Technical Field

[0001] This application relates to the field of power supply technology, and in particular to a power supply box. Background Technology

[0002] In a conventional power supply box, the control module controls either the smart lock or the ambient lighting on the door independently. Ambient lighting primarily refers to lights on the door other than those on the smart lock, such as the handle light. The keypad lights on the smart lock are controlled by the smart lock's control module and are not considered ambient lighting. Therefore, conventional power supply boxes contain too many control circuit boards, resulting in a cumbersome and inefficient structure. Summary of the Invention

[0003] Therefore, it is necessary to provide a power supply box that integrates the power distribution control module and the ambient light control module to address the aforementioned technical problems, thereby reducing the number of control circuit boards in the power supply box.

[0004] A power supply box includes a transformer and a control circuit board connected in sequence. The transformer is used to connect to an external power source and convert the voltage of the external power source into a first specified voltage before outputting it to the control circuit board.

[0010] Preferably, the control circuit board further includes a diode, the positive terminal of which is connected to the output terminal of the transformer, and the negative terminal of which is connected to the power supply port of the smart lock to provide 12V voltage to the smart lock.

[0011] Preferably, the power supply box is further configured with a first backup battery and a second backup battery, and the control circuit board is further configured with a first switch circuit and a second switch circuit.

[0012] Preferably, the first backup battery is a 12V backup battery and the second backup battery is a 7.4V backup battery.

[0013] Preferably, both the first switching circuit and the second switching circuit are switching transistors.

[0014] Preferably, the ambient light includes red, green, white, blue, and warm light; the control circuit board controls the switching on and off of different MOSFETs through software programs to control the LEDs of different colors to turn on and off.

[0015] Preferably, the power supply box further includes a Bluetooth module, and the control circuit board is connected to the APP through the Bluetooth module to receive instructions from the APP and control the LED lights of different colors to turn on and off according to the instructions.

[0016] The aforementioned power supply box includes a transformer and a control circuit board connected in sequence. The transformer is used to connect to an external power source, converting the voltage of the external power source into a first specified voltage and then outputting it to the control circuit board. The control circuit board is connected to a smart lock, providing the smart lock with a second specified voltage. The control circuit board is also electrically connected to an ambient light, outputting control information to the ambient light to control the LEDs of the ambient light to turn on and off.

[0022] To make the objectives, technical solutions, and advantages of this application clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0023] This application provides a power supply box. For example... Figure 1 As shown, a power supply box includes a transformer 100 and a control circuit board 200 connected in sequence. The transformer 100 is used to connect to an external power source, converting the voltage of the external power source into a first specified voltage and then outputting it to the control circuit board 200. The control circuit board is connected to a smart lock, providing the smart lock with a second specified voltage. The control circuit board is also electrically connected to an ambient light, and outputs control information to the ambient light to control the LED lights of the ambient light to turn on and off.

[0024] Wherein, the first specified voltage is 12V, and the transformer 100 is used to convert the voltage of the external power supply into 12V DC and output it to the control circuit board 200.

[0025] Specifically, the circuit of transformer 100 is as follows: Figure 2 As shown.

[0026] In one example, the control circuit board 200 is configured with a transformer module, which converts the 12V voltage into 8.6V and outputs it to the power supply port of the smart lock.

[0027] The transformer module includes a step-down DC-DC control chip. Specifically, the circuit of the transformer module is as follows: Figure 3 As shown.

[0028] In one example, the control circuit board also includes a diode, the positive terminal of which is connected to the output terminal of the transformer, and the negative terminal of which is connected to the power supply port of the smart lock to provide 12V voltage to the smart lock.

[0029] The power supply box is equipped with a first backup battery and a second backup battery. The control circuit board is equipped with a first switching circuit and a second switching circuit. The first switching circuit is connected to the power supply ports of the first backup battery and the smart lock, respectively. The second switching circuit is connected to the power supply ports of the second backup battery and the smart lock, respectively. Specifically, the first backup battery is a 12V backup battery, and the second backup battery is a 7.4V backup battery. Both the first and second switching circuits are switching transistors.

[0030] Specifically, such as Figure 4As shown, the 12V DC voltage from the transformer is isolated by diodes to power the 12V smart lock. The 12V DC voltage from the transformer is then converted by a step-down DC-DC control chip to reduce the 12V voltage to 8.6V to power the smart lock. When the household 220V AC power fails, the backup battery automatically starts, providing either 12V or 8.4V to power the smart lock.

[0031] In summary, the power supply box implemented in this application has the following judgment logic, switching path, and anti-reverse current / anti-conflict mechanism:

[0032] 1. Automatic backup battery detection logic during power outage: When the 220V AC power fails, the input 12V is 0V, and the gate of the MOSFET changes from high level to low level.

[0033] 2. Switching path: When the gate of the MOSFET changes from high level to low level, the MOSFET turns on, and the backup battery voltage provides normal voltage to the device through the MOSFET.

[0034] 3. Anti-reverse flow / anti-collision mechanism: A forward diode is connected to the 12V input to prevent battery voltage from flowing back to the 12V input terminal.

[0035] In one embodiment, the ambient light includes red, green, white, blue, and warm light; the control circuit board 200 controls the switching on and off of different MOSFETs via software programs to control the LEDs of different colors to turn on and off.

[0036] The power supply box also includes a Bluetooth module. The control circuit board is connected to the APP via the Bluetooth module to receive instructions from the APP and control the LEDs of different colors to turn on and off according to the instructions.

[0037] Specifically, the circuit of the ambient light is as follows: Figure 5 As shown, different MOSFETs are switched on and off via software, thereby controlling the LEDs of different colors to turn on and off, achieving the effect of ambient lighting.

[0038] In addition, the Bluetooth module in the power box interacts with the mobile app, receives signals from the phone, and controls the ambient light to turn on and off.

[0039] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
