[0075] In order to more clearly illustrate the present invention, the present invention is further described below in conjunction with preferred embodiments and accompanying drawings. Similar components in the accompanying drawings are represented by the same reference numerals. It should be understood by those skilled in the art that the content specifically described below is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0076] According to the existing problems of the prior art, such as Figure 1 As shown, an embodiment of the present invention provides a terminal device, including a power module, a wireless communication module, and a wireless control module respectively connected to the power module and the wireless communication module, wherein

[0077] The wireless control module includes a state switching circuit and a state maintaining circuit, and the wireless control module is configured as follows:

[0078] In a normal working state, the power supply mode of the power module to the wireless communication module is set to the first power supply mode according to the default requirement;

[0079] When switching the working state, the state switching circuit switches the first power supply mode to the second power supply mode in response to the trigger operation, the power supply state of the first power supply mode is opposite to that of the second power supply mode, and simultaneously starts the state maintaining circuit;

[0080] When the working state is maintained, in response to the cessation of the trigger operation, the state maintaining circuit is used to maintain the second power supply mode until the terminal device is turned off.

[0081] In this embodiment, by setting a wireless control module between the power module and the wireless communication module, it is possible to power the wireless communication module in the first power supply mode according to the default requirement when the power is turned on and working normally, and use the state switching circuit to switch the first power supply mode to the second power supply mode in response to the trigger operation, and then use the state maintaining circuit to maintain the second power supply mode when the trigger operation stops until the terminal device is turned off; this embodiment uses the hardware level to turn on or off the communication function of the wireless communication module by setting the wireless control module, that is, to physically cut off the wireless communication function, thereby meeting user needs and effectively improving the security of internal data of the terminal device, and has practical application value.

[0082] Specifically, according to user needs, for example, the terminal device is required to operate in a default mode of closing the wireless communication function after it is powered on and powered on normally. When wireless communication is required, such as transmitting data or receiving instructions, the wireless communication function of the terminal device is turned on through a trigger operation, and the normal use of the wireless communication function is maintained after the trigger operation ends; for another example, contrary to the above requirements, the wireless communication function is turned on after the power is turned on and powered on normally, and the wireless communication function is turned off and maintained when needed; the wireless control module of the terminal device of this embodiment is set according to the user's default needs, so that the wireless communication module is powered on in the default power supply mode when it is initially powered on and works normally; the power supply mode is switched through the state switching circuit when switching is required, and the switched power supply mode is maintained in response to a switch until the device is turned off. In other words, when the user's demand is to shut down the wireless communication function by default, the wireless communication module is stopped from being powered on, and when the wireless communication function is switched on in response to the trigger operation, the wireless communication module is powered on, and the power supply of the wireless communication module is maintained after the trigger operation ends, thereby physically shutting down or connecting the wireless communication function; vice versa, it can meet user needs and effectively improve the security of data inside the terminal device.

[0086] The first port of the first state switching circuit is connected to the output end of the power module to receive the first power signal, the second port of the first state switching circuit is connected to the second port of the second state maintaining circuit, the third port of the first state switching circuit is connected to the third port of the second state maintaining circuit, and the fourth port of the first state switching circuit is connected to the second power signal;

[0096] In this embodiment, the first power supply mode is not to supply power to the wireless communication module, that is, to turn off the wireless communication function; the second power supply mode is to supply power to the wireless communication module, that is, to turn on the wireless communication function. In this embodiment, the first trigger switch, the first switch, and the first resistor of the first state switching circuit switch the default first power supply mode to the second power supply mode in response to the trigger operation, and at the same time start the second switch of the second state maintaining circuit; when the trigger operation stops, the second switch and the second resistor of the second state maintaining circuit are used to maintain the conduction of the first switch, thereby maintaining the second power supply mode until the terminal device is turned off. In this embodiment, the default setting is to turn off the wireless communication function, and the wireless communication module is powered on by manually triggering to turn on the wireless communication function, so that the power supply to the wireless communication module can be controlled at the hardware level, that is, the wireless communication function is physically cut off, which meets the needs of users and effectively improves the security of the internal data of the terminal device, and has practical application value.

[0097] Specifically, the specific working process of this embodiment is described, which includes the following steps:

[0098] The first step is to power on and operate normally.

[0099] like Figure 4a As shown, after power-on, Q2 is turned off, the gate of Q1 is pulled up to a high level, Q1 is turned off, and no power is supplied to the wifi, which is the first power supply mode.

[0100] The second step is to manually press the first trigger switch to switch the first power supply mode to the second power supply mode.

[0101] like Figure 4b As shown, when S1 is pressed, the second power supply signal is at a low level, for example, grounded; the gate of Q1 is pulled down, Q1 is turned on, and power is supplied to the wifi, which is the second power supply mode. At the same time, R2 divides the voltage, and Q2 is turned on.

[0102] The third step is to release the first trigger switch to maintain the second power supply mode.

[0103] like Figure 4c As shown, release S1, R2 is the current limiting resistor, keep Q2 turned on, and then keep Q1 turned on, continue to supply power to the wifi, and maintain the second power supply mode until the power is cut off.

[0104] In this embodiment, the first trigger switch, the first switch, and the first resistor of the first state switching circuit switch the default first power supply mode to the second power supply mode in response to a trigger operation, and simultaneously start the second switch of the second state maintaining circuit; when the trigger operation stops, the second switch and the second resistor of the second state maintaining circuit are used to maintain the conduction of the first switch, thereby maintaining the second power supply mode until the terminal device is turned off.

