Common device switches include mechanical switches and electronic switches, such as capacitive touch switches and self-locking switches. Among them, capacitive touch switches rely on the charging and discharging process of capacitors, are sensitive to the external environment, are easily affected by electrostatic interference, prone to failure, and have a large dependence on the power supply, and cannot work properly when the power supply is unstable; self-locking switches are greatly affected by external mechanical vibrations, are prone to deformation, causing the switch function to fail, and at the same time, the volume of self-locking switches is large and cannot be applied to miniaturized devices. Summary of the Invention

[0003] The present disclosure addresses the above problems and proposes a power-on and power-off system and method for miniaturized devices.

[0004] To solve at least one of the above technical problems, the present disclosure proposes the following technical solutions:

[0006] A power supply module, a tactile switch, a switch module, a power-on detection module, a main control module, and a power-on control module. The power supply module is electrically connected to the main control module through the switch module, and the power supply module can supply power to the main control module. The tactile switch is electrically connected to the switch module and the power-on detection module respectively. The power-on detection module is electrically connected to the main control module. The main control module is electrically connected to the power-on control module. The power-on control module is electrically connected to the switch module, and the power-on control module can control the conduction and disconnection of the switch module according to the instruction issued by the main control module.

[0007] In some embodiments, the switch module includes an MOS transistor Q1.

[0028] In order to make the purpose, technical solutions and advantages of the present disclosure more clear, the following further details the present disclosure in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are part of the embodiments of the present disclosure, rather than all of the embodiments, and are only used to explain the present disclosure, not to limit the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts belong to the scope of protection of the present disclosure.

[0029] It should be noted that the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or server that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0030] Embodiment 1:

[0031] Refer to the attached Figure 1-2 , which shows the power-on and power-off system of the miniaturized device provided by an embodiment of the present application, including: a power supply module 1, a tactile switch 2, a switch module 3, a power-on detection module 4, a main control module 5, a power-on control module 6, and a filtering module 7.

[0032] Among them, the power supply module 1 is electrically connected to the main control module 5 through the switch module 3. When the switch module 3 is turned on, the power supply module 1 can supply power to the main control module 5. The power-on detection module 4 can collect the electrical signals when the touch switch 2 is pressed or released and send them to the main control module 5. The main control module 5 can judge the user's intention of power-on, power-off or accidental touch according to the signals sent by the power-on detection module 4 and issue corresponding instructions. The power-on control module 6 can control the conduction and disconnection of the switch module 3 according to the instructions issued by the main control module 5.

[0033] The touch switch 2 is electrically connected to the switch module 3 and the power-on detection module 4 respectively. The power-on detection module 4 is electrically connected to the main control module 5. The main control module 5 is electrically connected to the power-on control module 6. The power-on control module 6 is electrically connected to the switch module 3. The filtering module 7 is electrically connected to the touch switch 2.

[0034] The power supply module 1 can be a battery or an external power supply. When the power supply module 1 is an external power supply, a corresponding power conversion module can be configured. The power conversion module is used to convert the external power supply into the voltage required by the main control module 5.

[0035] In this embodiment, the power supply module 1 is a battery. Refer to the attached Figure 1 description. In the figure, P1 is the battery output connector for connecting the battery, and Power represents the battery voltage.

[0036] One end of the touch switch 2 is electrically connected to the negative electrode of the power supply module 1, and the other end is connected to the switch module 3 through the diode D1 and the resistor R4. The switch module 3 can include a MOS transistor Q1. The MOS transistor Q1 can be a P-channel MOS transistor. The source electrode of the MOS transistor Q1 is electrically connected to the positive electrode of the power supply module 1. The drain electrode of the MOS transistor Q1 is electrically connected to the power input terminal Power-IN of the main control module 5. The gate electrode of the MOS transistor Q1 is connected to the resistor R4. A resistor R1 is connected between the gate electrode and the source electrode of the MOS transistor Q1. The drain electrode of the MOS transistor Q1 is grounded through the capacitor C1.

[0037] The end of the touch switch 2 not electrically connected to the negative electrode of the power supply module 1 is also connected to the power-on detection module 4. Specifically, the power-on detection module 4 includes a series-connected diode D2 and resistor R6. The diode D2 is electrically connected to the touch switch 2, and the resistor R6 is electrically connected to the signal input terminal SW1-IN of the main control module 5.

[0038] The main control module 5 can be a single-chip microcomputer.

[0039] The power-on control module 6 may include a triode Q2, the triode Q2 may be an NPN triode, the base of the triode Q2 is electrically connected to the signal output terminal Power-ON of the main control module 5 through a resistor R5, the collector of the triode Q2 is electrically connected to the gate of the MOS tube Q1 in the switch module 3, the emitter of the triode Q2 is grounded, and a resistor R7 is connected between the base and the emitter of the triode Q2.

