[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0029] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0030] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The singular forms of "a", "said" and "the" used in this application and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0031] With the advent of the Internet of Things era, smart home appliances have become increasingly popular, and users can control them through input operations.

[0032] However, in order to respond to user input operations, a control module is usually required to detect and control the input operations, which increases the pin resource requirements of the control module and greatly increases product costs. In addition, the single control method leads to a relatively monotonous product design.

[0033] In order to improve the above-mentioned problems, the inventors proposed a switch control circuit and an electronic device provided in the present application, wherein the switch control circuit includes: a detection module, a power supply module and a functional module; wherein the detection module is used to continuously generate an input signal during the period of detecting the user's input operation; the power supply module is used to be connected to the detection module, and the power supply module is used to connect the path to the power supply according to the input signal when receiving the input signal; the functional module is used to be connected to the power supply module, and the functional module is used to work according to the conduction time of the power supply module when the power supply module is connected to the power supply; thereby, a new control circuit is provided to realize the control of the functional module according to the user's input operation without adopting the control module, thereby effectively reducing the cost of the product and enriching the direction of product design and the user's usage experience.

[0034] The switch control circuit provided in the embodiment of the present application will be described in detail below through specific implementation.

[0035] See also Figure 1 , Figure 1 A switch control circuit 100 provided in an embodiment of the present application is shown, and the switch control circuit can be applied to electronic devices to respond to user input operations and meet user usage requirements. Specifically, the switch control circuit 100 includes a detection module 110, a power module 120, and a function module 130.

[0036] In an embodiment of the present application, the detection module 110 is used to continuously generate an input signal during the detection of a user's input operation. The user can control the electronic device through input operations. Among them, the input operation may include but is not limited to a press operation, a touch operation, etc. Correspondingly, the detection module may include an elastic component to detect a press operation; the input operation may also include a capacitive detection module to detect a touch operation, which can be specifically set according to actual design needs, and the present application does not limit this.

[0037] In order to reduce the cost of the product and enrich the user experience, the user can control the electronic device through the input operation and the duration of the input operation. The detection module 110 continuously generates an input signal during the period of detecting the user's input operation. That is, the input signal is generated during the continuous process of the input operation; when the input operation ends, the input signal is stopped, so that subsequent control can be performed according to the duration of the input signal.

[0038] The power module 120 is connected to the detection module 110, and is used to connect the power supply to the power supply according to the input signal when receiving the input signal. That is, during the period when the input signal exists, the power module 120 and the power supply will remain in a conductive state.

[0039] The functional module 130 is connected to the power module 120, and the functional module 130 is used to work according to the on-time of the power module 120 when the power module 120 is turned on to the power supply. The power module 120 provides power support for the normal operation of the functional module 130. It can be understood that during the continuous input operation, the power module 120 will remain in the on state, and the on-time of the power module 120 is the maintenance time of the input operation.

[0040] Among them, the functional module 130 can be used to implement one or more functions, such as light changes, sound reminders, etc., and can also be used to adjust the gear position, such as light brightness control, volume level, etc.

[0041] In some implementations, the on-time of the power module 120 may be the working time of the functional module 130 .

[0042] In some implementations, the on-time of the power module 120 may also be used to adjust the function of the functional module 130 .

[0043] In some embodiments, the on-time of the power module 120 may also be used to select a desired gear position.

[0044] Thus, the user can control the working state of the functional module by adjusting the maintenance duration of the input operation without going through the control module. This can not only save the pin resources of the product's control module and effectively reduce costs, but also provide a new design direction for the product and enrich the user experience. The following embodiments will explain this in detail.

[0045] See also Figure 2 , Figure 2 A schematic diagram of the structure of a detection module 110 provided in an embodiment of the present application is shown. Figure 2 As shown, the detection module 110 provided in the embodiment of the present application includes an operation unit 111 and a conversion unit 112 .

[0046] The operation unit 111 is used to receive an input operation from a user and continuously generate a detection signal during the period of receiving the input operation.

[0047] The conversion unit 112 is connected to the operation unit 111 , and is used to convert the detection signal into an input signal.

