Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-7 , Embodiment 1: A multi-level power supply system with remote authorization, including a power input bus 1, a primary controlled power output bus 2, a secondary controlled power output bus 3, an internal power supply 6, a power switch 7, a wireless module 8, a power conversion module 9, an antenna 10, a power adapter 11, a power supply module 12, a cable of primary controlled power 13, a primary electrical appliance 14, and a secondary controlled power output port 15. The power input bus 1 is respectively connected to the internal power supply 6 and the power switch 7. The power switch 7 is also connected to the power conversion module 9 and the primary controlled power output bus 2. The internal power supply 6 is also connected to the wireless module 8. The wireless module 8 is also connected to the power switch 7 through a primary power enable signal terminal SW4.

[0027] An antenna 10 is also provided on the wireless module 8. A metering unit is provided between the power switch 7 and the primary controlled power output bus 2, and the metering of this metering unit exchanges information with the wireless module 8. A metering unit is provided between the power conversion module 9 and the secondary controlled power output bus 3, and the metering of this metering unit exchanges information with the wireless module 8. The wireless module is a WIFI module. The wireless module is a Bluetooth module.

[0028] The present invention also discloses a multi-level power control method with remote authorization. Using the above system, after the wireless module 8 is authorized by the remote rental system, it controls the power switch 7 through a primary power enable signal terminal SW to turn on the primary controlled power. The primary controlled power supplies power to the primary electrical appliance through the primary controlled power output bus 2, allowing the primary electrical appliance 14 to work. The primary electrical appliance 14 authorizes the power conversion module 9 through a secondary power enable signal terminal CTRL to start working, and outputs a secondary controlled power through the secondary controlled power output bus 3 for the user's secondary electrical appliance to use.

[0029] Embodiment 2. On the basis of Embodiment 1, the circuit of this design is as shown in Figure 2 . Among them: U1 is a three-terminal voltage regulator for providing internal power supply. C1 and C2 are the input and output side capacitors of U1 respectively; MD1 is a wireless module, LD1 is the working status indicator of this module, and R1 is the current-limiting resistor of LD1; ANT is the antenna of the wireless module; SW is the output control signal of the wireless module; Q1 is a MOSFET, which is the switch of a primary controlled power supply and is controlled by the SW signal to turn on / off the power supply of port P1. The primary electrical appliance draws power from port P1; MD2 is a DC-DC power conversion module, and its output is controlled by the CTRL signal; the CTRL signal comes from the primary electrical appliance and is the control signal for the primary electrical appliance to authorize MD2 to provide a secondary power supply externally; P2 to Pn are the power output ports of the DC-DC power conversion module MD2, that is, the secondary power output ports. Users use these ports to charge devices such as mobile phones, power banks, and digital cameras.

[0030] Embodiment 3. On the basis of Embodiment 1, the connection diagram of this design is as shown in Figure 3 . There is an information flow (such as a QR code) on the product that can be recognized by a mobile phone. After the user scans the code, the wireless module is authorized by the remote rental software system. The primary controlled power supply outputs from the primary controlled power cable 13 to provide power for the primary electrical appliance 14; then, the primary electrical appliance 14 provides an authorization signal for the secondary power supply to the power supply module 12 (that is, Figure 1 CTRL in). The output of the secondary power supply is controlled. The secondary power supply outputs from the secondary power output port 15. Users can draw power from the secondary power output port 15. In this embodiment, the secondary power supply is a 5V power supply. Users can use this to charge devices such as mobile phones, digital cameras, DV, and power banks. All components of the above-mentioned ( Figure 1 ) remote multi-level power supply system are installed in the power supply module 12. The cable for providing power to the power supply module 12 is a two-core cable, and the cable for supplying power to the primary electrical appliance 14 is a three-core cable (one core is used for each of the positive and negative power supplies, and one core is occupied by the authorization signal of the secondary power supply).

[0031] The basic feature of this embodiment is that all components of the above-mentioned remote multi-level power supply system are installed in the power supply module 12. The cable for providing power to the power supply module 12 is a two-core cable, and the cable for supplying power to the primary electrical appliance 14 is a three-core cable (one core is used for each of the positive and negative power supplies, and one core is occupied by the authorization signal of the secondary power supply).

[0032] In this embodiment, the wireless module is a WIFI module, which communicates with the remote rental software system through the wifi network in the space or the wifi hotspot opened by the mobile phone ←→ the 4G / 5G of the mobile phone or the newly developed mobile phone data communication network, etc. The remote rental software system authorizes the wifi module to output the enable signal SW of the primary controlled power supply to control the on / off of the primary controlled power supply; after the primary electrical appliance is powered on, the DC-DC module outputs the enable signal CTRL as needed to control the on / off of the secondary controlled power supply.

[0033] Embodiment 4, on the basis of Embodiment 3, the WIFI module can be replaced by a Bluetooth module with lower cost. After the mobile phone scans the code, it communicates with the remote rental software system through the space wifi network or the data communication network of the mobile phone. The authorization information of the remote rental software system communication is sent to the mobile phone, and the Bluetooth system of the mobile phone is automatically turned on. The ID information in the QR code is automatically paired with the Bluetooth module in the power supply module, and through this Bluetooth pair, the authorization of the remote rental software system is forwarded to the Bluetooth module in the power supply module, so that it provides the SW signal for the primary controlled power supply. The rest of the hardware and process are the same as above.

[0034] Obviously, as a remote multi-stage power supply system under this design concept, Figure 3 the shown connection method is not the only implementation scheme. And as more embodiments, Figures 4 to 7 different embodiments are disclosed. The difference between each embodiment is that the splitting of each functional part in this remote multi-stage power supply system is different, among which:

[0035] Embodiment 5, as Figure 4 , Figure 5 shown, in this embodiment, the DC-DC module for the secondary power supply is installed in the primary electrical appliance, the cable for supplying power to the power supply module 12 is a two-core cable, and the cable for supplying power to the primary electrical appliance 14 is also a two-core cable.

[0036] Embodiment 6, as Figure 6 shown, in this embodiment, the DC-DC module for the secondary power supply is installed in the power supply module 12, the cable for supplying power to the power supply module 12 is a two-core cable, and the cable for supplying power to the primary electrical appliance 14 is a three-core cable (one core is used for each of the positive and negative power supplies, and one core is occupied by the authorization signal CTRL of the secondary power supply). As Figure 6 a further solution of the embodiment, the authorization signal CTRL of the secondary power supply is not a simple level signal (for example, a low level prohibits the output of the secondary power supply, and a high level enables the output of the secondary power supply), but has certain encryption characteristics, such as a serial communication signal, or a continuous pulse signal, etc. After receiving and identifying the CTRL signal, the DC-DC module executes it.

[0037] Embodiment 7, as Figure 7As shown, in this embodiment, all components of the remote multi-stage power supply system are installed in the housing of the electrical appliance 14, and no additional components for the power supply module are provided.
