Technical Field

[0001] This utility model relates to the field of switch panel technology, and in particular to a multi-button wireless switch panel. Background Technology

[0002] In recent years, with the increasing variety of smart electrical devices and the widespread adoption of smart home applications, the traditional combination of circuit breakers and panel switches has also undergone significant changes. Through the stable transmission of wired technology and the flexible application of various wireless technologies such as radio frequency, Bluetooth, Wi-Fi, and infrared, users can not only use physical switches but also perform functions such as scene selection, personalized mode settings, and fine-tuning of status conditions through mobile applications. This technological advancement has undoubtedly greatly improved the convenience and technological feel of users' lives, making the living environment more intelligent and humanized.

[0003] However, despite the significant progress made in intelligent technology, the current traditional power switch design is still generally limited to the single-circuit stage. This design can only achieve simple on or off single-state control, and its functionality is relatively limited. It is difficult to meet the diverse and intelligent control needs of modern intelligent electrical equipment. This limitation makes it difficult for traditional power switches to be deeply integrated with intelligent electrical equipment, restricting the improvement of the overall efficiency and user experience of intelligent electrical equipment, and making it difficult for them to be better integrated into intelligent control systems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-button wireless switch panel, which solves the technical problem that traditional power switches are difficult to deeply integrate with smart electrical devices.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-button wireless switch panel for connecting to the live wire and neutral wire of the power output and to the live wire of the current input terminal of the electrical device, including a shell as a mounting carrier, and further including:

[0006] The communication module, located inside the casing, is used for wireless communication with external devices. Users can press several buttons (KEY) to issue corresponding commands to control the pairing status of the communication module with the RF433 remote controller, copy the RF433 code of the RF433 remote controller, and control the switching status of the relay module.

[0007] Several buttons (KEY) are located on the surface of the casing for establishing data communication with the communication module;

[0008] Several sets of relay modules are installed inside the housing on the live wire to receive commands from the communication module and control the on / off state of the line.

[0009] Preferably, the communication module includes a chip M2, with an interface J1 connected to pin 11 of the chip M2 and an interface J2 connected to pin 10 of the chip M2. Several buttons KEY are connected to interfaces J1 and J2.

[0010] Preferably, the housing is provided with several indicator LEDs corresponding to several buttons KEY, and the several indicator LEDs are all connected to interfaces J1 and J2.

[0011] Preferably, each relay module includes a relay switch RY1. Pins 3 and 4 of the relay switch RY1 are connected to the live wire of the power output terminal and the live wire of the electrical equipment input terminal, respectively. A diode D2 is connected between pins 1 and 2 of the relay switch RY1. A transistor Q1 is connected to pin 1 of the relay switch RY1. A resistor R3 is connected between pin 1 of the transistor Q1 and the communication module. A grounded capacitor C5 and a resistor R4 are connected in parallel between pins 1 and 2 of the transistor Q1.

[0012] Preferably, the current input terminal of the communication module is provided with a chip M1 for AC-DC conversion.

[0013] Preferably, the current input terminal of the indicator LED is connected to a power conversion module, which includes a chip U1. A 5V power supply is connected to pin 3 of the chip U1, pin 1 of the chip U1 is grounded, a diode D1 is connected to pin 2 of the chip U1, and a grounded capacitor C1 and a capacitor C2 are connected to pin 2 of the chip U1.

[0014] By employing the above technical solution, this utility model provides a multi-button wireless switch panel, which has at least the following beneficial effects:

[0015] 1. This utility model integrates a communication module, multiple physical buttons (KEYs), and multiple relay modules into a collaborative architecture, thereby integrating traditional switches with smart electrical equipment. The communication module supports Bluetooth Mesh, Wi-Fi networking, and RF433 bidirectional communication, making the panel a network node of an intelligent control system. Multiple independent buttons can simultaneously trigger composite commands such as relay control, device network configuration, and RF code copying through differentiated operations (such as single press / long press / combined press). Multiple relay modules are directly connected in series with the power supply live wire to achieve physical on / off control of different electrical devices.