[0048] In some embodiments, the operating unit 112 is an elastic component; the input operation is a pressing operation, and the operating unit is used to deform when receiving a pressing operation from the user, thereby generating a detection signal. For example, the operating unit 112 is a touch spring. When the user performs a pressing operation, the touch spring is deformed, thereby generating a detection signal. For example, the operating unit generates a detection signal in a capacitive sensing manner. When the touch spring is deformed, the capacitance value changes, thereby generating a detection signal. For another example, the operating unit generates a detection signal in a resistive manner. When the touch spring is deformed, the resistance value changes, thereby generating a detection signal. For another example, when the touch spring of the operating unit is deformed, the contact of the touch spring is connected to the circuit, thereby generating a detection signal. It can be understood that the present application is not limited to this, and the operating unit 112 can also select other components that can perform input operation detection.

[0049] See also Figure 3 , Figure 3 FIG. 1 shows a schematic diagram of the structure of another detection module 110 provided in an embodiment of the present application. Figure 3 As shown, in the detection module 110 provided in the embodiment of the present application, the conversion unit 112 includes a first pin 1121 and a second pin 1122 .

[0050] The first pin 1121 of the conversion unit 112 is connected to the operation unit 111, and the second pin 1122 of the conversion unit 112 is connected to the power module 120. The conversion unit 112 is used to receive the detection signal input by the first pin 1121, convert the detection signal into an input signal, and output the input signal through the second pin 1122.

[0051] In some embodiments, the conversion unit 112 may use an acquisition conversion chip, for example, an analog-to-digital conversion chip that converts an input analog signal into a digital signal, thereby converting the detection signal into a digital signal that can control subsequent modules.

[0052] See also Figure 4 , Figure 4 A schematic diagram of the structure of another detection module provided in an embodiment of the present application is shown. Figure 4 As shown, in the detection module 110 provided in the embodiment of the present application, the conversion unit 112 includes a collection conversion chip U1, and the operation unit 111 includes a touch spring K1.

[0053] When the touch spring K1 receives a pressing operation from the user, it is deformed, the contact is connected to the circuit, the switch is turned on, and a detection signal is generated.

[0054] In some embodiments, the operation unit 111 may also perform filtering operations on the detection signal, such as Figure 4 As shown, the resistor R1 and the capacitor C3 can filter the detection signal. It can be understood that in other implementations, other forms of filtering structures can also be used for filtering, and the present application does not limit this.

[0055] Furthermore, the generated detection signal is input from the first pin 1121 of the acquisition conversion chip U1 , and the first pin 1121 is the TK pin.

[0056] The acquisition conversion chip U1 converts the detection signal into high and low levels for output, and outputs it through the second pin 1122, which is the OUT pin. The high and low levels are set by the TGL pin and AHB pin of the acquisition conversion chip U1. For example, the TGL pin is pulled down to a low level (the TGL pin is grounded through a resistor R4), and the AHB pin is pulled up to a high level (the AHB pin is connected to the power supply VCC through a resistor R2); when the first pin 1121 has a detection signal input, the second pin 1122 outputs a high level; when the first pin 1121 has no detection signal input, the second pin 1122 outputs a low level; the VDD pin is the power supply VCC pin, and the VSS pin is the power supply GND pin.

[0057] It is understandable that in other implementations, the detection module 110 may also adopt other structural designs, and the present application does not limit this.

[0058] See also Figure 5 , Figure 5 FIG. 1 shows a schematic diagram of the structure of a power module provided in an embodiment of the present application. Figure 5 As shown, the power module 120 includes a first switch unit 121 and a second switch unit 122 .

[0059] The first end 1211 of the first switch unit 121 is connected to the first end 1221 of the second switch unit 122 ; the second end 1212 of the first switch unit 121 is connected to the power supply; and the third end 1213 of the first switch unit 121 is connected to the functional module 130 .

[0060] The second end 1222 of the second switch unit 122 is connected to the detection module 110 .

