[0028] In order to make the purpose, technical solutions and advantages of this application clearer, the following further details this application in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0029] In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more. The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present utility model and the above drawings are intended to distinguish the objects being referred to. For a solution with a time sequence process, this type of term expression does not necessarily need to be understood as describing a specific order or sequence, and for a solution of a device structure, this type of term expression also does not distinguish the importance level, positional relationship, etc.

[0030] In addition, the terms "comprising", "having", and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may also include other steps or units that are inherent to these processes, methods, products, or devices, or steps or units added based on further optimization schemes of the inventive concept of the present utility model.

[0031] As Figure 1 shown, a power-saving circuit includes a battery, a single-chip microcomputer, and at least one key circuit;

[0032] The power supply terminals of the at least one key circuit are respectively connected to the voltage output terminal of the battery, the first output terminals of the at least one key circuit are respectively connected to the power supply terminal of the single-chip microcomputer, and the second output terminals of the at least one key circuit are respectively connected to the key detection pins of the single-chip microcomputer;

[0033] The different key circuits are used to trigger the single-chip microcomputer to send different signals to an external receiving device, and each key circuit includes a key;

[0034] Among them, for any one of the at least one key circuit, when the key of the key circuit is not pressed, the battery is disconnected from the single-chip microcomputer; when the key of the key circuit is pressed, the battery supplies power to the single-chip microcomputer through the key circuit, and the single-chip microcomputer sends the signal corresponding to the key circuit to the external receiving device.

[0035] It should be noted that by using a power-saving circuit provided by the present application, the service life of the battery of a remote control device can be effectively extended. If there is no key press, the storage life of the battery is the standby life of the remote control device.

[0036] A power-saving circuit provided by the present application mainly solves the power-saving problem of remote control devices powered by batteries. When no key is pressed, the device is completely disconnected from the battery, ensuring the longest service time of the battery of the remote control device. When a key is pressed, the single-chip microcomputer gets Vcc power supply and starts to power on and run, checks the key pin. If it is high level, it means this key is in the pressed state; if it is low level, it means this key is in the unpressed state. According to the key state, a signal is sent to the external receiving device.

[0037] Among them, the signals sent by the single-chip microcomputer to the external receiving device include but are not limited to infrared pulse codes, Bluetooth signals, zigbee signals, lora signals, etc., and this embodiment does not make specific limitations on this.

[0038] In the power-saving circuit provided by the present utility model, when the key in the key circuit is not pressed, the connection between the battery and the single-chip microcomputer is completely disconnected, ensuring that the remote control device does not consume power in the non-working state, thereby prolonging the battery life, reducing the static power consumption of the remote control device, and reducing the need for frequent replacement or charging; at the same time, prolonging the battery life not only reduces the user's usage cost, but also reduces battery waste, which is more environmentally friendly.

[0039] In an embodiment of the present application, the number of key detection pins of the single-chip microcomputer is equal to and corresponds one-to-one with the number of the key circuits.

[0040] In an embodiment of the present application, each key circuit corresponds one-to-one with the key detection pin of the single-chip microcomputer, so that the single-chip microcomputer can accurately identify the state of each key, ensuring the reliability and accuracy of different keys triggering different signals.

[0041] As Figure 2 shown, in an embodiment of the present application, the structures of the at least one key circuit are the same;

[0042] The first key circuit in the at least one key circuit includes a first key S1 and a first diode D1.

[0043] It should be noted that, as Figure 3 shown, the at least one key circuit may further include a second key circuit, and the second key circuit includes a second key S2 and a second diode D2.

[0044] In an embodiment of the present application, by unifying the structural design of the key circuit, the circuit design and manufacturing process are simplified, and the production cost and complexity are reduced. At the same time, the standardized circuit structure helps with maintenance and troubleshooting, improving the maintainability and reliability of the power-saving circuit.

[0045] As Figure 2 shown, in an embodiment of the present application, one end of the first key S1 is divided into three paths. One path is connected to the positive electrode of the first diode D1, another path is connected to the input end of the single-chip microcomputer through a first resistor R1, and the third path is grounded through a second resistor R2; the other end of the first key S1 is connected to the voltage output end of the battery;

[0046] The negative electrode of the first diode D1 is connected to the power supply end of the single-chip microcomputer.

[0047] As Figure 3As shown, one end of the second button S2 is divided into three paths. One path is connected to the positive electrode of the second diode D2, another path is connected to the input end of the single-chip microcomputer via the third resistor R3, and the third path is grounded via the fourth resistor R4. The other end of the second button S2 is connected to the voltage output end of the battery. The negative electrode of the second diode D2 is connected to the power supply end of the single-chip microcomputer.

[0048] Among them, the resistance values of the first resistor R1, the second resistor R2, the third resistor R3, and the fourth resistor R4 are all 10 KΩ.

[0049] It should be noted that the models of the first resistor R1, the second resistor R2, the third resistor R3, and the fourth resistor R4 can refer to RC0603FR-0710KL, and the manufacturer is YAGEO (Guoju). This embodiment does not make specific limitations on this.

[0050] As Figure 2 and Figure 3 shown, VBat represents the battery voltage, Vcc represents the power supply voltage of the single-chip microcomputer, GND represents the power supply reference ground of the circuit board, and KeyInput01 and KeyInput02 represent the key detection pins connected to the single-chip microcomputer.

[0051] When the first button S1 is closed, Vcc is powered on, the single-chip microcomputer of the device is powered on, and the program in the single-chip microcomputer starts to run. It is detected that the KeyInput01 signal is at a high level, indicating that S1 is pressed, and the corresponding process of this button is executed.

[0052] In actual use, more key circuits can be expanded according to needs. This embodiment does not make specific limitations on this.

[0053] It should be noted that in the related technology, the startup time of the single-chip microcomputer is within 1 - 10 milliseconds, and it takes 10 milliseconds to send a signal after startup. Within the short time when the button is pressed, the signal can be transmitted. The above circuit only elaborates on the key circuit part for button power saving. The single-chip microcomputer can add a capacitor internally to make the signal stable and extend the working time of the single-chip microcomputer.

[0054] In an embodiment of the present application, the first button S1 is a tactile switch TS-1088-AR02016.

[0055] It should be noted that both the first button S1 and the second button S2 can be tactile switches TS-1088-AR02016, and the manufacturer is XUNPU (Xunpu), or they can be other button switches. This embodiment does not make specific limitations on this.

[0056] In an embodiment of the present application, the first diode D1 is a Schottky diode BAT20JFILM.

[0057] It should be noted that both the first diode D1 and the second diode D2 can be Schottky diodes BAT20JFILM, manufactured by ST (STMicroelectronics), or other diodes. This embodiment does not make specific limitations in this regard.

[0058] In an embodiment of the present application, the signal sent by the single-chip microcomputer to the external receiving device is an infrared pulse signal.

[0059] In an embodiment of the present application, the signal sent by the single-chip microcomputer to the external receiving device is a Bluetooth signal.

[0060] In an embodiment of the present application, the signal sent by the single-chip microcomputer to the external receiving device is a zigbee signal.

[0061] The present application also provides a remote control device, including the above-mentioned power-saving circuit.

[0062] The above embodiments only represent the specific implementation manners of the present invention, and the description is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
