Description

TECHNICAL FIELD

[0001] The present application relates to the field of remote controller, in particular to a power-saving remote controller and a power-saving method of remote controller. BACKGROUND

[0002] At present, the existing battery remote controller usually needs to replace the battery once every two to three years. The power consumption mainly includes the following three parts:

[0003] Firstly, the battery itself consumes power. The battery will also discharge itself when not in use. Therefore, the ordinary dry battery has a warranty period of only one year.

[0004] Secondly, the standby current of the remote controller consumes power. There is usually no power key on the remote controller, and the remote controller is in a low-power state for a long time. Although the current in the low-power mode is very small, the standby current of most remote controllers still exceeds 1uA. The power consumed by standby per year exceeds 1*24*365 / 1000=8.76mAh.

[0005] Thirdly, when the keys are pressed, the system is in a working state and consumes power. In the working mode, there is usually a current of several milliamperes. If the user's hand does not leave the key, the remote controller will always be in the working mode. If the user operates 50 times a day, presses the key for 0.5 seconds each time, and consumes 5mA each time, the power consumed each year will reach 50*0.5*5*24*365 / 3600=304mAh. SUMMARY

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] In addition, in the description of the present application, "a plurality of" means two or more, unless otherwise specified. The association between the associated objects described by "and / or" indicates that there can be three relationships, for example, A and / or B can represent the three cases of A alone, A and B together, and B alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0037] ReferenceFigures 1-2 , Figures 6-7 A power saving remote controller includes a housing 10, a battery 20, a remote control circuit board 30, etc. The remote control circuit board 30 is installed in the housing 10 and is provided with a CPU 31, at least one function button 32, a transmitting unit 33, etc. The at least one function button 32 is connected to the CPU 31 and is used for inputting a remote control command. The CPU 31 is connected to the transmitting unit 33. After the CPU 31 is powered on, the state of the function button 32 can be detected, and the transmitting unit 33 can be controlled to send a corresponding remote control signal according to the remote control command. The transmitting unit 33 can be a radio frequency transmitting module or an infrared transmitting module, etc. The remote control signal type can be a radio frequency signal or an infrared signal, etc. but is not limited thereto.

[0038] The present application also includes a power supply control button 40 connected between the battery 20 and the CPU 31. The power supply control button 40 is used for controlling the opening or closing of the power supply. When the power supply control button 40 opens the power supply, the power supply path between the battery 20 and the CPU 31 is connected. When the power supply control button 40 closes the power supply, the power supply path between the battery 20 and the CPU 31 is disconnected. Furthermore, the power supply control button 40 is set to be linked with the at least one function button 32. When any function button 32 is pressed, the power supply control button 40 opens the power supply. When the function button 32 is released, the power supply control button 40 closes the power supply, i.e. the remote control circuit board 30 is powered off, and the power supply is physically cut off. In this way, the standby current consumption of the remote control circuit board can be greatly reduced.

[0039] Furthermore, in the present application, when any function button 32 is pressed, the CPU 31 controls the transmitting unit 33 to send a corresponding remote control signal and then enters a low power consumption mode. Until the function button 32 is released and the power supply control button 40 closes the power supply. After the CPU 31 enters the low power consumption mode, it no longer detects the state of the function button 32, and the function button 32 does not serve as a wake-up input. In this way, the power consumption of the remote control circuit board 30 in the working state can be reduced.

[0040] In the present application, the power supply control button 40 and the function button 32 are set to be linked, which can be achieved by a mechanical method or a non-mechanical method. The non-mechanical method can be achieved by software setting. The mechanical method can be achieved by using a key plate, as follows:

[0041] Referring to Figure 6 , Figure 7The top of the shell 10 is provided with at least one function button 32 and a power supply control button 40, and the function button 32 and the power supply control button 40 are spaced apart. The function button 32 and the power supply control button 40 can be realized by common buttons, and the buttons can be automatically returned after being pressed. The number of the function button 32 can be one, two or three according to the control function of the remote control circuit board 30. At least one key plate 50 is arranged on the top of the shell 10, and one end of the key plate 50 is clamped to the shell 10, and the other end of the key plate 50 abuts against the power supply control button 40. The key plate 50 abuts against the function button 32 one by one. When any key plate 50 is pressed or released, the power supply control button 40 and the corresponding function button 32 are pressed or released.

[0042] In the present application, the end of the key plate 50 clamped to the shell 10 can be formed with a fulcrum. Under the action of the external force for pressing the function button 32 and the returning force of the function button 32, the key plate 50 can rotate around the fulcrum during the pressing and releasing process of the key plate 50. The shape of the key plate 50 can be a flat plate or an arc-shaped plate, which can be set according to actual conditions.

[0043] Further, the shell 10 is provided with a mounting seat 11, and the mounting seat 11 is provided with at least one clamping groove 12. The end of the key plate 50 opposite to the clamping groove 12 is provided with a clamping strip 51, and the end of the clamping strip 51 can be hooked to the top wall of the clamping groove 12 to realize clamping. The contact position between the clamping strip 51 and the top wall of the clamping groove 12 can be used as a fulcrum, and the key plate 50 can rotate around the fulcrum by a certain angle. The first protrusion 52 and the second protrusion 53 are arranged on the other end of the key plate 50, respectively. The first protrusion 52 abuts against the power supply control button 40, and the second protrusion 53 abuts against the corresponding function button 32.