[0061] The second switch unit 122 is used to conduct the path between the first end 1221 and the second end 1222 of the second switch unit 122 when the second end 1222 of the second switch unit 122 receives an input signal, so as to transmit the input signal to the first end of the first switch unit 121.

[0062] The first switch unit 121 is used to connect the path between the second end 1212 and the third end 1212 when the first end 1211 receives an input signal, so as to provide power for the functional module 130. The duration of the user's input operation determines the connection time between the first switch unit 121 and the power supply VCC, and also determines the connection time between the functional module 130 and the power supply VCC.

[0063] See also Figure 6 , Figure 6 FIG. 2 shows a schematic diagram of the structure of another power supply module provided in an embodiment of the present application. Figure 6 As shown, the power module 120 may further include a detection switch unit 123 .

[0064] The first end 1231 of the detection switch unit 123 is used to connect to the control module MCU, and the second end 1232 of the detection switch unit 123 is connected to the detection module 110. The first end of the detection switch unit 123 is a reserved detection interface, which can be used for the MCU to perform switch detection.

[0065] See also Figure 7 , Figure 7 FIG. 2 shows a schematic diagram of the structure of another power module provided in an embodiment of the present application. Figure 7 As shown, the first switch unit 121 includes a MOS tube Q1 and resistors R5 and R6; the second switch unit 122 includes a diode D2; and the third switch unit 123 includes a diode D1.

[0066] Among them, the forward input end of the diode D2 is connected to the detection module 110. When the user does not perform an input operation, the detection module 120 outputs a high level to the reverse end of the diode D2, the gate of the MOS tube Q1 is a high level, the MOS tube Q1 is not turned on, and the path between the power supply VCC and the functional module 130 is disconnected, and the functional module 130 does not work without power support; when the user performs an input operation, the detection module 120 outputs a low level to the reverse end of the diode D2; the diode D2 is turned on, the gate of the MOS tube is a low level, and the MOS tube Q1 is turned on, and the path between the power supply VCC and the functional module 130 is turned on, providing power for the functional module 130 to work. The forward end of the diode D1 can be used to connect to the MCU for switch detection.

[0067] See also Figure 8 , Figure 8 FIG. 1 is a schematic diagram showing a structure of a functional module provided in an embodiment of the present application. Figure 8 As shown, the functional module 130 includes at least one functional unit 131, and the functional unit 131 is used to work when the power module 120 is connected to the power supply, and the working time of the functional unit 131 is the same as the power-on time of the power supply.

[0068] In some embodiments, when the functional module 130 includes multiple functional units 131, the multiple functional units 131 can be connected in parallel, so that the multiple functional units 131 can be connected to the power supply and obtain power from the power supply to work. In other embodiments, the multiple functional units 131 can also be connected in series, or partially in series, or partially in parallel. For example, if the functional unit 131 is a lamp, multiple lamps can be connected in series. The specific design can be based on the actual use requirements of the device and the needs of the user, and this application does not limit this.

[0069] In an embodiment of the present application, when the power module 120 is connected to the power supply, the functional unit 131 obtains power to work, so that the working time of the functional unit 131 is related to the power-on time of the power supply. The user can adjust the duration of the input operation as needed, thereby controlling the working condition of the functional unit 131 and obtaining a rich usage experience.

[0070] In some implementations, the functional unit 131 may be a light strip, a buzzer, etc. The functions of the multiple functional units may be the same, different, or partially the same, and may be specifically configured according to actual use needs, and this application does not limit this.

[0071] In some implementations, the functional module 130 includes a plurality of functional units 131 ; at least one of the plurality of functional units starts working when the power-on duration reaches a preset time threshold, which will be described below with a specific embodiment.

[0072] See also Fig. 9 , Fig. 9 FIG. 2 shows a schematic diagram of another functional module provided in an embodiment of the present application. Fig. 9 As shown, the functional module 130 includes two functional units 131A and 131B, wherein the functional unit 131B starts working when the conduction time of the power supply reaches a preset time threshold. To achieve this purpose, this embodiment adopts a time relay M1, and the normally open switch K1 of the time relay M1 is connected to the path where the functional unit 131B is located. When the time relay M1 is turned on for a preset time threshold, the corresponding normally open switch K1 is actuated (closed), so that the path between the functional unit 131B and the power supply is connected, so that the functional unit 131B obtains electric energy to start working; it can be understood that in other embodiments, other structures can also be used for implementation, and the present application does not limit this.

