[0033] In order to make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the specific embodiments of the present application in detail with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0035] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be a middle element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a middle element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation manner.

[0036] The in-wall dimming device proposed by the present application can be an in-wall switch, an in-wall control panel, etc., and is mainly used to control the turning on, turning off, and brightness adjustment of lamps.

[0037] Refer to the attached Figure 1 attachment Figure 1 FIG. shows one of the structural schematic diagrams of the in-wall dimming device 100 in an embodiment of the present application. The in-wall dimming device 100 in this embodiment includes an input module 110, a control module 120, and a dimming module 130; the input module 110 is used to collect control instructions input by the user; the control module 120 is used to output a control signal corresponding to the control instruction to drive the dimming module 130 to control the lamp 200.

[0038] Among them, the input module 110 refers to devices, equipment, modules, etc. that can perform information input, instruction input, and signal input. The input module 110 in this embodiment includes at least one of a voice unit, a first communication unit, a second communication unit, and a touch unit. In other embodiments, the input module 110 may also be other devices that can implement information input, instruction input, and signal input, and is not limited thereto. The communication methods of the first communication unit and the second communication unit are different. Exemplarily, the first communication unit may communicate via WiFi, and the second communication unit may communicate via Bluetooth, and is not limited thereto, as long as it can achieve the purpose of this application.

[0039] It can be understood that, depending on the different input methods of the input module 110, the sources of the corresponding control instructions may also be different. Exemplarily, if the input module 110 includes a voice unit, the control instruction comes from the voice instruction collected by the voice unit. If the input module 110 includes a touch unit, the control instruction comes from the touch instruction collected by the touch unit. If the input module 110 includes the first communication unit and / or the second communication unit, the control instruction comes from the terminal instruction collected by other devices transmitted by the first communication unit and / or the second communication unit, that is, the control instruction includes at least one of a voice instruction, a touch instruction, and a terminal instruction. Further, the above-mentioned voice instruction refers to an electrical signal corresponding to the user's voice information, the touch instruction refers to an electrical signal corresponding to the touch point information input by the user in the touch unit, and the terminal instruction refers to an electrical signal corresponding to the instruction information input by the user in the mobile terminal.

[0040] Since the communication methods of the first communication unit and the second communication unit are different, the paths for transmitting the terminal instructions collected by other devices may also be different. Taking the first communication unit communicating via WiFi and the second communication unit communicating via Bluetooth as an example, the first communication unit is communicatively connected to the cloud, and the cloud transmits the terminal instructions input by the user collected by the mobile terminal to the first communication unit, and the first communication unit then transmits the terminal instruction to the control module 120; the second communication unit can be directly communicatively connected to the mobile terminal, and at this time, the terminal instructions input by the user collected by the mobile terminal can be directly transmitted to the control module 120 through the second communication unit. Exemplarily, refer to the appendix Figure 2 , appendix Figure 2Fig. 0 shows one of the structural schematic diagrams of the input module. In this embodiment, the control instructions include voice instructions and touch instructions; the input module 110 includes a voice unit 111, a first communication unit 112, and a touch unit 113; both the voice unit 111 and the first communication unit 112 are connected to the control module 120; the voice unit 111 is used to collect the user's voice instructions and send the voice instructions to the control module 120, so that the control module 120 transmits the voice instructions to the first communication unit 112; the first communication unit 112 is used to communicate with the cloud 400 to transmit the voice instructions to the cloud 400 and transmit the signal after the cloud 400 parses the voice instructions to the control module 120, so that the control module 120 outputs a corresponding control signal. The touch unit 113 is connected to the control module 120 and is used to collect the touch instructions input by the user and transmit the touch instructions to the control module 120, so that the control module 120 outputs a control signal corresponding to the touch instructions.

[0041] Among them, the voice unit 111 is mainly used to collect the user's voice information and convert it into a corresponding voice instruction in the form of an electrical signal. Exemplarily, the voice unit 111 in this embodiment can use a voice function chip with the model TH2510. The control module 120 further transmits the voice instruction to other data processing modules to obtain the signal after parsing the voice instruction output by other data processing modules, so that the control module 120 outputs a control signal corresponding to the parsed signal.