[0040] The filtering module 7 includes an electrostatic protection diode ESD1 and a capacitor C2 connected in parallel, wherein one end of the electrostatic protection diode ESD1 is grounded. The capacitor C2 is used to make the electrical signal after the touch switch 2 is pressed smoother, filter out the clutter in the signal, improve the anti-interference ability of the system, and ensure the purity and stability of the signal transmission after the touch switch 2 is pressed. The electrostatic protection diode ESD1 is used to introduce the static electricity brought when the touch switch 2 is pressed into the ground wire, thereby preventing the static electricity from damaging the system.

[0041] When the power-on and power-off system of the miniaturized device provided by the embodiment of the present invention works, when the touch switch 2 is pressed, since one end of the touch switch 2 is connected to the negative power supply, after the touch switch 2 is pressed, the 3rd pin of the diode D1 is at a low level, and the 2nd pin of the diode D1 is also at a low level. Therefore, the voltage difference between the gate and the source of the MOS tube Q1 is greater than the threshold voltage of the MOS tube Q1, and at this time the MOS tube Q1 is turned on. The voltage Power provided by the power supply module 1 flows through the MOS tube Q1 to the power input terminal Power-IN of the main control module 5 to supply power to the main control module 5, and the main control module 5 powers on and starts to work.

[0042] At the same time, the low-level signal after the touch switch 2 is pressed is input to the signal input terminal SW1-IN of the main control module 5 through the 1st pin of the diode D1. When the main control module 5 powers on and works, it can time the duration when the touch switch 2 is pressed. When the duration when the touch switch 2 is pressed is greater than a preset value, the main control module 5 recognizes that the user presses the touch switch and attempts to power on. The signal output terminal Power-ON of the main control module 5 outputs a high level to turn on the triode Q2. When the triode Q2 is turned on, the voltage difference between the gate and the source of the MOS tube Q1 is always greater than the threshold voltage of the MOS tube Q1, the MOS tube Q1 is always turned on, and the power supply module 1 continuously supplies power to the main control module 5. At this time, even if the hand is released and the touch switch 2 is no longer pressed, the power will not be cut off, and the system maintains the power-on state, and the power-on is successful.

[0043] When the system is in the boot state, when the main control module 5 detects that the touch switch 2 is pressed again, the main control module 5 measures the duration for which the touch switch 2 is pressed. When the duration for which the touch switch 2 is pressed is greater than a preset value, the main control module 5 recognizes that the user presses the touch switch and attempts to shut down. The signal output terminal Power-ON of the main control module 5 outputs a low level to turn off the triode Q2. When the user releases the touch switch 2, the voltage difference between the gate and the source of the MOS transistor Q1 disappears and is no longer greater than the threshold voltage of the MOS transistor Q1. The MOS transistor Q1 is turned off, Power-IN is powered off, and the main control module 5 is powered off to achieve shutdown.

[0044] The beneficial effects of the present disclosure are as follows. By providing a touch switch, it can better meet the miniaturization and lightweight requirements of small-sized devices. The touch switch has a rapid response and can adapt to various harsh environments, improving the reliability of the device. While meeting the requirements of power-on and power-off, it simplifies the circuit design, further reduces the volume of the device, and lowers the product cost.

[0045] Embodiment 2:

[0046] Refer to the attached Figure 3 of the specification. The present application also provides a power-on and power-off method for a small-sized device, which is applied to the power-on and power-off system of any of the foregoing small-sized devices, and includes the following steps:

[0047] S101: Power on the main control module,

[0048] S102: Detect that the touch switch is pressed and measure the time for which the touch switch is pressed;

[0049] S103: Determine whether the time for which the touch switch is pressed exceeds a preset value. If the time for which the touch switch is pressed exceeds the preset value, execute S104; if the time for which the touch switch is pressed does not exceed the preset value, return to execute S102. If the touch switch is released before executing S104, the main control module is directly powered off and the boot process ends;

[0050] S104: The main control module sends a signal to the power-on control module,

[0051] S105: The power-on control module is turned on, and then the switch module is turned on, and the power supply module continuously supplies power to the main control module to maintain the boot state;

[0052] S106: The main control module continuously monitors whether the touch switch is pressed again; when it is detected that the touch switch is pressed, execute S107. If it is not detected that the touch switch is pressed, execute S106;

[0053] S107: Measure the time for which the touch switch is pressed;

[0054] S108: Determine whether the pressing time of the touch switch exceeds a preset value; if the pressing time of the touch switch exceeds the preset value, execute S109, if the pressing time of the touch switch does not exceed the preset value, then return to execute S107. Before the pressing time of the touch switch exceeds the preset value, if the touch switch is released, it is determined as a false touch and no operation is performed.

[0055] S109: The main control module controls the power-on control module to disconnect.

[0056] After the power-on control module is disconnected, if the touch switch is released, the main control module is powered off and the shutdown ends.

[0057] The same content as in Embodiment 1 will not be elaborated here.

[0058] The beneficial effects of the present disclosure are that by setting the touch switch, it can better meet the miniaturization and lightweight requirements of small-sized devices. The touch switch has a rapid response and can adapt to various harsh environments, improving the reliability of the device. While meeting the power-on and power-off requirements, it simplifies the circuit design, further reduces the volume of the device, and reduces the product cost.
