOPIN interface, the power bank power supply interface supplies power to the charging cabinet 40 through the diode 21, and the third terminal of the voltage reduction module 11 has voltage. Therefore, in the case of not connecting to the mains, in the case that the enable terminal does not make the voltage input terminal conductive with the power bank charging terminal and the third terminal of the voltage reduction module 11 has voltage (the power bank 42 supplies power to the charging cabinet 40), the charging cabinet 40 enters a low-power mode and has only the functions of renting and returning the power bank 42.

[0051] It is worth noting that, as shown in Figure 3 , the third embodiment of the present application provides a charging cabinet 40, which comprises a plurality of charging compartments 41 and the cabinet power supply circuit 1.

[0052] It is worth noting that, as shown in Figure 4 , the fourth embodiment of the present application provides a charging cabinet 40, which comprises a plurality of charging compartments 41, a plurality of power banks 42, and the cabinet power supply circuit 1.

[0053] Optionally, in the fourth embodiment, the plurality of power banks 42 includes a first group of the power banks 42 and a second group of the power banks 42, the charging interface of the power banks 42 in the first group is a bidirectional charging and discharging interface, i.e. the power banks 42 with the bidirectional charging and discharging interface can perform bidirectional charging and discharging via the POGOPIN interface, and the charging interface of the power banks 42 in the second group is a unidirectional charging interface, i.e. the power banks 42 with the unidirectional charging interface can only charge itself via the POGOPIN interface.

[0054] Optionally, in the fourth embodiment, the charging interface of the plurality of power banks 42 is a bidirectional charging and discharging interface.

[0055] In particular, the power banks 42 with the bidirectional charging and discharging interface are used as power supply and inserted into the charging bin 41 of the charging cabinet 40, and the scheme of supplying power to the charging cabinet 40 also has an anti-theft function, without the need to externally mount the power supply outside the charging cabinet 40, which not only facilitates carrying but also reduces the overall volume of the additional power supply, thereby making the charging cabinet 40 more convenient to carry.

[0056] In particular, the charging cabinet 40 can be placed in a mobile vehicle or in the field for rental business.

[0057] In particular, a plurality of power banks 42 with the bidirectional charging and discharging interface can be arranged in the charging cabinet 40, so that the charging cabinet 40 can continuously work without power failure, thereby increasing the endurance of the charging cabinet 40.
