Description of the Drawings

[0017] The following will clearly show the technical solutions and their beneficial effects of the present utility model by describing the specific embodiments of the present utility model in detail with reference to the drawings.

[0018] Figure 1 is a schematic circuit structure diagram of the charging device of the present utility model;

[0019] Figure 2 is a schematic diagram of the connection between the power supply device and the charging device of the present utility model. Detailed Embodiments

[0020] Please refer to the drawings, where the same component symbols represent the same components. The principle of the present utility model is illustrated by being implemented in a suitable computing environment. The following description is based on the specific embodiments of the present utility model illustrated, and it should not be regarded as limiting other specific embodiments of the present utility model not described in detail herein.

[0021] The charging device for a power supply device of the present utility model can be applied to the charging of a shared power bank, that is, the power supply device can be a mobile power source such as a shared power bank, or other types of batteries, etc. The charging device can be, for example, a Type-c data cable.

[0022] Refer to Figure 1 and Figure 2, the charging device for a power supply device according to an embodiment of the present invention includes a Type-c plug 101 and a main control board 102. The Type-c plug 101 is also the Type-C1 shown in the figure, and the main control board 102 has a control circuit.

[0023] The control circuit includes a main control unit U1, a three-terminal resistor R2, and a first resistor R1. The Type-c plug 101 includes an SBU1 pin and an SBU2 pin. The first end of the three-terminal resistor R2 is connected to the SBU1 pin, the second end of the three-terminal resistor R2 is connected to the SBU2 pin, and the third end of the three-terminal resistor R2 is connected to the main control unit U1 through the first resistor R1, so that when the Type-c plug 101 is connected to the Type-c interface of the power supply device 20, the power supply device 20 obtains a predetermined trigger signal, and the power supply device 20 performs a charging operation under the trigger of the predetermined trigger signal. When the Type-c plug 101 is not inserted into the Type-c interface of the power supply device, the Type-c plug 101 defaults to a high-level mode. When inserted into the power supply device 20, the working mode is recognized as low level, and the encrypted charging of the power supply device 20 is started.

[0024] It can be understood that as Figure 2 shown, when the Type-c plug 101 is connected to the Type-c interface, the SBU1 pin and the SBU2 pin of the Type-c plug 101 are respectively connected to the SBU1 pin and the SBU2 pin of the Type-c interface.

[0025] Therefore, the charging device of the present invention uses the three-terminal resistor R2 and the first resistor R1 for signal triggering, so that the power supply device 20 can perform a charging operation only under a predetermined trigger signal, that is, the power supply device 20 can perform a charging operation only when it is equipped with the above charging device. When the power supply device 20 is a shared power bank, the above charging device can be applied to the charging cabinet of the shared power bank. The shared power bank can be used normally after being lent out, but it needs to be sent back to the charging cabinet for charging. Therefore, even if the shared power bank is stolen, the thief cannot charge it, thereby reducing the risk of theft and realizing the anti-theft function of the shared power bank. At the same time, it is not necessary to collect the personal information of consumers, effectively protecting the privacy of consumers.

[0026] Among them, the three-terminal resistor R2 is a variable resistor.

[0027] Among them, the predetermined trigger signal is a low-level trigger signal. When the Type-c plug 101 is connected to the Type-c interface of the power device 20, the charging device is in the low-level mode. Through the action of the three-terminal resistor R2 and the first resistor R1, the SBU1 pin and the SBU2 pin of the Type-c plug 101 output low levels. As a result, the SBU1 pin and the SBU2 pin of the Type-c interface of the power device 20 are pulled down to low levels, so that the power device 20 obtains the predetermined trigger signal. The SBU1 and SBU2 of the conventional Type-c data cable plug are usually directly connected to the main control unit. Different from the conventional Type-c data cable, the SBU1 pin and the SBU2 pin of the Type-c plug of the present invention are connected with the resistor R1 and the resistor R2 to generate a low-level trigger signal, and the power device 20 can be awakened only when the signals of the SBU1 pin and the SBU2 pin of the Type-c interface are at low levels, and then the charging operation is carried out. Among them, when the power device 20 uses a conventional Type-c data cable or is suspended without a data cable plugged in, the signals of its SBU1 pin and SBU2 pin are at high levels. At this time, the power device 20 cannot be awakened, so the charging operation cannot be carried out. Therefore, using a conventional data cable to charge the power device 20 of the present invention, or using the charging device of the present invention to charge other power devices 20, does not work. Only when the charging device of the present invention and the power device 20 are suitable for matching use can they work, which can reduce the risk of theft.

[0028] Further, the resistance value of the three-terminal resistor R2 is 1KΩ.

[0029] Further, the charging device of the present invention uses an external power switch synchronous buck controller for bucking. Its Type-c plug 101 further includes a VBUS pin, a CC1 pin, a CC2 pin and a GND pin. The control circuit further includes an H-MOS transistor G1, an L-MOS transistor G2 and a V-MOS transistor G3. The gate of the H-MOS transistor G1 is connected to the main control unit U1. The drain of the H-MOS transistor G1 is connected to the input signal. The source of the H-MOS transistor G1 and the drain of the L-MOS transistor G2 are both connected to the drain of the V-MOS transistor G3. The gate of the L-MOS transistor G2 is connected to the main control unit U1. The source of the L-MOS transistor G2 is grounded. The gate of the V-MOS transistor G3 is connected to the main control unit U1. The source of the V-MOS transistor G3 is connected to the VBUS pin of the Type-c plug 101. The CC1 pin and the CC2 pin are respectively connected to the main control unit U1. The GND pin is grounded.

[0030] An embodiment of the present utility model further provides a power supply component, which includes a power supply device and a charging device. The power supply device has a Type-c interface, and the charging device is the charging device described in the above embodiment. Among them, the power supply device can be, for example, a shared power bank, and the charging device can be, for example, a charging data cable.

[0031] The charging device for a power supply device of the present utility model includes a Type-c plug and a main control board with a control circuit; the control circuit includes a main control unit, a three-terminal resistor, and a first resistor; the Type-c plug includes an SBU1 pin and an SBU2 pin. The first end of the three-terminal resistor is connected to the SBU1 pin, the second end of the three-terminal resistor is connected to the SBU2 pin, and the third end of the three-terminal resistor is connected to the main control unit through the first resistor, so that when the Type-c plug is connected to the Type-c interface of the power supply device, the power supply device obtains a predetermined trigger signal, and the power supply device performs a charging operation under the trigger of the predetermined trigger signal. Therefore, the charging device uses the three-terminal resistor and the first resistor for signal triggering, so that the power supply device can only perform a charging operation under the predetermined trigger signal, that is, the power supply device can only perform a charging operation when it is equipped with the above charging device. When the power supply device is a shared power bank, the above charging device can be applied to the charging cabinet of the shared power bank. After the shared power bank is lent out, it can be used normally, but it needs to be sent back to the charging cabinet for charging. Therefore, even if the shared power bank is stolen, the thief cannot charge it, thereby reducing the risk of theft and realizing the anti-theft function of the shared power bank. At the same time, it is not necessary to collect consumers' personal information, effectively protecting consumers' privacy.