[0073] It can be understood that in this embodiment, the working time of the functional unit 131A is the same as the conduction time of the power supply. In other implementations, the working mode of the functional unit 131A can also be designed with reference to the functional unit 131B. The above embodiments are only examples and are not limited here.

[0074] In some embodiments, the functional module 130 includes a plurality of functional units 131; each functional unit 131 has a corresponding preset start threshold, and the functional unit 131 is used to start working when the power-on time is equal to the corresponding preset start threshold, and when one functional unit 131 starts working, the other functional units 131 in the plurality of functional units 131 stop working, so that it can be applied to the adjustment of different gears. A specific embodiment will be described below.

[0075] See also Fig.10 , Fig.10 FIG. 2 shows a structural diagram of another functional module provided in an embodiment of the present application. Fig.10 As shown, the functional module 130 includes three functional units 131C, 131D and 131E, and the three functional units are connected in parallel.

[0076] The functional unit 131C corresponds to the first preset time threshold, and the functional module 130 further includes a time relay M2 , and a normally open switch K21 of the time relay M2 is connected in series with the functional unit 131C.

[0077] The function unit 131D corresponds to the second preset time threshold, and the function module 130 further includes a time relay M3, a normally open switch K31 of the time relay M3 is connected in series with the function unit 131D, and a normally closed switch K32 of the time relay M3 is connected in series with the time relay M2.

[0078] The function unit 131E corresponds to the third preset time threshold, and the function module 130 further includes a time relay M4, and a normally open switch K41 of the time relay M4 is connected in series with the function unit 131E. The normally closed switch K42 of the time relay M4 is connected in series with the time relay M2. The normally closed switch K43 of the time relay M4 is connected in series with the time relay M3.

[0079] In the embodiment of the present application, the third preset time threshold is greater than the second preset time threshold, and the second preset time threshold is greater than the first preset time threshold.

[0080] When the power module 120 is connected to the power supply, the path where the time relays M2, M3, and M4 are located is connected. When the conduction time reaches the first preset time threshold, the normally open switch K21 corresponding to the time relay M2 is actuated, the path where the functional unit 131C is located is connected, and the functional unit 131C starts working. At this time, only the functional unit 131C starts working.

[0081] When the conduction time reaches the second preset time threshold, the normally open switch K31 and the normally closed switch K32 corresponding to the time relay M3 are actuated, the path where the functional unit 131D is located is connected, and the functional unit 131D starts working. At the same time, the path where the time relay M2 is located is disconnected, and the path where the functional unit 131C is located is disconnected. At this time, only the functional unit 131D starts working.

[0082] When the conduction time reaches the third preset time threshold, the normally open switch K41, normally closed switches K42, K43 corresponding to the time relay M4 are actuated, the path where the functional unit 131E is located is connected, and the functional unit 131E starts working. At the same time, the paths where the time relays M2 and M3 are located are disconnected, and the paths where the functional units 131C and 131D are located are disconnected. At this time, only the functional unit 131E starts working.

[0083] Among them, the function units 131C, 131D and 131E can correspond to different working gears; for example, the function unit 131C corresponds to the light strip of the first brightness, the function unit 131D corresponds to the light strip of the second brightness, and the function unit 131E corresponds to the light strip of the third brightness. The first brightness is less than the second brightness, and the second brightness is less than the third brightness. Thus, the user can obtain light strip effects of different brightness by controlling the duration of the input operation. It is understandable that the present application is not limited to this, and the specific application can be adjusted as needed, and the present application does not limit this.

[0085] In some implementations, the electronic device 200 may be a mobile phone, a tablet computer, various smart home appliances, etc., so that the cost of the electronic device 200 can be reduced through the switch control circuit 100 and the control method of the electronic device 200 can be enriched.