[0042] The first communication unit 112 can be any communication chip that can communicate with the cloud 400 and the control module 120 respectively. Exemplarily, the first communication unit 112 communicates through WiFi. The voice unit 111 transmits the collected voice instruction to the control module 120, and the control module 120 transmits the voice instruction to the cloud 400 through WiFi for voice parsing. Thus, the cloud 400 outputs a signal corresponding to the voice instruction, and the WiFi module transmits the signal corresponding to the voice instruction to the control module 120. The control module 120 outputs a control signal under the action of the signal corresponding to the voice instruction.

[0043] For example, if the voice uttered by the user is "Help me dim the light to 50%", the voice unit 111 collects the voice and outputs the corresponding voice command to the control module 120. The control module 120 transmits it to the cloud 400 through the first communication unit 112. After parsing the voice command, the cloud 400 outputs the corresponding signal. The first communication unit 112 transmits the signal to the control module 120. Under the action of this signal, the control module 120 outputs a control signal to drive the dimming module 130 to adjust the brightness of the lamp 200 to 50%. It can be seen that through the voice unit 111 in this embodiment, the user can control the lamp 200 by outputting a voice command, improving the intelligence of the in-wall dimming device 100.

[0044] It can be understood that the voice unit 111 generally has a speaker, a microphone, etc. The microphone is mainly used to collect the user's voice. The speaker can be connected to the control module 120 and is used to broadcast a voice indicating successful execution under the control of the control module 120 after the control module 120 outputs a control signal, that is, after the command in the voice command is executed. The broadcast voice can include specific parameters, such as the light brightness is 50%.

[0045] The touch unit 113 can be a touch display screen. The touch unit 113 can collect the touch command input by the user and transmit the touch command to the control module 120 in the form of an electrical signal, so that the control module 120 outputs a control signal corresponding to the touch command, thereby realizing the control of the lamp 200.

[0046] It can be understood that the touch unit 113 can also display the execution parameters under the control of the control signal. For example, if the control signal output by the control module 120 controls the brightness of the lamp 200 to 50%, the information "The brightness of the lamp 200 is 50%" can be displayed in the touch unit 113, thereby enhancing the user experience.

[0047] The control module 120 can be a control chip capable of data processing, logical operation, and signal input and output. Exemplarily, the control module 120 includes but is not limited to an MCU (Microcontroller Unit) chip. The MCU chip is an integrated circuit chip that includes a central processing unit (CPU) and various memories, counters, input / output interfaces, and other functional modules, such as USB, A / D conversion (analog-to-digital conversion), etc., and can output a control signal to realize the control function of other modules (such as the dimming module 130 in this embodiment) and devices.

[0048] The dimming module 130 refers to a circuit or chip that can control the lamp 200. Exemplarily, it can be a power supply switch circuit, which can be turned on or off under the control of a control signal, so as to supply power to the lamp 200 at a preset power-on frequency, thereby realizing the brightness adjustment, turn-on control, and turn-off control of the lamp 200.

[0049] The control signal can be a PWM (Pulse Width Modulation) signal. The control module 120 outputs a PWM signal with a preset duty cycle to the dimming module 130, so that the dimming module 130 supplies power to the lamp 200 at a preset power-on frequency, thereby realizing the control of the lamp 200. It can be understood that the PWM signal includes a high-level signal and a low-level signal. The dimming module 130 is in the powered-on state under the action of the high-level signal (or low-level signal), and is in the powered-off state under the action of the low-level signal (or high-level signal). The alternating frequency of the powered-on state and the powered-off state is the above-mentioned preset power-on frequency. Exemplarily, when the duty cycle of the PWM signal is 0 (or not 0), the dimming module 130 is always in the powered-off state, and at this time the lamp 200 is turned off due to no power supply, so the dimming module 130 can realize the turn-off control of the lamp 200. When the duty cycle of the PWM signal is not 0 (or 0), the dimming module 130 is in the powered-on state when receiving the high-level signal (or low-level signal), and at this time the lamp 200 is turned on due to power supply, so the dimming module 130 can realize the turn-on control of the lamp 200. When the duty cycles of the PWM signals are different, the power-on frequencies of the dimming module 130 are also different, and the corresponding average current or average voltage output to the lamp 200 is also different, so the brightness of the lamp 200 is also different accordingly. Therefore, by outputting PWM signals with different duty cycles, the dimming module 130 can be driven to adjust the brightness of the lamp 200.