[0132] In this embodiment, the default first power supply mode is switched to the second power supply mode by the third state switching circuit in response to the trigger operation, and the fourth state maintaining circuit is started at the same time; when the trigger operation stops, the fourth state maintaining circuit is used to maintain the second power supply mode until the terminal device is turned off. This embodiment is set to turn off the wireless communication function by default, and the wireless communication module is powered on by manual triggering to turn on the wireless communication function, so that the power supply to the wireless communication module can be controlled at the hardware level, that is, the wireless communication function is physically cut off, which meets the needs of users and effectively improves the security of the internal data of the terminal device, and has practical application value.

[0133] Specifically, the specific working process of this embodiment is described, which includes the following steps:

[0134] The first step is to power on and operate normally.

[0135] like Figure 8a As shown, after power-on, Q6 is turned off, the gate of Q5 is pulled up to a high level by R7 and R8, Q5 is turned off, and no power is supplied to the wifi, which is the first power supply mode.

[0136] The second step is to manually press the third trigger switch to switch the first power supply mode to the second power supply mode.

[0137] like Figure 8b As shown, press S3 to directly supply power to the WiFi, which is the second power supply method.

[0138] At the same time, R9 and R10 divide the voltage, and Q4 is turned on. The second power supply signal is at a low level, for example, grounded; the gate of Q5 is pulled down, and Q5 is turned on.

[0139] The third step is to release the third trigger switch to maintain the second power supply mode.

[0140] like Figure 8c As shown, release S3, R9 is a current limiting resistor, maintain Q6 on, and then maintain Q5 on, continue to supply power to the wifi, and maintain the second power supply mode until the power is cut off.

[0141] In this embodiment, the default first power supply mode is directly switched to the second power supply mode through the third trigger switch of the third state switching circuit, and the sixth switch of the fourth state maintaining circuit is started at the same time, and then the fifth switch of the third state switching circuit is started; when the trigger operation stops in response to the trigger operation, the sixth switch, the ninth resistor, the tenth resistor, the seventh resistor and the eighth resistor are used to maintain the conduction of the fifth switch.

[0142] Taking into account the misoperation of the trigger switch, in an optional embodiment, as Fig. 9 As shown, the third state switching circuit further includes a seventh switch Q7 connected in series with the third trigger switch S3, and the seventh switch Q7 includes a first end and a second end;

[0143] A first end of the seventh switch Q7 is connected to the eighth node, and a second end of the seventh switch Q7 is connected to a first end of the third trigger switch S3 .

[0144] In this embodiment, in order to prevent the user from accidentally triggering a button during use, thereby causing the wireless communication module to be mistakenly enabled, a seventh switch Q7 is added on the basis of the previous embodiment. The seventh switch Q7 can be in a normally open state or a normally closed state. When the seventh switch is disconnected, the third trigger switch is ineffective, and the third trigger switch is effective only when the seventh switch is closed, thereby avoiding misoperation.

[0145] Specifically, the seventh switch of the present embodiment is a switch activated by inserting a pin. When the seventh switch is in the normally closed state by default, the third trigger switch function can realize the function of temporarily turning on the wireless communication module; when the user does not want to enable the wireless communication function, the seventh switch can be adjusted from a closed state to an open state through a probe, thereby ensuring the safety of failure of the wireless communication module. In addition, according to user needs, the structural design can ensure that the changed state of the probe cannot be easily restored. For example, the hole position is set to only allow the insertion of the pin. When the insertion causes the seventh switch to change from normally closed to normally open, it can no longer be restored by the pin and can only be restored manually. The present embodiment effectively improves the stability of the wireless control module by adding the seventh switch, thereby improving the stability of the terminal device.

[0146] Similarly, based on Figure 5 In an optional embodiment, the aforementioned embodiment is as follows: Fig.14 As shown, the first state switching circuit further includes an eleventh switch Q11 connected in series with the second trigger switch S2, and the eleventh switch Q11 includes a first end and a second end;

[0147] A first end of the eleventh switch Q11 is connected to a second end of the second trigger switch S2 , and a second end of the eleventh switch Q11 is connected to the second power signal.

[0148] In this embodiment, in order to prevent the user from accidentally triggering a button during use, thereby causing the wireless communication module to be mistakenly enabled, an eleventh switch Q11 is added on the basis of the above embodiment. The eleventh switch Q11 can be in a normally open state or a normally closed state. When the eleventh switch is disconnected, the second trigger switch is not effective. Only when the eleventh switch is closed, the second trigger switch is effective, thereby avoiding misoperation. The specific implementation method is referred to the above embodiment, which will not be repeated here.

[0149] It is worth noting that if Figure 3 The embodiment shown may also add a normally open or normally closed switch such as the eleventh switch, thereby effectively improving the stability of the wireless control module and further improving the stability of the terminal device. The specific implementation method is referred to the above embodiment and will not be described again here.

In this embodiment, the default setting is to turn on the wireless communication function, and the wireless communication function is turned off by manually triggering the stopping of power supply to the wireless communication module, so that the power supply to the wireless communication module can be controlled at the hardware level, that is, the wireless communication function is physically cut off, which meets the needs of users and effectively improves the security of the internal data of the terminal device, and has practical application value.

[0160] Specifically, the specific working process of this embodiment is described, which includes the following steps:

[0161] The first step is to power on and operate normally.

[0162] like Fig.11a As shown, after power-on, Q10 is cut off, the current passes through R11 and R13 to reach the collector of Q9, Q9 is turned on, the gate of Q8 is pulled low, Q8 is turned on, and power is supplied to the wifi, which is the first power supply mode.

[0163] The second step is to manually press the fourth trigger switch to switch the first power supply mode to the second power supply mode.

[0164] like Fig.11b As shown, press S4, Q10 is turned on, both ends of R13 are pulled down by Q10, Q9 is turned off, Q8 is turned off, and no power is supplied to the wifi anymore, which is the second power supply mode.