[0016] 2. This utility model significantly improves the intuitiveness of user operation and the scalability of the system through the coordinated design of multi-functional buttons and indicator lights. Each physical button supports four-level operation logic, namely single press, reverse single press, long press and reverse long press. Different pressing durations and sequences can trigger differentiated functions such as relay switch switching, RF433 remote control code learning, and working mode switching. The indicator lights corresponding to the buttons provide real-time feedback on the device status, such as network configuration mode, copy success and relay on / off status, through flashing frequency, such as slow flash and fast flash, and on / off status.

[0017] 3. This utility model significantly improves the stability and safety of multi-load control through the circuit optimization design of the relay module. Each group of relays uses a transistor drive circuit in conjunction with an RC filter network to effectively suppress false triggering caused by electromagnetic interference. Diode D2 is connected in parallel with the relay coil to eliminate back electromotive force when disconnected to protect the control chip. The relay contacts are directly connected in series with the power supply live wire (pins 3-4) to ensure physical isolation safety. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To address the technical challenge of deeply integrating traditional power switches with smart electrical devices, this application provides a multi-button wireless switch panel, belonging to an AC power control module suitable for multi-load output. It features high-voltage isolation protection and low-voltage signal triggering. This product can be used with any electrical device requiring switching, such as in homes, hotels like Home Inn and Hanting, campsites, serviced apartments, and vehicles. The wireless switch panel connects to the live and neutral wires of the power output and to the live wire of the current input terminal of the electrical device. Figures 1-7 As shown, Figure 7 The dotted lines in the diagram indicate that the two wires do not intersect. The system includes the housing 1, which serves as the mounting carrier, and a communication module 2 housed within the housing 1 for wireless communication with external devices. This module allows the user to press several buttons (KEY) to issue corresponding commands, controlling the pairing status between the communication module 2 and the RF433 remote control, copying the RF433 code from the RF433 remote control, and controlling the switching status of the relay module 3. The following provides a detailed structure of the communication module 2 that meets the functional requirements of this product. It includes a chip M2 (model Ai-WB2-01M), an interface J1 connected to pin 11 of chip M2, an interface J2 connected to pin 10 of chip M2, and several buttons (KEY) connected to interfaces J1 and J2. The surface of the housing 1 has several buttons (KEY) for establishing data communication with the communication module 2. Inside the housing 1, on the live wire, are several sets of relay modules 3 for receiving commands from the communication module 2 and controlling the connection / disconnection of the circuit.

[0029] When using this product, connect the input terminals to the live and neutral wires of the power supply, and the output terminal to the live wire of the device to be controlled or the light control wire. Before wiring, turn off the power switch and use a test pen to confirm that the live and neutral wires are not energized. Ensure electrical safety and insulation. Ideally, the product's internal live wire should have a fuse that controls its on / off state. Therefore, the live and neutral wires must not be reversed to avoid fuse failure or residual current when the product is off, which could cause problems such as residual light when a light bulb is turned off. Afterward, press the KEY button to test whether the live wire can be turned on and off normally. The LED indicator will be constantly lit when on and off when off. It can be preset to automatically turn on after power is supplied. The following example illustrates the reset and network configuration of this product when there are three buttons. There are two common methods. Method 1: Press and hold the middle button for more than 6 seconds. To help users make a judgment, there are several indicator LEDs on the outer casing 1, each corresponding to one of the buttons. These indicator LEDs are connected to interfaces J1 and J2. Release the button after the corresponding indicator LED flashes slowly, and then press it five times. This will clear the copy between the router and the RF433 remote control and enter the network configuration mode. You can then configure the network and add devices on the APP. After the network configuration is complete, the indicator lights will turn off. Method 2: Simply click the reset button on the APP to reset the product and enter the network configuration mode.

[0030] The following further explains the RF433 remote control code copying function, using the three KEY buttons as an example. KEY1, KEY2, and KEY3 have built-in preset RF433 transmission codes, which can be copied to the RF433 remote control's transmission codes. Method one: Press and hold the left, middle, or right button for more than 3 seconds until the corresponding indicator light 1, 2, or 3 flashes rapidly, then release. This will enter RF copying mode. Press the button on the RF433 remote control you want to copy to complete the copy. After copying, the indicator light will turn off. A single press sends a command, while a long press sends multiple commands. If the copy RF mode is exited after a timeout period when the button is released, the copy can be terminated. Alternatively, the APP allows viewing and deleting / adding copied RF433 codes. To add a code, press the button number you want to add, then press the RF433 remote control once to copy. The APP also allows adding codes for each button's action: single press, reverse single press, long press, and reverse long press. A reverse single press sends a single press code after pressing, and releasing and pressing again sends a reverse single press code, repeating this cycle. A reverse long press sends a long press code after pressing, and releasing and pressing again sends a reverse long press code, repeating this cycle.