[0050] Exemplarily, refer to the appendix Figure 3 , appendix Figure 3The structural schematic diagram of the dimming module 130 is shown. The dimming module 130 includes a first switching tube 131 and a second switching tube 132. The first end of the first switching tube 131 is used to connect to the power module 300. The second end of the first switching tube 131 is connected to the second end of the second switching tube 132. The controlled ends of the first switching tube 131 and the second switching tube 132 are used to connect to the control module 120 to receive control signals. The first end of the second switching tube 132 is used to connect to the lamp 200. Among them, the first switching tube 131 and the second switching tube 132 can be MOS (Metal-Oxide-Semiconductor Field-Effect Transistor) devices, IGBT (Insulated Gate Bipolar Transistor) devices, BJT (Bipolar Junction Transistor) devices, etc. Exemplarily, it can be an N-type MOS device. Among them, the gate of the MOS device serves as the controlled end of the switching tube, the drain of the MOS device serves as the first end of the switching tube, and the source of the MOS device serves as the second end of the switching tube.

[0051] In this embodiment, the user only needs to input a control instruction to the input module 110 in the in-wall dimming device 100 of the present application, and the control module 120 will output a corresponding control signal to control the dimming device, realizing the intelligent control of the lamp 200. Moreover, the input module 110 in the present application includes at least one input method, making the in-wall dimming device 100 of the present application more practical. In addition, since the lamps in traditional families themselves do not belong to smart home products, the in-wall dimming device 100 in this embodiment only needs to remove the original dimming switch and replace it with the in-wall dimming device 100 in this embodiment to replace the original ordinary dimming switch, realizing the intelligent control of the original lamps through multiple channels, without replacing the lamps or modifying the wall.

[0052] In one embodiment, refer to the attached Figure 4 attachment Figure 4 The second structural schematic diagram of the input module 110 in an embodiment of the present application is shown. The control instruction includes a terminal instruction. The in-wall dimming device 100 further includes a first communication unit 112. The first communication unit 112 is connected to the control module 120 and is used to connect to the cloud 400 to receive the terminal instruction sent by the mobile terminal 500 to the cloud 400, and transmit the terminal instruction to the control module 120, so that the control module 120 outputs a control signal corresponding to the terminal instruction.

[0053] Different from the previous embodiment, the first communication unit 112 in this embodiment can receive control instructions from a different source than in the previous embodiment. The terminal instructions transmitted by the first communication unit 112 in this embodiment are from the mobile terminal 500. The mobile terminal 500 can be a mobile intelligent device such as a mobile phone or a computer. The communication method of the first communication unit 112 can be WiFi. The user can send terminal instructions through the mobile terminal 500. The mobile terminal 500 transmits the terminal instructions to the cloud 400. The cloud 400 transmits the terminal instructions to the control module 120 through WiFi, so that the control module 120 outputs a control signal corresponding to the terminal instructions. Through the in-wall dimming device 100 in this embodiment, the user can also control the lamp 200 through the mobile terminal 500, improving the applicability of the in-wall dimming device 100.

[0054] In one embodiment, refer to the attached Figure 5 , the attached Figure 5 shows the third schematic structural diagram of the input module 100 in an embodiment of the present application. The control instructions in this embodiment include terminal instructions; the input module 110 further includes a second communication unit 114. The second communication unit 114 is connected to the control module 120 and is used to connect to the mobile terminal 500 to receive the terminal instructions output by the mobile terminal 500 and send the terminal instructions to the control module 120, so that the control module 120 outputs a control signal corresponding to the terminal instructions.

[0055] Different from the previous embodiment, the instruction transmission path of the second communication unit 114 in this embodiment is different from that of the first communication unit, and the communication method of the second communication unit 114 is different from that of the first communication unit. Exemplarily, the second communication unit 114 in this embodiment communicates with the mobile terminal 500 and the control module 120 through Bluetooth. Different from the first communication unit, the second communication unit 114 can directly communicate with the control module 120 to directly transmit the control instructions output by the user through the mobile terminal 500 to the control module 120, so that the control module 120 outputs a control signal and / or a second control signal corresponding to the control instructions, thereby realizing the control of the lamp 200. Through the in-wall dimming device 100 in this embodiment, when the user is not in a WiFi environment, the lamp 200 can also be controlled through the mobile terminal 500 under the action of the second communication unit 114, enriching the way for the in-wall dimming device 100 to receive control instructions and improving the communication stability between the mobile terminal 500 and the in-wall dimming device 100.