[0044] In addition, the mounting seat 11 and the bottom of the shell 10 form a containing cavity 13, and the battery 20 can be located in the containing cavity 13. The remote control circuit board 30 is fixed to the top of the mounting seat 11, and the key plate 50 is arranged above the mounting seat 11 to close the opening of the shell 10, so that the remote control circuit board 30 is not exposed.

[0045] In practical application, two function buttons 32 and two key plates 50 are taken as an example. The two function buttons 32 are arranged on both sides of the power supply control button 40, and the two key plates 50 are arranged on both sides of the top of the shell 10. If the shell 10 is circular as a whole, the two key plates 50 are semicircular. If the shell 10 is rectangular as a whole, the two key plates are rectangular. In addition, the bottom of the shell 10 can be provided with a detachable bottom plate 14 to facilitate the disassembly and assembly of the battery 20.

[0046] In the present application, the battery 20 adopts a lithium manganese battery, which has only 1% self-discharge per year. The CPU 31 can adopt TLSR8366ET24 / QFN24, which can be integrated with the transmitting unit 33. See Figure 2 In the figure, BT2 is the battery 20, KEY1 and KEY2 are the function buttons 32, and KEY0 is the power control button 40. The positive electrode of the battery 20 is connected to one end of the power control button 40, and the other end of the power control button 40 can be connected to the CPU 31. One end of KEY1 and KEY2 is grounded, and the other end can be connected to the CPU 31.

[0047] Based on this, the present application also proposes a power saving method for a remote controller, which adds a power control button 40 on the remote control circuit board 30 and sets the power control button 40 to be linked with at least one function button 32 on the remote control circuit board 30. See Figure 5 In the conventional state, the function button 32 and the power control button 40 are not pressed, the path between the remote control circuit board 30 and the battery 20 is cut off, and the current after power-off can be less than 0.5uA.

[0048] When any function button 32 is pressed, the power control button 40 is linked to turn on the battery power, i.e. the battery 20 supplies power to the remote control circuit board 30. The CPU 31 of the remote control circuit board 30 detects the state of the pressed function button 32 and controls the transmitting unit 33 to send the corresponding remote control signal, and then enters the low-power consumption mode. Until the function button 32 is released, the power control button 40 turns off the power supply of the battery 20. In the low-power consumption mode, the CPU 31 no longer detects the state of the function button 32, i.e. the function button 32 does not serve as a wake-up input.

[0049] The remote controller of the present application can be a remote controller of a bathroom product, such as a smart toilet, but is not limited thereto, and can also be a remote controller of other smart home devices, such as an air conditioner, a television, etc.

[0050] Embodiment Two

[0051] See Figure 3 、 Figure 4 A power saving remote controller and a power saving method for a remote controller, which have the same main structure as Embodiment One, differ in that a solar cell 60 is added for power supply. See BT1 in the figure. Specifically, it includes the solar cell 60, diode D1 and diode D2. The solar cell 60 is arranged in parallel with the battery 20, i.e. the negative electrode of the solar cell 60 is connected to the negative electrode of the battery 20, the positive electrode of the solar cell is connected to the positive electrode of diode D1, the positive electrode of the battery 20 is connected to the positive electrode of diode D2, and the negative electrodes of diode D1 and diode D2 are connected and connected to one end of the power control button 40.

[0052] In the normal state, the function button 32 and the power supply control button 40 are not pressed, the passage between the remote control circuit board 30 and the battery 20 or the solar cell 60 is cut off, and the current after power-off can be less than 0.5uA.

[0053] When any function button 32 is pressed, the power supply control button 40 is linked to turn on the battery power supply 20 or the solar cell power supply 60, that is, the battery 20 or the solar cell 60 supplies power to the remote control circuit board 30, the CPU 31 of the remote control circuit board 30 detects the state of the pressed function button 32 and controls the transmission unit 33 to send the corresponding remote control signal, and then enters the low-power consumption mode until the function button 32 is released, the power supply control button 40 turns off the battery power supply 20 or the solar cell power supply 60. In the low-power consumption mode, the CPU 31 no longer detects the state of the function button 32, that is, the function button 32 does not serve as a wake-up input.

[0054] Further, the working voltage of the solar cell 60 is greater than the working voltage of the battery 20 by 0.1V or more. When the voltage provided by the solar cell 60 is greater than or equal to the voltage provided by the battery 20, diode D1 is turned on and diode D2 is turned off, at which time power is supplied by the solar cell 60; when sunlight is insufficient or the working current is large, the voltage provided by the solar cell 60 is less than the voltage provided by the battery 20, diode D2 is turned on and diode D1 is turned off, at which time power is supplied by the battery 20.

[0055] In this embodiment of the present application, the battery 20 is a lithium-manganese battery, and the solar cell 60 is an amorphous silicon solar cell. Such a solar cell 60 can generate electricity under weak indoor light, so that the open-circuit voltage of the solar cell 60 is higher than the voltage of the battery.

[0056] The present application reduces the standby current of the remote control circuit board 30 by using the power supply control button 40. The remote control circuit board 30 can also be configured to enter the low-power consumption mode immediately after the transmission is completed, thereby reducing the working time and reducing the power consumption. The standby current can also be provided by the solar cell 60, thereby reducing the power consumption of the battery 20.

[0057] The above is only a specific embodiment of the present application, but the design concept of the present application is not limited thereto. Any non-essential modification of the present application using this concept shall be deemed to infringe the protection scope of the present application.