[0031] In the use of intelligent control systems, several application examples are given to illustrate its practical application: A. A single press copies the automatic opening of the RF electric curtain remote control, a reverse single press copies the automatic closing of the RF electric curtain remote control, a long press copies the manual opening of the RF electric curtain remote control, and a reverse long press copies the manual closing of the RF electric curtain remote control. B. A single press copies the opening of the RF ceiling light remote control, a reverse single press copies the closing of the RF ceiling light remote control, a long press copies the brightness increase of the RF ceiling light remote control, and a reverse long press copies the brightness decrease of the RF ceiling light remote control. If no codes for reverse single press, long press, and reverse long press are set, then only the operation of sending a single press code and continuously sending a single press code is executed.

[0032] The following further explains the configurable switching modes of this product: There are three modes: relay switch mode, RF offline switch mode, and network switch mode. These three modes can be set via the APP. Manual switching allows setting either relay switch mode or RF switch mode. To switch between modes, press and hold the middle button KEY for more than 10 seconds until the corresponding indicator light flashes rapidly, then release and press it five times. After a successful switch, indicator lights 1 / 2 / 3 will flash rapidly three times to indicate a successful switch. The default mode upon power-on is relay switch mode.

[0033] Relay switch mode: Press the switch to turn the corresponding relay on and off. When the relay is on, the corresponding indicator light is always on, and when the relay is off, the corresponding indicator light is off. There is no RF copy and send function in this mode. The mobile APP can also control the on and off of these three relays. In relay switch mode, the APP can perform product relay switch control and query the product control log.

[0034] RF offline switch mode: Enables RF copying and transmission. In this mode, the three relay controls are disabled and forcibly disconnected.

[0035] Network Switch Mode: Used to control the on / off state of other smart devices after connecting to the central gateway, or as a control relay for other RF devices from the central gateway (WIFI / BT TO RF433). It allows for RF code copying and transmission, and allows for adding and deleting RF codes via a mobile app, including single press, reverse single press, long press, and reverse long press codes. In this mode, the three relay controls are disabled and forcibly disconnected.

[0036] The circuit structure of a relay module 3 is described in detail below. Each relay module 3 includes a relay switch RY1. Pins 3 and 4 of the relay switch RY1 are connected to the live wire of the power output terminal and the live wire of the electrical equipment input terminal, respectively. A diode D2 is connected between pins 1 and 2 of the relay switch RY1. A transistor Q1 is connected to pin 1 of the relay switch RY1. A resistor R3 is connected between pin 1 of the transistor Q1 and the communication module 2. A grounded capacitor C5 and a resistor R4 are connected in parallel between pins 1 and 2 of the transistor Q1.

[0037] The communication module 2 has a specific working environment. Therefore, based on its own characteristics, it is necessary to convert the AC power in the power line to DC power before inputting it into the communication module 2. Therefore, the current input terminal of the communication module 2 is equipped with a chip M1 for AC-DC conversion.

[0038] Indicator D4 can only operate under a specific voltage, so the voltage at the input terminal needs to be converted to a specific voltage. Therefore, the current input terminal of the indicator LED is connected to a power conversion module, which includes a chip U1. A 5V power supply is connected to pin 3 of chip U1, pin 1 of chip U1 is grounded, a diode D1 is connected to pin 2 of chip U1, and grounded capacitors C1 and C2 are connected to pin 2 of chip U1.

[0039] Therefore, this product features Bluetooth MESH and WIFI networking, RF433 receiving and transmitting functions, and three built-in relay switches and three actuating switches. It allows for remote real-time on / off control via mobile phone, status feedback for the three relay switches, contextualized control of the three relay switches, and viewing of device control records. It also supports copying standard RF433 remote controls to replace existing remote controls. Through WIFI, BT, and RF433, it connects commercially available RF433 devices to intelligent systems, supports direct control of RF433 devices without a network, and achieves deep integration of power switches and intelligent electrical equipment.