[0056] It can be understood that in some other embodiments, other communication units different from the first communication unit and the second communication unit can also be added to the in-wall dimming device 100 to ensure communication stability. Exemplarily, when the user is not in a WiFi environment and the Bluetooth module of the mobile terminal 500 also fails, the user can still establish a communication connection with the cloud 400 through the mobile network. Similarly, the terminal instruction can be transmitted through the cloud 400, and the cloud 400 then transmits the terminal instruction to the control module 120 through the first communication unit, so that the control module 120 outputs a control signal corresponding to the control instruction, and the like is not limited thereto.

[0057] In one embodiment, refer to the attached Figure 6 , attached Figure 6 shows a schematic structural diagram of the front shell 140, the first PCB board 150, and the second PCB board 160 in an embodiment of the present application. The in-wall dimming device 100 in this embodiment further includes a front shell 140, a first PCB board 150, and a second PCB board 160; the first PCB board 150 is fixed to the back of the front shell 140, and the second PCB board 160 is electrically connected to the first PCB board 150 and is disposed away from the back of the front shell 140; wherein, the first PCB board 150 is provided with a control module 120 and an input module 110; the second PCB board 160 is provided with a dimming module 130.

[0058] Among them, the first PCB board 150 (Printed Circuit Board) and the second PCB board 160 are both carriers for connecting electronic components, and conductive paths are provided therein to electrically connect the control module 120 to the input module 110 and the dimming module 130 respectively. In addition, the first PCB board 150 provided with the control module 120 and the input module 110 is disposed at a position close to the front shell 140, while the second PCB board 160 provided with the dimming module 130 is disposed at a position away from the back of the front shell 140, which can prevent the more vulnerable control module 120 and the gateway module from being damaged.

[0059] In one embodiment, refer to the attached Figure 7 , attached Figure 7 shows another schematic structural diagram of the front shell 140 in an embodiment of the present application. In this embodiment, taking the input module 110 including a touch unit 113 as an example, the front shell 140 is provided with a hollow structure 141; the touch unit 113 is disposed in the hollow structure 141.

[0060] In this embodiment, the touch unit is disposed in the hollow structure 141 of the front shell 140. On the one hand, it is beneficial for the user to directly use the touch unit. On the other hand, it is beneficial to reasonably utilize the space of the front shell 140, reduce the volume of the in-wall dimming device 100, and reduce costs.

[0061] In one embodiment, the input module in this embodiment includes a voice unit; the voice unit includes a speaker, a microphone, and a voice circuit. The speaker and the microphone are disposed on the front surface of the front shell, and the voice circuit is disposed on the first PCB board; wherein, the front surface of the front shell is the side opposite to the back surface of the front shell.

[0062] In this embodiment, disposing the speaker and the microphone on the front surface of the front shell is beneficial for the input module to collect the user's voice commands and broadcast information through the speaker, improving the collection quality of the voice commands. At the same time, disposing the voice circuit on the first PCB board can reduce the conductive path between the voice circuit and the speaker and the microphone, reducing the noise that the circuit may bring.

[0063] In one embodiment, referring to the attached Figure 8 , the attached Figure 8 shows the second schematic structural diagram of the in-wall dimming device 100 in an embodiment of the present application. The in-wall dimming device 100 further includes a bottom shell 170 having a cavity. The bottom shell 170 is detachably connected to the front shell 140; the cavity is used to accommodate the first PCB board and the second PCB board; wherein, the back surface of the front shell 140 and the bottom shell 170 are embedded in the wall (not shown in the attached Figure 9 ) to fix the in-wall dimming device 100, and the front surface of the front shell 140 is exposed from the wall; the front surface of the front shell 140 is the side opposite to the back surface of the front shell 140.

[0064] In this embodiment, setting the bottom shell 170 with a cavity to accommodate the first PCB board and the second PCB board can protect the first PCB board, the second PCB board, the input module 110 and the control module 120 disposed on the first PCB board, and the dimming module 130 disposed on the second PCB board from being damaged by external violence and reducing the service life.
